Associations of low back pain with neck pain: a study of industrial employees with 5-, 10-, and 28-year follow-ups.
2007
Low back pain (LBP) and neck pain (NP) are common among the adult population but relatively few reports exist on the associations between these. We examined cross-sectional and prospective relationships of LBP with NP in an employee cohort studied repeatedly over 28 years. Locally perceived pain was studied separately from pain with a radiating component. At baseline, adjusted for age, gender, and occupational class, the prevalence ratio (PR) of local NP for those with local LBP was 1.93 (95% CI 1.47–2.54), and for those with radiating LBP 2.16 (1.59–2.94), while the PR of radiating NP for those with local LBP was 1.51 (0.97–2.35) and for those with radiating LBP 3.24 (2.25–4.65). These ass…
Predicting relapse after a first episode of non-affective psychosis: A three-year follow-up study
2011
Preventing relapse during the first years of illness has a critical impact on lifelong outcomes in schizophrenia. A better understanding and improvement in factors which influence relapse should diminish the risk of relapse and consequently improve the outcome of the illness.To identify factors associated with relapse after 3 years of a first episode in a sample of non-affective psychosis patients who are representative of clinical practice in an epidemiological catchment.We analyzed socio-demographic and clinical data from a cohort of patients who were treated in a specialized early intervention service and who were at risk of relapse during a 3-year follow-up. Univariate analyses, logisti…
Endarterectomy Versus Angioplasty in Patients with Symptomatic Severe Carotid Stenosis (EVA-3S) trial: results up to 4 years from a randomised, multi…
2008
Summary Background Carotid stenting is a potential alternative to carotid endarterectomy but whether this technique is as safe as surgery and whether the long-term protection against stroke is similar to that of surgery are unclear. We previously reported that in patients in the Endarterectomy Versus Angioplasty in Patients with Symptomatic Severe Carotid Stenosis (EVA-3S) trial, the rate of any stroke or death within 30 days after the procedure was higher with stenting than with endarterectomy. We now report the results up to 4 years. Methods In this follow-up study of a multicentre, randomised, open, assessor-blinded, non-inferiority trial, we compared outcome after stenting with outcome …
Incidence, risk factors, and outcome of pulmonary invasive fungal disease after respiratory virus infection in allogeneic hematopoietic stem cell tra…
2019
Abstract Background There is growing evidence that community‐acquired respiratory virus (CARV) increases the risk of pulmonary invasive fungal disease (IFD) in the allogeneic hematopoietic stem cell transplantation (allo‐HSCT) setting. To date, there is a lack of knowledge regarding the risk factors (RFs), as well as the most critical period for subsequent onset of IFD after CARV infections in allo‐HSCT recipients. Methods In this prospective longitudinal observational CARV survey, we analyzed the effect of CARV on subsequent IFD development in 287 adult allo‐HSCT recipients diagnosed with 597 CARV episodes from December 2013 to December 2018. Multiplex PCR panel assays were used to test CA…
Endothelial function and other biomarkers of cardiovascular risk in frequent consumers of street food.
2012
Summary Background & aims Street food (SF) is defined as out-of-home food consumption, and generally consists of energy dense meals rich in saturated fats, and poor in fibers, vitamins and anti-oxidants. Though SF consumption may have unfavorable metabolic and cardiovascular effects, its possible association with endothelial function has not been considered. Methods Participants were recruited among those who took part in a previous study of ours, done in Palermo, Italy, which investigated the association between consumption of SF and health in 1002 people. In that study, a score of SF consumption was obtained by categorizing each of ten foods consumed less than or more than once a month (0…
A longitudinal single-center cohort study on the prevalence and risk of accessory saphenous vein reflux after radiofrequency segmental thermal ablati…
2015
Objective Endothermal ablation has become a commonly used technology for occlusion of refluxing great saphenous veins (GSVs). However, the risk for primarily untreated accessory saphenous veins (ASVs) to develop reflux during follow-up has not yet been defined. Here, the prevalence and risk of ASV reflux is explored. Methods During a prospective multicenter cohort study on radiofrequency segmental thermal ablation of refluxing GSVs, the presence and reflux status of ASVs were monitored in 93 legs in a single center. Control examinations were performed after 1 week and at 12, 24, 36, and 48 months. Life-table and multiple regression analyses were used to describe frequency and risk factors f…
Diurnal coupling between testosterone and cortisol from adolescence to older adulthood
2016
The hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes are typically conceptualized as mutually inhibitory systems; however, previous studies have found evidence for positive within-person associations (i.e., coupling) between cortisol and testosterone. One developmental hypothesis is that positive testosterone-cortisol coupling is unique to the adolescent period and that coupling becomes attenuated, or even switches direction, in adulthood. This study used a lifespan sample (N = 292, ages 11 to 88) to test for age-related differences in coupling between cortisol and testosterone in daily life. Participants provided salivary hormone samples at waking, 30 minu…
Trajectories of Blood Pressure Elevation Preceding Hypertension Onset: An Analysis of the Framingham Heart Study Original Cohort
2018
Importance Given that hypertension remains a leading risk factor for chronic disease globally, there are substantial ongoing efforts to define the optimal range of blood pressure (BP). Objective To identify a common threshold level above which BP rise tends to accelerate in progression toward hypertension. Design, Setting, and Participants This longitudinal, community-based epidemiological cohort study of adults enrolled in Framingham, Massachusetts, included 1252 participants (mean [SD] age, 35.3 [2.7] years) from the Framingham Original Cohort, of whom 790 (63.1%) were women. Each participant contributed up to 28 serial examinations of standardized resting BP measurements between 1948 and…
Motor Development and Physical Activity: A Longitudinal Discordant Twin-Pair Study.
2015
ntroduction : Previous longitudinal research suggests that motor proficiency in early life predicts physical activity in adulthood. Familial effects including genetic and environmental factors could explain the association, but no long-term follow-up studies have taken into account potential confounding by genetic and social family background. The present twin study investigated whether childhood motor skill development is associated with leisure-time physical activity levels in adulthood independent of family background. Methods : Altogether, 1550 twin pairs from the FinnTwin12 study and 1752 twin pairs from the FinnTwin16 study were included in the analysis. Childhood motor development wa…
Genetic and Environmental Effects on the Individual Variation and Continuity of Participation in Diverse Physical Activities
2021
INTRODUCTION Participation in diverse physical activities has beneficial health effects. However, little is known on how genetic and environmental factors affect this trait. Thus, we examined to what extent these factors explain participation in diverse leisure-time physical activities from late adolescence to adulthood using a twin study design. METHODS The participants were Finnish twins who reported their participation in diverse leisure-time physical activities at ages 17 (n = 5429) and 34 yr (n = 4246). The number of physical activities engaged in was analyzed using applications of structural linear modeling for twin data. RESULTS On average, the total number of physical activities eng…
