Serosurvey for Japanese encephalitis virus antibodies following an outbreak in an immunologically naïve population, Victoria, 2022: a cross-sectional study.

OBJECTIVES: To investigate the distribution and prevalence of Japanese encephalitis virus (JEV) antibody (as evidence of past infection) in northern Victoria following the 2022 Japanese encephalitis outbreak, seeking to identify groups of people at particular risk of infection; to investigate the distribution and prevalence of antibodies to two related flaviviruses, Murray Valley encephalitis virus (MVEV) and West Nile virus Kunjin subtype (KUNV). STUDY DESIGN: Cross-sectional serosurvey (part of a national JEV serosurveillance program). SETTING: Three northern Victorian local public health units (Ovens Murray, Goulburn Valley, Loddon Mallee), 8 August - 1 December 2022. PARTICIPANTS: People opportunistically recruited at pathology collection centres and by targeted recruitment through community outreach and advertisements. People vaccinated against or who had been diagnosed with Japanese encephalitis were ineligible for participation, as were those born in countries where JEV is endemic. MAIN OUTCOME MEASURES: Seroprevalence of JEV IgG antibody, overall and by selected factors of interest (occupations, water body exposure, recreational activities and locations, exposure to animals, protective measures). RESULTS: 813 participants were recruited (median age, 59 years [interquartile range, 42-69 years]; 496 female [61%]); 27 were JEV IgG-seropositive (3.3%; 95% confidence interval [CI], 2.2-4.8%) (median age, 73 years [interquartile range, 63-78 years]; 13 female [48%]); none were IgM-seropositive. JEV IgG-seropositive participants were identified at all recruitment locations, including those without identified cases of Japanese encephalitis. The only risk factors associated with JEV IgG-seropositivity were age (per year: prevalence odds ratio [POR], 1.07; 95% CI, 1.03-1.10) and exposure to feral pigs (POR, 21; 95% CI, 1.7-190). The seroprevalence of antibody to MVEV was 3.0% (95% CI, 1.9-4.5%; 23 of 760 participants), and of KUNV antibody 3.3% (95% CI, 2.1-4.8%; 25 of 761). CONCLUSIONS: People living in northern Victoria are vulnerable to future JEV infection, but few risk factors are consistently associated with infection. Additional prevention strategies, including expanding vaccine eligibility, may be required to protect people in this region from Japanese encephalitis.

New insights from modelling studies and molecular dynamics simulations of the DIS5-S6 extracellular linker of the skeletal muscle sodium channel NaV1.4.

In the CryoEM-structure of the hSkMNaV1.4 ion channel (PDB:6AGF), the 59-residue DIS5-S6 linker peptide was omitted due to absence of electron density. This peptide is intriguing - comprised of unique sequence and found only in mammalian skeletal muscle sodium ion channels. To probe potential physiological and evolutionary significance, we constructed an homology model of the complete hSkMNaV1.4 channel. Rather than a flexible random coil potentiating drift across the channel, the linker folds into a compact configuration through self-assembling secondary structural elements. Analogous sequences from 48 mammalian organisms show hypervariability with between 40% and 100% sequence similarity. To investigate structural implications, sequences from 14 representative organisms were additionally modelled. All showed highly conserved N-and C-terminal residues closely superimposed, suggesting a critical functional role. An optimally located asparagine residue within the conserved region was investigated for N-linked glycosylation and MD simulations carried out. Results suggest a complex glycan added at this site in the linker may form electrostatic interactions with the DIV voltage sensing domain and be mechanistically involved in channel gating. The relationship of unique sequence, compact configuration, potential glycosylation and MD simulations are discussed relative to SkMNaV1.4 structure and function.

A qualitative exploration of the barriers and facilitators affecting ethnic minority patient groups when accessing medicine review services: Perspectives of healthcare professionals.

