Baculovirus-mediated expression of a Helicobacter pylori protein-based multiepitope hybrid gene induces a potent B cell response in mice.

Helicobacter pylori is a gram-negative bacterium that is present in over half of the world's population. The colonization of the stomach́s gastric mucosa by H. pylori is related to the onset of chronic gastritis, peptic ulcer, and cancer. The estimated deaths from gastric cancer caused by this bacterial infection are in the 15,000-150,000 range. Current treatment for controlling the colonization of H. pylori includes the administration of two to four antibiotics and a gastric ATPase proton pump inhibitor. Nevertheless, the bacterium has shown increased resistance to antibiotics. Despite an extensive list of attempts to develop a vaccine, no approved vaccine against H. pylori is available. Recombinant viruses are a novel alternative for the control of primary pathogenic agents. In this work, we employed a baculovirus that carries a Thp1 transgene coding for nine H. pylori epitopes, some from the literature, and others were selected in silico from the sequence of H. pylori proteins (carbonic anhydrase, urease B subunit, gamma-glutamyl transpeptidase, Lpp20, Cag7, and CagL). We verified the expression of this hybrid multiepitopic protein in HeLa cells. Mice were inoculated with the recombinant baculovirus Bac-Thp1 using various administration routes: intranasal, intragastric, intramuscular, and a combination of intranasal and intragastric. We identified a strong adjuvant-independent IgG-antibody response in the serum of recombinant baculovirus-Thp1 inoculated mice, which was specific for a strain of H. pylori isolated from a human patient. The bacterium-specific IgG-antibodies were present in sera 125 days after the first vaccine administration. Also, H. pylori-specific IgA-antibodies were found in feces at 82 days after the first inoculation. A baculovirus-based vaccine for H. pylori is promising for controlling this pathogen in humans.

The Frailty Based on the Memorial Sloan Kettering Frailty Index for Prediction of Surgical Outcome in Advance Epithelial Ovarian Cancer-Experience of a Single Center in Mexico.

Retrospective impact evaluation of frailty as measured by the Memorial Sloan Kettering Frailty Index (MSK-FI) on outcomes in older women surgically treated for advanced epithelial ovarian cancer (EOC). Women ≥ 60 years with stage IIIC/IV EOC who underwent primary debulking surgery (PDS) or interval debulking surgery (IDS) were included. Medical records were reviewed for patients' characteristics and outcomes. We retrospectively applied the MSK-FI which included 10 comorbidities and functional assessment that were extracted from medical records. The MSK-FI ranges from 0 to 11; a score of ≥ 3 was considered frail. Associations were assessed using logistic regression and Cox proportional hazards regression. We identified 79 patients treated with PDS (n = 36, 45.5%) or IDS (n = 43, 54.4%) with complete data. The prevalence of frailty based on MSK-FI was 25%. Almost half of the frail patients (47.3%) were admitted to the ICU compared to 16% of non-frail patients (p = 0.006). In univariable analysis, the MSK-FI was associated with postoperative complications [OR 1.57 (95% CI 1.04-2.37), p = 0.03] and ICU admission [OR 2.05 (95% CI 1.30-3.23), p = 0.002], but not with readmission rate [OR 1.29 (95% CI 0.65-2.59), p = 0.5], postoperative mortality [OR 1.02 (95% CI 0.51-2.00), p = 0.9], and hospital stay [ß 0.60 (95% CI - 1.19-2.41)]. In multivariable analysis, the frailty index was independently associated with postoperative complications [OR 1.54 (95% CI 1.02-2.34), p = 0.04] and ICU admissions [OR 1.97 (95% CI 1.23-3.16), p = 0.004]. Frailty, based on the Memorial Sloan Kettering Frailty Index, is associated with adverse postoperative outcomes in older women with advanced ovarian cancer, suggesting that MSK-FI can improve the predictive ability of current surgical assessment tools.

Lack of Exposure to Mycobacterium bovis and Mycobacterium avium subsp. paratuberculosis in Chilean Cervids, and Evidence of a New Mycobacterium-Like Sequence.

Screening of serum and fecal samples from huemul (Hippocamelus bisulcus) and pudu (Pudu puda) from southern Chile for Mycobacterium bovis and Mycobacterium avium paratuberculosis (MAP) found all but four samples Mycobacterium-negative. The positive sequences showed only 92-93% similarity with MAP and were from remote Isla Riesco populations.

