Abstract
BACKGROUND Fast acting insulin analogues are known to improve arterial stiffness. The combination of metformin with insulin represents a widely used therapeutic strategy in diabetes. We hypothesized that insulin treatment in patients with type 2 diabetes (T2D) with long-acting, fast-acting or basal bolus insulin as an add-on to metformin would provide additional improvement of arterial stiffness. METHODS The INSUlin Regimens and VASCular Functions (INSUVASC) study is a pilot, randomized, open label three-arms study that included 42 patients with type 2 diabetes (T2D) in primary prevention, after a failure to oral antidiabetic agents. Arterial stiffness measurements were performed at fasting and after a standardized breakfast. During the first visit (V1) pre-randomization, participants took only metformin to perform the tests. The same tests were repeated after 4 weeks of insulin treatment during the second visit (V2). RESULTS Data were available for final analysis in 40 patients, with a mean age of 53.6±9.7 years and a mean duration of diabetes of 10.6±5.6 years. Twenty-one were females (52.5%), hypertension and dyslipidemia were present in 18 (45%) and 17 patients (42.5%), respectively. After insulin treatment, the metabolic control was associated to a decrease in oxidative stress and improvement of endothelial functions, with a post prandial diastole duration increased and a decrease of the peripheral arterial stiffness, with a better post prandial pulse pressure ratio and ejection duration after insulin. In hypertensive patients, insulin treatment provided positive effects by decreasing the pulse wave velocity and improving reflection time. CONCLUSIONS A short time treatment by insulin in addition to metformin improved myocardial perfusion. Moreover, insulin treatment in hypertensive patients provides a better hemodynamic profile in large arteries.

Abstract
BACKGROUND Physical activity (PA) is an established modifiable factor for the prevention of cardiovascular disease. Our objective was to assess the association of PA with mortality rates in a national sample of patients with diabetes. METHODS We analyzed a nationally representative sample from The National Health and Nutrition Examination Survey (NHANES, periods 2003-2004 and 2005-2006) that used PA Monitors. Individuals were matched for BMI, number of steps/per day and age. Three groups were created: subjects with less than 5000/steps per day (low), 5000-7500/steps per day (moderate) and more than 7500/steps per day (high levels of physical activity). All-cause mortality was ascertained through December 2015. RESULTS A sample of 3072 individuals (1018 with diabetes) was analyzed. Patients with diabetes had 30% increased risk of mortality of all causes (RR: 1.298, 95% CI [1.162-1.451], P<0.001), higher levels of PA (>7500 steps/day) provided similar relative risk for subjects with diabetes compared to their controls (RR:1.256 [95% CI 0.910-1.732]). In a Poisson model adjusted for sex, history of previous cardiovascular event or cancer, ethnicity, Hb1ac, SBP, and total cholesterol to HDL ratio, patients with diabetes and moderate or high PA had an associated 44% to 80% lower risk of all-cause mortality compared to those with low PA. CONCLUSIONS The subgroup of patients with diabetes and high PA had no excess of mortality compared to the general population. PA can reduce the gap for all-cause mortality, used as an index of cardiovascular fitness and a clinical tool for the assessment of mortality risk.

