The Effect of Community-Based Prevention and Care on Ebola Transmission in Sierra Leone.

OBJECTIVES: To examine the acceptability, use, effects on early isolation, and contribution to Ebola virus disease (EVD) transmission of Community Care Centers (CCCs), which were rapidly deployed in Sierra Leone during an accelerated phase of the 2014-2015 EVD epidemic. METHODS: Focus group discussions, triads, and key informant interviews assessed acceptability of the CCCs. Facility registers, structured questionnaires, and laboratory records documented use, admission, and case identification. We estimated transmission effects by comparing time between symptom onset and isolation at CCCs relative to other facilities with the national Viral Hemorrhagic Fever data set. RESULTS: Between November 2014 and January 2015, 46 CCCs were operational. Over 13 epidemic weeks, 6129 patients were triaged identifying 719 (12%) EVD suspects. Community acceptance was high despite initial mistrust. Nearly all patients presented to CCCs outside the national alert system. Isolation of EVD suspects within 4 days of symptoms was higher in CCCs compared with other facilities (85% vs 49%; odds ratio = 6.0; 95% confidence interval = 4.0, 9.1), contributing to a 13% to 32% reduction in the EVD reproduction number (Ro). CONCLUSIONS: Community-based approaches to prevention and care can reduce Ebola transmission.

Post-crisis Zimbabwe's innovative financing mechanisms in the social sectors: a practical approach to implementing the new deal for engagement in fragile states.

BACKGROUND: Donor engagement in transitional settings, complex emergencies and fragile states is increasing. Neither short-term humanitarian aid nor traditional development financing are well adapted for such environments. Multi-donor trust funds, in their current form, can be unwieldy and subject to long delays in initiation and work best when national governments are already strong. We reviewed the aid modalities used in Zimbabwe through the period of crisis, 2008-2012 and their results and implications. Literature review and case experience was utilised. DISCUSSION: By focusing on working with line ministries in non-contested sectors to determine local priorities rather than following global prescriptions, pooling funds to achieve scale rather than delivering through fragmented projects, and building on national systems and capacities rather than setting up parallel mechanisms, the Transition Fund Model employed in Zimbabwe by UNICEF and partners in partnership with the Inclusive Government was able to achieve important results in health, education, social support and water services in a challenging setting. In addition, forums for collaboration were developed that provided a platform for further action. The initial emphasis on service delivery diffused much of the political delicateness that impeded progress in other sectors. The Zimbabwean experience may provide a model of innovative financing for countries facing similar circumstances. Such models may represent a new practical application of the Paris Principles, consistent with the major tenets of the 2011 New Deal for Engagement in Fragile States agreed in Busan. As we approach the Millennium Development Goal deadline, an over-arching, mutli-sectoral and independent evaluation of this approach is recommended in order to validate findings and assess broader replicability of this approach.

Transplantation of PSC-derived myogenic progenitors counteracts disease phenotypes in FSHD mice.

Facioscapulohumeral muscular dystrophy (FSHD) is a genetically dominant progressive myopathy caused by improper silencing of the DUX4 gene, leading to fibrosis, muscle atrophy, and fatty replacement. Approaches focused on muscle regeneration through the delivery of stem cells represent an attractive therapeutic option for muscular dystrophies. To investigate the potential for cell transplantation in FSHD, we have used the doxycycline-regulated iDUX4pA-HSA mouse model in which low-level DUX4 can be induced in skeletal muscle. We find that mouse pluripotent stem cell (PSC)-derived myogenic progenitors engraft in muscle actively undergoing DUX4-mediated degeneration. Donor-derived muscle tissue displayed reduced fibrosis and importantly, engrafted muscles showed improved contractile specific force compared to non-transplanted controls. These data demonstrate the feasibility of replacement of diseased muscle with PSC-derived myogenic progenitors in a mouse model for FSHD, and highlight the potential for the clinical benefit of such a cell therapy approach.

Introducing a sector-wide pooled fund in a fragile context: mixed-methods evaluation of the health transition fund in Zimbabwe.

