RESUMO

Edible insects are recognized as promising food sources due to their nutritional composition. Some species, such as Gryllus assimilis, contain proteins, lipids, and carbohydrates of high biological value, which regulate several metabolic functions, including the Renin-Angiotensin System (RAS). In this context, the present study aimed to assess the effects of dietary supplementation with whole Gryllus assimilis powder on the metabolism of malnourished mice. Thirty-two male Swiss mice were used and divided into four treatment groups. The groups were identified as (AIN93-M); AIN93-M + Gryllus assimilis diet (AIN93-M + GA); AIN93-M + Renutrition diet (AIN93-M + REN) and AIN93-M + Renutrition diet + Gryllus assimilis (AIN93-M + REN + GA). The results showed that whole Gryllus assimilis powder inclusion promotes recovery from protein-energy malnutrition, reduces adiposity, and improves glucose tolerance and insulin sensitivity. It also reduces total cholesterol, triglycerides, VLDL, and adipocyte area. We also observed a significant increase in the expression of RAS-related genes, such as ACE2 and MasR, followed by a reduction in Angiotensinogen and ACE. The main findings of the present study suggest the use of black cricket as a viable strategy for the prevention and treatment of protein-energy malnutrition, as well as the reduction of adiposity, and improvement of lipid and glycemic parameters, with antihypertensive potential.

RESUMO

INTRODUCTION: The French day hospital program specialized in eating disorders (ED) opened in January 2018. Our study presents preliminary data on clinical profiles of patients with anorexia nervosa (AN). We describe more specifically clinical characteristics of patients with early onset AN and according to their therapeutics orientations. Then, we compare the weight gain of patients managed only in day-patient (DP) treatment with those managed initially inpatient (IP) treatment and relays in DP. METHODS: Ninety-two patients with AN, aged between 8 and 18 years, were evaluated with several questionnaires (EDI-2, EDE-Q, BSQ, EDS-R, CDI, STAI-Y, VSP-A, EPN-13). RESULTS: Patients with early onset AN, n = 23 (25.3%), presented more restrictive behaviors, less marked dietary symptomatology, a lower degree of clinical perfectionism and a less marked feeling of ineffectiveness than adolescent patients with AN. Regarding the choice of hospitalization modality (DP alone or IP-DP), the only difference highlighted was the severity of patient undernutrition. Among the patients who were treated (IP-DP n = 27 vs DP alone n = 25), the weight evolution after one month and at discharge was favorable for both groups. CONCLUSION: These preliminary data suggest the effectiveness of DP in the care of AN in children and adolescents.

RESUMO

Introduction: Depression and anxiety are well-known comorbid conditions in patients with anorexia nervosa (AN). Hypercortisolemia in patients with AN may be pathogenic and contribute to depression and anxiety symptomatology. Objective: The aim of this study was to investigate short-term changes in cortisol levels and depression and anxiety symptomatology following intensive re-nutrition in patients with severe AN and hospitalized in a specialized unit. Furthermore, we investigated the potential association between cortisol levels and psychometric parameters. Methods: A total of 36 patients with AN were enrolled in the study. Nine dropped out before follow-up. Patients underwent paraclinical and psychometric examinations at admission and discharge. Measurements included plasma cortisol, cortisol binding globulin (CBG), 24-h urine cortisol, and self-report questionnaires regarding eating disorder, depression, anxiety, and stress symptoms. Patients were hospitalized in the unit for somatic stabilization and intensive re-nutrition. Mean admission length was 41 days. The study was registered at ClinicalTrials.gov (NCT02502617). Results: Cortisol levels in blood and urine did not change from admission to discharge in patients with severe AN. Symptoms of depression, anxiety, stress, and eating disorder remained elevated at discharge. There were no associations between changes in cortisol levels and changes in psychometrics. Discussion: Our results suggest that short-term intensive re-nutrition did not alter hypothalamic-pituitary-adrenal axis activity or mental health in patients with severe AN. Long-term stabilization and longer follow-up after hospital discharge may be needed to detect changes in cortisol levels and whether these changes are associated with depression and anxiety symptomatology. Greater knowledge about cortisol levels and mental health in patients with severe AN may help in the development of new treatment choices for the chronically ill patients. Future studies could investigate whether cortisol-lowering drugs have a therapeutic effect on mental health in AN.

