We present an experimental method to create a single high frequency optical trap for atoms based on an elongated Hermite-Gaussian TEM01 mode beam. This trap results in confinement strength similar to that which may be obtained in an optical lattice. We discuss an optical setup to produce the trapping beam and then detail a method to load a Bose-Einstein Condensate (BEC) into a TEM01 trap. Using this method, we have succeeded in producing individual highly confined lower dimensional condensates.

The potential impact of one-carbon metabolism (OCM)-related B vitamins (vitamin B, B, B, and folate) on colorectal cancer survival warrants investigation but research is sparse. This cohort study examined the association between the prediagnostic dietary intakes of OCM-related B vitamins and colorectal cancer survival. A total of 2799 colorectal cancer patients from the Guangdong Colorectal Cancer Cohort, enrolled at baseline in 2010, were followed for mortality outcomes through 2023.

Objectives: Patients who revisit the emergency department (ED) shortly after discharge are a high-risk group for complications and death, and these revisits may have been seriously affected by the COVID-19 pandemic. Detecting suspected COVID-19 cases in EDs is resource intensive. We examined the associations of screening workload for suspected COVID-19 cases with in-hospital mortality and intensive care unit (ICU) admission during short-term ED revisits.

To estimate maternal COVID-19, influenza, and pertussis vaccine uptake during pregnancy by insurance type and identify factors characterizing those vaccinated and unvaccinated. We conducted a US cohort study of pregnant individuals (for pregnancies ending December 11, 2020-September 30, 2022) using insurance claims data. We calculated vaccination probability using Kaplan-Meier methods and identified factors associated with vaccination through binomial regression with inverse probability weights.

Purpose: Patients with adolescent and young adult (AYA) cancer are recognized as a vulnerable subpopulation in high-income countries (HICs). Although survival gaps between HIC and low- and middle-income country (LMIC) children with cancer are well described, LMIC AYAs have been neglected. We conducted a systematic review to describe cancer outcomes among LMIC AYAs.

Background And Aim: Dysmenorrhea affects the majority of young women worldwide, but geographical and cultural differences can influence the reporting, impact and management of symptoms. Aotearoa New Zealand is a culturally diverse country, with a high proportion of Māori and Pacific peoples. The aim of this scoping review was to assess the current literature on the prevalence, impact and management strategies for dysmenorrhea in Aotearoa New Zealand.
