Changes in catastrophizing and kinesiophobia are predictive of changes in disability and pain after treatment in patients with anterior knee pain
2014
Purpose. The purpose of the study was to investigate if changes in psychological variables are related to the outcome in pain and disability in patients with chronic anterior knee pain. Methods. A longitudinal observational study on 47 patients with chronic anterior knee pain was performed in a secondary healthcare setting. Pain was measured with the visual analogue scale and disability with the Lysholm scale. The psychological variables, such as anxiety, depression, pain coping strategies, catastrophizing and fear to movement beliefs, were studied by using self-administered questionnaires. Results. Among the pain coping strategies, only the catastrophizing subscale showed a significant red…
Patients with soft tissue sarcoma comprise a higher probability of comorbidities than cancer-free individuals. A secondary data analysis.
2016
Soft tissue sarcoma comprises a heterogeneous group of solid malignant tumours. Comorbidities are important prognostic factors for survival and adversely impact quality of life. We examined the complex relationship between soft tissue sarcoma and comorbidities over time in a large population-based sample. The study uses routine data from the German statutory healthcare system (n = 2,615,865). Case identification of soft tissue sarcoma and comorbid diseases was based on ICD-10 codes and diagnostic modifiers. Uni- and multivariate regression models were used to obtain risk estimates for chronic somatic and mental comorbidities in soft tissue sarcoma patients compared to a cancer-free control …
Auditory event-related potentials (P300) in epileptic patients.
2001
Auditory event-related potentials (AERPs) were recorded during an auditory oddball paradigm in 108 epileptics and in 32 healthy controls. P300 latency varied in relationship with age only in controls. Symptomatic epileptics had significantly prolonged P300 mean latency compared to those without detectable brain lesion(s) on MR scan. Moreover, these latter patients were compared on the basis of epilepsy duration, type of seizure, seizure frequency and antiepileptic treatment; the application of a multiple regression model showed a significant relationship between P300 latency prolongation and epilepsy duration, seizure frequency and polytherapy.
Ischemic-type biliary lesions after liver transplantation: a retrospective analysis of risk factors and outcome.
2013
BACKGROUND Ischemic-type biliary lesions (ITBL) are the most troublesome complications after liver transplantation. Their cause remains unknown and, although some risk factors have been identified, results from different research groups are often conflicting. The goal of this study was to investigate potential risk factors for ITBL. METHODS 565 transplantations performed between September 1997 and August 2010 were identified and divided into two cohorts: 77 in which the patient developed ITBL and 488 in which no ITBL occurred. The following factors were analyzed: donor age, patient Child-Pugh score, cold ischemia time, total ischemia time, type of perfusion solution, shipped versus non-ship…
Depression and pain: primary data and meta-analysis among 237 952 people across 47 low- and middle-income countries
2017
BackgroundDepression and pain are leading causes of global disability. However, there is a paucity of multinational population data assessing the association between depression and pain, particularly among low- and middle-income countries (LMICs) where both are common. Therefore, we investigated this association across 47 LMICs.MethodsCommunity-based data on 273 952 individuals from 47 LMICs were analysed. Multivariable logistic and linear regression analyses were performed to assess the association between the International Classification of Diseases, 10th Revision depression/depression subtypes (over the past 12 months) and pain in the previous 30 days based on self-reported data. Country…
Texture analysis in susceptibility-weighted imaging may be useful to differentiate acute from chronic multiple sclerosis lesions.
2020
To evaluate the diagnostic performance of texture analysis (TA) applied on non-contrast-enhanced susceptibility-weighted imaging (SWI) to differentiate acute (enhancing) from chronic (non-enhancing) multiple sclerosis (MS) lesions. We analyzed 175 lesions from 58 patients with relapsing-remitting MS imaged on a 3.0 T MRI scanner and applied TA on T2-w and SWI images to extract texture features. We evaluated the presence or absence of lesion enhancement on T1-w post-contrast images and performed a computational statistical analysis to assess if there was any significant correlation between the texture features and the presence of lesion activity. ROC curves and leave-one-out cross-validation…
Influence of sociodemographic factors upon pain intensity in patients with temporomandibular joint disorders seen in the primary care setting
2012
Objective: A study is made of the influence of gender, educational level, marital status, income, social support, and perceived general and oral health upon pain intensity in a sample of patients with temporomandibular joint disorders (TMJD) explored in primary care (AP). Design: A review was made of 899 patients from Córdoba Healthcare District (Spain) referred to the primary care TMJD Unit by their primary care physician and/or dentist. Of these subjects, 151 failed to meet the inclusion criteria. The remaining 748 subjects were explored according to the corresponding research diagnostic criteria (RDC/TMJD). A bivariate analysis was made the association of pain intensity to the demographi…
Lifestyle habits and depressive symptoms in Norwegian adolescents: a national cross-sectional study
2021
Abstract Background This study’s purpose was to examine the association between a broad range of lifestyle habits and depressive symptoms in Norwegian adolescents. Methods This study was based on national, self-reported, cross-sectional data from the Ungdata Surveys, conducted in 2017–2019. The target group comprised 244,250 adolescents (ages 13–19). Binominal logistic regression was used to analyse the association between lifestyle habits (physical activity, social media use, gaming, dietary habits, smoking, smokeless tobacco, alcohol intoxication) and depressive symptoms. The outcome measure was defined as a high level of depressive symptoms (≥80th percentile). Separate analyses were perf…
Long-term effects of a multidisciplinary treatment of uncomplicated obesity on carotid intima-media thickness
2011
Obesity is associated with well-known cardiovascular risk factors and a lower life expectancy. This study investigated whether nonoperative nutritional treatment of obesity without comorbidities influenced the carotid intima-media thickness (c-IMT) in the long run. Fifty-four subjects of an original cohort of 251 subjects were re-evaluated 10 years after a medical nutritional treatment (MNT) with cognitive-behavioral approach for uncomplicated obesity. Forty subjects were classified as failure (10-year body weight change >0.5 kg) and 14 (body weight change ≤0.5 kg) as a success of the MNT. Ten years after MNT, c-IMT significantly increased (0.06 ± 0.02 mm; P = 0.004) in the failure group an…
The 12-month prevalence of depression and health care utilization in the general population of Latvia.
2017
Abstract Background This cross-sectional study aims to assess the 12-month prevalence of major and minor depression in the Latvian population, and to evaluate associated health care utilization. Methods Trained interviewers conducted face-to-face interviews with a multistage stratified probability sample of the Latvian general population, ages 15–64 (n=3003). Participants were interviewed using the depression module of the Mini International Neuropsychiatric Interview. Self-reported health care utilization and somatic illness were also assessed. Multinomial logistic regressions were applied. Results The 12-month prevalence of major depression was 7.9% (95%CI 7.0–8.9), while for minor depres…
