RESUMO
Introducción: La obesidad se relaciona con un riesgo cardiovascular (RCV) elevado. Esto nos obliga a tomar conductas terapéuticas y prevencionistas. El objetivo de este trabajo es evaluar el riesgo cardiovascular en una población de obesos mórbidos y valorar la correcta indicación de estatinas. Metodología: Estudio transversal, descriptivo, observacional, con la población obesos mórbidos del Programa de Obesidad y Cirugía Bariátrica (POCB) del Hospital Maciel, desde noviembre del 2014 a marzo del 2020. El RCV se valoró con la calculadora de la organización panamericana de la salud. La indicación de estatinas se consideró según RCV o diagnóstico de dislipemia. Resultados: Se analizaron 478 pacientes, el 84.3% fueron mujeres, la mediana para la edad fue de 44 años, y para el IMC 50 kg/m2. Se calculó un RCV bajo para el 57% de los pacientes; y alto o muy alto para un 37%. La prevalencia de las dislipemias fue 84,3%, a predominio de hipercolesterolemia (33,7%) y dislipemia aterogénica (19,5%). El 60.6% (290) de los pacientes presenta indicación de tratamiento con estatinas, solo el 38.9%. (113) las recibe. El 38.1% (43) alcanzan los objetivos terapéuticos. Conclusiones : La obesidad presenta múltiples comorbilidades que aumentan el RCV, aun así se encuentra subestimada por las calculadoras de riesgo. Queda en evidencia un infratratamiento farmacológico de estos pacientes, no logrando los objetivos terapéuticos propuestos.
Introduction: Obesity is related to a high cardiovascular risk (CVR). This forces us to take therapeutic and preventive behaviors. The objective of this work is to evaluate cardiovascular risk in a morbidly obese population and assess the correct indication of statins. Methodology: Cross-sectional, descriptive, observational study, with the morbidly obese population of the Obesity and Bariatric Surgery Program (POCB) of the Maciel Hospital, from November 2014 to March 2020. CVR was assessed with the calculator of the Pan-American health organization. The indication for statins was considered according to CVR or diagnosis of dyslipidemia. Results: 478 patients were analyzed, 84.3% were women, the median age was 44 years, and the BMI was 50 kg/m2. A low CVR was calculated for 57% of patients; and high or very high for 37%. The prevalence of dyslipidemia was 84.3%, with a predominance of hypercholesterolemia (33.7%) and atherogenic dyslipidemia (19.5%). 60.6% (290) of patients have an indication for treatment with statins, only 38.9%. (113) receives them. 38.1% (43) achieved therapeutic objectives. Conclusions: Obesity presents multiple comorbidities that increase CVR, yet it is underestimated by risk calculators. Pharmacological undertreatment of these patients is evident, not achieving the proposed therapeutic objectives.

RESUMO
Abstract Introduction: Living donor kidney transplantation is considered the ideal renal replacement therapy because it has a lower complication rate and allows an efficient response to the high demand for grafts in the healthcare system. Careful selection and adequate monitoring of donors is a key element in transplantation. Individuals at greater risk of developing kidney dysfunction after nephrectomy must be identified. Objective: To identify risk factors associated with a renal compensation rate (CR) below 70% 12 months after nephrectomy. Methods: This observational retrospective longitudinal study included living kidney donors followed up at the Lower Amazon Regional Hospital between 2016 and 2022. Data related to sociodemographic variables, comorbid conditions and kidney function parameters were collected. Results: The study enrolled 32 patients. Fourteen (43.75%) had a CR < 70% 12 months after kidney donation. Logistic regression found obesity (Odds Ratio [95%CI]: 10.6 [1.7-65.2]), albuminuria (Odds Ratio [95%CI]: 2.41 [1.2-4.84]) and proteinuria (Odds Ratio [95%CI]: 1.14 [1.03-1.25]) as risk factors. Glomerular filtration rate was a protective factor (Odds Ratio [95% CI]: 0.92 [0.85-0.99]). Conclusion: Obesity, albuminuria and proteinuria adversely affected short-term renal compensation rate. Further studies are needed to uncover the prognostic implications tied to these risk factors. Our findings also supported the need for careful individualized assessment of potential donors and closer monitoring of individuals at higher risk.
