Abstract
Biomarkers are objective tools with an important role for diagnosis, prognosis and therapy optimization in patients with heart failure (HF). To date, natriuretic peptides are closest to optimal biomarker standards for clinical implications in HF. Therefore, the efforts to identify and test new biomarkers in HF are reasonable and justified. Along the natural history of HF, cardiac cachexia may develop, and once at this stage, patient performance and prognosis is particularly poor. For these reasons, numerous biomarkers reflecting hormonal, inflammatory and oxidative stress pathways have been investigated, but only a few convey relevant information. The complex pathophysiology of HF appears far too complex to be embraced by a single biomarker; thus, a combined approach appears reasonable. With these considerations, we have reviewed the recent developments in the field to highlight key candidates with diagnostic, prognostic and therapy optimization properties, either alone or in combination.

Abstract
BACKGROUND Malnutrition and cachexia were a frequent problem in lung cancer and increases the risks of morbidity and mortality in these patients. Bioelectrical impedance analysis (BIA) is easy, non-invasive and reproducible method that can be performed. AIM Evaluate nutritional status in patients with primary lung cancer by Mini Nutritional Assessment (MNA), BIA and anthropometric values (weight, arm and calf circumferences) and correlate the nutritional parameters to severity of cancer and histopathology. METHODS The nutritional status of 73 cases of primary lung cancer was evaluated by anthropometric parameters, MNA test and impedencemetrie Results: According to body mass index (BMI), malnutrition, overweight and obesity were noted in 34,2%, 13,7% and 5,5%. According to BMI, free-fat mass index (FFMI) and fat mass index (FMI), the investigations occurred malnutrition and depletion of muscle in respectively 19,2% and 23,3% of cases. Fat depletion was noted in 21,9%. Overweight and obesity were detected in 6,8% and 5,5% of cases. Assessment by MNA, revealed that 28,7% of patients were already malnourished and 49,3% of patients were at risk of malnutrition. A significant correlation existed between the score of MNA and arm and calf circumferences, FFMI and FMI. FMI was significantly lower in group of patients with small lung carcinoma. CONCLUSION Only FFMI allows early detection of malnutrition in cancer patients overestimated by measuring BMI and arm circumference was the better indicator of depletion of muscle.

Abstract
BACKGROUND Cachexia may occur in 40% of cancer patients, representing the major cause of death in more than 20% of them. The aim of this study was to investigate the role of leptin, ghrelin and obestatin as diagnostic and predictive markers of cachexia in oncologic patients. Their impact on patient survival was also evaluated. METHODS 140 adults with different cancer diagnoses were recruited. Thirty healthy volunteers served as control. Serum ghrelin, obestatin and leptin were tested at baseline and after a follow-up period of 18 months. RESULTS Ghrelin levels were significantly higher in cancer patients than in healthy subjects (573.31 ± 130 vs 320.20 ± 66.48 ng/ml, p < 0.0001), while obestatin (17.42 ± 7.12 vs 24.89 ± 5.54 ng/ml, p < 0.0001) and leptin (38.4 ± 21.2 vs 76.28 ± 17.48 ng/ml, p < 0.0001) values were lower. At ROC analyses the diagnostic profile of ghrelin (AUC 0.962; sensitivity 83%; specificity 98%), obestatin (AUC 0.798; sensitivity 74.5%; specificity 81.5%) and leptin (AUC 0.828; sensitivity 79%; specificity 73%) was superior to that of albumin (AUC 0.547; sensitivity 63%, specificity 69.4%) for detecting cachexia among cancer patients. On Cox multivariate analyses ghrelin (HR 1.02; 95% CI 1.01 - 1.03; p < 0.0001) and leptin (HR 0.94; 95% CI 0.92 - 0.96; p < 0.0001) were significant predictors of death even after correction for other known risk factors such as presence of metastasis and chronic kidney disease. CONCLUSION Ghrelin and leptin are promising biomarkers to diagnose cachexia and to predict survival in cancer patients.

