We present the first results from a new backend on the Australian Square Kilometre Array Pathfinder, the Commensal Realtime ASKAP Fast Transient COherent (CRACO) upgrade. CRACO records millisecond time resolution visibility data, and searches for dispersed fast transient signals including fast radio bursts (FRB), pulsars, and ultra-long period objects (ULPO). With the visibility data, CRACO can localise the transient events to arcsecond-level precision after the detection. Here, we describe the CRACO system and report the result from a sky survey carried out by CRACO at 110-ms resolution during its commissioning phase. During the survey, CRACO detected two FRBs (including one discovered solely with CRACO, FRB 20231027A), reported more precise localisations for four pulsars, discovered two new RRATs, and detected one known ULPO, GPM J1839 $-$10, through its sub-pulse structure. We present a sensitivity calibration of CRACO, finding that it achieves the expected sensitivity of 11.6 Jy ms to bursts of 110 ms duration or less. CRACO is currently running at a 13.8 ms time resolution and aims at a 1.7 ms time resolution before the end of 2024. The planned CRACO has an expected sensitivity of 1.5 Jy ms to bursts of 1.7 ms duration or less and can detect $10\times$ more FRBs than the current CRAFT incoherent sum system (i.e. 0.5 $-$2 localised FRBs per day), enabling us to better constrain the models for FRBs and use them as cosmological probes.
Residual blood specimens collected at health facilities may be a source of samples for serosurveys of adults, a population often neglected in community-based serosurveys. Anonymized residual blood specimens were collected from individuals 15 – 49 years of age attending two sub-district hospitals in Palghar District, Maharashtra, from November 2018 to March 2019. Specimens also were collected from women 15 – 49 years of age enrolled in a cross-sectional, community-based serosurvey representative at the district level that was conducted 2 – 7 months after the residual specimen collection. Specimens were tested for IgG antibodies to measles and rubella viruses. Measles and rubella seroprevalence estimates using facility-based specimens were 99% and 92%, respectively, with men having significantly lower rubella seropositivity than women. Age-specific measles and rubella seroprevalence estimates were similar between the two specimen sources. Although measles seropositivity was slightly higher among adults attending the facilities, both facility and community measles seroprevalence estimates were 95% or higher. The similarity in measles and rubella seroprevalence estimates between the community-based and facility serosurveys highlights the potential value of residual specimens to approximate community seroprevalence.
The flow near a moving contact line depends on the dynamic contact angle, viscosity ratio and capillary number. We report experiments involving immersing a plate into a liquid bath, concurrently measuring the interface shape, interfacial velocity and fluid flow using digital image processing and particle image velocimetry. All experiments were performed at low plate speeds to maintain small Reynolds and capillary numbers for comparison with viscous theories. The dynamic contact angle, measured in the viscous phase, was kept below $90^{\circ }$ and the viscosity ratio, $\lambda < 1$. This region of parameter space is largely unexplored for advancing contact lines. An important aim of the present study is to provide new experimental data against which new contact line models can be developed. The flow field is directly compared against the prediction from the viscous theory of Huh & Scriven (J. Colloid Interface Sci., vol. 35, issue 1, 1971, pp. 85–101) but with a slight modification involving the curved interface. Remarkable agreement is found between experiments and theory across a wide parameter range. The prediction for interfacial speed from Huh & Scriven is also in excellent agreement with experiments except in the vicinity of the contact line. Material points along the interface were found to rapidly slow down near the contact line, thus alleviating the singularity at the moving contact line. To the best of our knowledge, such a detailed test of theoretical models has not been performed before and we hope the present study will spur new modelling efforts in the field.
Residual blood specimens provide a sample repository that could be analyzed to estimate and track changes in seroprevalence with fewer resources than household-based surveys. We conducted parallel facility and community-based cross-sectional serological surveys in two districts in India, Kanpur Nagar District, Uttar Pradesh, and Palghar District, Maharashtra, before and after a measles-rubella supplemental immunization activity (MR-SIA) from 2018 to 2019. Anonymized residual specimens from children 9 months to younger than 15 years of age were collected from public and private diagnostic laboratories and public hospitals and tested for IgG antibodies to measles and rubella viruses. Significant increases in seroprevalence were observed following the MR SIA using the facility-based specimens. Younger children whose specimens were tested at a public facility in Kanpur Nagar District had significantly lower rubella seroprevalence prior to the SIA compared to those attending a private hospital, but this difference was not observed following the SIA. Similar increases in rubella seroprevalence were observed in facility-based and community-based serosurveys following the MR SIA, but trends in measles seroprevalence were inconsistent between the two specimen sources. Despite challenges with representativeness and limited metadata, residual specimens can be useful in estimating seroprevalence and assessing trends through facility-based sentinel surveillance.
