The articles in this collection examine the evidence and the thinking that form the basis of the new global strategy.
In this seminar Professor Kevin Marsh describes how knowledge of immunity to malaria in humans has developed over the past thirty years and what impact this has for future research.
Hypertension Education Intervention with Ugandan Nurses Working in Hospital Outpatient Clinic: A Pilot Studyby Nicola McHugh
This pilot study demonstrated that nurses’ knowledge, skills, and attitudes could be significantly improved with a multimodal education program implemented in a low resource environment.
The nine-article special issue, titled Newborn Health in Uganda, details results of a community randomized trial, the Uganda Newborn Study (UNEST), which evaluated an integrated care package linking homes, clinics and hospitals and involving visits during pregnancy and the postnatal period at home by a designated member of the village health team. The UNEST results demonstrate that these home visits in pregnancy and soon after delivery were possible to achieve, and that life-saving behaviors could be improved by this interaction. UNEST was influenced by the previously published neonatal survival series in the Lancet which identified cost-effective interventions that could prevent the majority of deaths in the newborn period.
Treatment of Infections in Young Infants in Low- and Middle-Income Countries: A Systematic Review and Meta-analysis of Frontline Health Worker Diagnosis and Antibiotic Accessby Lee ACC et al
Inadequate illness recognition and access to antibiotics contribute to high case fatality from infections in young infants (<2 months) in low- and middle-income countries (LMICs). This study aimed to address three questions regarding access to treatment for young infant infections in LMICs: (1) Can frontline health workers accurately diagnose possible bacterial infection (pBI)?; (2) How available and affordable are antibiotics?; (3) How often are antibiotics procured without a prescription?
This series of five papers assesses and summarizes information from relevant systematic reviews on the impact of various approaches to improve the quality of care for women and newborns.
Use of antenatal corticosteroids and tocolytic drugs in preterm births in 29 countries: an analysis of the WHO Multicountry Survey on Maternal and Newborn Healthby Vogel JP et al
Despite the global burden of morbidity and mortality associated with preterm birth, little evidence is available for use of antenatal corticosteroids and tocolytic drugs in preterm births in low-income and middle-income countries. The authors in thsi study analysed data from the WHO Multicountry Survey on Maternal and Newborn Health (WHOMCS) to assess coverage for these interventions in preterm deliveries. Use of interventions was generally poor, despite evidence for their benefit for newborn babies. A substantial proportion of antenatal corticosteroid use occurred at gestational ages at which benefit is controversial, and use of less effective or potentially harmful tocolytic drugs was common. Implementation research and contextualised health policies are needed to improve drug availability and increase compliance with best obstetric practice.
Worldwide, 250,000–280,000 women die during pregnancy and childbirth every year and an estimated 6.55 million children die under the age of five. The majority of maternal deaths occur during or immediately after childbirth, while 43% of child death occurs during the first 28 days of life. However, the progress in limiting these has been slow and sporadic. In this supplement of five papers, teh authors aim to systematically assess and summarize essential interventions for reproductive, maternal, newborn and child health from relevant systematic reviews.
This thematic series of eight papers provides an overview on infectious diseases of poverty and integrated community-based interventions, describes the analytical framework and the methodology used to guide the systematic reviews, reports findings for the effectiveness of community-based interventions for the prevention and control of helminthic NTDs, non-helminthic NTDs, malaria, HIV/AIDS and tuberculosis and proposes a way forward. While previous reviews focus on process and effectiveness of integrated community-based interventions under real life field conditions, this series of papers evaluates the efficacy of such interventions with respect to disease or prevention outcomes.
The current difficulties in keeping systematic reviews up to date leads to considerable inaccuracy, hampering the translation of knowledge into action. Incremental advances in conventional review updating are unlikely to lead to substantial improvements in review currency. A new approach is needed. The authors propose living systematic review as a contribution to evidence synthesis that combines currency with rigour to enhance the accuracy and utility of health evidence.
Psychosocial Interventions for Perinatal Common Mental Disorders Delivered by Providers Who Are Not Mental Health Specialists in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysisby Jai K Das
Perinatal common mental disorders (PCMDs) are a major cause of disability among women. Psychosocial interventions are one approach to reduce the burden of PCMDs. Working with care providers who are not mental health specialists, in the community or in antenatal health care facilities, can expand access to these interventions in low-resource settings. The authors in this study assessed effects of such interventions compared to usual perinatal care, as well as effects of interventions based on intervention type, delivery method, and timing.
Black ethnic groups have a higher breast cancer mortality than Whites. American studies have identified variations in tumour biology and unequal health-care access as causative factors. This study compared tumour pathology, treatment and outcomes in three ethnic groups in young breast cancer patients treated in the United Kingdom and concluded that despite equal access to health care, young Black women in the United Kingdom have a significantly poorer outcome than White patients. Black ethnicity is an independent risk factor for reduced DRFS particularly in ER-positive patients.
E-health has become a burgeoning field in which health professionals and health consumers create and seek information. E-health refers to internet-based health care and information delivery and seeks to improve health service locally, regionally and worldwide. E-sexual health presents new opportunities to provide online sexual health services irrespective of gender, age, sexual orientation and location. This paper used the dimensions of the RE-AIM model (reach, efficacy, adoption, implementation and maintenance) as a guiding principle to discuss potentials of E-health in providing and accessing sexual health services.
