Primary care clinicians are uniquely situated to reduce unintended pregnancy in the context of a patient's medical comorbidities, social circumstance, and gender identity. New evidence regarding contraception use has emerged in recent years. The copper intrauterine device is the most effective option for emergency contraception, with similar effectiveness found for the levonorgestrel-releasing intrauterine system, 52 mg, and both offer extended future contraception. ⋯ Subcutaneous depot medroxyprogesterone acetate, 104 mg, a newer formulation with prefilled syringes, can be safely self-administered every 13 weeks. Because bone density loss appears to be reversible, the American College of Obstetricians and Gynecologists recommends considering use of depot medroxyprogesterone acetate beyond two years despite an FDA boxed warning about increased fracture risk. Testosterone does not prevent pregnancy but is safe to use with hormonal contraception; thus, transgender and gender-diverse patients with a uterus can be offered the full range of contraceptive options.

Thrombocytopenia is a platelet count of less than 150 × 103 per μL and can occur from decreased platelet production, increased destruction, splenic sequestration, or dilution or clumping. Patients with a platelet count greater than 50 × 103 per μL are generally asymptomatic. Patients with platelet counts between 20 and 50 × 103 per μL may have mild skin manifestations such as petechiae, purpura, or ecchymosis. ⋯ Transfusion of platelets is recommended when patients have active hemorrhage or when platelet counts are less than 10 × 103 per μL, in addition to treatment (when possible) of underlying causative conditions. It is important to ensure adequate platelet counts to decrease bleeding risk before invasive procedures; this may also require a platelet transfusion. Patients with platelet counts of less than 50 × 103 per μL should adhere to activity restrictions to avoid trauma-associated bleeding.

Each year, malaria causes an estimated 500,000 deaths worldwide. Most of these deaths occur in Africa and disproportionally affect children younger than five years worldwide. Human malarial disease is caused by protozoan parasites of the genus Plasmodium. ⋯ Severe malaria is mainly caused by Plasmodium falciparum. Children, pregnant patients, and people who are not from endemic regions are at highest risk of severe malaria. Intravenous artesunate is the treatment of choice for severe malaria.
