RESUMEN
Objective: To summarize the genotype and clinical phenotype of children with WWOX gene related developmental and epileptic encephalopathy (DEE). Methods: Case series studies. The clinical data of 12 children with WWOX gene related DEE who were admitted to the Neurological Department of Children's Medical Center, Peking University First Hospital from June 2019 to December 2023 were analyzed. The children's characteristics of gene variation, clinical phenotype, auxiliary examination results, treatment and prognosis were analyzed. Results: Among 12 children with WWOX gene related DEE, there were 7 boys and 5 girls, the age of seizure onset ranged from 10 days to 6 months (median 1.8 months). Multiple seizure types were observed, including focal seizures in 10 cases, epileptic spasms in 9 cases, tonic seizures in 4 cases, myoclonic seizures in 1 case. Among 12 cases, 9 cases had multiple seizure types. All 12 cases showed microcephaly and global developmental delay. Video electroencephalography showed slowed background activity in 6 cases, hyperarrhythmia in 6 cases, multifocal discharges in 6 cases, and focal discharges in 1 case. Epileptic spasms were detected in 8 cases, tonic seizures in 4 cases and myoclonic seizures in 1 case. Brain magnetic resonance imaging showed bilateral frontotemporal subarachnoid space widening in 5 cases, deep sulci in 3 cases, bilateral ventricular enlargement in 2 cases, callosal hypoplasia in 5 cases, and delayed white matter myelination in 3 cases. The phenotypes of 12 cases were consistent with the diagnosis of DEE, and 8 of them were diagnosed with infantile epileptic spasm syndrome. All the WWOX gene variants in 12 cases were complex heterozygous variants, including 20 variants, 11 variants and 1 large intragenic WWOX gene deletion (p.Ala149Thr, p.Arg156Ser, p.R167Tfs*8, p.Leu186Val, c.605+5G>A, p.Trp218*, p.His263Arg, p.Leu275fs*19*1, p.N285Kfs*10, p.Ser304Tyr, p.Met326Arg, loss1 exon2-8) had not been reported previously. The age of last follow-up ranged from 11 months to 5 years and 3 months. During the follow-up, 1 case died at the age of 1 year and 10 months, 2 cases were seizure-free, and 9 cases still had seizures after multiple anti-seizure medications. Conclusions: The seizure onset age of children with WWOX gene related DEE is usually less than 6 months, and some of them in neonate. The common seizure types include focal seizures and epileptic spasms. Children usually have microcephaly and global developmental delay. WWOX gene related DEE usually has drug refractory epilepsy.

Bacterial communities are highly complex, with interaction networks dictating ecosystem function. Bacterial interactions are constrained by the spatial organization of these microbial communities, yet studying the spatial organization of microbial communities at the single-cell level has been technically challenging. Here, we use the recently developed high-phylogenetic-resolution microbiota mapping by fluorescence in situ hybridization technology to image the gut microbiota at the species and single-cell level. We simultaneously image 63 different bacterial species to spatially characterize the perturbation and recovery of the gut microbiota to ampicillin and vancomycin in the cecum and distal colon of mice. To decipher the biology in this complex imaging data, we developed an analytical framework to characterize the spatial changes of the gut microbiota to a perturbation. The three-tiered analytical approach includes image-level diversity, pairwise colocalization analysis, and hypothesis-driven neighborhood analysis. Through this workflow, we identify biogeographic and antibiotic-based differences in the spatial organization of the gut microbiota. We demonstrate that the cecal microbiota has increased micrometer-scale diversity than the colon at baseline and recovers better from perturbation. Also, we identify potential foundation and keystone species that have high baseline neighborhood richness and that are associated with recovery from antibiotics. Through this workflow, we add a spatial layer to the characterization of bacterial communities and progress toward a better understanding of bacterial interactions leading to improved microbiome modulation strategies. IMPORTANCE: Antibiotics have broad off-target effects on the gut microbiome. When the microbial community is unable to recover from antibiotics, it can lead to increased susceptibility to gastrointestinal infections and increased risk of immunological and metabolic diseases. In this study, we work to better understand how the gut microbiota recovers from antibiotics by employing a recent technology to image the entire bacterial community at once. Through this approach, we characterize the spatial changes in the gut microbiota after treatment with model antibiotics in both the cecum and colon of mice. We find antibiotic- and biogeographic-dependent spatial changes between bacterial species and that many of these spatial colocalizations do not recover to baseline levels even 35 days after antibiotic administration.

