Novel patient-specific helical maxillary distractor: an in vitro feasibility study.

At present, stock linear distractors are used for internal maxillary distraction osteogenesis. However, the authors' research group has demonstrated, through an in silico analysis, that linear distraction leads to bone deformities and malocclusion, whereas helical distraction can yield ideal outcomes. A system for designing and manufacturing custom helical distractors has recently been developed, and the feasibility of these appliances now needs to be assessed. This study was, therefore, conducted to gain an initial insight into their feasibility. The study had two goals. First, it aimed to demonstrate, in an in vitro model, that the novel system of custom helical distraction can produce appropriate clinical outcomes. The second aim was to compare the performance of custom helical distractors with that of stock devices and hybrid devices (i.e., linear appliances that feature patient-specific footplates). Interpreting the results as trends, this study showed that the system of custom helical distraction resulted in in vitro outcomes that were superior to those obtained with stock and hybrid devices.

[Clinical characteristics of posterior malleolus fracture in adults].

Objective: To explore the latest clinical characteristics and development trends of posterior malleolus fracture. Methods: Clinical information of inpatients with posterior malleolus fracture in Shanghai Tongji Hospital and Karamay Central Hospital from January 2014 to December 2022 were reviewed and collected. The imaging data of patients were acquired using the Picture Archiving and Communication Systems. A statistical analysis was performed as to gender, current age, year of admission, injury mechanism, fracture type, and posterior malleolus fracture classification. Moreover, a comparative analysis was conducted on the injury mechanisms and morphological differences of posterior malleolus fracture at different periods, regions, and age groups. Results: A total of 472 patients (210 patients from Shanghai Tongji Hospital and 262 patients from Karamay Central Hospital) with posterior malleolus fracture with a mean age of (48.7±15.6) years were included in this study. The peak of posterior malleolus fracture occurs in the age group of 50-59 years. The injury mechanisms mainly involve low-energy fall and sprain (411 cases, 87.1%), followed by traffic accidents (52 cases, 11.0%), and fall injury from height (9 cases, 1.9%). The number of cases according to different fracture types showed the following descending order: trimalleolar fracture-supination extorsion (335 cases, 71.0%), bimalleolar fracture (60 cases, 12.7%), trimalleolar fracture-pronation extorsion (43 cases, 9.1%), posterior malleolus+tibial shaft fracture (19 cases, 4.0%), simple posterior malleolus fracture (15 cases, 3.2%). The numbers of cases corresponding to the Haraguchi Ⅰ, Ⅱ and Ⅲ type of posterior malleolus fractures was 369 (78.2%), 49 (10.4%), and 54 (11.4%), respectively. The Tongji ⅡA type represented the highest number of cases (249 cases, 52.8%), followed by the ⅡB type (120 cases, 25.4%), Ⅰ type (54 cases, 11.4%), ⅢB type (36 cases, 7.6%), and ⅢA type (13 cases, 2.8%). However, no obvious statistical difference was observed in the injury mechanism, Haraguchi classification, and Tongji classification of posterior malleolus fractures among different years and regions from the year of 2014 to 2022 (all P>0.05). Conclusions: The injury mechanism of posterior malleolus fracture mainly involves low-energy fall and sprain cases. The trimalleolar fracture-supination extorsion, Haraguchi Ⅰ type and Tongji ⅡA type of posterior malleolus fracture are predilection fracture types, and all present an obvious incidence peak in the age group of 50-59 years. There has been no significant change in the development trend of clinical characteristics of posterior malleolus fractures in recent years.

[Clinical features and Y chromosome abnormalities in children with 45, X/46, XY mosaicism].