Abstract
CONTEXT Cancer cachexia occurs in most patients suffering from solid malignancies. Recent works suggest paraneoplastic mechanisms. Empirical studies also found autonomic dysfunction in cancer patients, but comprehensive evaluation of the peripheral nervous system is lacking. OBJECTIVES To further understand the role of the autonomic and peripheral nervous system in cancer cachexia to guide treatment. METHODS We prospectively investigated cachectic cancer patients for parasympathetic autonomic dysfunction with a time-domain-based analysis of heart rate variability (breathing at rest, deep breath, and in response to the Valsalva maneuver). Blood pressure changes after the Valsalva maneuver were used as a marker of the sympathetic noradrenergic system. Orthostatic hypertension was investigated in response to active standing. We used a noninvasive continuous beat-to-beat heart rate assessment and blood pressure monitoring. The sympathetic cholinergic nervous system was evaluated with the sympathetic skin response. A detailed neurological examination, nerve conduction studies, and electromyography also were conducted. RESULTS A total of 13 patients were enrolled (median age 66 years). Median time from inclusion until death was 3.5 months. About 12 of the 13 patients showed abnormal results in at least one autonomic test. Sympathetic noradrenergic and cholinergic abnormalities were discovered in six patients each and five patients had orthostatic hypotension. Only one patient showed abnormal results in parasympathetic cholinergic tests. Asymptomatic large fiber polyneuropathy was detected in eight patients. CONCLUSION Large fiber polyneuropathy coincides with autonomic dysfunction in cachectic cancer patients. Our findings suggest a relevant role of sympathetic impairment in cancer cachexia.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) patients have the highest risk of developing cachexia, which is a direct cause of reduced quality of life and shorter survival. Novel biomarkers to identify patients at risk of cachexia are needed and might have a substantial impact on clinical management. Here we investigated the prognostic value and association of SELP-rs6136, IL6-rs1800796 and AKT1-rs1130233 polymorphisms with cachexia in PDAC. Genotyping was performed in DNA from blood samples of a test and validation cohorts of 151 and 152 chemo-naive locally-advanced/metastatic PDAC patients, respectively. The association of SELP-rs6136, IL6-rs1800796 and AKT1-rs1130233 polymorphisms with cachexia as well as the correlation between cachexia and the candidate polymorphisms and overall survival were analyzed. Akt expression and phosphorylation in muscle biopsies were evaluated by specific ELISA assays. SELP-rs6136-AA and AKT1-rs1130233-AA/GA genotypes were associated with increased risk of developing cachexia in both cohorts (SELP: p = 0.011 and p = 0.045; AKT1: p = 0.004 and p = 0.019 for the first and second cohorts, respectively), while patients carrying AKT1-rs1130233-GG survived significantly longer (p = 0.002 and p = 0.004 for the first and second cohorts, respectively). In the multivariate analysis AKT1-rs1130233-AA/GA genotypes were significant predictors for shorter survival, with an increased risk of death of 1.7 (p = 0.002) and 1.6 (p = 0.004), in the first and second cohorts, respectively. This might be explained by the reduced phosphorylation of Akt1 in muscle biopsies from patients harboring AKT1-rs1130233-AA/GA (p = 0.003), favoring apoptosis induction. In conclusion, SELP and AKT1 polymorphisms may play a role in the risk of cachexia and death in PDAC patients, and should be further evaluated in larger prospective studies.

Abstract
Cachexia is frequently described in patients with pancreatic ductal adenocarcinoma (PDAC) and is associated with reduced survival and quality of life. Unfortunately, the therapeutic options of this multi-factorial and complex syndrome are limited. This is due to the fact that, despite extensive preclinical and clinical research, the underlying pathological mechanisms leading to PDAC-associated cachexia are still not fully understood. Furthermore, there is still a lack of consensus on the definition of cachexia, which complicates the standardization of diagnosis and treatment as well as the analysis of the current literature. In order to provide an efficient therapy for cachexia, an early and reliable diagnosis and consistent monitoring is required, which can be challenging especially in obese patients. Although many substances have been tested in clinical and preclinical settings, so far none of them have been proven to have a long-term effect in ameliorating cancer-associated cachexia. However, recent studies have demonstrated that multidimensional therapeutic modalities are able to alleviate pancreatic cancer-associated cachexia and ultimately improve patients’ outcome. In this current review, we propose a stepwise and pragmatic approach to facilitate and standardize the treatment of cachexia in pancreatic cancer patients. This strategy consists of nutritional, dietary, pharmacological, physical and psychological methods.

