Abstract: The CERN Neutron Time-Of-Flight (n-TOF) facility is well suited to measure small neutron-induced fission cross sections, as those of subactinides. The cross section ratios of {sup nat}Pb and {sup 209}Bi relative to {sup 235}U and {sup 238}U were measured using PPAC detectors. The fragment coincidence method allows to unambiguously identify the fission events. The present experiment provides the first results for neutron-induced fission up to 1 GeV for {sup nat}Pb and {sup 209}Bi. A good agreement with previous experimental data below 200 MeV is shown. The comparison with proton-induced fission indicates that the limiting regime where neutron-induced and proton-induced fission reach equal cross section is close to 1 GeV.

Abstract: The neutron-induced fission cross section of 245Cm was measured at n-TOF in a wide energy range and with high resolution. The energy dependence, measured in a single measurement from 30 meV to 1 MeV neutron energy, has been determined with 5% accuracy relative to the 235U(n,f) cross section. In order to reduce the uncertainty on the absolute value, the data have been normalized at thermal energy to recent measurements performed at ILL and BR1. In the energy range of overlap, the results are in fair agreement with some previous measurements and confirm, on average, the evaluated cross section in the ENDF/B-VII.0 database, although sizable differences are observed for some important resonances below 20 eV. A similar behavior is observed relative to JENDL/AC-2008, a reactor-oriented database for actinides. The new results contribute to the overall improvement of the databases needed for the design of advanced reactor systems and may lead to refinements of fission models for the actinides.

Abstract: The neutron capture cross section of 237Np was measured between 0.7 and 500 eV at the CERN n-TOF facility using the 4π BaF2 Total Absorption Calorimeter. The experimental capture yield was extracted minimizing all the systematic uncertainties and was analyzed together with the most reliable transmission data available using the sammy code. The result is a complete set of individual as well as average resonance parameters [D0=0.56(2) eV, Γγ=40.9(18) meV, 104S0=0.98(6), R ′=9.8(6) fm]. The capture cross section obtained in this work is in overall agreement with the evaluations and the data of Weston and Todd, thus showing sizable differences with respect to previous data from Scherbakov and large discrepancies with data Kobayashi. The results indicate that a new evaluation combining the present capture data with reliable transmission data would allow reaching an accuracy better than 4%, in line with the uncertainty requirements of the nuclear data community for the design and operation of current and future nuclear devices.

Abstract: The successful development of advanced nuclear systems for sustainable energy production and nuclear waste management depends on high quality nuclear data libraries. Recent sensitivity stud- ies and reports [1-3] have identi ed the need for substantially improving the accuracy of neutron cross-section data for minor actinides. The n TOF collaboration has initiated an ambitious exper- imental program for the measurement of neutron capture cross sections of minor actinides. Two experimental setups have been constructed for this purpose: a Total Absorption Calorimeter (TAC) [4] for measuring neutron capture cross-sections of low-mass and/or radioactive samples and a set of two low neutron sensitivity C6D6 detectors for the less radioactive materials.

Abstract: The decay from excited levels in medium and heavy nuclei can be described in a statistical approach by means of Photon Strength Functions and Level Density distributions. The study of electromagnetic cascades following neutron capture based on the use of high e ciency detectors has been shown to be well suited for probing the properties of the Photon Strength Function of heavy (high level density) and/or radioactive (high background) nuclei. In this work we have investigated for the rst time the validity of the recommended PSF of actinides, in particular 235U, 238Np and 241Pu. Our study includes the search for resonance structures in the PSF below Sn and draws conclusions regarding their existence and their characteristics in terms of energy, width and electromagnetic nature.

Abstract: The neutron-induced fission cross-section of 241Am has been measured relative to the standard fission cross-section of 235U between 0.5 and 20MeV. The experiment was performed at the CERN n_TOF facility. Fission fragments were detected by a fast ionization chamber by discriminating against the α- particles from the high radioactivity of the samples. The high instantaneous neutron flux and the low background of the n_TOF facility enabled us to obtain uncertainties of ≈ 5%. With the present results it was possible to resolve discrepancies between previous data sets and to confirm current evaluations, thus providing important information for design studies of future reactors with improved fuel burn-up. © The Author(s) 2013.

Abstract: See paper for full list of authors.; The ratio of the neutron-induced fission cross-sections of 243Am and 235U was measured in the energy range from 0.5 to 20 MeV with uncertainties of ≈ 4%. The experiment was performed at the CERN n_TOF facility using a fast ionization chamber. With the good counting statistics that could be achieved thanks to the high instantaneous flux and the low backgrounds, the present results are useful for resolving discrepancies in previous data sets and are important for future reactors with improved fuel burn-up.

