Published: March 2021

Abstract
Imidacloprid, a neonicotinoid pesticide, is used to prevent the spread of the hemlock woolly adelgid, currently affecting Eastern Hemlock trees across North America. When the pesticide is sprayed directly onto soil around infested trees (soil drenching), it can run off into aquatic systems, with potential negative effects on biota. Simultaneously, climate change may lead to faster pool drying, which acts as an additional stressor for sensitive species such as amphibians. We evaluated the sublethal effects of imidacloprid (10 ppb), and interaction with shorter hydroperiods on the larval behavior, growth, and survival of a model organism, the wood frog (Rana sylvatica). We performed 3 behavioral experiments evaluating swimming speed, time spent swimming, and distance the larvae swam. We found that larvae raised in 10 ppb imidacloprid or shorter hydroperiod did not differ in their swimming time, distance, and speed from nonexposed larvae. Naïve larvae exposed for 20 min to 10- to 500-ppb concentrations also showed similar performance to nonexposed larvae. However, when we applied a stimulus halfway through each experiment, we found that larvae exposed to 10 ppb imidacloprid (short and long term) swam shorter distances and spent less time swimming, suggesting that imidacloprid exposure may slow reaction time, potentially increasing the risk of predation. To minimize impacts on pool-breeding amphibians, imidacloprid application to combat the invasive hemlock woolly adelgid should use trunk injection and avoid soil drenching.

AbstractObjectiveTo explore treatment strategies for patients with positive margins after cervical cold knife conization (CKC) by estimating the risk of residual or recurrent CIN2 or worse (CIN2+).MethodsA retrospective study included 569 patients receiving CKC for CIN3 in Xiangya Hospital from January 2013 to December 2017. Demographic characteristics and test results were obtained before CKC, after CKC, at 6, 12, and 24 months, then annually thereafter. The primary end point was residual/recurrent CIN2+ post‐CKC.ResultsFourteen (2.46%) patients had residual/recurrent CIN2+ with a median time of occurrence at 12 months post‐CKC. Taking the average age and hrHPV viral load tested by Hybrid Capture 2 (HC2) as thresholds, the risk of residual/recurrent CIN2+ was higher in women aged over 40 years or with a baseline HC2 of 300 or more for the ratio of relative light units to positive cut‐off values. Patients with positive margins were at higher risk of residual/recurrent CIN2+ (hazard ratio 3.66, 95% confidence interval 1.25–10.71), especially when endocervix was involved. A total of 536 (94.20%) patients received HPV testing within 6 months after CKC. Patients with both positive HPV testing results and positive margins were at the highest risk of residual/recurrent CIN2+.ConclusionPatients with positive endocervical margins are at high risk for residual/recurrent CIN2+, independent of the severity of margins. HPV testing within 6 months after CKC may be a feasible triage strategy for these patients.

AbstractBenzo[a]pyrene (B[a]P) and polybrominated diphenyl ethers (PBDEs) are persistent environmental contaminants. The effects in organisms of exposures to binary mixtures of such contaminants remain obscure. Attenuated total reflection Fourier‐transform infrared (ATR‐FTIR) spectroscopy is a label‐free, non‐destructive analytical technique allowing spectrochemical analysis of macromolecular components, and alterations thereof, within tissue samples. Herein, we employed ATR‐FTIR spectroscopy to identify biomolecular changes in rat liver post‐exposure to B[a]P and BDE‐47 (2,2′,4,4′‐tetrabromodiphenyl ether) congener mixtures. Our results demonstrate that significant separation occurs between spectra of tissue samples derived from control versus exposure categories (accuracy = 87%; sensitivity = 95%; specificity = 79%). Additionally, there is significant spectral separation between exposed categories (accuracy = 91%; sensitivity = 98%; specificity = 90%). Segregation between control and all exposure categories were primarily associated with wavenumbers ranging from 1600 to 1700 cm−1. B[a]P and BDE‐47 alone, or in combination, induces liver damage in female rats. However, it is suggested that binary exposure apparently attenuates the toxic effects in rat liver of the individual contaminants. This is supported by morphological observations of liver tissue architecture on hematoxylin and eosin (H&E)‐stained liver sections. Such observations highlight the difficulties in predicting the endpoint effects in target tissues of exposures to mixtures of environmental contaminants.
An innovative use of electrochemically modified three‐dimensional carbon felt for a rapid recovery of gold from diluted chloride solution

