'I never thought exercise could help improve my sleep': experiences of people with rheumatoid arthritis on the impact of an 8-week walking-based exercise intervention in improving their sleep. Rheumatol Adv Pract 2024; 8:rkae008. [PMID: 38293633 PMCID: PMC10827360 DOI: 10.1093/rap/rkae008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Accepted: 12/29/2023] [Indexed: 02/01/2024] Open
Abstract
Objective The purpose of this study was to explore the experiences of people with RA of participating in an exercise intervention to improve their sleep. Methods Using a qualitative descriptive design, semi-structured face-to-face interviews were conducted with 12 people with RA who had completed an 8-week walking-based exercise intervention to improve their total sleep time, sleep quality and sleep disturbance. Data were analysed using thematic analysis. Results Four themes were generated: positive impact of exercise on participants' sleep ('I really didn't think any type of exercise would help me sleep better, if I'm honest'); positive experiences of the exercise intervention ('I learnt so much regarding walking that I didn't even think about'); clear mental health benefits ('If you don't sleep well then it will have a knock-on effect to your mental health'); and achieving empowerment and ownership when exercising ('I feel empowered now and confident that I'm not doing harm to myself'). Conclusion The findings demonstrated that participants had not expected exercise to improve their sleep. Although there is a growing consensus that exercise will benefit sleep and mitigate some disease symptoms, research is severely lacking in people with RA.

Results from Ireland North and South's 2022 report card on physical activity for children and adolescents. J Exerc Sci Fit 2024; 22:66-72. [PMID: 38173796 PMCID: PMC10762465 DOI: 10.1016/j.jesf.2023.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 10/09/2023] [Accepted: 12/06/2023] [Indexed: 01/05/2024] Open
Abstract
Background The Ireland North and South Report Card on Physical Activity (PA) for Children and Adolescents aims to monitor progress in PA participation across a range of internationally established indicators. Methods Data were collated for 11 indicators and graded following the harmonised Active Healthy Kids Global Alliance report card process. Six representative studies (sample size range n = 898 to n = 15,557) were primarily used in the grading, with many indicators supplemented with additional studies and reports. Data collected since the implementation of COVID-19 public health measures in March 2020 were excluded. Results Grades were awarded as follows: 'Overall physical activity', C-; 'Organised Sport and Physical Activity', C; 'Active Play', INC; 'Sedentary Behaviours', C-; 'Physical Fitness', INC; 'Family and Peers', D+; 'School', C-; 'Physical Education', D; 'Community and Environment', B+ and 'Government', B. Separate grades were awarded for disability as follows; 'Overall physical activity', F; 'Organised Sport and Physical Activity', D; 'Sedentary Behaviours', C-; 'Family and Peers', C; 'School', C- and 'Government', B. 'Active Play', 'Physical Fitness', 'Physical Education' and 'Community and Environment' were all graded INC for disability. Since the last report card in 2016, four grades remained the same, three increased ('Overall physical activity', 'School' and 'Physical Education') and two ('Family and Peers,' and 'Government') were awarded grades for the first time. Conclusion Grades specific to children and adolescents with disability were generally lower for each indicator. While small improvements have been shown across a few indicators, PA levels remain low across many indicators for children and adolescents.

Physical activity in outdoor spaces, sleep quality and general health: a pilot feasibility study. Lancet 2023; 402 Suppl 1:S45. [PMID: 37997087 DOI: 10.1016/s0140-6736(23)02094-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 09/07/2023] [Accepted: 09/22/2023] [Indexed: 11/25/2023]
Abstract
BACKGROUND Physical activity and nature exposure provide health benefits. This study aimed to test the feasibility of an intervention designed to examine the effects of environmental quality on physical activity, sleep, and health status. METHODS In this pilot feasibility study, we included 14 inactive adults from Limerick (Ireland) and Lahti (Finland), recruited using social media. The intervention was an 8-week self-guided programme of physical activity, in which participants were asked to select an outdoor route according to their convenience, engage in physical activity (walking or running) at least three times a week for at least 30 min/session, and record each session using a mobile app. Participants were provided with training sheets, self-adapted according to convenience, in an in-person meeting when detailed information was provided. Reminder messages were sent during the intervention. Time spent in moderate-to-vigorous physical activity (MVPA) was measured through an accelerometer over a 9-day measurement period (considering the 50th percentile: >P50, ≤P50). Sleep quality and general health status were self-reported. Measurements were taken in weeks 1 and 8. We analysed differences, between MVPA percentile groups and general sample, in change from week 1 to 8, using χ2 and paired t-tests, with significance at p values lower than 0·05. The study was approved by the ethics committee from the University of Limerick and Satakunta Universities. FINDINGS 26 adults were enrolled in the study between Oct 3, 2022, and Feb 9, 2023, of whom 18 (69%) were women and eight (31%) were men, with a mean age of 46 years (SD 9·7). 14 (54%) of 26 adults completed the 8-week intervention, of whom 11 were women and three were men, with a mean age of 46 years (SD 10·79). On average, participants performed their training sessions 19 times (mean 19·2, SD 9·4). Mean time in MVPA decreased from 49·7 min (SD 27·0) at week 1 to 46·7 min (32·3) at week 8 (p=0·604); mean health status score increased from 66·43 (SD 26·63) to 68·57 (26·63; p=0·586); and the frequency of good sleepers increased from 50% to 64·3% (p=0·266). In both moments, participants classified in the higher MVPA percentile group (>P50) presented higher mean health status score and higher frequency of good sleepers then those in the lower percentile group (≤P50), although the differences were not significant. INTERPRETATION Study limitations include the absence of a control group and the sample size. Although results were not significant, they were promising, since it might be an easy and low-cost strategy to increase physical activity with potential impact on public health. Lessons learned led to changes in the design, and a larger multicentre study will be carried out to understand the relationship of the variables in groups performing physical activity in green and "paved" spaces.

A Multicenter, Investigator-Blinded, Randomized Controlled Trial to Assess the Efficacy of Calf Neuromuscular Electrical Stimulation Program on Walking Performance in Peripheral Artery Disease: The ELECTRO-PAD Study Protocol. J Clin Med 2022; 11:jcm11247261. [PMID: 36555879 PMCID: PMC9784261 DOI: 10.3390/jcm11247261] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/23/2022] [Accepted: 12/01/2022] [Indexed: 12/12/2022] Open
Abstract
This paper describes a currently on-going multicenter, randomized controlled trial designed to assess the efficacy of calf neuromuscular electrical stimulation (NMES) on changes in maximal walking distance in people with lower extremity peripheral artery disease (PAD), compared with a non-intervention control-group. This study (NCT03795103) encompasses five participating centers in France. PAD participants with a predominant claudication at the calf level and a maximal treadmill walking distance ≤300 m are randomized into one of the two groups: NMES group or Control group. The NMES program consists of a 12-week program of electrical stimulations at the calf-muscle level. The primary outcome of the study is the change in maximal treadmill walking distance at 12 weeks. Main secondary outcomes include changes in the pain-free treadmill walking distance; 6 min total walking distance; global positioning system (GPS)-measured outdoor walking capacity; daily physical activity level by accelerometry; self-reported walking impairment; self-reported quality of life; ankle-brachial index; and skin microvascular function, both at the forearm and calf levels. Recruitment started in September 2019 and data collection is expected to end in November 2022.

