Performance of Impulse Oscillometry in Identifying Restrictive Lung Defects in a Veteran Cohort.

Background: Impulse oscillometry (IOs) is a technique used to evaluate lung function that uses sound waves imposed over tidal breathing to characterize the airways and lung parenchyma. IOs has been particularly useful in the identification of obstructive lung defects. The present analysis seeks to explore the use of IOs in the identification of restrictive lung physiology among a group of Gulf War I veterans exposed to depleted uranium (DU).

Respiratory Health Associated With Systemic Metal Exposure in Post-9/11 Veterans in the Department of Veterans Affairs Toxic Embedded Fragment Registry.

Objective: Adverse respiratory outcomes in post-9/11 veterans with elevated urinary metal measures and enrolled in the VA's Toxic Embedded Fragment registry were compared to those without elevated urinary metals.

Methods: Veterans completed questionnaires, underwent pulmonary physiology tests (pulmonary function and oscillometry), and provided urine samples for analysis of 13 metals. Respiratory symptoms, diagnoses, and physiology measures were compared in veterans with ≥1 urine metal elevation to those without metal elevations, adjusted for covariates, including smoking.

A case of naltrexone-induced acute eosinophilic pneumonia.

Acute eosinophilic pneumonia (AEP) is a rare cause of acute respiratory failure. Clinical presentations can range from dyspnoea, fever and cough, to rapidly progressive and potentially fulminant respiratory failure. While its exact cause is often unknown, associations with inhalational injuries and exposures to new medications have been described.

Contemporary Systemic Therapy Intensification for Prostate Cancer: A Review for General Practitioners in Oncology.

Prostate cancer accounts for a significant proportion of cancer diagnoses in Canadian men. Over the past decade, the therapeutic landscape for the management of metastatic prostate cancer has undergone rapid changes. Novel strategies use hormonal agents, chemotherapy, homologous recombination repair inhibitors, and radioligand therapy or combination strategies in addition to androgen deprivation therapy.

Metaphysical indeterminacy in Everettian quantum mechanics.

The question of whether Everettian quantum mechanics (EQM) justifies the existence of metaphysical indeterminacy has recently come to the fore. Metaphysical indeterminacy has been argued to emerge from three sources: coherent superpositions, the indefinite number of branches in the quantum multiverse and the nature of these branches. This paper reviews the evidence and concludes that those arguments don't rely on EQM alone and rest on metaphysical auxiliary assumptions that transcend the physics of EQM.

Prophylactic epinephrine attenuates severe bleeding in lung transplantation patients undergoing transbronchial lung biopsy: Results of the PROPHET randomized trial.

Background: Severe hemorrhage is an uncommon yet potentially life-threatening complication of transbronchial lung biopsy. Lung transplantation recipients undergo multiple bronchoscopies with biopsy and are considered to be at an increased risk for bleeding from transbronchial biopsy, independent of traditional risk factors. We aimed to evaluate the efficacy and safety of endobronchial administration of prophylactic topical epinephrine in attenuating transbronchial biopsy-related hemorrhage in lung transplant recipients.

Economic Impact of Insufficient and Disturbed Sleep in the Workplace.

Objective: Insufficient and disturbed sleep are associated with significant morbidity among working-age adults. Poor sleep results in negative health outcomes and increases economic costs to employers. The current systematic review surveyed the peer-reviewed scientific literature and aggregated scientific evidence of sleep-related economic burdens borne by employers.

Self-reported respiratory outcomes associated with blast exposure in post 9/11 veterans.

Background: Blast lung overpressure has received interest as a cause of chronic respiratory disease in Service members who deployed in support of U.S. military operations in Southwest Asia and Afghanistan since 2001.

The influence of social norms varies with "others" groups: Evidence from COVID-19 vaccination intentions.

The theory that health behaviors spread through social groups implies that efforts to control COVID-19 through vaccination will succeed if people believe that others in their groups are getting vaccinated. But "others" can refer to many groups, including one's family, neighbors, fellow city or state dwellers, or copartisans. One challenge to examining these understudied distinctions is that many factors may confound observed relationships between perceived social norms (what people believe others do) and intended behaviors (what people themselves will do), as there are plausible common causes for both.

Images: polysomnographic findings of nystagmus caused by a midbrain hemorrhagic stroke.

Unlabelled: Brainstem strokes can present with an array of ophthalmologic findings depending on the location of the lesion. Eye movements are recorded on electrooculogram during polysomnography for sleep staging. We present the case of a patient with a dorsal midbrain hemorrhagic stroke and nystagmus with distinct findings on the electrooculogram during polysomnography.

