Smartphone Thermal Imaging as an Adjunct to Identify Free Flap Perforators and Assisting Flap Design: A Pilot Study.

Background: The main technique for identification of free flap perforator vessels is Doppler sonography, which is not always accurate, user dependent and affected by the patient's body habitus.

Methods: Adult patients undergoing head and neck resection and free flap reconstruction at two academic institutions were enrolled. Doppler sonography was used to identify perforators, and were marked using a skin marker.

Novel radiogenomics approach to predict and characterize pneumonitis in stage III NSCLC.

Unresectable stage III NSCLC is now treated with chemoradiation (CRT) followed by immune checkpoint inhibitors (ICI). Pneumonitis, a common CRT complication, has heightened risk with ICI, potentially causing severe outcomes. Currently, there are no biomarkers to predict pneumonitis risk or differentiate between radiation-induced pneumonitis (RTP) and ICI-induced pneumonitis (IIP).

A Mobile Craniofacial Surgery Unit: Reconstructing Casualties of War in Ukraine.

This paper describes the development and implementation of a mobile craniofacial surgical unit designed to address complex posttraumatic craniofacial deformities in both civilian and military casualties resulting from Russia's invasion of Ukraine. Restricted air space, limited possibilities for transportation of personnel and equipment, frequent interruption of power and water supply, and constant threat of injury to patients and medical personnel from missile and drone strikes, precludes reliable and safe delivery of tertiary care. The Canada Ukraine Surgical Aid Program (CUSAP) addressed these challenges by establishing a mobile craniofacial surgery unit, operating just outside of the war zone.

Surgical Margin Definition and Assessment in Head and Neck Oncology: A Cross-Sectional Survey of Canadian Head and Neck Surgeons.

Importance: Head and neck squamous cell carcinomas (HNSCC) are responsible for a significant amount of morbidity and mortality in Canada. Surgical margins are one of the most important factors used to guide treatment; however, currently there is a lack of consensus on the ideal surgical margin definition, sampling, and assessment method.

Objective: To understand the current perspectives and practice patterns of Canadian head and neck surgeons with respect to surgical margin: (1) definition, (2) sampling, (3) pathological assessment.

Using EMS data to explore community-level factors associated with firearm violence in North Carolina.

Background: Firearm violence is a significant public health issue. However, it is unclear if there is an association between the Social Vulnerability Index (SVI) and the intent of both fatal and nonfatal firearm injuries, and if these associations are modified by community race and ethnic composition. This study examines the association between community-level social vulnerability and firearm injury incidence in North Carolina (NC) using 2021-2022 emergency medical services (EMS) data.

Pre-operative stereotactic radiosurgery and peri-operative dexamethasone for resectable brain metastases: a two-arm pilot study evaluating clinical outcomes and immunological correlates.

Enhancing the efficacy of immunotherapy in brain metastases (BrM) requires an improved understanding of the immune composition of BrM and how this is affected by radiation and dexamethasone. Our two-arm pilot study (NCT04895592) allocated 26 patients with BrM to either low (Arm A) or high (Arm B) dose peri-operative dexamethasone followed by pre-operative stereotactic radiosurgery (pSRS) and resection (n= 13 per arm). The primary endpoint, a safety analysis at 4 months, was met.

American Radium Society Appropriate Use Criteria on Cardiac Toxicity Prevention and Management After Thoracic Radiotherapy.

Introduction: The multidisciplinary American Radium Society Thoracic Committee was assigned to create appropriate use criteria on cardiac toxicity prevention and management for patients undergoing radiotherapy.

Methods: A systematic review of the current literature was conducted. Case variants of patients with thoracic malignancies undergoing radiation were created based on presence or absence of cardiovascular risk factors and treatment-related risks assessed by dose exposure to the heart and cardiac substructures.

An Overview of Reviews on the Association of Low Calorie Sweetener Consumption With Body Weight and Adiposity.

Background: Numerous systematic reviews (SR) and meta-analyses (MA) on low calorie sweeteners (LCS) have been published in recent years, concluding that LCS have beneficial, neutral, or detrimental effects on various health outcomes, depending on the review.

Objectives: The objective of this overview of reviews was to determine how the methodologies of SR investigating the association between LCS consumption and body weight (BW) influence their findings and whether MA results can provide a consistent estimated effect.

Methods: Systematic searches of PubMed, Scopus, and Cochrane Library were conducted in November 2022 to identify SR of randomized controlled trials (RCT) or non-randomized studies (NRS) investigating the association between LCS consumption and BW.

A novel guided approach to radiofrequency ablation of thyroid nodules: the Toronto Sunnybrook experience.

Introduction: Thyroid nodules are extremely common being detected by ultrasonography in up to 67% of the population, with current surgical tenet maintaining that lobectomy is required for large symptomatic benign nodules or autonomously functionally nodules resulting in a risk of hypothyroidism or recurrent laryngeal nerve injury even in high volume centres. The introduction of radiofrequency ablation (RFA) has allowed thermal ablation of both benign and autonomously functioning thyroid nodules with minimal morbidity. The moving shot technique is the most well-established technique in performing RFA of thyroid nodules, and has proven to be safe, efficacious, accurate and successful amongst experienced clinicians.

Pilot of a text messaging system to monitor caregivers' and children's mental health recovery after pediatric traumatic injury.

Objective: Pediatric traumatic injury (PTI) is associated with a high risk for psychiatric sequelae. Most trauma centers do not adequately address the emotional needs of children and their caregivers. Technology-based programs offer a low-cost and low-burden opportunity to track and potentially enhance families' emotional recovery following PTI.