Abstract
Abstract
Background
Physical activity contributes to the prevention of chronic illness as well as promotion of physical and mental health, but most adults remain inactive. Chronic illness affects mainly middle aged and older adults, and very little objectively measured data on physical activity behaviours and associated health outcomes of this population is published. The aims of this study are to: 1. Objectively measure physical behaviour outcomes of adults participating in the Move for Life study; 2. Develop distinct activity profiles based on six behaviour variables; 3. Investigate whether health outcomes differ across the activity profiles.
Methods
Participants were Irish adults aged 50 years and older. Using the activPAL, objectively measured data were collected on average daily: light intensity physical activity (hours); moderate to vigorous intensity physical activity (minutes); step count; time in bed (hours); standing time (hours); and waking sedentary time (hours). Data were obtained on chronic illness and health service utilisation. Validated questionnaires were used to collect data on wellbeing, loneliness and social isolation. Hierarchical cluster analysis using squared Euclidian distance was used to cluster behaviours based on similarity, using SPSS version 26. Regression models explored associations between health outcomes and activity profiles, adjusted for age and sex.
Results
Data from 485 participants were analysed, and four activity profiles were identified: sedentary (n = 50, 10.3% of total), low active (n = 295, 60.8%), moderate active (111, 22.9%) and higher active (n = 29, 6%). We will present the differences across the activity profiles for chronic illnesses, multi-morbidity, health service utilisation and validated health tools, comparing to data from the Irish Longitudinal Study on Ageing (TILDA) and the English Longitudinal Study on Ageing (ELSA).
Conclusions
The use of physical activity behaviour clusters may identify people with multi-morbidity and higher utilisation of health services. These findings could be factored into the development of future targeted physical activity interventions.

Abstract
Background Substantial evidence shows that meeting physical activity guidelines is important for disease prevention, promoting physical and mental health and quality of life. In Ireland, only 38% of older adults are sufficiently active to meet the guidelines. The primary aim of this research was to conduct a feasibility study of the Move for Life intervention to reach and help inactive adults 50+ increase their physical activity. Methods Move for Life is a feasibility cluster randomised control trial where the Local Sports Partnerships hubs are the units of randomisation and individuals within the hubs are the units of analysis. The intervention augments regular programme content with behavioural skills, social support and group cohesion strategies, and includes a peer-mentoring component. Over seven hundred (N = 733) participants registered to become part of the intervention. Most (98%, n = 724) completed baseline measures. Participants were asked to complete self-report process evaluation questionnaires immediately after and 12 weeks after their programme had finished. Interviews were conducted with participants, physical activity instructors and peer mentors. Questionnaire responses across groups were compared with tests of statistical significance. Qualitative data complemented and assisted with interpretation of quantitative findings. Results A total of 601 participants met eligibility criteria (average age 63.06 years, range 50-91, 80.4% female). The study retention rate was 63%. Reported compliance rate with intervention strategies was over 75%. The intervention group were more likely to enjoy the programme than usual provision. Intervention participants were more likely to report the programme as interesting and worth the time they invested in it, and to recommend it to a friend than usual provision. They were also more likely to report enjoying learning about different strategies to keep physically active (ORs ranging from 2.56 to 3.76). At 3-month follow up, the intervention group were more likely to be aware of their Local Sports Partnership opportunities and to have contacted their Local Sports Partnership more frequently in comparison to usual provision (all p >.05). Conclusions Move for Life is a realistic and promising augmentation to existing physical activity programmes for older adults with potential for adoption and scalability following completion of a full trial.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Type 1 diabetes (T1D) affects over 2,500 children in Ireland. Insulin replacement is the mainstay of treatment for T1D, and physical activity (PA) is an important, modifiable lifestyle factor for sustaining health. Surveillance of PA for both research and clinical purposes in paediatric T1D has been limited. This study deployed both quantitative (accelerometry) and qualitative (self-report) measures to assess habitual PA patterns in children with T1D. Twenty-one participants (9 females, 12 males) between 10 and 17 years (mean 13.7 ± 1.94 years) were recruited from an Outpatients Paediatric Diabetes Clinic. Total steps, standing time (minutes (mins)) and sitting time (mins) were recorded using the activPAL 3 microactivity monitor. Clinical parameters (HbA1c, insulin regimen, and weight centiles) were measured. A self-report diary was used to measure perceived activity levels. The findings of this study show that participant children with T1D are not achieving the required steps per day to sustain physical health (recommended minimum 11,500). Females (mean = 7,306 steps ± 5,468) achieved significantly less (p = 0.001) steps per day compared to males (10,806 steps ± 5,904). No significant differences were found between genders for sitting time or standing time. Overweight or obesity was identified in 44% of female participants and 15% of male participants. Mean HbA1c for both females 8.25% (67 mmol/mol) and males 7.97% (64 mmol/mol) was above the International Society for Pediatric and Adolescent Diabetes (ISPAD) recommended <7.0% (53 mmol/mol) for children. Further research is warranted to investigate PA promotion strategies in populations of children with paediatric T1D.

Abstract
Despite well-known benefits of physical activity, in Ireland only 38 % of older adults are sufficiently active. Behavioural interventions are rarely developed systematically and, when reported, inadequate description often becomes a barrier for subsequent replication and scalability. In this article, we describe the development and characteristics of Move for Life, an intervention to reach and help inactive adults aged 50 years and older increase their physical activity. It was designed to fit within existing group-based structured physical activity programmes run by Local Sports Partnerships, thus maximising the likelihood of translation into policy and practice. Constructs from social cognitive theory, self-determination theory, and the conceptual model of group cohesion in exercise informed the conceptual model and the development of behavioural skills, social support, and group cohesion intervention strategies. Physical activity instructors supported by peer mentors, who also contributed to sustaining the intervention, implemented these strategies. Moving away from accounts of intervention development as a relatively simple linear process, we illustrate the complex interplay of theory, evidence, practice, and real-world contextual circumstances that shaped the development of Move for Life. Against this backdrop, we discuss issues relevant to the planning and reporting of behavioural and physical activity interventions in public health.

