Major evolutionary transitions, such as the shift of cetaceans from terrestrial to marine life, can put pressure on sensory systems to adapt to a new set of relevant stimuli. Relatively little is known about the role of smell in the evolution of mysticetes (baleen whales). While their toothed cousins, the odontocetes, lack the anatomical features to smell, it is less clear whether baleen whales have retained this sense, and if so, when the pressure on olfaction diverged in the cetacean evolutionary lineage.

Article Synopsis
  • * A study analyzing 667 bone marrow harvests between 1999 and 2021 found a 13% contamination rate, primarily from common skin bacteria, with male donors showing significantly higher contamination rates (18% vs. 6.8% for females).
  • * The research is notable for being the largest single-center study to explore contamination rates and highlights male donor sex as a key factor, potentially due to differences in skin flora.

Article Synopsis
  • - The study investigates how positive psychological well-being (PPWB) relates to mood and quality of life in people who have undergone hematopoietic stem cell transplantation (HSCT), using data from 158 recipients.
  • - Results indicate that older age, greater social support, and certain health conditions correspond with higher PPWB levels, which are linked to improved quality of life and reduced symptoms of PTSD, anxiety, and depression.
  • - The researchers suggest that future studies should explore these associations over time to better understand how PPWB affects HSCT recovery and to develop targeted interventions for improving patient outcomes.

Acute graft-versus-host disease (GVHD) is a significant complication following hematopoietic stem cell transplantation (HCT). Although recent advancements in GVHD prophylaxis have resulted in successful HCT across HLA barriers and expanded access to HCT for racial minorities, less is known about how race affects the severity and outcomes of acute GVHD. This study examines differences in the clinical course of acute GVHD and the prognostic value of GVHD biomarkers for Black and White recipients.

Hematopoietic stem cell transplant (HSCT) survivors frequently experience persistent sexual dysfunction, which is associated with impaired quality of life and increased psychological distress. The lack of availability of clinicians with expertise in sexual health limits the capacity to address sexual health concerns in HSCT survivors. Digital health applications may offer a patient-centered and scalable solution to address sexual health concerns in cancer survivors.

The relative importance of various sensory modalities can shift in response to evolutionary transitions, resulting in changes to underlying gene families encoding their reception systems. The rapid birth-and-death process underlying the evolution of the large olfactory receptor (OR) gene family has accelerated genomic-level change for the sense of smell in particular. The transition from the land to sea in marine mammals is an attractive model for understanding the influence of habitat shifts on sensory systems, with the retained OR repertoire of baleen whales contrasting with its loss in toothed whales.

PURPOSEAccess to allogeneic hematopoietic cell transplantation (HCT) remains limited among persons of non-European ancestry if human leukocyte antigen (HLA) matching is required. We evaluated whether post-transplant cyclophosphamide (PTCy)-based graft-versus-host disease (GVHD) prophylaxis improved HCT outcomes with HLA-matched unrelated donor (MUD) and mismatched unrelated donor (MMUD) HCT when compared with calcineurin inhibitor (CNI)-based prophylaxis.METHODSThree-year overall survival (OS) and GVHD-free, relapse-free survival (GRFS) were compared between adult recipients undergoing initial MUD or single HLA locus MMUD HCT with either PTCy- or CNI-based prophylaxis who were reported to the Center for International Blood and Marrow Transplant Research between 2017 and 2021.

Disruption of the intestinal microbiome is observed with acute graft-versus-host disease (GVHD) of the lower gastrointestinal (LGI) tract, and fecal microbiota transplantation (FMT) has successfully cured steroid-refractory cases. In this open-label, single-arm, pilot study, third-party, single-donor FMT was administered in combination with systemic corticosteroids to participants with high-risk acute LGI GVHD, with a focus on treatment-naïve cases. Participants were scheduled to receive 1 induction dose (15 capsules per day for 2 consecutive days), followed by 3 weekly maintenance doses, consisting of 15 capsules per dose.

Caregivers of patients undergoing chimeric antigen receptor T cell therapy (CAR-T) play a critical role during treatment, yet their experience remains largely unaddressed. We aimed to longitudinally describe quality of life (QoL) and psychological distress, as well as prognostic awareness, in caregivers and explore the association of prognosis awareness with baseline psychological distress. We conducted a longitudinal study of caregivers of patients undergoing CAR-T and examined QoL (CAReGiverOncology QoL questionnaire) and psychological distress (Hospital Anxiety and Depression Scale) prior to CAR-T (baseline) and at days 7, 30, 90, and 180 post-CAR-T.
