ABSTRACT Objective: To evaluate the predictive validity and cut-off point of heart rate and blood pressure on heart rate variability (HRV) changes in children with and without obesity. Methods: This study included 125 children, of whom 41 were normal weight and 84 were obese. Anthropometry, blood pressure, heart rate, and HRV were measured using an electronic scale and stadiometer, a sphygmomanometer, and HRV monitor. In addition, the receiver operating characteristic (ROC) curve was obtained by statistical analysis of the data. Results: Heart rate proved to be a good predictor for changes in the square root of the mean of the square of the differences between consecutive NN intervals (RMSSD) parameter in students of both sexes for the normal-weight group (ROC 0.89; 95%CI 0.77–1.00) and obesity (ROC 0.90; 95%CI 0.83–0.97). In addition, the heart rate cut-off point for alterations in the RMSSD parameter for normal-weight boys was 93 bpm (sensitivity 100.00% and specificity 87.50%) and for boys with obesity, the established cut-off point was 91 bpm (sensitivity 94.74% and specificity 63.64%). Heart rate also proved to be a good predictor considering low-frequency/high-frequency ratio (LF/HF) and standard deviation of long-term continuous NN intervals /standard deviation of the instantaneous variability of continuous NN intervals in the Poincaré graph ratio (SD2/SD1). Systolic and diastolic blood pressures were good predictors in more specific stratifications and, therefore, can be used in some cases. Conclusions: The predictive validity of heart rate was shown to be at a good level, with high sensitivity and acceptable specificity for the cut-off points according to the different analyses stratified by gender and nutritional status. In this sense, health professionals will be able to use heart rate to estimate cardiovascular risk in children of different sexes and nutritional status.

RESUMO Objetivo: Avaliar a validade preditiva e o ponto de corte da frequência cardíaca e da pressão arterial nas alterações da variabilidade da frequência cardíaca (VFC) em crianças com e sem obesidade. Métodos: Foram incluídas 125 crianças neste estudo, sendo 41 com peso normal e 84 com obesidade. Antropometria, pressão arterial, frequência cardíaca e VFC foram medidas por meio de balança eletrônica e estadiômetro, esfigmomanômetro e monitor de VFC. Além disso, a curva característica de operação do receptor (ROC) foi obtida pela análise estatística dos dados. Resultados: A frequência cardíaca mostrou-se um bom preditor de alterações no parâmetro de raiz quadrada da média do quadrado das diferenças entre os intervalos NN consecutivos (RMSSD) em escolares de ambos os sexos para o grupo de peso normal (ROC 0,89; IC95% 0,77–1,00) e obesidade (ROC 0,90; IC95% 0,83–0,97). Além disso, o ponto de corte da frequência cardíaca para alterações no parâmetro RMSSD para meninos com peso normal foi de 93 bpm (sensibilidade 100,00% e especificidade 87,50%), e para meninos com obesidade, o ponto de corte estabelecido foi de 91 bpm (sensibilidade 94,74% e especificidade 63,64%). A frequência cardíaca também se mostrou um bom preditor considerando os índices da relação baixa frequência/alta frequência (LF/HF) e razão desvio padrão de intervalos NN contínuos de longo prazo/desvio padrão da variabilidade instantânea de intervalos NN contínuos na relação gráfica de Poincaré (SD2/SD1). As pressões arteriais sistólicas e diastólicas foram bons preditores em estratificações mais específicas e, portanto, podem ser utilizadas em alguns casos. Conclusões: A validade preditiva da frequência cardíaca mostrou-se em bom nível, com alta sensibilidade e especificidade aceitável para os pontos de corte, conforme as diferentes análises estratificadas por sexo e estado nutricional. Desta forma, os profissionais de saúde poderão utilizar a frequência cardíaca para estimar o risco cardiovascular em crianças de diferentes sexos e estado nutricional.

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.

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.

