OBJECTIVE: Mal de debarquement syndrome (MdDS) is a balance disorder that typically starts after an extended exposure to passive motion, such as a boat or plane ride. Management is typically supportive (e.g. physical therapy), and symptoms that persist beyond 6 months have been described as unlikely to remit. This study was conducted to evaluate the response of patients with MdDS to management with migraine prophylaxis, including lifestyle changes and medical therapy. STUDY DESIGN: Prospective review...

Approximately one-third of patients with major depressive disorders (MDDs) are resistant to current treatment methods, and the majority of cases relapse at some point during therapy. This has resulted in novel treatments being adopted, including subanesthetic doses of ketamine, which affects aberrant neuroplastic circuits, glutamatergic signaling, and the production of brain-derived neurotrophic factor. Ketamine rapidly relieves depressive symptoms in treatment-resistant major depressive disorder patients with effects that last for up to 2 weeks even after a single administration...

Mal de débarquement syndrome (MdDS) is typified by a prolonged rocking sensation - for a month or longer - that begins immediately following a lengthy exposure to motion. The provoking motion is usually a sea voyage. About 80% of MdDS sufferers are women, and most of them are middle-aged. MdDS patients are troubled by more migraine headaches than controls. Unlike dizziness caused by vestibular disorders or motion sickness, the symptoms of MdDS usually improve with re-exposure to motion. The long duration of symptoms - a month or more - distinguishes MdDS from land-sickness...

Major depressive disorders (MDDs) are a widespread and burdensome mental illness associated with a high comorbidity with other conditions and a significantly reduced life expectancy compared to the general population. Therefore, targeted actions are needed to improve physical health in people with MDDs, in addition to ongoing efforts to enhance psychological well-being. Meanwhile, the positive effects of exercise training on the treatment of MDDs are well documented, while compelling evidence exists that exercise interventions can improve cardiorespiratory fitness in clinically meaningful ways...

In case of incidental confinement failure, mixed oxide (MOX) fuel preparation may expose workers to plutonium aerosols. Due to its potential toxicity, occupational exposure to plutonium compounds should be kept as low as reasonably achievable. To ensure the absence of significant intake of radionuclides, workers at risk of internal contamination are monitored by periodic bioassay planned in a routine monitoring programme. From bioassay results, internal dose may be estimated. However, accurate dose calculation relies on known exposure conditions, which are rarely available when the exposure is demonstrated by routine monitoring only...

BACKGROUND: Technological advances enable the cost-effective acquisition of Multi-Modal Data Sets (MMDS) composed of measurements for multiple, high-dimensional data types obtained from a common set of bio-samples. The joint analysis of the data matrices associated with the different data types of a MMDS should provide a more focused view of the biology underlying complex diseases such as cancer that would not be apparent from the analysis of a single data type alone. As multi-modal data rapidly accumulate in research laboratories and public databases such as The Cancer Genome Atlas (TCGA), the translation of such data into clinically actionable knowledge has been slowed by the lack of computational tools capable of analyzing MMDSs...

Structural imaging studies investigating the relationship between hippocampal volume (HCV) and peripheral measures of glucocorticoids (GCs) have produced conflicting results in both normal populations and in individuals with MDD, raising the possibility of other modulating factors. In preclinical studies, dehydroepiandrosterone (DHEA) and its sulfate ester (DHEAS; together abbreviated, DHEA(S)) have been shown to antagonize the actions of GCs on the central nervous system. Therefore, considering the relationship of HCV to both of these hormones simultaneously may be important, although it has rarely been done in human populations...

BACKGROUND AND OBJECTIVE: Multidisciplinary discussions (MDDs) have been shown to improve diagnostic accuracy in interstitial lung disease (ILD) diagnosis. However, their clinical impact on patient care has never been clearly demonstrated. We describe the effect that an ILD multidisciplinary service has upon the diagnosis and management of patients with suspected ILD. METHODS: Patients at two specialized centres with suspected ILD underwent ILD multidisciplinary team review (ILD-MDT) (standard ILD clinic visit and diagnostic review at ILD-MDD)...

BACKGROUND: Sleep disturbances are a common co-occurring disturbance in patients with major depressive disorders (MDDs) and accordingly deserve particular attention. Using a randomized design, we investigated the effects of three different adjuvant interventions on sleep and depression among patients with MDD: a sleep hygiene program (SHP), lorazepam (LOR), and their combination (SHP-LOR). METHODS: A total of 120 outpatients with diagnosed MDD (mean age: 48.25 years; 56...

Previously, we proposed that the mean diffusivity (MD), a measure of diffusion tensor imaging (DTI) in areas of the dopaminergic system (MDDS), is associated with motivation. In this study, we tested if and how the motivational state is associated with MD in comparison with other mood states. We also tested the associations of these mood states with multiple cognitive functions. We examined these issues in 766 right-handed healthy young adults. We employed analyses of MD and a psychological measure of the profile of mood states (POMS) as well as multiple cognitive functions...

