Food intake and bioimpedance analysis

•  Bioimpedance analysis is a simple, safe, and relatively inexpensive method of assessing body composition.
• A study aim to identify whether  libitum food and liquid intake interfere with body composition parameters estimated via bioimpedance.
• The evaluations were carried out over two days.
• First day: hydration protocol was carried. Second day: food protocol.
• The results shows that libitum food and liquid intake do not cause a change above clinically acceptable levels in the fat percentage estimated by bioimpedance.

Omega-3 and ARDS

• An interesting meta-analysis on 12 randomized control trials have performed  to evaluate the clinical benefits of omega-3 polyunsaturated fatty acids (PUFA) administration on gas exchange, and clinical outcomes in acute respiratory distress syndrome (ARDS) patients.
• They concluded that omega-3 PUFAs in enteral immunomodulatory diets of critically ill patients with ARDS might decrease the severity of disease by improving early and late ratios of partial pressure of arterial oxygen (PaO2) to fraction of inspired oxygen (FiO2).

What is 3 GO risk?

• 3GO, defined as the simultaneous presence of hypertension, hyperglycemia, and dyslipidemia.
• A study aim to determine polygenetic risk scores(PRS) for 3GO risk and the interactions between PRS and lifestyle habits for 3GO risk in Korean adults aged 40-77 recruited from the urban hospital cohort of the Korean Genomic and Epidemiological Study.
• The results concluded that reducing alcohol intake, exercising regularly, and quitting smoking might be effective for reducing 3GO risk in individuals with a high PRS.

Ultra processed diet and oxidative stress

• In recent years, the increase in ultra-processed food consumption in the world has been increasing.
• The present review aims to analyze the connection between an ultra-processed diet, systemic oxidative stress, and immune tolerance, as a contribution to the scientific evidence on the impact of oxidative stress on health and the possible risk of infections, since its consideration is an important reference in the association of the current eating pattern and the immune response.

Glim criteria and esophageal cancer

• A prospective study aimed to investigate the property of the Global Leadership Initiative on Malnutrition (GLIM) criteria for malnutrition assessment in esophageal cancer patients undergoing esophagectomy.
• The preoperative metabolic characteristics, postoperative morbidities, and survival outcomes were investigated for GLIM-defined malnutrition.
• The results show that GLIM criteria showed good properties in diagnosing and classifying malnutrition in esophageal cancer patients undergoing esophagectomy.

CT and LSMM

•  Low skeletal muscle mass (LSMM) can be assessed by imaging modalities.
• It is associated with several clinically relevant factors in critical ill patients.
• A study  aim to establish the effect of CT-defined LSMM on short-term mortality in critical ill patients based on a large patient sample.
• The results indicate that CT-defined LSMM is highly prevalent in critically ill patients, has a relevant effect on short-term mortality, and should be included as relevant prognostic biomarker into clinical routine.
