A Patient With Symptomatic Pheochromocytoma and Very Severe Aortic Valve Stenosis: Diagnostic and Management Approach.

Preoperative management of a pheochromocytoma involves α-adrenergic receptor blockers and volume expansion followed by β-adrenergic receptor blockers and then adrenalectomy, which in the presence of very severe aortic valve stenosis would be challenging. We describe a patient with this rare combination who underwent pharmacotherapy followed by transcatheter aortic valve replacement and then adrenalectomy, culminating in a successful outcome for this patient.

Mental health and associated risk factors of Puerto Rico Post-Hurricane María.

Background: Mental health disorders have an increased prevalence in communities that experienced devastating natural disasters. Maria, a category 5 hurricane, struck Puerto Rico on September 20, 2017, weakening the island's power grid, destroying buildings and homes, and limiting access to water, food, and health care services. This study characterized sociodemographic and behavioral variables and their association with mental health outcomes in the aftermath of Hurricane Maria.

Post-Hurricane Distress Scale (PHDS): Determination of General and Disorder-Specific Cutoff Scores.

The Post-Hurricane Distress Scale (PHDS) was developed to assess mental health risk in the aftermath of hurricanes. We derive both disorder-specific cutoff values and a single nonspecific cutoff for the PHDS for field use by disaster relief and mental health workers. Data from 672 adult residents of Puerto Rico, sampled 3 to 12 months after Hurricane Maria, were collected.

The Correlation of English Language Proficiency and Indices of Stress and Anxiety in Migrants from Puerto Rico after Hurricane Maria: A Preliminary Study.

Objective: Using validated psychological assessment instruments, this study examined the psychological distress associated with potential language barriers experienced by over 135 000 Puerto Rican residents who either temporarily or permanently migrated to the continental United States with the landfall of Hurricane Maria in 2017.

Methods: Participants were Puerto Rican residents (n = 107) who remained in Puerto Rico (control) or left the island for at least 3 months because of Hurricane Maria (migrants). Participants completed an online survey in their preferred language (Spanish or English), which assessed self-reported English language proficiency, Kessler Psychological Distress Scale (K6), Posttraumatic Stress Disorder Checklist for DSM 5, Patient Health Questionnaire 9-item depression scale, and the Generalized Anxiety Disorder 7-item scale.

Post-Hurricane Distress Scale (PHDS): A Novel Tool for First Responders and Disaster Researchers.

Objective: The aim of this study was the construction and validation of a novel research instrument to quantify the degree of post-hurricane trauma and distress in an affected population. The Post-Hurricane Distress Scale (PHDS) has quantitative measures of both acute and prolonged distress, attributable to meteorological and hydrological disasters.

Methods: A careful evaluation of existing questionnaires, as well as extensive canvasing of the post-Maria population of Puerto Rico, availed the construction of the PHDS.

Comprehensive review of neuromyelitis optica and clinical characteristics of neuromyelitis optica patients in Puerto Rico.

Neuromyelitis optica (NMO) is an immune-mediated inflammatory disorder of the central nervous system. It is characterized by concurrent inflammation and demyelination of the optic nerve (optic neuritis [ON]) and the spinal cord (myelitis). Multiple studies show variations in prevalence, clinical, and demographic features of NMO among different populations.

Role of protein phosphatase 2A in regulating the visual signaling in Drosophila.

Drosophila visual signaling, a G-protein-coupled phospholipase Cbeta (PLCbeta)-mediated mechanism, is regulated by eye-protein kinase C (PKC) that promotes light adaptation and fast deactivation, most likely via phosphorylation of inactivation no afterpotential D (INAD) and TRP (transient receptor potential). To reveal the critical phosphatases that dephosphorylate INAD, we used several biochemical analyses and identified protein phosphatase 2A (PP2A) as a candidate. Importantly, the catalytic subunit of PP2A, microtubule star (MTS), is copurified with INAD, and an elevated phosphorylation of INAD by eye-PKC was observed in three mts heterozygotes.
