Elämänlaadun ja toimintakyvyn muutokset ikääntyneillä aivoverenkiertohäiriön sairastaneilla kävelyn ja käden tehostetun käytön kuntoutuksen aikana

65–85-vuotiaiden aivoverenkiertohäiriön (AVH:n) sairastaneiden (n = 270) kuntoutustutkimus toteutettiin osana Kelan kehittämishanketta. Kontrolloimattomassa seurantatutkimuksessa selvitettiin laitos- ja avomuotoisen kävely- ja käsikuntoutuksen aikana tapahtuneita muutoksia elämänlaadussa ja toimintakyvyssä. Kävelykuntoutus sisälsi painokevennettyä ja muuta kävelyharjoittelua. Käsikuntoutus sisälsi halvaantuneen käden tehostetun käytön harjoittelua. Kävelykuntoutuksen perusjakson kesto laitos- ja avokuntoutuksessa oli 20/18 vrk, käsikuntoutuksen 14/13 vrk. Seurantajaksot I (6 vrk) ja II (2 vrk, loppumittaukset) toteutettiin 6 ja 12 kuukauden kuluttua perusjakson päättymisestä. Alkutilanteessa kävelyn avokuntoutujissa itsenäisesti käveleviä (FAC) oli enemmän kuin laitoskuntoutujissa. Laitoskuntoutujilla itsenäisesti kävelevien määrä kasvoi 45 %:sta 63 %:iin. Molemmilla ryhmillä kävelymatka (6 min) piteni. Laitoskuntoutujilla motorinen ja kognitiivinen toiminta (FIM) paranivat. Avokuntoutujien motoriset ja prosessitaidot (AMPS) paranivat. Laitoskuntoutujien elämänlaatupisteet ympäristön osa-alueella (WHOQOL-BREF) nousivat. Alkutilanteessa yläraajan toimintakyky (WMFT) oli käden laitoskuntoutujilla parempi kuin avokuntoutujilla. Molemmissa ryhmissä halvaantuneen yläraajan toimintakyky koheni. Laitoskuntoutujien puristusvoima (dynamometri) ja avokuntoutujilla motoriset taidot (AMPS) paranivat. Tutkittavien iän, sukupuolen, sairastamisajan ja toimintakyvyn lähtötason yhteyttä tutkittiin toimintakykyä kuvaavien mittareiden muutoksiin. Vain alhainen lähtötaso ennakoi parempaa edistymistä mittaustuloksissa. Ikääntynyttä AVH:n sairastanutta kannattaa kuntouttaa kävelyn, halvaantuneen yläraajan käytön sekä päivittäisistä toiminnoista suoriutumisen parantamiseksi

Does the company's economic performance affect access to occupational health services?

<p>Abstract</p> <p>Background</p> <p>In Finland like in many other countries, employers are legally obliged to organize occupational health services (OHS) for their employees. Because employers bear the costs of OHS it could be that in spite of the legal requirement OHS expenditure is more determined by economic performance of the company than by law. Therefore, we explored whether economic performance was associated with the companies' expenditure on occupational health services.</p> <p>Methods</p> <p>We used a prospective design to predict expenditure on OHS in 2001 by a company's economic performance in 1999. Data were provided by Statistics Finland and expressed by key indicators for profitability, solidity and liquidity and by the Social Insurance Institution as employers' reimbursement applications for OHS costs. The data could be linked at the company level. Regression analysis was used to study associations adjusted for various confounders.</p> <p>Results</p> <p>Nineteen percent of the companies (N = 6 155) did not apply for reimbursement of OHS costs in 2001. The profitability of the company represented by operating margin in 1999 and adjusted for type of industry was not significantly related to the company's probability to apply for reimbursement of the costs in 2001 (OR = 1.00, 95%CI: 0.99 to 1.01). Profitability measured as operating profit in 1999 and adjusted for type of industry was not significantly related to costs for curative medical services (Beta -0.001, 95%CI: -0.00 to 0.11) nor to OHS cost of prevention in 2001 (Beta -0.001, 95%CI: -0.00 to 0.00).</p> <p>Conclusion</p> <p>We did not find a relation between the company's economic performance and expenditure on OHS in Finland. We suppose that this is due to legislation obliging employers to provide OHS and the reimbursement system both being strong incentives for employers.</p

MiR-34b is associated with clinical outcome in triple-negative breast cancer patients

