Objective To compare the long-term survival outcomes of patients with T_1-2N₀M₀ duodenal neuroendocrine tumor (DNET) after endoscopic resection (ER) or surgical resection (SR). Methods Patients diagnosed with T_1-2N₀M₀ DNET between January 1, 2004, and December 31, 2015, were extracted from the SEER database. Kaplan-Meier survival curve and log-rank test were used to compare overall survival (OS) rate and cancer-specific survival (CSS) rate between patients undergoing ER or SR. Propensity score matching (PSM) was used to reduce grouping differences, and multivariate Cox regression was used to analyze factors affecting OS and CSS before and after PSM. Results A total of 656 patients were included, with 457 in ER group and 199 in SR group. Before PSM, there was no significant difference in the 5-year OS rate between the ER and SR groups (88.9% vs 89.6%), but there was a significant difference in the 5-year CSS rate (99.3% vs 96.9%, P＝0.017). Before PSM, multivariate Cox regression analysis showed advanced age was an independent risk factor for decreased OS (P＜0.001). After PSM, there was no significant difference between the ER group (n＝187) and SR group (n＝187) in 5-year OS rate (90.2% vs 88.9%) or CSS rate (98.9% vs 96.7%). After PSM, multivariate Cox regression also showed advanced age was an independent risk factor for decreased OS, while resection method was not an independent factor for OS or CSS. Conclusions There is no significant difference in OS or CSS after endoscopic treatment and surgical treatments for patients with T_1-2N₀M₀ DNET, and advanced age is an independent factor for OS.

OBJECTIVE: To investigate the short-and med-term clinical efficacy of unicompartmental knee arthroplasty(UKA)for the treatment of medial knee osteoarthritis (OA) in elderly patients with anterior cruciate ligament deficiency(ACLD). METHODS: A retrospective analysis was conducted on 31 patients aged over 75 years old with primary medial knee OA and ACLD who underwent UKA between January 2018 and December 2022. The cohort included 12 males and 19 females, aged from 75 to 91 years with an average age of (79.56±4.54) years, with 13 left knee, 16 right knee, and 2 bilateral knees. Clinical outcomes were assessed preoperatively and at final follow-up using the visual analogue scale (VAS), Hospital for Special Surgery(HSS) score, range of motion (ROM), hip-knee-ankle angle (HKA), and tibial component posterior slope angle (TCPSA). Complications such as infection, prosthesis wear, prosthesis loosening, and dislocation were also recorded. RESULTS: All 31 patients were followed up from 12 to 63 months with an average of (28.34±10.56) months. The average postoperative TCPSA was (4.83±1.31)° ranged from 2.5° to 6.8°. At the final follow-up, there was significant improvement in VAS (3.24±0.53) vs. (6.59±0.69), HSS score (85.19±4.45) vs. (64.38±5.94), ROM (118.83±5.38)° vs. (98.85±4.08)°, and HKA (176.83±5.16)° vs. (169.57±6.28)° compared to preoperative values (P<0.05). No cases of infection, prosthesis loosening, or dislocation were reported. CONCLUSION UKA provides favorable short-and mid-term outcomes for elderly patients with medial knee OA and ACLD . However, long-term clinical efficacy needs further investigation through extended follow-up.

Objective: To analyze the disease burden and trends of oral diseases among China’s elderly population (1990-2021) and provide evidence for developing targeted intervention strategies Methods : Using data from the Global Burden of Disease (GBD) 2021 study, we extracted prevalence, incidence, and disability-adjusted life years (DALYs) for oral conditions (permanent dental caries, edentulism, periodontal diseases, and other oral disorders) in individuals aged ≥60 years in China. Due to data limitations, other oral diseases only included DALYs and prevalence. Age-standardized rates (ASR)—including age-standardized prevalence rate (ASPR), age-standardized incidence rate (ASIR), and age-standardized DALYs rate (ASDR)--were calculated. Trends were assessed via Joinpoint regression using average annual percentage change (AAPC), stratified by sex and age groups (60-64, 65-69, 70-74, 75-79, 80-84, 85-89, 90-94, 95+ years). Results: From 1990 to 2021, China’s elderly population exhibited distinct trends in oral disease burden. Overall oral diseases showed declining ASDR and ASPR, yet ASIR slightly increased. Permanent dental caries demonstrated significant rises across ASDR, ASIR, and ASPR. Edentulism showed declining ASDR and ASPR alongside stable ASIR. 95+ age group saw rising rates. Periodontal diseases remained largely stable in ASDR and ASPR but experienced a slight ASIR decline. Other oral disorders showed mild ASDR decline and stable ASPR. Notably, sex and age disparities persisted. Women consistently bore higher burdens for overall oral diseases, caries, edentulism, and other oral diseases but lower periodontal disease rates compared to men. 85-89, 90-95, 95+ age group faced rising DALYs and prevalence for overall oral diseases, while all other age groups demonstrated declining trends in both DALYs and prevalence; for permanent caries, the 60-64 age group showed the largest increases in DALY rate, incidence, and prevalence; edentulism demonstrated the most pronounced and sustained rises in DALY rate and prevalence in the 95+ group, while declining most rapidly in the 60-64 age group; for periodontal disease, both DALY rates and prevalence declined in the 90-94 and 95+ age groups, but increased across all measures (DALY rate, incidence, and prevalence) in the 70-74 and 75-79 age group; other oral conditions exhibited relatively stable burden distributions or minor changes, with no significant age-specific shifting trends observed. Conclusion From 1990 to 2021, China’s elderly oral disease burden declined overall, but caries surged, edentulism improved, periodontal diseases stabilized, and other oral diseases slightly declined. Prioritizing older women and the adults aged 85+ is critical to addressing evolving oral health needs.

