Abstract
INTRODUCTION Women with atypical hyperplasia (AH) or lobular carcinoma in situ (LCIS) have a significantly increased risk of breast cancer, which can be substantially reduced with antiestrogen therapy for chemoprevention. However, antiestrogen therapy for breast cancer risk reduction remains underutilized. Improving knowledge about breast cancer risk and chemoprevention among high-risk patients and their healthcare providers may enhance informed decision-making about this critical breast cancer risk reduction strategy. METHODS/DESIGN We are conducting a cluster randomized controlled trial to evaluate the effectiveness and implementation of patient and provider decision support tools to improve informed choice about chemoprevention among women with AH or LCIS. We have cluster randomized 26 sites across the U.S. through the SWOG Cancer Research Network. A total of 415 patients and 200 healthcare providers are being recruited. They are assigned to standard educational materials alone or combined with the web-based decision support tools. Patient-reported and clinical outcomes are assessed at baseline, after a follow-up visit at 6 months, and yearly for 5 years. The primary outcome is chemoprevention informed choice after the follow-up visit. Secondary endpoints include other patient-reported outcomes, such as chemoprevention knowledge, decision conflict and regret, and self-reported chemoprevention usage. Barriers and facilitators to implementing decision support into clinic workflow are assessed through patient and provider interviews at baseline and mid-implementation. RESULTS/DISCUSSION With this hybrid effectiveness/implementation study, we seek to evaluate if a multi-level intervention effectively promotes informed decision-making about chemoprevention and provide valuable insights on how the intervention is implemented in U.S. CLINICAL SETTINGS TRIAL REGISTRATION NCT04496739.

Abstract
Hybrid pixel detectors have become indispensable at synchrotron and X-ray free-electron laser facilities thanks to their large dynamic range, high frame rate, low noise, and large area. However, at energies below 3 keV, the detector performance is often limited because of the poor quantum efficiency of the sensor and the difficulty in achieving single-photon resolution due to the low signal-to-noise ratio. In this paper, we address the quantum efficiency of silicon sensors by refining the design of the entrance window, mainly by passivating the silicon surface and optimizing the dopant profile of the n+ region. We present the measurement of the quantum efficiency in the soft X-ray energy range for silicon sensors with several process variations in the fabrication of planar sensors with thin entrance windows. The quantum efficiency for 250 eV photons is increased from almost 0.5% for a standard sensor to up to 62% as a consequence of these developments, comparable to the quantum efficiency of backside-illuminated scientific CMOS sensors. Finally, we discuss the influence of the various process parameters on quantum efficiency and present a strategy for further improvement.

Abstract
BACKGROUND Almost a quarter of children and young people (CYP) in England have a long-term health condition (LTC), which increases the risk of developing mental health difficulties. There is a lack of understanding regarding the routine provision and efficacy of mental health interventions for CYP with LTCs within Children and Young People's Mental Health Services (CYPMHS). METHODS This study analysed national service-reported data in England from two secondary datasets. Data were submitted by services between 2011 and 2019. We evaluated data on the presence or absence of a serious physical health or neurological issue, and which interventions were offered. RESULTS A total of 789 CYP had serious physical health issues and 635 had neurological issues. The most common interventions delivered to CYP in either group have some evidence in the literature. Most CYP showed improvements across a range of outcomes. CONCLUSIONS This study found that prevalence rates and psychological intervention and outcome data were widely under-reported across both datasets, posing questions about their utility for this population. Such data would benefit from triangulation with data from other sources to understand pathways of care for these young people and the extent to which clinical datasets underreport the number of CYP with LTCs.

Abstract
PURPOSE/OBJECTIVE(S) To characterize circulating tumor cell (CTC) kinetics in response to definitive therapy in patients with local or locoregional lung cancer and identify CTC kinetic profiles associated with favorable disease response versus progression. MATERIALS/METHODS In this single-institution prospective correlative biomarker study, we enrolled patients receiving definitive intent radiotherapy (RT) or chemoradiotherapy for non-metastatic lung cancer. Blood specimens were collected prior to RT (baseline), during RT and at follow up visits up to 24 months post RT. Subsequent lines of therapy were administered per standard of care. CTCs were captured and enumerated using a previously reported nanotechnology-based assay functionalized with aEpCAM, aHER-2, and aEGFR to facilitate biomimetic cell rolling and dendrimer-mediated multivalent binding. Disease status was assessed per RECIST 1.1 criteria. CTC kinetics and absolute values were analyzed to identify patterns associated with disease control versus progression. RESULTS We enrolled 24 patients with median follow up of 8 months corresponding to 114 CTC measurements. Seven patients (30%) had biopsy proven disease, while 17 (70%) were diagnosed based on clinical and radiographic features alone. Nineteen patients (79%) received stereotactic body radiation therapy. Median baseline CTC count was 12.6 CTCs/ml (range 0-290) and post RT decreased to median 4 CTCs/ml (0-42.7). For 95% of patients, a favorable kinetic profile (defined as stable CTC count, decreased CTC count or <24 CTCs/ml corresponding to the 80th percentile) during radiotherapy or at the time of first follow up corresponded to local control of the irradiated lesion. Five patients (20%) experienced disease progression within the follow up period. In the two patients with local progression of the irradiated lesion, the CTC count rose >10 fold prior to or at the time of radiographic detection of progression. In the three patients with systemic progression, CTC count rose 1.46-5.8-fold at the time of progression. Notably, four of the five patients with disease progression did not have initial biopsy confirmation of disease but did experience a CTC elevation at the time of progression. CONCLUSION Our data suggests CTCs may serve as a biomarker for response to therapy in patients being treated with RT with definitive intent for early stage or locally advanced lung cancer. This finding is of importance given important limitations in obtaining pathologic confirmation of disease in select patients and challenges distinguishing disease progression versus benign post radiotherapy radiographic changes. Further studies are needed to characterize the predictive and prognostic value of circulating biomarker levels and kinetics in lung cancer.

