Clonal haematopoiesis across the age spectrum of vasculitis patients with Takayasu's arteritis, ANCA-associated vasculitis and giant cell arteritis.

Objectives: Ageing and inflammation are associated with clonal haematopoiesis (CH), the emergence of somatic mutations in haematopoietic cells. This study details CH in patients with systemic vasculitis in association with clinical, haematological and immunological parameters.

Methods: Patients with three forms of vasculitis were screened for CH in peripheral blood by error-corrected sequencing.

Parental Preconception Adversity and Offspring Mental Health in African Americans and Native Americans in the United States: A Systematic Review.

This systematic review examines the impact of parental preconception adversity on offspring mental health among African Americans (AAs) and Native Americans (NAs), two populations that have experienced historical trauma and currently experience ethnic/racial mental health disparities in the United States. PsycINFO, PubMed, CINAHL, Scopus, and Web of Science were searched for studies that included at least two generations of AAs or NAs from the same family, measured parental preconception adversity and their offspring's mental health, and examined the association between these variables. Over 3,200 articles were screened, and 18 articles representing 13 unique studies were included in this review.

Somatic mutations in rheumatological diseases: VEXAS syndrome and beyond.

Discovery of the VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome demonstrates that somatic mutations in haematological precursor cells can cause adult-onset, complex inflammatory disease. Unlike germline mutations, somatic mutations occur throughout the lifespan, are restricted to specific tissue types, and may play a causal role in non-heritable rheumatological diseases, especially conditions that start in later life. Improvements in sequencing technology have enabled researchers and clinicians to detect somatic mutations in various tissue types, especially blood.

Effect of a Nurse-Led Community Health Worker Intervention on Latent Tuberculosis Medication Completion Among Homeless Adults.

Background: Tuberculosis (TB) disproportionately affects marginalized and impoverished homeless adults. Although active TB can be prevented by treating latent TB infection (LTBI), individual factors, such as high prevalence of depression and anxiety, drug and alcohol use, and unstable housing, lead to poor LTBI treatment adherence and completion among homeless adults.

Objectives: We hypothesized that the delivery of a tailored nurse-led, community health worker (RN/CHW) program across the LTBI continuum of care (e.

Drug-Mimicking Nanofibrous Peptide Hydrogel for Inhibition of Inducible Nitric Oxide Synthase.

In this work, we develop a drug-mimicking nanofibrous peptide hydrogel that shows long-term bioactivity comparable to a small-molecule inhibitor of inducible nitric oxide synthase (iNOS). The iNOS inhibitor, -(1-iminoethyl)-l-lysine (l-NIL), is a positively charged amino acid whose structure could be readily integrated into the framework of a positively charged multidomain peptide (MDP) through the modification of lysine side chains. This new l-NIL-MDP maintains the self-assembling properties of the base peptide, forming -sheet nanofibers, which entangle into a thixotropic hydrogel.

Nucleophosmin mutations confer an independent favorable prognostic impact in 869 pediatric patients with acute myeloid leukemia.

Studies on the clinical significance of Nucleophosmin (NPM1) mutations in pediatric AML in a large cohort are lacking. Moreover, the prognosis of patients with co-occurring NPM1 and FLT3/ITD mutations is controversial. Here, we analyzed the impact of NPM1 mutations on prognoses of 869 pediatric AML patients from the TAGET dataset.
