- Abstract
Several lifestyle choices made by contact lens wearers can have adverse consequences on ocular health. These include being non-adherent to contact lens care, sleeping in lenses, ill-advised purchasing options, not seeing an eyecare professional for regular aftercare visits, wearing lenses when feeling unwell, wearing lenses too soon after various forms of ophthalmic surgery, and wearing lenses when engaged in risky behaviors (e.g., when using tobacco, alcohol or recreational drugs). Those with a pre-existing compromised ocular surface may find that contact lens wear exacerbates ocular disease morbidity. Conversely, contact lenses may have various therapeutic benefits. The coronavirus disease-2019 (COVID-19) pandemic impinged upon the lifestyle of contact lens wearers, introducing challenges such as mask-associated dry eye, contact lens discomfort with increased use of digital devices, inadvertent exposure to hand sanitizers, and reduced use of lenses. Wearing contact lenses in challenging environments, such as in the presence of dust and noxious chemicals, or where there is the possibility of ocular trauma (e.g., sport or working with tools) can be problematic, although in some instances lenses can be protective. Contact lenses can be worn for sport, theatre, at high altitude, driving at night, in the military and in space, and special considerations are required when prescribing in such situations to ensure successful outcomes. A systematic review and meta-analysis, incorporated within the review, identified that the influence of lifestyle factors on soft contact lens dropout remains poorly understood, and is an area in need of further research. Overall, this report investigated lifestyle-related choices made by clinicians and contact lens wearers and discovered that when appropriate lifestyle choices are made, contact lens wear can enhance the quality of life of wearers.

- Abstract
INTRODUCTION: As routine genomic testing expands, so too does the opportunity to look for additional health information unrelated to the original reason for testing, termed additional findings (AF). Analysis for many different types of AF may be available, particularly to families undergoing trio genomic testing. The optimal model for service delivery remains to be determined, especially when the original test occurs in the acute care setting. METHODS AND ANALYSIS: Families enrolled in a national study providing ultrarapid genomic testing to critically ill children will be offered analysis for three types of AF on their stored genomic data: paediatric-onset conditions in the child, adult-onset conditions in each parent and reproductive carrier screening for the parents as a couple. The offer will be made 3-6 months after diagnostic testing. Parents will have access to a modified version of the Genetics Adviser web-based decision support tool before attending a genetic counselling appointment to discuss consent for AF. Parental experiences will be evaluated using qualitative and quantitative methods on data collected through surveys, appointment recordings and interviews at multiple time points. Evaluation will focus on parental preferences, uptake, decision support use and understanding of AF. Genetic health professionals' perspectives on acceptability and feasibility of AF will also be captured through surveys and interviews. ETHICS AND DISSEMINATION: This project received ethics approval from the Melbourne Health Human Research Ethics Committee as part of the Australian Genomics Health Alliance protocol: HREC/16/MH/251. Findings will be disseminated through peer-review journal articles and at conferences nationally and internationally.

- Abstract
Childhood apraxia of speech (CAS), the prototypic severe childhood speech disorder, is characterized by motor programming and planning deficits. Genetic factors make substantive contributions to CAS aetiology, with a monogenic pathogenic variant identified in a third of cases, implicating around 20 single genes to date. Here we aimed to identify molecular causation in 70 unrelated probands ascertained with CAS. We performed trio genome sequencing. Our bioinformatic analysis examined single nucleotide, indel, copy number, structural and short tandem repeat variants. We prioritised appropriate variants arising de novo or inherited that were expected to be damaging based on in silico predictions. We identified high confidence variants in 18/70 (26%) probands, almost doubling the current number of candidate genes for CAS. Three of the 18 variants affected SETBP1, SETD1A and DDX3X, thus confirming their roles in CAS, while the remaining 15 occurred in genes not previously associated with this disorder. Fifteen variants arose de novo and three were inherited. We provide further novel insights into the biology of child speech disorder, highlighting the roles of chromatin organization and gene regulation in CAS, and confirm that genes involved in CAS are co-expressed during brain development. Our findings confirm a diagnostic yield comparable to, or even higher, than other neurodevelopmental disorders with substantial de novo variant burden. Data also support the increasingly recognised overlaps between genes conferring risk for a range of neurodevelopmental disorders. Understanding the aetiological basis of CAS is critical to end the diagnostic odyssey and ensure affected individuals are poised for precision medicine trials.

