CT of the thorax revealed the involvement of 50% of the lungs. Screening ECG and ECHO were normal. The patient was treated with oxygen therapy and drugs and was discharged after 12 days of admission. Post-discharge, the patient remained symptom-free and continued his work. After one month, the patient developed a fever for three days, for which he took antipyretics. Subsequently, the patient developed sudden onset breathlessness, which rapidly progressed to grade 4 NYHA, and developed a cough as well. Suspecting COVID-19 reinfection, the patient visited a nearby hospital, where COVID–19 rt-PCR swabs turned out to be positive, and was referred to our hospital. On receiving, the patient had diffuse lung crepitations and a diastolic murmur in the neo-aortic area. CT thorax revealed pulmonary edema with areas of consolidation. ECHO revealed vegetation on the aortic valve with severe aortic regurgitation. Blood cultures were taken, which revealed the growth of Enterococcus faecalis. The diagnosis of infective endocarditis was made, and the patient was started on appropriate treatment. COVID–19 has effects on various systems, including the cardiovascular system. Even though infective endocarditis is common in the elderly with valvular heart disease, this patient had developed infective endocarditis in an apparently normal aortic valve. Infective endocarditis and COVID–19 can have similar presentations leading to diagnostic difficulties. COVID–19, affecting the heart valves causing valvulitis and predisposing them to the development of infective endocarditis, is also an area to be explored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aortic%20regurgitation" title="aortic regurgitation">aortic regurgitation</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=infective%20endocarditis" title=" infective endocarditis"> infective endocarditis</a>, <a href="https://publications.waset.org/abstracts/search?q=valvulitis" title=" valvulitis"> valvulitis</a> </p> <a href="https://publications.waset.org/abstracts/136281/covid-19-the-cause-or-the-confounder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136281.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Study and Analysis of a Susceptible Infective Susceptible Mathematical Model with Density Dependent Migration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jitendra%20Singh">Jitendra Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Vivek%20Kumar"> Vivek Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a susceptible infective susceptible mathematical model is proposed and analyzed where the migration of human population is given by migration function. It is assumed that the disease is transmitted by direct contact of susceptible and infective populations with constant contact rate. The equilibria and their stability are studied by using the stability theory of ordinary differential equations and computer simulation. The model analysis shows that the spread of infectious disease increases when human population immigration increases in the habitat but it decreases if emigration increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SIS%20%28Susceptible%20Infective%20Susceptible%29%20model" title="SIS (Susceptible Infective Susceptible) model">SIS (Susceptible Infective Susceptible) model</a>, <a href="https://publications.waset.org/abstracts/search?q=migration%20function" title=" migration function"> migration function</a>, <a href="https://publications.waset.org/abstracts/search?q=susceptible" title=" susceptible"> susceptible</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/77503/study-and-analysis-of-a-susceptible-infective-susceptible-mathematical-model-with-density-dependent-migration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77503.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Bilateral Retinitis in Q Fever</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carl%20Eiselen">Carl Eiselen</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephen%20O%E2%80%99Hagan"> Stephen O’Hagan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Q fever, caused by the obligate intracellular bacterium Coxiella burnetii, is an infectious disease with variable systemic manifestations. Its potential to cause ocular complications has not been reported before in Australia. This case study explores the unusual presentation of asymptomatic acute multifocal retinitis (AMR) in a patient with acute Q fever endocarditis and hepatitis in rural Queensland, Australia. Case Presentation: A 48-year-old male gardener presented with flu-like symptoms, weight loss, and encephalopathy. Despite systemic malaise, he had no ocular symptoms. Laboratory investigations confirmed acute Q fever, and imaging studies identified hepatic involvement and endocarditis. The retinal screening revealed asymptomatic AMR, corroborated by fundus examination and SD-OCT. Following treatment with Doxycycline and hydroxychloroquine, both systemic and ocular manifestations improved. Discussion: This is the first documented case of asymptomatic AMR associated with Q fever. The patient’s lack of autoantibodies challenges the established understanding of Q fever endocarditis and suggests potential alternative mechanisms. Conclusion: This case report expands our understanding of the multi-systemic impact of Q fever, highlighting the need for comprehensive clinical evaluation and including retinal screening in the setting of acute infection. The disease's underlying mechanism for ocular involvement is not yet established. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Coxiella%20Burnetti" title="Coxiella Burnetti">Coxiella Burnetti</a>, <a href="https://publications.waset.org/abstracts/search?q=Q%20fever" title=" Q fever"> Q fever</a>, <a href="https://publications.waset.org/abstracts/search?q=ocular%20manifestation" title=" ocular manifestation"> ocular manifestation</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20multifocal%20retintis" title=" acute multifocal retintis"> acute multifocal retintis</a>, <a href="https://publications.waset.org/abstracts/search?q=endocarditis" title=" endocarditis"> endocarditis</a> </p> <a href="https://publications.waset.org/abstracts/178196/bilateral-retinitis-in-q-fever" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178196.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">56</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Stability Analysis of a Human-Mosquito Model of Malaria with Infective Immigrants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Budhwar">Nisha Budhwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunita%20Daniel"> Sunita Daniel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we analyse the stability of the SEIR model of malaria with infective immigrants which was recently formulated by the authors.

Objective: The aim of this study is To estimate the prevalence of cases of Q fever in hospitalized febrile patients in Imam Al Hussain Teaching Medical City in Karbala. Methods: One hundred patients with pyrexia were admitted to the medical ward from 1st August to 31st December 2019. Serological procedures fortified by Enzyme-linked Immunosorbent Assay test. Patients were considered to have acute Q fever when the specific antibodies (IgM and IgG) of phase II of Coxiella burnetii were positive. Results: The mean age of the patients was 35.05±12.93 years; females constituted 60% of them. Eighteen patients (18%) showed positive results for IgM, a lower proportion (13% n=13) had positive IgG levels, and 9% showed equivocal results. Statistical analysis revealed a significant association between positive IgM levels of the female gender and in patients consuming unpasteurized milk. One patient (female aged 60 years) died in the hospital, while all other patients were discharged well. Two female patients were pregnant, and one of them had an abortion. Conclusions: Q fever is more common in febrile patients. The study indicates that this disease should not be overlooked in the differential diagnosis of acute fever. Serological testing should be performed in all patients with acute febrile illness with an unsettling diagnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibodies" title="antibodies">antibodies</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency" title=" frequency"> frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=immunoglobulin%20IgM" title=" immunoglobulin IgM"> immunoglobulin IgM</a>, <a href="https://publications.waset.org/abstracts/search?q=Q%20fever" title=" Q fever"> Q fever</a> </p> <a href="https://publications.waset.org/abstracts/154564/the-frequency-of-q-fever-among-hospitalized-patients-with-pyrexia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154564.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> An Atlantic Canadian Case of Disseminated Streptococcus equi Subspecies zooepidemicus Infection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Albert%20Chang">Albert Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Duncan%20Webster"> Duncan Webster</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Streptococcus equi subspecies zooepidemicus infections in humans can be contracted through contact with domestic animals or unpasteurized dairy products. Although infection in humans is rare, the course can be fulminant. We describe the case of a 75-year-old, immunocompetent male, who developed disseminated disease with bacteremia, native aortic valve endocarditis, suppurative pericarditis with cardiac tamponade, meningitis and bilateral endopthalmitis. Despite treatment with pericardial drain placement, intravenous ceftriaxone and rifampin the patient, unfortunately, did not survive. To date, reported cases of disseminated infection by S. zooepidemicus are few. Furthermore, with the review of the literature, this case demonstrates the broadest organ system involvement reported. Of interest, previous studies have suggested an affinity of this organism for certain organ systems and this case corroborates an emerging association of S. zooepidemicus with endopthalmitis. In addition, this is the second Canadian case of documented human infection with both cases being similar in clinical features, presentation, and geographical location. A discussion regarding previous S. zooepidemicus outbreaks and the potential for zoonotic outbreaks to occur is included. In short, this case report should serve to warn clinicians regarding complications and sites of haematogenous seeding in the setting of disseminated S. zooepidemicus infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endopthalmitis" title="endopthalmitis">endopthalmitis</a>, <a href="https://publications.waset.org/abstracts/search?q=endocarditis" title=" endocarditis"> endocarditis</a>, <a href="https://publications.waset.org/abstracts/search?q=meningitis" title=" meningitis"> meningitis</a>, <a href="https://publications.waset.org/abstracts/search?q=Streptococcus%20equi%20subspecies%20zooepidemicus" title=" Streptococcus equi subspecies zooepidemicus"> Streptococcus equi subspecies zooepidemicus</a> </p> <a href="https://publications.waset.org/abstracts/82114/an-atlantic-canadian-case-of-disseminated-streptococcus-equi-subspecies-zooepidemicus-infection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82114.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Vancomycin Resistance Enterococcus and Implications to Trauma and Orthopaedic Care</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Davies">O.

