Chromosomal changes in renal oncocytomas Evidence that t(5;11)(q35;q13) may characterize a second subgroup of oncocytomas
1995
Many of the reported oncocytomas have different chromosome abnormalities, indicating that they comprise a cytogenetically heterogenous group of tumors consisting of potentially cytogenetic subgroups. We have performed cytogenetic studies on nine renal oncocytomas. Clonal abnormalities were present in eight tumors. The findings most observed were the loss of the Y chromosome, and abnormalities of chromosomes 1 and 22. We also observed telomeric associations (tas) in two tumors and structural aberrations of chromosomes 9p and 19q, as well as monosomy 10. In two cases we found a similar reciprocal t(5;11)(q35;q13) in two cases. Review of the literature disclosed one other oncocytoma with a t(5…
Total energy expenditure is repeatable in adults but not associated with short-term changes in body composition
2022
Low total energy expenditure (TEE, MJ/d) has been a hypothesized risk factor for weight gain, but repeatability of TEE, a critical variable in longitudinal studies of energy balance, is understudied. We examine repeated doubly labeled water (DLW) measurements of TEE in 348 adults and 47 children from the IAEA DLW Database (mean ± SD time interval: 1.9 ± 2.9 y) to assess repeatability of TEE, and to examine if TEE adjusted for age, sex, fat-free mass, and fat mass is associated with changes in weight or body composition. Here, we report that repeatability of TEE is high for adults, but not children. Bivariate Bayesian mixed models show no among or within-individual correlation between body c…
Physical activity and fat-free mass during growth and in later life.
2021
ABSTRACT Background Physical activity may be a way to increase and maintain fat-free mass (FFM) in later life, similar to the prevention of fractures by increasing peak bone mass. Objectives A study is presented of the association between FFM and physical activity in relation to age. Methods In a cross-sectional study, FFM was analyzed in relation to physical activity in a large participant group as compiled in the International Atomic Energy Agency Doubly Labeled Water database. The database included 2000 participants, age 3–96 y, with measurements of total energy expenditure (TEE) and resting energy expenditure (REE) to allow calculation of physical activity level (PAL = TEE/REE), and cal…
Influence of Guideline Operationalization on Youth Activity Prevalence in the International Children's Accelerometry Database
2022
Introduction: The United Kingdom and World Health Organization recently changed their youth physical activity (PA) guidelines from 60 minutes of moderate-vigorous PA (MVPA) every day, to an average of 60 minutes of MVPA per day, over a week. The changes are based on expert opinion due to insufficient evidence comparing health outcomes associated with different guideline definitions. Further, inconsistent guideline operationalization impairs understanding of physical inactivity prevalence. This study used the International Children’s Accelerometry Database to compare approaches to calculating PA compliance among youth and associations with health indicators. Methods: Cross-sectional accelero…
The role of the results of functional tests and psychological factors on prediction of injuries in adolescent female football players
2021
Football is a popular sport among adolescent females. Given the rate of injuries in female footballers, identifying factors that can predict injuries are important. These injuries are often caused by complex reasons. The aim of this study was to investigate if the combination of demographic (age, number of training and match play hours/week), psychosocial (perceived stress, adaptive coping strategies) and physiological factors (functional performance) can predict a traumatic injury in adolescent female footballers. A cohort consisting of 419 female football players aged 13–16 years was established. Baseline questionnaires covered potential risk factors for sport injuries, and measurem…
Healthy and unhealthy eating after a behaviour change intervention in primary care
2022
Abstract Background: To prevent and reduce non-communicable diseases, the Norwegian Directorate of Health encourages Healthy Life Centres (HLCs) in all municipalities. Aims: This study investigates whether the behaviour change interventions at HLCs positively affected participants’ diet and to evaluate predictors for healthy and unhealthy eating. Our data are part of the Norwegian Healthy Life Centre Study, a 6-month, pragmatic randomised controlled trial (RCT). Methods: Totally, 118 participants ≥18 years old were randomised to an intervention group (n 57), or a waiting list (control group) (n 61). Eighty-six participants met at the 6 months follow-up visit. We merged the participants to o…
The influence of change on sense of coherence on dental services use among adolescents: a two-year prospective follow-up study.
2021
Abstract Background To investigate the influence of change on sense of coherence (SOC) on dental services use in adolescents over a two-year period. Methods A prospective follow-up study was conducted involving 334 12-year-old adolescents from public schools in the city of Manaus, Amazonas, Brazil. The predictors of use of dental services in the last 12 months were selected according to the Andersen’s behavioural theoretical model. The predisposing factors included sex, self-reported skin colour and SOC. The enabling factors were dental insurance, monthly family income and parents/guardians schooling. Dental pain, perceived oral health status, dental caries and gingival status were used to …
Daily steps and all-cause mortality: a meta-analysis of 15 international cohorts
2022
BACKGROUND: Although 10 000 steps per day is widely promoted to have health benefits, there is little evidence to support this recommendation. We aimed to determine the association between number of steps per day and stepping rate with all-cause mortality. METHODS: In this meta-analysis, we identified studies investigating the effect of daily step count on all-cause mortality in adults (aged ≥18 years), via a previously published systematic review and expert knowledge of the field. We asked participating study investigators to process their participant-level data following a standardised protocol. The primary outcome was all-cause mortality collected from death certificates and country regi…
Adolescents’ and young adults’ transition experiences when transferring from paediatric to adult care: A qualitative metasynthesis

SARS-CoV-2 antibody persistence after five and twelve months: A cohort study from South-Eastern Norway
2022
Objectives To assess total antibody levels against Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS CoV-2) spike protein up to 12 months after Coronavirus Disease (COVID-19) infection in non-vaccinated individuals and the possible predictors of antibody persistence. Methods This is the first part of a prospective multi-centre cohort study. Participants The study included SARS-CoV-2 real-time polymerase chain reaction (RT-PCR) positive and negative participants in South-Eastern Norway from February to December 2020. Possible predictors of SARS-CoV-2 total antibody persistence was assessed. The SARS-CoV-2 total antibody levels against spike protein were measured three to five months aft…
