Abstract

Since FDS simulations of real fire scenarios are time-consuming, parametric studies are to be avoided, and it is worth investigating whether an alternative analytical model can predict the structural impact of the fire load with the same accuracy. This experimental study is designed to reflect the conditions of a tall building with a rather high steel structure level (starting at 11m) and low fire level (car fire at 1.5m). For this featured project, the difference is investigated between several car fires and the localised fire scenarios from annex C of EN 1991-1-2 (Heskestad model).

Abstract

Purpose

The study aims to summarise the literature on cancer care pathways at the diagnostic and treatment phases. The objectives are to find factors influencing the delivery of cancer care pathways; to highlight any interrelating factors; to find gaps in the literature concerning areas of research; to summarise the strategies and recommendations implemented in the studies.

Design/methodology/approach

The study used a qualitative approach and developed a causal loop diagram to summarise the current literature on cancer care pathways, from screening and diagnosis to treatment. A total of 46 papers was finally included in the analysis, which highlights the recurring themes in the literature.

Findings

The study highlights the myriad areas of research applied to cancer care pathways. Factors influencing the delivery of cancer care pathways were classified into different albeit interrelated themes. These include access barriers to care, hospital emergency admissions, fast track diagnostics, delay in diagnosis, waiting time to treatment and strategies to increase system efficiency.

Originality/value

As far as the authors know, this is the first study to present a visual representation of the complex relationship between factors influencing the delivery of cancer care pathways.

Abstract

Purpose

The development of new advanced materials, such as photopolymerizable resins for use in stereolithography (SLA) and Ti6Al4V manufacture via selective laser melting (SLM) processes, have gained significant attention in recent years. Their accuracy, multi-material capability and application in novel fields, such as implantology, biomedical, aviation and energy industries, underscore the growing importance of these materials. The purpose of this study is oriented toward the application of new advanced materials in stent manufacturing realized by 3D printing technologies.

Design/methodology/approach

The methodology for designing personalized medical devices, implies computed tomography (CT) or magnetic resonance (MR) techniques. By realizing segmentation, reverse engineering and deriving a 3D model of a blood vessel, a subsequent stent design is achieved. The tessellation process and 3D printing methods can then be used to produce these parts. In this context, the SLA technology, in close correlation with the new types of developed resins, has brought significant evolution, as demonstrated through the analyses that are realized in the research presented in this study. This study undertakes a comprehensive approach, establishing experimentally the characteristics of two new types of photopolymerizable resins (both undoped and doped with micro-ceramic powders), remarking their great accuracy for 3D modeling in die-casting techniques, especially in the production process of customized stents.

Findings

A series of analyses were conducted, including scanning electron microscopy, energy-dispersive X-ray spectroscopy, mapping and roughness tests. Additionally, the structural integrity and molecular bonding of these resins were assessed by Fourier-transform infrared spectroscopy–attenuated total reflectance analysis. The research also explored the possibilities of using metallic alloys for producing the stents, comparing the direct manufacturing methods of stents’ struts by SLM technology using Ti6Al4V with stent models made from photopolymerizable resins using SLA. Furthermore, computer-aided engineering (CAE) simulations for two different stent struts were carried out, providing insights into the potential of using these materials and methods for realizing the production of stents.

Originality/value

This study covers advancements in materials and additive manufacturing methods but also approaches the use of CAE analysis, introducing in this way novel elements to the domain of customized stent manufacturing. The emerging applications of these resins, along with metallic alloys and 3D printing technologies, have brought significant contributions to the biomedical domain, as emphasized in this study. This study concludes by highlighting the current challenges and future research directions in the use of photopolymerizable resins and biocompatible metallic alloys, while also emphasizing the integration of artificial intelligence in the design process of customized stents by taking into consideration the 3D printing technologies that are used for producing these stents.

Abstract

Purpose

Integrated health and social care initiatives are increasing and health and social care systems are aiming to improve health and social outcomes in disadvantaged groups. There is a global dialogue surrounding improving services by shifting to an integrated health and social care approach. There is consensus of what is “health care”; however, the “social care” definition remains less explored. The authors describe the state of “social care” within the current integrated care literature and identify the depth of integration in current health and social care initiatives.

Design/methodology/approach

A narrative literature review, searching Medline, PsychINFO, CINAHL, PubMed, Scopus and Cochrane databases and grey literature (from 2016 to 2021), employing a search strategy, was conducted.

Findings

In total. 276 studies were eligible for full-text review, and 33 studies were included and categorised in types: “social care as community outreach dialogues”, “social care as addressing an ageing population”, “social care as targeting multimorbidity and corresponding social risks factors” and “social care as initiatives addressing the fragmentation of services”. Most initiatives were implemented in the United Kingdom. In total, 21 studies reported expanding integrated governance and partnerships; 27 studies reported having health and social care staff with clear integrated governance; 17 had dedicated funding and 11 used data-sharing and the integration of systems’ records.

Originality/value

The authors' demonstrate that social care approaches are expanding beyond the elderly, and these models have been used to respond to multimorbidity [including coronavirus disease 2019 (COVID-19)], targeting priority groups and individuals with complex presentations.
