Calidad de vida en pacientes con tumor vesical no músculo-invasivo sometidos a tratamiento adyuvante intravesical / Quality of life in patients with non-muscle invasive bladder tumor undergoing adjuvant intravesical treatment

Introducción El objetivo del estudio fue establecer posible relación entre los tratamientos con mitomicina-C (MMC) y bacilo de Calmette-Guérin (BCG) y la afectación en la calidad de vida. Material y métodos Estudio cuasiexperimental, prospectivo y longitudinal, recogiendo pacientes sometidos a tratamiento adyuvante en TVNMI. Se utilizaron los cuestionarios Short form-12 (SF-12) y Urogenital Distress Inventory-6 (UDI-6) para medir la calidad de vida. Se compararon las puntuaciones de los cuestionarios entre casos con MMC y BCG antes de iniciar la inducción (M1), a las 4 semanas (M2) y a los dos meses (M3). Resultados Se recogieron 90 pacientes, 54 en el grupo de BCG y 36 en el de MMC. Se comprobó que los pacientes con BCG percibían peor calidad de vida física comparados con los de MMC en M2 (OR:2,59, p=0,046). Además, se hallaron cambios significativos en la calidad de vida urinaria de los pacientes en tratamiento con MMC entre los diferentes momentos temporales (puntuación del UDI-6: 33,33 en M1, 27,78 en M2 y 16,67 en M3, p=0,001). Conclusiones No existen diferencias en la calidad de vida urinaria entre los pacientes tratados con MMC y BCG. Los pacientes con MMC muestran una recuperación significativa de la calidad de vida urinaria a partir de la finalización de la inducción, que aumenta aún más a los dos meses de la misma. Además, los pacientes tratados con BCG presentan peor calidad de vida física a las 4 semanas de tratamiento que aquellos tratados con MMC (AU)

Introduction The objective of the study was to establish a possible relationship between mitomycin-C (MMC) and bacillus Calmette-Guérin (BCG) treatments and quality of life impairment. Material and methods Quasi-experimental, prospective, and longitudinal study including patients undergoing adjuvant treatment in NMIBC. The Short form-12 (SF-12) and Urogenital Distress Inventory-6 (UDI-6) questionnaires were used to measure quality of life. Questionnaire scores were compared between cases with MMC and BCG before induction (M1), at 4 weeks (M2) and at 2 months (M3). Results Of the 90 patients enrolled, 54 were in the BCG group and 36 in the MMC group. It was found that BCG patients had worse perceived physical quality of life compared to MMC patients in M2 (OR:2.59, p=0.046). In addition, significant changes were found in the urinary quality of life of patients on MMC treatment between the different time points (UDI-6 score: 33.33 in M1, 27.78 in M2 and 16.67 in M3, p=0.001). Conclusions There are no differences in urinary quality of life between patients treated with MMC and BCG. Patients with MMC show a significant recovery of urinary quality of life from the completion of the induction course, which becomes even more significant after 2 months. In addition, BCG-treated patients have worse physical quality of life after 4 weeks of treatment than those treated with MMC (AU)

Are Fragrance Encapsulates Taken Up by Aquatic and Terrestrial Invertebrate Species?

The uptake potential of fragrance encapsulates by aquatic or terrestrial organisms was investigated. Because of their size of <5 mm and their polymeric nature, fragrance encapsulates fall under the Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection definition of microplastics. After use, fragrance encapsulates enter the sewer system and reach the sewage treatment plant (STP), where >90% of them are likely to be removed by sorption to the sludge. When the STP-generated sludge is used as fertilizer for agricultural soils, this may lead to potential exposure of terrestrial invertebrates to fragrance encapsulates, especially those feeding on particles of a similar size as the fragrance encapsulates. Two aquatic (Corbicula fluminea [water exposure] and Hyalella azteca [water and dietary exposure]) and one terrestrial invertebrate (Eisenia andrei [soil exposure]) species were exposed to 50 mg/L (or mg/kg) double fluorescence-labeled fragrance encapsulates (diameter 5-50 µm). The results showed that fragrance encapsulates are available to aquatic and terrestrial invertebrates but that species-specific differences regarding the ability to ingest fragrance encapsulates may exist. The benthic grazer H. azteca showed no ingestion of fragrance encapsulates, whereas the capsules were readily ingested and egested by the unselective freshwater filter feeder C. fluminea as well as the terrestrial decomposer E. andrei. No signs of bioaccumulation of fragrance encapsulates were indicated by microscopic assessment. Environ Toxicol Chem 2022;41:931-943. © 2021 The Authors.

