ABSTRACT

Introduction: A prognostic model to predict liver severity in people with metabolic dysfunction-associated steatotic liver disease (MASLD) is very important, but the accuracy of the most commonly used tools is not yet well established. Objective: The meta-analysis aimed to assess the accuracy of different prognostic serological biomarkers in predicting liver fibrosis severity in people with MASLD. Methods: Adults ≥18 years of age with MASLD were included, with the following: liver biopsy and aspartate aminotransferase-to-platelet ratio (APRI), fibrosis index-4 (FIB-4), non-alcoholic fatty liver disease fibrosis score (NFS), body mass index, aspartate aminotransferase/alanine aminotransferase ratio, diabetes score (BARD score), FibroMeter, FibroTest, enhanced liver fibrosis (ELF), Forns score, and Hepascore. Meta-analyses were performed using a random effects model based on the DerSimonian and Laird methods. The study's risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2. Results: In total, 138 articles were included, of which 86 studies with 46,514 participants met the criteria for the meta-analysis. The results for the summary area under the receiver operating characteristic (sAUROC) curve, according to the prognostic models, were as follows: APRI: advanced fibrosis (AF): 0.78, any fibrosis (AnF): 0.76, significant fibrosis (SF): 0.76, cirrhosis: 0.72; FIB-4: cirrhosis: 0.83, AF: 0.81, AnF: 0.77, SF: 0.75; NFS: SF: 0.81, AF: 0.81, AnF: 0.71, cirrhosis: 0.69; BARD score: SF: 0.77, AF: 0.73; FibroMeter: SF: 0.88, AF: 0.84; FibroTest: SF: 0.86, AF: 0.78; and ELF: AF: 0.87. Conclusion: The results of this meta-analysis suggest that, when comparing the scores of serological biomarkers with liver biopsies, the following models showed better diagnostic accuracy in predicting liver fibrosis severity in people with MASLD: FIB-4 for any fibrosis, FibroMeter for significant fibrosis, ELF for advanced fibrosis, and FIB-4 for cirrhosis.Clinical trial registration: [https://clinicaltrials.gov/], identifier [CRD 42020180525].

ABSTRACT

OBJECTIVE: This study aimed to develop the Brazilian instrument for assessing eating disorders in children and adolescents and test its psychometric quality using item response theory (IRT). DESIGN: Cross-sectional study. PARTICIPANTS: Participants aged between five and twelve years old of both sexes. MAIN MEASURES: IRT logistic model of two parameters was used to evaluate the item's severity and discrimination and test information curve of symptoms of eating disorders' latent trait symptoms. Content validity and reliability were also assessed. The IRT evaluation suggested that the instrument contained items that performed differently concerning severity, discrimination, and test information curve presented good accuracy. RESULTS: There was agreement on the clarity of language (83.3%) and theoretical relevance (91.7%), indicating good content validity. The value of the Cronbach's Alpha was 0.63 (95% confidence interval), and the result of the Spearman-Brown test was 0.65. CONCLUSION: These results indicate good performance of the screening tool in assessing the level of eating disorders in children and adolescents.

ABSTRACT

Cirurgia bariátrica é um tratamento eficaz para obesidade mórbida. Alguns fatores psicológicos podem impactar no resultado pós-operatório relacionado à perda de peso. Investigar a influência das expectativas e as motivações pré-operatórias, assim como a presença de outros transtornos psicológicos que têm potencial de estarem ligados ao desfecho desfavorável foi o objetivo desta pesquisa. Este estudo caso-controle retrospectivo considerou 44 casos de fracasso para 88 controles de sucesso em uma amostra randomizada de pacientes operados em um serviço de referência de um hospital escola. Os resultados revelaram que expectativas relacionadas à diminuição do preconceito social e à melhoria da capacidade e condições de trabalho estão associadas à resposta insatisfatória na perda do excesso de peso esperada neste procedimento cirúrgico. Falhas em tratamentos prévios para controle da obesidade foram apontadas como indicador favorável relacionado ao sucesso na perda de peso pós-cirurgia. E não houve associação de outros transtornos psicológicos com o resultado de fracasso