Abstract
Susac syndrome (SS) is a rare microangiopathy affecting the precapillary arterioles of the brain, inner ear, and retina. We present a novel case of SS, presenting as acute incomplete bitemporal field loss in addition to temporally spaced neurological and vestibulocochlear symptoms. A 39-year-old female was referred to the ophthalmology clinic with acute incomplete bitemporal hemianopia and worsening hemicrania. History revealed progressive hearing loss, subjective short-term memory impairment, and vertigo temporally spaced over the preceding 12 months. Magnetic resonance brain revealed multiple small colosal lesions and liner 'spoke' lesions. Fundus fluorescein angiography revealed multiple branch retinal artery occlusions in the right eye. Audiometry confirmed bilateral sensorineural hearing loss. Treatment included intravenous corticosteroids and rituximab. This case highlights the importance of early consideration and evaluation of SS in individuals presenting with atypical ocular disturbances, where no clear cause can be elicited, in order to limit the sequelae of disease.

Abstract
Development can be altered to match phenotypes with the environment, and the genetic mechanisms that direct such alternative phenotypes are beginning to be elucidated. Yet, the rules that govern environmental sensitivity vs. invariant development, and potential epigenetic memory, remain unknown. Here, we show that plasticity of nematode mouth forms is determined by histone 4 lysine 5 and 12 acetylation (H4K5/12ac). Acetylation in early larval stages provides a permissive chromatin state, which is susceptible to induction during the critical window of environmental sensitivity. As development proceeds deacetylation shuts off switch gene expression to end the critical period. Inhibiting deacetylase enzymes leads to fixation of prior developmental trajectories, demonstrating that histone modifications in juveniles can carry environmental information to adults. Finally, we provide evidence that this regulation was derived from an ancient mechanism of licensing developmental speed. Altogether, our results show that H4K5/12ac enables epigenetic regulation of developmental plasticity that can be stored and erased by acetylation and deacetylation, respectively.

Abstract
OBJECTIVES Acute kidney injury (AKI) is a well-known but poorly documented adverse effect of non-steroidal anti-inflammatory drugs (NSAIDs) in cats. We aimed to describe instances of NSAID-associated AKI in cats and survey Australian veterinarians on NSAID use in acute settings. METHODS Medical records of cats that developed an AKI subsequent to the administration of meloxicam were obtained by searching the databases of seven practices in Queensland, as well as by contemporaneously contacting select veterinary colleagues of the authors in both general and specialist small animal practice. An online questionnaire was created for the survey, and the URL distributed to Australian practitioners. RESULTS A total of 18 cases were retrieved, all of which received injectable meloxicam. The indication(s) for its use and the dosage prescribed were within the manufacturer's recommendations for Australian veterinarians. The majority of cases (13/18 cats) received the label dose of 0.3 mg/kg subcutaneously (SC) on the day of the procedure. In 12/18 cats, the injection was given in association with general anaesthesia or sedation. Fourteen cats survived to hospital discharge. Of 187 survey respondees, 89% routinely administered NSAIDs for surgery-related analgesia, with 98% prescribing meloxicam and 84% of these giving it SC. Ninety percent of respondees routinely administered NSAIDs for non-surgical-related analgesia, with 99% prescribing meloxicam and 35% of those giving it SC. CONCLUSIONS AND RELEVANCE We strongly recommend that practitioners avoid prescribing meloxicam SC in cats. This recommendation is emphatic in situations where concurrent dehydration and/or hypotension are possible.

Abstract
Background: Ibrexafungerp is a novel antifungal treatment for acute vulvovaginal candidiasis (VVC). Using pooled data from two phase three studies (VANISH 303 and 306) in the treatment of acute VVC, this analysis sought to determine the effectiveness of ibrexafungerp in various patient subgroups that may impact outcomes. Materials and Methods: Data from VANISH 303 (NCT03734991) and VANISH 306 (NCT03987620) evaluating ibrexafungerp 300 mg twice daily (BID) for 1 day versus placebo, were pooled and analyzed to determine clinical cure rate, clinical improvement, and mycological cure at the test-of-cure visit (day 11 ± 3) and symptom resolution at the follow-up visit (day 25 ± 4) in the overall population. Patient subgroups analyzed included race, body mass index (BMI), baseline vulvovaginal signs and symptoms (VSS) score, and Candida species. Results: At the test-of-cure visit, patients receiving ibrexafungerp, compared with those who received placebo, had significantly higher rates of clinical cure (56.9% [214/376 patients] vs. 35.7% [65/182 patients]), clinical improvement (68.4% [257/376 patients] vs. 45.1% [82/182 patients]), and mycological cure (54.0% [203/376 patients] vs. 24.2% [44/182 patients]; all p < 0.0001). At the follow-up visit, patients receiving ibrexafungerp had sustained responses with higher symptom resolution rates (66.8% [251/376 patients]) versus placebo (48.4% [88/182 patients]; p < 0.0001). Race, BMI, baseline VSS score (including VSS severity score 13-18), and Candida species infection did not adversely affect clinical cure rates. Safety analysis results were consistent with the individual studies. Conclusions: Ibrexafungerp provides a safe and well-tolerated first-in-class fungicidal, 1-day oral treatment for patients with acute VVC, the first new therapy in >20 years. Clinical Trial Registration Number: NCT03734991.

Abstract
The epidermal growth factor receptor (EGFR) is a transmembrane protein with tyrosine kinase signaling activity regulating many essential cellular functions, and loss of function mutations in EGFR result in a life-threatening neonatal syndrome. We present the case of a preterm boy born with intrauterine growth restriction who developed multisystem disease due to a homozygous mutation in the EGFR gene. He experienced a tumultuous and complex clinical course with recurrent skin infections and sepsis, nephrocalcinosis, failure to thrive, severe electrolyte imbalances, rectal perforation, and thrombus formation, and died after 11 months due to renal failure. This case report builds on work recently published in 2020 describing a case series of 18 similar patients and adds to the growing literature describing the severe phenotype and multisystem disease associated with loss of EGFR mutation in the Roma population.