After an outbreak in the acute trauma and orthopaedic unit in Morriston hospital, we aimed to access the conditions that predispose VRE infections in our unit. Thirteen cases of VRE infection and five cases of VRE colonisations were identified in patients who were treated for orthopaedic care between 1/1/2020 and 1/11/2021. Cases were reviewed to identify predisposing factors, specifically looking at age, presenting condition and treatment, presence of infection and antibiotic care, active haemo-oncological condition, long term renal dialysis, previous hospitalisation, VRE predisposition, and clearance (PREVENT) scores, and outcome of care. The presenting condition, treatment, presence of postoperative infection, VRE scores, age was compared between colonised and the infected cohort. VRE type in both colonised and infection group was Enterococcus Faecium in all but one patient. The colonised group had the same age (T=0.6 P>0.05) and sex (2=0.115, p=0.74), presenting condition and treatment which consisted of peri-femoral fixation or arthroplasty in all patients. The infected group had one case of myelodysplasia and four cases of chronic renal failure requiring dialysis. All of the infected patient had sustained an infected complication of their fracture fixation or arthroplasty requiring reoperation and antibiotics. The infected group had an average VRE predisposition score of 8.5 versus the score of 3 in the colonised group (F=36, p<0.001). PREVENT score was 7 in the infected group and 2 in the colonised group(F=153, p<0.001). Six patients(55%) succumbed to their infection, and one VRE infection resulted in limb loss. In the orthopaedic cohort, VRE infection is a nosocomial condition that has peri-femoral predilection and is seen in association with immunosuppression or renal failure. The VRE infection cohort has been treated for infective complication of original surgery weeks prior to VRE infection. Based on our findings, we advise avoidance of infective complications, change of practice in use of antibiotics and use radical surgery and surveillance for VRE infections beyond infective precautions. PREVENT score shows that the infected group are unlikely to clear their VRE in the future but not the colonised group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surgical%20site%20infection" title="surgical site infection">surgical site infection</a>, <a href="https://publications.waset.org/abstracts/search?q=enterococcus" title=" enterococcus"> enterococcus</a>, <a href="https://publications.waset.org/abstracts/search?q=orthopaedic%20surgery" title=" orthopaedic surgery"> orthopaedic surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=vancomycin%20resistance" title=" vancomycin resistance"> vancomycin resistance</a> </p> <a href="https://publications.waset.org/abstracts/146869/vancomycin-resistance-enterococcus-and-implications-to-trauma-and-orthopaedic-care" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146869.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Cardiovascular Disease Is Common among Patients with Systemic Lupus Erythematosus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fathia%20Ehmouda%20Zaid">Fathia Ehmouda Zaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Reim%20Abudelnbi"> Reim Abudelnbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cardiovascular disease is a major cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE).

Kehinde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: For the diagnosis of prostate cancer Trans-rectal prostate biopsy (TRPB) is used commonly, the procedure is associated with infective complications. There is evidence that antibiotics (ABx) decrease infective events after TRPB, but different regimens are used. Aim: To systematically review different regimens of prophylactic oral antibiotics in TRPB. Design: Medline, Embase, Clinical trials site, and Cochrane library were searched, experts were consulted about relevant studies. Randomized clinical trials (RCT) conducted in the last twenty years, which investigated different oral antibiotic regimens in TRPB, and compared their efficacy to reduce infectious complications were analyzed. Measurements: Primary outcomes were bacteriuria, urinary tract infection (UTI), fever, bacteremia, sepsis. Secondary outcomes were hospitalization rate, and the prevalence of ABx-resistant bacteria. Results: Nine trials were eligible with 3012 patients. Antibiotics prevented bacteriuria (3.5% vs. 9.88%), UTI (4.46% vs. 9.75%), and hospitalization (0.21% vs. 2.13%) significantly in comparison with placebo or no treatment. No significant difference was found in all outcomes of the review between the single dose regimen and the 3 days. The single dose regimen was as effective as the multiple dose except in Bacteriuria (6.75% vs. 3.25%), and the prevalence of ABx-resistant bacteria (1.57% vs. 0.27%). Quinolones reduced only UTI significantly in comparison with other antibiotics. Lastly, Ciprofloxacin is the best Quinolone to prevent UTI, and hospitalization. Conclusion: it is essential to prescribe prophylactic Antibiotics in TRPB. No conclusive evidence could be claimed about the superiority of the multiple or the 3 days regimens to the single dose regimen. Unexpectedly, ABx-resistant bacteria was identified more often in the single dose cohorts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infection" title="infection">infection</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20cancer" title=" prostate cancer"> prostate cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=sepsis" title=" sepsis"> sepsis</a>, <a href="https://publications.waset.org/abstracts/search?q=TRPB" title=" TRPB"> TRPB</a> </p> <a href="https://publications.waset.org/abstracts/34146/oral-antibiotics-in-trans-rectal-prostate-biopsy-and-its-efficacy-to-reduce-infectious-complications-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34146.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">368</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Bronchoscopy and Genexpert in the Diagnosis of Pulmonary Tuberculosis in the Indian Private Health Sector: A Short Case Series</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20J.%20Mathew">J. J. Mathew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pulmonary tuberculosis is highly prevalent in the Indian subcontinent. Most cases of pulmonary tuberculosis are diagnosed with sputum examinations and the vast majority of these are undertaken by the government run establishments. However, mycobacterial cultures are not routinely done, unless drug resistance is detected based on clinical response. Modern diagnostic tests like bronchoscopy and Genexpert are not routinely employed in the government institutions for the diagnosis of pulmonary tuberculosis, but have been accepted widely by good private institutions. The utility of these investigations in the private sector is not yet well recognized. This retrospective study aims to assess the usefulness of bronchoscopy and Genexpert in the diagnosis of pulmonary tuberculosis in quaternary care private hospital in India. 30 patients with respiratory symptoms raising the possibility of tuberculosis based on clinical and radiological features, but without any significant sputum production, were subject to bronchoscopy and BAL samples taken for microbiological studies, including Genexpert. 6 out of the 30 patients were found to be Genexpert positive and none of them showed Rifampicin resistance. All the 6 cases had upper zone predominant disease. One of the 6 cases of tuberculosis had another co-existent bacterial infection according to the routine culture studies. 6 other cases were proven to be due to other bacterial infections alone, 2 had a malignant diagnosis and the remaining cases were thought to be non-infective pathologies. The Genexpert results were made available within 48 hours in the 6 positive cases. All of them were commenced on standard anti-tuberculous regimen with excellent clinical response. The other infective cases were also managed successfully based on the drug susceptibilities. The study has shown the usefulness of these investigations as early intervention enabled diagnosis facilitating treatment and prevention of any clinical deterioration. The study lends support to early bronchoscopy and Genexpert testing in suspected cases of pulmonary tuberculosis without significant sputum production, in a high prevalence country which normally relies on sputum examination for the diagnosis of pulmonary tuberculosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulmonary" title="pulmonary">pulmonary</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bronchoscopy" title=" bronchoscopy"> bronchoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=genexpert" title=" genexpert"> genexpert</a> </p> <a href="https://publications.waset.org/abstracts/47668/bronchoscopy-and-genexpert-in-the-diagnosis-of-pulmonary-tuberculosis-in-the-indian-private-health-sector-a-short-case-series" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47668.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Stability Analysis of SEIR Epidemic Model with Treatment Function</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sasiporn%20Rattanasupha">Sasiporn Rattanasupha</a>, <a href="https://publications.waset.org/abstracts/search?q=Settapat%20Chinviriyasit"> Settapat Chinviriyasit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The treatment function adopts a continuous and differentiable function which can describe the effect of delayed treatment when the number of infected individuals increases and the medical condition is limited.

