- The Swedish Defence Research Agency (FOI) has developed a concept demonstrator called the Information Fusion Demonstrator 2003 (IFD03) for demonstrating information fusion methodology suitable for a future Network Based Defense (NBD) C4ISR system. The focus of the demonstrator is on real-time tactical intelligence processing at the division level in a ground warfare scenario. The demonstrator integrates novel force aggregation, particle filtering, and sensor allocation methods to create, dynamically update, and maintain components of a tactical situation picture. This is achieved by fusing physically modelled and numerically simulated sensor reports from several different sensor types with realistic a priori information sampled from both a high-resolution terrain model and an enemy organizational and behavioral model. This represents a key step toward the goal of creating in real time a dynamic, high fidelity representation of a moving battalion-sized organization, based on sensor data as well as a priori intelligence and terrain information, employing fusion, tracking, aggregation, and resource allocation methods all built on well-founded theories of uncertainty. The motives behind this project, the fusion methods developed for the system, as well as its scenario model and simulator architecture are described. The main services of the demonstrator are discussed and early experience from using the system is shared.

- BACKGROUND: End-stage renal disease is associated with a high risk of cardiovascular events. It is unknown, however, whether mild-to-moderate kidney dysfunction is causally related to coronary heart disease (CHD) and stroke.METHODS: Observational analyses were conducted using individual-level data from 4 population data sources (Emerging Risk Factors Collaboration, EPIC-CVD [European Prospective Investigation into Cancer and Nutrition-Cardiovascular Disease Study], Million Veteran Program, and UK Biobank), comprising 648 135 participants with no history of cardiovascular disease or diabetes at baseline, yielding 42 858 and 15 693 incident CHD and stroke events, respectively, during 6.8 million person-years of follow-up. Using a genetic risk score of 218 variants for estimated glomerular filtration rate (eGFR), we conducted Mendelian randomization analyses involving 413 718 participants (25 917 CHD and 8622 strokes) in EPIC-CVD, Million Veteran Program, and UK Biobank.RESULTS: There were U-shaped observational associations of creatinine-based eGFR with CHD and stroke, with higher risk in participants with eGFR values <60 or >105 mL·min-1·1.73 m-2, compared with those with eGFR between 60 and 105 mL·min-1·1.73 m-2. Mendelian randomization analyses for CHD showed an association among participants with eGFR <60 mL·min-1·1.73 m-2, with a 14% (95% CI, 3%-27%) higher CHD risk per 5 mL·min-1·1.73 m-2 lower genetically predicted eGFR, but not for those with eGFR >105 mL·min-1·1.73 m-2. Results were not materially different after adjustment for factors associated with the eGFR genetic risk score, such as lipoprotein(a), triglycerides, hemoglobin A1c, and blood pressure. Mendelian randomization results for stroke were nonsignificant but broadly similar to those for CHD.CONCLUSIONS: In people without manifest cardiovascular disease or diabetes, mild-to-moderate kidney dysfunction is causally related to risk of CHD, highlighting the potential value of preventive approaches that preserve and modulate kidney function.

- The aim of the present study was to investigate the development of psychotherapists' professional self during training and the first few years after it. Constant comparison analysis was conducted on interviews with former students (N = 18) at a training institute for psychoanalytic psychotherapy. The resulting core category osearching for recognitiono indicated that participants' ambition during the studied time period was to reach high status by becoming psychotherapists. During training, this was expressed by the category oattachment to preformed professional self,o meaning that students wanted their preconceptions about therapy to be acknowledged by teachers. After training, participants experienced achieved recognition and, as a result, a sense of freedom to use their own judgment.

