Open design of a reproducible videogame controller for MRI and MEG.

Videogames are emerging as a promising experimental paradigm in neuroimaging. Acquiring gameplay in a scanner remains challenging due to the lack of a scanner-compatible videogame controller that provides a similar experience to standard, commercial devices. In this paper, we introduce a videogame controller designed for use in the functional magnetic resonance imaging as well as magnetoencephalography.

Individualizing Breast Cancer Risk Assessment in Clinical Practice.

Multiple tools exist to assess a patient's breast cancer risk. The choice of risk model depends on the patient's risk factors and how the calculation will impact care. High-risk patients-those with a lifetime breast cancer risk of ≥20%-are, for instance, eligible for supplemental screening with breast magnetic resonance imaging.

Ecotoxicology of mercury concentrations in arctic lamprey (Lethenteron camtschaticum).

Arctic lamprey (Lethenteron camtschaticum) is an important dietary resource for rural and indigenous communities in parts of Alaska, with some commercial use. As with many fish species harvested for human consumption, there are concerns regarding mercury concentrations ([Hg]) in Arctic lamprey that may impact human health. To date, information regarding the life cycle and diet of Arctic lamprey is scarce, with no published studies examining [Hg] in Arctic lamprey tissues.

Comparison of Two Total Mercury Screening and Assessment Methods in Fishes: Biopsy Punch and Dried Muscle Samples.

Rapid and effective quantification of total mercury concentrations ([THg]) in fish muscle is an important part of ongoing monitoring to provide reliable and near real-time public health guidance. Methods for quantifying THg in fish muscle frequently require the use of large sample mass and numerous preparation steps. Wet (aka fresh weight) biopsy punch samples of fish muscle have been used to quantify THg directly, without drying and homogenization.

Breast Implants Decrease Chest Wall Trauma in Low-speed, Unrestrained Motor Vehicle Crash: An Experimental Model.

Unlabelled: Breast implants improve quality of life in patients seeking improved breast aesthetics, and are known to minimize human injury in the less common scenario of penetrating trauma. People commonly sustain rib and sternum fractures and thoracic injury in motor vehicle crashes (MVC), a form of blunt traumatic injury. Whether breast implants minimize injury during MVC is unknown.

Incorporation of 53BP1 into phase-separated bodies in cancer cells during aberrant mitosis.

53BP1 (also known as TP53BP1) is a key mediator of the non-homologous end joining (NHEJ) DNA repair pathway, which is the primary repair pathway in interphase cells. However, the mitotic functions of 53BP1 are less well understood. Here, we describe 53BP1 mitotic stress bodies (MSBs) formed in cancer cell lines in response to delayed mitosis.

Lipidomic signatures align with inflammatory patterns and outcomes in critical illness.

Alterations in lipid metabolism have the potential to be markers as well as drivers of pathobiology of acute critical illness. Here, we took advantage of the temporal precision offered by trauma as a common cause of critical illness to identify the dynamic patterns in the circulating lipidome in critically ill humans. The major findings include an early loss of all classes of circulating lipids followed by a delayed and selective lipogenesis in patients destined to remain critically ill.

Ecotoxicology of mercury in burbot (Lota lota) from interior Alaska and insights towards human health.

Fish consumption has many health benefits, but exposure to contaminants, such as mercury (Hg), in fish tissue can be detrimental to human health. The Tanana River drainage, Alaska, USA supports the largest recreational harvest of burbot (Lota lota) in the state, yet information to evaluate the potential risks of consumption by humans is lacking. To narrow this knowledge gap, we sought to (i) quantify the concentrations of total Hg ([THg]) in burbot muscle and liver tissue and the ratio between the two tissues, (ii) assess the effect of age, length, and sex on [THg] in muscle and liver tissue, (iii) evaluate if [THg] in muscle tissue varied based on trophic information, and (iv) compare observed [THg] to consumption guidelines and statewide baseline data.

Correlation between knee anatomy and joint laxity using principal component analysis.

Knee articular geometry and surface morphology greatly affect knee joint mechanics. Intra-subject variations in bone morphology and the passive range of motion have been well documented in the literature; however, the relationship between these two characteristics is not well understood. The objective of this study was to describe the correlation between knee joint anatomical features and passive range of motion using a statistical model.

