Caloric Intake Research Articles

Is there any association between type of dietary fat and quality of life in hemodialysis patients? A cross-sectional study.

Hemodialysis (HD) patients have a low quality of life (QOL), and dietary intakes may impact both somatic and psychosocial aspects of QOL. Nevertheless, the relationship between QOL and different dietary fats has not yet been evaluated. The purpose of this study was to assess the association between QOL and the types/quantities of dietary fats intake in HD patients. In this multi-center cross-sectional study, 251 adult patients under dialysis for at least 3 months were included. Participants' dietary intakes were collected using a validated 168-item semi-quantitative FFQ during the past year. Moreover, to assess QOL, Kidney Disease Quality of Life Short Form (KDQOL-SF 1/3) was used. The linear regression between QOL and different types of dietary fats was conducted. p < 0.05 was statistically significant. Overall, 66 women and 185 men participated in our study. Regression analysis adjusted for total calorie intake showed that there was a negative association between QOL and total fat (95% CI: -0.187, -0.043), SFA (95% CI: -0.688, -0.143), MUFA (95% CI: -0.389, -0.065) and PUFA (95% CI: -0.401, -0.056) when types of dietary fats were individually included to the regression analysis. When all types of dietary fats were simultaneously entered into the analysis, the association between QOL and MUFA (95% CI: -0.243, 1.031) and PUFA (95% CI: -1.159, 0.084) were attenuated. The regression coefficient for SFA remained significant (95% CI: -0.968, -0.138). Also, there was a marginally significant association between SFA and the risk of low QOL was observed when all types of dietary fats were simultaneously entered into the analysis (OR = 1.051, 95% CI: 0.998-1.104). Our investigation found a negative association between SFA consumption and QOL among different types of dietary fats. Furthermore, SFA mediated the relationship between QOL, MUFA, PUFA, and total fat. So, modification of dietary fat intake could enhance QOL in HD patients.

Assessing Clinical Variables Associated With Femoral Muscle Decay as Measured by Point‐of‐Care Ultrasound in Critically Ill Children

ObjectivesSkeletal muscle wasting is a common occurrence in critical illness, often resulting in intensive care unit (ICU)‐acquired weakness. This study aims to identify clinical factors associated with muscle decay in mechanically ventilated critically ill children. Utilizing point‐of‐care ultrasound, a noninvasive and cost‐effective tool, we assess muscle decay through ultrasound of the quadriceps femoris.MethodsA prospective observational study was conducted in a single‐center quaternary‐care pediatric intensive care unit at a children's hospital. A convenience sample of 103 sedated and mechanically ventilated patients were enrolled in this study. Ultrasound measurements of quadriceps femoris muscle thickness were taken, and daily muscle decay rates were calculated. Demographic, clinical, and outcome data were analyzed for correlations with muscle decay.ResultsAmong the enrolled patients, 67 had repeat measurements. Muscle thickness change aligned with prior studies, with a mean daily change of −1.9% [IQR −0.8, −5.0]. Adequate cumulative caloric intake (&gt;60% of goal) correlated with less muscle decay compared with inadequate intake (−1.8 vs −2.4%, P &lt; .001). Average daily muscle change correlated with both ICU and hospital length of stay (LOS) (r = .328, P = .007 and r = .393, P = .001). No significant correlations emerged between muscle change and mortality, disease severity, fluid balance, early mobilization, steroid exposure, or sedative and paralytic use.ConclusionThis study demonstrates early and frequent muscle decay in critically ill children, as detected by point‐of‐care ultrasound. Average daily muscle decay was associated with longer ICU and hospital LOS. Adequate cumulative caloric intake is linked to reduced muscle decay. These findings contribute to understanding muscle wasting in critically ill pediatric patients.

Daily Orange Consumption Reduces Hepatic Steatosis Prevalence in Patients with Metabolic Dysfunction-Associated Steatotic Liver Disease: Exploratory Outcomes of a Randomized Clinical Trial.