INTRODUCTION: Aid effectiveness and improving its impact is a central policy matter for donors and international organisations. Pooled funding is a mechanism, whereby donors provide financial contributions towards a common set of broad objectives by channelling finance through one instrument. The results of pooled funds as an aid mechanism are mixed, and there is limited data on both methodology for, and results of, assessment of effectiveness of pooled funding. METHODS: This study adapted a conceptual framework incorporating the Paris Principles of Aid Effectiveness and qualitative methods to assess the performance of the Health Transition Fund (HTF) Zimbabwe. 30 key informant interviews, and 20 focus group discussions were conducted with informants drawn from village to national level. Descriptive secondary data analysis of Demographic Health Surveys, Health Management Information Systems (HMIS) and policy reports complemented the study. RESULTS: The HTF combined the most optimal option to channel external aid to the health sector in Zimbabwe during a period of socioeconomic and political crisis. It produced results quickly and at scale and enhanced coordination and ownership at the national and subnational level. Flexibility in using the funds was a strong feature of the HTF. However, the initiative compromised on the investment in local capacity and systems, since the primary focus was on restoring essential services within a nearly collapsed healthcare system, rather than building long-term capacity. Significant changes in maternal and newborn health outcomes were observed during the HTF implementation in Zimbabwe. CONCLUSION: A framework which can be used to assess pooled funds was adapted and applied. Future assessments could use this or another framework to provide new evidence regarding effectiveness of pool donor funds although the frameworks should be properly tested and adapted in different contexts.

Can religion kill? The association between membership of the Apostolic faith and child mortality in Zimbabwe.

Existing literature has been equivocal about the effect of religion on utilization of health service and health outcomes. While followers of particularized theology hypothesis believe that doctrinal teachings, beliefs and values of religious groups directly influence health access and outcomes, the advocates of the selectivity hypothesis claim that the observed disparities between religious groups mainly reflect differential access to social and human capital which in turn determines health access and outcome rather than religion per se. Using household data from the Zimbabwe Multiple Indicator Monitoring Survey 2009, we find that household heads' affiliation with apostolic faith put children under five years old at greater risk of death compared to other religious groups. This effect remains strong even after controlling for a wide range of socio-economic and demographics characteristics of the households in multivariate logit regressions.

Countdown to 2015: tracking intervention coverage for child survival.

BACKGROUND: The fourth Millennium Development Goal (MDG) calls for a two-thirds' reduction between 1990 and 2015 in deaths of children younger than five years; achieving this will require widespread use of effective interventions, especially in poor countries. We present the first report of the Child Survival Countdown, a worldwide effort to monitor coverage of key child-survival interventions in 60 countries with the world's highest numbers or rates of child mortality. METHODS: In 2005, we developed a profile for each of the 60 countries to summarise information on coverage with essential child survival interventions. The profiles also present information on demographics, nutritional status, major causes of death in children under 5 years of age, and the status of selected health policies. Progress toward the fourth MDG is summarised by comparing the average annual rate of reduction in under-5 mortality in each country with that needed to achieve the goal. The profiles also include a comparison of the proportions of children in the poorest and richest quintiles of the population who received six or more essential prevention interventions. Each country's progress (as measured by defined indicators of intervention coverage) was put into one of three groups created on the basis of international targets: "on track"; "watch and act"; and "high alert". For indicators without targets, arbitrary thresholds for high, middle, and low performance across the 60 countries were used as a basis for categorisation. FINDINGS: Only seven countries are on track to met MDG-4, 39 countries are making some progress, although they need to accelerate the speed, and 14 countries are cause for serious concern. Coverage of the key child survival interventions remains critically low, although some countries have made substantial improvements in increasing the proportion of mothers and children with access to life saving interventions by as much as ten percentage points in 2 years. Children from the poorest families were less likely than those from wealthier families to have received at least six essential prevention interventions. INTERPRETATION: Our results show that tremendous efforts are urgently needed to achieve the MDG for child survival. Profiles for each country show where efforts need to be intensified, and highlight the extent to which prevention interventions are being delivered equitably and reaching poor families. This first report also shows country-specific improvements in coverage and highlights missed opportunities. The "Countdown to 2015" will report on progress every 2 years as a strategy for increasing accountability worldwide for progress in child survival.

Child mortality according to maternal and infant HIV status in Zimbabwe.

BACKGROUND: HIV causes substantial mortality among African children but there is limited data on how this is influenced by maternal or infant infection status and timing. METHODS: Children enrolled in the ZVITAMBO trial were divided into 5 groups: those born to HIV-negative mothers (NE, n = 9510), those born to HIV-positive mothers but noninfected (NI, n = 3135), those infected in utero (IU, n = 381), those infected intrapartum (IP, n = 508), and those infected postnatally (PN, n = 258). Their mortality was estimated. RESULTS: Two-year mortality was 2.9% (NE infants), 9.2% (NI), 67.5% (IU), 65.1% (IP), and 33.2% (PN). Between 8 weeks and 6 months, mortality in IU infants quintupled (from 309 to 1686/1000 c-y). The median time from infection to death was 208, 380, and >500 days for IU, IP, and PN infants, respectively. Among NI children, advanced maternal disease was predictive of mortality. Acute respiratory infection was the major cause of death. CONCLUSIONS: Perinatally infected infants are at particular risk of death between 2 and 6 months: cotrimoxazole prophylaxis and early pediatric HAART should be scaled up. Uninfected infants of infected mothers have at least twice the mortality risk of infants born to uninfected mothers: all HIV-exposed infants should be targeted with child survival interventions. HIV-positive mothers with more advanced disease are not only more likely to infect their infants, but their infants are more likely to die, whether infected or not: provision of antiretroviral treatment to pregnant and lactating women is an urgent need for both mothers and their children.

