Mediterranean Diet: A Nutritional Suggestion for Long Covid Management Strategies – A Literature Review

Long COVID (LC) refers to continuing conditions following acute COVID-19 infection, lasting for weeks to months. It affects a wide range of people's lives, including physical, physiological, and social-economic aspects. Hence, leads to lowering quality of life and other future health challenges worldwide. Health problems following the acute phase of COVID-19 may persist or appear for days to months after the acute infection is resolved. The phenotype of long COVID-19 commonly manifests as a collection of symptoms such as muscle weakness, neuro-cognitive alteration, and respiratory disturbances. Mechanisms underpinning long COVID-19 are still not fully understood. It is hypothesized that inflammation plays a crucial role in LC development through several complex pathways. Recently, effective treatments for long COVID-19 have not been established. Its management depends on the patient's symptoms and needs. Nutritional modulation and physical rehabilitation are advised for long-COVID-19 improvement and increased quality of life. The Mediterranean diet (Med-diet) has been acknowledged for its impact on health through its antioxidant and anti-inflammatory effects. Bioactive compounds in Med-diet have been widely studied to reduce oxidative stress and inflammation in cells. Adherence to Med-diet food intake is linked to a lower incidence of obesity, cancer, cardiovascular disease, and metabolic disease. Therefore, the potential effect of Med-diet as a nutritional approach for long-COVID-19 treatment and prevention will be summarized.

Not Only Metabolic Complications of Childhood Obesity.

The increasing incidence of obesity in the pediatric population requires attention to its serious complications. It turns out that in addition to typical, well-known metabolic complications, obesity as a systemic disease carries the risk of equally serious, although less obvious, non-metabolic complications, such as cardiovascular diseases, polycystic ovary syndrome, chronic kidney disease, asthma, thyroid dysfunction, immunologic and dermatologic conditions, and mental health problems. They can affect almost all systems of the young body and also leave their mark in adulthood. In addition, obesity also contributes to the exacerbation of existing childhood diseases. As a result, children suffering from obesity may have a reduced quality of life, both physically and mentally, and their life expectancy may be shortened. It also turns out that, in the case of obese pregnant girls, the complications of obesity may also affect their unborn children. Therefore, it is extremely important to take all necessary actions to prevent the growing epidemic of obesity in the pediatric population, as well as to treat existing complications of obesity and detect them at an early stage. In summary, physicians treating a child with a systemic disease such as obesity must adopt a holistic approach to treatment.

The effect of insulin resistance in the association between obesity and hypertension incidence among Chinese middle-aged and older adults: data from China health and retirement longitudinal study (CHARLS).

Obesity and insulin resistance are well-known important risk factors for hypertension. This study aimed to investigate the mediating effect of the triglyceride-glucose index (TyG) in the association between Chinese visceral obesity index (CVAI) and hypertension among Chinese middle-aged and older adults. A total of 10,322 participants aged 45 years and older from CHARLS (2011-2018) were included. Baseline data were collected in 2011 and hypertension incidence data were gathered during follow-up in 2013, 2015 and 2018. Multivariate logistic regression models were constructed to investigate the association of CVAI and TyG with the incidence of hypertension. Additionally, mediation analyses were conducted to evaluate the mediating role of the TyG index in the relationship between CVAI and hypertension. Subgroup analysis was also performed. A total of 2,802 participants developed hypertension during the follow-up period. CVAI and TyG index were independently and significantly associated with hypertension incidence. Increasing quartiles of CVAI and TyG index were associated with high hypertension incidence in middle-aged and older adults. The TyG index was identified as a mediator in the relationship between CVAI and hypertension incidence, with a mediation effect (95% confidence interval) was 12.38% (6.75, 31.81%). Our study found that CVAI and TyG were independently associated with hypertension incidence. TyG played a partial mediating effect in the positive association between CVAI and hypertension incidence.

