Technology use among patients with cardiovascular disease: an assessment of patient need for a technology enabled behavioural change intervention.

Effective Cardiac Rehabilitation (CR) can significantly improve mortality and morbidity rates in relation to cardiovascular disease; however, uptake of traditional community-based long-term is very low. PATHway (Physical Activity Towards Health) will provide individualized rehabilitation programs, through an internet-enabled sensor-based home exercise platform that allows remote participation. The purpose of this study was to assess the level of interest and use of technology by individuals living with CVD in order to inform the design of a technology-enabled CR programme. Method: A technology usage questionnaire based on a previous study investigating the role of technology and mHealth in a CVD population was used (Dale et al., 2014) to ascertain the current level of technology use. All patients attending the Phase Four community cardiac rehabilitation HeartSmart programme (MedEx) were recruited (N=67; 66.2 years, SD= 8.55, Males =76.1%, Females=20.9%). Results: Technology usage was high with 60% of participants owning a smartphone and 85% accessing the internet (54% of whom access it everyday). Participants endorsed the idea of technology enabled cardiac rehabilitation, indicating that they found the idea ‘ appealing’. 79% were interested in receiving ongoing CR support via their smartphones, 79% were interested in receiving CR via the internet. It was found that 52% of patients found the idea of a virtual rehabilitation class appealing. Conclusion: This study provides support for the patient need for a technology enabled behavioural change intervention, specifically through the provision of an internet-enabled sensor-based home exercise platform that allows remote participation in CR exercise programs

A genetic predisposition score for muscular endophenotypes predicts the increase in aerobic power after training: the CAREGENE study

<p>Abstract</p> <p>Background</p> <p>It is widely accepted that genetic variability might explain a large part of the observed heterogeneity in aerobic capacity and its response to training. Significant associations between polymorphisms of different genes with muscular strength, anaerobic phenotypes and body composition have been reported. Muscular endophenotypes are positively correlated with aerobic capacity, therefore, we tested the association of polymorphisms in twelve muscular related genes on aerobic capacity and its response to endurance training.</p> <p>Methods</p> <p>935 Coronary artery disease patients (CAD) who performed an incremental exercise test until exhaustion at baseline and after three months of training were included. Polymorphisms of the genes were detected using the invader assay. Genotype-phenotype association analyses were performed using ANCOVA. Different models for a genetic predisposition score (GPS) were constructed based on literature and own data and were related to baseline and response VO₂scores.</p> <p>Results</p> <p>Carriers of the minor allele in the R23K polymorphism of the glucocorticoid receptor gene (<it>GR</it>) and the ciliary neurotrophic factor gene (<it>CNTF</it>) had a significantly higher increase in peakVO₂after training (p < 0.05). Carriers of the minor allele (C34T) in the adenosine monophosphate deaminase (<it>AMPD1</it>) gene had a significantly lower relative increase (p < 0.05) in peakVO₂. GPS of data driven models were significantly associated with the increase in peakVO₂after training.</p> <p>Conclusions</p> <p>In CAD patients, suggestive associations were found in the <it>GR, CNTF </it>and the <it>AMPD1 </it>gene with an improved change in aerobic capacity after three months of training. Additionally data driven models with a genetic predisposition score (GPS) showed a significant predictive value for the increase in peakVO₂.</p

PATHway: decision support in exercise programmes for cardiac rehabilitation

Rehabilitation is important for patients with cardiovascular diseases (CVD) to improve health outcomes and quality of life. However, adherence to current exercise programmes in cardiac rehabilitation is limited. We present the design and development of a Decision Support System (DSS) for telerehabilitation, aiming to enhance exercise programmes for CVD patients through ensuring their safety, personalising the programme according to their needs and performance, and motivating them toward meeting their physical activity goals. The DSS processes data originated from a Microsoft Kinect camera, a blood pressure monitor, a heart rate sensor and questionnaires, in order to generate a highly individualised exercise programme and improve patient adherence. Initial results within the EU-funded PATHway project show the potential of our approach

