This study aimed to compare the therapeutic efficacy of resection (RES) and microwave ablation (MWA) for hepatocellular carcinoma (HCC) within the Milan criteria.

Between 2011 and 2019, 426 HCC patients within the Milan criteria were treated at our institution (RES n=291; MWA n=135). We compared overall survival (OS), disease-free survival (DFS), complications, and hospital stay in these patients using propensity score matching (PSM) and determined the prognostic factors using multivariate Cox analysis.

Following 11 matching using PSM, 121 patients were matched in each group. The 1-, 3-, and 5-year OS rates were 98.3%, 84.7%, and 69.6% for the MWA group and 96.5%, 81.8%, and 78.1% for the RES group (p=0.667). The corresponding DFS rates for the MWA and RES groups were 81.8%, 54.4%, and 42.3% and 85.4%, 67.8%, and 57.9%, respectively (p=0.174). The MWA group had less blood loss and shorter hospital stays (both p<0.001) than the RES group.

MWA resulted in survival outcomes that were similar to those of RES for HCC within the Milan criteria. However, it had more favorable hospital stay and blood loss outcomes than RES.

However, it is unclear why SCZ patients and high schizotypal (H-SPQ) individuals present a narrower PPS and why the boundaries of the PPS are more sharply defined in patients. We hypothesise that the unusual PPS representation observed in SCZ is caused by an imbalance of excitation and inhibition (E/I) in recurrent synapses of unisensory neurons or an impairment of bottom-up and top-down connectivity between unisensory and multisensory neurons. These hypotheses were tested computationally by manipulating the effects of E/I imbalance, feedback weights and synaptic density in the network. Using simulations we explored the effects of such impairments in the PPS representation generated by the network and fitted the model to behavioural data. We found that increased excitation of sensory neurons could account for the smaller PPS observed in SCZ and H-SPQ, whereas a decrease of synaptic density caused the sharp definition of the PPS observed in SCZ. We propose a novel conceptual model of PPS representation in the SCZ spectrum that can account for alterations in self-world demarcation, failures in tactile discrimination and symptoms observed in patients.

As a result of the rapid spread of the disease caused by severe acute respiratory syndrome coronavirus 2, the World Health Organization declared a global pandemic on March 11, 2020. Governments worldwide adopted various measures to stop or slow the spread of coronavirus disease 2019 (COVID-19). One widely used measure was lockdown; workers who could work from home were instructed to do so, and nonessential businesses-including dental clinics-were closed for weeks or months. The purpose of this investigation was to document the incidence of fixed orthodontic appliance failures and the periodontal health status of patients undergoing fixed orthodontic treatment during and after the lockdown period.

The sample comprised 350 orthodontic patients (mean age, 16.85±2.59years; 249 female, 101 male) who underwent orthodontic and periodontal examinations in Adıyaman, Turkey, after a mean lockdown period of 103.7±21.3days. Frequencies of an orthodontic bracket, elastic ligature, molar band, and miniscrew failures of periodontal health status of the patients.

This study aimed to investigate the effects of the strong occlusal force on the hemodynamics of gingival microcirculation.

Eleven adult volunteers with healthy periodontium and normal occlusion participated in this study. CIL56 solubility dmso Using a noncontact laser Doppler flowmeter placed at the attached gingiva and the interdental papilla of the maxillary first premolar, changes in gingival blood flow (GBF) were examined during and after clenching.

When the strong occlusal pressure was applied on the maxillary first premolar by clenching, GBF in the attached gingiva on the buccal side decreased significantly compared with the resting GBF, with medians of 2.3mL/min/100g and 5.4mL/min/100g, respectively (P<0.05). After the release of the maximum clenching, GBF recovered immediately and transiently increased to a median of 2.4mL/min/100g, showing a significant difference to the resting GBF (P<0.05). In contrast, in the interdental papilla, no significant change in GBF was found by clenching.

The study aimed to evaluate the content and quality of information offered by YouTube for patients seeking information related to orthodontic retainers.

YouTube was searched using the keyword "orthodontic retainers" from Google Trends. From the first 120 results, 97 videos were selected to be analyzed. Videos were rated for quality by video information and quality index (VIQI) and the global quality scale (GQS). Videos were classified as low- and high-content groups using a 10-point score considering several retainer-related topics. Mann-Whitney U tests, chi-square tests, and Pearson correlation coefficients were used for statistical evaluations.

Most YouTube videos were uploaded by dentists/specialists (62.9%). We classified 12 videos as high content and 85 as low content. Instructions on the use of the orthodontic retainer was the most commonly covered topic (42.3%), followed by the effect on oral hygiene (38.1%), definition (37.1%), procedure of preparing orthodontic retainers (33.0%), and procedure of positioning (30.9%). A lower percentage of videos (6.2%) mentioned soft tissue irritation. The high-content video group had a significantly higher median value of GQS score and VIQI (P<0.001). The correlation between GQS and VIQI was strong (r=0.698; P<0.01).

