Bewonersparticipatie in het openbaar groenbeheer : 'State of the art' na vijf jaar zelfbeheer in de wijk EVA-Lanxmeer (Culemborg)

De wijk EVA-Lanxmeer (1997) is een duurzame woon- en werkwijk in Culemborg, op een grondwaterwingebied van Vitens. Het is een voorbeeldproject op het gebied van duurzame stedenbouw en participatief beleid. Het wordt door gemeenten en groepen burgers in binnen- en buitenland gebruikt om inspiratie, kennis en ervaring op te doen en uit te wisselen op het gebied van innovatief denken binnen de eigen gemeentelijke organisatie. Bewoners onderhouden zelf een belangrijk deel van het wijkgroen op een ecologische wijze. Zij doen dat in samenwerking en overleg met de gemeente Culemborg en Waterwinbedrijf Vitens. De meeste bewoners hebben sterk het gevoel dat het zelfbeheer de kwaliteit en diversiteit van het groen in de wijk verhoogt. De gezamenlijke werkzaamheden maken ongedwongen ontmoetingen met andere bewoners in de wijk mogelijk

EVALUACIÓN DE RESULTADOS QUIRÚRGICOS DESDE LA PERSPECTIVA DEL PACIENTE

RESUMENMedir la calidad de vida relacionada a salud y los síntomas de los pacientes es un problema difícil. Las medición de los problemas de salud mediante escalas o cuestionarios se ha desarrollado para crear los Instrumentos de Evaluación desde la Perspectiva del Paciente o PRO's por su nombre en inglés: Patient-reported outcomes. Los PROs evalúan la calidad de vida en forma genérica o específica en un continuo, entregando instrumentos que pueden evaluar la gravedad de una enfermedad o el impacto de una intervención desde la perspectiva del paciente en frecuentes escenarios clínicos. El objetivo de la presente revisión es entregar a clínicos e investigadores una introducción hacia los PROs y resumir sus principales propiedades.SUMMARYQuantifying health-related quality of life and specific patient symptoms it is a difficult problem. Health measurement scales has developed to include rigorous techniques to develop patient-reported outcome measures (PROs). PROs assess objectively the QoL in a continuum, providing instruments to measure the severity of a given disease or the impact of a therapeutic intervention from patient perspective in different clinical problems. The following review aims to introduce the PROs to clinicians and researchers and summarize its main properties

Acute respiratory failure in immunocompromised patients : outcome and clinical features according to neutropenia status

Abstract Background The impact of neutropenia in critically ill immunocompromised patients admitted in a context of acute respiratory failure (ARF) remains uncertain. The primary objective was to assess the prognostic impact of neutropenia on outcomes of these patients. Secondary objective was to assess etiology of ARF according to neutropenia. Methods We performed a post hoc analysis of a prospective multicenter multinational study from 23 ICUs belonging to the Nine-I network. Between November 2015 and July 2016, all adult immunocompromised patients with ARF admitted to the ICU were included in the study. Adjusted analyses included: (1) a hierarchical model with center as random effect; (2) propensity score (PS) matched cohort; and (3) adjusted analysis in the matched cohort. Results Overall, 1481 patients were included in this study of which 165 had neutropenia at ICU admission (11%). ARF etiologies distribution was significantly different between neutropenic and non-neutropenic patients, main etiologies being bacterial pneumonia (48% vs 27% in neutropenic and non-neutropenic patients, respectively). Initial oxygenation strategy was standard supplemental oxygen in 755 patients (51%), high-flow nasal oxygen in 165 (11%), non-invasive ventilation in 202 (14%) and invasive mechanical ventilation in 359 (24%). Before adjustment, hospital mortality was significantly higher in neutropenic patients (54% vs 42%; p = 0.006). After adjustment for confounder and center effect, neutropenia was no longer associated with outcome (OR 1.40, 95% CI 0.93–2.11). Similar results were observed after matching (52% vs 46%, respectively; p = 0.35) and after adjustment in the matched cohort (OR 1.04; 95% CI 0.63–1.72). Conclusion Neutropenia at ICU admission is not associated with hospital mortality in this cohort of critically ill immunocompromised patients admitted for ARF. In neutropenic patients, main ARF etiologies are bacterial and fungal infections

