The right to withdraw one's consent after having agreed to participate in research is a fundamental principle in contemporary research ethics. However, it has been questioned whether this right should apply to research conducted on donated biological samples, including stem cells and tissues from which stem cells can be derived. In this article we present some of the concerns that have been expres
The optimal FiO2 for newborn resuscitation is still not settled. We hypothesized that short-lasting oxygen ventilation after intrauterine asphyxia would not cause arterial or cerebral hyperoxia, and therefore be innocuous. The umbilical cord of fetal sheep was clamped and 10 min later, after delivery, ventilation with air (n=7) or with 100% oxygen for 3 (n=6) or 30 min (n=5), followed by air, was
Osteoarthritis (OA) involves all the structures of the joint. How the disease is initiated and what factors trigger the disease process remain unclear, although the mechanical environment seems to have a role. Our understanding of the biology of the disease has been hampered by the lack of access to tissue samples from patients with early stage disease, because clinically recognizable symptoms app
The aim was to psychometrically evaluate the activities of daily living (ADL)-staircase in various age groups. This age stratified, cross-sectional study comprised 826 individuals aged 18-102 years. The factor structure was assessed by means of hierarchical cluster analyses, plots and analyses of nonclassifiable responses. Reliability was assessed in terms of internal consistency. In general, the
We examined the importance of injury for the epidermal innate immune response in human skin wounds. We found that injury, independent of infiltrating inflammatory cells, generated prominent chemotactic activity toward neutrophils in injured skin because of IL-8 production. Furthermore, injury was a major inducer of the expression of antimicrobial (poly)peptides (AMPs) in skin wounds. In human skin
A new 13 items rating scale assessing self-reported impairments in persons with late effects of polio (SIPP) has been developed. SIPP has been Rasch analyzed and shown good construct validity and internal consistency. To establish its clinical utility, further evaluation of its psychometric properties is needed.
An NDVI dataset covering Fennoscandia and the Kola peninsula was created for vegetation and climate studies, using Moderate Resolution Imaging Spectroradiometer 16-day maximum value composite data from 2000 to 2005. To create the dataset, ( 1) the influence of the polar night and snow on the NDVI values was removed by replacing NDVI values in winter with a pixel- specific NDVI value representing t
BACKGROUND:: Early-term birth (gestational age, 37-38 weeks) has been associated with increased infant mortality relative to later-term birth, but mortality beyond infancy has not been studied. We examined the association between early-term birth and mortality through young adulthood. METHODS:: We conducted a national cohort study of 679,981 singleton births in Sweden in 1973-1979, followed up for
OBJECTIVE: to investigate how women who attended group antenatal care experienced the information they received, compared with women who attended traditional antenatal care, and their satisfaction with the form of care. The aim was also to determine the effect of group antenatal care on women's social networks compared with traditional antenatal care. DESIGN AND SETTING: a pilot study with an inte
AIM: This retrospective study evaluated long-term effects of percutaneous transluminal renal angioplasty (PTRA) in atherosclerotic renal artery stenosis (ARAS), and predictors of benefit on blood pressure (BP). METHODS: During 1997-2003, 234 patients (age 69+/-11 years, 138 [59%] males) underwent PTRA for ARAS at Malmö Vascular Centre. Cure was defined as diastolic (D)BP<90 mmHg and systolic (S)BP
OBJECTIVE: To evaluate feasibility and morbidity of robot assisted laparoscopic radical hysterectomy. METHODS: From December 2005 to September 2008 robot assisted laparoscopic radical hysterectomy and pelvic lymphadenectomy was performed on 80 women. Using a prospective protocol, and an active investigation policy for defined adverse events, perioperative, short and long term data were obtained. R
Palliative chemotherapy treatment (PCT) offered late in the cancer disease trajectory may be problematic. It is not easy to accurately calculate whether the potential benefits will outweigh the side-effects. This study investigates whether routine use of the Performance Status in Palliative Chemotherapy questionnaire (PSPC) affects the proportions of patients receiving PCT during the last month of
BACKGROUND: Practically all data on familial risk in ovarian and other cancers are based on incident cancer, whereas familiality in cancer mortality is largely unknown. If fatal forms of cancer are a highly familial subtype, then familial risk for mortality may exceed that of incidence, which is relevant for clinical decision making and counseling. METHODS: Ovarian cancer patients in the nationwid
Background:Podocalyxin-like 1 (PODXL) is a cell-adhesion glycoprotein and stem cell marker that has been associated with an aggressive tumour phenotype and poor prognosis in several forms of cancer. In this study, we investigated the prognostic impact of PODXL expression in colorectal cancer (CRC).Methods:Using tissue microarrays and immunohistochemistry, PODXL expression was evaluated in 536 inci
A 32-year-old man with a residual spastic quadriparesis from a traumatic C5-C6 fracture experienced a severe thunderclap headache. The medical history revealed an episode of autonomic dysreflexia (AD) due to neurogenic bladder/urinary tract infection (UTI). Blood pressure monitoring at admission revealed hypertension; blood pressure reaching 160/100 mmHg (average blood pressure in these patients a
