Type 2 diabetes mellitus remission in sleeve gastrectomy patients: Role of enteroendocrine response and serum citrulline and I-FABP levels.

INTRODUCTION: This prospective cohort study examines the relationship between post-sleeve gastrectomy (SG) weight loss and serum citrulline, I-FABP levels, and the I-FABP/citrulline ratio in obese patients, alongside the correlation with type 2 diabetes mellitus (T2DM) remission. METHODS: 88 participants were enrolled, including 48 undergoing SG and 21 with T2DM. 40 healthy individuals served as controls. Preoperative and 1-year postoperative assessments included citrulline, I-FABP, glucose, insulin, HbA1c, and C peptide levels. RESULTS: Significant weight loss and T2DM remission (11/21) were observed post-SG. Preoperatively, patients had low citrulline and high I-FABP levels, which normalized postoperatively. A positive correlation was found between the I-FABP/citrulline ratio and weight, BMI, glucose, insulin, and C peptide levels. CONCLUSION: SG not only induces enterocyte dysfunction and mass recovery but also may facilitate T2DM remission and alleviate obesity-related effects on the enteroendocrine system. These findings highlight the potential beneficial effects of SG on enteroendocrine function in obese patients.

Neutrophil to C-reactive protein ratio: An estimating factor for intestinal ischemia before the surgery of incarcerated inguinal hernia.

Objective: An inguinal hernia may transform to an incarcerated hernia, which would require emergency surgery with increased morbidity and mortality. This study aims to analyze whether it is possible to predict intestinal ischemia in incarcerated hernia using complete blood count parameters and serum C-reactive protein (CRP). Methods: Medical records of 129 patients were used to analyze whether there is a correlation between intestinal ischemia and laboratory parameters. Receiver operating characteristics analysis and Youden index were used to determine cutoff values, sensitivity, and specificity. Results: Female patients, those with a femoral type hernia, and patients with additional diseases were found to be more prone to bowel resection. CRP, lymphocyte to CRP ratio (LCR), and neutrophil to CRP ratio (NCR) parameters were significant (AUC=0.914, p<0.001; AUC=0.901, p<0.001; and AUC=0.908, p<0.001, respectively). A value <0.45 for NCR has a sensitivity of 93.3% and specificity of 87.8%; a value >19 in CRP has a 90% sensitivity and 88.9% specificity. Conclusion: Decreased pre-operative NCR and LCR, and increased CRP levels can be used as a predictor for estimating intestinal ischemia.

Multiparametric MRI Evaluation of Developmental Venous Anomalies in the Brain: Association with Signal Changes on FLAIR in Patients with Multiple Sclerosis.

BACKGROUND: Developmental venous anomalies (DVAs) can be determined on magnetic resonance imaging (MRI), and they may be associated with multiple sclerosis (MS) lesions. PURPOSE: The objective was to evaluate the MRI findings of DVAs in the brain, to compare the prevalence of them between MS patients and control subjects, and to investigate the correlation of DVA-associated fluid-attenuated inversion recovery (FLAIR) hyperintensities and MRI-derived parameters between MS patients and control subjects having DVA. METHODS: Total 160 patients with a mean age of 45 ± 16 years who underwent multiparametric MRI including susceptibility-weighted imaging (SWI), diffusion-weighted imaging, 3D FLAIR, and contrast-enhanced imaging were included in this retrospective study. First, the presence of DVA was compared between the MS and control groups using the Chi-square test. Then, among the subjects having DVA, age, gender, and MRI-derived parameters such as the signal increase of DVA on FLAIR, location, and drainage of DVA were compared between the MS and control groups using Chi-square test. RESULTS: The presence of DVA did not differ between the MS and control groups (P = 0.828). Signal increase around DVA on FLAIR (P = 0.03) and the age of less than 45 years demonstrated a significant correlation with MS group (P = 0.022). CONCLUSION: In our study, DVAs were effectively detected using SWI and 3D contrast-enhanced T1-weighted imaging on MRI. The signal increase of DVA was better revealed on 3D FLAIR on MRI, and it was the only significant MRI-derived parameter in patients with MS.

The disrupted connection between cerebral hemispheres in schizophrenia patients: a diffusion tensor imaging study.

AIM: In schizophrenia, the disruption of the communication between two brain hemispheres has not been shown clearly in the anatomical aspect despite other studies with different modalities suggested so. In this study, the structural integrity and the variables affecting the structural integrity of the corpus callosum, which is the main connection between two hemispheres, was investigated via diffusion tensor imaging (DTI). METHODS: The participants were evaluated by SCID-I and symptoms of the patients were assessed with PANSS. DT images of 25 schizophrenia patients and 17 healthy volunteers were acquired via 1.5 T MR. Fractioned Anisotropy (FA) values of two groups, measured on the DT images, were compared. RESULTS: It was found that fractioned anisotropy (FA) values were lower in the genu of the patients than the healthy controls; however, there was no difference between the FA values of the patients and the controls in the splenium. Moreover, a significant negative correlation between the splenium FA values and the antipsychotic medication doses; and a trend level negative correlation of splenium FA and PANSS scores were found. CONCLUSION: Corpus callosum is the most important structure that connects two frontal lobes. The hypothesis that posits the fundamental role of the disconnection of frontal lobes in schizophrenia is supported by the findings of this study.
