OBJECTIVES: To test the potential efficacy of recombinant macrophage inhibitory cytokine-1 (MIC-1/GDF15) as an obesity therapeutic. METHODS: Male C57BL/6J mice, either fed on normal-chow or high-fat-diet for 16 weeks in order to induce diet-induced obesity, were infused with either recombinant MIC-1/GDF15 or vehicle for 34 days by osmotic-mini-pump. During the experimental period metabolic parameters were measured. Blood and tissue were collected for analysis of inflammatory markers...

Modern lifestyle factors (high-caloric food rich in fat) and daily chronic stress are important risk factors for metabolic disturbances. Increased hypothalamic-pituitary-adrenal (HPA) axis activity and the subsequent excess production of glucocorticoids (GCs) in response to chronic stress (CS) leads to increases in metabolic complications, such as type 2 diabetes and insulin resistance (IR). Melatonin (MLT), which protects several regulatory components of the HPA axis from GC-induced deterioration, might improve glucose homeostasis...

BACKGROUND: Patients with irritable bowel syndrome (IBS) are often placed on diets guided by food intolerance assays, although these have not been validated. We assessed the effects of individualised diets in patients with IBS guided by a leucocyte activation test. METHODS: This is a parallel-group, double-blind, randomised controlled trial of 58 adults with IBS seen at an academic health centre in Northeast USA. Peripheral venous blood was analysed using a leucocyte activation test; individual foods were reported to produce positive or negative results...

PURPOSE OF REVIEW: Human exposure to wheat and milk is almost global worldwide. Yet the introduction of milk and wheat is very recent (5000-10 000 years) when compared to the human evolution. The last 4 decades have seen a rise in food allergy and food intolerance to milk and wheat. Often described as plurifactorial, the cause of allergic diseases is the result from an interplay between genetic predisposition and epigenetic in the context of environmental changes. RECENT FINDINGS: Genetic and epigenetic understanding and their contribution to allergy or other antigen-driven diseases have considerably advanced in the last few years...

Previous studies have shown that leptin resistance is a key feature that leads to gestational metabolic adaptions. We hypothesized that leptin sensitivity in the ventromedial nucleus of the hypothalamus (VMH) plays a critical role regulating gestational metabolic changes. In the present study, we generated a mouse model carrying ablation of the suppressor of cytokine signaling 3 (SOCS3) in steroidogenic factor-1 (SF1) cells, which include the VMH, in order to investigate whether increased leptin sensitivity in this neuronal population prevents at least part of the metabolic changes typically observed during gestation and lactation...

Despite the occurrence of dyslipidemia and its contribution to the development of insulin resistance in obese subjects, a growing number of studies have described abnormal lipid profiles among leaner persons. For example, individuals with an abnormal paucity or distribution of fat (lipodystrophy) develop severe insulin resistance, dyslipidemia, and hepatic steatosis. Deranged adipocyte metabolism and differentiation contribute to ectopic fat deposition and consequent development of insulin resistance. Growth hormone (GH) therapy has been shown to correct body composition abnormalities in some lipodystrophy patients...

Melkersson-Rosenthal Syndrome (MRS) is a rare disorder consisting of a triad of persistent or recurrent orofacial edema, relapsing facial paralysis and fissured tongue. It is rarely possible to observe all aspects of the classical triad at the same time, since these symptoms may appear in different times of life cycle. The most common symptom is orofacial edema. Although etiology of MRS is unclear, various factors such as infections, genetic predisposition, immune deficiency, food intolerance and stress have been held responsible...

BACKGROUND: With the introduction of avoidant/restrictive food intake disorder (ARFID) in the Diagnostic and Statistical Manual - fifth edition, there is an increased need to understand the prevalence and pattern of food avoidance and restriction in adults. High rates of food allergy and intolerance in immunology clinic populations, and subsequent high rates of elimination diets, place these individuals at a greater risk of developing pathological eating behaviours. This descriptive cross sectional pilot study aims to provide preliminary data on the prevalence and nature of food avoidance and restriction in an adult population, and to explore the reasons for this behaviour...

BACKGROUND: To examine the effect and mechanism of Roux-en-Y gastric bypass (RYGB) on the improvement of diabetes according to the length of anastomosis and the gastric pouch volume in an animal model. METHODS: Glucose intolerance was induced with a high-fat diet for 3 months in Sprague-Dawley rats. The animals were subjected to conventional RYGB (cRYGB; 5% gastric pouch with 15-cm Roux limb, 40-cm biliopancreatic limb; n = 9), short-limb RYGB (sRYGB; 5%, 8, 4 cm; n = 9), fundus-sparing RYGB (fRYGB; 30%, 8, 4 cm; n = 9), or sham operation (n = 9)...

BACKGROUND: Exposure to ambient fine particulate matter (PM2.5) is associated with increased cardiometabolic morbidity and mortality. This is widely believed to be attributable to PM2.5 exposure-induced pulmonary and subsequent systemic inflammation. Tumor necrosis factor alpha (TNFα), lymphotoxin α (LTα), and lymphotoxin β (LTβ) are three homologous pro-inflammatory cytokines, each with both unique and redundant activities in inflammation. Their role in PM2.5 exposure-induced inflammation and adverse cardiometabolic effects has to be determined...

