RESUMO
The Helping Babies Breathe Global Development Alliance (GDA) was a public-private partnership created simultaneously with the launch of the educational program Helping Babies Breathe to accelerate dissemination and implementation of neonatal resuscitation in low- and middle-income countries with the goal of reducing the global burden of neonatal mortality and morbidity related to birth asphyxia. Representatives from 6 organizations in the GDA highlight the recognized needs that motivated their participation and how they built on one another's strengths in resuscitation science and education, advocacy, frontline implementation, health system strengthening, and implementation research to achieve common goals. Contributions of time, talent, and financial resources from the community, government, and private corporations and foundations powered an initiative that transformed the landscape for neonatal resuscitation in low- and middle-income countries. The organizations describe the power of partnerships, the challenges they faced, and how each organization was shaped by the collaboration. Although great progress was achieved, lessons learned through the GDA and additional efforts must still be applied to the remaining challenges of prevention, widespread implementation, improvement in the quality of care, and sustainable integration of neonatal resuscitation and essential newborn care into the fabric of health care systems.

Background: Previous studies suggest that cases of Ebola virus disease (EVD) may go unreported because they are asymptomatic or unrecognized, but evidence is limited by study designs and sample size. Methods: A large population-based survey was conducted (n = 3415) to assess animal exposures and behaviors associated with Ebolavirus antibody prevalence in rural Kasai Oriental province of the Democratic Republic of Congo (DRC). Fourteen villages were randomly selected and all healthy individuals ≥1 year of age were eligible. Results: Overall, 11% of subjects tested positive for Zaire Ebolavirus (EBOV) immunoglobulin G antibodies. Odds of seropositivity were higher for study participants older than 15 years of age and for males. Those residing in Kole (closer to the outbreak site) tested positive at a rate 1.6× higher than Lomela, with seropositivity peaking at a site located between Kole and Lomela. Multivariate analyses of behaviors and animal exposures showed that visits to the forest or hunting and exposure to rodents or duikers predicted a higher likelihood of EBOV seropositivity. Conclusions: These results provide serologic evidence of Ebolavirus exposure in a population residing in non-EBOV outbreak locations in the DRC and define statistically significant activities and animal exposures that associate with EBOV seropositivity.

Due to the high level of biological diversity in the Congo Basin and human population dependence on bushmeat, the DRC represents an ideal location for expanding knowledge on wild animal exposures and thus the potential for transmission of zoonotic pathogens. However, limited information exists on patterns and extent of contact with wildlife in such communities. Using a cross-sectional study, 14 villages in the Sankuru Province of the DRC were surveyed between August and September 2007. Villagers ≥ 1 year of age and at home of the time of the survey were eligible and enrolled to describe and assess factors associated with animal exposures (both activity and type of animal). Among respondents, 91% reported exposure to rodents, 89% to duikers, 78% to non-human primates (NHPs), and 32% reported contact with bats in the month prior to the survey. The most frequently reported activities included eating (95%), cooking (70%), and butchering or skinning of animals (55%). The activities and animals to which subjects had contact varied by sex and age. Moreover, we observed a high correlation of the same activities across animal types. In this and other populations that rely on bushmeat, there is a high frequency of exposure to multiple animal species through various modalities. In the event of future zoonotic disease outbreaks, effective public health interventions and campaigns that mitigate the risk of animal contact during outbreaks need to be broad to include various modes of contact and should be directed to both men and women across all age groups. As available information is limited, further studies are necessary to better understand the complex relationships and exposures individuals have with animals.

