Health Disparities and Impact of Social Vulnerability on Diagnosis and Outcomes in Vestibular Disorders.

Objectives: Examining the effect of demographics and social vulnerability on diagnosis and management of patients with vestibular and balance disorders.

Design: Retrospective review of a database of patients presenting with vestibular symptoms to a multidisciplinary tertiary vestibular clinic between January and October 2021. Main outcomes included odds ratios of final diagnosis, treatment response, time to presentation by demographic variable, insurance status, residence, and social vulnerability factors according to the 2018 Centers for Disease Control Social Vulnerability Index.

Three new species (, ) described from Antarctic soils.

The genus includes several species frequently isolated from extreme environments worldwide, including cold environments such as Antarctica. This study describes three new species of - , , and -isolated from Antarctic soils. These species represent the first taxa to be formally described from Antarctic soil samples, expanding our understanding of fungal biodiversity in this extreme environment.

Portable Sleep Study Device Versus Polysomnography: A Meta-analysis.

Objective: To provide an updated comparison of apnea-hypopnea index (AHI), oxygen desaturation index (ODI), respiratory disturbance index (RDI), oxygen saturation (O sat), and lowest oxyhemoglobin saturation (LSAT) measured by portable sleep study devices (PSSDs) compared to polysomnography (PSG).

Data Sources: Primary studies were identified through PubMed, Scopus, CINAHL, and Cochrane.

Review Methods: A systematic review was performed by searching databases from inception through August 2021.

Odors: from chemical structures to gaseous plumes.

We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their interactions with the receptor site. But, naturally occurring smells are parsed from gaseous odor plumes.

Extruded gallbladder mucoceles have characteristic ultrasonographic features and extensive migratory capacity in dogs.

Limited information is available on the ultrasonographic characteristics of extruded gallbladder mucoceles. The objective of this retrospective case series study was to describe the ultrasonographic features of extruded gallbladder mucoceles in a group of dogs. Medical records of four veterinary centers were searched between June 2010 and January 2018 for all dogs with a suspected extruded gallbladder mucocele based on abdominal ultrasound.

Comparison of two fat-suppressed magnetic resonance imaging pulse sequences to standard t2-weighted images for brain parenchymal contrast and lesion detection in dogs with inflammatory intracranial disease.

T2-weighted (T2w) sequences are commonly relied upon in magnetic resonance imaging protocols for the detection of brain lesions in dogs. Previously, the effect of fluid suppression via fluid-attenuated inversion recovery (FLAIR) has been compared to T2-weighting with mixed results. Short tau inversion recovery (STIR) has been reported to increase the detection of some CNS lesions in people.

Echocardiographic and radiographic findings in a cohort of healthy adult green iguanas (Iguana iguana).

Objectives: To describe characteristics of echocardiography and cranial coelomic radiography in a cohort of iguanas.

Animals: Twenty apparently healthy adult green iguanas (Iguana iguana) from a reptile sanctuary.

Methods: Physical examination, radiography, two-dimensional and color Doppler echocardiography were performed to assess cardiac structures and function, and any related normal or abnormal findings were recorded.

Smelling phenomenal.

Qualitative-consciousness arises at the sensory level of olfactory processing and pervades our experience of smells to the extent that qualitative character is maintained whenever we are aware of undergoing an olfactory experience. Building upon the distinction between Access and Phenomenal Consciousness the paper offers a nuanced distinction between Awareness and Qualitative-consciousness that is applicable to olfaction in a manner that is conceptual precise and empirically viable. Mounting empirical research is offered substantiating the applicability of the distinction to olfaction and showing that olfactory qualitative-consciousness can occur without awareness, but any olfactory state that we are aware of being in is always qualitative.

Quality-space theory in olfaction.

Quality-space theory (QST) explains the nature of the mental qualities distinctive of perceptual states by appeal to their role in perceiving. QST is typically described in terms of the mental qualities that pertain to color. Here we apply QST to the olfactory modalities.

Evaluation of standard magnetic resonance characteristics used to differentiate neoplastic, inflammatory, and vascular brain lesions in dogs.

Magnetic resonance (MR) imaging characteristics are commonly used to help predict intracranial disease categories in dogs, however, few large studies have objectively evaluated these characteristics. The purpose of this retrospective study was to evaluate MR characteristics that have been used to differentiate neoplastic, inflammatory, and vascular intracranial diseases in a large, multi-institutional population of dogs. Medical records from three veterinary teaching hospitals were searched over a 6-year period for dogs that had diagnostic quality brain MR scans and histologically confirmed intracranial disease.

Comparison between noncontrast computed tomography and magnetic resonance imaging for detection and characterization of thoracolumbar myelopathy caused by intervertebral disk herniation in dogs.

Magnetic resonance imaging (MRI) and computed tomography (CT) are commonly used to evaluate dogs with thoracolumbar myelopathy; however, relative diagnostic sensitivities for these two modalities have not been previously reported. The purpose of this prospective study was to compare diagnostic sensitivity and observer agreement for MRI and CT in a group of dogs with thoracolumbar myelopathy due to surgically confirmed intervertebral disk herniation (IVDH). All included dogs had magnetic resonance (MR) imaging followed by noncontrast CT using standardized protocols.

Thoracic and lumbar spinal cord diffusion tensor imaging in dogs.

Purpose: To analyze four clinically applicable diffusion tensor imaging (DTI) protocols (two each in the transverse and sagittal planes) in the normal dog.

Materials And Methods: Seven healthy Dachshund dogs were scanned with four DTI protocols. Within each plane, identical spatial resolution was used while the number of diffusion-encoding directions and averages varied.

Cytologic diagnosis of disseminated histoplasmosis in the wall of the urinary bladder of a cat.

A 10 yr old domestic longhair presented with a 2.5 mo history of recurrent hematuria. Abdominal ultrasound examination demonstrated a thickened urinary bladder, abdominal lymphadenopathy, and a thickened and rounded spleen.

Comparison of intraosseous and peripheral venous fluid dynamics in the desert tortoise (Gopherus agassizii).

The efficacy of intraosseous catheterization has not been described previously in the desert tortoise (Gopherus agassizii). The goal of this study was to describe and compare the efficacy of four intraosseous catheter sites (humerus, femur, plastocarapacial junction [bridge], and gular region of the plastron) to jugular catheterization. Five adult tortoises were catheterized in each of the sites at least once.

MRI characteristics of cerebral microbleeds in four dogs.

Cerebral microbleeds in people are small foci of hemosiderin-containing macrophages in normal brain parenchyma. They are the remnant of previous hemorrhage and occur with greater frequency in older individuals. Our purpose was to describe the magnetic resonance (MR) appearance of cerebral microbleeds in four dogs.
