The number of studies in the area of self-care is growing and international researchers are increasingly developing self-care interventions to improve outcomes of individual patients and communities. ...However, growth of the evidence is still slow due to challenges with designing and testing self-care interventions. In this article we address major methodological challenges with regard to the definition of self-care, use of theory, and research design, intended to provide guidance to researchers in this field.
During the inaugural conference of the International Center for Self-Care Research held in Rome, Italy in June 2019 we identified important issues in existing self-care research. Discussion and literature review lead to eight recommendation for future self-care research.
In preparation, begin with a theoretically sound definition of self-care. In planning the intervention, build on and extend previous studies. Use theory to develop self-care interventions and consider translational models to guide development, evaluation and implementation of complex self-care interventions. Employ a study design that fits the current phase and objectives of the research and measure self-care and related factors carefully. In reporting, describe the sample and setting sufficiently so that others can draw conclusions about generalizability and applicability to their practice and patient population. In interpretation, describe how the intervention is assumed to work (causal assumptions) and its key components.
Our review of existing self-care research clearly illustrates that the recommendations we provide are needed if we are to substantially grow the evidence base supporting self-care. Embracing a core set of principles will allow us to build on each other's work.

Developing accurate but inexpensive methods for estimating above-ground carbon biomass is an important technical challenge that must be overcome before a carbon offset market can be successfully ...implemented in the United States. Previous studies have shown that LiDAR (light detection and ranging) is well-suited for modeling above-ground biomass in mature forests; however, there has been little previous research on the ability of LiDAR to model above-ground biomass in areas with young, aggrading vegetation. This study compared the abilities of discrete-return LiDAR and high resolution optical imagery to model above-ground carbon biomass at a young restored forested wetland site in eastern North Carolina. We found that the optical imagery model explained more of the observed variation in carbon biomass than the LiDAR model (adj-R(2) values of 0.34 and 0.18 respectively; root mean squared errors of 0.14 Mg C/ha and 0.17 Mg C/ha respectively). Optical imagery was also better able to predict high and low biomass extremes than the LiDAR model. Combining both the optical and LiDAR improved upon the optical model but only marginally (adj-R(2) of 0.37). These results suggest that the ability of discrete-return LiDAR to model above-ground biomass may be rather limited in areas with young, small trees and that high spatial resolution optical imagery may be the better tool in such areas.

Recently, the Galactic center has been reported to be a source of very high energy (VHE) g-rays by the CANGAROO, VERITAS, and HESS experiments. The energy spectra as measured by these experiments ...show substantial differences. In this Letter we present MAGIC observations of the Galactic center, resulting in the detection of a differential g-ray flux consistent with a steady, hard-slope power law, described as dN sub(g)/(dA dt dE) = (2.9 c 0.6) x 10 super(-12)(E/TeV) super(-2.2c0.2) cm super(-2) s super(-1) TeV super(-1). The g-ray source is centered at (R.A., decl.) = (17 super(h)45 super(m)20 super(s), -292'). This result confirms the previous measurements by the HESS experiment and indicates a steady source of TeV g-rays. We briefly describe the observational technique used and the procedure implemented for the data analysis, and we discuss the results in the perspective of different models proposed for the acceleration of the VHE g-rays.
Background
In 2011, a major outbreak of hemolytic‐uremic syndrome (HUS) and bloody diarrhea related to infections from Shiga toxin‐producing Escherichia coli O104 (STEC) occurred in Germany. While ...previous research has focused on the medical components of this disease, we aimed to investigate the course of health‐related quality of life (HrQoL) over 12 months including somatic and psychosocial risk factors. Furthermore, the influence of chronic fatigue (CF) on HrQoL was examined.
Methods
A prospective cohort study with n = 389 patients completing self‐report scales at baseline, after 6 months (participation rate: 79%) and after 12 months (participation rate: 77%). The courses of physical and mental HrQoL over the 12 month period were calculated by employing general linear mixed models.
Key Results
While the physical component score of HrQoL reached a score comparable to the general population, the mental component score remained below average 12 months after STEC infection. Female gender, prior psychiatric disorder, and prior traumatic events were risk factors for a worse HrQoL course after 12 months, while social support was identified to be protective. CF was associated with low HrQoL. In addition, the somatic symptom burden remained persistently high.
Conclusions & Inferences
Our results show high somatic and psychosocial burden in patients 12 months after STEC infection. We recommend considering the risk factors and protective factors of poor HrQoL early in the treatment of STEC or similar diseases. Patients who are suffering from persisting somatic symptoms, CF, and impaired HrQoL may require specific aftercare.
