Background: Anti-Müllerian hormone (AMH) is used for evaluating gonadal development and testicular function. We aimed to establish AMH reference intervals and to determine the correlations between AMH level and age, body mass index (BMI), and follicle stimulating hormone (FSH), luteinizing hormone (LH), and total testosterone (TT) levels in healthy Chinese boys.
Methods: Serum AMH levels of 2,009 healthy boys (age, 0-14 years), recruited between October 2017 and April 2019, were determined using the Beckman Access 2 automated chemiluminescence immunoassay. Single-year-specific median, mean, and standard deviation (SD) of AMH and effects of age, BMI, FSH, LH, and TT on the AMH level were analyzed.
Results: The median and mean ± SD values of AMH increased slightly after birth. Serum AMH values decreased sharply at 2 years of age and were 6-7% of the birth level at 12 years, after which they remained low. Age-specific AMH reference intervals were established. Significant negative correlations were observed between AMH level and age (r = -0.75, P < 0.001); serum AMH levels were moderately negatively correlated with BMI (r = -0.35, P < 0.001), FSH (r = -0.37, P < 0.001), and TT (r = -0.45, P < 0.001) levels; and correlation with LH (r = -0.18, P < 0.001) was the weakest. In contrast, correlations between AMH and the LH/FSH ratio were not observed.
Conclusion: We established single-year-specific reference intervals for AMH in Chinese boys. Our findings revealed the changes in AMH secretion during normal male growth, and may provide a basis for the clinical use of AMH.

Background: The current management of psoriasis does not differentiate between young and old patients in selecting the safest and/or most effective biologic.
Objectives: To explore the effect of age at treatment initiation in response to biologics in patients with moderate-to-severe psoriasis in the UK and Eire.
Methods: Data from patients registering to the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) from 2007-2024 on first course of Tumour Necrosis Factor (TNF), interleukin (IL) 12/13, IL-17 and IL-23 inhibitors (i) with at least 6 months' follow-up were included.

The aim was to explore the application value of dynamic electroencephalography (EEG) combined with brainstem auditory evoked potential (BAEP) in evaluating the degree of vascular stenosis and prognosis in patients with ischemic stroke (IS). This was a retrospective study using clinical data of patients with IS admitted to the First Affiliated Hospital of Chongqing Medical and Pharmaceutical College from March 2020 to March 2022. The degree of vascular stenosis and prognosis of patients were analyzed.

Introduction: There is an urgent need to improve the identification of psychosocial vulnerabilities in clinical practice (eg, stress, unstable living conditions) and examine their contribution to prenatal substance use, especially for legal substances such as alcohol, tobacco, and recently, cannabis.
Methods: We conducted a retrospective chart review of 1842 patients who completed the PROMOTE screening instrument during their first prenatal visit to outpatient clinics of a New York State health system in 6/2019-11/2020. The PROMOTE includes 18 core items to assess psychosocial vulnerabilities including the NIDA Quick Screen assessing past year substance use.

: Despite evidence that low vision rehabilitation (LVR) services can improve visual function in patients with neovascular age-related macular degeneration (nAMD), many patients are not directed to access these resources. This study was conducted to determine factors associated with LVR referral and to assess the visual outcomes from completed evaluations. : The study comprised a retrospective, cross-sectional analysis of patients with nAMD.

Background: The Multi-Specialty Working Group on the Recognition, Diagnosis, and Treatment of Primary Focal Hyperhidrosis developed evidence-based consensus criteria for diagnosing primary hyperhidrosis.
Objectives: To validate new questionnaire items for self-reported classification of primary hyperhidrosis based on the consensus criteria and to estimate the prevalence of primary hyperhidrosis.
Methods: This is a cross-sectional diagnostic accuracy study.
