High and frequent expression of somatostatin receptors in differentiated neuroendocrine neoplasms has paved the way for receptor-based, targeted peptide receptor radionuclide therapy especially for nonoperable or metastatic disease. Besides tumors, radiation, in one form or another, has been tested to treat inflammatory disease as well, and this goes back to the early 1990s when the first case of pneumonia treated with radiation showed complete resolution. Currently, radiotracers help in not only in vivo inflammation detection, characterization, and staging but also, and more importantly, for selection of treatment in individual patients.

Background: While magnetic resonance imaging (MRI) remains the gold standard for morphological imaging, its ability to differentiate between tumor tissue and treatment-induced changes on the cellular level is insufficient. Notably, glioma cells, particularly glioblastoma multiforme (GBM), demonstrate overexpression of chemokine receptor-4 (CXCR4). This study aims to evaluate the feasibility of non-invasive Ga-Cixafor™ PET/CT as a tool to improve diagnostic accuracy in patients with high-grade glioma.

Ionizing radiotherapy (RT) is a widely used palliative and curative treatment strategy for malignancies. In solid tumors, RT-induced double strand breaks lead to the accumulation of indels, and their repair by non-homologous end-joining has been linked to the ID8 mutational signature in resistant cells. However, the extent of RT-induced DNA damage in hematologic malignancies and its impact on their evolution and interplay with commonly used chemotherapies has not yet been explored.

In newly diagnosed multiple myeloma (NDMM), measurable residual disease (MRD) status is prognostically important, but its role in treatment-decisions remains unclear. In a phase II trial (NCT04113018), we assessed daratumumab, carfilzomib, lenalidomide and dexamethasone (Dara-KRd) induction followed by a next generation sequencing (NGS) based MRD-adapted strategy. The primary endpoint was rate of complete response and stringent complete response (≥CR) after induction.

The hypothalamus plays an important role in aging, but it remains unclear regarding the underlying epigenetics and whether this hypothalamic basis can help address aging-related diseases. Here, by comparing mouse hypothalamus with two other limbic system components, we show that the hypothalamus is characterized by distinctively high-level DNA methylation during young age and by the distinct dynamics of DNA methylation and demethylation when approaching middle age. On the other hand, age-related DNA methylation in these limbic system components commonly and sensitively applies to genes in hypothalamic regulatory pathways, notably oxytocin (OXT) and gonadotropin-releasing hormone (GnRH) pathways.

Triple-negative breast cancer (TNBC) poses a significant clinical challenge due to its aggressive nature and limited therapeutic options. The interplay between DNA damage response (DDR) mechanisms and the emergence of neoantigens represents a promising avenue for developing targeted immunotherapeutic strategies and vaccines for TNBC. The DDR is a complex network of cellular mechanisms designed to maintain genomic integrity.

Article Synopsis
  • * Researchers analyzed the MMRF CoMMpass dataset and found that WEE1 expression levels can effectively distinguish between high-risk and low-risk patients, showing a significant difference in progression-free survival (PFS).
  • * The findings suggest that WEE1 expression is an independent prognostic factor for MM and may lead to new therapeutic strategies by exploring the causes of abnormal WEE1 expression.

Inguinal hernia repair is one of the most common surgical procedures performed worldwide. However, very few studies report data on the laparoscopic advantages of bilateral inguinal hernia (BIH) repair over the open approach. Therefore, this meta-analysis was conducted to compare the effectiveness of the laparoscopic trans-abdominal pre-peritoneal (TAPP) technique with the open Lichtenstein repair technique (OLR) for the repair of BIH.

Temporal region of the face is considered the most promising facial region for inducing panfacial effects, playing an increasingly important role in facial contouring and rejuvenation surgeries, which in turn has led to a rapid growth in the demand for aesthetic correction for temporal hollowing. In order to correct this issue and achieve a more youthful appearance, filler injections can be used. Although this procedure is generally safe and is increasingly popular, complications may happen.

In recent years, bioactive constituents from plants have been investigated as an alternative to synthetic approaches of therapeutics. Mangiferin (MGF) is a xanthone glycoside extracted from Mangifera indica and has shown numerous medicinal properties, such as antimicrobial, anti-diarrhoeal, antiviral, anti-inflammatory, antihypertensive, anti-tumours, and anti-diabetic effects. However, there are numerous challenges to its effective therapeutic usage, including its low water solubility, limited absorption, and poor bioavailability.

To comprehensively unravel the temporal relationship between initiating and driver events and its impact on clinical outcomes, we analyzed 421 whole-genome sequencing profiles from 382 patients. Using clock-like mutational signatures, we estimated a time lag of 2-4 decades between initiating events and diagnosis. In patients with hyperdiploidy, we demonstrate that trisomies of odd-numbered chromosomes can be acquired simultaneously with other chromosomal gains, such as 1q gain.
