© The Author(s) 2020.Background Cross-sectional studies show that the prevalence of comorbid depression in people with tuberculosis (TB) is high. The hypothesis that TB may lead to depression has not been well studied. Our objectives were to determine the incidence and predictors of probable depression in a prospective cohort of people with TB in primary care settings in Ethiopia. Methods We assessed 648 people with newly diagnosed TB for probable depression using Patient Health Questionnaire, nine-item (PHQ-9) at the time of starting their anti-TB medication. We defined PHQ-9 scores 10 and above as probable depression. Participants without baseline probable depression were assessed at 2 and 6 months to measure incidence of depression. Incidence rates per 1000-person months were calculated. Predictors of incident depression were identified using Poisson regression. Results Two hundred and ninety-nine (46.1%) of the participants did not have probable depression at baseline. Twenty-two (7.4%) and 26 (8.7%) developed depression at 2 and 6 months of follow up. The incidence rate of depression between baseline and 2 months was 73.6 (95% CI 42.8-104.3) and between baseline and 6 months was 24.2 (95% CI 14.9-33.5) per 1000 person-months respectively. Female sex (adjusted β = 0.22; 95% CI 0.16-0.27) was a risk factor and perceived social support (adjusted β = -0.14; 95% CI -0.24 to -0.03) was a protective factor for depression onset. Conclusion There was high incidence of probable depression in people undergoing treatment for newly diagnosed TB. The persistence and incidence of depression beyond 6 months need to be studied. TB treatment guidelines should have mental health component. © The Author(s) 2020.Background Colombia's 6.5 million internally displaced persons (IDPs) have been exposed to trauma, loss, and hardships. Common mental disorders (CMDs) are prevalent in this group, yet there are few evidence-based psychosocial interventions for this population. We assessed the feasibility and acceptability of a stepped-care intervention for women IDPs in Bogota, Colombia. Methods Feasibility to recruit participants for an intervention trial, to screen for CMDs and displacement-related traumas, to refer high-risk cases to professional consultation, to implement evidence-based interpersonal counseling (IPC) for women with diagnosed CMDs, to retain participants in the intervention, and to conduct follow-up assessments was assessed. Assessment instruments were validated. The intervention was delivered by trained outreach personnel. Intervention acceptability was assessed by monitoring session attendance, dropout rates, and satisfaction. Potential efficacy was evaluated with pre- and post-intervention measures of CMDs. Results We recruited 279 women IDPs into the intervention. On screening, 177 (63.4%) had symptom levels suggesting a CMD. Participants endorsed a wide range of displacement-related exposures. Most participants receiving IPC decreased their symptom levels at follow-up. Many participants did not complete the recommended number of IPC sessions; loss to follow-up was 30%. The performance of the outreach personnel improved after the initial intervention team was replaced with community members trained to deliver the intervention. The Bogotá health system was unable to reliably accommodate emergency psychiatric referrals. Conclusions The IPC intervention shows promise, but significant challenges remain for improving reach, adherence, and participant retention. We identified strategies and partnerships to redress some of the main study limitations. © The Author(s) 2019.in English, French Contexte De petits essais à répartition aléatoire ont montré que l’utilisation d’un dialysat à basse température réduisait le risque d’hypotension intra-dialytique. De même, certaines études observationnelles ont démontré qu’un dialysat à basse température était associé à un plus faible risque de mortalité toute cause ou d’origine cardiovasculaire. Le temps est venu de procéder à un vaste essai à répartition aléatoire comparant les effets d’un dialysat à basse température et à température standard sur les principaux résultats cardiovasculaires. Objectif Répartir aléatoirement des centres d’hémodialyse ambulatoire pour qu’ils suivent pendant quatre ans (i) un protocole personnalisé de dialysat à basse température ou (ii) un protocole de dialysat à température standard, et tester l’effet sur les hospitalisations et la mortalité attribuables à des événements cardiovasculaires. Type d’étude Un essai clinique à répartition aléatoire en grappes. Cadre Le 1er février 2017, des centres d’hémodialysanalyse primaire adoptera une approche fondée sur l’intention de traiter. Un modèle de Cox servira à estimer le rapport de risque du temps écoulé jusqu’au premier événement. La corrélation intra-centre sera prise en compte à l’aide d’un estimateur sandwich robuste. Le temps d’observation sera censuré à la date de fin de l’essai ou au moment d’un décès non lié à un événement cardiovasculaire.Introduction Stent underexpansion is a predictor of in-stent-restenosis and stent thrombosis. Semi-compliant balloons (SCBs) are generally used for lesion preparation. selleck kinase inhibitor It remains unknown whether routine predilatation using non-compliant balloons (NCBs) improves stent expansion in ordinary coronary lesions. Methods The PREdilatation by high-pressure NC balloon catheter for better vessel preparation and Optimal lesion preparation with non-compliant balloons for the implantation of bioresorbable vascular scaffolds studies randomised patients presenting with stable coronary artery disease or non-ST-elevation myocardial infarction requiring stent implantation to lesion preparation using NCBs versus SCBs. Stent expansion index (SEI-minimal luminal area/mean luminal area on optical coherence tomography) and periprocedural complications were compared. Results We enrolled 104 patients 53 patients (54 lesions) vs 51 patients (56 lesions) to the NCB and SCB groups, respectively. Predilatation pressure was higher in the NCB group (24±7 atmospheres (atm) vs 14±3 atm, p less then 0.
