Rosavin improves insulin resistance and alleviates hepatic and kidney damage via modulating the cGAS-STING pathway and autophagy signaling in HFD/STZ-induced T2DM animals.

Background: Inflammation-mediated insulin resistance in type 2 diabetes mellitus (T2DM) increases complications, necessitating investigation of its mechanism to find new safe therapies. This study investigated the effect of rosavin on the autophagy and the cGAS-STING pathway-related signatures (ZBP1, STING1, DDX58, LC3B, TNF-α) and on their epigenetic modifiers (miR-1976 and lncRNA AC074117.2) that were identified from in silico analysis in T2DM animals. Methods: A T2DM rat model was established by combining a high-fat diet (HFD) and streptozotocin (STZ). After four weeks from T2DM induction, HFD/STZ-induced T2DM rats were subdivided into an untreated group (T2DM group) and three treated groups which received 10, 20, or 30 mg per kg of R. rosea daily for 4 weeks. Results: The study found that rosavin can affect the cGAS-STING pathway-related RNA signatures by decreasing the expressions of ZBP1, STING1, DDX58, and miR-1976 while increasing the lncRNA AC074117.2 level in the liver, kidney, and adipose tissues. Rosavin prevented further weight loss, reduced serum insulin and glucose, improved insulin resistance and the lipid panel, and mitigated liver and kidney damage compared to the untreated T2DM group. The treatment also resulted in reduced inflammation levels and improved autophagy manifested by decreased immunostaining of TNF-α and increased immunostaining of LC3B in the liver and kidneys of the treated T2DM rats. Conclusion: Rosavin has shown potential in attenuating T2DM, inhibiting inflammation in the liver and kidneys, and improving metabolic disturbances in a T2DM animal model. The observed effect was linked to the activation of autophagy and suppression of the cGAS-STING pathway.

Prevalence of major adverse cardiovascular events among Saudi patients with systemic lupus erythematosus compared with the general population: updates from the national SLE and PURE cohorts.

OBJECTIVE: This study examined the prevalence of major adverse cardiovascular events (MACE) among Saudi patients with SLE and the general population and considered factors associated with such outcomes were taken into consideration. METHODS: This is a cohort study evaluating the period prevalence of MACE from 2020 to 2023. The study used two datasets, namely the Saudi national prospective cohort for SLE patients and the Prospective Urban-Rural Epidemiology Study Saudi subcohort (PURE-Saudi) for the general population. Participants in both studies were monitored using a standardised protocol. MACE was defined as myocardial infarction (MI), stroke or angina. The analysis was adjusted for demographics, traditional cardiovascular risk factors and SLE diagnosis through logistic regression models. RESULTS: The PURE and national SLE cohorts comprised 488 and 746 patients, respectively. Patients with SLE from the SLE cohort were younger (40.7±12.5 vs 49.5±8.6 years) and predominantly female (90.6% vs 41.6%). The prevalence of traditional risk factors was greater in the PURE cohort compared with the SLE cohort. These factors included dyslipidaemia (28.9% vs 49.4%), obesity (63% vs 85%) and diabetes (7.8% vs 27.2%), but not hypertension (19.3% vs 18.8%). MACE (defined as MI or stroke or venous thromboembolism or heart failure) occurred more frequently in patients with SLE (4.3% vs 1.6%, p=0.004). Older age and lupus diagnosis were independently associated with MACE after adjusting for conventional risk factors. The odds of MACE were significantly related to age and lupus diagnosis (p=0.00 and p=0.00, respectively), but not cardiovascular disease (CVD) risk factors (p=0.83). CONCLUSION: Patients with SLE have a significantly higher risk of developing MACE than the general population. This risk is not well explained by traditional risk factors, which may explain the failure of CVD risk scores to stratify patients with SLE adequately. Further studies are needed to understand CVD risk's pathogenesis in SLE and mitigate it.

Hospital Unit Type and Professional Roles as a Predictor of Relational Coordination in an Army Medical Center.

