Association between Serum Vitamin D Status and Circadian Syndrome: A Cross-Sectional Study.

BACKGROUND: Circadian Syndrome (CircS) encompasses cardiometabolic risk factors and comorbidities, indicating an elevated susceptibility to cardiovascular disease and type 2 diabetes. METHODS: This cross-sectional study aimed to investigate the association between vitamin D levels and each of the following: CircS, metabolic syndrome (MetS), and the individual components of CircS. Data from 14,907 adults who participated in the National Health and Nutrition Examination Survey (NHANES) between 2007 and 2018 were utilized. CircS was defined based on MetS components, alongside depression, short sleep, and non-alcoholic fatty liver disease (NAFLD). RESULTS: Our results indicated that low vitamin D levels exhibited meaningful associations with CircS, with vitamin D deficiency and inadequacy demonstrating 2.21-fold (95% CI 1.78-2.74, p < 0.001) and 1.33-fold (95% CI 1.14-1.54, p < 0.001) increases in CircS odds, respectively. The association between vitamin D deficiency and CircS was stronger than that with MetS. Additionally, a dose-response gradient in odds of CircS components, particularly with short sleep duration, was noted as serum vitamin D levels decreased. CONCLUSIONS: our findings highlight a significant association between low serum vitamin D levels and CircS and its components, particularly with short sleep. This suggests a potentially pivotal role of vitamin D in the pathogenesis of Circadian syndrome.

Perspectives of healthcare workers on integrated management of childhood illness in Pakistan: A phenomenological approach.

In 2019, an estimated 5.2 million deaths were reported among children less than 5 years of age. At primary healthcare level, healthcare workers (HCWs) mostly rely on history and clinical findings and less on inadequate diagnostic facilities. To enhance case management skills of HCWs, World Health Organization devised an integrated management of childhood illnesses (IMCI) strategy in 1995, modified to distance learning IMCI in 2014. A qualitative phenomenological study was conducted to explore perceptions of HCWs about standard and distance IMCI. Four focus group discussions were conducted with purposively selected 26 HCWs (IMCI trained) from 26 basic health units of Abbottabad district in Pakistan. Gadamer's philosophical hermeneutics were adopted during the inductive thematic analysis. Five themes that emerged are inexorable health seeking behaviors, IMCI being a comprehensive algorithm for consultation, a tedious protocol, scaling up protocol to specialists and private practitioners, and administrative insufficiency by the department of health. Improvement in case management skills of HCWs was reported as a result of IMCI trainings. It needs administrative support, regulations to control poly-pharmacy and provision of drugs without prescription, and a curb on political and bureaucratic interference.

Effectiveness of locally produced ready-to-use supplementary foods on the prevention of stunting in children aged 6-23 months: a community-based trial from Pakistan.

Undernutrition is a major public health problem in developing countries. Around 40·2 % of children are stunted in Pakistan. This longitudinal study aimed to assess the effectiveness of locally produced ready-to-use supplementary foods in the prevention of stunting by detecting change in of children in intervention v. control arm against the 2006 WHO growth reference. A community-based non-randomised cluster-controlled trial was conducted from January 2018 to December 2020 in the district of Kurram, Khyber Pakhtunkhwa, Pakistan. A total of 80 clusters (each cluster comprising ≈ 250-300 households) were defined in the catchment population of twelve health facilities. Children aged 6-18 months were recruited n 1680. The intervention included a daily ration of 50 g - locally produced ready-to-use-supplementary food (Wawa-Mum). The main outcome of this study was a change in length for age z-score (LAZ) v. WHO growth standards. Comparison between the interventions was by t test and ANOVA. Cox proportional hazard models were used to assess the association between stunting occurrence and the utilisation of locally produced supplement. Out of the total 1680, fifty-one out of the total 1680, 51·1 out of the total 1680 and 51·1 % (n 859) were male. Mean age 13·9 months (sd + 859) were male. Mean age 13·9 months (sd + -4·4). At baseline, 36·9 % (n 618) were stunted. In the intervention group, mean LAZ score significantly increased from -1·13(2·2 sd) at baseline to -0·93(1·8 sd) at 6-month follow-up (P value 0·01) compared with the control group. The incidence rate of stunting in the intervention arm was 1·3 v. 3·4 per person year in the control arm. The control group had a significantly increased likelihood of stunting (Hazard Ratio (HR) 1·7, 95 % CI 1·46, 2·05, P value < 0·001) v. the intervention group. Locally produced ready-to-use supplementary food is an effective intervention for reducing stunting in children below 2 years of age. This can be provided as part of a malnutrition prevention package to overcome the alarming rates of stunting in Pakistan.

