A unified consensus statement on medication-related osteonecrosis of the jaw (MRONJ) has not yet been established among the Asian member countries or regions of the Asian Federation of Osteoporosis Societies (AFOS). This study aimed to develop a consensus on MRONJ in patients with osteoporosis across these countries and regions. In this study, the term “Asia-Pacific” refers specifically to the Asian member countries and regions of AFOS. A structured survey consisting of nine MRONJ-related questions was distributed across 10 countries and regions to assess the level of agreement and summarize regional perspectives. In addition, a manual literature review and voting were conducted to evaluate the current evidence on MRONJ. The key aspects of MRONJ, including definition, staging, diagnosis, pathogenesis, risk factors, management, and prevention, were generally consistent among the AFOS countries and regions. The annual incidence and incidence rate of MRONJ associated with low-dose antiresorptive therapy in patients with osteoporosis ranged from 0.025% to 0.136% and 21 to 283 cases per 100,000 person-years, respectively. However, evidence regarding the benefits of drug discontinuation before dental surgery, such as tooth extraction, remains insufficient. Large-scale, multinational studies across AFOS countries and regions are warranted to determine the incidence of MRONJ better and evaluate the impact of antiresorptive drug discontinuation before dental procedures. These findings may contribute to the devel opment of effective evidence-based strategies for preventing MRONJ in patients with osteoporosis.

Objective To investigate the prevalence and related factors of sarcopenia among non–bedridden older adults in the community of Baoshan District using the China mini sarcopenia risk assessment 7 (C-MSRA-7) combined with Ishii scoring system. Methods The older individuals consulting at 20 community health stations in Baoshan District between April 2025 and June 2025 were enrolled. Data were collected using a general information questionnaire, a dietary and lifestyle habits survey, the C-MSRA-7, and the mini nutritional assessment-short form (MNA-SF). Handgrip strength and anthropometric measurements were also obtained. Individuals with both Ishii score and C-MSRA-7 results positive were classified into the sarcopenia risk group, while the remaining participants were assigned to the non–sarcopenia risk group. Differences in lifestyle habits, dietary patterns, and nutritional status between the two groups were compared. Results A total of 2 611 valid questionnaires were retrieved. Univariate analysis showed statistically significant differences in alcohol consumption, physical activity frequency, body mass index (BMI), nutritional status, activities of daily living, and regularity of three meals in sarcopenia risk group (n＝486) and non–sarcopenia risk group (n＝2 125, P<0.05). Logistic regression analysis showed that advanced age (75–84 years: OR＝2.55, 95%CI 2.03–3.21; ≥85 years: OR＝3.98, 95%CI 2.24–7.07), underweight status (OR＝2.19, 95%CI 1.50–3.19), weight loss＞2 kg (OR＝4.52, 95%CI 2.68–7.64) past 3 months, lack of regular physical activity (OR＝1.77, 95%CI 1.24–2.52) , and alcohol consumption (OR＝1.48, 95%CI 1.07–2.05) were independent risk factors for sarcopenia (P<0.05). Behaviors related to healthy diet, including daily milk consumption (OR＝0.40, 95%CI 0.30–0.52), regular three meals (OR＝0.56, 95%CI 0.41–0.78), and high-quality protein intake (OR＝0.70, 95%CI 0.52–0.94), were protective factors (P<0.05). Conclusions Sarcopenia among community–dwelling, non–bedridden older adults is closely associated with physical activity levels, dietary habits, and nutritional status. Early identification of individuals at risk, enhanced nutritional education, and timely implementation of nutritional interventions and exercise programs are recommended for this population.

