New technologies for future of surgery in Ireland: An RCSI working Group report 2024.

Introduction: Surgery is a cognitive discipline whose practitioners characteristically use technology during operations for patients. With accelerating technological innovation throughout society and healthcare, we sought to develop a shared position for Irish surgery via a commissioned work programme by the Royal College of Surgeons in Ireland.

Methods: Using Stanford design principles, representative clinical specialty and academic leads and higher trainee representatives across 15 specialties were surveyed regarding sentiments, perspectives and concerns regarding now and near future technology in clinical practice, career considerations and training/education.

Venous disease progression in western Europe (VENPRO): A prospective cohort study.

A prospective cohort study aimed to determine factors which influence the progression of chronic venous disease (CVD) in an attempt to aid in the early identification of those at patients who are likely to benefit from early intervention. A prospective cohort study of patients referred to tertiary vascular services with varicose veins over 7 years was conducted. The primary outcome measure was the rate of disease progression from time of referral to time of consultation.

Proposed framework regarding management of patients with breast cancer and anti-cancer treatment-related elevation in cardiac troponin.

Cardiac biomarkers are a vital component within the first edition of the European Society of Cardiology guidelines in Cardio-Oncology. Specifically, they are mentioned in the definition of mild asymptomatic cancer therapy-related cardiac dysfunction, where left ventricular systolic function is ≥50 % with two outcomes; either a new decrease in global longitudinal strain >15 % from baseline and/or a new rise in cardiac biomarkers above the defined 99th percentile cut off values. Cardiac troponin is one such biomarker.

"Veins first" versus "artery first" approach for management of mixed arterial venous leg ulcers (MAVLU): Systematic review and meta-analysis.

Introduction: Mixed Arterial and Venous Leg Ulcers (MAVLU) are challenging. The optimal intervention sequence (artery-first vs vein first) is unclear. This review evaluates current evidence on surgical intervention sequencing.

Dielectric characterisation of human adrenal glands and adrenal tumours for the development of microwave ablation technologies for hypertension treatment.

Adrenal gland-induced hypertension results from underlying adrenal gland disorders including Conn's syndrome, Cushing's syndrome, and Pheochromocytoma. These adrenal disorders are a risk for cardiovascular and renal morbidity and mortality. Clinically, treatment for adrenal gland-induced hypertension involves a pharmaceutical or surgical approach.

Evaluating Surgical Outcomes Between Estrogen Receptor Positive Invasive Lobular and Invasive Ductal Carcinoma of the Breast-A Propensity Matched Analysis.

Introduction: Invasive lobular carcinoma (ILC) contributes significantly to the global cancer burden and is the most common of the histological "special types" of breast cancer. ILC has unique features setting it apart from the more common invasive ductal carcinoma (IDC). Despite differences, treatment algorithms do not consider histological differences.

Understanding cardiac events in breast cancer (UCARE): pilot cardio-oncology assessment and surveillance pathway for breast cancer patients.

Purpose: In Ireland, over 3000 patients are diagnosed with breast cancer annually, and 1 in 9 Irish women will be diagnosed with breast cancer in their lifetime. There is evidence that female breast cancer survivors are more likely to die of cardiovascular disease than their age-matched counterparts. Specific services for cancer patients suffering from cancer therapy related cardiovascular toxicity have led to a higher incidence of safe anti-cancer treatment completion.

Risk Prediction, Diagnosis and Management of a Breast Cancer Patient with Treatment-Related Cardiovascular Toxicity: An Essential Overview.

Breast cancer is amongst the most common invasive cancers in adults. There are established relationships between anti-cancer treatments for breast cancer and cardiovascular side effects. In recent years, novel anti-cancer treatments have been established, as well as the availability of multi-modal cardiac imaging and the sophistication of treatment for cardiac disease.

Pharmacological Thromboprophylaxis for VTE Post-Endovenous Ablation of Varicose Veins: Network Meta-Analysis.

Objective: Endovenous ablation has revolutionized treatment of varicose vein surgery but is associated with a risk of venous thromboembolism. There is no consensus regarding anticoagulation protocols for these patients. This network meta-analysis (NMA) aims to identify which anticoagulant is optimal in this cohort for clot prevention with minimal risk of adverse bleeding events.

Histology-validated electromagnetic characterization of ex-vivo ovine lung tissue for microwave-based medical applications.

Microwave thermal ablation is an established therapeutic technique for treating malignant tissue in various organs. Its success greatly depends on the knowledge of dielectric properties of the targeted tissue and on how they change during the treatment. Innovation in lung navigation has recently increased the clinical interest in the transbronchial microwave ablation treatment of lung cancer.

Collagen-I influences the post-translational regulation, binding partners and role of Annexin A2 in breast cancer progression.

Introduction: The extracellular matrix (ECM) has been heavily implicated in the development and progression of cancer. We have previously shown that Annexin A2 is integral in the migration and invasion of breast cancer cells and in the clinical progression of ER-negative breast cancer, processes which are highly influenced by the surrounding tumor microenvironment and ECM.

Methods: We investigated how modulations of the ECM may affect the role of Annexin A2 in MDA-MB-231 breast cancer cells using western blotting, immunofluorescent confocal microscopy and immuno-precipitation mass spectrometry techniques.

Multimodal Imaging of Cancer Therapy-Related Cardiac Dysfunction in Breast Cancer-A State-of-the-Art Review.

Background: This review focuses on multimodality imaging of cardiotoxicity in cancer patients, with the aim of evaluating the effectiveness of different techniques in detecting and monitoring cardiac changes associated with cancer therapy.

Methods: Eight studies were included in the review, covering various imaging modalities such as cardiac magnetic resonance imaging, echocardiography, and multigated acquisition scanning.

Results: Cardiac magnetic resonance imaging emerged as the most definitive modality, offering real-time detection, comprehensive assessment of cardiac function, the ability to detect early myocardial changes, and superior detection of cardiotoxicity when compared to the other imaging modalities.

Association of clinical biomarkers and response to neoadjuvant therapy in breast cancer.

Introduction: Neoadjuvant therapy is an essential component of multimodality therapy for locally advanced breast adenocarcinoma (BC). Complete pathologic response (pCR) is a useful surrogate for long-term oncologic outcome.

Aim: To assess the association between clinicopathologic, molecular and immunological markers and treatment response to neoadjuvant therapy in BC.

Circulating microRNAs can predict chemotherapy-induced toxicities in patients being treated for primary breast cancer.

Purpose: Prescribing NAC for breast cancer is a pragmatic treatment strategy for several reasons; however, certain patients suffer chemotherapy-induced toxicities. Unfortunately, identifying patients at risk of toxicity often proves challenging. MiRNAs are small non-coding RNA molecules which modulate genetic expression.
