A palladium-catalyzed cascade reaction of α,β-unsaturated N -tosylhydrazones with iodoarene derivatives containing a nucleophilic group has been developed, which provides facile access to 2 H -chromenes and 2 H -quinolines, respectively. Additionally, the double Pd-carbene migratory insertion/nucleophilic substitution processes for the synthesis of a ternary heterocyclic skeleton were possible in the developed catalytic system.

Osteoarthritis (OA) is the most common type of arthritis characterized by progressive cartilage degradation, with its pathogenesis closely related to chondrocyte autophagy. Chondrocytes are the only cells in articular cartilage, and the function of chondrocytes plays a vital role in maintaining articular cartilage homeostasis. Autophagy, an intracellular degradation system that regulates energy metabolism in cells, plays an incredibly important role in OA. During the early stages of OA, autophagy is enhanced in chondrocytes, acting as an adaptive mechanism to protect them from various environmental changes. However, with the progress of OA, chondrocyte autophagy gradually decreases, leading to the accumulation of damaged organelles and macromolecules within the cell, prompting chondrocyte apoptosis. Numerous studies have shown that cartilage degradation is influenced by the senescence and apoptosis of chondrocytes, which are associated with reduced autophagy. The relationship between autophagy, senescence, and apoptosis is complex. While autophagy is generally believed to inhibit cellular senescence and apoptosis to promote cell survival, recent studies have shown that some proteins are degraded by selective autophagy, leading to the secretion of the senescence-associated secretory phenotype (SASP) or increased SA-β-Gal activity in senescent cells within the damaged region of human OA cartilage. Autophagy activation may lead to different outcomes depending on the timing, duration, or type of its activation. Thus, our study explored the complex relationship between chondrocyte autophagy and OA, as well as the related regulatory molecules and signaling pathways, providing new insights for the future development of safe and effective drugs targeting chondrocyte autophagy to improve OA., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Li, Li, Li, Zhou, Zhu, Zhang, Huang, Zhao, Zhao and Chen.)

Background: The working environment of submarine crews is also very special. They are in a closed, high-temperature, high-noise, high-vibration and narrow working and living space for a long time, and they suffer from physical discomfort caused by seasickness, which will affect the mental health of officers and soldiers. American psychologists have achieved positive results in psychological resilience training for officers and soldiers from the perspective of positive psychology. At present, there are few reports on the correlation between psychological resilience in the field of domestic research on submarine crew psychology, and it is necessary to conduct further research., Aim: To explore the impact of active psychological regulation intervention on officers and soldiers operating in confined spaces at sea., Methods: A total of 121 soldiers working in a confined space of a large ship were randomly divided into an experimental group and a control group. The 50 soldiers in the experimental group were given a training course intervention, while the 71 soldiers in the control group did not receive any intervention measures. The Pittsburgh Sleep Quality Index, Psychological Resilience Scale, military Psychological Stress Self-Assessment Questionnaire, and General Self-Efficacy Scale scores were compared before and 6 months after the intervention., Results: Under the positive psychological control intervention, except for sleep efficiency ( P = 0.05), the difference between the remaining dimensions of the Pittsburgh Sleep Quality Index scores and the total scores of the experimental group compared with the control group was statistically significant ( P < 0.05); the assessment of the psychological condition showed that, in addition to the Psychological Stress Self-assessment Questionnaire for Military Personnel scores ( P = 0.05), the scores of the Mental Toughness Scale (Dispositional Resilience Scale Resilience II) in the experimental group, General Self-Efficacy Scale scores were statistically significant ( P < 0.05) compared to pre-intervention., Conclusion: Positive psychological intervention and control can improve the sleep state and psychological state of officers and soldiers working in confined space at sea., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2024.