INTRODUCTION: Healthcare inequalities and ethnicity are closely related. Evidence has demonstrated that patients from ethnic minority groups are more likely to report a long-term illness than their white counterparts; yet, in some cases, minority groups have reported poorer adherence to prescribed medicines and may be less likely to access medicine services. Knowledge of the barriers and facilitators that impact ethnic minority access to medicine services is required to ensure that services are fit for purpose to meet and support the needs of all. METHODS: Semistructured interviews with healthcare professionals were conducted between October and December 2020, using telephone and video call-based software. Perspectives on barriers and facilitators were discussed. Interviews were audio-recorded and transcribed verbatim. Reflexive thematic analysis enabled the development of themes. QSR NVivo (Version 12) facilitated data management. Ethical approval was obtained from the Newcastle University Faculty of Medical Sciences Ethics Committee. RESULTS: Eighteen healthcare professionals were interviewed across primary, secondary and tertiary care settings; their roles spanned medicine, pharmacy and dentistry. Three themes were developed from the data regarding the perceived barriers and facilitators affecting access to medicine services for ethnic minority patients. These centred around patient expectations of health services; appreciating cultural stigma and acceptance of certain health conditions; and individually addressing communication and language needs. CONCLUSION: This study provides much-needed evidence relating to the barriers and facilitators impacting minority ethnic communities when seeking medicine support. The results of this study have important implications for the delivery of person-centred care. Involving patients and practitioners in coproduction approaches could enable the design and delivery of culturally sensitive and accessible medicine services. PATIENT OR PUBLIC CONTRIBUTION: The Patient and Public Involvement and Engagement (PPIE) group at Newcastle University had extensive input in the design and concept of this study before the research was undertaken. Throughout the work, a patient champion (Harpreet Guraya) had input in the project by ensuring that the study was conducted, and the findings were reported, with cultural sensitivity.

'He or she maybe doesn't know there is such a thing as a review': A qualitative investigation exploring barriers and facilitators to accessing medication reviews from the perspective of people from ethnic minority communities.

INTRODUCTION: Regular reviews of medications, including prescription reviews and adherence reviews, are vital to support pharmacological effectiveness and optimize health outcomes for patients. Despite being more likely to report a long-term illness that requires medication when compared to their white counterparts, individuals from ethnic minority communities are less likely to engage with regular medication reviews, with inequalities negatively affecting their access. It is important to understand what barriers may exist that impact the access of those from ethnic minority communities and to identify measures that may act to facilitate improved service accessibility for these groups. METHODS: Semi-structured interviews were conducted between June and August 2021 using the following formats as permitted by governmental COVID-19 restrictions: in person, over the telephone or via video call. Perspectives on service accessibility and any associated barriers and facilitators were discussed. Interviews were audio-recorded and transcribed verbatim. Reflexive thematic analysis enabled the development of themes. QSR NVivo (Version 12) facilitated data management. Ethical approval was obtained from the Health Research Authority (ref: 21/HRA/1426). RESULTS: In total 20 participants from ethnic minority communities were interviewed; these participants included 16 UK citizens, 2 refugees and 2 asylum seekers, and represented a total of 5 different ethnic groups. Three themes were developed from the data regarding the perceived barriers and facilitators affecting access to medication reviews and identified approaches to improve the accessibility of such services for ethnic minority patients. These centred on (1) building knowledge and understanding about medication reviews; (2) delivering medication review services; and (3) appreciating the lived experience of patients. CONCLUSION: The results of this study have important implications for addressing inequalities that affect ethnic minority communities. Involving patients and practitioners to work collaboratively in coproduction approaches could enable better design, implementation and delivery of accessible medication review services that are culturally competent. PATIENT OR PUBLIC CONTRIBUTION: The National Institute for Health Research Applied Research Collaboration and Patient and Public Involvement and Engagement group at Newcastle University supported the study design and conceptualization. Seven patient champions inputted to ensure that the research was conducted, and the findings were reported, with cultural sensitivity.

Recommendations for community pharmacy to improve access to medication advice for people from ethnic minority communities: A qualitative person-centred codesign study.

