Correlation between SARC-F Score and Ultrasound-Measured Thigh Muscle Thickness in Older Hospitalized Cancer Patients.

BACKGROUND: Strength, Assistance for walking, Rise from a chair, Climb stairs, and Falls (SARC-F) score is frequently used for screening the sarcopenia risk in older people. However, the agreement between SARC-F and loss of ultrasound-derived muscle thickness in hospitalized older cancer patients is unexplored. OBJECTIVE: The primary objective was to evaluate the relationship between the SARC-F score and ultrasound-derived muscle thickness of rectus femoris and vastus intermedius in older hospitalised cancer patients. The secondary objective was to identify the presence of sarcopenia. MEASUREMENTS: A cross-sectional study enrolled forty-one older hospitalised cancer patients ongoing chemotherapy or surgical treatment. Body weight (kg) was measured using a digital scale and height using a portable stadiometer to assess body mass index. SARC-F was performed to assess and classify sarcopenia risk (with (SARC-F: ≥4), without (SARC-F: <4). US-derived muscle thickness of rectus femoris and vastus intermedius was assessed using a portable ultrasound. Relationship between the SARC-F and muscle thickness was tested using Pearson´s correlation and Bland-Altman analyses. RESULTS: Approximately, 46.3% of the patients presented sarcopenia and a lower non-significant muscle thickness of rectus femoris and vastus intermedius (SARC-F ≥4: 18.54±6.28 vs. SARC-F <4: 22.22±9.16 mm, p=0.07). There was a moderate negative correlation between SARC-F and muscle thickness (r=-0.40, p=0.004). Additionally, Bland-Altman plots no found systematic bias risk between SARC-F and ultrasound-derived muscle thickness. CONCLUSIONS: Approximately, 46.3% of older hospitalized cancer patients presented sarcopenia. Additionally, we found a moderate inverse correlation and no systematic bias risk between SARC-F and ultrasound-measured muscle thickness.

Health benefits and consequences of the Eastern Orthodox fasting in monks of Mount Athos: a cross-sectional study.

BACKGROUND/OBJECTIVES: Greek Orthodox fasting (OF), which involves 180-200 days of fasting per year, is dictated by the Christian Orthodox religion. For the first time, this cross-sectional study examines the characteristics and the effects of OF on anthropometry, cardiometabolic markers and calcium homeostasis in Athonian monks (AMs). SUBJECTS/METHODS: Daily intakes of energy, macro- and micronutrients of a day during a weekend of Nativity Fast, defined as non-restrictive day (NRD), and a weekday during Great Lent, labeled as restrictive day (RD) were recorded. RESULTS: The daily energy intake of 70 AM (age=38.8±9.7 years) was low during both RD and NRD (1265.9±84.5 vs 1660±81 kcal, respectively, P<0.001). Paired samples t-test showed statistically significant difference between daily intakes in RD and NRD: carbohydrates (159.6±21.8 vs 294.3±23.4 g, P<0.0001) and saturated fat (12.7±0.0 vs 16.4±0.0 g, P<0.0001) were lower, whereas protein (89.2±1.3 vs 72.35±1.3 g, P<0.001) was higher during RD. A subsample of 50 monks (age=38.7±10.6 years) formed a study cohort for cardiometabolic and calcium homeostasis assessment. Body weight (74.3±12.9 kg) and body mass index (BMI; 23.8±4.1 kg/m2) were independent of level of physical activity. Optimal profiles for lipid and glucose parameters (total cholesterol: 183.4±41.7 mg/dl, LDL: 120.6±37.6 mg/dl, triglycerides: 72.2±31.3 mg/dl, HDL: 48.5±14.2 mg/dl and homeostasis model assessment of insulin resistance (HOMA-IR) 1.02±0.40) were found. Profound hypovitaminosis D (8.8±6.2 ng/ml), high parathyroid hormone (PTH): 115.5±48.0 pg/ml with normal serum calcium levels (8.9±3.2 mg/dl) was observed. CONCLUSIONS: Unaffected by variation in lifestyle factors, the results of this unique study offers clear evidence for the health benefits of the strict Athonian OF through optimal lipid and glucose homeostasis.

