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.

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.

Braquioplastia no paciente ex-obeso: proposta de classificação / Brachioplasty in ex-obese patients: proposed classification

Introdução: O tratamento cirúrgico da obesidade mórbida implicou na maior demanda por procedimentos reparadores das sequelas causadas pela perda ponderal. Braquioplastia trata o excesso de pele e lipodistrofia localizada nas regiões dos braços e axilas. Os procedimentos para correção de deformidade braquial são incompletos e resultam em cicatrizes insatisfatórias. Sendo assim, propomos uma classificação objetiva que sugere tratamento cirúrgico com vistas à obtenção de um contorno braquial adequado. O objetivo é propor classificação para avaliar lipodistrofia e flacidez cutânea na região dos braços e axilas no paciente ex-obeso e sugerir tratamento cirúrgico adequado. Método: Revisão da literatura e proposta de classificação que sugere opção de tratamento cirúrgico a partir do exame físico pré-operatório. Tal classificação é objetiva e abrangente, facilitando a padronização entre os cirurgiões plásticos. Resultados: A classificação LC se divide em 7 tipos. Tipo L - lipodistrofia sem flacidez; Tipo C1 - flacidez proximal sem lipodistrofia; Tipo C2 - flacidez até terço médio sem lipodistrofia; Tipo C3 - flacidez até terço distal sem lipodistrofia; Tipo LC1 - flacidez em terço proximal com lipodistrofia associada; Tipo LC2 - flacidez até terço médio com lipodistrofia; Tipo LC3 - flacidez até terço distal com lipodistrofia. Baseado na classificação, as denominadas "L" se beneficiam de lipoaspiração enquanto as denominadas "C" sugerem dermolipectomia cirúrgica. Conclusão: A classificação alinha deformidades preexistentes com a respectiva modalidade cirúrgica para correção de cada caso, portanto, a existência de uma classificação objetiva e prática facilita a comunicação e orienta o melhor tratamento, proporcionando ao paciente um contorno braquial adequado.

Introduction: Surgical treatment of morbid obesity has resulted in a greater demand for repairing procedures for sequelae caused by weight loss. Brachioplasty treats excess skin and localized lipodystrophy in the arm and armpit regions. Procedures for brachial deformity correction are incomplete and result in unsatisfactory scars. Therefore, we propose an objective classification that suggests surgical treatment intending to obtain an adequate brachial contour. The aim is to propose a classification to assess lipodystrophy and skin flaccidity in the arms and armpits in ex-obese patients and suggest adequate surgical treatment. Method: Literature review and classification proposal that suggests a surgical treatment option based on the preoperative physical examination. This classification is objective and comprehensive, facilitating standardization among plastic surgeons. Results: The LC classification is divided into 7 types. Type L - lipodystrophy without sagging; Type C1 - proximal flaccidity without lipodystrophy; Type C2 - sagging up to the middle third without lipodystrophy; Type C3 - flaccidity up to the distal third without lipodystrophy; Type LC1 - sagging in the proximal third with associated lipodystrophy; Type LC2 - sagging up to the middle third with lipodystrophy; Type LC3 - sagging up to the distal third with lipodystrophy. Based on the classification, those labeled "L" benefit from liposuction, while those labeled "C" suggest surgical dermolipectomy. Conclusion: The classification aligns preexisting deformities with the respective surgical modality for correction in each case; therefore, an objective and practical classification facilitates communication and guides the best treatment, providing the patient with an adequate brachial contour.

Perda de peso como preditor de mau prognóstico em pacientes hospitalizados com COVID-19 / Weight loss as a predictor of poor prognosis in patients hospitalized for COVID-19

Objetivo: Avaliar a relação entre a perda de peso com marcadores de mau prognóstico em pacientes hospitalizados com COVID-19 no estado de Pernambuco. Métodos: Estudo multicêntrico, transversal, acoplado a algumas variáveis de análise prospectiva envolvendo 71 indivíduos com COVID-19 admitidos para internação em 8 hospitais públicos de Recife, no Estado de Pernambuco. Foram incluídos indivíduos de ambos os sexos, com idade ≥ 20 anos, hospitalizados, no período de junho de 2020 a junho de 2021. Foram coletados dados sociodemográficos, clínicos, nutricionais e marcadores prognósticos. Resultados: A média de idade foi 54,6±15,6 anos, sendo 54,9% dos indivíduos do sexo masculino. Verificou-se que 26,8% dos pacientes eram diabéticos e 52,1% eram hipertensos. O perfil antropométrico indicou 56,3% de excesso de peso e 5,6% de baixo peso. Observou-se rastreio positivo para sarcopenia em 16,9%. A mediana da perda de peso foi 3,1% (0,0-6,6%), sendo uma perda > 5% evidenciada em 29,6% da amostra. Verificou-se que a perda de peso foi mais frequente nos homens (16 (41,0%) vs. 5 (15,6%); p = 0,020) e que as variáveis demográficas, clínicas e nutricionais não se associaram à redução do peso corporal. Não houve associação estatística entre a perda de peso e as variáveis prognósticas (p NS). Conclusão: embora o estudo não tenha demonstrado associação entre a perda de peso e variáveis prognósticas, esta deve ser considerada na avaliação do paciente com COVID-19, devendo ser investigada e tratada como uma importante medida de promoção à saúde.