A multi-institutional feasibility lead-in trial of lymphatic mapping with SPECT-CT for evaluating contralateral disease in lateralized oropharynx cancer using 99m-technetium sulfur colloid.

Background: Lymphatic mapping with SPECT-CT has been demonstrated to accurately define lymphatic drainage patterns in oropharyngeal cancer but there has yet to be a study demonstrating its feasibility across multiple institutions.

Methods: Twelve adult patients with lateralized oropharyngeal carcinoma (T1-T3) who were planned for definitive or adjuvant radiotherapy without contralateral nodal disease underwent injection of 99-m technetium sulfur colloid followed by static planar lymphoscintigraphy to verify tracer migration, and SPECT-CT acquired at 30 ± 15 min (optional) and 3 h (±1 h) (mandatory time-point).

Results: All 12 patients completed the study with 7/12 patients having the injections performed under local anesthetic and 5 patients requiring general anesthetic.

Alien hand syndrome: An atypical presentation of acute left parietal stroke in a community emergency department.

A case of Alien hand syndrome as a presentation of an acute left parietal stroke to improve emergency providers recognition of the condition as a manifestation of acute stroke. We report a case of an 81-year-old female who presented with a complaint of inability to control her right arm accompanied with a subjective sense of right upper extremity numbness and weakness. It was later identified that the patient had an acute left parietal stroke and was describing alien hand syndrome, described as involuntary movements of the right hand and upper extremity.

Neoadjuvant and Adjuvant Treatments for Early Stage Resectable NSCLC: Consensus Recommendations From the International Association for the Study of Lung Cancer.

Advances in the multidisciplinary care of early stage resectable NSCLC (rNSCLC) are emerging at an unprecedented pace. Numerous phase 3 trials produced results that have transformed patient outcomes for the better, yet these findings also require important modifications to the patient treatment journey trajectory and reorganization of care pathways. Perhaps, most notably, the need for multispecialty collaboration for this patient population has never been greater.

Immune System Dose With Proton Versus Photon Radiotherapy for Treatment of Locally Advanced NSCLC.

Purpose: Emerging data have illuminated the impact of effective radiation dose to immune cells (EDIC) on outcomes in patients with locally advanced, unresectable non-small cell lung cancer (NSCLC) treated with intensity-modulated radiotherapy (IMRT). Hypothesizing that intensity-modulated proton therapy (IMPT) may reduce EDIC versus IMRT, we conducted a dosimetric analysis of patients treated at our institution.

Materials And Methods: Data were retrospectively collected for 12 patients with locally advanced, unresectable NSCLC diagnosed between 2019 and 2021 who had physician-approved IMRT and IMPT plans.

Current Research on Matching Trauma-Focused Therapies to Veterans: A Scoping Review.

Introduction: Trauma-focused (psycho)therapies (TFTs) are often used to treat post-traumatic stress disorder (PTSD) of (military) veterans, including prolonged exposure (PE), cognitive processing therapy (CPT), and eye movement desensitization and reprocessing. However, research thus far has not conclusively determined predictors of TFTs' success in this population. This scoping review's objectives are 1) to explore whether it is possible, based on currently available evidence, to match TFTs to veterans to maximize their outcomes, (2) to identify possible contraindications and adaptations of TFTs for this population, and (3) to identify gaps in the literature to guide future research.

Intensity-Modulated Reirradiation Therapy With Nivolumab in Recurrent or Second Primary Head and Neck Squamous Cell Carcinoma: A Nonrandomized Controlled Trial.

Importance: Intensity-modulated radiation therapy (IMRT) reirradiation of nonmetastatic recurrent or second primary head and neck squamous cell carcinoma (HNSCC) results in poor progression-free survival (PFS) and overall survival (OS).

Objective: To investigate the tolerability, PFS, OS, and patient-reported outcomes with nivolumab (approved standard of care for patients with HNSCC) during and after IMRT reirradiation.

Design, Setting, And Participants: In this multicenter nonrandomized phase 2 single-arm trial, the treatment outcomes of patients with recurrent or second primary HNSCC who satisfied recursive partitioning analysis class 1 and 2 definitions were evaluated.

Oropharyngeal Cancer Staging Health Record Extraction Using Artificial Intelligence.

Importance: Accurate, timely, and cost-effective methods for staging oropharyngeal cancers are crucial for patient prognosis and treatment decisions, but staging documentation is often inaccurate or incomplete. With the emergence of artificial intelligence in medicine, data abstraction may be associated with reduced costs but increased efficiency and accuracy of cancer staging.

Objective: To evaluate an algorithm using an artificial intelligence engine capable of extracting essential information from medical records of patients with oropharyngeal cancer and assigning tumor, nodal, and metastatic stages according to American Joint Committee on Cancer eighth edition guidelines.

Columnar Cell Thyroid Carcinoma: A Heterogeneous Entity Demonstrating Overlap Between Papillary Thyroid Carcinoma and Follicular Neoplasms.

Background: Columnar cell papillary thyroid carcinoma (CC-PTC) is a morphologic subtype of papillary thyroid carcinoma with a variable prognosis. It is characterized by neoplastic thyroid follicular-derived cells with pseudostratified columnar morphology arranged in papillary or follicular structures with supranuclear or subnuclear vacuoles. The molecular profile of this subtype has only recently come under scrutiny, with mixed results.
