A case report on rapid development of simultaneous liver and musculature calcifications in severe sepsis.

A 76-year-old Malay female presented with 2 days history of fever and vomiting. She was found to have Escherichia coli and Klebsiella pneumoniae bacteraemia with no clear intra-abdominal cause on the initial computed tomography of the abdomen and pelvis (CTAP). She clinically improved with 2 weeks duration of intravenous meropenem. She subsequently developed septic shock and a repeated CTAP demonstrated increased hepatic parenchymal density with extensive parenchymal calcifications. Curvilinear calcifications were seen in the paraspinal and pelvic musculature.

Randomized Phase II Study of Gemcitabine With or Without ATR Inhibitor Berzosertib in Platinum-Resistant Ovarian Cancer: Final Overall Survival and Biomarker Analyses.

PURPOSE: The multicenter, open-label, randomized phase 2 NCI-9944 study (NCT02595892) demonstrated that addition of ATR inhibitor (ATRi) berzosertib to gemcitabine increased progression-free survival (PFS) compared to gemcitabine alone (hazard ratio [HR]=0.57, one-sided log-rank P = .044, which met the one-sided significance level of 0.1 used for sample size calculation). METHODS: We report here the final overall survival (OS) analysis and biomarker correlations (ATM expression by immunohistochemistry, mutational signature 3 and a genomic biomarker of replication stress) along with post-hoc exploratory analyses to adjust for crossover from gemcitabine to gemcitabine/berzosertib. RESULTS: At the data cutoff of January 27, 2023 (>30 months of additional follow-up from the primary analysis), median OS was 59.4 weeks with gemcitabine/berzosertib versus 43.0 weeks with gemcitabine alone (HR 0.79, 90% CI 0.52 to 1.2, one-sided log-rank P = .18). An OS benefit with addition of berzosertib to gemcitabine was suggested in patients stratified into the platinum-free interval ≤3 months (N = 26) subgroup (HR, 0.48, 90% CI 0.22 to 1.01, one-sided log-rank P =.04) and in patients with ATM-negative/low (N = 24) tumors (HR, 0.50, 90% CI 0.23 to 1.08, one-sided log-rank P = .06). CONCLUSION: The results of this follow-up analysis continue to support the promise of combined gemcitabine/ATRi therapy in platinum resistant ovarian cancer, an active area of investigation with several ongoing clinical trials.

Centralized Interactive Phenomics Resource: an integrated online phenomics knowledgebase for health data users.

OBJECTIVE: Development of clinical phenotypes from electronic health records (EHRs) can be resource intensive. Several phenotype libraries have been created to facilitate reuse of definitions. However, these platforms vary in target audience and utility. We describe the development of the Centralized Interactive Phenomics Resource (CIPHER) knowledgebase, a comprehensive public-facing phenotype library, which aims to facilitate clinical and health services research. MATERIALS AND METHODS: The platform was designed to collect and catalog EHR-based computable phenotype algorithms from any healthcare system, scale metadata management, facilitate phenotype discovery, and allow for integration of tools and user workflows. Phenomics experts were engaged in the development and testing of the site. RESULTS: The knowledgebase stores phenotype metadata using the CIPHER standard, and definitions are accessible through complex searching. Phenotypes are contributed to the knowledgebase via webform, allowing metadata validation. Data visualization tools linking to the knowledgebase enhance user interaction with content and accelerate phenotype development. DISCUSSION: The CIPHER knowledgebase was developed in the largest healthcare system in the United States and piloted with external partners. The design of the CIPHER website supports a variety of front-end tools and features to facilitate phenotype development and reuse. Health data users are encouraged to contribute their algorithms to the knowledgebase for wider dissemination to the research community, and to use the platform as a springboard for phenotyping. CONCLUSION: CIPHER is a public resource for all health data users available at https://phenomics.va.ornl.gov/ which facilitates phenotype reuse, development, and dissemination of phenotyping knowledge.

[Excelling in the AI Era: Cultivating AI Literacy].

In light of the rapid advancements in artificial intelligence (AI), the future of the nursing profession is expected to be closely intertwined with AI applications. In response to this challenge, nursing educators must cultivate AI literacy in students to ensure their ability to communicate and collaborate effectively with their interdisciplinary peers. Nursing educators should comprehend the essence of AI literacy, integrate AI literacy into their curriculum designs, and regularly assess the effectiveness of AI literacy cultivation efforts among their students to ensure nursing graduates are able to effectively fulfill their roles in nursing and healthcare. The purpose of this paper is to explain the essence of AI literacy, approaches for cultivating AI literacy in students, and methods for assessing AI literacy with the aim of educating nursing students to become competent nurses for tomorrow.