Background: Consumption of flavonoid-rich orange juice has been shown to reduce adiposity and liver steatosis in murine models of diet-induced obesity. However, little is known about the effects of whole orange intake, independent of body weight changes, on liver function and steatosis in individuals with metabolic dysfunction-associated steatotic liver disease (MASLD). The goal is to understand the direct impact of orange consumption on metabolic health. Methods: Sixty-two men and women aged 30-65 with MASLD (Controlled Attenuation Parameter, (CAP) > 275 dB/m) were randomly assigned to consume either 400 g of whole oranges or non-citrus fruits daily for 4 weeks. Baseline evaluations included medical assessments, blood tests, and body composition. Liver health was assessed using transient elastography (FibroScan®) for steatosis and fibrosis, conducted by blinded personnel. This clinical trial was registered at ClinicalTrials.gov (NCT05558592). Results: After 4 weeks of orange supplementation, liver steatosis decreased in the treatment group, with 70.9% showing steatosis compared to 100% in controls (p < 0.004), indicating a 30% reduction in liver disease prevalence. There were no significant changes in fibrosis or plasma liver enzymes, though plasma gamma glutaril transferase (GGT) levels decreased significantly. Body weight, waist circumference, body composition, lipid profile, fasting glucose, insulin, and C-reactive protein levels remained unchanged. Dietary analysis revealed no change in caloric intake, but vitamins C, A, thiamine, and riboflavin increased in the orange group. Conclusions: Our findings suggest that phytochemical-rich foods, especially whole fruits like oranges, may enhance liver function as an adjunct treatment for MASLD. The notable reduction in liver steatosis prevalence occurred independently of body weight changes. Further studies are needed to investigate the long-term effects of orange supplementation on steatosis and fibrosis progression and to identify the specific bioactive compounds and mechanisms involved.

Effects of Dietary Changes on Feline Obesity in Cats in the United States

Purpose: To aim of the study was to analyze the effects of dietary changes on feline obesity in cats in the United States. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: Recent studies indicate that dietary changes play a crucial role in addressing feline obesity in the United States. Research shows that transitioning to high-protein, low-carbohydrate diets can significantly reduce weight gain and promote healthier body conditions in cats. Additionally, the incorporation of portion control and feeding schedules, alongside the use of specialized weight management foods, has been linked to effective weight loss in overweight felines. The findings also highlight the importance of increasing fiber content in cat diets, which aids in satiety and reduces overall calorie intake. Furthermore, educating pet owners about the impact of treats and the need for regular veterinary consultations can enhance dietary compliance and improve feline health outcomes. Unique Contribution to Theory, Practice and Policy: Energy balance theory, obesity hypoventilation syndrome (OHS) theory &amp; behavioral theory of eating may be used to anchor future studies on the effects of dietary changes on feline obesity in cats in the United States. Practically, to address feline obesity, pet owners and veterinarians should adopt several evidence-based dietary strategies. From a policy perspective, several key actions are recommended to address feline obesity on a broader scale.

Synergy between time-restricted feeding and time-restricted running is necessary to shift the muscle clock in male wistar rats

Circadian disruption is an important factor driving the current-day high prevalence of obesity and type-2 diabetes. While the impact of incorrect timing of caloric intake on circadian disruption is widely acknowlegded, the contribution of incorrect timing of physical activity remains relatively understudied. Here, we modeled the incorrect timing of physical activity in nightshift workers in male Wistar rats, by restricting running wheel access to the innate inactive (light) phase (LR). Controls included no wheel access (NR); access only during the innate active (dark) period (DR); or unrestricted (ad libitum) access (ALR). LR did not shift the phase of the muscle or liver clock, but dampened the muscle clock amplitude. As our previous study demonstrated that light-phase restricted feeding did shift the liver clock, but made the muscle clock arrhythmic, we next combined the time restriction of wheel and food access to either the light phase (LRLF) or dark phase (DRDF). LRLF produced a ∼12 h shift in the majority of clock gene rhythms in both skeletal muscle and liver. On the other hand, DRDF was most effective in reducing body weight and the accumulation of fat mass. Therefore, in order to shift the muscle clock in male Wistar rats, synergy between the timing of feeding and physical activity is necessary. These findings may contribute to further improve the design of lifestyle strategies that try to limit metabolic misalignment caused by circadian disruption.

