This paper attempts to address the intersections of gender, caste, class, sexuality, region, and other social attributes, that constitute the social web in India influencing the possibilities and exclusions within sport. Being at the margins of this social web makes individuals vulnerable to unethical practices such as discrimination, exclusion, and erasures of their lived realities, by both systemic and everyday practices. Using the lens of social reproduction the paper attempts to capture not just the productive work that sustains a sporting milieu in society, but the labour that produces leisure, entertainment, play, rest, fitness, pleasure, well-being, and care that sustains and is further generated by families, communities and entire societies.

Background: In proximal hypospadias, ventral curvature is invariable and most have penoscrotal transposition, and we observed that the base of the penis (BOP) was located on the inferior aspect of the pubic bones in those, in contrast to the location of the BOP at the anterior end in normal penises. We also observed an unfused bulbospongiosus muscle (BSM) at surgery in those. The aim was to assess the impact of repairing the unfused BSM or transection and straightening of the urethral plate at the first operation on the low BOP.

Non-standard amino acids (nsAAs) that are L-phenylalanine derivatives with aryl ring functionalization have long been harnessed in natural product synthesis, therapeutic peptide synthesis, and diverse applications of genetic code expansion. Yet, to date these chiral molecules have often been the products of poorly enantioselective and environmentally harsh organic synthesis routes. Here, we reveal the broad specificity of multiple natural pyridoxal 5'-phosphate (PLP)-dependent enzymes, specifically an L-threonine transaldolase, a phenylserine dehydratase, and an aminotransferase, towards substrates that contain aryl side chains with diverse substitutions.

Article Synopsis
  • The study compares two surgical techniques for treating unstable distal radius fractures: percutaneous fixation using Kirschner wires and open reduction with volar locking plates.
  • A systematic review of 14 randomized controlled trials involving 2,226 patients showed that the plating group had better functional outcomes (measured by DASH scores) especially at one-year follow-up, while both techniques had similar radiological results and complication rates.
  • The authors emphasize caution in interpreting these results due to variability in the trials and highlight the need for more high-quality studies to establish definitive conclusions across different patient demographics and fracture types.

Context: Despite the Weekly Iron folic acid supplementation (WIFS) program, the prevalence of anaemia among adolescent girls remains high. Phase 1 Indian Council of Medical Research (ICMR) task force study conducted in 2016 in Kallur showed that the IFA provision rate for adolescent girls was 72% but the consumption rate was only 15% in the Kallur area. The present study was done to identify the gaps for the difference between provision and consumption rate of weekly IFA tablets among adolescent girls using the WHO conceptual framework in home-based settings.

Introduction: Diuretic renography is crucial in evaluation of paediatric hydronephrosis. Furosemide is conventionally given 15-20 min after radiolabelled tracer (F+15/F+20 protocol), however this is equivocal in around 15% of patients. Giving furosemide 15 min prior to tracer (F-15 MAG3 protocol) has been suggested as an additional tool in the investigation of patients with suspected upper urinary tract obstruction.

Article Synopsis
  • The study compares the outcomes of transcarotid artery revascularization (TCAR) and transfemoral carotid artery stenting (tfCAS) over a 3-year period, finding TCAR has significantly lower mortality rates, especially in the first 6 months.
  • It analyzed data from over 70,000 patients and adjusted for various demographic and clinical factors, revealing that TCAR patients had higher comorbidities and were older.
  • The results indicate that TCAR is associated with a 24% reduction in mortality hazard compared to tfCAS, suggesting it may be the better option for patients needing carotid artery interventions.

Polymeric materials are ubiquitous to modern life. However, reliance of petroleum for polymeric building blocks is not sustainable. The synthesis of macromolecules from recalcitrant polymer waste feedstocks, such as plastic waste and lignocellulosic biomass, presents an opportunity to bypass the use of petroleum-based feedstocks.

Introduction: Paediatric urologists manage a spectrum of conditions, much of the evidence for relevant treatment pathways is of low quality. For many conditions treatment varies according to location and surgeon; children with the same condition might have surgery in one unit but watchful waiting in another. Underlying this variation are differences in opinion, and insufficient high-level evidence with few prospective randomized studies.

Introduction: Acute epididymo-orchitis (AEO) is becoming an increasingly common differential diagnosis in children with acute scrotal pain. It has been noted in adult men that SARS-CoV-2 has a propensity for involving the testis and epididymis, affecting sperm and testosterone production. Our literature search revealed only one case report of COVID-19 presenting with epididymo-orchitis in a child.

Background: The National Family Health Survey of India (NFHS-5) revealed a lapse in the advancement of mitigating anemia despite free supplementation of iron-folic acid tablets (IFAT) and improvement in IFAT coverage during pregnancy. The local sociocultural beliefs and community perspective toward IFAT are pivotal in reducing the gap between IFAT coverage and consumption. Hence, we proposed the study to assess adherence to IFAT among rural pregnant women and explore the associated factors.

Background: In single-ventricle patients undergoing staged-bidirectional Glenn, 36-59% have aorto-pulmonary collateral flow, but risk factors and clinical outcomes are unknown. We hypothesise that shunt type and catheter haemodynamics may predict pre-bidirectional Glenn aorto-pulmonary collateral burden, which may predict death/transplantation, pulmonary artery or aorto-pulmonary collateral intervention.

Methods: Retrospective cohort study of patients undergoing a Norwood procedure for single-ventricle anatomy.
