Estudio de prevalencia de Síndrome de Apneas - Hipopneas Obstructivas del Sueño en pacientes con obesidad

Introducción: La obesidad es una enfermedad epidémica multifactorial en constante aumento en los últimos años. Asocia el desarrollo de múltiples patologías con aumento de la morbimortalidad, entre ellas el síndrome de apneas e hipopneas obstructivas del sueño (SAHOS). Objetivo: Estudiar la prevalencia de SAHOS en una población de obesos pertenecientes a un Programa de Obesidad y Cirugía Bariátrica de un hospital público de Montevideo. Metodología: Estudio observacional descriptivo de cohorte transversal. Se incluyeron pacientes en valoración preoperatoria desde abril 2015 a marzo 2020. Se les realizó una polisomnografía. Se evaluó la prevalencia de SAHOS y la relación con otros factores de riesgo cardiovascular. El análisis estadístico se realizó con SPSS versión 25.0. Resultados: Se estudiaron 358 pacientes con predominio del sexo femenino (86,3%), edad media de 42,8 ± 10,7 años y un índice de masa corporal (IMC) promedio de 50,1 ± 11,4 kg/m2. Se evidenció una prevalencia de SAHOS de 69%: 43,3% leve; 23,9% moderada y 32,8% severo. El Índice apnea hipopnea (IAH) se correlacionó positivamente con IMC (p ≤ 0,001). Se demostró la asociación de SAHOS con hipertensión arterial (HTA), diabetes 2 (DM2), sexo masculino e hipertrigliceridemia. Conclusiones: El SAHOS es altamente prevalente en la obesidad. Este estudio sugiere la realización de un screening en todos los obesos, así como su estudio con polisomnografía o poligrafía respiratoria a aquellos que vayan a someterse a una cirugía bariátrica.

Introduction: Obesity is a multifactorial epidemic disease that has been constantly increasing in recent years. It associates the development of multiple pathologies with increased morbidity and mortality, including obstructive sleep apnea and hypopnea syndrome (OSAHS). Objective: To study the prevalence of OSAHS in a population of obese patients belonging to an Obesity and Bariatric Surgery Program of a public hospital in Montevideo. Methodology: Observational descriptive cross-sectional study. Patients in preoperative evaluation were included from April 2015 to March 2020. A polysomnography was performed. The prevalence of OSAHS and the relationship with other cardiovascular risk factors were evaluated. Statistical analysis was performed with SPSS version 25.0. Results: 358 patients were studied, predominantly female (86.3%), mean age of 42.8 ± 10.7 years and mean BMI of 50.1 ± 11.4 kg/m2. A prevalence of OSAHS of 69% was evidenced: 43.3% mild; 23.9% moderate and 32.8% severe. The Apnea Hypopnea Index (AHI) was positively correlated with the Body Mass Index (BMI) (p=<0.001). The association of OSAHS with arterial hypertension (AHT), diabetes 2 (DM2), male gender and hypertriglyceridemia was demonstrated. Conclusions: OSAHS is highly prevalent in obesity. This study suggests screening all obese people, as well as polysomnography or respiratory polygraphy for those who are going to undergo bariatric surgery.

Systemic oxidative stress in children with cystic fibrosis with bacterial infection including Pseudomonas Aeruginosa.

INTRODUCTION: Oxidative stress (OS) occurs in cystic fibrosis (CF). OBJECTIVE: The objective of this work is to evaluate the influence of bacterial infection on biomarkers of OS (catalase [CAT], glutathione peroxidade [GPx], reduced glutathione [GSH]), markers of oxidative damage (protein carbonyls [PC], thiobarbituric acid reactive substances [TBARS]), together with the nutritional status and lung function in children with CF. METHODS: Cross-sectional study including CF group (CFG, n = 55) and control group (CG, n = 31), median age: 3.89 and 4.62 years, respectively. CFG was distributed into CFG negative bacteriology (CFGB-, n = 27) or CFG positive bacteriology (CFGB+, n = 28), and CFG negative Pseudomonas aeruginosa (CFGPa-, n = 36) or CFG positive Pseudomonas aeruginosa (CFGPa+, n = 19). RESULTS: Compared with CG, CFG (P = .034) and CFGB+ (P = .042) had lower body mass index-for-age z-score; forced expiratory volume in the first second was lower in CFGB+ and CFGPa+ (both P < .001). After adjusting for confounders and compared with CG: CFG showed higher TBARS (P ≤ .001) and PC (P = .048), and lower CAT (P = .004) and GPx (P = .003); the increase in PC levels was observed in CFGB+ (P = .011) and CFGPa+ (P = .001) but not in CFGB- (P = .510) and CFGPa- (P = .460). CONCLUSIONS: These results indicate a systemic OS in children with CF. The presence of bacterial infection particularly Pseudomonas aeruginosa seems to be determinant to exacerbate the oxidative damage to proteins, in which PC may be a useful biomarker of OS in CF.

