Prevention of congenital chagas disease by trypanocide treatment in women of reproductive age: A meta-analysis of observational studies.

BACKGROUND: Maternal-foetal transmission of Chagas disease (CD) affects newborns worldwide. Although Benznidazole and Nifurtimox therapies are the standard treatments, their use during pregnancy is contra-indicated. The effectiveness of trypanocidal medications in preventing congenital Chagas Disease (cCD) in the offsprings of women diagnosed with CD was highly suggested by other studies. METHODS: We performed a systematic review and meta-analysis of studies evaluating the effectiveness of treatment for CD in women of childbearing age and reporting frequencies of cCD in their children. PubMed, Scopus, Web of Science, Cochrane Library, and LILACS databases were systematically searched. Statistical analysis was performed using Rstudio 4.2 using DerSimonian and Laird random-effects models. Heterogeneity was examined with the Cochran Q test and I2 statistics. A p-value of <0.05 was considered statistically significant. RESULTS: Six studies were included, comprising 744 children, of whom 286 (38.4%) were born from women previously treated with Benznidazole or Nifurtimox, trypanocidal agents. The primary outcome of the proportion of children who were seropositive for cCD, confirmed by serology, was signigicantly lower among women who were previously treated with no congenital transmission registered (OR 0.05; 95% Cl 0.01-0.27; p = 0.000432; I2 = 0%). In women previously treated with trypanocidal drugs, the pooled prevalence of cCD was 0.0% (95% Cl 0-0.91%; I2 = 0%), our meta-analysis confirms the excellent effectiveness of this treatment. The prevalence of adverse events in women previously treated with antitrypanocidal therapies was 14.01% (95% CI 1.87-26.14%; I2 = 80%), Benznidazole had a higher incidence of side effects than Nifurtimox (76% vs 24%). CONCLUSION: The use of trypanocidal therapy in women at reproductive age with CD is an effective strategy for the prevention of cCD, with a complete elimination of congenital transmission of Trypanosoma cruzi in treated vs untreated infected women.

The Use of Honey for Cicatrization and Pain Control of Obstetric Wounds: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: Several studies point to antibacterial properties and beneficial effects of honey on scar tissue formation, which is a low-cost and easy-to-use option. This study aimed to compare honey versus a placebo for cicatrization and pain control of obstetric wounds, and determine if one is superior to the other, in terms of efficacy, through a meta-analysis. METHODS: We searched PubMed, Scopus, Cochrane Central Register of Controlled Trials, and Web of Science. Two independent investigators identified randomized controlled trials (RCTs) comparing honey and a placebo for obstetric wounds. The primary outcomes were wound healing and pain control. RESULTS: Five randomized controlled trials and 353 patients were included, of whom, 177 (50.1%) were treated with honey. Differences were not found in the final wound healing between the honey and placebo groups (MD -0.34; 95% CI -1.13, 0.44; p = 0.39); however, there was a decrease in pain levels in the middle of the treatment (SMD -0.54; 95% CI 0.83 to 0.25, p = 0.03), reduction in the use of pain medication (ORR 0.26; 95% CI 0.08, 0.86; p = 0.03), increase in personal satisfaction in women who underwent the intervention (ORR 0.81; 95% CI 0.65, 0.98), and reduction in complications. CONCLUSION: According to the study results, honey treatments showed greater efficiency and provided benefits to the patients by accelerating wound healing and decreasing reported pain.

Peripheral arterial disease progression and ankle brachial index: a cohort study with newly diagnosed patients with type 2 diabetes.

BACKGROUND: Little is known about the evolution of peripheral arterial disease (PAD) since diagnosis and its association with glycemic and lipid control in patients with Type 2 Diabetes Mellitus (T2DM). OBJECTIVE: Evaluate the actual criteria to start screening PAD with ankle-brachial index (ABI) in T2DM patients and assess its progression and relationship with glycemic and lipid control since diagnosis. METHODS: We performed a 3-year prospective cohort study with two groups: group 1 (978 individuals with T2DM undergoing drug treatment) and group 2 [221 newly diagnosed drug-naive (< 3 months) patients with T2DM]. PAD diagnosis was by ABI ≤ 0.90, regardless any symptoms. RESULTS: As expected, abnormal ABI prevalence was higher in group 1 vs. Group 2 (87% vs. 60%, p < 0.001). However, abnormal ABI prevalence did not differ between patients over and under 50 years in both groups. Our drug-naive group stabilizes ABI (0.9 ± 0.1 vs 0.9 ± 0.1, p = NS) and improved glycemic and lipid control during follow-up [glycated hemoglobin (HbA1c) = 8.9 ± 2.1 vs 8.4 ± 2.3%, p < 0.05; LDL = 132 ± 45 vs 113 ± 38 mg/dL, p < 0.01, respectively]. When compared, patients who evolved with normalization or maintained normal ABI levels at the end [Group A, N = 60 (42%)] with those who decreased ABI to abnormal levels (ABI basal 1.0 ± 0.1 vs final 0.85 ± 0.1, p < 0.001) [Group B, N = 26 (18%)], an improvement in HbA1c (9 ± 2 vs 8 ± 2%, p < 0.05) and a correlation between the final HbA1c with ABI (r = - 0.3, p = 0.01) was found only in the first. In addition, a correlation was found between albuminuria variation and ABI solely in group A (r = - 0.3; p < 0.05). CONCLUSION: Our study suggests that ABI should be measured at diagnosis in T2DM patients, indicating that current criteria to select patients to screen PAD with ABI must be simplified. An improvement in albuminuria and glycemic and lipid control could be related with ABI normalization in newly diagnosed T2DM drug-naive patients.

Health-related quality of life in T1DM patients after high-dose cholecalciferol supplementation: data from a pilot clinical trial.

BACKGROUND: Type 1 Diabetes Mellitus (T1DM) impacts health-related quality of life (HRQoL). Cross-sectional studies suggest that low levels of vitamin D (VD) may impair HRQoL, however, the effect of VD supplementation on quality of life in T1DM patients has not yet been clarified. Our study evaluated the effects of high-dose VD supplementation on HRQoL in T1DM. METHODS: We performed a prospective study with 64 patients receiving cholecalciferol (4000 IU/day for patients with 25-OH-vitamin D [25(OH)D] between 30 and 60 ng/mL, and 10,000 IU/day for those with 25(OH)D below 30 ng/mL) for 12 weeks, as part of a research protocol. HRQoL was assessed with EuroQol instruments (EQ-5D and EQ-VAS). RESULTS: There was an improvement in global EQ-5D index, and analysing specifically the EQ-5D domains, we observed an improvement in mobility (1.3 ± 0.6 versus 1.1 ± 0.3, p < 0.01). Evaluating possible outcome influencing variables, we detected a reduction in albuminuria at the end of the trial, without changes in BMI, lipids, blood pressure, glycemic control and insulin doses. We found correlations between final albuminuria and the dimensions: mobility (r = 0.6; p < 0.01), personal care (r = 0.7; p < 0.01), pain and discomfort (r = 0.6; p < 0.01) and habitual activities (r = 0.6; p < 0.01), suggesting an association between albuminuria reduction and the impact of VD supplementation on HRQoL. CONCLUSION: Our data showed that high doses of cholecalciferol supplementation can improve HRQoL in patients with T1DM, and the reduction of albuminuria seems to be an important factor in this context.
