Filtyp
Endwall film cooling is a significant cooling method to protect the endwall region and the junction region of endwall and a turbine vane, where usually a relatively high temperature load exists. This work aims to find the optimized arrangement of film cooling holes on the endwall and improve the film cooling in some difficult regions on the endwall, such as pressure side-endwall junction region. S
When doped into solid state transparent crystals, rare-earth ions can have optically excited states with milliseconds coherence time and up to six hours coherence time for hyperfine levels after being cooled down to liquid helium temperature. This long coherence property makes them unique as solid state material and attractive for quantum information applications.The rare-earth ions have narrow ho
The burden of depression and anxiety disorders is greater in women, and female sex hormones have been shown to affect mood. Psychological side effects of hormonal contraception (HC) are also a common complaint in the clinic, but few previous studies have investigated this subject. We therefore wanted to investigate whether use of HC was associated with adverse psychological health outcomes, and wh
Objective To investigate whether oral fluoroquinolone use is associated with an increased risk of aortic aneurysm or dissection. Design Nationwide historical cohort study using linked register data on patient characteristics, filled prescriptions, and cases of aortic aneurysm or dissection. Setting Sweden, July 2006 to December 2013. Participants 360 088 treatment episodes of fluoroquinolone use (
Objectives: The aim was to investigate if there is an interaction between sitting time and leisure time physical activity on blood pressure and if there are age differences and sex differences in this respect. Methods: Linear regression analysis on cross-sectional data was performed in more than 45 000 men and women from two Swedish cohort studies, EpiHealth (45-75 years) and LifeGene (18-45 years
Glycans are biologically important structures synthesised by glycosyltransferase (GT) enzymes. Disruptive genetic null variants in GT genes can lead to serious illness but benign phenotypes are also seen, including antigenic differences on the red blood cell (RBC) surface, giving rise to blood groups. To characterise known and potential carbohydrate blood group antigens without a known underlying
Purpose: To explore and compare cancer patients' perceptions on the quality of nursing care in four European countries. Methods: Data were collected in Cyprus, Finland, Greece and Sweden. The sample comprised 596 hospitalized cancer patients. The quality of nursing care was measured using the “Oncology Patients' Perceptions of the Quality of Nursing Care Scale” (OPPQNCS). Patient characteristics w
Objective: Previous studies have shown that both sleep duration and insomnia have an impact on obesity and central obesity. However, studies of the joint effects of these sleep disorders are still sparse. Methods: The present study utilized data from the Swedish EpiHealth cohort study. Participants (45–78 y) were asked to fill out an internet-based questionnaire. Body mass index (BMI) and central
Recent studies have raised concern that macrolide antibiotics may be associated with an increased long-term risk of cardiovascular death. We examined the 1-year risk associated with treatment with clarithromycin (n = 187,887) or roxithromycin (n = 698,899) compared with penicillin V (n = 3,473,081) matched 1:4 on propensity score, in a nationwide, registry-based cohort study in Danish outpatients,
To be relevant for public health, a context (e.g., neighborhood, school, hospital) should influence or affect the health status of the individuals included in it. The greater the influence of the shared context, the higher the correlation of subject outcomes within that context is likely to be. This intra-context or intra-class correlation is of substantive interest and has been used to quantify t
During the last decade, policymakers, learned societies, non-governmental organisations (NGOs) and some national alliances of all three of these groups have advocated, developed and implemented systematic approaches to fragility fracture care and prevention in a growing number of countries. This chapter reviews the impact of Orthogeriatric Services (OGS) and Fracture Liaison Services (FLS) on deli
Background: Several factors have been reported that influence the probability of a germline CDKN2A mutation in a melanoma family. Our goal was to create a scoring system to estimate this probability, based on a set of clinical features present in the patient and his or her family. Methods: Five clinical features and their association with CDKN2A mutations were investigated in a training cohort of
Background: Kidney transplantation is considered a superior treatment for end-stage renal disease compared with dialysis although little is known about the wider effects, especially on labor market outcomes. The objective is to estimate the treatment effect of kidney transplantation compared with dialysis on labor market outcomes, controlling for the nonrandom selection into treatment. Methods: Th
Objectives We examined whether daily physical activity (PA) during compulsory school encourages children to be more physically active during the intervention and 4 years after termination of the programme. Methods This prospective controlled intervention study followed the same 124 children (81 children in an intervention group and 43 controls) aged 7.7±0.6 (mean±SD) during a 7-year PA interventio
Background: Little is known about accuracy of common risk prediction scores in elderly patients suffering from hip fractures. The objective of this study was to investigate accuracy of the Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) score, Portsmouth-POSSUM (P-POSSUM) score and the Nottingham Hip Fracture Score (NHFS) for prediction of mortali
Objective: To investigate the prevalence of voice disorders in the general population. Study design: Analysis of data from the Stockholm Public Health Cohort. Methods: A public health survey was distributed to an open cohort of 114,538 adults >18 years of age in the area of Stockholm County, Sweden. The survey included one question about voice problems, estimating the extent of occurrence of voice
Fragility fractures are increasingly recognized as a complication of both type 1 and type 2 diabetes, with fracture risk that increases with disease duration and poor glycemic control. Yet the identification and management of fracture risk in these patients remains challenging. This review explores the clinical characteristics of bone fragility in adults with diabetes and highlights recent studies
Many neurological diseases are followed by a disturbance of nutritional intake to some extent and thus constitute the most common indication for nutritional support and enteral access. Several studies have shown that malnutrition is a common condition, with as many as 40% of admitted patients being identified as undernourished and 78% of these further found to be deteriorated in their nutritional
Background: In Western settings, community-acquired pneumonia (CAP) due to Gram-negative bacilli (GNB) is relatively rare. Previous studies from Asia, however, indicate a higher prevalence of GNB in CAP, but data, particularly from Southeast Asia, are limited. Methods: This is a prospective observational study of 1451 patients ≥15 y of age with CAP from two hospitals in Cambodia between 2007 and 2
