Objective: To study the prevalence of stroke and associated risk factors in Khyber Pakhtunkhwa (KP) province of Pakistan. Methods: This study was a part of cross-sectional KP Integrated Population Health Survey 2016-17 conducted on population aging ≥18 years at 24 districts of KP. Primary (n=1061) and secondary sampling units (n=15724) were developed, based on urban/rural and socio-economic status. Each primary-unit comprised of 250-300 households. Sample was selected through a multi-staged stratified systematic cluster sampling technique by taking every 16th household per rural and every 12th household per urban-unit. A validated “Cincinnati Stroke Scale” for identification of stroke patients in community was used along with demographics and potential risk factors. Results: Among the 15724 randomly selected households, 22500 participants (51.4% females; 74.6% rural areas, mean age 42±12.6 years) were interviewed. Stroke was identified in 271 cases (137 males, 134 females; Mean age=43.39±0.85 years) and prevalence of stroke was 1.2% (1200 per 100,000 population). Obesity/overweight (38.8%), hypertension (21.8%), smoking (6.6%) and known diabetes mellitus (5.9%) were the common associated risk factors of stroke. Age groups >60 years (adjusted OR=1.68; 95% CI: 1.05-2.68); urban area (adjusted OR=1.68; 95% CI: 1.29-2.19); unemployment (adjusted OR=3.78; 95% CI: 2.49-5.73) and lower formal (primary) education (adjusted OR 2.18; 95% CI: 1.30-3.64) were significantly associated with stroke (p <0.05). Conclusion: Prevalence of stroke is 1.2% in the province of KP. Obesity, hypertension, smoking and Diabetes Mellitus are the common associated risk factors of stroke. Higher age, urban area, unemployment and lower formal education are significantly associated with stroke. doi: https://doi.org/10.12669/pjms.36.7.2824 How to cite this:Sherin A, Ul-Haq Z, Fazid S, Shah BH, Khattak MI, Nabi F.

In Pakistan, there is limited evidence for the levels and relationship of 25 (OH) Vitamin D (25(OH)D) status in pregnant women and their newborns, while the association between maternal 25(OH)D and newborn anthropometric measurements remains unexplored. Sociodemographic data were collected from 213 pregnant mothers during their visit to a tertiary care hospital at the time of childbirth. Anthropometric measurements were performed on all mothers and their newborns and blood samples collected from both for 25(OH)D levels. Participants were classified into two groups according to their 25(OH)D status: sufficient (25(OH)D ≥50 nmol L⁻¹) and deficient (25(OH)D <50 nmol L⁻¹). Simple and multiple regression models were used for analysis. Among 213 pregnant women, prevalence of 25(OH)D deficiency was 61.5%, and their newborn was 99.5% (mean 25(OH)D levels: 46.3 [11.3] and 24.9 [5.4] nmol L⁻¹, respectively). Maternal sociodemographic characteristics were similar between 25(OH)D deficient and sufficient mothers, whereas newborn 25(OH)D levels were significantly lower in the former (22.60 [4.53] vs. 27.67 [3.82] nmol L⁻¹, respectively, P < 0.001). There was a strong positive association between maternal and newborn 25(OH)D levels (r, 0.66; r², 43%, B [SE], 0.3 [0.02]; P < 0.001). Association of maternal 25(OH)D levels with newborn weight, length and head circumference was not significant (all P > 0.05). Our study shows a high prevalence of 25(OH)D deficiency in pregnant women and their newborns and a strong positive association between maternal and newborn 25(OH)D levels. Findings of this study indicate the importance of maintaining sufficient 25(OH)D levels during pregnancy.

Healthcare workers are at the highest risk of contracting novel coronavirus disease 2019 (COVID-19) and, therefore, require constant protection. This study assesses access to personal protective equipment (PPE), availability of adequate information about PPE use, self-reported ability to correctly wear and remove (donning and doffing) PPE, and risk perceptions associated with COVID-19 among frontline healthcare workers in Pakistan. Using a structured and validated questionnaire, an online survey was conducted from May 9 to June 5, 2020. Responses were received from 453 healthcare workers. Of these, 218 (48.12%) were doctors, 183 (40.40%) were nurses, and 52 (11.48%) were paramedical staff. Only 129 (28.48%) healthcare workers reported having adequate access to PPE at all times, whereas 156 (34.44%) never had access to PPE and 168 (37.09%) had access to PPE occasionally. Lack of access to PPE led the majority (71.74%) of healthcare workers to use coping strategies such as reuse of N95 and surgical masks. A total of 312 (68.87%) respondents believed that the risk of contracting COVID-19 in the work environment was high and the majority (62.69%) adopted precautionary measures at home to keep their families safe. A significantly high (n = 233, 51.43%, P = .03) number of respondents reported self-medicating. Of all the respondents, only 136 (30.02%) were tested for COVID-19 at least once, of which 32 (23.53%) ever tested positive. These findings suggest that healthcare workers in Pakistan had limited access to PPE. Adequate provision and training is vital to protect the healthcare workforce during the COVID-19 pandemic.

