Changes in choroidal thickness quantified by Optical Coherence Tomography across cognitive impairment: data from the NORFACE cohort.

Optical coherence tomography (OCT) enables high-resolution imaging of ocular structures in health and disease. Choroid thickness (CT) is a key vascular retinal parameter that can be assessed by OCT and might be relevant in the evaluation of the vascular component of cognitive decline. We aimed to investigate CT changes in a large cohort of individuals cognitive unimpaired (CU), with mild cognitive impairment due to Alzheimer's (MCI-AD), mild cognitive impairment due to cerebrovascular disease (MCI-Va), Alzheimer's disease dementia (ADD), and vascular dementia (VaD). Clinical, demographical, ophthalmological and OCT data from the Neuro-ophthalmological Research at Fundació ACE (NORFACE) project were analyzed. CT was assessed in the macula across nine Early Treatment Diabetic Retinopathy Study (ETDRS) quadrants, average thickness, total volume, and subfoveal choroidal thickness. Differences of CT among the five diagnostic groups were assessed in a multivariate regression model, adjusting for demographic and cardiovascular risk factors and OCT image quality. A comparison between manual and automatic CT measurements in a subset of participants was also performed. The study cohort comprised 1,280 participants: 301 CU, 196 MCI-AD, 112 MCI-Va, 578 ADD, and 93 VaD. CT was significantly increased in individuals with cognitive impairment compared to those CU, particularly in the VaD and MCI-Va groups and in the peripheral ETDRS regions. No significant differences were found in inner superior, center and subfoveal choroidal thickness. The interaction of sex and diagnosis had no effect in differentiating CT. Mini-Mental State Examination (MMSE) scores were not correlated to CT. Manual and automated CT measurements showed good reliability. Our findings indicated that peripheral choroidal thickening, especially in patients with cerebrovascular disease, may serve as a potential choroidal biomarker for cognitive decline and suggest different pathogenic pathways in AD and VaD. Further research is required to explore CT as a reliable ocular biomarker for cognitive impairment.

Application of clinical thinking training system based on entrustable professional activities in emergency teaching.

Standardized training for resident physicians (STRP) is essential for improving their clinical skills. The standardized training for resident physicians in emergency medicine differs from other disciplines, focusing more on knowledge related to medical emergencies and emergency care skills requiring urgency and real-time response. There are specific differences in knowledge content, teaching methods, curriculum design, and career development compared to other specialties. As a national-level teaching base for emergency medicine, our hospital continuously explores and innovates in teaching models, discovering a model more suitable for emergency medicine. This study summarizes practical experience in teaching and assessment integration (TAA), evaluates teaching training effectiveness with the Clinical Thinking Training System (CTTS), and examines integrating this system with innovative teaching and assessment models' impact on resident physicians' clinical abilities. In our study, we selected residents who rotated in our department from July-December 2023 and randomly divided them into a reform group (n = 106) and a control group (n = 104). The reform group received training using the Clinical Thinking Training System (CTTS) while the control group received standard training consistent with the existing STRP framework. We integrate innovative teaching and assessment (TAA) modelsand theEntrustable Professional Activities(EPAs) scale to assess students' abilities, stratifying by grade level, background, and major to evaluate students' departmental rotation examination (DRE) and EPAs scores. The DRE scores and Mini-CEX scores were significantly higher in the reformed group compared to the control group. The final assessments showed the reform group scored significantly higher in first-case documentation and overall clinical thinking decision-making. Specifically, the reform group had significantly higher scores in first-case documentation for second-year, third-year, undergraduate, and graduate students, and non-emergency specialty students. The clinical thinking decision-making scores of the reform group were significantly higher across different years, specialties, and educational backgrounds. All the EPAs results indicated the CTTS improved treatment decision-making abilities among students with different years of training, educational backgrounds, and specialties. Moreover, the ability for continuous patient management improved to some extent among students in different years and with different educational backgrounds. The integration of innovative teaching and assessment models with the CTTS is more conducive to improving the examination performance and confidence in professional behavior of resident physicians.

Association between functional disability and mental health among Chinese older adults: Examining the moderating effects of social participation and physical exercise.

