Methods: This study intends to apply a comprehensive field sampling and laboratory protocol (culture-based methods and molecular tools), assess fungal azole resistance, as well as to elucidate potential exposure-related health effects (cytotoxicity analyses). Skin-biota samples (swabs) were performed on workers and controls to identify other exposure routes. Results: In personal filter samples the guidelines in one automated industry surpassed the guidelines for fungi. Seasonal influence on viable microbial contamination including fungi with reduced susceptibility to the tested azoles was observed, besides the observed reduced susceptibility of pathogens of critical priority (Mucorales and Fusarium sp.). Aspergillus sections with potential toxigenic effects and clinical relevance were also detected in all the sampling methods. Discussion: The results regarding skin biota in both controls´ and workers´ hands claim attention for the possible exposure due to hand-to-face/mouth contact. This study allowed the conclusion that working in automated and manual waste sorting plants implies high exposure to microbial agents.info:eu-repo/semantics/publishedVersio

Increasing but levelling out risk of revision due to infection after total hip arthroplasty: a study on 108,854 primary THAs in the Norwegian Arthroplasty Register from 2005 to 2019

Background and purpose — Focus on prevention, surveillance, and treatment of infection after total hip arthroplasty (THA) in the last decade has resulted in new knowledge and guidelines. Previous publications have suggested an increased incidence of surgical revisions due to infection after THA. We assessed whether there have been changes in the risk of revision due to deep infection after primary THAs reported to the Norwegian Arthroplasty Register (NAR) over the period 2005–2019. Patients and methods — Primary THAs reported to the NAR from January 1, 2005 to December 31, 2019 were included. Adjusted Cox regression analyses with the first revision due to deep infection after primary THA were performed. We investigated changes in the risk of revision as a function of time of primary THA. Time was stratified into 5-year periods. We studied the whole population of THAs, and the subgroups: all-cemented, all-uncemented, reverse hybrid (cemented cup), and hybrid THAs (cemented stem). In addition, we investigated factors that were associated with the risk of revision, and changes in the time span from primary THA to revision. Results — Of the 108,854 primary THAs that met the inclusion criteria, 1,365 (1.3%) were revised due to deep infection. The risk of revision due to infection, at any time after primary surgery, increased through the period studied. Compared with THAs implanted in 2005–2009, the relative risk of revision due to infection was 1.4 (95% CI 1.2–1.7) for 2010–2014, and 1.6 (1.1–1.9) for 2015–2019. We found an increased risk for all types of implant fixation. Compared to 2005–2009, for all THAs, the risk of revision due to infection 0–30 days postoperatively was 2.2 (1.8–2.8) for 2010–2014 and 2.3 (1.8–2.9) for 2015–2019, 31–90 days postoperatively 1.0 (0.7–1.6) for 2010–2014 and 1.6 (1.0–2.5) for 2015–2019, and finally 91 days–1 year postoperatively 1.1 (0.7–1.8) for 2010–2014 and 1.6 (1.0–2.6) for 2015–2019. From 1 to 5 years postoperatively, the risk of revision due to infection was similar to 2005–2009 for both the subsequent time periods Interpretation — The risk of revision due to deep infection after THA increased throughout the period 2005–2019, but appears to have levelled out after 2010. The increase was mainly due to an increased risk of early revisions, and may partly have been caused by a change of practice rather than a change in the incidence of infection.publishedVersio

Rare and low-frequency coding variants alter human adult height

Height is a highly heritable, classic polygenic trait with ~700 common associated variants identified so far through genome - wide association studies . Here , we report 83 height - associated coding variants with lower minor allele frequenc ies ( range of 0.1 - 4.8% ) and effects of up to 2 16 cm /allele ( e.g. in IHH , STC2 , AR and CRISPLD2 ) , >10 times the average effect of common variants . In functional follow - up studies, rare height - increasing alleles of STC2 (+1 - 2 cm/allele) compromise d proteolytic inhibition of PAPP - A and increased cleavage of IGFBP - 4 in vitro , resulting in higher bioavailability of insulin - like growth factors . The se 83 height - associated variants overlap genes mutated in monogenic growth disorders and highlight new biological candidates ( e.g. ADAMTS3, IL11RA, NOX4 ) and pathways ( e.g . proteoglycan/ glycosaminoglycan synthesis ) involved in growth . Our results demonstrate that sufficiently large sample sizes can uncover rare and low - frequency variants of moderate to large effect associated with polygenic human phenotypes , and that these variants implicate relevant genes and pathways

Bruk av værradar til å estimere skredutløsende nedbørmengder ved konvektive nedbørhendelser

Denne oppgaven har tatt for seg om værradardata gir et bedre estimat av nedbørmengder da værradardata har en bedre romlig og temporal oppløsning enn interpoleringsmetoden. Det har også blitt sett på et datasett som er produsert ved en kombinasjon av modellert nedbør og in-situ målinger fra værradar og målestasjoner med timesoppløsning.\\ Rapporten kommer frem til at kortidsnedbør i form av bygenedbør kan være skredutløsende og at den høye intensiteten over en kort periode gjerne utløser flomskred. Videre vises de at interpolasjonsmetoden gir for lave nedbørestimat i disse situasjonene. Det vises også at værradaren kan gi en god oppfattelse av bygenedbør, men at den også kan unnlate å fange den opp helt.\\ Det vises også at tersklene som brukes til skredvarsling er basert på en romlig og temporal oppløsning som vil gi feilvarsling i noen tilfeller.\\ Avslutningsvis anbefales det en undersøkelse av modellert nedbør i kombinasjon med in-situ målinger for terskelestimering og skredvarsling. Dette begrunnes med at ingen eksisterende metoder fanger opp nedbørmønstre og nedbørmengder til det fulle, men at en modell vil estimere de samme nedbørmengdene under like forhold og derfor ikke trenger å gi riktig nedbørestimat så lenge terklene og varlslingen benytter samme modell

Purpose Occurrence of airway irritation among indoor swimming pool personnel was investigated. The aims of this study were to assess trichloramine exposure levels and exhaled nitric oxide in relation to the prevalence of airway symptoms in swimming pool facilities and to determine protein effects in the upper respiratory tract. Methods The presence of airway symptoms related to work was examined in 146 individuals working at 46 indoor swimming pool facilities. Levels of trichloramine, as well as exhaled nitric oxide, were measured in five facilities with high prevalence of airway irritation and four facilities with no airway irritation among the personnel. Nasal lavage fluid was collected, and protein profiles were determined by a proteomic approach. Results 17 % of the swimming pool personnel reported airway symptoms related to work. The levels of trichloramine in the swimming pool facilities ranged from 0.04 to 0.36 mg/m3. There was no covariance between trichloramine levels, exhaled nitric oxide and prevalence of airway symptoms. Protein profiling of the nasal lavage fluid showed that the levels alpha-1-antitrypsin and lactoferrin were significantly higher, and S100-A8 was significantly lower in swimming pool personnel. Conclusions This study confirms the occurrence of airway irritation among indoor swimming pool personnel. Our results indicate altered levels of innate immunity proteins in the upper airways that may pose as potential biomarkers. However, swimming pool facilities with high prevalence of airway irritation could not be explained by higher trichloramine exposure levels. Further studies are needed to clarify the environmental factors in indoor swimming pools that cause airway problems and affect the immune system