INTRODUCTION: Medicines-centred consultations are vital to support medicine effectiveness and optimize health outcomes for patients. However, inequalities negatively impact ethnic minority populations when accessing medicines advice. It is important to identify opportunities to improve access for these communities however, knowledge of how best to achieve this is lacking; this study will generate recommendations to improve access to medicines advice from community pharmacies for people from ethnic minority communities. METHODS: A series of codesign workshops, with four groups of patient-stakeholders, were conducted between September-November 2021; they took place in-person or via video call (adhering to COVID-19 restrictions). Existing evidence-based perceptions affecting access to medicines advice were critiqued and recommendations were generated, by use of reflexive thematic analysis, to improve access for ethnic minority patients. The workshops were audio-recorded and transcribed verbatim. QSR NVivo (Version 12) facilitated data analysis. RESULTS: Twelve participants were recruited using purposive sampling; including eight UK citizens, two asylum seekers and two participants in receipt of residency visas. In total, four different ethnic minority groups were represented. Each participant took part in a first and second workshop to share and cocreate recommendations to improve access to medicines advice in community pharmacies. Three recommendations were developed and centred on: (i) delivering and providing culturally competent medicines advice; (ii) building awareness of accessing medicines advice from community pharmacies; and (iii) enabling better discussions with patients from ethnic minority communities. CONCLUSIONS: These recommendations have the potential to support community pharmacy services to overcome ethnic inequalities affecting medicines advice; service commissioners should consider these findings to best meet the needs of ethnic minority patients. Cultural competence training for community pharmacy staff could support the creation of pharmacies as inclusive healthcare settings. Collaborative working with ethnic minority communities could enable specific tailoring of medicines-centred services to best meet their needs. PATIENT OR PUBLIC CONTRIBUTION: The National Institute for Health Research (NIHR) and Newcastle University Patient and Public Involvement and Engagement group had extensive input in the study design and conceptualization. Seven patient champions were appointed to the steering group to ensure that the research was conducted, and findings were reported, with cultural competence. TRIAL REGISTRATION: Not applicable.

Demographic and psychological predictors of community pharmacists' cancer-related conversations with patients: a cross-sectional analysis and survey study.

BACKGROUND: There is increasing interest in the role of community pharmacy in the early diagnosis and prevention of cancer. This study set out to examine how often community pharmacists (CPs) encourage patients to spot or respond to potential signs and symptoms of cancer, and how often they help people to make an informed decision about taking part in bowel cancer screening. METHODS: Data from 400 UK CPs, who completed the 2018 Cancer Research UK Healthcare Professional Tracker survey, were analysed. The primary outcomes were: 'how often CPs encourage patients to spot or respond to potential signs and symptoms of cancer' and 'how often CPs encourage eligible people to make an informed decision to participate in bowel cancer screening'. Associations between behaviours and demographic and psychological variables (Capability, Opportunity and Motivation) were assessed using multivariate logistic regression. RESULTS: Most (n = 331, 82.8%) CPs reported occasionally, frequently or always encouraging patients to spot or respond to potential signs and symptoms of cancer, while only half (n = 203, 50.8%) reported occasionally, frequently or always helping people make an informed decision to participate in bowel cancer screening. Female sex (aOR: 3.20, 95%CI: 1.51, 6.81; p < 0.01) and increased Opportunity (aOR: 1.72, 95%CIs: 1.12, 2.64; p < 0.05) and Motivation (aOR: 1.76, 95%CIs: 1.37, 2.27; p < 0.001) were associated with encouraging patients to spot or respond to potential signs and symptoms of cancer; all three psychological variables were associated with helping people to make an informed decision to participate in bowel cancer screening (Capability: aOR: 1.39, 95%CIs: 1.26, 1.52, p < 0.001; Opportunity: aOR: 1.44, 95%CIs: 1.11, 1.87; p < 0.01; Motivation: aOR: 1.45, 95%CIs: 1.05, 2.00; p < 0.05). CONCLUSIONS: Most CPs encourage patients to spot or respond to potential cancer symptoms, while only half help them make an informed decision to participate in bowel cancer screening. A multifaceted approach, targeting multiple COM-B components, is required to change these behaviours.

Family carers' experiences of dysphagia after a stroke: An exploratory study of spouses living in a large metropolitan city.

