“…Finally, Venancio et al [38] found that in LSG group (but not in the RYGB one), PhA was negatively correlated with the decrease of advanced oxidation protein products levels. Another paper found that PhA was positive related with serum transthyretin [36].…”

“…Seven papers assessed changes of PhA values following bariatric surgery by comparing values before and from 6 weeks to 2 years after intervention [32e38,42]. Four studies have evaluated patients treated with Laparoscopic Sleeve Gastrectomy (LSG) or Roux-en-Y Gastric Bypass (RYGB) [34,35,37,38], two studies RYGB only [36,42], one LSG [33] and one laparoscopic gastric banding (LGB) [32].

“…In five papers (follow-up 6e24 months) PhA decreased by 14 %e 17 % after RYGB [35e38,42], and in three papers by 11 %e19 % after LSG [35,37,38], whereas two papers (follow-up of 12 weeks and 12 months, respectively) found that PhA did not significantly change after RYGB or LSG [32,34]. The greatest decrease in PhA values was observed in patients with the highest loss of body weight following RYGB or LSG either after 24 months [37] or after 6 months [35,36]. The study by Teixeira et al [42] was the only one that performed segmental BIA showing reduced PhA values for both whole-body, upper (À13 % right, À16 % left) and lower limbs (À17 % right À17 % left).…”

“…Of note, in six out of eight papers PhA decreased by 11e20 %, independently of the type of surgery (RYGB o LSG) [33,35e38,42]. In the absence of other measurements of muscle quality, there is no obvious explanation for this finding; one paper suggested a worsening of nutritional status [33] and another two an increased risk of developing malnutrition [35,36], with no comments in the others.…”

Background & aims: Bioimpedance analysis-derived phase angle (PhA), as marker of body cell mass and cell integrity, might be altered in obesity, a condition which is characterized by alterations in muscle structure and function. The aim of this systematic review was to evaluate whether and to which extent PhA varies in individuals/ patients with excess body weight focusing on: a) changes in PhA due to obesity; b) changes in PhA after bariatric interventions or training programs. Methods: According to PRISMA criteria, a systematic literature search until February 2021 using PubMed, Embase, Scopus, and Web of Science was performed. Selection criteria included studies on patients with obesity without comorbidities other than metabolic diseases. Results: A total of 278 articles were first identified. After removing duplicates and excluding studies that did not fulfil the inclusion criteria, the full text of the remaining 80 potentially relevant studies was examined to finally retrieve 11 cross-sectional and 10 longitudinal studies. Few studies have shown that PhA is lower in individuals/patients with obesity than in controls. The only study on the matter showed a decrease with age after the fourth decade of life. Four out of five studies reported consistently greater mean values in men than in women. In two studies PhA was lower in patients with severe obesity; in addition, Patients with low PhA had higher BMI and PhA was inversely correlated with fat mass. Longitudinal studies showed that PhA markedly decreased after bariatric surgery and slightly increased after training programs. Conclusions: Thus, a relatively low number of studies have evaluated PhA in individuals/patients with obesity with sometimes contradictory and preliminary results. PhA might be useful to evaluate muscle quality in individuals/patients with obesity but further studies are needed to more accurately associate this variable with changes in muscle structure and strength, as well as in metabolic functions.

“…In a recent review, DiVincenzo O et al [ 38 ] found 8 eligible papers (4 with LSG, 2 RYGB and 1 LGB) comparing values before and from 6 weeks to 2 years after surgery and recovery [ 84 – 91 ]. The greatest decrease in PhA values was observed in patients with the highest loss of body weight following RYGB or LSG either after 24 months [ 89 ] or after 6 months [ 87 , 88 ]. Teixeira et al [ 91 ] reported that the decline of PhA after RYGB was negatively associated with weight loss and positively with the decrease of BMI, skeletal muscle mass, FM, and visceral fat area.…”

Phase angle (PhA) in overweight and obesity: evidence of applicability from diagnosis to weight changes in obesity treatment

Phase angle (PhA) is a recently proposed marker of nutritional status in many clinical conditions. Its use in patients with obesity presents different critical concerns due to the higher variability of the two measured parameters (resistance, R, and reactance, Xc) that contribute to the determination of PhA. Controversial is the relation between PhA and BMI that might vary with graded levels of obesity due to the variation in fat and free fat mass. Obesity is frequently associated with metabolic, hepatic, cardiovascular and kidney diseases that introduce variations in PhA values, in relation to multimorbidity and severity degree of these diseases. It is reported that the improvement of clinical condition is associated with a positive change in PhA. Also, the treatment of obesity with weight loss might confirm this effect, but with different responses in relation to the type and duration of the intervention applied. In fact, the effect appears not only related to the percentage of weight loss but also the possible loss of free fat mass and the nutritional, metabolic and structural modifications that might follow each therapeutic approach to decrease body weight. We can conclude that the PhA could be used as marker of health status in patients with obesity supporting an appropriate weight loss intervention to monitor efficacy and fat free mass preservation.

Variations in phase angle and handgrip strength in patients undergoing cardiac surgery: Prospective cohort study

et al. 2023

View full text Add to dashboard Cite

BackgroundBioimpedance phase angle (PA) is a measure of cell membrane integrity, whereas handgrip strength (HGS) is an evaluation of functional capacity. Although both are related to the prognosis of patients undergoing cardiac surgery, their changes over time are less known. This study followed variations in PA and HGS for 1 year in these patients, determining associations with clinical outcomes.MethodsThis prospective cohort study included 272 cardiac surgery patients. PA and HGS were measured at six predetermined times. The evaluated outcomes were surgery type; bleeding; time of surgery, cardiopulmonary bypass, aortic cross‐clamp, and mechanical ventilation; postoperative (PO) length of stay (LOS) in the intensive care unit (ICU) and hospital; and infections, hospital readmission, reoperation, and mortality.ResultsThere were reductions in PA and HGS values after surgery, with total recovery beginning at 6 months for PA and 3 months for HGS. In the PA area under the curve (AUC), age, combined surgery, and sex (β = −9.66, P < 0.001; β = −252.85, P = 0.005; β = −216.56, P < 0.001, respectively) were predictors for PA‐AUC reduction. Stratified by sex, age (β = −93.54, P < 0.001) and PO LOS (β = −46.91, P = 0.003) were predictors for HGS‐AUC reduction in women, but only age was a predictor in men (β = −77.02, P = 0.010). PA and HGS had an effect in hospital LOS and ICU LOS.ConclusionAge, combined surgery, and female sex were predictors of reduced PA‐AUC, whereas reduced HGS‐AUC was predicted by age in both sexes and PO hospital LOS in women, which suggests that these factors could interfere in prognosis.