Abstract
The aim of this research was to perform the nutritional screening and clinical assessment of malnutrition and of cachexia as well as the need for enteral nutritional support. We used an international questionnaire for nutrition screening and clinical assessment of malnutrition. 103 cancer patients participated in the research. The results indicate that 80patients (78%) have recently unintentionally lost weight in the last six months. Of those 80 patients 12 (15%) have lost more than 15 kilograms. Three patients (3%) suffer from hunger because of their inability to eat. Presence of multiple (3 or more) symptoms (nausea, vomiting, diarrhea or anorexia) was reported by 11 patients (11%). Severe work dysfunction was found in 28 patients (27%). 14 patients (14%) experience significant loss of musculature (musculus quadriceps femoris, musculus deltoideus). The obtained results indicate that 15patients (14%) are severely, and 39 patients (38%) are moderately undernourished. This survey confirmed the significance of nutritional screening in cancer patients, as it detected 30 patients (29%) who required introduction of enteral nutrition.

Abstract
Background Cachexia affects the majority of patients with advanced cancer and is associated with a reduction in treatment tolerance, response to therapy, and duration of survival. One impediment towards the effective treatment of cachexia is a validated classification system. Methods 41 patients with resectable upper gastrointestinal (GI) or pancreatic cancer underwent characterisation for cachexia based on weight-loss (WL) and/or low muscularity (LM). Four diagnostic criteria were used >5%WL, >10%WL, LM, and LM+>2%WL. All patients underwent biopsy of the rectus muscle. Analysis included immunohistochemistry for fibre size and type, protein and nucleic acid concentration, Western blots for markers of autophagy, SMAD signalling, and inflammation. Findings Compared with non-cachectic cancer patients, patients with LM or LM+>2%WL, mean muscle fibre diameter was reduced by about 25% (p = 0.02 and p = 0.001 respectively). No significant difference in fibre diameter was observed if patients had WL alone. Regardless of classification, there was no difference in fibre number or proportion of fibre type across all myosin heavy chain isoforms. Mean muscle protein content was reduced and the ratio of RNA/DNA decreased in patients with either >5%WL or LM+>2%WL. Compared with non-cachectic patients, SMAD3 protein levels were increased in patients with >5%WL (p = 0.022) and with >10%WL, beclin (p = 0.05) and ATG5 (p = 0.01) protein levels were increased. There were no differences in phospho-NFkB or phospho-STAT3 levels across any of the groups. Conclusion Muscle fibre size, biochemical composition and pathway phenotype can vary according to whether the diagnostic criteria for cachexia are based on weight loss alone, a measure of low muscularity alone or a combination of the two. For intervention trials where the primary end-point is a change in muscle mass or function, use of combined diagnostic criteria may allow identification of a more homogeneous patient cohort, reduce the sample size required and enhance the time scale within which trials can be conducted.

Abstract
CONTEXT Cancer cachexia syndrome (CCS) is often accompanied by psychosocial consequences (PSC). To alleviate PSC, a systematic assessment method is required. Currently, few assessment tools are available (e.g., Functional Assessment of Anorexia/Cachexia Therapy). There is no systematic assessment tool that captures the PSC of CCS. OBJECTIVES To develop a pilot item bank to assess the PSC of CCS. METHODS A total of 132 questions, generated from patient answers in a previous study, were reduced to 121 items by content analysis and evaluation by multidisciplinary experts (doctor, nutritionists, and nurses). In our two-step, cross-sectional study, patients, judged by staff to have PSC of CCS, were included, and the questions were randomly allocated to the patients. Questions were evaluated for understandability and triggering emotions, and patients were asked to provide a response using a four-point Likert scale. Subsequently, problematic questions were revised, reformulated, and retested. RESULTS A total of 20 patients with a variety of tumor types participated. Of the 121 questions, 31 had to be reformulated after Step 1 and were retested in Step 2, after which seven were again evaluated as not being perfectly comprehensible. In Step 1, 22 questions were found to trigger emotions, but no item required remodeling. Item performance using the Likert scale revealed no consistent floor or ceiling effects. Our final pilot question bank comprised 117 questions. CONCLUSION The final item bank contains questions that are understood and accepted by the patients. This item bank now needs to be developed into a measurement tool that groups items into domains and can be used in future research studies.