"Packing" torácico en urgencias torácicas / Thoracic packing in thoracic emergencies

RESUMEN El control de daños es un procedimiento en tres etapas en pacientes con riesgo vital. Primera etapa: laparotomía abreviada para el control de sangrados y contaminación. Segunda etapa: en cuidados críticos para corregir alteraciones fisiológicas y tercera etapa: con resolución definitiva de las lesiones. Se describió el empaquetamiento (packing) torácico como adaptación del empaquetamiento abdominal como procedimiento contemporizador y hemostático. El objetivo fue presentar nuestra experiencia con la cirugía de empaquetamiento torácico y mostrar su utilidad en la cirugía de control de daños en tórax. Las lesiones traumáticas de tórax pueden ir desde lesiones de leve entidad hasta lesiones graves que amenacen la vida del paciente. La decisión de empaquetar el tórax se adopta al tomar contacto con un paciente "in extremis". En conclusión, el empaquetamiento torácico se muestra eficaz para el control del sangrado en pacientes que no admiten medidas definitivas para él.

ABSTRACT Damage control is defined as an approach with 3 stages in patients with life-threatening injuries. Stage I: abbreviated laparotomy for hemorrhage and contamination control. Stage II: intensive care management to correct physiologic abnormalities; and stage III: definitive repair of injuries. Thoracic packing, an adaptation of abdominal packing, was described as a temporary procedure for hemostatic control. The aim of this study is to report our experience with thoracic packing and show its usefulness in thoracic damage control surgery. Traumatic chest injuries vary from minor trauma to life-threatening injuries. The decision to perform thoracic packing is made during the contact with a critically ill patient. In conclusion, packing is effective for bleeding control in critically ill patients who are not suitable for definitive treatment.

Falla de sutura en cirugía colorrectal. Factores de riesgo y manejo terapéutico / Anastomotic failure in colorectal surgery. Risk factors and therapeutic management

Introducción: La dehiscencia anastomótica (DA) es una complicación de la cirugía colorrectal que determina alta morbimortalidad y peor pronóstico oncológico. El objetivo de este estudio es analizar su relación con factores de riesgo y describir su manejo terapéutico. Métodos: Estudio retrospectivo, observacional y analítico. Se incluyeron resecciones colorrectales de coordinación por patología neoplásica maligna con anastomosis primaria, entre enero de 2015 y noviembre de 2018. Resultados: Ciento doce pacientes cumplieron con los criterios de inclusión. La tasa de DA fue 17% y la mortalidad 15%. El tamaño tumoral se asoció de forma estadísticamente significativa con un mayor riesgo de falla de sutura. Discusión: Nuestros resultados son similares a los reportados en la literatura, destacándose una alta proporción de DA tempranas y por lo tanto de reintervención y detransitación. Conclusiones: El manejo de la DA es un reto terapéutico y debe ajustarse a muchos parámetros, siendo uno de los más importantes la experiencia del cirujano. (AU)

Introduction: Anastomotic dehiscence (AD) is a complication of colorectal surgery that determines high morbidity and mortality and a worse oncological prognosis. The objective of this study is to analyze its relationship with risk factors and describe its therapeutic management. Material and Methods: Retrospective, observational and analytical study. Colorectal resections with primary anastomosis for malignant neoplastic pathology performed between January 2015 and November 2018 were included. Results: One hundred and twelve patients met the inclusion criteria. The AD rate was 17% and mortality 15%. Tumor size was statistically significantly associated with an increased risk of AF. Discussion: Our results are similar to those reported in the literature, highlighting a high proportion of early AD and therefore of re-intervention and intestinal diversion. Conclusions: The management of AD is a therapeutic challenge, and must be adjusted to many parameters, one of the most important being the surgeon's experience. (AU)