The relationship between Marriage and Body Mass Index in China：Evidence from the China Health and Nutrition Survey

This study investigates the impact of marriage on the body mass index (BMI) of individuals aged 18–45 in China. We used data from ten rounds of the China Health and Nutrition Survey spanning from 1989 to 2015, and applied Difference-in-Differences (DID) model to examine the impact of marriage on BMI. Our findings reveal that marriage has a significant positive effect on BMI, especially among males, with post-marriage elevation of male BMI continuing to increase over time. Moreover, marriage is associated with a 5.2% increase in the prevalence of overweight and a 2.5% rise in the incidence of obesity among males. While energy intake levels for Chinese women did not undergo significant changes after marriage, nor did their energy expenditure levels, men experienced a marked alteration in energy balance, characterized by an increase in caloric intake and a decrease in physical activity. Furthermore, our study confirms significant period differences in the effect of marriage on BMI, with post-marriage elevation of male BMI continuing to rise over time. In contrast, there was no clear trend for female BMI after marriage. Our research highlights the importance of promoting physical fitness and health management within families while fostering intimate relationships through marriage. Public health policies should consider the potential impact of marriage as an intervention window for addressing individuals' weight management needs. Distinct post-marriage body management plans should be designed for both genders.

Recent Progresses on Pathophysiology, Diagnosis, Therapeutic Modalities, and Management of Non-alcoholic Fatty Liver Disorder

Abstract: Non-alcoholic fatty liver disease (NAFLD) is currently the utmost common chronic liver disorder that happens through all age groups and is identified to occur in 14%-30% of the general population, demonstrating a critical and grossing clinical issue because of the growing incidence of obesity and overweight. From the histological aspect, it looks like alcoholic liver damage, but it happens in patients who avoid remarkable alcohol usage. NAFLD comprises a broad spectrum, ranging from benign hepatocellular steatosis to inflammatory nonalcoholic steatohepatitis (NASH), different levels of fibrosis, and cirrhosis. Patients with NASH are more susceptible to more rapid progression to cirrhosis and hepatocellular carcinoma. There is no single factor that drives proceeding from simple steatosis to NASH. However, a combination of multi parameters such as genetic background, gut microflora, intake of high fat/ fructose dietary contents or methionine/choline-deficient diet, and consequently accumulated hepatocellular lipids mainly including triglycerides and also other bio-analytes, such as free fatty acids, cholesterol, and phospholipids display a crucial role in disease promotion. NAFLD is related to overweight and insulin resistance (IR) and is regarded as the hepatic presentation of the metabolic syndrome, an amalgamation of medical statuses such as hyperlipidemia, hypertension, type 2 diabetes, and visceral obesity. Despite the increasing prevalence of this disease, which imposes a remarkable clinical burden, most affected patients remain undiagnosed in a timely manner, largely related to the asymptomatic entity of NAFLD patients and the unavailability of accurate and efficient noninvasive diagnostic tests. However, liver biopsy is considered a gold standard for NAFLD diagnosis, but due to being expensive and invasiveness is inappropriate for periodic disease screening. Some noninvasive monitoring approaches have been established recently for NAFLD assessment. In addition to the problem of correct disease course prediction, no effective therapeutic modalities are approved for disease treatment. Imaging techniques can commonly validate the screening and discrimination of NAFLD; nevertheless, staging the disease needs a liver biopsy. The present therapeutic approaches depend on weight loss, sports activities, and dietary modifications, although different insulin-sensitizing drugs, antioxidants, and therapeutic agents seem hopeful. This review aims to focus on the current knowledge concerning epidemiology, pathogenesis, and different biochemical experiments and imaging modalities applied to diagnose the different grades of NAFLD and its management, as well as new data about pharmacological therapies for this disorder.

Impact of preconception and antenatal supplementation with myo-inositol, probiotics, and micronutrients on offspring BMI and weight gain over the first 2 years