Abstract
Cachexia and sarcopenia present several analogies in both the pathogenic mechanisms and the clinical picture. The loss of muscle mass and strength is a hallmark of these two clinical conditions. Although frequently overlapping and often indistinguishable, especially in old individuals, these two conditions should be considered distinct clinical entities. A prompt and accurate patient evaluation, guiding the physician through a proper differential diagnostic procedure and providing the best therapeutic options, is recommended. Given the several commonalities between cachexia and sarcopenia, it is likely that the therapeutic approaches may prove effective in both conditions. This review focuses on the most recent available literature and aims at providing physicians with the correct tools that are available to aid in diagnosing these two different entities that often clinically overlap. Currently available or proposed therapeutic strategies for pre-cachexia, cachexia and sarcopenia are also briefly described.

Abstract
PURPOSE OF REVIEW Cachexia development is a feature of cancer as well as other chronic diseases. Fat mass loss appears of greatest importance in cachexia, as it is related to poorer survival. Zinc-α2-glycoprotein (ZAG), firstly isolated in human plasma 50 years ago, has emerged as a novel adipokine, which plays an important role in mobilization and utilization of lipids. This review will focus on recent evidences of ZAG as a fat catabolic marker in cancer and other diseases complicated by cachexia. RECENT FINDINGS ZAG is a lipolytic factor produced by certain cachexia-inducing tumuors and by adipose tissue. It increases lipolysis in white adipose tissue through cyclic-AMP pathway and stimulates uncoupling protein-1 in brown adipose tissue leading to heat generation. In cancer cachexia, ZAG release from white adipocytes is elevated and closely related to body weight loss. In cardiac cachexia, ZAG and circulating free fatty acids are closely related, suggesting a causative role in fat catabolism. SUMMARY ZAG may play an important role, probably as an autocrine/paracrine modulator of adipose mass in cachexia. A better comprehension of ZAG involvement in fat wasting mechanisms will be useful in the development of new therapeutic agents.

Abstract
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disorder of the lung and whole body caused mainly by tobacco smoking. Patients with advanced COPD are in a state of undernutrition, referred to as pulmonary cachexia; the exercise performance and quality of life (QOL) of these patients are deteriorated, the vital prognosis is unfavorable, and the medico-economic burden posed by poorly nourished COPD patients is high. The mainstays of COPD treatment are pharmacotherapy, mainly with bronchodilators, and non-pharmacotherapeutic approaches such as respiratory rehabilitation and nutrition counseling. Nutritional supplement therapy, consisting primarily of high calorie intake, has been demonstrated to be effective for maintaining and improving the muscle strength and exercise tolerance in poorly nourished COPD patients. The efficacy of intake of various nutrients, besides a high calorie intake, for amelioration of the disease state of COPD has also been reported. The roles of adipokines in the pathophysiology of COPD have begun to receive attention recently, and not only their regulatory effects on appetite and nutritional status, but also their influence on systemic inflammation have been increasingly clarified. We review the papers on COPD and nutrition and discuss the role of nutritional supplement therapy in the treatment of COPD.

