The Agenda Building Role of Television on Science & Technology Developments: Comparative Study between Private and State-Run TV Channels Coverage

This study is about the agenda building role of television in Pakistan, in the state and private news bulletins, and treatment of Science & Technology news for creating public awareness. The study is of 9am prime time news bulletins of March 2016. Manifest content analysis technique along with a specifically designed code sheet was used in this research. Results show that there was a significant difference between private and state run news bulletins. In the state run PTV news though the news were given prominence, it can be attributed to government projects, future plans, meeting sessions and even public addresses of the political leaders about Science & Technology, making no thoughtful contribution in educating the audience in Science & Technology develoments.&nbsp

Epidemiology of asthma and associated factors in an urban Pakistani population: Adult asthma study-Karachi

Background: This study was conducted in order to determine the prevalence of asthma and associated risk factors in the adult population of Karachi, Pakistan.Methods: This multi-stage, cross-sectional survey was conducted from May 2014-August 2015; comprising 1629 adults in 75 randomly selected clusters in Karachi, Pakistan. Definitions included: \u27self-reported asthma\u27, \u27reversibility in FEV1\u27 and \u27respiratory symptoms and reversibility in FEV1\u27.Results: Prevalence of asthma was 1.8% (self-reported) (95% CI: 1.0-2.6), 11.3% (reversibility in FEV1) (95% CI: 9.4-13.3) and 6.6% (symptoms and reversibility in FEV1) (95% CI: 5.1-8.1). Asthmatics were more likely to belong to the age group ≥38 years according to \u27reversibility in FEV1\u27 and \u27respiratory symptoms and reversibility in FEV1\u27 (AOR: 1.9, 95% CI: 1.2-3.3) and (AOR: 2.1, 95% CI: 1.1-4.2), respectively. Asthmatics were more likely to report history of allergies (AOR: 1.9, 95% CI: 1.2-2.9) and (AOR: 2.8, 95% CI: 1.7-4.8); and were exposed to environmental tobacco smoke (AOR: 1.6, 95% CI: 1.1-2.5) and (AOR: 1.9, 95% CI: 1.1-3.3) according to \u27reversibility in FEV1\u27 and \u27respiratory symptoms and reversibility in FEV1\u27, respectively. Asthmatics were more likely to report pack years of smoking ≥5 (AOR: 2.3, 95% CI: 1.1-4.7) according to \u27respiratory symptoms and reversibility in FEV1\u27.Conclusion: This study reports a high prevalence of asthma among Pakistani adults and calls for developing appropriate public health policies for prevention and control of asthma in the country. Further studies should be conducted to determine the national prevalence as well as follow-up studies to identify preventable causes for adult asthma

Implications of Early Pregnancy Obesity on Maternal, Fetal and Neonatal Health: Retrospective cohort study from Oman

Objectives: This study aimed to determine the prevalence of early pregnancy obesity among Omani women and to review maternal antenatal complications, intrapartum and postpartum events and neonatal complications among such women in comparison to women of normal weight. Methods: This retrospective cohort study included 2,652 pregnant Omani women who delivered at the Royal Hospital, Muscat, Oman, between November 2011 and April 2012. The patients’ electronic medical records were reviewed for antenatal, intrapartum and postpartum data. Body mass index was measured during the first trimester (≤12 gestational weeks) and classified according to the World Health Organization categories. Maternal and neonatal complications were compared between obese women and those of normal weight. Obstetric outcomes in uncomplicated pregnancies were also compared. Results: In the study cohort, there were 901 (34%) obese women and 912 (34.4%) women of normal weight; of these, 440 (48.8%) and 672 (73.7%) had uncomplicated pregnancies, respectively. Obese women had a significantly increased incidence of gestational diabetes (relative risk [RR]: 2.23; 95% confidence interval [CI]: 1.70–2.92; P <0.01), gestational hypertension (RR: 3.04; 95% CI: 1.63–5.65; P <0.01), Caesarean delivery (RR: 1.48; 95% CI: 1.08–2.03; P <0.01), postpartum haemorrhage (RR: 2.10; 95% CI: 1.11–4.10; P = 0.01) and fetal macrosomia (RR: 2.71; 95% CI: 1.21–6.09; P <0.01). Conclusion: Approximately one-third of the studied Omani women were obese. These women had a significantly increased risk of various maternal antenatal complications, intrapartum and postpartum events and neonatal complications

Role of iron in the reduction of anemia among women of reproductive age in low-middle income countries: Insights from systematic review and meta-analysis

