Since the emergence of SARS-CoV-2, the virus that causes coronavirus disease (COVID-19) in late 2019, communities have been required to rapidly adopt community mitigation strategies rarely used before, or only in limited settings. This study aimed to examine the attitudes and beliefs of Australian adults towards the COVID-19 pandemic, and willingness and capacity to engage with these mitigation measures. In addition, we aimed to explore the psychosocial and demographic factors that are associated with adoption of recommended hygiene-related and avoidance-related behaviors. A national cross-sectional online survey of 1420 Australian adults (18 years and older) was undertaken between the 18 and 24 March 2020. The statistical analysis of the data included univariate and multivariate logistic regression analysis. The survey of 1420 respondents found 50% (710) of respondents felt COVID-19 would 'somewhat' affect their health if infected and 19% perceived their level of risk as high or very high. 84·9% had performed ≥1 of the three recommended hygiene-related behaviors and 93·4% performed ≥1 of six avoidance-related behaviors over the last one month. Adopting avoidance behaviors was associated with trust in government/authorities (aOR: 6.0, 95% CI 2.6-11·0), higher perceived rating of effectiveness of behaviors (aOR: 4·0, 95% CI: 1·8-8·7), higher levels of perceived ability to adopt social distancing strategies (aOR: 5.0, 95% CI: 1·5-9.3), higher trust in government (aOR: 6.0, 95% CI: 2.6-11.0) and higher level of concern if self-isolated (aOR: 1.8, 95% CI: 1.1-3.0). In the last two months, members of the public have been inundated with messages about hygiene and social (physical) distancing. However, our results indicate that a continued focus on supporting community understanding of the rationale for these strategies, as well as instilling community confidence in their ability to adopt or sustain the recommendations is needed.

Background As immunisation program launches have previously demonstrated, it is essential that careful planning occurs now to ensure the readiness of the public for a COVID-19 vaccine. As part of that process, this study aimed to understand the public perceptions regarding a future COVID-19 vaccine in Australia. Methods A national cross-sectional online survey of 1420 Australian adults (18 years and older) was undertaken between 18 and 24 March 2020. The statistical analysis of the data included univariate and multivariable logistic regression model analysis. Results Respondents generally held positive views towards vaccination. Eighty percent ( n  = 1143) agreed with the statement that getting myself vaccinated for COVID-19 would be a good way to protect myself against infection . Females ( n  = 614, 83%) were more likely to agree with the statement than males ( n  = 529, 78%) (aOR = 1.4 (95% CI: 1.1–1.8); P  = 0.03), while 91% of those aged 70 years and above agreed compared to 76% of 18–29-year-olds (aOR = 2.3 (95% CI:1.2–4.1); P  = 0.008). Agreement was also higher for those with a self-reported chronic disease (aOR = 1.4 (95% CI: 1.1–2.0); P  = 0.04) and among those who held private health insurance (aOR = 1.7 (95% CI: 1.3–2.3); P  < 0.001). Beyond individual perceptions, 78% stated that their decision to vaccinate would be supported by family and friends. Conclusion This study presents an early indication of public perceptions towards a future COVID-19 vaccine and represents a starting point for mapping vaccine perceptions. To support an effective launch of these new vaccines, governments need to use this time to understand the communities concerns and to identify the strategies that will support engagement.