HDAC5 controls a hypothalamic STAT5b-TH axis, the sympathetic activation of ATP-consuming futile cycles and adult-onset obesity in male mice

With age, metabolic perturbations accumulate to elevate our obesity burden. While age-onset obesity is mostly driven by a sedentary lifestyle and high calorie intake, genetic and epigenetic factors also play a role. Among these, members of the large histone deacetylase (HDAC) family are of particular importance as key metabolic determinants for healthy ageing, or metabolic dysfunction. Here, we aimed to interrogate the role of class 2 family member HDAC5 in controlling systemic metabolism and age-related obesity under non-obesogenic conditions. Starting at 6 months of age, we observed adult-onset obesity in chow-fed male global HDAC5-KO mice, that was accompanied by marked reductions in adrenergic-stimulated ATP-consuming futile cycles, including BAT activity and UCP1 levels, WAT-lipolysis, skeletal muscle, WAT and liver futile creatine and calcium cycles, and ultimately energy expenditure. Female mice did not differ between genotypes. The lower peripheral sympathetic nervous system (SNS) activity in mature male KO mice was linked to higher dopaminergic neuronal activity within the dorsomedial arcuate nucleus (dmARC) and elevated hypothalamic dopamine levels. Mechanistically, we reveal that hypothalamic HDAC5 acts as co-repressor of STAT5b over the control of Tyrosine hydroxylase (TH) gene transactivation, which ultimately orchestrates the activity of dmARH dopaminergic neurons and energy metabolism in male mice under non-obesogenic conditions.

Plant-based diets-impacts of consumption of little or no animal-source foods on human health.

The world, in 2024, faces both climate and biodiversity crises, and the food system does contribute significantly to these crises. For some, the solution is simple - intakes of animal source foods (ASFs) should be considerably reduced, and consumption of plant-source foods (PSFs) should be greatly increased. Advocates for such a dietary transformation express confidence that plant-based diets will not only benefit planetary health, but will provide nutrient adequacy for all, and will also result in considerable protection from chronic non-communicable diseases (NCDs). However, as described in this perspective, the dramatic reductions in ASFs, entailed by many plant-based diets, will worsen already prevalent micronutrient and protein deficiencies. The protections provided by plant-based diets against NCDs appear to be more strongly associated with reduced intakes of calories and salt, and increased intakes of fruit, vegetables, nuts and whole grains, rather than with reduced intakes of ASFs. Any possible absolute adverse effects of red and processed meat consumption on NCDs are very small and uncertain. Other ASFs either appear to have no impact on NCDs (poultry meat and eggs), or are associated with protections against obesity, cardiovascular events, brain disorders and some cancers (seafood and dairy). Rigorous randomized controlled trials of all newly proposed environmentally-protective plant-based diets are required, so as to provide clear-cut evidence of micronutrient and protein adequacy, with or without, supplementation, fortification and/or biofortification. In the meantime, dietary guidelines should advise moderating excessive consumption, rather than substantially limiting or excluding ASFs from the human diet.

Recent Research on the Human Biology of Pastoralists.

Despite encroachment by agricultural systems and globalization, pastoral nomads maintain a robust presence in terms of numbers and subsistence activity. At the same time, increasing concern about climate change has promoted awareness that increased climatic fluctuation may push pastoral population past their capacity for resilience. The response of pastoralists to climate change has important implications for our evolutionary past and our increasingly problematic future. Yet, pastoralists have received less explicit attention than foragers as populations under consistent selective constraints including limited caloric intake, high levels of habitual activity, and high disease burdens. Additional factors include exposure to cold and high temperatures, as well as high altitude. Over the last 20 or so years, the use of new techniques for measuring energetics, including actigraphs and doubly labeled water have built on existing noninvasive sample collection for hormones, immune markers and genes to provide a more detailed picture of the human biology of pastoral populations. Here I consider recent work on pastoralists from Siberia and northern Europe, Africa, Asia, and South America. I survey what is known about maternal milk composition and infant health, childhood growth, lactase persistence, and adult energy expenditure and lactase persistence to build a picture of the pastoralist biological response to environmental conditions, including heat, cold, and high altitude. Where available I include information about population history because of its importance for selection. I end by outlining the impact of milk consumption and climate over the human life cycle and make suggestions for further research.

