This article is open access.Recent case-control studies have shown an association between type 3 finger length pattern (longer ring finger than index finger) and knee osteoarthritis. This large cross-sectional study tests the hypothesis that the type 3 pattern is associated with total joint replacements due to osteoarthritis in a large population based study.Finger length ratios were assessed visually on 5170 hand photographs (2975 females, 2195 males, mean age 76). In this population-based multidisciplinary study of aging in Reykjavik, Iceland, the prevalence of osteoarthritis associated total knee replacements was 223(4.3%) and total hip replacements 316(6.1%). We then performed a binary logistic regression analysis for total knee replacements and total hip replacements, including finger length patterns, osteoarthritis at other sites and other variables with possible association to osteoarthritis such as age, BMI and bone mineral density of the spine.The prevalence of the type 3 pattern was 50% (43% in females, 58% in males). The regression analysis revealed an odds ratio for total knee replacements of 1.65 (1.24-2.2) p = 0.0007, in the type 3 finger pattern group, similar in both genders. This association was independent of the associations we have previously reported between total knee replacements and BMI and the presence of hand osteoarthritis. No association was seen between finger length patterns and total hip replacements.Finger length patterns read from digital photographs in this large study confirm previous radiographic observations with significant associations between the type 3 pattern and total knee replacements but not total hip replacements in both genders in this elderly group.NIH N01-AG-12100 NIA Intramural Research Program Hjartavernd (the Icelandic Heart Association) Althingi (the Icelandic Parliament) Icelandic Osteoarthritis Fund University of Iceland Research Fun

Sit, Eat, Drink, Talk, Laugh – Dining and Mixed Media

Sit, Eat, Drink, Talk, Laugh – Dining and Mixed Media, is an exploratory study of qualities in everyday life and challenges people to enjoy the qualities of mundanity. Seeking inspiration in ethnographic studies, field work was conducted in domestic settings, returning an extensive body of material to work from. The study challenges people to absorb the moment, reflect and enjoy, rather than pacing through a lifetime, with a constant focus on the future instead of the present. This work takes a starting point in food and dining as a social activity, where interactive sound and a reference to online social media is explored through two interventions. The results of these are discussed with central findings around food and dining in the area of sociology, the use of sound in ambient computing and on a higher level around the topic of temporality

Living or deceased donor kidney transplantation in children

Purpose of review Kidney transplantation is the preferred treatment modality for children with end-stage renal disease. In this review, we discuss the factors affecting the selection of the appropriate donor to ensure the best possible short and long-term outcomes. Recent findings Outcomes of pediatric renal transplantation from living donors are superior to those obtained from deceased donors. Despite this, the rate of living donor kidney transplantation has declined over the last decade. Living donation is considered to be safe but long-term outcomes, especially for parents who are often young donors, are not well understood. Living donation can also cause a financial impact to the donor and family. Barriers to living donation must be sought and defeated. Deceased donor organs are now the primary source of kidneys. How the risk of extended time on dialysis must be weighed against the improved outcomes that may accrue from better matching is controversial. Increasing the donor pool may be accomplished by reassessing sources that are currently avoided, such as donation after cardiac death and infant kidneys transplanted en bloc. Summary The pediatric nephrologist must balance waiting for the highest quality kidney against the need for the shortest possible waiting time

Association of BRCA2 K3326* With Small Cell Lung Cancer and Squamous Cell Cancer of the Skin.

However, a stop-gain mutation, K3326* (rs11571833), confers risk of lung cancer and cancers of the upper-aero-digestive tract but only a modest risk of breast or ovarian cancer. The Icelandic population provides an opportunity for comprehensive characterization of the cancer risk profiles of K3326* and HBOC mutations because a single mutation, BRCA2 999del5, is responsible for almost all BRCA2-related HBOC in the population. Genotype information on 43 641 cancer patients and 370 971 control subjects from Iceland, the Netherlands, and the United States was used to assess the cancer risk profiles of K3326* and BRCA2 999del5. BRCA2 expression was assessed using RNAseq data from blood (n = 2233), as well as 52 tissues reported in the GTEx database. The cancer risks associated with K3326* are fundamentally different from those associated with 999del5. We report for the first time an association between K3326* and small cell lung cancer (odds ratio [OR] = 2.06, 95% confidence interval [CI] = 1.35 to 3.16) and squamous cell carcinoma of the skin (OR = 1.69, 95% CI = 1.26 to 2.26). Individuals homozygous for K3326* reach old age and have children. Unlike BRCA2 999del5, the K3326* allele does not affect the level of BRCA2 transcripts, and the allele is expressed to the same extent as the wild-type allele. K3326* associates primarily with cancers that have strong environmental genotoxic risk factors. Expression of the K3326* allele suggests that a variant protein may be made that retains the DNA repair capabilities important to hormone-responsive tissues but may be less efficient in responding to genotoxic stress.deCODE genetics/Amgen American Cancer Society National Institutes of Health National Cancer Institut