Objective: To evaluate the relationship between weight loss and markers of poor prognosis in patients hospitalized with COVID-19 in the state of Pernambuco. Methods: A multicenter, cross-sectional study coupled with prospective analysis variables involving 71 individuals with COVID-19 admitted for hospitalization in 8 public hospitals in Recife, in the State of Pernambuco. Individuals of both sexes, aged ≥ 20 years, hospitalized from June 2020 to June 2021 were included. Sociodemographic, clinical, and nutritional data and prognostic markers were collected. Results: The average age was 54.6±15.6 years, with 54.9% of individuals being male. It was found that 26.8% of the patients were diabetic and 52.1% were hypertensive. The anthropometric profile indicated that 56.3% were overweight and 5.6% were underweight. Positive screening for sarcopenia was observed in 16.9%. The median weight loss was 3.1% (0.0-6.6%), with a loss > 5% evident in 29.6% of the sample. It was found that weight loss was more frequent in men (16 (41.0%) vs. 5 (15.6%); p = 0.020) and that demographic, clinical, and nutritional variables were not associated with body weight loss. There was no statistical association between weight loss and prognostic variables (p NS). Conclusion: Although the study did not demonstrate an association between weight loss and prognostic variables, this should be considered when assessing patients with COVID-19 and should be investigated and treated as an essential health promotion measure.

Factors associated with extreme weight loss behaviors among adolescents of Northeastern Brazil: a hierarchical approach / Comportamentos extremos para perda de peso e fatores associados em adolescentes do Nordeste brasileiro: uma abordagem hierárquica

Abstract The objective of this article is to identify the prevalence and evaluate the factors associated with extreme weight loss behaviors among adolescents of Northeastern Brazil. Cross-sectional study with 2,439 adolescents from Sample 2 (2015) of the National School-based Health Survey. Extreme weight loss behaviors, such as self-induced vomiting, laxative use and use of medicines or formulas (outcome) and independent variables were evaluated using a self-administered electronic questionnaire. The statistical analysis was performed following a hierarchical conceptual model. The prevalence of extreme weight loss behaviors in the sample was 12.1%. Among the factors that showed significant association with the outcome, we emphasize the administration model of the private school (PR = 0.62; CI = 0.46-0.84), bullying related to body appearance and for other reasons (PR = 1.62; CI = 1.19-2.20), forced sexual intercourse (PR = 2.65; CI = 1.90-3.69), insomnia (PR = 1.84; CI = 1.43-2.37), and be perceived as fat or very fat (PR = 1.90; CI = 1.50-2.42). Moderate prevalence of extreme weight loss behaviors was identified among adolescents. Socioeconomic factors, exposure to violence, mental health, and body image were associated with the adoption of these behaviors.

Resumo O objetivo deste artigo é identificar a prevalência e avaliar os fatores associados aos comportamentos extremos para perda de peso em adolescentes do Nordeste brasileiro. Estudo transversal com 2.439 adolescentes da Amostra 2 (2015) da Pesquisa Nacional de Saúde do Escolar. Os comportamentos extremos para perda de peso (desfecho) e as variáveis independentes foram avaliadas por meio de um questionário eletrônico autoaplicável. A análise estatística foi realizada seguindo um modelo conceitual hierárquico. A prevalência de comportamentos extremos para perda de peso na amostra foi de 12,1%. Entre os fatores que mostraram associação significativa com o desfecho, destacam-se a situação administrativa da escola privada (RP = 0,62; IC = 0,46-0,84), ser vítima bullying relacionado à aparência corporal e pelos demais motivos (RP = 1,62; IC = 1,19-2,20), ser forçado a ter relação sexual (RP = 2,65; IC = 1,90-3,69), ter insônia (RP = 1,84; IC = 1,43-2,37) e se autoperceber como gordo ou muito gordo (RP = 1,90; IC = 1,50-2,42). Prevalência moderada de comportamentos extremos para perda de peso foi identificada entre os adolescentes. Os fatores socioeconômicos, de exposição à violência, de saúde mental e da imagem corporal se associaram à adoção de tais comportamentos.

