Data from: Patient and disease characteristics associated with activation for self-management in patients with diabetes, chronic obstructive pulmonary disease, chronic heart failure and chronic renal disease: a cross-sectional survey study

Irene Bos-Touwen, Marieke Schuurmans, Evelyn M. Monninkhof, Yvonne Korpershoek, Lotte Spruit-Bentvelzen, Inge Ertugrul-Van Der Graaf, Niek De Wit & Jaap Trappenburg
A substantial proportion of chronic disease patients do not respond to self-management interventions, which suggests that one size interventions do not fit all, demanding more tailored interventions. To compose more individualized strategies, we aim to increase our understanding of characteristics associated with patient activation for self-management and to evaluate whether these are disease-transcending. A cross-sectional survey study was conducted in primary and secondary care in patients with type-2 Diabetes Mellitus (DM-II), Chronic Obstructive Pulmonary Disease...

Background: We determined the prevalence, incidence, and risk factors for epilepsy in Nigeria. Methods: We conducted a door-to-door survey to identify cases of epilepsy in three regions. We estimated age-standardized prevalence adjusted for non-response and sensitivity and the one-year retrospective incidence for active epilepsy. To assess potential risk factors, we conducted a case-control study by collecting sociodemographic and risk factor data. We estimated odds ratios (ORs) using logistic regression analysis and corresponding population attributable fractions...

Source data for: Human monoclonal antibodies against Staphylococcus aureus surface antigens recognize in vitro biofilm and in vivo implant infections

Lisanne De Vor
Implant-associated Staphylococcus aureus infections are difficult to treat because of biofilm formation. Bacteria in a biofilm are often insensitive to antibiotics and host immunity. Monoclonal antibodies (mAbs) could provide an alternative approach to improve the diagnosis and potential treatment of biofilm-related infections. Here we show that mAbs targeting common surface components of S. aureus can recognize clinically relevant biofilm types. The mAbs were also shown to bind a collection of clinical isolates derived from different...

Data from: Sex allocation adjustment to mating group size in a simultaneous hermaphrodite

Tim Janicke, Lucas Marie-Orleach, Katrien De Mulder, Eugene Berezikov, Peter Ladurner, Dita Brigida Vizoso & Lukas Schärer
Sex allocation theory is considered as a touchstone of evolutionary biology, providing some of the best supported examples for Darwinian adaptation. In particular, Hamilton’s local mate competition theory has been shown to generate precise predictions for extraordinary sex ratios observed in many separate-sexed organisms. In analogy to local mate competition, Charnov’s mating group size model predicts how sex allocation in simultaneous hermaphrodites is affected by the mating group size (i.e., the number of mating partners...

Challenging the established order: innovating clinical trials for amyotrophic lateral sclerosis

Ruben Van Eijk
Development of effective treatment for amyotrophic lateral sclerosis (ALS) has been hampered by disease heterogeneity,a limited understanding of underlying pathophysiology and methodological design challenges. Here we have evaluated two major themes in the design of pivotal, phase 3 clinical trials for ALS: (1) patient selection and (2) analytical strategy, and discussed potential solutions with the European Medicines Agency (EMA). Several design considerations were assessed using data from five placebo-controlled clinical trials (N = 988), four...

Data from: Genetics of plasminogen activator inhibitor-1 (PAI-1) in a Ghanaian population

Marquitta J. White, Nuri M. Kodaman, Reed H. Harder, Folkert W. Asselbergs, Douglas E. Vaughan, Nancy J. Brown, Jason H. Moore & Scott M. Williams
Plasminogen activator inhibitor 1 (PAI-1), a major modulator of the fibrinolytic system, is an important factor in cardiovascular disease (CVD) susceptibility and severity. PAI-1 is highly heritable, but the few genes associated with it explain only a small portion of its variation. Studies of PAI-1 typically employ linear regression to estimate the effects of genetic variants on PAI-1 levels, but PAI-1 is not normally distributed, even after transformation. Therefore, alternative statistical methods may provide greater...
