RESUMEN
BACKGROUND: Ashkenazi Jewish (AJ) people have a higher incidence of BRCA1/2 pathogenic variants (PVs) than unselected populations. Three BRCA-Jewish founder mutations (B-JFMs) comprise >90% of BRCA1/2 PVs in AJ people. Personal/family cancer history-based testing misses ≥50% of people with B-JFM. METHODS: We compared two population-based B-JFM screening programmes in Australia-using (1) an online tool (Sydney) and (2) in-person group sessions (Melbourne). RESULTS: Of 2167 Jewish people tested (Sydney n=594; Melbourne n=1573), 1.3% (n=28) have a B-JFM, only 2 of whom had a significant cancer family history (Manchester score ≥12). Pretest anxiety scores were normal (mean 9.9±3.5 (6-24)), with no significant post-result change (9.5±3.3). Decisional regret (mean 7.4±13.0 (0-100)), test-related distress (mean 0.8+/2.2 (0-30)) and positive experiences (reverse-scored) (mean 3.4±4.5 (1-20)) scores were low, with no significant differences between Sydney and Melbourne participants. Post-education knowledge was good overall (mean 11.8/15 (±2.9)) and significantly higher in Melbourne than Sydney. Post-result knowledge was the same (mean 11.7 (±2.4) vs 11.2 (±2.4)). Participants with a B-JFM had higher post-result anxiety and test-related distress and lower positive experiences, than those without a B-JFM, but scores were within the normal range. Family cancer history did not significantly affect knowledge or anxiety, or pretest perception of B-JFM or cancer risks. Most participants (93%) were satisfied/very satisfied with the programme. CONCLUSION: Both B-JFM screening programmes are highly acceptable to Australian Jewish communities. The programme enabled identification of several individuals who were previously unaware they have a B-JFM, many of whom would have been ineligible for current criteria-based testing in Australia.

INTRODUCTION: People of Ashkenazi Jewish (AJ) ancestry are more likely than unselected populations to have a BRCA1/2 pathogenic variant, which cause a significantly increased risk of breast, ovarian and prostate cancer. Three specific BRCA1/2 pathogenic variants, referred to as BRCA-Jewish founder mutations (B-JFM), account for >90% of BRCA1/2 pathogenic variants in people of AJ ancestry. Current practice of identifying eligible individuals for BRCA testing based on personal and/or family history has been shown to miss at least 50% of people who have one of these variants. Here we describe the protocol of the JeneScreen study-a study established to develop and evaluate two different population-based B-JFM screening programmes, offered to people of Jewish ancestry in Sydney and Melbourne, Australia. METHODS AND ANALYSIS: To rmeasure the acceptability of population-based B-JFM screening in Australia, two screening programmes using different methodologies have been developed. The Sydney JeneScreen programme provides information and obtains informed consent by way of an online tool. The Melbourne JeneScreen programme does this by way of community sessions attended in person. Participants complete questionnaires to measure clinical and psychosocial outcomes at baseline, and for those who have testing, 2 weeks postresult. Participants who decline testing are sent a questionnaire regarding reasons for declining. Participants with a B-JFM are sent questionnaires 12-month and 24-month post-testing. The questionnaires incorporate validated scales, which measure anxiety, decisional conflict and regret, and test-related distress and positive experiences, and other items specifically developed or adapted for the study. These measures will be assessed for each programme and the two population-based B-JFM screening methods will be compared. ETHICS AND DISSEMINATION: Institutional Human Research Ethics Committee approval was obtained from the South Eastern Area Health Service Human Research Ethics Committee: HREC Ref 16/125.Following the analysis of the study results, the findings will be disseminated widely through conferences and publications, and directly to participants in writing.

OBJECTIVE: To gain a better understanding of healthcare professionals' practice and attitudes regarding prenatal ß-thalassemia carrier screening in Australia. METHOD: Qualitative study with semi-structured interviews of healthcare professionals (obstetricians, general practitioners, midwives, genetic counselors, and hematologists) involved in prenatal thalassemia carrier screening in public and private practice. RESULTS: Twenty-three healthcare providers were interviewed and several themes emerged. Participants described and acknowledged inconsistencies in the ß-thalassemia screening processes, such as variability in ordering the tests, communicating the diagnosis, and action taken after diagnosis. They indicated a preference for more structure and valued the importance of screening guidelines but many of those involved in ordering the screening test were unaware of their availability. These healthcare professionals recognized they lacked knowledge regarding the screening process, and many had not undertaken education activities in this area in recent times. There were mixed views about the consent process, particularly at which stage this should be obtained, and what information is provided. CONCLUSIONS: ß-thalassemia screening in Victoria occurs with apparent lack of awareness of guidelines and an acknowledged preference for a more systematic process and educational support. Informed consent was not considered an important component of this screening process.