Abstract
INTRODUCTION Glucagon-like peptide 1 receptor agonists (GLP1-RA) and sodium-glucose cotransporter-2 inhibitors (SGLT2i) were individually proven to reduce major adverse cardiovascular events (MACE) in type 2 diabetes mellitus (T2DM) patients, but the relative magnitude of benefits from these two drug classes is debated. We aimed to review current available data on GLP1-RA and SGLT2i in T2DM patients and compare their efficacy and safety in this population. EVIDENCE ACQUISITION We systematically searched MEDLINE/PubMed, the Cochrane Library, Google Scholar, Embase, www.tctmd.com, www.clinicaltrials.gov, www.clinicaltrialresults.org, from inception to September 17, 2020 for randomized controlled trials (RCTs) comparing the effects of GLP1-RA vs SGLT2i vs optimal medical therapy (OMT) in adult T2DM patients. Three authors independently screened references and extracted data using a predefined data collection form. Outcomes were analyzed using an indirect comparison meta-analysis of aggregate study-level data. The primary combined efficacy outcome comprised cardiovascular death, nonfatal myocardial infarction (MI), or nonfatal stroke. Secondary efficacy outcomes included all-cause mortality, cardiovascular mortality, non-fatal MI, non-fatal stroke, heart failure hospitalizations (HFH), and worsening renal function (WRF). EVIDENCE SYNTHESIS 11 RCTs enrolling a total of 98572 patients were included; 56004 (57%) patients were derived from GLP1-RA RCTs and 42568 (43%) from SGLT2i RCTs. At a median follow-up of 3.0±1.3 years, compared with OMT, both GLP1-RA and SGLT2i similarly reduced the rate of the composite primary outcome (risk ratio [RR] 0.88; 95% confidence interval [95%CI] 0.83-0.93 and RR 0.88, 95%CI 0.82-0.95, respectively) with no difference between the drug classes (RR 1.00, 95%CI 0.92-1.10). Both classes similarly reduced MI rate, cardiovascular and all-cause mortality compared with OMT; stroke reduction was only observed with GLP1-RA with no difference in the indirect comparison with SGLT2i; conversely, only SGLT2i were effective in preventing HFH. Both GLP1-RA and SGLT2i were protective against WRF, with a major efficacy of SGLT2i in the indirect comparison. CONCLUSIONS This meta-analysis report that GLP1-RA and SGLT2i reduced with a similar efficacy not only MACE as MI, but also cardiovascular mortality and all-cause mortality at a median 3 years follow-up. SGLT2i were more protective in HFH and WRF than GLP1RA. These new data highlight the efficacy of SGLT2i not only in HF and chronic kidney disease (CKD) but also in ischemic heart diseases (IHD), with a homogeneity among the class, whereas the results observed with GLP1-RA are heterogenous. These findings will help clinical's decisions to optimize therapeutic strategies for diabetic patients.

Abstract
BACKGROUND AND AIMS Studies of dipeptidyl peptidase inhibitors (DPP4is) report heterogeneous effects on cardiovascular targets in type 2 diabetes. This study aimed to investigate, in patients with impaired glucose tolerance (IGT), whether saxagliptin, a DPP4i, had beneficial cardiovascular effects at fasting and during the post-prandial state. METHODS AND RESULTS In this randomized, placebo-controlled, double-blind, single-center pilot exploratory study, we included obese individuals with IGT. Twenty-four individuals (BMI 36.8 ± 4.8 kg/m2) were randomized to receive for 12 weeks either saxagliptin 5 mg a day or placebo. They were explored before and after a standardized breakfast for biological markers; microcirculatory blood flow at baseline and after transcutaneous administration of acetylcholine (Periflux System 5000® PERIMED); post-occlusive digital reactive hyperhemia (Endopat2000®); pulse wave velocity, augmentation index, central pulse pressure and subendocardial viability ratio (Sphygmocor®); cardiac hemodynamic parameters and cardiovascular autonomic nervous system activity (Task force monitor®). The results of all the investigations were similar after breakfast in the two groups at Visit 1 (acute post-prandial effects, after the first tablet) and Visit 2 (long-term post-prandial effects), and at fasting at Visit 1 and 2 (long-term effects, after 12 weeks of treatment). Only at Visit 2 the decrease in cardiac vagal activity occurring after breakfast was more sustained in the saxagliptin group than in the placebo group (interaction between treatment and time effect: p = 0.016). CONCLUSION In obese patients with IGT, the effects of saxagliptin on the large set of cardiovascular parameters measured are neutral, except for a more marked post-prandial depression of vagal activity.

Abstract
An increase in employment rate was observed among individuals who underwent bariatric surgery. This study assessed the relationship between employment rate and weight loss, deprivation, and Bariatric Analysis and Reporting Outcome System (BAROS) scores after bariatric surgery in a deprived area. This retrospective study evaluated the employment rate at a mean period of 2.3±0.1 years after bariatric surgery among 133 individuals. The Evaluation of Deprivation and Inequalities in Health Examination Centers (EPICES score), satisfaction scale, and BAROS (self-esteem, physical activity, social life, work conditions, and sexual activity) questionnaires were used. The mean age of the participants was 45 (range: 19–67) years. Approximately 88% were women. The initial mean body mass index (BMI) was 42.7 kg/m2, and about 88% of the participants underwent sleeve gastrectomy. The mean decrease in BMI was 12 ± 0.5 kg/m2. The mean EPICES score (N<30), BAROS, and satisfaction scale (range: 1–5) scores were 31.9±18, 1.3±1.1, and 4.27±1.19, respectively. After surgery, 19 participants obtained a job. However, three were unemployed. Based on a multivariate analysis, employed and unemployed participants (77 vs 52) before surgery had a lower initial BMI and better BAROS and satisfaction scale scores. After surgery, there was no difference between participants who obtained a new job and those still did not have a job in terms of questionnaire responses. Obtaining a new job was not associated with BMI, sex, or age differences. However, there was a positive correlation between social life score and weight loss. Bariatric surgery increased an individual’s chance of finding a job independently of deprivation status. Participants with a pre-operative job had a better perception of satisfaction and BAROS scores. Moreover, social isolation was correlated with unsuccessful weight loss.