[Embracing the Era of Artificial Intelligence: Innovation and Preparation in Nursing Education].

Rapid recent advances in information technology have opened the door for artificial intelligence (AI)-related technologies to be applied extensively across many industries. The Ministry of Education has emphasized the importance of cultivating advanced-level professionals in diverse fields, particularly in smart machinery, the Asia-Silicon Valley sector, green energy technology, biotechnology, national defense, new agricultural, and circular economy industries, to enhance innovation and promote industrial competitiveness (Kuo, 2019). While interdisciplinary talent in AI and digital innovation is being actively developed elsewhere, nursing education remains in the exploratory phase of AI and digital technology talent cultivation. Although AI is now a well-known term, the competencies required for its application in nursing remain unclear. Moreover, most nursing professionals are unfamiliar with how to best integrate AI into nursing expertise or practice settings. With the application of AI in the healthcare industry now unstoppable, it is vital to consider how to help nursing students adapt to healthcare's new technology landscape (Huang et al., 2021). AI facilitates the digital simulation of human thought patterns, logic, and behaviors with the goal of assisting human users solve problems, especially those that are time-consuming and require repetitive processing. The development of AI requires interdisciplinary collaboration among domain experts, data scientists, software engineers, robotics experts, and computer programmers. Such collaboration is essential to developing products able to meet the demands of the times and to help students become competent future nursing professionals (Murray, 2018). Nurses spend the most time interacting with patients and are thus best able to understand the perceptions and challenges of patients and their families. Collaborating with professionals from interdisciplinary fields is the best strategy for achieving optimal healthcare outcomes. However, nursing schools have yet to provide a clear response to the impact of AI on nursing education. Nursing educational institutions must enable nursing students to comprehend the concepts and principles of AI and equip them with AI literacy to allow them to unleash their potential, continuously innovate, and stay abreast with the times (Ng et al., 2021). In this issue, experts and scholars currently engaged in AI-related research in the nursing discipline share their research findings in the realms of machine learning, deep learning, emotional recognition, and natural language application. These articles offer insights into the implications of AI, suggest how nursing education may best respond to emerging AI trends, and provide the authors' perspectives on nursing education reform. The editor hopes readers will be inspired to explore new concepts, gain a deeper understanding of the application and significance of AI, and apply AI to address clinical and educational challenges to foster competent nursing professionals for tomorrow.

Combined aromatase, CDK4/6 and PI3K blockade using letrozole/abemaciclib/LY3023414 in endometrial cancer.

Several lines of preclinical evidence indicate that combining PI3K and CDK4/6 inhibitors may further enhance the efficacy of hormonal therapy by overcoming de novo and acquired resistance to PI3K and CDK4/6 blockade. We evaluated the combination of abemaciclib, letrozole and LY3023414 (an orally available, selective inhibitor of the class I PI3K isoforms and mTORC1/2) in recurrent endometrial cancer (EC). This study was terminated prematurely after 5 patients initiated protocol therapy due to discontinuation of further development of LY3023414. We report our findings from these patients, including one with recurrent endometrioid EC with AKT1, CTNNB1 and ESR1 hotspot mutations who had previously progressed through letrozole/everolimus and achieved a partial response to letrozole/abemaciclib/LY3023414.

Standardized patients' experiences of portraying characters in difficult communication scenarios: Narrative inquiry.