Abstract
BACKGROUND COPD, a leading cause of mortality is currently assessed by spirometry (forced expiratory volume in 1 second, FEV(1)). However FEV(1) does not correlate with patient mortality. ECLIPSE (Evaluation of Chronic obstructive pulmonary disease to Longitudinally Identify Predictive Surrogate Endpoints) aims to identify biomarkers that correlate with clinically relevant COPD subtypes, and to assess how these may predict disease progression. New methods were developed and validated to evaluate small molecules as potential diagnostic tools in patients with COPD, COPD related cachexia and cancer related cachexia. METHODS AND FINDINGS quantitative LC-MS/MS was developed to measure 34 amino acids and dipeptides for stratification of patient groups. Subsets of the ECLIPSE patients were used to assess biomarkers of lung obstruction; GOLD IV (n = 30) versus control (n = 30); emphysema (n = 38) versus airways disease (n = 21) and cachexia (n = 30) versus normal body mass index (n = 30). Serum from cachexic (n = 7) and non-cachexic (n = 5) pancreatic cancer patients were included as controls. Targeted LC-MS/MS distinguished GOLD IV patients from controls, patients with and without emphysema and patients with and without cachexia. Glutamine, aspartate and arginine were significantly increased (p < 0.05; FDR adjustment α < 0.1) in cachexia, emphysema and GOLD IV patients and aminoadipate was decreased. Several amino acid concentrations were significantly altered in patients with COPD but not patients with pancreatic cancer (serine, sarcosine, tryptophan, BCAAs and 3-methylhistdine). Increased γ-aminobutyrate (GABA, p < 0.01) levels were specific to cachexia in patients with pancreatic cancer. β-aminoisobutyrate, 1-methylhistidine and asparagine (p < 0.05) were common across the patients with cachexia from both the COPD and pancreatic cancer cohorts. CONCLUSION these results demonstrate that a metabolomic fingerprint has potential to stratify patients for the treatment of COPD and may provide a means of assessing response to therapy. GOLD IV patients were distinguished from smoker control subjects, patients with emphysema were distinguished from those without emphysema and COPD patients displaying cachexia were distinguished from those not displaying cachexia. General markers of cachexia were discovered reflecting both COPD- and pancreatic cancer-related cachexia (increased glutamine, aspartate, arginine, and asparagine and decreased aminoadipate, β-aminoisobutyrate and 1-methylhistidine). Metabolomic biomarkers, particularly altered levels of GABA, could be exploited as a way of monitoring treatment efficacy and tumour recurrence for patients with pancreatic cancer experiencing cachexia.

Abstract
BACKGROUND Disease-related malnutrition is highly prevalent in hospital patients and varies from 25-40%. Early nutritional screening of patients at admission helps to improve recognition of malnourished patients to allow early interventions and enhance clinical outcomes. METHOD A total of 104 preoperative surgical patients with oesophageal (34), stomach (17) or pancreatic cancer (53) were recruited in our study. The risk of malnutrition was examined using the quick-and-easy Malnutrition Universal Screening Tool (MUST). Anthropometric data and information on percent weight change over the past six months, unintentional weight loss, dietician referrals, and history of nutritional intervention were collected. RESULTS A total of 75% of our participants were at high malnutrition risk with a mean (±SD) percentage weight loss of 5.18 (±6.23)%, despite a mean BMI of 26.09 (±5.73) kgm-2. Participants with a significantly higher percent weight loss, unintentional weight loss, dietician referral and nutritional intervention had a higher risk of malnutrition (p<0.05). Presence of unintentional weight loss was the only significant predictor (OR 3.22; 95%CI 1.23, 8.40) associated with risk of malnutrition after adjusted for all confounders. CONCLUSION In conclusion, our findings highlight the importance of routine screening of malnutrition in oncology patients. Medical personnel must be aware that unintentional weight loss is an important predictor of malnutrition risks even if the patient’s BMI is not suggestive of malnutrition.

Abstract
This review aims to highlight the synergies between clinical nutrition, body composition and cancer treatment. Body composition is already a powerful tool to diagnose cachexia and determine response to nutritionnal intervention. It may be used in the future to fine tune body surface area (BSA) based drug dose determination thanks to its capacity to predict chemotoxicity. The overall aim of nutritionnal intervention is to optimize the oncological care by reducing treatment interruptions and improving the quality of life. However, to achieve this goal, nutritionnal intervention has to be very accurate as most of the failures result from inappropriate intervention.

