The aim of this systematic review and meta-analysis was to provide a comprehensive evaluation of the role of emotion (dys)regulation in gambling disorder (GD). GS-441524 chemical structure PsycINFO, PsycARTICLES, MEDLINE, Scopus, Web of Science, and PubMed were systematically searched for articles published until November 3, 2020. Forty-nine studies were considered for the systematic review; of these, 38 comprising 5242 participants met the inclusion criteria for the meta-analysis. Associations were found between GD and specific emotion regulation (ER) deficits, namely (1) nonacceptance of negative emotional states, (2) difficulties in maintaining goal-directed behaviors when faced with intense emotional contexts, (3) lack of clarity about emotional states (poor emotional awareness), (4) low impulse control in reaction to negative emotional states, and (5) difficulties in accessing adaptive ER strategies. We furthermore found that GD is associated with a tendency for emotional suppression, which is known as a maladaptive ER strategy and linked with reduced mindfulness abilities. Additional moderator analyses were conducted regarding age, gender, type of instrument used to measure GD, clinical status of the samples, and quality of the studies. Overall, the data demonstrated consistent and significant associations between GD and ER. This systematic review and meta-analysis mostly supports the conceptualization of GD as an addictive disorder characterized by ER deficits and stresses the need to develop interventions in ER deficits that are tailored to the specificities of GD.Figure-ground, that is the segmentation of visual information into objects and their surrounding backgrounds, provides structure for visual attention. Recent evidence shows a novel role of vergence eye movements in visual attention. In the present work, vergence responses during figure-ground segregation tasks are psychophysically investigated. We show that during a figure-ground detection task, subjects convergence their eyes. Vergence eye movements are larger in figure trials than in ground trials. In detected figures trials, vergence are stronger than in trials where the figure went unnoticed. Moreover in figure trials, vergence responses are stronger to low-contrast figures than to high-contrast figures. We argue that these discriminative vergence responses have a role in figure-ground.Although dispositional shame and guilt have been distinguished by perceptions of the self and behavioral responses, the underlying information processing patterns remain unclear. We hypothesized that an ability to contemplate alternatives to perceptions of the current environment, i.e., flexibility in perspective shifting, may be essential to both dispositions. Dispositional shame may additionally relate to negative relational knowledge that involves a self-representation of being rejected. One hundred and six community participants rated the two dispositions, and had their flexibility in perspective shifting and internalized self-association with rejection assessed. Regression analysis indicated that a lower cost of perspective shifting was observed with dispositional guilt and shame. Yet, unlike a direct association with perspective shifting for dispositional guilt, it was an interaction between perspective shifting and negative relational knowledge that accounted for dispositional shame. The association of dispositional shame with perspective shifting was contingent upon the tendency to pair the self with rejection.Tip-of-the-tongue states (TOTs) are feelings of impending word retrieval success during a current failure to retrieve a target word. Though much is known and understood about TOT states from decades of research, research on potential psychophysiological correlates of the TOT state is still in its infancy, and existing studies point toward the involvement of neural processes that are associated with enhanced attention, motivation, and information-seeking. In the present study, we demonstrate that, during instances of target retrieval failure, TOT states are associated with greater pupillary dilation (i.e., autonomic arousal) in 91% of our sample. This is the first study to demonstrate a pupillometric correlate of the TOT experience, and this finding provides an important step toward understanding emotional attributes associated with TOT states. Mean pupil dilation also increased such that instances of target identification failure that were unaccompanied by TOT states less then instances in which TOTs occurred less then instances of target identification success. It is possible that TOTs reflect an intermediary state between complete target retrieval failure and full target retrieval.The short-term memory binding (STMB) test involves the ability to hold in memory the integration between surface features, such as shapes and colours. The STMB test has been used to detect Alzheimer's disease (AD) at different stages, from preclinical to dementia, showing promising results. The objective of the present study was to verify whether the STMB test could differentiate patients with distinct biomarker profiles in the AD continuum. The sample comprised 18 cognitively unimpaired (CU) participants, 30 mild cognitive impairment (MCI) and 23 AD patients. All participants underwent positron emission tomography (PET) with Pittsburgh compound-B labelled with carbon-11 ([11C]PIB) assessing amyloid beta (Aβ) aggregation (A) and 18fluorine-fluorodeoxyglucose ([18F]FDG)-PET assessing neurodegeneration (N) (A-N- [n = 35]); A+N- [n = 11]; A+ N+ [n = 19]). Participants who were negative and positive for amyloid deposition were compared in the absence (A-N- vs. A+N-) of neurodegeneration. When compared with the RAVLT and SKT memory tests, the STMB was the only cognitive task that differentiated these groups, predicting the group outcome in logistic regression analyses. The STMB test showed to be sensitive to the signs of AD pathology and may represent a cognitive marker within the AD continuum.
This study compares the safety and efficacy of a fixed dose of 4-factor prothrombin complex concentrate (4FPCC) to the FDA-approved variable dosing for reversal of warfarin-induced anticoagulation.

