OBJECTIVES: Telomeres are critical to maintain the integrity of the chromosomes, and telomere abnormalities are important features of carcinogenesis. Telomere length differs among individuals due to genetic and environmental factors. Aiming to examine the relationship between DNA-damaging agents and average telomere length in peripheral blood, we conducted a cross-sectional study among 157 workers
PURPOSE Cancer of unknown primary (CUP) is diagnosed at the metastatic stage, and despite extensive diagnostic work-up, the primary tumor often remains unidentified. No data are available on familial clustering of CUP. We hypothesize that familial clustering of CUP with other cancers may be informative of the primary sites. PATIENTS AND METHODS A total of 35,168 patients with CUP were identified i
AIM: To characterize the colon microbiota in two women histologically diagnosed with collagenous colitis using a culture-independent method. METHODS: Biopsies were taken from the ascending colon and the total DNA was extracted. Universal bacterial primers were used to amplify the bacterial 16S rRNA genes. The amplicons were then cloned into competent Escherichia coli cells. The clones were sequen
Clinicians may record patients presenting with osteoarthritis (OA) symptoms with joint pain rather than an OA diagnosis. This may have implications for OA research studies and patient care. The objective was to assess whether older adults recorded with joint pain are similar to those with a recorded OA diagnosis.
PURPOSE An overwhelming majority of data on familial risk in cancer is based on incident cancer, whereas familiality in cancer mortality is largely unknown. If fatal form of cancer was a highly familial subtype, then familial risk for mortality may exceed that of incidence, which would be particularly relevant for clinical decision making and counseling. PATIENTS AND METHODS The individuals in the
OBJECTIVE: To study how the incidence of cancer is related to diabetes, obesity or abnormal blood lipids. METHODS: Diagnosis of diabetes, obesity or abnormal blood lipids was studied 0-10 years prior to the diagnosis of cancer in 19,756 cases of cancer and in 147,324 controls matched regarding age, sex and domicile. RESULTS: Diabetes was significantly more common prior to diagnosis in patients w
In humans, mast cells are ubiquitously present in tissues adjacent to external environment and consequently have an important sentential role in host defence, homeostasis and repair. Their key role in allergen-mediated conditions has been recognized for many decades already. So far, therapies targeting mast cells offered clinical efficacy in allergic conditions except for asthma. More recently, so
Summary Proteinase 3 (PR3) is a major autoantigen in anti-neutrophil cytoplasmic antibodies (ANCA)-associated systemic vasculitis (AASV), and the proportion of neutrophils expressing PR3 on their membrane (mPR3(+)) is increased in AASV. We have shown recently that mPR3 and CD177 are expressed on the same cells in healthy individuals. In this study we try to elucidate mechanisms behind the increase
BACKGROUND: Exhaustion is a concept of interest for both occupational health research and stress-disease theory research. The aim of the present study was to explore associations between chronic stressors, in terms of psychosocial working conditions, and exhaustion in a Swedish middle-aged population sample. METHODS: A vocationally active population sample of the Malmö Shoulder and Neck Study coho
Madelung A, Bzorek M, Bondo H, Zetterberg E, Bjerrum O W, Hasselbalch H C, Scheding S & Ralfkiaer E (2012) Histopathology A novel immunohistochemical sequential multi-labelling and erasing technique enables epitope characterization of bone marrow pericytes in primary myelofibrosis Aim: In Philadelphia (Ph)-negative chronic myeloproliferative neoplasms, increased microvascular density, bizarre
PURPOSE: Whether childhood adrenocortical tumors (ACTs), choroid plexus tumors (CPTs), and rhabdomyosarcoma (RMS) are early manifestation of Li-Fraumeni syndrome (LFS) is uncertain. In this study, we evaluated the frequency of germline TP53 mutations and family history in a population-based series of patients. PATIENTS AND METHODS: We identified children (≤18 years) diagnosed between 1958 and
Stroke-induced neurogenesis originates from a neural stem cell (NSC) niche in subventricular zone (SVZ). In mice, NSCs are concentrated in a so-called "neurogenic spot" in the lateral angle area of SVZ. We aimed to identify the "neurogenic spot" in the rat SVZ and to characterize the cellular changes in the ependymal cell compartment in this area at different time points after middle cerebral arte
Rett syndrome (RTT) is caused by loss-of-function mutations in the X-linked gene MECP2 coding for methyl CpG-binding protein 2 (MeCP2). This protein can act as transcriptional repressor and we showed in a previous study that glucocorticoid-inducible genes are up-regulated in a RTT mouse model and that these genes are direct MeCP2 targets. Here, we report that pharmacological intervention with the
Neural stem cells (NSCs) have attracted major research interest due to their potential use in cell replacement therapy. In patients, human cells are the preferred choice, one source of human NSCs being the brain of fetuses. The aims of the present study were to explore the long-term differentiation, mobility and viability of NSCs derived from the human fetal striatum in response to intracerebral i
BACKGROUND: Allogeneic stem cell transplantation (alloSCT) reduces relapse rates in acute leukemia, but outcome is hampered by toxicity. Population-based data avoid patient selection and may therefore substitute for lack of randomized trials. METHODS: We evaluated alloSCT rates within the Swedish Acute Leukemia Registry, including 3899 adult patients diagnosed from 1997 through 2006 with a coverag
PURPOSEAPR-246 (PRIMA-1MET) is a novel drug that restores transcriptional activity of unfolded wild-type or mutant p53. The main aims of this first-in-human trial were to determine maximum-tolerated dose (MTD), safety, dose-limiting toxicities (DLTs), and pharmacokinetics (PK) of APR-246. PATIENTS AND METHODSAPR-246 was administered as a 2-hour intravenous infusion once per day for 4 consecutive d
Breathlessness is a major cause of suffering and distress and little is known about the trajectory of breathlessness near death.
Patient-reported outcomes (PROs), such as symptoms and perceived health status, are essential in chronic obstructive pulmonary disease (COPD) for determining disease severity, impact on daily life, effect of treatment and recovery from exacerbations. This field has evolved rapidly and there are a plethora of instruments assessing different PROs. Here, we aim to provide an understanding of the conc
Background: A family history of melanoma is associated with an increased risk of melanoma and probably of other, discordant cancers. Limited data are available on familial mortality in melanoma. If fatal forms of melanoma were associated with fatal forms of melanoma or of some other cancers, only studies on familial mortality rather than on familial incidence might be able to detect them. Furtherm
