Antifungal prophylaxis in lung transplantation

Neoh CF, Snell G, Levvey B, Morrissey CO, Stewart K, Kong DC

Int J Antimicrob Agents, 2014 Sep;44(3):194-202.
PMID: 25123811 DOI: 10.1016/j.ijantimicag.2014.05.013

Lung transplant (LTx) patients have an increased risk of developing invasive fungal infections (IFIs), particularly invasive aspergillosis. Rapid identification of the causative fungal pathogen, to allow for early administration of appropriate initial antifungal therapy, in LTx patients has been challenging due to the limited sensitivity and specificity of the diagnostic tools. Hence, there is increasing emphasis on antifungal prophylaxis in the LTx setting, given the high mortality rates and substantial cost of treating IFIs. Evidence for the optimal antifungal prophylactic approach in this setting, however, remains scant and inconsistent. This review will briefly discuss the epidemiology, risk factors, timing and clinical manifestations of fungal infections in LTx patients and will focus primarily on the available evidence related to the efficacy, safety and practicality of current prophylactic strategies in LTx recipients as well as challenges and gaps for future research.
Clinical utility of caspofungin eye drops in fungal keratitis

Neoh CF, Daniell M, Chen SC, Stewart K, Kong DC

Int J Antimicrob Agents, 2014 Aug;44(2):96-104.
PMID: 24933448 DOI: 10.1016/j.ijantimicag.2014.04.008

Treatment of fungal keratitis remains challenging. To date, only the polyenes and azoles are commonly used topically in the management of fungal keratitis. Natamycin, a polyene, is the only antifungal eye drop that is commercially available; the remainder are prepared in-house and are used in an 'off-label' manner. Failure of medical treatment for fungal keratitis is common, hence there is a need for more effective topical antifungal therapy. To increase the antifungal eye drop armamentarium, it is important to investigate the utility of other classes of antifungal agents for topical use. Caspofungin, an echinocandin antifungal agent, could potentially be used to address the existing shortcomings. However, little is known about the usefulness of topically administered caspofungin. This review will briefly explore the incidence, epidemiology and antifungal treatment of fungal keratitis. It will focus primarily on evidence related to the efficacy, safety and practicality of using caspofungin eye drops in fungal keratitis.
Echinocandins in the treatment of candidaemia and invasive candidiasis: clinical and economic perspectives

Neoh CF, Slavin M, Chen SC, Stewart K, Kong DC

Int J Antimicrob Agents, 2014 Mar;43(3):207-14.
PMID: 24670423 DOI: 10.1016/j.ijantimicag.2013.08.010

Candidaemia and invasive candidiasis (IC) complicate modern medical therapy, contributing to high morbidity and mortality. Managing candidiasis is costly, with an additional healthcare expenditure of nearly US$300 million annually. Recent consensus guidelines have suggested the use of newer antifungal agents, such as echinocandins, for the treatment of candidaemia and IC owing to promising clinical outcomes compared with older-generation antifungal agents, but at higher drug acquisition and administration costs. Comprehensive cost-effectiveness data for echinocandins in treating candidaemia and IC remain relatively scant, underlining the need for more studies to incorporate robust economic analyses into clinical decisions. Assessment of the cost efficiencies of these expensive antifungal agents is essential for maximising health outcomes within the constraints of healthcare resources. This review will explore the epidemiology of candidaemia and IC in the context of clinical and economic aspects of the antifungal agents used to treat IC, especially the echinocandins. Standardising the outcome measure, methodology and reporting of results used in economic studies is central to ensure validity and comparability of the findings. Future studies comparing the economic advantages of all available antifungal treatment options and in the context of new diagnostic tools for fungal infections are anticipated.
Toward cultural competence in cancer genetic counseling and genetics education: lessons learned from Chinese-Australians

Barlow-Stewart K, Yeo SS, Meiser B, Goldstein D, Tucker K, Eisenbruch M

Genet Med, 2006 Jan;8(1):24-32.
PMID: 16418596

PURPOSE: In societies such as Australia with a strong multicultural makeup, culturally determined attitudes to genetics, testing, and counseling may be incompatible with current genetics service provision.
METHODS: An ethnographic investigation using purposive sampling to increase subject diversity was used to explore the range of beliefs about kinship and inheritance using Chinese-Australians as a case. Participants comprised a sample of 15 Chinese-Australians who had been recruited through several community-based organizations.
RESULTS: The level of acculturation does not correlate with holding beliefs about inheritance, kinship, and causes of hereditary cancer that are based on "Western" biomedical or traditional concepts. Mismatch between beliefs may exist within families that can impact participation in cancer genetic testing. Family history taking that underpins the surveillance, management, and referral to genetic counseling where there is a strong family history of breast, ovarian, or colorectal cancer can also be impacted unless recognition is made of the patrilineal concept of kinship prevalent in this Chinese-Australian community.
CONCLUSION: This community-based study confirmed and validated views and beliefs on inheritance and kinship and inherited cancer attributed to senior family members by Chinese-Australians who attended cancer genetic counseling. Barriers to communication can occur where there may be incompatibility within the family between "Western" and traditional beliefs. The findings were used to develop strategies for culturally competent cancer genetic counseling with Australian-Chinese patients. These include nonjudgmental incorporation of their belief systems into the genetic counseling process and avoidance of stereotyping. They have also influenced the development of genetics education materials to optimize family history taking.

