RESUMO

Introduction: The aim of this study was to compare the peri-operative outcomes, especially intraoperative surgeon workload and early post-operative pain, following midline ventral hernia repair by laparoscopic enhanced-view totally extraperitoneal (eTEP) approach and laparoscopic intraperitoneal onlay mesh plus (IPOM plus) approach. Patients and Methods: This single-centre randomised control trial study was conducted from January 2020 to June 2022. A total of 60 adult patients undergoing elective ventral hernia surgery with small- and medium-sized midline defects were included. Intraoperative surgeon workload and early post-operative pain were systematically recorded and analysed for each procedure. Results: Out of 30 patients assigned to each group, 29 patients underwent eTEP mesh repair and 27 patients underwent successful IPOM plus repair. The intraoperative surgeon's workload, especially mental demand, physical demand, task complexity and degree of difficulty as reported and felt by the operating surgeon, was significantly higher in the eTEP mesh repair group compared to IPOM plus group (P < 0.001) with comparable operating room distractions (P = 0.039). The mean overall post-operative pain score on post-operative day 1 was slightly less in eTEP mesh repair (4.28 ± 1.12) group compared to IPOM plus group (4.93 ± 1.17), which was statistically insignificant (P = 0.042). The eTEP group had significantly longer operative time and length of hospital stay compared to the IPOM plus group. Conclusion: Our study revealed significantly longer operative time, higher surgical workload and increased length of hospital stay in the eTEP group with comparable early post-operative pain in both groups, thus making eTEP mesh repair a more difficult and challenging procedure.

RESUMO

OBJECTIVE: This study aimed to examine the association of serum copeptin levels, a surrogate marker of arginine-vasopressin secretion with sense of coherence (SOC) among individuals with varying degrees of glucose intolerance. METHODS: The study was conducted in 120 age- and sex-matched individuals who were divided equally into three groups. Group A included individuals with normal glucose tolerance; group B, individuals with prediabetes (impaired glucose tolerance and/or impaired fasting glucose); and group C, individuals with newly detected diabetes mellitus (NDDM). SOC, perceived stress scale (PSS), copeptin, anthropometry, glycated hemoglobin, insulin, and salivary cortisol were measured in all study participants. RESULTS: The SOC score was found to be significantly lower in group C compared with group A (p < .001) and group B (p = .006). The PSS score was found to be significantly higher in group C compared with group A (p = .002). No significant difference was found between PSS scores of groups B and C (p = .25). Copeptin levels were found to be significantly higher in group C compared with group A (p = .016). Copeptin levels in group C did not differ significantly from those in group B (p = .056). There was a significant negative correlation between serum copeptin levels and SOC in the NDDM group C (r = 0.31, p = .048) and overall (r = 0.19, p = .037). In multiple regression analysis, SOC emerged as the variable with the strongest association with 2-hour postprandial plasma glucose and glycated hemoglobin. CONCLUSION: Individuals with NDDM displayed significantly higher serum copeptin levels that inversely correlated with SOC, a global measure of stress coping ability.

RESUMO

AIMS: Chronic stress is associated with increased risk of type 2 diabetes. Oxidative stress and inflammation are potential mediators of this risk. This study was conducted to investigate the association of oxidative stress and inflammatory markers with chronic stress and newly diagnosed type 2 diabetes. METHODS: Oxidative stress/antioxidant status (malondialdehyde [MDA], reduce glutathione [GSH], glutathione reductase [GR], glutathione peroxidase [GPx], catalase [CAT], superoxide dismutase [SOD]), inflammatory markers (highly sensitive C-reactive protein [hsCRP], adiponectin, leptin), chronic stress levels as assessed by stress scales-presumptive stressful life events scale (PSLES), perceived stress scale (PSS), sense of coherence (SOC) and stress biomarker-salivary cortisol in 125 subjects with newly detected diabetes mellitus (NDDM) were compared with an equal number of age and sex matched subjects with normal glucose tolerance (NGT). RESULTS: NDDM subjects as compared with NGT had significantly increased MDA (P < 0.001), hsCRP (P < 0.001), and leptin (P = 0.014) levels and increased GR (P = 0.043) and SOD (P < 0.001) activity along with decreased GSH (P < 0.001) and adiponectin (P < 0.001) levels. They also had significantly higher PSLES-LT and PSS and lower SOC scores along with elevated levels of 10:00 pm salivary cortisol and post dexamethasone salivary cortisol as compared with NGT. In stepwise logistic regression analysis, variables GSH (OR: 0.805), SOD (OR: 1.004), and adiponectin (OR: 0.771) along with PSLES-LT (OR: 1.007), PSS (OR: 1.147), SOC (OR: 0.667), salivary cortisol 10:00 pm (OR: 1.382), WC (OR: 1.087), and HOMA-IR (OR: 2.721) emerged as significant predictors of NDDM. CONCLUSION: The findings of this study indicate that chronic psychological stress and stress responses are associated significantly with inflammation and oxidative stress, which could act as mediating stress related risk factors for type 2 diabetes.

