Virulent synergistic effect between Enterococcus faecalis and Escherichia coli assayed by using the Caenorhabditis elegans model.

2008

5 pages; International audience; BACKGROUND: The role of enterococci in the pathogenesis of polymicrobial infections is still debated. The purpose of this study was to evaluate the effect of virulent enterococci in the presence or absence of Escherichia coli strains in the in vivo Caenorhabditis elegans model. PRINCIPAL FINDINGS: This study demonstrated that there was a synergistic effect on virulence when an association of enterococci and E. coli (LT50 = 1.6 days+/-0.1 according to the tested strains and death of nematodes in 4 days+/-0.5) was tested in comparison with enterococci alone (LT50 = 4.6 days+/-0.1 and death in 10.4 days+/-0.6) or E. coli alone (LT50 = 2.1+/-0.9 and deaths 6.6+/…

Influence of cell proportions and proliferation rates on FDG uptake in squamous-cell esophageal carcinoma: a PET study.

2008

We investigated the influence of cell proportions and proliferation activities on tumor maximum standard uptake value (SUV(max)) in patients with squamous-cell esophageal cancer (SCEC).Sixteen (16) patients with untreated SCEC were examined with (18)F-flourodeoxyglucose positron emission tomography (FDG-PET). The tumor SUV(max) were calculated. Tumors were resected by transthoracic esophagectomy. Tissues were stained with hematoxylin and eosin for the measurement of cell proportions and MIB-1 for measurement of proliferation indices (PIs). Tumor SUV and histologic data were related by using multiple linear regression analysis.The mean proportion of tumor cells in the tumor site was 58.1% (+…

Age and sex related changes in episodic memory function in middle aged and older adults

2014

Age-related change in episodic memory function is commonly reported in older adults. When detected on neuropsychological tests, it may still be difficult to distinguish normal from pathological changes. The present study investigates age-and sex-related changes in a group of healthy middle-aged and older adults, participating in a three-wave study on cognitive aging. The California Verbal Learning test (CVLT-II) was used to assess their episodic memory function. A cross-sectional analysis of results from the first wave showed higher performance in females than males, with a steeper age-related decline in males. This was confirmed in a longitudinal analysis using a mixed effects regression m…

Unmet care needs are common among community-dwelling older people with memory problems in Finland

2019

Aims: Ageing in place has become a policy priority. Consequently, residential care has been reduced, and more older people with multiple care needs reside at home with the help of informal care and home care services. An increasing share of these people has memory disorders. We examined the extent to which memory problems, in addition to other individual characteristics, are associated with unmet care needs among community-dwelling older people. Methods: The study employed cross-sectional survey data from community-dwelling people aged 75+ collected in 2010 and 2015, analysed using binary logistic regression analysis. The study population consisted of people who had long-term illnesses or …

Physical Activity and Self-Rated Health among 55- to 89-Year-Old Dutch People

1999

The aim of this study was to examine the effects of physical activity and the possible mediating role of perceived physical self-efficacy (PPSE) on self-rated health (SRH) in the 55- to 89-year-old Dutch population. The data are based on a structured interview carried out in a random sample of 120 subjects-60 men and 60 women with the average ages of 69 and 71 years, respectively-in Sassenheim, the Netherlands, as a pilot study of the Longitudinal Aging Study Amsterdam (LASA). The results of linear multiple regression analyses showed that physical activity was a significant predictor of self-rated health. Moreover, the results supported the role of PPSE as a mediator in the association bet…

Role of TGF-β Pathway Polymorphisms in Sporadic Thoracic Aortic Aneurysm: rs900 TGF-β2 Is a Marker of Differential Gender Susceptibility

2013

Thoracic aortic aneurysm (TAA) is a progressive disorder involving gradual dilation of ascending and/or descending thoracic aorta with dissection or rupture as complications. It occurs as sporadic or defined syndromes/familial forms.Genetic, molecular and cellular mechanims of sporadic TAA forms are poorly characterized and known. Thus, our interest has been focused on investigating the role of genetic variants of transforming growth factor-β(TGF-β) pathways in TAA risk. On the other hand, no data on the role of genetic variants of TGF-βpathway in sporadic TAA exist until now. In addition, other cytokines, including IL-10, orchestrate TAA pathophysiology. Their balance determines the ultima…

Air pollution and childhood leukaemia: a nationwide case-control study in Italy

2013

Objectives Leukaemia is the most common cancer in children, but its aetiology is still poorly understood. We tested the hypothesis that traffic-related air pollution is associated with paediatric leukaemia because of chronic exposure to several potential carcinogens. Methods The Italian SETIL study (Study on the aetiology of lymphohematopoietic malignancies in children) was conducted in 14 Italian regions. All incident cases of leukaemia in children aged ≤10 years from these regions (period 1998–2001) were eligible for enrolment. Two controls per case, matched on birth date, gender and region of residence were randomly selected from the local population registries. Exposure assessment at bi…

Trends in the prevalence of asthma and allergic rhinitis in Italy between 1991 and 2010

2012

The prevalence of asthma increased worldwide until the 1990s, but since then there has been no clear temporal pattern. The present study aimed to assess time trends in the prevalence of current asthma, asthma-like symptoms and allergic rhinitis in Italian adults from 1990 to 2010. The same screening questionnaire was administered by mail or phone to random samples of the general population (age 20-44 yrs) in Italy, in the frame of three multicentre studies: the European Community Respiratory Health Survey (ECRHS) (1991-1993; n=6,031); the Italian Study on Asthma in Young Adults (ISAYA) (1998-2000; n=18,873); and the Gene Environment Interactions in Respiratory Diseases (GEIRD) study (2007-2…

Validation of two portable bioelectrical impedance analyses for the assessment of body composition in school age children

2017

Background Bioelectrical impedance analysis (BIA) is a convenient and child-friendly method for longitudinal analysis of changes in body composition. However, most validation studies of BIA have been performed on adult Caucasians. The present cross-sectional study investigated the validity of two portable BIA devices, the Inbody 230 (BIA8MF) and the Tanita BC-418 (BIA8SF), in healthy Taiwanese children. Methods Children aged 7–12 years (72 boys and 78 girls) were recruited. Body composition was measured by the BIA8SF and the BIA8MF. Dual X-ray absorptiometry (DXA) was used as the reference method. Results There were strong linear correlations in body composition measurements between the BIA…
