Nutritional assessment of servicemen in relation to area of duty and feeding habits: a Pakistani prospective / Avaliação nutricional de militares em relação à área de dever e hábitos alimentares: uma perspectiva paquistanesa

The present study was carried out to determine incidence of overweight and obesity in Pakistani servicemen with reference to their area of duty, feeding habits and also to identify risk factors. Accordingly, 2,501 servicemen selected from all over Pakistan using multiple stage stratified sampling protocol. Nutrition assessment performed using body mass index (BMI), waist to hip ratio (WHR) and dietary assessment using food frequency questionnaire. Collected data was analyzed using the SPSS version 25. Regression was used to find risk factors of obesity and WHR. Results indicated that about 1/4th of servicemen were smokers. Approximately, 1/5th of them were overweight and about one quarter were eating fruits and vegetables for <3 days/ week and <4 days/week, respectively. Only 1/3rd of them were physically active for at least <40 minutes per day. Age and fruits intake were significantly predicting BMI with a direct relation and vegetable intake was negatively correlated to BMI of the servicemen. Age and rank were significant predictors of WHR while, physical activity was negatively correlated to WHR. It is concluded and suggested from our study that there is a need to modify eating patterns and habits as well as improving physical activity on daily basis for healthy and long life of the servicemen.

O presente estudo foi realizado para determinar a incidência de sobrepeso e obesidade em militares paquistaneses com referência à sua área de serviço, hábitos alimentares e também para identificar fatores de risco. Assim, 2.501 militares selecionados de todo o Paquistão usando protocolo de amostragem estratificada de múltiplos estágios. Avaliação nutricional realizada por meio do índice de massa corporal (IMC), relação cintura-quadril (RCQ) e avaliação alimentar por meio de questionário de frequência alimentar. Os dados coletados foram analisados por meio do SPSS versão 25. A regressão foi usada para encontrar fatores de risco para obesidade e RCQ. Os resultados indicaram que cerca de 1/4 dos militares eram fumantes. Aproximadamente, 1/5 deles estava com sobrepeso e cerca de um quarto comia frutas e vegetais por <3 dias / semana e <4 dias / semana, respectivamente. Apenas 1/3 deles era fisicamente ativo por pelo menos <40 minutos por dia. Idade e ingestão de frutas foram preditores significativos do IMC com uma relação direta e ingestão de vegetais foi negativamente correlacionada com o IMC dos militares. Idade e posição foram preditores significativos de RCQ, enquanto a atividade física foi negativamente correlacionada com RCQ. Conclui-se e sugere-se a partir de nosso estudo que há necessidade de modificar os padrões e hábitos alimentares, bem como melhorar a atividade física no dia a dia para uma vida longa e saudável dos militares.

Study on related factors and characteristics of multimorbidity of overweight and obesity-related diseases in children in Hunan Province / 中华预防医学杂志

From January 2019 to December 2021, overweight and obese children who visited in health outpatient Center of Hunan Children's Hospital were studied to explore and analyze the rate, related factors and patterns of multimorbidity of overweight and obesity-related diseases in children in Hunan Province. Univariate and multivariate logistic regression models were used to analyze the multimorbidity-related factors of overweight and obesity-related diseases in children. Association rules (apriori algorithm) were used to explore the multimorbidity patterns of overweight and obesity-related diseases in children. A total of 725 overweight and obese children were included in this study. The multimorbidity rate of overweight and obesity-related diseases in children was 46.07% (334/725). Age, waist circumference, the frequency of food consumption such as hamburgers and fries and adding meals before bedtime were multimorbidity-related factors of overweight and obesity-related diseases in children. The multimorbidity associated with nonalcoholic fatty liver disease (NAFLD) was relatively common. The patterns with the top three support degrees were "NAFLD+dyslipidemia","NAFLD+hypertension" and "NAFLD+hyperuricemia". The patterns with the top three confidence and elevation degrees were "Hypertension+dyslipidemia => NAFLD","Hyperuricemia => NAFLD" and "NAFLD+hypertension => dyslipidemia".

