Problem: The possible in vitro immunomodulating effect of beta-estradiol on phytohemagglutinin-stimulated human lymphocyte cultures was studied.

Method Of Study: Lymphocyte cultures from 12 healthy men and women aged 25-35 years were set up for 12 hr in the presence and in the absence of beta-estradiol, and the expression of the activation markers CD25, CD69, and CD71 was examined by flow cytometric analysis with specific fluorescent conjugated antibodies.

Results: Although the number of cases is small, in 10 of 12 cases in the presence of beta-estradiol in two different concentrations, a significantly decreased expression of CD69 could be observed. A slight decrease could also be observed for the Interleukin-2 receptor expression; however, the difference, in the presence or absence of beta-estradiol, was not significant.

Conclusions: The results suggest that in vitro addition of beta-estradiol can inhibit, to a certain degree, specific activation markers on phytohemagglutinin-stimulated lymphocytes from young men and women. The present study could not define the role of sex differences because of the small number of samples. A comparison between men and women at various ages in a greater number of cases, as well as studies on activation markers after treatments with estrogens, would be useful.

This study explores the relationship between 25-hydroxyvitamin D/calcium/alkaline phosphatase (ALP) levels and kidney stone development via cross-sectional and Mendelian randomization (MR) analyses. We used data from the National Health and Nutrition Examination Survey (NHANES) 2013 to 2018 to explore the associations of 25(OH)D metabolite, calcium, and ALP levels with kidney stone development, LDSC analysis to determine the associations between their genetically predicted levels and kidney stone development, and MR analysis to determine the causality of those relationship via genome-wide association studies (GWASs). The cross-sectional study revealed a relationship between ALP levels and kidney stone development (Model 1: OR = 1.

Objective: Conventional decompression surgery for beak-type ossification of the posterior longitudinal ligament (OPLL) of the thoracic spine, whether approached anteriorly or posteriorly, poses several challenges, including technical complexity, cerebrospinal fluid leakage, incomplete decompression, and potential neurological deterioration. Therefore, the authors introduce a novel technique, anterior sliding decompression osteotomy (ASDO), for thoracic myelopathy caused by OPLL and evaluate the efficacy and safety of this technique.

Methods: Six patients (4 men and 2 women) who underwent ASDO surgery for beak-type OPLL in the thoracic spine with a follow-up period of at least 2 years were included in the cohort.

Background: Cervical cancer screening program in Uganda is opportunistic and focuses mainly on women aged 25-49 years. Female sex workers (FSWs) are at increased risk of developing invasive cervical cancer. There is limited data regarding the uptake and acceptability of cervical cancer screening among FSWs in Uganda.

Background: In Uganda, adolescent girls', and young women's (AGYW-15-24 years) current HIV prevalence is fourfold compared with their male counterparts due to compounded social, economic, and environmental factors. Using the Protective Motivation Theory (PMT), we explored HIV-acquisition risk sources and perceived protective factors from AGYW and caregivers' perspective.

Materials And Methods: During 2018, we conducted a qualitative study guided by PMT to explore factors influencing HIV acquisition among AGYW.

Purpose: We sought to evaluate the relationship between blood vitamin A levels and myopia in adults aged ≥20 years in Korea.

Methods: We collected data of 15,899 participants aged ≥20 years from the Korean National Health and Nutrition Examination Survey. Participants underwent refraction tests to identify myopia and high myopia, and their blood pressure and obesity levels were measured.
