Gibson M, Leske S, Ward R, Weir B, Russell K, Kolves K. Aboriginal and Torres Strait Islander youth suicide mortality and previous mental health, suicidality and service use in Queensland, Australia, from 2001 to 2021. J Affect Disord 2024; 354:55-61. [PMID: 38484672 DOI: 10.1016/j.jad.2024.03.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 02/25/2024] [Accepted: 03/04/2024] [Indexed: 04/15/2024]
Abstract
BACKGROUND The current study aimed to compare current suicide rates, trends, previous treatment, suicidality and mental health diagnoses for First Nations and non-Indigenous young people who died by suicide. METHODS Age-specific suicide rates (ASSRs) were calculated per 100,000 persons/year using suicides aged 10-19 years in the Queensland Suicide Register. Rate Ratios (RRs) and 95 % CIs compared ASSRs for First Nations and non-Indigenous youth dying by suicide in Queensland, Australia, from 2001 to 2018. Risk ratios (RiskR) with 95 % CIs compared characteristics between First Nations and non-Indigenous youth suicides. Joinpoint regression was used to identify any changes in trends and annual percentage change (APC) in suicides with 95 % CIs. RESULTS The First Nations youth ASSR was 24.71 deaths per 100,000 persons/year, 4.5 times the non-Indigenous ASSR (95 % CI = 3.74-5.38, p < 0.001). Both non-Indigenous and First Nations suicide trends were stable with no joinpoints (APC: 0.3 %, 95 % CI: -1.6-2.2, p = 0.78; APC: 0.9 %, 95 % CI: -0.2-2.1, p = 0.11). Less than a quarter (23.9 %) of First Nations young people had ever received mental health treatment, significantly fewer than non-Indigenous youth (RiskR = 0.80, 95 % CI = 0.71-0.90, p < 0.001). Similarly, in the three months preceding their death, only 14.5 % of First Nations young people had received mental health treatment (RiskR = 0.89, 95 % CI = 0.83-97, p = 0.015). LIMITATIONS Reported mental illness, suicidality and help-seeking could be underreported due to concealment from family or police. CONCLUSIONS The current study finds no change in the gap between the First Nations and Non-Indigenous youth suicide rates nor evidence of decrease in the First Nations youth suicide rate. There is a need for alternative approaches to Indigenous youth suicide prevention, such as assertive outreach models outside of traditional triage and mental health systems to proactively build trusting relationships with young people in communities to identify young people needing support.

Abstract
CASE HISTORY Two clusters of mortality among endangered tūturuatu/tchūriwat'/shore plover (Thinornis novaeseelandiae) have occurred at captive breeding facilities around New Zealand in recent years. In the first, four chicks died at Pūkaha National Wildlife Centre (Mount Bruce, NZ) in February 2016, and in the second five adult birds at the Cape Sanctuary (Cape Kidnappers, NZ) died in 2022. CLINICAL FINDINGS In 2016, four chicks were noted to become weak, have increased vocalisations and closed eyes prior to death. The remaining chicks were treated for 5 days with amoxycillin/clavulanate orally twice daily. Water containers and brooders were cleaned and disinfected with chlorhexidine. No further mortality was seen.In the 2022 cluster, three adult breeding birds died acutely and five others showed inappetence, weight loss and diarrhoea approximately 10 days after heavy rains flooded the local river. The five birds were treated with amoxycillin/clavulanate orally twice daily and oral fluids for 5 days. Two birds died and three survived. No breeding occurred in the aviaries in the following season. PATHOLOGICAL FINDINGS In 2016, the chicks showed pulmonary changes ranging from congestion and oedema to heterophilic inflammation consistent with septicaemia.In 2022, the adult birds showed proliferation of bacteria in the distal small intestine associated with mucosal ulceration and heterophilic infiltration. Acid-fast staining of the caecal contents in one bird showed organisms consistent with Cryptosporidium spp. LABORATORY FINDINGS Aerobic bacterial cultures of the lung and liver of two affected chicks carried out in 2016 showed heavy growth of Plesiomonas shigelloides. The same organism was cultured from water trays and holding tanks containing water boatmen (Sigara arguta) on which the chicks were fed.In 2022, cultures from the livers of three dead birds each showed a mixed bacterial growth with differing dominant organisms (Aeromonas sobria, Hafnia alvei, Citrobacter freundii and an Enterococcus sp.). PCR and sequencing confirmed Cryptosporidium parvum in the caecum of one bird. Fresh faeces from 24 breeding birds from the captive breeding facilities were negative by PCR for Cryptosporidium spp.The captive breeding facilities obtain water for the aviaries and aquatic invertebrates to feed to the chicks from local freshwater sources. Water quality testing at the Cape Sanctuary revealed concentrations of faecal indicator bacteria in excess of safe drinking water guidelines, with peaks following heavy rainfall. CLINICAL RELEVANCE Fluctuations in water quality associated with mammalian faecal bacteria can adversely affect bird health and impact on captive rearing of endangered wildlife.