Background Medical degree programs use scholarly activities to support development of basic research skills, critical evaluation of medical information and promotion of medical research. The University of Sydney Doctor of Medicine Program includes a compulsory research project. Medical student projects are supervised by academic staff and affiliates, including biomedical science researchers and clinician-academics. This study investigated research supervisors’ observations of the barriers to and enablers of successful medical student research projects. Methods Research supervisors ( n  = 130) completed an anonymous, online survey after the completion of the research project. Survey questions targeted the research supervisors’ perceptions of barriers to successful completion of projects and sources of support for their supervision of the student project. Data were analysed by descriptive statistics and using manifest content analysis. Further quantitative investigation was made by cross-tabulation according to prior research supervision experience. Results Research supervisors reported that students needed both generic skills (75%) and research-based skills (71%) to successfully complete the project. The major barrier to successful research projects was the lack of protected time for research activities (61%). The assessment schedule with compulsory progress milestones enabled project completion (75%), and improved scientific presentation (90%) and writing (93%) skills. Supervisors requested further support for their students for statistics (75%), scientific writing (51%), and funding for projects (52%). Prior research supervision experience influenced the responses. Compared to novice supervisors, highly experienced supervisors were significantly more likely to want students to be allocated dedicated time for the project ( P  < 0.01) and reported higher rates of access to expert assistance in scientific writing, preparing ethics applications and research methodology. Novice supervisors reported higher rates of unexpected project delays and data acquisition problems ( P  < 0.05). Co-supervision was favoured by experienced supervisors but rejected by novice supervisors. Conclusions Both generic and research-related skills were important for medical student research project success. Overall, protected research time, financial and other academic support were identified as factors that would improve the research project program. Prior research supervision experience influences perceptions of program barriers and enablers. These findings will inform future support needs for projects and research supervisor training for the research supervision role.

Purpose To prospectively assess patient reported outcomes and risk management behavior of women choosing to receive (receivers) or decline (decliners) their breast cancer polygenic risk score (PRS). Methods Women either unaffected or affected by breast cancer and from families with no identified pathogenic variant in a breast cancer risk gene were invited to receive their PRS. All participants completed a questionnaire at study enrollment. Receivers completed questionnaires at two weeks and 12 months after receiving their PRS, and decliners a second questionnaire at 12 months post study enrollment. Results Of the 208 participants, 165 (79%) received their PRS. Among receivers, there were no changes in anxiety or distress following testing. However, compared to women with a low PRS, those with a high PRS reported greater genetic testing–specific distress, perceived risk, decisional regret, and less genetic testing–positive response. At 12 months, breast screening and uptake of risk-reducing strategies were consistent with current Australian guidelines of breast cancer risk management. Reasons for declining PRS included being unable to attend the appointment in person and concerns over potential emotional response. Conclusion The outcomes of the study provide insight into women’s responses to receiving PRS and highlight the issues that need to be addressed in the associated model of genetic counseling.

Background Early Childhood Education Centre (ECEC) staff are strongly recommended to receive several immunizations including influenza and pertussis. However, evidence regarding the uptake is either old or lacking across all Australian States/Territories. This study aimed to explore the attitudes and barriers around ECEC staff vaccination and the immunisation policy/practices employed at their workplaces. Methods An online cross-sectional survey was undertaken of staff members (administrators and childcare center staff) in early 2017. We compared the individual’s knowledge, attitude and practices as well as the centre’s policy and practice variables between the vaccinated and unvaccinated respondents. A logistic model was used to identify the factors associated with uptake of the different vaccines. Results A total of 575 ECEC staff completed the survey. Sixty percent reported being aware of the recommendations about staff immunisation. While participants did acknowledge that they could spread diseases if unvaccinated (86%), 30% could not recall receiving a dTpa in the last 10 years. Private centres were less likely to provide free or onsite vaccination compared to other categories of centres. Less than half reported receiving any encouragement to get the influenza vaccine and only 33% reported that their centre provides onsite influenza vaccination. Regarding the introduction of mandatory policies, 69% stated that they would support a policy. Conclusion Employers should consider supporting methods to maximize vaccination of their employees including providing free onsite vaccination. Participants were open to idea of mandatory vaccination; however, this needs to be explored further to determine how vaccine costs and access issues could be resolved.

