Randomized Controlled Trial Observational Study
Intraoperative Dexmedetomidine Promotes Postoperative Analgesia and Recovery in Patients after Abdominal Colectomy: A CONSORT-Prospective, Randomized, Controlled Clinical Trial.
Surgery-induced acute postoperative pain and stress response may lead to prolonged convalescence. The present study was designed to investigate the effects of intraoperative dexmedetomidine on postoperative analgesia and recovery after abdominal colectomy surgeries. Sixty-seven patients scheduled for abdominal colectomy under general anesthesia were divided into two groups, which were maintained using propofol/remifentanil/dexmedetomidine (PRD) or propofol/remifentanil/saline (PRS). ⋯ During the first 24 hours after surgery, PRD patients consumed less morphine in patient-controlled analgesia, and had a lower score in visual analog scale, than their controls from the PRS group. The global 40-item quality of recovery questionnaire and 9-question fatigue severity score both showed a higher recovery score from day 3 after surgery in the PRD group. Intraoperative administration of dexmedetomidine seems to promote the analgesic property of morphine-based patient-controlled analgesia, and speed recovery from surgery in patients after abdominal colectomy.

Inhaled Corticosteroids Increase the Risk of Pneumonia in Patients With Chronic Obstructive Pulmonary Disease: A Nationwide Cohort Study.
The association of inhaled corticosteroids (ICS) and pneumonia in patients with chronic obstructive pulmonary disease (COPD) is still controversial. From the National Health Insurance Database of Taiwan, COPD cases with history of acute exacerbation (AE) were identified (COPD cohort). Time-dependent Cox regression analysis was applied to investigate the risk factors for pneumonia with COPD severity controlled by surrogate variables. ⋯ In the ICS cohort, while AE rate gradually decreased, the incidence rate of pneumonia significantly increased after ICS use (from 0.10 to 0.21 event/person-year, P = 0.001). This study demonstrates the association between ICS use and pneumonia in patients with COPD and history of AE. ICS should be judiciously used in indicated COPD patients.

Randomized Controlled Trial Multicenter Study Observational Study
Dynamic of Mixed HCV Infection in Plasma and PBMC of HIV/HCV Patients Under Treatment With Peg-IFN/Ribavirin.
The extent of mixed hepatitis C virus (HCV) genotype in different compartments (plasma and peripheral blood mononuclear cell, PBMC) and possible association with treatment efficacy in HIV/HCV coinfected patients remains to be unknown. The objective of this study was to elucidate the frequency of mixed genotype infection (MG), its profile in different compartments during anti-HCV treatment, and the possible influence of different genotypes on the response rate. The compartmentalization of HCV population was investigated by next-generation sequencing in 19 HIV/HCV coinfected patients under anti-HCV treatment with peginterferon/ribavirin (P-R). ⋯ By multivariate analysis, MG in plasma samples was the most important viral factor affecting the treatment response (P = 0.0237). Detection of MG in plasma of HIV/HCV coinfected patients seems to represent the major determinant of response to P-R treatment. This finding may have important clinical implication in light of the new therapeutic approach in HIV/HCV coinfected individuals suggesting that combination treatment with direct acting antivirals could be less effective in MG.

Comparative Effectiveness of Angiotensin-Converting Enzyme Inhibitors and Angiotensin II Receptor Blockers in Terms of Major Cardiovascular Disease Outcomes in Elderly Patients: A Nationwide Population-Based Cohort Study.
Renin and aldosterone activity levels are low in elderly patients, raising concerns about the benefits and risks of angiotensin-converting-enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARB) use. However, data from direct comparisons of the effects of ACEIs on ARBs in the elderly population remain inconclusive. In this nationwide study, all patients aged ≥ 70 years were retrieved from the Taiwan National Health Insurance database for the period 2000 to 2009 and were followed up until the end of 2010. ⋯ AT analysis produced similar results to those of ITT analysis. We were unable to demonstrate a survival difference between cohorts (HR 1.03, 95% CI 0.88-1.21) after considering drug discontinuation as a competing risk in AT analysis. Our study supports the notion that ACEI and ARB users have similar risks of major adverse cardiovascular events (MACE), even in elderly populations.

Pure Laparoscopic Versus Open Liver Resection for Primary Liver Carcinoma in Elderly Patients: A Single-Center, Case-Matched Study.
Pure laparoscopic liver resection (PLLR) has been reported to be as safe and effective as open liver resection (OLR) for liver lesions, and it is associated with less intraoperative blood loss, shorter hospital stay, and lower complication rate. However, studies comparing PLLR with OLR in elderly patients were limited. The aim of this study was to analyze the short-term outcome of PLLR versus OLR for primary liver carcinoma (PLC) in elderly patients. ⋯ The postoperative complication rates were similar between groups (Group PLLR 10.0% vs Group OLR 16.7%; P = 0.532). There was no hospital mortality in both groups. PLLR for PLC is as safe and feasible as OLR, but with less blood loss, shorter hospital stay, and lower hospitalization cost for selected elderly patients.
