Introduction

Neoadjuvant therapy has become a standard treatment for patients with stage II/III HER2 positive and triple negative breast cancer, and in well-selected patients with locally advanced and borderline resectable high risk, luminal B breast cancer. Side effects of neoadjuvant therapy, such as fatigue, cardiotoxicity, neurotoxicity, anxiety, insomnia, vasomotor symptoms, gastrointestinal disturbance as well as a raft of immune-related adverse events, may impact treatment tolerance, long-term outcomes, and quality of life. Providing early supportive care prior to surgery (typically termed ‘prehabilitation’) may mitigate these side effects and improve quality of life.

During our codesign of the intervention, consumers and healthcare professionals expressed desire for a programme that ‘packaged’ care, was easy to access, and was embedded in their care pathway. We hypothesise that a multimodal supportive care programme including exercise and complementary therapies, underpinned by behavioural change theory will improve self-efficacy, quality of life, readiness for surgery and any additional treatment for women with breast cancer. We seek to explore cardiometabolic, residual cancer burden and surgical outcomes, along with chemotherapy completion (relative dose intensity). This article describes the protocol for a feasibility study of a multimodal prehabilitation programme.

Methods and analysis

This is a prospective, mixed-method, feasibility study of a multi-modal programme in a hospital setting for 20–30 women with breast cancer receiving neoadjuvant therapy. Primary outcomes are recruitment rate, retention rate, adherence and acceptability. Secondary outcomes include patient reported outcome measures (PROMs), surgical outcomes, length of stay, satisfaction with surgery, chemotherapy completion rates, changes in metabolic markers and adverse events. Interviews and focus groups to understand the experience with prehabilitation and different factors that may affect feasibility of the intervention . The output of this study will be a codesigned, evidence-informed intervention assessed for feasibility and acceptability by women with breast cancer and the healthcare professionals that care for them.

Ethics and dissemination

The study received ethics approval from the St Vincents Hospital HREC (HREC/2021/ETH12198). Trial results will be communicated to participants, healthcare professionals, and the public via publication and conferences.

INdigenous Systems and Policies Improved and Reimagined for Ear and hearing care (INSPIRE): a multi-method study protocol

Por: Nash · K. · Gwynne · K. · Dimitropoulos · Y. · Fitzpatrick · M. · Gunasekera · H. · Halvorsen · L. · Kong · K. · Lumby · N. · Macniven · R. · Parter · C. · Wingett · A. · McMahon · C.
Introduction

Otitis media (middle ear disease) severity and chronicity among Aboriginal and Torres Strait Islander people, as well as gaps in socioeconomic outcomes related to hearing loss, indicates a breakdown in the current ear and hearing care system. The ear and hearing care system spans multiple sectors due to long-term impacts of otitis media and hearing loss in health, education and employment, necessitating a multi-disciplinary cross-sectorial approach to ear and hearing care. Public policies shape the current ear and hearing care system and here it is argued that a critical public policy analysis across different sectors is needed, with strong Aboriginal and Torres Strait Islander leadership and guidance. The current study aims to establish consensus-based ear and hearing care policy solutions for Aboriginal and Torres Strait Islander people in Australia.

Methods and analysis

This multi-method study will be guided by a Brains Trust with strong Aboriginal and Torres Strait Islander leadership. Public policies in hearing health, social services, and education will be scoped to identify policy gaps, using the World Health Organization framework. Qualitative data will be collected through a culturally specific process of yarning circles to identify policy challenges and/or limitations in enabling accessible ear and hearing care programs/services for Aboriginal and Torres Strait Islander people, using dimensions of Morestin’s public policy appraisal tool as an interview guide for stakeholders. Themes from the yarning circles will be used to inform an expert Delphi process to establish consensus-based policy solutions for optimising the ear and hearing care system for Aboriginal and Torres Strait Islander people.

Ethics and dissemination

This study has approval from the Australian Institute of Aboriginal and Torres Strait Islander Studies Ethics Committee. Study findings will be disseminated to community through Brains Trust members and study participants, as well as through publications in peer-reviewed journals and research forum presentations.

