Abstract
There are numerous pieces of evidence indicating that moderate alcohol intake has a protective effect on metabolic diseases. Our previous studies revealed that long-term low-dose alcohol intake resists high-fat diet (HFD) induced obesity. A process in which white adipose tissue can be stimulated and turned into heat-producing brown adipose tissue named white adipose browning is associated with energy expenditure and weight loss. In this study we aimed to investigate whether alcohol causes the browning of white adipose tissue and whether the browning of white adipose tissue is involved in the resistance to the occurrence of obesity caused by long-term low-dose alcohol intake. After eight months of alcohol feeding, the body weight of mice had no significant change, but the fat content and lipid deposition in the liver were reduced. Morphological observations revealed that the browning of white adipose tissue occurred. The white adipose tissue browning marker UCP1 gene and protein expression levels were increased and the expression of the PGC1-α/PPAR-α pathway protein and the P38 MAPK/CREB pathway protein was also elevated in the alcohol feeding group. Moderate alcohol drinking increased the secretion of the CXCL14 protein in inguinal subcutaneous adipose tissue, which drove the recruitment of M2 macrophages. Moderate alcohol drinking mice had faster lipid metabolism and slower lipid anabolism. In addition, we found that long-term low-dose alcohol intake prevented the increase of body weight, triglycerides, inflammation and energy expenditure decrease induced by HFD. Moderate alcohol consumption increased the expression of UCP1 and glucose uptake in the adipose tissue of the HFD group. In conclusion, our results show for the first time that alcohol can trigger the browning of white adipose tissue to counteract obesity.

C-reactive protein is related to a distinct set of alterations in resting-state functional connectivity contributing to a differential pathophysiology of major depressive disorder. Psychiatry Res Neuroimaging 2022; 321:111440. [PMID: 35131572 DOI: 10.1016/j.pscychresns.2022.111440] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 12/10/2021] [Accepted: 01/18/2022] [Indexed: 01/23/2023]
Abstract
BACKGROUND Several studies in major depressive disorder (MDD) have found inflammation, especially C-reactive protein (CRP), to be consistently associated with MDD and network dysfunction. The aim was to investigate whether CRP is linked to a distinct set of resting-state functional connectivity (RSFC) alterations. METHODS For this reason, we investigated the effects of diagnosis and elevated blood plasma CRP levels on the RSFC in 63 participants (40 females, mean age 31.4 years) of which were 27 patients with a primary diagnosis of MDD and 36 healthy control-subjects (HC), utilizing a seed-based approach within five well-established RSFC networks obtained using fMRI. RESULTS Of the ten network pairs examined, five showed increased between-network RSFC-values unambiguously connected either to a diagnosis of MDD or elevated CRP levels. For elevated CRP levels, increased RSFC between DMN and AN was found. Patients showed increased RSFC within DMN areas and between the DMN and ECN and VAN, ECN and AN and AN and DAN. CONCLUSIONS The results of this study show dysregulated neural circuits specifically connected to elevated plasma CRP levels and independent of other alterations of RSFC in MDD. This dysfunction in neural circuits might in turn result in a certain immune-inflammatory subtype of MDD.

Abstract
OBJECTIVES Many studies have established a relationship between diet and mental health, as well as the importance of bowel health. Further, with increased evidence of a gut-brain bidirectional relationship, an indication of dysbiosis as a potential moderator between diet and depression may be a viable target for future interventions. The current study investigated the relationship between diet and depressive symptoms (DS) among older adults, as well as gender, and whether a symptom of dysbiosis, fecal incontinence severity (FIS), moderated this relationship. METHOD Using moderated regressions, we examined whether FIS moderates the relationship between diet and DS while controlling for covariates in the overall sample (N = 1918), as well as among the male (n = 841) and female sample (n = 1077). The dietary variables were reduced using a factor analysis. RESULTS Results indicated significant moderating effects of FIS between Component 4 and polyunsaturated fatty acids (PFA) in the overall sample. Component 4, protein, carbohydrates, and alcohol were significant in males only while PFA only in females. Further analysis of protein/carbohydrate ratio groups indicated significant differences within males. Higher scores of FIS were related to higher DS and less consumption of Component 4 nutrients, PFA, and protein. Males that consumed higher protein and carbohydrates resulted in lower DS with increased FIS. CONCLUSION Outcomes from the current study provide further evidence of the importance of healthy bowel function and the potential of modifying the diet to improve DS in older adults.