BACKGROUND: There are limited studies that explored the preparation and challenges faced by standardized patients (SPs) in portraying characters in difficult communication scenarios, and the strategies used to overcome these challenges. The purpose of this study was to understand the experience of SPs in interpreting difficult communication situations and the learning needs of performing similar scenarios. And it allows the researchers to explore the meaning, beliefs, values, and aspiration associated with their role as SPs. The findings could shade light on the significance of their experiences and provide valuable insights for the development of future SP training programs. METHODS: The design of this study is framed by a narrative inquiry, using semi-structured guidelines to conduct in-depth interviews with 11 SPs who have participated in the performances of difficult communication situations. Research data were analyzed by Polkinghorne narrative analysis, and Riessman's four criteria were used to establish rigor. RESULTS: Analysis revealed the following five themes: scenarios to real life connections, process of preparing for a performance, methods to detach from character, obtaining unexpected rewards, and needs for performance training. There are two to three subthemes that are subsumed under each theme. CONCLUSIONS: To strengthen training in difficult communication for healthcare professionals, the use of SPs to interpret challenging difficult communication scenarios will continue to increase. Educators need to ensure that SPs are fully prepared physically and emotionally before, during and after their performance. Offering of continuing education and training in feedback techniques are crucial to extend the tenure of SPs, reduce their frustration, prevent attrition, and ultimately, reduce training costs. In the future, SP training should also include detachment and feedback techniques to alleviate SPs' stress.

Using "board games" to improve the effectiveness of extracorporeal membrane oxygenation care for nurses in intensive care unit.

AIM: The purpose of this study was to evaluate the effectiveness of ECMO care board games facilitated teaching approach (ECMO care board games) in enhancing ECMO care knowledge, clinical reasoning and learning engagement among intensive care unit (ICU) nurses. BACKGROUND: ECMO is a highly complex, relatively low-incidence, high-risk clinical life support device system used in the intensive care unit (ICU). Its usage has increased nearly tenfold over the past 30 years. Traditionally, ECMO education has been delivered through classroom teaching, which has demonstrated limited effectiveness in promoting nurses' learning engagement, clinical reasoning competency and confidence. The literature suggests that well-designed board games can enhance learning engagement, stimulate higher-level thinking and improve the effectiveness and confidence of nurses' learning. DESIGN: A quasi-experimental study two-group repeated measure design. METHODS: A purposive sample of 73 ICU nurses from two campuses of one medical center was recruited (37 in the experimental group and 36 in the control group). The experimental group received ECMO care training through ECMO care board games facilitated teaching approach, whereas the control group completed the training through a traditional teaching approach. Instruments used for data collection include a demographic information sheet, ECMO Care Knowledge Scale, Clinical Reasoning Scale (Huang et al., 2023) and Learning Engagement Scale (Ciou , 2020). Both groups completed a pre-test before the training, a post-test one week after the training and a second post-test three weeks after the training. RESULTS: Prior to the intervention, there were no significant differences between the two groups in ECMO care knowledge and learning engagement. However, there was a significant difference in clinical reasoning. One week after the intervention, the experimental group demonstrated significantly higher scores in ECMO care knowledge, clinical reasoning and learning engagement than the control group (p <0.01). Three weeks after the intervention, the experimental group showed significantly higher scores in ECMO care knowledge, clinical reasoning and learning engagement (p <0.001). CONCLUSIONS: The content for ECMO care is complex and difficult. Board games can enhance ECMO care knowledge, clinical reasoning and learning engagement. This teaching strategy may be applied to learning challenging subjects in the future to improve learning effectiveness. The clinical reasoning framework is conducive to guiding nurses' learning. In future continuing education, board games designed based on the clinical reasoning framework and tailored to the focus of in-service education can effectively enhance nurses' learning effectiveness.

Training perinatal nurses in palliative communication by using scenario-based simulation: A quasi-experimental study.

AIM: This study aimed to assess the impact of two educational modules on enhancing the communication confidence, competence and performance of perinatal nurses in the context of palliative care. BACKGROUND: Concerns have arisen regarding the preparedness of perinatal nurses in delivering palliative care, especially in terms of deficiencies in communication skills and negative attitudes toward making life-support decisions for parents facing neonates with terminal conditions. Bridging this gap necessitates improved perinatal palliative care education for healthcare providers. Research has shown that simulation-based teaching effectively enhances procedural competence, communication skills and confidence among healthcare professionals. However, comprehensive curricula focusing on perinatal palliative communication remain limited. DESIGN: This study used a quasi-experimental design employing a two-group repeated measure approach. It involved a purposive sample of 79 perinatal nurses from a hospital in northern Taiwan. METHODS: A palliative communication course specifically designed for registered nurses in perinatal units was developed. Participants were allocated to either the experimental group (Scenario-Based Simulation, SBS) or the control group (traditional didactic lecture). Communication confidence and competence were assessed before and immediately after the course through structured questionnaires. Learning satisfaction was collected post-intervention and participants underwent performance evaluation by standardized parents one week later. RESULTS: A significant training gap in palliative care exists among nurses in OB/GYN wards, delivery rooms and neonatal critical care units, highlighting the need for continuing education. All 79 participants completed the training course. Following the intervention, nurses in the SBS group (n=39) exhibited significant improvements in self-reported confidence (p <0.05), competence (p <0.01) and performance (p <0.001) in neonatal palliative communication compared with the traditional didactic lecture group (n=40). The SBS group also received higher satisfaction ratings from nurse learners (p <0.001). CONCLUSIONS: The research findings support scenario-based simulation as a more effective educational approach compared with traditional didactic lectures for enhancing communication confidence and competence. These results were further reinforced by evaluation from standardized patients, highlighting the value of direct feedback in enhancing nurses' performance. Tailoring SBS designs to diverse nursing contexts and incorporating a flipped approach can further enrich the overall learning experience. Given its high effectiveness and positive reception, we recommend integrating this educational module into palliative care training programs for perinatal nurses.

