Objective:This study aims to provide insights into the clinical features of anti-melanoma differentiation-associated protein-5(MDA5)-positive dermatomyositis (MDA5-DM) patients with fatal outcomes, leveraging pathogenic microbiota metagenomic analysis, to guide the clinical assessment and treatment choices.Methods:From January 2020 to August 2023, deceased patients diagnosed with MDA5-DM were identified at the Department of Rheumatology and Immunology, the Second Affiliated Hospital of Xi ′an Jiaotong University. Clinical data were retrospectively collected and analyzed using Mann Whitney U test and Fisher ′s exact test to summarize risk factors and treatment assessment for MDA5-DM patients with fatal outcomes. Results:①The proportion of male patients was higher than females among MDA5-DM patients with fatal outcomes, which differed from the incidence pattern, possibly associated with smoking and gender proportions (6/11 vs. 0/7, P=0.037). ②94%(17/18) patients presented initially with elevated ferritin levels [(1 350±942)ng/ml] and CRP [(47±36)mg/L]. ③All patients (18/18) exhibited early involvement of the upper lung lobes, including multiple nodules in 9/18, ground-glass opacities in 5/18, and solitary nodules in 4/18. ④Metagenomic next-generation sequencing (mNGS) of bronchoalveolar lavage fluid was negative in 4/16 cases, with cytomegalovirus and pneumocystis jirovecii being the most commonly detected pathogens in 5/16 cases each. ⑤89%(16/18) of patients continued to have lymphocyte counts persistently <0.5×10 9/L irrespective of treatment. Conclusion:Smoking may have adverse effects on male MDA5 patients. Early involvement of the upper lobe of the lungs is more common in MDA5 antibody positive deaths, and persistent lymphocyte depletion is an important factor in poor response. Enhancing mNGS analysis of bronchoalveolar lavage fluid and vigilance towards cytomegalovirusand Pneumocystis jirovecii could provide valuable clinical guidance.

Objective To observe the value of ultrasonic parameters of diaphragm motion combined with BODE index for predicting acute exacerbation of chronic obstructive pulmonary disease(COPD).Methods Eighty COPD patients were retrospectively collected and divided into stable group(n=45)and acute exacerbation group(n=35).Ultrasonic parameters of diaphragm motion,including diaphragm excursion(DE)under quiet breathing(QB)and deep breathing(DB),i.e.DEQB and DEDB were measured.The general data,ultrasound parameters of diaphragm motion,and BODE index scores were compared between groups.Then logistic regression analysis was used to identify factors which could be used to independently predict acute exacerbations of COPD.The predicting performance of ultrasound parameters of diaphragm motion,BODE index and their combination were evaluated with receiver operating characteristic(ROC)curve and the area under the curve(AUC).Results Compared with stable COPD group,acute exacerbation group had higher BMI and BODE index scores(both P＜0.05),as well as larger DEQB but smaller DEDB(both P＜0.05).DEDB and BODE index were both independent predicting factors of acute exacerbation of COPD,while increased DEDB indicated decreased risk of acute exacerbation(OR[95％CI]=0.673[0.493,0.918],P＜0.05),whereas increased BODE index suggested higher risk(OR[95％CI]=3.678[1.061,12.746],P＜0.05).AUC for DEDB and BODE index alone for predicting acute exacerbation of COPD was 0.788 and 0.799,respectively,and of their combination was 0.979,significant higher than that of each alone(both P＜0.05).Conclusion Ultrasonic parameters of diaphragm motion could be used to evaluate diaphragm function in COPD patients.Combination of DEDB and BODE index had better performances in predicting acute exacerbation of COPD.

Objective To analyze the cognitive function and sleep quality of the elderly in Shanghai community, and explore the related influencing factors. Methods A stratified cluster random sampling method was used to select 8 community health centers in Shanghai for a questionnaire survey, including 3 677 elderly individuals who completed the “Comprehensive Health Status Survey of Elderly Residents in Shanghai” from September 2023 to November 2023. Basic information of the elderly was collected, including age, gender, education level, smoking, drinking, mahjong playing behavior, and exercise habits. The Pittsburgh sleep quality index (PSQI) was used to assess the sleep quality of the elderly, subjective cognitive decline (SCD) self-assessment questionnaire and Mini-Mental State Examination (MMSE) were used to evaluate cognitive function, while the Hamilton Anxiety Scale (HAMA) and patient health questionnaire-9 (PHQ-9) were used to assess anxiety and depression levels, and the mini nutritional assessment (MNA) was used to evaluate nutritional status. According to the MMSE scores, the elderly were divided into three groups: no cognitive impairment (MMSE ≥ 27), mild cognitive impairment (MMSE 21-26), and moderate to severe cognitive impairment (MMSE ≤ 20). The general data, lifestyle habits, and scale scores of the three groups were compared. Ordered logistic regression was used to analyze the influencing factors of sleep quality. Results There were statistically significant differences in age, gender, waist circumference, body mass index (BMI), education level, pet ownership, smoking, drinking, mahjong playing behavior, exercise habits, and scale scores among the three groups (P＜0.05). Logistic regression analysis showed that age, waist circumference, gender, drinking habits, mahjong playing behavior, and chronic comorbidities are influencing factors for the PSQI grading in the elderly (P＜0.05). The MMSE score (OR＝1.037, P＝0.001), SCD score (OR＝1.123, P＜0.001), HAMA score (OR＝1.183, P＜0.001), PHQ-9 score (OR＝1.249, P＜0.001) are positive influencing factors for PSQI grading, while the MNA score is a negative influencing factor (OR＝0.960, P＝0.037). Conclusions Advanced age, female gender, low education level, no pet ownership, no mahjong playing behavior, no exercise habits, and poor sleep quality are risk factors for cognitive impairment in the elderly. Advanced age, female gender, no mahjong playing behavior and poor nutritional status are influencing factors for poor sleep quality in the elderly, and severe comorbidities, anxiety, depression, and subjective decline in cognitive function all affect sleep quality.

This article reports 2 cases of urinary retention in Alzheimer's disease with agitation treated by acupuncture. Based on patients' clinical symptoms, the etiology and pathogenesis were determined, and acupuncture was applied to Baihui (GV20), Sishencong (EX-HN1), Shenting (GV24), and bilateral Ciliao (BL32), Zhongliao (BL33), Fengchi (GB20), Taiyang (EX-HN5), etc. to regulate the mind and promote water metabolism. The positive and negative electrodes of the SDZ-Ⅴ type electroacupuncture device were attached to ipsilateral Ciliao (BL32), Zhongliao (BL33) respectively, with continuous wave, at the frequency of 15 Hz, and the current of 3 to 10 mA, depending on patients' tolerance. The needles were retained for 20 min. The treatment was delivered once every other day, 3 interventions a week and 12 interventions as 1 course. Both patients reported the micturition desire after 1 intervention with acupuncture and the catheter was removed on the same day. The urination was ameliorated without dysuresia after 1-2 courses of treatment, and the agitated behavior was alleviated. It can be the reference for the clinical treatment of urinary retention in patients with Alzheimer's disease with agitation.
