Clinical significance of glomerular IgM deposit in IgA nephropathy: a 5-year follow-up study.

The significance of glomerular IgM deposit intensity in IgA Nephropathy (IgAN) remained ambiguous and requires further research. Patients with biopsy-proven IgAN in our hospital from January 2018 to May 2023 were recruited into this retrospective single-center study. Patients who presented with positive IgM deposit were included in IgM + cohort while patients with negative IgM deposit were included in IgM- cohort. Of the IgM+, patients whose IF intensity of IgM deposits exceeded 1+ formed IgM-H cohort while patients whose IF intensity of IgM deposits was equal to 1+ consisted IgM-L cohort. Pairwise comparisons were performed among these cohorts to determine clinical disparities, following the propensity score matching process. Among 982 IgAN patients, 539 patients presented with positive IgM deposit. The Kaplan-Meier analysis showed that the IgM deposit did not contribute adversely to the outcomes (eGFR decreased from the baseline ≥ 50% continuously or reached end-stage renal disease). However, the Cox regression analysis showed that increased intensity of IgM deposit was an independent risk factor (p = 0.03) in IgM+. The IgM-H exhibited more pronounced segmental glomerulosclerosis (p = 0.02) than the IgM-L, which may also be associated more directly with higher urine protein levels (p = 0.02). Moreover, our generalized linear mixed model demonstrated a remarkably higher urine albumin/creatinine ratio (p < 0.01) and serum creatinine (p = 0.04) levels as well as lower serum albumin (p < 0.01) level in IgM-H persistently during the 5-year follow-up. This study concluded that increased intensity of glomerular IgM deposits may contribute adversely to clinicopathologic presentation and outcome in those IgM + patients.

Hsa_circ_0054633 association of C peptide is related to IL-17 and TNF-α in patients with diabetes mellitus receiving insulin treatment.

BACKGROUND: Chronic inflammation damaged the islet and resulted in dysfunction of T2D. Circular RNA is stable and better for biomarker in many diseases. Here, we aimed to identify potential circular RNA hsa_circ_0054633 that can be a biomarkers for the effects of insulin therapy in T2D. METHODS: In this retrospective case-control study, patients were from Li Huili Hospital, Ningbo, China, from February 10, 2019, to August 15, 2019. We included 47 healthy adults, 46 new-onset T2D with insulin resistance, and 51 patients with insulin therapy. Serum inflammation factors were tested by ELISA assays. We selected hsa_circ_0054633 as a candidate biomarker and measured its concentration in serum by qRT-PCR. The Pearson correlation test was used to evaluate the correlation between this circRNA and clinical variables. RESULTS: Clinical data indicated that serum C peptide was increased in T2D treatment with insulin. Serum hsa_circ_0054633 was decreased in insulin treatment group. Hsa_circ_0054633 was negative correlated with C peptide (r = -0.2841, p = 0.0433,). IL-1 and IL-6, IL-17, and TNF-α were higher in T2D patients and decreased after insulin treatment, only IL-17 and TNF-α showed a positive correlation to hsa_circ_0054633 (r = 0.4825, p < 0.0001, and r = 0.6190, p < 0.0001). The area under ROC curve was 0.7432, 0.5839, and 0.7573 for Hsa_circ_0054633, C peptide, and their combination. CONCLUSION: Hsa_circ_0054633 level was lower in T2D with insulin treatment than untreated and was a negative correlation with C peptide, and positively correlated with IL-17 and TNF-α, suggesting that hsa_circ_0054633 may be a potential early indicator of insulin treatment effect to improve inflammation condition.

Expression of long non-coding RNA H19 in colorectal cancer patients with type 2 diabetes.

The aim of this study was to explore the lncRNAs expression in colorectal cancer (CRC) patients with type 2 diabetes (T2DM) and evaluate the diagnostic value of lncRNAs expression in CRC patients with T2DM. The present study was conducted on two cohorts with CRC patients. The tissues levels of lncRNAs were measured by real-time PCR analysis. The results showed that H19 and MALAT1 expression were higher in CRC tissues than in normal colorectal mucosa (p = 1.59 × 10-6 and p = 6.95 × 10-9, respectively), whereas lincRNA-p21 showed lower expression in CRC tissues (p = 1.10 × 10-4). Logistic regression analysis results indicated that the expression of H19 was significantly lower in CRC patients with T2DM compared with CRC patients without T2DM (p = .032). H19 expression in CRC group without T2DM was significantly associated with hypertension (p = .040). Additionally, the area under the receiver operating characteristic curve of H19 was 0.672 of the group CRC with T2DM, which suggests that H19 could be a useful biomarker and predictive targets for diagnosis of T2DM in CRC patients.

Changes of breast cancer staging when AJCC prognostic staging manual is used: a retrospective analysis of a Chinese cohort.

BACKGROUND: This study aimed to investigate staging changes for Chinese breast cancer patients assessed by the 7th (anatomic) and 8th (prognostic) editions of the AJCC staging manual, and to explore the predictive factors for these changes. METHODS: Data of patients who received curative surgery for stage I-III breast cancer at Ningbo Medical Center Lihuili Eastern Hospital were retrospectively reviewed. The assessment of staging was according to the criteria of the 7th and 8th editions of the AJCC staging manual. Univariate and multivariate logistic regression analyses were performed to analyze the associations between staging changes and clinicopathological characteristics. RESULTS: Staging changes were found in 59.37% of patients and were more likely to be seen in stage IIIA (96.10%) and IIA (85.94%), then IIB (70.33%), IB (68.75%), followed by IA (36.17%) and IIIC (30.08%). In univariate analysis, staging changes were associated with tumor location, clinical tumor size, clinical axillary lymph node status and Ki67 index. However, multivariate analysis found that staging changes were significantly associated with tumor size >2 cm (odds ratio [OR] = 3.263, 95% confidence interval [95% CI], 2.638-4.036), lymph node involvement (OR = 2.261, 95% CI, 1.830-2.794) and high Ki-67 index (OR = 1.661, 95% CI 1.343-2.054). CONCLUSIONS: Our study demonstrated that there were marked staging changes when 2 different editions of the AJCC staging manual were used. Since prognostic biomarkers are available in routine clinical practice, the more recent staging manual should be followed to select better systemic therapy and give better outcomes for Chinese breast cancer patients.

Evidence from a large-scale meta-analysis indicates eczema reduces the incidence of glioma.

We investigated the relationship between eczema and the risk of primary glioma. Relevant studies were selected through electronic searches of PubMed and EMBASE. A meta-analysis of 12 case-control studies and one cohort study was performed. A fixed effect model was applied to analyze 13 studies consisting of 10,897 glioma cases and 56,081 controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the strength of the associations. The data demonstrate that eczema significantly reduces the risk of glioma (OR = 0.69, 95% CI = 0.61-0.78, P < 0.001). Additional studies with larger patient cohorts are required to validate our findings.
