Abstract

Objectives
To evaluate the analytical and clinical performance of the automated Elecsys anti–severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody (Elecsys Ab) assay on the Roche cobas e602 analyzer. With the ongoing global coronavirus disease 2019 (COVID-19) pandemic, widespread and routine serologic testing of SARS-CoV-2 remains a pressing need. To better understand its epidemiologic spread and to support policies aimed at curtailing further infections, reliable serologic testing is crucial for providing insight into the dynamics of the spread of COVID-19 on a population level.

Methods
The presence of anti–SARS-CoV-2 antibodies in polymerase chain reaction–positive, confirmed COVID-19 patient samples was determined using the Elecsys Ab assay on the Roche cobas e602 analyzer. The precision and cross-reactivity of the Elecsys Ab assay were characterized and its performance was compared against the EuroImmun IgA/IgG antibody (EuroImmun Ab) assay. Calculated sensitivity, specificity, and positive and negative predictive values were assessed.

Results
The Elecsys Ab assay demonstrated good precision, had no cross-reactivity with other viral samples, and showed 100% concordance with the EuroImmun Ab assay. Excellent clinical performance with respect to sensitivity, specificity, and positive and negative predictive values was observed.

Conclusions
The Elecsys Ab assay is a precise and highly reliable automated platform for clinical detection of seropositivity in SARS-CoV-2 infection.

Abstract
Women with a history of breast cancer among family members are at increased risk for breast cancer. However, it is unknown whether a familial breast cancer history (FBCH) also increases individual susceptibility to breast cancer from radiation exposure. In this cohort study, 17,200 female Swedish hemangioma patients with 1,079 breast cancer cases diagnosed between 1958 and 2013, exposed to ionizing radiation in infancy, were linked to their first-degree relatives. The association between FBCH and radiation-induced breast cancer risk was assessed. Further, the relevance for breast cancer radiotherapy and mammography screening was evaluated. On average, the radiation-induced excess relative risk and excess absolute risk of breast cancer at age 50 years were 0.51 Gy−1 (95% confidence interval (CI): 0.33, 0.71) and 10.8 cases/10,000 person-years/Gy (95% CI: 7.0, 14.6), respectively. Radiation risk was higher by a factor of 2.7 (95% CI: 1.0, 4.8; P = 0.05) if 1 first-degree relative was affected by breast cancer. For whole-breast standard radiotherapy at age 40 years with a contralateral breast dose of 0.72 Gy, the 20-year radiation-related excess risk of contralateral breast cancer was estimated to increase from 0.6% for women without FBCH to 1.7% for women with FBCH. In a biennial mammography screening program at ages 40–74 years, radiation risk up to age 80 years would increase from 0.11% for women without FBCH to 0.29% for women with FBCH.

Abstract
Uptake of influenza vaccine among pregnant women remains low. We investigated whether unvaccinated pregnant women were clustered geographically and determined factors associated with failure to vaccinate using spatial and multivariate logistic regression analyses. Pregnant women who were members of Kaiser Permanente Northern California in 2015 or 2016 were included in the study. More than half (53%) of the 77,607 included pregnant women were unvaccinated. Spatial analysis identified 5 clusters with a high prevalence of unvaccinated pregnant women. The proportion of unvaccinated women ranged from 57% to 75% within clusters as compared with 51% outside clusters. In covariate-adjusted analyses, residence in a cluster was associated with a 41% increase in the odds of being unvaccinated (odds ratio (OR) = 1.41, 95% confidence interval (CI): 1.36, 1.46). The odds of being unvaccinated were greater for Black women (OR = 1.58, 95% CI: 1.49, 1.69), Hispanic women (OR = 1.15, 95% CI: 1.05, 1.25), women with subsidized health insurance (OR = 1.18, 95% CI: 1.11, 1.24), women with fewer than 5 prenatal-care visits (OR = 1.85, 95% CI: 1.60, 2.16), and neighborhoods with a high deprivation index (fourth quartile vs. first: OR = 1.14, 95% CI: 1.07, 1.21). In conclusion, unvaccinated pregnant women were clustered geographically and by key sociodemographic factors. These findings suggest that interventions to increase influenza vaccine coverage among pregnant women are needed, particularly in vulnerable populations.