Resumo Introdução: O objetivo deste estudo foi investigar o papel do fenofibrato, um agonista do receptor ativado por proliferadores de peroxissoma-α, na lesão renal induzida por obesidade (lipotoxicidade) em camundongos submetidos à uninefrectomia. Métodos: Camundongos C57BL/6 foram submetidos a uninefrectomia e cirurgias simuladas (sham) e alimentados com dietas normocalóricas ou rica em gordura. Após 10 semanas, os camundongos obesos receberam fenofibrato a 0,02% por 10 semanas. Avaliamos função e morfologia renal, bem como níveis de mediadores inflamatórios e fibróticos e marcadores do metabolismo lipídico. Resultados: Camundongos alimentados com dieta rica em gordura desenvolveram obesidade e hiperlipidemia características, com subsequente acúmulo de lipídios e danos renais, incluindo expansão mesangial, fibrose intersticial, inflamação e proteinúria. Essas alterações foram maiores em camundongos obesos uninefrectomizados do que em camundongos obesos sham. O tratamento com fenofibrato preveniu hiperlipidemia e lesões glomerulares, reduziu o acúmulo de lipídios, melhorou a disfunção renal e atenuou a inflamação e fibrose renal. Além disso, o tratamento com fenofibrato reduziu a expressão no tecido renal do inibidor do ativador do plasminogênio-1, da proteína quimiotática de monócitos-1 e a expressão local do fator de crescimento de fibroblastos-21. Conclusão: A ativação do receptor ativado por proliferadores de peroxissoma-α pelo fenofibrato, com subsequente lipólise, atenuou lesões glomerulares e tubulointersticiais induzidas por lipotoxicidade renal, protegendo, assim, os rins de camundongos uninefrectomizados contra lesões induzidas por obesidade. Os achados do estudo sugerem uma via na ação farmacológica do fenofibrato, fornecendo insights sobre os mecanismos envolvidos no dano renal causado pela obesidade em doadores renais.

Abstract Introduction: The objective of this study was to investigate the role of fenofibrate, a peroxisome proliferator-activated receptor-α agonist, in obesity-induced kidney damage (lipotoxicity) in mice with uninephrectomy. Methods: C57BL/6 mice underwent uninephrectomy and sham surgeries and were fed normocaloric or high-fat diets. After 10 weeks, obese mice were administered 0.02% fenofibrate for 10 weeks. Kidney function and morphology were evaluated, as well as levels of inflammatory and fibrotic mediators and lipid metabolism markers. Results: High-fat diet-fed mice developed characteristic obesity and hyperlipidemia, with subsequent renal lipid accumulation and damage, including mesangial expansion, interstitial fibrosis, inflammation, and proteinuria. These changes were greater in obese uninephrectomy mice than in obese sham mice. Fenofibrate treatment prevented hyperlipidemia and glomerular lesions, lowered lipid accumulation, ameliorated renal dysfunction, and attenuated inflammation and renal fibrosis. Furthermore, fenofibrate treatment downregulated renal tissue expression of plasminogen activator inhibitor-1, monocyte chemoattractant protein-1, and local expression of fibroblast growth factor-21. Conclusion: Peroxisome proliferator-activated receptor-α activation by fenofibrate, with subsequent lipolysis, attenuated glomerular and tubulointerstitial lesions induced by renal lipotoxicity, thus protecting the kidneys of uninephrectomy mice from obesity-induced lesions. The study findings suggest a pathway in the pharmacological action of fenofibrate, providing insight into the mechanisms involved in kidney damage caused by obesity in kidney donors.

Abstract This study examines conversations with X user positions in Mexico about ultra-processed foods, which have recently been linked to obesity. Posts from 2019 and 2020 were identified through hashtags on the topics of "labeling," "ultra-processed," and "junk food." We used a mixed approach to identify word patterns and develop an analysis based on social network theory. We found 211,585 tweets and 904,484 retweets from 90,828 and 321,637 accounts, respectively. There was an emphasis on conversations during the legislative process, especially the hashtag #etiquetadoclaroya. The most intense interactions occurred in discussions about new front-of-package warnings. The most influential profiles belonged to the media, academia, and civil society. The food industry's involvement was limited, so its role in the debate is inconclusive. This method can be used in other countries to monitor discussions on regulations and other policies.

