Deepening Cisplatin sensitivity on Oral Squamous cell Carcinoma cell lines after PON2 knockdown: A FTIRM investigation.

Cisplatin is a platinum-based chemotherapy drug with antimicrobial and antitumoral activity, largely used for a long time in the treatment of several cancers, including the Oral Squamous Cell Carcinoma (OSCC), which is one of the most frequent neoplasms of the oral cavity. Due to its aggressiveness and metastatic invasion, OSCC is characterized by poor outcome, often related also to chemoresistance mechanisms. The intracellular enzyme paraoxonase-2 (PON2) normally acts defending cells from the damages induced by Reactive Oxygen Species.

Are we ready to use ultrasounds in the clinical assessment of depth of invasion and tumor thickness in oral squamous cell carcinoma? Results from a systematic review, meta-analysis and trial sequential analysis.

Objectives: To investigate the accuracy of ultrasound in the quantification of tumor thickness (TT) and depth of invasion (DOI) of oral potentially malignant disorders and oral squamous cell carcinoma.

Materials And Methods: A systematic review search was conducted in PubMed, Scopus, and Web of Science to answer the PICO question: "What is the correlation and the mean difference between ultrasound and histopathological assessment of tumor thickness and depth of invasion in patients with oral squamous cell carcinoma and oral potentially malignant disorders? The risk of bias was assessed, meta-analysis and trial sequential analysis was conducted on the available quantitative data, followed by trial sequential analysis.

Results: Of 2089 results, 48 studies were considered suitable for inclusion.

Modulation of NRF2/KEAP1 Signaling by Phytotherapeutics in Periodontitis.

Periodontitis affects up to 40% of adults over 60 years old and is a consequence of gingivitis. Periodontitis is characterized by a chronic inflammation, periodontal damage, and alveolar bone resorption. The nuclear factor erythroid 2-related factor 2 (NFE2L2 or NRF2)/Kelch-like ECH-Associated Protein 1 (KEAP1) (NRF2/KEAP1) signaling pathway plays a key role in periodontitis by modulating redox balance and inflammation of the periodontium.

Aortic balloon valvuloplasty outcome according to calcium distribution and valve geometry - The ABCD study.

Background: There is little data on the outcome of balloon aortic valvuloplasty (BAV) in relation to valve dimensions and calcification patterns. The procedure is not standardized, particularly the choice of balloon size.

Methods: This retrospective multicenter study focused on BAV efficacy and safety by analyzing the relationship between balloon size, annulus geometry (i.

Biomolecular alterations temporally anticipate microarchitectural modifications of collagen in oral tongue squamous cell carcinoma.

High resolution analysis of collagen bundles could provide information on tumor onset and evolution. This study was focused on the microarchitecture and biomolecular organization of collagen bundles in oral tongue squamous cell carcinoma (OTSCC). Thirty-five OTSCC biopsy samples were analyzed by synchrotron-based phase-contrast microcomputed tomography and Fourier transform infrared imaging (FTIRI) spectroscopy.

Reconstruction of oral mucosal defects with regenerative dermal matrix after T1-T2 squamocellular carcinoma resection.

Objective: Resection of tumors of oral cavity usually causes short- or long-term sequelae such as chewing, speech and swallowing impairment. To preserve this function it is necessary to maintain the lining of the oral cavity, the mobility and sensitivity of the tongue. Reconstructive options for oral mucosal defects resulting from tumor resection included primary closure, mucosal and skin grafts, pedicle and microvascular free flaps, and dermal matrix.

Combinatorial quantification of distinct neural projections from retrograde tracing.

Comprehensive quantification of neuronal architectures underlying anatomical brain connectivity remains challenging. We introduce a method to identify distinct axonal projection patterns from a source to a set of target regions and the count of neurons with each pattern. A source region projecting to n targets could have 2-1 theoretically possible projection types, although only a subset of these types typically exists.

Coronary calcification in patients presenting with acute coronary syndromes: insights from the MATRIX trial.

Aims: The role of coronary calcification on clinical outcomes among different revascularization strategies in patients presenting with acute coronary syndromes (ACSs) has been rarely investigated. The aim of this investigation is to evaluate the role of coronary calcification, detected by coronary angiography, in the whole spectrum of patients presenting with acute ACS.

Methods And Results: The present study was a post hoc analysis of the MATRIX programme.

Complete or Culprit-Only PCI in Older Patients with Myocardial Infarction.