[Physical exercise and loss of weight and body mass index in bariatric surgery: a systematic review]. / Ejercicio físico y disminución del peso y el índice de masa corporal en la cirugía bariátrica: una revisión sistemática.

INTRODUCTION: Introduction: bariatric surgery is considered successful when the percentage of weight loss is equal to or higher than 25 %, or when the percentage loss of body mass index occurs above 50 % long-term. Objective: to analyze the effect of physical exercise on body weight and body mass index before and/or after bariatric surgery. Methodology: articles registered in the PudMed, Scopus and Web of Science databases were searched for original papers with open access in English and Spanish that compared one or more physical exercise programs as treatment before and/or after bariatric surgery, with results on initial and final weight and body mass index, muscle mass, and fat mass from January to April 2021. Results: a total of 730 articles were obtained in the different databases and only 7 were selected for the analysis. Aerobic exercise combined with resistance training showed a greater decrease in the percentage of weight loss (% PP) and the percentage of loss of body mass index (% PBMI). Conclusions: aerobic physical exercise in combination with endurance training is the most applied program in subjects with bariatric surgery, and the most important effects are an increase in percentage of weight loss and a decrease in body mass index.

Objetivo: analizar el efecto del ejercicio físico en el peso corporal y el índice de masa corporal antes y después de la cirugía bariátrica. Metodología: se buscaron artículos registrados en las bases de datos de PudMed, Scopus y Web of Science, de artículos originales con acceso abierto en inglés y español que compararan uno o varios programas de ejercicio físico como tratamiento antes y/o después de la cirugía bariátrica, con resultados de peso e índice de masa corporal inicial y final, masa muscular y masa grasa, de enero a abril de 2021. Resultados: se obtuvieron en total 730 artículos de las diferentes bases de datos y solo 7 se seleccionaron para el análisis. El ejercicio aerobio combinado con el entrenamiento de resistencia mostró una mayor disminución del porcentaje de peso perdido (% PP) y del porcentaje perdido de índice de masa corporal (% PIMC). Conclusiones: el ejercicio físico aerobio, en combinación con el entrenamiento de resistencia, es el programa más aplicado a los sujetos con cirugia bariátrica y los efectos más importantes son el aumento del porcentaje de pérdida de peso y la disminución del índice de masa corporal.

Pressões respiratórias máximas em indivíduos obesos antes e após cirurgia bariátrica / Maximum respiratory pressure in obese individuals before and after bariatric surgery

A obesidade é uma doença crônica e multifatorial que leva a alterações sistêmicas e é considerada um problema de saúde pública mundial. Entre as alterações respiratórias decorrentes da obesidade se discute como o ganho de peso ou a perda deste pode interferir nas pressões respiratórias máximas (PRM), não existindo consenso na literatura. Objetivo: Analisar o poder preditivo das equações de referência para PMR em obesos antes e após perda de peso. Métodos: Estudo transversal no qual foram incluídos vinte pacientes obesos dos Programas de Cirurgia Bariátrica de hospitais de referência em Manaus/Amazonas, que tiveram as PRM avaliadas por meio de manuvacuometria antes e aproximadamente um ano e meio após a cirurgia bariátrica. Resultados: O peso médio diminuiu de 138,5 ± 21,7 kg para 82,7 ± 8,2 kg após a cirurgia. As PRM foram supranormais antes da cirurgia e reduzidas após a cirurgia. Entre as equações analisadas, apenas as propostas por Sanchez et al. foram capazes de predizer os valores medidos. Conclusão: As PRM foram aumentadas nos obesos mórbidos avaliados e reduzidas após a cirurgia. As equações mais utilizadas na prática clínica brasileira parecem não ser capazes de predizer valores de PRM nessa população, sendo as mais adequadas as propostas por Sanchez et al. (AU)