Resumen Este estudio examina conversaciones con posturas de usuarios de X en México acerca de los productos comestibles ultraprocesados, recientemente asociados con obesidad. Se identificaron publicaciones en 2019 y 2020 a través de hashtags en temáticas denominadas "etiquetado", "ultraprocesados" y "comida chatarra". Se utiliza un enfoque mixto para identificar patrones de palabras y desarrollar un análisis basado en la teoría de redes sociales. Se encontraron 211,585 tweets y 904,484 retweets de 90,828 y 321,637 cuentas, respectivamente. Hubo un énfasis en las conversaciones durante procesos legislativos, destacando el hashtag #etiquetadoclaroya. Las interacciones más intensas ocurrieron en las discusiones sobre un nuevo etiquetado de advertencia. Los perfiles más influyentes pertenecían a medios de comunicación, academia y sociedad civil. La participación de la industria alimentaria fue limitada, por lo que su papel en el debate no es concluyente. Este método puede usarse en otros países para monitorear la discusión de regulaciones o políticas.

Resumo: Introdução : A obesidade está relacionada a um alto risco cardiovascular (RCV). Isso nos obriga a adotar comportamentos terapêuticos e preventivos. O objetivo deste trabalho é avaliar o risco cardiovascular em uma população com obesidade mórbida e avaliar a correta indicação de estatinas. Metodologia: Estudo transversal, descritivo, observacional, com a população com obesidade mórbida do Programa de Obesidade e Cirurgia Bariátrica (POCB) do Hospital Maciel, no período de novembro de 2014 a março de 2020. O RCV foi avaliado com a calculadora da organização pan-americana de saúde. A indicação de estatinas foi considerada de acordo com RCV ou diagnóstico de dislipidemia. Resultados: Foram analisados 478 pacientes, 84,3% eram mulheres, a mediana de idade foi de 44 anos e o IMC foi de 50 kg/m2. Um RCV baixo foi calculado para 57% dos pacientes; e alto ou muito alto para 37%. A prevalência de dislipidemia foi de 84,3%, com predomínio de hipercolesterolemia (33,7%) e dislipidemia aterogênica (19,5%). 60,6% (290) dos pacientes têm indicação de tratamento com estatinas, apenas 38,9%. (113) os recebe. 38,1% (43) alcançaram objetivos terapêuticos. Conclusões: A obesidade apresenta múltiplas comorbidades que aumentam o RCV, mas é subestimada pelas calculadoras de risco. É evidente o subtratamento farmacológico destes pacientes, não atingindo os objetivos terapêuticos propostos.

Abstract: 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.

Abstract GLP1 receptor agonists (GLP1-RAs) are drugs that mimic the effects of the incretin hormone GLP1 and were initially introduced in medicine for the treatment of diabetes in 2005 and for obesity in 2014. Over time, data from secondary and exploratory objectives of large randomized controlled-trials suggested that GLP1-RAs could also exert renal action by slowing the progression of kidney disease in patients with and without diabetes. Based on this rationale, the Flow study (1 mg semaglutide vs placebo) was designed and recruitment began in 2019 until May 2021. The recently published results confirmed the effect of semaglutide in reducing the composite renal outcome. However, similar to SGLT2 inhibitors, the potential mechanisms behind the renal effects of GLP1-RAs still need to be elucidated. The aim of this review is to address the different physiological mechanisms of GLP1-RAs at the renal level, using evidence from experimental studies and current scientific literature.

Resumo Os agonistas do receptor de GLP1 (GLP1-RAs) são medicamentos que imitam os efeitos do hormônio incretínico GLP1. Eles foram inicialmente introduzidos na medicina para o tratamento do diabetes em 2005 e para a obesidade em 2014. Com o passar do tempo, dados provenientes de objetivos secundários e exploratórios de amplos ensaios clínicos randomizados sugeriram que os GLP1-RAs também poderiam exercer ação renal ao retardar a progressão da doença renal em pacientes com e sem diabetes. Com base nesse raciocínio, o estudo Flow (semaglutida 1 mg vs. placebo) foi desenhado e o recrutamento começou em 2019, estendendo-se até maio de 2021. Os resultados publicados recentemente confirmaram o efeito da semaglutida na redução do desfecho renal composto. No entanto, assim como os inibidores do SGLT2, os mecanismos potenciais por trás dos efeitos renais dos GLP1-RAs ainda precisam ser elucidados. O objetivo desta revisão é abordar os diferentes mecanismos fisiológicos dos GLP1-RAs em nível renal, utilizando evidências de estudos experimentais e da literatura científica atual.