AWARENESS OF USAGE THE ARTIFICIAL SWEETENERS IN FOOD BY DIFFERENT POPULATION IN NORTH MACEDONIA

The artificial sweeteners (AS) are popular low-calorie substances used as sugar substitutes, providing strong sweetening effects without adding sugar and energy to the diet. The most popular AS are aspartame, saccharin, and acesulfame K. The aim of this study is to investigate the awareness and knowledge on the usage and health effects of the artificial sweeteners in food products in North Macedonia. Therefore, an online survey was conducted, distributed through Forms media platform on different age population, completed by 392 participants aged 12 years and above, where 69 % were at the age of 30 - 64 old. According to the obtained results, 6 % of respondents do not know what AS are, while 23 % are partially familiar with them. Moreover, 19 % of the respondents do not know how to recognize the additives on the product declarations at all. On the question if the respondents could list which artificial sweeteners they know, 43 % did not know how to answer, and 28 % gave a partially correct or incorrect answer. Also, 35 % of respondents answered that they use artificial sweeteners in order to reduce the calorie intake. Regarding the risk of consuming large amounts of AS in the diet, 15 % of respondents are not aware, and 36 % are partially aware. The results suggest that it is necessary to develop effective strategies for greater education, information and awareness of consumers, about the usage of AS in their diet, as well as about the advantages and risks of their intake.

Effects of Gossypetin on Glucose Homeostasis in Diet-Induced Pre-Diabetic Rats.

Natural flavonoids exert many potential health benefits, including anti-hyperglycaemic effects. However, the effects of gossypetin (GTIN) on glucose homeostasis in pre-diabetes have not yet been investigated. This study examined the effects of GTIN on key markers of glucose homeostasis in a diet-induced pre-diabetic rat model. Pre-diabetes was induced by allowing the animals to feed on a high-fat high-carbohydrate (HFHC) diet supplemented with 15% fructose water for 20 weeks. Following pre-diabetes induction, the pre-diabetic animals were sub-divided into five groups (n = 6), where they were either orally treated with GTIN (15 mg/kg) or metformin (MET) (500 mg/kg), both with and without dietary intervention, over a 12-week period. The results demonstrated that animals in the untreated pre-diabetic (PD) control group exhibited significantly higher fasting and postprandial blood glucose levels, as well as elevated plasma insulin concentrations and increased homeostatic model assessment for insulin resistance (HOMA2-IR) index, relative to the non-pre-diabetic (NPD) group. Similarly, increased caloric intake, body weight and plasma ghrelin levels were observed in the PD control group. Notably, these parameters were significantly reduced in the PD animals receiving GTIN treatment. Additionally, glycogen levels in the liver and skeletal muscle, which were disturbed in the PD control group, showed significant improvement in both GTIN-treated groups. These findings may suggest that GTIN administration, with or without dietary modifications, may offer therapeutic benefits in ameliorating glucose homeostasis disturbances associated with the PD state.

The evolution of animal-based dietary structure has contributed to the increase of healthcare expenditures in China

The trends of diversified diets in China have generated a growing number of nutritional health problems, and healthcare investment is bearing a large burden from the diets, hindering the economic progress of the country and its residents toward affluence. This study linked the evolution of the Chinese dietary structure to changes in health expenditures and predicts future dietary patterns and their impact on health costs over the next 30 years. We found that in the past 30 years, the Chinese dietary structure has shifted towards a nutritional surplus type, and the structure of health expenditures has also shown a trend of two increases and one decrease. The consumption of plant-based foods is significant correlated with lower health expenditures, and animal-based foods show a significant impact on increase of health expenditures. Among nutrients, fat is significant correlated with increased health expenditures, whereas calorie intake is significant correlated with lower health expenditures. By 2030, the Chinese dietary structure will still evolve to a high-protein and high-fatty type. This shift will result in a decrease in per capita healthcare expenditure by 41.66 yuan and increases in household, state, personal, and total healthcare expenditures by 76.83 yuan, 18.76 billion yuan, 95.28 billion yuan, and 17.67 billion yuan, respectively. These findings demonstrate that adjusting dietary structures will bring the dual benefits of improved national health status and a favorable cycle of health expenditures.