BACKGROUND AND OBJECTIVES: High-quality communication and relationships are associated with quality of care. Workflow differences across hospital units can impede communication and relationships among health care professionals. Relational coordination (RC) is a process of communication supported by shared goals, shared knowledge, and mutual respect and is associated with quality of care and better performance outcomes in civilian hospitals. However, RC has not been explored in military hospitals. The objective of our study was to determine whether RC differs between hospital units and professional roles. Specifically, we examined RC differences by unit type for nurses, resident physicians, and physicians working in an Army Medical Center. METHODS: We conducted an exploratory analysis of a secondary question from a cross-sectional study using a convenience sample of active-duty and civilian licensed practical nurses (LPNs), registered nurses (RNs), physician residents, and physicians (n = 289). We received institutional review board approval from the study site. Data were collected from January 2020 to March 2020, and participants completed a 47-item survey regarding their experiences of RC in various hospital units. We used t tests and one-way analyses of variance to explore bivariate relationships between RC and other study variables, as well as multiple regression to explore whether RC varied by unit type. We controlled for education and experience by including them in the model because these variables may influence perceptions of nurse-physician RC and their interactions with each other. RESULTS: Seventy percent of participants were civilian (n = 203), 75% RNs (n = 217), and 78% female (n = 216). The mean age of respondents was 40 years (SD = 11.7), and the mean experience level was 11.9 years (SD = 9.5). RC was not associated with unit type. Total RC and between-role RC were associated with professional role. Physicians reported higher RC (ß = .45, P = .01), and LPNs reported lower RC (ß = -.06, P = .01). Education and experience were associated with RC. Participants with less experience reported higher RC (ß = -.01, P = .00), and participants with graduate degrees reported lower RC (ß = -.62, P = .00). CONCLUSIONS: We recommend hospital leaders consider interventions to build interprofessional relationships, including interdisciplinary meetings, huddles, and structured communication tools. Improving RC among health care professionals is a cost-effective and unique way to enhance communication and collaboration among health care professionals across hospital units.

The Systemic Score May Identify Life-Threatening Evolution in Still Disease: Data from the GIRRCS AOSD-Study Group and the AIDA Network Still Disease Registry.

OBJECTIVE: We aimed to evaluate the clinical usefulness of the systemic score in the prediction of life-threatening evolution in Still disease. We also aimed to assess the clinical relevance of each component of the systemic score in predicting life-threatening evolution and to derive patient subsets accordingly. METHODS: A multicenter, observational, prospective study was designed including patients included in the Gruppo Italiano Di Ricerca in Reumatologia Clinica e Sperimentale Adult-Onset Still Disease Study Group and the Autoinflammatory Disease Alliance Network Still Disease Registry. Patients were assessed to see if the variables to derive the systemic score were available. The life-threatening evolution was defined as mortality, whatever the clinical course, and/or macrophage activation syndrome, a secondary hemophagocytic lymphohistiocytosis associated with a poor prognosis. RESULTS: A total of 597 patients with Still disease were assessed (mean ± SD age 36.6 ± 17.3 years; male 44.4%). The systemic score, assessed as a continuous variable, significantly predicted the life-threatening evolution (odds ratio [OR] 1.24; 95% confidence interval [CI] 1.07-1.42; P = 0.004). A systemic score ≥7 also significantly predicted the likelihood of a patient experiencing life-threatening evolution (OR 3.36; 95% CI 1.81-6.25; P < 0.001). Assessing the clinical relevance of each component of the systemic score, liver involvement (OR 1.68; 95% CI 1.48-2.67; P = 0.031) and lung disease (OR 2.12; 95% CI 1.14-4.49; P = 0.042) both significantly predicted life-threatening evolution. The clinical characteristics of patients with liver involvement and lung disease were derived, highlighting their relevance in multiorgan disease manifestations. CONCLUSION: The clinical utility of the systemic score was shown in identifying Still disease at a higher risk of life-threatening evolution in a large cohort. Furthermore, the clinical relevance of liver involvement and lung disease was highlighted.

