Un grup de cercet\u0103tori din Elve\u021bia a identificat o \u201eamprent\u0103 metabolic\u0103\u201d a priv\u0103rii acute de somn<\/a>, care poate fi detectat\u0103 din saliv\u0103 cu ajutorul inteligen\u021bei artificiale.<\/p>\n

Studiul deschide posibilitatea apari\u021biei unor teste rapide care s\u0103 arate dac\u0103 o persoan\u0103 nu a dormit deloc o noapte \u00eentreag\u0103.<\/p>\n

Studiul, publicat \u00een revista \u0219tiin\u021bific\u0103 Journal of Proteome Research<\/em>, a analizat probe de saliv\u0103 de la 20 de b\u0103rba\u021bi tineri \u0219i s\u0103n\u0103to\u0219i, \u00een trei situa\u021bii diferite: dup\u0103 o noapte complet nedormit\u0103, dup\u0103 patru nop\u021bi cu doar \u0219ase ore de somn, dup\u0103 un program normal de opt ore de somn.<\/p>\n

O singur\u0103 noapte de privare de somn las\u0103 o semn\u0103tur\u0103 distinct\u0103 \u00een saliv\u0103<\/h2>\n

Cercet\u0103torii au folosit metode avansate de analiz\u0103 chimic\u0103 \u0219i algoritmi de machine learning pentru a c\u0103uta modific\u0103ri metabolice produse de lipsa somnului.<\/p>\n

Ei au descoperit c\u0103 o singur\u0103 noapte de privare total\u0103 de somn las\u0103 o \u201esemn\u0103tur\u0103\u201d biologic\u0103 distinct\u0103 \u00een saliv\u0103.<\/p>\n

Potrivit autorilor, sistemul a reu\u0219it s\u0103 identifice corect persoanele private de somn folosind doar 10-12 markeri moleculari.<\/p>\n

Cele mai precise rezultate au fost ob\u021binute diminea\u021ba \u0219i la pr\u00e2nz.<\/p>\n

Reducerea moderat\u0103 a somnului nu a produs modific\u0103ri detectabile<\/h2>\n

\u00cen schimb, reducerea moderat\u0103 a somnului \u2013 patru nop\u021bi consecutive cu \u0219ase ore de somn \u2013 nu a produs modific\u0103ri suficient de clare pentru a putea fi detectate \u00een mod fiabil.<\/p>\n

Autorii spun c\u0103 un astfel de test ar putea avea aplica\u021bii \u00een: siguran\u021ba rutier\u0103, medicina muncii, domeniul clinic, anchetele medico-legale.<\/p>\n

\u00cen prezent, \u00een multe \u021b\u0103ri nu exist\u0103 metode obiective pentru a demonstra dac\u0103 un \u0219ofer era sever privat de somn \u00een momentul unui accident, iar anchetatorii se bazeaz\u0103 \u00een mare parte pe declara\u021bii \u0219i reconstituiri.<\/p>\n

Testul trebuie, \u00eens\u0103, validat pe e\u0219antioane mai mari de popula\u021bie<\/h2>\n

Cercet\u0103torii dau exemplul statului american New Jersey, unde \u201eMaggie\u2019s Law\u201d permite urm\u0103rirea penal\u0103 a \u0219oferilor care au stat trezi mai mult de 24 de ore \u00eenaintea unui accident mortal.<\/p>\n

Totu\u0219i, autorii avertizeaz\u0103 c\u0103 metoda este \u00eenc\u0103 experimental\u0103.<\/p>\n

Studiul a inclus doar b\u0103rba\u021bi tineri \u0219i s\u0103n\u0103to\u0219i, iar testele trebuie validate pe grupuri mai mari \u0219i mai diverse, inclusiv femei, persoane care lucreaz\u0103 \u00een ture sau oameni care folosesc medicamente ori stimulente.<\/p>\n

\u201eAceste modele sunt concepute pentru a identifica starea de privare de somn, nu neap\u0103rat gradul de afectare al unei persoane\u201d, noteaz\u0103 cercet\u0103torii.<\/p>\n","protected":false},"excerpt":{"rendered":"
