Although enormous effort has focussed on how to build an effective culture in the business community, relatively little effort has addressed how to achieve this in the hospital environment, specifically related to the field of congenital heart disease teams. The examination of culture in pediatric cardiac care is particularly important for several key reasons: first, it represents high-stakes medicine, second, there are multiple stakeholders requiring collaboration between cardiologists, surgeons, anaesthesiologists, perfusionists, nursing staff, and allied health care professionals, and finally, both the patient and the family are intimately involved in the care pathway...

INTRODUCTION: On space missions one must consider the operating cost of the medical system on crew time. Medical Officer Occupied Time (MOOT) may vary significantly depending on provider skill. This pilot study assessed the MOOT Skill Effect (MOOTSkE). METHODS: An expert surgeon (ES), fifth year surgical resident (PGY5), second year surgical resident (PGY2), and an expert Emergency Physician (EP) with only 4 mo direct surgical training each performed two simulated appendectomies. The completion times for endotracheal intubation, appendectomy, and two subprocedures (multilayer tissue repair and single layer tissue repair) were recorded...

OBJECTIVE: The ejection seat is one of the most important rescue tools for military aircrews. However, the high ejection speeds place high loads on the pilots, which is mainly absorbed by the pilot's spine. The differentiated evaluation of spinal injuries is of particular importance because this has a decisive influence on the further personal life and career of the affected aircrew members. Factors influencing the occurrence of a fracture as well as the impact of a spinal injury on military flight certification have not been addressed sufficiently to date...

BACKGROUND: With the increase in crewed commercial spaceflight and expeditions to the Moon and Mars, the risk of critical surgical problems and need for procedures increases. Appendicitis and appendectomy are the most common surgical pathology and procedure performed, respectively. The habitable volume of current spacecraft ranges from 4 m³ (Soyuz) to 425 m³ (International Space Station). We investigated the minimum volume required to perform an appendectomy and compared that to habitable spacecraft volumes...

OBJECTIVES: Presurgical identification and morphologic characterization of the peroneal perforator arteries (PPAs) are essential for osseomyocutaneous flap surgery. The aim of this study was to evaluate PPAs using time-of-flight (TOF) angiography in 7 T magnetic resonance imaging in comparison with dual-energy computed tomographic angiography (CTA). MATERIALS AND METHODS: In this prospective study, TOF angiography and CTA of both lower legs were acquired before flap surgery from 07/2019 to 02/2020...

Medical evacuation (MEDEVAC) from a combat zone requires complex decision-making and coordination of assets. A MEDEVAC helicopter team transports not only battle-injured patients but also patients with urgent non-battle-related medical diagnoses from extremely remote locations and are at the mercy of terrain, weather, and enemy contact. The military represents a young population particularly susceptible to venous thoracic outlet syndrome (vTOS) given the rigorous physical activity demands. Current literature supports immediate anticoagulation and surgical decompression within 14 days of diagnosis of vTOS to prevent long-term morbidity...

Serving as a flight surgeon after intern year marks an interesting time in a young medical officer's career. It provides an opportunity for leadership and development for those we serve with in operational settings. This piece demonstrates how small, daily investments in others by leaders can dramatically change a life's trajectory.

A 15-year-old girl with a history of recurrent painful orofacial swelling was diagnosed on the basis of clinical findings, histopathological examination and imaging modalities as having primary chronic osteomyelitis of the jaw. Initial microbiological samples were performed but were inconclusive. She received multiple empirical antibiotic therapies and NSAIDs for 3 years without complete remission. Only MALDI-TOF (Matrix-Assisted Laser Desorption/Ionization-Time Of Flight) analysis after additional multiple microbiological bone samples with adequate techniques yielded the final diagnosis of bacterial chronic osteomyelitis of the jaw...

Glutathione is an antioxidant with powerful restorative and detoxifying properties, a progressive decrease in its reserves in erythrocytes and pancreas observed in pancreatic necrosis indicates a lack of functioning of the system for maintaining the level of glutathione in cells and the use of its endogenous reserve. The study of the role of glutathione metabolism enzyme genes in the risk of acute pancreatitis in this regard is especially relevant. The aim of the study was to evaluate the joint contribution of the rs11546155 and rs6119534 polymorphic loci of the GGT7 gene and some risk factors to the development of acute pancreatitis (AP)...

The air war of 1939-1945 was the world's first high-speed, high-altitude air war. The limiting factor in aerial combat was no longer the warplane's performance, but rather, the aviator's limited tolerances for exposure to the rarefied, anoxic, subzero atmosphere. Aviators flew unpressurized planes to altitudes of 20,000-35,000 feet during reconnaissance and bombing missions to evade enemy interceptors and anti-aircraft fire. At altitude, warfighter performance could be impaired by anoxia, decompression sickness, hypothermia & frostbite...

