The aim of this review was to identify the main variables for load monitoring in training and competition situations in wheelchair sports. Studies were identified from a systematic search of three databases (PubMed, Web of Science, and SportDiscuss), with search phrases constructed from MeSH terms, alone or in combination, limited to English-language literature, and published up to January 2016. Our main findings were that variables related to external load (distance, speed, and duration) are used to monitor load in competition...

REVIEW
Fred Shaffer, J P Ginsberg
Healthy biological systems exhibit complex patterns of variability that can be described by mathematical chaos. Heart rate variability (HRV) consists of changes in the time intervals between consecutive heartbeats called interbeat intervals (IBIs). A healthy heart is not a metronome. The oscillations of a healthy heart are complex and constantly changing, which allow the cardiovascular system to rapidly adjust to sudden physical and psychological challenges to homeostasis. This article briefly reviews current perspectives on the mechanisms that generate 24 h, short-term (~5 min), and ultra-short-term (<5 min) HRV, the importance of HRV, and its implications for health and performance...

Tissue fibrosis, an accumulation of extracellular matrix proteins such as collagen, accompanies cardiac ageing in humans and this is linked to an increased risk of cardiac failure. The mechanisms driving age-related tissue fibrosis and cardiac dysfunction are unclear, yet clinically important. Drosophila is amenable to the study of cardiac ageing as well as collagen deposition; however it is unclear whether collagen accumulates in the ageing Drosophila heart. This work examined collagen deposition and cardiac function in ageing Drosophila, in the context of reduced expression of collagen-interacting protein SPARC (Secreted Protein Acidic and Rich in Cysteine) an evolutionarily conserved protein linked with fibrosis...

Sleep disordered breathing (SDB) is known for fluctuating heart rates and an increased risk of developing arrhythmias. The current reference for heartbeat analysis is an electrocardiogram (ECG). As an unobtrusive alternative, we tested a sensor foil for mechanical vibrations to perform a ballistocardiography (BCG) and applied a novel algorithm for beat-to-beat cycle length detection. The aim of this study was to assess the correlation between beat-to-beat cycle length detection by the BCG algorithm and simultaneously recorded ECG...

OBJECTIVE: systematic monitoring has recently been implemented widely in non-obstetric departments. In the UK, Early Warning Score (EWS) systems specifically designed for the obstetric population (OEWS) are used. No information on the use of OEWS in Scandinavia has been reported. Consequently, we wanted to investigate the use of vital signs and attitude towards systematic monitoring of parturients in Denmark, Norway and Sweden. DESIGN: electronic questionnaires sent to heads of midwifery...

Cardiovascular (CV) disease is the leading cause of death and morbidity in patients with type 2 diabetes. Five CV risk factors (blood pressure, resting heart rate [HR], body weight, cholesterol levels and blood glucose) are monitored routinely as safety and efficacy endpoints in randomised clinical trials for diabetes therapies. To determine if different glucagon-like peptide-1 receptor agonists (GLP-1RAs) had varying effects on these CV risk factors, we reviewed 16 head-to-head trials directly comparing GLP-1RAs that included at least one of the five factors...

Maternal autoantibodies to Ro/SSA are often linked to congenital heart block and rarely associated with structural defects. We describe the case of a fetus with anti-Ro-mediated second-degree block at 19 weeks, which progressed to a complete block, fibroelastosis, atrioventricular valve insufficiency, and semilunar valve stenosis/insufficiency at 20, 22, 24, and 26 weeks, respectively, although the fetus received transplacental anti-arrhythmic drugs. The 2150-g fetus was vaginally delivered at 35 weeks. An external pacemaker was inserted immediately after birth and replaced with permanent pacemaker at the age of 3 months...

Recent advances of wearable computing technology have allowed continuous health monitoring in large observational studies and clinical trials. Examples of data collected by wearable devices include minute-by-minute physical activity proxies measured by accelerometers or heart rate. The analysis of data generated by wearable devices has so far been quite limited to crude summaries, for example, the mean activity count over the day. To better utilize the full data and account for the dynamics of activity level in the time domain, we introduce a two-stage regression model for the minute-by-minute physical activity proxy data...

RATIONALE: Bezold-Jarisch reflex (BJR) occurs when the cardioinhibitory receptors in the walls of ventricles are activated by various stimuli, with typical features of bradycardia, vasorelaxation, and hypotension. This reflex usually happens in parturient intrathecal anesthesia, as a result of decreased venous return by compression of inferior vena cava, but it is only rarely reported during general anesthesia. PATIENT CONCERNS: Severe bradycardia and hypotension, indicating BJR, occurred during the induction of general anesthesia in a 3-month-old female child with giant intra-abdominal teratoma...

PURPOSE: Being able to identify how an athlete is responding to training would be useful to optimise adaptation and performance. The maximal rate of heart rate increase (rHRI), a marker of heart rate acceleration has been shown to correlate with performance changes in response to changes in training load in male athletes; however, it has not been established if it also correlates with performance changes in female athletes. METHODS: rHRI and cycling performance were assessed in six female cyclists following 7 days of light training (LT), 14 days of heavy training (HT) and a 10 day taper period...

The objective is to prospectively investigate short- and mid-term changes of heart rate variability (HRV) in patients with relapsing-remitting multiple sclerosis (RRMS), being started on fingolimod. In this prospective clinical trial, patient (n = 33) with RRMS starting treatment with fingolimod underwent a time-domain-based analysis of HRV (breathing at rest, deep breath, and in response to the Valsalva maneuver) shortly before, 4.5 h and 3 months after first intake. Blood pressure changes after the Valsalva maneuver were used as a marker of the sympathetic noradrenergic system...