BACKGROUND: We investigated associations between maternal characteristics, access to care, and obstetrical complications including near miss status on admission or during hospitalization on perinatal outcomes among Indonesian singletons. METHODS: We prospectively collected data on inborn singletons at two hospitals in East Java. Data included socio-demographics, reproductive, obstetric and neonatal variables. Reduced multivariable models were constructed. Outcomes of interest included low and very low birthweight (LBW/VLBW), asphyxia and death. RESULTS: Referral from a care facility was associated with a reduced risk of LBW and VLBW [AOR = 0.28, 95% CI = 0.11-0.69, AOR = 0.18, 95% CI = 0.04-0.75, respectively], stillbirth [AOR = 0.41, 95% CI = 0.18-0.95], and neonatal death [AOR = 0.2, 95% CI = 0.05-0.81]. Mothers age <20 years increased the risk of VLBW [AOR = 6.39, 95% CI = 1.82-22.35] and neonatal death [AOR = 4.10, 95% CI = 1.29-13.02]. Malpresentation on admission increased the risk of asphyxia [AOR = 4.65, 95% CI = 2.23-9.70], stillbirth [AOR = 3.96, 95% CI = 1.41-11.15], and perinatal death [AOR = 3.89 95% CI = 1.42-10.64], as did poor prenatal care (PNC) [AOR = 11.67, 95%CI = 2.71-16.62]. Near-miss on admission increased the risk of neonatal [AOR = 11.67, 95% CI = 2.08-65.65] and perinatal death [AOR = 13.08 95% CI = 3.77-45.37]. CONCLUSIONS: Mothers in labor should be encouraged to seek care early and taught to identify early danger signs. Adequate PNC significantly reduced perinatal deaths. Improved hospital management of malpresentation may significantly reduce perinatal morbidity and mortality. The importance of hospital-based prospective studies helps evaluate specific areas of need in training of obstetrical care providers.

BACKGROUND: Infants of women with lower education levels are at higher risk for perinatal mortality. OBJECTIVES: We explored the impact of training birth attendants and pregnant women in the Essential Newborn Care (ENC) Program on fresh stillbirths (FSBs) and early (7-day) neonatal deaths (END) by maternal education level in developing countries. METHODS: A train-the-trainer model was used with local instructors in rural communities in six countries (Argentina, Democratic Republic of the Congo, Guatemala, India, Pakistan, and Zambia). Data were collected using a pre-/post-active baseline controlled study design. RESULTS: A total of 57,643 infants/mothers were enrolled. The follow-up rate at 7 days of age was 99.2%. The risk for FSB and END was higher for mothers with 0-7 years of education than for those with ≥8 years of education during both the pre- and post-ENC periods in unadjusted models and in models adjusted for confounding. The effect of ENC differed as a function of maternal education for FSB (interaction p = 0.041) without evidence that the effect of ENC differed as a function of maternal education for END. The model-based estimate of FSB risk was reduced among mothers with 0-7 years of education (19.7/1,000 live births pre-ENC, CI: 16.3, 23.0 vs. 12.2/1,000 live births post-ENC, CI: 16.3, 23.0, p < 0.001), but was not significantly different for mothers with ≥8 years of education, respectively. CONCLUSION: A low level of maternal education was associated with higher risk for FSB and END. ENC training was more effective in reducing FSB among mothers with low education levels.

BACKGROUND: The first minutes after birth are critical to reducing neonatal mortality. Helping Babies Breathe (HBB) is a simulation-based neonatal resuscitation program for low resource settings. We studied the impact of initial HBB training followed by refresher training on the knowledge and skills of the birth attendants in facilities. METHODS: We conducted HBB trainings in 71 facilities in the NICHD Global Network research sites (Nagpur and Belgaum, India and Eldoret, Kenya), with a 6:1 ratio of facility trainees to Master Trainers (MT). Because of staff turnover, some birth attendants (BA) were trained as they joined the delivery room staff, after the initial training was completed (catch-up initial training). We compared pass rates for skills and knowledge pre- and post- initial HBB training and following refresher training among active BAs. An Objective Structured Clinical Examination (OSCE) B tested resuscitation skill retention by comparing post-initial training performance with pre-refresher training performance. We identified factors associated with loss of skills in pre-refresher training performance using multivariable logistic regression analysis. Daily bag and mask ventilation practice, equipment checks and supportive supervision were stressed as part of training. RESULTS: One hundred five MT (1.6 MT per facility) conducted initial and refresher HBB trainings for 835 BAs; 76% had no prior resuscitation training. Initial training improved knowledge and skills: the pass percentage for knowledge tests improved from 74 to 99% (p < 0.001). Only 5% could ventilate a newborn mannequin correctly before initial training but 97% passed the post-initial ventilation training test (p < 0.0001) and 99% passed the OSCE B resuscitation evaluation. During pre-refresher training evaluation, a mean of 6.7 (SD 2.49) months after the initial training, 99% passed the knowledge test, but the successful completion rate fell to 81% for the OSCE B resuscitation skills test. Characteristics associated with deterioration of resuscitation skills were BAs from tertiary care facilities, no prior resuscitation training, and the timing of training (initial vs. catch-up training). CONCLUSIONS: HBB training significantly improved neonatal resuscitation knowledge and skills. However, skills declined more than knowledge over time. Ongoing skills practice and monitoring, more frequent retesting, and refresher trainings are needed to maintain neonatal resuscitation skills.

