The COVID-19 pandemic has affected different parts of Australia in distinct ways across 2020 and 2021. In 2020, Melbourne was the epicentre of COVID-19. As one of the key tertiary centres caring for the patients affected by the outbreaks, the Royal Melbourne Hospital (RMH) managed the majority of the Victorian inpatient caseload.To review the demographics, management and outcomes of patients with COVID-19 cared for by the RMH services in 2020.A single health service retrospective cohort analysis of demographics, interventions and outcomes was conducted to characterise the RMH experience in 2020.From January to December 2020, 433 patients required admission more than 24 h. The demographics of affected patients and outcomes changed over the course of the study. Overall, 47% (203/433) required oxygen, most frequently (36%; 154/433) with low-flow devices (nasal prongs or hudson mask), and 11% (47/433) of patients required admission to intensive care. We recorded a 30-day mortality of 24% (104/433) mortality overall, rising to over 50% in patients aged over 80 years.The experience of this health service in 2020 demonstrated changing demographics over time, with associated differences in outcomes; notably marked mortality in older populations, frequent complications and limited inter-site transfer possible with mobilised resources.

Background An estimated 292 million people are living with chronic hepatitis B virus (HBV) infection globally, including 223,000 people in Australia. HBV diagnosis and linkage of people living with HBV to clinical care is suboptimal in Australia, with 27% of people living with HBV undiagnosed and 77% not receiving regular HBV clinical care. This systematic review aimed to characterize population-level interventions implemented to enhance all components of HBV care cascade and analyse the effectiveness of interventions. Review questions Question 1: What population-level interventions, programs or policy approaches have been shown to be effective in reducing the incidence of hepatitis B; and that may not yet be fully rolled out or evaluated in Australia demonstrate early effectiveness, or promise, in reducing the incidence of hepatitis B? Question 2: What population-level interventions and/or programs are effective at reducing disease burden for people in the community with hepatitis B? Methods Four bibliographic databases and 21 grey literature sources were searched. Studies were eligible for inclusion if the study population included people with or at risk of chronic HBV, and the study conducted a population-level interventions to decrease HBV incidence or disease burden or to enhance any components of HBV care cascade (i.e., diagnosis, linkage to care, treatment initiation, adherence to clinical care), or HBV vaccination coverage. Studies published in the past 10 years (since January 2012), with or without comparison groups were eligible for inclusion. Studies conducting an HBV screening intervention were eligible if they reported proportion of people participating in screening, proportion of newly diagnosed HBV (participant was unaware of their HBV status), proportion of people received HBV vaccination following screening, or proportion of participants diagnosed with chronic HBV infection who were linked to HBV clinical care. Studies were excluded if study population was less than 20 participants, intervention included a pharmaceutical intervention or a hospital-based intervention, or study was implemented in limited clinical services. The records were initially screened by title and abstract. The full texts of potentially eligible records were reviewed, and eligible studies were selected for inclusion. For each study included in analysis, the study outcome and corresponding 95% confidence intervals (95%CIs) were calculated. For studies including a comparison group, odds ratio (OR) and corresponding 95%CIs were calculated. Random effect meta-analysis models were used to calculate the pooled study outcome estimates. Stratified analyses were conducted by study setting, study population, and intervention-specific characteristics. Key findings A total of 61 studies were included in the analysis. A large majority of studies (study n=48, 79%) included single-arm studies with no concurrent control, with seven (12%) randomised controlled trials, and six (10%) non-randomised controlled studies. A total