Linkages between poverty and food insecurity in Pakistan: Evidence from urban and rural households in Peshawar.

Objective: To assess household poverty, sanitation and hygiene practices, and food security in both urban and rural settlements of district Peshawar. Methods: We conducted this cross-sectional study from March 2019 to October 2019 in the urban and rural households of Peshawar, KPK. Using stratified random sampling, 554 households (HH) having children and young adolescents of age 5-19 years, adult men > 19 - 62 years, and adult women >19 - 62 years were included in this study. Data was collected using comprehensive tool comprised of all validated questionnaires and was analyzed using SPSS Version 24.0. Result: Within the urban clusters, the maximum number of households (n=29) were from Gari Baloch and the minimum number of households (n=7) were from Gulberg. In the rural clusters, the maximum number of households surveyed (n=41) were from Lamara, minimum(n=21) was from Chargula. The average age of household heads was 44.5 ±12.5 with mean age slightly higher in urban areas (45.1 ±11.8) compared to 44.0 ±13.2 in rural areas. The mean poverty score was 56.8 (±11.6) with 72.1% non-poor households, and 94.2% households being food secure. Handwashing practices were highly prevalent among all the HH, however, handwashing practices before eating were comparatively lower in all HH (45.2%), lowest (37.8%) among rural households. Conclusion: The findings of the study revealed both non-poor and food secure households with satisfactory water, hygiene and sanitation practices.

Design and in silico analysis of mRNA vaccine construct against Salmonella.

Salmonella infections are continuously growing. Causative serovars have gained enhanced drug resistance and virulence. Current vaccines have fallen short of providing sufficient protection. mRNA vaccines have come up with huge success against SARS-CoV-2; Pfizer-BioNTech and Moderna vaccines have resulted in >90% efficacy with efficient translocation, expression, and presentation of antigen to the host immune system. Herein, based on the same approach a mRNA vaccine construct has been designed and analyzed against Salmonella by joining regions of genes of outer membrane proteins C and F of S. Typhi through a flexible linker. Construct was flanked by regulatory regions that have previously shown better expression and translocation of encoded protein. GC content of the construct was improved to attain structural and thermodynamic stability and smooth translation. Sites of strong binding miRNAs were removed through codon optimization. Protein encoded by this construct is structurally plausible, highly antigenic, non-allergen to humans, and does not cross-react to the human proteome. It is enriched in potent, highly antigenic, and conserved linear and conformational epitopes. Most conserved conformational epitopes of core protein lie on extended beta hairpins exposed to the cellular exterior. Stability and thermodynamic attributes of the final construct were found highly comparable to the Pfizer-BioNTech vaccine construct. Both contain a stable stem-loop structure downstream of the start codon and do not offer destabilizing secondary structures upstream of the start codon. Given structural and thermodynamic stability, effective immune response, and epitope composition the construct is expected to provide broad-spectrum protection against clinically important Salmonella serovars.Communicated by Ramaswamy H.

Non-Participatory Observation Of Integrated Management Of Childhood Illness Practices At Selected Basic Health Units Of District Abbottabad, Kp, Pakistan: A Qualitative Hermeneutic Study.

BACKGROUND: It was in 1995 when a strategy was devised to reduce under-five mortality in countries with a prevalence of child mortality above 40/1000 live births. This strategy is called "Integrated Management of Childhood Illness" (IMCI). Improvement in the skills of healthcare workers (HCWs) depends on the IMCI training received by them. To make IMCI training more effective and scale up, a global technical consultation committee in Geneva recommended implementing an innovative training approach in 2014: the distance learning IMCI (dIMCI). This study was conducted to observe qualitatively the practices of IMCI-trained HCWs at their respective workplaces. METHODS: This qualitative hermeneutic study was conducted through non-probability criterion sampling in the district Abbottabad of Pakistan on all 26 basic health units trained in IMCI (either standard or distance learning) from December 9, 2019, to March 9, 2020. Data collection was done by qualitatively observing consultations and interactions of caretakers of under-five children at basic health units. Inductive thematic analysis was used. This qualitative exploration was underpinned by Hans Georg Gadamer's philosophy of hermeneutics. RESULTS: Four themes emerged from the observation notes. These themes are gratification after consultation, altercation for medication, non-observance of protocol, and methodical consultation. CONCLUSIONS: Improvement in the skills of HCWs in the form of IMCI training, either through distance learning or the common eleven-day standard method, can improve caretakers' satisfaction. However, awareness at the community level is needed for better compliance.

