PURPOSE: Inadvertent perioperative hypothermia (IPH) is associated with a range of adverse outcomes. Safe and effective warming techniques exist to prevent IPH; however, IPH remains common. This study aimed to identify factors that anesthesiologists perceive may influence temperature management during the perioperative period. METHODS: After Research Ethics Board approval, semi-structured interviews were conducted with staff anesthesiologists at a Canadian academic hospital...

PURPOSE: To evaluate in a proof-of-concept study the feasibility of Simultaneous Noncontrast Angiography and intraPlaque hemorrhage (SNAP) imaging as a clinical magnetic resonance angiography (MRA) technique for measuring carotid stenosis. There is a growing interest in detecting intraplaque hemorrhage (IPH) during the clinical management of carotid disease, yet luminal stenosis has remained indispensable during clinical decision-making. SNAP imaging has been proposed as a novel IPH imaging technique that provides carotid MRA with no added scan time...

BACKGROUND: The Nursing profession is struggling to return to basic nursing care to maintain patients' safety. "Interventional patient hygiene" (IPH) is a measurement model for reducing the bioburden of both the patient and health care worker, and its components are hand hygiene, oral care, skin care/antisepsis, and catheter site care. OBJECTIVES: To identify the level of nurses' practice and knowledge about interventional patient hygiene and identify barriers for implementing interventional patient hygiene in critical care units...

In horses, immune-mediated muscle disorders can arise from an overzealous immune response to concurrent infections or potentially from an inherent immune response to host muscle antigens. Streptococcus equi ss. equi infection or vaccination can result in infarctive purpura hemorrhagica (IPH) in which vascular deposition of IgA-streptococcal M protein complexes produces ischemia and complete focal infarction of skeletal muscle and internal organs. In Quarter Horse-related breeds with immune-mediated myositis, an apparent abnormal immune response to muscle antigens results in upregulation of major histocompatibility complex class (MHC) I and II on muscle cell membranes, lymphocytic infiltration of lumbar and gluteal myofibers, and subsequent gross muscle atrophy...

BACKGROUND AND AIMS: Prospective studies have shown a strong association between carotid intraplaque hemorrhage (IPH), detected by magnetic resonance imaging (MRI), and cerebrovascular ischemic events. However, IPH is also observed in a substantial number of asymptomatic patients. We hypothesized that there are differences in the characteristics of IPH+ plaques associated with recent symptoms, compared to IPH+ plaques not associated with recent symptoms. METHODS: Patients with recent (≤2 weeks) anterior circulation ischemic events were scanned using a standardized multisequence protocol...

We report the outcomes of the reactions of aromatic group 16 thiophene, selenophene, and tellurophene rings with the I(III) oxidants PhI(OAc)(OTf) and [PhI(Pyr)2][OTf]2 (Pyr = pyridine). In all reactions, oxidative processes take place, with generation of PhI as the reduction product. However, with the exception of tellurophene with PhI(OAc)(OTf), +4 oxidation state complexes are not observed, but rather a variety of other processes occur. In general, where a C-H unit is available on the 5-membered ring, an electrophilic aromatic substitution reaction of either -IPh or pyridine onto the ring occurs...

Idiopathic portal hypertension (IPH), causing aberrant portal hemodynamics, is a disease with an as yet unidentified cause and no treatment has been established so far. The Japanese research group on IPH in Japan was set up in 1975 by the Ministry of Health, Labour and Welfare, furthermore extra-hepatic portal obstruction (EHO) and Budd-Chiari syndrome (BCS) have been added to the research subjects and further work has continued. The aims of the research group are to accurately evaluate the current status of the three diseases in Japan, elucidate the disease aetiology and pathogenesis, and develop new treatments...

BACKGROUND: As a systemic disease, atherosclerosis commonly affects intracranial and extracranial carotid arteries simultaneously which is defined as co-existing plaques. Previous studies demonstrated that co-existing atherosclerotic diseases are significantly associated with ischemic cerebrovascular events. The aim of this study was to investigate the characteristics of co-existing intracranial and extracranial carotid atherosclerotic plaques and their relationships with recurrent stroke by using 3D multi-contrast magnetic resonance (MR) vessel wall imaging...

The aim of this study was to compare 3D T2-weighted sampling perfection with application optimized contrast using different flip angle evolutions (T2w SPACE) with conventional 2D T2w turbo-spin echo (TSE) in plaque imaging of carotid artery. 45 patients underwent 3.0-T MRI for carotid arteries imaging. MR sequences included T2w SPACE, T2w TSE, Time of flight (TOF) and T1-weighted (T1w) TSE. The signal intensity of intra-plaque hemorrhage (IPH), lipid-rich necrotic core (LRNC), and loose matrix (LM) were measured and their contrast ratios (CRs) against adjacent muscle were calculated...