More than 100 species of mammals, birds and reptiles are involved in the natural cycle of this nematode. At present, T. spiralis, T. pseudospiralis, and T. britovi have been found in Bulgaria. The existence of natural wildlife and domestic reservoirs of Trichinella spp. can be a serious threat to human health. Three trichinella isolates caused human trichinella infection outbreaks from three regions of Sofia City Province were used for the research: sample No. 1 - Ratus norvegicus, sample No. 2 – domestic pig (Sus scrofa domestica), sample No. 3 - domestic pig (Sus scrofa domestica). Trichinella larvae of the studied species were isolated via digestive method (pepsin, hydrochloric acid, water) at 37ºC by standard procedure and were determined by gender (male and female) based on their morphological characteristics. As a reference trichinella species were used: T. spiralis, T. pseudospiralis, T. nativa and T. britovi. Single male and female larvae of the three isolates were crossed with single male and female larvae of the reference trichinella species as well as reciprocally. As a result of cross-breeding, offspring of muscular larvae with T. spiralis and T. britovi were obtained, while in experiments with T. pseudospiralis and T. nativa, trichinella larvae were not found in the laboratory mice. The results obtained in the control groups indicate that the trichinella larvae used from the isolates and the four trichinella species are infective. Also, the infective ability of the F1 offspring from the successful cross-breeding between isolates and reference species was investigated. Through the data obtained in the experiment was found that isolates No. 1 and No. 2 belong to the species T. spiralis, and isolate No. 3 belongs to the species T. britovi. The results were confirmed by PCR and real-time PCR analysis. Thus the presence and circulation of the species T. spiralis and T. britovi in Bulgaria was confirmed. Probably the rodents (rats) are involved in the distribution of T. spiralis in urban environment. The species T. britovi found in a domestic pig speaks of some contact with wild animals for which T. britovi is characteristic. The probable reason is that a large number of farmers in Bulgaria practice the free-range breeding of domestic pigs. Part of the farmers also used as food for domestic pigs waste products from the game (foxes, jackals, bears, wolves) and probably thus the infection was obtained. The distribution range of trichinella species in Bulgaria is not strictly outlined. It is believed that T. spiralis is most common in domestic animals and T. britovi and T. pseudospiralis are characteristic of wildlife. To answer the question whether wild and synanthropic animals are infected with the same or different trichinella species, which species predominate in nature and what their distribution among different hosts is, further research is required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-breeding" title="cross-breeding">cross-breeding</a>, <a href="https://publications.waset.org/abstracts/search?q=Sofia" title=" Sofia"> Sofia</a>, <a href="https://publications.waset.org/abstracts/search?q=trichinellosis" title=" trichinellosis"> trichinellosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Trichinella%20britovi" title=" Trichinella britovi"> Trichinella britovi</a>, <a href="https://publications.waset.org/abstracts/search?q=Trichinella%20spiralis" title=" Trichinella spiralis"> Trichinella spiralis</a> </p> <a href="https://publications.waset.org/abstracts/82286/a-study-of-the-prevalence-of-trichinellosis-in-domestic-and-wild-animals-for-the-region-of-sofia-bulgaria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82286.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Identification of Synthetic Hybrids of 4-Thiazolidinone-Bromopyrrole Alkaloid as HIV-1 RT Inhibitors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20A.%20Rane">Rajesh A.

Similarly, marine bromopyrrole alkaloids are well known for their diverse array of anti-infective properties. Hence, we have reported synthesis and in vitro HIV-1 RT inhibitory activity of a series of 4-thiazolidinone-bromopyrrole alkaloid hybrids tethered with amide linker. The results of in vitro HIV-1 RT kit assay showed that some of the compounds, such as 4c, 4d, and 4i could effectively inhibit RT activity. Among them, compounds 4c having 4-chlorophenyl substituted 4-thiazolidione ring was the best one with the IC50 value of 0.26 µM. The sturdy emerges with key structure-activity relationship that pyrrole-NH-free core benefited inhibition against HIV-1 RT inhibition.

