Abstract

Non-invasive prenatal testing (NIPT) demonstrated a small chance for a false negative result. Since the "fetal" DNA in maternal blood originates from the cytotrophoblast of chorionic villi (CV), some false negative results will have a biological origin. Based on our experience with cytogenetic studies of CV, we tried to estimate this risk. 5967 CV samples of pregnancies at high risk for common aneuplodies were cytogenetically investigated in our centre between January 2000 and December 2011. All cases of fetal trisomy 13, 18 and 21 were retrospectively studied for the presence of a normal karyotype or mosaicism < 30% in short-term cultured (STC-) villi. 404 cases of trisomies 13, 18 and 21 were found amongst 5967 samples (6,8%). Of these 404 cases, 14 (3,7%) had a normal or low mosaic karyotype in STC-villi and therefore would potentially be missed with NIPT. It involved 2% (5/242) of all trisomy 21 cases and 7.3% (9/123) of all trisomy 18 cases. In 1:426 (14/5967) NIPT samples of patients at high risk for common aneuploidies, a trisomy 18 or 21 will potentially be missed due to the biological phenomenon of absence of the chromosome aberration in the cytotrophoblast.

Abstract

Consumer Information Processing (CIP) handlar om hur vi som konsumenter tar till ossoch påverkas av den information som ständigt omger oss vid en beslutssituation. Ämnethar länge varit i fokus för forskning inom marknadsföring då detta naturligtvisintresserar företagen i hög grad. Tidigare forskning hävdar att när vi som konsumentertar till oss av de intryck som omger oss, bearbetas dessa intryck tillsammans med dekunskaper vi har sedan tidigare (bottom-up processing och top-down processing).Studier har visat att information som tilldelas oss kan ha direkt påverkan på våra sinnenoch hur vi upplever en produkt.Denna studie undersökte hur olika typer av tilläggsinformation påverkade konsumentersupplevda smak av vin. Tolv testpersoner studerades i ett experiment bestående av tresteg där olika betyg presenterades på de viner testpersonerna bedömde. Resultatet avstudien visade att kvinnor i högre grad påverkas av negativ tilläggsinformation medanmän i högre grad påverkas av positiv tilläggsinformation. The subject of Consumer Information Processing (CIP) addresses how we as consumersgets affected by the present amount of information that constantly surrounds us in adecision situation. This subject has long been in the center of focus for research withinthe field of marketing because the high level of interest from a company viewpoint.Earlier research claims that a process occours when surrounding information reaches theconsumer, involving both the surrounding information but also the consumer´s ownprevious knowledge and experiences (bottom-up and top-down processing). Studieshave shown that added information can actually have direct affect on how our senseswork and therefore also affect how we perceive a product.This paper studied the affect of different types of added information on consumer'sperceived taste of wine. A total of twelve participants were studied in an experimentconstisting of three steps. Different ratings of the wines were presented to theparticipants prior to judging. The result of the study showed that women were affectedby negativ type of added information at a higher rate, whilst men were more affected bypositive added information.

Abstract

Background: Survival after a diagnosis of breast cancer varies considerably between patients, and some of this variation may be because of germline genetic variation. We aimed to identify genetic markers associated with breast cancer-specific survival. Methods: We conducted a large meta-analysis of studies in populations of European ancestry, including 37 954 patients with 2900 deaths from breast cancer. Each study had been genotyped for between 200 000 and 900 000 single nucleotide polymorphisms (SNPs) across the genome; genotypes for nine million common variants were imputed using a common reference panel from the 1000 Genomes Project. We also carried out subtype-specific analyses based on 6881 estrogen receptor (ER)-negative patients (920 events) and 23 059 ER-positive patients (1333 events). All statistical tests were two-sided. Results: We identified one new locus (rs2059614 at 11q24.2) associated with survival in ER-negative breast cancer cases (hazard ratio [HR] = 1.95, 95% confidence interval [CI] = 1.55 to 2.47, P = 1.91 x 10(-8)). Genotyping a subset of 2113 case patients, of which 300 were ER negative, provided supporting evidence for the quality of the imputation. The association in this set of case patients was stronger for the observed genotypes than for the imputed genotypes. A second locus (rs148760487 at 2q24.2) was associated at genome-wide statistical significance in initial analyses; the association was similar in ER-positive and ER-negative case patients. Here the results of genotyping suggested that the finding was less robust. Conclusions: This is currently the largest study investigating genetic variation associated with breast cancer survival. Our results have potential clinical implications, as they confirm that germline genotype can provide prognostic information in addition to standard tumor prognostic factors.

Abstract

Background Achilles tendon disorders, like Achilles tendinopathy, are very common among athletes. In the general population, however, knowledge about the incidence of Achilles tendinopathy is lacking. Design Cross-sectional study. Methods In a cohort of 57.725 persons registered in primary care, the number of patients visiting the general practitioner (GP) with diagnosis of mid-portion Achilles tendon problems was counted using computerised registration networks of GPs in 2009. Subsequently, the authors assessed associations of these rates with demographic characteristics. Results The incidence rate of Achilles tendinopathy is 1.85 per 1,000 Dutch GP registered patients. In the adult population (21-60 years), the incidence rate is 2.35 per 1,000. In 35% of the cases, a relationship with sports activity was recorded. Conclusion This is the first report on incidence rates of mid-portion Achilles tendinopathy in general practice. With an incidence of 1.85 per 1,000 registered persons, Achilles tendinopathy is frequently seen by GPs. The actual incidence might even be higher due to study limitations. More research on the frequency of this injury is required.