Obesity is a chronic and multifactorial disease and is considered a global public health problem. Among the respiratory changes due to obesity, weight gain or loss of body weight can interfere with maximal respiratory pressures, and there is no consensus in the literature. Objective: To analyze the predictive power of the reference equations for maximal respiratory pressures in obese before and after weight loss. Methods: A crosssectional study was carried out in which 20 obese patients were included in the Bariatric Surgery Programs of reference hospitals in Manaus/Amazonas. The maximal respiratory pressures were assessed by manuvacuometry before and approximately one year after bariatric surgery. Results: The mean weight decreased from 138.5 ± 21.7 kg to 82.7 ± 8.2 kg after surgery. The maximal respiratory pressures were supranormal before surgery and reduced after surgery. Among the analyzed equations, only those proposed by Sanchez et al. were able to predict the measured values. Conclusion: The maximal respiratory pressures were increased in the morbidly obese evaluated and reduced after the surgery. The most used equations in Brazilian clinical practice seem not to be able to predict maximal respiratory pressures values in this population, being the most adequate those proposed by Sanchez et al. (AU)

Transversus abdominis plane block in cat cadavers: anatomical description and comparison of injectate spread using two- and three-point approaches.

OBJECTIVE: To describe the sonoanatomy of the abdominal wall in live cats and to compare the distribution pattern of two versus three ultrasound-guided transversus abdominis plane (TAP) injections using clinically applicable volumes of lidocaine-dye solution in cat cadavers. STUDY DESIGN: Prospective anatomical study. ANIMALS: A total of eight client-owned healthy cats and eight cat cadavers. METHODS: Ultrasound anatomy of the abdominal wall, landmarks and sites for needle access were determined in live cats. Ultrasound-guided TAP injections were performed in eight thawed cat cadavers. Volumes of 0.25 or 0.16 mL kg-1 per point of a lidocaine-dye solution were injected using either two [subcostal and preiliac (SP)] or three [subcostal, retrocostal and preiliac (SRP)] injection points, respectively. Each cadaver was then dissected to determine the injectate distribution and the number of thoracolumbar nerves stained with each approach. The target nerves were defined as the ventromedial branches of the thoracic nerves 10 (T10), T11, T12, T13 and lumbar nerves 1 (L1) and L2. RESULTS: Sonoanatomy was consistent with anatomy upon dissection and the TAP was identified in all cadavers. A total of 16 subcostal, 16 preiliac and nine retrocostal TAP injections were performed. The overall staining success rate of the target nerves was 66.7% and 92.6% for the SP and SPR approaches, respectively (p = 0.02). The ventromedial branches of T10, T11, T12, T13, L1 and L2 were stained in 57.1%, 100.0%, 85.7%, 28.6%, 42.9% and 85.7%, and in 66.7%, 100.0%, 100.0%, 100.0%, 88.9% and 100.0% of the cases with the SP and SRP approaches, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: The SRP approach allowed a broader distribution around the target nerves, whereas a staining gap was observed at T13 and L1 with the SP approach. Further studies are necessary to investigate the analgesic effect of these approaches in a clinical setting.

Agreement between noninvasive oscillometric and invasive blood pressure measurements in isoflurane-anesthetized guinea pigs (Cavia porcellus).

OBJECTIVE: To assess the agreement between an oscillometric device and invasive blood pressure (IBP) measurements in anesthetized healthy adult guinea pigs. STUDY DESIGN: Prospective experimental study. ANIMALS: A total of eight adult Hartley guinea pigs. METHODS: All animals were anesthetized; a carotid artery was surgically exposed and catheterized for IBP measurements. A size 1 cuff placed on the right thoracic limb was connected to an oscillometric device for noninvasive blood pressure (NIBP) assessment. Concurrent pairs of systolic (SAP), diastolic (DAP) and mean (MAP) arterial pressures were recorded simultaneously with both methods every 3 minutes for 30 minutes. Agreement between IBP and NIBP measurements was determined using the Bland-Altman method, considering the recommended standards for the validation of NIBP measurement devices proposed by the American College of Veterinary Internal Medicine (ACVIM). RESULTS: The bias and the 95% limits of agreement were: -14 (-31 to 3) mmHg, -2 (-14 to 10) mmHg and -1 (-13 to 11) mmHg for SAP, DAP and MAP, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: The oscillometric device used in this study to measure NIBP did not meet ACVIM criteria for validation. It showed good agreement for DAP and MAP but not for SAP measurements. Considering the small size of these animals and the resulting difficulty in performing percutaneous arterial catheterization, this device might be a useful tool to assess MAP and DAP during anesthetic procedures in adult guinea pigs.

