AbstractCoronary artery disease (CAD) and its complications remain the main cause of morbidity and mortality worldwide. Patients with extensive CAD and multiple comorbidities who require complex, high‐risk percutaneous coronary intervention (HR‐PCI) are at risk of haemodynamic instability and may require short‐term mechanical circulatory support (MCS) during the procedure to maintain sufficient perfusion and prevent ischaemia. Impella is a microaxial continuous blood flow pump used for percutaneous support of the left ventricle in patients undergoing HR‐PCI. Data from randomized controlled trials and registries suggested an advantage for Impella devices in patients undergoing HR‐PCI, compared with other types of MCS. As a thorough understanding of the benefits and drawbacks of the Impella technology is crucial for patient outcomes, we provide a technological overview of Impella and share our experiences gathered during the implementation of institutional Impella programmes in Poland as a roadmap of selection and periprocedural care for patients treated with Impella in the setting of HR‐PCI. We propose 10 steps for implementation of an institutional Impella programme for HR‐PCI, including (i) dedicated staff training; (ii) standard operating procedure and troubleshooting algorithms prior to the first intervention; (iii) patient selection by the multidisciplinary Heart Team; (iv) patient preparation using multimodality imaging; (v) procedure planning in terms of large‐bore access, equipment, and complete revascularization; (vi) starting with HR‐PCI support; (vii) starting with femoral artery access in a patient without extensive peripheral artery disease; (viii) multidisciplinary care after the procedure; (ix) haemodynamic and laboratory monitoring to ensure immediate diagnosis of access‐site complications, bleeding, haemolysis, acute kidney injury, and infections; and (x) careful revision of every HR‐PCI case with the team.

Published: June 2023

AbstractA visible light mediated protocol for the synthesis of polyhalogenated and deuterated δ‐ and γ‐lactams from readily available alkyl halides is reported. The reaction involves the generation of haloalkyl radicals through halogen atom transfer (XAT) and subsequent arylalkylation of olefins to afford dihydroisoquinolinones and oxindoles. This new XAT protocol exhibits wide scope under mild conditions and enables access to new halogenated chemical space.
Barriers and drivers to increasing sustainable bivalve seafood consumption in a mass market economy

Published: June 2023

AbstractBivalve mollusc meat—that from mussels, clams, and oysters—offers a highly sustainable and nutritious alternative to meat from other shellfish, fish, or livestock. However, bivalves are an unpopular mass market food relative to these other meat items, limiting our ability to reap potential environmental and health benefits. Hence, this study aimed to assess current barriers to and drivers for bivalve consumption and investigated whether offering bivalves in a highly transformed (i.e., more processed) product format might help to drive consumption. The United Kingdom was used as a case study, and the study was performed via an online survey. Nutrition and quality of ingredients were key drivers, and price and convenience key barriers to bivalve consumption, with views on taste/smell/texture mixed. The more regularly individuals consumed meat, the more willing they were to try bivalves, and those who thought bivalves were healthier or more environmentally friendly than livestock were more likely to substitute bivalves for meat. Importantly, individuals were more willing to substitute highly transformed than minimally transformed (i.e., unprocessed) meats for bivalves. They were also willing to pay more for highly transformed bivalves than any other highly transformed meat product. We suggest that greater publicity regarding the health and environmental benefits of bivalve meat, and industry engagement to develop and pilot a greater range of appealing, affordable, and convenient bivalve products, are key actions that can help drive growth in the bivalve sector for planetary benefit.

Published: June 2023

AbstractThis study examines the impact of crude oil volatility jumps on the realized volatility (RV) of green and dirty stocks in India. In doing so, we first estimate the time‐varying jumps in oil market implied volatility index (OVX) and then augment the heterogeneous autoregressive (HAR) process with the information on such jumps. Our sample runs from December 2012 to April 2022, which includes 2328 data points. Comparing a range of HAR‐type models, we find that crude oil volatility jumps provide additional information, which is not contained even in the OVX index itself. In particular, the HAR–RV model that considers both leverage effects and the information on volatility jumps produces superior forecasts compared with the existing approaches. The economic significance of these results is also supported by a simple value‐at‐risk analysis.

Published: June 2023

AbstractElectric micromobility (e‐micromobility) offers the potential to enhance the sustainability of first‐ and last‐mile journeys in urban areas by reducing the number of private vehicle trips. As a new mode of transport, it is imperative that it is not subject to the same male bias that has been evidenced across our existing transport networks. An in‐depth qualitative study was conducted with 24 UK participants (12 females) to assess the gender factors that relate to the incentives and barriers of e‐micromobility (electric bike and electric scooter) use. Focus groups and interviews were conducted and the data analysis was disaggregated by gender to reveal the differences and similarities between female and male perspectives on e‐micromobility use. Differences in the types of trips made and perceptions of fear were prevalent. Key gender‐related findings and recommendations are made. By reviewing, and acting upon, the different perspectives that males and females have towards e‐micromobility they can be made more inclusive for all. This can enhance their uptake and reduce the dependence on private vehicles.