Obesity is recognized as a significant risk factor for various types of cancer. Although the incidence of some types of cancer of various primary sites is decreasing due to specific prevention measures (screening programs, smoking cessation), the incidence of neoplasms in the young population shows a significant increase associated with obesity. There is sufficient evidence to say that bariatric surgery has been shown to significantly lower the risk of developing obesity-associated cancers, which are linked to metabolic dysregulation, chronic low-grade systemic inflammation, and hormonal alterations such as elevated insulin and sex hormone levels.

A obesidade é reconhecida como um fator de risco significativo para vários tipos de câncer. Embora a incidência de alguns tipos de câncer de vários locais primários esteja diminuindo devido a medidas específicas de prevenção (programas de triagem, cessação do tabagismo), a incidência de neoplasias na população jovem mostra um aumento significativo associado à obesidade. Há evidências suficientes para dizer que a cirurgia bariátrica demonstrou reduzir significativamente o risco de desenvolver cânceres associados à obesidade, que estão ligados à desregulação metabólica, inflamação sistêmica crônica de baixo grau e alterações hormonais, como níveis elevados de insulina e hormônios sexuais.

SUMMARY: Sarcopenia is a disease characterized by a decline in skeletal muscle mass, strength, and physical performance, leading to a loss of functional capacity. Appendicular skeletal muscle mass (ASMM) is one of the most used measurements to detect skeletal muscle mass loss; nevertheless, its assessment is expensive. Under this context, indirect anthropometric measurements include calf circumference (CC) and appendicular skeletal muscle mass index (SMI). However, these measurements may not be very sensitive in older people with different body mass index (BMI). The aim of this study was to determine the influence of BMI on indirect measurements of ASMM in overweight and obese older people. This study included 57 participants aged 60 years and over from the city of Los Angeles, Chile, divided into two groups according to nutritional status, overweight (OW; n=33; Men=8; Women=25; age, 72 ± 6 years; BMI, 27.54 ± 1.54 kg·m-2) and obesity (OB; n=24; Men=5; Women=19; age, 72. ± 6 years; BMI, 33.70 ± 6.22 kg·m-2). The results showed that 36 % of the variations observed in CC measurements are explained by BMI (p<0.05). Conversely, the variations in SMI are not explained by BMI. In conclusion, BMI in older people can affect CC results, but not SMI. These results contribute to the decision-making process regarding the use of SMI as a better method for the indirect measurement of ASMM in overweight and/or obese older individuals.

RESUMEN: La sarcopenia es una enfermedad caracterizada por una disminución de la masa del músculo esquelético, la fuerza y el rendimiento físico, lo que conduce a una pérdida de la capacidad funcional. La masa de músculo esquelético apendicular (ASMM) es una de las mediciones más utilizadas para detectar la pérdida de masa de músculo esquelético; sin embargo, su evaluación es costosa. En este contexto, las mediciones antropométricas indirectas incluyen la circunferencia de la pantorrilla (CC) y el índice de masa del músculo esquelético apendicular (SMI). Sin embargo, estas mediciones pueden no ser muy sensibles en personas mayores con diferentes índices de masa corporal (IMC). El objetivo de este estudio fue determinar la influencia del IMC en las mediciones indirectas de ASMM en personas mayores con sobrepeso y obesidad. Este estudio incluyó a 57 participantes de 60 años y más de la ciudad de Los Ángeles, Chile, divididos en dos grupos según estado nutricional, sobrepeso (SP; n=33; Hombres=8; Mujeres=25; edad, 72 ± 6 años; IMC, 27,54 ± 1,54 kg·m-2) y obesidad (OB; n=24; Hombres=5; Mujeres=19; edad, 72 ± 6 años; IMC, 33,70 ± 6,22 kg·m-2). Los resultados mostraron que el 36 % de las variaciones observadas en las mediciones de CC son explicadas por el IMC (p<0,05). Por el contrario, las variaciones del SMI no se explican por el IMC. En conclusión, el IMC en personas mayores puede afectar los resultados del CC, pero no el SMI. Estos resultados contribuyen al proceso de toma de decisiones sobre el uso del SMI como un mejor método para la medición indirecta de ASMM en personas mayores con sobrepeso y/u obesidad.