Resumo Introdução: O transplante de rim de doador vivo é considerado a terapia renal substitutiva ideal por oferecer menor taxa de complicações e possibilitar uma resposta eficiente à grande demanda por enxertos no sistema de saúde. A seleção criteriosa e o acompanhamento adequado dos doadores constituem um pilar fundamental dessa modalidade terapêutica, sendo essencial a identificação dos indivíduos em maior risco de disfunção renal pós-nefrectomia. Objetivo: Identificar fatores de risco para uma Taxa de Compensação (TC) da função renal inferior a 70% 12 meses após a nefrectomia. Métodos: Estudo observacional, retrospectivo e longitudinal conduzido com doadores de rim vivo acompanhados no Hospital Regional do Baixo Amazonas entre 2016 e 2022. Foram coletados dados correspondentes a variáveis sociodemográficas, comorbidades e parâmetros de função renal. Resultados: Foram incluídos 32 pacientes na amostra final. Destes, 14 (43,75%) obtiveram TC < 70% 12 meses após a doação. A regressão logística identificou a obesidade (Odds Ratio [IC95%]: 10.6 [1.7-65.2]), albuminúria (Odds Ratio [IC95%]: 2.41 [1.2-4.84]) e proteinúria (Odds Ratio [IC95%]: 1.14 [1.03-1.25]) como fatores de risco. A taxa de filtração glomerular atuou como fator de proteção (Odds Ratio [IC95%]: 0.92 [0.85-0.99]). Conclusão: Obesidade, albuminúria e proteinúria demonstraram impacto negativo na taxa de compensação renal em curto prazo, o que reitera a necessidade de estudos acerca das implicações prognósticas desses fatores. Além disso, reforça-se a necessidade de avaliação cuidadosa e individualizada dos possíveis doadores, com acompanhamento rigoroso, especialmente para indivíduos de maior risco.
RESUMO
RESUMEN Introducción: el índice de masa corporal y el perímetro abdominal son medidas antropométricas que podrían ser concordantes en la población peruana para el cribado de sobrepeso u obesidad. Objetivo: analizar la correlación y concordancia entre las pruebas de índice de masa corporal y perímetro abdominal para la detección de sobrepeso u obesidad en adultos peruanos. Metodología: estudio observacional, analítico y transversal basado en datos de la encuesta nacional demográfica de salud familiar. La población fue de 28960 adultos. Las variables fueron: índice de masa corporal y perímetro abdominal. Se utilizó la prueba V de Cramer, t de student, correlación de Spearman y kappa de Cohen. Resultados: hubo una asociación fuerte entre índice de masa corporal y perímetro abdominal en mujeres (V=0,701), moderada en hombres (V=0,632). En la prueba kappa de Cohen, ambas variables concordaron sustancialmente en mujeres (kappa=0,677) y moderadamente en hombres (kappa=0,580). Mediante el Odds Ratio, las mujeres con índice de masa corporal elevado tuvieron una probabilidad 97,22 veces mayor de perímetro abdominal elevado, mientras que en hombres con índice de masa corporal elevado fue 110,76 veces mayor. La correlación de Spearman fue muy alta y positiva en ambos sexos Conclusiones: el perímetro abdominal y el índice de masa corporal están asociados y correlacionados significativamente en adultos peruanos, presentaron una concordancia sustancial en mujeres y moderada en hombres. Se sugiere priorizar el uso del perímetro abdominal, debido a que distingue sobrepeso u obesidad según sexo, optimizándolo mediante la determinación de un punto de corte ajustado a la población peruana.
ABSTRACT Introduction: body mass index and abdominal perimeter are anthropometric measurements that could be concordant in the Peruvian population for screening for overweight or obesity. Objective: to analyze the correlation and agreement between body mass index and abdominal circumference tests for the detection of overweight or obesity in Peruvian adults. Methodology: observational, analytical and cross-sectional study based on data from the national demographic family health survey. The population was 28,960 adults. The variables were: body mass index and abdominal perimeter. Cramer's V test, student's t, Spearman's correlation and Cohen's kappa were used. Results: there was a strong association between body mass index and abdominal perimeter in women (V=0.701), moderate in men (V=0.632). In Cohen's kappa test, both variables agreed substantially in women (kappa=0.677) and moderately in men (kappa=0.580). Using the Odds Ratio, women with a high body mass index had a 97.22 times greater probability of having a high abdominal circumference, while in men with a high body mass index it was 110.76 times greater. The Spearman correlation was very high and positive in both sexes. Conclusions: abdominal circumference and body mass index are significantly associated and correlated in Peruvian adults; they presented substantial agreement in women and moderate agreement in men. It is suggested to prioritize the use of the abdominal perimeter, because it distinguishes overweight or obesity according to sex, optimizing it by determining a cut-off point adjusted to the Peruvian population.
