Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

This paper reported a type 1 diabetes patient who had severe diabetic nephropathy, retinopathy, hypertension, and hypothyroidism before pregnancy. The patient's blood glucose control was poor before pregnancy, and the complications were not properly treated. This was an unintended pregnancy, with a pre-pregnancy glycated hemoglobin A1c of 7.8% and early pregnancy urine protein of 3.81-4.53 g/24 h. Considering the patient's poor blood glucose control before pregnancy and the lack of proper treatment for multiple complications including nephropathy, a multidisciplinary consultation at an external hospital recommended termination of the pregnancy. However, the patient was determined to continue the pregnancy and was referred to Peking University First Hospital. Through strict blood glucose control, monitoring and evaluation of complications, and comprehensive management, the patient's blood glucose and blood pressure were well controlled during pregnancy. Regular monitoring of urine protein, renal function, and ocular fundus was conducted. At 31 weeks and 4 days of gestation, the patient's 24-hour urine protein significantly increased. After promoting fetal lung maturity, a cesarean section was performed at 34 weeks and 1 day of gestation, resulting in a successful delivery with good maternal and neonatal outcomes. At the 42-day postpartum follow-up, the patient's blood glucose and blood pressure were stable, urine protein returned to pre-pregnancy levels, and the infant was in good general condition.

Objectives:To systematically evaluate the clinicopathological features and diagnosis and treatment characteristics of cervical metastasis in ovarian cancer patients in order to reduce misdiagnosis and missed diagnosis.Methods:Studies on cervical metastasis of ovarian cancer were searched in PubMed, Web of Science, CNKI, SinoMed, Wanfang, and VIP databases, and the search period was from the establishment of the database to September 30, 2024. After literature screening and data extraction by two researchers, descriptive analysis was used to systematically evaluate the included studies.Results:A total of 21 studies were included, including 87 patients, of which 11 were case reports and 10 were retrospective series of case studies. Qualitative analysis showed that the most common clinical manifestations were abnormal vaginal bleeding and drainage (61.4%, 27/44). The most common pathological type was high-grade serous carcinoma (71.4%, 40/56). 97.0% (33/34) of the patients had International Federation of Gynecology and Obstetrics (FIGO) stage Ⅲ to Ⅳ. In 30.6%(19/62) of patients, the diagnosis of ovarian primary and cervical metastases was not synchronized. Among them, 17.7%(11/62) of the primary lesions were diagnosed 6(range from 1 to 26)months earlier than the metastases. 12.9%(8/62) of the primary lesions were diagnosed 1(range from 1 to 6)months later. The median overall survival was 5 months (range 1/10 to 120 months).Conclusions:Cervical metastasis of ovarian cancer is rare, its clinical manifestations can be similar to primary cervical cancer, the differential diagnosis is difficult, the overall prognosis is poor, timely and accurate diagnosis, reasonable planning and treatment of cervical metastasis of ovarian cancer are very important for the prognosis of patients.

Objective:To systematically review and evaluate prediction models for aspiration risk in enteral nutrition patients, providing a reference for the development and application of future models.Methods:Literature related to prediction models for aspiration risk in enteral nutrition patients was searched in China National Knowledge Infrastructure, Wanfang Data, China Biology Medicine disc, Web of Science, Cochrane Library, Embase, and PubMed, with the search period covering from the inception of the databases to August 30, 2024. Two researchers independently conducted literature screening and data extraction, and the PROBAST tool was used to assess the risk of bias and applicability of the included studies.Results:A total of 18 studies were included, involving 24 prediction models, with sample sizes ranging from 103 to 512 and an event rate of 9.46% to 49.87%. The top six predictive variables reported most frequently were baseline age, history of aspiration, length of nasogastric tube insertion, nutritional risk, impaired consciousness, and Acute Physiology and Chronic Health Evaluation-Ⅱscore. The area under the receiver operating characteristic curve of the models ranged from 0.756 to 0.992. Twelve studies reported model calibration, six studies conducted internal validation only, one study conducted external validation only, and four studies performed both internal and external validation. The overall applicability of the 18 studies was good, but the risk of bias was high, mainly due to improper handling of continuous variables and missing data.Conclusions:The aspiration risk prediction models developed in various studies for enteral nutrition patients show good applicability but carry a high risk of bias. Future efforts should focus on further optimizing the model construction process, internal and external validation, and result analysis to provide more reliable and scientific tools for clinical aspiration risk assessment.

