Alemtuzumab and thrombotic thrombocytopenic purpura: Analysis of an international surveillance database and systematic literature review.

Objectives: Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy associated with severe deficiency in ADAMTS13. ADAMTS13 deficiency may be secondary to absent or dysfunctional protein production due to mutations in the ADAMTS13 gene (congenital TTP) or autoantibody-mediated clearance and/or inhibition (immune-mediated TTP). This autoimmunity may, albeit rarely, occur secondary to certain medications (eg, ticlopidine).

Coagulation abnormalities following brown recluse spider (Loxosceles reclusa) envenomation: A description of 2 cases and review of the literature.

Objective: Hemostatic abnormalities, including disseminated intravascular coagulation (DIC), are often cited as a common finding in patients following Loxosceles spider envenomation (ie, loxoscelism). The prevalence and severity of coagulopathy, however, particularly following L reclusa (ie, brown recluse) envenomation, is not well described. This study aimed to characterize coagulation laboratory parameters and coagulopathy in patients following L reclusa envenomation.

Screening for Osteoporosis to Prevent Fractures: A Systematic Evidence Review for the US Preventive Services Task Force.

Importance: Fragility fractures result in significant morbidity.

Objective: To review evidence on osteoporosis screening to inform the US Preventive Services Task Force.

Data Sources: PubMed, Embase, Cochrane Library, and trial registries through January 9, 2024; references, experts, and literature surveillance through July 31, 2024.

Audio-Based Care for Managing Chronic Conditions in Adults: A Systematic Review.

Background: There is a lack of consensus on the effectiveness of audio-based care to manage chronic conditions. This knowledge gap has implications for health policy decisions and for health equity, as underserved populations are more likely to access care by telephone.

Objectives: We compared the effectiveness of audio-based care to usual care for managing chronic conditions (except diabetes).
