Neurosci Biobehav Rev 2024; 164:105785. [PMID: 38945418 DOI: 10.1016/j.neubiorev.2024.105785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 06/09/2024] [Accepted: 06/23/2024] [Indexed: 07/02/2024]
Abstract
Exposure to different environmental factors, social and socioeconomic factors promotes development of the early-life adversity (ELA) phenotype. The persistence of this phenotype across generations is an interesting phenomenon that remains unexplored. Of late many studies have focused on disease-associated outcomes of ELA following exposure during childhood but the persistence of epigenetic imprints transmitted by ELA exposed parents to their offspring remains poorly described. It is possible that both parents are able to transmit ELA-associated genetic imprints to their offspring via transgenerational inheritance mechanisms. Here, we highlight the role of the mother and father in the biological process of conception, from epigenetic reprogramming cycles to later environmental exposures. We explain some of the known determinants of ELA (pollution, socioeconomic challenges, infections, etc.) and their disease-associated outcomes. Finally, we highlight the role of epigenetics, mitochondria and ncRNAs as mechanisms mediating transgenerational inheritance. Whether these transgenerational inheritance mechanisms occur in the human context remains unclear but there is a large body of suggestive evidence in non-human models that points out to its existence.

Abstract
BACKGROUND Persons with HIV (PWHIV) on highly active antiretroviral treatments (HAART) may require specialized care based on health and demographic indicators. This study investigated the association of comorbidities, race, weight status, and gastrointestinal (GI) and cardiovascular (CV) symptoms among PWHIV. METHODS The Symptom Checklist, Co-Morbidity Questionnaire, and Sociodemographic Questionnaire were used to assess weight status and GI and CV symptoms among 283 PWHIV. Data were analyzed using latent class analysis on John's Macintosh Project 13 Platform. RESULTS Participants were majority Black (50%), 69% male, and 35% AIDS diagnosed. Ages were 25 to 66. Clusters included least symptomatic status, weight gain, and weight loss by Black and non-Black participants. The non-Black weight gain cluster reported a higher incidence of AIDS (70.6% vs 38.2%), nausea (70.6% vs 17.6%), diarrhea (70.6% vs 26.5%), and shortness of breath (58.8% vs 20.6%) compared to the Black weight gain cluster. The Black weight loss cluster reported a higher incidence of CV symptoms such as chest palpitations (42.2% vs 2.7%), chest pain (44.4% vs 8.1%), and shortness of breath (73.3% vs 35.1%). Moreover, the Black weight loss cluster reported a higher incidence of all GI symptoms with the most prominent being diarrhea (71.1% vs 48.6%) compared to the non-Black weight loss cluster. CONCLUSIONS The existing racial disparities in health-related quality of life for PWHIV may be improved through precision health and nutrition modifications. Continued research is needed investigating differential health outcomes among PWHIV on HAART. CLINICAL TRIAL REGISTRATION NUMBER NCT00222716. Registered 22 September 2005.

Abstract
OBJECTIVE Eating disorders (EDs) are mental illnesses impacting all aspects of an individual's life. Recent research has examined EDs and disordered-eating behaviors in the military, a population subject to body composition standards, fitness requirements, and extreme stress. The purpose of this narrative review was to investigate ED and disordered-eating prevalence and their risk factors in ROTC (reserve officers' training corps), active-duty, and veteran servicemembers. The secondary purpose was to provide policy recommendations to reduce the burden of these conditions in the military. METHODS PubMed and PsycINFO were reviewed for relevant articles. All studies including data on EDs or disordered eating in U.S. active-duty, ROTC, or veteran populations were considered. RESULTS Results revealed a high burden of EDs and disordered eating with bulimic- and binge-type behaviors being the most common. Servicemembers exposed to trauma, including military sexual assault, and those with comorbidities like PTSD showed a higher prevalence. Body composition and fitness testing were also associated with a higher risk. Qualitative studies suggest these conditions serve as coping mechanisms for aspects of military life. CONCLUSIONS The high prevalence of EDs and disordered eating in the military points toward the importance of identification, treatment, and prevention. Policy change is necessary to protect servicemembers.

Abstract
Aim This study aimed to explore the correlation between social determinants and overweight and obesity in children and youths with epilepsy. Methods The study data were derived from the National Survey of Children's Health (NSCH) 2016-2017 and 2018-2019, a cross-sectional sample of young people aged 10-17. Three groups participated by weight: 423 in body mass index (BMI) 5th-84th group (normal weight), 108 in BMI 85th-94th group (overweight), and 124 in BMI ≥ 95th group (obesity). Multivariate ordinal logistic regression analyses were conducted. The three subgroups were divided to explore the correlation between social determinants and overweight and obesity. Results A total of 655 children were included. After adjusting for sex, age, race, use of cigarets, cigars, or pipe tobacco inside, afterschool activity, and physical activity, children in poor physical condition reported by their parents [OR = 1.573 (95% CI, 1.164-2.125)] were associated with overweight/obesity. There were negative correlations between parents with higher education and overweight/obesity, especially in children and youths with previous or current epilepsy groups. Also, overweight/obesity was correlated with the 200%-400% family poverty level (FPL) [the adjusted odds ratio (OR) = 0.156 (95% CI, 0.028-0.876)] and above 400% FPL [the adjusted OR = 0.121 (95% CI, 0.023-0.641)] in children and youths with mild symptoms of epilepsy, and above 400% FPL [the adjusted OR = 0.103 (95% CI, 0.023-0.460)] in children with moderate to severe epilepsy. Conclusion Poor physical conditions were correlated with obesity in childhood epilepsy. Parents with higher education and FPLs were negatively correlated to childhood obesity. Therefore, this study was intended to advocate for a greater emphasis on BMI for children and youths with epilepsy in families with lower-educated and low-income groups.

