Background Neonatal mortality due to preterm birth and low birthweight remains a significant challenge in Pakistan. Kangaroo mother care (KMC) is a unique, low-cost intervention proven to reduce neonatal mortality and morbidity and increase exclusive breastfeeding rates. However, KMC has not been attempted in community settings in Pakistan. We aim to implement and evaluate the effectiveness of a community-based KMC package to reduce neonatal morbidity and mortality among preterm and low birthweight (LBW) infants, which will provide evidence for policy development and the large-scale implementation of KMC across the country. Objective The primary objective of this trial is to reduce neonatal mortality among preterm and LBW infants. The secondary objectives are growth (measured as weight gain), reduced incidence of possible serious bacterial infection, and increased exclusive breastfeeding and continued breastfeeding practices. Methods We designed a community-based cluster randomized ...

Stunting predominantly occurs during the first 1000 days of life and continues to the age of five years. We will aim to assess the effectiveness of specialized nutritious foods (SNF)and social and behavior change communication (SBCC) strategies during the first 1000 days of life to prevent stunting among children in two rural districts of Badakhshan, Afghanistan. This will be a quasi-experimental pre-post study with the control group utilizing qualitative and quantitative methods. Before launching the program, formative research will be conducted on the acceptability, appropriate use and SBCC strategies needed to support the introduction of intervention package. Repeated cross-sectional baseline and endline surveys will be conducted in both the intervention and the control districts. After the formative research and baseline household survey, an intervention focusing on the provision of SNF, targeting pregnant and lactating women and children 6–23 months, and SBCC strategies will be...

BackgroundSocio-economic, nutritional, and infectious factors have been associated with impaired infant growth, but how the presence of these factors during infancy affects growth around 5 years is not well understood.MethodsThis secondary analysis of the MAL-ED cohort included 277 children from Pakistan for whom socio-demographic, breastfeeding, complementary foods, illness, nutritional biomarkers, stool pathogens and environmental enteropathy indicators between 0 and 11 months were recorded. We used linear regression models to analyze associations of these indicators with height-for-age (HAZ), weight-for-age (WAZ) and weight-for-height (WLZ) at 54–66 months (~5 years), and Poisson regression with robust standard errors to estimate risk ratios for stunting and underweight ~5 years, controlling for gender, first available weight, and income.ResultsAmong the 237 infants followed longitudinally and evaluated at about 5 years of age, exclusive breastfeeding was short (median = 14 days)...

Background Breast cancer is the most common malignancy in women, affecting over 1.5 million women every year, which accounts for the highest number of cancer-related deaths in women globally. Hereditary breast cancer (HBC), an important subset of breast cancer, accounts for 5–10% of total cases. However, in Low Middle-Income Countries (LMICs), the population-specific risk of HBC in different ethnicities and the correlation with certain clinical characteristics remain unexplored. Methods Retrospective chart review of patients who visited the HBC clinic and proceeded with multi-gene panel testing from May 2017 to April 2020. Descriptive and inferential statistics were used to analyze clinical characteristics of patients. Fisher’s exact, Pearson’s chi-squared tests and Logistic regression analysis were used for categorical variables and Wilcoxon rank-sum test were used for quantitative variables. For comparison between two independent groups, Mann-Whitney test was performed. Results we...

Purpose We aimed to assess the effectiveness of wheat soya blend plus (WSBP) provided during pregnancy and lactation on weight gain during pregnancy, reduction of low birthweight (LBW), and improvement in nutritional status in infants at 6 months of age in Thatta and Sujawal districts of Sindh, Pakistan. Methods A cluster randomized-controlled trial was conducted in Thatta and Sujawal districts in Pakistan from August 2014 to December 2016. A total of 2030 pregnant women were enrolled in the study. These women and their infants were followed during pregnancy and first 6 months of life. Pregnant women received a monthly ration of 5 kg (i.e., 165 g/day) of WSB + during pregnancy and the first 6 months of their lactation period. Results There was no difference in weight gain during pregnancy between the intervention and control groups ( n = 496, 326.7 g/week 95% CI 315.2–338.1 vs. ( n = 507, 306.9 g/week, 95% CI 279.9–333.9 P = 0.192), after adjustment with different factors. The reduction in the prevalence of LBW was not different between intervention and control groups ( n = 325, 34.0%, 95% CI 31.7–36.4, vs. ( n = 127, 34.3%, 95% CI 27.2–41.5, P = 0.932). Significant reductions in risk of stunting ( n = 1319 RR 0.85, 95% CI 0.73–0.99, P = 0.041), wasting ( n = 1330 RR 0.77, 95% CI 0.65–0.91, P = 0.003), and underweight ( n = 1295 RR 0.77, 95% CI 0.69–0.87, P < 0.001) were observed in infants at 6 months of age in the intervention as compared to the control group. However, no difference was noted on reduction in the risk of stunting among infants at 6 months of age in the intervention and control group ( n = 1318 RR 0.91, 95% CI 0.78–1.07, P = 0.253) after adjustment. A significant reduction in anemia was noted ( n = 1328 RR 0.94, 95% CI 0.91–0.98, P = 0.002) in infants at 6 months of age in the intervention as compared to the control group in adjusted analysis. Conclusions Provision of WSB + during pregnancy and the first 6 months of lactation is effective in reducing the risk of under nutrition and anemia in infants at 6 months of age. This study can potentially guide the government and donor agencies in investing in nutritional programmes, especially for pregnant and lactating women living in vulnerable settings.

