Risk factors for lower renal compensation after nephrectomy: an analysis of living kidney donors in an Amazonian cohort / Fatores de risco para menor compensação renal pós-nefrectomia: análise de doadores de rim vivo em uma coorte amazônica

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.

Introducción. El sobrepeso y la obesidad infantil constituyen un problema de salud pública. El inicio de la pandemia por COVID-19 pudo haber favorecido esta patología. El puntaje Z del índice de masa corporal (Z-IMC) es un indicador aceptado para su diagnóstico y seguimiento. Objetivo. Evaluar si la prevalencia de sobrepeso y obesidad, y el Z-IMC en niños de 2 a 5 años aumentó durante la pandemia. Población y métodos. Estudio de cohorte retrospectiva. Se incluyeron pacientes asistidos en efectores públicos de salud del Gobierno de la Ciudad Autónoma de Buenos Aires (GCABA), de 2 a 5 años de edad, con registro de peso y talla en dos consultas, antes y después de haber comenzado el aislamiento social preventivo y obligatorio (ASPO). Se registró estado nutricional (Z-IMC) y variación del Z-IMC entre ambas consultas. Resultados. Se evaluaron 3866 sujetos, edad promedio 3,4 ± 0,8 años; el 48,1 % fueron mujeres. El intervalo promedio entre consultas fue 14,3 ± 2,5 meses. La prevalencia de sobrepeso/obesidad aumentó del 12,6 % (IC95% 11,6-13,6) al 20,9 % (IC95% 19,6-22-2); p <0,001, al igual que el Z-IMC (0,4 ± 1,1 vs. 0,8 ± 1,3; p <0,001). Conclusión. La prevalencia de sobrepeso y obesidad, y el Z-IMC en niños de 2 a 5 años aumentó significativamente durante la pandemia.

Introduction. Childhood overweight and obesity are a public health problem. The onset of the COVID-19 pandemic may have contributed to this condition. The body mass index (BMI) Z-score has been accepted as an indicator for overweight and obesity diagnosis and follow-up. Objective. To assess whether the prevalence of overweight and obesity and the BMI Z-score in children aged 2 to 5 years increased during the pandemic. Population and methods. Retrospective, cohort study. Patients included were those seen at public health care facilities in the City of Buenos Aires (CABA), who were aged 2 to 5 years, had weight and height values recorded at 2 different visits, before and after the establishment of the preventive and mandatory social isolation policy. Patients' nutritional status (BMI Z-score) and the variation in this indicator between both visits were recorded. Results. A total of 3866 subjects were assessed; their average age was 3.4 ± 0.8 years; 48.1% were girls. The average interval between both visits was 14.3 ± 2.5 months. The prevalence of overweight/ obesity increased from 12.6% (95% CI: 11.6­13.6) to 20.9% (95% CI: 19.6­22.2), p < 0.001, and so did the BMI Z-score (0.4 ± 1.1 versus 0.8 ± 1.3, p < 0.001). Conclusion. The prevalence of overweight and obesity and the BMI Z-score in children aged 2 to 5 years increased significantly during the pandemic.

Resultados cardiometabólicos de largo plazo tras cirugía bariátrica: control de comorbilidades, pérdida y reganancia de peso a los 5 años de seguimiento / Long-term cardiometabolic results after bariatric surgery: Control of comorbidities, weight loss and regain at 5 years of follow-up

Introducción. La cirugía bariátrica y metabólica (CBM) es efectiva en lograr pérdida de peso a corto plazo. Sin embargo, existe evidencia limitada en desenlaces clínicos y metabólicos a largo plazo. Métodos. Estudio longitudinal retrospectivo con pacientes llevados a baipás gástrico en Y de Roux (BGYR) o gastrectomía en manga (MG) por laparoscopia en Bogotá, D.C., Colombia, entre 2013 y 2021. El cambio de peso, control de comorbilidades y resultados metabólicos se recopilaron al inicio del estudio, 3, 6 y 12 meses después de cirugía, y anualmente hasta el quinto año. Las tasas de control de comorbilidades se evaluaron mediante la prueba Kaplan-Meier. Se utilizó un modelo de riesgos proporcionales de Cox para evaluar el efecto de covariables en la reganancia de peso. Resultados. De 1092 pacientes con CBM (71,4 % MG y 28,6 % BGYR), 67 % eran mujeres, con mediana de edad 48 años e índice de masa corporal de 35,5 Kg/m2. Después de cinco años de seguimiento, la tasa de control en diabetes mellitus fue 65,5 %, en hipertensión 56,6 % y en dislipidemia 43,6 %. La tasa de reganancia de peso fue 28 %, sin diferencias entre MG vs BGYR (p=0,482). El tiempo promedio hasta peso nadir fue 14 meses. La edad al momento de CBM fue el mejor predictor independiente de reganancia (HR=1,02, IC95% 1,01-1,04), pero con efecto clínico modesto. Conclusión. La CBM es segura y muestra beneficios a largo plazo en la pérdida de peso y control de comorbilidades en población colombiana.

