Online tool to support expectant parents with prenatal testing decisions An online tool has been launched to support expectant parents in their choices around prenatal testing for chromosome conditions in their unborn baby. YourChoice, created by the Murdoch Children's Research Institute (MCRI) and James Cook University (JCU), aims to guide pregnant women through the prenatal testing options and which tests may be best suited for them. The interactive website features a 15‐minute decision aid that guides the user through a series of questions and suggests a preferred testing pathway based on their answers. The results can then be saved to discuss later with a health professional. MCRI's Professor Jane Halliday said the website was designed to ensure women and their partners could have informed discussions with their maternity care provider. “Our decision aid asks women about their values and preferences and provides them with suggested options to discuss with a health professional. There are many different prenatal tests available now, which makes it hard for people to navigate the system. We hope this tool will help women make informed decisions about whether or not to have testing and to understand the range of tests available to them.” JCU's Professor Cate Nagle said the decision aid was not a stand‐alone tool and worked alongside clinical support. “It's not meant to take the place of the doctor or midwife,” she said. “Pregnancy visits can be quick and don't always allow for in‐depth discussions around screening options, which are quite complex to understand. The website provides a summary as well as extra information and resources so every woman can find what she's looking for at her fingertips.” https://yourchoice.mcri.edu.au/dashboard Omega‐3 fatty acid could boost IQ for preterm babies Research from the South Australian Health and Medical Research Institute has found a link between the omega‐3 fatty acid docosahexaenoic acid (DHA) and increased IQ among children born prematurely. Preterm children are more likely to have lower IQ scores and cognitive impairments compared with term‐born children. The study, published in the New England Journal of Medicine, followed 323 infants born before 29weeks' gestation, who were given 60mg of DHA/kg/day via enteral or control tube feeding. They were compared with 333 children in the control group, who received an emulsion with no DHA. At 5years of age, children in both groups underwent the Wechsler Preschool and Primary Scale of Intelligence IQ test. “On average, those in the DHA group scored 3.5 points higher on the IQ scale than those in the control group,” lead researcher Dr Jacqueline Gould said. “These very promising results suggest DHA has the potential to improve cognitive performance when administered via emulsion for infants born before 29weeks' gestation.” Although medical advances over the past 30years have increased the survival rates of infants born before 29weeks' gestation, there has been no improvement in their cognitive development. Supplying DHA to these infants while they are in hospital may be one simple intervention that can help boost brain function, the researchers concluded. https://www.nejm.org/doi/10.1056/NEJMoa2206868

Responding to the COVID‐19 pandemic in real time: coordinating a local hospital response using whole genome sequencing of SARS‐CoV‐2

To the Editor: Molecular diagnostics with whole genome sequencing (WGS) of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has been well described as a method to monitor the evolving epidemiology of the coronavirus disease 2019 (COVID‐19) pandemic and coordinate public health responses.1,2 WGS allows for the accurate identification of COVID‐19 variants, which, when combined with accessible diagnostic testing with polymerase chain reaction (PCR) and rapid antigen tests, supports contact tracing and public health action.1,2 Since January 2022, by agreement with the Forensic and Scientific Services reference laboratory, it has been our practice at the Prince Charles Hospital — a tertiary cardiothoracic transplant centre in Brisbane — to sequence all SARS‐CoV‐2 samples of patients requiring hospital admission for COVID‐19. The rapid turnaround times, averaging 36 hours, supported decisions on variant‐specific therapeutics and optimised bed management. The first case of the Omicron BA.2 subvariant detected at our centre was from a sample collected on 4 March 2022 (Box). This was 17days before public announcements of the dominance of the BA.2 strain by the Queensland Chief Health Officer on 21 March 2022.3 With the anticipated increase in local BA.2 cases, we were able to tailor our hospital level response in real time.4 Initially, even though case numbers were low, from an infection prevention and control perspective, we cohorted BA.1 and BA.2 patients separately to mitigate the risk of nosocomial co‐infection. We maintained the workforce and resourcing surge capacity with a second COVID‐19 ward that opened within days of the initial BA.2 case being identified. Furthermore, genome sequencing for COVID‐19 therapeutics resistance mutations led to alterations in clinical management as BA.2 became the dominant local strain, given its lack of susceptibility to sotrovimab. At the hospital and health service level, access to rapid WGS for identification of emerging variants provides the basis for greater infection prevention and control practices, resource and workforce management, and epidemiological monitoring, and carries implications for clinical management and therapeutics. WGS allows for rapid detection and contact tracing of nosocomial outbreaks, supporting identification of chains of transmission within hospitals. This information augments infection prevention and control by identifying gaps in current practice as well as supporting safer health care environmental design that minimises nosocomial transmission. Furthermore, detection of novel variants at the hospital level can help to predict new waves that require allocation of additional staffing and resources. The Australian Government has recognised the evolving role of microbial genomics in public health surveillance but has not yet committed to further development to optimise personalised medicine, hospital care, and therapeutic decision making.5 We strongly advocate for the inclusion of funding for sustainable rapid WGS that provides real‐time results under the Medicare Benefits Schedule. This will expedite Australia's transition to living with COVID‐19 and will allow us to better prepare our health system to manage new and emerging pathogens into the future.

What doctors should consider before prescribing e‐liquids for e‐cigarettes

To the Editor: As nicotine prescribers, we welcome much needed advice for doctors on prescribing nicotine. However, we disagree with several recommendations and concerns raised in the article by Ween and colleagues.1 First, in our experience, the recommended starting nicotine concentration of 18mg/mL is inappropriate for most new users. The most popular devices for transitioning to vaping (pod vapes) have small batteries and require higher nicotine salt concentrations to effectively relieve cravings and withdrawal symptoms, typically 20–50mg/mL.2 On the other hand, 18mg/mL would be too strong for a smoker with low nicotine dependence using a more powerful vape pen or mod device. The concentration of nicotine required should be personalised for each user based on the level of nicotine dependence, device type and puffing topography.3 Second, the authors’ concerns about the toxicity of nicotine are overstated in our view. Nicotine is a toxic poison in its highly concentrated form, but the low concentrations used for vaping carry minimal risk of serious harm, although the long term impact of inhaled nicotine on lung tissue is not yet known.4 Third, Ween and colleagues raise concerns about the addictiveness of nicotine. However, most smokers who switch to vaping are already nicotine‐dependent. Dependence on vaping is generally less than for smoking5 because, in many cases, peak nicotine levels from vaping are lower and nicotine delivery is slower. In vitro and animal studies suggest other chemicals in smoke may also increase dependence, but human studies are lacking.6,7 Fourth, a blanket “3‐month prescription maximum” and an “agreed abstinence plan” do not recognise the diversity of the needs of smokers. Switching to vaping and then ceasing smoking can take many months or years for some smokers. Many continue to vape long term to avoid relapse to smoking or for perceived benefits. Therefore, a more flexible and personalised approach is needed. Last, Ween and colleagues are correct that unknown harms from flavours may appear over time and these need to be carefully monitored. However, flavours are an integral part of the appeal of vaping. Flavours encourage the uptake of vaping by smokers and are associated with higher quit rates.8,9 A recommendation to avoid flavours risks inadvertently increasing smoking.