Objective To propose an improved Bouc-Wen model to alleviate the nonlinear effect of the hysteresis displacement of piezoceramics and enhance the motion control accuracy of the nano-displacement platform.Methods Firstly,two fine-tuning parameters including the asymmetric term and the input bias term were added to the classical Bouc-Wen model to eliminate the deviation of the starting and ending positions of the hysteresis curve,so as to obtain an improved Bouc-Wen model simulating the hysteresis displacement characteristics of piezoceramics on the nano-displacement platform.Secondly,the parameters of the improved Bouc-Wen model were identified based on the particle swarm optimization algorithm,and an inverse feedforward structure was adopted to realize the linearized control of the output displacement.Finally,an experimental system was built to verify the linearized control effect of the improved Bouc-Wen model.Results The hysteresis curve of the improved Bouc-Wen model fitted the actual voltage-displacement curve of piezoceramics significantly better when compared with that of the traditional model,which had a 56%reduction in the fitting error and a 0.03 μm error between the desired and actual displacements during the linearized output control with a driving voltage of 0-60 V and a maximum travel of about 4 μm.Conclusion The improved Bouc-Wen model behaves well in hysteresis displacement fitting and linearized output control,and a new idea is provided for enhancing the motion control accuracy of the nano-displacement platform.[Chinese Medical Equipment Journal,2025,46(8):25-31]

Objective To examine the diagnosis and treatment of disseminated infection caused by Enterocytozoon bieneusi in a child with leukemia and improve the awareness of the pathogen in clinical and laboratory practice.Methods A case of disseminated infection caused by Enterocytozoon bieneusi in a child with leukemia in Shanghai Children's Hospital was retrospectively analyzed,including diagnosis and treatment details.Similar cases were identified from PubMed,Wanfang Data,VIP,and CNKI databases since database establishment until June 30,2024,using search terms"Enterocytozoon bieneusi".The relevant literature was reviewed.Results This child had acute lymphoblastic leukemia as the underlying disease and was admitted to hospital for antimicrobial treatment due to fever and abdominal discomfort.The case was considered bacterial infection complicated with Enterocytozoon bieneusi infection,confirmed by detection of Klebsiella pneumoniae in blood and detection of Enterocytozoon bieneusi in blood and ascites by metagenomic next-generation sequencing(mNGS).The treatment was switched to tigecycline plus trimethoprim-sulfamethoxazole at a sufficient dose,which resulted in resolution of symptoms.Six months later,the patient suffered from acute lymphoblastic leukemia and bone marrow depression,Enterocytozoon bieneusi disseminated infection,septic shock.Her family gave up treatment and the child died.Literature review indicated that most patients infected with Enterocytozoon bieneusi had underlying conditions such as organ transplantation,AIDS,and leukemia associated with poor immunity.The onset symptoms are diarrhea,abdominal discomfort,and fever.Enterocytozoon bieneusi was detected by using methods such as modified Masson's trichrome stain,fluorescent calcofluor white staining,molecular detection techniques,and immunofluorescence.The patients were treated with drugs such as albendazole,nitazoxanide,fumagillin,and trimethoprim-sulfamethoxazole.Conclusions Enterocytozoon bieneusi is an opportunistic pathogenic fungus that infects immunocompromised patients and can cause abdominal discomfort,diarrhea,fever,and even disseminated infection and death.Conventional laboratory methods cannot culture Enterocytozoon bieneusi.Molecular detection techniques can be used to identify the pathogen early.