Abstract
Continuous approaches to measuring bilingualism have recently emerged as a means of understanding individual variation in language abilities. To date, limited information is available to assist in understanding the language abilities of bilingual children with Down syndrome (DS), who are specifically known to have a large variation in linguistic outcomes. Group studies in this population report that children exposed to two languages do not differ from their monolingual counterparts after considering age and non-verbal cognitive abilities, although no study to date has examined the relationship between the amount of exposure to one language and the linguistic abilities in the other language within this population. This study sought to identify whether exposure to an additional language, specifically Welsh, predicted linguistic abilities in the majority language, in this case, English. Sixty-five children between the ages of 5;5-16;9 who had varied linguistic experiences completed a range of cognitive and linguistic assessments. Results from hierarchical regression analyses show that the amount of exposure to Welsh had no impact on language abilities in English, after controlling for non-verbal cognitive abilities, short-term memory and socioeconomic status. This demonstrates that exposure to an additional language does not have a negative impact on language development, a finding that has important clinical and educational implications.

Food Insecurity, Food Assistance, and Psychological Distress among University Students: Cross-Sectional Survey Western Australia, 2020. Nutrients 2023; 15:nu15112431. [PMID: 37299396 DOI: 10.3390/nu15112431] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 05/17/2023] [Accepted: 05/21/2023] [Indexed: 06/12/2023] Open
Abstract
University students have been identified as a population sub-group vulnerable to food insecurity. This vulnerability increased in 2020 due to the COVID-19 pandemic. This study aimed to assess factors associated with food insecurity among university students and the differences between students with and without children. A cross-sectional survey of (n = 213) students attending one university in Western Australia measured food insecurity, psychological distress, and socio-demographic characteristics. Logistic regression analyses were conducted to identify factors associated with food insecurity. Forty-eight percent of students who responded to the survey had experienced food insecurity in 2020. International students who were studying in Australia were nine times more likely to experience food insecurity than domestic students (AOR = 9.13; 95% CI = 2.32-35.97). International students with children were more likely to experience food insecurity than international students without children (p < 0.001) and domestic students with (p < 0.001) or without children (p < 0.001). For each unit increase in depression level, the likelihood of experiencing food insecurity increased (AOR = 1.62; 95% CI = 1.12-2.33). Findings show a higher prevalence of food insecurity among international university students and students with children during the COVID-19 pandemic and that food insecurity was associated with higher levels of psychological distress. These findings highlight the need for targeted interventions to mitigate the risk of food insecurity among Australian university students, particularly among international students, students with children, and those experiencing psychological distress.

Abstract
INTRODUCTION Alcohol-related brain damage (ARBD) is an umbrella term referring to the neurocognitive impairments caused by excessive and prolonged alcohol use and the associated nutritional deficiencies. This study evaluated the outcomes of an online research-informed training program for ARBD which aimed to improve client outcomes by promoting support staff's awareness and confidence in working with clients who may have (or who are at risk of developing) the condition. METHODS Staff working within a large non-governmental non-profit housing organisation (n = 883) enrolled in the training program. Questionnaires were used pre- and post-training to collect self-reported awareness of ARBD and confidence in supporting individuals with the condition. Semi-structured interviews were conducted with 27 staff members approximately 10 weeks post-completion of the program. Interviews were audio-recorded, transcribed verbatim and analysed by employing qualitative content analysis. RESULTS Findings from the questionnaires indicated a significant increase in all measures after completing the training program. Three main themes were developed based on the interview data: changes to awareness and understanding; professional practice; and training-specific characteristics. Participants reported changes in their ability to identify potential service users with ARBD and confidence in doing so. DISCUSSION AND CONCLUSION Our findings demonstrate that online training programs can be effective in improving support staff's ability to identify ARBD, potentially leading an increase in signposting service users to relevant services. The research-informed nature of the training demonstrates that translating research findings directly to frontline workers can have a substantial impact and may improve outcomes for this client group.