Functional disability significantly burdens healthcare services, negatively affecting older adults' social interaction and quality of life. This study aims to identify the association between functional disability and mental health, and examine the moderating effects of social participation and physical exercise on the association. The data were drawn from 2018 wave of Chinese Longitudinal Healthy Longevity Survey, and ordinary least squares regression model was exploited to explore the association between functional disability and mental health. Activity of daily living (ADL) disability negatively predicted mini-mental state examination (MMSE) score. Furthermore, social participation and physical exercise moderated the association between ADL disability and MMSE score. The results highlight the importance of social participation and physical exercise for the older adults with ADL disability.

Problem-based learning on the WeChat public platform in radiation oncology residency training programs.

This study explored the effectiveness of a Problem-based Learning (PBL) teaching model on the WeChat public platform for radiation oncology residency training programs. The WeChat PBL program was initiated in 2019. The study recruited student participants, on a voluntary basis, who were in their first and second years of standardized training in radiation oncology. We selected classic and trending issues in radiation oncology as the two main teaching topics. Students in the PBL group searched for relevant literature, summarizing PowerPoint presentations or academic speeches on specific issues published on the professional WeChat public platform after an in-depth review by teachers. The final national standardized training examination scores for resident physicians were used to evaluate teaching effectiveness. The graduation scores of the PBL and non-PBL groups were compared, and a stratified analysis was conducted based on the year of participation to assess the teaching effectiveness of this model. Moreover, questionnaires were administered to evaluate students' experiences. Among the 36 students who joined the study in 2019, 16 (44.0%) voluntarily joined the PBL teaching group. Nine students started teaching PBL in their first year of residency, accounting for 47.4% of that year, and seven started in their second year, accounting for 41.2%. The average graduation scores of the PBL group were superior to those of the non-PBL-focused group for the same grade. The rate of high scores among students in the PBL group (56.3%) was higher than that of students in the non-PBL group (25%). Specifically, first-year residents who joined the PBL group had an average score of 92.3 ± 2.2, significantly higher than their non-PBL counterparts, who scored an average of 88.6 ± 4.6, showing a statistically significant advantage (p = 0.042). All students were satisfied with the PBL WeChat teaching and would recommend the PBL WeChat course to others. The PBL residency teaching model on the WeChat platform improved residency scores and garnered student satisfaction.

Effects of pericapsular nerve group block on early postoperative cognitive function in older people undergoing hip arthroplasty: a randomized controlled clinical trial.

Pericapsular nerve group (PENG) block has emerged as a reliable analgesia technique for hip arthroplasty (HA). However, the effects of PENG block on perioperative neurocognitive disorder (PND) after HA has not yet been assessed. The present study aimed to investigate the effects of PENG block on early postoperative cognitive function in older people undergoing hip arthroplasty. Sixty older patients undergoing HA under spinal anesthesia were randomly assigned to group P (n = 30) receiving PENG block with ropivacaine and patient-controlled intravenous analgesia (PCIA) pump with sufentanil after surgery or group C (n = 30) only receiving PCIA pump with sufentanil after surgery. The primary outcome was the Mini-Mental State Examination (MMSE) score at 7 days postoperatively. Secondary outcomes consisted of the incidence of PND 7 days postoperatively, the static VAS pain scores at 6, 12, 24, and 48h postoperatively; cumulative sufentanil consumption and the requirement of rescue analgesia during the 0-24h period after surgery; quality of recovery-15 (QoR-15) scale scores at 24h postoperatively; and the plasma levels of high mobility group box protein 1 (HMGB1) preoperatively and 1day after surgery, and adverse events. After surgery, the PENG block group had higher MMSE score than the control group at 7 days postoperatively (27.0 ± 1.8 vs. 26.1 ± 1.7, P = 0.048), with a mean difference of 0.9 (95%CI, 0.1-0.9). The incidence of PND at 7 days postoperatively was 6.7% in group P, lower than that of 30% in group C (P = 0.044). In group P, the static VAS scores at 6, 12, and 24h postoperatively were significantly lower than those in group C (all P < 0.05). Compared with group C, the cumulative sufentanil consumption and the number of patients required rescue analgesia during the 0-24h period after surgery were significantly lower in group P (all P < 0.05). The scores of QoR-15 scale were higher in group P at 24h postoperatively than those in group C (P < 0.05). Patients in group P showed lower plasma levels of HMGB1 than group C at 1day after surgery (P < 0.05), and the rate of complications didn't differ between both groups. Older people undergoing HA receiving a PENG block for perioperative analgesia experience improved early postoperative cognitive function, reduced postoperative pain, higher quality of recovery, and less postoperative inflammatory response.

