Art of Spiritual Care.
Authors: Boelsbjerg Hanne Bess , Leget Carlo 
Published: June 2023

The article defends the position that providing spiritual care first and foremost is an art in which tools and instruments are subordinate to practical knowledge, experience, and wisdom of the phenomenon.
A growing number of instruments and tools for spiritual care have been developed, tested, and validated. Some have been designed for the purpose of doing research, others have been developed for the practice of spiritual caregiving. These instruments and tools have impact both on the way we provide spiritual care, and the way we look upon spiritual care. Behind these developments are different views about what counts as scientific knowledge, as the methodologies used are based in such different paradigms as natural sciences, social constructivism, and phenomenology. The methodology used impacts how spirituality and spiritual care are viewed, as a methodology shapes our understanding of the object which is studied.
When viewing spiritual care as an art, we base this on an understanding of spiritual care as a dynamic and relational phenomenon. To support this perception, the article structures its arguments on the following elements:
1) The hermeneutic nature of spiritual caregiving 2) The role of the practice of spiritual caregiving 3) The nature of tacit and intuitive knowledge. The article bridges these arguments by providing empirical examples from spiritual care providers in Denmark.

AbstractThe lithium‐metal anode is a promising candidate for realizing high‐energy‐density batteries owing to its high capacity and low potential. However, several rate‐limiting kinetic obstacles, such as the desolvation of Li+ solvation structure to liberate Li+, Li0 nucleation, and atom diffusion, cause heterogeneous spatial Li‐ion distribution and fractal plating morphology with dendrite formation, leading to low Coulombic efficiency and depressive electrochemical stability. Herein, differing from pore sieving effect or electrolyte engineering, atomic iron anchors to cation vacancy‐rich Co1−xS embedded in 3D porous carbon (SAFe/CVRCS@3DPC) is proposed and demonstrated as catalytic kinetic promoters. Numerous free Li ions are electrocatalytically dissociated from the Li+ solvation complex structure for uniform lateral diffusion by reducing desolvation and diffusion barriers via SAFe/CVRCS@3DPC, realizing smooth dendrite‐free Li morphologies, as comprehensively understood by combined in situ/ex situ characterizations. Encouraged by SAFe/CVRCS@3DPC catalytic promotor, the modified Li‐metal anodes achieve smooth plating with a long lifespan (1600 h) and high Coulombic efficiency without any dendrite formation. Paired with the LiFePO4 cathode, the full cell (10.7 mg cm−2) stabilizes a capacity retention of 90.3% after 300 cycles at 0.5 C, signifying the feasibility of using interfacial catalysts for modulating Li behaviors toward practical applications.

AbstractEngineered skin substitutes derived from human skin significantly reduce inflammatory reactions mediated by foreign/artificial materials and are consequently easier to use for clinical application. Type I collagen is a main component of the extracellular matrix during wound healing and has excellent biocompatibility, and platelet‐rich plasma can be used as the initiator of the healing cascade. Adipose mesenchymal stem cell derived exosomes are crucial for tissue repair and play key roles in enhancing cell regeneration, promoting angiogenesis, regulating inflammation, and remodeling extracellular matrix. Herein, Type I collagen and platelet‐rich plasma, which provide natural supports for keratinocyte and fibroblast adhesion, migration, and proliferation, are mixed to form a stable 3D scaffold. Adipose mesenchymal stem cell derived exosomes are added to the scaffold to improve the performance of the engineered skin. The physicochemical properties of this cellular scaffold are analyzed, and the repair effect is evaluated in a full‐thickness skin defect mouse model. The cellular scaffold reduces the level of inflammation and promotes cell proliferation and angiogenesis to accelerate wound healing. Proteomic analysis shows that exosomes exhibit excellent anti‐inflammatory and proangiogenic effects in collagen/platelet‐rich plasma scaffolds. The proposed method provides a new therapeutic strategy and theoretical basis for tissue regeneration and wound repair.
Dual Nickel/Photoredox‐Catalyzed Synthesis of N‐formyl N,N’‐Diaryl Ethylenediamines via Multiple C−N/C−C Coupling of Nitroarenes with Trimethylamine
Authors: Zheng Tongtong , Feng Zhe , Ma Jun‐An , Cheung Chi Wai 
Published: June 2023

AbstractN,N’‐Diaryl ethylenediamines are common feedstocks in organic synthesis and important structural motifs in medicinal chemistry. Whereas the C−N formation reactions based on anilines and aryl halides are the most direct methods to access N,N’‐diaryl ethylenediamines, the photocatalytic synthetic version remains undeveloped. Herein we describe the dual nickel/photoredox‐catalyzed amination reaction using nitroarenes and trimethylamine as reaction substrates. This cascade transformation hinges on the multiple C−N and C−C coupling events based on the nitrogen radical and α‐aminomethyl radical derived from nitroarene and trimethylamine, respectively. A variety of N‐formyl N,N’‐diaryl ethylenediamines can be obtained under the reaction protocol. Subsequent hydrolysis offers the N,N’‐diaryl ethylenediamines for further derivatizations.

