Nutrition intake in critically ill patients with coronavirus disease (COVID-19): A nationwide, multicentre, observational study in Argentina.

INTRODUCTION: In 2020 the pandemic caused by SARS-COV-2 demanded an enormous number of healthcare resources in order to guarantee adequate treatment and support for those patients. This study aims to assess caloric and protein intake and evaluate its associations with relevant clinical outcomes in critically ill with coronavirus disease (COVID-19) patients. METHODS: A nationwide, multicentre prospective observational study including twelve Argentinian intensive care units (ICUs,) was conducted between March and October 2020. INCLUSION CRITERIA: Adult ICU patients>18 years admitted to the ICU with COVID-19 diagnosis and mechanical ventilation for at least 48h. Statistical analysis was carried out using IBM-SPSS© 24 programme. RESULTS: One hundred and eighty-five patients were included in the study. Those who died had lower protein intake (0.73g/kg/day (95% confidence interval (CI) 0.70-0.75 vs 0.97g/kg/day (CI 0.95-0.99), P<0.001), and lower caloric intake than those who survived (12.94kcal/kg/day (CI 12.48-13.39) vs 16.47kcal/kg/day (CI 16.09-16.8), P<0.001). A model was built, and logistic regression showed that factors associated with the probability of achieving caloric and protein intake, were the early start of nutritional support, modified NUTRIC score higher than five points, and undernutrition (Subjective Global Assessment B or C). The patients that underwent mechanical ventilation in a prone position present less caloric and protein intake, similar to those with APACHE II>18. CONCLUSIONS: Critically ill patients with COVID-19 associated respiratory failure requiring mechanical ventilation who died in ICU had less caloric and protein intake than those who survived. Early start on nutritional support and undernutrition increased the opportunity to achieve protein and caloric goals, whereas the severity of disease and mechanical ventilation in the prone position decreased the chance to reach caloric and protein targets.

Aporte calórico y macronutrimental de los menús infantiles de la comida rápida y convencional / Caloric and macronutrient contribution of the children's menu of fast and conventional food

The caloric and macronutrient contribution of the children's menu in fast food restaurants and conventional restaurants was analyzed, according to mealtimes and recommended intakes for children between 4 and 8 years old in a city in the Northeastern of Mexico with the highest childhood obesity rate in the world. This is an observational, descriptive and transversal study. The sampling was by convenience and directed when typical cases of children's menus were selected from 152 restaurants. The range of carbohydrates contribution of the children's menu varied from 53.8% to 97.9% of the recommendation; in any case the protein contribution was less than 82.2%. With regard to fats, contribution ranges were from 63% to 165.3%. These contributions increase considerably when they are analyzed by mealtimes: from 97.8% to 373.4%. In conclusion, fast food and conventional restaurants offer unhealthy meals in big portions to child population.

Se analizó el aporte calórico y de macronutrientes de me-nús infantiles en restaurantes de comida rápida y restaurantes convencionales según tiempos de comidas e ingesta recomendada para niños de 4 a 8 años en una ciudad del noreste mexicano que presenta una prevalencia de obesidad infantil de las más altas del mundo. Es un estudio observacional, descriptivo y transversal. El muestreo fue por conveniencia y dirigido al ser seleccionados casos típicos de menús infantiles de cadenas de restaurantes de mayor presencia (152 establecimientos). Los resultados muestran que el rango de aporte de hidratos de carbono varió del 53,8% a 97,9% de la recomendación; el aporte de proteína no fue menor al 82,2%; el aporte de lípidos fue de 63.0% a 165,3%. Estos aportes aumentan considerablemente al analizarlos por tiempos de comida: de 97,8% a 373,4%.

