ABSTRACT

BACKGROUND: Total knee arthroplasty (TKA) can reduce severe joint pain and improve functional disability in hemophilia. However, the long-term outcomes have rarely been reported in China. Therefore, this study aimed to evaluate the long-term outcomes and complications of TKA in Chinese patients with hemophilic arthropathy.

METHODS: We retrospectively reviewed patients with hemophilia who underwent TKA between 2003 and 2020, with at least 10 years of follow-up. The clinical results, patellar scores, patients’ overall satisfaction ratings, and radiological findings were evaluated. Revision surgery for implants during the follow-up period was recorded.

RESULTS: Twenty-six patients with 36 TKAs were successfully followed up for an average of 12.4 years. Their Hospital for Special Surgery Knee Score improved from an average of 45.8 to 85.9. The average flexion contracture statistically significantly decreased from 18.1° to 4.2°. The range of motion (ROM) improved from 60.6° to 84.8°. All the patients accepted patelloplasty, and the patients’ patellar score improved from 7.8 preoperatively to 24.9 at the last follow-up. There was no statistically significant difference in clinical outcomes between the unilateral and bilateral procedures, except for a better ROM at follow-up in the unilateral group. Mild and enduring anterior knee pain was reported in seven knees (19%). The annual bleeding event was 2.7 times/year at the last follow-up. A total of 25 patients with 35 TKAs were satisfied with the procedure (97%). Revision surgery was performed in seven knees, with 10- and 15-year prosthesis survival rates of 85.8% and 75.7%, respectively.

CONCLUSIONS: TKA is an effective procedure for patients with end-stage hemophilic arthropathy, which relieves pain, improves knee functions, decreases flexion contracture, and provides a high rate of satisfaction after more than ten years of follow-up.

ABSTRACT

BACKGROUND: The association between Ebstein anomaly and myocardial fibrosis, particularly in the left ventricle, has been controversial. We aimed to assess the prevalence of replacement fibrosis with a focus on the left ventricle (LV) using cardiac magnetic resonance (CMR), make a histopathological association between LV fibrosis and CMR findings, and explore whether LV fibrosis is an independent risk factor for cardiovascular disease mortality using a derived risk score.

METHODS: We performed a 12-year (2009-2021) retrospective cohort of adult patients with Ebstein anomaly who underwent CMR. The CMR evaluation included a comprehensive assessment of myocardial fibrosis by late gadolinium enhancement (LGE). Four postmortem samples were obtained from our cohort and stained using Masson trichrome to characterize LV fibrosis. We used Cox-regression analysis to identify and derive a prediction score that associated LV fibrosis with cardiovascular disease mortality.

RESULTS: We included 57 adults with Ebstein anomaly (52% men; median age, 29.52 [interquartile range, 21.24-39.17] years), of whom 12 died during follow-up. LGE prevalence by CMR was observed in 52.6% in any chamber; LV-LGE in 29.8%. Histopathological findings revealed a mid-wall pattern with predominantly interstitial fibrosis and minimal replacement fibrosis. LV-LGE was associated with increased risk of cardiovascular disease mortality (hazard ratio, 6.02 [95% CI, 1.22-19.91]) attributable to lateral and mid-wall LV segment involvement. Our mortality score achieved an overall good prediction capacity (R², 0.435; C statistic, 0.93; D_xy, 0.86).

CONCLUSIONS: There is a high prevalence of LV fibrosis replacement in adults with Ebstein anomaly, characterized by specific CMR and histological patterns. Furthermore, LV-LGE fibrosis is an independent predictor of cardiovascular disease mortality, which could be integrated into risk assessment in clinical management.

