Background: Reflex molecular testing, the process of profiling specimens at diagnosis, is emerging in oncology, allowing for prompt therapy initiation, and potentially improving outcomes. This study evaluates the impact of reflex BRAF testing on treatment timelines and outcomes in melanoma, lung and colorectal cancers at the McGill University Health Center (MUHC).
Methods: A retrospective chart review was conducted at the MUHC.
Introduction: A greater sense of purpose in life is associated with several health benefits relevant for active aging, but the mechanisms remain unclear. We evaluated if purpose in life was associated with indices of brain health.
Methods: We examined data from the Midlife in the United States (MIDUS) Neuroscience Project.
Background: Patient dignity is a core component of medicine and health care, yet maintaining patient dignity can be challenging in clinical settings in dermatology, specifically during a total body skin examinations (TBSE) for appropriate assessment and diagnosis. A recent study evaluated patient perspectives in dermatology. The purpose of this study was to investigate current draping practices and perspectives from a physicians' perspective.

Drug-induced bullous pemphigoid is a rare but potentially serious immune-related adverse event that should be considered in patients with advanced malignancies undergoing immunotherapy, with immune checkpoint inhibitors emerging in particular as a well-documented drug association in drug-induced bullous pemphigoid. We present a 74-year-old female with recurrent metastatic programmed cell death-ligand 1-positive squamous cell carcinoma of the head and neck area who developed drug-induced bullous pemphigoid in the setting of immunotherapy with a novel immunoglobulin-like transcript 4 inhibitor (MK-4830) in combination with pembrolizumab.

Our primary safety outcome was number, and grade of adverse events. Our primary efficacy outcome was clinical responses.

Nonetheless, AMR surveillance remains scarce in sub-Saharan Africa, where BSI treatment is largely empirical. The aim of the study was to determine the distribution and AMR patterns of BSI-causing NTS, , and other Gram-negative bacteria in Ghana.

As standardized TBSE draping practices have not been investigated in a dermatology setting, we sought out to investigate subjective patient experiences of draping practices.
Methods: A cross-sectional study was performed using a paper survey in dermatology hospital clinics over a 6-month period to 150 patients.
Background: Individual differences in stress appraisals influence trajectories of risk and resilience following exposure to chronic and acute stressors. Smaller hippocampal volume may contribute to elevated stress appraisals via deficient pattern separation, a process depending on dentate gyrus (DG)/CA3 hippocampal subfields. Here, we investigated links between perceived stress, DG/CA3 volume, and behavioral pattern separation to test hypothesized mechanisms underlying stress-related psychopathology.

The amygdala is likely to play an important role, given its sensitivity to threat and connectivity with descending immune modulatory pathways. In this study, we recruited thirty asthmatic participants and examined glucose metabolism in the amygdala, using [F-18]fluorodeoxyglucose positron emission tomography, during a laboratory stressor.

The uncinate fasciculus is a white matter tract that may facilitate emotion regulation by carrying connections from the prefrontal cortex to regions of the temporal lobe, including the amygdala. Depression and anxiety are associated with reduced uncinate fasciculus fractional anisotropy (FA)-a diffusion tensor imaging measure related to white matter integrity. In the current study, we tested whether FA in the uncinate fasciculus is associated with individual differences in emotional recovery measured with corrugator supercilii electromyography in response to negative, neutral, and positive images in 108 participants from the Midlife in the US (MIDUS; http://midus.

Calcium gluconate is a commonly used medication to prevent cardiac arrhythmias in the setting of hyperkalemia and cardiac arrest during resuscitation and life support. Extravasation of calcium gluconate may result in skin necrosis and a bullous reaction in its most severe form, which should be promptly recognized so that treatment can be provided.

This approach shows promise for treating hematologic cancers in early phase clinical trials, but overall safety and efficacy remain poorly described. We conducted a systematic review assessing the use of autologous cell vaccination in treating hematologic cancers.

The COVID-19 pandemic has incited research aimed at developing a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine. As SARS-CoV-2 vaccines are developed and made available, the assessment of anticipated safety and efficacy in patients with immune-mediated dermatologic diseases and requiring immunosuppressive and/or immunomodulatory therapy is particularly important.
View Article and Find Full Text PDFThe bed nucleus of the stria terminalis (BNST) and central nucleus of the amygdala (CeA) are hypothesized to be the output nodes of the extended amygdala threat response, integrating multiple signals to coordinate the threat response via outputs to the hypothalamus and brainstem. The BNST and CeA are structurally and functionally connected, suggesting interactions between these regions may regulate how the response to provocation unfolds. However, the relationship between human BNST-CeA connectivity and the behavioral response to affective stimuli is little understood.

Translating the results of these studies to inform prevention, detection, and response efforts often can be challenging, especially if prior relationships and communications have not been established with decision-makers. Whatever scientific information is shared with decision-makers before, during, and after public health emergencies is highly dependent on the individuals or organizations who are communicating with policy-makers.

Cognitive reserve (CR) theory postulates that individuals with higher levels of intellectual enrichment can tolerate more pathology than others before exhibiting cognitive impairment.

Detailed studies are often limited to characterizing how one or a few genes contributed to a trait's emergence, and thus our knowledge of how entire GRNs evolve their coordinated expression of each gene remains unresolved.

Emotional processing often continues beyond the presentation of emotionally evocative stimuli, which can result in affective biasing or coloring of subsequently encountered events. Here, we describe neural correlates of affective coloring and examine how individual differences in affective style impact the magnitude of affective coloring. We conducted functional magnetic resonance imaging in 117 adults who passively viewed negative, neutral and positive pictures presented 2 s prior to neutral faces.

Physical activity is commonly assessed using self-reported questionnaires, which are limited by recall and response biases. Recent advancements in wearable technology have provided oncologists with new opportunities to obtain real-time, objective physical activity data.
