ABSTRACT

Autonomy in nursing practice is one of the recurring fields in literature of research. For nurses to be autonomous is considered to have a great importance on the quality of healthcare services. This study aimed to examine the validity and reliability of the Turkish version of the Attitude Toward Professional Autonomy Scale for Nurses. This methodological study adopted a descriptive cross-sectional design. The study was done in a secondary care hospital. Sample group includes 199 nurses that work at a secondary care hospitals. It was carried out while culturally adjusted and it also included two-way translations of English version of the Attitude Toward Professional Autonomy Scale for Nurses. To evaluate its validity, LISREL statistics software was used to make confirmatory factor analysis. Internal consistency was evaluated by using Cronbach’s α and total-item correlations. Average age of the sample group was found 28.35 ± 6.16. Confirmatory factor analysis yielded t-scores, which were significant for all the 18 items (p < .05). Fit indices of the model, resemblance rate chi-square statistics were identified as 𝜒 ²/df = 198.01/132 = 1.50. The Cronbach’s alpha of the scale (.918) was indicative of strong internal consistency. The scale demonstrated strong validity and internal consistency. This scale can be used to assess perceptions of nursing practices that enhance the quality of nursing care.

ABSTRACT

BACKGROUND AND PURPOSE: This study is aimed to analyze the validity and reliability of the Individual Workload Perception Scale in Turkish (IWPSTR).

METHODS: Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), reliability analysis, test-retest, and descriptive statistics were used to analyze data. The sample group of the study consisted of 569 medical and surgical clinic nurses working in hospitals.

RESULTS: The content validity index was .983. The factor loadings of the IWPS_TR were between .359 and .875, the variance accounted for in this study was 62.86%. Cronbach’s alpha value was found to be .923 for the IWPS_TR, and between .721 and .937 for its subscales. Test-retest reliability correlation was found .826.

CONCLUSIONS: It was concluded that the Turkish version of IWPS_TR, which includes 29 items and 5 subscales, could also be applied to nurses in Turkey.

ABSTRACT

In order to navigate a complex web of relationships, an individual must learn and represent the connections between people in a social network. However, the sheer size and complexity of the social world makes it impossible to acquire firsthand knowledge of all relations within a network, suggesting that people must make inferences about unobserved relationships to fill in the gaps. Across three studies (n = 328), we show that people can encode information about social features (e.g., hobbies, clubs) and subsequently deploy this knowledge to infer the existence of unobserved friendships in the network. Using computational models, we test various feature-based mechanisms that could support such inferences. We find that people’s ability to successfully generalize depends on two representational strategies: a simple but inflexible similarity heuristic that leverages homophily, and a complex but flexible cognitive map that encodes the statistical relationships between social features and friendships. Together, our studies reveal that people can build cognitive maps encoding arbitrary patterns of latent relations in many abstract feature spaces, allowing social networks to be represented in a flexible format. Moreover, these findings shed light on open questions across disciplines about how people learn and represent social networks and may have implications for generating more human-like link prediction in machine learning algorithms.

ABSTRACT

BACKGROUND AND PURPOSE: We aimed to translate the Comprehensive Score of Financial Toxicity (COST) questionnaire into Arabic and to evaluate its reliability and validity.

METHODS: We applied the four-step translation method and conducted a pilot validation study over 179 medical oncology patients. Reliability was tested using the Cronbach alpha coefficient and test-retest stability. Validity was tested using the correlation with Functional assessment of Cancer Therapy-General score (FACT-G), factorial analysis and the content validity index.

RESULTS: Questionnaire showed high internal consistency and test retest reliability; Cronbach alpha coefficient was 0.77 and Pearson stability coefficient was 0.8. Convergent validity evaluation showed a statistically significant moderate correlation with the FACT-G (r = .42, p = .047). Content validly index was 0.93.

CONCLUSIONS: The Arabic version of COST questionnaire, was a valid and reliable tool that could be used in clinical practice by healthcare providers to evaluate financial toxicity in Arab speaking cancer patients.

ABSTRACT

Septic arthritis is important to consider in any patient who presents with joint pain because it is a medical emergency with an 11% fatality rate. Diagnosis and treatment may improve prognosis; however, many patients do not regain full joint function. In patients with end-stage renal disease (ESRD), immune dysfunction due to uremia and chronic vascular access leads to increased risk of infection. We examined the incidence, risk factors and sequelae of septic arthritis in a cohort of hemodialysis patients. The US Renal Data System was queried for diagnoses of septic arthritis and selected sequelae using International Statistical Classification of Diseases and Related Health Problems-9 and Current Procedural Terminology-4 codes in patients who initiated hemodialysis between 2005 and 2010. Multivariable logistic regression was used to determine potential risk factors for septic arthritis and its sequelae. 7009 cases of septic arthritis were identified, an incidence of 514.8 per 100,000 persons per year. Of these patients, 2179 were diagnosed with a documented organism within 30 days prior to or 14 days after the septic arthritis diagnosis, with methicillin-resistant Staphylococcus aureus infections (57.4%) being the most common. Significant risk factors for septic arthritis included history of joint disease, immune compromise (diabetes, HIV, cirrhosis), bacteremia and urinary tract infection. One of the four sequelae examined (joint replacement, amputation, osteomyelitis, Clostridioides difficile infection) occurred in 25% of septic arthritis cases. The high incidence of septic arthritis and the potential for serious sequelae in patients with ESRD suggest that physicians treating individuals with ESRD and joint pain/inflammation should maintain a high clinical suspicion for septic arthritis.

