Rehabilitation of home care workers: supportive factors and obstacles prior to disability pension due to musculoskeletal disorders

The aim of this study was to retrospectively explore the prevalence of rehabilitation actions, supportive factors, and obstacles for rehabilitation among home care workers with musculoskeletal disorders, especially focusing on aspects related to occupational rehabilitation. All home care workers in Sweden whose disability pension was approved in 1997 and 1998 because of a musculoskeletal disorder, were selected (n = 373). Data, covering aspects of the rehabilitation process and conditions in working life 5 and 15 years prior to their disability pension, were collected from a questionnaire. The majority considered that the disorder leading to a disability pension was caused by their work, but only one-third of them had their occupational disorder formally approved. Only one-third of the study group received occupational rehabilitation. However, an approved occupational disorder was related to higher prevalence of occupational rehabilitation. In the age group 60–65, few home care workers received rehabilitation. The majority perceived good support from their supervisor and working team, but no support with regard to lowering physical demands. Modification and reduction of physical demands might improve both sustained work ability in home care work and the outcome of the rehabilitation.     

Imaginative ethics – bringing ethical praxis into sharper relief

The empirical basis for this article is threeyears of experience with ethical rounds atUppsala University Hospital. Three standardapproaches of ethical reasoning are examined aspotential explanations of what actually occursduring the ethical rounds. For reasons given,these are not found to be satisfyingexplanations. An approach called ``imaginativeethics', is suggested as a more satisfactoryaccount of this kind of ethical reasoning. Theparticipants in the ethical rounds seem to drawon a kind of moral competence based on personallife experience and professional competence andexperience. By listening to other perspectivesand other experiences related to one particularpatient story, the participants imaginealternative horizons of moral experience andexplore a multitude of values related toclinical practice that might be at stake. Inhis systematic treatment of aesthetics in theCritique of Judgement, Kant made use ofan operation of thought that, if applied toethics, will enable us to be more sensitive tothe particulars of each moral situation. Basedon this reading of Kant, an account ofimaginative ethics is developed in order tobring the ethical praxis of doctors and nursesinto sharper relief. The Hebraic and theHellenic traditions of imagination are used inorder to illuminate some of the experiences ofethical rounds. In conclusion, it is arguedthat imaginative ethics and principle-basedethics should be seen as complementary in orderto endow a moral discourse with ethicalauthority. Kantian ethics will do the job if itis remembered that Kant suggested only amodest, negative role of principle-baseddeliberation.     

Outcome evaluation of a statewide child inpatient mental health unit

OBJECTIVE: To assess the impact of inpatient intervention, provided by a child mental health unit in Victoria, Australia, on a number of key child and family variables. METHOD: Pre-post test design with a four-month follow up was applied to assess changes across time. Twenty-nine parents, 42 teachers, and 37 referrers provided reports on a series of child, parent, and family functioning measures. RESULTS: Significant improvements in child behaviour and functioning, parenting competency and efficacy, parenting practices, and reduced parental depression were observed over time. Changes in family functioning scores were not significant; however, univariate analysis indicated improvements in two individual subscales. CONCLUSIONS: There is a lack of studies of the outcome of inpatient interventions of children in psychiatric settings. However, as shown in the present study, improvements in functioning can be detected and obtained with short-term interventions that focus on both children and families. Methodological shortcomings (i.e. absence of comparison groups) and lack of specificity in intervention variables, however, are difficulties yet to be overcome in evaluation research of inpatient treatment.     

Functional evaluation of cerebral microembolization in the rat

This study investigates the effects of cerebral microembolism on motor performance and risk assessment behavior in the rat. Cerebral infarcts were produced in rats by injecting small plastic beads into the left heart ventricle under short-acting anesthesia. The functional outcome was tested 24 h later by subjecting the animals to a series of consecutive behavioral tests. Thereafter, the rats were anesthetized and underwent magnetic resonance imaging. On average about seven infarcts per brain were found. The volume of the individual infarcts was largest in the hippocampus (mean=4.26 mm(3)) and smallest in the white matter (mean=0.83 mm(3)). Embolized animals performed spontaneous and evident locomotion. The activity was, however, significantly decreased compared to rats treated with vehicle. More specific tests for motor ability revealed reduced gait capacity and muscular strength. A significant relationship was found between behaviors reflecting motor ability and the total volume of infarcted tissue in the brain stem, cortex and cerebellum. Also the behavioral profile of risk and benefit assessment was found to be altered by the microembolization. It is concluded that the combination of the microembolization method and behavioral tests provides a valuable tool for further studies of the pathophysiology of, and potential treatment for, cerebral infarction.     