Effect of RYGB on Oxidative Stress in Adults: a 6-Year Follow-up Study.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is effective for weight loss but may have long-term effects on markers of oxidative stress (OS). The objective of this study is to evaluate the effect of bariatric surgery with RYGB on OS blood markers in a 72-month period after surgery. METHODS: A prospective cohort study was conducted with 20 patients before and after RYGB (months M0, M6, M12, M24, and M72) compared with a control group of 35 adults assessed only once. RESULTS: The body mass index (BMI) (45.71 ± 6.97 kg/m2) decreased by 38% from M0 to M24 (17.51 ± 5.50 kg/m2, p < 0.001), followed by a 12% increase from M24 to M72 (p < 0.001). Serum concentrations of vitamin E (adjusted for total cholesterol and triglycerides) and vitamin C increased throughout the study (p < 0.001). ß-carotene levels decreased progressively through to M72 (p = 0.008). Reduced glutathione (GSH) content and catalase (CAT) activity decreased at M6, M12, and M24, but no differences were found at M72 compared with M0. Concentrations of thiobarbituric acid reactive substances (TBARS) were lower M12 and M24 in comparison with baseline values (p < 0.001 and p = 0.004, respectively) but were similar to baseline values at 72 months (p = 0.114). CONCLUSIONS: GSH content, TBARS concentrations, and CAT activity returned to baseline values 72 months after RYGB, indicating the persistence of systemic OS, possibly attributable to weight regain and/or changes in the antioxidant defenses, such as the reduction in ß-carotene levels.

Tumor Budding en cáncer rectal. Relación entre la densidad de los brotes tumorales y otros factores pronósticos / Budding tumor in rectal cancer. Relationship between tumor outbreak density and other prognostic factors

Introducción: El budding tumor (BT) es la presencia de células tumorales aisladas o en pequeños grupos situadas en el frente de invasión del tumor. Su hallazgo en alto grado es un factor de mal pronóstico independiente del cáncer colorrectal. El objetivo de este trabajo es determinar si el grado de BT está asociado con otros factores pronósticos del cáncer rectal. Material y métodos: Se incluyen las resecciones oncológicas de recto en el período 2013-2017. Los casos se agruparon según la densidad en la formación de los BT en 3 grupos, los de grado bajo, intermedio y alto. Se utilizó como valor estadístico el cálculo del odds ratio (OR). Resultados: Se analizaron las piezas de resección de 27 pacientes (15 mujeres y 12 hombres) con una media de edad de 68,4 años (40-86). Se calculó el OR para invasión ganglionar, vascular y recidiva en función del grado de budding tumoral. Discusión: Se observó una tendencia a la presencia de factores histológicos de mal pronóstico en relación al budding de alto grado, si bien el bajo número de casos no permitió demostrarlo en este estudio. Conclusiones: El análisis del grado de tumor budding es reproducible y podría ayudar a identificar pacientes con cáncer rectal de peor pronóstico. (AU)

Introduction: Tumor budding (BT) is defined as isolated or small groups of neoplastic cells located at the invasive front of the tumor. High-grade BT is a poor prognostic factor in colorectal cancer. Objective: To determine if the degree of BT is associated with other prognostic factors in rectal cancer. Materials and methods: Rectal oncological resections during the 2013-2017 period were included. Cases were stratified according to the density in the formation of BT in 3 groups: low, intermediate and high. The calculation of the odds ratio (OR) was used as a statistical value. Results: The resection specimens of 27 patients (15 women and 12 men) with a mean age of 68.4 years (40-86) were analyzed. OR for node metastases, vascular invasion and relapse was calculated according to tumor budding grade. Discussion: High-grade tumor budding seems to associate with the presence of poor prognostic factors. However, it was not possible to demonstrate it because of the small sample size. Conclusions: Tumor budding is a reproducible marker and could help to identify rectal cancer patients with a worse prognosis. (AU)

Altered intestinal microbiota composition, antibiotic therapy and intestinal inflammation in children and adolescents with cystic fibrosis.