BackgroundNutritional intervention preconception and throughout pregnancy has been proposed as an approach to promoting healthy postnatal weight gain in the offspring but few randomised trials have examined this.MethodsMeasurements of weight and length were obtained at multiple time points from birth to 2 years among 576 offspring of women randomised to receive preconception and antenatally either a supplement containing myo-inositol, probiotics, and additional micronutrients (intervention) or a standard micronutrient supplement (control). We examined the influence on age- and sex-standardised BMI at 2 years (WHO standards, adjusting for study site, sex, maternal parity, smoking and pre-pregnancy BMI, and gestational age), together with the change in weight, length, BMI from birth, and weight gain trajectories using latent class growth analysis.ResultsAt 2 years, there was a trend towards lower mean BMI among intervention offspring (adjusted mean difference [aMD] − 0.14 SD [95% CI 0.30, 0.02], p = 0.09), and fewer had a BMI > 95th percentile (i.e. > 1.65 SD, 9.2% vs 18.0%, adjusted risk ratio [aRR] 0.51 [95% CI 0.31, 0.82], p = 0.006). Longitudinal data revealed that intervention offspring had a 24% reduced risk of experiencing rapid weight gain > 0.67 SD in the first year of life (21.9% vs 31.1%, aRR 0.76 [95% CI 0.58, 1.00], p = 0.047). The risk was likewise decreased for sustained weight gain > 1.34 SD in the first 2 years of life (7.7% vs 17.1%, aRR 0.55 [95% CI 0.34, 0.88], p = 0.014). From five weight gain trajectories identified, there were more intervention offspring in the “normal” weight gain trajectory characterised by stable weight SDS around 0 SD from birth to 2 years (38.8% vs 30.1%, RR 1.29 [95% CI 1.03, 1.62], p = 0.029).ConclusionsSupplementation with myo-inositol, probiotics, and additional micronutrients preconception and in pregnancy reduced the incidence of rapid weight gain and obesity at 2 years among offspring. Previous reports suggest these effects will likely translate to health benefits, but longer-term follow-up is needed to evaluate this.Trial registrationClinicalTrials.gov, NCT02509988 (Universal Trial Number U1111-1171–8056).

THE IMPACT OF OBESITY ON THE PREVALENCE AND SEVERITY OF PERIANAL COMPLICATIONS OF CROHN'S DISEASE

Abstract INTRODUCTION The incidence of obesity in patients with inflammatory bowel disease (IBD) is increasing and there is limited data on the effects of obesity on disease phenotype. Several studies have investigated the association of obesity with perianal fistulizing disease with conflicting results. In this study, we aim to examine the relationship between obesity and the prevalence and severity of perianal complications in patients with Crohn’s disease (CD). METHODS We conducted a cross-sectional study of CD patients treated at a tertiary care center from 2012 to 2022. Collected data included sex, race, smoking history, family history, maximum body mass index (BMI), and Montreal classification (Table 1). Obesity was defined as maximum BMI ≥30kg/m2 and further subdivided into 5 BMI categories (Table 2). The prevalence of perianal disease was defined by a history of perianal fistula. The severity of perianal disease was measured by four variables including history of perianal fistula surgery, number of perianal surgeries, history of fecal diversion, and median time to first anal surgery. Perianal fistula surgeries included abscess incision and drainage, seton placement, fistulectomy, and/or fistulotomy. Pearson’s chi-squared test was used to compare 2 categorical variables (non-obese vs obese). Exact Cochran-Armitage trend test was used to compare 5 BMI categorical variables. A 95% confidence interval was used with an alpha of 0.5. Values of p <0.05 was considered statistically significant. Data analysis was performed using Excel. RESULTS A total of 704 patients with CD were treated. In all, 68.9% were non-obese and 31.1% were obese. Furthermore, 2.8% were underweight, 36.5% normal weight, 29.5% overweight, 17.9% obese, and 13.2% severely obese. Non-obese patients were more likely to have a family history of IBD (p=0.043). Obese patients were more likely to have extraintestinal manifestations (p=0.004) and/or be former smokers (p=0.004). There was no significant association between obesity and prevalence of perianal fistula (p=0.719), history of perianal surgery (p=0.146), history of one or more perianal surgeries (p=0.220), history of fecal diversion (p=0.705) or median time to first perianal surgery (p=0.192) (Table 1). Increasing BMI category was not associated with the prevalence of perianal fistula (p=0.944), perianal surgery (p=0.583), more than one perianal surgery (p=0.114), fecal diversion (p=0.542) or median time to first perianal surgery (p=0.486) (Table 2). DISCUSSION In conclusion, there was no significant correlation between obesity and prevalence of perianal disease. Additionally, there was no significant correlation between obesity and severity of perianal disease. The overall impact of obesity on CD complications is still unknown and warrants further investigation.

Body Weight Perception and its Relationship with Anthropometric Indices of Undergraduate Students in Port Harcourt, Nigeria

