Abstract

Purpose

Most of the current radiation treatment planning systems use pre‐treatment computed tomography (CT) images to detect the tumor location and then plan the radiation therapy to be delivered during the treatment period. It is assumed that the tumor geometry will not change throughout the treatment course; however, tumor geometry is shown to be changing over time. The purpose of this paper is to present results of an ongoing research in 3‐D modeling and reconstruction of head and neck cancer tumors. The results from this phase of the project will be used in developing a prediction model for tumor deformation during radiation treatment of cancer patients.

Design/methodology/approach

By using CT scan data in the 3‐D ASCII format, the tumor's progressive geometric changes during the treatment period are quantified. After constructing slice contours, both triangular and rectangular patch approaches are applied to map and analyze the tumor surface and volume. The changes in tumor location are calculated based on a reference feature on the top of the spine canal. MATLAB routines are developed to perform the required calculations. A set of prototype mockups of different stages are used for the purpose of validation and verification of the proposed methodology.

Findings

The proposed method is applied to calculate volume, surface, and displacement of the tumor, using patients’ data obtained from the University of Texas‐MD Anderson Cancer Center. The results are consistent with the actual data.

Originality/value

The proposed methodology increases the accuracy of treatment planning by predicting the changes in tumor geometry. The literature survey reveals that no work has been devoted to mathematically model the geometrical changes that a tumor might go through after each radiation.

Abstract

Purpose

Work-based placements are central to the university education of allied health and social work (AHSW) students. As a result of COVID-19, the clinical learning environment of students' work-based placements was dramatically altered resulting in numerous documented challenges. This inter-disciplinary study aimed to evaluate AHSW students' perceptions and experiences of completing a diverse range of work-based placements during COVID-19.

Design/methodology/approach

This study was a mixed-method inter-disciplinary study using an anonymous online survey consisting of multiple choice, Likert scale and free text questions. Mixed-methods design supported amalgamation of insights from positivism and interpretivism perspectives and enabled research questions to be answered with both breadth and depth. 436 students were invited to participate who were enrolled in five AHSW educational university programmes: speech and language therapy, occupational therapy, physiotherapy, radiation therapy and social work. Data collected was analysed using both quantitative (descriptive and analytical statistics) and qualitative (thematic analysis) methods.

Findings

118 students participated (response rate: 27%) representing a range of AHSW disciplines who attended diverse placement settings. While there was extensive disruption in the learning environment leading to increased levels of stress and concern, a triad of individual and systemic supports helped to ensure positive work-based placement experiences and student success for the majority of AHSW students during COVID-19: (1) university preparation and communication; (2) placement site and supervisor support; and (3) students' resilience and capacity to adapt to a changed work-place environment.

Originality/value

This inter-disciplinary study reports the work-based placement experiences from the professional education programmes of healthcare students during the COVID-19 pandemic, giving a unique view of their perspectives and learning during this unprecedented crisis.

Abstract

This brief chapter explores my experiences with music and death throughout my cancer treatment. Though I constantly confronted my mortality throughout my cancer treatment, music also helped to distract me from unpleasant, lengthy or boring treatments, as well as helping me to process my feelings about my own mortality. It thus served two distinct purposes, both focusing my mind on death and pain and distancing me from it.

Abstract

This is the third in a series of papers aimed at providing models effective in predicting the degree of pain and discomfort in canines. The first two papers provided benchmarking and examination of dogs suffering from osteoarthritis (OA). In this chapter, we extend the study to include dogs suffering from OA, sarcoma, and oral mucositis (a side effect of chemotherapy and radiation treatments). The R programming language and SAS JMP are used to clean data, generate ANOVA, LSR regression, decision tree, and nominal logistic regression models to predict changes in activity levels associated with the progression of arthritis. The predictive models provide a diagnostic basis for determining the degree of disease in a dog (based on demographics and activity levels) and provide forecasts that assist in establishing appropriate medication dosages for suffering dogs.