Effectiveness of a multicomponent activity and horticultural intervention for the hospitalized older adults: A randomized controlled trial: Effectiveness of Intervention for the Hospitalized Older Adults.

This study evaluated the effectiveness of different intervention programs in improving function among hospitalized older individuals using the Comprehensive Geriatric Assessment (CGA). A randomized controlled trial consisted of three groups: routine care, horticulture, and multicomponent activities (n = 32 each). Horticultural and multicomponent activity interventions showed beneficial effects on the CGA in hospitalized older individuals, particularly regarding cognitive function and quality-of-life. Additionally, horticultural activities significantly contributed to the perception of older adults' health status. We recommend to select older patients in geriatric wards with long-term hospitalization and adjust the frequency of activities or choose a single intervention program to provide long-term and effective intervention effects.

Device-independent quantum randomness-enhanced zero-knowledge proof.

Zero-knowledge proof (ZKP) is a fundamental cryptographic primitive that allows a prover to convince a verifier of the validity of a statement without leaking any further information. As an efficient variant of ZKP, noninteractive zero-knowledge proof (NIZKP) adopting the Fiat-Shamir heuristic is essential to a wide spectrum of applications, such as federated learning, blockchain, and social networks. However, the heuristic is typically built upon the random oracle model that makes ideal assumptions about hash functions, which does not hold in reality and thus undermines the security of the protocol. Here, we present a quantum solution to the problem. Instead of resorting to a random oracle model, we implement a quantum randomness service. This service generates random numbers certified by the loophole-free Bell test and delivers them with postquantum cryptography (PQC) authentication. By employing this service, we conceive and implement NIZKP of the three-coloring problem. By bridging together three prominent research themes, quantum nonlocality, PQC, and ZKP, we anticipate this work to inspire more innovative applications that combine quantum information science and the cryptography field.

[Development and Validation of the Outpatient Nurses Communication Behavior Inventory].

BACKGROUND: Outpatient clinics in medical centers are the most common location where people seek medical treatment. Because they must provide patients with treatment information in a timely manner, good communication skills are a key competency for outpatient nurses. However, the tools available for communication behavior assessment are general and rarely tailored for outpatient settings. PURPOSE: The purpose was to develop a communication behavior inventory for outpatient nurses and to examine its reliability and validity. METHODS: During phase one, the authors conducted a literature search and synthesis, using the findings to develop the Outpatient Nurses Communication Behavior Inventory. During phase two, two expert validation rounds were conducted to confirm content validity. During phase three, 220 licensed outpatient nurses were recruited from a medical center in northern Taiwan to complete the instrument (December 2018 - January 2019.) The construct validity and internal consistency of the inventory were evaluated. RESULTS: The literature search and synthesis identified six domains of communication, including connect, introduce, communicate, ask, respond, and exit. A total of 25 items were generated. Following the two expert panel validation rounds, the six domains remained but the inventory items were reduced to 21. Both item-content validity index and scale-level content validity index were 1.0. In phase three, the results of the confirmatory factor analysis retained six factors with a total of 16 items. Model three showed that the inventory demonstrated goodness of fit (Χ ² = 155.75, p < .001, RMSEA = .06, GFI = .92, AGFI = .87, NNFI = .97, NFI = .95, Model AIC = 253.75). Internal consistency was demonstrated with a Cronbach's α of .89. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The Outpatient Nurses Communication Behavior Inventory exhibits good reliability and validity and may be used to assess outpatient nurses' communication behaviors and as a basis for education. The six CICARE (connect, introduce, communicate, ask, respond and exit) domains may be utilized to remind outpatient nurses to demonstrate effective communication consistently, promote outpatient nurses' communication with patients, and improve quality of care.