Effects of dietary interventions and intermittent fasting on HDL function in obese individuals with T2DM: a randomized controlled trial

BackgroundCardiovascular disease represents a significant risk factor for mortality in individuals with type 2 diabetes mellitus (T2DM). High-density lipoprotein (HDL) is believed to play a crucial role in maintaining cardiovascular health through its multifaceted atheroprotective effects and its capacity to enhance glycemic control. The impact of dietary interventions and intermittent fasting (IF) on HDL functionality remains uncertain. The objective of this study was to assess the effects of dietary interventions and IF as a strategy to safely improve glycemic control and reduce body weight on functional parameters of HDL in individuals with T2DM.MethodsBefore the 12-week intervention, all participants (n = 41) of the INTERFAST-2 study were standardized to a uniform basal insulin regimen and randomized to an IF or non-IF group. Additionally, all participants were advised to adhere to dietary recommendations that promoted healthy eating patterns. The IF group (n = 19) followed an alternate-day fasting routine, reducing their calorie intake by 75% on fasting days. The participants’ glucose levels were continuously monitored. Other parameters were measured following the intervention: Lipoprotein composition and subclass distribution were measured by nuclear magnetic resonance spectroscopy. HDL cholesterol efflux capacity, paraoxonase 1 (PON1) activity, lecithin cholesterol acyltransferase (LCAT) activity, and cholesterol ester transfer protein (CETP) activity were assessed using cell-based assays and commercially available kits. Apolipoprotein M (apoM) levels were determined by ELISA.ResultsFollowing the 12-week intervention, the IF regimen significantly elevated serum apoM levels (p = 0.0144), whereas no increase was observed in the non-IF group (p = 0.9801). ApoM levels correlated with weight loss and fasting glucose levels in the IF group. Both groups exhibited a robust enhancement in HDL cholesterol efflux capacity (p < 0.0001, p = 0.0006) after 12 weeks. Notably, only the non-IF group exhibited significantly elevated activity of PON1 (p = 0.0455) and LCAT (p = 0.0117) following the 12-week intervention. In contrast, the changes observed in the IF group did not reach statistical significance.ConclusionsA balanced diet combined with meticulous insulin management improves multiple metrics of HDL function. While additional IF increases apoM levels, it does not further enhance other aspects of HDL functionality.Trial registrationThe study was registered at the German Clinical Trial Register (DRKS) on 3 September 2019 under the number DRKS00018070.Graphical

Spirulina supplementation and circuit resistance training (CRT) reduce serum asprosin and appetite and improve energy balance in men with obesity and overweight.

The present study aimed to investigate the effects of 8 weeks spirulina supplementation and circuit resistance training (CRT) on asprosin, appetite, and energy balance in men with obesity and overweight. The study comprised a single-blind randomized controlled trial. Sixty men with obesity and overweight (BMI > 25) were selected and randomly divided into four equal groups (n = 15 each) of training plus spirulina, training plus placebo, spirulina, and placebo. The participants of the training groups performed 12 movements with 40-90% maximal repetition (three sessions per week) and the supplemental groups consumed 1000mg of spirulina per day for 8 weeks. Asprosin, appetite using visual analog scales, calorie intake, energy expenditure, and body composition were measured before and after the intervention. To analyze the data, the paired sample t-test, analysis of covariance, Bonferroni post-hoc, and Pearson correlation tests were employed using SPSS (version 20) at a significance level of p < 0.05. After the intervention, asprosin level (P = 0.015, P = 0.015, and P = 0.020, respectively), weight (P < 0.001, P < 0.001, and P < 0.001, respectively), calorie intake (P = 0.015, P = 0.011, and P = 0.004, respectively), and hunger (P = 0.011, P = 0.015, and P = 0.015, respectively) declined in the training plus spirulina, training plus placebo, and spirulina groups (p < 0.05). In addition, energy expenditure (P = 0.012 and P = 0.015, respectively) and fullness (P = 0.015 and P = 0.011, respectively) increased in the training plus spirulina and training plus placebo groups. The mean changes of the research indicators in the training plus spirulina group were significantly more than those of the other groups (p < 0.001). It was shown that 8 weeks of CRT and spirulina supplementation decreases the level of asprosin and improves appetite and energy balance in men with obesity and overweight.

