Achieving eco-innovative smart glass design with the integration of opinion mining, QFD and TRIZ.

Modern consumption patterns lead to massive waste, which poses challenges in storage and highlights the urgent need for more sustainable product development. Customer feedback on products plays a crucial role in product design, yet previous studies overlooked these invaluable insights. In response, this study introduces a novel systematic methodology that integrates the strengths of text mining, Quality Function Deployment (QFD), and the Theory of Inventive Problem Solving (TRIZ). Text mining techniques are utilized to extract customer requirements from online platforms, while QFD is used to translate these requirements into technical specifications. By integrating the contradiction matrix from TRIZ theory with the triptych, technical conflicts are resolved. The design process for next-generation smart glasses is employed as an illustrative case to validate the proposed integrated innovation design approach. Analytical outcomes suggest that the introduced methodology can effectively address sustainable product design challenges and sets the stage for future advancements in smart glasses.

Cognitive outcome and its neural correlates after cardiorespiratory arrest in childhood.

Hypoxia-ischaemia (HI) can result in structural brain abnormalities, which in turn can lead to behavioural deficits in various cognitive and motor domains, in both adult and paediatric populations. Cardiorespiratory arrest (CA) is a major cause of hypoxia-ischaemia in adults, but it is relatively rare in infants and children. While the effects of adult CA on brain and cognition have been widely studied, to date, there are no studies examining the neurodevelopmental outcome of children who suffered CA early in life. Here, we studied the long-term outcome of 28 children who suffered early CA (i.e., before age 16). They were compared to a group of control participants (n = 28) matched for age, sex and socio-economic status. The patient group had impairments in the domains of memory, language and academic attainment (measured using standardised tests). Individual scores within the impaired range were most commonly found within the memory domain (79%), followed by academic attainment (50%), and language (36%). The patient group also had reduced whole brain grey matter volume, and reduced volume and fractional anisotropy of the white matter. In addition, lower performance on memory tests was correlated with bilaterally reduced volume of the hippocampi, thalami, and striatum, while lower attainment scores were correlated with bilateral reduction of fractional anisotropy in the superior cerebellar peduncle, the main output tract of the cerebellum. We conclude that patients who suffered early CA are at risk of developing specific cognitive deficits associated with structural brain abnormalities. RESEARCH HIGHLIGHTS: Our data shed light on the long-term outcome and associated neural mechanisms after paediatric hypoxia-ischaemia as a result of cardiorespiratory arrest. Patients had impaired scores on memory, language and academic attainment. Memory impairments were associated with smaller hippocampi, thalami, and striatum. Lower academic attainment correlated with reduced fractional anisotropy of the superior cerebellar peduncle.

The effect of hypoxic ischemic encephalopathy towards multi-organ complications and its early outcome at a Malaysian district hospital.

INTRODUCTION: Hypoxic ischemic encephalopathy (HIE) is a clinically defined syndrome of disturbed neurologic function in the newborn with evidence of perinatal asphyxia. Stages of HIE are categorised into mild, moderate or severe based on the Sarnat classification. Neurological dysfunction constitutes a part of the wide spectrum of hypoxic ischemic insult as affected infants can have co-existing multi-organ dysfunction which further contributes to morbidities and mortality. This study aims to determine the relationship between the severity of HIE with multi-organ complications and early clinical outcomes. MATERIALS AND METHODS: All neonates who were admitted to the NICU at Hospital Sultan Abdul Halim between January 2018 to December 2022, who fulfilled the inclusion criteria were included. Demographic data, clinical course and investigation results were retrospectively obtained from the medical records. RESULTS: From a total of 90 infants (n = 90) who fulfilled our inclusion criteria, 31 (34%) were mild, 31 (34%) were moderate and 28 (31%) were severe HIE. The mean maternal age was 27 years. Common antenatal issues include diabetes mellitus (37.8%) and anaemia (22.2%). The Apgar scores at 1 and 5 minutes, initial resuscitation requiring intubation, chest compression and adrenaline were associated with higher severity of HIE (p < 0.05). Coagulation dysfunction was the most common complication (79.7%), followed by respiratory dysfunction (33.3%), cardiac dysfunction (28.9%), renal dysfunction (16.1%), haematological dysfunction (15.6%) and hepatic dysfunction (12%). Respiratory and haematological dysfunctions were significantly associated with higher mortality (p < 0.05). There was a significant longer hospital stay (p = 0.023), longer duration of ventilation (p < 0.001) and increase in frequency of seizures (p < 0.001) when comparing moderate and severe HIE patients to mild HIE patients. With increasing severity of HIE, there was also statistically significant higher mortality (p < 0.001). CONCLUSIONS: There is a significant relationship between multiorgan dysfunction, the severity of HIE and mortality. Early anticipation of multi-organ injury is crucial for optimal early management which would reduce the mortality and improve the neurological outcome of the patients.