Abstract
Background There are limited oral treatment options for patients with fungal infections who fail currently available antifungals or have an infection caused by resistant organisms. Ibrexafungerp is an investigational broad-spectrum glucan synthase inhibitor with activity against Candida and Aspergillus species, including azole- and echinocandin-resistant strains. A Phase 3 open-label, single-arm study of ibrexafungerp (FURI; NCT03059992) is ongoing for the treatment of patients intolerant of, or with fungal disease refractory to, standard antifungal therapy. We present an interim analysis of patient outcomes from the FURI study by fungal disease type. Methods FURI patients are eligible for enrollment if they have proven or probable: severe mucocutaneous candidiasis, invasive candidiasis, chronic or invasive aspergillosis, with documented evidence of failure, intolerance, or toxicity related to a currently approved standard-of-care antifungal treatment; or patients who cannot receive approved oral antifungal options (e.g., due to susceptibility), and continued IV antifungal therapy is clinically undesirable or unfeasible. Results An independent Data Review Committee (DRC) provided an assessment of treatment response for 113 enrolled patients in the FURI study from 27 centers in US, UK and EU treated with ibrexafungerp for mucocutaneous or invasive fungal infections from 2016–2021. Fifty-six patients (49.5%) had invasive candidiasis/candidemia, 32 (28.3%) had mucocutaneous candidiasis, 14 (12.4%) had vulvovaginal candidiasis (VVC), and 11 (9.7%) patients had aspergillosis. Upon DRC review, the percent of patients with complete or partial response, or for VVC, clinical improvement (defined as vulvovaginal signs and symptoms score ≤ 1) was 58.4%; stable disease was 23.9%; and 11.5% had disease progression (including 2 VVC patients not meeting the criteria for clinical improvement). There was 1 death due to underlying causes, and 6 outcomes were indeterminate. The table presents outcomes by disease type. Conclusion Analysis of 113 patients from the FURI study indicates that oral ibrexafungerp provides a favorable therapeutic response in patients with challenging fungal disease and limited treatment options.

Abstract
Background There are limited oral antifungal treatment options for patients with high-mortality fungal infections such as candidemia or invasive candidiasis who fail available antifungals or have infection caused by resistant fungi. Ibrexafungerp is a broad-spectrum glucan synthase inhibitor with activity against Candida spp., including azole- and echinocandin-resistant strains. A Phase 3 open-label study of ibrexafungerp (FURI; NCT03059992) is ongoing for patients intolerant of, or invasive fungal disease refractory to, standard antifungal therapy. We present an interim analysis of all-cause mortality (ACM) through 30 d post-treatment for patients with candidemia or invasive candidiasis (IC) who completed therapy up until Oct 2020. Methods FURI patients are eligible for enrollment with proven/probable severe mucocutaneous candidiasis or IC, or candidemia, with documented evidence of failure, intolerance, or toxicity related to an approved standard-of-care antifungal treatment; or patients who cannot receive oral antifungals (e.g., due to susceptibility), and continued IV antifungal therapy is clinically undesirable/unfeasible. Patients were followed through 30 d post-treatment for ACM. Results Out of the 74 patients who completed therapy in the FURI study through October 2020, 39 (52.7%) had IC or candidemia and received ibrexafungerp. The most common infections in this group were candidemia (28.2%), intra-abdominal infection (28.2%), and bone infection (20.5%). Survival at ≥ 30 d post-treatment was 92.3%. Three patients (7.7%) died within 30 d post ibrexafungerp, a 4th died at 31 d, and a 5th died at 56 d. The mean age of the expired patients was 54 yr. Three patients had candidemia (2 with C. parapsilosis and 1 with C. albicans), and 2 had intra-abdominal candidiasis, (both with C. glabrata). The average time on ibrexafungerp was 16.6 d. The mean time to death post-treatment for these patients was 22 d (median 8 d). In each case, the deaths were due to causes other than the underlying fungal disease. Conclusion Analysis of all-cause mortality in these patients from the FURI study indicates that oral ibrexafungerp provides a favorable therapeutic response in patients with challenging fungal disease and limited treatment options.

Background
There are limited oral treatment options for patients with high-mortality fungal infections such as candidemia or invasive candidiasis who fail currently available antifungals or have an infection caused by resistant organisms. Ibrexafungerp is an investigational broad-spectrum glucan synthase inhibitor with activity against Candida species, including azole- and echinocandin-resistant strains. A Phase 3 open-label, single-arm study of ibrexafungerp (FURI; NCT03059992) is ongoing for the treatment of patients intolerant of, or with invasive fungal disease refractory to, standard antifungal therapy. We present an interim analysis of all-cause mortality within 30 days post-treatment from the FURI study by fungal disease type for patients with candidemia or invasive candidiasis, who completed therapy up until October 2021.
Methods
FURI patients are eligible for enrolment if they have proven or probable: severe mucocutaneous candidiasis or invasive candidiasis, or candidemia, with documented evidence of failure, intolerance, or toxicity related to a currently approved standard-of-care antifungal treatment; or patients who cannot receive approved oral antifungal options (eg, due to susceptibility), and continued IV antifungal therapy is clinically undesirable or unfeasible. Patients were followed through 30 days post-treatment for all-cause mortality.
Results
Out of the 113 patients who completed therapy in the FURI study through October 2021, 56 (50%) had invasive candidiasis or candidemia and were treated with ibrexafungerp. The most common infections in this group were candidemia (15/56, 26.8%), intra-abdominal infection (13/56, 23.2%), and bone infection (10/56, 17.9%).
Overall survival within 30 days post-treatment in this group of 56 patients was 94.6%. Of the 56 patients with candidemia or invasive candidiasis, three (5.3%) died within 30 days after completion of treatment with ibrexafungerp, a fourth died at 31 days, a fifth died at 50 days, and a sixth died at 56 days. The mean age of the expired patients was 56 years. All 4 patients had candidemia (3 with C. parapsilosis and 1 with C. albicans), and 2 had intra-abdominal candidiasis, (both with C. glabrata). The average time on therapy with ibrexafungerp was 15.7 days. The mean time to death post-treatment for these patients was 27 days (median, 21 days). In five cases, the deaths were due to causes other than the underlying fungal disease. For the other case, the cause of death was not disclosed.
Conclusions
Analysis of all-cause mortality in these patients from the FURI study indicates that oral ibrexafungerp provides a favorable therapeutic response in patients with challenging fungal diseases and limited treatment options.