Published: June 2023

AbstractAlterations of the glycosylation machinery are common events in cancer, leading to the synthesis of aberrant glycan structures by tumor cells. Extracellular vesicles (EVs) play a modulatory role in cancer communication and progression, and interestingly, several tumor‐associated glycans have already been identified in cancer EVs. Nevertheless, the impact of 3D tumor architecture in the selective packaging of cellular glycans into EVs has never been addressed. In this work, the capacity of gastric cancer cell lines with differential glycosylation is evaluated in producing and releasing EVs when cultured under conventional 2D monolayer or in 3D culture conditions. Furthermore, the proteomic content is identified and specific glycans are studied in the EVs produced by these cells, upon differential spatial organization. Here, it is observed that although the proteome of the analyzed EVs is mostly conserved, an EV differential packaging of specific proteins and glycans is found. In addition, protein–protein interaction and pathway analysis reveal individual signatures on the EVs released by 2D‐ and 3D‐cultured cells, suggesting distinct biological functions. These protein signatures also show a correlation with clinical data. Overall, this data highlight the importance of tumor cellular architecture when assessing the cancer‐EV cargo and its biological role.

AbstractAcute coronary syndrome (ACS), comprising unstable angina (UA) and acute myocardial infarction (AMI), is the leading cause of death worldwide. Currently, lacking effective strategies for classifying ACS hinders the prognosis improvement of ACS patients. Disclosing the nature of metabolic disorders holds the potential to reflect disease progress and high‐throughput mass spectrometry‐based metabolic analysis is a promising tool for large‐scale screening. Herein, a hollow crystallization COF capsuled MOF hybrids (UiO‐66@HCOF) assisted serum metabolic analysis is developed for the early diagnosis and risk stratification of ACS. UiO‐66@HCOF exhibits unrivaled chemical and structural stability as well as endowing satisfying desorption/ionization efficiency in the detection of metabolites. Paired with machine learning algorithms, early diagnosis of ACS is achieved with the area under the curve (AUC) value of 0.945 for validation sets. Besides, a comprehensive ACS risk stratification method is established, and the AUC value for the discrimination of ACS from healthy controls, and AMI from UA are 0.890, and 0.928. Moreover, the AUC value of the subtyping of AMI is 0.964. Finally, the potential biomarkers exhibit high sensitivity and specificity. This study makes metabolic molecular diagnosis a reality and provided new insight into the progress of ACS.

Published: June 2023

AbstractObjectivesTestosterone concentrations in men decline with advancing age. However, the cause of the decline is yet to be fully elucidated. Therefore, the aims of this study were to examine the associations between chronic diseases such as obesity and type 2 diabetes mellitus (T2DM) with total testosterone (TT) and sex hormone‐binding globulin (SHBG), using a large nationally‐representative data set (National Health and Nutrition Examination Survey; NHANES).MethodsNHANES is a cross‐sectional survey, physical examination, and laboratory evaluation of a nationally‐representative sample of a non‐institutionalized United States population. Male participants aged ≥18 years during the NHANES 2013–2014 and NHANES 2015–2016 survey periods were selected for this analysis. The analysis included the following data: body mass index (BMI), oral glucose tolerance test (OGTT), homeostatic model assessment of insulin resistance (HOMA‐IR), insulin, glucose, and age.ResultsAn overweight or obese condition was significantly inversely associated with TT and SHBG, even after adjusting for other variables. Several variables associated with T2DM (OGTT, HOMA‐IR, insulin, and glucose) were also inversely associated with TT; however, only the associations between OGTT and insulin with TT remained significant after adjusting for the other variables. Insulin and HOMA‐IR levels were significantly inversely associated with SHBG; however, only the association between SHBG and pre‐diabetic HOMA‐IR levels remained significant after adjusting for the other variables. OGTT became significantly associated with SHBG after adjusting for the other variables. Age was significantly inversely associated with TT, but positively associated with SHBG, even after adjusting for other variables.ConclusionThe results of the present study, which is the largest to date, indicate that a marker of obesity, BMI, and some markers of T2DM are both independently and significantly inversely associated with TT and SHBG.

Published: June 2023

AbstractNatural products isolation studies were performed on two Dodonaea species. This led to the discovery of one previously unreported prenylated flavonoid bearing a malonic acid moiety and six known compounds from the aerial parts of Dodonaea filiformis. In addition, three previously unreported natural products (another malonic‐acid‐containing prenylated flavonoid, a prenylated flavonoid and an ent‐labdane diterpenoid) and seven known compounds were found from the flowers of D. viscosa. Furthermore, as a result of this work, a revised structure is proposed for a prenylated flavonoid previously isolated from D. viscosa.

Published: June 2023

AbstractIn this study, three kinds of newly flexible positive temperature coefficient (PTC) materials are fabricated by a simple preparation method. Due to introducing the hybrid filler of carbon nanotube and carbon black, these materials exhibit remarkable PTC effect including the PTC intensity of more than four‐orders magnitude and the resistivity‐temperature coefficient of 154%/°C. The Curie points of PTC materials are regulated to room‐temperature range by the low melting phase and influenced by melting onset temperatures of their solid–liquid phase change. With the help of transmission electron microscope, the micro‐capsule structure of the phase change regions is observed, and the hybrid conductive fillers randomly distribute in the blend matrix to construct three‐dimensional conductive network. Using the PTC materials as a heating element, the equilibrium temperature of the controlled device can be maintained around their Curie point without any control method. Moreover, the adaptive thermal control effect becomes more obvious with the increase of ambient temperature and initial heating power. Furthermore, the thermal control accuracy fluctuates within 0.15°C without any external control method, and is improved to round 0.08°C in combination with the switch control method. This study provides a new method for the thermal control of electronic devices in the requirement of lightweight and miniaturization at low temperature environment.
