A risk prediction model for the assessment and triage of women with hypertensive disorders of pregnancy in low-resourced settings: the miniPIERS (Pre-eclampsia Integrated Estimate of RiSk) multi-country prospective cohort study.

BACKGROUND: Pre-eclampsia/eclampsia are leading causes of maternal mortality and morbidity, particularly in low- and middle- income countries (LMICs). We developed the miniPIERS risk prediction model to provide a simple, evidence-based tool to identify pregnant women in LMICs at increased risk of death or major hypertensive-related complications. METHODS AND FINDINGS: From 1 July 2008 to 31 March 2012, in five LMICs, data were collected prospectively on 2,081 women with any hypertensive disorder of pregnancy admitted to a participating centre. Candidate predictors collected within 24 hours of admission were entered into a step-wise backward elimination logistic regression model to predict a composite adverse maternal outcome within 48 hours of admission. Model internal validation was accomplished by bootstrapping and external validation was completed using data from 1,300 women in the Pre-eclampsia Integrated Estimate of RiSk (fullPIERS) dataset. Predictive performance was assessed for calibration, discrimination, and stratification capacity. The final miniPIERS model included: parity (nulliparous versus multiparous); gestational age on admission; headache/visual disturbances; chest pain/dyspnoea; vaginal bleeding with abdominal pain; systolic blood pressure; and dipstick proteinuria. The miniPIERS model was well-calibrated and had an area under the receiver operating characteristic curve (AUC ROC) of 0.768 (95% CI 0.735-0.801) with an average optimism of 0.037. External validation AUC ROC was 0.713 (95% CI 0.658-0.768). A predicted probability ≥25% to define a positive test classified women with 85.5% accuracy. Limitations of this study include the composite outcome and the broad inclusion criteria of any hypertensive disorder of pregnancy. This broad approach was used to optimize model generalizability. CONCLUSIONS: The miniPIERS model shows reasonable ability to identify women at increased risk of adverse maternal outcomes associated with the hypertensive disorders of pregnancy. It could be used in LMICs to identify women who would benefit most from interventions such as magnesium sulphate, antihypertensives, or transportation to a higher level of care.

Alma-Ata: Rebirth and Revision 6 Interventions to address maternal, newborn, and child survival: what difference can integrated primary health care strategies make?

Several recent reviews of maternal, newborn, and child health (MNCH) and mortality have emphasised that a large range of interventions are available with the potential to reduce deaths and disability. The emphasis within MNCH varies, with skilled care at facility levels recommended for saving maternal lives and scale-up of community and household care for improving newborn and child survival. Systematic review of new evidence on potentially useful interventions and delivery strategies identifies 37 key promotional, preventive, and treatment interventions and strategies for delivery in primary health care. Some are especially suitable for delivery through community support groups and health workers, whereas others can only be delivered by linking community-based strategies with functional first-level referral facilities. Case studies of MNCH indicators in Pakistan and Uganda show how primary health-care interventions can be used effectively. Inclusion of evidence-based interventions in MNCH programmes in primary health care at pragmatic coverage in these two countries could prevent 20-30% of all maternal deaths (up to 32% with capability for caesarean section at first-level facilities), 20-21% of newborn deaths, and 29-40% of all postneonatal deaths in children aged less than 5 years. Strengthening MNCH at the primary health-care level should be a priority for countries to reach their Millennium Development Goal targets for reducing maternal and child mortality.

Maternal health and survival in Pakistan: issues and options.

Although its measurement may be difficult, the maternal mortality ratio (MMR) is a key indicator of maternal health globally. In Pakistan each year over five million women become pregnant, and of these 700,000 (15% of all pregnant women) are likely to experience some obstetrical and medical complications. An estimated 30,000 women die each year from pregnancy-related causes, and the most recent estimates indicate that the MMR is 276 per 100,000 births annually. In this review, we describe the status of maternal health and survival in Pakistan and place it in its wider context of key determinants. We draw attention to the economic and social vulnerability of pregnant women, and stress the importance of concomitant broader strategies, including poverty reduction and women's empowerment. Undernutrition for girls, early marriage, and high fertility rates coupled with unmet needs for contraception are important determinants of maternal ill health in Pakistan. Our review also examines factors influencing the under-utilization of maternal health services among Pakistani women, such as the lack of availability of skilled care providers and poor quality services. Notwithstanding these observations, there are evidence-based interventions available that, if implemented at scale, could make important contributions towards reducing the burden of maternal mortality in Pakistan.

