RESUMO

BACKGROUND: The World Health Organization (WHO) recommends oral amoxicillin for patients who have pneumonia with tachypnea, yet trial data indicate that not using amoxicillin to treat this condition may be noninferior to using amoxicillin. METHODS: We conducted a double-blind, randomized, placebo-controlled noninferiority trial involving children at primary health care centers in low-income communities in Karachi, Pakistan. Children who were 2 to 59 months of age and who met WHO criteria for nonsevere pneumonia with tachypnea were randomly assigned to a 3-day course of a suspension of amoxicillin (the active control) of 50 mg per milliliter or matched volume of placebo (the test regimen), according to WHO weight bands (500 mg every 12 hours for a weight of 4 to <10 kg, 1000 mg every 12 hours for a weight of 10 to <14 kg, or 1500 mg every 12 hours for a weight of 14 to <20 kg). The primary outcome was treatment failure during the 3-day course of amoxicillin or placebo. The prespecified noninferiority margin was 1.75 percentage points. RESULTS: From November 9, 2014, through November 30, 2017, a total of 4002 children underwent randomization (1999 in the placebo group and 2003 in the amoxicillin group). In the per-protocol analysis, the incidence of treatment failure was 4.9% among placebo recipients (95 of 1927 children) and 2.6% among amoxicillin recipients (51 of 1929 children) (between-group difference, 2.3 percentage points; 95% confidence interval [CI], 0.9 to 3.7). Results were similar in the intention-to-treat analysis. The presence of fever and wheeze predicted treatment failure. The number needed to treat to prevent one treatment failure was 44 (95% CI, 31 to 80). One patient (<0.1%) in each group died. Relapse occurred in 40 children (2.2%) in the placebo group and in 58 children (3.1%) in the amoxicillin group. CONCLUSIONS: Among children younger than 5 years of age with nonsevere pneumonia, the frequency of treatment failure was higher in the placebo group than in the amoxicillin group, a difference that did not meet the noninferiority margin for placebo.

RESUMO

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 were considered significant at a p value of < 0.05. RESULTS: Out of 273 patients, 22% tested positive, 37% had a VUS and 41% had a negative genetic test result. Fifty-five percent of the positive patients had pathogenic variants in either BRCA1 or BRCA2, while the remaining positive results were attributed to other genes. Patients with a positive result had a younger age at diagnosis compared to those having a VUS and a negative result; median age 37.5 years, IQR (Interquartile range) (31.5-48). Additionally, patients with triple negative breast cancer (TNBC) were almost 3 times more likely to have a positive result (OR = 2.79, CI = 1.42-5.48 p = 0.003). Of all patients with positive results, 25% of patients had a negative family history of breast and/or related cancers. CONCLUSIONS: In our HBC clinic, we observed that our rate of positive results is comparable, yet at the higher end of the range which is reported in other populations. The importance of expanded, multi-gene panel testing is highlighted by the fact that almost half of the patients had pathogenic or likely pathogenic variants in genes other than BRCA1/2, and that our test positivity rate would have only been 12.8% if only BRCA1/2 testing was done. As the database expands and protocol-driven referrals are made across the country, our insight about the genetic architecture of HBC in our population will continue to increase.

RESUMO

BACKGROUND: Infertility is a major reproductive health problem in Pakistan. It has the potential to cause serious negative impact on a couple's marital life and psychological health. AIM: This study aimed to assess the factors associated with maladjustment among infertile couples. METHOD: An analytical cross-sectional design was employed. Validated scales were used to assess marital adjustment, depression, resilience and quality of life among infertile couples. Purposive sampling was employed to enrol 334 infertile couples from a private infertility medical centre, of Karachi, Pakistan. RESULTS: Among couples, marital adjustment scores were comparable, but resilience and quality of life were significantly low among wives whereas depression was significantly high among wives compared with husbands. Wives' marital adjustment was positively correlated with husband's resilience and quality of life and negatively related with his depression. After employing adjusted actor-partner interdependence modelling, wives' own depression and resilience had significant effect on their marital adjustment and their partner's resilience, depression and quality of life did not have any impact on their outcome. On the contrary, wives' resilience had a significant effect in increasing the marital adjustment of their husband. CONCLUSION: This study highlights the need to promote psychological support (resilience building skills) or couples' therapy to all those couples undergoing infertility treatment.