Background: Iron deficiency anemia is a common public health issue among women of reproductive age (WRA) because it can result in adverse maternal and birth outcomes. Although studies are undertaken to assess iron efficacy, some gaps and limitations in the existing literature need to be addressed. To fill the gaps, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) assessing the role of iron in reducing anemia among WRA in low-middle-income countries (LMICs).Methods: A comprehensive search strategy was used to search Medline through PubMed, Embase, and Science Direct for RCTs published between 2000 and 2020. The primary outcome was the mean change in hemoglobin level. We used standardized mean differences and their respective 95% CI to estimate the pooled effect. We used I2 statistics and Egger\u27s test to assess heterogeneity and publication bias, respectively. This review was carried out in accordance with revised guidelines based on the Preferred Reporting Items for Systematic Review and Meta-analysis.Results: The findings showed that iron therapy improved hemoglobin and ferritin levels, though the results varied across studies. An overall pooled effect estimate for the role of iron therapy in improving the hemoglobin levels among WRA was -0.71 (95% CI: -1.27 to -0.14) (p = 0.008). Likewise, the overall pooled effect estimate for the role of iron therapy in improving the ferritin levels among WRA was -0.76 (95% CI: -1.56 to 0.04) (p = 0.04). The heterogeneity (I2) across included studies was found to be statistically significant for studies assessing hemoglobin (Q = 746.93, I2 = 97.59%, p = 0.000) and ferritin level (Q = 659.95, I2 = 97.88%, p = 0.000).Conclusion: Iron therapy in any form may reduce anemia\u27s burden and improve hemoglobin and ferritin levels, indicating improvement in iron-deficiency anemia. More evidence is required, however, to assess the morbidity associated with iron consumption, such as side effects, work performance, economic outcomes, mental health, and adherence to the intervention, with a particular focus on married but non-pregnant women planning a pregnancy in the near future.Trial registration: Registered with PROSPERO and ID is CRD42020185033

Burden of asthma among children in a developing megacity: Childhood asthma study, Pakistan

Objectives: Global burden of childhood asthma has increased in the past few decades, particularly in low-income countries. In Pakistan, there is a lack of community-based epidemiological studies estimating the burden of asthma among children. This study determined the prevalence and predictors of asthma among children 3-17 years of age in Karachi, Pakistan.Methods: A two-stage community-based representative cross-sectional survey was conducted in Karachi from March 2012 to April 2013 comprising 1046 children aged 3-17 years. Of 7500 clusters, 80 were randomly selected, and of these, 15 children per cluster were enrolled randomly. A translated and pre-tested version of International Study of Asthma and Allergies in Children questionnaire was administered.Results: The overall prevalence of asthma among study participants was 10.2% (95% CI: 8.4-12.0). Asthma was more likely to occur among boys (adj. OR: 2.5, 95% CI: 1.6-4.0), children in the younger age group (3-7 years) (adj. OR: 2.9, 95% CI: 1.7-4.8), those living in households with ill-ventilated kitchens (adj. OR: 1.8, 95% CI: 1.1-3.1), having family history of asthma (adj. OR: 2.3, 95% CI: 1.3-3.9) and those of the Sindhi ethnicity (adj. OR: 2.2, 95% CI: 1.1-4.4).Conclusion: This study is the first robust evidence regarding asthma among children in Pakistan, reporting a high burden in this group. Family history, male gender, Sindhi ethnicity and ill-ventilated kitchen were identified as important predictors of asthma. Targeted preventive measures and intervention studies are required to better understand and reduce the burden of asthma among children in Pakistan

Exposure assessment of lead from food and airborne dusts and biomonitoring in pregnant mothers, their fetus and siblings in Karachi, Pakistan and Shimotsuke, Japan.

AIM: Exposure assessment of lead (Pb) and Arsenic (As) from food, water, and house dust intake were assessed among pregnant women, their children and fetuses in Pakistan and Japan, as well as their body burden of the metals in their blood. METHOD: Fifty families which included a pregnant woman, a fetus and the 1-3-year-old siblings were recruited in Karachi and Khairpur in Pakistan, and Shimotsuke and Asahikawa in Japan, respectively. Their dietary exposure to Pb and As was measured in 3-day food duplicates and drinking water by ICP-MP. Pb in house dust and respirable dust was evaluated with an energy dispersive X-ray fluorescence spectrometry. Non-radioactive isotope Pb profiles of blood specimens will be compared with those of the exposure origins, such as food duplicates, respirable house dust, the soils nearby, and gasoline. RESULTS: Judging from the data collected and analyzed so far, contribution from dietary intake is highly correlated to higher body burden of Pb among Pakistani mothers. Additional data analyses will reveal the status of Pb and As body burden in Pakistani mothers, fetuses and their siblings, and causal sources of high body burden is delineated by Pb isotope profile analysis of different sources of Pb exposure