Acute respiratory distress syndrome due to COVID-19. Clinical and prognostic features from a medical Critical Care Unit in Valencia, Spain / Síndrome de dificultad respiratoria aguda asociado a la COVID-19. Características clínicas y de pronóstico en una unidad de cuidados intensivos de Valencia, España

OBJECTIVE: Information from critically ill coronavirus disease 2019 (COVID-19) patients is limited and in many cases coming from health systems approaches different from the national public systems existing in most countries in Europe. Besides, patient follow-up remains incomplete in many publications. Our aim is to characterize acute respiratory distress syndrome (ARDS) patients admitted to a medical critical care unit (MCCU) in a referral hospital in Spain. DESIGN: Retrospective case series of consecutive ARDS COVID-19 patients admitted and treated in our MCCU. SETTING: 36-bed MCCU in referral tertiary hospital. PATIENTS AND PARTICIPANTS: SARS-CoV-2 infection confirmed by real-time reverse transcriptase–polymerase chain reaction (RT-PCR) assay of nasal/pharyngeal swabs. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Demographic and clinical data were collected, including data on clinical management, respiratory failure, and patient mortality. RESULTS: Forty-four ARDS COVID-19 patients were included in the study. Median age was 61.50 (53.25 - 67) years and most of the patients were male (72.7%). Hypertension and dyslipidemia were the most frequent co-morbidities (52.3 and 36.4% respectively). Steroids (1mg/Kg/day) and tocilizumab were administered in almost all patients (95.5%). 77.3% of the patients needed invasive mechanical ventilation for a median of 16 days [11-28]. Prone position ventilation was performed in 33 patients (97%) for a median of 3 sessions [2-5] per patient. Nosocomial infection was diagnosed in 13 patients (29.5%). Tracheostomy was performed in ten patients (29.4%). At study closing all patients had been discharged from the CCU and only two (4.5%) remained in hospital ward. MCCU length of stay was 18 days [10-27]. Mortality at study closing was 20.5% (n 9); 26.5% among ventilated patients. CONCLUSIONS: The seven-week period in which our MCCU was exclusively dedicated to COVID-19 patients has been challenging. Despite the severity of the patients and the high need for invasive mechanical ventilation, mortality was 20.5%

Impact of a 2-year intervention program on cardiometabolic profile according to the number of goals achieved.

We investigated the impact of lifestyle goal achievement on cardiovascular risk factors after a 2-year behavioral intervention program applied to 394 adults (113 with diabetes, mean age 60.2 ± 11.4 years, 56% women) and targeting four goals: ≥5% weight loss; ≥150 min/week physical activities; <10% saturated fat intake/day; ≥400 g fruit and vegetable intake/day. Baseline characteristics and changes in variables after intervention among the four categories of number of goals achieved (none, 1, 2, and ≥3) were compared by independent ANOVA or the Kruskal-Wallis test. Individuals without diabetes achieving a higher number of goals were more likely to be older (3 or 4 goals: 61.8 ± 12.6 years vs none: 53.3 ± 10.3 years, P < 0.05) and to have a lower mean BMI (3 or 4 goals: 21.7 ± 2.6 kg/m² vs none: 29.0 ± 4.8 kg/m², P < 0.05), diastolic blood pressure (3 or 4 goals: 77.3 ± 2.1 mmHg vs none: 85.4 ± 9.6 mmHg, P < 0.05), triglyceride (3 or 4 goals: 116.1 ± 95.1 mg/dL vs none: 144.8 ± 65.5 mg/dL, P < 0.05) and insulin levels (3 or 4 goals: 3.6 ± 2.4 µU/L vs none: 5.7 ± 4.0 µU/L, P < 0.05) than those achieving fewer goals. The absolute changes in cardiovascular risk factors tended to be more pronounced with increasing number of goals achieved in individuals without diabetes. The intervention had a beneficial impact on the cardiometabolic profile of individuals with normal or altered glucose metabolism. The number of goals achieved in this lifestyle intervention was associated with the magnitude of improvement of cardiovascular risk factors in individuals without diabetes. Participants with a better cardiometabolic profile seemed to be more likely to have a healthy lifestyle.