Anatomo-functional changes in neural substrates of cognitive memory in developmental amnesia: Insights from automated and manual MRI examinations.

Despite bilateral hippocampal damage dating to perinatal or early-childhood period, and severely-impaired episodic memory that unfolds in later childhood, patients with developmental amnesia continue to exhibit well-developed semantic memory across the developmental trajectory. Detailed information on the extent and focality of brain damage in these patients is needed to hypothesize about the neural substrate that supports their remarkable capacity for encoding and retrieval of semantic memory. In particular, we need to assess whether the residual hippocampal tissue is involved in this preservation, or whether the surrounding cortical areas reorganise to rescue aspects of these critical cognitive memory processes after early injury. We used voxel-based morphometry (VBM) analysis, automatic (FreeSurfer) and manual segmentation to characterize structural changes in the brain of an exceptionally large cohort of 23 patients with developmental amnesia in comparison with 32 control subjects. Both the VBM and the FreeSurfer analyses revealed severe structural alterations in the hippocampus and thalamus of patients with developmental amnesia. Milder damage was found in the amygdala, caudate and parahippocampal gyrus. Manual segmentation demonstrated differences in the degree of atrophy of the hippocampal subregions in patients. The level of atrophy in CA-DG subregions and subicular complex was more than 40% while the atrophy of the uncus was moderate (-23%). Anatomo-functional correlations were observed between the volumes of residual hippocampal subregions in patients and selective aspects of their cognitive performance viz, intelligence, working memory, and verbal and visuospatial recall. Our findings suggest that in patients with developmental amnesia, cognitive processing is compromised as a function of the extent of atrophy in hippocampal subregions, such that the greater the damage, the more likely it is that surrounding cortical areas will be recruited to rescue the putative functions of the damaged subregions. Our findings document for the first time not only the extent, but also the limits of circuit reorganization occurring in the young brain after early bilateral hippocampal damage.

An investigation of the PM2.5 concentrations and cumulative inhaled dose during subway commutes in Changchun, China.

Air quality in subway systems is crucial as it affects the health of passengers and staff. Although most tests of PM2.5 concentrations in subway stations have taken place in public areas, PM2.5 is less understood in workplaces. Few studies have estimated the cumulative inhaled dose of passengers based on real-time changes in PM2.5 concentrations as they commute. To clarify the above issues, this study first measured PM2.5 concentrations in four subway stations in Changchun, China, where measuring points included five workrooms. Then, passengers' exposure to PM2.5 during the whole subway commute (20-30 min) was measured and segmented inhalation was calculated. The results showed that PM2.5 concentration in public places ranged from 50 to 180 µg/m3, and was strongly correlated with outdoors. While the PM2.5 average concentration in workplaces was 60 µg/m3, and it was less affected by outdoor PM2.5 concentration. Passenger's cumulative inhalations in single commuting were about 42 µg and 100 µg when the outdoor PM2.5 concentrations were 20-30 µg/m3 and 120-180 µg/m3, respectively. The PM2.5 inhalation in carriages accounted for the largest proportion of the entire commuting, about 25-40%, because of the longer exposure time and higher PM2.5 concentrations. It is recommended to improve the tightness of the carriage and filter the fresh air to improve the air quality inside. The average daily PM2.5 inhaled by staff was 513.53 µg, which was 5-12 times higher than that of passengers. Installing air purification devices in workplaces and reminding staff to take personal protection can positively protect their health.

