Hyperosmolar therapy for acute brain injury: study protocol for an umbrella review of meta-analyses and an evidence mapping
2020
Introduction Acute brain injury is a challenging public health problem worldwide. Elevated intracranial pressure is a common complication after acute brain injury. Hyperosmolar therapy is one of the main therapeutic strategies for the management of intracranial hypertension. This study protocol outlines an umbrella review of meta-analyses which will investigate the benefits and harms of hyperosmolar therapy routinely used for the management of acute brain injury in the intensive care. Methods and analysis We will search PubMed/MEDLINE, EMBASE and the Cochrane Database of Systematic Reviews. We will include meta-analyses of primary research studies (eg, randomised controlled trials, observat…
Physical activity reduces the risk of pneumonia : systematic review and meta-analysis of 10 prospective studies involving 1,044,492 participants
2022
The beneficial effects of regular physical activity in promoting health and preventing chronic diseases are well documented. The relationship between regular physical activity and the risk of pneumonia is uncertain. We aimed to evaluate the magnitude and specificity of the prospective association between regular physical activity and the risk of pneumonia using a systematic review and meta-analysis of published observational cohort studies in general populations. Relevant studies with at least 1 year of follow-up were sought from inception until 15 September 2021 in MEDLINE, Embase, Web of Science, and manual search of relevant articles. Relative risks (RRs) with 95% confidence intervals (C…
Infective Endocarditis: Preliminary Results of a Cohort Study in the Southern Italian Population.
2020
Background Infective endocarditis (IE) is an uncommon disease with an involved interplay of clinical and surgical team management. We aimed to define diagnosis parameters and delineate in-hospital management in patients with IE admitted in a tertiary hospital of Southern Italian. Materials and methods Fifty-six consecutive patients (42 males, 14 females; age range: 34-85 years) admitted for IE in the Infectious Diseases, Cardiac Surgery, and Cardiology units, between January 2011 and August 2017, were enrolled. Demographic data, mortality, comorbidities, specimen type, microscopy results, special histological staining performed, and antimicrobial therapy were collected and analyzed. Any com…
Survie et/ou réactivation de microorganismes du sol sous hautes pressions gazeuses
2012
National audience; Le sol constitue une réserve considérable de microorganismes représentatifs de nombreuses communautés cellulaires. Les recherches reposent sur l’hypothèse qu’il existe, dans les échantillons de sol, des communautés microbiennes adaptées à des conditions physiques (pression, température) très différentes de celles rencontrées dans nos laboratoires : soit parce que les conditions de milieu ont changé (sol), soit parce que les conditions de prélèvement sont très différentes des conditions de culture (grands fonds marins). Dans cette optique, l’utilisation des hautes pressions gazeuses (200-1000 bars dans un premier temps) est envisagée afin d’essayer de réactiver des microor…
International students' language use and attitudes towards English and Finnish
2014
Vaihto-opiskelu on kasvattanut suosiotaan sekä maailmanlaajuisesti että Suomessa erityisesti korkea-asteen opiskelijoiden keskuudessa. Suomi kohdemaana on hyvä esimerkki siitä, ettei nykyään pääsyy ulkomailla opiskeluun ole välttämättä kohdemaan kielen oppiminen, sillä maahan tullaan yleensä ilman paikallisten kielten osaamista ja opinnot suoritetaan englanniksi. Tämän tutkielman tarkoituksena oli kuvata, miten kansainväliset vaihto- ja tutkinto-opiskelijat käyttävät englantia, suomea ja muita osaamiaan kieliä Suomessa oleskelunsa aikana. Tarkemmin ottaen pyrittiin selvittämään, missä konteksteissa, mitä varten, keiden kanssa, kuinka usein ja kuinka onnistuneesti kansainväliset opiskelijat …
Stages of Exercise Behavior Change in a Digital Wellness Program for Aged People : Relationship With Self-Efficacy for Exercise
2022
Sustained physical activity and exercise are central to healthy ageing. Yet, the majority of aged people are insufficiently physically active. Digital wellness technologies are potential in promoting exercise behaviors among aged people, but more detailed research on their potential to promote behavior change is limited. To address this gap, the purpose is to investigate how partaking in a digital wellness program influences the stage of exercise behavior change among aged people and to test whether self-efficacy for exercise can differentiate the program participants in terms of the stages of change. The investigation builds on the stages of exercise behavior change derived from the transt…
Molecular study on nosocomial Pseudomonas aeruginosa strains.
1989
Nosocomial Pseudomonas aeruginosa isolates were typed by DNA fingerprinting techniques. Chromosomal DNA banding patterns, after endonuclease digestion, of six isolates from a neonatal care unit confirmed the results of O-serotyping and antimicrobial susceptibility pattern analysis. In contrast, the characterization by chromosomal DNA fingerprinting of P. aeruginosa strains isolated from patients treated in a burn unit disagreed with the two classic typing methods: in fact, isolates that varied in serotype and antibiograms showed identical restriction endonuclease profiles, whereas two indistinguishable isolates cultured from individual patients were easily and reproducibly differentiated by…
Environmental features of deep-sea habitats linked to the genetic population structure of a crustacean species in the Mediterranean Sea
2009
The deep-sea habitat, from 200 to 2000 m depth, has long been thought as an ecosystem where biotic and abiotic factors vary very little and consequently species are not disturbed by processes and phenomena which could promote fast evolutionary mechanisms. Unfortunately, biological information relating to deep water is limited, especially regarding the population genetics of species inhabiting the Mediterranean Sea, and general patterns cannot be inferred. In this study we report data on the population genetic structure of Aristeus antennatus, a deep-sea decapod crustacean species which has been widely studied due to its important economic value. We surveyed and examined the variation in a 3…
‘So close, yet so different’ – reflections on the multicultural course of Slavic languages
2019
The complexity of language learning may be expanded to learning the languages belonging to the same language family, for example, Slavic languages. This paper reports on the reflection-on action research aimed at the increase of learners’ multicultural competence and enhancement of critical thinking at the interdisciplinary, blended course of Slavic languages and cultures. The course organized in modules is implemented in Moodle. Course content is designed by the teacher; however, Slavic languages are presented by native speakers of these languages. Learners have an opportunity to get familiar with Slavic languages, history, and culture from the presenters’ perspective, what generally resul…
Genetic burden in multiple sclerosis families
2013
A previous study using cumulative genetic risk estimations in multiple sclerosis (MS) successfully tracked the aggregation of susceptibility variants in multi-case and single-case families. It used a limited description of susceptibility loci available at the time (17 loci). Even though the full roster of MS risk genes remains unavailable, we estimated the genetic burden in MS families and assess its disease predictive power using up to 64 single-nucleotide polymorphism (SNP) markers according to the most recent literature. A total of 708 controls, 3251 MS patients and their relatives, as well as 117 twin pairs were genotyped. We validated the increased aggregation of genetic burden in mult…
