Efeito da compressão isquémica no ponto gatilho do trapézio superior no controlo motor do ombro

Introdução: A síndrome dolorosa miofascial (SDM) é uma das causas mais comuns de dor com origem músculo-esquelética, devendo-se sobretudo à existência de pontos gatilho (PG) miofasciais. O PG no músculo trapézio superior (TS), sob a sua forma latente, tem repercussões no equilíbrio muscular do complexo articular do ombro. A intervenção sobre este PG, através da compressão isquémica poderá ter benefícios no próprio músculo e no controlo motor do complexo articular do ombro. Objetivos: Pretende-se estudar a influência da intervenção no PG latente do músculo TS no controlo motor do ombro, analisando as alterações ao nível do timing de ativação muscular, das sequências em que o músculos ativam e do nível de atividade muscular ao longo do movimento. Métodos: Foi realizado um estudo do tipo experimental, aleatório e controlado com uma amostra dividida em dois grupos, grupo experimental (n=15) e grupo controlo (n=14). No grupo experimental foi realizada a técnica de compressão isquémica no PG do TS e no grupo controlo um procedimento placebo. Antes e após a intervenção foi recolhida a atividade eletromiográfica dos músculos grande dentado (GD), infra-espinhoso (IE), deltóide médio (DM), trapézio superior (TS) e trapézio inferior (TI), assim como os dados cinemáticos, durante o movimento de elevação do ombro no plano da omoplata. Foi analisado o timing de ativação muscular, as sequências de ativação e o nível de ativação muscular ao longo do arco de movimento, através da magnitude normalizada à contração muscular voluntária máxima. Resultados: Foi observada uma maior pré ativação do músculo GD, no grupo experimental após a intervenção (p=0,025) relativamente ao primeiro momento de avaliação. É de notar que após a intervenção, no GE, todos os músculos passaram a ativar no período típico dos ajustes posturais antecipatórios, não tendo o mesmo sido observado no grupo de controlo. Após a técnica, 37% dos indivíduos do grupo experimental passaram a ativar o GD em primeiro lugar, quando apenas um sujeito o fazia antes da intervenção. Destaca-se também um predomínio de 32% nas últimas posições, após a técnica, dos músculos trapézio superior e inferior. No GC não se verifica nenhuma tendência após a intervenção. Foram ainda observadas diferenças estatisticamente significativas entre os grupos nos arcos de movimento onde foi atingido 20% da contração isométrica voluntária máxima (CMVI) nos músculos DM (p=0,002), na primeira avaliação, e IE (p=0,021), após a intervenção, com um atraso da ativação do IE para valores superiores a 20% da CMVI. Conclusão: A compressão isquémica reflete-se na antecipação da atividade do músculo GD e num atraso do aumento da magnitude da atividade do IE para valores moderados,

The Effect of Long-Chain Polyunsaturated Fatty Acids Intake During Pregnancy on Adiposity of Healthy Full-Term Offspring at Birth

OBJECTIVE: The adjusted effect of long-chain polyunsaturated fatty acid (LCPUFA) intake during pregnancy on adiposity at birth of healthy full-term appropriate-for-gestational age neonates was evaluated. STUDY DESIGN: In a cross-sectional convenience sample of 100 mother and infant dyads, LCPUFA intake during pregnancy was assessed by food frequency questionnaire with nutrient intake calculated using Food Processor Plus. Linear regression models for neonatal body composition measurements, assessed by air displacement plethysmography and anthropometry, were adjusted for maternal LCPUFA intakes, energy and macronutrient intakes, prepregnancy body mass index and gestational weight gain. RESULT: Positive associations between maternal docosahexaenoic acid intake and ponderal index in male offspring (β=0.165; 95% confidence interval (CI): 0.031-0.299; P=0.017), and between n-6:n-3 LCPUFA ratio intake and fat mass (β=0.021; 95% CI: 0.002-0.041; P=0.034) and percentage of fat mass (β=0.636; 95% CI: 0.125-1.147; P=0.016) in female offspring were found. CONCLUSION: Using a reliable validated method to assess body composition, adjusted positive associations between maternal docosahexaenoic acid intake and birth size in male offspring and between n-6:n-3 LCPUFA ratio intake and adiposity in female offspring were found, suggesting that maternal LCPUFA intake strongly influences fetal body composition.

