Previously, we reported increased risk of heavy-chain (HC) monoclonal gammopathy of undetermined significance (MGUS) among first-degree (1°) relatives of multiple myeloma (MM) or HC-MGUS probands. This study investigated whether there was comparable risk for light-chain (LC) MGUS among 911 relatives of the same HC-MGUS/MM probands versus a reference population of 21 463. Seventeen 1° relatives had LC-MGUS (adjusted prevalence = 1·7%, 95% CI = 0·9–2·6%). There was increased risk of LC-MGUS in relatives of MM probands (RR = 3·4, 95% CI = 2·0–5·5). We saw no increased risk in relatives of HC-MGUS probands. We conclude that the prevalence of LC-MGUS is significantly higher among 1° relatives of MM probands compared to the reference population.

Importance: Exposure to fine particulate matter air pollution (PM2.5) may increase risk for dementia. It is unknown whether this association is mediated by dementia-related neuropathologic change found at autopsy.

Importance: Youth living with type 1 diabetes (T1D) are increasingly choosing automated insulin delivery (AID) systems to manage their blood glucose. Few systematic reviews meta-analyzing results from randomized clinical trials (RCTs) are available to guide decision-making.
Objective: To study the association of prolonged AID system use in an outpatient setting with measures of glucose management and quality of life in youth with T1D.

Background: Few data are available on the impact of primary sclerosing cholangitis (PSC) on inflammatory bowel disease (IBD).
Objective: We conducted a retrospective study using TriNetX to compare the outcomes of patients with IBD and those with concomitant IBD and PSC.
Methods: All patients with a confirmed diagnosis of Crohn's disease (CD), ulcerative colitis (UC), or indeterminate colitis with or without PSC were eligible.
