- Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.522.7) and 16.5 cm (13.319.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries.

- Background: One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the age standardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are aff ecting the number of adults with diabetes.Methods: We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes prevalence-defined as fasting plasma glucose of 7.0 mmol/L or higher, or history of diagnosis with diabetes, or use of insulin or oral hypoglycaemic drugs-in 200 countries and territories in 21 regions, by sex and from 1980 to 2014. We also calculated the posterior probability of meeting the global diabetes target if post-2000 trends continue.Findings: We used data from 751 studies including 4372000 adults from 146 of the 200 countries we make estimates for. Global age-standardised diabetes prevalence increased from 4.3% (95% credible interval 2.4-17.0) in 1980 to 9.0% (7.2-11.1) in 2014 in men, and from 5.0% (2.9-7.9) to 7.9% (6.4-9.7) in women. The number of adults with diabetes in the world increased from 108 million in 1980 to 422 million in 2014 (28.5% due to the rise in prevalence, 39.7% due to population growth and ageing, and 31.8% due to interaction of these two factors). Age-standardised adult diabetes prevalence in 2014 was lowest in northwestern Europe, and highest in Polynesia and Micronesia, at nearly 25%, followed by Melanesia and the Middle East and north Africa. Between 1980 and 2014 there was little change in age-standardised diabetes prevalence in adult women in continental western Europe, although crude prevalence rose because of ageing of the population. By contrast, age-standardised adult prevalence rose by 15 percentage points in men and women in Polynesia and Micronesia. In 2014, American Samoa had the highest national prevalence of diabetes (>30% in both sexes), with age-standardised adult prevalence also higher than 25% in some other islands in Polynesia and Micronesia. If post-2000 trends continue, the probability of meeting the global target of halting the rise in the prevalence of diabetes by 2025 at the 2010 level worldwide is lower than 1% for men and is 1% for women. Only nine countries for men and 29 countries for women, mostly in western Europe, have a 50% or higher probability of meeting the global target.Interpretation: Since 1980, age-standardised diabetes prevalence in adults has increased, or at best remained unchanged, in every country. Together with population growth and ageing, this rise has led to a near quadrupling of the number of adults with diabetes worldwide. The burden of diabetes, both in terms of prevalence and number of adults aff ected, has increased faster in low-income and middle-income countries than in high-income countries.

- AIM: The aim of this study was to investigate the feasibility and cost-utility of a school-based cognitive-behavioral (CB) depression prevention program.METHODS: A quasi-experimental trial with an intervention group and a control group, with follow-up measurements obtained at three and 12 months after baseline, was conducted. The setting was six Swedish municipalities. The participants were students in grade 8 (median age: 14). A total of 462 students (79% girls) were allocated to the school-based CB prevention program, and 486 students (46% girls) were allocated to the control group. The school-based CB prevention program, Depression in Swedish Adolescents (DISA), was presented by school health service staff and teachers once per week for 10 weeks.RESULTS: The main outcome measures were self-reported depressive symptoms and self-rated health; the secondary outcome measures were adherence and cost-utility. The intervention group decreased their self-reported depressive symptoms (as measured by the Center for Epidemiological Studies Depression Scale) and improved their self-rated health (as measured by the visual analog scale) at the 12-month follow-up more than the control group ( p < .05).CONCLUSIONS: Given the challenges of conducting a study in a complex, everyday school setting with baseline differences between the intervention and control group, it is difficult to make accurate interpretations of the effectiveness of the intervention. However, with these limitations in mind, the results indicate that the DISA program is a feasible school-based prevention program.

- Alanine/agarose gel and alanine films in stacks have been used for measurements of absorbed dose around an HDR 192Ir source in a vaginal cylinder-applicator, with and without a 180° tungsten shield. The gel and the films were analysed by means of ESR spectroscopy and calibrated against an ion chamber in a 4 MV photon beam to obtain absolute dose values. The gel serves as both dosimeter and phantom material, and the thin (130 μm) films are used to achieve an improved spatial resolution in the dose estimations.Experimental values were compared with Monte Carlo simulations using two different codes. Results from the measurements generally agree with the simulations to within 5%, for both the alanine/agarose gel and the alanine films.

