A 1-year- and 11-month-old spayed female toy poodle had showed progressive ataxia and paresis in the hindlimbs since 11 months old. Magnetic resonance imaging revealed high signal intensity on T2-weighted and fluid-attenuated inversion recovery images at the thoracic and lumbar spinal cord. The dog's neurological condition slowly deteriorated and flaccid tetraparesis was exhibited. At 4 years and 11 months old, the dog died of respiratory failure. On postmortem examination, eosinophilic corkscrew bundles (Rosenthal fibers) were observed mainly in the thoracic and lumbar spinal cord. Histological features were comparable to previously reported cases with Alexander disease. This is a first case report to describe the clinical course and long-term prognosis of a dog with Alexander disease.

Comparison of definitions of early knee osteoarthritis for likelihood of progression at 2-year and 5-year follow-up: the Multicenter Osteoarthritis Study.

Background: Preventing worsening osteoarthritis (OA) in persons with early OA is a major treatment goal. We evaluated if different early OA definitions yielded enough cases of worsening OA within 2-5 years to make trial testing treatments feasible.
Methods: We assessed different definitions of early OA using data from Multicenter Osteoarthritis (MOST) Study participants who were followed up longitudinally.
Severe Maternal Morbidity Associated With Chronic Hypertension, Preeclampsia, and Gestational Hypertension.

Importance: Chronic hypertension and preeclampsia are leading risk enhancers for maternal-neonatal morbidity and mortality. Severe maternal morbidity (SMM) indicators include heart, kidney, and liver disease, but studies have not excluded patients with preexisting diseases that define SMM. Thus, SMM risks for uncomplicated chronic hypertension specific to preeclampsia remain unclear.

Pharmaceutical medicine professionals have to face many ethical problems during the entire life span of new medicines extending from animal studies to broad clinical practice. The primary aim of the general ethical principles governing research conducted in humans is to diminish the physical and psychological burdens of the participants in human drug studies but overlooks many additional social and ethical problems faced by medicine developers. These arise mainly at the interface connecting the profit-oriented pharmaceutical industry and the healthcare-centered medical profession cooperating in medicines development.

Understanding the dynamic pathophysiology of diseases in the lung, such as asthma and chronic asthma, chronic obstructive pulmonary disease, and lung cancer, is crucial for the treatment, analysis, and outcome of these diseases. Unlike other traditional models, we suggest a protocol that is sustainable and reproducible and offers different analysis methods while maintaining in vivo lung architecture and immune dynamics. This protocol allows one to study the pathophysiological changes, including changes to the immune cells, cytokines, and mediators, in 30 precision-cut lung slices from a single murine lung.

Background: Research on the contextual drivers of antimicrobial stewardship (AMS) programme interventions in neonatal units is limited.
Methods: As part of a prospective mixed-methods multidisciplinary neonatal AMS (NeoAMS) interventional study in 14 South African hospitals, we applied a three-phased process to assess implementation barriers and contextual drivers experienced by participating health professionals. The study included: (Phase one; P1) a survey of pre-intervention barriers and enablers; (P2) written feedback during the study intervention phase; and (P3) semi-structured exit interviews.