Abstract
Background:The diagnosis and treatment of inflammatory arthritis has been transformed largely by the development of drugs that target specific molecules of the immune system. However, these changes have increased the complexity of the mechanisms of disease, its treatment and patients understanding. Patient education is needed in this area to facilitate decision making and to facilitate strong patient-partnerships in research.Objectives:The aim of this study was to examine the level of understanding of inflammatory arthritis patients and the need for strong patient-partnership in research.Methods:An online anonymous survey addressed questions about diagnosis, routine tests, medications and how they work, medication adherence, disease flare, heredity, pregnancy, and patient involvement in research.Results:There were 1,873 respondents, 1416 of which had inflammatory arthritis (IA)-RA (65.8%) and PsA (34.2%). They were predominantly female (RA 86%, PsA 85 %), aged 55±13 and 50±12. Less than 35% of patients had an understanding of diagnostic tests, what was measured and the implication for disease, with 75.5% also concerned about heredity. There was a high level of understanding of how specific medications treat inflammatory arthritis (72.9%). Adherence was also very high (>87%), with the main reasons for stopping medication without the advice of their clinician, ‘feeling better’ and ‘side effects’ however a significant proportion of patients (69.9%) reported a disease-flare following cessation of medication. Patients of childbearing age (69%) were also concerned that inflammatory arthritis reduced their chances of getting pregnant, with only 8% believing arthritis medications were safe to take during pregnancy. Finally, only 9% of patients had ever been asked to participate in a research study.Conclusion:This study demonstrates a need for the development of stronger patient-partnerships with clinicians and researchers in relation to patient education and engagement with research, to create a platform where patients can have meaningful input and involvement in future research studies.Acknowledgements:We wish to thank all the patients who contributed to this studyDisclosure of Interests:Mary Canavan: None declared, Viviana Marzaioli: None declared, Alex Donnelly: None declared, Siobhan Wade: None declared, Alexander Fraser: None declared, Tim O’Sullivan: None declared, Sinead Harney: None declared, Arthritis Ireland: None declared, Douglas Veale Speakers bureau: Abbvie, Janssen, Novartis, MSD, Pfizer, UCB, Consultant of: Abbvie, Janssen, Novartis, MSD, Pfizer, UCB, Grant/research support from: Janssen, Abbvie, Pfizer, UCB, Ursula Fearon Speakers bureau: Abbvie, Grant/research support from: Janssen, Abbvie, Pfizer, UCB

Can Optic Flow Further Stimulate Treadmill-Elicited Stepping in Newborns? Front Psychol 2021; 12:665306.

Abstract
Typically developing 3-day-old newborns take significantly more forward steps on a moving treadmill belt than on a static belt. The current experiment examined whether projecting optic flows that specified forward motion onto the moving treadmill surface (black dots moving on the white treadmill surface) would further enhance forward stepping. Twenty newborns were supported on a moving treadmill without optic flow (No OF), with optic flow matching the treadmill’s direction and speed (Congruent), with optic flow in the same direction but at a faster speed (Faster), and in a control condition with an incoherent optic flow moving at the same speed as in the Congruent condition but in random directions (Random). The results revealed no significant differences in the number or coordination of forward treadmill steps taken in each condition. However, the Faster condition generated significantly fewer leg pumping movements than the Random control condition. When highly aroused, newborns made significantly fewer single steps and significantly more parallel steps and pumping movements. We speculate the null findings may be a function of the high friction material that covered the treadmill surface.

School- and Leisure Time Factors Are Associated With Sitting Time of German and Irish Children and Adolescents During School: Results of a DEDIPAC Feasibility Study. Front Sports Act Living 2020; 2:93.

Abstract
Objective: The study aims to investigate to what extent school- and leisure time-related factors are associated with sedentary behavior during school in German and Irish children and adolescents. Methods: The study based on a sample of 198 children and adolescents surveyed in 2015. Sedentary and activity behavior were measured using the activPAL physical activity monitor. Information on socio-economic status, school- and leisure-time related factors were provided by questionnaires. Associations between school- and leisure time-related factors and sedentary time during school were estimated using linear multi-level models. Results: Access to play equipment in school was associated with reduced sitting time (hours/day) of children (ß = 0.78; 95%CI = 0.06-1.48). Media devices in bedroom and assessing the neighborhood as activity friendly was associated with increased sitting time of children (ß = 0.92; 95%CI = 0.12-1.72 and ß = 0.30; 95%CI = 0.01-0.60, respectively). The permission to use media devices during breaks was associated with increased sitting time (hours/day) of adolescents (ß = 0.37; 95% CI = 0.06-0.69). A less safe traffic surrounding at school was associated with reduced sitting time of adolescents (ß = -0.42; 95% CI = -0.80 to -0.03). Conclusion: Results suggest that school- and leisure time-related factors are associated to the sedentary behavior during school. We suggest that future strategies to reduce sedentary time should consider both contexts.

Abstract
Background:OMERACT has identified sleep quality as one of the key outcomes for people with RA [1]. Poor sleep and reduced total sleep time (TST) are common complaints among people with RA. Poor sleep can in turn lead to deterioration in function, reduce activity levels and also impact mental health. Although sleep and mental health outcomes have been identified as important, they are frequently not measured in clinical trials. Involving key stakeholders, like people with RA, is important when designing exercise interventions as it allows consideration of particular issues that may influence future intervention delivery. This study involved people with RA who participated in a pilot RCT group exercise class to improve sleep quality.Objectives:To explore participants experiences of an exercise intervention in improving sleep quality and TST, to capture their reality.Methods:A descriptive qualitative study design of face-to-face semi-structured interviews was employed. The interview schedule explored a number of areas: experience of the intervention; outcome measures used; views regarding the intervention; perceptions regarding exercise and sleep and the impact on sleep. Interviews were transcribed verbatim by a professional transcriber. Inductive thematic analysis was used as an analytical approach. Interview transcripts were read, notes made, and ideas formulated to facilitate coding. The research team searched for patterns, analysed and coded the data, and generated themes and sub-themes. Themes were reviewed by the research team to check if they worked in relation to the coded extracts and the entire data set. The COREQ checklist provided guidance.Results:Twelve females participated with a mean age of 58 (SD 7.4); mean RA diagnosis of 9.9 (SD 7.4) years; moderate to severe disability (HAQ-DI: 1.5 (SD 0.60). Four main themes were generated: 1) Positive impact of exercise on sleep -“I really didn’t think any type of exercise would help me sleep better if I’m honest.”;2) Positive experiences of exercise intervention to improve sleep-“I learnt so much regarding walking that I didn’t even think about.”;3) Clear mental health benefits –“If you don’t sleep well then it will have a knock-on effect to your mental health”; 4) Achieving empowerment and ownership when exercising -“I feel empowered now and confident that I’m not doing harm to myself”.The findings demonstrated that participants were clearly surprised that exercise could improve sleep.Conclusion:In a variety of inflammatory conditions exercise is recommended as an effective intervention for the treatment of sleeping disorders. Although there is a growing consensus that exercise will benefit sleep, research is severely lacking in those with RA. This study demonstrates that participants were clearly surprised that exercise could improve their sleep. Due to the multifactorial nature of RA, engaging in exercise may not only improve sleep quality but also mitigate some of its symptoms.References:[1]Kirwan JR, Boonen A, Harrison MJ, Hewlett SE, et al (2011) OMERACT 10 Patient Perspective Virtual Campus: Valuing health; measuring outcomes in rheumatoid arthritis fatigue, RA sleep, arthroplasty, and systemic sclerosis; and clinical significance of changes in health.