Abstract
Joint infections are rare in pediatrics, and those caused by Bacillus cereus are practically unheard of. In this case report, we examine a singular case of B. cereus septic arthritis in a child, with the purpose of educating clinicians on the presentation, inpatient and outpatient management, and clinical outcome. We report the case of a previously healthy pediatric patient who presented to the emergency department with symptoms of septic arthritis of the left knee. The orthopedics team performed arthroscopy and debridement, and the synovial fluid culture grew B. cereus. To our knowledge, this is the first case report on septic arthritis caused by B. cereus in the pediatric population. The treatment protocol consisted of intravenous vancomycin for one week, followed by three weeks of oral ciprofloxacin therapy. The patient had an excellent clinical outcome and returned to normal mobility without limitations. Despite being ubiquitous in the environment, extra-intestinal B. cereus infection is exceedingly rare in immunocompetent individuals. It is so rare, in fact, that it is often dismissed as a lab contaminant. In this case, we demonstrated that cooperation between multiple disciplines offers good clinical outcomes for rare infections, especially those in pediatrics.

Abstract
Project-based learning (PBL) has long been recognized as an effective way to teach complex biology concepts. However, not all institutions have the resources to facilitate effective project-based coursework for students. We have developed a framework for facilitating PBL using remote-controlled internet-connected microscopes. Through this approach, one lab facility can host an experiment for many students around the world simultaneously. Experiments on this platform can be run on long timescales and with materials that are typically unavailable to high school classrooms. This allows students to perform novel research projects rather than just repeating standard classroom experiments. To investigate the impact of this program, we designed and ran six user studies with students worldwide. All experiments were hosted in Santa Cruz and San Francisco, California, with observations and decisions made remotely by the students using their personal computers and cellphones. In surveys gathered after the experiments, students reported increased excitement for science and a greater desire to pursue a career in STEM. This framework represents a novel, scalable, and effective PBL approach that has the potential to democratize biology and STEM education around the world.

Abstract
Abstract
Introduction/Background
Patients attend rheumatology daycare either for regular infusions or one episode depending on their treatment. A typical day for a child would involve observations, having a cannula put in and having the infusion before returning home. Due to the COVID-19 pandemic, there had been some changes to the day care pathway in our hospital including: only one parent being allowed to attend with their child; a strict timing schedule; COVID-19 testing prior to attending appointments. We felt it is vital to know the young person and the family’s perspectives of their experience at day care.
Description/Method
A special study module (SSM) medical student conducted a feedback survey over a 2 month period (December 2021 and January 2022). The aims and objectives were focused on the following: Whether the patients are receiving an appropriate level of care to optimise their experience at day-care.was their treatment given in a timely manner?Were there any delays, if so the reasons and actions taken to mitigate.
2 questionnaires were used, one for the patient and one for the parent/carers. The questionnaires were provided to the patient/carers during their admission by the admitting nursing staff. The medical student collected the questionnaires at the end of the day.
Discussion/Results
39 patients attended the daycare during this period. 9 completed questionnaires were received.
• Feedback from parents/carers:
- Carers (100%) said they were happy with how they had appointment dates and most appointments took their availability and preferences into consideration. Due to COVID, families were notified of their appointment time only one day prior; this was highlighted as an area for improvement to ensure enough notice for the appointment time.
- All parents (100%) agreed that they received enough information regarding their child’s appointment at daycare and this was delivered in an understandable manner.
- 77.8% (7 out of 9) of parents did not experience long waiting times at their appointment. 22.2% (2 out of 9) parents said there were long waiting times at their appointment, and they were made aware of the reasons regarding the wait. The main reasons highlighted was busy ward with lots of patients.
- 2 out of 7 parents indicate the care provided has remained the same pre- and post-pandemic. 3 out of 7 patients felt that their care has improved due to the following reason: treatment was completed more quickly; wards looked less busy as there were limited patients present at one time; there was a reduced length of stay compared to pre-COVID.
• Children’s questionnaires:
- 100% (9 out of 9) children were happy with the care received at daycare.
- 22.2% (2 out of 9) children reported being worried/anxious due to having bloods and cannula taken (1) and missing school (1).
- 5 out of 9 children had play therapist input and they all found it helpful.
Key learning points/Conclusion
Despite the COVID pandemic restrictions, all young people and families had a positive experience during their day care treatments. Effective communication and engaging the patients and families, and providing appropriate explanations to any delays in treatment is vital. The overall experience has provided an opportunity to reflect on the systems to manage the day care treatments, which we presume has been the case in many centres. Allied health professionals like play therapists and youth teams provide immense support to the young people who are attending day care for regular treatments. Provision of these services to all young people if appropriate will enable positive experiences to the patients. Limitation of this survey was a small sample size with the response rate of only 23%. Further survey over an extended period may provide more insight in this area.

