Case Reports
Normal sperm quality despite partial deletion of sY84 in the AZFa region: A case report.
The complete absence of the azoospermia factor A (AZFa) region typically results in nonobstructive azoospermia. Partial deletions of the AZFa region are particularly noteworthy due to the limited and enigmatic reports of partial deletions in the AZFa region. Here, we present a rare case report of partial deletion of sY84 in the AZFa region but exhibiting normal sperm quality. The aim of this case report is to gain a deeper insight into the impact of AZFa region deletion on male fertility and to guide future clinical decisions and treatment strategies. ⋯ Our findings contribute to expanding our knowledge of the AZFa region. A sY84 deficiency in the AZFa region may not lead to spermatogenesis failure and may potentially be one of the factors causing recurrent miscarriages, which needs to be confirmed by further data.

Observational Study
Assessment of health literacy and HPV knowledge among university students: An observational study.
Health literacy (HL) level is related to promotion of health, improved health behaviors, and early diagnosis of diseases, as well as the appropriate use of health services. Human papillomavirus (HPV) vaccination is the primary method of protection against cervical cancer and recommended for women aged 9 to 27. This study aims to assess the university students' knowledge about HPV and the association between HL and HPV vaccination. ⋯ Participants with higher levels of HPV knowledge (P = .034) and total HPV-KS score (P = .025) were statistically significantly higher in students with adequate/excellent HL. Our results reveal that knowledge about HPV vaccination is closely related to HL levels. Educational interventions on HL may be considered to increase HPV vaccination rates.

Observational Study
Association between wait time of central venous pressure and 28-day mortality in critically patients with acute pancreatitis: A restrospective cohort study.
Hemodynamic management is crucial in patients with acute pancreatitis. Central venous pressure (CVP) is widely used to assess volume status. Our aim was to determine the optimal time window for obtaining CVP measurements to prevent adverse outcomes in patients. ⋯ Univariate and multivariate Cox regression analyses revealed a significantly increased risk of 28-day mortality in patients from the delayed CVP monitoring group compared to those who underwent early CVP measurements (HR = 2.87; 95% CI: 1.35-6.13; P = .006). Additionally, consistent results were observed for the risks of 90-day mortality (HR = 1.91; 95% CI: 1.09-3.35; P = .023) and 1-year mortality (HR = 1.84; 95% CI: 1.09-3.10; P = .023). In the ICU, an extended waiting time for CVP measurements in patients with acute pancreatitis was associated with an increased risk of 28-day mortality.

This study aims to investigate the relationship between Corona Virus Disease 2019 (COVID-19) cognition, social support, and mental health among pregnant women proposed for undergoing interventional prenatal diagnosis in Sichuan Province during the COVID-19 pandemic. A total of 2270 pregnant women (2232 valid) who were proposed to undergo interventional prenatal diagnosis at a tertiary hospital prenatal diagnosis center in Sichuan Province from January to December 2022 were selected by Convenience sampling and surveyed using a self-administered general information questionnaire, social support rating scale, mental health questionnaire (including: Self-Rating Anxiety Scale, Self-Rating Depression Scale), and self-administered COVID-19 cognition questionnaire. Structural equation modeling showed that social support negatively predicted anxiety (β = -0.34, t = -14.98, P < .001) and negatively predicted depressive status (β = -0.21, t = -9.57, P < .001); COVID-19 cognition negatively predicted anxiety (β = -0.76, t = -5.34, P < .001) and depression (β = -0.40, t = -2.99, P < .01); anxiety positively predicted anxiety (β = 0.73, t = 37.34, P < .001). ⋯ The fit indices of the model were: CMIN/DF = 3.071, GFI = 0.999, AGFI = 0.993, CFI = 0.999, RMSEA = 0.030, NFI = 0.998, and TLI = 0.992, indicating that the model had a good fit and the model was scientifically valid. Pregnant women in Sichuan province who are to undergo prenatal interventional diagnosis have a medium level of COVID-19 awareness, and their level of COVID-19 awareness and social support will directly affect their anxiety and depression level, and their anxiety level will also affect their depression level. We should give more attention to pregnant women, especially those in particular situations such as advanced age, poor maternal history, family history of genetic disease, etc, they should be given adequate care and social support, and multiple channels and types of health education should be provided for the COVID-19 to improve the pregnant women's knowledge of COVID-19, which is important for improving the mental health of pregnant women.

Osteosarcoma (OS) is the most common type of malignant bone tumor, that poses a serious threat to the lives and health of children and adolescents. Traditional Chinese medicines (TCM) have gained attention for treating OS because of their potent anti-cancer effects and fewer side effects. It is commonly understood that Gynostemma pentaphyllum (Thunb.) Makino (GP) exhibits inhibitory effects on most tumors. ⋯ Molecular docking and molecular dynamics simulations show that a high affinity between quercetin and these targets, especially with the combination of TNF free energy (Δ Gbind) minimum, MM/PBSA and MM/GBSA is 42.85 kcal/mol, respectively, and 45.29 kcal/mol. The active ingredients Rhamnazin and Quercetin in Gypenoylum play a therapeutic role in OS through several key targets and pathways. This study provides ideas and references for further research on drug development.
