ObjectiveThere is little evidence of real-life outcomes of dietary supplementation with high-dose docosahexaenoic acid (DHA) and carotenoids in patients with diabetic retinopathy (DR). We assessed the effect of supplementation with DHA triglyceride (1,050 mg/d) + xanthophyll carotenoid multivitamin on macular function in nonproliferative DR.MethodsAsymptomatic patients with nonproliferative DR were included in a prospective controlled study and assigned (1:1) to the DHA supplementation group or the control group. Macular sensitivity and macular integrity area were the main outcome measures. Functional vision measures (macular function [MAIA™ CenterVue], best-corrected visual acuity), structural retinal measures (central subfield macular thickness), and biochemical parameters (plasma total antioxidant capacity, DHA content of the erythrocyte membrane, and plasma IL-6) were evaluated at baseline and after 45 and 90 days of DHA supplementation.ResultsThe study included 24 patients (48 eyes) (12 patients, 24 eyes in each group). Baseline clinical characteristics of patients in both groups were similar. Macular sensitivity increased from a mean (SD) of 25.9 (2.4) dB at baseline to 27.3 (2.3) dB at 90 days (P=0.030) in the DHA group only (between-group differences P<0.19). The macular integrity index decreased from 71.2 (33.2) at baseline to 63.5 (36.4) at 45 days and to 51.6 (35.9) at 90 days (P=0.002) in the DHA group only (between-group differences P<0.05). Best-corrected visual acuity and central subfield macular thickness did not vary significantly in any of the comparisons and in none of the groups. DHA content of erythrocyte membrane and total antioxidant capacity levels increased significantly only in the DHA group. Plasma IL-6 levels decreased significantly only in the DHA group.ConclusionIn an early stage of DR, supplementation with high-dose DHA plus xanthophyll carotenoid multivitamin during 90 days was associated with a progressive and significant improvement of macular function measured by microperimetry. Biochemical changes supported the effect of DHA.

Background Vertical jumps can be used to assess neuromuscular status in sports performance. This is particularly important in Cerebral Palsy Football (CP Football) because players are exposed to high injury risk, but it may be complicated because the gold standard for assessing jump performance is scarce in field evaluation. Thus, field techniques, such as mobile apps, have been proposed as an alternative method for solving this problem. Objective This study aims to evaluate the reliability of the measures of the MyJump2 app to assess vertical jump performance in professional CP Football. Methods We assessed 40 male CP Football athletes (age 28.1 [SD 1.4] years, weight 72.5 [SD 6.2] kg, and height 176 [SD 4.2] cm) through the countermovement jump (CMJ) and squat jump (SJ) using a contact mat. At the same time, we assessed the athletes using the MyJump2 app. Results There were no significant differences between the instruments in SJ height ( P =.12) and flight time ( P =.15). Additionally, there were no significant differences between the instruments for CMJ in jump height ( P =.16) and flight time ( P =.13). In addition, it was observed that there were significant and strong intraclass correlations in all SJ variables varying from 0.86 to 0.89 (both P <.001), which was classified as “almost perfect.” Similar results were observed in all variables from the CMJ, varying from 0.92 to 0.96 (both P ≤.001). Conclusions We conclude that the MyJump2 app presents high validity and reliability for measuring jump height and flight time of the SJ and CMJ in CP Football athletes.

Introducción: El objetivo del presente estudio fue evaluar si la calidad de la pasta es decisiva para controlar el hambre y la saciedad en comparación con el arroz.Material y métodos: n = 16 (8 hombres, 8 mujeres). El efecto sobre el apetito y la saciedad de dos pastas de diferente calidad y también del arroz se determinó mediante mediciones repetidas. Los sujetos entraron en ayunas y fueron evaluados en diferentes momentos después de la ingesta del producto investigado durante 240 minutos, comieron un bufet ad libitum y fueron evaluados nuevamente en el minuto 270. Aspectos relacionados con la saciedad (hambre, saciedad, saciedad y deseo de comer) fueron evaluados por escala visual analógica (VAS), puntaje global de apetito (OAS), área bajo curva (AUC) y cociente de saciedad (SQ).Resultados: La OEA informada por los voluntarios antes de la ingesta de productos bajo investigación no difirió significativamente, por lo que los parámetros de referencia no sesgaron las mediciones posteriores. El AUC después de 60 minutos fue mayor después de la ingesta de arroz (2.355 ± 1.556%/min) en comparación con ambos tipos de pasta. Por otro lado, se obtuvieron valores similares entre los dos tipos de pasta (pasta A = 1.808 ± 1.329%/min; pasta B = 1.774 ± 1.370%/min). Además, el AUC informado por los voluntarios después de 240 minutos fue mayor después de la ingesta de arroz (12.424 ± 6.187%/min) en comparación con ambos tipos de pastas (pasta A = 10.292 ± 5.410%/min; pasta B = 9.976 ± 5.589%/min). Además, la SQ fue menor para el arroz (1,90 ± 4,29%/kcal) que para ambas pastas (pasta A = 4,73 ± 4,95%/kcal; pasta B = 4,40 ± 5,14%/kcal).Conclusiones: Ambas variedades de pasta mostraron resultados de saciedad más altos que el arroz, sin diferencias significativas entre ellos. Además, la diferencia entre arroz y pasta fue mayor dentro de los 60 minutos posteriores a la ingestión.