Difficulty regulating emotions following stressful events is a hallmark of Major Depressive Disorder (MDD). Although individuals' ability to regulate their emotions is believed to have direct consequences for both emotional and physical wellbeing, few studies have examined the cardiovascular effects of different emotion regulation strategies in MDD. To the best of our knowledge, the current study is the first to examine the effects of two emotion regulation strategies, cognitive distraction and rumination, on both self-reported sadness and respiratory sinus arrhythmia (RSA) in individuals with MDD and healthy controls (CTLs)...

OBJECTIVE: Previous studies indicate that emotion regulation problems in major depressive disorder (MDD) may be caused by difficulties in preferring useful emotions according to their goals. We investigated expected emotional usefulness and emotional preference in individuals with MDD (MDDs) and healthy controls (HCs). METHODS: Participants were given an interpersonal scenario with two different goals (confrontation and collaboration) and rated their willingness to participate in emotion-provoking activities and the expected usefulness of a particular emotion...

BACKGROUND: Mal de debarquement syndrome is a medically refractory disorder characterized by chronic rocking dizziness that occurs after exposure to passive motion. Repetitive transcranial magnetic stimulation (rTMS) can acutely suppress the rocking dizziness but treatment options that extend the benefit of rTMS are needed. OBJECTIVES: 1) To determine whether transcranial direct current stimulation (tDCS) added after rTMS can extend the benefit of rTMS; 2) to determine whether participants can safely perform tDCS at home...

Lactose permease of E. coli (LacY) is a secondary active transporter (SAT) that belongs to the major facilitator superfamily (MFS). Experimental structures of the cytoplasmic-open and more recently occluded-like structure have been determined, however, the crystal structure of LacY in the periplasmic-open state is still not available. The periplasmic-open LacY structure is important for understanding complete proton/sugar transport process of LacY as well as other similar SAT proteins. Previously, a structural model of periplasmic-open LacY has been obtained through a two-step hybrid implicit-explicit (IM-EX) simulation method (JMB404: 506)...

Serum levels of brain-derived neurotrophic factor (BDNF) are low in major depressive disorder (MDD), and were recently shown to decrease in chronic depression, but whether this is a trait or state marker of MDD remains unclear. We investigated whether serum BDNF levels decrease before or after the developments of MDD and other mood disorders through a case-control study nested in a cohort of 1276 women aged 75-84 years in 2008. Psychiatrists using the Structured Clinical Interview for DSM-IV identified incident cases of mood disorders at follow-up surveys in 2010 and 2012: 28 of MDDs, 39 of minor depressive disorders (minDDs) and 8 of minor depressive episodes with a history of major depressive episodes (minDEs with MDE history)...

BACKGROUND: Alexithymia has been frequently associated with major depression disorders (MDD). Yet little is known about the exact relationship of alexithymia and MDD. In order to explore this subject matter, the neural connectivity associated with alexithymia in people with MDD and matched nonclinical controls were compared. METHODS: Twenty-two females diagnosed with first-episode MDD and twenty-one matched nonclinical controls were MRI brain-scanned with diffusion-tensor-imaging and resting-state-functional-imaging methods, and self-reported the Chinese 20-item Toronto Alexithymia Scale...

UNLABELLED: Numerous clinical reports underscore the frequency of olfactory impairments in patients suffering from major depressive disorders (MDDs), yet the underlying physiopathological mechanisms remain poorly understood. We hypothesized that one key link between olfactory deficits and MDD lies in hypercortisolemia, a cardinal symptom of MDD. Corticosterone (CORT) is known to negatively correlate with hippocampal neurogenesis, yet its effects on olfactory neurogenesis and olfaction remain unknown...

Mal de debarquement (MdD) is a subjective perception of self-motion after exposure to passive motion, in most cases sea travel, hence the name. Mal de debarquement occurs quite frequently in otherwise healthy individuals for a short period of time (several hours). However, in some people symptoms remain for a longer period of time or even persist and this is then called mal de debarquement syndrome (MdDS). The underlying pathogenesis is poorly understood and therefore, treatment options are limited. In general, limited studies have focused on the topic, but the past few years more and more interest has been attributed to MdDS and its facets, which is reflected by an increasing number of papers...

Brexpiprazole (Rexulti®) is an atypical antipsychotic that has been developed by Otsuka Pharmaceutical Co. Ltd and H. Lundbeck A/S as an oral treatment for several psychiatric disorders. Brexpiprazole is a novel serotonin-dopamine activity modulator that acts as a partial agonist of serotonin 1A (5-HT1A) and dopamine D2 receptors, as well as a potent antagonist of 5-HT2A receptors and noradrenergic α1B and α2C receptors. In July 2015, brexpiprazole received its first approval in the USA for use as an adjunctive treatment of major depressive disorder (MDD) and the treatment of schizophrenia...
