Abstract
OBJECTIVE Apart from dietary restriction and medical therapy, the benefits of cardiovascular protection offered by polyunsaturated fatty acid (PUFA) supplements in patients with ESRD receiving maintenance dialysis remain unclear. This systematic review and meta-analysis examined the effects of PUFAs on blood pressure, heart rate (HR), HR variability (HRV), and cardiovascular disease (CVD) prognosis. METHODS We identified randomized controlled trials (RCTs) from Embase, PubMed (including MEDLINE), and Web of Science. We included seven RCTs that involved 724 patients with ESRD receiving dialysis and PUFA supplements. RESULTS The data indicated that compared with the control group, the PUFA group demonstrated decreased cardiovascular events (Peto odds ratio = 0.52, 95% confidence interval [CI] = 0.32 to 0.85, P = 0.009) and HRV (changes in the mean HR [mean difference = -2.59, 95% CI = -4.91 to -0.26, P = 0.03, I2 = 0%]; mean RR interval [MD = 29.03, 95% CI = 5.43 to 52.63, P = 0.02, I2 = 0%]; mean of the standard deviation of all normal RR intervals for all 5 min segments [MD = 2.73, 95% CI = 0.48 to 4.99, P = 0.02, I2 = 0%], and square root of the mean of the sum of the squares of differences between adjacent intervals [MD = 2.03, 95% CI = 0.04 to 4.03, P = 0.05, I2 = 0%]). CONCLUSION PUFA supplements appeared to improve CVD prognosis in patients receiving dialysis. Additional RCTs with longer follow-up periods need to clarify the benefits of PUFA supplements in this patient population.

[PMID: 32021110 PMCID: PMC6974131 DOI: 10.2147/dddt.s207743] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Accepted: 09/27/2019] [Indexed: 12/23/2022]
Abstract
Background/Aims To evaluate the effects of topical cyclosporin A (CsA) and artificial tears (ATs) for treating patients with dry-eye disease (DED). Methods On January 25, 2019, five electronic databases and reference lists were searched for randomized clinical trials (RCTs) comparing CsA with ATs among patients with DED. The search strategy had no restriction on language or time. Two authors extracted surgery, mean age, anesthesia for Schirmer’s test, tear-breakup time, Schirmer’s test score, fluorescein-staining score, ocular surface–disease index, and adverse events. Mean differences (MDs) were calculated for continuous outcomes and Peto ORs for dichotomous data with zero cells. Results were analyzed with 95% CIs in a random-effect model. Results Eleven RCTs recruiting 1,085 cases with DED were included. Pooled results showed that CsA had better tear-breakup time (MD 0.94, 95% CI 0.08–1.80), fluorescein-staining score (standardized MD −0.72, 95% CI −1.28 to −0.16), and ocular surface–disease index (MD −4.75, 95% CI −6.31 to −3.18) when compared to ATs. Although CsA had more adverse events than ATs (Peto OR 7.70, 95% CI 3.17–18.68), no serious adverse events were reported. Conclusion Overall, CsA is an effective option for treating patients with DED, yet our evidence indicated decreasing effects when CsA was combined with ATs. CsA may be worth suggesting to relatively older patients with DED. We anticipate further RCTs to explore the effects of treatment duration, optimal dosage, and efficacy of CsA in different DED etiology. ![]()

Abstract
Background Intracytoplasmic sperm injection (ICSI) is a popular treatment for male infertility due to obstructive azoospermia (OA). Testicular sperm aspiration (TESA) and percutaneous epididymal sperm aspiration (PESA) are two common sperm retrieval approaches for ICSI among men with OA. However, the comparative efficacies of TESA and PESA have been debated for more than a decade and there has been no synthesis of the available evidence. This meta-analysis compared fertility outcomes between TESA and PESA among men with OA undergoing ICSI. Methods We searched Embase, PubMed, ScienceDirect, and Web of Science to identify studies comparing the effectiveness of TESA and PESA for ICSI. Study quality was assessed using the Newcastle-Ottawa scale. Data were pooled using a random-effects model. Outcomes were fertilization rate, implantation rate, pregnancy rate, and miscarriage rate. Results are expressed as odds ratio (OR) with 95% confidence intervals (CIs). Study heterogeneity was evaluated by the I-square (I2) statistic. Results Of 2,965 references retrieved, eight studies met eligibility criteria. These studies included 2,020 men receiving 2,060 ICSI cycles. The pooled results showed no significant differences in pregnancy and miscarriage rates between TESA and PESA groups, but TESA yielded a significantly higher implantation rate than PESA (OR =1.58, P=0.02, I2=24%). Conclusions TESA and PESA yielded similar pregnancy and miscarriage rates for couples receiving ICSI because of OA, but each demonstrated unique advantages and disadvantages. Further studies are required to evaluate safety outcomes and efficacy for specific clinical groups.

