Observational Study
C-reactive protein is an independent predictor for 1-year mortality in elderly patients undergoing hip fracture surgery: A retrospective analysis.
Numerous factors are associated with mortality after hip fracture surgery in elderly patients. The aim of this study was to investigate whether preoperative C-reactive protein (CRP) was an independent risk factor for 1-year mortality after hip fracture surgery in the elderly. The electronic medical records of 772 elderly patients (age ≥ 65 years) undergoing hip fracture surgery from May 2003 to November 2011 were reviewed retrospectively. ⋯ Low preoperative albumin and low body mass index predicted the 6-month and 1-year mortality. An increased preoperative CRP level, particularly >10.0 mg/dL, was associated with the 1-year mortality after hip fracture surgery in the elderly. In addition, a history of malignancy, high ASA PS score, and postoperative ICU admission were related to mortality after hip fracture.

Effects of remifentanil versus nitrous oxide on postoperative nausea, vomiting, and pain in patients receiving thyroidectomy: Propensity score matching analysis.
Remifentanil and nitrous oxide (N2O) are 2 commonly used anesthetic agents. Both these agents are known risk factors for postoperative nausea and vomiting (PONV). However, remifentanil and N2O have not been directly compared in a published study. ⋯ The numeric rating scale for nausea (0.55 ± 0.88 vs 0.27 ± 0.76, P = 0.01) was higher and complete response (88 [68.8%] vs 106 [82.8%], P = 0.001) was lower in group N2O compared with group remifentanil on postoperative day 0. However, the visual analog scale score for pain (3.47 ± 2.02 vs 3.97 ± 1.48, P = 0.025) was higher in group remifentanil than group N2O on postoperative day 0. In patients receiving IV-PCA after thyroidectomy, postoperative nausea was lower but postoperative pain was higher in group remifentanil.

From biportal to uniportal video-assisted thoracoscopic anatomical lung resection: A single-institute experience.
Our study sought to review our experience from biportal to uniportal video-assisted thoracoscopic surgery (VATS) major lung resection. Lessons we learned from the evolution regarding technical aspects were also discussed. We retrospectively reviewed patients who underwent VATS lobectomy or segmentectomies in Ditmanson Medical Foundation Chia-Yi Christian Hospital, Chia-Yi, Taiwan, during January 2012 and December 2014. ⋯ Operation time (146.1 ± 31.9-158.7 ± 40.5 minutes; P = 0.077), chest drainage time (3.8 ± 3.3-4.4 ± 2.4 days; P = 0.309), conversion to thoracotomy rate (2.2%-2.6%; P = 0.889), and complication rate (15.6%-19.7%; P = 0.564) were equal between the groups, whereas blood loss (96.7 ± 193.2-263.6 ± 367; P = 0.006) was lower in the uniportal group. For lung cancer cases, there were no statistical differences in the histology, cancer staging, mediastinal lymph node dissection stations, numbers of dissected N1, N2, and overall lymph nodes between uniportal and biportal groups. Our preliminary data showed that uniportal VATS anatomical lung resection is as feasible, equally safe, and of comparative oncological clearance efficacy to biportal VATS.

In a patient underwent aortic valve replacement (AVR) due to bicuspid aortic valve (BAV) insufficiency without marked dilation of ascending aorta, the development of delayed-typed aneurysmal complication of ascending aorta has been often reported because the dilated aorta tends to grow insidiously with age. ⋯ After successful AVR in the patient with BAV insufficiency and mildly dilated ascending aorta, a regular aortic imaging such as cardiac MDCT with aortography would be helpful to monitor the morphology and size of ascending aorta and related complications to guide future management.

Risk factors for unavoidable removal of instrumentation after surgical site infection of spine surgery: A retrospective case-control study.
Surgical site infection (SSI) after spine instrumentation is difficult to treat, and often requires removal of instrumentation. The removal of instrumentation after spine surgery is a severe complication that can lead to the deterioration of activities of daily living and poor prognosis. Although there are many reports on SSI after spine surgery, few reports have investigated the risk factors for the removal of instrumentation after spine surgery SSI. ⋯ Pseudarthrosis occurred in 2 of 4 cases (50%) after instrumentation removal. Risk factors identified for instrumentation removal after spine SSI were a greater number of past surgeries, low preoperative hemoglobin, high preoperative creatinine, high postoperative infection treatment score for the spine, and the presence of methicillin-resistant Staphylococcus aureus. In these high risk cases, attempts should be made to decrease the risk factors preoperatively, and careful postoperative monitoring should be conducted.
