OBJECTIVE: To investigate possible associations between physical function assessment scales, such as Short Physical Performance Battery (SPPB) and Berg Balance Scale (BBS), with all-cause mortality in acute decompensated heart failure (ADHF) patients. METHODS: A total of 108 ADHF patients were analyzed from October 2020 to October 2022, and followed up to May 2023. The association between baseline clinical characteristics and all-cause mortality was analyzed by univariate Cox regression analysis, while for SPPB and BBS, univariate Cox regression analysis was followed by receiver operating characteristic curves, in which the area under the curve represented their predictive accuracy for all-cause mortality. Incremental predictive values for both physical function assessments were measured by calculating net reclassification index and integrated discrimination improvement scores. Optimal cut-off value for BBS was then identified using restricted cubic spline plots, and survival differences below and above that cut-off were compared using Kaplan-Meier survival curves and the log-rank test. The clinical utility of BBS was measured using decision curve analysis. RESULTS: For baseline characteristics, age, female, blood urea nitrogen, as well as statins, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, or angiotensin receptor-neprilysin inhibitors, were predictive for all-cause mortality for ADHF patients. With respect to SPPB and BBS, higher scores were associated with lower all-cause mortality rates for both assessments; similar area under the curves were measured for both (0.774 for SPPB and 0.776 for BBS). Furthermore, BBS ≤ 36.5 was associated with significantly higher mortality, which was still applicable even adjusting for confounding factors; BBS was also found to have great clinical utility under decision curve analysis. CONCLUSIONS BBS or SPPB could be used as tools to assess physical function in ageing ADHF patients, as well as prognosticate on all-cause mortality. Moreover, prioritizing the improvement of balance capabilities of ADHF patients in cardiac rehabilitation regimens could aid in lowering mortality risk.

Given that ovarian stimulation is vital for assisted reproductive technology (ART) and results in elevated serum estrogen levels, exploring the impact of elevated estrogen exposure on oocytes and embryos is necessary. We investigated the effects of various ovarian stimulation treatments on oocyte and embryo morphology and gene expression using a mouse model and estrogen-treated mouse embryonic stem cells (mESCs). Female C57BL/6J mice were subjected to two types of conventional ovarian stimulation and ovarian hyperstimulation; mice treated with only normal saline served as controls. Hyperstimulation resulted in high serum estrogen levels, enlarged ovaries, an increased number of aberrant oocytes, and decreased embryo formation. The messenger RNA (mRNA)‍-sequencing of oocytes revealed the dysregulated expression of lysine-specific demethylase 6b (Kdm6b), which may be a key factor indicating hyperstimulation-induced aberrant oocytes and embryos. In vitro, Kdm6b expression was downregulated in mESCs treated with high-dose estrogen; treatment with an estrogen receptor antagonist could reverse this downregulated expression level. Furthermore, treatment with high-dose estrogen resulted in the upregulated expression of histone H3 lysine 27 trimethylation (H3K27me3) and phosphorylated H2A histone family member X (γ-H2AX). Notably, knockdown of Kdm6b and high estrogen levels hindered the formation of embryoid bodies, with a concomitant increase in the expression of H3K27me3 and γ-H2AX. Collectively, our findings revealed that hyperstimulation-induced high-dose estrogen could impair the demethylation of H3K27me3 by reducing Kdm6b expression. Accordingly, Kdm6b could be a promising marker for clinically predicting ART outcomes in patients with ovarian hyperstimulation syndrome.

OBJECTIVE: To assess the independent and combined effects of air pollutants, meteorological factors, and greenspace exposure on new tuberculosis (TB) cases. METHODS: TB case data from Shanghai (2013-2018) were obtained from the Shanghai Center for Disease Control and Prevention. Environmental data on air pollutants, meteorological variables, and greenspace exposure were obtained from the National Tibetan Plateau Data Center. We employed a distributed-lag nonlinear model to assess the effects of these environmental factors on TB cases. RESULTS: Increased TB risk was linked to PM _2.5, PM ₁₀, and rainfall, whereas NO ₂, SO ₂, and air pressure were associated with a reduced risk. Specifically, the strongest cumulative effects occurred at various lags: PM _2.5 ( RR = 1.166, 95% CI: 1.026-1.325) at 0-19 weeks; PM ₁₀ ( RR = 1.167, 95% CI: 1.028-1.324) at 0-18 weeks; NO ₂ ( RR = 0.968, 95% CI: 0.938-0.999) at 0-1 weeks; SO ₂ ( RR = 0.945, 95% CI: 0.894-0.999) at 0-2 weeks; air pressure ( RR = 0.604, 95% CI: 0.447-0.816) at 0-8 weeks; and rainfall ( RR = 1.404, 95% CI: 1.076-1.833) at 0-22 weeks. Green space exposure did not significantly impact TB cases. Additionally, low temperatures amplified the effect of PM _2.5 on TB. CONCLUSION Exposure to PM _2.5, PM ₁₀, and rainfall increased the risk of TB, highlighting the need to address air pollutants for the prevention of TB in Shanghai.

