Association between fat-free mass and survival in critically ill patients with COVID-19:A prospective cohort study

Background: Most critically ill patients with COVID-19 experience malnutrition and weight loss associated with negative clinical outcomes. Our primary aim was to assess body composition during acute and late phase of illness in these patients in relation to clinical outcome and secondary to tailored nutrition support. Methods: This prospective cohort study included adult critically ill patients with COVID-19. Body composition (fat-free mass [FFM] [exposure of interest], fat mass [FM], skeletal muscle mass [SMM], and phase angle [PA]) was determined with multifrequency bioelectrical impedance analyses in the acute and late phase. Nutrition support data were collected simultaneously. Clinical outcome was defined as intensive care unit (ICU) survival (primary outcome) and 30–90 days thereafter, duration of mechanical ventilation, and length of ICU stay and length of hospital stay (LOS). Nonparametric tests and regression analyses were performed. Results: We included 70 patients (73% male, median age 60 years). Upon admission, median BMI was 30 kg/m 2, 54% had obesity (BMI &gt; 30 kg/m 2). Median weight change during ICU stay was −3 kg: +3 kg FM and −6 kg FFM (−4 kg SMM). Body composition changed significantly (P &lt; 0.001). Regarding clinical outcome, only low PA was associated with prolonged LOS (odds ratio = 0.83, 95% CI = 0.72–0.96; P = 0.015). Patients with optimal protein intake (&gt;80%) during acute phase maintained significantly more FFM (2.7 kg, P = 0.047) in the late phase compared with patients who received &lt;80%. Conclusion: FFM decreased significantly during acute and late phase of illness, but we observed no association with ICU survival. Only low PA was associated with prolonged LOS. FFM wasting likely occurred because of disease severity and immobility.</p

Effects of correcting metabolic acidosis on muscle mass and functionality in chronic kidney disease:a systematic review and meta-analysis

Metabolic acidosis unfavourably influences the nutritional status of patients with non-dialysis dependent chronic kidney disease (CKD) including the loss of muscle mass and functionality, but the benefits of correction are uncertain. We investigated the effects of correcting metabolic acidosis on nutritional status in patients with CKD in a systematic review and meta-analysis. A search was conducted in MEDLINE and the Cochrane Library from inception to June 2023. Study selection, bias assessment, and data extraction were independently performed by two reviewers. The Cochrane risk of bias tool was used to assess the quality of individual studies. We applied random effects meta-analysis to obtain pooled standardized mean difference (SMD) and 95% confidence intervals (CIs). We retrieved data from 12 intervention studies including 1995 patients, with a mean age of 63.7 ± 11.7 years, a mean estimated glomerular filtration rate of 29.8 ± 8.8 mL/min per 1.73 m2, and 58% were male. Eleven studies performed an intervention with oral sodium bicarbonate compared with either placebo or with standard care and one study compared veverimer, an oral HCl-binding polymer, with placebo. The mean change in serum bicarbonate was +3.6 mEq/L in the intervention group and +0.4 mEq/L in the control group. Correcting metabolic acidosis significantly improved muscle mass assessed by mid-arm muscle circumference (SMD 0.35 [95% CI 0.16 to 0.54], P &lt; 0.001) and functionality assessed with the sit-to-stand test (SMD −0.31 [95% CI −0.52 to 0.11], P = 0.003). We found no statistically significant effects on dietary protein intake, handgrip strength, serum albumin and prealbumin concentrations, and blood urea nitrogen. Correcting metabolic acidosis in patients with CKD improves muscle mass and physical function. Correction of metabolic acidosis should be considered as part of the nutritional care for patients with CKD.</p

Impact of infantile short bowel syndrome on long-term health-related quality of life: a cross-sectional study

Studies on the long-term effects of short bowel syndrome (SBS) on the quality of life are scarce. Therefore, we determined health-related quality of life (HRQoL) in children and adolescents with a history of infantile SBS compared with that of same-aged controls drawn from the general population. Cross-sectional assessment (2005-2007) of HRQoL in children with a history of infantile SBS treated in their first year of life, born between 1987 and 2002, using generic HRQoL measures was performed. Children aged 5 to 18 years and their parents filled out the Pediatric Quality of Life Inventory. Differences in scores between subjects and controls were analyzed using independent sample t tests. Thirty-one children with a history of SBS (19 girls and 12 boys; mean age, 11.8 ± 4.2 years) participated, giving an overall response rate of 70%. The children and their parents reported significantly lower HRQoL than 275 healthy age-matched children and their parents (P <.05). Children with a history of infantile SBS have a lower HRQoL than healthy age-matched controls. This difference lasts beyond childhood and way beyond the period of intestinal rehabilitation early in life. These findings highlight the need for targeted interventions to address these dimensions of impaired HRQo

Fish oil in prolonged parenteral nutrition in children:omega-3-fatty acids have a beneficial effect on the liver

Neonates with intestinal failure are dependent on total parenteral nutrition (TPN) and therefore at risk for developing parenteral nutrition associated liver disease (PNALD). In this clinical lesson we report the treatment of PNALD in 3 infants with short bowel syndrome. Conventional omega-6 fat emulsion was substituted by omega-3 fish oil as the sole source of fat in TPN. The described patients were diagnosed as having multiple intestinal atresias, necrotizing enterocolitis and midgut volvulus, respectively, and all patients suffered from short bowel syndrome and were TPN-dependent. When persistent or progressive cholestasis occurred, omega-6 fat emulsion was replaced by omega-3 fish oil. In all 3 cases complete reversal of cholestasis was seen within months after the fish oil-fat emulsion switch. No negative side-effects were reported. These first experiences with the use of fish oil in children in the Netherlands confirm earlier suggested beneficial effects of omega-3 fatty acids in the treatment of PNALD in children with short bowel syndrome.</p