Author tires to elaborate not only the medical, infect plenty of application in other industries. The scope of the research area covers the wide range of physical, biological and chemical sciences that underpin the design of biomaterials and the clinical disciplines in which they are used. A biomaterial is now defined as a substance that has been engineered to take a form which, alone or as part of a complex system, is used to direct, by control of interactions with components of living systems, the course of any therapeutic or diagnostic procedure. Biomaterials are invariably in contact with living tissues. Thus, interactions between the surface of a synthetic material and biological environment must be well understood. This paper reviews the benefits and challenges associated with surface modification of the metals in biomedical applications. The paper also elaborates how the surface characteristics of metallic biomaterials, such as surface chemistry, topography, surface charge, and wettability, influence the protein adsorption and subsequent cell behavior in terms of adhesion, proliferation, and differentiation at the biomaterial–tissue interface. The chapter also highlights various techniques required for surface modification and coating of metallic biomaterials, including physicochemical and biochemical surface treatments and calcium phosphate and oxide coatings. In this review, the attention is focused on the biomaterial-associated infections, from which the need for anti-infective biomaterials originates. Biomaterial-associated infections differ markedly for epidemiology, aetiology and severity, depending mainly on the anatomic site, on the time of biomaterial application, and on the depth of the tissues harbouring the prosthesis. Here, the diversity and complexity of the different scenarios where medical devices are currently utilised are explored, providing an overview of the emblematic applicative fields and of the requirements for anti-infective biomaterials. In addition to this, chapter introduces nanomedicine and the use of both natural and synthetic polymeric biomaterials, focuses on specific current polymeric nanomedicine applications and research, and concludes with the challenges of nanomedicine research. Infection is currently regarded as the most severe and devastating complication associated to the use of biomaterials. Osteoporosis is a worldwide disease with a very high prevalence in humans older than 50. The main clinical consequences are bone fractures, which often lead to patient disability or even death. A number of commercial biomaterials are currently used to treat osteoporotic bone fractures, but most of these have not been specifically designed for that purpose. Many drug- or cell-loaded biomaterials have been proposed in research laboratories, but very few have received approval for commercial use. Polymeric nanomaterial-based therapeutics plays a key role in the field of medicine in treatment areas such as drug delivery, tissue engineering, cancer, diabetes, and neurodegenerative diseases. Advantages in the use of polymers over other materials for nanomedicine include increased functionality, design flexibility, improved processability, and, in some cases, biocompatibility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanomedicine" title="nanomedicine">nanomedicine</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue" title=" tissue"> tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=infections" title=" infections"> infections</a>, <a href="https://publications.waset.org/abstracts/search?q=biomaterials" title=" biomaterials"> biomaterials</a> </p> <a href="https://publications.waset.org/abstracts/48092/biomaterials-solutions-to-medical-problems-a-technical-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48092.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Molecular Docking of Marrubiin in Candida Rugosa Lipase</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benarous%20Khedidja">Benarous Khedidja</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousfi%20Mohamed"> Yousfi Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Infections caused by Candida species manifest in a number of diseases, including candidemia, vulvovaginal candidiasis, endocarditis, and peritonitis. These Candida species have been reported to have lipolytic activity by secretion of lipolytic enzymes such as esterases, lipases and phospholipases. These Extracellular hydrolytic enzymes seem to play an important role in Candida overgrowth. Candidiasis is commonly treated with antimycotics such as clotrimazole and nystatin, which bind to a major component of the fungal cell membrane (ergosterol). This binding forms pores in the membrane that lead to death of the fungus. Due to their secondary effects, scientists have thought of another treatment basing on lipase inhibition but we haven’t found any lipase inhibitors used as candidiasis treatment. In this work, we are interested to lipases inhibitors such as alkaloids as another candidiasis treatment. In the first part, we have proceeded to optimize the alkaloid structures and protein 3D structure using Hyperchem software. Secondly, we have docked inhibitors using Genetic algorithm with GOLD software. The results have shown ten possibilities of binding inhibitor to Candida rugosa lipase (CRL) but only one possibility has been accepted depending on the weakest binding energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marrubiin" title="marrubiin">marrubiin</a>, <a href="https://publications.waset.org/abstracts/search?q=candida%20rugosa%20lipase" title=" candida rugosa lipase"> candida rugosa lipase</a>, <a href="https://publications.waset.org/abstracts/search?q=docking" title=" docking"> docking</a>, <a href="https://publications.waset.org/abstracts/search?q=gold" title=" gold"> gold</a> </p> <a href="https://publications.waset.org/abstracts/2333/molecular-docking-of-marrubiin-in-candida-rugosa-lipase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2333.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Isolation and Identification of Sarcocystis suihominis in a Slaughtered Domestic Pig (Sus scrofa) in Benue State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20I.%20Obadiah">H.

In tissues of the intermediate hosts, the parasites produce sarcocysts that vary in size and morphology according to the species. When a suitable predator ingests sarcocyst-containing meat, the parasites are released in the intestine and undergo sexual reproduction producing infective sporocysts, which are excreted with the feces into the environment. The cycle is closed when a prey ingests sporocyst-contaminated water or pasture; the parasites gain access to the circulation, and eventually invade tissues and reproduce asexually yielding sarcocysts. Pig farming is a common practice in Nigeria as well as in many countries around the world. In addition to its importance as protein source, pork is also a source of several pathogens relevant to humans. In the case of Sarcocystis, three species have been described both in domestic and wild pigs, namely, S. miescheriana, S. porcifelis and S. suihominis. Humans can act both as final and aberrant intermediate hosts of S. suihominis, after ingesting undercooked sarcocyst-infested pork. Infections are usually asymptomatic but can be associated with inappetence, nausea, vomiting and diarrhea, or with muscle pain, fever, eosinophilia and bronchospasm, in humans acting as final or intermediate hosts, respectively. Moreover, excretion of infective forms with human feces leads to further dissemination of the infection. In this study, macroscopic sarcocysts of white color, oval shape and a size range of approximately 3-5 mm were observed in the skeletal muscle of a slaughtered pig in an abattoir in Makurdi, Benue State, Nigeria, destined to human consumption. Sarcocysts were excised and washed in distilled water, and genomic DNA was extracted using a commercial kit. The near-complete length of the 18S rRNA gene was analyzed after PCR amplification of two overlapping fragments, each of which were submitted to direct sequencing. In addition, the mitochondrial cytochrome oxidase (cox-1) gene was PCR-amplified and directly sequenced. Two phylogenetic trees containing the obtained sequences along with available relevant 18S rRNA and cox-1 sequences were constructed by neighbor joining after alignment, using the corresponding sequences of Toxoplasma gondii as outgroup. The results showed in both cases that the analyzed sequences grouped with S. suihominis with high bootstrap value, confirming the identity of this macroscopic sarcocyst-forming parasite as S. suihominis. To the best of our knowledge, these results represent the first demonstration of this parasite in pigs of Nigeria and the largest sarcocysts described so far for S. suihominis. The close proximity between pigs and humans in pig farms, and the frequent poor sanitary conditions in human dwellings strongly suggest that the parasite undergoes the sexual stages of its life cycle in humans as final hosts. These findings provide an important reference for the examination and control of Sarcocystis species in pigs of Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nigeria" title="nigeria">nigeria</a>, <a href="https://publications.waset.org/abstracts/search?q=pork" title=" pork"> pork</a>, <a href="https://publications.waset.org/abstracts/search?q=sarcocystis%20suihominis" title=" sarcocystis suihominis"> sarcocystis suihominis</a>, <a href="https://publications.waset.org/abstracts/search?q=zoonotic%20parasite" title=" zoonotic parasite"> zoonotic parasite</a> </p> <a href="https://publications.waset.org/abstracts/159034/isolation-and-identification-of-sarcocystis-suihominis-in-a-slaughtered-domestic-pig-sus-scrofa-in-benue-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159034.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">88</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Organism Profile Causing Prosthetic Joint Infection Continues to Evolve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bahaa%20Eldin%20Kornah">Bahaa Eldin Kornah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The organism profile for peri-prosthetic joint infection caused by hematogenous seeding or direct inoculations is changing. The organisms that cause prosthetic joint infections range from normal skin colonizers to highly virulent pathogens. The pathogens continue to evolve. While Staphylococcus aureus continues to be the leading organism, gram-negative bacilli account for approximately 7% of cases and that incidence is increasing. Methicillin-resistant S. aureus(MRSA) accounts for approximately 10% of all infections occurring in the community setting and 20% of those in the health care setting. The list of organisms causing PJI has expanded in recent years. It is important to have an understanding of which organisms may be causing a periprosthetic joint infection based on where the patient contracted it and their recent medical history. Also, recent technology has expanded rapidly and new methods to detect the pathogen and why we failed in detecting it. There are a number of explanations for the latter finding, perhaps the most important reason being the liberal use of antibiotics that interferes with the isolation of the infective organism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infection" title="infection">infection</a>, <a href="https://publications.waset.org/abstracts/search?q=periprosthetic" title=" periprosthetic"> periprosthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=hip" title=" hip"> hip</a>, <a href="https://publications.waset.org/abstracts/search?q=organism%20profile" title=" organism profile"> organism profile</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20infection" title=" joint infection"> joint infection</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20infection" title=" joint infection"> joint infection</a> </p> <a href="https://publications.waset.org/abstracts/159166/organism-profile-causing-prosthetic-joint-infection-continues-to-evolve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159166.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Molecular Survey and Genetic Diversity of Bartonella henselae Strains Infecting Stray Cats from Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naouelle%20Azzag">Naouelle Azzag</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Haddad"> Nadia Haddad</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Durand"> Benoit Durand</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Petit"> Elisabeth Petit</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ammouche"> Ali Ammouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Chomel"> Bruno Chomel</a>, <a href="https://publications.waset.org/abstracts/search?q=Henri%20J.%20Boulouis"> Henri J.