Nanotubes Formation in P. aeruginosa.

The present study discusses a biofilm-positive P. aeruginosa isolate that survives at pH levels ranging from 4.0 to 9.0. The biofilm consortia were colonized with different phenotypes i.e., planktonic, slow-growing and metabolically inactive small colony variants (SCVs). The lower base of the consortia was occupied by SCVs. These cells were strongly attached to solid surfaces and interconnected through a network of nanotubes. Nanotubes were observed at the stationary phase of biofilm indwellers and were more prominent after applying weight to the consortia. The scanning electron micrographs indicated that the nanotubes are polar appendages with intraspecies connectivity. The micrographs indicated variations in physical dimensions (length, width, and height) and a considerable reduction in volume due to weight pressure. A total of 35 cells were randomly selected. The mean volume of cells before the application of weight was 0.288 µm3, which was reduced to 0.144 µm3 after the application of weight. It was observed that a single cell may produce as many as six nanotubes, connected simultaneously to six neighbouring cells in different directions. The in-depth analysis confirmed that these structures were the intra-species connecting tools as no free nanotubes were found. Furthermore, after the application of weight, cells incapable of producing nanotubes were wiped out and the surface was covered by nanotube producers. This suggests that the nanotubes give a selective advantage to the cells to resist harsh environmental conditions and weight pressure. After the removal of weight and proper supply of nutrients, these phenotypes reverted to normal planktonic lifestyles. It is concluded that the nanotubes are not merely the phenomenon of dying cells; rather they are a connectivity tool which helps connected cells to tolerate and resist environmental stress.

Biogenic Selenium Nanoparticles and Their Anticancer Effects Pertaining to Probiotic Bacteria-A Review.

Selenium nanoparticles (SeNPs) can be produced by biogenic, physical, and chemical processes. The physical and chemical processes have hazardous effects. However, biogenic synthesis (by microorganisms) is an eco-friendly and economical technique that is non-toxic to human and animal health. The mechanism for biogenic SeNPs from microorganisms is still not well understood. Over the past two decades, extensive research has been conducted on the nutritional and therapeutic applications of biogenic SeNPs. The research revealed that biogenic SeNPs are considered novel competitors in the pharmaceutical and food industries, as they have been shown to be virtually non-toxic when used in medical practice and as dietary supplements and release only trace amounts of Se ions when ingested. Various pathogenic and probiotic/nonpathogenic bacteria are used for the biogenic synthesis of SeNPs. However, in the case of biosynthesis by pathogenic bacteria, extraction and purification techniques are required for further useful applications of these biogenic SeNPs. This review focuses on the applications of SeNPs (derived from probiotic/nonpathogenic organisms) as promising anticancer agents. This review describes that SeNPs derived from probiotic/nonpathogenic organisms are considered safe for human consumption. These biogenic SeNPs reduce oxidative stress in the human body and have also been shown to be effective against breast, prostate, lung, liver, and colon cancers. This review provides helpful information on the safe use of biogenic SeNPs and their economic importance for dietary and therapeutic purposes, especially as anticancer agents.

Enhancing satisfaction and respect for health care personnel: a mixed-methods case study of a community-based intervention.

Health care personnel (HCP) face violence as a result of lack of satisfaction and respect among community members. It is imperative for HCP to engage in social work by involving communities for enhancing satisfaction and respect for them. This study attempted to provide insight on this phenomenon by using a mixed-methods concurrent embedded approach. Communities were selected based on modified Solomon four-group design from Karachi in southern province and from three cities of northern province, Khyber Pakhtunkhwa of Pakistan. Focus group discussions and in-depth interviews took place for formulating the quantitative tool. Six hundred pretests were done prior to introducing low-cost community-based interventions followed by 601 posttests. We found increased levels of satisfaction in both provinces, whereas level of respect increased significantly in Karachi in the southern province only. Qualitative interviews revealed the important role played by media and religious leaders. These findings suggest that satisfaction and respect for HCP can be enhanced through community support, involvement of religious leaders, and effective media campaigns.