BACKGROUND: People with post-stroke dysphagia often require informal care from family to facilitate safe swallowing, modify food/drink or administer tube-feeds. Previous survey studies have found dysphagia may increase family caregiver burden. However, the experiences of family members in this population have not been fully explored. AIMS: To explore family members' experiences of living with a spouse with post-stroke dysphagia. METHODS & PROCEDURES: This exploratory qualitative study used one-to-one semi-structured interviews to explore family members' experiences. They were asked open questions about previous eating routines, dysphagia onset, their role and future hopes. Interviews were audio-recorded, transcribed and analysed thematically with an inductive approach to determine key features of family members' experiences. OUTCOMES & RESULTS: Five spouses aged 70-93 years participated. Their relatives' strokes happened 3 months to 3 years before the interview. Five themes were identified: 'I do all of it'; making sense of dysphagia; emotional responses; reflecting on relationships; and redefining lifestyle. CONCLUSIONS & IMPLICATIONS: It is important to consider family members' perspectives as they often provide vital care to loved-ones with dysphagia. In relation to eating and drinking, maintaining elements of previous routines seems important to families. Healthcare professionals should consider these when making recommendations for rehabilitation. Family members have differing perspectives of the comparative impact of dysphagia; patient and family priorities should be explored for healthcare professionals to provide better-targeted support. WHAT THIS PAPER ADDS: What is already known on the subject Informal caregivers, often spouses, play a vital role in supporting the health and well-being of older people with health conditions. The presence of post-stroke dysphagia may present increased challenges for the informal caregiver. There are limited studies qualitatively exploring the experiences of informal caregivers in this population. What this paper adds to existing knowledge Current health and social care provision for this population leaves informal caregivers feeling they have been left to manage dysphagia alone. Informal caregivers demonstrate a breadth of knowledge about their spouse's dysphagia, problem-solving effective solutions. Informal caregivers have a range of interpretations of the nature and cause of dysphagia; leading to miscommunication with health professionals and complex emotional responses. What are the potential or actual clinical implications of this work? Healthcare professionals might consider ways in which to support dysphagic patients' families later in their care pathway, through scheduling reviews or running dysphagia patient and family groups. Health and social care professionals and policymakers should learn from informal caregivers' expertise to promote better health and quality-of-life outcomes for the patient and caregiver. Equal, open conversations between health and social care professionals and patients/families on their understanding of dysphagia may help informal caregivers to better voice their concerns and support mutual understanding. This has implications for adherence to recommendations, psychological well-being and patient safety.

Designing the Optimal Digital Health Intervention for Patients' Use Before and After Elective Orthopedic Surgery: Qualitative Study.

BACKGROUND: Health behavior changes made by patients during the perioperative period can impact the outcomes and success of elective surgeries. However, there remains a limited understanding of how best to support patients during this time, particularly through the use of digital health interventions. Recognizing and understanding the potential unmet needs of elective orthopedic surgery patients is central to motivating healthier behavior change, improving recovery, and optimizing overall surgical success in the short and long term. OBJECTIVE: The aim of this study is to explore patient perspectives on technology features that would help support them to change their lifestyle behaviors during the pre- and postoperative periods, and that could potentially maintain long-term healthy lifestyles following recovery. METHODS: Semistructured interviews with pre- and postoperative elective orthopedic patients were conducted between May and June 2020 using telephone and video call-based software. Patient perspectives on the use of digital technologies to complement current surgical care and support with lifestyle behavior changes were discussed. Interviews were audio recorded and transcribed verbatim. Reflexive thematic analysis enabled the development of themes from the data, with QSR NVivo software (version 12) facilitating data management. Ethical approval was obtained from the National Health Service Health Research Authority. RESULTS: A total of 18 participants were interviewed. Four themes were developed from the data regarding the design and functionality of digital technologies to best support the perioperative journey. These center around an intervention's ability to incorporate interactive, user-centered features; direct a descriptive and structured recovery; enable customizable, patient-controlled settings; and deliver both general and specific surgical advice in a timely manner. Interventions that are initiated preoperatively and continued postoperatively were perceived as beneficial. Interventions designed with personalized milestones were found to better guide patients through a structured recovery. Individualized tailoring of preparatory and recovery information was desired by patients with previously high levels of physical activity before surgery. The use of personalized progression-based exercises further encouraged physical recovery; game-like rewards and incentives were regarded as motivational for making and sustaining health behavior change. In-built video calling and messaging features offered connectivity with peers and clinicians for supported care delivery. CONCLUSIONS: Specific intervention design and functionality features can provide better, structured support for elective orthopedic patients across the entire surgical journey and beyond. This study provides much-needed evidence relating to the optimal design and timing of digital interventions for elective orthopedic surgical patients. Findings from this study suggest a desire for personalized perioperative care, in turn, supporting patients to make health behavior changes to optimize surgical success. These findings should be used to influence future co-design projects to enable the design and implementation of patient-focused, tailored, and targeted digital health technologies within modern health care settings.

Prospective evaluation of the Whitt Neonatal Trigger Score in an 'at-risk' neonatal population.