Objective: To investigate the clinical and genetic characteristics of children with 45, X/46, XY mosaicism. Methods: The retrospective study included 20 children diagnosed with 45, X/46, XY and 45, X/46, X,+mar mosaicism in the First Affiliated Hospital of Zhengzhou University from 2018 to 2022. The clinical features, gonadal pathology, treatment and follow-up were summarized. Genetic tests were performed by SRY gene test, azoospermia factor region (AZF) deletion test, copy number variation-sequencing (CNV-seq). Age at first diagnosis was compared between boys and girls using independent sample t-test. Results: The 20 patients included 3 boys and 17 girls, and the age at first diagnosis were (7.6±5.5) years, it is (2.1±1.9) years in boys, (8.7±5.4) years in girls, significantly younger for boys (t=-3.86, P=0.004). The chief complaint was external genitalia malformation for boys, and short stature (13 cases) and dysplastic external genital for girls (4 cases). Five girls presented with features of Turner syndrome. The gonadal phenotypes included mixed gonadal dysplasia (MGD, 6 cases), complete gonadal dysplasia (CGD, 10 cases), unilateral ovotestis (2 cases), possible ovaries (1 case) and undetermined gonad (1 case). One female with dysplastic genital was reassigned to male, and the gender of the remaining cases remained unchanged. Seven females were treated with recombinant human growth hormone. The height increased by (17±7) cm during the (2.9±1.2) years follow-up. No gonadal malignancy was observed. The karyotype was 45, X/46, XY in 16 cases, and 45, X/46, X,+mar in 4 cases. All of the 4 marker chromosomes were derived from Y chromosome confirmed by CNV-seq. SRY gene was detected in all 20 patients genome, and AZF deletion was found in 7 girls. Conclusions: 45, X/46, XY mosaicism presented with dysplastic external genital or female with remarkable short stature. Gonadal phenotypes included MGD, CGD and ovotestis. AZF microdeletions were found in the majority of female cases.

Helical distraction is superior to linear and circular distraction in mandibular distraction osteogenesis: an in silico study.

Helical mandibular distraction is theoretically better than linear or circular distraction. However, it is not known whether this more complex treatment will result in unquestionably better outcomes. Therefore, the best attainable outcomes of mandibular distraction osteogenesis were evaluated in silico, given the constraints of linear, circular, and helical motion. This cross-sectional kinematic study included 30 patients with mandibular hypoplasia who had been treated with distraction, or to whom this treatment had been recommended. Demographic information and the computed tomography (CT) scans showing the baseline deformity were collected. The CT scans of each patient were segmented and three-dimensional models of the face created. Then, the ideal distraction outcomes were simulated. Next, the most favorable helical, circular, and linear distraction movements were calculated. Finally, errors were measured: misalignment of key mandibular landmarks, misalignment of the occlusion, and changes in intercondylar distance. Helical distraction produced trivial errors. In contrast, circular and linear distractions resulted in errors that were statistically and clinically significant. Helical distraction also preserved the planned intercondylar distance, while circular and linear distractions led to unwanted changes in the intercondylar distance. It is now evident that helical distraction offers a new strategy to improve the outcomes of mandibular distraction osteogenesis.

The effects of computer-aided cognitive rehabilitation combined with virtual reality technology on event-related potential P300 and cognitive function of patients with cognitive impairment after stroke.

OBJECTIVE: The aim of this study was to explore the effects of computer-aided cognitive rehabilitation (CACR) combined with virtual reality (VR) technology on event-related potential P300 and cognitive function in patients with cognitive impairment after stroke. PATIENTS AND METHODS: Clinical data from 94 patients with post-stroke cognitive impairment, admitted to our hospital from January 2020 to March 2023, were retrospectively analyzed. Of them, 45 patients received routine rehabilitation training (Control group), and 49 patients received CACR combined with VR technology (Observation group). Cognitive rehabilitation status, event-related potential P300 examination status, biochemical indices levels, and daily living activity scores of the two groups were evaluated and compared. RESULTS: After treatment, cognitive function significantly improved in the Observation group compared to the Control group. The amplitude of P300 in the Observation group was significantly higher, and the latency was significantly lower compared to the Control group. The levels of brain-derived neurotrophic factor (BDNF) in the Observation group were significantly higher (p<0.05), while the levels of cystatin C (Cys-C) and neuron-specific enolase (NSE) were significantly lower than those in the Control group (p<0.05 each). Patients in the Observation group demonstrated a significantly higher ability to perform daily living activities compared to the Control group (p<0.05). CONCLUSIONS: Compared with conventional rehabilitation training, the combination of CACR and VR technology in the treatment of stroke-induced cognitive impairment is more effective in improving patients' cognitive function, regulating BDNF, Cys-C, and NSE levels, and enhancing patients' ability to perform daily living activities.

