Abstract
This study examines the influence of meteorological factors and air pollutants on the performance of automatic pollen monitoring devices, as part of the EUMETNET Autopollen COST ADOPT-intercomparison campaign held in Munich, Germany, during the 2021 pollen season. The campaign offered a unique opportunity to compare all automatic monitors available at the time, a Plair Rapid-E, a Hund-Wetzlar BAA500, an OPC Alphasense, a KH-3000 Yamatronics, three Swisens Polenos, a PollenSense APS, a FLIR IBAC2, a DMT WIBS-5, an Aerotape Sextant, to the average of four manual Hirst traps, under the same environmental conditions. The investigation aimed to elucidate how meteorological factors and air pollution impact particle capture and identification efficiency. The analysis showed coherent results for most devices regarding the correlation between environmental conditions and pollen concentrations. This reflects on one hand, a significant correlation between weather and airborne pollen concentration, and on the other hand the capability of devices to provide meaningful data under the conditions under which measurements were taken. However, correlation strength varied among devices, reflecting differences in design, algorithms, or sensors used. Additionally, it was observed that different algorithms applied to the same dataset resulted in different concentration outputs, highlighting the role of algorithm design in these systems (monitor + algorithm). Notably, no significant influence from air pollutants on the pollen concentrations was observed, suggesting that any potential difference in effect on the systems might require higher air pollution concentrations or more complex interactions. However, results from some monitors were affected to a minor degree by specific weather variables. Our findings suggest that the application of real-time devices in urban environments should focus on the associated algorithm that classifies pollen taxa. The impact of air pollution, although not to be excluded, is of secondary concern as long as the pollution levels are similar to a large European city like Munich.

Abstract
As the severe acute respiratory syndrome coronavirus-2 pandemic has proceeded, ventilation has been recognized increasingly as an important tool in infection control. Many hospitals in Ireland and the UK do not have mechanical ventilation and depend on natural ventilation. The effectiveness of natural ventilation varies with atmospheric conditions and building design. In a challenge test of a legacy design ward, this study showed that portable air filtration significantly increased the clearance of pollutant aerosols of respirable size compared with natural ventilation, and reduced spatial variation in particle persistence. A combination of natural ventilation and portable air filtration is significantly more effective for particle clearance than either intervention alone.

Abstract
To improve 'bench-to-bedside' translation, it is integral that knowledge flows bidirectionally-from animal models to humans, and vice versa. This requires common analytical frameworks, as well as open software and data sharing practices. We share a new pipeline (and test dataset) for the preprocessing of wide-field optical fluorescence imaging data-an emerging mode applicable in animal models-as well as results from a functional connectivity and graph theory analysis inspired by recent work in the human neuroimaging field. The approach is demonstrated using a dataset comprised of two test-cases: (1) data from animals imaged during awake and anesthetized conditions with excitatory neurons labeled, and (2) data from awake animals with different genetically encoded fluorescent labels that target either excitatory neurons or inhibitory interneuron subtypes. Both seed-based connectivity and graph theory measures (global efficiency, transitivity, modularity, and characteristic path-length) are shown to be useful in quantifying differences between wakefulness states and cell populations. Wakefulness state and cell type show widespread effects on canonical network connectivity with variable frequency band dependence. Differences between excitatory neurons and inhibitory interneurons are observed, with somatostatin expressing inhibitory interneurons emerging as notably dissimilar from parvalbumin and vasoactive polypeptide expressing cells. In sum, we demonstrate that our pipeline can be used to examine brain state and cell-type differences in mesoscale imaging data, aiding translational neuroscience efforts. In line with open science practices, we freely release the pipeline and data to encourage other efforts in the community.