Introduction. Bariatric and metabolic surgery (BMS) has shown its efficacy in achieving short-term weight loss. However, there is limited evidence regarding long-term clinical and metabolic outcomes. Methods. Retrospective longitudinal study with patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) interventions in Bogotá, Colombia, between 2013 and 2021. Weight change, comorbidity control, and metabolic outcomes were collected at the onset, 3-, 6-, and 12-month post-surgery, and annually up to the fifth year. Comorbidity control rates were assessed using the Kaplan-Meier test. A Cox proportional hazards model was used to evaluate the effect of covariates on weight regain. Results. Of 1092 patients with BMS (71.4% SG and 28.6% RYGB), 67% were women, with a median age of 48 years, BMI 35.5 kg/m2. After five years of follow-up, the control rate in diabetes mellitus was 65.5%, in hypertension 56.6%, and dyslipidemia 43.6%. The weight regain rate was 28% with no differences between SG vs RYGB (p=0.482). The mean time to nadir weight was 14 months. Age at the time of BMS was the best independent predictor of weight regain (HR=1.02, 95%CI: 1.01-1.04), but with a modest clinical effect. Conclusion. BMS is safe and shows long-term benefits in weight loss and control of comorbidities in Colombian population.

Evidencias del efecto del grano integral en las enfermedades crónicas no transmisibles

Los cereales integrales son una categoría de alimentos fundamental para la dieta humana y representan una fuente invaluable de carbohidratos, proteínas, fibras, fitoquímicos, minerales y vitaminas. Muchos estudios han demostrado que el consumo de cereales integrales está relacionado con un menor riesgo de enfermedades crónicas no transmisibles. Sin embargo, varios de sus efectos positivos para la salud parecen desaparecer cuando se refinan los cereales. La pregunta de investigación es cuál sería el efecto de los cereales integrales en la prevención de enfermedades crónicas no transmisibles. Este artículo describe los efectos positivos del consumo de cereales integrales en la prevención de estas enfermedades. Para ello, se realiza una descripción narrativa que revisa los antecedentes disponibles sobre: a) situación epidemiológica en Chile y su relación con la alimentación; b) consumo de cereales integrales en el mundo y en Chile; y c) el efecto del consumo de cereales integrales en la reducción del riesgo de enfermedad cardiovascular. obesidad, diabetes tipo 2 y cáncer. Los antecedentes generales son muy alentadores sobre el efecto positivo del consumo de cereales integrales sobre determinadas enfermedades, especialmente las de origen metabólico. Sin embargo, la incertidumbre de algunas asociaciones negativas merece mayor atención.

Whole grains are a fundamental food category for the human diet and represent an invaluable source of carbohydrates, proteins, fibers, phytochemicals, minerals and vitamins. Many studies have shown that consumption of whole grains is linked to a lower risk of chronic non-communicable diseases. However, several of its positive health effects seem to disappear when grains are refined. The research question is what would be the effect of whole grains in the prevention of Chronic Non-Communicable Diseases. This article describes the positive effects of whole grain consumption in these diseases.To this end, a narrative description is made that reviews the available background on: a) epidemiological situation in Chile and its relationship with diet; b) consumption of whole grains in the world and in Chile; and c) the effect of whole grain consumption on reducing the risk of cardiovascular disease. obesity, type 2 diabetes, and cancer. The general background is very encouraging for a positive effect of whole grain consumption on certain diseases, especially those of metabolic origin. However, the uncertainty of some negative associations deserves further attention.

Introducción Más de 600 mil personas en Chile viven con obesidad mórbida. La incorporación de intervenciones terapéuticas eficaces, seguras y costo-efectivas es crítica para los sistemas de salud y esquemas de aseguramiento. En el año 2022 se incorporaron al arancel de modalidad de libre elección del Fondo Nacional de Salud dos códigos de pago asociado a diagnóstico para cirugía bariátrica: gástrico y manga gástrica. El objetivo fue caracterizar la ejecución del programa de mecanismo de pago tipo pago asociado a diagnóstico de cirugía bariátrica en su primer año de implementación. Métodos Estudio descriptivo y observacional de abordaje pragmático de la ejecución nacional del pago asociado a diagnóstico en cirugía bariátrica. Se examinaron variables de caracterización sociodemográfica (sexo, tramos etarios y tramos del Fondo nacional de Salud) y caracterización de cirugías según código desagregadas por prestador público o privado, periodo de emisión, gasto unitario, copago, y préstamos médicos, entre marzo y diciembre de 2022. Resultados Se registraron n = 13 118 cirugías (45,81% versus 54,19% manga), de las cuales n = 2424 (18,48%) emplearon préstamos médicos. Un 85,01% (p = 0,01) de los procedimientos fueron en mujeres; en personas entre 35 y 39 años (20,15%); y 45,12% en beneficiarios del tramo B. El 99,21% de las cirugías se realizó en prestadores privados. Diez de estos concentraron el 50% de la actividad (rango n = 1200 a 426 cirugías anuales; n = 4,8 a 1,7 cirugías por día hábil). El gasto total del programa fue $71 626 948 350 CLP, explicando un 5,04% de la actividad total del Programa nacional de Pago Asociado a Diagnóstico. Conclusiones La implementación de este bono para cirugía bariátrica benefició a más de 13 mil personas que viven con obesidad, mayormente mujeres, en edades productivas, y con capacidad de compra. Como estrategia de equidad, independientemente de la vía de acceso mediante el bono, será importante cautelar la actividad en la red pública.