[Effect of gastric bypass on the metabolic syndrome and on cardiovascular risk]. / Efecto del bypass gástrico en el síndrome metabólico y en el riesgo cardiovascular.

BACKGROUND: Obesity is associated with increased morbimortality cardiovascular. Individual with metabolic syndrome (MS) are a high risk of developing cardiovascular disease (CVD). The aim of this study was to determine the prevalence of the MS in morbidly obese patients enrolling in a bariatric surgery program and to evaluate the impact of weigh loss induced by gastric bypass on the MS and on the predicted 10-year cardiovascular risk. MATERIAL AND METHODS: We studied 46 morbidly obese patients who underwent laparoscopic gastric bypass and were followed for 2 years. MS was defined following the IDF 2005 criteria and the insulin resistance (IR) was calculated by using HOMA index. Risk assessment for estimating 10-year ECV risk was carried out according to Framingham score. RESULTS: Before surgery, 67.2% of patients had IR and 60,9% met the definition of the MS. 17.3% of patients had an elevated cardiovascular risk category. 2 years after gastric bypass, the percentage of excess body weight lost was 72%. All patients restored their HOMA index and only 1 patient (3.6%) had MS. Resolution of hypertension, disglucemia and dislipemia has been observed in 85%, 93.8% and 95.6% of patients. Estimated cardiovascular risk decreased from 4.5% at baseline to 1% at 2 years after surgery. CONCLUSIONS: SM is common in morbidly obese patients. Bypass gastric is associated with an improvement or resolution in cardiovascular risk factors and IR and result in a significant reduction in MS prevalence and of predicted 10-year cardiovascular risk.

Efecto del bypass gástrico en el síndrome metabólico y en el riesgo cardiovascular / Effect of gastric bypass on the metabolic syndrome and on cardiovascular risk

Antecedentes: La obesidad se asocia con un aumento de la morbimortalidad cardiovascular. Los individuos con síndrome metabólico (SM) presentan un alto riesgo de desarrollar enfermedad cardiovascular (ECV). El objetivo de este trabajo ha sido determinar la prevalencia del SM en pacientes con obesidad mórbida incluidos en un programa de cirugía bariátrica y evaluar el impacto que la pérdida de peso inducida por el bypass gástrico ejerce en el SM y en el riesgo cardiovascular estimado a los 10 años. Material y métodos: Hemos estudiado a 46 pacientes con obesidad mórbida a los que se les practicó un bypass gástrico laparoscópico y se siguió durante 2 años. El SM fue definido según los criterios de la IDF 2005 y la resistencia a la insulina (RI) se calculó mediante el índice HOMA. La estimación del riesgo de ECV a los 10 años se determinó de acuerdo con el algoritmo de Framingham. Resultados: Previo a la cirugía, el 67,2% de los pacientes presentaban RI y el 60,9% cumplían criterios de SM. En el 17,3% de los enfermos se categorizó un nivel de riesgo cardiovascular elevado. A los 2 años tras el bypass gástrico, el porcentaje de exceso de peso perdido fue del 72%. Todos los pacientes normalizaron su índice HOMA y solo 1 enfermo (3,6%) presentaba SM. La resolución de la hipertensión, disglucemia y dislipemia ocurrió en el 85%, 93,8% y 95,6% de los casos. El riesgo cardiovascular estimado disminuyó de forma significativa desde un 4,5% al inicio del estudio hasta un 1% a los 2 años tras la cirugía. Conclusiones: el SM es frecuente en pacientes con obesidad mórbida. El bypass gástrico se asocia con una mejoría o resolución de la RI y de los principales factores de riesgo cardiovascular y en consecuencia reduce de forma significativa la prevalencia del SM y del riesgo cardiovascular estimado a los 10 años (AU)

Birthweight and the risk of childhood-onset type 1 diabetes: a meta-analysis of observational studies using individual patient data.

