PodGPT: An audio-augmented large language model for research and education.

The proliferation of scientific podcasts has generated an extensive repository of audio content, rich in specialized terminology, diverse topics, and expert dialogues. Here, we introduce a computational framework designed to enhance large language models (LLMs) by leveraging this informational content from publicly accessible podcast data across science, technology, engineering, mathematics and medical (STEMM) disciplines. This dataset, comprising over 3, 700 hours of audio content, was transcribed to generate over 42 million text tokens.

Group B Streptococcus Infection and Obstetric Hemorrhage Risk.

Objective: To elucidate the association between GBS infection and maternal risk for obstetric hemorrhage (OBH) and OBH-related morbidities (OBH-M).

Methods: This was a retrospective cohort study of all deliveries with a documented GBS status at a single large academic medical center from 2018 to 2019. GBS status was determined by either urine culture or rectovaginal culture collected during the antepartum period.

Association between duration of intrapartum oxytocin exposure and obstetric hemorrhage.

Purpose: Prolonged duration of intrapartum oxytocin exposure is included as a risk factor within widely adopted obstetric hemorrhage risk stratification tools. However, the duration of exposure that confers increased risk is poorly understood. This study aimed to assess the association between duration of intrapartum oxytocin exposure and obstetric blood loss, as measured by quantitative blood loss, and hemorrhage-related maternal morbidity.

Intrapartum Risk Factors and Prediction of Obstetric Hemorrhage-Related Morbidity.

Objective: The aim of this study was to assess whether inclusion of intrapartum risk factors improves our obstetric hemorrhage risk stratification tool in predicting obstetric hemorrhage, transfusion, and related severe morbidity.

Study Design: This is a retrospective cohort study using all live deliveries at a single institution over a 2-year period ( = 5,332). Obstetric hemorrhage risk factors, hemorrhage burden, and severe maternal morbidity index outcomes were assessed through chart abstraction.

Integration of Clinical Skills into Preclinical Medical Curriculum Via a Low-Cost Femoral Triangle Ultrasound Model.

We created a low-cost femoral triangle model that allows first year medical students to practice ultrasound-guided procedures while reinforcing their knowledge of femoral triangle anatomy. Use of this model also increased opportunities for informal near-peer teaching and student involvement in the creation of instructional materials.

Intrapartum magnesium sulfate exposure and obstetric hemorrhage risk.

Background: The gold standard intrapartum treatment for preeclampsia with severe features is magnesium sulfate in order to provide prophylaxis against eclampsia. However, though magnesium sulfate is known to have a relaxant effect on uterine muscle, there have been variable reports in the literature in regard to the association between magnesium and obstetric hemorrhage (OBH).

Objective: We aim to compare OBH incidence in patients with hypertensive disease of pregnancy (HDP) with or without exposure to intrapartum magnesium sulfate.

The wiring diagram of a glomerular olfactory system.

The sense of smell enables animals to react to long-distance cues according to learned and innate valences. Here, we have mapped with electron microscopy the complete wiring diagram of the Drosophila larval antennal lobe, an olfactory neuropil similar to the vertebrate olfactory bulb. We found a canonical circuit with uniglomerular projection neurons (uPNs) relaying gain-controlled ORN activity to the mushroom body and the lateral horn.

Reverse-correlation analysis of navigation dynamics in Drosophila larva using optogenetics.

Neural circuits for behavior transform sensory inputs into motor outputs in patterns with strategic value. Determining how neurons along a sensorimotor circuit contribute to this transformation is central to understanding behavior. To do this, a quantitative framework to describe behavioral dynamics is needed.