Background: Tinnitus affects 10%-30% of the population. Recent evidence suggests that tinnitus is associated with spleen deficiency. However, compared with kidney deficiency-related tinnitus, less research has been conducted on the impact of spleen deficiency-related tinnitus., Aim: To investigate the clinical efficacy of using Guipi Wan and dietary and lifestyle modification based on traditional Chinese medicine for treatment of patients with spleen and stomach deficiency-related tinnitus., Methods: We enrolled 110 patients with spleen and stomach deficiency-related tinnitus who were distributed into treatment (58 cases) and control (52 cases) groups. Tinnitus severity, sleep quality and emotional state were assessed by questionnaires [Tinnitus Evaluation Questionnaire (TEQ); Pittsburgh Sleep Quality Index (PSQI); Depression-Anxiety-Stress Scale-21 (DASS-21)] that were used for analysis in the two groups during the initial and intervention and after. In the treatment group, patients were treated with oral administration of Guipi Wan and consulted for healthy dietary and lifestyle modification. In the control group, patients were only assessed and not treated., Results: At the end of the 6-months, TEQ scores decreased significantly in the treatment group ( P = 0.021) but not in the Control group. Significant effects in the treatment group were noted for PSQI total score ( P = 0.043) and several PSQI component scores in the treatment group ( P < 0.05). After treatment, the DASS-21 scores were significantly reduced in the treatment group ( P < 0.05)., Conclusion: Guipi Wan combined with dietary and lifestyle modification based on regulating the spleen and stomach can be considered core to the treatment of tinnitus related to spleen and stomach deficiency., Competing Interests: Conflict-of-interest statement: The authors have no conflicts of interest to declare., (©The Author(s) 2024.

In this study, we applied thermal dissipation probe technology to examine sap flow in various directions (east, south, west, and north) and at different depths (0-2, 2-4, 4-6 cm) within the stem of natural Picea mongolica trees in the eastern of Otindag Sandy Land to provide a scientific basis for accurately quantifying water consumption of P. mongolica forests through transpiration and to enhance the understanding of water relations. The results showed that the diurnal variation of sap flow in different directions displayed a unimodal curve, with the sap flow sequence being south>east>west>north. The sap flow at different sapwood depths exhibited an obvious unimodal curve, with a significant decrease as sapwood depth increased. Compared with that calculated from the mean sap flux density in four directions (23.57 kg·d -1 ), water consumption calculated using the mean value in south-east, east-west, south-west, north-east, north-south, and north-west was overestimated by 10.2%, 5.5%, 14.5%, and underestimated by 12.3%, 8.2%, 9.8%, respectively. The water consumption calculated using the values from the east, south, and west was overestimated by 6.1%, 14.4%, and 15.4%, respectively, and underestimated by 30.7% in the north. In addition, compared with the water consumption calculated from the mean value in three sapwood depths (48.51 kg·d -1 ), that calculated using sap flux density at sapwood depths of 0-2, 2-4, and 4-6 cm were overestimated by 18.8%, underestimated by 1.7%, and underestimated by 62.9%, respectively. These results indicated that sap flow of P. mongolica had significant azimuthal and radial variations, which considerably influence the estimation of tree water consumption. Installing probes at 0-2 cm simultaneously in both the north and east of the trunk could effectively reduce the estimation error of whole-tree water consumption by 4.2%. This approach enabled the accurate quantification of water consumption of individual P. mongolica trees in sandy areas, thereby improving the precision of transpiration water consumption estimates scaling up from individual level to stand level.

Objective: To evaluate the surgical outcomes of a modified technique for treating congenital cilial entropion in children, which involves reducing tension step by step in the epicanthus and lower eyelid incision., Methods: The observational group consisted of 153 pediatric patients (81 males and 72 females) who were treated using the modified technique, whereas the control group included 124 patients (68 males and 56 females) who were treated using the rotating suture surgery. All the participants were bilateral. Surgical outcomes were classified as good, fair, or poor, and the recurrence rate, scar condition, inferior eyelid position, and patient satisfaction were also assessed., Results: The mean follow-up period was 9.13 ± 3.50 months (range: 3-14 months) for the observational group and 6.93 ± 4.51 months (range: 3-14 months) for the control group. In the observational group, surgical success with "good" outcomes was achieved in 300 eyes (98.04%), compared to 224 eyes (90.32%) in the control group. No recurrence occurred in the observational group, whereas the recurrence rate in the control group was 4.43%. Postoperative scar formation was mild in the observational group. The average scar score was 1.27 ± 0.96 in the observational group and 2.70 ± 0.99 in the control group, with a statistically significant difference (P < 0.001). Neither overcorrection nor postoperative ectropion was observed in both groups., Conclusion: The modified technique effectively corrected medial entropion and trichiasis in the lower eyelid, resulting in stable postoperative outcomes, mild scar formation, quick recovery, flexible eyelid motility, and stable ocular surface. Therefore, it can be widely applied to children with congenital entropion and trichiasis., (Copyright © 2024. Published by Elsevier Ltd.)