December Is Coming: A Time Trend Analysis of Monthly Variation in Adult Elective Anesthesia Caseload across Florida and Texas Locations of a Large Multistate Practice.

Background: Anesthesia staffing models rely on predictable surgical case volumes. Previous studies have found no relationship between month of the year and surgical volume. However, seasonal events and greater use of high-deductible health insurance plans may cause U.

Surveillance of Depleted Uranium-exposed Gulf War Veterans: More Evidence for Bone Effects.

Gulf War I veterans who were victims of depleted uranium (DU) "friendly-fire" incidents have undergone longitudinal health surveillance since 1994. During the spring of 2019, 36 members of the cohort were evaluated with a monitoring protocol including exposure assessment for total and isotopic uranium concentrations in urine and a comprehensive review of health outcomes, including measures of bone metabolism and bone mineral density (BMD) determination. Elevated urine U concentrations were observed in cohort members with retained depleted uranium (DU) shrapnel fragments.

Trends in Moral Injury, Distress, and Resilience Factors among Healthcare Workers at the Beginning of the COVID-19 Pandemic.

The coronavirus severe acute respiratory syndrome (COVID-19) pandemic has placed increased stress on healthcare workers (HCWs). While anxiety and post-traumatic stress have been evaluated in HCWs during previous pandemics, moral injury, a construct historically evaluated in military populations, has not. We hypothesized that the experience of moral injury and psychiatric distress among HCWs would increase over time during the pandemic and vary with resiliency factors.

Complex obstructive lung disease - A diagnostic and management conundrum.

Rheumatoid arthritis (RA) is a common autoimmune disease most well-known for its inflammatory, destructive polyarthropathy. Extraarticular manifestations of the disease may involve the respiratory system, including interstitial lung disease, pleural disease, pulmonary vascular abnormalities, and airways disease. Smoking is highly prevalent in the RA population, and may even have a synergistic effect in disease development and progression.

Perceptions of Public Health Priorities and Accountability Among US Mayors.

Objective: Mayors have considerable and often direct influence over health policy in their cities, yet little is known about mayors' general perceptions of current public health challenges. The objective of this study was to assess perceptions, attitudes, and priorities related to public health among US mayors.

Methods: We collected survey data from a nationally representative sample of US mayors (N = 110) in 2018 and matched survey responses with city-level health surveillance data.

Longitudinal Evaluation of Lung Function in Gulf War I Veterans Exposed to Depleted Uranium.

Objective: Gulf War I (GWI) Veterans exposed to depleted uranium (DU) have undergone biennial surveillance to assess for DU-related health effects. No DU-specific respiratory effects have been observed cross-sectionally, but longitudinal lung function decline has not been assessed.

Methods: A dynamic cohort of 71 Veterans underwent spirometry testing between 1999 and 2019.

Factors Affecting Patient Satisfaction With Their Anesthesiologist: An Analysis of 51,676 Surveys From a Large Multihospital Practice.

Background: An increasing focus of health care quality is the assessment of patient-reported outcomes, including satisfaction. Because anesthesia care occurs in the context of perioperative surgical care, direct associations between anesthetic management and patient experience may be difficult to identify. We analyzed anesthesia-specific patient satisfaction survey data from a large private practice group to identify patient, procedure, and anesthetic-specific predictors of patient satisfaction with their anesthesiologist, measured via responses to a validated patient satisfaction survey instrument.

Posttraumatic Stress Disorder in Older Adults: A Conceptual Review.

: We provide a review of the literature on posttraumatic stress disorder (PTSD) in older adults, focusing largely on older U.S. military veterans in two primary areas: 1) assessment and diagnosis and 2) non-pharmacological treatment of PTSD in late life.

Efficacy of Nivolumab and Pembrolizumab in Patients With Advanced Non-Small-Cell Lung Cancer Needing Treatment Interruption Because of Adverse Events: A Retrospective Multicenter Analysis.

Introduction: The programmed death 1 antibodies (PD-1 Ab) nivolumab and pembrolizumab improve overall survival (OS) in advanced non-small-cell lung cancer (NSCLC). We evaluated the correlation between immune-related adverse events (irAE) and treatment interruption due to irAE on clinical efficacy of PD-1 Ab in advanced NSCLC.

Patients And Methods: Advanced NSCLC patients treated with PD-1 Ab between June 2015 to November 2017 at BC Cancer were identified.