Abstract

BACKGROUND
Our aim was to assess how the population-attributable fraction (PAF) for premature mortality due to cardiovascular disease (CVD) associated with hypertension changes if blood pressure (BP) thresholds for hypertension were lowered from systolic/diastolic BP ≥140/90 mm Hg to ≥130/80 mm Hg, as defined using the 2017 American College of Cardiology/American Heart Association blood pressure guideline.

METHODS
Analyses were conducted using a database of participants who underwent a national health checkup examination started in 2008 in Japan (n = 510,238; mean age, 59.6 ± 8.1 years; 42% men). Each participant was categorized as having normal or elevated BP, or stage 1 or 2 hypertension according to the guideline. Data on premature mortality due to CVD occurring before age 70 years were available through March 2015.

RESULTS
Over a median follow-up of 3.4 years, 739 deaths from CVD occurred. After multivariable adjustment, hazard ratios for premature CVD mortality for elevated BP, stage 1 hypertension, and stage 2 hypertension vs. normal BP were 1.02 (95% confidence interval, 0.72, 1.44), 1.33 (1.02, 1.75), and 2.41 (1.90, 3.05), respectively. The PAF associated with stage 1 and 2 hypertension was 4.4% and 39.4%, respectively.

CONCLUSIONS
In the current nationwide study of Japanese adults, stage 1 and 2 hypertension were associated with an increased risk for premature CVD mortality. The PAF for premature CVD mortality associated with hypertension increased by 4.4% if BP thresholds for hypertension were lowered from systolic/diastolic BP ≥140/90 to ≥130/80 mm Hg.

AbstractAlthough the migration ecology of birds breeding in the Neotropics is still poorly studied relative to that of their counterparts breeding at north-temperate latitudes, studies conducted over the last 2 decades have revealed that migration in the Neotropics is much more common and diverse than previously thought. These studies have identified dozens of species that migrate latitudinally within South America, altitudinally within various mountain ranges, to and between Caribbean islands, and longitudinally across diverse ecosystems such as the Amazon rainforest. Advances in miniaturized tracking technologies, enormous citizen science databases, and powerful analytical approaches provide an unprecedented ability to detect and evaluate temporally and spatially fine-scale patterns, greatly facilitating the study of migratory patterns across tropical regions. We argue that a renewed effort in research on short- and long-distance bird migration within the Neotropics will allow (1) comparative studies that identify the emergent properties of migratory behavior, (2) identification of the convergent or unique mechanistic drivers of migration across diverse ecological settings, (3) formulation of effective conservation and management plans for migratory Neotropical birds, and (4) predictions about how migratory birds will respond to large-scale climatic changes within the Neotropics. Here, we review the current state of knowledge on Neotropical bird migration, with a focus on South America. We specifically examine similarities and differences in the observed migratory patterns of birds that breed in the Nearctic compared to the Neotropics and highlight key future research questions.

AbstractIn Parkinson’s disease, striatal dopamine depletion produces profound alterations in the neural activity of the cortico-basal ganglia motor loop, leading to dysfunctional motor output and parkinsonism. A key regulator of motor output is the balance between excitation and inhibition in the primary motor cortex, which can be assessed in humans with transcranial magnetic stimulation techniques. Despite decades of research, the functional state of cortical inhibition in Parkinson’s disease remains uncertain. Towards resolving this issue, we applied paired-pulse transcranial magnetic stimulation protocols in 166 patients with Parkinson’s disease (57 levodopa-naïve, 50 non-dyskinetic, 59 dyskinetic) and 40 healthy controls (age-matched with the levodopa-naïve group). All patients were studied OFF medication. All analyses were performed with fully automatic procedures to avoid confirmation bias, and we systematically considered and excluded several potential confounding factors such as age, gender, resting motor threshold, EMG background activity and amplitude of the motor evoked potential elicited by the single-pulse test stimuli. Our results show that short-interval intracortical inhibition is decreased in Parkinson’s disease compared to controls. This reduction of intracortical inhibition was obtained with relatively low-intensity conditioning stimuli (80% of the resting motor threshold) and was not associated with any significant increase in short-interval intracortical facilitation or intracortical facilitation with the same low-intensity conditioning stimuli, supporting the involvement of cortical inhibitory circuits. Short-interval intracortical inhibition was similarly reduced in levodopa-naïve, non-dyskinetic and dyskinetic patients. Importantly, intracortical inhibition was reduced compared to control subjects also on the less affected side (n = 145), even in de novo drug-naïve patients in whom the less affected side was minimally symptomatic (lateralized Unified Parkinson’s Disease Rating Scale part III = 0 or 1, n = 23). These results suggest that cortical disinhibition is a very early, possibly prodromal feature of Parkinson’s disease.