Perda de peso e qualidade de vida após o Bypass Gástrico de Anastomose Única: resultados de um seguimento de 2 anos / Weight loss and quality of life after one anastomosis gastric bypass: a 2-year follow-up study

ABSTRACT Background: Studies assessing quality of life (QoL) after one anastomosis gastric bypass (OAGB) are currently scarce. Objective: To analyze the main weight loss outcomes and QoL in individuals undergoing OAGB during a 2-year follow-up. Methods: This is a retrospective study based on a prospectively collected database including individuals which underwent OAGB at a tertiary-level university hospital. After 2-years, excess weight loss was assessed, and post-surgical therapeutical success was determined using Reinhold's criteria. QoL was assessed through the Bariatric Analysis and Reporting Outcomes System (BAROS). Results: Out of 41 participants, 90.2% were female and the average age was 38±8.3 years old. The average body mass index significantly decreased from 37.1±5.6 kg/m2 to 27±4.5 kg/m2 after 2-years (P< 0.001). The mean percentage of excess weight loss was 84.6±32.5%. Regarding weight loss outcomes, 61% were considered "excellent", while 26.8% were "good" according to Reinhold's criteria. With regards to QoL assessed by BAROS, most individuals achieved a score classified as either "excellent" (26.8%), "very good" (36.6%), or "good" (31.7%). The highest degrees of satisfaction achieved were in the domains "self-esteem" and "work capacity", in which 75.6% and 61%, respectively, were classified as "much better". Conclusion: OAGB associated with significant weight loss and resolution of obesity-related medical conditions, as well as relevant QoL improvement assessed by the BAROS system.

Objetivo: Analisar os principais resultados de perda de peso e QV em indivíduos submetidos ao BGAU ao longo de 2 anos de seguimento. Métodos: Este é um estudo retrospectivo baseado em um banco de dados coletado prospectivamente que incluiu indivíduos submetidos ao BGAU em um hospital universitário de nível terciário. Após 2 anos, foi analisado o percentual de perda do excesso de peso (%PEP) e o sucesso terapêutico pós-cirúrgico foi classificado através critérios de Reinhold. A qualidade de vida foi avaliada por meio do Bariatric Analysis and Reporting Outcomes System (BAROS). Resultados: Dos 41 participantes, 90,2% eram do sexo feminino e a idade média foi de 38±8,3 anos. O índice de massa corporal médio diminuiu significativamente de 37,1±5,6 kg/m2 para 27±4,5 kg/m2 após 2 anos (P<0,001). O %PEP médio foi de 84,6±32,5%. Quanto à avaliação dos resultados de perda de peso, 61% foram considerados "excelentes", enquanto 26,8% foram "bons" segundo os critérios de Reinhold. Com relação à QV avaliada pelo BAROS, a maioria dos indivíduos obteve escores classificados como "excelente" (26,8%), "muito bom" (36,6%) ou "bom" (31,7%). Os maiores graus de satisfação alcançados foram nos domínios "autoestima" e "capacidade para o trabalho", nos quais 75,6% e 61%, respectivamente, foram classificados como "muito melhor". Conclusão: O BGAU associou-se à significativa perda de peso e resolução de comorbidades, bem como melhora relevante da qualidade de vida avaliada pelo sistema BAROS.

Managing Low and Moderate Risk Obesity: Insights from a Colombian Reference Center's Experience with Liquid-Filled Intragastric Balloons

Introduction: Liquid-filled intragastric balloons (IGBs) have emerged as a safe and effective option for managing overweight and obesity. However, there is limited information available regarding the implementation of liquid IGBs in individuals with low- and moderate-risk obesity. Objective: The objective of this study was to assess the implementation of liquid IGBs in low- and moderate-risk obese individuals in terms of weight loss, safety, and tolerance at four, six, and twelve months of treatment. Materials and methods: This prospective, descriptive observational study included 109 subjects with low- and moderate-risk obesity (body mass index [BMI] of 30-40 kg/m2), who underwent endoscopic implantation of liquid-filled IGBs. The variables analyzed included sex, age, initial and final weight, percentage of weight loss, and side effects. Results: Out of the 109 subjects, 75.22% were women. The average weight at baseline was 87.22 kg, with an average BMI of 31.59 kg/m2. Three different brands of IGBs were used: Orbera (n=103), Spatz3 (n=3), and Elipse (n=3). The average weight loss showed significant differences when analyzed by months and brands-Ellipse: four months (-4.6 kg), Spatz3: three months (-7 kg), Orbera: six months (15.2 kg), Orbera: twelve months (19.7 kg). The average reduction in BMI achieved was 27.71 kg/m2. The complication rate was 2.75%, with two cases (1.83%) attributed to intolerance (abdominal pain) and one case due to acute appendicitis (0.91%). Conclusions: The findings of this study indicate that liquid-filled IGBs are a safe and effective procedure for managing low- and moderate-risk obesity. A minimum duration of twelve months with an IGB implantation is considered optimal for individuals with low- and moderate-risk obesity.

