Psychological interventions for coronary heart disease
A meta-analysis was conducted on 35 trials involving 10,703 individuals who had experienced a myocardial infarction and were randomised to an intervention involving some form of psychological therapy. Ten of these studies involved individuals with confirmed psychiatric diagnoses. Moderate quality evidence found no reduction of risk for total mortality or revascularisation procedures in comparison to usual care. Low quality evidence found no risk reduction for non-fatal MI although there was a 21% reduction in cardiac mortality. There was also some evidence of benefit on measures of psychological morbidity including anxiety, depression, and stress. It is concluded that psychological interventions may reduce cardiac mortality, although stronger evidence is required before this can be definitively concluded. It is also not clear who benefits most from psychological interventions

Glycated hemoglobin variability and the risk of cardiovascular events in patients with prediabetes and type 2 diabetes mellitus: A post‐hoc analysis of a prospective and multicenter study
Abstract Aims/Introduction High glycated hemoglobin (HbA1c) variability has been reported to be linked with cardiovascular events in type 2 diabetes patients. Only a few studies have been carried out on Asian patients. This study aimed to investigate the association of prediabetes and type 2 diabetes in Asian patients by performing a post‐hoc analysis of a multicenter, prospective, observational study. Materials and methods Data for prediabetes and type 2 diabetes patients were retrieved from a multicenter national registry entitled “CORE‐Thailand study.” The primary outcome was 4P‐MACE (major adverse cardiovascular events, including non‐fatal myocardial infarction, heart failure hospitalization, non‐fatal stroke and all‐cause death). Patients were stratified according to quartiles of HbA1c standard deviation. The Cox proportional hazards regression model was used to estimate the association of HbA1c variability with incident cardiovascular disease. Results A total of 3,811 patients with prediabetes and type 2 diabetes were included. The median follow‐up duration was 54 months. In the fully adjusted model, the highest quartile of HbA1c variability showed a statistically significant association with 4P‐MACE (hazard ratio [HR] 2.77, 95% confidence interval [CI] 1.77–4.35), fatal and non‐fatal myocardial infarction (HR 6.91, 95% CI 1.90–25.12), hospitalization for heart failure (HR 3.34, 95% CI 1.20–9.26) and all‐cause death (HR 3.10, 95% CI 1.72–5.57). All these outcomes were statistically significantly different among four quartiles of HbA1c (log‐rank P‐value <0.05). Fatal and non‐fatal stroke showed no statistically significant association with high HbA1c variability. Conclusion High HbA1c variability in the highest quartile showed a statistically significant association with multiple adverse cardiovascular events in an Asian population. Minimizing HbA1c fluctuation during long‐term follow up should be another important objective for type 2 diabetes patients

The Ariel Project: A prospective cohort study of maternal-child transmission of human immunodeficiency virus type 1 in the era of maternal antiretroviral therapy
In a prospective cohort study, clinical and biologic factors that contribute to maternal-child transmission of human immunodeficiency virus type 1 (HIV-1) were studied. HIV-infected pregnant women and their infants were evaluated prospectively according to a standardized protocol. Of 204 evaluable women, 81% received zidovudine during their pregnancy. The infection rate among the 209 evaluable infants was 9.1%. By univariate analysis, histologic chorioamnionitis, prolonged rupture of membranes, and a history of genital warts were significantly associated with transmission. Additional factors associated with transmission that approached significance included a higher maternal virus load at delivery and the presence of cocaine in the urine. In a logistic regression model, histologic chorioamnionitis was the only independent predictor of transmission. Despite a significantly higher transmission rate at one site, no unique viral genotype was found at any site. Thus, chorioamnionitis was found to be the major risk factor for transmission among women receiving zidovudine

Managing work flow in high enrolling trials: The development and implementation of a sampling strategy in the PREPARE trial.
IntroductionPragmatic trials in comparative effectiveness research assess the effects of different treatment, therapeutic, or healthcare options in clinical practice. They are characterized by broad eligibility criteria and large sample sizes, which can lead to an unmanageable number of participants, increasing the risk of bias and affecting the integrity of the trial. We describe the development of a sampling strategy tool and its use in the PREPARE trial to circumvent the challenge of unmanageable work flow.MethodsGiven the broad eligibility criteria and high fracture volume at participating clinical sites in the PREPARE trial, a pragmatic sampling strategy was needed. Using data from PREPARE, descriptive statistics were used to describe the use of the sampling strategy across clinical sites. A Chi-square test was performed to explore whether use of the sampling strategy was associated with a reduction in the number of missed eligible patients.Results7 of 20 clinical sites (35%) elected to adopt a sampling strategy. There were 1539 patients excluded due to the use of the sampling strategy, which represents 30% of all excluded patients and 20% of all patients screened for participation. Use of the sampling strategy was associated with lower odds of missed eligible patients (297/4545 (6.5%) versus 341/3200 (10.7%) p < 0.001).ConclusionsImplementing a sampling strategy in the PREPARE trial has helped to limit the number of missed eligible patients. This sampling strategy represents a simple, easy to use tool for managing work flow at clinical sites and maintaining the integrity of a large trial
