    Background: The global surge in obesity has reignited the need for larger cuff sizes to avoid inaccurate blood pressure (BP) readings and inappropriate antihypertensive treatment. More precise methods are essential. Forearm BP measurement has emerged as a promising alternative, showing strong correlation with noninvasive beat-to-beat monitoring. This study aimed to validate the digital oscillometric method on the forearm, comparing results to brachial artery readings in hypertensive patients with prediabetes and obesity. Methods: A non-randomized, open, cross-sectional observational study was conducted with 72 hypertensive individuals presenting with obesity and prediabetes. BP was measured using oscillometric devices on both the arm and forearm, following standardized protocols. Data were analyzed using Pearson correlation and Bland–Altman agreement tests. Results: Arm and forearm BP readings showed high agreement: r = 0.86 for systolic BP (SBP), r = 0.93 for diastolic BP (DBP), and r = 0.90 for mean arterial pressure (MAP). Bland–Altman analysis confirmed equivalence (SBP: p = 0.8, DBP: p = 0.3, MAP: p = 0.2). Conclusions: Forearm BP measurement is a reliable and effective alternative, particularly for hypertensive patients with prediabetes and obesity. It offers accurate readings, reduces treatment risks, and supports better clinical decisions. Broader studies are needed for generalization.

    Background Glucagon-like peptide 1 receptor agonists have been proven to be effective in adults with obesity. However, robust evidence on their effects on body weight, obesity-related metabolic changes, and safety in children and adolescents with obesity remains limited, making them a subpopulation with scant treatment options. Therefore, this meta-analysis aimed to determine more precise estimates of the efficacy and safety of glucagon-like peptide-1 agonists in pediatric obesity. Methods Three databases were searched (PubMed, Embase, and Cochrane Central Register of Controlled Trials) for trials published until the half of September 2024. The search indexing terms included 3 categories: [1] obesity [2], youth, and [3] glucagon-like peptide-1 receptor agonist (GLP-1 RA). Randomized controlled trials in youth with obesity (age ≤ 18 years) that assessed anthropometric and metabolic parameters were included. A total of 2016 studies were retrieved, and 24 full-text articles were screened. The data were analyzed using both mean differences (MDs) and standardized mean differences (SMDs) with 95% CIs and odds ratios (ORs) with 95% CIs. We applied a random effects model. Our outcomes were body weight (BW), BMI, waist circumference (WC), lipid profile, Hb1Ac, fasting blood glucose (FBG), blood pressure, and side effects. Results Eight studies comprised of 715 children and adolescents were included. On average, GLP-1 RA reduced BMI (SMD −0.67; 95% CI −0.8 to −0.41), BW (SMD −0.60; 95% CI −0.89 to −0.44), and WC (SMD −0.40; 95% CI −0.61 to −0.18). Although lipid profiles, HbA1c, and FBG were unaffected, GLP-1 RA was linked to a slight reduction in SBP (SMD −0.20; 95% CI −0.35 to −0.04) and an increase in HR (SMD + 0.26; 95% CI + 0.07 to +0.46), with no significant effect on DBP. Adverse effects, primarily nausea and vomiting, were more common in the intervention group, although trial withdrawal rates remained low. Conclusions Within this specific population, GLP-1 RAs exhibit significant reductions in BW, BMI, WC, and SBP. The analyses of lipid profiles, DBP, HbA1c, and FBG showed no significant changes. Also, the administration of these medications is concurrent with an elevated incidence of side effects, which are predominantly gastrointestinal and tolerable.

    The Possible Impact of COVID-19 on Glycated Hemoglobin and Systolic Blood Pressure in Type 2 Diabetes and Obesity

    by Tatiana Palotta Minari, Carolina Freitas Manzano, Louise Buonalumi Tácito Yugar, Luis Gustavo Sedenho-Prado, Tatiane de Azevedo Rubio, Lúcia Helena Bonalumi Tácito, Antônio Carlos Pires, José Fernando Vilela-Martin, Luciana Neves Cosenso-Martin, Nelson Dinamarco Ludovico, et al.

    Background: There are still discrepancies in the literature as to whether COVID-19 infection could impact biochemical, anthropometric, and cardiovascular markers. The purpose of this study was firstly to observe the effects of COVID-19 infection over 12 months on Type 2 diabetes (T2D) and obesity. Secondarily, we analyzed the individual influence of COVID-19 infection on changes in biochemical, anthropometric, and cardiovascular markers. Methods: This study is part of a secondary analysis of a recently published article. The research involved 84 participants with T2D, divided into two groups: the control group (40 participants) received only medical care, while the intervention group (44 participants) received both medical care and nutritional assessment. Consultations were held quarterly over 12 months, with a follow-up after 3 months. Data Analysis: For influence analysis, non-normal variables were compared using the Mann–Whitney test, and normal variables were compared using unpaired t-tests. For all cases, α = 0.05 and p < 0.05 were considered significant. Results: The analysis revealed a high percentage of patients in both groups who had a COVID-19 infection (70% control and 72.7% intervention) over 12 months. Regarding the influence analysis, participants in the intervention group who were infected with COVID-19 showed smaller reductions in glycated hemoglobin (HbA1c) (p = 0.0120) and systolic blood pressure (SBP) (p = 0.0460). For the other biochemical, anthropometric, and cardiovascular markers, in both groups, no significant differences were found (p > 0.05). Conclusion: COVID-19 possibly influenced SBP and HbA1c levels over 12 months in people with T2D and obesity. However, caution should be exercised in generalizing these results due to the limitations of this study. Additionally, influence analysis does not establish a causal relationship, and more clinical trials in different populations are needed to fully analyze this topic.