Bariatric surgery is an alternative for morbid obesity treatment. Some factors can impact the postoperative results related to weight loss. The objective of this research was to unveil the influence of preoperative expectations that have the potential to be linked to the unfavorable outcome. This retrospective, case-control study considered 44 cases of failure for 88 success controls in a randomized sample of patients operated on in a Brazilian School Hospital. The results revealed that expectations related to the reduction of social prejudice and the improvement of work capacity and conditions are associated with an unsatisfactory response to the expected excess weight loss in this surgical procedure. Failures in previous treatments for obesity control were identifi ed as a favorable indicator related to success in weight loss after surgery. And there was no association of other psychological disorders with the result of failure

ABSTRACT

BACKGROUND: The aim of this study was to evaluate the influence of the body mass index (BMI) on laboratory, clinical outcomes and treatment costs of assisted reproduction, as there are still controversial and inconclusive studies on this subject. METHODS: This research was retrospective cohort study, including women undergoing assisted reproduction in a Reproductive Medicine Center between 2013 and 2020. The participants were divided into groups according to BMI (kg/m2): Group 1 < 25; Group 2, 25-29.9 and Group 3, ≥ 30. A total of 1753 in vitro fertilization (IVF) fresh embryo transfer (ET) cycles were included for assisted reproduction outcomes analysis and 1869 IVF-ET plus frozen embryo transfer (FET) for cumulative pregnancy analysis. RESULTS: As higher the BMI, higher was the proportion of canceled IVF cycles (G1 (6.9%) vs. G2 (7.8%) vs. G3 (10.4%), p = 0.002) and gonadotropin's total dose (IU) and treatment costs (G1 (1685 ± 595, U$ 683,02) vs. G2 (1779 ± 610, U$ 721,13) vs. G3 (1805 ± 563, U$ 764,09), p = 0.001). A greater number of mature oocytes was observed in G1 and G2 (6 [6.4-7.0] vs. 6 [5.6-6.6] vs. 4 [4.6-6.7], p = 0.011), which was not found in oocyte maturity rate (p = 0.877). A significant linear tendency (p = 0.042) was found in cumulative pregnancy rates, pointing to worse clinical outcomes in overweight and obese patients. CONCLUSION: These findings highlight the importance of considering the higher treatment costs for these patients, beyond all the well-known risks regarding weight excess, fertility, and pregnancy, before starting IVF treatments.

ABSTRACT

BACKGROUND: In spontaneous pregnancies, maternal weight and gestational diabetes are independent risk factors for macrosomia and large-for-gestational-age newborns. Furthermore, maternal body mass index (BMI) of ≥25 kg/m2 is associated with worse neonatal vitality, classified as an Apgar score of < 7 at the fifth minute of life. However, few studies have evaluated the influence of BMI on perinatal outcomes in pregnancies resulting from assisted reproduction. Therefore, this study aimed to analyze whether the perinatal outcomes of assisted reproduction are influenced by BMI. METHODS: This was a retrospective cohort study performed at a reproductive medicine center. Patients undergoing assisted reproduction (2013-2020) were divided into three groups according to their BMI (kg/m2): group 1, < 25; group 2, 25-29.9, and group 3, ≥30. In total, 1753 in vitro fertilization embryo transfer cycles were analyzed. Data were expressed as mean ± standard deviation or frequency (%). The analysis of variance and chi-square test were performed for comparison. To determine the participants and number of cycles for these analyses, generalized estimating equations were used, considering p < 0.05. RESULTS: In groups 1, 2, and 3, the rates of live birth were 33.5, 32.3, and 29.9% (p = 0.668); preeclampsia were 2.9, 6.1, and 6.3% (p = 0.268); small-for-gestational-age newborns were 23, 23.2, and 21.7% (p = 0.965); macrosomia were 1.9, 0.9, and 2.7% (p = 0.708); Apgar score > 7 at the fifth minute were 97.6, 98.2, and 100% (p = 0.616); and preterm birth were 29.6, 30.1, and 35.1% (p = 0.970), respectively. CONCLUSIONS: In conclusion, although the three groups had similar perinatal outcomes in this study, the study population was too small for conclusive results. The higher the BMI, the lower the chances of clinically relevant LBR and the higher the chances of premature labor and preeclampsia.