The content of YouTube videos for orthodontic retainers could not be considered as an adequate source of information for patients on orthodontic retainers. Most videos included instructions on the use of orthodontic retainers, but fewer videos mentioned the effect on speech performance and soft tissue irritations.

This randomized clinical trial aimed to compare the skeletal and dental effects of miniscrew-anchored maxillary protraction (MAMP) using hybrid hyrax (HH) and conventional hyrax (CH) expanders in growing patients with Class III malocclusion.

This was a randomized, parallel, controlled trial. Forty growing patients with Class III malocclusion and maxillary deficiency (Wits appraisal of less than -1mm) were randomized into 2 groups. Patients were recruited at the Orthodontic Clinic of Bauru Dental School, University of São Paulo, Brazil. The HH group was composed of patients with Class III malocclusions in the late mixed or early permanent dentition treated with a HH expander with 2 miniscrews in the maxilla and 2 miniscrews in the anterior region of the mandible. Class III elastics were used from the maxillary first molars to the mandibular miniscrews placed between permanent canines and first premolars. The CH group was composed of patients treated with a similar protocol except for the use of a CH expandssoal de Nível Superior, Brasil (CAPES) - Finance Code 001, and by the São Paulo Research Foundation (FAPESP) - Grants nos. 2017/04141-9, 2017/24115-2, and 2019/03175-2.Myocardial infarctions (MI) have been reported in adults with COVID-19. Although MIs are rare in children with COVID-19, cardiac involvement is still possible. In this case report, we present an adolescent with recent COVID-19 infection who presented with an ECG initially suggestive of myocardial infarction (MI). We describe how to differentiate between myocardial infarctions and myopericarditis. A 15-year-old boy, with a history of COVID-19 infection a month prior, presented to the emergency department with fever, abdominal pain, diarrhea, and chest pain. On ECG, he was found to have focal ST-segment elevations in V3 through V6. Given the immediate concern for MI, an emergent echocardiogram was done and showed normal left ventricular systolic function with no regional dyskinesia and normal coronary artery diameters. A repeat ECG showed diffuse ST elevations in the inferior leads and T-wave inversions on V5 and V6, confirming the diagnosis of myopericarditis. In conclusion, multisystem-inflammatory syndrome in children associated with COVID-19 (MIS-C) is a new entity describing a post-infectious inflammatory response in children with prior COVID-19 exposure. Cardiac involvement can include myopericarditis. Initial ECGs may show ST-changes suggestive of MI. However, serial ECGs and echocardiograms can differentiate between MI and myocarditis/myopericarditis. Even with COVID-19, MIs are extremely rare in children, and it is important to be aware of MIS-C and its cardiac complications.An orderly and effective vaccination campaign is essential in combating the global COVID-19 pandemic. As one of the pioneers, the U.S. Center for Disease Control proposes a phased plan to promote the vaccination process. This plan starts with vaccinating the high-priority population in Phase 1, then turns to the remainder of the public in Phase 2, and ends with a scale-back network in Phase 3. The phased plan not only provides a sense of hope to impacted communities that this global pandemic can be defeated, but can serve as a template for other countries. To enhance this plan, this paper develops a generalizable framework for designing a hub-and-spoke vaccination dispensing network to achieve the goals in the Phase 2, which aims to expand the vaccination coverage for the general public. We introduce a new coverage index to measure the priority of different potential dispensing sites based on geo-data and develop an optimization model for network design. The hub-and-spoke network enhances the accessibility of the vaccines to various communities and helps to overcome the challenges related to ultra-cold storage facility shortage. A case study of Middlesex County in New Jersey is presented to demonstrate the application of the framework and provide insights for the Phase 2. Results from the baseline scenario show that increasing the driving time limit from 10 min to 25 min can improve the total coverage index from 40.8 to 55.9. Additionally, we explore how the changes of parameters impact the network design and discuss potential solutions for some special cases. When we allow 4 outreach nodes per hub, all potential 45 outreach points can be covered in the vaccination network within a 20-minute drive, and the total coverage index reaches its maximum value of 58.3.The poultry red mite (Dermanyssus gallinae; PRM) is a blood-sucking ectoparasite of chickens that is a threat to poultry farming worldwide and significantly reduces productivity in the egg-laying industry. Chemical acaricides that are widely used in poultry farms for the prevention of PRMs are frequently ineffective due to the emergence of acaricide-resistant PRMs. Therefore, alternative control methods are needed, and vaccination is a promising strategy for controlling PRMs. A novel adipocyte-plasma membrane-associated protein-like molecule (Dg-APMAP) is highly expressed in blood-fed PRMs according to a previous RNA sequencing analysis. Here, we attempted to identify the full sequence of Dg-APMAP, study its expression in different life stages of PRMs, and evaluate its potential as a vaccine antigen. Dg-APMAP mRNA was expressed in the midgut and ovaries, and in all life stages regardless of feeding states. Importantly, in vitro feeding of PRMs with plasma derived from chickens immunized with the recombinant protein of the extracellular region of Dg-APMAP significantly reduced their survival rate in nymphs and adults, which require blood meals.