Objective:To construct a dynamic competency assessment system suitable for standardized training of resident physicians in the department of pediatric infectious diseases, verify its teaching practice effectiveness, and enhance the core competence of specialist physicians.Methods:Based on the Delphi method, an evaluation system was constructed. Through two rounds of expert consultation ( n=20, authority coefficient Cr=0.889-0.895), 5 primary indicators, 13 secondary indicators, and 38 tertiary indicators were established, covering dimensions such as clinical thinking, operational skills, and professional ethics. The hierarchical and progressive design and dynamic feedback mechanism were adopted. Sixty residents were randomly divide into an observation group (dynamic evaluation system) and a control group (traditional evaluation). Differences between the two groups were compared in terms of short-term teaching effectiveness (e.g., OSCE assessment and Mini CEX score) and long-term clinical competencies (e.g., exit assessment pass rate and incidence of adverse events). SPSS 24.0 was used for t-test, Mann Whitney U test, and internal consistency test (Cronbach's alpha=0.89). Results:The observation group outperformed the control group in core specialty competencies and clinical practice outcomes. In terms of core specialty competencies, the observation group had a higher response speed score for pathogen results [(4.10±0.84) vs. (3.60±0.95), P=0.042]. This indicates that the dynamic evaluation system effectively enhanced the ability of trained physicians to quickly adjust treatment plans based on pathogenic evidence. The implementation rate of infection prevention and control standards and diagnostic accuracy were also higher in the observation group compared to the control group, reflecting the advantages of this system in standardizing clinical operations and improving diagnostic levels. In terms of long-term clinical competencies, the observation group showed significantly increased exit assessment pass rate and significantly decreased incidence of medical adverse events, further verifying the continuous promotion effect of the dynamic evaluation system on the clinical competence of trained physicians. Conclusions:The dynamic evaluation system constructed in this study can effectively enhance the core specialty competencies (e.g., pathogen response and infection prevention and control) and long-term clinical competence of residents in the department of pediatric infectious diseases, providing scientific basis for optimizing the training models of specialist physicians.

Aim To explore the relationship between serum levels of proprotein convertase subtilisin/kexin type 9(PCSK9),macrophage migration inhibitory factor(MIF)and the severity of coronary artery lesions in patients with coro-nary heart disease(CHD).Methods A cross-sectional study was conducted involving 139 patients with CHD and 69 control subjects who underwent coronary angiography during the same period,all of whom were admitted to the People's Hospital of Xinjiang Uygur Autonomous Region from November 2023 to May 2024.Clinical data and coronary angiography results were collected,and the severity of coronary artery stenosis was quantitatively assessed using the Gensini score.Pa-tients with the Gensini scores＞0 were classified into three groups based on tertiles:the mild stenosis group(1～18 points,54 cases),the moderate stenosis group(19～36 points,54 cases),and the severe stenosis group(＞36 points,54 ca-ses).Serum levels of PCSK9 and MIF were measured by ELISA kit.Results Serum levels of PCSK9 and MIF were significantly higher in the CHD group than those in the control group(P＜0.05).Multivariable Logistic regression analy-sis revealed that high levels of serum PCSK9 and MIF were independent risk factors for CHD.Spearman correlation analy-sis showed that serum PCSK9 and MIF levels were positively correlated with Gensini score(rs=0.619 6 and r,=0.411 4,both P＜0.001).Further subgroup analysis showed that serum total cholesterol and low density lipoprotein cholesterol lev-els were significantly increased in patients with high-level PCSK9,while patients with high-level MIF had higher inflamma-tory coefficients such as systemic inflammatory response index(SIRI)and systemic immune-inflammation index(SII)(all P＜0.05).Conclusion Serum levels of PCSK9 and MIF are positively correlated with the severity of coronary artery stenosis.High levels of serum PCSK9 and MIF are independent risk factors for CHD.

Aim To investigate the protective effects of resveratrol(RSV)on hypoxia/reoxygenation(H/R)-induced apoptosis in H9c2 cardiomyocytes and the un-derlying mechanisms.Methods A model of H/R was established in H9c2 cardiomyocytes.Cell apoptosis was determined by flow cytometry.The expressions of Bax,Bcl-2,cleaved caspase-3 and JAK2/STAT3 signa-ling pathway proteins were detected by Western blot.The inhibitor of JAK2,AG490,was used to assess the effect of RSV on H/R-induced apoptosis in H9c2 car-diomyocytes after inhibiting JAK2/STAT3 signaling pathway.Results RSV could effectively inhibit H/R-provoked cell apoptosis in H9c2 cardiomyocytes and increase the expression of p-JAK2 and p-STAT3.After AG490 intervention,the anti-apoptotic effect of RSV on H9c2 cardiomyocytes caused by H/R was significantly counteracted.Conclusions RSV can inhibit H/R-in-duced apoptosis in H9c2 cardiomyocytes through the activation of JAK2/STAT3 signaling pathway.
