Critical nutricion

INTRODUCTION: vegan diets are currently an essential topic of discussion because they are recognized as a prototype of a healthy diet but are also associated with deficits in the intake of critical nutrients such as protein. Evaluating the factors that influence the deficit in their intake in vulnerable populations such as university students represents an important topic of interest, considering that this is one of the groups where veganism is most popular. Given this, the present study aimed to determine the degree of protein sufficiency and its associated factors in a sample of Chilean vegan university students...

AIM: critical illness often leads to malnutrition and diaphragmatic dysfunction (DD), common in intensive care units (ICU). Ultrasonography (US) is a potent tool for detecting DD. This study examines the connection between malnutrition risk and DD in ICU patients using ultrasonographic diaphragm measurements in medical ICU patients. METHODS: we assessed nutritional risk using risk screening tools and mid-upper arm circumference measurements (MUAC). Diaphragm atrophy (DA) and DD were evaluated by measuring diaphragmatic excursion (DE), thickness, and thickening fraction (TF) by US...

Introduction: variants of the NUTRIC score with or without inflammatory biomarkers, modified without interleukin 6 (IL-6) (NUTRICm), with C-reactive protein (CRP) instead of IL-6, dichotomous (NUTRICpcr1) or in tertiles (NUTRICpcr2), were proposed to assess nutritional risk (NR) in critical patients. However, the assessment of the high NR might not be uniform between these scores. Objectives: to compare the assessment of the high NR by NUTRICm and the two variants of the NUTRICpcr. Material and methods: analysis of a prospective cohort of patients ventilated prior to COVID-19...

Acute kidney injury (AKI) is common in critically ill patients. There is no specific pharmacological treatment for established severe AKI. Therefore, the conventional therapeutic strategy is limited to the use of kidney replacement therapy (KRT) to maintain homeostasis. Hybrid therapies optimize the advantages of intermittent and continuous modalities of KRT, combining lower hourly efficiency, longer application time, at lesser cost, but also adding different physicochemical principles of extracorporeal clearance...

In the 1970s, acute peritoneal dialysis (PD) was widely accepted for the treatment of acute kidney injury (AKI), but this practice has declined in favor of extracorporeal therapies, mainly in developed world. The lack of familiarity with the use of PD in critically ill patients has also led to a lack of use even among those receiving maintenance PD. Renewed interest in the use of PD for AKI therapy has emerged due to its increasing use in low- and middle-income countries due to its lower cost and minimal infrastructural requirements...

Continuous renal replacement therapy (CRRT) is the main extracorporeal kidney support therapy used in critical ill patients in the intensive care unit (ICU). Since its conceptualization ~50 years ago, there have been major improvements in its technology and utilization. The last decade, and particularly since the COVID-19 pandemic, has been marked by a growing interest and demand of CRRT in worldwide ICUs. This has underpinned the need for improvements in nomenclature and process standardization, optimization of CRRT deliverables, and the development and validation of key performance indicators...

INTRODUCTION: Nutrition during the complementary feeding period (6-23 months) is critical to ensure optimal growth and reduce the risk of diet-related disease across the life course. Strategies to reduce multiple forms of malnutrition (stunting, overweight/obesity and anaemia) in infants and young children (IYC) are a key priority in low-income and middle-income countries, including Peru. This study aims to co-design and develop prototypes for interventions to address the multiple forms of malnutrition in IYC in urban Peru, using a participatory design approach...

INTRODUCTION: the interaction between immunity and nutrition is complex and multifaceted. Micronutrients, including vitamins and minerals, are essential for immune function. In turn, immune function and lifestyle habits can affect nutritional needs and micronutrient utilization, creating an interdependence between nutrition and immunity that can be modulated by both external and internal factors. OBJECTIVES: to examine the relationship between micronutrient intake and immune function, and how debilitating factors such as aging, disease, and stress can impact this relationship...

The first 1,000 days of life, from conception to two years of age, are a critical time window for human growth and development, since the interaction of different factors can generate relevant changes in different structures and functions of the organism, both at short and long term. Most of the studies in this area have been carried out in the prenatal and neonatal period. Some of the most relevant factors that can affect immune development at this time are smoking, maternal obesity and inadequate intake of micronutrients during pregnancy...