Materiales y métodos: estudio observacional prospectivo y descriptivo, se incluyeron a 109 sujetos con obesidad de riesgo bajo y moderado (índice de masa corporal [IMC] de 30 a 40 kg/m2), a quienes se les implantó por vía endoscópica un BIG de llenado líquido. Se analizaron las variables de sexo, edad, peso inicial y final, porcentaje de pérdida de peso y efectos secundarios. Resultados: 109 sujetos, 75,22% correspondieron a mujeres, el peso promedio fue de 87,22 kg, con IMC promedio de 31,59 kg/m2. Se usaron tres marcas (Orbera, n: 103; Spatz, 3, n: 3; y Elipse, n: 3). La pérdida de peso promedio presentó diferencias importantes al analizar por meses y marcas: Elipse: 4 meses (-4,6 kg), Spatz 3: 3 meses (-7 kg), Orbera: 6 meses (15,2 kg), Orbera: 12 meses (19,7 kg). Se logró la reducción del IMC promedio a 27,71 kg/m2. La tasa de complicaciones fue del 2,75%, 2 (1,83%) por intolerancia (dolor abdominal) y una por apendicitis aguda (0,91%). Conclusiones: El BIG de llenado líquido es un procedimiento seguro y eficaz. Un período de implantación del BIG de al menos 12 meses se considera óptimo para obesidad de riesgo bajo y moderado.

Hallazgos clínicos, epidemiológicos, histológicos y anatómicos en pacientes adultos con diagnóstico de cáncer de páncreas / Clinical, Epidemiological, Histological and Anatomical Findings in Adult Patients Diagnosed with Pancreatic Cancer

Introducción: El cáncer de páncreas constituye un problema de salud debido al diagnóstico tardío, su agresividad biológica y la ausencia de un tratamiento sistémico efectivo. Objetivo: Caracterizar clínica, epidemiológica, histológica y anatómicamente a pacientes con cáncer de páncreas. Métodos: Se realizó un estudio descriptivo de casos clínicos, en pacientes con cáncer de páncreas que acudieron al Hospital Oncológico Conrado Benítez; de Santiago de Cuba, en el período comprendido diciembre 2017 hasta diciembre 2018. El universo estuvo conformado por el total de los pacientes de ambos sexos, cuya cifra ascendió a 19 que cumplieron con los criterios de inclusión. Resultados: No existió predominio significativo según el sexo, prevaleció el grupo de edades entre 61-70 años en un 31,6 por ciento, el 84,2 por ciento de los pacientes presentó como factor de riesgo la dieta rica en grasas y pobre en verduras y el tabaquismo, en el 63,2 por ciento coexistió la hipertensión arterial, la pérdida de peso fue el signo que sobresalió en el 79,0 por ciento. El 47,4 por ciento se les diagnosticó adenocarcinoma poco diferenciado, siendo la localización más frecuente de los tumores (31,6 por ciento) la cabeza del páncreas. Conclusiones: El cáncer de páncreas es una enfermedad maligna que se relacionada con la edad y sus síntomas se manifiestan tardíamente, se asocia con la presencia de factores de riesgo por lo que es necesario identificarlos precozmente, modificarlos y/o atenuarlos(AU)

Introduction: Pancreatic cancer constitutes a health problem due to late diagnosis, its biological aggressiveness and the absence of effective systemic treatment. Objective: To clinically, epidemiologically, histologically and anatomically characterize patients with pancreatic cancer. Methods: A descriptive study of clinical cases was carried out in patients with pancreatic cancer who attended the Conrado Benítez; Oncological Hospital of Santiago de Cuba, in the period from December 2017 to December 2018. The universe was made up of the total number of patients of both genders, which amounted to 19 meeting the inclusion criteria. Results: There was no significant predominance according to gender, the age group between 61-70 years prevailed in 31.6 percent, 84.2 percent of patients presented as risk factor the diet rich in fat and poor in vegetables and smoking, in 63.2 percent coexisted arterial hypertension, weight loss was the sign that stood out in 79.0 percent. The 47.4 percent were diagnosed with poorly differentiated adenocarcinoma, being the pancreatic head the most frequent location of the tumors (31.6 percent). Conclusions: Pancreatic cancer is an age-related malignant disease and its symptoms manifest late that is associated with the presence of risk factors, so it is necessary to identify them early, modify and/or attenuate them(AU)

Upper airway modifications after weight loss: a systematic review

Abstract Objective: Weight loss is one of the most often prescribed treatments to reduce the level of sleep apnea severity; however, objective assessment of airway alterations after loss of weight has only been studied in the last decades. This study aimed at evaluating alterations after weight loss reported in the literature. Methods: A literature review was performed in the medical databases: PubMed, Web of Science, Scopus and Embase. A total of 681 articles were found in the databases and after evaluation only 10 studies were selected for data extraction. Results: Most studies observed an increase of the area in the retropalatal region; some indicating that this increase occurred mostly in the lateral pharyngeal region. Studies with volumetric reconstruction showed a significant reduction in parapharyngeal fat deposits, lateral wall and tongue fat, and volumetric reduction in all soft tissues of the pharynx, pterygoid and genioglossus muscles. Studies evaluating craniofacial bone structures showed a reduction in the airway height by bringing the hyoid closer to the posterior nasal spine and a reduction in the distance from the hyoid to the chin. Conclusion: There is a limited number of studies with a good level of scientific evidence evaluating changes in the upper airways after weight loss and how these changes impact obstructive sleep apnea. The studies included in this review indicate that weight loss increases the airways space by reducing the volume of the parapharyngeal structures, particularly at the retropalatal site, where there is an apparent gain in the lateral area of the airway and hyoid relocation.

