Purpose Of Review: To summarize the current treatment landscape of rheumatoid arthritis-associated interstitial lung disease (RA-ILD) in the context of the recent 2023 American College of Rheumatology/American College of Chest Physicians guideline for ILD treatment in systemic autoimmune rheumatic diseases.

Recent Findings: The guideline conditionally recommends mycophenolate, azathioprine, and rituximab for first-line RA-ILD therapy, with cyclophosphamide and short-term glucocorticoids as additional options. For RA-ILD progression after first line, mycophenolate, rituximab, nintedanib, tocilizumab, cyclophosphamide, and pirfenidone are conditionally recommended, while long-term glucocorticoids are conditionally recommended against.

Purpose Of Review: The purpose of this review is to outline considerations for treating older adults with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) as it relates to infection, comorbidities, cancer, and quality of life.

Recent Findings: The recent 2023 American College of Rheumatology/American College of Chest Physicians guideline conditionally recommended specific disease-modifying antirheumatic drugs (DMARDs), antifibrotics, and short-term glucocorticoids to treat RA-ILD. Since RA-ILD often affects older adults, we contextualize these pharmacologic options related to infection, gastrointestinal (GI) effects, cancer, cardiovascular disease, and quality of life.

Article Synopsis
  • The study investigates how cancer cells influence the fitness of surrounding tumor microenvironment (TME) cells through a mechanism involving a long non-coding RNA called Tu-Stroma, which alters the expression of Flower isoforms, impacting their growth advantage.
  • The expression of Flower Win isoforms in cancer cells enhances their dominance over TME cells that express Flower Lose isoforms, leading to reduced fitness in the TME.
  • Targeting Flower proteins with a humanized monoclonal antibody in mice has shown promising results, significantly reducing cancer growth and metastasis while improving survival rates and protecting organs from potential lesions.

Article Synopsis
  • The study explores how health care professionals and surrogates (family members) of patients with severe neurological injuries perceive the use of Cognitive Motor Dissociation (CMD) in making decisions about goals of care (GoC) and research involvement.
  • Findings show that 93% of participants would consider research participation if CMD indicated potential for recovery, compared to just 58% if CMD was negative.
  • It highlights that health care professionals are more likely to alter GoC based on CMD results compared to surrogates, with religious beliefs influencing how strongly participants might change their goals of care.

Article Synopsis
  • The study aimed to explore if disease-modifying antirheumatic drugs (DMARDs) increase the risk of developing interstitial lung disease (ILD) in patients with rheumatoid arthritis (RA) through a systematic review and meta-analysis of existing research.* -
  • From 3,612 studies, 40 were included, covering 486,465 RA patients and 3,928 cases of ILD; overall, no significant link was found between specific DMARDs and ILD in analyzed randomized controlled trials.* -
  • However, observational studies indicated that methotrexate (MTX) may reduce the odds of developing ILD, while a large trial comparing tofacitinib with another treatment showed no significant relationship

Article Synopsis
  • Natural language processing (NLP) is a part of AI aimed at helping computers understand text data, and while it's useful in critical care, it's not widely utilized in clinical research or quality improvement.
  • A scoping review was conducted, analyzing 87 studies from the past decade, primarily focused on using NLP to predict clinical outcomes like mortality and identify specific concepts in intensive care.
  • Most articles discussed the development of NLP algorithms, but very few covered real-world implementation, emphasizing the need for greater clinician awareness to enhance practical applications in healthcare settings.

Article Synopsis
  • About one-third of Portuguese patients with congenital hypogonadotropic hypogonadism (CHH) have a genetic cause linked to 10 different genes, with a small percentage showing oligogenic inheritance.
  • CHH leads to delayed puberty and infertility due to issues with hormones like GnRH, LH, and FSH.
  • In a study involving 81 patients and 263 controls, genetic screening helped identify pathogenic variants, but many variants classified as uncertain complicate the understanding of the disease causes.

Building on the initial accelerated pathway programs in the 1970s to increase workforce, nearly 30 schools have launched accelerated 3-year pathways (A3YP) during the past decade. The authors based on their educational roles, experiences, and scholarship with A3YP provide this perspective of the argument for A3YP and potential disadvantages for each group-students, schools, residencies, departments, and community. When schools consider innovations, they might consider A3YPs for multiple reasons; this perspective helps provide justification for the program and broadly considers return on investment (ROI).
