Evaluating the impact on hospital acquired pressure injury/ulcer incidence in a United Kingdom NHS Acute Trust from use of sub‐epidermal scanning technology
Authors: Nightingale Pippa , Musa Louisa 
Published: July 2021

AbstractBackgroundThe incidence of pressure injury/ulcers is persistent despite multiple prevention strategies in hospitals across the globe. Current standard of pressure injury/ulcer care supported by subjective skin tissue assessments, risk assessment tools and clinical judgement is ineffective in consistent pressure injury/ulcer prevention.AimA pragmatic study, aligning with SQUIRE guidelines, was conducted at Chelsea and Westminster hospitals to measure the impact of adding scanning technology to the prevailing standard of care pathway on the incidence of category 2–4 hospital‐acquired pressure injury/ulcers.MethodsSix hundred and ninety‐seven mixed‐population patients at risk for pressure injuries/ulcers with a Waterlow score of ≥10 and a mean age ≥65 years were enrolled across four wards over a 6‐month period. Scanning technology was added to the prevailing standard of care as a device adjunctive to clinical judgement for the detection of deep and early‐stage pressure‐induced tissue damage. Ward staff completed comprehensive device training by the device manufacturer. Clinical interventions were initiated by clinical judgement informed by injury/ulcer risk assessments, skin and tissue assessments and scanner readings. Incidence of reportable category 2–4 pressure injuries/ulcers from the prior 12‐month period from the same wards were used as a control comparator population. All diagnosed category 2–4 pressure injuries/ulcers, unstageable and deep‐tissue injuries were recorded.ResultsPrior study 12‐month pressure injury/ulcer incidence was 0.6% (5/892 patients) in ward A, 4.4% (9/206 patients) in Ward B, 1.1% (12/1,123 patients) in Ward C and 2.6% (16/625 patients) in Ward D. Two pressure injury/ulcers in Ward B were recorded during the study. Zero pressure injuries/ulcers were recorded in the remaining three wards resulting in an 81% incidence reduction across all four wards. Improved clinical decisions from clinical judgement based on Sub‐Epidermal Moisture (SEM) Scanner data were reported in 83% patients (n=578/697).ConclusionImplementing scanning technology into routine clinical practice achieves consistent reductions in pressure injury/ulcer incidence.

AbstractAims and objectivesTo investigate the possible association between hyponatremia and falls, in a sample of hospitalised adult patients.BackgroundIn‐hospital falls are a problem of major importance, provoking a significant decline in the quality of life of many patients. Recent studies have identified a relationship between such falls and the presence of hyponatremia.DesignAnalytical retrospective observational case‐control study.MethodsThe study population consisted of hospitalised patients who had suffered an in‐hospital fall during the period 2014–2016. For each case, two controls who had not suffered any such fall were recruited. These cases and controls were matched according to gender, age, hospitalisation unit and date of admission. Study data were obtained from the hospital’s record of falls, regarding the patients’ socio‐demographic factors, physical and psychological conditions and blood levels of sodium, potassium, urea and creatinine. The study is reported in accordance with STrengthening the Reporting of OBservational studies in Epidemiology guidelines.ResultsThe study sample consisted of 555 patients (185 cases and 370 controls). Hyponatraemia was detected in 57 cases (30.8%). A statistically significant relationship was found between the presence of hyponatraemia and the occurrence of falls: OR = 2.04. Other risk factors for falls were hypercreatinaemia OR 2.49, hyperuraemia OR 1.82, disorientation, need for ambulatory assistance and longer hospital stay.ConclusionsFrom the study findings, we conclude that hyponatraemia is a predictor of falls by acute hospitalised patients. Further research is needed on the relationship between hypercreatinaemia, hyperuraemia and falls.Relevance to clinical practiceThe assessment of risk factors for falls, such as hyponatraemia, can alert us to the possibility of this event occurring and facilitate the implementation of preventive measures. This parameter should be included as a significant new factor in assessment instruments designed to assess the risk of falls, thus enhancing the reliability and diagnostic validity of these instruments.
Bank survival around the world: A meta‐analytic review
Authors: Kočenda Evžen , Iwasaki Ichiro 
Published: July 2021