RESUMO
BACKGROUND: This study evaluated the expression of ACE and ACE2 in the placenta and white adipose tissue in lean and obese women, and correlated their levels with anthropometric, clinical, and laboratory parameters, and tissue count of inflammatory cells. METHODS: A cross-sectional analytical study was performed with 49 pregnant women and their respective newborns. Samples of placenta and adipose tissue were used for measuring mRNA expression for ACE and ACE2 through qRT-PCR. Inflammatory cell counting was performed through conventional microscopy. RESULTS: An increase in ACE expression and a decrease in ACE2 were observed in the placenta and adipose tissue of women with obesity. ACE2 levels showed a negative correlation with pre-pregnancy BMI and total cholesterol. CONCLUSION: Maternal obesity can modulate the expression of RAS components in the placenta and white adipose tissue, with ACE2 correlated with pre-pregnancy BMI and total cholesterol.
RESUMO
Abstract Objective: To estimate the direct costs of treating excess body weight in children and adolescents attending a public children's hospital. Methods: This study analyzed the costs of the disease within the Brazilian Unified Health System (SUS) for 2,221 patients with excess body weight using a microcosting approach. The costs included operational expenses, consultations, and laboratory and imaging tests obtained from medical records for the period from 2009 to 2019. Healthcare expenses were obtained from the Table of Procedures, Medications, Orthoses/Prostheses, and Special Materials of SUS and from the hospital's finance department. Results: Medical consultations accounted for 50.6% (R$703,503.00) of the total cost (R $1,388,449.40) of treatment over the period investigated. The cost of treating excess body weight was 11.8 times higher for children aged 5-18 years compared to children aged 2-5 years over the same period. Additionally, the cost of treating obesity was approximately 4.0 and 6.3 times higher than the cost of treating overweight children aged 2-5 and 5-18 years, respectively. Conclusion: The average annual cost of treating excess body weight was R$138,845.00. Weight status and age influenced the cost of treating this disease, with higher costs being observed for individuals with obesity and children over 5 years of age. Additionally, the important deficit in reimbursement by SUS and the small number of other health professionals highlight the need for restructuring this treatment model to ensure its effectiveness, including a substantial increase in government investment.
RESUMO
ABSTRACT Purpose To evaluate the morphological and stereological parameters of the testicles in mice exposed to bisphenol S and/or high-fat diet-induced obesity. Material and Methods Forty adult male C57BL/6 mice were fed a standard diet (SC) or high-fat diet (HF) for a total of 12 weeks. The sample was randomly divided into 4 experimental groups with 10 mices as follows: a) SC - animals fed a standard diet; b) SC-B - animals fed a standard diet and administration of BPS (25 μg/kg of body mass/day) in drinking water; c) HF: animals fed a high-fat diet; d) HF-B - animals fed a high-fat diet and administration of BPS (25 μg/Kg of body mass/day) in drinking water. BPS administration lasted 12 weeks, following exposure to the SC and HF diets. BPS was diluted in absolute ethanol (0.1%) and added to drinking water (concentration of 25 μg/kg body weight/day). The animals were euthanized, and the testes were processed and stained with hematoxylin and eosin (H&E) for morphometric and stereological parameters, including density of seminiferous tubules per area, length density and total length of seminiferous tubules, height of the tunica albuginea and the diameter of the seminiferous tubules. The images were captured with an Olympus BX51 microscope and Olympus DP70 camera. The stereological analysis was done with the Image Pro and Image J programs. Means were statistically compared using ANOVA and the Holm-Sidak post-test (p<0.05). Results The seminiferous tubule density per area reduced in all groups when compared with SC samples (p<0.001): HF (40%), SC-B 3(2%), and HF-B (36%). Length density was reduced significantly (p<0.001) in all groups when compared with SC group: HF (40%), SC-B (32%), and HF-B (36%). The seminiferous tubule total length was reduced (p<0.001) when compared to f HF (28%) and SC-B (26%) groups. The tubule diameter increased significantly (p<0.001) only when we compared the SC group with SC (54%) an SC-B (25%) groups and the tunica thickness increased significantly only in HF group (117%) when compared with SC-B (20%) and HF-B 31%. Conclusion Animals exposed to bisphenol S and/or high-fat diet-induced obesity presented important structural alterations in testicular morphology.