Clinical and laboratory features associated with macrophage activation syndrome in Still's disease: data from the international AIDA Network Still's Disease Registry.

To characterize clinical and laboratory signs of patients with Still's disease experiencing macrophage activation syndrome (MAS) and identify factors associated with MAS development. Patients with Still's disease classified according to internationally accepted criteria were enrolled in the AutoInflammatory Disease Alliance (AIDA) Still's Disease Registry. Clinical and laboratory features observed during the inflammatory attack complicated by MAS were included in univariate and multivariate logistic regression analysis to identify factors associated to MAS development. A total of 414 patients with Still's disease were included; 39 (9.4%) of them developed MAS during clinical history. At univariate analyses, the following variables were significantly associated with MAS: classification of arthritis based on the number of joints involved (p = 0.003), liver involvement (p = 0.04), hepatomegaly (p = 0.02), hepatic failure (p = 0.01), axillary lymphadenopathy (p = 0.04), pneumonia (p = 0.03), acute respiratory distress syndrome (p < 0.001), platelet abnormalities (p < 0.001), high serum ferritin levels (p = 0.009), abnormal liver function tests (p = 0.009), hypoalbuminemia (p = 0.002), increased LDH (p = 0.001), and LDH serum levels (p < 0.001). At multivariate analysis, hepatomegaly (OR 8.7, 95% CI 1.9-52.6, p = 0.007) and monoarthritis (OR 15.8, 95% CI 2.9-97.1, p = 0.001), were directly associated with MAS, while the decade of life at Still's disease onset (OR 0.6, 95% CI 0.4-0.9, p = 0.045), a normal platelet count (OR 0.1, 95% CI 0.01-0.8, p = 0.034) or thrombocytosis (OR 0.01, 95% CI 0.0-0.2, p = 0.008) resulted to be protective. Clinical and laboratory factors associated with MAS development have been identified in a large cohort of patients based on real-life data.

Classical phenylketonuria presenting as maternal PKU syndrome in the offspring of an intellectually normal woman.

Phenylketonuria (PKU) is an autosomal recessive inborn error of metabolism resulting from a deficiency of phenylalanine hydroxylase (PAH). If untreated by dietary restriction of phenylalanine intake, impaired postnatal cognitive development results from the neurotoxic effects of excessive phenylalanine (Phe). Signs and symptoms include severe intellectual disability and behavior problems with a high frequency of seizures and variable microcephaly. Maternal PKU syndrome refers to fetal damage resulting in congenital abnormalities when the mother has untreated PKU during pregnancy. Here, we report an intellectually normal 32-year-old female who presented with recurrent pregnancy loss and two neonatal deaths with congenital heart disease, microcephaly, intrauterine growth restriction, and respiratory distress. She was diagnosed with PKU through exome sequencing performed for carrier testing with a homozygous pathogenic variant in the PAH gene, c.169_171del, p.(Glu57del) that is associated with classical PKU. Consistent with the genetic finding, she had a markedly increased plasma phenylalanine concentration of 1642 µmol/L (normal <100). This case demonstrates that recurrent pregnancy loss due to untreated maternal PKU may present as an initial finding in otherwise unsuspected classical PKU and illustrates that extreme degrees of variable expressivity may occur in classical PKU. Moreover, this case illustrates the value of genomic sequencing of women who experience recurrent pregnancy loss or neonatal anomalies.

A relational coordination training intervention to improve job satisfaction and intent to stay in the intensive care unit: A pilot study.

BACKGROUND: Relational coordination (RC) explores the coordination of work between and among professionals in a workgroup. RC is associated with higher job satisfaction and retention; however, researchers have not tested RC training interventions to improve job satisfaction and retention. PURPOSE: To explore changes in job satisfaction and intent to stay among health care professionals following a virtual RC training intervention. METHODS: We conducted a pilot, parallel group randomized controlled trial in four intensive care units. Data collection occurred via survey. Difference-in-difference regression models were used to analyze the job satisfaction and intent to stay outcomes. DISCUSSION: The RC training intervention did not influence job satisfaction or intent to stay. Participants with baccalaureate degrees and African American/Black participants reported lower intent to stay. CONCLUSION: The results from this pilot study are a critical first step in testing the efficacy of an RC training intervention to improve staff outcomes in a larger powered study.