Abstract
Previous researches have been conducted to study the associations of trace elements on Type 2 diabetes (T2D) risk. The present study focuses on the evaluation of potential associations between trace elements and Hemoglobin A1c (HbA1c) in patients with T2D, via the determination of their levels in human whole blood. 100 diabetes without complications, 75 prediabetes and 40 apparently healthy subjects were studied. The levels of eleven trace elements including lithium (Li), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), copper (Cu), zinc (Zn), selenium (Se), strontium (Sr) and molybdenum (Mo) were measured using inductively coupled plasma mass spectrometry (ICP-MS). The levels of fasting glucose, HbA1c, Hemoglobin, lipid, liver function, kidney function, thyroid function and demographic data were obtained from the Laboratory Information System. Nonparametric correlation (Spearman) was used to analyze the relationship between trace elements and HbA1c. The contents of V, Cr, Mn, Fe, Co, Cu, Zn and Mo in diabetes increased comparing with the healthy subject while Li decreased. But the levels of Li, V, Cr, Mn, Co, Se and Mo negatively correlated with HbA1c in the diabetes subjects (r value: - 0.2189, - 0.2421, - 0.3260, - 0.2744, - 0.2812, - 0.2456, - 0.2240; 95% confidence interval - 0.4032 to - 0.0176, - 0.4235 to - 0.0420, - 0.4955 to - 0.1326, - 0.4515 to - 0.0765, - 0.4573 to - 0.0838, - 0.4266 to - 0.0458, - 0.4076 to - 0.0229; p < 0.05, p < 0.05, p < 0.001, p < 0.01, p < 0.01, p < 0.05, p < 0.05). Accordingly, the contents of V, Cr, Mn and Se showed lower in HbA1c ≥ 7.0% group in contrast to HbA1c < 7.0% group. No correlation of HbA1c (or FBG) and trace elements was found in the healthy subjects. Trace element levels and metabolic abnormalities of blood glucose may be mutually affected. The extra supplement of trace elements needs to be cautious.

Abstract
Obesity is a worldwide epidemic and contributes to global morbidity and mortality mediated via the development of nonalcoholic fatty liver disease (NAFLD), type 2 diabetes (T2D), cardiovascular (CVD) and other diseases. It is a consequence of an elevated caloric intake, a sedentary lifestyle and a genetic as well as an epigenetic predisposition. This review summarizes changes in DNA methylation and microRNAs identified in blood cells and different tissues in obese human and rodent models. It includes information on epigenetic alterations which occur in response to fat-enriched diets, exercise and metabolic surgery and discusses the potential of interventions to reverse epigenetic modifications.

Abstract
DNA methylation could provide a link between environmental, genetic factors and weight control and can modify gene expression pattern. This study aimed to identify genes, which are differentially expressed and methylated depending on adiposity state by evaluating normal weight women and obese women before and after bariatric surgery (BS). We enrolled 24 normal weight (BMI: 22.5 ± 1.6 kg/m2) and 24 obese women (BMI: 43.3 ± 5.7 kg/m2) submitted to BS. Genome-wide methylation analysis was conducted using Infinium Human Methylation 450 BeadChip (threshold for significant CpG sites based on delta methylation level with a minimum value of 5%, a false discovery rate correction (FDR) of q < 0.05 was applied). Expression levels were measured using HumanHT-12v4 Expression BeadChip (cutoff of p ≤ 0.05 and fold change ≥2.0 was used to detect differentially expressed probes). The integrative analysis of both array data identified four genes (i.e. TPP2, PSMG6, ARL6IP1 and FAM49B) with higher methylation and lower expression level in pre-surgery women compared to normal weight women: and two genes (i.e. ZFP36L1 and USP32) that were differentially methylated after BS. These methylation changes were in promoter region and gene body. All genes are related to MAPK cascade, NIK/NF-kappaB signaling, cellular response to insulin stimulus, proteolysis and others. Integrating analysis of DNA methylation and gene expression evidenced that there is a set of genes relevant to obesity that changed after BS. A gene ontology analysis showed that these genes were enriched in biological functions related to adipogenesis, orexigenic, oxidative stress and insulin metabolism pathways. Also, our results suggest that although methylation plays a role in gene silencing, the majority of effects were not correlated.

