Chimeric antigen receptor and bispecific T-cell engager therapies in multiple myeloma patients with prior allogeneic transplantation.

Chimeric antigen receptor T-cell (CAR-T) therapy and bispecific T-cell engagers (BsAb) have emerged as promising immunotherapeutic modalities in patients with relapsed and/or refractory multiple myeloma (RRMM). However, there is limited data on the safety and efficacy of CAR-T and BsAb therapies in MM patients with a prior history of allogeneic transplantation (allo-HCT). Thirty-three MM patients with prior allo-HCT received CAR-T (n = 24) or BsAb (n = 9) therapy. CAR-T therapy demonstrated an ORR of 92% (67% ≥ CR), and 73% were MRD negative. BsAb therapy resulted in an ORR of 44% (44% ≥ CR) and 44% MRD negative. Safety analysis showed grade ≥3 AEs in 92% of CAR-T and 56% of BsAb patients. Cytokine release syndrome (CRS) occurred in 83% of CAR-T and 78% of BsAb recipients, while immune effector cell-associated neurotoxicity syndrome (ICANS) was observed in three CAR-T patients. Infections of grade ≥3 were reported in 50% of CAR-T and 44% of BsAb recipients. No exacerbation of graft-versus-host disease occurred except in one BsAb recipient. CAR-T and BsAb therapies appear to be feasible, safe and provide deep and durable responses in MM patients with prior allo-HCT.

Health Beliefs and Barriers to Healthcare of Rohingya Refugees.

In recent years, over 1,000 Rohingya families have been resettled to Milwaukee, Wisconsin from areas where they faced trauma and health disparities. To better understand their health beliefs and barriers to healthcare, we conducted a qualitative study with ten community health workers and stakeholders serving the Milwaukee Rohingya community. Interviews were transcribed, coded, and analyzed. Themes included: 1) health is defined as being able to meet basic needs of the family/community; 2) prior and existing mistrust and fear of systems of authority impact healthcare seeking behavior; 3) past-trauma negatively impacts physical and mental health; 4) religion and spirituality influence beliefs about illness, recovery, and wellbeing; 5) linguistic, cultural, and educational barriers impact access, quality of care, and understanding of disease. These results begin to address the significant gap in our knowledge of the health beliefs and needs of the local Rohingya community and underscore the need for tailored interventions.

Seasonal plasticity in GABAA signaling is necessary for restoring phase synchrony in the master circadian clock network.

Annual changes in the environment threaten survival, and numerous biological processes in mammals adjust to this challenge via seasonal encoding by the suprachiasmatic nucleus (SCN). To tune behavior according to day length, SCN neurons display unified rhythms with synchronous phasing when days are short, but will divide into two sub-clusters when days are long. The transition between SCN states is critical for maintaining behavioral responses to seasonal change, but the mechanisms regulating this form of neuroplasticity remain unclear. Here we identify that a switch in chloride transport and GABAA signaling is critical for maintaining state plasticity in the SCN network. Further, we reveal that blocking excitatory GABAA signaling locks the SCN into its long day state. Collectively, these data demonstrate that plasticity in GABAA signaling dictates how clock neurons interact to maintain environmental encoding. Further, this work highlights factors that may influence susceptibility to seasonal disorders in humans.