Background: The benefit of complete revascularization in older patients (≥75 years of age) with myocardial infarction and multivessel disease remains unclear.

Methods: In this multicenter, randomized trial, we assigned older patients with myocardial infarction and multivessel disease who were undergoing percutaneous coronary intervention (PCI) of the culprit lesion to receive either physiology-guided complete revascularization of nonculprit lesions or to receive no further revascularization. Functionally significant nonculprit lesions were identified either by pressure wire or angiography.

Oral lichen planus in children: An Italian case series.

Oral lichen planus usually occurs in adults; there are no clear data regarding the incidence and the clinical features of oral lichen planus in children. This paper reports clinical findings, treatments, and outcomes of 13 Italian patients with oral lichen planus in childhood diagnosed between 2001 and 2021. The most common finding was keratotic lesions with reticular or papular/plaque-like patterns, confined to the tongue in seven patients.

Evaluation of antibody response anti SARS-Cov-2: A retrospective observational study (Marche-Italy).

Background: COVID-19 has hit every country in the world. Almost a quarter of a billion cases and nearly 5 million deaths reported globally as of late September 2021. Compared to over 6 billion doses of COVID-19 vaccine administered, the pandemic does not seem to disappear.

Combinatorial quantification of distinct neural projections from retrograde tracing.

Comprehensive quantification of neuronal architectures underlying anatomical brain connectivity remains challenging. We introduce a method to identify the distinct axonal projection patterns from a source to a set of target regions and the count of neurons with each pattern. For a source region projecting to targets, there are 2 - 1 theoretically possible projection types, although only a subset of these types typically exists.

Transient vs In-Hospital Persistent Acute Kidney Injury in Patients With Acute Coronary Syndrome.

Background: The occurrence of acute kidney injury (AKI) among patients with acute coronary syndrome (ACS) undergoing invasive management is associated with worse outcomes. However, the prognostic implications of transient or in-hospital persistent AKI may differ.

Objectives: The aim of this study was to evaluate the prognostic implications of transient or in-hospital persistent AKI in patients with ACS.

Role Played by Paraoxonase-2 Enzyme in Cell Viability, Proliferation and Sensitivity to Chemotherapy of Oral Squamous Cell Carcinoma Cell Lines.

Oral squamous cell carcinoma represents the most aggressive and frequent form of head and neck cancer. Due to drug resistance, the 5-year survival rate of patients with advanced disease is less than 50%. In order to identify molecular targets for effective oral cancer treatment, we focused on paraoxonase-2 enzyme.

A Comparison of Inhaled Epoprostenol in Patients With Acute Respiratory Distress Syndrome and COVID-19-Associated Acute Respiratory Distress Syndrome.

Introduction Acute respiratory distress syndrome (ARDS) and coronavirus disease 2019 (COVID-19)-associated acute respiratory distress syndrome (CARDS) are both characterized by non-cardiogenic pulmonary edema and severe hypoxemia that leads to a high percentage of patients suffering in-hospital mortality. Mechanistically, inhaled epoprostenol (iEPO) has shown a role in the treatment of ARDS and CARDS but little data are available directly comparing the two disease processes. Due to the lack of evidence of iEPO in ARDS and CARDS, the authors sought to compare the pulmonary effects of iEPO for mechanically ventilated patients with CARDS against a case match control of those with ARDS.

Casirivimab/imdevimab treatment for outpatient COVID-19 during a SARS-CoV-2 B1.617.2 (Delta) surge at a community hospital.

Context: Vaccination status has been shown to be linked to patient-centered outcomes in those with COVID-19. However, minimal data have explored the relationship between vaccination status and representation rates after receiving monoclonal antibodies (MABs) the Delta strain of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) in a community setting.

Objectives: The authors sought to determine if there was a difference in patient-centered outcomes between those who were vaccinated and unvaccinated after the administration of casirivimab/imdevimab for mild-to-moderate COVID-19 during the time when the Delta strain was most prevalent.

The Emerging Impact of Tumor Budding in Oral Squamous Cell Carcinoma: Main Issues and Clinical Relevance of a New Prognostic Marker.

Tumor Budding (TB) represents a single cancer cell or a small cluster of less than five cancer cells on the infiltrative tumor front. Accumulating evidence suggests TB is an independent prognostic factor in oral squamous cell carcinoma (OSCC). However, its exact role is not yet elucidated, and a standardized scoring system is still necessary.