ABSTRACT

PURPOSE: To draw the attention of the medical community to a differential diagnosis of intestinal obstruction due to bezoar in the late postoperative period of gastric bypass that requires diagnosis and emergency management. METHODS: We report 8 cases of patients with intestinal obstruction due to bezoar in the late postoperative period of gastric bypass who required surgical intervention. CONCLUSION: Intestinal obstruction due to fruit pomace is a late complication that may require urgent surgical intervention and should be considered in the differential diagnosis.

ABSTRACT

PURPOSE: Although bariatric surgery can facilitate weight loss and improve many diseases, it impairs the absorption of many vitamins and micronutrients. Vitamin B12 is important for these patients and should be controlled and supplemented postoperatively. The aim of this paper is to compare serum vitamin B12 levels in two forms of supplementation (oral vs. intramuscular) for 6 months after gastric bypass. METHODS: In a prospective controlled cohort study, people with obesity patients undergoing gastric bypass received vitamin B12 supplementation either orally or intramuscularly. The patients were followed for 6 months, receiving serial doses of vitamin B12 and methylmalonic acid assessment at 6 months. RESULTS: A total of 53 patients were divided into two homogeneous groups: an oral group (n=24) and an intramuscular group (n=29). Serum vitamin B12 was measured preoperatively and postoperatively at 1, 2, 3, and 6 months. Serum methylmalonic acid was measured at 6 months. At each point, the serum vitamin B12 level remained within reference values in both groups, although it was higher in the oral group (p<0.001). Methylmalonic acid also remained within reference values in both groups, with no significant differences. CONCLUSION: Despite the anatomical and functional alterations that impair vitamin B12 absorption after gastric bypass, oral vitamin B12 supplementation was as effective as intramuscular in this population.

ABSTRACT

BACKGROUND: Bariatric surgery is one of the best treatments for obesity. This indication includes an evaluation of body mass index (BMI) that does not consider the body composition of an individual. AIM: To determine the body composition of bariatric surgery candidates. METHODS: Patients treated at a tertiary care centre for obesity were evaluated. Body composition was measured by bioelectrical impedance analysis (BIA). All measures of BIA and surgical indication were analysed. RESULTS: We evaluated 407 subjects, 87 (21.4%) men, with a mean age of 36 years. In men with indications for bariatric surgery, the mean ± SD body fat percentage (%BF) was 45.1 ± 5.39%, and the mean ± SD visceral fat area was 243.6 ± 33.79 cm2. In women with indications for bariatric surgery, the mean ± SD %BF was 50.7 ± 3.3%, and the mean ± SD visceral fat area was 241.7 ± 24.77 cm2. CONCLUSION: This study showed different body compositions between men and women and parameters of %BF and visceral fat area evaluated by BIA.

ABSTRACT

BACKGROUND: One of the most important concerns on health is the increased rates of obesity in population and the speed in which this number is increasing. This number translates a serious public health problem, since it also increases the risk of several other diseases associated with obesity resulting in significant morbidity and mortality. Among them, it seems to be connected to several neoplasms, such as colorectal carcinoma. AIM: To evaluate the impact of obesity as a risk factor for colorectal carcinoma through the detection of adenoma, and to discuss the mechanisms that could establish a link between obesity and neoplasm. METHODS: Patients who underwent colonoscopy were included. Personal and anthropometric data, clinical history, and results of the tests were analyzed in order to verify the correlation of BMI and the presence of adenomatous polyps. RESULTS: A total of 142 patients were studied, which a mean age of 62 years. Of the patients, 74 (52.1%) were men and 68 (47.9%) were. Obesity was identified in 16.2% of the patients. Polyps were found in 61 (42.9%), mostly smaller than 1 cm. Obese individuals were 1.56 times more likely to present colorectal adenoma than patients with normal weight. CONCLUSION: This study, although showing the greater presence of colorectal adenomas in obese individuals, did not show a significant difference in the occurrence of pre-malignant lesions.

