Abstract
Background Increasing evidence emphasizes the potential relationship between diabetes and OAB (overactive bladder). However, large population epidemiology is still lacking. Methods This cross-sectional study included six cycle NHANES surveys, with a total of 23863 participants. Logistic regression models were constructed to analyze the association between diabetes mellitus, diabetes-related markers, and inflammatory biomarkers with OAB. Restricted cubic splines were used to analyze the non-linear associations. Mediating analysis was performed to test the effect of inflammatory biomarkers on the relationship between diabetes-related markers and OAB. Finally, machine learning models were applied to predict the relative importance and construct the best-fit model. Results Diabetes mellitus participants' OAB prevalence increased by 77% compared with non-diabetes. As the quartiles of diabetes-related markers increased, the odds of OAB monotonically increased in three models (all p for trend < 0.001). Glycohemoglobin exhibited a linear association with OAB (p for nonlinearity > 0.05). White blood cells significantly mediated the associations between diabetes-related markers (glycohemoglobin, fasting glucose, and insulin) with OAB, and the proportions were 7.23%, 8.08%, and 17.74%, respectively (all p < 0.0001). Neutrophils partly mediated the correlation between (glycohemoglobin, fasting glucose, and insulin) and OAB at 6.58%, 9.64%, and 17.93%, respectively (all p < 0.0001). Machine learning of the XGBoost model constructs the best fit model, and XGBoost predicts glycohemoglobin is the most important indicator on OAB. Conclusion Our research revealed diabetes mellitus and diabetes-related markers were remarkably associated with OAB, and systemic inflammation was an important mediator of this association.

Cytokine 2024; 173:156438. [PMID: 37976702 DOI: 10.1016/j.cyto.2023.156438] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 10/30/2023] [Accepted: 11/09/2023] [Indexed: 11/19/2023]
Abstract
OBJECTIVES To explore the role of allograft inflammatory factor-1 (AIF-1) both in diabetic rat bladder urothelium and in high-glucose-treated human urothelial cell line (SV-HUC-1). METHODS Inflammation and oxidative stress (OS) promote diabetic cystopathy (DCP), but the mechanisms are not fully understood. The expression level of AIF-1 in diabetic rat bladder urothelium and in the SV-HUC-1 cells treated with high glucose was detected using tissue immunofluorescence, immunohistochemistry and western blot assays. AIF-1 was knocked down and NF-κB was suppressed with the specific inhibitor BAY 11-7082 in high-glucose-treated SV-HUC-1 cells. RESULTS High-glucose condition induced AIF-1 upregulation in vivo and in vitro. The up-regulated AIF-1 induced the production of inflammatory factors IL-6 and TNF-α and elevation of ROS. Informatics analysis suggested that NF-κB pathway is implicated in DCP. Through knockdown of AIF-1, we confirmed that AIF-1 simulated NF-κB pathway by enhancing the phosphorylation of IκB (p-IκB) and promoting the translocation of NF-κB p65 from cytoplasm into nucleus. Additionally, High-glucose-induced inflammation in SV-HUC-1 cells was attenuated by the addition of NF-κB inhibitor. CONCLUSIONS This study provides novel information to understand the molecular regulation mechanisms of AIF-1 in DCP.

Abstract
Diabetes is a rapidly expanding epidemic projected to affect as many as 1 in 3 Americans by 2050. This disease is characterized by devastating complications brought about high glucose and metabolic derangement. The most common of these complications is diabetic bladder dysfunction (DBD) and estimates suggest that 50-80% of patients experience this disorder. Unfortunately, the Epidemiology of Diabetes Interventions and Complications Study suggests that strict glucose control does not decrease ones risk for incontinence, although it does decrease the risk of other complications such as retinopathy, nephropathy and neuropathy. Thus, there is a significant unmet need to better understand DBD in order to develop targeted therapies to alleviate patient suffering. Recently, the research community has come to understand that diabetes produces a systemic state of low-level inflammation known as meta-inflammation and attention has focused on a role for the sterile inflammation-inducing structure known as the NLRP3 inflammasome. In this review, we will examine the evidence that NLRP3 plays a central role in inducing DBD and driving its progression towards an underactive phenotype.

Bowel and Bladder Dysfunction Is Associated with Psychiatric Comorbidities and Functional Impairment in Pediatric Obsessive-Compulsive Disorder. J Child Adolesc Psychopharmacol 2022; 32:358-365.

Abstract
Objective: Neuropsychiatric disorders are common in children with bowel and bladder dysfunction (BBD), a syndrome associated with urinary frequency, urgency, holding, incontinence, and constipation. We evaluated BBD symptom severity in children and youth attending a tertiary care obsessive-compulsive disorder (OCD) clinic. Methods: Consecutive patients attending initial OCD assessments between 2016 and 2020 were invited to participate in a registry study. Diagnosis of OCD and comorbidities was established by structured clinical interview. OCD severity and impact were assessed with the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) and the Child Obsessive Compulsive Impact Scale (COIS-R; self-report), respectively. BBD symptoms were quantified with the Vancouver Symptom Score (VSS), a validated self-report measure. Results: One hundred twelve participants completed the VSS (mean age 13.5 ± 3.3, range 7-20). Based on a cutoff score of 11 corresponding to pediatric urologist-diagnosed BBD, 30.4% of participants screened positive, including more females than males (39.3% vs. 21.4%; p = 0.04). Daytime urinary incontinence was present in a greater proportion of participants with OCD forbidden thoughts (34.8% vs. 8.2%, p = 0.002), major depressive disorder (MDD; 38.5% vs. 6.8%, p = 0.001), and somatization disorder (60% vs. 9%, p = 0.001) compared with those without. A regression model including CY-BOCS, COIS-R, psychiatric comorbidities, medications, age, and gender explained 52.2% of the variance in VSS; COIS-R, tic disorder, and MDD were significant predictors. Conclusion: BBD symptoms are common and associated with high OCD-related impairment and psychiatric comorbidities. Standardized assessment may facilitate identification of BBD symptoms in this population and is critical to mitigating long-term physical and mental health impacts. Further studies are required to assess the relationship between BBD and OCD treatment outcomes.