Abstract

The Abdur Razzaque Ansari Memorial Weavers Hospital (ARAM) came into effect on 7 April 1996, and is dedicated to the people of Jharkhand and weavers. To deal with the issues of inequity in healthcare services, ARAM was founded for the extension of affordable healthcare services to the needy in and around the area of Jharkhand. Visualised by a great social worker and legend Abdur Razzaque Ansari, it has been successfully run by his eldest son Mr Sayeed Ahmad Ansari for 28 years. This research uses mainly a case-study approach through secondary data from the hospital website and other websites citing ARAM and its functions. Consent to use data for the study was obtained from Mr. Sayeed Ahmad Ansari. Primary information was collected through the patients who availed facilities from the hospital. They were interviewed through a semi-structured questionnaire each taking 30-40 minutes. Taken over by Medanta Group on 8 July 2015 (earlier being managed by Apollo Hospitals Group for 20 years), it is the first super speciality community hospital in Eastern India. Treating over 50,000 patients yearly with state-of-the-art medical equipment and providing discounts to lower-income groups, people from the weaver’s community, freedom fighters and members of ICSI have intrigued people from these sections for affordable treatment and facilities in and near Jharkhand. With a 200 bed-capacity, nine different disciplines and 12 departments spread across the city of Ranchi, the hospital caters to a massive population at a much-subsidised rate. Reaching out to rural villages through free medical camps and awareness campaigns, the hospital showcases how a successful model of healthcare cooperative can be replicated accordingly in similar developing and underdeveloped regions.

Abstract

Purpose

The purpose of this paper is to evaluate the dosimetric properties of N-(3-methoxypropyl) acrylamide (NMPA) polymer gel dosimeter using UV-vis spectrophotometry as a simple and low-cost method.

Design/methodology/approach

The gel samples have been irradiated to various doses using a medical linear accelerator with 6 MV beam energy. The optical density of un-irradiated and irradiated NMPA polymer gel dosimeters in terms of absorbance at 500 nm was investigated by UV-vis spectrophotometry.

Findings

The absorbance values of the gel samples were increased linearly with increasing dose in the dose range between 2 and 20 Gy. A remarkable improvement in the dose response was noticed after the addition of various concentrations of glycerol. The impact of dose rate, beam energy and the post-stability of the exposed gels was studied and found consistent with the previous study using nuclear magnetic resonance results (energy independent and dose rate independent, stable up to one week).

Practical implications

The results of the independent experimental spectrophotometry and nuclear magnetic resonance analyses indicate that the NMPA polymer gel dosimeter has good and consistent dosimetric features for radiotherapy dosimetry.

Originality/value

The ionizing radiation-induced polymerization of gel samples leads to a change in the absorbance of the irradiated gel samples. This study introduces the first characterization of NMPA gel dosimeter by means of UV-vis spectrophotometer.

Abstract

Purpose

The purpose of this article is to highlight the importance of the foundational construct of “connection” in linking design and service in performing vital functions in the healthcare sector. “Connection” facilitates patients receiving life-saving and life-improving care at the right time, in the right place, in the right way.

Design/methodology/approach

This article discusses various design-improvement initiatives making clear that healthcare, like any labor-intensive service delivered to people, is a human endeavor whose systems and features can be materially and cleverly enhanced once their intricacies are analyzed, understood and then redesigned to move closer to excellence.

Findings

By designing connection into healthcare and thinking holistically about the needs and preferences of users (patients), the functionality and the appeal of healthcare services can be enhanced.

Originality/value

The gap between the service that healthcare aims to deliver – and what it actually delivers – is unacceptably large. This article calls for incorporating connection through design into healthcare as a way to bridge this gap.

Abstract

Purpose

Cancer care is complex and an integrated cancer pathway involves many health professionals in a variety of care settings using many skills. The widely distributed and heterogeneous nature of the cancer workforce raises significant challenges with respect to professional development. Cancer Learning is a government-funded initiative designed to provide access to a wide range of quality online learning resources for all health care professionals involved in the care of cancer patients and their families. The purpose of this paper is to discuss these issues.

Design/methodology/approach

A multi-phase project, led by a consortium of national stakeholders in cancer care, informed the design, build, and deployment of Cancer Learning; an online, evidence based, information and learning portal to support professional development of health professionals across the continuum of cancer care in Australia. An action research approach allowed for an iterative process of ongoing dynamic evaluation and improvement of this workforce improvement resource.

Findings

The National Government Agency, Cancer Australia's Cancer Learning online hub has been supporting the professional development requirements of cancer care professionals since the site deployment in 2007. Since launch, site usage continues to grow and evaluations have been positive. Time constraints of health professionals continue to be a major barrier to sustained online learning participation.

Originality/value

This research recount of the development and implementation of an Australia first national online learning initiative highlights the rigorous approach undertaken for the delivery of a quality evidence-based resource for the professional development of all health professionals involved in the delivery of cancer care.
