A 70-year-old female patient presented with fatigue and edema for 3 months and was found to have elevated serum creatinine for 3 weeks. During the course of the disease, she had fever and cough. Examinations revealed multiple ground-glass opacities in both lungs and positivity for myeloperoxidase-anti-neutrophil cytoplasmic antibodies (ANCA), leading to a diagnosis of ANCA-associated vasculitis. The patient′s condition initially improved after pulse glucocorticoid therapy combined with cyclophosphamide. During treatment, however, the patient developed hematochezia, and colonoscopy revealed multiple colonic ulcers. Immunohistochemistry of colonic mucosal biopsy confirmed cytomegalovirus (CMV) positivity, establishing a diagnosis of CMV colitis. The patient was found to have concurrent Clostridioidesdifficile and pulmonary infections. During the disease course, the patient also developed deep vein thrombosis and roxadustat-associated central hypothyroidism. Given the presence of multiple comorbidities, rituximab was subsequently used for vasculitis treatment, resulting in sustained remission. This case highlights the importance of highly individualized treatment strategies for older patients with vasculitis, requiring adjustment of immunosuppressive therapy intensity based on disease progression.

Objective:To establish a risk prediction model for hospital acute heart failure in elderly patients with chronic heart failure (CHF) .Methods:From January 2018 to December 2020, 619 elderly CHF patients admitted to the Cardiovascular Department of Peking University Third Hospital were selected as the research object by convenience sampling. The patients were divided into the occurrence group ( n=55) and the non-occurrence group ( n=564) according to whether the patients had acute heart failure in hospital. Binomial Logistic regression was used to explore the independent risk factors of acute heart failure in elderly CHF patients. The nomogram model was constructed by R software, and its prediction effect was verified. Results:Binomial Logistic regression showed that high heart rate at admission [ OR=1.021, 95% CI (1.003, 1.039) ], history of cerebrovascular disease [ OR=2.253, 95% CI (1.197, 4.240) ], constipation [ OR=10.382, 95% CI (1.376, 78.308) ], arrhythmia [ OR=2.051, 95% CI (1.079, 3.898) , taking aspirin [ OR=2.741, 95% CI (1.447, 5.193) ], intravenous diuretics [ OR=6.326, 95% CI (2.629, 15.220) ]and high level of N-terminal forebrain natriuretic peptide [ OR=3.511, 95% CI (1.890, 6.521) ]were independent risk factors for hospital onset of acute heart failure in elderly patients with CHF, and the use of vasodilator was a protective factor. The nomogram model was validated. The area under the receiver operating characteristic curve ( AUC) of the subject was 0.808 [95% CI (0.753, 0.864) ], the AUC of internal validation was 0.821 [95% CI (0.764, 0.871) ], and the calibration curve was a straight line with a slope close to 1. Conclusions:There are many risk factors of hospital acute heart failure in elderly CHF patients. The prediction model based on risk factors has good discrimination and calibration, and can predict the risk of acute heart failure in elderly CHF patients in hospital.

Objective:To understand the cognition and attitude of nursing managers to horizontal violence among nurses.Methods:From October to December 2018, semi-structured interviews were conducted with nursing managers in a Class ⅢGrade A hospital in Shanghai by using the purposive sampling method.Results:Five themes were extracted, namely, the low level of understanding of nurse managers on horizontal violence among nurses, effects of horizontal violence among nurses on psychology and work of nurses, the lack of enthusiasm of nursing managers in dealing with horizontal violence among nurses, nursing managers thoughthorizontalviolence was influenced by many factors and nursing managers thought that there was a lack of support for nurses suffering from horizontal violence.Conclusions:Nursing managers should enrich relevant knowledge, timely find and deal with horizontal violence in time and provide psychological support to victim nurses. Medical institutions should also formulate relevant rules and regulations to provide a basis for nursing managers when dealing with horizontal violence.
