Objective To explore the predictive value of the modified frailty index-11 (mFI-11) for postoperative complications in elderly lung cancer patients undergoing robot-assisted lobectomy. Methods Clinical data were retrospectively collected from lung cancer patients aged ≥65 years who underwent robot-assisted lobectomy at the Department of Thoracic Surgery, Gansu Provincial Hospital, from January 2022 to June 2025. Based on the optimal grouping threshold of 0.27 in previous studies for the mFI-11 score, patients were divided into a frail and a non-frail group. Postoperative complications of the two groups were analyzed, and multivariable logistic regression was used to assess the relationship between mFI-11 and postoperative complications. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive efficiency of mFI-11 for postoperative complications. Results A total of 161 patients were included, with 77 males and 84 females, and an average age of (68.48±2.90) years. Among them, 103 (64.0%) patients were in the non-frail group and 58 (36.0%) in the frail group. Differences between the two groups in terms of independent functional status, hypertension requiring drug control, history of type 2 diabetes, history of chronic obstructive pulmonary disease, American Society of Anesthesiologists classification, and tumor staging were all statistically significant (P<0.05). The length of postoperative hospital stay in the frail group was longer than that in the non-frail group [5.50 (5.00, 8.25) d vs. 5.00 (4.00, 5.00) d, P<0.001]. The incidence rates of general respiratory diseases (25.9% vs. 8.7%), hypoproteinemia (15.5% vs. 4.9%), arrhythmia (12.1% vs. 1.9%), bronchopleural fistula (5.2% vs. 0.0%), transfer to ICU for severe complications (10.3% vs. 1.0%), and readmission within 30 days after discharge (12.1% vs. 1.9%) were all higher in the frail group compared to the non-frail group (P<0.05). Multivariable logistic regression analysis found that mFI-11 had a good predictive efficiency for postoperative complications: general respiratory diseases [area under the curve (AUC)=0.759], hypoproteinemia (AUC=0.723), arrhythmia (AUC=0.795), transfer to ICU for severe complications (AUC=0.713), and readmission within 30 days after discharge (AUC=0.702). Conclusion mFI-11 can effectively predict postoperative complications in elderly lung cancer patients undergoing robot-assisted lobectomy and can serve as an objective indicator for identifying high-risk elderly lung cancer patients.

Objective:To systematically evaluate the qualitative study on real experiences of HIV/AIDS adolescents transitioning to adult healthcare.Methods:The qualitative research on the real experiences of HIV/AIDS adolescents transitioning to adult healthcare was electronically searched in PubMed, Web of Science, CINAHL, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc. The search period was from January 1, 2010, to November 5, 2024. The methodological quality of the included literature was evaluated according to the Joanna Briggs Institute Center for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research. The results were synthesized through the aggregate integration method.Results:A total of 11 articles were included, 52 outcomes were distilled, and similar outcomes were grouped into nine new categories, which were synthesized to form three integrative outcomes (attitudes toward transitioning to adult healthcare, multiple dilemmas faced in transitioning to adult healthcare, and need for comprehensive support during transition to adult healthcare) .Conclusions:HIV/AIDS adolescents have complex attitudes about transitioning to adult healthcare and face multifaceted challenges in the transition process. Healthcare professionals should pay attention to the real experiences of adolescents during the transition period and work with parents and peers to provide holistic support, and meet the diverse needs of adolescents.

Objective:To systematically integrate the real experience of professional caregivers in the medical transition of adolescents with chronic diseases.Methods:Computerized searches were conducted in databases including Cochrane Library, PubMed, Web of Science, CINAHL, Embase, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc for qualitative studies on the real experience of professional caregivers involved in the medical transition of adolescents with chronic diseases. The search timeframe was from the inception of the database until September 11, 2024. The quality of the included studies was assessed using the criteria for evaluating the qualitative research quality of the Australia Joanna Briggs Institute Evidence-Based Health Care Centre. Meta-synthesis was employed to synthesize the results.Results:A total of ten studies were included, yielding 42 research results that were categorized into 11 themes. The final integrated findings were divided into three categories: professional caregivers' attitudes towards medical transition, barriers to medical transition for adolescents with chronic diseases, and factors facilitating medical transition for adolescents with chronic diseases.Conclusions:Professional caregivers' attitudes towards the medical transition of adolescents with chronic diseases are complex, with a perception of various barriers to the transition. It is essential for healthcare administrators to pay attention to these issues and implement targeted interventions. Furthermore, improving the transition service process will support adolescents in making a smooth and successful transition to the adult healthcare system.