Background Research activities undertaken during University studies contribute to preparation of medical students for practice of evidence-based medicine. This study aimed to understand medical students’ experiences, perceived research skills development and satisfaction associated with completion of mandatory research projects. Methods An online survey was sent to five cohorts of students (n = 1375) from years 2017–2021 at the completion of their research projects. Univariate analysis was conducted to understand students’ perception of research skills development, followed by linear regression modeling to explore factors influencing satisfaction with their research project. Manifest content analysis employing a framework approach was used to analyse qualitative data from responses to open ended questions. Results Response rate was 42%, with 513 (89%) returned surveys being complete and included in analysis. Whilst 37% of students felt they had requisite research skills before undertaking the research project, 84% reported they had these skills after completing the project (χ 2  = 8.99, P = 0.02). Mean satisfaction score of the students was 5.0/10 (+/- 2.5, median = 6 (IQR = 3.0–7.0) with 59% of students reporting satisfaction scores higher than the average. Higher satisfaction scores were reported by those who perceived that: research methods and teaching was useful in preparing them for conducting research; the research project helped them acquire new skills; the project resulted in peer-reviewed publication; and, who felt supported by their supervisors. Responses to open ended questions offered important insights into student experience and emphasised the importance of supportive supervisors and the need for a dedicated research block in the busy medical program. Conclusions The majority of students reported positive outcomes from the mandatory research project. Student satisfaction can be improved by ensuring supportive research environments and high-quality supervision, and inclusion of dedicated research time in the medical curriculum.

Background The incidence of hypothyroidism following hemithyroidectomy and risk factors associated with its occurrence are not completely understood. This systematic review investigated the incidence and risk factors for hypothyroidism, thyroxine supplementation following hemithyroidectomy as well as the course of post-operative hypothyroidism, including the time to hypothyroidism and incidence of transient hypothyroidism. Methods Searches were conducted in MEDLINE, EMBASE, Scopus, and Cochrane library for studies reporting the incidence of hypothyroidism or thyroxine supplementation following hemithyroidectomy. Results Sixty-six studies were eligible for inclusion: 36 reported risk factors, and 27 reported post-operative course of hypothyroidism. Median follow-up was 25.2 months. The pooled incidence of hypothyroidism was 29% (95% CI, 25-34%; P <0.001). Transient hypothyroidism occurred in 34% of patients (95% CI, 21-47%; P <0.001). The pooled incidence of thyroxine supplementation was 23% (95% CI, 19-27%; P <0.001), overt hypothyroidism 4% (95% CI, 2-6%, P <0.001). Risk factors for development of hypothyroidism included pre-operative thyroid stimulating hormone (TSH) (WMD, 0.87; 95% CI, 0.75-0.98; P <0.001), TSH ≥ 2 mIU/L (RR, 2.87; 95% CI, 2.43-3.40; P <0.001), female sex (RR, 1.19; 95% CI, 1.08-1.32; P =0.007), age (WMD, 2.29; 95% CI, 1.20-3.38; P <0.001), right sided hemithyroidectomy (RR, 1.35; 95% CI, 1.10-1.65, P =0.003), the presence of autoantibodies anti-TPO (RR, 1.92; 95% CI, 1.49-2.48; P <0.001), anti-Tg (RR, 1.53; 95% CI, 1.40-1.88; P <0.001), and Hashimoto’s thyroiditis (RR, 2.05; 95% CI, 1.57-2.68; P =0.001). Conclusion A significant number of patients will develop hypothyroidism or require thyroxine following hemithyroidectomy. An awareness of patient risk factors and postoperative thyroid function course will assist in counselling patients on their risk profile and guiding management.