- Adipose tissue is an endocrine organ that produces and secretes adipokines. The aim of this study was to identify genes predominantly expressed in human subcutaneous adipocytes. For this purpose, an algorithm was developed and DNA microarray expression profiles from 33 human tissues and cell types were used to select genes. Inhibin beta B (INHBB; coding for the activin betaB subunit) was identified and high expression in adipocytes was confirmed by real-time PCR and immunohistochemistry. INHBB expression in adipose tissue was down regulated by diet-induced weight loss (p<0.001). Furthermore, INHBB expression was positively correlated to total (p<0.001) and subcutaneous (p<0.01) adipose tissue areas and serum levels of fasting insulin (p<0.01) and cholesterol (p<0.05). In conclusion, INHBB expression was high in human adipocytes, reduced by weight loss and adipose tissue INHBB mRNA levels correlated to metabolic risk factors. This suggests that activin B produced in adipocytes may play a role in the metabolic syndrome.

CD4+CD57+ T cells derived from peripheral blood do not support immunoglobulin production by B cells
- 1995

Ingår i: Cellular Immunology. - : Elsevier BV. - 0008-8749. ; 163:2, s. 245-253

Tidskriftsartikel (refereegranskat)abstract
- A small subpopulation of CD4+ T cells found in peripheral blood coexpresses the CD57+ marker normally found on, e.g., NK cells. It is known that this population occurs in a higher frequency in certain diseases. The same antigen has also been shown to be expressed on CD4+ T cells derived from germinal centers. The localization of this cell population to specialized lymphoid structures suggests that it may play a role in the evolution of the antibody response following antigenic stimulation in vivo. We have examined the ability of peripheral blood helper T cells coexpressing CD57 to participate in B cell activation/differentiation and evaluated their responses to polyclonal stimulation. The CD4+CD57+ T cells do not express mRNA for a number of different cytokines or for the CD40 ligand after activation in vitro. Furthermore these cells do not induce differentiation of B cells into immunoglobulin-producing cells. Consequently, despite their CD4 phenotype and their ability to be activated, to express the IL-2 receptor, and to enter into the cell cycle, they do not act as T helper cells under conditions where CD4+/CD57- cells normally do so. The findings suggest that this peripheral blood helper T cell population is functionally different from regular CD4+ T cells. The basis for the lack of proper costimulatory signals for immunoglobulin production might be related to the low expression of CD28.

- Germinal centers (GC) are well-defined areas in lymphoid organs were B cells proliferate and differentiate in response to T-cell-dependent antigens. The GC comprises B cells, follicular dendritic cells, tangible body macrophages, and a low number of CD4+ T cells. A large portion of these T cells expresses CD57. We have examined the ability of the CD4+CD57+ GC T cells to become activated and to take part in B cell activation processes, These T cells coexpress CD45RO, CD69, CD28, and upon mitogenic stimulation CD25, The cell population was found neither to containe nor to be able to produce any specific mRNA for IL-2, IL-4, and IFN-γ upon activation. Levels of mRNA encoding CD40 ligand was also undetectable under similar conditions. Furthermore, in contrast to ordinary CD4+ T cells, this population expressing CD57 was unable to induce B cells to Ig production in the presence of pokeweed mitogen or SEA unless IL-2 was added to the cultures, However, despite their apparent lack of function CD4+CD57+ GC T cells were found to rescue GC B cells from cell death in vitro to the same extent as CD4+CD57- T(h) cells, The phenotypical and functional differences found between these T cells and regular T(h)-cells suggest that they either represent a T cell subset with distinct properties within the GC yet to be determined or that they represent T cells, Irate in the immune response, having lost most of their original functions and capabilities.
