Fat infiltration in the lumbar multifidus and erector spinae muscles in subjects with sway-back posture

Decreased activity of the lumbar stabilizer muscles has been identified in individuals with sway-back posture. Disuse can predispose these muscles to atrophy, which is characterized by a reduced cross-sectional area (CSA) and by fat infiltration. The aim of this study was to evaluate the amount of fat infiltration in the lumbar multifidus and lumbar erector spinae muscles as a sign of the muscle atrophy in individuals with sway-back posture, with and without low back pain. Forty-five sedentary individuals between 16 and 40 years old participated in this study. The sample was divided into three groups: symptomatic sway-back (SSBG) (n = 15), asymptomatic sway-back (ASBG) (n = 15), and control (CG) (n = 15). The individuals were first subjected to photographic analysis to classify their postures and were then referred for a magnetic resonance imaging (MRI) examination of the lumbar spine. The total (TCSA) and functional (FCSA) cross-sectional areas of the lumbar erector spinae together with lumbar multifidus and isolated lumbar multifidus muscles were measured from L1 to S1. The amount of fat infiltration was estimated as the difference between the TCSA and the FCSA. Greater fat deposition was observed in the lumbar erector spinae and lumbar multifidus muscles of the individuals in the sway-back posture groups than in the control group. Pain may have contributed to the difference in the amount of fat observed in the groups with the same postural deviation. Similarly, sway-back posture may have contributed to the tissue substitution relative to the control group independently of low back pain. The results of this study indicate that individuals with sway-back posture may be susceptible to morphological changes in their lumbar erector spinae and lumbar multifidus muscles, both due to the presence of pain and as a consequence of their habitual posture.

The panicolytic-like effect of fluoxetine in the elevated T-maze is mediated by serotonin-induced activation of endogenous opioids in the dorsal periaqueductal grey

Serotonin (5-HT), opioids and the dorsal periaqueductal grey (DPAG) have been implicated in the pathophysiology of panic disorder. In order to study 5-HT-opioid interaction, the opioid antagonist naloxone was injected either systemically (1 mg/kg, i.p.) or intra-DPAG (0.2 mu g/0.5 mu L) to assess its interference with the effect of chronic fluoxetine (10 mg/kg, i.p., daily for 21 days) or of intra-DPAG 5-HT (8 mu g/0.5 mu L). Drug effects were measured in the one-escape task of the rat elevated T-maze, an animal model of panic. Pretreatment with systemic naloxone antagonized the lengthening of escape latency caused by chronic fluoxetine, considered a panicolytic-like effect that parallels the drug's therapeutic response in the clinics. Pretreatment with naloxone injected intra-DPAG antagonized both the panicolytic effect of chronic fluoxetine as well as that of 5-HT injected intra-DPAG. Neither the performance of the inhibitory avoidance task in the elevated T-maze, a model of generalized anxiety nor locomotion measured in a circular arena was affected by the above drug treatments. These results indicate that the panicolytic effect of fluoxetine is mediated by endogenous opioids that are activated by 5-HT in the DPAG. They also allow reconciliation between the serotonergic and opioidergic hypotheses of panic disorder pathophysiology.

The Role of Dyslipidemia on Ocular Surface, Lacrimal and Meibomian Gland Structure and Function

Purpose: Dyslipidemia is characterized by high lipid blood levels that are risk factors for cardiovascular diseases, which are leading causes of death. However, it is unclear whether dyslipidemia is a cause of the dry eye syndrome (DES). Therefore we determined in transgenic mice models of dyslipidemia, whether there is an association with DES development. Methods: Dyslipidemic models included male and female adult mice overexpressing apolipoprotein CIII (Apo CIII), LDL receptor knockout (LDLR-KO) and ApoE knockout (ApoE-KO). They were compared with age-and gender-matched C57BL/6 mice. Ocular health was evaluated based on corneal slit lamp assessment, phenol red thread test (PRT) and impression cytology. Blood lipid profiles and histology of meibomian and lacrimal glands were also evaluated. Effects of high-fat diet and aging were observed in LDLR-KO and ApoCIII strains, respectively. Results: Body weight and lacrimal gland weight were significantly higher in male mice compared to females of the same strain (P < 0.05). Body weight was significantly lower in LDLRKO mice receiving high lipid diet compared to their controls (P = 0.0043). ApoE-KO were hypercholesterolemic and ApoCIII hypertriglyceridemic while LDLR-KO showed increases in both parameters. The PRT test was lower in male LDLR-KO mice with high-fat diet than control mice with standard diet (P = 0.0273). Aging did not affect lacrimal structural or functional parameters of ApoCIII strain. Conclusions: DES development is not solely dependent on dyslipidemia in relevant mice models promoting this condition. On the other hand, lacrimal gland structure and function are differentially impacted by lipid profile changes in male and female mice. This dissociation suggests that other factors beside dyslipidemia impact on tear film dysfunction and DES development.