The recent BMC Public Health supplement “The Lives Saved Tool in 2013: new capabilities and applications” has been published. The series comprise of 30 papers focusing on various domains of maternal child health with a special focus on the interventions reviewed for the prevention and management of childhood diarrhea and penumonia.
This systematic review of the current evidence assessed the effectiveness of food fortification with single micronutrients (iron, folic acid, vitamin A, vitamin D, iodine, zinc) as well as MMN when compared with no fortification on the health and nutrition of women and children.
Risk of Early-Onset Neonatal Infection with Maternal Infection or Colonization: A Global Systematic Review and Meta-Analysisby Jai K Das
Neonatal infections cause a significant proportion of deaths in the first week of life, yet little is known about risk factors and pathways of transmission for early-onset neonatal sepsis globally. This review aimed to estimate the risk of neonatal infection (excluding sexually transmitted diseases [STDs] or congenital infections) in the first seven days of life among newborns of mothers with bacterial infection or colonization during the intrapartum period.
Effect of Household-Based Drinking Water Chlorination on Diarrhoea among Children under Five in Orissa, India: A Double-Blind Randomised Placebo-Controlled Trialby Jai K Das
Boiling, disinfecting, and filtering water within the home can improve the microbiological quality of drinking water among the hundreds of millions of people who rely on unsafe water supplies. However, the impact of these interventions on diarrhoea is unclear. The aim of this study was to measure the effect of in-home water disinfection on diarrhoea among children under five.
Changes in Association between Previous Therapeutic Abortion and Preterm Birth in Scotland, 1980 to 2008: A Historical Cohort Studyby Jai K Das
The authors in this study hypothesized that the association between previous abortion and the risk of preterm first birth changed in Scotland between 1 January 1980 and 31 December 2008.
Health data include many gaps, particularly relating to poorer areas of the world, so complex estimation techniques are needed to get overall global pictures. Estimates of population health, however, carry their own uncertainties and may be flawed in some instances. Here we present a range of reflections on the Global Burden of Disease 2010 estimates, highlighting their strengths as well as challenges for potential users. In the long term, there can be no substitute for properly counting and accounting for all the world's citizens, so that complex estimation techniques are not needed.
Adherence to antiretroviral therapy among HIV infected children measured by caretaker report, medication return, and drug level in Dar Es Salaam, Tanzaniaby Jai K Das
Adherence to antiretroviral drugs in the treatment of paediatric HIV infection is complicated because of many factors including stigma and drug intake logistics. It is therefore important to identify children with non-adherence in order to intervene before they become at risk of developing treatment failure or drug resistance. The aim of this study was to determine the level of adherence to antiretroviral therapy (ART), measured by caretaker report, medication return and nevirapine plasma concentration.
Maternal and child undernutrition Series was launched in The Lancet in 2008. Five years after the initial series, the issue was re-evaluated including the growing problems of overweight and obesity for women and children, and their consequences in low-income and middle-income countries. Many of these countries are said to have the double burden of malnutrition: continued stunting of growth and deficiencies of essential nutrients along with the emerging issue of obesity. The national progress in nutrition programmes and international efforts toward previous recommendations were also evaluated
The Lancet publishes a special themed issue to coincide with the third Women Deliver conference in Kuala Lumpur, Malaysia on May 28–30, 2013. Women Deliver brings together voices from around the world to generate political commitment and resource investments to improve the health and well-being of girls and women and achieve universal access to reproductive health. The studies published in The Lancet's themed issue use different methods to show the multidimensional nature of reproductive health and the influence of social determinants and health systems.
Women with preeclampsia (PEC) and gestational hypertension (GH) exhibit insulin resistance during pregnancy, independent of obesity and glucose intolerance. The authors in this paper aim to determine whether women with PEC or GH during pregnancy have an increased risk of developing diabetes after pregnancy, and whether the presence of PEC/GH in addition to gestational diabetes (GDM) increases the risk of future (postpartum) diabetes.
The Lancet Series on Childhood Pneumonia and Diarrhoea, led by Aga Khan University, Pakistan, provides evidence for integrated control efforts for childhood pneumonia and diarrhoea.The series of four papers assesses the global burden of these two illnesses and identifies a set of highly cost-effective interventions that can prevent most diarrhoea deaths and nearly two thirds of pneumonia deaths by 2025, if delivered at scale. It also highlights the findings from consultations with several hundred frontline workers in high-burden countries and explores the barriers and enablers they face in dealing with these two diseases and potential ways forward. The final paper represents a call to action and discusses the global and country-level remedies needed to eliminate preventable deaths from these illnesses by 2025.
Despite published guidance on writing the abstract in the PRISMA Statement guiding the reporting of systematic reviews in general and elsewhere, evaluations show that reporting of systematic reviews in journal and conference abstracts is poor. Teh authors developed consensus-based reporting guidelines as an extension to the PRISMA Statement on good reporting of systematic reviews and meta-analyses in abstracts.
There have been significant improvements in the performance of the Expanded Programme on Immunization (EPI) in Africa since its inception in 1974. However, there exist wide inter- and intra-country differences.
