Atrial Fibrillation Impacts Inpatient Mortality, Length of Stay, Resource Utilization, Blood Transfusion, and Endotracheal Intubation in Cesarean Sections, Natural Spontaneous Deliveries, and Instrumental Deliveries: A Nationwide Analysis (2016-2020).

Background: Atrial fibrillation (AF) is rare during pregnancy and current data on the impact of AF during delivery is scarce. In this study, we aim to analyze the impact of AF in patients who underwent delivery via cesarean section (CS), natural spontaneous delivery (NSD), or instrumental delivery (ID).

Methods: This study analyzed discharge data from the National Inpatient Sample (NIS) from 2016 to 2020.

The Fabrication of Gold Nanostructures as SERS Substrates for the Detection of Contaminants in Water.

Gold nanostructures (AuNSs) were used to fabricate surface-enhanced Raman spectroscopy (SERS) substrates. These AuNSs were produced using the solid-state dewetting method from thin films. The fragmentation process was studied at 300 °C, with durations of thermal treatment of 1, 3, 6, and 12 h.

Prevalence of external auditory canal exostoses in surfers.

Objective: To determine (1) the prevalence of external auditory exostoses in a population of surfers and (2) the relationship between the length of time spent surfing and the prevalence, severity, and location of the exostoses.

Design: Cross-sectional epidemiological study.

Setting: General community.