RESUMO Racional: Uma das grandes preocupações no âmbito da saúde é o crescente índice de obesidade na população e a velocidade com que esse número vem aumentando. Ele constitui grave problema de saúde pública, uma vez que aumenta também o risco de inúmeras doenças associadas à obesidade e que resultam em morbimortalidade significativa, como o câncer colorretal. Objetivo: Avaliar o impacto da obesidade como fator de risco para câncer colorretal, através da detecção de adenomas colorretais, e discutir os mecanismos que podem estabelecer uma ligação entre esta neoplasia e a obesidade. Métodos: Foram incluídos pacientes submetidos à colonoscopia. Dados pessoais e antropométricos, antecedentes clínicos e laudos dos exames foram analisados, a fim de verificar a correlação do IMC e a presença de pólipos adenomatosos. Resultados: Foram estudados 142 pacientes, 74 (52,1%) homens e 68 (47,9%) mulheres, com média de 62 anos. A obesidade foi identificada em 16,2% dos pacientes. Pólipos foram encontrados em 61 (42,9%), sendo em sua maioria menores do que 1 cm. Obesos tiveram probabilidade 1,56 vez maior de apresentar adenoma colorretal que pacientes com peso normal. Conclusão: Este estudo, apesar de mostrar a maior presença de adenomas colorretais em indivíduos obesos, não mostrou diferença estatisticamente significativa na ocorrência de lesões pré-malignas.

ABSTRACT

BACKGROUND: The potential effect of bariatric surgery on weight reduction and improvement of associated comorbidities is known, but the ratio obtained between the components of body weight, including lean body mass, body fat mass, and bone mass, is still not determined. This study aims to verify the changes in body composition during the first year after bariatric surgery. METHODS: We conducted a prospective observational cohort study. Fifty patients who underwent bariatric surgery and maintained follow-ups were selected. Patients were assessed preoperatively and postoperatively for periods of 1, 3, 6, and 12 months using tetrapolar bioelectrical impedance analysis and laboratory testing of lipids and serum albumin levels. Data were statistically analyzed. RESULTS: Statistically significant differences (p < 0.001) were obtained between the preoperative and 12-month evaluation respectively, for body mass index (BMI) (45.8 ± 7.5 to 30.0 ± 4.8 kg/m2), FM (64.7 ± 15.5 to 30.6 ± 9.8 kg), PFM (51.6 ± 4.17 to 37.3 ± 7.6%), and total cholesterol levels (197.1 ± 49.8 to 169.8 ± 31.0 mg/dL). The decrease in PFM shows a better proportion between the body components. PFM showed significantly higher decrease in males than in females (p = 0.012). Lean body mass (p = 0.000) reduction was highest for patients operated by the Unified Health System (SUS, Government of Brazil) probably because of its few financial resources to maintain postoperative care. CONCLUSION: The change in body composition of patients who underwent Roux-en-Y gastric bypass was statistically significant for all variables examined during the first year postoperatively. This shows the effectiveness of the surgical procedure and clinical protocol set, which tends to favor a better health prognosis and weight maintenance in the long term.

ABSTRACT

OBJECTIVE: To evaluate the relationship between physical activity and phase angle. DESIGN: Systematic Review and Meta-analysis. DATA SOURCES: Electronic searches of MEDLINE (via PUBMED), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), SciELO, LILACS, SPORTDiscus, Scopus, and Web of Science from inception to December 10th, 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: The PICOS strategy was defined, in which "P" corresponded to participants of any age, sex or ethnicity, "I" indicated any type of physical activity program, "C" denoted lack of exercise or irregular physical activity, "O" corresponded to the phase angle obtained by bio-impedance, and "S" indicated longitudinal or cross-sectional studies. RESULTS: In cross-sectional studies the phase angle was higher among the active individuals (MD = 0.70; 95% CI: 0.48, 0.92, P < 0.001), with low heterogeneity (I2 = 0%; P = 0.619). In longitudinal studies, the mean of the difference of phase angles from the baseline was significantly higher for the active group than the control group (MD = 0.30; 95% CI: 0.11, 0.49, P = 0.001), with low heterogeneity (I2 = 13%, P = 0.331). No evidence of publication bias was found and the overall risk of bias was moderate to high. SUMMARY/CONCLUSION: The positive association of physical activity with phase angle reinforces the importance of routinely including exercise in health care. We also identified the need for further studies to define with different types, intensities and frequencies of exercises should be conducted in order to find the best dose-effect relationship.