AIM: The aim of this study was to prospectively evaluate the Whitt Neonatal Trigger Score (W-NTS), determining optimum threshold scores for consideration of medical intervention and intensive care unit admission. METHODS: All neonates on the postnatal ward (PNW) with a set of pre-defined risk factors were scored on the W-NTS. Neonates were divided into three groups: 'unwell' admitted to neonatal intensive care unit (NICU); 'well', who remained on the PNW receiving standard care; and 'intervention', who received antibiotics but did not require admission to NICU. RESULTS: A total of 3315 scores from 455 neonates were collected. The W-NTS area under the receiver operating characteristic curve (AUC ROC) was 0.968, with a score of 2 or more predicting NICU admission, with 82.5% sensitivity and 95.0% specificity. Adopting a cut-off score of 2 for admission would significantly improve speed to admission (11.6 vs. 6.9 h, P 0.037). A score of 0 was strongly predictive of being well enough to remain on the PNW without intervention (odds ratio 565.6, P < 0.001), and a score of 1 or more predicted the need for intravenous antibiotics with 100.0% sensitivity and 86.1% specificity (AUC ROC 0.977). CONCLUSION: The W-NTS observation chart, previously shown to outperform existing early warning scores, acts well as an adjunct to clinical assessment on the PNW, with its simplicity allowing for the successful and safe use by non-paediatric specialists. We recommend that neonates scoring 1 should be reviewed, with a septic screen and commencement of antibiotic therapy considered, while those scoring 2 or more should be strongly considered for NICU admission for further management.

An outbreak of gastroenteritis linked to a buffet lunch served at a Canberra restaurant.

In 2013, an outbreak of gastrointestinal illness occurred following a buffet lunch at a restaurant in Canberra. An investigation was conducted to identify the cause of illness and to implement appropriate public health measures to prevent further disease. We conducted a retrospective cohort study via telephone interviews, using a structured questionnaire developed from the restaurant buffet menu. A case was defined as someone who ate the buffet lunch at the restaurant on the implicated date and developed any symptoms of gastrointestinal illness (such as diarrhoea, abdominal pain and nausea) following the consumption of food. A total of 74% (225/303) of known attendees were interviewed, of whom 56% (125/225) had become ill. The median incubation period and duration of illness were 13 and 19 hours respectively. The most commonly reported symptoms were diarrhoea (94%, 118/125) and abdominal pain (82%, 103/125). A toxin-mediated gastrointestinal illness was suspected based on the incubation period, duration of illness and the symptoms. The environmental health investigation identified a lack of designated hand washing facilities in the kitchen, an absence of thermometers for measuring food temperatures and several maintenance and minor cleaning issues. A number of food samples were taken for microbiological analysis. Multivariable analysis showed that illness was significantly associated with consuming curried prawns (OR 18.4, 95% CI 8.6-39.3, P < 0.001) and Caesar salad (OR 3.6, 95% CI 1.8-7.5, P 0.001). Enterotoxin-producing Staphylococcus aureus and Bacillus cereus were identified in leftover samples of cooked buffet food, but this food was not epidemiologically implicated. The investigation suggested that a breakdown in cleanliness, temperature control and food handling practices may have resulted in contamination of the buffet food. In order to prevent such outbreaks in the future, caterers and restaurateurs need to ensure they have the appropriate facilities and procedures in place if planning to cater for large groups.

Evaluation of Nurse-Driven Management of Hypoglycemia In Critically Ill Patients.

BACKGROUND: Intensive care unit (ICU) patients experience hypoglycemia at nearly 4 times the rate seen in non-ICU counterparts. Although inpatient hypoglycemia management relies on nurse-driven protocols, protocol adherence varies between institutions and units. OBJECTIVE: To compare hypoglycemia management between ICU and non-ICU patients in an institution with high adherence to a hypoglycemia protocol. METHODS: This secondary analysis used retrospective medical record data. Cases were ICU patients aged 18 years or older with at least 1 hypoglycemic event (blood glucose level < 70 mg/dL); non-ICU controls were matched by age within 10 years, sex, and comorbidities. Time from initial hypoglycemic blood glucose level to subsequent blood glucose recheck, number of interventions, time to normoglycemia, and number of spontaneous hypoglycemic events were compared between groups. RESULTS: The sample included 140 ICU patients and 280 non-ICU controls. Median time to blood glucose recheck did not differ significantly between groups (19 minutes for both groups). Difference in mean number of interventions before normoglycemia was statistically but not clinically significant (ICU, 1.12; non-ICU, 1.35; P < .001). Eighty-four percent of ICU patients and 86% of non-ICU patients returned to normoglycemia within 1 hour. Median time to normoglycemia was lower in ICU patients than non-ICU patients (21.5 vs 26 minutes; P = .01). About 25% of patients in both groups experienced a spontaneous hypoglycemic event. CONCLUSION: Adherence to nurse-driven hypoglycemia protocols can be equally effective in ICU and non-ICU patients. Further research is needed to determine protocol adherence barriers and patient characteristics that influence response to hypoglycemia interventions.

