- Biallelic germline ERCC6L2 variants strongly predispose to bone marrow failure (BMF) and myeloid malignancies characterized by somatic TP53-mutated clones and erythroid predominance. We present a series of 52 subjects (35 families) with ERCC6L2 biallelic germline variants collected retrospectively in 11 centers globally, including follow-up of 1165 person-years. At initial investigations, 32 individuals were diagnosed with BMF and 15 with a hematological malignancy (HM). Subjects presented with 19 different variants across ERCC6L2, and we identified a founder mutation c.1424delT in the Finnish patients. The median age of subjects at baseline was 18 years (range 2-65). Changes in complete blood count (CBC) were mild despite severe bone marrow hypoplasia and somatic TP53 mutations, with no significant difference between subjects with or without (HM). Signs of a progressive disease were increasing TP53 variant allele frequency, dysplasia in megakaryocytes and/or erythroid lineage, and erythroid predominance in bone marrow morphology. The median age at onset of HM was 37.0 years (95% CI: 31.5-42.5; range 12-65). Overall survival (OS) at 3 years was 95% (95% CI: 85-100) and 19% (95% CI: 0-39) for patients with BMF and HM, respectively. Patients with myelodysplastic syndrome or acute myeloid leukemia with mutated TP53 undergoing hematopoietic stem cell transplantation had a poor outcome: 3-year OS is 28% (95% CI: 0-61). Our results demonstrate the importance of early recognition and active surveillance of patients with biallelic germline ERCC6L2 variants.

- With the (RB)-B-3-LAND setup at GSI we have measured exclusive relative-energy spectra of the Coulomb dissociation of C-18 at a projectile energy around 425A MeV on a lead target, which are needed to determine the radiative neutron-capture cross sections of C-17 into the ground state of C-18. Those data have been used to constrain theoretical calculations for transitions populating excited states in C-18. This allowed to derive the astrophysical cross section sigma(n gamma)*. accounting for the thermal population of C-17 target states in astrophysical scenarios. The experimentally verified capture rate is significantly lower than those of previously obtained Hauser-Feshbach estimations at temperatures T-9

- Background and objective: We explored which clinical and biochemical variables predict conversion from clinically isolated syndrome (CIS) to clinically definite multiple sclerosis (CDMS) in a large international cohort. Methods: Thirty-three centres provided serum samples from 1047 CIS cases with at least two years' follow-up. Age, sex, clinical presentation, T2-hyperintense lesions, cerebrospinal fluid (CSF) oligoclonal bands (OCBs), CSF IgG index, CSF cell count, serum 25-hydroxyvitamin D3 (25-OH-D), cotinine and IgG titres against Epstein-Barr nuclear antigen 1 (EBNA-1) and cytomegalovirus were tested for association with risk of CDMS. Results: At median follow-up of 4.31 years, 623 CIS cases converted to CDMS. Predictors of conversion in multivariable analyses were OCB (HR = 2.18, 95% CI = 1.71-2.77, p < 0.001), number of T2 lesions (two to nine lesions vs 0/1 lesions: HR = 1.97, 95% CI = 1.52-2.55, p < 0.001; >9 lesions vs 0/1 lesions: HR = 2.74, 95% CI = 2.04-3.68, p < 0.001) and age at CIS (HR per year inversely increase = 0.98, 95% CI = 0.98-0.99, p < 0.001). Lower 25-OH-D levels were associated with CDMS in univariable analysis, but this was attenuated in the multivariable model. OCB positivity was associated with higher EBNA-1 IgG titres. Conclusions: We validated MRI lesion load, OCB and age at CIS as the strongest independent predictors of conversion to CDMS in this multicentre setting. A role for vitamin D is suggested but requires further investigation.

Aktivt Åldrande – individuellt anpassade måltidslösningar för hälsa och livskvalitet hos äldre – Beställning och distribution av mat för den äldre
- 2015

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- ”Active Ageing – Personalised food and meal solutions for health and quality of life” (Aktivt åldrande – individuellt anpassade måltidslösningar för hälsa och livskvalitet hos äldre. Diarienr 2013-02780) is a project that aims to maintain the quality of life and autonomy of older persons, through individual and personalised meal solutions that fit their needs and requirements. The target group are primarily the age 75 or older. Five work packages are included in the project. This report describes the work package that had the scope of developing a concept for the ordering, distribution and delivery of meal to the elderly. Refrigeration technology and the cold-chain will play an important role in the concept by preserving the safety and quality of foods during its transportation to the elderly. Refrigeration technology and the cold-chain will also make it possible to prepare specific types of foods that meet the demand of the elderly. In particular for the elderly consumers that would like to eat at home and decrease their independency and overall quality of life. It is also important the value chain and concept for the business model must be flexible and taking into account needs from the elderly consumers at all stages, starting from ordering the meal, handling in the household and disposing of the packaging material. An interdisciplinary approach – combining knowledge of ICT (information and communications technology) – Technology, food quality, packaging, logistic, sensory, and waste/return systems for the food that is distributed is increasingly necessary. As the demand for food for the elderly is on the rise, the development of new products, models and services might be facilitated by collaborating with SMEs (micro, small and mediumsized enterprises) and other business partners interested in delivering solutions for the elderly consumers. The concept for the ordering, distribution and delivery of meal to the elderly developed in the project can be used by other end users and/or for other products and services. Key words: : Aktivt åldrande, distribution, energi, IKT, IoT-sensorer, kvalitet, kyla, livsmedel, säkerhet, teknik, åldrande befolkning