BACKGROUND: Whether facility-based implementation of Helping Babies Breathe (HBB) reduces neonatal mortality at a population level in low and middle income countries (LMIC) has not been studied. Therefore, we evaluated HBB implementation in this context where our study team has ongoing prospective outcome data on all pregnancies regardless of place of delivery. METHODS: We compared outcomes of birth cohorts in three sites in India and Kenya pre-post implementation of a facility-based intervention, using a prospective, population-based registry in 52 geographic clusters. Our hypothesis was that HBB implementation would result in a 20 % decrease in the perinatal mortality rate (PMR) among births ≥1500 g. RESULTS: We enrolled 70,704 births during two 12-month study periods. Births within each site did not differ pre-post intervention, except for an increased proportion of <2500 g newborns and deliveries by caesarean section in the post period. There were no significant differences in PMR among all registry births; however, a post-hoc analysis stratified by birthweight documented improvement in <2500 g mortality in Belgaum in both registry and in HBB-trained facility births. No improvement in <2500 g mortality measures was noted in Nagpur or Kenya and there was no improvement in normal birth weight survival. CONCLUSIONS: Rapid scale up of HBB training of facility birth attendants in three diverse sites in India and Kenya was not associated with consistent improvements in mortality among all neonates ≥1500 g; however, differential improvements in <2500 g survival in Belgaum suggest the need for careful implementation of HBB training with attention to the target population, data collection, and ongoing quality monitoring activities. TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov: NCT01681017 .

BACKGROUND: The Golden Minute®, the first minute following birth of a newborn, is a critical period for establishing ventilation after delivery, as emphasized in the Helping Babies Breathe® and other resuscitation training programs. Previous studies have reinforced training through observers' evaluation of this time period; although observation is useful for research, it may not be a sustainable method to support resuscitation practice in low-resource settings where few birth attendants are available. In order to reinforce resuscitation within The Golden Minute®, we sought to develop a simple mobile delivery-room timer on an Android cell phone platform for birth attendants to use at the time of delivery. METHODS: We developed and evaluated a mobile delivery room timer to document the time interval from birth to the initiation of newborn crying/spontaneous respiration or bag and mask ventilation in a convenience sample of women who delivered in five hospitals in Karnataka, India. The mobile delivery room timer is an Android cell phone-based application that recorded key events including crowning, delivery, and crying/spontaneous respiration or bag and mask ventilation. The mobile delivery room timer recorded the birth attendant verbally indicating the time of crowning, birth-(defined as when the entire baby was delivered), crying/spontaneous respiration or bag and mask ventilation. The mobile delivery room timer results were validated in a subsample by a trained observer (nurse) who independently recorded the time between delivery and initiation of crying/spontaneous respiration or bag and mask ventilation. RESULTS: Of the total 4,597 deliveries, 2,107 (46%) were timed; a sample (n = 438) of these deliveries was also observed by a trained nurse. There was high concordance between the mobile delivery room timer and observed time elapsed between birth and crying/spontaneous respiration or ventilation (correlation =0.94, p < 0.0001). The majority of neonates in both groups cried/breathed spontaneously or received bag and mask ventilation by 1 min (430/438 by the timer vs. 433/438 for observer). CONCLUSIONS: We demonstrated that a simple mobile delivery room timer application was feasible to use during delivery and provided valid observations of the time to crying/spontaneous respiration or bag and mask ventilation. This type of tool may be useful in reinforcing neonatal resuscitation training and the need to ensure spontaneous or assisted ventilation by The Golden Minute®.