Published: March 2021

AbstractBACKGROUNDThis study presents the novel use of modified Shipley‐activated carbon felt in an electrogenerative process via flow‐through batch recycle cell to recover gold, Au(III), from chloride solutions.RESULTSThe recovery of Au(III) was conducted in a batch recycle cell equipped with three‐dimensional activated carbon felt as a cathode and zinc as an anode. Several initial Au(III) concentrations (50, 100, 250, and 500 mg L−1) and different types of cathode materials (carbon felt and reticulated vitreous carbon) were used to evaluate the cell performance. Both the electrodes were at the same size (2.0 cm × 5.3 cm × 0.3 cm) and volume (3.18cm3). At optimum conditions, total Au(III) recovery was achieved with the use of activated carbon felt at a concentration of 500 mg L−1 within 30 min of operation with a flow rate of 50 mL min−1. This was achieved at a fractional conversion of 1.00, where all the 2894 mol of Au were fully deposited at the cathode. This can be ascribed to the massive surface area and high porosity of carbon felt. Carbon felt has a specific surface area of 1229 cm2g−1 and a porosity of 94.81%. The morphological and compositional studies of the electrodeposited Au(III) onto activated carbon felt cathode material were also carried out.CONCLUSIONIt is confirmed that Au(III) has been successfully deposited by cathodic reduction of Au(III) ions. © 2021 Society of Chemical Industry (SCI).
Wanted: A vocabulary for talking about involuntary behaviors associated with Lesch‐Nyhan disease
Authors: Robey Kenneth L. , Balboni Daniel C. 
Published: March 2021

AbstractLesch‐Nyhan disease (LND) is a rare genetic disorder with an unusual behavioral phenotype that includes severe and involuntary self‐injury requiring the near constant use of protective devices and, for some individuals, dental extraction. Often, the person with LND also engages in emotional self‐injury in the form of both self‐sabotage and behaviors directed toward others that will have a negative social consequence. When these self‐destructive behaviors present themselves, it is sometimes challenging for caregivers, professionals, or other observers to fully recognize their lack of volition. It is an even greater challenge to accurately and convincingly convey their involuntary nature to medical students, colleagues, school staff, or even family members who might be unfamiliar with the disorder. It is difficult to find words to clearly and adequately convey the essence of behaviors like those that we find in LND without, in some way, implying intent.
Ultrastructure of rhizoids in the marine bryozoan Dendrobeania fruticosa (Gymnolaemata: Cheilostomata)
Authors: Shunatova Natalia , Denisova Sofia , Shchenkov Sergei 
Published: March 2021

AbstractBryozoans form colonies of iterated modules, termed zooids, and display varying degrees of polymorphism. Polymorphic colonies comprise autozooids (or feeding zooids) and heteromorphic zooids, among which the most common types are avicularia and kenozooids. Kenozooids differ in shape, size, and presumed function. Among this diversity, there are rhizoids, which serve to attach colonies to the substrate or to lift them above it. To date, only general data on anatomy of kenozooids at light microscopy level are available. Here, we present the first description of the ultrastructure of the holdfast‐like rhizoids of the cheilostome bryozoan Dendrobeania fruticosa. The rhizoid wall is composed of a single‐layered epidermis, which produces the ectocyst. The voluminous cavity is acoelomate: it has no special cellular lining, nor any signs of an extracellular matrix toward the epidermis. It is traversed by delicate branching funicular strands that originate from the pore plate. The only cells in contact with the epidermis are the cells of the funicular system and the storage cells. The pore plate between the rhizoid and autozooid includes a variable number of communication pores. Each pore is plugged with a rosette complex, which includes a cincture cell and four special cells extending through the pore. The limiting cells are absent, and the special cells are in direct contact with the funicular strands. Cell contacts between special cells are absent; moreover, there are spaces between their proximal lobes filled with a heterogeneous matrix similar to that in the lumen of the funicular strands. Such matrix is also found outside of the extracellular matrix surrounding the special cells. These findings allow us to suggest that nutrient transport most likely occurs between, rather than through, the special cells. However, further studies are needed to understand how the rosette complex functions.

AbstractPorous polymer materials derived from poly(ethylene glycol dimethacrylate) (poly‐EGDMA) and antibiotic containing polylactide (PLA) are obtained for the first time. Porous poly‐EGDMA monoliths with a system of open interconnected pores are synthesized by a visible light‐induced radical polymerization of EGDMA in the presence of 70 wt% of porogenic agent, e.g., 1‐butanol, 1‐hexanol, 1‐octanol, or cyclohexanol. The porosity of the obtained polymers is 75–78%. A modal pore size depends on the nature of the porogen and varies from 0.5 µm (cyclohexanol) to 12 µm (1‐butanol). The polymer matrix made with 1‐butanol features the presence of pores ranging from 1 to 100 µm. The pore surface of poly‐EGDMA matrices is inlayered with poly‐D,L‐lactide (Mn 23 × 103 Da, PDI 1.31). The PLA‐modified poly‐EGDMA retains a porous structure that is similar to the initial poly‐EGDMA but with improved strength characteristics. The presence of antibiotic containing PLA ensures a high and continuous antibacterial activity of the hybrid polymeric material for 7 days. The nontoxicity of all the porous matrices studied makes them promising for clinical tests as osteoplastic materials.
Cotton as Precursor for the Preparation of Porous Cellulose Adsorbers