Abstract
Background Anxiety disorders are common among primary-school aged children, but few affected children receive evidence-based treatment. Identifying and supporting children who experience anxiety problems through schools would address substantial treatment access barriers that families and school staff often face. We have worked with families and school staff to co-design procedures that incorporate screening, feedback for parents, and the offer of a brief intervention in primary schools. This study sets out to assess the feasibility of a subsequent school-based cluster randomised controlled trial to evaluate these procedures. Our objectives are to ensure our procedures for identifying and supporting children with anxiety difficulties through primary schools are acceptable and there are no negative impacts, to estimate recruitment and retention rates, and to identify any changes needed to study procedures or measures. Methods We will recruit six primary/junior schools in England (2 classes per school), and invite all children (aged 8–9) (n = 360) and their parent/carer and class teacher in participating classes to take part. Children, parents and class teachers will complete questionnaires at baseline and 12-week follow-up. Children who ‘screen positive’ on a 2-item parent-report child anxiety screen at baseline will be the target population (expected n = 43). Parents receive feedback on screening questionnaire responses, and where the child screens positive the family is offered support (OSI: Online Support and Intervention for child anxiety). OSI is a brief, parent-led online intervention, supported by short telephone sessions with a Children’s Wellbeing Practitioner. Participants’ experiences of study procedures will be assessed through qualitative interviews/discussion groups. Discussion Evidence-based procedures for identifying and supporting children with anxiety difficulties through primary schools would improve children’s access to timely, effective intervention for anxiety difficulties.

Abstract
Urban gardeners contribute to sustainable cities and often take great care to limit exposure to soil contaminants like lead (Pb). Although best management practices (BMPs) like mulching to reduce soil splash can limit crop contamination, they may not eliminate all contamination for leafy greens, which trap soil particles. How effective is washing at removing Pb contamination from leafy greens when using BMPs? Are certain washing techniques more effective than others? We present results from two experiments addressing these questions. We grew lettuce (Lactuca sativa L.) in homogenized high-Pb (∼1,150 mg kg-1 ) and low-Pb (∼90 mg kg-1 ) soils in Brooklyn, NY, and Ithaca, NY. Our results show that washing can remove 75-94% of Pb from lettuce, including that remaining after the use of contamination-reducing BMPs. It was estimated that washing removed 97% of Pb deposited by splash, which is the dominant source of Pb, and removed 91% deposited by downward deposition. All washing techniques were effective at reducing Pb levels, with differences in effectiveness ranked as: commercial soak > vinegar soak > water soak (and water rinse not significantly different from vinegar or water soak). Washing crops grown in low-Pb soils is also important. Without washing, lettuce grown in low-Pb soil may still have Pb levels above the European Commission comparison value. We offer these empirical findings and recommendations in support of urban growers.

Abstract
The preparation of Water-accommodated Fractions (WAFs) and chemically enhanced WAFs (CEWAFs) are essential for evaluating oil toxicity. The Chemical Response to Oil Spills: Ecological Research Forum (CROSERF) method was widely adopted, with variables (e.g., mixing time, oil loading, etc.) being continuously changed among research groups, which limits the cooperation in this area. Herein, we conducted WAF and CEWAF experiments using two loadings of diluted bitumen (Dilbit): 1 g/L and 10 g/L. For the CEWAF, the dispersant to oil ratio was 1:20. We investigated the impact of three mixing durations (18 h, 42 h, and 66 h) and two resting times (6 h and 24 h) on the droplet size distribution (DSD) and accommodated oil concentration. This would be highly beneficial for analyzing toxicity from oil spills, especially when considering the toxic effect of both suspended oil droplets and dissolved hydrocarbons. The DSD results and oil chemistry analysis showed that at a low oil loading concentration (1 g/L), both WAFs and CEWAFs had the same DSD, with an average d50 (volume median diameter) of 3.38 ± 0.70 μm and 3.85 ± 0.63 μm, respectively. At a high oil loading concentration (10 g/L), the WAFs had an average d50 of 3.69 ± 0.52 μm, showing no correlation with mixing and resting time. The DSD of CEWAFs increased significantly at 42 h mixing and 24 h resting time, with oil concentration reaching equilibrium after 42 h mixing. Therefore, WAFs appears to require only 18 h mixing and 6 h resting, while it is recommended to have 42 h mixing and 24 h resting for CEWAFs at high dilbit oil loading concentrations.

Abstract
Microbial degradation is a useful tool for inhibiting or preventing polycyclic aromatic hydrocarbons (PAHs) widely distributed in marine environment after oil spill accidents. This study aimed to evaluate the potential and diversity of bacteria Bacillus sp. PAH-2 on Benzo (a) anthracene (BaA), Pyrene (Pyr), and Benzo (a) pyrene (BaP), their composite system, aromatic components system, and crude oil. The seven-day degradation rates against BaA, Pyr, and BaP were 20.6%, 12.83%, and 17.49%, respectively. Further degradation study of aromatic components demonstrated PAH-2 had a high degradation rate of substances with poor stability of molecular structure. In addition, the degradation of PAHs in crude oil suggested PAH-2 not only made good use of PAHs in such a more complex structure of pollutants but the saturated hydrocarbons in the crude oil also showed a good application potential.

