Post‐cardioversion atrial stunning – Not to be forgotten
Authors: Kurt Merve , Naqvi Tasneem Z. 
Published: January 2023

AbstractWe present a case of a 60‐year‐old male who was found to be in atrial fibrillation during routine evaluation. Anticoagulation was initiated for 36 h and he was referred for TEE‐guided electrical cardioversion. There was no thrombus identified in the left atrial appendage, however, the appendage was large and had a tongue‐like accessory lobe along with spontaneous contrast in the left atrium and its appendage. TEE probe was not withdrawn, patient underwent successful cardioversion with 200 joules and developed a marked increase in left atrial and left atrial appendage spontaneous contrast along with the development of tear drop shaped thrombus in the left atrial appendage immediately after cardioversion, which rapidly became more dense. There was an associated marked decrease in appendage velocities. Patient was hospitalized to initiate low molecular weight heparin. This case highlights the need for vigilance in patients with an unknown duration of atrial fibrillation, who have received a short duration of anticoagulant therapy and who have adverse appendage anatomy as thrombus may develop immediately after cardioversion despite anticoagulation.

AbstractIntroductionThalassemias are common monogenic autosomal recessive hemoglobin disorders. The usually asymptomatic heterozygotes (β‐thalassemia traits, βTT) may rarely develop non‐transfusion‐dependent‐thalassemia (NTDT) due to co‐inheritance of supernumerary α‐globin genes. Literature on phenotypic/genotypic features of these rare combinations is limited.Materials and MethodsWe studied the demographic, clinical, and laboratory data from 47 persons with co‐inherited βTT + supernumerary α‐globin genes. HBB mutations were tested for by ARMS‐PCR and/or Sanger sequencing, ααα(anti3.7)/ααα(anti4.2) and deletional α‐thalassemia testing by multiplex gap‐PCRs, and Xmn1Gγ genotyping by PCR‐RFLP.ResultsThe 47 cases comprised 0.08% of 61 010 hemoglobinopathy screenings during the study period. Mean age was 31.9 ± 14.7 years (range 5.5–83 years), with 57.4% males. Thirty (63.8%) had NTDT‐phenotype, 16 (34%) were asymptomatic/minimally symptomatic, and 1 became transfusion‐dependent at the age of 20 years. Anemia/pallor and jaundice were the commonest complaints (76% each); 40% had required blood transfusions. Twenty‐one had splenomegaly, 14 had hepatomegaly. Mean hemoglobin was 9.0 ± 1.9 g/dl (range 4.0–13.0). HbA2 was 5.1 ± 0.7% (3.4%–6.3%) and HbF% 4.2 ± 3.2% (0.5%–18.4%). Forty‐four (93.6%) had αααanti3.7, while 3 (6.4%) had αααanti4.2 triplications. HBB:c.92+5G>C (47%), HBB:c.27_28insG (14.9%), and HBB:c.47G>A (8.5%) were the commonest β‐globin mutations. One case showed HBB:c.‐138C>T (β++), while the rest had β0 or severe‐β+ mutations. Symptomatic cases had significantly lower hemoglobins and higher HbF% than asymptomatic ones.ConclusionThis largest Indian and globally second‐largest study reports the βTT + ααα4.2 state for the first time in such genotypically‐complex Indian cases. Supernumerary α‐genes should be suspected in all βTT with disproportionate clinical symptoms, mild‐to‐moderately elevated HbF, and unexplained anisopoikilocytosis.
Ordeal by innocence in the big‐data era: Intended data breach disclosure, unintended real activities manipulation
Authors: Liu Jinyu , Ni Xiaoran 
Published: January 2023

AbstractWe demonstrate an unintended consequence of mandatory disclosure of data breaches: the distortion of firms' real business activities. Employing the staggered adoption of data breach disclosure laws across various US states, we show that mandatory disclosure exacerbates CEOs' real earnings manipulation through production and operation management, which is more pronounced for firms of which the outbreak of data breaches is more of a concern and under stronger short‐term market pressure. The law adoption is associated with higher stock price crash risk and fewer patenting activities. Our findings reveal side effects of certain customer‐protection regulations in view of dampened information quality.
Do new CEOs really care about innovation?
Authors: Ahmad Wasim , Farag Hisham , Wang Yaopeng 
Published: January 2023