RESUMO

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

RESUMO

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.

RESUMO

OBJECTIVE: To evaluate the sensitivity of the modified Brief Form of Bruininks Oseretsky Test in identifying motor differences secondary to malnutrition and poverty. METHODS: This longitudinal cohort study was conducted at Nowshero Feroze, Sindh from 2013 to 2014 and comprised data drawn from children who participated in a randomised controlled trial, that assessed responsive stimulation and nutrition interventions in the first two years of life. Outcome measures included motor development assessed using Brief Form of Bruininks Oseretsky Test, child anthropometry and household economic and demographic information. Data was analysed using SPSS 15 and STATA 12. RESULTS: Of the 1058 children, 570(53%) were boys. Moderate-severe stunting was reported in 171(16.12%) subjects, while moderate-severe underweight was reported in 117(11.1%). Also, 591(56%) subjects belonged to poor families, 343(32%) had illiterate mothers, and 392(37%) were food-insecure. Malnutrition, socio-economic status and maternal literacy were significantly associated with a 6-item motor composite of the Brief Form of Bruininks Oseretsky Test (p<0.05). CONCLUSIONS: The 6-item motor composite of the Brief Form of Bruininks Oseretsky Test was found to be a reliable tool to measure motor performance in Pakistani pre-school children.

RESUMO

AIM: To assess factors associated with the timing of puberty onset (Tanner Stage Breast 2/Genital 2) among adolescents living in an urban slum in Karachi, Pakistan. METHODS: Girls enrolled at 8-10 years (n = 1009) and boys 9-11 years (n = 863) were followed every 6 months from 2006 to 2010. Parametric survival analysis for interval-censored data was used to estimate median age at puberty onset and assess the association between exposures and timing of puberty onset. RESULTS: The overall median age at Tanner Stage Breast 2 (AAB2) was 10.1 years (95% CI: 10.1; 10.5), and the median age at Tanner Stage Genital 2 (AAG2) was 10.1 years (95% CI: 10.1; 10.6). Stunting delayed AAB2 1 year and AAG2 about 6 months when compared to non-stunted peers. In the multivariable model, after adjusting for age at enrolment, stunting, thinness and vitamin A deficiency (VAD) were significantly associated with delayed AAB2, while stunting and anaemia were significantly associated with delayed AAG2. CONCLUSION: Among adolescents living in the Karachi slum, stunting and highly prevalent anaemia delayed AAG2, while stunting, thinness and VAD delayed AAG2. Parental and household factors were not significantly associated with the timing of puberty onset.

RESUMO

BACKGROUND: Different approaches have been adopted in the treatment of anaplastic large cell lymphoma (ALCL); there is a lack of consensus with regard to standard treatment. Because of paucity of data from low and middle-income countries, we reviewed the clinical features and treatment outcomes of children with ALCL. METHODS: All ALCL patients under 16 years of age diagnosed from 2005 to 2015 at Aga Khan University Hospital and The Indus Hospital were identified. Clinical features and treatment outcomes were analyzed. RESULTS: Thirty-two (n=32) patients met the inclusion criteria. Cervical Lymphadenopathy was the most common presentation (34.3%, n=11). Advanced disease was seen in 68.7% (n=22) (stages III and IV). Fourteen (42.4%) were treated on ALCL-99, 30.3% (n=10) on multicenter protocol-842 regimen, 9% (n=3) on adriamycin-prednisolone-oncovin (doxorubicin, prednisone, vincristine) regimen, and 16% (n=5) were treatment abandonments. Five-year overall survival was 70.6% (95% confidence interval: 47.8%-84.9%), and 5-year event-free survival (EFS) considering treatment abandonment and death as an event was 52.3 % (95% confidence interval: 23.5%-74.8%). CONCLUSIONS: Significant therapy-related mortality (27.7%) was observed. Treatment abandonment and therapy-related toxicity were the major barriers for better outcomes. However, less intensive outpatient regimens, such as adriamycin-prednisolone-oncovin regimen, may decrease the number of hospitalizations, hence reducing treatment abandonment in the low and middle-income country.

