OBJECTIVE:
To investigate the detection patterns, clinical phenotypic characteristics, and differences in diagnostic timeliness of Klinefelter syndrome (KS) across prenatal and postnatal stages, with an aim to provide a basis for optimizing strategies for early screening, diagnosis, and intervention.
METHODS:
A retrospective study was conducted to analyze data from two phases. The prenatal diagnosis group included 33,302 pregnant women who underwent amniocytic karyotyping due to advanced maternal age, abnormal ultrasound findings, or high-risk non-invasive prenatal testing (NIPT). The postnatal diagnosis group included 52,101 patients who underwent peripheral blood karyotyping due to primary infertility, abnormal external genitalia, or growth and developmental abnormalities. Additionally, medical histories of adult diagnosed patients were reviewed retrospectively to identify early occult symptoms. This study was approved by the Medical Ethics Committee of Chengdu Women's and Children's Central Hospital (Ethics No.: LCYJ-2025-030).
RESULTS:
In the prenatal group, 96 cases of KS were detected (detection rate 0.29%). The primary indications for referral were NIPT indicating sex chromosome abnormalities (45.83%), advanced maternal age (16.66%), and ultrasound abnormalities (17.70%). In the postnatal group, 128 cases of KS were detected (detection rate 0.25%). Clinical presentations were primarily primary infertility/azoospermia (77.34%), and the patients were predominantly adults (84.40%). Retrospective analysis revealed that adult patients presented with specific physical signs that had been overlooked during childhood.
CONCLUSION
As KS lacks typical early clinical manifestations, diagnosis is often delayed until adulthood when reproductive needs arise, showing a pattern of "passive detection" and resulting in missed opportunities for optimal intervention. By conducting a comparative analysis of prenatal diagnostic data and postnatal retrospective data, a risk association model linking prenatal screening indications with childhood-specific signs was developed. This study has provided empirical evidence for establishing a multidisciplinary, full life-cycle management system of "screening ~ diagnosis ~ monitoring ~ intervention" helping to shift from "passive detection in adulthood" to "proactive management across the entire life course," and laid a foundation for improving early diagnosis rate and long-term quality of life for patients.

Objective To investigate the incidence trends and influencing factors of non-alcoholic fatty liver disease (NAFLD) -related cirrhosis in China, predict future disease burden, and provide evidence for public health prevention strategies. Methods Based on the Global Burden of Disease (GBD) 2021 database, we employed joinpoint regression analysis to analyze NAFLD-related cirrhosis trends in China from 1990 to 2021, quantified influencing factors using age-period-cohort modeling, and predicted future incidence through Bayesian age-period-cohort analysis. Results The age-standardized incidence rates (ASIRs) of NAFLD-related cirrhosis showed a persistent increase from 1990 to 2021, with annual percentage changes (APCs) of 0.70% for male and 0.79% for female(both P<0.05). Age-effects revealed a U-shaped variation pattern, peaking in the 60-69 age group. Period effects indicated an incidence peak during 2017-2021. Cohort effects showed the most prominent risk in the 1992-1996 birth cohort. Projections suggested ASIR would further increase to 578.40 and 930.61 per 100 000 population for males and females, respectively, by 2030. Conclusions The disease burden of NAFLD-related cirrhosis continues to worsen in China, with future incidence rates projected to keep rising. Priority attention should be given to middle-aged and elderly populations and sex differences, with targeted prevention and control measures needing to be developed.

The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) issued the ICH E6(R3): Guideline for Good Clinical Practice on January 14, 2025, which will enhance the speed and quality of global clinical trials, including those in China. As the ethical, scientific and quality standards for global drug clinical trials, the highlights of the revision in the ICH E6 (R3) include encouraging innovation to improve efficiency and quality, motivating research participants to participate in the design and implementation of clinical trials throughout the process, emphasizing quality originating from design and based on the quality management of risks, as well as underlining proportionality and standalone chapter to data governance. ICH E6 (R3) adopts an appendix and appendix structure, enabling future revisions to be more convenient and efficient. ICH E6 (R3) restructures the principles section, adding two new principles and reducing the total from 13 to 11, while incorporating extensive explanatory notes. Major revisions also encompass multiple aspects, including regular review by ethics committees to ensure the safety, rights and interests, and well-being of research participants; diversification of informed consent methods, refinement of its processes, and clarification of detailed rules for minors’ consent; qualifications, authorization, and oversight of investigators and their service providers; risk-proportionate design and implementation by sponsors; joint data governance by investigators and sponsors; and the addition and revision of terms, along with updates to three appendices. The design, implementation, and review of drug clinical trials in China are increasingly aligning with international standards. ICH E6 (R3) will accelerate the revision of China’s Guideline for Good Clinical Practice, promote the speed and quality of drug research and development, and further facilitate the internationalization of China’s new drug research and development.

Objective:To predict the monthly incidence of hemorrhagic fever with renal syndrome (HFRS) in Hebei Province by using the generalized additive model (GAM).Methods:The incidence data of HFRS in Hebei from 2006 to 2020 were collected, and the correlation coefficients between meteorological factors and the monthly incidence of HFRS in Hebei were analyzed by Spearman's correlation, and the meteorological factors were lagged by 0-6 orders, and those with the largest absolute values of the correlation coefficients were screened to be included in the multifactorial GAM to evaluate the effects of meteorological factors.Results:The monthly incidence of HFRS had the strongest correlation with monthly mean air temperature at lag order 2, monthly mean wind speed at lag order 0, monthly mean sunshine at lag order 4, monthly mean precipitation at lag order 2 and monthly mean humidity at lag order 1, which were diagnosed by the variance inflation factor and included in the multifactorial GAM, and the results showed significant differences among the factors (all P<0.001), and they showed non-linear relationships with the monthly incidence of HFRS. Mean monthly temperature was an important factor influencing HFRS incidence. Mean monthly air temperature, mean monthly sunshine and mean monthly wind speed were negatively associated with HFRS incidence, whereas mean monthly precipitation and mean monthly humidity were positively associated with HFRS incidence. Conclusions:There was a complex non-linear relationship between meteorological factors and the incidence of HFRS. GAM incorporated with lagged meteorological factors can be used to predict the incidence of HFRS in Hebei.
