Response: Early reports following the initial COVID-19 lockdowns showed huge variation in changes to preterm birth and stillbirth rates, deeming it difficult to understand the pattern worldwide. It was uncertain if the observed variations were due to differences in study design and methodology, immediate impacts of lockdowns or changes in health service utilization. Previous reports from single populations or facilities were unlikely to be representative of the population and could not be compared across populations. Lockdowns affected health, social and economic factors that could lead to reductions in preterm birth rates. Changes in hygiene practices and abruptions to traffic following lockdown led to alterations in non-COVID infections and air pollution, which are known to trigger inflammation and contribute to preterm birth. Given the uncertainty in the earlier reports, we aimed to conduct a rigorous, standardised analysis using high-quality, total-population data from across the world in order to summarize and compare rates across countries. Our large global study included 52 million births between 2015-2020 from 26 countries and represents one of the first large-scale analyses of birth outcomes during the early months of COVID-19.

MedicalResearch.com Interview with: Melanie Clark PhD candidate Murdoch Children's Research Institute The Royal Children's Hospital  blood-pressure-children-hypertensionMedicalResearch.com: What is the background for this study? What are the main findings? Response: Hypertension in children is a growing problem around the world, but when diagnosing hypertension, most of the time blood pressure is only measured in one arm. Our study showed that children can have a blood pressure difference between arms that may be considered significant in a clinical setting. One in four children had a difference between left and right arms that could mean that blood pressure appears normal in one arm, but in the other arm it would be classified as a high blood pressure. This means that if a doctor measures blood pressure in one arm only, a diagnosis of high blood pressure could be missed.

What are the main findings? Response: We are in an era when the price tag of genetic testing by next generation sequencing is becoming a cost-effective and rapid tool for medical diagnosis. The benefit to patients is often a more accurate and early diagnosis. Because we can do genetic analysis on blood or saliva, we don’t need to use more traditional invasive investigations such as biopsies, brain scans or other extensive imaging. We are reaching an unprecedented rate of discovery of new genes for rare disorders which will help solve the mystery for many previously undiagnosed conditions. An incredibly talented international team of researchers, led by the Murdoch Children’s Research Institute (MCRI) identified the underlying cause of a rare brain disorder in children. Together they identified that pathogenic mutations in a gene called NAXD cause severe neurological damage in children after an episode of mild fever or illness. Only six cases have been recorded worldwide and all the children died soon after suffering either a fever or illness. The research paper, ‘NAD(P)HX Dehydratase (NAXD) Deficiency: A Novel Neurodegenerative Disorder Exacerbated By Febrile Illnesses’ is published in the latest edition of the journal, Brain. MCRI lead laboratory researcher Nicole Van Bergen, said the research provides an excellent example of how new genetic testing technologies can be applied to solve the mystery of previously undiagnosed conditions. “By coupling the genetic testing information with sophisticated functional genomic approaches in the laboratory, we were able to pinpoint the exact cause of this disorder,”Dr Van Bergan said. “We used skin cells from patients, as well as other laboratory tools, to work out the gene that caused the children’s early death.

What are the main findings?  Response: Approximately 5% of school-aged children have a communication impairment that affects speech, language, or both. There are many subtypes of speech sound disorders, but the most severe is  (CAS), which impacts sequencing of speech movements. Childhood apraxia of speech  occurs in around 1 in 1000 children. In persistent cases of CAS, speech cannot easily be understood throughout life. Although CAS is rare, unravelling its neurobiological causes is likely to identify brain networks crucial to more common and less severe forms of speech disorders. Here we provide comprehensive speech and neuroimaging data on a large novel family where one parent and 11 children presented with features of childhood apraxia of speech. Brain MRI scanning revealed changes in core parts of the brain responsible for speech production. Even though CAS manifests as a problem with talking, we found disruptions in an underlying pathway of the brain normally associated with language (the meaning and grammar of what we say), rather than speech production. Our findings identify disruption of the dorsal language stream as a novel finding in developmental speech disorders. Overall, our data confirm the early role of this stream in auditory-to-articulation transformations.

MM: Scabies is extremely common. Globally in the region of 100-200 million people are believed to be affected by scabies annually. Recently the WHO has recognised Scabies as a ‘Neglected Tropical Disease’ in response to this burden of disease. There has been increasing interest in using Mass Drug Administration (treating whole communities) as a strategy to control scabies in communities. In order to make this practical countries need an easy mechanism for establishing if scabies is a significant problem in their communities. In general when treating an individual, clinicians would conduct a full body examination to diagnose scabies – however this may not be practical or necessary when making decisions about whether to treat whole communities. DE: Despite the fact that Scabies is a very common condition that causes a great deal of health problems, it has been largely neglected by health, research and funding agencies – but pleasingly, the WHO has now started to take action on scabies control, starting with the recognition of scabies as a "Neglected Tropical Disease"