Pakistan has hosted millions of Afghan refugees over the last several decades. Due to poor socioeconomic status, food insecurity and inadequate access to health care, these refugees are considered to be at high risk of malnutrition. Previous studies on nutritional assessment of high-risk populations (refugees) have focused mainly on women and children (0–59 months). The current study aims to assess nutritional status of adolescent Afghan refugees; the population who are equally vulnerable to malnutrition and its consequences. In this cross sectional study, the nutritional status of 206 adolescent (10–19 years old) Afghans boys and girls living in a refugee camp in Peshawar, Pakistan was assessed using standard methods. The results indicate a prevalence of stunting, thinness, and overweight and obesity at 35.3%, 4.4% and 14.8%, respectively. Furthermore, there was a significantly high prevalence of micronutrient deficiencies (vitamin D, 80.5%; vitamin B12, 41.9%; and folate, 28.2%); and anemia (10.1%). Together, these findings indicate that this vulnerable population group suffers from the double burden of malnutrition and are thus at serious risk of impaired psychosocial cognitive development, general ill-health and diminished wellbeing. This study therefore highlights the urgent need to include adolescents in regular screening and intervention programs of such at-risk populations.

Background: The World Health Organization (WHO) has strongly advocated health systems' preparedness for effective management of crisis situations globally for more than two decades. Pakistan is known for its high vulnerability to hazards and lack of coping and adaptive capabilities. Health systems' preparedness for locales with such high-risk profile is essential, yet there is a dearth of studies addressing the status of such preparedness in the country. Aims: This study aimed to assess the status of preparedness of health-system components for crisis management in the most disaster prone districts of Pakistan. Methods: A purposive sample of 12 of the most disaster prone districts in two provinces of Pakistan was evaluated for preparedness using the WHO's toolkit for assessing health-system capacity for crisis management. Six core functions of the Health Systems Framework, with a total of 229 indicators, were evaluated at the district management as well as secondary and tertiary health care facilities level. Proportions of indicators prepared were calculated and preparedness was classified as Acceptable (>= 66%), Partial (36-65%) or Inadequate (<= 35%). Results: Seventy-two percent, 95% Confidence Interval [46.0, 90.0] of indicators in these most vulnerable districts were evaluated as partially or inadequately prepared for appropriate management of crises. Even the highest scoring core function, Leadership and Governance was partially prepared with a score of 53.6% (52.4, 54.9). Process elements were found to be less prepared compared with structure components. Conclusions: Federal level strategic planning, implementation, management and follow-up aimed at ensuring health-systems' preparedness need to be reviewed and strengthened.

Cost-effective interventions are needed to address undernutrition, particularly micronutrient deficiencies, which are common in children under the age of five in low- and middle-income countries. A community-based, non-randomized clinical trial was undertaken in the Kurram district of Khyber Pakhtunkhwa from January 2018 to June 2019, to evaluate the effect of locally produced micronutrient powder (local name: Vita-Mixe) on plasma micronutrient status, hemoglobin level, and anthropometric outcomes. Children aged 24–48 months old were recruited and allocated to the intervention and control arm of the study. The enrolled children in the intervention arm received one micronutrient powder (MNP) sachet for consumption on alternate days for 12 months. To assess the impact of the intervention on plasma levels of zinc, vitamin D, vitamin A, and hemoglobin level, blood samples were taken at baseline and after one year following the intervention. The analysis was conducted using Enzyme-Linked Immunosorbent Assay (ELISA), atomic absorption spectrometry, and an automated hematology analyzer. For the impact on growth parameters, the anthropometric assessment was performed using WHO standard guidelines. A 24 h dietary recall interview was used to assess the nutrient intake adequacy. Results showed that in the intervention arm, children had on average a 7.52 ng/mL (95% CI 5.11–9.92, p-value < 0.001) increase in the plasma level of vitamin A, 4.80 ng/mL (95% CI 1.63–7.95, p-value < 0.002) increase in vitamin D levels and 33.85 µg/dL (95% CI 24.40–43.30, p-value < 0.001) increase in the plasma zinc level, as well as a 2.0g/dL (95% CI 1.64–2.40, p-value < 0.001) increase in hemoglobin level. Statistically significant improvement was observed in the weight-for-height z-score (WHZ) (from −1.0 ± 0.88 to −0.40 ± 1.01, p < 0.001) and weight-for-age z-score (WAZ) (from −1.40 ± 0.50 to −1.05 ± 0.49, p < 0.001) in the intervention group compared to the control group. No statistically significant change was observed in the height-for-age z-score (HAZ) in the intervention group (p = 0.93). In conclusion, micronutrient powder supplementation is a cost-effective intervention to improve the micronutrient status, hemoglobin level, and growth parameters in under-five children, which can be scaled up in the existing health system to address the alarming rates of undernutrition in Pakistan and other developing countries.
