Social anxiety in culturally diverse young people: An insight into lived experiences
Authors: Zegrean Tatiana 
Published: October 2024

AbstractObjectivesThere is little research exploring the subthreshold social anxiety (SSA) in culturally diverse young people. This study addresses this gap and provides an insight into the vivid world of this ‘hidden’ population.DesignFour participants from England were interviewed using semi‐structured interviews. Four superordinate themes and their corresponding subordinate themes emerged from the transcripts: Excessive self‐consciousness—The inner critic and Feeling judged by others; Influences of social and cultural norms—The impact of dress‐code rules and The pressure of high expectations; Embracing a false reality—Patterns of avoidance and The public self; and Coping strategies—Breaking the wall of cultural norms, Pushing the bubble out and Know that you are not alone. Due to the vastness of the data, this study presents only the first two superordinate themes and their corresponding subordinate themes.MethodsThe author chose interpretative phenomenological analysis (IPA). This allowed the participants to describe thoroughly their lived experiences and enabled the researcher to adopt a scientific approach.ResultsThe results revealed that the socio‐cultural background of this population played a pivotal role in the prevalence and expression of SSA.ConclusionsThe participants' experiences were significantly influenced by the social and cultural norms of their country of origin as well as the characteristics of modern society in England. The predominant factors were the pressure of high expectations from family and society, transgenerational trauma, socio‐cultural norms, uncertainty about the future and lack of opportunities to secure employment. Future research could examine the socio‐cultural influences shaping contemporary British society and their impact on youth's mental health.
Is the enthusiasm for Drug‐Coated balloon technology justified?
Authors: Basavarajaiah Sandeep , Bhatia Gurbir , Cortese Bernardo , Khialani Bharat 
Published: October 2024

Key points

The usage of drug coated balloon (DCB) is escalating globally, but the data mainly exists for certain lesion and patient subsets; in‐stent restenosis, small vessel disease, high bleeding risk patients and bifurcation lesions.
As of now there is lack of data on the use of DCB in large vessels and we are sceptical whether we can prove superiority over current generation DES especially in large vessels, but we eagerly look forward to the results of upcoming randomized control trials (Selution de novo and Transform II)
The DCB believers and experienced operators have the responsibility to nurture and look after this relatively novel technology so that its future use and reproducibility of the results are consistent across the globe. To facilitate this, we have to abide by the current evidence and work toward generating new evidence to support and carry the technology forward.

AbstractBackgroundHemophilia is a disease characterized by a high risk of bleeding. With advances in treatment, life expectancy and aging‐associated diseases such as coronary artery disease have increased. Our primary objective is to assess for major adverse outcomes, mortality, and length of hospital stay in individuals with hemophilia presenting for acute coronary syndrome (ACS) and undergoing percutaneous coronary intervention (PCI).MethodsOur retrospective cohort study analyzed data from the Nationwide Inpatient Sample Database (NIS) for 2018 to investigate the outcomes of ACS management with PCI in adults with and without hemophilia. We used ICD‐10 codes to exclude patients with significant comorbidities and identify those with ACS undergoing PCI. Propensity score matching and multivariable logistic regression were employed to account for over 20 baseline characteristics, mitigating confounding factors.ResultsThe incidence of gastrointestinal bleeding (11.0% vs. 2.8%, p < 0.001), hemorrhagic stroke (10.0% vs. 1.4%, p < 0.001), and retroperitoneal hemorrhage (5.6% vs. 1.4%, p < 0.001) was significantly higher in individuals with hemophilia undergoing PCI compared to those without hemophilia. Additionally, venous thromboembolism (VTE) incidence was notably higher in the hemophilia cohort (6.6% vs. 2.4%, p = 0.027). The hemophilia cohort also experienced a higher mortality rate (7.1% vs. 3.3%, p = 0.037) and longer hospital stays.ConclusionPatients with hemophilia undergoing PCI are at a significantly greater risk of adverse events, increased mortality, and longer hospital stays than the general population. To mitigate the risk of unfavorable outcomes, it is crucial to ensure adequate replenishment of coagulation factors and establish close collaboration between cardiologists and hematologists.