AbstractBank survival is essential to economic growth and development because banks mediate the financing of the economy. A bank's overall condition is often assessed by a supervisory rating system called CAMELS, an acronym for the components Capital adequacy, Asset quality, Management quality, Earnings, Liquidity, and Sensitivity to market risk. Estimates of the impact of CAMELS components on bank survival vary widely. We perform a metasynthesis and metaregression analysis (MRA) using 2120 estimates collected from 50 studies. In the MRA, we account for uncertainty in moderator selection by employing Bayesian model averaging. The results of the synthesis indicate an economically negligible impact of CAMELS variables on bank survival; in addition, the effect of bank‐specific, (macro)economic, and market factors is virtually absent. The results of the heterogeneity analysis and publication bias analysis are consistent in terms that they do not find an economically significant impact of the CAMELS variables. Moreover, best practice estimates show a small economic impact of CAMELS components and no impact of other factors. The study concludes that caution should be exercised when using CAMELS rating to predict bank survival or failure.
Taking diversity seriously: Within‐group heterogeneity in African American extended family support networks
Authors: Taylor Robert Joseph , Chatters Linda M. , Cross Christina J. 
Published: July 2021

AbstractObjectiveThis study examined the correlates of involvement in extended family social support networks among African Americans.BackgroundPrevious literature has documented the importance of informal social support from extended family members for the African American population. Most research has investigated black‐white differences in network involvement or has focused on impoverished African American families. Both approaches conceal important within‐group variation in participation among the total African American population.MethodThis study relied on nationally representative data from the African American sub‐sample of the National Survey of American Life (n = 3538). It employed ordinary least squares regression analysis to examine the sociodemographic and family factors that are associated with four key measures of involvement in extended family support networks: receiving and providing extended family support, frequency of family contact, and degree of subjective closeness.ResultsAfrican Americans routinely interacted with members of their family, displayed a high degree of family closeness, and exchanged support fairly frequently. Findings also revealed significant variation in network involvement by sociodemographic characteristics: women, younger adults, and Southerners were typically most involved; individuals who experienced greater material hardship, were previously incarcerated, or served in the military reported less involvement. Results also showed that family closeness and family contact were particularly salient factors shaping the extent to which network members engaged in support exchanges.ConclusionThe magnitude of within‐group heterogeneity in network involvement underscores the importance of considering issues of intragroup diversity in the developing literature on African American extended family networks.
Measurement error in US regional economic data
Authors: Carpenter Craig Wesley , Van Sandt Anders , Loveridge Scott 
Published: July 2021

AbstractEstimates of publicly suppressed and unrevised regional economic data produce error and potentially bias statistical inference. This article estimates measurement error in suppressed cell estimated data sets (SCEDs) relative to unsuppressed federal administrative data. In a cross section, coefficient estimates based on relatively aggregated SCEDs are attenuated by about 31%, increasing to 50% in panel data. Coefficient estimates based on less‐aggregated SCEDs are not generally reliable. A review of the limited options for identification emphasizes both the systemic limitations suppression places on research inference and the value of retrospective revisions in confidential data, highlighting the importance of confidential data access and use.

Published: July 2021

AbstractThis study is among the first to investigate whether patterns of access to basic services could explain the disproportionately severe impact of COVID‐19 in slums. Using geolocated containment zones and COVID‐19 case data for Mumbai, India's most populous city, we find that cases and case fatality rates are higher in slums compared with formal residential buildings. Our results show that access to toilets for men is associated with lower COVID‐19 prevalence. However, the effect is opposite in the case of toilets for women. This could be because limited hours for safely using toilets and higher waiting times increase the risk of exposure, and women and children sharing toilet facilities results in crowding. Proximity to water pipelines has no effect on prevalence, likely because slumdwellers are disconnected from formal water supply networks. Indoor crowding does not seem to have an effect on case prevalence. Finally, while police capacity—measured by number of police station outposts—is associated with lower prevalence in nonslum areas, indicating effective enforcement of containment, this relationship does not hold in slums. The study highlights the urgency of finding viable solutions for slum improvement and upgrading to mitigate the effects of contagion for some of the most vulnerable populations.

SummaryThe outbreak of the novel coronavirus disease 2019 (COVID‐19) changed lifestyles worldwide and subsequently induced individuals’ sleep problems. Sleep problems have been demonstrated by scattered evidence among the current literature on COVID‐19; however, little is known regarding the synthesised prevalence of sleep problems (i.e. insomnia symptoms and poor sleep quality) for males and females separately. The present systematic review and meta‐analysis aimed to answer the important question regarding prevalence of sleep problems during the COVID‐19 outbreak period between genders. Using the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guideline and Newcastle–Ottawa Scale checklist, relevant studies with satisfactory methodological quality searched for in five academic databases (Scopus, PubMed Central, ProQuest, Web of Science , and EMBASE) were included and analysed. The protocol of the project was registered in the International Prospective Register of Systematic Reviews (PROSPERO; identification code CRD42020181644). A total of 54 papers (N = 67,722) in the female subgroup and 45 papers (N = 45,718) in the male subgroup were pooled in the meta‐analysis. The corrected pooled estimated prevalence of sleep problems was 24% (95% confidence interval [CI] 19%–29%) for female participants and 27% (95% CI 24%–30%) for male participants. Although in both gender subgroups, patients with COVID‐19, health professionals and general population showed the highest prevalence of sleep problems, it did not reach statistical significance. Based on multivariable meta‐regression, both gender groups had higher prevalence of sleep problems during the lockdown period. Therefore, healthcare providers should pay attention to the sleep problems and take appropriate preventive action.
Linking insect herbivory with plant traits: Phylogenetically structured trait syndromes matter
Authors: Těšitel Jakub , Tahadlová Markéta , Lepš Jan , Hölzel Norbert 
Published: July 2021