Pembrolizumab monotherapy versus chemotherapy in platinum-pretreated, recurrent or metastatic nasopharyngeal cancer (KEYNOTE-122): an open-label, randomized, phase III trial.

BACKGROUND: Pembrolizumab previously demonstrated robust antitumor activity and manageable safety in a phase Ib study of patients with heavily pretreated, programmed death ligand 1 (PD-L1)-positive, recurrent or metastatic nasopharyngeal carcinoma (NPC). The phase III KEYNOTE-122 study was conducted to further evaluate pembrolizumab versus chemotherapy in patients with platinum-pretreated, recurrent and/or metastatic NPC. Final analysis results are presented. PATIENTS AND METHODS: KEYNOTE-122 was an open-label, randomized study conducted at 29 sites, globally. Participants with platinum-pretreated recurrent and/or metastatic NPC were randomly assigned (1 : 1) to pembrolizumab or chemotherapy with capecitabine, gemcitabine, or docetaxel. Randomization was stratified by liver metastasis (present versus absent). The primary endpoint was overall survival (OS), analyzed in the intention-to-treat population using the stratified log-rank test (superiority threshold, one-sided P = 0.0187). Safety was assessed in the as-treated population. RESULTS: Between 5 May 2016 and 28 May 2018, 233 participants were randomly assigned to treatment (pembrolizumab, n = 117; chemotherapy, n = 116); Most participants (86.7%) received study treatment in the second-line or later setting. Median time from randomization to data cut-off (30 November 2020) was 45.1 months (interquartile range, 39.0-48.8 months). Median OS was 17.2 months [95% confidence interval (CI) 11.7-22.9 months] with pembrolizumab and 15.3 months (95% CI 10.9-18.1 months) with chemotherapy [hazard ratio, 0.90 (95% CI 0.67-1.19; P = 0.2262)]. Grade 3-5 treatment-related adverse events occurred in 12 of 116 participants (10.3%) with pembrolizumab and 49 of 112 participants (43.8%) with chemotherapy. Three treatment-related deaths occurred: 1 participant (0.9%) with pembrolizumab (pneumonitis) and 2 (1.8%) with chemotherapy (pneumonia, intracranial hemorrhage). CONCLUSION: Pembrolizumab did not significantly improve OS compared with chemotherapy in participants with platinum-pretreated recurrent and/or metastatic NPC but did have manageable safety and a lower incidence of treatment-related adverse events.

A rare case of gouty arthropathy in the spine complicated with acute cord compression.

Gout is one of the most common inflammatory arthropathies in the developed world. However, involvement of the spine is relatively rare, and other sinister differential diagnoses will need to be considered. We describe an unusual case of gouty tophi deposition within the spine in an elderly patient presenting with signs and symptoms of acute cord compression. Important differential diagnoses that need to be excluded include bony metastases from underlying malignancy and other infective/inflammatory causes. Early recognition of imaging findings can avoid delayed or inappropriate medical treatment.

The Silk Vista Baby - The UK experience.