Introduction More than 600 thousand people in Chile live with morbid obesity. Effective, safe, cost-effective therapeutic interventions are critical for healthcare systems and insurance schemes. In 2022, two bundled payment codes for bariatric surgery (gastric bypass and gastric sleeve) were incorporated into the National Health Fund's free-choice modality fee scheme. The objective was to characterize the execution of this payment mechanism program associated with bariatric surgery diagnosis in its first year of implementation.More than six hundred thousand people in Chile are estimated to live with morbid obesity. Effective, safe, cost-effective therapeutic interventions are critical for health systems and insurance schemes. In 2022, FONASA incorporated two Bariatric Surgery codes into the Free Choice Modality: Gastric Bypass and Sleeve Gastrectomy. Our objective was to characterize the execution of the Bariatric Surgery Bundled Payment Program in its first year of implementation. Methods Descriptive and observational study of the pragmatic approach of the national execution of the payment associated with diagnosis in bariatric surgery. We examined sociodemographic variables (sex, age brackets, and National Health Fund tranches) and characterization of surgeries by code broken down by public or private provider, period of issue, unit cost, co-payment, and medical loans between March and December 2022. Results We recorded n = 13 118 surgeries (45.81% bypass versus 54.19% sleeve), of which n = 2424 (18.48%) used medical loans. A total of 85.01% (p = 0.01) of the procedures were in women, in people between 35 and 39 years of age (20.15%), and 45.12% in beneficiaries of tranche B. Private providers performed a total of 99.21% of the surgeries. Ten accounted for 50% of the activity (range n = 1200 to 426 surgeries per year; n = 4.8 to 1.7 surgeries per working day). Total program expenditure was $71 626 948 350 CLP, accounting for 5.04% of the total activity of the national Diagnosis Associated Payment Program. Conclusions The implementation of this bariatric surgery voucher benefited more than 13 thousand people living with obesity, mostly women of productive ages and with purchasing capacity. As an equity strategy, regardless of the access route through the voucher, it will be important to safeguard the activity in the public network.

Sonographic and Anatomical Evaluation of the Liver and Portal Vein Reference Values / Evaluación Ecográfica y Anatómica de los Valores de Referencia del Hígado y la Vena Porta

SUMMARY: This paper's aim is a morphometric evaluation of liver and portal vein morphometry using ultrasonography in healthy Turkish population. This study was carried out with 189 subjects (107 females, 82 males). The demographic data and the body surface area were calculated. The longitudinal axis of the liver for two lobes, diagonal axis or liver span, anteroposterior diameter of the liver and portal vein, portal vein transverse diameter, caudate lobe anteroposterior diameter, and portal vein internal diameters as well as longitudinal liver scans in an aortic plane, sagittal plane, transverse plane, and kidney axis were measured. All measurements were analyzed according to age, sex, body mass index, obesity and alcohol consumption. The mean values of the age, height, weight and body mass index were calculated as 44.39 years, 167.05 cm, 74.23 kg, and 27.06kg/m2 in females, respectively. The same values were 44.13 years, 167.70 cm, 75.93 kg and 26.71 kg/m2 in males, respectively. There was significant difference between demographic characteristics, gender, and alcohol consumption in terms of anteroposterior diameter of the liver, portal vein transverse diameter of the right side and liver transverse scan. Also, some measurements including portal vein transverse diameter, liver transverse scan and at kidney axis longitudinal scan of liver showed significant difference between the age groups. There was significant difference in diagonal axis and anteroposterior diameter of liver, portal vein internal diameter, and longitudinal liver scans of the aortic plane parameters between obesity situation. The findings obtained will provide important and useful reference values as it may determine some abnormalities related liver diseases. Also, age, sex, obesity and body mass index values can be effective in the liver and portal vein morphometry related parameters.

