Background And Objective: We evaluated the DR-TB component of the National Tuberculosis Elimination Program (NTEP) in a high-burden district in Kerala to identify the programmatic gaps, if any, in screening, diagnosis, treatment, and follow-up of notified DR-TB patients.

Methods: A mixed-methods design was used, and the evaluation was performed in two steps. In the first step, we reviewed the program documents and conducted stakeholder interviews to develop a detailed description of the program design and developed a logical framework to evaluate program performance.

Waste segregation at source, particularly at the household level, is an integral component of sustainable solid waste management, which is a critical public health issue. Although multiple interventions have been published, often with contradictory findings, few authors have conducted a comprehensive systematic synthesis of the published literature. Therefore, we undertook a systematic review to synthesize all published interventions conducted in any country in the world which targeted household-level waste segregation with or without additional focus on recycling or composting.

Context: After the gas tragedy on the night of December 2/3, 1984, at Bhopal, the Indian Council of Medical Research (ICMR) started following up on four population cohorts with different levels of post-disaster mortality from December 3-6, 1984.

Aims: The present study was undertaken to estimate the survival time of the cohort, and investigate the risk of mortality based on exposure, gender, and median age.

Settings And Design: Survival analysis is generally used to evaluate factors associated with the time to an event of failure or death among any covered population.

Introduction: Crowdsourcing is an emerging technique to engage or access a wider set of experts and multiple stakeholders through online platforms, which might effectively be employed in waste management. Therefore, we assessed the feasibility of the crowdsourcing method to provide an alternative approach that can improve household waste segregation using an "online-slogan-contest".

Methods: The contest was promoted via targeted emails to various governmental and non-governmental organizations and through social media platforms for around 4 weeks (25 days).

Waste segregation is an essential function in improving waste management. Waste segregation not only facilitates recycling and reduces waste going to landfills, rather it can benefit our environment and human in various ways. A pick analysis of waste composition is used to characterize the household waste stream and thus can analyze the segregation rate among the residents.

Background The survivors of the 1984 Bhopal gas disaster frequently express concern of them being at higher risk of developing chronic kidney disease (CKD) as a consequence of the long-term health effects of gas exposure. We aimed to estimate the prevalence of CKD among the survivors of severely gas-exposed cohort assembled in 1985 after the Bhopal gas disaster to study the long-term health consequences of gas exposure. Methods We did this cross-sectional study with a sample size of 215 systematically selected participants among the severely gas-exposed survivors in Bhopal to estimate the prevalence of CKD.

Article Synopsis
  • A differentiated care strategy can effectively triage high-risk TB patients for comprehensive assessment and inpatient care, potentially reducing deaths in resource-limited settings.
  • In Tamil Nadu, India, a strategy known as TN-KET was rolled out in April 2022, which saw 78% of notified TB patients triaged, with notable outcomes for those assessed as severely ill.
  • The analysis identified factors influencing care retention and admission outcomes, highlighting areas for improvement, such as addressing predictors of loss in the care cascade and increasing the duration of patient admissions.

Due to the workload and lack of a critical mass of trained operational researchers within their ranks, health systems and programmes may not be able to dedicate sufficient time to conducting operational research (OR). Hence, they may need the technical support of operational researchers from research/academic organisations. Additionally, there is a knowledge gap regarding implementing differentiated tuberculosis (TB) care in programme settings.

Introduction: The ongoing Coronavirus disease 2019 (COVID-19) pandemic has had a huge mental health impact on people, especially the infected population. They are at greater risk of developing psychological symptoms due to the fear of death and developing severe disability, lack of proper treatment and social restrictions, stigma, and discrimination. The early psychological symptoms, if ignored, may have long-term consequences on the health and well-being of COVID patients.

Increasing generation of wastewater and its indiscriminate disposal is detrimental to human and animal health. Resource-limited settings often struggle for efficient wastewater treatment systems owing to lack of funds and operational difficulties. Therefore, alternative treatment systems involving low expenditure and simplistic operations are need of the hour.

Microplastics are the newly emerged contaminants with a presence in almost every part of the globe. Despite being small in size, microplastic particles have proved to be harmful for plants, animals, humans, and for the ecosystem in general. Water is one of the most important routes through which microplastics transfer from one place to another.

Background: Segregation of household waste at the source is an effective and sustainable strategy for management of municipal waste. However, household segregation levels remain insufficient as waste management approaches are mostly top down and lack local support. The realisation and recognition of effective, improved and adequate waste management may be one of the vital drivers for attaining environmental protection and improved health and well-being.

Background & Objective: Pirimiphos-methyl, an organophosphorus insecticide is known to overcome resistance mechanisms of mosquitoes to other organophosphates. Information on the duration of efficacy of pirimiphos-methyl (50% emulsifiable concentrate) for the control of immatures of Culex quinquefasciatus, the vector of bancroftian filariasis, is scanty and hence site specific field trials are necessary to determine the field dosage. Pirimiphos-methyl (50% EC) was tested for its efficacy in cesspits and drains against the immatures of Cx.
