ABSTRACT

OBJECTIVE: The present study aimed to evaluate the association between muscle mass variation, estimated by different equations, during hospitalization with the energy and protein intake and clinical and nutrition outcomes of patients using nutrition support. METHODS: A prospective observational study with patients older than 18 years in use of enteral and/or parenteral nutrition therapy and monitored by the Nutritional Therapy Committee between December 14, 2021, and December 14, 2022. Data were collected from the electronic records and were applied in 11 equations to estimate the four different portions of muscle mass of patients receiving nutrition support at the beginning and the end of hospitalization. RESULTS: A total of 261 patients were evaluated, with a median age of 61.0 (49.0-69.75) years, and 106 were women (40.6%). According to the nutrition diagnosis, several participants had severe malnutrition (39.5%). The most muscle mass estimation equations indicated a reduction of muscle mass during hospitalization. All patients presented negative energy and protein balances during hospitalization, but greater protein intake increased the lean soft tissue. Also, the greater the number of infections, metabolic complications, and scheduled diet interruption, the greater was the chance of losing muscle mass. CONCLUSION: There can be an association between the variation in muscle mass and energy and protein intake during hospitalization of patients using nutrition support. In addition, variation in muscle mass was associated with complications from nutrition support. The results emphasize the importance of anthropometric measurements to estimate muscle mass when other methods are not available.

ABSTRACT

CONTEXT: Reduced muscle mass is linked to poor outcomes in both inpatients and outpatients, highlighting the importance of muscle mass assessment in clinical practice. However, laboratory methods to assess muscle mass are not yet feasible for routine use in clinical practice because of limited availability and high costs. OBJECTIVE: This work aims to review the literature on muscle mass prediction by anthropometric equations in adults or older people. DATA SOURCES: The following databases were searched for observational studies published until June 2022: MEDLINE, Embase, Scopus, SPORTDiscus, and Web of Science. DATA EXTRACTION: Of 6437 articles initially identified, 63 met the inclusion criteria for this review. Four independent reviewers, working in pairs, selected and extracted data from those articles. DATA ANALYSIS: Two studies reported new equations for prediction of skeletal muscle mass: 10 equations for free-fat mass and lean soft tissue, 22 for appendicular lean mass, 7 for upper-body muscle mass, and 7 for lower-body muscle mass. Twenty-one studies validated previously proposed equations. This systematic review shows there are numerous equations in the literature for muscle mass prediction, and most are validated for healthy adults. However, many equations were not always accurate and validated in all groups, especially people with obesity, undernourished people, and older people. Moreover, in some studies, it was unclear if fat-free mass or lean soft tissue had been assessed because of an imprecise description of muscle mass terminology. CONCLUSION: This systematic review identified several feasible, practical, and low-cost equations for muscle mass prediction, some of which have excellent accuracy in healthy adults, older people, women, and athletes. Malnourished individuals and people with obesity were understudied in the literature, as were older people, for whom there are only equations for appendicular lean mass. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration number CRD42021257200.

ABSTRACT

BACKGROUND: Cardiovascular diseases represent the leading cause of death worldwide, in addition to having a direct negative impact on quality of life, functional capacity and nutritional status. Studies show high prevalence of malnutrition in patients undergoing cardiac surgery. It is known that cardiac surgery can also lead to changes in nutritional status, through surgical trauma, systemic inflammation and, often, delay in the initiation of nutritional support. On the other hand, the role of nutritional support as a driver of clinical outcomes in different surgical populations is well described in the literature. OBJECTIVE: To review the literature in order to assess the effect of perioperative oral or enteral nutritional support on clinical outcomes of cardiac patients undergoing cardiac surgery. METHODOLOGY: The search was conducted in February 2021 in the following databases: EMBASE, PubMed/MEDLINE, Scopus and Web of Science. Randomized clinical trials (RCT) and retrospective studies were selected, carried out with patients with heart disease, undergoing cardiac surgery and aged 18 years or over. The Outcomes of interest were: length of hospital stay, length of stay in the ICU, time on ventilatory support, mortality rate, clinical complications and use of vasoactive drugs in the postoperative period. RESULTS: Ten studies were included in this systematic review, of which 7 were RCTs and 3 were cohorts. The most prevalent surgery was myocardial revascularization. Six studies evaluated oral nutritional support, two enteral nutritional support and two analyzed both. Two studies found a significant reduction in the length of hospital and ICU staying associated with preoperative intake of carbohydrate-based beverages. Only one study observed a significant reduction in the requirement for ventilatory support after cardiac surgery, after preoperative carbohydrate-based drinks and early postoperative enteral nutrition. There was no influence of nutritional support on mechanical ventilation length and mortality. CONCLUSION: Most studies showed that nutritional support did not reduce hospital and ICU staying. Nutritional support benefits were demonstrated in studies that offered preoperative oral carbohydrate drinks. No association was observed between nutritional support and duration of mechanical ventilation or mortality rate. Most studies did not find any influence of nutritional support on the need and/or dosage of vasoactive drugs in the postoperative period of cardiac surgery.

ABSTRACT

The development of cardiometabolic diseases is related to conditions such as obesity, abdominal fat, insulin resistance, diabetes mellitus, elevated blood pressure and changes in lipid profile. The whole of Trans Fatty Acid (TFA) intake is associated with the increase of cardiometabolic risk factors. There are two main sources of TFA, the ruminant TFA (rTFA) which are produced by biohydrogenation in animal's rumen, and the industrial TFA (iTFA), produced by hydrogenation of vegetable oils, the individual effect of each group is still controversial. The aim of this study was to analyze the effect of industrially and ruminants TFA intake on cardiometabolic risk in adults. It was carried out a systematic search of the literature in October 2019 and two independent authors selected and extracted data from articles. After the selection process, nine clinical trials were included, and summary tables were constructed to present data for all outcomes. The results showed that both sources of TFA can increase cardiometabolic risk parameters, especially lipid profile. At levels up to 1.5%-7% of energy, the effect of rTFA seems to be greater than iTFA and it seems to be greater in women. However, rTFA seems to be less harmful than iTFA for High Density Lipoprotein cholesterol, although for total cholesterol and Low density Lipoprotein cholesterol it may be worse. In summary, both sources of TFA can increase cardiometabolic risk parameters, especially lipid profile. However, the dose of TFA and the whole composition of the food must be considered.