El objetivo de este artículo fue realizar una evaluación de la morfometría del hígado y la vena porta mediante ecografía en una población turca sana. Este estudio se llevó a cabo en 189 sujetos (107 mujeres, 82 hombres). Se calcularon los datos demográficos y la superficie corporal. Se midió eleje longitudinal del de dos lóbulos del hígado, el eje diagonal o la extensión del hígado, los diámetros anteroposterior del hígado y de la vena porta, el diámetro transversal de la vena porta, anteroposterior del lóbulo caudado y los diámetros internos de la vena porta, así como las exploraciones longitudinales del hígado en un plano aórtico. Se midieron el plano sagital, el plano transversal y el eje del riñón. Todas las mediciones se analizaron según edad, sexo, índice de masa corporal, obesidad y consumo de alcohol. Los valores medios de edad, talla, peso e índice de masa corporal se calcularon como 44,39 años, 167,05 cm, 74,23 kg y 27,06 kg/m2 en las mujeres, respectivamente. Las mismas variable fueron 44,13 años, 167,70 cm, 75,93 kg y 26,71 kg/m2. Hubo diferencias significativas entre las características demográficas, el sexo y el consumo de alcohol en términos de diámetro anteroposterior del hígado, diámetro transversal de la vena porta del lado derecho y exploración transversal del hígado. Además, algunas mediciones, incluido el diámetro transversal de la vena porta, la exploración transversal del hígado y la exploración longitudinal del hígado en el eje del riñón, mostraron diferencias significativas entre los grupos de edad. Hubo diferencias significativas en el eje diagonal y el diámetro anteroposterior del hígado, el diámetro interno de la vena porta y los parámetros de las exploraciones hepáticas longitudinales del plano aórtico entre situaciones de obesidad. Los hallazgos obtenidos proporcionarán valores de referencia importantes y útiles ya que pueden determinar algunas anomalías relacionadas con enfermedades hepáticas. Además, los valores de edad, sexo, obesidad e índice de masa corporal pueden ser eficaces en los parámetros relacionados con la morfometría del hígado y la vena porta.

Caracterización clínico-epidemiológica de pacientes con enfermedad hepática esteatósica asociada a disfunción metabólica previa al trasplante en un hospital de cuarto nivel / Clinical-epidemiological characterization of patients with steatotic liver disease associated with metabolic dysfunction prior to transplantation in a fourth level hospital

Introducción. La enfermedad hepática esteatósica asociada a disfunción metabólica (MASLD) se ha convertido en la enfermedad hepática crónica más frecuente en los países occidentales, causando un aumento en los costos y en la ocupación hospitalaria. La caracterización integral previa al trasplante hepático en pacientes con MASLD es una gran interrogante, especialmente en nuestro medio. El objetivo del presente estudio fue realizar la caracterización clínico-epidemiológica de pacientes trasplantados por cirrosis hepática (CH) descompensada o carcinoma hepatocelular (CHC) asociado a MASLD. Metodología. Se desarrolló un estudio observacional retrospectivo, descriptivo, de corte transversal en el Servicio de Hepatología del Hospital Pablo Tobón Uribe en Medellín, Colombia. Se incluyeron pacientes mayores de 17 años, con diagnóstico de CH o de CHC asociado a MASLD que fueron trasplantados entre los años 2004 a 2017. Resultados. Se encontraron 84 pacientes que fueron trasplantados con esas características. La edad promedio de los pacientes fue de 59±10,5 con una mayor proporción significativa de hombres sobre mujeres, llegando casi al 70 %. Con relación a las comorbilidades, se encontró que el sobrepeso/obesidad, la hipertensión arterial y la diabetes mellitus tipo 2 fueron un hallazgo en el 44,1 %, 33,3 % y 33,3 %, respectivamente. Por otro lado, el 14,5 %, el 33,7 % y el 51,8 % presentaron un Child-Pugh A, B y C, respectivamente. La media del puntaje MELD fue de 18,9±6,26. Con respecto a las complicaciones de la cirrosis, el 77,4 % de los pacientes presentó ascitis, el 61,9 % encefalopatía hepática, el 36,9 % hemorragia del tracto digestivo superior y el 29,8 % peritonitis bacteriana espontánea. Conclusión. Los resultados expuestos mostraron nuestra experiencia en trasplante hepático en pacientes con CH y CHC asociado a MASLD. Se debe realizar una evaluación multidisciplinaria antes y después del trasplante en estos pacientes, haciendo especial énfasis en el manejo de la disfunción metabólica y sus componentes, entre los que se destacan la obesidad y la diabetes mellitus.

