Predicting Mortality in Patients Hospitalized With Acute Myocardial Infarction: From the National Cardiovascular Data Registry.

Background: In-hospital mortality risk prediction is an important tool for benchmarking quality and patient prognostication. Given changes in patient characteristics and treatments over time, a contemporary risk model for patients with acute myocardial infarction (MI) is needed.

Methods: Data from 313 825 acute MI hospitalizations between January 2019 and December 2020 for adults aged ≥18 years at 784 sites in the National Cardiovascular Data Registry Chest Pain-MI Registry were used to develop a risk-standardized model to predict in-hospital mortality.

Provincial distribution of unintended pregnancy and its associated factors in Sierra Leone.

Background: Unintended pregnancy is a significant public health concern in Sierra Leone, with far-reaching consequences for both mothers and children. This issue impacts individual well-being, strains healthcare systems, and hinders socioeconomic development. This study examined the prevalence and factors associated with unintended pregnancy in Sierra Leone.

Socioeconomic and geographical inequalities in polio immunisation coverage among two-year-olds in Sierra Leone, 2008-2019.

Background: Polio, a debeilitating and potentially life-threatening disease, continues to pose a risk to young children globally. While vaccination offers a powerful shield, its reach is not always equal. This study explores socioeconomic and geographical inequalities in polio immunisation coverage among two-year-olds in Sierra Leone between 2008 and 2019.

Socioeconomic and geographical inequalities in adolescent fertility rates in Sierra Leone, 2008-2019.

Background: Sierra Leone, like many other sub-Saharan African countries, grapples with the challenge of high adolescent fertility rates. This study examines the socio-economic and geographical inequalities in adolescent fertility rates in Sierra Leone between 2008 and 2019.

Methods: Three rounds of the Sierra Leone Demographic and Health Surveys (2008, 2013, and 2019) were analysed to examine inequalities in adolescent fertility rates.

The effect of delta-9 tetrahydrocannabinol and methamphetamine on sustained attention in the jumping spider (Trite planiceps).
