RESUMO

Ketogenic diet therapy (KDT) is well established for the treatment of early epileptic encephalopathies and specific aetiologies; however, the impact on growth in infancy remains controversial. Our aim was to examine the influence of early KDT on growth velocity and height percentiles completing two tasks. First, we systematically reviewed the literature on growth in infants younger than 12 months. Second, we analysed data from our prospective database, including infants <12 months (n = 63) treated with KDT. The literature review (n = 7) remains descriptive and includes growth percentiles and z-scores as growth velocity was not described. Studies up to 2010 used fasting, calorie restrictions, and ratios >3:1. In individual cases, significant growth delays were found; other authors did not find any changes in growth parameters. Study endpoints in our own cohort included z-scores of growth velocity, standard deviation (SD) of height, weight, BMI, deviation from individual height percentile, and daily macronutrient intake. The median z-score of growth velocity was 1.03 (first year of life). After three months, median daily intake of protein and energy was 1.68 g/kg and 85 kcal/kg. Until the age of one year, neither growth velocity nor individual growth percentiles decreased. Infants showed distinct growth improvements at three months, likely due to continuous nutritional monitoring and reduction in seizures. In the second year of life, z-scores of growth velocity decreased in patients still receiving KDT (from 1.03 at 12 months to -1.5 at 24 months). Furthermore, younger age at epilepsy onset and at KDT start correlated with slower growth velocities in the first year of life. With appropriate nutritional intake and monitoring, KDT does not reduce growth in the first year of life. Future directions might be to study the impact of KDT on growth velocity and growth hormones throughout childhood.

RESUMO

Background: The effectiveness of dietary therapy to induce remission of eosinophilic esophagitis (EoE) has been evaluated over the last decades and summarized in meta-analyses. Choosing the dietary modality, identifying the most suitable patients, and implementing specific prerequisites are essential to ensure long-term success. Summary: Impractical exclusive elemental diets provided the highest remission rates in EoE; however, they are not recommended due to their numerous disadvantages and detrimental effects on patient quality of life. Allergy testing-guided diets for EoE are limited; their insufficient effectiveness and low reproducibility are due to poor accuracy of skin or serum test results in identifying EoE food triggers. Initial experiences with a six-food elimination diet have provided evidence of high and predictive effectiveness rates and paved the way for less restrictive and more efficient step-up approaches, including four-food, two-food, and most recently, milk elimination diets. Dietary treatment for EoE is challenging for patients and families and requires certain skills to ensure success in the short and long term. Key Messages: The selection of appropriate patients is essential to ensure the success of and long-term adherence to dietary treatment of EoE. As normal triggers for EoE are commonly found in the staple diet, it is important to ensure adequate nutritional substitutes to avoid nutrient deficiency risks when long-lasting feeding difficulties or extensive restrictions are present. Specialized facilities in dietary therapy should adopt patient-centered and personalized approaches in order to provide timely monitoring and support for complex cases.

RESUMO

Obesity stands out as a primary risk factor for diabetes. Attaining healthy weight loss, especially reducing body fat, is important in managing prediabetes and preventing progression to full diabetes and its co-morbidities. This study examined the effects of personalized nutrition therapy (PNT) combined with continuous glucose monitoring (CGM) on body weight and composition in individuals with prediabetes. A total of 30 individuals with prediabetes who were overweight or obese were assigned randomly to either the treatment, observed CGM data plus PNT, or the control group which was blinded to their blood glucose results throughout the study. Both groups were provided with dietary recommendations for calorie intake and macronutrient distribution, coupled with personalized goal setting for glucose control and healthy eating, without any specific emphasis on weight reduction or changes in physical activity. Regular visits were scheduled every 10 days to perform measurements and replace CGMs. Data were analyzed using General Linear Model with repeated measures. Over the 30-day follow-up period, both groups experienced significant reductions in weight and fat mass. The treatment group exhibited two-fold greater reductions in both weight and fat mass, a significant decrease in carbohydrate intake, and a significant increase in time spent on physical activitycompared to the control group. In addition, compliance was notably higher in the treatment group. These findings indicate that overweight or obese individuals with prediabetes can achieve weight loss and improved body composition through personalized education for glucose control, without exclusively emphasizing weight loss as the primary objective. Additionally, the real-time feedback provided by CGM enhances these improvements.