ABSTRACT

BACKGROUND: First-degree relatives (FDRs) of cancer patients have a high risk of cancer due to a similar lifestyle and genetic predisposition. However, previous studies rarely examined the level of cancer prevention behaviors and screening and affecting factors in cancer patients’ FDRs.

PURPOSE: This study aimed to describe the levels of cancer knowledge, attitudes toward cancer, cancer worry, perceived cancer risk, and cancer prevention behaviors and cancer screening in FDRs of breast and colorectal cancer patients. Moreover, it sought to identify factors affecting cancer prevention behavior and cancer screening.

METHODS: A cross-sectional, descriptive correlational design was used. The study enrolled 138 FDRs of breast and colorectal cancer patients. Participants completed self-administered questionnaires at a tertiary hospital in Seoul, Korea. Descriptive statistics, frequencies, chi-square test, independent t test, one-way analysis of variance (ANOVA), Pearson’s correlation, multiple regression, and logistic regression were performed for data analysis.

RESULTS: The levels of perceived cancer risk, cancer knowledge, attitude toward cancer, and cancer prevention behaviors were moderate, while the level of cancer worry was high. Ninety-two participants reported having undergone cancer screenings, but the types of screening were not associated with their family history. Age, gender, and attitude toward cancer affected cancer prevention behaviors. The cancer screening rate was higher in older participants, in women, and in patients’ FDRs with a longer cancer diagnosis.

IMPLICATIONS FOR PRACTICE: Attitude was the modifiable factor for cancer prevention behaviors. Nurse-led educational and counseling interventions should be developed to improve attitude toward cancer among FDRs of cancer patients.

ABSTRACT

PURPOSE: MPS1 kinase inhibitor, BAY 1217389 (BAY) synergizes with paclitaxel. This phase 1 study assessed the combination of BAY with paclitaxel using a novel randomized continuous reassessment method (rCRM) to improve dose determination.

EXPERIMENTAL DESIGN: Patients with solid tumors were randomized to receive oral BAY (BID 2‑days‑on/5‑days‑off) with weekly paclitaxel (90 mg/m²) or paclitaxel monotherapy in cycle 1. Dose escalation was guided by CRM modeling. Primary objectives were to assess safety, establish the maximum tolerated dose (MTD) of BAY and to evaluate the pharmacokinetic profiles for both compounds. Simulations were performed to determine the contribution of the rCRM for dose determination.

RESULTS: In total, 75 patients were enrolled. The main dose limiting toxicities were hematologic toxicities (55.6%). The MTD of BAY was established at 64 mg BID with paclitaxel. Inclusion of a control arm enabled the definitive attribution of grade {greater than or equal to}3 neutropenia to higher BAY exposure (AUC_0-12 (P< .001)). After determining the MTD, we included nineteen breast cancer patients at this dose for dose expansion. Other common toxicities were nausea (45.3%), fatigue (41.3%) and diarrhea (40.0%). Overall confirmed responses were seen in 31.6% of evaluable patients. Simulations showed that rCRM outperforms traditional designs in determining the true MTD.

CONCLUSIONS: The combination of BAY with paclitaxel was associated with considerable toxicity without a therapeutic window. However, the use of the rCRM design enabled us to determine the exposure-toxicity relation for BAY. Therefore we propose that the rCRM could improve dose determination in phase I trials that combine agents with overlapping toxicities.

ABSTRACT

BACKGROUND: Miscommunication during clinical handover can lead to partial information transfer and healthcare provider dissatisfaction. We hypothesised that a quality improvement project to standardise the cardiovascular intensive care unit (CVICU) handover could improve healthcare provider satisfaction and reduce information omission.

METHODS: After institutional review board approval, the operating room (OR) to CVICU handover was audited prior, post and 1 year after standardisation implementation. The medical information transferred, healthcare provider participation and satisfaction, and patient outcome data were collected. Additionally, surveys were sent to the OR and CVICU staff by email.

