Finnish nationwide allergy programme 2008–2018 changed attitudes and reduced morbidity

Vertaisarvioitu. English summary.Lähtökohdat : Allergiaohjelma 2008–2018 on kansallinen kansanterveysohjelma, jonka avulla välttö¬strategia on käännetty sietostrategiaksi ja painotettu allergiaterveyttä. Raportoimme 10 vuoden tulokset. Menetelmät : Ohjelmalla oli kuusi tavoitetta, joiden toteuttamiseksi määriteltiin tehtävät, työkalut ja mittarit. Ohjelmaa toteutettiin kouluttamalla terveydenhuoltoa ja viestimällä väestölle. Tulokset : Astman ja allergisen nuhan esiintyvyys tasoittui asevelvollisissa ja Helsingin aikuisväestössä. Helsingin aikuisista astmaatikoista 41 % oli ollut vuoden 2016 kyselyä edeltäneen vuoden oireettomia (31 % 2006). Lasten allergiaruokavaliot vähenivät koko maassa noin puoleen. Työperäiset allergiset sairaudet vähenivät 45 %. Astman sairaalahoidon tarve puolittui, mutta päivystyskäynnit vähenivät oleellisesti vain lapsilla. Anafylaksia aiheutti aiempaa enemmän päivystyskäyntejä. Allergiasta ja astmasta aiheutuvat vuosittaiset suorat ja epäsuorat kustannukset vähenivät 200 miljoonaa euroa ¬(30 %) verrattaessa vuosia 2007 ja 2018. Päätelmät : Allergian ja astman aiheuttama sairastavuus ja niistä koituvat kustannukset vähenivät merkittävästi. Haitat vähenivät aluksi nopeasti, myöhemmin hitaammin. Ammattilaiset ja suuri yleisö hyväksyivät uuden suunnan, jossa painottuivat sietokyky ja terveys allergiasta huolimatta. Tietoon perustuvat systemaattiset ohjelmat ovat vahva keino parantaa kansanterveyttä.Peer reviewe

Analysis of shared common genetic risk between amyotrophic lateral sclerosis and epilepsy

Because hyper-excitability has been shown to be a shared pathophysiological mechanism, we used the latest and largest genome-wide studies in amyotrophic lateral sclerosis (n = 36,052) and epilepsy (n = 38,349) to determine genetic overlap between these conditions. First, we showed no significant genetic correlation, also when binned on minor allele frequency. Second, we confirmed the absence of polygenic overlap using genomic risk score analysis. Finally, we did not identify pleiotropic variants in meta-analyses of the 2 diseases. Our findings indicate that amyotrophic lateral sclerosis and epilepsy do not share common genetic risk, showing that hyper-excitability in both disorders has distinct origins

Genetic correlation between amyotrophic lateral sclerosis and schizophrenia

A. Palotie on työryhmän Schizophrenia Working Grp Psychiat jäsen.We have previously shown higher-than-expected rates of schizophrenia in relatives of patients with amyotrophic lateral sclerosis (ALS), suggesting an aetiological relationship between the diseases. Here, we investigate the genetic relationship between ALS and schizophrenia using genome-wide association study data from over 100,000 unique individuals. Using linkage disequilibrium score regression, we estimate the genetic correlation between ALS and schizophrenia to be 14.3% (7.05-21.6; P = 1 x 10(-4)) with schizophrenia polygenic risk scores explaining up to 0.12% of the variance in ALS (P = 8.4 x 10(-7)). A modest increase in comorbidity of ALS and schizophrenia is expected given these findings (odds ratio 1.08-1.26) but this would require very large studies to observe epidemiologically. We identify five potential novel ALS-associated loci using conditional false discovery rate analysis. It is likely that shared neurobiological mechanisms between these two disorders will engender novel hypotheses in future preclinical and clinical studies.Peer reviewe

On the evaluation of ALD TiO2, ZrO2 and HfO2 coatings on corrosion and cytotoxicity performances

Magnesium alloys have been widely studied as materials for temporary implants, but their use has been limited by their corrosion rate. Recently, coatings have been proven to provide an effective barrier. Though only little explored in the field, Atomic Layer Deposition (ALD) stands out as a coating technology due to the outstanding film conformality and density achievable. Here, we provide first insights into the corrosion behavior and the induced biological response of 100 nm thick ALD TiO2, HfO2 and ZrO2 coatings on AZ31 alloy by means of potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS), hydrogen evolution and MTS colorimetric assay with L929 cells. All three coatings improve the corrosion behavior and cytotoxicity of the alloy. Particularly, HfO2 coatings were characterized by the highest corrosion resistance and cell viability, slightly higher than those of ZrO2 coatings. TiO2 was characterized by the lowest corrosion improvements and, though generally considered a biocompatible coating, was found to not meet the demands for cellular applications (it was characterized by grade 3 cytotoxicity after 5 days of culture). These results reveal a strong link between biocompatibility and corrosion resistance and entail the need of taking the latter into consideration in the choice of a biocompatible coating to protect degradable Mg-based alloys

Artificial neural networks can be effectively used to model changes of intracranial pressure (ICP) during spinal surgery using different non invasive ICP surrogate estimators

Artificial Intelligence (AI) techniques play a major role in anesthesiology, even though their importance is often overlooked. In the extant literature, AI approaches, such as Artificial Neural Networks (ANNs), have been underutilized, mainly being used to model patient's consciousness state, to predict the precise amount of anesthetic gases, the level of analgesia, or the need of anesthesiological blocks, among others. In the field of neurosurgery, ANNs have been effectively applied to the diagnosis and prognosis of cerebral tumors, seizures, low back pain, and also to the monitoring of intracranial pressure (ICP)