The comprehensive pre-transplant characterization in patients with MASLD is a major question, especially in our setting. The aim of the present study was to perform the clinical-epidemiological characterization of transplanted patients with decompensated liver cirrhosis (LC) or hepatocellular carcinoma (HCC) associated with MASLD. Methodology. A retrospective, descriptive, cross-sectional observational study was carried out in the Hepatology Department of the Pablo Tobón Uribe Hospital in Medellin, Colombia. Patients over 17 years of age, with a diagnosis of LC or HCC associated with MASLD who were transplanted between 2004 and 2017 were included. Results. We found 84 patients who were transplanted with these characteristics. The mean age of the patients was 59±10.5 with a significantly higher proportion of men over women, reaching almost 70%. Regarding comorbidities, overweight/obesity, arterial hypertension, and type 2 diabetes mellitus were found in 44.1%, 33.3%, and 33.3%, respectively. On the other hand, 14.5%, 33.7%, and 51.8% had Child-Pugh A, B, and C, respectively. The mean MELD score was 18.9±6.26. Regarding complications of cirrhosis, 77.4% of patients developed ascites, 61.9% hepatic encephalopathy, 36.9% upper gastrointestinal tract hemorrhage, and 29.8% spontaneous bacterial peritonitis. Conclusion. The above results showed our experience of liver transplantation in patients with LC and HCC associated with MASLD. A multidisciplinary evaluation should be performed before and after transplantation in these patients, with special emphasis on the management of metabolic dysfunction and its components, including obesity and diabetes mellitus.

Impact of pre-operative weight loss on non-alcoholic fatty liver disease histopathology and insulin resistance in individuals undergoing bariatric surgery: a propensity matched cross-sectional comparison

ABSTRACT BACKGROUND: The effect of weight loss (WL) on histopathological aspects of non-alcoholic fatty liver disease (NAFLD) may provide further insights into the dynamics of hepatic recovery after WL. OBJECTIVE: To analyze the effects of pre-operative WL on insulin resistance- and NAFLD-related histology in individuals undergoing bariatric surgery (BS) with or without pre-operative WL. DESIGN AND SETTING: A matched cross-sectional study was conducted at a public university hospital and a private clinic in Campinas, Brazil. METHODS: An analytical, observational, cross-sectional study was conducted using prospectively collected databases of individuals who underwent BS and liver biopsy at either a public tertiary university hospital (with pre-operative WL) or a private clinic (without pre-operative WL). Random electronic matching by gender, age, and body mass index (BMI) was performed and two paired groups of 24 individuals each were selected. RESULTS: Of the 48 participants, 75% were female. The mean age was 37.4 ± 9.6. The mean BMI was 38.9 ± 2.6 kg/m2. Fibrosis was the most common histopathological abnormality (91.7%). Glucose was significantly lower in the WL group (92 ± 19.1 versus 111.8 ± 35.4 mg/dL; P = 0.02). Significantly lower frequencies of macrovesicular steatosis (58.3% versus 95.8%; P = 0.004), microvesicular steatosis (12.5% versus 87.5%; P < 0.001), and portal inflammation (50% versus 87.5%; P = 0.011) were observed in the WL group. CONCLUSION: Pre-operative WL was significantly associated with lower frequencies of macro- and mi- crovesicular steatosis, portal inflammation, and lower glycemia, indicating an association between the recent trajectory of body weight and histological aspects of NAFLD.

A systemic review on association between on maternal atmospheric pollution exposure during pregnancy and childhood obesity / 环境与职业医学

Background Maternal atmospheric pollution during pregnancy may alter fetal intrauterine development programming, thereby increasing the risk of childhood obesity in the future. Objective To investigate the effects of atmospheric pollution exposure during pregnancy on the incidence of childhood obesity in offspring. Methods English databases (PubMed, Web of Science, and Medline) and Chinese databases (Wanfang Data Knowledge Service Platform, China National Knowledge Infrastructure, and VIP Information Chinese Journal Service Platform) were searched for literature reporting exposure to atmospheric pollution during pregnancy and childhood obesity published from 1 January 2000 to 31 August 2023. The quality of the included literature was evaluated using the quality assessment tools for observational cohort and cross-sectional studies recommended by the US National Institutes of Health. Results Twenty-four studies meeting the inclusion criteria were identified and the associated atmospheric pollutants included particulate matter, ozone, nitrogen oxide, carbon oxide, and sulfur oxide. In comparison to the non-exposed group, prenatal exposure to various common atmospheric pollutants were significantly associated with an elevated risk of childhood obesity in offspring. Conclusion Maternal exposure to atmospheric pollution during pregnancy is associated with an elevated risk of childhood obesity in subsequent years. Future studies should pay more attention to the effects of atmospheric pollution on the distribution of children's body fat and metabolic development, and further identify potential mechanisms of atmospheric pollutant exposure leading to childhood obesity.