    The Impact of a Nutritional Intervention on Glycemic Control and Cardiovascular Risk Markers in Type 2 Diabetes

    by Tatiana Palotta Minari, Carolina Freitas Manzano, Lúcia Helena Bonalume Tácito, Louise Buonalumi Tácito Yugar, Luis Gustavo Sedenho-Prado, Tatiane de Azevedo Rubio, Antônio Carlos Pires, José Fernando Vilela-Martin, Luciana Neves Cosenso-Martin, Heitor Moreno, et al.

    Introduction: Nutritional management plays a crucial role in treating patients with type 2 diabetes (T2D), working to prevent and control the progression of chronic non-communicable diseases. Objectives: To evaluate the effects of individualized nutritional interventions on weight, body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), fasting blood glucose (FBG), hemoglobin A1c (HbA1c), total cholesterol (TC), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), triglycerides (TGs), systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR)} over 12 months and subsequently at follow-up (15 months). Methods: This longitudinal experimental study (without randomization and blinding) enrolled 84 sedentary participants with T2D (both sexes, aged 18–80 years). They were divided into a control group of 40 participants who received only medical consultations, and an intervention group of 44 participants who received the same medical care along with a nutritional assessment. Consultations occurred quarterly from August 2020 to November 2022 (first–twelfth month), with six to nine patients per session. Subsequently, a follow-up was conducted from December 2022 to November 2023, during which the intervention group had only medical care (during the 12th–15th months). Personalized dietary planning was inspired by the Mediterranean/DASH diets adapted to Brazilian foods and socioeconomic cultures. Statistical Analysis: Normal variables were compared between groups for each time point and also within each group across different time points using a two-way ANOVA (repeated measures for intragroup) followed by the Šídák post hoc test. Non-normal variables were compared between groups for each time point using Kruskal–Wallis followed by the Dunn post hoc test, and within each group across different time points using Friedman followed by the Dunn post hoc test. Data with a Gaussian distribution were presented as mean ± standard deviation (SD), and data with a non-Gaussian distribution were presented as median ± interquartile range (IQR). For all cases, α < 0.05 and p < 0.05 were adopted. Results: In the intervention group, significant reductions were observed between the first and twelfth month for all parameters (p < 0.05), (except for TC), along with an increase in HDL-C (p = 0.0105). Conversely, in the control group, there was a significant increase in HbA1c, weight, BMI, FBG, and WHR (p < 0.05) between the first and twelfth months. Regarding the comparison between groups, there was a significant difference for all analyzed parameters (p < 0.05) from the first to the twelfth month. In the follow-up, differences were also observed (p < 0.05), except for BMI (p > 0.05). Conclusion: The individualized nutritional intervention improved eating habits, anthropometric, biochemical, and cardiovascular markers in T2D over 12 months, with sustained results during follow-up. The dietary plan inspired by the Mediterranean and DASH diets demonstrated good adaptation to the Brazilian food culture and the patients’ socioeconomic contexts. Consistent monitoring and personalized nutritional management are essential for optimizing long-term outcomes. However, more clinical trials are necessary in order to optimize the level of evidence for longitudinal interventions.

    The efficacy and safety of GLP-1 receptor agonists in youth with type 2 diabetes: a meta-analysis

    by Louise Buonalumi Tacito Yugar, Luis Gustavo Sedenho-Prado, Isadora Maria Castilho da Silva Ferreira, Cleide Aparecida Moreira Silva, Andrei C. Sposito, Cintia Cercato

    Background: Glucagon-like peptide 1 receptor agonists have been proven to be effective in adults with diabetes and children with obesity. However, children with type 2 diabetes constitute an underrepresented subpopulation with limited treatment options. This meta-analysis aimed to determine more precise estimates of the efficacy and safety of glucagon-like peptide-1 agonists in pediatric type 2 diabetes mellitus. Methods: Three databases were searched (PubMed, Embase, and Cochrane Central Register of Controlled Trials) for trials published until the end of March 2024. The search indexing terms included 3 categories: [1] type 2 diabetes mellitus [2], youth, and [3] glucagon-like peptide-1 receptor agonist (GLP-1 RA). Randomized controlled trials in youth with type 2 diabetes (age ≤ 18 years) that assessed anthropometric and metabolic parameters were included. A total of 1119 nonduplicate studies were retrieved, and 137 full-text articles were screened. The data were analyzed using mean differences (MDs) with 95% CIs and odds ratios (ORs) with 95% CIs. For outcomes with low heterogeneity, a fixed-effects model was used. Otherwise, we applied a random effects model. Our outcomes were Hb1Ac, fasting blood glucose (FBG), blood pressure, weight, and side effects. Results: Five studies comprehending 415 children and adolescents were included. On average, GLP-1 RA reduced HbA1c levels (-1.01%; 95% CI, -1.26 to -0.76), fasting blood glucose levels (-1.88 mmol/L; 95% CI, -2.51 to -1.26), and body weight (-1.6 kg; 95% CI, -2.83 to -0.36). No significant reductions in systolic blood pressure (MD -0.19 mmHg; 95% CI, -3.9 to 3.52 mmHg) or diastolic blood pressure (MD 0.3 mmHg; 95% CI, -2.33 to 2.93 mmHg) were observed. Despite a higher incidence of side effects, withdrawal rates from the studies remained low. Conclusions: Within this specific population, GLP-1 RAs exhibit a notable association with substantial reductions in HbA1c, FBG, and body weight. The administration of these medications is concurrent with an elevated incidence of side effects, which are predominantly gastrointestinal and tolerable.

