Epigenome-wide association study of prostate cancer in African American men identified differentially methylated genes.

Introduction: Men with African ancestry have the highest incidence and mortality rates of prostate cancer (PCa) worldwide.

Methods: This study aimed to identify differentially methylated genes between tumor vs. adjacent normal and aggressive vs.

Sex-specific effects of chronic stress prior to cocaine exposure on cue- vs drug-induced relapse after prolonged abstinence.

The comorbidity between cocaine use disorder (CUD) and trauma/stressor-related disorders suggests a connection between neurophysiological changes induced by stress and those that lead to cocaine use. Due to the unexpected and sometimes uncontrollable nature and timing of stressful life events, their capacity to induce drug use poses a significant challenge for the administration of cocaine relapse therapy. This study aims to investigate the impact of chronic stress applied prior to cocaine acquisition on the development of cocaine-seeking behavior after different periods of drug abstinence in male and female rats.

Neuroimaging of Vermiform Giant Arachnoid Granulations in Children.

Arachnoid granulations (AGs) are generally benign structures within the subarachnoid space that extend into the dural sinuses and calvarial bone. They can present in a variety of sizes but are termed 'giant' arachnoid granulations (GAGs) when they are larger than 1 cm in diameter or take up a significant portion of the dural sinus' lumen. Vermiform giant arachnoid granulations are a specific type of GAG that are known for their worm-like appearance.

Clinical Features and Therapeutic Outcomes Comparing Primary Mediastinal Large B-cell Lymphoma to Mediastinal Hodgkin Disease.

Currently, there is limited data available comparing Primary Mediastinal Large B-cell Lymphoma (PMBL) and mediastinal Hodgkin disease, nodular sclerosis type (HDNS). This is a retrospective cohort study that compares the clinical features, histology through immunohistochemistry (IHC) and treatment outcomes of 19 cases of PMBL and 39 cases of HDNS diagnosed over 13 years at a single institution in San Juan, PR. Superior Vena Cava syndrome (SVCS) and elevated Lactate Dehydrogenase (LDH) levels were more frequently seen in the PMBL cohort.

Unraveling the association between major depressive disorder and senescent biomarkers in immune cells of older adults: a single-cell phenotypic analysis.

Little is known about the prevalence of cellular senescence among immune cells (i.e., immune cells expressing senescence markers, iSCs) nor is there a gold-standard to efficiently measure iSCs.

GABA system as the cause and effect in early development.

GABA is the primary inhibitory neurotransmitter in the adult brain and through its actions on GABARs, it protects against excitotoxicity and seizure activity, ensures temporal fidelity of neurotransmission, and regulates concerted rhythmic activity of neuronal populations. In the developing brain, the development of GABAergic neurons precedes that of glutamatergic neurons and the GABA system serves as a guide and framework for the development of other brain systems. Despite this early start, the maturation of the GABA system also continues well into the early postnatal period.

Analysis of a Medication Safety Intervention in the Pediatric Emergency Department.

Importance: Strategies to reduce medication dosing errors are crucial for improving outcomes. The Medication Education for Dosing Safety (MEDS) intervention, consisting of a simplified handout, dosing syringe, dose demonstration and teach-back, was shown to be effective in the emergency department (ED), but optimal intervention strategies to move it into clinical practice remain to be described.

Objective: To describe implementation of MEDS in routine clinical practice and associated outcomes.

Laser-Assisted Prostaglandin Analogs in the Treatment of Hypopigmented Scars: A Systematic Review.

Background: Hypopigmented scars are challenging to treat due to a lack of effective treatments and often transient results. Recent reports suggest that prostaglandin analog-induced hyperpigmentation may have favorable dermatological applications.

Objective: Analyze previous studies involving the use of prostaglandin analogs in the treatment of hypopigmented scars.

Systemic Disease Associations in a Cohort of Hispanic Patients with Scleritis.

(1) Purpose: A patient with scleritis may have an associated systemic disease, which is often autoimmunological and seldom infectious in origin. The data regarding such associations in Hispanic populations are scarce. Therefore, we evaluated the clinical characteristics and systemic-disease associations of a cohort of Hispanic patients with scleritis.

Association between DNA repair capacity and body mass index in women.

Objective: Examine whether DNA repair capacity (DRC) levels are associated with body mass index (BMI) in adult women.

Design And Participants: A nested study composed of 539 women without breast cancer (BC) from a case-control BC study in addition to 104 that were recruited later for a total of 643.

Measurements: DRC levels were measured in lymphocytes using a host-cell reactivation assay with a luciferase reporter gene damaged by UVC.

Interventions associated with brown adipose tissue activation and the impact on energy expenditure and weight loss: A systematic review.

Background: Brown adipose tissue (BAT) plays a role in modulating energy expenditure. People with obesity have been shown to have reduced activation of BAT. Agents such as β-agonists, capsinoids, thyroid hormone, sildenafil, caffeine, or cold exposure may lead to activation of BAT in humans, potentially modulating metabolism to promote weight loss.

Dermatologic manifestations in patients with the Hermansky-Pudlak syndrome types 1 and 3.

Background: The Hermansky-Pudlak syndrome (HPS) is a genetically heterogeneous group of diseases characterized by oculocutaneous albinism, bleeding diathesis, and systemic complications. It is the most common genetic disorder in Puerto Rico. These patients are at a significant risk of developing a variety of skin complications and little is known about the prevalence of dermatologic diagnoses in this population.

Racial/ethnic disparities in gastric cancer: A 15-year population-based analysis.

Background And Aims: Disparities in gastric cancer incidence and mortality have been reported among ethnic/racial groups. While gastric cancer is not common in the U.S.

Injury Characteristics, Outcomes, and Health Care Services Use Associated With Nonfatal Injuries Sustained in Mass Shootings in the US, 2012-2019.

Importance: Civilian public mass shootings (CPMSs) in the US result in substantial injuries. However, the types and consequences of these injuries have not been systematically described.

Objective: To describe the injury characteristics, outcomes, and health care burden associated with nonfatal injuries sustained during CPMSs and to better understand the consequences to patients, hospitals, and society at large.

An Unusual Case of Deep Localized Scleroderma in a Patient with Chronic Kidney Disease.

Localized scleroderma (LS) is a rare fibrosing disorder of skin and underlying tissues. Although it can affect all races, it has a higher prevalence in whites. Deep LS is the least common among seven LS variants, representing less than 5% of cases, and typically affects areas of pressure such as the hips and waist.
