Oral Monomethyl Fumarate Therapy Ameliorates Retinopathy in a Humanized Mouse Model of Sickle Cell Disease.

Aims: Sickle retinopathy (SR) is a major cause of blindness in sickle cell disease (SCD). The genetic mutation responsible for SCD is known, however; oxidative stress and inflammation also figure prominently in the development and progression of pathology. Development of therapies for SR is hampered by the lack of (a) animal models that accurately recapitulate human SR and (b) strategies for noninvasive yet effective retinal drug delivery.

Cost-Effectiveness of Long-Acting Injectable Paliperidone Palmitate Versus Haloperidol Decanoate in Maintenance Treatment of Schizophrenia.

Objective: This study assessed the relative cost-effectiveness of haloperidol decanoate (HD), a first-generation long-acting injectable (LAI) antipsychotic, and paliperidone palmitate (PP), a second-generation LAI antipsychotic.

Methods: A double-blind, randomized 18-month clinical trial conducted at 22 clinical research sites in the United States compared the cost-effectiveness of HD and PP among 311 adults with schizophrenia or schizoaffective disorder who had been clinically assessed as likely to benefit from an LAI antipsychotic. Patients were randomly assigned to monthly intramuscular injections of HD (25-200 mg) or PP (39-234 mg) for up to 24 months.

A departmental initiative for clinical and translational research.

To encourage departmental research activities, the Department of Medicine of the Medical College of Georgia (MCG) introduced an internally funded Translational Research Program (TRP) in 2014. Patterned after the Vanderbilt Institute for Clinical and Translational Research, the program offers research studios for project guidance, research mentoring and the availability of limited financial support through research vouchers. Additional academic services include abstract reviewing, conducting research conferences, organizing departmental research programs for students, and offering courses in biostatistics.

Patterns and Correlates of Baseline Thiazide-Type Diuretic Prescription in the Systolic Blood Pressure Intervention Trial.

Thiazides and thiazide-type diuretics are recommended as first-line agents for the treatment of hypertension, but contemporary information on their use in clinical practice is lacking. We examined patterns and correlates of thiazide prescription in a cross-sectional analysis of baseline data from participants enrolled in the Systolic Blood Pressure Intervention Trial (SPRINT). We examined baseline prescription of thiazides in 7582 participants receiving at least 1 antihypertensive medication by subgroup, and used log-binomial regression to calculate adjusted prevalence ratios for thiazide prescription (versus no thiazide).

Barriers to outpatient stress testing follow-up for low-risk chest pain patients presenting to an ED chest pain unit.

Introduction: Outpatient stress testing (OST) after evaluation in the emergency department (ED) is an acceptable evaluation method for patients presenting to the ED with low-risk chest pain (CP). However, not all patients return for OST. Barriers to follow-up evaluation exist and are poorly understood.

Is Conduct of Research in Electroconvulsive Therapy Ethical?

Introduction: Controversy surrounding ECT creates skepticism about the ethics of conducting ECT research. This paper discusses the ethical conduct of clinical research and then focus on the ethics as applied to ECT.

Methods: PubMed was searched for articles related to the ethical conduct of research and that of ECT research published in English.

Immune suppressive mechanisms in the tumor microenvironment.

Effective immunotherapy, whether by checkpoint blockade or adoptive cell therapy, is limited in most patients by a key barrier: the immunosuppressive tumor microenvironment. Suppression of tumor-specific T cells is orchestrated by the activity of a variety of stromal myeloid and lymphoid cells. These often display inducible suppressive mechanisms that are triggered by the same anti-tumor inflammatory response that the immunotherapy intends to create.

Development and application of molecular biomarkers for characterizing Caribbean Yellow Band Disease in Orbicella faveolata.

Molecular stress responses associated with coral diseases represent an under-studied area of cnidarian transcriptome investigations. Caribbean Yellow Band Disease (CYBD) is considered a disease of Symbiodinium within the tissues of the coral host Orbicella faveolata. There is a paucity of diagnostic tools to assist in the early detection and characterization of coral diseases.

The genetic and environmental factors for keratoconus.

Keratoconus (KC) is the most common cornea ectatic disorder. It is characterized by a cone-shaped thin cornea leading to myopia, irregular astigmatism, and vision impairment. It affects all ethnic groups and both genders.

Case-control association between CCT-associated variants and keratoconus in a Saudi Arabian population.

