Acceptability and feasibility of a virtual community of practice to primary care professionals regarding patient empowerment: A qualitative pilot study

Background: Virtual communities of practice (vCoPs) facilitate online learning via the exchange of experiences and knowledge between interested participants. Compared to other communities, vCoPs need to overcome technological structures and specific barriers. Our objective was to pilot the acceptability and feasibility of a vCoP aimed at improving the attitudes of primary care professionals to the empowerment of patients with chronic conditions. Methods: We used a qualitative approach based on 2 focus groups: one composed of 6 general practitioners and the other of 6 practice nurses. Discussion guidelines on the topics to be investigated were provided to the moderator. Sessions were audio-recorded and transcribed verbatim. Thematic analysis was performed using the ATLAS-ti software. Results: The available operating systems and browsers and the lack of suitable spaces and time were reported as the main difficulties with the vCoP. The vCoP was perceived to be a flexible learning mode that provided up-to-date resources applicable to routine practice and offered a space for the exchange of experiences and approaches. Conclusions: The results from this pilot study show that the vCoP was considered useful for learning how to empower patients. However, while vCoPs have the potential to facilitate learning and as shown create professional awareness regarding patient empowerment, attention needs to be paid to technological and access issues and the time demands on professionals. We collected relevant inputs to improve the features, content and educational methods to be included in further vCoP implementation. Trial registration: ClinicalTrials.gov, NCT02757781.

Evaluación de un programa de Programa de Intervención Nutricional en pacientes con enfermedad renal crónica avanzada (ERCA)

Introducción y Objetivos: La Enfermedad Renal Crónica Avanzada (ERCA) se asocia a una elevada prevalencia de malnutrición. La práctica habitual en estos pacientes va dirigida a reducir la ingesta proteica, recomendación que podría favorecer esta situación. Por ello, el objetivo de este estudio fue evaluar el efecto de un programa de intervención nutricional (PIN) sobre la función renal y el estado nutricional en pacientes con ERCA. Pacientes y Métodos: Se diseñó un estudio longitudinal y prospectivo con 93 pacientes (53,7% hombres, 66 ± 17años) que participaron en un PIN durante 6 meses con visitas mensuales. Al inicio y al final de la intervención se evaluaron: estado nutricional en función de los criterios de Chang, datos antropométricos, dietéticos y bioquímicos (albúmina, prealbúmina, aclaramiento de creatinina, fósforo y potasio séricos, Colesterol-total, LDL, HDL, triglicéridos y PCR). Resultados: Tras el PIN la ingesta calórica disminuyó en los normonutridos (1833 ± 318 vs 1571 ± 219 kcal p < 0,001) y se mantuvo en los malnutridos. Se redujo significativamente la ingesta proteica (69,9 ± 16,6 vs 54,9 ± 11 g p < 0,001), potasio (2938 ± 949 vs 2377 ± 743 mg, p < 0,0001) y fósforo (1180 ± 304 vs 946,6 ± 211 mg, p < 0,0001). Un 16,5% requirió suplementación. El porcentaje de pacientes que presentaba malnutrición según criterios de Chan disminuyó tras el PIN (41,7 % (27,8% leve, 10,10% moderada y 3,8% grave) vs 16,8% (8% leve, 5% moderada y 3,8% grave)). Tras el PIN incrementó significativamente el aclaramiento de creatinina (17,8 ± 5,2 vs 19,4 ± 6,9 ml/min, p < 0,01), albúmina (3,3 ± 0,5 g/dL vs 3,5 ± 0,4 g/dL, p < 0,05) y disminuyó el potasio sérico (4,8 ± 0,6 vs 4,5 ± 0,5 mmol/L, p < 0,05), Colesterol Total (179,8 ± 44,3 vs 170,0 ± 15,1 mg/dL, p < 0,05), LDL colesterol (113,2 ± 37,0 vs 108,3 ± 27,3 mg/dL, p < 0.01) y triglicéridos (141,9 ± 60,8 vs 129,9 ± 52,7 mg/dL, p < 0,05 Introducción y Objetivos: La Enfermedad Renal Crónica Avanzada (ERCA) se asocia a una elevada prevalencia de malnutrición.

The habitual continuous dietary restrictions used in clinical practice. increased the malnutrition risk. The aim of this study was to evaluate the effects of a Nutritional intervention Program (NIP) on renal function and nutritional status in patients with ACKD. Patients and Methods: 93 patients, (53.7% men, 66 ± 17 years) were included in a prospective longitudinal study. The patients recived a NIP during 6 months with mensual visits. At baseline and six months the outcome assessed were: nutritional status by Chang criteria, anthropometric, dietetic and biochemical parameters (albumin, prealbumin, creatinine clearance, serum phosphorus, potassium, total-Cholesterol, LDL, HDL, triglycerides, and PCR). Results: After intervention, caloric intake decreased in nourished patients (1833 ± 318 vs 1571 ± 219 kcal p = .001). and it was constant in malnourished patients. The intake of protein (69,9 ± 16,6 vs 54,9 ± 11 g p < 0.001), potassium (2938 ± 949 vs 2377 ± 743 mg p < 0.001) and phosphorus (1180 ± 304 vs 946,6 ± 211 mg p < 0.001) significantly decreased. 16.5% patients required supplementation. A total of 41.7% of patients were malnourished at baseline (27.8% mild, 10.10% moderate and 3.8% severe), and 16.8% at the end (8% mild, 5% moderate and 3.8% severe) by Chang criteria. At the end of NIP, patients significantly increased creatinine clearance (17,8 ± 5,2 vs 19,4 ± 6,9 ml/min, p < 0,01), albumin (3,3 ± 0,5 vs. 3,5 ± 0,4 g/dL, p < 0,05), and decreased serum potassium (4,8 ± 0,6 vs 4,5 ± 0,5 mmol/L, p < 0,05), total cholesterol (179,8 ± 44,3 vs 170,0 ± 15,1 mg/dL, p < 0,05), LDL (113,2 ± 37,0 vs 108,3 ± 27,3 mg/dL, p < 0.01) and tryglicerides (141.9 ± 60.8 vs 129.9 ± 52.7 mg/dL, p < 0.05). Conclusions: The study reflected a NIP usefulness in the nutritional status and renal function improvements within an interdisciplinary framework during ACKD consultation

Precipitation of particles using combined high turbulence extraction assisted by ultrasound and supercritical antisolvent fractionation

High Turbulence Extraction Assisted by Ultrasound combined with Supercritical Antisolvent Fractionation (SAF) was done to intensify the recovery of bixin and phenolic compounds from semi-defatted annatto seeds. Annatto seeds are extensively used due to its colorant properties and bioactive potential in human health. Modifications were performed in the SAF experimental apparatus in order to prevent losses of product. Results show that supercritical fractionation resulted in particle yields between 72.2–80.5%, 20–50% phenolics, and 66% bixin.3549CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP302423/2015-088882.305824/2013-012015/13299-