The Metal-Oxide Nanoparticle-Aqueous Solution Interface Studied by Liquid-Microjet Photoemission.

ConspectusThe liquid-microjet technique combined with soft X-ray photoelectron spectroscopy (PES) has become an exceptionally powerful experimental tool to investigate the electronic structure of liquid water and nonaqueous solvents and solutes, including nanoparticle (NP) suspensions, since its first implementation at the BESSY II synchrotron radiation facility 20 years ago. This Account focuses on NPs dispersed in water, offering a unique opportunity to access the solid-electrolyte interface for identifying interfacial species by their characteristic photoelectron spectral fingerprints. Generally, the applicability of PES to a solid-water interface is hampered due to the small mean free path of the photoelectrons in solution. Several approaches have been developed for the electrode-water system and will be reviewed briefly. The situation is different for the NP-water system. Our experiments imply that the transition-metal oxide (TMO) NPs used in our studies reside close enough to the solution-vacuum interface that electrons emitted from the NP-solution interface (and from the NP interior) can be detected.We were specifically exploring aqueous-phase TMO NPs that have a high potential for (photo)electrocatalytic applications, e.g., for solar fuel generation. The central question we address here is how H2O molecules interact with the respective TMO NP surface. Liquid-microjet PES experiments, performed from hematite (α-Fe2O3, iron(III) oxide) and anatase (TiO2, titanium(IV) oxide) NPs dispersed in aqueous solutions, exhibit sufficient sensitity to distinguish between free bulk-solution water molecules and those adsorbed at the NP surface. Moreover, hydroxyl species resulting from dissociative water adsorption can be identified in the photoemission spectra. An important aspect is that in the NP(aq) system the TMO surface is in contact with a true extended bulk electrolyte solution rather than with a few monolayers of water, as is the case in experiments using single-crystal samples. This has a decisive effect on the interfacial processes that can occur since NP-water interactions can be uniquely investigated as a function of pH and provides an environment allowing for unhindered proton migration. Our studies confirm that water is dissociatively adsorbed at the hematite surface and molecularly adsorbed at the TiO2 NP surface at low pH. In contrast, at near-basic pH the water interaction is dissociative at the TiO2 NP surface.The liquid-microjet measurements presented here also highlight the multiple aspects of photoemission necessary for a full characterization of TMO nanoparticle surfaces in aqueous environments. For instance, we exploit the ability to increase species-specific electron signals via resonant photoemission, so-called partial electron yield X-ray absorption (PEY-XA) spectra, and from valence photoelectron and resonant Auger-electron spectra. We also address the potential of these resonance processes and the associated ultrafast electronic relaxations for determining charge transfer or electron delocalization times, e.g., from Fe3+ located at the hematite nanoparticle interface into the aqueous-solution environment.

Relationships and resilience at work and at home: Impact of relational coordination on clinician work-life balance and well-being in times of crisis.

