BACKGROUND: Mycoplasma pneumoniae (MP) causes epidemics of upper respiratory disease and pneumonia. It is thought that MP usually causes milder upper respiratory disease in pre-school children, with a greater chance of pneumonia in school-age children. In this population-based cross-sectional study, we present evidence that severe MP infection is more common in pre-school children than previously thought. METHODS: During an MP epidemic in our area widespread health service and public awareness lead to extensive testing for MP...

BACKGROUND: In order to determine the relative biological effectiveness (RBE) of protons with high accuracy, radiobiological experiments with detailed knowledge of the linear energy transfer (LET) are needed. Cell survival data from high LET protons are sparse and experiments with low energy protons to achieve high LET values are therefore required. The aim of this study was to quantify LET distributions from a low energy proton beam by using Monte Carlo (MC) simulations, and to further compare to a proton beam representing a typical minimum energy available at clinical facilities...

Background: Whereas the association between social support and psychological distress has been well-established through both cross-sectional and longitudinal studies, less is known about whether social support influences rate of change in psychological distress over time. Nor is it clear whether social support predicts baseline psychological distress, or, more importantly, whether social support may contribute to more rapid recovery following trauma exposure. Objective: This study aimed to determine the extent to which social support contributed to the recovery process among individuals with psychological distress after being exposed to trauma...

BACKGROUND: Primary infection with Toxoplasma gondii during pregnancy may pose a threat to the fetus. Women infected prior to conception are unlikely to transmit the parasite to the fetus. If maternal serology indicates a possible primary infection, amniocentesis for toxoplasma PCR analysis is performed and antiparasitic treatment given. However, discriminating between primary and latent infection is challenging and unnecessary amniocenteses may occur. Procedure-related fetal loss after amniocentesis is of concern...

BACKGROUND/AIMS: In the quest for prevention or treatment, there is a need to find early markers for preclinical dementia. This study observed memory clinic patients with subjective cognitive impairment (SCI) and normal cognitive function at baseline. The primary aim was to address SCI as a potential risk factor for cognitive decline. The secondary aim was to address a potential relation between (1) baseline cerebrospinal fluid biomarkers and (2) a decline in memory performance over the first 2 years of follow-up, with a possible cognitive decline after 6 years...

BACKGROUND: Precision cancer medicine depends on defining distinct tumour subgroups using biomarkers that may occur at very modest frequencies. One such subgroup comprises patients with exceptionally mutated (ultramutated) cancers caused by mutations that impair DNA polymerase epsilon (POLE) proofreading. METHODS: We examined the association of POLE proofreading domain mutation with clinicopathological variables and immune response in colorectal cancers from clinical trials (VICTOR, QUASAR2, and PETACC-3) and colorectal cancer cohorts (Leiden University Medical Centre 1 and 2, Oslo 1 and 2, Bern, AMC-AJCC-II, and Epicolon-1)...

Persistent organic pollutants (POPs) are chemical compounds of environmental concern due to their toxic, persistent nature and their ability to bio-accumulate in biological tissue. Seabirds, for often being at the top of the food web, have been used as monitors of environmental pollutants. Adverse effects caused by POPs have been reported in common terns (Sterna hirundo) since the 1970s. Egg shell thinning, embryo and hatchling deformities have been reported for this species. Environmental legislation, such as the Oslo-Paris Convention (OSPAR), has agreed on the monitoring of concentration of POPs in common terns...

Liver transplantation for metastatic neuroendocrine tumor (NET) in the liver used to be the main reason for liver transplantation for metastatic liver tumor. It is reported that liver transplantation in selected patients with nonresectable metastatic NET in the liver had favorable outcomes equivalent to liver transplantation for hepatocellular carcinoma. Recently, liver transplantation for colorectal liver metastasis (CRLM) has attracted attention. According to the SECA study in Oslo, liver transplantation for non-resectable CRLM had a high rate of recurrence but a favorable prognosis...
