Dehydroepiandrosterone, its sulfate and cognitive functions

To present a review of cross-sectional and longitudinal studies that investigate the relationship between the hormones Dehydroepiandrosterone (DHEA) and Dehydroepiandrosterone sulfate (DHEA-S) and cognition. Methods: The cognition items included in this review were global cognitive function, memory, attention, executive function, intelligence, perception and visuospatial ability. A systematic review was proceeded using three databases: PubMed, ISI Web of Science, and PsycINFO. Results: Two thousand fifty five references about cognition and hormones were found; 772 duplicated references were excluded, resulting in 1.283 references to be evaluated. According to exclusion and inclusion criteria, 25 references were selected. A positive correlation between DHEA-S blood levels and global cognition was found in women and men. Other positive correlations between DHEA-S and working memory, attention and verbal fluency were found only in women. The DHEA effect on cognition is limited to one study conducted among young men with high-doses

Major depression and hormone suppression: response with nortriptiline

BACKGROUND: The relevance of this clinical case report is to emphasize the importance of the use of nortryptiline for major depression after endometriosis treatment. OBJECTIVE: To describe by a case report the relationship between treatment for endometriosis and psychiatric disorders. We will also describe the therapeutic response to nortriptyline. METHODS: Psychiatric interview and periodical clinical psychiatric evaluation for the treatment of a patient in the Outpatient Unit of the Institute of Psychiatry of the Federal University of Rio de Janeiro. RESULTS: An outpatient, fifty-five year-old woman with major depression treated in the Psychiatric Institute of Federal University of Rio de Janeiro. She was being treated for endometriosis with goserelin for hormone suppression when she started to complain of depressive and anxiety symptoms. The patient did not improve with 20 mg/day of fluoxetine for 8 weeks. She improved after 2 weeks using 25 mg/day of nortryptiline. The improvement persisted during our 16 weeks follow-up. CONCLUSION: Although only sertraline has its efficacy demonstrated for depressive symptoms associated with ovarian suppression, in this case nortriptyline was efficient too. We observed the necessity of more studies about this topic in order to better evaluate other therapeutic options.CONTEXTO: A relevância da descrição deste caso clínico é demonstrar a importância do uso de nortriptilina em um caso de depressão maior pós-tratamento para endometriose. OBJETIVO: Demonstrar as relações entre o tratamento para endometriose e os transtornos psiquiátricos e o resultado terapêutico que obtivemos com o uso da nortriptilina. MÉTODOS: Entrevista psiquiátrica e avaliação clínica psiquiátrica periódica de uma paciente em tratamento no ambulatório do Instituto de Psiquiatria da Universidade Federal do Rio de Janeiro. RESULTADOS: Mulher de 25 anos que, após início de supressão hormonal com goserelina para o tratamento da endometriose, passou a apresentar sintomatologia depressiva e ansiosa proeminente. Sem melhora com o uso de 20 mg/dia de fluoxetina por 8 semanas, foram prescritos 25 mg/dia de nortriptilina com boa resposta clínica em 2 semanas, mantendo a melhora depois de 16 semanas. CONCLUSÃO: Apesar de apenas a sertralina ter sua eficácia demonstrada na melhora dos sintomas depressivos associados à supressão ovariana, neste caso a nortriptilina demonstrou-se eficaz. Observamos a necessidade de estudos crescentes na área a fim de avaliar outras opções terapêuticas

Histone Methylation/Demethylation Inhibition Modulates Sleep

Histone methylation/demethylation plays an important modulatory role in chromatin restructuring, RNA transcription and is essential for controlling a plethora of biological processes. Due to many human diseases have been related to histone methylation/demethylation, several compounds such as 3-deazaneplanocin A (DZNep) or 3-((6-(4,5-Dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoic acid; N-[2-(2-pyridinyl)-6-(1,2,4,5-tetrahydro-3H-3-benzazepin-3-yl)-4-pyrimidinyl]-b-Alanine (GSK-J1), have been designed to inhibit histone methylase or suppress histone demethylase, respectively. In the present study, we investigated the effects on the sleep-wake cycle and sleep-related neurochemical levels after systemic injections of DZNep or GSK-J1 given during the light or dark phase in rats. DZNep dose-dependently (0.1, 1.0, or 10 mg/kg, i.p.) prolonged wakefulness (W) duration while decreased slow wave sleep (SWS) and rapid eye movement sleep (REMS) time spent during the lights-on period with no changes observed in dark phase. In opposite direction, GSK-J1 (0.1, 1.0, or 10 mg/kg, i.p.) injected at the beginning of the lights-on period induced no statistical changes in W, SWS, or REMS whereas if administered at darkness, we found a diminution in W and an enhancement in SWS and REMS. Finally, brain microdialysis experiments in freely moving animals were used to evaluate the effects of DZNep or GSK-J1 treatments on contents of sleep-related neurochemicals. The results showed that DZNep boosted extracellular levels of dopamine, norepinephrine, epinephrine, serotonin, adenosine, and acetylcholine if injected at the beginning of the lights-on period whereas GSK-J1 exerted similar outcomes but when administered at darkness. In summary, DZNep and GSK-J1 may control the sleep-wake cycle and sleep-related neurochemicals through histone methylation/demethylation activity

Análise de qualidade de vida associada a aplicação de protocolo de marcha e equilíbrio em pacientes com parkinson / Analysis of quality of life associated with the application of protocol of march and balance in patients with parkinson

Introdução: A doença de Parkinson (DP) é a segunda doença neurodegenerativa mais frequente no envelhecimento da população, onde é reconhecida por degeneração de neurônios dopaminérgicos na substancia negra. Como características patológicas, a DP possui sintomas como bradicinesia, instabilidade postural, rigidez e tremor de repouso. Objetivo: Avaliar os efeitos da aplicação de protocolo de equilíbrio e marcha na qualidade de vida de indivíduos com a doença de Parkinson. Metodologia: Este estudo trata-se de uma série de casos, realizada com 4 pacientes diagnosticados com Doença de Parkinson (DP), tendo idades variadas entre 50 a 78. A coleta foi iniciada após a leitura e assinatura do Termo de Consentimento Livre e Esclarecido (TCLE) (CAAE: 55502916.8.0000.5162), logo após foi realizada uma entrevista com coleta dos dados pessoais e feita à aplicação das escalas de avaliação. Foram avaliados através da Escala UPDRS, PDQ39, Tinetti e Timed Up and Go, e posteriormente foram submetidos a 7 dias consecutivos a um protocolo de marcha e equilíbrio, seguidos de uma reavaliação. Resultados: Todos os participante se favoreceram nos aspectos gerais da doença visto pelo UPDRS e obtiveram melhor tempo no Timed Up and Go, além de melhoras qualitativas na qualidade de vida. Conclusão: Conclui-se que o protocolo de marcha e equilíbrio para a melhora da qualidade de vida de pacientes com DP foi eficaz

Fighting obesity: non-pharmacological interventions

The abnormal or excessive fat accumulation that impairs health is one of the criteria that fulfills obesity. According to epidemiological data, obesity has become a worldwide public health problem that in turn would trigger additional pathologies such as cardiorespiratory dysfunctions, cancer, gastrointestinal disturbances, depression, sleep disorders, just to mention a few.info:eu-repo/semantics/publishedVersio