ABSTRACT

BACKGROUND: COVID-19 (coronavirus disease 2019) is associated with heightened risks of venous and arterial thrombosis and hospitalization due to respiratory failure. To assess whether prophylactic anticoagulation can safely reduce the frequency of venous and arterial thrombosis, hospitalization, and death in nonhospitalized patients with symptomatic COVID-19 and at least one thrombosis risk factor, we conducted the PREVENT-HD double-blind, placebo-controlled randomized trial (A Study of Rivaroxaban to Reduce the Risk of Major Venous and Arterial Thrombotic Events, Hospitalization and Death in Medically Ill Outpatients With Acute, Symptomatic COVID-19] Infection).

METHODS: PREVENT-HD was conducted between August 2020 and April 2022 at 14 US integrated health care delivery networks. A virtual trial design used remote informed consent and clinical monitoring and facilitated data collection through electronic health record integration with a cloud-based research platform. Nonhospitalized patients with symptomatic COVID-19 and at least one thrombosis risk factor were enrolled and randomly assigned to either 10 mg of oral rivaroxaban or placebo daily for 35 days. The primary efficacy outcome was time to first occurrence of a composite of symptomatic venous thromboembolism, myocardial infarction, ischemic stroke, acute limb ischemia, non-central nervous system systemic arterial embolism, hospitalization, or death through day 35. The principal safety end point was International Society on Thrombosis and Hemostasis critical-site or fatal bleeding. The last study visit was on day 49.

RESULTS: The study was terminated prematurely because of enrollment challenges and a lower-than-expected blinded pooled event rate. A total of 1284 patients underwent randomization with complete accrual of primary events through May 2022. No patients were lost to follow-up. The primary efficacy outcome occurred in 22 of 641 in the rivaroxaban group and 19 of 643 in the placebo group (3.4% versus 3.0%; hazard ratio, 1.16 [95% CI, 0.63-2.15]; P=0.63). No patient in either group experienced critical-site or fatal bleeding. One patient receiving rivaroxaban had a major bleed.

CONCLUSIONS: The study was terminated prematurely after enrollment of 32% of planned accrual because of recruitment challenges and lower-than-expected event rate. Rivaroxaban prescribed for 35 days in nonhospitalized patients with symptomatic COVID-19 at risk for thrombosis did not appear to reduce a composite end point of venous and arterial thrombotic events, hospitalization, and death.

ABSTRACT

INTRODUCTION: social or school factors influence the acquisition and selection of foods to be consumed.

OBJECTIVE: identifying the socioeconomic or school level that has the greatest weight in the acquisition of food in Mexican households.

METHODS: cross-sectional, retrospective and comparative study based on the database of the 2018 National Household Expenditure-Income Survey of Mexico. We worked with the national total of 73,274 Mexican households. The variables considered were: expenditure module of food and beverages, school grade of the head of the family and socioeconomic status to which the household belongs. For the statistical analysis, the following tests were used: linear regression analysis, as well as variance analysis, Snedecor’s F test, post-hoc test and Schefé’s confirmatory test.

RESULTS: socioeconomic status has a greater weight (p < .001) for food acquisition. Sugary drinks were the most widely acquired in all social and school levels. The lowest social level is the one who acquires the most cereals, fats, sugars and legumes, while for high school levels animal foods and processed meats are the ones most frequently acquired.

CONCLUSION: the socioeconomic level has a great weight in the acquisition and variety of foods, although this does not mean that foods obtained are the healthiest. Therefore, public policies are urgently required in favor of nutritional education at all school levels, which promote the purchase of healthy foods and compete with commercial advertising strategies.

