Haastavatko simulaattorit perinteisen fantom-harjoittelun?

Fantom-harjoittelu on ollut pitkään perinteinen harjoittelumenetelmä, jonka avulla hammaslääketieteen opiskelijat ovat harjoitelleet tarvittavia kliinisiä taitoja ennen potilastyöharjoitteluun siirtymistä. Fantom-harjoittelun rinnalle on kehitetty erilaisia tietotekniikkaa hyödyntäviä potilassimulaattoreita, joiden tarkoituksena on tarjota uudenlaisia oppimistapoja. Tässä työssä käsitellään simulaatio-ohjelmistojen käyttöä hammaslääkärikoulutuksessa sekä hammaslääketieteen 3.vuosikurssille kariologian ja parodontologian fantom-harjoitteluiden jälkeen tehtyä kyselyä ja sen tuloksia. Kyselyssä kartoitettiin, minkälaiset asiat opiskelijat kokivat ongelmallisiksi fantom-harjoittelussa ja niiden perusteella pohditaan, voisiko simulaatio-harjoittelu auttaa opiskelijoita oppimaan paremmin. Pääosa kyselyyn vastanneista opiskelijoista koki olevansa valmis hoitamaan potilasta kariologian ja parodontologian fantom-harjoitteluiden jälkeen. Kyselyssä tuli ilmi, että moni opiskelija koki fantom-harjoittelussa oppimista haittaavana tekijänä opettajaresurssien vähäisyyden. Simulaatioharjoittelulla voitaisiin mahdollisesti suunnata opettajaresursseja tehokkaammin ja siten parantaa opiskelijoiden oppimista

Beat-to-beat variability of T-wave in multichannel magnetocardiogram and

this paper we describe the magnetocardiographic response to several autonomic function tests in healthy young male subjects. Changes found during the handgrip test and cold pressure test were minor. The effect of mental stress was also small, but in two healthy subjects significant T-wave alterations were described. Thus, non-specific T-wave changes may occur in subjects without known heart disease during sympathetic stimulation induced in this manne

The association between bone turnover markers and kyphosis in community-dwelling older adults

Purpose: Hyperkyphosis, accentuated curvature of the thoracic spine, is often attributed to osteoporosis, yet its underlying pathophysiology is not well understood. Bone turnover markers (BTM) reflect the dynamic process of bone formation and resorption. This study examined the association between serum BTM levels and kyphosis in community-dwelling older adults. Methods: Between 2003 and 2006, 760 men and women in the Rancho Bernardo Study age 60 and older had blood drawn and kyphosis measured. Fasting serum was assayed for N-telopeptide (NTX) and procollagen type 1 n-terminal propeptide (P1NP), markers of bone resorption and formation, respectively. Participants requiring two or more 1.7 cm blocks under their head to achieve a neutral supine position were classified as having accentuated kyphosis. Analyses were stratified by sex and use of estrogen therapy (ET). Odds of accentuated kyphosis were calculated for each standard deviation increase in log-transformed BTM. Results: Mean age was 75 years. Overall, 51% of 341 non-ET using women, 41% of 111 ET-using women, and 75% of 308 men had accentuated kyphosis. In adjusted models, higher P1NP and NTX were associated with decreased odds of accentuated kyphosis in non-ET using women (P1NP: OR = 0.78 [95% CI, 0.58–0.92]; NTX: OR = 0.68 [95% CI, 0.54–0.86]), but not in men or ET-using women (p > 0.05). Conclusions: The selective association of higher bone turnover with reduced odds of accentuated kyphosis in non-ET using women suggests that elevated BTM were associated with a lower likelihood of hyperkyphosis only in the low estrogen/high BTM environment characteristic of postmenopausal women who are not using ET.