Drug prescriptions in elderly hospitalized patients with cognitive impairment in the Italian Dementia Friendly Hospital project

ObjectiveThe aim of the study was to characterize drug prescription patterns in elderly patients hospitalized in acute wards as a function of cognitive status and staff training.MethodsWe recorded clinical parameters reflecting health status and drug prescriptions at admission, during hospital stay, and at discharge before and after a short staff training on the needs of aged cognitively impaired patients. Participants aged 65 and older had a Mini-Mental State Examination (MMSE) score ≥16. The number of prescriptions, sedative and anticholinergic load, and drug–drug interactions were evaluated. Of the 116 older patients analyzed, 59 patients were cognitively impaired, and 57 were cognitively normal with an MMSE value &amp;gt; 24. Fifty-nine patients (28 CN, 31 CI) were assisted by the hospital health staff after training.ResultsParticipants presented a widespread polypharmacy. Cognitively impaired patients received more prescriptions, more inappropriate prescriptions, had a greater sedative load, and were exposed to more interactions. Staff training had no effect on the prescription pattern.ConclusionThe results suggest that hospitalized cognitively impaired patients are overprescribed psychotropic drugs and have an excessive sedative and anticholinergic load. Interventions designed to improve dementia care practices in health staff that are not also designed to manage drug polypharmacy do not modify prescription patterns.

Performance of ChatGPT in emergency medicine residency exams in Qatar: A comparative analysis with resident physicians

Introduction: The inclusion of artificial intelligence (AI) in the healthcare sector has transformed medical practices by introducing innovative techniques for medical education, diagnosis, and treatment strategies. In medical education, the potential of AI to enhance learning and assessment methods is being increasingly recognized. This study aims to evaluate the performance of OpenAI’s Chat Generative Pre-Trained Transformer (ChatGPT) in emergency medicine (EM) residency examinations in Qatar and compare it with the performance of resident physicians. Methods: A retrospective descriptive study with a mixed-methods design was conducted in August 2023. EM residents’ examination scores were collected and compared with the performance of ChatGPT on the same examinations. The examinations consisted of multiple-choice questions (MCQs) from the same faculty responsible for Qatari Board EM examinations. ChatGPT’s performance on these examinations was analyzed and compared with residents across various postgraduate years (PGY). Results: The study included 238 emergency department residents from PGY1 to PGY4 and compared their performances with ChatGPT. ChatGPT scored consistently higher than resident groups in all examination categories. However, a notable decline in passing rates was observed among senior residents, indicating a potential misalignment between examination performance and practical competencies. Another likely reason can be the impact of the COVID-19 pandemic on their learning experience, knowledge acquisition, and consolidation. Conclusion: ChatGPT demonstrated significant proficiency in the theoretical knowledge of EM, outperforming resident physicians in examination settings. This finding suggests the potential of AI as a supplementary tool in medical education.

Safe Use of Intraspinal Anesthesia in Geriatric Orthopedic Surgery and Its Effect on Coagulation Factors

Objective This study aimed to observe the safe use of intraspinal anesthesia in geriatric orthopedic surgery and its effect on coagulation factors. Methods The anesthesia indices, cognitive functions, hemodynamic indicators, along with coagulation function indices were compared. The duration of anesthesia was compared between the two groups. Adverse reactions occurring in the two groups of patients were compared. Results The time to awaken, time to open eyes, time to the verbal statement, the onset of anesthesia, duration of sensory blockade, and duration of motor nerve blockade were shorter while the duration of analgesia was longer in the observation group than in the control group. The observation group’s postoperative Mini-Mental State Examination scores were higher than those of the control group. Heart rate and mean arterial pressure of the patients in the observation group at 10 min after anesthesia and at the end of surgery were lower versus those in the control group. The observation group had lower levels of von Willebrand factor (%) and fibrinogen at 10 min after anesthesia and at the end of surgery than the control group, and lower levels of the thrombin-antithrombin complex at the end of surgery than the control group. The observation group exhibited a lower incidence of adverse reactions in contrast to the control group. Conclusion The application of intraspinal anesthesia in geriatric orthopedic surgery has a significant and remarkable effect, with less impact on patients’ hemodynamics and postoperative cognitive function, and can improve patients’ blood hypercoagulability.

