Efecto de una suplementación láctea con ácido linoleico conjugado sobre el control de peso y la composición corporal de personas sanas con sobrepeso

Introduction: Conjugated linoleic acids (CLAs) have shown beneficial effects in weight control therapy however this relation is not clear. Objetive: The aim of the study was to examine the effects and safety of 3 g of a 1:1 mix of c9-t11 and t10-c12 on weight control and body composition in healthy overweight individuals. Methods: A prospective, placebo-controlled, randomised double-blind, parallel clinical trial lasting 24 weeks was carried out in 38 volunteers (29w, 9m) aged 30-55 years and BMI ≥27-<30 kg/m2 who consumed 200 ml/day of skimmed milk with 3g of CLAs or 3g olive oil (placebo). Anthropometric, biochemical and dual x-ray absorptiometry (DXA) tests were measured. Diet and physical activity were assessed. Results: Subjects maintained their habitual dietary and exercise patterns over the study. Only CLA group showed a significant decrease in weight (74.43 ± 10.45 vs 73.54 ± 11.66 kg, p = 0.029) and waist circumference (91.45 ± 10.33 vs 90.65 ± 9.84 cm, p = 0.012) between baseline and end of the study. BMI and waist height ratio decreased (28.44 ± 1.08 vs 27.81 ± 1.43 kg/m2, p = 0.030 and 0.57 ± 0.05 vs 0.56 ± 0.04 p = 0.013 respectively) in CLA group at the end. CLA group experienced a reduction in total fat mass after 24 weeks (38.62 ± 5.02 vs 36.65 ± 5.64%, p = 0.035). No decrease was observed in Control group. HOMA index had no changes. Conclusions: The consumption of skimmed milk enriched with 3g of a 1:1 mixture of c9-t11 and t10-c12 for 24 weeks led to a decrease in body weight and total fat mass in healthy, overweight subjects who maintained habitual diets and exercise patterns. No adverse effects were observed.

Objetivo: El propósito de este estudio fue examinar los efectos y la seguridad de 3 g de una mezcla 1:1 de c9-t11 y t10-c12 sobre el control de peso y la composición corporal en individuos sanos con sobrepeso. Métodos: Se realizó un estudio clínico prospectivo, de grupos paralelos, de distribución aleatoria, a doble ciego y con control placebo, de 24 semanas de duración, en 38 voluntarios (29 mujeres, 9 hombres) con edades de 30-55 años y un IMC ≥27- < 30 kg/m2 que consumieron 200 ml/día de leche desnatada con 3 g de ALC o 3 g de aceite de oliva (placebo). Se midieron datos de antropometría, bioquímica y absorciometría dual de rayos X (DXA). Se evaluaron la dieta y la actividad física. Resultados: Los sujetos mantuvieron sus patrones habituales de dieta y ejercicio a lo largo del estudio. Sólo el grupo de ALC mostró una reducción significativa del peso (74,43 ± 10,45 vs 73,54 ± 11,66 kg, p = 0,029) y de la circunferencia de la cintura (91,45 ± 10,33 vs 90,65 ± 9,84 cm, p = 0,012) entre el periodo basal y el final del estudio. El IMC y el cociente cintura/talla disminuyeron (28,44 ± 1,08 vs 27,81 ± 1,43 kg/m2, p = 0,030 y 0,57 ± 0,05 vs 0,56 ± 0,04 p = 0,013, respectivamente) en el grupo ALC al final del estudio. El grupo ALC experimentó una reducción de la masa grasa total tras 24 semanas (38,62 ± 5,02 vs 36,65 ± 5,64 %, p = 0,035). No se observó reducción en el grupo control. El índice HOMA no experimentó cambios. Conclusiones: El consumo de leche desnatada enriquecida con 3 g de una mezcla 1:1 de c9-t11 y t10-c12 durante 24 semanas produjo un descenso del peso corporal y la masa grasa total en sujetos sanos con sobrepeso que mantuvieron sus patrones habituales de dieta y ejercicio físico. No se observaron efectos adversos. Registrado con el identificador núm. NCT01503047 en ClinicalTrials. govThis study was funded by CAPSA (Corporación Alimentaria Peñasanta

Exploring long COVID condition in Latin America: Its impact on patients’ activities and associated healthcare use

"Background: Studies exploring long COVID condition (LCC) in low- and middle-income countries are scarce. Further characterization of LCC patients experiencing activity limitations and their associated healthcare use is needed. This study aimed to describe LCC patients’ characteristics, its impact on activities, and associated healthcare use in Latin America (LATAM). Participants: Individuals who (cared for someone or) had COVID-19 and could read, write, and comprehend Spanish and lived in a LATAM country were invited to complete a virtual survey. Sociodemographic characteristics, COVID-19 and LCC symptoms, activity limitations, and healthcare use. Results: Data from 2,466 people from 16 countries in LATAM were analyzed (females = 65.9%; mean age of 39.5 ± 53.3 years). 1,178 (48%) of the respondents had LCC symptoms (≥3 months). These were more likely to have COVID-19 earlier in the pandemic, were older, had no COVID vaccines, had more comorbidities, needed supplementary oxygen, and reported significantly more COVID-19 symptoms during the infectious period. 33% of the respondents visited a primary care provider, 13% went to the emergency department, 5% were hospitalized, 21% visited a specialist, and 32% consulted ≥1 therapist for LCC symptoms mainly extreme fatigue, sleep difficulties, headaches, muscle or joint pain, and shortness of breath with activity. The most consulted therapists were respiratory therapists (15%) and psychologists (14%), followed by physical therapists (13%), occupational therapists (3%), and speech pathologists (1%). One-third of LCC respondents decreased their regular activities (e.g., work, school) and 8% needed help with activities of daily living (ADLs). LCC respondents who reduced their activities reported more difficulty sleeping, chest pain with activity, depression, and problems with concentration, thinking, and memory, while those who needed help with ADLs were more likely to have difficulty walking, and shortness of breath at rest. Approximately 60% of respondents who experienced activity limitations sought a specialist and 50% consulted therapists. Conclusions and relevance: Results supported previous findings in terms of the LCC demographics, and provided insight into LCC impact on patients’ activities and healthcare services used in LATAM. This information is valuable to inform service planning and resource allocation in alignment with the needs of this population.

Development and Application of Bioactive Bi-Layer Edible Films Based on Starch and LAB-Fermented Whey and/or Mango Solution

This study aimed to develop bioactive bi-layer edible films based on starch (primary layer) and LAB-fermented whey and/or mango pulp powder solutions (secondary layer). Bioactive bi-layer edible films were evaluated for their physical properties, mechanical properties, antioxidant capacity, and Lactobacillus rhamnosus availability for 28 days (4 and 20 °C). Selected bioactive bi-layer edible film was applied to sushi to evaluate its sensory acceptance. The results indicated that bi-layer edible films based on LAB-fermented whey/mango solutions presented a higher quantity of phenolic compounds (95.87–107.67 mg GAE/100 g) and higher antioxidant capacity (74.84–77.64%). In addition, the higher viability (106–107 CFU/g) of L. rhamnosus after edible film production was obtained in those formulated with whey. After the storage period, the antioxidant capacity of all edible films was significantly affected by the storage time, while edible films containing whey in their formulation and stored at 4 °C had a L. rhamnosus count higher than 6 log cycles, which is the minimum required threshold to exert its beneficial effects in humans. The sushi covered with the selected bi-layer edible film was well accepted by the consumers, showing acceptance values between “I like it” and “I like it much”. Therefore, the developed bi-layer edible films can serve as an alternative for adding health-promoting compounds to sushi with an adequate sensory acceptance of the consumers
