Changes in biochemical markers of bone metabolism and BMD during the first year after a hip fracture
Margareta Hedström Kerstin Sjöberg Jan Svensson Eva Brosjö Nils Dalén 《Acta orthopaedica》2013,84(3):248-251
We measured the levels of biochemical markers of bone formation and bone resorption in hip fracture patients preoperatively and after 6 and 12 months. Bone densitometry was done with quantitative computer tomography (QCT), dual-energy X-ray absorptiometry (DXA) and heel ultrasound. After 6 months, the biochemical markers of bone formation and bone resorption had increased. The levels remained high after 1 year and no change occurred between 6 and 12 months. We found no correlations between biochemical bone markers and bone density/ stiffness on admission and change in bone mineral density (BMD) during the first postoperative year, despite the changes in bone markers and bone density. In our opinion, biochemical bone markers can not be used to predict bone loss in the individual patient after a hip fracture. 相似文献

This study reports the possibility of accomplishing a survey in an ordinary psychiatric service organization to identify the children and the adolescents in families with a parent with mental illness and to highlight the number of patients in psychiatric treatment with little or virtually no contact with their minor children. The prevalence of patients being parents to minor children was 36% in the total sample consisting of 137 patients, from both inpatient and outpatient services, participating in the survey. Three of four patients were living together with the children. A higher proportion of patients in the outpatient unit were parents to minor children, and more often lived together with them. There were no differences in prevalence of patients with minor children according to sex or diagnostic subgroup. However, female patients more often and patients with a psychosis diagnosis more seldom had the custody of the children. A majority of the patients had communicated with their children about their own situation, showing that psychiatric patients care a lot about the situation of their children, although, according to the patients, the psychiatric services only take an active part in this information in a minority of the cases. The study may be found to be a basis for inspiring structured interventions and treatments programmes, including the minor children of the adult patients seeking psychiatric treatment. Prevention of mental disorders in the oncoming generation is an important issue for all psychiatric professionals, especially in co-operation between adult and child/adolescent psychiatric services. 相似文献

Objective: The present study reports on the application of a Swedish translation of the audiologist occupational stress questionnaire (AOSQ) on audiologists working in Sweden. The relations between AOSQ scores and perceived effort, perceived rewards, coping strategies at work, demographic variables such as salary, education length, practise length, and practice type were tested. Design: A cross-sectional e-mail survey using the AOSQ, effort-reward imbalance questionnaire, and demographic questions. Study sample: Four-hundred and four Swedish licensed audiologists working with clients. Results: The Swedish AOSQ translation demonstrated high inter-item correlations and high internal consistency. Several stress factors were identified: time spent at work, accountability, leadership at the workplace, paperwork and practice demands, equipment and clinical protocols, own health concerns, and job control. The outcome on the complete AOSQ questionnaire was related to perceived effort, perceived rewards, coping strategies at work, and age. Conclusions: The Swedish AOSQ translation seems to provide a valid measure of occupational stress among audiologists. 相似文献

Research on the sex lives of people with severe mental illness (SMI) most often focuses on dysfunction and the side-effects of medication. We wished to determine how people with SMI experience sex and assess satisfaction with it in a broader evaluation of quality of life. Data were gathered using mixed methods, including a reliable psychometric quality of life instrument, and in-depth interviews. Sex life showed the lowest rating of all quality of life domains, with men indicating lower satisfaction in this area than women. Low satisfaction also correlated with lower scores on the total quality of life index. Sexuality and intimate relations were generally experienced as out of reach or something of secondary importance that had to be controlled, according to many of those suffering from SMI. Programs such as patient disorder-specific or partner assisted interventions, to increase the possibility of sustaining a sex life might need to be added to existing recommendations for people with SMI living in a community. 相似文献

Ninety subjects with DSM-III-R anorexia nervosa were randomly allocated to four treatment options, one inpatient, two outpatient, and one comprising an assessment interview only. Twenty were thus offered a package of outpatient individual and family psychotherapy. At 2-year follow-up, 12 of the 20 were classed as well, or very nearly well, according to operationally defined criteria. Statistically significant improvements over time were obtained for weight, mean body mass index (BMI), and also for psychological, sexual, and socioeconomic adjustments. Weight and BMI changes were significantly better than for the assessment only group, some of whom had received extensive treatment elsewhere. The style of the outpatient therapy and compliance with it are described in some detail and prognostic indicators for the treated and untreated groups presented. Lower weights at presentation and vomiting were associated with poorer outcome, although age and length of history were not. © 1994 by John Wiley & Sons, Inc. 相似文献