The aim of the present study was to evaluate the effect of cystic fibrosis and antibiotic therapy on intestinal microbiota composition and intestinal inflammation in children and adolescents. A cross-sectional controlled study was conducted with 36 children and adolescents: 19 in the cystic fibrosis group (CFG) and 17 in the control group (CG) matched for age and sex. The CFG was subdivided based on the use of antibiotic therapy (CFAB group) and non-use of antibiotic therapy (CFnAB group). The following data were evaluated: colonization, antibiotic therapy, mutation, breastfeeding, use of infant formula, type of delivery, introduction of solid foods, body mass index, fecal calprotectin and intestinal microbiota composition (fluorescence in situ hybridization). Intestinal inflammation evaluated by fecal calprotectin was significantly higher in the CFG (median: 40.80 µg/g, IQR: 19.80-87.10, p = 0.040) and CFAB group (median: 62.95 µg/g, IQR: 21.80-136.62, p = 0.045) compared to the CG (median: 20.15 µg/g, IQR: 16.20-31.00), and the Bacteroides, Firmicutes, Eubacterium rectale and Faecalibacterium prausnitzii were significantly decreased (p < 0.05) in the CFG compared to the CG, whereas the bacteria Clostridium difficile, Escherichia coli and Pseudomonas aeruginosa were significantly increased in the CFG (p < 0.05). The main differences were found between the CG and CFAB group for Eubacterium rectale (p = 0.006), Bifidobacterium (p = 0.017), Escherichia coli (p = 0.030), Firmicutes (p = 0.002), Pseudomonas aeruginosa (p < 0.001) and Clostridium difficile (p = 0.006). The results of this study confirm intestinal inflammation in patients with CF, which may be related to changes in the composition of the intestinal microbiota.

Associação do estado nutricional com função pulmonar e morbidade em crianças e adolescentes com fibrose cística: coorte de 36 meses / Association of nutritional status with lung function and morbidity in children and adolescents with cystic fibrosis: a 36-month cohort study

RESUMO Objetivo: Avaliar a associação entre estado nutricional, função pulmonar e morbidade em coorte de 36 meses de crianças e adolescentes com fibrose cística (FC). Métodos: Coorte prospectiva de 36 meses, com crianças e adolescentes com FC e idade entre 1 e 15 anos. No tempo inicial, o estado nutricional foi determinado a partir dos indicadores: peso-para-estatura e índice de massa corporal-para-idade, para crianças <2 anos e ≥2 anos, respectivamente, e classificado em: falência nutricional, risco nutricional e estado nutricional aceitável; também foi determinado por meio do percentil 50°, de acordo com a curva de crescimento da World Health Organization (WHO). A função pulmonar foi avaliada pelo volume expiratório forçado no primeiro segundo (VEF1). A morbidade foi determinada pela presença de infecção e hospitalização por exacerbação pulmonar. Foi calculado risco relativo (RR) e intervalo de confiança (IC95%), considerando significante p<0,05. Resultados: Foram avaliadas 38 crianças e adolescentes (mediana de idade 3,8 anos). Os pacientes classificados em falência nutricional no início do estudo mostraram um RR de 5,00 (IC95% 1,49; 16,76) para o comprometimento da função pulmonar após 36 meses. Aqueles classificados abaixo do percentil 50° apresentaram RR de 4,61 (IC95% 0,89; 23,81) para o desfecho. O estado nutricional não foi fator de risco para morbidade. Conclusões: O déficit nutricional esteve associado ao comprometimento da função pulmonar, mas não com a morbidade em crianças e adolescentes com FC.

ABSTRACT Objective: To evaluate the association between nutritional status, lung function and morbidity in a 36-month cohort in children and adolescents with cystic fibrosis. Methods: Prospective cohort of children and adolescents with cystic fibrosis aged 1-15 years. At the baseline, the nutritional status was determined by weight-for-height and body mass index-for-age for children <2 years and ≥2 years, respectively, and classified as: nutritional failure, nutritional risk and acceptable; and by the 50th percentile, according to the World Health Organization (WHO) growth charts. Lung function was assessed by forced expiratory volume in one second (FEV1). Morbidity was determined by the presence of infection and hospitalization by pulmonary exacerbation. Risk ratio and 95% confidence interval (95%CI) were calculated, being significant when p<0.05. Results: We evaluated 38 children and adolescents (median age 3.8 years). Patients that were classified as having nutritional failure at baseline had a RR of 5.00 (95%CI 1.49; 16.76) to present impaired lung function after 36 months. Those classified bellow the 50th percentile had a RR of 4.61 (95%CI 0.89; 23.81) to present the same outcome. Nutritional status was not a risk factor for morbidity in this cohort. Conclusions: Nutritional deficit was associated with impaired lung function, but not with morbidity in children and adolescents with cystic fibrosis.

