Standardising Through Software

Since its inception in 1948, the World Health Organization (WHO) has been instrumental in setting standards for monitoring and evaluation of public health interventions and health service delivery. This paper focuses on the way in which these standards are operationalized through health indicators and analytical tools. We describe and discuss a concrete attempt by WHO to achieve this by embedding indicators and analytical outputs in a health information software that is used in a majority of the world’s least developed nations. We analyse this phenomenon by using a concept of fluid standards, and challenge the ‘conventional’ perspective on standards as fully specified and unequivocal outputs of formal standardisation processes

P for Platform. Architectures of large-scale participatory design

Participatory Design (PD) has traditionally been committed to extensive interaction between developers and situated users to mitigate the disempowering consequences of computerization, such as the deskilling of labour workers. However, the widespread adoption of off-the-shelf software and the emergence of complex information system architectures with interdependencies across user groups and organizations challenge the applicability of traditional custom PD. Pressure is put on PD to scale with initiatives that span an increasing number and distribution of heterogeneous settings, developers, users and uses over time. In this article, we follow a PD project that started out in post-apartheid South Africa more than two decades ago. The project, which centres on the development of a software product for decentralised public health care management, has since grown into a venture with a significant footprint in the Global South. In order to problematise the scaling of key aspects of PD, such as the politics of design, the nature of participation and participatory design techniques, we first review extant literature and develop a classification of four different types of PD with respect to scale. We then apply the typology to our empirical case to discuss PD in relation to architectural traits at different stages of project scale. We contribute to PD literature by addressing the exploratory research question: What role does architecture play in large scale PD? Specifically, the study highlights how an emergent platform architecture and its surrounding ecosystem co-constitute a platform for participation in design

Definition, discrimination, diagnosis and treatment of central breathing disturbances during sleep

The complexity of central breathing disturbances during sleep has become increasingly obvious. They present as central sleep apnoeas (CSAs) and hypopnoeas, periodic breathing with apnoeas, or irregular breathing in patients with cardiovascular, other internal or neurological disorders, and can emerge under positive airway pressure treatment or opioid use, or at high altitude. As yet, there is insufficient knowledge on the clinical features, pathophysiological background and consecutive algorithms for stepped-care treatment. Most recently, it has been discussed intensively if CSA in heart failure is a "marker" of disease severity or a "mediator" of disease progression, and if and which type of positive airway pressure therapy is indicated. In addition, disturbances of respiratory drive or the translation of central impulses may result in hypoventilation, associated with cerebral or neuromuscular diseases, or severe diseases of lung or thorax. These statements report the results of an European Respiratory Society Task Force addressing actual diagnostic and therapeutic standards. The statements are based on a systematic review of the literature and a systematic two-step decision process. Although the Task Force does not make recommendations, it describes its current practice of treatment of CSA in heart failure and hypoventilation.status: publishe

Multiomics analysis of rheumatoid arthritis yields sequence variants that have large effects on risk of the seropositive subset

Objectives To find causal genes for rheumatoid arthritis (RA) and its seropositive (RF and/or ACPA positive) and seronegative subsets. Methods We performed a genome-wide association study (GWAS) of 31 313 RA cases (68% seropositive) and ~1 million controls from Northwestern Europe. We searched for causal genes outside the HLA-locus through effect on coding, mRNA expression in several tissues and/or levels of plasma proteins (SomaScan) and did network analysis (Qiagen). Results We found 25 sequence variants for RA overall, 33 for seropositive and 2 for seronegative RA, altogether 37 sequence variants at 34 non-HLA loci, of which 15 are novel. Genomic, transcriptomic and proteomic analysis of these yielded 25 causal genes in seropositive RA and additional two overall. Most encode proteins in the network of interferon-alpha/beta and IL-12/23 that signal through the JAK/STAT-pathway. Highlighting those with largest effect on seropositive RA, a rare missense variant in STAT4 (rs140675301-A) that is independent of reported non-coding STAT4-variants, increases the risk of seropositive RA 2.27-fold (p=2.1×10−9), more than the rs2476601-A missense variant in PTPN22 (OR=1.59, p=1.3×10−160). STAT4 rs140675301-A replaces hydrophilic glutamic acid with hydrophobic valine (Glu128Val) in a conserved, surface-exposed loop. A stop-mutation (rs76428106-C) in FLT3 increases seropositive RA risk (OR=1.35, p=6.6×10−11). Independent missense variants in TYK2 (rs34536443-C, rs12720356-C, rs35018800-A, latter two novel) associate with decreased risk of seropositive RA (ORs=0.63–0.87, p=10−9–10−27) and decreased plasma levels of interferon-alpha/beta receptor 1 that signals through TYK2/JAK1/STAT4. Conclusion Sequence variants pointing to causal genes in the JAK/STAT pathway have largest effect on seropositive RA, while associations with seronegative RA remain scarce

Objectives To find causal genes for rheumatoid arthritis (RA) and its seropositive (RF and/or ACPA positive) and seronegative subsets. Methods We performed a genome-wide association study (GWAS) of 31 313 RA cases (68% seropositive) and similar to 1 million controls from Northwestern Europe.