The increasing application of virtual surgical planning (VSP) in orthognathic surgery implies a critical need for accurate prediction of facial and skeletal shapes. The craniofacial relationship in patients with dentofacial deformities is still not understood, and transformations between facial and skeletal shapes remain a challenging task due to intricate anatomical structures and nonlinear relationships between the facial soft tissue and bones. In this study, a novel bidirectional 3-dimensional (3D) deep learning framework, named P2P-ConvGC, was developed and validated based on a large-scale data set for accurate subject-specific transformations between facial and skeletal shapes. Specifically, the 2-stage point-sampling strategy was used to generate multiple nonoverlapping point subsets to represent high-resolution facial and skeletal shapes. Facial and skeletal point subsets were separately input into the prediction system to predict the corresponding skeletal and facial point subsets via the skeletal prediction subnetwork and facial prediction subnetwork. For quantitative evaluation, the accuracy was calculated with shape errors and landmark errors between the predicted skeleton or face with corresponding ground truths. The shape error was calculated by comparing the predicted point sets with the ground truths, with P2P-ConvGC outperforming existing state-of-the-art algorithms including P2P-Net, P2P-ASNL, and P2P-Conv. The total landmark errors (Euclidean distances of craniomaxillofacial landmarks) of P2P-ConvGC in the upper skull, mandible, and facial soft tissues were 1.964 ± 0.904 mm, 2.398 ± 1.174 mm, and 2.226 ± 0.774 mm, respectively. Furthermore, the clinical feasibility of the bidirectional model was validated using a clinical cohort. The result demonstrated its prediction ability with average surface deviation errors of 0.895 ± 0.175 mm for facial prediction and 0.906 ± 0.082 mm for skeletal prediction. To conclude, our proposed model achieved good performance on the subject-specific prediction of facial and skeletal shapes and showed clinical application potential in postoperative facial prediction and VSP for orthognathic surgery.

INTRODUCTION: The purpose of this study was to identify predictors of anatomy final course grades from first-year physical therapist students' characteristics and chosen learning strategies, as indicated on the Motivated Strategies for Learning Questionnaire (MSLQ). Identifying factors that contribute to success in content intensive classes may aid in coaching successful learning strategies as students transition from undergraduate coursework to Doctor of Physical Therapy (DPT) programs. REVIEW OF LITERATURE: Previous studies show that first-year graduate students use ineffective learning strategies that are insufficient for graduate-level study. The MSLQ correlates with academic performance at several educational levels. To date, only one study has examined the correlation of MSLQ with physical therapist students' academic performance for an anatomy course. SUBJECTS: Thirty-nine first-year physical therapist students participated in the study (27 from a hybrid program, 12 from a traditional program). METHODS: This study analyzed MSLQ scores for the total instrument, each domain, and each subscale using regression analyses to determine predictors of final anatomy grades. RESULTS: The subscales of Self-Efficacy and Test Anxiety had significant predictive value for anatomy grades (R2 = 0.455, F = 5.203, P = .029). Test Anxiety had an inverse relationship to anatomy grades, meaning lower test anxiety scores correlated with higher anatomy grades. The combination of Self-Efficacy, Test Anxiety, and Critical Thinking subscales resulted in a significant prediction of anatomy grades (R2 = 0.603, F = 6.659, P = .014). DISCUSSION AND CONCLUSION: This study found moderate correlations between MSLQ Motivation subscales and final grades in DPT anatomy classes. Self-Efficacy and Test Anxiety subscales had the strongest correlations and were significantly predictive of anatomy grades. Faculty may benefit from using inventories like the MSLQ for first-year physical therapist students to identify motivational characteristics associated with success and to remediate students' learning strategies to prevent academic failure.

