- Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms.

- Background: Several melanoma susceptibility genes have been identified. As part of the international genetic research programme of the GenoMEL consortiums research on genetic mutations in melanoma families, the aim of this study was to examine family members' views about their risk of melanoma, gene testing and genetic research. Methods: Self-report data were gathered using online and paper-based surveys available in four languages among 312 individuals (62% from Europe, 18% from Australia, 13% from the United States of America (USA) and 7% from Israel). Results: Fifty three percent had been diagnosed with a melanoma, and 12% had a positive susceptibility gene test result. Respondents with many moles and freckles were more likely to perceive themselves at risk for developing melanoma (odds ratio [OR](Freckles) = 2.24 with 95% confidence interval [CI] = 1.18-4.26; ORMany (moles) = 6.92, 95% CI = 2.37-20.23). Respondents who had received a non-informative (negative) genetic test result were much less likely to perceive themselves at increased risk (OR = 0.17, 95% CI = 0.04-0.73). Safe-guards were perceived as important to protect genetic information, but there was also support for the storage and exchange of such information. Overall, respondents were in favour of genetic testing, even if current knowledge about melanoma risk genes is still limited. Contrary to previous studies, participants reported that a non-informative (negative) genetic test result, although not necessarily indicative of lower risk of melanoma, would be likely to reduce their practise of preventive behaviours. Conclusions: Participants were influenced by their phenotype and test results in risk estimations. They expressed positive views on genetic research and towards genetic testing, but reported that a non-informative (negative) test result might be associated with an (erroneous) perception of reduced risk and fewer preventive behaviours. These results highlight the urgency of improving the quality of genetic counselling and increasing the effectiveness of communication regarding genetic test results. (C) 2012 Elsevier Ltd.

Hematopoietic cell transplantation utilization and outcomes for primary plasma cell leukemia in the current era

Journal article (peer-reviewed)abstract
- The outcomes of patients with primary plasma cell leukemia (pPCL) after undergoing hematopoietic cell transplantation (HCT) in the novel agent era are unknown. We report outcomes of 348 patients with pPCL receiving autologous (auto-) HCT (n = 277) and allogeneic (allo-) HCT (n = 71) between 2008 and 2015. Median age was 60 years and 56 years for auto- and allo-HCT respectively. For auto-HCT, the 4-year outcomes were: non-relapse mortality (NRM) 7% (4-11%), relapse (REL) 76% (69-82%), progression-free survival (PFS) 17% (13-23%), and overall survival (OS) 28% (22-35%). Karnofsky performance status (KPS) > 90 and >= very good partial response (VGPR) predicted superior OS in multi-variate analysis for auto-HCT. For allo-HCT, the 4-year outcomes were: NRM 12% (5-21%), REL 69% (56-81%), PFS 19% (10-31%), and OS 31% (19-44%). Compared with prior CIBMTR pPCL patients (1995-2006), inferior survival was noted in the current cohort (3-year OS, 39% vs. 38% in allo-HCT, and 62% vs. 35% in auto-HCT) respectively. However, we noted an increased HCT utilization, from 12% (7-21%) in 1995 to 46% (34-64%) in 2009 using SEER data (available till 2009). Despite modern induction translating to higher proportion receiving HCT, the outcomes remain poor in pPCL patients, mainly derived by high relapse rates post-HCT.

Increases in soil aggregation following phosphorus additions in a tropical premontane forest are not driven by root and arbuscular mycorrhizal fungal abundances
- 2016

Journal article (peer-reviewed)abstract
- Tropical ecosystems have an important role in global change scenarios, in part because they serve as a large terrestrial carbon pool. Carbon protection is mediated by soil aggregation processes, whereby biotic and abiotic factors influence the formation and stability of aggregates. Nutrient additions may affect soil structure indirectly by simultaneous shifts in biotic factors, mainly roots, and fungal hyphae, but also via impacts on abiotic soil properties. Here, we tested the hypothesis that soil aggregation will be affected by nutrient additions primarily via changes in arbuscular mycorrhizal fungal (AMF) hyphae and root length in a pristine tropical forest system. Therefore, the percentage of water-stable macroaggregates (> 250 µm) (WSA) and the soil mean weight diameter (MWD) was analyzed, as well as nutrient contents, pH, root length, and AMF abundance. Phosphorus additions significantly increased the amount of WSA, which was consistent across two different sampling times. Despite a positive effect of phosphorus additions on extra-radical AMF biomass, no relationship between WSA and extra-radical AMF nor roots was revealed by regression analyses, contrary to the proposed hypothesis. These findings emphasize the importance of analyzing soil structure in understudied tropical systems, since it might be affected by increasing nutrient deposition expected in the future.

Comorbid disease burden among MS patients 1968-2012 : A Swedish register-based cohort study
- 2021

In: Multiple Sclerosis Journal. - : Sage Publications. - 1352-4585 .- 1477-0970. ; 27:2, s. 268-280

Journal article (peer-reviewed)abstract
- BACKGROUND: People with multiple sclerosis (pwMS) have increased comorbid disease (CMD) risk. Most previous studies have not considered overall CMD burden.OBJECTIVE: To describe lifetime CMD burden among pwMS.METHODS: PwMS identified using Swedish registers between 1968 and 2012 (n = 25,476) were matched by sex, age, and county of residence with general-population comparators (n = 251,170). Prevalence, prevalence ratios (PRs), survival functions, and hazard ratios by MS status, age, and time period compared seven CMD: autoimmune, cardiovascular, depression, diabetes, respiratory, renal, and seizures.RESULTS: The magnitude of the PRs for each CMD and age group decreased across time, with higher PRs in earlier time periods. Before 1990, younger age groups had higher PRs, and after 1990, older age groups had higher PRs. Male pwMS had higher burden compared with females. Overall, renal, respiratory, and seizures had the highest PRs. Before 2001, 50% of pwMS received a first/additional CMD diagnosis 20 years prior to people without MS, which reduced to 4 years after 2001. PwMS had four times higher rates of first/additional diagnoses in earlier time periods, which reduced to less than two times higher in recent time periods compared to people without MS.CONCLUSION: Swedish pwMS have increased CMD burden compared with the general population, but this has reduced over time.