- Abstract
We aimed to determine whether SNP-microarray genomic testing of saliva had a greater diagnostic yield than blood for pathogenic copy number variants (CNVs). We selected patients who underwent CMA testing of both blood and saliva from 23,289 blood and 21,857 saliva samples. Our cohort comprised 370 individuals who had testing of both, 224 with syndromic intellectual disability (ID) and 146 with isolated ID. Mosaic pathogenic CNVs or aneuploidy were detected in saliva but not in blood in 20/370 (4.4%). All 20 individuals had syndromic ID, accounting for 9.1% of the syndromic ID sub-cohort. Pathogenic CNVs were large in size (median of 46 Mb), and terminal in nature, with median mosaicism of 27.5% (not exceeding 40%). By contrast, non-mosaic pathogenic CNVs were 100% concordant between blood and saliva, considerably smaller in size (median of 0.65 Mb), and predominantly interstitial in location. Given that salivary microarray testing has increased diagnostic utility over blood in individuals with syndromic ID, we recommend it as a first-tier testing in this group.

- Abstract
GJB2-associated hearing loss (GJB2-HL) is the most common genetic cause of hearing loss in children. However, little is known about the clinical characteristics and early language outcomes in population-oriented samples including children with different degrees of hearing loss. Insight into these characteristics are relevant for the counselling of parents. Our sample consisted of 66 children at approximately 2 years of age (17–32 months) with bilateral hearing loss due to GJB2 from three population-based cohorts in Austria, Australia and the Netherlands. Predictors of early vocabulary, including demographic, audiological, genetic and intervention variables and the role of medical comorbidities and nonverbal cognition were examined. The vocabulary scores of children with GJB2-HL were approximately 0.7 standard deviations (SDs) below the norms of children with typical hearing. Age at access to family-centered early intervention and first-born position among siblings predicted language outcomes, whereas the degree of hearing loss and genetic subtype were not significantly correlated with expressive vocabulary. In children with GJB2-HL, early access to family-centered early intervention significantly affected language outcomes at the age of two.

- Abstract
Errors in mitosis that cause chromosome missegregation lead to aneuploidy and micronucleus formation, which are associated with cancer. Accurate segregation requires the alignment of all chromosomes by the mitotic spindle at the metaphase plate, and any misalignment must be corrected before anaphase is triggered. The spindle is situated in a membrane-free "exclusion zone"; beyond this zone, endomembranes (mainly endoplasmic reticulum) are densely packed. We investigated what happens to misaligned chromosomes localized beyond the exclusion zone. Here we show that such chromosomes become ensheathed in multiple layers of endomembranes. Chromosome ensheathing delays mitosis and increases the frequency of chromosome missegregation and micronucleus formation. We use an induced organelle relocalization strategy in live cells to show that clearance of endomembranes allows for the rescue of chromosomes that were destined for missegregation. Our findings indicate that endomembranes promote the missegregation of misaligned chromosomes that are outside the exclusion zone and therefore constitute a risk factor for aneuploidy.

TONSILLECTOMY , *PEDIATRIC surgery - Abstract
Background: Tonsillectomy is one of the commonest operations in children. Routinely collected national data were used to assess variations in the paediatric tonsillectomy rate across Scotland, and to determine if socio-economic deprivation is the cause. Method: The Scottish Morbidity Records were reviewed for all children (0–16 years) undergoing tonsillectomy from 2001 to 2018. Results: The mean annual tonsillectomy rate was 2.64 per 1000 children. Rates in each health board area varied from 1.24 to 3.9 per 1000. Half of this variation resulted from transfers between regions. There was a 1.75-fold difference between tonsillectomy rates in the most and least deprived population quintiles, but this did not account for the geographical variation. Conclusion: Half the variance in paediatric tonsillectomy rates is associated with children being transferred between regions for treatment. After accounting for this, there is a 1.5-fold difference in rate between health board areas, which is not related to socio-economic deprivation and is currently unexplained. [ABSTRACT FROM AUTHOR]