SUMMARY OBJECTIVE: The aim of this study was to investigate the effect of different dietary inflammatory index diets on inflammatory markers, anthropometric measurements, and sleep quality in obese subjects. METHODS: This study was conducted in a public hospital in Turkey between November 2021 and May 2022. Participants with pro-inflammatory dietary habits were included in the study. Randomly divided into two groups of 33 participants, they were subjected to an anti-inflammatory diet or a control diet for 8 weeks. The study evaluated the anthropometric parameters, inflammatory biomarkers, and sleep quality indices of the diet groups. RESULTS: Significant reductions in body mass index were observed in both groups, more marked in the anti-inflammatory diet cohort. C-reactive protein levels, indicative of inflammation, also decreased substantially in both groups, with a more marked reduction in the anti-inflammatory diet cohort.

Abstract Objective To evaluate the association between inflammatory markers and abdominal fat assessed by ultrasound in prepubertal children with and without excess weight. Methods A cross-sectional study involving 241 prepubertal children, 156 with obesity, 37 with overweight, and 48 with normal weight, aged five to ten years, who were followed at a research unit on Childhood Obesity from a teaching hospital belonging to a public health system. The concentration of interleukin-6, tumor necrosis factor-α and C-reactive protein were assessed and regression analyses, considering outcome variables such as abdominal wall and intra-abdominal fat thickness measured by ultrasound, were performed. Results The findings highlighted an association between abdominal fat and inflammatory markers, even in children at this young age group. Subcutaneous fat showed a stronger association with inflammatory biomarkers compared to intra-abdominal fat when performing logistic regression, with a positive association between tumor necrosis factor-α and abdominal wall thickness equal to or greater than the 75th percentile in adjusted logistic regression (OR: 18.12; CI 95 %: 1.57: 209.55). Conclusions Abdominal wall fat, in contrast to what is often observed in adults, appears to have a greater impact on chronic inflammation related to excessive weight in very young children. crosssectional cross sectional 24 15 obesity 3 overweight 4 years system interleukin6, interleukin6 interleukin 6, 6 interleukin-6 factorα factor α Creactive C reactive analyses intraabdominal intra performed group th OR (OR 18.12 1812 18 12 9 % 1.57 157 1 57 209.55. 20955 209.55 . 209 55 209.55) adults 2 interleukin- 18.1 181 1.5 5 2095 209.5 20 18. 1. 209.

Abstract Introduction: Pre-eclampsia complicates 2-4% of pregnancies. Metformin is a promising therapeutic candidate as would reduce the secretion of soluble fms-like tyrosine kinase 1 and soluble endoglin from endothelial cells and primary villous trophoblasts. Objective: The objective of the study was to determine the effects and safety of metformin for preventing pre-eclampsia. Materials and methods: A systematic review was carried out with Cochrane methodology, performing an electronic search for randomized clinical trials in pregnant women, which compared the use of metformin with placebo or no intervention, and reported incidence of pre-eclampsia within their results. Review manager software was used for the statistical analysis. Results: Five studies were included with results for 1977 participants. A 56% reduction in the risk of pre-eclampsia in pregnant women who received metformin was found, compared to placebo or no intervention (RR 0.44; 95% confidence interval 0.21-0.90; random effects analysis; I2 = 71%; Tau2 = 0.46; low-quality evidence). No significant differences were found for the secondary outcomes. Conclusions: The use of metformin in overweight or obese pregnant women, beginning before 20 weeks of gestation, could reduce the risk of pre-eclampsia by 56%; however, the beneficial effect could be non-significant, due to heterogeneity and low quality of current evidence.

Resumen Introducción: La preeclampsia complica del 2 al 4% de los embarazos. La metformina es un candidato terapéutico prometedor, al reducir la secreción de tirosina-quinasa-1 soluble similar a fms (sFlt-1) y endoglina soluble (sEng) de las células endoteliales y los trofoblastos vellosos primarios. Objetivo: Se propone determinar los efectos y la seguridad de la metformina para prevenir la preeclampsia a través de una revisión sistemática con metodología Cochrane. Materiales y métodos: Se realizó búsqueda electrónica de ensayos clínicos aleatorizados en mujeres embarazadas, que compararon el uso de metformina con placebo o ninguna intervención, y reportaron dentro de sus resultados incidencia de preeclampsia. Resultados: Se incluyeron cinco estudios con resultados de 1977 participantes. Se encontró una reducción del 56% en el riesgo de preeclampsia en embarazadas que recibieron metformina, en comparación con placebo o ninguna intervención (RR 0,44; IC 95% 0,21-0,90; I2 = 71%; baja calidad evidencia). No hubo diferencias significativas para los resultados secundarios. Conclusiones: El uso de metformina en mujeres embarazadas con sobrepeso u obesidad, iniciado antes de las 20 semanas de gestación, podría reducir el riesgo de preeclampsia en un 56%. Sin embargo, el efecto beneficioso podría no ser significativo, dada la heterogeneidad y baja calidad de la evidencia actual.