RESUMO
Objetivo: A obesidade populacional afeta inúmeras nações do mundo, implicando custos econô¬micos, sociais e ambientais severos, comprometendo a condição de desenvolvimento sustentável. Este estudo tem como objetivo analisar a evolução da situação de sobrepeso e obesidade popu¬lacional dos países-membros da OCDE e do Brasil. Métodos: Este estudo analisa dados sobre a prevalência de sobrepeso e obesidade populacional disponibilizados pela OCDE para os seus paí¬ses-membros e pelo sistema Vigitel para o Brasil. Resultados: Os países da OCDE apresentam uma variabilidade grande na prevalência de sobrepeso/obesidade, e a prevalência média está na faixa dos 50%. Para o Brasil, a prevalência de sobrepeso e obesidade populacional aumentou expressiva¬mente nos últimos anos, indo de cerca de 45% em 2010 para 53,5% em 2020. Conclusão: A maioria dos países analisados está classificada em uma condição de taxa média de prevalência de sobrepeso e obesidade superior a 50% e uma tendência de crescimento dessa prevalência. O estudo ainda apresenta algumas ações e políticas públicas promovidas em outros países com o propósito de promover a redução da prevalência de sobrepeso e obesidade, e que poderiam ser adaptadas e implementadas no contexto brasileiro.
Objective: Population obesity affects many nations of the world, implying severe economic, social and environmental costs, compromising the condition of sustainable development. This study aims to analyze the evolution of the situation of overweight and obesity in the OECD member countries and Brazil. Methods: This study analyzes data on the prevalence of overweight and obesity made available by the OECD for its member countries, and by the Vigitel System for Brazil. Results: The OECD countries show a great variability in the prevalence of overweight/obesity, with the average prevalence being in the range of 50%. For Brazil, the prevalence of overweight and obesity in the population has increased significantly in recent years, going from about 45% in 2010 to 53.5% in 2020. Conclusion: Most of the countries analyzed are classified in a condition of average prevalence rate of overweight and obesity greater than 50% and a tendency for this prevalence to increase. The study also presents some actions and public policies promoted in other countries with the purpose of promoting the reduction of the prevalence of overweight and obesity, which could be adapted and implemented in the Brazilian context.
RESUMO
AIM: Tirzepatide (Tzp), a novel dual agonist glucose-dependent insulinotropic polypeptide/glucagon-like peptide-1, is approved for treating insulin resistance and obesity, and menopausal women consuming a high-calorie diet are a target to study the Tzp effect. Therefore, we aimed to allometrically scale body weight (BW) in Tzp-treated obese diabetic menopausal mice. MATERIALS AND METHODS: Three-month-old C57BL/6 female mice had bilateral ovariectomy (Ovx) or a sham procedure and for 12 weeks were fed a control diet or a high-fat and high sucrose diet (n = 120/each group [control (C), obese diabetic (Od), Ovx (O), sham (S), Tzp (T)]). Tzp was subcutaneously administered (10 nmol/kg) or vehicle once a day for an additional 4 weeks. The analysis considered log-transformed data and the allometric equation log y = log a + b log x. RESULTS: Od and OdO showed more upward slopes than C and CO. In C, BW was non-allometric by T administration. Od and OdO showed slightly positive slopes (more prominent in OdO than Od). OdT and OdOT showed negative slopes, significant intercepts, and more robust Pearson coefficients than untreated ones. A potent drug effect was seen with BW allometric decline. Interactions between diet versus Ovx and diet versus Tzp affected weight gain. Diet versus Ovx versus Tzp affected food intake. CONCLUSIONS: A model was developed to show three usual factors observed in mature women. Notably, Tzp improved the metabolism and weight loss of OdO mice. Tzp-treated mice showed negative allometric BW across treatment time, which is a quantitative assessment that allows better comparison between results.

BACKGROUND & AIMS: Asprosin is a promising candidate for novel treatments for metabolic-endocrine disorders. The objective of this systematic review and meta-analysis was to consolidate the existing evidence regarding asprosin levels in patients diagnosed with type 2 diabetes (T2D), metabolic syndrome (MetS), and obesity. METHODS: Scopus, Embase, PubMed, Ovid/Medline, and Web of Science were systematically searched without restrictions. We only used the standardized mean differences (SMD) with their 95 % confidence intervals (95 % CI) as the effect measure. A random-effects model (DerSimonian and Laird method) was used for the meta-analysis. Risk of bias was assessed with the Newcastle-Ottawa Scale and Newcastle-Ottawa Scale for Cross-Sectional Studies. RESULTS: Twenty-six studies (n = 3,787) were included in the meta-analysis. Participants with T2D had higher asprosin values than those without T2D (SMD: 1.64; 95 % CI: 1.08-2.21; I2 = 97 %). Patients with MetS had higher asprosin levels compared to those without MetS (SMD: 0.99; 95 % CI: 0.34-1.64; I2 = 96 %). Patients with obesity had higher asprosin levels than participants without obesity (SMD: 1.49; 95 % CI: 0.23-2.76; I2 = 98 %). CONCLUSIONS: Asprosin is significantly higher in patients with either T2D, MetS, or obesity, compared with controls.