- Abstract
The diagnosis of children with genetic conditions places a significant economic burden on health care services. The lack of well-defined comparative cohorts has been a limitation of health economic studies comparing first-line genomic sequencing (GS) against traditional approaches. Aim(s): To evaluate utility and cost effectiveness of early GS in pediatric patients with complex monogenic conditions compared to a matched historical cohort. Method(s): Data, including diagnosis rate and investigation costs, were collected in a prospective cohort of 92 pediatric patients who underwent singleton GS over an 18-month period (2016-2017). Inclusion required patients to have two of the following: a condition with high morbidity or mortality, a multi-system disease involving three or more organ systems, or severe limitation of daily function. For comparison, data were collected in a historical patient cohort fulfilling the inclusion criteria who underwent traditional investigations in the two years (2012-2013) prior to the availability of clinical genomic sequencing. Result(s): Genomic sequencing yielded a diagnosis in 42% while traditional investigations yielded a diagnosis in 23% (p = 0.003). 75% of diagnosed patients experienced a change in management, compared to 33% of diagnosed patients who underwent traditional investigations. In the GS cohort, four times fewer invasive investigations were observed. Compared to traditional investigations, singleton genomic sequencing at a cost of $3100 AUD resulted in a mean saving per person of $2780 AUD (95%CI $1585-$3974). Conclusion(s): Early genomic sequencing is highly costeffective while doubling the diagnostic yield of traditional approaches and improving the care of patients with complex genetic conditions.

- Abstract
IMPORTANCE: Genomic newborn screening (gNBS) may optimize the health and well-being of children and families. Screening programs are required to be evidence based, acceptable, and beneficial. OBJECTIVES: To identify what has been discovered following the reporting of the first gNBS pilot projects and to provide a summary of key points for the design of gNBS. EVIDENCE REVIEW: A systematic literature review was performed on April 14, 2021, identifying 36 articles that addressed the following questions: (1) what is the interest in and what would be the uptake of gNBS? (2) what diseases and genes should be included? (3) what is the validity and utility of gNBS? and (4) what are the ethical, legal, and social implications? Articles were only included if they generated new evidence; all opinion pieces were excluded. FINDINGS: In the 36 articles included, there was high concordance, except for gene disease inclusion, which was highly variable. Key findings were the need for equitable access, appropriate educational materials, and informed and flexible consent. The process for selecting genes for testing should be transparent and reflect that parents value the certainty of prediction over actionability. Data should be analyzed in a way that minimizes uncertainty and incidental findings. The expansion of traditional newborn screening (tNBS) to identify more life-threatening and treatable diseases needs to be balanced against the complexity of consenting parents of newborns for genomic testing as well as the risk that overall uptake of tNBS may decline. The literature reflected that the right of a child to self-determination should be valued more than the possibility of the whole family benefiting from a newborn genomic test. CONCLUSIONS AND RELEVANCE: The findings of this systematic review suggest that implementing gNBS will require a nuanced approach. There are gaps in our knowledge, such as the views of diverse populations, the capabilities of health systems, and health ec

- Abstract
Decisions about genetic testing have traditionally been based on clinical utility and cost, but personal utility is increasingly recognized when assessing the value of testing. Whole exome sequencing (WES) was offered to a population cohort of 106 infants diagnosed with congenital hearing loss. Parents could choose to receive results relating to hearing loss only or also learn additional information about childhood-onset conditions (medically nonactionable and/or actionable). This study aimed to quantify the personal utility of WES for parents after a diagnosis of hearing loss in their child. Parents completed surveys pretest (63/106), after hearing loss results (52/106) and after receiving additional information (47/72). Open-ended responses from all three surveys (N = 67) were analyzed using inductive content analysis. Answers to questions regarding the value of sequencing to parents were analyzed and collated. Parents placed high value on diagnostic WES for hearing loss but had different perspectives on the personal utility of additional information. Diagnostic results provided certainty while the choice to learn additional information about childhood-onset disorders was associated with empowerment. WES also represented an opportunity to promote their child's best interests. Results provide insights into the utility of WES for the indication of congenital deafness and for genomic newborn screening broadly.

- Abstract
OBJECTIVES/HYPOTHESIS: To assess the relative cost-effectiveness of exome sequencing for isolated congenital deafness compared with standard care. STUDY DESIGN: Incremental cost-effectiveness and cost-benefit analyses were undertaken from the perspective of the Australian healthcare system using an 18-year time horizon. METHODS: A decision tree was used to model the costs and outcomes associated with exome sequencing and standard care for infants presenting with isolated congenital deafness. RESULTS: Exome sequencing resulted in an incremental cost of AU$1,000 per child and an additional 30 diagnoses per 100 children tested. The incremental cost-effectiveness ratio was AU$3,333 per additional diagnosis. The mean societal willingness to pay for exome sequencing was estimated at AU$4,600 per child tested relative to standard care, resulting in a positive net benefit of AU$3,600. Deterministic and probabilistic sensitivity analyses confirmed the cost-effectiveness of exome sequencing. CONCLUSIONS: Our findings demonstrate the cost-effectiveness of exome sequencing in congenital hearing loss, through increased diagnostic rate and consequent improved process of care by reducing or ceasing diagnostic investigation or facilitating targeted further investigation. We recommend equitable funding for exome sequencing in infants presenting with isolated congenital hearing loss. LEVEL OF EVIDENCE: N/A. Laryngoscope, 131:E2371-E2377, 2021.

