Pneumococcal meningitis is a life-threatening disease characterized by an acute infection affecting the pia matter, arachnoid and subarachnoid space. The intense inflammatory response is associated with a significant mortality rate and neurologic sequelae, such as, seizures, sensory-motor deficits and impairment of learning and memory. The aim of this study was to evaluate the effects of acute and extended administration of cannabidiol on pro-inflammatory cytokines and behavioral parameters in adult Wistar rats submitted to pneumococcal meningitis. Male Wistar rats underwent a cisterna magna tap and received either 10μl of sterile saline as a placebo or an equivalent volume of S. pneumoniae suspension. Rats subjected to meningitis were treated by intraperitoneal injection with cannabidiol (2.5, 5, or 10mg/kg once or daily for 9 days after meningitis induction) or a placebo. Six hours after meningitis induction, the rats that received one dose were killed and the hippocampus and frontal cortex were obtained to assess cytokines/chemokine and brain-derived neurotrophic factor levels. On the 10th day, the rats were submitted to the inhibitory avoidance task. After the task, the animals were killed and samples from the hippocampus and frontal cortex were obtained. The extended administration of cannabidiol at different doses reduced the TNF-α level in frontal cortex. Prolonged treatment with canabidiol, 10mg/kg, prevented memory impairment in rats with pneumococcal meningitis. Although descriptive, our results demonstrate that cannabidiol has anti-inflammatory effects in pneumococcal meningitis and prevents cognitive sequel.
This study evaluated the association of mood disorders, suicidal ideation and the quality of life in patients with type 2 diabetes. We used a case-control study employing 996 patients suffering with type 2 diabetes (using insulin for over 1 year), and 2.145 individuals without diabetes. The groups were then used to evaluate the presence of different mood disorders and suicidal ideation, beyond quality of life. In addition to this, fasting glucose and glycosylated hemoglobin (Hb1C) were also evaluated. The data were analyzed using the Pearson chi-squared test, logistic regression, ANCOVA and Student's t-tests. We showed an association between type 2 diabetes and depressive episodes (adjusted OR = 1.8, CI 95 % 1.7-2.0, p < 0.001), recurrent depressive episodes (adjusted OR = 2.4, CI 95 % 2.2-2.6, p < 0.001), dysthymia (adjusted OR = 5.2, CI 95 % 4.9-5.5, p < 0.001), mood disorder with psychotic symptoms (adjusted OR = 2.5, CI 95 % 1.5-3.4, p < 0.001) and suicidal ideation (adjusted OR = 3.6, CI 95 % 2.5-4.8, p < 0.001, light; adjusted OR = 4.6, CI 95 % 1.5-7.7, p < 0.01, moderate and severe). The recurrent depression (OR = 1.3, CI 95 % 1.1-1.7, p < 0.05) and psychotic symptoms (OR = 4.1, CI 95 % 1.1-15.1, p < 0.05) were associated with higher levels of Hb1C. Dysthymia was associated with high blood glucose (OR = 1.6, CI 95 % 1.1-2.5, p < 0.05). Patients had lower mean scores in the following domains: physical [36.5 (13.6) × 56.0 (4.9), p < 0.001)], psychological [42.6 (8.6) × 47.9 (8.6), p < 0.001] and environmental [40.0 (8.6) × 49.3 (8.3), p < 0.001], but had higher scores in the area of social relations [50.2 (16.9) × 35.7 (27.9), p < 0.001]. The data demonstrated a worse quality of life, a high comorbidity of type 2 DM with depressive disorders and suicidal ideation. In addition, the poor control of DM is associated with the severity of mood disorders.
ResumoCom a valorização da estética dentária, aliada à atual filosofia conservadora da Odontologia, as técnicas de clareamento apresentaram uma evolução clínica considerável. A alteração de cor dental vem sendo um dos problemas estéticos mais procurados pelos pacientes no consultório odontológico. O emprego das técnicas clareadoras caseiras e em consultório, quando corretamente executadas, possibilitam resultados estéticos satisfatórios. O objetivo deste estudo foi apresentar as técnicas de clareamento dental (caseiro e consultório), por meio de uma revisão narrativa de literatura. Realizou-se uma discussão dos principais procedimentos adotados, comparando-se os efeitos a curto e longo prazo, vantagens, desvantagens e efeitos colaterais. Nesses tratamentos, os principais agentes clareadores utilizados são o peróxido de carbamida e o peróxido de hidrogênio. Disponíveis em diversas concentrações, são responsáveis por promover resultados satisfatórios no branqueamento dos dentes, cabendo ao cirurgião-dentista efetuar uma análise do perfil do paciente, com vistas à escolha da melhor alternativa de tratamento. Mediante revisão apresentada, ambos os tratamentos foram semelhantes. No entanto, algumas peculiaridades devem ser observadas: para pacientes com sensibilidade dental, o mais indicado é o clareamento caseiro; em pacientes com retração gengival, o mais indicado é o de consultório. Descritores: Clareamento dental • Peróxidos • Peróxido de hidrogênio. AbstractWith the appreciation of aesthetic dentistry, combined with the current conservative philosophy of dentistry, the bleaching techniques had considerable clinical progress. The dental discoloration comes being one of the most popular aesthetic problems by patients in the dental office. The use of at-home and in-office bleaching techniques, when properly executed, enable satisfactory esthetic results. The aim of this study was presenting the tooth bleaching techniques (at-home and in-office), through a literature narrative review. It was held a discussion of the main procedures adopted, by comparing the short-term and long-term effects, advantages, disadvantages and side effects. At these treatments, the main used bleaching agents are carbamide peroxide and hydrogen peroxide. Available in varying concentrations, are responsible for promoting satisfactory results in whitening teeth, leaving the dentist perform an analysis of the patient's profile, with a view to choosing the best alternative treatment. Upon review presented, both treatments were similar. However, some peculiarities must be observed: for patients with tooth sensitivity, the most suitable is the at-home bleaching; in patients with gingival recession, the most suitable is the in-office bleaching.