Abstract
BACKGROUND To comprehensively evaluate the efficacy and safety of Retzius sparing (RS) for men undergoing robot-assisted laparoscopic prostatectomy (RARP). METHODS We searched four electronic databases and reference lists of relevant studies for eligible research published before March 11, 2019. After quality assessment, eligible studies were synthesized for relevant outcomes, including positive surgical margin (PSM), continence, incontinence, complication, console time, and hospital stay. RESULTS Two randomized clinical trials and four observational studies were included in this study. Quantitative syntheses revealed significantly higher PSM rates in RS-RARP compared with conventional RARP (c-RARP) (odds ratio [OR] 1.68, p = 0.02). Furthermore, we found significantly higher PSM rates at the anterior site in RS-RARP compared with c-RARP (OR 4.34, p = 0.03) and significantly lower incontinence rates in RS-RARP in the first month (OR 0.30, p < 0.001) and 12th month (OR 0.25, p < 0.001). CONCLUSIONS Our syntheses revealed higher PSM rates in the RS-RARP group, especially in the anterior aspect. However, RS-RARP had superior functional outcome of urinary continence and lower console time than did c-RARP with equivalent complication rates. Thus, we suggest that operators pay more attention to making clear surgical margins if the lesion is in anterior prostate when performing RS-RARP.

Efficacy of Polyunsaturated Fatty Acids on Inflammatory Markers in Patients Undergoing Dialysis: A Systematic Review with Network Meta-Analysis of Randomized Clinical Trials. Int J Mol Sci 2019; 20:ijms20153645. [PMID: 31349671 PMCID: PMC6695890 DOI: 10.3390/ijms20153645] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Revised: 07/07/2019] [Accepted: 07/19/2019] [Indexed: 02/06/2023] Open
Abstract
The effects of polyunsaturated fatty acids (PUFAs) on inflammatory markers among patients receiving dialysis have been discussed for a long time, but previous syntheses made controversial conclusion because of highly conceptual heterogeneity in their synthesis. Thus, to further understanding of this topic, we comprehensively gathered relevant randomized clinical trials (RCTs) before April 2019, and two authors independently extracted data of C-reactive protein (CRP), high-sensitivity C-reactive protein (hs-CRP), and interleukin-6 (IL-6) for conducting network meta-analysis. Eighteen eligible RCTs with 962 patients undergoing dialysis were included in our study. The result showed that with placebo as the reference, PUFAs was the only treatment showing significantly lower CRP (weighted mean difference (WMD): −0.37, 95% confidence interval (CI): −0.07 to −0.68), but the CRP in PUFAs group was not significantly lower than vitamin E, PUFAs plus vitamin E, or medium-chain triglyceride. Although no significant changes were noted for hs-CRP and IL-6 levels, PUFAs showed the best ranking among treatments according to surface under the cumulative ranking. Therefore, PUFAs could be a protective option for patients receiving dialysis in clinical practice.

Abstract
We aimed to evaluate the response rate of migraines by using anti-calcitonin gene-related peptide (anti-CGRP) for patients with migraines. We searched three main medical databases up to 29 March 2019. No restriction on language and publication time were applied. Eligible trials included randomized clinical trials investigating a 50%, 75%, and 100% response rate of migraine patients after anti-CGRP intervention. The collected data were dichotomous, and risk ratios (RRs) with a 95% confidence interval (CI) were used to present the quantitative synthesis results. The systematic review identified 16 eligible randomized clinical trials (RCTs) with 9439 patients. Eight of the 16 trials with 2516 patients reported a 50% response rate, and the pooled results showed a significant benefit from anti-CGRP. However, the effects seem to gradually reduce from the first month (RR 1.99, 95% CI 1.59 to 2.49) to the third month (RR 1.48, 95% CI 1.26 to 1.75) of treatment. The magnitude of effect was influenced by the type of anti-CGRP, according to the test for differences between subgroups (I-square = 53%). The funnel plots and Egger's tests did not show serious small study effects in the results. In conclusion, the current evidences confirmed that anti-CGRP treatment can reduce migraine pain in the short term (within three months), but the long-term effect should be investigated in the future. Moreover, its effects may be influenced by the type and dose of anti-CGRP. Therefore, future studies should make direct comparisons among anti-CGRP medications.
