Biomechanical overload syndrome: defining a new diagnosis
Chronic exertional compartment syndrome (CECS) was first described in 1956,1 but little research has been performed since then to confirm the pathological physiology. An assumption is made that elevated subfascial or intramuscular pressure during exercise causes tissue hypoxia and subsequent ischaemic pain due to decreased blood flow.2 To date, no conclusive evidence exists to demonstrate cellular hypoxic damage or decreased capillary perfusion.3 Further supposition is made regarding muscle hypertrophy, reduced compartment volume due to a decreased fascial compliance,4 and shorter periods of muscle relaxation as the underl...

Genghis khan ice marathon: preparation, strategy and the effect of exercise in an extreme cold environment in a group of experienced ultrarunners
Conclusions All athletes were experienced in ultrarunning. They shared concerns regarding competing in a remote, extreme cold environment. All were adequately prepared pre race in terms of clothing, equipment and race nutrition strategy. This level of experience contributed to the lack of complications during the race and in the post race period. No athletes experienced DOMS presumably related to lack of peripheral muscular perfusion during exercise in extreme cold.

Myocardial Perfusion Imaging with Ultra-high Resolution SPECT/CT System in Rats using Multiple Pinhole Collimator: Comparison with High-resolution Autoradiography
Conclusion: These data indicate that ultra-high resolution SPECT/CT can evaluate the severity of MI in rats, which were well correlated with the results of autoradiography. Research Support: This work has been supported by Grants-in-Aid for scientific research (No. 26461847) from the Ministry of Education, Culture, Sports, Science, and Technology, Japan.

Heat, Hydration and the Human Brain, Heart and Skeletal Muscles
AbstractPeople undertaking prolonged vigorous exercise experience substantial bodily fluid losses due to thermoregulatory sweating. If these fluid losses are not replaced, endurance capacity may be impaired in association with a myriad of alterations in physiological function, including hyperthermia, hyperventilation, cardiovascular strain with reductions in brain, skeletal muscle and skin blood perfusion, greater reliance on muscle glycogen and cellular metabolism, alterations in neural activity and, in some conditions, compromised muscle metabolism and aerobic capacity. The physiological strain accompanying progressive e...

Low Cardiorespiratory Fitness Post-COVID-19: A Narrative Review
AbstractPatients recovering from COVID-19 often report symptoms of exhaustion, fatigue and dyspnoea and present with exercise intolerance persisting for months post-infection. Numerous studies investigated these sequelae and their possible underlying mechanisms using cardiopulmonary exercise testing. We aimed to provide an in-depth discussion as well as an overview of the contribution of selected organ systems to exercise intolerance based on the Wasserman gears. The gears represent the pulmonary system, cardiovascular system, and periphery/musculature and mitochondria. Thirty-two studies that examined adult patients post-...

Foreseeing the danger in the beach chair position: Are standard measurement methods reliable?
CONCLUSION: Cerebral oximetry by NIRS may prove useful as a monitor for cerebral ischaemia. In the absence of NIRS, CHR can partially detect abnormalities but not trustable, and MAP is the most reliable method for monitoring. LEVEL OF EVIDENCE: III.

Report of a nationwide survey on actual administered radioactivities of radiopharmaceuticals for diagnostic reference levels in Japan
Conclusions This survey indicated that the administered radioactivity in diagnostic nuclear medicine in Japan had been in the convergence zone and nuclear medicine facilities in Japan show a strong tendency to adhere to the texts and guidelines. Furthermore, the administered radioactivities in Japan were within the range of variation of the EU and the SNMMI administered radioactivities.

A student technologists perspective regarding the increase in pharmacological stress testing due to the SARS-CoV-2pandemic in a large urban area.
Conclusion: MPI studies, in large urban areas, has increased triage from exercise to pharmacological protocol, because of the occupational and patient health hazard of exercise protocols due to the SARS-CoV-2 pandemic. Patients undergoing either an exercise or to the pandemic in a large urban area. Pharmacological stress test, regardless of the original order, will be assessed and correctly diagnosed for CAD, if present, with consistent findings using either of these two stresses protocols for MPI. As a student technologist, it is important to consider all aspects of procedures and the effect different protocols can have o...

Resident Education in the time of the COVID-19 Pandemic
Conclusions: The feedback from the residents has been positive especially with the utilization of Zoom, continuing in person readouts at our main hospital site and onsite teaching. Currently, the Radiology department is in process to obtain cameras for the PACS such that residents, especially the more junior who may not be as familiar with the faculty, will have an enhanced interactive experience more akin to traditional in person readouts. Nuclear medicine presents a weekly lecture series that is given via Zoom and depending on the location of the presenting attending, the presentations are sometimes given in the traditio...

Comparison of Magnetic Resonance Imaging With Radionuclide Methods of Evaluating the Kidney
Nuclear medicine and MRI provide information about renal perfusion, function (glomerular filtration rate), and drainage. Some tracers that are used in nuclear medicine (technetium-diethylene triamine pentaacetic acid ([99mTc-DTPA] and 51chromium-EDTA) and some contrast media (CM) that are used for MRI (gadolinium-DTPA for instance) share the same pharmacokinetic properties, though, detection techniques are different (low-spatial resolution 2-dimensional projection with a good concentration-to-signal linearity for nuclear medicine and high-resolution 3-dimensional localization with nonlinear behavior for MRI). Thus, though ...
