Excess adiposity and iron-deficient status in Colombian women of reproductive age.

OBJECTIVE: Information about excess adiposity markers different from BMI and iron status is limited and more so about the shape of these associations. This study evaluated the relationship between three adiposity markers and iron-deficient status in reproductive-age women. METHODS: Cross-sectional analysis in 6357 non-pregnant women from the Colombian nutritional health survey (ENSIN) 2010. Exposures were the following: waist circumference (WC), waist-to-height ratio (W-HtR), BMI, and WC > 80 cm, W-HtR > 0.5, and BMI ≥ 25 and ≥30. Outcomes were the following: iron deficiency (ID) as serum ferritin <15 µg/L, ID as ferritin <30 µg/L, anemia, and continuous values of ferritin and hemoglobin. Logistic and linear regressions adjusted for sociodemographic/inflammation covariates were conducted. RESULTS: All the adiposity markers, continuous or categorical, were inversely and significantly associated with both ID thresholds in fully adjusted models (p < 0.05). W-HtR reported stronger effect estimates for ID (odds ratios < 0.5) and for prediction of log-ferritin levels (fully adjusted ß-coefficient [95% CI] 0.61 [0.39-0.82], p < 0.01) and was also inversely associated with anemia (p < 0.05). In cubic splines analyses, W-HtR, WC, and BMI were linearly associated with ID from values closer to international thresholds of general or central obesity, and the patterns of WC and BMI tended toward flatness. A significant decline in the likelihood of anemia was steeper by increasing W-HtR than by increasing BMI. After exclusion of women with C reactive protein > 5 mg/L or adjustment for C reactive protein, adiposity markers remained significantly related to ferritin levels and W-HtR with anemia. CONCLUSIONS: Women with higher adiposity were less likely to have an iron-deficient status. W-HtR was the strongest and most consistently associated marker. Inflammation would not be involved in the associations found.

Factors associated with different patterns of weight change after bariatric surgery: A longitudinal study.

Background: The mean weight loss (WL) after successful bariatric surgery is approximately one third of the initial body weight, which is mainly achieved between the first 2 years of follow-up. However, 15%-35% of patients do not achieve a significant percentage of total WL (%TWL). Information on factors associated with a higher or lower WL after bariatric surgery is limited. This study aimed to assess the change in %TWL and describe the factors associated with greater or lesser WL over time. Methods: This prospective longitudinal study included patients treated with laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy. Baseline data were recorded before surgery. Follow-up was performed at 3 (n = 141), 6 (n = 208), 9 (n = 115), 12 (n = 216), 24 (n = 166), and 36 months (n = 99). Generalized estimating equation analysis was performed to assess the changes in %TWL over time and factors associated with different patterns of WL. Results: In total, 231 patients were included (women, 82.2%; basal body mass index (BMI) 41.4 ± 5.1 kg/m2). The tendencies to increase %TWL (32 ± 6.5) were evident in the first year and stabilized thereafter. Sustained nutritionist follow-up (2.3%, p = 0.004), baseline BMI >40 kg/m2 (0.4%, p < 0.001), and WL ≥ 10 kg before surgery (0.3%, p = 0.001) were associated with a higher %TWL. Patients who performed physical activity >30 min/day after surgery reduced their %TWL by 0.6% (p = 0.002). Conclusions: Modifiable factors such as nutritional monitoring and WL before surgery are associated with a significant increase in %TWL over time. Basal BMI was associated with a significant decrease in %TWL.

Comparación entre mediciones e índices antropométricos para evaluar la obesidad general y la abdominal, Colombia ENSIN 2015

Introducción. El exceso de peso representa un problema en la población adulta, el cual aumentó en los últimos años y se asocia con enfermedades no transmisibles. Objetivos. Comparar las mediciones con los índices antropométricos y evaluar su relación con variables individuales y sociodemográficas para generar información sobre el uso de las principales medidas en la evaluación de la obesidad general y la abdominal como indicadores de riesgo cardiovascular. Materiales y métodos. Se hace un análisis secundario de la encuesta ENSIN para Colombia, con datos recolectados entre el 2015 y el 2016. Como marco muestral, se utilizó el Censo de Población y Vivienda del 2005 del Departamento Administrativo Nacional de Estadística (DANE), y la muestra incluyó 44.202 hogares y 151.343 personas de 0 a 64 años; para este análisis, se seleccionaron 70.315 registros de población adulta. Se calcularon proporciones, intervalos de confianza, medidas de tendencia central y dispersión. Resultados. Las medias del índice de masa corporal (IMC) y del índice cintura-estatura fueron más grandes que el punto de corte en ambos sexos, mientras que las medias de la circunferencia de la cintura estuvieron por debajo del corte para los hombres y por encima de aquel para las mujeres (p<0,05). La prevalencia de obesidad por IMC fue de 17,5 %, mientras que la obesidad abdominal, según la circunferencia de la cintura, fue de 50,2 %, y según el índice cintura-estatura, de 62,6 %. Conclusiones. Independientemente del indicador utilizado, la obesidad abdominal es cerca de tres veces más frecuente que la obesidad general por IMC; con el índice cintura- estatura se identifican más personas, en especial hombres, con obesidad abdominal en comparación con la circunferencia de la cintura.

