Objective: To explore the results of comprehensive geriatric assessment (CGA) among convalescent elderly population, so as to provide the basis for strengthening the health management service level for convalescent elderly population. Methods: A total of 200 elderly people who convalesced at Hangzhou Wuyunshan Hospital from January 2021 to December 2023 were selected as the research subjects. The basic information, physical condition, psychological status, functional status, and social environment of the elderly were investigated using the CGA protocol. The basic characteristics of the elderly, physical conditions such as medication adherence, pain, malnutrition and frailty, psychological conditions such as cognitive function, anxiety symptoms and depression symptoms, functional conditions such as fall risk and social support level and social environment assessment results were analyzed. Results: Among the 200 elderly individuals, 58.00% were male, 44.50% were aged 70 to <80 years, 58.00% had an education level of high school or above, 55.00% were unmarried, 61.50% were childless, and 60.50% had basic medical insurance for employees. In terms of physical condition, 59.00% had comorbid chronic diseases, 40.50% used multiple medications, and the incidences of poor medication adherence, pain, malnutrition, and frailty were 22.50%, 10.00%, 54.00%, and 36.00%, respectively. Regarding psychological status, the incidences of impaired cognitive function, anxiety symptoms, and depressive symptoms were 57.00%, 89.50%, and 91.00%, respectively. In terms of functional status and social environment, 90.00% had a risk of falling, and 31.00% had a high level of social support. Univariable analysis showed that elderly individuals aged ≥80 years and those with an education level of primary school or below had higher incidences of poor medication adherence during convalescence; elderly individuals with poor medication adherence had a higher incidence of pain; and elderly individuals with impaired cognitive function, anxiety symptoms, and depressive symptoms had higher incidences of malnutrition (all P<0.05). Conclusions The physical condition and psychological status of convalescent elderly individuals are relatively poor, with a high risk of falling and insufficient levels of social support. Poor medication adherence is associated with advanced age and lower education levels, while malnutrition is associated with impaired cognitive function, anxiety symptoms, and depressive symptoms. Comprehensive health management for convalescent elderly population should be strengthened, and personalized health management services should be provided to improve their quality of life and sense of well-being.

BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder worldwide, causing dementia and affecting millions of individuals. One prominent characteristic in the brains of AD patients is glucose hypometabolism. In the context of galactose metabolism, intracellular glucose levels are heightened. Galactose mutarotase (GALM) plays a crucial role in maintaining normal galactose metabolism by catalyzing the conversion of β-D-galactose into α-D-galactose (α-D-G). The latter is then converted into glucose-6-phosphate, improving glucose metabolism levels. However, the involvement of GALM in AD progression is still unclear. In the present study, we found that the expression of GALM was significantly increased in AD patients and model mice. Genetic knockdown of GALM using adeno-associated virus did not change the expression of amyloid precursor protein (APP) and APP-cleaving enzymes including a disintegrin and metalloprotease 10 (ADAM10), β-site APP-cleaving enzyme 1 (BACE1), and presenilin-1 (PS1). Interestingly, genetic overexpression of GALM reduced APP and Aβ deposition by increasing the maturation of ADAM10, although it did not alter the expression of BACE1 and PS1. Further electrophysiological and behavioral experiments showed that GALM overexpression significantly ameliorated the deficits in hippocampal CA1 long-term potentiation (LTP) and spatial learning and memory in AD model mice. Importantly, direct α-D-G (20 mg/kg, i.p.) also inhibited Aβ deposition by increasing the maturation of ADAM10, thereby improving hippocampal CA1 LTP and spatial learning and memory in AD model mice. Taken together, our results indicate that GALM shifts APP processing towards α-cleavage, preventing Aβ generation by increasing the level of mature ADAM10. These findings indicate that GALM may be a potential therapeutic target for AD, and α-D-G has the potential to be used as a dietary supplement for the prevention and treatment of AD.

OBJECTIVE To design and synthesize novel α-naphthylthiol amino acid ester lysine specific demethylase 1(LSD1) inhibitors, evaluate their inhibitory activity with selectivity against LSD1, and explore their binding mechanism through molecular docking and dynamics simulation. METHODS Based on the binding mode of hit compound 3a with LSD1, the α- naphthyl mercapto amino acid ethyl ester small molecule compound were designed by fixing the planar hydrophobic naphthyl ring in the structure, while introducing hydrophilic amino fragment, and they were prepared through a multi-component one-pot cascade reaction. All the compounds were evaluated for their inhibitory activity against LSD1 at concentrations of 5.0 and 1.0 μmol·L–1 using the LSD1 screening platform of research group. The most potent compound was tested for its IC50 value and enzyme selectivity over MAO-A and MAO-B, and its binding mode was investigated through molecular docking and dynamics simulation. RESULTS A total of 13 compounds were obtained, all of which exhibited significant inhibitory effects on LSD1. Among them, nine compounds showed an inhibitory rate of over 50.0% against LSD1 at a concentration of 1.0 μmol·L–1, while compound 3l displaying the best activity with an IC50 value of 0.17 μmol·L–1, 174 times higher than the positive control. It also showed excellent selectivity towards MAO-A and MAO-B. Molecular docking and dynamics simulations indicated that compound 3l inhibited the activity of LSD1 through multiple interactions. CONCLUSION The structures of α-naphthylthiol amino acid ester can serve as lead compounds or active fragments, laying a solid foundation for the subsequent design of LSD1 inhibitors based on structure-oriented drug design.

To achieve the goals of carbon peak and carbon neutrality (double carbon), China has been updating and developing low-carbon coal-fired power generation technology. While reducing carbon dioxide emissions, it has achieved a significant reduction in emissions of pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides. However, at the same time, with the relative increase in emissions of certain pollutants such as sulfur trioxide, ammonia, and volatile organic compounds, the types and proportions of pollutant emissions have changed. This study summarized the technological improvements in coal-fired power generation both domestically and internationally, as well as the types and proportions of pollutants emitted by different coal-fired power generation modes. It also reviewed the epidemiological research progress on the impact of pollutants emitted from coal-fired power generation on the cardiopulmonary health of the population, expounded environmental impact of different coal-fired power models, and analyzed the changes in population exposure load and cardiopulmonary health benefits of low-carbon coal-fired power generation emissions, aiming to provide references for achieving carbon reduction and emission reduction goals and protecting the health of the population.