As a multifactorial chronic metabolic disorder with complex causes and serious health risks, obesity has drawn significant societal and medical attention. This article systematically reviewed the latest advancements in the clinical diagnosis and treatment of obesity. A disease-centered diagnosis and treatment concept has been proposed, which combines BMI and introduces a brand-new clinical diagnosis and treatment standard centered on fat content and functional disorders, such as new diagnostic markers like adipose tissue distribution, visceral adiposity, and waist-to-height ratio, to conduct a comprehensive assessment and lifespan management of patients. In recent years, novel biomarkers and artificial intelligence (AI)-assisted diagnosis have provided new tools for the diagnosis and treatment of obesity. In terms of treatment, combined therapy based on lifestyle and behavioral intervention has been widely recognized. The advent of new weight-loss drugs, such as glucagon-like peptide-1(GLP-1), minimally invasive techniques such as endoscopic sleeve gastrectomy(ESG), which reduced surgical risks, have provided possibilities for the treatment of obesity. The current concept of obesity management has become increasingly mature, feasible, and standardized. The construction principles of a weight management center, characterized by centralized management and individualized treatment, ensure the long-term stability of body weight and promote a healthy quality of life for patients with obesity.

Objective To investigate the relationship between serum levels of interferon-inducible protein 10(IP-10)and S100 calcium-binding protein A8(S100A8)and the prognosis of patients with severe pneumo-nia(SP).Methods A total of 315 SP patients admitted to the hospital from January 2021 to December 2023 were selected as the SP group,and 315 non-SP patients admitted to the hospital during the same period were selected as the non-SP group.According to the prognosis of SP patients 28 d after admission,they were divided into good prognosis group(199 cases)and poor prognosis group(116 cases).Enzyme-linked immunosorbent assay was used to detect serum IP-10 and S100A8 levels in SP patients.Pearson correlation analysis was used to analyze the correlation between IP-10,S100A8 levels and infection indicators[high-sensitivity C-reactive protein(hs-CRP),procalcitonin(PCT),interleukin-6(IL-6)].Multivariate Logistic regression was used to analyze the influencing factors of poor prognosis in SP patients.Receiver operating characteristic(ROC)curve was used to analyze the value of hs-CRP,PCT,IP-10 and S100A8 levels in predicting the poor prognosis of SP patients.Results The serum levels of IP-10,S100A8,hs-CRP,PCT and IL-6 in SP group were higher than those in non-SP group(P＜0.05).Paerson correlation analysis showed that serum IP-10 level in SP group was positively correlated with hs-CRP,PCT and IL-6(r=0.744,0.757,0.740,P＜0.05).S100A8 level was posi-tively correlated with hs-CRP,PCT and IL-6(r=0.769,0.718,0.744,P＜0.05).There were significant differences in oxygenation index,acute physiology and chronic health evaluation Ⅱ score,clinical pulmonary in-fection score and levels of hs-CRP,PCT,IP-10 and S100A8 between the poor prognosis group and the good prognosis group(P＜0.05).Multivariate Logistic regression analysis showed that hs-CRP,PCT,IP-10 and S100A8 were risk factors for poor prognosis in SP patients,and oxygenation index was a protective factor(P＜0.05).The ROC curve showed that the area under curve(AUC)of the combination of hs-CRP,PCT,IP-10 and S100A8 in predicting poor prognosis of SP patients was 0.965,which was greater than the AUC of the four alone(Zhs-CRP=4.009,ZPCT=4.022,ZIP-10=3.696,ZS100A8=3.309,P＜0.05).Conclusion The serum lev-els of IP-10 and S100A8 are up-regulated in SP patients.The combination of IP-10 and S100A8 has a high pre-dictive value for poor prognosis in SP patients.

Traditional airway management techniques may fail to provide adequate oxygenation and ventilation for high-risk patients in complex cases.As an extracorporeal life support(ECLS)technology,extracorporeal membrane oxygenation(ECMO)offers continuous oxygenation and homodynamic support for these patients and provides critical assistance in perioperative airway management.ECMO can be applied in various scenarios,including diffi-cult airways,complex airway surgeries and emergency airway management.It plays a vital role in ensuring peri-op-erative safety,optimizing surgical field exposure,reducing the risk of severe peri-operative complications and im-proving clinical outcomes.

