Objective: To evaluate the impact of the duration of breastfeeding on the intelligence of children. Materials and Methods: Eight electronic databases were searched to identify studies that investigated the impact of breastfeeding on the intelligence of children. Data were pooled, and the ratio of means (RoM) and the corresponding 95% confidence interval (95% CI) were calculated using a pairwise meta-analysis and network meta-analysis. Risk of bias was assessed using a tool developed by the CLARITY group. Data were analyzed using R version 3.5.1. Results: A total of 16 studies with 9,162 subjects were included in the review. Half of the studies were at low risk of bias. A meta-analysis indicated that breastfed children had a score 1.04-fold higher in intelligence tests compared with those that had never been breastfed (RoM: 1.04, 95% CI: 1.02-1.06, p 6 months had a score 1.06-fold higher (RoM: 1.06, 95% CI: 1.05-1.08, p 6 months demonstrated a slightly higher score than breastfeeding for 6 months showing a slight but significantly higher intelligence score than for <= 6 months.

Postoperative nausea and vomiting (PONV) is one of the most common and unpleasant postoperative complications in children. This study aims to evaluate the efficacy and safety of using dexamethasone alone or combined other drugs on the incidence of PONV in children. A systematic search of the literature was conducted from inception until March, 2019. Literature selection and data extraction were conducted by two independent reviewers. Statistical analysis was performed using the software package Review Manager Version 5.3.3. Twenty studies with total 2505 participants were included. The pooled analysis used a random-effect model showed that dexamethasone had significantly greater efficacy in incidence of POV and PON in postoperative 24 h than control. Subgroup analysis indicated the RR of dexamethasone >= 0.5 mg/kg group was the lowest compared subgroup dexamethasone <= 0.3 mg/kg and 0.3-0.5 mg/kg. There was no difference for early POV between dexamethasone and placebo groups. Dexamethasone combined with others also could significantly reduce the incidence of POV in postoperative 24 h. Few adverse effects were reported. This study indicates that dexamethasone is effective for preventing incidence of PONV in children. And multimodal approaches have shown more effectively to prevent the incidence of POV. (C) 2020 Asian Surgical Association and Taiwan Robotic Surgery Association.

Extracorporeal shock wave therapy (ESWT) as a new adjuvant therapy has shown a potential capability to promote diabetic foot ulcer (DFU) healing. The purpose of this study was to assess the efficacy and safety of ESWT on the healing of DFUs. The Cochrane Library, PubMed, Embase, Web of Science, China Biology Medicine and reference lists were searched for studies published up to December 2018. Randomized controlled trials of any design, including ESWT for patients with DFU, were included. Two reviewers extracted data, including the wound surface area (WSA), percentage of re-epithelialization, population of complete cure and unchanged and other related outcomes. Eight randomized controlled trials (N=339) were included. ESWT was found to be associated with a greater reduction of WSA by 1.54 cm2, and increase of re-epithelialization by 26.31%. A greater population with complete cure was found at the end of treatment (risk ratio [RR] = 2.22; 95% confidence interval [CI], 1.46 to 3.40); however, there was no statistically significant difference at the end of follow up (p=0.052). It can also reduce treatment inefficiency by 4.8-fold (95% CI, 0.12 to 0.37). In addition, ESWT also showed a higher superiority than hyperbaric oxygen therapy in the population for complete cure and unchanged ulcer (RR=1.83; 95% CI, 1.14 to 2.94 and RR=0.25; 95% CI, 0.13 to 0.48, respectively). ESWT is a feasible adjuvant treatment for DFUs. It can effectively improve the complete cure rate, shorten the healing period of DFUs and significantly reduce treatment ineffectiveness. This can provide new therapeutic ideas for clinical practice of intractable and recurrent DFUs.

