ABSTRACT
OBJECTIVE: The purpose of this study is to analyze the changes in inflammatory markers and efficacy in the treatment of senior patients with type 2 diabetes mellitus (T2DM) and community-acquired pneumonia with continuous subcutaneous insulin infusion (CSII). METHODS: A total of 105 senior patients with T2DM and community-acquired pneumonia, were randomly divided into two groups, viz., treatment group and control group-52 patients in the treatment group were treated with CSII, and 53 patients in the control group with multiple daily insulin injections (MDI). The changes in fasting blood glucose, postprandial blood glucose, total number of white blood cells, neutrophils, percentage of neutrophils, lymphocytes, percentage of lymphocytes, C-reactive protein, serum amyloid A, procalcitonin, interleukin-6 indexes, and the improvement in clinical outcome between the two groups were compared on the 5th and the 10th day of treatment. RESULTS: In the treatment group, there were 52 patients with an average age of (73.7 ± 8.5) years, which included 28 males and 24 females. In the control group, there were 53 patients, with 27 males and 26 females, with an average age of (74.8 ± 8.8) years. On the 5th and the 10th day of the treatment, the fasting blood glucose, postprandial blood glucose, total number of white blood cells, neutrophils, percentage of neutrophils, lymphocytes, percentage of lymphocytes, C-reactive protein, serum amyloid A, procalcitonin and interleukin-6 of the treatment group were better than that of the control group (P < 0.05). The use of CSII was associated with a higher probability of a prompt recovery (P < 0.05). CONCLUSION: The administration of CSII in the treatment of senior patients with T2DM and community-acquired pneumonia can effectively control fasting and postprandial blood glucose, significantly reduce the levels of inflammatory markers, and improve infection treatment efficacy.

Background: Patients with initially unresectable colorectal cancer liver metastases (IU-CRLM) might benefit from using an effective systemic treatment followed by resection of liver metastases but the curative success rate is quite low. Indeed, nearly one-third of patients exhibit early recurrence within the first 6 months after surgery, and these individuals often have poor overall survival. Objectives: This study aims to clarify the application value of serial circulating tumor DNA (ctDNA) analysis in predicting the clinical outcome of IU-CRLM patients following liver metastasectomy. Design: A retrospective study was conducted on a cohort of patients with IU-CRLM between February 2018 and April 2021. Methods: Plasma samples at different time points during CRLM treatment [baseline (BL), preoperation (PRE), postoperation (POST), end-of-treatment (EOT), and progressive disease (PD)] were retrospectively collected from patients with initially unresectable CRLM enrolled at the Sun Yat-sen University Cancer Center. Dynamic changes of SEPTIN 9 (SEPT9) and Neuropeptide Y (NPY) methylated circulating tumor DNA (MetctDNA) levels in serial plasma samples were detected using droplet-digital PCR (ddPCR). Results: SEPT9 and NPY genes were hypermethylated in colon cancer cell lines and tissues while no difference was observed between primary and metastatic tumors. Patients with MetctDNA positive at POST or EOT had significantly lower recurrence-free survival (RFS) compared to patients with MetctDNA negative at these time points [POST: Hazard ratio (HR) 9.44, 95% confidence interval (CI) 5.15-17.30, p < 0.001; EOT: HR 11.48, 95% CI 3.27-40.31, p < 0.001]. Multivariate analysis demonstrated that POST (OR 33.96, 95% CI 4.03-286.10, p = 0.001) and EOT (OR 18.36, 95% CI 1.14-295.71, p = 0.04) MetctDNA was an independent risk factor for early recurrence. Time-dependent receiver operating characteristic curve (T-ROC) analysis revealed that area under the curve (AUC) value was greatest at the relapse time point of 6 months post-intervention, with POST-AUC and EOT-AUC values of 0.74 (95% CI 0.66-0.81) and 0.73 (95% CI 0.53-0.94), respectively. Serial MetctDNA analysis showed that RFS was significantly lower in patients with no MetctDNA clearance compared with those with MetctDNA clearance (HR 26.05, 95% CI 4.92-137.81, p < 0.001). Conclusion: Our study confirmed that serial ctDNA analysis of NPY and SEPT9 gene methylation could effectively predict early recurrence in IU-CRLM patients, especially at POST and EOT.