RESUMO

Refeeding Syndrome: Where Do We Stand in 2022? Abstract. The refeeding syndrome is a potentially life-threatening condition that can occur when refeeding malnourished patients. In recent years, two consensus manuscripts were published by the major clinical nutrition societies ESPEN and ASPEN. Pathophysiological aspects, clinical manifestations, prevention measures and criteria for diagnosis and management have been described in detail. The aim of this mini-review is to provide an evidence-based overview on the refeeding syndrome. For this purpose, the systematic literature search by Friedli et al. 2015 was updated. Evidence that the refeeding syndrome is associated with a negative clinical outcome exists. Many questions about management aspects remain unanswered. A robust randomized controlled trial is urgently needed to answer all these questions in an evidence-based manner and to elicit reliable evidence about independent predictors and an estimate of metabolic risk.

RESUMO

Covid-19 infection is a potentially serious disease. Overweight, obesity, and diabetes are comorbidities frequently found in the severe form of the disease. Appropriate nutritional management of the patient is an integral part of care. We will discuss the renutrition of a 76-year-old, obese (BMI = 35kg/m2), malnourished patient, according to the 2021 Haute Autorité de santé criteria, with Covid-19 infection, admitted to the intensive care unit at the Bordeaux University Hospital for an acute respiratory distress syndrome. Adaptation of nutritional intakes was achieved by clinical and biological monitoring. A refeeding syndrome was treated on the first day of hospitalization in the intensive care unit. After thiamine supplementation and when kalemia and phosphatemia have been normalized, renutrition was started. Parenteral nutrition as a complement to oral nutrition was used. Parenteral nutrition was well tolerated; recommended caloric and protein intakes were achieved by the fourth day of hospitalization. The clinical evolution was favorable. In conclusion, patients with Covid-19 infection should be considered malnourished when admitted to the intensive care unit. Macro and micronutrient intakes adapted to metabolically stressed patients are essential. Biological monitoring including monitoring of ionogram, phosphate, uremia, creatinine, liver function tests and blood glucose is essential in the nutritional management of patients with serious Covid-19 infection.

RESUMO

Refeeding syndrome (RS) is a rare but severe condition that is poorly understood, often under-diagnosed and can lead to death. It occurs within 5 days after refeeding in patients after prolonged fasting or in a context of undernutrition. As a consequence of the abrupt transition from catabolism to anabolism, RS is defined as a decrease in plasma levels of phosphorus, potassium and/or magnesium, whether or not associated with organ dysfunction resulting from a decrease in one of the electrolytes or a thiamine deficiency, after refeeding. The clinical symptoms are varied and non-specific and are related to hydro electrolyte disorders, sodium-hydroxide retention or failure of one or more organs. Patient management should be appropriate with regular clinical examination and careful biological monitoring, including hydro electrolyte monitoring. The correction of hydroelectrolytic disorders and systematic thiamine supplementation are essential during refeeding, that must be done carefully and very progressively, whatever its form (oral, enteral or parenteral). The severity of the refeeding syndrome indicates that its prevention and screening are the corners of its management in at-risk patients.

RESUMO

OBJECTIVE: Nutrition restoration in inpatients with anorexia nervosa (AN) is a core element in treatment, enabling recovery of cognitive functions essential for psychological care. This study aims to identify factors associated with inpatient weight gain. METHODS: Medical records from 107 inpatients aged 13-55 years with AN, hospitalized for more than 7 days at a specialized unit, were examined in a retrospective study. Weight evolution graphs were created for each patient and graded independently as optimal, moderate, and inadequate weight gain after 2 weeks and increasing, flat or decreasing weight in the first 2 weeks by expert clinicians. Driven by explicit hypotheses, bivariable analyses were carried out to detect relevant factors associated with weight gain during and after the first 2 weeks of admission. RESULTS: Initial weight gain in the first 2 weeks of hospitalization and the introduction of a protocol harmonizing treatment procedures around rapid refeeding were strong factors associated with optimal weight gain after 2 weeks of hospitalization, whereas prior hospitalization in a psychiatric unit, diagnosis with binge-eating/purging subtype and age over 18 years were significantly associated with inadequate weight gain (p < 0.001-0.05). CONCLUSION: To promote weight gain during hospitalization, clinicians should consider the following therapeutic measures: rapid refeeding strategies, renutrition protocols, and controlling purging behaviors. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

