Pretreatment resistin levels are associated with erosive disease in early rheumatoid arthritis treated with disease-modifying anti-rheumatic drugs and infliximab

Objective: Resistin is an adipocytokine related to insulin resistance and inflammation. We investigated whether resistin is associated with disease activity and inflammation in disease-modifying anti-rheumatic drug (DMARD)-naive rheumatoid arthritis (RA) patients, whether it has predictive value for radiological disease progression, and whether tumour necrosis factor-alpha (TNF-alpha) is involved in these effects. Method: Ninety-nine patients with early, DMARD-naive RA participated in the NEO-RACo study. Patients were treated for the first 4 weeks with a combination of methotrexate, sulfasalazine, hydroxychloroquine, and prednisolone (FIN-RACo treatment). Thereafter, they were randomized to receive either infliximab or placebo added to the combination for 6 months. Patients were followed for 5 years. Disease activity was evaluated using the Disease Activity Score based on 28-joint count-erythrocyte sedimentation rate, radiographs were scored with the modified Sharp-van der Heijde method, and plasma resistin concentrations were measured by immunoassay. Human THP-1 macrophages were used in the in vitro studies. Results: A high resistin level at baseline was associated with active inflammatory disease and predicted more rapid radiological progression during 5 year follow-up. Adding infliximab to the DMARD combination delayed radiological progression and overcame the poor predictive value of resistin. Resistin increased TNF-alpha production in human macrophages, indicating a possible connection between resistin and TNF-alpha. Conclusion: The results suggest that high resistin concentration may be a useful marker to distinguish patients with an increased risk of erosive disease in early active RA, and that adding TNF-alpha antagonist to the traditional DMARD combination may delay radiological progression of the disease in these patients.Peer reviewe

Concealment of type 1 diabetes at work in Finland: a mixed-method study

Objectives To explore the possible reasons for concealing type 1 diabetes (T1D) at work. Methods The main set of data came from a cross-sectional survey (response rate 49.3%), the participants of which were 688 wage earners with T1D. Concealment of T1D was measured by asking respondents have they ever during their working career hidden their diabetes from their (A) colleagues and (B) line manager. Furthermore, semistructured interviews (n=20) were conducted to obtain deeper understanding. Questionnaire data were analysed using logistic regression analyses and qualitative interviews with inductive thematic analysis. Results About 30% of wage earners with T1D had concealed their condition during their working career from their colleagues and almost 20% from their line manager. Individuals aged 18–44 years age were more likely to conceal their T1D from their colleagues than older workers during their working career. Not disclosing T1D to the extended family (OR 5.24 (95% CI 2.06 to 13.35)), feeling an outsider at work (OR 2.47 (95% CI 1.58 to 3.84)), being embarrassed by receiving special attention at work (OR 1.99 (95% CI 1.33 to 2.96)) and neglecting treatment at work (OR 1.59 (95% CI 1.01 to 2.48)) were all associated with concealment of T1D from colleagues. The youngest age group of 18–24 years were more likely to conceal their T1D from their line managers than the older age groups during their working career. Not disclosing T1D to the extended family (OR 4.41 (95% CI 1.72 to 11.32)), feeling like an outsider at work (OR 2.51 (1.52 to 4.14)) and being embarrassed by receiving special attention at work (OR 1.81 (95% CI 1.13 to 2.91)) were associated with concealment of T1D from line managers. From the interviews, five main themes related to concealment emerged, expressing fears related to the consequences of telling: (1) being perceived as weak, (2) job discrimination, (3) unwanted attention, (4) being seen as a person who uses their T1D for seeking advantages and (5) losing privacy. Conclusions A considerable proportion of wage earners with T1D are concealing their diagnosis often because of feelings associated with stigma. Both overemphasis and underestimation of T1D at work by the colleagues or line manager may lead to concealing T1D and may thus be harmful to self-management of T1D. The obstacles in disclosing T1D might be diminished by giving adequate information at the workplace about the condition and its significance

Disclosure of type 1 diabetes at work among Finnish workers

© 2016 Diabetes UK.Aims: To determine which self-management factors and psychosocial work factors were associated with disclosing diabetes to colleagues, line managers and occupational health personnel among workers with Type 1 diabetes. Methods: A total of 767 working-aged respondents with Type 1 diabetes completed a Finnish cross-sectional survey named 'People with Type 1 Diabetes in Worklife'. Factor analysis was carried out, followed by logistic regressions to estimate the associations between self-management factors, psychosocial work factors and the likelihood of disclosure separately to colleagues, line managers and occupational health personnel. The models were adjusted for sociodemographic, diabetes-related and work-related variables. Results: A total of 52% of the respondents had disclosed their diabetes to their colleagues, 45% to occupational health personnel and 28% to their line manager. Receiving social support and having good psychosocial work ability were significantly associated with disclosure to colleagues, line managers and occupational health personnel. Relations at work were associated with disclosure to colleagues and the line manager. Furthermore, opportunity to self-manage diabetes at work was associated with disclosure to colleagues. Conclusions: Line managers and colleagues have a remarkable role to play in providing workplace support to workers with Type 1 diabetes. Disclosure of Type 1 diabetes should be encouraged as line managers can provide workers with the right support, implement work adaptations and facilitate job retention. As only half of respondents disclosed their Type 1 diabetes at work, further research is required into the reasons for and consequences of not disclosing a diagnosis