Abstract
We recorded the survival of 141 patients assessed for radical cystectomy, which included cardiopulmonary exercise testing. The median Kaplan-Meier survival estimates were: 1540 days for the whole cohort; 2200 days after cystectomy scheduled (n = 108); and 843 days without surgery. The mortality hazard remained double that expected for a matched general population, but survival was better in patients scheduled for surgery than those who were not: the mortality hazard ratio (95%CI) after cystectomy was 0.43 (0.26-0.73) the mortality hazard without surgery, p = 0.001. The mortality hazard ratios for the three-variable Bayesian Model Averaging survival model for all 141 patients were: referral for surgery (0.5); haemoglobin concentration (0.98); and efficiency of carbon dioxide output (1.05). Efficiency of carbon dioxide output was the single variable in the postoperative model (n = 108), mortality hazard 1.08 (per unit increase). The ratio of observed to expected peak oxygen consumption associated best with mortality in 33 patients not referred for surgery, hazard ratio 0.001. Our results can inform consultations with patients with invasive bladder cancer and suggest that interventions to increase fitness and haemoglobin may improve survival in patients who do and who do not undergo radical cystectomy.

Abstract
Lower extremity peripheral artery disease (PAD) induces an ischemic pain in the lower limbs and leads to walking impairment. Electrical stimulation has been used in patients with PAD, but no systematic review has been proposed to address the efficacy of the technique as a treatment for walking impairment in PAD. A systematic search was performed to identify trials focused on electrical stimulation for the treatment of walking impairment in patients with PAD in the Cochrane Central Register, PubMed, Embase, and the Web of Science. Studies were included where the primary outcomes were pain-free walking distance and/or maximal walking distance. When appropriate, eligible studies were independently assessed for quality using the Cochrane Collaboration's tool for assessing risk of bias. Five studies eligible for inclusion were identified, of which only two were randomized controlled studies. Trial heterogeneity prevented the use of the GRADE system and the implementation of a meta-analysis. Three types of electrical stimulation have been used: neuromuscular electrical stimulation (NMES, n = 3), transcutaneous electrical stimulation (n = 1), and functional electrical stimulation (n = 1). The two available randomized controlled studies reported a significant improvement in maximal walking distance (+40 m/+34% and +39 m/+35%, respectively) following a program of NMES. Owing to the low number of eligible studies, small sample size, and the risk of bias, no clear clinical indication can be drawn regarding the efficacy of electrical stimulation for the management of impaired walking function in patients with PAD. Future high-quality studies are required to define objectively the effect of electrical stimulation on walking capacity.

An evaluation of an intervention designed to help inactive adults become more active with a peer mentoring component: a protocol for a cluster randomised feasibility trial of the Move for Life programme. Pilot Feasibility Stud 2019; 5:88. [PMID: 31333875 PMCID: PMC6615191 DOI: 10.1186/s40814-019-0473-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2018] [Accepted: 06/26/2019] [Indexed: 01/14/2023] Open
Abstract
Background There is overwhelming evidence to support the promotion of physical activity in adults in terms of benefits to well-being, physical and mental health. Physical activity guidelines suggest that adults should accumulate at least 150 min of moderate to vigorous physical activity per week. In Ireland, the majority of adults do not achieve these guidelines, with costs to health and economy. ‘Move for Life’ (MFL) employs behavioural change techniques delivered by an instructor and peer mentor, using a train-the-trainer (cascade) model. This study will conduct a feasibility cluster randomised controlled trial of the MFL intervention for modifying physical activity behaviours in inactive adults aged 45 years and older. Methods The trial is set in eight Local Sports Partnership (LSP) hubs that have structured physical activity programmes. The hubs are the units of randomisation (clusters), and individuals are the units of analysis (participants). Eligible participants will contact one of the hubs, with each hub running four physical activity programmes. Each programme requires between 12–15 inactive adults, resulting in 48–60 participants per hub. Allowing for 20% dropout rate, an additional 96 people will be recruited giving a maximum sample of 576. The hub will be randomised: true control, usual programme or MFL intervention. The true control group will be given information about physical activity but will not be included in a programme for the duration of the trial; the intervention will involve the instructor training one (or more) of the participants to be a peer mentor using an educational toolkit; and usual care groups will have physical activity classes delivered as normal. Baseline data will collect physical activity measures and follow-up measurements will be obtained at 3 and 6 months. All participants will be asked to wear a device for measuring activity on the thigh (activPAL) for 7 days before commencing the programme and at 3 and 6 months. The primary objective of the study is to investigate if it is feasible to deliver the intervention and collect data on moderate to vigorous physical activity (MVPA) on all participants, thereby providing valuable information to guide sample size calculation for a future, more definitive trial.

Abstract
BACKGROUND Patients with psoriasis are at risk of a co-morbid diagnosis of depression and/or anxiety. It is therefore essential for dermatologists to have valid and effective instruments that can screen and monitor depression and anxiety symptoms in psoriasis patients. OBJECTIVE The aim of this study was to validate the Mental Health Inventory (MHI-5) as a brief measure that can be used to evaluate psychological distress related to anxiety and depression in psoriasis patients. METHODS The sample included 76 adult dermatological outpatients diagnosed with psoriasis. Participants completed the MHI-5, the Hospital Anxiety and Depression Scale (HADS) and six subscales of the Self-Compassion Scale (SCS). Confirmatory factor analysis (CFA) was applied to examine the factor structure of MHI-5. Convergent validity was examined by applying correlations among all measures. Discriminant validity was examined by applying hierarchical regression models. Reliability was examined by calculating Cronbach's alpha coefficient. RESULTS Confirmatory factor analysis showed that the proposed one-factor model has a good fit to the data. The MHI-5 demonstrated satisfactory convergent validity by yielding significant moderate to strong correlations with the HADS and with the positive and negative subscales of the SCS. Discriminant validity was also evident with being at risk of anxiety predicting MHI-5 scores above and beyond the effect of gender and age. Hierarchical regressions were not performed because a very small number of participants (n = 3) were classified at risk of depression. The MHI-5 showed high internal consistency (α = 0.84). CONCLUSION This investigation provided evidence that MHI-5 is a reliable and valid instrument that can be used to effectively capture psychological distress in psoriasis patients.

Abstract
ObjectivesIntrathecal baclofen (ITB) is a recognised treatment strategy for the management of spasticity. We have 30 years of experience, and 160 patients currently receiving treatment.DesignAn audit (Jan 13 – Jul 15) demonstrated complication rates of 4.4% (infection) and 4.92% (catheter). After this we recommended 1 vancomycin wash of the pump pocket, 2 occlusive dressing of pressure sores, 3 timely MRSA pre-screening, and this was introduced June-August 2016. We present a re-audit of the service.SubjectsAll patients admitted for ITB pump surgery between June 2016 and June 2018.MethodsThe database of patients was used, from which the patient notes were reviewed with information relating to each surgical procedure recorded.ResultsThere were 92 surgical procedures and 78 patients (M 30, F 48). 12 patients had complications, requiring 18 surgical procedures. Out of 18 surgical procedures, 10 were catheter- and 7 pump-related). Our infection rate was lower at 1% of all surgeries (compared with 4.4%), or 0.6% of all ITB pump patients per year (compared with 3.4%), and our catheter complication rate was 6.25% of all patients per year. Our annual incidence rate of all complications was 5.6% in both groups.ConclusionsThe infection risk is lower and complication rate remains stable. We will discuss factors which may influence the risk of complication, and consider recommendations for the future.

