COVID Obesity: A One-Year Narrative Review
2021
On 11 March 2020, coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO). This study focuses on a narrative review about the illness during the first year of the pandemic in relation to obesity. Databases were used to search studies published up to 8 December 2020. In total, 4430 articles and other scientific literature were found, and 24 articles were included in this one-year narrative review. The mean BMI value of severe COVID-19 patients ranged from 24.5 to 33.4 kg/m2, versus 2 for non-severe patients. Articles using the terms obesity or overweight without indicating the BMI value in these patients were common, but this is not useful, as the a…
Appendicular fracture epidemiology of children and adolescents: a 10-year case review in Western Australia (2005 to 2015)
2018
Fracture incidence data of Australian children and adolescents have not been reported in the literature. A 10-year case review of fracture presentations in Western Australia is provided. Between 2005 and 2015, fracture incidence increased relative to population growth. This is concerning, and interventions are required to reverse this trend. Purpose Fracture incidence in 0–16-year-olds is high and varies between countries. Boys have a 1.5:1 ratio of fracture incidence compared to girls. There are no specific data for Australia. Western Australia is a state with unique geography and population distribution having only a single tertiary paediatric hospital (Princess Margaret Hospital, PMH, in…
Dementia in former amateur and professional contact sports participants : population-based cohort study, systematic review, and meta-analysis
2023
Background Although there is growing evidence that former professional athletes from sports characterised by repetitive head impact subsequently experience an elevated risk of dementia, the occurrence of this disorder in retired amateurs, who represent a larger population, is uncertain. The present meta-analysis integrates new results from individual-participant analyses of a cohort study of former amateur contact sports participants into a systematic review of existing studies of retired professionals and amateurs. Methods The cohort study comprised 2005 male retired amateur athletes who had competed internationally for Finland (1920–1965) and a general population comparison group of 1386 …
Eco-epidemiology of tick- and rodent-borne pathogens in boreal forests
2017
Infectious diseases are amongst the ten major causes of human mortality worldwide, 60% of them being animal-borne. Variations of abiotic and biotic conditions are likely to modify the transmission of parasites and pathogens within reservoir species, and, as a consequence, alter the zoonotic risk for human. My thesis aims at elucidating the dynamics and mechanisms of the maintenance of ticks, tick-borne pathogens (TBPs) and the Puumala hantavirus (PUUV) in the reservoir host, the bank vole (Myodes glareolus, BV). In Northern Europe, tick-borne diseases are growing in importance to human because of the latitudinal expansion of the tick Ixodes ricinus. Field monitoring revealed that I. ricinus…
Gut microbiome and atrial fibrillation - results from a large population-based study
2023
Background Atrial fibrillation (AF) is an important heart rhythm disorder in aging populations. The gut microbiome composition has been previously related to cardiovascular disease risk factors. Whether the gut microbial profile is also associated with the risk of AF remains unknown. Methods We examined the associations of prevalent and incident AF with gut microbiota in the FINRISK 2002 study, a random population sample of 6763 individuals. We replicated our findings in an independent case–control cohort of 138 individuals in Hamburg, Germany. Findings Multivariable-adjusted regression models revealed that prevalent AF (N = 116) was associated with nine microbial genera. Incident AF (N = 5…
Sequential infection can decrease virulence in a fish–bacterium–fluke interaction: Implications for aquaculture disease management
2019
Hosts are typically infected with multiple strains or genotypes of one or several parasite species. These infections can take place simultaneously, but also at different times, i.e. sequentially, when one of the parasites establishes first. Sequential parasite dynamics are common in nature, but also in intensive farming units such as aquaculture. However, knowledge of effects of previous exposures on virulence of current infections in intensive farming is very limited. This is critical as consecutive epidemics and infection history of a host could underlie failures in management practises and medical intervention of diseases. Here, we explored effects of timing of multiple infection on viru…
Alaraajavammojen esiintyvyys salibandyssa ja koripallossa : kuvaileva retrospektiivinen poikittaistutkimus
2015
Mari Riekkinen (2015). Alaraajavammojen esiintyvyys salibandyssa ja koripallossa: kuvaileva retrospektiivinen poikittaistutkimus. Terveystieteiden laitos, Jyväskylän yliopisto, (Liikuntalääketiede), pro gradu -tutkielma, 52 s, 2 liitettä. Salibandyssa (SB) ja koripallossa (K) alaraajavammat ovat yleisiä alaraajoja kuormittavien liikemallien takia. Aikaisemmin on tutkittu jonkin verran nuorten palloilijoiden alaraajavam-mojen esiintyvyyttä, mutta peliuran aikaisista vammoista ei ole tietoa. Tämän tutkimuksen tarkoituksena oli selvittää alle 23-vuotiaiden salibandyn ja koripallon pelaajien peliuran aikana sattuneiden alaraajavammojen epidemiologiaa sekä pelivuosien ja sarjatason vaikutusta va…
Phosphorus limitation enhances parasite impact: feedback effects at the population level
2014
Background Nutrient deficiency affects the growth and population dynamics of consumers. Endoparasites can be seen as consumers that drain carbon (C) or energy from their host while simultaneously competing for limiting resources such as phosphorus (P). Depending on the relative demands of the host and the parasite for the limiting nutrient, intensified resource competition under nutrient limitation can either reduce the parasite’s effect on the host or further reduce the fitness of the nutrient-limited host. So far, knowledge of how nutrient limitation affects parasite performance at the host population level and how this affects the host populations is limited. Results We followed the popu…