Lung cancer has the highest incidence and mortality among malignant tumors in China.Persistent subsolid nodules(SSNs)are closely associated with early-stage lung adenocarcinoma.Artificial intelligence(AI),as an emerging technology,is capable of performing in-depth analysis of large-scale imaging data through autonomous learning and possesses the ability to predict outcomes from new data,demonstrating great potential and application prospects in the assessment of SSNs.AI can not only effectively assist radiologists in diagnosis and treatment,but also improve work efficiency while reducing misdiagnosis and missed diagnosis rates.This review summarizes the recent applications and research progress of AI in the assessment of SSNs,to provide new insights for the diagnosis and treatment of SSNs.

OBJECTIVE: To assess the risk of aristolochic acid (AA)-associated cancer in patients with AA nephropathy (AAN). METHODS: A retrospective study was conducted on patients diagnosed with AAN at Peking University First Hospital from January 1997 to December 2014. Long-term surveillance and follow-up data were analyzed to investigate the influence of different factors on the prevalence of cancer. The primary endpoint was the incidence of liver cancer, and the secondary endpoint was the incidence of urinary cancer during 1 year after taking AA-containing medication to 2014. RESULTS: A total of 337 patients diagnosed with AAN were included in this study. From the initiation of taking AA to the termination of follow-up, 39 patients were diagnosed with cancer. No cases of liver cancer were observed throughout the entire follow-up period, with urinary cancer being the predominant type (34/39, 87.17%). Logistic regression analysis showed that age, follow-up period, and diabetes were potential risk factors, however, the dosage of the drug was not significantly associated with urinary cancer. CONCLUSIONS No cases of liver cancer were observed at the end of follow-up. However, a high prevalence of urinary cancer was observed in AAN patients. Establishing a direct causality between AA and HCC is challenging.

Objective The aim of this study was to investigate the prospective association between physical activity (PA),independently or in conjunction with other contributing factors,and osteoporosis (OP) outcomes. Methods The Physical Activity in Osteoporosis Outcomes (PAOPO) study was a community-based cohort investigation. A structured questionnaire was used to gather the participants' sociodemographic characteristics. Bone mineral density (BMD) measurements were performed to assess OP outcomes,and the relationship between BMD and OP was evaluated within this cohort. Results From 2013 to 2014,8,471 participants aged 18 years and older were recruited from Tangshan,China's Jidong community. Based on their PA level,participants were categorized as inactive,moderately active,or very active. Men showed higher physical exercise levels than women across the activity groups. BMD was significantly higher in the very active group than in the moderately active and inactive groups. Individuals aged>50 years are at a higher risk of developing OP and osteopenia. Conclusion The PAOPO study offers promising insights into the relationship between PA and OP outcomes,encouraging the implementation of PA in preventing and managing OP.

Bone organoids can simulate the complex structure and function of the bone tissues, which makes them a frontier technology in organoid researches. Bone organoids show a tremendous potential of applications in bone disease modeling, bone injury repair, and medicine screening. Although advancements have been made so far in constructing bone organoids with functional structures like mineralization, bone marrow, trabecular bone, callus, woven bone, etc, the researches in this field are confronted with numerous challenges such as lack of standardized construction strategies and unified evaluation criteria, which limits their further promotion and application. To standardize researches in bone organoids, the Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, the Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, the Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and the Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine organized related experts to formulate Expert consensus on the construction, evaluation, and application of bone organoids ( version 2024) based on an evidence-based approach. A total of 17 recommendations were put forth, aiming to standardize researches and clinical applications of bone organoids and enhance their value in scientific research and clinical practice.