The Maillard reaction is a complex process in which amine compounds such as amino acids， peptides， and proteins undergo condensation， polymerization， and other reactions with carbonyl compounds such as reducing sugars， ketones， and aldehydes at room temperature or under heating conditions， ultimately producing substances such as melanoidins and aromatic compounds. The processing of traditional Chinese medicine（TCM） often involves heating and the addition of auxiliary materials， providing complete conditions for the occurrence of the Maillard reaction. The Maillard reaction is affected by various factors such as temperature， pH， moisture， substrate， reaction time and pressure， the progress of the reaction also affected by different processing technologies of TCM and the addition of different excipients. The Maillard reaction involves multiple substances， most of which have significant physiological activity or toxicity， affecting the efficacy and pharmacological effects of TCM. It can also produce various flavor substances and browning products that change the flavor and color of TCM. The Maillard reaction mechanism， influencing factors， related components， and the impact of Maillard reaction on various aspects of TCM processing are reviewed from multiple perspectives in this article， providing reference for the further improvement of processing mechanism and quality control of TCM.

Objective:To evaluate the diagnostic performance of resting echocardiography in detecting severe coronary artery stenosis.Methods:A total of 136 patients with suspected coronary artery disease（CAD）who presented to Sichuan Provincial People's Hospital between January 2021 and December 2024 were prospectively enrolled. All patients underwent both coronary computed tomography angiography（CCTA）and transthoracic echocardiography within one week. Based on CCTA results，the patients were divided into non-severe stenosis group（ n=78）and severe stenosis group（ n=58）. Echocardiographic parameters including left atrial maximum volume（LAVmax），left ventricular global longitudinal strain（GLS），left ventricular longitudinal strain of endo-myocardium，mid-myocardium，epi-myocardium（LSendo，LSmid，LSepi），early diastolic mitral inflow velocity（E），early diastolic mitral annular velocity of the lateral and septal walls（e'），and E/e' were measured. Predictive factors for severe coronary stenosis were identified using LASSO regression，and a nomogram model was developed via multivariate Logistic regression. Model performance was evaluated using ROC curves，calibration curves，and decision curve analysis. Results:Multivariate Logistic regression analysis revealed LSendo，LAVmax，and E/e' as independent predictors of severe coronary artery stenosis. The nomogram constructed based on these predictors achieved an area under the curve of 0.798（95% CI=0.723-0.873），with sensitivity and specificity of 0.756 and 0.759，respectively. Conclusions:The resting echocardiography-based nomogram model demonstrates good diagnostic efficacy for severe coronary artery stenosis. It may serve as a noninvasive tool to assist in risk stratification and clinical decision-making in patients with suspected CAD.

Objective:To investigate the effects of short-term olfactory training and visual stimulation on olfactory recognition function and quality of life in patients following functional endoscopic sinus surgery (FESS).Methods:A total of 80 patients who underwent FESS in the Department of Otorhinolaryngology Head and Neck Surgery at the Affiliated Hospital of Xuzhou Medical University between December 2023 and February 2024 were enrolled in this study. The cohort comprised 67 males and 13 females, aged from 17 to 75 years. Participants were randomly allocated to either a control group ( n=40) or an experimental group ( n=40). The participants in control group received routine postoperative management, including nasal irrigation, oral antibiotics and glucocorticoids, topical budesonide nasal spray, and hypertonic saline solution for 12 weeks. In addition to the standard care, the participants in experimental group underwent olfactory-visual stimulation training starting 24 hours postoperatively, lasting for 2 weeks. The olfactory identification test (OIT), visual analogue scale (VAS) for olfaction and Questionnaire of Olfactory Disorders of Life (QOD-QoL, hereafter referred to as QOD) were administered preoperatively. Follow-up assessments were performed 2 weeks and 3 months postoperatively, with the same tests repeated. Data were analyzed using SPSS 27.0 and GraphPad Prism 7 statistical software. Results:There was no significant difference in preoperative OIT, VAS, and QOD scores between the two groups. The olfactory recognition function of some patients was improved after removing the packing material 24 hours after FESS surgery. The OIT scores of 2 weeks post-surgery were significantly higher than preoperative values in both groups (the experimental group Z=-4.73, P<0.001; the control group Z=-4.73, P<0.001). Participants in both groups showed improvements in olfactory VAS and QOD scores (experimental group Z value was -2.88 and -5.45, P<0.01 and<0.001, respectively; the control group Z value was -4.42 and -5.50, respectively, both P<0.001). However, there was no significant difference in the VAS score between the two groups ( Z=-0.68, P=0.499). The paticipants in experimental group showed greater improvement in OIT and greater reduction in QOD scores compared to the control group ( Z=-2.19, P=0.029; Z=-2.99, P=0.003). There was no significant difference in the decrease of olfactory VAS between the two groups ( Z=-0.02, P=0.988). There were no statistically significant differences of all patients in VAS, OIT and QOD scores at 2 weeks and 3 months after surgery (experimental group Z value was -0.91, -0.90 and -1.43, respectively, all P>0.05; control group Z value was -1.21, -0.84 and -0.91, respectively, all P>0.05). At 3 months post-surgery, the OIT scores in the experimental group were higher, the QOD scores were lower than those in the control group ( Z=-2.89, P=0.004; Z=-2.87, P=0.004). Conclusion:Short-term olfactory-visual stimulation training in the early postoperative period of FESS significantly improves the olfactory recognition function and enhances the quality of life of patients.
