In this work, we show how and why the interactions between charged cubic colloids range from radially isotropic to strongly directionally anisotropic, depending on tuneable factors. Using molecular dynamics simulations, we illustrate the effects of typical solvents to complement experimental investigations of cube assembly. We find that in low-salinity water solutions, where cube self-assembly is observed, the colloidal shape anisotropy leads to the strongest attraction along the corner-to-corner line, followed by edge-to-edge, with a face-to-face configuration of the cubes only becoming energetically favorable after the colloids have collapsed into the van der Waals attraction minimum.

Objectives: To develop systematically a national research agenda for general practice involving general practitioners, researchers, patients and other relevant stakeholders in healthcare.
Background: Despite the considerable impact of migraine, the use of preventive medication in primary care is limited. Only about 5% of migraine patients who qualify for prophylaxis actually receive it, and adherence is far from optimal.
Aim: To explore the opinions of GPs regarding preventive medication for migraine.
Background: Prophylactic treatment is an important but under-utilised option for the management of migraine. Patients and physicians appear to have reservations about initiating this treatment option. This paper explores the opinions, motives and expectations of patients regarding prophylactic migraine therapy.

We investigated whether a proactive approach to patients with migraine, including an educational intervention for general practitioners, led to a decrease in headache and associated costs.
Methods: We conducted a pragmatic randomized controlled trial.
Migraine patients who experience an average of 2 or more attacks per month are eligible for preventive treatment as well as treatment for acute attacks. The decision to offer preventative treatment is also made on the basis of the average attack duration, severity of the attacks, and response to attack treatment. Prior to initiating preventive treatment, the average attack frequency per month should be assessed, preferably by means of a headache diary over a number of months, as attack frequency is extremely variable.

The aim of this study is to investigate how many patients use prophylaxis or would like to use them, and which aspects of migraine contribute to the choice to use prophylactic treatment. In a cross-sectional survey in three general practices, patients were selected who were diagnosed with migraine or had prescriptions for migraine medication.