Published: July 2020

AbstractBackgroundAmong those with injection drug use-associated infective endocarditis (IDU-IE), against medical advice (AMA) discharge is common and linked to adverse outcomes. Understanding trends, risk factors, and timing is needed to reduce IDU-IE AMA discharges.MethodsWe identified individuals ages 18–64 with International Classification of Diseases, 9thRevision, diagnosis codes for infective endocarditis (IE) in the National Inpatient Sample, a representative sample of United States hospitalizations from January 2010 to September 2015. We plotted unadjusted quarter-year trends for AMA discharges and used multivariable logistic regression to identify factors associated with AMA discharge among IE hospitalizations, comparing IDU-IE with non-IDU-IE.ResultsWe identified 7259 IDU-IE and 23 633 non-IDU-IE hospitalizations. Of these hospitalizations, 14.2% of IDU-IE and 1.9% of non-IDU-IE resulted in AMA discharges. More than 30% of AMA discharges for both groups occurred before hospital day 3. In adjusted models, IDU status (adjusted odds ratio [AOR], 3.92; 95% confidence interval [CI], 3.43–4.48)] was associated with increased odds of AMA discharge. Among IDU-IE, women (AOR, 1.21; 95% CI, 1.04–1.41) and Hispanics (AOR, 1.32; 95% CI, 1.03–1.69) had increased odds of AMA discharge, which differed from non-IDU-IE. Over nearly 6 years, odds of AMA discharge increased 12% per year for IDU-IE (AOR, 1.12; 95% CI, 1.07–1.18) and 6% per year for non-IDU-IE (AOR, 1.06; 95% CI. 1.00–1.13).ConclusionsAMA discharges have risen among individuals with IDU-IE and non-IDE-IE. Among those who inject drugs, AMA discharges were more common and increases sharper. Efforts that address the rising fraction, disparities, and timing of IDU-IE AMA discharges are needed.

Abstract
Elite controllers (ECs) are people living with human immunodeficiency virus (HIV) who spontaneously control viral replication without antiretroviral therapy. We observed that elevated anti-cytomegalovirus (CMV) immunoglobulin G (IgG) levels correlated with annual CD4 T-cell count decay in ECs independently of age, sex, and human leukocyte antigen (HLA) type. Elevated anti-CMV titers may favor disease progression in ECs.
Ordinary Affects and Spectrality in Three Works: Carole Giangrande’sMidsummer, Brenda Missen’sTell Anna She’s Safe, and Andrea Thompson’sOver Our Heads
Authors: Caporale-Bizzini Silvia 
Published: July 2020

AbstractScholars such as Kathleen Stewart and Lauren Berlant have pointed out that neoliberalism stresses the social benefits of individual precariousness for the sake of profit and fosters a sense of personal crisis. In the three contemporary novels I examine, such feelings of crisis permeate the characters’ lives. I build on the concepts of the unexpected and spectrality to analyze Carole Giangrande’s Midsummer (2014), Brenda Missen’s Tell Anna She’s Safe (2011), and Andrea Thompson’s Over Our Heads (2014). These three novels share similar themes: in each, as the result of an unexpected event, specters from the past interact with the present – thereby forcing the central characters to question their beliefs, rethink their ideas about what constitutes a good life, and start a journey of personal discovery.
People are essential to linking biodiversity data

Published: July 2020

Abstract
People are one of the best known and most stable entities in the biodiversity knowledge graph. The wealth of public information associated with people and the ability to identify them uniquely open up the possibility to make more use of these data in biodiversity science. Person data are almost always associated with entities such as specimens, molecular sequences, taxonomic names, observations, images, traits and publications. For example, the digitization and the aggregation of specimen data from museums and herbaria allow us to view a scientist’s specimen collecting in conjunction with the whole corpus of their works. However, the metadata of these entities are also useful in validating data, integrating data across collections and institutional databases and can be the basis of future research into biodiversity and science. In addition, the ability to reliably credit collectors for their work has the potential to change the incentive structure to promote improved curation and maintenance of natural history collections.
Comparative Studies of Reproductive Diapause in North American Populations of ThreeHippodamiaSpecies (Coleoptera: Coccinellidae)
Authors: Obrycki John J 
Published: July 2020