Abstract
Introduction/Background Juvenile dermatomyositis is a rare inflammatory disease with a reported incidence of 0.8–4.1 per million children per year. It presents with a constellation of symptoms and signs of inflammation of skin and muscle, and is associated with significant morbidity if untreated. Juvenile systemic sclerosis (JSSc) is an even rarer rheumatological condition of childhood with significant risk of internal organ involvement, especially cardiopulmonary disease. We herewith present the case of a 7-year-old boy with history of hypothyroidism associated with a PAX8 gene variant who presented with clinical features of an overlap of Systemic Sclerosis with JDM with supportive autoantibody profile. Description/Method A 7-year-old boy presented with a history of restricted range of movements in his hands – noted due to difficulties with pen grip – and calcinosis. He reported symptoms of fatigue, intolerance to cold with colour changes to hands and feet, stiffness of movements particularly in the morning, and infrequent episodes of choking. His past medical history was significant for hypothyroidism secondary to a paternally inherited PAX8 missense mutation, and there is a family history of Raynaud’s and hypothyroidism. A detailed examination identified diffusely swollen hands with sclerodactyly, calcinosis of his elbows and fingertips, and limited flexion of his fingers and wrists. He also had telangiectasia of his upper eyelids, Gottron’s papules over his knees and elbows, and sluggish circulation in his hands and feet. He had evidence of mild proximal muscle weakness. His investigations revealed mild elevation of muscle enzymes with normal inflammatory markers. His autoantibody profile showed a moderately positive ANA titre of 1600 with a nucleolar pattern, and was positive for anti-NXP2 and anti-SCL-100 antibodies MRI scan of the pelvis showed no evidence of myositis, echocardiogram was normal and a high-resolution CT scan of chest was normal with no features of interstitial lung disease. The overall picture was one of Systemic Sclerosis/JDM overlap with CREST syndrome. He was commenced on induction therapy with IV Methylprednisolone and Cyclophosphamide in view of the calcinosis. After three cycles of Cyclophosphamide and weaning course of oral corticosteroids, his energy levels are significantly improved and he has better overall mobility with no significant proximal muscle weakness (Childhood Myositis Assessment Scale score 49/53). However, flexion of his fingers remains limited albeit better; he has ongoing fingertip calcinosis but fewer lesions over his elbows. He has been commenced on weekly subcutaneous Methotrexate as he completes Cyclophosphamide. Discussion/Results This patient had an unusual medical history of early onset thyroid dysfunction, the genetic testing for which revealed a missense PAX8 gene variant [c.49G>Ap.(Gly17Arg)] (also present in his father, who is euthyroid). This was classified as being of uncertain significance, although felt to clinically be the most likely cause for his hypothyroidism. There was no evidence to suggest that PAX8 gene mutations increased the risk of autoimmune conditions. There is evidence that PAX8 gene mutations, when expressed on malignant cells, may confer resistance to chemotherapy, which made us rethink the plan to commence him on Cyclophosphamide. However, we were reassured that in constitutional variants, there is no increased risk of cancer, and no known history of resistance to Cyclophosphamide. This patient also demonstrated an interesting antibody pattern, as he was positive for anti-NXP2 antibodies (indicating high risk for calcinosis) and anti-SCL-100 antibodies, which are associated with a clinical subset of patients with overlap of Systemic Sclerosis and JDM and associated with extensive extra-muscular features. He had two distinct clinical phenotypes of calcinosis, which is probably explained by the presence of two autoantibodies that increase the risk of calcinosis. Key learning points/Conclusion Although JDM has bimodal age group for presentation in childhood, only 3% of systemic sclerosis are seen in childhood, which makes this an extremely unusual presentation, given the age, gender and the overlap features (clinical and immunological). We explored whether this rare presentation could be linked to the underlying PAX8 gene mutations, but we could not find any association. With the clinical diagnosis of systemic sclerosis, it was important to rule out cardiopulmonary complications. The other consideration was regarding the choice of therapeutic agent - whether the germline PAX8 gene variants could increase the risk of malignancies or cause resistance to chemotherapeutic agents like Cyclophosphamide, for neither of which we could find any evidence. Extensive calcinosis cutis in this patient could be explained by the presence of two risk factors (CREST syndrome and JDM with NXP2 antibodies).

