(Higher infection prevalences are found in Census tracts with lower and higher proportions of Black residents.) Conclusion These results invite provocative conclusions. It appears, for example, that inadequate screening resources may be targeted on Black respondents residing in wealthier neighbourhoods resulting in an elevated prevalence of undiagnosed infection in this subpopulation. A rigorous examination of this and related preliminary results will be presented at the conference.

Rare Case of Mitral Valve and Tricuspid Valve Aneurysm Presented with Progressive Dyspnea

Research Reports in Clinical Cardiology, Mar 1, 2023

Mitral valve aneurysm (MVA) is a saccular, bulging structure of the mitral leaflet that expands d... more Mitral valve aneurysm (MVA) is a saccular, bulging structure of the mitral leaflet that expands during systole and collapses during diastole. Morand provided the first description of the MVA case in 1729. There are no symptoms or indicators particular to an aneurysm in MVA; instead, the clinical findings are comparable to those in mitral regurgitation. Tricuspid valve aneurysms are a bulging or outpouching of the septal leaflet of the tricuspid valve and have been documented in the literature less frequently in association with endocarditis, but as congenital anomaly they have not yet been reported. Case Presentation: We present a case of mitral valve aneurysm and tricuspid aneurysm causing progressive dyspnea. To our knowledge this is the first case of an incidental finding of bilateral atrioventricular valve aneurysm. The patient cardiac findings were limited to mild symptoms and were managed with a medical approach. Conclusion: Atrioventricular aneurysm discovery by accident is infrequent. Shortness of breath and increasing dyspnea may result from this. Only a few cases have been described in the medical literature. In this instance, an unexpected cause of dyspnea in an elderly patient is presented.

Here, we discuss a 24-year-old male with a history of childhood tuberculosis who presented with shortness of breath (SOB), a non-productive cough, and recent weight loss. On examination, he was dyspnoeic but alert. On echocardiographic evaluation, a massive effusion that looked like a massive pericardial effusion was seen, while a further CT scan of the thorax showed a massive unilateral left-sided pleural effusion. Although no tuberculosis (TB) was seen in the sample of thoracocentesis, the patient was referred to a TB centre because of a history of previous tuberculosis and recent weight loss. Pleural effusion and pericardial effusion can be differentiated using echocardiography. In conditions where it is impossible, further imaging, like computer tomography, may be needed to differentiate between them. Keywords:Ple...

Retrospective Analysis of Left Ventricular Thrombus Among Heart Failure Patients with Reduced Ejection Fraction at a Single Tertiary Care Hospital in Somalia

Open Access Emergency Medicine

Left ventricular thrombus (LVT) is a common complication in patients with systolic heart failure ... more Left ventricular thrombus (LVT) is a common complication in patients with systolic heart failure and can cause thromboembolic consequences including stroke. In order to determine the characteristics of LV thrombus among heart failure patients with reduced ejection fraction (HFrEF), the present study was undertaken. Methods and Materials: This was retrospective cross-sectional study conducted from referral tertiary hospital in a year period. A total of 810 transthoracic echocardiograms were carried out in our center from January 2021 to December 2021. Forty participants had met the inclusion criteria of the study. Results: About 75% of the population was male and the mean age at diagnosis was 51 years (SD: 15). Ischemic cardiomyopathy and dilated cardiomyopathy (DCMP) found to be the most underlying cause of LVT represented (57.5% and 42.5% respectively). Hypertension, hypothyroidism, and atrial fibrillation were found to be the commonest associated risk factors of LVT, 45%, 12.5%, and 30% respectively. Simpson's Biplane's approach yielded a mean LVEF of 25.25 ± 6.97. 60% of the patients had a LVEF of ≤25%. The mean LV end-diastolic and end-systolic diameters were 59.2 ± 9.4 mm and 51 ± 8.3mm respectively. Warfarin was administered to 19 (47.5), Rivaroxaban to 8 (20), and Dabigatran to 10 (25). The most prevalent anticoagulant among the individuals in our study was warfarin. A stroke complication was found in 8 patients (20%), two of them were hemorrhagic stroke and they were on dabigatran. A Peripheral Arterial Disease (PAD) affected 6 of the patients (15%). One of those with PAD had also ischemic stroke. This study determines that Ischemic and Dilated cardiomyopathy were the most common cause of left ventricular thrombosis among HFrEF patients in Somalia.

Literature indicates that poor food handling and sanitation practices are more common among food handlers in developing countries resulting in food-borne illness. Hence, food handlers can play a significant role in ensuring food hygiene. To this end, the paper aims to assess the level of food hygiene practices and its associated factors of food handlers working in food establishments in Bole sub-city, Addis Ababa, Ethiopia. Methods: Through across-sectional study design, a total of 394 food handlers selected randomly from food establishments have participated in the study. The data were collected between July and December 2017, through interview and observation. Percentage, cross tabulations, and logistic regressions were used to analyze the data. The findings show that among 394 study subjects only 27.4% (i.e., 108 food handlers), were found to have good food hygiene practices. In other words, majority of food handlers observed were poor in maintaining food hygiene. Food hygiene practices were highly influenced by level score of favorable attitude (AOR = 3.9, 95% CI = 1.93, 7.87), extensive knowledge towards food hygiene (AOR= 3.33, 95% CI= 1.93, 5.76) and availability of water storage equipment at food establishments (AOR= 2.67, 95% CI= 1.38, 5.15). Conclusion: Food handlers had poor food hygiene practices in the study area. Shortages of a continuous water supply at food establishments, poor knowledge, and unfavorable attitude of food handlers towards food hygiene practice were all contributing factors associated with poor food hygiene practice. However, these can be improved through health education programs and environmental health services, such as periodic inspections, effective enforcement of food safety regulations, and enhancing the capacity of food hygiene regulators.

