Patient perceptions of nonmelanoma skin cancer before diagnosis.

Background: There is a paucity of data regarding patient perceptions of nonmelanoma skin cancer (NMSC).

Objective: To describe patients' perceptions of skin lesions before a diagnosis of NMSC.

Methods: This was a descriptive study in a private practice setting.

A randomized controlled trial of a controlled breathing protocol on heart rate variability following myocardial infarction or coronary artery bypass graft surgery.

Objectives: To determine whether a controlled breathing programme increases heart rate variability following an acute myocardial infarction and/or coronary artery bypass graft surgery.

Rationale: Heart rate variability is reduced following a myocardial infarction, and low heart rate variability is associated with a high mortality risk. By changing tidal volume and rate of breathing, individuals can alter beat-to-beat heart rate variability.