Carbohydrates and insulin resistance in clinical nutrition: Recommendations from the ESPEN expert group.

Growing evidence underscores the important role of glycemic control in health and recovery from illness. Carbohydrate ingestion in the diet or administration in nutritional support is mandatory, but carbohydrate intake can adversely affect major body organs and tissues if resulting plasma glucose becomes too high, too low, or highly variable. Plasma glucose control is especially important for patients with conditions such as diabetes or metabolic stress resulting from critical illness or surgery. These patients are particularly in need of glycemic management to help lessen glycemic variability and its negative health consequences when nutritional support is administered. Here we report on recent findings and emerging trends in the field based on an ESPEN workshop held in Venice, Italy, 8-9 November 2015. Evidence was discussed on pathophysiology, clinical impact, and nutritional recommendations for carbohydrate utilization and management in nutritional support. The main conclusions were: a) excess glucose and fructose availability may exacerbate metabolic complications in skeletal muscle, adipose tissue, and liver and can result in negative clinical impact; b) low-glycemic index and high-fiber diets, including specialty products for nutritional support, may provide metabolic and clinical benefits in individuals with obesity, insulin resistance, and diabetes; c) in acute conditions such as surgery and critical illness, insulin resistance and elevated circulating glucose levels have a negative impact on patient outcomes and should be prevented through nutritional and/or pharmacological intervention. In such acute settings, efforts should be implemented towards defining optimal plasma glucose targets, avoiding excessive plasma glucose variability, and optimizing glucose control relative to nutritional support.

[Refeeding syndrome: practical issues]. / Syndrome de renutrition inappropriée: aspects pratiques.

The refeeding syndrome is frequent and potentially deadly, still it is underdiagnosed. It is defined by clinical and biological manifestations that are seen upon refeeding of malnourished patients. It is the consequence of the transition from catabolism to anabolism. Ions intracellular shift caused by insulin and B1 vitamin deficiency are fundamental in the development of this syndrome. Riskconditions are well summarized by the NICE criteria. To avoid refeeding syndrome, it is fundamental to find and correct any electrolytic deficiency and to give thiamine before starting a slow and progressive oral, enteral or parenteral refeeding.

Body composition during growth in children: limitations and perspectives of bioelectrical impedance analysis.

There are a number of differences between the body composition of children and adults. Body composition measurements in children are inherently challenging, because of the rapid growth-related changes in height, weight, fat-free mass (FFM) and fat mass (FM), but they are fundamental for the quality of the clinical follow-up. All body composition measurements for clinical use are 'indirect' methods based on assumptions that do not hold true in all situations or subjects. The clinician must primarily rely on two-compartment models (that is, FM and FFM) for routine determination of body composition of children. Bioelectrical impedance analysis (BIA) is promising as a bedside method, because of its low cost and ease of use. This paper gives an overview of the differences in body composition between adults and children in order to understand and appreciate the difference in body composition during growth. It further discusses the use and limitations of BIA/bioelectrical spectroscopy (BIA/BIS) in children. Single-frequency and multi-frequency BIA equations must be refined to better reflect the body composition of children of specific ethnicities and ages but will require development and cross-validation. In conclusion, recent studies suggest that BIA-derived body composition and phase angle measurements are valuable to assess nutritional status and growth in children, and may be useful to determine baseline measurements at hospital admission, and to monitor progress of nutrition treatment or change in nutritional status during hospitalization.

[Insulin therapy and parenteral nutrition in intensive care: practical aspects]. / Insulinothérapie et nutrition parentérale en soins intensifs: aspects pratiques.