Analysis of post-bariatric plastic surgeries performed in the Brazilian Unified Health System / Análise das cirurgias plásticas pós-bariátricas realizadas no Sistema Único de Saúde

Introduction: Obesity and overweight have been increasing in Brazil and in the world, in an expressive way, as well as the demand for bariatric surgeries. As a result, post-bariatric plastic surgery has also grown, especially abdominal dermolipectomy. The objective is to describe the frequency of post-bariatric plastic surgeries performed by the Unified Health System (SUS - Sistema Único em Saúde, in portuguese) from January 1, 2015 to October 21, 2020. Methods: Ecological study, where individuals who underwent post-bariatric surgeries were selected. bariatric tests by SUS obtained by the Hospital Information System of Department of Informatics of the Unified Health System (DATASUS - Departamento de Informática do Sistema Único de Saúde, in portuguese). Data from the 27 states of the national territory were analyzed and the following variables were used: gender, age group, procedure performed, level of education. Results: The southeastern region of the country had the highest number of post-bariatric surgeries. White individuals, on the other hand, had higher numbers than other races (60.9%), abdominal dermolipectomy was the most frequent (53.7%) followed by mammoplasty (22.3%). Conclusion: Plastic surgeries have increased significantly in the last five years, and are more frequent among white women, aged between 35 and 44 years, living in the southeastern region of the country.

Introdução: A obesidade e o sobrepeso vêm aumentando no Brasil e no mundo, de uma forma expressiva, assim como a procura por cirurgias bariátricas. Em consequência, a cirurgia plástica pós-bariátrica também cresceu, com destaque para a dermolipectomia abdominal. O objetivo é descrever a frequência das cirurgias plásticas pós-bariátricas feitas pelo Sistema Único de Saúde (SUS) no período de 1 de janeiro de 2015 a 21 de outubro de 2020. Método: Estudo ecológico, no qual foram selecionados indivíduos que realizaram cirurgias pós-bariátricas pelo SUS obtidos pelo Sistema de Informações Hospitalares do Departamento de Informática do Sistema Único de Saúde (DATASUS). Foram analisados dados dos 27 estados do território nacional e utilizaram-se as variáveis: sexo, faixa etária, procedimento realizado, grau de instrução.

Obesidad e hipertensión arterial y su relación con la pérdida de peso

La obesidad es una acumulación anormal y excesiva de grasa perjudicial para la salud con impacto negativo en la calidad de vida, asociada comorbilidades como la hipertensión arterial. En 2015 se estimaba 603,7 millones de adultos con obesidad en el mundo. Los datos de NHANES consideran un aumento progresivo de obesidad y sobrepeso en los últimos 30 años que paso de 22,9% a 42,4%. En Ecuador 6 de cada 10 personas tienen sobrepeso u obesidad. La hipertensión en la obesidad está determinada con mayor frecuencia por el envejecimiento vascular acelerado por procesos inflamatorios, estrés oxidativo y resistencia a la insulina. Las modificaciones en el estilo de vida determinan que por cada 1 kg de pérdida de peso disminuye a corto plazo 1 mmHg de la presión arterial sistólica. La cirugía bariátrica posee un impacto en la pérdida de peso y los factores cardiovasculares. Los registros epidemiológicos han demostrado una relación lineal directa entre la obesidad y la presión arterial: a medida que aumenta el peso, aumenta la presión arterial. De la misma manera, el efecto de reducción de la presión arterial sobre la pérdida de peso parece ser lineal: a mayor pérdida de peso mayor disminución de la presión arterial.

Obesity is an abnormal and excessive accumulation of fat that is detrimental to health with a negative impact on quality of life, associated with comorbidities such as arterial hypertension. In 2015, it was estimated that there were 603.7 million obese adults in the world. The NHANES data consider a progressive increase in obesity and overweight in the last 30 years, from 22.9% to 42.4%. In Ecuador 6 out of 10 people are overweight or obese. Hypertension in obesity is most often determined by vascular aging accelerated by inflammatory processes, oxidative stress, and insulin resistance. Changes in lifestyle determine that for every 1 kg of weight loss, there is a short-term reduction of 1 mmHg in systolic blood pressure. Bariatric surgery has an impact on weight loss and cardiovascular factors. Epidemiological records have shown a direct linear relationship between obesity and blood pressure: as weight increases, blood pressure increases. Similarly, the effect of blood pressure reduction on weight loss appears to be linear: the greater the weight loss, the greater the decrease in blood pressure.