Abstract
INTRODUCTION Primary aldosteronism (PA) is associated with increased risk of cardiovascular events. However, treatment of PA has not been shown to improve left ventricular (LV) systolic function using the conventional assessment with LV ejection fraction (LVEF). We aim to use speckle-tracking echocardiography to assess for improvement in subclinical systolic function after treatment of PA. METHODS We prospectively recruited 57 patients with PA, who underwent 24-h ambulatory blood pressure (BP) measurements and echocardiography, including global longitudinal strain (GLS) assessment of left ventricle, at baseline and 12 months post-treatment. RESULTS At baseline, GLS was low in 14 of 50 (28.0%) patients. On multivariable analysis, GLS was associated with diastolic BP (P = 0.038) and glomerular filtration rate (P = 0.026). GLS improved post-surgery by -2.3, 95% CI: -3.9 to -0.6, P = 0.010, and post-medications by -1.3, 95% CI: -2.6 to 0.03, P = 0.089, whereas there were no changes in LVEF in either group. Improvement in GLS was independently correlated with baseline GLS (P < 0.001) and increase in plasma renin activity (P = 0.007). Patients with post-treatment plasma renin activity ≥1 ng/ml/h had improvements in GLS (P = 0.0019), whereas patients with persistently suppressed renin had no improvement. Post-adrenalectomy, there were also improvements in LV mass index (P = 0.012), left atrial volume index (P = 0.002), and mitral E/e' (P = 0.006), whereas it was not statistically significant in patients treated with medications. CONCLUSION Treatment of hyperaldosteronism is effective in improving subclinical LV systolic dysfunction. Elevation of renin levels after treatment, which reflects adequate reversal of sodium overload state, is associated with better systolic function after treatment.

Abstract
Spilled oil slicks are likely to break into droplets offshore due to wave energy. The fate and transport of such droplets are affected by suspended particles in local marine environment, through forming oil particle aggregates (OPAs). OPA formation is affected by various factors, including the mixing energy and duration. To evaluate these two factors, lab experiments of OPA formation were conducted using kaolinite at two hydrophobicities in baffled flasks, as represented by the contact angle of 28.8° and 37.7° (original and modified kaolinite). Two mixing energies (energy dissipation rates of 0.05 and 0.5 W/kg) and four durations (10 min, 30 min, 3 h, and 24 h) were considered. Penetration to the oil droplets was observed at 3-5 μm and 5-7 μm for the original and modified kaolinite by confocal microscopy, respectively. At lower mixing energy, volume median diameter d50 of oil droplets increased from 45 μm to 60 μm after 24 h mixing by original kaolinite; for modified kaolinite, d50 decreased from 40 μm to 25 μm after 24 h mixing. The trapped oil amount in negatively buoyant OPAs decreased from 35% (3 h mixing) to 17% (24 h mixing) by original kaolinite; and from 18% to 12% after 24 h mixing by modified kaolinite. Results indicated that the negatively buoyant OPAs formed with original kaolinite at low mixing energy reaggregated after 24 h. At higher mixing energy, d50 decreased from 45 μm to 17 μm after 24 h mixing for both kaolinites. And the trapped oil amount in negatively buoyant OPAs increased to 72% and 49% after 24 h mixing for original and modified kaolinite, respectively. At higher mixing energy, the OPAs formed within 10 min and reached equilibrium at 3 h by original kaolinite. For modified kaolinite, the OPAs continued to form through 24 h.

Abstract
The burden of COVID-19 in children represents a fraction of cases worldwide, yet a subset of those infected are at risk for severe disease. We measured plasma SARS-CoV-2 RNA in a cohort of 103 children hospitalized with COVID-19 with diverse clinical manifestations. SARS-CoV-2 RNAemia was detected in 27 (26%) of these children, lasted for a median of 6 [2-9] days, and it was associated with higher rates of oxygen administration, admission to the intensive care unit, and longer hospitalization.

Abstract
Background Diabetes mellitus is associated with inadequate delivery of oxygen to tissues. Cellular hypoxia is associated with mitochondrial dysfunction which increases oxidative stress and hyperglycaemia. Hyperbaric oxygenation therapy, which was shown to improve insulin sensitivity, is impractical for regular use. We evaluated the effects of water which is stably-enriched with oxygen (ELO water) to increase arterial blood oxygen levels, on mitochondrial function in the presence of normal- or high-glucose environments, and as glucose-lowering therapy in humans. Methods We compared arterial blood oxygen levels in Sprague-Dawley rats after 7 days of ad libitum ELO or tap water consumption. Mitochondrial stress testing, and flow cytometry analysis of mitochondrial mass and membrane potential, were performed on human HepG2 cells cultured in four Dulbecco’s Modified Eagle Medium media, made with ELO water or regular (control) water, at normal (5.5 mM) or high (25 mM) glucose concentrations. We also randomized 150 adults with type 2 diabetes (mean age 53 years, glycated haemoglobin HbA1c 8.9% [74 mmol/mol], average duration of diabetes 12 years) to drink 1.5 litres daily of bottled ELO water or drinking water. Results ELO water raised arterial oxygen tension pO2 significantly (335 ± 26 vs. 188 ± 18 mmHg, p = 0.006) compared with tap water. In cells cultured in control water, mitochondrial mass and membrane potential were both significantly lower at 25 mM glucose compared with 5.5 mM glucose; in contrast, mitochondrial mass and membrane potential did not differ significantly at normal or high glucose concentrations in cells cultured in ELO water. The high-glucose environment induced a greater mitochondrial proton leak in cells cultured in ELO water compared to cells cultured in control medium at similar glucose concentration. In type 2 diabetic adults, HbA1c decreased significantly (p = 0.002) by 0.3 ± 0.7% (4 ± 8 mmol/mol), with ELO water after 12 weeks of treatment but was unchanged with placebo. Conclusions ELO water raises arterial blood oxygen levels, appears to have a protective effect on hyperglycaemia-induced reduction in mitochondrial mass and mitochondrial dysfunction, and may be effective adjuvant therapy for type 2 diabetes.