Abstract
Background Research priority setting is a useful approach to decide which unanswered questions are most worth trying to solve through research. The aim is to reduce bias in the research agenda. Traditionally, research was decided by funders, policymakers, and academics with limited influence from other stakeholders like people living with health conditions, caregivers, or the community. This can lead to research gaps that fail to address these important stakeholder needs. The objective of this study is to identify the top research priorities for Rheumatic and Musculoskeletal Disease (RMD) research in Ireland.
Methods The process framework included a design workshop, two online surveys and a review of the literature. Participants 545 people completed the first survey to identify RMD research topics relevant to Ireland, of which 72% identified as a person living with RMD. 460 people completed the second survey to prioritise these research topics. Results The first survey had 2185 research topics submitted. These were analysed and grouped into 38 topic areas which were ranked in the second survey. The top three research priorities for RMD research in Ireland focused on preventing RMD progression, RMD diagnosis and its impact, and pain management.
Conclusions The prioritised research topics indicate important areas of RMD research for Ireland. Research funded in response to these co-created research priorities will have increased relevance and impact.

Abstract
Fluorescent biosensors are powerful tools allowing the concentration of metabolites and small molecules, and other properties such as pH and molecular crowding to be measured inside live single cells. The technology has been hampered by lack of simple software to identify cells and quantify biosensor signals in single cells. We have developed a new software package, FRETzel, to address this gap and demonstrate its use by measuring insulin-stimulated glucose uptake in individual fat cells of varying sizes for the first time. Our results support the long-standing hypothesis that larger fat cells are less sensitive to insulin than smaller ones, a finding that has important implications for the battle against type 2 diabetes. FRETzel has been optimized using the messy and crowded environment of cultured adipocytes, demonstrating its utility for quantification of FRET biosensors in a wide range of other cell types, including fibroblasts and yeast via a simple user-friendly quantitative interface. FRETzel is a new software package for easy analysis of FRET signals in cells FRETzel is used to quantify glucose uptake in adipocytes of different sizes Reduced glucose uptake suggests that larger adipocytes have lower insulin sensitivity FRETzel is demonstrated on a range of cell types: yeast, fibroblasts, and adipocytes

Abstract
PURPOSE Idea density has been shown to influence comprehension time for text in various populations. This study aims to explore the influence of spoken idea density on attainment in young, healthy subjects using demographic characteristics. METHODS Students watched two online lectures and answered 10 multiple choice questions on them. Students received one more idea dense (MID) and one less idea dense (LID) lecture on two different subjects. RESULTS Seventy-five students completed the study achieving a higher median score after a less idea-dense lecture (LID = 7(3), MID = 6(3), p = 0.04). Artificial neural network models revealed the first language as the main predictor of exam performance. The odds ratio (OR) of obtaining ≥70% after a more idea-dense lecture was six-time higher for the first language versus second language English speakers (OR = 5.963, 95% CI 1.080-32.911, p = 0.041). The odds ratio was not significant when receiving a less dense lecture (OR = 2.298, 95% CI 0.635-8.315, p = 0.205). Second-language speakers benefited from receiving a lower idea density, achieving a 10.8% score increase from high to low density, versus a 3.2% increase obtained by first language speakers. CONCLUSIONS The propositional idea density of lectures directly influences students' comprehension, and disproportionately for second language speakers; revealing the possibility of reduced spoken idea density in levelling the attainment differential between first and second language speakers.