Pneumococcal meningitis is a serious infection of the central nervous system (CNS) with high fatality rates that causes reduced psychomotor performance, slight mental slowness, impairments in attention executive functions and learning and memory deficiencies. Previously, we demonstrated a correlation between memory impairment and decreased levels of brain-derived neurotropic factor (BDNF) in the hippocampi of rats subjected to pneumococcal meningitis. Emerging evidence demonstrates that histone acetylation regulates neurotrophins; therefore, a potential molecular intervention against cognitive impairment in bacterial meningitis may be the histone deacetylase (HDAC) inhibitor, sodium butyrate, which stimulates the acetylation of histones and increases BDNF expression. In this study, animals received either artificial cerebrospinal fluid as a placebo or a Streptococcus pneumoniae suspension at a concentration of 5 × 10(9) colony-forming units (CFU/mL). The animals received antibiotic treatment as usual and received saline or sodium butyrate as an adjuvant treatment. Ten days after, meningitis was induced; the animals were subjected to open-field habituation and the step-down inhibitory avoidance task. Immediately after these behavioural tasks, the animals were killed, and their hippocampi were removed to evaluate the expression of BDNF, nerve growth factor (NGF) and glial cell line-derived neurotrophic factor (GDNF). In the meningitis group that received saline, the animals presented memory impairment in both behavioural tasks, and hippocampal BDNF and GDNF expression was decreased. Sodium butyrate was able to prevent memory impairment and re-establish hippocampal neurotrophin expression in experimental pneumococcal meningitis.
RESUMO Objetivo Avaliar a prevalência de transtornos ansiosos e fatores associados em uma amostra populacional de idosos do Sul de Santa Catarina. Métodos Estudo transversal com base em dados populacionais, que avaliou 1.021 indivíduos idosos entre 60 e 79 anos. Foram realizadas entrevistas domiciliares para aferição de variáveis sobre transtornos ansiosos, por meio do questionário MINI, dados sociodemográficos, hipertensão arterial sistêmica (HAS), infarto agudo do miocárdio (IAM) e dosagem de colesterol. Resultados As prevalências entre os transtornos ansiosos foram de 22,0% para o transtorno de ansiedade generalizada (TAG); 14,8% para fobia social (FS); 10,5% para transtorno do pânico (TP); e 8,5% para o transtorno obsessivo-compulsivo (TOC). Além disso, 40,5% dos indivíduos apresentaram pelo menos um transtorno de ansiedade. A distribuição dos transtornos foi semelhante nos dois gêneros; TAG foi mais prevalente nos indivíduos de menor escolaridade; TOC foi mais presente em indivíduos casados ou em união estável. Em relação às variáveis clínicas, HAS foi associada à presença de TOC; FS foi associada com IAM; TOC e FS foram associados com HDL > 40 mg/dL. Conclusão Os dados demonstram que os quadros de ansiedade são muito frequentes em idosos da comunidade, se sobrepõem de forma significativa e estão associados a algumas variáveis clínicas cardiovasculares.
Objective: To assess the presence of anxiety disorders and quality of life in patients with insulindependent type 2 diabetes. Methods: Case-control study of 996 patients with type 2 diabetes and 2,145 individuals without diabetes. The sole inclusion criterion for the case group was insulin-dependent type 2 diabetes. We compared the case and control groups for sociodemographic variables, laboratory and clinical data, and presence of anxiety disorders. Quality of life was evaluated using the WHOQOL-BREF instrument, and the prevalence of anxiety disorder was evaluated by the Mini International Neuropsychiatric Interview (MINI). Results: Patients with diabetes had a higher prevalence of generalized anxiety disorder, panic disorder, and obsessive-compulsive disorder. The presence of these disorders in combination with type 2 diabetes was associated with worse quality of life in the physical, social, psychological, and environmental domains. Conclusions: This study demonstrates the importance of diagnosing and treating anxiety disorders in patients with diabetes, so as to prevent more serious complications associated with these comorbidities.