Cateterismo de senos petrosos en el diagnóstico etiológico de síndrome de Cushing: primera experiencia en Uruguay / Petrosal sinus sampling for etiological diagnosis of Cushing's syndrome: first experience in Uruguay / Cateterismo dos seios petrosos no diagnóstico etiológico da síndrome de Cushing: primeira experiência no Uruguai

Resumen: Identificar la causa de un síndrome de Cushing dependiente de adrenocorticotropina (ACTH) es esencial para realizar un tratamiento correcto. La hipersecreción de ACTH es debida en su mayoría a un tumor hipofisario (enfermedad de Cushing) o, en un 10%-20%, a tumores con producción ectópica de esta hormona. Los test no invasivos tienen baja sensibilidad y especificidad para diferenciar estas dos etiologías. El patrón oro lo constituye el cateterismo bilateral de los senos petrosos inferiores (CSP). Mediante el CSP se demuestra la hipersecreción de ACTH a nivel hipofisario al documentar un gradiente de ACTH central a periférico en el drenaje del tumor. Se recomienda realizarlo en todo síndrome de Cushing ACTH dependiente, aunque suele reservarse para pacientes con diagnóstico de hipercortisolismo y hallazgos negativos o equívocos en la resonancia nuclear magnética (RNM) de la región selar. Presentamos el primer caso en Uruguay en que se utilizó el CSP como método diagnóstico, una mujer de 55 años que presentó un hipercortisolismo ACTH-dependiente con una imagen adenohipofisaria <6 mm. El gradiente petroso-periférico confirmó el diagnóstico de enfermedad de Cushing y no hubo complicaciones durante el procedimiento. Posteriormente se realizó la resección del adenoma mediante cirugía transesfenoidal, con buena evolución y confirmación inmunohistoquímica del tumor.

Summary: Identifying the cause of adrenocorticotropin (ACTH)-dependent Cushing's syndrome is key to define the appropriate treatment. Hypersecretion of the adrenocorticotropic hormone (ACTH) is mainly caused by a pituitary tumor (Cushing's syndrome) or, in 10% to 20% of cases, by tumors with ectopic production of this hormone. Differentiation between these two etiologies may not be easy due to the low sensitivity and specificity of non- invasive tests. Bilateral sampling of the lower petrosal sinus is the gold standard to differentiate between a pituitary and an ectopic origin, showing the pituitary ACHT hypersecretion and recording the central-to-peripheral ACTH gradient in the tumor's drainage. Despite it being highly recommended for all cases of ACTH-dependent Cushing's syndrome, it is reserved for patients with a diagnosis of hypercortisolism and negative or misleading findings in the MRI of the sellar region. The study presents the first case of petrosal sinus sampling for diagnostic purposes in Uruguay, in a 55-year-old woman with ACHT-dependent hypercortisolism showing an adenohypophysis image < 6 mm. The petrosal-peripheral gradient confirmed the diagnosis of Cushing's syndrome and no complications arose during the procedure. Afterwards a transsphenoidal surgery was performed for resection of the adenoma. Evolution was good and immunochemistry confirmed the tumor's etiology.

A seguir, o adenoma foi ressecado por cirurgia transesfenoidal, com boa evolução e confirmação imunohistoquímica do tumor.

Development of a lateral ultrasound-guided approach for the proximal radial, ulnar, median and musculocutaneous (RUMM) nerve block in cats.

OBJECTIVE: To describe a lateral ultrasound (US)-guided approach to the radial, ulnar, median and musculocutaneous (RUMM) nerves through a single proximal in-plane insertion in cats and to determine whether one or two injection points are required to successfully stain all the target nerves. STUDY DESIGN: Prospective study. ANIMALS: A total of eight client-owned healthy cats and 12 cat cadavers. METHODS: In live cats, the US anatomy of the brachium, the landmarks and the site for needle accesses were determined. Then, 12 thawed feline cadavers were used to assess the spread of dye solution and nerve staining following the US-guided proximal-lateral-humeral RUMM injection using one and two injection points. Each cadaver was injected with 0.15 mL kg-1 of a 0.25% new methylene blue solution in either a single injection aimed for the radial nerve of one limb (G1) or via two sites delivering 0.1 mL kg-1 and 0.05 mL kg-1 aimed for the radial and musculocutaneous nerves of the opposite limb, respectively (G2). Upon dissection, staining of the target nerves around their circumference for length of >1 cm was considered successful. RESULTS: Sonoanatomy was consistent with anatomy upon dissection and target nerves were identified in all cadavers. Staining was 100% successful for the radial, median and ulnar nerves in both groups, and 41.7% and 100% for the musculocutaneous nerve in G1 and G2, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: This novel lateral US-guided approach for the proximal RUMM nerve block allowed a good identification of the nerves and related structures, and it provided a consistent muscular structure through which the needle could be easily guided. An injection performed in two aliquots (within the caudal and cranial compartments of the neurovascular sheath) appeared to be necessary to successfully stain all the target nerves.

