Barriers to childhood vaccination in urban slums of Pakistan.

Background: The urban slums of Pakistan continue to record low childhood vaccination coverage. It is therefore vital to understand the demand-side barriers to childhood vaccination in the slums to determine the required demand-generation interventions. Aims: To document the demand-side barriers related to childhood vaccination in urban slums of Pakistan and recommend appropriate demand-generation interventions. Methods: We investigated the demand-side barriers to childhood vaccination in 4 urban slums of Karachi, Pakistan, and disseminated the findings to the Expanded Program on Immunization and their partners. Using the findings, we made recommendations for collaborations with the various partners and for the design of demand-generation interventions to address the barriers. We then expanded the scope of the original research through a mapping exercise that gathered information on the vaccination-related research and interventions of the partners and used the information gathered to create a portfolio of activities. We present the demand-side barriers from the original research and the portfolio of demand-generation interventions. Results: The original research showed that 412 (49.0%) children aged 12-23 months, from 840 households, were fully vaccinated. Reasons given for not receiving the recommended vaccinations were mainly related to the fear of side effects, social and religious influences, lack of awareness, and misconceptions about vaccine administration. The mapping of activities revealed 47 initiatives that aimed to generate demand for childhood vaccination in the urban slums of Pakistan. Conclusion: Several stakeholders involved in childhood vaccination in the urban slums of Pakistan act independently, operating programmes that are disconnected. There is a need for better coordination and integration of the childhood vaccination interventions by these partners to achieve the goal of universal vaccination coverage.

Gutka consumption and dietary partialities explaining anemia in women of a coastal slum of Karachi, Pakistan: A mixed-method study.

BACKGROUND: Limited literature is available on the dietary pattern and its consequences on health of women living in coastal slums of Karachi, Pakistan. MATERIAL AND METHODS: The study employed a mixed-method approach where concurrent quantitative and qualitative assessments were carried out. An analytical cross-sectional survey was conducted to collect information on demographic, household, obstetrics characteristics, and dietary pattern of married women of reproductive age (MWRA). Blood samples were collected to identify the hemoglobin level to determine anemia. For the qualitative component, focus group discussions were carried out with women and in-depth interviews with shopkeepers to understand the availability of food items at household level and in local markets respectively. In addition, observational visits were carried out at different points in time to the local market to document the availability of iron-rich foods for the community. RESULTS: The overall prevalence of anemia in sample population was 68.0%. Women with no formal education (AOR: 2.93 95% CI: 1.90-4.52), who consumed gutka (AOR: 2.84 95% CI: 1.81-4.46), did not eat red meat (AOR: 1.68 95% CI: 1.06-2.65), and only had seafood (AOR: 4.56 95% CI: 1.38-15.02) were more likely to be anemic as compared to their counterparts. Qualitative data revealed that any kind of meat and fruits were beyond the reach of community people due to non-affordable cost. A high percentage of women used a locally produced recreational substance known as gutka which gives them a feeling of wellbeing and suppresses hunger. CONCLUSION: In our study population, lack of access to diversity of food items, illiteracy, and use of gutka are the statistically significant factors which are associated with anemia in married women of this coastal slum area. The lack of demand for diversity in food is related to poverty and preference of spending money on gutka.

Meta-analysis of incidence and outcomes of life-threatening arrhythmias in takotsubo cardiomyopathy.