BACKGROUND: The COVID-19 pandemic has been an unusually comprehensive crisis that has taken a toll on people in their roles both at work and at home, giving rise to a new normal. PURPOSE: Relational coordination theory shows how communicating and relating for the purpose of task integration drives positive outcomes for workers, their clients, and their employers. The ecological theory of work-family spillover shows how relational dynamics from work spillover into family life, and vice versa. We build upon these two theories to understand how relationships at work impact work-life balance and worker well-being, especially in times of crisis. METHODOLOGY: This study was based on surveys of clinicians affiliated with a large California health system during the COVID-19 pandemic. Mediation and multilevel logistic regression models were used to assess how relational coordination among colleagues impacts well-being (job satisfaction and lack of burnout) through its effects on work-life balance (schedule control and personal time). RESULTS: A 1-point increase in relational coordination tripled clinician odds of having schedule control ( OR = 3.33, p < .001) and nearly doubled the odds of having adequate personal time ( OR = 1.83, p < .001). A 1-point increase in relational coordination nearly quadrupled odds of being satisfied with their job ( OR = 3.92, p < .001) and decreased odds of burnout by 64% ( OR = 0.36, p < .001). The impact of relational coordination on worker well-being was mediated by greater schedule control and personal time. CONCLUSION: Relational coordination among colleagues impacts worker well-being by enabling greater control over one's schedule and more personal time, thus creating a positive spillover from work to home in times of crisis. PRACTICE IMPLICATIONS: In times of crisis, leaders should prioritize relational coordination among colleagues in order to support their resilience both at work and at home.

Assessing relational coordination and its impact on perceived mental health of students, teachers and staff in a clinical skills program during the COVID-19 pandemic.

BACKGROUND: The global spread of the COVID-19 virus caused unprecedented interruptions in medical education. This paper evaluates Relational Coordination (RC): communicating and relating for task integration; between the distinct stakeholders responsible for scheduling,delivering and receiving clinical teaching in the wake of the pandemic. METHODOLOGY: Using a cross-sectional design, the level of Relational Coordination was assessed between twelve groups within a Clinical Skills Program at a Medical School in the United Arab Emirates. It also measures three relevant mental health factors: namely, Job satisfaction, Work Engagement, and Burnout. RESULTS: Overall, RC scores were moderate (3.65 out of 5.00). Controlling for participants' position, RC was found to positively and significantly increase both job satisfaction (ß = 1.10, p < 0.001) and work engagement (ß = 0.78, p < 0.01)., Additionally, RC was significantly associated with lower burnout (ß = -0.56, p = 0.05). Fifty percent of participants experienced high job satisfaction, with a mean score of 5.0 out of 7.0, while 73% reported being enthusiastic about their job, with a mean score of 6.0 out of 7.0. About a third of participants (27%) reported feeling burnout. CONCLUSIONS: During times of disruption and crisis, medical education can benefit from higher levels of relational coordination. Our study shows the significant impact of relational coordination on mental health measures like job satisfaction and work engagement. To achieve the full potential and benefits of excellent levels of relational coordination in this program, we recommend six interventions focusing on improving communication, work processes, regular meetings, education innovations, capacity building, and the establishment of coaching and counseling programs for students and faculty.

Strengthening networks for healthcare integration: A commentary.

In their paper "Integrating Network Theory into the Study of Integrated Healthcare," Burns, Nembhard and Shortell set out to change how we think about healthcare, and ultimately how we design and deliver healthcare. They aim to do this by focusing attention on the networks through which care is delivered, with particular attention to the relational dimensions of those networks. Inspired by social network, care integration, and relational coordination theories, Burns et al. (2022) offer recommendations for moving the healthcare sector toward a fresh approach to care integration that reflects the realities of relationships and networks. In this commentary, we analyze the main recommendations by Burns et al. and present our view of the field's current standing with regards to each of them. We then suggest potential research questions, contexts and designs to move this proposed work forward, drawing upon insights from a conversation with the authors in addition to their original article. We end by recommending the formation of a research collaborative to carry out the work.

Strengthening Community Participation by People With Disabilities in Community-Based Group Homes Through Innovative Action Research.