Critically ill patients are hypercatabolic due to stress and inflammation. This condition induces hyperglycemia. Muscle wasting is intense during critical illness. Its prevention is essential. This is possible by early and appropriate nutritional support. Preserving the function of the gastrointestinal tract with enteral nutrition is the gold standard. However, when targeted protein-caloric intake is not met through enteral nutrition within the first three days in the intensive care unit (ICU), supplemental parenteral nutrition is administered to reduce morbidity and mortality. In addition, in order to limit metabolic imbalance and reduce mortality, glycemic control using insulin therapy is mandatory. This article reviews the current understanding of parenteral nutrition and insulin therapy in ICU patients, and provides the decision model applied in our institution.

Does perioperative nutrition and oral carbohydrate load sustainably preserve muscle mass after bariatric surgery? A randomized control trial.

BACKGROUND: Perioperative nutrition and preoperative oral carbohydrate loading (CHL) have a beneficial impact on the outcomes of gastrointestinal oncological surgery. However no data exists on their effect on morbidly obese patients. OBJECTIVES: Our aim was to establish the short-term and long-term impact of these modalities, notably on metabolically active lean body mass (LBM) - an important factor in maintaining long-term weight loss. METHODS: Patients undergoing laparoscopic Roux-en-Y gastric bypass were randomized to standard management or intervention: CHL drinks consumed 12 and 2 hours presurgery, and immediate postoperative peripheral parenteral nutrition. The primary outcome measured was LBM, measured by Bioelectrical Impedance Analysis (BIA), one and 12 months postsurgery. Secondary outcomes included excess weight loss (EBWL), 30-day complication rate, and length of stay. RESULTS: Of the 203 randomized patients, 198 were included in the analysis. All 101 patients in the control group completed the one-year follow up and 76 completed the BIA. In the intervention group, 93 of 97 patients completed the one-year follow-up and 71 completed the BIA. At one and 12 months follow-up, body composition, LBM, or EBWL were comparable. There was no difference in operative outcomes, complications rates, or length of stay. There was no adverse effect in the intervention group. CONCLUSIONS: In a highly homogeneous group of morbidly obese patients with one-year follow-up, CHL and short-term parenteral nutrition did not lead to significant or sustained LBM preservation or modification in EBWL. There was no significant decrease in complications or length of stay. Our study confirms the safety of these interventions, even in previously unstudied Type 2 diabetic patients.

[Prostate cancer and androgen deprivation: benefits of psychological counseling]. / Cancer de la prostate et déprivation androgénique: bénéfices d'un accompagnement psychologique.

Androgen deprivation is a therapeutic option for patients with prostate cancer, however with a range of side effects that negatively affects their physical and psychological condition. A multidisciplinary care program, ADAPP ("Androgenic deprivation in prostate cancer patients"), has been created with a special focus on managing these side effects. This article describes the intervention of the liaison psychiatry within this program, with care options ranging from psychological support to intensive psychotherapy to address patients' intrapsychic dynamics throughout this care program. Clinical cases are reported to illustrate the relevance and the necessity of this specialized counselling.

[Chronic obstructive pulmonary disease: risk and benefit of testosterone therapy]. / Bronchopneumopathie chronique obstructive: risques et bénéfices d'un traitement de testostérone.

Muscular wasting is frequently encountered in COPD patients and is related to a decrease in exercise tolerance, a higher morbidity and mortality. One of the potential causes isa low serum testosterone, which is frequent in COPD. Various studies have explored the effect of testosterone administration alone or as part of combined pulmonary rehabilitation and nutrition protocols. Testosterone had a positive impact on muscle mass and force, and to a lesser extent on physical endurance and respiratory parameters. Future studies should better define appropriate dosage and treatment duration. In the meantime, testosterone should be administered to COPD patients with overt hypogonadism, or in multidisciplinary specialized programmes.

[Enteral nutrition: nasogastric tube or percutaneous endoscopic gastrostomy?]. / Nutrition entérale: sonde nasogastrique ou gastrostomie percutanée endoscopique?