Excessive gestational weight gain and emotional eating are positively associated with postpartum depressive symptoms among taiwanese women.

BACKGROUND: Excessive gestational weight gain and emotional eating may be associated with postpartum depression symptoms. This study was designed to identify how gestational weight gain and eating behaviors are related to postpartum depression (PPD) symptoms among women in Taiwan. METHODS: A cross-sectional study was conducted from March 2022 to October 2022 with 318 postpartum women recruited in Taipei, Taiwan. Gestational weight gain (GWG) for the total pregnancy period was recorded as inadequate, adequate, or excessive, based on the 2009 Institute of Medicine recommendations (IOM), accounting for pre-pregnancy body mass index category. Eating behavior at one month postpartum was measured on a 16-item 5-point Likert scale with three subscales: uncontrolled, restrained, and emotional. Maternal depressive symptoms were measured using the Edinburgh Postnatal Depression Scale with a cutoff score of 13. RESULTS: The prevalence of postpartum depression symptoms (Edinburgh Postnatal Depression Scale ≥ 13) was 23.9% at one month postpartum. Logistic regression analysis revealed that excessive gestational weight gain and emotional eating were positively associated with postpartum depression symptoms at that time. CONCLUSION: Evidence presented here suggests that emotional eating and excessive GWG are associated with PPD symptoms in a Taiwanese population. In addition, it should be a public health priority to ensure a particular focus on mental health during the postpartum period. Healthcare providers should discourage pregnant women from unhealthy eating habits by targeting appropriate GWG and focusing on demand eating to reduce PPD in the postpartum period.

Report on the PET/CT Image-Based Radiation Dosimetry of [18F]FDHT in Women, a Validated Imaging Agent with New Applications for Evaluation of Androgen Receptor Status in Women with Metastatic Breast Cancer.

In a prospective clinical trial, [18F]fluoro-5α-dihydrotestosterone ([18F]FDHT), the radiolabeled analog of the androgen dihydrotestosterone, was used as a PET/CT imaging agent for in vivo assessment of metastatic androgen receptor-positive breast cancer in postmenopausal women. To our knowledge, this article presents the first report of PET/CT image-based radiation dosimetry of [18F]FDHT in women. Methods: [18F]FDHT PET/CT imaging was performed on a cohort of 11 women at baseline before the start of therapy and at 2 additional time points during selective androgen receptor modulator (SARM) therapy for androgen receptor-positive breast cancer. Volumes of interest (VOIs) were placed over the whole body and within source organs seen on the PET/CT images, and the time-integrated activity coefficients of [18F]FDHT were derived. The time-integrated activity coefficients for the urinary bladder were calculated using the dynamic urinary bladder model in OLINDA/EXM software, with biologic half-life for urinary excretion derived from VOI measurements of the whole body in postvoid PET/CT images. The time-integrated activity coefficients for all other organs were calculated from VOI measurements in the organs and the physical half-life of 18F. Organ dose and effective dose calculations were then performed using MIRDcalc, version 1.1. Results: At baseline before SARM therapy, the effective dose for [18F]FDHT in women was calculated as 0.020 ± 0.0005 mSv/MBq, and the urinary bladder was the organ at risk, with an average absorbed dose of 0.074 ± 0.011 mGy/MBq. Statistically significant decreases in liver SUV or uptake of [18F]FDHT were found at the 2 additional time points on SARM therapy (linear mixed model, P < 0.05). Likewise, absorbed dose to the liver also decreased by a small but statistically significant amount at the 2 additional time points (linear mixed model, P < 0.05). Neighboring abdominal organs of the gallbladder wall, stomach, pancreas, and adrenals also showed statistically significant decreases in absorbed dose (linear mixed model, P < 0.05). The urinary bladder wall remained the organ at risk at all time points. Absorbed dose to the urinary bladder wall did not show statistically significant changes from baseline at any of the time points (linear mixed model, P ≥ 0.05). Effective dose also did not show statistically significant changes from baseline (linear mixed model, P ≥ 0.05). Conclusion: Effective dose for [18F]FDHT in women before SARM therapy was calculated as 0.020 ± 0.0005 mSv/MBq. The urinary bladder wall was the organ at risk, with an absorbed dose of 0.074 ± 0.011 mGy/MBq.