BACKGROUND: The Silk Vista Baby (SVB) flow diverter (FDS) is the only FDS deliverable via a 0.017 inch microcatheter and is specifically designed for the distal vasculature. We sought to evaluate the safety and efficacy of the SVB. MATERIALS AND METHODS: We performed a retrospective review to identify SVB cases at 4 tertiary neurosurgical centres within the U.K. Clinical, procedural, angiographic and follow-up data were collected. RESULTS: We identified 60 patients (35 female, 58%) of average age 54 ± 10.5 (range 30-72) with 61 aneurysms, 50 (81.9%) located in the anterior circulation. The majority of the aneurysms treated were unruptured (46, 75.4%) and saccular (46, 75.4%). Dome size was 6.2 ± 6.2 mm (range 1-36mm) and parent vessel diameter was 2.3 ± 0.4 mm (range 1.2-3.3 mm).An average number of 1.07 devices were implanted. Coils or other devices were implanted in 14 aneurysms (23.3%). At last angiographic follow-up (n = 55), 7.5 ± 4.2 months post-procedure, 32 aneurysms (57.1%) were graded as RRC I, 7 (12.5%) RRC II, and 17 RRC III (30.4%).Clinical complications, excluding death, were seen in 4 patients (6.8%) including 1 delayed aneurysm rupture and 3 symptomatic ischaemic events. Only one patient had permanent morbidity (mRS 1). 3 patients died during follow-up (5.1%); 2 deaths were related to the aneurysms (3.4%) - one ruptured dissecting MCA aneurysm, and one giant partially thrombosed posterior circulation aneurysm. 93% of patients were mRS ≤ 2 at last follow-up. CONCLUSION: The SVB has high rates of technical success and an acceptable safety profile. Distal aneurysms may occlude slower due to relative oversizing of the devices.

Intra-aortic Balloon Pump Use With Extra Corporeal Membrane Oxygenation-A Mock Circulation Loop Study.

Venoarterial extracorporeal membrane oxygenation (ECMO) is used in cardiogenic shock refractory to inotropic support and intra-aortic balloon pump (IABP) support. Peripheral ECMO can lead to ventricular distention, and IABP can be used to mitigate these effects. The aim of this study was to quantify the effects of IABP concomitant with ECMO, under different simulated hemodynamic conditions in a mock circulatory loop. Different simulated states of isolated left ventricular (LV) failure and biventricular failure with graded LV failure severities were supported with ECMO and ECMO with IABP. The impact on left ventricular end-diastolic pressure (LVEDP), volume (LVEDV), coronary flow rate, and cerebral flow rate were evaluated. Left ventricular volumes and pressures increased from the heart failure states with the addition of ECMO. The IABP provided between 3% and 7% reductions in LVEDP and between 1% and 10% reductions in LVEDV. The addition of IABP had minimal effect on cerebral blood flow (0% to 7%), but the variable impact on coronary blood flow with increased diastolic coronary flow of 23% to 50%, but the reduction in mean coronary flow by up to 30%. The efficacy of the IABP was strongly related to ventricular contractility. This study demonstrates the need for careful IABP selection concomitant with ECMO.

Clinical characteristics and outcomes of influenza-associated pulmonary aspergillosis among critically ill patients: a systematic review and meta-analysis.

BACKGROUND: Invasive pulmonary aspergillosis is increasingly identified as a complication of influenza, termed 'influenza-associated pulmonary aspergillosis' (IAPA). AIMS: To assess the morbidity and mortality of critically ill influenza patients with and without IAPA. METHODS: PubMed, Cochrane Library, Scopus and Embase databases were searched for studies containing comparative data of critically ill influenza patients with IAPA. Primary outcomes were all-cause in-hospital and intensive care unit (ICU) mortality. Secondary outcomes were clinical characteristics; duration of invasive mechanical ventilation (IMV); ICU and hospital length of stay (LOS); and requirement for vasopressor, renal replacement therapy (RRT) and extracorporeal membrane oxygenation (ECMO). FINDINGS: The incidence of IAPA was 28.8% in 853 critically ill influenza patients, with an overall mortality rate of 33.4%. No differences in age and comorbidities were observed. Patients with IAPA were predominantly male and received chronic corticosteroids. In-hospital (49.2% vs 27.0%; P=0.002) and ICU (46.8% vs 20.8%; P<0.001) mortality rates were higher among patients with IAPA than in patients without IAPA. A greater proportion of patients with IAPA required IMV, and had a prolonged IMV duration (mean 17.3 vs 10.5 days; P<0.001), ICU LOS (mean 26.8 vs 12.8 days; P=0.001) and hospital LOS (mean 38.7 vs 27.0 days; P=0.003). Patients with IAPA had greater disease severity and were significantly more likely to require vasopressor (76.4% vs 57.9%; P<0.001), RRT (45.7% vs 19.1%; P<0.001) and ECMO (25.9% vs 12.8%; P=0.004) support compared with patients without IAPA. CONCLUSIONS: A diagnosis of IAPA in critically ill patients is associated with greater morbidity and mortality. Early recognition and more research are needed to determine better diagnostic and treatment strategies.