359. Differences between Lower Extremity Arterial Occlusion vs. Stenosis and Predictors of Successful Endovascular Interventions.

Author: Kokkinidis DG, Schizas D, Pargaonkar S, Karamanis D, Mylonas KS, Hasemaki N, Palaiodimos L, Varrias D, Tzavellas G, Siasos G, Klonaris C, Kharawala A, Chlorogiannis DD, Georgopoulos S, and Bakoyiannis C
Subjects: Humans, Constriction, Pathologic surgery, Treatment Outcome, Lower Extremity blood supply, Aspirin therapeutic use, Chronic Disease, Retrospective Studies, Risk Factors, Peripheral Arterial Disease surgery, Arterial Occlusive Diseases surgery, Endovascular Procedures, Neoplasms
Abstract: Background and Objectives: In patients with peripheral artery disease, there is insufficient understanding of characteristics that predict successful revascularization of the lower extremity (LE) chronic total occlusions (CTOs) and baseline differences in demographic, clinical, and angiographic characteristics in patients with LE CTO vs. non-CTO. We aim to explore these differences and predictors of successful revascularization among CTO patients. Materials and Methods: Two vascular centers enrolled LE-CTO patients who underwent endovascular revascularization. Data on demographics, clinical, angiographic, and interventional characteristics were collected. LE non-CTO arterial stenosis patients were compared. A total of 256 patients with LE revascularization procedures were studied; among them, 120 had CTOs and 136 had LE stenosis but no CTOs. Results: Aspirin use (Odds ratio, OR: 3.43; CI 1.32-8.88; p = 0.011) was a positive predictor whereas a history of malignancy (OR: 0.27; CI 0.09-0.80; p = 0.018) was a negative predictor of successful crossing in the CTO group. The CTO group had a higher history of myocardial infarction (29.2 vs. 18.3%, p = 0.05), end-stage renal disease (19.2 vs. 9.6%, p = 0.03), and chronic limb-threatening ischemia as the reason for revascularization (64.2 vs. 22.8%, p < 0.001). They were more likely to have advanced TransAtlantic Inter-Society Consensus (TASC) stages, multi-vessel revascularization procedures, longer lesions, and urgent treatment. Conclusions: The use of aspirin is a positive predictor whereas a history of malignancy is a negative predictor for successful crossing in CTO lesions. Additionally, LE-CTO patients have a higher incidence of comorbidities, which is expected given their higher disease burden. Successful endovascular re-vascularization can be associated with baseline clinical variables.

361. Assessment of the Utilization of Validated Diagnostic Predictive Tools and D-Dimer in the Evaluation of Pulmonary Embolism: A Single-Center Retrospective Cohort Study from a Public Hospital in New York City.

Abstract: Introduction: A significant increase in the use of computed tomography with pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism (PE) has been observed in the past twenty years. We aimed to investigate whether the validated diagnostic predictive tools and D-dimers were adequately utilized in a large public hospital in New York City., Methods: We conducted a retrospective review of patients who underwent CTPA for the specific indication of ruling out PE over a period of one year. Two independent reviewers, blinded to each other and to the CTPA and D-dimer results, estimated the clinical probability (CP) of PE using Well's score, the YEARS algorithm, and the revised Geneva score. Patients were classified based on the presence or absence of PE in the CTPA., Results: A total of 917 patients were included in the analysis (median age: 57 years, female: 59%). The clinical probability of PE was considered low by both independent reviewers in 563 (61.4%), 487 (55%), and 184 (20.1%) patients based on Well's score, the YEARS algorithm, and the revised Geneva score, respectively. D-dimer testing was conducted in less than half of the patients who were deemed to have low CP for PE by both independent reviewers. Using a D-dimer cut-off of <500 ng/mL or the age-adjusted cut-off in patients with a low CP of PE would have missed only a small number of mainly subsegmental PE. All three tools, when combined with D-dimer < 500 ng/mL or 95%., Conclusion: All three validated diagnostic predictive tools were found to have significant diagnostic value in ruling out PE when combined with a D-dimer cut-off of <500 ng/mL or the age-adjusted cut-off. Excessive use of CTPA was likely secondary to suboptimal use of diagnostic predictive tools.

