Hard turning offers a cost-effective alternative to traditional grinding, yet the tool wear progression limits the broader industrial adoption. During hard turning, the surface microstructure of AISI 52100 steel transforms into a nanocrystalline structure known as white layer, accompanied by significant surface residual stresses. With optimal cutting conditions, surfaces develop nanocrystalline mi
Objectives: Long-term, placebo-controlled studies of cholinesterase inhibitors (ChEIs) in Alzheimer’s disease (AD) are not permitted for ethical reasons. Therefore, the advancement of knowledge on longitudinal outcomes in different domains warrants well-designed naturalistic studies. The aim of this study was to explore the 3-year effectiveness of rivastigmine treatment. Methods: The Swedish Alzhe
The aim of the study was to investigate whether work-study conflict and study-work conflict predict perceived stress and well-being in full-time university students who work part-time, and whether perceived stress predicts well-being. The study was conducted with a quantitative cross-sectional design where data were collected through a web-based questionnaire where participants answered establishe
Rationale: Benzodiazepines, gabapentinoids, hypnotics, and opioids can depress respiration, alter sleep, and potentially affect outcomes in individuals treated with home mechanical ventilation (HMV) for obesity hypoventilation syndrome (OHS). Objectives: To analyze the association of benzodiazepines, gabapentinoids, hypnotics, and opioid use with hospitalization-free survival and mortality after s
Objectives: Various outcomes of cholinesterase inhibitor (ChEI) therapy have been observed in Alzheimer’s disease (AD). It is not clear whether the duration of treatment, type of ChEI, or dose affect mortality. We aimed to investigate the association between ChEI therapy and patient survival. Methods: The Swedish Alzheimer Treatment Study (SATS) is a prospective, observational, multicentre study t
Evidence suggests an influence of sex hormones on cutaneous melanoma risk, but epidemiologic findings are conflicting. We examined the associations between use of oral contraceptives (OCs) and menopausal hormone therapy (MHT) and melanoma risk in women participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). EPIC is a prospective cohort study initiated in 1992 in 1
Children's blood-lead concentration (B-Pb) is well studied, but little is known about cadmium (B-Cd) and mercury (B-Hg), in particular for central Europe. Such information is necessary for risk assessment and management. Therefore, we here describe and compare B-Pb, B-Cd and B-Hg in children in six European, and three non-European cities, and identify determinants of these exposures. About 50 scho
Prior study children from a DTaP efficacy trial were recruited at ages 5 and 15 years to randomized booster trials addressing immunogenicity and reactogenicity; 475 preschool children received mixed or separate injections of a reduced antigen vaccine (Tdap5, Sanofi Pasteur MSD) and an inactivated polio vaccine, and 230 adolescents received the same or another booster vaccine (Tdap1, SSI, Denmark).
Four-dimensional (4D) flow magnetic resonance imaging (MRI) enables quantification of kinetic energy (KE) in intraventricular blood flow. This provides a novel way to understand the cardiovascular physiology of the Fontan circulation. In this study, we aimed to quantify the KE in functional single ventricles. 4D flow MRI was acquired in eleven patients with Fontan circulation (median age 12 years,
Purpose: To determine the reproducibility of quantitative susceptibility mapping at multiple sites on clinical and preclinical scanners (1.5 T, 3 T, 7 T, and 9.4 T) from different vendors (Siemens, GE, Philips, and Bruker) for standardization of multicenter studies. Methods: Seven phantoms distributed from the core site, each containing 5 compartments with gadolinium solutions with fixed concentra
Previous studies have found that launch prices reflect the therapeutic gains of pharmaceuticals (for instance: Ekelund and Persson, 2003, on Sweden and Lu and Comanor, 1998, on the US). Furthermore, Howard et al (2015) found that purely pharmaceutical costs to “Medicare” at launch for new anticancer drugs increased annually, from 1995-2013, after controlling for health benefits and inflation. This
Background: BARD1 was originally identified as a BRCA1- interacting protein but has also been described in tumour-suppressive functions independent of BRCA1. Several studies have indicated that the BARD1 gene is a potential target for germline changes predisposing to breast and ovarian cancer. The C- terminal Cys557Ser change has previously been uncovered to associate with an increased risk of bre
Background: Reduced quadriceps strength is an early finding in subjects with knee osteoarthritis, but it is not clear whether it is a cause or a consequence of knee osteoarthritis. Objective: To determine whether reduced functional performance in the lower extremity predicts the incidence or progression of radiographic knee osteoarthritis. Design: Prospective, epidemiological, population based c
BACKGROUND: Persistent organochlorine pollutants (POPs) may interfere with reproductive function but direct evidence in humans is very limited. METHODS: Fertility was examined in four regions with contrasting blood levels of POPs. Pregnant women and their partners in Warsaw (Poland), Kharkiv (Ukraine) and Greenland were consecutively enrolled during antenatal visits. Swedish fishermen and their sp
OBJECTIVE - Consumption of a meal high in resistant starch or soluble fiber (P-glucan) decreases peak insulin and glucose concentrations and areas under the curve (AUCs). The objective was to determine whether the effects of soluble fiber and resistant starch on glycemic variables are additive. RESEARCH DESIGN AND METHODS - Ten normal-weight (43.5 years of age, BMI 22.0 kg/m(2)) and 10 overweight
BACKGROUND. This study was performed in women who had attended the clinic for contraceptive advice to determine whether a history of casual sex with a foreign male, previously unknown to them (SFM) in their home country (Sweden), constituted an increased risk for acquiring sexually transmitted diseases (STD) as compared to women without such an experience (COMP). METHODS. Of 996 women enrolled, an
BACKGROUND: A standardised suction technique has been used to sample plasma proteins in dermal interstitial fluid (IF) serially for 5 to 6 days from a suction-induced skin mini-erosion. Increased protein concentrations ascribed to inflammation have been shown from day 1 onward. In this study, we assessed the effect of two different extraction pressures on IF sample composition. METHODS: Total prot
BACKGROUND: To compare women with and without a history of recurrent symptoms suggestive of a urinary tract infection but a current negative urine culture regarding symptoms and signs of a genital infection, carriership of sexually transmitted agents and vaginal flora changes, sexual behavior and genital hygiene practice. SETTINGS: Contraceptive attendees at family planning and youth clinics. MATE
BACKGROUND AND PURPOSE: In a randomized study of hemiparetic stroke patients with a median age of 75 years, functional recovery was significantly better in those who received additional sensory stimulation (n = 38), including electrostimulation, than in control patients (n = 40) given the same physiotherapy and occupational therapy; group differences for balance, mobility, and activities of daily
