Avian malaria (Plasmodium spp.) and other blood parasitic infections of birds constitute increasingly popular model systems in ecological and evolutionary host-parasite studies. Field studies of these parasites commonly use two traits in hypothesis testing: infection status (or prevalence at the population level) and parasitaemia, yet the causes of variation in these traits remain poorly understoo
Objective: Prior studies investigating the association between APOE alleles epsilon 2/epsilon 4 and risk of intracerebral hemorrhage (ICH) have been inconsistent and limited to small sample sizes, and did not account for confounding by population stratification or determine which genetic risk model was best applied. Methods: We performed a large-scale genetic association study of 2189 ICH cases an
Background: Self-injury, a manifestation of severe psychological distress, is increased in cancer-bereaved youths. Little is known about the potential influence on the risk for self-injury of factors that could be clinically relevant to and modifiable by the health-care professionals involved in the care of the dying parent. Methods: In a nationwide population-based anonymous study, 622 (73.1%) yo
Nitrogen (N) cycle dynamics and N deposition play an important role in determining the terrestrial biosphere's carbon (C) balance. We assess global and biome-specific N deposition effects on C sequestration rates with the dynamic global vegetation model LPJ-GUESS. Modeled CN interactions are evaluated by comparing predictions of the C and CN version of the model with direct observations of C fluxe
Background and goals: Comparing cancer incidence by migrant studies is one of the main approaches to generate hypotheses on the aetiology of cancer. Immigrant studies are most informative when cancer incidence data are available from both the Source and the host country. Methods: The age standardised incidence rate (ASR) and standardised incidence ratio (SIR) of cancers among the Iranian immigrant
BACKGROUND AND PURPOSE: In failed total ankle replacements (TARs), fusion is often the procedure of preference; the outcome after exchanging prosthetic components is debated. We analyzed prosthetic survival, self-reported function, and patient satisfaction after component exchange. Patients and methods We identified patients in the Swedish Ankle Registry who underwent exchange of a tibial and/or t
Background: Little is known of the association between thyroid hormones in the central nervous system and Alzheimer's disease (AD). We determined thyroid hormone levels in serum and cerebrospinal fluid (CSF) in a well-defined homogeneous mono-center population. Methods: Fifty-nine consecutive patients under primary evaluation for cognitive impairment were recruited. The participants included patie
The diagnosis of malignant mesothelioma in serosal effusions continues to he a major challenge because some of its cytomorphological features closely resemble adenocarcinomas. Immunohistochemistry is a valuable tool in the differentiation of epithelioid mesothelioma from metastatic adenocarcinomas. However, no single antibody has demonstrated absolute sensitivity or specificity. In this study, we
BACKGROUND: Decreased glomerular filtration rate is an established risk factor for bleeding but there are limited data on its association with bleeding risk in well-controlled anticoagulated patients taking warfarin. OBJECTIVES: The aim was to investigate the relationship between glomerular filtration rate, major bleeding and thromboembolic complications in patients with tight anticoagulation cont
Introduction: The objective of the study was to investigate the impact of newer biologic treatments including rituximab, abatacept and tocilizumab on antibody response following pneumococcal vaccination using a 7-valent conjugate vaccine in patients with established rheumatoid arthritis (RA). Methods: Patients with RA receiving rituximab, abatacept or tocilizumab as monotherapy or combined with me
The familial risk of medullary thyroid carcinoma (MTC alone or as part of multiple endocrine neoplasms, MEN2A/MEN2B) is high, so we aimed to answer open questions about the lifetime cumulative risk of thyroid cancer (LCRTC at 0-79 years) among relatives of MTC patients by age and sex. For this nationwide study, a cohort of 3217 first-/second-degree relatives (FDRs/SDRs) of 389 MTC patients diagnos
Background: Early diagnosis of breast cancer treatment-related lymphedema (BCRL) is of great importance for longstanding treatment results. Tissue dielectric constant (TDC) and bioimpedance spectroscopy (BIS) both have a potential for early diagnosis, but have not been compared. Methods and Results: One hundred women, treated for breast cancer with breast surgery, axillary dissection, and radiothe
Postprandial lipemia varies with composition of dietary fat due to partitioning of fatty acids between beta-oxidation, incorporation into TAG, and tissue lipids. Effects of alpha-linolenic acid (ALA) are poorly characterized. Lipase-catalyzed transesterification was used to produce a novel ALA-oil (35% ALA) from rapeseed and linseed oil. We hypothesized a lower postprandial lipemic response with A
Human papillomaviruses (HPV) are established as a major cause of cervical carcinoma. However, causality inference is dependent on prospective evidence showing that exposure predicts risk for future disease. Such evidence is available for squamous cell carcinoma, but not for cervical adenocarcinoma. We followed a population-based cohort of 994,120 women who participated in cytological screening in
Venous thromboembolism (VTE) and arterial thrombosis have been thought to result from two different mechanisms. Recent data indicate that the two diseases may share some common risk factors, such as the activity of inflammation on haemostasis. In this population-based study we explored whether raised levels of inflammation-sensitive plasma markers (ISPs) increase the risk for venous thromboembolis
Background The incidence of hematologic cancers increases with age. These cancers are associated with recurrent somatic mutations in specific genes. We hypothesized that such mutations would be detectable in the blood of some persons who are not known to have hematologic disorders. Methods We analyzed whole-exome sequencing data from DNA in the peripheral-blood cells of 17,182 persons who were uns
BACKGROUND: Asthma may be defined either as wheeze within the previous 12 months (current wheeze) doctor-diagnosed asthma (DDA), or current wheeze plus confirmed airway hyperresponsiveness (AHR). AIMS: We wanted to estimate asthma prevalence in randomly selected adolescents based on different criteria for asthma diagnosis, study gender differences in reported asthma-like symptoms vs DDA, and relat
BACKGROUND: Persistent organochlorine pollutants (POPs) may interfere with reproductive function but direct evidence in humans is very limited. METHODS: Fertility was examined in four regions with contrasting blood levels of POPs. Pregnant women and their partners in Warsaw (Poland), Kharkiv (Ukraine) and Greenland were consecutively enrolled during antenatal visits. Swedish fishermen and their sp
OBJECTIVE - To study the effect of the short-acting insulin secretagogue nateglinide in patients with maturity-onset diabetes of the young type 3 (MODY3), which is characterized by a defective insulin response to glucose and hypersensitivity to sulfonylureas. RESEARCH DESIGN AND METHODS - We compared the acute effect of nateglinide, glibenclamide, and placebo on prandial plasma glucose and serum i