Mini-mental status examination phenotyping for Alzheimer's disease patients using both structured and narrative electronic health record features.

This study aims to automate the prediction of Mini-Mental State Examination (MMSE) scores, a widely adopted standard for cognitive assessment in patients with Alzheimer's disease, using natural language processing (NLP) and machine learning (ML) on structured and unstructured EHR data. We extracted demographic data, diagnoses, medications, and unstructured clinical visit notes from the EHRs. We used Latent Dirichlet Allocation (LDA) for topic modeling and Term-Frequency Inverse Document Frequency (TF-IDF) for n-grams. In addition, we extracted meta-features such as age, ethnicity, and race. Model training and evaluation employed eXtreme Gradient Boosting (XGBoost), Stochastic Gradient Descent Regressor (SGDRegressor), and Multi-Layer Perceptron (MLP). We analyzed 1654 clinical visit notes collected between September 2019 and June 2023 for 1000 Alzheimer's disease patients. The average MMSE score was 20, with patients averaging 76.4 years old, 54.7% female, and 54.7% identifying as White. The best-performing model (ie, lowest root mean squared error (RMSE)) is MLP, which achieved an RMSE of 5.53 on the validation set using n-grams, indicating superior prediction performance over other models and feature sets. The RMSE on the test set was 5.85. This study developed a ML method to predict MMSE scores from unstructured clinical notes, demonstrating the feasibility of utilizing NLP to support cognitive assessment. Future work should focus on refining the model and evaluating its clinical relevance across diverse settings. We contributed a model for automating MMSE estimation using EHR features, potentially transforming cognitive assessment for Alzheimer's patients and paving the way for more informed clinical decisions and cohort identification.

Changes in brain functional connectivity between on and off states and their relationship with cognitive impairment in Parkinson’s disease

Parkinson’s disease (PD) is characterized by motor and non-motor symptoms. Cognitive decline is crucial in disease progression and affect quality of life; however, their underlying mechanisms in PD remain unclear. We explored the relationship between cognitive impairment and functional connectivity (FC) using resting-state functional magnetic resonance imaging in 26 patients with sporadic PD, focusing on the changes in FC between on and off states. Cognitive function was assessed using the Mini-Mental State Examination (MMSE) score. The correlation between MMSE scores and changes in FC values during on and off states was assessed using Pearson’s correlation coefficient. The correlation between changes in FC during the on and off periods and cognitive function differed for each cognitive function item. MMSE memory scores were positively correlated with FC between the brainstem and the left cerebral hemisphere. MMSE attention scores were positively correlated with FC between the bilateral thalamus and frontal lobes and negatively correlated with FC between the left cerebral hemispheres. These findings may facilitate our understanding of the neural correlates underlying cognitive impairment in PD and help develop treatment strategies to preserve cognitive function.

STAGES OF THE ADMINISTRATIVE PROCEDURE OF STATE ACCREDITATION IN THE FIELD OF HIGHER EDUCATION

The article is devoted to the consideration of the features of the procedural activity carried out within the framework of state accreditation in the field of higher education. The purpose of the article is to identify problematic issues and develop proposals for improving the regulatory acts governing the relevant administrative procedure. The author’s definition of accreditation expertise is formulated as a special procedure for studying educational activities for a specific educational program, conducted by competent experts with special knowledge in the field of education, within the framework of which accreditation indicators and educational activities of the organisation are compared, which allows determining its quality. The need to exclude from the subject of accreditation expertise such indicators as the average score of the unified state examination of students accepted based on its results for training in higher education programmes, as well as the average score of entrance examinations, is substantiated, since these indicators cannot be attributed to the indicators of the quality of educational activities for a specific educational programme of higher school. The integration of the electronic educational environment of educational institutions with the Federal State Information System “the unified identification and authentication system” is proposed. The necessity of specifying individual deadlines within the stage of accreditation expertise is substantiated, which will help to ensure the right of an educational organisation to timely receive the result of the state service for accreditation of educational activities.