BACKGROUND: Physiological episodes are a top safety concern for aviators across the United States military. While many cases and a variety of causes for physiological episodes have been described, few cases, if any, have been reported of hyperventilation-induced hypocapnia and transient loss of consciousness. CASE REPORT: Here we describe a case of an aviator who experienced tingling extremities, confusion, and loss of consciousness during a flight. The aviator incorrectly believed he was experiencing hypoxia and continued to take multiple steps to troubleshoot the wrong underlying problem for his symptoms...

Introduction The coronavirus disease 2019 (COVID-19) pandemic has precipitated change across the aviation industry, including aeromedical standards. U.S. pilot occupational behavior regarding COVID-19 infections and vaccinations have not been well-studied. Methods We conducted an anonymous survey of 661 U.S. pilots from September 1, 2021, through December 15, 2021. Results We found 23.8% of pilots reported a history of COVID-19 infection but only 20.5% of infected pilots reported this history to an aeromedical examiner (AME)/flight surgeon...

BACKGROUND: The majority of critical care air transport (CCAT) flights are regulated, meaning that a theater-validating flight surgeon has confirmed that the patient is medically cleared for flight and that evacuation is appropriate. If the conditions on the ground do not allow for this process, the flight is unregulated. Published data are limited regarding CCAT unregulated missions to include the period of troop drawdown at the end of the Afghanistan conflict. The objective of our study was to characterize the unregulated missions within Afghanistan during troop drawdown and compare them to regulated missions during the same timeframe...

OBJECTIVE: Our primary aim was to investigate crew performance during medical emergencies with and without ground-support from a flight surgeon located at mission control. BACKGROUND: There are gaps in knowledge regarding the potential for unanticipated in-flight medical events to affect crew health and capacity, and potentially compromise mission success. Additionally, ground support may be impaired or periodically absent during long duration missions. METHOD: We reviewed video recordings of 16 three-person flight crews each managing four unique medical events in a fully immersive spacecraft simulator...

INTRODUCTION: After traumatic brain injury (TBI), cognitive, behavioral alterations and seizures frequently occur. Beside instrumental examinations, neuropsychological testing is the common clinical practice for detecting cognitive deficits. However, in highly skilled individuals, subtle changes with a large impact on fitness to fly may be neglected. CASE REPORT: A 28-yr-old Italian Air Force pilot with almost 700 flying hours suffered a TBI. After 2 yr of cognitive retraining programs, as the neuropsychological evaluation executed in a public hospital was within the standards and repeated EEGs had all been normal, the pilot was allowed to resume flying duties...

BACKGROUND: Migraine is a common disorder with significant aeromedical implications. The variability and unpredictable nature of occurrences hampers accurate assessment of future risk. This uncertainty results in a necessarily conservative approach to aeromedical recommendations, which unfortunately may lead to over-restrictive dispositions. Limited long-term follow up information is available on migraine outcomes in pilots, particularly assessing for impact of potential modifiable aggravating factors. Methods: This retrospective study reviewed 159 U...

Intraoperative critical events are rarely experienced by individual surgeons but are commonly experienced at a workforce level. Finding unfamiliar or unexpected pathology, anatomy, haemorrhage or an iatrogenic organ or structure injury cannot be completely eliminated in the complex surgical environment. It is vital that an appropriate, safe response to these infrequent events takes place to prevent possible further harm to patients. This paper introduces 'Patient, Procedure, People', a tool adapted from aviation threat and error management (TEM) training...

The target of human flight in space has changed from permanence on the International Space Station to missions beyond low earth orbit and the Lunar Gateway for deep space exploration and Missions to Mars. Several conditions affecting space missions had to be considered: for example the effect of weightlessness and radiations on the human body, behavioral health decrements or communication latency, and consumable resupply. Telemedicine and telerobotic applications, robot-assisted surgery with some hints on experimental surgical procedures carried out in previous missions, had to be considered as well...

Background: Preparation for exploration class space flight requires planning to support human life in many circumstances including healthcare emergencies such as the need for acute surgical care, a notable example of which is appendicitis. Although performing a laparoscopic appendectomy on Earth is routine for a trained general surgeon, it is far from routine for a non-surgeon working in microgravity where IVs do not drip, drains do not drain, and gaseous anesthetic is out of the question. Because the procedure for laparoscopic appendectomy is so well documented, it was the ideal procedure on which to base a study on how to deconstruct a surgical procedure to examine all actions, skills, equipment, and supplies needed for success by non-surgeons working in an extreme environment...
