In the present investigation, ibotenic acid lesion of mediodorsal thalamic nuclei reduced the wakefulness and increased paradoxical sleep, which contradicts the reports from earlier lesion studies in cats. Glutamate excitation of mediodorsal thalamic nuclei produced prolonged wakefulness. The results suggest that the mediodorsal thalamic nuclei augments arousal in the ascending reticular wake promoting pathways in contrast to the earlier reports that mediodorsal thalamic nucleus is involved in generation of slow wave sleep. The present study adds another evidence for the role of thalamus in sleep-wake regulation.

Second generation (atypical) antipsychotics are increasingly being used for treatment of insomnia, but there is little evidence to show long-term efficacy of these medication. https://www.selleckchem.com/products/cc-122.html This follow-up study was designed to assess patients with chronic insomnia who were treated with atypical antipsychotics. In this follow-up study, forty patients with chronic insomnia were evaluated between 2016 and 2018 following after one year of treatment with two atypical antipsychotic drugs of olanzapine and quetiapine in two groups in the sleep disorders research center of Kermanshah University of Medical Science in Iran. The Pittsburgh Sleep Quality Questionnaire (PSQI) and 5 consecutive nights of Actigraphy were utilized to evaluate both subjective and objective measures of sleep quality. Lastly, sleep quality before and after treatment and comparisons of sleep quality between the two groups were performed. Nine male participants comprised olanzapine group (n=22) and six male participants comprised the quetiapine group (n=18). The average age in the olanzapine group was 45.23±10.18 and the average age in the quetiapine group was 46.33±7.99. Results showed total PSQI score improved significantly in both groups (p<0.05), while the actigraphy results showed only significant improvement in sleep quality parameters in the quetiapine group (p<0.05). Two atypical antipsychotics drugs of olanzapine and quetiapine have long-term efficacy in managing chronic insomnia. More improvements in objective sleep quality with quetiapine is promising for patients with chronic insomnia. Further research to evaluate long-term adverse effects of atypical antipsychotic drugs is recommended.

Obstructive sleep apnoea (OSA) is the most common sleep disorder and its prevalence has increased with the obesity pandemic. We aimed to explore the presence of OSA in severe obesity and to evaluate the association of body mass index (BMI) with sleep architecture, cognition, emotional distress and comorbidities in OSA versus non-OSA patients. A sample of 61 patients performed a neuropsychological battery that included tasks of attention, memory, perceptual/visuospatial ability, vocabulary, inhibition, cognitive flexibility and distress symptomatology, before overnight polysomnography. More than half of the sample had OSA. Excessive daytime sleepiness was not a prominent complaint. Sleep architecture was worse in the OSA than in the non-OSA group, and hypertension was increased with OSA, especially in the severe OSA group. A higher BMI was associated with cognitive distress and sleep variables and with type 2 diabetes. The apnoea-hypopnoea index (AHI) was correlated with gender and cognitive measurementsment. Chronic heart failure is associated with changes in sleep pattern and affects quality of sleep among patients with heart failure. Poor sleep has a negative impact on the patients' quality of life, furthermore it compromises cognition and one's self-care practice. Though, factors affecting sleep among heart failure patients have been investigated in developed world, there are limited studies in regards to it in developing countries like Ethiopia. The aim of the study is to assess the level of sleep quality and associated factors among heart failure patients who are on follow up at Jimma Medical Center (JMC). Hospital based cross sectional study was employed among the total sample of 111 chronic heart failure patients admitted to medical ward and having follow up at cardiac center of JMC. The data was collected from April 1 - April 30, 2019 through face-to-face interview by using structured questionnaire. Pittsburg Sleep Quality Index (PSQI) was applied to assess sleep quality. PSQI score <5 refers to tients. Age >65 years and comorbidities are predictors of poor sleep quality in these patients. 65 years and comorbidities are predictors of poor sleep quality in these patients.Substantial evidence suggests that the timing of macronutrient intake affects cardiovascular health. The present study aims to assess the association between the dietary carbohydrate intake (DCI) and the high-sensitivity C-reactive protein (hs-CRP) combined with the implication of the chronotype. Thus, we explored the most recently released National Health and Nutrition Examination Survey (NHANES) data. We analysed data from 5,616 participants of the NHANES in 2015. We selected participants with available data for the DCI, sleep and wake-up time, and the hs-CRP. Chronotypes were categorized according to the sleep times. Binary logistic regression analysis was performed to predict participants with low or high levels of hs-CRP based on the DCI and chronotypes. Moderation analysis was used to investigate the effect of the chronotypes on the DCI-hs-CRP's association. A higher DCI was significantly associated with the higher hs-CRP levels (odds ratio (OR) = 1.36, 95% confidence interval (CI) = [0.9-1.8]). Moderate evening (ME) chronotypes had higher risk for high hs-CRP level (OR = 1.