Molecular dynamics of interfacial crystallization of dodecane on hydroxylated silica surface impacted by H2O and CO2.

The morphology of dodecane in a nanopore at temperatures typical in exploited or depleted oil reservoirs is investigated using molecular dynamics simulation. The dodecane morphology is found to be determined by interactions between interfacial crystallization and surface wetting of the simplified oil, while "evaporation" only plays a minor role. The morphology changes from an isolated, solidified dodecane droplet to a film with orderly lamellae structures remaining within, and finally to a film containing randomly distributed dodecane molecules, as the system temperature increases. In a nanoslit under the impact of water, since water wins against oil in surface wetting on the silica surface due to electrostatic interaction induced hydrogen bonding between water and the silanol group of silica, the spreading of dodecane molecules over the silica surface is impeded by this water confinement mechanism. Meanwhile, interfacial crystallization is enhanced, leading to always an isolated dodecane "droplet," with crystallization weakening as the temperature increases. Since dodecane is immiscible to water, there is no mechanism for dodecane to escape the silica surface, and the competition of surface wetting between water and oil determines the morphology of the crystallized dodecane droplet. For the CO2-dodecane system in a nanoslit, CO2 is an efficient solvent for dodecane at all temperatures. Therefore, interfacial crystallization rapidly disappears. The competition of surface adsorption between CO2 and dodecane is secondary for all cases. The dissolution mechanism is a clear clue for the fact that CO2 is more effective than water flooding in oil recovery for a depleted oil reservoir.

[Clinical and genetic characteristic in patients with disorders of sex development caused by Y chromosome copy number variant].

Objective: To investigate the clinical phenotype and genetic characteristics of disorders of sex development (DSD) caused by Y chromosome copy number variant (CNV). Methods: A retrospective analysis was performed on 3 patients diagnosed with DSD caused by Y chromosome CNV admitted to the First Affiliated Hospital of Zhengzhou University from January, 2018 to September, 2022. Clinical data were collected. Clinical study and genetic test were performed by karyotyping, whole exome sequencing (WES), low coverage whole genome copy number variant sequencing (CNV-seq), fluorescence in situ hybridization (FISH) and gonadal biopsy. Results: The 3 children, aged 12, 9, 9 years, the social gender were all female, presented with short stature, gonadal dysplasia and normal female external genital. No other phenotypic abnormality was found except for case 1 with scoliosis. The karyotype of all cases were identified as 46, XY. No pathogenic vraiants were found by WES. CNV-seq determined that case 1 was 47, XYY,+Y(2.12) and case 2 was 46, XY,+Y(1.6). FISH concluded that the long arm of Y chromosome was broken and recombined near Yq11.2, and then produced a pseudodicentric chromosome idic(Y). The karyotype was reinterpreted as mos 47, X, idic(Y)(q11.23)×2(10)/46, X, idic(Y)(q11.23)(50) in case 1. The karyotype was redefined as 45, XO(6)/46, X, idic(Y)(q11.22)(23)/46, X, del(Y)(q11.22)(1) in case 2. 46, XY, -Y(mos) was found by CNV-seq in case 3, and the karyotype of 45, XO/46, XY was speculated. Conclusions: The clinical manifestations of children with DSD caused by Y chromosome CNV are short stature and gonadal dysgenesis. If there is an increase of Y chromosome CNV detected by CNV-seq, FISH is recommended to classify the structural variation of Y chromosome.

[Allogeneic hematopoietic stem cell transplantation in acute leukemia patients with the SET-NUP214 fusion gene: Efficacy and survival analysis].