The needs of Southeast Asian BRCA mutation carriers considering risk-reducing salpingo-oophorectomy: a qualitative study

Sa'at H, Lee YK, Yoon SY, Wong SW, Woo YL, Barlow-Stewart K, et al.

The decision to have risk-reducing salpingo-oophorectomy (RRSO) by BRCA mutation carriers to reduce the risk of ovarian cancer is difficult. The choice involves trade-offs in terms of its risks and benefits. To date, understanding the decision-making needs of RRSO among Southeast Asian BRCA mutation carriers is limited. This study aimed to explore the decision-making needs of Malaysian BRCA mutation carriers as an exemplar for the Southeast Asian community. In-depth interviews and clinic observations were conducted with 31 BRCA mutation carriers and analysed thematically. The core theme identified was 'Coping with complex information and alleviating uncertainties' with the following subthemes: (1) the need for an adjustment period, (2) information support, (3) social support and, (4) religious support. We found that women required time to accept their BRCA mutation status before they were ready to make a risk-reducing choice; that understanding complex genetic information and multiple risk management options can be an overwhelming experience; and obtaining further information and a second opinion were challenging. Many described the need for experiential information from other peer-carriers who had undergone RRSO. Support from their spouse and family members was thought to be essential for them to feel reassured with their decision. Many relied on religion to positively cope with cancer risk and cancer worry; Muslim BRCA carriers sought religious guidance through prayers and Islamic fatwas to feel more certain about their RRSO decision. These findings underscore the importance of the provision of resources and support that includes input from peers, husband, family members and religion to underpin the decision-making needs of Malaysian BRCA mutation carriers considering RRSO.
Decision-making for Risk-reducing Salpingo-oophorectomy (RRSO) in Southeast Asian BRCA Mutation Carriers With Breast Cancer: A Qualitative Study

Sa'at H, Lee YK, Yoon SY, Wong SW, Woo YL, Barlow-Stewart K, et al.

Int J Behav Med, 2022 Feb;29(1):1-13.
PMID: 33791992 DOI: 10.1007/s12529-021-09984-y

BACKGROUND: The uptake of risk-reducing salpingo-oophorectomy (RRSO) in Asian countries is variable despite being the most effective option for ovarian cancer risk reduction in BRCA mutation carriers. Exploration of factors which may impact the RRSO decision-making of BRCA mutation carriers from Malaysia, a developing country in Southeast Asia, was undertaken.
METHODS: In-depth interviews with 28 Malaysian BRCA mutation carriers with a history of breast cancer were conducted in addition to observing their RRSO decision-making consultations in the clinic.
RESULTS: The decision-making considerations among the carriers were centered around the overarching theme of "Negotiating cancer risk and womanhood priorities," with the following themes: (1) risk perception, (2) self-preservation, (3) motherhood obligation, and (4) the preciousness of marriage. Cognitive knowledge of BRCA risk was often conceptualized based on personal and family history of cancer, personal beliefs, and faith. Many women reported fears that RRSO would affect them physically and emotionally, worrying about the post-surgical impact on their motherhood responsibilities. Nevertheless, some reported feeling obliged to choose RRSO for the sake of their children. For some, their husband's support and approval were critical, with emotional well-being and sexuality reportedly perceived as important to sustaining married life. Despite reporting hesitancy toward RRSO, women's decisions about choosing this option evolved as their priorities changed at different stages of life.
CONCLUSIONS: Recognizing during clinic encounters with Malaysian women that RRSO decision-making involves negotiating the likelihood of developing cancer with the societal priorities of being a woman, mother, and wife may serve to support their decision-making.
Fulltext Open-Label Study of Absorption and Clearance of 1% Voriconazole Eye Drops

Neoh CF, Leung L, Chan E, Al-Badriyeh D, Fullinfaw RO, Jhanji V, et al.

Antimicrob Agents Chemother, 2016 11;60(11):6896-6898.
PMID: 27550348 DOI: 10.1128/AAC.00683-16

Twenty participants undergoing elective cataract surgery received 1% voriconazole eye drops (1 drop per eye) either 20, 40, 60, or 80 min before surgery. Median voriconazole concentrations of 1.9 to 3.2 mg/liter in aqueous humor samples were attained over the first 80 min, which were higher than in vitro MIC90 values for typical fungi that cause keratitis.
Fulltext The Global State of the Genetic Counseling Profession

Abacan M, Alsubaie L, Barlow-Stewart K, Caanen B, Cordier C, Courtney E, et al.

Eur J Hum Genet, 2019 Feb;27(2):183-197.

The profession of genetic counseling (also called genetic counselling in many countries) began nearly 50 years ago in the United States, and has grown internationally in the past 30 years. While there have been many papers describing the profession of genetic counseling in individual countries or regions, data remains incomplete and has been published in diverse journals with limited access. As a result of the 2016 Transnational Alliance of Genetic Counseling (TAGC) conference in Barcelona, Spain, and the 2017 World Congress of Genetic Counselling in the UK, we endeavor to describe as fully as possible the global state of genetic counseling as a profession. We estimate that in 2018 there are nearly 7000 genetic counselors with the profession established or developing in no less than 28 countries.