Abstract
Douglas Channel and the adjacent Hecate Strait (British Columbia, Canada) are part of a proposed route to ship diluted bitumen (dilbit). This study presents how two types of dilbit naturally degrade in this environment by using an in situ microcosm design based on dilbit-coated beads. We show that dilbit-associated n-alkanes were microbially biodegraded with estimated half-lives of 57-69 days. n-Alkanes appeared to be primarily degraded using the aerobic alkB, ladA and CYP153 pathways. The loss of dilbit polycyclic aromatic hydrocarbons (PAHs) was slower than of n-alkanes, with half-lives of 89-439 days. A biodegradation of PAHs could not be conclusively determined, although a significant enrichment of the phnAc gene (a marker for aerobic PAH biodegradation) was observed. PAH degradation appeared to be slower in Hecate Strait than in Douglas Channel. Microcosm-associated microbial communities were shaped by the presence of dilbit, deployment location and incubation time but not by dilbit type. Metagenome-assembled genomes of putative dilbit-degraders were obtained and could be divided into populations of early, late and continuous degraders. The majority of the identified MAGs could be assigned to the orders Flavobacteriales, Methylococcales, Pseudomonadales and Rhodobacterales. A high proportion of the MAGs represent currently unknown lineages or lineages with currently no cultured representative.

Abstract
Urban community gardeners employ a range of best practices that limit crop contamination by toxicants like lead (Pb). While Pb root uptake is generally low, the relative significance of various Pb deposition processes and the effectiveness of best practices in reducing these processes have not been sufficiently characterized. This study compared leafy lettuce (Lactuca sativa) grown in high Pb (1150 mg/kg) and low Pb (90 mg/kg) soils, under three different soil cover conditions: 1) bare soil, 2) mulch cover to limit splash, and 3) mulch cover under hoophouses to limit splash and air deposition, in a New York City (NYC) community garden and a rural site in Ithaca, New York (NY). The lettuces were further compared to greenhouse (Ithaca) and supermarket (NYC) samples. Atmospheric deposition was monitored by passive trap collection through funnel samplers. Results show that in low Pb soils, splash and atmospheric deposition accounted for 84 and 78% of lettuce Pb in NYC and Ithaca, respectively. In high Pb soils, splash and atmospheric deposition accounted for 88 and 93% of Pb on lettuces, with splash being the dominant mechanism. Soil covers were shown to be effective at significantly (p < 0.05) reducing lettuce Pb contamination, and mulching is strongly recommended as a best practice.

Abstract
The aim of this study was to investigate whether gender was an effect modifier of the relationship between three psychosocial job stressors and sleep quality, in a representative sample of 7280 employed Australians. We conducted linear regressions and effect measure modification analyses. Low job control, high job demands and low job security were associated with poorer sleep quality. There was evidence of effect modification of the relationship between job security and sleep quality by gender on the additive scale, indicating that the combined effect of being male and having low job security is greater than the summed interactive effect.

Abstract
Abstract
Introduction
The commonest cause of stress urinary incontinence in men is radical prostatectomy. We aimed to determine the efficacy, complication rate and need for salvage surgery in the medium-long term for male sling insertion.
Method
Retrospective review of all patients undergoing male sling insertion at one centre between 2009-2018. Data was collected on complications, patient satisfaction and need for further surgery. Preoperative severity was categorized as mild, moderate, or severe. We assessed ICIQ score, 24h-pad usage, patient satisfaction and identified risk factors for treatment success/failure.
Results
91 men had slings inserted (median age- 67.3). Three months success rates in mild, moderate and severe SUI groups were 96%, 86% and 80% respectively which dropped to 65%, 62% and 47% in the medium term. The rate of AUS implantation was 6%, 15% and 33% respectively. Complications included pain, infection, retention and OAB. Patient satisfaction at 5-years was 57%. Only factor predicting success or failure was pre-operative ICIQ-UI(SF) score.
Conclusions
Male sling success rates deteriorate over time. 15% will have an AUS. The risk of complications is low and transient. A pre-operative ICIQ-UI(SF) score of > 18 is a predictor of failure. Sling insertion remains a reasonable treatment option for male patients suffering with SUI.

Abstract
Schools worldwide have implemented many different peer-led interventions with mixed results, but the evidence base on their effectiveness as mental health interventions remains limited. This study combines a scoping review and systematic review to map the variations of peer-led interventions in schools and to evaluate the quality of the existing evidence base. This scoping review and systematic review evaluated the existing literature across 11 academic databases. Studies were included if they reported a peer-led intervention that aimed to address a mental health or wellbeing issue using a peer from the same school setting. Data were extracted from published and unpublished reports and presented as a narrative synthesis. 54 studies met eligibility criteria for the scoping review, showing that peer-led interventions have been used to address a range of mental health and wellbeing issues globally. 11 studies met eligibility criteria for the systematic review with a total of 2,239 participants eligible for analysis (929 peer leaders; 1,310 peer recipients). Two studies out of seven that looked at peer leaders showed significant improvements in self-esteem and social stress, with one study showing an increase in guilt. Two studies out of five that looked at peer recipient outcomes showed significant improvements in self-confidence and in a quality of life measure, with one study showing an increase in learning stress and a decrease in overall mental health scores. The findings from these reviews show that despite widespread use of peer-led interventions, the evidence base for mental health outcomes is sparse. There appear to be better documented benefits of participation for those who are chosen and trained to be a peer leader, than for recipients. However, the small number of included studies means any conclusions about effectiveness are tentative.

Abstract
Oil droplets in marine environment interact with particles to form oil particle aggregates (OPA), and alters the transport and fate of oil. We investigated the impact of particles properties on the formation of OPAs. It was found that the distribution of 9 μm spherical silica (sand) particles on the oil droplet was more uniform than the 3 μm silica particles, and it is likely due to the inertia of the larger particles causing them to lodge into the droplet. Also, the OPAs of the 3 μm silica particles were much smaller than those of the 9 μm particles. For kaolinite particles that are rod-like of length around 10 μm, it was found that increasing the hydrophobicity of the particles from a contact angle (CA) of ~ 29o to 38o, increases the penetration of the particles in the oil through a projectile penetration mechanism, whereby the particle possesses sufficient inertia to penetrate into the oil. However, a further increase in hydrophbocitiy (CA ~ 57o) caused the particles to agglomerate together and avoid the oil droplets. The oil droplets got smaller with time probably due to the penetration of the particles in them. For an oil concentration of 500 mg/L, a particle concentration of 100 mg/L was incapable of fragmenting the oil droplets, but particle concentration of 500 mg/L fragmented the droplets similarly to a concentration of 1500 mg/L. This is due to the larger coverage of the droplet surface area by the particles and the subsequent weakening of its structural rigidity through the reduction of the oil-water interfacial tension. The study shows that the fate (e.g., after 24 h) of OPAs greatly depends on the type of sediments where the oil spilled (sand versus clay) and their concentration.