Predictive equations for respiratory muscle strength by anthropometric variables.

Recent studies have pointed out divergences in the predictive quality of reference equations for respiratory muscle strength, alerting the need to introduce into these equation-specific variables for certain target populations. OBJECTIVES: This study proposes predictive equations of respiratory muscle strength by the variables such as body weight and body mass index (BMI = weight/height2 ). MATERIALS AND METHODS: This is a cross-sectional study, and the evaluation was made by the test of maximum static respiratory pressures (MIP and MEP) according to standard protocol of the Brazilian Society of Pneumology and Tisiology. For data analysis, the following three models of linear regression were adjusted: age, age/weight, age/BMI. The software used in the analysis was the R version 3.2.1. RESULTS: Of the 353 subjects evaluated (229 women and 124 men), 109 subjects were normal weight, 101 subjects were overweight and 143 subjects were obese. The BMI average of the individuals was 31.42 ± 10.26 kg/m2 and age 46.26 ± 16.47 years. The two statistical models that considered the variables weight and BMI had the R2 value of 29.86% for MEP and 21.77% for MIP when the weight was the predictive variable and 21.33% for MIP and 28.38% for MEP when the variable was BMI. CONCLUSION: It was found with the adjusted models that there was a considerable gain in the predictive quality of the models for MEP and MIP adding weight or BMI, without significant difference between both.

Ultrasound-assisted reaction of 1,4-naphthoquinone with anilines through an EDA complex.

Naphthoquinone amino derivatives exhibit interesting physicochemical properties and a wide range of biological activities with potential medicinal applications. A clean, fast and simple method for the preparation of phenylamino-1,4-naphthoquinones is presented by the reaction of naphthoquinone (NQ) and anilines under ultrasound irradiation (US). Anilino derivatives were synthesized in good yields and shorter reaction times in comparison with the conventional method. This ultrasound procedure can be applied to the preparation of naphthoquinone derivatives with anilines containing electron-donor substituents (2-OMe, 4-OMe, 4-Me and 4-OEt) or halogen or electron-withdrawing substituents (4-F, 4-Cl, 4-Br, 3-F, 3-Cl, 3-Br, 4-Ac). This procedure was also applied to the reaction of anilines with 2,3-dichloro-1,4-naphthoquinone (DCNQ). A reaction mechanism involving an EDA complex is proposed based on NMR experiments and previous studies about solid/solid reactions.

Polimorfismo do gene de receptor da leptina e a obesidade / Leptin receptor gene polymorphism and the obesity

Introdução: A obesidade consiste em um complexo conjunto de fatores comportamentais, ambientais e genéticos que se relacionam e se potencializam. Acredita-se que polimorfismos de nucleotídeo único (SNPs) possuam relação com a obesidade e que estejam hiperexpressos nesta condição. Objetivo: Revisar a relação da presença de polimorfismos no gene LEPR com a obesidade em crianças e adolescentes, buscando evidenciar condições e/ou fatores ambientais relacionados. Métodos: Trata-se de um artigo de atualização sobre o tema polimorfismo do LEPR e a associação com a obesidade. Resultados: Os dados levantados mostram a influência de polimorfismos do gene receptor de leptina (LEPR) com o desenvolvimento da obesidade, assim como fatores ambientais, tais como dieta hipercalórica na presença do polimorfismo, potencializam o desenvolvimento dessa condição clínica, resultando em aumento das medidas antropométricas e bioquímicas, na presença da mutação genética.