Chronic pain in older adults with disabilities is associated with cognitive impairment-a prospective cohort study.

Chronic pain may be an important factor influencing cognitive impairment; however, there is limited research on that link in older adults with disabilities. We aimed to determine the association between chronic pain and cognitive impairment in older adults with disabilities. This 24-month prospective cohort study involved 143 Japanese older adults (≥65 years of age) with long-term care insurance. Chronic pain was defined as pain persisting for ≥3 months, and cognitive impairment was defined as a Mini-Mental State Examination score ≤ 23. We employed logistic regression analysis with chronic pain as the independent variable and cognitive impairment as the dependent variable after propensity score matching (PSM). Sixty-six participants were selected using PSM, and logistic regression analysis showed that chronic pain was significantly associated with cognitive impairment (odds ratio: 4.103, 95% confidence interval: 1.455-11.567, P = 0.008). To prevent cognitive impairment in older adults with disabilities, the management of chronic pain should be considered, as they are related.

Enlarged choroid plexus related to atrophy of hippocampal subfield volumes and glymphatic dysfunction in benzodiazepine use disorder.

The aim of this study was to explore the relationship of choroid plexus (CP) volume with hippocampal subregion volume and glymphatic system in patients with benzodiazepine use disorders (BUD). Eighty-four participants were recruited including 23 patients with BUD, 29 patients with chronic insomnia (CI) and 32 healthy controls (HC). The morphological alterations in CP, hippocampal subfield volumes and diffusion tensor image analysis along the perivascular space (DTI-ALPS) index were compared between the three groups and the relationships between CP volume and hippocampal subfield volumes and the glymphatic system were further investigated. Compared with the HC individuals, the CP volumes augmented and hippocampal subfield volumes reduced in patients with BUD (P < .05) but not in patients with CI (P > .05). In patients with BUD, there were extensive relationships between augmented CP volume and decreased hippocampal subfield volumes (P < .05, r = -0.421--0.513). CP volume was negatively related with the DTI-ALPS index (r = -0.582, P = .004) within the BUD group. In patients with BUD, the volume of bilateral cornu ammonis (CA)1 body, molecular layer (ML) body, hippocampal tail, left CA1 head volumes, right dentate gyrus body volumes, and right CA4 body volumes were positively related with the Montreal Cognitive Assessment scores (P < .05, r = 0.422-0.683). Right CA1 and ML body volumes positively related with the Mini-Mental State Examination scores (P < .05, r = 0.503-0.575). The enlarged CP related to atrophy of hippocampal subfield volumes and the glymphatic system dysfunction were shown in BUD patients.

Predicting Physics Students’ Academic Performance: The Impact of Attitude, Self-Efficacy, and Personality Traits

The study examined the predictive impact of attitude, self-efficacy, and personality traits on the academic performance of high school students in physics. A multistage random sampling technique was used to select 210 research subjects between the ages of 16 and 22 (SD=1.80) from three high schools in the Berekum East Municipality of Ghana. Three standardised questionnaires as primary data sources, namely: Attitude Toward Physics Learning (ATPL), Physics Learning Self-Efficacy (PLSE), and Students’ Personality Trait Inventory (SPTI), and additionally, Students’ Physics Mock Examinations scores as a secondary data source, were used for data collection and analysis through multiple regression. Data collected from respondents were compiled, sorted, edited and coded into the Statistical Package for the Social Sciences (SPSS) version 23. The results revealed a joint impact of 21.100% of the variance in attitude, self-efficacy, and personality traits in predicting the academic performance of students in physics. Furthermore, the multiple regression analysis revealed that student attitudes, self-efficacy, and personality traits significantly impact student academic performance in physics. The analysis further revealed that students’ personality traits best explained students’ academic performance in Physics (β = 0.232, t = 3.423; p &lt; 0.050), followed by self-efficacy (β = 0.192, t = 2.738; p &lt; 0.050), and attitude (β = 0.121, t = 2.011; p &lt; 0.05). Based on the results obtained, the study recommended that physics students in the Berekum East Municipality’s attitudes, self-efficacy, and personality traits should be given greater attention by physics teachers, and other stakeholders because of their positive impact on students’ academic performance in physics.