Oral health as a predictive factor for oral mucositis

OBJECTIVES: Oral mucositis is a complication frequently associated with hematopoietic stem cell transplantation, decreasing a patient’s quality of life and increasing the occurrence of opportunistic infections. The purpose of this study was to determine the incidence and severity of oral mucositis and to assess the correlation of this disease with the oral health of an individual at the time of hematopoietic stem cell transplantation. METHODS: Before transplantation, patients’ oral health and inflammatory conditions were determined using the gingival index and the plaque index, which are based on gingival bleeding and the presence of dental plaque, respectively. Additionally, the dental health status was determined using the decayed, missing, and filled teeth index. The monitoring of oral mucositis was based on the World Health Organization grading system and was performed for five periods: from Day 0 to D+5, from D+6 to D+10, from D+11 to D+15, from D+16 to D+20, and from D+21 to D+30. RESULTS: A total of 97 patients (56% male and 44% female) who underwent hematopoietic stem cell transplantation at the Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo between January 2008 and July 2009 were prospectively examined. The incidence of ulcerative mucositis was highest from days +6 to +10 and from days +11 to +15 in the patients who underwent autologous and allogeneic hematopoietic stem cell transplantation, respectively. CONCLUSION: The data, including the dental plaque and periodontal status data, showed that these oral health factors were predictive of the incidence and severity of oral mucositis in a cohort of patients with similar conditioning regimens before hematopoietic stem cell transplantation

Prospective surveillance study of acute respiratory infections, influenza-like illness and seasonal influenza vaccine in a cohort of juvenile idiopathic arthritis patients

Background Acute respiratory infections (ARI) are frequent in children and complications can occur in patients with chronic diseases. We evaluated the frequency and impact of ARI and influenza-like illness (ILI) episodes on disease activity, and the immunogenicity and safety of influenza vaccine in a cohort of juvenile idiopathic arthritis (JIA) patients. Methods Surveillance of respiratory viruses was conducted in JIA patients during ARI season (March to August) in two consecutive years: 2007 (61 patients) and 2008 (63 patients). Patients with ARI or ILI had respiratory samples collected for virus detection by real time PCR. In 2008, 44 patients were immunized with influenza vaccine. JIA activity index (ACRPed30) was assessed during both surveillance periods. Influenza hemagglutination inhibition antibody titers were measured before and 30-40 days after vaccination. Results During the study period 105 ARI episodes were reported and 26.6% of them were ILI. Of 33 samples collected, 60% were positive for at least one virus. Influenza and rhinovirus were the most frequently detected, in 30% of the samples. Of the 50 JIA flares observed, 20% were temporally associated to ARI. Influenza seroprotection rates were higher than 70% (91-100%) for all strains, and seroconversion rates exceeded 40% (74-93%). In general, response to influenza vaccine was not influenced by therapy or disease activity, but patients using anti-TNF alpha drugs presented lower seroconversion to H1N1 strain. No significant differences were found in ACRPed30 after vaccination and no patient reported ILI for 6 months after vaccination. Conclusion ARI episodes are relatively frequent in JIA patients and may have a role triggering JIA flares. Trivalent split influenza vaccine seems to be immunogenic and safe in JIA patients.

