We thank the authors for their response to our recent publication titled "Role of structures in the masticator space in selecting patients with resectable T4b oral cancer: findings from a survival analysis"".1 We understand the concerns raised by the authors regarding the structures involved in the masticator space and their utility in assessing the resectability of advanced oral cancers, and our paper clearly elucidates their significance.

Estimation of the COVID‐19 Mean Incubation Time: Systematic Review, Meta‐analysis, and Sensitivity Analysis

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Objectives

Providing sensible estimates of the mean incubation time for COVID-19 is important yet complex. This study aims to provide sensible estimates of the mean incubation time of COVID-19 by capitalizing on available estimates reported in the literature and exploring different ways to accommodate heterogeneity involved in the reported studies.

Methods

Online databases between January 1 of 2020 and May 20 of 2021 are first searched to obtain estimates of the mean incubation time of COVID-19 from available studies, and meta-analyses are then conducted to generate synthetic estimates. Heterogeneity of the studies is examined via the use of Cochran's Q statistic and Higgin's & Thompson's I2 statistic, and subgroup analyses are conducted using mixed effects models. The publication bias issue is assessed using the funnel plot and Egger's test.

Results

Using all those reported mean incubation estimates for COVID-19, the mean incubation time is estimated to be 6.43 days with a 95% confidence interval (CI) (5.90, 6.96), and using all those reported mean incubation estimates together with those transformed median incubation estimates, the estimated mean incubation time is 6.07 days with a 95% CI (5.70,6.45).

Conclusions

The reported estimates of the mean incubation time of COVID-19 vary considerably due to multiple reasons, including heterogeneity and publication bias. To alleviate these issues, we take different angles to provide a sensible estimate of the mean incubation time of COVID-19. Our analyses show that the mean incubation time of COVID-19 between January 1 of 2020 and May 20 of 2021 ranges from 5.68 days to 8.30 days.

Use of Saliva and RT‐PCR Screening for SARS‐CoV‐2 Variants of Concern: Surveillance and Monitoring

alexandrossfakianakis shared this article with you from Inoreader

ABSTRACT

Genomic surveillance has been applied since the beginning of the COVID-19 pandemic to track the spread of virus, leading to characterization of multiple SARS-CoV-2 variants, including Variants of Concern (VOC). Although sequencing is the standard method, rapid molecular test for screening and surveillance of VOC is considered for detection. Furthermore, using alternative saliva as specimen collection, facilitates the implementation of a less invasive, self-collected sample. In this study, we applied a combinatory strategy of saliva collection and RT-PCR for SARS-CoV-2 VOC detection. Saliva samples from patients attending at a tertiary hospital with suspected COVID-19 were collected and SARS-CoV-2 RNA was detected using SARS-CoV-2 RT-qPCR reagent kit (PerkinElmer). Positive saliva samples were screened for SARS-CoV-2 VOC with previously described RT-PCR for Alpha, Beta and Gamma variants. Saliva samples were positive in 171 (53%) of 324 tested. A total of 108 (74%) from positive samples were also positive for VOC by RT-PCR screening. Those samples were found between January and August 2021. This approach allowed us to successfully use an alternative and complementary tool to genomic surveillance to monitoring the circulation of SARS-CoV-2 VOC in the studied population.

Glibenclamide promoted functional recovery following sciatic nerve injury

alexandrossfakianakis shared this article with you from Inoreader

Abstract

The impact of peripheral nerve damage on a patient's quality of life is severe. The most frequent peripheral nerve crush damage is a sciatic nerve injury. Previous research has shown that glibenclamide (GB) has neuroprotective properties in a variety of oxidative stress-related disorders, including Alzheimer and Parkinson. The goal of this study was to see how GB affected nerve regeneration and improved function of the sciatic nerve in a rat model following a crush injury. We evaluated motor function, sensory recovery, gene expression, and histomorphometry following damage at different time points. Additionally, we assessed atrophy in the gastrocnemius muscle using histology and mass ratio analyses. Our results suggest that 2-, 4-, 6-, and 8-weeks following glibenclamide therapy, promotes the recovery of motor and sensory function in the injured site. Following glibenclamid injection, the mRNA levels of neurotrophic factors (NGF and BDNF) are raised. According to histomorphometry assessment, glibenclamide injection also increased the number of myelinated fibers while decreasing their thickness. These results showed that glibenclamide therapy by decreasing the proinflammatory and oxidant factors may enhance the nerve regeneration. It is clear that more research is needed to confirm these findings.

Clinical considerations in the surgical management of peri‐implantitis lesions in the esthetic zone

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Objective

The treatment of peri-implantitis is commonly associated to soft tissue changes as part of disease resolution. These changes may alter harmony in the esthetic area, and thus may negatively affect patient satisfaction. This technical note presents the key features that may lead to an unsatisfactory esthetic outcome when managing peri-implantitis in the anterior zone.

Clinical Significance

It is essential to consider four pivotal elements in securing therapeutic success through the resolution of inflammation while maintaining esthetics: (1) patient-related factors, including patient willingness to treat and the smile line; (2) implant-related factors that influence implant position; (3) site-related factors related to defect configuration; and (4) prosthetic-related factors referred to the prosthetic emergence profile and the type of prosthesis. A comprehensive examination must be carried out preoperatively to assess the impact of the surgical treatment upon the esthetic outcomes.

Conclusion

The clinician must be aware of the key features that condition the esthetic outcome when managing peri-implantitis.
