Randomized Controlled Trial
Transcatheter Aortic-Valve Replacement in Low-Risk Patients at Five Years.
A previous analysis in this trial showed that among patients with severe, symptomatic aortic stenosis who were at low surgical risk, the rate of the composite end point of death, stroke, or rehospitalization at 1 year was significantly lower with transcatheter aortic-valve replacement (TAVR) than with surgical aortic-valve replacement. Longer-term outcomes are unknown. ⋯ Among low-risk patients with severe, symptomatic aortic stenosis who underwent TAVR or surgery, there was no significant between-group difference in the two primary composite outcomes. (Funded by Edwards Lifesciences; PARTNER 3 ClinicalTrials.gov number, NCT02675114.).

Severe rigid spinal scoliosis (SRSS) leads to severe restrictive ventilation dysfunction. Currently, the reports about the influence of preoperative halo-pelvic traction (HPT) combined with correction surgery on pulmonary function in patients with SRSS were relatively few. This study aims to investigate (1) the influence of preoperative HPT on lung volume and pulmonary function, (2) the further influence of the following correction surgery on lung volume and pulmonary function, and (3) the relationship among deformity correction, pulmonary function test outcomes, and computed tomography-based lung volume. ⋯ Preoperative HPT can improve preoperative pulmonary function and enhance the preoperative lung volume. There were significant correlations among the variations of MTC, pulmonary function indexes, and lung volume before HPT and after surgery in patients with SRSS.

Review Meta AnalysisFace-down positioning or posturing after macular hole surgery.
Macular holes cause severe impairment of sight. With the aim of improving the outcome of surgery for macular holes, particularly larger macular holes (those measuring over 400 μm), a variable period of face-down positioning may be advised. This review is an update of a Cochrane Review published in 2011. ⋯ We identified eight RCTs evaluating face-down positioning following surgery for macular hole. The included studies were not all directly comparable due to differences in the surgical techniques used and the durations of postoperative positioning advised. Low-certainty evidence suggests that face-down positioning may have little or no effect on macular hole closure after surgery. Face-down positioning is a low-risk intervention, with serious adverse events affecting fewer than 1 in 300 people. We suggest that any future trials focus on patients with larger macular holes, with interventions and outcome measures used in previous trials (i.e. with inner limiting membrane peeling, positioning durations of three to five days, and validated quality of life metrics) to allow future meta-analyses to determine any effect with greater precision and confidence.

Case Reports
Application of platelet-rich-plasma in the postoperative treatment of perianal abscess pseudohealing: A case report.
Perianal abscess is a common disease of the anus and intestine. Surgery is an important treatment option for perianal abscess. However, some patients have a long healing time, poor healing effect after surgery, or even pseudo-healing. Platelet-rich plasma (PRP) is rich in platelets that can release a large number of factors when activated and promote wound healing. Moreover, there are few reports on the use of PRP for wounds that are difficult to heal after perianal abscess surgery. ⋯ PRP is a novel treatment option for pseudo-healing.