Awareness, perceptions of and compliance with tobacco control policies among naswar vendors in Khyber Pakhtunkhwa Pakistan.

INTRODUCTION: Regulatory compliance in the retail environment is integral to the success of tobacco control. We assessed compliance among naswar (smokeless tobacco product widely used in South Asia) vendors with tobacco control laws. We also assessed their awareness of tobacco-related harms and policies and perceived effect of policies on their sales. METHODS: We surveyed 286 naswar vendors in three districts of the Khyber Pakhtunkhwa province of Pakistan. We recruited general and specialty vendors from urban and rural areas through multistage cluster sampling. Compliance was measured for promotion, sale to/by minors and tax paid on naswar. We used logistic regression analyses for assessing the association between the outcome variables (awareness of tobacco harms and laws, perceptions about the effect of policies on business and compliance with laws) and their predictors. RESULTS: Most vendors (70%) were aware of tobacco-related harms of naswar. Although educated vendors were more aware of tobacco control policies, the greatest awareness was for a ban on sales to/by minors (21% overall). The majority of vendors (76%) violated this policy (measured by self-report), and violations were more common among rural than urban vendors (OR 2.27, 95% CI 1.05 to 4.96). Most vendors (71%) violated a ban on promotion of naswar. Vendors perceived tax increases and sales ban to/by minors as most detrimental for business. CONCLUSIONS: There was poor awareness and compliance among naswar vendors in Pakistan with tobacco control laws. This study finds potential areas for policy interventions that can reduce urban/rural disparities in implementation of and compliance with tobacco control laws.

Breast Cancer Awareness and Associated Factors Amongst Women in Peshawar, Pakistan: A Cross-Sectional Study.

BACKGROUND: Breast cancer is the most common cancer in women, and the second overall, following lung cancer. Breast cancer can occur at any age, with an increased incidence in women 40 years and above. Worldwide the incidence is around 1 million cases per year, 60% of the cases reported from low- and middle-income countries. The current study was conducted to determine knowledge, attitude, and practices related to breast cancer, the associated risk factors, and screening methods in women presenting to a health care facility from resource-poor settings in Pakistan. METHODS: A cross-sectional study design was used, and participants were recruited phase-wise from three major outpatient departments (OPDs) (Gynecology and Obstetrics OPD, Medical OPD, and Surgical OPD). Data were collected through the validated "Breast Cancer Awareness Measure" developed by Cancer Research UK, King's College London, and University College London in 2009. Data were analyzed through Statistical Package for Social Sciences software (SPSS) version 23.0. Students's T-Test, ANOVA, and linear regression analysis were conducted. RESULTS: A total of 430 women were invited for participation in the study from the 3 main OPDs, and 400 took part in the study (response rate = 93.02%). The mean age of the women was 33.62 years ± 12.3 years, and the mean years of formal education were 5.05 ± 6.3 years. Less than a quarter of the participants were aware of the breast cancer warning signs, and 23.3% recognized the pain in the armpit or one of the breasts as a sign of breast cancer. The proportion of women aware of age-related and lifetime risk of getting breast cancer was 15.0%. Furthermore, only 2.5% performed breast self-examination at least once a month. Women identified many barriers like embarrassment, transport, and confidentiality issues in seeking medical help. CONCLUSION: Overall, women had poor knowledge of breast cancer, related warning signs, breast self-examination, risk factors, and screening methods.

Managing violence against healthcare personnel in the emergency settings of Pakistan: a mixed methods study.

OBJECTIVES: The primary objective of this study was to evaluate the effectiveness of a half-day training on de-escalation of violence against healthcare personnel regarding prevention and management of violence incidents versus a similar tertiary-level hospital with no such training. Secondary objectives were to compare the overall satisfaction, burnout, fear of violence and confidence in coping with patients' aggression of the healthcare personnel in the two hospitals. DESIGN: Mixed method design, with a comparative cross-sectional (quantitative) and focus group discussions (qualitative) components. SETTING: Emergency departments of the two tertiary care hospitals in district Peshawar over 6 months starting from May 2018. PARTICIPANTS: Healthcare personnel in the emergency departments of the two hospitals (trained vs untrained). OUTCOME MEASURES: Violence exposure (experienced/witnessed) assessed through a previously validated tool in the past 5 months. Burnout, confidence in coping with patient aggression and overall job satisfaction were also assessed through validated tools. The qualitative component explored the perceptions of healthcare personnel regarding the management of violence and the importance of training on de-escalation of violence through focus group discussions in the two hospitals. RESULTS: The demographic characteristics of the healthcare personnel within the two hospitals were quite similar. The de-escalation training did not lead to a reduction in the incidences of violence; however, confidence in coping with patient aggression and the overall satisfaction were significantly improved in the intervention hospital. The de-escalation training was lauded by the respondents as led to an improvement in communication skills, and the healthcare personnel suggested for scale-up to all the cadres and hospitals. CONCLUSION: The study found significant improvements in the confidence of healthcare personnel in coping with patient aggression, along with better job satisfaction and less burnout in the intervention hospital following the de-escalation training.