RESUMO

Excess body weight in pediatric patients and the resulting dyslipidemia, if left untreated, are a serious risk factor for cardiovascular disease in young adults. Despite this, there is still no effective and validated nutritional strategy for the treatment of overweight/obesity and comorbid dyslipidemia in children and adolescents. A low-glycemic index (LGI) diet may be recommended, but evidence for its effectiveness in the pediatric population is limited. The aim of this study was to evaluate the effectiveness of nutritional intervention in children and adolescents with excess body weight and dyslipidemia. The study was conducted in patients aged 8-16 with overweight or obesity and lipid disorders (n = 64), of which 40 participants who completed the entire 8-week study were included in the analysis. Patients were randomly selected and allocated to one of the two dietary groups: the LGI diet or the standard therapy (ST) diet. Both diets were based on the principal recommendation of Cardiovascular Health Integrated Lifestyle Diet-2 (CHILD-2). This study showed that both LGI and ST diets were equally beneficial in reducing body weight, body fat, blood pressure, total cholesterol (TC), and triglyceride (TG) levels. The LGI diet, compared to the ST diet, was less effective in reducing blood TG levels but more effective in reducing diastolic blood pressure (DBP). Therefore, the choice of the type of diet in the treatment of children and adolescents with excess body weight and dyslipidemia may be individual. However, it should be based on the recommendation of CHILD-2. Further long-term, larger-scale studies are needed.

RESUMO

BACKGROUND: The aims of this study were to develop and evaluate a high/low-emulsifier diet and compare emulsifier content with preclinical studies that have associated Crohn's disease with emulsifiers. METHODS: Supermarkets were audited with a seven-day high- (HED) and low-emulsifier diet (LED) meal plan developed. The emulsifier content of food was sought from food manufacturers, compared to acceptable daily intake (ADI), and doses were provided in trials. Nutritional composition analysis was completed. Healthy adults ate these diets for seven days in a randomized single-blinded cross-over feeding study to assess palatability, tolerability, satiety, food variety, dietary adherence, blinding and the ease of following the meal plan via visual analogue scale. RESULTS: A database of 1680 foods was created. There was no difference in nutritional content between the HED and LED, except HED had a higher ultra-processed food content (p < 0.001). The HED contained 41 emulsifiers, with 53% of the products able to be quantified for emulsifiers (2.8 g/d), which did not exceed the ADI, was similar to that in observational studies, and was exceeded by doses used in experimental studies. In ten participants, diets were rated similarly in palatability-HED mean 62 (5% CI 37-86) mm vs. LED 68 (54-82) mm-in tolerability-HED 41 (20-61) mm vs. LED 55 (37-73) mm-and in satiety HED 57 (32-81) mm vs. LED 49 (24-73) mm. The combined diets were easy to follow (82 (67-97) mm) with good variety (65 (47-81)) and excellent adherence. CONCLUSION: Nutritionally well-matched HED and LED were successfully developed, palatable and well tolerated.

RESUMO

Crohn's disease is a type of inflammatory bowel disease (IBD) that typically presents in the second or third decade of life. There are various pharmaceutical therapies that have been developed to treat the disease's symptoms. However, some patients still do not find relief with these medications and turn to other therapies such as diet modification. The underlying cause of Crohn's disease involves multiple factors such as uncontrolled inflammation and several genetic variants. While most current medication therapies control the symptoms that occur due to this uncontrolled level of inflammation, an anti-inflammatory diet (AID) may actually lower the level of inflammation in the gut and therefore reduce the amount of disease symptoms in Crohn's disease. Some such diets include the IBD-AID, Crohn's disease exclusion diet, and the Groningen AID (GrAID). This report describes a case of treatment-resistant Crohn's disease in a patient who was given all categories of pharmaceutical therapies including prednisone, budesonide, sulfasalazine, olsalazine, 6-mercaptopurine, methotrexate, mesalamine, and adalimumab. These only gave temporary relief of symptoms and eventually failed for various reasons including allergic reaction, insufficient symptom control, and antibody formation against the medication. This prompted the patient to independently research AIDs instead. In conclusion, for patients whose disease is refractory to different treatments, or who develop antibodies to the medication, AIDs may offer a solution to reduce disease symptoms and progression. Education of healthcare professionals and patients alike is vital in order for Crohn's patients to gain the benefits from dietary therapy.

