Oral cancer is second most common cancer in Pakistan and one of the major contributing factors to its high incidence is smokeless tobacco (SLT) use. 5.3% of Pakistan's youth are current SLT users. The World Health Organization requires the signatories of its "Framework Convention on Tobacco Control" to officially ban the sale of tobacco products to minors. We reviewed the Government of Pakistan's tobacco control, and related supporting policies, to assess how these address the issue of sale of SLT products to minors and found evident gaps in this regard. Legislations need to be in place to ban the sale of SLT products to minors and avoid an SLT epidemic in the future.

Abstract Oral cancer is second most common cancer in Pakistan and one of the major contributing factors to its high incidence is smokeless tobacco (SLT) use. 5.3% of Pakistan's youth are current SLT users. The World Health Organization requires the signatories of its "Framework Convention on Tobacco Control" to officially ban the sale of tobacco products to minors. We reviewed the Government of Pakistan's tobacco control, and related supporting policies, to assess how these address the issue of sale of SLT products to minors and found evident gaps in this regard. Legislations need to be in place to ban the sale of SLT products to minors and avoid an SLT epidemic in the future.

This study looked at the comprehensiveness of the primary health care approach being applied in Pakistan's National Maternal, Newborn and Child Health (MNCH) Programme launched in 2005. The methods included a review of the programme's guideline documents, in-depth interviews with managers/advisors and focus group discussions with community groups and service providers. The MNCH Programme is applying a selective primary care model. Programme advisors and managers were concerned about the quality of training, political interference and incomplete implementation. Service providers were not working together as envisioned. Community midwives complained about the community's perceptions of them. Community members were unaware of MNCH Programme implementation in their areas. Pakistan's primary health care programme needs to be reviewed and revised according current thinking on community participation and inter-sectoral collaboration to accelerate progress towards achievement of Millennium Development Goals 4 and 5.

Background Public attitude is a political driver in successful implementation of tobacco control policies. We assessed support for a range of tobacco control policies among smokers in Pakistan. Methods We conducted a household survey among adult smokers in 10 cities of Pakistan, using a two-stage random sampling strategy to select households and Kish grid method to select one smoker per household. Attitudes were measured using a five-point ordinal scale on four policy statements: a complete ban on tobacco sale within 10 years; raising the legal age to buy tobacco from 18 to 21; increasing tobacco taxes to fund healthcare and a ban on smoking in cars with minors. Results 6014 participants were interviewed between September 2019 and March 2020. Most participants demonstrated strong support for all policy statements: a ban on smoking in cars with minors (86.5%); a complete ban on tobacco sale within 10 years (82.1%); raising the legal age to buy tobacco (77.9%) and increasing tobacco taxes (68.1%). Smokers' support for tobacco control policies increased with age but decreased with higher educational attainment and heaviness of smoking. Conclusions There is strong support among smokers in Pakistan to strengthen tobacco control. Given this, policy-makers should strongly consider strengthening existing national policies on tobacco control.

The majority of crops cultivated in tropical and subtropical regions across the world face significant risks due to climate change. Drought is one of the most critical environmental factors that might reduce agricultural productivity and yield. When crops are subjected to drought stress, they exhibit a variety of reactions on several levels, including the morphological, physiological, biochemical, and molecular levels. Polygenes regulate a sophisticated trait, drought tolerance, and a wide variety of environmental factors modulate the expression of these polygenes. In addition, drought stress affects plant protein changes, hormone composition, root depth and extension, osmotic adjustment, antioxidant generation, opening and closing of stomata, cuticle thickness, inhibition of photosynthesis, decreased transpiration, and growth may affect inhibition and chlorophyll content. In addition to various osmotic changes in their organs. Plants respond to drought by activating defense mechanisms, which cause a decrease in grain yield, changes in photosynthetic parameters, and an increase in specialized metabolic chemicals. This review article investigates water restriction and its effects on wheat's morphological, physiological, biochemical, and molecular responses concerning potential damage caused by drought stress.

OBJECTIVE: To obtain insights into the perceptions of barriers and facilitators to implementation of the WHO Framework Convention on Tobacco Control (FCTC) among smokeless tobacco (SLT) supply chain actors in the Khyber Pakhtunkhwa province of Pakistan. METHODS: We conducted a qualitative study to investigate the perceptions about SLT control policy formulation and implementation among exclusive Naswar sellers and point of sale vendors. We conducted five focus group discussions in three districts of Khyber Pakhtunkhwa using combined deductive-inductive thematic analyses. RESULTS: We identified three central themes that potentially impact policy formulation, its implementation and application. The first theme examines the role of children in the Naswar business: as potential customers, and as potential heirs to a Naswar-selling business. A second theme targets the 'business of Naswar', which includes a specific identity of Naswar sellers, its potential to generate profits and the special case of Naswar regulation as a socially accepted and culturally rooted product. The third theme addresses the unusual ingredients of Naswar and its production process, making Naswar a health risk for consumers and producers. We also report conflicting views regarding SLT control among the supply chain actors. CONCLUSIONS: This study provides insights into the perceptions of important SLT supply-side stakeholders regarding various SLT control policy options based on the FCTC. While there is some opposition to policy approaches like taxation and switching of business, implementing a ban on selling SLT to minors may be a viable option for policymakers in the short term.