ABSTRACT

This study aimed to identify factors that affect the prognosis of children with pulmonary valve atresia and intact ventricular septum treated with transthoracic balloon dilation of the pulmonary valve. The study included 148 participants who were followed up for 5 years. Of these, 10 died, while 138 survived. Independent sample t-test and χ2 test were used to analyze clinical data of children in the death and survival groups. It was found that height, weight, body surface area, arterial oxygen saturation, degree of tricuspid regurgitation, pulmonary valve cross valve pressure difference, ICU length of stay, length of stay, reoperation intervention, and complications were statistically significant (P<0.05). ROC curve analysis of the measurement indicators with statistically significant differences showed that height, weight, body surface area, arterial oxygen saturation, ICU length of stay, and length of stay had AUCs ranging from 0.723 to 0.870. Logistic regression analysis revealed that the degree of tricuspid regurgitation, pulmonary valve cross valvular pressure difference, ICU length of stay, reoperation intervention, and complications were independent risk factors that affect the prognosis of patients with PA/IVS undergoing transthoracic balloon dilation of pulmonary valve. The study proposed a nomogram prediction model using R language software 4.0 “rms” package, which was validated using calibration curve and decision curve. The model had a C-index of 0.667 (95% CI: 0.643-0.786) and high degree of fit. This study provides clinicians with a prediction model to identify children with poor prognosis after treatment with transpulmonary valve balloon dilatation. .

ABSTRACT

PURPOSE: To integrate digital dynamic smile aesthetic simulation (DSAS) cognitive education in orthodontic practicum and evaluate the teaching effects.

METHODS: A total of 32 dental students during orthodontic practicum were randomly divided into two groups. One group received traditional teaching method to draft treatment plan, and another group was implemented with DSAS teaching method. Then two groups exchanged. Students were asked to grade both teaching methods and statistical analysis was performed on the scoring results with SPSS 24.0 software package.

RESULTS: The scores of the DSAS teaching method was much higher than traditional method, and the difference was statistically significant(P=0.012). Students considered that DSAS teaching method was more “novel and fascinating”, and also “convenient for comprehending of orthodontic treatment”. Students hoped to popularize the DSAS teaching method in future orthodontic practicum.

CONCLUSIONS: As a novel teaching method, DSAS is more intuitive and vivid to stimulate students’ interest in learning, and it is helpful to improve the effect of orthodontic practical teaching.

ABSTRACT

PURPOSE: To evaluate the long-term clinical efficacy of short implants and analyze the influencing factors of the survival rate.

METHODS: A total of 178 patients who received implant therapy in the Department of Stomatology, the Fourth Affiliated Hospital of Nanchang University from January 2010 to December 2014 were selected, including 334 short implants of Bicon (implant length ≤6 mm). The basic condition, restoration design, short implant survival rate and complications were observed and analyzed. SPSS 24.0 software package was used for data analysis.

RESULTS: The average follow-up time of short implants was 96±17 months. During the observation period, 20 implants failed, 1 implant had mechanical complications and 6 implants had biological complications. Based on the analysis of implants and patients, the long-term cumulative survival rate of short implants was 94.0%(over 5 years survival rate was 96.4%) and 90.4% respectively. There was no significant difference between the survival rate of short implants and the patient’s gender, age, whether to use special operation and the type of jaw teeth(P＜0.05). Smoking and periodontitis were risk factors for failure of short implants(P＜0.05).The difference of short implant survival rate between short implants restoration with combined crowns and single crowns was statistically significant(P＜0.05). The survival rate of short implant in mandible was higher than that in maxilla(P＜0.05).

CONCLUSIONS: Under the standards clinical program and operation, short implant can be used to shorten the implant restoration cycle and avoid complicated bone augmentation which can achieve good long-term clinical effect. Short implant should be used to strictly control the risk factors that affect the survival of short implant.

ABSTRACT

PURPOSE: To verify the efficacy and safety of calcined cattle bone grafting material in filling alveolar bone defect after tooth extraction.

METHODS: A randomized, bind, parallel, positive-control multicenter clinical trial was conducted. A total of 280 subjects were randomly assigned to either the experimental group (calcined cattle bone group) or control group (Bio-Oss group) equally. The main efficacy indicator was the imaging changes 24 weeks after material implantation. Secondary efficacy indicators were wound healing, rejection, bone metabolism, post-filling symptoms and signs of bone infection. The safety of material was assessed by the incidence of adverse events and serious adverse events. SAS 8.2 software package was used for statistical analysis.

