Article Synopsis
  • - The study developed the LC-CVS OPSA, an assessment tool that focuses on safety in laparoscopic cholecystectomy surgery, to improve surgical training and align with the American Board of Surgery's initiatives.
  • - Expert surgeons rated ten surgical videos on a "safe" vs. "unsafe" scale, identifying 238 unsafe instances across various tasks and noting significant variations in ratings among the surgeons.
  • - Analysis of feedback revealed key reasons for unsafe ratings, such as failure to achieve the critical view of safety, suboptimal techniques, and potential future complications, leading to modifications in assessment instructions to enhance reliability.

Financial hardship in childhood cancer contributes to poor health outcomes and global disparities in survival, but the extent of the financial burden on families is not yet fully understood. We systematically reviewed financial hardship prevalence and individual components characterising financial hardship across six domains (medical, non-medical, and indirect costs, financial strategies, psychosocial responses, and behavioural responses) and compared characteristics across country income levels using an established theory of human needs. We included 123 studies with data spanning 47 countries.

Early and Late Toxicities of Chimeric Antigen Receptor T-Cells.

Hematol Oncol Clin North Am

December 2023

Pediatric Oncology Branch, Center for Cancer Research (CCR), National Cancer Institute (NCI), NIH, Building 10, Room 1W-3750, 9000 Rockville Pike MSC 1104, Bethesda, MD 20892, USA. Electronic address:

As chimeric antigen receptor (CAR) T-cell therapy is increasingly integrated into clinical practice across a range of malignancies, identifying and treating inflammatory toxicities will be vital to success. Early experiences with CD19-targeted CAR T-cell therapy identified cytokine release syndrome and neurotoxicity as key acute toxicities and led to unified initiatives to mitigate the influence of these complications. In this section, we provide an update on the current state of CAR T-cell-related toxicities, with an emphasis on emerging acute toxicities affecting additional organ systems and considerations for delayed toxicities and late effects.

Evaluating approaches for constructing polygenic risk scores for prostate cancer in men of African and European ancestry.

Am J Hum Genet

July 2023

Center for Genetic Epidemiology, Department of Population and Public Health Sciences, Keck School of Medicine, University of Southern California, Los Angeles, CA, USA.

Genome-wide polygenic risk scores (GW-PRSs) have been reported to have better predictive ability than PRSs based on genome-wide significance thresholds across numerous traits. We compared the predictive ability of several GW-PRS approaches to a recently developed PRS of 269 established prostate cancer-risk variants from multi-ancestry GWASs and fine-mapping studies (PRS). GW-PRS models were trained with a large and diverse prostate cancer GWAS of 107,247 cases and 127,006 controls that we previously used to develop the multi-ancestry PRS.

Evaluating Approaches for Constructing Polygenic Risk Scores for Prostate Cancer in Men of African and European Ancestry.

medRxiv

May 2023

Center for Genetic Epidemiology, Department of Population and Public Health Sciences, Keck School of Medicine, University of Southern California, Los Angeles, CA, USA.

Article Synopsis
  • Genome-wide polygenic risk scores (GW-PRS) were analyzed for their predictive ability regarding prostate cancer risk, compared to an established multi-ancestry polygenic risk score (PRS).
  • The GW-PRS models utilized data from a large and diverse group of nearly 235,000 participants, including individuals from both African and European ancestries.
  • Results showed that while GW-PRS had varying predictive abilities, the multi-ancestry PRS performed equally well or better in predicting prostate cancer risk for both ancestry groups, indicating GW-PRS may not offer significant improvements in risk prediction.

Purpose: Triple-negative invasive lobular carcinoma (TN-ILC) of breast cancer is a rare disease and the clinical outcomes and prognostic factors are not well-defined.

Methods: Women with stage I-III TN-ILC or triple-negative invasive ductal carcinoma (TN-IDC) of the breast undergoing mastectomy or breast-conserving surgery between 2010 and 2018 in the National Cancer Database were included. Kaplan-Meier curves and multivariate Cox proportional hazard regression were used to compare overall survival (OS) and evaluate prognostic factors.

The Ribbon Sign as a Radiological Indicator of Intramedullary Spinal Cord Subependymomas.

World Neurosurg

July 2023

Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, MD, USA; Department of Neurosurgery, Johns Hopkins Medicine, Institute for Brain Protection Sciences, Johns Hopkins All Children's Hospital, St. Petersburg, FL, USA. Electronic address:

Objective: Intramedullary spinal cord (IMSC) subependymomas are rare World Health Organization grade 1 ependymal tumors. The potential presence of functional neural tissue within the tumor and poorly demarcated planes presents a risk to resection. Anticipating a subependymoma on preoperative imaging can inform surgical decision-making and improve patient counseling.

Article Synopsis
  • The study used the Delphi method to establish a consensus among spine surgeons on anticoagulation and antiplatelet (AC/AP) medication management before and after elective spine surgery, as well as the initiation of venous thromboembolism (VTE) prophylaxis.
  • The consensus reached indicated that Direct Oral Anticoagulants should be stopped two days prior to surgery, while warfarin and other AC/AP medications should be halted five and seven days in advance, respectively.
  • Surgeons agreed on specific guidelines for restarting AC/AP medications and VTE prophylaxis based on patient risk factors, although there was no consensus on protocols for same-day staged surgeries.

Background: Adherence to antiretroviral treatment (ART) remains the cornerstone of optimal HIV outcomes, including viral suppression (VS), immune recovery, and decreased transmission risk. For many people with HIV (PWH), particularly those with early-acquired HIV, structural, behavioral, and cognitive barriers to adherence and competing priorities related to life events may be difficult to overcome, resulting in nonadherence. Long-acting injectable antiretroviral therapies (LAI-ART) may be a useful strategy to overcome some of these barriers.

Luspatercept is an approved therapy for selected patients with lower risk myelodysplasia requiring transfusion despite erythropoiesis-stimulating agents, based on the early results of a randomized trial against placebo. Zeidan and colleagues report that after a median of 26 months follow-up, 27% of patients commencing luspatercept were continuing therapy. Their updated analyses confirm that a significant minority (45%) of eligible patients can achieve transfusion independence, with a median durability of 30 weeks.

Background: We sought to define the association of the systemic immune inflammation index (SII) with prognosis and adjuvant therapy benefit among patients undergoing resection of extrahepatic cholangiocarcinoma (eCCA).

Methods: The impact of SII on overall (OS) and recurrence-free survival (RFS) following resection of eCCA was assessed and compared with other inflammatory markers and traditional prognostic factors. Propensity score matching (PSM) was used to determine the impact of adjuvant therapy (AT) on OS and RFS relative to low versus high SII.
