Galaxy and Mass Assembly (GAMA): Variation in galaxy structure across the green valley
Using a sample of 472 local Universe (z \u3c 0.06) galaxies in the stellar mass range 10.25 \u3c logM*/M⊙ \u3c 10.75, we explore the variation in galaxy structure as a function of morphology and galaxy colour. Our sample of galaxies is subdivided into red, green, and blue colour groups and into elliptical and non-elliptical (disk-type) morphologies. Using Kilo- Degree Survey (KiDS) and Visible and Infrared Survey Telescope for Astronomy (VISTA) Kilo-Degree Infrared Galaxy Survey (VIKING) derived postage stamp images, a group of eight volunteers visually classified bars, rings, morphological lenses, tidal streams, shells, and signs of merger activity for all systems. We find a significant surplus of rings (2.3s) and lenses (2.9s) in disk-type galaxies as they transition across the green valley. Combined, this implies a joint ring/lens green valley surplus significance of 3.3s relative to equivalent disk-types within either the blue cloud or the red sequence. We recover a bar fraction of ~44 per cent which remains flat with colour, however, we find that the presence of a bar acts to modulate the incidence of rings and (to a lesser extent) lenses, with rings in barred disk-type galaxies more common by ~20-30 percentage points relative to their unbarred counterparts, regardless of colour. Additionally, green valley disk-type galaxies with a bar exhibit a significant 3.0s surplus of lenses relative to their blue/red analogues. The existence of such structures rules out violent transformative events as the primary end-of-life evolutionary mechanism, with a more passive scenario the favoured candidate for the majority of galaxies rapidly transitioning across the green valley
Estimates of the prevalence of rheumatic diseases in the population of Tecumseh, Michigan, 1959-60
Over 90 per cent of the more than 9000 residents of Tecumseh, Michigan participated in a program of comprehensive health examinations in 1959-1960. Included in the examination were inquiries regarding rheumatic symptoms, physical examination of the spine and peripheral joints, and the latex fixation test for rheumatoid factor and serum uric acid measurement.Joint pain or aching, joint swelling, morning stiffness, and past arthritis or rheumatism were common complaints, occurring in one-eighth to one-third of the population age 6 yr and over. The age-sex specific prevalence rates for each of these historical items rose with increasing age. Male and female rates were quite similar during the first four decades of life, but thereafter female rates were somewhat higher.The prevalence of positive latex fixation tests for rheumatoid factor was essentially the same for male and female subjects, 3.4 per cent for males and 3.35 per cent for females. The rates rose progressively from approximately one per cent in the 6-16 yr age group to almost 14 per cent for males and 9.4 per cent for females in the oldest age groups. The latex fixation test performed poorly as a case detection tool, only one-third of those respondents with positive tests having any other evidence to suggest a diagnosis of rheumatoid arthritis. Relatively high rates of latex positively occurred in individuals with a history of jaundice or infectious hepatitis and in those with evidence of emphysema or right heart failure. None of the respondents with psoriasis or pregnancy at the time of examination had positive latex tests. The prevalence of latex positivity showed a rise with increasing systolic blood pressure in persons over 30 yr of age, but appeared to be unrelated to diastolic blood pressure, serum cholesterol or serum uric acid.Prevalence rates for "definite" rheumatoid arthritis, based on the diagnostic criteria proposed by the American Rheumatism Association, were 0.4 per cent for all subjects age 6 yr and over and 0.5 per cent for all subjects age 16 yr and over. Prevalence rates for "definite" plus "probable" rheumatoid arthritis were 1.3 per cent in the age group 6 yr and over and 1.7 per cent in the age group 16 yr and over. In all diagnostic categories prevalence rates for females exceeded those for males. In the age group 16 yr and over the female to male ratio was 2.3: 1 for "definite" disease and 2.4: 1 for total suspected cases of rheumatoid arthritis. The prevalence rates for rheumatoid arthritis rose with increasing age; rates for "definite" disease rose from 0.44 per cent in the fourth decade to 0.79 