AbstractThis study asks whether new chief executive officers (CEOs) care about innovation postturnover. Using a large sample of Chinese listed firms between 2008 and 2019, our identification strategy relies on the exogenous variation in CEO turnovers. Our difference‐in‐difference estimates indicate that new CEOs improve R&D efficiency and generate more and higher quality patents. We further show that this positive effect is more pronounced when CEOs have longer career horizons and overseas experience. Overall, our findings indicate that CEO turnover represents an effective mechanism for fostering innovation and new CEOs indeed care about innovation. Our results could benefit several groups of stakeholders with respect to CEO selection process.
The application of the Theory of Critical Distances to nonhomogeneous materials
Authors: Marsavina Liviu , Sapora Alberto , Susmel Luca , Taylor David 
Published: January 2023

AbstractThe Theory of Critical Distances (TCD) has undoubtedly represented a breakthrough in the brittle failure assessment of engineering materials containing defects, crack, or notches. The basic idea on which the simplest formulation of the TCD is based is to evaluate an effective stress at a characteristic distance from the tip of the defect/crack/notch and compare it with an inherent fracture strength. Is the critical distance related to the material (micro) structure? Whereas a correlation was already proved for homogeneous materials, the current attention to nonhomogeneous ones has brought the question back to the fore. The goal of the present work is therefore twofold: (i) to extend the use of the TCD, through the simple yet effective Point Method (PM), for the static failure assessment of inhomogeneous materials, such as cellular, biological, and additively manufactured (AM) materials; and (ii) to look for a correlation between critical distance and internal (micro) structure.

Abstract

Changes in phosphorus concentrations affect periphytic diatom composition in streams, yet we rarely observe strong relationships between diatom richness and phosphorus. In contrast, changes in conductivity are strongly associated with differences in both diatom composition and richness. We hypothesised that we could better understand the mechanisms that control the phosphorus–richness relationship by examining relationships between phosphorus and the occurrence of individual diatom taxa, comparing these with relationships between conductivity and taxon occurrence, and documenting how niche breadths of taxa affect richness patterns.

We estimated relationships between phosphorus and taxon occurrence using DNA metabarcoding data of diatoms collected from 1,811 sites distributed across the conterminous U.S.A. and contrasted patterns in these relationships with those between conductivity and taxon occurrence.

The distribution of taxon optima for phosphorus was bimodal, with most optima located at either the maximum or minimum observed phosphorus concentration. The distribution of taxon optima for conductivity was unimodal. Niche breadths of taxa for phosphorus and for conductivity both generally increased with optimum values.

The distribution of conductivity optima gave rise to a prominent hump‐shaped relationship between richness and conductivity. The relationship between richness and phosphorus was also slightly hump‐shaped, but this relationship would not be expected from the bimodal distribution of optima. Instead, we determined that broad niche breadths caused the hump‐shaped relationship between richness and phosphorus.

Our results highlight the nuanced effects that increased P loadings exert on diatom assemblages in rivers and streams and identify reasons that weak relationships between taxon richness and increased phosphorus have been observed. These findings allow us to better describe how excess phosphorus and subsets of taxa and their niche breadths contribute to patterns of taxa richness in diatom assemblages, and to improve the tools used to manage phosphorus pollution.
Are diatom community assembly processes scale invariant in streams?
Authors: Soininen Janne 
Published: January 2023

Abstract

Biological communities are structured by deterministic and stochastic factors often regarded to as community assembly processes. Deterministic factors comprise environmental filtering and biotic interactions while stochastic factors include random dispersal and ecological drift. Earlier research suggests that the relative importance of assembly processes may vary with scale. This is because biotic interactions typically occur at fine spatial scales, whereas heterogeneous environment filters species more efficiently at larger scales. The aim of this study was to investigate whether stream diatom community assembly processes varied among three spatial scales, ranging from within‐site scales to across drainage‐system scales in Finland.

The smallest spatial scale was a single riffle where a local community was defined as diatoms living on a single stone. The next larger spatial scale was a drainage system while the largest spatial scale comprised the pooled data from the eight drainage systems. To test whether the diatom communities were stochastically or deterministically assembled, the null model approach based on Raup–Crick dissimilarities (βRC) was used. Redundancy analyses were also run to visualise diatom community variation and to investigate the main environmental variables associated with community variation.

At the within‐riffle scale, mean and median βRC values were approaching −1, suggesting that environmental filtering shaped the communities. At the within‐drainage system scale, mean and median βRC values were also negative, but notably larger than within riffles. Across drainages, βRC values were at similar level to the within‐drainage system scale. At the riffle scale, water depth and light had the strongest influence on diatom community variation followed by current velocity along the stream. At the drainage scale, conductivity, pH, latitude, total phosphorus, and water colour had the largest influence on diatom community variation.