- Abstract
Purpose: Cost-effectiveness evaluations of first-line genomic sequencing (GS) in the diagnosis of children with genetic conditions are limited by the lack of well-defined comparative cohorts. We sought to evaluate the cost-effectiveness of early GS in pediatric patients with complex monogenic conditions compared with a matched historical cohort. Method(s): Data, including investigation costs, were collected in a prospective cohort of 92 pediatric patients undergoing singleton GS over an 18-month period (2016-2017) with two of the following: a condition with high mortality, multisystem disease involving three or more organs, or severe limitation of daily function. Comparative data were collected in a matched historical cohort who underwent traditional investigations in the years 2012-2013. Result(s): GS yielded a diagnosis in 42% while traditional investigations yielded a diagnosis in 23% (p = 0.003). A change in management was experienced by 74% of patients diagnosed following GS, compared with 32% diagnosed following traditional investigations. Singleton GS at a cost of AU$3100 resulted in a mean saving per person of AU$3602 (95% confidence interval [CI] AU$2520-4685). Cost savings occurred across all investigation subtypes and were only minimally offset by clinical management costs. Conclusion(s): GS in complex pediatric patients saves significant costs and doubles the diagnostic yield of traditional approaches.Copyright © 2020, American College of Medical Genetics and Genomics.

- Abstract
Congenital hearing impairment (HI) is the most common sensory impairment and can be isolated or part of a syndrome. Diagnosis through newborn hearing screening and management through early intervention, hearing aids and cochlear implantation is well established in the Australian setting; however understanding the genetic basis of congenital HI has been missing. This population-derived cohort comprised infants with moderate-profound bilateral HI born in the 2016-2017 calendar years, detected through newborn hearing screening. Participants were recruited through an integrated paediatric, otolaryngology and genetics HI clinic and offered whole exome sequencing (WES) on a HiSeq4000 or NextSeq500 (Illumina) platform with a targeted average sequencing depth of 100x and chromosome microarray on the Illumina Infinium core exome-24v1.2 platform. Of those approached, 68% (106/156) consented to participate. The rate of genetic diagnosis was 56% (59/106), significantly higher than standard of care (GJB2/6 sequencing only), 21% (22/106). There were clinical implications for the 106 participants: 36% required no further screening, 9% had tailored screening initiated, 2% were offered treatment and 4% had informed care for a complex neurodevelopmental syndrome. WES in this cohort demonstrates the range of diagnoses associated with congenital HI and confirms the genetic heterogeneity of congenital HI. The high diagnostic yield and clinical implications emphasises the need for genomic sequencing to become standard of care.Copyright © 2019, The Author(s), under exclusive licence to European Society of Human Genetics.

- Abstract
PURPOSE: Genomic newborn screening raises practical and ethical issues. Evidence is required to build a framework to introduce this technology safely and effectively. We investigated the choices made by a diverse group of parents with newborns when offered tiered genomic information from exome sequencing. METHODS: This population-derived cohort comprised infants with congenital deafness. Parents were offered exome sequencing and choice regarding the scope of analysis. Options were choice A, diagnostic analysis only; choice B, diagnostic analysis plus childhood-onset diseases with medical actionability; or choice C, diagnostic analysis plus childhood-onset diseases with or without medical actionability. RESULTS: Of the 106 participants, 72 (68%) consented to receive additional findings with 29 (27.4%) selecting choice B and 43 (40.6%) opting for choice C. Family size, ethnicity, and age of infant at time of recruitment were the significant predictors of choice. Parents who opted to have additional findings analysis demonstrated less anxiety and decisional conflict. CONCLUSIONS: These data provide evidence from a culturally diverse population that choice around additional findings is important and the age of the infant when this choice is offered impacts on their decision. We found no evidence that offering different levels of genomic information to parents of newborns has a negative psychological impact.

