Meningoencephalitis presenting in service personnel overseas may present a diagnostic challenge due to the broad range of potential differential diagnosis as well as the requirement for rapid assessment and treatment. A 25-year-old Royal Marine was evacuated to the Royal Centre for Defence Medicine in Birmingham, UK, with a history of rash consistent with erythema chronicum migrans, a seizure, and lymphocytic pleocytosis after skinning reindeer in Norway. Neuroborreliosis was suspected and empirical antibiotics were administered...

William Evans
Positive cancer patient outcomes, including increased time to recurrent events, have been associated with increased counts and function of natural killer (NK) cells. NK cell counts and function are elevated following acute exercise, and the generally accepted mechanism of increased recruitment suggests that binding of epinephrine releases NK cells from endothelial tissue via decreases in adhesion molecules following. I propose that blood flow-induced shear stress may also play a role in NK cell recruitment from the endothelium...

BACKGROUND: Urine drug testing is used by health care providers to determine a patient's compliance to their prescribed regimen and to detect non-prescribed medications and illicit drugs. However, the cutoff levels used by clinical labs are often arbitrarily set and may not reflect the urine drug concentrations of compliant patients. OBJECTIVES: Our aim was to test the hypothesis that commonly used cutoffs for many prescribed and illicit drugs were set too high, and methods using these cutoffs may yield a considerable number of false-negative results...

BACKGROUND: Congenital coronary anomalies (CCAs) and coronary artery disease (CAD) arouse intense scientific and clinical interest in sports medicine and sports cardiology medical communities because of their potential to trigger sudden cardiac death (SCD) in athletes. Exercise stress testing represent the first instrumental assessment to evaluate electrocardiographic changes during effort. Coronary computed tomography angiography (CCTA) is an advanced accurate noninvasive imaging modality for excluding CAD and abnormalities of origin and course of coronary vessels...

BACKGROUND: A plateau in volume of oxygen consumption (VO2) is the primary indicator for determining if an individual has reached their maximal aerobic capacity. However, secondary criteria can also be used to identify maximal effort (i.e. lactate level, rating of perceived exertion (RPE), percent of age-predicted maximal heart rate (HR) and respiratory exchange ratio (RER)). Age and gender-specific secondary criteria have been developed for the general population, but no secondary criteria have been established for pregnant women...

BACKGROUND: This study investigated the effects of detraining on breathing pattern. The aim of this study was to evaluate the effect of a sixweek detraining period on breathing patterns and ventilatory efficiency. METHODS: Fourteen young soccer players were evaluated at the end of a competitive season and after a sixweek detraining period. Assessment of respiratory efficiency was based on VE/VCO2 slope changes below 70% of exercise intensity. All participants underwent twice an incremental graded exercise test up to exhaustion...

A significant proportion of healthy seniors report difficulty swallowing, thought to result from age-related decline in muscle bulk/function. Effortful Swallowing (ES) is used both as a compensatory maneuver to improve pharyngeal propulsion/clearance and has been proposed as an exercise to improve pharyngeal strength. This study sought to quantify the immediate kinematic, temporal, and functional changes during an ES maneuver to quantify its exercise potential to combat age-related changes in swallowing. Videofluoroscopy data were collected from 44 healthy seniors (21 male) over 65 years old (mean = 76...

An 83-year-old man underwent exercise stress test with single photon emission computed tomography (SPECT) myocardial perfusion imaging for new electrocardiogram (EKG) changes. The stress EKG did not show any significant changes. Myocardial perfusion imaging with SPECT demonstrated an inferior wall defect and extracardiac uptake of nuclear tracer. Simultaneous cardiac computed tomography performed for attenuation correction showed presence of intrapericardial hepatic tissue in an anterior diaphragmatic hernia...

In blunt force trauma to the head caused by attacks with blunt instruments, contact forces can be estimated based on the conservation of momentum if impact velocities are known. The aims of this work were to measure maximum striking velocities and to examine the influence of rod parameters such as rod mass and length as well as volunteer parameters such as sex, age, body height, body mass, body mass index and the average amount of physical exercise. Steel rods with masses of 500, 1000 and 1500 g as well as lengths of 40, 65 and 90 cm were exemplarily tested as blunt instruments...