Loading dose of magnesium sulphate versus standard regime for prophylaxis of pre-eclampsia.

OBJECTIVE: To determine the efficacy of single dose of magnesium sulphate versus the standard Pritchard regime in the management of pre-eclampsia. STUDY DESIGN: Quasi-experimental study. PLACE AND DURATION OF STUDY: Jinnah Postgraduate Medical Centre, Karachi, from January 2004 to January 2006. METHODOLOGY: All women with severe pre-eclampsia and impending eclampsia were included in the study. Patients with pregnancy induced hypertension and mild to moderate pre-eclampsia were excluded. From the 100 women included in the study, after matching for age, parity and gestational age, 50 were given only bolus dose of magnesium sulphate and 50 were given the standard regime. They were observed for one week for the number of convulsions. Fisher's exact test and Chi-square test were used to analyze results. RESULTS: There was no significant difference in the two groups in term of occurrence of seizures, one patient developed fit with Pritchard regimen. The rate of caesarean section was lower in group A, 12% versus 30% in group B (p=0.05). There was no significant difference in perinatal outcome in either group (82% live births in group A versus 72% amongst group B (p=0.2). Few side effects like vomiting, dizziness and irritation at the site of injection were observed when standard treatment was used. Single dose treatment was also found to be cost-effective costing Pak Rs. 45 (US $ 0.56) as compared to Pak Rs. 195 (US $ 2.4) in control group. No maternal death was observed in either group. CONCLUSION: Having the equal effectiveness, ease of monitoring and cost-effectiveness, single loading dose of magnesium sulphate is preferable over the standard regime in the management of pre-eclampsia as a prophylactic measure for prevention of seizure.

Review of nutrition guidelines relevant for adolescents in low- and middle-income countries.

The economic and social well-being of any country will one day depend on its current adolescent population. To provide a good foundation for healthy adolescent development, healthy diet, along with physical activity and adequate nutrients, is necessary. Therefore, addressing the nutrition needs of adolescents could be an important step toward breaking the vicious cycle of intergenerational malnutrition, chronic diseases, and poverty. These problems could be addressed with timely recognition and appropriately delivered interventions. Our aim here is to review the existing guidelines on various aspects of nutrition interventions for adolescents and young women. We review all of the major existing guidelines on adolescent nutrition. We were able to find 18 guideline bodies that covered some form of nutritional advice in guidelines that targeted adolescents. Although the guidelines that focus specifically on this age group are limited in scope, we also extrapolated recommendations from guidelines focused on adults, women of reproductive age, and pregnant women, which were based on evidence that included populations of adolescent girls. We were able to extract and synthesize specific directives for nutrition in adolescents, macro- and micronutrient supplementation, exercise, obesity, and nutrition during preconception, pregnancy, and the postconception period.

Prevalence of hepatitis B and C: a Jinnah Postgraduate Medical Centre experience.

AIM: To determine the prevalence of carriers of hepatitis B and C viruses among the obstetrical and gynecological population, the incidence of vertical transmission in obstetrical patients and to ascertain the risk factors associated with their transmission. METHODS: We conducted a prospective study over a 1-year period, from 1 January to 31 December 2005, comprising of an obstetrical population of 5902 deliveries and 548 major gynecology surgery patients. The study population was recruited by simple convenient sampling at Unit-I, Department of Obstetrics and Gynecology, Jinnah Postgraduate Medical Centre, Karachi, Pakistan. Booked obstetrical and major gynecological surgical patients were routinely screened by Enzyme Immunoassay for hepatitis B surface antigen (HbsAg) and anti-hepatitis C antibodies (anti-HCV) on venous blood samples. Liver function and carrier profile tests were performed on mothers who were positive for HBsAg. Babies of mothers with HbsAg were tested at birth for both HbsAg and HbeAg. RESULTS: Hepatitis B was detected in 275 pregnant women (4.6%) and in 70 (12%) gynecological patients. Hepatitis C was detected in 108 (1.8%) pregnant women and in 89 (16%) gynecological patients. Babies born to mothers with HBV or HCV infections tested negative. Four gynecological patients tested positive for both HBV and HCV infections. Unsafe surgery, injections and inadequately screened blood transfusions were the main underlying causes of infection. CONCLUSION: Routine screening of the obstetrical population detected more cases of HBV infection than HCV, whereas HCV was more prevalent in the gynecological population, emphasizing the need for safe medical practices and patient education.