Índice de massa corporal e ganho ponderal gestacional como fator determinante do peso ao nascer do recém-nascido

RESUMO - Introdução: A literatura aponta que a gravidez é um período do ciclo reprodutivo associado com o excesso de peso, que se tem tornado um problema de saúde pública em ascensão. Na verdade, evidências sugerem que o excessivo peso pré-gestacional e o ganho ponderal excessivo estão associados a um peso elevado do RN. Objetivos: Relacionar o IMC antes da conceção e o ganho ponderal durante a gestação com o PN do RN. Métodos: Foi realizado um estudo epidemiológico, analítico, observacional e transversal, com uma amostra de cento e três mães e respetivos RNs, de termo, saudáveis e de gravidez única, da Unidade de Obstetrícia do Hospital Beatriz Ângelo. Estas foram recrutadas entre novembro de 2012 e março de 2013 inclusive. Para tal, foram recolhidos dados clínicos e outras informações relativas à gravidez e parto, nomeadamente o PN, através do sistema informático. Resultados: Após a análise dos resultados, constatou-se que mães com IMC superior a 25 antes da gravidez apresentam ganho ponderal durante a gravidez acima dos valores recomendados (47,2%). A prevalência de macrossomia e baixo peso ao nascer também foi maior em mães com excesso de peso (p=0,021), tal como de PIG e GIG (p=0,004). Observando a influência do ganho ponderal verificou-se que 9,5% (n=4) das mães com ganho ponderal excessivo tiveram RN com elevado peso ao nascer, enquanto 14,3% (n=4) das mães com ganho ponderal abaixo do recomendado tiveram RN com baixo peso ao nascer (p=0,018). Verificou-se também que o tempo de gestação é maior em mães com ganho ponderal acima do recomendado (p=0,024), e que este fator está positivamente associado com o PN (r=0,218; p=0,029), comprimento (r=0,221; p=0,027) e PC (r=0,249; p=0,012) do RN. No que se refere às correlações, encontrou-se uma correlação positiva moderada entre os fatores maternos (peso antes de engravidar; IMC pré-gestacional; e ganho ponderal) e o PN. Discussão/Conclusão: Desta forma, podemos concluir que tanto o excesso de peso pré-gestacional como o ganho de peso inadequado durante a gestação têm implicações diretas no peso do recém-nascido, nomeadamente aumentando o risco de macrossomia fetal.

Sleep disorders in boys with Duchenne muscular dystrophy.

Aim:  Determine the frequency and predictors of sleep disorders in boys with Duchenne Muscular Dystrophy (DMD). Method:  Cross-sectional study by postal questionnaire. Sleep disturbances were assessed using the Sleep Disturbance Scale for Children (validated on 1157 healthy children). A total sleep score and six sleep disturbance factors representing the most common sleep disorders were computed. Potential associations between pathological scores and personal, medical and environmental factors were assessed. Results:  Sixteen of 63 boys (25.4%) had a pathological total sleep score compared with 3% in the general population. The most prevalent sleep disorders were disorders of initiating and maintaining sleep (DIMS) 29.7%, sleep-related breathing disorders 15.6% and sleep hyperhydrosis 14.3%. On multivariate analysis, pathological total sleep scores were associated with the need to be moved by a carer (OR = 9.4; 95%CI: 2.2-40.7; p = 0.003) and being the child of a single-parent family (OR = 7.2; 95%CI: 1.5-35.1; p = 0.015) and DIMS with the need to be moved by a carer (OR = 18.0; 95%CI: 2.9-110.6; p = 0.002), steroid treatment (OR = 7.7; 95%CI: 1.4-44.0; p = 0.021) and being the child of a single-parent family (OR = 7.0; 95%CI: 1.3-38.4; p = 0.025). Conclusion:  Sleep disturbances are frequent in boys with DMD and are strongly associated with immobility. Sleep should be systematically assessed in DMD to implement appropriate interventions.

Mise en place d'un programme de prévention et de prise en charge du diabète en Suisse: le point de vue des patients et des professionnels de la santé [Implementation of a diabetes disease management program in Switzerland: patients' and healthcare professionals' point of view].