Abstract
AIM To investigate the diagnostic accuracy of ultrasound microcalcifications for the detection of malignancy in thyroid nodules and determine the validity of the concept that ultrasound microcalcification reflects the presence of psammoma body calcification in thyroid nodules. MATERIALS AND METHODS The laboratory information system at University Hospital Galway, a tertiary referral hospital, was used to compile a list of patients who underwent thyroid lobectomy or complete thyroidectomy over a continuous 12-month period with both preoperative ultrasound and postoperative histology available (n=106) from January to December 2019. The haematoxylin and eosin-stained histology slides of each case were sourced and reviewed under light microscopy by a histopathologist to determine the presence of psammoma body calcification within both benign and malignant thyroid nodules. Two radiologists reviewed preoperative thyroid ultrasound images of each case independently and blindly, and reported on the presence of ultrasonographic microcalcification. RESULTS There was a strong and significant relationship between the presence of preoperative ultrasound microcalcification and thyroid malignancy (p<0.001). Ultrasound microcalcification had a high specificity (93%) and positive predictive value (75%) for thyroid malignancy, with a diagnostic accuracy of 76%. Negative predictive value was high at 76.7%, while sensitivity was low at 42.8%. There was a strong and significant association between the presence of preoperative ultrasound microcalcification in thyroid nodules and the presence of pathological psammoma bodies on histology (p<0.001). DISCUSSION Ultrasound microcalcification has a strong and significant association with malignancy in thyroid nodules. This study supported the theory that ultrasound microcalcification occurs secondary to the presence of psammoma bodies within thyroid nodules.

Abstract
INTRODUCTION Higher comorbidity and older age have been reported as correlates of poor outcomes in COVID-19 patients worldwide; however, US data are scarce. We evaluated mortality predictors of COVID-19 in a large cohort of hospitalized patients in the United States. DESIGN Retrospective, multicenter cohort of inpatients diagnosed with COVID-19 by RT-PCR from 1 March to 17 April 2020 was performed, and outcome data evaluated from 1 March to 17 April 2020. Measures included demographics, comorbidities, clinical presentation, laboratory values and imaging on admission. Primary outcome was mortality. Secondary outcomes included length of stay, time to death and development of acute kidney injury in the first 48-h. RESULTS The 1305 patients were hospitalized during the evaluation period. Mean age was 61.0 ± 16.3, 53.8% were male and 66.1% African American. Mean BMI was 33.2 ± 8.8 kg m-2 . Median Charlson Comorbidity Index (CCI) was 2 (1-4), and 72.6% of patients had at least one comorbidity, with hypertension (56.2%) and diabetes mellitus (30.1%) being the most prevalent. ACE-I/ARB use and NSAIDs use were widely prevalent (43.3% and 35.7%, respectively). Mortality occurred in 200 (15.3%) of patients with median time of 10 (6-14) days. Age > 60 (aOR: 1.93, 95% CI: 1.26-2.94) and CCI > 3 (aOR: 2.71, 95% CI: 1.85-3.97) were independently associated with mortality by multivariate analyses. NSAIDs and ACE-I/ARB use had no significant effects on renal failure in the first 48 h. CONCLUSION Advanced age and an increasing number of comorbidities are independent predictors of in-hospital mortality for COVID-19 patients. NSAIDs and ACE-I/ARB use prior to admission is not associated with renal failure or increased mortality.