Published: March 2021

AbstractNatural biopolymer‐based porous spherical adsorbers from cellulose have good efficiency for removal of metal ion pollutants from aqueous media. However, high purity celluloses, most commonly used as precursors for preparation of the adsorber spheres, require complex synthesis processes, which consume energy and chemicals, and may thus lead to other types of pollution. In this work, the possibility to prepare cellulose‐based porous spherical adsorbers directly from cotton, using an ionic liquid‐based platform is analyzed in detail. The dissolution of microcrystalline cellulose (MCC), as reference, and of cotton in ionic liquid‐based solvents and the properties of the obtained polymer solutions are investigated in order to evaluate their processability toward porous macrospheres using the drop shaping cum non‐solvent induced phase separation process. The properties of the prepared spheres are assessed. The dissolution of cotton is more difficult than the dissolution of MCC and the formed cotton‐based solutions are considerably more viscous, which makes their processability possible only after careful adjustment of the cotton solution concentration. The maximum adsorption capacities toward Cu2+ are ≈110 and ≈72 mg/g for the porous cotton‐based spheres prepared from 1‐ethyl‐3‐methylimidazolium acetate ([Emim][OAc]):dimethylsulfoxide (DMSO) = 2:1 and 1‐butyl‐3‐methylimidazolium acetate ([Bmim][OAc]):DMSO = 2:1 solutions, respectively.

AbstractNovel flexible anisotropic conductive film with light‐controllable property is designed and constructed. The film is composed of electrospun polymeric nanobelts array loaded with TiO2 nanoparticles. The products are characterized by scanning electron microscopy, X‐ray diffractometry, thermal gravimetric analysis, and ultraviolet–visible absorption spectroscopy. The conductivity of the materials along two perpendicular directions of the film surface is investigated under dark and light irradiation conditions. The results reveal that the film is insulative in all directions under dark condition. Under irradiation, the light resistance along the length direction of the nanobelts is three orders of magnitude lower than the dark resistance, and the light resistance along the length direction of the nanobelts is two orders of magnitude lower than that along the perpendicular direction on the film surface. The effects of loading quantity of TiO2 nanoparticles and ratio of polyethylene oxide (PEO) to polymethylmethacrylate (PMMA) on the properties of the products are studied, and the influencing mechanism is proposed. This kind of anisotropic conductive film with new characteristics has broad application prospects in controllable flexible circuits and other fields.
Sponsor message processing in live broadcasts—A pilot study on the role of game outcome uncertainty and emotions
Authors: Breuer Christoph , Rumpf Christopher , Boronczyk Felix 
Published: March 2021

AbstractLive sport broadcasts can evoke emotions in consumers and allow companies to reach their audience in environments that allow for automatic processing of brand messages. However, only few studies have applied psychophysiological methodologies to assess how the live nature of a competition and viewers' emotions affect the processing of sponsor messages, and prior research has mostly relied on ex‐post data. Therefore, to identify the interplay of game outcome uncertainty, viewers' emotions and attention to sponsor messages, this exploratory lab study tracks continuous viewer data during live sport broadcasts. Soccer fans' (n = 11) arousal, emotional valence, and visual attention to sponsors while watching live soccer broadcasts were measured using galvanic skin response, video‐based facial expressions, and infrared eye‐tracking. In‐play betting odds served as an indicator of outcome uncertainty. Multi‐level modeling reveals that greater outcome uncertainty increases arousal and the magnitude of emotional response. Further, the data reveal that low‐to‐moderate arousal and valence‐neutral emotional states increase viewer attention to sponsor messages. This study is the first to consider the dynamics of live sports experiences in the explanation of sponsorship effectiveness. It contributes to the literature by using continuous measurements involving psychophysiological data to investigate emotions and attention to sponsors.
Pain as a significant symptom in patients with periodic paralysis—A cross‐sectional survey
Authors: Giacobbe Alaina , Subramony Sub , Chuquilin Miguel 
Published: March 2021