Hibiscus Tea and its Therapeutic Potential in Weight Reduction: Integrative Review / Chá de Hibiscus e seu Potencial Terapêutico na Redução de Peso: Revisão Integrativa

The calyx of the Hibiscus plant are used in the form of an infusion in popular medicine with the purpose of contributing to the weight loss of its users. Therefore, the objective of this work was to verify in the literature the therapeutic potential of Hibiscus sabdariffa tea for weight loss. This is an integrative review done in the following databases: Scopus, PubMed, Science Direct, Web of Science. The final sample consisted of 6 articles. Half of the selected articles had the clear objective of evaluating weight loss, the others evaluated anti-metabolic and anti-stress properties, obesity-related adipogenesis and control of lipid indicators. In the selected studies, the most used part of the plant was the calyx, being fresh and dry. Factors such as the concentration and form of supply of the Hibiscus sabdariffa extract seem to be points to be taken into account in experiments that have food intake as an influence on the other variables. The studies brought evidence that Hibiscus sabdariffa extracts contribute to weight loss and to the suppression of weight gain in human and animal groups with metabolic disorders, without change for the healthy human/animal group. However, studies on the long-term maintenance of weight loss, once achieved, the efficacy and safety of its use, are still insufficient according to the collected evidence.(AU)

Os cálices da planta Hibiscus são utilizados na forma de infusão na medicina popular com o propósito de contribuir na perda ponderal de seus usuários. Diante disto, o trabalho teve como objetivo verificar na literatura o potencial terapêutico do chá de Hibiscus sabdariffa para a perda ponderal. Trata-se de uma revisão integrativa realizada nas bases: Scopus, PubMed, Science Direct, Web of Science. A amostra final foi formada por 6 artigos. Metade dos artigos selecionados tinham como objetivo claro avaliar a perda de peso, os demais avaliavam as propriedades antimetabólicas e antiestresse, adipogênese relacionada à obesidade e controle dos indicadores lipídicos. Nos estudos selecionados, a parte da planta mais utilizada foi o cálice, sendo eles frescos e secos. Fatores como a concentração e a forma de fornecimento do extrato do Hibiscus sabdariffa parecem ser pontos a serem levados em consideração em experimentos que tenham a ingestão alimentar como influência sobre as demais variáveis. Os estudos trouxeram evidencias de que os extratos de Hibiscus sabdariffa contribuem para a perda de peso e para a supressão do ganho de peso em grupos humanos e animais com disfunções metabólicas, sem alteração para o grupo de humanos/animais saudáveis. No entanto, estudos sobre a manutenção a longo prazo da perda de peso, uma vez alcançada, a eficácia e segurança de seu uso, ainda são insuficientes de acordo com as evidências coletadas.(AU)

CHALLENG TO OBESITY; COVER WEIGHT LOSS BY CONSUMPTION OF INDIAN MILLETS.

Obesity is a pathological condition in which excessive body fat accumulated leading adverse effect on health and life expectancy. [1]. Obesity is a chronic disorder with complex interaction between genetic and environmental factor. It characterized by high cholesterol, high fatty acid level, imbalance of metabolic energy, insulin desensitization, gallstone, high blood presser, shortness of breath, emotional and social problem and excessive adipose mass accumulation with hyperplasia and hypertrophy.[2]. In the present study method that had been used for preventing weight gain by meal, replacement and given some quantitative dose of millet, at one time dinner. So in this method level of compliance is better by giving the nutrient intake food, to controlled calories density of the body of patient, which enhances effect of weight loss

El ayuno intermitente y sus efectos en la salud metabólica en humanos / Intermittent fasting and human metabolic health

Intermittent fasting (IF) has gained increasing scientific and general attention. Most studied forms of IF include alternate-day fasting, modified alternate-day fasting, and time-restricted eating (TRE). Several cardiometabolic effects of IF have been described in animal models and, to a lesser extent, in humans. This review analyzes the impact of IF on weight loss, glucose metabolism, blood pressure, and lipid profile in humans. A literature search was conducted in the Pubmed/Medline, Scopus, and Google Scholar databases. Controlled observational or interventional studies in humans, published between January 2000 and June 2021, were included. Studies comparing IF versus religious fasting were not included. Most studies indicate that the different types of IF have significant benefits on body composition, inducing weight loss and reducing fat mass. Changes in cardiometabolic parameters show more divergent results. In general, a decrease in fasting glucose and insulin levels is observed, together with an improved lipid profile associated with cardiovascular risk. High heterogeneity in study designs was observed, particularly in studies with TRE, small sample sizes, and short-term interventions. Current evidence shows that IF confers a range of cardiometabolic benefits in humans. Weight loss, improvement of glucose homeostasis and lipid profile, are observed in the three types of IF protocols evaluated.