RESUMO

Type 2 Diabetes mellitus (T2DM) is one of the oldest known chronic diseases, characterized by elevated fasting blood sugar (FBS). T2DM is a metabolic disorder that can distort the activities of multiple physiological systems, including the reproductive system. Although different drugs have been designed for managing this disorder, these drugs have been reported to have negative side effects. Hence, this study was designed to explore the possible synergistic effect of vitamin D and exercise on T2DM-induced testicular dysfunction. Thirty-six male Wistar rats were randomized into six (6) groups: control, diabetes untreated, diabetes treated with 1000 IU/kg of vitamin D, diabetes treated with 5 min/day of physical exercise, diabetes treated with vitamin D and exercise, diabetes treated with 180 mg/kg of metformin. T2DM induction led to a significant increase in FBS, lactate, and lactate dehydrogenase, and was reversed by vitamin D supplementation and exercise. Also, vitamin D and exercise synergistically blunted T2DM-induced oxido-inflammatory response evidenced by a significant decrease in testicular malondialdehyde, interleukin 1ß, interleukin 6, and tumor necrosis factor alpha, and an increase in superoxide dismutase, catalase, glutathione peroxidase, and interleukin 10. These events were associated with a decrease in T2DM-induced increase in XO, UA, and Nf-κb and an increase in T2DM-induced decrease in Nrf2. Also, vitamin D and EX reversed the observed impairment in sperm quality and testicular histology following T2DM-induction. This study revealed the synergistic effect of vitamin D and exercise on T2DM-induced testicular dysfunction.

RESUMO

To evaluate perinatal outcomes and risk factors for large for gestational age (LGA; birth weight over 90 percentile) in gestational diabetes diagnosed before 24 gestational weeks and treated with diet therapy alone until delivery (Diet Early gestational diabetes mellitus (Diet Early GDM)), we assessed the maternal characteristics and perinatal outcomes of patients with early GDM (n = 309) and normal glucose tolerance (NGT; n = 309) at Keio University Hospital. The gestational weight gain (GWG) expected at 40 weeks was significantly lower in the Diet Early GDM group than in the NGT group. The Diet Early GDM group exhibited a significantly lower incidence of low birth weight (<2500 g) and higher Apgar score at 5 min than the NGT group. Multiple logistic regression analysis revealed that the pre-pregnancy body mass index and GWG expected at 40 weeks were significantly associated with LGA for Diet Early GDM. No differences were observed in random plasma glucose levels in the first trimester, 75 g oral glucose tolerance test values, and initial increase or subsequent decrease between the two groups. Dietary early GDM did not exhibit a worse prognosis than NGT. To prevent LGA, it might be important to control maternal body weight not only during pregnancy but also before conception.

RESUMO

Many patients diagnosed with cancer adopt dietary changes and supplement use, and a growing body of evidence suggests that such modifications can affect outcomes to cancer therapy. We sought to assess the prevalence of these practices and the surrounding physician-patient dialogue among patients with metastatic renal cell carcinoma. An online survey was administered by Kidney Cancer Research Alliance (KCCure), interrogating dietary modification patterns, supplement usage, out-of-pocket expenditure related to supplements, and patients' views toward alternative medicine practices. Patients with metastatic renal cell carcinoma receiving combination therapy were actively solicited. In total, 289 unique responses were collected. The most common first-line treatments were nivolumab/ipilimumab (32.4%) and axitinib/pembrolizumab (13.1%). Within the cohort, 147 (50.9%) started using supplements following diagnosis of renal cell carcinoma; the most utilized supplements were probiotics, cannabidiol (CBD) oil/marijuana, and Vitamin C, reported by 70 (47.6%), 61 (41.4%), and 54 (36.7%), respectively. Dietary modifications following cancer diagnosis were reported by 101 (34.9%) respondents, of which 19.8% followed the Mediterranean diet and 18.8% adopted a ketogenic diet. Most respondents (71.3%) noted that they consistently report supplement usage to their physicians. A substantial proportion of patients with metastatic renal cell carcinoma utilize dietary modification and supplements as an adjunct to antineoplastic therapy. Considering the widespread adoption of these practices and the reported effects on cancer treatment, it is crucial for healthcare providers to engage in discussions with patients regarding supplement use.