Uso de harina de cotiledón de algarrobo (Prosopis chilensis (Mol) Stuntz) como fuente de proteína y fibra dietética en la elaboración de galletas y hojuelas fritas / Use of algarrobo (Prosopis chilensis (Mol) Stuntz) flour as protein and dietary fiber source in cookies and fried chips manufacture

Los aminoácidos limitantes en la proteína de algarrobo chileno son isoleucina, treonina y metionina/cisteina. La mezcla de cereales y leguminosas, permite mejorar el balance aminoacídico, ya que las leguminosas tienen más lisina y los cereales son más ricos en aminoácidos azufrados. Debido al interés nutricional del cotiledón de algarrobo, se evaluó la incorporación de harina de cotiledón de algarrobo (HCA) en la elaboración de “snack” dulces y salados. Se prepararon galletas dulces y hojuelas fritas saladas con 0 por ciento, 10 por ciento y 20 por ciento de HCA. En las harinas se determinó, color, granulometría, humedad, composición proximal, lisina disponible, fibra dietética total, soluble e insoluble. A las galletas y hojuelas se les determinaron las mismas características físicas y químicas (excepto granulometría) que las harinas; además se determinó actividad de agua, peso y dimensiones y se calculó el aporte calórico. Se evaluó la calidad y aceptabilidad sensorial de ambos productos. Destaca el alto contenido de proteínas, lípidos, cenizas, fibra cruda (63,6; 10,2; 4,3 y 4,2 g/100g bms, respectivamente), lisina disponible (62,4 mg/g proteína) y fibra dietética total (24,2 g/100g bms) de la HCA. Tanto en las galletas como en las hojuelas con HCA, aumenta significativamente el contenido de proteínas, lípidos, cenizas, fibra cruda, lisina disponible (desde 15,5 a 19,3 y de 20,3 a 29,6 mg lisina/g proteína, respectivamente) y fibra dietética total (de 1,39 a 2,80 y de 1,60 a 5,60 g/100g bms, respectivamente). Todos los tratamientos de galletas fueron igualmente aceptados (“me gusta mucho”); las hojuelas, con 10 por ciento de HCA presentaron la mayor aceptabilidad (“me gusta medianamente”). Se puede concluir que la incorporación de HCA en la elaboración de galletas y hojuelas fritas aumenta el aporte de lisina disponible, su contenido de proteínas y fibra dietética, mejorando la relación fibra soluble/ insoluble, sin afectar sus características fisicas...

Limiting amino acids of the protein from chilean “algarrobo” are isoleucine, theronine and methionine/cyteine. Cereals and legume blends allow to improve the amino acid balance, since legume have more lysine, and cereals are richer in sulphur amino acids. Due to the nutritional interest of “algarrobo” cotyledons, the use of “algarrobo cotyledon” flour (ACF) in sweet and salty snack manufacture was evaluated. Cookies and fried salty chips with 0 percent, 10 percent and 20 percent ACF were prepared. Flours were analyzed for color, particle size, moisture, proximate composition, available lysine, and soluble, insoluble and total dietary fiber. Cookies and chips were analyzed for the same characteristics (except for particle size); besides there were determined water activity, weight and size of the units, and also, the caloric value was computed. Sensory quality and acceptance of both products were evaluated. It is noticeable the high amount of protein, lipids, ash, crude fiber (63.6; 10.2; 4.3 and 4.2 g/100g dmb, respectively), available lysine (62.4 mg/g protein) and total dietary fiber (24.2 g/100g dmb) of ACF. Both, cookies and chips with ACF, showed a significant increase in the amount of protein, lipids, ash, crude fiber and, available lysine (from 15.5 to 19,3 and from 20.3 a 29.6 mg lisina/g protein, respectively), and total dietary fiber (from 1.39 to 2.80 and from 1.60 a 5.60 g/100g dmb, respectively). All of the cookies trials were well accepted (“I like it very much”); chips with 10 percent of AFC showed the highest acceptance (“I like it”). It can be concluded that the use of ACF in cookies and chips manufacture increases the contribution of available lysine; their protein and dietary fiber content, improving the soluble/insoluble fiber ratio, without affect neither their physical nor their sensory acceptance.