BACKGROUND: A reorganization of healthcare systems is required to meet the challenge of the increasing prevalence of chronic diseases, e.g. diabetes. In North-America and Europe, several countries have thus developed national or regional chronic disease management programs. In Switzerland, such initiatives have only emerged recently. In 2010, the canton of Vaud set up the "Diabetes Cantonal Program", within the framework of which we conducted a study designed to ascertain the opinions of both diabetic patients and healthcare professionals on the elements that could be integrated into this program, the barriers and facilitators to its development, and the incentives that could motivate these actors to participate. METHODS: We organized eight focus-groups: one with diabetic patients and one with healthcare professionals in the four sanitary areas of the canton of Vaud. The discussions were recorded, transcribed and submitted to a thematic content analysis. RESULTS: Patients and healthcare professionals were rather in favour of the implementation of a cantonal program, although patients were more cautious concerning its necessity. All participants envisioned a set of elements that could be integrated to this program. They also considered that the program could be developed more easily if it were adapted to patients' and professionals' needs and if it used existing structures and professionals. The difficulty to motivate both patients and professionals to participate was mentioned as a barrier to the development of this program however. Quality or financial incentives could therefore be created to overcome this potential problem. CONCLUSION: The identification of the elements to consider, barriers, facilitators and incentives to participate to a chronic disease management program, obtained by exploring the opinions of patients and healthcare professionals, should favour its further development and implementation.

Efficacy and safety of certolizumab pegol induction therapy in an unselected Crohn's disease population: results of the FACTS survey.

Background: Switzerland was the first country to approve certolizumab pegol (Cimzia, CZP) for the treatment of patients with moderate to severe Crohn's disease (CD) in September 2007. This phase IV study aimed to evaluate the efficacy and safety of CZP in a Swiss multicenter cohort of practice-based patients. Methods: Baseline and Week 6 evaluation questionnaires were sent to all Swiss gastroenterologists in hospitals and private practices. Disease activity was assessed with the Harvey-Bradshaw Index (HBI) and adverse events were evaluated according to WHO guidelines. Results: Fifty patients (31 women, 19 men) were included; 56% had complicated disease (stricture or fistula) and 52% had undergone prior CD-related surgery. All patients. had prior exposure to systemic steroids, 96% to immunomodulators, 78% to infliximab, and 50% to adalimumab. A significant decrease in HBI was observed at Week 6 (versus Week 0) following induction therapy with CZP 400 mg subcutaneously at Weeks 0, 2, and 4 (12.6 +/- 4.7 Week 0 versus 6.2 +/- 4.4 Week 6, P < 0.001). Response and remission rates at Week 6 were 54% and 40%, respectively. We identified 8/11 CD patients undergoing a 50% fistula response (P = 0.021). The frequency of adverse drug reactions attributed to CZP was 6%. CZP was continued in 80% of patients beyond Week 6. Conclusions: In a population of CD patients with complicated disease behavior, CZP induced a response and remission in 54% and 40% of patients, respectively. This series provides the first evidence of the effectiveness of CZP in perianal fistulizing CD.

Characteristics of infections associated with external ventricular drains of cerebrospinal fluid.

OBJECTIVES: Manifestations of external ventricular drain (EVD) - associated infections overlap with those of the underlying neurosurgical conditions. We analyzed characteristics of EVD-associated infections. METHODS: We included patients aged ≥18 years with EVD-associated infections from 1997 to 2008, using modified CDC criteria for nosocomial infections. Hospital charts were reviewed retrospectively and the in-hospital outcome was evaluated. RESULTS: Forty-eight patients with EVD-associated infections were included (median age, 52 years, range 20-74 years). The median EVD-indwelling time was 7 days (range, 1-39 days) and EVD-associated infection occurred 6 days after insertion (range, 1-17 days). In 23% of patients, meningitis occurred 1-10 days after EVD removal. Fever >38 °C was present in 79% of patients, but Glasgow Coma Scale (GCS) scores were reduced in only 29%, and headache, vomiting and/or neck stiffness were present in only 31%. The median cerebrospinal fluid (CSF) leukocyte count was higher at onset of EVD-associated infection than at EVD insertion (175 × 10(6)/l versus 46 × 10(6)/l, p = 0.021), but other CSF parameters did not differ significantly. The most commonly implicated organisms were coagulase-negative staphylococci (63%) and Propionibacterium acnes (15%). CONCLUSIONS: Fever and increased CSF leukocytes should raise the suspicion of EVD-associated infection, which may occur up to 10 days after removal of EVD.