Rosiglitazone Requires Hepatocyte PPARγ Expression to Promote Steatosis in Male Mice With Diet-Induced Obesity.

Thiazolidinediones (TZD) are peroxisome proliferator-activated receptor γ (PPARγ) agonists that may reduce hepatic steatosis through their effects in adipose tissue and therefore have been assessed as potential therapies to treat nonalcoholic fatty liver disease (NAFLD) in humans. However, some studies suggest that expression and activation of hepatocyte PPARγ promotes steatosis and that would limit the benefits of TZD as a NAFLD therapy. To further explore this possibility, we examined the impact of short-term rosiglitazone maleate treatment after the development of moderate or severe diet-induced obesity, in both control and adult-onset hepatocyte-specific PPARγ knockout (PpargΔHep) mice. Independent of the level of obesity and hepatic PPARγ expression, the TZD treatment enhanced insulin sensitivity, associated with an increase in white adipose tissue (WAT) fat accumulation, consistent with clinical observations. However, TZD treatment increased hepatic triglyceride content only in control mice with severe obesity. Under these conditions, PpargΔHep reduced diet-induced steatosis and prevented the steatogenic effects of short-term TZD treatment. In these mice, subcutaneous WAT was enlarged and associated with increased levels of adiponectin, while hepatic levels of phosphorylated adenosine 5'-monophosphate-activated protein kinase were also increased. In addition, in mice with severe obesity, the expression of hepatic Cd36, Cidea, Cidec, Fabp4, Fasn, and Scd-1 was increased by TZD in a PPARγ-dependent manner. Taken together, these results demonstrate that hepatocyte PPARγ expression offsets the antisteatogenic actions of TZD in mice with severe obesity. Therefore, in obese and insulin resistant humans, TZD-mediated activation of hepatocyte PPARγ may limit the therapeutic potential of TZD to treat NAFLD.

Incidence, diagnosis and outcomes of COVID-19-associated pulmonary aspergillosis (CAPA): a systematic review.

COVID-19-associated pulmonary aspergillosis (CAPA) is defined as invasive pulmonary aspergillosis occurring in COVID-19 patients. The purpose of this review was to discuss the incidence, characteristics, diagnostic criteria, biomarkers, and outcomes of hospitalized patients diagnosed with CAPA. A literature search was performed through Pubmed and Web of Science databases for articles published up to 20th March 2021. In 1421 COVID-19 patients, the overall CAPA incidence was 13.5% (range 2.5-35.0%). The majority required invasive mechanical ventilation (IMV). The time to CAPA diagnosis from illness onset varied between 8.0 and 16.0 days. However, the time to CAPA diagnosis from intensive care unit (ICU) admission and IMV initiation ranged between 4.0-15.0 days and 3.0-8.0 days. The most common diagnostic criteria were the modified AspICU-Dutch/Belgian Mycosis Study Group and IAPA-Verweij et al. A total of 77.6% of patients had positive lower respiratory tract cultures, other fungal biomarkers of bronchoalveolar lavage and serum galactomannan were positive in 45.3% and 18.2% of patients. The CAPA mortality rate was high at 48.4%, despite the widespread use of antifungals. Lengthy hospital and ICU stays ranging between 16.0-37.5 days and 10.5-37.0 days were observed. CAPA patients had prolonged IMV duration of 13.0-20.0 days. The true incidence of CAPA likely remains unknown as the diagnosis is limited by the lack of standardized diagnostic criteria that rely solely on microbiological data with direct or indirect detection of Aspergillus in respiratory specimens, particularly in clinical conditions with a low pretest probability. A well-designed, multi-centre study to determine the optimal diagnostic approach for CAPA is required.