of 109 interventions were evaluated in 61 included studies. On-site or outreach HBV screening and linkage to HBV clinical care coordination were the most frequent interventions, conducted in 27 and 26 studies, respectively. Question 1 We found no studies reporting HBV incidence as the study outcome. One study conducted in remote area demonstrated that an intervention including education of pregnant women and training village health volunteers enhanced coverage of HBV birth dose vaccination (93% post-intervention, vs. 81% pre-intervention), but no data of HBV incidence among infants were reported. Question 2 Study outcomes most relevant to the HBV burden for people in the community with HBV included, HBV diagnosis, linkage to HBV care, and HBV vaccination coverage. Among randomised controlled trials aimed at enhancing HBV screening, a meta-analysis was conducted including three studies which implemented an intervention including community face-to-face education focused on HBV and/or liver cancer among migrants from high HBV prevalence areas. This analysis demonstrated a significantly higher HBV testing uptake in intervention groups with the likelihood of HBV testing 3.6 times higher among those participating in education programs compared to the control groups (OR: 3.62, 95% CI 2.72, 4.88). In another analysis, including 25 studies evaluating an intervention to enhance HBV screening, a pooled estimate of 66% of participants received HBV testing following the study intervention (95%CI: 58-75%), with high heterogeneity across studies (range: 17-98%; I-square: 99.9%). A stratified analysis by HBV screening strategy demonstrated that in the studies providing participants with on-site HBV testing, the proportion receiving HBV testing (80%, 95%CI: 72-87%) was significantly higher compared to the studies referring participants to an external site for HBV testing (54%, 95%CI: 37-71%). In the studies implementing an intervention to enhance linkage of people diagnosed with HBV infection to clinical care, the interventions included different components and varied across studies. The most common component was post-test counselling followed by assistance with scheduling clinical appointments, conducted in 52% and 38% of the studies, respectively. In meta-analysis, a pooled estimate of 73% of people with HBV infection were linked to HBV clinical care (95%CI: 64-81%), with high heterogeneity across studies (range: 28-100%; I-square: 99.2%). A stratified analysis by study population demonstrated that in the studies among general population in high prevalence countries, 94% of people (95%CI: 88-100%) who received the study intervention were linked to care, significantly higher than 72% (95%CI: 61-83%) in studies among migrants from high prevalence area living in a country with low prevalence. In 19 studies, HBV vaccination uptake was assessed after an intervention, among which one study assessed birth dose vaccination among infants, one study assessed vaccination in elementary school children and 17 studies assessed vaccination in adults. Among studies assessing adult vaccination, a pooled estimate of 38% (95%CI: 21-56%) of people initiated vaccination, with high heterogeneity across studies (range: 0.5-93%; I square: 99.9%). A stratified analysis by HBV vaccination strategy demonstrated that in the studies providing on-site vaccination, the uptake was 78% (95%CI: 62-94%), significantly higher compared to 27% (95%CI: 13-42%) in studies referring participants to an external site for vaccination. Conclusion This systematic review identified a wide variety of interventions, mostly multi-component interventions, to enhance HBV screening, linkage to HBV clinical care, and HBV vaccination coverage. High heterogeneity was observed in effectiveness of interventions in all three domains of screening, linkage to care, and vaccination. Strategies identified to boost the effectiveness of interventions included providing on-site HBV testing and vaccination (versus referral for testing and vaccination) and including community education focussed on HBV or liver cancer in an HBV screening program. Further studies are needed to evaluate the effectiveness of more novel interventions (e.g., point of care testing) and interventions specifically including Indigenous populations, people who inject drugs, men who have sex with men, and people incarcerated.