Introduction. Excess weight represents a problem in the adult population, has increased in recent years and is associated with noncommunicable diseases. Objectives. To make comparisons between anthropometric measurements and indices and to evaluate their relationship with individual and sociodemographic variables to generate information on the use of the main measurements in the evaluation of general and abdominal obesity as indicators of cardiovascular risk. Materials and methods . Secondary analysis of the ENSIN survey for Colombia with data collected between 2015 and 2016, the 2005 Population and Housing Census of the Departamento Administrativo Nacional de Estadística (DANE) was used as a sampling frame. The sample was 44,202 households with 151,343 people aged 0 to 64 years; 70,315 records of adult population were selected for this analysis. Proportions, confidence intervals, measures of central tendency and dispersion were calculated. Results. The means of body mass index (BMI) and waist-height index were higher than the cutoff point in both sexes, while the means of waist circumference were below the cutoff point for men and higher for women (p<0.05). The prevalence of obesity by BMI was 17.5%, while abdominal obesity by waist circumference and waist-height index of 50.2% and 62.6% respectively. Conclusions. Abdominal obesity regardless of the indicator used, is about 3 times higher than general obesity by BMI and waist-height index identifies more people, especially men, with abdominal obesity compared to waist circumference.

Relación entre actividad física, sedentarismo y obesidad en adultos, Colombia, 2015

Introducción. La inactividad física y los comportamientos sedentarios demostraron ser factores de riesgo en la prevalencia de enfermedades como la obesidad. Objetivo. Analizar la relación entre la actividad física, el sedentarismo y el estado nutricional en la población de 18 a 64 años en Colombia, 2015. Materiales y métodos. Se llevó a cabo el análisis secundario de la encuesta de nutrición de Colombia en 2015, utilizando variables sociodemográficas (edad, sexo, etnia, área geográfica, región e índice de riqueza) y, además, peso, talla, actividad física y sedentarismo. Se estimaron proporciones e intervalos de confianza al 95 %, utilizando la prueba de ji al cuadrado, regresión logística y razón de momios (Odds ratio). Resultados. La población analizada incluyó 16.607 individuos (54,8 % mujeres y 45,2 % hombres) de 18 a 64 años. Los hombres tuvieron más sobrepeso (37,6 %) que las mujeres, mientras que la obesidad fue más frecuente en mujeres (22,1 %). El 48,3 % no cumple con la recomendación de actividad física; 56,9 % de los adultos pasa dos o más horas al día mirando pantallas. Hubo una asociación significativa (p<0,050) entre el incumplimiento de las recomendaciones de actividad física y la obesidad. Además, el cumplir con la recomendación de actividad física disminuye 1,25 veces la probabilidad de obesidad. Conclusión. La obesidad es un problema de salud para la población adulta, con mayor prevalencia en las mujeres y en los mayores de 30 años. Se relaciona con el incumplimiento de las recomendaciones sobre actividad física y con los comportamientos sedentarios (los cuales son más prevalentes en los afrodescendientes), el cuartil alto de riqueza, el vivir en área urbana y el vivir en Bogotá.

Introduction. Physical inactivity and sedentary behaviors were shown to be risk factors in the prevalence of diseases such as obesity. Objective. To conduct an analysis of the relationship between physical activity, sedentary lifestyle and nutritional status in the population aged 18 to 64 years in Colombia, 2015. Materials and methods. A secondary analysis of the 2015 Colombian nutrition survey was done, using sociodemographic variables (age, sex, ethnicity, geographic area, region, wealth index), along with weight, height, physical activity and sedentary lifestyle. Proportions and 95% confidence intervals, chi-square, logistic regression and odds ratio were estimated. Results. The analyzed population included 16,607 individuals (54.8% women and 45.2% men) aged 18 to 64 years. Men were more overweight (37.6%) than women, while obesity was more frequent in women (22.1%). It was observed that 48.3% did not meet the physical activity recommendations; 56.9% of adults spent two or more hours a day watching screens. There was a significant association (p<0.050) between non-compliance with physical activity recommendations and obesity. In addition, complying with the physical activity recommendation decreases the probability of obesity by 1.25 times. Conclusion. Obesity is a health problem for the adult population, with a higher prevalence in women and in those over 30 years old. It is related to non-compliance with the recommendations about physical activity and sedentary behaviors (which are more prevalent in Afro-descendants), high wealth quartile status, and to reside in urban areas and to live in the Bogotá area.