AIMS/HYPOTHESIS: We investigated whether children who are heavier at birth have an increased risk of type 1 diabetes. METHODS: Relevant studies published before February 2009 were identified from literature searches using MEDLINE, Web of Science and EMBASE. Authors of all studies containing relevant data were contacted and asked to provide individual patient data or conduct pre-specified analyses. Risk estimates of type 1 diabetes by category of birthweight were calculated for each study, before and after adjustment for potential confounders.Meta-analysis techniques were then used to derive combined ORs and investigate heterogeneity between studies. RESULTS: Data were available for 29 predominantly European studies (five cohort, 24 case-control studies), including 12,807 cases of type 1 diabetes. Overall, studies consistently demonstrated that children with birthweight from 3.5 to 4 kg had an increased risk of diabetes of 6% (OR 1.06 [95% CI 1.01-1.11]; p=0.02) and children with birthweight over 4 kg had an increased risk of 10% (OR 1.10 [95% CI 1.04-1.19]; p=0.003), compared with children weighing 3.0 to 3.5 kg at birth. This corresponded to a linear increase in diabetes risk of 3% per 500 g increase in birthweight (OR 1.03 [95% CI 1.00-1.06]; p=0.03). Adjustments for potential confounders such as gestational age, maternal age, birth order, Caesarean section, breastfeeding and maternal diabetes had little effect on these findings. CONCLUSIONS/INTERPRETATION: Children who are heavier at birth have a significant and consistent, but relatively small increase in risk of type 1 diabetes.

Cardiovascular risk factors among Brazilian Karib indigenous peoples: Upper Xingu, Central Brazil, 2000-3.

BACKGROUND: Brazil has more than 200 indigenous peoples with 170 different languages that result in different epidemiological and demographic situations. The objective of this study was to describe the nutritional and metabolic profile of the adult Karib indigenous peoples, inhabitants of the Upper Xingu region, as well as to evaluate their possible effects on their cardiovascular health. METHODS: In 2002, the Karib population comprised 1091 individuals, 390 of whom (35.7%) were 20 years of age or older. This study was based on results from 251 adult individuals (64.4%). chi(2) statistics were used to evaluate the possible relationship between chronic diseases and tribe, gender and age. Analysis of variance was used to compare the average values of the biomedical variables of the individuals according to tribe and gender. RESULTS: The prevalence of the main risk factors detected was: 39.3% overweight and 6.8% obese, mainly among men (60.4%), 41.8% for central obesity mainly among women (66.7%), 68% for dyslipidaemia and 15.4% for blood pressure alterations mainly among men (24.7%). Overall, percentages were higher than in the non-indigenous Brazilian population. The percentage of individuals presenting simultaneously with at least two cardiovascular risk factors (29%) was also remarkable. CONCLUSIONS: These findings emphasize the need to implement preventive health measures to control obesity and other cardiovascular risk factors in indigenous peoples.

Dietary fructose, fruits, fruit juices and glucose tolerance status in Japanese-Brazilians.