Objective: To investigate the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for patients with acute leukemia who are positive for the SET-NUP214 fusion gene (SET-NUP214+AL). Methods: This was a retrospective case series study. Clinical data of 18 patients with SET-NUP214+AL who received allo-HSCT in the First Affiliated Hospital of Soochow University and Soochow Hongci Hematology Hospital from December 2014 to October 2021 were retrospectively analyzed to investigate treatment efficacy and prognosis. The Kaplan-Meier method was used for survival analysis. Results: Of the 18 patients, 12 were male and 6 were female, and the median age was 29 years (range, 13-55 years). There were six cases of mixed phenotype acute leukemia (three cases of myeloid/T, two cases of B/T, one case of myeloid/B/T), nine cases of acute lymphoblastic leukemia (ALL) (one case of B-ALL and eight cases of T-ALL), and three cases of acute myeloid leukemia. All patients received induction chemotherapy after diagnosis, and 17 patients achieved complete remission (CR) after chemotherapy. All patients subsequently received allo-HSCT. Pre-transplantation status: 15 patients were in the first CR, 1 patient was in the second CR, 1 was in partial remission, and 1 patient did not reach CR. All patients were successfully implanted with stem cells. The median time of granulocyte and platelet reconstitution was +12 and +13 days, respectively. With a median follow-up of 23 (4-80) months, 15 patients survived, while 3 patients died. The cause of death was recurrence of SET-NUP214+AL after transplantation. After allo-HSCT, 5 patients relapsed. The estimated 3-year overall survival (OS) and relapse-free survival (RFS) rates were 83.3%±15.2% and 55.4%±20.7%, respectively. Among the 15 patients who achieved CR before transplantation, there was no significant difference in OS and RFS between haploidentical HSCT and matched sibling donor HSCT (all P>0.05). Conclusions: Allo-HSCT can improve the prognosis and long-term survival rate of patients with SET-NUP214+AL. Disease recurrence is the most important factor affecting long-term survival.

Search for Cosmic-Ray Boosted Sub-GeV Dark Matter Using Recoil Protons at Super-Kamiokande.

We report a search for cosmic-ray boosted dark matter with protons using the 0.37 megaton×years data collected at Super-Kamiokande experiment during the 1996-2018 period (SKI-IV phase). We searched for an excess of proton recoils above the atmospheric neutrino background from the vicinity of the Galactic Center. No such excess is observed, and limits are calculated for two reference models of dark matter with either a constant interaction cross section or through a scalar mediator. This is the first experimental search for boosted dark matter with hadrons using directional information. The results present the most stringent limits on cosmic-ray boosted dark matter and exclude the dark matter-nucleon elastic scattering cross section between 10^{-33}cm^{2} and 10^{-27}cm^{2} for dark matter mass from 1 MeV/c^{2} to 300 MeV/c^{2}.

Helical distraction is superior to linear distraction in maxillary distraction osteogenesis: an in silico study.

This in silico kinematic study was performed to evaluate the best attainable outcomes of maxillary distraction osteogenesis given the constraints of linear and helical motion. The study sample included the retrospective records of 30 patients with maxillary retrusion who had been treated with distraction or had been recommended this treatment. The primary outcomes were the errors of linear and helical distraction. The study measured two types of error: misalignment of key upper jaw landmarks and misalignment of the occlusion. Concerning the misalignment of key landmarks, the median misalignments resulting from helical distraction were minimal; the interquartile ranges were also minimal. The median misalignments and interquartile ranges that resulted from linear distraction were significantly larger. Regarding the occlusal misalignments, helical distraction produced minor occlusal misalignments, while linear distraction produced significantly larger errors. The results of this study confirmed that helical motion is the ideal motion for LeFort I distraction.

Prognostic value of combined pre- and postoperative albumin-to-alkaline phosphatase ratio for patients with hepatocellular carcinoma undergoing trans-catheter chemoembolisation.

AIM: To reveal the prognostic value of the postoperative and dynamic albumin-to-alkaline phosphatase ratio (AAPR) in hepatocellular carcinoma (HCC) patients undergoing trans-catheter chemoembolisation (TACE). MATERIALS AND METHODS: In total, 545 HCC patients undergoing initial TACE were enrolled into the study. The receiver operating characteristic (ROC) curve was plotted to determine the best cut-off for AAPR. Univariate and multivariate Cox regression analyses were used to confirm the independent prognostic effect of AAPR on overall survival (OS). The predictive performance of AAPR was assessed by ROC curves, concordance index (C-index), and Akaike information criterion (AIC), and was compared to existing liver function assessment systems. RESULTS: The optimal cut-off value for the AAPR was 0.26. Elevated AAPR (>0.26) was associated with a low risk of death after adjustment whether before (HR: 0.53; 95% CI: 0.4-0.69) or after (HR: 0.64; 95% CI: 0.43-0.95) TACE treatment. The combined pre- and postoperative AAPR showed much better performance in ROC curve (1-, 3-, and 5-year AUCs: 0.69, 0.71, 0.69), C-index (0.65; 95% CI: 0.59-0.72) and AIC analyses than pre-AAPR and post-AAPR alone or liver function assessment systems. CONCLUSION: This study demonstrated both preoperative and postoperative AAPR were independent prognostic factors for HCC patients undergoing TACE. In addition, the combined pre- and post-AAPR showed better predictive performance than pre-AAPR and post-AAPR alone or liver function assessment systems.