Deferiprone in Alzheimer Disease

Interventions that substantially slow neurodegeneration are needed to address the growing burden of Alzheimer disease (AD) to societies worldwide. Elevated brain iron observed in AD has been associated with accelerated cognitive decline and may be a tractable drug target. To investigate whether the brain-permeable iron chelator deferiprone slows cognitive decline in people with AD. This phase 2, double-masked, placebo-controlled randomized clinical trial of 12-month duration was conducted at 9 sites in Australia between August 2, 2018, and April 1, 2023. Patients older than 54 years with amyloid-confirmed mild cognitive impairment or early AD (a Mini-Mental State Examination score of 20 or higher) were screened. Randomization was 2:1 and masked to participants and all study staff. Deferiprone 15 mg/kg twice a day or placebo administered orally for 12 months. The primary outcome was a composite cognitive measure assessed at baseline, 6 months, and 12 months using a neuropsychological test battery (NTB) of memory, executive function, and attention tasks. Secondary outcomes included change in brain iron burden measured by quantitative susceptibility mapping (QSM) magnetic resonance imaging (target engagement), brain volume changes (secondary efficacy measure), and adverse events (safety analysis). Of 167 patients screened for eligibility, 81 were included, with 53 randomly assigned to the deferiprone group (mean [SD] age, 73.0 [8.0] years; 29 male [54.7%]) and 28 to the placebo group (mean [SD] age, 71.6 [7.2] years; 17 male [60.7%]); 54 participants completed the study (7 [25.0%] withdrew from the placebo group and 20 [37.7%] from the deferiprone group). In an intention-to-treat analysis, participants in the deferiprone group showed accelerated cognitive decline on the NTB primary outcome (β for interaction = -0.50; 95% CI, -0.80 to -0.20) compared with placebo (change in NTB composite z score for deferiprone, -0.80 [95% CI, -0.98 to -0.62]; for placebo, -0.30 [95% CI, -0.54 to -0.06]). Secondary analysis revealed that this result was driven by worsening performance on executive function tests. The QSM confirmed that deferiprone decreased iron in the hippocampus compared with placebo (change in hippocampal QSM for deferiprone, -0.36 ppb [95% CI, -0.76 to 0.04 ppb]; for placebo, 0.32 ppb [95% CI, -0.12 to 0.75 ppb]; β for interaction = -0.68 [95% CI, -1.27 to -0.09]). Longitudinal hippocampal volume loss was not affected by deferiprone, but exploratory analysis of other brain regions revealed increased volume loss with deferiprone in frontal areas. The frequency of the adverse effect of neutropenia (4 participants [7.5%] in the deferiprone group) was higher than in similar studies (1.6%-4.4%). These trial findings show that deferiprone 15 mg/kg twice a day decreased hippocampal QSM and accelerated cognitive decline in patients with amyloid-confirmed early AD, suggesting that lowering iron with deferiprone is detrimental to patients with AD.

Sensitive written hedgehog PICture Naming and Immediate Recall (PICNIR) as a valid and brief test of semantic and short-term episodic memory for very mild cognitive impairment.