The effect of COVID-19 public health measures on nationally notifiable diseases in Australia during 2020 and 2021.

Abstract: The novel coronavirus disease 2019 (COVID-19) pandemic prompted Australia to implement large-scale domestic lockdowns and halted international travel. However, the impact of these measures on national notifiable diseases is yet to been fully examined. In this paper, we expand on a preliminary analysis conducted in 2020, and conducted a retrospective, observational study using nationally notifiable disease surveillance system (NNDSS) data to examine if the changes identified in the first half of 2020 continued in Australia through wide-scale public health measures. We found that there was an overall reduction in most of Australia's nationally notifiable diseases over the two pandemic years during which wide-scale public health measures remained in operation, particularly for 23 social and imported diseases. We observed an increase in notifications for psittacosis, leptospirosis and legionellosis during these years. The public health measures implemented in 2020 and 2021 (including lockdowns, mask mandates, and increased hand and respiratory hygiene) may have contributed to the observed notification reductions. The outcomes of these measures' implementation provide insights into broader communicable disease control for mass outbreaks and pandemic responses.

Tuberculosis in elderly Australians: a 10-year retrospective review.

Objective: This report describes the epidemiology of active tuberculosis (TB) in elderly Australians (≥ 65 years) with analysis of the factors associated with TB disease and successful treatment outcomes. Methods: A retrospective study of TB cases reported to the National Notifiable Diseases Surveillance System over a 10-year period from 2011 to 2020 was conducted. Cases were stratified by sex, age, risk factors, drug resistance, treatment type and outcome. Notification rates and incidence rate ratios with 95% confidence intervals were calculated and factors associated with treatment success analysed using multivariable logistic regression. Results: A total of 2231 TB cases among elderly people were reported over the study period, with a 10-year mean incidence rate of 6.2 per 100 000 population. The median age of cases was 75 years (range 65-100 years); most were male (65%) and born overseas (85%). Multivariable analysis found that successful treatment outcome was strongly associated with younger age, while unsuccessful treatment outcome was associated with being diagnosed within the first 2 years of arrival in Australia, ever having resided in an aged-care facility and resistance to fluoroquinolones. Discussion: Compared to other low-incidence settings in the Western Pacific Region, TB incidence in elderly people is low and stable in Australia, with most cases occurring among recent migrants from TB-endemic settings. Continued efforts to reduce TB importation and address migrant health, especially among elderly people, are important.

Contextual factors influencing medicines-related interventions to support safe transitions for care home residents post hospital discharge: a systematic review and meta-ethnographic synthesis.

BACKGROUND: Residents of care or nursing homes are at a higher risk of medication-related harm, especially during care transitions. No medicines-related intervention has been identified that supports the safe transition for these residents moving into their residence following hospital discharge. A model of care integrating a number of intervention components is suggested to be most effective AIM: To investigate, via a systematic review and meta-ethnography, the factors which influence the impact of medicines related interventions. METHOD: In December 2020, Pubmed, MEDLINE, EMBASE, PsycINFO, and CINAHL Complete were systematically searched. All studies reporting on medicines-related interventions for residents following hospital discharge were included. Quality assessment was undertaken with a validated tool. Meta-ethnography was used to investigate the factors which influenced how interventions did, or did not work. Findings were mapped to a validated conceptual framework for integrated care. RESULTS: From 3884 studies, nine met the inclusion criteria and were analysed. These were generally of medium quality (n = 6). The interventions were diverse: some tackled the transition process, some tackled follow-up care and some interventions involved both. The meta-ethnography, using the a priori conceptual framework, captured factors reported within the studies that influenced implementation, delivery and/or outcomes. CONCLUSION: The review and synthesis informed the development of a conceptual model for transitionary care for this population group. Researchers and decision-makers can use this as a tool to understand their local context and inform future intervention design, implementation and evaluation in this clinical area.

The impact of the National Shingles Vaccination Program on the epidemiology of herpes zoster among adults ≥ 60 years in Victoria, Australia.