Methods: This is an update article on the topic LEPR polymorphism and the association with obesity. Results: The data collected show the influence of polymorphisms of the Leptin receptor gene (LEPR) with the development of obesity as well as environmental factors such as caloric diet in the presence of the polymorphism potentiate the development of this medical condition, resulting in increase of action anthropometric and biochemical in the presence of gene mutation.

Determinação do risco cardiovascular em adultos jovens universitários / Determination of cardiovascular risk in young adults university students

O objetivo deste estudo foi determinar o risco cardiovascular em uma população de adultos jovens universitários que frequentam os cursos de Educação Física e Fisioterapia na Universidade Federal do Amazonas utilizando o Escore de Framingham e o Escore de Risco Global. Trata-se de um estudo observacional transversal onde foram avaliados 63 indivíduos de ambos os sexos com 20-30 anos. Os métodos de avaliação incluíram questionário, análise antropométrica e coleta sanguínea para realização dos exames bioquímicos. Para determinação do risco cardiovascular foram utilizados os escores de Framingham (ERF) e Risco Global (ERG) para uma idade modificada de 65 anos. As análises estatísticas foram descritivas (média, desvio-padrão, frequência simples e percentagem). O Teste t de Student foi aplicado para comparação entre grupos (p<0,05). O ERF identificou, entre o sexo masculino 23,53% com baixo risco e 76,47% com risco intermediário para desenvolvimento de doença cardiovascular nos próximos 10 anos. Todas as mulheres apresentaram baixo risco. O ERG demonstrou que entre os homens, 94,12% apresentaram risco intermediário e 5,88% alto risco, e dentre as mulheres 63,04% estavam na faixa de baixo risco e 36,96% risco intermediário. Os resultados demonstram a ocorrência de níveis intermediários no desenvolvimento de DCV na população de adultos jovens nos próximos 10 anos figurando-os como alvo imediato de ações preventivas.

The objective of this study was to determine the cardiovascular risk in a population of young university students attending the courses of Physical Education and Physiotherapy at the Federal University of Amazonas using the Framingham Score and the Global Risk Score. It is a cross-sectional observational study in which 63 individuals of both sexes with 20-30 years were evaluated. Methods of evaluation included questionnaire, anthropometric analysis and blood collection for biochemical tests. The Framingham (FRE) and Global Risk (GRE) scores for a modified age of 65 years were used to determine cardiovascular risk. Statistical analyzes were descriptive (mean, standard deviation, simple frequency and percentage). Student's t-test was applied for comparison between groups (p <0.05). The FRE identified 23.53% of men with low risk and 76.47% with intermediate risk for cardiovascular disease in the next 10 years. All women were at low risk. The GRE showed that among the men, 94.12% presented intermediate risk and 5.88% high risk, and among the women 63.04% were in the low risk range and 36.96% intermediate risk. The results demonstrate the occurrence of intermediate levels in the development of CVD in the population of young adults in the next 10 years, as an immediate target for preventive actions.

Artritis neumocócica en población pediátrica / Pneumococcal arthritis in paediatric population

Introducción. Se revisan los casos de artritis séptica en población pediátrica por Streptococcus pneumoniae en el Área Sanitaria de Santiago de Compostela. Material y métodos. Se realizó una revisión retrospectiva de los aislamientos de S. pneumoniae en líquidos articulares en niños el período de enero de 2005 a marzo de 2014. Resultados. De los 7.416 líquidos articulares recibidos en el Servicio de Microbiología, 77 pertenecían a pacientes pediátricos, y de ellos, solamente 8 tuvieron cultivo positivo. En total fueron tres casos positivos para S. pneumoniae, dos con cultivo positivo y un tercero con detección antigénica positiva en el líquido articular. En los tres pacientes (dos de ellos menores de 15 meses) la articulación afectada fue la cadera, se combinó el tratamiento antibiótico con el drenaje quirúrgico y la evolución fue favorable. Conclusiones. La artritis neumocócica es una entidad que debe ser tenida en cuenta ya que la mayoría de los cuadros de artritis en población pediátrica aparecen como complicación de una bacteriemia posterior a un cuadro catarral o una otitis. El mayor riesgo de secuelas se asocia a retrasos en el diagnóstico, por ello es imprescindible un diagnóstico precoz clínico y microbiológico (AU)