C-reactive protein/albumin ratio is associated with lung function among children/adolescents with cystic fibrosis: a three-year longitudinal study

ABSTRACT BACKGROUND: Chronic lung infections, inflammation and depletion of nutritional status are considered to be prognostic indicators of morbidity in patients with cystic fibrosis. The aim of this study was to investigate the association between inflammatory markers and lung function, nutritional status and morbidity among children/adolescents with cystic fibrosis. DESIGN AND SETTINGS: Prospective three-year longitudinal study conducted in an outpatient clinic in southern Brazil. METHODS: Children/adolescents aged 1-15 years with cystic fibrosis were enrolled. Nutritional status was determined from weight-to-length and body mass index-to-age z-scores and was classified as acceptable, at risk or nutritional failure. Tumor necrosis factor-α, interleukin-1β, myeloperoxidase, C-reactive protein and C-reactive protein/albumin ratio were analyzed. Lung function was evaluated based on the forced expiratory volume in the first second and morbidity according to the number of hospitalizations for pulmonary exacerbation and infections by Pseudomonas aeruginosa. Lung function, nutritional status and morbidity were the outcomes. Odds ratios and 95% confidence intervals were to evaluate the effect of baseline inflammatory markers on the clinical outcomes after three years of follow-up and p-values < 0.05 were considered significant. RESULTS: We evaluated 38 children/adolescents with cystic fibrosis: 55% female; median age (with interquartile range), 3.75 years (2.71-7.00). Children/adolescents with high C-reactive protein/albumin ratio at baseline had odds of 18 (P = 0.018) of presenting forced expiratory volume in the first second ≤ 70% after three years. The other inflammatory markers were not associated with the outcomes. CONCLUSION: C-reactive protein/albumin ratio was associated with forced expiratory volume in the first second ≤ 70% after three years.

A resistance exercise program improves functional capacity of patients with psoriatic arthritis: a randomized controlled trial.

The objective of this study is to assess the effectiveness of resistance training in patients with psoriatic arthritis (PsA). The study is a randomized controlled trial with 41 patients aged between 18 and 65 years with diagnosis of psoriatic arthritis (PsA). The patients were randomized into the following: intervention group (IG) and control group (CG). The IG underwent resistance exercise twice a week, for 12 weeks. The CG remained with the conventional drug therapy. The outcome measurements were the following: BASFI and HAQ-S for functional capacity, one maximum repetition test (1RM) for muscle strength, SF-36 questionnaire for general quality of life, and BASDAI and DAS-28 for disease activity. The evaluations were done by a blinded evaluator at baseline (T0) after 6 (T6) and 12 weeks (T12). At baseline, the groups were homogeneous regarding clinical and demographic characteristics. The IG significantly improved functional capacity measured by HAQ-S and disease activity measured by BASDAI, compared to CG, at week 12. Regarding quality of life, the IG improved the domains "pain" and "general health status" compared to CG (p < 0.05). There was improvement in muscular strength in almost all exercises in IG, except in the exercise for biceps. However, there were statistical differences between groups only on exercise "leg extension" in IG compared to CG. Resistance training is effective in improving functional capacity, disease activity, and quality of life of patients with psoriatic arthritis. The clinical improvements were not coupled to significant changes in muscular strength.

Effect of synbiotic supplementation in children and adolescents with cystic fibrosis: a randomized controlled clinical trial.

