from the baseline to 12-month follow-up, especially in physical dimensions. Lower age, hypercholesterolaemia, better physical functioning, and diagnosis of peripheral vascular disease seem to be associated with better QoL. Through the analyses of associated variables, we identified stroke survivors who are more at risk and who need more tailored interventions to improve their physical, psychological, emotional, and social dimensions.
To develop and psychometrically test the Reasoning Skills (ReSki) test assessing undergraduate nursing applicants' reasoning skills for student selection purposes.
A methodological cross-sectional design was applied for the psychometric testing.
The ReSki test was developed as part of a wider electronic entrance examination. The ReSki test included a case followed by three question sections assessing nursing applicants' reasoning skills according to the reasoning process. Item response theory was used for psychometric testing to assess item discrimination, difficulty and pseudoguessing parameters. The ReSki test was taken by 1056 nursing applicants in six Finnish Universities of Applied Sciences (28 May 2019).
In the development process, the expert evaluations indicated acceptable content validity. In the psychometric testing, the test reliability was supported by item variance, the theoretical structure was supported by the correlation coefficients and the applicant mean performance supported an accer student selection processes.
What problem did the study address? The assessment of nursing applicants' reasoning skills is suggested, but there is a lack of admission tools. What were the main findings? The results provided support for the reliability and validity of the ReSki test. Item response theory indicated the need for further item-level improvement. Where and on whom will the research have an impact? The results may benefit higher education institutions and researchers when developing a test and/or student selection processes.
To identify the clinical value of ultrasound radiomic features in the preoperative prediction of tumor stage and pathological grade of bladder cancer (BLCA) patients.
We retrospectively collected patients who had been diagnosed with BLCA by pathology. Ultrasound-based radiomic features were extracted from manually segmented regions of interest. Participants were randomly assigned to a training cohort and a validation cohort at a ratio of 73. Radiomic features were Z-score normalized and submitted to dimensional reduction analysis (including Spearman's correlation coefficient analysis, the random forest algorithm, and statistical testing) for core feature selection. Classifiers for tumor stage and pathological grade prediction were then constructed. Prediction performance was estimated by the area under the curve (AUC) of the receiver operating characteristic curve and was verified by the validation cohort.
A total of 5936 radiomic features were extracted from each of the ultrasound images obtained from 157 patients. The BLCA tumor stage and pathological grade prediction models were developed based on 30 and 35 features, respectively. Both models showed good predictive ability. For the tumor stage prediction model, the AUC was 0.94 in the training cohort and 0.84 in the validation cohort. For the pathological grade model, the AUCs obtained were 0.84 in the training cohort and 0.75 in the validation cohort.
The ultrasound-based radiomics models performed well in the preoperative tumor staging and pathological grading of BLCA. These findings should be applied clinically to optimize treatment and to assess prognoses for BLCA.

Velocity selective arterial spin labeling (VS-ASL) is a promising approach for non-contrast perfusion imaging that provides robustness to vascular geometry and transit times; however, VS-ASL assumes spatially uniform tagging efficiency. This work presents a mapping approach to investigate VS-ASL relative tagging efficiency including the impact of local susceptibility effects on a BIR-8 preparation.
Numerical simulations of tagging efficiency were performed to evaluate sensitivity to regionally varying local susceptibility gradients and blood velocity. Tagging efficiency mapping was performed in susceptibility phantoms and healthy human subjects (N = 7) using a VS-ASL preparation module followed by a short, high spatial resolution 3D radial-based image acquisition. Tagging efficiency maps were compared to 4D-flow, B
, and B
maps acquired in the same imaging session for six of the seven subjects.
Numerical simulations were found to predict reduced tagging efficiency with the combination of high blood ead to complicated signal modulations in both tag and control images and reduced tagging efficiency.
To identify and analyse the cultural attitudes, beliefs and practices of internationally educated nurses towards end-of-life care in the context of cancer.
Cultural heritage shape beliefs and practices about cancer and end of life, which complicates nursing care delivery. While previous studies centred on diverse patients' perspectives and cultural competence of healthcare professionals, little analysis available focusing on the cultural attitudes and beliefs of care providers from diverse backgrounds.
Mixed methods systematic review.
CINAHL, MEDLINE, Embase, PsychINFO and Scopus were searched between January and March 2020. No date limit was applied.
Quality appraisal was conducted using the mixed-method appraisal tool. Convergent segregated synthesis was undertaken. Findings were thematically synthesised with the final synthesis presented narratively.
Seven studies were included three qualitative, two quantitative and two mixed methods. None of the studies focused on the end-of-life care experieflicts experienced by internationally educated nurses.
Stakeholders, including the nursing workforce, need to play an active role in providing a culturally inclusive workplace. Support measures are necessary to reduce the impact of cultural conflicts experienced by internationally educated nurses.