Introduction: In November 2016, Australia recommended herpes zoster (HZ) vaccination for adults aged ≥ 60 years and implemented a National Shingles Vaccination Program (NSVP) offering free HZ vaccination to adults aged 70-79 years. This study investigated trends in HZ epidemiology among Victorian adults aged ≥ 60 years and the impact of the NSVP in this population. Methods: We conducted epidemiological analyses of routinely collected HZ surveillance data for Victorian adults aged ≥ 60 years who were notified as having a HZ illness or vaccination between 2012 and 2021. Annual incidence rates are presented for vaccinations, case notifications, emergency department presentations, hospitalisations and deaths by five-year age groups. Age-specific incidence rate ratios are calculated comparing the period prior to (1 January 2012 to 31 October 2016) and following (1 November 2016 to 31 December 2021) NSVP implementation. Results: HZ vaccination rates were highest among those eligible to receive free vaccination (70-79 years), but appear to have plateaued across all age groups and remained below full coverage. Incidence rate ratios showed a statistically significant increase (p < 0.01) in HZ notifications across all age-groups. Emergency presentations and hospitalisations showed a statistically significant decline (p < 0.05) among the 70-79 year old age groups; however, these rates remained consistent or increased among other age groups for whom vaccination is recommended. Mortality rates declined, particularly among those aged 85+ years. Discussion: HZ continues to cause significant disease among the older adult population in Victoria. The findings of this study suggest the NSVP has led to some changes in the epidemiology of HZ among the 70-79 years old age group in Victoria; however, there is less evidence that it has influenced other age groups for whom vaccination is recommended. An evaluation of the NSVP and epidemiology of HZ at a national level is required to identify strategies to improve vaccination coverage among the target populations.

Lessons from the re-emergence of imported measles cases following the COVID-19 pandemic in Victoria, Australia.

Introduction: Australia was declared to have eliminated endemic measles in 2014; however, imported cases continue to pose a threat of outbreaks. International travel restrictions during the coronavirus disease 2019 (COVID-19) pandemic led to a rapid decline in measles cases. The re-opening of the Australian international border to measles endemic regions returns the threat of outbreaks, which may be further compounded by disruptions in routine vaccinations during the COVID-19 pandemic. We consider lessons learned from the public health response to recent measles cases. Methods: This case series includes all confirmed measles cases meeting the national case definition reported to the Victorian Government Department of Health (the Department) between 1 January and 31 December 2022. The Department conducted active case finding and contact tracing of all cases in line with national guidelines. Cases were descriptively analysed. Results: In 2022, six of the seven measles cases reported in Australia occurred in Victoria, all of whom resided in Australia and acquired their infection overseas. Three cases were unlinked, and three formed an epidemiologically-linked household cluster. One case was partially vaccinated, one was not eligible for vaccination, one had unknown vaccination status, and three were unvaccinated, one of whom was under 12 months old but would have been eligible for vaccination prior to travel to endemic regions. None of the cases led to secondary transmission within Australia. Discussion: Following the COVID-19 pandemic, measles importations have re-commenced in Victoria. Although few measles cases occurred in 2022 and none resulted in onwards transmission, imported measles cases remain complex and require substantial public health follow-up. Delays in case diagnosis and flight contact tracing pose a significant risk for outbreaks of measles. Public health interventions are needed to maintain high vaccination rates, improve contact tracing, and ensure public health authorities and healthcare providers can rapidly identify and respond to imported measles cases.

An outbreak of acute rheumatic fever in a remote Aboriginal community.

OBJECTIVES: We describe the public health response to an outbreak of acute rheumatic fever (ARF) in a remote Aboriginal community. METHODS: In August 2021, the Northern Territory Rheumatic Heart Disease Control Program identified an outbreak of acute rheumatic fever in a remote Aboriginal community. A public health response was developed using a modified acute poststreptococcal glomerulonephritis protocol and the National Acute Rheumatic Fever Guideline for Public Health Units. RESULTS: 12 cases were diagnosed during the outbreak; six-times the average number of cases in the same period in the five years prior (n=1.8). Half (n=6) of the outbreak cases were classified as recurrent episodes with overdue secondary prophylaxis. Contact tracing and screening of 11 households identified 86 close contacts. CONCLUSIONS: This outbreak represented an increase in both first episodes and recurrences of acute rheumatic fever and highlights the critical need for strengthened delivery of acute rheumatic fever secondary prophylaxis, and for improvements to the social determinants of health in the region. IMPLICATIONS FOR PUBLIC HEALTH: Outbreaks of acute rheumatic fever are rare despite continuing high rates of acute rheumatic fever experienced by remote Aboriginal communities. Nevertheless, there can be improvements in the current national public health guidance relating to acute rheumatic fever cluster and outbreak management.