OBJECTIVES: This study assessed whether community mobilization and interventions to improve emergency obstetric and newborn care reduced perinatal mortality (PMR) and neonatal mortality rates (NMR) in Belgaum, India. METHODS: The cluster-randomised controlled trial was conducted in Belgaum District, Karnataka State, India. Twenty geographic clusters were randomized to control or the intervention. The intervention engaged and mobilized community and health authorities to leverage support; strengthened community-based stabilization, referral, and transportation; and aimed to improve quality of care at facilities. RESULTS: 17,754 Intervention births and 15,954 control births weighing ≥1000 g, respectively, were enrolled and analysed. Comparing the baseline period to the last 6 months period, the NMR was lower in the intervention versus control clusters (OR 0.60, 95% CI 0.34-1.06, p = 0.076) as was the PMR (OR 0.74, 95% CI 0.46-1.19, p = 0.20) although neither reached statistical significance. Rates of facility birth and caesarean section increased among both groups. There was limited influence on quality of care measures. CONCLUSIONS FOR PRACTICE: The intervention had large but not statistically significant effects on neonatal and perinatal mortality. Community mobilization and increased facility care may ultimately improve neonatal and perinatal survival, and are important in the context of the global transition towards institutional delivery.

BACKGROUND: Consequences of exposure to household air pollution (HAP) from biomass fuels used for cooking on neonatal deaths and stillbirths is poorly understood. In a large multi-country observational study, we examined whether exposure to HAP was associated with perinatal mortality (stillbirths from gestation week 20 and deaths through day 7 of life) as well as when the deaths occurred (macerated, non-macerated stillbirths, very early neonatal mortality (day 0-2) and later neonatal mortality (day 3-28). Questions addressing household fuel use were asked at pregnancy, delivery, and neonatal follow-up visits in a prospective cohort study of pregnant women in rural communities in five low and lower middle income countries participating in the Global Network for Women and Children's Health's Maternal and Newborn Health Registry. The study was conducted between May 2011 and October 2012. Polluting fuels included kerosene, charcoal, coal, wood, straw, crop waste and dung. Clean fuels included electricity, liquefied petroleum gas (LPG), natural gas and biogas. RESULTS: We studied the outcomes of 65,912 singleton pregnancies, 18 % from households using clean fuels (59 % LPG) and 82 % from households using polluting fuels (86 % wood). Compared to households cooking with clean fuels, there was an increased risk of perinatal mortality among households using polluting fuels (adjusted relative risk (aRR) 1.44, 95 % confidence interval (CI) 1.30-1.61). Exposure to HAP increased the risk of having a macerated stillbirth (adjusted odds ratio (aOR) 1.66, 95%CI 1.23-2.25), non-macerated stillbirth (aOR 1.43, 95 % CI 1.15-1.85) and very early neonatal mortality (aOR 1.82, 95 % CI 1.47-2.22). CONCLUSIONS: Perinatal mortality was associated with exposure to HAP from week 20 of pregnancy through at least day 2 of life. Since pregnancy losses before labor and delivery are difficult to track, the effect of exposure to polluting fuels on global perinatal mortality may have previously been underestimated. TRIAL REGISTRATION: ClinicalTrials.gov NCT01073475.
RESUMO
BACKGROUND: The positive effects of early developmental intervention (EDI) on early child development have been reported in numerous controlled trials in a variety of countries. An important aspect to determining the efficacy of EDI is the degree to which dosage is linked to outcomes. However, few studies of EDI have conducted such analyses. This observational cohort study examined the association between treatment dose and children's development when EDI was implemented in three low and low-middle income countries as well as demographic and child health factors associated with treatment dose. METHODS: Infants (78 males, 67 females) born in rural communities in India, Pakistan, and Zambia received a parent-implemented EDI delivered through biweekly home visits by trainers during the first 36 months of life. Outcome was measured at age 36 months with the Mental (MDI) and Psychomotor (PDI) Development Indices of the Bayley Scales of Infant Development-II. Treatment dose was measured by number of home visits completed and parent-reported implementation of assigned developmental stimulation activities between visits. Sociodemographic, prenatal, perinatal, and child health variables were measures as correlates. RESULTS: Average home visits dose exceeded 91% and mothers engaged the children in activities on average 62.5% of days. Higher home visits dose was significantly associated with higher MDI (mean for dose quintiles 1-2 combined = 97.8, quintiles 3-5 combined = 103.4, p = 0.0017). Higher treatment dose was also generally associated with greater mean PDI, but the relationships were non-linear. Location, sociodemographic, and child health variables were associated with treatment dose. CONCLUSIONS: Receiving a higher dose of EDI during the first 36 months of life is generally associated with better developmental outcomes. The higher benefit appears when receiving ≥91% of biweekly home visits and program activities on ≥67% of days over 3 years. It is important to ensure that EDI is implemented with a sufficiently high dose to achieve desired effect. To this end groups at risk for receiving lower dose can be identified and may require special attention to ensure adequate effect.

