Ultrasound-guided percutaneous microwave ablation versus surgery for papillary thyroid microcarcinoma.
Authors: Li J, Liu Y, Liu J, Qian L
Abstract
BACKGROUND: Papillary thyroid microcarcinoma (PTMC) has high incidence and low disease-specific mortality. However, active surveillance is not accepted by most patients owing to high physical or psychological pressures. The emergence of ablation technologies is supplanting traditional surgery. Our goal was to compare the clinical outcomes of microwave ablation (MWA) and surgery for T1aN0M0 PTMC.
METHODS: A total of 92 consecutive patients with T1aN0M0 PTMC were studied retrospectively. Forty-six patients had been treated with MWA, and the other 46 had undergone surge...

Temperature-sensitive liposomal ciprofloxacin for the treatment of biofilm on infected metal implants using alternating magnetic fields.
In this study, we treated a metal prosthesis infection model using a combination of ciprofloxacin-loaded temperature-sensitive liposomes (TSL) and alternating magnetic fields (AMF). AMF heating is used to disrupt the biofilm and release the ciprofloxacin-loaded TSL. The three main objectives of this study were to (1) investigate low- and high-temperature-sensitive liposomes (LTSLs and HTSLs) containing the antimicrobial agent ciprofloxacin for temperature-mediated antibiotic release, (2) characterise in vitro ciprofloxacin release and stability and (3) study the efficacy of combining liposomal ciprofloxacin with AMF agains...

An overview of the role of sympathetic regulation of immune responses in infectious disease and autoimmunity.
Authors: Bucsek MJ, Giridharan T, MacDonald CR, Hylander BL, Repasky EA
Abstract
Stress in patients and pre-clinical research animals plays a critical role in disease progression Activation of the sympathetic nervous system (SNS) by stress results in secretion of the catecholamines epinephrine (Epi) and norepinephrine (NE) from the adrenal gland and sympathetic nerve endings. Adrenergic receptors for catecholamines are present on immune cells and their activity is affected by stress and the accompanying changes in levels of these neurotransmitters. In this short review, we discuss how this adrenergic stress impacts...

Heat transfer from nanoparticles for targeted destruction of infectious organisms.
Authors: Cortie MB, Cortie DL, Timchenko V
Abstract
Whereas the application of optically or magnetically heated nanoparticles to destroy tumours is now well established, the extension of this concept to target pathogens has barely begun. Here we examine the challenge of targeting pathogens by this means and, in particular, explore the issues of power density and heat transfer. Depending on the rate of heating, either hyperthermia or thermoablation may occur. This division of the field is fundamental and implies very different sources of excitation and heat transfer for the two modes, and different strategies for th...

Thermal shock susceptibility and regrowth of Pseudomonas aeruginosa biofilms.
Authors: Ricker EB, Aljaafari HAS, Bader TM, Hundley BS, Nuxoll E
Abstract
Biofilms on implanted medical devices cause thousands of patients each year to undergo multiple surgeries to remove and replace the implant, driving billions of dollars in increased health care costs due to the lack of viable treatment options for in situ biofilm eradication. Remotely activated localised heating is under investigation to mitigate these biofilms; however, little is known about the temperatures required to kill the biofilms. To better understand the required parameters this study investigated the thermal susceptibility of biof...

Progress on utilizing hyperthermia for mitigating bacterial infections.
Authors: Ibelli T, Templeton S, Levi-Polyachenko N
Abstract
Recovery from systemic or local bacterial infections can be lengthy and costly, with the clinical challenges being further complicated when bacteria acquire resistance to current antibiotics. Hyperthermia offers new mechanisms for removing bacteria via ablation, or sensitising them to chemical agents. The first part of this review provides a background on the bacterial biofilms, their response to hyperthermia, and acquired resistance to antibiotics, followed by the clinical challenges they present in managing infections associated with soft tissues and bio...

Abstract
A recent study by Ooi and Ooi (EH Ooi, ET Ooi, Mass transport in biological tissues: Comparisons between single- and dual-porosity models in the context of saline-infused radiofrequency ablation, Applied Mathematical Modelling, 2017, 41, 271-284) has shown that single-porosity (SP) models for describing fluid transport in biological tissues significantly underestimate the fluid penetration depth when compared to dual-porosity (DP) models. This has raised some concerns on whether the SP model, when coupled with models of radiofreque...

Abstract
Antimicrobial chemotherapy and surgery are classical methods for treating infectious diseases. However, there is a need for alternative methods to cure infections caused by antibiotic-resistant pathogens, recurrent or chronic infections, and unreachable local infections in which the use of drugs or surgery is anatomically and physically restricted. Several microorganisms are known to be sensitive to mild hyperthermia, and this sensitivity is one of the potential benefits proposed for the host during an episode of fever. Additionally, some immunological or biophysical changes occ...

Abstract
Hyperthermia therapy (HT) is the exposure of a region of the body to elevated temperatures to achieve a therapeutic effect. HT anticancer properties and its potential as a cancer treatment have been studied for decades. Techniques used to achieve a localized hyperthermic effect include radiofrequency, ultrasound, microwave, laser, and magnetic nanoparticles (MNPs). The use of MNPs for therapeutic hyperthermia generation is known as magnetic hyperthermia therapy (MHT) and was first attempted as a cancer therapy in 1957. However, despite more re...

Abstract
PURPOSE: The aim of this study was to evaluate the effect of preoperative pregabalin on postoperative analgesia in patients undergoing radiofrequency ablation (RFA) of hepatic focal lesions (HFLs).
METHODS: This randomized controlled study was carried out on 70 adult patients for whom RFA was indicated to treat hepatocellular carcinoma. They were randomized into two groups: Group I: 35 patients who were given a placebo before the procedure and Group II: 35 patients who were given 150 mg of oral pregabalin one hour be...

Percutaneous radiofrequency ablation of painful spinal metastasis: a systematic literature assessment of analgesia and safety.
CONCLUSION: RFA, combined with vertebral augmentation in most of the cases, is effective and safe in achieving short to mid-term (from 1 week to 6 months) analgesia in patients affected by painful spinal metastasis.

Real-time estimation of lesion depth and control of radiofrequency ablation within ex vivo animal tissues using a neural network.
CONCLUSIONS: The results show that a NN could make lesion depth estimations in real-time using less in situ devices than current techniques. With the NN-based technique, physicians could deliver quicker and more precise ablation therapy.
