Kammiovärinäpotilaiden selviytyminen HUS-alueella

Sydänpysähdykset ovat huomattava kuolinsyy sairaalaan ulkopuolella. Sydänpysähdyksen saaneista potilaista parhaat selviytymismahdollisuudet ovat niillä, joiden sydän on elottomuuden jälkeen iskettävässä rytmissä, useimmiten kammiovärinässä. Tutkimuksen tarkoituksena oli selvittää sairaalan ulkopuolella sydänpysähdyksen saaneiden potilaiden selviytymistä Helsingin ja Uudenmaan sairaanhoitopiirin (HUS) eri sairaanhoitoalueilla, ja tarkastella paikallisten hoitoprotokollien vaikutuksia selviytymiseen. Helsingin osalta selvitys on tehty jo aiemmin, joten se rajattiin aineiston ulkopuolelle. Tutkimuksessa kerättiin vuoden 2015 ensihoitokertomuksista elottomat potilaat, joiden lähtörytmi oli iskettävä. Suurin osa potilaista löytyi merkityn lähtörytmin perusteella, mutta osa löytyi kuljetuskoodin perusteella. Tutkimuksissa sydänpysähdyspotilaat on tapana raportoida Utsteinin mallin mukaan. Ensihoito- ja potilaskertomuksista kerättiin tietoa potilaista mallin mukaisesti demografiasta, ensihoitotoimenpiteistä, sairaalahoidosta ja selviytymisestä. Potilaita oli 87. Maallikkoelvytystä heistä sai 78,3 %. Ensihoidon tavoittamisviiveen mediaani oli 7:59 min hätäpuhelun alusta. Enemmistöllä (53,6 %) potilaista lopullisena ilmatienhallintavälineenä oli intubaatio. Sairaalassa viilennyshoitoa sai 65,1 % sinne selviytyneistä. Kaikkiaan 25 potilasta (28,7 %) kotiutui sairaalasta hyvällä neurologisella toimintakyvyllä. Tutkimuksesta saadut luvut olivat linjassa aiemman tutkimuskirjallisuuden kanssa, kun tarkasteltiin koko sairaanhoitopiirin aluetta. Potilasmäärän vähyyden vuoksi sairaanhoitoalueiden välillä ei voitu tehdä havaintoja. Lisätutkimusta tarvittaisiin elvytyslääkkeiden käytöstä, jotta lääkkeidenannon viiveen vaikutus potilaan ennusteeseen selviäisi

Accessing nanomechanical resonators via a fast microwave circuit

The measurement of micron-sized mechanical resonators by electrical techniques is difficult, because of the combination of a high frequency and a small mechanical displacement which together suppress the electromechanical coupling. The only electromagnetic technique proven up to the range of several hundred MHz requires the usage of heavy magnetic fields and cryogenic conditions. Here we show how, without the need of either of them, to fully electrically detect the vibrations of conductive nanomechanical resonators up to the microwave regime. We use the electrically actuated vibrations to modulate an LC tank circuit which blocks the stray capacitance, and detect the created sideband voltage by a microwave analyzer. We show the novel technique up to mechanical frequencies of 200 MHz. Finally, we estimate how one could approach the quantum limit of mechanical systems

Caries Experience and Erosive Tooth Wear in Finnish Men Conscripts 2021 : A Cross-Sectional Study

Background: In Finland, the development of oral health in young, 19- to 21-year-old males regarding restorative treatment need seems to have slowed down according to cross-sectional conscript studies between 1976 and 2011. At the individual level, the mean number of decayed teeth (DT > 0) has also steadily continued to decline. In Finland, military service is mandatory, and around 85% of males complete it. The aim of this cross-sectional study was to investigate the oral health status of young men at the beginning of the 2020s. Methods: The data were collected in July 2021 in the eight biggest Finnish Defence force garrisons by ten calibrated dentists serving in the ranks. The inclusion criteria for this study were a year of birth between 2000 and 2002 and male gender (n = 508). Third molars were included. Restorative treatment need was evaluated using ICDAS scoring. The study was designed according to the STROBE guidelines. Results: Mean DT value was 1.13 when third molars were included and 1.03 when they were excluded. Mean DMFT value was 3.23 and 2.98, respectively. The proportion of conscripts with DT > 0 was 36.4% and 34.8%, respectively. The prevalence of caries was concentrated among a small number of conscripts. Most (76.5%) had BEWE (basic erosive wear examination) of 0-2. Conscripts in the moderate and severe ETW (erosive tooth wear) groups (BEWE 3-13) comprised 23.5% of the cohort. None of the conscripts fell into the most severe group (BEWE 14-18). Conclusions: The oral health of conscripts has improved over the last ten years, and restorative treatment need has decreased significantly. Compared to previous studies, restorative treatment need was concentrated on an even smaller proportion of conscripts.Peer reviewe

Koronarokotukset syystalvella 2023 : suositus ja näyttöpohja

THL antoi toukokuussa 2023 ennakkoarvion koronarokotusten tehosteannoskierroksesta syystalvelle 2023 toteutettavaksi influenssarokotusten yhteydessä. Toukokuussa ei vielä ollut tiedossa syksyllä käytettävissä olevien uusien rokotevalmisteiden koostumus eikä Suomeen saatavien rokotteiden määrä. Sen vuoksi THL antoi ennakkoarvion, jota luvattiin tarkentaa elokuussa. Vuosi sitten THL antoi syystalven tehosteannossuosituksen kaikille 65 vuotta täyttäneille, 18 vuotta täyttäneille riskiryhmiin kuuluville sekä 12 vuotta täyttäneille voimakkaasti immuunipuutteisille. Olennaista oli, että rokotettava sai yhden varianttiräätälöidyn tehosteannoksen, kun oli kulunut vähintään 3 kuukautta edellisestä rokoteannoksesta tai sairastetusta koronataudista. Tällä yhdellä tehosteannoksella saatiin riskiryhmiin kuuluville lisäsuojaa vakavaa tautia vastaan talvikaudelle, jolloin hengitystieinfektioiden ilmaantuvuus yleensä kasvaa. Tehosteannos suositeltiin annettavaksi influenssarokotusten yhteydessä. Syystalvelle 2023 annetaan samanlainen suositus, mutta rokotteena käytetään XBB.1.5-räätälöityä rokotetta. THL on seurannut jatkuvasti koronan epidemiatilannetta, rokotusten suojatehoa ja turvallisuutta, sairaalahoidon ilmaantuvuutta sekä kertynyttä tutkimustietoa. THL julkaisi maaliskuussa 2023 kattavan työpaperin koronarokotuksista numeroinnilla 11/2023. Nykyhetkeen verrattuna muuttumattomina pysyneet asiat on jätetty pois tästä työpaperista. Tämä työpaperi esittelee tilannetta touko-elokuussa 2023. Työpaperi sisältää toukokuun ennakkoarvion sekä kesän aikana tehdyt tarkennukset syystalven 2023 koronarokotuksista