OBJECTIVE: To quantify maternal, fetal and neonatal mortality in low- and middle-income countries, to identify when deaths occur and to identify relationships between maternal deaths and stillbirths and neonatal deaths. METHODS: A prospective study of pregnancy outcomes was performed in 106 communities at seven sites in Argentina, Guatemala, India, Kenya, Pakistan and Zambia. Pregnant women were enrolled and followed until six weeks postpartum. FINDINGS: Between 2010 and 2012, 214,070 of 220,235 enrolled women (97.2%) completed follow-up. The maternal mortality ratio was 168 per 100,000 live births, ranging from 69 per 100,000 in Argentina to 316 per 100,000 in Pakistan. Overall, 29% (98/336) of maternal deaths occurred around the time of delivery: most were attributed to haemorrhage (86/336), pre-eclampsia or eclampsia (55/336) or sepsis (39/336). Around 70% (4349/6213) of stillbirths were probably intrapartum; 34% (1804/5230) of neonates died on the day of delivery and 14% (755/5230) died the day after. Stillbirths were more common in women who died than in those alive six weeks postpartum (risk ratio, RR: 9.48; 95% confidence interval, CI: 7.97-11.27), as were perinatal deaths (RR: 4.30; 95% CI: 3.26-5.67) and 7-day (RR: 3.94; 95% CI: 2.74-5.65) and 28-day neonatal deaths (RR: 7.36; 95% CI: 5.54-9.77). CONCLUSION: Most maternal, fetal and neonatal deaths occurred at or around delivery and were attributed to preventable causes. Maternal death increased the risk of perinatal and neonatal death. Improving obstetric and neonatal care around the time of birth offers the greatest chance of reducing mortality.

BACKGROUND: Neonatal deaths account for over 40% of all under-5 year deaths; their reduction is increasingly critical for achieving Millennium Development Goal 4. An estimated 3 million newborns die annually during their first month of life; half of these deaths occur during delivery or within 24 hours. Every year, 6 million babies require help to breathe immediately after birth. Resuscitation training to help babies breathe and prevent/manage birth asphyxia is not routine in low-middle income facility settings. Helping Babies Breathe (HBB), a simulation-training program for babies wherever they are born, was developed for use in low-middle income countries. We evaluated whether HBB training of facility birth attendants reduces perinatal mortality in the Eunice Kennedy Shriver National Institute of Child Health and Human Development's Global Network research sites. METHODS/DESIGN: We hypothesize that a two-year prospective pre-post study to evaluate the impact of a facility-based training package, including HBB and essential newborn care, will reduce all perinatal mortality (fresh stillbirth or neonatal death prior to 7 days) among the Global Network's Maternal Neonatal Health Registry births ≥1500 grams in the study clusters served by the facilities. We will also evaluate the effectiveness of the HBB training program changing on facility-based perinatal mortality and resuscitation practices. Seventy-one health facilities serving 52 geographically-defined study clusters in Belgaum and Nagpur, India, and Eldoret, Kenya, and 30,000 women will be included. Primary outcome data will be collected by staff not involved in the HBB intervention. Additional data on resuscitations, resuscitation debriefings, death audits, quality monitoring and improvement will be collected. HBB training will include training of MTs, facility level birth attendants, and quality monitoring and improvement activities. DISCUSSION: Our study will evaluate the effect of a HBB/ENC training and quality monitoring and improvement package on perinatal mortality using a large multicenter design and approach in 71 resource-limited health facilities, leveraging an existing birth registry to provide neonatal outcomes through day 7. The study will provide the evidence base, lessons learned, and best practices that will be essential to guiding future policy and investment in neonatal resuscitation.