This was a single-center, prospective, open-label, randomized controlled trial with subjects randomized to 4FPCC at a fixed dose of 1500 IU or the FDA-approved variable dosing regimen. The primary efficacy outcome (reversal success) was defined as a post-intervention international normalized ratio (INR) of less than or equal to 1.5. Given that 4FPCC is the standard of care for reversal of warfarin-induced anticoagulation an active-controlled approach was employed with the two dosing regimens compared based on efficacy, cost, and safety outcomes.

71 subjects (34 in the fixed dose group and 37 in the variable dose group) completed the study. There were no significant differences in age, gender, weight, initial INR, or indication for 4FPCC administration between the two treatment groups. Reversal success in the fixed-dose group was 61.8%, while in the variable dose group reversal success was 89.2%. Reversal success in the fixed-dose group was significantly lower than the rate of reversal success in the variable dose group (27.4% lower, p = 0.011).

The results of this study provide evidence that fixed dosing results in lower reversal success rates as compared to variable dosing of 4FPCC for warfarin-induced anticoagulation.

Orbital subperiosteal hematoma is a rare ED diagnosis that is typically associated with trauma, though can infrequently occur spontaneously in the setting of sudden elevations in cranial venous pressure, bleeding diathesis, and sinusitis. We present a case of a 55-year-old female with a history of chronic sinusitis who presented to the ED with a three-day history of left-sided periorbital swelling along with painful extraocular movements and markedly decreased visual acuity following a cross-country road trip through elevation. Contrast computed tomography scan of the orbits revealed a large extraconal collection in the subperiosteal space causing significant mass effect on the left globe, along with findings of diffuse sinonasal disease bilaterally. Intravenous antibiotics were started immediately and the patient underwent surgical incision and drainage of the subperiosteal space, where she was diagnosed with a spontaneous subperiosteal orbital hematoma secondary to chronic sinusitis. Within the literature, there are fewer than 20 case reports of orbital subperiosteal hematoma secondary to sinusitis. The purpose of this case report is to assist emergency physicians in considering the rare but potentially vision-threatening condition of spontaneous subperiosteal orbital hematoma within their differential diagnosis of patients with periorbital swelling and proptosis, as well as to provide an approach to management within the ED.Burning Hands Syndrome is an unusual variant of central cord syndrome. There have been few published reports, and none in the emergency medicine literature. We present a case of Burning Hands Syndrome in which there were no computed tomography (CT) findings of cervical spine injury and only subtle magnetic resonance (MR) abnormalities. We discuss the importance of early diagnosis, as the optimal management of these patients ultimately depends upon prompt recognition of the underlying cervical trauma and a spinal cord at risk for further injury.
The COVID-19 pandemic has forced health care workers to explore alternative personal protective equipment (PPE) strategies due to traditional product shortages in the setting of increased global demand. Some physicians have chosen to use elastomeric face masks (EFMs), traditionally used in non-healthcare industries.

We performed a prospective cohort study of Emergency Medicine (EM) physicians working at a Level 1 Trauma Center who chose to use self-supplied EFMs for PPE. All subjects used commercial EFMs with disposable filters (N95, P95, or P100). All subjects chose their mask size independently with no input from employee health regarding appropriate fit. Per study protocol, subjects were fit tested periodically during clinical shifts over the course of the 6-week study period. All investigators performing fit testing underwent OSHA qualitative fit testing training. Data collected included mask/filters age, subjective assessment of mask seal quality, and fit test results. The data were analyzed using descriptive statistics.

105 fit tests were performed on physicians wearing EFMs over the course of 49 shifts. Physicians felt their fit was adequate for all tests performed. There were no fit test failures in any subjects.

EFMs have an extremely low failure rate. Physicians are able to assess the adequacy of fit and accurately choose EFM size.
