Colony-Stimulating Factor-1
2015
A noninvasive means to predict the onset and recurrence of lupus nephritis (LN) before overt renal injury is needed to optimize and individualize treatment. Colony-stimulating factor-1 (CSF-1) is expressed by kidney tubules at the onset of LN, increases with disease progression, and spills into the circulation in lupus-prone mice. We tested the hypothesis that amplified expression of CSF-1 detected in the serum or urine correlates with intrarenal CSF-1 expression and histopathology (increased macrophage accumulation, activity indices) and clinical kidney disease activity and predicts the onset and recurrence of nephritis in patients with systemic lupus erythematosus (SLE). We found increase…
Effects of 12-wk eccentric calf muscle training on muscle-tendon glucose uptake and SEMG in patients with chronic Achilles tendon pain
2014
High-load eccentric exercises have been a key component in the conservative management of chronic Achilles tendinopathy. This study investigated the effects of a 12-wk progressive, home-based eccentric rehabilitation program on ankle plantar flexors' glucose uptake (GU) and myoelectric activity and Achilles tendon GU. A longitudinal study design with control ( n = 10) and patient ( n = 10) groups was used. Surface electromyography (SEMG) from four ankle plantar flexors and GU from the same muscles and the Achilles tendon were measured during submaximal intermittent isometric plantar flexion task. The results indicated that the symptomatic leg was weaker ( P < 0.05) than the asymptomatic…
Monitoring cognitive changes: Psychometric properties of six cognitive tests
2004
Objectives. Repeated neuropsychological assessments are often used to monitor change in cognitive functioning over time. Thus, knowledge about the reliability and stability of neuropsychological tests and the effects of age and IQ is of paramount importance. In this study we document, for six cognitive tests: test-retest reliabilities, practice effects, reliable change (RC) indices corrected for practice, and the impact of premorbid IQ and age. Design. A sample of 188 normal adults (aged 40-70 years) were administered, on two occasions, one or more of the following tests: the Graded Naming Test (GNT), the Silhouettes Test, two tests of verbal fluency, the Modified Wisconsin Card Sorting Tes…
Patients with minimal hepatic encephalopathy show impaired mismatch negativity correlating with reduced performance in attention tests
2012
Attention deficit is an early event in the cognitive impairment of patients with minimal hepatic encephalopathy (MHE). The underlying mechanisms remain unclear. Mismatch negativity (MMN) is an auditory event-related potential that reflects an attentional trigger. Patients with schizophrenia show impaired attention and cognitive function, which are reflected in altered MMN. We hypothesized that patients with MHE, similarly to those with schizophrenia, should show MMN alterations related with attention deficits. The aims of this work were to assess whether (1) MMN is altered in cirrhotic patients with MHE, compared to those without MHE, (2) MMN changes in parallel with performance in attentio…
Vitamin D and clinical symptoms in First Episode Psychosis (FEP): A prospective cohort study
2019
BACKGROUND: There is a paucity of longitudinal research investigating vitamin D in people with early psychosis.METHOD: Vitamin D levels were measured in 168 patients (64% (n = 108) male, mean age 29.3 (9.8) years) with first episode psychosis (FEP), along with measures of clinical state at baseline and at 12 months follow up. We assessed the a) cross sectional, and; b) longitudinal relationships between continuous and categorical 25-hydroxyvitamin D (25(OH)D) levels and clinical symptoms at first contact for psychosis and at 12 months.RESULTS: In FEP, 80% (n = 134) at baseline, and 76% at 12 months follow up, had suboptimal vitamin D levels (<20 ng/ml). Suboptimal levels of 25 (OH) D at …

Cervical Spondylotic Myelopathy: When and Why the Cervical Corpectomy?
2020
Background: Cervical spondylotic myelopathy (CSM) is a degenerative disease that represents the most common spinal cord disorder in adults. The best treatment option has remained controversial. We performed a prospective study to evaluate the clinical, radiographic, and neurophysiologic outcomes for anterior cervical corpectomy in the treatment of CSM. Methods: From January 2011 to January 2017, 60 patients with CSM were prospectively enrolled in the present study. The patients were divided according to the modified Japanese Orthopaedic Association scale (mJOA) score into 2 groups: group A, patients with mild to moderate CSM (mJOA score ≥13); and group B, patients with severe myelopathy (mJ…
Physical activity, heart rate variability-based stress and recovery, and subjective stress during a 9-month study period.
2017
The aim of this study was to investigate the association between physical activity (PA) and objective heart rate variability (HRV)-based stress and recovery with subjective stress in a longitudinal setting. Working-age participants (n = 221; 185 women, 36 men) were overweight (body mass index, 25.3–40.1 kg/m2) and psychologically distressed (≥3/12 points on the General Health Questionnaire). Objective stress and recovery were based on HRV recordings over 1–3 work days. Subjective stress was assessed with the Perceived Stress Scale and PA level with a questionnaire. Data were collected at three time points: baseline, 10 weeks post intervention, and at the 36-week follow-up. We adopted a late…
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…
