Determination of the most appropriate method for extrapolating overall survival data from a placebo-controlled clinical trial of lenvatinib for progressive, radioiodine-refractory differentiated thyroid cancer
Background: Cost-effectiveness models for the treatment of long-term conditions often require information on survival beyond the period of available data.
Objectives: This paper aims to identify a robust and reliable method for the extrapolation of overall survival (OS) in patients with radioiodine-refractory differentiated thyroid cancer receiving lenvatinib or placebo.
Methods: Data from 392 patients (lenvatinib: 261, placebo: 131) from the SELECT trial are used over a 34-month period of follow-up. A previously published criterion-based approach is employed to ascertain credible estimates of OS beyond the trial data. Parametric models with and without a treatment covariate and piecewise models are used to extrapolate OS, and a holistic approach, where a series of statistical and visual tests are considered collectively, is taken in determining the most appropriate extrapolation model.
Results: A piecewise model, in which the KaplanâMeier survivor function is used over the trial period and an extrapolated tail is based on the Exponential distribution, is identified as the optimal model.
Conclusion: In the absence of long-term survival estimates from clinical trials, survival estimates often need to be extrapolated from the available data. The use of a systematic method based on a priori determined selection criteria provides a transparent approach and reduces the risk of bias. The extrapolated OS estimates will be used to investigate the potential long-term benefits of lenvatinib in the treatment of radioiodine-refractory differentiated thyroid cancer patients and populate future cost-effectiveness analyses
Breastfeeding or Formula Feeding: A Mother\u27s Choice
Deciding how to feed an infant is a decision that should be made by a mother and her family. The benefits of exclusively breastfeeding an infant for the first six months of life are well established (World Health Organization [WHO], 2017); however, it may not always be feasible or a preferred option. For mothers who cannot or choose not to breastfeed, formula feeding is a great option that can support a healthy and thriving infant. This fact sheet will address common questions about breastfeeding and formula feeding to help mothers make an informed decision on how to feed their infant, whether it is by breastfeeding, formula feeding, or a combination of the two
Development and evaluation of an educational training package to promote health and wellbeing
Background: Supporting the health and wellbeing of healthcare employees is a UK national priority.
Aims: To design, deliver and evaluate an educational package to promote health and wellbeing for nurses and midwives
Methods: An online training package was developed and administered in two ways: online (HAWN-online) or in a face-to-face workshop (HAWN-contact). A mixed- methods evaluation was used to assess usability and acceptability of HAWN training. Findings: 316 nurses, midwives and students completed the online training package. 16 participants attended the workshop. HAWN-online significantly increased knowledge in core areas of workplace health and wellbeing. Nurses and midwives valued online and face-to-face delivery but raised barriers to attendance at workshops. Participants advocated that training in workplace health should be mandatory for all frontline staff.
Conclusions: Employers should take steps to promote staff wellbeing through HAWN training, and address barriers to accessing workplace health training or supportive services
Concerns, coping and the electronic holistic needs assessment: experiences of UK breast cancer survivors
Background: Physical and psychological concerns associated with a breast cancer diagnosis continue long after treatment. Macmillan Cancer Support developed an electronic Holistic Needs Assessment (eHNA) to help identify these concerns and allow a healthcare professional to address these as part of The Recovery Package.Aims: The study aim was to understand the womenâs experiences of having breast cancer, and of completing Macmillanâs eHNA as part of their care.Methods: A qualitative approach was adopted. Semi-structured interviews were undertaken with fifteen women, 12-18 months following surgical treatment for invasive breast cancer. Thematic analysis identified key themes.Results: Four main themes were identified in relation to: experiences of the eHNA, experiences of breast cancer, coping with breast cancer and the psychological effects of surviving. Perceptions towards the eHNA varied; some women viewed the eHNA as a research tool for hospital use rather than a beneficial aspect of their care. Several participants felt unable to raise their psychological concerns on the eHNA.Conclusions: Although experiences differ, psychological issues remain a key factor for women with breast cancer, lasting long after treatment. The eHNA is not currently used to its potential, or recognised by women as a tool to support their care. Further research is needed into how the eHNA can be used effectively to capture psychological concerns and determine best approaches to implementation of the tool to support individualised care
Machine learning forecasting for COVID-19 pandemic-associated effects on paediatric respiratory infections
OBJECTIVE: The COVID-19 pandemic and subsequent government restrictions have had a major impact on healthcare services and disease transmission, particularly those associated with acute respiratory infection. This study examined non-identifiable routine electronic patient record data from a specialist children's hospital in England, UK, examining the effect of pandemic mitigation measures on seasonal respiratory infection rates compared with forecasts based on open-source, transferable machine learning models. METHODS: We performed a retrospective longitudinal study of respiratory disorder diagnoses between January 2010 and February 2022. All diagnoses were extracted from routine healthcare activity data and diagnosis rates were calculated for several diagnosis groups. To study changes in diagnoses, seasonal forecast models were fit to prerestriction period data and extrapolated. RESULTS: Based on 144â704 diagnoses from 31â002 patients, all but two diagnosis groups saw a marked reduction in diagnosis rates during restrictions. We observed 91%, 89%, 72% and 63% reductions in peak diagnoses of 'respiratory syncytial virus', 'influenza', 'acute nasopharyngitis' and 'acute bronchiolitis', respectively. The machine learning predictive model calculated that total diagnoses were reduced by up to 73% (z-score: -26) versus expected during restrictions and increased by up to 27% (z-score: 8) postrestrictions. CONCLUSIONS: We demonstrate the association between COVID-19 related restrictions and significant reductions in paediatric seasonal respiratory infections. Moreover, while many infection rates have returned to expected levels postrestrictions, others remain supressed or followed atypical winter trends. This study further demonstrates the applicability and efficacy of routine electronic record data and cross-domain time-series forecasting to model, monitor, analyse and address clinically important issues