In this research, we report the results of a cross sectional study of Bartonella henselae bacteremia in stray cats from Algiers. Whole blood of 227 stray cats from Algiers was tested for the presence of Bartonella species by culture and for the evaluation of the genetic diversity of B. henselae strains by multi-locus variable number of tandem repeats assay (MLVA). Bacteremia prevalence was 17% and only B. henselae was identified. Type I was the predominant type (64%). MLVA typing of 259 strains from 30 bacteremic cats revealed 52 different profiles. 51 of these profiles were specific to Algerian cats/identified for the first time. 20/30 cats (67%) harbored 2 to 7 MLVA profiles simultaneously. The similarity of MLVA profiles obtained from the same cat, neighbor-joining clustering and structure-neighbor clustering showed that such a diversity likely results from two different mechanisms occurring either independently or simultaneously independent infections and genetic drift from a primary strain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bartonella" title="Bartonella">Bartonella</a>, <a href="https://publications.waset.org/abstracts/search?q=cat" title=" cat"> cat</a>, <a href="https://publications.waset.org/abstracts/search?q=MLVA" title=" MLVA"> MLVA</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic" title=" genetic"> genetic</a> </p> <a href="https://publications.waset.org/abstracts/108213/molecular-survey-and-genetic-diversity-of-bartonella-henselae-strains-infecting-stray-cats-from-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108213.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Endoscopic Depiction and Treatment Evaluation of Spirocerca lupi in Dogs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=ELdessouky%20Sheta">ELdessouky Sheta</a>, <a href="https://publications.waset.org/abstracts/search?q=Sayed%20Elzomor"> Sayed Elzomor</a>, <a href="https://publications.waset.org/abstracts/search?q=Haithem%20Farghali"> Haithem Farghali</a>, <a href="https://publications.waset.org/abstracts/search?q=Kawkab%20A.%20Ahmed"> Kawkab A.

Legal medicine investigations are unavoidable when fatalities involve the flight crew or when doubts arise concerning the pilot’s aeromedical health status before the event. As a result of frequently tremendous blunt and sharp force trauma along with the impact of the aircraft to the ground, consecutive blast or fire exposition of the occupants or putrefaction of the dead bodies in cases of delayed recovery, relevant findings can be masked or destroyed and therefor being inaccessible in standard pathology practice comprising just forensic autopsy and histopathology. Such cases are of considerable risk of remaining unsolved without legal consequences for those responsible. Further, no lessons can be drawn from these scenarios to improve flight safety and prevent future mishaps. Aims and Methods: To learn from previously unsolved aircraft accidents, re-evaluations of the investigation files and modern molecular pathology studies were performed. Genetic testing involved predominantly PCR-based analysis of gene regulation, studying DNA promotor methylations, RNA transcription and posttranscriptional regulation. In addition, the presence or absence of infective agents, particularly DNA- and RNA-viruses, was studied. Technical adjustments of molecular genetic procedures when working with archived sample material were necessary. Standards for the proper interpretation of the respective findings had to be settled. Results and Discussion: Additional molecular genetic testing significantly contributes to the quality of forensic pathology assessment in aviation mishaps. Previously undetected cardiotropic viruses potentially explain e.g., a pilot’s sudden incapacitation resulting from cardiac failure or myocardial arrhythmia. In contrast, negative results for infective agents participate in ruling out concerns about an accident pilot’s fitness to fly and the aeromedical examiner’s precedent decision to issue him or her an aeromedical certificate. Care must be taken in the interpretation of genetic testing for pre-existing diseases such as hypertrophic cardiomyopathy or ischemic heart disease. Molecular markers such as mRNAs or miRNAs, which can establish these diagnoses in clinical patients, might be misleading in-flight crew members because of adaptive changes in their tissues resulting from repeated mild hypoxia during flight, for instance. Military pilots especially demonstrate significant physiological adjustments to their somatic burdens in flight, such as cardiocirculatory stress and air combat maneuvers. Their non-pathogenic alterations in gene regulation and expression will likely be misinterpreted for genuine disease by inexperienced investigators. Conclusions: The growing influence of molecular pathology on legal medicine practice has found its way into aircraft accident investigation. As appropriate quality standards for laboratory work and data interpretation are provided, forensic genetic testing supports the medico-legal analysis of aviation mishaps and potentially reduces the number of unsolved events in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aviation%20medicine" title="aviation medicine">aviation medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=aircraft%20accident%20investigation" title=" aircraft accident investigation"> aircraft accident investigation</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic%20pathology" title=" forensic pathology"> forensic pathology</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20pathology" title=" molecular pathology"> molecular pathology</a> </p> <a href="https://publications.waset.org/abstracts/182910/meta-analysis-of-previously-unsolved-cases-of-aviation-mishaps-employing-molecular-pathology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182910.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">44</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Epidemiological, Clinical and Bacteriological Profile of Human Brucellosis in the District of Tunis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jihene%20Bettaieb">Jihene Bettaieb</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghassen%20kharroubi"> Ghassen kharroubi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rym%20mallekh"> Rym mallekh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ines%20Cherif"> Ines Cherif</a>, <a href="https://publications.waset.org/abstracts/search?q=Taoufik%20Atawa"> Taoufik Atawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaouther%20Harrabech"> Kaouther Harrabech</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brucellosis is a major worldwide zoonosis. It is a reportable condition in Tunisia where the disease remains endemic, especially in rural areas. The aim of this study was to describe the epidemiological, clinical, and bacteriological profile of human brucellosis cases notified in the district of Tunis. It was a retrospective descriptive study of cases reported in the district of Tunis through the national surveillance system between the 1st January and 31th December 2017. During the study period, 133 brucellosis confirmed cases were notified. The mean age was 37.5 ± 18.0 years, and 54.9% of cases were males. More than four-fifths (82.7%) of cases were reported in spring and summer with a peak in the month of May (36 cases). Fever and sweats were the most common symptoms; they occurred in 95% and 72% of cases, respectively. Osteoarticular complications occurred in 10 cases, meningitis in one case and endocarditis in one other case. Wright agglutination test and Rose Bengale test were positive in 100% and 91% of cases, respectively. While blood culture was positive in 9 cases and PCR in 2 cases. Brucella melitensis was the only identified specie (9 cases). Almost all cases (99.2%) reported the habit of consuming raw dairy products. Only 5 cases had a suspect contact with animals; among them, 3 persons were livestock breeders. The transmission was essentially due to raw dairy product consumption. It is important to enhance preventive measures to control animal Brucellosis and to educate the population regarding the risk factors of the disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brucellosis" title="brucellosis">brucellosis</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=surveillance%20system" title=" surveillance system"> surveillance system</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/127936/epidemiological-clinical-and-bacteriological-profile-of-human-brucellosis-in-the-district-of-tunis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127936.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Rare Case of Pyoderma Gangrenosum of the Upper Limb</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karissa%20A.