BACKGROUND/OBJECTIVES: Cystic fibrosis (CF) is characterized by excessive activation of immune processes. The aim of this study was to evaluate the effect of synbiotic supplementation on the inflammatory response in children/adolescents with CF. SUBJECTS/METHODS: A randomized, placebo-controlled, double-blind, clinical-trial was conducted with control group (CG, n = 17), placebo-CF-group (PCFG, n = 19), synbiotic CF-group (SCFG, n = 22), PCFG negative (n = 8) and positive (n = 11) bacteriology, and SCFG negative (n = 12) and positive (n = 10) bacteriology. Markers of lung function (FEV1), nutritional status [body mass index-for age (BMI/A), height-for-age (H/A), weight-for-age (W/A), upper-arm fat area (UFA), upper-arm muscle area (UMA), body fat (%BF)], and inflammation [interleukin (IL)-12, tumor necrosis factor-alpha (TNF-α), IL-10, IL-6, IL-1ß, IL-8, myeloperoxidase (MPO), nitric oxide metabolites (NOx)] were evaluated before and after 90-day of supplementation with a synbiotic. RESULTS: No significance difference was found between the baseline and end evaluations of FEV1 and nutricional status markers. A significant interaction (time vs. group) was found for IL-12 (p = 0.010) and myeloperoxidase (p = 0.036) between PCFG and SCFG, however, the difference was not maintained after assessing the groups individually. NOx diminished significantly after supplementation in the SCFG (p = 0.030). In the SCFG with positive bacteriology, reductions were found in IL-6 (p = 0.033) and IL-8 (p = 0.009) after supplementation. CONCLUSIONS: Synbiotic supplementation shown promise at diminishing the pro-inflammatory markers IL-6, IL-8 in the SCFG with positive bacteriology and NOx in the SCFG in children/adolescents with CF.

Associations Between Caries Experience, Nutritional Status, Oral Hygiene, and Diet in a Multigenerational Cohort.

PURPOSE: To assess intergenerational associations between dental caries and nutritional status, oral hygiene habits, and diet. METHODS: A cross-sectional study was conducted with three generations of 54 families. Inclusion criteria were senior citizens with an adult son/daughter who also had a child (five to 12 years old). Dental caries was assessed using the decayed, missing, filled, primary teeth (dmft) and permanent teeth (DMFT) indexes. Nutritional status was evaluated using the body mass index (BMI), waist circumference, and percentage of body fat. Dietary habits, oral hygiene habits, and socioeconomic status were evaluated using a structured questionnaire. RESULTS: Children/adolescents with higher BMI had a lower dmft/DMFT index, and those who never or almost never consumed fruits and vegetables as snacks had a higher dmft/ DMFT index. When parents did not visit the dentist regularly, children/adolescents had more teeth affected by dental caries. When parents consumed sugar two or more times between meals, the number of affected teeth in children/adolescents increased. CONCLUSIONS: When children/ adolescents had a higher body mass index and they consumed fruits/vegetables as snacks more frequently, their caries experiences were lower. When their parents' did not visit the dentist regularly and they consumed sugar between meals more frequently, the children's caries experiences were higher.

Nutrition Status Parameters and Hydration Status by Bioelectrical Impedance Vector Analysis Were Associated With Lung Function Impairment in Children and Adolescents With Cystic Fibrosis.

BACKGROUND: (1) To compare nutrition and hydration status between a group of children/adolescents with cystic fibrosis (CFG; n = 46; median age, 8.5 years) and a control group without cystic fibrosis (CG). (2) To examine the association of nutrition and hydration status with lung function in the CFG. MATERIAL AND METHODS: A cross-sectional study. Nutrition screening, anthropometric parameters, and bioelectrical impedance analysis (BIA) were assessed. The z scores for body mass index for age, height for age, mid upper arm circumference, triceps and subscapular skinfold thickness, mid upper arm muscle area, resistance/height, and reactance/height were calculated. Bioelectrical impedance vector analysis was conducted. Forced expiratory volume in 1 second <80% was considered lung function impairment. An adjusted logistic regression was applied (P < .05). RESULTS: In the CFG, lung function impairment was observed in 51.1%. All anthropometric parameters were lower, and the mean z-resistance/height and z-reactance/height were higher in the CFG (P < .05) compared with the CG. In the CFG, 43% were severely/mildly dehydrated, while none were in the CG (P = .007). In the CFG, there was an association between high nutrition risk-via nutrition screening (odds ratio [OR], 22.28; P < .05), lower values of anthropometric parameters, higher z-resistance/height (OR, 2.23; P < .05) and z-reactance/height (OR, 1.81; P < .05), and dehydration (OR, 4.94; P < .05)-and lung function impairment. CONCLUSIONS: The CFG exhibited a compromised nutrition status assessed by anthropometric and BIA parameters. Nutrition screening, anthropometric and BIA parameters, and hydration status were associated with lung function.