We compared the impact of management of severe acute malnutrition (SAM) by lady health workers (LHWs) at a community level with the standard CMAM program provided at the health facility. A two-arm cluster randomised controlled trial was conducted in a rural district in sindh Pakistan. The primary outcome was recovery from SAM and secondary outcomes were relapse, defaulter and mortality rate. A total of 829 children were recruited in the trial (430 in intervention and 399 in control groups). No significant difference was noted in recovery rate between the intervention and control groups (79.2% vs 85.6%, p = 0.276). Similarly, no significant differences were noted in relapse (p = 0.757), weight gain (p = 0.609), deaths (p = 0.775) and defaulter rate (p = 0.324) across the groups. Compliance of RUTF was significantly higher in the control group (93%) than in the intervention group (87%), p < 0.000. Our results showed no impact of SAM treatment on performance indicators of CMAM (recovery, relapse, death and default) between the standard CMAM programme performed at the health facility by the government and NGO staff and the programme performed at health house level by the LHWs in Pakistan. We recommend further robust trials in other settings to confirm our results.

The world has made substantial progress in reducing maternal and child mortality, but many countries are projected to fall short of achieving their Millennium Development Goals (MDGs) 4 and 5 targets. The major objective of this paper is to examine progress in Pakistan in reducing maternal and child mortality and malnutrition over the last two decades. Data from recent national and international surveys suggest that Pakistan lags behind on all of its MDGs related to maternal and child health and, for some indicators especially related to nutrition, the situation has worsened from the baseline of 1990. Progress in addressing key social determinants such as poverty, female education and empowerment has also been slow and unregulated population growth has further compromised progress. There is a need to integrate the various different sectors and programmes to achieve the desired results effectively and efficiently as many of the determinants and influencing factors are outside the hea...

High vaccine coverage at the district level may not translate with the same vigor to subdistrict levels; therefore, it is important to understand coverage inequalities. This study underscored vaccine coverage inequalities at subdistrict levels and explored reasons for immunization failure in a high-performing rural district of Pakistan. Parents of children aged 12 to 23 months were randomly selected and interviewed for child’s vaccination history through a cross-sectional survey in 2008. Using secondary data (GIS maps and population census), coverage was plotted in respect to sociodemographic and presence of lady health workers. The proportion of children fully immunized was found notably low (75%) than officially reported (85%). Coverage inequalities were observed at subdistrict levels, ranging from 58% to 85% in rural to urban areas and from 60% to 80% in lower to higher income quintiles. Distance to immunization facility, parental unawareness, and wrong ideas about vaccination we...

Background There is limited evidence between contraceptive use, availability of commodities and distance to the facility in developing countries. Distance to the facility is an essential determinant of contraceptive use. Still, women may not seek family planning services from the nearest facility and may be prepared to travel the farthest distance to receive quality family planning services. Methods We analyzed women's survey data linked to health facility data and applied an alternate specific conditional logit model to examine the distance a woman is prepared to travel and the quality of services offered by facilities in urban areas in Karachi, Pakistan. Results This study analyzed data from 336 women and 28 facilities and identified that the mean distance to the nearest facility was 0.44 km; the chosen facility was, on average, 5 km away. Women preferred facilities that offered a range of contraceptive methods and additional services provided by female healthcare providers on...

Despite the frequency of stillbirths, the subsequent implications are overlooked and underappreciated. We present findings from comprehensive, systematic literature reviews, and new analyses of published and unpublished data, to establish the effect of stillbirth on parents, families, health-care providers, and societies worldwide. Data for direct costs of this event are sparse but suggest that a stillbirth needs more resources than a livebirth, both in the perinatal period and in additional surveillance during subsequent pregnancies. Indirect and intangible costs of stillbirth are extensive and are usually met by families alone. This issue is particularly onerous for those with few resources. Negative effects, particularly on parental mental health, might be moderated by empathic attitudes of care providers and tailored interventions. The value of the baby, as well as the associated costs for parents, families, care providers, communities, and society, should be considered to preve...