Stereocontrolled asymmetric synthesis of syn-E-1,4-diol-2-enes using allyl boronates and its application in the total synthesis of solandelactone F.

The solandelactones A-H comprise a novel class of oxygenated fatty acids bearing an eight-membered lactone, trans cyclopropane, and a 2-ene-1,4-diol subunit. The relative stereochemistry of the 1,4-diol subunit is anti in solandelactones A, C, E & G, and syn in solandelactones B, D, F & H. Having prepared one member of the solandelactones bearing anti stereochemistry (solandelactone E), we have targeted the syn series and developed methodology for the synthesis of enantioenriched syn-2-ene-1,4-diols. The methodology comprises asymmetric deprotonation of an alkyl 2,4,6-triisopropylbenzoate using sBuLi/sparteine, followed by addition of the α-lithiobenzoate to ß-silyl vinyl boronic acid ethylene glycol ester. The boron-ate complex generated undergoes a 1,2-metallate rearrangement furnishing an intermediate allyl boronic ester which is trapped by an aldehyde in the presence of MgBr(2) to furnish anti-ß-hydroxy E-allylsilanes in good yields, high diastereoselectivity and high enantioselectivity. These sensitive products were oxidized using mCPBA to the corresponding epoxides and subsequently treated with acid to furnish syn-E-2-ene-1,4-diols (~4:1 d.r.). Application of the methodology to appropriately functionalized aldehyde and ω-alkenyl 2,4,6-triisopropylbenzoate coupling partners, led to a short, highly selective route to solandelactone F (bearing a syn-E-2-ene-1,4-diol).

Designing Digital Health Technology to Support Patients Before and After Bariatric Surgery: Qualitative Study Exploring Patient Desires, Suggestions, and Reflections to Support Lifestyle Behavior Change.

BACKGROUND: A patient's capability, motivation, and opportunity to change their lifestyle are determinants of successful outcomes following bariatric surgery. Lifestyle changes before and after surgery, including improved dietary intake and physical activity levels, have been associated with greater postsurgical weight loss and improved long-term health. Integrating patient-centered digital technologies within the bariatric surgical pathway could form part of an innovative strategy to promote and sustain healthier behaviors, and provide holistic patient support, to improve surgical success. Previous research focused on implementing digital technologies and measuring effectiveness in surgical cohorts. However, there is limited work concerning the desires, suggestions, and reflections of patients undergoing bariatric surgery. This qualitative investigation explores patients' perspectives on technology features that would support behavior changes during the pre- and postoperative periods, to potentially maintain long-term healthy lifestyles following surgery. OBJECTIVE: This study aims to understand how digital technologies can be used to support patient care during the perioperative journey to improve weight loss outcomes and surgical success, focusing on what patients want from digital technologies, how they want to use them, and when they would be of most benefit during their surgical journey. METHODS: Patients attending bariatric surgery clinics in one hospital in the North of England were invited to participate. Semistructured interviews were conducted with purposively sampled pre- and postoperative patients to discuss lifestyle changes and the use of digital technologies to complement their care. The interviews were audio recorded and transcribed verbatim. Reflexive thematic analysis enabled the development of themes from the data. Ethical approval was obtained from the National Health Service Health Research Authority. RESULTS: A total of 20 patients were interviewed (preoperative phase: 40% (8/20); postoperative phase: 60% (12/20). A total of 4 overarching themes were developed and related to the optimization of technology functionality. These centered on providing tailored content and support; facilitating self-monitoring and goal setting; delivering information in an accessible, trusted, and usable manner; and meeting patient information-seeking and engagement needs during the surgical pathway. Functionalities that delivered personalized feedback and postoperative follow-up were considered beneficial. Individualized goal setting functionality could support a generation of digitally engaged patients with bariatric conditions as working toward achievable targets was deemed an effective strategy for motivating behavior change. The creation of digital package of care checklists between patients and clinicians was a novel finding from this study. CONCLUSIONS: Perceptions of patients undergoing bariatric surgery validated the integration of digital technologies within the surgical pathway, offering enhanced connectedness and support. Recommendations are made relating to the design, content, and functionality of digital interventions to best address the needs of this cohort. These findings have the potential to influence the co-design and integration of person-centered, perioperative technologies.