RESUMO

BACKGROUND: Patients with dialysis-dependent kidney failure and treated for hyperphosphatemia receive a combination of dietary advice, phosphate binders and prolonged dialysis. However, research focusing on the challenges patients meet in everyday life addressing diet and medication is sparse. OBJECTIVE: The objective of this study is to explore the everyday challenges patients meet when following treatment for hyperphosphatemia. DESIGN: Interpretive description was the methodological approach. Semistructured in-depth interviews were employed to study the challenges patients experienced. Data were analysed using Braun and Clarke's reflexive thematic analysis. PARTICIPANTS: Patients (n = 14) receiving haemodialysis and treated for hyperphosphatemia from two hospitals in Southern Denmark. FINDINGS: The analysis resulted in one over-arching theme; separation in social gatherings and two subthemes; a new social code, and my food and their food. Participants experienced difficulty integrating diet and medication in daily life, especially at social gatherings. They felt separated from others when special menus were provided for them or struggled when choosing between high and low phosphate-containing food. A new awareness of self and others arose, especially their position among families and friends, and how they presented themselves and their social identity to others. Likewise, a new social code manifested itself, which was difficult to accept. Most participants experienced that diet and medication were accompanied by a moral responsibility of whether to accept prepared food with high phosphorus content or not, which affected commensality. CONCLUSION: Patients were often nonadherent to hyperphosphatemia treatment at social gatherings. Hyperphosphatemia treatment led to new social identities with new social codes, which patients found difficult to accept.

RESUMO

BACKGROUND & AIM: Malnutrition, risk of malnutrition, and risk factors for malnutrition are prevalent among acutely admitted medical patients aged ≥65 years and have significant health-related consequences. Consequently, we aimed to investigate the effectiveness of a multidisciplinary and transitional nutritional intervention on health-related quality of life compared with standard care. METHODS: The study was a block randomized, observer-blinded clinical trial with two parallel arms. The Intervention Group was offered a multidisciplinary transitional nutritional intervention consisting of dietary counselling and six sub-interventions targeting individually assessed risk factors for malnutrition, while the Control Group received standard care. The inclusion criteria were a Mini Nutritional Assessment Short-Form score ≤11, age ≥65 years, and an acute admittance to the Emergency Department. Outcomes were assessed on admission and 8 and 16 weeks after hospital discharge. The primary outcome was the difference between groups in change in health-related quality of life (assessed by the EuroQol-5D-5L) from baseline to 16 weeks after discharge. The secondary outcomes were difference in intake of energy and protein, well-being, muscle strength, and body weight at all timepoints. RESULTS: From October 2018 to April 2021, 130 participants were included. Sixteen weeks after discharge, 29% in the Intervention Group and 19% in the Control Group were lost to follow-up. Compliance varied between the sub-interventions targeting nutritional risk factors and was generally low after discharge, ranging from 0 to 61%. No difference was found between groups on change in health-related quality of life or on well-being, muscle strength, and body weight at any timepoint, neither using the intention-to-treat analysis nor the per-protocol analysis. The protein intake was higher in the Intervention Group during hospitalization (1.1 (Standard Deviation (SD) 0.4) vs 0.8 (SD 0.5) g/kg/day, p = 0.0092) and 8 weeks after discharge (1.2 (SD 0.5) vs 0.9 (0.4) g/kg/day, p = 0.0025). The percentual intake of calculated protein requirements (82% (SD 24) vs 61% (SD 32), p = 0.0021), but not of calculated energy requirements (89% (SD 23) vs 80% (SD 37), p = 0.2), was higher in the Intervention Group than in the Control Group during hospitalization. Additionally, the Intervention Group had a significantly higher percentual intake of calculated protein requirements (94% (SD 41) vs 74% (SD 30), p = 0.015) and calculated energy requirements (115% (SD 37) vs 94% (SD 31), p = 0.0070) 8 weeks after discharge. The intake of energy and protein was comparable between the groups 16 weeks after discharge. CONCLUSION: We found no effect of a multidisciplinary and transitional nutritional intervention for acutely admitted medical patients aged ≥65 years with malnutrition or risk of malnutrition on our primary outcome, health-related quality of life 16 weeks after discharge. Nor did the intervention affect the secondary outcomes, well-being, muscle strength, and body weight from admission to 8 or 16 weeks after discharge. However, the intervention improved energy and protein intake during hospitalization and 8 weeks after discharge. Low compliance with the intervention after discharge may have compromised the effect of the intervention. The study is registered at ClinicalTrials.gov (identifier: NCT03741283).