Abstract
PURPOSE OF REVIEW Malnutrition, fatigue, frailty, vulnerability, sarcopenia and cachexia all phenotypically present with the same features because they are subject to the operation of similar mechanistic factors. However, the conditions referred to above differ by which mechanism dominates the cause of the clinical condition. This review discusses the overlap and differences, which distinguish as well as unite these different conditions and allow a rationale for treatment. RECENT FINDINGS In the continuum of malnutrition, cachexia, sarcopenia and frailty the recent activities focus on two areas. The first is a better understanding of the mechanisms of cachexia and sarcopenia and frailty. In particular, the differential effects of cytokines on muscle and on the hypothalamic system. The effects of inactivity promoting the loss of body mass in cachexia and sarcopenia as well as the positive effects of exercise. The second is the development of a synthesis of available literature to develop consensus documents about the definition, causes, diagnosis and treatment of cachexia, sarcopenia and frailty. SUMMARY Loss of body tissues resulting in wasting is a common phenotype for several different conditions which can be caused by a combination of reduced food intake, excessive requirements, altered metabolism, sepsis, trauma, ageing and inactivity. They have been referred to loosely as malnutrition but in not all will respond to simply providing nutrients. In this review the common features and the differences as they relate to cause and response to treatment are discussed.

Abstract
Diabetes can be associated with a number of peripheral nerve disorders. The commonest is slowly-progressive axonal distal symmetrical sensori-motor neuropathy. Sensory loss and positive sensory symptoms are its main manifestations. Lumbosacral radiculoplexus neuropathy (LSRPN) is a distinct entity, accompanied by severe lumbar, hip, leg pain and weight loss, with subsequent weakness. Although typically unilateral, bilaterality is described, with spontaneous recovery usual over several months. The upper limb counterpart, cervical radiculoplexus neuropathy is rare. Acute painful neuropathies, including "diabetic neuropathic cachexia", are infrequent. Accompanying weight loss is usual and burning pains in the extremities are severe. Insulin-triggered acute painful neuropathy is well-described although infrequent and still poorly-understood. Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) represents an immune-mediated treatable disorder, usually causing prominent diffuse motor weakness, which was described as more common in diabetics. More recent epidemiological data have however been conflicting and it is possible that CIDP is no more frequent in diabetics than in the general population. Diagnosis is made by electrophysiology and cerebrospinal fluid analysis. A painless diabetic motor neuropathy, thought to be caused by ischaemic injury and microvasculitis, has recently been postulated as separate from LSRPN and CIDP. Other focal and multifocal neuropathies that can occur in diabetics are cranial or truncal. Entrapment neuropathies are more often of median and ulnar nerves, and may in some cases benefit from decompression. Finally, autonomic neuropathies are well-described in diabetes and can be diverse in presentation with cardiovascular, gastrointestinal, urogenital and sudomotor manifestations. Their management can be difficult with debilitating symptoms despite treatment.

Abstract
Cancer anorexia-cachexia syndrome (CACS) is a devastating and debilitating aspect at any stage of malignancy. It presents primarily as anorexia, weight loss and muscle wasting secondary to inadequate oral intake and metabolic changes. This syndrome is highly prevalent among cancer patients, has a large impact on morbidity and mortality, and impinges on patient quality of life. The pathogenic mechanisms of CACS are multifactorial. It is suggested to be the result of tumor-host interactions and cytokines have a siginificant role. Diagnosis of cancer cachexia is complex and multifaceted and requires meticulous clinical examination of the patient. The challenge for clinicians is to know how best to manage the symptoms of weight loss and anorexia for optimal patient outcome. This article outlines the diagnosis of cancer cachexia, reviews its impact on patient quality of life and survival, and updates the reader on potential therapies that may suppress it.

