Deep brain stimulation is an efficacious treatment for dystonia. While the internal pallidum serves as the primary target, recently, stimulation of the subthalamic nucleus (STN) has been investigated. However, optimal targeting within this structure and its surroundings have not been studied in depth.

Article Synopsis
  • Ventricular arrhythmias (VAs) like ventricular tachycardia and ventricular fibrillation pose serious treatment challenges with high risks of morbidity and mortality, particularly in patients unresponsive to standard therapies.
  • This study examined the safety and effectiveness of CT-guided left stellate ganglion cryoneurolysis (SGC) in these refractory VA patients across two hospitals, involving 17 patients with a notable reduction in defibrillation events after the procedure.
  • Results showed that 82% of patients were free from defibrillation 24 hours post-procedure, with no serious adverse effects reported, highlighting the potential of SGC as a beneficial alternative treatment strategy for refractory VAs.

  • * Researchers identified 21 human ITPR1 GOF variants and created a mouse model with one of these variants (ITPR1-W1457G), which was found to be prone to stress-induced ventricular arrhythmias.
  • * Both mouse models and human data suggest that ITPR1 GOF variants increase Ca handling abnormalities and arrhythmia risk, with 7 rare ITPR1 variants in a human database showing similar GOF behavior linked to cardiac

Article Synopsis
  • A comprehensive overview of Cochrane reviews was conducted to assess the effectiveness of various smoking cessation interventions, revealing diverse outcomes across studies.
  • The analysis included 71 reviews and 3022 trials, highlighting pharmacotherapy as a more reliable method for promoting long-term abstinence compared to non-pharmacological therapies, which showed considerable variability in effectiveness.
  • Overall, the methodological quality of the reviews was good, but further research is needed to better understand and integrate non-pharmacological interventions in smoking cessation efforts.

Needle-based injections currently enable the administration of a wide range of biomacromolecule therapies across the body, including the gastrointestinal tract, through recent developments in ingestible robotic devices. However, needles generally require training, sharps management and disposal, and pose challenges for autonomous ingestible systems. Here, inspired by the jetting systems of cephalopods, we have developed and evaluated microjet delivery systems that can deliver jets in axial and radial directions into tissue, making them suitable for tubular and globular segments of the gastrointestinal tract.

Introduction: Though recognized as a potential cause of autosomal dominant Alzheimer's disease, the pathogenicity of many PSEN2 variants remains uncertain. We compared amyloid beta (Aβ) production across all missense PSEN2 variants in the AlzForum database and, when possible, to corresponding PSEN1 variants.

Methods: We expressed 74 PSEN2 variants, 21 of which had known, homologous PSEN1 pathogenic variants with the same amino acid substitution, in HEK293 cells lacking presenilin 1/2.

Extrachromosomal DNA (ecDNA) presents a major challenge for cancer patients. ecDNA renders tumours treatment resistant by facilitating massive oncogene transcription and rapid genome evolution, contributing to poor patient survival. At present, there are no ecDNA-specific treatments.

CDK4/6 inhibition in combination with endocrine therapy is the standard of care for estrogen receptor (ER+) breast cancer, and although cytostasis is frequently observed, new treatment strategies that enhance efficacy are required. Here, we perform two independent genome-wide CRISPR screens to identify genetic determinants of CDK4/6 and endocrine therapy sensitivity. Genes involved in oxidative stress and ferroptosis modulate sensitivity, with GPX4 as the top sensitiser in both screens.

Article Synopsis
  • Intraoperation hypotension (IOH) during surgery can have negative effects, leading to the routine use of norepinephrine (NE) to manage blood pressure under general anesthesia, although its pharmacokinetics during such conditions are not well understood.
  • The study aimed to analyze the pharmacokinetics of NE in healthy volunteers in both awake and general anesthesia states, using a step-up dosing method and measuring plasma concentrations.
  • Results indicated that a two-compartment model effectively described NE dynamics, finding that general anesthesia reduced NE clearance by 10%, with weight, age, and session (awake vs. anesthesia) being significant factors affecting its clearance.

In the commercial swine farm setting, the postweaning period is a critical window during which piglets are highly susceptible to infection and enterotoxigenic E. coli (ETEC)-associated diarrhea. Short-chain fatty acids and their glycerides are compounds that may influence intestinal health; however, valerate is one that has not been well-characterized for its role as a dietary supplement.

Background: Osteochondral allograft transplantation (OCAT) has become a standard-of-care treatment option for patients with large symptomatic articular defects. Recent advances in allograft science and OCAT protocols have been reported to result in consistently robust outcomes after OCAT in the knee. However, only short-term comparisons have been reported, and analyses are lacking for treatment failure risk factors that account for confounding variables.

  • Brentuximab vedotin has been shown to improve outcomes in treating advanced classic Hodgkin's lymphoma, but it also causes more toxic side effects in adults, while many pediatric patients still need radiation therapy and face challenges with relapse.
  • A phase 3 trial involving patients aged 12 and older tested two treatment combinations: brentuximab vedotin with standard chemotherapy (BV+AVD) versus nivolumab with standard chemotherapy (N+AVD), aiming to assess progression-free survival.
  • Results indicated that N+AVD significantly enhances progression-free survival compared to BV+AVD, with a 2-year survival rate of 92% for N+AVD versus 83% for BV

Article Synopsis
  • Pulmonary hypertension (PH) is a severe disease linked to damage in blood vessels of the lungs and involves the degradation of important proteins, such as BMPR2, by the enzyme cathepsin L, leading to cell death through a process called pyroptosis.
  • Research showed that cathepsin L levels are significantly higher in patients with pulmonary arterial hypertension, and its inhibition in animal models of PH improved conditions related to the disease, including reduced pressure in the heart and enhanced blood vessel health.
  • The study concludes that cathepsin L contributes to the progression of PH by degrading BMPR2, which triggers a cascade leading to programmed cell death in endothelial cells, highlighting a potential therapeutic target for treating PH.

Article Synopsis
  • An error grid is a tool that helps compare glucose levels measured by devices to see if they are correct and to identify any risks.
  • Experts created a new error grid called the DTS Error Grid that works for both blood glucose monitors (BGMs) and continuous glucose monitors (CGMs), organizing accuracy into five risk zones.
  • The results showed that the DTS Error Grid provides a clearer picture of how accurate these devices are and includes a separate matrix to evaluate how well CGMs track glucose trends over time.

Purpose: Patients with HER2-positive breast cancer brain metastases have few effective systemic therapy options. In a prior study, pertuzumab with high-dose trastuzumab demonstrated a high clinical benefit rate (CBR) in the central nervous system (CNS) in patients with brain metastases. The current trial evaluated whether the addition of atezolizumab to this regimen would produce further improvements in CNS response.

Resistance to PD-1 blockade in onco-immunotherapy greatly limits its clinical application. T cell immunoglobulin and mucin domain containing-3 (Tim-3), a promising immune checkpoint target, is cleaved by ADAM10/17 to produce its soluble form (sTim-3) in humans, potentially becoming involved in anti-PD-1 resistance. Herein, serum sTim-3 upregulation was observed in non-small cell lung cancer (NSCLC) and various digestive tumors.
