Substitution – en løsning på rekrutteringsudfordringer i produktions-Danmark?

Virksomhederne i en række kommuner i provinsen oplever store udfordringer med at skaffe kvalificeret arbejdskraft. Konsekvensen er nu, at de siger nej til ordrer eller udflytter opgaver til andre dele af Danmark – eller til udlandet. Inden da har virksomhederne ofte brugt alle værktøjerne i værktøjskassen for enten at tiltrække eller fastholde medarbejdere. Det er dyrt og tidskrævende. Kan substitution – som foreslået i dette temanummer – være en nøgle til at løse problemerne? Måske. Med afsæt i vores erfaring fra det lokale erhvervsliv i henholdsvis Esbjerg- og Skive-områderne argumenterer vi for, at substitutionsløsningen beror på flere forskellige dimensioner: Et ændret mindset hos virksomhederne løser ikke udfordringen alene. Det er mindst ligeså vigtigt, at de videregående uddannelser øger deres opmærksomhed omkring kandidaternes employability. Og at de højtuddannede vil udvise en højere grad af mobilitet – både fagligt og geografisk. Udflytningerne af statslige styrelser og uddannelsesinstitutioner til provinsen kan være et vigtigt led i den forbindelse

Scaling of maneuvering performance in baleen whales: larger whales outperform expectations

Despite their enormous size, whales make their living as voracious predators. To catch their much smaller, more maneuverable prey, they have developed several unique locomotor strategies that require high energetic input, high mechanical power output and a surprising degree of agility. To better understand how body size affects maneuverability at the largest scale, we used bio-logging data, aerial photogrammetry and a high-throughput approach to quantify the maneuvering performance of seven species of free-swimming baleen whale. We found that as body size increases, absolute maneuvering performance decreases: larger whales use lower accelerations and perform slower pitch-changes, rolls and turns than smaller species. We also found that baleen whales exhibit positive allometry of maneuvering performance: relative to their body size, larger whales use higher accelerations, and perform faster pitch-changes, rolls and certain types of turns than smaller species. However, not all maneuvers were impacted by body size in the same way, and we found that larger whales behaviorally adjust for their decreased agility by using turns that they can perform more effectively. The positive allometry of maneuvering performance suggests that large whales have compensated for their increased body size by evolving more effective control surfaces and by preferentially selecting maneuvers that play to their strengths.We thank the crews of many research vessels including the R/V John Martin, R/V Fluke, ARSV Laurence M.

Prevalence and Incidence Rates of Atrial Fibrillation in Denmark 2004–2018

Purpose: To estimate the prevalence and incidence of atrial fibrillation (AF) in Denmark during 2004– 2018 and to investigate whether methodological choices influence these estimates. Patients and Methods: A register-based cohort study was conducted of all individuals aged ≥ 18 years in Denmark 2004– 2018. The cumulative prevalence of AF at the end of the study period was calculated as the number of AF cases alive with at least one inpatient or two outpatient diagnoses during 1994– 2018 divided by the number of Danish residents in 2018. Incidence rates were calculated as the number of annual AF cases with no previous diagnosis in the past 10 years (ie, a 10-year washout period) divided by the person-time contributed by the population free of AF on 1 January in the same calendar year. Furthermore, the influence of varying case definitions was investigated. Results: The cumulative prevalence of AF was 3.0% in 2018. The incidence rate increased from 391 to 481 per 100,000 person-years (PYs) from 2004 to 2015 (1.7% average annual increase) after which it declined to 367 per 100,000 PYs in 2018 (8.5% average annual decrease). This pattern was observed in both sexes irrespective of age. Methodological choices, particularly the case definition’s strictness and the length of the washout period, had a substantial influence on the reported estimates. Conclusion: The cumulative prevalence of AF is currently around 3.0% in the Danish population, but the incidence has declined since 2015. As these estimates are influenced by methodological choices, future studies should strive for precise reporting of study methodology.publishedVersio

An international observational study to assess the impact of the Omicron variant emergence on the clinical epidemiology of COVID-19 in hospitalised patients

Background: Whilst timely clinical characterisation of infections caused by novel SARS-CoV-2 variants is necessary for evidence-based policy response, individual-level data on infecting variants are typically only available for a minority of patients and settings. Methods: Here, we propose an innovative approach to study changes in COVID-19 hospital presentation and outcomes after the Omicron variant emergence using publicly available population-level data on variant relative frequency to infer SARS-CoV-2 variants likely responsible for clinical cases. We apply this method to data collected by a large international clinical consortium before and after the emergence of the Omicron variant in different countries. Results: Our analysis, that includes more than 100,000 patients from 28 countries, suggests that in many settings patients hospitalised with Omicron variant infection less often presented with commonly reported symptoms compared to patients infected with pre-Omicron variants. Patients with COVID-19 admitted to hospital after Omicron variant emergence had lower mortality compared to patients admitted during the period when Omicron variant was responsible for only a minority of infections (odds ratio in a mixed-effects logistic regression adjusted for likely confounders, 0.67 [95% confidence interval 0.61-0.75]). Qualitatively similar findings were observed in sensitivity analyses with different assumptions on population-level Omicron variant relative frequencies, and in analyses using available individual-level data on infecting variant for a subset of the study population. Conclusions: Although clinical studies with matching viral genomic information should remain a priority, our approach combining publicly available data on variant frequency and a multi-country clinical characterisation dataset with more than 100,000 records allowed analysis of data from a wide range of settings and novel insights on real-world heterogeneity of COVID-19 presentation and clinical outcome
