Pelvic insufficiency fractures in locally advanced cervical cancer: the diagnostic yield of post-treatment MRI in a tertiary centre.

Purpose: To assess the incidence of pelvic insufficiency fractures (PIFs) after concurrent chemoradiotherapy (CCRT) in patients with locally advanced cervical cancer (LACC), their time of onset and risk factors. We also analysed the inter-observer agreement between gynaecologic radiologists (GYN readers) and radiologists expert in musculoskeletal imaging (MSK reader) in detecting PIFs in our tertiary care centre.

Methods: Patients with confirmed LACC who underwent concurrent chemoradiation (CCRT) at our institution from June 2019 to November 2022 were retrospectively included.

Exploring radiomic features of lateral cerebral ventricles in postmortem CT for postmortem interval estimation.

The aim of this study is to investigate the potential of radiomic features extracted from postmortem computed tomography (PMCT) scans of the lateral cerebral ventricles (LCVs) to provide information on the time since death, or postmortem interval (PMI), a critical aspect of forensic medicine. Periodic PMCT scans, referred to as "sequential scans", were obtained from twelve corpses with known times of death, ranging from 5.5 to 273 h postmortem.

Response prediction for neoadjuvant treatment in locally advanced rectal cancer patients-improvement in decision-making: A systematic review.

Background: Predicting pathological complete response (pCR) from pre or post-treatment features could be significant in improving the process of making clinical decisions and providing a more personalized treatment approach for better treatment outcomes. However, the lack of external validation of predictive models, missing in several published articles, is a major issue that can potentially limit the reliability and applicability of predictive models in clinical settings. Therefore, this systematic review described different externally validated methods of predicting response to neoadjuvant chemoradiotherapy (nCRT) in locally advanced rectal cancer (LARC) patients and how they could improve clinical decision-making.

A transgene with enhanced therapeutic potential for the preclinical development of gene therapy to treat mucopolysaccharidosis type IVB.

Mucopolysaccharidosis type IVB (MPSIVB) is a lysosomal storage disorder caused by β-galactosidase (β-GAL) deficiency characterized by severe skeletal and neurological alterations without approved treatments. To develop hematopoietic stem progenitor cell (HSPC) gene therapy (GT) for MPSIVB, we designed lentiviral vectors (LVs) encoding human β-GAL to achieve supraphysiological release of the therapeutic enzyme in human HSPCs and metabolic correction of diseased cells. Transduced HSPCs displayed proper colony formation, proliferation, and differentiation capacity, but their progeny failed to release the enzyme at supraphysiological levels.

Transcriptomic analysis of BM-MSCs identified EGR1 as a transcription factor to fully exploit their therapeutic potential.

Bone marrow-mesenchymal stromal cells (BM-MSCs) are key components of the BM niche, where they regulate hematopoietic stem progenitor cell (HSPC) homeostasis by direct contact and secreting soluble factors. BM-MSCs also protect the BM niche from excessive inflammation by releasing anti-inflammatory factors and modulating immune cell activity. Thanks to these properties, BM-MSCs were successfully employed in pre-clinical HSPC transplantation models, increasing the rate of HSPC engraftment, accelerating the hematological reconstitution, and reducing the risk of graft failure.

Worsening trends in the frequency of methamphetamine and other stimulant use between treatment admission and discharge.

Background: Treatment for methamphetamine and other stimulants can be effective but treatment attrition and continued use are very high. Abstinence is the conventional outcome used to evaluate treatment success, but defining treatment success in this way misses opportunities to promote improved health even when abstinence is not achieved. Reducing methamphetamine and stimulant use without abstinence is associated with many positive outcomes.