The impact of socioeconomic status on the survival of men with early-onset prostate cancer.

Prostate cancer (PCa) is generally considered a disease of older men; however, about 10% of new diagnoses in the US occur in men ≤ 55 years old. Socioeconomic status (SES) has been shown to influence survival in patients with PCa; however, the impact of SES on men with early-onset PCa remains undescribed. Using the National Cancer Database, we identified adult men ≤ 55 years of age with a diagnosis of prostatic adenocarcinoma between 2004-2018. Descriptive statistics were used to characterize differences among different SES groups. Kaplan-Meier (KM) and Cox regression analyses were used to assess the effect of SES on overall survival (OS). A total of 112,563 young patients with PCa with a median follow-up of 79.0 months were identified. Compared to high SES patients, low SES patients were more likely to be African American (42.4% vs. 8.6%; P<0.001), Hispanic (9.5% vs. 2.7%; P<0.001), and uninsured (5.2% vs. 1.1%; P<0.001); they were also more likely to live in a rural area (3.2% vs. 0.1%; P<0.001) and have stage IV disease (5.5% vs. 3.1%; P<0.001). KM analysis showed that a decreasing SES was directly associated with lower rates of OS (log-rank test P<0.001). On multivariable analysis, SES was found to have a negative effect on OS (low SES vs. high SES; hazard ratio [HR] 1.54; 95% confidence interval [CI] 1.41-1.68; P<0.001). In patients with early-onset PCa, SES was associated with lower OS. SES may be considered when implementing programs to improve the management of patients with early-onset PCa.

Glomerular hyperfiltration is a predictor of adverse outcomes following major urologic oncology surgery.

PURPOSE: Glomerular hyperfiltration (GHF) has been associated with cardiovascular disease and all-cause mortality. We aimed to evaluate whether preoperative GHF is associated with 30-day complications following major urologic oncology procedures. METHODS: We conducted a retrospective cohort study using subjects from the 2006 to 2019 American College of Surgeons National Surgical Quality Improvement Program database who underwent prostatectomy, cystectomy, or nephrectomy. Estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI equation. Patients were classified as having either low, normal, or high eGFR based on the 5th and 95th percentiles of age- and sex-specific quintiles for eGFR. Using multivariable logistic regression, we evaluated GHF as an independent predictor of postoperative complications. RESULTS: A total of 120,013 patients were eligible for analysis, of which 1706 (1.4%) were identified as having GHF, with a median eGFR of 105.37 ml/min per 1.73 m2 (IQR 94.84-116.77). Compared to patients with normal eGFR, patients with GHF were older (68 years, [IQR 60-71], p < 0.001), had a lower BMI (27.52 kg/m2 [IQR 23.71-31.95], p < 0.001), and greater 5-item modified frailty index scores (≥ 1, 70.6%, p < 0.001). Multivariable logistic regression demonstrated that GHF was associated with greater odds of any complication (OR 1.23, 95% CI 1.08-1.40, p = 0.002), non-home discharge (OR 1.86, 95% CI 1.50-2.30, p < 0.001), and prolonged LOS (OR 1.33, 95% CI 1.18-1.51, p < 0.001). CONCLUSION: GHF is associated with greater odds of 30-day complications following major urologic oncology surgery.

Does Moses technology improve the efficiency and outcomes of standard holmium laser lithotripsy? A systematic review and meta-analysis.

Introduction: Retrograde ureteroscopy with holmium laser lithotripsy (HLL) is a standard treatment for urolithiasis. Moses technology has been shown to improve fragmentation efficiency in vitro; however, it is still unclear how it performs clinically compared to standard HLL. We performed a systematic review and meta-analysis evaluating the differences in efficiency and outcomes between Moses mode and standard HLL. Material and methods: We searched the MEDLINE, EMBASE, and CENTRAL databases for randomized clinical trials and cohort studies comparing Moses mode and standard HLL in adults with urolithiasis. Outcomes of interest included operative (operation, fragmentation, and lasing times; total energy used; and ablation speed) and perioperative parameters (stone-free rate and overall complication rate). Results: The search identified six studies eligible for analysis. Compared to standard HLL, Moses was associated with significantly shorter average lasing time (mean difference [MD] -0.95, 95% confidence interval [CI] -1.22 to -0.69 minutes), faster stone ablation speed (MD 30.45, 95% CI 11.56-49.33 mm3/min), and higher energy used (MD 1.04, 95% CI 0.33-1.76 kJ). Moses and standard HLL were not significantly different in terms of operation (MD -9.89, 95% CI -25.14 to 5.37 minutes) and fragmentation times (MD -1.71, 95% CI -11.81 to 8.38 minutes), as well as stone-free (odds ratio [OR] 1.04, 95% CI 0.73-1.49) and overall complication rates (OR 0.68, 95% CI 0.39-1.17). Conclusions: While perioperative outcomes were equivalent between Moses and standard HLL, Moses was associated with faster lasing time and stone ablation speeds at the expense of higher energy usage.