Abstract
The continuous progress in cardiovascular (CV) risk prevention strategies has led to an impressive reduction in mortality and recurrent ischemic events in patients with coronary artery disease (CAD). However, the control of several CV risk factors remains suboptimal in many CAD patients, with a high rate of recurrent events, underlying the need for more new prevention strategies. The GAPS-I (GLP1 analogues, Antithrombotic agents, PCSK9 inhibitors, SGLT2 inhibitors and Immunomodulators) strategy offers a promising potential in patients with a high-residual CV risk, who are frequently encountered in daily practice, by offering an individualised and structured approach to addressing their individual risk factors. The current review summarises the evidence to date on each of its components, with respect to clinical outcomes and economic feasibility. The current evidence points to an efficacy of GAPS-I in reducing MACE and mortality, without a compromise on safety, albeit with the need for longer follow-up data. Key Points: - Secondary prevention remains suboptimal in many CAD patients, highlighting the need for innovative prevention strategies. - The present review discusses the current evidence on efficacy of the GAPS-I strategy in reducing MACE and mortality in patients with CAD. - The GAPS-I strategy, if widely adopted, provides a promising potential to assist cardiologists in managing patients at a heightened risk for further CV events.

Abstract
Background/Aims Self-reported lactose intolerance (LI) is frequent in patients with functional bowel disorders (FBD) that could be interpreted as irritable bowel syndrome (IBS). The present study aims to characterize the responses of patients with FBD, without small intestinal bacterial overgrowth (SIBO), and LI, in terms of lactose malabsorption (LM) and lactose sensitivity (LS) according to psychological and clinical features. Methods One hundred and fifty-eight consecutive FBD outpatients with LI, and no SIBO, were classified according to the Rome III questionnaire and filled Beck Depression Inventory, and State and Trait Anxiety questionnaires. They underwent a lactose tolerance test in which glycemia during 60 minutes and digestive symptoms for 3 hours were recorded. Results Abnormal lactose tolerance tests were found in 110 patients (70%), 44 (28%) with LM, 96 (61%) with LS, and 30 (19%) having both LM and LS. LM patients had a higher frequency of functional diarrhea (P = 0.040) and a lower frequency of dysphagia (P = 0.031). LS patients had a higher depression score (P = 0.007), higher frequency of globus (P = 0.042), irritable bowel syndrome (IBS) (P = 0.027) and mixed IBS (P = 0.049), and lower frequency of abdominal pain (P = 0.040). LS was significantly associated with a higher depression score (P = 0.002), and a higher frequency of globus (P = 0.046). Conclusions Thirty percent of LI patients have normal lactose absorption and normal LS. In the other 70% of patients, LI could be associated with LM and/or LS.

BACKGROUND AND AIMS Dipeptidyl-peptidase inhibitors might be useful in type 2 diabetes prevention. ACCES (ACute and Chronic Effects of Saxagliptin) was a randomized, placebo-controlled, double-blind, controlled phase 2, pilot study aiming to examine in obese patients with impaired glucose tolerance (IGT) the acute effects and the effects after 12 weeks of treatment by saxagliptin on glucose levels at fasting and postprandially after a standard breakfast, and on glucose tolerance. METHODS AND RESULTS We included 24 obese patients with IGT. Patients were randomized to receive saxagliptin 5 mg or placebo in the morning. The treatment was taken on Visit 1 before breakfast, then continued for 12 weeks. Biochemical measurements were performed before, one, two and three hours after a standard breakfast including 75 g of carbohydrates, during Visit 1 and Visit 2 (12 weeks). Glucose variability (GV) was evaluated at Visit 1 from 24-h continuous glucose monitoring including the breakfast. A second OGTT was performed at Visit 3 (3-5 days after Visit 2). Compared with placebo-treated patients, saxagliptin-treated patients had lower 1 h and 2 h post-meal plasma glucose levels at Visit 1 and similar changes at Visit 2 (p < 0.01 to p < 0.004), with lower GV indexes after breakfast at Visit 1. At Visit 3, all patients but one in saxagliptin group and only 4 patients in placebo group turned to normal glucose tolerance. Lower glucose response to breakfast at Visit 1 was predictive of recovery of glucose tolerance. CONCLUSION Saxagliptin has metabolically beneficial effects in glucose-intolerant obese patients by significantly lowering postprandial blood glucose levels.