- Abstract
Internationally, the practice of offering additional findings (AFs) when undertaking a clinically indicated genomic test differs. In the USA, the recommendation is to include analysis for AFs alongside diagnostic analysis, unless a patient opts-out, whereas European and Canadian guidelines recommend opt-in models. These guidelines all consider the offer of AFs as an activity concurrent with the offer of diagnostic testing. This paper describes a novel two-step model for managing AFs within the healthcare system in Victoria, Australia and presents the study protocol for its evaluation. Adults who have received results of diagnostic whole exome sequencing undertaken within the healthcare system are invited to attend a genetic counseling appointment to consider reanalysis of their stored genomic data for AFs. The evaluation protocol addresses uptake, decision-making, understanding, counseling challenges, and explores preferences for future models of care. Recruitment commenced in November 2017 and will cease when 200 participants have been approached. When the study is concluded, the evaluation results will contribute to the evidence base guiding approaches to counseling and models of care for AFs.Copyright © 2019 National Society of Genetic Counselors.

- Abstract
Background: Exome sequencing has the potential to be used in newborn screening and international research is investigating the feasibility of this approach. It is not yet clear how parents will respond to the genomic newborn screening in their children. Aim(s): To explore parents' interest in genomic testing and what factors influence decision making about the scope of results received. Method(s): Families that consented for WES to identify the cause of hearing loss in their child were eligible. They could choose additional analysis of selected childhood onset genetic conditions unrelated to hearing loss. Families were provided with a decision aid and a genetic counseling session over two sites. Participants could choose to receive results for childhood onset genetic conditions with a known treatment or intervention pathway (Choice B), or all conditions, some of which do not have a known treatment or intervention pathway (Choice C). The families' completed evaluation surveys regarding their decision making post recruitment and at return of results. Result(s): Of the 107 patients who consented for WES, 64% opted to receive additional findings. Of those, 42% selected Choice B and 58% Choice C. Decisional conflict was lower among those who chose additional findings. The rate of uptake is significantly different between the two recruitment sites. Discussion(s): A majority of parents are requesting additional information. Analysis of genetic counseling notes and patient demographics will provide insight into parents' decision making. Conclusion(s): The results of this project illustrate the importance of providing choice around additional findings in genomic testing.

- Abstract
Genomics has the potential to be a powerful newborn screening tool, this is being investigated internationally. Genomic tests are increasingly available in Australia and additional findings can be analyzed and inform future health. This study aimed to explore parents' interest in receiving additional findings from genomic testing and determine factors influencing decision-making about the scope of results desired. Families that consented for exome sequencing to investigate deafness in their child were eligible. They were provided with a decision aid and a genetic counseling session. Participants could choose (A) no additional results; (B) additional results for childhood onset genetic conditions with a known treatment; or (C) additional results for childhood onset conditions with or without a known treatment. All families completed surveys about their decision-making at recruitment and after return of results. One hundred and six families participated, of which 72 (68%) chose to receive additional findings: 29 (27%) opted for choice B and 43 (41%) opted for choice C. Decisional conflict and anxiety levels were lower in those who chose to receive additional findings but similar between groups B and C. Intolerance of uncertainty was highest in the choice A group. Eighty percent of participants used the decision aid and 74% made a decision before their appointment however 23% consented to a different option post genetic counseling. Four participants had additional results returned, of which two required further management. This study highlights the interest in additional findings from genomic sequencing and emphasizes the importance of choice as families desire different levels of information.

- Abstract
Background: The Melbourne Genomics Health Alliance is establishing systems and producing evidence to guide incorporation of genomics into the Victorian healthcare system. Through one of its clinical flagship projects, the Alliance is offering WES to families who have an infant with moderate to profound bilateral hearing loss born in 2016 or 2017. Aim(s): The aim of this project is to define the genetic etiology of congenital hearing loss, streamline the care of affected children and explore parents' interest in genomic testing. Method(s): Families who have an eligible child are identified by the statewide Victorian Infant Hearing Screening Program (VIHSP). Participants are offered pediatrician-run hearing clinic appointment and genetics appointment. WES with targeted gene analysis is performed in conjunctionwith microarray. Result(s): 70% of eligible participants consented to WES. Of the 107 patients recruited, 52 results have been issued to date. The rate of diagnosis is 67%; 33% have connexin mutations, 17% have another non-syndromic deafness gene identified, 17% have a syndromic diagnosis. Microarray has contributed to 10% of diagnoses when combined with WES results. An additional 34% of participants have received a diagnosis using WES over our centre's usual investigation methods of connexin testing and microarray. Discussion(s): Understanding the genetic etiology for infants with congenital hearing loss provides important information for families regarding prognosis, reproductive risk and screening for associated health problems in their child. Conclusion(s): This study provides a comprehensive understanding of the genetic etiology of congenital hearing loss over this two year period.