Screening for antibacterial and cytotoxic activities of Sri Lankan marine sponges through microfractionation: Isolation of bromopyrrole alkaloids from <i>Stylissa massa</i>

by Lakmini Kosgahakumbura, Jayani Gamage, Luke P. Robertson, Taj Muhammad, Björn Hellman, Ulf Göransson, Prabath Jayasinghe, Chamari Hettiarachchi, Paco Cárdenas, Sunithi Gunasekera

Sri Lanka is a biodiversity hotspot and one of the richest geographical locations of marine sponges in the Indian ocean. However, the most extensive taxonomical study on Sri Lankan sponge biodiversity dates back ~100 years and only a limited number of studies have been conducted on sponge natural products. In the current study, 35 marine sponge specimens (collected from 16 sponge habitats around Sri Lanka) were identified, microfractionated and evaluated for antibacterial and anticancer assays. In total, 30 species were characterized, of which 19 species gave extracts with antibacterial and/or cytotoxic activities. Microfractionated organic extract of Aciculites orientalis gave the most potent antibacterial activity against Staphylococcus aureus and strongest lymphoma cell toxicity was exhibited by the organic extract of Acanthella sp. Guided by the molecular ion peaks in the bioactive fractions, large-scale extraction of Stylissa massa led to the isolation of three bromopyrrole alkaloids, sceptrin, hymenin and manzacidin A/C. Of these, sceptrin exhibited broad spectrum antibacterial activity against both Escherichia coli and S. aureus (MIC of 62.5 μM against both species). Based on natural product literature, seven promising species were identified as understudied. Their further exploration may lead to the discovery of structurally novel compounds.

Using Gaussian process for velocity reconstruction after coronary stenosis applicable in positron emission particle tracking: An <i>in-silico</i> study

by Hamed Keramati, Adelaide de Vecchi, Ronak Rajani, Steven A. Niederer

Accurate velocity reconstruction is essential for assessing coronary artery disease. We propose a Gaussian process method to reconstruct the velocity profile using the sparse data of the positron emission particle tracking (PEPT) in a biological environment, which allows the measurement of tracer particle velocity to infer fluid velocity fields. We investigated the influence of tracer particle quantity and detection time interval on flow reconstruction accuracy. Three models were used to represent different levels of stenosis and anatomical complexity: a narrowed straight tube, an idealized coronary bifurcation with stenosis, and patient-specific coronary arteries with a stenotic left circumflex artery. Computational fluid dynamics (CFD), particle tracking, and the Gaussian process of kriging were employed to simulate and reconstruct the pulsatile flow field. The study examined the error and uncertainty in velocity profile reconstruction after stenosis by comparing particle-derived flow velocity with the CFD solution. Using 600 particles (15 batches of 40 particles) released in the main coronary artery, the time-averaged error in velocity reconstruction ranged from 13.4% (no occlusion) to 161% (70% occlusion) in patient-specific anatomy. The error in maximum cross-sectional velocity at peak flow was consistently below 10% in all cases. PEPT and kriging tended to overestimate area-averaged velocity in higher occlusion cases but accurately predicted maximum cross-sectional velocity, particularly at peak flow. Kriging was shown to be useful to estimate the maximum velocity after the stenosis in the absence of negative near-wall velocity.

Por: Ratnasekera · N. · Fazelzad · R. · Bagnarol · R. · Cunha · V. · Zimmermann · C. · Lau · J.
Introduction

A head and neck cancer (HNC) diagnosis significantly impacts a patient’s quality of life (QOL). Palliative care potentially improves their QOL. We will conduct a scoping review to identify existing knowledge about palliative care interventions for patients with HNC.

Methods and analysis

This scoping review was designed in accordance with the JBI Manual for Evidence Synthesis: Scoping Reviews and will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Our eligibility criteria follow the Population, Intervention, Comparison or Control, Outcomes and Study characteristics framework. The population is adult patients with locally advanced, metastatic, unresectable and/or recurrent HNC. We include peer-reviewed journal articles and articles in the press, in English, reporting on palliative care interventions with at least two of the eight National Consensus Project on Clinical Practice Guidelines for Quality Palliative Care domains; studies with and without comparators will be included. The outcomes are patient QOL (primary) and symptom severity, patients’ satisfaction with care, patients’ mood, advance care planning and place of death (secondary). We developed a search strategy across ten databases, to be searched from the inception to 11 September 2023: Medline ALL (Medline and EPub Ahead of Print and In-Process, In-Data-Review & Other Non-Indexed Citations), Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Embase Classic+Embase, Emcare and PsycINFO all from the OvidSP platform; CINAHL from EBSCOhost, Scopus from Elsevier, Web of Science from Clarivate and Global Index Medicus from WHO. We will extract data using a piloted data form and analyse the data through descriptive statistics and thematic analysis.

