Introduction: Alopecia areata (AA) is an autoimmune disease that causes scalp, face, and/or body hair loss. Recently, oral treatments with kinases inhibition became the first approved therapies for severe AA. An understanding of the use and effectiveness of traditional therapies in real-world treatment settings is needed to guide integration of novel therapies into the treatment paradigm.

Unlabelled: Identification of risk factors for severe respiratory syncytial virus (RSV) disease in adults could facilitate their appropriate vaccine recommendations. We conducted a systematic literature review (last 10 years in PubMed/Embase) to identify quantitative estimates of risk factors for severe RSV infection outcomes in high-income countries. Severe outcomes from RSV infection included hospitalization, excess mortality, lower respiratory tract infection, or a composite measure: severe RSV, which included these outcomes and others, such as mechanical ventilation and extended hospital stay.

Article Synopsis
  • Respiratory syncytial virus (RSV) significantly impacts older adults and those with respiratory or cardiovascular issues, yet the incidence and prevalence data in these populations are inconsistent and variable.
  • A literature review identified 71 relevant studies from high-income Western countries since 2000, revealing common methodological flaws such as inappropriate case definitions, over-reliance on PCR testing, and a lack of consideration for seasonal variability.
  • The findings suggest that many studies likely underestimate RSV incidence in older adults, but the extent of this underestimation is uncertain, highlighting the need for better-designed research to accurately assess the virus's impact.

Introduction: Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infection (LRTI)-related hospitalizations in older adults. Without RSV-specific treatment for adults, testing is uncommon, leading to potential underestimation of RSV incidence in real-world data studies. This study aimed to quantify the frequency of RSV testing during LRTI-related hospitalizations of older adults to inform interpretation of incidence estimates.

Background: Early provisions of the Affordable Care Act (ACA) reduced financial barriers to preventive care, including routinely recommended vaccines; however, vaccination coverage remains suboptimal. This study examined characteristics of routine adult vaccinations and potential missed opportunities for vaccinations through the lens of healthcare resource utilization among adults in the ACA era.

Methods: This was a retrospective analysis of healthcare claims from the Truven Health MarketScan Commercial Claims and Encounters (CCAE), Medicare Supplemental (MS), and Multi-State Medicaid databases among adults aged 19 years or older.

Background: Octreotide has been used for decades in the United States (US) and Europe to treat patients with advanced neuroendocrine tumors (NETs). Lanreotide was approved in 2014 to improve progression-free survival (PFS) in patients with unresectable, well- or moderately-differentiated, locally advanced or metastatic gastroenteropancreatic NETs. Therefore, clinicians and patients may consider sequencing therapy from octreotide to lanreotide.

Introduction: Adult vaccination coverage rates in the US are well below national targets, leaving many adults at increased risk. Additionally, typical vaccination coverage calculations do not adequately approximate population immunity as they do not consider whether multidose vaccines were administered within the recommended schedules. As timely administration of each dose optimizes overall vaccine effectiveness, we sought to document adherence to and completion of the hepatitis A (HepA), hepatitis B (HepB), and combined hepatitis A and hepatitis B (HepA-HepB) multidose vaccine schedule in an insured adult population in the US.

Despite longstanding recommendations for routine vaccination against influenza; pneumococcal; tetanus, diphtheria, acellular pertussis (Tdap); and herpes zoster (HZ) among the United States general adult population, vaccine uptake remains low. Understanding factors that influence adult vaccination and coverage variability beyond the national level are important steps toward developing targeted strategies for increasing vaccination coverage. A retrospective analysis was conducted using data from the Behavioral Risk Factor Surveillance System (2011-2014).

Vaccination at age-appropriate intervals increases protection against morbidity and mortality; however, compliance rates among children remain low partly due to a complicated vaccination schedule. Use of combination vaccines reduces the number of injections per visit; however, there is limited evidence quantifying the effect of combination vaccines on vaccination rates. To examine how combination vaccines impact childhood completion (receipt of recommended doses) and compliance (receipt of age-appropriate vaccinations) rates, this study analyzed vaccination data from the 2012 National Immunization Survey (NIS), a nationally representative cross-sectional survey of caregivers of children aged 24 to 35 months in the United States.
