Diagnostic quality of ultrasound-guided fine-needle aspirates samples from the canine liver and spleen is not significantly affected by using 22-, 23-, and 25-gauge needles.

Ultrasound-guided fine-needle aspirates (FNA) of the liver and spleen for cytological analysis are a commonly performed procedure in canine veterinary practice. Based on our review of the literature, this is the first published study investigating whether needle size affects the diagnostic quality of hepatic and splenic samples. The aim of this prospective analytical study was to compare the diagnostic quality of ultrasound-guided FNA cytological samples of canine liver and spleen based on cellularity, blood contamination, and overall cell preservation between three different needle sizes (22-, 23-, and 25-gauge).

Survey of factors affecting satisfaction and success of residents enrolled in European College of Veterinary Diagnostic Imaging (ECVDI) residency programs.

Several published studies have described the success and satisfaction of residents enrolled in human radiology training programs, however comparable studies for veterinary radiology residents are currently lacking. The purpose of this descriptive, survey study was to evaluate resident perceptions of the European College of Veterinary Diagnostic Imaging (ECVDI) residency training programs. A web-based survey was sent to all listed 114 ECVDI residents and received a 57.

Prevalence of Trauma-Induced Hypocalcemia in the Prehospital Setting.

Background: Recent data published by the Special Operations community suggest the Lethal Triad of Trauma should be changed to the Lethal Diamond, to include coagulopathy, acidosis, hypothermia, and hypocalcemia. The purpose of this study is to determine the prevalence of trauma-induced hypocalcemia in level I and II trauma patients.

Methods: This is a retrospective cohort study conducted at a level I trauma center and Special Operations Combat Medic (SOCM) training site.

Assessing the Impact of a Shinrin-Yoku (Forest Bathing) Intervention on Physician/Healthcare Professional Burnout: A Randomized, Controlled Trial.

Professional healthcare worker burnout is a crisis in the United States healthcare system. This crisis can be viewed at any level, from the national to local communities, but ultimately, must be understood at the level of the individual who is caring for patients. Thus, interventions to reduce burnout symptoms must prioritize the mental health of these individuals by alleviating some of the symptoms of depression, grief, and anxiety that accompany burnout.

The Implementation of a Stress Management Program for Health Care Workers Through a Rural Occupational Health Clinic.

Background: Stress affects U.S. healthcare workers (HCWs) and costs US$191 billion annually.

Variation in the MRI appearance of the canine pituitary gland.

A recent publication described pathological findings in the pituitary gland incidentally discovered during routine necropsies of the brain of dogs and cats; however, imaging characteristics of these lesions were not reported. Aims of this retrospective, observational study were to characterize MRI variants and incidental lesions in pituitary glands of dogs with no clinical signs of pituitary disease. Cranial MRIs from dogs with no suspicion of pituitary disease, based on history and presenting clinical signs, were retrieved from a veterinary teleradiology database during the period of January 2014 to January 2016.

MRI findings of neuronal ceroid lipofuscinosis in a cat.

Case Summary: A 2-year-old male domestic shorthair cat presented to the University of Liverpool Small Animal Teaching Hospital with a 2 week history of altered mentation, blindness and focal epileptic seizures. MRI examination revealed generalised cerebral and cerebellar atrophy, diffuse T2-weighted hyperintensity of the white matter and meningeal thickening. Neuronal ceroid lipofuscinosis was confirmed on post-mortem examination.

Computed tomographic findings in three dogs naturally infected with Crenosoma vulpis.

Crenosoma vulpis is a nematode lungworm found in wild and domestic canids in some parts of North America and Europe. Reported radiographic findings are nonspecific and consist of a combination of bronchial and interstitial changes of variable severity. This retrospective, case series study aimed to describe thoracic computed tomographic (CT) findings for a group of dogs with confirmed crenosomosis.

Practical and Legal Challenges to Electroconvulsive Therapy in Malignant Catatonia.

