Biopsy-Proven T-Cell Mediated Rejection After Belatacept Rescue Conversion: A Multicenter Retrospective Study.

After kidney transplantation, conversion to belatacept is a promising alternative in patients with poor graft function or intolerance to calcineurin inhibitors. The risk of acute rejection has not been well described under these conditions. Here we present a retrospective multicenter study investigating the occurrence of acute rejection after conversion in 901 patients (2011-2021).

Evolution in Documented Goals of Care at End of Life for Adolescents and Younger Adults With Cancer.

Importance: Little is known about the nature of change in goals of care (GOC) over time among adolescents and younger adult (AYA) patients aged 12 to 39 years with cancer near the end of life. Understanding how GOC evolve may guide clinicians in supporting AYA patients in making end-of-life decisions.

Objective: To assess frequency, timing, and evolution of documented GOC among AYA patients with cancer in the last 90 days of life.

Physical activity and incident cardiovascular disease in breast cancer survivors: the pathways study.

Purpose: Breast cancer survivors experience higher rates of cardiovascular disease (CVD) than women without breast cancer, due in part to cardiotoxic cancer treatments and shared lifestyle risk factors. Physical activity is associated with lower mortality risk in breast cancer survivors, but associations with CVD have not been examined in detail.

Methods: The Pathways Study is a prospective cohort study of 4,504 women diagnosed with invasive breast cancer between 2005 and 2013.

Men who have sex with men perceiving that sex with women carries the greatest risk of HIV acquisition: results from a mixed-methods systematic review in sub-Saharan Africa.

Introduction: In sub-Saharan Africa (SSA), men who have sex with men (MSM) often have female sexual partners. Their overall risk of acquiring HIV is higher with male partners. Risk perception is associated with HIV knowledge, sexual risk and preventive behaviours.

Liver venous deprivation (LVD) before extended hepatectomy: a French multicentric retrospective cohort.

Background: Post-hepatectomy liver failure (PHLF) is the first cause of death after major hepatectomy, and future liver remnant (FLR) volume is the main factor predicting PHLF. Liver venous deprivation (LVD) via portal and hepatic vein embolization has been suggested to induce a better hypertrophy of the FLR than portal vein embolization. The aim of this retrospective multicentric study was to assess safety, feasibility and efficacity of LVD in a French national multicentric register.

Liver transplantation: Do not abandon T-tube drainage-a multicentric retrospective study of the ARCHET research group.

Biliary complications remain a real issue in liver transplantation (LT). Despite meta-analyses, the anastomosis technique, especially the use of biliary drain as T-Tube drain (TT) or transcystic drain, remains controversial. This study conducted by the ARCHET research group examine the incidence and types of biliary complications (BC) after LT according to the presence or absence of a biliary drain.

Role of artificial intelligence in haematolymphoid diagnostics.

The advent of digital pathology and the deployment of high-throughput molecular techniques are generating an unprecedented mass of data. Thanks to advances in computational sciences, artificial intelligence (AI) approaches represent a promising avenue for extracting relevant information from complex data structures. From diagnostic assistance to powerful research tools, the potential fields of application of machine learning techniques in pathology are vast and constitute the subject of considerable research work.

Follicular lymphoma comprises germinal center-like and memory-like molecular subtypes with prognostic significance.

A robust prognostic and biological classification for newly diagnosed follicular lymphoma (FL) using molecular profiling remains challenging. FL tumors from patients treated in the RELEVANCE trial with rituximab-chemotherapy (R-chemo) or rituximab-lenalidomide (R2) were analyzed using RNA sequencing, DNA sequencing, immunohistochemistry (IHC), and/or fluorescence in situ hybridization. Unsupervised gene clustering identified 2 gene expression signatures (GSs) enriched in normal memory (MEM) B cells and germinal center (GC) B-cell signals, respectively.

Co-expression of CD69, CD49d, CD279 and CD20 in chronic lymphocytic leukemia cells is a new biomarker of active disease before or under therapy.

Adherence to cardiovascular medications and risk of cardiovascular disease in breast cancer patients: A causal inference approach in the Pathways Heart Study.

Purpose: Women with breast cancer (BC) are at high risk of developing cardiovascular disease (CVD). We examined adherence to CVD medications and their association with major CVD events over 14 years of follow-up in the Pathways Heart Study, a prospective study of 4,776 stage I-III BC patients diagnosed from 2005-2013.

Methods: Eligibility included being alive 6 months post-BC diagnosis, with dyslipidemia, hypertension, or diabetes at diagnosis along with ≥1 prior outpatient order or dispensing for a statin, anti-hypertensive, or diabetes medication, respectively, in the 30 months prior.

MYC Rearrangement Prediction From LYSA Whole Slide Images in Large B-Cell Lymphoma: A Multicentric Validation of Self-supervised Deep Learning Models.

Large B-cell lymphoma (LBCL) is a heterogeneous lymphoid malignancy in which MYC gene rearrangement (MYC-R) is associated with a poor prognosis, prompting the recommendation for more intensive treatment. MYC-R detection relies on fluorescence in situ hybridization method which is time consuming, expensive, and not available in all laboratories. Automating MYC-R detection on hematoxylin-and-eosin-stained whole slide images of LBCL would decrease the need for costly molecular testing and improve pathologists' productivity.

Blood Pressure and Cardiovascular Risk in Women With Breast Cancer: The Pathways Heart Study.

Background: Hypertension is an important contributor to cardiovascular disease (CVD) in breast cancer (BC) survivors; however, research on blood pressure (BP) and CVD outcomes in BC survivors is limited.

Objectives: The purpose of this study was to better characterize the association between BP and CVD in a large, longitudinal cohort of BC patients.

Methods: Women with invasive BC diagnosed from 2005 to 2013 at Kaiser Permanente Northern California were matched 1:5 to women without BC.

Comprehensive Review of Future Liver Remnant (FLR) Assessment and Hypertrophy Techniques Before Major Hepatectomy: How to Assess and Manage the FLR.

Background: The regenerative capacities of the liver and improvements in surgical techniques have expanded the possibilities of resectability. Liver resection is often the only curative treatment for primary and secondary malignancies, despite the risk of post-hepatectomy liver failure (PHLF). This serious complication (with a 50% mortality rate) can be avoided by better assessment of liver volume and function of the future liver remnant (FLR).

The landscape of use of NCCN-guideline chemotherapy regimens in stage I-IIIA breast cancer in an integrated healthcare delivery system.

Purpose: The National Comprehensive Cancer Network (NCCN) guidelines recommend a variety of drug combinations with specific administration schedules for the treatment of early-stage breast cancer, allowing physicians to deliver treatments recognizing individual patient complexities, including comorbidities, and patient-physician preference. While use of guideline regimens has shifted over time, there is little data to describe changes in how treatment for early-stage breast cancer has evolved over time.

Methods: In a cohort of 34,109 women treated for stage I-IIIA breast cancer between 2006-2019 at Kaiser Permanente Northern California and Kaiser Permanente Washington, we present the changes in chemotherapy regimens over time, and explore use of NCCN-guideline regimens (GR), guideline regimens used when said regimens were not included in guidelines, referred to as time-discordant regimens (TDR), and non-guideline regimens (NGR).