Abstract
Background To investigate whether chronic adherence to the French Nutrition and Health Program (PNNS) guidelines was associated with better cardiovascular health. Methods A study nested within the SU.VI.MAX2 cohort was conducted on participants without cardiovascular risk factors. Long-term adherence to the PNNS guidelines was estimated using validated dietary scores from 2007 and 2012. Individuals who did (PNNS+) and did not (PNNS−) continuously adhere to the PNNS guidelines were included. Applanation tonometry, impedance cardiography, laser doppler flowmetry, heart rate, heart rate variability, endothelial function was used for the assessment of cardiovascular health. Results A total of 49 subjects (mean age 65.4 ± 5.6 years, 75.5% women) had been included. Those in the PNNS+ group (n=26) were older, had a higher BMI and fat mass than those in the PNNS− group, both groups had similar metabolic parameters. After adjusting for sex, age, and BMI, PNNS+ subjects were found to have a lower heart rate (60.2 ± 8.0 vs 64.3 ± 8.4 beats/min, p=0.042), a lower heart rate × systolic blood pressure product (7166 ± 1323 vs 7788 ± 1680 beats× mmHg/min, p = 0.009), a longer diastole duration (66.7 ± 3.1% vs 64.6 ± 4.1% of the cardiac cycle duration, p=0.049), and a shorter tension–time index (2145 ± 489 vs 2307 ± 428 ms * mmHg, p=0.018) compared to the PNNS− group. Conclusion Long-term adherence to the PNNS guidelines had a favorable impact on heart rate, diastole duration, and myocardial oxygen consumption. Clinical Trial Registration number NCT01579409.

Abstract
BACKGROUND/AIMS The aim of the present study is to evaluate if the intensity of the cardinal symptoms of functional bowel disorders could be used to identify homogenous groups of patients defined by the Rome criteria. METHOD In this observational study, 1,729 consecutive outpatients (73% females) filled out the Rome III questionnaire and 10-point Likert scales for constipation, diarrhea, bloating (BL)/distension, abdominal pain (AP) during the week before the medical consultation. A Gaussian mixture model was used for clustering the patients according to the intensity of symptoms without a priori information, and a classification tree was constructed from this clustering. Data were analyzed using analysis of variance and logistic regression analysis. RESULTS According to the intensity of symptoms, the patients are divided into 8 groups named according to their main symptomatology: "painful constipation" (PFC), "mild pain constipation" (MPC), "painful diarrhea" (PFD), "mild pain diarrhea" (MPD), "mixed transit" (MT), "BL," "AP," and "nonspecific" (NS). The study of the relationship between the Rome III classification and this new grouping shows that irritable bowel syndrome (IBS)-constipation is associated with PFC, IBS-diarrhea with PFD and MPD, SII-mixed with MT, SII-unspecified with BL, functional constipation with PFC and MPC, functional diarrhea with MPD and NS, BL with "BL" and NS, nonspecific functional bowel disorders (FBD) with NS, and functional AP with "BL" and AP (p < 0.01 for all associations). CONCLUSION A symptom intensity-based classification of FBD patients could simplify clinical phenotype, give homogeneous groups of patients, and could eventually be used by nongastroenterologists and in clinical research.

Abstract
Background/Aims Discordant data are found in the literature for the relationships between total and segmental colonic transit time (CTT) and demographic parameters. The aim of this study is to examine the influence of age, and body mass index (BMI) on total and segmental CTT in constipated subjects. Methods We included 354 constipated patients on this cross-sectional study. According to the Rome III criteria, patients were classified as having irritable bowel syndrome with constipation, or functional constipation. All patients filled the Bristol stool form, and reported the severity of constipation, bloating, and abdominal pain on a 10-point Likert scale. Total and segmental CTT were measured using radiopaque markers. Results Females were 84% of patients, with a mean age of 46.0 ± 15.9 years. The association between total and segmental CTT with age and BMI was significant after adjustment for gender, clinical phenotype, the presence of defecation disorders, and abdominal pain or bloating intensity despite the severity of symptoms, and the frequency of defecation disorders were higher in irritable bowel syndrome with constipation than in functional constipation patients. By comparison with subjects less than 30 years, rectosigmoid transit time (RSTT) was lower in patients between 30 and 60 years. Age was negatively associated with RSTT (P = 0.004). By comparison with patients with normal BMI, RSTT and total CTT were lower in patients of the overweight group. BMI was negatively associated with RSTT (P < 0.001). The severity of constipation was correlated with total (P < 0.001), right (P = 0.002), and left CTT (P = 0.049). Conclusion Age and BMI are both associated with RSTT in constipated patients.