Admissions of patients with alcohol intoxication in the Emergency Department: a growing phenomenon.

QUESTION UNDER STUDY: To investigate the change over time in the number of ED admissions with positive blood alcohol concentration (BAC) and to evaluate predictors of BAC level. METHODS: We conducted a single site retrospective study at the ED of a tertiary referral hospital (western part of Switzerland) and obtained all the BAC performed from 2002 to 2011. We determined the proportion of ED admissions with positive BAC (number of positive BAC/number of admissions). Regression models assessed trends in the proportion of admissions with positive BAC and the predictors of BAC level among patients with positive BAC. RESULTS: A total of 319,489 admissions were recorded and 20,021 BAC tests were performed, of which 14,359 were positive, divided 34.5% female and 65.5% male. The mean (SD) age was 41.7(16.8), and the mean BAC was 2.12(1.04) permille (g of ethanol/liter of blood). An increase in the number of positive BAC was observed, from 756 in 2002 to 1,819 in 2011. The total number of admissions also increased but less: 1.2 versus 2.4 times more admissions with positive BAC. Being male was independently associated with a higher (+0.19 permille) BAC, as was each passing year (+0.03). A significant quadratic association with age indicated a maximum BAC at age 53. CONCLUSION: We observed an increase in the percentage of admissions with positive BAC that was not limited to younger individuals. Given the potential consequences of alcohol intoxication, and the large burden imposed on ED teams, communities should be encouraged to take measures aimed at reducing alcohol intoxication.

Características de la estructura especiológica del subsistema demersal durante el invierno de 1996

La fauna acompañante en la pesca de arrastre de la merluza, varía en su composición especiológica, distribución batimétrica, latitudinal y estacional de acuerdo a las condiciones de medio marino. Para el invierno de 1996, se analiza la ocurrencia de la fauna marina de aguas tropicales y templadas, entre Punta Capones y el Puerto de Chimbote durante el Crucero de Evaluación de la Merluza BIC SNP-1 9607-08, empleando una red de fondo tipo Granton 400/127. Se capturaron 69 especies: 56 peces, 4 crustáceos, 5 moluscos, un equinodermo, un cnidario y un cordado. La mayor riqueza íctica se encontró al norte del paralelo 6°S. La captura total en el área estudiada fue de 20.021,43 kg de peces (99%) y 211,24 kg (1%) de invertebrados. La merluza Merluccius gayi peruanus, destaca por su abundancia y frecuencia, se capturaron 18.501,52 kg (91,4% del volumen total). Entre los elasmobranquios, destaca la "raya águila" Myliobatis chilensis y dentro de los teleósteos (peces óseos), los Pisciformes con 19 spp., siendo la familia Sciaenidae la mejor representada con 7 especies.

Localización, distribución y concentración de langostinos rojos de profundidad. Crucero BIC Humboldt 9607-08