ABSTRACT

PURPOSE: The aim of this study was to evaluate changes in urinary incontinence (UI) before and after surgery for obesity in female patients and to identify factors related to the remission of symptoms. MATERIALS AND METHODS: This was a prospective cohort study with female patients over 18 years old who underwent surgery for obesity and weight-related diseases between June 2016 and September 2017. Urinary symptoms and quality of life related to UI were assessed based on a structured interview and the results of the validated questionnaires. RESULTS: Two hundred twenty-one patients were assessed pre-operatively, and 118 (53.3%) reported UI. Eighty-eight patients (74.6%) completed the pre- and postoperative questionnaires. After 6 to 12 months, patients were revaluated, and 50 (56.8%) were considered to be in remission of urinary symptoms. Women who had only a cesarean birth had a 117% increase in the probability of achieving remission of UI compared with women who had both vaginal and cesarean deliveries, and patients with an additional point in the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) score at the beginning had a 4% lower probability of having remission of symptoms. CONCLUSIONS: Improvement in UI may be an important outcome of surgery for obesity and weight-related diseases. In this study, previous cesarean section was only associated with the highest rate of remission of symptoms, and patients with higher scores in the ICIQ-UI-SF had a lower probability of remission.

ABSTRACT

Obesity is a prevalent multifactorial chronic disorder characterized by metabolic dysregulation. Sustained pro-oxidative mediators trigger harmful consequences that reflect at systemic level and contribute for the establishment of a premature senescent phenotype associated with macromolecular damage (DNA, protein, and lipids). Telomeres are structures that protect chromosome ends and are associated with a six-protein complex called the shelterin complex and subject to regulation. Under pro-oxidant conditions, telomere attrition and the altered expression of the shelterin proteins are central for the establishment of many pathophysiological conditions such as obesity. Thus, considering that individuals with obesity display a systemic oxidative stress profile that may compromise the telomeres length or its regulation, the aim of this study was to investigate telomere homeostasis in patients with obesity and explore broad/systemic associations with the expression of shelterin genes and the plasma redox state. We performed a cross-sectional study in 39 patients with obesity and 27 eutrophic subjects. Telomere length (T/S ratio) and gene expression of shelterin components were performed in peripheral blood mononuclear cells by qPCR. The oxidative damage (lipid peroxidation and protein carbonylation) and non-enzymatic antioxidant system (total radical-trapping antioxidant potential/reactivity, sulfhydryl and GSH content) were evaluated in plasma. Our results demonstrate that independently of comorbidities, individuals with obesity had significantly shorter telomeres, augmented expression of negative regulators of the shelterin complex, increased lipid peroxidation and higher oxidized protein levels associated with increased non-enzymatic antioxidant defenses. Principal component analysis revealed TRF1 as a major contributor for firstly telomeres shortening. In conclusion, our study is first showing a comprehensive analysis of telomeres in the context of obesity, associated with dysregulation of the shelterin components that was partially explained by TRF1 upregulation that could not be reversed by the observed adaptive non-enzymatic antioxidant response.

ABSTRACT

OBJECTIVE: To analyze the prevalence of urinary incontinence (UI) in female patients with an indication for bariatric surgery, to investigate the potential risk factors and the impact on quality of life. METHODS: A cross-sectional study with female patients with obesity. The evaluation consisted of a structured interview, a specific study form and quality of life questionnaires. The Poisson regression was performed to identify independent risk factors related to UI. RESULTS: A total of 221 patients were enrolled; 118 of the study participants (53.4%) reported UI episodes. Mixed UI (MUI), stress UI (SUI) only, and urgency UI (UUI) only were reported by 52.5% (62), 33.9% (40) , and 13.5% (16) of these patients respectively. The prevalence of UI was increased by 47% among the women who had given birth vaginally and by 34% of the women who had entered menopause. Vaginal delivery and menopause were identified as independent risk factors related to UI. The mean International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) score was 9.36 ± 4.9. The severity of symptoms was considered moderate in 53.3% (63) of the patients with UI. CONCLUSION: Urinary incontinence impacts quality of life negatively, and the prevalence of UI is high among obese patients. In the present study, vaginal delivery and menopause were independently associated with UI.