RESUMO

OBJECTIVE: Alterations in blood lipid concentrations in anorexia nervosa (AN) have been reported; however, the extent, mechanism, and normalization with weight restoration remain unknown. We conducted a systematic review and a meta-analysis to evaluate changes in lipid concentrations in acutely-ill AN patients compared with healthy controls (HC) and to examine the effect of partial weight restoration. METHOD: A systematic literature review and meta-analysis (PROSPERO: CRD42017078014) were conducted for original peer-reviewed articles. RESULTS: Forty-eight studies were eligible for review; 33 for meta-analyses calculating mean differences (MD). Total cholesterol (MD = 22.7 mg/dL, 95% CI = 12.5, 33.0), high-density lipoprotein (HDL; MD = 3.4 mg/dL, CI = 0.3, 7.0), low-density lipoprotein (LDL; MD = 12.2 mg/dL, CI = 4.4, 20.1), triglycerides (TG; MD = 8.1 mg/dL, CI = 1.7, 14.5), and apolipoprotein B (Apo B; MD = 11.8 mg/dL, CI = 2.3, 21.2) were significantly higher in acutely-ill AN than HC. Partially weight-restored AN patients had higher total cholesterol (MD = 14.8 mg/dL, CI = 2.1, 27.5) and LDL (MD = 16.1 mg/dL, CI = 2.3, 30.0). Pre- versus post-weight restoration differences in lipid concentrations did not differ significantly. DISCUSSION: We report aggregate evidence for elevated lipid concentrations in acutely-ill AN patients compared with HC, some of which persist after partial weight restoration. This could signal an underlying adaptation or dysregulation not fully reversed by weight restoration. Although concentrations differed between AN and HC, most lipid concentrations remained within the reference range and meta-analyses were limited by the number of available studies.


OBJETIVO: En la anorexia nervosa (AN) han sido reportadas alteraciones en las concentraciones de lípidos sanguíneos; sin embargo, la extensión, mecanismo y normalización con la restauración del peso continúa aún desconocida. Hicimos una revisión sistemática y meta-análisis para evaluar los cambios en las concentraciones de lípidos en pacientes agudamente enfermas de AN comparados con controles sanos (HC) y para examinar el efecto parcial de la restauración de peso. MÉTODO: Una revisión sistemática de la literatura y meta-análisis (PROSPERO: CRD42017078014) fueron llevados a cabo en artículos originales revisados por pares. RESULTADOS: Un total de cuarenta y ocho estudios fueron elegibles para revisión; 33 para meta-análisis calculando las diferencias promedio (MD). Colesterol total (MD = 22.7 mg/dL, 95% CI = 12.5, 33.0), lipoproteína de alta densidad (HDL; MD = 3.4 mg/dL, CI = 0.3, 7.0), lipoproteína de baja densidad (LDL; MD = 12.2 mg/dL, CI = 4.4, 20.1), triglicéridos (TG; MD = 8.1 mg/dL, CI = 1.7, 14.5), y apolipoproteína B (Apo B; MD = 11.6 mg/dL, CI = 2.3, 21.2) fueron significativamente elevados en los pacientes agudamente enfermos de AN en comparación con los controles sanos (HC). Los pacientes con AN parcialmente recuperados de peso tuvieron niveles más elevados de colesterol total (MD = 14.8 mg/dL, CI = 2.1, 27.5) y de LDL (MD = 16.1 mg/dL, CI = 2.3, 30.0). Las diferencias pre- versus post- restauración de peso en las concentraciones de lípidos no difirieron significativamente. DISCUSIÓN: Reportamos evidencia agregada de concentraciones elevadas de lípidos en pacientes agudamente enfermos de AN comparados con controles sanos (HC), algunos de los cuales persisten después de la restauración parcial de peso. Esto podría señalar una adaptación subyacente o desregulación no completamente revertida por la restauración del peso. Aunque las concentraciones difirieron entre AN y HC, la mayoría de las concentraciones de lípidos permanecieron dentro del rango de referencia y los meta-análisis fueron limitados por el número de estudios disponibles.

RESUMO

Protein energy wasting (PEW) is an independent factor associated with morbi-mortality in chronic kidney disease. Wasting is particularly common in chronic diseases of organs such as kidney disease with a major impact at the stage of dialysis. It covers 20 to 70% of patients diagnosed with chronic kidney disease according to the degree of evolution of the disease and the diagnostic method used patients. Mechanisms of PEW are based mainly on anorexia and metabolic abnormalities caused by kidney disease. Nutritional treatment differs depending on the stage of the kidney disease acute or chronic treated whether or not by dialysis. Nutritional monitoring should be regular, individualized and collaborative to detect a risk of PEW or treat installed PEW. Refeeding techniques should allow all the nutritional needs. Their indications depend on the clinic, biochemical assessment and nutrient intake.