Average Carbohydrate and CaLoric Intake of Patients with Type-2 diabetes at a tertiary care hospital in Pakistan: ACCLIP study.

Type-2 Diabetes Mellitus (T2DM) is one of the most common chronic non-communicable diseases and a serious health issue worldwide because of its rising prevalence amongst the young adults. Dietary diversity, rapid economic development and sedentary lifestyle are amongst the common factors contributing for the rapid rise of diabetes. Our objective was to assess the average carbohydrate (CHO) and caloric consumption and its association with obesity and disease status in patients with Type-2 diabetic patients in an outpatient setting. This study was performed at an outpatient department (OPD), of Hayatabad Medical Complex, Peshawar. Patients with T2DM were interviewed who completed dietary assessment using 24 hours dietary recall method. A total of 150 patients with Type-2 diabetes were interviewed. The mean carbohydrate intake was 400.3±106 mg/day, out of which 43.3 % participant's had carbohydrate intake above recommendations. The mean energy intake for all participants was 2504.5±587.4 Kcal/day. Majority of the participants were overweight and obese with mean BMI of 28kg/m2 ± 4.4. There was no significant difference in energy and carbohydrate intake between male and female participants. Majority of Pakistani patients with Type-2 diabetes consume foods rich in carbohydrate as well as have high caloric value. These finding were more in patients with no formal education compared to those who were well educated with a degree.

Gender Differences in Normative Misperceptions of Food and Alcohol Disturbance Among a Multi-Site Sample of College Students

Background: Engagement in food and alcohol disturbance (FAD; e.g., restricting caloric intake in the context of using alcohol to quicken/increase intoxication [FAD-intoxication] and/or to offset calories consumed from alcohol [FAD-calories]) confers risk to college students. Much research suggests that students overestimate the frequency of high-risk drinking among their peers, leading to greater participation in personal high-risk drinking. However, limited work has examined social norms related to FAD and their association with FAD behaviors. Objectives: The present study investigated: (a) whether normative misperceptions exist for FAD, (b) whether FAD norms are associated with FAD behaviors, and (c) whether gender moderates the association between FAD norms and FAD behaviors. Participants were 1,499 college students from six universities who consumed alcohol in the last month and identified as a woman or man. A plurality of participants identified as being White, non-Hispanic (59.5%) and female (68.1%), with a mean age of 19.66 (SD = 2.09) years. Results: Analyses revealed that students overestimated the frequency and approval of both FAD-intoxication and FAD-calories behaviors among their same-gender peers. Notably, these misperceptions were greater for FAD participators compared to FAD abstainers. Moreover, the associations between FAD norms and FAD behaviors were generally stronger for women compared to men. Conclusions: Our preliminary findings identify social norms as a potential target for interventions aiming to reduce FAD among college students. Further, our results provide preliminary evidence that college women, especially those who engage in FAD, may reap the greatest benefit from interventions targeting normative misperceptions (e.g., personalized normative feedback) related to FAD.

