ABSTRACT

Objective:To explore the diagnostic value of American Society of Radiology Thyroid Imaging Reporting and Data System（ACR-TIRADS） and Chinese Thyroid Nodule Ultrasound Malignant Risk Stratification（C-TIRADS） in nodular Hashimoto thyroiditis and papillary thyroid carcinoma with Hashimoto thyroiditis. Methods:This retrospective analysis included 144 patients（204 thyroid nodules） accompanied by nodular Hashimoto thyroiditis or papillary thyroid carcinoma under the background of Hashimoto thyroiditis confirmed by surgical pathology examination in the First Affiliated Hospital of Hebei North University from August 2018 to May 2021, all nodules were examined by ultrasound, and 204 nodules were scored and graded according to the classification standards of ACR-TIRADS and C-TIRADS. The surgical pathological results were the gold standard. The receiver operating characteristic curve of ACR-TIRADS and C-TIRADS was constructed to evaluate and compare the diagnostic performance of the two guideline. Results:①Ultrasound feature results showed that nodular Hashimoto thyroiditis and Papillary thyroid carcinoma had statistically significant differences in the location, echogenicity, calcifications and margins（P<0.001）, but there is no significant difference in structure and aspect ratio between the two kinds of nodular（P=0.141, P=0.240）; nodular Hashimoto thyroiditis were mostly absent focal echogenicity and hyperechogenicity, while papillary thyroid carcinoma was mostly manifested as focal echogenicity and extrinsic thyroid invasion. ②The sensitivity and negative predictive value of C-TIRADS were 91.7% and 83.1%, respectively, which were higher than those of ACR-TIRADS, and the difference was statistically significant（P=0.021, P=0.013）; The specificity and positive predictive value of C-TIRADS T were 98.3% and 99.2%, both of which were slightly higher than ACR-TIRADS, althought the difference was not statistically significant（P=0.157, P=0.062）. The area under the curve of the ACR-TIRADS and C-TIRADS were 0.806 and 0.941, respectively, and the difference was statistically significant（P=0.031）. ③The unnecessary FNAB rate of C-TIRADS was 10.3%, which was lower than ACR-TIRADS. Conclusion:C-TI-RADS has a better diagnostic value of nodular Hashimoto thyroiditis and thyroid papillary carcinoma under the background of Hashimoto thyroiditis, which is helpful for clinical evaluation of such nodules.

ABSTRACT

Proximal humerus fractures represent one of the most common fractures in the elderly, and are increasingly treated with surgical fixation. Suture augmentation attaching the rotator cuff to the plate has been advocated to combat varus collapse and other associated complications. The objective of this study was to evaluate the contribution of rotator cuff augmentation to stability of proximal humerus fracture fixation. Twelve shoulder specimens from six cadavers underwent simulated two-part and three-part proximal humerus fractures. Matched specimens from the same cadaver were randomized to suture augmentation with locking plate fixation vs. locking plate fixation alone. Greater tuberosity fragment displacement was recorded during cyclic rotational strain of the glenohumeral joint. Greater tuberosity displacement in the two-part fracture model trended towards greater motion without suture augmentation, but did not reach statistical significance (0.032 + 0.012 mm vs. 0.213 + 0.109 mm, p = 0.130). In the three-part fracture model, there was a statistically significant decrease in fracture displacement in the presence of suture augmentation (0.068 + 0.025 mm vs. 2.392 + 0.373 mm, p < 0.001). No specimens demonstrated premature failure during cyclic loading. Suture augmentation of locking plate fixation of three-part proximal humerus fractures results in decreased fracture displacement than locked plating alone, during rotational stresses simulating in vivo rotator cuff deformation forces.

