Menstruation: An Important Indicator for Assessing Stroke Risk and Its Outcomes.

In recent years, stroke incidence in older adults has declined strikingly, but stroke in younger women has become more common. Abnormalities of menstruation, the shedding of the uterine lining at the beginning of each menstrual cycle, may offer clues about stroke risk in young and midlife women. Endometrial and structural uterine abnormalities are associated with anemia and may be associated with hypercoagulability, possibly increasing stroke risk.

Pericardial angiosarcoma is an extremely rare malignant tumor originating from the endothelial cells of blood vessels within the pericardium. We present a case of a 49-year-old male who presented with symptoms of pericardial effusion and was subsequently diagnosed with pericardial angiosarcoma. This case report highlights the diagnostic challenges and management options associated with this rare entity.

Beneficial Effects of Human Schwann Cell-Derived Exosomes in Mitigating Secondary Damage After Penetrating Ballistic-Like Brain Injury.

There is a growing body of evidence that the delivery of cell-derived exosomes normally involved in intracellular communication can reduce secondary injury mechanisms after brain and spinal cord injury and improve outcomes. Exosomes are nanometer-sized vesicles that are released by Schwann cells and may have neuroprotective effects by reducing post-traumatic inflammatory processes as well as promoting tissue healing and functional recovery. The purpose of this study was to evaluate the beneficial effects of human Schwann-cell exosomes (hSC-Exos) in a severe model of penetrating ballistic-like brain injury (PBBI) in rats and investigate effects on multiple outcomes.

Association of region-specific hippocampal reduction of neurogranin with inflammasome proteins in brains of Alzheimer's disease.

All individuals also underwent an ocular surface examination.

The effects of social support and support types on continuous positive airway pressure use after 1month of therapy among adults with obstructive sleep apnea.

Background: The relationship between perceived social support and continuous positive airway pressure remains understudied among individuals with obstructive sleep apnea. The aim of this prospective cohort study was to determine if baseline perceived social support and subtypes predict regular continuous positive airway pressure use after 1month of therapy.

Methods: Adults with obstructive sleep apnea initiating continuous positive airway pressure therapy were recruited from sleep clinics in New York City.

A Perspective on Hormonal Contraception Usage in Central Nervous System Injury.

Naturally occurring life stages in women are associated with changes in the milieu of endogenous ovarian hormones. Women of childbearing age may be exposed to exogenous ovarian hormone(s) because of their use of varying combinations of estrogen and progesterone hormones-containing oral contraceptives (OC; also known as "the pill"). If women have central nervous system (CNS) injury such as spinal cord injury (SCI) and traumatic brain injury (TBI) during their childbearing age, they are likely to retain their reproductive capabilities and may use OC.

Peripheral vestibular loss in noise-exposed firefighters.

Introduction: Occupational workers are increasingly aware of the risk of noise overexposure to the auditory system but lack awareness about potential risks to the vestibular system. The purpose of this study was to investigate changes in vestibular end organ function in a known at-risk noise-exposed population, firefighters compared to age- and sex-matched controls using electrophysiologic measures of cervical vestibular evoked myogenic potentials (cVEMP).

Methods: A cross-sectional observational study compared cVEMP response characteristics in 38 noise-exposed firefighters.

Discrimination Predicts Suboptimal Adherence to CPAP Treatment and Mediates Black-White Differences in Use.

Background: Although racial and ethnic differences in CPAP adherence for OSA are widely established, no studies have examined the influence of perceived racial discrimination on CPAP usage, to our knowledge.

Research Question: (1) Do Black adults with OSA report experiencing greater amounts of discrimination than non-Hispanic White adults? (2) Is discrimination associated with poorer CPAP adherence over time, independent of self-identified race? (3) Does discrimination mediate the relationship between self-identified Black race and CPAP usage?

Study Design And Methods: In this prospective study, Black and non-Hispanic White adults with OSA initiating CPAP were enrolled from two sleep centers and completed questionnaires including sociodemographics, perceived discrimination, daytime sleepiness, insomnia symptoms, and depressive symptoms. Perceived discrimination was measured using the Everyday Discrimination Scale (EDS).

A reliable and reproducible protocol for sound-evoked vestibular myogenic potentials in rattus norvegicus.

Introduction: Cervical vestibular evoked myogenic potentials (cVEMPs) provide an objective measure of the integrity of the sacculo-collic pathway leading to their widespread use as a clinical tool in the diagnostic vestibular test battery. Though the application of cVEMPs in preclinical models to assess vestibular function, as performed in relevant clinical populations, remains limited. The present study aimed to establish a rodent model of cVEMP with standardized methods and protocols, examine the neural basis of the responses, and characterize and validate important features for interpretation and assessment of vestibular function.

Co-morbid insomnia and sleep apnea (COMISA): recent research and future directions.

Purpose Of Review: Insomnia and obstructive sleep apnea have previously been viewed as completely independent conditions. However, there is now increasing recognition that insomnia and sleep apnea frequently co-occur. Co-morbid insomnia and sleep apnea (COMISA) is a highly prevalent condition that is associated with impairment of sleep, daytime function, mental health and physical health outcomes, and mortality risk.