Transferência transplacentária de anticorpos em gestações gemelares

Há poucos dados na literatura sobre o transporte transplacentário de imunoglobulinas em gestações múltiplas. O objetivo deste estudo foi observar fatores que influenciam a concentração de imunoglobulina G (IgG) no cordão umbilical dos neonatos e a transferência transplacentária de IgG total e de IgG contra o Streptococcus grupo B (EGB), e lipopolissacarídeos (LPS) de Klebsiella spp. e Pseudomonas spp.. Métodos: estudo prospectivo realizado no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo no período de 2012 a 2013. Foram coletadas amostras de sangue materno e de cordão umbilical no momento do parto. Os critérios de inclusão foram gestações gemelares com ausência de sinais de infecção por HIV, citomegalovírus, Hepatites B e C, toxoplasmose e rubéola e ausência de doenças autoimunes, malformação fetal e síndromes genéticas. A análise multivariada foi realizada para avaliar a associação entre os níveis de IgG em cordão umbilical e as taxas de transferência de anticorpos com a concentração materna de IgG, a corionicidade da gestação, a presença de insuficiência placentária, a restrição de crescimento intrauterino, a idade gestacional de nascimento, o peso de nascimento, o tabagismo, a doença materna e a via de parto. Resultados: a concentração de IgG total em cordão umbilical apresentou correlação positiva com os níveis maternos séricos de IgG total e a idade gestacional do parto. Os níveis de IgG total em cordão umbilical foram significativamente menores em gestações monocoriônicas quando comparadas às dicoriônicas. A taxa de transferência de IgG total apresentou correlação positiva com a idade gestacional do parto, mas negativa com as concentrações maternas de IgG total. As concentrações de IgG contra EGB e LPS de Klebsiella spp. e Pseudomonas spp. apresentaram associação com os níveis maternos de IgG específicos contra esses antígenos e com o diabetes. Os níveis de IgG contra LPS de Klebsiella spp. também foram associados com o peso de nascimento e com hipertensão materna. As taxas de transferência de IgG contra EGB e LPS de Pseudomonas spp. apresentaram correlação com os níveis maternos de IgG específicos contra os antígenos referidos. A taxa de transferência de IgG contra EGB também esteve associada com a idade gestacional do parto, enquanto a taxa de transferência de IgG contra LPS de Pseudomonas spp. apresentou correlação com diabetes. Não houve correlação entre a taxa de transferência de IgG contra a LPS de Klebsiella spp. com nenhum fator analisado. Conclusão: em gestações gemelares, a concentração total de IgG em cordão umbilical foi influenciada pela concentração materna de IgG total, pela idade gestacional do parto e pela corionicidade placentária. As concentrações de IgG total foram significativamente menores em gestações monocoriônicas que em dicoriônicas. As concentrações séricas de IgG contra EGB e LPS de Klebsiella spp. e Pseudomonas spp. em cordão umbilical apresentaram associação com os níveis maternos de IgG específicos contra esses antígenos e com a presença de diabetes. Todos os outros parâmetros estudados apresentaram diferentes associações com as concentrações de IgG e com as taxas de transferências de IgG específicas contra cada antígeno investigado