BACKGROUND AND AIMS: In a large stroke-free population, we sought to identify cardiovascular risk factors and carotid plaque components associated with carotid plaque burden, lumen volume and stenosis. METHODS: The carotid arteries of 1562 stroke-free participants from The Rotterdam Study were imaged on a 1.5-Tesla MRI scanner. Inner and outer wall of the carotid arteries were automatically segmented and lumen volume (mm(3)), wall volume (outer wall-inner wall) and plaque burden (wall volume/outer wall volume) (%) were quantified...

The aim of this article is to conduct a critical analysis of existing family violence literature related to elder abuse homicide, also known as "eldercide." The focus relates to fatal violence perpetrated by current or former intimates. Men are the most likely victims of homicide but are rarely murdered by partners. Older women are most often killed in the home by a spouse or other family, consistent with the notion of "femicide." The Federal Bureau of Investigation Supplemental Homicide Reports and the Bureau of Justice Statistics National Crime Victimization Survey are utilized to illustrate trends by sex over time...

BACKGROUND AND AIMS: Plaque fissuring, a phenomenon morphologically distinct from the classical rupture of a thinned fibrous cap, has not been well characterized in carotid atherosclerosis. The aim of this study was to establish the prevalence of plaque fissures in advanced carotid plaques with an otherwise intact luminal surface, and to determine whether they might be a source of intraplaque hemorrhage (IPH). METHODS: We evaluated 244 surgically intact, 'en bloc' embedded, serially sectioned carotid endarterectomy specimens and included only those plaques with a grossly intact luminal surface...

A 64-year-old woman treated for anemia and ascites exhibited hepatic encephalopathy. Abdominal ultrasonography and computed tomography (CT) showed communication between the portal vein and the middle hepatic vein, indicating an intrahepatic portosystemic venous shunt (PSS). Since hepatic encephalopathy of the patient was resistant to medical treatment, interventional radiology was performed for the treatment of shunt obliteration. Hepatic venography showed anastomosis between the hepatic vein branches, supporting the diagnosis of idiopathic portal hypertension (IPH)...

BACKGROUND: Idiopathic pulmonary haemosiderosis (IPH) is a rare but potentially lethal condition in paediatric patients. This condition is considered an immune-mediated disorder, but its pathogenesis is still unknown. Idiopathic pulmonary haemosiderosis is characterized by the classical triad of haemoptysis, iron-deficiency anaemia, and diffuse parenchymal consolidation on chest radiology. Unfortunately, this triad of signs is not frequent in children at the onset of this disease, resulting in a delay in diagnosis and a negative outcome...

PURPOSE: The presence of intraparenchymal hyperattenuations (IPH) on flat-panel computed tomography (FP-CT) after endovascular recanalization in stroke patients is a common phenomenon. They are thought to occur in ischemic areas with breakdown of the blood-brain barrier but previous studies that investigated a mutual interaction are scarce. We aimed to assess the relationship of IPH localization with prethrombectomy diffusion-weighted imaging (DWI) lesions. METHODS: This retrospective multicenter study included 27 acute stroke patients who underwent DWI prior to FP-CT following mechanical thrombectomy...

INTRODUCTION: Developmental venous anomalies (DVAs) are cited as the most common cerebral vascular malformations. Still, intracerebral hematomas are rarely thought to be caused by DVAs. In this report, the authors present a unique case of a DVA that hemorrhaged spontaneously, rather than hemorrhaging into a venous infarction following DVA thrombosis as has been more commonly reported. CLINICAL PRESENTATION: A 22-year-old previously healthy male presented to the emergency department with a severe headache, confusion, and progressive hemiparesis...

Internal jugular vein (IJV) compression has been shown to reduce axonal injury in pre-clinical traumatic brain injury (TBI) models and clinical concussion studies. However, this novel approach to prophylactically mitigating TBI through venous congestion raises concerns of increasing the propensity for hemorrhage and hemorrhagic propagation. This study aims to test the safety of IJV compression in a large animal controlled cortical impact (CCI) injury model and the resultant effects on hemorrhage. Twelve swine were randomized to placement of a bilateral IJV compression collar (CCI+collar) or control/no collar (CCI) prior to CCI injury...