Imaging PARP with [18F]rucaparib in pancreatic cancer models

PURPOSE: Rucaparib, an FDA-approved PARP inhibitor, is used as a single agent in maintenance therapy to provide promising treatment efficacy with an acceptable safety profile in various types of BRCA-mutated cancers. However, not all patients receive the same benefit from rucaparib-maintenance therapy. A predictive biomarker to help with patient selection for rucaparib treatment and predict clinical benefit is therefore warranted. With this aim, we developed [18F]rucaparib, an 18F-labelled isotopologue of rucaparib, and employed it as a PARP-targeting agent for cancer imaging with PET. Here, we report the in vitro and in vivo evaluation of [18F]rucaparib in human pancreatic cancer models. METHOD: We incorporated the positron-emitting 18F isotope into rucaparib, enabling its use as a PET imaging agent. [18F]rucaparib binds to the DNA damage repair enzyme, PARP, allowing direct visualisation and measurement of PARP in cancerous models before and after PARP inhibition or other genotoxic cancer therapies, providing critical information for cancer diagnosis and therapy. Proof-of-concept evaluations were determined in pancreatic cancer models. RESULTS: Uptake of [18F]rucaparib was found to be mainly dependent on PARP1 expression. Induction of DNA damage increased PARP expression, thereby increasing uptake of [18F]rucaparib. In vivo studies revealed relatively fast blood clearance of [18F]rucaparib in PSN1 tumour-bearing mice, with a tumour uptake of 5.5 ± 0.5%ID/g (1 h after i.v. administration). In vitro and in vivo studies showed significant reduction of [18F]rucaparib uptake by addition of different PARP inhibitors, indicating PARP-selective binding. CONCLUSION: Taken together, we demonstrate the potential of [18F]rucaparib as a non-invasive PARP-targeting imaging agent for pancreatic cancers

Landowners’ Сolonization of Bashkiria

The “closed city” practice, exercised in Ufa province before 1735, together with the unfavourable political situation led to the bad crisis of estate landownership of the Ufa district. The population polls of the mid-XVII — beginning of XVIII cc. justify the fact that Ufa noblemen had to succumb to the fate of socially deprived Siberian nobility, practically devoid of serf peasants. The beginning of the largest-scale Bashkir insurrection of 1735–1736 made the administration review its attitude to the former ban on Bashkir estate lands sale. In the history of Bashkir landowners’ colonization the edict dated February 11th, 1736, allowing the local officers and officials to buy lands from Bashkir communities, was of principal importance. This procedure was exercised simultaneously with the establishment of the Russian government military control over the south-eastern border, separating Bashkir estate lands from Kazakh migratory tribes. From this moment on there is a stop in diplomatic contacts of the Bashkir elite with the governors of the Middle Asia, Kazakhstan and Turkey that meant the complete loss of political subjection by the Bashkirs. Bashkir communities become active participants of economic relations with Russian landowners, plant owners and the state institutions. Russian government preserved estate dynastic rights with the Bashkirs and refused from large-scale operations on the expropriation of Bashkir lands, transferring the mission of colonization to private persons, who had to arrange the issue with the local communities by themselves. The permission to sell estate lands forced landowners to active participation in the system of Russian legal relations, to contact the Russian government and customers

Isometric exercise training for hypertension

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: We will aim to conduct a systematic review and meta-analysis quantifying the effects of IRT on systolic, diastolic, mean arterial and 24-hour ambulatory blood pressure. We will also quantify changes in heartrate and heartrate variability, and will attempt to determine which patient demographics and exercise program characteristics are associated with the largest blood pressure changes

The development and co-design of the PATHway intervention: a theory-driven eHealth platform for the self-management of cardiovascular disease.