Influence factors of bone mineral density and its correlation with insulin resistance in obese children in Qianjiang area / 公共卫生与预防医学

Objective To explore the influencing factors of bone mineral density (BMD) in obese children in Qianjiang area and analyze the correlation between BMD and insulin resistance. Methods The data on pediatric cases from the outpatient department of Jianghan Oilfield General Hospital in Qianjiang from January 2018 to December 2022 were collected. A total of 183 obese children who met the inclusion and exclusion criteria were included in the study and selected in the observation group. A total of 352 children undergoing physical examination during the same period were selected as the control group. Results The body mass, waist circumference, waist to hip ratio, and BMI of obese children were significantly higher than those of the control group (P<0.001). Biochemical indexes including FBG, FINS, Home-IR, ALP, and LDL-C in obese children were significantly higher than those in the control group (P<0.05), while bone mineral density, Ca, P, sOC and HDL-C were significantly lower than those in the control group (P<0.001). The bone mineral density of obese children was significantly correlated with their exercise intensity, sunshine exposure duration, sitting time, intake of milk and dairy products, intake of sweets, supplementation of trace elements, BMI, Home-IR, and sex (all P<0.05). BMI, Home-IR, sex, exercise intensity, and sunshine exposure length were independent risk factors affecting bone mineral density of obese children (all P<0.05). Bone mineral density was negatively correlated with BMI and Home-IR (P=0.028 and0.017, respectively), and positive correlation with exercise intensity and sunlight exposure (P=0.033). Conclusion BMD of obese children in Qianjiang area is affected by gender, body mass index, diet, vitamin intake, and physical activity, and is negatively correlated with insulin resistance. Home-IR can be used as a reference for screening BMD of obese children.

ObjectiveTo observe and compare the intervention effect of modified Cangfu Daotantang on glucose and lipid metabolism in simple obese children with phlegm dampness and stagnation. MethodA total of 60 children with simple obesity were randomly divided into two groups according to the simple randomization method of the random number table. The odd number was included in the test group， and the even number was included in the basic treatment group， with 30 cases in each group. On the basis of signing the informed consent notice， the treatment group was given modified Cangfu Daotantang combined with basic treatment， while the control group was only given basic treatment. After three months of treatment， the body mass index （BMI）， glucose and lipid metabolism level ［total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， fasting plasma glucose （FPG）， fasting insulin （FINS）， and homeostasis model assessment-insulin resistance （HOMA-IR）］， the change in the total score of traditional Chinese medicine （TCM） syndromes， and the effective rate of treatment were observed and compared. ResultAfter treatment， the BMI of the observation group and the control group decreased significantly （P<0.01）. Compared with the control group， the BMI level in the observation group decreased significantly （P<0.05）. After treatment， the levels of TC， TG， and LDL-C in the observation group and the control group decreased significantly （P<0.01）. Compared with the control group， the levels of TC， TG， and LDL-C in the observation group decreased significantly （P<0.05）. In addition， the level of TC in the observation group improved significantly compared with that in the control group （P<0.01）. The levels of FPG， FINS， and HOMA-IR in the observation group and the control group were significantly lower than those before treatment （P<0.05）. After treatment， compared with the control group， the levels of FPG， FINS， and HOMA-IR in the observation group were significantly reduced （P<0.05）. The level of FPG in the observation group was significantly improved compared with that in the control group （P<0.01）. After treatment， the total score of TCM syndromes in the two groups decreased significantly （P<0.01）. Compared with the control group， the total score of TCM syndromes in the observation group was lower （P<0.01）. After treatment， the total effective rate of treatment was 86.67% （26/30） in the observation group and 73.33% （22/30） in the control group. By rank sum test， the total effective rate of the observation group was better than that of the control group （Z=-2.100， P<0.05）. ConclusionModified Cangfu Daotantang combined with basic treatment can effectively reduce the BMI of obese children and improve their glucose and lipid metabolism. It has good clinical effects and high clinical application value， which is worth further in-depth research and promotion.

Effect and Mechanism of Total Saponins from Panax Japonicus on White Adipose Tissue Browning/Brown Adipose Tissue Activation in High-fat Diet-induced Mice / 中国实验方剂学杂志