Monkeypox virus is a zoonotic virus endemic to Central Africa. Although active disease surveillance has assessed monkeypox disease prevalence and geographic range, information about virus diversity is lacking. We therefore assessed genome diversity of viruses in 60 samples obtained from humans with primary and secondary cases of infection from 2005 through 2007. We detected 4 distinct lineages and a deletion that resulted in gene loss in 10 (16.7%) samples and that seemed to correlate with human-to-human transmission (p = 0.0544). The data suggest a high frequency of spillover events from the pool of viruses in nonhuman animals, active selection through genomic destabilization and gene loss, and increased disease transmissibility and severity. The potential for accelerated adaptation to humans should be monitored through improved surveillance.

We conducted a theory-driven process evaluation of a cluster randomized controlled trial comparing two types of complementary feeding (meat versus fortified cereal) on infant growth in Guatemala, Pakistan, Zambia and the Democratic Republic of Congo. We examined process evaluation indicators for the entire study cohort (N = 1236) using chi-square tests to examine differences between treatment groups. We administered exit interviews to 219 caregivers and 45 intervention staff to explore why caregivers may or may not have performed suggested infant feeding behaviors. Multivariate regression analysis was used to determine the relationship between caregiver scores and infant linear growth velocity. As message recall increased, irrespective of treatment group, linear growth velocity increased when controlling for other factors (P < 0.05), emphasizing the importance of study messages. Our detailed process evaluation revealed few differences between treatment groups, giving us confidence that the main trial's lack of effect to reverse the progression of stunting cannot be explained by differences between groups or inconsistencies in protocol implementation. These findings add to an emerging body of literature suggesting limited impact on stunting of interventions initiated during the period of complementary feeding in impoverished environments. The early onset and steady progression support the provision of earlier and comprehensive interventions.

AIM: To determine the rates of multiple gestation, stillbirth, and perinatal and neonatal mortality and to determine health care system characteristics related to perinatal mortality of these pregnancies in low- and middle-income countries. METHODS: Pregnant women residing within defined geographic boundaries located in six countries were enrolled and followed to 42 days postpartum. RESULTS: Multiple gestations were 0.9% of births. Multiple gestations were more likely to deliver in a health care facility compared with singletons (70 and 66%, respectively, p < 0.001), to be attended by skilled health personnel (71 and 67%, p < 0.001), and to be delivered by cesarean (18 versus 9%, p < 0.001). Multiple-gestation fetuses had a relative risk (RR) for stillbirth of 2.65 (95% confidence interval [CI] 2.06, 3.41) and for perinatal mortality rate (PMR) a RR of 3.98 (95% CI 3.40, 4.65) relative to singletons (both p < 0.0001). Neither delivery in a health facility nor the cesarean delivery rate was associated with decreased PMR. Among multiple-gestation deliveries, physician-attended delivery relative to delivery by other health providers was associated with a decreased risk of perinatal mortality. CONCLUSIONS: Multiple gestations contribute disproportionately to PMR in low-resource countries. Neither delivery in a health facility nor the cesarean delivery rate is associated with improved PMR.

OBJECTIVE: To evaluate the incidence of death or neurodevelopmental impairment (NDI) at 18-22 months corrected age in subjects enrolled in a trial of early dexamethasone treatment to prevent death or chronic lung disease in extremely low birth weight infants. STUDY DESIGN: Evaluation of infants at 18-22 months corrected age included anthropomorphic measurements, a standard neurological examination, and the Bayley Scales of Infant Development-II, including the Mental Developmental Index and the Psychomotor Developmental Index. NDI was defined as moderate or severe cerebral palsy, Mental Developmental Index or Psychomotor Developmental Index <70, blindness, or hearing impairment. RESULTS: Death or NDI at 18-22 months corrected age was similar in the dexamethasone and placebo groups (65% vs 66%, P = .99 among those with known outcome). The proportion of survivors with NDI was also similar, as were mean values for weight, length, and head circumference and the proportion of infants with poor growth (50% vs 41%, P = .42 for weight less than 10th percentile); 49% of infants in the placebo group received treatment with corticosteroid compared with 32% in the dexamethasone group (P = .02). CONCLUSION: The risk of death or NDI and rate of poor growth were high but similar in the dexamethasone and placebo groups. The lack of a discernible effect of early dexamethasone on neurodevelopmental outcome may be due to frequent clinical corticosteroid use in the placebo group.