PURPOSE: The relationship between dietary zinc (Zn) intake, metabolic diseases, and telomere length has been little explored in the children population. This observational cross-sectional study assesses the association between obesity (OB), cardiometabolic traits, telomere length, and dietary Zn intake in children with normal weight (NW) and OB from Mexico City. METHODS: Anthropometric data, blood pressure, biochemical measurements, the homeostatic model assessment of insulin resistance (HOMA-IR) and leucocyte telomere length (determined by quantitative-PCR) were analyzed in 171 children with NW and 172 with OB. Furthermore, dietary Zn intake was evaluated in 117 children NW and 120 with OB. RESULTS: Telomere shortening was associated with fasting plasma insulin (FPI) and HOMA-IR in NW (beta coefficient [ß]FPI = -0.022 ± 0.008, p = 0.009; ßHOMA-IR = -0.096 ± 0.040, p = 0.020) and OB (ßFPI = -0.007 ± 0.002, p = 0.003; ßHOMA-IR = -0.034 ± 0.012, p = 0.005) children. Dietary Zn intake resulted negatively associated with FPI (ß = -2.418 ± 0.764, p = 0.002) and HOMA-IR (ß = -0.399 ± 0.014, p = 0.009) in children with OB. Then, in children with OB, the association between FPI, HOMA-IR, and telomere shortening was evaluated separately in groups of low, medium, and high dietary Zn intake (according to tertiles). The association between FPI, HOMA-IR, and telomere shortening was not significant in the high Zn intake group (PFPI = 0.633; PHOMA-IR = 0.567). CONCLUSION: Our results suggest that a high Zn intake may ameliorate the telomere shortening related to high FPI and HOMA-IR.
RESUMO
Introduction: Genetic variants that control dopamine have been associated with obesity in children through loss of control of satiety and impulses, the manifestation of addictive eating behaviors, and specific personality traits. The variants include FTO-rs9939609 and the MAO-A 30 pb u-VNTR low-transcription alleles (LTA). Objective: To evaluate the genetic association of FTO-rs9939609 and the MAO-A LTA, along with personality traits and eating behavior with obesity in Mayan children from Mexico. Methods: We cross-sectionally evaluated 186 children (70 with obesity and 116 with normal weight) 6-12 years old from Yucatan, Mexico. Nutritional status was defined with body mass index (BMI) percentiles. Personality traits were evaluated with the Conners and TMCQ tests; eating behavior was evaluated with the CEBQ test. Genotyping with real-time PCR and TaqMan probes was used for FTO-rs9939609, whereas PCR amplification was used for MAO-A u-VNTR. Results: High-intensity pleasure (p = 0.013) and moderate appetite (p = 0.032) differed according to nutritional status. Heterozygous FTO-rs9939609 T/A children showed higher mean scores of low-intensity pleasure (p = 0.002) and moderate appetite (p = 0.027) than homozygous T/T. Hemizygous boys having MAO-A LTA showed significantly higher mean scores of anxiety (p = 0.001) and impulsivity (p = 0.008). In multivariate models, only LTA alleles of MAO-A explained obesity in boys (OR = 4.44; 95% CI = 1.18-16.63). Conclusion: In the present study, MAO-A u-VNTR alleles were associated with obesity in multivariate models only in boys. These alleles might also have a role in personality traits such as anxiety and impulsivity, which secondly contribute to developing obesity in Mayan boys.
RESUMO
BACKGROUND: The most frequent body composition alterations in post-COVID-19 syndrome include low muscle mass, dynapenia, sarcopenia, and obesity. These conditions share interconnected pathophysiological mechanisms that exacerbate each other. The relationship between body composition phenotypes and metabolic abnormalities in post-COVID-19 syndrome remains unclear. OBJECTIVE: To evaluate the association between body composition phenotypes and insulin resistance (IR) and metabolic abnormalities in non-diabetic individuals with post-COVID-19 syndrome. METHODS: A cross-sectional, single-center study involving 483 subjects with post-COVID-19 syndrome following moderate to severe acute COVID-19 requiring hospitalization. Individuals with diabetes, those who declined to participate, or those who could not be contacted were excluded. Body composition phenotypes were classified as normal weight, dynapenia, sarcopenia, dynapenic obesity, and sarcopenic obesity (SO). RESULTS: The average age was 52.69 ± 14.75 years; of note, 67.08% were male. The prevalence of body composition phenotypes was as follows: 13.25% were of normal weight, 9.52% had dynapenia, 9.94% had sarcopenia, 43.69% had obesity, 18.84% had dynapenic obesity, and 4.76% had SO. Additionally, 58.18% had IR. Obesity (OR: 2.98, CI95%; 1.64-5.41) and dynapenic obesity (OR: 4.98, CI95%; 1.46-6.88) were associated with IR. CONCLUSION: The most common body composition phenotypes were obesity, dynapenic obesity, and dynapenia. Furthermore, obesity and dynapenic obesity were associated with IR in post-COVID-19 syndrome.

