Ion receptors are molecular hosts that bind ionic guests, often with great selectivity. The interplay of solvation and ion binding in anion host-guest complexes in solution governs the binding efficiency and selectivity of such ion receptors. To gain molecular-level insight into the intrinsic binding properties of octamethyl calix[4]pyrrole (omC4P) host molecules with halide guest ions, we performed cryogenic ion vibrational spectroscopy (CIVS) of omC4P in complexes with fluoride, chloride, and bromide ions...

A cube-like Zn(II)-Eu(III) nanocluster 1 (molecular sizes: 1.8 × 2.0 × 2.0 nm) was constructed by the use of a new long-chain Schiff base ligand. It shows a ratiometric fluorescence response to levofloxacin (LFX) with high sensitivity and selectivity, which can be expressed as I 615 nm / I 550 nm = A *[LFX]2 + B *[LFX] + C . It is used to quantitatively detect the LFX concentrations in fetal calf serum (FCS) and tablets sold in pharmacy. Filter paper strips bearing 1 can be used to qualitatively detect LFX by a color change to red under a UV lamp...

Abuse is a social concern in all life affairs including sports. This qualitative phenomenological study aimed to explore the lived experience of Iranian athletes who had been abused in sports. The participants were six athletes who had experienced abuse in sports. Due to the sensitivity of the issue, they were selected through the purposeful snowball sampling method. The results of the research showed seven main themes in the Iranian athletes' experience of abuse in sports: (1) stigma, (2) suppressed hatred and anger, (3) psychological pendulum of continuing and abandoning sport, (4) trampled emotions, (5) ambiguity and imposed harassment, (6) victimhood, and (7) feelings of self-blame...

Understanding the mechanisms of C-H activation of alkanes is a very important research topic. The reactions of metal clusters with alkanes have been extensively studied to reveal the electronic features governing C-H activation, while the experimental cluster reactivity was qualitatively interpreted case by case in the literature. Herein, we prepared and mass-selected over 100 rhodium-based clusters (Rh x V y O z - and Rh x Co y O z - ) to react with light alkanes, enabling the determination of reaction rate constants spanning six orders of magnitude...

In this work, we propose and validate a generalization of the Helmholtz model that can account for both "bell-shaped" and "camel-shaped" differential capacitance profiles of concentrated electrolytes, the latter being characteristic of ionic liquids. The generalization is based on introducing voltage dependence of both the dielectric constant "ϵr(V)" and thickness "L(V)" of the inner Helmholtz layer, as validated by molecular dynamics (MD) simulations. We utilize MD simulations to study the capacitance profiles of three different electrochemical interfaces: (1) graphite/[BMIm+][BF4-] ionic liquid interface; (2) Au(100)/[BMIm+][BF4-] ionic liquid interface; (3) Au(100)/1M [Na+][Cl-] aqueous interface...

Molecular chirality has traditionally been viewed as a binary property where a molecule is classified as either chiral or achiral, yet in recent decades, mathematical methods for quantifying chirality have been explored. Here, we use toy molecular systems to systematically compare the performance of two state-of-the-art chirality measures: (1) the Continuous Chirality Measure (CCM) and (2) the Chirality Characteristic (χ). We find that both methods exhibit qualitatively similar behavior when applied to simple molecular systems such as a four-site molecule or the polymer double-helix, but we show that the CCM may be more suitable for evaluating the chirality of arbitrary molecules or abstract structures such as normal vibrational modes...

BACKGROUND: Despite the exponential growth of mobile device applications in promoting awareness on traumatic dental injuries (TDIs), the overall validity of existing applications in content, engagement, usability, functionality, esthetics, and user perception remains largely uncertain. AIMS: The primary aim was to systematically search and assess the quality, functionality, perceived impact and usability of available applications related to TDIs using the User Version of the Mobile Application Rating Scale (uMARS) and the Coventry, Aberdeen, and London-Revised (CA-LO-RE) scale...

BACKGROUND: Few studies have been conducted on young people's attitudes to the COVID-19 vaccine during the pandemic. We wished to examine how young people with an ethnic minority background decided whether to have the COVID-19 vaccine, based on the concept of vaccine hesitancy. Vaccine hesitancy involves uncertainty with regard to vaccination, irrespective of the decision taken. MATERIAL AND METHOD: Fourteen qualitative in-depth interviews with young people aged 16-25 years with an ethnic minority background and from the east side of Oslo were analysed and categorised into main themes...