ABSTRACT

Proximal humerus fractures (PHF) are common in elderly and osteoporotic patients, and these fractures are often described using the Neer classification. As reverse shoulder arthroplasty (RSA) for PHF becomes more common, it is helpful to identify the utility of Neer classification in predicting postoperative outcomes for patients undergoing RSA. The medical records of patients undergoing primary RSA for PHF at a single academic institution from 2013-2019 were identified using medical billing codes. A multivariable logistic regression analysis identified independent factors associated with all cause 90-day readmissions, reoperation, and length of stay (LOS) greater than three days. Fifty-five patients (average age of 72.3 ± 8.6 years) were included. No statistically significant differences among two-, three-, and four-part fractures with regard to LOS, discharge location, 90-day readmission, revision surgery, postoperative dislocation, or deep infection were detected. These findings suggest that Neer classification for PHF is not predictive of short-term complications after RSA. (Journal of Surgical Orthopaedic Advances 31(2):104-108, 2022).

ABSTRACT

Varicella is a contagious disease of children. Qingdao administrated free one-dose and free two-dose universal varicella vaccination schedules in 2013 and 2016 for preschool children. The effectiveness of the vaccination was analyzed in this study. Monthly varicella incidence data of 1-6 years old children during 2007-2020 were obtained from the Qingdao Infectious Disease Reporting Information Management System. We applied Interrupted time series and segmented regression analyses to assess changes in varicella incidence at the beginning of each month and average monthly changes during the vaccination. The vaccination was associated with a reduction of 32.7% in varicella morbidity on average during the 8-year intervention, there is a statistically significant difference between the voluntary period and free vaccination period (χ² = 290.80,P < 0.001). Immediately after the free one-dose vaccination implementation in 2013 and free two-dose vaccination implementation in 2016, varicella incidence decreased by 0.135 cases per 100 000 population (P < 0.001) and increased by 1.189 cases per 100 000 population (P = 0.039), respectively, the results were statistically significant. There were significant declining trends in varicella incidence after free vaccination: 0.135(P < 0.001) and 0.055 (P = 0.025) per month in 2013.7-2016.6 and 2016.7-2020.12, respectively. This study shows a further decaying trend of varicella incidence based on the impact of free two-dose vaccination. It is necessary to prolong free two-dose universal varicella vaccination to strengthen the immune barrier of preschool children sequentially.

ABSTRACT

INTRODUCTION: This report details the approach taken to providing a dataset allowing for analyses on the performance of recently developed assays of amyloid beta (Aβ) peptides in plasma and the extent to which they improve the prediction of amyloid positivity.

METHODS: Alzheimer’s Disease Neuroimaging Initiative plasma samples with corresponding amyloid positron emission tomography (PET) data were run on six plasma Aβ assays. Statistical tests were performed to determine whether the plasma Aβ measures significantly improved the area under the receiver operating characteristic curve for predicting amyloid PET status compared to age and apolipoprotein E (APOE) genotype.

RESULTS: The age and APOE genotype model predicted amyloid status with an area under the curve (AUC) of 0.75. Three assays improved AUCs to 0.81, 0.81, and 0.84 (P < .05, uncorrected for multiple comparisons).

DISCUSSION: Measurement of Aβ in plasma contributes to addressing the amyloid component of the ATN (amyloid/tau/neurodegeneration) framework and could be a first step before or in place of a PET or cerebrospinal fluid screening study.

HIGHLIGHTS: The Foundation of the National Institutes of Health Biomarkers Consortium evaluated six plasma amyloid beta (Aβ) assays using Alzheimer’s Disease Neuroimaging Initiative samples. Three assays improved prediction of amyloid status over age and apolipoprotein E (APOE) genotype. Plasma Aβ42/40 predicted amyloid positron emission tomography status better than Aβ42 or Aβ40 alone.

ABSTRACT

BACKGROUND: Individuals diagnosed with COVID-19 are instructed to self-isolate at home. However, during self-isolation, they may experience anxiety and insufficient care. Patient portals can allow patients to self-monitor and share their health status with healthcare professionals for remote follow-up, but little data is available on the feasibility of their use.