Characteristics of the high ioduria concentrations in schoolchildren and adolescents in Colombia. / Características de las concentraciones elevadas de yoduria en escolares y adolescentes de Colombia.

OBJETIVES: To determine the characteristics of high ioduria concentrations in schoolchildren and adolescents in Colombia. MATERIALS AND METHODS: Secondary analysis of the 2015 National Survey of the Nutritional Situation in Colombia in participants aged 5 to 17 years, which included the measurement of ioduria. The criteria to measure the nutritional status of iodine were based on the median urinary iodine concentration in µg / L defined by the World Health Organization (WHO), where values ​​<100 are considered deficient, between 100-199 adequate, 200-299 above the requirements and> 300 excessive. Odds ratio measurements were also performed through logistic regression analysis. RESULTS: The national median iodine for schoolchildren and adolescents was 406.8 µg / L and 410.8 µg / L respectively, higher in the urban area (410.5 µg / L), in the Atlantic region the highest level was found for schoolchildren (423.7 µg / L) and in the central for adolescents (427.7 µg / L). 4.4% of schoolchildren and 2.2% of adolescents presented deficiency and in more than 75% of the population, there was excessive intake of iodine. The factors associated with excessive iodine intake in schoolchildren were age, ethnicity, region and wealth index, and for adolescents gender and geographic area. CONCLUSIONS: The iodine concentrations in Colombian schoolchildren and adolescents are higher than adequate according to WHO, the deficiency is very low and a serious public health problem occurs due to excessive iodine intake in three-quarters of the population.

Isolation of Bacillus cereus in school restaurants in Colombia

Introduction: Bacillus cereus is recognized as a pathogen that causes food poisoning. It is a facultative aerobic metabolism bacterium capable of forming spores, which allows it to survive pasteurization and heating even by the gamma irradiation used to reduce pathogens in food. Objective: To study the presence of Bacillus cereus and its diarrheal toxin in rice and ready-to-eat cereals, flours, and starches in school restaurants in Colombia. Materials and methods: We conducted a descriptive cross-sectional study of ready-to-eat foods distributed in school restaurants in the departments with the most and the least notification of foodborne diseases to the surveillance system. Results: A total of 479 samples were collected from eight departments, 74 municipalities, and 363 school restaurants, 63% of which were rice samples and 37%, starchy food samples; 9% of them tested positive for Bacillus cereus. In 91% of the samples that tested positive, the bacterium was isolated with the presence of the diarrheal toxin. Conclusions: In all the departments with B. cereus in the samples, the factors directly related to food-borne diseases were the handling of raw materials and the poor thermal treatment of food. Strengthening surveillance by stimulating research and reporting on outbreaks of foodborne diseases is important to improve the quality of information, to develop communication, prevention and intersectional coordination and manipulation measures, as well as to take the necessary actions to guarantee the safety of food and to eliminate the risk factors that may contribute to this problem.

Feeding in adults with type II diabetes mellitus in three public hospitals in Cundinamarca, Colombia

Introduction: Type II diabetes mellitus (DMII) is one of the main causes of morbidity and mortality both worldwide and in Colombia. It mainly affects men and women over 45 years of age. Inadequate control of this disease can generate greater health complications making it one of the most costly diseases in the country. Treatment includes activities other than glycemic control and requires constant monitoring by medical personnel and educational processes directed at the patient and his or her family. Objective: To characterize the feeding of patients with DMII in three public hospitals of Cundinamarca. Materials and methods: We conducted a cross-sectional descriptive study of 212 patients that analyzed sociodemographic characteristics, frequency of consumption and feeding practices. Results: Most of the population was over 45 years old and had a low educational level. In total, 52% had a dietary plan, but only 8.9% received nutritional guidance from a nutritionist. The consumption of carbohydrates predominated, with low consumption of proteins, vitamins, minerals, and fiber. The consumption of sugars was lower in patients with a dietary plan (p <0.05). Conclusions: Most of the patients did not have an adequate nutrition; moreover, there was low adherence to dietary treatment, weakness in nutritional counseling and barriers to food access. These results can contribute to improving policies for the prevention and control of DMII and strategies based on the sociocultural context of the patients.

