Patients with atrial fibrillation complicated with kidney disease have a high risk of stroke and bleeding, and have some limitations or contraindications to oral anticoagulants. Left atrial appendage closure has been used as an alternative to oral anticoagulation in patients with atrial fibrillation, but its efficacy and safety in patients with atrial fibrillation and chronic kidney disease need to be further confirmed. This paper intends to review the research progress of left atrial appendage occlusion in patients with atrial fibrillation complicated with chronic renal insufficiency.
Objective To analyze the clinical characteristics of dermatomyositis ( DM) and polymyositis ( PM) with pulmonary involvement. Methods A retrospective study was performed in 27 DM/PM patients with pulmonary involvement, who were admitted to the First People’s Hospital of Kunming fromJanuary2001 to December 2009. The clinical manifestation, laboratory examination, chest high resolution CT ( HRCT) , pulmonary function test, treatment efficacy and prognosis were analyzed. Results In 27 DM/PM patients with pulmonary involvement, pulmonary manifestations occurred in 23 cases, such as cough ( 44% ) , expectoration ( 30% ) , and dyspnea ( 11% ) . Erythrocyte sedimentation rate, creatine kinase, C-reactive protein, and lactic dehydrogenase were significantly increased in 63% , 67% , 56% , and 44% of patients. Anti-Jo-1 antibody was positive in eight cases ( 29% ) . The electromyogram ( EMG) revealed myogenic changes in all patients. Pulmonary interstitial changes were the predominant HRCT manifestations. Pulmonary function test revealed mainly restrictive ventilation dysfunction and decreased diffusion capacity. Most patients had a good prognosis by glucocorticoid treatment. Conclusions For patients with DM/PM, especially who present nonspecific pulmonary symptoms, chest HRCT and pulmonary function test should be recommended as early screening tools.
ObjectiveTo systematically evaluate the risk prediction models for postoperative delirium in adults with cardiac surgery. MethodsThe SinoMed, CNKI, Wanfang, VIP, PubMed, EMbase, Web of Science, and Cochrane Library databases were searched to collect studies on risk prediction models for postoperative delirium in cardiac surgery published up to January 29, 2025. Two researchers screened the literature according to inclusion and exclusion criteria, used the PROBAST bias tool to assess the quality of the literature, and conducted a meta-analysis of common predictors in the model using Stata 17.0 software. ResultsA total of 21 articles were included, establishing 45 models with 28733 patients. Age, cardiopulmonary bypass time, history of diabetes, history of cerebrovascular disease, and gender were the top five common predictors. The area under the curve (AUC) of the 45 models ranged from 0.6 to 0.926. Fourteen out of the 21 studies had good applicability, while the applicability of the remaining seven was unclear; 20 studies had a high risk of bias. Meta-analysis showed that the incidence of postoperative delirium in adults with cardiac surgery was 18.6% [95%CI (15.7%, 21.6%)], and age [OR=1.04 (1.04, 1.05), P<0.001], history of cerebrovascular disease [OR=1.76 (1.46, 2.06), P<0.001], gender [OR=1.73 (1.43, 2.03), P<0.001], minimum mental state examination score [OR=1.00 (0.82, 1.17), P<0.001], and length of ICU stay [OR=5.59 (4.29, 6.88), P<0.001] weer independent influencing factors of postoperative delirium after cardiac surgery. ConclusionThe risk prediction models for postoperative delirium after cardiac surgery have good predictive performance, but there is a high overall risk of bias. In the future, large-sample, multicenter, high-quality prospective clinical studies should be conducted to construct the optimal risk prediction model for postoperative delirium in adults with cardiac surgery, aiming to identify and prevent the occurrence of postoperative delirium as early as possible.
