Both procedures resulted in significant clinical improvements in the treatment of BPH. However, the advantages of the PAE procedure must be weighed against the potential for technical and clinical failures in a minority of patients.

Background This study investigates whether three-dimensional (3D) printing-assisted revision total hip/knee arthroplasty could improve its clinical and radiological outcomes and assess the depth and breadth of research conducted on 3D printing-assisted revision total hip and knee arthroplasty. Methods A literature search was carried out on PubMed, Web of Science, EMBASE, and the Cochrane Library. Only studies that investigated 3D printing-assisted revision total hip and knee arthroplasty were included. The author, publication year, study design, number of patients, patients’ age, the time of follow-up, surgery category, Coleman score, clinical outcomes measured, clinical outcomes conclusion, radiological outcomes measured, and radiological outcomes conclusion were extracted and analyzed. Results Ten articles were included in our review. Three articles investigated the outcome of revision total knee arthroplasty, and seven investigated the outcome of revision total hip arthroplasty. Two papers compared a 3D printing group with a control group, and the other eight reported 3D printing treatment outcomes alone. Nine articles investigated the clinical outcomes of total hip/knee arthroplasty, and eight studied the radiological outcomes of total hip/knee arthroplasty. Conclusion 3D printing is being introduced in revision total hip and knee arthroplasty. Current literature suggests satisfactory clinical and radiological outcomes could be obtained with the assistance of 3D printing. Further long-term follow-up studies are required, particularly focusing on cost-benefit analysis, resource availability, and, importantly, the durability and biomechanics of customized prostheses using 3D printing compared to traditional techniques.

Objective: This study aims to discuss clinical improvement of nursing intervention in swallowing dysfunction of elderly stroke patients. Methods: A total of 120 elderly stroke patients with swallowing dysfunction admitted in our hospital from February 2016 to September 2017 were chosen and randomly divided into control (n=60) and intervention groups (n=60). The control group was provided with conventional nursing service, and the intervention group was provided with nursing intervention. Improvements of swallowing dysfunction, living quality, pulmonary infection, and nursing satisfaction were compared between the two groups. Results: The total efficiencies in improving swallowing dysfunction are 96.67% and 83.33% for the intervention and control groups, respectively, and the difference was statistically significant (P<0.05). The scores of physical functions, psychological functions, social functions, and material life are higher in the intervention group than those in the control group (P<0.05). The pulmonary infection rate in the intervention group (1.67%) is also lower than that in the control group (11.67%, P<0.05). Nursing satisfaction was significantly different between the two groups (P<0.05). The scores of nursing satisfaction are 98.33% and 88.33% in the control and intervention groups, respectively. Conclusions: Nursing intervention exerts a significant clinical effect on improving swallowing dysfunction of elderly stroke patients. Such intervention can also improve the living quality and nursing satisfaction of the patients and reduce pulmonary infection rate. Hence, nursing intervention is worthy of clinical research and promotion.

ObjectiveTo determine the efficacy of aminocaproic acid on perioperative hidden blood loss (HBL) in elderly patients with femoral intertrochanteric fracture treated with proximal femoral nail anti-rotation (PFNA).MethodsSeventy consecutively admitted elderly patients with femoral intertrochanteric fracture treated with PFNA between 1 May 2017 and 1 May 2018 were recruited. The patients were randomised into the experimental and control groups receiving 1 g aminocaproic acid in 200 mL saline and only 200 mL normal saline intravenously, respectively. The following factors were recorded: demographic characteristics, haemoglobin and haematocrit levels on preoperative day 1 and postoperative days 1 and 3, surgical blood loss, postoperative drainage, the rate and volume of transfusion, and complications.ResultsNo significant differences were seen in surgical blood loss and postoperative drainage between the experimental and control groups, though total blood loss was greater in the control group. Visible blood loss and HBL were significantly lower in the experimental group than in the control group, and a lower rate and volume of transfusion were also recorded in the experimental group.ConclusionAminocaproic acid significantly reduced perioperative HBL and volume and rate of transfusion in elderly patients with femoral intertrochanteric fracture receiving PFNA.