Sex- and age-specific impacts of smoking, overweight/obesity, hypertension, and diabetes mellitus in the development of disabling dementia in a Japanese population

BACKGROUND@#Sex- and age-specific impacts of cardiovascular risk factors on the development of dementia have not been well evaluated. We investigated these impacts of smoking, overweight/obesity, hypertension, and diabetes mellitus on the risk of disabling dementia.@*METHODS@#The study participants were 25,029 (10,134 men and 14,895 women) Japanese aged 40-74 years without disabling dementia at baseline (2008-2013). They were assessed on smoking status (non-current or current), overweight/obesity (body mass index ≥25 kg/m2 and ≥30 kg/m2, respectively), hypertension (systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg or any antihypertensive medication use), and diabetes mellitus (a fasting serum glucose ≥126 mg/dL, non-fasting glucose ≥200 mg/dL, hemoglobin A1c ≥6.5% by the National Glycohemoglobin Standardization Program or glucose-lowering medication use) at baseline. Disabling dementia was identified as the level of care required ≥1 and cognitive disability grade ≥IIa according to the National Long-term Care Insurance Database. We used a Cox proportional regression model to estimate hazard ratios and 95% confidence intervals (95% CIs) of disabling dementia according to the cardiovascular risk factors and calculated the population attributable fractions (PAFs).@*RESULTS@#During a median follow-up of 9.1 years, 1,322 (606 men and 716 women) developed disabling dementia. Current smoking and hypertension were associated with a higher risk of disabling dementia in both sexes, whereas overweight or obesity was not associated with the risk in either sex. Diabetes mellitus was associated with a higher risk only in women (p for sex interaction = 0.04). The significant PAFs were 13% for smoking and 14% for hypertension in men and 3% for smoking, 12% for hypertension, and 5% for diabetes mellitus in women. The total PAFs of the significant risk factors were 28% in men and 20% in women. When stratified by age, hypertension in midlife (40-64 years) was associated with the increased risk in men, while diabetes mellitus in later-life (65-74 years) was so in women.@*CONCLUSIONS@#A substantial burden of disabling dementia was attributable to smoking, and hypertension in both sexes and diabetes mellitus in women, which may require the management of these cardiovascular risk factors to prevent dementia.

Study on the relationship between indexes of different abnormal weight and dyslipidemia in adults in Beijing City / 中华预防医学杂志

Objective: To analyze the relationship and consistency between indexes of different abnormal weight and dyslipidemia in adults in Beijing City. Methods: From August to December of 2017, 4 975 residents aged 18 to 79 years old in 5 districts of Beijing were randomly selected as subjects by using a multi-stage stratified cluster sampling method. Questionnaire, physical examination and laboratory tests were conducted. The prevalence of overweight/obesity, high body fat rate, central obesity, and high waist-to-height ratio was calculated. Partial correlation was used to analyze the correlation of blood lipid with body mass index (BMI), body fat rate, waist circumference and waist-height ratio. Logistic regression analysis for complex sampling was used to analyze the relationship between indexes of different abnormal weight and dyslipidemia after controlling for relevant risk factors, including age, sex, smoking status, drinking, insufficiency intake of vegetable and fruit, physical inactivity. Kappa value was computed to analyze the consistency between indexes of different abnormal weight. Results: The weighted prevalence of dyslipidemia was 30.48%, and it was higher in men than that in women (40.16% vs. 20.52%, P<0.01). The weighted rate of overweight/obesity, high body fat rate, central obesity, and high waist-to-height ratio was 56.65%, 47.52%, 42.48% and 59.45%, respectively. BMI, body fat rate, waist circumference and waist-to-height ratio were positively correlated with the level of total cholesterol, triglyceride, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol, and negatively correlated with high-density lipoprotein cholesterol. Logistic regression analysis for complex sampling showed that the high body fat rate (OR=1.67, 95%CI: 1.35-2.07), overweight/obesity (OR=1.65, 95%CI: 1.26-2.14) and high waist-to-height ratio (OR=1.46, 95%CI: 1.09-1.96) were associated with dyslipidemias. Kappa values of high body fat rate with overweight/obesity, high waist-to-height ratio and central obesity were 0.65, 0.53 and 0.58, respectively (P<0.05). Conclusion: In 2017, the prevalence of dyslipidemia in adults in Beijing City is high, especially in men. Overweight/obesity, high body fat rate and high waist-to-height ratio are associated with dyslipidemia. The high body fat rate is most associated with dyslipidemia.

