Trauma care is complex. Acute and critical care clinicians perceive trauma as a skilled response to critical injury or accident that occurs to patients, but trauma exists on many levels. One of those is a grim reality for patients who are lesbian, gay, bisexual, transgender, queer or questioning, and from other sexual and gender minorities (LGBTQ+). A lifetime of trauma through stigma, discrimination, and victimization is too often present. Owing to distrust of the health care system and clinicians, LGBTQ+ experience health and health care disparities...

SIGNIFICANCE: Neuromodulation devices are rapidly evolving for the treatment of neurological diseases and conditions. Injury from implantation or long-term use without obvious functional losses is often only detectable through terminal histology. New technologies are needed that assess the peripheral nervous system (PNS) under normal and diseased or injured conditions. AIM: We aim to demonstrate an imaging and stimulation platform that can elucidate the biological mechanisms and impacts of neurostimulation in the PNS and apply it to the sciatic nerve to extract imaging metrics indicating electrical overstimulation...

OBJECTIVE: Evidence shows that Black individuals have higher rates of coercive emergency psychiatric interventions than other racialized groups, yet no studies have elevated the voices of Black patients undergoing emergency psychiatric evaluation. This qualitative study sought to explore the experiences of Black individuals who had been evaluated in a locked psychiatric emergency unit (PEU). METHODS: Electronic health records were used to identify and recruit adult patients (ages ≥18 years) who self-identified as Black and who had undergone evaluation in a locked PEU at a large academic medical center...

Sleep problems are common among veterans with post-traumatic stress disorder and closely associated with hyperarousal symptoms. Transcutaneous vagus nerve stimulation (tVNS) may have potential to improve sleep quality in veterans with PTSD through effects on brain systems relevant to hyperarousal and sleep-wake regulation. The current pilot study examines the effect of 1 h of tVNS administered at "lights out" on sleep architecture, microstructure, and autonomic activity. Thirteen veterans with PTSD completed two nights of laboratory-based polysomnography during which they received 1 h of either active tVNS (tragus) or sham stimulation (earlobe) at "lights out" with randomised order...

Cardiac arrest (CA) is associated with a low rate of survival with favourable neurologic recovery. The most common mechanism of death after successful resuscitation from CA is withdrawal of life-sustaining measures on the basis of perceived poor neurologic prognosis due to underlying hypoxic-ischemic brain injury. Neuroprognostication is an important component of the care pathway for CA patients admitted to hospital but is complex, challenging, and often guided by limited evidence. Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system to evaluate the evidence underlying factors or diagnostic modalities available to determine prognosis, recommendations were generated in the following domains: (1) circumstances immediately after CA; (2) focused neurologic exam; (3) myoclonus and seizures; (4) serum biomarkers; (5) neuroimaging; (6) neurophysiologic testing; and (7) multimodal neuroprognostication...

BACKGROUND: Classically, the torcular Herophili is described as the symmetric junction between the superior sagittal sinus (SSS), transverse sinuses (TSs), and straight sinus (SS). However, finding this pattern in practice is not standard. Anatomical variations are common, and different drainage patterns should be expected. Existing literature proposes highly detailed descriptions and classifications of this region. Still, a simplified and practical categorization is not available. METHODS: We present an anatomical finding of the torcular Herophili discovered on a cadaveric dissection...

A sustainable biomass supply chain would require not only an effective and fluid transportation system with a reduced carbon footprint and costs, but also good soil characteristics ensuring durable biomass feedstock presence. Unlike existing approaches that fail to account for ecological factors, this work integrates ecological as well as economic factors for developing sustainable supply chain development. For feedstock to be sustainably supplied, it necessitates adequate environmental conditions, which need to be captured in supply chain analysis...

Functional MRI (fMRI) data may be contaminated by artifacts arising from a myriad of sources, including subject head motion, respiration, heartbeat, scanner drift, and thermal noise. These artifacts cause deviations from common distributional assumptions, introduce spatial and temporal outliers, and reduce the signal-to-noise ratio of the data-all of which can have negative consequences for the accuracy and power of downstream statistical analysis. Scrubbing is a technique for excluding fMRI volumes thought to be contaminated by artifacts and generally comes in two flavors...

Sclerotinia stem rot (SSR) is a major disease of soybean across the Upper Midwest region of the United States. Management of this disease has relied on fungicide applications, yet due to the environmental conditions necessary for SSR to develop, many of these applications are unnecessary. To mitigate this, predictive models have been developed using localized weather data for predicting the formation of S. sclerotiorum apothecia, the inoculum source of SSR, and these models were integrated into a decision support system called Sporecaster©...

BACKGROUND: Preclinical evidence suggests that c-Abl is critical in the pathogenesis of Parkinson's Disease (PD). Vodobatinib (K0706) is a potent, specific Abl kinase inhibitor currently being developed for the treatment of PD. In previously reported studies, nilotinib, a multikinase c-Abl inhibitor, did not show clinical activity as evidenced by no improvement of symptoms or the rate of decline after one to six months of treatment at the maximum permissible dose, presumably because of insufficient CNS penetration...