Published: October 2024

Key Clinical MessageSpontaneous rectus sheath hematoma is a rare complication in chronic liver disease patients. Early clinical suspicion with prompt radiological evaluation is crucial for accurate diagnosis and timely management.AbstractSpontaneous rectus sheath hematoma can present as an acute abdomen in the emergency department. The rupture of the upper and lower epigastric arteries and their branches is the main cause of hematoma formation. Hepatic dysfunction can affect the clotting process, increasing the risk of hematoma development. Computed tomography is the preferred diagnostic tool. Most hematomas can be managed conservatively, with only a few requiring minimal intervention or surgical management. We report an uncommon instance of spontaneous rectus sheath hematoma in a patient with chronic liver disease presenting with painful abdominal distention, mimicking a hernia and initially posing a diagnostic challenge. The rectus sheath hematoma was definitively diagnosed through clinical and radiological evaluation and subsequently evacuated with successful outcomes.

Published: October 2024

Key Clinical MessageBenign ancient retroperitoneal schwannomas (BARS) exhibit abdominal masses and flank pain to incidental findings at more advanced stages. Histopathological and immunohistochemical analysis is essential for confirmation of benign nature. Our patient was misdiagnosed as ureteric colic, highlighting the need to consider BARS in differential diagnosis to prevent complications like hydronephrosis.AbstractAncient schwannomas are usually benign neoplasms that originate from Schwann cells of peripheral nerves. We present a novel case of a 24‐year‐old young male with left flank pain and nausea which was initially thought to be left ureteric colic. However, in‐depth imaging and biopsy revealed a retroperitoneal mass. The definitive diagnosis was narrowed down to Benign Retroperitoneal Ancient Schwannoma (BARS) via immunohistochemistry and histopathological analysis. This often marble‐shaped S100 protein‐positive tumor is an under‐recognized and potential cause of hydronephrosis if localized near the renal structures. In addition, the retroperitoneal location with infrarenal abdominal aortic adherence is another rare peculiarity in the present case that demands prompt diagnosis and surgical excision to avoid any cardiovascular sequelae such as hypotension and abdominal pain, as indicated by the natural history of growth of this benign tumor. Therefore, timely excision of this benign tumor prior to its further proliferation is paramount. We initially planned laparoscopic removal but adopted excision via laparotomy because of the proximity of the vital structures. The postoperative course of the patient was uneventful and subsequently the patient's presenting complaint of left abdominal flank pain greatly improved. The patient was advised to undergo follow‐up computed tomography scan of kidney ureter bladder and RFT evaluation 6 months postsurgery which indicated no evidence of recurrence or iatrogenic complications. The diagnosis and management of the present case share valuable experiences for similar future cases worldwide.

Published: October 2024

AbstractCatalytic hydrogenation is one of the most important transformations in both academia and industry. Compared with direct hydrogenation with molecular hydrogen or transfer hydrogenations with hydrides, electrohydrogenation provides an alternative and practical pathway using proton as the hydrogen source. In this review, we have summarized the recent advances in electrohydrogenations of polar and non‐polar unsaturated compounds catalyzed by earth‐aubundant metal complexes. In addition, we also present a detailed discussion of the scope and limitations, plausible mechanisms and the opportunities for further development.

Published: October 2024

AbstractBicontinuous cubic liquid crystalline (LC) phases are of particular interest due their possible applications in electronic devices and special supramolecular chirality. Herein, we report the design and synthesis of first examples of achiral bent‐shaped polycatenar dimers, capable of displaying mirror symmetry breaking in their cubic and isotropic liquid phases. The molecules have a taper‐shaped 3,4,5‐trialkoxybenzoate segment connected to rod‐like building unit terminated with one terminal flexible chain. The two segments were connected using an aliphatic spacer with seven methylene units to induce bending of the whole structure. Investigated by the small‐angle X‐ray scattering (SAXS), a double network achiral cubic phase Cub/Ia
d, which is a meso‐structure, and a chiral triple network cubic phase Cub/I23[*] are formed. The molecules self‐assemble into molecular helices and progress along the networks. Interestingly, different linking groups such as ester or azo linkages and core fluorination lead to distinct local helicity, resulting in an alkyl chain volume dependent phase transition sequence Ia
d(L) ‐ I23* ‐ Ia
d(S). The re‐entry of Ia
d phase and loss of supramolecular chirality is attributed to the delicate influence of steric effect at the mono‐substitute end and interhelix interaction. Besides, aromatic core fluorination was proved to be a successful tool stabilizing the cubic phases in these dimers.
Potassium sulphate production from an aqueous sodium sulphate from lead‐acid battery recycling: Impact of feedstock impurities on products yields