OBJECTIVE: This manuscript presents the protocol of the Opal-COVID Study which has four objectives: 1) assess the implementation of using the Opal patient portal for distance monitoring of COVID-19 patients self-isolating at home; 2) identify influences on the intervention’s implementation; and describe 3) service and 4) patient outcomes of this intervention.

METHODS: This mixed-method pilot study aims to recruit 50 COVID-19 patient participants tested at the McGill University Health Centre (Montreal, Canada) for 14 days of remote follow-up. With access through a smartphone app to an existing patient portal configured for this study, patients will complete a daily self-assessment of symptoms, vital signs, and mental health, monitored by a nurse, and receive teleconsultations, as needed. Study questionnaires will be administered to collect data on sociodemographic characteristics, medical background, implementation outcomes (acceptability, usability, and respondent burden) and patient satisfaction. Coordinator logbook entries will inform on feasibility outcomes, namely, recruitment/retention rates and fidelity, as well as on the frequency and nature of contacts with healthcare professionals via Opal. The statistical analyses for Objectives 1 (implementation outcomes), 3 (service outcomes), and 4 (patient outcomes) will evaluate the effects of time and sociodemographic characteristics on the outcomes. For Objectives 1 (implementation outcomes) and 4 (patient outcomes), the statistical analyses will also examine the attainment of predefined success thresholds. As to the qualitative analyses, for Objective 2 (influences on implementation), semi-structured qualitative interviews will be conducted with four groups of stakeholders (i.e., patient participants, healthcare professionals, technology developers and study administrators) and submitted to content analysis, guided by the Consolidated Framework for Implementation Research to help identify barriers and facilitators of implementation. For Objective 3 (service outcomes), reasons for contacting healthcare professionals through Opal will also be submitted to content analysis.

RESULTS: Between December 2020 and March 2021, 51 patient-participants were recruited. Qualitative interviews were conducted with 39 involved stakeholders, from April to September 2021. Delays were experienced due to measures taken at the MUHC to address COVID-19. The quantitative and qualitative analyses began in May 2022. As of June 2022, two manuscripts (respectively on the implementation and the patient outcomes) were being prepared and three conference presentations had been given on the study’s methods.

CONCLUSIONS: This protocol is designed to generate multidisciplinary knowledge on the implementation of a patient portal-based COVID-19 care intervention and will lead to a comprehensive understanding of feasibility, stakeholder experience, and influences on implementation that may prove useful for scaling up similar interventions.

ABSTRACT

BACKGROUND: Crowdfunding is increasingly used to offset the financial burdens of illness and healthcare. In the era of the COVID-19 pandemic and associated infodemic, the role of crowdfunding to support controversial COVID-19 stances is unknown.

OBJECTIVE: We sought to examine COVID-related crowdfunding focusing on the funding of alternative treatments not endorsed by major medical entities, including campaigns with an explicit anti-vaccine, anti-mask, or anti-healthcare stances.

METHODS: We performed a cross-sectional analysis of GoFundMe campaigns for individuals requesting donations for COVID-19 relief. Campaigns were identified by keyword and manual review to categorize campaigns into “Traditional treatments”, “Alternative treatments”, “Business-related”, “Mandate”, “First Response”, and “General”. For each campaign, we extracted basic narrative, engagement, and financial variables. Among those that were manually reviewed the additional variables of “mandate type”, “mandate stance” and presence of COVID-19 misinformation within the campaign narrative were also included. COVID-19 misinformation was defined as “false or misleading statements” where cited evidence could be provided to refute the claim. Descriptive statistics were used to characterize the study cohort.