The Relation of Light-to-Moderate Alcohol Consumption to Glucose Metabolism and Insulin Resistance in Nondiabetic Adults: the Moderating Effects of Depressive Symptom Severity, Adiposity, and Sex. Int J Behav Med 2018; 24:927-936.

Abstract
PURPOSE We examined the relation of alcohol consumption to glucose metabolism and insulin resistance (IR) as a function of depressive symptoms, adiposity, and sex. METHOD Healthy adults (aged 18-65 years) provided fasting blood samples and information on lifestyle factors. Alcohol intake was categorized as never, infrequent (1-3 drinks/month), occasional (1-7 drinks/week), and regular (≥2 drinks/day) drinkers. The Beck Depression Inventory (BDI) was used to assess symptom severity. Primary outcomes were fasting insulin, glucose, and IR assessed by the homeostasis model assessment (HOMA). RESULTS In univariate analysis, alcohol consumption was negatively associated with HOMA-IR (p = 0.03), insulin (p = 0.007), and body mass index (BMI) (p = 0.04), but not with glucose or BDI. Adjusting for potential confounders including BMI, alcohol consumption was associated with HOMA-IR (p = 0.01) and insulin (p = 0.009) as a function of BDI and sex. For women with minimal depressive symptoms, light-to-moderate alcohol consumption was associated with lower HOMA-IR and insulin. Alcohol consumption was not associated with metabolic markers in women with higher depressive symptoms and in men. In analysis using BMI as a continuous moderator, alcohol consumption was only associated with insulin (p = 0.004). Post-hoc comparisons between BMI groups (<25 vs ≥25 kg/m2) revealed that light-to-moderate alcohol consumption was associated with lower insulin but only in subjects with BMI ≥ 25 kg/m2. CONCLUSIONS The benefits of light-to-moderate alcohol consumption on fasting insulin and IR are sex dimorphic and appear to be independently moderated by adiposity and depressive symptom severity.

Abstract
BACKGROUND AND OBJECTIVES Previous literature using small sample sizes and limited geographic areas report that overweight/obesity and physical inactivity occur at higher rates among children with autism spectrum disorder (ASD) compared to typically developing peers. The purpose of this study was to examine obesity, overweight, physical activity, and sedentary behavior among children and youth with and without ASD using nationally representative data and controlling for secondary conditions, including intellectual and learning disabilities, ADHD, developmental delay, and other mental, physical, and medical conditions, as well as medication use. METHODS Data were collected from the 2011-2012 National Survey of Children's Health, a cross-sectional survey of 65,680 (weighted N = 49,586,134) children aged 6-17 (1385 with ASD, weighted N = 986,352). Logistic regression was used to estimate odds ratios, adjusting for demographics and possible secondary conditions. RESULTS Having a diagnosis of ASD was associated with higher odds of obesity (OR 1.76, CI 1.27-2.43; p = <0.001). However, after additional adjustment for possible secondary conditions, ASD diagnosis was no longer associated with obesity. Those with moderate ASD (OR 0.58, CI 0.36-0.93; p = <0.05) reported lower odds of sedentary behavior, but this association failed to achieve significance after adjustment for secondary conditions and medication use. No significant associations between ASD and overweight or physical activity were found. CONCLUSIONS These findings suggest that ASD diagnosis is not significantly associated with obesity status after adjustment for possible secondary conditions and medication use. Decision makers, clinicians, and researchers developing interventions for children with ASDs should consider how secondary conditions may impact obesity and related activities.