Abstract
Abstract
Invasive lobular carcinoma (ILC) is a subtype of breast cancer comprising 10% of breast tumours. ILC is characterised by a loss of E-cadherin, and is generally estrogen receptor (ER) positive. The majority of ILC breast cancers are treated with endocrine therapy, although approximately one in three women are de novo resistant to therapy. To identify novel therapeutic targets for the treatment of ILC, we carried out RNA sequencing on 61 primary ILC samples. We found that high expression of the epigenetic reader, bromodomain protein 3 (BRD3) was associated with poor recurrence free survival. We also validated this finding in a separate cohort of 99 ILC patient samples using the METABRIC cohort. Next, we assessed ILC cell lines for sensitivity to JQ1, an inhibitor of BET family proteins. We found that JQ1 inhibited cell growth in all the cell lines tested. Interesting, two of the ILC cell lines were sensitive to JQ1-induced apoptosis, whereas two of the cell lines were inherently resistant to JQ1-induced apoptosis. Using dynamic BH3 profiling we showed that the JQ1 resistant cell lines were dependent on anti-apoptotic protein BCL-XL following JQ1 treatment. Interestingly, we show both in 2D and 3D cultures that JQ1 is synergistic when combined with the BH3 mimetic, ABT-263. Highlighting that combination treatment with JQ1 and ABT-263 may be a novel potential therapeutic option for ILC.
To unveil the mechanism underlying resistance to JQ1-induced apoptosis, we performed paired-end RNA sequencing and compared differentially expressed genes in JQ1 sensitive and JQ1 resistant ILC cell lines. DAVID gene ontology analysis identified 6 pathways differentially upregulated in the JQ1 resistant ILC cell line including MAPK, Wnt, and insulin resistance signaling. Interestingly, we found that ILC cell lines, which were resistant to BET inhibition with JQ1, demonstrated high levels of FGFR1-4 both at the mRNA level and the protein level. Combination treatment with JQ1 and the FGFR1 inhibitor PD173074 or following knockdown of FGFR with siRNA, resulted in increased cell death in JQ1 resistant cells. Currently, we are assessing how FGFR signaling enables survival of ILC cells following JQ1 treatment and determining the exact function of BRD3 in ILC. In conclusion, we have identified a novel therapeutic target, BRD3, which may be inhibited using JQ1 in combination with BH3 mimetic ABT-263 or FGFR1 inhibitor for a more effective treatment strategy for ILC.

Abstract
BACKGROUND Detailed analysis of the immunological pathways leading to robust vaccine responses has become possible with the application of systems biology, including transcriptomic analysis. Venous blood is usually obtained for such studies but others have obtained capillary blood (e.g. finger-prick). Capillary samples are practically advantageous, especially in children. METHODS The aim of this study was to compare gene expression profiles in venous and capillary blood before, 12h and 24h after vaccination with 23-valent pneumococcal polysaccharide or trivalent inactivated seasonal influenza vaccines. RESULTS Gene expression at baseline was markedly different between venous and capillary samples, with 4940 genes differentially expressed, and followed a different pattern of changes after vaccination. At baseline, multiple pathways were upregulated in venous compared to capillary blood, including transforming growth factor-beta receptor signalling and toll-like receptor cascades. After vaccination with the influenza vaccine, there was enrichment for T and NK cell related signatures in capillary blood, and monocyte signatures in venous blood. By contrast, after vaccination with the pneumococcal vaccination, there was enrichment of dendritic cells, monocytes and interferon related signatures in capillary blood, whilst at 24h there was enrichment for T and NK cell related signatures in venous blood. CONCLUSIONS These data show differences between venous and capillary gene expression both at baseline, and post vaccination, which may impact on the conclusions regarding immunological mechanisms drawn from studies using these different sampling methodologies.