RESULTS: There were 68 handover processes observed. The odds of greater satisfaction with handover for providers were 18 times higher with the process post implementation (p<0.0001) and 26 times higher 1 year after implementation (p<0.0001). There was statistically significant difference between intensive care unit resident presence (45% vs 76% vs 91%, p=0.004), surgical faculty presence (10% vs 36% vs 45%, p=0.034) and surgical fellow presence (15% vs 64% vs 62%, p=0.001) between the three time periods. More information related to the surgeon (5% vs 52% vs 27%, p=0.002), the medical history (65% vs 96% vs 91%, p=0.014) and the cardiopulmonary bypass (47% vs 88% vs 76%, p=0.017) was conveyed. The duration of mechanical ventilation was shorter after implementation (2.2±2.6 days vs 1.2±1.9 days vs 0.5±1.2 days, p=0.026).

CONCLUSIONS: One year after the OR to CVICU standardised handover implementation, the healthcare provider satisfaction remained increased, more team members participated and the information transfer increased. Although some clinical outcomes improved, further studies are recommended to prove causality.

ABSTRACT

Background Up to 70% of patients with ANCA-associated vasculitis (AAV) develop glomerulonephritis, with 26% progressing to ESKD. Diagnostic-grade and noninvasive tools to detect active renal inflammation are needed. Urinary soluble CD163 (sCD163) is a promising biomarker of active renal vasculitis, but a diagnostic-grade assay, assessment of its utility in prospective diagnosis of renal vasculitis flares, and evaluation of its utility in proteinuric states are needed. Methods We assessed a diagnostic-grade urinary sCD163 assay in (1) a real-world cohort of 405 patients with AAV and 121 healthy and 488 non-AAV disease controls; (2) a prospective multicenter study of 84 patients with potential renal vasculitis flare; (3) a longitudinal multicenter cohort of 65 patients with podocytopathy; and (4) a cohort of 29 patients with AAV (with or without proteinuria) and 10 controls. Results We established a diagnostic reference range, with a cutoff of 250 ng/mmol for active renal vasculitis (area under the curve [AUC], 0.978). Using this cutoff, urinary sCD163 was elevated in renal vasculitis flare (AUC, 0.95) but remained low in flare mimics, such as nonvasculitic acute kidney injury. Urinary sCD163’s specificity declined in AAV patients with nephrotic-range proteinuria and in primary podocytopathy, with 62% of nephrotic patients displaying a “positive” urinary sCD163. In AAV patients with significant proteinuria, urinary sCD163 normalization to total urine protein rather than creatinine provided the greatest clinical utility for diagnosing active renal vasculitis. Conclusions Urinary sCD163 is elevated in renal vasculitis flare and remains low in flare mimics. Nonspecific protein leakage in nephrotic syndrome elevates urinary sCD163 in the absence of glomerular macrophage infiltration, resulting in false-positive results; this can be corrected with urine protein normalization.

ABSTRACT

The combination of ipilimumab plus nivolumab (I+N) has greatly improved outcomes in patients with intermediate or poor-risk untreated metastatic renal cell carcinoma (mRCC). However, little is known about the outcomes of patients with brain metastasis (BrM) treated with I+N. A search was performed to retrospectively identify all patients with mRCC treated with I+N in the Duke Cancer Institute and the Cleveland Clinic Taussig Cancer Center, followed by a chart review. Patients were included if they had BrM at the time of I+N initiation. Cohort characteristics are summarized with descriptive statistics. Kaplan-Meier method was used to estimate overall survival (OS) and global, intracranial, and extracranial progression-free survival (PFS) for the cohort and log rank test was used to compare OS and PFS between patient groups. Radiographic response was categorized by RECIST. Fisher’s exact test was used to correlate patient factors with radiographic response. From October 2017 to December 2020, 19 patients with BrM received I+N for mRCC with a median follow-up time of 27.1 months (range 15.0-35.6). By International Metastatic RCC Database Consortium (IMDC) risk criteria, 16% had favorable, 58% had intermediate, and 26% had poor-risk disease. 68% were systemic therapy naïve, and 77% of patients had clear cell histology. 95% had received local CNS directed therapy with surgery, radiotherapy, or both. The objective response rate was 44% (0% complete response) with three of six patients treated in the second line or greater setting experiencing a partial response. The median PFS was 7.6 months (95% CI 5.6 to 14.9). The median extracranial PFS was 8.5 months (95% CI 5.6 to 19.7), and median intracranial PFS was 14.7 months (95% CI 7.2 to not reached). No variables assessed were significantly associated with radiographic response (gender, IMDC risk, presence of bone metastasis, line of therapy, or presence of immune related adverse events). In our retrospective cohort of patients with mRCC with BrM, I+N, in combination with CNS-directed local therapy, appears to have clinical efficacy as previously described with responses seen beyond the first-line setting. Further investigation is warranted in this population given exclusion from prior clinical trials.