Overall, negative Raup–Crick dissimilarities indicated that environmental filtering dominated diatom community assembly at all scales but especially at small, within‐riffle scales. There was no consistent support for limiting similarity even at the smallest scales and the effect of stochastic, dispersal‐related factors became stronger at larger scales. These results support the idea that chemical conditions in streams are decisive factors for freshwater diatom biodiversity especially at regional scales.
Effects of climate on fall migration phenology of monarch butterflies departing the northeastern breeding grounds in Canada
Authors: Ethier Danielle M. , Mitchell Greg W. 
Published: January 2023

AbstractMonarch butterflies (Danaus plexippus) undergo an iconic multi‐generational migration, traveling thousands of kilometers from the summer breeding grounds in southern Canada to overwintering sites in central Mexico. This migration phenomena can be affected by climate change, which may have important implications on fitness and ultimately populations status. We investigated the long‐term trends in fall migration phenology of monarchs using a 25‐year dataset collected along the coast of Lake Erie in Ontario, Canada. We also investigated local long‐term trends in weather covariates that have the potential to influence migration phenology at this site. Patterns in standardized daily counts of monarchs were compared with local weather covariates using two methods (i.e., monthly averages and moving windows) to assess difference in outputs between analytical approaches. Our results suggest that monarch migration timing (migration midpoint, average peak, first peak, and late passage) and weather covariates have been consistent over time, in direct contrast to a similar study in Cape May, New Jersey, which showed a significant increase in both fall temperature and a 16‐ to 19‐day shift in monarch migration timing. Furthermore, our results differed between analytical approaches. With respect to annual variability in air temperature, our monthly average analysis suggested that for each degree increase in September air temperature, late season passage would advance 4.71 days (±1.59 SE, p = .01). However, the moving window analysis suggested that this result is likely spurious and found no significant correlations between migration timing and any weather covariates. Importantly, our results caution against extrapolating the effects of climate change on the migration phenology of the monarch across study regions and the need for more long‐term monitoring efforts to better understand regional drivers of variability in migration timing.

AbstractBackgroundPatterns of vitamin D intake are relatively unexplored among women living with HIV, despite its importance for women's health. We compared vitamin D dietary and supplement intakes in women with HIV and population‐based national controls and investigated barriers to intake.MethodsIn this case–control study, women with HIV in the Children and Women: AntiRetrovirals and Markers of Aging (CARMA) cohort were matched with Canadian Multicentre Osteoporosis Study (CaMos) controls. Participants were queried for vitamin D in dairy consumption, supplementation/dosage, and sociodemographic variables. We assessed barriers to supplementation and factors associated with dietary intake by regression modelling.ResultsNinety‐five women living with HIV were age‐matched to 284 controls. Women with HIV had lower income and bone mineral density and were more likely to smoke, take multiple medications and be non‐white. Vitamin D dietary intake was lower in women living with HIV versus controls [0.76 vs. 1.79 μg/day; adjusted odds ratio (aOR) for greater than or equal to median intake 0.29 (0.12–0.61), p = 0.002], but any supplementation was higher [62.2% vs. 44.7%; aOR = 3.44 (95% CI: 1.16–11.00), p = 0.03]. Total vitamin D intake was similar between groups. Smoking was associated with no supplementation; non‐white ethnicity and low income were related to lower dietary intake.ConclusionsWomen living with HIV showed lower dietary vitamin D intake but higher supplementation rates, suggesting that care providers are promoting supplementation. Women living with HIV who smoke, have low incomes and are non‐white may particularly benefit from targeted efforts to improve vitamin D intake.