ObjectiveTo investigate the effect and mechanism of total saponins from Panax japonicus （TSPJ） on white adipose tissue （WAT） browning/brown adipose tissue （BAT） activation in C57BL6/J male mice fed on a high-fat diet （HFD）. MethodThirty-two C57BL6/J male mice （8-week-old） were randomly divided into a normal group， a model group， a low-dose TSPJ group， and a high-dose TSPJ group. The mice in the low-dose and high-dose TSPJ groups were given TSPJ for four months by gavage at 25， 75 mg·kg-1·d-1， respectively， and those in the other groups were given 0.5% sodium carboxymethyl cellulose （CMC-Na） accordingly. After four months of feeding， all mice were placed at 4 ℃ for acute cold exposure， and the core body temperature was monitored. Subsequently， all mice were sacrificed， and BAT and inguinal WAT （iWAT） were separated rapidly to detect the corresponding indexes. Hematoxylin-eosin （HE） staining was used to observe the morphological changes in each group. The effect of TSPJ on the mRNA expression of uncoupling protein 1 （UCP1）， fatty acid-binding protein 4 （FABP4）， cytochrome C （CytC）， PR domain-containing protein 16 （PRDM16）， elongation of very long chain fatty acids protein 3 （ELOVL3）， peroxisome proliferator-activated receptor γ （PPARγ）， and peroxisome proliferator-activated receptor-γ coactivator-1α （PGC-1α） in iWAT and BAT was detected by Real-time polymerase chain reaction （Real-time PCR）. Western blot was also used to detect the protein expression of UCP1， PRDM16， PPARγ， and PGC-1α in BAT and iWAT of each group. The effect of TSPJ on UCP1 expression in BAT and iWAT was detected by immunohistochemistry. Result① Compared with the model group， TSPJ could decrease the body weight and proportions of iWAT and BAT in the HFD-induced mice （P<0.05， P<0.01）. ② The body temperature of mice in the model group decreased compared with that in the normal group in the acute cold exposure tolerance test （P<0.05）. The body temperature in the high-dose TSPJ group increased compared with that in the model group （P<0.01）. ③ Compared with the normal group， the model group showed increased adipocyte diameter in iWAT and BAT and decreased number of adipocytes per unit area. Compared with the model group， the TSPJ groups showed significantly reduced cell diameter and increased number of cells per unit area， especially in the high-dose TSPJ group. ④ Compared with the normal group， the model group showed decreased mRNA expression of FABP4， UCP1， CytC， PRDM16， ELOVL3， PGC-1α， and PPARγ in adipose tissues of mice （P<0.05， P<0.01）. Compared with the model group， after intervention with TSPJ， the mRNA expression was significantly up-regulated （P<0.05， P<0.01）. ⑤ Compared with the normal group， the model group showed decreased protein expression of UCP1， PRDM16， PPARγ， and PGC-1α in adipose tissues of mice （P<0.05， P<0.01）. Compared with the model group， after intervention with TSPJ， the protein expression increased significantly （P<0.05， P<0.01）. ConclusionTSPJ could induce the browning of iWAT/BAT activation and enhance adaptive thermogenesis in obese mice induced by HFD. The underlying mechanism may be attributed to the activation of the PPARγ/PGC-1α signaling pathway.

Lo clásico y lo nuevo en el tratamiento del sobrepeso y la obesidad / The classic and the new in the treatment of overweight and obesity

Use of FGF21 analogs for the treatment of metabolic disorders: a systematic review and meta-analysis

ABSTRACT FGF21 is a hormone produced primarily by the liver with several metabolic functions, such as induction of heat production, control of glucose homeostasis, and regulation of blood lipid levels. Due to these actions, several laboratories have developed FGF21 analogs to treat patients with metabolic disorders such as obesity and diabetes. Here, we performed a systematic review and meta-analysis of randomized controlled trials that used FGF21 analogs and analyzed metabolic outcomes. Our search yielded 236 articles, and we included eight randomized clinical trials in the meta-analysis. The use of FGF21 analogs exhibited no effect on fasting blood glucose, glycated hemoglobin, HOMA index, blood free fatty acids or systolic blood pressure. However, the treatment significantly reduced fasting insulinemia, body weight and total cholesterolemia. None of the included studies were at high risk of bias. The quality of the evidence ranged from moderate to very low, especially due to imprecision and indirection issues. These results indicate that FGF21 analogs can potentially treat metabolic syndrome. However, more clinical trials are needed to increase the quality of evidence and confirm the effects seen thus far.

Maternal overweight and obesity before pregnancy as predictors of childhood asthma in children under five years: a retrospective cohort in Peru / Sobrepeso y obesidad materna antes del embarazo como predictores de asma infantil en menores de cinco años: una cohorte retrospectiva en Perú

Abstract Objectives: to estimate the role of maternal overweight and obesity before pregnancy as predictors of childhood asthma in a population of Peruvian children under five years. Methods: we carried out a retrospective cohort study of children aged five years or less and their mothers from the Regional Hospital of Ayacucho and the María Auxiliadora Hospital in Lima, Peru. We included children who were born between 2013 and 2014 and follow them up until 2018 and 2019, respectively. The diagnosis of overweight and obesity of the mother before pregnancy and asthma in the child were registered in their clinical histories. Crude (cRR) and adjusted relative risks (aRR) and 95% confidence intervals (CI95%) were obtained using a generalized lineal model of the Poisson family with link log and robust variances. Results: we evaluated 431 medical records and found that 20.9% of the children had asthma, 26.7% of the mothers were overweight, and 20.2% were obese before pregnancy. In the adjusted regression model, overweight (aRR=2.94; CI95%= 1.54-5.60) and maternal obesity (aRR=5.10; CI95%= 2.73-9.51) were predictors of an increased risk of childhood asthma. Conclusions: maternal overweight and maternal obesity increased the risk of her children developing asthma threeand five-fold, respectively.