per cent in the eighth decade for males and from 1.69 per cent in the fifth decade to 2.47 per cent in the eighth decade for females.The over-all prevalence rates for suspected ankylosing spondylitis, not confirmed by X-ray examination of the spine or sacroiliac joints, were 0.4 per cent for males and 0.05 per cent for females age 6 yr and over.Prevalence rates for osteoarthritis, diagnosed on the basis of physical rather than radiological examination were 2.2 per cent for males and 5.0 per cent for females age 6 yr and over. Rates were highest in the older age groups, being 20.3 per cent for males and 40.8 per cent for females in the age group 60 yr and over. The prevalence of Heberden's nodes was greater in female than in male respondents and demonstrated a similar rise with increasing age.The prevalence of "probable" gout, based on available clinical information was 0.5 per cent for male and 0.3 per cent for female subjects age 4 yr and over having serum uric acid determinations. The highest rates were observed in subjects in the age range 40-59 yr.The prevalence rates for a history of rheumatic fever and / or chorea were similar for male and female subjects age 6 yr and over, 0.8 per cent in the case of rheumatic fever and 0.1 per cent in the case of chorea. A history of chorea was not obtained among respondents under age 20. Physical evidence of rheumatic heart disease was recorded in all age groups and was slightly more prevalent in females, 0.6 per cent as compared to 0.4 per cent in males.Comparisons of the results of this investigation with those of other population studies have been made although the interpretation of any differences or similarities is inherently limited by methodological problems and observer variation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33324/1/0000720.pd
Galaxy and Mass Assembly (GAMA): Variation in Galaxy Structure Across the Green Valley
Using a sample of 472 local Universe (z < 0.06) galaxies in the stellar mass range
10.25 < log M*/MG < 10.75, we explore the variation in galaxy structure as a function of morphology and galaxy colour. Our sample of galaxies is sub-divided into red, green and blue colour groups and into elliptical and non-elliptical (disk-type) morphologies.
Using KiDS and VIKING derived postage stamp images, a group of eight volunteers visually classified bars, rings, morphological lenses, tidal streams, shells and signs of merger activity for all systems. We find a significant surplus of rings (2.3σ) and lenses (2.9σ) in disk-type galaxies as they transition across the green valley. Combined, this implies a joint ring/lens green valley surplus significance of 3.3σ relative to equivalent disk-types within either the blue cloud or the red sequence. We recover a bar fraction of ∼ 44% which remains flat with colour, however, we find that the presence of a bar acts to modulate the incidence of rings and (to a lesser extent) lenses, with rings in barred disk-type galaxies more common by ∼ 20 − 30 percentage points relative to their unbarred counterparts, regardless of colour. Additionally, green valley disk-type galaxies with a bar exhibit a significant 3.0σ surplus of lenses relative to their blue/red analogues. The existence of such structures rules out violent transformative events as the primary end-of-life evolutionary mechanism, with a more passive scenario the favoured candidate for the majority of galaxies rapidly transitioning across the green valley.

Creative destruction in science
Drawing on the concept of a gale of creative destruction in a capitalistic economy, we argue that initiatives to assess the robustness of findings in the organizational literature should aim to simultaneously test competing ideas operating in the same theoretical space. In other words, replication efforts should seek not just to support or question the original findings, but also to replace them with revised, stronger theories with greater explanatory power. Achieving this will typically require adding new measures, conditions, and subject populations to research designs, in order to carry out conceptual tests of multiple theories in addition to directly replicating the original findings. To illustrate the value of the creative destruction approach for theory pruning in organizational scholarship, we describe recent replication initiatives re-examining culture and work morality, working parents\u2019 reasoning about day care options, and gender discrimination in hiring decisions.