Abstract Background The study was aimed at evaluating prognostic factors and treatment outcomes of pediatric parameningeal rhabdomyosarcoma (PM-RMS) at two major pediatric oncology centers in Pakistan. Methods PM-RMS age 1–16 years diagnosed from 2005 to 2015 at Aga Khan University Hospital and The Indus Hospital were identified. Factors relevant to survival and relapse were analyzed. Results Forty-Six patients were identified. Thirty-three (72%) patients were analyzed. Seventeen (52%) patients were stage III (group-III), 15 (46%) were stage II (group-III) and 1 (3%) was stage IV (group-IV). Twenty-nine (88%) were embryonal. Majority (n = 25, 76%) received vincristine, actinomycin and cyclophosphamide while three (9%) received high-risk protocol. Twenty-three (69.6%) received radiation whereas two (6%) patients each were treated with surgery and surgery + radiation. Improved 3-year overall survival (OS) (77%, P = 0.04) was associated with a dose of 50Gy radiation and (77%, P = 0.02) with baseline nutritional status Z-scores ≥ - 2SD. Age ≥10 years (33%, P = 0.80), stage III disease (33%, P = 0.08) and regional nodal involvement (25%, P = 0.12) showed inferior 3-year event free survival (EFS). Three-year overall survival (OS) was 37% (95% CI: 16%-58%), 3-year (OS) excluding treatment abandonment was 47% (95% CI: 21%-70%) and 3-year event free survival with relapse, deaths and treatment abandonment was 23% (95% CI: 9%-41%) respectively. Conclusion Our study demonstrates improved survival with adequate dose of radiation and nutritional status (Z-scores) ≥ - 2SD. Less advanced disease and lack of nodal involvement correlates well with outcomes. Treatment abandonment remains problematic in developing countries. Retrospective analysis restricted meaningful outcomes, suggesting future collaborative studies.

Small for gestational age (SGA) infants are more susceptible to infectious morbidity and growth faltering compared to their appropriate for gestational age (AGA) counterparts. Zinc supplementation of SGA infants may be beneficial but the underlying susceptibility to zinc deficiency of SGA infants has not been examined. In a community-based, observational, longitudinal study in a peri-urban settlement of Karachi, Pakistan, we compared the size of the exchangeable zinc pools (EZP) in term SGA and AGA infants at birth and at 6 months of age, hypothesizing that the EZP would be lower in the SGA group. To measure EZP size, a zinc stable isotope was intravenously administered within 48 hours of birth (n = 17 and 22) at 6 months (n = 11 and 14) in SGA and AGA infants, respectively. Isotopic enrichment in urine was used to determine EZP. No significant difference was detected in the mean (± SD) EZP between SGA and AGA infants at birth, with values of 9.8 ± 3.5 and 10.1 ± 4.1 mg/kg, respecti...

BackgroundPneumonia is a leading cause of death among children under 5 specifically in South Asia and sub-Saharan Africa. Hypoxaemia is a life-threatening complication among children under 5 with pneumonia. Hypoxaemia increases risk of mortality by 4.3 times in children with pneumonia than those without hypoxaemia. Prevalence of hypoxaemia varies with geography, altitude and severity (9%–39% Asia, 3%–10% African countries). In this protocol paper, we describe research methods for assessing impact of Lady Health Workers (LHWs) identifying hypoxaemia in children with signs of pneumonia during household visits on acceptance of hospital referral in district Jamshoro, Sindh.Methods and analysisA cluster randomised controlled trial using pulse oximetry as intervention for children with severe pneumonia will be conducted in community settings.

Background In Pakistan, the prevalence of stunting among children under-five years has remained above WHO critical thresholds (≥30%) over the last two decades. Objective We hypothesized that an unconditional cash transfer (UCT) combined with lipid-based nutrient supplement (LNS) and/or social and behavior change communication (SBCC) will prevent stunting among children 6-23 months of age. Design This was a four-arm, community-based cluster randomized controlled trial conducted in the district of Rahim Yar Khan, Pakistan. A total of 1729 children (UCT n = 434); (UCT+SBCC n = 433); (UCT+LNS n = 430) and (UCT+LNS+SBCC n = 432) were enrolled at 6 months of age and measured monthly for 18 months until the age of 24 months. Results At 24 months of age, children who received UCT+LNS (rate ratio [RR], 0.85 [95% CI 0.74, 0.97]; P = 0.015); and UCT+LNS+SBCC (RR, 0.86 [95% CI 0.77, 0.96]; P = 0.007) had significantly lower risk of being stunted as compared to the UCT arm.