When enteral nutrition is indicated to prevent or to treat a patient with denutrition choosing between a nasogastric tube (NGT) and a percutaneous endoscopic gastrostomy (PEG) is not always an easy decision. In neurological patients with swallowing disturbances or in patients with head and neck tumors, PEG is associated with lower rates of feeding tube dislodgement, while NGT has lower rates or morbidity. A meta-analysis showed that the interruption of nutrition is less frequent with PEG but there is no difference in terms of mortality and aspiration pneumonia between PEG and NGT. The European Society for Clinical Nutrition and Metabolism recommends PEG when enteral nutrition is expected to last more than 3 weeks.

Can birth weight predict later body composition in anorexia nervosa?

BACKGROUND/OBJECTIVES: The relationship between birth weight and body composition at later stages in life was not studied previously in anorexia nervosa (AN). The aim of the following brief report is to present results concerning the relationship between birth weight and later body composition specifically in AN, and to check if the programming of body composition from birth weight is still detected in severely emaciated AN patients. SUBJECTS/METHODS: One hundred and fifty-one female AN patients aged between 13 and 44 were recruited from 11 inpatient treatment facilities in France. Birth weight, body weight and height were obtained. Body composition was measured using bioelectrical impedance. Birth weight was significantly correlated to lifetime maximum body mass index (BMI; r=0.211, P=0.009) and significantly correlated to fat-free mass index (r=0.190, P=0.027) but not to fat mass index (FMI). RESULTS: This report confirms that even in AN when patients are severely emaciated and where fat-free mass (FFM) and fat mass (FM) are low, a link between birth weight and FFM and BMI can still be identified, independently from age. CONCLUSION: Further studies are needed on larger samples exploring other factors, such as gender, puberty and ethnicity.

Protein catabolism and requirements in severe illness.

Reduced total body protein mass is a marker of protein-energy malnutrition and has been associated with numerous complications. Severe illness is characterized by a loss of total body protein mass, mainly from the skeletal muscle. Studies on protein turnover describe an increased protein breakdown and, to a lesser extent, an increased whole-body protein synthesis, as well as an increased flux of amino acids from the periphery to the liver. Appropriate nutrition could limit protein catabolism. Nutritional support limits but does not stop the loss of total body protein mass occurring in acute severe illness. Its impact on protein kinetics is so far controversial, probably due to the various methodologies and characteristics of nutritional support used in the studies. Maintaining calorie balance alone the days after an insult does not clearly lead to an improved clinical outcome. In contrast, protein intakes between 1.2 and 1.5 g/kg body weight/day with neutral energy balance minimize total body protein mass loss. Glutamine and possibly leucine may improve clinical outcome, but it is unclear whether these benefits occur through an impact on total body protein mass and its turnover, or through other mechanisms. Present recommendations suggest providing 20 - 25 kcal/kg/day over the first 72 - 96 hours and increasing energy intake to target thereafter. Simultaneously, protein intake should be between 1.2 and 1.5 g/kg/day. Enteral immunonutrition enriched with arginine, nucleotides, and omega-3 fatty acids is indicated in patients with trauma, acute respiratory distress syndrome (ARDS), and mild sepsis. Glutamine (0.2 - 0.4 g/kg/day of L-glutamine) should be added to enteral nutrition in burn and trauma patients (ESPEN guidelines 2006) and to parenteral nutrition, in the form of dipeptides, in intensive care unit (ICU) patients in general (ESPEN guidelines 2009).

Nutritional state, energy intakes and energy expenditure of amyotrophic lateral sclerosis (ALS) patients.

Amyotrophic lateral sclerosis (ALS) alters nutritional state, energy intake and energy expenditure. This article aims at reviewing present knowledge on these topics in order to determine energy requirements for maintaining a neutral energy balance in ALS patients. Maintaining a neutral energy balance prevents malnutrition and its complications and may improve physical functioning, quality of life and survival. Prevalence of malnutrition varies between 16 and 55% in ALS patients. Energy intakes are below recommended dietary allowances in 70% of ALS patients at least. These elements suggest a chronic negative energy balance with an imbalance between requirements and intakes. While insufficient intakes can be compensated with nutritional support, the energy requirements are unclear. Studies generally report hypermetabolism in ALS patients. Estimation of total energy expenditure and as a corollary energy needs, necessitates taking into account this hypermetabolism, physical activity and possibly mechanical ventilation. The review suggests a flow chart for optimal nutritional follow-up in clinics. Further studies are required to assess whether optimal nutritional follow-up improves outcome.