Objective: To study the curative effect of rehmannia glutinosa leaves total glycoside capsules and the role of mitochondrial autophagy on nucleos(t)ide drug-induced renal injury. Methods: Adefovir dipivoxil (ADV) was used to construct a hepatitis B virus (HBV) transgenic mouse model for renal injury. Renal function was measured in each group at one and two weeks of modeling. Mitochondrial autophagy indicators were measured at two weeks of modeling in renal tissue. Transmission electron microscopy was used to detect mitochondrial autophagy phenomena in renal tissue. The model was established for two weeks. Mouse with renal injury were treated with rehmannia glutinosa leaves total glycoside capsules or isotonic saline for eight weeks by intragastric administration. Renal function was measured. Renal tissue morphology was observed. Mitochondrial autophagy indicators were detected in renal tissue. The protective effect of different concentrations of verbascoside (the main active ingredient of rehmannia glutinosa capsule) was observed on HK-2 cell damage induced by ADV. HK-2 cells were divided into control, ADV, and ADV plus verbascoside groups. The effects of verbascoside at different times and concentrations were observed on the HK-2 mitochondrial autophagy indicators. Fifty patients with chronic hepatitis B were collected who presented with renal injury after treatment with nucleos(t)ide analogs. The random number method was used to divide 29 cases into a control group that received conventional treatment. The treatment group of 21 cases was treated with rehmannia glutinosa leaves total glycoside capsules on the basis of the control group. Serum creatinine (Scr) and urinary protein were detected at eight weeks.The χ(2) test or t-test was used for statistical analysis. Results: Compared with the control group, two weeks of modeling in the ADV group induced renal function injury in HBV mice. The expression of autophagy indicators was higher in the renal tissue of the ADV group than that of the control group. Transmission electron microscopy had revealed mitochondrial autophagy in the renal tissue of the ADV group. Compared with the control group, the renal function of HBV mice treated with rehmannia glutinosa leaves total glycoside capsules improved for two months, and the expressions of autophagy indicators were down-regulated.Verbascoside promoted proliferation in ADV-damaged HK-2 cells, and the expression of autophagy indicators was down-regulated compared with the ADV alone group. In 50 patients with renal function injury, the urinary protein improvement was significantly superior in the treatment group than that in the control group, with eighteen and three cases being effective and ineffective in the treatment group and 12 and 17 cases being effective and ineffective in the control group, with a statistically significant difference (χ(2)â =â 9.975 0, Pâ =â 0.001 6). Serum creatinine was decreased in the treatment group compared with the control group, with 11 and 10 cases being effective and ineffective in the treatment group and 12 and 17 cases being effective and ineffective in the control group, with no statistically significant difference (χ(2)â = 0.593 5, Pâ =â 0.441 1). Conclusion: Rehmannia glutinosa leaves total glycoside capsule can improve the nucleos(t)ide drug-induced renal function injury in chronic hepatitis B, possibly playing a role via inhibiting PINK1/Parkin-mediated mitochondrial autophagy.

We present a new measurement of the positive muon magnetic anomaly, a_{µ}≡(g_{µ}-2)/2, from the Fermilab Muon g-2 Experiment using data collected in 2019 and 2020. We have analyzed more than 4 times the number of positrons from muon decay than in our previous result from 2018 data. The systematic error is reduced by more than a factor of 2 due to better running conditions, a more stable beam, and improved knowledge of the magnetic field weighted by the muon distribution, ω[over Ë]_{p}^{'}, and of the anomalous precession frequency corrected for beam dynamics effects, ω_{a}. From the ratio ω_{a}/ω[over Ë]_{p}^{'}, together with precisely determined external parameters, we determine a_{µ}=116 592 057(25)×10^{-11} (0.21 ppm). Combining this result with our previous result from the 2018 data, we obtain a_{µ}(FNAL)=116 592 055(24)×10^{-11} (0.20 ppm). The new experimental world average is a_{µ}(exp)=116 592 059(22)×10^{-11} (0.19 ppm), which represents a factor of 2 improvement in precision.