Abstract
Patients with ketosis prone diabetes have been reported primarily in Africans and African Americans. At presentation, both insulin secretion and insulin action are impaired in ketosis prone diabetes patients. Fulminant diabetes is a subtype of type 1 diabetes reported mainly in the Asian populations characterized by diabetic ketosis or ketoacidosis occurring soon after the onset of hyperglycemic symptoms with inappropriately low HbA1c (< 8.5%). We report here the first case of a ketosis prone diabetes presenting as fulminant diabetes.

Abstract
BACKGROUND AND AIMS Changes in appetite are a frequent complaint in patients with functional gastrointestinal disorders (FGIDs). The aims of this study are to evaluate whether the changes in appetite are associated with specific FGIDs and to explore associations of these changes with symptoms of anxiety or depression. METHODS This study included 1009 consecutive FGID patients (71% female), aged 48.9 years who all filled out a Rome III questionnaire for the evaluation of FGIDs, submitted to a psychological evaluation of symptoms of anxiety, and completed the Beck Depression Inventory questionnaire. The patients were classified according to their appetite change using a 7-point grading scale and split into three groups: those with appetite loss, those with no change in appetite, and those with increased appetite. RESULTS Among the 1009, 496 patients (49%) reported a change in appetite, of which 332 (33%) patients reported a decrease in appetite and 164 (16%) patients reported an increase in appetite. Appetite was not affected in 51% of patients. Changes in appetite depended on gender, body mass index and psychometric evaluation scores. Increased appetite did not have specific FGIDs associations, while decreased appetite was associated with esophageal, gastroduodenal, bowel, and anorectal symptoms. The presence of depressive symptoms was also a predictor for the majority of FGIDs in decreased appetite, while anxiety trait was significant for globus and dysphagia. CONCLUSIONS Decreased appetite was associated with FGIDs, especially in the presence of depressive symptoms. A reduced appetite would help to predict psychological disorders associated with FGIDs. FINANCIAL DISCLOSURE None declared.

Abstract
BACKGROUND A single insulin injection was shown to improve microcirculatory blood flow. Our aim was to examine the effects of 4weeks of insulin therapy by three randomly assigned insulin analog regimens (Detemir, Aspart, and their combination) on cutaneous blood flow (CBF) and microcirculatory endothelial function as an add-on to metformin in type 2 diabetic patients poorly controlled on oral antidiabetic treatment. METHODS Fourty-two type 2 diabetic patients with no history of cardiovascular disease in secondary failure to oral antidiabetic agents had CBF measurements before and after acetylcholine (Ach) iontophoretic administration. CBF measurements were performed at fasting and after a standardized breakfast during the post-prandial period. Before randomization (Visit 1, V1) during the tests, participants took only metformin. The same tests were repeated after 4weeks of insulin treatment (Visit 2, V2). RESULTS Thirty-four patients had good quality recordings for both visits. During V1, CBF and CBF response to Ach increased in the post-prandial period. After 4weeks of insulin treatment, metabolic parameters improved. Compared to V1, CBF at fasting did not increase at V2 but there was an improvement in endothelial function at fasting after Ach iontophoresis, without difference across insulin regimens. Oxidative stress markers were not modified, and E-selectin and vascular cell adhesion molecule 1 levels decreased after insulin treatment, without differences between insulin groups. CONCLUSIONS A strategy of improving glycemic control for 4weeks with insulin analogs improves microcirculatory endothelial reactivity and reduces endothelial biomarkers at fasting, whatever the insulin regimen used. Insulin therapy associated to metformin is able to improve fasting microvascular endothelial function even before complete metabolic control.