RESUMO - Contexto: A avaliação das práticas de um hospital na utilização do transporte não urgente, mais concretamente, a análise do procedimento utilizado nas respectivas requisições de transporte não urgente, por patologia, da estrutura de custos por tipo de transporte e sua validação em termos de conformidade para respectivo pagamento. Objectivos: Os objectivos deste trabalho são a i) avaliação da adequação das práticas do transporte não urgente, do Hospital Geral de Santo António (HGSA) do Centro Hospitalar do Porto (CHP), ao normativo legal em vigor, ii) do grau de conformidade das requisições de transporte analisadas com os critérios clínicos estabelecidos, iii) mensurar os custos de transporte programado na estrutura hospitalar e avaliar a dimensão dos transportes injustificados/inadequados, no orçamento do HGSA. Metodologia: A partir da análise do normativo legal do transporte não urgente e do Regulamento Interno do HGSA, foram criadas duas matrizes, feita uma análise comparativa entre as mesmas, com o objectivo de permitir aferir do grau de conformidade do Regulamento face ao normativo legal. De 560 requisições de transporte e de 525 facturas de transporte não urgente, foi realizada uma comparação do grau de adequação das práticas do HGSA face ao estabelecido legal e clinicamente. Na vertente da análise do grau de conformidade do Regulamento face ao normativo legal foram os dois documentos comparados de acordo com os requisitos estabelecidos na Lei, tendo sido definidas as seguintes variáveis para as seguintes situações: i) situações abrangidas pelo transporte não urgente, taxa de conformidade situações abrangidas (TCSA) ii) justificações clinicas para o direito a tal tipo de transporte, taxa de conformidade justificações clinicas (TCJC) tendo, posteriormente, sido definida e calculada uma taxa global de conformidade (TCG). Na vertente do grau de adequação entre os critérios clínicos definidos e a sua aplicação prática bem como da definição da dimensão dos custos e sua representatividade no transporte injustificado/inadequado foram, para a primeira questão, criadas quatro variáveis, Transporte Justificado (TJ), Transporte Justificado mas não o meio utilizado (TJnm), Transporte Justificado mas sem sustentação clínica (TJssc) e Transporte Não Justificado (TNJ) e para a segunda questão três variáveis, o Transporte em Ambulância (TA), o Transporte em Táxi (TT) e o Transporte Publico ou Próprio (TP). Resultados: Conclui-se do presente estudo que o Regulamento Interno do CHP tem, nas duas situações em análise, um grau elevado de conformidade com o respectivo normativo legal, de acordo com a Taxa de Conformidade Global (80%). Também é possível concluir na adequação dos critérios clínicos definidos à sua aplicação prática que os mesmos se adequam em 85,7% das situações analisadas, ou seja, em 85,7% das vezes o transporte estava justificado, sendo que em 38% das vezes o transporte estava integralmente justificado, em 49% das vezes estava justificado mas não o meio utilizado e em 14% encontrava-se justificado mas sem a sustentação clinica devida. No que respeita ao tipo de transporte utilizado dos transportes justificados, 90 % foi realizado em ambulância, 8% em táxi e 2% em transporte publico ou próprio e dos transportes não justificados 92,5% foi realizado em ambulância, 2,5% em táxi e 5% em transporte publico ou próprio. No que concerne à causa clínica, nos transportes justificados, 53,3% deve-se a problemas do aparelho locomotor, 25% a alterações neurológicas, 16,3% a patologias que condicionam incapacidade funcional em repouso ou para a actividade mínima diária, 4,6% a transplante renal, 0,4% a Hemodiálise/Diálise e 0,4% a casos sociais e nos transportes injustificados, 69,2% deveu-se a alterações neurológicas e 30,8% a problemas do aparelho locomotor. O custo do transporte injustificado ascendeu a 304.172,50 € enquanto o do transporte inadequado ascendeu a 187.263 €.

Critérios de adequação em ecocardiografia e a repercussão clinica no outcome do paciente: a realidade do Lister Hospital - East and North Hertfordshire NHS Trust, Reino Unido