Whole genome sequencing data of multiple individuals of Pakistani descent.

Here we report whole genome sequencing of four individuals (H3, H4, H5, and H6) from a family of Pakistani descent. Whole genome sequencing yielded 1084.92, 894.73, 1068.62, and 1005.77 million mapped reads corresponding to 162.73, 134.21, 160.29, and 150.86 Gb sequence data and 52.49x, 43.29x, 51.70x, and 48.66x average coverage for H3, H4, H5, and H6, respectively. We identified 3,529,659, 3,478,495, 3,407,895, and 3,426,862 variants in the genomes of H3, H4, H5, and H6, respectively, including 1,668,024 variants common in the four genomes. Further, we identified 42,422, 39,824, 28,599, and 35,206 novel variants in the genomes of H3, H4, H5, and H6, respectively. A major fraction of the variants identified in the four genomes reside within the intergenic regions of the genome. Single nucleotide polymorphism (SNP) genotype based comparative analysis with ethnic populations of 1000 Genomes database linked the ancestry of all four genomes with the South Asian populations, which was further supported by mitochondria based haplogroup analysis. In conclusion, we report whole genome sequencing of four individuals of Pakistani descent.

Volume reduction of caudate nucleus is associated with movement coordination deficits in patients with hippocampal atrophy due to perinatal hypoxia-ischaemia.

Acute sentinel hypoxia-ischaemia in neonates can target the hippocampus, mammillary bodies, thalamus, and the basal ganglia. Our previous work with paediatric patients with a history of hypoxia-ischaemia has revealed hippocampal and diencephalic damage that impacts cognitive memory. However, the structural and functional status of other brain regions vulnerable to hypoxia-ischaemia, such as the basal ganglia, has not been investigated in these patients. Furthermore, it is not known whether there are any behavioural sequelae of such damage, especially in patients with no diagnosis of neurological disorder. Based on the established role of the basal ganglia and the thalamus in movement coordination, we studied manual motor function in 20 participants exposed to neonatal hypoxia-ischaemia, and a group of 17 healthy controls of comparable age. The patients' handwriting speed and accuracy was within the normal range (Detailed Assessment of Speed of Handwriting), and their movement adaptation learning (Rotary Pursuit task) was comparable to the control group's performance. However, as a group, patients showed an impairment in the Grooved Pegboard task and a trend for impairment in speed of movement while performing the Rotary Pursuit task, suggesting that some patients have subtle deficits in fine, complex hand movements. Voxel-based morphometry and volumetry showed bilateral reduction in grey matter volume of the thalamus and caudate nucleus. Reduced volumes in the caudate nucleus correlated across patients with performance on the Grooved Pegboard task. In summary, the fine movement coordination deficit affecting the hand and the wrist in patients exposed to early hypoxic-ischaemic brain injury may be related to reduced volumes of the caudate nucleus, and consistent with anecdotal parental reports of clumsiness and coordination difficulties in this cohort.

Effect of progestogen for women with threatened miscarriage: a systematic review and meta-analysis.