RESUMO

Background: Low compliance (LC) with lifestyle modification is a very common obstacle in obesity management. The purpose of the current study was to investigate the effectiveness of obesity management according to compliance with a lifestyle-modification program. Methods: The "Change 10 Habits" program was administered four times over 12 weeks. Eighty-seven participants were divided into LC and high compliance (HC) groups for analysis after intervention. Then, to assess the program's effectiveness based on compliance, we conducted t-tests and linear regression modeling. Results: In week 12, the scores of two dietary habits-specifically, "eat three meals regularly, adequate amount" and "do not eat after 9:00 PM"-were significantly higher in the HC group than in the LC group. Changes in leg and total body fat percentages were significantly improved in the HC group (-0.2%±0.3% vs. 0.9%±0.3%, P<0.05; -0.1%±0.3% vs. 1.1%±0.5%, P<0.05, respectively). The body mass index was also significantly lower in the HC group than in the LC group (26.7±1.8 kg/m2 vs. 27.7±2.1 kg/m2, P<0.05) at final follow-up. Finally, the systolic blood pressure, triglyceride, and very-low-density lipoprotein cholesterol values of the HC group also decreased significantly (from 117.9±12.2 to 114.3±15.0 mmHg, P<0.05; from 121.7±74.9 to 105.7±60.9 mg/dL, P<0.05; and from 24.3±15.0 to 21.1±12.2 mg/dL, P<0.05, respectively). Conclusion: HC with the study program effectively improved the dietary habits, body fat composition, blood pressure, and lipid profile of adults with mild obesity.

RESUMO

Purpose: The increasing incidence of nephrolithiasis underscores the need for effective, accessible tools to aid urologists in preventing recurrence. Despite dietary modification's crucial role in prevention, targeted dietary counseling using 24-hour urine collections is underutilized. This study evaluates ChatGPT-4, a multimodal large language model, in analyzing urine collection results and providing custom dietary advice, exploring the potential for artificial intelligence-assisted analysis and counseling. Materials and Methods: Eleven unique prompts with synthesized 24-hour urine collection results were submitted to ChatGPT-4. The model was instructed to provide five dietary recommendations in response to the results. One prompt contained all "normal" values, with subsequent prompts introducing one abnormality each. Generated responses were assessed for accuracy, completeness, and appropriateness by two urologists, a nephrologist, and a clinical dietitian. Results: ChatGPT-4 achieved average scores of 5.2/6 for accuracy, 2.4/3 for completeness, and 2.6/3 for appropriateness. It correctly identified all "normal" values but had difficulty consistently detecting abnormalities and formulating appropriate recommendations. The model performed particularly poorly in response to calcium and citrate abnormalities and failed to address 3/10 abnormalities entirely. Conclusions: ChatGPT-4 exhibits potential in the dietary management of nephrolithiasis but requires further refinement for dependable performance. The model demonstrated the ability to generate personalized recommendations that were often accurate and complete but displayed inconsistencies in identifying and addressing urine abnormalities. Despite these limitations, with precise prompt design, physician oversight, and continued training, ChatGPT-4 can serve as a foundation for personalized medicine while also reducing administrative burden, indicating its promising role in improving the management of conditions such as nephrolithiasis.