OBJECTIVES: To investigate the impact of the different proportions of crescent formation on clinical manifestations and pathological features in children with immunoglobulin A vasculitis with nephritis (IgAVN). METHODS: The children with IgAVN were divided into no-crescent group (75 children), ≤25% crescent group (156 children), and >25% crescent group (33 children). RESULTS: Compared with the no-crescent group, the other two groups had significant increases in 24-hour urinary protein, urinary immunoglobulin G (IgG)/creatinine ratio, urine red blood cell count, fibrinogen, and neutrophil-lymphocyte ratio, a significant reduction in serum IgG, and a significantly higher proportion of children with low albumin and hypercoagulability, pathological grade III+IV or diffuse mesangial proliferation (P<0.05). Compared with the ≤25% crescent group, the >25% crescent group had significant increases in 24-hour urinary protein, urine red blood cell count, and fibrinogen, significant reductions in serum IgG and glomerular filtration rate, and a significantly higher proportion of children with diffuse mesangial proliferation, tubular atrophy or interstitial fibrosis (P<0.05). Compared with the no-crescent group, the >25% crescent group had significantly higher levels of total cholesterol, triglycerides, urea nitrogen, and serum creatinine (P<0.05). A reduction in serum IgG, hypercoagulability, an increase in 24-hour urinary protein, diffuse mesangial proliferation, and chronic tubulointerstitial lesions were influencing factors for the increase in the proportion of crescent formation (P<0.05). CONCLUSIONS For children with IgAVN, the higher proportion of crescent formation is associated with greater abnormalities in laboratory markers and more severe chronic tubulointerstitial lesions, and thus a detailed analysis of the proportion of crescent formation can better guide clinical treatment.

Objective:To systematically evaluate the relationship between thiazide diuretics and the risk of hip fracture in the elderly patients.Methods:The relevant databases at home and abroad were searched up to December 31, 2023 and case-control studies and cohort studies on the relationship between thiazide diuretics and the risk of hip fractures in the elderly patients were collected. Quality of the enrolled studies was evaluated by bias risk assessment tool of Newcastle-Ottawa Scale (NOS). RevMan 5.4 software was used for meta-analysis on related outcome indicators, and the effect sizes were odds ratio ( OR) and the 95% confidence interval ( CI). Funnel plots, Egger′s method and Begg′s method were performed using Stata 15.1 software to analyze the inclusion literature for publication bias. Results:A total of 18 studies were enrolled in the study, including 7 case-control studies and 11 cohort studies and involving 175 200 patients in the trial group (thiazide diuretics) and 1 574 989 in the control group (placebo or other medications). All 18 studies scored ≥5 on the NOS (15 articles of high quality and 3 articles of medium quality). The meta-analysis results indicated that the risk of hip fractures in the trial group was lower than that in the control group ( OR=0.82, 95% CI: 0.75-0.89, P<0.001). Subgroup analyses by study type and gender both revealed that thiazide diuretics were associated with a reduced risk of hip fractures in the elderly (adjusted OR in case-control studies was 0.78, 95% CI: 0.72-0.84, P<0.001; adjusted OR in cohort studies was 0.83, 95% CI: 0.74-0.93, P=0.002; adjusted OR in female was 0.78, 95% CI: 0.72-0.85, P<0.001; adjusted OR in male was 0.73, 95% CI: 0.68-0.80, P<0.001). The subgroup analysis of 11 large-sample studies (≥2 000 cases) indicated that thiazide diuretics were associated with a reduced risk of hip fractures in the elderly (adjusted OR=0.79, 95% CI: 0.72-0.87, P<0.001). However, 6 small-sample studies did not find the similar correlation. A combined analysis of studies that rigorously controlled for confounding factors revealed that thiazide diuretics were associated with a lower risk of hip fractures in the elderly ( OR=0.79, 95% CI: 0.74-0.84, P<0.001), and the combined results showed no heterogeneity ( P=0.72, I2=0%). Conclusions:Thiazide diuretics were associated with a reduced risk of hip fractures in the elderly patients. Based on a comprehensive assessment of the risks and benefits of medication for elderly patients, clinicians may prioritize thiazide diuretics as a component of combination therapy for eligible patients, which may be beneficial in reducing their risk of hip fractures.