Published: October 2024

AbstractThe increasing demand for renewable energy highlights the need for efficient energy storage solutions. Despite various available technologies, lead‐acid batteries remain preferred for many industrial applications due to their inherent advantages. However, their expanded use necessitates proper waste management and recycling practices. During lead‐acid battery recycling, Na₂SO₄ is generated as a waste product, which cannot be directly sold due to quality concerns and limited market demand. Consequently, advanced waste management techniques are required to comply with government regulations on industrial waste disposal. Despite these challenges, Na2SO4 serves as a vital precursor for producing K2SO4, a valuable fertilizer. Prior research on the glaserite process for converting Na2SO4 to K2SO4 has assumed Na2SO4 to be pure—without traces of impurities. However, Na2SO4 recovered from battery recycling contains various contaminants. To address this, HSC Chemistry software was used to model K2SO4 and NaCl production from impure Na2SO4 and KCl, considering feed impurities. Under ideal conditions—a 1 bar pressure, 25°C feed temperature, and 40°C reactor temperature—over 90% yield of K2SO4 and NaCl was achieved in the absence of impurities. However, the addition of impurities resulted in a reduction in yields. Notably, impurity levels ranging from 1% to 4% by weight still allowed for yields exceeding 90%. Furthermore, a review of reactor compositions revealed a significant depletion of potassium and chlorine ions which are crucial for K2SO4 and NaCl production as impurity levels varied from 0% to 10%. These findings emphasize the negative impact of impurities on K2SO4 and NaCl yields.

ABSTRACTBackgroundPostoperative atrial fibrillation (POAF) is a common complication after coronary artery bypass grafting (CABG) that prolongs hospitalization and increases expenses.HypothesisPerioperative risk factors may predict POAF.MethodsFrom March 2015 to January 2023, 6229 patients who underwent isolated CABG and were in sinus rhythm before CABG were included in this retrospective study. The preoperative and postoperative variants of patients were collected and analyzed by univariate analyses between the patients with and without POAF. Multivariate logistic regression analysis was then used to study the independent risk factors for POAF.ResultsThe incidence of POAF in this group of patients was 30.94%. Univariate analyses demonstrated that age (p < 0.001), hypertension (p < 0.001), smoking (p < 0.05), cardiopulmonary bypass (CPB) time (p < 0.01), and ejection fraction (EF, p < 0.01) were the risk factors for POAF. Multivariate logistic regression analysis determined the independent risk factors associated with POAF were old age (odds ratio [OR] = 1.062, p = 0.000) and low EF (OR = 0.980; p = 0.008).ConclusionsIn the current era, after isolated CABG surgery, there is still a quite high incidence of POAF (30.94% in this group of CABG patients). The main risk factors correlating to POAF include age, hypertension, smoking, CPB time, and EF. Among these factors, multivariate analysis identified old age and low EF as the independent risk factors associated with POAF. Particular care should be taken in the perioperative period for these patients in the prevention of POAF.

AbstractPotential applications of known compounds from the V2O‐Y2O3 system, i. e. YVO4, Y8V2O17 and Y10V2O20, were the inspiration to undertake research, the main goal of which was to determine whether unknown phases of the solid solution type are formed in this system. Solid solutions are still sought‐after phases because their properties depend on their chemical composition. In this work it was experimentally demonstrated that a new substitute solid solution with the formula Y2‐xVxO3+x (0.00<×<0.60) is formed from mixtures of V2O5 with Y2O3 as a result of mechanochemical synthesis. Its properties were examined by using, i.a. XRD (X‐ray diffraction) and UV‐Vis‐DRS (ultraviolet‐visible light spectroscopy with diffusion reflectance) methods. It was found among other things, that it crystallizes in a regular system, exhibits a Y2O3 structure and is thermally stable up to at least 800 °C (for x=0.40). Moreover, the estimated value of the band gap width indicated that the solid solution Y2‐xVxO3+x belongs to the class of semiconductors. The study of dielectric properties of new phase was performed by means of broadband dielectric spectroscopy. The obtained measurement data showed the presence of relaxation type dielectric mechanisms. The thermally activation energies of the relaxation processes related to the electric conductivity were calculated.

ABSTRACTBackgroundBreast cancer is the leading cause of cancer‐related deaths in the female population. Axillary lymph nodes (ALN) are a group of the most common metastatic sites of breast cancer. Timely assessment of ALN status is of paramount clinical importance for medical decision making.AimsTo utilize contrast‐enhanced ultrasound (CEUS)‐based radiomics models for noninvasive pretreatment prediction of ALN status.Methods and ResultsClinical data and pretreatment CEUS images of primary breast tumors were retrospectively studied to build radiomics signatures for pretreatment prediction of nodal status between May 2015 and July 2021. The cases were divided into the training cohorts and test cohorts in a 9:1 ratio. The mRMR approach and stepwise forward logistic regression technique were used for feature selection, followed by the multivariate logistic regression technique for building radiomics signatures in the training cohort. The confusion matrix and receiver operating characteristic (ROC) analysis were used for accessing the prediction efficacy of the radiomics models. The radiomics models, which consist of six features, achieved predictive accuracy with the area under the ROC curve (AUC) of 0.713 in the test set for predicting lymph node metastasis.ConclusionThe CEUS‐based radiomics is promising to be developed as a reliable noninvasive tool for predicting ALN status.