Yue-bi-tang attenuates adriamycin-induced nephropathy edema through decreasing renal microvascular permeability via inhibition of the Cav-1/ eNOS pathway.

Edema is one of the most typical symptoms of nephrotic syndrome. Increased vascular permeability makes a significant contribution to the progression of edema. Yue-bi-tang (YBT) is a traditional formula with excellent clinical efficacy in the treatment of edema. This study investigated the effect of YBT on renal microvascular hyperpermeability-induced edema in nephrotic syndrome and its mechanism. In our study, the content of target chemical components of YBT was identified using UHPLC-Q-Orbitrap HRMS analysis. A nephrotic syndrome model was replicated based on male Sprague-Dawley rats with Adriamycin (6.5 mg/kg) by tail vein injection. The rats were randomly divided into control, model, prednisone, and YBT (22.2 g/kg, 11.1 g/kg, and 6.6 g/kg) groups. After 14 d of treatment, the severity of renal microvascular permeability, edema, the degree of renal injury, and changes in the Cav-1/eNOS pathway were assessed. We found that YBT could regulate renal microvascular permeability, alleviate edema, and reduce renal function impairment. In the model group, the protein expression of Cav-1 was upregulated, whereas VE-cadherin was downregulated, accompanied by the suppression of p-eNOS expression and activation of the PI3K pathway. Meanwhile, an increased NO level in both serum and kidney tissues was observed, and the above situations were improved with YBT intervention. It thus indicates YBT exerts therapeutic effects on the edema of nephrotic syndrome, as it improves the hyperpermeability of renal microvasculature, and that YBT is engaged in the regulation of Cav-1/eNOS pathway-mediated endothelial function.

Development and Psychometric Testing of the Clinical Reasoning Scale Among Nursing Students Enrolled in Three Types of Programs in Taiwan.

BACKGROUND: There is no instrument currently available to assess the essential nursing competency of clinical reasoning (CR). PURPOSE: The purpose of this study was to develop and test the psychometric properties of CR assessment instrument appropriate for use with nursing students across different types of programs. METHODS: H. M. Huang et al.'s (2018) Framework of Competencies of Clinical Reasoning for Nursing Students was used to guide this study. Two rounds of Delphi study and confirmatory factor analysis (CFA) were conducted to test content and construct validity. Internal consistency was tested for reliability. RESULTS: The four-domain, 16-item Likert-scale Clinical Reasoning Scale (CRS) was developed. One thousand five hundred four nursing students currently enrolled in three different types of nursing programs completed the CRS. The content validity index was .85-1.0, the CFA indicated goodness of fit, and the Cronbach's α score range was .78-.89. CONCLUSION: The CRS is a valid and reliable tool for assessing CR in nursing students in different types of nursing program.

Impact of Ultrasonography on Chest Compression Fraction and Survival in Patients with Out-of-hospital Cardiac Arrest.

INTRODUCTION: Whether ultrasonography (US) contributes to delays in chest compressions and hence a negative impact on survival is uncertain. In this study we aimed to investigate the impact of US on chest compression fraction (CCF) and patient survival. METHODS: We retrospectively analyzed video recordings of the resuscitation process in a convenience sample of adult patients with non-traumatic, out-of-hospital cardiac arrest. Patients receiving US once or more during resuscitation were categorized as the US group, while the patients who did not receive US were categorized as the non-US group. The primary outcome was CCF, and the secondary outcomes were the rates of return of spontaneous circulation (ROSC), survival to admission and discharge, and survival to discharge with a favorable neurological outcome between the two groups. We also evaluated the individual pause duration and the percentage of prolonged pauses associated with US. RESULTS: A total of 236 patients with 3,386 pauses were included. Of these patients, 190 received US and 284 pauses were related to US. Longer resuscitation duration was observed in the US group (median, 30.3 vs 9.7 minutes, P<.001). The US group had comparable CCF (93.0% vs 94.3%, P=0.29) with the non-US group. Although the non-US group had a better rate of ROSC (36% vs 52%, P=0.04), the rates of survival to admission (36% vs 48%, P=0.13), survival to discharge (11% vs 15%, P=0.37), and survival with favorable neurological outcome (5% vs 9%, P=0.23) did not differ between the two groups. The pause duration of pulse checks with US was longer than pulse checks alone (median, 8 vs 6 seconds, P=0.02). The percentage of prolonged pauses was similar between the two groups (16% vs 14%, P=0.49). CONCLUSION: When compared to the non-ultrasound group, patients receiving US had comparable chest compression fractions and rates of survival to admission and discharge, and survival to discharge with a favorable neurological outcome. The individual pause was lengthened related to US. However, patients without US had a shorter resuscitation duration and a better rate of ROSC. The trend toward poorer results in the US group was possibly due to confounding variables and nonprobability sampling. It should be better investigated in further randomized studies.