Abstract
AIM To report prospective longitudinal data of early vocaliszations of infants identified "at-risk" of cerebral palsy (CP) for early identification of communication impairment. METHOD This case-control longitudinal prospective cohort study reports on the assessment of 36 infants, 18 identified as at-risk of CP at the time of enrolment and 18 typically developing (TD) children, at three time points: 6 months, 9 months and 12 months of age, Data were obtained through criterion and norm referenced assessments of vocaliszation behaviors. RESULTS Early vocal behaviors of infants identified as at-risk of CP did not differ from their age matched peers at 6 months of age, however, significant group differences emerged at 9 and 12 months when pre-canonical and canonical babble typically emerge. Generalized linear mixed models analysis showed that the rate of development of early language ability and more complex speech-related vocal behaviors was slower for infants at risk of CP when compared to TD infants, with over 75% of infants with CP showing below normal vocal production and impaired language by 12 months of age. INTERPRETATION Our data suggest characteristics of infant vocalizations associated with pre-canonical and canonical babbling provide a strong evidence base for predicting communication outcomes in infants at risk of CP.

Abstract
INTRODUCTION Appendicitis remains the most common intra-abdominal surgical emergency, yet many patients receive postoperative antibiotics and intra-abdominal drains against recommended guidelines. This study assesses the impact of an educational poster on the appropriate use of postoperative antibiotics and intra-abdominal drains in appendicectomy patients. METHODS Patients who underwent an appendicectomy between January and April 2019 ('Poster absent' group) as well as between November 2019 and February 2020 ('Poster present' group) were identified. Data were collected on patient demographics, the presence of complicating features (ie appendiceal abscesses, intraperitoneal pus, gangrene and/or perforation) as well as the use of postoperative antibiotics and intra-abdominal drains in accordance with World Society of Emergency Surgery guidelines. RESULTS One hundred and thirty patients were included in the 'Poster absent' (73 patients) and 'Poster present' (57 patients) groups. After introducing the educational poster there was a significant reduction in the use of postoperative antibiotics (60.5% to 13.8%; p<0.0001) and an insignificant reduction in intra-abdominal drain use (15.2% to 13.2% p>0.05) that were contraindicated in simple appendicitis. There was a significant improvement in the use of postoperative antibiotics (71.9% to 100%; p=0.0019) and an insignificant increase in intra-abdominal drain use (58.8% to 64.3%; p>0.05) that were indicated in complicated appendicitis. The rates of wound infection (4.10% to 0%; p=0.2556) and ileus/obstruction (5.48% to 1.75%; p=0.3846) also reduced. CONCLUSION This small study demonstrated that a simple and appropriately targeted intervention of an educational poster can significantly improve and reduce variation in the management of appendicectomy patients and may reduce postoperative complications.

Abstract
Introduction: Saliva represents a less invasive alternative to nasopharyngeal swab (NPS) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection. SalivaDirect is a nucleic acid extraction-free method for detecting SARS-CoV2 in saliva specimens. Studies evaluating the concordance of gold standard NPS and newly developed SalivaDirect protocols are limited. The aim of our study was to assess SalivaDirect as an alternative method for COVID-19 testing. Methods: Matching NPS and saliva samples were analysed from a cohort of symptomatic (n=127) and asymptomatic (n=181) participants recruited from hospital and university settings, respectively. RNA was extracted from NPS while saliva samples were subjected to the SalivaDirect protocol before RT-qPCR analysis. The presence of SARS-Cov-2 was assessed using RdRp and N1 gene targets in NPS and saliva, respectively. Results: Overall we observed 94.3% sensitivity (95% CI 87.2-97.5%), and 95.9% specificity (95% CI 92.4-97.8%) in saliva when compared to matching NPS samples. Analysis of concordance demonstrated 95.5% accuracy overall for the saliva test relative to NPS, and a very high level of agreement (κ coefficient = 0.889, 95% CI 0.833-0.946) between the two sets of specimens. Fourteen of 308 samples were discordant, all from symptomatic patients. Ct values were >30 in 13/14 and >35 in 6/14 samples. No significant difference was found in the Ct values of matching NPS and saliva sample ( p=0.860). A highly significant correlation (r = 0.475, p<0.0001) was also found between the Ct values of the concordant positive saliva and NPS specimens. Conclusions: Use of saliva processed according to the SalivaDirect protocol represents a valid method to detect SARS-CoV-2. Accurate and less invasive saliva screening is an attractive alternative to current testing methods based on NPS and would afford greater capacity to test asymptomatic populations especially in the context of frequent testing.

