Lower extremity function in patients with early rheumatoid arthritis during the first five years, and relation to other disease parameters

Objective: The objective of this study was to investigate lower extremity function in early rheumatoid arthritis (RA) and assess its relation to other disease parameters. Methods: An inception cohort (recruited in 1995–2005) of patients with early RA was followed according to a structured protocol. Lower extremity function was investigated at inclusion and after 1, 2, and 5 years using the Index o

Mission, Money and Power

The term mission in its modern meaning was coined during the expansion of western Christianity which was in many ways entangled with colonialism. The western missionary movement’s modus operandi was adopted by missions from other backgrounds as well, when economic growth and growth of revivalist Christianity have coincided. When the outcome is new churches in economically underprivileged areas, th

Fracture incidence after tibial shaft fractures. A 30-year follow-up study

Based on all patients with tibial shaft fracture (n = 767) treated in the department of orthopedics in Malmö from 1955 to 1963, a retrospective cohort study was performed in 1990. Two hundred sixty-nine of the patients were still living in Malmö or had died in the city. Since all roentgenograms were available, all other fractures that this group of patients had sustained up to 1990 were included.

Comparison of Voxel-Wise and Histogram Analyses of Glioma ADC Maps for Prediction of Early Therapeutic Change

Noninvasive imaging methods are sought to objectively predict early response to therapy for high-grade glioma tumors. Quantitative metrics derived from diffusion-weighted imaging, such as apparent diffusion coefficient (ADC), have previously shown promise when used in combination with voxel-based analysis reflecting regional changes. The functional diffusion mapping (fDM) metric is hypothesized to

Acute spinal trauma

Injuries to the spinal column and spinal cord are a major cause of disability, affecting predominately young, healthy individuals. The majority of the spinal injuries (60%) affect young healthy males between 15 and 35 years of age, with important socioeconomic consequences, and the costs of lifetime care and rehabilitation are extremely high. As the longevity of the general population increases, t

Radiology in cutaneous sinuses and fistulae

In patients with cutaneous openings, sinograph and fistulography are usually performed. Fistulae in the head/neck region and perineum are seldom life-threatening while enterocutaneous fistulae involving the small bowel can be a serious threat due to loss of fluid. Radiology contributes to the preoperative examination of these patients. Fistulography outlines communications to the gastrointestinal

Acoustic Enrichment of Extracellular Vesicles from Biological Fluids

Extracellular vesicles (EVs) have emerged as a rich source of biomarkers providing diagnostic and prognostic information in diseases such as cancer. Large-scale investigations into the contents of EVs in clinical cohorts are warranted, but a major obstacle is the lack of a rapid, reproducible, efficient, and low-cost methodology to enrich EVs. Here, we demonstrate the applicability of an automated

Uptake, depuration and sublethal effects of the neonicotinoid, imidacloprid, exposure in Sydney rock oysters

The broad utilisation of imidacloprid (IMI)in agriculture poses an increasing risk to aquatic organisms. However, the potential impacts on commercially important shellfish and chemical residues after exposure, are yet to be assessed. We investigated the levels of IMI in Sydney rock oyster (SRO)tissue during a three-day uptake and four-day depuration cycle using liquid chromatography-mass spectrome

The significance of bicuspid aortic valve after surgery for acute type A aortic dissection

OBJECTIVE: Decision-making concerning the extent of the repair of acute type A aortic dissection (ATAAD) includes functional and anatomical assessment of the aortic valve. We hypothesized that bicuspid aortic valve (BAV) does not impact outcome after surgery for ATAAD. We therefore evaluated the outcome after ATAAD surgery in relation to the presence of BAV, acute aortic regurgitation (AR), and su

Is there a weekend effect in surgery for type A dissection? - Results from the NORCAAD database

BACKGROUND: Aortic dissection type A requires immediate surgery. In general surgery populations, patients operated during weekends have higher mortality rates compared to patients operated on weekdays. The weekend effect in aortic dissection type A has not been studied in detail.METHODS: The Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) registry includes patients (N=1,159) who und

Long-term outcome after coronary endarterectomy adjunct to coronary artery bypass grafting

OBJECTIVES: Coronary endarterectomy (CE) in coronary artery bypass grafting (CABG) is occasionally required to achieve revascularization in diffusely diseased vessels. Its beneficial effect has been questioned because of an increased risk of perioperative mortality and morbidity; however, its influence on the long-term outcome remains uncertain. The purpose of the study was to evaluate the impact

Preoperative dual antiplatelet therapy increases bleeding and transfusions but not mortality in acute aortic dissection type A repair

OBJECTIVES: Acute aortic dissection type A is a life-threatening condition, warranting immediate surgery. Presentation with sudden chest pain confers a risk of misdiagnosis as acute coronary syndrome resulting in subsequent potent antiplatelet treatment. We investigated the impact of dual antiplatelet therapy (DAPT) on bleeding and mortality using the Nordic Consortium for Acute Type A Aortic Diss

Difference in Outcome Following Surgery for Native Aortic and Mitral Valve Infective Endocarditis

BACKGROUND: We investigated differences in clinical presentation, microbiology, and short- and long-term results according to the affected valve in patients who underwent surgery for left-sided native valve infective endocarditis (IE).METHODS: This was a single-center retrospective study of 117 patients with isolated mitral valve IE (group M) and 140 patients with isolated aortic valve IE (group A

Hospital volumes and later year of operation correlates with better outcomes in acute Type A aortic dissection

OBJECTIVES: Acute Type A aortic dissection remains a life-threatening disease, but there are indications that its surgical mortality is decreasing. The aim of this report was to study how surgical mortality has changed and what influences those changes.METHODS: Nordic Consortium for Acute Type A Aortic Dissection is a retrospective database comprising 1159 patients (mean age 61.6 ± 12.2 years, 68%

Bone mineral loss after lower extremity trauma. 62 cases followed for 15-38 years

62 former patients, who had been treated at our department for tibial shaft fracture (n 38) or knee ligament injury (n 24) 15-38 years earlier, were re-evaluated for post-traumatic osteopenia. 62 age- and sex-matched subjects without fracture served as controls. By means of a Lunar DEXA apparatus we measured the bone mineral density (BMD) in the total body, the hips and special regions of interest

Correlation between estradiol-17 beta and progesterone cytosol receptor concentration, histologic differentiation and 3H-thymidine incorporation in endometrial carcinoma

Women treated with estrogen exhibit a higher risk of developing endometrial cancer. steroid hormones exert their effects on target tissue through specific cytosol receptor protein. Knowledge of this steroid receptor concentration in endometrial carcinoma might facilitate the treatment of recurrences. We have compared the concentrations of endometrial estrogen and progesterone cytosol receptors wit

HER-2/neu amplification predicts poor survival in node-positive breast cancer

HER-2/neu protooncogene amplification and protein expression were analyzed with slot blot and Western blot techniques, respectively, in more than 300 invasive primary breast tumors of all stages. Amplification (2- greater than 30 copies) was found in 17% of these tumors and high expression was seen in 19%. There was a striking coincidence between gene amplification and high expression. Tumors asso

The one-third rule for PI controller tuning

Despite academic advances in PID controller design and development of automatic tuning procedures, there are still many PID controllers that are badly tuned, or not even tuned at all, in process industry. There are several reasons for this, but one major reason is that it is considered too time consuming to use current PID controller tuning methods. This paper presents a new tuning method that is
