Multiple myeloma (MM) remains incurable, with poor outcomes in heavily pre-treated patients with plasmacytomas. Chimeric antigen receptor (CAR) T-cell therapy has emerged as a promising treatment option; however, outcomes after such therapy in patients with soft-tissue plasmacytomas and other bone lesions remain poorly understood. Data regarding these parameters is scarce within the specific context of CAR T-cell treatment.

The impact of measurable residual disease (MRD) in relapse/refractory multiple myeloma (RRMM) patients treated with T-cell redirecting immunotherapy is uncertain. We analyzed MRD dynamics using next-generation flow in 201 patients treated in clinical trials with chimeric antigen receptor (CAR) T cells and T-cell engagers (TCE). Achieving MRD negativity at 10 was associated with 89% reduction in the risk of progression and/or death.

Article Synopsis
  • The study investigates how non-genetic factors, especially epigenetics like DNA methylation, contribute to the development of Systemic Sclerosis (SSc).
  • By analyzing DNA methylation data from 179 SSc patients and 241 healthy individuals, researchers identified 525 differentially methylated positions related to immune pathways, particularly those involving leukocyte adhesion.
  • The findings suggest that changes in DNA methylation impact gene expression and highlight the role of myeloid cells and specific transcription factors, opening up new avenues for potential clinical applications in treating SSc.

Background/objectives: Emerging evidence suggests that patients suffering from COVID-19 may experience neurocognitive symptoms. Furthermore, other studies indicate a probable association between leukocyte telomere length (LTL) and neurocognitive changes in subjects with post-COVID-19 condition. Our study was designed to determine the correlation between telomere length and cognitive changes in post-COVID-19 subjects.

Article Synopsis
  • The study examined the impact of immunoparesis (IP) recovery on the prognosis of 113 newly diagnosed transplant-ineligible multiple myeloma (MM) patients who received a fixed treatment regimen and achieved complete or very good partial responses.
  • Results showed that patients who initially had IP and then experienced recovery during or after treatment had significantly longer progression-free survival (PFS) and overall survival (OS) compared to those who did not recover.
  • Additionally, among MRD negative patients, those with IP recovery also demonstrated improved PFS and OS, highlighting that IP recovery can enhance prognostic evaluations in combination with MRD status in this patient population.

Boosting the transport and selectivity properties of membranes based on polymers of intrinsic microporosity (PIMs) toward one specific working analyte of interest is challenging. In this work, a novel family of PIM membranes, prepared by casting and exhibiting optima mechanical properties and high thermal stability, was synthesized from 4,4'-(2,2,2-trifluoro-1-phenylethane-1,1-diyl) bis(benzene-1,2-diol) and two tetrafluoro-nitrile derivatives. Gas permeability measurements evidenced a CO/CH selectivity up to 170% relative to the reference polymer, PIM-1, in agreement with their calculated fractional free volume and the analysis of the textural properties by N and CO gas adsorption.

Article Synopsis
  • - In a study of 138 multiple myeloma (MM) patients, researchers explored the benefits of monitoring peripheral residual disease (PRD) in blood instead of relying solely on more invasive bone marrow (BM) assessments.
  • - Positive PRD results from next-generation flow (NGF) indicated a significantly higher risk of disease progression/death, and those with undetectable PRD had excellent survival rates.
  • - The findings suggest that PRD monitoring is a valuable and less cumbersome method for identifying patients at risk of relapse during maintenance treatment in transplant-eligible MM patients.

Article Synopsis
  • Many cases of erythrocytosis and thrombocytosis are still classified as "idiopathic" due to factors like lack of secondary causes or inconclusive tests, despite advancements in genetic testing.
  • Next-generation sequencing (NGS) was reviewed in 175 patients, leading to diagnoses in a small number: 5.1% for polycythaemia vera and 6.8% for familial erythrocytosis, with low EPO levels and family history being predictors.
  • The study found a higher success rate in diagnosing thrombocytosis cases, with 25.9% identified as having essential thrombocythemia, but overall, the low variant detection rate suggests the need for comprehensive initial screening before using N

Quantitative immunoprecipitation mass spectrometry (QIP-MS) allows the identification of the M-protein in patients with multiple myeloma (MM) otherwise in complete response, and could be considered suitable for measurable residual disease (MRD) evaluation in peripheral blood. In the context of the GEM2012MENOS65 and GEM2014MAIN trials, we compared the performance of QIP-MS in serum with next-generation flow (NGF) cytometry in bone marrow to assess MRD in paired samples obtained postinduction, transplant, consolidation and after 24 cycles of maintenance. At each time point, both NGF and QIP-MS were able to segregate 2 groups of patients with significantly different progression-free survival; when the evolution of the results obtained with either method was considered, maintaining or converting to MRD negativity was associated with longer survival, significantly better when compared with sustaining or converting to MRD positivity.

Minimal residual disease (MRD) assessment is a known surrogate marker for survival in multiple myeloma (MM). Here, we present a single institution's experience assessing MRD by NGS of Ig genes and the long-term impact of depth of response as well as clonal diversity on the clinical outcome of a large population of MM patients; 482 MM patients at the University of California, San Francisco (UCSF) diagnosed from 2008 to 2020 were analyzed retrospectively. MRD assessment was performed by NGS.

Research Question: What is the profile of women in the USA who become surrogates, and what is their power of decision and motivations?

Design: This quantitative study was performed with 231 participants in the USA, given the country's long history of surrogacy, to help clarify the profile of women who become surrogates, their power of decision and motivations.

Results: Descriptive and multivariate cluster analyses showed that women who become surrogates earn above the average income for their state of residency, have a high level of education, have health insurance, are employed, and decide to become a surrogate for prosocial/altruistic reasons.

Conclusions: In contrast to the premise of both radical feminism and ultra-conservative Catholicism, this study found that altruism and empathy are the primary motivations for participating in surrogacy processes, and that a woman's decision to become a surrogate is not motivated by social conditioning relating to poverty or social status.

The value of quantitative immunoprecipitation mass spectrometry (QIP-MS) to identify the M-protein is being investigated in patients with monoclonal gammopathies but no data are yet available in high-risk smoldering myeloma (HRsMM). We have, therefore, investigated QIP-MS to monitor peripheral residual disease (PRD) in 62 HRsMM patients enrolled in the GEM-CESAR trial. After 24 cycles of maintenance, detecting the M-protein by MS or clonal plasma cells by next-generation flow cytometry (NGF) identified cases with a significantly shorter median progression-free survival (mPFS) (MS: not reached vs.