A pre-conception cohort study of fertility and its related factors among couples with the intention of conception / 中华预防医学杂志

Objective: To describe fertility and explore factors associated with it among pre-conception couples of childbearing age. Methods: Based on the pre-conceptional offspring trajectory study of the School of Public Health of Fudan University, couples of childbearing age who participated in the pre-conception physical examination in Shanghai Jiading District from 2016 to 2021 were recruited and followed up. Couples' time to pregnancy (TTP) was analyzed and Cox proportional hazards regression model was used to explore the factors associated with TTP. Kaplan-Meier was used to calculate each menstrual cycle's cumulative pregnancy rate. Results: A total of 1 095 preconception couples were included in the analysis, the M(Q1,Q3)of TTP was 4.33 (2.41, 9.78) menstrual cycles. Age of women (FR=0.90, 95%CI: 0.85-0.95, P<0.001), women who were overweight or obese before pregnancy (FR=0.36, 95%CI: 0.24-0.55, P<0.001), women who were exposed to second-hand smoking (FR=0.63, 95%CI: 0.44-0.92, P=0.016), women whose home or office had been renovated in the past 2 years and had a particular smell (FR=0.46, 95%CI: 0.26-0.81, P=0.008) were risk factors for impaired fertility. Regular menstrual cycles (FR=1.64, 95%CI: 1.16-2.31, P=0.005), females who often drank tea/coffee (FR=1.55, 95%CI: 1.11-2.17, P=0.011) and males who took folic acid before conception (FR=2.35, 95%CI: 1.38-4.23, P=0.002) were associated with better fertility. The cumulative pregnancy rate of 3, 6, and 12 menstrual cycles was 37.6%, 64.4%, and 78.4%, respectively. Conclusion: Older couples, overweight or obesity before pregnancy, irregular menstruation, exposure to secondhand smoke and decoration pollutants in females are associated with impaired fertility. Frequent tea/coffee drinking before pregnancy in females and taking folic acid before pregnancy in males are associated with shortened conception time.

A cross-sectional study on the prevalence rate and influencing factors of non-alcoholic fatty liver disease in overweight/obese children / 中国当代儿科杂志

OBJECTIVES@#To investigate the prevalence rate of non-alcoholic fatty liver disease (NAFLD) in overweight/obese children who visit a hospital, and to explore the influencing factors of NAFLD, in order to provide a basis for the prevention of NAFLD in overweight/obese children.@*METHODS@#Overweight/obese children who visited Hunan Children's Hospital from June 2019 to September 2021 were recruited. The prevalence rate of NAFLD was examined. Logistic regression analysis was used to explore the factors influencing the development of NAFLD [non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH)]. Receiver operating characteristic curve analysis was used to evaluate the predictive value of the influencing factors for NAFL and NASH.@*RESULTS@#A total of 844 overweight/obese children aged 6-17 years were enrolled. The prevalence rate of NAFLD in overweight/obese children was 38.2% (322/844), among which the prevalence rates of NAFL and NASH were 28.8% (243/844) and 9.4% (79/844), respectively. Multivariate logistic regression analysis showed that the increase of waist-to-hip ratio (WHR) and low high-density lipoprotein cholesterol (HDL-C) were associated with the development of NAFL and NASH (P<0.05). The receiver operating characteristic curve analysis showed that the combined measurement of WHR and HDL-C had a predictive value for NAFL (area under the curve: 0.653, 95%CI: 0.613-0.694), and for NASH (area under the curve: 0.771, 95%CI: 0.723-0.819).@*CONCLUSIONS@#The prevalence rate of NAFLD in overweight/obese children who visit a hospital is high. WHR and HDL-C are associated with the development of NAFLD and the combined measurement of WHR and HDL-C has a certain value for predicating the development of NAFLD.

