AI Article Synopsis

  • Specialized ultrasound imaging modes can monitor and guide noninvasive and minimally-invasive thermal therapies.
  • One method utilizes two-dimensional imaging to track temperature changes during treatments like HIFU and RF ablation, validated through various tests.
  • The development of advanced imaging techniques enables real-time monitoring, enhancing the precision and effectiveness of thermal therapies with high spatial and temporal resolutions.

Article Abstract

We present specialized ultrasound imaging modes for monitoring and guidance of noninvasive and minimally-invasive thermal therapy. One mode is based on two-dimensional imaging of temperature change using diagnostic ultrasound. We have validated this method both in vivo and in vitro in monitoring the heating patterns produced by noninvasive HIFU source and minimally-invasive RF ablation device, respectively. In addition, a nonlinear method for imaging the quadratic echo components from HIFU-induced lesions has also been developed and tested in vivo. Illustrative results from both modes of imaging are presented. These results demonstrate the unique advantages of ultrasound as an image-guidance modality. Specifically, the high spatial and temporal resolutions that allow for imaging highly-localized short-duration therapeutic and sub-therapeutic HIFU beams. With the advent of highperformance computing hardware, these imaging modes are now implementable in real-time. This will lead to active realtime monitoring and control of a range of thermal therapies in the very near future.

The promises and perils of circulating tumor DNA for monitoring immunotherapy response in non-small cell lung cancer.

There has been a rapid expansion of immunotherapy options for non-small cell lung cancer (NSCLC) over the past two decades, particularly with the advent of immune checkpoint inhibitors. Despite the emerging role of immunotherapy in adjuvant and neoadjuvant settings though, relatively few patients will respond to immunotherapy which can be problematic due to expense and toxicity; thus, the development of biomarkers capable of predicting immunotherapeutic response is imperative. Due to the promise of a noninvasive, personalized approach capable of providing comprehensive, real-time monitoring of tumor heterogeneity and evolution, there has been wide interest in the concept of using circulating tumor DNA (ctDNA) to predict treatment response.

The rapid growth, invasiveness, and resistance to treatment of glioblastoma multiforme (GBM) underscore the urgent need for improved diagnostics and therapies. Current surgical practice is limited by challenges with intraoperative imaging, while recurrence monitoring requires expensive magnetic resonance or nuclear imaging scans. Here we introduce 'acoustic tumor paint', an approach to labeling brain tumors for ultrasound imaging, a widely accessible imaging modality.

Seizures are complex electrophysiological disturbances affecting one or more populations of brain neurons. Seizures following test article (TA) exposure pose significant challenges in drug development. This paper considers the diverse neurological manifestations, mechanisms, and functional and structural assessments needed to investigate TA-related seizure liabilities, with a particular focus on nonclinical species.

Aims: To assess outcomes of oral anti-hyperglycaemic therapies in people with diabetes secondary to a pancreatic condition (type 3c), where specific treatment guidance is limited.

Materials And Methods: Using hospital-linked UK primary care records (Clinical Practice Research Datalink; 2004-2020), we identified 7084 people with a pancreatic condition (acute pancreatitis, chronic pancreatitis, pancreatic cancer and haemochromatosis) preceding diabetes diagnosis (type 3c cohort), initiating oral glucose-lowering therapy (metformin, sulphonylureas, SGLT2-inhibitors, DPP4-inhibitors or thiazolidinediones), and without concurrent insulin treatment. We stratified by pancreatic exocrine insufficiency [PEI] (nā€‰=ā€‰5917 without PEI, 1167 with PEI) and matched to 97ā€‰227 type 2 diabetes (T2D) controls.

Importance: Preterm infants are recommended to receive most vaccinations at the same postnatal age as term infants. Studies have inconsistently observed an increased risk for postvaccination apnea in preterm infants.

Objective: To compare the proportions of hospitalized preterm infants with apnea and other adverse events in the 48 hours after 2-month vaccinations vs after no vaccinations.