Resumen Objetivos: estimar el papel del sobrepeso y la obesidad materna antes del embarazo como predictores de asma infantil en una población de niños peruanos menores de cinco años. Métodos: realizamos un estudio de cohorte retrospectivo de niños de cinco años o menos y sus madres del Hospital Regional de Ayacucho y del Hospital María Auxiliadora de Lima, Perú. Se incluyeron niños nacidos entre 2013 y 2014 y se les dio seguimiento hasta 2018 y 2019, respectivamente. El diagnóstico de sobrepeso y obesidad de la madre antes del embarazo y asma en el niño fueron registrados en sus historias clínicas. Los riesgos relativos crudos (cRR) y ajustados (RRa) y los intervalos de confianza del 95% (IC95%) se obtuvieron mediante un modelo lineal generalizado de la familia de Poisson con log de enlace y varianzas robustas. Resultados: se evaluaron 431 historias clínicas y se encontró que el 20,9% de los niños tenían asma, el 26,7% de las madres tenían sobrepeso y el 20,2% eran obesas antes del embarazo. En el modelo de regresión ajustada, el sobrepeso (aRR=2,94; IC95%= 1,54-5,60) y obesidad materna (RRa=5,10; IC95%= 2,73-9,51) fueron predictores de un mayor riesgo de asma infantil. Conclusiones: el sobrepeso materno y la obesidad materna aumentaron tres y cinco veces el riesgo de que sus hijos desarrollaran asma, respectivamente.

Association of dietary patterns and body phenotypes in Brazilian adolescents / Associação entre padrões alimentares e fenótipos corporais em adolescentes brasileiros

Abstract Objectives: to investigate the association between dietary patterns, physical activity, and body phenotypes in adolescents. Methods: this school-based cross-sectional study involved 1,022 adolescents aged ten to 19 years. Dietary patterns and body phenotypes were defined using a principal component analysis. Body phenotype was defined using anthropometry, body composition, biochemistry, sexual maturation, and dietary patterns from 19 food groups, using a food frequency questionnaire. The association between the dietary patterns and body phenotypes was assessed using a linear regression model. Results: five body phenotypes (BP1adiposity, BP2puberty, BP3biochemical, BP4muscular, BP5lipids_biochemical) and five dietary patterns (DP1ultraprocessed_foods, DP2fresh_foods, DP3bread_rice_beans, DP4culinary_preparations, DP5cakes_rice_beans) were identified. There were higher BP_adiposity scores for obese adolescents, but energy expenditure was similar for obese and non-obese adolescents. Physical activity was positively associated with BMI, BP_adiposity, and BP_puberty. We observed a negative association between DP_ultraprocessed_foods and BMI, and a positive association between DP_fresh_food. DP_fresh_foods was positively associated with BP_adiposity; DP_ultraprocessed_foods and DP_culinary_preparations were negatively associated with this phenotype. BP_biochemical was negatively associated with DP_fresh_foods. Conclusion: we identified a negative association between a dietary pattern composed mainly of ultra-processed foods, fresh foods, and BP_adiposity. These associations need to be better explored, especially in adolescents, as both dietary patterns and phenotypes were defined using multivariate analysis.

Resumo Objetivos: investigar associação entre padrão alimentar (PA), atividade física (AF) e fenótipos corporais (FC) em adolescentes. Métodos: estudo transversal de base escolar com 1.022 adolescentes de dez a 19 anos. Padrão alimentar e fenótipo corporal foram definidos por meio da análise de componentes principais. O fenótipo corporal foi definido usando antropometria, composição corporal, bioquímica e maturação sexual, e padrão alimentar a partir de 19 grupos de alimentos de um questionário de frequência alimentar. A associação entre padrão alimentar e fenótipo corporal foi avaliada por modelo de regressão linear. Resultados: foram identificados cinco fenótipos corporais (FC1adiposidade, FC2puberdade, FC3bioquímico, FC4muscular, FC5lipídios_bioquímico) e cinco padrões alimentares (PA1alimentos_ultraprocessados, PA2alimentos_frescos, PA3pão_arroz_feijão, PA4preparações_culinárias, PA5bolos_arroz_feijão). Há maiores escores de FC_adiposidade para adolescentes com obesidade, mas o gasto energético foi semelhante para adolescentes com e sem diagnóstico de obesidade. Atividade física associou-se positivamente com IMC, FC_adiposidade e FC_puberdade. Observamos associação negativa entre PA_ultraprocessados e IMC, e positiva entre PA_alimentos_frescos. PA_alimentos_frescos associou-se positivamente com FC_adiposidade; PA_ultraprocessados e PA_preparações_culinárias se associaram negativamente a este fenótipo. FC_bioquímico associou-se negativamente com PA_alimentos_frescos. Conclusão: identificamos associação negativa entre padrão alimentar composto principalmente por alimentos ultraprocessados e alimentos in natura e FC_adiposidade. Essas associações devem ser exploradas com o mesmo público em estudos futuros, principalmente em adolescentes, pois tanto o padrão alimentar quanto o fenótipo foram definidos por meio de análise multivariada.