New advancements in radio data post-processing are underway within the Square Kilometre Array (SKA) precursor community, aiming to facilitate the extraction of scientific results from survey images through a semi-automated approach. Several of these developments leverage deep learning methodologies for diverse tasks, including source detection, object or morphology classification, and anomaly detection. Despite substantial progress, the full potential of these methods often remains untapped due to challenges associated with training large supervised models, particularly in the presence of small and class-unbalanced labelled datasets.
Self-supervised learning has recently established itself as a powerful methodology to deal with some of the aforementioned challenges, by directly learning a lower-dimensional representation from large samples of unlabelled data. The resulting model and data representation can then be used for data inspection and various downstream tasks if a small subset of labelled data is available.
In this work, we explored contrastive learning methods to learn suitable radio data representations by training the SimCLR model on large collections of unlabelled radio images taken from the ASKAP EMU and SARAO MeerKAT GPS surveys. The resulting models were fine-tuned over smaller labelled datasets, including annotated images from various radio surveys, and evaluated on radio source detection and classification tasks. Additionally, we employed the trained self-supervised models to extract features from radio images, which were used in an unsupervised search for objects with peculiar morphology in the ASKAP EMU pilot survey data. For all considered downstream tasks, we reported the model performance metrics and discussed the benefits brought by self-supervised pre-training, paving the way for building radio foundational models in the SKA era.
The Northern Territory (NT) has Australia’s highest mental health burden. It has a diverse and transient population, including Aboriginal and Torres Strait Islander people and various multicultural communities. While peer support has been widely used nationwide, in the NT, peer support is poorly implemented in psychosocial support activities.
Objectives
The NT Lived Experience Network (NTLEN), in allyship with a team of researchers from Flinders University, has secured multiple fundings aimed to develop, implement, and evaluate a peer education and recovery program called Recovery Together (RT) for individuals with mental health and alcohol and drug use issues and related challenges.
Methods
The suitable evaluation approach was co-designed with live experience representatives from NTLEN and other local key stakeholders. It applied a mixed-method approach, including pre and post-program surveys (n=64) and individual interviews with program participants and the program delivery team (n=32). The evaluation findings were also informed by data collected by NTLEN via feedback forms n=38). We also used a co-design approach to develop survey instruments to ensure they were strengths-based and recovery-oriented.
Results
Participants reported poor and fair self-perceived health, high stress levels, dissatisfaction with their relationships and relatively low recovery scores, which showed improvements at post-program completion. They discussed their journeys in the interviews and shared their experiences with local mental health services and the Recovery Together program. Many expressed that mental health professionals are not necessarily the care providers they feel comfortable engaging with. However, they described their experience with the peer program as highly positive, empowering, safe, non-judgmental, and beneficial, satisfying their support needs. The program gave them hope and tools to manage their mental health challenges and opportunities to gain insight into non-clinical aspects of recovery. Participants conceptualised personal recovery in their own words and described the facilitators and barriers to their recovery. They emphasised that recovery is being empowered, strong within themselves and the leader of their journey, living their best possible life, understanding themselves, having the necessary knowledge about mental health, and looking forward in a hopeful way.
Conclusions
Our findings highlighted the demand and need for ongoing delivery of the RT program in the NT, which was highly effective in supporting personal recovery, addressing the service delivery gap and complementing the available clinical and mental health practices. They also showed the importance of providing recovery-oriented and trauma-informed education for medical and mental health professionals.
Families and friends of individuals with alcohol and other drug use (AOD) issues are highly stigmatised and vulnerable, which often leads to social isolation, decreased quality of life, psychosocial vulnerability, heightened distress, less access to social support, and development of maladaptive coping strategies and own mental health challenges and/or AOD use issues. While peer support for families is commonplace in Australia, in Darwin, psychosocial support activities delivered by peers are very sparse.