Effect of exercise modality on markers of insulin sensitivity and blood glucose control in pregnancies complicated with gestational diabetes mellitus: a systematic review. Obes Sci Pract 2018; 4:455-467. [PMID: 30338116 PMCID: PMC6180709 DOI: 10.1002/osp4.283] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2017] [Revised: 05/24/2018] [Accepted: 05/27/2018] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND/AIM Exercise can be used as a strategy to attenuate hyperglycaemia experienced during gestational diabetes mellitus (GDM). To maximize its use for clinical management, the most effective modality should be identified. The purpose of this review is to elucidate the most effective modality of exercise on insulin sensitivity and blood glucose control in pregnant women with or at risk of GDM. METHODS A search was undertaken in MEDLINE, PubMed, Scopus, CINAHL, the Cochrane Library, Embase and the Maternity & Infant Healthcare Database. Studies that met inclusion criteria were randomized controlled trials and case-controlled studies, which compared exercise interventions with standard care during pregnancy in women with or at risk of GDM. RESULTS Two interventions using resistance training, eight using aerobic exercise and two using a combination of both modalities were included. The interventions showed consistently that requirements of insulin therapy, dosage, and latency to administration were improved in the exercise groups. Less consistent results were observed for capillary blood glucose measurements; however, both modalities and combination of modalities were effective at improving blood glucose control in already diagnosed patients and pregnant women with obesity. Discrepancies in the timing of intervention, GDM diagnostic criteria, and the different measures used to assess glucose metabolism make it difficult to draw clear recommendations. CONCLUSION Exercising three times per week for 40-60 min at 65-75% age-predicted heart rate maximum using cycling, walking or circuit training as a modality improved glycaemic control in GDM patients and reduced incidence of GDM in pregnant women with obesity. Further studies looking specifically at the effects of different modalities of exercise on glucose metabolism with combined strategies to enhance insulin sensitivity should be explored to maximize benefits for GDM pregnancies. Consistency in design and delivery of exercise-only interventions is required to make recommendations on a suitable exercise prescription in this population. In practice, adherence to consensus in diagnostic cut-offs for GDM diagnosis is fundamental for standardizing future research.

A land use regression model for explaining spatial variation in air pollution levels using a wind sector based approach. THE SCIENCE OF THE TOTAL ENVIRONMENT 2018; 630:1324-1334. [PMID: 29554752 DOI: 10.1016/j.scitotenv.2018.02.317] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2017] [Revised: 02/16/2018] [Accepted: 02/27/2018] [Indexed: 06/08/2023]
Abstract
Estimating pollutant concentrations at a local and regional scale is essential in environmental and health policy decision making. Here we present a novel land use regression (LUR) modelling methodology that exploits the high temporal resolution of fixed-site monitoring (FSM) to produce a national-scale air quality model for the key pollutant NO2. The methodology partitions concentration time series from a national FSM network into wind-dependent sectors or "wedges". A LUR model is derived using predictor variables calculated within the directional wind sectors, and compared against the long-term average concentrations within each sector. Validation results, based on 15 FSM training sites, show that the model captured 78% of the spatial variability in NO2 across the Republic of Ireland. This compares favourably to traditional LUR models based on purpose-designed monitoring campaigns despite using approximately half the number of monitoring points. Results also demonstrate the value of incorporating the relative position of emission source and receptor into the empirical LUR model structure. We applied the model at a high-resolution across the Republic of Ireland to enable applications such as the study of environmental exposure and human health, assessing representativeness of air quality monitoring networks and informing environmental management and policy makers. While the study focuses on Ireland, the methodology also has potential applicability for other criteria pollutants where appropriate FSM and meteorological networks exist.

An Unusual Presentation of Pyoderma Gangrenosum Leading to Systemic Inflammatory Response Syndrome. Case Rep Dermatol 2017; 9:146-150.

Abstract
This is a report of an atypical presentation of pyoderma gangrenosum (PG) in a 26-year-old male who had a negative septic screen. The patient had a life-threatening presentation requiring an intensive care unit (ICU) admission for vasopressor support. It was thought that the likely cause of circulatory collapse was an overwhelming cytokine reaction or systemic inflammatory response syndrome (SIRS) secondary to extensive PG lesions rather than septic shock. The patient presented with multiple large ulcers, the largest being 4 cm in diameter on the central chest. He developed fevers and circulatory shock preceding his ICU admission. Microbiological specimens, including blood cultures and wound swabs, were negative for any growth (bacterial, fungal, and tuberculosis). No infective foci could be identified as a cause of hemodynamic instability. During admission, the patient's condition was complicated by multi-organ dysfunction. Wound debridement extending to the deep fascia on the anterior chest, back, bilateral shoulders, and right upper thigh was deemed necessary and performed by the plastic surgery team. Histopathology showed abundant neutrophils but could not confirm an infective process. Overall, the patient made an impressive recovery with almost complete healing of all lesions following oral prednisolone alone. Based on the history and clinical and laboratory findings, a diagnosis of PG complicated by a SIRS was favored. Very few cases of neutrophilic dermatoses have been described in this way. A similar presentation has been described in a 76-year-old female with lower-leg ulcers who developed circulatory shock and required an amputation. Lesions continued to appear despite antibiotics and surgical treatment. Septic screen was negative. She was subsequently diagnosed with PG and recovered rapidly after steroid therapy.

Abstract
PURPOSE Sleep is important in maintaining the body's circadian rhythm and in maintaining health. Aim was to investigate sleep and physical activity among people who have inflammatory arthritis and their engagement with Health Professionals. MATERIALS AND METHODS Members from a national charitable organisation for patients with arthritis and a national rheumatology health professionals society were invited to participate in separate cross-sectional surveys hosted on SurveyMonkey(R)TM. RESULTS Ninety people responded and report an average of 5.7 (SD 1.46) hours sleep per night. A majority (61%) report their sleep quality as bad, with 31% taking medications at least once a week to help sleep. There was a statistically significant association between longer years with symptoms, taking medication at least once a week and limited in their activities, when rating their sleep quality as bad. Twenty eight (65%) health professional's responded with 53% discussing sleep with their patients. CONCLUSIONS People with inflammatory arthritis report low sleep with those having symptoms longer, taking medications regularly and having limitations with their activities, reporting poorer sleep quality. Only half of health professionals discuss sleep. More research is needed in investigating poor sleep quality, disturbances, and physical activity in order to promote health and well-being in this population. Implications for Rehabilitation People with inflammatory arthritis fall far below the National Sleep Foundations' "sleep needs spectrum", which is concerning as those who have reduced levels of sleep have been associated with decreased quality of life and physical function. Due to the importance of receiving sufficient sleep, there is a need to develop education and training for health professionals in the importance of engaging their patients in their sleep quality and disturbances. The effects of physical activity interventions on poor sleep need to be examined to show if it is a positive non-pharmacological treatment approach for the management of poor sleep in patients with inflammatory arthritis.