Background Access to information about prenatal screening is important particularly in light of new techniques such as non-invasive prenatal testing (NIPT). This study aimed to develop and examine the acceptability of a low literacy decision aid (DA) about Down syndrome screening among pregnant women with varying education levels and GPs. Methods We developed a DA booklet providing information about first-trimester combined testing, maternal serum screening, and NIPT. GPs and women participated in a telephone interview to examine the acceptability of the DA and measure screening knowledge before and after reading the DA. The knowledge measure was designed to assess whether women had understood the gist of the information presented in the decision aid. It comprised conceptual questions (e.g. screening tells you the chance of having a baby with Down syndrome) and numeric questions (e.g. the accuracy of different screening tests). Results Twenty-nine women and 18 GPs participated. Regardless of education level, most women found the booklet ‘very’ clearly presented ( n  = 22, 76%), and ‘very’ informative ( n  = 23, 80%). Overall, women’s conceptual and numeric knowledge improved after exposure to the DA, from 4% having adequate knowledge to 69%. Women’s knowledge of NIPT also improved after receiving the decision aid, irrespective of education. Most GPs found it ‘very’ clearly presented ( n  = 13, 72%), and that it would ‘very much’ facilitate decision-making ( n  = 16, 89%). Conclusions The DA was found to be acceptable to women as well as GPs. A comprehensive evaluation of the efficacy of the decision aid compared to standard information is an important next step. Strategies are needed on how to implement the tool in practice.

The purpose of this study was to examine correlations between health indicators (age, BMI, blood pressure (BP), functional strength (FS), handgrip strength, and predicted VO2 max) and carotid intima-media thickness (cIMT) in an active 50 years+ population. Study participants’ mean cIMT was also compared to the cIMT mean of the general population. Health screenings were conducted on 1818 participants at the Huntsman World Senior Games from 2016 to 2019. Pearson’s correlations, Spearman’s correlations, and ANOVA were performed using SPSS. Weak but significant correlations were evident between cIMT and age (r = 0.283, p < 0.001), systolic BP (r = 0.253, p = 0.001), diastolic BP (r = 0.074, p = 0.016), weight (r = 0.170, p < 0.001), height (r = 0.153, p < 0.001), handgrip L (r = 0.132, p < 0.001), handgrip R (r = 0.074, p < 0.029), and BMI (r = 0.07, p = 0.029); non-significant correlations were evident with predicted VO2 max (r = −0.035, p = 0.382), and FS (r = −0.025, p = 0.597). When controlling for age, systolic BP, and sex, only handgrip L (r = 0.225, p = 0.014) was significantly correlated with cIMT. Mean cIMT for this cohort was lower across all sexes and age-matched groups (cIMT = 0.6967 mm (±0.129)). Physical activity is linked to reduced cIMT. Most health-related indicators in this study were significantly but weakly correlated with cIMT. Additional research is needed before common indicators can be used as a surrogate for cIMT and CVD risk. Results from this study can provide clinicians with additional information to reduce CVD risk through modifiable risk factors. Classic CVD risk factors such as systolic BP and BMI should be considered in patients regardless of lifestyle.

Background The ‘common variant, common disease’ model predicts that a significant component of hereditary breast cancer unexplained by pathogenic variants in moderate or high-penetrance genes is due to the cumulative effect of common risk variants in DNA (polygenic risk). Assessing a woman’s breast cancer risk by testing for common risk variants can provide useful information for women who would otherwise receive uninformative results by traditional monogenic testing. Despite increasing support for the utility of common risk variants in hereditary breast cancer, research findings have not yet been integrated into clinical practice. Translational research is therefore critical to ensure results are effectively communicated, and that women do not experience undue adverse psychological outcomes. Methods In this prospective study, 400 women with a personal and/or high risk family history of breast cancer will be recruited from six familial cancer centers (FCCs) in Australia. Eligible women will be invited to attend a FCC and receive their personal polygenic risk result for breast cancer. Genetic health professionals participating in the study will receive training on the return of polygenic risk information and a training manual and visual aids will be developed to facilitate patient communication. Participants will complete up to three self-administered questionnaires over a 12-months period to assess the short-and long-term psychological and behavioral outcomes of receiving or not receiving their personal polygenic risk result. Discussion This is the world’s first study to assess the psychological and behavioral impact of offering polygenic risk information to women from families at high risk of breast cancer. Findings from this research will provide the basis for the development of a new service model to provide polygenic risk information in familial cancer clinics. Trial registration The study was retrospectively registered on 27th April 2017 with the Australian and New Zealand Clinical Trials Group (Registration no: ACTRN12617000594325; clinical trial URL: https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=372743 ).