RESUMO

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. Subgroup analysis demonstrated a significantly decreased mitral E/A ratio in children whose mothers were on medications as compared to those on dietary control (median [IQR] = 1.7 [1.6-1.9] and 1.56 [1.4-1.7], respectively, p = 0.02), and a higher cIMT in children whose mothers were on medication as compared to controls (0.48 [0.44-0.52] and 0.46 [0.44-0.50], respectively, p = 0.03). CONCLUSION: In utero exposure to uncontrolled maternal diabetes has an effect on the cardiovascular structure and function in children aged 2-5 years. However, future work requires long-term follow-up from fetal to adult life to assess these changes over the life course.

RESUMO

OBJECTIVES: 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. METHODS: In a community-based, observational, longitudinal study in a peri-urban settlement of Karachi, Pakistan, we compared the size of the exchangeable zinc pools (EZPs) 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. RESULTS: No significant difference was detected in the mean (±standard deviation) EZP between SGA and AGA infants at birth, with values of 9.8 ±â€Š3.5 and 10.1 ±â€Š4.1 mg/kg, respectively (P = 0.86), or at 6 months. Longitudinal EZP measurements demonstrated a significant decline in EZP relative to body weight in both groups at 6 months (P < 0.001). Mean EZP (adjusted for body weight) size at birth for the combined Pakistani groups was significantly lower than AGA infants at birth in the United States (P = 0.017). CONCLUSIONS: These results did not support a difference in zinc endowment between SGA and AGA Pakistani infants. They, however, do suggest lower in utero zinc transfer to the fetus in a setting where poor maternal nutritional status may confer a high susceptibility to postnatal zinc deficiency.

RESUMO

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 prevent stillbirths and reduce associated morbidity.

RESUMO

BACKGROUND: Afghanistan has made considerable gains in improving maternal and child health and survival since 2001. However, socioeconomic and regional inequities may pose a threat to reaching universal coverage of health interventions and further health progress. We explored coverage and socioeconomic inequalities in key life-saving reproductive, maternal, newborn and child health (RMNCH) interventions at the national level and by region in Afghanistan. We also assessed gains in child survival through scaling up effective community-based interventions across wealth groups. METHODS: Using data from the Afghanistan Multiple Indicator Cluster Survey (MICS) 2010/11, we explored 11 interventions that spanned all stages of the continuum of care, including indicators of composite coverage. Asset-based wealth quintiles were constructed using standardised methods, and absolute inequalities were explored using wealth quintile (Q) gaps (Q5-Q1) and the slope index of inequality (SII), while relative inequalities were assessed with ratios (Q5/Q1) and the concentration index (CIX). The lives saved tool (LiST) modeling used to estimate neonatal and post-neonatal deaths averted from scaling up essential community-based interventions by 90 % coverage by 2025. Analyses considered the survey design characteristics and were conducted via STATA version 12.0 and SAS version 9.4. RESULTS: Our results underscore significant pro-rich socioeconomic absolute and relative inequalities, and mass population deprivation across most all RMNCH interventions studied. The most inequitable are antenatal care with a skilled attendant (ANCS), skilled birth attendance (SBA), and 4 or more antenatal care visits (ANC4) where the richest have between 3.0 and 5.6 times higher coverage relative to the poor, and Q5-Q1 gaps range from 32 % - 65 %. Treatment of sick children and breastfeeding interventions are the most equitably distributed. Across regions, inequalities were highest in the more urbanised East, West and Central regions of the country, while they were lowest in the South and Southeast. About 7700 newborns and 26,000 post-neonates could be saved by scaling up coverage of community outreach interventions to 90 %, with the most gains in the poorest quintiles. CONCLUSIONS: Afghanistan is a pervasively poor and conflict-prone nation that has only recently experienced a decade of relative stability. Though donor investments during this period have been plentiful and have contributed to rebuilding of health infrastructure in the country, glaring inequities remain. A resolution to scaling up health coverage in insecure and isolated regions, and improving accessibility for the poorest and marginalised populations, should be at the forefront of national policy and programming efforts.

