Background: Laser interstitial thermal therapy (LITT) is a minimally invasive surgical treatment being employed frequently for radiographically progressive brain metastases. Considerable interest exists in combining LITT-mediated in situ vaccination to license immune checkpoint blockade (ICB). No studies have examined the clinical feasibility of this combination in brain metastases.

Purpose: There is an unmet need for new treatments for many central nervous system tumors. An expanding body of research supports the use of laser interstitial thermal therapy (LITT) in the treatment of gliomas, recurrent brain metastases, and radiation necrosis.

Methods: In this review, we highlight emerging indications for LITT, including its use adjacent to eloquent structures, in the posterior fossa, and for meningioma and tumors of the vertebral column.

Article Synopsis
  • The study aimed to determine if selecting oral antiplatelet drugs based on a patient's genotype using a clinical decision support algorithm can lower the rate of major adverse cardiovascular and cerebrovascular events among Caribbean Hispanic patients following treatment.
  • Conducted as an open-label, multicenter, non-randomized trial across eight hospitals in Puerto Rico, it involved 300 patients who received percutaneous coronary intervention and were divided into standard-of-care and genotype-guided groups.
  • Results indicated that although the genotype-guided group had a lower risk of major adverse events compared to the standard group (8.7% vs 10.7%), the difference was not statistically significant.

A 66-year-old female with end-stage renal disease and heart failure with reduced ejection fraction, status post implantable cardioverter defibrillator (ICD) presented to the emergency department with dizziness and fatigue. An electrocardiogram showed sinus rhythm, complete atrioventricular block, and ventricular paced rhythm at 30 beats per minute (bpm). Device interrogation revealed a programmed VVI mode with a lower rate limit of 40 bpm and evidence of T wave oversensing.

Dengue fever has remained a continuing global medical threat that impacts half of the world's population. Developing a highly effective dengue vaccine, with live-attenuated tetravalent vaccines as leading candidates, remains essential in preventing this disease. For the development of live virus vaccines (LVVs), potency measurements play a vital role in quantifying the active components of vaccine drug substance as well as drug product during various stages of research, development, and post-licensure evaluations.

Article Synopsis
  • Laser interstitial thermal therapy (LITT) is an innovative treatment for intracranial tumors and radiation necrosis allowing for tissue diagnosis and quick resumption of chemotherapy, but it causes post-treatment edema that complicates recovery assessment.* -
  • A study was conducted from 2015 to 2023 with 61 patients using automated image analysis to quantify changes in lesion volumes following LITT, showing a significant initial increase in contrast-enhancing lesion volume that typically returned to baseline within 6 months.* -
  • Results indicated that 37.5% of patients experienced volumetric progression post-treatment, which correlated with significantly lower overall survival rates, highlighting the need for standardized response assessment criteria in clinical settings.*

Background: After percutaneous coronary intervention (PCI), clopidogrel resistant patients are at an increased risk of major adverse cardiovascular and cerebrovascular events (MACCEs). We aimed to assess whether genotype-guided selection of oral antiplatelet drugs using a clinical decision support (CDS) algorithm reduces the occurrence of these ischemic events and improves outcomes among Caribbean Hispanic patients from Puerto Rico, who are underrepresented in clinical pharmacogenomic (PGx)-guided implementation studies.

Methods: Individual platelet function testing (PRU) measures, *2 and rs662 genotypes, clinical and demographic data from 8 medical facilities were included.

The instrumental role of CK2 in the SARS-CoV-2 infection has pointed out this protein kinase as promising therapeutic target in COVID-19. Anti-SARS-CoV-2 activity has been reported by CK2 inhibitors ; however, no anti-CK2 clinical approach has been investigated in COVID-19. This trial aimed to explore the safety and putative clinical benefit of CIGB-325, an anti-CK2 peptide previously assessed in cancer patients.

Objective: To develop an antimicrobial and anti-adherent thymol (TOH)-containing coating on titanium (Ti) by a bioinspired one-step biocompatible method.

Methods: A nanolayer of adsorbed TOH (TOH-NL-Ti) was formed by an easy deep coating method on Ti surface. The treatment consists in a simple one-step immersion process in a TOH-containing solution.

Introduction: Minority populations in the USA are disproportionately affected by cardiovascular conditions. Reduced responsiveness to clopidogrel among carriers of variants has been reported in patients with either coronary artery disease (CAD) or acute coronary syndrome (ACS) after the percutaneous coronary intervention (PCI). Previous studies have evaluated genotyping-guided antiplatelet therapy in selected populations; however, this has yet to be tested among Hispanics.

Since surface plays a key role in bioactivity, the response of the host to the biomaterial will determine the success or failure of the prosthesis. The purpose of this study is to make an exhaustive analysis of the histological and histochemical characteristics of new bone tissue around Zr implants anodized at 60 V (Zr60) supported by histomorphometric methods in a rat model. Fibrous tissue was observed around the control implants (Zr0) and osteoblasts were identified on the trabeculae close to the implantation site that showed typical cytological characteristics of active secretory cells, regardless of the surface condition.

Anxiety is known to dysregulate the salience, default mode, and central executive networks of the human brain, yet this phenomenon has not been fully explored across the STEM learning experience, where anxiety can impact negatively academic performance. Here, we evaluated anxiety and large-scale brain connectivity in 101 undergraduate physics students. We found sex differences in STEM-related and clinical anxiety, with longitudinal increases in science anxiety observed for both female and male students.

For two decades, 25% of the veterans who served in the 1991 Gulf War (GW) have been living with Gulf War Illness (GWI), a chronic multisymptom illness. Evidence suggests that brain structures involved in cognitive function may be affected in GWI. Gulf War agents such as the acetylcholinesterase (AChE) inhibitor pyridostigmine bromide (PB) and the pesticide permethrin (PER) are considered key etiogenic factors in GWI.

States are increasingly considering legislative and regulatory avenues to establish the role of radiologist assistants (RAs) under current state medical practice acts or state radiation control regulatory programs. It is critical that radiology practices be cautious to comply with federal and state laws and regulations to ensure that these advanced practice professionals provide the appropriate services under the appropriate level of supervision. For quality-of-care reasons, the ACR remains concerned about the scope of practice of radiology practitioner assistants and some misinformation that has spread to state officials about the assistants' role in radiology practice.
