To assess the surgical outcomes in patients who underwent femtosecond laser-assisted lamellar keratoplasty with double continuous suture for keratoconus, 100 patients (102 eyes) with keratoconus in advanced stages undergoing femtosecond laser-assisted lamellar keratoplasty in Shandong Eye Hospital were studied. In the management of keratoconus, 50 patients (52 eyes) received double continuous suture, and 50 patients (50 eyes) underwent interrupted suture. The follow-up duration was 1 year. Best-corrected visual acuity (BCVA), corneal astigmatism, cosmetic outcomes, and surgical complications were measured as outcome indicators. find more The epithelium healed at 3 ± 2 days and 4 ± 2 days in the double continuous suture group and the interrupted suture groups, respectively (P > 0.05). At 6 months after surgery, the average visual acuity was 20/125 and 20/100 (P > 0.05), and the average BCVA was 20/32 and 20/40 (P > 0.05), respectively. At 1 year after surgery, the average visual acuity was 20/63 and 20/80 (P > 0.05), and the average BCVA was 20/32 and 20/25 (P > 0.05), respectively; the mean curvature was 43.24 ± 5.15 D and 43.31 ± 5.58 D (P > 0.05), the mean astigmatism was 3.21 ± 1.74 D and 5.35 ± 1.37 D (P  less then  0.05).The looseness of sutures were found in 2 patients and 15 patients in both groups, respectively (P  less then  0.05). No postoperative infection or immune rejection occurred in either group during the follow-up. Comparing with the interrupted suture, using the continuous suture in femtosecond laser-assisted lamellar keratoplasty for keratoconus markedly limited the looseness of sutures with lesser corneal astigmatism and better visual quality postoperative.There can be a tendency for investigators to disregard or explain away null or negative results in prevention science trials. Examples include not publicizing findings, conducting spurious subgroup analyses, or attributing the outcome post hoc to real or perceived weaknesses in trial design or intervention implementation. This is unhelpful for several reasons, not least that it skews the evidence base, contributes to research "waste", undermines respect for science, and stifles creativity in intervention development. In this paper, we identify possible policy and practice responses when interventions have null (ineffective) or negative (harmful) results, and argue that these are influenced by the intervention itself (e.g., stage of gestation, perceived importance); trial design, conduct, and results (e.g., pattern of null/negative effects, internal and external validity); context (e.g., wider evidence base, state of policy); and individual perspectives and interests (e.g., stake in the intervention). We advance several strategies to promote more informative null or negative effect trials and enable learning from such results, focusing on changes to culture, process, intervention design, trial design, and environment.Up to 30% of patients with classical Hodgkin lymphoma (cHL) are not responsive to frontline therapy or relapse after primary treatment. In these cases, autologous hematopoietic stem cell transplantation (AHSCT) is the standard of care. The combination of brentuximab vedotin and bendamustine (BV + B) is an effective salvage regimen in this challenging subpopulation. This nationwide multicenter study investigated the real-world efficacy and safety of the BV + B regimen as a bridge to AHSCT in patients with primary refractory or relapsed cHL. A total of 41 cHL patients underwent AHSCT after receiving at least 1 cycle of BV + B (with brentuximab vedotin given at 1.8 mg/kg on day 1 and bendamustine at 90 mg/m2 on days 1-2 every 4 weeks). After a median of 3 (1-6) cycles of BV + B, the objective response rate was 78%, with 29 (70.7%) patients achieving complete remission. Twelve (29.3%) patients relapsed after AHSCT, 2 (4.9%) of them died, while 2 (4.9%) patients are lost to follow-up. After a median of 17 months of follow-up, the estimated 2-year overall- and progression-free survival after AHSCT was 93 and 62%, respectively. Features of advanced disease at recurrence (p = 0.038) and the presence of stage IV cHL at relapse (p = 0.024) are strong predictor markers of unfavorable outcomes. Twenty-four (58.5%) patients experienced adverse events of any grade, while no grade IV toxicities were reported. BV + B is an effective salvage option with a manageable toxicity profile in cHL. The real-world safety and efficacy of this combination are similar to the observations made on the study population.A novel bacterial strain, designated HX-9-20T, was isolated from the sediment collected from the wastewater outlet of an agricultural chemical plant in Maanshan city, Anhui province, PR China. Cells of strain HX-9-20T were Gram-staining-negative, rod-shaped, translucent, non-motile, and strictly aerobic. Growth was observed between 15 and 35 °C (optimum 30 °C), at pH 6.0-8.0 (optimum pH 7.0), and in the presence of 0-0.4% (w/v) NaCl (optimum 0.2%). The predominant cellular fatty acids were summed feature 3 (C161 ω7c and/or C161 ω6c), C160 and summed feature 8 (C181 ω6c and/or C181 ω7c). The major quinone was ubiquinone Q-8. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, and an aminophospholipid. Strain HX-9-20T contains 2-hydroxyputrescine and putrescine as the major polyamine. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain HX-9-20T was affiliated with the genus Caenimonas, exhibiting the highest sequence similarities with Caenimonas koreensis EMB320T (97.3% similarity) and Ramlibacter humi 18×22-1T (97.0%), and less than 97.0% similarity with other type strains. The average nucleotide identity (ANI) and digital DNA-DNA hybridization values (dDDH) between HX-9-20T and C. koreensis EMB320T were 76.9% and 23.5% respectively. The ANI and dDDH between HX-9-20T and R. humi 18×22-1T were 80.3% and 23.6%, respectively. The G + C content of the genomic DNA was 67.5 mol%. On the basis of the polyphasic taxonomic data, strain HX-9-20T represents a novel species of the genus Caenimonas, for which the name Caenimonas sedimenti sp. nov. is proposed. The type strain is HX-9-20T (=KCTC 72473T=CCTCC AB 2019266T).