RESUMEN
BACKGROUND: There is a call to action for health care systems to assess and address burnout among physician trainees. To address this need for programmatic change, we developed a novel initiative to (1) proactively assess trainee burnout and identify drivers and (2) provide resources and recommendations for preventing and reducing burnout. APPROACH: This pilot burnout tracking initiative began in 2020. A two-question burnout survey was disseminated to physician trainees at a hospital devoted exclusively to clinical research. The survey assessed burnout level and drivers of burnout. An algorithm was created to recommend action steps based on trainee responses. Participating training programmes completed a 23-question survey annually to provide information about their trainees and feedback. EVALUATION: Seven of 10 (70%) programmes completed the annual survey in the first year, and 12 of the 15 (80%) programmes completed it the second year. Reported average burnout levels and drivers of burnout varied across programmes; all drivers of burnout were cited as key drivers by at least one programme. Most programmes had conversations with their trainees and found these conversations helpful. All responding programmes who administered the trainee survey felt the initiative improved their ability to track and reduce burnout. IMPLICATIONS: An initiative to systematically track burnout levels and offer targeted interventions was feasible and useful. This project can be a model for institution-wide efforts to address trainee burnout and extend to other clinical health care settings and academic medicine faculty.
RESUMEN
Objective: To explore the intervention effect and mechanism of Dendrobium officinale leaf fermentation liquid on alcoholic hepatitis (AH) mice. Methods: Seventy inbred C57BL/6J male mice aged 6-8 weeks were selected and randomly divided into normal group (NG), model group (MG), liquid feed control group (CG), silybum group (SI), low-dose group (DL), medium-dose group (DM), and high-dose group (DH) of Dendrobium officinale fermentation liquid, with 10 mice in each group. NG group was given common feed, CG group was given control feed (LB alcoholic liquid control feed), SI group was given LB alcoholic liquid feed and silybum by gavage, DL, DM and DH groups were given LB alcoholic liquid feed and 25%, 50% and 100% concentration of Dendrobium officinale leaf fermentation liquid by gavage. An AH model was established by feeding LB alcoholic liquid feed for 8 weeks.At week 8, alanine Transaminase (ALT), triglyceride (TG), transferrin (TRF), interleukin (IL)-6, IL-10, and IL-1ß, tumor necrosis factor-α(TNF-α), interferon-γ(IFN-γ) were detected in eye blood of mice. Liver tissues were stained with HE, Oil Red O, Prussian blue and immunofluorescence ROS. The contents of glutathione(GSH) and malondialdehyde (MDA) in liver tissue homogenate were detected. To analyze the intervention effect and mechanism of Dendrobium officinale leaf fermentation solution on AH mice, the mRNA and protein relative expression levels of adenylate activated protein kinase (AMPK), AMPKß1, phosphorylated AMPKß1 (p-AMPKß1), tumor suppressor gene p53 (p53), solsolic vector family 7 member 11 (SLC7A11), glutathione peroxidase 4 (GXP4) were detected by polymerase chain reaction (PCR) and Western blot. Results: Compared with MG group, the serum ALT and TG levels in the DL, DM, and DH groups were all reduced [ALT: (45.94±19.85), (45.73±22.62), and (41.68±7.13) vs (75.51±17.76) U/L, respectively; TG: (0.90±0.23), (0.69±0.22) and (0.41±0.20) vs (1.28±0.19) mmol/L, respectively, all P<0.05]; IL-6, IL-1ß, TNF-α, IFN-γ were decreased (all P<0.05). The serum TRF and IL-10 levels in the DM and DH groups were increased (all P<0.05). Compared with MG group, the liver tissue MDA of mice in DL, DM and DH groups was decreased [(0.41±0.05), (0.40±0.03), and (0.43±0.14) vs (0.64±0.06)µmol/g, respectively], GSH was increased (all P<0.05). Compared with MG, mRNA expression levels of AMPK (1.36±0.11, 1.61±0.17, 1.68±0.11 vs 0.80±0.12, respectively), SLC7A11 (0.91±0.12, 0.97±0.12, 0.99±0.13 vs 0.60±0.14, respectively) and GPX4 (0.51±0.11, 0.63±0.17, 0.83±0.15 vs 0.42±0.14, respectively) in the liver tissue of DL, DM and DH groups were all increased (all P<0.05). Compared with MG group, DL, DM and DH groups showed the relative expression levels of AMPKß1, p-AMPKß1, SLC7A11 and GPX4 were increased in the liver tissue of mice, while the relative expression levels of p53 protein were decreased (all P<0.05). Compared with MG group, DL, DM and DH groups reduced the degree of hepatic steatosis and inflammation in the lobules, while the iron and ROS staining in the liver tissue became lighter. Conclusion: Dendrobium officinale leaf fermentation liquid can alleviate the severity of AH in mice, and its mechanism may be related to the up-regulation of AMPK to inhibiting the p53/SLC7A11/GPX4 mediated Ferroptosis pathway.