Abstract
BACKGROUND/OBJECTIVES Patient information leaflets (PILs) are frequently provided to patients following dermatological surgery to provide advice and reassurance in the community. This evaluation reviewed the guidance specified in postoperative PILs across the 40 Australian dermatology teaching departments and clinics. METHODS All 40 departments and clinics were identified and asked to provide their postoperative information leaflets on sutured wound care (preferable) or excision biopsy (September-October 2015). For each PIL, 10 preselected parameters were evaluated. RESULTS In total, 28/40 (70%) of units responded. From these units, 11/28 (39.3%) stated they do not use a postoperative PIL. Of the 17 units that provided PILs, the mode minimum dressing duration was 24 (6/17; 35.3%) and 48 h (6/17; 35.3%). For haemostatic advice, 12 PILs specified the time to press on a bleeding wound, with the most common advice being 10 (3/12; 25%) and 20 min (3/12; 25%). Of the 14 PILs that provided analgesic advice, the mode information suggested using paracetamol only and avoiding aspirin (4/14, 28.6%). Two or more signs of infection were stated in 11/17 (64.7%) PILs; 7/17 (41.2%) advised applying petroleum jelly to the wound, almost all PILs highlighted the contact for postoperative problems 16/17 (94.1%), and 5/17 (29.4%) leaflets mentioned scarring. Altogether 8/17 (47.1%) of PILs advised on the timeframe until active exercise could resume postoperatively. CONCLUSION Guidance provided in Australian postoperative dermatological PILs is heterogeneous. A consensus checklist or template would be beneficial and ensure that advice provided to patients is more consistent; this could be adapted for local factors.

Abstract
To systematically search for the availability of evidence for exercise impacting on sleep for people who have rheumatoid arthritis. Two reviewers independently searched seven electronic databases, identified and extracted relevant studies by applying eligibility criteria. Sources of bias were assessed independently by two reviewers using the Cochrane bias assessment tool for randomized controlled trials (RCTs) and Newcastle-Ottawa Quality Assessment Scale for non-RCTs. Data were synthesized using a level of evidence approach. Meta-analyses were deemed to be inappropriate due to the heterogeneity of study designs, measurement tools and interventions. Five studies were included: one RCT; two pilot RCTs and two samples of convenience. A total of 262 people with RA were included. Interventions used were difficult to assess due to the heterogeneity of study designs and the inclusion of two using different types of yoga as an intervention. Different sleep outcome measures were used thus, it was not feasible to pool results. Studies had a high risk of bias. This review could find no consistent or conclusive evidence on whether exercise impacts on sleep in people who have rheumatoid arthritis, therefore no firm conclusions can be made. However, there is some indication that exercise may have positive benefits on sleep in people who have rheumatoid arthritis. Further studies with improved study designs, using subjective and objective measures, are needed.

Abstract
AIM To revaluate through re-audit the technical quality of undergraduate nonsurgical root canal treatment (RCTx) in a dental teaching hospital as a result of recommended changes to teaching practices. METHODOLOGY The technical quality of undergraduate RCTx was evaluated radiographically after educational changes and the mandatory introduction of new technologies (nickel-titanium files, apex locators, greater taper gutta-percha points) in 182 root canals. Evaluation was based on four criteria: presence of voids, root canal filling termination (0-2 mm of radiographic apex), all roots filled and the prepared canal contained the original anatomy. Chi-squared analysis was used to determine statistically significant improvements in quality between the respective audits (P < 0.05). RESULTS Twenty-three of the 40 canals in single-rooted teeth (57.5%) and 68 of the 129 (52.7%) canals in multirooted teeth analysed had an acceptable root filling. This compared with 48% of canals in single-rooted teeth and 38% of canals in multirooted teeth in the original audit. Specifically, the frequency of root canal voids and unsatisfactory apical root filling termination were reduced in multirooted teeth by 23% and 14% and in single-rooted teeth by 11% and 12%, respectively, compared with the original audit. When multirooted teeth were taken as one unit, 45.2% were considered to be acceptable, significantly better than the 18.8% multirooted teeth in the original audit (P = 0.042). Deviations from the canal anatomy on radiographic examination were rare findings in both audits. CONCLUSIONS Changes to endodontic teaching practices significantly improved the technical standards of undergraduate root filling in multirooted teeth. The regular auditing of undergraduate teaching practice is necessary to inform current teaching, instigate change and improve standards.

Abstract
'Morph' means to change gradually and completely from one thing into another usually in a way that is surprising or seems magical. How can cytotechnology education be morphed into an expanded curriculum to teach new skills for advanced practice? The challenges cytotechnology programmes are facing today are many. The biggest of these challenges is the decreasing volume of Pap tests. Pap tests have been our 'bread and butter' throughout history; however, advances in health care and technology are inevitable, thus requiring changes in our educational practices. While these challenges seem insurmountable, we have the ability to expand the field of cytotechnology by taking advantage of existing opportunities. One example of these opportunities is performing rapid on site evaluation (ROSE) for specimen adequacy and perhaps taking it one step further by giving a preliminary diagnosis as a billable procedure. Now is the time to take gradual steps towards change in the current practice of cytotechnology. Let's join together and make the journey surprising and magical.

Variation in population levels of physical activity in European adults according to cross-European studies: a systematic literature review within DEDIPAC. Int J Behav Nutr Phys Act 2016; 13:72. [PMID: 27350359 PMCID: PMC4924233 DOI: 10.1186/s12966-016-0398-2] [Citation(s) in RCA: 67] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2015] [Accepted: 06/11/2016] [Indexed: 01/26/2023] Open
Abstract
BACKGROUND Physical inactivity is a well-known public health risk that should be monitored at the population level. Physical activity levels are often surveyed across Europe. This systematic literature review aims to provide an overview of all existing cross-European studies that assess physical activity in European adults, describe the variation in population levels according to these studies, and discuss the impact of the assessment methods. METHODS Six literature databases (PubMed, EMBASE, CINAHL, PsycINFO, SportDiscus and OpenGrey) were searched, supplemented with backward- and forward tracking and searching authors' and experts' literature databases. Articles were included if they reported on observational studies measuring total physical activity and/or physical activity in leisure time in the general population in two or more European countries. Each record was reviewed, extracted and assessed by two independent researchers and disagreements were resolved by a third researcher. The review protocol of this review is registered in the PROSPERO database under registration number CRD42014010334. RESULTS Of the 9,756 unique identified articles, twenty-five were included in this review, reporting on sixteen different studies, including 2 to 35 countries and 321 to 274,740 participants. All but two of the studies used questionnaires to assess physical activity, with the majority of studies using the IPAQ-short questionnaire. The remaining studies used accelerometers. The percentage of participants who either were or were not meeting the physical activity recommendations was the most commonly reported outcome variable, with the percentage of participants meeting the recommendations ranging from 7% to 96% across studies and countries. CONCLUSIONS The included studies showed substantial variation in the assessment methods, reported outcome variables and, consequently, the presented physical activity levels. Because of this, absolute population levels of physical activity in European adults are currently unknown. However, when ranking countries, Ireland, Italy, Malta, Portugal, and Spain generally appear to be among the less active countries. Objective data of adults across Europe is currently limited. These findings highlight the need for standardisation of the measurement methods, as well as cross-European monitoring of physical activity levels.