Laxative Properties of Microencapsulated Oleic Acid Delivered to the Distal Small Intestine in Patients with Constipation after Bariatric Surgery or Treatment with Glucagon-Like- Peptide 1 Analogues

BackgroundConstipation is prevalent after bariatric surgery and glucagon-like-peptide 1 (GLP-1) analogues. Increasing fat content in the distal small intestine and colon can enhance colonic peristalsis, potentially alleviating symptoms of constipation.AimWe investigated whether oleic acid can ameliorate constipation in patients undergoing bariatric surgery or receiving GLP-1 analogues.MethodologyFourteen adults with chronic constipation according to Rome IV criteria following bariatric surgery or GLP-1 analogues were on stable treatment for constipation for more than 4 weeks. This randomized double-blind crossover trial compared microcapsules containing 21.25 g of oleic acid delivered in the distal small intestine or the stomach. The primary outcome was changed in the number of bowel motions over 24 h. Exploratory endpoints included alterations in straining, diarrhoea, faecal leakage over 24 h and hunger, fullness, nausea and calorie intake for the 3 h after ingesting the microcapsules.FindingsReceiving oleic acid into the distal small intestine increased number of bowel movements per day (2.5 vs 1.1, p = 0.009) and caused softer stool consistency (p = 0.03). 9/14 of the control group passed motions and 13/14 of the intervention group passed motions in 24 h (p = 0.059). No significant differences were observed in straining (p = 0.65), rapid bowel movements (p = 0.08), accidental leakage (p = 0.32), hunger, fullness, nausea or food intake between the groups (all p > 0.05). There were no disparities in safety profile between groups.ConclusionMicrocapsules containing oleic acid delivered to the distal small intestine appear to be a safe and effective relief from chronic constipation in patients undergoing bariatric surgery and/or receiving GLP-1 analogues.Graphical

Safety and impact of the Mediterranean diet in patients with chronic kidney disease: a pilot randomized crossover trial.

Emerging evidence highlights the potential advantages of the Mediterranean diet (MD) in preserving kidney function and slowing chronic kidney disease (CKD) progression. However, interventional studies on the MD are scarce in East Asian populations. This randomized crossover trial aimed to assess the safety and short-term impact of the Mediterranean Proper Optimal Balance (MEDi-POB) diet in Korean patients with stage 3-4 CKD. Kidney function was assessed using the estimated glomerular filtration rate, which was calculated using the CKD Epidemiology Collaboration equation. Fifty patients with CKD were randomly assigned to two groups, each starting with a different 4-week intervention, followed by a 4-week washout period, followed by a switch to the other 4-week intervention. During the MEDi-POB intervention, patients received home delivery of meals twice daily, 5 days a week, while the control intervention comprised a conventional diet. Forty-six patients successfully completed the entire 12-week trial. Paired t-tests were conducted to assess mean differences between the two groups. A linear mixed model was used to adjust for sequence and period. Dietary fat, fiber, and niacin intake were significantly higher following the MEDi-POB diet than following the control diet (p = 0.001 for fat, p < 0.001 for fiber, and p = 0.007 for niacin). The MEDi-POB diet also yielded slightly increased total CO2 levels (p = 0.043), indicating effective management of metabolic acidosis. Conversely, sodium and copper intake were significantly lower with the MEDi-POB diet (p = 0.032 and p = 0.037, respectively). Caloric intake increased, but body mass index slightly decreased from baseline after consuming the MEDi-POB diet. Dietary potassium intake exhibited a non-significant increase (p = 0.053), and no significant changes in serum (p = 0.883) and urine potassium levels (p = 0.087) occurred. Kidney function remained well-preserved following the MEDi-POB diet. These results indicate that the MEDi-POB diet is safe even in patients with advanced CKD, as it does not adversely affect serum and urine potassium levels and helps maintain kidney function.

The effects of Cannabis sativa and cannabinoids on the inhibition of pancreatic lipase – An enzyme involved in obesity