In the US and beyond, a paradigm shift is underway toward community-based care, motivated by changes in policies, payment models and social norms. A significant aspect of this shift for disability activists and policy makers is ensuring participation in community life for individuals with disabilities living in residential homes. Despite a U.S. government ruling that encourages community participation and provides federal and state funding to realize it, little progress has been made. This study builds on and integrates the expanded model of value creation with relational coordination theory by investigating how the resources and relationships between care providers, adults with disabilities, family members, and community members can be leveraged to create value for residents through meaningful community participation. The purpose of our community case study was to assess and improve the quality of relationships between stakeholder groups, including direct care staff and managers, residents, family members, and the community through an action research intervention. This study took place in a residential group home in a Northeastern US community serving adults with disabilities from acquired brain injury. A pre-test post-test design was used and quantitative assessments of relational coordination were collected through electronic surveys, administered at baseline, and post-intervention. Direct care staff, supervisors, the house manager, and nursing staff completed the survey. Qualitative data were collected through focus groups, change team meetings, and key informant interviews. Direct care staff formed a change team to reflect on their baseline relational coordination data and identified the weak ties between direct care staff, family members, and the community as an area of concern. Staff chose to hold a community-wide open house to provide an opportunity to foster greater understanding among staff, residents, family, and community members. The change team and other staff members coordinated with local schools, business owners, town officials, churches, and neighbors. The event was attended by 50 people, about two-thirds from the community. Following the intervention, there was an increase in staff relational coordination with the community. While statistical significance could not be assessed, the change in staff RC with the community was considered qualitatively significant in that real connections were made with members of the community both directly and afterwards. Despite a small sample size, a residential setting where management was favorable to initiating staff-led interventions, and no comparison or control group, our small pilot study provides tentative evidence that engaging direct care staff in efforts to improve relational coordination with community members may succeed in building relationships that are essential to realizing the goal of greater participation in community life.

Adaptations to relational facilitation for two national care coordination programs during COVID-19.

Background: Adaptations to implementation strategies are often necessary to support adoption and scale-up of evidence-based practices. Tracking adaptations to implementation strategies is critical for understanding any impacts on outcomes. However, these adaptations are infrequently collected. In this article we present a case study of how we used a new method during COVID-19 to systematically track and report adaptations to relational facilitation, a novel implementation strategy grounded in relational coordination theory. Relational facilitation aims to assess and improve communication and relationships in teams and is being implemented to support adoption of two Quadruple Aim Quality Enhancement Research Initiative (QA QUERI) initiatives: Care Coordination and Integrated Case Management (CC&ICM) and the Transitions Nurse Program for Home Health Care (TNP-HHC) in the Veterans Health Administration (VA). Methods: During 2021-2022, relational facilitation training, activities and support were designed as in-person and/or virtual sessions. These included a site group coaching session to create a social network map of care coordination roles and assessment of baseline relationships and communication between roles. Following this we administered the Relational Coordination Survey to assess the relational coordination strength within and between roles. COVID-19 caused challenges implementing relational facilitation, warranting adaptations. We tracked relational facilitation adaptations using a logic model, REDCap tracking tool based on the Framework for Reporting Adaptations and Modifications-Enhanced (FRAME) with expanded Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) dimensions, and member checking. Adaptations were analyzed descriptively and for themes using matrix content analysis. Results: COVID-19's impact within the VA caused barriers for implementing relational facilitation, warranting eight unique adaptations to the implementation strategy. Most adaptations pertained to changing the format of relational facilitation activities (n = 6; 75%), were based on external factors (n = 8; 100%), were planned (n = 8; 100%) and initiated by the QA QUERI implementation team (n = 8; 100%). Most adaptations impacted adoption (n = 6; 75%) and some impacted implementation (n = 2; 25%) of the CC&ICM and TNP-HHC interventions. Discussion: Systematically tracking and discussing adaptations to relational facilitation during the COVID-19 pandemic enhanced engagement and adoption of two VA care coordination interventions. The impact of these rapid, early course adaptations will be followed in subsequent years of CC&ICM and TNP-HHC implementation.

Spectroscopic evidence for a gold-coloured metallic water solution.

