Contribution of astrocytes and macrophage migration inhibitory factor to immune-mediated canine encephalitis caused by the distemper virus.

Macrophage migration inhibitory factor (MIF) is a pleiotropic cytokine that is produced by many cell types in situations of homeostasis or disease. One of its functions is to act as a proinflammatory molecule. In humans, several studies have shown that MIF levels become elevated in the serum, urine, cerebrospinal fluid and tissues of patients with chronic inflammatory diseases (systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, sepsis, atheromas, diabetes and cancer). In dogs, distemper is a viral infectious condition that may lead to demyelination and inflammation in the central nervous system (CNS). In addition to the action of the virus, the inflammatory process may give rise to lesions in the white matter. Therefore, the objectives of the present study were to evaluate the role of MIF in the encephalitis that the canine distemper virus causes and to compare this with immunodetection of major histocompatibility complex-II (MHC-II), CD3 T lymphocytes, MMP-9 and glial fibrillary acidic protein (GFAP; astrocytes) in demyelinated areas of the encephalon, in order to ascertain whether these findings might be related to the severity of the encephalic lesions. To this end, a retrospective study on archived paraffinized blocks was conducted, in which 21 encephala from dogs that had been naturally infected with the canine distemper virus (infected group) and five from dogs that had been free from systemic or CNS-affecting diseases (control group) were used. In the immunohistochemical analysis on the samples, the degree of marking by GFAP, MHC-II, MMP-9 and MIF was greater in the demyelinated areas and in the adjacent neuropil, and this was seen particularly in astrocytes. Detection of CD3 was limited to perivascular cuffs. In areas of liquefactive necrosis, Gitter cells were positive for MMP-9, MIF and MHC-II. Hence, it was concluded that activated astrocytes influenced the afflux of T lymphocytes to the encephalon (encephalitis). In the more advanced phases, activated phagocytes in the areas of liquefactive necrosis (Gitter cells) continued to produce inflammatory mediators even after the astrocytes in these localities had died, thereby worsening the encephalic lesions. Distemper virus-activated astrocytes and microglia produce MIF that results in proinflammatory stimulus on glial cells and brain-infiltrating leukocytes. Therefore, the effect of the inflammatory response is potentiated on the neuropil, resulting in neurological clinical signs.

Multiprofessional Treatment of High Blood Pressure in Very Elderly Patients.

BACKGROUND: As the world population ages, patients older than 80 years, known as very elderly, are more frequently found. There are no studies in this age group aimed at analyzing the multidisciplinary intervention in the treatment of systemic arterial hypertension (SAH) and some comorbidities. OBJECTIVES: To assess the effect of a multidisciplinary approach in very elderly hypertensives cared for at a specialized service. METHODS: Longitudinal retrospective cohort study in a multidisciplinary service specialized in the SAH treatment in the Brazilian West-Central region. Patients aged 80 years and older by June 2015 were included. Data from the first (V1) and last visit (Vf) were assessed. Anthropometric variables, blood pressure (BP), renal function, pharmacological treatment, lifestyle, comorbidities and cardiovascular events were studied, comparing data from V1 and Vf. Controlled BP was defined as systolic blood pressure (SBP) lower than 140 mm Hg and diastolic blood pressure (DBP) lower than 90 mm Hg. Statistical analyses were performed with SPSSR software, version 21.0. Values of p<0,05 were considered significant. RESULTS: Data of 71 patients were assessed with a mean follow-up time of 15,22 years. Their mean age at V1 was 69.2 years, and, at Vf, 84.53 years, and 26.8% of them were males. There was a significant reduction in mean SBP (157.3 x 142.1 mm Hg; p<0.001) and DBP (95.1 x 77.8 mm Hg; p<0.001), with an increase in BP control rates from V1 to Vf (36.6 x 83.1%; p<0.001). The number of antihypertensive drugs used increased (1.49 x 2.85; p<0.001), with an increase in the use of angiotensin-converting enzyme inhibitors (22.5 x 46.5%; p=0.004), angiotensin II receptor blockers (4.2 x 35.2%; p<0.001) and calcium-channel blockers (18.3 x 67.6%; p<0.001). There was a reduction in total cholesterol (217.9 x 191 mg/dL; p<0.001) and LDL-cholesterol (139.6 x 119.0 mg/dL; p<0.001), but worsening of the glomerular filtration rate (62.5 x 45.4 mL/min; p<0.001). CONCLUSION: The multidisciplinary intervention in very elderly hypertensives increased BP control rate, with optimization of the pharmacological treatment.

Adaptive Immune Response Impairs the Efficacy of Autologous Transplantation of Engineered Stem Cells in Dystrophic Dogs.