Introduction. Cases of septic arthritis in paediatric population by Streptococcus pneumoniae in the Health Area of Santiago de Compostela (Spain) were reviewed. Material and methods. A retrospective study from January 2005 to March 2014 was conducted for all S. pneumoniae isolates obtained from joint fluids in children. Results. From the 7,416 joint fluids received in the Microbiology Department, 77 belonged to paediatric patients, and of these, only 8 had positive culture. In total, there were three positive cases for S. pneumoniae, two with positive culture and a third with positive antigen detection. In the three patients (two of them under 15 months) the affected joint was hip, antibiotic treatment was combined with surgical drainage and evolution was favourable. Conclusions. We conclude that pneumococcal arthritis is an entity that must be taken into account since most cases of arthritis in paediatric population appear as a complication of bacteraemia after a common cold or an ear infection. The greatest risk of sequel is associated with delays in diagnosis, so it is essential clinical and microbiological early diagnosis (AU)

Aspiração endotraqueal de adultos intubados: evidências para boas práticas / Endotracheal suctioning of the adults intubated: evidence for best practice

Introdução: A aspiração endotraqueal é o procedimento invasivo mais realizado em indivíduos intubados em unidades de terapia intensiva. Contudo, existem poucos estudos nacionais de boa qualidade metodológica sobre o assunto, não havendo no Brasil consenso da literatura e/ou padronização da técnica. Objetivos: Estabelecer recomendações baseadas em evidências científicas sobre a aspiração endotraqueal em adultos intubados. Métodos: Revisão sistemática de estudos secundários: diretrizes, guidelines e revisões sistemáticas em inglês e português, pesquisada nas bases de dados PubMed, Cochrane, Cochrane Review, Cochrane Library, Scielo Org, Scielo Brasil, PEDro, Clinical Evidence e Evidence Based Medicine. Resultados: Foram incluídos cinco artigos com classificação entre C e D pelo R-Amstar. Conclusão: A aspiração endotraqueal deve ser realizada em adultos intubados por pessoal qualificado, assepticamente, sempre que necessária. Não deve exceder 15 segundos por aspiração e nem ser realizada rotineiramente, e sim, na presença de secreções ­ grau de recomendação A. A sonda de aspiração deve ter um diâmetro menor que 50% do tubo endotraqueal e a hiperoxigenação com fração inspirada de oxigênio a 100% no ventilador deve ser utilizada ­ grau de recomendação A. A pressão de sucção não deve exceder 150 mmHg negativos ­ grau de recomendação B. É recomendada a aspiração subglótica, especialmente naqueles indivíduos com mais de 72 horas de ventilação mecânica invasiva ­ grau de recomendação A. (AU)

Introduction: Endotracheal aspiration is the most accomplished invasive procedure in intubated individuals in intensive care units. However, there are few national studies of good methodological quality on the subject, and there is no consensus in the literature and / or standardization of the technique. Aims: To establish recommendations based on scientific evidence on endotracheal aspiration in intubated adults. Methods: Systematic review of secondary studies: guidelines, guidelines and systematic reviews in English and Portuguese, searched in the databases PubMed, Cochrane, Cochrane Review, Cochrane Library, Scielo Org, Scielo Brazil, PEDro, Clinical Evidence and Evidence Based Medicine. Results: Five articles with classification between C and D by R-Amstar were included. Conclusion: Endotracheal aspiration should be performed in adults intubated by qualified personnel, aseptically, whenever necessary. It should not exceed 15 seconds per aspiration and should not be performed routinely, but in the presence of secretions - degree of recommendation A. The aspiration probe should have a diameter of less than 50% of the endotracheal tube and hyperoxigenation with inspired fraction of oxygen at 100% in the ventilator should be used - degree of recommendation A. The suction pressure should not exceed 150 mmHg negative - degree of recommendation B. Subglottic aspiration is recommended, especially in those individuals with more than 72 hours of invasive mechanical ventilation - degree of Recommendation A. (AU)

Consumo alimentar de crianças do ensino fundamental em uma instituição pública / Consumo alimentario de niños de la educación primaria en una institución pública / Food consumption of children of fundamental education in a public institution