Abstract
BACKGROUND Rosacea fulminans (RF) is a severe form of facial dermatosis presenting with a sudden onset of numerous facial pustules, papules, and erythema. During pregnancy its treatment may be difficult and can have an impact on obstetrical outcomes. CASE A 37-year-old woman during the 37th week of her fourth pregnancy presented RF that was associated with ocular manifestations. The usual treatment with isotretinoin was contraindicated during pregnancy and the patient started an alternative treatment with prednisone and azithromycin. After delivery at 38 weeks of gestational age, there was a significant improvement. CONCLUSION RE is a severe dermatological disease with unknown etiology and with a rapid improvement in the immediate postpartum period.

Abstract
Spontaneous hemoperitoneum is defined as bleeding within the peritoneal cavity of non-traumatic and non-iatrogenic etiology. It is a rare and life-threatening condition during pregnancy. Spontaneous hemoperitoneum is considered idiopathic when the source of bleeding is not detected during the exploratory laparotomy. The authors report two cases of spontaneous hemoperitoneum during pregnancy with sudden onset of abdominal pain during the third trimester of their pregnancy. Cesarean section was performed for fetal distress. In both cases, hemoperitoneum with a large quantity of blood was found, but the source of bleeding could not be identified during surgical exploration.

Abstract
BACKGROUND Obesity is frequently associated to many functional gastrointestinal disorders. The aim of the present study was to assess the prevalence of functional gastrointestinal disorders in obese patients, according to their body mass index and their recruitment source. METHODS Five hundred ninety-six obese patients (body mass index (BMI) > 30) filled out a standard questionnaire in order to evaluate the presence of functional gastrointestinal disorders. They were divided into four groups according to the Rome III criteria and their BMI: OF, obese patients from functional gastrointestinal disorder (FGID) enrollment; OO, obese patients from obesity management enrollment; MF, morbid obesity patients from FGID enrollment; and MO, morbid obesity patients from obesity management enrollment. Data analysis was performed using multivariate logistic regression. RESULTS Out of the 596 obese patients included in the present study, 183 (33 %) were complaining of FGIDs, while 413 (67 %) were consulting for obesity management. Compared to the OF group, the OO patients had a higher prevalence of females (P = 0.008) and a younger age (P < 0.001). Clinically, they reported a lower incidence of regurgitation (P = 0.044), of chest pain (P = 0.004), of irritable bowel syndrome (IBS; P = 0.035), and of functional diarrhea (P = 0.030). Compared to the MF group, the MO patients had an older age (P = 0.001), a higher BMI (P = 0.013), and clinically by a high frequency of functional dyspepsia (P = 0.006). There were symptoms that had similar prevalence in all groups (OF, OO, MF, MO) such as epigastric pain, postprandial distress, constipation, diarrhea, bloating, abdominal pain soiling, or nonspecific anorectal disorders. CONCLUSIONS This study has shown that the recruitment source accounted for marked and specific differences in the prevalence of functional gastrointestinal disorders in obesity and morbid obesity. Symptoms with similar prevalence in all groups should be systematically detected in all patients.

Abstract
OBJECTIVE The primary aim of our study was to determine the prevalence of macroscopic deciduosis Found randomly in Cesarean sections and the secondary objective to determine the association with any obstetrical complications or adverse effects. METHODS This is a unicenter prospective study from 01/08/2011 to 01/02/2014. During the study period 307 consecutive Cesarean sections were performed with 31 biopsy proven cases of macroscopic deciduosis in the ovary, uterine and fallopian tube serosa. RESULTS The mean age of the patients was 31.2 ± 5.4 years (range 13-43), the mean Body Mass Index was 26.3 ± 5.8 (range 15-48)kg/m(2), the mean term of Cesarean was 270 ± 25 days, and the mean fetal weight was 3094 ± 809 g. The majority of patients were Caucasian (n=175, 57.0%). Patients with deciduosis had a greater BMI (28.4 ± 5.3 kg/m(2) vs 25.7 ± 5.8 kg/m(2), p<0.05). The presence of pain was more frequent in the deciduosis group (10.1%, OR 5.78, 95%, CI [2.41-13.87], p<0.001). CONCLUSION Deciduosis is a benign lesion during pregnancy that is not correlated with obstetrical complications. Our study has shown that this physiological phenomenon is more frequent that originally thought, being present in 10% of the Cesarean sections, and is associated with abdominal pain during pregnancy.