Purpose: The aim of the present study was to evaluate body weight perception and its relationship with anthropometric indices and blood glucose of undergraduate students in Port Harcourt. Methodology: The study involved a total of 600 undergraduate students aged 18-35 years (including 249 males and 351 females). Body weight perception was assessed using a structured questionnaire. The anthropometric indices (weight, height, waist, hip and shoulder circumference and foot length) of each subject were measured using standard methods while the ratios were calculated. Findings: The average BMI of undergraduates was 23.66�±0.13kg/m2. There was no significant gender difference in BMI, hip circumference and foot length. Waist circumference and waist-to-hip ratio were significantly higher in males while waist-to-height ratio was significantly higher in females. There was significant correlation between BMI and hip circumference, shoulder circumference and waist circumference but no significant correlation exists between BMI and foot length. The incidence of obesity amongst undergraduates in Port Harcourt was as low as 3.3% using the measured BMI even when only 1.5% admitted being obese. The actual BMI classified overweight was 25.7% as against perceived overweight of 19.8%. Only 56.3% perceived themselves to be within the normal weight whereas up to 67.5% were actually normal weight. The incidence of underweight was 3.5% but as many as 22.3% of undergraduates perceived they were underweight. Unique Contribution of Theory, Practice and Policy: Waist-to-height ratio therefore was more useful in assessing abdominal size in females while waist-to-hip ratio was more useful in assessing abdominal size in young adult males. Amongst the anthropometric indices, foot length was a poor tool in assessing body weight.

Impacts of combining Limosilactobacillus reuteri KUB‐AC5 and Limosilactobacillus fermentum KUB‐D18 on overweight gut microbiota using a simulated human colon model

SummaryHigh‐fat diets lead to fat accumulation and contribute to the incidence of obesity, which has now become a global public health problem. High‐fat diets directly impact the microbial composition of the gastrointestinal tract, causing an imbalance in the gut microbiota. This study investigated the effect of probiotics Limosilactobacillus reuteri KUB‐AC5 and Limosilactobacillus fermentum KUB‐D18 in reducing the negative effects associated with the consumption of a high‐fat diet. Results of metagenomics analysis demonstrated that the probiotics regulated the abundance of Enterobacteriaceae, a recognised biomarker of gut dysbiosis. The other observation was the induction of beneficial microbes in the family Bifidobacteriaceae. Supplementation with probiotics in a high‐fat diet significantly reduced phenol, the toxic compound produced by gut microbes (P = 0.032), and promoted the production of beneficial metabolites, including trans‐cinnamic acid and L‐(−)‐3‐phenyllactic acid (P = 0.002 and 0.007, respectively). Results suggested the potential benefits of L. reuteri KUB‐AC5 and L. fermentum KUB‐D18 to alleviate the negative health risks of obesity associated with the consumption of a high‐fat diet. These probiotics offer potential benefits as future health management alternatives.

Interactions of Body Weight Loss with Lipophilic Toxin Storage: Commentary

A high incidence of obesity and surplus body fat has been observed in wealthy countries for many decades. It is generally recognized that these excesses contribute to serious disease states, including type 2 diabetes and cardiovascular diseases. On the other hand, the adipose tissue stores relatively safely many environmental lipophilic toxins. However, rapid weight loss mobilizes these toxins to the blood to be exposed to vital organs, such as the brain, lungs, and others. With the introduction of potent diabetic drugs causing rapid weight reduction, the question of mobilization of lipophilic toxins to the blood should be considered. In this commentary, we raised this mobilization of adipose tissue toxins to the readers. Also, we discussed how these toxins may be eliminated from the body through the use of nondigestible fat, such as olestra or lipase inhibitors, such as Xenical.

Abstract B048: Targeting PPARG to block obesity-associated pancreatic cancer progression

Abstract Pancreatic ductal adenocarcinoma (PDA) is the 3rd leading cause of cancer-related death in the United States and one of the few cancers for which incidence is increasing. This trend in increased incidence has been attributed in part to obesity. Obesity is associated with increased risk of pancreatic cancer and advanced disease stage in patients, concordant with rodent studies showing that obesity accelerates tumorigenesis and metastasis. Although studies have largely focused on the role of inflammation in obesity-associated pancreatic cancer, the cancer cell-autonomous mechanisms by which lipid availability in obesity impacts tumorigenesis remain quite poorly understood. Given the abundant evidence for dysregulated lipid metabolism in tumors, I hypothesized that cancer cells are primed to exploit exogenous lipids in obesity, accelerating disease progression. By mapping lipid-protein interactions in tumor and metastasis-enriched RNA-seq networks, I identified the nuclear hormone receptor PPARG as a potential mediator of obesity-associated lipid signaling in pancreatic cancer. PPARG is an attractive prospective mediator of obesity-associated PDA progression because it is a metabolic regulator activated by a broad set of lipid ligands, suggesting a dual role in lipid sensing and metabolic control. PPARG is also positioned at an interesting junction in PDA etiology; PPARG agonists are used to treat diabetes (a PDA risk factor) and have previously been studied for anti-cancer effects. However, PPARG agonists have seen little clinical success in and recent work has suggested that their use may even increase bladder cancer risk. PPARG is overexpressed in pancreatic tumors where it is associated with poor prognosis, further casting doubt on its anti-tumorigenic function. In my own studies, I found that PPARG agonists had no effect on tumor viability, while the PPARG antagonist T0070907 reduced organoid viability in vitro. Modeling the convergent effects of PPARG and obesity, I supplemented organoids with a mixture of lipids in the presence of PPARG antagonist and found that lipids boosted the viability of both tumor and metastatic organoids dependent on PPARG activity in vitro. These results suggest that PPARG can mediate the pro-tumorigenic function of exogenous lipids. As the incidence of both obesity and pancreatic cancer continue to rise, defining the role of PPARG in PDA could have significant implications for the development of new strategies to treat or prevent obesity-associated cancer.