Background: Surgical care of the hand plays a crucial role in the medical field, as problems with the hand can profoundly affect a patient's quality of life and function. In order to meet the needs of patients, improve patient satisfaction and improve treatment outcomes, high-quality service models have been introduced in the field of nursing., Aim: To explore the effect analysis of applying high-quality service model to surgical nursing., Methods: We conducted a retrospective study of patients who underwent hand surgery at our hospital between 2019 and 2022, using a quality service model that included improved patient education, pain management, care team collaboration, and effective communication. Another group of patients received traditional care as a control group. We compared postoperative recovery, satisfaction, complication rate, and length of hospital stay between the two groups. Inferential statistics were used to compare the difference between the two groups by independent sample t test, Chi-square test and other methods to evaluate the effect of intervention measures., Results: Postoperative recovery time decreased from 17.8 ± 2.3 d to 14.5 ± 2.1 d, pain score decreased from 4.7 ± 1.9 to 3.2 ± 1.4, and hand function score increased from 78.4 ± 7.1 to 88.5 ± 6.2. In terms of patient satisfaction, the quality service model group scored 87.3 ± 5.6 points, which was significantly higher than that of the traditional care group (74.6 ± 6.3 points). At the same time, patients' understanding of medical information also improved from 6.9 ± 1.4 to 8.6 ± 1.2. In terms of postoperative complications, the application of the quality service model reduced the incidence of postoperative complications from 26% to 10%, the incidence of infection from 12% to 5%, and the incidence of bleeding from 10% to 3%. The reduction in these data indicates that the quality service model plays a positive role in reducing the risk of complications. In addition, the average hospital stay of patients in the quality service model group was shortened from 6.8 ± 1.5 d to 5.2 ± 1.3 d, and the hospitalization cost was also reduced from 2800 ± 600 yuan to 2500 ± 500 yuan., Conclusion: Applying a quality service model to hand surgery care can significantly improve patient clinical outcomes, including faster recovery, less pain, greater satisfaction, and reduced complication rates., Competing Interests: Conflict-of-interest statement: The authors declare no conflicts of interest for this article., (©The Author(s) 2024.

Post-synthetic modification plays a crucial role in precisely adjusting the structure and functions of advanced materials. Herein, we report the self-assembly of a tubular heterometallic Pd 3 Cu 6 L1 6 capsule that incorporates Pd(II) and CuL1 metalloligands. This capsule undergoes further modification with two tridentate anionic ligands (L2) to afford a bicapped Pd 3 Cu 6 L1 6 L2 2 capsule with an Edshammer polyhedral structure. By employing transition metal ions, acid, and oxidation agents, the bicapped capsule can be converted into an uncapped one. This uncapped form can then revert back to the bicapped structure on the addition of Br - ions and a base. Interestingly, introducing Ag + ions leads to the removal of one L2 ligand from the bicapped capsule, yielding a mono-capped Pd 3 Cu 6 L1 6 L2 structure. Furthermore, the size of the anions critically influences the precise control over the post-synthetic modifications of the capsules. It was demonstrated that these capsules selectively encapsulate tetrahedral anions, offering a novel approach for the design of intelligent molecular delivery systems., (© 2024 Wiley-VCH GmbH.)