Objective:To explore the clinical value of autologous umbilical cord whole blood(UCB) priming of the cardiopulmonary bypass(CPB) circuit in neonatal cardiac surgery for congenital heart disease(CHD).Methods:This prospective non-randomized controlled trial included neonates undergoing CHD surgery at Guangdong Provincial People’s Hospital from August 2024 to January 2025. The experimental group used autologous UCB for CPB circuit priming, while the control group used adult allogeneic blood(AAB) priming when UCB was unavailable. Preoperative characteristics, intraoperative CPB and aortic cross-clamping(ACC) times, postoperative ICU stay duration, mechanical ventilation time, and hospitalization length were compared.Results:There were no significant differences in preoperative baseline characteristics between the two groups( P>0.05). At the end of surgery, red blood cell count(RBC), hemoglobin level(Hb), and creatine kinase(CK) showed no significant differences between the groups( P> 0.05). Additionally, perioperative left ventricular ejection fraction(LVEF) demonstrated no statistically significant variations( P>0.05). At surgery completion, the UCB group exhibited lower hematocrit(HCT) and higher blood lactic acid(Lac) levels but these differences resolved by 6 hours postoperatively( P>0.05). The UCB group had higher maximum vasoactive-inotropic scores(VISmax) within 48 hours and longer ICU stays, though total hospitalization and mechanical ventilation durations showed no significant differences( P>0.05). Conclusion:Autologous UCB priming reduces AAB requirements and has minimal impact on postoperative cardiac and pulmonary function recovery, or homeostasis., which is safe and feasible. This study provides evidence supporting the clinical application of UCB priming in CPB circuits.

OBJECTIVE To study the levels of serum chitinase-like protein-40(YKL-40),protease-activated recep-tor 1(PAR1)messenger ribonucleic acid(mRNA)and programmed cell death molecule 5(PDCD5)in patients with influenza A virus infection-related pneumonia,and to investigate their relationship with prognosis.METHODS A total of 951 patients with simple influenza A virus infection diagnosed and treated in Linfen People's Hospital from Jan.2022 to Jan.2024 were selected as the influenza A group,166 patients with influenza A virus infection-related pneumonia were selected as the influenza A pneumonia group,963 healthy people who underwent physical examination in the hospital during the same period were selected as the healthy group,and the levels of serum YKL-40,PAR1 mRNA and PDCD5 were compared among the three groups.According to the prognosis of pa-tients with influenza A virus infection-related pneumonia,the patients in the influenza A pneumonia group were di-vided into a good prognosis group(139 cases)and a poor prognosis group(27 cases),the levels of serum YKL-40,PAR1 mRNA and PDCD5 were compared between the two groups,and the predictive value of the combina-tion of the three on the prognosis of patients with influenza A virus infection-related pneumonia was analyzed.RESULTS The levels of serum YKL-40,PAR1 mRNA and PDCD5 in the influenza A pneumonia group were(39.41±7.85)ng/ml,(11.31±3.52)and(3.04±0.89)μg/L,respectively,which were higher than those in the influenza A group[(28.19±5.88)ng/ml,(5.87±1.29),(1.96±0.55)μg/L]and the healthy group,and those in the influenza A group was higher than in the healthy group(P＜0.05).The levels of serum YKL-40,PAR1 mRNA and PDCD5 in the poor prognosis group were(45.73±9.63)ng/ml,(13.20±4.11)μg/L and(3.96±1.32)μg/L,respectively,which were higher than those in the good prognosis group(P＜0.05).The ar-ea under the curve(AUC)of serum YKL-40,PAR1 mRNA,and PDCD5 combined to predict the prognosis of pa-tients with influenza A virus infection-associated pneumonia was 0.840,which was higher than that of the three tests alone(P＜0.05).CONCLUSION The occurrence of influenza A virus infection and its related pneumonia cause elevated levels of serum YKL-40,PAR1 mRNA and PDCD5,and the combination of the three can effective-ly improve the prognostic value of patients with influenza A virus infection-related pneumonia.
