  • * A large study involving nearly 10,000 DCM cases and close to a million controls identified 70 significant genetic locations linked to the disease, revealing the importance of heart muscle cells in its development.
  • * The research also indicates that factors like higher body weight and blood pressure may contribute to DCM, and genetic risk scores can help predict the condition across different populations.

Purpose: Nonunion of bicondylar tibial plateau (BTP) fractures following open reduction internal fixation (ORIF) is rare but challenging. We report a case series of aseptic BTP nonunions, approaches to treatment, and long-term outcomes.

Methods: Retrospective case series of aseptic nonunion in operatively treated BTP fractures.

Platelet-rich plasma (PRP) is an autologous blood product containing concentrated platelets, growth factors, and anti-inflammatory cytokines that promote healing and regeneration. Platelets release active components through a degranulation process, which is inhibited by certain nonsteroidal anti-inflammatory drugs (NSAIDs). Current deferral guidelines are not established, but NSAIDs are expected to have a time-dose relationship with platelet inhibition.

Implementing self-injection (SI) of subcutaneous depot-medroxyprogesterone acetate (DMPA-SC) is a key self-care strategy for sexual and reproductive health, but SI uptake remains low, and assertions about the potential of SI to increase women's control over contraceptive use lack evidence. We sought to qualitatively explore how women with diverse contraceptive experiences-including those with and without experience using SI-view the benefits and challenges of SI as compared to other methods. We conducted 241 in-depth interviews with women across four sub-Saharan African countries and found alignment between the perceived and experienced benefits of SI across our diverse sample.