Purpose: To date, our understanding of IgA nephropathy (IgAN) pathophysiology has remained incomplete; therefore, treatment remains largely empiric, and the efficacy and safety of immunosuppressants remain controversial. We aimed to assess the efficacy and safety of hydroxychloroquine and leflunomide therapy in a retrospective cohort of patients with IgAN., Methods: We screened the IgAN registration database in our department, and a total of 159 kidney patients with biopsy-confirmed IgAN were enrolled, with 57 patients receiving hydroxychloroquine plus a renin-angiotensin system inhibitor (hydroxychloroquine group), 52 patients receiving leflunomide plus a renin-angiotensin system inhibitor (leflunomide group), and 50 patients receiving only a renin-angiotensin system inhibitor (renin-angiotensin system inhibitor-only group). Changes in proteinuria, hematuria, and the estimated glomerular filtration rate (eGFR), as well as adverse events, were analyzed during the follow-up period., Results: At the end of 6-month follow-up, proteinuria significantly decreased by 70.36 (57.54, 79.33)%, 57.29 (46.79, 67.29)% and 41.20 (25.76, 48.94)% in the hydroxychloroquine, leflunomide and renin-angiotensin system inhibitor-only groups, respectively, compared to baseline (all P values < 0.001). Hematuria significantly decreased by 71.07 (56.48, 82.47)% in the leflunomide group (P < 0.001). The eGFR improved by 3.72 ± 2.97%, 3.16 ± 2.00% and 1.91 ± 2.41%, respectively, in the hydroxychloroquine, leflunomide and renin-angiotensin system inhibitor-only groups, but without statistical significance. No serious adverse events occurred during the follow-up period., Conclusion: Both hydroxychloroquine combined with a renin-angiotensin system inhibitor and leflunomide combined with a renin-angiotensin system inhibitor were more effective than a renin-angiotensin system inhibitor alone in improving proteinuria in IgAN patients. Hydroxychloroquine was more effective in reducing proteinuria, and leflunomide showed superiority in reducing hematuria. Our results need to be verified in large-scale randomized controlled trials., (© 2024. The Author(s).)

Laryngopharyngeal reflux disease (LPRD) is an inflammatory condition in the laryngopharynx and upper aerodigestive tract mucosa caused by reflux of stomach contents beyond the esophagus. LPRD commonly presents with sym-ptoms such as hoarseness, cough, sore throat, a feeling of throat obstruction, excessive throat mucus. This complex condition is thought to involve both reflux and reflex mechanisms, but a clear understanding of its molecular mechanisms is still lacking. Currently, there is no standardized diagnosis or treatment protocol. Therapeutic strategies for LPRD mainly include lifestyle modifications, proton pump inhibitors and endoscopic surgery. This paper seeks to provide a comprehensive overview of the existing literature regarding the mechanisms, patho-physiology and treatment of LPRD. We also provide an in-depth exploration of the association between LPRD and gastroesophageal reflux disease., Competing Interests: Conflict-of-interest statement: The authors have no conflicts of interest to declare., (©The Author(s) 2024.

Metal-organic cages (MOCs) are supramolecular coordination complexes that have internal cavities for hosting guest molecules and exhibiting various properties. However, the functions of MOCs are limited by the choice of the building blocks. Post-synthetic modification (PSM) is a technique that can introduce new functional groups and replace existing ones on the MOCs without changing their geometry. Among many PSM methods, covalent PSM is a promising approach to modify MOCs with tailored structures and functions. Covalent PSM can be applied to either the internal cavity or the external surface of the MOCs, depending on the functionality expected to be customized. However, there are still some challenges and limitations in the field of covalent PSM of MOCs, such as the balance between the stability of MOCs and the harshness of organic reactions involved in covalent PSMs. This concept article introduces the organic reaction types involved in covalent PSM of MOCs, their new applications after modification, and summarizes and provides an outlook of this research field., (© 2024 Wiley-VCH GmbH.)

Background: Portal vein thrombosis (PVT), a complication of liver cirrhosis, is a major public health concern. PVT prediction is the most effective method for PVT diagnosis and treatment., Aim: To develop and validate a nomogram and network calculator based on clinical indicators to predict PVT in patients with cirrhosis., Methods: Patients with cirrhosis hospitalized between January 2016 and December 2021 at the First Hospital of Lanzhou University were screened and 643 patients with cirrhosis who met the eligibility criteria were retrieved. Following a 1:1 propensity score matching 572 patients with cirrhosis were screened, and relevant clinical data were collected. PVT risk factors were identified using the least absolute shrinkage and selection operator (LASSO) and multivariate logistic regression analysis. Variance inflation factors and correlation matrix plots were used to analyze multicollinearity among the variables. A nomogram was constructed to predict the probability of PVT based on independent risk factors for PVT, and its predictive performance was verified using a receiver operating characteristic curve (ROC), calibration curves, and decision curve analysis (DCA). Finally, a network calculator was constructed based on the nomograms., Results: This study enrolled 286 cirrhosis patients with PVT and 286 without PVT. LASSO analysis revealed 13 variables as strongly associated with PVT occurrence. Multivariate logistic regression analysis revealed nine indicators as independent PVT risk factors, including etiology, ascites, gastroesophageal varices, platelet count, D-dimer, portal vein diameter, portal vein velocity, aspartate transaminase to neutrophil ratio index, and platelet-to-lymphocyte ratio. LASSO and correlation matrix plot results revealed no significant multicollinearity or correlation among the variables. A nomogram was constructed based on the screened independent risk factors. The nomogram had excellent predictive performance, with an area under the ROC curve of 0.821 and 0.829 in the training and testing groups, respectively. Calibration curves and DCA revealed its good clinical performance. Finally, the optimal cutoff value for the total nomogram score was 0.513. The sensitivity and specificity of the optimal cutoff values were 0.822 and 0.706, respectively., Conclusion: A nomogram for predicting PVT occurrence was successfully developed and validated, and a network calculator was constructed. This can enable clinicians to rapidly and easily identify high PVT risk groups., Competing Interests: Conflict-of-interest statement: The authors reported no financial interests or potential conflicts of interest., (©The Author(s) 2024.

