ABSTRACT
BACKGROUND: In undergraduate nursing grading practice is generally avoided as it is considered educationally flawed.
OBJECTIVES: To test an innovative online grading practice tool (GPT) in undergraduate nurse education. To model the determinants of the final practice grade in four areas of clinical competence and in one cohort analysis the relationship between final practice grade and each area of clinical competence and an OSCE grade.
DESIGN: A cross-sectional study.
PARTICIPANTS: A convenience sample of 782 nursing students from one Higher Education Institution in the North-East of England were included. The sample involved two sequential cohorts of final-year students with 391 students in each cohort.
METHODS: A specifically designed online grading practice tool (GPT) composed of thirty-six objectives equally divided across four areas of clinical competence. The GPT was applied to two consecutive student cohorts on completion of their final practice learning placement.
RESULTS: There was a statistically significant difference in the mean final practice grade between the two cohorts. In the overall sample, regression modelling showed that all four areas of student assessment contributed equally to the final grade. Analysis by cohort showed that in Cohort 1 clinical thinking and professionalism had the most influence on the final grade with person-centered care and patient safety most strongly impacting on the final grades of Cohort 2. In Cohort 2 there is no statistically significant correlation between final practice grade, each area of clinical competence and an OSCE grade.
CONCLUSIONS: Practice learning is fundamental to how students develop professional awareness and learn to nurse. Findings from a novel grading practice tool applied in undergraduate nursing reveal how effectively the tool works. Nurse educators must be responsive to the realities of learning in practice and explore new ways of assessing clinical competence.

ABSTRACT
To characterize the key odorants of floral aroma green tea (FAGT) and reveal its dynamic evolution during processing, the volatile metabolites in FAGT during the whole processing were analyzed by integrated volatolomics techniques, relative odor activity value (rOAV), aroma recombination, and multivariate statistical analysis. The volatile profiles undergone significant changes during processing, especially in the withering and fixation stages. A total of 184 volatile compounds were identified (∼53.26% by GC-MS). Among them, 7 volatiles with rOAV > 1 were identified as characteristic odorants of FAGT, and most of these compounds reached the highest in withering stage. According to the formation pathways, these key odorants could be divided into four categories: fatty acid-derived volatiles, glycoside-derived volatiles, amino acid-derived volatiles, and carotenoid-derived volatiles. Our study provides a comprehensive strategy to elucidate changes in volatile profiles during processing and lays a theoretical foundation for the targeted processing of high-quality green tea.

ABSTRACT
OBJECTIVE: Women are experiencing growing rates of incarceration at twice the pace of that for men. Additionally, one-third will be older than 55 years of age by the end of the decade. Women who are incarcerated experience a higher prevalence of gynecologic malignancies and present with higher stage disease, which may be contributing to the greater mortality from cancer than the age-adjusted US population. Limited access to guideline-recommended screening and prevention and resource limitations across correctional facilities may result in gynecologic cancer disparities. Reasons for delayed gynecologic cancer care in prisons remain underexplored. Therefore, we sought to identify contributors to delayed gynecologic cancer care among women experiencing incarceration.
METHODS: Women at a single tertiary center in the Southeastern U.S. who were incarcerated and were diagnosed with a gynecologic cancer during 2014-2021 were identified in the electronic medical record. Note text was extracted and contributors to delay were identified and categorized using the RADaR method. Descriptive statistics were used to assess quantitative data.
RESULTS: 14 patients were identified with a total of 14,879 text excerpts. Data reduction was performed to identify excerpts that were relevant to the central research question resulting in 175 relevant note excerpts. Delays prior to the tertiary care visit included patient and institutional contributors. Delays during transition from the tertiary center to prison included discharge planning and loss to follow-up during/after incarceration. Transportation, authorization, and restraints were concrete contributors. Abstract contributors included communication, and the patient’s emotional experience.
CONCLUSIONS: We identify myriad contributors to delayed or fractured gynecologic cancer care in women experiencing incarceration. The impact of these issues warrants further study and intervention to improve care.