Abstract
Abstract
BACKGROUND: Fortified cow’s milk is the main dietary source of vitamin D and an important source of dietary fat for North American children. Current guidelines recommend reduced milk fat consumption to reduce childhood obesity, yet the relationship between lower milk fat, vitamin D stores and adiposity is unclear.
OBJECTIVES: The objective of this study was to determine the association between percent fat content of milk and both zBMI and 25-hydroxyvi-tamin D; secondly, to explore if volume of milk consumed modified this relationship.
DESIGN/METHODS: A cross-sectional study of healthy urban children 12-72 months of age was conducted. Bivariate multiple linear regression was used to test the association between percent milk fat content and child 25-hydroxyvitamin D and zBMI concurrently. The interaction between volume of milk consumed and percent milk fat content was examined to explore how milk volume might modify these relationships.
RESULTS: 2745 children were included in the analysis. Percent fat content of milk was positively associated with 25-hydroxyvitamin D (p=0.006), and negatively associated with zBMI (p<0.0001). Children who drank homogenized milk (3.25% fat) had 6.6 nmol/L (95% CI 5.49 to 7.71) higher median 25(OH)D concentration and 0.72 lower (95% CI 0.68 to 0.76) zBMI score than children who drank skim milk (0.1% fat). Volume of milk consumed potentiated the effect of percent fat content of milk on 25-hydroxyvitamin D (p=0.003) but not on zBMI (p=0.77). Children who drank 1 cup of homogenized milk each day had a similar 25-hydroxyvita-min D as children who drank 2.85 cups (95% CI 2.71 to 2.99) of skim milk, but had zBMI score 0.78 (95% CI 0.63, 0.93) units lower.
CONCLUSION: Homogenized milk may be more appropriate than reduced fat milk in maximizing serum 25-hydroxyvitamin D and minimizing adiposity in early childhood. Current guidelines for reduced milk fat consumption in childhood may require further study to achieve desired outcomes.

Abstract
Traditionally ascending aortic lesions have been repaired in open fashion: stenotomy, cardiopulmonary bypass, with or without deep hypothermic circulatory arrest. However, a subsegment of patients are deemed too high risk for open intervention. In the advent of endovascular advancement, this subset of patients may be treated with the use of stents (physician made, off-label use), branched stents, through a variety of methods and approaches. Although there are currently no large randomized, prospective studies, success has been seen in smaller case series. This review article addresses the identification of anatomy amenable to endovascular repair for management of type A aortic dissection, pseudoaneurysm, and zone 0 lesions. Different approaches to repair, including transapical, transeptal, femoral, common carotid, and axillary graft insertion are also examined. For endovascular treatment of ascending aortic lesions to grow as a field, devices made specifically for the ascending aorta need to be designed and larger trials are necessary to evaluate the rates of complications, morbidity, and mortality, and graft patency.

To explore the possibility of controlling cell interaction with biomaterials, tricalcium phosphate scaffolds were modified using the enzyme tissue transglutaminase (tTgase) in conjunction with fibronectin. Previous reports in the literature have highlighted a number of favourable responses that this protein-enzyme complex can stimulate, including enhancing both cell adhesion, and mineralisation. Fibronectin and tTgase alone were used as controls, and a series of different concentrations of tTgase and fibronectin in combination were assessed. Cell metabolic activity, alkaline phosphatase production, and collagen content were all measured in cultures up to 28 days. Using tetracycline labelling, calcium containing multilayered regions were imaged and quantified. Addition of 6 microg fibronectin resulted in increased alkaline phosphatase activity in all combinations, while increased transglutaminase resulted in more collagen in the cell lysates. Samples treated with fibronectin produced many small mineralised areas, those with 6 microg fibronectin and transglutaminase produced numerous large mineralised areas. The mixture of fibronectin and transglutaminase may prove to be a useful treatment for producing increased osteoblast differentiation on scaffolds.

Abstract
(3-Tert-butyl-7-(5-methylisoxazol-3-yl)-2-(1-methyl-1H-1,2,4-triazol-5-ylmethoxy)pyrazolo[1,5-d] [1,2,4]triazine was recently identified as a functionally selective, inverse agonist at the benzodiazepine site of GABA(A) alpha5-containing receptors, which enhances performance in animal models of cognition. The routes of metabolism of this compound in rat, dog, rhesus monkey and human in vitro systems, and in vivo in rat, dog and rhesus monkey have been characterized. The current study demonstrates that both a cytosolic oxidative reaction and cytochrome P450 play important roles in the metabolism of the compound. Chemical inhibition studies showed the oxidation in human cytosol to be catalysed predominantly by aldehyde oxidase rather than the related enzyme, xanthine oxidase. The aldehyde oxidase-mediated metabolites were present in vitro and in vivo in both rat and rhesus monkey, and also in vitro in man. They were absent both in vitro and in vivo in dog.
