arding this uncommon type of tumors.We aimed to assess the reliability of a screening questionnaire for Active Pulmonary Tuberculosis (APTB) in a population of sheltered homeless persons (HP). Participants from two homeless shelters completed a questionnaire specially designed to identify patients at high-risk of APTB (available at www.tb-screen.ch), underwent a Chest X-ray (CXR), and provided sputum samples. Computed Tomography (CT) scanning was subsequently performed on those which had images consistent with APTB. Microscopical examination, real-time polymerase chain reaction (qPCR) and culture testing were applied for Mycobacterium tuberculosis complex detection. Additionally, we retrospectively selected 16 HP hospitalised in our hospital between 2017 and 2019 with biologically confirmed tuberculosis and typical CXR images, and retrospectively documented a screening questionnaire by reviewing their medical files. Overall, the population (n = 383 HP) was predominantly migrants (87%). Forty-seven individuals (11.7%) had positive screening questionnaire scores and four (2.4%) displayed abnormal CXR features consistent with APTB. Three of them three underwent CT scanning that ruled out APTB and one was lost to follow-up. None tested positive through microbiological investigation. Fifteen (of 16, 93.8%) hospitalised patients with biologically confirmed APTB had a positive screening questionnaire score. The sensitivity and specificity of questionnaire for confirmed APTB were 93.8% and 87.7%, respectively. Screening questionnaires can be used as a first assessment tool in people arriving at homeless shelters and to refer those screening positive for a CXR.Coexisting conditions are relatively common in children with cancer, however, there is a paucity of information on the prevalence of coexisting conditions in children with cancer in South Africa. This cross-sectional study aimed at investigating the common coexisting conditions occurring in children and adolescents younger than 19 years undergoing cancer chemotherapy in a section of the South African private health sector. Medicine claims data from 1 January 2008 to 31 December 2017 were queried to identify coexisting conditions using the International Classification of Diseases, Tenth Revision (ICD-10) codes indicated on reimbursed claims. Where ICD-10 codes per claim were non-specific, the pharmacological drug classes of non-cytotoxic medications claimed alongside these codes were categorized using the Monthly Index of Medical Specialties (MIMS) classification system and analyzed using the drug utilization 90% (DU90%) principle. Analysis of sub-pharmacologic drug classes was stratified according to gender ad adolescent cancer care to curb antimicrobial infections.

Coronary Artery Disease (CAD) is the foremost single cause of mortality and loss of Disability Adjusted Life Years (DALYs) globally. A large percentage of this burden is found in low and middle income countries. This accounts for nearly 7 million deaths and 129 million DALYs annually and is a huge global economic burden.

Review of the results of studies reveals the absolute global and regional trends of the CAD and the importance and contribution of CAD for global health. Data demonstrates which region or countries have the highest and lowest age-standardized DALY rates and what factors might explain these patterns. Results also show differences among the determinants of CAD, government policies, clinical practice and public he The incidence of CAD continues to fall in developed countries over the last few decades and this may be due to both effective treatment of the acute phase and improved primary and secondary preventive measures. Developing countries show considerable variability in the incidence of CAD. The globalization of the Western diet and increased sedentary lifestyle will have a dramatic influence on the progressive increase in the incidence of CAD in these countries.The COVID-19 pandemic is one of unmatched scale and severity. A continued state of crisis has been met with poor public adherence to preventive measures and difficulty implementing public health policy. This study aims to identify and evaluate the factors underlying such a response. Thus, it assesses the knowledge, perceived risk, and trust in the sources of information in relation to the novel coronavirus disease at the outset of the COVID-19 pandemic. An online questionnaire was completed between March 20 and 27, 2020. Knowledge, perceptions, and perceived risk (Likert scale) were assessed for 737 literate participants of a representative sample in an urban setting. We found that respondents' risk perception for novel coronavirus disease was high. The perceived risk score for both cognitive and affective domains was raised at 2.24 ± 1.3 (eight items) and 3.01 ± 1 (seven items) respectively. Misconceptions and gaps in knowledge regarding COVID-19 were noted. Religious leadership was the least trusted (10%) while health authorities were the most trusted (35%) sources of information. Our findings suggest that there was a deficiency in knowledge and high concern about the pandemic, leading to a higher risk perception, especially in the affective domain. Thus, we recommend comprehensive education programs, planned intensive risk communication, and a concerted effort by all stakeholders to mitigate the spread of disease. The first of its kind in the region, this study will be critical to response efforts against current and future outbreaks.Countries in the Middle-East (ME) are tackling two corona virus outbreaks simultaneously, Middle-Eastern Respiratory Syndrome Coronavirus (MERS-CoV) and the current Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Both viruses infect the same host (humans) and the same cell (type-II alveolar cells) causing lower respiratory illnesses such as pneumonia. Molecularly, MERS-CoV and SARS-CoV-2 enter alveolar cells via spike proteins recognizing dipeptidyl peptidase-4 and angiotensin converting enzyme-II, respectively. this website Intracellularly, both viruses hide in organelles to generate negative RNA strands and initiate replication using very similar mechanisms. At the transcription level, both viruses utilise identical Transcription Regulatory Sequences (TRSs), which are known recombination cross-over points during replication, to transcribe genes. Using whole genome alignments of both viruses, we identify clusters of high sequence homology at ORF1a and ORF1b. Given the high recombination rates detected in SARS-CoV-2, we speculate that in co-infections recombination is feasible via TRS and/or clusters of homologies.
