Palliative care referrals in patients with pulmonary arterial hypertension: The Pulmonary Hypertension Association Registry.

Background: Pulmonary arterial hypertension (PAH) is a life limiting disease with substantial symptom burden and healthcare utilization. Palliative care alleviates physical and emotional symptoms for patients with serious illness, and has been underutilized for these patients.

Objective: To characterize patients with PAH referred to palliative care and identify predictors of referral.

Maternal cardiovascular disease risk factors as predictors of preterm birth in California: a case-control study.

Objective: To determine whether maternal cardiovascular disease (CVD) risk factors predict preterm birth.

Design: Case control.

Setting: California hospitals.

One-Pot Solvothermal Synthesis of Highly Emissive, Sodium-Codoped, LaF₃ and BaLaF₅ Core-Shell Upconverting Nanocrystals.

We report a one-pot solvothermal synthesis of sub-10 nm, dominant ultraviolet (UV) emissive upconverting nanocrystals (UCNCs), based on sodium-codoped LaF₃ and BaLaF₅ (0.5%Tm; 20%Yb) and their corresponding core@shell derivatives. Elemental analysis shows a Na-codopant in these crystal systems of ~20% the total cation content; X-ray diffraction (XRD) data indicate a shift in unit cell dimensions consistent with these small codopant ions.