BACKGROUND: Takotsubo cardiomyopathy (TC) or stress-induced cardiomyopathy is a transient heart condition that clinically resembles an acute coronary syndrome. This study aims to assess the incidence of life-threatening arrhythmias in patients with Takotsubo cardiomyopathy and evaluate the outcomes of patients with life-threatening arrhythmias (LTAs) in Takotsubo cardiomyopathy compared with those without LTA. METHODS: We comprehensively searched the PubMed, Google Scholar, and Embase databases from inception to February 2021. The primary aim of the study was to determine the incidence of LTAs in TC patients. Other outcomes of interest were the odds of in-hospital, long-term mortality, and cardiogenic shock (CS) in TC patients with LTAs versus those without LTAs. For all statistical analyses, ReviewManager and MedCalc were used. RESULTS: Eighteen studies were included in this study involving 55,557 participants (2,185 with LTAs and 53,372 without LTAs). The pooled incidence of LTAs in the patients of TC was found to be 6.29% (CI: 4.70-8.08%; I2 = 94.67%). There was a statistically significant increased risk of in-hospital mortality (OR = 4.74; CI: 2.24-10.04; I2 = 77%, p < 0.0001) and cardiogenic shock (OR = 5.60; CI: 3.51-8.95; I2 = 0%, p < 0.00001) in the LTA group versus the non-LTA group. LTA was not associated with long-term mortality (OR = 2.23; CI: 0.94-5.28; I2 = 53%, p = 0.07). CONCLUSION: The pooled incidence of life-threatening arrhythmias in the patients of TC was found to be 6.29%. In the group of TC patients with LTAs, the odds of in-hospital mortality and CS, was higher than in the TC patients without LTAs.

Role of gene therapy in Fanconi anemia: A systematic and literature review with future directions.

Gene therapy (GT) has been reported to improve bone marrow function in individuals with Fanconi anemia (FA); however, its clinical application is still in the initial stages. We conducted this systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, to assess the long-term safety and clinical outcomes of GT in FA patients. Electronic searches from PubMed, Web of Science, Cochrane Library, and Google Scholar were conducted and full texts of articles meeting our inclusion criteria were reviewed. Three clinical trials were included, with a total of nine patients and mean age of 10.7 ±â€¯5.7 years. All patients had lentiviral-mediated GT. A 1-year follow-up showed stabilization in blood lineages, without any serious adverse effects from GT. A metaregression analysis could not be conducted, as very little long-term follow-up data of patients was observed, and the median survival rate could not be calculated. Thus, we can conclude that GT seems to be a safe procedure in FA; however, further research needs to be conducted on the longitudinal clinical effects of GT in FA, for a better insight into its potential to become a standard form of treatment.

Knowledge and Attitude of Teenagers Towards Electronic Cigarettes in Karachi, Pakistan.

Introduction Studies have shown that electronic cigarettes have gained immense popularity and their use has increased dramatically all over the world. However, little is known about the knowledge and attitudes towards e-cigarettes in third world countries such as Pakistan. The aim of this study was to determine the perceptions of teenagers in Karachi regarding e-cigarettes and whether the differences in said perceptions were affected by gender and level of education. Methods We conducted a cross-sectional study in January 2017 using convenience sampling and interviewed 441 young individuals, aged 13 to 19 years, to determine their knowledge, attitudes, and practices regarding e-cigarettes. The participants were questioned about their knowledge and its source. Attitudes were judged using four and five-point Likert scales while questions regarding practices focused on single and current use. Chi-square and Mann-Whitney tests were applied to compare the knowledge, attitudes, and practices of teenagers with gender and level of schooling. Results The majority of participants knew what e-cigarettes were (n=277, 68.7%) but did not know about their contents (n=225, 55.8%) and had learned about them from either friends or the internet (n=245, 60.%). Almost half of them (n=190, 47.2%) believed that the reason for e-cigarette use was either peer pressure or to quit smoking conventional cigarettes. An overwhelming majority also stated that; it was either easy or very easy to obtain e-cigarettes (n=277, 68.7%), they would not try smoking e-cigarettes even if a good friend of theirs recommended them (n=287, 71.2%), they were not current e-cigarette smokers (n=370, 91.8%) and they would never promote e-cigarette use (n=371, 92.1%). Statistically significant differences were found with males knowing more about e-cigarettes (p=0.006) and being more common to either have smoked (p <0.001) or be current e-cigarette smokers (p <0.001). Furthermore, middle school students were more likely to have negative attitudes towards e-cigarettes believing they were more harmful (p=0.003) and more addictive (p <0.001) than conventional cigarettes. Conclusion Many people were aware of what electronic cigarettes are but still, it was evident that there was the lack of proper knowledge along with negative attitudes towards e-cigarette use among teenagers in Pakistan due to cultural and social stigmas and lack of advertising. Males and females had considerable differences in their opinions regarding e-cigarette use owing to such social practices being considered taboo by females and males having greater freedom due to patriarchal, familial and cultural systems.