Active decay of composite excitatory postsynaptic potentials in hippocampal slices from young rats

NMDA receptor dependent synaptic plasticity was examined in hippocampal slices using a novel pharmacological pairing procedure. Field excitatory postsynaptic potentials (EPSPs) were recorded from the CA1 area of slices maintained in a low Mg(2+) solution using a stimulus rate of 0.1-0.2 Hz. The NMDA receptor antagonist 2-amino-5-phosphonovalerate (AP5) was initially included in the perfusion solution to establish baseline recording of isolated AMPA EPSPs. Washing out AP5 led to the expression of composite EPSPs, containing both AMPA and NMDA receptor mediated components. Following an initial, transient potentiation of the AMPA component, the composite responses gradually decayed for several hours, involving AMPA and NMDA components to a similar extent. This decay was input specific and could be terminated at any stage by reapplication of AP5. Subsequent long-term potentiation (LTP) reversed the effect to an extent inversely related to the degree of depression. Experiments to test the interaction with long-term depression (LTD) revealed a significant but incomplete overlap between the two depression processes. In conclusion, pairing synaptic activation at test stimulus frequency with pharmacological unblocking of NMDA receptors allows for expression of composite EPSPs that decay substantially, due to an active mechanism. The underlying process appears to be at least partly distinct from those involved in homosynaptic LTP and LTD.     

Knowledge of osteoporosis in a Swedish municipality--a prospective study

BACKGROUND: As a part of the Vadstena Osteoporosis Prevention Project, the knowledge of osteoporosis was examined before the intervention program started, after 5 and 10 years. METHODS: At baseline (in 1989) 15% of the population in two Swedish municipalities was randomly invited to the study. The participants in the study group were invited for examination by forearm bone densitometry and a questionnaire concerning lifestyle and risk factors for osteoporosis and also knowledge of osteoporosis, while the subjects in the control group were examined only by questionnaire. Follow-ups were made in 1994 and in 1999. Meanwhile education about osteoporosis was given to the study group, to the public, and to various professionals in the study community. RESULTS: There was a difference in the level of knowledge between the groups prior to the intervention. The rate of increment did not differ significantly between the groups for the study period. Previous participants had 0.58 higher score than new participants in the study group in 1994 (P = 0.031) and 0.76 higher score in 1999 (P < 0.001) regarding the total number of correct answers. The women in the study group had 0.63 higher score than the men in 1994 (P = 0.016) and 1.03 higher score in 1999 (P < 0.001) regarding the total number of correct answers. CONCLUSION: There was no significant effect of a general intervention program concerning the knowledge of osteoporosis in participants in the intervention area compared to the control area.     

Phase I study of peptide receptor radionuclide therapy with [In-DTPA]octreotide: the Rotterdam experience

Fifty patients with somatostatin receptor-positive tumors were treated with multiple doses of [(111)In-diethylenetriamine pentaacetic acid(0)]octreotide. Forty patients were evaluable after cumulative doses of at least 20 GBq up to 160 GBq. Therapeutic effects were seen in 21 patients: partial remission in 1 patient, minor remissions in 6 patients, and stabilization of previously progressive tumors in 14 patients. Our results thus underscore the therapeutic potential of Auger-emitting radiolabelled peptides. The toxicity was generally mild bone marrow toxicity, but 3 of the 6 patients who received more than 100 GBq developed a myelodysplastic syndrome or leukemia. Therefore, we consider 100 GBq as the maximal tolerable dose. With a renal radiation dose of 0.45 mGy/MBq (based on previous studies) a cumulative dose of 100 GBq [(111)In-DTPA(0)]octreotide will lead to 45Gy on the kidneys, twice the accepted limit for external beam radiation. However, no development of hypertension, proteinuria, or significant changes in serum creatinine or creatinine clearance were observed in our patients including 2 patients who received 106 and 113 GBq [(111)In-DTPA(0)]octreotide without protection with amino acids, over a follow-up period of respectively 3 and 2 years. These findings show that the radiation of the short-range (maximal 10 microns) Auger electrons originating from the cells of the proximal tubules is not harmful for the renal function. The decrease in serum inhibin B and concomitant increase of serum FSH levels in men indicate that the spermatogenesis was impaired.     

Concentrations and enantiomer fractions of organochlorine compounds in Baltic species hit by reproductive impairment

Concentrations and enantiomer fractions (EFs) of organochlorine compounds (OCs) were determined in tissues of gray seal (Halichoerus grypus) and salmon (Salmo salar) originating from the Baltic Sea. The selected seal specimens ranged from starved to unstarved animals, and some of them suffered from a disease complex, while the salmon samples originated from individuals, which were known to produce offspring with and without the M74 syndrome. Significant differences in residue levels and EFs were found between seal groups but not between M74 salmon and non-M74 salmon. The relations between chemical and biological variables of seal samples were investigated with multivariate statistics. Poor health status correlated strongly with age, while bad nutrition condition was associated mainly with high pollution loads and distinctively nonracemic chiral OC compositions. High biotransformation rate (as indicated by fraction of chlordane metabolites in relation to total level of chlordanes) was also associated with large deviations from racemic values and high contaminant levels.