Background: Keratoconus (KC) is the most common primary ectatic disease of the cornea and a major indication for corneal transplant. To date, limited KC-associated-risk loci have been identified. Association has recently been suggested between KC and 8 single nucleotide polymorphisms (SNPs) in the genomic regions of FNDC3B, COL4A3, MPDZ-NF1B, RXRA-COL5A1, LCN12-PTGDS, FOXO1, and BANP-ZNF469.

The incidental finding of a persistent left superior vena cava: implications for primary care providers-case and review.

Persistent left superior vena cava (PLSVC) is the most common thoracic venous anomaly and is a persistent congenital remnant of the vena caval system from early cardiac development. Patients with congenital anomalous venous return are at increased risk of developing various cardiac arrhythmias, due to derangement of embryologic conductive tissue during the early development of the heart. Previously this discovery was commonly made during the placement of pacemakers or defibrillators for the treatment of the arrhythmias, when the operator encountered difficulty with proper lead deployment.

Can α-lipoic acid mitigate progression of aging-related decline caused by oxidative stress?

Aging is progressively deteriorating physiological function that leads to increasing risks of illness and death. Increases in life expectancy and the aging of a large segment of the population have made age-related disability and morbidity increasingly important issues. Supplements such as α-lipoic acid may have antiaging effects by positively affecting oxidative stress, cognitive function, and cardiovascular function.

Relapse prevention after index electroconvulsive therapy in treatment-resistant depression.

Background: One-third of patients who suffer from depression are resistant to conventional treatments. An acute course of electroconvulsive therapy (ECT) can lead to remission of depressive symptoms in a substantial portion of the treatment-resistant patients. However, prevention of relapse with depressive symptoms after the index course of ECT can be challenging.

Electroconvulsive Therapy Malpractice: Verdict for the Defense.

Objectives: Malpractice cases involving electroconvulsive therapy (ECT) are rare. Even rarer are those malpractice cases alleging ECT-related brain damage. The few cases of ECT malpractice lawsuits are not described in the medical literature in detail.

Asenapine-induced restless legs syndrome: differentiation from akathisia.

Akathisia and restless legs syndrome (RLS) share some common clinical features and a common relationship with dopamine dysfunction. However, the underlying causes and appropriate treatments for akathisia and RLS are different. Herein we describe a case of RLS that was precipitated by a single dose of asenapine, which is an atypical antipsychotic, and dissect the features that support the contention that this was indeed a case of RLS and not akathisia.

A framework for describing health care delivery organizations and systems.

Describing, evaluating, and conducting research on the questions raised by comparative effectiveness research and characterizing care delivery organizations of all kinds, from independent individual provider units to large integrated health systems, has become imperative. Recognizing this challenge, the Delivery Systems Committee, a subgroup of the Agency for Healthcare Research and Quality's Effective Health Care Stakeholders Group, which represents a wide diversity of perspectives on health care, created a draft framework with domains and elements that may be useful in characterizing various sizes and types of care delivery organizations and may contribute to key outcomes of interest. The framework may serve as the door to further studies in areas in which clear definitions and descriptions are lacking.

Searching for the mechanism(s) of ECT's therapeutic effect.

The exact therapeutic mechanism of action of electroconvulsive therapy (ECT) remains unresolved. Numerous psychological theories from decades ago have been proven untrue. In the ensuing years, ECT has been proven to have numerous reproducible effects on brain chemistry, regional brain activity, electroencephalographic sleep stages, and neurogenesis.

IgG4-related leptomeningitis: a reversible cause of rapidly progressive cognitive decline.

Immunoglobulin G4-related diseases (IgG4-RD) are a newly recognized category of diseases. CNS involvement in IgG4-RD includes hypophysitis(1) and intracranial or spinal manifestations of hypertrophic pachymeningitis.(2,3) We present a unique case of rapid cognitive decline due to IgG4-related leptomeningitis.

Risks for gestational diabetes mellitus and pregnancy-induced hypertension are increased in polycystic ovary syndrome.

Objectives: To evaluate pregnancy outcomes and its determinants in women with polycystic ovary syndrome (PCOS).

Methods: Two-hundred and twenty pregnant PCOS and 594 healthy women were followed from early pregnancy. Incidences of gestational diabetes mellitus (GDM), pregnancy-induced hypertension (PIH), preterm birth, twinning, and fetal growth restriction (FGR) were determined.