Semantic and short-term episodic memory are impaired in some brain disorders including Alzheimer's disease. Development and validation of an almost self-administered, but cognitively demanding four-minute test identifying very mild cognitive impairment (vMCI). The innovative hedgehog PICture Naming and Immediate Recall (PICNIR) consisted of two parts. The first task was to write down the names of 20 black-and-white pictures to evaluate long-term semantic memory and language. The second task involves immediate recall and writing the names of as many previously named pictures as possible in one minute. The PICNIR is assessed using the number of naming errors (NE) and correctly recalled picture names (PICR). The PICNIR and a neuropsychological battery were administered to 190 elderly individuals living independently in the community. They were divided into those with vMCI (n = 43 with Montreal Cognitive Assessment (MoCA) 24 ± 3 points) and sociodemographically matched cognitively normal (CN) individuals (n = 147 with MoCA 26 ± 3). Both subgroups had predicted mean Mini-Mental State Examination scores of 28-29 points. Compared to CN, vMCI participants made more NE (0.3 ± 0.6 versus 0.6 ± 0.9; p = 0.02) and recalled fewer PICR (8.9 ± 2.2 versus 6.8 ± 2.2; p < 0.000001). Discriminative validity was satisfactory using the area under the ROC curve (AUC): 0.76 for PICR, 0.74 for MoCA, 0.67 for MoCA-five-word recall, and 0.59 for NE. The AUCs of PICR and MoCA were comparable and larger than those of MoCA five-point recall or NE. Logical Memory scores, RAVLT scores, Digit symbol, and animal fluency correlated with PICR. The picture-based PICNIR is an ultra-brief, sensitive cognitive test valid for assessing very mild cognitive impairment. Its effectiveness should be validated for other languages and cultures.

TAVIGER : Intérêt d’une expertise coordonnée gériatrique et cardiologique dans le bilan d’éligibilité des patients âgés à un remplacement valvulaire aortique par voie percutanée

BackgroundTranscatheter aortic valve implantation (TAVI) is the gold standard treatment for aortic stenosis in the elderly. Pre-identification of patients likely to benefit from this procedure remains crucial. A standardised geriatric assessment is used to identify the major geriatric syndromes likely to influence postoperative outcomes. ObjectiveTo identify factors associated with lack of TAVI management and to compare one-year survival in TAVI vs. non-TAVI patients. MethodsRetrospective study, between 2016 and 2020, at the Arras hospital. Patients aged 70 years and older with symptomatic severe aortic stenosis who had undergone geriatric assessment were included. ResultsOne hundred and ninety-two (192) patients, mean age 82.3 years. The 1-year mortality rate was 18% in the TAVI group and 44% in the non-TAVI group (p < 0.001).Parameters associated with no TAVI were Euroscore (ESL) 1 (19.6 ± 10.9 vs. 23.2 ± 13.5, p = 0.020), malnutrition (14% vs. 35%, p = 0.004), walking speed < 0.8 m/s (39% vs. 75%, p = 0.001), Activities of Daily Life (ADL) score (5.4 ± 1 vs. 4.2 ± 1. 6, p < 0. 001) and Instrumental Activities of Daily Life (IADL) score (2.6 ± 1.2 vs. 1.8 ± 1.4, p = 0.002), Mini Geriatric Depression Scale (mini GDS) ≥ 1 (16% vs. 38%, p = 0.045), Mini Mental State Examination (MMSE) score (25.1 ± 3.5 vs. 21.6 ± 4.3 < 0.001). ConclusionsGeriatric syndromes are important determinants of TAVI candidacy. Cardiological surgical risk scores are not effective in discriminating between patients. Coordinated assessment may optimise selection. Therefore, geriatric assessment should be systematically performed as part of the pre-TAVI evaluation.

Diagnostic Accuracy of Combined Measurement of Serum Homocysteine, C-Reactive Protein, and Serum Ferritin in Mild Cognitive Impairments and Alzheimer's Disease.