Abstract: In this study, we aimed to illustrate the trajectory of humoral and cellular immunity nine months after primary vaccination with the BNT162b2 mRNA vaccine among 189 healthcare workers (HCWs). Additionally, we endeavored to identify correlations between immunity parameters and a number of common variables and comorbidities. A total of 189 healthcare workers (HCWs), vaccinated against COVID-19, were finally included in the study. All of the subjects had received two doses of the BNT162b2 vaccine; had undergone antibody tests one, four and nine months post-vaccination; and had completed a medical questionnaire. Further samples taken at nine months were tested for cellular immunity. No participants had evidence of COVID-19 infection pre- or post-vaccination. An anti-S1 receptor binding domain (RBD) antibody assay was used to assess humoral response, and cellular immunity was estimated with an INF-γ release assay (IGRA). Statistical analysis was performed using STATA. We report a statistically significant antibody drop over time. Being above the age of 40 or a smoker reduces the rise of antibodies by 37% and 28%, respectively. More than half of the participants did not demonstrate T-cell activation at nine months. Female gender and antibody levels at four months predispose detection of cellular immunity at nine months post-immunization. This study furthers the qualitative, quantitative, and temporal understanding of the immune response to the BNT162b2 mRNA vaccine and the effect of correlated factors.

Abstract: Rheumatoid arthritis (RA) and affective disorders (anxiety/depression) constitute important pathologies in the elderly population, and their coexistence creates synergistically increased problems in functional ability and quality of life of the patients., Purpose: Evaluation of anxiety, distress, and depression in elderly (≥65 years old) patients with RA., Patients – Methods: 114 patients from the cities of Patras, Arta and Ioannina (all located in Western Greece) were included. Demographics and medical information regarding RA were recorded, including disease duration, medication, previous treatments, disease activity measures, comorbidities etc. Patients answered the State-Trait Anxiety Inventory (STAI), General Health Questionnaire-28 (GHQ28) and Health Assessment Questionnaire -Disability Index (HAQ-DI) questionnaires, for evaluation of anxiety, general health and functional ability, respectively. Statistical analysis was made by using STATA., Results: 88 women (78.07%) and 25 men (21.93%) with median age 70 years and median disease duration 10 years were studied. Female patients, with longer disease duration and higher disease activity, had statistically significant higher levels of anxiety, worse general health and decreased functional ability. A strongly significant association was found between the levels of anxiety and distress, with disease activity and functional inability., Conclusions: Levels of anxiety and distress are strongly associated with disease activity and functional inability in elderly patients with RA. Women with longer disease have higher levels of anxiety and distress. Controlling disease activity is of upmost importance for improvement of anxiety and distress and functional ability. Larger studies are needed for evaluation of anxiety and distress in elderly patients with RA., Competing Interests: The authors declare no conflict of interest., (© 2022 The Mediterranean Journal of Rheumatology (MJR).)

Subjects: Female, Humans, Middle Aged, Incidence, Randomized Controlled Trials as Topic, COVID-19 epidemiology, Stroke epidemiology
Abstract: Background: COVID-19 has been frequently associated with an increased risk of thrombotic complications. There have also been reports of an increased likelihood of stroke, although its true incidence in patients with COVID-19 is currently unknown., Methods: Electronic databases PubMed and Scopus were searched from inception up to July 30, 2021 to identify randomized controlled studies in patients with confirmed COVID-19 undergoing one or more interventions. Studies were screened for eligibility using a predefined inclusion criterion and selected using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A random-effects model meta-analysis was conducted, and heterogeneity was assessed using I-squared test., Results: Out of 3960 potentially eligible articles, 77 randomized studies (38 732 patients) were included. Mean age of the study population was 55±9.3 years. Females constituted 38% of the study population and mean duration of follow-up after study enrollment was 23±12.9 days. Cumulative incidence of stroke in the overall study population was 0.001 (95% CI, 0.001-0.002) with a total of 65 events in 38 732 patients, corresponding to an absolute incidence of 0.168%. Incidence of stroke in the inpatient population was 0.001 (95% CI, 0.001-0.002; 65 events in 37 069 patients), corresponding to an absolute incidence of 0.175%. No strokes were observed in the outpatient setting., Conclusions: The overall incidence of stroke in patients with COVID-19 appears to be lower than that reported in previous observational reports.