Hollow nanoporous carbon architectures (HNCs) present significant utilitarian value for a wide variety of applications. Facile and efficient preparation of HNCs has long been pursued but still remains challenging. Herein, we for the first time demonstrate that single-component metal-organic frameworks (MOFs) crystals, rather than the widely reported hybrid ones which necessitate tedious operations for preparation, could enable the facile and versatile syntheses of functional HNCs. By controlling the growth kinetics, the MOFs crystals (STU-1) are readily engineered into different shapes with designated styles of crystalline inhomogeneity. A subsequent one-step pyrolysis of these MOFs with intraparticle difference can induce a simultaneous self-hollowing and carbonization process, thereby producing various functional HNCs including yolk-shell polyhedrons, hollow microspheres, mesoporous architectures, and superstructures. Superior to the existing methods, this synthetic strategy relies only on the complex nature of single-component MOFs crystals without involving tedious operations like coating, etching, or ligand exchange, making it convenient, efficient, and easy to scale up. An ultra-stable Na-ion battery anode is demonstrated by the HNCs with extraordinary cyclability (93 % capacity retention over 8000 cycles), highlighting a high level of functionality of the HNCs., (© 2024 Wiley‐VCH GmbH.)

To examine whether circulating interleukin-6 (IL-6) levels (CirIL6) have a causal effect on blood pressure using Mendelian randomization (MR) methods. We used data from genome-wide association studies (GWAS) of European ancestry to obtain genetic instruments for circulating IL-6 levels and blood pressure measurements. We applied several robust MR methods to estimate the causal effects and to test for heterogeneity and pleiotropy. We found that circulating IL-6 had a significant positive causal effect on systolic blood pressure (SBP) and pulmonary arterial hypertension (PAH), but not on diastolic blood pressure (DBP) or hypertension. We found that as CirIL6 genetically increased, SBP increased using Inverse Variance Weighted (IVW) method (for ukb-b-20175, β = 0.082 with SE = 0.032, P = 0.011; for ukb-a-360, β = 0.075 with SE = 0.031, P = 0.014) and weighted median (WM) method (for ukb-b-20175, β = 0.061 with SE = 0.022, P = 0.006; for ukb-a-360, β = 0.065 with SE = 0.027, P = 0.014). Moreover, CirIL6 may be associated with an increased risk of PAH using WM method (odds ratio (OR) = 15.503, 95% CI, 1.025-234.525, P = 0.048), but not with IVW method. Our study provides novel evidence that circulating IL-6 has a causal role in the development of SBP and PAH, but not DBP or hypertension. These findings suggest that IL-6 may be a potential therapeutic target for preventing or treating cardiovascular diseases and metabolic disorders. However, more studies are needed to confirm the causal effects of IL-6 on blood pressure and to elucidate the underlying mechanisms and pathways., (© 2024.

A Pd-catalyzed thiocarbonylative cyclization of N-( o -iodoaryl)acrylamides with easily accessible thioformates has been developed. The reaction has a wide substrate scope with good yields and represents a powerful route to the synthesis of thioester-functionalized oxindoles. Both S -aryl and alkyl thioformates as the thioester sources were well tolerated. The active Pd-CO intermediate may play an important role in the transformation process.