Tests for haemoglobinopathy carrier status are the commonest genetic screening tests undertaken internationally. Carrier screening for ß-thalassaemia is not coordinated in Victoria, Australia, and is instead incorporated into routine practice where most women are screened antenatally, through a full blood examination (FBE). Little is known about how women are screened for ß-thalassaemia in Australia as well as their attitudes towards the screening process. This study was conducted to explore carriers' and carrier couples' experiences of and attitudes towards ß-thalassaemia screening in Australia. Semi-structured interviews with 26 recently pregnant female carriers and ten carrier couples of ß-thalassaemia were carried out. Interviews were analysed using inductive content analysis. Unexpectedly, more than half of the women had been made aware of their carrier status prior to pregnancy, with FBEs carried out for numerous reasons other than thalassaemia screening. Most women did not recall being told about thalassaemia before notification of their carrier status and therefore did not make a decision about being screened. They were generally accepting for doctors to decide about testing; however, would have preferred to have been made aware of the screening test. Women also reported receiving insufficient information after being notified of their carrier status, leading to misconceptions and confusion. This genetic screening process, incorporated into routine care whereby informed decisions were not being made by patients, was apparently acceptable overall. Based on the results of this study, we make the following recommendations: (1) individuals should be made aware that they are being tested for thalassaemia at least before a specific thalassaemia diagnostic test is performed; (2) current understanding by known carriers of thalassaemia should be assessed and any misconceptions corrected; (3) written information should be provided to carriers; (4) referral of carrier couples to specialists in thalassaemia and genetics is strongly recommended; (5) the term 'carrier of ß-thalassaemia' should be used rather than 'thalassaemia minor'.
RESUMEN
BACKGROUND: Tools which assist practitioners to identify patient concerns and increase understanding of their needs can improve both the delivery of care and adherence to treatment. The aim of this study was to test the validity and reliability of a 14-item tool, to identify the unmet needs and concerns of older people with asthma. METHODS: The Patient Asthma Concerns Tool (PACT) was developed from a pool of 55 items derived from a comprehensive literature review. After pilot and field testing, the initial 55 item questionnaire was administered to a community sample (n = 193), psychometrically tested, and refined to a 14 item PACT tool which was evaluated by a group of clinicians. RESULTS: The PACT was shown to have good content and construct validity and was well received by clinicians. The PACT also correlated well with the Juniper ACQ and Brooks' adherence score on related variables and showed good reliability with good-excellent Kappa and ICC scores. Internal consistency of factors was high, and the overall Cronbach's α was 0.70. CONCLUSION: The PACT questionnaire was shown to be a valid and reliable tool clinically and psychometrically. We intend to test it in primary care settings and anticipate that its use will assist health professionals to identify the needs and concerns of older patients with asthma and direct tailored asthma management accordingly.

ß-thalassaemia is one of the most common single-gene inherited conditions in the world, and thalassaemia carrier screening is the most widely performed genetic screening test, occurring in many different countries. ß-thalassaemia carrier screening programmes provide a unique opportunity to compare the delivery of carrier screening programmes carried out in different cultural, religious and social contexts. This review compares the key characteristics of ß-thalassaemia carrier screening programmes implemented in countries across the world so that the differences and similarities between the programmes can be assessed. The manner in which thalassaemia carrier screening programmes are structured among different populations varies greatly in several aspects, including whether the programmes are mandatory or voluntary, the education and counselling provided and whether screening is offered pre-pregnancy or antenatally. National and international guidelines make recommendations on the most appropriate ways in which genetic carrier screening programmes should be conducted; however, these recommendations are not followed in many programmes. We discuss the implications for the ethical and acceptable implementation of population carrier screening and identify a paucity of research into the outcomes of thalassaemia screening programmes, despite the fact that thalassaemia screening is so commonly conducted.

BACKGROUND: Asthma is prevalent among elderly Australians but is often misdiagnosed and undertreated. Asthma presents with the same clinical features in the elderly as in the younger population. OBJECTIVE: This article identifies current knowledge about the needs of elderly people with asthma, as well as the knowledge gaps currently existing in this area of health care. DISCUSSION: A significant proportion of elderly people with asthma go undiagnosed. Elderly patients under-report symptoms and attribute breathlessness to age and other comorbidities. Other difficulties include impaired perception of asthma severity, poor medication adherence, physical disability, cognitive dysfunction, and a passive self management approach. These all contribute to poorer asthma outcomes among the elderly. The management of asthma among the elderly is likely to improve if specific needs are addressed with tailored educational interventions and appropriate care.