Objectives
The NT Lived Experience Network (NTLEN), in allyship with a team of researchers from Flinders University, has secured multiple fundings aimed to develop, implement, and evaluate a peer education and recovery program called Circles of Support (CoS) for families and friends of persons with AOD use issues.
Methods
The suitable evaluation approach was co-designed with live experience representatives from NTLEN and other local key stakeholders. It applied a mixed-method approach, including pre and post-program surveys (n=26) and individual interviews with program participants and the program delivery team (n=11). We also used a co-design approach to develop survey instruments to ensure they were strengths-based and recovery-oriented.
Results
While most participants showed sound stress management skills and understanding of stressors at the program start, about 30% did not think they could handle distress if it got worse and did not have the tools to live the life they wanted. Also, about 25% did not know when to ask for help. Many participants (40%) expressed that they were not hopeful about possible changes in their own family context, such as fewer experiences of stress. By the end of the program, participants reported lower stress levels and higher total empowerment scores. The qualitative interviews highlighted the complexities and challenges participant faced in their journeys. Among them, stigma was considered the most critical, especially among participants from culturally and linguistically diverse backgrounds. In some cases, perceived stigma prevented participants from joining the program. The program was well-received and successful in empowering families and friends and improving their own mental wellbeing. Their key learning and experiences included identifying the stage of their situation, learning to cope with challenges, reducing stress, developing hope, experiencing growth, creating a better and more supportive relationship with their loved ones, and implementing self-care on a regular basis.
Conclusions
Our findings emphasise the critical role of peer support for families and friends in improving their mental health and wellbeing. They also draw attention to improving help-seeking behaviours, which may be influenced by stigma, shame and prioritising the person’s needs.
Soybean is a major source of vegetable oil and protein worldwide. Globally, India is among the top five producers where soybean is a major oilseed grown under diverse agro-climatic conditions by small and marginal farmers. The present study aims to identify soybean varieties with higher yield levels, resistance to pestdiseases and adaptability to climatic fluctuations. One hundred and twenty-five (125) indigenous and exotic soybean germplasm accessions and five checks were evaluated and characterized for eight agro-morphological traits at five testing locations and also screened for frog-eye leaf spot (FLS) and yellow mosaic virus (YMV) diseases under hot-spot locations during the rainy season. A wide range of variability was observed among accessions for days to 50% flowering (39–59), plant height (41–111 cm), number of nodes/plant (10–30), pod clusters/plant (14–39), number of pods/plant (40–102), days to maturity (96–115), grain yield/plant (4.89–16.54 g) and 100-seed weight (6.02–13.72 g). Among various traits, 100-seed weight (0.45), number of pods/plant (0.60) and number of pod clusters/plant (0.38) were found to be major yield-contributing traits as they exhibited highly significant correlation with grain yield/plant. Principal components PCI and PCII with eigen value >1 accounted for 42.66 and 27.08% of the total variation, respectively. Accessions G24 (EC 393222) from Taiwan and G40 (IMP-1) from the USA belonging to cluster IV were found promising for multiple yield traits and JS 20–38 from cluster III for earliness as per cluster analysis. GGE biplot average environment coordination (AEC) view revealed that the accessions viz., G11 (EC 333872), G2 (EC 251506) and G47 (TNAU-S-55) were the best performing stable genotypes in terms of grain yield/plant across locations. Twelve accessions had a high level of resistance against both FLS and YMV diseases under natural hot-spot conditions which can be utilized as promising donors in the soybean breeding programme.
