Behavioural support and nicotine replacement therapy for smokeless tobacco cessation in Bangladesh, India and Pakistan: A pilot randomized controlled trial.

BACKGROUND AND AIMS: Smokeless tobacco (ST) use in South Asia is high, yet interventions to support its cessation are lacking. We tested the feasibility of delivering interventions for ST cessation in South Asia. DESIGN: We used a 2 × 2 factorial design, pilot randomized controlled trial with a duration of 26 weeks, including baseline and follow-up (6, 12 and 26 weeks) assessments. SETTING: Two primary health-care facilities each in Dhaka (Bangladesh) and Karachi (Pakistan) and a walk-in cancer screening clinic in Noida (India) took part. PARTICIPANTS: Adult daily ST users willing to make a quit attempt within 30 days. Of 392 screened, 264 participants [mean age: 35 years, standard deviation = 12.5, 140 (53%) male] were recruited between December 2020 and December 2021; 132 from Bangladesh, 44 from India and 88 from Pakistan. INTERVENTIONS: Participants were randomized to one of three treatment options [8-week support through nicotine replacement therapy (NRT, n = 66), a behavioural intervention for smokeless tobacco cessation in adults (BISCA, n = 66) or their combination (n = 66)] or the control condition of very brief advice (VBA) to quit (n = 66). MEASUREMENTS: Recruitment and retention, data completeness and feasibility of intervention delivery were evaluated. Biochemically verified abstinence from tobacco, using salivary cotinine, was measured at 26 weeks. FINDINGS: Retention rates were 94.7% at 6 weeks, dropping to 89.4% at 26 weeks. Attendance in BISCA pre-quit (100%) and quit sessions (86.3%) was high, but lower in post-quit sessions (65.9%), with variability among countries. Adherence to NRT also varied (45.5% Bangladesh, 90% India). Data completion for key variables exceeded 93% among time-points, except at 26 weeks for questions on nicotine dependence (90%), urges (89%) and saliva samples (62.7%). Among follow-up time-points, self-reported abstinence was generally higher among participants receiving BISCA and/or NRT. At 26 weeks, biochemically verified abstinence was observed among 16 (12.1%) participants receiving BISCA and 13 (9.8%) participants receiving NRT. CONCLUSIONS: This multi-country pilot randomized controlled trial of tobacco cessation among adult smokeless tobacco users in South Asia demonstrated the ability to recruit and retain participants and report abstinence, suggesting that a future definitive smokeless tobacco cessation trial is viable.

Current status of pesticide effects on environment, human health and it's eco-friendly management as bioremediation: A comprehensive review.

Pesticides are either natural or chemically synthesized compounds that are used to control a variety of pests. These chemical compounds are used in a variety of sectors like food, forestry, agriculture and aquaculture. Pesticides shows their toxicity into the living systems. The World Health Organization (WHO) categorizes them based on their detrimental effects, emphasizing the relevance of public health. The usage can be minimized to a least level by using them sparingly with a complete grasp of their categorization, which is beneficial to both human health and the environment. In this review, we have discussed pesticides with respect to their global scenarios, such as worldwide distribution and environmental impacts. Major literature focused on potential uses of pesticides, classification according to their properties and toxicity and their adverse effect on natural system (soil and aquatic), water, plants (growth, metabolism, genotypic and phenotypic changes and impact on plants defense system), human health (genetic alteration, cancer, allergies, and asthma), and preserve food products. We have also described eco-friendly management strategies for pesticides as a green solution, including bacterial degradation, myco-remediation, phytoremediation, and microalgae-based bioremediation. The microbes, using catabolic enzymes for degradation of pesticides and clean-up from the environment. This review shows the importance of finding potent microbes, novel genes, and biotechnological applications for pesticide waste management to create a sustainable environment.

Smokeless tobacco quitting during COVID-19: A mixed-methods pilot study among participants screened for a cessation trial in India.

INTRODUCTION: COVID-19 and subsequent country-wide lockdown has impacted smokeless tobacco (SLT) product availability in India. We aimed to examine SLT quitting during COVID-19 lockdown among SLT users who consented to be enrolled in a cessation programme. METHODS: Between January-March 2020, we screened 227 exclusive SLT users to be enrolled in a randomized-controlled feasibility study on SLT cessation. However, all activities were suspended due to national lockdown in response to the COVID-19 pandemic. To examine the quitting intention and behaviour during COVID-19 lockdown, we re-contacted these individuals telephonically; during September-October 2020. RESULTS: Of 227 participants, 87 (38.3%) could not be contacted on phone. We conducted telephonic qualitative interviews and assessed the SLT use status, willingness to quit and participate in the SLT cessation trial among the remaining 140 participants. Among these, 12.1% (17/140) showed no willingness to participate in the study due to migration. Since COVID-19 lockdown, 32.1% (45/140) participants reported quitting SLT due to non-availability, increased cost of products, shifts in community norms and family pressures. CONCLUSIONS: COVID-19 pandemic presented an opportunity for tobacco cessation as stringent bans and isolation from social circles enabled tobacco cessation. It also triggered improvement in dissemination of public health information at an unprecedented scale, particularly related to the vulnerability of tobacco users to co-morbidities and harm from SARS CoV-2 infection. Implementation of strict bans on sale and consumption of SLT and strengthening of cessation support may lead to sustainable tobacco control. This study provides insight into effective policy strategies to reduce SLT use; which need to be substantiated with adequate cessation support.

Advanced Approaches Based on Expression of Different Genes and Biomarkers for the Diagnosis and Treatment of Renal Disorders.

This review focuses on the causes and complications of chronic kidney disease (CKD). The kidneys are major organs boasting various natural functions, chief among them the stable equilibrium of body fluids by eliminating waste. If the symptoms of CKD can be detected early, effective care is possible. CKD is a major area of investigation because it is the ninth most common cause of death in the United States. The incidence of kidney infection can be correlated with kidney malfunction. The main serological markers for renal disease are serum creatinine and creatinine clearance, which are insensitive and nonspecific to recognition of kidney injury. Standard therapy to prevent the progression of CKD includes dietary protein restriction, hypertension control, angiotensin converting enzyme inhibition (ACEi), and angiotensin receptor barricade (ARB). In this review we discuss advances in research on diagnostic biomarkers related to renal diseases and kidney-related injuries.
