5-Azacytidine is a pyrimidine nucleoside analog of cytidine that undergoes incorporation into DNA and blocks DNA methyltransferase leading to hypomethylation and potentially beneficial re-expression of abnormally silenced genes. It is the first agent approved for use in patients with myelodysplastic syndromes (MDSs) based on its improvement in overall survival as monotherapy. Evidence of efficacy in combination with other agents is also accumulating. Our understanding of the molecular basis and pathogenesis of MDS continues to evolve rapidly. 5-Azacytidine has been shown to improve both overall survival and quality of life in patients with high-risk MDS. Currently, the oral route of administration is undergoing evaluation in clinical trials. Used as a monotherapy and also in novel combinations, 5-azacytidine has the potential to further improve the prognosis of some patients with MDS. [1] Azacitidine is the first drug in a new class of compounds, known as DNA hypomethylating agent...

Measurable residual disease (MRD) is a major prognostic factor in newly diagnosed multiple myeloma. An assessment of an MRD-guided consolidation strategy in patients who are eligible for autologous stem-cell transplantation (ASCT) may be useful. Methods: In this phase 3 trial, we randomly assigned transplantation-eligible patients with newly diagnosed myeloma who had completed induction therapy with isatuximab, carfilzomib, lenalidomide, and dexamethasone (Isa-KRd) to receive consolidation therapy according to their MRD status. Patients who were MRD-negative at 10-5 sensitivity (i.e., <1 cancer cell per 100,000 normal cells, as assessed by next-generation sequencing were assigned to undergo ASCT and receive Isa-KRd for two cycles (ASCT group) or to receive Isa-KRd for six cycles (Isa-KRd group). Patients who were MRD-positive at 10-5 sensitivity were assigned to undergo tandem ASCT (two ASCTs within a short period; tandem ASCT group) or to undergo ASCT and receive Isa-KRd for tw...

Wyeth, the manufacturer of Zosyn, states Lactated Ringer's Solution is compatible only with reformulated Zosyn containing EDTA and is compatible with co-administration via a Y-site. Many generic formulations (e.g., Apotex) do not contain EDTA. [1, 2] Trissel's IV compatibility database notes the older formulation without the added components (most generic products) is incompatible with Lactated Ringer's. Ensure that the newer formulation is the only form of the drug mixed with Lactated Ringer's. [3] A 2019 study that tested the physical compatibility of Lactated Ringer's with 94 medications found incompatibilities with ciprofloxacin, cyclosporine, diazepam, ketamine, lorazepam, nitroglycerin, phenytoin, and propofol after 4 hours at room temperature. This study surprisingly found compatibility with ceftriaxone, amphotericin B, and piperacillin-tazobactam, which all previously were thought to be incompatible with LR (See Tables 1 and 2). [4] The study utilized a formulation of...

We established a dextran sodium sulfate (DSS)-induce BALB/c mice model of IBD and treated with hucMSC-Ex via tail vein to evaluate their repair effect on IBD mice. An in vitro macrophage inflammation model was established using lipopolysaccharide (LPS) and Nigericin (Nig) by stimulating mouse macrophage RAW264.7 and human myeloid leukemia mononuclear (THP-1) cells to assess the repair effect of hucMSC-Ex on macrophage inflammation. EX 527, an effective inhibitor of silent information regulator of transcription 1 (SIRT1), was employed in both the in vivo and in vitro models to explore the effect of hucMSC-Ex on the SIRT1-FXR (farnesoid X receptor) pathway in macrophages during the attenuation of inflammation. HucMSC-Ex effectively inhibited inflammation in both the in vivo and in vitro models by up-regulating the expressions of SIRT1 and FXR, which reduced the acetylation level of FXR and inhibited the activation of NOD-like receptor thermal protein domain associated protein 3 (NLR...

Moreover, TMS was applied during a choice reaction time task to assess changes in motor excitability associated with inhibitory control. Finally, behavioral inhibition was investigated using a neuropsychological task (anti-saccade). Overall, our results highlight several interesting correlations between microbial composition and brain measures. Hence, higher bacterial diversity, as well as higher relative abundances of UGC-002 and Christensenellaceae R-7 group were correlated with stronger changes in motor excitability associated with inhibitory control. Also, higher abundance of Anaerostipes was associated with higher level of corticospinal excitability. Finally, relative abundances of Bifidobacterium and Faecalibacterium were positively related to performance in the neuropsychological task, suggesting that they might have a positive impact on behavioral inhibition. Although correlation is not causation, the present study suggests that excitatory and inhibitory brain processes migh...