Translation, cultural adaptation and reproducibility of the Oxford Shoulder Score questionnaire for Brazil, among patients with rheumatoid arthritis / Tradução, adaptação cultural e reprodutibilidade do questionário Oxford Shoulder Score para o Brasil em pacientes com artrite reumatoide

ABSTRACT CONTEXT AND OBJECTIVE Although shoulder questionnaires validated for Brazil do exist, none of them are aimed at populations with rheumatic disease. We believe that the Oxford Shoulder Score (OSS) may be useful in this population. The objective of this study was to translate the OSS, adapt it to Brazilian culture and test its reproducibility. DESIGN AND SETTING Validation study conducted in university outpatient clinics. METHODS The OSS was translated into Portuguese by two English teachers and was then retranslated into English by two native English teachers. These translations were reviewed by a committee to establish the version of OSS-Brazil to be administered to 30 patients with rheumatoid arthritis (RA) and shoulder pain, in order to test the cultural adaptation. The validity and reproducibility was tested among another 30 patients with RA and shoulder pain, of both genders and aged 18 to 65 years. The internal consistency and reproducibility were analyzed. The following instruments were evaluated: OSS-Brazil; a numerical scale for shoulder pain; DASH; HAQ and SF-36. RESULTS The internal consistency was 0.957 and the intra and inter-rater reproducibility was 0.917 and 0.861, respectively. A high level of correlation was found between OSS-Brazil and the following: HAQ (-0.663), DASH (-0.731) and the SF-36 domains of functional capacity (0.589), physical aspects (0.507), pain (0.624), general state of health (0.444), vitality (0.634) and mental health (0.578). CONCLUSION OSS-Brazil was successfully translated and adapted, and this version exhibited good internal consistency, reliability and construct validity.

RESUMO CONTEXTO E OBJETIVO Apesar de existirem questionários de ombro validados para o Brasil, nenhum deles é voltado para a população com doenças reumáticas. Acreditamos que o Oxford Shoulder Score (OSS) possa ser útil nessa população. O objetivo deste estudo foi traduzir, adaptar à cultura brasileira e testar a reprodutibilidade do OSS. TIPO DE ESTUDO E LOCAL Estudo de validação realizado nos ambulatórios da universidade. MÉTODOS Foi realizada a tradução para o português por dois professores de inglês e depois a retradução para o inglês por dois professores nativos da língua inglesa. Essas traduções foram revisadas por um comitê para estabelecer a versão do OSS-Brasil, que foi aplicada em 30 pacientes com artrite reumatoide (AR) e dor no ombro para testar a adaptação cultural. A validade e a reprodutibilidade foram testadas em outros 30 pacientes com AR e dor no ombro de ambos os gêneros com idade entre 18 a 65 anos. Foram analisadas a consistência interna e a reprodutibilidade. Foram avaliados os seguintes instrumentos: OSS-Brasil; escala numérica de dor no ombro; DASH; HAQ e SF-36. RESULTADOS A consistência interna foi 0,957 e a reprodutibilidade intra-avaliador e interavaliador foi 0,917 e 0,861, respectivamente. Foi observado alto nível de correlação do OSS-Brasil com HAQ (-0,663), DASH (-0,731) e os domínios do SF-36: capacidade funcional (0,589); aspectos físicos (0,507); dor (0,624); estado geral de saúde (0,444); vitalidade (0,634); saúde mental (0,578). CONCLUSÃO O OSS-Brasil foi traduzido e adaptado com sucesso, com boa consistência interna, confiabilidade e validade de construção.

Persistence of the benefit of an antioxidant therapy in children and teenagers with Down syndrome.