AbstractQuestionsHerbivory is a fundamental ecological interaction underlying energy and mass flow between primary producers and consumers. Ecological theory describes plant biomass quality in terms of food for herbivores as a functional effect trait. We asked how leaf functional traits affect insect herbivory in a species‐rich meadow community.LocationČertoryje National Nature Reserve, Bílé Karpaty (White Carpathians) Protected Landscape Area, Czech Republic.MethodsWe assessed herbivory of 24 plant species co‐occurring in a species‐rich semi‐natural grassland by measuring herbivore damage caused by leaf‐chewing insects. Identification of trait–herbivory links was conducted by a comparative analysis based on a phylogenetically informed regression.ResultsPlant species strongly differed in leaf‐chewer herbivory. Interspecific differences in herbivory and most traits displayed a strong phylogenetic signal associated with the deep evolutionary split between monocot graminoids and dicot forbs. There were also pronounced correlations among individual traits. Herbivory was tightly related to an intercorrelated trait set describing fibre composition and Ca content. There was also a less pronounced negative effect of leaf biomass C:N ratio on herbivory. However, the observed association between traits and herbivory was phylogenetically structured in agreement with the univariate tests of phylogenetic signal.ConclusionHerbivory was associated with a whole syndrome of intercorrelated traits, among which it is not possible to choose a single best trait predictor. Moreover, the principal pattern in this trait syndrome was related to a macro‐evolutionary singularity. Such linkage among an ecosystem process, traits, and phylogeny complicates linking ecosystem processes with particular functional traits and may also occur elsewhere in natural ecosystems.
Women's embroidered self‐portraiture in the late 18th century: Authorship, agency, and artistry
Authors: Strobel Heidi A. 
Published: July 2021

AbstractIn 18th‐century Europe and North America, portraiture satisfied multiple purposes: the creation of individual and/or familial identity, verisimilitude, and the decoration of a home. Self‐portraiture, a likeness of an artist created by the artist, often served as an artist's statement that articulated professional goals. Textile self‐portraits, however, unlike the more popular sculpted and painted versions, have been neglected by scholars of the early modern period. Three examples were made by English embroiderers Mary Linwood (1755–1845), Mary Knowles (1733–1807), and Marie Thérèsa Lasselle (1735–1819), a New World settler whose family traded with Native American peoples on behalf of the British. Because the lives of these women are poorly documented, their embroidered self‐portraits were more than just a likeness, for they served an important autobiographical function. The iconography and materiality of these portraits conveys information about late 18th‐century beliefs about femininity, self‐expression, and individual agency.

Published: July 2021

AbstractHumoral and cellular immune responses provide animals with major defences against harmful pathogens. While it is often assumed that immune genes undergo rapid diversifying selection, this assumption has not been tested in many species. Moreover, it is likely that different classes of immune genes experience different levels of evolutionary constraint, resulting in varying selection patterns. We examined the evolutionary patterns for a set of 91 canonical immune genes of North American monarch butterflies (Danaus plexippus), using as an outgroup the closely related soldier butterfly (Danaus eresimus). As a comparison to these immune genes, we selected a set of control genes that were paired with each immune for approximate size and genomic location. As a whole, these immune genes had a significant but modest reduction in Tajima's D relative to paired‐control genes, but otherwise did not show distinct patterns of population genetic variation or evolutionary rates. When further partitioning these immune genes into four functional classes (recognition, signalling, modulation, and effector), we found distinct differences among these groups. Relative to control genes, recognition genes exhibit increased nonsynonymous diversity and divergence, suggesting reduced constraints on evolution, and supporting the notion that coevolution with pathogens results in diversifying selection. In contrast, signalling genes showed an opposite pattern of reduced diversity and divergence, suggesting evolutionary constraints and conservation. Modulator and effector genes showed no statistical differences from controls. These results are consistent with patterns found in immune genes in fruit flies and Pieris butterflies, suggesting that consistent selective pressures on different classes of immune genes broadly govern the evolution of innate immunity among insects.

