Sustained response to symmetry in extrastriate areas after stimulus offset: An EEG study.

Electrophysiological (EEG) studies of human perception have found that amplitude at posterior electrodes is more negative for symmetrical patterns compared to asymmetrical patterns. This negativity lasts for hundreds of milliseconds and it has been called sustained posterior negativity (SPN). Symmetry activates a network of visual areas, including the lateral occipital complex (LOC).

Expecting the worst: Investigating the effects of trigger warnings on reactions to ambiguously themed photos.

Trigger warnings are messages alerting people to content containing themes that could cause distressing emotional reactions. Advocates claim that warnings allow people to prepare themselves and subsequently reduce negative reactions toward content, while critics insist warnings may increase negative interpretations. Here, we investigated (a) the emotional impact of viewing a warning message, (b) if a warning message would increase or decrease participants' negative evaluations of a set of ambiguous photos, and (c) how participants evaluated overall study participation.

Visual and auditory contextual cues differentially influence alcohol-related inhibitory control.

Representing a more immersive testing environment, the current study exposed individuals to both alcohol-related visual and auditory cues to assess their respective impact on alcohol-related inhibitory control. It examined further whether individual variation in alcohol consumption and trait effortful control may predict inhibitory control performance. Twenty-five U.

Imagining trauma: Memory amplification and the role of elaborative cognitions.

Background And Objectives: Trauma victims, such as war veterans, often remember additional traumatic events over time: the "memory amplification effect". This effect is associated with the re-experiencing symptoms of post-traumatic stress disorder (PTSD), including frequent and intrusive images of the trauma. One explanation for memory amplification is that people gradually incorporate new, imagined information about the trauma with what they actually experienced, leading to an amplified memory for what actually happened.

Use of Focused Assessment with Sonography in Trauma Examination Skills in the Evaluation of Non-trauma Patients.

Study objectives Although the focused assessment with sonography in trauma (FAST) examination was initially developed for rapid evaluation of trauma patients, the basic skillset required to perform a FAST examination provides valuable information that may alter a non-trauma patient's clinical course. The objective of this study was to determine the utility of the FAST examination in the emergency department management of non-trauma patients. Methods Cases in which the FAST examination was used to direct care in non-trauma patients were retrospectively reviewed.

Incidence of and Risk Factors for Skin Cancer in Organ Transplant Recipients in the United States.

Importance: Skin cancer is the most common malignancy occurring after organ transplantation. Although previous research has reported an increased risk of skin cancer in solid organ transplant recipients (OTRs), no study has estimated the posttransplant population-based incidence in the United States.

Objective: To determine the incidence and evaluate the risk factors for posttransplant skin cancer, including squamous cell carcinoma (SCC), melanoma (MM), and Merkel cell carcinoma (MCC) in a cohort of US OTRs receiving a primary organ transplant in 2003 or 2008.

Memory amplification for trauma: Investigating the role of analogue PTSD symptoms in the laboratory.

Victims of trauma often remember their experience as being more traumatic later, compared to immediately after, the event took place. This finding-the "memory amplification effect"-is associated with increased re-experiencing symptoms. However, the effect has been found almost exclusively in field-based studies.

Advance directives for older adults in the emergency department: a systematic review.

Background: It has been more than two decades since the passage of the Patient Self-Determination Act (PSDA) of 1991, an act that requires many medical points of care, including emergency departments (EDs), to provide information to patients about advance directives (ADs).

Objective: The study objective was to determine the prevalence of ADs among ED patients with a focus on older adults and factors associated with rates of completion.

Methods: We searched PubMed, Embase, PsycINFO, CINAHL, Web of Science, Medline, and the Cochrane Library.

The global nursing shortage: an overview of issues and actions.

Today's global nursing shortage is having an adverse impact on health systems around the world. A major initiative by the International Council of Nurses (ICN) yielded important information regarding the shortage and solutions to it. These are organized into five priority areas: policy intervention; macroeconomics and health sector funding; workforce planning and policy, including regulation; positive practice environments; and retention and recruitment (includes migration); and nursing leadership.
