The prevalence of diabetes and its associated complications, such as cardiovascular disease (CVD), has increased over recent years and is expected to continue to rise dramatically. People with diabetes have a poor prognosis, with a substantially increased risk of coronary heart disease, coronary death, non-fatal myocardial infarction, stroke, and other vascular deaths compared with non-diabetic subjects. Conversely, studies have also shown that many patients with CVD have undiagnosed dysglycaemia and that already impaired glucose tolerance and newly detected diabetes are associated with an impaired prognosis. Thus, screening for such conditions, preferably with oral glucose tolerance testing, should be performed in all patients with CVD. Guidelines advocate a multifactorial approach to the management of prediabetes, diabetes and CVD. This includes lifestyle modifications as well as targets for glycaemic control, blood pressure, lipids, and other cardiometabolic risk factors. Although clinical trial data have demonstrated that target-driven strategies can improve outcomes in patients with diabetes, the implementation and execution of these regimens in clinical practice needs to improve.

Severe behaviour problems (SBPs) in early childhood include oppositional and aggressive behaviours and predict negative mental health outcomes later in life. Although effective treatments for this group are available and numerous clinical practice guidelines have been developed to facilitate the incorporation of evidence-based treatments in clinical decision-making (NICE, 2013), many children with SBPs remain unresponsive to treatment (Lahey & Waldman, 2012). At present, it is unknown how many countries in Europe possess official clinical guidelines for SBPs diagnosis and treatment and what is their perceived utility. The aim was to create an inventory of clinical guidelines (and associated critical needs) for the diagnostics and treatment of SBPs in youth mental health across Europe according to academic experts and mental health clinicians’ opinions. To investigate the aim, two separate online semi-structured questionnaires were used, one directed at academics (N=28 academic experts; 23 countries), and the other at clinicians (N=124 clinicians; 24 countries). Three key results were highlighted. First, guidelines for SBPs are perceived as beneficial by both experts and clinicians. However, their implementation needs to be reinforced and content better adapted to daily practice. Improvements may include taking a multifactorial approach to assessment and treatment, involving the systems around the child, and multidisciplinary collaboration. Second, academic experts and clinicians support the need for further developing national / European guidelines. Finally, future guidelines should address current challenges identified by clinicians to be more applicable to daily practice.

Purpose – The purpose of this paper is to investigate the multi-skilled workers assignment problem in complex assembly systems such as aircraft assembly lines. An adaptive binary particle swarm optimization (A-BPSO) algorithm is proposed, which is used to balance the workload of both assembly stations and processes and to minimize the human cost. Design/methodology/approach – Firstly, a cycle time model considering the cooperation of multi-skilled workers is constructed. This model provides a quantitative description of the relationship between the cycle time and multi-skilled workers by means of revising the standard learning curve with the “Partition-And-Accumulate” method. Then, to improve the accuracy and stability of the current heuristic algorithms, an A-BPSO algorithm that suits for the discrete optimization problems is proposed to assign multi-skilled workers to assembly stations and processes based on modified sigmoid limiting function. Findings – The proposed method has been successfully applied to a practical case, and the result justifies its advantage as well as adaptability to both theory and engineering application. Originality/value – A novel cycle time model considering cooperation of multi-skilled workers is constructed so that the calculation results of cycle time are more accurate and closer to reality. An A-BPSO algorithm is proposed to improve the stability and convergence in dealing with the problems with higher dimensional search space. This research can be used by the project managers and dispatchers on assembly field.

This paper aims to investigate the cell layout problem of aircraft assembly system. A mathematical model for this problem is proposed, taking into account the integration design of cell layout and logistics network. The means of logistics transportation are divided into horizontal transportation and space transportation, meanwhile, the logistics transportation route is calculated. Based on sequence pair, the presentation of solution structure for cell layout is put forward, and the solution structure is solved using simulated annealing algorithm. This method is applied successfully to the assembly cell layout of the fuselage-wing assembly system for a giant aircraft, and the result shows its feasibility and effectiveness.