BACKGROUND: Stunting is prevalent by the age of 6 months in the indigenous population of the Western Highlands of Guatemala. AIM: The objective of this study was to determine the time course and predictors of linear growth failure and weight-for-age in early infancy. STUDY DESIGN AND SUBJECTS: One hundred and forty eight term newborns had measurements of length and weight in their homes, repeated at 3 and 6 months. Maternal measurements were also obtained. RESULTS: Mean ± SD length-for-age Z-score (LAZ) declined from newborn -1.0 ± 1.01 to -2.20 ± 1.05 and -2.26 ± 1.01 at 3 and 6 months respectively. Stunting rates for newborn, 3 and 6 months were 47%, 53% and 56% respectively. A multiple regression model (R(2) = 0.64) demonstrated that the major predictor of LAZ at 3 months was newborn LAZ with the other predictors being newborn weight-for-age Z-score (WAZ), gender and maternal education∗maternal age interaction. Because WAZ remained essentially constant and LAZ declined during the same period, weight-for-length Z-score (WLZ) increased from -0.44 to +1.28 from birth to 3 months. The more severe the linear growth failure, the greater WAZ was in proportion to the LAZ. CONCLUSION: The primary conclusion is that impaired fetal linear growth is the major predictor of early infant linear growth failure indicating that prevention needs to start with maternal interventions.

BACKGROUND: Fetal and neonatal mortality rates in low-income countries are at least 10-fold greater than in high-income countries. These differences have been related to poor access to and poor quality of obstetric and neonatal care. METHODS: This trial tested the hypothesis that teams of health care providers, administrators and local residents can address the problem of limited access to quality obstetric and neonatal care and lead to a reduction in perinatal mortality in intervention compared to control locations. In seven geographic areas in five low-income and one middle-income country, most with high perinatal mortality rates and substantial numbers of home deliveries, we performed a cluster randomized non-masked trial of a package of interventions that included community mobilization focusing on birth planning and hospital transport, community birth attendant training in problem recognition, and facility staff training in the management of obstetric and neonatal emergencies. The primary outcome was perinatal mortality at ≥28 weeks gestation or birth weight ≥1000 g. RESULTS: Despite extensive effort in all sites in each of the three intervention areas, no differences emerged in the primary or any secondary outcome between the intervention and control clusters. In both groups, the mean perinatal mortality was 40.1/1,000 births (P = 0.9996). Neither were there differences between the two groups in outcomes in the last six months of the project, in the year following intervention cessation, nor in the clusters that best implemented the intervention. CONCLUSIONS: This cluster randomized comprehensive, large-scale, multi-sector intervention did not result in detectable impact on the proposed outcomes. While this does not negate the importance of these interventions, we expect that achieving improvement in pregnancy outcomes in these settings will require substantially more obstetric and neonatal care infrastructure than was available at the sites during this trial, and without them provider training and community mobilization will not be sufficient. Our results highlight the critical importance of evaluating outcomes in randomized trials, as interventions that should be effective may not be. TRIAL REGISTRATION: ClinicalTrials.gov NCT01073488.

Climate change is predicted to result in changes in the geographic ranges and local prevalence of infectious diseases, either through direct effects on the pathogen, or indirectly through range shifts in vector and reservoir species. To better understand the occurrence of monkeypox virus (MPXV), an emerging Orthopoxvirus in humans, under contemporary and future climate conditions, we used ecological niche modeling techniques in conjunction with climate and remote-sensing variables. We first created spatially explicit probability distributions of its candidate reservoir species in Africa's Congo Basin. Reservoir species distributions were subsequently used to model current and projected future distributions of human monkeypox (MPX). Results indicate that forest clearing and climate are significant driving factors of the transmission of MPX from wildlife to humans under current climate conditions. Models under contemporary climate conditions performed well, as indicated by high values for the area under the receiver operator curve (AUC), and tests on spatially randomly and non-randomly omitted test data. Future projections were made on IPCC 4(th) Assessment climate change scenarios for 2050 and 2080, ranging from more conservative to more aggressive, and representing the potential variation within which range shifts can be expected to occur. Future projections showed range shifts into regions where MPX has not been recorded previously. Increased suitability for MPX was predicted in eastern Democratic Republic of Congo. Models developed here are useful for identifying areas where environmental conditions may become more suitable for human MPX; targeting candidate reservoir species for future screening efforts; and prioritizing regions for future MPX surveillance efforts.
