Most of the papers originated from the USA (n=21) and Brazil (n=18). Randomized trials were the most common study design (n=32), and "pulpotomy" was the most frequently used keyword (n=35). Poisson regression showed that the number of citations decreased by 1.5% each year, and increased by 9.7% for each unit of impact factor. This bibliometric analysis highlighted papers, authors, and institutions that have contributed to endodontic therapy in primary teeth. Common terms of interest in this research area was also identified, representing the first bibliometric analysis on this subject.PAR1 is a G-coupled protein receptor that regulates several cellular metabolism processes, including differentiation and proliferation of osteogenic and cementogenic related cells and our group previously demonstrated the regenerative potential of PAR1 in human periodontal ligament stem cells (hPDLSCs). In this study, we hypothesized that PAR1 regulates the cementogenic differentiation of hPDLSCs. Our goal was to identify the intracellular signaling pathway underlying PAR1 activation in hPDSLC differentiation. hPDLSCs were isolated using the explant technique. Cells were cultured in an osteogenic medium (OST) (α-MEM, 15% fetal bovine serum, L-glutamine, penicillin, streptomycin, amphotericin B, dexamethasone, and beta-glycerophosphate). The hPDLSCs were treated with a specific activator of PAR1 (PAR1 agonist) and blockers of the MAPK/ERK and PI3K pathways for 2 and 7 days. The gene expression of CEMP1 was assessed by RT-qPCR. The activation of PAR1 by its agonist peptide led to an increase in CEMP1 gene expression when compared with OST control. MAPK/ERK blockage abrogated the upregulation of CEMP1 gene expression induced by PAR1 agonist (p 0.05). We concluded that CEMP1 gene expression increased by PAR1 activation is MAPK/ERK-dependent and PI3K independent, suggesting that PAR1 may regulate cementogenetic differentiation of hPDLSCs.This study aimed to determine the impact of the COVID-19 pandemic on sleep quality and possible sleep bruxism (SB) in children eight to ten years of age. The study hypothesis was that sleep disturbances influenced a higher occurrence of bruxism during the COVID-19 pandemic. this website A longitudinal study was conducted at two time points in person prior to the COVID-19 pandemic (T1), and online during the pandemic (T2). The sample comprised 105 children. Parents/caregivers answered a questionnaire addressing sociodemographic characteristics, the use of electronic devices, reported (vs. clinical) SB, and the Sleep Disturbance Scale for Children (SDSC) at both T1 and T2. McNemar's and Wilcoxon's tests were used to compare SB and sleep disorders at both time points. Poisson regression analysis determined the relative risk (RR) among the variables, and the incidence of possible SB (p≤0.05). The comparison of the two time points (T1 and T2) revealed a significant increase in possible SB (p less then 0.01) and sleep disorders (p less then 0.04). Children whose parents had a lower schooling level (RR 2.67; 95%CI 1.19-6.01), those with their own electronic devices (RR 1.97; 95%CI 1.09-2.50), and those with sleep disorders during the pandemic (RR 1.74; 95%CI 1.35-2.24) were at greater risk of developing SB during the pandemic. Moreover, the incidence of bruxism and sleep disorders was greater during the pandemic. The factors influencing SB incidence during the pandemic were a lower level of mothers' schooling, greater access to electronic devices, and the occurrence of sleep disorders.
The aim of this study was to investigate the frequency of aortic arch anomaly in COVID-19 patients and to determine whether it will be included in the risk classification.
The study was retrospectively conducted in a third-level hospital by scanning the contrast-enhanced thoracic computed tomography and thoracic computed tomography angiography examinations of patients who received PCR (+), hospitalization, and known COVID pneumonia between March 2020 and July 2021. The study consists of 88 cases and 88 control groups.
The study found that the frequency of aortic arch anomaly was higher in patients with COVID-19 pneumonia and in male patients with bovine-type anomaly.
The higher prevalence of bovine arch anomaly in COVID patients may be considered a risk factor for COVID-19 in individuals with this type of vascular anomaly.