Duchenne muscular dystrophy is the most common genetic muscular dystrophy. It is caused by mutations in the dystrophin gene, leading to absence of muscular dystrophin and to progressive degeneration of skeletal muscle. We have demonstrated that the exon skipping method safely and efficiently brings to the expression of a functional dystrophin in dystrophic CD133+ cells injected scid/mdx mice. Golden Retriever muscular dystrophic (GRMD) dogs represent the best preclinical model of Duchenne muscular dystrophy, mimicking the human pathology in genotypic and phenotypic aspects. Here, we assess the capacity of intra-arterial delivered autologous engineered canine CD133+ cells of restoring dystrophin expression in Golden Retriever muscular dystrophy. This is the first demonstration of five-year follow up study, showing initial clinical amelioration followed by stabilization in mild and severe affected Golden Retriever muscular dystrophy dogs. The occurrence of T-cell response in three Golden Retriever muscular dystrophy dogs, consistent with a memory response boosted by the exon skipped-dystrophin protein, suggests an adaptive immune response against dystrophin.

The natural history of cardiovascular risk factors in health professionals: 20-year follow-up.

BACKGROUND: The knowledge of the presence and evolution of cardiovascular risk factors in young people may significantly contribute to actions to modify the natural history of these risks and prevent the onset of cardiovascular disease. OBJECTIVES: To assess the presence and evolution of cardiovascular risk factors in health professionals over a 20-year period. METHODS: A group of individuals was evaluated when they first started graduate programs in medicine, nursing, nutrition, dentistry, and pharmacy, and 20 years later. Data obtained in the two phases were compared. Questionnaires about hypertension, diabetes, hypercholesterolemia, family history of early-onset cardiovascular disease, smoking, alcohol consumption, and sedentary lifestyle were administered. Cholesterol, blood glucose, blood pressure, weight, height, and body mass index (BMI) were measured. RESULTS: Of the 281 individuals (62.9 % women; mean age 19.7 years) initially analyzed, 215 (59.07 % women; mean age 39.8 years) were analyzed 20 years later. An increase in mean values of systolic (111.6 vs 118.7 mmHg- p < 0.001) and diastolic blood pressure (71 vs 77.1 mmHg - p < 0.001), cholesterol (150.1 vs 182.4 mg/dL - p < 0.001), blood glucose (74.3 vs 81.4 mg/dL - p < 0.001) and BMI (20.7 vs 23.7 kg/m(2) - p = 0.017) was observed. Despite the decrease of sedentarism (50.2 vs 38.1 % - p = 0.015), the prevalence of hypertension (4.6 vs 18.6 % - p < 0.001), excessive weight (8.2 vs 32.1 % - p < 0.001), hypercholesterolemia (7.8 vs 24.2 % - p < 0.001), and alcohol consumption (32.7 vs 34.9 % - p = 0.037) increased. There was no change in the prevalence of smoking. CONCLUSION: Health professionals presented an increase in systolic and diastolic blood pressure, blood glucose, body mass index, and cholesterol over the 20-year study period. Regarding the prevalence of cardiovascular risk factors, increased blood pressure, overweight, hypercholesterolemia and alcohol consumption, and a decrease in sedentary lifestyle were observed.

INTRODUCTION: Hypertensive patients may have compromised quality of life (QoL) and health-related quality of life (HRQoL) because of arterial hypertension (AH) and for possible adverse effects of treatment. Physical, aerobic and resistance exercises, improve cardiorespiratory and neuromuscular performance, but there is little evidence about their effects on QoL, HRQoL and functional capacity (FC) in hypertensive women. OBJECTIVE: To evaluate and compare the effects of aerobic and resistance training on QoL, HRQoL and functional capacity in hypertensive. METHODS: A randomized, blinded clinical trial, with a total of 18 exercise sessions. Hypertensive women receiving drug treatment, non participant in exercise programs, with 50 years of age or more, which did not show arrhythmias and/or ischemic changes on ergometric testing (Bruce protocol) were included. The sample was randomized as follows: aerobic group (AG) (n=21) and resistance group (RG) (n=20). AG intensity: mild to moderate (Borg Scale adapted); RG: up to 50-65% of 1 MR. Two series of 12 to 15 repetitions. Before and after the intervention the WHOQOL-BREF and SF-36 (HEQOL) questionnaires were applied and the 6-minute walk test (6`MWT) was performed to evaluate the FC. Statistics: Shapiro-Wilk, Student t, Fisher, Mann-Whitney U and Wilcoxon tests. Level of significance: p<0.05. RESULTS: The groups were initially homogeneous in clinical, anthropometric, sociodemographic and functional aspects (p>0.05). After the intervention, there was significant improvement in all domains of WHOQOL-bref in AG, and in RG an improvement of the physical domain was found. In the SF-36, there was significant improvement in seven of eight domains in both AG and RG. Functional capacity: improvement was found in both groups (p<0.001). CONCLUSION: The two types of training improved QoL and functional capacity, and depending on the objectives established, both can be effective. .

