Rosa Maria De Santo, Luca Salvatore De Santo
In Italy in 2017 out of 2738 assessments of death, there was a 28.7% of oppositions of family members to the removal of organs post-mortem. This opposition is a serious limitation to the development of transplantation programs. There is a need to increase the number of transplants since transplantation grants the highest quality of life, a longer survival and at a lower cost for the society. We propose the use of Narrative Medicine (MN) to reduce this opposition. "Narrative Medicine - as Charon says - fortifies clinical practice with the narrative competence to recognize, absorb, metabolize, interpret, and be moved by the stories of illness"...

Chronic traumatic encephalopathy (CTE) is a diagnosis recently discovered and described in the context of American football. It is a a neurodegenerative disease that is a consequence of repetitive brain injury such as concussion. Such injury most notably occurs in physically violent sports but can also occur in other settings, such as during military duty, where explosive blasts can cause subconcussive impacts to the head. The main clinical features of CTE involve three aspects: mood/impulsivity, suicide, and dementia...

Studies of professional American football players have shown that football-related activities lead to acute injuries and may have long-term adverse health outcomes including osteoarthritis, neurocognitive impairment, and cardiovascular disease. However, the full complement of what constitutes professional football exposure has yet to be effectively articulated. Most likely, professional football exposure encompasses a multifaceted array of experiences including head impacts and joint stresses, long-term pain medication use, dietary restrictions, and strenuous training regimens...

BACKGROUND: When participating in contact sports, (mild) head trauma is a common incident-observed in both professional and amateur sports. When head trauma results in transient neurological impairment, a sports-related concussion has occurred. Acute concussion, repetitive concussions, as well as cumulative "sub-concussive" head impacts may increase the risk of developing cognitive and behavioral deficits for athletes, as well as accelerated cerebral degeneration. While this concept has been well established for classic contact sports like American Football, Rugby, or Boxing, there is still an awareness gap for the role of sports-related concussion in the context of the world's most popular sport-Soccer...

After World War II, organized tackle football programs for boys younger than high school age grew enormously in popularity in the United States, prompting concerns from pediatricians and educators about the sport's physical and emotional health effects. At the same time, sports medicine was emerging as a sub-specialty. Examining how American sports medicine doctors and football coaches established their professional authority on youth football safety in the 1950s and 1960s reveals how their justifications for this collision sport were connected to broader cultural trends...

Low serum 25-hydroxyvitamin D [25(OH)D] concentrations are associated with high risk of insulin resistance and type 2 diabetes mellitus (T2DM) in adults. However, it is unknown whether this is the case in American collegiate football and rugby athletes. This study investigated the associations between serum 25(OH)D concentrations and glucose profiles in male collegiate football athletes. Thirty-four collegiate athletes (13 American football players and 21 collegiate rugby football players) aged 21 years were recruited...

CASE: A 27-year-old right-hand-dominant National Football League (NFL) quarterback injured his right shoulder after falling with the elbow flexed and the shoulder flexed and slightly abducted. He noted an immediate onset of right anterior shoulder pain, but was able to continue playing and throwing without notable deficit. Magnetic resonance imaging of the chest revealed an isolated tear of the pectoralis minor tendon. The patient received nonoperative local treatment and was able to start as quarterback at the next game...

BACKGROUND: Although "spear tackling" is known to be a risk factor for cervical spine injury due to axial loading of the neck, and although this technique was officially banned from American football in 1976, football-associated cervical spine injuries continue to be reported. This case highlights the importance of recognizing high-risk mechanisms for cervical spine injury, and specifically the danger of spear tackling among football players at all levels. CASE REPORT: A 16-year-old male high school football player presented to the pediatric emergency department for a neck injury sustained after spear tackling during a football game...

The ulnar collateral ligament (UCL) is the primary restraint to valgus angulation at the elbow. Injury to the UCL is increasingly common and can lead to instability, especially in athletes involved in overhead throwing. Conventional treatment is reconstruction using tendon autograft but performance levels are often restricted after long periods of rehabilitation. Modern surgical techniques have led to renewed interest in repair of the ligament, with the aim of restoring native anatomy. This has the benefit of retained proprioception and no graft harvest morbidity...

PURPOSE: Muscle mass, strength and power are important factors for performance. To improve these characteristics, periodized resistance training is used. However, there is no consensus regarding the most effective periodization model. Therefore the purpose of this study was to compare the effects of block (BLOCK) versus daily undulating periodization (DUP) on body composition, hypertrophy, strength, performance and power in adolescent American football players. METHODS: Forty-seven subjects participated in this study (M±SD age = 17±0...

CONTEXT: Treatment delays can be contributing factors in the death of American football athletes from exertional heat stroke. Ideally, clinicians begin cold-water immersion (CWI) to reduce rectal temperature (Trec ) to <38.9°C within 30 minutes of collapse. If delays occur, experts recommend Trec cooling rates that exceed 0.15°C/min. Whether treatment delays affect CWI cooling rates or perceptual variables when football uniforms are worn is unknown. OBJECTIVE: To answer 3 questions: (1) Does wearing a football uniform and delaying CWI by 5 minutes or 30 minutes affect Trec cooling rates? (2) Do Trec cooling rates exceed 0...

The popular method of organising youth sport participants into age divisions, based solely on their birthdate, can result in an imbalance of the distribution of players. This is known as relative age effect (RAE), which inadvertently creates bias and is associated with deleterious short and long-term consequences. The overall purpose of this study was to examine how the potential for RAE is mitigated when simultaneously accounting for additional player criterion, supplementary to age. A mid-Atlantic American youth football registration database was acquired, including chronological (age), anthropometric (weight), and competency (skill) factors...