BACKGROUND AND AIMS: Evidence suggests that fructose and sweetened beverages may be a risk factor for obesity and type 2 diabetes, but the role of sweetened fruit juices in glucose disturbances has been minimally explored. The aim of this study was to examine the association of total fructose, fresh fruit and sweetened fruit juice intake with glucose tolerance homeostasis in Japanese-Brazilians. METHODS AND RESULTS: A total of 475 men and 579 women aged >or=30 years were evaluated in a cross-sectional population-based survey with a standardized protocol including a 2-h oral glucose tolerance test (WHO criteria). Habitual food consumption was obtained using a validated food frequency questionnaire for Japanese-Brazilians. After adjustments for potential confounding variables, the odds ratio (OR; 95%CI) for impaired glucose tolerance was 2.1 (1.0-4.5; P for trend=0.05) for the highest as compared to the lowest tertile intake of total fructose and 2.3 (1.1-5.1; P for trend=0.05) for the highest as compared to the lowest tertile intake of sweetened fruit juices. CONCLUSION: Our results showed that high intakes of dietary fructose and sweetened fruit juices, but not whole fresh fruits, were associated with impaired glucose tolerance among genetically susceptible individuals.

Development of chronic tests for endocrine active chemicals. Part 1. An extended fish early-life stage test for oestrogenic active chemicals in the fathead minnow (Pimephales promelas).

An extended early-life stage test (based on OECD test guideline 210) was developed to allow the evaluation of a weak environmental oestrogen, 4-tert-pentyphenol (4TPP), on sexual differentiation and gonadal development. Fathead minnow (Pimephales promelas) embryos were exposed to three concentrations of 4TPP (56, 180 and 560 microg l(-1)) in a flow-through system, at 25+/-1 degrees C, for <107 days post-hatch (dph). In addition, some embryos were exposed to 180 microg 4TPPl(-1) until 30 or 60 dph, after which they were exposed to dilution water only until 107 dph. At 30, 60 and 107 dph fish were evaluated for growth and gonadal development (via histology), and at 107 dph fish were also evaluated for secondary sexual characteristics (SSC), gonadosomatic index (GSI) and plasma vitellogenin (VTG). There were no effects of 4TPP on hatching success or survival, however, there was a delay in the time taken for embryos to hatch (560 microg 4TPPl(-1)). No treatment-related effects were observed on fish growth, with the exception of at 107 dph when the condition factor in female fish was reduced in all 4TPP continuous exposure treatments. Plasma VTG was only elevated in female fish exposed to 180 microg 4TPPl(-1) and inhibition of gonadal growth (GSI) occurred only in females exposed to 560 microg 4TPPl(-1). Histological examination of the gonads revealed delays and disruption in male sexual differentiation and development (180 microg 4TPPl(-1)) and no testicular tissue was observed in any fish exposed to 560 microg 4TPPl(-1). Mixed gonads (predominately testes with a scattering of primary oocytes) were present in fish exposed to all doses of 180 microg 4TPPl(-1) at 107 dph. Feminisation of the reproductive ducts (formation of an ovarian like cavity) occurred in the testis of all males exposed to 180 microg l(-1), regardless of length of 4TPP exposure. Results indicate that the period of 30-60 dph appears to be the sensitive window for disruption of formation of the reproductive duct and this effect is not reversible when the fish are transferred to dilution water. The data also show that this integrative test is suitable for the detection of a weak environmental oestrogen and comparisons of these results with that of a fish full life-cycle, in medaka, indicate that this test could be a suitable surrogate for a fish full life-cycle.

Leptin is not associated independently with hypertension in Japanese-Brazilian women.

We evaluated the relationship of leptin with hypertension adjusted for body mass index (BMI) and/or waist circumference in a population of Japanese-Brazilian women aged > or = 30 years with centrally distributed adiposity. After excluding diabetic subjects, the study subjects--who participated in a population-based study on the prevalence of metabolic syndrome--showed prevalence rates of obesity (BMI > or = 25 kg/m2) and central adiposity (waist > or = 80 cm) of 32.0 and 37.8%, respectively. The hypertensive group (N = 162) was older, had higher BMI (24.9 +/- 4.2 vs 23.3 +/- 3.4 kg/m2, P < 0.001), waist circumference (81.1 +/- 10.1 vs 76.3 +/- 8.2 cm, P < 0.001) and insulin levels (8.0 +/- 6.2 vs 7.1 +/- 4.9 microU/mL, P < 0.05) than the normotensive group (N = 322) and showed an unfavorable metabolic profile (higher 2-h plasma glucose, C-reactive protein and non-HDL cholesterol levels). Leptin did not differ between groups (8.2 +/- 6.8 vs 7.2 +/- 6.6 ng/mL, P = 0.09, for hypertensive vs normotensive, respectively) and its levels correlated significantly with anthropometric variables but not with blood pressure. Logistic regression analysis indicated that age and waist were independently associated with hypertension but not with homeostasis model assessment of insulin resistance or leptin levels. The lack of an independent association of hypertension with metabolic parameters (2-h glucose, C-reactive protein and non-HDL cholesterol) after adjustment for central adiposity suggested that visceral fat deposition may be the common mediator of the disturbances of the metabolic syndrome. Our data indicate that age and waist are major determinants of hypertension in this population of centrally obese (waist > or = 80 cm) Japanese-Brazilian women, but do not support a role for leptin in the elevation of blood pressure.