Abstract
PURPOSE Evidence on the association between psychological well-being and high-sensitivity C-reactive protein (hs-CRP) levels is limited. We carried out a prospective study to investigate the association between work engagement and hs-CRP levels in a group of Japanese workers. METHODS Our cohort included 1,857 men and 657 women aged 65 and under, and free from major illness, working at two manufacturing worksites in Japan. Baseline examinations were conducted from April to June 2011 to determine the demographic and lifestyle characteristics and levels of work engagement. Blood samples were obtained from participants at baseline and after 1 year. Participants were classified into tertiles of low, moderate, and high work engagement at baseline. Hs-CRP levels were split into low (≤3.0 mg/L) and high (>3.0 mg/L). We used multiple logistic regression analyses to evaluate the association between work engagement at baseline and hs-CRP levels at follow-up, adjusting for hs-CRP at baseline and potential confounding factors. RESULTS Participants reporting moderate and high levels of work engagement at baseline had significantly lower odds ratios (ORs) of having high hs-CRP levels at follow-up than those with low levels of work engagement at baseline [OR of moderate level 0.44, 95% confidence interval (CI) 0.24-0.81; OR of high level 0.57, 95% CI 0.33-0.99; p for trend <0.05]. CONCLUSION Findings suggest that work engagement has beneficial effects on workers' cardiovascular health.

Abstract
BACKGROUND Adults who suffer from psychiatric disorders report low levels of physical activity and the activity levels differ between disorders. Less is known regarding physical activity across psychiatric disorders in adolescence. We investigate the frequency and type of physical activity in adolescent psychiatric patients, compared with adolescents in the general population. METHODS A total of 566 adolescent psychiatric patients aged 13-18 years who participated in the CAP survey, Norway, were compared to 8173 adolescents aged 13-19 years who participated in the Nord-Trøndelag Health Study, Young-HUNT 3, Norway. All adolescents completed a questionnaire, including questions about physical activity and participation in team and individual sports. RESULTS Approximately 50% of adolescents with psychiatric disorders and 25% of the population sample reported low levels of physical activity. Within the clinical sample, those with mood disorders (62%) and autism spectrum disorders (56%) were the most inactive and those with eating disorders (36%) the most active. This pattern was the same in individual and team sports. After multivariable adjustment, adolescents with a psychiatric disorder had a three-fold increased risk of lower levels of physical activity, and a corresponding risk of not participating in team and individual sports compared with adolescents in the general population. CONCLUSIONS Levels of physical activity were low in adolescent psychiatric patients compared with the general population, yet activity levels differed considerably between various disorders. The findings underscore the importance of assessing physical activity in adolescents with psychiatric disorders and providing early intervention to promote mental as well as physical health in this early stage of life.

Abstract
The purposeful application of fermentation in food and beverage preparation, as a means to provide palatability, nutritional value, preservative, and medicinal properties, is an ancient practice. Fermented foods and beverages continue to make a significant contribution to the overall patterns of traditional dietary practices. As our knowledge of the human microbiome increases, including its connection to mental health (for example, anxiety and depression), it is becoming increasingly clear that there are untold connections between our resident microbes and many aspects of physiology. Of relevance to this research are new findings concerning the ways in which fermentation alters dietary items pre-consumption, and in turn, the ways in which fermentation-enriched chemicals (for example, lactoferrin, bioactive peptides) and newly formed phytochemicals (for example, unique flavonoids) may act upon our own intestinal microbiota profile. Here, we argue that the consumption of fermented foods may be particularly relevant to the emerging research linking traditional dietary practices and positive mental health. The extent to which traditional dietary items may mitigate inflammation and oxidative stress may be controlled, at least to some degree, by microbiota. It is our contention that properly controlled fermentation may often amplify the specific nutrient and phytochemical content of foods, the ultimate value of which may associated with mental health; furthermore, we also argue that the microbes (for example, Lactobacillus and Bifidobacteria species) associated with fermented foods may also influence brain health via direct and indirect pathways.