End-stage renal disease (ESRD) and the need for haemodialysis (HD) treatment are increasing. The course of the disease and all the life readjustments needed may generate a multitude of fears in patients and families.
This study aimed to explore the main fears and concerns of patients with ESRD undergoing HD and their family members.
A qualitative study was performed.
Individual semi-structured interviews were conducted with three groups 20 patients, 14 family caregivers and 15 patient-family dyads. Interviews were audiotaped, transcribed verbatim and submitted to thematic analysis.
Five major themes emerged (i) fear of death (fear of earlier death, fear of a sudden death and fear of dying); (ii) fear of problems during HD (fears related to the vascular access, and fear of complications during HD); (iii) concerns related to the disease (fear of loss of autonomy, fears of getting worse, fears related to renal transplantation and concerns about dietary restrictions); (iv) fear about the future; and (v)s, patients, and family members, and the care offered by the dialysis care settings. Moreover, this study highlights the impact this disease has at a familial level. Future family-based interventions should acknowledge possible fears and concerns of this population and integrate them into their programs.Clinicians often examine movement patterns to design hip osteoarthritis (OA) interventions, yet traditional biomechanical analyses only report a single timepoint. Multivariate principal component analysis (MFPCA) analyzes the entire waveform (i.e., movement pattern), which clinicians observe to direct treatment. This study investigated hip OA indicators, by (1) employing MFPCA to characterize variance across the hip, knee, and ankle angles in healthy and early-to-moderate hip OA participants; and (2) investigating relationships between these waveform features and hip cartilage health. Bilateral hip magnetic resonance images from 72 participants with Kellgren-Lawrence grades ranging from 0 to 3 were used to calculate mean T 1ρ and T 2 relaxation times in the femoral and acetabular cartilage. MFPCA was performed on lower-limb gait biomechanics and used to identify primary modes of variation, which were related to T 1ρ and T 2 relaxation times. Here, a MFPC = mode of variation = waveform feature. In the femoral cartilage, transverse plane MFPCs 3 and 5 and body mass index (BMI) was related to T 1ρ , while MFPC 2 and BMI were related to T 2 relaxation times. In the acetabular cartilage, sagittal plane MFPC 1 and BMI were related to T 1ρ , while BMI was related to T 2 relaxation times. Greater internal rotation was related to increased T 1ρ and T 2 relaxation times in the femoral cartilage, while the greater extension was related to increased T 1ρ relaxation times in the acetabular cartilage. This study established a data-driven framework to assess relationships between multi-joint biomechanics and quantitative assessments of cartilage health and identified waveform features that could be evaluated in future hip OA intervention studies.
Previous studies based on small-sample clinical data proved that short-term use of hypoxia-inducible factor prolyl hydroxylase (HIF-PHD) inhibitors increased haemoglobin levels in anaemic patients with chronic kidney disease (CKD). However, these studies reached conflicting conclusions on iron parameters and adverse event profiles. Our meta-analysis aimed to evaluate the long-term efficacy and safety of HIF-PHD inhibitors in renal anaemia.
Randomized controlled trials comparing treatment with HIF-PHD inhibitors versus placebo or erythropoiesis-stimulating agents (ESAs) were thoroughly searched in the PubMed, Embase, Cochrane Library and international clinical trial registries. Meta-analysis was performed on main outcomes with random effects models.
A total of 30 studies comprising 13,146 patients were included. The HIF-PHD inhibitors used included roxadustat, daprodustat, vadadustat, molidustat, desidustat and enarodustat. HIF-PHD inhibitors significantly increased haemoglobin levels in comparison with s (1.31, 1.05 to 1.63).
HIF-PHD inhibitors treatment effectively increased haemoglobin levels and promoted iron utilization in anaemic patients with CKD, and they were well tolerated for long-term use. In order to avoid unfavourable effects of excessive iron consumption, it was appropriate to administer HIF-PHD inhibitors in combination with iron supplements for long-term treatment.

Acanthamoeba keratitis is a sight-threatening infectious disease that is difficult to treat. The aim of this study was to evaluate TONS504 (cationic chlorin derivative photosensitizer)-mediated photodynamic antimicrobial chemotherapy (PACT) in vivo as a potential treatment for Acanthamoeba keratitis.
Acanthamoeba keratitis was induced by soft contact lenses incubated with 1 × 10
/ml Acanthamoeba castellanii, which were placed over debrided corneas with temporary tarsorrhaphy. Thirty-eight male Japanese white rabbits were randomly divided into three groups (normal eye, no treatment, and treatment groups). TONS504 was administered as eye drops at 1 mg/ml, followed by light-emitting diode irradiation after the establishment of keratitis at 7 days after infectious contact lens exposure. All animals were evaluated under a slit-lamp microscope every 3 days for 6 days after the treatment. Clinical scores based on corneal epithelial defects detected by fluorescein staining, stromal opacity edema, and vascular infiltration into the cornea were determined.