High-intensity functional training with an adequate and carbohydrate restricted hypocaloric diet promotes weight loss and cardiometabolic improvements

INTRODUCTION: Excess body weight and its comorbidities represent a major public health issue. Interventions based on diet and exercise have not only been shown to promote weight loss, but also improve overall health, including cardiovascular health. OBJECTIVE: This study aimed to evaluate the effects of a 12-week hypocaloric low-carbohydrate (CHO) diet coupled with high-intensity functional training (HIFT) on the cardiometabolic risk of overweight adults. METHODS: This is a randomized controlled trial. A total of 31 overweight adults participated in this study, divided into two groups based on the dietary intervention: reduced-CHO (R-CHO, ≤130 g/day; n=15) and adequate-CHO (A-CHO, >130 g/day; n=16). The cardiometabolic risk was assessed using lipidaemic, insulinemia, and glycaemic parameters. A two-way ANOVA with Bonferroni post hoc test was utilized to evaluate the effects of the intervention. A p-value < 0.05 was considered statistically significant. RESULTS: Participants from both groups displayed decreased low-density lipoprotein, very-low-density lipoprotein, total cholesterol, and triacylglycerol concentrations, as well as the number of risk factors for the metabolic disease after 12 weeks. The high-density lipoprotein (HDL) cholesterol concentration of both groups increased after 12 weeks, however, the result of the intragroup analysis revealed that a significant increase was only observed in the participants from the A-CHO group. CONCLUSION: Reduced or adequate CHO intake was both found to be effective in reducing cardiometabolic risk. However, improvements in HDL and final cardiometabolic classification risk indicated that CHO adequacy in the diet might be a better strategy associated with caloric restriction and HIFT.

A infecção por Helicobacter pylori e o resultado de seu tratamento de erradicação influenciam a perda de peso e achados endoscópicos após o bypass gástrico em Y de Roux? Um estudo de coorte histórica / Do helicobacter pylori infection and eradication therapy status influence weight loss outcomes and endoscopic findings after roux-en-y gastric bypass?a historical cohort study

ABSTRACT Background: Currently, there is conflicting evidence linking Helicobacter pylori (HP) infection with weight loss and endoscopic findings after Roux-en-Y gastric bypass (RYGB). Objective: To identify correlations between HP infection and its eradication with weight loss and endoscopic findings after RYGB. Methods: This is an observational retrospective cohort study based on a prospectively collected database of individuals who underwent RYGB from 2018-2019 at a tertiary university hospital. HP infection and the HP eradication therapy outcomes were correlated with post-operative weight loss and endoscopic findings. Individuals were classified according to the status of HP infection into four groups: no infection; successful eradication; refractory infection; and new-onset infection. Results: Of 65 individuals, 87% were female and the mean age was 39±11.2 years. Body mass index significantly decreased from 36.2±3.6 to 26.7±3.3 kg/m2 one year after RYGB (P<0.0001). The percentage of total weight loss (%TWL) was 25.9±7.2% and the percentage of excess weight loss was 89.4±31.7%. HP infection prevalence decreased from 55.4% to 27.7% (p=0.001); 33.8% never had HP infection, 38.5% were successfully treated, 16.9% had refractory infection and 10.8 % had new-onset HP infection. %TWL was 27.3±7.5% in individuals who never had HP, 25.4±8.1% in the successfully treated, 25.7±5.2% in those with refractory infection, and 23.4±6.4% in the new-onset HP infection group; there were no significant differences among the four groups (P=0.6). Pre-operative HP infection significantly associated with gastritis (P=0.048). New-onset HP infections significantly associated with a lower frequency of jejunal erosions after surgery (P=0.048). Conclusion: No effects of the HP infection on weight loss were identified in individuals undergoing RYGB. A higher prevalence of gastritis was observed in individuals with HP infection before RYGB. New-onset HP infection after RYGB was a protective factor for jejunal erosions.

RESUMO Contexto: Há evidências conflitantes na literatura atual ligando a infecção por Helicobacter pylori (HP) com a perda de peso e achados endoscópicos após o bypass gástrico em Y de Roux (BGYR). Objetivo: Identificar correlações entre infecção por Helicobacter pylori HP e seu tratamento de erradicação com perda de peso e achados endoscópicos após BGYR. Métodos: Trata-se de um estudo retrospectivo e observacional de coorte histórica, baseado em um banco de dados coletados prospectivamente de indivíduos submetidos ao BGYR de 2018 a 2019 em um hospital terciário universitário. A infecção pelo HP e os resultados da terapia de erradicação do HP foram correlacionados com a perda de peso pós-operatória e os achados endoscópicos. Os indivíduos foram classificados de acordo com o status de infecção pelo HP em quatro grupos: ausência de infecção; erradicação bem-sucedida; infecção refratária; e infecção nova. Resultados: Dos 65 indivíduos, 87% eram do sexo feminino e a média de idade foi de 39±11,2 anos. O índice de massa corporal diminuiu significativamente de 36,2±3,6 para 26,7±3,3 kg/m2 um ano após BGYR (P<0,0001). O percentual de perda de peso foi 25,9±7,2% e o percentual de perda do excesso de peso foi 89,4±31,7%. A prevalência de infecção por HP diminuiu de 55,4% para 27,7% após a cirurgia (P=0,001); 33,8% nunca tiveram infecção por HP, 38,5% tiveram um tratamento bem-sucedido, 16,9% tiveram infecção refratária e 10,8% tiveram nova infecção por HP. Infecção pré-operatória por HP associou-se significativamente à presença de gastrite (P=0,048). Infecções por HP de início recente associaram-se significativamente com menor frequência de erosões jejunais após a cirurgia (P=0,048). Conclusão: Não foram identificados efeitos da infecção por HP na perda de peso em indivíduos submetidos ao BGYR. Maior prevalência de gastrite foi observada em indivíduos com infecção por HP antes da cirurgia. A infecção por HP de início recente após BGYR foi um fator protetor para erosões jejunais.

