Summary
Authorship in cardiothoracic surgery journals continues to increase, with more authors per paper and shifting geographic contributions. This trend reflects evolving research demands and career progression pressures in academic surgery.
Area of Science:
- Cardiothoracic Surgery
- Academic Publishing
- Medical Research Trends
Background:
- The "publish or perish" culture significantly impacts academic surgeons.
- Previous studies indicated authorship proliferation and internationalization in cardiothoracic surgical literature.
Purpose of the Study:
- To assess the continuation of authorship proliferation and internationalization trends in leading cardiothoracic surgical journals.
- To analyze changes in author numbers and geographic origins over time.
Main Methods:
- A comprehensive review of 17,267 articles published between 2007 and 2022.
- Analysis of data from three prominent journals: European Journal of Cardiothoracic Surgery (EJCTS), Journal of Thoracic and Cardiovascular Surgery (JTCVS), and Annals of Thoracic Surgery (ATS).
- Collection of data on the number of authors and their geographic origin for each published article.
Main Results:
- A statistically significant increase in the mean number of authors per article was observed across all three journals from 2007 to 2022.
- North American institutions showed increasing dominance in JTCVS and ATS, while European contributions declined.
- Only EJCTS demonstrated a trend towards increasing internationalization.
Conclusions:
- Authorship proliferation is an ongoing trend in the top cardiothoracic surgical journals.
- The observed changes reflect the evolving demands of modern scientific research and academic career progression.
- Shifting geographic contributions suggest evolving global participation in cardiothoracic surgical research.

01:13The Cardiac Cycle
The heart beats rhythmically in a sequence called the cardiac cycle—a rapid coordination of contraction (systole) and relaxation (diastole).
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and empty blood into the...

01:27Anatomy of the Heart
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.
01:47Lung Capacity
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.
01:16The Respiratory System
The respiratory system is comprised of the organs that enable breathing. Air enters the nostrils and mouth, followed by the pharynx (throat) and larynx (voice box), which lead to the trachea (windpipe). In the thoracic cavity, the trachea splits into two bronchi that allow air to enter the lungs. The bronchi split into progressively smaller bronchioles and terminate in small groups of tiny sacs in the lungs called alveoli, where gas exchange occurs.
02:03Anatomy of the Circulatory System
The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.
01:05Breathing
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...