Evaluation of the diagnostic accuracy of combined detection of serum homocysteine (Hcy), C-reactive protein (CRP), and serum ferritin (SF) levels in patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI). Descriptive study. Place and Duration of the Study: Clinical Laboratory Section, Affiliated Hospital of Hebei University, Baoding, Heibei, China, from May 2022 to June 2023. Data of 120 patients with memory decline were retrospectively collected. They were divided into an MCI group and an AD group. A further 50 healthy participants were used as a normal control (NC) group. Differences in the Hcy, CRP, and SF levels between the three groups were evaluated. The specificity, accuracy, and sensitivity of these three indices in the combined or single diagnosis of AD and MCI were compared. Their associations with the severity of AD and MCI were also compared. The AD group had the highest levels of Hcy, CRP, and SF (18.79 ± 4.50, 6.35 ± 2.04, and 355.69 ± 120.36), followed by MCI (16.75 ± 3.06, 4.58 ± 2.31, and 203.48 ± 12.76), and NC group (14.32 ± 2.06, 2.06 ± 0.76, and 98.46 ± 5.06), with statistically significant differences (all p <0.001). The diagnostic efficacy of AD for CRP was 98.50%, sensitivity was 96.00%, and specificity was 94.00%, which was higher than Hcy and SF. Tested together, the area under the ROC curve was 99.90%, specificity was 98.00%, and sensitivity was 98.00%. The diagnostic efficacy of SF for MCI had sensitivity of 100.00%, and specificity of 100.00%, which was higher than that of Hcy and CRP. When the three were combined for detection, the area under the curve of SF was 100.00%, sensitivity of 100.00%, and specificity of 100.00%. The levels of Hcy, CRP, and SF were positively correlated with the severity of AD (p <0.01), while negatively correlated with the mini-mental state examination (MMSE) score (p <0.01). The combined detection of Hcy, CRP, and SF improved the diagnostic accuracy of comorbid AD and MCI. Homocysteine, C-reactive protein, Cognitive impairment, Serum ferritin, Alzheimer's disease.

The specificity, accuracy, and sensitivity of these three indices in the combined or single diagnosis of AD and MCI were compared. Their associations with the severity of AD and MCI were also compared. The AD group had the highest levels of Hcy, CRP, and SF (18.79 ± 4.50, 6.35 ± 2.04, and 355.69 ± 120.36), followed by MCI (16.75 ± 3.06, 4.58 ± 2.31, and 203.48 ± 12.76), and NC group (14.32 ± 2.06, 2.06 ± 0.76, and 98.46 ± 5.06), with statistically significant differences (all p <0.001). The diagnostic efficacy of AD for CRP was 98.50%, sensitivity was 96.00%, and specificity was 94.00%, which was higher than Hcy and SF. Tested together, the area under the ROC curve was 99.90%, specificity was 98.00%, and sensitivity was 98.00%. The diagnostic efficacy of SF for MCI had sensitivity of 100.00%, and specificity of 100.00%, which was higher than that of Hcy and CRP. When the three were combined for detection, the area under the curve of SF was 100.00%, sensitivity of 100.00%, and specificity of 100.00%. The levels of Hcy, CRP, and SF were positively correlated with the severity of AD (p <0.01), while negatively correlated with the mini-mental state examination (MMSE) score (p <0.01). The combined detection of Hcy, CRP, and SF improved the diagnostic accuracy of comorbid AD and MCI. Homocysteine, C-reactive protein, Cognitive impairment, Serum ferritin, Alzheimer's disease.

Adapting to emergent paradigm shifts: A calibration study among graduating dental students using the new classification of periodontal diseases

IntroductionThe World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions introduced the 2018 Classification. Formulating periodontal diagnosis differs from clinician to clinician and depends on the expertise and competence of the clinician. We aimed to assess calibration levels of periodontal diagnosis based on the 2018 classification among senior-year dental interns at Batterjee Medical College in Saudi Arabia preparing for practice and subsequent graduation. Materials and MethodsIn this preapproved study, 52 senior-year dental students received a two-hour presentation on the 2018 classification by a single teacher, followed by a preliminary exam. One week later, the students were subjected to 12 study cases demonstrating a variety of periodontal and peri-implant disorders with gold standard management, followed by a post-test. Case scenarios with photographs, knowledge cognition, knowledge recall, and case scenarios were the four areas of both exams. Kappa statistics were computed to determine agreement. Statistical significance was set at p < 0.05. ResultsThe total examination score was 12.69 ± 2.74 and 15.12 ± 2.99 (p = 0.001) for the pre- and post-tests, respectively. Furthermore, the difficulty factor and discrimination index increased by 12 % (p = 0.007) and 7 % (p = 0.244), respectively. Finally, the kappa statistic showed moderate agreement at 0.427 (p = 0.002). ConclusionInter-rater agreement with the gold standard increased after training, and this improvement was fairly successful in providing graduating dental students with diagnostic abilities simultaneously with the emergence of a new classification system. A calibration procedure based on a simple feedback approach provided beneficial outcomes.
