Evaluation of Labor Mirror Use During the Active Pushing Phase of the Second Stage of Labor.

Objective: To evaluate whether the use of a labor mirror during the active pushing phase of the second stage of labor is associated with a shorter duration of pushing. Additionally, we examined maternal and neonatal outcomes secondary to mirror use versus non-mirror use.

Design: Retrospective observational cohort study.

The Value of Medical Chart Reviews: A Methodological Approach to Supplement Mortality Data During Pandemic Outbreaks.

Administrative data may provide incomplete understanding of pandemic disease impact. Medical record review-based assessments of COVID-19-related causes of death were conducted among people with diagnosed HIV in New York State, which identified more COVID-19-related causes of death than Vital Statistics, thereby offering a deeper understanding of the pandemic's impact on this population.

A nuclear genome assembly of an extinct flightless bird, the little bush moa.

We present a draft genome of the little bush moa ()-one of approximately nine species of extinct flightless birds from Aotearoa, New Zealand-using ancient DNA recovered from a fossil bone from the South Island. We recover a complete mitochondrial genome at 249.9× depth of coverage and almost 900 megabases of a male moa nuclear genome at ~4 to 5× coverage, with sequence contiguity sufficient to identify more than 85% of avian universal single-copy orthologs.

Social Network Characteristics Associated with More Frequent HIV and STI Prevention Conversations: The N2 Cohort Study in Chicago.

Black cisgender sexually minoritized men (SMM) and transgender women (TW) are subgroups at highest risk of HIV and sexually transmitted infections (STIs) in the US. We sought to identify factors facilitating continued conversations - social reinforcement - surrounding HIV/STI prevention among this subgroup. Participants were recruited in Chicago from 2018 to 2019 from community health spaces.
