An intensivist is a medical practitioner who specializes in the care of critically ill patients, most often in the intensive care unit (ICU). Intensivists can be internists or internal medicine sub-specialists (most often pulmonologists), anesthesiologists, emergency medicine physicians, pediatricians (including neonatologists), or surgeons who have completed a fellowship in critical care medicine. The intensivist must be competent not only in a broad spectrum of conditions among critically ill patients but also with the technical procedures and equipment (i.e. mechanical ventilators) used in the intensive care setting.

Peripheral artery disease (PAD) is an abnormal narrowing of arteries other than those that supply the heart or brain. When narrowing occurs in the heart, it is called coronary artery disease, and in the brain, it is called cerebrovascular disease. Peripheral artery disease most commonly affects the legs, but other arteries may also be involved – such as those of the arms, neck, or kidneys.

Surgical oncology is the branch of surgery applied to oncology; it focuses on the surgical management of tumors, especially cancerous tumors.
