Local Scale Biogeographic Variation in the Magnolia () Phyllosphere.

The phyllosphere (aerial plant surfaces colonized by microorganisms) remains an understudied ecosystem in terms of bacterial biogeography, particularly at intermediate or local spatial scales. This study characterized the phyllosphere bacterial community on the leaves of 87 trees sampled throughout a small town, encompassing an area of approximately 60 km. Sequencing of the 16S ribosomal RNA gene revealed the dominant bacterial phyla to be Alphaproteobacteria, Bacteroidetes, and Acidobacteria, consistent with other studies of the phyllosphere.

Period Poverty: An Epidemiologic and Biopsychosocial Analysis.

In the United States, approximately one in five persons experience period poverty, defined as the inability to obtain resources needed for healthy, safe, and dignified menstrual management. Limited access to an inadequate number of menstrual supplies may lead to longer-than-recommended use, which can increase skin chafing, disruption of vaginal flora, and intravaginal toxin overgrowth. However, period poverty goes beyond simply having enough menstrual products and can encompass the embarrassment, stigma, shame, and barriers in conversation surrounding menstruation.

Survival following allogeneic transplant in patients with myelofibrosis.

Allogeneic hematopoietic cell transplantation (HCT) is the only curative therapy for myelofibrosis (MF). In this large multicenter retrospective study, overall survival (OS) in MF patients treated with allogeneic HCT (551 patients) and without HCT (non-HCT) (1377 patients) was analyzed with Cox proportional hazards model. Survival analysis stratified by the Dynamic International Prognostic Scoring System (DIPSS) revealed that the first year of treatment arm assignment, due to upfront risk of transplant-related mortality (TRM), HCT was associated with inferior OS compared with non-HCT (non-HCT vs HCT: DIPSS intermediate 1 [Int-1]: hazard ratio [HR] = 0.

Cellular stressors contribute to the expansion of hematopoietic clones of varying leukemic potential.

Hematopoietic clones harboring specific mutations may expand over time. However, it remains unclear how different cellular stressors influence this expansion. Here we characterize clonal hematopoiesis after two different cellular stressors: cytotoxic therapy and hematopoietic transplantation.