Malnutrición por exceso durante la gestación: análisis de tendencia secular y de factores asociados, Región de La Araucanía, Chile / Secular trend for overweight and excessive weight gain during pregnancy in a Southern Chilean region

BACKGROUND: Overweight during pregnancy has increased in Chile. In the region of La Araucanía it occurs in 67% of pregnancies, which exceeds the national indicators. AIM: To analyze the secular trend during eight years of the nutritional status at the beginning of gestation, the excessive weight gain during pregnancy, and its association with individual factors in pregnant women cared the public health system of two Southern Chilean neighboring cities. MATERIAL AND METHODS: This is an analytical observational study with a cross-sectional and longitudinal trend design. We used an anonymized database with 17,270 reproductive data of urban pregnant women who were cared between 2009 and 2016. Trend analysis was performed to evaluate secular changes (nptrend < 0.05) in nutritional indicators and logistic regression to determine the association with individual characteristics. RESULTS: In the study period, overweight at the beginning of pregnancy increased by 13.1 percentage points. Forty percent of pregnant women with normal initial body mass index, were overweight or obese at the end of pregnancy. The excessive weight gain decreased slightly (z=-3.33, p = 0.001), but unevenly in both cities. Adolescent pregnancy, a low education and low socio-economic level of household together with previous overweight and a family or personal history of chronic diseases are associated with excessive gestational weight gain. Conclusions: The results show social inequality. Female malnutrition by excess is a problem that must be addressed through a robust public policy, centered on primary health care level and with a focus on social determinants. Prenatal care provides a window of opportunity to intervene.

Overweight/obesity in adolescents with phenylketonuria: protective and predisposing factors

Abstract Objective: To estimate the prevalence and factors associated with overweight/obesity development in adolescents with early diagnosed phenylketonuria treated exclusively by diet. Methodology: In this cross-sectional study anthropometric measurements, serum phenylalanine levels, and 10 metabolites associated with lipid and carbohydrate metabolism were analyzed in 101 adolescents aged 10-20 years. Adolescents were categorized into overweight/obesity and eutrophic/low body mass index groups. These patients were compared using Student's t-test, Pearson's chi-square test, Wald's chi-square test for multivariate analysis. Further, to verify whether the prevalence of overweight/obesity found in the study population was similar to that in the general population, the authors compared the nutritional status of 46 patients aged 13-17 years with that of healthy students of the same age from the National School Health Survey using the chi-square test for adherence. The significance threshold was p < 0.5. Results: The prevalence of overweight/obesity in adolescents was 27.7%. There was no difference in prevalence between sexes. Older age was a protective factor and Increased Homeostasis Model Assessment Insulin Resistance index and high phenylalanine and low-density lipoprotein cholesterol levels were predictive factors for overweight/obesity. The equality hypothesis was not rejected in the comparison of nutritional states of 46 patients aged 13-17 years and healthy students of the same age. Conclusion: The prevalence of overweight/obesity in phenylketonuria adolescents was similar to what is found in healthy adolescents.

Association of Overweight and Consistent Anovulation among Infertile Women with Regular Menstrual Cycle: A Case-control Study / Associação entre sobrepeso e anovulação consistente em mulheres inférteis com ciclo menstrual regular: Um estudo de caso-controle

Abstract Objective It has been suggested that excess body weight could represent a risk factor for infertility outcomes. The present study aimed to evaluate the association of overweight and anovulation among infertile women with regular menstrual cycles. Methods We conducted a retrospective case-control study with consistently anovulatory patients undergoing assisted reproduction treatment. The patients were stratified into normal weight (body mass index [BMI]: 18.5-24.9kg/m2) and overweight (BMI: 25.0- 29.9kg/m2).Those with polycystic ovary syndrome or obesity were excluded. The groups were matched for age, duration of infertility, prolactin, follicle stimulating hormone (FSH), thydroid stimulating hormone (TSH), luteinizing hormone (LH), and estradiol levels. Results Overweight was significantly associated with anovulation, when using the World Health Organization (WHO) criteria for anovulation: progesterone levels>5.65 ng/ml and ultrasonography evidence of follicle collapse (odds ratio [OR]: 2.69; 95% confidence interval [CI95%]: 1.04-6.98). Conclusion Body mass index above the normal range jeopardizes ovulation among non-obese infertile women with regular menstrual cycles.

