ObjectiveTo systematically review the efficacy and safety of non-myeloablative stem cell transplantation (NST) for the treatment of multiple myeloma (MM) after first autologous stem cell transplantation. MethodsSuch databases as The Cochrane Library (Issue 5, 2013), PubMed, EMbase, CBM, CNKI, VIP and WanFang Data were electronically searched to collect studies investigated the efficacy and safety of NST and non-NST for the treatment of MM after first autologous stem cell transplantation from the date of their establishment to June 13th 2013. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of the included studies. Then meta-analysis was performed using RevMan 5.1 software. ResultsSeven studies involving 1 961 participants were included, of which 626 cases were in the NST group and 1 335 cases were in the non-NST group. The results of meta-analysis showed that no significant difference was found between both groups in the overall survival rate (HR=1.06, 95%CI 0.78 to 1.44, P=0.69) and progress-free survival rate (HR=0.92, 95%CI 0.76 to 1.11, P=0.39). However, there were significant differences in the complete remission rate (RR=1.29, 95%CI 1.13 to 1.48, P=0.000 2) and treatment-related mortality rate (RR=3.40, 95%CI 2.27 to 5.07, P < 0.000 01). ConclusionThe efficacy of NST is not superior to non-NST for patients with MM which has received first autologous stem cell transplantation. It is not sufficient to recommend NST as the first-line treatment of MM based on the currently available evidence.
Objective To understand the residents’ demands and utilization of the community health services and provide a basis for the construction of reasonable medical service system. Methods From July to September 2015, a purposive sampling questionnaire survey on general team mode service to bring benefits to the community residents was conducted in 20 provincial-level administrative regions of the country. SPSS 13.0 software was used for data analysis. Results A total of 1 300 questionnaires were distributed, and 1 273 valid questionnaires were recovered. In the 221 residents who were aware of the composition of general team, the awareness rate of general team composed of traditional Chinese medical doctors and gynaecologists/pediatricians was low (70.14%, 75.11%, respectively). The awareness rate of medical services including disease diagnosis and treatment, health consultation, health education and prescription in the 1 273 residents was 70.46%, 61.19%, 59.62% and 67.56%, respectively; the residents’ top five willing to accept medical services was prescribing medicine (77.77%), infusion (74.08%), health consultation (73.21%), health education (70.54%), and planned immunization (64.49%). The biggest change of the 433 patients with chronic diseases before and after treatment in the community was the increase in self-health management (70.67%) and the healthy lifestyle improvement (56.35%). Conclusion Community general team should be oriented by the objective needs and real demands of the residents; based on the ability of medical services supply, the adjustment of the key points of medical services should be made and the rational use of medical services should be guided for the residents.
Postoperative cognitive dysfunction (POCD) is one of the most common complications after surgery under general anesthesia and usually manifests as newly presented cognitive impairment. However, the mechanism of POCD is still unclear. In addition to neurons, glial cells including microglia, astrocytes and oligodendrocytes, represent a large cell population in the nervous system. The bi-directional communication between neurons and glia provides basis for neural circuit function. Recent studies suggest that glial dysfunctions may contribute to the occurrence and progress of POCD. In this paper, we review the relevant work on POCD, which may provide new insights into the mechanism and therapeutic strategy for POCD.
Before transcatheter aortic valve replacement (TAVR), echocardiography is the first choice for preoperative screening of suitable patients, which can be used to observe the morphology of aortic valve, determine the cause of aortic stenosis, and evaluate the severity of aortic stenosis and other cardiac structure and function. During TAVR procedure, echocardiography is mainly used for real-time monitoring of complications and immediate postoperative evaluation. After TAVR, echocardiography can be used to evaluate the shape and function of the prosthesis valve and monitor long-term complications. This article reviews the research progress of echocardiography in TAVR for guiding clinical practice.