AbstractBackground and AimsSouth Asian countries, including Pakistan, Afghanistan, India, and Bangladesh, have a high prevalence of pulmonary and extra‐pulmonary tuberculosis (EPTB). This prevalence is influenced by various risk factors such as ethnicity, nutrition, socioeconomic disparities, high out‐of‐pocket healthcare expenses, and specific Mycobacterium Tuberculosis (TB) lineages. The COVID‐19 pandemic has likely hindered access to healthcare and led to under‐reporting of EPTB cases nationally and internationally. This rapid review aimed to summarize the literature on the prevalence and disease outcomes of EPTB in the mentioned countries, compare the situations across countries, and provide recommendations for future action.MethodsThe review utilized PubMed and Google Scholar databases to search for literature on EPTB in South Asian countries. The search string included keywords related to different forms of EPTB and the countries of interest while excluding pulmonary tuberculosis.ResultsThe results showed that both TB, including drug‐resistant TB, and EPTB are prevalent and burdensome in South Asia. In Pakistan, pleural TB was the most commonly reported form of EPTB, followed by lymph node TB, abdominal TB, osteoarticular TB, Central Nervous System TB, and miliary TB. In India, lymph node TB(LNTB) was more common among EPTB cases. Bangladesh reported a high prevalence of EPTB involving lymph node, pleura, and abdomen, while Afghanistan had a higher prevalence of forms such as LNTB and tuberculous meningitis.ConclusionIn conclusion, the prevalence of EPTB in Pakistan, Afghanistan, India, and Bangladesh is alarmingly high and negatively impacts population health. Effective measures are needed for treatment and management of this condition, along with addressing current and future challenges. Strengthening the evidence base through surveillance and research is crucial to understand the patterns and significant factors related to EPTB, requiring investment in these areas.

AbstractPurposeThis study aims to investigate the goal selection patterns among adolescents and examines the extent to which goals focused on oneself, relationships, and the larger community were associated with variability of daily purpose and mean level sense of purpose in life.MethodsParticipants were 213 high school students with an average age of 15.18 years in an urban public school district in the Northeast United States. Students were asked to select their three most important goals one time and report on their sense of purpose once a day for 3 weeks in spring of 2022. Latent class analysis was used to classify students by the type of goals selected. Differences in the overall sense of purpose and its subscales by class were examined.ResultsA model with four classes (Self and Inner Circle, Inner Circle, Other‐Oriented, and Self‐Oriented) best fits the data. There were no statistical group differences in the variability of daily purpose and overall sense of purpose. Only one pairwise comparison was significant and indicated that students in the Other‐Oriented group perceived their purpose as more meaningful than students in the Self and Inner Circle group.ConclusionsFindings from this study provide a lens into goal prioritization patterns among adolescents. Further, although students who were more likely to select other‐oriented goals had somewhat higher perceptions of sense of purpose, findings support the concept of equifinality by suggesting that a sense of purpose may be actualized through a diverse set of specific goals.

AbstractObjectiveRetention is challenging in clinical research with pediatric populations. The retention obstacles that are experienced in adult samples are compounded because child samples depend on caregiver support and engagement. The present paper describes retention improvements following protocol adaptations across a pair of cognitive behavioral pilot studies for nightmare sufferers aged 6–17.MethodsStudy 1 (N = 20) focused retention efforts on rapport and engagement, flexible scheduling, treatment location choice, and incentives. Study 2 (N = 31) sought to increase retention by improving continuity of care, increasing scheduling flexibility, reducing participant time and effort, and increasing choice and attractiveness of incentives.ResultsOnly 13 participants (65%) were retained in Study 1; n = 6 (54.5%) treatment and n = 7 (77.78%) waitlist. In contrast, 29 participants (93.5%) were retained in Study 2; n = 15 (93.8%) treatment and n = 14 (93.3%) waitlist.ConclusionWe conclude that asking for and responding to patient feedback to assess all perceived barriers and burdens for participants is essential to ensure that benefits exceed effort. Allowing choices in size and frequency of incentives, as well as improving continuity of care, and reducing session length even while increasing number of sessions, were noted improvements in Study 2.