OBJECTIVE: This study aimed to investigate the effect of parecoxib sodium combined with perioperative psychological nursing on postoperative pain in elderly patients with hip fractures. PATIENTS AND METHODS: 80 elderly patients with hip fractures who received surgical treatment in our hospital were selected as the research subjects. According to the different interventions received by the patients, they were divided into a control group (CG) (n=40) who received intravenous parecoxib sodium intervention before surgery, and an observation group (OG) (n=40) who received perioperative psychological nursing intervention in addition to the intervention received by the CG. The pain status, psychological status, hip joint function, daily living ability level, and quality of life of the two groups were compared. RESULTS: After surgery, the VAS score, SAS score and SDS score of the OG were lower than those of the CG (p < 0.05). After surgery, the Harris score of the OG was higher than that of the CG (p < 0.05). Before surgery, there was no significant difference in the Barthel index and SF-36 score between the two groups (p > 0.05). After surgery, the Barthel index and SF-36 scores of both groups showed a significant improvement compared to before surgery, and the scores in the OG were higher than those in the CG (p < 0.05). CONCLUSIONS: Perioperative psychological nursing combined with preemptive analgesia of parecoxib sodium has a significant positive effect on elderly patients with hip fractures after surgery. The combined nursing intervention can further alleviate postoperative pain, improve patients' psychological status, promote the recovery of hip joint function, and significantly improve the daily living ability and quality of life of patients. The combined intervention plan is worthy of clinical promotion and application.

OBJECTIVE: To explore the differences in type I hypersensitivity-induced inflammatory response among children of different age groups with acute appendicitis. METHODS: We selected children diagnosed with "acute appendicitis" who underwent surgery in the Department of General Surgery of Anhui Provincial Children's Hospital from January 2022 to June 2022 and collected their basic data. We divided them into two groups according to age: the infant group (less than 3 years old) and the pediatric group (3-14 years old). The gender, age, onset time, hospital stay, preoperative white blood cells, percentage of neutrophils, C-reactive protein (CRP), and enzyme-linked immunosorbent assay (ELISA) were collected to determine the levels of immunoglobulin E (IgE), interleukin-4 (IL-4), interleukin-5 (IL-5), interleukin-6 (IL-6), and interleukin-9 (IL-9) in appendicular lavage fluid, and the differences between the two groups were compared. RESULTS: There were 15 children in the infant group and 15 in the pediatric group. There was no significant difference between the two groups with respect to onset time and gender. The hospitalization time in the pediatric group was (5.7 ± 2.1) d, the preoperative white blood cells were (14.3 ± 3.7) × 10^9/mL, neutrophil percentage was (84.5 ± 6.3)%, and CRP was (20.0 ± 17.9) mg/mL. The hospitalization time of the infant group was (8.0 ± 3.1) d, the preoperative white blood cells were (19.0 ± 3.8) × 10^9/mL, neutrophil percentage was (77.8 ± 10.4)%, and CRP was (42.5 ± 25.0) mg/mL. The differences between the two groups were significant. There was no significant difference in IL-5 concentration between the two groups in the appendicular lavage fluid. IgE (610.74 ± 72.56) ng/mL, IL-4 (30.80 ± 12.04) ng/mL, IL-6 (118.09 ± 14.29) ng/mL, IL-9 (133.94 ± 16.00) ng/mL were found in the infant group, and IgE (495.61 ± 95.09) ng/mL, IL-4 (22.68 ± 7.05) ng/mL, IL-6 (98.22 ± 22.18) ng/mL and IL-9 (107.86 ± 27.34) ng/mL were found in the pediatric group, and the differences between the two groups were statistically significant. CONCLUSIONS: The inflammatory response in children with acute appendicitis was associated with type I hypersensitivity-induced inflammatory responses, and the type I hypersensitivity was more intense in children in the lower age group.