Metabolic effects of milk fatty acids: A literature review.

Milk and dairy products are known to have a significant role in human development and tissue maintenance due to their high nutritional value. With the higher incidence of obesity and metabolic diseases, nutrition and public health authorities have recommended the intake of fat-free or low-fat dairy due to the saturated fatty acid content of whole-fat products and their effect on serum cholesterol levels. However, recent studies have questioned the association between milk fat consumption and cardiometabolic risk. This literature review aims to compile the scientific evidence of the metabolic effects of milk fatty acids in clinical and basic research studies, as well as their relationship with metabolic disorders and gut microbiota composition. Research shows that various milk fatty acids exert effects on metabolic alterations (obesity, type 2 diabetes and cardiovascular diseases) by modifying glucose homeostasis, inflammation and lipid profile-related factors. Additionally, recent studies have associated the consumption of milk fatty acids with the production of metabolites and the promotion of healthy gut microbiota. From mainly observational studies, evidence suggests that milk and dairy fatty acids are not directly linked to cardiometabolic risk, but further controlled research is necessary to clarify such findings and to assess whether dietary recommendations to choose low-fat dairy foods are necessary for the population for the prevention of obesity and cardiometabolic disease.

Review of impacts of using body mass index as a screening tool in school children: A scoping review.

Body mass index (BMI) is used to screen for under- or overweight. However, it is unknown whether BMI-screening in school children reduces the incidence of overweight and obesity. We aimed to summarise the knowledge on positive and negative consequences on BMI and weight-related perceptions and behaviours of BMI-screening followed by an intervention to prevent and/or address obesity. We performed a systematic literature search, April 2023, using the PubMed, ScienceDirect and Google Scholar databases. We included randomised controlled trials and observational studies, including children aged 6 to 18 years and examining BMI-screening in a school setting. The primary outcome measures were BMI and weight status. Secondary outcome measures were weight-related perceptions and behaviours. Three studies met the inclusion criteria; two randomised controlled trials and one observational study. All studies used BMI-screening followed by sending report cards to the parents. None of the studies found a change in BMI z-scores in school children. Screening could cause transitory body-dissatisfaction and increase peer weight talk, yet potentially reduce problematic weight behaviours like skipping meals or excessive dieting. Reporting BMI to parents may influence their perception of their children's weight status, but does not change behaviour. The sparse evidence available suggested that BMI screening followed by sending report cards to parents does not change BMI z-scores among children in primary, middle and high school. Studies using appropriate evidence-based weight management interventions as a follow-up are lacking. Such studies may improve future prevention, detection and treatment of weight-related issues.

Interaction between adolescent sleep rhythms and gender in an obese population.