The interaction between lifestyle--defined more specifically in health care as the personal exposome--and its implications on obesity and breast cancer development highlights the critical role of body composition and inflammation in these patients. There is clear evidence that the personal and internal exposome triggers biochemical, inflammatory, and metabolic reprogramming, which might favor ectopic lipid accumulation within the body, such as muscles. Additionally, the presence of excessive adipose tissue exacerbates these alterations in the internal exposome, resulting in cell damage and modifying body composition. Understanding the nexus between these lifestyle-induced exposome modifications, such as inflammation, and the resultant changes in body composition is crucial to assess the association with breast cancer progression and treatment responses. Various techniques can be used to evaluate body composition; one of those most used currently is bioelectrical impedance analysis. This analysis provides parameters, including phase angle (PhA), by which cellular health and metabolic activity can be assessed. In addition, PhA is a potential indicator of nutritional status and disease prognosis, as it has been linked to survival and quality of life in patients with cancer. Therefore, PhA might be used in daily oncology practice to implement an accurate nutritional intervention, reducing side effects and complications of oncology management, and improving quality of life during treatment and survival, even in patients with breast cancer with obesity or overweight. The aim of this review is to analyze the existing information on the current application of PhA in patients with breast cancer and its potential use as a tool to assess inflammatory response, identify malnutrition, and predict the deterioration of quality of life so that it could be proposed as an early indicator for nutritional interventions in this group of patients.

Studies have shown that deficiencies in magnesium, selenium, and zinc in individuals with obesity compromise the endogenous antioxidant defense system. This study aimed to evaluate the impact of mineral deficiency on enzymatic antioxidant defense in women with obesity. The study involved 63 women with obesity (BMI ≥ 35 kg/m2) and 77 eutrophic women (BMI between 18.5 and 24.9 kg/m2). Variables such as fasting glucose, glycated hemoglobin, fasting insulin, and serum lipids were analyzed. Insulin resistance was measured using the homeostasis assessment model (HOMA-IR) and beta cell function using the homeostasis assessment model (HOMA-ß). Dietary intake of energy, macronutrients (including magnesium, zinc, and selenium), and plasma, erythrocyte, and urinary concentrations of these minerals were measured and analyzed. Serum cortisol, plasma leptin, plasma thiobarbituric acid reactive substances, and the activity of erythrocyte superoxide dismutase (SOD), erythrocyte glutathione peroxidase (GPX), and erythrocyte catalase were also analyzed. Women with obesity had reduced plasma and erythrocyte concentrations and greater urinary excretion of all minerals compared to normal weight women (p < 0.05). There was a positive association between erythrocyte concentrations of zinc and selenium and the activity of the GPX and SOD enzymes in erythrocytes in women with obesity (p < 0.05), in addition to a positive association between serum insulin and the enzyme GPX, which is dependent on dietary selenium (p < 0.05). Individuals with obesity are deficient in magnesium, selenium, and zinc, which appears to impair the antioxidant defense system and contribute to important metabolic disorders such as oxidative stress in these patients.
RESUMO
The fruit of the cashew, a tree belonging to the family Anacardiaceae, is composed of approximately 10% nut (cashew) and 90% stalk or pseudofruit, usually discarded in situ and fermented in the soil. This review identifies cashew pseudofruit's physicochemical characteristics and bioactive compounds and their possible relationship to health benefits. Different processing techniques have been used to preserve the pseudofruit, and the effect of these techniques on its nutrients is also reviewed in this work. Cashew is a highly perishable product with moisture content above 80% w/w and 10% w/w sugars. It also has a high content of polyphenols, flavonoids, and tannins and high antioxidant properties that are best preserved by nonthermal processing techniques. The pseudofruit presents the high inhibitory activity of α-amylase and lipase enzymes, has anti-inflammatory and body weight reduction properties and healing activity, and controls glucose levels, insulinemia, and insulin resistance. For all these reasons, cashews have been promoted as a propitious food/ingredient for preventive and therapeutic management of different pathologies such as diabetes, dyslipidemia, obesity, hypertension, fatty liver, and acne. Moreover, it has positive effects on the intestinal microflora, among others. This pseudofruit has a high potential for the development of functional foods.

