BACKGROUND & AIMS: Mediterranean diet (MeDi) is considered as a key component for healthy aging, including prevention of age-related disability, while its association with frailty, independent of disability has never been assessed. Our objective was to investigate the relation between MeDi adherence and frailty incidence among persons aged ≥75 years participating at the prospective population-based French Three-City Study. METHODS: The study sample consisted of 560 initially non-frail participants of the Three-City-Bordeaux center, seen at the 2009-2010 follow-up, and re-examined two years later...

In this article, we investigate the impact of job displacement on women's first-birth rates as well as the variation in this effect over the business cycle. We use mass layoffs to estimate the causal effects of involuntary job loss on fertility in the short and medium term, up to five years after displacement. Our analysis is based on rich administrative data from Germany, with an observation period spanning more than 20 years. We apply inverse probability weighting (IPW) to flexibly control for the observed differences between women who were and were not displaced...

OBJECTIVES: Sarcopenia refers to the involuntary loss of skeletal muscle and is a predictor of physical disability/mortality. Its pathogenesis is poorly understood, although roles for altered hypoxic signaling, oxidative stress, adipokines and inflammatory mediators have been suggested. Sarcopenia also occurs upon exposure to the hypoxia of high altitude. Using data from the Caudwell Xtreme Everest expedition we therefore sought to analyze the extent of hypoxia-induced body composition changes and identify putative pathways associated with fat-free mass (FFM) and fat mass (FM) loss...

A 76-year-old woman complained of painful dysphagia and loss of weight. Esophagoscopy results were negative, whereas computed tomography (CT) disclosed a 25-mm mediastinal tumor without a connection to the esophagus. A diagnosis of nutcracker esophagus was made on high-resolution esophageal manometry. Peroral endoscopic esophageal myotomy failed to improve the symptoms. Right video thoracoscopy allowed resection of the tumor, which looked like a neurogenic tumor of the posterior mediastinum that developed from the right vagus nerve...

Cancer cachexia is characterised by involuntary weight loss associated with systemic inflammation and metabolic changes. Studies aimed at maintaining lean body mass in cachectic tumour-bearing hosts have made important contributions reducing the number of deaths and improving the quality of life. In recent years, leucine has demonstrated effective action in maintaining lean body mass by decreasing muscle protein degradation. Currently, there is a growing need to understand how leucine stimulates protein synthesis and acts protectively in a cachectic organism...

Cachexia in the context of heart failure (HF) has been termed cardiac cachexia, and represents a progressive involuntary weight loss. Cachexia is mainly the result of an imbalance in the homeostasis of muscle protein synthesis and degradation due to a lower activity of protein synthesis pathways and an over-activation of protein degradation. In addition, muscle wasting leads to of impaired functional capacity, even after adjusting for clinical relevant variables in patients with HF. However, there is no sufficient therapeutic strategy in muscle wasting in HF patients and very few studies in animal models...

Cancer cachexia is defined as a state of involuntary weight loss, attributed to altered body composition with muscle mass loss and/or loss of adiposity. Identifying the association between cancer cachexia and outcomes may pave the way for novel agents that target the cancer cachexia process. Clinical parameters for measurement of cancer cachexia are needed. We conducted a single-institution retrospective analysis that included 86 NHL patients with the aim of identifying an association between cancer cachexia and outcomes in aggressive lymphomas using the cachexia index (CXI) suggested by Jafri et al...

BACKGROUND: Chronic kidney disease is a common condition in the general population, particularly among older adults. Renal impairment is in turn associated with metabolic and nutritional derangements and with increased risk of cardiovascular disease. AIM: To compare the metabolic, nutritional, and cardiovascular impact of reduced kidney function between patients with and without known renal disease. MATERIALS AND METHODS: We enrolled consecutive outpatients (age ≥65 years) with reduced renal function who were divided into two groups: Group A with history of renal disease and Group B with unknown renal disease...

BACKGROUNDS AND AIMS: Involuntary weight loss and muscle mass loss among HIV-positive patients are only detectable in late stages, leading poor life quality. The reduction of adductor pollicis muscle thickness (APMT) can be easily and earlier uncovered in those cases. The purpose was to estimate APMT and compare it with immunological and anthropometric parameters of HIV-infected people. METHODS: A crosssectional study was carried out in an University Hospital including 103 HIV-infected outpatients by subjective global assessment (SGA)...