Discovery of a New Deeply Eclipsing SU UMa-Type Dwarf Nova, IY UMa (= TmzV85)

We discovered a new deeply eclipsing SU UMa-type dwarf nova, IY UMa, which experienced a superoutburst in 2000 January. Our monitoring revealed two distinct outbursts, which suggest a superoutburst interval of ~800 d, or its half, and an outburst amplitude of 5.4 mag. From time-series photometry during the superoutburst, we determined a superhump and orbital period of 0.07588 d and 0.0739132 d, respectively.Comment: 5 pages, 3 figures, accepted by PASJ lette

A Genetic Algorithm solver for pest management control in Island systems

Island conservation management is a truly multidisciplinary problem that requires considerable knowledge of the characteristics of the ecosystem, species and their interactions. Nevertheless, this can be translated into an optimisation problem. Essentially, within a limited budget, a manager needs to select the conservation actions according to expected payoffs (in terms of protecting or restoring desired species) versus cost (the amount of resources/money) required for the actions. This paper presents the problem in terms of a knapsack formulation and develops optimisation techniques to solve it. From this, decision-support software is being developed, tailored to meet the needs of pest control on islands for conservation managers. The solver uses a Genetic Algorithm and incorporates a simplified model of the problem. The solver derives strategies that reduce the number of threats, allowing the preservation of desired species. However, the problem model needs further refinement to derive truly realistic options for conservation managers

First detection of the growing humps at the rapidly rising stage of dwarf novae AL Com and WZ Sge

We report on time-series photometric observations in the earliest stages of superoutbursts of the extreme dwarf novae, AL Com and WZ Sge, which started on 2001 May after the 6 years quiescence and on 2001 July after the 23 years quiescence, respectively. We detected growth of ``early superhumps'' during the each rising stage. Our observations reject the mass transfer instability for the trigger of the superoutburst of WZ Sge stars, and show the existence of some relations between the ``early superhumps'' and the spiral structure, which give a hint of the origin of the ``early superhumps.''Comment: 4 pages, 4 figures, A&A macro in latex format, accepted to A&A letter

Dual-Earner Family Policies at Work for Single-Parent Families

Family dynamics are changing and single-parent families are becoming more common across countries. In their flagship report “Progress of the World’s Women, 2019–2020,” UN Women (2019) demonstrated that, contrary to popular belief, couples with children do not constitute a majority of all families, but rather there are many different types of families. Single parenthood is considered a “new social risk” in poverty and inequality (Bonoli, 2013). Therefore, policy makers and legislators have designed targeted policy specifically for single parents, such as targeted child benefits to single parents. In addition, legislation and social policy have been designed and implemented specifically for single parents, such as child support and family law such as child custody and shared residence. This study takes a different approach, based on the universalist argument that without adequate social protection that benefits all families, those families that are more vulnerable are often hit the hardest. We focus on family policies, and specifically we examine whether and to what extent single parents benefit from the same family policies that are available to all families with children

Disaccharide topology induces slow down in local water dynamics

Molecular level insight into water structure and structural dynamics near proteins, lipids and nucleic acids is critical to the quantitative understanding of many biophysical processes. Un- fortunately, understanding hydration and hydration dynamics around such large molecules is challenging because of the necessity of deconvoluting the effects of topography and chemical heterogeneity. Here we study, via classical all atom simulation, water structure and structural dynamics around two biologically relevant solutes large enough to have significant chemical and topological heterogeneity but small enough to be computationally tractable: the disaccharides Kojibiose and Trehalose. We find both molecules to be strongly amphiphilic (as quantified from normalized local density fluctuations) and to induce nonuniform local slowdown in water translational and rotational motion. Detailed analysis of the rotational slowdown shows that while the rotational mechanism is similar to that previously identified in other aqueous systems by Laage, Hynes and coworkers, two novel characteristics are observed: broadening of the transition state during hydrogen bond exchange (water rotation) and a subpopulation of water for which rotation is slowed because of hindered access of the new accepting water molecule to the transition state. Both of these characteristics are expected to be generic features of water rotation around larger biomolecules and, taken together, emphasize the difficulty in transferring insight into water rotation around small molecules to much larger amphiphilic solutes.This work is part of the research program of the “Stichting voor Fundamenteel Onderzoek der Materie (FOM)” which is financially supported by the “Nederlandse organisatie voor Wetenschap- pelijk Onderzoek (NWO)”.
