Anàlisi i diagnosi ambiental dels refugis del PNAP

Els refugis de muntanya es troben situats en zones d'interès natural, sovint protegides, com és el cas dels deu refugis del Parc Natural de l'Alt Pirineu. En els darrers anys s'ha observat una diversificació en l'ús dels refugis de muntanya, originalment construïts per donar aixopluc als excursionistes, degut a l'augment del turisme i la popularització dels esports de neu i d'aventura. Els refugis estudiats es poden agrupar en tres tipologies diferents: refugis guardats, refugis alberg i refugis associats a pistes d'esquí, cadascuna de les quals presenta una realitat i unes problemàtiques diferents. Mitjançant una metodologia pròpia, es pretén fer una anàlisi i una diagnosi ambiental de cada cas d'estudi i de les diferents tipologies a partir dels vectors que poden generar un major impacte en l'entorn immediat dels refugis: aspectes socioeconòmics, arquitectura, paisatge i impacte visual, energia elèctrica i tèrmica, aigua potable i residual i residus sòlids. La diagnosi permet identificar els aspectes de cada refugi i tipologia que requereixenLos refugios de montaña están situados en zonas de interés natural, normalmente protegidas, como es el caso de los diez refugios del Parc Natural de l'Alt Pirineu.

Prediction of cervical intraepithelial neoplasia grade 2+ (CIN2+) using HPV DNA testing after a diagnosis of atypical squamous cell of undetermined significance (ASC-US) in Catalonia, Spain

Background: A protocol for cervical cancer screening among sexually active women 25 to 65 years of age was introduced in 2006 in Catalonia, Spain to increase coverage and to recommend a 3-year-interval between screening cytology. In addition, Human Papillomavirus (HPV) was offered as a triage test for women with a diagnosis of atypical squamous cells of undetermined significance (ASC-US). HPV testing was recommended within 3 months of ASC-US diagnosis. According to protocol, HPV negative women were referred to regular screening including a cytological exam every 3 years while HPV positive women were referred to colposcopy and closer follow-up. We evaluated the implementation of the protocol and the prediction of HPV testing as a triage tool for cervical intraepithelial lesions grade two or worse (CIN2+) in women with a cytological diagnosis of ASC-US. Methods: During 2007-08 a total of 611 women from five reference laboratories in Catalonia with a novel diagnosis of ASC-US were referred for high risk HPV (hrHPV) triage using high risk Hybrid Capture version 2. Using routine record linkage data, women were followed for 3 years to evaluate hrHPV testing efficacy for predicting CIN2+ cases. Logistic regression analysis was used to estimate the odds ratio for CIN2 +. Results: Among the 611 women diagnosed with ASC-US, 493 (80.7%) had at least one follow-up visit during the study period. hrHPV was detected in 48.3% of the women at study entry (mean age 35.2 years). hrHPV positivity decreased with increasing age from 72.6% among women younger than 25 years to 31.6% in women older than 54 years (p < 0.01). At the end of the 3 years follow-up period, 37 women with a diagnosis of CIN2+ (18 CIN2, 16 CIN3, 2 cancers, and 1 with high squamous intraepithelial lesions -HSIL) were identified and all but one had a hrHPV positive test at study entry. Sensitivity to detect CIN2+ of hrHPV was 97.2% (95%confidence interval (CI) = 85.5-99.9) and specificity was 68.3% (95%CI = 63.1-73.2). The odds ratio for CIN2+ was 45.3 (95% CI: 6.2-333.0), when among ASC-US hrHPV positive women were compared to ASC-US hrHPV negative women. Conclusions: Triage of ASC-US with hrHPV testing showed a high sensitivity for the detection of CIN2+ and a high negative predictive value after 3 years of follow-up. The results of this study are in line with the current guidelines for triage of women with ASC-US in the target age range of 25-65. Non adherence to guidelines will lead to unnecessary medical interventions. Further investigation is needed to improve specificity of ASC-US triage

Trends in the epidemiology of catheter-related bloodstream infections; towards a paradigm shift, Spain, 2007 to 2019

Altres ajuts: Departament de Salut. Generalitat de Catalunya ("Pla estratègic de recerca i innovació en salut (PERIS) 2019-2021"); Ministerio de Asuntos Económicos y Transformación Digital; Red Española de Investigación en Patología Infecciosa (REIPI).Background: Catheter-related bloodstream infections (CRBSI) are frequent healthcare-associated infections and an important cause of death. Aim: To analyse changes in CRBSI epidemiology observed by the Infection Control Catalan Programme (VINCat). Methods: A cohort study including all hospital-acquired CRBSI episodes diagnosed at 55 hospitals (2007-2019) in Catalonia, Spain, was prospectively conducted. CRBSI incidence rates were adjusted per 1,000patientdays. To assess the CRBSI rate trend per year, negative binomial models were used, with the number of events as the dependent variable, and the year as the main independent variable. From each model, the annual rate of CRBSI diagnosed per 1,000patientdays and the incidence rate ratio (IRR) with its 95% confidence intervals (CI) were reported. Results: During the study, 9,290 CRBSI episodes were diagnosed (mean annual incidence rate:0.20episodes/1,000patientdays). Patients' median age was 64.1years; 36.6% (3,403/9,290) were female. In total, 73.7% (n=6,845) of CRBSI occurred in non-intensive care unit (ICU) wards, 62.7% (n=5,822) were related to central venous catheter (CVC), 24.1% (n=2,236) to peripheral venous catheters (PVC) and 13.3% (n=1,232) to peripherally-inserted central venous catheters (PICVC). Incidence rate fell over the study period (IRR:0.94;95%CI:0.93-0.96), especially in the ICU (IRR:0.88;95%CI:0.87-0.89). As a whole, while episodes of CVC CRBSI fell significantly (IRR:0.88;95%CI:0.87-0.91), peripherally-inserted catheter CRBSI (PVC and PICVC) rose, especially in medical wards (IRR PICVC:1.08;95%CI:1.05-1.11; IRR PVC: 1.03; 95% 1.00-1.05). Conclusions: Over the study, CRBSIs associated with CVC and diagnosed in ICUs decreased while episodes in conventional wards involving peripherally-inserted catheters increased. Hospitals should implement preventive measures in conventional wards