Analysis of criteria for metabolic syndrome in a population-based study of Japanese-Brazilians.

OBJECTIVE: Criteria for metabolic syndrome (MS) differ particularly regarding the definition of central obesity and consequently, there could be differences in the assessment of cardiovascular risk. We estimated the prevalence of metabolic syndrome, compared the agreement of the World Health Organization (WHO) criteria with the standard and a modified National Cholesterol Education Program (NCEP) criterion and investigated whether additional factors were associated with the diagnosis of the syndrome in a Japanese descendant population. METHODS: In this cross-sectional, population-based survey, 1166 Japanese-Brazilians (533 men, 633 women) aged 57.4 +/- 12.4 years with mean body mass index (BMI) and waist of 25.2 +/- 4.0 kg/m(2) and 84.5 +/- 10.6 cm, respectively, were included. McNemar and kappa statistics were used to assess the concordance between WHO criteria with the standard and a modified NCEP criteria (waist of 90 and 80 cm, for men and women, respectively). In logistic regression analysis, a number of metabolic variables and albumin-to-creatinine ratio were included to test independent associations with metabolic syndrome defined by the modified NCEP criteria. RESULTS: According to WHO, 55.4% (95% CI 52.5-58.2%) of the subjects had MS and to NCEP 47.4% (95% CI 44.6-50.0%). WHO criterion detected 48.3% of central obese subjects while NCEP only 14.0%. Kappa statistics showed a good strength of agreement (k = 0.67, p < 0.01) between WHO and NCEP standard definitions of MS. Using the modified NCEP criterion for Asians, more subjects with metabolic syndrome were identified (58%) and agreement with WHO was improved (k = 0.72, p < 0.001). However, similar Framingham risk scores were attributed to the subsets of subjects classified by any of the three criteria. Areas under the receiver operating characteristic curves, obtained for the modified waist values to diagnose metabolic syndrome according to WHO, were > 0.80 and corresponded, respectively, to sensitivity and specificity of 63 and 83% for men and 77 and 72% for women. In final logistic regression model, age, male sex, BMI and homeostasis model assessment-insulin resistance but not with albumin-to-creatinine ratio (ACR) were independently associated with the syndrome. CONCLUSIONS: High prevalence of MS, independent of the criterion considered, was found in this Japanese-Brazilian population. The replacement of waist cutoff by those proposed by WHO for Asians lead to this diagnosis in a higher number of subjects with elevated cardiovascular risk. Our data did not support that ACR should be included in the classical definition of MS in Japanese descendants as previously suggested by WHO.

Independent impact of glycemia and blood pressure in albuminuria on high-risk subjects for metabolic syndrome.

