Spontaneous globe rupture from an intraocular melanotic schwannoma.

Introduction: Melanotic schwannoma (MS) is a rare neoplasm composed of Schwann cells with melanosomes in various maturation stages. While MS is typically observed in spinal nerve roots or peripheral nerves, their involvement in intraocular structures is uncommon. Here, we present a case of spontaneous globe rupture as the presenting feature of intraocular extension of a MS.

Metastasis development in non-muscle-invasive bladder cancer.

Non-muscle-invasive bladder cancer (NMIBC) is the most common type of bladder cancer presentation and is characterized by a varying probability of recurrence and progression. Sporadically, patients with NMIBC might also develop tumour metastases without any pathological evidence of muscle-invasive disease within the bladder, a condition known as metastatic NMIBC. In the published literature, this phenomenon is limited to several case reports and small reviews, with few data regarding the possible aetiologies.

Differing conceptual maps of skills for implementing evidence-based interventions held by community-based organization practitioners and academics: A multidimensional scaling comparison.

Community-based organizations (CBOs) are critical for delivering evidence-based interventions (EBIs) to address cancer inequities. However, a lack of consensus on the core skills needed for this work often hinders capacity-building strategies to support EBI implementation. The disconnect is partly due to differing views of EBIs and related skills held by those typically receiving versus developing capacity-building interventions (here, practitioners and academics, respectively).

Improved Outcomes of Liver Transplantation in Patients With Hepatitis C, Following the Introduction of Innovative Antiviral Therapies.

Background: The treatment landscape for hepatitis C virus (HCV) underwent a significant shift with the introduction of direct-acting antiviral (DAA) medications in late 2013. This study aimed to evaluate the impact of DAAs on liver transplantation outcomes, examining both the benefits and any potential drawbacks associated with their use.

Large-scale single-nuclei profiling identifies role for ATRNL1 in atrial fibrillation.

Atrial fibrillation (AF) is the most common sustained arrhythmia in humans, yet the molecular basis of AF remains incompletely understood. To determine the cell type-specific transcriptional changes underlying AF, we perform single-nucleus RNA-seq (snRNA-seq) on left atrial (LA) samples from patients with AF and controls. From more than 175,000 nuclei we find that only cardiomyocytes (CMs) and macrophages (MΦs) have a significant number of differentially expressed genes in patients with AF.

Cardiovascular outcomes among giant cell myocarditis compared with cardiac sarcoidosis: A propensity score-matched analysis.

Background: Giant cell myocarditis (GCM) and cardiac sarcoidosis (CS) are rare inflammatory diseases of the myocardium with poor prognosis. Cardiovascular disease outcomes among both diseases have not been well studied with limited literature.

Advancing patient-centered metrics for heart transplantation: The role of days alive and outside the hospital.

Background: Heart transplantation (HT) survival and waitlist times are established outcome metrics. Patient-centered HT outcomes are insufficiently characterized. This study evaluates the role of days alive and outside the hospital (DAOH) as a candidate patient-centered HT performance measure.

Biomechanical Comparison of Spacer Pin Fixation to Two Established Methods of Tibial Tuberosity Transposition Stabilization in Dogs.

Objective:  The aim of this cadaveric study was to compare the biomechanical outcomes of three methods of stabilization for tibial tuberosity transposition to treat medial patellar luxation: a complete osteotomy with a two-pin and tension band wire (TBW) fixation (TBW group), a partial osteotomy with a two-pin fixation (2 Pin group), and a partial osteotomy with a spacer pin fixation (Spacer Pin group).

Study Design:  Thirty medium to large-sized canine cadaveric tibiae were dissected and randomly assigned to one of three groups: TBW, 2 Pin, and Spacer Pin groups. The patellar ligaments were loaded in tension until ultimate failure.

Innumerable Culture-Negative Intracranial Abscesses in an Immunocompetent Young Male Diagnosed by 16s rRNA Gene Sequencing.

Here, we present a case of a healthy young man with an initial presentation concerning for infectious encephalitis later found on neuroimaging to have extensive intracranial lesions. Pathological analysis of these lesions was consistent with a bacterial intraparenchymal abscess; however, cultures were negative for a causative organism. Results of gene sequencing from an abscess sample were consistent with infection.

