Vigilance refers to the brain alertness to objective things, including the concentration of attention and the capability to response emergencies. It is of great importance to study vigilance monitoring to avoid accidents caused by decrease of vigilance. In this study, traditional Mackworth Clock Test (MCT) was modified to induce decline of attended and unattended vigilance. We analyzed EEG features in different levels of attended vigilance and assessed unattended vigilance by amplitude of mismatch negative (MMN) which can be evoked by audio odd ball stimulations...

Opipramol was developed in the 1960s as an antidepressant and has chemical similarities with tricyclic antidepressants. Pharmacodynamic properties with absent reuptake inhibition of serotonin and noradrenaline and agonism at sigma receptors distinguish opipramol from tricyclics. Furthermore, antidepressive effects are smaller than the anxiolytic ones. The mechanism of action of opipramol is currently not sufficiently understood. Agonistic effects at sigma receptors have been linked with therapeutic effects...

PURPOSE: The aim of this study was to explore the treatment, patient, and impairment-related risk factors associated with upper limb dysfunctions in breast cancer survivors. METHODS: A cross-sectional study was performed in 274 women treated for breast cancer. The following risk factors were analysed by bivariable and multivariable analysis: 1) treatment-related variables (type of surgery, levels of lymph node dissected, radiotherapy, chemotherapy, hormone therapy and trastuzumab); 2) patient's related variables (age and Body Mass Index); 3) and finally impairment-related variables such as pain (intensity, quality and pressure hypersensitivity, signs of central sensitisation, the degree of pain catastrophizing and vigilance and awareness to pain), active ROM and upper limb strength were investigated...

Importance: In the United States, hospitals receive accreditation through unannounced on-site inspections (ie, surveys) by The Joint Commission (TJC), which are high-pressure periods to demonstrate compliance with best practices. No research has addressed whether the potential changes in behavior and heightened vigilance during a TJC survey are associated with changes in patient outcomes. Objective: To assess whether heightened vigilance during survey weeks is associated with improved patient outcomes compared with nonsurvey weeks, particularly in major teaching hospitals...

Treatment regimen fatigue (TRF) is a decreased desire and motivation to maintain vigilance in adhering to treatment, and little is known about TRF in people living with HIV. We aimed to develop a conceptual framework of TRF. Five focus groups were conducted in 2014. Eligible participants were (a) HIV infected, (b) at least 18 years of age, (c) prescribed antiretroviral therapy, and (d) fluent in English. Data were analyzed using thematic analysis. Analyses revealed these themes: patient experiences of TRF; etiological factors at the systems, provider, and patient levels; strategies to manage TRF; consequences of TRF; and protective factors that prevent the occurrence of TRF...

OBJECTIVE: A new active safety concept that engages the driver's psychosensory pain-processing mechanism to automatically trigger vigilance enhancement on-demand was proposed in Chang ( 2012 ). This concept is based on the hypothesis that a human's pain threshold will decline as he/she becomes drowsy, consequently triggering the vigilance enhancer. The objective of this pilot study was to develop methods to test this hypothesis, the results of which could lead to further refinement of the hypothesis and methods, with the ultimate goal of developing new active safety concepts that exploit the driver's endogenous psychosensory pain-processing mechanisms...

Chronic granulomatous disease (CGD) is a primary immunodeficiency with an incidence of 1/200,000-250,000 live births. CGD affects mainly male patients, most of the mutations being X-linked, and autosomal recessive forms occur more frequently in communities with greater numbers of consanguineous marriages. CGD is characterized by sensitivity to recurrent and severe bacterial and fungal infections, with formation of granulomas due to the inability of phagocytes to generate reactive oxygen compounds, necessary for the intracellular death of phagocytic microorganisms...

Ebola virus (EBOV) is an extremely contagious pathogen and causes lethal hemorrhagic fever disease in man and animals with high fatality rates. The recently occurred Ebola virus disease (EVD) outbreaks in the West African countries have categorized it as an international health concern. For the virus maintenance and transmission, the non-human primates and reservoir hosts like fruit bats have played a vital role. Furthermore, the virus may also get transferred through contaminated biological fluids like breast milk, tears, urine, semen, blood, etc...

Disturbed sleep and altered sleep homeostasis are core features of many psychiatric disorders such as depression. Chronic uncontrollable stress is considered an important factor in the development of depression, but little is known on how chronic stress affects sleep regulation and sleep homeostasis. We therefore examined the effects of chronic social stress (CSS) on sleep regulation in mice. Adult male C57BL/6 mice were implanted for electrocortical recordings (ECoG) and underwent either a 10-day CSS protocol or control handling (CON)...