FUNDAMENTO: Segundo a Organização Mundial de Saúde (OMS), as doenças cardiovasculares (DCV) são responsáveis por 16,7 milhões de mortes/ano. Evidências mostram que as DCV resultam da interação entre fatores de risco variados, presentes desde a infância. OBJETIVO: Verificar, em profissionais da área médica, a presença e evolução de alguns fatores de risco cardiovasculares (FRCV) em um intervalo de 15 anos. MÉTODOS: Analisamos um grupo de indivíduos ao ingressar na faculdade de medicina e repetimos a análise 15 anos depois, comparando os dados encontrados. Utilizamos questionários sobre FRCV (hipertensão arterial sistêmica (HAS), diabete melito (DM), dislipidemia e história familiar de DCV precoce, tabagismo, etilismo e sedentarismo). O colesterol, a glicemia, a PA, o peso, a altura, o índice de massa corpórea (IMC) foram determinados. RESULTADOS: Comparamos 100 indivíduos (sendo 64,0 por cento homens com idade média de 19,9 anos), com os 72 (sendo 62,5 por cento homens, 34,8 anos) incluídos 15 anos após. Houve aumento na prevalência de HAS (6,0 por cento vs 16,7 por cento, p = 0,024), excesso de peso (9,0 por cento vs 26,4 por cento, p = 0,002) e dislipidemia (4,0 por cento vs 19,14 por cento, p = 0,002). Os demais FRCV não se modificaram. Na análise dos valores de pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), colesterol, glicemia e IMC, encontramos elevação na média de todas variáveis (p < 0,05). Houve correlação positiva entre valores de PAS, PAD, IMC e glicemia no intervalo de tempo avaliado (p < 0,05). CONCLUSÃO: Em profissionais da área médica, encontramos elevação na PAS, PAD, glicemia, IMC e colesterol em 15 anos. Na análise da prevalência de FRCV, houve aumento de hipertensão arterial, excesso de peso e dislipidemia.

BACKGROUND: According to the World Health Organization (WHO), cardiovascular diseases (CVD) account for 16.7 million deaths per year. Evidence shows that CVD result from the interaction of multiple risk factors that are present from childhood. OBJECTIVE: To evaluate the presence and evolution of several cardiovascular risk factors (CVRF) among medical professionals, in a period of 15 years. METHODS: We analyzed a group of individuals when they entered medical school, and repeated the analysis after 15 years, comparing the data found. We used CVRF questionnaires (systemic arterial hypertension (SAH); diabetes mellitus (DM); dyslipidemia and family history of premature CVD; smoking habit; alcoholism; and sedentary lifestyle). Cholesterol, blood glucose, BP, weight, height, body mass index (BMI) values were determined. RESULTS: We compared 100 subjects (64.0 percent men with a mean age of 19.9 years) with a total of 72 subjects (62.5 percent men, 34.8 years) that were included in the study 15 years later. There was an increase in the prevalence of hypertension (6.0 percent vs 16.7 percent, p = 0.024), overweight (9.0 percent vs 26.4 percent, p = 0.002), and dyslipidemia (4.0 percent vs 19.14 percent, p = 0.002). The other CVRF remained unchanged. Analyzing the values of systolic blood pressure (SBP); diastolic blood pressure (DBP); cholesterol; glucose; and BMI, we found an increase in the mean values of all variables (p < 0.05). We observed a positive correlation between the values of SBP, DBP, BMI, and blood glucose measured in the time interval (p < 0.05). CONCLUSION: Among medical professionals, there was an elevation in SBP, DBP, glucose, BMI, and cholesterol values in 15 years. In the CVRF prevalence analysis, we found an increase in the prevalence of hypertension, overweight, and dyslipidemia.

Efeitos da atividade da fosfolipase A2 nos receptores dopaminérgicos: implicações para a esquizofrenia / Effects of phospholipase A2 on dopamine receptors: implications to schizophrenia

Um aumento da atividade da PLA2 e alterações do sistema dopaminérgico tem sido descrito em esquizofrenia. No presente estudo, foram investigados os efeitos da atividade da PLA2 sobre os receptores D1 e D2 em cérebro post mortem de 10 sujeitos. Foi encontrado que a PLA2GVI é responsável por 85% do total de atividade da PLA2 no cérebro. A estimulação da PLA2GVI (por EDTA) aumentou a afinidade de D1 em estriado e em CPF e diminuiu a afinidade de D2 em estriado. A inibição da PLA2GVI (por BEL) diminuiu a afinidade de D1 em estriado, e em CPF e CT. A estimulação da PLA2GVI resultou em aumento na densidade de D1 em CPF e CT, e de D2 em estriado. Uma elevação da PLA2 em esquizofrenia poderia contribuir para a biologia da doença através de alterações na neurotransmissão dopaminérgica.

Increased PLA2 activity and dopaminergic alterations have been described in schizophrenia. In the present study it was investigated the effects of PLA2 activity on D1 and D2 receptors in post mortem brain of 10 subjects. It was found that PLA2GVI corresponds to 85% of all PLA2 activity in the brain. The stimulation of PLA2GVI (by EDTA) increased D1 affinity in striatum and in PFC, and decreased D2 affinity in striatum. Conversely, the inhibition of PLA2GVI (using BEL) decreased D1 affinity in striatum, PFC and TC. The stimulation of PLA2GVI increased D1 density in PFC and TC, as well as the D2 density in striatum. The increased PLA2 activity in schizophrenia may contribute to the biology of the disease through alterations in dopaminergic neurotransmission.