BACKGROUND: Threatened miscarriage is a common complication of pregnancy. Results of randomised controlled trials on the efficacy of progestogen in the treatment of threatened miscarriage remain inconsistent. OBJECTIVE: To investigate whether the use of progestogen is associated with improved event rate of live birth and other benefits in women with threatened miscarriage. SEARCH STRATEGY: Ovid MEDLINE, Ovid Embase and Cochrane CENTRAL Register of Controlled Trials from their inception until 8 July 2019. SELECTION CRITERIA: Randomised controlled trials comparing progestogen with a placebo or no treatment for pregnancy outcomes in women with threatened miscarriage. DATA COLLECTION AND ANALYSIS: Two authors independently conducted data extraction and assessed study quality. We calculated risk ratios (RR) and 95% confidence intervals using the Mantel-Haenszel approach for dichotomous outcomes. MAIN RESULTS: Ten trials with a total of 5056 participants were eligible for analysis. The use of progesterone increased the incidence of live birth (RR 1.07, 95% CI 1.00-1.15; P = 0.04; I2  = 18%), with benefit only seen with the use of oral progestogen (RR 1.17, 95% CI 1.04-1.31; P = 0.008; I2  = 0%) and not with vaginal progesterone (RR 1.04, 95% CI 1.00-1.08; P = 0.07; I2  = 0%). Similarly, progestogen reduced the risk of miscarriage (RR 0.73, 95% CI 0.59-0.92), with benefit only seen with oral progestogen and not with vaginal progesterone. CONCLUSION: Progestogens may have benefits on live birth rate and miscarriage rate for women with threatened miscarriage. These benefits appear to be confined to the use of oral progestogen, and no statistically significant improvements were seen with vaginal progesterone. TWEETABLE ABSTRACT: A meta-analysis of 10 trials found that progestogens increased live birth rates and reduced miscarriage rates for women with threatened miscarriage.

Women in interventional radiology: insights into Australia's gender gap.

AIM: To assess differences in the exposure, teaching, knowledge, appreciation, and interest in interventional radiology (IR) between male and female doctors prior to specialisation and to identify potential predisposing factors to the gender inequality in interventional radiology. MATERIALS AND METHODS: A prospective cross-sectional multicentre study was conducted using in-person and web-based distribution of a voluntary, anonymous questionnaire to junior doctors yet to commence specialisation at 11 health services across two Australian states. RESULTS: Complete responses were provided by 333 junior doctors (21.9% response rate). Women were significantly less likely than men to consider a career in IR (13.1% versus 29.7%, p < 0.001). No other statistically significant gender disparities were identified, as both men and women reported low levels of prior teaching and exposure to IR, strong belief in the importance of IR, and suboptimal knowledge of IR. CONCLUSIONS: The gender gap amongst practising Australian interventional radiologists is perpetuated by a consistent gender gap in upcoming junior doctors' desire to pursue IR. This disparity exists despite junior doctors receiving the same exposure and opportunities in interventional radiology, possibly suggesting that preconceived stereotypes or psychosocial factors deter females from pursuing this procedural, male-dominated subspecialty. Future qualitative studies are required to confirm this hypothesis, in conjunction with prospective, experimental trials to determine whether changes in education, mentorship, and advocacy can promote gender equality.

Applying Telehealth Technologies and Strategies to Provide Acute Care Consultation and Treatment of Patients With Confirmed or Possible COVID-19.