Introducción: El sobrepeso y la obesidad son considerados por la Organización Mundial de la Salud como un factor de riesgo metabólico asociado a enfermedades no transmisibles. Objetivo: Evaluar la asociación entre sobrepeso y obesidad con los antecedentes de colesterol sanguíneo elevado, presión arterial alta y diabetes sacarina. Métodos: Estudio transversal, analítico, realizado en 297 estudiantes de una universidad privada de Panamá. Se consideró como variable dependiente el sobrepeso-obesidad determinada para los participantes con un IMC ≥ 25 kg/m2. Para establecer los antecedentes de presión arterial alta, diabetes sacarina y colesterol sanguíneo elevado, se aplicó el cuestionario básico del instrumento STEPS de la Organización Mundial de la Salud. Fueron realizados análisis descriptivos, bivariados y múltiples utilizando modelos de regresión logística. Resultados: El 46,12 por ciento de la población de estudio presentó sobrepeso-obesidad. Los hombres mostraron una prevalencia estadísticamente significativa más alta que las mujeres. El 12,45 por ciento, 11,11 por ciento y 8,75 por ciento de los estudiantes reportaron antecedente de presión arterial alta, colesterol sanguíneo elevado y diabetes sacarina, respectivamente. Después de ajustar por sexo, edad y nivel socioeconómico, los participantes que reportaron antecedente de colesterol sanguíneo elevado en sangre presentaron una mayor probabilidad de tener sobrepeso-obesidad (OR = 2,92, IC 95 por ciento: 1,07-7,93, p = 0,035). Conclusiones: Casi la mitad de los universitarios presentaron sobrepeso-obesidad. Se encontró una mayor probabilidad de tener sobrepeso-obesidad en los estudiantes que reportaron colesterol sanguíneo elevado.

Introduction: To the World Health Organization, overweight and obesity are metabolic risk factors for non-communicable diseases. Objective: Evaluate the association of overweight and obesity to a history of high blood cholesterol, high arterial pressure and diabetes mellitus. Methods: An analytical cross-sectional study was conducted of 297 students from a private university in Panama. Overweight-obesity was considered as a dependent variable determined for participants with a BMI ≥ 25 kg/m2. High arterial pressure, diabetes mellitus and high blood cholesterol antecedents were established with the basic questionnaire in the STEPS World Health Organization tool. Descriptive, bivariate and multiple analyses were performed with the use of logistic regression models. Results: 46.12 percent of the study population were overweight-obese. Statistically significant prevalence was higher in men than in women. 12.45 percent, 11.11 percent and 8.75 percent of the students surveyed reported a history of high arterial pressure, high blood cholesterol and diabetes mellitus, respectively. After adjustment for sex, age and socioeconomic level, participants reporting a history of high blood cholesterol had a greater probability of being overweight-obese (OR = 2.92, CI 95 percent: 1.07-7.93, p = 0.035). Conclusions: Almost half of the university students were overweight-obese. A higher probability of being overweight-obese was found in students reporting high blood cholesterol. It is necessary to implement strategies fostering the acquisition of healthy living habits by the Panamanian university population, thus reducing future cardiovascular risk(AU)

Are overweight and obesity risk factors for invasive mechanical ventilation in severe coronavirus disease 2019 pneumonia?

ABSTRACT Objective: Describe the demographic, clinical, and biochemical characteristics of overweight or obese people with severe COVID-19 pneumonia and evaluate its association with mechanical ventilation requirements in a Mexican cohort. Subjects and methods: Data were obtained from medical electronic records. Patients were divided in three groups according to the World Health Organization (WHO) classification of body mass index (BMI): lean, overweight and obese. Baseline characteristics and clinical course were compared among these 3 groups. Results: The study included a total of 355 patients with confirmed COVID-19 diagnoses. Patients with obesity and overweigh, according to the WHO classification, had no significantly increased risk of requiring intubation and invasive mechanical ventilation (IMV) compared to lean subjects, with an odds ratio (OR) of 1.82 (95% CI, 0.94-3.53). A post hoc and multivariate analysis using a BMI > 35 kg/m2 to define obesity revealed that subjects above this cut off had as significantly increased risk of requiring IMV after with an OR of 2.86 (95% CI, 1.09-7.05). Conclusion: We found no higher risk of requiring IMV in patients with overweight or obesity while using conventional BMI cutoffs. According to our sensitivity analyses, the risk of IMV increases in patients with a BMI over 35 kg/m2.