ABSTRACT
INTRODUCTION: In thyroid eye disease (TED), all ocular components and adnexa such as extraocular muscles, orbital adipose tissues, eyelids, and tear glands could be affected. This study aimed to study the orbital biomechanical parameters in patients with TED, in terms of differences with healthy individuals and correlation with clinical findings, using Corvis ST (CST, Oculus Wetzlar).
MATERIALS AND METHODS: In this study, 26 consecutive patients with TED were recruited. Demographic data were collected, and patients with TED were assessed for exophthalmos, intraocular pressure, and clinical activity score. Biomechanical response parameters of one randomly-chosen eye of each patient, including whole eye movement length (WEMl) and time (WEMt), were evaluated by the CST, and data were compared between patients and age- and gender-matched healthy controls.
RESULTS: The mean age was 39.88 ± 11.61 years old for patients with TED and 34.38 ± 8.57 years old for the healthy subjects. Nine out of 26 patients with TED and nine of 26 healthy individuals were male. The median duration of thyroid disease was 36 (IQR 54) months and the median duration of thyroid ophthalmopathy was 27 (IQR 27) months. Four out of 26 patients (7.7%) had active disease. The mean WEMl was 206.15 ± 61.58 µm in the TED group and 254.23 ± 64.01 μm in the healthy group, the difference of which was statistically significant (p = 0.008). The median of WEMt was 20.90 (1.15) msec in the TED group and 21.45 (0.93) msec in the healthy group (p < 0.001). Also, the mean of WEMl and WEMt were lower in patients with active disease compared to patients with quiescent disease.
CONCLUSION: The CST-derived WEMl was significantly smaller in patients with thyroid eye disease compared to normal subjects. The WEMl and WEMt were relatively shorter in the patients with active TED compared to the patients with quiescent TED, although small numbers of patients with active TED limits took a statistically significant conclusion. WEMl and WEMt might be useful in evaluating the compliance of the orbit in patients with TED.

ABSTRACT
BACKGROUND: Distal radius fracture is one of the most common injuries presented to emergency department and can be presented in any age group. In young patients the most common cause is Road Traffic Accident (RTA), while old patient history of fall is the most common cause. Different surgical options are available to treat this injury. This study aims to compare the outcome of volar buttress plate vs across wrist external fixator for Arbeitsgemeinschaft für Osteosynthesefragen (AO) type C2/C3 fracture of the distal radius.
METHODS: A retrospective comparative study between July 2020 to June 2021 at Ghurki Trust Teaching Hospital was done and a total of 50 patients who underwent surgical intervention for AO C2/C3 fracture of the distal Radius, were included. The follow-up period was 12 weeks. QuickDASH score was used to find out patient’s functional outcomes. Functional outcome was analyzed between the two groups using Mann-Whitney U test, using SPSS version 21.
RESULTS: There was no significant statistical difference between the functional outcome of patients with distal radius fracture treated with across wrist external fixator vs volar buttress plate, in term of QuickDASH score. Furthermore, age and gender also were having no effect on functional outcome in our population.
CONCLUSIONS: Across wrist external fixator is a reasonable option for AO C2/C3 type fractures of the distal radius with comparable results with volar buttress plate. It is the procedure of choice in high volume tertiary care hospitals like Gurki Trust Teaching hospital as it saves time, have similar functional outcome score, no need to re-open for removal of implant, less chances of tendon rupture as compared to volar buttress plate for distal radius fracture.

ABSTRACT
Despite the urgent need for an effective prediction model tailored to individual interests, existing models have mainly been developed for the mean outcome, targeting average people. Additionally, the direction and magnitude of covariates’ effects on the mean outcome may not hold across different quantiles of the outcome distribution. To accommodate the heterogeneous characteristics of covariates and provide a flexible risk model, we propose a quantile forward regression model for high-dimensional survival data. Our method selects variables by maximizing the likelihood of the asymmetric Laplace distribution (ALD) and derives the final model based on the extended Bayesian Information Criterion (EBIC). We demonstrate that the proposed method enjoys a sure screening property and selection consistency. We apply it to the national health survey dataset to show the advantages of a quantile-specific prediction model. Finally, we discuss potential extensions of our approach, including the nonlinear model and the globally concerned quantile regression coefficients model.

