[Cardiovascular response to sympathetic stimulation in normal subjects with or without familial hypertension].
1990
The aim of our study was to seek out a possible different reactiveness to cardiovascular stimulation tests among normotensives with and without positive family history of essential hypertension. We have studied about 200 inhabitants of Ustica and 49 medicine students, all normotensives according to the World Health Organization and the Joint National Committee criteria. In an isolated room and in a supine position, blood pressure (BP) and heart rate were measured every 30 s for 15 min with an automatic sphygmomanometer. Averages of last 4 measurements were considered baseline values. Then we have carried out mental stress (MS), handgrip and active orthostatism test (AO) in the inhabitants o…
EMG-Assisted Muscle Force Driven Finite Element Model of the Knee Joint with Fibril-Reinforced Poroelastic Cartilages and Menisci.
2019
Abnormal mechanical loading is essential in the onset and progression of knee osteoarthritis. Combined musculoskeletal (MS) and finite element (FE) modeling is a typical method to estimate load distribution and tissue responses in the knee joint. However, earlier combined models mostly utilize static-optimization based MS models and muscle force driven FE models typically use elastic materials for soft tissues or analyze specific time points of gait. Therefore, here we develop an electromyography-assisted muscle force driven FE model with fibril-reinforced poro(visco)elastic cartilages and menisci to analyze knee joint loading during the stance phase of gait. Moreover, since ligament pre-st…
Importance of Patella, Quadriceps Forces, and Depthwise Cartilage Structure on Knee Joint Motion and Cartilage Response During Gait
2015
In finite-element (FE) models of the knee joint, patella is often omitted. We investigated the importance of patella and quadriceps forces on the knee joint motion by creating an FE model of the subject's knee. In addition, depthwise strains and stresses in patellar cartilage with different tissue properties were determined. An FE model was created from subject's magnetic resonance images. Knee rotations, moments, and translational forces during gait were recorded in a motion laboratory and used as an input for the model. Three material models were implemented into the patellar cartilage: (1) homogeneous model, (2) inhomogeneous (arcadelike fibrils), and (3) random fibrils at the superficia…
Non-invasive determination of cartilage thickness throughout joint surfaces using magnetic resonance imaging.
1997
Abstract Data on articular cartilage thickness in the living are important for the design of computer models, aimed at preoperatively assessing the effect of surgical procedures on joint contact and load transmission, and for the calculation of cartilage material properties from its deformational behavior as determined during arthroscopy. A non-invasive method for measuring cartilage thickness in living subjects is, however, not available. A technique based on magnetic resonance imaging has therefore been tested for assessing articular cartilage thickness throughout joint surfaces. The accuracy is determined by comparing cartilage thickness maps obtained from three patellar specimens with a…
Correlative gene expression pattern linking RNF123 to cellular stress–senescence genes in patients with depressive disorder: Implication of DRD1 in t…
2013
Abstract Background The expression level of the RNF1213 gene in blood cells has been identified as a disease risk marker, more than ten years before the diagnosis of depression ( Glahn et al., 2012 ). To explore the status of this gene in the acute depressive state we have quantified the expression of RNF123 in the blood leukocytes ( N =17), dorsolateral prefrontal and cingulate cortex ( N =24) of patients with diagnosed depression and of matched controls. We have measured the expression of the DRD1 gene as a “neuronal probe”. We have also quantified the mRNA of six genes previously identified as markers of the biopsychological stress associated with major depression: FOS, DUSP1, OGG1, STMN…
Coping with an acute psychosocial challenge: behavioral and physiological responses in young women.
2014
Despite the relevance of behavior in understanding individual differences in the strategies used to cope with stressors, behavioral responses and their relationships with psychobiological changes have received little attention. In this study on young women, we aimed at analyzing the associations among different components of the stress response and behavioral coping using a laboratory psychosocial stressor. The Ethological Coding System for Interviews, as well as neuroendocrine, autonomic and mood parameters, were used to measure the stress response in 34 young women (17 free-cycling women in their early follicular phase and 17 oral contraceptive users) subjected to the Trier Social Stress …
A longitudinal study of psychosocial distress in breast cancer: prevalence and risk factors.
2011
This longitudinal study was conducted among 102 women with non-metastasic breast cancer to identify the time evolution and prevalence of distress at specific times through diagnosis and treatment of disease: preliminary diagnosis, surgery, definitive diagnosis and chemotherapy. Additionally, the study aimed to examine the role of demographic, medical and psychosocial factors on distress. The results indicated that prevalence of distress was higher at initial diagnosis (25%) than the following time points (approximately 17%). The differences inter-individuals in the levels of distress were observed over the four assessments. No relation between distress and demographic and medical factors wa…
Early rehabilitation of cancer patients—An individual randomized stepped‐care stress‐management intervention
2018
Objective To evaluate the effects of an individual stepped-care stress-management intervention for cancer patients on cancer-related stress reactions (intrusion/avoidance), and secondarily on psychological distress (anxiety/depression) and emotional reactivity (impatience/hostility). Methods Consecutively 291 cancer patients were included in a randomized controlled intervention study. Patients randomized to the intervention who did not report clinically significant stress levels (n = 72) after the first counseling session participated in only one counseling session and a follow-up (Step 1). The remaining patients (n = 66) received an additional three to eight sessions, depending on individu…
Cancer Patients' Long-term Experiences of Participating in a Comprehensive Lifestyle Intervention Study While Receiving Chemotherapy.
2018
Background Lifestyle interventions seem promising with regard to cancer patients' potential for physical and psychological health benefits and as an empowerment tool. Nevertheless, there is a lack of knowledge concerning cancer patients' longer-term experiences of participating in comprehensive lifestyle interventions. Objective The aim of this study was to explore cancer patients' long-term experiences of participating in a 12-month individualized comprehensive lifestyle intervention study focusing on physical activity, diet, smoking cessation, and stress management while receiving curative or palliative chemotherapy. Methods A qualitative design with semistructured interviews of 7 curativ…
Emotional suppression and breast cancer: validation research on the Spanish Adaptation of the Courtauld Emotional Control Scale (CECS).
2010
Emotional suppression has played an important role in the research on psychosocial factors related to cancer. It has been argued to be an important psychological factor predicting worse psychosocial adjustment in people with cancer and it may mediate health outcomes. The reference instrument in the research on emotional suppression is the Courtauld Emotional Control Scale (CECS). The present study analysed construct validity of a new Spanish adaptation of the CECS in a sample of 175 breast cancer patients. The results confirmed the proposal by Watson and Greer claiming that the CECS is composed of three subscales that measure different dimensions, but not independent, from emotional control…