Supply Chain Actors' Willingness to Switch the Business of Smokeless Tobacco: A Mixed-Methods Study on Naswar Business in Pakistan.

INTRODUCTION: Provision of alternate livelihoods to smokeless tobacco (SLT) supply chain (SC) actors can help in curtailing SLT business and its consumption. We explored the reasons for SC actors' engagement in Naswar (SLT used in South Asia) business and their willingness to switch to other alternatives. AIMS AND METHODS: We conducted an equal-status concurrent mixed-methods study in four districts of Khyber Pakhtunkhwa province of Pakistan. We surveyed 286 general points of sale (GPOS) and exclusive Naswar (EN) vendors through multistage cluster sampling. Additionally, we interviewed 15 tobacco farmers interpretively, being distinct from other SC actors. We assessed the association between vendors' willingness to switch and their awareness about tobacco-harms, profit margin, Naswar as a family business, length of business, education level, and shop type using logistic regression. Qualitative data assessed the farmer's viable alternatives to switch and were analyzed using deductive-inductive thematic analysis. RESULTS: Product demand-77% and profit margins-75% were the main drivers for selling SLT by EN vendors. Half of the GPOS and 25% EN vendors expressed willingness to stop Naswar's sale. Vendors aware of tobacco-harms were more willing to switch, but less likely to switch if Naswar was perceived to bring "good profit." Farmers were mainly cultivating tobacco because of profitability, family-run farm, and perceived land-suitability for tobacco. Lack of government support was main constraint for farmers looking to switch. CONCLUSIONS: A considerable portion of Naswar SC actors in Pakistan are willing to switch to viable alternatives, with profitability of alternatives, support from authorities, and social obligations as key considerations in doing so. IMPLICATIONS: This study highlights that good profit margins in the Naswar business, lack of awareness of tobacco-related health harms, and absence of the government's support are key detriments to switching to alternative businesses among Naswar SC actors in Pakistan. These findings are the first to come out in the context of both Pakistan and Naswar product, making a case for policy interventions focusing on tax increases, awareness campaigns about tobacco-harms, and a proactive role by the government to provide support for the security of livelihoods to those tobacco SC actors who want to switch to other alternatives.

Prevalence and determinants of violence against health care in the metropolitan city of Peshawar: a cross sectional study.

BACKGROUND: Violence against healthcare personnel is a major public health problem. Healthcare personnel are at the frontline dealing with people in stressful and unpredictable situations. Therefore, this study was conducted to determine the prevalence and associated factors of violence against health care personnel. METHODS: A cross sectional study was conducted in the district Peshawar. Healthcare personnel from public and private sectors working in both the primary and tertiary levels of healthcare were invited to participate. Violence was assessed through a structured questionnaire previously used in Pakistan and was defined as experiencing and/or witnessing any form of violence in the last 12 months. Mental health was assessed through the General Health Questionnaire. Logistic regression was used to estimate the association of violence against healthcare personnel with psychological distress and demographic characteristics. Data entry and analysis were conducted in STATA 14. RESULTS: A total of 842 healthcare personnel participated in the study. The prevalence of violence experienced and/or witnessed by healthcare personnel in Peshawar was 51%. Verbal violence remained the predominant form of violence and almost half of the healthcare personnel (45%) were exposed to it. A quarter of the respondents (24%) reported physical violence alone or in combination with other forms of violence. In almost two third of the incidents the perpetrators were either attendants, relatives or the patients. The emergency unit and wards within healthcare facilities were the most common places where violent events took place. The major factors responsible for the violent incidents were communication failure, unreasonable expectations and perceived substandard care. No uniform policy/procedure existed to manage the incidents and the healthcare personnel adopted different responses in the wake of violent events targeting health care. Working in public healthcare facilities and having a larger number of co-workers/colleagues significantly increased the risk of violence in the healthcare settings while being a paramedic significantly reduced the risk as compared to physicians. CONCLUSIONS: Violence against healthcare personnel is a serious public health issue and the prevalence is quite high. A holistic effort is needed by all stakeholders including healthcare community, the administration, lawmakers, law enforcement, civil society, and international organizations.

