Neurotrophins, particularly, NGF and BDNF are now well recognized to mediate a dizzying number of trophobiological effects, ranging from the Rita Levi-Montalcini's neurotrophic through immunotrophic to metabotrophic effects.These are implicated in the pathogenesis of various diseases including neuropsychiatric and cardiometabolic diseases, such as dementia, depression, type 2 diabetes and obesity that may express a common phenotype and coexistence. Recently, adipobiology (adiposcience) as become a focus of numerous studies showing that the adipose tissue is the body's largest endocrine organ producing multiple signaling proteins, including NGF and BDNF, all these dubbed adipokines. On the basis of our and other authors' evidence that low NGF and/or BDNF levels are found in cardiometabolic diseases (atherosclerosis, obesity, type 2 diabetes, metabolic syndrome), a hypothesis of a critical role of neuro-metabotrophic deficit in the pathogenesis of these diseases has been raised. Since NGF and BDNF also exerts various synaptotrophic effects involved in cognitive enhancement, this hypothesis might also be related to neuropsychiatric diseases such as dementia, depression, schizophrenia, autism, Rett syndrome, anorexia nervosa, and bulimia nervosa. Finally, NGF- and BDNF-based therapeutic approach, including ampakines, antidepressants, selective deacetylase inhibitors, statins, peroxisome proliferator-activated receptor gamma agonists, and "brain food" and calorie restriction, is outlined.

Ghrelin is a brain-gut peptide that was discovered through reverse pharmacology and was first isolated from extracts of porcine stomach. Ghrelin binds to growth hormone secretagogue receptor (GHS-R) and is acylated on its serine 3 residue by ghrelin O-acyltransferase (GOAT). Several important biological functions of ghrelin have been identified, which include its growth hormone-releasing and appetite-inducing effects. Ghrelin exerts its central orexigenic effect mainly by acting on the hypothalamic arcuate nucleus via the activation of the GHS-R. Peripherally ghrelin has multiple metabolic effects which include promoting gluconeogenesis and fat deposition. These effects together with the increased food intake lead to an overall body weight gain. AMP-activated protein kinase, which is a key enzyme in energy homeostasis, has been shown to mediate the central and peripheral metabolic effects of ghrelin. The hypothalamic fatty acid pathway, hypothalamic mitochondrial respiration and uncoupling protein 2 have all been shown to act as the downstream targets of AMPK in mediating the orexigenic effects of ghrelin. Abnormal levels of ghrelin are associated with several metabolic conditions such as obesity, type 2 diabetes, Prader-Willi syndrome and anorexia nervosa. The ghrelin/GOAT/GHS-R system is now recognised as a potential target for the development of anti-obesity treatment.

Bone strength is affected not only by bone mineral density (BMD) and bone microarchitecture but also its microenvironment. Recent studies have focused on the role of marrow adipose tissue (MAT) in the pathogenesis of bone loss. Osteoblasts and adipocytes arise from a common mesenchymal stem cell within bone marrow and many osteoporotic states, including aging, medication use, immobility, over - and undernutrition are associated with increased marrow adiposity. Advancements in imaging technology allow the non-invasive quantification of MAT. This article will review magnetic resonance imaging (MRI)- and computed tomography (CT)-based imaging technologies to assess the amount and composition of MAT. The techniques that will be discussed are anatomic T1-weighted MRI, water-fat imaging, proton MR spectroscopy, single energy CT and dual energy CT. Clinical applications of MRI and CT techniques to determine the role of MAT in patients with obesity, anorexia nervosa, and type 2 diabetes will be reviewed.

BACKGROUND Little has been reported regarding the epidemiology of eating disorders (EDs) in type 2 diabetes (T2DM). We examined the Polish National Health Fund-NFZ database estimates of all medical visits from 2008 to 2017 to determine the trend and the epidemiology of EDs in T2DM patients. MATERIAL AND METHODS The NFZ database were used. We defined the T2DM group diagnosed with both T2DM and EDs according to the ICD-10 codes. Demographic data were collected from the webpage of Statistics Poland (GUS). The annual prevalence of EDs was estimated according to the T2DM diagnosis status, and the age groups were stratified into 8 groups. RESULTS The prevalence of EDs in T2DM patients in the whole patient population with diagnosed T2DM ranged from 0.059% (in 2017) to 0.086% patients (in 2010). Differences in subcategories of EDs were noted. In the case of anorexia nervosa, a decreasing trend of coexistence with T2DM was noted. However, in the case of atypical anorexia nervosa, an increasing trend was observed. Both in the case of bulimia nervosa and atypical bulimia nervosa, an increasing trend of coexistence with T2DM was noted. As patients with T2DM age, the prevalence of EDs in T2DM decreased. CONCLUSIONS A relatively stable trend of prevalence of EDs in T2DM patients benefiting from state medical care indicated the need to develop effective screening methods and adequate procedures for therapeutic interventions with this group of patients using a multidisciplinary therapeutic team.

Ghrelin is a gastric hormone with multiple physiological functions, including the stimulation of food intake and adiposity. It is well established that circulating ghrelin levels are closely associated with feeding patterns, rising strongly before a meal and lowering upon food intake. However, the mechanisms underlying the modulation of ghrelin secretion are not fully understood. The purpose of this review is to discuss current knowledge on the circadian oscillation of circulating ghrelin levels, the neural mechanisms stimulating fasting ghrelin levels and peripheral mechanisms modulating postprandial ghrelin levels. Furthermore, the therapeutic potential of targeting the ghrelin pathway is discussed in the context of the treatment of various metabolic disorders, including obesity, type 2 diabetes, diabetic gastroparesis and Prader-Willi syndrome. Moreover, eating disorders including anorexia nervosa, bulimia nervosa and binge-eating disorder are also discussed.