Indice de masa corporal como factor de riesgo que afecta a la osteoartritis de rodilla de los ancianos / Body Mass Index as the Risk Factor Affecting Knee Osteoarthritis of the Elderly

Introducción: La osteoartritis es una enfermedad que progresa con el tiempo y culmina en la destrucción de articulaciones y ligaduras. La Investigación Básica de Salud (RISKESDAS) 2013 muestra que East Nusa Tenggara tiene la prevalencia más alta de la enfermedad reumática en Indonesia, alrededor del 33,1%. Método: Esta investigación es un estudio observacional-analítico con un diseño transversal. Esta investigación tiene como objetivo determinar los factores que afectan la osteoartritis de los ancianos en el Centro de Salud Comunitario de Sikumana, distrito de Maulafa, ciudad de Kupang durante el período de diciembre de 2018 a febrero de 2019. Resultado: En esta investigación, índice de masa corporal / IMC (PR = 1,21, p = 0,037) tiene una correlación significativa con la osteoartritis de los ancianos, sin embargo, el género (RP = 1,02, p = 0,839) y los antecedentes de trauma de rodilla (RP = 1,08, p = 0,453) no tienen una correlación significativa con la osteoartritis de los ancianos. Conclusión: un cuerpo con sobrepeso aumenta la presión mecánica de la articulación de la rodilla, lo que provoca la osteoartritis. En esta investigación, las mujeres tienen un mayor riesgo de sufrir osteoartritis en comparación con los hombres. Cuanto mayor sea el IMC, la prevalencia de la osteoartritis aumenta significativamente. Alrededor del 41% de los ancianos con osteoartritis tienen obesidad. Entre otros riesgos, la obesidad muestra una correlación con la prevalencia de osteoartritis. Se debe aumentar la conciencia de los pacientes sobre el índice de masa corporal (IMC) para reducir la prevalencia de la osteoartritis.

Method: This research is an observational-analytic study with a cross-sectional design. This research aims to determine the factors affecting Osteoarthritis of the Elderly at Sikumana Community Health Center, Maulafa District, Kupang City during the period of December 2018 to February 2019. Result: In this research, body mass index/BMI (PR=1,21, p=0,037) has a significant correlation to osteoarthritis of the elderly, yet gender (PR=1,02, p=0,839) and history of knee trauma (PR=1,08, p=0,453) have no significant correlation to osteoarthritis of the elderly. Conclusion: An overweight body increases the mechanical pressure of the knee joint, which causes osteoarthritis. In this research, women have a higher risk of osteoarthritis compared to men. The higher the BMI, the prevalence of osteoarthritis increases significantly. Around 41 % of the Elderly with Osteoarthritis have obesity. Amongst any other risks, obesity shows a correlation with the prevalence of Osteoarthritis. Patients' awareness of the body mass index (BMI) should be increased to reduce the prevalence of osteoarthritis.

The association between body mass index and varicocele: A meta-analysis

ABSTRACT Objective: Recently, several studies have found that obesity had a protective effect against varicocele, but no meta-analysis has confirmed this finding. Therefore, we conducted this meta-analysis to investigate the association between body mass index (BMI) and varicocele. Material and Methods: We searched for studies in PubMed, Science Direct and the Cochrane Library from inception until February 2018. The association between BMI and varicocele was assessed by pooling the odds ratios (ORs). Results: Eleven eligible studies with a total study population of 1.376.658 participants were included in our analysis. According to BMI, the subjects were defined as belonging to the obese, overweight and underweight groups. Our results showed that the obese group had a lower risk of varicocele when compared with the normal weight group (odds ratio [OR] 0.46, 95% confidence intervals [CIs] 0.37-0.58). Additionally, an overweight BMI had a protective effect against varicocele (OR 0.70, 95% CIs, 0.56-0.86). However, underweight patients had a more than 30% higher risk of varicocele (OR 1.31, 95% CI, 1.04-1.64). Furthermore, there was no publication bias in any of the analyses. Conclusions: Our study demonstrates that BMI is negatively associated with the presence of varicocele.

