Short-term and long-term changes in natriuretic peptide levels after bariatric surgery: a systematic review and meta-analysis.

Bariatric surgery (BS) has demonstrated cardiovascular benefits in patients and was previously proven to be associated with an increased natriuretic peptide level without cardiac dysfunction. However, new studies have emerged, which require us to re-examine the relationship and extent of the correlation between BS, weight loss, and cardiac natriuretic peptide levels. A systematic search was conducted.

Asparagine availability controls germinal center B cell homeostasis.

The rapid proliferation of germinal center (GC) B cells requires metabolic reprogramming to meet energy demands, yet these metabolic processes are poorly understood. By integrating metabolomic and transcriptomic profiling of GC B cells, we identified that asparagine (Asn) metabolism was highly up-regulated and essential for B cell function. Asparagine synthetase (ASNS) was up-regulated after B cell activation through the integrated stress response sensor GCN2.

Hybrid plasmonic valley-Hall topological insulators.

The emerging field of photonic topological insulators offers promising platforms for high-performance optical communication, computing, and sensing. However, conventional photonic topological insulator designs typically operate within the diffraction limit due to their dielectric nature. This limitation imposes constraints on device miniaturization, reduces light-matter interaction, and decreases overall device sensitivity.

Measurable residual mutated IDH1 before allogeneic transplant for acute myeloid leukemia.

Measurable residual disease (MRD) in adults with acute myeloid leukemia (AML) in complete remission is an important prognostic marker, but detection methodology requires optimization. Persistence of mutated NPM1 or FLT3-ITD in the blood of adult patients with AML in first complete remission (CR1) prior to allogeneic hematopoietic cell transplant (alloHCT) associates with increased relapse and death after transplant. The prognostic implications of persistence of other common AML-associated mutations, such as IDH1, at this treatment landmark however remain incompletely defined.

Measurable residual mutated IDH2 before allogeneic transplant for acute myeloid leukemia.

Routine genetic profiling of acute myeloid leukemia (AML) at initial diagnosis has allowed subgroup specific prognostication, drug development, and clinical management strategies. The optimal approach for treatment response assessment for AML subgroups has not yet however been determined. A nationwide cohort of 257 adult patients in first remission (CR1) from AML associated with an IDH2 mutation (IDH2m) undergoing allogeneic transplant during the period 2013-2019 in the United States had rates of relapse and survival three years after transplantation of 24% and 71%, respectively.

A proinflammatory stem cell niche drives myelofibrosis through a targetable galectin-1 axis.

Myeloproliferative neoplasms are stem cell-driven cancers associated with a large burden of morbidity and mortality. Most patients present with early-stage disease, but a substantial proportion progress to myelofibrosis or secondary leukemia, advanced cancers with a poor prognosis and high symptom burden. Currently, it remains difficult to predict progression, and therapies that reliably prevent or reverse fibrosis are lacking.

Insight into the emerging insect to human pathogen revealing geographic differences in immune cell tropism.

Background: is a species of the insect pathogenic genus that has been isolated as an etiological agent in human infections. Since then, multiple isolates have been identified worldwide; however, actual clinical infections have so far only been identified in North America, Australia, and Nepal. Previous research on the clinical isolates had shown that the strains differed in their behaviour when infecting cultured human cells.