ObjectiveTo compare the disinfection effect of peracetic acid versus glutaraldehyde in disinfection of flexible endoscope, and provide suggestions for choosing endoscopic disinfectant.MethodsWe searched literatures in PubMed, Embase, Cochrane Central Library, China National Knowledge Infrastructure, Wanfang database and VIP database, with the retrieval time from the establishment of each database to July 2017, screening and comparing the disinfection qualification rate of peroxyacetic acid versus glutaraldehyde in immersion disinfection of flexible endoscope. The number of flexible endoscopies after disinfection was the main effect index, and a fixed effect model analysis was performed.ResultsSix comparative studies were enrolled in this Meta-analysis, with a total of 786 flexible endoscopes. The result of Meta-analysis showed that the qualification rate of disinfection of peracetic acid was higher than that of glutaraldehyde with the same disinfection time [relative risk=1.09, 95% confidence interval (1.06, 1.13), P<0.000 01].ConclusionThe disinfection effect of peroxyacetic acid immersion method is better than that of glutaraldehyde.
Objective To explore association of apolipoprotein B (ApoB) gene rs676210 and rs2854725polymorphisms with gallstone disease and differences of polymorphisms between Uygur population and Han population. Methods A case control study was used. One hundred and eighty-nine patients with gallstone disease from 2010 to 2014 in our hospital were collected, of which 99 cases of Uygur population and 90 cases of Han population. One hundred and ninety age- and sex-matched healthy volunteer accepted physical examination in our hospital over the same period were collected as control, of which 93 Uygur population and 97 Han population. The ApoB genotyping of DNA samples were amplified by using SNaPshot single nucleotide polymorphism (SNP). The differences of polymorphisms between Uygur population and Han population and between patients with gallstone disease and healthy volunteer were analyzed. Results ① The differences of ApoB gene rs676210 and rs2854725 allele frequencies were not found between the patients with gallstone disease and healthy volunteer whether Uygur population or Han population (Uygur population: rs676210:χ2=0.229,P=0.633; rs2854725:χ2=0.028,P=0.866. Han population: rs676210:χ2=0.608,P=0.435; rs2854725:χ2=2.673,P=0.102). ② The differences of ApoB gene rs676210 and rs2854725 allele frequencies were not found between Uygur population and Han population whether the patients with gallstone disease or healthy volunteer (Patients with gallstone disease: rs676210:χ2=0.103,P=0.748; rs2854725:χ2=3.139,P=0.076. Healthy volunteer: rs676210:χ2=0.000,P=0.990; rs2854725:χ2=2.673,P=0.102). ③ The differences of ApoB gene rs676210 and rs2854725 genotype frequencies were not found between the patients with gallstone disease and healthy volunteer whether Uygur population or Han population (Uygur population: rs676210:χ2=2.301,P=0.317; rs2854725:χ2=3.040,P=0.219. Han population: rs676210:χ2=4.909,P=0.086; rs2854725:χ2=0.107,P=0.744). ④ The differences of ApoB gene rs676210 and rs2854725 genotype frequencies were not found between Uygur population and Han population patients with gallstone disease (rs676210:χ2=0.235,P=0.899; rs2854725:χ2=3.630,P=0.057). The difference of ApoB gene rs676210 genotype frequency was not found between Uygur population and Han population with healthy volunteer (χ2=1.026,P=0.599). While the difference of ApoB gene rs2854725 genotype frequency was found between Han population and Uygur population with healthy volunteer (χ2=9.153,P=0.010). When it was compared in pairs,α=0.05/3=0.016, the difference of G/T and T/T frequencies was found between Uygur population and Han population (χ2=6.128,P=0.013), G/T of Han population (27.8%) was higher than that of Uygur population (12.9%). Conclusions ApoB gene rs676210 and rs2854725 polymorphisms are not associated with gallstone disease. For healthy volunteer, ApoB gene rs676210 polymorphism shows no ethnics-specific difference between Uygur population and Han population, but ApoB gene rs2854725 polymorphism mightbe show a difference between Uygur population and Han population. Larger sample sizes and multicenter study are needed to confirm it.