Nutritional status of patients with COVID-19 1-y post-ICU stay: A prospective observational study

Objectives: Patients discharged from the intensive care unit (ICU) often experience physical complaints and poor nutritional intake, which negatively affect their nutritional status (NS). The aim of this study was to describe the NS of patients with COVID-19 1-y post-ICU stay. Methods: This was an observational study of adult patients with COVID-19 1-y post-ICU stay. NS assessment (nutrient balance, body composition, and physical status) was performed. We examined nutritional intake and nutrition-related complaints. Nutritional requirements were determined with indirect calorimetry and body composition with bioelectrical impedance. Fat-free mass index (FFMI) and fat mass index (FMI) were calculated. Physical status was determined using handgrip strength, the 6-min walk test, and the 1-min sit-to-stand test. Descriptive statistics and paired sample t tests were used for analysis. Results: We included 48 patients (73% men; median age 60 y [IQR 52;65]). Median weight loss during the ICU stay was 13%. One-y post-ICU stay, 12% of weight was regained. Median body mass index was 26 kg/m2 and 23% of the patients were obese (body mass index >30 kg/m2 and high FMI). Of the patients, 50% had high FMI and 19% had low FFMI. Median reported nutritional intake was 90% of measured resting energy expenditure. Nutrition-related complaints were seen in 16%. Percentages of normal values reached in physical tests were 92% of handgrip strength, 95% of 6-min walking distance, and 79% of 1-min sit-to-stand test. Conclusions: Despite almost fully regained weight and good physical recovery in adult patients 1-y post-ICU stay, NS remained impaired because of elevated FMI, even though reported nutritional intake was below the estimated requirements

Health-related quality of life, anxiety, depression and distress of mothers and fathers of children on Home parenteral nutrition

Background & aims: Parents of children with intestinal failure, dependent on Home Parenteral Nutrition (HPN), may experience psychosocial problems due to the illness and intensive treatment of their child. Literature concerning psychosocial problems is scarce. Therefore, we aimed to investigate Health-Related Quality of Life (HRQOL), levels of anxiety, depression, distress and everyday problems of these mothers and fathers. Methods: A multicenter study was conducted among 37 mothers and 25 fathers of 37 children on HPN (response-rate 37/49 = 76%, mean age children = 5.1 years, SD = 4.6). Parents completed three questionnaires to measure different outcomes on the KLIK website (www.hetklikt.nu): the TNO-AZL QOL Questionnaire (TAAQOL) to measure HRQOL, the Hospital Anxiety and Depression Scale (HADS) to measure anxiety and depression, and the Distress Thermometer for Parents (DT-P) to measure distress. Scores were compared to Dutch reference mothers and fathers using Mann–Whitney U-tests. Results: No differences were found in HRQOL, measured by the TAAQOL, between HPN parents compared to the reference groups, except for the subscale ‘depressive emotions’ for mothers (p =.01) and ‘daily activities’ for fathers (p =.04). HPN mothers reported higher levels of depression compared to reference mothers (p =.001). In addition, HPN mothers and fathers reported higher levels of distress than reference mothers (p =.001) and fathers (p =.03). HPN mothers reported significantly more problems in the practical, emotional, cognitive and parenting domains, fathers in the social, emotional and parenting domains. Conclusions: On HRQOL, anxiety and depression, HPN parents generally did not show much differences compared to reference parents. However, when asked about parental distress and everyday problems, HPN treatment of their child seems highly stressful for some parents and influences daily functioning. Therefore, structural screening for parental psychosocial problems in clinical practice, e.g. using the DT-P, is necessary in order to improve the well-being of both these parents and their children dependent on HPN

Intestinal rehabilitation for children with intestinal failure is cost-effective:a simulation study

Background: Children with intestinal failure (IF) depend on parenteral nutrition (PN). The goal in the treatment of IF is to wean children off PN through intestinal rehabilitation (IR). Although the healthcare burden of IF is enormous, to our knowledge there has been no previous cost-effectiveness analysis in pediatric IF including IR. Objective: We sought to determine the cost-effectiveness of IR in terms of costs and life-years. Design: We simulated the treatment of IF in children in a discrete-event model. Data for this model were derived from patient records, the Dutch Registry of Intestinal Failure and Transplantation, the Intestinal Transplant Registry, and the literature. The time horizon of the model was 40 y. Simulated patients were enrolled at a rate of 40 patients/mo for 10 y. Actual costs were calculated for hospital admissions, surgical interventions, endoscopies, PN, and immunosuppressive medication. We evaluated the cost-effectiveness of IR by comparing 1 scenario with IR with 1 scenario without IR. In the scenario with IR, a proportion of patients who represented those with the ability to wean off PN were assigned to IR. In the scenario without IR, all patients progressed to. home PN (HPN). In both scenarios, a proportion of patients receiving HPN were eventually eligible for an intestinal transplantation. Results: IR prolonged survival; the mean number of life-years per patient was 19.4 in the scenario with IR compared with 18.2 in the scenario without IR. Average total costs per patient were 819,292 in the scenario with IR compared with 1,176,830 in the scenario without IR (equivalent to 1,129,230 US$and 1,622,025 US$, respectively, in January 2014); costs mainly included hospital admissions and PN. Conclusions: On the basis of our simulations, we concluded that IR improved the survival of children with IF and was associated with cost savings. Therefore, we consider IR to be a cost-effective treatment for children with IF