The obesity rate of adolescents is gradually increasing, which seriously affects their mental health, and sleep plays an important role in adolescent obesity. To investigate the relationship between sleep rhythm and obesity among adolescents and further explores the interactive effect of sleep rhythm and gender on adolescent obesity, providing a theoretical basis for developing interventions for adolescent obesity. Research data source Tianjin Mental Health Promotion Program for Students. From April to June 2022, this study selected 14201 students from 13 middle schools in a certain district of Tianjin as the research subject using the convenient cluster sampling method. Among these students, 13374 accepted and completed the survey, with an effective rate of 94.2%.The demographic data and basic information of adolescents, such as height and weight, were collected through a general situation questionnaire. The sleep rhythm of adolescents was evaluated using the reduced version of the morningness-eveningness questionnaire. A total of 13374 participants (6629 females, accounting for 49.56%; the average age is 15.21 ± 1.433 years) were analyzed. Among them, the survey showed that 2942 adolescent were obesity, accounting for 22% and 2104 adolescent were overweight, accounting for 15.7%. Among them, 1692 male adolescents are obese, with an obesity rate of 25.1%, higher than 18.9% of female adolescents. There is a statistically significant difference between the three groups (χ2 = 231.522, P < 0.000). The obesity group has the smallest age (14.94 ± 1.442 years), and there is a statistical difference in age among the three groups (F = 69.996, P < 0.000).Obesity rates are higher among individuals who are not-only-child, have residential experience within six months, have family economic poverty, and have evening-type sleep (P < 0.05). Logistic regression analysis shows a correlation between sleep rhythm and adolescent obesity. Evening-type sleep rhythm can increase the risk of obesity in male adolescents [1.250 (1.067-1.468)], but the effect on female obesity is not remarkable. Further logistic regression analysis in the overall population demonstrates that the interaction between evening-type sleep rhythm and the male gender poses a risk of adolescent obesity [1.122 (1.043-1.208)]. Among adolescents, the incidence of obesity in males is higher than in females. Evening-type sleep rhythm plays an important role in male obesity but has no significant effect on female obesity. Progressive analysis suggests an interactive effect of sleep rhythm and gender on adolescent obesity, and the combination of evening-type sleep and the male gender promotes the development of adolescent obesity. In formulating precautions against adolescent obesity, obesity in male adolescents with evening-type sleep should be a critical concern.

The Effects of High Fat Diet on the Incidence of Obesity and Monocyte Chemoattractant Protein-1 Levels on Histological Changes in Prostate Wistar Rats.

Benign prostatic hyperplasia (BPH) is a histopathological diagnosis characterized by the increase in stromal cells and epithelial cells of the prostate gland in the transitional zone surrounding the urethra. Obesity is the risk factor of BPH. The most frequent cause of obesity is a high-fat diet (HFD). Obesity and HFD lead to pro-inflammatory conditions. One of the pathomechanisms for the occurrence of BPH is a low-degree inflammatory factor, one of which is the level of monocyte chemoattractant protein-1/MCP-1. This study aims to determine the influence of HFD on the incidence of obesity and inflammatory factors (monocyte chemoattractant protein-1/MCP-1 levels) on the histopathological picture of the prostate. Experimental research was performed on male Wistar rats with each of the 6 rats given normal fat (ND) and HFD intake and terminated at 8 weeks and 6 rats given each ND and HFD were terminated at 16 weeks. The determination of obesity was determined based on Lee's criteria which were categorized as obese if the Lee index >0.3 and non-obese if ≤0.3. Examination of circulating MCP-1 was carried out by the ELISA method and determination of prostatic hyperplasia was done by calculating the percentage of prostate glands that had a large per-field cystic dilatation on light microscopy examination. All data are analyzed statistically with the Fisher Exact Test and Spearman Correlation Test. Of the 12 rats that were given ND, none of them became obese according to Lee's criteria, on the other hand, of the 12 rats that were given HFD 8 became obese (66.7%, p = 0.001). Serum MCP-1 levels and the percentage of prostate glands that had cystic dilatation were significantly higher in mice receiving HFD than ND; both at week-8 (MCP-1; 18.87 vs 15.66) and (prostate gland experiencing cystic dilatation; 63.46% vs 47.24%) and week-16 (MCP-1; 21.27 vs 21.27) and (prostate gland experiencing cystic dilatation; 67.79% vs 56.39%). Spearman correlation analysis showed that only circulating MCP-1 levels were significantly correlated (p < 0.05) to the percentage of the prostate gland that had cystic dilatation; especially in week 16 (r = 0.713 and p < 0.001). At 8 weeks, it was not statistically significant (r = 0.406 and p = 0.095). High fat intake has been shown to increase the risk of obesity, but obesity does not increase inflammatory status and the incidence of prostate glands with cystic dilatation. On the other hand, high-fat intake increases inflammatory status which in turn causes prostate glands to develop cystic dilatation.

Spatial analysis of the prevalence of abdominal obesity in middle-aged and older adult people in China: exploring the relationship with meteorological factors based on gender differences.