This study examined the effect of an antioxidant intervention in biomarkers of inflammation and oxidative stress (OS) in the blood of Down syndrome (DS) children and teenagers during four different stages. A control group was composed by healthy children (n=18), assessed once, and a Down group composed by DS patients (n=21) assessed at the basal period (t0), as well as after 6 months of antioxidant supplementation (t1), after 12 months (after interruption of the antioxidant intervention for 6 months) (t2), and again after further 6 months of antioxidant supplementation (t3). Biomarkers of inflammation (myeloperoxidase activity - MPO and levels of IL-1ß and TNF-α) and OS (thiobarbituric acid reactive substances - TBARS, protein carbonyls - PC), reduced glutathione (GSH), uric acid (UA) and vitamin E levels, as well as antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GPx), glutathione reductase (GR), glutathione-S-transferase (GST) and gamma-glutamyltransferase (GGT) activities, were measured after each period. After the antioxidant supplementation, the activities of SOD, CAT, GPx, GR, GGT and MPO were downregulated, while TBARS contents were strongly decreased, the contents of GSH and vitamin E were significantly increased, and no changes in G6PD and GST activity as well as in UA and PC levels were detected. After the interruption of the antioxidant therapy for 6 months, DS patients showed elevated GPx and GGT activities and also elevated UA and TBARS levels. No changes in SOD, CAT, GR, GST, G6PD and MPO activities as well as in GSH, vitamin E, PC, TNF-α and IL-1ß levels were detected. The results showed that the antioxidant intervention persistently attenuated the systemic oxidative damage in DS patients even after a relatively long period of cessation of the antioxidant intervention.

Perceived purchase of healthy foods is associated with regular consumption of fruits and vegetables.

OBJECTIVE: To identify healthy food (HF) purchase habits and intake of fruits and vegetables (FV) in parents responsible for grocery shopping for their families. METHODS: Survey with mothers and fathers (n = 216) of children aged 7-10 years in Brazil. RESULTS: Grocery purchases occurred mostly at supermarkets. Purchase of HF was considered to be frequent by 80% of parents, who cited FV as main examples of HF. The more frequent the reported purchase was of HF, the higher was the prevalence of regular consumption of FV (P = .002). Only 34% of respondents reported weekly intakes that could be classified as regular. CONCLUSIONS AND IMPLICATIONS: Perceived frequent shopping for healthy foods was positively associated with regular consumption of FV but a gap between perception and behavior was identified. Nutrition education strategies need to go beyond a merely informative role and take consumers' opinions and points of view into consideration to become truly effective.

Influence of inflammatory response, infection, and pulmonary function in cystic fibrosis.

AIMS: Recurrent infections and activation of the inflammatory response affect the prognosis of cystic fibrosis (CF). We investigated the relationship between inflammatory response, infection, and pulmonary function in CF. MAIN METHODS: A clinical-cross-sectional study was conducted with 86 subjects: control group (CG, n=31, the same age and sex of the CF group), and CF group (CFG, n=55, age: 1-16 years), further distributed into CFG negative or positive bacteriology (CFGB(-)/CFGB(+)), and CFG negative or positive Pseudomonas aeruginosa (CFGPa(-)/CFGPa(+)). Using the Wald test, multiple linear regression (95% confidence interval) was performed between CG and CFG, and between CG and each of the CF subgroups (CFGB(-)/CFGB(+) and CFGPa(-)/CFGPa(+)). The inflammatory markers evaluated were myeloperoxidase (MPO), adenosine deaminase (ADA) activities, interleukin-1beta (IL-1ß), tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), nitric oxide metabolites (NOx) levels, and total and differential leukocyte counts. KEY FINDINGS: After adjusting for sex and age, CFG compared to CG revealed an increase of MPO, IL-1ß (P<0.001 in all subgroups), and CRP: CFG (P=0.002), CFGB(-) (P=0.007), CFGB(+) (P=0.009), CFGPa(-) (P=0.004) and CFGPa(+) (P=0.020). NOx (P=0.001, P<0.001), leukocytes (P=0.002, P=0.001), and neutrophils (P=0.003, P<0.001) were increased in CFGB(+) and CFGPa(+), respectively. A negative correlation between FEV1 and leukocytes (P=0.008) and FEV1 and neutrophils (P=0.031) resulted in CFG. SIGNIFICANCE: The inflammatory response characterized by the increase of MPO, IL-1ß, and CRP is determinant for CF. Also leukocytosis due to neutrophilia determines the pulmonary function deficiency in this disease.