Modelamiento del control de población de palomas (Columba-livia) en la Plaza de Bolívar de Bogotá / Control Modeling for the Pigeon Population (Columba-livia) at the Plaza de Bolívar in Bogotá / Modelagem de controle da população de pombos (Columba-livia) na Praça de Bolívar em Bogotá

Resumen Introducción: Las palomas (Columba livia) son parte cultural de los centros históricos de las grandes ciudades del mundo -entre ellos la Plaza de Bolívar de la ciudad de Bogotá, Colombia-, sin embargo, son una especie invasora que puede llegar a ser una amenaza para la salud pública de los visitantes de la Plaza, razón por la cual es necesario controlar el incremento neto de estas aves sin buscar su extinción. Objetivo: En este trabajo se construyó un modelo matemático del crecimiento de la población de palomas, bajo una serie de pulsos de control a través del tiempo, para observar el comportamiento de desarrollo controlado de estas aves. Materiales y métodos: Como herramienta principal se utilizó la metodología de modelamiento conocida como Dinámica de Sistemas, la cual permite obtener un sistema de ecuaciones diferenciales a partir de una representación sistémica de un problema. Resultados: Los resultados indican que la simulación de este tipo de control permite que la población de palomas se mantenga dentro de un rango aceptable para el espacio. Conclusiones: Este trabajo se considera un gran aporte en la simulación y evaluación de escenarios para el control de población de palomas, mediante la evaluación con Dinámica de Sistemas y puede reproducirse para otras especies problema.

Abstract Introduction: The pigeons (Columba livia) are a cultural part of the historical centers of the great cities of the world; however, they are an invasive species that can become a threat to the public health of visitors to the Plaza de Bolívar in Bogotá, which is why it is necessary to control the net increase of these birds, without seeking extinction. Objective: In this work a mathematical model of the population growth of pigeons was constructed, under a series of control pulses through time, to observe the behavior of controlled development of these birds. Materials and Methods: As a main tool we used the modeling methodology known as System Dynamics, which allows us to obtain a system of differential equations from a systemic representation of a problem. Results: The results indicate that the simulation of this type of control allows the population of pigeons to remain within an acceptable range for space. Conclusions: This work is considered a great contribution in the simulation and evaluation ofscenarios for the population control of pigeons, through the evaluation with Systems Dynamics and can be reproduced for other problem species.

The dual burden of malnutrition in Colombia.

BACKGROUND: Almost all nutrition policies in Colombia currently focus on either undernutrition or obesity, with the predominant emphasis on undernutrition. It is crucial to assess the prevalence of the dual burden of malnutrition in Colombia to better target programs and policies. OBJECTIVE: The aim was to estimate the national prevalence of the dual burden of malnutrition in Colombia at the individual and household levels in children aged <5 y, school-age children, adolescents, and adults. DESIGN: This was a cross-sectional analysis from the 2010 Colombian Demographic and Health Survey and the National Nutritional Survey that included 17,696 children aged <5 y, 25,508 school-aged children, 28,328 adolescents, 89,164 adults, and 10,487 households with mothers and children aged <5 y. The dual burden of malnutrition was defined as the coexistence of overweight and stunting or anemia in the same person or household. RESULTS: In Colombia, low to high prevalences of overweight and obesity (3.4-51.2%) coexist with moderate to high prevalences of anemia (8.1-27.5%) and stunting (13.2%). The observed prevalence of the dual burden was lower than expected. Approximately 5% of households had at least one stunted child aged <5 y and an overweight mother compared with an expected prevalence of 6.9% (P < 0.001). Among school-aged children, 0.1% were classified as stunted and obese and 1.4% were both anemic and overweight compared with expected prevalences of 0.5% (P < 0.001) and 1.5% (P = 0.037), respectively. Among 13- to 49-y-old women, 3.4% had anemia and were overweight compared with an expected prevalence of 3.5% (P = 0.038). CONCLUSIONS: National estimates of the dual burden of malnutrition in Colombia are lower than expected. Despite the independence of the occurrence of these conditions, the fact that the dual burden coexists at the national, household, and intraindividual levels suggests that public policies should address both conditions through multiple strategies. It is imperative to evaluate the current nutrition policies to inform malnutrition prevention efforts in Colombia and to share lessons with other countries at a similar stage of nutritional transition.
