The future of the pediatric workforce has been the subject of significant dialogue in the pediatric community and generated much discussion in the academic literature. There are significant concerns regarding the ability of pediatricians to meet the growing demands of our pediatric population. Over the past 5 years, there has been a decline in the percentage of doctor of osteopathic medicine students who pursue a career in pediatrics but an equally important increase in the number of pediatric positions that are filled by doctor of osteopathic medicine students and international medical graduates. Although there has been an increase in the number of pediatric positions offered in the National Resident Matching Program, the last 4 years have seen a significant increase in the number of unfilled pediatric positions. A number of pediatric subspecialties struggle to fill their training positions, and those with low match rates may have 20% to 40% fewer applicants than positions. The pediatric vision for the future must include a commitment to a comprehensive strategic planning process with the many organizations involved across the multiple stages of the educational continuum. It is time to elucidate and address the questions raised by the workforce data. Developing solutions to these questions will require a careful planning process and a thoughtful analysis of the pediatric workforce data. Establishing this as an important priority will require a major collaborative effort between pediatric academic and professional organizations, but the future benefit to the nation's children will be significant.

In South Africa, tuberculosis (TB) is a leading cause of death among those <20 years of age. We describe changes in TB mortality among children and adolescents in South Africa over a 13-year period, identify risk factors for mortality, and estimate excess TB-related mortality.

Retrospective analysis of all patients <20 years of age routinely recorded in the national electronic drug-susceptible TB treatment register (2004-2016). We developed a multivariable Cox regression model for predictors of mortality and used estimates of mortality among the general population to calculate standardized mortality ratios (SMRs).

Between 2004 and 2016, 729 463 children and adolescents were recorded on TB treatment; 84.0% had treatment outcomes and 2.5% (18 539) died during TB treatment. The case fatality ratio decreased from 3.3% in 2007 to 1.9% in 2016. In the multivariable Cox regression model, ages 0 to 4, 10 to 14, and 15 to 19 years (compared with ages 5 to 9 years) were associated with increased risk of morently needed.Cardiovascular disease (CVD) is one of the leading causes of death across the world. CVD can lead to angina, heart attacks, heart failure, strokes, and eventually, death; among many other serious conditions. The early intervention with those at a higher risk of developing CVD, typically with statin treatment, leads to better health outcomes. For this reason, clinical prediction models (CPMs) have been developed to identify those at a high risk of developing CVD so that treatment can begin at an earlier stage. Currently, CPMs are built around statistical analysis of factors linked to developing CVD, such as body mass index and family history. The emerging field of machine learning (ML) in healthcare, using computer algorithms that learn from a dataset without explicit programming, has the potential to outperform the CPMs available today. ML has already shown exciting progress in the detection of skin malignancies, bone fractures and many other medical conditions. In this review, we will analyse and explain the CPMs currently in use with comparisons to their developing ML counterparts. We have found that although the newest non-ML CPMs are effective, ML-based approaches consistently outperform them. However, improvements to the literature need to be made before ML should be implemented over current CPMs.Medical schools in the UK typically use prior academic attainment and an admissions test (University Clinical Aptitude Test (UCAT), Biomedical Admissions Test (BMAT) or the Graduate Medical School Admissions Test (GAMSAT)) to help select applicants for interview. To justify their use, more information is needed about the predictive validity of these tests. Thus, we investigated the relationship between performance in admissions tests and the Membership of the Royal College of Surgeons (MRCS) examination.The UKMED database (https//www.ukmed.ac.uk) was used to access medical school selection data for all UK graduates who attempted MRCS Part A (n=11 570) and Part B (n=5690) between 2007 and 2019. Univariate and multivariate logistic regression models identified independent predictors of MRCS success. Pearson correlation coefficients examined the linear relationship between test scores and MRCS performance.Successful MRCS Part A candidates scored higher in A-Levels, UCAT, BMAT and GAMSAT (p less then 0.05). No significant differences were observed for MRCS Part B. All admissions tests were found to independently predict MRCS Part A performance after adjusting for prior academic attainment (A-Level performance) (p less then 0.05). Admission test scores demonstrated statistically significant correlations with MRCS Part A performance (p less then 0.001).The utility of admissions tests is clear with respect to helping medical schools select from large numbers of applicants for a limited number of places. Additionally, these tests appear to offer incremental value above A-Level performance alone. We expect this data to guide medical schools' use of admissions test scores in their selection process.

Snake bite continues to be a significant cause of acute kidney injury (AKI) in India. There is paucity of data regarding long-term outcomes of such patients. In this study, we aim to assess the prognosis and long-term renal outcomes of such patients.

