Do people with diabetes who need to talk want to talk?

Aim. To examine whether the people with diabetes who ask for psychological support are those who are experiencing clinically significant levels of psychological distress.
Method. In total 300 people with diabetes were asked to complete psychometrically validated questionnaires that assessed subjective need and objective psychological distress.
Results. High levels of psychological distress were reported: 25% of the sample reported depressive symptomatology, 41% reported clinically significant levels if anxiety and 51% reported a degree of binge eating behaviour. Participants also indicated a desire to talk to diabetes professionals about various problem areas in diabetes. Chi-square analysis demonstrated that those reporting psychological distress, especially depression, were most likely to indicate a desire to talk to somebody about living with diabetes.
Conclusions. Those who want to talk are those who need to talk. Future service development issues should acknowledge the needs and expressed wishes of service users.

Is screening for Factor V Leiden and Prothrombin G20210A Mutations in Renal Transplantation worthwhile? Results of a large single-center U.K. study

This single center study is the largest series of renal transplant recipients and donors screened for the commonest prothrombotic genotypes. A total of 562 transplant recipients and 457 kidney donors were genotyped for the factor V Leiden and prothrombin G20210A mutations. The prevalence of heterozygous factor V Leiden was 3.4% and 2.6% and prothrombin G20210A was 2.0% and 1.1% in recipients and donors, respectively, similar frequencies to that of the general U.K. population. The 30-day and 1-year graft survival rates in recipients with thrombophilic mutations were 93% and 93%, compared with 88% and 82% in patients without these mutations (log-rank P =0.34). Thrombophilia in recipients (odds ratio 0.55; confidence interval 0.06-2.29; P =0.56) or in donors (odds ratio 1.53; confidence interval 0.27-5.74; P =0.46) did not correlate with graft loss at 30 days after transplantation. In contrast to recent reports, this study did not demonstrate an association between thrombophilia and renal allograft loss, and routine screening is not recommended.

Exploration of the Kuiper Belt by High-Precision Photometric Stellar Occultations: First Results

We report here the first detection of hectometer-size objects by the method of serendipitous stellar occultation. This method consists of recording the diffraction shadow created when an object crosses the observer's line of sight and occults the disk of a background star. One of our detections is most consistent with an object between Saturn and Uranus. The two other diffraction patterns detected are caused by Kuiper Belt objects beyond 100 AU from the Sun and hence are the farthest known objects in the solar system. These detections show that the Kuiper Belt is much more extended than previously believed and that the outer part of the disk could be composed of smaller objects than the inner part. This gives critical clues to understanding the problem of the formation of the outer planets of the solar system.