Abstract
INTRODUCTION There is minimal data published on the longevity of the transobturator retrobulbar male sling (AdVance™). We aimed to determine the efficacy, the complication rate and need for salvage SUI surgery in the medium to long term for male sling insertion. MATERIALS AND METHODS We performed a retrospective review of all patients undergoing male sling insertion at a single centre between 2009 and 2018. Data on patient demographics, pre and post-operative International Consultation on Continence Questionnaire - Urinary Incontinence (Short Form) (ICIQ-UI(SF)) scores and 24 h pad usage were collected. Success was calculated as a combination of the cured rate (0-1 security pad use) and the improved rate (>50% reduction in pad usage). Data was also collected on complications, patient satisfaction as well as need for further SUI surgery. RESULTS A total of 91 patients underwent male sling insertion in the period specified; median follow up was 69 months. Success rates at 3 months in mild SUI, moderate SUI and severe SUI groups were 96, 86 and 80%, respectively. In the medium to long term, this drops to 65, 62 and 47%, respectively. The overall rate of artificial urinary sphincter (AUS) implantation was 15%. Common complications included groin pain (3%), infection (3%), urinary retention (10%) and de novo overactive bladder (OAB) (11%). The only factor predicting success or failure was pre-operative ICIQ-UI(SF) score. CONCLUSIONS AdVance™ male sling success rates deteriorate from 89% at 3 months to 61% at 5 years. The risk of complications is low and, for the most part, transient. Sling insertion remains a reasonable treatment option for male patients suffering with stress urinary incontinence (SUI).

Abstract
INTRODUCTION To report the clinical presentation, laboratory and imaging findings, treatment and outcome of abdominal cryptococcosis in dogs and cats in Australia. MATERIALS AND METHODS Canine and feline cases from Australia were retrospectively identified (2000 to 2018) via laboratory and referral centre searches for abdominal cryptococcosis diagnosed by cytology (needle aspirates) or histopathology (biopsy or necropsy) of abdominal organs/tissues. Signalment, presenting complaints, clinical signs, laboratory findings, medical imaging, latex cryptococcal antigen agglutination test (LCAT) titres, treatment and outcome data was collected. RESULTS Thirty-eight cases were included (35 dogs, three cats) in the study. Median age of presentation was 2 years for dogs and 6 years for cats. Common presenting complaints included vomiting (23/38), lethargy (19/38) and inappetence/anorexia (15/38). Abdominal ultrasound (25/38 cases) revealed mesenteric and intestinal lesions in most of the cases. On surgical exploration, seven cases had an intestinal lesion associated with an intussusception. Nineteen cases had a pre-treatment LCAT performed, with a median initial titre of 1:2048 (range 1:2 to 65,536). Twenty-four cases (23 dogs, one cat) received treatment, either medical, surgical or both. Median survival time for cases with combined medical and surgical treatment, surgical treatment alone or medical treatment alone was 730, 140 and 561 days, respectively. Eleven remain alive at the time of follow up. CLINICAL SIGNIFICANCE Abdominal cryptococcosis although rare should be a considered as a diagnostic possibility in an especially young dog presenting with gastro-intestinal signs. Older dogs can also present with this condition and should not be euthanised based on imaging alone due to the likenesses with neoplasia. With appropriate treatment and monitoring many dogs may have a prolonged survival period and some may be cured.

Abstract
BACKGROUND Validated, reliable, globally accepted outcome measurement instruments for hidradenitis suppurativa (HS) are needed. Current tools to measure the physical signs domain for HS rely on lesion counts, which are time-consuming and unreliable. OBJECTIVES To assess the reliability and validity of the Hidradenitis suppurativa Area and Severity Index Revised (HASI-R) tool, a novel method for assessing HS severity, incorporating signs of inflammation and body surface area involved. METHODS The measurement properties of the HASI-R tool were evaluated. The tool was created by combining the previously published HASI and Severity and Area Score for Hidradenitis instruments. Twenty raters evaluated 15 patients with HS in a hospital-based ambulatory dermatology clinic. The objectives of the study were to assess inter- and intra-rater reliability of the HASI-R and its components, as well as its construct and known-groups validity. Existing lesion count-based clinician-reported measures of HS and their components were also assessed. Raters were also asked their preferences regarding the various HS severity assessment tools. RESULTS The HASI-R had moderate inter-rater reliability [intra-class correlation coefficients (ICC) 0·60]. This was better than all other HS physical sign outcome measures evaluated, which had poor inter-rater reliability (ICC < 0·5). HASI-R had the highest intra-rater reliability (ICC 0·91). The HASI-R had good construct validity and demonstrated known-groups validity. The HASI-R was also the most preferred tool by all raters. CONCLUSIONS Results from the clinometric assessment of the HASI-R are encouraging, and support continued evaluation of this clinician-reported outcome measure.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic inflammatory disease. The HS core outcome set calls for a patient global assessment (PtGA). OBJECTIVES To assess the validity, reliability and responsiveness of a candidate single-item PtGA for HS-specific health-related quality of life (HRQoL). METHODS Cognitive debriefing interviews were conducted with patients with HS in Denmark and the USA. A cross-sectional observational study was done with adults with HS in the USA and Denmark. Candidate PtGA item, demographic items and multiple patient-reported scales - the Hidradenitis Suppurativa Quality of Life (HiSQOL), Dermatology Life Quality Index (DLQI) and numerical rating scale (NRS) for pain - were concurrently administered to evaluate convergent and known-groups validity. Scales with a single-item assessment of change were readministered 24-72 h later, to evaluate reliability and responsiveness. RESULTS After cognitive debriefing, the candidate PtGA for HS-specific HRQoL was finalized with five response levels. Convergent validity of the PtGA was supported by significant correlations with HiSQOL score [r = 0·79, 95% confidence interval (CI) 0·75-0·82] and DLQI (r = 0·78, 95% CI 0·74-0·82). The PtGA displayed known-groups validity with DLQI score bands based on significance of an anova (P < 0·001). Good test-retest reliability was supported by the intraclass correlation coefficient (0·82, 95% CI 0·78-0·85) for those who reported stable HS. Responsiveness was assessed by differences in PtGA score against a patient-reported assessment of change, which showed significant differences towards improvement. CONCLUSIONS The single-item PtGA exhibits reliability, validity and responsiveness in assessing HS-specific HRQoL in HS, making it a good provisional tool for HS clinical research.

