Conundrum of mechanical knee symptoms : Signifying feature of a meniscal tear?
Background: Mechanical knee symptoms are often considered important in the decision to perform knee arthroscopy on the suspicion of a meniscal tear. We investigated if presence of a meniscal tear at knee arthroscopy in adults is associated with presence of preoperative self-reported mechanical knee symptoms. Methods: We used data from Knee Arthroscopy Cohort Southern Denmark (KACS). KACS consists
Disappearing Investment-Cash Flow Sensitivities: Earnings Have Not Become a Worse Proxy for Cash Flow
According to a recent conjecture in the literature, earnings have become a poorer proxy for cash flow from operations over time. We find that since 1988, when cash flow statements started to be consistently reported in Compustat, the cash effectiveness of earnings has actually increased for a large sample of US manufacturing firms. This occurs despite the introduction of fair value accounting and According to a recent conjecture in the literature, earnings have become a poorer proxy for cash flow from operations over time.

Reappearing Investment-Cash Flow Sensitivities
According to previous research the investment-cash flow sensitivity has fallen over time to levels approaching zero in the 2000s, prompting some researchers to argue that the sensitivity cannot be a reasonable measure of financing constraints. We show that differences in sensitivities reappear if one sorts firm according to firms’ need for funding (investment rates) and the cost of external fundin
GABPA inhibits invasion/metastasis in papillary thyroid carcinoma by regulating DICER1 expression
The ETS family transcription factor GABPA is suggested as an oncogenic element, which is further supported by the recent reporting of it as the sole ETS member to activate the mutant TERT promoter in thyroid carcinomas (TC). However, it remains unclear how GABPA contributes to TC pathogenesis. The present study is designed to address this issue. TERT expression was significantly diminished in TERT
Infective endocarditis due to Streptococcus dysgalactiae : clinical presentation and microbiological features
Knowledge of infective endocarditis (IE) caused by Streptococcus dysgalactiae (SD) is limited. This study aimed to identify the clinical and microbiological features of SD-caused IE and to investigate any possible synergy between penicillin and gentamicin on SD isolates. Cases of IE 2008–2016 due to SD reported to the Swedish Registry of Infective Endocarditis (SRIE) were identified. Isolates were
EANM practical guidance on uncertainty analysis for molecular radiotherapy absorbed dose calculations
A framework is proposed for modelling the uncertainty in the measurement processes constituting the dosimetry chain that are involved in internal absorbed dose calculations. The starting point is the basic model for absorbed dose in a site of interest as the product of the cumulated activity and a dose factor. In turn, the cumulated activity is given by the area under a time–activity curve derived
Investigating the Onset of Strain Localization Within Anisotropic Shale Using Digital Volume Correlation of Time-Resolved X-Ray Microtomography Images
Digital volume correlation analysis of time-resolved X-ray microtomography scans acquired during in situ triaxial compression of Green River shale cores provided time series of 3-D incremental strain fields that elucidated evolving deformation processes by quantifying microscopic strain localization. With these data, we investigated the impact of mechanical anisotropy on microscopic strain localiz
A virtual promise of happiness : kinship on the websites of Danish fertility clinics and sperm banks
Each month thousands of people travel across national borders to access assisted reproductive treatments across Europe. The possibility to purchase fertility treatments in a similar way to other products and services has led not only to a clearly defined market place and customer, but has also contributed to scholarly work on critical studies of kinship. To date, however, there has been little res

Learning to teach STEM disciplines in higher education : a critical review of the literature
Enrolments in STEM disciplines at universities are increasing globally, attributed to the greater life opportunities open to students as a result of a STEM education. But while institutional access to STEM programmes is widening, the retention and success of STEM undergraduate students remains a challenge. Pedagogies that support student success are well known; what we know less about is how unive
The Quest for Significance : Attitude Adaption to a Radical Group Following Social Exclusion
It is a human fundamental to desire to be valued, loved and respected - to be significant. Social exclusion induce significance loss which elicits a 'quest for significance' - the search for opportunities to re-gain significance. The present article establishes this relation in a laboratory experiment (N = 71, mean age = 28, SD = 10.42, 65% women, 35% men), showing that socially excluded individua
Participatory parity in schooling and moves towards ordinariness : a comparison of refugee education policy and practice in England and Sweden
Within the current global refugee crisis this paper emphasises the fundamental role of education in facilitating the integration of young new arrivals. It argues that a humanitarian problem of such scale requires a commensurate humanitarian response in the form of socially-just educational policies and practices in resettlement contexts within Europe. Utilising the theoretical concepts, ‘participa
Impact of family history of cancer on risk and mortality of second cancers in patients with prostate cancer
Background: Survival rates are increasing in patients with prostate cancer, and second primary cancers (SPCs) are becoming more common in these patients. However, the etiology and clinical consequences of SPCs are not well-known. We define the impact of family history on SPC and causes of mortality in these patients. Patients and methods: A nation-wide cohort study based on the Swedish Family-Canc
Guadalcanal 1942: alla bröderna dog i vågorna

Prevalence and Clinical Relevance of Extracardiac Findings in Cardiovascular Magnetic Resonance Imaging
Purpose: To assess the prevalence of extracardiac findings (ECF) during cardiovascular magnetic resonance (CMR) examinations and their downstream effect on clinical management. Materials and Methods: We retrospectively identified 500 consecutive patients. Trans-axial balanced steady-state free precession nongated images acquired from the upper thorax to the upper abdomen were evaluated independent
Early oral contraceptive use as a prognostic factor in breast cancer
The survival of 193 premenopausal breast cancer patients was investigated in relation to their history of early use of oral contraceptives. The women were born in 1939 or later and diagnosed in the southern health care region of Sweden. Women, who had started their oral contraceptive use (OC-use) before 20 years of age had a significantly lower survival rate as compared with those who had never us

Optimization of soft X-ray phase-contrast tomography using a laser wakefield accelerator
X-ray phase-contrast imaging allows for non-invasive analysis in low-absorbing materials, such as soft tissue. Its application in medical or materials science has yet to be realized on a wider scale due to the requirements on the X-ray source, demanding high flux and small source size. Laser wakefield accelerators generate betatron X-rays fulfilling these criteria and can be suitable sources for p
