Objective. Melasma is a highly prevalent, chronic, and pigmentary disorder. This systematic review aims to evaluate the efficacy and safety of tranexamic acid (TA) for the treatment of adults with melasma. Methods. We independently searched 3 databases from beginning to 26 April, 2018. The study included 21 eligible trials. Two writers extracted data at the same time independently. Study outcomes were calculated by standardized mean differences (SMD) with 95% confidence intervals (CIs). All statistical analyses were performed using Review Manager Version 5.3 and STATA Version 15.1. Results. The combined results showed that the use of TA was associated with reduced Melasma Area and Severity Index (MASI) and Melanin Index (MI). No significant difference in Erythema Index (EI) was observed with TA treatment. Side effects were minor, with a few cases reporting mild gastrointestinal reaction, oligomenorrhoea, hypopigmentation, urticarial rash, and skin irritation xerosis. Conclusion. The meta-analysis suggested that TA treatment appeared to be a promising therapeutic approach for melasma.

: Breast cancer is the most common neoplasm, comprising 16% of all women's cancers worldwide. Research of Copper (Cu) concentrations in various body specimens have suggested an association between Cu levels and breast cancer risks. This systematic review and meta-analysis summarize the results of published studies and examine this association. We searched the databases PubMed, Scopus, Web of Science, and Google Scholar and the reference lists of relevant publications. The Standardized Mean Differences (SMDs) between Cu levels in cancer cases and controls and corresponding Confidence Intervals (CIs), as well as I2 statistics, were calculated to examine heterogeneity. Following the specimens used in the original studies, the Cu concentrations were examined in three subgroups: serum or plasma, breast tissue, and scalp hair. We identified 1711 relevant studies published from 1984 to 2017. There was no statistically significant difference between breast cancer cases and controls for Cu levels assayed in any studied specimen; the SMD (95% CI) was -0.01 (-1.06 - 1.03; P = 0.98) for blood or serum, 0.51 (-0.70 - 1.73; P = 0.41) for breast tissue, and -0.88 (-3.42 - 1.65; P = 0.50) for hair samples. However, the heterogeneity between studies was very high (P < 0.001) in all subgroups. We did not find evidence for publication bias (P = 0.91). The results of this meta-analysis do not support an association between Cu levels and breast cancer. However, due to high heterogeneity in the results of original studies, this conclusion needs to be confirmed by well-designed prospective studies.

Due to overcrowding, personnel shortages, or problematic intravenous (IV) cannulation, acute pain management is often sub-optimal in emergency departments (EDs). The objective of this systematic review and meta-analysis was to evaluate the efficacy and safety of intranasal (IN) ketamine for adult acute pain in the emergency setting. We searched and identified studies up to 21 May 2021 via PubMed, Scopus, Web of Science, Cochrane Database, and Google Scholar. The random-effects model with 95% confidence intervals (CIs) was used to estimate mean differences (MDs) and odds ratios (ORs). The I2 statistic and Cochran’s Q test were used to determine heterogeneity. The protocol was registered in PROSPERO (CRD42020213391). Seven randomised controlled trials were included with a total of 1760 patients. There was no significant difference in pain scores comparing IN ketamine with IV analgesics or placebo at 5 (MD 0.94, p = 0.26), 15 (MD 0.15, p = 0.74), 25 (MD 0.24, p = 0.62), 30 (MD −0.05, p = 0.87), and 60 (MD −0.42, p = 0.53) minutes. There was also no significant difference in the need for rescue analgesics between IN ketamine and IV analgesics (OR 1.66, 95% CI: 0.57−4.86, p = 0.35, I2 = 70%). Only mild adverse effects were observed in patients who received IN ketamine. Our results suggest that IN ketamine is non-inferior to IV analgesics and may have a role in acute pain management among adults in the ED.

Background/Aims: The aim of this study was to assess the association between circulating cell-derived microparticles (MPs) and type 2 diabetes mellitus (T2DM). Methods: A literature search was performed systematically in PubMed and Embase to identify available case-control or cross-sectional studies that compared different types of cell-derived MPs in patients with T2DM and non-diabetic controls. Pooled standardized mean differences (SMDs) of each MP type were pooled using meta-analysis. Results: Forty-eight studies involving 2,460 patients with T2DM and 1,880 non-diabetic controls were included for systematic review and 34 of which were included for quantitative study by meta-analysis. In the overall analysis, the levels of circulating total MPs (TMPs), platelet-derived MPs (PMPs), monocyte-derived MPs (MMPs) and endothelium-derived MPs (EMPs) were significantly higher in T2DM patients than those in controls (TMPs: SMD, 0.64; 95%CI, 0.12∼1.15; P=0.02; PMPs: SMD, 1.19; 95%CI, 0.88∼1.50; P <0.00001; MMPs: SMD, 0.92; 95%CI, 0.66∼1.17; P <0.00001; EMPs: SMD, 0.73; 95%CI, 0.50∼0.96; P <0.00001). Meanwhile, no significant difference was shown in leukocyte-derived MPs (LMPs) level between diabetic and non-diabetic groups (SMD, 0.37; 95%CI, -0.15∼0.89; P=0.17). Conclusions: The counts of TMPs, PMPs, MMPs and EMPs elevated in patients with T2DM. And cell-derived MPs may play a role in the pathogenesis of T2DM.