Significance statement
It is becoming increasingly clear that many, if not most, published research findings across scientific fields are not readily replicable when the same method is repeated. Although extremely valuable, failed replications risk leaving a theoretical void\u2014 reducing confidence the original theoretical prediction is true, but not replacing it with positive evidence in favor of an alternative theory. We introduce the creative destruction approach to replication, which combines theory pruning methods from the field of management with emerging best practices from the open science movement, with the aim of making replications as generative as possible. In effect, we advocate for a Replication 2.0 movement in which the goal shifts from checking on the reliability of past findings to actively engaging in competitive theory testing and theory building.

Vaccine breakthrough hypoxemic COVID-19 pneumonia in patients with auto-Abs neutralizing type I IFNs
Life-threatening `breakthrough' cases of critical COVID-19 are attributed to poor or waning antibody response to the SARS- CoV-2 vaccine in individuals already at risk. Pre-existing autoantibodies (auto-Abs) neutralizing type I IFNs underlie at least 15% of critical COVID-19 pneumonia cases in unvaccinated individuals; however, their contribution to hypoxemic breakthrough cases in vaccinated people remains unknown. Here, we studied a cohort of 48 individuals ( age 20-86 years) who received 2 doses of an mRNA vaccine and developed a breakthrough infection with hypoxemic COVID-19 pneumonia 2 weeks to 4 months later. Antibody levels to the vaccine, neutralization of the virus, and auto- Abs to type I IFNs were measured in the plasma. Forty-two individuals had no known deficiency of B cell immunity and a normal antibody response to the vaccine. Among them, ten (24%) had auto-Abs neutralizing type I IFNs (aged 43-86 years). Eight of these ten patients had auto-Abs neutralizing both IFN-a2 and IFN-., while two neutralized IFN-omega only. No patient neutralized IFN-ss. Seven neutralized 10 ng/mL of type I IFNs, and three 100 pg/mL only. Seven patients neutralized SARS-CoV-2 D614G and the Delta variant (B.1.617.2) efficiently, while one patient neutralized Delta slightly less efficiently. Two of the three patients neutralizing only 100 pg/mL of type I IFNs neutralized both D61G and Delta less efficiently. Despite two mRNA vaccine inoculations and the presence of circulating antibodies capable of neutralizing SARS-CoV-2, auto-Abs neutralizing type I IFNs may underlie a significant proportion of hypoxemic COVID-19 pneumonia cases, highlighting the importance of this particularly vulnerable population
Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020
We show the distribution of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three genomic nomenclature systems to all sequence data from the World Health Organization European Region available until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation, compare the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2
A Genome-Wide Association Study of Diabetic Kidney Disease in Subjects With Type 2 Diabetes
dentification of sequence variants robustly associated with predisposition to diabetic kidney disease (DKD) has the potential to provide insights into the pathophysiological mechanisms responsible. We conducted a genome-wide association study (GWAS) of DKD in type 2 diabetes (T2D) using eight complementary dichotomous and quantitative DKD phenotypes: the principal dichotomous analysis involved 5,717 T2D subjects, 3,345 with DKD. Promising association signals were evaluated in up to 26,827 subjects with T2D (12,710 with DKD). A combined T1D+T2D GWAS was performed using complementary data available for subjects with T1D, which, with replication samples, involved up to 40,340 subjects with diabetes (18,582 with DKD). Analysis of specific DKD phenotypes identified a novel signal near GABRR1 (rs9942471, P = 4.5 x 10(-8)) associated with microalbuminuria in European T2D case subjects. However, no replication of this signal was observed in Asian subjects with T2D or in the equivalent T1D analysis. There was only limited support, in this substantially enlarged analysis, for association at previously reported DKD signals, except for those at UMOD and PRKAG2, both associated with estimated glomerular filtration rate. We conclude that, despite challenges in addressing phenotypic heterogeneity, access to increased sample sizes will continue to provide more robust inference regarding risk variant discovery for DKD.Peer reviewe
Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