Decreased food intake is a risk factor for mortality in hospitalised patients: the NutritionDay survey 2006.

BACKGROUND & AIMS: Malnutrition is a known risk factor for the development of complications in hospitalised patients. We determined whether eating only fractions of the meals served is an independent risk factor for mortality. METHODS: The NutritionDay is a multinational one-day cross-sectional survey of nutritional factors and food intake in 16,290 adult hospitalised patients on January 19th 2006. The effect of food intake and nutritional factors on death in hospital within 30 days was assessed in a competing risk analysis. RESULTS: More than half of the patients did not eat their full meal provided by the hospital. Decreased food intake on NutritionDay or during the previous week was associated with an increased risk of dying, even after adjustment for various patient and disease related factors. Adjusted hazard ratio for dying when eating about a quarter of the meal on NutritionDay was 2.10 (1.53-2.89); when eating nothing 3.02 (2.11-4.32). More than half of the patients who ate less than a quarter of their meal did not receive artificial nutrition support. Only 25% patients eating nothing at lunch receive artificial nutrition support. CONCLUSION: Many hospitalised patients in European hospitals eat less food than provided as regular meal. This decreased food intake represents an independent risk factor for hospital mortality.

Nutrition in care homes and home care: how to implement adequate strategies (report of the Brussels Forum (22-23 November 2007)).

BACKGROUND & AIMS: Undernutrition in home care and care home settings is an unrecognized problem with significant consequences. The present work was edited after a forum concerning nutrition in these settings was held in Brussels in order to tackle the problem. METHODS: Various aspects of the question were addressed with the participation of scientific experts. The proceedings of the forum were edited and completed by a review of previously published material. RESULTS: Prevalence of undernutrition in home care and care home settings varies between 15% and 65%. Causes of undernutrition are various: medical, social, environmental, organizational and financial. Lack of alertness of individuals, their relatives and health-care professionals play an important role. Undernutrition enhances the risk of infection, hospitalization, mortality and alter the quality of life. Moreover, undernutrition related-disease is an economic burden in most countries. Nutritional assessment should be part of routine global management. Nutritional support combined with physical training and an improved ambiance during meals is mandatory. Awareness, information and collaboration with all the stakeholders should facilitate implementation of nutritional strategies. CONCLUSIONS: Undernutrition in home care and care home settings is a considerable problem and measures should be taken to prevent and treat it.

Insulin resistance, obesity and breast cancer risk.

Breast cancer (BC) is one of the most important problems of public health. Among the avoidable risk factors during a woman's life, overweight and obesity are very important ones. Furthermore they are increasing worldwide. The risk of breast cancer is traditionally linked to obesity in postmenopausal women; conversely, it is neutral or even protective in premenopausal women. Since the initiator and promoter factors for BC act over a long time, it seems unlikely that the menopausal transition may have too big an impact on the role of obesity in the magnitude of the risk. We reviewed the literature in an attempt to understand this paradox, with particular attention to the body fat distribution and its impact on insulin resistance. The association of insulin resistance and obesity with BC risk are biologically plausible and consistent. Estradiol (E2) and IGFs act as mitogens in breast cancer cells. They act together and reciprocally. However the clinical and biological methods to assess the impact of insulin resistance are not always accurate. Furthermore insulin resistance is far from being a constant feature in obesity, particularly in premenopausal women; this complicates the analysis and explains the discrepancies in large prospective trials. The most consistent clinical feature to assess risk across epidemiological studies seems to be weight gain during lifetime. Loss of weight is associated with a lower risk for postmenopausal BC compared with weight maintenance. This observation should be an encouragement for women since loss of weight may be an effective strategy for breast cancer risk reduction.