ABSTRACT
PURPOSE: Despite Total Knee Arthroplasty (TKA) being one of the most successful procedures for end stage arthritis, nearly 20% of patients undergoing this procedure remain dissatisfied. Various design options have been introduced to reduce this cohort of patients. One such option has been the introduction of the medial congruent (MC) polyethylene design. This study was undertaken to evaluate outcome measures and gait analysis in patients undergoing bilateral single stage TKA where the posterior cruciate ligament (PCL) was retained or excised in contralateral knees.
METHODS: 60 bilateral TKA’s were performed by a single surgeon using a MC design option from July to Sep 2021. The study lots included patients between the ages of 55 and 70 years with fixed varus deformity of degenerative aetiology, and Kellgren Lawrence Grade 3 and 4 radiological changes. Exclusion criteria were previous surgery to the lower extremities, sero positive arthropathies, post traumatic arthritis, valgus deformity, flexion contractures > 20°, and any pre-existing pathology impacting gait, e.g., poliomyelitis, or neuromuscular disorders. The PCL was retained or sacrificed on contralateral sides for the purpose of this study. Functional scores, outcomes and gait analysis on level and gradient walking were evaluated at a follow-up of 18 months.
RESULTS: At 18, months the Range of Motion (ROM) improved from a preoperative value of 97.3 ± 11.5 to 110.3 ± 6.1 on the PCL retained side (MC-PCL) and from 96.5 ± 10.8 to 113 ± 5.8 on the PCL excised side (MC-PCLX). Knee Society Score (KSS-2011) improved from a preoperative value of 21.2 ± 4.5 to 89.8 ± 3.4 at 18 months postoperatively on the MC-PCL side and from 21.5 ± 4 to 88.2 ± 3.7 on the MC-PCLX side. Forgotten Joint Score (FJS-12) was 8.8 ± 0.7 on the MC-PCL side and 8.1 ± 0.9 on the MC-PCLX side 18 months after surgery. Our gait analysis evaluation demonstrated a lower forefoot pressure in the MC-PCL group in comparison to the MC-PCLX group when subjects were made to walk on a 30° upward incline. This difference was found to be statistically significant.
CONCLUSION: In this study, while ROM was greater in the MC-PCLX study lot, patient satisfaction was higher in the MC-PCL study lot. Gait assessment demonstrated lower forefoot pressure while ascending an incline of 30° in the MC-PCL study lot as compared to the MC-PCLX study lot approximating normal gait patterns.

ABSTRACT
To evaluate the clinical efficacy of carbon dioxide laser in the treatment of female stress urinary incontinence and analyze the influencing factors. A total of 46 patients with stress urinary incontinence treated in the Affiliated Hospital of Nantong University from March 2021 to August 2022 were included through strict inclusion criteria and exclusion criteria. All patients were treated with transvaginal carbon dioxide laser therapy, and Patient Global Impression of Change (PGI-C) was used to evaluate patients’ subjective satisfaction after treatment. The efficacy was evaluated by patient’s subjective assessment of leakage, IngelmanSundberg scale, 1-h urine pad test, and international consultation on incontinence questionnaire short form (ICI-Q-SF) before and after treatment, and the adverse reactions after treatment were recorded. The treatment effect was divided into “significant effect group” and “no significant effect group” by subjective satisfaction and post-treatment-related scale evaluation. After laser treatment, patients’ subjective symptom improved, the volume of 1-h urine pad test was reduced, and the ICI-Q-SF score was decreased, and the differences were statistically significant (P < 0.05). There was no significant difference in IngelmanSundberg scale before and after treatment (P = 1.00). Multivariate logistic regression analysis showed that pad test volume was significantly correlated with treatment effect (P = 0.007). Transvaginal carbon dioxide laser is a safe and effective method for the treatment of mild to moderate stress urinary incontinence in females. The less severe the urinary leakage, the better the treatment effect.

ABSTRACT
OBJECTIVE: The study explores the application value of three-dimensional arterial spin labeling magnetic resonance imaging (3D pCASL) in early assessment of radiation encephalopathy (REP) in patients with nasopharyngeal carcinoma (NPC).
METHODS: A retrospective analysis of 39 cases of NPC was performed. Routine enhanced MRI scan and 3D pCASL imaging were used to examine the apparent diffusion coefficient (ADC) and brain blood flow (CBF) before and after treatment with intensity-modulated radiotherapy (IMRT). Dosimetric analysis of irradiation was performed. Receiver operating characteristic curve (ROC) was used to analyze diagnostic performance of two imaging methods.
RESULTS: There was no statistically significant difference between the two methods for the measurement of temporal white matter ADC, but statistically significant difference was found in CBF. 3D pCASL imaging showed more sensitivity, specificity and higher accuracy than conventional MRI enhanced scan in showing REP. The maximum dose of the temporal lobe was at the enhanced area.
CONCLUSION: The present study demonstrates that 3D pCASL scan at month 3 can reflect blood flow perfusion differences in NPC patients after IMRT and can accurately assess the possibility of REP at early stage. Enhanced areas have a higher probability of REP than the surrounding areas.
ADVANCES IN KNOWLEDGE: There is few magnetic resonance angiography studies used to evaluate arterial circulation on its application on potential REP after radiotherapy for NPC. In our study, we evaluate the application value of 3D pCASL in the early assessment of potential REP in patients with NPC after radiotherapy. The study was to provide an improved understanding of the early specific characteristics on MRI imaging and evolution of potential radiation encephalopathy using 3D pCASL technique, which can quantitatively evaluate the changes of blood flow in tissues at early stage and help to diagnose and treat potential radiation encephalopathy as early as possible.