AIM: To develop and validate a nomogram model that combines computed tomography (CT)-based radiological factors extracted from deep-learning and clinical factors for the early predictions of immune checkpoint inhibitor-related pneumonitis (ICI-P). MATERIALS AND METHODS: Forty ICI-P patients and 101 patients without ICI-P were divided randomly into the training (n=113) and test (n=28) sets. The convolution neural network (CNN) algorithm was used to extract the CT-based radiological features of predictable ICI-P and calculated the CT score of each patient. A nomogram model to predict the risk of ICI-P was developed by logistic regression. RESULTS: CT score was calculated from five radiological features extracted by the residual neural network-50-V2 with feature pyramid networks. Four predictors of ICI-P in the nomogram model included a clinical feature (pre-existing lung diseases), two serum markers (absolute lymphocyte count and lactate dehydrogenase), and a CT score. The area under curve of the nomogram model in the training (0.910 versus 0.871 versus 0.778) and test (0.900 versus 0.856 versus 0.869) sets was better than the radiological and clinical models. The nomogram model showed good consistency and better clinical practicability. CONCLUSION: The nomogram model that combined CT-based radiological factors and clinical factors can be used as a new non-invasive tool for the early prediction of ICI-P in lung cancer patients after immunotherapy with low cost and low manual input.

Objective: To evaluate the long-term safety,effectiveness,predictability and stability of ICL V4c implantation for moderate to high myopia. Methods: In this retrospective case series study, 95 eyes from 50 patients with moderate to severe myopia who were treated in 2015 underwent central hole type posterior chamber intraocular lens (ICL V4c) implantation at Eye & ENT Hospital of Fudan University. The patients were followed up for a period of five years, during which we assessed various parameters including uncorrected visual acuity (UDVA), corrected visual acuity (CDVA), refractive error, axial length, intraocular pressure, endothelial cell density (ECD), vault, and complications. We used the paired t-test and repeated measures one-way ANOVA in SPSS statistical software to analyze the data. Results: The mean spherical equivalent refraction (SE) decreased significantly from (-12.16±3.04) D preoperatively to (-0.19±0.55) D at one month and (-1.14±0.84) D at five years postoperatively. The safety indices (postoperative CDVA/preoperative CDVA) were 1.24±0.27 and 1.13±0.27, respectively, and the efficacy indices (postoperative UDVA/preoperative CDVA) were 1.14±0.25 and 0.87±0.26 at one month and five years postoperatively. At one month after surgery, 80.00% of the eyes were within ±0.50 D of the expected correction, and 96.84% were within ±1.00 D. There was no significant difference in IOP between preoperative and postoperative measurements. The rate of ECD was 3.87%, and the vault decreased by 106.32 µm at five years postoperatively. Conclusion: ICL V4c implantation is safe and effective with good predictability and stability for long term.