Background and Objectives: To perform a systematic review and meta-analysis with the aim of determining the relationship between H. pylori infection and psoriasis. Methods: Pubmed, Embase, China National Knowledge Infrastructure (CNKI), and Web of Science were searched for articles published up to July, 2019. Review Manager 5.3 and Stata 12.0 were used for statistical analyses. Results: The initial database search resulted in 204 articles. Through exclusion and screening, 11 studies involving a total of 1741 participants were finally included in this meta-analysis. The odds ratio (OR) of H. pylori infection rate in the psoriasis group was significantly higher than that in the control group (OR = 1.19, 95% CI 1.15–2.52, P = 0.008). Subgroup analysis showed that no significant difference was detected between the Asia group and the Europe group. As for the methods of H. pylori detection, a statistically significant increase of H. pylori infection in the IgG ELISA test group was detected, compared with the urea breath test group. In addition, analysis based on the severity of psoriasis showed a statistically significant increase of H. pylori infection in moderate and severe psoriasis patients (OR = 2.27; 95% CI: 1.42–3.63, I2 = 27%), but not in the mild psoriasis patients (OR = 1.10; 95% CI: 0.79–1.54, I2 = 0%). Conclusion: H. pylori infection is associated with psoriasis, and psoriasis patients with H. pylori infection have higher Psoriasis Area and Severity Index (PASI) scores. The findings are of considerable significance for the clinical practices.

Lack of time is seen as a barrier to maintaining a physically active lifestyle. In this sense, interval training has been suggested as a time-efficient strategy for improving health, mainly due to its potential to increase cardiorespiratory fitness. Currently, the most discussed interval training protocols in the literature are the high-intensity interval training (HIIT) and the sprint interval training (SIT). Objective: We investigated, through a systematic review and meta-analysis, which interval training protocol, HIIT or SIT, promotes greater gain in cardiorespiratory fitness (O2max/peak). The studies were selected from the PubMed (MEDLINE), Scopus and Web of Science databases. From these searches, a screening was carried out, selecting studies that compared the effects of HIIT and SIT protocols on O2max/peak. A total of 19 studies were included in the final analysis. Due to the homogeneity between studies (I2 = 0%), fixed-effects analyses were performed. There was no significant difference in the O2max/peak gains between HIIT and SIT for the standardized mean difference (SMD = 0.150; 95% CI = −0.038 to 0.338; p = 0.119), including studies that presented both measurements in mL·kg−1·min−1 and l·min−1; and raw mean differences (RMD = 0.921 mL·kg−1·min−1; 95% CI = −0.185 to 2.028; p = 0.103) were calculated only with data presented in mL·kg−1·min−1. We conclude that the literature generates very consistent data to confirm that HIIT and SIT protocols promote similar gains in cardiorespiratory fitness. Thus, for this purpose, the choice of the protocol can be made for convenience.

Abstract Background Pioglitazone’s role in the induction of atheroma regression in diabetics was suggested by several RCT. The aim of our study was to evaluate this role through a systematic review of all RCT conducted on this subject. Methods Literature was searched for relevant studies. We included all RCT that compared pioglitazone versus other antidiabetic agents. Mean differences of either AV or CIMT, HbA1C, HDL, and LDL between the two groups were used to assess the effect of pioglitazone versus alternative therapies. Results Six RCT were included with a total of 1180 patients. Pioglitazone was significantly superior to glimepiride and gliclazide in improving IMT. No significant difference was observed in overall AV, HbA1C, and LDL. Conclusion The latter findings confirm that anti-atheroma action of pioglitazone is not achieved through its antiglycemic or antidyslipidemia effects, but probably through a DNA-mediated effect, and may lead to its repurposing for reversal of organ fibrosis.

Background and Objectives: The majority of patients included in trials of anti-platelet therapy are male. This systematic review and meta-analysis aimed to determine whether, in addition to aspirin, P2Y12 blockade is beneficial in both women and men with acute coronary syndromes. </P><P> Methods: Electronic databases were searched and nine eligible randomised controlled studies were identified that had sex-specific clinical outcomes (n=107,126 patients). Risk Ratios (RR) and 95% Confidence Intervals (CI) were calculated for a composite of cardiovascular death, myocardial infarction or stroke (MACE), and a safety endpoint of major bleeding for each sex. Indirect comparison analysis was performed to statistically compare ticagrelor against prasugrel. </P><P> Results: Compared to aspirin alone, clopidogrel reduced MACE in men (RR, 0.79; 95% CI, 0.68 to 0.92; p=0.003), but was not statistically significant in women (RR, 0.88; 95% CI, 0.75 to 1.02, p=0.08). Clopidogrel therapy significantly increased bleeding in women but not men. Compared to clopidogrel, prasugrel was beneficial in men (RR, 0.84; 95% CI, 0.73 to 0.97; p=0.02) but not statistically significant in women (RR, 0.94; 95% CI, 0.83 to 1.06; p=0.30); ticagrelor reduced MACE in both men (RR, 0.85; 95% CI, 0.77 to 0.94; p=0.001) and women (RR, 0.84; 95% CI, 0.73 to 0.97; p=0.02). Indirect comparison demonstrated no significant difference between ticagrelor and prasugrel in either sex. Compared to clopidogrel, ticagrelor and prasugrel increased bleeding risk in both women and men. </P><P> Conclusion: In summary, in comparison to monotherapy with aspirin, P2Y12 inhibitors reduce MACE in women and men. Ticagrelor was shown to be superior to clopidogrel in both sexes. Prasugrel showed a statistically significant benefit only in men; however indirect comparison did not demonstrate superiority of ticagrelor over prasugrel in women.