RESUMO

This study was carried to ascertain whether stress responses are associated with abnormalities in glucose tolerance, insulin sensitivity and pancreatic beta cell function and risk of type 2 Diabetes Mellitus. Salivary cortisol, a marker of hypothalamic-pituitary-adrenal (HPA) axis and salivary α-amylase, a marker of sympathetic nervous system (SNS) were compared in 125 subjects of newly detected diabetes mellitus (NDDM) and normal glucose tolerance (NGT) subjects who were diagnosed on the basis of oral glucose tolerance test (OGTT). Assessment of stress in them was done through stress scales - presumptive stressful life events scale (PSLES), perceived stress scale (PSS) and sense of coherence (SOC) and correlated with these and other stress response markers. Significantly higher 10 pm salivary cortisol and post dexamethasone salivary cortisol were found in NDDM subjects as compared to NGT. 10 pm salivary cortisol correlated significantly with fasting plasma glucose (FPG), 2 h plasma glucose (2h PG) and glycated hemoglobin (HbA1c) while post dex salivary cortisol correlated with 2h PG, HbA1c and salivary α-amylase with 2h PG. Stepwise logistic regression analysis showed that body mass index (OR: 1.840), SOC (OR: 0.688) and 10 pm salivary cortisol (OR: 1.427) were the strongest predictors of NDDM. The results of the present study indicate that NDDM subjects display significantly higher chronic stress and stress responses when compared to subjects with NGT. Chronic stress and endocrine stress responses are significantly associated with glucose intolerance, insulin resistance and diabetes mellitus.

RESUMO

BACKGROUND: Individuals with family history of diabetes carry nearly double the risk of diabetes than those without. However, the mechanism for this increased risk of diabetes in them is not fully understood. OBJECTIVE: To study fasting and postprandial triglyceride levels in individuals with normal glucose tolerance (NGT) who had family history of diabetes and to ascertain their association with insulin resistance. METHODS: Fasting triglyceride levels and HOMA-IR were compared in 671 NGT individuals with and without a family history of diabetes. A standardized fat challenge test was also done in one tenth of individuals of each group and postprandial triglyceride responses were compared between them. Association of HOMA-IR with fasting and postprandial triglyceride levels was ascertained through pearson's coefficient of correlation. RESULTS: Individuals with family history of diabetes had significantly higher HOMA-IR (P < 0.001) and significantly higher postprandial triglyceride AUC (P = 0.04) after standardized fat meal despite having similar fasting triglyceride levels (P = 0.51) as those without family history of diabetes. Fasting as well as postprandial triglyceride levels significantly correlated with HOMA-IR (r = 0.35, P < 0.001 and r = 0.39, P = 0.04) only in those with a positive family history of diabetes but not in those without. Triglyceride levels mediated the associations of BMI (Δ ß = -0.053) and waist circumference (Δ ß = -0.075) with HOMA-IR. CONCLUSION: Triglyceride levels, both in the fasting and the postprandial state are associated with insulin resistance in NGT individuals with a family history of diabetes but not in those without.

RESUMO

AIMS: The study was conducted to ascertain whether chronic stress and sense of coherence are associated with risk of type 2 diabetes mellitus. METHODS: Stress questionnaires - Presumptive Stressful Life Events Scale (PSLES), Perceived Stress Scale (PSS) and Sense of Coherence (SOC) - were administered to 500 Newly Detected Diabetes Mellitus (NDDM) cases and 500 Normal Glucose Tolerance (NGT) controls recruited following 75 g OGTT. Assessment of stress was completed before the diagnosis of diabetes was revealed to them. RESULTS: PSLES and PSS scores were significantly higher and SOC score was significantly lower in NDDM subjects compared to those with NGT. PSLES and PSS correlated positively with anthropometric parameters (waist circumference, BMI), glycemic parameters (FPG, 2 hPG, A1C) and HOMA-IR and inversely with HOMA-ß whereas SOC correlated inversely with glycemic parameters (FPG, 2 hPG, A1C) and HOMA-IR and positively with HOMA-ß. In stepwise logistic regression analysis, SOC emerged as the strongest independent predictor of diabetes (OR: 0.774) after HOMA-IR (OR: 1.621) and BMI (OR: 1.288). Other significant predictors included PSS (OR:1.153), PSLES-LT (OR: 1.005) and HOMA-ß (OR: 0.894). CONCLUSION: Chronic stress and low sense of coherence are associated with a higher risk of type 2 diabetes mellitus.

RESUMO

Paragangliomas are the neuroendocrine tumors which arise from the chromaffin cell. Tumors arising from the adrenal medulla are known as pheochromocytomas, while others originating from the extra-adrenal site are known as extra-adrenal paragangliomas. Paraganglioma can be multifocal which can arise synchronously or metachronously. Paragangliomas are less functionally active than the pheochromocytomas; they secrete noradrenaline and rarely dopamine, while adrenal pheochromocytomas secrete adrenaline or nor-adrenaline. Nonfunctional multifocal paragangliomas are very rare. We report a case of a 45-year-old female with multifocal nonfunctional paragangliomas of the retroperitoneum and urinarybladder which were surgically removed, and the diagnosis was confirmed on histopathology.