Abstract
BACKGROUND There is a well-established gender divide among people who do and do not seek professional help from mental health professionals. Females are typically more likely to report, and seek help for, mental health problems. The current paper sought to examine the role of employment context on help-seeking for mental health issues. We hypothesised that men and women in male-dominated occupations would be less likely to seek help than those in non-male-dominated occupations. METHODS Data from the Household, Income and Labour Dynamics in Australia survey were used. Help-seeking, measured in 2013, was defined as whether a person reported attending a mental health professional in the 12 months prior to the survey. The exposure, male- and non-male-dominated occupations (measured in 2012), was defined using census data based on self-reported occupation. Analyses were stratified by gender and controlled for relevant confounders (measured in 2012), including mental health and prior help-seeking. We conducted multivariate logistic and propensity score analyses to improve exchangeability of those exposed and unexposed. RESULTS For males, being in a male-dominated occupation was independently associated with reduced likelihood of help-seeking (OR 0.66, 95% CI 0.46-0.95) in the adjusted model, although this result fell just out of significance in the propensity score analysis. There was no independent effect of being in a male-/non-male-dominated occupation for help-seeking among women. CONCLUSIONS Results suggest that male-dominated occupations may negatively influence help-seeking among males. There is a need for more research to understand this relationship and for workplace-based prevention initiatives.

Abstract
Abstract
A highly sensitive and selective method that requires minimal sample preparation was developed for the confirmation and quantitation of cyclamate in a variety of foods by high-performance liquid chromatography/tandem mass spectrometry (HPLC/MS/MS). Sample preparation consisted of homogenization followed by extraction and dilution of cyclamate with water. HPLC separation was achieved using a bridged ethyl hybrid C18 high-pressure column with a mobile phase consisting of 0.15 acetic acid and methanol. Under electrospray ionization negative conditions, quantitation was achieved by monitoring the fragment m/z 79.7 while also collecting parent ion m/z 177.9. Two food matrixes, diet soda and jelly, were subjected to a validation procedure in order to evaluate the applicability of the method. The cyclamate limit of detection for both matrixes was determined to be 0.050 g/g with a limit of quantitation of 0.150 g/g. The correlation coefficient of the calibration curves was >0.9998 from 0.0005 to 0.100 g/mL. The method has been used for the determination of cyclamate in several foods and the results are presented.

Abstract
MAIT cells are an unconventional T cell population that can be activated through both TCR-dependent and TCR-independent mechanisms. Here, we examined the impact of combinations of TCR-dependent and TCR-independent signals in human CD8+ MAIT cells. TCR-independent activation of these MAIT cells from blood and gut was maximized by extending the panel of cytokines to include TNF-superfamily member TL1A. RNA-seq experiments revealed that TCR-dependent and TCR-independent signals drive MAIT cells to exert overlapping and specific effector functions, affecting both host defense and tissue homeostasis. Although TCR triggering alone is insufficient to drive sustained activation, TCR-triggered MAIT cells showed specific enrichment of tissue-repair functions at the gene and protein levels and in in vitro assays. Altogether, these data indicate the blend of TCR-dependent and TCR-independent signaling to CD8+ MAIT cells may play a role in controlling the balance between healthy and pathological processes of tissue inflammation and repair.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disease with a large impact on patients' health-related quality of life. However, reliable and consistent outcome measures to assess body surface area (BSA) of HS have not been established. OBJECTIVES To develop and assess the reliability and validity of a novel outcome instrument for assessment of HS BSA in a clinical trial setting. METHODS Qualitative interviews and focus groups were conducted from July to August 2015 and October 2017 to January 2018. Evaluation of the measurement was assessed during a single-day grading session with patients in April 2018. Participants, who included clinicians or patients, were recruited from academic medical centres in the U.S. mid-Atlantic region. RESULTS Concept elicitation included input from 10 providers, of which 60% (n = 6) were female, 80% (n = 8) dermatology specialists and 20% (n = 2) gynaecology specialists. Cognitive debriefing was conducted with 11 providers, of which 82% (n = 9) were dermatologists and 18% (n = 2) gynaecologists. The evaluation stage included 10 clinicians and 23 patients. The intraclass correlation coefficient (ICC) for inter-rater reliability was 0·60 [95% confidence interval (CI) 0·44-0·74]. The ICC for intrarater reliability was 0·98 (95% CI 0·94-1·00). Transformation of the BSA score resulted in an increase in inter-rater reliability to 0·75 (95% CI 0·62-0·85) or 0·76 (95% CI 0·62-0·85). Scores all demonstrated concurrent validity, with statistically significant correlations with extant scoring methods. CONCLUSIONS This novel scale is a reliable and valid HS outcome instrument and may capture a wide range of patients by assessing BSA. Future research is necessary to demonstrate its responsiveness. What's already known about this topic? The major HS disease activity scales rely on lesions counts and have moderate-to-good reliability. Body surface area (BSA) is one of the physical signs included in the Core Outcome Set for HS, but is not a part of existing HS disease activity scales. What does this study add? A novel disease severity scale, the Severity and Area Score for Hidradenitis (SASH), was developed and the psychometric properties assessed. There was high inter-rater reliability of 0·75 and 0·76 when BSA was scored on an ordinal scale, and an excellent intrarater reliability of 0·98. The SASH score also demonstrated convergent validity with extant instruments. What are the clinical implications of this work? The ability of clinicians to accurately assess disease status will be improved. Implementation of the SASH score will help guide and assess the effectiveness of appropriate treatment choice.