OBJETIVO: Analisar a prevalência de incontinência urinária (IU), os fatores de risco e o impacto na qualidade de vida em pacientes femininas com indicação para realização de cirurgia bariátrica. MéTODOS: Estudo transversal com pacientes femininas obesas. A avaliação consistiu em entrevista estruturada, com questionários de estudo específico e de qualidade de vida. A regressão de Poisson foi utilizada para identificar os fatores de risco independentes para IU. RESULTADOS: Um total de 221 pacientes foram incluídos; 118 participantes (53.4%) relataram episódios de IU. Incontinência urinária mista, IU de esforço e IU de urgência foram relatadas por 52.5% (62), 33.9% (40) e 13.5%(16) das pacientes, respectivamente. A prevalência de IU foi 47% maior em mulheres que tiveram parto vaginal, e 34% maior em mulheres que já entraram no período da menopausa. Parto vaginal e menopausa foram identificados como fatores de risco independentes para IU.

ABSTRACT

Abstract Objective To analyze the prevalence of urinary incontinence (UI) in female patients with an indication for bariatric surgery, to investigate the potential risk factors and the impact on quality of life. Methods A cross-sectional study with female patients with obesity. The evaluation consisted of a structured interview, a specific study form and quality of life questionnaires. The Poisson regression was performed to identify independent risk factors related to UI. Results A total of 221 patients were enrolled; 118 of the study participants (53.4%) reported UI episodes. Mixed UI (MUI), stress UI (SUI) only, and urgency UI (UUI) only were reported by 52.5% (62), 33.9% (40) , and 13.5% (16) of these patients respectively. The prevalence of UI was increased by 47% among the women who had given birth vaginally and by 34% of the women who had entered menopause. Vaginal delivery and menopause were identified as independent risk factors related to UI. The mean International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) score was 9.36 ± 4.9. The severity of symptoms was considered moderate in 53.3% (63) of the patients with UI. Conclusion Urinary incontinence impacts quality of life negatively, and the prevalence of UI is high among obese patients. In the present study, vaginal delivery and menopause were independently associated with UI.

ABSTRACT

BACKGROUND: The carcinoembryonic antigen level in peritoneal lavage has been showing to be a reliable prognostic factor in gastric cancer. AIM: To identify any association between carcinoembryonic antigen level in peritoneal lavage, in gastric cancer patients, with mortality, peritoneal recurrence, tumor relapse or other prognostic factors. METHODS: In total, 30 patients (22 men, 8 women; median age 66 years) with resectable gastric cancer (mainly stage III and IV) were studied. Carcinoembryonic antigen level in peritoneal lavage was detected at operation by immunocytochemical method and a level over 210 ng/g of protein was considered as positive. RESULTS: There were detected 10 positive cases (33.3%) of plCEA levels. These levels were associated with mortality, RR: 2.1 (p=0.018); peritoneal recurrence, OR: 9.0 (p=0.015); and relapse or gastric cancer progression, OR: 27.0 (p=0.001). CONCLUSION: Increased levels of plCEA fairly predicts mortality, peritoneal recurrence tumor relapse or cancer progression.

ABSTRACT

Resumo A etapa pré-operatória de cirúrgica bariátrica exige que paciente esteja informado sobre as comorbidades associadas à obesidade e dos riscos, benefícios e consequências da cirurgia. O estudo examinou a percepção de risco da cirurgia bariátrica em 128 pacientes, com diferentes comorbidades associadas (doenças cardíacas, diabetes mellitus tipo 2, hipertensão arterial, apneia do sono e dislipidemia) no pré-operatório de cirurgia bariátrica. A percepção de risco da cirurgia e das comorbidades associadas foram avaliadas através de um Questionário de Percepção de Risco. Os pacientes com diabetes mellitus tipo 2, hipertensão arterial e apneia do sono apresentaram avanço mais significativo, em relação as demais comorbidades, para a percepção de risco da cirurgia. Os resultados mostraram que as intervenções educativas expandem a percepção de risco da cirurgia, mas é independente o risco percebido entre as diferentes comorbidades dos pacientes obesos. O estudo aponta a possibilidade de identificar fatores preditivos do comportamento implícito relacionados com a percepção de risco para melhorar o resultado do tratamento a curto e longo prazo, nos pacientes cujas comorbidades são vistas como não oferecendo risco adicional à saúde.


