Calidad de vida en personas con depresión y comorbilidad física desde una perspectiva de género

ObjetivoEl objetivo del estudio es describir la percepción de la calidad de vida relacionada con la salud de personas con depresión y comorbilidad física bajo una perspectiva de género. Se incluyeron 380 individuos mayores de 49 años con, al menos, una patología de las siguientes: diabetes, enfermedad obstructiva pulmonar crónica y cardiopatía isquémica, reclutadas en 31 equipos de atención primaria de Cataluña. La calidad de vida se midió con la escala EuroQol (EQ-5D). Además, se recogieron variables sociodemográficas, gravedad de depresión, índice de privación económica y ámbito de residencia. Se evaluó la relación ajustada entre el sexo y las dimensiones de calidad de vida, mediante una regresión logística multivariante.ResultadosEl 81,3% fueron mujeres; la media de edad fue de 68,4 años (DE: 8,8), La media de la escala visual analógica fue de 57,8 (DE: 17,4) en hombres y 55,8 (DE: 18,6) en mujeres. La media del EQ-Health Index fue de 0,74 (DE: 0,17) en hombres y 0,65 (DE: 0,21) en mujeres (p = 0,001). La probabilidad de presentar problemas en las dimensiones del EQ-5D mostró el sexo como factor de más peso (mujer = 1/hombre = 0) en: autocuidado OR: 2,29 (IC 95% 1,04 a 5,07) y actividades cotidianas OR: 3,09 (IC 95% 1,67 a 5,71). La movilidad se asoció con la edad OR: 1,87 (IC 95% 1,22 a 2,86), el ámbito de residencia con el dolor OR: 2,51 (IC 95% 1,18 a 5,34) y el Beck Depression Inventory (BDI) con la ansiedad/depresión OR: 4,77 (IC 95% 1,77 a 12,88).ConclusiónLa percepción en la calidad de vida de las mujeres con depresión y comorbilidad física es inferior a la de los hombres, siendo en ambos casos inferior a la de población general.Palabras clave: Calidad de vida, Depresión, Comorbilidad física, Género, Atención Primaria     

Digital thoracic drainage: a new system to monitor air leaks in pediatric population

Introduction

New digital thoracic drainage systems allow an objective measurement of air leakage. They have proven their usefulness in the postoperative thoracic surgery in adults, but there is little experience with its use in the pediatric population. The objective of our study is to analyze their safety and effectiveness in the postoperative period of the pediatric patients.

Prevalent diabetes and risk of total,colorectal, prostate and breast cancers in an ageing population: meta-analysis of individual participant data from cohorts of the CHANCES consortium

Background We investigated whether associations between prevalent diabetes and cancer risk are pertinent to older adults and whether associations differ across subgroups of age, body weight status or levels of physical activity.Methods We harmonised data from seven prospective cohort studies of older individuals in Europe and the United States participating in the CHANCES consortium. Cox proportional hazard regression was used to estimate the associations of prevalent diabetes with cancer risk (all cancers combined, and for colorectum, prostate and breast). We calculated summary risk estimates across cohorts using pooled analysis and random-effects meta-analysis.Results A total of 667,916 individuals were included with an overall median (P25–P75) age at recruitment of 62.3 (57–67) years. During a median follow-up time of 10.5 years, 114,404 total cancer cases were ascertained. Diabetes was not associated with the risk of all cancers combined (hazard ratio (HR) = 0.94; 95% confidence interval (CI): 0.86–1.04; I² = 63.3%). Diabetes was positively associated with colorectal cancer risk in men (HR = 1.17; 95% CI: 1.08–1.26; I² = 0%) and a similar HR in women (1.13; 95% CI: 0.82–1.56; I² = 46%), but with a confidence interval including the null. Diabetes was inversely associated with prostate cancer risk (HR = 0.81; 95% CI: 0.77–0.85; I² = 0%), but not with postmenopausal breast cancer (HR = 0.96; 95% CI: 0.89–1.03; I² = 0%). In exploratory subgroup analyses, diabetes was inversely associated with prostate cancer risk only in men with overweight or obesity.Conclusions Prevalent diabetes was positively associated with colorectal cancer risk and inversely associated with prostate cancer risk in older Europeans and Americans.Subject terms: Risk factors, Cancer epidemiology     

TLR2 activation in corneal stromal cells by Staphylococcus aureus‐induced keratitis

The Toll‐Like Receptor 2 (TLR2) plays an active and important role in Staphylococcus aureus‐induced chronic ocular inflammation. The aim of this study was to investigate the expression and function of TLR2 of corneal stromal cells in ex vivo rabbit model of S. aureus keratitis. Corneal buttons with sclera rims placed in an ex vivo air‐interface organ culture were assigned to two groups: corneas with epithelial and stromal abrasions. Each group was then divided into two sub‐groups exposed to UV‐killed S. aureus ATCC 6538P and S. aureus ATCC 29213, respectively. TLR2 and IL‐8 mRNA expressions were analyzed by quantitative real‐time RT‐PCR. TLR2 localization was visualized by immunofluorescence analysis. The results demonstrated that TLR2 and IL‐8 mRNA were significantly expressed in the stromal cells of the groups exposed to S. aureus strains. Moreover, it has been demonstrated that, after corneal injury, keratocytes differentiated into myofibroblasts became able to express TLR2 only when exposed to S. aureus. Identification of mechanisms regulation of corneal TLRs may lead to development of therapeutic interventions aimed at controlling corneal inflammation. This ex vivo model can be used to clarify the molecular events of bacterial‐corneal tissue interactions and their inflammatory consequences.