[Relationship between nutritional intervention and quality of life in cancer patients]. / Relación entre la intervención nutricional y la calidad de vida en el paciente con cáncer.

Quality of life (QOL) is a concept assessing physical, psychological and social factors which are influencing the patients' well being. Cancer and its therapy induce severe metabolic changes associated with QOL impairment. These alterations contribute to an increased energy wasting and a decreased food intake. Besides, it may lead to tumoral cachexia due to the complex interactions between pro-inflammatory cytokines and the host metabolism. On the other hand, and beyond physical impairments and metabolic effects from cancer, patients often suffer from psychological stress, such as depression. A nutritional intervention should be implemented as soon as cancer is diagnosed. It should be appropriate to the individual needs of the patient, considering the type of oncologic treatment (whether it is curative or palliative), the clinical conditions and the nutritional status. The aim is to reduce or even revert nutritional status impairment, improve the general condition, and subsequently improve quality of life. The primary focus of nutritional intervention accompanying oncologic treatment intended to cure is on the optimization of the balance between energy waste and food intake. Thus trying to achieve further specific purposes such as a decrease of rate of complications and an amelioration of the response and tolerance to the oncologic therapy. The purpose of nutritional support in palliative care is controlling the symptoms related to food intake and delaying the loss of autonomy. And by this means maintaining or improving patients' QOL. It is corraborated by a literature review, that nutritional therapy should form part of the integral oncological support since it contributes considerably to a QOL improvement. Because of the possibility to identify the patients' needs and expectations by assessing their QOL it should be generally included into their nutritional evaluation to be able to tailor the adequate nutritional support.

Relación entre la intervención nutricional y la calidad de vida en el paciente con cáncer / Relationship between nutritional intervention and quality of life in cancer patients

La Calidad de Vida (CdV) es un concepto que evalúa los factores físicos, psicológicos y sociales, los cuales influencian el bienestar de los pacientes. El cáncer y su tratamiento reinduce en severos cambios metabólicos asociados a un deterioro de la CdV. Dichas alteraciones contribuyen al incremento del gasto energético y a una disminución de la ingesta alimentaria. Así mismo, esto puede conllevar a desarrollarse la caquexia tumoral, debido a la complejidad de interacciones entre citoquinas proinflamatorias y el metabolismo del huésped. Por otro lado, y más allá de las alteraciones físicas y de los efectos metabólicos del cáncer, los pacientes frecuentemente sufren también de stress psicológico, como la depresión. La intervención nutricional se podría implementar tan pronto como el cáncer es diagnosticado. De acuerdo a las necesidades del paciente, considerando el tipo de tratamiento oncológico (si es curativo o paliativo), las condiciones clínicas y el estado nutricional. Con el objetivo de reducir o incluso revertir el deterioro del estado nutricional, mejorar el estado general y consecuentemente mejorar la CdV. La intervención nutricional, que acompaña el tratamiento oncológico con la intención de curar, se centra principalmente, en la optimización del balance entre el gasto energético y la ingesta. Para alcanzar objetivos específicos tales como: disminución de la tasa de complicaciones, mejorar la respuesta y la tolerancia al tratamiento oncológico. El soporte nutricional en cuidados paliativos, se enfoca en controlar los síntomas relacionados con la ingesta de alimentos y retrasar la pérdida de autonomía. Con la finalidad de mantener o incluso mejorar, la CdV de los pacientes. La revisión de la literatura, corrobora que el tratamiento nutricional debe hacer parte dentro del soporte oncológico integral, porque contribuye considerablemente a la mejoría de la CdV. Debido a la posibilidad de identificar las necesidades y expectativas de los pacientes evaluando su CdV, ésta se podría incluir dentro de la evaluación nutricional, para elaborar un soporte nutricional adecuado, a la medida del paciente
