Identifying client characteristics to predict homecare use more accurately: a Delphi-study involving nurses and homecare purchasing specialists.

Background: Case-mix based prospective payment of homecare is being implemented in several countries to work towards more efficient and client-centred homecare. However, existing models can only explain a limited part of variance in homecare use, due to their reliance on health- and function-related client data. It is unclear which predictors could improve predictive power of existing case-mix models.

Using machine learning to assess the predictive potential of standardized nursing data for home healthcare case-mix classification.

Background: The Netherlands is currently investigating the feasibility of moving from fee-for-service to prospective payments for home healthcare, which would require a suitable case-mix system. In 2017, health insurers mandated a preliminary case-mix system as a first step towards generating information on client differences in relation to care use. Home healthcare providers have also increasingly adopted standardized nursing terminology (SNT) as part of their electronic health records (EHRs), providing novel data for predictive modelling.

Development of a casemix classification to predict costs of home care in the Netherlands: a study protocol.

Introduction: Compared with fee-for-service systems, prospective payment based on casemix classification is thought to promote more efficient, needs-based care provision. We aim to develop a casemix classification to predict the costs of home care in the Netherlands.

Methods And Analysis: The research is designed as a multicentre, cross-sectional cohort study using quantitative methods to identify the relative cost predictors of home care and combine these into a casemix classification, based on individual episodes of care.

Absence of long-range diffusion of OmpA in E. coli is not caused by its peptidoglycan binding domain.

Background: It is widely believed that integral outer membrane (OM) proteins in bacteria are able to diffuse laterally in the OM. However, stable, immobile proteins have been identified in the OM of Escherichia coli. In explaining the observations, a hypothesized interaction of the immobilized OM proteins with the underlying peptidoglycan (PG) cell wall played a prominent role.

Direct interactions of early and late assembling division proteins in Escherichia coli cells resolved by FRET.

The bacterial cell division machinery is organized in the so-called divisome composed of highly dynamic but low abundant interacting (membrane-bound) proteins. In order to elucidate the molecular interactions between these proteins, we developed a robust background-insensitive quantitative spectral unmixing method for estimating FRET efficiencies at near endogenous protein levels using fluorescent protein fusions. The assembly of the division machinery of Escherichia coli occurs in two steps that are discrete in time: first the FtsZ-ring and the so-called early localizing proteins that together seem to prepare the division assembly at midcell.

Differential bacterial surface display of peptides by the transmembrane domain of OmpA.

Peptide libraries or antigenic determinants can be displayed on the surface of bacteria through insertion in a suitable outer membrane scaffold protein. Here, we inserted the well-known antibody epitopes 3xFLAG and 2xmyc in exterior loops of the transmembrane (TM) domain of OmpA. Although these highly charged epitopes were successfully displayed on the cell surface, their levels were 10-fold reduced due to degradation.

Superlubricity of graphite.

Using a home-built frictional force microscope that is able to detect forces in three dimensions with a lateral force resolution down to 15 pN, we have studied the energy dissipation between a tungsten tip sliding over a graphite surface in dry contact. By measuring atomic-scale friction as a function of the rotational angle between two contacting bodies, we show that the origin of the ultralow friction of graphite lies in the incommensurability between rotated graphite layers, an effect proposed under the name of "superlubricity" [Phys.
