Objective:
The purpose of this study is to define the publication patterns and the impact of self-citation among program directors of surgical fellowships.
Methods:
Program directors were identified through the respective fellowship accrediting council and association websites for eleven surgical subspecialties. Using the Scopus database, the number of publications, citations, self-citations, and h-indices were calculated.
Results:
781 program directors were identified. The mean number ± SD of publications, citations, and h-index for the cohort were 74.6 ± 88.2, 2141 ± 3486, and 18.8 ± 14.5, respectively. The self-citation rate for the entire cohort was 3.17%. After excluding self-citations, the h-index remained unchanged for 72% of surgeons. After propensity score matching for h-index, colorectal surgeons (1.48%, p = 0.04) had significantly lower self-citation rates.
Conclusion:
Overall, self-citation is infrequent among program directors of surgical fellowships. There is a lower rate of self-citation among colorectal surgeons when compared to program directors in other specialties with similar baseline metrics.

Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