Background: Chronic renal failure (CRF) is a serious disease that has become a burden on global and local economics and public health. In addition, non-thyroidal illness syndrome (NTIS) has become increasingly more prevalent in CRF patients. Materials and methods: A data search was conducted on the PubMed/Medline, Cochrane Library, Web of Science, Embase, and CBM databases to identify studies up to November 1st, 2018, that compared low T3 and normal T3 levels in patients with CRF. Data analysis was done by calculating the relative risks (RR) and 95% confidence intervals (95% CI) and continuous variables were described by weighted mean difference (WMD) and 95% CI. The efficacy outcomes included renal function and mortality. The Newcastle-Ottawa Scale and Agency for Healthcare Research and Quality scale were used to assess the quality of the cohort and cross-sectional studies, respectively. A funnel plot was used to identify publication bias. Results: Seventeen studies with a total of 4593 patients were finally included in the analysis. Among the 17 studies, 11 reported the mortality of CRF patients with low T3 and normal T3 levels. Subgroups were assigned according to different follow-up times and different methods of treatment. The mortality rate in the low T3 group was much higher than in the normal T3 group. 11 studies reported creatinine (Cr) results in patients with low T3 and normal T3 levels and our analysis found no significant differences between the two groups (95%CI: 0.46-0.25; P-heterogeneity = 0.000; P = 0.559). Five studies reported uric acid results and we found no significant differences between the two groups (95%CI: 0.08-0.22; P-heterogeneity = 0.438; P = 0.377). Five studies reported the urea levels in the two groups and our analysis found no significant differences (95%CI: 1.60-1.23; I2 = 0.0%; P-heterogeneity = 0.498;P = 0.798). Conclusion: Low T3 had a greater impact on the short-term prognosis of patients with CRF than on the long-term prognosis. NTIS did not cause substantial kidney damage.

Objectives: To summarize the evidence from systematic reviews (SRs) and meta-analyses that evaluated the efficacy of ginger in treating any conditions and critically assess the quality of these evidence. Methods: A systematic search of the literature was conducted from inception until February 28, 2019 using the PubMed, EMBASE, Web of science, Cochrane library, and four Chinese databases. Literature selection and data extraction were conducted by two independent reviewers. The quality of SRs was evaluated using the AMSTAR-2 tool. The GRADE system was used to assess the quality of evidence. Results: Twenty-seven SRs were included. The number of included studies were various, range from 3 to 27. The condition with the most included SRs was nausea and vomiting (n = 12, 44.4%). Many SRs showed a promising efficacy of ginger, including nausea and vomiting, metabolic syndrome and pain, while the effect of ginger for platelet aggregation failed to draw a certain conclusion. The quality of SRs was heterogeneous. All of included SRs well complied with the Item 1 ("research questions included the components of PICO") and Item 3 ("explained selection of the study designs for inclusion"). Twenty review failed to provide registration information. Only one SR reported the sources of funding for studies included. Conclusions: In our overview, most of SRs suggest ginger is a promising herbal medicine for health care, which is beneficial for nausea and vomiting, metabolic syndrome and pain. However, considering the limited quality of included evidence and heterogeneity of different clinical trials, more well-design studies are required to confirm the conclusion further.

The study aims to evaluate the effectiveness of different durations of aerobic exercise on hypertensive patients. Four electronic databases (PubMed, Embase, Cochrane Library, and Web of Science) were searched from their inception until July 2018. English publications and randomized controlled trials involving aerobic exercise treatment for hypertensive population were included. Two reviewers independently extracted the data. The Cochrane's Risk of Bias tool was used to assess the quality of included studies. In this systematic review, a total of 14 articles were included, involving 860 participants. The quality of the included studies ranged from moderate to high. The results of the meta-analysis showed that compared with the control group, significant effects of aerobic exercise were observed on reducing systolic blood pressure (SBP) (mean difference [MD] = -12.26 mm Hg, 95% confidence interval [CI] = -15.17 to -9.34, P < 0.05), diastolic blood pressure (DBP; MD = -6.12 mm Hg, 95% CI = -7.76 to -4.48, P < 0.05), and heart rate (MD = -4.96 bpm, 95% CI = -6.46 to -3.43, P < 0.05). In addition, significant reductions were observed in ambulatory DBP (MD = -4.90 mm Hg, 95% CI = -8.55 to -1.25, P < 0.05) and ambulatory SBP (MD = -8.77mm Hg, 95% CI = -13.97 to -3.57, P < 0.05). Therefore, aerobic exercise might be an effective treatment for blood pressure improvement in hypertensive patients. However, the effectiveness between the duration of different treatment needs to be well-designed and rigorous studies will be required to verify the dataset.