<p>Abstract</p> <p>Background</p> <p>Breast cancer is the most common malignancy with the highest incidence rates among women worldwide. Triple-negative breast cancer (TNBC) represents the major phenotype of basal-like molecular subtype of breast cancer, characterized by higher incidence in young women and a very poor prognosis. MicroRNAs (miRNAs) are small non-coding RNAs playing significant role in the pathogenesis of many cancers including breast cancer. Therefore, miRNAs are also potential prognostic and/or predictive biomarkers in triple-negative breast cancer patients.</p> <p>Methods</p> <p>Thirty-nine TNBC patients with available formalin-fixed paraffin-embedded (FFPE) tissues were enrolled in the study. MiR-34a, miR-34b, and miR-34c were analyzed using qRT-PCR and correlated to clinico-pathological features of TNBC patients.</p> <p>Results</p> <p>Expression levels of miR-34b significantly correlate with disease free survival (DFS) (<it>p </it>= 0.0020, log-rank test) and overall survival (OS) (<it>p </it>= 0.0008, log-rank test) of TNBC patients. No other significant associations between miR-34a, miR-34b, and miR-34c with available clinical pathological data were observed.</p> <p>Conclusions</p> <p>MiR-34b expression negatively correlates with disease free survival and overall survival in TNBC patients. Thus, miR-34b may present a new promising prognostic biomarker in TNBC patients, but independent validations are necessary.</p

Dissecting the Mechanisms Underlying Short-Interval Intracortical Inhibition Using Exercise

Recently, 2 physiologically distinct phases of short-interval intracortical inhibition (SICI) have been identified, a larger phase at interstimulus interval (ISI) 3 ms and a smaller phase at ISI 1 ms. While the former is mediated by synaptic processes, the mechanisms underlying the first phase of SICI remain a matter of debate. Separately, it is known that fatiguing hand exercise reduces SICI, a measure of cortical excitability. Consequently, the present study assessed effects of fatiguing hand exercise on the 2 SICI phases, using threshold tracking transcranial magnetic stimulation techniques, to yield further information on underlying mechanisms. Studies were undertaken on 22 subjects, with SICI assessed at baseline, after each voluntary contraction (VC) period of 120 s and 5, 10, and 20 min after last VC, with responses recorded over abductor pollicis brevis. Exercise resulted in significant reduction of SICI at ISI 1 ms (SICIbaseline 9.5 ± 2.7%; SICIMAXIMUM REDUCTION 2.5 ± 2.5%, P < 0.05) and 3 ms (SICIbaseline 16.8 ± 1.7%; SICIMAXIMUM REDUCTION 11.6 ± 2.1%, P < 0.05), with the time course of reduction being different for the 2 phases. Taken together, findings from the present study suggest that synaptic processes were the predominant mechanism underlying the different phases of SICI

To stimulate or not to stimulate? A rapid systematic review of repetitive sensory stimulation for the upper-limb following stroke

Abstract: Background: Repetitive sensory stimulation (RSS) is a therapeutic approach which involves repeated electrical stimulation of the skin’s surface to improve function. This rapid systematic review aimed to describe the current evidence for repetitive sensory stimulation (RSS) in rehabilitation of the upper-limb for people who have had a stroke. Main text: Methods: Relevant studies were identified in a systematic search of electronic databases and hand-searching in February 2020. The findings of included studies were synthesized to describe: the safety of RSS, in whom and when after stroke it has been used, the doses used and its effectiveness. Results: Eight studies were included. No serious adverse events were reported. The majority of studies used RSS in participants with mild or moderate impairments and in the chronic stage after stroke. Four studies used RSS in a single treatment session, reporting significant improvements in strength and hand function. Findings from longitudinal studies showed few significant differences between control and experimental groups. Meta-analysis was not possible due to the heterogeneity of included studies. Conclusions: This review suggests that there is insufficient evidence to support the use of RSS for the upper-limb after stroke in clinical practice. However, this review highlights several clear research priorities including establishing the mechanism and in whom RSS may work, its safety and optimal treatment parameters to improve function of the upper-limb after stroke

A narrative review on haptic devices: relating the physiology and psychophysical properties of the hand to devices for rehabilitation in central nervous system disorders

Purpose. This paper provides rehabilitation professionals and engineers with a theoretical and pragmatic rationale for the inclusion of haptic feedback in the rehabilitation of central nervous system disorders affecting the hand.Method. A narrative review of haptic devices used in sensorimotor hand rehabilitation was undertaken. Presented papers were selected to outline and clarify the underlying somatosensory mechanisms underpinning these technologies and provide exemplars of the evidence to date.Results. Haptic devices provide kinaesthetic and/or tactile stimulation. Kinaesthetic haptics are beginning to be incorporated in central nervous system rehabilitation, however, there has been limited development of tactile haptics. Clinical research in haptic rehabilitation of the hand is embryonic but initial findings indicate potential clinical benefit. Conclusions. Haptic rehabilitation offers the potential to advance sensorimotor hand rehabilitation but both scientific and pragmatic developments are needed to ensure that its potential is realised.<br/
