Aims: Perineural invasion (PNI) is associated with survival in oral cavity squamous cell carcinoma (OCSCC). There is evidence to suggest that PNI location and extent may be of additional significance. The primary aim of this study was to evaluate the prognostic ability of PNI, including location and extent, in early-stage OCSCC.

Methods: A retrospective cohort study of 342 OSCC patients undergoing primary surgical treatment was conducted.
An inflammation-resolving polysialic acid-decorated PLGA nanoparticle (PolySia-NP) has been developed to treat geographic atrophy/age-related macular degeneration and other conditions caused by macrophage and complement over-activation. While PolySia-NPs have demonstrated pre-clinical efficacy, this study evaluated its systemic and intraocular safety. PolySia-NPs were evaluated in vitro for mutagenic activity using strains and , with and without metabolic activation; cytotoxicity was evaluated based on its interference with normal mitosis.

The objective of this study was to evaluate the prognostic ability of worst pattern of invasion-5 (WPOI-5) defined by the presence of satellite nodules, extratumoural perineural invasion (PNI) and/or extratumoural lymphovascular space invasion (LVI) in low-stage, node negative OCSCC.
Methods: This was a retrospective study of 160 patients with T1/T2N0 tumours staged using TNM7 treated surgically.
Purpose: To evaluate the impact of modifying the abicipar pegol (abicipar) manufacturing process on the safety and treatment effect of abicipar in patients with neovascular age-related macular degeneration (nAMD).
Methods: A new process for manufacturing abicipar was developed to reduce host cell impurities. In a prospective, Phase 2, multicenter, open-label, 28-week clinical trial, patients (n=123) with active nAMD received intravitreal injections of abicipar 2 mg at baseline (day 1) and weeks 4, 8, 16, and 24.
Background: Pathological margin assessment is an essential component of surgical management of oral cavity squamous cell carcinoma (OCSCC), however, in many studies, variable definitions of involved margins have been used. The purpose of the present study was to compare the prognostic ability of involved margins according to Royal College of Pathologists (RCPath) and College of American Pathologists (CAP) guidance.
Methods: Retrospective study of 300 patients with previously untreated OCSCC undergoing definitive surgical management.
Children with abdominal pain are frequently seen in emergency departments. Physicians and parents worry about appendicitis; physicians are also concerned about intussusception and bowel obstruction in patients with previous surgical procedures. Sometimes the patient is ill, and the diagnosis is elusive.

Methods: A prospective cross sectional study was carried out in two university hospitals examining the pre-operative protocols for patients undergoing otolaryngology surgery and the incidence of COVID-19 within 30 days of surgery in patients and the otolaryngologists performing surgery.
Results: One hundred and seventy-three patients were recruited.

Purpose: The precise etiopathogenesis of human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC), and reasons for predilection for crypt epithelium, remain uncertain. The purpose of this study is to investigate the interaction between HPV and specific cytokeratins 7 (CK7) and 19 (CK19) in crypt epithelium.
Methods: This is a retrospective cohort study of patients presenting between 1999 and 2015 at a tertiary referral center.
Background: Concerns have emerged regarding infection transmission during flexible nasoendoscopy.
Methods: Information was gathered prospectively on flexible nasoendoscopy procedures performed between March and June 2020. Patients and healthcare workers were followed up to assess for coronavirus disease 2019 development.
Purpose: To report the end-of-study results from the Ladder clinical trial of the Port Delivery System with ranibizumab (PDS) for the treatment of neovascular age-related macular degeneration (nAMD).
Design: Multicenter, randomized, active treatment-controlled phase 2 clinical trial.
Participants: Patients diagnosed with nAMD with a documented response to anti-vascular endothelial growth factor treatment who received study treatment (N = 220).
Background: Two major changes to the staging of oral cavity squamous cell carcinoma (OCSCC) were adopted in TNM8: (1) depth of invasion is now used for T staging and (2) extranodal extension for N staging. The aim of this study was to evaluate if TNM8 stratifies OCSCC patients more accurately than TNM7 based on overall survival (OS) statistics and hazard discrimination.
Methods: Retrospective study of 297 patients with OCSCC who underwent surgery at our institution.
Introduction: While positive surgical margins in oral squamous cell carcinoma (OSCC) is generally considered an adverse prognosticator, the significance of close (≤5 mm) margins is more debatable, and has not been widely adopted as an indicator for radiotherapy.
Materials And Methods: Retrospective study of 244 patients undergoing primary surgical resection of OSCC. The impact on local control (LC), disease-specific survival (DSS) and overall survival (OS) of margins at 1 mm intervals was studied.
Objectives: There is no consensus on the optimal approach to human papilloma virus (HPV) testing in oropharyngeal squamous cell carcinoma (OPSCC). Our objective was to classify OPSCC as HPV positive or negative based on (1) morphology alone, (2) p16 status alone, (3) combined morphology and p16 status with additional HPV testing in discordant cases in keeping with 2012 College of American Pathologists (CAP) guidelines (combined approach), and to evaluate and compare survival outcomes.
Materials And Methods: Retrospective review of 168 patients, 146 with OPSCC and 22 with cervical SCC of unknown primary site (SCCUP).
This study investigated the effects of cow's milk on recovery from repeated simulated team games (STGs) in females. Twenty female team-sport athletes completed an STG circuit (2x ~ 30 min, with 10 min 'half-time'). Measures of muscle function, soreness and tiredness, symptoms of stress and serum markers of muscle damage and oxidative stress were determined pre- and 24 h, 48 h, 72 h and 96 h following the circuit.

The curriculum for nurse practitioner (NP) students often overlooks the assessment of the oral cavity. In recognition of this, the HEENT (head, eyes, ears, nose, and throat) assessment was expanded to HEENOT (head, ears, eyes, nose, oral, and throat) through integration of an interprofessional educational (IPE) activity developed for University of Colorado NP and dental students. The aim of this study was to assess NP students' perceptions of an IPE activity in which dental faculty and students taught NP students how to conduct an oral exam, recognize oral health pathology, and apply fluoride varnish.