BACKGROUND: Despite evidence suggesting a relationship between religiosity and health habits, there is a paucity of studies specifically examining this association in the context of Peruvian university students. This study compared body mass index (BMI), adherence to a healthy lifestyle, and breakfast consumption in Peruvian university students of four religious denominations: Seventh Day Adventists (SDA), Catholics, Baptists, and Evangelicals. METHODS: A cross-sectional study was conducted online among 4557 students from a Peruvian university. The BMI and the frequency of breakfast consumption were evaluated, and the Diet and Healthy Lifestyle Scale (DEVS) was applied. The variables studied were associated using simple and multiple linear regression and Poisson models with robust variance. RESULTS: Baptist (B = 0.44, 95% CI: 0.10-0.78; p = 0.011), Catholic (B = 0.3, 95% CI: 0.12-0.47; p = 0.001), and Evangelical (B = 0.32, 95% CI: 0.09 to 0.64; p = 0.014) students had a significantly higher BMI compared to SDA. Baptist (B = -0.2, 95% CI: -0.37--0.05; p = 0.017) and Evangelical (B = -0.13, 95% CI: -0.28--0.03; p = 0.012) students exhibited a lower mean score on the measure of healthy lifestyles compared to SDA students. Additionally, Baptist (PR = -0.32, 95% CI: -0.92--0.12; p = 0.035) and Catholic (PR = -0.3, 95% CI: -0.99--0.19; p = 0.016) students exhibited a lower probability of eating breakfast regularly compared to SDA students. CONCLUSIONS: Health professionals should consider these findings when designing and implementing health promotion programs that are culturally sensitive and respectful of the beliefs and practices of all religious groups in university settings.

Both cardiometabolic and chronic inflammatory diseases pose a significant challenge to global public health, particularly among older adults. Here, we investigated the interplay between systemic inflammatory status and the cardiometabolic index (CMI) in older men with adequate weight or obesity. In this observational cross-sectional study, older men (71.79 ± 7.35 years) were separated into groups with normal weight (NW, n = 34) and obesity (O, n = 32) to assess circulating levels of pro- and anti-inflammatory cytokines and CMI. Overall, the O group showed not only a higher inflammatory status but also increased CMI (p < 0.0001) compared with the NW group. Interestingly, only positive correlations were found between pro- and anti-inflammatory cytokines in both groups. Through multivariate regression analysis, IL-6 (ß = -0.2276, p = 0.0003) and IL-10 (ß = 0.2023, p = 0.0030) significantly influenced CMI in the NW group. No significant results were found in the O group. Our findings reinforce the effects of obesity in inflammaging, as well as suggesting that the influence of cytokines in CMI occurs in older men with normal weight, since the elevated pro-inflammatory profile observed in older men with obesity can interfere in this effect.

In Mexico, 1 out of 3 schoolchildren aged 5 to 11 years is overweight or obese, which represents one of the main public health concerns, due to the fact that this condition in the child population is highly associated with the development of metabolic complications in adults. To date, dietary and physical activity interventions to prevent this problem have shown modest results worldwide. Biomedical studies in Mexico have shown that the pathophysiology of childhood overweight and obesity presents different molecular patterns, inflammation and oxidative stress, possibly associated with specific variants in the genome. However, the challenge is to achieve a secure characterization of this evidence so that it can be used in intervention studies aimed to improve the ability to predict and treat childhood overweight and obesity in Mexico. The biomedical challenge is to make knowledge a prevention strategy in families, in society and in the country, in order to fight the serious problem of obesity and its consequences.
En México 1 de cada 3 escolares de 5 a 11 años presenta sobrepeso u obesidad, lo cual representa una de las principales preocupaciones de salud pública, debido a que en la población infantil este padecimiento se asocia altamente con el desarrollo de complicaciones metabólicas en el adulto. Hasta el momento las intervenciones dietéticas y de actividad física para prevenir este problema han mostrado resultados modestos a nivel mundial. Los estudios biomédicos en México han demostrado que la fisiopatología del sobrepeso y la obesidad infantil presenta diferentes patrones moleculares, de inflamación y de estrés oxidativo, posiblemente asociados a variantes específicas en el genoma. Sin embargo, el reto es lograr la caracterización segura de estas evidencias para que sea posible emplearlas en los estudios de intervención encaminados a mejorar la capacidad de predicción y tratamiento del sobrepeso y la obesidad infantil en México. El reto biomédico es hacer del conocimiento una estrategia de prevención en las familias, en la sociedad y en el país, a fin de combatir el grave problema de la obesidad y sus consecuencias.