Abstract: Objective: There is paucity of data on the epidemiological, microbiological, and clinical characteristics of patients admitted with infective endocarditis (IE) in the Bronx, New York., Patient and Methods: We conducted a retrospective study at Jacobi Medical Center, a tertiary care hospital in the Bronx. All adult patients who were hospitalized with a primary diagnosis of new-onset IE between January 1st, 2010 and September 30th, 2020 were included. The primary outcome was in-hospital mortality. A logistic regression model was used to identify baseline variables associated with in-hospital mortality., Results: 182 patients were included in this analysis (female sex: 38.5%, median age: 54 years). 46 patients (25.3%) reported intravenous drug use. 153 patients (84.1%) had positive blood cultures. Staphylococcus aureus (S. aureus) was the most common isolated pathogen (45.1% of monomicrobial IE). Nearly half of the cases secondary to S. aureus were methicillin resistant Staphylococcus aureus (MRSA) (34/69). 164 patients (90.1%) were diagnosed with native valve IE. The mitral valve was involved in 32.4% of patients followed by the aortic valve (19.8%). The in-hospital mortality was 18.1%. The mortality was higher in the cohort 2010-2015 compared to the cohort 2016-2020 (22.1% vs 14.6%). Increasing age, MRSA IE, and active malignancy were the only variables found to have significant association with in-hospital death., Conclusion: S. aureus was the most common causative agent and MRSA accounted for about half of the S. aureus IE cases. The incidence of IE in patients with intravenous drug use increased over time, while the median age decreased. The in-hospital death rate was higher in 2010-2015 compared to 2016-2020., (© 2022.

Abstract: The use of drug-coated devices (DCD) in peripheral arterial disease (PAD) intervention continues to remain controversial after a recent meta-analysis raised concerns of higher late mortality outcome with the use of these devices. Given this, there is need for more data with regards to the late mortality outcome with DCD use. We sought to assess the 2-year mortality outcome in patients with PAD treated with DCD in an inner-city public hospital that mainly serves patients of lower socio-economic status., Methods: This was an observational study of consecutive patients with femoropopliteal arterial disease who had revascularization procedures from 2014 to 2018 at Jacobi Medical Center and were followed for 2 years. Patients were classified into DCD and non-drug-coated (nDCD) groups based on the device used at the index procedure. The primary endpoint was 2-year mortality. Propensity cohort matching was applied. A multivariate Cox regression model was used to identify baseline variables associated with 2-year mortality., Results: 152 patients were included in this analysis (DCD group = 83, nDCD group =69). No significant difference in mortality between the two groups was identified at 2 years after propensity score matching with replacement (DCD: HR 0.72; 95% CI 0.30-1.71; p = 0.457). Patients that had revascularization because of intermittent claudication had lower mortality at 2 years compared to patients with critical limb ischemia as procedure indication (HR 0.18; 95% CI 0.04-0.82; p = 0.026)., Conclusions: This propensity score matched study revealed no difference in 2-year mortality between patients treated with DCD compared to patients treated with nDCD., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Inc.

367. Remdesivir in the Treatment of COVID-19: A Propensity Score-Matched Analysis from a Public Hospital in New York City Assessing Renal and Hepatic Safety.

Author: Lim H, Palaiodimos L, Berto CG, Tedunjaiye O, Malik P, Nagraj S, Choi H, Hti Lar Seng NS, Kladas M, Kharawala A, Karamanis D, Varma N, and Anjali A
Abstract: While the relative efficacy of remdesivir as a therapeutic agent in selected patients with COVID-19 has been established, safety concerns have been raised regarding potential nephrotoxicity and hepatotoxicity. Our main objective was to investigate the kidney- and liver-related safety outcomes in patients with COVID-19 treated with remdesivir in a public hospital in New York. A propensity score-matched retrospective study was conducted in hospitalized patients with COVID-19 from 1 June 2020 to 10 March 2021. A total of 927 patients were included in this study (remdesivir: 427, non-remdesivir: 500; women: 51.8%; median age 61 years; median BMI: 28.5 kg/m2). Matching without replacement yielded a cohort of 248 patients (124 in each group). In the matched cohort, the remdesivir group had a significantly lower rate of acute kidney injury (AKI) (12.1% vs. 21.8%, p = 0.042), a lower rate of acute liver injury (ALI) on the verge of statistical significance (7.3% vs. 14.5%, p = 0.067), and non-significantly lower death rate (13.7% vs. 16.1%, p = 0.593) compared to the non-remdesivir group. Multivariable analyses revealed that patients treated with remdesivir were found to be associated with a significantly lower likelihood for AKI (OR: 0.40; 95% CI: 0.24−0.67, p < 0.001), no association was found for ALI (OR: 0.68; 95% CI: 0.35−1.30, p = 0.241), while a trend towards an association of patients treated with remdesivir with a lower likelihood for in-hospital death was observed (OR: 0.57; 95% CI: 0.32−1.01, p = 0.053). In conclusion, no safety concerns with regards to renal and liver outcomes were raised in patients with COVID-19 treated with remdesivir. Instead, there were signals of possible nephroprotection and improved in-hospital mortality.