BACKGROUND: International studies show that dementia is often recognized at later stages in general practice. Pure knowledge-sharing interventions could not change this in a sustainable manner. Concepts for changing attitudes of general practitioners (GPs) are required. OBJECTIVES: What barriers affect GPs' recognition of and diagnostic approach to dementia? What recommendations for a GP-specific diagnostic procedure can be derived from this? METHODS: Metasynthesis of qualitative studies with GPs on barriers to dementia recognition, explication of the "frailty" concept and the diagnostic approach described therein and the development of an approach in cases of suspected cognitive decline in a multiprofessional team...

The Amyloid Precursor Protein (App) plays a crucial role in Alzheimer disease (AD) via the production and deposition of toxic β-amyloid peptides. App is heavily expressed in neurons where the vast majority of studies investigating its function have been carried out, while almost nothing is known about its function in glia, where it is also expressed, and can potentially participate in the regulation of neuronal physiology. In this report, we investigated whether Appl, the Drosophila homolog of App, could influence sleep-wake regulation when its function is manipulated in glial cells...

INTRODUCTION: Hereditary hemorrhagic telangiectasia (HHT) is characterized by frequent severe bleeding, particularly epistaxis, and life-threatening complications including stroke, brain abscess and heart failure. The psychological impact of HHT is not known. We conducted this cross sectional study to determine the prevalence of depression and post-traumatic stress disorder (PTSD) related to HHT. METHODS: A survey tool comprising demographic and clinical information and two validated self-administered questionnaires, the PTSD checklist for DSM-5 (PCL-5) and Beck Depression Inventory-II (BDI-II), was distributed to individuals with HHT...

R Rauber, M B Manser
Sentinel behaviour, a form of coordinated vigilance, occurs in a limited range of species, mostly in cooperative breeders. In some species sentinels confirm their presence vocally by giving a single sentinel call type, whereby the rate and subtle acoustic changes provide graded information on the variation of perceived predation risk. In contrast, meerkat (Suricata suricatta) sentinels produce six different sentinel call types. Here we show that manipulation of perception of danger has different effects on the likelihood of emitting these different call types, and that these call types affect foraging individuals differently...

Vigilance is the ability of an observer to maintain attention for extended periods of time; however, performance tends to decline with time on watch, a pattern referred to as the vigilance decrement. Previous research has focused on factors that attenuate the decrement; however, one factor rarely studied is the effect of social facilitation. The purpose for the present investigation was to determine how different types of social presence affected the performance, workload, and stress of vigilance. It was hypothesized that the presence of a supervisory figure would increase overall performance, but may occur at the cost of increased workload and stress...

Surgical emphysema secondary to tracheal tear is a rare but serious complication after thyroidectomy. It is usually resolved by conservative management; but in case of compromised airway, early airway control and surgical intervention is required. This is the case report of a 52-year woman diagnosed as thyroid carcinoma, who developed rapidly progressive surgical emphysema involving head and upper thorax, following total thyroidectomy, in post anesthesia care unit (PACU). The complication was related to tracheal tear occurring during excision of huge thyroid mass, encroaching trachea...

BACKGROUND: Clinical decision support (CDS) in e-prescribing can improve safety by alerting potential errors, but introduces new sources of risk. Automation bias (AB) occurs when users over-rely on CDS, reducing vigilance in information seeking and processing. Evidence of AB has been found in other clinical tasks, but has not yet been tested with e-prescribing. This study tests for the presence of AB in e-prescribing and the impact of task complexity and interruptions on AB. METHODS: One hundred and twenty students in the final two years of a medical degree prescribed medicines for nine clinical scenarios using a simulated e-prescribing system...

The effect of sleep deprivation on pain sensitivity has typically been studied using total and partial sleep deprivation protocols. These protocols do not mimic the fragmented pattern of sleep disruption usually observed in individuals with clinical pain conditions. Therefore, we conducted a controlled-experiment to investigate the effect of sleep fragmentation on pain perception (deep pain: forearm muscle ischaemia, and superficial pain: graded pin-pricks applied to the skin) in 11 healthy young women following two consecutive nights of sleep fragmentation, compared with a normal night of sleep...

We evaluated whether sliding-window analysis can reveal functionally relevant brain network dynamics during a well-established fear conditioning paradigm. To this end, we tested if fMRI fluctuations in amygdala functional connectivity (FC) can be related to task-induced changes in physiological arousal and vigilance, as reflected in the skin conductance level (SCL). Thirty-two healthy individuals participated in the study. For the sliding-window analysis we used windows that were shifted by one volume at a time...
