Recently, log odds of positive lymph nodes (LODDS) was proven a better prediction of outcomes than other methods in gastric cancer, pancreatic cancer, and colon cancer. However, the validity is not yet tested in oral cavity squamous cell carcinoma (OSCC). We conducted a retrospective study to compare the predictive ability of LODDS, traditional pN classification and lymph node ratio (rN) in OSCC patients. ⋯ The LODDS-based system had the highest prediction accuracy for 3-year DSS (Harrell's c-statistic, 0.803). In our series, LODDS shows great promise as a prognostic tool for OSCC. Compared with the AJCC pN classification and the rN classification, LODDS can stratify OSCC patients and help to identify high-risk patients missed by the other systems.

Review Meta Analysis Comparative Study
Systematic Review and Meta-Analysis of Carotid Artery Stenting Versus Endarterectomy for Carotid Stenosis: A Chronological and Worldwide Study.
There are disparities among the results of meta-analyses under different circumstances of carotid artery stenting (CAS) versus endarterectomy (CEA) for carotid stenosis. This study aimed to assess the efficacies of CAS and CEA for carotid stenosis at 5-year intervals and worldwide. Comparative studies simultaneously reporting CAS and CEA for carotid stenosis with at least 10 patients in each group were identified by searching PubMed and Embase in accordance with preferred reporting items for systematic reviews and meta-analyses guidelines, and by reviewing the reference lists of retrieved articles. ⋯ This systematic review, compared with those of other meta-analyses, included all available comparative studies and analyzed them at 5-year intervals, in different continents, and under different study designs. Current evidence suggests that the efficacy of CEA is superior to CAS for freedom from stroke/death within 30 d, especially from 2006 to 2015, in North America and Europe. Meanwhile, the superiority was also observed for restenosis at 1-year, transient ischemic attack within 30 d, and stroke/death at 4- and 10-year follow-ups.

A wide array of drugs are available for the treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH), but the evidence for the comparative effectiveness is controversial. The objective of this study is to evaluate the comparative effectiveness and safety of monodrug therapies for BPH. Data sources are MEDLINE, EMBASE, and the Cochrane Library. ⋯ The incidence of total adverse events and withdraws due to adverse events were generally comparable among various agents. In conclusion, α-blockers, 5ARIs, and PDE5-Is are effective for BPH, with doxazosin and terazosin appearing to be the most effective agents. Drug therapies for BPH are generally safe and well-tolerated, with no major difference regarding the overall safety profile.

Observational Study
Causes of Thickening of Carotid Intima-Media Thickness in Patients With Alcoholic Liver Disease: A Prospective Observational Study.
Several studies have reported the relationship between alcoholic liver disease (ALD) and carotid intima-media thickness (CIMT). Few studies, however, have investigated the causes of CIMT thickening in patients with ALD. The authors explored the causes of CIMT thickening in patients with ALD. ⋯ Carotid intima-media thickness is associated with age and metabolic factors in patients with ALD. In addition, ALD might promote the premature occurrence of CIMT thickening. The thickening of carotid artery intima thickness, however, is not associated with cytokine profiles, oxidative balance, or immune responses in patients with ALD.

Comparative Study Observational Study
Differential Clinical Impact of Ascites in Cirrhosis and Idiopathic Portal Hypertension.
Cirrhosis and idiopathic portal hypertension (IPH) are 2 major diseases showing portal hypertension. However, characteristics and outcomes of IPH with ascites have not yet been determined. The aim of the study was to examine the influence of ascites on the long-term clinical course of IPH. ⋯ The overall survival rate appeared to favor IPH (100% at 1 year, 92.9% at 3 and 5 years; P = 0.2) more than cirrhosis (87.7% at 1 year, 75.2% at 3 years, and 63.6% at 5 years), but did not reach statistical significance. However, in patients with ascites at baseline, the survival rate was significantly better in IPH (100% at 1, 3, and 5 years, P = 0.04) than in cirrhosis (69.1% at 1 year, 43% at 3 years, 34.4% at 5 years). The presence of ascites at baseline correlated with worse survival rates in patients with cirrhosis as compared to those with IPH as the underlying etiology.