    Effects of Mindful Eating in Patients with Obesity and Binge Eating Disorder

    by Tatiana Palotta Minari, Gerardo Maria de Araújo-Filho, Lúcia Helena Bonalume Tácito, Louise Buonalumi Tácito Yugar, Tatiane de Azevedo Rubio, Antônio Carlos Pires, José Fernando Vilela-Martin, Luciana Neves Cosenso-Martin, André Fattori, Juan Carlos Yugar-Toledo, et al.

    Introduction: Binge eating disorder (BED) is a psychiatric illness related to a high frequency of episodes of binge eating, loss of control, body image dissatisfaction, and suffering caused by overeating. It is estimated that 30% of patients with BED are affected by obesity. “Mindful eating” (ME) is a promising new eating technique that can improve self-control and good food choices, helping to increase awareness about the triggers of binge eating episodes and intuitive eating training. Objectives: To analyze the impact of ME on episodes of binge eating, body image dissatisfaction, quality of life, eating habits, and anthropometric data [weight, Body Mass Index (BMI), and waist circumference] in patients with obesity and BED. Method: This quantitative, prospective, longitudinal, and experimental study recruited 82 patients diagnosed with obesity and BED. The intervention was divided into eight individual weekly meetings, guided by ME sessions, nutritional educational dynamics, cooking workshops, food sensory analyses, and applications of questionnaires [Body Shape Questionnaire (BSQ); Binge Eating Scale (BES); Quality of Life Scale (WHOQOL-BREF)]. There was no dietary prescription for calories, carbohydrates, proteins, fats, and fiber. Patients were only encouraged to consume fewer ultra-processed foods and more natural and minimally processed foods. The meetings occurred from October to November 2023. Statistical analysis: To carry out inferential statistics, the Shapiro–Wilk test was used to verify the normality of variable distribution. All variables were identified as non-normal distribution and were compared between the first and the eighth week using a two-tailed Wilcoxon test. Non-Gaussian data were represented by median ± interquartile range (IQR). Additionally, α < 0.05 and p < 0.05 were adopted. Results: Significant reductions were found from the first to the eighth week for weight, BMI, waist circumference, episodes of binge eating, BSQ scale score, BES score, and total energy value (all p < 0.0001). In contrast, there was a significant increase in the WHOQOL-BREF score and daily water intake (p < 0.0001). Conclusions: ME improved anthropometric data, episodes of binge eating, body image dissatisfaction, eating habits, and quality of life in participants with obesity and BED in the short-term. However, an extension of the project will be necessary to analyze the impact of the intervention in the long-term.

    Nutritional Strategies for the Management of Type 2 Diabetes Mellitus: A Narrative Review

    by Tatiana Palotta Minari, Lúcia Helena Bonalume Tácito, Louise Buonalumi Tácito Yugar, Sílvia Elaine Ferreira-Melo, Carolina Freitas Manzano, Antônio Carlos Pires, Heitor Moreno, José Fernando Vilela-Martin, Luciana Neves Cosenso-Martin, Juan Carlos Yugar-Toledo

    Background: Thinking about greater adherence to dietary planning, it is extremely important to be aware of all nutritional strategies and dietary prescriptions available in the literature, and of which of them is the most efficient for the management of T2DM. Methods: A search was carried out in 2023 for randomized clinical trials, systematic reviews, meta-analyses, and guidelines in the following databases: Pubmed, Scielo, Web of Science, CrossRef and Google Scholar. In total, 202 articles were collected and analyzed. The period of publications was 1983–2023. Results: There is still no consensus on what the best nutritional strategy or ideal dietary prescription is, and individuality is necessary. In any case, these references suggest that Mediterranean Diet may of greater interest for the management of T2DM, with the following recommended dietary prescription: 40–50% carbohydrates; 15–25% proteins; 25–35% fats (<7% saturated, 10% polyunsaturated, and 10% monounsaturated); at least 14 g of fiber for every 1000 kcal consumed; and <2300 mg sodium. Conclusions: Individuality is the gold standard for dietary prescriptions, however, the Mediterranean diet with low levels of carbohydrates and fats seems to be the most promising strategy for the management of T2DM.