AbstractQuantifying responses of three congeneric species of lady beetles, Hippodamia parenthesis (Say), Hippodamia convergens (Guerin), and Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae), to abiotic factors that influence their seasonal biology provides an understanding of the phenology of these species in North America. The developmental response and the induction and duration of adult hibernal diapause in four North American populations of H. parenthesis, collected between 40° N and 44° N latitude, was determined when beetles were reared at four photoperiods (L:D 16:8, 14:10, 12;12, and 10:14) at 22°C. Preimaginal development of the four H. parenthesis populations reared at the photoperiods was affected by population, photoperiod, and the interaction between population and photoperiod. Fifteen to 19% of H. parenthesis females reared at L:D 16:8 entered diapause, whereas shorter photoperiods (L:D 12:12 and 10:14) induced diapause in all females. Variation in response to L:D 14:10 was observed among the four populations of H. parenthesis, similar to the response observed in H. convergens and H. variegata. In contrast to the response of H. parenthesis females, in which four individuals oviposited at L:D 12:12 or 10:14 within 120 d, the duration of reproductive diapause in H. convergens and H. variegata females at L:D 12:12 and 10:14 showed a prolonged quantitative response to photoperiod. Comparisons of the responses (days to first oviposition) to photoperiod of H. parenthesis and H. variegata from the same collection sites showed significant differences at most photoperiods. Similarly, responses at all photoperiods varied between H. parenthesis and H. convergens from similar latitudes in Iowa.

Published: July 2020

Abstract

Aims
S100B, a well-known damage-associated molecular pattern protein is released acutely by central and peripheral nerves and upon concomitant denervation in pulmonary vein isolation (PVI). We aimed to investigate whether the ablation technique used for PVI impacts S100B release in patients with paroxysmal atrial fibrillation (AF).

Methods and results
The study population consisted of 73 consecutive patients (age: 62.7 ± 10.9 years, 54.8% males) undergoing first-time PVI with either radiofrequency (RF; n = 30) or cryoballoon (CB; n = 43) for paroxysmal AF. S100B determined from venous plasma samples taken immediately before and after PVI increased from 33.5 ± 1.8 to 91.1 ± 5.3 pg/mL (P &lt; 0.0001). S100B release in patients undergoing CB-PVI was 3.9 times higher compared to patients with RF-PVI (ΔS100B: 21.1 ± 2.7 vs. 83.1 ± 5.2  pg/mL, P &lt; 0.0001). During a mean follow-up of 314 ± 186 days, AF recurrences were observed in 18/71 (25.4%) patients (RF-PVI: n = 9/28, CB-PVI: n = 9/43). Univariate Cox regression analysis indicated that an increase in S100B was associated with higher freedom from AF in follow-up (hazard ratio per 10  pg/mL release of S100B: 0.83; 95% confidence interval: 0.72–0.95; P = 0.007).

Conclusion
The ablation technique used for PVI has an impact on the release of S100B, a well-established biomarker for neural damage.

Published: July 2020

AbstractBackgroundPhysicians are often dissatisfied with their own medical care. Self-prescribing is common despite established guidelines that discourage this practice. From a pilot study, we know primary care physicians’ (PCP) preferences, but we lack information regarding other specialties and work places.ObjectivesThe goal of this study was to examine whether physicians are satisfied with their personal primary care and how this could be improved.MethodsWe distributed an electronic survey to all physicians registered with the Israeli Medical Association. The questionnaire examined satisfaction with medical care, preferences for using formal care versus informal care, self-prescribing and barriers to using formal care.ResultsTwo thousand three hundred and five out of 24 360 invited physicians responded. Fifty-six per cent of the respondents were satisfied with their personal primary care. Fifty-two per cent reported initiating self-treatment with a medication during the last year. Five and four per cent initiated treatment with a benzodiazepine and an antidepressant, respectively, during the last year. This was despite the fact that most physicians did not feel competent to treat themselves. Having a personal PCP was correlated with both a desire to use formal care and self-referral to formal care in practice. Regression analysis showed that the highest odds ratio (OR) for experiencing a large gap between desired and actual care were for physicians who had no personal PCP (OR = 1.92).ConclusionsPhysicians frequently engage in self-treatment and in informal medical care. Whether the root cause is the health care system structure that does not meet their needs or the convenience of self-treatment is not known.