Abstract
The exploration of biodiversity has predominantly been based on taxonomic measures, whereas functional diversity, a key component of biodiversity, is comparatively understudied. Therefore, studies simultaneously investigating patterns of taxonomic and functional diversity change in biological communities are of increasing interest.
We collated high‐resolution macroinvertebrate and environmental data from 70 boreal headwater stream sites across three European countries (Germany, Finland, Sweden) to (1) investigate seasonal variation in taxonomic diversity, functional diversity, and redundancy, and (2) identify their potential drivers of spatial and seasonal variation.
Seasonal changes in boreal macroinvertebrate taxonomic diversity were decoupled from changes in functional diversity. Seasonal shifts in environmental conditions, including acidity and nutrient variability, drove fluctuations in taxonomic diversity which were far more pronounced than those of functional diversity.
Seasonal shifts in environmental conditions including variation in the quantity, quality, and state of organic carbon (dissolved vs particulate) facilitate an exchange of taxa, leading to taxonomically unique communities that exploit the pool of available seasonal resources. Thus, similar levels of functional diversity across seasons—even as taxonomic diversity changes—suggest limited differences in interspecific changes in community function, potentially indicating functional resistance rooted in redundancy.
We highlight the spatial and seasonal discrepancies of freshwater communities, emphasising the need for both taxonomic and functional diversity patterns to be assessed in future biodiversity monitoring programmes.
Clinical nurses' patient safety competency, systems thinking and missed nursing care: A cross‐sectional survey
Authors: Chang Hyoung Eun , Manojlovich Milisa 
Published: January 2023

AbstractAimThe aim of this study was to examine the relationships among patient safety competency, systems thinking and missed nursing care.BackgroundPatient safety competency and systems thinking are important nurse attributes that promote patient safety. Missed nursing care is known to negatively impact patient safety. However, how nurses' patient safety competency and systems thinking relate to missed nursing care is unknown.MethodsA cross‐sectional survey design was used to collect data from nurses practicing in two general hospitals in South Korea. Data were collected between 3 March and 17 April 2020. Questionnaires were distributed to nurses providing direct care in general and specialty units. Patient safety competency, systems thinking and missed nursing care were measured using reliable and valid instruments. A total of 432 complete sets of data were used in final analysis.ResultsHigher patient safety competency of nurses was associated with lower missed nursing care. Systems thinking partially mediated the relationship between knowledge of patient safety competency and missed nursing care, and attitudes of patient safety competency and missed nursing care.ConclusionsThe knowledge, skills and attitudes sub‐scales of patient safety competency showed somewhat different effects in the relationship between missed nursing care and systems thinking, suggesting that each attribute may tap into a separate aspect of patient safety.

Published: January 2023

AbstractAimTo summarize the omics results of symptomatic research that can help nurses identify intervention targets and design precision interventions for pain, mental health, cognitive impairment, sleep disorder, fatigue, lymphedema, and quality of life, so as to provide a comprehensive summary of help and inspire to precision nursing.MethodsCINAHL, PubMed, Web of Science, and ScienceDirect databases were searched. Retrieval time was from January 2012 to December 2021. Symptomatology research applying omics that can be used to guide nurses in designing targeted interventions was included.ResultsForty‐six studies were included in the final review. Symptomatology research that can be integrated with nursing science to develop precision nursing focused on pain, mental health, cognitive impairment, sleep disorder, fatigue, lymphedema, and quality of life. Most studies were related to cognitive impairment (n = 10; 21.74%), pain (n = 9; 19.57%), and mental health (n = 8; 17.39%). Moreover, the included studies involved various omics technologies, such as whole genome, epigenome, transcriptome, proteome, and metabolome.ConclusionThe rapid development of various omic technologies promotes symptomatology research, which can help nurses fully understand the information of patients. Phenotypic characteristics and biomarkers shown in symptomatology research help nurses identify intervention targets and develop individualization interventions, so as to prevent and reduce symptoms and improve the quality of life.Implication for nursing and health policyThis scoping review is the first synthesis of all peer‐reviewed literature to summarize and provide important information and references from the omic results of symptomatology studies to develop precision nursing, highlighting the status and development of precision nursing. Nursing education policies should introduce the development and importance of precision nursing. Further research could consider investing more attention in precision nursing. Nursing researchers can carry out some studies applying omics technology to explore more biomarkers, helping guide the formulation of clinical intervention for symptoms.
One judge to rule them all: Single‐member courts as an answer to delays in criminal trials
Authors: Kalliris Konstantinos , Alysandratos Theodore 
Published: January 2023

AbstractThis paper is a discussion of whether single‐member judicial panels are an effective way of accelerating the delivery of criminal justice. We use a reform which introduced single‐member courts in Greece, where delays in court proceedings are common according to the European Justice Scoreboard and the European Court of Human Rights. We use a novel dataset of 1463 drug trafficking cases tried between June 2012 and January 2014. As our measure of efficiency we use the time to issue a decision, and we find that single‐member panels are as efficient as three‐member ones. We take advantage of a feature of the reform to control for several confounding factors and support a causal interpretation of our findings. We complement our analysis with a survey of 142 judges to guide our interpretation of the results.