- Abstract
Permanent hearing loss affects 1-3 per 1000 children in Australia. Universal hearing screening of neonates has facilitated early diagnosis and access to hearing devices and early intervention services. Despite this clinical management and investigation of newly diagnosed infants is highly variable. The aim is to provide consensus recommendations for the investigation and clinical management of children with hearing loss for geneticists, pediatricians, otolaryngolo-gists and general practitioners. The Childhood Hearing Australasian Medical Professionals (CHAMP) network was established in 2016 to improve care for hearing-impaired children in Australasia. A working group of 15 members held round-table discussions, examined existing guidelines and completed literature reviews to create a set of recommendations. Members votedonthe grade and strengthofrec-ommendations using NHMRC guidelines. Recommendations are presented in three tiers: (1) First line investigations for non-syndromic hearing loss, (2) Additional investigations based on clinical presentation, and (3) Investigations to consider if tier 1 and 2 investigations are negative. In addition to detailed history taking and examination, all children with congenital hearing loss should have CMV testing, brain MRI, ophthalmology assessment and family audiograms. Children with bilateral SNHL should be offered genetic testing after adequate genetic counseling, with connexin/GJB2 testing as first-line and chromosome microarray as second-line. Where available, genomic testing (exome or deafness panel) should be considered in children with bilateral SNHL, and may reduce the need for other investigations. The role of genetic testing in unilateral loss is limited and should be guided by clinical presentation.

- Abstract
Purpose: This systematic review synthesized evidence supporting interventions aimed at mitigating cognitive bias associated with the decision-making of social work professionals. Methods: A systematic search was conducted within 10 social services and health-care databases. Review authors independently screened studies in duplicate against prespecified inclusion criteria, and two review authors undertook data extraction and quality assessment. Results: Four relevant studies were identified. Because these studies were too heterogeneous to conduct meta-analyses, results are reported narratively. Three studies focused on diagnostic decisions within mental health and one considered family reunification decisions. Two strategies were reportedly effective in mitigating error: a nomogram tool and a specially designed online training course. One study assessing a consider-the-opposite approach reported no effect on decision outcomes. Conclusions: Cognitive bias can impact the accuracy of clinical reasoning. This review highlights the need for research into cognitive bias mitigation within the context of social work practice decision-making.

- Abstract
This qualitative review explores how established citizen science models can inform and support meaningful engagement of public in health research in Australia. In particular, with the growth in participatory health research approaches and increasing consumer participation in contributing to this research through digital technologies, there are gaps in our understanding of best practice in health and biomedical citizen science research to address these paradigm shifts. Notable gaps are how we might more clearly define the parameters of such research and which citizen science models might best support digitally-enabled participation falling within these. Further work in this area is expected to lead to how established citizen science methods may help improve the quality of and the translation of public engagement in health research.

BACKGROUND: Previous studies indicate increased prevalences of suicidal ideation, suicide attempts, and completed suicide in Huntington's disease (HD) compared with the general population. This study investigates correlates and predictors of suicidal ideation in HD.METHODS: The study cohort consisted of 2106 HD mutation carriers, all participating in the REGISTRY study of the European Huntington's Disease Network. Of the 1937 participants without suicidal ideation at baseline, 945 had one or more follow-up measurements. Participants were assessed for suicidal ideation by the behavioural subscale of the Unified Huntington's Disease Rating Scale (UHDRS). Correlates of suicidal ideation were analyzed using logistic regression analysis and predictors were analyzed using Cox regression analysis.RESULTS: At baseline, 169 (8.0%) mutation carriers endorsed suicidal ideation. Disease duration (odds ratio [OR]=0.96; 95% confidence interval [CI]: 0.9-1.0), anxiety (OR=2.14; 95%CI: 1.4-3.3), aggression (OR=2.41; 95%CI: 1.5-3.8), a previous suicide attempt (OR=3.95; 95%CI: 2.4-6.6), and a depressed mood (OR=13.71; 95%CI: 6.7-28.0) were independently correlated to suicidal ideation at baseline. The 4-year cumulative incidence of suicidal ideation was 9.9%. Longitudinally, the presence of a depressed mood (hazard ratio [HR]=2.05; 95%CI: 1.1-4.0) and use of benzodiazepines (HR=2.44; 95%CI: 1.2-5.0) at baseline were independent predictors of incident suicidal ideation, whereas a previous suicide attempt was not predictive.LIMITATIONS: As suicidal ideation was assessed by only one item, and participants were a selection of all HD mutation carriers, the prevalence of suicidal ideation was likely underestimated.CONCLUSIONS: Suicidal ideation in HD frequently occurs. Assessment of suicidal ideation is a priority in mutation carriers with a depressed mood and in those using benzodiazepines.