- AIM: although the median age of patients diagnosed with colon cancer is above 70 years, little is known about specific characteristics and management in the elderly. The aim of the study was to define characteristics of colon cancer in elderly patients and compare the quality of preoperative assessment and surgery with that of younger patients undergoing surgery for colon cancer.METHOD: data on 15.255 patients diagnosed with colon cancer between 2007 and 2010 were retrieved from the Swedish National Colon Cancer Register. Of these, 12.959 underwent surgical resection, 6.141 were 75 years or older while 6.818 were younger. The χ(2) test, Mann-Whitney U test and uni- and multivariable logistic regression analyses were used for comparison between groups.RESULTS: older patients were more likely to be female (54% older/48% younger) and have right-sided cancer (60% older/49% younger). Among patients who underwent resection, the elderly were less often evaluated regarding tumour stage prior to surgery (59% older/65% younger) and they were less often evaluated at a multidisciplinary team conference (26% older/34% younger). Elderly patients more frequently underwent emergency surgery (22% older/19% younger) despite having an earlier cancer stage. When adjusted for stage, fewer elderly patients underwent a radical curative procedure (OR for non-curative resection 1.19; 95% CI 1.06-1.33)CONCLUSION: routine management of patients with colon cancer is age-dependent. Patients 75 years and older are less often completely staged and less often evaluated at a multi-disciplinary team conference prior to surgery. Adjusted for stage, fewer elderly patients undergo curative resection.

Regulatory mutations in TBX3 disrupt asymmetric hair pigmentation underlying Dun camouflage colour in horses

- Dun is a wild-type coat color in horses characterized by pigment dilution with a striking pattern of dark areas termed primitive markings. Here we show that pigment dilution in Dun horses is due to radially asymmetric deposition of pigment in the growing hair caused by localized expression of the T-box 3 (TBX3) transcription factor in hair follicles, which in turn determines the distribution of hair follicle melanocytes. Most domestic horses are non-dun, a more intensely pigmented phenotype caused by regulatory mutations impairing TBX3 expression in the hair follicle, resulting in a more circumferential distribution of melanocytes and pigment granules in individual hairs. We identified two different alleles (non-dun1 and non-dun2) causing non-dun color. non-dun2 is a recently derived allele, whereas the Dun and non-dun1 alleles are found in ancient horse DNA, demonstrating that this polymorphism predates horse domestication. These findings uncover a new developmental role for T-box genes and new aspects of hair follicle biology and pigmentation.

- The rich fossil record of equids has made them a model for evolutionary processes(1). Here we present a 1.12-times coverage draft genome from a horse bone recovered from permafrost dated to approximately 560-780 thousand years before present (kyr BP)(2,3). Our data represent the oldest full genome sequence determined so far by almost an order of magnitude. For comparison, we sequenced the genome of a Late Pleistocene horse (43 kyr BP), and modern genomes of five domestic horse breeds (Equus ferus caballus), a Przewalski's horse (E. f. prze-walskii) and a donkey (E. asinus). Our analyses suggest that the Equus lineage giving rise to all contemporary horses, zebras and donkeys originated 4.0-4.5 million years before present (Myr BP), twice the conventionally accepted time to the most recent common ancestor of the genus Equus(4,5). We also find that horse population size fluctuated multiple times over the past 2 Myr, particularly during periods of severe climatic changes. We estimate that the Przewalski's and domestic horse populations diverged 38-72 kyr BP, and find no evidence of recent admixture between the domestic horse breeds and the Przewalski's horse investigated. This supports the contention that Przewalski's horses represent the last surviving wild horse population(6). We find similar levels of genetic variation among Przewalski's and domestic populations, indicating that the former are genetically viable and worthy of conservation efforts. We also find evidence for continuous selection on the immune system and olfaction throughout horse evolution. Finally, we identify 29 genomic regions among horse breeds that deviate from neutrality and show low levels of genetic variation compared to the Przewalski's horse. Such regions could correspond to loci selected early during domestication.

- The study aims to explore systematically the ideas of cure among young adults prior to psychoanalytic psychotherapy. Forty-six individuals aged 18 to 25 years who applied for psychotherapy underwent the Private Theories Interview (PTI). Twenty distinct categories of ideas of cure were identified. Based on these categories, a theoretical model was constructed with the dimensions, Approaching-Distancing and Doing-Receiving. Individuals were classified into types using "ideal type analysis." Seven ideal types were formed: Processing and Understanding, Mastering Through Own Will and Action, Talking, Discordant Ideas, Incoherent Ideas, Getting It Out, and Avoiding or Placing the Solution onto Others. New hypotheses emerged concerning ideas of cure as an important factor for psychotherapy matching, thus potentially predicting premature termination, alliance, and outcome.