RESUMO

BACKGROUND: Stimulation and nutrition delivered through health programmes at a large scale could potentially benefit more than 200 million young children worldwide who are not meeting their developmental potential. We investigated the feasibility and effectiveness of the integration of interventions to enhance child development and growth outcomes in the Lady Health Worker (LHW) programme in Sindh, Pakistan. METHODS: We implemented a community-based cluster-randomised effectiveness trial through the LHW programme in rural Sindh, Pakistan, with a 2 × 2 factorial design. We randomly allocated 80 clusters (LHW catchments) of children to receive routine health and nutrition services (controls; n=368), nutrition education and multiple micronutrient powders (enhanced nutrition; n=364), responsive stimulation (responsive stimulation; n=383), or a combination of both enriched interventions (n=374). The allocation ratio was 1:20 (ie, 20 clusters per intervention group). The data collection team were masked to the allocated intervention. All children born in the study area between April, 2009, and March, 2010, were eligible for enrolment if they were up to 2·5 months old without signs of severe impairments. Interventions were delivered by LHWs to families with children up to 24 months of age in routine monthly group sessions and home visits. The primary endpoints were child development at 12 and 24 months of age (assessed with the Bayley Scales of Infant and Toddler Development, Third Edition) and growth at 24 months of age. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT007159636. FINDINGS: 1489 mother-infant dyads were enrolled into the study, of whom 1411 (93%) were followed up until the children were 24 months old. Children who received responsive stimulation had significantly higher development scores on the cognitive, language, and motor scales at 12 and 24 months of age, and on the social-emotional scale at 12 months of age, than did those who did not receive the intervention. Children who received enhanced nutrition had significantly higher development scores on the cognitive, language, and social-emotional scales at 12 months of age than those who did not receive this intervention, but at 24 months of age only the language scores remained significantly higher. We did not record any additive benefits when responsive stimulation was combined with nutrition interventions. Responsive stimulation effect sizes (Cohen's d) were 0·6 for cognition, 0·7 for language, and 0·5 for motor development at 24 months of age; these effect sizes were slightly smaller for the combined intervention group and were low to moderate for the enhanced nutrition intervention alone. Children exposed to enhanced nutrition had significantly better height-for-age Z scores at 6 months (p<0·0001) and 18 months (p=0·02) than did children not exposed to enhanced nutrition. Longitudinal analysis showed a small benefit to linear growth from enrolment to 24 months (p=0·026) in the children who received the enhanced nutrition intervention. INTERPRETATION: The responsive stimulation intervention can be delivered effectively by LHWs and positively affects development outcomes. The absence of a major effect of the enhanced nutrition intervention on growth shows the need for further analysis of mediating variables (eg, household food security status) that will help to optimise future nutrition implementation design.

RESUMO

Progress in newborn survival has been slow, and even more so for reductions in stillbirths. To meet Every Newborn targets of ten or fewer neonatal deaths and ten or fewer stillbirths per 1000 births in every country by 2035 will necessitate accelerated scale-up of the most effective care targeting major causes of newborn deaths. We have systematically reviewed interventions across the continuum of care and various delivery platforms, and then modelled the effect and cost of scale-up in the 75 high-burden Countdown countries. Closure of the quality gap through the provision of effective care for all women and newborn babies delivering in facilities could prevent an estimated 113,000 maternal deaths, 531,000 stillbirths, and 1·325 million neonatal deaths annually by 2020 at an estimated running cost of US$4·5 billion per year (US$0·9 per person). Increased coverage and quality of preconception, antenatal, intrapartum, and postnatal interventions by 2025 could avert 71% of neonatal deaths (1·9 million [range 1·6-2·1 million]), 33% of stillbirths (0·82 million [0·60-0·93 million]), and 54% of maternal deaths (0·16 million [0·14-0·17 million]) per year. These reductions can be achieved at an annual incremental running cost of US$5·65 billion (US$1·15 per person), which amounts to US$1928 for each life saved, including stillbirths, neonatal, and maternal deaths. Most (82%) of this effect is attributable to facility-based care which, although more expensive than community-based strategies, improves the likelihood of survival. Most of the running costs are also for facility-based care (US$3·66 billion or 64%), even without the cost of new hospitals and country-specific capital inputs being factored in. The maximum effect on neonatal deaths is through interventions delivered during labour and birth, including for obstetric complications (41%), followed by care of small and ill newborn babies (30%). To meet the unmet need for family planning with modern contraceptives would be synergistic, and would contribute to around a halving of births and therefore deaths. Our analysis also indicates that available interventions can reduce the three most common cause of neonatal mortality--preterm, intrapartum, and infection-related deaths--by 58%, 79%, and 84%, respectively.