IntroductionObesity is a chronic noncommunicable disease characterized by excessive body fat that can have negative health consequences. Obesity is a complex disease caused by a combination of genetic, environmental, and lifestyle factors. It is characterized by a discrepancy between caloric intake and expenditure. Obesity increases the risk of acquiring major chronic diseases, including heart disease, stroke, cancer, and Type 2 diabetes mellitus (T2DM). Currently, the inhibition of pancreatic lipases (PL) is a promising pharmacological therapy for obesity and weight management. In this study, the inhibition of pancreatic lipase by Cannabis sativa (C. sativa) plant extract and cannabinoids was investigated. MethodsThe inhibitory effect was assessed using p-nitrophenyl butyrate (pNPB), and the results were obtained by calculating the percentage relative activity and assessed using one-way analysis of variance (ANOVA). Kinetic studies and spectroscopy techniques were used to evaluate the mode of inhibition. Diet-induced; and diabetic rat models were studied to evaluate the direct effects of C. sativa extract on PL activity. ResultsKinetic analyses showed that the plant extracts inhibited pancreatic lipase, with tetrahydrocannabinol (THC) and cannabinol (CBN) being the potential cause of the inhibition noted for the C. sativa plant extract. CBN and THC inhibited the pancreatic lipase activity in a competitive manner, with the lowest residual enzyme activity of 52 % observed at a 10 μg/mL concentration of CBN and 39 % inhibition at a 25 μg/mL concentration of THC. Circular dichroism (CD) spectroscopy revealed that the inhibitors caused a change in the enzyme's secondary structure. At low concentrations, THC showed potential for synergistic inhibition with orlistat. C.sativa treatment in an in vivo rat model confirmed its inhibitory effects on pancreatic lipase activity. ConclusionThe findings in this study provided insight into the use of cannabinoids as pancreatic lipase inhibitors and the possibility of using these compounds to develop new pharmacological treatments for obesity.

Investigating the Impact of Climate Change Impacts on Direct-seeded Rice Production in Middle Gujarat Using the InfoCrop-rice Model

Rice (Oryza sativa L.) is a global food staple, essential for human nutrition and calorie intake, particularly in low- and middle-income countries. This study assesses the impact of climate change on direct-seeded rice (DSR) production in Middle Gujarat (India) using the InfoCrop-Rice model. The study evaluates potential climate scenarios under Representative Concentration Pathways (RCP) 4.5 and RCP 8.5, focusing on projected changes in temperature, rainfall, and sunshine hours, and their effects on rice yield and phenology. Field data from Kharif 2023 were used to calibrate the model, which projected significant increases in maximum and minimum temperatures, variable changes in rainfall, and consistent reductions in sunshine hours. By 2100, maximum temperatures are expected to rise by up to 6°C under RCP 8.5, and minimum temperatures could increase by as much as 7.5°C. Rainfall projections show high variability, with potential reductions and increases depending on the scenario and time period. Sunshine hours are projected to decline by approximately 6.6% under both RCP scenarios. The model simulations indicate a notable decline in rice yields, with reductions ranging from 18% to 36% by 2100. These results underscore the severe impact of climate change on DSR productivity. The study highlights the need for adaptive strategies, including improved water management, resilient crop varieties, and sustainable agricultural practices, to mitigate the adverse effects of climate change and ensure the sustainability of direct seeded rice production in Middle Gujarat.

Age-based challenges to type 1 diabetes management in the pediatric population.

Type 1 diabetes is rising in the pediatric population, affecting approximately 1.2 million children and adolescents globally. Its complex pathogenesis involves the interaction between genetic predisposition and environmental factors, leading to T cell-mediated destruction of insulin-producing pancreatic beta-cells. This destruction results in insulin insufficiency and hyperglycemia. Hence, managing type 1 diabetes requires a comprehensive approach that includes various aspects such as blood glucose monitoring, insulin therapy, carbohydrate counting, caloric intake monitoring, considering family habits and food preferences, planning daily schedules, and incorporating physical activity. Children with type 1 diabetes encounter age-specific challenges in disease management that may exacerbate the risk of metabolic complications and adverse health outcomes. These risk factors may be neurological, physiological, behavioral, psychological, or social, complicate management and necessitate tailored approaches for effective care. Regardless of the age group, primary caregivers have a high responsibility to maintain optimal glycemic control, including monitoring diet, daily activity, and administering insulin. By reviewing research on the challenges faced by pediatric patients with type 1 diabetes, we summarized key insights aimed at developing targeted interventions and support systems that enhance diabetes management and improve health outcomes in this vulnerable population.