Resumen Introducción. La hemocromatosis hereditaria es un trastorno metabólico hereditario común del metabolismo del hierro con penetrancia variable. La trombosis de la vena porta tiene varias causas bien conocidas que incluyen cirrosis, neoplasia mieloproliferativa, afecciones inflamatorias del abdomen, neoplasia maligna intraabdominal, cirugía intraabdominal y trombofilia. Se desconoce si la hemocromatosis hereditaria está asociada con la trombosis de la vena porta. Material y metodología. Se realizó un análisis retrospectivo de la base de datos de la Muestra Nacional de Pacientes Hospitalizados de 2016 a 2020 utilizando los códigos de la Clasificación Internacional de Enfermedades-10 para identificar hospitalizaciones con trombosis de la vena porta. Utilizamos un análisis de regresión multivariado para calcular el odds ratio ajustado después de controlar por edad, sexo, tipo de seguro, índice de comorbilidad de Charlson, cirrosis, neoplasia mieloproliferativa, afecciones inflamatorias del abdomen, neoplasia maligna intraabdominal, cirugía intraabdominal, antecedentes de trombosis pasada, trombofilia, enfermedad renal terminal, obesidad, tabaquismo e hiperlipidemia. Resultados . Hubo 25.805 hospitalizaciones con diagnóstico primario de trombosis de la vena porta. La regresión logística multivariada mostró que la hemocromatosis hereditaria se asoció de forma independiente con la trombosis de la vena porta (odds ratio = 4.7, IC del 95 % = 1.15 a 19.35, valor de p = 0,03) cuando se controlaron cirrosis, neoplasia mieloproliferativa, afecciones inflamatorias del abdomen, neoplasia maligna intraabdominal, antecedentes de trombosis, antecedentes de cirugía abdominal, antecedentes de trombofilia y enfermedad renal terminal, entre otros factores.

Abstract Introduction. Hereditary hemochromatosis is a common inherited metabolic disorder of iron metabolism with variable penetrance. Portal vein thrombosis has several well-known causes including cirrhosis, myeloproliferative neoplasm, inflammatory conditions of the abdomen, intra-abdominal malignancy, intra-abdominal surgery, and thrombophilia. It is unknown whether hereditary hemochromatosis is associated with portal vein thrombosis. Material and methodology. A retrospective analysis of the National Inpatient Sample database from 2016 to 2020 was conducted using International Classification of Diseases-10 codes to identify hospitalizations with portal vein thrombosis. We used multivariate regression analysis to calculate the adjusted odds ratio after controlling for age, gender, insurance type, Charlson Comorbidity Index, cirrhosis, myeloproliferative neoplasm, inflammatory conditions of the abdomen, intra-abdominal malignancy, intra-abdominal surgery, history of past thrombosis, thrombophilia, end-stage renal disease, obesity, smoking, and hyperlipidemia. Results. There were 25805 hospitalizations with primary diagnosis of portal vein thrombosis. Multivariate logistic regression showed that hereditary hemochromatosis was independently associated with portal vein thrombosis (Odds ratio= 4.7, 95% CI=1.15 to 19.35, p-value=0.03) when cirrhosis, myeloproliferative neoplasm, inflammatory conditions of the abdomen, intra-abdominal malignancy, history of thrombosis, history of abdominal surgery, history of thrombophilia, and end-stage renal disease among other factors were controlled.

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.