Abstract
Nutritional status is often impaired in ambulatory rehabilitation patients. Wasting conditions can be classified as starvation, sarcopenia or cachexia but differences between these are not well defined, and misdiagnosis may lead to inappropriate intervention. A secondary analysis of data from 187 ambulatory rehabilitation patients aged >=60 years aimed to identify patients with one or more wasting condition, and investigate the impact on common rehabilitation outcomes. Starvation was defined by fat-free mass index and the Council on Nutrition Appetite Questionnaire score; sarcopenia by fat-free mass index and quadriceps strength; and cachexia by fat-free mass index and serum C-reactive protein. Selected rehabilitation outcomes were compared for those who were, and those who were not, identified as having one or more wasting condition. Of those identified with starvation (n=30), all were also identified as sarcopenic and 20 as cachectic; of those identified as sarcopenic (n=75), 30 had starvation and 37 were cachectic; and of those identified as cachectic (n=37), 20 had starvation and all were sarcopenic. Twenty participants were identified as having all three conditions. Those with starvation had higher level of depression (p=0.003), lower self-rated health (p=0.032), and lower levels of physical function (motor p=0.006; process p=0.004) than those with no evidence of a wasting condition. Those who had sarcopenia had lower physical function (motor p=0.012; process p=0.003) as did those with cachexia (motor p=0.025; process p=0.042). Results suggest problems in operationalising definitions in an ambulatory clinical setting. The overlap identified in this analysis suggests that up to 40% (75/187) of patients could be misidentified and prescribed inappropriate nutritional support.

Abstract
Adequate nutrition plays a major role, both in prevention and treatment of gastrointestinal cancer. There are such factors as the cellulose content in food ration, the consumption of fresh fruits and vegetables, vitamins, physical activity. Cancer cachexia are observed at 70% of oncology patients in the terminal stage of cancer. Purposes of nutritional support are improvement of the quality of life, in particular terminally ill, the reduction of the length of hospital stay and costs of treatment, the prevention infectious and postoperative complications. The preference must be given enteral versus parenteral nutrition. In this work was studied possibilities of nutritional support for correction of malnutrition in the patient with gastrointestinal cancer. It is shown that the enteral nutrition contributes to improvement of nutritional status, prevents development of cachexia, improves the quality of life.

Abstract
Superior mesenteric artery (SMA) syndrome is a rare cause of obstruction of 3rd part of duodenum between abdominal aorta and the overlying superior mesenteric artery caused by decrease in the angle between the two vessels as a result of rapid loss of retroperitoneal fat. It is seen in conditions causing severe weight loss and catabolic states. We report a case of pulmonary tuberculosis leading to superior mesenteric artery syndrome.

Abstract
Although the prevalence of rheumatic fever has greatly decreased in developed countries, rheumatic mitral stenosis still causes significant morbidity and mortality. Symptomatic patients have a poor prognosis, with a 0 to 15% 10-year survival rate, particularly if percutaneous or surgical intervention are contraindicated or considered high risk. We present a case of severe rheumatic mitral stenosis with an evolution over 4 decades, in which exceptional venous distention has established.

Abstract
PURPOSE OF REVIEW The review summarizes and discusses the proposed new definitions for sarcopenia and cachexia. It also highlights the overlapping of both conditions and the fact that these conditions frequently occur in elderly patients. RECENT FINDINGS Sarcopenia is now recognized as a multifactorial geriatric syndrome. Cachexia is defined as a metabolic syndrome in which inflammation is the key feature and so cachexia can be an underlying condition of sarcopenia. Recently, cachexia has been defined as 'a complex metabolic syndrome associated with underlying illness and characterized by loss of muscle mass with or without loss of fat mass. The prominent clinical feature of cachexia is weight loss in adults'. Different recommendations have been proposed for the diagnosis of sarcopenia. At present, all definitions combine an assessment of muscle mass and muscle function (strength or physical performances such as gait speed). However, the relevance and the validation of these evolving definitions need to be assessed in future studies. SUMMARY Although the recent definitions of sarcopenia and cachexia boost research in the field and define distinct entities, the cause behind the loss of muscle mass (whether cachexia or sarcopenia) may, however, be indistinguishable in clinical practice. Therefore, new therapeutic approaches, alone or in combination, could be targeted on both conditions.