Background Cardiovascular diseases (CVD) are a leading cause of premature death and disability and an economic burden worldwide. International guidelines recommend routine availability and delivery of all phases of cardiac rehabilitation (CR). Uptake of traditional cardiac rehabilitation remains suboptimal, as attendance at formal hospital-based CR programmes is low, with community-based CR rates and individual long-term exercise maintenance even lower. Home-based CR programs have been shown to be equally effective in clinical and health-related quality of life outcomes, and yet are not readily available. Purpose The aim of the current study was to develop the PATHway intervention (Physical Activity Towards Health) for the self-management of cardiovascular disease. Increasing physical activity in individuals with CVD was the primary behaviour. Methods The PATHway intervention was theoretically informed by the Behaviour Change Wheel (BCW) and Social Cognitive Theory (SCT). All relevant intervention functions, behaviour change techniques (BCTs) and policy categories were identified and translated into intervention content. Furthermore, a person-centred approach was adopted involving an iterative co-design process and extensive user-testing. Results Education, enablement, modelling, persuasion, training and social restructuring were selected as appropriate intervention functions. Twenty-two BCTs, linked to the 6 intervention functions and 3 policy categories were identified for inclusion and translated into PATHway intervention content. Conclusions This paper details the use of the BCW and SCT within a person-centred framework to develop an eHealth intervention for the self-management of CVD. The systematic and transparent development of the PATHway intervention will facilitate the evaluation of intervention effectiveness and future replication. The Template for Intervention Description and Replication (TIDieR) checklist was used to specify details of the intervention including the who, what, how and where of proposed intervention delivery

Lifestyle management of hypertension: International Society of Hypertension position paper endorsed by the World Hypertension League and European Society of Hypertension

Hypertension, defined as persistently elevated systolic blood pressure (SBP) >140 mmHg and/or diastolic blood pressure (DBP) at least 90 mmHg (International Society of Hypertension guidelines), affects over 1.5 billion people worldwide. Hypertension is associated with increased risk of cardiovascular disease (CVD) events (e.g. coronary heart disease, heart failure and stroke) and death. An international panel of experts convened by the International Society of Hypertension College of Experts compiled lifestyle management recommendations as first-line strategy to prevent and control hypertension in adulthood. We also recommend that lifestyle changes be continued even when blood pressure-lowering medications are prescribed. Specific recommendations based on literature evidence are summarized with advice to start these measures early in life, including maintaining a healthy body weight, increased levels of different types of physical activity, healthy eating and drinking, avoidance and cessation of smoking and alcohol use, management of stress and sleep levels. We also discuss the relevance of specific approaches including consumption of sodium, potassium, sugar, fibre, coffee, tea, intermittent fasting as well as integrated strategies to implement these recommendations using, for example, behaviour change-related technologies and digital tools

A Multi-Center Comparison of VO2peak Trainability Between Interval Training and Moderate Intensity Continuous Training

There is heterogeneity in the observed VO2peak response to similar exercise training, and different exercise approaches produce variable degrees of exercise response (trainability). The aim of this study was to combine data from different laboratories to compare VO2peak trainability between various volumes of interval training and Moderate Intensity Continuous Training (MICT). For interval training, volumes were classified by the duration of total interval time. High-volume High Intensity Interval Training (HIIT) included studies that had participants complete more than 15 min of high intensity efforts per session. Low-volume HIIT/Sprint Interval Training (SIT) included studies using less than 15 min of high intensity efforts per session. In total, 677 participants across 18 aerobic exercise training interventions from eight different universities in five countries were included in the analysis. Participants had completed 3 weeks or more of either high-volume HIIT (n = 299), low-volume HIIT/SIT (n = 116), or MICT (n = 262) and were predominately men (n = 495) with a mix of healthy, elderly and clinical populations. Each training intervention improved mean VO2peak at the group level (P \u3c 0.001). After adjusting for covariates, high-volume HIIT had a significantly greater (P \u3c 0.05) absolute VO2peak increase (0.29 L/min) compared to MICT (0.20 L/min) and low-volume HIIT/SIT (0.18 L/min). Adjusted relative VO2peak increase was also significantly greater (P \u3c 0.01) in high-volume HIIT (3.3 ml/kg/min) than MICT (2.4 ml/kg/min) and insignificantly greater (P = 0.09) than low-volume HIIT/SIT (2.5 mL/kg/min). Based on a high threshold for a likely response (technical error of measurement plus the minimal clinically important difference), high-volume HIIT had significantly more (P \u3c 0.01) likely responders (31%) compared to low-volume HIIT/SIT (16%) and MICT (21%). Covariates such as age, sex, the individual study, population group, sessions per week, study duration and the average between pre and post VO2peak explained only 17.3% of the variance in VO2peak trainability. In conclusion, high-volume HIIT had more likely responders to improvements in VO2peak compared to low-volume HIIT/SIT and MICT