BACKGROUND: Adeno-associated virus (AAV) vectors are a promising platform for in vivo transfer of transgenes designed to treat diseases. Pre-existing humoral immunity to these vectors can potentially impact the safety and efficacy of gene therapies. Consequently, individuals with pre-existing antibodies to the specific AAV serotypes used may be excluded from clinical trials and treatments. Recombinant AAV serotype rh74 (rAAVrh74), a vector originally isolated from rhesus monkeys and potentially less immunogenic than other serotypes isolated from humans (e...

INTRODUCTION: Older patients with cancer often require acute care treatment through emergency department (ED) visits and hospitalizations. This study investigates acute care utilization through ED visits and hospitalizations during treatment and in the two years following the completion of primary treatment for early stage breast cancer (EBC) in women aged 65 and older. MATERIALS AND METHODS: A retrospective analysis including descriptive statistics, univariate analysis, and relative risk analysis of 256 women with EBC was performed through medical record review of demographics, comorbidities, disease characteristics, treatment details, and causes of hospitalizations and ED visits...

Better treatments are needed to improve cognition and brain health in people with mild cognitive impairment (MCI) and Alzheimer's disease (AD). Transcutaneous vagus nerve stimulation (tVNS) may impact brain networks relevant to AD through multiple mechanisms including, but not limited to, projection to the locus coeruleus, the brain's primary source of norepinephrine, and reduction in inflammation. Neuropathological data suggest that the locus coeruleus may be an early site of tau pathology in AD. Thus, tVNS may modify the activity of networks that are impaired and progressively deteriorate in patients with MCI and AD...

PURPOSE OF REVIEW: Atherosclerotic cardiovascular disease (ASCVD) is a leading cause of mortality in adults with type 1 diabetes (T1D). Although dyslipidaemia is a modifiable and prevalent risk factor in individuals with T1D, determining when to initiate lipid-lowering therapy for primary prevention of ASCVD can be challenging. In this article, recommendations for lipid-lowering therapy from updated clinical guidelines over the last 5 years, additional risk-stratification methods, hypertriglyceridaemia management and potential barriers to optimal care in adults with T1D are discussed...

PURPOSE: This study examined differences in Quitline treatment enrollment, engagement, and smoking cessation outcomes among primary care patients preferring Spanish and English using the evidence-based tobacco treatment Ask-Advise-Connect. METHODS: Ask-Advise-Connect was implemented April 2013 through February 2016 in a large safety-net health system to connect smokers with treatment via a link in the electronic health record. Rates of treatment enrollment, engagement, acceptance of nicotine replacement therapy, and smoking abstinence (self-reported and biochemically confirmed) were compared at 6 months among patients who received treatment in Spanish and English using χ 2 tests...

Polarization sensitive optical coherence tomography (PSOCT) has been shown to image and delineate white matter fibers in a label-free manner by revealing optical birefringence within the myelin sheath using a microscope setup. In this proof-of-concept study, we adapt recent advancements in endoscopic PSOCT to perform depth-resolved imaging of white matter structures deep inside intact porcine brain tissue ex-vivo, through a small, rotational fiber probe. The probe geometry is comparable to microelectrodes currently used in neurosurgical interventions...

Firstborn children have higher prevalence of obesity than secondborn siblings. The birth of a sibling typically results in resource dilution when mothers begin to divide their time and attention between two children. This mixed-methods analysis applies the family systems process of resource dilution to test the hypothesis that characteristics of the secondborn impact how parents feed the firstborn. Participants (n = 76) were mothers of consecutively born firstborn and secondborn siblings who participated in the INSIGHT trial and an observational cohort...

RATIONALE: Adult sepsis survivors have an increased risk of experiencing long-term cardiovascular events. OBJECTIVE: To determine whether the cardiovascular risk following sepsis is mitigated by renin-angiotensin system inhibitors (RASi). METHODS: Population-based cohort study of adult sepsis survivors designed to emulate a target randomized trial with an active comparator and new-user design. We excluded patients with a first-line indication for prescription of RASi (e...

UNLABELLED: Abstract BACKGROUND: Granulocyte-macrophage colony-stimulating factor (GM-CSF) and dysregulated myeloid cell responses are implicated in the pathophysiology and severity of coronavirus disease 2019 (COVID-19). METHODS: In this randomised, sequential, multicentre, placebo-controlled, double-blind study, adults aged 18-79 years (Part 1) or ≥70 years (Part 2) with severe COVID-19, respiratory failure, and systemic inflammation (elevated C-reactive protein/ferritin) received a single intravenous infusion of otilimab 90 mg (human anti-GM-CSF monoclonal antibody) plus standard care (NCT04376684)...

BACKGROUND: Patients with relapsed and refractory solid and central nervous system (CNS) tumors have poor outcomes and need novel therapeutic options. Vincristine, irinotecan, and temozolomide (VIT) is a common chemotherapy regimen in relapsed pediatric tumors with an established toxicity profile. Metformin shows preclinical anti-cancer activity through multiple pathways. METHODS: The objective of this Phase I trial was to establish the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D) of metformin in combination with VIT in children with relapsed and refractory solid and CNS tumors...