Background: Obesity creates a burden of disease that affects the health-related quality of life (HRQoL) of women and in those between 20 to 59 years of age it implies greater morbidity and mortality compared to men or other age groups. Objective: To evaluate the HRQoL of Mexican women aged 20 to 59 years with obesity. Material and methods: Observational, cross-sectional, prospective, and retrospective study. It was obtained a sample of 104 women from 20 to 59 years of age diagnosed with obesity according to the NOM-008-SSA3-2017 Standard. The participants' main clinical and sociodemographic characteristics were collected, and their HRQoL was evaluated with the SF-36 questionnaire. For the analysis of the collected variables, descriptive statistics were used. To identify the association of these variables with HRQoL, the Kruskal-Wallis test was used. Results: 104 women with a median age of 40.0 years participated. Of these, 66.3% had grade I obesity, 21.2% grade II, and 12.5% grade III. In the overall sample, general health and vitality were the lowest dimensions. In the comparison by groups, the physical role and the emotional role had statistically significant differences (p = 0.007 and p = 0.009, respectively), with the most affected group being obesity grade II. Conclusions: Obesity mainly affected the perception of general health and vitality; likewise, those with grade II had a greater impact on the physical role and the emotional role.
Introducción: la obesidad crea una carga de enfermedad que afecta la calidad de vida relacionada con la salud (CVRS) de las mujeres y en aquellas de 20 a 59 años implica una mayor morbilidad y mortalidad respecto a los hombres u otros grupos etarios. Objetivo: evaluar la CVRS de mujeres mexicanas de 20 a 59 años con obesidad. Material y métodos: estudio observacional, transversal, prospectivo y retrolectivo. Se obtuvo una muestra de 104 mujeres de 20 a 59 años, diagnosticadas con obesidad según la NOM-008-SSA3-2017. Se recabaron las principales características clínicas y sociodemográficas de las participantes y se evaluó su CVRS con el cuestionario SF-36. Para analizar las variables recogidas, se usó estadística descriptiva. Para identificar la asociación de estas variables con la CVRS, se usó la prueba Kruskal-Wallis. Resultados: participaron 104 mujeres con una mediana de edad de 40.0 años. De estas, 66.3% tuvieron obesidad grado I, 21.2% grado II y 12.5% grado III. En la muestra general, la salud general y la vitalidad fueron las dimensiones más bajas. En la comparación por grupos, el rol físico y el rol emocional tuvieron diferencias estadísticamente significativas (p = 0.007 y p = 0.009, respectivamente), y el grupo más afectado fue el de obesidad grado II. Conclusiones: la obesidad afectó principalmente la percepción de la salud general y de la vitalidad; asimismo, aquellas con grado II tuvieron una mayor repercusión en los roles físico y emocional.

Introduction: Globally, up to 76.6% of the population may be affected by vitamin D (VD) deficiency, which has been linked to increased morbidity and mortality from COVID-19. This underscores the importance of further research into VD supplementation, particularly for health care workers, who are at higher risk due to indoor work environments and dietary challenges associated with shift schedules. Objective: This study aimed to identify factors associated with VD deficiency in Mexican health care workers exposed to SARS-CoV-2. Materials and methods: We conducted a cross-sectional study from June 2020 to January 2021 among frontline health care workers treating hospitalized COVID-19 patients. Blood samples were collected to measure 25-hydroxy VD levels via radioimmunoassay. We also assessed previous COVID-19 infection and comorbidities that could influence VD levels. Results: The study included 468 health care workers. The median serum VD concentration was 16.6 ng/mL. VD deficiency was found in 69.4% (n = 325) of participants, while only 5.1% (n = 24) had normal levels. Those with type 2 diabetes (13.3 ng/mL vs. 17.1 ng/mL) or obesity (15.7 ng/mL vs. 17.1 ng/mL) had significantly lower VD levels than their counterparts (p < 0.001 and p = 0.049, respectively). No significant differences were found among participants with high blood pressure. Multivariate analysis revealed that type 2 diabetes was independently associated with VD deficiency. Conclusion: There is a high prevalence of VD deficiency among health care workers, which is potentially linked to both personal health factors and occupational conditions.