Efficacy comparison of robotic and laparoscopic radical resection of rectal cancer for overweight and obese patients / 中华胃肠外科杂志

Objective: During laparoscopic pelvic operational procedure for obese patients with rectal cancer, the large amount of fat in the abdominal cavity often impairs the exposure of the surgical field, resulting in technical difficulty. In contrast, robotic surgery has the advantages of being more minimally invasive, precise, and flexible. This study compared the clinical efficacy of robotic and laparoscopic radical resection of rectal cancer for overweight and obese patients. Methods: A retrospective cohort study was conducted. Clinical data of 173 patients with rectal cancer and a body mass index (BMI) ≥ 25 kg/m(2) who received robotic or laparoscopic radical rectal resection at the First Affiliated Hospital of Nanchang University from January 2015 to February 2019 were retrospectively collected. Of 173 patients, 90 underwent robotic surgery and 83 underwent laparoscopic surgery. The intraoperative parameters, postoperative short-term and follow-up status were analyzed and compared between the two groups. The follow-up ended in December 2019. Results: Of 173 patients, 103 were male and 70 were female with a median age of 62 (range 29 to 86) years. The average BMI was (27.2±1.6) kg/m(2) in the robotic group and (27.3±1.5) kg/m(2) in the laparoscopic group. No significant differences in baseline data were observed between two groups (all P>0.05). As compared to the laparoscopic group, the robotic group had less intraoperative blood loss [(73.0±46.8) ml vs. (120.9±59.9) ml, t=-5.881, P<0.001] and higher postoperative hospitalization expense [(61±15) thousand yuan vs (52±13) thousand yuan, t=3.468, P=0.026]. The conversion rate in the robotic group was 1.1% (1/90), which was lower than 6.0% (5/83) in the laparoscopic group, but the difference was not statistically significant (P=0.106). There were no statistically significant differences between the two groups in operative time, number of intraoperative blood transfusion, number of harvested lymph nodes, time to the first flatus, postoperative hospital stay and morbidity of total postoperative complications (all P>0.05). Five (6.0%) patients in the laparoscopic group developed urinary dysfunction, while no case in the robotic group developed postoperative urinary dysfunction (P=0.024). The 173 patients were followed up for 8-59 months, with a median follow-up of 36 months. The 3-year overall survival rate of robotic group and laparoscopic group was 89.8% and 86.6%, respectively without significant difference between the two groups (P=0.638). The 3-year disease-free survival rate of the robotic group and the laparoscopic group was 85.6% and 81.5%, respectively without significant difference as well (P=0.638). Conclusions: Robotic radical surgery is safe and feasible for overweight and obese patients with rectal cancer. Compared with laparoscopic radical surgery, it has advantages of clear vision of surgical exposure, less intraoperative blood loss, less pelvic autonomic nerve damage, and operation in a narrow space.

Body mass index is associated with low postoperative cardiac output in patients undergoing aortic valve replacement / El índice de masa corporal se asocia a bajo gasto cardiaco postoperatorio de pacientes sometidos a reemplazo valvular aórtico

Abstract Background: Overweight and obesity (O/O) generate lipotoxicity of the cardiac fiber and increase the incidence and progression of aortic valve stenosis. The low cardiac output syndrome (LCOS) is a timing complication after to aortic valve replacement (AVR) surgery. Objective: The objective of the study was to investigate if body mass index (BMI) kg/m2 is a risk factor associated with LCOS and mortality in the post-operative period of AVR. Methods: A historic cohort study was designed, including patients with severe aortic stenosis (SAS), who were subjected to AVR. Results: 152 patients were included, 45 (29.6%), with normal weight (NW), 60 were overweight (39.5%), and 47 obese (30.9%). The prevalence of systemic hypertension (HT) was higher in O/O (p < 0.0001). Incidence of LCOS was 44.7%, being more frequent in the O/O groups compared to the NW group, 43.3%, 68.1%, and 22.2%, respectively, (p < 0.05 in overweight and p < 0.0001 in the obese). Assessing the presence or absence of LCOS associated with BMI as a numerical variable, we found that women, HT, BMI, left ventricular mass, and valve size, were associated with LCOS (p < 0.02, p < 0.02, p < 0.001, p < 0.032, and p < 0.045, respectively). Mortality was higher in patients who had LCOS (p < 0.02). Multivariate model showed that BMI was an independent risk factor for LCOS (odds ratio [OR] 1.21 [95% CI 1.08-1.35], p < 0.001). Conclusion: BMI is a risk factor associated to LCOS in the post-operative period of AVR in patients with SAS.