Abstract: As is known, HOXB9 is an important factor affecting disease progression and overall survival (OS) in cancer. However, its role in colorectal cancer (CRC) remains unclear. We aimed to explore the role of HOXB9 in CRC progression and its association with OS in colorectal liver metastases (CRLM). We analysed differential HOXB9 expression in CRC using the Tissue Cancer Genome Atlas database (TCGA). We modulated HOXB9 expression in vitro to assess its impact on cell proliferation and epithelial-mesenchymal transition (EMT). Lastly, we explored the association of HOXB9 protein expression with OS, using an institutional patient cohort ( n = 110) who underwent liver resection for CRLM. Furthermore, HOXB9 was upregulated in TCGA-CRC ( n = 644) vs. normal tissue ( n = 51) and its expression levels were elevated in KRAS mutations ( p < 0.0001). In vitro, HOXB9 overexpression increased cell proliferation ( p < 0.001) and upregulated the mRNA expression of EMT markers ( VIM , CDH2 , ZEB1 , ZEB2 , SNAI1 and SNAI2 ) while downregulated CDH1 , ( p < 0.05 for all comparisons). Conversely, HOXB9 silencing disrupted cell growth ( p < 0.0001). High HOXB9 expression (HR = 3.82, 95% CI: 1.59-9.2, p = 0.003) was independently associated with worse OS in CRLM-HOXB9-expressing patients after liver resection. In conclusion, HOXB9 may be associated with worse OS in CRLM and may promote CRC progression, whereas HOXB9 silencing may inhibit CRC growth.

Abstract: Severe obesity increases the risk for negative outcomes in patients with coronavirus disease 2019 (COVID-19). Our objectives were to investigate the effect of BMI on in-hospital outcomes in our New York City Health and Hospitals' ethnically diverse population, further explore this effect by age, sex, race/ethnicity, and timing of admission, and, given the relationship between COVID-19 and hyperinflammation, assess the concentrations of markers of systemic inflammation in different BMI groups. A retrospective study was conducted in hospitalized patients with COVID-19 in the public health care system of New York City from 1 March 2020 to 31 October 2020. A total of 8833 patients were included in this analysis (women: 3593, median age: 62 years). The median body mass index (BMI) was 27.9 kg/m 2 . Both overweight and obesity were independently associated with in-hospital death. The association of overweight and obesity with death appeared to be stronger in men, younger patients, and individuals of Hispanic ethnicity. We did not observe higher concentrations of inflammatory markers in patients with obesity as compared to those without obesity. In conclusion, overweight and obesity were independently associated with in-hospital death. Obesity was not associated with higher concentrations of inflammatory markers.

Abstract: Objective: Previous studies have unveiled a relationship between the severity of coronavirus disease 2019 (COVID-19) pneumonia and obesity. The aims of this multicenter retrospective cohort study were to disentangle the association of BMI and associated metabolic risk factors (diabetes, hypertension, hyperlipidemia, and current smoking status) in critically ill patients with COVID-19., Methods: Patients admitted to intensive care units for COVID-19 in 21 centers (in Europe, Israel, and the United States) were enrolled in this study between February 19, 2020, and May 19, 2020. Primary and secondary outcomes were the need for invasive mechanical ventilation (IMV) and 28-day mortality, respectively., Results: A total of 1,461 patients were enrolled; the median (interquartile range) age was 64 years (40.9-72.0); 73.2% of patients were male; the median BMI was 28.1 kg/m 2 (25.4-32.3); a total of 1,080 patients (73.9%) required IMV; and the 28-day mortality estimate was 36.1% (95% CI: 33.0-39.5). An adjusted mixed logistic regression model showed a significant linear relationship between BMI and IMV: odds ratio = 1.27 (95% CI: 1.12-1.45) per 5 kg/m 2 . An adjusted Cox proportional hazards regression model showed a significant association between BMI and mortality, which was increased only in obesity class III (≥40; hazard ratio = 1.68 [95% CI: 1.06-2.64])., Conclusions: In critically ill COVID-19 patients, a linear association between BMI and the need for IMV, independent of other metabolic risk factors, and a nonlinear association between BMI and mortality risk were observed., (© 2021 The Obesity Society.)