We analysed the hospital records of snake envenomation-induced AKI from January 2015 to December 2018. Predictors of in-hospital mortality were assessed. Survivors were advised to visit follow-up clinic to assess their kidney function.

There were 769 patients with evidence of envenomation and of them, 159 (20.7%) had AKI. There were 112 (70.4%) males. Mortality occurred in 9.4% of patients. Logistic regression analysis identified shock (OR 51.949, 95% CI 4.297 to 628.072) and thrombocytopenia (OR 27.248, 95% CI 3.276 to 226.609) as predictors of mortality. Forty-three patients attended the follow-up. The mean follow-up duration was 30.4±15.23 months. Adverse renal outcomes (eGFR <60 mL/min/1.73 m

or new-onset hypertension (HTN) or pre-HTN or urine protein creatinine ratio >0.3) occurred in 48.8% of patients. Older age (mean age (years) 53.3 vs 42.8, p=0.004) and longer duration on dialysis (median duration (days) 11.5 vs 5, p=0.024) were significantly associated with adverse renal outcomes.

The incidence of AKI in snake envenomation was 20.7%. The presence of shock and thrombocytopenia were associated with mortality. Adverse renal outcomes occurred in 48.8% of patients in the long term.

Social distancing measures changed this. The Cleveland Clinic Internal Medicine Residency Programme (IMRP) is one of the largest programmes in the USA, which made the task of implementing a telemedicine curriculum more complex. Here we describe our experience implementing an effective, expedited telemedicine curriculum for our ambulatory resident clinics. This study was started in April 2020 when we implemented a resident-led curriculum and training programme for providing ambulatory telemedicine care. The curriculum was finalised in less than 5 weeks. It entailed introducing a formal training programme for residents, creating a resource guide for different video communication tools and training preceptors to safely supervise care in this new paradigm. GSK2256098 purchase Residents were surveyed before the curriculum to assess prior experience with telemedicine, and then afterward to assess the curriculum's effectiveness. We also created a mini-CEX assessment for residents to solicit feedback on their performance during virtual appointments. Over 2000 virtual visits were performed by residents in a span of 10 weeks. Of 148 residents, 38% responded to the pre-participation survey. A majority had no prior telemedicine experience and expressed only slight comfort with the modality. Through collaboration with experienced residents and faculty, we expeditiously deployed an enhancement to our ambulatory care curriculum to teach residents how to provide virtual care and help faculty with supervision. We share our insights on this experience for other residency programmes to use.Chagas disease (American trypanosomiasis) is a 'neglected' pathology that affects millions of people worldwide, mainly in Latin America. Trypanosoma cruzi, the causative agent, is an obligate intracellular parasite with a complex and diverse biology that infects several mammalian species, including humans. Because of genetic variability among strains and the presence of four biochemically and morphologically distinct parasite forms, the outcome of T. cruzi infection varies considerably depending on host cell type and parasite strain. During the initial contact, cellular communication is established by host-recognition-mediated responses, followed by parasite adherence and penetration. For this purpose, T. cruzi expresses a variety of proteins that modify the host cell, enabling it to safely reach the cytoplasm. After entry into the host cell, T. cruzi forms a transitory structure termed 'parasitophorous vacuole' (PV), followed by its cytoplasmic replication and differentiation after PV rupture, and subsequent invasion of other cells. The success of infection, maintenance and survival inside host cells is facilitated by the ability of T. cruzi to subvert various host signaling mechanisms. We focus in this Review on the various mechanisms that induce host cytoskeletal rearrangements, activation of autophagy-related proteins and crosstalk among major immune response regulators, as well as recent studies on the JAK-STAT pathway.The protease 3C is encoded by all known picornaviruses, and the structural features related to its protease and RNA-binding activities are conserved; these contribute to the cleavage of viral polyproteins and the assembly of the viral RNA replication complex during virus replication. Furthermore, 3C performs functions in the host cell through its interaction with host proteins. For instance, 3C has been shown to selectively 'hijack' host factors involved in gene expression, promoting picornavirus replication, and to inactivate key factors in innate immunity signaling pathways, inhibiting the production of interferon and inflammatory cytokines. Importantly, 3C maintains virus infection by subtly subverting host cell death and modifying critical molecules in host organelles. This Review focuses on the molecular mechanisms through which 3C mediates physiological processes involved in virus-host interaction, thus highlighting the picornavirus-mediated pathogenesis caused by 3C.
