A beneficial effect in mean change of pain intensity at rest was seen in the group receiving 0.75 mg ml-1 S-ketamine in oxycodone PCA compared with patients receiving lower ketamine doses or oxycodone alone (standardized effect size 0.17, 95% CI 0.013-0.32, P = 0.033). The occurrence of adverse events was similar among the groups. Oxycodone PCA containing S-ketamine as an adjunct at a ratio of 1 0.75 decreased cumulative oxycodone consumption at 24 h after major lumbar spinal fusion surgery without additional adverse effects. Oxycodone PCA containing S-ketamine as an adjunct at a ratio of 1 0.75 decreased cumulative oxycodone consumption at 24 h after major lumbar spinal fusion surgery without additional adverse effects. Whether dynamic changes of metabolic syndrome (MetS) affects the subsequent laryngeal cancer occurrence remains unknown. This study investigated the effects of changes of MetS on the incidence of laryngeal cancer due to a lack of knowledge regarding the development of MetS in Korean population. A total of 6,757,048 individuals who received national health checkup in 2009 and follow-up health examination in 2011 were analyzed and followed up until 2018. MetS status included the following categories MetS-chronic (n = 941,609), MetS-developed (n = 614,229), MetS-recovery (n = 455,835), and MetS-free (n = 4,745,375). With a median follow-up duration of 6.403 years, 1,350 subjects were newly diagnosed with laryngeal cancer. Compared to participants without MetS, adjusted hazard ratios (HR) (95% confidence interval) for those with MetS were 1.320 (1.17-1.489) for laryngeal cancer. The HR of laryngeal cancer was found to be increased with increasing number of MetS components. The MetS-deve