A Phase II, Two-Stage Study of Letrozole and Abemaciclib in Estrogen Receptor-Positive Recurrent Endometrial Cancer.

PURPOSE: Estrogen receptor (ER)-positive endometrial cancers (ECs) are characterized by phosphatidylinositol 3-kinase (PI3K) and receptor tyrosine kinase (RTK)/RAS/ß-catenin (CTNNB1) pathway alterations in approximately 90% and 80% of cases, respectively. Extensive cross-talk between ER, PI3K, and RTK/RAS/CTNNB1 pathways leads to both ligand-dependent and ligand-independent ER transcriptional activity as well as upregulation of cyclin D1 which, in complex with cyclin-dependent kinases 4 and 6 (CDK4 and CDK6), is a critical regulator of cell cycle progression and a key mediator of resistance to hormonal therapy. We hypothesized that the combination of the aromatase inhibitor letrozole and CDK4/6 inhibitor abemaciclib would demonstrate promising activity in this setting. METHODS: We conducted a phase II, two-stage study of letrozole/abemaciclib in recurrent ER-positive EC. Eligibility criteria included measurable disease, no limit on prior therapies, and all EC histologies; prior hormonal therapy was allowed. Primary end points were objective response rate by RECIST 1.1 and progression-free survival (PFS) rate at 6 months. RESULTS: At the data cutoff date (December 03, 2021), 30 patients (28 with endometrioid EC) initiated protocol therapy; 15 (50%) patients had prior hormonal therapy. There were nine total responses (eight confirmed), for an objective response rate of 30% (95% CI, 14.7 to 49.4), all in endometrioid adenocarcinomas. Median PFS was 9.1 months, PFS at 6 months was 55.6% (95% CI, 35.1 to 72), and median duration of response was 7.4 months. Most common ≥ grade 3 treatment-related adverse events were neutropenia (20%) and anemia (17%). Responses were observed regardless of grade, prior hormonal therapy, mismatch repair, and progesterone receptor status. Exploratory tumor profiling revealed several mechanistically relevant candidate predictors of response (CTNNB1, KRAS, and CDKN2A mutations) or absence of response (TP53 mutations), which require independent validation. CONCLUSION: Letrozole/abemaciclib demonstrated encouraging and durable evidence of activity in recurrent ER positive endometrioid EC.

[Exploring Significant Predictors of Retention Willingness in Nurses Diagnosed With COVID-19].

BACKGROUND: COVID-19 affected both the physical and mental health of frontline nurses and the stability of the nursing workforce. PURPOSE: This study was designed to explore the influence of demographic variables, physical and mental health status, perceived work stress, and job satisfaction on intention to continue working as nurses among nursing staff who had been infected by COVID-19. METHODS: In this cross-sectional study, an internal online survey was used to collect data from 152 nurses at a hospital in southern Taiwan. The questionnaires in the survey included the Chinese Health Survey Scale, Stress Scale on COVID-19 Patient Care, McCloskey/ Mueller Satisfaction Scale, and Employee Retention Scale. Data analysis was conducted using SPSS/Windows 22.0. RESULTS: The most significant predictors identified included age, seniority, level of education, job satisfaction, physical and mental wellbeing, and work stress. These predictors collectively explained 32% of the total variance in retention willingness (F [18,128] = 4.78, p < .001). Almost half (46.7%; 71/152) of the participants expressed intent to continue working in nursing. Being a senior staff and having a master's degree or higher were positively associated with retention. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The findings may be referenced by healthcare organizations and managers to help healthcare staff gain strength and resilience against future pandemics. Key recommendations include reducing staff work stress, increasing job satisfaction, and facilitating a more equitable life-work balance.