HIV, syphilis, herpes simplex virus 2, and behavioral surveillance among conflict-affected populations in Yei and Rumbek, southern Sudan.

Little is known about the HIV epidemic in conflict-affected southern Sudan. During 2002-2003, we conducted behavioral and biological surveillance surveys and sequential sampling in antenatal clinics in Yei, Western Equatoria, and Rumbek, Bar-el-Ghazal. HIV prevalence among individuals aged 15-49 years ranged between 0.4% in Rumbek town and 4.4% in Yei town, and among pregnant women between 0.8 and 3.0%, respectively. After the recent peace agreement, targeted prevention programmes are urgently needed to prevent further spread.

Where giving birth is a forecast of death: maternal mortality in four districts of Afghanistan, 1999-2002.

BACKGROUND: Maternal mortality in Afghanistan is uniformly identified as an issue of primary public-health importance. To guide the implementation of reproductive-health services, we examined the numbers, causes, and preventable factors for maternal deaths among women in four districts. METHODS: We did a retrospective cohort study of women of reproductive age (15-49 years) who died between March 21, 1999, and March 21, 2002, in four selected districts in four provinces: Kabul city, Kabul province (urban); Alisheng district, Laghman province (semirural); Maywand, Kandahar province (rural); and Ragh, Badakshan province (rural, most remote). Deaths among women of reproductive age were identified through a survey of all households in randomly selected villages and investigated through verbal-autopsy interviews of family members. FINDINGS: In a population of 90 816, 357 women of reproductive age died; 154 deaths were related to complications during pregnancy, childbirth, or the puerperal period. Most maternal deaths were caused by ante-partum haemorrhage, except in Ragh, where a greater proportion of women died of obstructed labour. All measures of maternal risk were high, especially in the more remote areas; the maternal mortality ratio (per 100,000 livebirths) was 418 (235-602) in Kabul, 774 (433-1115) in Alisheng, 2182 (1451-2913) in Maywand, and 6507 (5026-7988) in Ragh. In the two rural sites, no woman who died was assisted by a skilled birth attendant. INTERPRETATION: Maternal mortality in Afghanistan is high and becomes significantly greater with increasing remoteness. Deaths could be averted if complications were prevented through optimisation of general health status and if complications that occurred were treated to reduce their severity--efforts that require a multisectoral approach to increase availability and accessibility of health care.

Public nutrition in complex emergencies.

Public nutrition is a broad-based, problem-solving approach to addressing malnutrition in complex emergencies that combines analysis of nutritional risk and vulnerability with action-oriented strategies, including policies, programmes, and capacity development. This paper focuses on six broad areas: nutritional assessment, distribution of a general food ration, prevention and treatment of moderate malnutrition, treatment of severe malnutrition in children and adults, prevention and treatment of micronutrient deficiency diseases, and nutritional support for at-risk groups, including infants, pregnant and lactating women, elderly people, and people living with HIV. Learning and documenting good practice from previous emergencies, the promotion of good practice in current emergencies, and adherence to international standards and guidelines have contributed to establishing the field of public nutrition. However, many practical challenges reduce the effectiveness of nutritional interventions in complex emergencies, and important research and programmatic questions remain.

Lessons learned from complex emergencies over past decade.

Major advances have been made during the past decade in the way the international community responds to the health and nutrition consequences of complex emergencies. The public health and clinical response to diseases of acute epidemic potential has improved, especially in camps. Case-fatality rates for severely malnourished children have plummeted because of better protocols and products. Renewed focus is required on the major causes of death in conflict-affected societies--particularly acute respiratory infections, diarrhoea, malaria, measles, neonatal causes, and malnutrition--outside camps and often across regions and even political boundaries. In emergencies in sub-Saharan Africa, particularly southern Africa, HIV/AIDS is also an important cause of morbidity and mortality. Stronger coordination, increased accountability, and a more strategic positioning of non-governmental organisations and UN agencies are crucial to achieving lower maternal and child morbidity and mortality rates in complex emergencies and therefore for reaching the UN's Millennium Development Goals.