OBJECTIVE: To verify the consistency between the digital manufacturing simple intraoral Gothic arch-tracing device and the traditional intraoral Gothic arch-tracing device in determining the centric relation of complete dentures restoration. METHODS: Ten outpatients with edentulous jaws were selec-ted, and the centric relation of the patients was determined by digital manufacturing of simple intraoral Gothic arch-tracing device (T1) and traditional intraoral Gothic arch-tracing device (T2); the difference of clinical operation time between the two methods was recorded; the upper and lower edentulous jaw plaster models were scanned with two kinds of centric relation, the Standard Triangle Language (STL) files imported into Geomagic studio software to apply the best fitting of multiple points of the both upper jaw models, the fitted STL files imported into the 3 shape viewer software, and the maximum position deviations of the vertical, labial (buccal) and lingual directions of the mandibular midline area and molar areas in T1 and T2 groups measured. During the clinical complete dentures try-in, we observed whether there was midline deviation in the mouth of T1 group and T2 group, and whether the occlusion of posterior teeth was stable or not. RESULTS: The mean time spent on determining the centric relation of T1 and T2 groups was (41.90±2.64) min, (57.50±2.37) min respectively. Paired t test was conducted in the two groups, P < 0.01 with significant statistical difference; The mean maximum position deviation between T1 group and T2 group of the midline mandibular region in labial lingual direction was (0.32±0.14) mm, that was (0.40±0.23) mm in vertical direction; the mean maximum position deviation of molar area in buccal lingual direction was (0.35±0.23) mm and that was (0.33±0.20) mm in vertical direction. In the vertical and horizontal directions, the maximum position deviation of mandibles between group T1 and group T2 was controlled within 0.5 mm. In the process of clinical complete dentures try-in, there was no deviation from the center line of dentures. There was not warping, swinging and other poor stability phenomena in T1 and T2 groups. CONCLUSION: The digital manufacturing of simple intraoral Gothic arch-tracing device can be used to determine the centric relation of complete dentures, which can not only save time of clinical operation, but also ensure the accuracy of the centric relation.

Interprofessional education is expanding and emerging as a focus of health profession education. The development of instruments to identify competency of students is needed to improve interprofessional collaboration in patient care. Our purpose was to investigate the individual Jefferson Teamwork Observation Guide (JTOG) to determine its psychometric properties. Health profession student data (814 surveys) were analyzed using Rasch Modeling to determine the item and person statistics, unidimensionality, scaling performance, and local independence. The psychometric properties of the instrument were strong, but the current model produced a significant ceiling effect. Adaptations to the instrument were recommended to improve the instruments ability to identify competency and provide individual feedback on performance using a Rasch model. The adapted JTOG has strong psychometric properties to help facilitate reflection and to promote collaborative practice competency.

INTRODUCTION: Passing the National Physical Therapy Examination (NPTE) is a necessary step in progressing into a professional career. The purpose of this study was to identify student factors that predicted failure on the first attempt of the NPTE in graduates of a blended Doctor of Physical Therapy (DPT) program. REVIEW OF LITERATURE: Student factors that may affect NPTE outcomes have been studied in traditional physical therapist education programs but have not been studied in blended programs. Blended instruction is a delivery format that combines distance asynchronous learning and face-to-face synchronous learning in a complementary way. SUBJECTS: Two hundred ten graduates from 6 consecutive cohorts of a DPT program taught in a blended format. METHODS: Retrospective observational cohort design. Demographic, preadmission, and in-program academic data and NPTE pass/fail status were collected. Variables were analyzed with forward stepwise logistic regression for their ability to predict first-time NPTE failure. Receiver operating characteristic curves were plotted to determine cut points of predictive variables. RESULTS: Two regression analyses were conducted. First, an analysis of all variables identified 3 significant predictors: comprehensive examination score, cumulative third-year grade point average, and Graduate Record Examination Verbal Reasoning (GRE-V) score, which explained 43.2% of the variance. The second analysis excluded variables occurring late in matriculation to identify early occurring predictors. This yielded 2 early predictive variables, GRE-V score and academic difficulty, which explained 29.5% of the variance. DISCUSSION AND CONCLUSION: To our knowledge, this is the first study of predictors of NPTE outcomes in blended DPT program graduates. Like previous studies, a mix of preadmission and in-program factors predicted first-time NPTE failure. These findings may help inform admissions policies, academic advising processes, and academic warning policies in blended programs. Future research is needed to explore factors unique to blended educational settings and the qualities of the students they attract.