In recent years, the incidence of abdominal obesity among the middle-aged and older adult population in China has significantly increased. However, the gender disparities in the spatial distribution of abdominal obesity incidence and its relationship with meteorological factors among this demographic in China remain unclear. This gap in knowledge highlights the need for further research to understand these dynamics and inform targeted public health strategies. This study utilized data from the 2015 China Health and Retirement Longitudinal Study (CHARLS) to analyze the incidence of abdominal obesity among the middle-aged and older adult population in China. Additionally, meteorological data were collected from the National Meteorological Information Center. Using Moran's I index and Getis-Ord Gi* statistical methods, the spatial distribution characteristics of abdominal obesity incidence were examined. The influence of various meteorological factors on the incidence of abdominal obesity in middle-aged and older adult males and females was investigated using the q statistic from the Geodetector method. Furthermore, Multi-Scale Geographically Weighted Regression (MGWR) analysis was employed to explore the impact of meteorological factors on the spatial heterogeneity of abdominal obesity incidence from a gender perspective. The spatial distribution of abdominal obesity among middle-aged and older adult individuals in China exhibits a decreasing trend from northwest to southeast, with notable spatial autocorrelation. Hotspots are concentrated in North and Northeast China, while cold spots are observed in Southwest China. Gender differences have minimal impact on spatial clustering characteristics. Meteorological factors, including temperature, sunlight, precipitation, wind speed, humidity, and atmospheric pressure, influence incidence rates. Notably, temperature and sunlight exert a greater impact on females, while wind speed has a reduced effect. Interactions among various meteorological factors generally demonstrate bivariate enhancement without significant gender disparities. However, gender disparities are evident in the influence of specific meteorological variables such as annual maximum, average, and minimum temperatures, as well as sunlight duration and precipitation, on the spatial heterogeneity of abdominal obesity incidence. Meteorological factors show a significant association with abdominal obesity prevalence in middle-aged and older adults, with temperature factors playing a prominent role. However, this relationship is influenced by gender differences and spatial heterogeneity. These findings suggest that effective public health policies should be not only gender-sensitive but also locally adapted.

The role of TRPV ion channels in adipocyte differentiation: What is the evidence?

AbstractObesity is a complex disorder, and the incidence of obesity continues to rise at an alarming rate worldwide. In particular, the growing incidence of overweight and obesity in children is a major health concern. However, the underlying mechanisms of obesity remain unclear and the efficacy of several approaches for weight loss is limited. As an important calcium‐permeable temperature‐sensitive cation channel, transient receptor potential vanilloid (TRPV) ion channels directly participate in thermo‐, mechano‐, and chemosensory responses. Modulation of TRPV ion channel activity can alter the physiological function of the ion channel, leading to neurodegenerative diseases, chronic pain, cancer, and skin disorders. In recent years, increasing studies have demonstrated that TRPV ion channels are abundantly expressed in metabolic organs, including the liver, adipose tissue, skeletal muscle, pancreas, and central nervous system, which has been implicated in various metabolic diseases, including obesity and diabetes mellitus. In addition, as an important process for the pathophysiology of adipocyte metabolism, adipocyte differentiation plays a critical role in obesity. In this review, we focus on the role of TRPV ion channels in adipocyte differentiation to broaden the ideas for prevention and control strategies for obesity.

Associations of school physical activity environment with comorbid obesity and myopia in children and adolescents: Findings from a Chinese national follow-up study.

Overweight and obesity (OWOB) and myopia have become two of the most important issues affecting the health of children and adolescents worldwide. Despite the recognition that the school physical activity (PA) environment is a critical factor for preventing and controlling overweight, obesity (OWOB), and myopia in children and adolescents, research on OWOB and myopia as a comorbidity remains unexplored, with evidence for effective strategies still being inconclusive. Hence, this study aimed to assess the prevalence and progression of comorbid OWOB/myopia and each condition alone, and to explore the association with school PA environment. A total of 9814 children and adolescents aged 6-18 years were included from the Chinese National Survey on Students' Constitution and Health follow-up survey conducted from November 2019 to November 2020 in China. Anthropometric measurements, unaided distance vision acuity and non-cycloplegic refraction data were collected to assess OWOB and myopia, while eight indicators from questionnaires for children and adolescents aged 9-18 years were investigated to assess school PA environment. We calculated the one-year incidence and progression rates of comorbid OWOB/myopia, OWOB alone, and myopia alone. Mixed effect logistic regression was evaluated the association between school PA environment and incidence and progression of comorbid OWOB/myopia, OWOB, and myopia. The prevalence of comorbid OWOB/myopia increased from 11.1% in 2019 to 17.9% in 2020, and the incidence of comorbid OWOB/myopia was 10.9%. Children and adolescents experiencing an unfavorable school PA environment had a higher risk of the incidence of comorbid OWOB/myopia compared to a favorable school environment (OR = 1.85, 95% CI: 1.42-2.42). Similar findings were seen in the incidence of obesity (OR = 1.86, 95% CI: 1.26-2.75). Children and adolescents in an unfavorable school PA environment had a higher risk of myopia progression (OR = 1.29, 95% CI: 1.01-1.65). Obesity and myopia and their comorbidity have been serious among children and adolescents in China. A favorable school PA environment might mitigate the risk of comorbid OWOB/myopia, OWOB, and myopia progression.