Clinical feasibility of deep learning-based automatic head CBCT image segmentation and landmark detection in computer-aided surgical simulation for orthognathic surgery.

The purpose of this ambispective study was to investigate whether deep learning-based automatic segmentation and landmark detection, the SkullEngine, could be used for orthognathic surgical planning. Sixty-one sets of cone beam computed tomography (CBCT) images were automatically inferred for midface, mandible, upper and lower teeth, and 68 landmarks. The experimental group included automatic segmentation and landmarks, while the control group included manual ones that were previously used to plan orthognathic surgery. The qualitative analysis of segmentation showed that all of the automatic results could be used for computer-aided surgical simulation. Among these, 98.4% of midface, 70.5% of mandible, 98.4% of upper teeth, and 93.4% of lower teeth could be directly used without manual revision. The Dice similarity coefficient was 96% and the average symmetric surface distance was 0.1 mm for all four structures. With SkullEngine, it took 4 minutes to complete the automatic segmentation and an additional 10 minutes for a manual touchup. The results also showed the overall mean difference between the two groups was 2.3 mm for the midface and 2.4 mm for the mandible. In summary, the authors believe that automatic segmentation using SkullEngine is ready for daily practice. However, the accuracy of automatic landmark digitization needs to be improved.

Cold stress triggers freezing tolerance in wheat (Triticum aestivum L.) via hormone regulation and transcription of related genes.

Low temperatures limit the geographic distribution and yield of plants. Hormones play an important role in coordinating the growth and development of plants and their tolerance to low temperatures. However, the mechanisms by which hormones affect plant resistance to extreme cold stress in the natural environment are still unclear. In this study, two winter wheat varieties with different cold resistances, Dn1 and J22, were used to conduct targeted plant hormone metabolome analysis on the tillering nodes of winter wheat at 5 °C, -10 °C and -25 °C using an LC-ESI-MS/MS system. We screened 39 hormones from 88 plant hormone metabolites and constructed a partial regulatory network of auxin, jasmonic acid and cytokinin. GO analysis and enrichment of KEGG pathways in different metabolites showed that the 'plant hormone signal transduction' pathway was the most common. Our study showed that extreme low temperature increased the most levels of auxin, cytokinin and salicylic acid, and decreased levels of jasmonic acid and abscisic acid, and that levels of auxin, jasmonic acid and cytokinin in Dn1 were higher than those in J22. These changes in hormone levels were associated with changes in gene expression in synthesis, catabolism, transport and signal transduction pathways. These results differ from the previous hormone regulation mechanisms, which were mostly obtained at 4 °C. Our results provide a basis for further understanding the molecular mechanisms by which plant endogenous hormones regulate plant freezing stress tolerance.

Using feed-forward perceptron Artificial Neural Network (ANN) model to determine the rolling force, power and slip of the tandem cold rolling.

In this paper, an Artificial Neural Network (ANN) is used to investigate the influence of rolling parameters such as thickness reduction, inter-strand tension, rolling speed and friction on the rolling force, rolling power, and slip of tandem cold rolling. For this reason, the rolling power was derived for 195 various experiments through a series of observation tests. The network is trained and tested using real data collected from a practical tandem rolling line. The best topology of the ANN is determined by Broyden-Fletcher-Goldfarb-Shanno (BFGS) training algorithm and error, and nine neurons in the hidden layer had the best performance. The average of the training, testing, and validating correlation coefficients data sets are mentioned 0.947, 0.924, and 0.943, respectively. The obtained results show MSE value 4.2 × 10-4 for predicting slip. In addition, the effect of friction and angular velocity condition on the cold rolling critical slip phenomena are investigated. The results show that ANNs can accurately predict the cold rolling parameters considered in this study.

