Nanomedicine is yielding new and improved treatments and diagnostics for a range of diseases and disorders. Nanomedicine applications incorporate materials and components with nanoscale dimensions where novel physiochemical properties emerge as a result of size-dependent phenomena and high surface-to-mass ratio. Nanotherapeutics and in vivo nanodiagnostics are a subset of nanomedicine products that enter the human body. These include drugs, biological products, implantable medical devices, and combination products that are designed to function in the body in ways unachievable at larger scales. (...) Nanotherapeutics andin vivonanodiagnostics incorporate materials that are engineered at the nanoscale to express novel properties that are medicinally useful. These nanomedicine applications can also contain nanomaterials that are biologically active, producing interactions that depend on biological triggers. Examples include nanoscale formulations of insoluble drugs to improve bioavailability and pharmacokinetics, drugs encapsulated in hollow nanoparticles with the ability to target and cross cellular and tissue membranes and to release their payload at a specific time or location, imaging agents that demonstrate novel optical properties to aid in locating micrometastases, and antimicrobial and drug-eluting components or coatings of implantable medical devices such as stents.

Access to abortion is becoming increasingly restricted for many women in the United States. Besides the longstanding financial barriers facing low-income women in most states, a newer source of scarcity has emerged. The relatively small number of physicians willing to perform the procedure is compromising the ability of women in certain parts of the country to obtain an abortion.Do physicians have a duty to respond to this situation? Do they have a professional responsibility to ensure that abortions are reasonably available (...) to the women who want to terminate their pregnancies? Or, is abortion so morally and socially controversial as to remove any professional obligation to provide reasonable access?Both law and medical ethics have traditionally protected physicians’ freedom to refuse to perform any procedure, including abortion, that conflicts with their religious or other moral beliefs.