RESUMO

The gut microbiota and short chain fatty acids (SCFA) have been associated with immune regulation and autoimmune diseases. Autoimmune kidney diseases arise from a loss of tolerance to antigens, often with unclear triggers. In this review, we explore the role of the gut microbiome and how disease, diet, and therapy can alter the gut microbiota consortium. Perturbations in the gut microbiota may systemically induce the translocation of microbiota-derived inflammatory molecules such as liposaccharide (LPS) and other toxins by penetrating the gut epithelial barrier. Once in the blood stream, these pro-inflammatory mediators activate immune cells, which release pro-inflammatory molecules, many of which are antigens in autoimmune diseases. The ratio of gut bacteria Bacteroidetes/Firmicutes is associated with worse outcomes in multiple autoimmune kidney diseases including lupus nephritis, MPO-ANCA vasculitis, and Goodpasture's syndrome. Therapies that enhance SCFA-producing bacteria in the gut have powerful therapeutic potential. Dietary fiber is fermented by gut bacteria which in turn release SCFAs that protect the gut barrier, as well as modulating immune responses towards a tolerogenic anti-inflammatory state. Herein, we describe where the current field of research is and the strategies to harness the gut microbiome as potential therapy.

RESUMO

The published data on the vitamin status of patients with phenylketonuria (PKU) is contradictory; therefore, this systematic review and meta-analysis evaluated the vitamin status of PKU patients. A comprehensive search of multiple databases (PubMed, Web of Sciences, Cochrane, and Scopus) was finished in March 2024. The included studies compared vitamin levels between individuals diagnosed with early-treated PKU and healthy controls while excluding pregnant and lactating women, untreated PKU or hyperphenylalaninemia cases, control groups receiving vitamin supplementation, PKU patients receiving tetrahydrobiopterin or pegvaliase, and conference abstracts. The risk of bias in the included studies was assessed by the Newcastle-Ottawa scale. The effect sizes were expressed as standardised mean differences. The calculation of effect sizes with 95% CI using fixed-effects models and random-effects models was performed. A p-value < 0.05 was considered statistically significant. The study protocol was registered in the PROSPERO database (CRD42024519589). Out of the initially identified 11,086 articles, 24 met the criteria. The total number of participants comprised 770 individuals with PKU and 2387 healthy controls. The meta-analyses of cross-sectional and case-control studies were conducted for vitamin B12, D, A, E, B6 and folate levels. PKU patients demonstrated significantly higher folate levels (random-effects model, SMD: 1.378, 95% CI: 0.436, 2.320, p = 0.004) and 1,25-dihydroxyvitamin D concentrations (random-effects model, SMD: 2.059, 95% CI: 0.250, 3.868, p = 0.026) compared to the controls. There were no significant differences in vitamin A, E, B6, B12 or 25-dihydroxyvitamin D levels. The main limitations of the evidence include a limited number of studies and their heterogeneity and variability in patients' compliance. Our findings suggest that individuals with PKU under nutritional guidance can achieve a vitamin status comparable to that of healthy subjects. Our study provides valuable insights into the nutritional status of PKU patients, but further research is required to confirm these findings and explore additional factors influencing vitamin status in PKU.

RESUMO

The quality of a mother's diet is important to ensure child growth and development and keep women healthy. This systematic review aimed to identify the outcomes of a carbohydrate-restricted diet during lactation. PubMed, EMBASE, Scopus, Web of Science, and LILACS were searched for studies published between 2012 and 2023; 16 studies were selected, all of them case reports or care series. The carbohydrate restriction described in the papers mainly was ketogenic, low-carb, low-carbohydrate and high-fat, and modified ketogenic diets. The main goal of women undertaking these diets was weight loss, with therapeutic purposes (monitored and supervised by health professionals) in only 2 cases: (1) ketogenic diet therapy for treatment of seizures in the infant and (2) to reduce symptoms of mother's gastroesophageal reflux. Most articles reported that lactating women were hospitalized, experiencing symptoms such as vomiting, muscle weakness, nausea, abdominal pain, general malaise, and fatigue. However, articles did not mention poor outcomes for the infants. Most of the studies in this review were published in the past 3 years, indicating a possible increase in cases of women practicing carbohydrate restriction during lactation for weight loss caused by body dissatisfaction. In conclusion, carbohydrate restriction during lactation may be harmful to the lactating woman and contribute to the state of lactational ketoacidosis, but infant outcomes are mainly a change in feeding patterns. Thus, education on food and nutrition is necessary for this population.