AbstractIntroductionPeriodic paralysis (PP) is thought to be limited to episodes of muscle weakness, but there are reports of fibromyalgia‐like pain in PP. We aimed to evaluate pain and comorbid sleep, fatigue, and mood disorders in PP patients.MethodsWe administered a cross‐sectional survey to PP patients at the 2019 Periodic Paralysis Conference. The survey consisted of the Brief Pain Inventory, Widespread Pain Index, Pittsburgh Sleep Quality Index, Modified Fatigue Impact Scale, and ten‐question Center for Epidemiologic Studies Depression Scale (CESD‐10). Descriptive statistics for PP patients were calculated and compared with earlier studies.ResultsForty‐four individuals with PP took the survey. Of these patients, 52.3% reported a moderate to severe interference of pain on their lives, and 45.5% met the study criteria for fibromyalgia. Patients with SCN4A mutations had higher rates of fibromyalgia than the next most prevalent gene mutation, CACNA1S. In patients with pain, there were increased rates of comorbid fatigue, depression, and poor sleep quality.DiscussionPain, akin to fibromyalgia, is a significant symptom of PP and can affect quality of life. Pain in PP was more prevalent than in the general population, at a rate comparable with other chronic neuromuscular disease groups. PP patients could benefit from a multidisciplinary approach to assess their pain, sleep, fatigue, and mood.

AbstractAimTo analyse the application status of nursing assessment terminology for neurological conditions and determine whether the International Classification of Functioning, Disability, and Health (ICF) covers nursing assessment.DesignA multi‐centre cross‐sectional study.MethodsFour researchers extracted all nursing problems from the patients of three different hospitals and formed a pool of nursing terminology from the electronic nursing records, self‐reports, family reports, medical examinations, and clinical records for all patients. The ICF Linking Rules were then used to map the nursing assessment terminology of neurological conditions with the ICF.ResultsThough 37.5% of nursing assessment terms were closely related to neurological diseases, this does not appear in the existing electronic nursing assessment records. The unrecorded rate of 9 (16.1%) terms ranged from 40%–50%, while the unrecorded rate of 8 (14.3%) terms was more than 80%. Overall, 96.4% of nursing assessment terms could be described by the corresponding categories of the ICF, with 37 (66.1%) of the “same” concepts, 9 (16.1%) “similar” concepts, 6 (10.7%) “narrower” concepts (the nursing assessment terms were more specific than the ICF categories), and 2 (3.6%) “broader” concepts (the nursing assessment were less specific than the ICF categories).

ObjectivesThe aim of this study was to assess associations between loss of control (LOC) eating and health outcomes among adolescents undergoing metabolic and bariatric surgery.MethodsA total of 234 adolescents were studied before and up to 6 years after surgery in a prospective, observational cohort design. Adolescents provided self‐reports of LOC eating, pain severity, sleep quality, polycystic ovary syndrome, gastroesophageal reflux disease, and medication usage and objective measures of fasting glucose, serum insulin, glycohemoglobin A1c, cholesterol, triglycerides, and blood pressure. χ2 tests, Wilcoxon rank sums, and generalized linear mixed models were used to assess concurrent and prospective associations between LOC eating and health indicators.ResultsLOC eating presented in 32.5% of adolescents before surgery and was positively associated with sleep disturbances and psychiatric medication usage. After surgery, LOC eating presented in 7.9% to 14.6% of participants and was correlated with improved low‐ and high‐density lipoprotein cholesterol levels and greater back pain. LOC eating was inversely associated with low‐density lipoprotein cholesterol at the next consecutive time point.ConclusionsLOC eating was unexpectedly associated with improved low‐ and high‐density lipoprotein cholesterol in adolescents undergoing metabolic and bariatric surgery. Deleterious effects of LOC eating on obesity‐related health conditions, aside from back pain, were not detected. Metabolic and other weight‐independent health benefits of surgery may persist postoperatively despite LOC eating and associated weight regain.

Published: March 2021

ObjectiveExisting screening tools are inadequate in differentiating binge eating from normative overeating in treatment‐seeking individuals with overweight or obesity, as these individuals tend to overendorse loss‐of‐control (LOC; the hallmark characteristic of binge eating) on self‐report measures. In order for treatment centers to efficiently and accurately identify individuals who would benefit from specialized treatment, it is critical to develop effective brief screening tools. This study examined the sensitivity and specificity of a self‐report screener designed to be used by an outpatient treatment center on a large scale.MethodsParticipants were treatment‐seeking individuals (N = 364) with overweight or obesity who were administered the screener and who completed a subsequent interview assessing for LOC and binge eating.ResultsDiscriminant analyses revealed that the screener achieved 77.6% sensitivity and 77.0% specificity in predicting clinician‐assessed LOC and 75.2% sensitivity and 74.1% specificity in predicting “full‐threshold” binge eating (i.e., ≥12 objectively large binge‐eating episodes within the past 3 months). Post hoc analyses indicated that male participants were more likely to be misclassified with the screener.ConclusionsThe self‐report screener demonstrated satisfactory predictive ability, which is notable given the challenges of discriminating between LOC and normative overeating. However, room for improvement remains. In particular, the inclusion of additional screener items that more fully capture the binge‐eating experience in males is warranted.
