REVIEW
Graham Finlayson
The concept of addiction is loaded with connotations and is often used for its political as much as its medical utility. The scientific case for 'food addiction' as a clinical phenotype currently rests on its association with generic diagnostic criteria for substance-related disorders being applied to everyday foods and eating-related problems. This has fused the concept of obesity with addiction regardless of whether it fits the definition. The hedonic, or reward, system can account for the ingestion of foods and drugs, confirming that they share neural substrates that differentiate liking and wanting...

OBJECTIVE: Eudaemonic positive psychological health (PPH), such as purpose in life (PIL), may be maintained more than hedonic PPH, such as quality of life (QOL), for patients with amyotrophic lateral sclerosis (ALS) and their caregivers across the disease course. Furthermore, patients' and caregivers' PPH may impact one another. The present study examined (a) PIL and QOL variance structures; (b) PIL and QOL trajectories from diagnosis, approaching death, with disease severity; and (c) between-dyad and within-dyad relationships for PIL and QOL in patients with ALS and their caregivers...

Cumulative evidence suggests that trait rumination can be defined as an abstract information processing mode, which leads people to constantly anticipate the likely impact of present events on future events and experiences. A previous study with remitted depressed patients suggested that enhanced rumination tendencies distort brain mechanisms of anticipatory processes associated with reward and loss cues. In the present study, we explored the impact of trait rumination on neural activity during reward and loss anticipation among never-depressed people...

The hedonic component of the feeding behavior involves the mesolimbic reward system and resembles addictions. Nowadays, the excessive consumption of sucrose is considered addictive. The Wistar-Kyoto (WKY) rat strain is prone to develop anxiety and addiction-like behavior; nevertheless, a lack of information regarding their vulnerability to develop sugar binging-like behavior (SBLB) and how it affects the reward system persist. Therefore, the first aim of the present study was to compare the different predisposition of two rat strains, Wistar (W) and WKY to develop the SBLB in female and male rats...

AIMS/HYPOTHESIS: Overeating of dietary fats causes obesity in humans and rodents. Recent studies in humans and rodents have demonstrated that addiction to fats shares a common mechanism with addiction to alcohol, nicotine and narcotics in terms of a dysfunction of brain reward systems. It has been highlighted that a high-fat diet (HFD) attenuates dopamine D2 receptor (D2R) signalling in the striatum, a pivotal regulator of the brain reward system, resulting in hedonic overeating. We previously reported that the brown rice-specific bioactive constituent γ-oryzanol attenuated the preference for an HFD via hypothalamic control...

Depression induced by stress is affected by sex, age and hormonal status of the animal and also by duration and type of the stressors. Moreover, higher prevalence of depression and comorbidities in women than men implies the need to include the sex variable in studies on animal models of depression. The present study was therefore initiated to evaluate the effect of sex and ovarian hormones on depression-like phenotypes in mice exposed to a 21-day Chronic Variable Mild Stress (CVMS) paradigm. Adult male, intact female and, ovariectomized (OVX) female mice exposed to CVMS displayed despair behavior, a depression-like phenotype, in all the groups...

In recent years, different chlorhexidine formulations have been tested, including an alcohol-free alternative, but the effect of this solution on early biofilm formation is not clear. A crossover, randomized, double-blind clinical trial was conducted to evaluate the effect of two chlorhexidine solutions against supra- and subgingival biofilm formation (NCT#02656251). Thirty-five participants were randomized and asked to rinse twice daily with 15 ml of an alcohol-containing 0.12% chlorhexidine solution, an alcohol-free 0...

Main factors that are considered by consumers when choosing meat products are colour and aroma, of which the latter is a more reliable indicator of quality. However, a simple sensory evaluation of hedonistic qualities is often not sufficient to determine whether protein is past its shelf life, and consumption of spoiled meat can lead to serious health hazards. Some volatile compounds can be used as spoilage indicators, and so a device equipped with a sensor sensitive to particular odorants would prove useful...

OBJECTIVE: Roux-en-Y gastric bypass (RYGB) surgery reduces appetite and stimulates new onset alcohol misuse; however, the genesis of these behavioral changes is unclear. This study is hypothesized that new onset alcohol intake is a behavioral adaptation that occurs secondary to reduced appetite and correlates with altered central ghrelin signaling. METHODS: Hedonic high-fat diet (HFD) intake was evaluated prior to the assessment of alcohol intake behaviors in RYGB and control rats...

BACKGROUND: Heart failure (HF) disproportionately afflicts older adults. Dietary sodium indiscretion is frequently implicated in HF decompensation. The affinity for and ability to taste salt in this process is unexplored. We sought to evaluate differences in salt taste by age and HF diagnosis and to map changes following hospitalization for acute decompensated heart failure (ADHF). METHODS: Seventy-two subjects underwent initial salt-taste testing during hospitalization for ADHF...

OBJECTIVE: To determine how visceral sensations affect responses to food stimuli in anorexia nervosa (AN). METHODS: Twenty weight-restored, unmedicated adolescent and young adult women with AN and twenty healthy control participants completed an interoceptive attention task during which they focused on sensations from the heart, stomach, and bladder and made ratings of these sensations. They then underwent fMRI scanning while viewing pictures of food and non-food objects...

BACKGROUND: Use of nonnutritive sweeteners (NNSs), which provide sweet taste with few to no calories, has increased, but data on whether children's hedonic responses to NNSs differ from nutritive sugars or from adults' hedonic responses are limited. METHODS: Most preferred levels of sucrose and the NNS sucralose were determined via a forced-choice tracking procedure in 48 children, 7-14 years (mean = 10 years), and 34 adults. Each participant also rated the liking of these taste stimuli, as well as varying concentrations of aspartame on 3- and 5-point facial hedonic scales...

A series of studies investigated the effects of hedonic content, brightness, and contrast on pupil diameter during free viewing of natural scenes, assessing the amplitude of the initial light reflex and subsequent sustained pupil diameter change. Hedonic picture content varied from highly arousing scenes of erotica and violence to scenes depicting nature, babies, loss, contamination, food, and more. Despite equivalent overall picture brightness and contrast, pupil diameter still varied as a function of the local brightness of central vision at fixation...

Pairing a taste with either internal pain (e.g., from hypertonic saline injection) or nausea (e.g., from LiCl administration) will reduce subsequent consumption of that taste. Here we examine the responses to a taste paired with either hypertonic saline or LiCl using the analysis of licking microstructure (mean lick cluster size: Experiments 1-3), taste reactivity (examining the distribution of appetitive and aversive orofacial responses: Experiments 2-3), and immobility (as a measure of fear: Experiments 2-3)...
