Meta Analysis
Effect of Probiotics on Blood Lipid Concentrations: A Meta-Analysis of Randomized Controlled Trials.
Previous clinical studies have reported mixed results regarding the effect of probiotics on lipid metabolism. Therefore, we conducted a meta-analysis of randomized controlled trials to quantify the direction and magnitude of the potential effect of probiotics on blood lipid concentrations. Eligible studies were randomized, placebo-controlled trials whose interventions were probiotic products containing live bacteria. ⋯ In addition, industry sponsorship may affect study findings. These results suggest that the use of probiotics may improve lipid metabolism by decreasing total and LDL cholesterol concentrations. However, both the efficacy of probiotics for cholesterol lowering and safety should be investigated further in well-designed clinical trials.

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.

Comparative Study
Short-Term Prognosis of Mechanically Ventilated Patients With Guillain-Barré Syndrome Is Worsened by Corticosteroids as an Add-On Therapy.
Intravenous immunoglobulin (IVIg) has been proven most effective in treating Guillain-Barré syndrome (GBS). Corticosteroids as an add-on therapy have been prescribed in severe GBS cases. However, the efficacy of intravenous corticosteroids combined with IVIg in dealing with severe GBS remains unclear. ⋯ In addition, supportive treatment was sufficient for patients who were able to walk with help (HFGS = 3) and mildly affected (HFGS < 3) when compared with IVIg and intravenous corticosteroids. IVIg is sufficient to GBS patients who are unable to walk (HFGS > 3), while corticosteroids are detrimental for short-term prognosis in mechanically ventilated patients when used in combination with IVIg. Further prospective and randomized studies are warranted to validate this finding.

Randomized Controlled Trial
Double-Blind Randomized Trial of Pirfenidone in Chinese Idiopathic Pulmonary Fibrosis Patients.
Idiopathic pulmonary fibrosis (IPF) lacks effective treatment. Pirfenidone has been used to treat IPF patients. N-acetylcysteine (NAC) exerts antioxidant and antifibrotic effects on IPF cases. ⋯ In the pirfenidone group, the adverse event (AE) rate (52.63%) was higher than that in the control group (26.3%, P = 0.03). Rash was more common in the pirfenidone group (39.5% vs 13.2%, P = 0.02). Compared with placebo combined with high-dose NAC, pirfenidone combined with high-dose NAC prolonged the progression-free survival of Chinese IPF patients with mild to moderate impairment of pulmonary function.

Observational Study
Association Between the Neutrophil/Lymphocyte Ratio and Acute Kidney Injury After Cardiovascular Surgery: A Retrospective Observational Study.
A high neutrophil-lymphocyte ratio (N/L ratio) was associated with the development of acute kidney injury (AKI) in patients with severe sepsis. We sought to investigate the association between the perioperative N/L ratios and postoperative AKI in patients undergoing high-risk cardiovascular surgery. A retrospective medical chart review was performed of 590 patients who underwent cardiovascular surgeries, including coronary artery bypass, valve replacement, patch closure for atrial or ventricular septal defect and surgery on the thoracic aorta with cardiopulmonary bypass (CPB). ⋯ The quartiles of immediately postoperative N/L ratio were associated with graded increase in risk of AKI development (fourth quartile [N/L ratio≥10] multivariate odds ratio 5.90, 95% confidence interval [CI] 2.74-12.73; P < 0.001), a longer hospital stay, and a higher in-hospital and 1-year mortality rate (fourth quartile [N/L ratio≥10] adjusted hazard ratio for 1-year mortality [8.40, 95% CI 2.50-28.17]; P < 0.001). In patients undergoing cardiovascular surgery with CPB, elevated N/L ratios in the immediately postoperative period and on POD one were associated with an increased risk of postoperative AKI and 1-year mortality. The N/L ratio, which is easily calculable from routine work-up, can therefore assist with risk stratification of AKI and mortality in high-risk surgical patients.
