Assessing the Nature and Quality of Emergency Obstetric Care for Preventing Maternal and Perinatal Mortality in 8 Secondary and Tertiary Hospitals in Nigeria: Results of a Formative Research Study
<p>Nigeria suffers some of the highest rates of maternal and perinatal mortality in the world. Poor quality of obstetric care is a key factor, and although not quantified at a national level, local studies suggest that high rates of maternal and perinatal deaths are due to clinical management errors in hospitals. This project therefore explored the nature of existing practices and quality of clinical management of three leading causes of maternal and perinatal deaths (primary postpartum haemorrhage, eclampsia, and obstructed labour); implement an intervention package aimed at improving the quality of clinical management of these causes of deaths; and test the effectiveness of this package on quality of care indicators and maternal and perinatal outcomes. </p> <p>The study follows a quasi-experimental research design, using interrupted time series analysis for assessment over a three year period. Six public secondary care hospitals and two public tertiary care hospitals in both north and south of Nigeria were selected randomly. Formative research was conducted in all eight hospitals, and thereafter the intervention will be carried out in four hospitals, with the remaining four hospitals functioning as control sites. </p> <p>Clinical outcomes will be compared between intervention and control sites in a total of 2334 cases of PPH, preeclampsia/eclampsia and obstructed labour (based on an anticipated 50% reduction in case fatality rates, significance level of 0.05 and 80% power). This will consist of 1167 cases in the intervention sites and 1167 in the control sites. Maternal and perinatal mortality rates will serve as primary outcome measures. Secondary outcomes involve quality of care drawn from United Nations process indicators, skilled attendance index and data derived from this formative audit phase of the project.</p> <p>The results will enable the identification of a system-wide quality of care framework for improving the delivery of emergency obstetric care for the prevention of maternal and perinatal morbidity and mortality in Nigeria.</p>

The biology of prolonged lactation in wild Macaca sinica: Interbirth intervals, maternal depletion, infant mortality
<p>A sample of 442 female toque macaques distributed among 39 independent social groups were briefly captured, sedated, and released (within one day) during 13 different years in the period 1986-2002 at the natural forest site of Polonnaruwa, Sri Lanka, where long-term sociobiological research has been conducted (1968 to 2023). All macaques were individually identified and had known life-histories. Lactation was determined by testing females for the presence of absence of milk by manually massaging the mammary tissue. Female reproduction in this wild population was depicted from different perspectives. Firstly, lactation and weaning were linked to offspring age, as well as to female reproductive status (cycling, gestation, and quiescence). A second data set examines interbirth intervals in relation to lactation duration, diet, and somatic growth or parity. Differences in diet quality were also related to menarche. A third data set examined female body condition (using skinfold thickness as a measure of % body fat) to diet quality and differences in the expenditure of foraging time between lactating and non-lactating females. A fourth data set considered the relation between infant mortality during peak lactation and the depletion of female metabolic energy balance as indexed by early weaning (cessation of lactation) and a shift to female reproductive quiescence. In the publication some of these data were integrated with mother-infant behavioral relationships as cited from an independent study of the same population. A final data set indicates the names of participants who contributed to both the long-term demographic records, milk collections and estimates human effort for different phases of this research.</p>
Data from: Improving performance of hurdle models using rare-event weighted logistic regression: An application to maternal mortality data
<p>In this paper, the performance of hurdle models in rare events data is improved by modifying their binary component. The rare-event weighted logistic regression model is adopted in place of logistic regression to deal with class imbalance due to rare events. Poisson Hurdle Rare Event Weighted Logistic Regression (REWLR) and Negative Binomial Hurdle (NBH) REWLR are developed as two-part models which use the REWLR model to estimate the probability of a positive count and a Poisson or NB zero-truncated count model to estimate non-zero counts. The obtained results are numerically validated and then discussed from both the mathematical and the maternal mortality perspective. Numerical simulations are also presented to give a more complete representation of the model dynamics. Results obtained suggest that NB Hurdle REWLR is the best-performing model for zero-inflated count data due to rare events.</p>

Data from: On the importance of having a good mother: maternal investment affects duckling mortality risk in wood ducks
Most avian populations experience more variation in recruitment than adult survival, and twhich drives much of the change in population growth rates from year to year. In duck species, the probability of duckling survival is an important component of recruitment into the breeding population. We investigated how variation in maternal investment in offspring by nesting female wood duck Aix sponsa affected duckling mortality (1‐survival) to 60 days of age using capture‐mark‐recapture techniques. Our primary sample consisted of 3,035 ducklings, from 545 nests, that were marked with uniquely coded webtags on the day of hatch over nine nesting seasons (2008‐2016). We also included 4,437 HY and AHY individuals to increase precision on parameter estimates because some ducklings were not recaptured until after fledging. Duckling mortality was greatest during the first week of life (0.76, 85% C.I. 0.71, 0.81) and approached zero by the second week after hatching (0.005, 85% C.I. 0, 0.025). We observed a quadratic effect of hatch date on duckling mortality (βHD = 0.013, 85% CI 0.13, 0.20, βHD2 = 0.12, 85% CI 0.051, 0.017) of hatch date, suggesting that successful females improve fitness by nesting early in the year, but not too early (15 days before mean hatch). Increased egg volume and duckling mass reduced the probability of ducking mortality (βegg volume = ‐0.155, 85% CI ‐0.245, ‐0.075. βduckling mass = ‐7.56, 85% CI ‐10.67,‐4.45). Our results suggest that risk of mortality for ducklings is influenced, at least in part, by maternal effects, which are manifested through energy allocation and behavior during the breeding season. As such, individual heterogeneity among breeding females affects duckling mortality risk and likely the recruitment process for wood ducks.