RESUMO

Global mortality in children younger than 5 years has fallen substantially in the past two decades from more than 12 million in 1990, to 6·9 million in 2011, but progress is inconsistent between countries. Pneumonia and diarrhoea are the two leading causes of death in this age group and have overlapping risk factors. Several interventions can effectively address these problems, but are not available to those in need. We systematically reviewed evidence showing the effectiveness of various potential preventive and therapeutic interventions against childhood diarrhoea and pneumonia, and relevant delivery strategies. We used the Lives Saved Tool model to assess the effect on mortality when these interventions are applied. We estimate that if implemented at present annual rates of increase in each of the 75 Countdown countries, these interventions and packages of care could save 54% of diarrhoea and 51% of pneumonia deaths by 2025 at a cost of US$3·8 billion. However, if coverage of these key evidence-based interventions were scaled up to at least 80%, and that for immunisations to at least 90%, 95% of diarrhoea and 67% of pneumonia deaths in children younger than 5 years could be eliminated by 2025 at a cost of $6·715 billion. New delivery platforms could promote equitable access and community platforms are important catalysts in this respect. Furthermore, several of these interventions could reduce morbidity and overall burden of disease, with possible benefits for developmental outcomes.

RESUMO

Maternal undernutrition contributes to 800,000 neonatal deaths annually through small for gestational age births; stunting, wasting, and micronutrient deficiencies are estimated to underlie nearly 3·1 million child deaths annually. Progress has been made with many interventions implemented at scale and the evidence for effectiveness of nutrition interventions and delivery strategies has grown since The Lancet Series on Maternal and Child Undernutrition in 2008. We did a comprehensive update of interventions to address undernutrition and micronutrient deficiencies in women and children and used standard methods to assess emerging new evidence for delivery platforms. We modelled the effect on lives saved and cost of these interventions in the 34 countries that have 90% of the world's children with stunted growth. We also examined the effect of various delivery platforms and delivery options using community health workers to engage poor populations and promote behaviour change, access and uptake of interventions. Our analysis suggests the current total of deaths in children younger than 5 years can be reduced by 15% if populations can access ten evidence-based nutrition interventions at 90% coverage. Additionally, access to and uptake of iodised salt can alleviate iodine deficiency and improve health outcomes. Accelerated gains are possible and about a fifth of the existing burden of stunting can be averted using these approaches, if access is improved in this way. The estimated total additional annual cost involved for scaling up access to these ten direct nutrition interventions in the 34 focus countries is Int$9·6 billion per year. Continued investments in nutrition-specific interventions to avert maternal and child undernutrition and micronutrient deficiencies through community engagement and delivery strategies that can reach poor segments of the population at greatest risk can make a great difference. If this improved access is linked to nutrition-sensitive approaches--ie, women's empowerment, agriculture, food systems, education, employment, social protection, and safety nets--they can greatly accelerate progress in countries with the highest burden of maternal and child undernutrition and mortality.

RESUMO

Globally, Pakistan has the third highest burden of maternal, fetal, and child mortality. It has made slow progress in achieving the Millennium Development Goals (MDGs) 4 and 5 and in addressing common social determinants of health. The country also has huge challenges of political fragility, complex security issues, and natural disasters. We undertook an in-depth analysis of Pakistan's progress towards MDGs 4 and 5 and the principal determinants of health in relation to reproductive, maternal, newborn, and child health and nutrition. We reviewed progress in relation to new and existing public sector programmes and the challenges posed by devolution in Pakistan. Notwithstanding the urgent need to tackle social determinants such as girls' education, empowerment, and nutrition in Pakistan, we assessed the effect of systematically increasing coverage of various evidence-based interventions on populations at risk (by residence or poverty indices). We specifically focused on scaling up interventions using delivery platforms to reach poor and rural populations through community-based strategies. Our model indicates that with successful implementation of these strategies, 58% of an estimated 367,900 deaths (15,900 maternal, 169,000 newborn, 183,000 child deaths) and 49% of an estimated 180,000 stillbirths could be prevented in 2015.