BACKGROUND: We wished to examine the role of the district medical officer in five Norwegian municipalities to provide new knowledge of how the experience from the pandemic might have led to changes to the district medical officer's role. MATERIAL AND METHOD: Semi-structured interviews were conducted with 14 persons who had held key positions in local crisis management teams during and after the pandemic. The informants were recruited from five municipalities within the same county, and they all held leadership roles in health care (district medical officers), local politics or administration...

Weaning and liberation from VA ECMO in cardiogenic shock patients comprises a complex process requiring a continuous trade off between multiple clinical parameters. In the absence of dedicated international guidelines, we hypothesized a great heterogeneity in weaning practices among ECMO centers due to a variety in local preferences, logistics, case load and individual professional experience. This qualitative study focused on the appraisal of clinicians' preferences in decision processes towards liberation from VA ECMO after cardiogenic shock while using focus group interviews in 4 large hospitals...

It is recommended that health promotion activities in the community focus on residents' strengths. Hence, this study explored the community strengths perceived by older adults living alone in a semi-mountainous rural region of Japan. A qualitative, descriptive approach was used. Content analysis was performed using data obtained through face-to-face interviews. Interview data were coded; codes were classified based on similarity to create subcategories and categories. The strengths within the community, as perceived by older adults living alone in a semi-mountainous rural region, were revealed in four categories related to ten subcategories: "loose connections with others", "active community participation", "close relationships with community professionals", and "familiarity with the living environment"...

BACKGROUND: Aging populations are driving a shift in emphasis toward enhancing chronic disease care, reflected in Catalonia's regional plan which prioritizes standardized nursing care plans in primary care settings. To achieve this, the ARES-AP program was established with a focus on harmonizing standards and supporting routine nursing clinical decision-making. This study evaluates nurses' perceptions of ARES-AP's standardized care plans for chronic diseases. METHODS: A mixed-methods approach based on an ad hoc questionnaire (n = 141) and a focus group (n = 14) was used...

AIM: Our goal was to explore how power asymmetry manifests within the relationships between students, teachers, and supervisors, and how it influences students' ability for critical reflection. DESIGN: This study has an explorative qualitative design. METHODS: Thirty in-depth interviews with nursing students (15), teachers (9), and supervisors (6) were conducted in addition to 16 observations of mid-term assessments during clinical practice...

Background: The concept of unfinished nursing care (UNC) describes nursing interventions required by patients and families that nurses postpone or omit. UNC reasons have been documented; however, no studies have summarised the underlying factors triggering the UNC during the pandemic. Therefore, the aim was to synthesise the available studies exploring factors affecting UNC during a pandemic. Methods: We conducted an integrative review following Whittemore and Knafl's framework according to the Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines...

(1) Background: Studies have shown that clinical experience has an impact on how students perceive geriatric care. The vulnerability of older people particularly allows students to reflect on and evaluate their learning. In this context, communication between tutors and students is important to guiding a contextualized view of the complexity of clinical situations. The principal objective was to explore the feelings, perceptions, and experiences of nursing students in geriatric care units during their practices...

Withdrawal of Life-Sustaining Treatment in the PICU From the Nursing Staff's Perspective: Integrative Review Abstract: Background: Withdrawal of life sustaining measures is a common mode of treatment prior to the death of a critically ill child and has implications for all involved. The perspective of nurses has not yet been considered in this context. Aim: How do nurses experience the termination of life-sustaining measures in the paediatric intensive care unit? What is their role in this process? Methods: An integrative review was conducted to answer the research question...

The Connecticut Newborn Screening (NBS) Network, in partnership with the Connecticut Department of Public Health, strategically utilized the Epic electronic health record (EHR) system to establish registries for tracking long-term follow-up (LTFU) of NBS patients. After launching the LTFU registry in 2019, the Network obtained funding from the Health Resources and Services Administration to address the slow adoption by specialty care teams. An LTFU model was implemented in the three highest-volume specialty care teams at Connecticut Children's, involving an early childhood cohort diagnosed with an NBS-identified disorder since the formation of the Network in March 2019...

While light at night (LAN) and noise levels have been linked to suboptimal sleep outcomes, little is known about the link between these factors and long-term suboptimal sleep trajectories. The current study examined the association of neighborhood LAN and nighttime noise with long-term sleep trajectories in a cohort of Black individuals and White individuals predominantly from low-income communities. We used data from the Southern Community Cohort Study (N = 28,759 Black individuals and 16,276 White individuals)...