Adequate nutrition is necessary during childhood and early adolescence for adequate growth and development. Hence, the objective of the study was to assess the association between dietary intake and blood levels of minerals (calcium, iron, zinc, and selenium) and vitamins (folate, vitamin B12, vitamin A, and vitamin D) in urban school going children aged 6–16 years in India, in a multicentric cross-sectional study. Participants were enrolled from randomly selected schools in ten cities. Three-day food intake data was collected using a 24-h dietary recall method. The intake was dichotomised into adequate and inadequate. Blood samples were collected to assess levels of micronutrients. From April 2019 to February 2020, 2428 participants (50⋅2 % females) were recruited from 60 schools. Inadequate intake for calcium was in 93⋅4 % (246⋅5 ± 149⋅4 mg), iron 86⋅5 % (7⋅6 ± 3⋅0 mg), zinc 84⋅0 % (3⋅9 ± 2⋅4 mg), selenium 30⋅2 % (11⋅3 ± 9⋅7 mcg), folate 73⋅8 % (93⋅6 ± 55⋅4 mcg), vitamin B12 94⋅4 % (0⋅2 ± 0⋅4 mcg), vitamin A 96⋅0 % (101⋅7 ± 94⋅1 mcg), and vitamin D 100⋅0 % (0⋅4 ± 0⋅6 mcg). Controlling for sex and socioeconomic status, the odds of biochemical deficiency with inadequate intake for iron [AOR = 1⋅37 (95 % CI 1⋅07–1⋅76)], zinc [AOR = 5⋅14 (95 % CI 2⋅24–11⋅78)], selenium [AOR = 3⋅63 (95 % CI 2⋅70–4⋅89)], folate [AOR = 1⋅59 (95 % CI 1⋅25–2⋅03)], and vitamin B12 [AOR = 1⋅62 (95 %CI 1⋅07–2⋅45)]. Since there is a significant association between the inadequate intake and biochemical deficiencies of iron, zinc, selenium, folate, and vitamin B12, regular surveillance for adequacy of micronutrient intake must be undertaken to identify children at risk of deficiency, for timely intervention.
Women and gender-diverse people with early psychosis are at risk for suboptimal sexual health outcomes, yet little research has explored their sexual health experiences.
Aims
This study explored sexual health experiences and related priorities among women and gender-diverse people with early psychosis, to identify opportunities for improvements in sexual health and well-being.
Method
Semi-structured individual qualitative interviews explored how patient participants (n = 19, aged 18–31 years, cisgender and transgender women and non-binary individuals) receiving clinical care from early psychosis programmes in Ontario, Canada, experienced their sexual health, including sexual function and behaviour. Thematic analysis was conducted, with triangulation from interviews/focus groups with clinicians (n = 36) who provide sexual and mental healthcare for this population.
Results
Three key themes were identified based on patient interviews: theme 1 was the impact of psychotic illness and its treatments on sexual function and activity, including variable changes in sex drive, attitudes and behaviours during acute psychosis, vulnerability to trauma and medications; theme 2 related to intimacy and sexual relationships in the context of psychosis, with bidirectional effects between relationships and mental health; and theme 3 comprised autonomy, identity and intersectional considerations, including gender, sexuality, culture and religion, which interplay with psychosis and sexual health. Clinicians raised each of these priority areas, but emphasised risk prevention relative to patients’ more holistic view of their sexual health and well-being.
Conclusions
Women and non-binary people with early psychosis have wide-ranging sexual health priorities, affecting many facets of their lives. Clinical care should incorporate this knowledge to optimise sexual health and well-being in this population.
The difficulty of diagnosing prostate cancer (PC) with the available biomarkers frequently leads to over-diagnosis and overtreatment of PC, underscoring the need for novel molecular signatures. The purpose of this review is to provide a summary of the currently available cellular metabolomics for PC molecular signatures. A comprehensive search on PubMed was conducted to find studies published between January 2004 and August 2022 that reported biomarkers for PC detection, development, aggressiveness, recurrence and treatment response. Although potential studies have reported the presence of distinguishing molecules that can distinguish between benign and cancerous prostate tissue. However, there are few studies looking into signature molecules linked to disease development, therapy response or tumour recurrence. The majority of these studies use high-dimensional datasets, and the number of potential metabolites investigated frequently exceeds the size of the available samples. In light of this, pre-analytical, statistical, methodological and confounding factors such as antiandrogen therapy (NAT) may also be linked to the identified chemometric multivariate differences between PC and relevant control samples in the datasets. Despite the methodological and procedural challenges, a range of methodological groups and processes have consistently identified a number of signature metabolites and pathways that appear to imply a substantial involvement in the cellular metabolomics of PC for tumour formation and recurrence.