AbstractThere is increasing awareness that interactions between plants and insects can be mediated by microbial symbionts. Nonetheless, evidence showing that symbionts associated with organisms beyond the second trophic level affect plant‐insect interactions are restricted to a few cases belonging to parasitoid‐associated bracoviruses. Insect parasitoids harbour a wide array of symbionts which, like bracoviruses, can be injected into their herbivorous hosts to manipulate their physiology and behaviour. Yet, the function of these symbionts in plant‐based trophic webs remains largely overlooked. Here, we provide the first evidence of a parasitoid‐associated symbiont belonging to the group of ichnoviruses which affects the strength of plant‐insect interactions. A comparative proteomic analysis shows that, upon parasitoid injection of calyx fluid containing ichnovirus particles, the composition of salivary glands of caterpillars changes both qualitatively (presence of two viral‐encoded proteins) and quantitatively (abundance of several caterpillar‐resident enzymes, including elicitors such as glucose oxidase). In turn, plant phenotypic changes triggered by the altered composition of caterpillar oral secretions affect the performance of herbivores. Ichnovirus manipulation of plant responses to herbivory leads to benefits for their parasitoid partners in terms of reduced developmental time within the parasitized caterpillar. Interestingly, plant‐mediated ichnovirus‐induced effects also enhance the performances of unparasitized herbivores which in natural conditions may feed alongside parasitized ones. We discuss these findings in the context of ecological costs imposed to the plant by the viral symbiont of the parasitoid. Our results provide intriguing novel findings about the role played by carnivore‐associated symbionts on plant‐insect‐parasitoid systems and underline the importance of placing mutualistic associations in an ecological perspective.
Food for everyone: Differential feeding habits of cryptic bat species inferred from DNA metabarcoding

Published: July 2021

AbstractEcological theory postulates that niches of co‐occurring species must differ along some ecological dimensions in order to allow their stable coexistence. Yet, many biological systems challenge this competitive exclusion principle. Insectivorous bats from the Northern Hemisphere typically form local assemblages of multiple species sharing highly similar functional traits and pertaining to identical feeding guilds. Although their trophic niche can be accessed with unprecedented details using genetic identification of prey, the underlying mechanisms of resource partitioning remain vastly unexplored. Here, we studied the differential diet of three closely‐related bat species of the genus Plecotus in sympatry and throughout their entire breeding season using DNA metabarcoding. Even at such a small geographic scale, we identified strong seasonal and spatial variation of their diet composition at both intra‐ and interspecific levels. Indeed, while the different bats fed on a distinct array of prey during spring, they showed higher trophic niche overlap during summer and fall, when all three species switched their hunting behaviour to feed on few temporarily abundant moths. By recovering 19 ecological traits for over 600 prey species, we further inferred that each bat species used different feeding grounds and hunting techniques, suggesting that niche partitioning was primarily habitat‐driven. The two most‐closely related bat species exhibited very distinct foraging habitat preferences, while the third, more distantly‐related species was more generalist. These results highlight the need of temporally comprehensive samples to fully understand species coexistence, and that valuable information can be derived from the taxonomic identity of prey obtained by metabarcoding approaches.
Behavioral responses of humpback whales to biopsy sampling on a breeding ground: the influence of age‐class, reproductive status, social context, and repeated sampling
Authors: Garrigue Claire , Derville Solène 
Published: July 2021

AbstractThe short‐term response of humpback whales to boat approach and remote biopsy sampling was investigated in a breeding ground according to age‐class, sex, female reproductive status, social context, sampling system, habitat, and repeated sampling with more than 20 years of data. In a total of 2,248 observed behavioral responses to biopsy sampling, 58.7% showed no response, 40.7% were considered to be weak or moderate responses, and only 0.5% were considered to be strong. No significant difference was found between the response of calves (young‐of‐the‐year) and that of adults, whereas juveniles responded significantly more strenuously. The response of adult whales was influenced by sex, female reproductive status, and social context. Mothers showed the most frequent response to the boat approach, but the weakest response to the biopsy sampling itself, whereas nonlactating females had the strongest response to biopsy sampling. Males responded less when sampled within a competitive group. Repeated sampling of individual adults resulted in decreasing intensity of responses across years. This comprehensive assessment has implications for management authorities, notably in approving research permits for sampling different age classes on breeding grounds.
