Suffering is commonly seen as an unconscious effort to alleviate painful feelings of guilt. However, suffering also aims at averting loss of ego functions and hence loss of mental stability. This second function of suffering is discussed in the light of Freud's observations of characters wrecked by success and Weiss's ideas about mutual love as a threat to mental stability. Hawthorne's portrayal of Arthur Dimmesdale in The Scarlet Letter (1850), biographical material about the author, material from his diaries, and material from a psychotherapy case and an analysis illustrate the function of suffering to preserve mental stability in the face of heightened success and happiness. Hawthorne, it is argued, intuitively grasped this function of suffering in his novel.

Dynamic changes in physiologic systems have become an increasingly important topic in biomedical signal processing. To demonstrate a novel approach to this type of analysis, we recorded the cardiac and respiratory rhythms of six normal subjects over 5 minutes. We used cross-wavelet transforms to identify any correlations between these signals and then a unique approach to surrogate data generation in the frequency domain to confirm the statistical significance of the correlations that were found. The cross-wavelet transform provides a means of statistically quantifying weak correlations between systems that might otherwise not show significant interactions, while the method of surrogate data generation is a robust way of confirming a true physiological relationship.

The preparticipation physical examination (PPE) is a screening tool endorsed by numerous organizations and used to evaluate young athletes prior to competition for both medical and musculoskeletal conditions that may predispose them to injury. The cardiac portion of the examination, as recommended by the American Heart Association, is detailed specifically to detect signs or symptoms consistent with certain congenital heart conditions that may increase a young athlete's risk of sudden cardiac death (SCD). Much controversy has erupted over the years as to whether this examination has the diagnostic sensitivity to detect these conditions and prevent SCD, and whether additional modalities, such as the 12-lead electrocardiograph (ECG), should be incorporated. Given the rarity of SCD events, the large population of young athletes that would qualify yearly for the examination, and the limitations that an ECG would present, it would not be efficient to add the ECG to the standard PPE on the symptomatic athlete. More efforts should be spent in standardizing the PPE on a national level to further improve its efficiency.
