Latent class analysis of post-acute sequelae of SARS-CoV-2 infection.

Symptoms post-SARS-CoV-2 infection may persist for months and cause significant impairment and impact to quality of life. Acute symptoms of SARS-CoV-2 infection are well studied, yet data on clusters of symptoms over time, or post-acute sequelae of SARS-CoV-2 infection (PASC), are limited. We aim to characterize PASC phenotypes by identifying symptom clusters over a six-month period following infection in individuals vaccinated (boosted and not) and those unvaccinated.

Perceived barriers and enablers of a personal health record from the healthcare provider perspective.

Associations Between Patient Health Outcomes and Secure Message Content Exchanged Between Patients and Clinicians: Retrospective Cohort Study.

Background: The number of electronic messages securely exchanged between clinic staff and patients has risen dramatically over the last decade. A variety of studies explored whether the volume of messages sent by patients was associated with outcomes. None of these studies, however, examined whether message content itself was associated with outcomes.

Look Who's Talking: Application of a Theory-Based Taxonomy to Patient-Clinician E-mail Messages.

Patient-clinician communication between office visits may improve patient outcomes by increasing patients' information retention and offering opportunities for patient-centered communication. Secure electronic messaging offers one such communication modality, but evidence of associations between its use and patient outcomes is mixed. To date, no study has examined the relationship between message content and patient outcomes.

Psychopathology and HIV diagnosis among older adults in the United States: disparities by age, sex, and race/ethnicity.

In 2016, 17% of new HIV infections in the US were among adults aged 50 and older. Differences by age, sex, and race/ethnicity exist among older people living with HIV. Co-morbid mental health and substance use disorders (SUD) are also major challenges for this population.

The Worsening Profile of Alcoholic Hepatitis in the United States.