INTRODUCTION: Long-term adverse symptoms of men who used oral finasteride against androgenic alopecia have been recently described as post-finasteride syndrome (PFS). AIM: To determine whether (CAG)n-rs4045402 and (GGN)n-rs3138869 polymorphisms in the androgen receptor (AR) gene are implicated in PFS. METHODS: AR polymorphisms were studied according to PFS symptoms in 66 white participants (31.8% Italian, 28.8% American, and 39.4% other). MAIN OUTCOME MEASURES: Symptoms were investigated by an ad hoc 100-item questionnaire and the Arizona Sexual Experience Scale and Aging Male Symptom Scale (AMS)...

Background. Undernutrition and major depressive disorder are frequently co-occurring. Patients with impaired mental health are strongly vulnerable to the risks of having involuntary weight loss or deficiency of essential nutrients. However, there is no study which assesses undernutrition among major depressive patients in Ethiopia. Method. A total of 422 clients were included in the study. Structured questionnaires and anthropometric measurements were used for collecting the data. Bivariate and multivariate logistic regression model was fitted to identify factors associated with undernutrition...

BACKGROUND: In 2015 the European Society for Clinical Nutrition and Metabolism (ESPEN) presented new consensus criteria for the diagnosis of malnutrition. Whereas most previous definitions were based on involuntary weight loss and/or a low BMI, the ESPEN definition added Fat Free Mass Index (FFMI) to the set of criteria. AIM: To study the predictive value of the new ESPEN diagnostic criteria for malnutrition on survival, with specific focus on the additional value of FFMI...

OBJECTIVE: Cancer cachexia is a paraneoplastic syndrome comprising involuntary weight loss and muscle depletion (sarcopenia). Although weight loss has been associated with poor clinical outcome, there is only limited information on the prevalence and prognostic impact of sarcopenia in ovarian cancer so far. METHODS: Total skeletal muscle mass was determined by computed tomography image analysis of the third lumbar skeletal muscle cross-sectional area in 128 patients with advanced serous ovarian cancer...

Involuntary weight loss, a part of the cachexia syndrome, is a debilitating comorbidity of cancer and currently has no treatment options. Results from a recent clinical trial at our institution showed that biliary tract cancer patients treated with a MEK inhibitor exhibited poor tumor responses but surprisingly gained weight and increased their skeletal muscle mass. This implied that MEK inhibition might be anticachectic. To test this potential effect of MEK inhibition, we utilized the established Colon-26 model of cancer cachexia and the MEK1/2 inhibitor MEK162...

Celiac disease is the most important cause of intestinal villous atrophy. Seronegative intestinal villous atrophy, including those that are nonresponsive to a gluten-free diet, is a diagnostic challenge. In these cases, before establishing the diagnosis of seronegative celiac disease, alternative etiologies of atrophic enteropathy should be considered. Recently, a new clinical entity responsible for seronegative villous atrophy was described-olmesartan-induced sprue-like enteropathy. Herein, we report two uncommon cases of atrophic enteropathy in patients with arterial hypertension under olmesartan, who presented with severe chronic diarrhea and significant involuntary weight loss...

Huntington's disease (HD) is an inherited progressive neurodegenerative disorder associated with involuntary abnormal movements (chorea), cognitive deficits and psychiatric disturbances. The most striking neuropathological change in HD is the early atrophy of the striatum. While the disease progresses, other brain structures also degenerate, including the cerebral cortex. Changes are also seen outside the brain, in particular weight loss/cachexia despite high dietary intake. The disease is caused by an abnormal expansion of a CAG repeat in the gene encoding the huntingtin protein (Htt)...

OBJECTIVES: Muscle wasting in patients with cancer has been linked to an increased activity of nuclear factor κB (NF-κB) and higher circulating levels of activin-A (ActA), a negative growth factor for muscle mass. Baicalin is a natural flavonoid that can reduce skeletal muscle atrophy in animal models of cancer cachexia by inhibiting NF-κB. This pilot open-label study assessed the effects of baicalin supplementation (50 mg daily for 3 months) in cancer patients who showed involuntary weight loss >5% over the past 6 months...

We describe a 43-year-old patient with subacute appearance of neurological and atypical complaints of anergia, anorexia and weight loss six months earlier. In spite of several admissions in different hospitals, no underlying somatic cause could be found and he was admitted to a psychiatric hospital with a tentative diagnosis of major depressive disorder. Subsequently, he was referred to the unit of medically unexplained physical symptoms within the department of general internal medicine for assessment by the psychiatrist, involved in this programme...

REVIEW
Richard Charnigo, Maya Guglin
The "obesity paradox" in heart failure (HF) is a phenomenon of more favorable prognosis, especially better survival, in obese versus normal-weight HF patients. Various explanations for the paradox have been offered; while different in their details, they typically share the premise that obesity per se is not actually the cause of reduced mortality in HF. Even so, there is a lingering question of whether clinicians should refrain from, or at least soft-pedal on, encouraging weight loss among their obese HF patients...
