<p>The Centers for Disease Control and Prevention has recently reported an increasing number of clinically reported cases of lung injury following use of e-cigarette/vaping products. The cause(s) of this growing epidemic of vaping associated pulmonary injury remain unidentified, though vitamin E acetate has been recently identified as one possible causative agent (see <i>Nature</i> 574, 303 (2019). A combined analytical, theoretical and experimental study has shown that the vaping of vitamin E acetate has the potential to produce exceptionally toxic ketene gas, which may be a contributing factor to the upsurge in lung injuries associated with using some vaping products.</p>

Absztrakt: Több mint ezer olyan légúti megbetegedést tart számon a Centers for Disease Control and Prevention (Atlanta, GA, USA), amelynek köze lehet az elektromos cigaretta használatához. Több mint nyolcszáz esetről bizonyosodott be (közülük 18 halálos kimenetelű volt), hogy vaporizálással összefüggő tüdősérülésről (vaping-associated lung injury – VALI) van szó. Bizonyosnak látszik az is, hogy az e-cigarettákban (mind a nikotin-, mind a kannabiszpatronokban) használt folyadékok több alkotóeleme potenciálisan mérgező. Még nem pontosan tisztázott ugyan, hogy mely komponens(ek) felelősek(ek) az esethalmozódásért, de a vizsgálatok fókuszában főleg olyan folyadékpatronok állnak, amelyek kannabiszszármazékokat tartalmaznak, a betegek nagy része ugyanis legális vagy illegális kannabiszolajat használt. A közegészségügyi hatóságok az e-pöfékelést világszerte mindeddig a dohányzás biztonságos alternatívájaként jegyezték. Azokban az országokban, ahol a kannabisz használata legális, az e-cigaretták hallatlan népszerűségre tettek szert diszkrét használatuk okán, humán vizsgálatok azonban még nem történtek a kannabisz-hatóanyagok e-cigarettával történő porlasztásával kapcsolatban, ezért ennek a beviteli útnak a biztonságossága nem ismert. Egy 2017-ben megjelent áttekintő cikk azzal a következtetéssel zárta értekezését, hogy az e-cigaretták biztonságossága ismeretlen ugyan, ám feltételezhető, hogy kevésbé káros, mint a kannabisztartalmú cigaretták szívása. Magyar, amerikai, ausztrál és európai szakmai szervezetek 2015 óta figyelmeztettek a szabályozatlan terjesztésben rejlő veszélyekre, ugyanakkor elkötelezték magukat a jövőbeli alapos klinikai vizsgálatok szükségessége mellett. Amennyiben a jelenlegi vizsgálatok kimutatják, hogy az e-cigarettázás maga nem feltétlenül káros, akkor alkalmasint új út nyílhat a kannabisz orvosi célú kutatásában és alkalmazásában, ellenkező esetben azonban jelentős változások várhatók a dohánytermékek piacán és a leszoktatást segítő programokban.

Purpose The Centers for Disease Control and Prevention (CDC) recently released guidelines for rehabilitation professionals regarding the care of children with mild traumatic brain injury (mTBI). Given that mTBI impacts millions of children each year and can be particularly detrimental to children in middle and high school age groups, access to universal recommendations for management of postinjury symptoms is ideal. Method This viewpoint article examines the CDC guidelines and applies these recommendations directly to speech-language pathology practices. In particular, education, assessment, treatment, team management, and ongoing monitoring are discussed. In addition, suggested timelines regarding implementation of services by speech-language pathologists (SLPs) are provided. Specific focus is placed on adolescents (i.e., middle and high school–age children). Results SLPs are critical members of the rehabilitation team working with children with mTBI and should be involved in education, symptom monitoring, and assessment early in the recovery process. SLPs can also provide unique insight into the cognitive and linguistic challenges of these students and can serve to bridge the gap among rehabilitation and school-based professionals, the adolescent with brain injury, and their parents. Conclusion The guidelines provided by the CDC, along with evidence from the field of speech pathology, can guide SLPs to advocate for involvement in the care of adolescents with mTBI. More research is needed to enhance the evidence base for direct assessment and treatment with this population; however, SLPs can use their extensive knowledge and experience working with individuals with traumatic brain injury as a starting point for post-mTBI care.