Abstract
BACKGROUND AND AIMS Arterial stiffness, a measure of macrovascular damage predictive of poor cardio-vascular outcomes, is strongly related to age and hypertension (HT). In diabetic patients peripheral neuropathy (PN) has been found to be associated with increased arterial stiffness, which might be due to the concomitant presence of HT. The aim of this study was to examine in type-2 diabetic patients, the relationship between arterial stiffness and presence or absence of PN and HT separately. METHODS AND RESULTS Arterial stiffness was measured with the gold standard carotid-femoral pulse wave velocity (PWV) in 447 type-2 diabetic subjects of whom 66% were hypertensive, 53% had PN, and 40% had both. Patients with PN were older, more often hypertensive and had higher PWV than those free of PN. Patients were separated according to the presence or absence of PN and HT. PWV values above the 90th percentile age- and blood pressure-adjusted reference range (PWV+) were different across these groups (p < 0.005) with the following respective prevalences: 27.2%, 53.4%, 33.3% and 30.6%. Only PWV+ was significantly associated with PN and hypertension in the interaction analysis. CONCLUSION Well controlled hypertensive patients did not have elevated arterial stiffness compared to normotensive patients. This might be due to anti-hypertensive treatment although our study design does not allow us to confirm it. A strong association between PN and arterial stiffness was only present in normotensive patients, suggesting that normotensive type 2 diabetic patients with PN and elevated arterial stiffness should be carefully managed to prevent future macrovascular complications.

Abstract
OBJECTIVE The contribution of postprandial glycemia (PPG) to hyperglycemia has been shown to decrease as HbA1c increased in type 2 diabetic patients. This study aimed at examining, in a series of overweight/obese patients without known glycemic disorder, the contribution of PPG to a "relative" hyperglycemia (glucose values≥5.5 mmol/L) and the presence of glycemic variability according to HbA1c levels. METHODS Seventy overweight/obese inpatients (body mass index 35.2±6.8 kg/m2) without known glycemic disorder were included. Participants were classified according to an oral glucose tolerance test (according to the American Diabetes Association criteria) as patients with normoglycemia (n=33), with intermediate hyperglycemia (n=24) or diabetes (n=13). They were separated into HbA1c quartiles (Q1 to Q4). A 24 hour continuous glucose monitoring was used under a 1800 kcal diet and minimal physical activity. We assessed PPG contribution (3 hour period after each meal) to the "relative" 24 hour hyperglycemia (glucose values ≥5.5 mmol/L); the remaining time was considered as the fasting/post-absorptive period. RESULTS HbA1c range was from 5.1% to 7.4% (32 to 57 mmol/mmol). From the lowest to the highest HbA1c quartile, the area under the curve (AUC) for the "relative" hyperglycemia presented a 17-fold increase for the fasting/post-absorptive (p<0.001) period and a 7-fold increase postprandially (p<0.001). The percent of PPG contribution to the "relative" hyperglycemia was calculated with the following formula [100×(postprandial 3 hour AUC-3 h AUC for a constant 5.5 mmol/L glycemia)/(total 24 h AUC-24 h AUC for constant 5. 5 mmol/L glycemia)] and decreased from Q1 to Q4 of HbA1c (81.2%, 66%, 65.8%, 57%; p<0.001). Increasing HbA1c quartiles were associated with higher daily mean blood glucose level (p<0.001) and higher levels of daily glucose variability indices, including mean amplitude of glycemic excursions (p<0.01). CONCLUSIONS In overweight/obese patients, HbA1c was associated with lower PPG contribution to "relative" hyperglycemia and greater glycemic variability. The present findings support the importance of postprandial period in glycemic exposure even before the appearance of diabetes.

Abstract
BACKGROUND The efficacy and safety of bariatric surgery have been poorly studied in patients affected with HIV. Although sleeve gastrectomy (SG) is the most widely used procedure in many countries, most of the published literature reported results with the gastric bypass (GBP) procedure on morbidly obese HIV patients. METHODS We have evaluated retrospectively, in eight consecutive patients who underwent a SG, its effect in weight loss and its impact on the treatment and on the markers of HIV infection. RESULTS Seven out of eight patients were females. The mean age was 46 years, with a median preoperative BMI of 42 kg/m(2). The mean duration of HIV infection and CD4 cell count were 13.4 years and 457 cells/mm(3), respectively. The mean weight loss was 37 kg in 20 months, the excess BMI loss was 80.8 ± 30.9 %, and the excess weight loss is 81.5 ± 28.9 % with one minor complication. CD4 counts were unchanged. Three patients had therapy modifications that were unrelated to bariatric surgery. Two patients had a therapeutic drug monitoring before and after the intervention. Plasma concentrations remained in therapeutic levels after the SG. Most comorbidities disappeared postoperatively, decreasing the cardiovascular risk. CONCLUSIONS The sleeve gastrectomy was safe and effective with no consequences on CD4 counts and viral load in HIV-affected obese patients. It should be considered as a part of the treatment in morbidly obese HIV patients.

