Background: Deep neuromuscular blockade (NMB) optimizes surgical conditions, particularly during laparoscopic procedures. However, its effects on systemic cytokines associated with anesthesia-related complications, including postoperative delirium and cognitive dysfunction, remain unclear. In this review, we quantified the impact of deep NMB on serum cytokine levels. Methods: PubMed, EMBASE, CENTRAL, CINAHL, Scopus, Web of Science, and Google Scholar databases were searched to identify randomized controlled trials (RCTs) evaluating serum cytokine levels in surgical patients under deep or moderate NMB. Results: Eight RCTs, including 661 patients undergoing laparoscopic and orthopedic surgeries, met the inclusion criteria. Immediately postoperatively, meta-analysis suggested a potential reduction in tumor necrosis factor-α (TNF-α, standardized mean difference: −0.46, 95% CI [−0.87 to −0.06], P = 0.03), with no significant differences in interleukin-1β (IL-1β) or interleukin-6 (IL-6) levels. At 24-h and 48-h postoperatively, no significant differences were observed in IL-1β, IL-6, TNF-α, or C-reactive protein levels. Meta-regression analysis indicated that inhalational anesthesia was associated with high IL-1β (estimate = 1.2135, 95% CI [0.5107–1.9162], P < 0.01) and TNF-α levels (estimate = 0.6271, 95% CI [0.0544–1.1997], P = 0.032) immediately postoperatively; however, younger patients exhibited elevated IL-1β levels under moderate NMB at 24-h postoperatively (estimate = 0.0242, 95% CI [0.0065–0.0419], P < 0.01). Conclusions Deep NMB may be associated with reduced TNF-α levels immediately postoperatively. Inhalational anesthesia and younger age may contribute more to higher serum cytokine levels compared with total intravenous anesthesia and older age, respectively, suggesting a potential immunomodulatory effect of deep NMB. Further studies should clarify its clinical relevance.

Background: Maintenance of stable blood pressure (BP) during cerebrovascular bypass surgery is crucial to prevent cerebral ischemia. We compared the effect of remimazolam anesthesia with that of propofol-induced and desflurane-maintained anesthesia on intraoperative hemodynamic stability and the need for vasoactive agents in patients undergoing cerebrovascular bypass surgery. Methods: Sixty-five patients were randomized into remimazolam (n = 31, remimazolam-based intravenous anesthesia) and control groups (n = 34, propofol-induced and desflurane-maintained anesthesia). The primary outcome was the occurrence of intraoperative hypotension. The secondary outcomes included hypotension duration, lowest mean BP (MBP), generalized average real variability (ARV) of MBP, and consumption of phenylephrine, norepinephrine, or remifentanil. Results: Occurrence rate and duration of hypotension were significantly lower in the remimazolam group (38.7% vs. 73.5%, P = 0.005; 0 [0, 10] vs. 7.5 [1.25, 25] min, P = 0.008). Remimazolam also showed better outcomes for lowest MBP (78 [73, 84] vs. 69.5 [66.25, 75.8] mmHg, P < 0.001) and generalized ARV of MBP (1.42 ± 0.49 vs. 1.66 ± 0.52 mmHg/min, P = 0.036). The remimazolam group required less phenylephrine (20 [0, 65] vs. 100 [60, 130] μg, P < 0.001), less norepinephrine (162 [0, 365.5] vs. 1335 [998.5, 1637.5] μg, P < 0.001), and more remifentanil (1750 [1454.5, 2184.5] vs. 531 [431, 746.5] μg, P < 0.001) than the control group. Conclusions Remimazolam anesthesia may provide better hemodynamic stability during cerebrovascular bypass surgery than propofol-induced and desflurane-maintained anesthesia.

Background: The Jr a antigen is a high-prevalence red blood cell (RBC) antigen. Reports on cases of fatal hemolytic disease of the fetus and newborn and acute hemolytic transfusion reactions suggest that antibodies against Jr a (anti-Jra ) have potential clinical significance.Identifying anti-Jra is challenging owing to a lack of commercially available antisera. We developed an alternative approach to rapidly predict the presence of anti-Jra using the TaqMan single-nucleotide polymorphism (SNP)-genotyping method. Methods: Residual peripheral blood samples from 10 patients suspected of having the anti-Jr a were collected. Two samples with confirmed Jr(a–) RBCs and anti-Jra were used to validate the TaqMan genotyping assay by comparing the genotyping results with direct sequencing. The accuracy of the assay in predicting the presence of anti-Jra was verified through crossmatching with in-house Jr(a–) O+ RBCs. Results: The TaqMan-genotyping method was validated with two Jr(a–) RBC- and anti-Jra -confirmed samples that showed concordant Jr a genotyping and direct sequencing results.Jra genotyping for the remaining samples and crossmatching the serum samples with inhouse Jr(a–) O+ RBCs showed consistent results. Conclusions We validated a rapid, simple, accurate, and cost-effective method for predicting the presence of anti-Jra using a TaqMan-based SNP-genotyping assay. Implementing this method in routine practice in clinical laboratories will assist in solving difficult problems regarding alloantibodies to high-prevalence RBC antigens and ultimately aid in providing safe and timely transfusions and proper patient care.

Background: Structural variants (SVs) are currently analyzed using a combination of conventional methods; however, this approach has limitations. Optical genome mapping (OGM), an emerging technology for detecting SVs using a single-molecule strategy, has the potential to replace conventional methods. We compared OGM with conventional diagnostic methods for detecting SVs in various hematologic malignancies. Methods: Residual bone marrow aspirates from 27 patients with hematologic malignancies in whom SVs were observed using conventional methods (chromosomal banding analysis, FISH, an RNA fusion panel, and reverse transcription PCR) were analyzed using OGM. The concordance between the OGM and conventional method results was evaluated. Results: OGM showed concordance in 63% (17/27) and partial concordance in 37% (10/27) of samples. OGM detected 76% (52/68) of the total SVs correctly (concordance rate for each type of SVs: aneuploidies, 83% [15/18]; balanced translocation, 80% [12/15] unbalanced translocation, 54% [7/13] deletions, 81% [13/16]; duplications, 100% [2/2] inversion 100% [1/1]; insertion, 100% [1/1]; marker chromosome, 0% [0/1];isochromosome, 100% [1/1]). Sixteen discordant results were attributed to the involvement of centromeric/telomeric regions, detection sensitivity, and a low mapping rate and coverage. OGM identified additional SVs, including submicroscopic SVs and novel fusions, in five cases. Conclusions OGM shows a high level of concordance with conventional diagnostic methods for the detection of SVs and can identify novel variants, suggesting its potential utility in enabling more comprehensive SV analysis in routine diagnostics of hematologic malignancies, although further studies and improvements are required.