Variation in population levels of physical activity in European children and adolescents according to cross-European studies: a systematic literature review within DEDIPAC. Int J Behav Nutr Phys Act 2016; 13:70. [PMID: 27350134 PMCID: PMC5399406 DOI: 10.1186/s12966-016-0396-4] [Citation(s) in RCA: 112] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2015] [Accepted: 06/11/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Regular physical activity is associated with physical, social and mental health benefits, whilst insufficient physical activity is associated with several negative health outcomes (e.g. metabolic problems). Population monitoring of physical activity is important to gain insight into prevalence of compliance to physical activity recommendations, groups at risk and changes in physical activity patterns. This review aims to provide an overview of all existing studies that measure physical activity in youth, in cross-European studies, to describe the variation in population levels of physical activity and to describe and define challenges regarding assessment methods that are used. METHODS A systematic search was performed on six databases (PubMed, EMBASE, CINAHL, PsycINFO, SportDiscus and OpenGrey), supplemental forward- and backward tracking was done and authors' and experts' literature databases were searched to identify relevant articles. Journal articles or reports that reported levels of physical activity in the general population of youth from cross-European studies were included. Data were reviewed, extracted and assessed by two researchers, with disagreements being resolved by a third researcher. The review protocol of this review is published under registration number CRD42014010684 in the PROSPERO database. RESULTS The search resulted in 9756 identified records of which 30 articles were included in the current review. This review revealed large differences between countries in prevalence of compliance to physical activity recommendations (i.e. 60 min of daily moderate- to vigorous-intensity physical activity (MVPA)) measured subjectively (5-47%) and accelerometer measured minutes of MVPA (23-200 min). Overall boys and children were more active than girls and adolescents. Different measurement methods (subjective n = 12, objective n = 18) and reported outcome variables (n = 17) were used in the included articles. Different accelerometer intensity thresholds used to define MVPA resulted in substantial differences in MVPA between studies conducted in the same countries when assessed objectively. CONCLUSIONS Reported levels of physical activity and prevalence of compliance to physical activity recommendations in youth showed large variation across European countries. This may reflect true variation in physical activity as well as variation in assessment methods and reported outcome variables. Standardization across Europe, of methods to assess physical activity in youth and reported outcome variables is warranted, preferably moving towards a pan-European surveillance system combining objective and self-report methods.

Abstract
BACKGROUND Sedentary behaviour is increasingly recognized as a public health risk that needs to be monitored at the population level. Across Europe, there is increasing interest in assessing population levels of sedentary time. This systematic literature review aims to provide an overview of all existing cross-European studies that measure sedentary time in adults, to describe the variation in population levels across these studies and to discuss the impact of assessment methods. METHODS Six literature databases (PubMed, EMBASE, CINAHL, PsycINFO, SportDiscus and OpenGrey) were searched, supplemented with backward- and forward tracking and searching authors' and experts' literature databases. Articles were included if they reported on observational studies measuring any form of sedentary time in the general population in two or more European countries. Each record was reviewed, extracted and assessed by two independent researchers, and disagreements were resolved by a third researcher. The review protocol of this review is registered in the PROSPERO database under registration number CRD42014010335. RESULTS Of the 9,756 unique articles that were identified in the search, twelve articles were eligible for inclusion in this review, reporting on six individual studies and three Eurobarometer surveys. These studies represented 2 to 29 countries, and 321 to 65,790 participants. Eleven studies focused on total sedentary time, while one studied screen time. The majority of studies used questionnaires to assess sedentary time, while two studies used accelerometers. Total sedentary time was reported most frequently and varied from 150 (median) to 620 (mean) minutes per day across studies and countries. CONCLUSIONS One third of European countries were not included in any of the studies. Objective measures of European adults are currently limited, and most studies used single-item self-reported questions without assessing sedentary behaviour types or domains. Findings varied substantially between studies, meaning that population levels of sedentary time in European adults are currently unknown. In general, people living in northern Europe countries appear to report more sedentary time than southern Europeans. The findings of this review highlight the need for standardisation of the measurement methods and the added value of cross-European surveillance of sedentary behaviour.

Variation in population levels of sedentary time in European children and adolescents according to cross-European studies: a systematic literature review within DEDIPAC. Int J Behav Nutr Phys Act 2016; 13:69.

Abstract
BACKGROUND A high amount of sedentary time has been proposed as a risk factor for various health outcomes in adults. While the evidence is less clear in children and adolescents, monitoring sedentary time is important to understand the prevalence rates and how this behaviour varies over time and by place. This systematic literature review aims to provide an overview of existing cross-European studies on sedentary time in children (0-12y) and adolescents (13-18y), to describe the variation in population levels of sedentary time, and to discuss the impact of assessment methods. METHODS Six literature databases were searched (PubMed, EMBASE, CINAHL, PsycINFO, SportDiscus and OpenGrey), followed by backward- and forward tracking and searching authors' and experts' literature databases. Included articles were observational studies reporting on levels of sedentary time in the general population of children and/or adolescents in at least two European countries. Population levels were reported separately for children and adolescents. Data were reviewed, extracted and assessed by two researchers, with disagreements being resolved by a third researcher. The review protocol is published under registration number CRD42014013379 in the PROSPERO database. RESULTS Forty-two eligible articles were identified, most were cross-sectional (n = 38). The number of included European countries per article ranged from 2 to 36. Levels of sedentary time were observed to be higher in East-European countries compared to the rest of Europe. There was a large variation in assessment methods and reported outcome variables. The majority of articles used a child-specific questionnaire (60%). Other methods included accelerometers, parental questionnaires or interviews and ecological momentary assessment tools. Television time was reported as outcome variable in 57% of included articles (ranging from a mean value of 1 h to 2.7 h in children and 1.3 h to 4.4 h in adolescents), total sedentary time in 24 % (ranging from a mean value of 192 min to 552 min in children and from 268 min to 506 min in adolescents). CONCLUSION A substantial number of published studies report on levels of sedentary time in children and adolescents across European countries, but there was a large variation in assessment methods. Questionnaires (child specific) were used most often, but they mostly measured specific screen-based activities and did not assess total sedentary time. There is a need for harmonisation and standardisation of objective and subjective methods to assess sedentary time in children and adolescents to enable comparison across countries.