Introduction: South Asia is home to more than 300 million smokeless tobacco (ST) users. Bangladesh, India and Pakistan as signatories to the Framework Convention for Tobacco Control (FCTC) have developed policies aimed at curbing the use of tobacco. The objective of this study is to assess the compliance of ST point-of-sale (POS) vendors and the supply chain with the articles of the FCTC and specifically with national tobacco control laws. We also aim to assess disparities in compliance with tobacco control laws between ST and smoked tobacco products.Methods and analysis: The study will be carried out at two sites each in Bangladesh, India and Pakistan. We will conduct a sequential mixed-methods study with five components: (1) mapping of ST POS, (2) analyses of ST samples packaging, (3) observation, (4) survey interviews of POS and (5) in-depth interviews with wholesale dealers/suppliers/manufacturers of ST. We aim to conduct at least 300 POS survey interviews and observations, and 6-10 in-depth interviews in each of the three countries. Data collection will be done by trained data collectors. The main statistical analysis will report the frequencies and proportions of shops that comply with the FCTC and local tobacco control policies, and provide a 95% CI of these estimates. The qualitative in-depth interview data will be analysed using the framework approach. The findings will be connected, each component informing the focus and/or design of the next component.Ethics and dissemination: Ethical approvals for the study have been received from the Health Sciences Research Governance Committee at the University of York, UK. In-country approvals were taken from the National Bioethics Committee in Pakistan, the Bangladesh Medical Research Council and the Indian Medical Research Council. Our results will be disseminated via scientific conferences, peer-reviewed research publications and press releases.

Introduction: We assessed the magnitude of smokeless tobacco (ST) use in Pakistan and identified policy gaps to help ascertain short-, medium-, and long-term priorities. We then elicited stakeholders' views as to which of these identified priorities are most important.Methods: In a multimethod study, we: analyzed Global Tobacco Surveillance System data sets to estimate ST consumption and disease burden; conducted a documentary review to identify gaps in policies to control ST in comparison with smoking; elicited stakeholders' views in an interactive workshop to identify a set of policy options available to address ST burden in Pakistan; and ranked policy priorities using a postevent survey.Results: Among all tobacco users in Pakistan (n = 24 million), one-third of men and two-thirds of women consume ST. In 2017, its use led to an estimated 18 711 deaths due to cancer and ischemic heart disease. Compared to smoking, policies to control ST lag behind significantly. Priority areas for ST policies included: banning ST sale to and by minors, advocacy campaigns, introduction of licensing, levying taxes on ST, and standardizing ST packaging. A clear commitment to close cooperation between state actors and stakeholder groups is needed to create a climate of support and information for effective policy making.Conclusion: Smokeless tobacco control in Pakistan should focus on four key policy instruments: legislation, education, fiscal policies, and quit support. More research into the effectiveness of such policies is also needed.Implication: A number of opportunities to improve ST regulation in Pakistan were identified. Among these, immediate priorities include banning ST sale to and by minors, mobilizing advocacy campaign, introduction of licensing through the 1958 Tobacco Vendors Act, levying taxes on ST, and standardizing ST packaging.

INTRODUCTION: Smokeless tobacco (ST) was consumed by 356 million people globally in 2017. Recent evidence shows that ST consumption is responsible for an estimated 652 494 all-cause deaths across the globe annually. The WHO Framework Convention on Tobacco Control (FCTC) was negotiated in 2003 and ratified in 2005 to implement effective tobacco control measures. While the policy measures enacted through various tobacco control laws have been effective in reducing the incidence and prevalence of smoking, the impact of ST-related policies (within WHO FCTC and beyond) on ST use is under-researched and not collated. METHODS AND ANALYSIS: A systematic review will be conducted to collate all available ST-related policies implemented across various countries and assess their impact on ST use. The following databases will be searched: Medline, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Scopus, EconLit, ISI Web of Science, Cochrane Library (CENTRAL), African Index Medicus, LILACS, Scientific Electronic Library Online, Index Medicus for the Eastern Mediterranean Region, Index Medicus for South-East Asia Region, Western Pacific Region Index Medicus and WHO Library Database, as well as Google search engine and country-specific government websites. All ST-related policy documents (FCTC and non-FCTC) will be included. Results will be limited to literature published since 2005 in English and regional languages (Bengali, Hindi and Urdu). Two reviewers will independently employ two-stage screening to determine inclusion. The Effective Public Health Practice Project's 'Quality Assessment Tool for Quantitative Studies' will be used to record ratings of quality and risk of bias among studies selected for inclusion. Data will be extracted using a standardised form. Meta-analysis and narrative synthesis will be used. ETHICS AND DISSEMINATION: Permission for ethics exemption of the review was obtained from the Centre for Chronic Disease Control's Institutional Ethics Committee, India (CCDC_IEC_06_2020; dated 16 April 2020). The results will be disseminated through publications in a peer-reviewed journal and will be presented in national and international conferences. PROSPERO registration number CRD42020191946.