Ready-to-use food supplement, with or without arginine and citrulline, with daily chloroquine in Tanzanian children with sickle-cell disease: a double-blind, random order crossover trial

Background: Sickle-cell disease increases the risk of malnutrition. Low arginine and nitric oxide bioavailability are implicated in morbidity related to sickle-cell disease. Simple interventions are required, especially in low-income settings. We aimed to test the hypotheses that: (1) supplementary arginine, citrulline, and daily chloroquine increase bioavailable arginine and flow-mediated dilatation (FMD; maximal diameter change; FMDmax%), a measure of nitric oxide-dependent endothelial function; and (2) protein energy supplementation in the form of ready-to-use supplementary food (RUSF) improves the height-for-age and body-mass index-for-age Z-scores in children with sickle-cell disease. Methods: We performed a double-blind, random order crossover trial with two 4-month intervention periods (each followed by 4-month washout periods) in Muhimbili National Hospital in Dar-es-Salaam, Tanzania. We enrolled 119 children from the Muhimbili Sickle Cohort who were aged 8–12 years, naive to hydroxyurea, and had documented HbSS phenotype. Two formulations of RUSF (providing 500 kcal/day) were tested: basic (RUSF-b), with which children also received weekly chloroquine (150 mg or 225 mg chloroquine base, dependent on bodyweight); and vascular (RUSF-v), which was fortified with arginine and citrulline (designed to achieve mean intakes of 0·2 g/kg per day of arginine and 0·1 g/kg per day of citrulline), and with which children received daily chloroquine (maximum 3 mg chloroquine base/kg per day). Children were randomly allocated to receive either RUSF-b first or RUSF-v first and, after a washout period, were then given the other treatment. The primary outcomes in comparing the two RUSF formulations were mean plasma arginine, arginine to ornithine ratio, and arginine to asymmetric dimethylarginine ratio, and mean FMDmax%. The primary outcomes of the combined effect of both RUSF interventions were mean height-for-age Z-score and body-mass index-for-age Z-score. Analyses were done on the eligible intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01718054; and with ISRCTN74331412. Findings: Between Aug 9, 2012, and Feb 26, 2014, 145 children were randomised (71 children to RUSF-v first and 74 children to RUSF-b first) and 119 children were treated, of whom 114 children yielded complete data for all reported endpoints. The ratio of arginine to ornithine (mean of individual differences −8·67%, 95% CI −19·55 to 2·20; p=0·12) and the mean FMDmax% (1·00, −0·47 to 2·47; p=0·18) did not significantly differ between the RUSF-b and RUSF-v treatments. However, the arginine to asymmetric dimethylarginine ratio was significantly increased by RUSF-v compared with RUSF-b (56·26%, 31·13 to 81·38; p&lt;0·0001). In planned analyses that used mixed effects models to estimate the effect of each intervention compared with the participants at baseline or during washout periods, the arginine to asymmetric dimethylarginine ratio increased following both RUSF-v treatment (86%; p&lt;0·0001) and RUSF-b treatment (40%; p&lt;0·0001). However, FMDmax% was higher after treatment with RUSF-v (0·92; p&lt;0·0001) but not RUSF-b (0·39; p=0·22). Following either intervention (RUSF-b and RUSF-v, pooled) body-mass index-for-age Z-score (0·091; p=0·001) and height-for-age Z-score (0·013; p=0·081) increased compared with baseline and washout timepoints. In 83 participants in the treated population, there were 71 adverse events during the intervention, of which 21 (30%) were serious, and 81 adverse events during the washout periods, of which 26 (32%) were serious (p=0·31), including one patient who died in the second washout period. Interpretation: RUSF providing 500 kcal/day results in small weight gains in children with sickle-cell disease. However, even without arginine and citrulline fortification, RUSF seems to ameliorate arginine dysregulation and might improve endothelial function. Long-term studies are required to assess whether these physiological effects translate to improved clinical outcomes and better growth and development in patients with sickle-cell disease.