El crucero "Localización, Concentración y Distribución de los Langostinos Rojos de Profundidad", se desarrolló entre el 18 de julio y el 06 de agosto de 1996, utilizando una red de arrastre tipo Gran ton, modelo 400/130. Se exploró el área comprendida entre Puerto Pizarro y Huarmey a profundidades entre 254 y 1 021 m. A partir de la información obtenida en el rastreo acústico, realizado en el área citada y del conocimiento de la existencia de dos biocenosis en la zona arquibentónica, una al norte y la otra al sur del Banco de Máncora, se determinó realizar el estudio sistemático y bioecológico del recurso objetivo, en el área comprendida entre 03°24' a 04°05'S y 81"00' a 81"25'W. • En esta área de evaluación, la captura estuvo constituida por peces (86,92%), crustáceos (8,04 %), moluscos (2,78%), equinodermos (1,20%), onidarios (1 ,00%), poríferos (0,03%), anélidos (0,03%), briozoarios (0,00 1%) y sipuncúlidos (0,004 %). Se registraron 38 especies de crustáceos, de los cuales 7 constituyeron los denominados langostinos de profundidad: ifeterocarpus vicarius, Haliporoides" diomedeae, Nematocarcinus agassizii, Heterocarpus hostilis, Psathyrocaris fragilis, Plesionika trispinus y Pasiphaea magna. Los más importantes langostinos rojos de profundidad se presentaron desde los 08° 18.20' S hasta los 03"32.11' S, principalmente al sur del Banco de Máncora, a profundidades entre 382 y 1 021 m. La densidad media (t/mn2) del total de langostinos rojos de profundidad, para el área de evaluación estuvo comprendida entre 0,0017 y 0,420 t/mn 2• Se determinó una profundización de los langostinos rojos fuera de su área habitual, asociado a un desplaza­miento de la mínima de oxígeno hacia mayores profundidades. Esto determinó poca disponibilidad de los principales langostinos rojos de profundidad. Se destaca la mayor frecuencia de la "gamba" Haliporoides diomedeae entre 0,2 a 1,6 ml/l de oxígeno disuelto, con sus mayores densidades entre 0,8 a 1,6 ml/l. El "camarón naylon" Heterocarpus vicarius, mostró las mayores concentraciones a menores tenores de oxígeno (0, 17 a 0,25 ml/1). Se establecieron relaciones biométricas de las principales especies de langostinos rojos de profundidad.

Preoperative nutritional screening by the specialist instead of the nutritional risk score might prevent excess nutrition: a multivariate analysis of nutritional risk factors.

BACKGROUND: The aim of the current study was to assess whether widely used nutritional parameters are correlated with the nutritional risk score (NRS-2002) to identify postoperative morbidity and to evaluate the role of nutritionists in nutritional assessment. METHODS: A randomized trial on preoperative nutritional interventions (NCT00512213) provided the study cohort of 152 patients at nutritional risk (NRS-2002 ≥3) with a comprehensive phenotyping including diverse nutritional parameters (n=17), elaborated by nutritional specialists, and potential demographic and surgical (n=5) confounders. Risk factors for overall, severe (Dindo-Clavien 3-5) and infectious complications were identified by univariate analysis; parameters with P<0.20 were then entered in a multiple logistic regression model. RESULTS: Final analysis included 140 patients with complete datasets. Of these, 61 patients (43.6%) were overweight, and 72 patients (51.4%) experienced at least one complication of any degree of severity. Univariate analysis identified a correlation between few (≤3) active co-morbidities (OR=4.94; 95% CI: 1.47-16.56, p=0.01) and overall complications. Patients screened as being malnourished by nutritional specialists presented less overall complications compared to the not malnourished (OR=0.47; 95% CI: 0.22-0.97, p=0.043). Severe postoperative complications occurred more often in patients with low lean body mass (OR=1.06; 95% CI: 1-1.12, p=0.028). Few (≤3) active co-morbidities (OR=8.8; 95% CI: 1.12-68.99, p=0.008) were related with postoperative infections. Patients screened as being malnourished by nutritional specialists presented less infectious complications (OR=0.28; 95% CI: 0.1-0.78), p=0.014) as compared to the not malnourished. Multivariate analysis identified few co-morbidities (OR=6.33; 95% CI: 1.75-22.84, p=0.005), low weight loss (OR=1.08; 95% CI: 1.02-1.14, p=0.006) and low hemoglobin concentration (OR=2.84; 95% CI: 1.22-6.59, p=0.021) as independent risk factors for overall postoperative complications. Compliance with nutritional supplements (OR=0.37; 95% CI: 0.14-0.97, p=0.041) and supplementation of malnourished patients as assessed by nutritional specialists (OR=0.24; 95% CI: 0.08-0.69, p=0.009) were independently associated with decreased infectious complications. CONCLUSIONS: Nutritional support based upon NRS-2002 screening might result in overnutrition, with potentially deleterious clinical consequences. We emphasize the importance of detailed assessment of the nutritional status by a dedicated specialist before deciding on early nutritional intervention for patients with an initial NRS-2002 score of ≥3.