- Abstract
Introduction The aetiology of congenital hearing loss is heterogeneous, and in many infants a genetic cause is suspected. Parents face a diagnostic odyssey when searching for a cause of their infant's hearing loss. Through the Melbourne Genomics Health Alliance, a prospective cohort of infants will be offered whole-exome sequencing (WES) with targeted analysis in conjunction with chromosome microarray to determine the genetic causes of congenital hearing loss. Parents will also be offered the opportunity to receive additional results from their infant's WES. Methods Eligible infants will be identified through the Victorian Infant Hearing Screening Program and offered an appointment in a paediatrician-run clinic, a genetics assessment and enrolment in the Victorian Childhood Hearing Impairment Longitudinal Databank. If parents consent to WES, genes causing deafness will be analysed and they can choose to obtain additional findings. For the additional results component, a modified laboratory protocol has been designed for reporting of results in the absence of a relevant phenotype. Parents' experience of being offered WES will be evaluated using surveys. Discussion This project will provide descriptive analysis of the genetic aetiology of congenital hearing loss in this cohort and May provide data on genotype-phenotype correlations.

The cause of Huntington disease (HD) is a polyglutamine repeat expansion of more than 36 units in the huntingtin protein, which is inversely correlated with the age at onset of the disease. However, additional genetic factors are believed to modify the course and the age at onset of HD. Recently, we identified the V471A polymorphism in the autophagy-related gene ATG7, a key component of the autophagy pathway that plays an important role in HD pathogenesis, to be associated with the age at onset in a large group of European Huntington disease patients. To confirm this association in a second independent patient cohort, we analysed the ATG7 V471A polymorphism in additional 1,464 European HD patients of the "REGISTRY" cohort from the European Huntington Disease Network (EHDN). In the entire REGISTRY cohort we could not confirm a modifying effect of the ATG7 V471A polymorphism. However, analysing a modifying effect of ATG7 in these REGISTRY patients and in patients of our previous HD cohort according to their ethnic origin, we identified a significant effect of the ATG7 V471A polymorphism on the HD age at onset only in the Italian population (327 patients). In these Italian patients, the polymorphism is associated with a 6-years earlier disease onset and thus seems to have an aggravating effect. We could specify the role of ATG7 as a genetic modifier for HD particularly in the Italian population. This result affirms the modifying influence of the autophagic pathway on the course of HD, but also suggests population-specific modifying mechanisms in HD pathogenesis.

- Abstract
INTRODUCTION: The aetiology of congenital hearing loss is heterogeneous, and in many infants a genetic cause is suspected. Parents face a diagnostic odyssey when searching for a cause of their infant's hearing loss. Through the Melbourne Genomics Health Alliance, a prospective cohort of infants will be offered whole-exome sequencing (WES) with targeted analysis in conjunction with chromosome microarray to determine the genetic causes of congenital hearing loss. Parents will also be offered the opportunity to receive additional results from their infant's WES. METHODS: Eligible infants will be identified through the Victorian Infant Hearing Screening Program and offered an appointment in a paediatrician-run clinic, a genetics assessment and enrolment in the Victorian Childhood Hearing Impairment Longitudinal Databank. If parents consent to WES, genes causing deafness will be analysed and they can choose to obtain additional findings. For the additional results component, a modified laboratory protocol has been designed for reporting of results in the absence of a relevant phenotype. Parents' experience of being offered WES will be evaluated using surveys. DISCUSSION: This project will provide descriptive analysis of the genetic aetiology of congenital hearing loss in this cohort and may provide data on genotype-phenotype correlations. Additionally, choices regarding additional findings will be analysed. Participants will represent a diverse cross section of the population, increasing the ability to generalise results beyond the study group. Evaluation surveys will allow analysis of preferences around counselling, usefulness of a decision aid and adequacy of information provision.