A Deep-Learning Error Detection System in Radiation Therapy.

Delivering radiation therapy based on erroneous or corrupted treatment plan data has previously and unfortunately resulted in severe, sometimes grave patient harm. Aiming to prevent such harm and improve safety in radiation therapy treatment, this work introduces a novel, yet intuitive algorithm for strategically structuring the complex and unstructured data typical of modern treatment plans so their treatment sites may automatically be verified with deep-learning architectures. The proposed algorithm utilizes geometric and dose plan parameters to represent each plan's data as a heat map to feed a deep-learning classifier that will predict the plan's treatment site. Once it is returned by the classifier, a plan's predicted site can be compared to its documented intended site, and a warning raised should the two differ. Using real head-neck, breast, and prostate treatment plan data retrieved at two hospitals in the United States, the algorithm is evaluated by observing the accuracy of convolutional neural networks (ConvNets) in correctly classifying the structured heat map data. Many well-known ConvNet architectures are tested, and ResNet-18 performs the best with a testing accuracy of 97.8% and 0.979 F-1 score. Clearly, the heat maps generated by the proposed algorithm, despite using only a few of the many available plan parameters, retain enough information for correct treatment site classification. The simple construction and ease of interpretation make the heat maps an attractive choice for classification and error detection.

[Neurocognitive impairment and characteristics of neurocognitive performance among people with HIV on antiretroviral treatment].

Objective: Using two measuring tools to examine the prevalence and correlates of neurocognitive impairment (NCI) as well as characteristics of neurocognitive performance among people with HIV (PWH) on antiretroviral treatment (ART). Methods: A total of 2 250 treated PWH from the Comparative HIV and Aging Research in Taizhou (CHART) were recruited in Taizhou, Zhejiang province. The Chinese version of the Mini-mental State Examination (MMSE) and the International HIV Dementia Scale (IHDS) were used to evaluate their neurocognitive performance. Cluster analysis was conducted on the seven cognitive domains in the scale. Results: Among 2 250 treated PWH, 48.0% (1 080/2 250) were aged 45 to 89, 79.2% (1 782/2 250) were male, and 37.8% (852/2 250) had primary school education or below. The prevalence of neurocognitive impairment judged by MMSE and IHDS among HIV-infected people was 14.3% (321/2 250) and 31.8% (716/2 250), respectively. Aged 60 to 89 (aOR=2.63, 95%CI:1.52-4.56), depressive symptoms (aOR=5.58, 95%CI:4.20-7.40) and treatment with EFV (aOR=2.86, 95%CI:1.89-4.34) were main risk factors of NCI diagnosed by MMSE. Male (aOR=0.71, 95%CI:0.51-1.00), overweight (aOR=0.63, 95%CI:0.44-0.89), and high education level (aOR=0.11, 95%CI:0.05-0.25) were protective factors of NCI diagnosed by MMSE. Aged 60 to 89 (aOR=3.10, 95%CI:2.09-4.59), depressive symptoms (aOR=1.78, 95%CI:1.44-2.20) and treatment with EFV (aOR=1.79, 95%CI:1.41-2.29) were risk factors of NCI diagnosed by IHDS. Male (aOR=0.75, 95%CI:0.58-0.97), underweight (aOR=0.67, 95%CI:0.47-0.96), baseline CD4+ T lymphocyte (CD4) counts ≥350 cells/µl (aOR=0.69, 95%CI:0.53-0.91) and high education level (aOR=0.23, 95%CI:0.14-0.39) were protective factors of NCI diagnosed by IHDS. The neurocognitive performance of HIV-infected people can be divided into four main types. Among four types, age, gender, education level, alcohol drinking, depressive symptoms, waist-to-hip ratio, hypertension, diabetes, baseline CD4 counts and treatment with EFV were different statistically (all P<0.05). Conclusions: There are four main types of neurocognitive performance in treated PWH. The prevalence of NCI is high among this population, underscoring the need for tailored prevention and intervention.