Evolutionary studies on Dengue virus (DENV) in endemic regions are necessary since naturally occurring mutations may lead to genotypic variations or shifts in serotypes, which may lead to future outbreaks. Our study comprehends the evolutionary dynamics of DENV, using phylogenetic, molecular clock, skyline plots, network, selection pressure, and entropy analyses based on partial CprM gene sequences. We have collected 250 samples, 161 in 2017 and 89 in 2018. Details for the 2017 samples were published in our previous article and that of 2018 are presented in this study. Further evolutionary analysis was carried out using 800 sequences, which incorporate the study and global sequences from GenBank: DENV-1 (n = 240), DENV-3 (n = 374), and DENV-4 (n = 186), identified during 1944–2020, 1956–2020, and 1956–2021, respectively. Genotypes V, III, and I were identified as the predominant genotypes of the DENV-1, DENV-3, and DENV-4 serotypes, respectively. The rate of nucleotide substitution was found highest in DENV-3 (7.90 × 10−4 s/s/y), followed by DENV-4 (6.23 × 10−4 s/s/y) and DENV-1 (5.99 × 10−4 s/s/y). The Bayesian skyline plots of the Indian strains revealed dissimilar patterns amongst the population size of the three serotypes. Network analyses showed the presence of different clusters within the prevalent genotypes. The data presented in this study will assist in supplementing the measures for vaccine development against DENV.
To evaluate the rate of coinfections and secondary infections seen in hospitalized patients with COVID-19 and antimicrobial prescribing patterns.
Methods:
This single-center, retrospective study included all patients aged ≥18 years admitted with COVID-19 for at least 24 hours to a 280-bed, academic, tertiary-care hospital between March 1, 2020, and August 31, 2020. Coinfections, secondary infections, and antimicrobials prescribed for these patients were collected.
Results:
In total, 331 patients with a confirmed diagnosis of COVID-19 were evaluated. No additional cases were identified in 281 (84.9%) patients, whereas 50 (15.1%) had at least 1 infection. In total, of 50 patients (15.1%) who were diagnosed with coinfection or secondary infection had bacteremia, pneumonia, and/or urinary tract infections. Patients who had positive cultures, who were admitted to the ICU, who required supplemental oxygen, or who were transferred from another hospital for higher level of care were more likely to have infections. The most commonly used antimicrobials were azithromycin (75.2%) and ceftriaxone (64.9%). Antimicrobials were prescribed appropriately for 55% of patients.
Conclusions:
Coinfection and secondary infections are common in patients who are critically ill with COVID-19 at hospital admission. Clinicians should consider starting antimicrobial therapy in critically ill patients while limiting antimicrobial use in patients who are not critically ill.
We present WALLABY pilot data release 1, the first public release of H i pilot survey data from the Wide-field ASKAP L-band Legacy All-sky Blind Survey (WALLABY) on the Australian Square Kilometre Array Pathfinder. Phase 1 of the WALLABY pilot survey targeted three
$60\,\mathrm{deg}^{2}$
regions on the sky in the direction of the Hydra and Norma galaxy clusters and the NGC 4636 galaxy group, covering the redshift range of
$z \lesssim 0.08$
. The source catalogue, images and spectra of nearly 600 extragalactic H i detections and kinematic models for 109 spatially resolved galaxies are available. As the pilot survey targeted regions containing nearby group and cluster environments, the median redshift of the sample of
$z \approx 0.014$
is relatively low compared to the full WALLABY survey. The median galaxy H i mass is
$2.3 \times 10^{9}\,{\rm M}_{{\odot}}$
. The target noise level of
$1.6\,\mathrm{mJy}$
per 30′′ beam and
$18.5\,\mathrm{kHz}$
channel translates into a
$5 \sigma$
H i mass sensitivity for point sources of about
$5.2 \times 10^{8} \, (D_{\rm L} / \mathrm{100\,Mpc})^{2} \, {\rm M}_{{\odot}}$
across 50 spectral channels (
${\approx} 200\,\mathrm{km \, s}^{-1}$
) and a
$5 \sigma$
H i column density sensitivity of about
$8.6 \times 10^{19} \, (1 + z)^{4}\,\mathrm{cm}^{-2}$
across 5 channels (
${\approx} 20\,\mathrm{km \, s}^{-1}$
) for emission filling the 30′′ beam. As expected for a pilot survey, several technical issues and artefacts are still affecting the data quality. Most notably, there are systematic flux errors of up to several 10% caused by uncertainties about the exact size and shape of each of the primary beams as well as the presence of sidelobes due to the finite deconvolution threshold. In addition, artefacts such as residual continuum emission and bandpass ripples have affected some of the data. The pilot survey has been highly successful in uncovering such technical problems, most of which are expected to be addressed and rectified before the start of the full WALLABY survey.