ObjectiveTo explore and analyze the nutritional risk and dietary intake of patients with coronavirus disease 2019 (COVID-19), and provide data support for nutritional intervention.MethodsCOVID-19 inpatients were investigated in Wuhan Wuchang Hospital and the People’s Hospital of Wuhan University (East Area) from March 9th to 16th, 2020 by Nutrition Risk Screening 2002 (NRS 2002) scale and designed questionnaire. The energy and protein requirements were calculated according to the standard of 30 kcal/(kg·d) and 1.2 g/(kg·d). The nutritional risk, energy and protein intake, body weight and body mass index and their changes in the mild and severe patients were analyzed. The energy and protein intake of the two types of nutritional risk patients was analyzed.ResultsA total of 98 patients with COVID-19 completed the investigation, in whom 46 (46.94%) had nutritional risk, including 32 (39.02%) with mild type and 14 (87.50%) with severe type; and the difference was statistically significant (P<0.001). Compared with the usual condition, the body weight and body mass index of the two types of patients significantly decreased (P<0.01 or P<0.001); the energy and protein intake in mild type patients were significantly higher than those in the severe type patients (P<0.001); compared with the requirement, the protein intake in the two types of patients were significantly lower than the demand, while the energy and protein intake in the mild type patients were significantly lower than the requirement (P<0.05 or P<0.01). The proportion of energy and protein intakes in patients with nutritional risk was significantly higher than that in patients without nutritional risk (P<0.001 or P<0.01); the energy and protein intakes in patients without nutritional risk was significantly higher than that in patients with nutritional risk (P<0.001); the protein intakes in patients with nutritional risk was obviously insufficient (P<0.001); while the energy intake of the patients without nutritional risk was higher than the requirement (P<0.001).ConclusionsCOVID-19 patients has high incidence of nutritional risk which was higher in the severe patients compared with the mild patients. Higher incidence and lower intake of energy and protein are in the severe patients compared with those in the mild patients. Patients with nutritional risk has a higher proportion of energy and protein inadequate intake and lower intake compared with the patients without nutritional risk.
We reported a 65-year-old female who was admitted to our institute with "recurrent subxiphoid pain accompanied by dyspnea for more than 10 days". Electrocardiogram examination suggested acute extensive anterior ST segment elevation myocardial infarction. Preoperative transthoracic echocardiography suggested ventricular septal rupture. The patient was planned for the repair of ventricular septal rupture with cardiopulmonary bypass. The formation of left ventricular aneurysm was diagnosed by intraoperative transesophageal echocardiography (TEE). The surgeon decided to abdopt the modified incision of left ventricular approach guided by TEE, which greatly improved the prognosis of the patient. The surgery duration was 197 min, aortic cross-clamping time was 56 min, cardiopulmonary bypass time was 69 min, and the patient was safely admitted to ICU after the surgery. Extubation was performed on the first day postoperatively, and the intra-aortic balloon pump support was retreated on the second day postoperatively. Postoperative echocardiography showed that no obvious residual shunt was observed after ventricular septal repairment and ventricular aneurysm resection. The patient was discharged on the 12th day after the surgery. Additionally, the mental condition was good and daily activities were not limited within 6 months postoperatively.
As the indications for transcatheter aortic valve replacement (TAVR) expand, multi-valve lesions are becoming more common in clinical practice. Moderate to severe atrioventricular regurgitation, particularly when persistent after TAVR, significantly increases the risk of adverse events. Therefore, many studies have evaluated factors that contribute to the improvement of atrioventricular regurgitation. However, this field remains controversial due to the heterogeneity of retrospective studies and the lack of randomized controlled trials. Despite advances in atrioventricular valve intervention techniques, evidence for atrioventricular regurgitation intervention after TAVR is still scarce. The management decision for atrioventricular regurgitation in patients who underwent TAVR is complex and must take into account the severity of valve disease, anatomical characteristics, quality of life, and procedural complexity. We conducted a review of atrioventricular regurgitation in patients who have received TAVR in hope that it will help decision-making in clinical practice.
