Low-dose vitamin D supplementation and incident frailty in older people: An eight year longitudinal study.
2018
Hypovitaminosis D is associated with frailty, but if vitamin D supplementation may prevent the onset of frailty is poorly known. Therefore, we aimed to investigate whether vitamin D supplementation is associated with a lower risk of frailty. In this longitudinal study, 4,421 individuals at high risk or having knee osteoarthritis free from frailty at baseline (mean age: 61.3, females = 58.0%) were followed for 8 years. Details regarding vitamin D supplementation were captured by asking whether the participant took vitamin D during the previous year, at least once per month. Frailty was defined using the Study of Osteoporotic Fracture (SOF) index as the presence of at least two of the followi…
Trajectories of mobility limitations over 24 years and their characterization by shift work and leisure-time physical activity in midlife.
2019
Abstract Background We aimed to investigate trajectories of mobility limitations (MLs) over a period of 24 years. In addition, we aimed to study how shift work and leisure-time physical activity (LTPA) in midlife predict assignment to MLs trajectories separately for those retired on statutory pensions (SPs) and on disability pensions (DPs). Methods Subjects who responded MLs questionnaires (1985–2009, N = 3048) in Finnish Longitudinal Study on Aging Municipal Employees were included in this prospective cohort study. LTPA and shift work were measured during baseline. International Classification of Functioning was used to code MLs. Growth mixture modeling was used to identify the trajectorie…
The Healthy Nordic Diet and Mediterranean Diet and Incidence of Disability 10 Years Later in Home-Dwelling Old Adults.
2019
Background/Objective: Diet has a major impact on a person's health. However, limited information exists on the long-term role of the whole diet on disability. We investigated the association of the healthy Nordic diet and the Mediterranean diet with incident disability 10 years later. Design: Longitudinal, with a follow-up of 10 years. Settings/Participants: A total of 962 home-dwelling men and women from the Helsinki Birth Cohort Study, mean age 61.6 years, who were free of disability at baseline. Measurements: At baseline, 2001-2004, the Nordic diet score (NDS) and modified Mediterranean diet score (mMDS) were calculated using a validated 128-item food-frequency questionnaire. Higher scor…
Physical inactivity and pain in older men and women with hip fracture history
2011
Hip fracture patients often suffer from pain for several months after surgery. This may lead to physical inactivity and subsequent mobility limitation and disability. The purpose of this study was to investigate the association between severe musculoskeletal pain and the level of physical activity in older people with a history of hip fracture. Data were collected from 60- to 85-year-old (n = 78) community-dwelling people, 0.7–7.5 years after hip fracture. Physical activity was assessed with the Yale Physical Activity Survey (YPAS). According to the YPAS summary index distribution, the participants were divided into the physically inactive and physically active groups. Musculoskeletal pain …
Vector Transmission of a Plant-Pathogenic Bacterium in the Arsenophonus Clade Sharing Ecological Traits with Facultative Insect Endosymbionts
2009
Bressan, A., Semetey, O., Arneodo, J., Lherminier, J., and BoudonPadieu, E. 2009. Vector transmission of a plant-pathogenic bacterium in the Arsenophonus clade sharing ecological traits with facultative insect endosymbionts. Phytopathology 99:1289-1296. The planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) is the major vector of a nonculturable plant-pathogenic γ-3 proteobacterium associated with a disease of sugar beet called syndrome “basses richesses” (SBR). The bacterium, here called SBR bacterium, belongs to the Arsenophonous clade, which includes mostly insect-associated facultative symbionts. Assays using field-collected planthopper nymphs and adults were carried out to inve…
Rapid mycotoxin analysis in human urine: A pilot study
2011
A simple and rapid method effective for quantitative determination of deoxynivalenol (DON), T-2 toxin (T-2), HT-2 toxin (HT-2), zearalenone (ZEN), ochratoxin A (OTA), aflatoxins (AFs) B(1), B(2), G(1) and G(2) and fumonisins FB(1) and FB(2) in urine was developed. The urine was diluted with phosphate buffer solution (PBS) and thoroughly mixed. For clean-up and extraction, the mixture was loaded on a MYCO 6in1 IAC. Hybrid triple quadrupole-linear ion trap mass spectrometer (QTrap) was used for the detection. Extra tools for confirmation of selected mycotoxins in positive samples, Information Dependent Acquisition (IDA) experiments, were also developed. The use of immunoaffinity columns follo…
Closed loop stimulation improve ejection fraction in pediatric patients with pacemaker and ventricular dysfunction
2007
Background: The aim of this prospective study was to evaluate the effect of the closed loop stimulation (CLS) on the ejection fraction in pediatric patients, affected by complete atrioventricular block (CAVB) or CAVB and sinus node dysfunction (SND), with a previously implanted pacemaker (PM) and ventricular dysfunction. The role of electrical therapy in the treatment of pediatric patients with congenital atrioventricular (AV) blocks has been shown. Conventional right ventricular pacing seems to affect ventricular function. Up to now, the feasibility and the long-term results of biventricular pacing in pediatric patients were not entirely clear. Methods: In eight pediatric patients with a p…
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…
Ketogenic diet for infants with epilepsy: A literature review.
2020
Abstract The ketogenic diet (KD) is an established, nonpharmacological treatment for drug-resistant epilepsy (DRE). Actually, KD and its variants have been shown to be elective and resolute for patients with glucose transporter type 1 (GLUT1) deficiency. The aim of this review was to study the use of KD and its variants in infancy, including the neonatal age, and demonstrate the safety and efficacy of this treatment in patients with the age of 0–23 months affected by DRE already subjected to pharmacological approach attempts. A literature search was conducted using PubMed as the medical database source. We used the age limit of 0–23 months, and we considered only articles published between …
Cost of reproduction in Callosobruchus maculatus: effects of mating on male longevity and the effect of male mating status on female longevity.
2005
One of the most studied life-history trade-offs is that resulting from the cost of reproduction: a trade-off arises when reproduction diverts limited resources from other life-history traits. We examine the cost of reproduction in male, and the effect of male mating status on female Callosobruchus maculatus seed beetles. Cost of reproduction for male C. maculatus was manifested as reduced longevity. There was also a positive relationship between male body size and male longevity. Females mated to males that had already copulated twice did not live as long as females mated to males that had copulated once or not at all. The third copulation of males also lasted longer than the two previous o…
