The Emerging Role of Pharmacotherapy in Obstructive Sleep Apnea.

Obstructive sleep apnea (OSA) is a prevalent pathology with current modalities of treatment including continuous positive airway pressure (CPAP), surgery, weight loss, hypoglossal nerve stimulation, and pharmacotherapy. While CPAP is the current standard treatment for OSA, lack of tolerance and side effects necessitate alternative modalities of treatment. Various pharmacologic agents exist with mechanisms that may target OSA.

The Assessment of Infection Risk in Patients with Vitiligo Undergoing Dialysis for End-Stage Renal Disease: A Retrospective Cohort Study.

Vitiligo is an autoimmune condition that causes patchy skin depigmentation. Although the mechanism by which vitiligo induces immunocompromise is unclear, other related autoimmune diseases are known to predispose those affected to infection. Individuals with vitiligo exhibit epidermal barrier disruption, which could potentially increase their susceptibility to systemic infections; patients with renal disease also show a predisposition to infection.

Risk factors and mortality in dialysis patients with abdominal aortic aneurysm: A retrospective cohort study.

In the general population, abdominal aortic aneurysm (AAA) is synonymous with vascular disease and associated with increased mortality. Vascular disease is common in end-stage renal disease (ESRD) patients on dialysis, but there is limited information on AAA in this population. To address this issue, we queried the United States Renal Data System for risk factors associated with a diagnosis of AAA as well as the impact of AAA on ESRD patient survival.

Atopic Dermatitis and the Risk of Infection in End-Stage Renal Disease.

: Atopic dermatitis (AD), also known as eczema, is a common chronic inflammatory skin condition affecting 16.5 million adults in the United States. AD is characterized by an impaired epidermal barrier that can predispose individuals to infection.

Demographic and clinical risk factors for diagnosis of sleep disorders in ESRD patients.

Background: Sleep disturbances in patients with end-stage renal disease (ESRD) are common and more prevalent than in the general population. This study aims to assess the demographic and clinical risk factors for the diagnosis of sleep disorders in ESRD patients.

Methods: This study is a retrospective analysis of the United States Renal Data System (USRDS) to evaluate risk factors for the diagnosis of sleep disorders, including hypersomnolence, insomnia, restless leg syndrome (RLS), or obstructive or central sleep apnea (OSA/CSA).

Optical coherence tomography angiography and Humphrey visual field in patients with obstructive sleep apnea.

Study Objectives: To determine if obstructive sleep apnea syndrome (OSAS) predisposes patients to glaucoma and macular disease due to vascular compromise by evaluating retinal and optic nerve vasculature and function using optical coherence tomography angiography and Humphrey visual field testing, respectively.

Methods: In this prospective, observational, cross-sectional study 45 patients undergoing polysomnography ordered per standard of care were selected and stratified based on apnea-hypopnea index (AHI). Medical history, visual acuity testing, 24-2 Humphrey visual field, intraocular pressure measurement, and optical coherence tomography angiography studies of the macular and peripapillary retina were obtained.

Incidence and risk factors for mucormycosis in renal transplant patients.

Background: Renal transplant patients are at increased risk for mucormycosis. Diabetes, neutropenia, deferoxamine therapy, and immunosuppressive medications have been associated with increased risk of mucormycosis in studies of solid organ transplant recipients. To focus on renal transplant patients, the US Renal Data System (USRDS) was queried to determine the incidence and risk factors for mucormycosis.

Mystery in the mediastinum: Rare case of indolent primary thoracic amyloids.

A 53-year-old African American male smoker presented with epigastric pain, tarry stools, and laboratory results indicative of acute pancreatitis. Chest X-ray showed a right perihilar mass with pleural effusion. Computed tomography scan showed multiple large right paratracheal and hilar nodes with internal calcification.

Exosome secretome and mediated signaling in breast cancer patients with nontuberculous mycobacterial disease.

Bronchiectasis Nontuberculous mycobacterium (NTMnb) infection is an emerging health problem in breast cancer (BCa) patients. We measured sera exosome proteome in BCa-NTMnb subjects and controls by Mass Spectroscopy. Extracellular matrix protein 1 (ECM1) was detected exclusively in the circulating exosomes of 82% of the BCa-NTMnb cases.

Preliminary Results of Bedaquiline as Salvage Therapy for Patients With Nontuberculous Mycobacterial Lung Disease.

Background: Bedaquiline is an oral antimycobacterial agent belonging to a new class of drugs called diarylquinolines. It has low equivalent minimal inhibitory concentrations for Mycobacterium tuberculosis and nontuberculous mycobacterial (NTM) lung disease, especially Mycobacterium avium complex (MAC) and Mycobacterium abscessus (Mab). Bedaquiline appears to be effective for the treatment of multidrug-resistant TB but has not been tested clinically for NTM disease.

Exposures and idiopathic lung disease.

Of the idiopathic lung diseases, idiopathic pulmonary fibrosis (IPF) and sarcoidosis have been the focus of a growing number of epidemiological investigations on the risk of environmental and occupational exposures. To date, the consistency of epidemiological evidence is suggestive of a causal relationship between several environmental exposures and IPF, with the strongest evidence for cigarette smoking and metal dust. Current knowledge about pathogenesis provides further support for a causal link.

Is idiopathic pulmonary fibrosis an environmental disease?

Several sources of evidence, including investigations of pathogenesis and observational studies, support the hypothesis that environmental agents may have an etiologic role in idiopathic pulmonary fibrosis (IPF). Since 1990, six case-control studies have been conducted in three countries and have consistently demonstrated increased risk of IPF with exposures to a number of environmental and occupational agents. In a meta-analysis of these studies, six exposures were significantly associated with IPF (summary odds ratios [95% confidence intervals]), including ever smoking (1.