Rival foreign countries present in the Horn of Africa that sought hegemonic dominance, including the USA, China, Turkey, Russia, and the Middle East, watched the political changes that took place in Somalia after the election of President Mohamed Abdullahi Farmajo. However, upon taking the presidential oath, Farmajo's leadership and foreign policy turned towards Turkey and Qatar as an alternative power to lean against in the event of pursuing his irredentist ambitions as was constantly outlined in his rhetorical speech before the election is now on the making. Nevertheless, the revolving question is, would it cause a brief hiatus or hype in Ethiopia's regional hegemonic ambition?

Standard treatment with antimonial injections is long, painful, and costly; has toxic side effects; and is not always available in public hospitals. Small pilot studies have previously evaluated a low-cost and noninvasive hand-held exothermic crystallization thermotherapy for cutaneous leishmaniasis (HECT-CL) device. We aimed to further establish the effectiveness, safety, and feasibility of HECT-CL in L. tropica. In a prospective observational study, patients with parasitological confirmation of CL were treated using the HECT-CL heat pack for 3 minutes with an initial temperature of 52-53°C for 7 consecutive days. Dried blood spot samples were taken for species identification by polymerase chain reaction (PCR). Effectiveness was assessed by using medical photographs and measurements of the lesion size at baseline and subsequent follow-up visits, for up to 180 days. We intended to enroll 317 patients. The HECT-CL treatment was easy to apply and well tolerated. Species identification demonstrated the presence of L. tropica. Interim analysis of 56 patients showed a failure rate of 91% at follow-up (median 45 days after treatment, interquartile range 30-60 days). Enrollment of patients was prematurely suspended because of futility. This study showed a high failure rate for HECT-CL thermotherapy in this setting. Leishmania tropica is known to be less sensitive to antileishmanial drugs, more temperature-resistant, and spontaneous healing is slower than that in L. major. More research is needed to identify low-cost, effective, and more patient-friendly treatment for L. tropica.

We describe the clinical characteristics of the infants admitted between 2013 and 2016 in order to acquire a better understanding on the risk factors for mortality. Methods: We analyzed routinely collected medical data from infants (<7 months) admitted in Chaman and Dera Murad Jamali (DMJ) hospitals. The association between clinical characteristics and mortality was estimated using Poisson regression. Results: Between 2013 and 2016, 5,214 children were admitted (male/female ratio: 1.60) and 1,178 (23%) died. Days since admission was associated with a higher risk of mortality and decreased with each extra day of admission after seven days. The first 48 hours of admission was strongly associated with a higher risk of mortality. A primary diagnosis of tetanus, necrotizing enterocolitis, prematurity, sepsis and hypoxic-ischemic encephalopathy were strongly ...

This mammography system can operate without an anti-scatter grid in place but using software scatter correction instead. This grid-less acquisition mode (PRIME) requires less patient dose due to the increase in primary radiation reaching the detector. This study retrospectively analyses data from the Region of Southern Denmark where the grid-less mode has been installed in November 2013 and replaced grid-based screening. A total of 72,188 screening cases from the same geographical region in Denmark were included in the study. They were subdivided into two study populations: cases acquired before and after installation of the grid-less acquisition mode. Sensitivity and specificity of breast cancer screening were calculated for the two populations; thus representing the perform...

In this paper, MP4-Karver tool is proposed to recover and repair the corrupted videos. Moreover, MP4-Karver extracts frames from video for automatically screen-video to detect illegal cases instead of targeting or watching complete video. Therefore, many existing approaches such as Scalpel's method, Garfienkel, Bi-Fragment Gap Carving, Smart Carving and Frame Based Recovery attempts to recover the videos in different ways, but most of the recovered videos are usually not complete playable. The proposed MP4-Karver focuses on recovery of video files and repair corrupted videos to complete and playable. Experimental results show that the proposed MP4-Karver effectively restores corrupted or damaged video for an improved percentage of the video restoration compared with existing tools.

Objectives To measure the impact of the 2012 Olympics on service use in London Methods Data were gathered from London sexual health services in London for July-September 2012 relating to contraception, sexual assault, sex worker services and telephone sexual health advice Results Emergency contraception prescriptions rose by 20% (from 1086 to 1353) over the Olympic and post-Olympic period as compared to the previous month. In the Brook London contraception clinics there was a 9% rise (from 1209 to 1328) in all attendance over the Olympic period as compared with 2011. In the three main sexual assault services, 1-7% of reported incidents were in clients who were visiting the Olympics. In a survey of 102 sex workers, 59% (59/102) reported fewer clients and 46% (46/102) reported more police interference and brothel closures. Sixteen (16%) were new sex workers and 7% (7/102) came to London specifically for the Olympics. Telephone advice line calls about sexual health fell by 19% (from 741 in the previous month to 622 over the Olympics) then rose by 25% (from 622 to 828) in the month after the Olympics. This increase was mainly due to calls by women with vaginal symptoms (from 112 to 184, 61% increase) and urinary tract problems (from 150 to 223, 67% increase). Conclusions Contraception service use was higher and emergency contraception prescriptions increased following the Olympics. Reported use of sexual assault services, sex workers and telephone advice was low during the Olympics but there was a large rise in requests for sexual health advice afterwards. These data will prove valuable in planning sexual health service provision for cities with large-scale events in the future Sex and the 2012 OlymPicS Part 2.
