Assessing longitudinal prenatal knowledge and skills retention among community birth attendants enrolled in a novel school.

Objective: Guatemala has one of the highest rates of maternal mortality in Central America. A total of 60% of births in Guatemala are attended by traditional Mayan birth attendants, or comadronas. Their prevalence in these communities makes them a valuable resource to bridge home births with safe prenatal care.

Usefulness of immature platelet fraction measurement in predicting hematologic recovery in patients with acute leukemias undergoing high-intensity chemotherapy and stem cell transplantation.

Background And Objectives: The immature platelet fraction (IPF) count is a parameter that quantifies young and reticulated platelets in peripheral blood, which reflects platelet production in the bone marrow. It has been used as a predictive model for bone marrow recovery in patients with acute leukemia after high-intensity chemotherapy and/or stem cell transplantation. This study aimed to evaluate IPF as a predictor of hematologic recovery in these patients.

Generalized, sublethal damage-based mathematical approach for improved modeling of clonogenic survival curve flattening upon hyperthermia, radiotherapy, and beyond.

. Mathematical modeling can offer valuable insights into the behavior of biological systems upon treatment. Different mathematical models (empirical, semi-empirical, and mechanistic) have been designed to predict the efficacy of either hyperthermia (HT), radiotherapy (RT), or their combination.

Source attribution, health risk analysis, and policy implications of PAHs and NPAHs in PM[Formula: see text] in Northern Mexico.

This research investigates the concentrations, sources, and health risks of polycyclic aromatic hydrocarbons (PAHs) and nitrated PAHs (NPAHs) in particulate matter with an aerodynamic diameter of 10 μm or less (PM[Formula: see text]) from critical urban centers in northern Mexico: Metropolitan Monterrey Area (MMA), Chihuahua (CHI), and Ciudad Juárez (CDJ). Advanced gas chromatography-mass spectrometry (GC-MS and GC-NCI-MS) revealed significant PAHs concentrations, with levels in MMA reaching 108.89 ± 99.

Fishery and ecology-related knowledge about plants among fishing communities along Laguna Lake, Philippines.

Background: Ethnobotanical knowledge about plant roles in fisheries is crucial for sustainable resource management. Local ecological knowledge helps understand dynamics of the lake ecosystem. Fishers use plants based on availability and characteristics while adapting to the changes in the environment.
