Gang Song, Chi-Sang Poon
Decreased noradrenergic excitation of hypoglossal motoneurons during sleep causing hypotonia of pharyngeal dilator muscles is a major contributor to the pathogenesis of obstructive sleep apnea (OSA), a widespread disease for which treatment options are limited. Previous OSA drug candidates targeting various excitatory/inhibitory receptors on hypoglossal motoneurons have proved unviable in reactivating these neurons, particularly during rapid-eye-movement (REM) sleep. To identify a viable drug target, we show that the repurposed α2-adrenergic antagonist yohimbine potently reversed the depressant effect of REM sleep on baseline hypoglossal motoneuron activity (a first-line motor defense against OSA) in rats...

BACKGROUND: The B-RCOPE is a brief measure assessing religious coping. We aimed to assess the psychometric properties of its Greek version in people with and without long-term conditions (LTCs). Associations between religious coping and mental illness, suicidality, illness perceptions, and quality of life were also investigated. METHODS: The B-RCOPE was administered to 351 patients with diabetes, chronic pulmonary obstructive disease (COPD), and rheumatic diseases attending either the emergency department (N = 74) or specialty clinics (N = 302) and 127 people without LTCs...

The C9orf72 mutation was identified as the most frequent genetic cause of frontotemporal dementia (FTD). In light of multiple reports of predominant psychiatric presentations of FTD secondary to C9orf72 mutation, the American Neuropsychiatric Association Committee on Research reviewed all studies on psychiatric aspects of this mutation to identify clinically relevant features for diagnosis. The most common psychiatric presentation is psychosis (21%-56%), with delusions, and/or multimodal hallucinations. Other presentations include late-onset mania and depression with cognitive impairment or catatonia...

Neurocognitive and psychiatric complications are common following cardiac surgery and impact on patient quality of life, recovery from surgery, participation in rehabilitation and long-term mortality. Postoperative cognitive decline, depressive disorders, post-traumatic stress disorder and neurocognitive impairment related to silent brain infarcts have all been linked to the perioperative period of cardiac surgery, and potentially have serious consequences. The accurate assessment of these conditions, particularly in determining the aetiology, and impact on patients is difficult due to the poorly recognised nature of these complications as well as similarities in presentation with postoperative delirium...

STUDY DESIGN: Systematic review. INTRODUCTION AND PURPOSE OF THE STUDY: After traumatic hand injury, extensive physical and psychological adaptation is required following surgical reconstruction. Recovery from injury can understandably be emotionally challenging, which may result in impaired quality of life and delayed physical recovery. However, the evidence base for identifying high-risk patients is limited. METHODS: A PROSPERO-registered literature search of MEDLINE (1946-present), EMBASE (1980-present), PsychInfo, and CINAHL electronic databases identified 5156 results for studies reporting psychological outcomes after acute hand trauma...

INTRODUCTION: Being able to understand other people's emotions and intentions is crucial for social interactions and well-being. Deficits in theory of mind (ToM) functioning hamper this ability and have been observed in depression and other neuropsychiatric disorders. However, results of previous research in depression have been inconclusive, possibly due to the presence of comorbid disorders and the disregarding of other modulating factors. METHODS: Thirty-eight patients with a major depressive disorder (MDD) and forty healthy matched controls were assessed with a ToM task using animated triangles...

Epidemiological evidence suggests that consumption of flavonoids (usually via fruits and vegetables) is associated with decreased risk of developing depression. One plausible explanation for this association is the well-documented beneficial effects of flavonoids on executive function (EF). Impaired EF is linked to cognitive processes (e.g., rumination) that maintain depression and low mood; therefore, improved EF may reduce depressionogenic cognitive processes and improve mood. Study 1: 21 young adults (18-21 years old) consumed a flavonoid-rich blueberry drink and a matched placebo in a counterbalanced cross-over design...

Transcranial magnetic stimulation is a neurostimulation technique which has the potential to serve as a unique research tool for investigating a wide variety of fields in cognitive neuroscience. TMS has been approved by the FDA to serve as a treatment to depression and has also been used to evaluate its effects among several conditions such as Alzheimer, Parkinson disease, chronic pain and stroke. High frequency TMS has been previously used with the intention to measure and modulate the negative effects of sleep deprivation in cognitive performance, but there is no consensus about the ideal protocol yet...

OBJECTIVE: This study was designed to evaluate whether or not chronic Rosa Canina (RC) extract administration could improve recognition memory and depressive-like behaviour in diabetic mice. MATERIALS AND METHODS: Seventy-five (75) male Albino mice (25-30 g) were randomly divided into five groups (15 in each group). A single intraperitoneal (ip) injection of 200 mg/kg streptozotocin (STZ) was administered to the mice to induce diabetes. The control group received normal saline, and the diabetic groups received normal saline or 50, 250 and 500 mg/kg of RC extract for 28 days...

Objective: To determine how pre-stroke cognitive impairment can be detected, its mechanism, and influence on outcome and management. Methods: Literature search. Results: (i) A systematic approach with the Informant Questionnaire of Cognitive Decline in the Elderly is recommended; (ii) Pre-stroke cognitive impairment may be due to brain lesions of vascular, degenerative, or mixed origin; (iii) Patients with pre-stroke dementia, have worse outcomes, more seizures, delirium, and depression, and higher mortality rates; they often need to be institutionalised after their stroke; (iv) Although the safety profile of treatment is not as good as that of cognitively normal patients, the risk:benefit ratio is in favour of treating these patients like others...

Doxorubicin (DOX) is an effective chemotherapeutic drug in the treatment of various types of cancers. However, its clinical application has been largely limited by potential development of cardiotoxicity. Previously we have shown that ultra-violet radiation resistance-associated gene (UVRAG), an autophagy-related protein, is essential for the maintenance of autophagic flux in the heart under physiological conditions. Here, we sought to determine the role of UVRAG-mediated autophagy in DOX-induced cardiotoxicity...

Ethanol is an important risk factor for the occurrence of several brain disorders that depend on the amount, period and frequency of its consumption. Chronic use of ethanol often leads to the development of neurodegenerative syndromes, which cause morphological and functional impairments such as foetal alcohol syndrome in newborns exposed to ethanol during pregnancy, Wernicke-Korsakoff Syndrome and, more rarely, Marchiafava-Bignami disease (MBD). MBD is characterized by primary degeneration of the corpus callosum, without inflammation and is associated with oxidative stress and hypovitaminosis, as well as altered mental status, to mention dementia, seizures, depression and so on...

Major depressive disorder (MDD) is a neuropsychiatric disease that is associated with profound disturbances in affected individuals. Elucidating the pathophysiology of MDD has been frustratingly slow, especially concerning the neurochemical events and brain regions associated with disease progression. Thus, we evaluated the time-course (up to 8weeks) behavioral and biochemical effects in mice that underwent to a bilateral olfactory bulbectomy (OBX), which is used to modeling depressive-like behavior in rodents...