RESUMO

BACKGROUND: Maternal undernutrition is a direct risk factor for infant growth faltering. OBJECTIVES: We evaluated the effect of postnatal balanced energy protein (BEP) supplementation in lactating women and azithromycin (AZ) in infants on infant growth outcomes. METHODS: A randomized controlled superiority trial of lactating mother-newborn dyads was conducted in Karachi, Pakistan. Mothers intending to breastfeed their newborns with mid-upper arm circumference of <23 cm and live infants between 0 and 6 d of life were randomly assigned to 1 of 3 arms in a 1:1:1 ratio. Lactating mothers in the control arm received standard-of-care counseling on exclusive breastfeeding, nutrition, infant immunization, and health promotion plus iron-folate supplementation until the infant was 6 mo old. In intervention arm 1, mothers additionally received two 75-g sachets of BEP per day. In intervention arm 2, along with the standard-of-care and BEP to the mother, the infant also received 1 dose of azithromycin (20 mg/kg) at the age of 42 d . The primary outcome was infant length velocity at 6 mo. The total sample size was 957 (319 in each arm). RESULTS: From 1 August, 2018 to 19 May, 2020, 319 lactating mother-newborn dyads were randomly assigned in each arm, and the last follow-up was completed on 20 November, 2020. The mean difference in length velocity (cm/mo) between BEP alone and control was 0.01 (95% confidence interval [CI]: -0.03, 0.06), BEP plus AZ and control was 0.08 (95% CI: 0.03, 0.13), and between BEP + AZ and BEP alone was 0.06 (95% CI: 0.01, 0.11). There were 1.46% (14/957) infant deaths in the trial, and 17.9% (171/957) nonfatal events (injectable treatment and/or hospitalizations) were recorded. CONCLUSIONS: Postnatal maternal BEP supplementation and infant AZ administration could modestly improve infant growth outcomes at 6 mo, suggesting potential benefits in simultaneously addressing maternal and infant undernutrition. This trial was registered at clinicaltrials.gov as NCT03564652.

RESUMO

Background: Globally, 36.5% of pregnancies are affected by anemia, particularly in low-and middle-income countries, posing significant risks to maternal and perinatal health. In rural Pakistan, 44.3% of pregnant women suffer from iron deficiency, contributing to the high prevalence of anemia. Limited accessibility to antenatal care exacerbates the challenge, necessitating innovative solutions. This study assessed a midwife-led continuity of care model, utilizing intravenous (IV) iron therapy for the management of anemia in Karachi, Pakistan. Methods: We performed a retrospective analysis of data from a prospective cohort study conducted in two primary healthcare facilities, which employed a community midwife (CMW)-led continuity of care model for antenatal care, including IV iron therapy. We extracted data from February 2021 to March 2022 for women who were diagnosed with anemia based on hemoglobin (Hb) levels, categorized as mild (10.0 to 10.9 g/dL), moderate (7.0 to 9.9 g/dL), or severe (less than 7.0 g/dL). Assessment occurred at the initial antenatal care (ANC) visit to establish baseline anemia severity, and approximately 2 weeks after intravenous (IV) iron therapy administration to evaluate post-treatment changes were considered. Results: We enrolled 114 pregnant women, where the majority presented with moderate (88.6%) anemia. After IV iron treatment, 48.5% improved to normal-mild levels, while 50% remained unchanged. Severe anemia affected 10.5% at baseline; 42% shifted to moderate and 50% to normal-mild post-treatment, with one remaining unchanged (p < 0.001). Among women enrolled in the first and second trimesters, severe anemia improved to normal-mild (50%) and moderate levels (50%) (pre-treatment: n = 10, post-treatment: n = 0), and moderate anemia decreased by 48% (pre-treatment: n = 92, post-treatment: n = 47). Conclusion: Our midwife-led model of care demonstrated an improvement in iron levels among pregnant women. The model addressed the challenges of anemia prevalence in Pakistan and underscored the significance of empowering front-line healthcare providers, such as community midwives (CMWs) for managing these common conditions.