Abstract
The objective of the present study was to evaluate the epigenetic changes occurring in early stages of breast cancer. The present study investigated the methylation profile of the ATM, p14ARF and p16INK4a promoters in total blood and plasma cell-free DNA (cfDNA) from women with impalpable breast lesions compared with in total blood of a control cohort of women without breast lesions. The samples were evaluated using the methylation-specific PCR method. The Fisher's exact test was used to evaluate statistical significance between the methylation and clinical variables. A total of 111 women were evaluated, including 56 women with impalpable breast cancer (39/56 also had paired plasma cfDNA) and 55 women in the control cohort (55 blood DNA). For blood DNA from women with malignant impalpable breast lesions, p16INK4a exhibited the greatest percentage of methylation (48%), followed by ATM (37.5%) and p14ARF (27%) promoters, regardless of age variation. For plasma cfDNA, the methylation rates for ATM, p14ARF and p16INK4a were 26, 26 and 10%, respectively. The methylation rates for the blood DNA of controls were the lowest for ATM (9%), p14ARF (7%) and p16INK4a (7%). The women with impalpable breast lesions (benign and malignant lesions) exhibited the highest methylation rate, regardless of age, compared with the paired plasma cfDNA and controls. This epigenetic change was statistically significant for the promoters of ATM (P=0.009) and p16INK4a (P=0.001) (impalpable breast lesions vs. control). The present study demonstrated that epigenetic changes occurring in the ATM and CDKN2A genes detectable in liquid biopsy were associated with the development of impalpable breast lesions.

Abstract
Incretins have risen to the forefront of therapies for obesity and related metabolic complications, primarily because of their efficacy and relatively few side effects. Importantly, their efficacy in altering energy balance and decreasing body weight is apparently through actions in the central nervous system (CNS); the latter may have implications beyond obesity per se, i.e. in other disease states associated with obesity including CNS-related disorders. Here, we first describe the role of the CNS in energy homeostasis and then the current state of knowledge in terms of incretin physiology, pathophysiology and efficacy in preclinical and clinical studies. In the future, more clinical studies are needed to fully map mechanistic pathways underlying incretin actions and outcomes in the human CNS. Additionally, future research will likely lead to the discovery of additional novel incretins and/or more efficacious medications with less side effects through the improvement of current compounds with properties that would allow them to have more favorable pharmacokinetic and pharmacodynamic profiles and/or by combining known and novel incretins into safe and more efficacious combination therapies leading ultimately to more tangible benefits for our patients.

Abstract
PURPOSE OF REVIEW This review summarizes our current understanding of factors associated with childhood obesity, including latest prevalence rates, effectiveness of intervention strategies, and risk for concomitant disease later in life. RECENT FINDINGS Obesity has reached global dimensions, and prevalence of childhood obesity has increased eightfold since 1975. Interventions for obesity prevention have mainly focused on behavioral settings to date, i.e., interventions that have focused on behavioral changes of the individuum such as increasing daily physical exercise or optimizing diet. However, effects have been very limited worldwide and could not stop the increase of obesity prevalence so fare. Thus, community-based/environment-oriented measures are urgently needed, such as promotion of healthy food choices by taxing unhealthy foods, mandatory standards for meals in kindergarten and schools, increase of daily physical activity at kindergartens, and schools as well as ban on unhealthy food advertisement for children. Restructuring obesity interventions towards community-based/environment-oriented measures to counteract an obesogenic environment is mandatory for sustainable success and to stop the obesity epidemy. There is need to move fast, as already moderate overweight before the start of puberty is associated with significantly increased risk for type 2 diabetes and cardiovascular disease in midlife.

Abstract
AIM The alteration in the gut microbial community has been regarded as one of the main factors related to obesity and metabolic disorders. To date, little is known about Moringa oleifera as a nutritional intervention to modulate the microbiota imbalance associated with obesity. Therefore we aim to explore the role of aqueous Moringa oleiferous leaf extract on Lactobacilli and Bifidobacteria in high-fat diet-induced obesity and to investigate whether any restoration in the number of caecal Lactobacilli and Bifidobacteria could modulate obesity-induced inflammation. METHODS Young Swiss albino mice were divided into three groups according to their diet. Two of them were fed on either high fat diet or high fat diet+aqueous extract of Moringa oleifera leaf, while the third group was fed on the control diet. Bacterial DNAs were isolated from the mice digesta samples for bacteria level estimation using Quantitative real-time polymerase chain reaction along with serum interleukin-6 and lipid profile. RESULTS Compared to the normal control mice, high-fat diet feeding mice showed significantly reduced intestinal levels of Bifidobacteria, and increased body weight, interleukin 6, and levels of Lactobacilli. Upon treatment with Moringa oleifera, body weight, interleukin 6, and both bacteria levels were significantly restored. CONCLUSIONS Our findings suggest that Moringa oliefera aqueous leaf extract may contribute towards the pathophysiological regulation of weight gain, inflammation associated with high-fat-induced-obesity through gut bacteria modulation.