%20Graham">Karissa A. Graham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pyoderma gangrenosum (PG) is a prototypic autoinflammatory neutrophilic dermatosis that is a rare disorder. It presents a diagnostic challenge owing to its variable presentation, clinical overlap with other conditions, it is often associated with other systemic conditions, and there is no definitive histological or laboratory characteristic. The Delphai consensus for PG includes the presence of at least one ulcer on the anterior lower limb. Systemic corticosteroids and immunosuppressive therapies are the mainstay treatment for PG. We describe a case report of delayed diagnosis of ulcerative pyoderma gangrenosum in a 44-year-old male on his forearm. The patient presented with an infected ulcer on his right forearm that had been present for over three years. The patient was a Type 2 Diabetic with no personal or family history of inflammatory bowel disease or other autoimmune diseases. The patient was initially investigated for malignancy, but biopsies returned as chronic inflammatory tissue with neutrophilic infiltrate and no malignancy. The patient was commenced on systemic prednisone for the treatment of pyoderma gangrenosum. The diagnosis of ulcerative PG poses a challenge given the vast differential diagnosis for a cutaneous ulcer (i.e., malignant, vascular, autoimmune, trauma, infective, etc.). Diagnostic accuracy is important given that the treatment for PG with steroids does not go without risks and indeed may be contraindicated in other potential causes of the ulcer. Indeed, more common and more sinister causes of ulcers should be investigated first, as death from PG is quite rare. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dermatological%20diagnosis" title="dermatological diagnosis">dermatological diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=dermatosis" title=" dermatosis"> dermatosis</a>, <a href="https://publications.waset.org/abstracts/search?q=pyoderma%20gangrenosum" title=" pyoderma gangrenosum"> pyoderma gangrenosum</a>, <a href="https://publications.waset.org/abstracts/search?q=rare%20presentation" title=" rare presentation"> rare presentation</a> </p> <a href="https://publications.waset.org/abstracts/148767/rare-case-of-pyoderma-gangrenosum-of-the-upper-limb" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148767.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Salmon Diseases Connectivity between Fish Farm Management Areas in Chile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Reche">Pablo Reche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since 1980’s aquaculture has become the biggest economic activity in southern Chile, being Salmo salar and Oncorhynchus mykiss the main finfish species. High fish density makes both species prone to contract diseases, what drives the industry to big losses, affecting greatly the local economy. Three are the most concerning infective agents, the infectious salmon anemia virus (ISAv), the bacteria Piscirickettsia salmonis and the copepod Caligus rogercresseyi. To regulate the industry the government arranged the salmon farms within management areas named as barrios, which coordinate the fallowing periods and antibiotics treatments of their salmon farms. In turn, barrios are gathered into larger management areas, named as macrozonas whose purpose is to minimize the risk of disease transmission between them and to enclose the outbreaks within their boundaries. However, disease outbreaks still happen and transmission to neighbor sites enlarges the initial event. Salmon disease agents are mostly transported passively by local currents. Thus, to understand how transmission occurs it must be firstly studied the physical environment. In Chile, salmon farming takes place in the inner seas of the southernmost regions of western Patagonia, between 41.5ºS-55ºS. This coastal marine system is characterised by western winds, latitudinally modulated by the position of the South-Eats Pacific high-pressure centre, high precipitation rates and freshwater inflows from the numerous glaciers (including the largest ice cap out of Antarctic and Greenland). All of these forcings meet in a complex bathymetry and coastline system - deep fjords, shallow sills, narrow straits, channels, archipelagos, inlets, and isolated inner seas- driving an estuarine circulation (fast outflows westwards on surface and slow deeper inflows eastwards). Such a complex system is modelled on the numerical model MIKE3, upon whose 3D current fields particle-track-biological models (one for each infective agent) are decoupled. Each agent biology is parameterized by functions for maturation and mortality (reproduction not included). Such parameterizations are depending upon environmental factors, like temperature and salinity, so their lifespan will depend upon the environmental conditions those virtual agents encounter on their way while passively transported. CLIC (Connectivity-Langrangian–IFOP-Chile) is a service platform that supports the graphical visualization of the connectivity matrices calculated from the particle trajectories files resultant of the particle-track-biological models. On CLIC users can select, from a high-resolution grid (~1km), the areas the connectivity will be calculated between them. These areas can be barrios and macrozonas. Users also can select what nodes of these areas are allowed to release and scatter particles from, depth and frequency of the initial particle release, climatic scenario (winter/summer) and type of particle (ISAv, Piscirickettsia salmonis, Caligus rogercresseyi plus an option for lifeless particles). Results include probabilities downstream (where the particles go) and upstream (where the particles come from), particle age and vertical distribution, all of them aiming to understand how currently connectivity works to eventually propose a minimum risk zonation for aquaculture purpose. Preliminary results in Chiloe inner sea shows that the risk depends not only upon dynamic conditions but upon barrios location with respect to their neighbors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquaculture%20zonation" title="aquaculture zonation">aquaculture zonation</a>, <a href="https://publications.waset.org/abstracts/search?q=Caligus%20rogercresseyi" title=" Caligus rogercresseyi"> Caligus rogercresseyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chilean%20Patagonia" title=" Chilean Patagonia"> Chilean Patagonia</a>, <a href="https://publications.waset.org/abstracts/search?q=coastal%20oceanography" title=" coastal oceanography"> coastal oceanography</a>, <a href="https://publications.waset.org/abstracts/search?q=connectivity" title=" connectivity"> connectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=infectious%20salmon%20anemia%20virus" title=" infectious salmon anemia virus"> infectious salmon anemia virus</a>, <a href="https://publications.waset.org/abstracts/search?q=Piscirickettsia%20salmonis" title=" Piscirickettsia salmonis"> Piscirickettsia salmonis</a> </p> <a href="https://publications.waset.org/abstracts/101425/salmon-diseases-connectivity-between-fish-farm-management-areas-in-chile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101425.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> A Cost-Benefit Analysis of Routinely Performed Transthoracic Echocardiography in the Setting of Acute Ischemic Stroke</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Rothrock">John Rothrock</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The role of transthoracic echocardiography (TTE) in the diagnosis and management of patients with acute ischemic stroke remains controversial. While many stroke subspecialist reserve TTE for selected patients, others consider the procedure obligatory for most or all acute stroke patients. This study was undertaken to assess the cost vs. benefit of 'routine' TTE. Methods: We examined a consecutive series of patients who were admitted to a single institution in 2019 for acute ischemic stroke and underwent TTE. We sought to determine the frequency with which the results of TTE led to a new diagnosis of cardioembolism, redirected therapeutic cerebrovascular management, and at least potentially influenced the short or long-term clinical outcome. We recorded the direct cost associated with TTE. Results: There were 1076 patients in the study group, all of whom underwent TTE. TTE identified an unsuspected source of possible/probable cardioembolism in 62 patients (6%), confirmed an initially suspected source (primarily endocarditis) in an additional 13 (1%) and produced findings that stimulated subsequent testing diagnostic of possible/probable cardioembolism in 7 patients ( < 1%). TTE results potentially influenced the clinical outcome in a total of 48 patients (4%). With a total direct cost of $1.51 million, the mean cost per case wherein TTE results potentially influenced the clinical outcome in a positive manner was $31,375. Diagnostically and therapeutically, TTE was most beneficial in 67 patients under the age of 55 who presented with 'cryptogenic' stroke, identifying patent foramen ovale in 21 (31%); closure was performed in 19. Conclusions: The utility of TTE in the setting of acute ischemic stroke is modest, with its yield greatest in younger patients with cryptogenic stroke. Given the greater sensitivity of transesophageal echocardiography in detecting PFO and evaluating the aortic arch, TTE’s role in stroke diagnosis would appear to be limited. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardioembolic" title="cardioembolic">cardioembolic</a>, <a href="https://publications.waset.org/abstracts/search?q=cost-benefit" title=" cost-benefit"> cost-benefit</a>, <a href="https://publications.waset.org/abstracts/search?q=stroke" title=" stroke"> stroke</a>, <a href="https://publications.waset.org/abstracts/search?q=TTE" title=" TTE"> TTE</a> </p> <a href="https://publications.waset.org/abstracts/121533/a-cost-benefit-analysis-of-routinely-performed-transthoracic-echocardiography-in-the-setting-of-acute-ischemic-stroke" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121533.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Advanced Techniques in Robotic Mitral Valve Repair</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abraham%20J.%20Rizkalla">Abraham J.