Objective To explore the teaching effect of a"one-day"training model for basic application of periop-erative echocardiography for refresher anesthesiologists based on AR glasses and simulators.Methods The cardiac ultrasound teaching team of the Department of Anesthesiology at Peking Union Medical College Hospital designed a"one-day"teaching course for 60 trainees with no prior experience,based on AR glasses and simulators,covering basic applications of transthoracic echocardiography(TTE)and transesophageal echocardiography(TEE).We col-lected the scores of theoretical and practical assessments before and after the training and conducted a survey on trainee satisfaction and changes in clinical behavior post-training.Statistical analysis was performed using SPSS 23.0 software.Results The theoretical knowledge scores before and after the training were 52.35±12.33 and 81.20±22.78,respectively(P＜0.05);the practical assessment scores were 30.33±10.65 and 73.96±23.15,respectively(P＜0.05).Overall satisfaction rate was 96.66%(58/60).Conclusions The"one-day"teaching model for basic application of perioperative cardiac ultrasound based on AR glasses and simulators,as an introductory training model,can help beginners quickly master the core content at the entry level and lay a solid foundation for subsequent clinical application.

Objective To discuss the perioperative anesthesia management strategy for the surgical resection of rec-tal cancer in a patient with a rare neuromuscular disease-Facioscapulohumeral Muscular Dystrophy(FSHD)compli-cated by restrictive ventilatory dysfunction.Methods Clinical data of a patient with FSHD complicated by moder-ate-to-severe restrictive ventilatory dysfunction undergoing rectal cancer surgery were retrospectively collected;the clinical manifestations,complication,preoperative evaluation,intraoperative anesthesia management and postopera-tive pain treatment were analyzed and summarized.Results FSHD is a rare genetic disorder,and preopera-tive multidisciplinary evaluation is critical.In this case,total intravenous anesthesia was employed,with invasive arterial pressure monitoring,blood gas analysis,body temperature,sufficient analgesia,close respiratory monitoring and lung protective ventilation strategy after preoperative multidisciplinary evaluation.After thorough sputum suction,lung expansion,and complete recovery of muscle strength,the patient was successfully extubated;ensuring respiratory monitoring after surgery,sufficient analgesia was administered,and transferred to the ICU for monitoring,and ultimately discharged with satisfactory treatment results.Conclusions For patients with rare neuro-muscular diseases such as FSHD,thorough preoperative evaluation and optimization are essential.Clinicians should be aware of related complications,such as restrictive ventilatory dysfunction,and develop individualized anesthesia plans.Intraoperative monitoring,particularly of the respiratory and hemodynamic systems,should aim to prevent hypoxia and carbon dioxide retention,thereby reducing the risk of complications.

Objective To investigate the current status and training requirements of pain medicine among non-anes-thetic residents rotating in the Department of Anesthesiology at a tertiary hospital in Beijing.Methods A self-de-signed questionnaire of"pain medicine education requirements of rotating residents"was administered to each resi-dent on their first day of rotation,and voluntary responses were collected.Results A total of 108 questionnaires were collected(87.1％response rate),comprising 45 from surgical residents,42 from internal medicine resi-dents,and 21 from emergency and intensive care residents.The results showed that surgical residents encountered a higher prevalence of surgery-related pain as compared to internal medicine residents or emergency and intensive care residents(P＜0.001).Internal medicine residents experienced a greater incidence of inflamma-tory pain than surgical residents(P＜0.05)or emergency and intensive care residents(P＜0.01).All residents expressed continuing education requirements on pain management.Regarding training modalities,surgical residents favored medical course(86.7％);internal medicine residents preferred outpatient clinic rotation(88.1％);and emergency and intensive care residents preferred interventional treatment rotations(90.5％).Conclusions There are a wide need for continuing medical education on pain management.The training should be tailored diversely based on the specific clinical needs of each department to improve the overall quality of continuing medical educa-tion and accelerate the development of integrative pain management.

Objective To explore the practice and significance of the new course of"Enhanced Recovery after Sur-gery(ERAS)and Perioperative Management"for graduate students under multidisciplinary cooperation.Methods The Department of Anesthesiology collaborated with the Department of Clinical Nutrition,Department of Geriatrics and six related surgical departments to develop a course of 30 credit hours on"ERAS and Perioperative Manage-ment"in Peking Union Medical College Hospital.Researchers analyzed the teaching effectiveness of the course by collecting survey questionnaires and evaluating scheme report of ERAS case.Results Researchers found that ten graduates joined this course and they believed that learning improved their understanding of ERAS related knowl-edge,such as preoperative nutrition and functional state optimization,intraoperative volume and temperature man-agement,prevention of postoperative nausea and vomiting,and perioperative pain management.Students had high satisfaction with the course and believed that it would help improve their clinical literacy.Conclusions The new course of"ERAS and Perioperative Management"for graduates may support capacity building in terms of clinical logic and thinking about ERAS and promotion of skills for perioperative management.Our experience of graduates′training with"Enhanced Recovery after Surgery and Perioperative Management"course can be shared by other trainers of health institution of China.