Resumen El síndrome metabólico (SM) se asocia con alteraciones metabólicas e inflamatorias que imprimen un mayor riesgo de desarrollar diabetes y enfermedades cardiovasculares y tiene como base la resistencia insulínica. La alimentación, sedentarismo, educación y distribución del ingreso pueden influir en la aparición del SM. El objetivo del estudio fue conocer la prevalencia del SM y los factores de riesgo cardiovascular asociados en una población vulnerable, adulta y urbana, que acudió voluntariamente luego de una campaña de difusión, a un hospital de atención primaria en la ciudad de San Luis, Argentina. En 451 sujetos, 205 hombres y 246 mujeres (45,5±12,4 años) se analizaron datos personales, antropométricos y biomarcadores: colesterol total, colesterol HDL (c-HDL), colesterol LDL, triglicéridos, glucosa, insulina, proteína C reactiva ultrasensible (PCRus), apolipoproteínas A y B, ácido úrico e índices subrogados de insulina. El SM se estableció empleando la definición armonizada de SM (2009). El 80% de la población no completó la educación formal. Los hombres estaban desempleados o con trabajo informal (70%). El 51,4% de la población cumplía con el criterio de SM (50,0% mujeres y 53,1% hombres). Entre los componentes del SM, la tríada más frecuente en mujeres y hombres, fue: c-HDL disminuido, circunferencia de cintura elevada e hipertrigliceridemia. El SM aumentó con la edad en los hombres. Las mujeres con SM presentaron niveles altos de PCRus. El conocimiento de la prevalencia local, tanto de la obesidad como del SM, permite valorar la magnitud del problema en cada comunidad, establecer medidas de prevención, control y compararlo con otras realidades epidemiológicas.

Resumo A síndrome metabólica (SM) está associada a alterações metabólicas e inflamatórias que aumentam o risco de desenvolvimento de diabetes e doenças cardiovasculares, considerando a resistência à insulina. A alimentação, o sedentarismo, a escolaridade e a distribuição de renda podem influenciar o aparecimento da SM. O objetivo do estudo foi conhecer a prevalência da SM e os fatores de risco cardiovascular associados em uma população vulnerável, adulta e urbana, que compareceu voluntariamente a um hospital de atenção primária na cidade de San Luis, Argentina, após uma campanha de divulgação. Em 451 indivíduos, 205 homens e 246 mulheres (45,5±12,4 anos), foram analisados dados pessoais, antropométricos e de biomarcadores: colesterol total, colesterol HDL (c-HDL), colesterol LDL, triglicerídeos, glicose, insulina, proteína C reativa ultrassensível (PCRus), apolipoproteínas A e B, ácido úrico e índices substitutos de insulina. A SM foi estabelecida utilizando a definição harmonizada de SM (2009). Oitenta por cento da população não concluiu a educação formal. Os homens estavam desempregados ou em trabalho informal (70%). 51,4% da população atendia os critérios da SM (50,0% mulheres e 53,1% homens). Dentre os componentes da SM, a tríade mais frequente em mulheres e homens: c-HDL diminuído, circunferência abdominal elevada e hipertrigliceridemia. SM aumentou com a idade nos homens. Mulheres com SM apresentaram níveis elevados de PCRus. O conhecimento da prevalência local da obesidade quanto da SM permite avaliar a magnitude do problema em cada comunidade, estabelecer medidas de prevenção e controle e compará-lo com outras realidades epidemiológicas.

Abstract Metabolic syndrome (MS) is associated with metabolic and inflammatory alterations that increase the risk of developing diabetes and cardiovascular diseases, based on insulin resistance. Diet, sedentary lifestyle, education and income distribution can influence the appearance of MS. The objective of the study was to know the prevalence of MS and associated cardiovascular risk factors in a vulnerable, adult and urban population, that voluntarily attends after diffusion campaign, to a primary care hospital in the city of San Luis, Argentina. In 451 subjects, 205 men and 246 women (45.5±12.4 years), personal, anthropometric and biomarker data were analysed: total cholesterol HDL cholesterol (HDL-c), LDL cholesterol, triglycerides, glucose, insulin, ultrasensitive C-reactive protein (usCRP), apolipoproteins A and B, uric acid and insulin surrogate indices. The MS was established using the harmonised definition of MS (2009). Eighty percent of the population did not complete formal education. Men were unemployed or in informal work (70%). A total of 51.4% of the population had the MS criteria (50.0% women and 53.1% men). Among the components of MS, the most frequent triad in women and men, were: decreased HDL-c, elevated waist circumference and hypertriglyceridemia. The prevalence of MS increased with age in men. Women with MS presented high levels of usCRP. Knowledge of the local prevalence of both obesity and MS would allow enable the assessment of the magnitude of the problem in each community, establish prevention and control measures, and compare it with other epidemiological realities.