BACKGROUND AND OBJECTIVES: Reasons for intolerance to commercial amino acid-based formulas (cAAF) in infants diagnosed with cow's milk protein allergy (CMA) remain unknown. We assume that minute amounts of proteins, presenting in the glucose polymers derived from corn starch (cGPs), can elicit the intolerance to the cAAFs observed in some infants with CMA. By replacing cGPs with glucose polymers derived from rice starch (rGPs), a new amino acid-based (nAAF) formula has been shown to be better tolerated than an existing cAAF...

Ghrelin secretion has been associated with increased caloric intake and adiposity. The expressions of ghrelin and its receptor (GHS-R1a) in pancreas have raised the interest about the role of ghrelin in glucose homeostasis. Most of the studies showed that ghrelin promoted hyperglycaemia and inhibited insulin secretion. This raised the interest in using GHS-R1a antagonists as therapeutic targets for type 2 diabetes. Available data of GHS-R antagonists are on a short-term basis. Moreover, the complexity of GHS-R1a signalling makes it difficult to understand the mechanism of action of GHS-R1a antagonists...

BACKGROUND: Many food items have been involved in gastro-esophageal reflux disease pathogenesis and dietary modification has been proposed as first-line treatment. Test-based exclusion diets have shown to significantly reduce reflux symptoms. we aimed to assess the patterns of food intolerance in a series of patients with typical gastro-esophageal reflux symptoms (GERS). METHODS: We retrospectively evaluated all patients with typical reflux symptoms, attending the Centre Study Association on Food Intolerance and Nutrition of Ferrara from January 2010 to October 2015, who resulted positive to at least one food item at the leucocytotoxic test...

The brain-specific isoform of renin (Ren-b) has been proposed as a negative regulator of the brain renin-angiotensin system (RAS). We analyzed mice with a selective deletion of Ren-b which preserved expression of the classical renin (Ren-a) isoform. We reported that Ren-b(Null) mice exhibited central RAS activation and hypertension through increased expression of Ren-a, but the dipsogenic and metabolic effects in Ren-b(Null) mice are unknown. Fluid intake was similar in control and Ren-b(Null) mice at baseline and both exhibited an equivalent dipsogenic response to deoxycorticosterone acetate-salt...

There is broad anthropological interest in understanding how people define "insiders" and "outsiders" and how this shapes their attitudes and behaviors toward others. As such, a suite of hypotheses has been proposed to account for the varying degrees of in-group preference between individuals and societies. We test three hypotheses related to material insecurity, pathogen stress, and views of gender equality among cross-sectional (n = 1896) and longitudinal (n = 1002) samples of young people in Ethiopia (aged 13-17 years at baseline) to explore stability and change in their preferences for coethnic spouses...

Inflammatory bowel diseases (IBD) represent a growing public health concern due to increasing incidence worldwide. The current notion on the pathogenesis of IBD is that genetically susceptible individuals develop intolerance to dysregulated gut microflora (dysbiosis) and chronic inflammation develops as a result of environmental triggers. Among the environmental factors associated with IBD, diet plays an important role in modulating the gut microbiome, influencing epigenetic changes, and, therefore, could be applied as a therapeutic tool to improve the disease course...

Food allergies and food intolerances are clinically difficult to discriminate. Most often, along with cutaneous adverse food reactions or CAFR, they are classified as adverse food reactions, whose causes are numerous, including toxic compounds. Eighteen indoor-housed domestic cats with evident clinical symptoms related to CAFR (drooling, back and neck intense itching, neck eczema, chronic conjunctivitis and stomatitis) involving skin lesions were studied. Cytological evaluations of ear, skin and gingival swabs revealed an increased turnover of keratinocytes while the oxytetracycline ELISA determination showed an unexpected high amount of oxytetracycline in all cats at the first visit...

REVIEW
Manan A Jhaveri, Kris V Kowdley
Primary biliary cholangitis (PBC) is a chronic autoimmune cholestatic liver disease that predominantly affects women in early to middle age. It is typically associated with autoantibodies to mitochondrial antigens and results in immune-mediated destruction of small and medium-sized intrahepatic bile ducts leading to cholestasis, hepatic fibrosis and may progress to cirrhosis or hepatic failure and, in some cases, hepatocellular carcinoma. The clinical presentation and the natural history of PBC have improved over the years due to recognition of earlier widespread use of ursodeoxycholic acid (UDCA); about one-third of patients show suboptimal biochemical response to UDCA with poor prognosis...

Among the wheat prolamins important for its end-use traits, α-gliadins are the most abundant and also a major cause of food-related allergies and intolerances. Previous studies of various wheat species estimated between 25 to 150 α-gliadin genes reside in the Gli-2 locus regions. To better understand the evolution of this complex gene family, the DNA sequence of a 1.75-Mb genomic region spanning the Gli-2 locus was analyzed in the diploid grass, Aegilops tauschii, the ancestral source of D genome in hexaploid bread wheat...