In multicentric/multifocal breast tumors, there may be immunological and histological differences between foci that may affect survival and treatment choice. We aimed to evaluate the effect of focal heterogeneity seen in multicentric/multifocal breast tumors on survival.
We retrospectively collected and analyzed the clinicopathological data of 89 female patients with multifocal/multicentric breast cancer, whose surgical and medical treatment was completed and who were followed up for 5 years.
Of all patients, 29.2% (26/89) were heterogeneous. Heterogeneity of these foci was as follows histologic heterogeneity of index foci (mix type) 15.7% (14/89), histologic heterogeneity of inter-foci 7.9% (7/89), and immunohistochemical heterogeneity of inter-foci 10.1% (9/89). When additional foci were evaluated, oncological therapy was changed for 3 (3.3%) of 89 patients. Heterogeneity does not have a significant (p>0.05) effect on recurrence and survival in multicentric/multifocal breast cancers. Pathological N stage is an independent risk factor for disease-free survival (hazard ratio=2.29, 95% confidence interval=1.39-3.76, p=0.001).
In multifocal/multicentric breast cancers, less than 4% of patients may experience heterogeneity requiring change in the therapeutic decision. However, heterogeneity does not have a significant effect on recurrence and survival in multifocal/multicentric breast cancers. The pathological N stage is an independent risk factor for disease-free survival.

Thyroid neoplasm incidence has increased worldwide, mostly due to the advancements in medical imaging and screening rates. The aberrant Wnt/β-catenin pathway has been identified as a key mechanism, and it has also been related to the metastatic activity of differentiated thyroid cancer. We aimed to verify the difference in the expression of Wnt3a, a canonical activator of the β-catenin signaling, and CDX-2, a transcription factor upregulated by Wnt/β-catenin pathway, in multinodular goiter and differentiated thyroid cancer and to determine their prognostic value.
We included 194 thyroid tissue surgical specimen and their clinicopathological data study group (differentiated thyroid cancer, n=154) and control group (multinodular goiter, n=40). Immunohistochemistry (IHC) was performed on formalin-fixed, paraffin-embedded tissue by the primary antibodies Wnt3a and CDX-2.
High Wnt3a expression was significantly associated with differentiated thyroid cancer (p=0.031). CDX-2 was negative in all differentiated ular-derived lesions.
The aim of this study was to explore the efficacy of imipenem combined with glutamine in the treatment of severe acute pancreatitis with abdominal infection in mainland China using meta-analysis.
We searched China National Knowledge Network, Wanfang Medical Network, Chinese Science Citation Database, PubMed, and Embase Databases for publications of imipenem combined with glutamine in the treatment of severe acute pancreatitis abdominal infection. The search time limit was from the establishment of the database to April 10, 2021. Stata software version 12.0 was used for statistical analysis; the combined effect size odds ratio and standardized mean difference values were calculated for the count data and measurement data, respectively; and the heterogeneity test was performed in this study.
A total of five randomized controlled trials were included. A total of 499 cases were included, with 251 in the observation group and 248 in the control group. Meta-analysis results showed that the efficacy of imipenem combined with glutamine in the treatment of severe acute pancreatitis with abdominal infection was significantly better than that of imipenem alone (odds ratio=0.78, 95%CI 0.71-0.86, p=0.040).
Imipenem combined with glutamine can significantly improve the efficacy in the treatment of severe acute pancreatitis with abdominal cavity infection.

The aim of this study was to evaluate the anxiety experienced by health care workers in different branches during the COVID-19 pandemic.
The cross-sectional study included 373 health care workers. Data were collected using an online questionnaire consisting of the Sociodemographic Form (32 items related to the working conditions of health care professionals during the COVID-19 pandemic) and the Penn State Concern Questionnaire.
The anxiety levels of the female workers were significantly higher (p<0.001). The total Penn State Concern Questionnaire points were determined to be statistically significantly higher in those who need to protect the family during the pandemic (p=0.03), who were dissatisfied with their profession (p<0.001), and those whose workload had increased during the pandemic (p=0.007).
The study results demonstrated that the levels of anxiety of health care workers during the COVID-19 pandemic could be increased by young age, low level of experience, female gender, increased workload, and dissatisfaction with the profession.

The CHA2DS2-VASc score is used to determine thromboembolic risk in cases of atrial fibrillation. The predictive value of this score in predicting coronary collateral circulation in chronic total occlusion is unknown.
The aim of this study was to investigate the relationship between the CHA2DS2-VASc score and coronary collateral circulation in patients with chronic total occlusion.
A total of 189 patients, who underwent coronary angiography and had a chronic total occlusion in at least one coronary artery, were enrolled in this study. The Rentrop scoring system was used for grouping the patients, and patients were classified as having poorly developed coronary collateral circulation (Rentrop grade 0 or 1) or well-developed coronary collateral circulation (Rentrop grade 2 or 3).
The CHA2DS2-VASc score of the good coronary collateral circulation group was significantly lower than the other group (3.1±1.7 vs. 3.7±1.7, p=0.021). During the follow-up period, 30 (32.2%) patients in the poorly developed coronary collateral circulation group and 16 (16.
