Human trafficking screening in Saskatoon Emergency Departments: What can be learned from high-risk patient presentations?

Objective: Studies have shown that Emergency Department physicians have little to no training in recognizing and supporting victims of human trafficking despite being uniquely situated to identify and intervene on behalf of these patients. We assessed if screening for human trafficking was being completed by emergency physicians in three Saskatoon emergency departments.

Methods: We performed a retrospective chart review of patients presenting to three Saskatoon emergency departments deemed to potentially be at risk of human trafficking, based on discharge diagnosis.

Identifying and addressing the needs of caregivers of patients with cancer: evidence on interventions and the role of patient advocacy groups.

As the number of people with cancer increases, so does the number of informal caregivers. These caregivers frequently have multiple unmet needs and experience numerous burdens. Here we explore the crucial roles of these caregivers and categorize their unmet needs into four areas: information, relationship and communication, emotional support, and practical or financial needs.

A comparison of self-triage tools to nurse driven triage in the emergency department.

Introduction: Canadian patients presenting to the emergency department (ED) typically undergo a triage process where they are assessed by a specially trained nurse and assigned a Canadian Triage and Acuity Scale (CTAS) score, indicating their level of acuity and urgency of assessment. We sought to assess the ability of patients to self-triage themselves through use of one of two of our proprietary self-triage tools, and how this would compare with the standard nurse-driven triage process.

Methods: We enrolled a convenience sample of ambulatory ED patients aged 17 years or older who presented with chief complaints of chest pain, abdominal pain, breathing problems, or musculoskeletal pain.

Immunocontraceptive Efficacy of Native Porcine Zona Pellucida (pZP) Treatment of Nevada's Virginia Range Free-Roaming Horse Population.

In North America, range constraints due to burgeoning development increasingly encroach on wild horse habitat and necessitate effective but humane reproductive management. The largest free-roaming wild horse fertility control program by population (>3500) and territory size (≈300,000 acres) is located within Nevada's Virginia Range. Data from a field study investigated porcine zona pellucida (pZP) immunocontraception via remote dart delivery to mares in this population.

Performance of an automated ultrasound device in identifying and tracing the heart in porcine cardiac arrest.

Background: While intra-arrest echocardiography can be used to guide and monitor chest compression quality, it is not currently feasible on the scene of out-of-hospital cardiac arrests. Rapid and automated sonographic localization of the heart may provide first-responders guidance to an optimal area of compression without requiring them to interpret ultrasound images. In this proof-of-concept porcine study, we sought to describe the performance of an automated ultrasound device in correctly identifying and tracing the borders of the heart in three distinct states: pre-arrest, arrest, and late arrest.

Vessel-encoded arterial spin labeling (VE-ASL) reveals elevated flow territory asymmetry in older adults with substandard verbal memory performance.

Purpose: To evaluate how flow territory asymmetry and/or the distribution of blood through collateral pathways may adversely affect the brain's ability to respond to age-related changes in brain function. These patterns have been investigated in cerebrovascular disease; however, here we evaluated how flow-territory asymmetry related to memory generally in older adults.

Materials And Methods: A multi-faceted MRI protocol, including vessel-encoded arterial spin labeling capable of flow territory mapping, was applied to assess how flow territory asymmetry; memory performance (CERAD-Immediate Recall); cortical cerebral blood flow (CBF), white matter lesion (WML) count, and cortical gray matter volume were related in older healthy control volunteers (HC; n = 15; age = 64.

Inverse correspondence between hippocampal perfusion and verbal memory performance in older adults.

Understanding physiological changes that precede irreversible tissue damage in age-related pathology is central to optimizing treatments that may prevent, or delay, cognitive decline. Cerebral perfusion is a tightly regulated physiological property, coupled to tissue metabolism and function, and abnormal (both elevated and reduced) hippocampal perfusion has been reported in a range of cognitive disorders. However, the size and location of the hippocampus complicates perfusion quantification, as many perfusion techniques acquire data with spatial resolution on the order of or beyond the size of the hippocampus, and are thus suboptimal in this region (especially in the presence of hippocampal atrophy and reduced flow scenarios).

Adverse effects of serotonin depletion in developing zebrafish.

In this study, p-chlorophenylalanine (pCPA), an inhibitor of tryptophan hydroxylase (the rate limiting enzyme of serotonin synthesis), was used to reduce serotonin (5HT) levels during early development in zebrafish embryos. One day old dechorionated embryos were treated with 25 μM pCPA for 24h and subsequently rescued. Immunohistological studies using a 5HT antibody confirmed that 5HT neurons in the brain and spinal cord were depleted of transmitter by 2 days post fertilization (dpf).

GLD-2/RNP-8 cytoplasmic poly(A) polymerase is a broad-spectrum regulator of the oogenesis program.

Regulated polyadenylation is a broadly conserved mechanism that controls key events during oogenesis. Pivotal to that mechanism is GLD-2, a catalytic subunit of cytoplasmic poly(A) polymerase (PAP). Caenorhabditis elegans GLD-2 forms an active PAP with multiple RNA-binding partners to regulate diverse aspects of germline and early embryonic development.

Increased antibodies for the alpha7 subunit of the nicotinic receptor in schizophrenia.

One of the etiological theories of schizophrenia is dysregulation of the immune system. Autoantibodies specific for the alpha7 subunit of the nicotinic receptor could potentially contribute to the pathophysiology of the disease. In this study, positive antibodies specific for the receptor were found to exist in 23% of the patients diagnosed with schizophrenia (n=21).

Adulthood olanzapine treatment fails to alleviate decreases of ChAT and BDNF RNA expression in rats quinpirole-primed as neonates.

Neonatal quinpirole (dopamine D(2)/D(3) agonist) treatment to rats has been shown to increase dopamine D(2) receptor sensitivity throughout the animal's lifetime. Male and female Sprague-Dawley rats were neonatalally treated with quinpirole (1 mg/kg) from postnatal days (P) 1-21 and raised to adulthood. Beginning on P62, rats were administered the atypical antipsychotic olanzapine (2.

Movement disorders and neurochemical changes in zebrafish larvae after bath exposure to fluoxetine (PROZAC).

This study examines the effects of the selective serotonin reuptake inhibitor (SSRI), fluoxetine (PROZAC), on the ontogeny of spontaneous swimming activity (SSA) in developing zebrafish. The development of zebrafish motor behavior consists of four sequential locomotor patterns that develop over 1-5 days post fertilization (dpf), with the final pattern, SSA, established at 4-5 dpf. In stage specific experiments, larvae were exposed to 4.

Chemical eluates from ultra-high molecular weight polyethylene and fibroblast proliferation.

Although polyethylene wear particles have been implicated in osteolysis and implant loosening, this study is the first to test whether chemical eluates extracted from ultra-high molecular weight polyethylene (UHMWPE) could also be involved in this process. Eluates were prepared from UHMWPE bar stock and examined for their effects on (3)H-thymidine incorporation by human foreskin fibroblasts grown in 96-well culture plates. Low concentrations of eluates stimulated (3)H-thymidine uptake; whereas, high concentrations inhibited uptake in a dose-dependent manner.
