Background: India, one of the largest consumers of tobacco, has seen a dramatic rise in tobacco-attributable deaths over the past three decades. Among proven tobacco control strategies, Pictorial Health Warning Labels (PHWL) are effective and cost-efficient, especially in countries with lower literacy rates. Despite global guidelines under the WHO FCTC and India's own COTPA legislation, implementation of PHWL has faced sustained resistance from the tobacco industry (TI).

Shape Memory Alloys (SMAs) are pivotal in diverse industrial applications due to their exceptional properties, including actuation, biocompatibility, and adaptability in aerospace, biomedical, and military domains. However, their complex machinability often leads to high costs and suboptimal surface quality when processed using traditional methods. Using Response Surface Methodology (RSM) with a Central Composite Design (CCD), this study evaluated the effects of input parameters, including pulse on time (T), pulse off time (T), peak current (Ip), and gap voltage (GV), on material wear responses during Electrical Discharge Machining (EDM).

Non-small cell lung cancer (NSCLC) is the most common subtype constituting around 85 % of all lung cancer cases. Based on the cancer stage, surgery, radiotherapy, chemotherapy, immunotherapy and molecularly targeted therapy are the main treatment options for NSCLC. In last two decades, significant advancements in the treatment of NSCLC have been achieved through the development of molecular targeted therapies and immunotherapies.

Background: Although metabolic and bariatric surgery (MBS) is a safe and effective procedure to reduce severe obesity and is covered by most health insurance plans, utilization of MBS is significantly lower among men compared to women. This study identifies unique factors that explain men's attitude towards MBS.

Methods: The study survey (paper/online) included 129 Black and White men with severe obesity from metropolitan communities in Western New York.

Purpose: The purpose of this study was to validate experimentally measured beam data, and treatment planning system (TPS) calculated volumetric modulated arc therapy (VMAT) three-dimensional (3D) dose distribution using PRIMO Monte Carlo (MC) simulation and one-dimensional (1D) gamma index analysis.

Materials And Methods: The PRIMO code simulates the percentage depth dose (PDD) and beam profiles across varying field sizes in water phantoms, which were then compared with the ion chamber-measured beam characteristics using 1D gamma analysis. For the VMAT 3D dose distribution, the computed tomography scan of the anthropomorphic pelvis phantom was used for dose calculation and simulation in Eclipse TPS and PRIMO, respectively.

Several recent literature reports indicate the strong neuroprotective potential of synthetic heterosteroids, still search for potent, safer and effective neuroprotective steroidal molecules continues. In the current study, a new series of 17-oximino-16-substituted steroids (1-8) has been evaluated in MPTP-induced Parkinson's disease in mice and amyloid-β induced Alzheimer's disease in rats with an intention to discover an effective and efficient neuroprotective molecule. Behavioural studies followed by histopathological and estimation of the several neuroinflammatory biochemical parameters such as acetylcholinesterase, lipid peroxide, reactive oxygen, and nitric oxide species were carried out.

Global levels of critical food insecurity continue to rise as the projected population is expected to reach approximately 10 billion in 2050. Meeting the growing demands for food protein, improved nutritional quality, and environmental sustainability requires transitioning from animal-sourced products. Plant-based products have emerged as the most prominent and major alternative solution toward improving the current food production system; however, plant-based products come with their flaws.

Introduction: The key for public health programs to succeed is their successful implementation to achieve the desired outcomes. For integrating legislative measures such as the Cigarette and Other Tobacco Products Act (COTPA), which needs a component of enforcement, unless there is optimal engagement and empowerment of the assigned agencies, the outcomes are likely to be weak and incomplete at best.

Current Status: Enforcement of COTPA under the National Tobacco Control Programme (NTCP) has succeeded only partly despite the best efforts of State Tobacco Control Cells (STCCs) countrywide.

Article Synopsis
  • Deprescribing is essential for older adults, focusing on safe medication management, and effective communication is critical in this process.
  • An international group of 14 experts created a framework to analyze how communication is utilized in deprescribing, identifying the need for more comprehensive approaches beyond just clinician-patient interactions.
  • The research highlights missed opportunities for enhancing deprescribing communication at the community level and calls for further studies to determine the most effective communication strategies and styles for this process.

Article Synopsis
  • Traumatic brain injury (TBI) is a significant health issue, particularly in low- and middle-income countries like India, which presents different epidemiological trends and care practices compared to Europe.
  • Data from studies in India (CINTER-TBI) and Europe (CENTER-TBI) reveal that patients in India tend to be younger and more severely injured than those in Europe, with falls being the main cause in Europe and traffic incidents in India.
  • Access to pre-hospital care is markedly higher in Europe, with Indian patients more likely to receive certain surgical interventions for severe TBI, indicating differences in acute care responsiveness between the regions.

This article discusses examples from an extended family of aphorisms, stories, and themes that have circulated widely in STS and remain associated with the formation and integration of the field. Drawing upon Harvey Sacks's insightful remarks about features of everyday conversation, which he related to ancient practices in oral culture, we argue that familiar citation magnets in STS operate in many respects like proverbs, parables, and an extended family of neatly and memorably packaged viral articulations in ordinary language. After discussing the contingent production of proverbial truth, the article focuses on three well-known examples that combine memorable proverbs and themes with parables: Winner's account of the low parkway bridges designed by city planner Robert Moses to show that technology politics; Pinch and Bijker's concise history of the bicycle to illustrate the social construction of technology, and Star and Griesemer's viral two-word theme of 'boundary objects' as artifacts that sustain collaboration across organizational contexts.

Introduction: In patients with anterior circulation aneurysmal Subarachnoid Haemorrhage (aSAH), endovascular coiling is currently practiced more frequently than neurosurgical clipping. However, despite multiple previous studies, it is still uncertain whether coiling is favourable in terms of long-term clinical outcome.

Research Question: What is the effect of clipping versus coiling on long-term functional outcome of patients with an aSAH?

Material And Methods: All anterior circulation aSAH patients (2012-2015) treated with clipping or coiling in two hospitals in the Netherlands were studied up to five years after treatment.

Vascular compression syndromes are a diverse group of pathologies that can manifest asymptomatically and incidentally in otherwise healthy individuals or symptomatically with a spectrum of presentations. Due to their relative rarity, these syndromes are often poorly understood and overlooked. Early identification of these syndromes can have a significant impact on subsequent clinical management.