Obesity, diabetes, and cancer: epidemiology, pathophysiology, and potential interventions

ABSTRACT The proportion of deaths attributable to cancer is rising, and malignant neoplasms have become the leading cause of death in high-income countries. Obesity and diabetes are now recognized as risk factors for several types of malignancies, especially endometrial, colorectal, and postmenopausal breast cancers. Mechanisms implicated include disturbances in lipid-derived hormone secretion, sex steroids biosynthesis, hyperinsulinemia, and chronic inflammation. Intentional weight loss is associated with a mitigation of risk for obesity-related cancers, a phenomenon observed specially with bariatric surgery. The impact of pharmacological interventions for obesity and diabetes is not uniform: while metformin seems to protect against cancer, other agents such as lorcaserin may increase the risk of malignancies. However, these interpretations must be carefully considered, since most data stem from bias-prone observational studies, and high-quality randomized controlled trials with appropriate sample size and duration are needed to achieve definite conclusions. In this review, we outline epidemiological and pathophysiological aspects of the relationship between obesity, diabetes, and malignancies. We also highlight pieces of evidence regarding treatment effects on cancer incidence in these populations.

Resting energy expenditure depends on energy intake during weight loss in people with obesity: a retrospective cohort study

Abstract Objective: Resting energy expenditure (REE) decreases if there is reduced energy intake and body weight (BW). The decrease in REE could make it difficult for patients with obesity to maintain decreased BW. This study aimed to investigate the correlation among changes in REE, energy intake, and BW during the weight loss process in patients with obesity. Materials and methods: We conducted a retrospective cohort study of patients hospitalized for the treatment of obesity in Japan. Patients received fully controlled diet during hospitalization and performed exercises if able. REE was measured once a week using a hand-held indirect calorimetry. Energy intake was determined by actual dietary intake. Results: Of 44 inpatients with obesity, 17 were included in the analysis. Their BW decreased significantly after 1 week (−4.7 ± 2.0 kg, P < 0.001) and 2 weeks (−5.7 ± 2.2 kg, P < 0.001). The change in REE after 1 and 2 weeks was positively correlated with the energy intake/energy expenditure ratio (r = 0.66, P = 0.004 at 1 week, r = 0.71, P = 0.002 at 2 weeks). Using a regression equation (y = 0.5257x - 43.579), if the energy intake/energy expenditure ratio within the second week was 82.9%, the REE after 2 weeks was similar to the baseline level. There was no significant correlation between the change in REE and BW. Conclusions: Our data suggest that changes in REE depend on energy intake/energy expenditure ratio and that the decrease in REE can be minimized by matching energy intake to energy expenditure, even during the weight loss process.

Effects of resistance training on weight in college students / Efeitos do treinamento de resistência sobre o peso em universitários / Efectos del entrenamiento de resistencia sobre el peso en estudiantes universitarios

ABSTRACT Introduction: Obesity has a great negative impact on college students, affecting their physical and mental health. It is believed that resistance training, as an aerobic exercise that promotes muscle hypertrophy, can promote an obesity-reducing effect in this class of individuals. Objective: Assess the effects of resistance training with loads on weight in college students. Methods: 120 obese college student volunteers were equally and randomly divided into groups for the experiment. The experimental groups A and B received resistance training with different loads, while the control group received only regular aerobic training. For statistical analysis and discussion, body indices such as perimetry and BMI were collected before and after the intervention. Results: After the experiment, the body weight of experimental group A changed from 81.62±4.12 to 76.20±5.49, BMI from 27.22±1.67 to 25.98±1.74, waist circumference from 89.11±5.62 to 87, 27±6.34, hip circumference from 101.61±5.43 to 98.45±5.62, waist/hip ratio from 0.89±2.34 to 0.87±2.13, and body fat ratio from 27.58±3.83 to 22.61±2.99. Significant changes were also noticed in the data of experimental group A after resistance training with different loads. These changes were similar to those of the experimental group B, but changes in the control group data were not evidenced. Conclusion: Resistance training with loads can help obese college students improve their body composition and physical quality. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
