Electronic cigarette (e-cigarette) use, or vaping, is gaining widespread popularity among adults aged 18–35. Vaping is commercially promoted as a safer alternative to traditional cigarette smoking. Previous studies have reported a close relationship between conventional cigarette smoking and acute eosinophilic pneumonia (AEP), but only one case report to date associates vaping with AEP in a male patient. We present the first case of AEP involving a young female after use of e-cigarettes. Clinicians should consider AEP when evaluating young patients with hypoxic respiratory failure and a recent history of e-cigarette use. This case highlights the need for more research into the relationship between e-cigarettes and AEP.

The IMPROVE BRS calculated at admission predicts major bleeding in medical inpatients. This model may help assess the relative risks of bleeding and VTE before chemoprophylaxis is administered.

Background We evaluated the clinical outcomes, functional burden, and complications one month after COVID-19 infection in a prospective United States Military Health System (MHS) cohort of active duty, retiree, and dependent populations using serial patient-reported outcome surveys and electronic medical record (EMR) review. Methods MHS beneficiaries presenting at nine sites across the United States with a positive SARS-CoV-2 test, a COVID-19 like illness, or a high-risk SARS-CoV-2 exposure were eligible for enrollment. Medical history and clinical outcomes were collected through structured interviews and ICD-based EMR review. Risk factors associated with hospitalization were determined by multivariate logistic regression. Results A total of 1,202 participants were enrolled. There were 1,070 laboratory confirmed SARS-CoV-2 cases and 132 SARS-CoV-2 negative participants. In the first month post-symptom onset among the SARS-CoV-2 positive cases, there were 214 hospitalizations, 79% requiring oxygen, 22 ICU admissions, and 9 deaths. Risk factors for COVID-19 associated hospitalization included race (increased for Asian, Black, and Hispanic compared to non-Hispanic White), age (age 45-64 and 65+ compared to <45), and obesity (BMI>=30 compared to BMI<30). Over 2% of survey respondents reported the need for supplemental oxygen and 31% had not returned to normal daily activities at one-month post-symptom onset. Conclusions Older age, reporting Asian, Black or Hispanic race/ethnicity, and obesity are associated with SARS-CoV-2 hospitalization. A proportion of acute SARS-CoV-2 infections require long-term oxygen therapy; the impact of SARS-CoV-2 infection on short-term functional status was substantial. A significant number of MHS beneficiaries had not yet returned to normal activities by one month.

Background The FLU-PRO Plus is a patient-reported outcome data collection instrument assessing symptoms of viral respiratory tract infections across eight body systems. This study evaluated the measurement properties of FLU-PRO Plus in a study enrolling individuals with COVID-19. Methods Data from a prospective cohort study (EPICC) in US Military Health System (MHS) beneficiaries evaluated for COVID-19 was utilized. Adults with symptomatic SARS-CoV-2 infection with FLU-PRO Plus survey information within one week of symptom onset were included. Reliability of FLU-PRO Plus was estimated using intraclass correlation coefficients (ICC; 2 days reproducibility). Known-groups validity was assessed using patient global assessments (PGA) of disease severity. Patient report of return to usual health was used to assess responsiveness (day 1-6/7). Results 226 SARS-CoV-2 positive participants were included in the analysis. Reliability among those who reported no change in their symptoms from one day to the next was high for most domains (ICC range 0.68-0.94 for day 1 to day 2). Construct validity was demonstrated by moderate to high correlation between the PGA rating of disease severity and domain and total scores (e.g., total scores correlation: 0.69 (influenza-like illness severity), 0.69 (interference in daily activities), and -0.58 (physical health)). In addition, FLU-PRO Plus demonstrated good known-groups validity, with increasing domain and total scores observed with increasing severity ratings. Conclusions FLU-PRO Plus performs well in measuring signs and symptoms in SARS-CoV-2 infection with excellent construct validity, known-groups validity, and responsiveness to change. Standardized data collection instruments facilitate meta-analyses, vaccine effectiveness studies, and other COVID-19 research activities.