Eradication of Persister Cells by Eravacycline.

is a leading bacterial pathogen that causes persistent infections. One major reason that antibiotics fail to clear such infections is the presence of a dormant subpopulation called persister cells. To eradicate persister cells, it is important to change drug development from traditional strategies that focus on growth inhibition to the search for new leads that can kill dormant cells.

Treatment of brain metastases from non-small cell lung cancer: preclinical, clinical, and translational research.

Lung cancer is the second most common type of cancer and is the leading cause of cancer-related deaths in the United States. Approximately 10-40% of patients with solid tumors develop brain metastases, with non-small cell lung cancer accounting for approximately 50% of all cases of patients with brain metastases. Many management options are available which can include surgery, radiation, and systemic therapy.

Increased Risk of Hypoglycemia Following Roux-en-Y Gastric Bypass Surgery in Patients Without Diabetes: a Propensity Score-Matched Analysis.

Background: Roux-en-Y gastric bypass (RYGB) surgery is an effective treatment for obesity. However, the incidence and long-term risk of hypoglycemia after surgery in patients without diabetes remains unclear. This study aimed to investigate the prevalence of hypoglycemia following RYGB surgery in patients with obesity and without diabetes.

Healthcare resource utilization and costs associated with first versus subsequent use of cariprazine for bipolar I disorder.

Aims: To evaluate the healthcare resource utilization (HRU) and costs of patients who initiated cariprazine as their first versus subsequent atypical antipsychotic (AA) following a bipolar I disorder (BP-I) diagnosis.

Methods: Adults with a BP-I diagnosis (first claim = index), commercial, Medicare Supplemental, or Medicaid insurance, and ≥1 outpatient cariprazine dispensing were identified from Merative MarketScan database. Cohorts included patients who initiated cariprazine as either their first or subsequent AA after initial BP-I diagnosis.

Clinical and Biochemical Outcomes in Transgender Individuals Undergoing Hormone Therapy: Protocol for a Systematic Review.

Background: Monitoring of various clinical outcomes and parameters, such as lipid levels, is recommended in transgender individuals undergoing hormone therapies. However, comprehensive data to inform these recommendations is scarce.

Objective: This study aims to conduct a systematic review and meta-analysis to synthesize evidence from existing literature on the effect of exogenous hormone therapy on clinical and biochemical outcomes for transgender adolescents and adults.

QRS prolongation is associated with associated with adverse cardiac remodeling in hypertrophic cardiomyopathy.

Background: Signal-averaged electrocardiogram (SAECG) records myocardial depolarization, and can detect inhomogeneous/slow conduction in fibrotic myocardium, which promotes reentrant ventricular arrhythmias (VAs). Hypertrophic cardiomyopathy (HCM) is associated with a high prevalence of cardiac fibrosis and VAs, but abnormal SAECG has low predictive power for VAs. We hypothesized that HCM-specific structural/electrical remodeling underlies this result.

Results: NET scales had good scale and test-retest reliability.

Analyses of Off-Target Effects on Cardiac and Skeletal Muscles by Berberine, a Drug Used to Treat Cancers and Induce Weight Loss.

Previous reports from our laboratory describing the formation of myofibrils in cultured embryonic cardiac and skeletal muscle cells have proposed that myofibrillogenesis occurs in three steps of increasing protein organization: beginning with premyofibrils, followed by nascent myofibrils, and ending in mature myofibrils. Inhibitors of the ubiquitin proteasome system (UPS) prevented nascent myofibrils from progressing directly to mature myofibrils in cultured cardiac and skeletal muscle cells, supporting a three-step model of assembly in which some of the proteins in nascent myofibrils are proteolyzed to allow the assembly of mature myofibrils. Application of UPS inhibitors on cultured muscle cells suggests possible explanations for the off-target cardiac and skeletal muscle adverse effects of UPS drugs, which are used on cancer patients.

The future of hypertension pharmacotherapy: Ongoing and future clinical trials for hypertension.

Hypertension is among the most prevalent diagnoses across the world and increases the risk of many serious health problems, such as stroke, heart disease, and kidney disease. Pharmacological approaches to treat hypertension are often required and reduce blood pressure through mechanisms such as vasodilation, inhibition of the renin-angiotensin-aldosterone pathway, and increased urine output to reduce blood volume, among other mechanisms. Further research is ongoing to find novel pathways and mechanisms to treat hypertension, which we summarize in this review.