Yan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Durable mitral valve repair is preferred to a replacement, avoiding the need for anticoagulation or re-intervention, with a reduced risk of endocarditis. Robotic mitral repair has been gaining favour globally as a safe, effective, and reproducible method of minimally invasive valve repair. In this work, we showcase the use of the Davinci© Xi robotic platform to perform several advanced techniques, working synergistically to achieve successful mitral repair in advanced mitral disease. Techniques: We present the case of a Barlow type mitral valve disease with a tall and redundant posterior leaflet resulting in severe mitral regurgitation and systolic anterior motion. Firstly, quadrangular resection of P2 is performed to remove the excess and redundant leaflet. Secondly, a sliding leaflet plasty of P1 and P3 is used to reconstruct the posterior leaflet. To anchor the newly formed posterior leaflet to the papillary muscle, CV-4 Goretex neochordae are fashioned using the innovative string, ruler, and bulldog technique. Finally, mitral valve annuloplasty and closure of a patent foramen ovale complete the repair. Results: There was no significant residual mitral regurgitation and complete resolution of the systolic anterior motion of the mitral valve on post operative transoesophageal echocardiography. Conclusion: This work highlights the robotic approach to complex repair techniques for advanced mitral valve disease. Familiarity with resection and sliding plasty, neochord implantation, and annuloplasty allows the modern cardiac surgeon to achieve a minimally-invasive and durable mitral valve repair when faced with complex mitral valve pathology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=robotic%20mitral%20valve%20repair" title="robotic mitral valve repair">robotic mitral valve repair</a>, <a href="https://publications.waset.org/abstracts/search?q=Barlow%27s%20valve" title=" Barlow's valve"> Barlow's valve</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20plasty" title=" sliding plasty"> sliding plasty</a>, <a href="https://publications.waset.org/abstracts/search?q=neochord" title=" neochord"> neochord</a>, <a href="https://publications.waset.org/abstracts/search?q=annuloplasty" title=" annuloplasty"> annuloplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=quadrangular%20resection" title=" quadrangular resection"> quadrangular resection</a> </p> <a href="https://publications.waset.org/abstracts/161021/advanced-techniques-in-robotic-mitral-valve-repair" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161021.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Added Value of 3D Ultrasound Image Guided Hepatic Interventions by X Matrix Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abdel%20Sattar%20Khalil">Ahmed Abdel Sattar Khalil</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazem%20Omar"> Hazem Omar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Image-guided hepatic interventions are integral to the management of infective and neoplastic liver lesions. Over the past decades, 2D ultrasound was used for guidance of hepatic interventions; with the recent advances in ultrasound technology, 3D ultrasound was used to guide hepatic interventions. The aim of this study was to illustrate the added value of 3D image guided hepatic interventions by x matrix technology. Patients and Methods: This prospective study was performed on 100 patients who were divided into two groups; group A included 50 patients who were managed by 2D ultrasonography probe guidance, and group B included 50 patients who were managed by 3D X matrix ultrasonography probe guidance. Thermal ablation was done for 70 patients, 40 RFA (20 by the 2D probe and 20 by the 3D x matrix probe), and 30 MWA (15 by the 2D probe and 15 by the 3D x matrix probe). Chemical ablation (PEI) was done on 20 patients (10 by the 2D probe and 10 by the 3D x matrix probe). Drainage of hepatic collections and biopsy from undiagnosed hepatic focal lesions was done on 10 patients (5 by the 2D probe and 5 by the 3D x matrix probe). Results: The efficacy of ultrasonography-guided hepatic interventions by 3D x matrix probe was higher than the 2D probe but not significantly higher, with a p-value of 0.705, 0.5428 for RFA, MWA respectively, 0.5312 for PEI, 0.2918 for drainage of hepatic collections and biopsy. The complications related to the use of the 3D X matrix probe were significantly lower than the 2D probe, with a p-value of 0.003. The timing of the procedure was shorter by the usage of 3D x matrix probe in comparison to the 2D probe with a p-value of 0.08,0.34 for RFA and PEI and significantly shorter for MWA, and drainage of hepatic collection, biopsy with a P-value of 0.02,0.001 respectively. Conclusions: 3D ultrasonography-guided hepatic interventions by Â x matrix probe have better efficacy, less complication, and shorter time of procedure than the 2D ultrasonography-guided hepatic interventions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D" title="3D">3D</a>, <a href="https://publications.waset.org/abstracts/search?q=X%20matrix" title=" X matrix"> X matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=2D" title=" 2D"> 2D</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonography" title=" ultrasonography"> ultrasonography</a>, <a href="https://publications.waset.org/abstracts/search?q=MWA" title=" MWA"> MWA</a>, <a href="https://publications.waset.org/abstracts/search?q=RFA" title=" RFA"> RFA</a>, <a href="https://publications.waset.org/abstracts/search?q=PEI" title=" PEI"> PEI</a>, <a href="https://publications.waset.org/abstracts/search?q=drainage%20of%20hepatic%20collections" title=" drainage of hepatic collections"> drainage of hepatic collections</a>, <a href="https://publications.waset.org/abstracts/search?q=biopsy" title=" biopsy"> biopsy</a> </p> <a href="https://publications.waset.org/abstracts/173809/added-value-of-3d-ultrasound-image-guided-hepatic-interventions-by-x-matrix-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173809.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Identification of Phenolic Compounds with Antibacterial Activity in Raisin Extract</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20M.%20Abouzeed%20A.%20Elfahem">Yousef M.