Objective: To analyze the genotypes and clinical phenotypes of patients with epilepsy associated with IQSEC2 gene variants. Methods: The genotypes, seizure types, electroencephalogram, neuroimage of 6 patients with IQSEC2 gene variants in the Department of Pediatrics, Peking University First Hospital from July 2019 to October 2021 were analyzed. Results: There were 5 males and 1 female. Six variants were de novo, including 2 frameshift variants (c.3801_3808dup/p.Q1270Rfs*130, c.1459_1460delAT/p.M487Vfs*2), 2 nonsense variants (c.3163C>T/p.R1055*, c.1417G>T/p.E473*), 1 in-frame deletion (c.2295_2297del/p.N765del) and 1 missense variant (c.2293A>G/p.N765D). Age at seizure onset ranged from 3 months to 2 years and 5 months. Multiple seizure types were observed, including epileptic spasms in 5 patients, focal seizures in 5 patients, tonic seizures in 3 patients, myoclonic seizures in 3 patients, atypical absence seizures in 2 patients and atonic seizures in 2 patients. All 6 patients showed global developmental delay before seizure onset. There were other clinical manifestations, including autistic features in 3 patients, microcephaly in 3 patients, dystonia in 2 patients and binocular esotropia in 1 patient. The electroencephalogram showed slow background activity and hypsarrhythmia in all 6 patients. Brain magnetic resonance imaging showed abnormal in 5 patients and normal in 1 patient. Five patients were diagnosed with infantile spasms. Among them, 4 patients had late-onset infantile spasms. One patient was unclassified developmental epileptic encephalopathy. The age of last follow-up ranged from 3 years and 2 months to 7 years and 2 months. All 6 patients still had seizures after multiple anti-seizure medications. Conclusions: The seizure onset of patients with IQSEC2 gene variants usually begins after 1 year of age. The common seizure types include epileptic spasms and focal seizures. Patients usually have a global developmental delay before seizure onset. IQSEC2 variants could be related to developmental and epileptic encephalopathy, and most patients are diagnosed with late onset infantile spasms. Epilepsy associated with IQSEC2 gene variants is usually refractory.

Objective: To summarize the genetics and clinical phenotypes of epilepsy children with 2q24.3 microdeletion. Methods: All the patients with 2q24.3 microdeletion were retrospectively collected at the Pediatric Department of Peking University First Hospital from March 2017 to July 2022. The features of clinical manifestations, electroencephalogram (EEG), and neuroimaging were analyzed. Results: There were 13 patients with 2q24.3 microdeletion were included. All 13 patients had de novo copy number variation (CNV) with a deletion size ranged 0.18-7.31 Mb. The main pathogenic genes in the region were SCN3A, SCN2A, TTC21B, SCN1A and SCN9A genes. Among the 13 patients, 7 were boys, and 6 were girls. The onset age of epilepsy was 3.3(2.5, 6.0) months. Multiple seizure types were observed, including focal seizures in 13 patients, generalized tonic-clonic seizures (GTCS) in 6 patients, myoclonic seizures in 3 patients, epileptic spasm in 2 patients, and tonic seizures in 2 patients. Seizures were fever sensitivity in 9 patients. Status epilepticus was observed in 6 patients. One case had normal mental motor development and 12 cases had different degrees of developmental delay. Six patients had craniofacial abnormality, 1 had six-finger deformity of the right thumb, and 1 had multiple system abnormalities. EEG showed focal discharge in 3 cases, multifocal discharges in 5 cases, multifocal and generalized discharges in 1 case. Brain magnetic resonance imaging (MRI) showed enlargement of subarachnoid spaces in the frontal and temporal region in 4 patients, enlargement of lateral ventricle in 4 patients and delayed myelination of white matter in 1 patient. Dravet syndrome was diagnosed in 5 cases. The age at the last follow-up were 2.5(1.4,5.5) years, 1 patient was seizure free longer than 1 year, and 12 patients still had seizures. Conclusions: The epilepsy associated with 2q24.3 microdeletion is mainly induced by the deletion of SCN3A, SCN2A and SCN1A genes. The seizure onset age of 2q24.3 microdeletion related epilepsy was in infancy. Multiple seizure types are observed and the common seizure types include focal seizures and GTCS. Most patients have fever sensitivity and status epilepticus. Most patients have developmental delay. The phenotype of patients with deletion of SCN3A and SCN2A gene is more severe than that of patients with deletion of SCN1A gene only.