Low–cost housing which has been disposed of by private owners is extremely difficult for conveyancers to register. The law as it stands is often incapable of giving effect to the business transactions of the poor, thereby creating insecurity of tenure nationwide. The Land Titles Adjustment Act 111 of 1993 is currently the only legislation capable of dealing with this impasse. The Overstrand Municipality has provided the staff and infrastructure to run a pilot project under the Act, for which it is awaiting confirmation from the Department of Rural Development and Land Reform. This article discusses the legal issues arising and the potential of such an initiative to provide consumer protection for the low–literate and other vulnerable holders of rights.

- Abstract
The solid solution Cs2-xRbxSnCu3F 12 (x = 0, 0.5, 1.0, 1.5) has been investigated crystallographically between 100 and 300 K using synchrotron X-ray powder diffraction and, in the case of x = 0, neutron powder diffraction. For Cs2SnCu 3F12 (x = 0), there is a structural transition from the previously reported room temperature rhombohedral symmetry (R3m) to monoclinic (P21/n) symmetry at 170 K. This transformation is repeated for the x = 0.5 composition, but with an increased transition temperature of 250 K. For x = 1.0 the monoclinic phase is found at 300 K, suggesting that the transition temperature is increased even further. For x = 1.5 a different behaviour, more akin to that previously reported for Rb2SnCu3F 12, is found: a single phase transition between rhombohedral symmetry (R3) and triclinic symmetry (P1) is found at 280 K. In agreement with previous single crystal studies, Cs2SnCu3F12 powder exhibits strong antiferromagnetic interactions (Θ ~ -268 K) and long-range magnetic order at TN ~ 19.3 K. The finite magnetic moment observed for T < TN might be explained by a Dzyaloshinskii-Moriya interaction, due to the lowering of symmetry from rhombohedral to monoclinic, which was not suggested in the earlier single crystal study.

- Abstract
Aim Congenital chylothorax is a rare but significant neonatal entity with major morbidity and mortality. The study aims to describe the related associations, management and outcomes of this condition in neonates. Methods This is a retrospective case series of all cases of congenital chylothorax admitted to a tertiary neonatal centre in the last 15 years. Results Ten cases of congenital chylothorax were identified. Eight infants were diagnosed antenatally and three infants had antenatal pleural drainage. Most infants were ventilated at birth and required immediate pleurocentesis. Post-natal management included drainage of fluid, ventilation, albumin replacement, octreotide and dietary modification with medium-chain triglyceride-enriched formula. Five infants had chromosomal aberrations identified, while a further two had dysmorphic features not substantiated with routine genetic testing. Noonan's syndrome was the single most common underlying genetic diagnosis. Associated anomalies and malformations were present in 80% of the cohort. There were two deaths in the series, both in infants with multiple co-morbidities. Conclusions Congenital chylothorax is a rare condition with overall prevalence of less than a case per year in our experience. Majority of infants had associated chromosomal anomalies and significant co-morbidities needing prolonged intensive care. © 2013 The Authors.

- Abstract
We report a case of a neonate who was shown with routine chromosome analysis on peripheral blood lymphocytes to have full monosomy 21. Further investigation on fibroblast cells using conventional chromosome and FISH analysis revealed two additional mosaic cell lines; one is containing a ring chromosome 21 and the other a double ring chromosome 21. In addition, chromosome microarray analysis (CMA) on fibroblasts showed a mosaic duplication of chromosome region 21q11.2q22.13 with approximately 45% of cells showing three copies of the proximal long arm segment, consistent with the presence of a mosaic ring chromosome 21 with ring instability. The CMA also showed complete monosomy for an 8.8 Mb terminal segment (21q22.13q22.3). Whilst this patient had a provisional clinical diagnosis of trisomy 21, the patient also had phenotypic features consistent with monosomy 21, such as prominent epicanthic folds, broad nasal bridge, anteverted nares, simple ears, and bilateral overlapping fifth fingers, features which can also be present in individuals with Down syndrome. The patient died at 4.5 months of age. This case highlights the need for additional studies using multiple tissue types and molecular testing methodologies in patients provisionally diagnosed with monosomy 21, in particular if detected in the neonatal period.