Profile of Frequent Attenders to a Dublin Inner City Emergency Department. IRISH MEDICAL JOURNAL 2016; 109:389. [PMID: 27685483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 06/06/2023]
Abstract
A retrospective review of the demographics, co-morbidities and substance misuse of the 20 most frequent presenters to the Mater Misericordiae University Hospital emergency department during 2014 was carried out in an attempt to better understand the epidemiology of their presentations. Eighty-five percent were male and 15% female (p<0.001). The average age was 40.6 years with a median 38.5 years. All were unemployed and 7 (35%) had no fixed abode. Thirteen patients (65%) lived an average of 4.5 kilometres from the ED. In this study the presence of a mental illness, homelessness, alcohol or drug misuse were associated with significantly higher attendance rates (p=0.001, p<0.001, p<0.05, p<0.001 respectively). Early identification of these patients and targeting them for effective case-based community-led treatment strategies could improve their quality of life, decrease their cost of care and ultimately lead to more effective utilisation of our already overburdened emergency departments.

Abstract
Objectives: This study aimed firstly to investigate the feasibility of the study protocol and outcome measures, secondly to obtain data in order to inform the power calculations for a larger randomised controlled trial, and finally to investigate if whole-body vibration (WBV) is more effective than the same duration and intensity of standard exercises (EXE) in people with Multiple Sclerosis (PwMS). Design: Randomised controlled feasibility study. Setting: Outpatient MS centre. Subjects: Twenty seven PwMS (age mean (SD) 48.1 (11.2)) with minimal gait impairments. Interventions: Twelve weeks of WBV or standard EXE, three times weekly. Main measures: Participants were measured with isokinetic muscle strength, vibration threshold, Timed Up and Go test (TUG), Mini-BESTest (MBT), 6 Minute Walk test (6MWT), Multiple Sclerosis Impact Scale 29 (MSIS 29), Modified Fatigue Impact Scale (MFIS) and Verbal Analogue scale for sensation (VAS) pre and post 12 week intervention. Results: WBV intervention was found feasible with low drop-out rate (11.1%) and high compliance (90%). Data suggest that a sample of 52 in each group would be sufficient to detect a moderate effect size, with 80% power and 5% significance for 6 minute walk test. Large effect sizes in favour of standard exercise were found for vibration threshold at 5th metatarsophalangeal joint and heel ( P=0.014, r= 0.5 and P=0.005, r=0.56 respectively). No between group differences were found for muscle strength, balance or gait ( P>0.05). Conclusions: Data suggest that the protocol is feasible, there were no adverse effects. A trial including 120 people would be needed to detect an effect on walking endurance.

Treadmill stimulation improves newborn stepping. Dev Psychobiol 2015; 57:247-54.

Abstract
To shed further light on infant stepping, we investigated whether newborns could step on a treadmill and adapt their steps to graded velocities. Twenty-one newborns (mean = 3 days) were supported for 60 s trials on a treadmill that was static or moved at 13.4, 17.2, or 23.4 cm/s. Video analysis revealed that newborns made more real steps than in-place "pumps" on the moving treadmill than on the static treadmill and made more real steps at 17.2 than 23.4 cm/s. While the treadmill had no effect on arousal, stepping increased and showed higher quality and coordination across conditions when infants were crying. These findings suggest that treadmill interventions currently used to promote the development of independent locomotion in infants at risk of delay could begin at birth. Further investigation is needed to establish the optimal conditions for newborn treadmill stepping and to specify how arousal affects step rate, quality, and coordination.

Abstract
To address major societal challenges and enhance cooperation in research across Europe, the European Commission has initiated and facilitated 'joint programming'. Joint programming is a process by which Member States engage in defining, developing and implementing a common strategic research agenda, based on a shared vision of how to address major societal challenges that no Member State is capable of resolving independently. Setting up a Joint Programming Initiative (JPI) should also contribute to avoiding unnecessary overlap and repetition of research, and enable and enhance the development and use of standardised research methods, procedures and data management. The Determinants of Diet and Physical Activity (DEDIPAC) Knowledge Hub (KH) is the first act of the European JPI 'A Healthy Diet for a Healthy Life'. The objective of DEDIPAC is to contribute to improving understanding of the determinants of dietary, physical activity and sedentary behaviours. DEDIPAC KH is a multi-disciplinary consortium of 46 consortia and organisations supported by joint programming grants from 12 countries across Europe. The work is divided into three thematic areas: (I) assessment and harmonisation of methods for future research, surveillance and monitoring, and for evaluation of interventions and policies; (II) determinants of dietary, physical activity and sedentary behaviours across the life course and in vulnerable groups; and (III) evaluation and benchmarking of public health and policy interventions aimed at improving dietary, physical activity and sedentary behaviours. In the first three years, DEDIPAC KH will organise, develop, share and harmonise expertise, methods, measures, data and other infrastructure. This should further European research and improve the broad multi-disciplinary approach needed to study the interactions between multilevel determinants in influencing dietary, physical activity and sedentary behaviours. Insights will be translated into more effective interventions and policies for the promotion of healthier behaviours and more effective monitoring and evaluation of the impacts of such interventions.

The phenology of Rubus fruticosus in Ireland: herbarium specimens provide evidence for the response of phenophases to temperature, with implications for climate warming. INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2012; 56:1103-1111. [PMID: 22382508 DOI: 10.1007/s00484-012-0524-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/28/2011] [Revised: 01/24/2012] [Accepted: 01/26/2012] [Indexed: 05/31/2023]
Abstract
To date, phenological research has provided evidence that climate warming is impacting both animals and plants, evidenced by the altered timing of phenophases. Much of the evidence supporting these findings has been provided by analysis of historic records and present-day fieldwork; herbaria have been identified recently as an alternative source of phenological data. Here, we used Rubus specimens to evaluate herbaria as potential sources of phenological data for use in climate change research and to develop the methodology for using herbaria specimens in phenological studies. Data relevant to phenology (collection date) were recorded from the information cards of over 600 herbarium specimens at Ireland's National Herbarium in Dublin. Each specimen was assigned a score (0-5) corresponding to its phenophase. Temperature data for the study period (1852 - 2007) were obtained from the University of East Anglia's Climate Research Unit (CRU); relationships between temperature and the dates of first flower, full flower, first fruit and full fruit were assessed using weighted linear regression. Of the five species of Rubus examined in this study, specimens of only one (R. fruticosus) were sufficiently abundant to yield statistically significant relationships with temperature. The results revealed a trend towards earlier dates of first flower, full flower and first fruit phenophases with increasing temperature. Through its multi-phenophase approach, this research serves to extend the most recent work-which validated the use of herbaria through use of a single phenophase-to confirm herbarium-based research as a robust methodology for use in future phenological studies.

Abstract
Following eccentric exercise, increases in muscle length alter the length-tension relation of skeletal muscle. However, its unclear if this change occurs during eccentric exercise. Therefore, 70 eccentric actions of the knee extensors of one leg (with superimposed electrical stimulation) were performed at 100°/s, from full extension to full flexion. Angle-specific eccentric force was recorded throughout. Force decreased at all angles although this was non-uniform. At 70°, force decreased by 25%, whereas at 130°, force decreased by 41%. Initial peak force was recorded at 100° (590 ± 232 N); the exercise bout induced a 21% decrease in peak force and a 10° shift in the position of peak force production to 90°. The rightward shift in the muscle length-tension relation thus occurred during eccentric exercise, where greater force loss at short muscle lengths suggested an eccentric-induced over-stretching of sarcomeres.
