Hormonal Alterations in Victimized Women Explained by Their Hostile Reactions in Coping with Couple Violence
2019
AbstractRecent studies have highlighted the dysregulation of hypothalamic-pituitary-adrenal (HPA) axis activity and its end products, cortisol and dehydroepiandrosterone (DHEA), in women with a history of intimate partner violence (IPV) victimization. These studies analyzed several coping styles, but they neglected to examine the use of violent strategies to confront IPV and the way these strategies affect HPA functioning. This latter proposal would be based on the gender symmetry model of IPV, which sustains that IPV is generally symmetrical, but that women’s violence tends to be a reaction to male violence. Hence, the main objective of the present study was to examine whether women’s viol…
Stability of habitual physical activity and sport participation: a longitudinal tracking study
2007
Although one of the most important aims of physical education and public sport policy is to encourage life-long habitual physical activity, very little is known of the stability or tracking of physical activity. As a part of a larger research project called Cardiovascular Risks in Young Finns, the purpose of the study reported here was to investigate the stability (tracking) of leisure-time physical activity and sport participation at intervals of 3, 6, 9 and 12 years from age 9 to 30. The subjects, chosen by stratified random sample, represent five geographical areas of the country and eight gender-age cohorts (9, 12, 15 and 18 years old in 1980). Physical activity and sport participation …
Cellular-free magnesium depletion in brain and muscle of normal and preeclamptic pregnancy: A nuclear magnetic resonance spectroscopic study
2004
Preeclampsia is a pregnancy disorder of unknown origin, characterized by vasospasm, elevated blood pressure, and increased neuromuscular irritability, features common to syndromes of magnesium deficiency. Evidence of serum and ionized magnesium metabolism disturbances have been observed in women with preeclampsia. This and the therapeutic utility of magnesium in preeclampsia led us to investigate the extent to which an endogenous tissue magnesium deficiency might be present in and contribute to its pathophysiology. We used 31 P nuclear magnetic resonance spectroscopy to noninvasively measure in situ intracellular-free magnesium levels in brain and skeletal muscle of fasting nonpregnant wom…
Middle patellar tendon to posterior cruciate ligament (PT–PCL) and normalized PT–PCL: New magnetic resonance indices for tibial tubercle position in …
2018
BACKGROUND To demonstrate whether the distance between the middle point of the patellar tendon and posterior cruciate ligament (PT-PCL) calculated on a single axial MR image could be an alternative measure to tibial tubercle-PCL (TT-PCL) distance for TT lateralization without the need of imaging processing. To show that normalization of PT-PCL (nPT-PCL) against the maximum diameter of the tibial plateau may help to identify patients with patellar instability (PI). METHODS MR scans of 30 patients (13 females, age 32 ± 13 years) with known PI and 60 patients (31 females, age 39 ± 19 years) with no history of PI were reviewed. Two operators calculated TT-PCL, and PT-PCL nPT-PCL. Intraclass cor…
Functional evaluation of patients with anterior cruciate ligament injury. A transversal analytical study.
2018
Abstract Objective To evaluate, by means of biomechanical analysis, functional alterations of gait and balance of patients with anterior cruciate ligament (ACL) injury. Material and methods Transversal analytical study on 64 people, 27 health subjects and 37 patients with ACL injury. Biomechanical analysis of gait in all individuals was performed by means of four tests: (1) kinematic test, to characterize gait pattern; (2) kinetic test, to characterize forces against the floor, duration of treads, symmetry of both legs, and the reproducibility of the gait; (3) pivot-shift test, to analyze the rotational stability of the knee on the sagittal axis; and (4) equilibrium test. Results Alteration…
Lumbar spine mobility in Marfan syndrome
1993
Low back pain symptoms and lumbar spine mobility were assessed by questionnaires and by clinical and radiological measurements in 32 patients with Marfan syndrome. Frequently occurring low back pain was reported by 19% of the patients, but the disability was slight in all of them. Flexion and extension mobility of the lumbar spine (L1-S1) assessed from radiographs was 59.9 degrees and 13.2 degrees, respectively. Mean lumbar angular mobility between flexion and extension radiographs was 7.4 degrees at L1-2, 13.2 degrees at L2-3, 16.0 degrees at L3-4, 19.3 degrees at L4-5 and 18.3 degrees at L5-S1. No correlation was found between the manual assessment of lumbar segmental instability and radi…
Retrospective review of L3 myelomeningocele in three age groups: should posterolateral iliopsoas transfer still be indicated to stabilize the hip?
2005
The data from 58 hips in 29 myelodysplastic children with L3 paralysis has been reviewed retrospectively. Posterolateral transfer of the iliopsoas (Sharrard technique) was performed on all hips to correct muscle imbalance between 1975 and 1992. The average length of follow-up was 21 years. Preoperatively, 58.6% of the hips were either subluxated or dislocated (these were surgically reduced at the same stage). Radiological assessment revealed that 91.4% of the hips were stable at preschool age and 84.5% in adolescence. Of the patients 86% were functional walkers at preschool age and 75.8% in adolescence. Downward transitions in seven patients were related to the presence of scoliosis, spasti…
Kinematic parameters after tibial nonunion treatment using the Ilizarov method
2021
Abstract Background Analysis of the outcomes of Ilizarov treatment of tibial nonunion shows functional deficits in the lower limbs of some patients. Biomechanical gait parameters are an important measure for assessing musculoskeletal disorder treatments that aim to restore normal gait. The purpose of our study was to compare the kinematic parameters in patients with tibial nonunion treated using the Ilizarov method and those in a control group of healthy volunteers. Methods The study population consisted of 23 patients (age 54.9 ± 16.4 years) who were treated for tibial nonunion using the Ilizarov method, as well as 22 healthy adult controls (age 52.7 ± 10.6 years). Kinematic parameters wer…
Combined aerobic and resistance training decreases inflammation markers in healthy men
2017
Our primary aim was to study the effects of 24 weeks of combined aerobic and resistance training performed on the same day or on different days on inflammation markers. Physically active, healthy young men were randomly divided into three groups that performed: aerobic and resistance training consecutively in the same training session (SS) 2-3 days wk-1 or on alternating days (AD) 4-6 days wk-1 as well as control (C). The total training volume was matched in the training groups. The control group was asked to maintain their habitual physical activity and exercise level. Maximal leg press strength (1RM) and peak oxygen uptake (VO2peak ) were measured. Abdominal fat mass was estimated with du…
Reduced secretion of proinflammatory cytokines of monosodium urate crystal‐stimulated monocytes in chronic renal failure: an explanation for infreque…
2000
In gouty arthritis, monosodium urate (MSU) crystals interact with monocytes and neutrophils to produce inflammatory reactions associated with acute synovitis. In patients with end-stage renal disease (ESRD), gouty arthritis is a rare condition despite often severe hyperuricaemia. We wondered whether differences in the secretion of proinflammatory cytokines by MSU crystal-stimulated monocytes might be one explanation for the low incidence of gouty arthritis in patients with ESRD compared with healthy controls.Thirteen patients with ESRD on intermittent haemodialysis treatment, six patients with chronic renal failure not yet on dialysis, and 15 age- and sex-matched healthy controls were exami…
