Effect of highly active anti-retroviral therapy and hepatitis C virus co-infection on serum levels of pro-inflammatory and immunoregulatory cytokines…
2006
ABSTRACTThis study aimed to determine the effect of highly active anti-retroviral therapy (HAART) and hepatitis C virus (HCV) co-infection on peripheral levels of interleukin (IL)-2, IL-10, IL-12 (p70), IL-18 and soluble tumour necrosis factor receptor type II (sTNFRII). Serum levels were monitored for a 1-year period in 25 patients infected with human immunodeficiency virus-1 (HIV-1) who were naive for HAART at the initiation of the study, and in four HIV-1-infected long-term non-progressors. Serum levels of both IL-18 and sTNFRII at baseline were significantly higher in HIV-1-infected patients than in controls. Baseline levels of IL-18 and sTNFRII were not significantly different in long-…
Being mindful at work and at home
2020
Although previous research on mindfulness predominantly focused on benefits of mindfulness, this study investigates quantitative and emotional demands as contextual antecedents of mindful awareness and acceptance both in the work and home domains. In addition, we examine goal attainment and satisfaction in the work and home domains as consequences of mindful awareness and acceptance. Results of a diary study across 5 workdays with 2 daily measurement occasions among 233 employees revealed that both in the work and home domains, quantitative demands were positively associated with awareness, but not with acceptance, whereas emotional demands were positively associated with acceptance, but no…
Discovering dynamic task-modulated functional networks with specific spectral modes using MEG.
2019
Efficient neuronal communication between brain regions through oscillatory synchronization at certain frequencies is necessary for cognition. Such synchronized networks are transient and dynamic, established on the timescale of milliseconds in order to support ongoing cognitive operations. However, few studies characterizing dynamic electrophysiological brain networks have simultaneously accounted for temporal non-stationarity, spectral structure, and spatial properties. Here, we propose an analysis framework for characterizing the large-scale phase-coupling network dynamics during task performance using magnetoencephalography (MEG). We exploit the high spatiotemporal resolution of MEG to m…
From "Non-encounters" to autonomic agency. Conceptions of patients with low back pain about their encounters in the health care system.
2018
Low back pain is a considerable health problem which affects people around the world, causing major healthcare costs. The use of qualitative research methods enables us to describe and understand patients' experience of, and attitudes to, healthcare. The aim of the present phenomenographic study was to identify and describe the contextual nature of the conceptions of patients with low back pain of their encounters in the HCS. Seventeen patients with chronic or episodic low back pain classified as "high risk" were interviewed in open recall interviews, using videos of patients' initial physiotherapy sessions that had been recorded previously. The data were analysed using the phenomenographic…
Relationship between mothers' enjoyment and sedentary behavior and physical activity of mother-child dyads using a movement-to-music video program : …
2020
Background: Parental support and participation in physical activity (PA) with children and parents' acting as a role model for less sedentary behaviors (SB) are critical factors for children's healthier lifestyle. The purpose of the study was to assess the relationship between mothers' enjoyment and participants' sedentary behavior (SB) and physical activity (PA) as a secondary analysis of a randomized controlled trial (RCT) using data from Moving Sound RCT in the Pirkanmaa area of Finland. Methods: The participants were 108 mother-child dyads (child age 5-7 years) who completed the eight-week exercise intervention using a movement-to-music video program in their homes. Mothers' enjoyment w…
Similar relative decline in aerobic and anaerobic power with age with in elite endurance and power master athletes of both sexes
2019
Lower physical activity levels in old age are thought to contribute to the age-related decline in peak aerobic and anaerobic power. Master athletes maintain high levels of physical activity with advancing age and endurance or power training may influence the extent to which these physical functions decline with advancing age. To investigate, 37-90-year-old power (n=20, 45% female) and endurance (n=19, 58% female) master athletes were recruited. Maximal aerobic power was assessed when cycling two-legged (VO2 Peak2-leg ) and cycling one-legged (VO2 Peak1-leg ), while peak jumping (anaerobic) power was assessed by a countermovement jump. Men and women had a similar VO2 Peak2-leg (mL·kg-1 ·min-…
The emergence and adaptive use of prestige in an online social learning task
2020
AbstractPrestige-biased social learning occurs when individuals preferentially learn from others who are highly respected, admired, copied, or attended to in their group. This form of social learning is argued to reflect novel forms of social hierarchy in human societies, and, by providing an efficient short-cut to acquiring adaptive information, underpin the cumulative cultural evolution that has contributed to our species’ ecological success. Despite these potentially important consequences, little empirical work to date has tested the basic predictions of prestige-biased social learning. Here we provide evidence supporting the key predictions that prestige-biased social learning is used …
Reoperation Rates Following Instrumented Lumbar Spine Fusion
2018
Study Design. A prospective cohort study. Objective. This study evaluated the cumulative reoperation rate and indications for reoperation following instrumented lumbar spine fusion (LSF). Summary of Background Data. LSF reduces disability and improves health-related quality of life for patients with several spinal disorders. The rate of instrumented LSF has drastically increased over the last few decades. The increased incidence of LSF, however, has led to increased reoperation rates. Methods. The data are based on the prospective LSF database of Tampere University Hospital that includes all elective indications for LSF surgery. A total of 433 consecutive patients (64% women, mean age 62 ye…

Effect of Cardiorespiratory Fitness on Risk of Sudden Cardiac Death in Overweight/Obese Men Aged 42 to 60 Years
2018
The purpose of this study was to examine the subject and combined associations of cardiorespiratory fitness (fitness) and body mass index (BMI) with the risk of sudden cardiac death (SCD) in middle-aged men. This prospective study was based on a population sample of 2,357 men aged 42 to 60 years, who were followed up in the Kuopio Ischemic Heart Disease cohort study. Fitness was directly measured by peak oxygen uptake (VO2peak) during progressive exercise testing to volitional fatigue. Participants were divided into 4 groups (fit-normal weight, unfit-normal weight, fit-overweight/obese, and unfit-overweight/obese) based on the median values of fitness and BMI. A total of 253 (10.7%) SCDs oc…