Hop (Humulus lupulus L.) extract reverts glycaemic imbalance and cognitive impairment in an animal model of obesity.

The rates of overweight and obesity around the world have increased in past years. The body's adipose tissue stimulates the antioxidant and oxidation imbalance capacity at the cellular level. This scenario favors an inflammatory low-grade systemic condition starting with insulin resistance, which in turn may involve diabetes mellitus type 2 and cognitive decline afterward. Neurological diseases have been correlated to senile age diseases over time. This scenario calls for a change in the incidence of obesity in the younger generation. An unhealthy dietary consumption together with sedentary habits might lead to poor gut absorption of nutrients. Several plants and foods have bioactive compounds that can reduce or inhibit radical scavengers, reactive oxygen species, and metal ion complexes that threaten the cerebral defense system. The bitter acids from hops (Humulus lupulus L.) have been demonstrated to have promising effects on lipid and carbohydrate metabolism improvement, reducing inflammatory responses through alpha acids, beta acids, and analogs action. Therefore, the current study aimed to investigate the bioactivity of hop bitter acids in obese and lean mice. For that, a dry hop extract (DHE) was obtained by applying carbon dioxide as the fluid of supercritical extraction. Afterward, seventy-eight male mice of the C57BL/6J strain were weighed and randomly distributed into six groups of 13 animals each according to the diet offered: (NO) normolipidic diet, (NO1) normolipidic diet containing 0.35% alpha acids, (NO2) normolipidic diet containing 3.5% alpha acids, (HP) hyperlipidic diet, (HP1) hyperlipidic diet containing 0.35% alpha acids, and (HP2) hyperlipidic diet containing 3.5% alpha acids. After applying the glycemic tolerance and insulin tolerance tests, a better stabilization of glycemia levels and weight gain among those animals fed with DHE (NO2 and HP2) were observed in comparison to the obese control group (HP) (p < 0.05). There was also an amelioration of antioxidant capacity observed by checking the enzymatic profile by SOD and an apparent mitigation of brain degeneration by checking GSK3β and p-IRS1 proteins expression (p < 0.05). The y-maze cognitive test applied to highlight possible obesity-harmful animal brains did not indicate a statistical difference between the groups. Although the weekly dietary intake between the obese HP2 group (33.32 ± 4.11, p < 0.05) and control HP (42.3 ± 5.88, p < 0.05) was different. The bioactive compounds present in DHE have demonstrated relevant effects on glycemic control, insulin signaling, and the consequent modulatory action of the obesity-related markers with the brain's inflammatory progression.

Прогнозирование гестационного сахарного диабета на ранних сроках беременности у женщин с ожирением

Aim. Analysis of the possibilities of predicting gestational diabetes mellitus in early pregnancy in obese women. Key points. The incidence of obesity and gestational diabetes mellitus among the female population in the world is steadily increasing. Obesity is an independent risk factor for gestational diabetes. Diabetes mellitus, which occurred during pregnancy, is associated with a number of complications for both the mother and the fetus. The presented literature review summarizes modern ideas about the prognosis of gestational diabetes mellitus in early pregnancy in obese women. Data on the effectiveness of various prognostic factors of gestational diabetes are presented. Conclusion. To date, both clinical and laboratory predictors of gestational diabetes are known, but there are no regulated criteria for its diagnosis in the early stages of pregnancy. There is a need to conduct large-scale studies in order to select the most significant predictors of this disease in obese women and introduce them into the practical activities of an obstetrician-gynecologist. Keywords: prediction, gestational diabetes mellitus, obesity.