AbstractKnowledge of the nonhuman primate morphology and anatomy related to craniofacial mechanoreception is essential for a fundamental understanding of the incidents that have occurred during the evolution of craniofacial features. The present study focuses on the variability in the number of infraorbital foramina and associated anatomical structures such as the infraorbital canal (IOC) and the infraorbital groove (IOG), as they are considered to play an important role in the behavioral ecology of these animals. A total of 19 skulls of Chlorocebus aethiops were analyzed. The number of infraorbital foramina was assessed macroscopically using a magnifying glass and a small diameter probe. Three dimensional (3D) projections and morphometric analysis of the infraorbital foramina, IOCs, and IOGs were performed using microcomputed tomography (micro‐CT) for two skulls that represent one of the most common morphological types. Regardless of sex and body side, the most common morphological type observed in the studied species is the presence of three infraorbital foramina. The IOC takes a funnel or pinched shape. 3D projections were made to assess the course of the infraorbital vascular and nerve bundles in selected individuals. The results indicate a high morphological diversity within the species, although there appears to be a consistent distribution pattern of infraorbital neurovascular bundles in species of the Cercopithecidae family. The use of X‐ray micro‐CT allowed 3D visualization of the maxillary region to determine the variability of the infraorbital foramina and to track the division of the infraorbital neurovascular bundle in the case of the most common macroscopic expression of the number of the infraorbital foramen in C. aethiops, as well as the morphometric of the IOCs and IOGs which are related to mechanoreception of the primate's snout.

Published: June 2023

AbstractDark excitons are fascinating for condensed matter physics, quantum information processing, and optoelectronics due to their long lifetimes. However, direct optical access to dark excitons is still challenging due to the violation of the spin selection rule. Here, a new scheme for the brightening of spin‐forbidden dark exciton in WS2 monolayers by creating artificial out‐of‐plane shear strain that induces an effective in‐plane pseudo‐magnetic field is proposed. To reveal dark excitons, low‐temperature magneto‐photoluminescence experiments on the strained WS2 monolayers are performed. It is found that the dark excitons appear at 59 meV below the bright ones and exhibit an asymmetric magnetic field dependence, which is in agreement with the model taking into account the effect of the out‐of‐plane shear strain on spin‐flip processes of exciton states. The fieldless scheme has great potential in the application of dark excitons for new quantum information processing devices.

Published: June 2023

AbstractQuasi‐2D Dion‐Jacobson (DJ) perovskites are promising candidates for fabricating high‐performance blue‐emitting perovskite light‐emitting diodes (PeLEDs) because of their strong quantum/dielectric confinement and high stability. However, obtaining high‐efficiency blue PeLEDs based on DJ perovskites remains a major challenge. Herein, sky‐blue DJ perovskites are synthesized by using 1,8‐diamino‐3,6‐dioxaoctane as an organic diamine and high‐quality perovskite films are prepared by incorporating poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) as an additive, aiming to improve the photoluminescence quantum yield and electron carrier mobility of the film used as an emissive layer in PeLEDs. Finally, sky‐blue PeLEDs using PVDF‐HFP‐modified DJ perovskite films are demonstrated to show a high maximum external quantum efficiency of 16.55%. A promising strategy is provided to design high‐quality perovskite films for constructing high‐performance blue PeLEDs.
The seller's status‐signaling fallacy
Authors: Moyal Adiel , Garcia Stephen M. 
Published: June 2023

AbstractThe present research introduces the seller's status‐signaling fallacy: Sellers tend to use status signals to attract buyers, but buyers actually prefer sellers who do not signal status. Across six studies we demonstrate the effect using different operationalizations of status and various products for sale. Study 1 demonstrates this effect in contexts where sellers and buyers make initial sales connections. Study 2 replicates the effect in transaction situations where the buyer actually chooses the seller from whom to buy. Studies 3a and 3b reveal a novel mediation model according to which the seller's status signaling is perceived by buyers as an unsuccessful impression management attempt, which ultimately leads those buyers to prefer sellers who do not try to impress them through status signaling. Finally, studies 4a and 4b demonstrate the robustness of the effect in an incentivized setting and explore boundary conditions. This work enriches the growing literature on status signals in two ways. First, it shows that sellers mistakenly believe that such signaling is beneficial for them. Second, contrary to accepted wisdom, it shows that such signaling repels buyers. In the gig‐economy era, where everyone can become a seller in the marketplace, these findings are highly applicable.

AbstractRegeneration is a complex process affected by many elements independent or combined, including inflammation, proliferation, and tissue remodeling. Stem cells is a class of primitive cells with the potentiality of differentiation, regenerate with self‐replication, multidirectional differentiation, and immunomodulatory functions. Stem cells and their cytokines not only inextricably linked to the regeneration of ectodermal and skin tissues, but also can be used for the treatment of a variety of chronic wounds. Stem cells can produce exosomes in a paracrine manner. Stem cell exosomes play an important role in tissue regeneration, repair, and accelerated wound healing, the biological properties of which are similar with stem cells, while stem cell exosomes are safer and more effective. Skin and bone tissues are critical organs in the body, which are essential for sustaining life activities. The weak repairing ability leads a pronounced impact on the quality of life of patients, which could be alleviated by stem cell exosomes treatment. However, there are obstacles that stem cells and stem cells exosomes trough skin for improved bioavailability. This paper summarizes the applications and mechanisms of stem cells and stem cells exosomes for skin and bone healing. We also propose new ways of utilizing stem cells and their exosomes through different nanoformulations, liposomes and nanoliposomes, polymer micelles, microspheres, hydrogels, and scaffold microneedles, to improve their use in tissue healing and regeneration.