BackgroundVitamin D deficiency during pregnancy is a public health problem in Pakistan and is prevalent among most women of reproductive age in the country. Vitamin D supplementation during pregnancy is suggested to prevent adverse pregnancy outcomes and vitamin D deficiency in both the mother and her newborn.MethodsWe conducted a double-blinded, randomised controlled trial in Karachi, Pakistan to evaluate the effect of different doses of vitamin D supplementation during pregnancy on biochemical markers (serum 25(OH)D, calcium, phosphorus and alkaline phosphatase) in women and neonates, and on pregnancy and birth outcomes (gestational diabetes, pre-eclampsia, low birth weight, preterm births and stillbirths).ResultsPregnant women (N=350) in their first trimester were recruited and randomised to three treatment groups of vitamin D supplementation: 4000 IU/day (group A, n=120), 2000 IU/day (group B, n=115) or 400 IU/day (group C, n=115).

Serial household antibody sero-surveys informs the pandemic where testing is nonuniform. Young populations with intergenerational co-residence may have different transmission dynamics. We conducted two serial cross-sectional surveys in April and June 2020 in low- and high-transmission neighborhoods of Karachi, Pakistan, using random sampling. Symptoms were assessed and blood tested for antibody using chemiluminescence. Seroprevalence was adjusted using Bayesian regression and post stratification. CRI with 95% confidence intervals was obtained. We enrolled 2004 participants from 406 households. In June 8.7% (95% CI 5.1-13.1) and 15.1% (95% CI 9.4 -21.7) were infected in low- and high-transmission-areas respectively compared with 0.2% (95% CI 0-0.7) and 0.4% (95% CI 0 - 1.3) in April. Conditional risk of infection was 0.31 (95% CI 0.16-0.47) and 0.41(95% CI 0.28-0.52) in District Malir & District East respectively with overall only 5.4% symptomatic.

Introduction In conflict affected countries, healthcare delivery remains a huge concern. Pakistan is one country engulfed with conflict spanning various areas and time spans. We aimed to explore the effect of conflict on provision of reproductive, maternal, newborn, child and adolescent health and nutrition (RMNCAH&N) services and describe the contextual factors influencing the prioritization and implementation in conflict affected areas of Pakistan (Balochistan and FATA). Method We conducted a secondary quantitative and a primary qualitative analysis. For the quantitative analysis, we stratified the various districts/agencies of Balochistan and FATA into the conflict categories of minimal-, moderate- and severe based on accessibility to health services through a Delphi methodology with local stakeholders and implementing agencies and also based on battle-related deaths (BRD) information from Uppsala Conflict Data Program (UCDP).

BackgroundIn low- and middle-income countries, women often use inappropriate materials to manage menstruation, which can pose a hazard to their health. Inappropriate menstrual hygiene management (MHM) can also have important downstream consequences beyond physiologic health, including the restriction of adolescent girls’ access to academic pursuits. This impacts one’s quality of life and has potential economic consequences for society. Methods Among menstruating adolescent and young women 15-23 years of age living in rural Pakistan (n = 25,305), we aimed to describe MHM practices and generate a predictive model of the socioeconomic and demographic factors related to the use of MHM materials. Beliefs and barriers around MHM were also summarized. The outcome variable included: those who practiced appropriate (reported use of a sanitary pad or/and new piece of cloth) and inappropriate MHM (reported use of an old cloth and/or nothing). Logistic regression was used to generate the predic...

Objective:The objective of this study was to assess differences in myocardial systolic and diastolic function and vascular function in children 2−5 years of age born to diabetic as compared to non-diabetic mothers.Methods:This study was a retrospective cohort conducted in 2016 at The Aga Khan University Hospital, Karachi, Pakistan. It included children between 2 and 5 years of age born to mothers with and without exposure to diabetes in utero (n = 68 in each group) and who were appropriate for gestational age. Myocardial morphology and function using echocardiogram and carotid intima media thickness (cIMT) and pulse wave velocity was performed to evaluate cardiac function as well as macrovascular remodelling in these children. Multiple linear regression was used to compare the groups.Results:There was no significant difference in cardiac morphology, myocardial systolic and diastolic function, and macrovascular assessment between the exposed and unexposed groups of AGA children.