Objetivo verificar o consumo alimentar e a classe econômica de escolares de ensino fundamental em uma instituição pública. Método estudo transversal quantitativo e qualitativo com 43 escolares entre 6 e 11 anos, de ambos os sexos, da rede municipal de Manaus, Amazonas, Brasil. Os dados foram obtidos mediante questionário semiestruturado com informações de consumo alimentar e socioeconômicas e pela observação participante. Resultados foi verificado alto consumo de produtos industrializados, fontes de proteína de origem animal, gorduras e açúcares refinados, e baixo consumo de fibras e pescados, bem como pouca aderência aos alimentos oferecidos pela escola, independente de classe econômica. Conclusão o reduzido consumo de vegetais e frutas em todas as classes socioeconômicas e o frequente consumo de biscoitos, doces e produtos de processamento industrial refletem a baixa qualidade da dieta das crianças.

Reabilitação pulmonar em indivíduos com fibrose pulmonar idiopática: qual a evidência? / Pulmonary rehabilitation in individuals with idiopathic pulmonary fibrosis: what is the evidence?

Introdução: A fibrose pulmonar idiopática (FPI) é uma pneumonia intersticial idiopática crônica, progressiva, sem cura, com morte entre 3 meses a 4 anos após o diagnóstico. A qualidade de vida (QV) dos indivíduos com FPI é baixa, com muitos sintomas respiratórios. Têm-se demonstrado que a melhora da QV e dos sintomas pode ocorrer com a reabilitação pulmonar (RP). Contudo, existem poucos estudos nacionais sobre o assunto sendo esta conduta pouca realizada no Brasil. Objetivos: Investigar evidências científicas sobre a RP em indivíduos com FPI. Métodos: Revisão sistemática de estudos secundários: diretrizes, guidelines e revisões sistemáticas, em inglês e português, publicados entre 2000 e 2016 nas bases de dados: BVS, Cochrane Library, PEDro, PubMed, Scielo Org. Os descritores e seus correlatos foram identificados no Medical Subject Headings e nos Descritores em Ciências da Saúde. A questão PICO foi: P: indivíduo com FPI, I: reabilitação pulmonar, O: tempo livre de piora, dispneia, distância percorrida no teste de caminhada de 6 minutos, saturação periférica de oxigênio (SpO2), QV, capacidade vital forçada (CVF) e sobrevida. A qualidade metodológica foi avaliada através do Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) e do Revised Assessment of Multiple Systematic Reviews (R-AMSTAR). O grau de recomendação e a sugestão da prática foram baseados no United States Preventive Services Task Force (USPSTF). Resultados: Seis artigos foram incluídos com boa qualidade metodológica. A RP foi recomendada para a maioria dos indivíduos com FPI ­ grau de recomendação B. Conclusão: A RP foi capaz de melhorar positivamente a maioria dos desfechos analisados, devendo ser incluída no rol de condutas terapêuticas para indivíduos com FPI que desejarem realiza-la. (AU)

Introduction: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive and idiopathic interstitial pneumonia, uncured, with fatal issue in 3 months to 4 years after diagnosis. Quality of life (QOL) of patients with IPF is weak, with many respiratory symptoms. Improving QOL and symptoms can occur with pulmonary rehabilitation (PR). However, there are few national studies on the subject and this rehabilitation has little place in Brazil. Objectives: To investigate scientific evidence available on the RP in patients with IPF. Methods: Systematic review of secondary studies: policies, guidelines and systematic reviews in English and Portuguese, published between 2000 and 2016 in the data bases: BVS, Cochrane Library, PEDro, PubMed, Scielo Org. Descriptors and their specific correlates were identified in the Medical Subject Headings (MESH) and the Descriptors in Health Sciences (DECS). The question PICO was: P: individual with IPF, I: pulmonary rehabilitation, O: outcome: worsening of free time, dyspnea, distance walked in 6-minute walk test, oxygen saturation (SpO2), QOL, forced vital capacity (FVC) and survival. Methodological quality was assessed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the Revised Assessment of Multiple Systematic Reviews (R-AMSTAR). The degree of recommendation and practical suggestions were based on the United States Preventive Services Task Force (USPSTF). Results: Six articles were included with good methodological quality. The RP is recommended for most individuals with IPF - degree of recommendation B. Conclusion: The RP was able to positively improve most of the outcomes and should be included in the list of therapeutic approaches for individuals with IPF who want to achieve it.(AU)