BACKGROUND AND PURPOSE: The COVID-19 pandemic continues to grow, with 19% of total confirmed patients classified as severe or critical experiencing complications such as dyspnea, hypoxia, acute respiratory distress syndrome, or multiorgan failure. These complications require rehabilitative care. Considering the contagious nature of COVID-19 and the necessity to decrease the volume of health care professionals entering confirmed COVID-19 patient rooms and becoming a potential disease vector, can audiovisual technologies employed by telehealth and telerehabilitation help? CASE DESCRIPTION: This case discusses the Baylor Scott and White Institute for Rehab (BSWIR) Physical Medicine and Rehabilitation (PMR) department COVID-19 acute care therapy team's creation of a telehealth strategy to provide early rehabilitative intervention without increasing the odds of disease transmission. OUTCOMES: The COVID-19 therapy team created a simple process for identifying and triaging care for patients with possible or confirmed COVID-19. These patients were evaluated and treated by the dedicated team using telehealth strategies. A structured risk-benefit analysis was used to determine when in-room care was indicated. DISCUSSION: Acute care physical therapy, occupational therapy, and speech-language pathology telehealth strategies can add value by mitigating COVID-19-related harm and influencing recovery, while not unnecessarily becoming additional disease vectors consuming personal protective equipment. COVID-19 is not only an aggressive respiratory illness similar to acute respiratory distress syndrome but also highly contagious and a risk for health care providers. Telehealth strategies allow therapists to intervene early, opening the possibility to maximize recovery and prevent harm or decompensation. Telehealth strategies can be more prevention-focused while the patient is experiencing relatively good health with goals to maximize strength and endurance before the disease process evolves to critical illness. As COVID-19 progresses, therapy can help mitigate potential complications associated with prolonged intensive care unit stay and ventilator management.

Magnetic resonance imaging pattern recognition in childhood bilateral basal ganglia disorders.

Bilateral basal ganglia abnormalities on MRI are observed in a wide variety of childhood disorders. MRI pattern recognition can enable rationalization of investigations and also complement clinical and molecular findings, particularly confirming genomic findings and also enabling new gene discovery. A pattern recognition approach in children with bilateral basal ganglia abnormalities on brain MRI was undertaken in this international multicentre cohort study. Three hundred and five MRI scans belonging to 201 children with 34 different disorders were rated using a standard radiological scoring proforma. In addition, literature review on MRI patterns was undertaken in these 34 disorders and 59 additional disorders reported with bilateral basal ganglia MRI abnormalities. Cluster analysis on first MRI findings from the study cohort grouped them into four clusters: Cluster 1-T2-weighted hyperintensities in the putamen; Cluster 2-T2-weighted hyperintensities or increased MRI susceptibility in the globus pallidus; Cluster 3-T2-weighted hyperintensities in the globus pallidus, brainstem and cerebellum with diffusion restriction; Cluster 4-T1-weighted hyperintensities in the basal ganglia. The 34 diagnostic categories included in this study showed dominant clustering in one of the above four clusters. Inflammatory disorders grouped together in Cluster 1. Mitochondrial and other neurometabolic disorders were distributed across clusters 1, 2 and 3, according to lesions dominantly affecting the striatum (Cluster 1: glutaric aciduria type 1, propionic acidaemia, 3-methylglutaconic aciduria with deafness, encephalopathy and Leigh-like syndrome and thiamine responsive basal ganglia disease associated with SLC19A3), pallidum (Cluster 2: methylmalonic acidaemia, Kearns Sayre syndrome, pyruvate dehydrogenase complex deficiency and succinic semialdehyde dehydrogenase deficiency) or pallidum, brainstem and cerebellum (Cluster 3: vigabatrin toxicity, Krabbe disease). The Cluster 4 pattern was exemplified by distinct T1-weighted hyperintensities in the basal ganglia and other brain regions in genetically determined hypermanganesemia due to SLC39A14 and SLC30A10. Within the clusters, distinctive basal ganglia MRI patterns were noted in acquired disorders such as cerebral palsy due to hypoxic ischaemic encephalopathy in full-term babies, kernicterus and vigabatrin toxicity and in rare genetic disorders such as 3-methylglutaconic aciduria with deafness, encephalopathy and Leigh-like syndrome, thiamine responsive basal ganglia disease, pantothenate kinase-associated neurodegeneration, TUBB4A and hypermanganesemia. Integrated findings from the study cohort and literature review were used to propose a diagnostic algorithm to approach bilateral basal ganglia abnormalities on MRI. After integrating clinical summaries and MRI findings from the literature review, we developed a prototypic decision-making electronic tool to be tested using further cohorts and clinical practice.