RESUMO - Introdução: Os critérios de adequação (Appropriate Use Criteria - AUC) em Ecocardiografia Transtorácica (ETT) foram publicados com o intuito de permitir o uso racional da ecocardiografia, de influenciar decisões clinicas, prestar cuidados de saúde de elevada qualidade e melhorar o outcome dos pacientes. A relação entre a adequação destes e o seu impacto clinico ainda não se encontra largamente estudada. Objectivo: Neste estudo pretendeu-se avaliar o grau de adesão aos AUC em ETT, em diferentes contextos de atendimento e de acordo com diferentes especialidades, bem como o impacto clínico do exame no outcome do paciente, num hospital público terciário no Reino Unido. Metodologia: 859 ETTs realizados consecutivamente no mês de Janeiro de 2014, foram revistos por forma a avaliar a sua adequação e foram classificados como adequados, incertos ou inadequados de acordo com as guidelines de 2011. De seguida os registos dos pacientes foram revistos com o intuito de avaliar o impacto clinico dos ETTs e foram classificados de acordo com uma das 3 seguintes categorias: (1) alteração ativa dos cuidados – por continuação ou descontinuação dos cuidados como resultado do ETT, (2) continuação dos cuidados – sem continuação ou descontinuação dos cuidados, mas comunicação ao paciente dos resultados do ETT, (3) sem alteração dos cuidados – os cuidados ao paciente já estavam a ser aplicados previamente ao resultado do ETT, causa de sintomas já estabelecida no momento da requisição para exame, exame prévio explicativo dos sintomas e sem indicação aguda para novo ETT, terapêutica não alterada ou inexistência de documentação relativa aos achados ecocardiográficos. Pacientes cujos registos não se encontravam disponíveis foram excluídos (259). Todas as classificações foram avaliadas por uma cardiologista independente, sem relação direta com o estudo. Resultados: A nossa amostra apresentou uma média de idades de 63 ± 17 anos, com uma equilíbrio de géneros. A maioria dos exames foi solicitada em contexto de ambulatório (81,4%), pela Cardiologia (50,3%) e pela Medicina Geral e Familiar (13,4%). Relativamente aos achados ecocardiográficos dos exames, 7,6% demonstraram disfunção sistólica do ventrículo esquerdo moderada a grave, 4,0% revelaram doença valvular grave e 5,1% hipertensão pulmonar significativa. Em relação à adequação dos pedidos para ETTs, 76,5% foram adequados, 7,1% inadequados e 12,6% incertos. Relativamente ao impacto clínico dos ETTs, 42,7% dos exames revelaram uma alteração ativa nos cuidados, 15,6% mostraram uma continuação dos cuidados e 11,5% demonstraram não haver alteração nos cuidados. A idade (P=0,05), o contexto de atendimento (P<0,01) e o pedido realizado pela especialidade medicina geral e familiar (MGF) (P=0,02) foram os preditores mais importantes de uma alteração ativa nos cuidados. Numa perspectiva de prestação de cuidados a uma população mais idosa, o contexto de atendimento, a presença de achados ecocardiográficos significativos e a não alteração dos cuidados apresentam uma relação significativa com a idade. Conclusões: Os dados demonstram que quase 8 em cada 10 ETTs foram considerados adequados e que 4 em cada 10 exames não apresentaram alteração ativa dos cuidados.

Evaluation of the performance of pharmacists in terms of providing health assistance at a university hospital

OBJETIVE: This study aimed to assess the practices of pharmacists in Hospital Care. Method - we interviewed 20 pharmacists from the Pharmacy Division by applying a structured instrument, in September 2005. This instrument addressed aspects related to the main activities at the Hospital Pharmacy, which were assessed according to indicators organized into five areas: sector management, hospital pharmacotechniques, committee activities, information and pharmacotherapeutic follow-up, as well as teaching and research activities.RESULTS: the Pharmacy Division considered all structural aspects under analysis as essential for the good development and application of its services. We found that some essential services, such as the Medication Information Service and Pharmacotherapeutic Follow-up, were absent. Pharmacist professionals were dissatisfied about human resource and physical structure dimensioning, and they presented as not very active in terms of Pharmaceutical Care.CONCLUSION: Results indicate that care is still centered on the drug, with few clinical activities. We suggest reformulations in service management, particularly in the management of pharmacists.

Noninvasive positive-pressure ventilation in clinical practice at a large university-affiliated Brazilian hospital

OBJECTIVES: To describe noninvasive positive-pressure ventilation use in intensive care unit clinical practice, factors associated with NPPV failure and the associated prognosis. METHODS: A prospective cohort study. RESULTS: Medical disorders (59%) and elective surgery (21%) were the main causes for admission to the intensive care unit. The main indications for the initiation of noninvasive positive-pressure ventilation were the following: post-extubation, acute respiratory failure and use as an adjunctive technique to chest physiotherapy. The noninvasive positive-pressure ventilation failure group was older and had a higher Simplified Acute Physiology Score II score. The noninvasive positive-pressure ventilation failure rate was 35%. The main reasons for intubation were acute respiratory failure (55%) and a decreased level of consciousness (20%). The noninvasive positive-pressure ventilation failure group presented a shorter period of noninvasive positive-pressure ventilation use than the successful group [three (2-5) versus four (3-7) days]; they had lower levels of pH, HCO3 and base excess, and the FiO(2) level was higher. These patients also presented lower PaO2:FiO2 ratios; on the last day of support, the inspiratory positive airway pressure and expiratory positive airway pressure were higher. The failure group also had a longer average duration of stay in the intensive care unit [17 (10-26) days vs. 8 (5-14) days], as well as a higher mortality rate (9 vs. 51%). There was an association between failure and mortality, which had an odds ratio (95% CI) of 10.6 (5.93 - 19.07). The multiple logistic regression analysis using noninvasive positive pressure ventilation failure as a dependent variable found that treatment tended to fail in patients with a Simplified Acute Physiology Score II >= 34, an inspiratory positive airway pressure level >= 15 cmH2O and pH<7.40. CONCLUSION: The indications for noninvasive positive-pressure ventilation were quite varied. The failure group had a longer intensive care unit stay and higher mortality. Simplified Acute Physiology Score II >= 34, pH<7.40 and higher inspiratory positive airway pressure levels were associated with failure.

