Purpose: To present our results in a series of 35 patients with malignant pulmonary lesions, who underwent radiofrequency thermal ablation (RFA) during a period of 18 months.
Materials And Methods: In our institution, 55 RFA sessions under computed tomography (CT) guidance were performed on 48 pulmonary malignant lesions (23 inoperable primary and 25 metastatic) in 35 patients.
Results: Total necrosis was noted in 19 primary (82.6%) and in 19 metastatic lesions (76%). In four primary (17.4%) and in six metastatic lesions (14%), partial necrosis was achieved, and a second RFA session was performed. The 6-month spiral CT follow-up demonstrated recurrence in seven lesions (14.5%) (four primary and three metastatic), which were treated with an additional RFA session. Two of the patients who underwent the procedure died of disseminated disease after one year, accounting for a 1-year survival rate of 94.2%. Mean survival was 14.48 +/- 3.3 months.
Conclusion: RFA is an effective method for treating unresectable lung carcinoma and lung metastases.

Radiofrequency ablation (RFA), as a minimally invasive surgery strategy based on local thermal-killing effect, is widely used in the clinical treatment of multiple solid tumors. Nevertheless, RFA cannot achieve the complete elimination of tumor lesions with larger burden or proximity to blood vessels. Incomplete RFA (iRFA) has even been validated to promote residual tumor growth due to the suppressive tumor immune microenvironment (TIME).

Background Interest in microwave ablation (MWA) and radiofrequency ablation (RFA) use for treating secondary hyperparathyroidism (SHPT) is rising; however, ablation outcomes in patients with SHPT are not well characterized. Purpose To assess the response of parathyroid hormone (PTH), calcium, phosphorus, and alkaline phosphatase (ALP) levels to US-guided parathyroid MWA and RFA and the safety of these treatments in participants with SHPT. Materials and Methods This prospective multicenter cohort study, conducted from September 2017 to March 2022, included participants with SHPT.

Aluminum nitride (AlN) with a wide band gap (approximately 6.2 eV) has attractive characteristics, including high thermal conductivity, a high dielectric constant, and good insulating properties, which are suitable for the field of resistive random access memory. AlN thin films were deposited on ITO substrate using the radio-frequency magnetron sputtering technique.

The standard of care for early-stage NSCLC has historically been surgical resection. Given the association of lung cancer with smoking, a large number of early-stage patients also have active smoking-related medical comorbidities such as COPD precluding surgery. The current approach for treating such inoperable patients is frequently considered to be stereotactic body radiation therapy (SBRT).

Atrial fibrillation (AF) is the leading cause of arrhythmia-related morbidity and mortality. Recurrent symptoms, hospitalizations, and cost burden to patients have necessitated treatments beyond antiarrhythmic drugs (AADs) for patients with AF. Catheter ablation has proven to be effective over medical therapy alone; however the recurrence rates for atrial tachyarrhythmias post-ablation remain significant, particularly in patients with persistent and long-standing persistent AF.