Published: October 2024

AbstractMouse models remain at the forefront of immuno‐oncology research, providing invaluable insights into the complex interactions between the immune system and developing tumors. While several flow cytometry panels have been developed to study cancer immunity in mice, most are limited in their capacity to address the complexity of anti‐cancer immune responses. For example, many of the panels developed to date focus on a restricted number of leukocyte populations (T cells or antigen‐presenting cells), failing to include the multitude of other subsets that participate in anti‐cancer immunity. In addition, these panels were developed using blood or splenic leukocytes. While the immune composition of the blood or spleen can provide information on systemic immune responses to cancer, it is in the tumor microenvironment (TME) that local immunity takes place. Therefore, we optimized this spectral flow cytometry panel to identify the chief cell types that take part in cancer immunity using immune cells from cancer tissue. We used pancreatic tumors implanted both orthotopically and subcutaneously to demonstrate the panel's flexibility and suitability in diverse mouse models. The panel was also validated in peripheral immune districts (the blood, spleen, and liver of tumor‐bearing mice) to allow comparisons between local and systemic anti‐tumor immunity. © 2024 The Author(s).

AbstractThis work studies the use of epoxy and polyurethane formulations as binders for the aqueous processing of activated carbon (AC) electrodes used as positive and negative electrodes in Electrochemical Double Layer Capacitors (EDLCs). The use of amine and carbodiimide as crosslinkers is also evaluated. The mechanical properties of those different binders have been investigated, looking towards aqueous processable and flexible electrodes. Microstructural analysis of the fabricated AC electrodes has been carried out to understand the pore‐blocking effect exhibited by certain polymers. Furthermore, electrochemical characterization of all the systems has been performed by cyclic voltammetry, electrochemical impedance spectroscopy, and constant current charge/discharge measurements at different current densities. The obtained results show that polyurethane (PU) outperforms in terms of energy and power density the carboxymethyl cellulose:styrene butadiene rubber (CMC : SBR) reference system. Moreover, the studied polyurethanes maintain close to 100 % of their initial capacitance after 2500 cycles under a current density of 5 A g−1 and a discharge time of 20 s.

AbstractThe key aspect of the photoelectrochemical CO2 reduction reaction (PEC CO2 RR) lies in designing cathode materials that can generate high‐energy photoelectrons, enabling the activation and conversion of CO2 into high‐value products. In this study, a coaxially wrapped ZnO@ZnSe array heterostructure was synthesized using a simple anion exchange strategy and metallic Bi nanoparticles (NPs) were subsequently deposited on the surface to construct a Bi/ZnO@ZnSe photocathode with high CO2 conversion capability. This array photocathode possesses a large aspect ratio, which simultaneously satisfies a low charge carrier migration path and a large specific surface area that facilitates mass transfer. Additionally, the barrier formed at the n‐n heterojunction interface hinders the transfer of high‐energy photoelectrons from ZnSe to lower energy levels, resulting in their rapid capture by Bi while maintaining a relatively long lifetime. These captured electrons act as active sites, efficiently converting CO2 into CO with a Faradaic efficiency above 88.9 % at −0.9 V vs. RHE and demonstrating superior stability. This work provides a novel approach for synthesizing high‐energy photoelectrode materials with long lifetimes.

Published: October 2024

AbstractLi‐O2 batteries (LOBs) have garnered significant attention in recent years due to high theoretical specific capacity, however, the sluggish charge‐discharge reaction kinetics and rapid failure under high current densities have hindered their further application. This work presents a photo‐responsive catalyst (UIO‐66‐NH2) supported on carbon cloth, which could enhance the reaction kinetics of LOBs and improve the discharge capacity under high current densities. It demonstrates that under light, the overpotential decreases by 0.9 V, and the discharge capacity reaches an impressive 4.8 mAh cm−2 at a current density of 0.5 mA cm−2. This finding is expected to inspire the development of various novel MOF‐based photoelectrodes for LOBs.