BACKGROUND: Microalbuminuria may reflect diffuse endothelial damage. Considering that diabetes and hypertension cause vasculopathy, we investigated associations of albumin-to-creatinine ratio (ACR) with plasma glucose and blood pressure levels in high-risk subjects for metabolic syndrome. METHODS: A sample of 519 (246 men) Japanese-Brazilians (aged 60 +/- 11 years), who participated in a population-based study, had their ACR determined in a morning urine specimen. Backward models of multiple linear regression were created for each gender including log-transformed values of ACR as dependent variable; an interaction term between diabetes and hypertension was included. RESULTS: Macroalbuminuria was found in 18 subjects. ACR mean values for subjects with normal glucose tolerance, impaired fasting glycemia, impaired glucose tolerance and diabetes were 9.9 +/- 6.0, 19.0 +/- 35.4, 20.7 +/- 35.4, and 33.9 +/- 55.0 mg/g, respectively. Diabetic subjects showed higher ACR than the others (p < 0.05). An increase in the proportion of albuminuric subjects was observed as glucose metabolism deteriorated (4.9, 17.0, 23.0 and 36.0%). Stratifying into 4 groups according to postchallenge glycemia (< 7.8 mmol/l, n = 91; > or = 7.8 mmol/l, n = 410) and hypertension, hypertensive and glucose-intolerant subgroups showed higher ACR values. ACR was associated with gender, waist circumference, blood pressure, plasma glucose and triglyceride (p < 0.05); albuminuric subjects had significantly higher levels of such variables than the normoalbuminuric ones. In the final models of linear regression, systolic blood pressure and 2-hour glycemia were shown to be independent predictors of ACR for both genders (p < 0.05). In men, also waist was independently associated with ACR. No interaction was detected between "diabetes and hypertension". CONCLUSIONS: These findings suggest that both glucose intolerance and hypertension could have independent but not synergistic effects on endothelial function--reflected by albumin loss in urine. Such hypothesis needs to be confirmed in prospective studies.

Prevalence and 7-year incidence of Type II diabetes mellitus in a Japanese-Brazilian population: an alarming public health problem.

AIMS/HYPOTHESIS: In 1993, the prevalence of glucose intolerance was studied in a sample of 647 first-generation and second-generation Japanese-Brazilians. Their cohort was followed until 2000, when a second survey was conducted, this included the first and second generations, aged 30 or more years. The aims were to estimate the prevalence of glucose intolerance and 7-yr incidence of Type II (non-insulin-dependent) diabetes mellitus in this population. METHODS: Prevalence rates were obtained for 1330 subjects examined in 2000. The incidence of diabetes mellitus was calculated for those classified as normal glucose tolerant in 1993 (n=253). A Student's t test and the Cox proportional hazard model were used in data analysis. RESULTS: In the year 2000, higher proportions of subjects were observed in all categories of glucose intolerance than those found in 1993. The overall incidence of diabetes was 30.9 per 1000 per year. A worse profile was observed among incident cases of diabetes, characterized by higher baseline values of anthropometric and metabolic variables as compared to those who had not developed diabetes. Analysis considering the simultaneous effects of demographic, nutritional and metabolic variables and physical activity levels for the development of diabetes showed that age, sex, waist circumference, fasting and 2-h plasma glucose concentrations were independent predictors. CONCLUSION/INTERPRETATION: Our data point towards a worsening of glucose tolerance status among Japanese-Brazilians, who show one of the highest prevalence rates of diabetes mellitus worldwide. This could reflect their strong genetic susceptibility associated with unfavourable environmental conditions.

[Risk factors for Hodgkin's lymphomas]. / Factores de riesgo para los linfomas de Hodgkin.

OBJECTIVE: To divulge the risk factors associated with Hodgkin's lymphoma (HL) in children and adults among pediatricians. METHODS: We performed a literature review of the last 25 years through the Medline, IAR Cancer, and Cancerlit databases. The search profile was "HL risk factors". The most interesting papers, as well as those cited and published more than 25 years prior to the search, were selected. RESULTS: The following risk factors for HL were reported with greater or lesser evidence: a) genetic (variation in the HLA class II region); b) viral infections (Epstein-Barr virus); c) childhood environment and socio-economic status; d) congenital and acquired immunodeficiency; e) medical conditions and f) occupational exposure (the wood industry and its derivatives). CONCLUSIONS: The etiology of most HL is unknown. The most important risk factors are: 1) genetic; 2) Epstein-Barr virus (infectious mononucleosis); 3) congenital and acquired immunodeficiency; 4) occupational exposure (the wood industry).