Abstract
PURPOSE Given that children with Down syndrome (DS) have language learning difficulties, concerns have been raised about the capacity of these children to acquire two (or more) languages. This research examines the language profiles of bilingual children with DS and typically developing (TD) children in comparison to monolinguals, with a view towards identifying the factors associated with language abilities within these populations. METHOD Four groups of children were recruited: Welsh-English bilinguals with DS (n=10), English monolinguals with DS (n=10), TD Welsh-English bilinguals (n=10) and TD English monolinguals (n=10). Children were individually matched on nonverbal cognitive ability (NVCA) to each child in the bilingual DS group and the four groups were matched on socioeconomic status and gender. Bilinguals were matched on current and lifetime exposure to Welsh and age of first exposure to their L2. Within DS and TD groups, chronological age was statistically controlled for. Language abilities were assessed via standardised assessments and specially designed tasks. Bilinguals were assessed in both of their languages. RESULTS Results show no effect of language status on measures of expressive and receptive language abilities or phonological awareness. Language impairments were evident for both DS groups, particularly for expressive morphosyntax. Welsh receptive vocabulary scores of the bilinguals with DS were comparable to the TD bilinguals. Working memory, phonological awareness and chronological age were the strongest predictors of receptive language outcomes in both DS groups, explaining 90% of the variability. CONCLUSIONS In conclusion, we report no adverse outcomes on language development for bilinguals with DS. To our knowledge, this is the first group study of bilingualism in children with DS within the UK. Findings align with and add to the growing body of literature that reports that bilingualism does not negatively impact the language development of children with developmental disabilities. Clinical and educational implications are discussed.

Abstract
It is a clinically well-established fact that patients with diabetes have very poor stroke outcomes. Yet, the underlying mechanisms remain largely unknown. Our previous studies showed that male diabetic animals show greater hemorrhagic transformation (HT), profound loss of cerebral vasculature in the recovery period, and poor sensorimotor and cognitive outcomes after ischemic stroke. This study aimed to determine the impact of iron chelation with deferoxamine (DFX) on (1) cerebral vascularization patterns and (2) functional outcomes after stroke in control and diabetic rats. After 8 weeks of type 2 diabetes induced by a combination of high-fat diet and low-dose streptozotocin, male control and diabetic animals were subjected to thromboembolic middle cerebral artery occlusion (MCAO) and randomized to vehicle, DFX, or tPA/DFX and followed for 14 days with behavioral tests. Vascular indices (vascular volume and surface area), neurovascular remodeling (AQP4 polarity), and microglia activation were measured. Brain microvascular endothelial cells (BMVEC) from control and diabetic animals were evaluated for the impact of DFX on ferroptotic cell death. DFX treatment prevented vasoregression and microglia activation while improving AQP4 polarity as well as blood-brain barrier permeability by day 14 in diabetic rats. These pathological changes were associated with improvement of functional outcomes. In control rats, DFX did not have an effect. Iron increased markers of ferroptosis and lipid reactive oxygen species (ROS) to a greater extent in BMVECs from diabetic animals, and this was prevented by DFX. These results strongly suggest that (1) HT impacts post-stroke vascularization patterns and recovery responses in diabetes, (2) treatment of bleeding with iron chelation has differential effects on outcomes in comorbid disease conditions, and (3) iron chelation and possibly inhibition of ferroptosis may provide a novel disease-modifying therapeutic strategy in the prevention of post-stroke cognitive impairment in diabetes.