RESULTS: A total of 280 cases were included, of them 267 cases completed the study while 13 cases fell off. The effective rate of FAS(PPS) was 90.58%(97.46%) in the experimental group and 87.05% (95.04%) in the control group. The difference of effective rate between the experimental group and control group (95%CI) was 3.53% (-3.88%, 10.94%) of FAS, 2.42% (-2.38%, 7.22%) of PPS, and there was no significant difference between the two groups. The incision healing of the two groups was good, and the incidence of rejection, bone infection signs, post-filling symptoms and bone metabolic changes was very low. The incidence of adverse events was similar in the two groups, and no serious adverse events related to the study materials occurred.

CONCLUSIONS: The efficacy of calcined cattle bone grafting material in filling alveolar bone defect after tooth extraction is not inferior to that of Bio-Oss, and it is safe and effective for alveolar bone defect repair.

ABSTRACT

PURPOSE: To evaluate the effect of combination of auxiliary irrigation technology and root canal irrigation solution in the treatment of chronic apical periodontitis with fistula, and try to seek a more effective and minimally invasive therapeutic strategy.

METHODS: One hundred and fifty patients with fistulous chronic apical periodontitis who were diagnosed in Hefei Stomatological Hospital from January 2021 to January 2022 were randomly divided into 6 groups, 25 cases in each group. The 6 groups were as follows, group A: 0.5%NaOCl +ultrasonically activated irrigation; Group B: 1.0%NaOCl+ultrasonically activated irrigation; Group C: 2.0%CHX+ultrasonically activated irrigation; Group D: 0.5%NaOCl+sonic activation; Group E: 1.0%NaOCl+sonic activation; Group F: 2.0%CHX+sonic activation. The fistula healing time, treatment effect and postoperative pain were observed in each group. The data were analyzed with SPSS 20.0 software package.

RESULTS: In terms of fistula healing, the 10-day fistula healing rate of group E and group F was higher than that of group A and group D，and the difference was statistically significant(P＜0.05); but there was no significant difference between group E and group F (P＞0.05). The effective rate at 1 month after operation in group A was lower, and the difference was significant (P＜0.05). In terms of postoperative pain, the VAS score of group A was lower than that of group E and group F at all time points, and the difference was statistically significant(P＜0.05).

CONCLUSIONS: In the treatment of chronic apical periodontitis with fistula, 1.0% NaOCl or 2.0% CHX combined with ultrasonically activated irrigation or sonic activation obtain a better short-term effect，of which the sonic activation group can also obtain early healing of the fistula, but the incidence of postoperative pain is higher when sonic activation is used.

ABSTRACT

PURPOSE: To analyze the use status and satisfaction of the follow-up patients, and explore the construction of internet medical service model and platform in stomatology.

METHODS: Patients who visited the internet clinic of stomatology from January to June, 2021 were selected. After diagnosis and treatment, they were followed up by AI intelligent voice with self-designed questionnaire. SPSS 21.0 software was used for statistical analysis.

RESULTS: A total of 372 valid questionnaires were collected. The male-to-female ratio of oral patients was 1.25:1, with an average age of 35.96 years. Most of them had a bachelor’s degree or above, and the patients were mainly from the Yangtze River Delta. 53.76% of patients needed doctors to prescribe drugs. 81.72% of the dental patients believed that the consultation process of internet clinic was convenient, and 79.83% of patients perceived that the system operation of internet clinic was convenient. Binary logistic regression showed that digital literacy, convenience of medical treatment process were significantly related to the satisfaction of internet outpatient service, while gender, education level, online medical treatment duration and convenience of system operation were not related.

CONCLUSIONS: Internet medical treatment in stomatology is feasible, but it is still necessary to break through limitations and further innovate service function. Internet outpatients are mainly young and middle-aged, but it is still necessary to care for the special group of the elderly. It is necessary to further optimize the process, upgrade the system and innovate management, strengthen policy support and incentive mechanism, and promote the transformation of medical service mode in stomatology.