Resumen Antecedentes: El sobrepeso y la obesidad (O/O) generan lipotoxicidad de la fibra cardíaca y aumentan la incidencia y progresión de la estenosis de la válvula aórtica. El síndrome de bajo gasto cardíaco (SBGC) es una complicación postquirúrgica de la cirugía de reemplazo de válvula aórtica (RVA). Objetivo: Investigar si el índice de masa corporal kg/m2 (IMC) es un factor de riesgo asociado con SBGC y mortalidad en el postoperatorio de RVA. Métodos: Se diseñó un estudio de cohorte histórico, que incluyó pacientes con estenosis aórtica importante (EAI), que fueron sometidos a RVA. Resultados: Se incluyeron 152 pacientes, 45 (29.6%), con peso normal (N), 60 tenían sobrepeso (39.5%) y 47 obesos (30.9%). La prevalencia de hipertensión sistémica (HT) fue mayor en O/O (p < 0.0001). La incidencia de SBGC fue del 44.7%, siendo más frecuente en los grupos O/O en comparación con el grupo N, 43.3%, 68.1%, 22.2% respectivamente, (p < 0.05 en sobrepeso y p < 0.0001 en obesos). Al evaluar la presencia o ausencia de SBGC asociado con el IMC como una variable numérica, encontramos que las mujeres, HT, IMC, masa ventricular izquierda y tamaño de la válvula, se asociaron con SBGC (p < 0.02, p < 0.02, p < 0.001, p < 0.032, p < 0.045, respectivamente). La mortalidad fue mayor en pacientes con SBGC (p < 0.02). El modelo multivariado mostró que el IMC fue un factor de riesgo independiente asociado a SBGC [OR 1.21 (IC 95% 1.08-1.35), p < 0.001]. Conclusión: El IMC es un factor de riesgo asociado a SBGC en el postoperatorio de RVA en pacientes con EAI.

A influência do sobrepeso/ obesidade sobre o uso do levonorgestrel como método contraceptivo de emergência / The influence of overweight/obesity over the use of levonorgestrel as an emergency contraceptive method

A contracepção de emergência tem como objetivo prevenir uma gravidez indesejada após uma relação sexual desprotegida, falha do método contraceptivo regular ou agressão sexual. Dentre os métodos disponíveis atualmente, destaca-se a pílula hormonal de levonorgestrel (LNG) como uma das principais estratégias utilizadas, tendo em vista o perfil de segurança desse fármaco e a facilidade de acesso e utilização dele. No entanto, embora o efeito de tal molécula seja satisfatório, pesquisas sugerem que altos índices de massa corporal implicam uma redução da eficácia contraceptiva da pílula de LNG. Nesse sentido, esse estudo visa evidenciar, mediante revisão de literatura, a relação entre esse fármaco e sua competência em mulheres com sobrepeso ou obesidade, bem como expor quais medidas devem ser tomadas para evitar a gravidez indesejada nessas pacientes. Embora existam divergências, foi observado que a maior parte dos estudos indica que a composição corporal das pacientes pode influenciar na eficácia contraceptiva da molécula de LNG, de forma sinérgica ou não com outros fatores, especialmente quando considerado o IMC > 25 kg/m² ou peso > 75 kg, uma vez que o risco de gravidez pode aumentar de 1,5 até 4,4 vezes quando comparado aos padrões de normalidade, com tendência de crescimento em relação aos parâmetros de sobrepeso/obesidade.(AU)

The main goal of the emergency contraceptive is to prevent a non-planned pregnancy after the sexual relationship without condom, after the fail of the usual contraceptive or the sexual assault. Among all the currently available methods, the hormonal pill of levonorgestrel (LNG) has its importance as one of the most used strategies, due of its safety, easy access and use. However, in spite of the fact that this molecule has a good effect, some researches suggest that a high level of the body mass reduces the efficacy of the contraceptive pill of LNG. In this context, this study objective is to clarify, by using literature review, the relation between this drug and its competence in overweight/obese women, as well to expose which other options could be taken to avoid a non-planned pregnancy in those patients. Despite of the fact that there are divergences, the most part of the studies shows that patient's body composition can influence on the contraceptive effectiveness of the LNG molecule, sinergically or not to other factors, especially when the IMC > 25 kg/m² or the body weight > 75 kg, once the pregnancy risk can be raised from 1,5 to 4,4 times when compared to regular standards, with growth tendency when related to overweigh/obesity parameters.(AU)