Frequency and predictors of symptomatic intracranial hemorrhage after intravenous thrombolysis for acute ischemic stroke in a Brazilian public hospital

OBJECTIVE: Scarce data are available on the occurrence of symptomatic intracranial hemorrhage related to intravenous thrombolysis for acute stroke in South America. We aimed to address the frequency and clinical predictors of symptomatic intracranial hemorrhage after stroke thrombolysis at our tertiary emergency unit in Brazil. METHOD: We reviewed the clinical and radiological data of 117 consecutive acute ischemic stroke patients treated with intravenous thrombolysis in our hospital between May 2001 and April 2010. We compared our results with those of the Safe Implementation of Thrombolysis in Stroke registry. Univariate and multiple regression analyses were performed to identify factors associated with symptomatic intracranial transformation. RESULTS: In total, 113 cases from the initial sample were analyzed. The median National Institutes of Health Stroke Scale score was 16 (interquartile range: 10-20). The median onset-to-treatment time was 188 minutes (interquartile range: 155-227). There were seven symptomatic intracranial hemorrhages (6.2%; Safe Implementation of Thrombolysis in Stroke registry: 4.9%; p = 0.505). In the univariate analysis, current statin treatment and elevated National Institute of Health Stroke Scale scores were related to symptomatic intracranial hemorrhage. After the multivariate analysis, current statin treatment was the only factor independently associated with symptomatic intracranial hemorrhage. CONCLUSIONS: In this series of Brazilian patients with severe strokes treated with intravenous thrombolysis in a public university hospital at a late treatment window, we found no increase in the rate of symptomatic intracranial hemorrhage. Additional studies are necessary to clarify the possible association between statins and the risk of symptomatic intracranial hemorrhage after stroke thrombolysis.

Current practices in the management of patients with ureteral calculi in the emergency room of a university hospital

OBJECTIVE: Urinary lithiasis is a common disease. The aim of the present study is to assess the knowledge regarding the diagnosis, treatment and recommendations given to patients with ureteral colic by professionals of an academic hospital. MATERIALS AND METHODS: Sixty-five physicians were interviewed about previous experience with guidelines regarding ureteral colic and how they manage patients with ureteral colic in regards to diagnosis, treatment and the information provided to the patients. RESULTS: Thirty-six percent of the interviewed physicians were surgeons, and 64% were clinicians. Forty-one percent of the physicians reported experience with ureterolithiasis guidelines. Seventy-two percent indicated that they use noncontrast CT scans for the diagnosis of lithiasis. All of the respondents prescribe hydration, primarily for the improvement of stone elimination (39.3%). The average number of drugs used was 3.5. The combination of nonsteroidal anti-inflammatory drugs and opioids was reported by 54% of the physicians (i. e., 59% of surgeons and 25.6% of clinicians used this combination of drugs) (p = 0.014). Only 21.3% prescribe alpha blockers. CONCLUSION: Reported experience with guidelines had little impact on several habitual practices. For example, only 21.3% of the respondents indicated that they prescribed alpha blockers; however, alpha blockers may increase stone elimination by up to 54%. Furthermore, although a meta-analysis demonstrated that hydration had no effect on the transit time of the stone or on the pain, the majority of the physicians reported that they prescribed more than 500 ml of fluid. Dipyrone, hyoscine, nonsteroidal anti-inflammatory drugs, and opioids were identified as the most frequently prescribed drug combination. The information regarding the time for the passage of urinary stones was inconsistent. The development of continuing education programs regarding ureteral colic in the emergency room is necessary.