RESUMO

BACKGROUND & AIMS: Patients with anorexia nervosa (AN) have low serum IGF-I levels that may contribute to a lower bone mineral mass. We investigated the effects of a fermented, protein-fortified, dairy product on serum IGF-I levels in patients with AN during an in-hospital refeeding program. METHODS: In this multicenter, randomized, double-blind, placebo-controlled, clinical trial conducted at 3 university hospitals and 3 private clinics in France and Switzerland, 62 women recently admitted with confirmed AN and with a baseline low serum IGF-I level were randomized to 2 daily isocaloric fresh cheese pots containing either 15 g/150 g or 3 g/150 g (controls) of protein for 4 weeks. The primary outcome was the change in IGF-I levels. RESULTS: In the primary intention-to-treat analysis, mean serum IGF-I levels increased during the intervention phase from 22.9 ± 1.5 to 28.6 ± 1.3 nmol/L (means ± SEM) (+20.2%) in the intervention group and from 20.2 ± 1.2 to 25.7 ± 1.5 nmol/L (+16.8%) in controls. In a preplanned analysis of covariance with repeated measures, the between-group difference was close to statistical significance (P = 0.071). In a post-hoc mixed-regression model analysis, the difference was statistically significant (4.9 nmol/l increase; P = 0.003), as was the change of the ratio IGF-I/IGF-BP3 (P=0.004). There was no between-group difference in biochemical markers of bone turnover (osteocalcin, P1NP, CTX) or in serum parathyroid hormone level. Serum calcium levels slightly increased during the intervention phase in the higher protein group (P = 0.02). IGF-BP2 decreased significantly more in the intervention group during the follow up period at week 4 after supplements cessation (P = 0.019). CONCLUSIONS: Intake of a fermented, protein-fortified, isocaloric dairy product during 4 weeks may slightly increase serum IGF-I levels in women with AN, without significant changes in bone turnover markers. CLINICAL TRIAL REGISTRATION NUMBER: NCT01823822 (www.clinicaltrials.gov).

RESUMO

Anorexia is a complex, multifactorial disease, emerging during puberty and requiring cross-disciplinary care. The body, taken hostage, expresses psychological suffering and the patient's developmental impasse. Compassionate treatment and the care given to this mistreated and undernourished body facilitate the access to the psychological care and are an essential step towards recovery.

RESUMO

UNLABELLED: Malnutrition is an independent factor associated with morbi-mortality in chronic kidney disease. It is particularly common and may increase during hospitalization. OBJECTIVES: To measure nutritional and physical performance evolution as well as patients' physical autonomy during a hospitalization in a university hospital renal ward. Treatments were adjusted according to different diagnoses (nutritional care, body composition, physical activity) along with a multidisciplinary approach. In this way, it can show the impact of this care on nutritional status of the patient. DESIGN: Regardless of their nutritional status and kidney disease (acute or chronic kidney disease, chronic hemodialysis), patients were included at day 0, within 2 days from admission; nutritional interventions and measurements were assessed on day 7, day 14 and day 21. The study was run from December 2011 till June 2012, and 48 patients were included. RESULTS: On admission, patients had a low energy intake (20.9±8.6 kcal/kg/day). This intake was improved by means of a dietetic intervention (28.1±6.5 kcal/kg/day after two weeks of hospitalization, 29±6.1 kcal/kg/day after three weeks and 29±8.4 kcal/kg/day after four weeks). Seventy-three percent of the hospitalized patients were malnourished, among them 91% had a decreased serum albumin (26.8±6.6 g/L). Weight and muscle mass (measured by impedancemetry) were maintained, prealbumin increased by 16.5 mg/L after two weeks (n=48; P=0.61), 27.8 mg/L after three weeks (n=31; P=0.018), 52.3 mg/L after four weeks (n=13; P=0.002) and albuminemia by 1.8 g/L (n=13 patients monitoring four weeks; P=0.13). Both physical autonomy (assessed with Test moteur minimum) and muscle strength (Hand Grip Test) were significantly improved. CONCLUSION: A systematic screening of wasting and a multidisciplinary care improved nutritional status and physical ability of patients hospitalized in a renal ward.

RESUMO

Aging leads to increased insulin resistance and arterial dysfunction, with oxidative stress playing an important role. This study explored the metabolic and arterial effects of a chronic treatment with resveratrol, an antioxidant polyphenol compound that has been shown to restore insulin sensitivity and decrease oxidative stress, in old mice with or without a high-protein diet renutrition care. High-protein diet tended to increase insulin resistance and atheromatous risk. Resveratrol improved insulin sensitivity in old mice fed standard diet by decreasing homeostasis model of assessment-insulin resistance and resistin levels. However, resveratrol did not improve insulin resistance status in old mice receiving the high-protein diet. In contrast, resveratrol exhibited deleterious effects by increasing inflammation state and superoxide production and diminishing aortic distensibility. In conclusion, we demonstrate that resveratrol has beneficial or deleterious effects on insulin sensitivity and arterial function, depending on nutritional status in our models.
