AI Article Synopsis
- The study aimed to evaluate the effectiveness of combining levofloxacin with G-CSF against using G-CSF alone in preventing infections following autologous stem cell transplants (ASCT) in patients with blood cancers.
- A retrospective analysis of 102 patients was conducted to compare the rates of febrile neutropenia, bacterial infections, hospital stay lengths, costs, and post-transplant survival between the two treatment groups (levofloxacin+G-CSF vs. G-CSF only).
- Results showed no significant difference in infection rates or hospitalization metrics between the two groups, suggesting that adding levofloxacin may not provide additional benefits in preventing infections during ASCT.
Article Abstract
Objective: To investigate the role of levofloxacin combined with recombinant human granulocyte colony-stimulating factor (G-CSF) or only G-CSF supportive therapy in preventing infection in autologous hematopoietic stem cell transplantation(ASCT), and to analyze the length of hospital stay, hospitalization cost and post-transplant survival of the patients.
Methods: A retrospective analysis was performed in the patients with hematological malignancies who accepted ASCT at our hospital from January 2012 to July 2022, the febrile neutropenia, the incidence of bacterial infection and the use rate of intravenous antibiotics in the levofloxacin+G-CSF group and only G-CSF support group during ASCT were observed. The length of hospital stay, total cost during hospitalization and survival after 90 days of transplantation between the two groups were compared.
Results: A total of 102 cases were included in this study, including 57 cases of multiple myeloma, 36 cases of acute leukaemia, 7 cases of lymphoma, 3 cases of myelodysplastic syndrome, 1 case of light chain amyloidosis, and 1 case of POEMS syndrome. 47 patients received levofloxacin+ G-CSF antibacterial prophylaxis, and 55 patients received G-CSF supportive therapy. In the levofloxacin+ G-CSF group, 40 cases (85.11%) developed febrile neutropenia, and 13 cases (27.66%) were confirmed as bacterial infection. In the G-CSF group, 44 cases (80.00%) developed febrile neutropenia, and 16 cases (29.09%) were bacterial infection. There was no statistically significant difference in the incidence of febrile neutropenia and bacterial infection between the two groups (χ=0.46， =0.50; χ=0.03， =0.87). The use rate of intravenous antibiotics in the levofloxacin+ G-CSF group was 85.11% (40/47), which was not statistically different from 85.45% (47/55) in the G-CSF group (χ=0.04， =0.84). The detection rates of levofloxacin-resistant bacteria in the levofloxacin+ G-CSF group and G-CSF group were 8.57% (3/35) and 21.43% (6/28), respectively, with no statistical difference (χ=0.65, >0.05). The median length and median cost of hospitalization in the levofloxacin+ G-CSF group and G-CSF group were 25 d 22 d and 78 216.24 yuan 80 724.38 yuan, with no statistically significant differences ( =3.00， =0.09; =0.94， =0.09). Within 90 days after transplantation, two cases (4.26%) died in the levofloxacin+ G-CSF group and one case (1.82%) died in the G-CSF group, with no statistically significant difference between the two groups (χ=0.53， =0.47).
Conclusion: Application of levofloxacin+ G-CSF showed no significant benefit compared to G-CSF support for the prevention of bacterial infections during ASCT.

Effectiveness and cytokine profile of combined anti-vascular endothelial growth factor and corticosteroid therapy for chronic retinal vein occlusion.

Department of Ophthalmology and Micro-Technology, Yokohama City University, 4-57 Urafunecho, Minami-ku, Yokohama, 232-0024, Kanagawa, Japan.
Purpose: To investigate whether sub-Tenon injection of triamcinolone acetonide (STTA) combined with anti-vascular endothelial growth factor (VEGF) prolongs the recurrence intervals of macular edema (ME) for chronic retinal vein occlusion (RVO) and to investigate the differences in intraocular inflammatory cytokines between good responders (GRs) and non-responders (NRs).
Methods: This retrospective, observational study involved 42 eyes of 42 patients with ME due to chronic RVO who had received only anti-VEGF for ≥ 1 year and were transitioned to combination therapy. GRs were defined as patients whose recurrence intervals were prolonged by ≥ 2 weeks compared with patients receiving anti-VEGF alone.

Purpose: BMS-986299 is a first-in-class, NOD-, LRR-, and pyrin-domain containing-3 (NLRP3) inflammasome agonist enhancing adaptive immune and T-cell memory responses.
Materials And Methods: This was a phase-I (NCT03444753) study that assessed the safety and tolerability of intra-tumoral BMS-986299 monotherapy (part 1A) and in combination (part 1B) with nivolumab, and ipilimumab in advanced solid tumors. Reported here are single-center results.

Background: Trilaciclib is a transient cyclin-dependent kinase 4/6 (CDK4/6) inhibitor that reduces the incidence of chemotherapy-induced myelosuppression (CIM). In this pooled analysis, we evaluated the multilineage myeloprotection, antitumor efficacy, and safety of trilaciclib treatment in patients with extensive-stage small-cell lung cancer (ES-SCLC). Moreover, myeloprotection effect in 1 L, 2 L/3 L population and effect by risk category were explored.

Introduction: Perinatal management of gastroschisis remains a subject of substantial research. Current models, including teratogenic, genetic, and surgical approaches, often fail to accurately replicate gastroschisis, exhibiting limitations such as inaccurate phenotyping, low success rates, high mortality, lack of scientific validation, and significant technical challenges. Refined disease models are essential for improving the understanding of GS.

Autologous hematopoietic stem cell transplantation is used to restore bone marrow function after high-dose chemotherapy. For apheresis, granulocyte colony-stimulating factor (G-CSF) is standard of care, but obtaining sufficient stem cells can be challenging. Other mobilization agents include plerixafor and PEGylated G-CSF (PEG-G-CSF).