RESUMO

This study aimed to determine whether patients with type 2 diabetes can benefit from a meal plan designed based on diabetes management guidelines to improve blood glucose levels. Participants were divided into intervention and control groups. The intervention group consumed a diabetic diet for 2 weeks, while the control group consumed their normal diet. After 2 weeks, the groups switched their dietary regimens. The participants' demographic and clinical characteristics were evaluated, including factors such as blood pressure, blood lipid levels, weight and waist circumference, blood glucose levels (self-monitored and continuously monitored), nutritional status, and blood-based markers of nutrient intake. The dietary intervention group improved waist circumference, body fat percentage, low-density lipoprotein cholesterol, triglyceride levels, and glucose. The energy composition ratio of carbohydrates and proteins changed favorably, and sugar intake decreased. In addition, the proportion of continuous glucose monitoring readings within the range of 180-250 mg/dL was relatively lower in the intervention group than that of the control group. Meals designed based on diabetes management guidelines can improve clinical factors, including stable blood glucose levels in daily life, significantly decrease the carbohydrate energy ratio, and increase the protein energy ratio. This study can help determine the role of dietary interventions in diabetes management and outcomes.

RESUMO

Introduction: The primary treatment for non-alcoholic fatty liver disease (NAFLD) is modifying lifestyle through dietary or exercise interventions. In recent decades, it has received increasing attention. However, the lack of bibliometric analysis has posed a challenge for researchers seeking to understand the overall trends in this field. Methods: As of February 3rd, 2024, 876 articles on treating NAFLD through diet or exercise therapy from 2013 to 2023 had been retrieved. Two software tools, VOSviewer and CiteSpace, were utilized to analyze the growth of publications, countries, institutions, authors, journals, citations, and keywords. Additionally, the keywords with strong citation burstiness were identified to determine the changes and future trends of research hotspots in this field. Results: China had the highest number of articles, followed by the United States and South Korea. Yonsei University and Nutrients were the institutions and journals with the most significant contributions. Professor Younossi Zobair M, from the United States, is the most prolific author in this field. Through analyzing the keywords, three research hotspots were identified: research on the pathogenesis of NAFLD, research on the treatment modalities of NAFLD, and research on the risk factors and diagnosis methods of NAFLD. In recent years, the research emphasis in this field has changed, suggesting that future research will focus on two frontier keywords: "oxidative stress" and "aerobic capacity." Conclusion: In the past eleven years, the attention in this field was still rising, and the authors, journals, countries and so on had formed a considerable cooperative relationship. There were also many highly influential and productive researchers in this field. It is speculated that new research will continue around "aerobic exercise" and "oxidative stress" in the future.

RESUMO

Objective: To evaluate the outcomes of nutritional intervention on non-alcoholic fatty liver disease parameters, and to determine the reasons for non-compliance with nutritional therapy. METHODS: The interventional study was conducted from May 2020 to October 2022 at the National Institute of Liver and Gastrointestinal diseases, Dow University Hospital, Ojha Campus, Karachi, and comprised patients of either gender aged 18-65 years who had been diagnosed with non-alcoholic fatty liver disease based on abdominal ultrasound. Anthropometrics, physical activity level, and biochemical markers were evaluated at baseline and 6 months after the intervention that involved nutritional assessment, counselling and guidance related to dietary modification and optimisation of physical activity level. The effect of the intervention was evaluated by improvement in liver enzymes, biochemical parameters, anthropometric indices and any change in the level of physical activity. The reasons for noncompliance were also recorded. Data was analysed using SPSS 22. RESULTS: Out of 118 subjects enrolled, 61(51.69%) completed the study. Most patients were females 81(68.6%), married 25(21.2%) and housewives 64(54.2%). There were 16(26.2%) subjects who had 3-10kg weight reduction. The reduction in serum cholesterol and triglyceride levels was not significant (p>0.05). Also, no significant change was observed in the level of physical activity compared to the baseline (p>0.05). Overall, 27(44.3%) patients showed compliance with treatment. The main reasons for noncompliance were lack of time 21(34.4) and knee joint pain 5(8.2%). Conclusion: Lifestyle modification can be beneficial for weight-loss in the management of non-alcoholic fatty liver disease. However, awareness of its importance and willingness in initiating real-life practical steps with subsequent adherence to dietary therapy was found lacking in the sample studied.