Abstract: It has been demonstrated that obesity is an independent risk factor for worse outcomes in patients with COVID-19. Our objectives were to investigate which classes of obesity are associated with higher in-hospital mortality and to assess the association between obesity and systemic inflammation. This was a retrospective study which included consecutive hospitalized patients with COVID-19 in a tertiary center. Three thousand five hundred thirty patients were included in this analysis (female sex: 1579, median age: 65 years). The median body mass index (BMI) was 28.8 kg/m 2 . In the overall cohort, a J-shaped association between BMI and in-hospital mortality was depicted. In the subgroup of men, BMI 35-39.9 kg/m 2 and BMI ≥40 kg/m 2 were found to have significant association with higher in-hospital mortality, while only BMI ≥40 kg/m 2 was found significant in the subgroup of women. No significant association between BMI and IL-6 was noted. Obesity classes II and III in men and obesity class III in women were independently associated with higher in-hospital mortality in patients with COVID-19. The male population with severe obesity was the one that mainly drove this association. No significant association between BMI and IL-6 was noted., (© 2021.

Abstract: Purpose: Infectious diseases are more frequent and can be associated with worse outcomes in patients with diabetes. The aim of this study was to systematically review and conduct a meta-analysis of the available observational studies reporting the effect of diabetes on mortality among hospitalized patients with COVID-19., Methods: The Medline, Embase, Google Scholar, and medRxiv databases were reviewed for identification of eligible studies. A random effects model meta-analysis was used, and I 2 was utilized to assess the heterogeneity. In-hospital mortality was defined as the endpoint. Sensitivity, subgroup, and meta-regression analyses were performed., Results: A total of 18,506 patients were included in this meta-analysis (3713 diabetics and 14,793 non-diabetics). Patients with diabetes were associated with a higher risk of death compared with patients without diabetes (OR 1.65; 95% CI 1.35-1.96; I 2 77.4%). The heterogeneity was high. A study-level meta-regression analysis was performed for all the important covariates, and no significant interactions were found between the covariates and the outcome of mortality., Conclusion: This meta-analysis shows that that the likelihood of death seems to be higher in diabetic patients hospitalized with COVID-19 compared with non-diabetic patients. Further studies are needed to assess whether this association is independent or not, as well as to investigate the role of adequate glycemic control prior to infection with COVID-19.

373. Assessment of the Association of COPD and Asthma with In-Hospital Mortality in Patients with COVID-19. A Systematic Review, Meta-Analysis, and Meta-Regression Analysis.

Author: Reyes FM, Hache-Marliere M, Karamanis D, Berto CG, Estrada R, Langston M, Ntaios G, Gulani P, Shah CD, and Palaiodimos L
Abstract: Together, chronic obstructive pulmonary disease (COPD) and asthma account for the most common non-infectious respiratory pathologies. Conflicting preliminary studies have shown varied effect for COPD and asthma as prognostic factors for mortality in coronavirus disease 2019 (COVID-19). The aim of this study was to explore the association of COPD and asthma with in-hospital mortality in patients with COVID-19 by systematically reviewing and synthesizing with a meta-analysis the available observational studies. MEDLINE, Scopus, and medRxiv databases were reviewed. A random-effects model meta-analysis was used, and I-square was utilized to assess for heterogeneity. In-hospital mortality was defined as the primary endpoint. Sensitivity and meta-regression analyses were performed. Thirty studies with 21,309 patients were included in this meta-analysis (1465 with COPD and 633 with asthma). Hospitalized COVID-19 patients with COPD had higher risk of death compared to those without COPD (OR: 2.29; 95% CI: 1.79-2.93; I 2 59.6%). No significant difference in in-hospital mortality was seen in patients with and without asthma (OR: 0.87; 95% CI: 0.68-1.10; I 2 0.0%). The likelihood of death was significantly higher in patients with COPD that were hospitalized with COVID-19 compared to patients without COPD. Further studies are needed to assess whether this association is independent or not. No significant difference was demonstrated in COVID-19-related mortality between patients with and without asthma.