Objective: To explore the effect of accurately localized mini anterolateral thigh perforator flap in repairing medium-sized skin and soft tissue defects in fingers. Methods: The study was a retrospective observational study. From December 2019 to September 2022, 15 patients with medium-sized skin and soft tissue defects who met the inclusion criteria in fingers were admitted to the Second Affiliated Hospital of Wenzhou Medical University, including 12 males and 3 females, aged 23 to 62 years. After debridement, the wounds were all accompanied by exposed tendons, bones, vessels and nerves, with an area from 4.0 cm×3.0 cm to 8.0 cm×3.5 cm. Computed tomography angiography and color Doppler ultrasonography examinations were performed on both lower limbs of the patient before surgery to accurately locate the anterolateral thigh perforators. When the flap with area from 6.0 cm×3.0 cm to 11.0 cm×4.0 cm was harvested, the flap was thinned. The artery and vein perforators of the flap were anastomosed respectively with the digital artery and dorsal metacarpal vein. If there was avulsion injury, infection, or burn in the recipient area, the main arterial and veinous vessels carried by the skin flap was anastomosed with the radial artery and accompanying vein. The lateral thigh cutaneous nerve carried by the flap was anastomosed with the stump of the digital nerve. The types of perforators of the lateral thigh artery were observed during operation and compared with the location of the vessels before operation. After operation, the survival and adverse complication of the flap were closely observed. During follow-up, the skin flap color, texture, and shape were observed; the wound healing in donor area was observed. At the last follow-up, the two-point discriminative distance of the affected finger pulp was measured, and the function of the affected finger was evaluated using the trial standard for the evaluation of functions of upper limbs of Hand Surgery Society of Chinese Medical Association, and the interphalangeal joint movement of the affected finger was observed; the patients' complaints about the adverse effects of flap resection on lower limbs were recorded. Results: During the operation, it was observed that the perforators of the flaps in 11 patients were the descending branch of the lateral circumflex thigh artery, in two patients, the perforators of skin flaps were the oblique branch of the lateral thigh artery, and the perforators in another two patients were the transverse branch of the lateral circumflex thigh artery, which were consistent with the preoperative vascular localization. After operation, all flaps survived without vascular crisis and infection. The patients were followed up for 6-12 months, the flaps had excellent color, texture, and appearance; only linear scars remained on the donor wound. At the last follow-up, the two-point discrimination distance in the finger pulp was 7-11 mm; the affected finger function was rated as excellent in 6 cases, good in 6 cases, and fair in 3 cases; the flexion and extension function of the finger was not affected; two patients complained of numbness in the lateral thigh after excision of the skin flap, and the other 13 patients had no complain of adverse complaints. Conclusions: The perforating branch in lateral thigh region can be accurately located by computed tomography angiography and color Doppler ultrasonography, accurate positioning of perforators before operation can reduce the damage to the donor area during the incision of the flap, the appearance and function of the affected finger can be restored to the maximum extent by thinning the transplanted flap and rebuilding the finger sensation. Therefore, it is an effective and reliable way to repair the medium-sized skin and soft tissue defects of fingers with the mini thigh anterolateral perforator flap.

Background: Previous studies mainly focused on risk factors in patients with mild cognitive impairment (MCI) or dementia. The aim of the study was to provide basis for preventing MCI in cognitive normal populations., Methods: The data came from a longitudinal retrospective study involving individuals with brain magnetic resonance imaging scans, clinical visits, and cognitive assessment with interval of more than 3 years. Multiple machine-learning technologies, including random forest, support vector machine, logistic regression, eXtreme Gradient Boosting, and naïve Bayes, were used to establish a prediction model of a future risk of MCI through a combination of clinical and image variables., Results: Among these machine learning models; eXtreme Gradient Boosting (XGB) was the best classification model. The classification accuracy of clinical variables was 65.90%, of image variables was 79.54%, of a combination of clinical and image variables was 94.32%. The best result of the combination was an accuracy of 94.32%, a precision of 96.21%, and a recall of 93.08%. XGB with a combination of clinical and image variables had a potential prospect for the risk prediction of MCI. From clinical perspective, the degree of white matter hyperintensity (WMH), especially in the frontal lobe, and the control of systolic blood pressure (SBP) were the most important risk factor for the development of MCI., Conclusion: The best MCI classification results came from the XGB model with a combination of both clinical and imaging variables. The degree of WMH in the frontal lobe and SBP control were the most important variables in predicting MCI., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Zhu, Liu, Ji, Liu and Huang.)