Three-dimensional computed tomography reconstruction of the face has recently been presented as a newer diagnostic tool in coronavirus disease 2019 associated mucormycosis. This study was conducted to compare three-dimensional computed tomography reconstruction with conventional two-dimensional computed tomography in coronavirus disease 2019 associated mucormycosis.
Methods
A total of 123 mucormycosis patients underwent three-dimensional computed tomography reconstruction after a comprehensive clinical investigation. The involvement of the facial skeleton was noted.
Results
The anterior maxillary wall was most commonly involved (9.8 per cent). Involvement of the lateral maxillary wall was noted in 6.5 per cent of patients. Sixty-seven patients (54.5 per cent) underwent endoscopic surgery, 22 (17.9 per cent) underwent open surgical procedures, and 12 (9.8 per cent) had combined endoscopic and open surgical procedures. In 21 patients (17.1 per cent), open surgery was performed in the first instance based on additional three-dimensional computed tomography findings, and revision surgical procedures were avoided.
Conclusion
Three-dimensional computed tomography of the face was found to be superior in determining the extent of disease. It reduces delays in diagnosis, facilitates surgical planning and minimises the need for multiple surgical procedures.
Aging leads to progressive deterioration of physiological function and predisposes to pathological processes. Common geriatric syndromes (such as depression, dementia, falls, mobility impairment, delirium, and osteoporosis), along with age-related impairment in appetite, absorption, and food intake, affect nutrition, symptom presentation, and response to therapy of common gastrointestinal (GI) disorders in the elderly. Age-associated changes in drug metabolism and polypharmacy can result in potential interactions and side effects of drugs used in the treatment of GI diseases, which in turn complicates their management. Polypharmacy, which is common in the elderly, can also exacerbate digestive symptoms. Elderly patients with neurocognitive decline often have atypical presentation of their GI disorders. These factors can make the diagnosis of GI diseases in the elderly more challenging, as they may require different management approaches. In this chapter, we discuss the common GI disorders that affect the elderly with special focus on age-related pathophysiology and clinical implications.
Mung bean is highly susceptible to insect attack during storage. Hermetic storage is an effective technique to control insect damage. This study investigated the potential of the hermetic SuperGrain bag (SGB) for controlling bruchids during storage. The dry samples were packed in SGB infested with adult bruchids (SGB-I), SGB natural field infested (SGB-N), woven polypropylene bags (WPP-I and WPP-N) and kept at room temperature for 180 days. Oxygen (O2) and carbon dioxide (CO2) concentrations were measured at 15 days intervals. Moisture content, infestation level, seed damage and weight loss were determined at 60 days intervals. Seed colour, hardness, crude protein and fat contents were analysed before and after storage. The O2 level decreased to 10.09%, whereas the CO2 level increased to 8.87% in both SGB-I and SGB-N treatments. The moisture content of mung bean was maintained as onset storage in both SGB-N and SGB-I treatments, whereas reduced in WPP-N (9.26% db) and WPP-I (9.21% db). In SGB treatments, no significant bruchids were detected, but they increased drastically in WPP-N (52 ± 9) and WPP-I (377 ± 14). Seed damage (2–3%) and weight loss (0.8–1.0%) were recorded in both SGB-N and SGB-I. Conversely, seed damage reached 26.67 and 54.17%, corresponding to weight losses of 12.33 and 20.82% in WPP-N and WPP-I, respectively. Seed colour, hardness, crude protein and fat contents in SGBs showed no significant changes than in the WPP bags. The study illustrated that the SGB is an efficient hermetic device in protecting mung beans against bruchids attacks compared to the WPP bags.