Resumen El preoperatorio de cirugía bariátrica requiere que el paciente sea informado de las comorbilidades asociadas a la obesidad y los riesgos, beneficios y consecuencias de la cirugía. El estudio examinó la percepción de riesgo de la cirugía bariátrica en 128 pacientes con diferentes comorbilidades (enfermedades del corazón, diabetes mellitus tipo 2, hipertensión arterial, apnea del sueño y dislipidemia) en el preoperatorio de la cirugía bariátrica. La percepción de riesgo de la cirugía y las comorbilidades asociadas se evaluó mediante un cuestionario de percepción del riesgo. Los pacientes con diabetes mellitus tipo 2, hipertensión arterial y apnea del sueño tenían avance más significativo, en comparación con otras comorbilidades, a la percepción de riesgo de la cirugía. Los resultados mostraron que las intervenciones educativas ampliar la percepción del riesgo de la cirugía, pero es independiente de la percepción de riesgo entre las diferentes comorbilidades de los pacientes obesos. El estudio apunta a la posibilidad de identificar factores predictivos de comportamiento implícita relacionada con la percepción de riesgo para mejorar el resultado del tratamiento a corto y largo plazo en pacientes cuya comorbilidades son vistos como no proporcionar riesgo para la salud adicional.


Abstract The preoperative stage of bariatric surgery requires that the patient be informed of the obesity-related comorbidities and the risks, benefits, and consequences of surgery. The study examined the preoperative risk perception of bariatric surgery in 128 patients with different comorbidities (heart disease, type 2 diabetes mellitus, hypertension, sleep apnea and dyslipidemia). Risk perception of surgery and associated comorbidities were evaluated using a risk perception questionnaire. Patients with diabetes mellitus type 2, systemic hypertension, and sleep apnea were significantly more likely to perceive the risk of surgery compared to those with the other comorbidities. The results showed that educational interventions expand the risk perception of surgery, but independently of the perceived risk of the different comorbidities of obese patients. The study points to the possibility of identifying predictive factors of behavioral intention related to risk perception to improve short and long-term treatment outcomes in patients whose comorbidities are seen as posing no additional health risk.

RESUMO Racional: Os níveis do antígeno carcinoembriônico no lavado peritoneal têm sido demonstrados como possível fator prognóstico de recidiva e mortalidade em pacientes com câncer gástrico. Objetivos: Medir seus níveis em lavado peritoneal durante operação de ressecção de câncer gástrico e ver se eles aumentados estão relacionados com mortalidade, recorrência, recidiva e outros fatores prognósticos. Métodos: Foi realizado lavado peritoneal durante ressecções de câncer gástrico; os níveis do antígeno carcinoembriônico nesse lavado maiores ou iguais a 210 ng/g foram considerados aumentados ou positivos. Resultados: Foram estudados 30 pacientes, destes, 33,33 % apresentaram níveis aumentados, os quais foram fator de risco para mortalidade em seis meses OR: 8,5 (1,458-49,539) IC 95%, mortalidade geral RR: 2,111 (1,314-3,391) IC 95%, mortalidade devido à doença OR: 12 (1,885-76,376) IC 95%, recorrência peritoneal OR: 9 (1,325-61,138) IC 95%, e recidiva ou progressão da doença OR: 27 (2,705-269,460) IC 95%. Conclusões: Os níveis aumentados do antígeno carcinoembriônico no lavado peritoneal foram fatores de risco para mortalidade, recorrência peritoneal, recidiva e progressão da doença em pacientes com câncer gástrico.

ABSTRACT

OBJECTIVE: To evaluate the consequences of plasma from individuals with obesity on parameters associated with immunosenescence in unrelated healthy peripheral blood mononuclear cells (PBMC). METHODS: Freshly isolated PBMC were incubated in media supplemented with 10% of plasma from individuals with obesity or control subjects for the first 4 hours of 24 to 120 hours of culture. RESULTS: Plasma from individuals with obesity modulated the phenotype of healthy PBMC, leading to a higher rate of apoptosis, lower amounts of phospho-γH2AX and -p53, and mitochondrial dysfunction. After 120 hours, there was a higher secretion of inflammatory cytokines IL-1ß and IL-8. CD8+ T lymphocytes presented decreased expression of CD28, which is associated with the immunosenescent phenotype. CD14+ macrophages showed increased expression of CD80 and CD206, suggesting a modulation in the activation of macrophages. CONCLUSIONS: These results demonstrate that chronic systemic inflammation observed in obesity induces dysfunctional features in PBMC that are consistent with premature immunosenescence.
