Purpose: Steroid hormone metabolism plays an essential role in high-altitude pulmonary edema (HAPE) progression. This study aimed to investigate the association between polymorphism in seven steroid hormone metabolism genes (, and ) and HAPE susceptibility among Han Chinese.
Patients And Methods: A total of 41 tagSNPs in the seven genes were genotyped using Sequenom MassARRAY SNP assays from 169 HAPE patients (HAPE-p) and 309 matched Han Chinese individuals resistant to HAPE (HAPE-r). The genotypic and allele frequencies, odds ratios (ORs), and 95% confidence intervals (95% CIs) were calculated.
Results: Four SNPs, including the allele C of rs6203 (p = 0.034, OR [95% CI] = 1.344 [1.022-1.767]) in , allele G of rs3740397 (p = 0.044, OR [95% CI] = 1.314 [1.007-1.714]) and allele C of rs10786712 (p = 0.039, OR [95% CI] = 0.751 [0.572-0.986]) in , and allele T of rs6402 (p = 0.006, OR [95% CI] = 0.504 [0.306-0.830]) in , were significantly associated with HAPE. The distribution of the genotypes of these SNPs also significantly differed between the HAPE-p and HAPE-r groups. Moreover, six haplotypes (the linkage disequilibrium block including rs10883783, rs4919686, rs3740397, rs3824755, and rs10786712) of were also significantly associated with HAPE.
Conclusion: The four SNPs located in (rs6203), (rs3740397 and rs10786712), and (rs6402) and the six haplotypes of are likely to have an effect on HAPE.

Objective: Early and accurate diagnosis of prostate cancer (PC) is crucial for effective treatment. Diagnosing clinically insignificant cancers can lead to overdiagnosis and overtreatment, highlighting the importance of accurately selecting patients for further evaluation based on improved risk prediction tools. Novel biomarkers offer promise for enhancing this diagnostic process.

Study Design: Meta-Analysis.
Objective: The purpose of this systematic review and meta-analysis was to pool the available data comparing MIS to open surgery for thoracolumbar fractures and provide a more comprehensive assessment on this topic.
Background: There remains a debate over whether minimally invasive surgery (MIS) or open fixation provides superior outcomes for patients with thoracolumbar fractures.
Impact of Frailty on Antihypertensive Treatment in Older Adults.

Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.
Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.

Background: Suboptimal cardiovascular health (CVH) in pregnancy is associated with adverse maternal and offspring outcomes. To guide public health efforts to reduce disparities in maternal CVH, we determined the contribution of individual- and neighborhood-level factors to racial and ethnic differences in early pregnancy CVH.
Methods: We included nulliparous individuals with singleton pregnancies who self-identified as Hispanic, non-Hispanic Black (NHB), or non-Hispanic White (NHW) and participated in the nuMoM2b cohort study (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be).
Validation Status of Electronic Sphygmomanometers in China: A National Survey.

Clinical Research Institute, Institute of Advanced Clinical Medicine, Peking University, Beijing, China (X.Z., W.X., Y.W.).
Background: Although the information on the validation status of electronic sphygmomanometer (ES) devices in use in health care institutions and households is much more clinically relevant than that of ES models available on the market, it remains insufficient.
Methods: A national survey was conducted across all administrative regions of mainland China to assess the validation status of ESs. Fifty-eight cities were selected with stratification by municipality, provincial capital, and other cities, and health care institutions and households in each city were chosen by convenience to identify ES devices in use according to the study protocol.