Following desiccation, grapes (Vitis vinifera) become more resistant to microbial-based degradation, suggesting that raisins may be a source of antimicrobial compounds. To investigate this hypothesis, total phenolic extracts were obtained from common raisins, local market-sourced. The acetone extract was tested for antibacterial activity against four prevalent bacterial pathogens (Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella spp. and Escherichia coli). Antibiotic sensitivity and the Minimum Inhibitory Concentration (MIC) were determined for each bacterium. High performance liquid chromatography was used to identify compounds in the total phenolic extract. The raisin phenolic extract inhibited growth of all the tested bacteria; the greatest inhibitive effect (normalized to cefotaxime sodium control antibiotic) occurred against P. aeruginosa, followed by S. aureus > Salmonella spp.= E. coli. The phenolic extracts contained the bioactive compounds catechin, quercetin, and rutin. Thus, phytochemicals in raisin extract have antibacterial properties; this plant-based extract, or its bioactive constituents, may represent a promising natural preservative or antimicrobial agent for the food industry or anti-infective drug. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vitis%20vinifera%20raisin" title="Vitis vinifera raisin">Vitis vinifera raisin</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title=" antibacterial activity "> antibacterial activity </a> </p> <a href="https://publications.waset.org/abstracts/18882/identification-of-phenolic-compounds-with-antibacterial-activity-in-raisin-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18882.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">606</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Characterization of Bacteriophage for Biocontrol of Pseudomonas syringae, Causative Agent of Canker in Prunus spp.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mojgan%20Rabiey">Mojgan Rabiey</a>, <a href="https://publications.waset.org/abstracts/search?q=Shyamali%20Roy"> Shyamali Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=Billy%20Quilty"> Billy Quilty</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryan%20Creeth"> Ryan Creeth</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Sundin"> George Sundin</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20W.%20Jackson"> Robert W. Jackson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bacterial canker is a major disease of Prunus species such as cherry (Prunus avium). It is caused by Pseudomonas syringae species including P. syringae pv. syringae (Pss) and P. syringae pv. morsprunorum race 1 (Psm1) and race 2 (Psm2). Concerns over the environmental impact of, and developing resistance to, copper controls call for alternative approaches to disease management. One method of control could be achieved using naturally occurring bacteriophage (phage) infective to the bacterial pathogens. Phages were isolated from soil, leaf, and bark of cherry trees in five locations in the South East of England. The phages were assessed for their host range against strains of Pss, Psm1, and Psm2. The phages exhibited a differential ability to infect and lyse different Pss and Psm isolates as well as some other P. syringae pathovars. However, the phages were unable to infect beneficial bacteria such as Pseudomonas fluorescens. A subset of 18 of these phages were further characterised genetically (Random Amplification of Polymorphic DNA-PCR fingerprinting and sequencing) and using electron microscopy. The phages are tentatively identified as belonging to the order Caudovirales and the families Myoviridae, Podoviridae, and Siphoviridae, with genetic material being dsDNA. Future research will fully sequence the phage genomes. The efficacy of the phage, both individually and in cocktails, to reduce disease progression in vivo will be investigated to understand the potential for practical use of these phages as biocontrol agents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteriophage" title="bacteriophage">bacteriophage</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudomonas" title=" pseudomonas"> pseudomonas</a>, <a href="https://publications.waset.org/abstracts/search?q=bacterial%20cancker" title=" bacterial cancker"> bacterial cancker</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20control" title=" biological control"> biological control</a> </p> <a href="https://publications.waset.org/abstracts/108768/characterization-of-bacteriophage-for-biocontrol-of-pseudomonas-syringae-causative-agent-of-canker-in-prunus-spp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108768.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Assessment of Cardioprotective Effect of Deferiprone on Doxorubicin-Induced Cardiac Toxicity in a Rat Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadaf%20Kalhori">Sadaf Kalhori</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Doxorubicin (DOX)-induced cardiotoxicity is widely known as the most severe complication of anthracycline-based chemotherapy in patients with cancer. It is unknown whether Deferiprone (DFP), could reduce the severity of DOX-induced cardiotoxicity by inhibiting free radical reactions. Thus, this study was performed to assess the protective effect of Deferiprone on DOX-induced cardiotoxicity in a rat model. Methods: The rats were divided into five groups. Group one was a control group. Group 2 was DOX (2 mg/kg/day, every other day for 12 days), and Group three to five which receiving DOX as in group 2 and DFP 75,100 and 150 mg/kg/day, for 19 days, respectively. DFP was starting 5 days prior to the first DOX injection and two days after the last DOX injection throughout the study. Electrocardiographic and hemodynamic studies, along with histopathological examination, were conducted. In addition, serum sample was taken and total cholesterol, Malone dialdehyde, triglyceride, albumin, AST, ALT, total protein, lactate dehydrogenase, total anti-oxidant and creatine kinase were assessed. Result: Our results showed the normal structure of endocardial, myocardial and pericardial in the control group. Pathologic data such as edema, hyperemia, bleeding, endocarditis, myocarditis and pericarditis, hyaline degeneration, cardiomyocyte necrosis, myofilament degeneration and nuclear chromatin changes were assessed in all groups. In the DOX group, all pathologic data was seen with mean grade of 2±1.25. In the DFP group with a dose of 75 and 100 mg, the mean grade was 1.41± 0.31 and 1±.23, respectively. In DFP group with a dose of 150, the pathologic data showed a milder change in comparison with other groups with e mean grade of 0.45 ±0.19. Most pathologic data in DFP groups showed significant changes in comparison with the DOX group (p < 0.001). Discussion: The results also showed that DFP treatment significantly improved DOX-induced heart damage, structural changes in the myocardium, and ventricular function. Our data confirm that DFP is protective against cardiovascular-related disorders induced by DOX. Clinical studies are needed to be involved to examine these findings in humans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiomyopathy" title="cardiomyopathy">cardiomyopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=deferiprone" title=" deferiprone"> deferiprone</a>, <a href="https://publications.waset.org/abstracts/search?q=doxorubicin" title=" doxorubicin"> doxorubicin</a>, <a href="https://publications.waset.org/abstracts/search?q=rat" title=" rat"> rat</a> </p> <a href="https://publications.waset.org/abstracts/116838/assessment-of-cardioprotective-effect-of-deferiprone-on-doxorubicin-induced-cardiac-toxicity-in-a-rat-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116838.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Minimally Invasive versus Conventional Sternotomy for Aortic Valve Replacement: A Systematic Review and Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Shaboub">Ahmed Shaboub</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Jasim%20Althawadi"> Yusuf Jasim Althawadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shadi%20Alaa%20Abdelaal"> Shadi Alaa Abdelaal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hussein%20Abdalla"> Mohamed Hussein Abdalla</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatem%20Amr%20Elzahaby"> Hatem Amr Elzahaby</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Mohamed"> Mohamed Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazem%20S.%20Ghaith"> Hazem S.

Methods: We conducted a PRISMA-compliant systematic review and meta-analysis. We ran an electronic search of PubMed, Cochrane CENTRAL, Scopus, and Web of Science to identify the relevant published studies. Data were extracted and pooled as standardized mean difference (SMD) or risk ratio (RR) using StataMP version 17 for macOS. Results: Forty-one studies with a total of 15,065 patients were included in this meta-analysis (minimally invasive approaches n=7231 vs. conventional sternotomy n=7834). The pooled effect size showed that minimally invasive approaches had lower mortality rate (RR 0.76, 95%CI [0.59 to 0.99]), intensive care unit and hospital stays (SMD -0.16 and -0.31, respectively), ventilation time (SMD -0.26, 95%CI [-0.38 to -0.15]), 24-h chest tube drainage (SMD -1.03, 95%CI [-1.53 to -0.53]), RBCs transfusion (RR 0.81, 95%CI [0.70 to 0.93]), wound infection (RR 0.66, 95%CI [0.47 to 0.92]) and acute renal failure (RR 0.65, 95%CI [0.46 to 0.93]). However, minimally invasive approaches had longer operative time, cross-clamp, and bypass times (SMD 0.47, 95%CI [0.22 to 0.72], SMD 0.27, 95%CI [0.07 to 0.48], and SMD 0.37, 95%CI [0.20 to 0.45], respectively). There were no differences between the two groups in blood loss, endocarditis, cardiac tamponade, stroke, arrhythmias, pneumonia, pneumothorax, bleeding reoperation, tracheostomy, hemodialysis, or myocardial infarction (all P>0.05). Conclusion: Current evidence showed higher safety and better operative outcomes with minimally invasive aortic valve replacement compared to the conventional approach.
