Invasive group B streptococcal infections in Finland: a population-based study

We analyzed surveillance data on group B streptococcus (GBS) infection in Finland from 1995 to 2000 and reviewed neonatal cases of early-onset GBS infection in selected hospitals in 1999 to 2000. From 1995 to 2000, 853 cases were reported (annual incidence 2.2-3.0/100,000 population). We found 32-38 neonatal cases of early-onset GBS disease per year (annual incidence 0.6-0.7/1,000 live births). In five hospitals, 35% of 26 neonatal cases of early-onset GBS infection had at least one risk factor: prolonged rupture of membranes, preterm delivery, or intrapartum fever. Five of eight mothers screened for GBS were colonized. In one case, disease developed despite intrapartum chemoprophylaxis. Although the incidence of early-onset GBS disease in Finland is relatively low, some geographic variation exists, and current prevention practices are suboptimal. Establishing national guidelines to prevent perinatal GBS is likely to reduce the incidence of the disease.     

Secular trend in candidemia and the use of fluconazole in Finland, 2004-2007

Background  

In a previous study we observed an increasing trend in candidemia in Finland in the 1990s. Our aim was now to investigate further population-based secular trends, as well as outcome, and evaluate the association of fluconazole consumption and prophylaxis policy with the observed findings.     

A 3-D model-based registration approach for the PET,MR and MCG cardiac data fusion

In this paper, a new approach is presented for the assessment of a 3-D anatomical and functional model of the heart including structural information from magnetic resonance imaging (MRI) and functional information from positron emission tomography (PET) and magnetocardiography (MCG). The method uses model-based co-registration of MR and PET images and marker-based registration for MRI and MCG. Model-based segmentation of MR anatomical images results in an individualized 3-D biventricular model of the heart including functional parameters from PET and MCG in an easily interpretable 3-D form.     

Enzymic degradation of a beta-lactam antibiotic,ampicillin, in the gut: a novel treatment modality

Antibiotics can cause severe alterations in the gut microflora and promote diarrhoea and overgrowth of pathogenic bacteria. The present study investigated the potency of targeted recombinant beta-lactamase (TRBL) to degrade a beta-lactam antibiotic in the jejunum of fistula-operated beagles. We used different peroral doses of purified beta-lactamase (PenP) of Bacillus licheniformis in enteric-coated pellets together with intravenous ampicillin. Serum and jejunal samples were collected for ampicillin and beta-lactamase analysis. A dose-response effect of TRBL on ampicillin concentrations in the jejunal samples could be observed. The highest doses applied decreased the jejunal ampicillin concentrations to undetectable levels. In the serum samples, the ampicillin concentrations were not affected by the beta-lactamase dose used. Our results indicate that it may be possible to evolve a targeted treatment to degrade beta-lactam antibiotics intestinally and, thus, decrease antibiotic-induced adverse effects on the gut microflora.     

Reliability and validity of the Finnish version of the Lower Extremity Functional Scale (LEFS)

Purpose: The present study aimed to assess the psychometric properties of the Finnish version of the Lower Extremity Functional Scale (LEFS) among foot and ankle patients.

Methods: The LEFS was translated and cross-culturally adapted to Finnish. We assessed the test–retest reliability, internal consistency, floor-ceiling effect, construct validity and criterion validity in patients who underwent surgery due to musculoskeletal pathology of the foot and ankle (N?=?166).

Results: The test–retest reliability was high (ICC = 0.93, 95% CI: 0.91–0.95). The standard error of measurement was 4.1 points. The Finnish LEFS showed high internal consistency (Cronbach’s α?=?0.96). A slight ceiling effect occurred as 17% achieved the maximum score. The LEFS correlation was strong with the 15D Mobility dimension (r?=?0.74) and overall HRQoL (r?=?0.66), pain during foot and ankle activity (r=??0.69) and stiffness (r=??0.62). LEFS correlated moderately with foot and ankle pain at rest (r=??0.50) and with physical activity (r?=?0.46).

Conclusions: The Finnish version of the LEFS showed reliability and validity comparable to those of the original version. This study indicates that the Finnish version of the LEFS serves both clinical and scientific purposes in assessing lower-limb function.

• Implications for Rehabilitation

• The Finnish version of the Lower Extremity Functional Scale (LEFS) is a reliable and valid tool for assessing lower-extremity musculoskeletal disability in Finnish-speaking population.

• Investigation of the psychometric properties of the Finnish version of the LEFS showed validity and reliability comparable to those of the original English version.

• The Finnish LEFS is easy to complete and suitable for clinical, rehabilitation and research purposes.

     

Qualitative study of social and healthcare educators’ perceptions of their competence in education

Competent educators are needed to ensure that social and healthcare professionals are effective and highly competent. However, there is too little evidence‐based knowledge of current and required enhancements of educators' competences in this field. The aim of this study was to describe social and healthcare educators’ perceptions of their competence in education. The study had a qualitative design, based on interviews with educators and rooted in critical realism. Forty‐eight participants were recruited from seven universities of applied sciences and two vocational colleges in Finland, with the assistance of contact persons nominated by the institutions. The inclusion criterion for participation was employment by an educational institution as a part‐time or full‐time, social and/or healthcare educator. Data were collected in the period February–April 2018. The participants were interviewed in 16 focus groups with two to five participants per group. The acquired data were subjected to inductive content analysis, which yielded 506 open codes, 48 sub‐categories, nine categories and one main category. The educators’ competence was defined as a multidimensional construct, including categories of educators’ competences in practicing as an educator, subject, ethics, pedagogy, management and organisation, innovation and development, collaboration, handling cultural and linguistic diversity, and continuous professional development. Educators recognised the need for developing competence in innovation to meet rapid changes in a competitive and increasingly global sociopolitical environment. Enhancement of adaptability to rapid changes was recognised as a necessity. The findings have social value in identifying requirements to improve social and healthcare educators' competence by helping educational leadership to improve educational standards, construct a continuous education framework and create national and/or international curricula for teacher education degree programs to enhance the quality of education. We also suggest that educational leadership needs to establish, maintain and strengthen collaborative strategies to provide effective, adaptable support systems, involving educators and students, in their working practices.     

Missense mutations to the TSC1 gene cause tuberous sclerosis complex

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterised by the development of hamartomas in a variety of organs and tissues. The disease is caused by mutations in either the TSC1 gene on chromosome 9q34 or the TSC2 gene on chromosome 16p13.3. The TSC1 and TSC2 gene products, TSC1 and TSC2, interact to form a protein complex that inhibits signal transduction to the downstream effectors of the mammalian target of rapamycin (mTOR). Here we investigate the effects of putative TSC1 missense mutations identified in individuals with signs and/or symptoms of TSC on TSC1-TSC2 complex formation and mTOR signalling. We show that specific amino-acid substitutions close to the N-terminal of TSC1 reduce steady-state levels of TSC1, resulting in the activation of mTOR signalling and leading to the symptoms of TSC.