Insulating materials can in principle be made metallic by applying pressure. In the case of pure water, this is estimated1 to require a pressure of 48 megabar, which is beyond current experimental capabilities and may only exist in the interior of large planets or stars2-4. Indeed, recent estimates and experiments indicate that water at pressures accessible in the laboratory will at best be superionic with high protonic conductivity5, but not metallic with conductive electrons1. Here we show that a metallic water solution can be prepared by massive doping with electrons upon reacting water with alkali metals. Although analogous metallic solutions of liquid ammonia with high concentrations of solvated electrons have long been known and characterized6-9, the explosive interaction between alkali metals and water10,11 has so far only permitted the preparation of aqueous solutions with low, submetallic electron concentrations12-14. We found that the explosive behaviour of the water-alkali metal reaction can be suppressed by adsorbing water vapour at a low pressure of about 10-4 millibar onto liquid sodium-potassium alloy drops ejected into a vacuum chamber. This set-up leads to the formation of a transient gold-coloured layer of a metallic water solution covering the metal alloy drops. The metallic character of this layer, doped with around 5 × 1021 electrons per cubic centimetre, is confirmed using optical reflection and synchrotron X-ray photoelectron spectroscopies.

Clinical and Genetic Characterization of Craniosynostosis in Saudi Arabia.

Background: Craniosynostosis (CS) is defined as pre-mature fusion of one or more of the cranial sutures. CS is classified surgically as either simple or complex based on the number of cranial sutures involved. CS can also be classified genetically as isolated CS or syndromic CS if the patient has extracranial deformities. Currently, the link between clinical and genetic patterns of CS in the Saudi population is poorly understood. Methodology: We conducted a retrospective cohort study among 28 CS patients, of which 24 were operated and four were not. Clinical and genetic data were collected between February 2015 and February 2019, from consenting patient's families. The electronic chart data were collected and analyzed including patient demographics, craniofacial features, other anomalies and dysmorphic features, operative data, intra cranial pressure (ICP), parent consanguinity and genetic testing results. Results: The most common deformity in our population was trigonocephaly. The most performed procedure was cranial vault reconstruction with fronto-orbital advancement, followed by posterior vault distraction osteogenesis and suturectomy with barrel staving. Genetics analysis revealed pathogenic mutations in FGFR2 (6 cases), TWIST1 (3 cases), ALPL (2 cases), and TCF12 (2 cases), and FREM1 (2 case). Conclusion: Compared to Western countries, our Saudi cohort displays significant differences in the prevalence of CS features, such as the types of sutures and prevalence of inherited CS. The genomic background allows our phenotype-genotype study to reclassify variants of unknown significance. Worldwide, the sagittal suture is the most commonly affected suture in simple CS, but in the Saudi population, the metopic suture fusion was most commonly seen in our clinic. Further studies are needed to investigate the characteristics of CS in our population in a multicenter setting.

Low-energy constraints on photoelectron spectra measured from liquid water and aqueous solutions.

We report on the effects of electron collision and indirect ionization processes, occurring at photoexcitation and electron kinetic energies well below 30 eV, on the photoemission spectra of liquid water. We show that the nascent photoelectron spectrum and, hence, the inferred electron binding energy can only be accurately determined if electron energies are large enough that cross sections for quasi-elastic scattering processes, such as vibrational excitation, are negligible. Otherwise, quasi-elastic scattering leads to strong, down-to-few-meV kinetic energy scattering losses from the direct photoelectron features, which manifest in severely distorted intrinsic photoelectron peak shapes. The associated cross-over point from predominant (known) electronically inelastic to quasi-elastic scattering seems to arise at surprisingly large electron kinetic energies, of approximately 10-14 eV. Concomitantly, we present evidence for the onset of indirect, autoionization phenomena (occurring via superexcited states) within a few eV of the primary and secondary ionization thresholds. These processes are inferred to compete with the direct ionization channels and primarily produce low-energy photoelectrons at photon and electron impact excitation energies below ∼15 eV. Our results highlight that vibrational inelastic electron scattering processes and neutral photoexcitation and autoionization channels become increasingly important when photon and electron kinetic energies are decreased towards the ionization threshold. Correspondingly, we show that for neat water and aqueous solutions, great care must be taken when quantitatively analyzing photoelectron spectra measured too close to the ionization threshold. Such care is essential for the accurate determination of solvent and solute ionization energies as well as photoelectron branching ratios and peak magnitudes.