The purpose of this study was to examine the effect of a single bout of exercise on neurocognitive function in preadolescent children and young adults by determining the modulatory role of age and the neuroelectrical mechanism(s) underlying the association between acute exercise and executive function. Twenty preadolescents and 20 young adults completed the Stroop test, and neuroelectrical activity was recorded during two treatment sessions performed in a counterbalanced order. Exercise treatments involved moderate intensity aerobic exercise for 20 min as the main exercise and two 5 min periods of warm-up and cool-down...

To determine whether age affects cycling efficiency and the energy cost of walking (Cw), 190 healthy adults, ages 18-81 yr, cycled on an ergometer at 50 W and walked on a treadmill at 1.34 m/s. Ventilation and gas exchange at rest and during exercise were used to calculate net Cw and net efficiency of cycling. Compared to the 18-40 yr age group (2.17 ± 0.33 J/kg/m), net Cw was not different in the 60-64 yr (2.20 ± 0.40 J/kg/m) and 65-69 yr (2.20 ± 0.28 J/kg/m) age groups, but was significantly (P < 0...

The aim of the present study was to examine whether transient receptor potential melastatin 2 (TRPM2) plays a role in muscle fiber type transition during exercise. Mice were trained at a speed of 12 m/min at a slope of 0 ° for 60 min 5 consecutive d/wk for 4-wk. Exhaustion tests were performed on the treadmill (the speed was set at 6 m/min at a slope of 0° and increased at a rate of 1 m/min every 6 min). Isolated primary skeletal muscle cells from TRPM2 knockout (KO) mice showed lower amplitudes of electrical stimuli (ES)-induced Ca(2+) signals when compared to wild-type (WT) mice, due to a defect in Ca(2+) influx...

BACKGROUND: Increased concentrations of eosinophils in blood and sputum in chronic obstructive pulmonary disease (COPD) have been associated with increased frequency of exacerbations, reduced lung function, and corticosteroid responsiveness. We aimed to assess whether high eosinophil concentrations in either sputum or blood are associated with a severe COPD phenotype, including greater exacerbation frequency, and whether blood eosinophils are predictive of sputum eosinophils. METHODS: We did a multicentre observational study analysing comprehensive baseline data from SPIROMICS in patients with COPD aged 40-80 years who had a smoking history of at least 20 pack-years, recruited from six clinical sites and additional subsites in the USA between Nov 12, 2010, and April 21, 2015...

AIMS: Although anomalous origin of left (AOLCA) and right coronary artery (AORCA) from the wrong sinus may cause sudden death (SD) in athletes, early diagnosis and management of these anomalies are still challenging. We analysed clinical/instrumental profiles of athletes identified with AOLCA/AORCA focusing our attention on diagnosis, management and follow-up. METHODS AND RESULTS: We report 23 athletes (17 males, mean age 27±17yrs.), 6 with AOLCA and 17 with AORCA...

INTRODUCTION: Bandage application does not exert consistent compression pressure, leading to extremely variable compression when applied to patients. A new elastic bandage can exert a predefined pressure independently of healthcare providers and the size of the wrapped limb. The bandage system includes a series of non-stretchable patches that when applied to the bandage make it stiff. The aim of this work was to assess, in an experimental setting, the venous ejection fraction (EF) from the lower leg and the tolerability of this new bandage in a group of patients affected by superficial venous incompetence...

BACKGROUND: Mitochondrial diseases are a group of multisystem heterogeneous diseases caused by pathologic dysfunction of the mitochondrial respiratory chain. A wide range of clinical expression has been described. However, pulmonary hypertension has rarely been described in association with mitochondrial disease until the past decade, and there is no currently recognized treatment for the pulmonary hypertension complicated with mitochondrial disorder. PATIENT CONCERNS: We reported the case of a 15-year-old boy who presented with shortness of breath and exercise limitation after a cold, and the diagnosis of pulmonary hypertension was confirmed by right heart catheter...

BACKGROUND: COPD patients experience a sustained deterioration of several capacities. Those with severe COPD undergo a considerable decline in their physical and functional capacities, but pulmonary rehabilitation (PR) is used to reduce the weakness of such patients. To date, neuromuscular electrical stimulation (NMES) has been used in acute COPD patients but NMES superimposed onto voluntary muscular contraction has not been tested in COPD patients. AIM: The aim of this study was to evaluate the effects of superimposed NMES on the cardiorespiratory performance and functionality of severe COPD patients undergoing a home-based rehabilitation program...
