Abstract
Paclitaxel-induced peripheral neuropathy is a common reason for dose reduction or early cessation of therapy. Nab-paclitaxel was developed to provide additional clinical benefits and overcome the safety drawbacks of solvent-based paclitaxel. However, the incidence of peripheral neuropathy induced by nab-paclitaxel was reported higher than solvent-based paclitaxel but evidence remains inconsistent. Therefore, we conducted a meta-analysis to compare the incidence and severity of peripheral neuropathy between nab-paclitaxel and solvent-based paclitaxel mono-chemotherapy. In total, 24 articles were included in this meta-analysis. Results revealed the incidence of peripheral neuropathy induced by nab-paclitaxel was higher than solvent-based paclitaxel. The dosage and assessment method could influence the comparison of the incidence and severity of peripheral neuropathy between nab-paclitaxel and solvent-based paclitaxel. Current evidence suggests the incidence of peripheral neuropathy induced by nab-paclitaxel was higher than solvent-based paclitaxel among cancer patients received mono-chemotherapy. When received nab-paclitaxel, more attention should be paid to peripheral neuropathy.

Abstract
This study is a meta-analysis of the previous epidemiological studies which investigated the quantitative estimates of the association between independent or combined exposure to noise and mixed organic solvents and hearing loss until October 2014. Overall, 15 studies with information on 7530 individuals (6% female) were included. Having assessed - by puretone audiometry - the adjusted odds ratio estimates for the association between solvents mixture exposure and the risk of developing hearing loss stood at 2.05 (95% confidence interval (CI): 1.44-2.9). Similarly, for subjects who were concurrently exposed to noise and solvents mixture, an OR of 2.95 (95% CI: 2.1-4.17) was obtained. There was some evidence of heterogeneity within each of the 2 exposure groups (p heterogeneity < 0.001). This heterogeneity was not explained by differences in strength of effect between duration of exposure, the number of solvent and exposure index in subgroups of solvents mixture exposure. Based on the available data, our analysis has provided the evidence of increased risk of developing hearing loss for workers exposed to organic solvents even at quite low concentration. Moreover, if such exposure is accompanied by noise, it will exacerbate the extent of hearing loss. Int J Occup Med Environ Health 2017;30(4):521-535.

Abstract
OBJECTIVES Radiofrequency thermal ablation (RF) and percutaneous ethanol injection (PEI) have been employed in the treatment of small hepatocellular carcinoma (HCC) as curative treatments. The aim of the study was to review the available evidence comparing RF to PEI for small HCC. SEARCH STRATEGY Cochrane, MEDLINE, CANCERLIT, and ENBASE databases were used. SELECTION CRITERIA randomized clinical trials evaluating RF vs. PEI. Data were extracted from each randomized controlled trial (RCT). Primary outcomes were overall survival and local recurrence. Meta-analysis software was used and risk differences (RDs) and their 95% confidence intervals and Q-test for heterogeneity were calculated. RESULTS Five RCTs were identified including 701 patients. The overall survival was significantly higher in patients treated with RF than in those treated with PEI (RD 0.116, 95% CI 0.173/0.060; heterogeneity not present). Local recurrence rate is significantly higher in patients treated with PEI than in those treated with RF. In the RF group the 1, 2, and 3 years cancer-free survival rates were significantly better than in the PEI-treated patients (respectively: RD 0.098-95% CI 0.006/0.189; heterogeneity P=0.57; RD 0.187, 95% CI 0.082/0.293; heterogeneity P=0.98; RD 0.210, 95% CI 0.095/0.325; heterogeneity P = 0.78). A small number of adverse events were reported in the two treatments. CONCLUSIONS RF ablation is superior to PEI in the treatment of small HCC with respect to overall survival, 1, 2, and 3 years survival rates, 1, 2, and 3 cancer-free survival rates, and tumor response. RF shows a significantly smaller risk of local recurrence.

Abstract
BACKGROUND Contrast-induced nephropathy is the leading cause of in-hospital acute renal failure. This side effect of contrast agents leads to increased morbidity, mortality, and health costs. Ensuring adequate hydration prior to contrast exposure is highly effective at preventing this complication, although the optimal hydration strategy to prevent contrast-induced nephropathy still remains an unresolved issue. Former meta-analyses and several recent studies have shown conflicting results regarding the protective effect of sodium bicarbonate. The objective of this study was to assess the effectiveness of normal saline versus sodium bicarbonate for prevention of contrast-induced nephropathy. METHODS The study searched MEDLINE, EMBASE, Cochrane databases, International Pharmaceutical Abstracts database, ISI Web of Science (until 15 December 2008), and conference proceedings for randomized controlled trials that compared normal saline with sodium bicarbonate-based hydration regimen regarding contrast-induced nephropathy. Random-effects models were used to calculate summary odds ratios. RESULTS A total of 17 trials including 2,633 subjects were pooled. Pre-procedural hydration with sodium bicarbonate was associated with a significant decrease in the rate of contrast-induced nephropathy (odds ratios 0.52; 95% confidence interval 0.34-0.80, P = 0.003). Number needed to treat to prevent one case of contrast-induced nephropathy was 16 (95% confidence interval 10-34). No significant differences in the rates of post-procedure hemodialysis (P = 0.20) or death (P = 0.53) was observed. CONCLUSION Sodium bicarbonate-based hydration was found to be superior to normal saline in prevention of contrast-induced nephropathy in this updated meta-analysis.