In cases of malignant catatonia, prompt administration of electroconvulsive therapy (ECT) can decrease mortality, whereas delays to initiating ECT have resulted in adverse outcomes, including death. We present a clinical vignette of malignant catatonia that required court-ordered ECT, followed by a discussion of practical and legal obstacles to expediting emergent ECT when patients cannot provide consent. We review particularly exacting mandates for involuntary ECT from three states: California, Texas, and New York.

Intensive care unit patients in the postanesthesia care unit: a case study exploring nurses' experiences.

Purpose: The purpose of this study was to understand the experiences of postanesthesia nurses caring for intensive care unit (ICU) patients in the postanesthesia care unit (PACU).

Design: Qualitative interpretive description.

Methods: Six PACU nurses participated in semi-structured interviews.

A psychopharmacology course for psychiatry residents utilizing active-learning and residents-as-teachers to develop life-long learning skills.

Objective: The authors describe the implementation and evaluation of a 1-year psychopharmacology course using residents-as-teachers and active-learning exercises intended to improve understanding of current psychopharmacology and its evidence base, and skills for life-long learning.

Method: Weekly classes were devoted to psychotropic medications, treating specific disorders, and use of psychotropics in special patient populations. Each class was divided into three sections: a pharmacology review, a literature review and a faculty-led discussion of clinical questions.

Neurofibromatosis-1 heterozygosity increases microglia in a spatially and temporally restricted pattern relevant to mouse optic glioma formation and growth.

Whereas carcinogenesis requires the acquisition of driver mutations in progenitor cells, tumor growth and progression are heavily influenced by the local microenvironment. Previous studies from our laboratory have used Neurofibromatosis-1 (NF1) genetically engineered mice to characterize the role of stromal cells and signals to optic glioma formation and growth. Previously, we have shown that Nf1+/- microglia in the tumor microenvironment are critical cellular determinants of optic glioma proliferation.

Neurofibromatosis-1 regulates neuroglial progenitor proliferation and glial differentiation in a brain region-specific manner.

Recent studies have shown that neuroglial progenitor/stem cells (NSCs) from different brain regions exhibit varying capacities for self-renewal and differentiation. In this study, we used neurofibromatosis-1 (NF1) as a model system to elucidate a novel molecular mechanism underlying brain region-specific NSC functional heterogeneity. We demonstrate that Nf1 loss leads to increased NSC proliferation and gliogenesis in the brainstem, but not in the cortex.

Reduced striatal dopamine underlies the attention system dysfunction in neurofibromatosis-1 mutant mice.

Learning and behavioral abnormalities are among the most common clinical problems in children with the neurofibromatosis-1 (NF1) inherited cancer syndrome. Recent studies using Nf1 genetically engineered mice (GEM) have been instructive for partly elucidating the cellular and molecular defects underlying these cognitive deficits; however, no current model has shed light on the more frequently encountered attention system abnormalities seen in children with NF1. Using an Nf1 optic glioma (OPG) GEM model, we report novel defects in non-selective and selective attention without an accompanying hyperactivity phenotype.

Crack propagation in teeth: a comparison of perimortem and postmortem behavior of dental materials and cracks.

This study presents a new method for understanding postmortem heat-induced crack propagation patterns in teeth. The results demonstrate that patterns of postmortem heat-induced crack propagation differ from perimortem and antemortem trauma-induced crack propagation patterns. Dental material of the postmortem tooth undergoes dehydration leading to a shrinking and more brittle dentin material and a weaker dentin-enamel junction.

Loss of the protein NUPR1 (p8) leads to delayed LHB expression, delayed ovarian maturation, and testicular development of a sertoli-cell-only syndrome-like phenotype in mice.

The high mobility group factor NUPR1, also known as p8 and com1, plays a role in temporal expression of the beta subunit of luteinizing hormone, LHB, during gonadotroph development. At Embryonic Day (e) 16.5, LHB is detectable in wild-type (Nupr1(+/+)) but not Nupr1 knockout (Nupr1(-/-)) mice.