Multi-omic analysis in injured humans: Patterns align with outcomes and treatment responses.

Trauma is a leading cause of death and morbidity worldwide. Here, we present the analysis of a longitudinal multi-omic dataset comprising clinical, cytokine, endotheliopathy biomarker, lipidome, metabolome, and proteome data from severely injured humans. A "systemic storm" pattern with release of 1,061 markers, together with a pattern suggestive of the "massive consumption" of 892 constitutive circulating markers, is identified in the acute phase post-trauma.

Motivators, Barriers, and Opportunity for E-Health to Encourage Physical Activity in Axial Spondyloarthritis: A Qualitative Descriptive Study.

Objective: Physical activity is fundamental in the management of axial spondyloarthritis (SpA); however, evidence suggests that patients with axial SpA are not adhering to physical activity recommendations. E-health technology (e.g.

An absence of equipoise: Examining surgeons' decision talk during encounters with women considering breast cancer surgery.

Shared decision-making is recommended for decisions with multiple reasonable options, yet clinicians often subtly or explicitly guide choices. Using purposive sampling, we performed a secondary analysis of 142 audio-recorded encounters between 13 surgeons and women eligible for breast-conserving surgery with radiation or mastectomy. We trained 9 surgeons in shared decision-making and provided them one of two conversation aids; 4 surgeons practiced as usual.

Case Report: Propranolol Therapy for Infantile Tremor Syndrome in a Child With Vitamin B12 Deficiency.

Vitamin B12 deficiency in childhood presents with a wide variety of symptoms including anemia, failure to thrive and developmental delays. It is a diagnostic consideration in children who are exclusively breastfed or have minimal solid intake, especially if their mother is vegetarian or has underlying vitamin B12 deficiency. Infantile tremor syndrome (ITS) has been associated with vitamin B12 deficiency.

Cervical Spine, Upper Extremity Neuropathies, and Overuse Injuries in Cyclists.

Upper extremity nerve injuries in cyclists include carpal tunnel syndrome and ulnar neuropathy at the wrist. Electromyography and nerve conduction studies aid in the diagnosis of neuropathies. Diagnostic ultrasonography or MRI can also be helpful for evaluation.

Establishing best practices in cancer online support groups: protocol for a realist review.

Introduction: Considerable observational evidence suggests that cancer online support groups reduce feelings of isolation, depression and anxiety, enhance coping and self-management, and lead to better informed patients. Other studies indicate that cancer online support groups can increase distress. Yet no studies theorise the complex, context-dependent mechanisms by which cancer online support groups generate their-sometimes contrasting-outcomes.

A Case Report of External Cardiac Pads Used for Internal Cardiac Defibrillation During Resuscitative Thoracotomy.

This is a case report regarding the use of non-conventional methods to perform internal cardiac defibrillation on a trauma patient in an austere environment. The patient was a polytrauma causality of an improvised explosive device who arrived to a far forward resuscitative surgical team during a recent armed conflict. After arrival, the patient lost pulses.

An Inconsistent Canadian Provincial and Territorial Response During the Early COVID-19 Pandemic.

According to the World Health Organization (WHO), an early and consistent international and national response is needed to control a pandemic's spread. In this analysis, we evaluate the coordination of Canada's early response to the coronavirus (COVID-19) pandemic in terms of public health interventions and policies implemented in each province and territory. Retrospective data was obtained from publicly accessible websites maintained by federal, provincial and territorial governmental agencies.

Circulating Metabolomic Analysis following Cecal Ligation and Puncture in Young and Aged Mice Reveals Age-Associated Temporal Shifts in Nicotinamide and Histidine/Histamine Metabolic Pathways.

Introduction: Aged individuals are at higher risk for morbidity and mortality following acute stressors than similarly stressed young people. Evaluation of age-associated metabolic changes could lead to the identification of specific therapeutic targets to improve outcomes from acute stressors, such as infections, in the elderly. We thus compared the plasma metabolomes of both young and old mice following cecal ligation and puncture (CLP), an accepted model of acute infection and stress.