Impacts of the COVID-19 pandemic and self-isolation on students and staff in higher education: A qualitative study
This qualitative study explored the impact of COVID-19 self-isolation and social restriction measures on university students, through the perspectives of both students and the staff supporting them. The study comprised 11 focus groups (students) and 26 individual interviews (staff) at a higher education institution in England during a period of national lockdown (JanuaryâMarch 2021). Participants were university students (n = 52) with self-isolation experiences and university staff (n = 26) with student-facing support roles. Focus group and interview data were combined and analysed using an inductive thematic approach. Four themes emerged: âAdaptation during the pandemicâ, âPractical, environmental, and emotional challenges of self-isolatingâ, âSocial factors and their impact on COVID-19 testing and self-isolation adherenceâ, and âSupporting self-isolationâ. Students and staff struggled with the imposed restrictions and shift to online education. Students found it difficult to adapt to new expectations for university life and reported missing out on professional and social experiences. Students and staff noted concerns about the impact of online teaching on educational outcomes. Students endorsed varied emotional responses to self-isolation; some felt unaffected whilst others experienced lowered mood and loneliness. Students were motivated by pro-social attitudes; campaigns targeting these factors may encourage continued engagement in protective behaviours. Staff struggled to manage their increased workloads delivering support for self-isolating students. Universities must consider the support needs of students during self-isolation and prepare for the long-term impacts of the pandemic on student wellbeing and educational attainment. Greater support should be provided for staff during transitional periods, with ongoing monitoring of workforce stress levels warranted
INvestigational Vertebroplasty Efficacy and Safety Trial (INVEST): a randomized controlled trial of percutaneous vertebroplasty
Background: The treatment of painful osteoporotic vertebral compression fractures has historically been limited to several weeks of bed rest, anti-inflammatory and analgesic medications, calcitonin injections, or external bracing. Percutaneous vertebroplasty (the injection of bone cement into the fractured vertebral body) is a relatively new procedure used to treat these
fractures. There is increasing interest to examine the efficacy and safety of percutaneous vertebroplasty and to study the possibility of a placebo effect or whether the pain relief is from local anesthetics placed directly on the bone during the vertebroplasty procedure.
Methods/Designs: Our goal is to test the hypothesis that patients with painful osteoporotic vertebral compression fractures who undergo vertebroplasty have less disability and pain at 1 month than patients who undergo a control intervention. The control intervention is placement of local anesthesia near the fracture, without placement of cement. One hundred sixty-six patients with painful osteoporotic vertebral compression fractures will be recruited over 5 years from US and foreign sites
performing the vertebroplasty procedure. We will exclude patients with malignant tumor deposit (multiple myeloma), tumor
mass or tumor extension into the epidural space at the level of the fracture.
We will randomly assign participants to receive either vertebroplasty or the control intervention. Subjects will complete a battery of validated, standardized measures of pain, functional disability, and health related quality of life
at baseline and at post-randomization time points (days 1, 2, 3, and 14, and months 1, 3, 6, and 12). Both subjects and research interviewers performing the follow-up assessments will be blinded to the randomization assignment. Subjects will have a clinic visit at months 1 and 12. Spine X-rays will be obtained at the end of the study (month 12) to determine subsequent fracture rates. Our co-primary outcomes are the modified Roland score and pain numerical rating scale at 1 month.
Discussion: Although extensively utilized throughout North America for palliation of pain, vertebroplasty still has not
undergone rigorous study. The study outlined above represents the first randomized, controlled study that can account for a placebo effect in the setting of vertebroplasty.

Perceptions and Experiences of the University of Nottingham Pilot SARS-CoV-2 Asymptomatic Testing Service: A Mixed-Methods Study
© 2020 by the authors. Licensee MDPI, Basel, Switzerland. We aimed to explore student and staff perceptions and experiences of a pilot SARS-CoV-2 asymptomatic testing service (P-ATS) in a UK university campus setting. This was a mixed-method study comprised of an online survey, and thematic analysis of qualitative data from interviews and focus groups conducted at the mid-point and end of the 12-week P-ATS programme. Ninety-nine students (84.8% female, 70% first year; 93.9% P-ATS participants) completed an online survey, 41 individuals attended interviews or focus groups, including 31 students (21 first year; 10 final year) and 10 staff. All types of testing and logistics were highly acceptable (virus: swab, saliva; antibody: finger prick) and 94.9% would participate again. Reported adherence to weekly virus testing was high (92.4% completed â„6 tests; 70.8% submitted all 10 swabs; 89.2% completed â„1 saliva sample) and 76.9% submitted â„3 blood samples. Students tested to âkeep campus safeâ, âcontribute to national efforts to control COVID-19â, and âprotect othersâ. In total, 31.3% had high anxiety as measured by the Generalized Anxiety Disorder scale (GAD-7) (27.1% of first year). Students with lower levels of anxiety and greater satisfaction with university communications around P-ATS were more likely to adhere to virus and antibody tests. Increased adherence to testing was associated with higher perceived risk of COVID-19 to self and others. Qualitative findings revealed 5 themes and 13 sub-themes: âemotional responses to COVID-19â, âuniversity life during COVID-19â, âinfluences on testing participationâ, âtesting physical and logistical factorsâ and âtesting effects on mental wellbeingâ. Asymptomatic COVID-19 testing (SARS-CoV-2 virus/antibodies) is highly acceptable to students and staff in a university campus setting. Clear communications and strategies to reduce anxiety are likely to be important for testing uptake and adherence. Strategies are needed to facilitate social connections and mitigate the mental health impacts of COVID-19 and self-isolation