Abstract: Objective: To explore the possible associations of serum 25-hydroxyvitamin D [25(OH)D] concentration with coronavirus disease 2019 (COVID-19) in-hospital mortality and need for invasive mechanical ventilation., Patients and Methods: A retrospective, observational, cohort study was conducted at 2 tertiary academic medical centers in Boston and New York. Eligible participants were hospitalized adult patients with laboratory-confirmed COVID-19 between February 1, 2020, and May 15, 2020. Demographic and clinical characteristics, comorbidities, medications, and disease-related outcomes were extracted from electronic medical records., Results: The final analysis included 144 patients with confirmed COVID-19 (median age, 66 years; 64 [44.4%] male). Overall mortality was 18%, whereas patients with 25(OH)D levels of 30 ng/mL (to convert to nmol/L, multiply by 2.496) and higher had lower rates of mortality compared with those with 25(OH)D levels below 30 ng/mL (9.2% vs 25.3%; P=.02). In the adjusted multivariable analyses, 25(OH)D as a continuous variable was independently significantly associated with lower in-hospital mortality (odds ratio, 0.94; 95% CI, 0.90 to 0.98; P=.007) and need for invasive mechanical ventilation (odds ratio, 0.96; 95% CI, 0.93 to 0.99; P=.01). Similar data were obtained when 25(OH)D was studied as a continuous variable after logarithm transformation and as a dichotomous (<30 ng/mL vs ≥30 ng/mL) or ordinal variable (quintiles) in the multivariable analyses., Conclusion: Among patients admitted with laboratory-confirmed COVID-19, 25(OH)D levels were inversely associated with in-hospital mortality and the need for invasive mechanical ventilation. Further observational studies are needed to confirm these findings, and randomized clinical trials must be conducted to assess the role of vitamin D administration in improving the morbidity and mortality of COVID-19., (Copyright © 2021 Mayo Foundation for Medical Education and Research.

Abstract: Background: Surveys report low frequencies of sexual history (SH) obtained in primary care. Sexually transmitted infections incidence can be reduced with timely screening. It is important to determine whether providers obtain thorough SH and to identify needs for improvement., Aim: To evaluate the frequency and depth of SH taking in primary care., Methods: In this cross-sectional cohort study, 1,017 primary care visits were reviewed (1,017 adult patients, female 55.26%). 417 patients were seen by male providers and 600 patients were seen by female providers. Multivariate ordered and logit models were deployed., Main Outcome Measures: The primary outcome measures included SH taking rates and completeness based on the 5 P model as described by the Centers for Disease Control and Prevention., Results: All components of SH were explored in 1.08% of visits. Partial SH was obtained in 33.92% of visits. No SH was taken in the majority of visits (65%). SH was more likely to be taken from female patients than from male patients (P < .001), and was less likely to be obtained from older patients as compared to younger individuals (P < .001). There was no significant difference in SH taking between male and female providers (P = .753). The provider title and the level of training were found to be independent predictors of SH taking (P < .001)., Clinical Implications: The results of this study highlight an unmet need for more comprehensive and consistent SH taking amongst providers, particularly in high-risk settings, so that SH can be used as a valuable tool in preventive care., Strengths & Limitations: To the best of our knowledge, this is the largest study to date examining SH taking in the primary care setting. Limitations include the retrospective study design, lack of generalizability to other hospitals, and inconsistencies in available data., Conclusion: The SH taking rates in primary care clinics are globally low with a variation depending on the provider position or level of training, provider gender, and patient age.

Abstract: Background & Aims: New York is the current epicenter of Coronavirus disease 2019 (COVID-19) pandemic. The underrepresented minorities, where the prevalence of obesity is higher, appear to be affected disproportionately. Our objectives were to assess the characteristics and early outcomes of patients hospitalized with COVID-19 in the Bronx and investigate whether obesity is associated with worse outcomes independently from age, gender and other comorbidities., Methods: This retrospective study included the first 200 patients admitted to a tertiary medical center with COVID-19. The electronic medical records were reviewed at least three weeks after admission. The primary endpoint was in-hospital mortality., Results: 200 patients were included (female sex: 102, African American: 102). The median BMI was 30 kg/m 2 . The median age was 64 years. Hypertension (76%), hyperlipidemia (46.2%), and diabetes (39.5%) were the three most common comorbidities. Fever (86%), cough (76.5%), and dyspnea (68%) were the three most common symptoms. 24% died during hospitalization (BMI < 25 kg/m 2 : 31.6%, BMI 25-34 kg/m 2 : 17.2%, BMI ≥ 35 kg/m 2 : 34.8%, p = 0.03). Increasing age (analyzed in quartiles), male sex, BMI ≥ 35 kg/m 2 (reference: BMI 25-34 kg/m 2 ), heart failure, CAD, and CKD or ESRD were found to have a significant univariate association with mortality. The multivariate analysis demonstrated that BMI ≥ 35 kg/m 2 (reference: BMI 25-34 kg/m 2 , OR: 3.78; 95% CI: 1.45-9.83; p = 0.006), male sex (OR: 2.74; 95% CI: 1.25-5.98; p = 0.011) and increasing age (analyzed in quartiles, OR: 1.73; 95% CI: 1.13-2.63; p = 0.011) were independently associated with higher in-hospital mortality. Similarly, age, male sex, BMI ≥ 35 kg/m 2 and current or prior smoking were significant predictors for increasing oxygenation requirements in the multivariate analysis, while male sex, age and BMI ≥ 35 kg/m 2 were significant predictors in the multivariate analysis for the outcome of intubation., Conclusions: In this cohort of hospitalized patients with COVID-19 in a minority-predominant population, severe obesity, increasing age, and male sex were independently associated with higher in-hospital mortality and in general worse in-hospital outcomes., Competing Interests: Declaration of competing interest All authors declare no conflict of interests., (Copyright © 2020 Elsevier Inc.

