Preterm birth and unintentional injuries: risks to children, adolescents and young adults show no consistent pattern.

AIM: Preterm birth is associated with a number of physical and mental health issues. The aim of this study was to find out if there was also any association between individuals born preterm in Sweden between 1984 and 2006 and the risk of unintentional injuries during childhood, adolescence and young adulthood METHODS: The study followed 2,297,134 individuals, including 5.9% born preterm, from 1985

A 3.6mW, 90nm CMOS Gated-Vernier Time-to-Digital Converter with an Equivalent Resolution of 3.2ps

Two gated ring oscillators (GROs) act as the delay lines in an improved Vernier time-to-digital converter (TDC), where the already small quantization noise of the standard Vernier TDC is further first-order shaped by the GRO operation. The TDC has been implemented in a 90nm CMOS process and consumes 3mA from 1.2V when operating at 25MHz. The native Vernier resolution of the TDC is 5.8ps, while the

Hypothermia after Cardiac Arrest: Lessons Learned from National Registries.

Abstract Therapeutic hypothermia has been shown to improve outcome in comatose survivors after cardiac arrest of cardiac origin. After the clinical implementation of this novel treatment, several international web-based registries were opened to facilitate the prospective collection of patient treatment data. The aim was to evaluate the actual use of hypothermia in clinical practice, safety aspect

Determination of age-specific and sex-specific familial risks for the different manifestations of venous thromboembolism: A nationwide family study in Sweden.

This nationwide study aimed to determine whether differences exist in age-specific and sex-specific familial risks for pulmonary embolism (PE), venous thrombosis of the lower limbs (VT) and other forms of venous thromboembolism (OVTE) among offspring, siblings and spouses of affected individuals. The Swedish Multi-Generation Register was linked to the Hospital Discharge Register data for the perio

Anterior Segment Abnormalities and Angle-Closure Glaucoma in a Family with a Mutation in the BEST1 Gene and Best Vitelliform Macular Dystrophy.

Purpose: To present the clinical and electrophysiological findings in four members of a family with Best vitelliform macular dystrophy (BVMD) and angle-closure glaucoma (ACG). Methods: Four members of a family with BVMD were examined clinically, including visual acuity, slit-lamp examination, biomicroscopy, Goldmann applanation tonometry and gonioscopy. Measurements of the anterior chamber depth a

On Optimal Filter Designs for Fundamental Frequency Estimation

Recently, we proposed using Capon's minimum variance principle to find the fundamental frequency of a periodic waveform. The resulting estimator is formed such that it maximizes the output power of a bank of filters. We present an alternative optimal single filter design and then proceed to quantify the similarities and differences between the estimators using asymptotic analysis and Monte Carlo s

Rationalization in meat cutting - Consequences on physical workload.

Meat cutting is associated with several ergonomic risk factors and a high risk of musculoskeletal disorders. The development of new production systems points to an increased degree of mechanization; instead of subdividing split carcasses of pigs with a knife, the halves are trisected by an electrical saw into 'sixth-parts', resulting in shorter work cycles for the workers. Recently, machine-direct

Antenna Analysis and Design Using Stored Energies and Physical Limitations

Popular Abstract in Swedish Antenner finns idag nästan överallt: i mobiltelefoner, bärbara datorer, surfplattor, kameror, skrivare, klockor och armbandsur, o.s.v. De används för att överföra information trådlöst mellan enheter med hjälp av elektromagnetiska vågor (som har egenskapen att utbreda sig, ungefär på samma sätt som vågorna rör sig på en vattenyta när man kastar en liten sten). Ju mer avA method to estimate Q and QZ' of antennas from single-frequency current distributions is described. This single-frequency method and the concepts of physical bounds on antenna parameters and optimum current distributions are applied to different analysis and design situations of two-dimensional and three-dimensional radiating structures (i.e., antennas). The situations considered are: antenna opt

Effects of rose hip intake on risk markers of type 2 diabetes and cardiovascular disease: a randomized, double-blind, cross-over investigation in obese persons.

BACKGROUND/OBJECTIVES:In studies performed in mice, rose hip powder has been shown to both prevent and reverse high-fat diet-induced obesity and glucose intolerance as well as reduce plasma levels of cholesterol. The aim of this study was to investigate whether daily intake of rose hip powder over 6 weeks exerts beneficial metabolic effects in obese individuals.SUBJECTS/METHODS:A total of 31 obese

Collagen antibody induced arthritis

Rheumatoid arthritis (RA) is a polygenic and multifactorial disease. Many complex immunological and genetic interactions are involved in the final out come of the clinical disease. To understand the various disease pathways operating during the disease course, we need many different animal models. Collagen induced arthritis (CIA) is one of the widely used animal models sharing many pathological an
