Immunologic Predictors of Vaccine Responsiveness in Patients With Lymphoma and Chronic Lymphocytic Leukemia.

Patients with B-cell lymphomas have altered cellular components of vaccine responses due to malignancy and therapy, and the optimal timing of vaccination relative to therapy remains unknown. Severe acute respiratory syndrome coronavirus 2 vaccines created an opportunity for new insights in vaccine timing because patients were challenged with a novel antigen across multiple phases of treatment. We studied serologic messenger RNA vaccine response in retrospective and prospective cohorts with lymphoma and chronic lymphocytic leukemia, paired with clinical and research immune parameters.

Efficacy of an mHealth-delivered behavioral intervention on weight loss and cardiometabolic risk in African American postpartum people with overweight or obesity: the SnapBack randomized controlled trial.

Objective: The objective of this study was to evaluate the efficacy of a mobile health (mHealth)-delivered behavioral intervention on changes in postpartum weight and cardiometabolic risk factors (blood pressure [BP], lipids, and hemoglobin A1c) over 12 months.

Methods: A randomized controlled trial of 300 African American postpartum people with overweight and obesity enrolled in Philadelphia Women, Infants, and Children (WIC) clinics was conducted. Participants were randomized to usual WIC care (n = 151) or a 12-month mHealth-delivered intervention (n = 149) comprising behavior change goals, interactive self-monitoring text messages, and counseling support.

Activating A1 adenosine receptor signaling boosts early pulmonary neutrophil recruitment in aged mice in response to Streptococcus pneumoniae infection.

Background: Streptococcus pneumoniae (pneumococcus) is a leading cause of pneumonia in older adults. Successful control of pneumococci requires robust pulmonary neutrophil influx early in infection. However, aging is associated with aberrant neutrophil recruitment and the mechanisms behind that are not understood.

No Consistent Antidepressant Effects of Deep Brain Stimulation of the Bed Nucleus of the Stria Terminalis.

Background: Applying deep brain stimulation (DBS) to several brain regions has been investigated in attempts to treat highly treatment-resistant depression, with variable results. Our initial pilot data suggested that the bed nucleus of the stria terminalis (BNST) could be a promising therapeutic target.

Objective: The aim of this study was to gather blinded data exploring the efficacy of applying DBS to the BNST in patients with highly refractory depression.