Effectiveness Of DIMCI Training In District Abbottabad, Khyber Pakhtunkhwa: An External Pilot Study.

BACKGROUND: Five million deaths per year in under-five children are reported to be due to preventable and treatable causes. IMCI strategy targets these causes through improvement in the case management skills of health care workers. The objectives of this study were to identify eligible clusters and identify & rectify any process, resources, and management-related issues for the main trial. METHODS: This study was conducted in two phases. Phase 1 was conducted for eligibility of Basic Health Units from which sample can be drawn for the main cluster randomized control trial. A single-page proforma was sent to all 54 BHUs of Abbottabad through registered mail service and replies received were analysed through SPSS-V25 and MS Excel-2016. Afterward a sample of 26 BHUs was drawn for the definitive trial. In phase 2, four BHUs were conveniently selected from the remaining sampling frame; one in the control arm while three in the intervention arm. From each BHU, a health care worker responsible for under-five consultations was trained; control arm in standard IMCI while intervention arm on distance learning IMCI. Ten observations in the form of cases managed were assessed at each BHU by a gold standard IMCI master trainer after a specific period. Descriptive summary measures and 95% CI were calculated using SPSS-V25. RESULTS: Out of 54 BHUs, 3 were nonrespondents while 36 were identified as an eligible sampling frame. The mean index of integrated assessment was found to be 0.90 and 0.89 for the control and intervention arm respectively. Discrepancies in filled forms were noted as 60% in control while 63.3% in intervention arm. CONCLUSIONS: Modifications in the plan for the main trial based on the findings of pilot study can ensure credibility and rigor in the definitive trial.

Detection of Human Adenovirus, Rotavirus, and Enterovirus in Tap Water and Their Association with the Overall Quality of Water in Karachi, Pakistan.

Drinking water supplies in the developing world often serve as a biosphere for various organisms. Viral gastroenteritis is a neglected area of research in Pakistan, there are no data for the prevalence of enteric viruses in drinking water of the largest city of Karachi. The present study aimed to provide a survey of the existence of enteric viruses: human adenovirus (HAdV), human enteroviruses (hEV), and genotype A rotavirus (GARV) in tap water. Using a simple PCR approach, we detected 20%, 43%, and 23% of HAdV, hEV, and GARV in tap water samples, respectively. We have also shown an overall quality deficit of tap water at the pumping station and consumer tap. We have found no sample free from bacterial contaminations. The ranges for a total number of the heterotrophic plate count and coliform were found 8.7 × 102-4.5 × 106 CFU/mL and 210 to uncountable coliforms/100 mL, respectively. Moreover, we assessed the efficiency of small-scale water treatment methods for the removal of viruses.

Implementing smokeless tobacco control policy in Pakistan: a qualitative study among Naswar supply chain actors.

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.

An effective weapon against biofilm consortia and small colony variants of MRSA.

OBJECTIVES: This study was designed to investigate the effect of AgNPs (10 nm and 30 nm) on different phenotypes of Staphylococcus aureus biofilm consortia. MATERIALS AND METHODS: A total of eighteen biofilm-producing isolates of Methicillin-Resistant S. aureus (MRSA) were used in the present study. Tube methods, Congo-red agar method, and scanning electron microscopy (SEM) were used to study biofilm phenotypes. Population analysis assay on a tryptone soya agar (TSA) plate was applied to study the different phenotypes of biofilm consortia. The effect of AgNPs was evaluated by broth dilution assay. RESULTS: Results showed that biofilm consortia harbour different phenotypes, i.e., planktonic, metabolically inactive cells, and small colony variants (SCVs) or persister cells. The focus of the present study is the effect of AgNPs on biofilm consortia of MRSA, particularly on the SCVs population. Large size AgNPs (30 nm) were unable to diffuse through extracellular matrix material coverings of the biofilm consortia; they were only active against the planktonic population that occupies the outer surface of consortia. The smaller AgNPs (10 nm), on the other hand, were found to diffuse through the matrix material and hence were effective against planktonic as well as metabolically inactive population of consortia. Moreover, 30 nm AgNPs take 6 hr to disperse off and kill planktonic and upper surface indwellers. The 10 nm AgNPs disperse and kill the majority of biofilm indwellers within 20 min. CONCLUSION: The present study showed that 10 nm AgNPs can easily penetrate inside the biofilm and are active against all of the indwellers of consortia.