RESULTS: A total of 30,368 campaigns met criteria for final analysis. After manual review, we identified 53 campaigns (0.17%) seeking funding for unproven alternative medical treatment for COVID-19 including popularized treatments: ivermectin (14), hydroxychloroquine (6), and Vitamin D (4). Twenty-three (43%) of the campaigns seeking support for alternative treatments contained COVID-19 misinformation. There were 80 campaigns that opposed mandating masks/vaccination, 48 (60%) of which contained COVID-19 misinformation. Alternative treatment campaigns had a lower median amount raised ($1,135) compared to traditional ($2,828) treatments (p<0.0001) and a lower median percentile of target achieved (11.9% vs 31.1%; p=0.0027). Campaigns for alternative treatments raised substantially lower amounts ($115,000 vs $52,715,000, respectively) and lower proportions of fundraising goals (2.1% vs 12.5%) for alternative versus conventional campaigns. The median goal for campaigns was significantly higher ($25,000 vs $10,000) for campaigns opposing mask/vaccine mandates relative to those in support of upholding mandates (p=0.042). Campaigns seeking funding to lift mandates on health care workers reached $622 out of a $410,000 goal (0.15%). Conversely, funding campaigns seeking assistance for front-line health workers reached goal funding in 13.5% of cases.

CONCLUSIONS: A small minority of online crowdfunding for COVID-19 were directed at unproven COVID-19 treatments and support for campaigns aimed against masking or vaccine mandates. Approximately half of these campaigns contained verifiably false or misleading information and had limited fundraising success. Crowd-sourced campaign funding for unproven COVID-19 beliefs may be attempting to capitalize on and perpetuate ongoing COVID-19 misinformation. It remains unclear how these funds are being spent and therefore to what extent donors are being manipulated based on their COVID-19 views. The ongoing Infodemic will no doubt continue to strain the resources of social media sites including GoFundMe.

ABSTRACT

In October 2021, the Italian Ministry of Health has planned the offer of a booster dose of anti-SARS-CoV-2 vaccine for healthcare workers (HCWs), recommending the simultaneous administration of the third anti-SARS-CoV-2 dose and the influenza vaccine. The immunogenicity and serological response of co-administration are questioned. This is a retrospective cohort pilot study. We evaluated in a sample of HCWs the serological response 1 month after the administration of the third dose, comparing it between subjects who chose for co-administration (Cominarty+Flucelvax) and subjects who preferred the administration of the anti-SARS-CoV-2 vaccine. The study population comprised 20 HCWs, 9 (45.0%) chose co-administration (Group 1), and 11 (55.0%) preferred the administration of the COVID-19 vaccine alone (Group 2). A statistical significant difference of the variation of IgG anti-spike-protein antibodies between the serological evaluation at 1 month after the third dose and the serological evaluation 1 month after the basal routine with Comirnaty between Group 1 (-4,842.9; 95%CI = -15,799.2-6,113.2) and Group 2 (9,258.9; 95%CI = 1,081.0-17,435.9; p-value = 0.029) was reported. New scientific evidences are necessary to clarify this critical issue to guarantee both the best immunogenicity of COVID-19 vaccination and an high vaccine coverage for influenza vaccination.

ABSTRACT

Advances of high throughput experimental methods have led to the availability of more diverse omic datasets in clinical analysis applications. Different types of omic data reveal different cellular aspects and contribute to the understanding of disease progression from these aspects. While survival prediction and subgroup identification are two important research problems in clinical analysis, their performance can be further boosted by taking advantages of multiple omics data through multi-view learning. However, these two tasks are generally studied separately, and the possibility that they could reinforce each other by collaborative learning has not been adequately considered. In light of this, we propose a View-aware Collaborative Learning (VaCoL) method to jointly boost the performance of survival prediction and subgroup identification by integration of multiple omics data. Specifically, survival analysis and affinity learning, which respectively perform survival prediction and subgroup identification, are integrated into a unified optimization framework to learn the two tasks in a collaborative way. In addition, by considering the diversity of different types of data, we make use of the log-rank test statistic to evaluate the importance of different views. As a result, the proposed approach can adaptively learn the optimal weight for each view during training. Empirical results on several real datasets show that our method is able to significantly improve the performance of survival prediction and subgroup identification. A detailed model analysis study is also provided to show the effectiveness of the proposed collaborative learning and view-weight learning approaches.
