Overexpression of autophagy enhancer PACER/RUBCNL in neurons accelerates disease in the SOD1 ALS mouse model.

Amyotrophic lateral sclerosis (ALS) is a debilitating and fatal paralytic disorder associated with motor neuron death. Mutant superoxide dismutase 1 (SOD1) misfolding and aggregation have been linked to familial ALS, with the accumulation of abnormal wild-type SOD1 species being also observed in postmortem tissue of sporadic ALS cases. Both wild-type and mutated SOD1 are reported to contribute to motoneuron cell death.

Proximal fibular physeal stress injury: a known entity in an unusual location.

In the skeletally immature patient, physeal stress injury is a common diagnosis in repetitive stress injury; in this case, we present an atypical location of physeal stress injury of the bilateral proximal fibulae. There are multiple well-documented diagnoses of physeal stress injury involving the shoulder, elbow, wrist and tibia, often considered when patients present with the typical history of intensive sports training and pain exacerbated by repetitive movements. However, isolated proximal fibular physeal stress injury is either unusual or under-recognized and underreported.

A "Bumper-Car" Curriculum for Teaching Deep Learning to Radiology Residents.

Rationale And Objectives: Our goal was to create an artificial intelligence (AI) training curriculum for residents that taught them to create, train, evaluate and refine deep learning (DL) models. Hands-on training of models was emphasized and didactic presentations of the mathematical and programmatic underpinnings of DL were minimized.

Materials And Methods: We created a three-session, 6-hour curriculum based on a "no-code" machine learning system called Lobe.

Severe Acute Kidney Injury Secondary to Immunoglobulin Infusion in Life-Threatening Guillain Barre Syndrome.

Immunoglobulin infusion (IVIG) is one of the first line therapy in Guillain Barre Syndrome (GBS). Several medical complications are associated with GBS (pneumonia, sepsis, deep vein thrombosis, dysautonomy). Acute kidney injury (AKI) is an uncommon complication during IVIG infusion.

Is There a Difference Between LI-RADS 3 to LI-RADS 5 Progression Assessment Using CT Versus MR? A Retrospective, Single-Center, Longitudinal Study of Patients Who Underwent 5082 Radiologic Examinations for Surveillance of Hepatocellular Carcinoma Over a 43-Month Period.

Objective: The Liver Imaging Reporting and Data System (LI-RADS) has been widely applied to CT and MR liver observations in patients at high-risk for hepatocellular carcinoma (HCC). We investigated the impact of CT vs MR in upgrading LI-RADS 3 to LI-RADS 5 observations using a large cohort of high-risk patients.

Methods: We performed a retrospective, longitudinal study of CT and MR radiographic reports (June 2013 - February 2017) with an assigned LI-RADS category.

Protein disulfide isomerase ERp57 protects early muscle denervation in experimental ALS.

Amyotrophic lateral sclerosis (ALS) is a progressive fatal neurodegenerative disease that affects motoneurons. Mutations in superoxide dismutase 1 (SOD1) have been described as a causative genetic factor for ALS. Mice overexpressing ALS-linked mutant SOD1 develop ALS symptoms accompanied by histopathological alterations and protein aggregation.

Rectothecal fistula complicating anterior sacral meningocele repair.

We present a case of an iatrogenic rectothecal fistula in a 34-year-old man who underwent repair of a congenital anterior sacral meningocele, intraoperatively complicated by rectal perforation. Postoperatively, the patient developed symptoms of meningitis prompting concern for the cerebrospinal fluid leak. Subsequent workup with computed tomography (CT) and magnetic resonance imaging demonstrated a postoperative pseudomeningocele and fistulization with an abdominal fluid collection.

Small Intestine Microbiota Regulate Host Digestive and Absorptive Adaptive Responses to Dietary Lipids.

The gut microbiota play important roles in lipid metabolism and absorption. However, the contribution of the small bowel microbiota of mammals to these diet-microbe interactions remains unclear. We determine that germ-free (GF) mice are resistant to diet-induced obesity and malabsorb fat with specifically impaired lipid digestion and absorption within the small intestine.

Post discharge issues identified by a call-back program: identifying improvement opportunities.

Objectives: The period following discharge from the hospital is one of heightened vulnerability. Discharge instructions serve as a guide during this transition. Yet, clinicians receive little feedback on the quality of this document that ties into the patients' experience.

Nutritional modulation of gut microbiota - the impact on metabolic disease pathophysiology.

The obesity epidemic afflicts over one third of the United States population. With few therapies available to combat obesity, a greater understanding of the systemic causes of this and other metabolic disorders is needed to develop new, effective treatments. The mammalian intestinal microbiota contributes to metabolic processes in the host.