Background Mother-to-child transmission (MTCT) of hepatitis B can be prevented with targeted interventions; however, MTCT continues to occur in Australia and globally. This qualitative research investigated how mothers with chronic hepatitis B (CHB) understand and experience interventions for the prevention of MTCT of CHB (PMTCT-CHB) in Victoria, Australia. Methods Semi-structured interviews were conducted with women with CHB. Participants were recruited through purposive and snowballing sampling. Interviews explored the women’s experience of care for themselves and their infants aimed at PMTCT-CHB. Interviews were conducted over the phone with a qualified interpreter where required. The consolidated criteria for reporting qualitative research framework was used with data thematically analysed. This study was co-designed with mothers with CHB through a Community Advisory Group established for this research; coordinated and supported by LiverWELL and the researchers. Results Sixteen women were interviewed. Although most women understood the purpose of hepatitis B vaccination, there were significant gaps in information and education provided to mothers regarding PMTCT-CHB. These gaps included understanding of the extent of protection of vaccination, breastfeeding with CHB, post-vaccination testing for infants and lack of clarity of the woman’s own hepatitis B status. There was notable fear and worry associated with hepatitis B transmission, with emotional support for mothers identified as a major gap in service delivery. Additionally, some women experienced stigma and discrimination due to their hepatitis B and refugee status. Conclusions This study explored how mothers with CHB understand and experience interventions to prevent MTCT. Our findings reveal substantial gaps in delivery of information and care in the context of PMTCT-CHB in Victoria. Our findings can support development of evidence-based interventions and systems to improve healthcare for mothers with CHB and their infants, and thereby reduce possible CHB transmission and other negative outcomes, including stigma and discrimination.

We report the kinetics of the immune response in relation to clinical and virological features of a patient with mild-to-moderate coronavirus disease-19 (COVID-19) requiring hospitalisation. Increased antibody-secreting cells, follicular T-helper cells, activated CD4+ and CD8+ T-cells and IgM/IgG SARS-CoV-2-binding antibodies were detected in blood, prior to symptomatic recovery. These immunological changes persisted for at least 7 days following full resolution of symptoms, indicating substantial anti-viral immunity in this non-severe COVID-19.

Hepatocellular carcinoma (HCC) surveillance reduces mortality in at-risk people living with chronic hepatitis B (CHB), but is difficult to achieve in practice. The objective of this study was to measure participation and adherence to liver cancer HCC surveillance in eligible patients in a community health centre, following support from the Integrated Hepatitis B Service (IHBS).A retrospective analysis of the medical records of patients with CHB who met the indications for HCC surveillance over a 4.5-year period of IHBS involvement was conducted. Data collected included the date of ultrasound examinations and HBV DNA viral load tests.Sixty-seven patients underwent HCC surveillance, representing 213 person years. The participation rate was 75%. Adherence to surveillance was considered good in 18 (27%) patients, suboptimal in 29 (43%) patients and poor in 20 (30%) patients. A greater proportion of patients were receiving HCC surveillance at the final audit (56%) than at baseline (10%; P DISCUSSION: It is difficult to achieve optimal adherence to HCC surveillance, even with additional support.

Incidence (see final page for Glossary) and mortality due to cancer have increased gradually since the nineteenth century and represent an enormous burden in the world. As already mentioned, the risk of cancer increases with age, and it has been observed also that the incidence of cancer and mortality due to the disease increases because of the population growth (National Cancer Institute. Cancer risk factors and protective factors. www.cancer.gov/about-cancer/causes-prevention/risk/age. (Accessed May 1 2018)). This situation is observed of course in the developed countries but also in the developing part of the world since nearly 44% of cancer cases and 53% of cancer deaths occur in countries at a low or medium level of the Human Development Index (International Agency for Research on Cancer and Cancer Research UK. World Cancer Factsheet. Cancer Research UK, London, 2014).

There has been substantial development in both clinical and public health approaches to hepatitis B virus (HBV), including more potent treatments and improved knowledge of the natural history of disease, policy changes, educational programs for health professionals, and improved support and information for people living with HBV.This article discusses some of the key clinical questions that arise in the management of HBV, with a focus on actions that can reduce the impact of chronic hepatitis B on individuals and the community, and the recent developments that will have a substantial impact on the management of HBV in Australian general practice.With recent developments in clinical and public health approaches, recognition of the need to address chronic hepatitis B has gained urgency, with current estimates suggesting that approximately 218,000 Australians are living with the disease, and that liver cancer is now the fastest increasing cause of cancer death in the country.