Abstract: A method for screening 90Sr in milk samples is proposed. This method is based on a liquid scintillation technique taking advantage of Cherenkov radiation, which is produced in a liquid medium and then detected by the photomultipliers of a Liquid Scintillation Counter (LSC). Twenty millilitres of water and milk samples spiked with various concentrations of 90Sr/90Y in equilibrium were added in plastic vials and then were measured with an LSC (TriCarb 3170 TR/SL). The derived efficiencies were 49% for water samples and 14% for milk samples. The detection limit was 470 mBq L(-1)(90)Sr for water, without any pretreatment. Milk contains potassium, which also produces Cherenkov radiation due to the presence of 40K. For this reason, the interference of 40K in the measurements of 90Sr in milk samples was also investigated. The detection limit for milk was 1.7 Bq L(-1)90Sr.

381. Determination of 226Ra in aqueous solutions via sorption on thin films and alpha-spectrometry.

Author: Karamanis D, Ioannides KG, and Stamoulis KC
Abstract: An improved spectrometric method to determine the 226Ra activity in aqueous solutions is described. The method involves two stages, a preconcentration stage of 226Ra sorption onto a thin manganese layer and a measurement stage using alpha-spectrometry. Manganese oxide thin films were prepared and characterized with X-ray diffraction (XRD) and X-ray fluorescence (XRF) analyses. The thin films were found to follow the XRD patterns and chemical formula of the K-birnessite layered exchanger. The preconcentration of radium was studied relative to the initial radium concentration, pH and salt concentrations. The preconcentration kinetics was studied as a function of manganese surface, solution volume and salt concentration. Extensive Monte Carlo calculations were performed to optimise the detection of alpha-particles. In this way, the thin film preparation procedure as well as the radium sorption and the measurement conditions were optimised and detection limits lower than 0.5 mBq L(-1) were obtained for 2d of procedure completion. The method was validated with IAEA standards and it was applied for the determination of 226Ra in bottled waters and also wastewaters from the major thermoelectric plant in Greece. Moreover, the 226Ra distribution coefficients (K(d)) of two differently prepared powder manganese oxides, a crystalline silicotitanate and an aluminium-pillared montmorillonite were determined by gamma-spectrometry. 226Ra sorption experiments on silicotitanate thin films were performed and improvements in resolution and reduction of exposure time were observed.

Abstract: Soil ingestion as a source of radiocaesium contamination to ruminants was studied by measuring the transfer coefficient to sheep milk. Eight lactating ewes, housed in individual metabolism cages, were used. Fifty grams per day of heavily contaminated sandy topsoil, collected in 1990 from the Chernobyl area, were administered orally to the animals for a period of 1 week. The daily dose intake in 137Cs was 1835 Bq day-1. During this contamination period, daily milk production and excreta output were measured. The ewes were monitored for an additional 7 day decontamination period, while they fed on uncontaminated feed. Transfer coefficients were obtained through a best fit (minimum chi 2) of the data to predictions of a linear compartment model. The values obtained were fm = (2.6 +/- 0.7) x 10(-2) and f mu = (5 +/- 2) x 10(-2) days kg-1 for radiocaesium transport to milk and urine, respectively. These results suggest that soil ingestion can be a major source of radiocontamination for sheep and other free-grazing ruminants. Comparison of our results with soil-to-milk transfer coefficient values derived in two recent independent experiments suggests that there might be a strong dependence of radiocaesium availability on soil composition.