Sustaining improvements in relational coordination following team training and practice change: A longitudinal analysis.

BACKGROUND: Poor communication is a leading cause of errors in health care. Structured interprofessional bedside rounds are a promising model to improve communication. PURPOSE: The aim of the study was to test if an intervention to improve communication and coordination in an inpatient heart failure care unit would result in lasting change. METHODOLOGY/APPROACH: The relational coordination (RC) survey was administered to seven workgroups (i.e., nurses, physicians) at baseline (2015) and three subsequent years following the intervention (team training, leadership development workshops, and structured interprofessional bedside round implementation). Descriptive analysis and mixed-effects models were used to assess the impact of the intervention on improving RC. RESULTS: During the study period (2015-2018), 344 participants completed the survey for an overall response rate of 53.5% (n = 643). Postintervention, the RC index significantly increased from 3.79 to 4.08 (p < .001) and remained significantly higher over 2 years, with an RC index of 4.12 and 4.04, respectively (p < .001). The range of RC scores between and within workgroups narrowed over time, with nonrotating workgroups showing the most improvements. CONCLUSION: Findings indicate that positive changes as a result of the intervention have been sustained, despite high rates of turnover among all workgroups. Notably, positive change in RC was found to be more pronounced for nonrotating workgroups compared to team members who rotate within the hospital (i.e., pharmacists who rotate to other units every month). PRACTICE IMPLICATIONS: This intervention holds promise for teams seeking best practice models of "high-reliability" care organization and delivery. Sustained changes from this intervention represent an important area of future practice-based research.

Photoelectron spectra of alkali metal-ammonia microjets: From blue electrolyte to bronze metal.

Experimental studies of the electronic structure of excess electrons in liquids-archetypal quantum solutes-have been largely restricted to very dilute electron concentrations. We overcame this limitation by applying soft x-ray photoelectron spectroscopy to characterize excess electrons originating from steadily increasing amounts of alkali metals dissolved in refrigerated liquid ammonia microjets. As concentration rises, a narrow peak at ~2 electron volts, corresponding to vertical photodetachment of localized solvated electrons and dielectrons, transforms continuously into a band with a sharp Fermi edge accompanied by a plasmon peak, characteristic of delocalized metallic electrons. Through our experimental approach combined with ab initio calculations of localized electrons and dielectrons, we obtain a clear picture of the energetics and density of states of the ammoniated electrons over the gradual transition from dilute blue electrolytes to concentrated bronze metallic solutions.

Effect of RNA Interference on the Hepatitis C Virus Core Expression in HepG2/C3A Cells Using Genotype 4 Isolates from Saudi Patients.

OBJECTIVE: To explore the effects of two different methodologies of RNA interference, namely small interfering RNA, and vector-based short hairpin RNA, on the expression levels of hepatitis C virus core RNA and protein of Saudi genotype 4 isolates. STUDY DESIGN: An experimental study. PLACE AND DURATION OF STUDY: Laboratories of the College of Medicine Research Center, King Saud University, Saudi Arabia, from January to December 2018. METHODOLOGY: Hepatitis C virus core small interfering RNA molecule and short hairpin RNA vector were designed against core region. Viral RNA expression was tested by RT-PCR; whereas, core protein was tested by flow cytometry and immunofluorescence. Results were statistically analysed by Chi-square analysis to calculate the p-value. RESULTS: Both molecules caused a reduction in core RNA and protein expression in infected cells. The effect of 100-pmol of small interfering RNA was more evident. For the vector-based short hairpin RNA, inhibition of core RNA expression was quite evident after 96 hours (p = 0.007). The results of flow cytometry and immunofluorescence showed a decline in core protein expression. The most dramatic effect was observed with 100-pmol small interfering RNA treatment of cells for 24 and 48 hours, which resulted in 63.5% and 91.1% core RNA expression reduction, respectively. CONCLUSION: RNA interference of hepatitis C virus core gene efficiently stopped viral replication and offer a promising therapeutic alternative against virus infection.