Ethics and dissemination

Ethics approval is not needed for a scoping review. We will disseminate the findings to healthcare providers and policy-makers by publishing the results in a scientific journal.

Factors associated with uptake of human papillomavirus vaccination among adolescent girls in Mettu town, southwest Ethiopia: a school-based cross-sectional study

Por: Dawud · A. · Kera · A. M. · Bekele · D. · Hiko · D. · Zewdie · A.
Objective

This study was designed to assess the level of uptake of human papillomavirus (HPV) vaccination and its associated factors among school-age adolescent girls.

Design

School-based cross-sectional study.

Setting

High schools in Mettu town, southwest Ethiopia, from 5 February to 10 March 2022.

Participants

Data were collected using a pretested and structured questionnaire through face-to-face interviews with 667 adolescent girls selected via multistage random sampling. Data were entered into EpiData V.3.1 and exported to SPSS V.26 for analysis. Simple binary logistic regression was done, and variables with a p value less than 0.25 were entered into a multivariable logistic regression model; variables with a p value

Results

About half (48.6%) of adolescent girls aged 14–18 years had received the HPV vaccine. Being in the 16–18 years age group (adjusted OR 2.7, 95% CI 1.50 to 4.80), having good knowledge (2.14, 95% CI 1.29 to 3.52), having a positive attitude (5.86, 95% CI 3.51 to 9.76), and getting encouragement from healthcare workers (3.04, 95% CI 1.36 to 6.79), teachers (2.14, 95% CI 1.05 to 4.34) and parents (2.39, 95% CI 1.02 to 5.64) were significantly associated with vaccine uptake.

Conclusion

The uptake of HPV vaccination was low. Having good knowledge and positive attitude as well as encouragement from parents, healthcare workers and teachers were identified as factors associated with HPV vaccine uptake. Improving knowledge about HPV and involving teachers and parents in the immunisation campaign might help promote HPV vaccine uptake.

Systematic review of seroprevalence of SARS-CoV-2 antibodies and appraisal of evidence, prior to the widespread introduction of vaccine programmes in the WHO European Region, January-December 2020

Por: Vaughan · A. · Duffell · E. · Freidl · G. S. · Lemos · D. S. · Nardone · A. · Valenciano · M. · Subissi · L. · Bergeri · I. · K Broberg · E. · Penttinen · P. · Pebody · R. · Keramarou · M.
Objectives

Systematic review of SARS-CoV-2 seroprevalence studies undertaken in the WHO European Region to measure pre-existing and cumulative seropositivity prior to the roll out of vaccination programmes.

Design

A systematic review of the literature.

Data sources

We searched MEDLINE, EMBASE and the preprint servers MedRxiv and BioRxiv in the WHO ‘COVID-19 Global literature on coronavirus disease’ database using a predefined search strategy. Articles were supplemented with unpublished WHO-supported Unity-aligned seroprevalence studies and other studies reported directly to WHO Regional Office for Europe and European Centre for Disease Prevention and Control.

Eligibility criteria

Studies published before the widespread implementation of COVID-19 vaccination programmes in January 2021 among the general population and blood donors, at national and regional levels.

Data extraction and synthesis

At least two independent researchers extracted the eligible studies; a third researcher resolved any disagreements. Study risk of bias was assessed using a quality scoring system based on sample size, sampling and testing methodologies.

Results

In total, 111 studies from 26 countries published or conducted between 1 January 2020 and 31 December 2020 across the WHO European Region were included. A significant heterogeneity in implementation was noted across the studies, with a paucity of studies from the east of the Region. Sixty-four (58%) studies were assessed to be of medium to high risk of bias. Overall, SARS-CoV-2 seropositivity prior to widespread community circulation was very low. National seroprevalence estimates after circulation started ranged from 0% to 51.3% (median 2.2% (IQR 0.7–5.2%); n=124), while subnational estimates ranged from 0% to 52% (median 5.8% (IQR 2.3%–12%); n=101), with the highest estimates in areas following widespread local transmission.

Conclusions

The low levels of SARS-CoV-2 antibody in most populations prior to the start of vaccine programmes underlines the critical importance of targeted vaccination of priority groups at risk of severe disease, while maintaining reduced levels of transmission to minimise population morbidity and mortality.