Compliance of Oral Snuff (Naswar) Packaging and Sales Practices with National Tobacco Control Laws and the Relevant Articles of Framework Convention on Tobacco Control in Khyber Pakhtunkhwa Pakistan.

INTRODUCTION: Smokeless tobacco (SLT) is a significant contributor to tobacco-related harm in Pakistan but its control has lags behind that of combustible tobacco. We assessed the compliance of Naswar's (a widely used SLT product in the Southeast Asia) packaging and sales practices with the national legislations and relevant articles of the WHO framework convention on tobacco control (FCTC). AIMS AND METHODS: A cross-sectional observational audit was conducted in three districts of Pakistan. We recruited 286 general point of sale (GPOS) and exclusive Naswar sellers (ENS) through a multistage cluster sampling strategy. Data were gathered on packaging and labeling practices of Naswar and advertisement and promotion practices inside and outside the shops. Statistical tests for association between the dependent variable-advertisement practices, and independent variables-area and vendor types were conducted. RESULTS: We analyzed 133 and 49 unique Naswar products sold in 229 GPOS and by 57 ENS, respectively. None of the local products had any written or pictorial health warning. More than half of retailers used one or two methods of advertising Naswar inside the shops while only 9% advertised outside the shops. ENS were more likely to be noncompliant with tobacco advertisement and promotion compared with GPOS. CONCLUSIONS: The study presents first insights on the compliance of Naswar packaging and sale practices with local regulations and WHO FCTC provisions in Pakistan. Almost all products were on display in the shops and none of the local products had any health warning or contents disclosure on the packages. IMPLICATIONS: Naswar is a form of SLT used extensively in Pakistan, Central Asia, and Pashtun populations across the globe. This study provides an important insight into the Naswar retail environment in a geographical setting where the use of Naswar is endemic. The study brings to fore previously unreported issues like an urban-rural disparity, and differences between exclusive and nonENS, with regards to Naswar advertisement and promotion. These findings have potential implication on the implementation of tobacco control retail policies. The lack of health warnings and free display of Naswar brands call for alignment of tobacco control efforts with the FCTC.

The magnitude and determinants of violence against healthcare workers in Pakistan.

Objectives: To determine the magnitude and determinants of violence against healthcare workers (HCWs) and to identify the predominant types and causes of violence experienced by them. Methodology: A cross-sectional survey based on structured questionnaire adopted from previous surveys and qualitative data was conducted in 4 large cities and 12 districts in 3 provinces of Pakistan. The survey covered 8579 from all cadres of HCWs, including doctors, nurses, technicians, support staff, ambulance workers, vaccinators, lady health visitors, midwives and lady health workers (LHWs). The predictors of overall violence experienced, physical violence experienced and verbal violence experienced were separately analysed for tertiary care hospitals, secondary care hospitals, primary care hospitals and field-level HCWs. Logistic regression was used to compute adjusted ORs with 95% CIs for the association of different factors with the violence experienced. Results: More than one-third (38.4%) reported having experienced any form of violence in the last 6 months. Verbal violence was the most commonly experienced form (33.9%), followed by physical violence (6.6%). The main reasons for physical violence were death of patients (17.6%), serious condition of patients (16.6%) and delay in care (13.4%). Among the different types of field HCWs, emergency vehicle operators were significantly more likely to experience verbal violence compared with LHWs (adjusted OR=1.97; 95% CI 1.31 to 2.94; p=0.001). Among hospital HCWs, those working in private hospitals were significantly less likely to experience physical violence (adjusted OR=0.52; 95% CI 0.38 to 0.71; p=0.001) and verbal violence (adjusted OR=0.57; 95% CI 0.48 to 0.68; p=0.001). Conclusion: Violence against HCWs exists in various forms among all cadres and at different levels of care. The gaps in capacity, resources and policies are evident. Specific strategies need to be adopted for different types of HCWs to protect them against violence.*The study was conducted under the framework of ICRC's Healthcare in Danger Initiative for protection of healthcare against Violence.