Blood purification as an adjunctive therapy has been studied for several decades. In this review, we will focus on the most recent studies, particularly on adsorption techniques. These include hemofilters with adsorptive membranes, both endotoxin-specific and non-specific. In addition, we will discuss sorbents that target endotoxins, as well as devices that non-selectively capture viruses and bacteria. For each technique, we will also explore the reasons why blood purification methods have thus far failed to improve survival...

INTRODUCTION: there is a wide variety of enteral nutrition and infant formulas or preparations. Consultation of related information must be performed using the tools provided by each laboratory, which makes critical vision and comparison between them very arduous. OBJECTIVE: to describe the development of NEmecum as the first website that allows a directed and independent search for enteral nutrition formulas and infant formulas, to analyze the current nutritional range in Spain, and to evaluate the data usage of the tool...

INTRODUCTION: Mexico is a country with a high prevalence of overweight and obesity. However, social feeding programs often target only undernutrition in vulnerable population groups. OBJECTIVE: to estimate the association of overweight and obesity (OW) with participation in a conditional cash transfers (CCT) program and other social feeding programs in women 15-49 years of age within the most economically vulnerable population in Mexico. METHODS: anthropometric data, as well as information on participation in social feeding programs, household food insecurity and sociodemographic variables, were analyzed for women aged 15-49 living in localities of under 100,000 inhabitants in Mexico...

INTRODUCTION: Nutritional risk is a parameter used to diagnose the level of risk that the patient has of developing adverse effects that impact their nutritional status. There are studies that associate nutritional risk with clinical evolution. OBJECTIVE: To evaluate the association of nutritional risk with clinical variables related to the severity of critically ill patients with COVID-19. METHODS: Adult ICU patients with COVID-19 were included, and the relationship between nutritional risk (NUTRICm score) and the variables: ICU stay, Invasive Mechanical Ventilation (IMV), acute renal failure, secondary infection, and mortality were analyzed...

Nutritional support in adult patients receiving extracorporeal membrane oxygenation (ECMO) therapy is controversial. Although there are guidelines for the NS (Nutritional support) in pediatric patients with ECMO, in adults these guidelines are not available for the use, type, route and timing of nutritional therapy. In critically ill patients it is well known that early enteral nutrition is beneficial, however there is the possibility that in patients with ECMO early enteral nutrition leads to gastrointestinal complications...

INTRODUCTION: The critical patient affected by SARS-CoV-2 is at risk of malnutrition. The need to avoid volume overload and manoeuvres that delay reaching nutritional requirements such as pronation make the nutritional approach to these patients complex. To ensure adequate treatment, a nutritional support protocol was developed as a clinical practice guideline adapted to the COVID-19 patient. OBJECTIVE: To describe and analyse the results of introducing a nutritional support protocol aimed at SARS-CoV-2 patients admitted to the intensive care unit (ICU) of the Consorcio Hospital General Universitario de Valencia (CHGUV) from March to May 2020...

INTRODUCTION: In critically ill patients, nutritional support is a challenge in terms of both estimating their requirements and ensuring adherence to the prescribed treatment. OBJECTIVE: To assess the association between requirements, prescription and adherence to energy and protein supplementation based on the phase of disease in critically ill patients. SAMPLE AND METHODS: We conducted a prospective, observational and analytical study in patients aged 0-18 years admitted to the paediatric intensive or intermediate care unit in 2020-2021...

INTRODUCTION: The optimal intake to improve protein metabolism without producing adverse effects in seriously ill infants has yet to be established. The aim of our study was to analyse whether an increased protein intake delivered through enteral nutrition would be associated with an improvement in nitrogen balance and serum protein levels in critically ill infants. METHODS: We conducted a multicentre, prospective randomized controlled trial (December 2016-June 2019)...

The challenge of assessing a patient's nutritional status and its evolution during treatment. From critical patients to outpatients (II).

INTRODUCTION: the risk and/or prognosis of COVID-19, caused by the SARS-CoV-2 virus, have been related to chronic diseases such as obesity, diabetes mellitus, and cardiovascular diseases, with poor-quality diet being a predisposing factor for these diseases. OBJECTIVE: to synthesize the scientific evidence on the effect of diet on the risk of SARS-CoV-2 infection and severe COVID-19. METHODS: a systematic review was carried out following the PRISMA guidelines...