Abstract
The kallikrein-kinin system has been suggested to participate in the control of glucose metabolism. Its role and the role of angiotensin-I-converting enzyme, a major kinin-inactivating enzyme, are however the subject of debate. We have evaluated the consequence of deficiency in tissue kallikrein (TK), the main kinin-forming enzyme, on the development of insulin resistance and diabetes in mice and man. Mice with inactivation of the TK gene were fed a high-fat diet (HFD) for 3 months, or crossed with obese, leptin-deficient (ob/ob) mice to generate double ob/ob-TK-deficient mutants. In man, a loss-of-function polymorphism of the TK gene (R53H) was studied in a large general population cohort tested for insulin resistance, the DESIR study (4843 participants, 9 year follow-up). Mice deficient in TK gained less weight on the HFD than their WT littermates. Fasting glucose level was increased and responses to glucose (GTT) and insulin (ITT) tolerance tests were altered at 10 and 16 weeks on the HFD compared with standard on the diet, but TK deficiency had no influence on these parameters. Likewise, ob-TK⁻/⁻ mice had similar GTT and ITT responses to those of ob-TK⁺/⁺ mice. TK deficiency had no effect on blood pressure in either model. In humans, changes over time in BMI, fasting plasma glucose, insulinemia, and blood pressure were not influenced by the defective 53H-coding TK allele. The incidence of diabetes was not influenced by this allele. These data do not support a role for the TK-kinin system, protective or deleterious, in the development of insulin resistance and diabetes.

Abstract
OBJECTIVE Our purpose was to evaluate the efficacy and safety of sleeve gastrectomy (SG) at 5 years after surgery. PATIENTS AND METHODS From June 2005 to January 2007, 65 obese patients underwent SG. The percentage of excess weight loss (%EWL) and excess BMI loss (% EBL), obesity-related co-morbidities, and post-SG complications were evaluated at 2 years after SG based on our database, and at 5 years after SG based on a questionnaire sent to the patients by one of the authors (IB) between May 2011 and February 2012. RESULTS A complete data set was obtained for 53 of 65 patients (82%), including 45 patients who had SG as the only surgical treatment, and eight patients who had a second bariatric procedure at a later date because of insufficient weight loss (five gastric bypass (GBP), three SG revision). For these 53 patients, the mean %EWL was 54.4% at 2 years and 53.7% at 5 years, and the mean %EBL was 61% at 2 years and 60% at 5 years. Three patients (5.7%) had post-operative complications (two fistulas (3.8%), one hemorrhage (1.9%)). Three trocar-site hernias (5.7%) were observed between 10 months and 34 months post-SG. Sub-group analysis of the 45 patients who underwent SG alone showed a mean %EWL of 57.1% at 2 years and 50.7% at 5 years; the mean %EBL was 64% at 2 years and 56.8% at 5 years. Of these 45 patients, 13 (28.9%) required medication to treat diabetes (DM) before SG and only five (11.1%) at 5 years after SG (61.5% decrease); 18 (40%) had antihypertensive treatment before SG, and eight (17.8%) at 5 years after SG (55.5% decrease); 12 (26.7%) took lipid-lowering medication before SG, and five (11.1%) at 5 years after SG (58.3% decrease); 24 (53.3%) had sleep apnea (SAS) before SG and six (17.8%) at 5 years after SG (75% decrease). However, while only five patients (11.1%) had GERD requiring PPI therapy before SG, 15 patients required PPI therapy (33.3%) at 5 years after SG (200% increase). CONCLUSION Five years after performance of SG, weight loss was satisfactory, few complications were observed, the reduction of co-morbidities was significant, but there was an increase in the frequency of GERD.

Abstract
OBJECTIVE Due to a strong genotype-phenotype correlation, the timing of prophylactic thyroidectomy in rearranged during transfection (RET) gene mutation carriers is usually dictated by genetic analysis. SUBJECTS AND METHODS We report a nationwide retrospective study of the clinical data of 77 French patients from 19 families with a mutation in codon 790 of the RET proto-oncogene. RESULTS The average age at diagnosis was 35.6 years ± 20.5. Thirty-nine patients were women. Fifty-five patients underwent operations for the treatment of medullary thyroid carcinoma (MTC) at the mean age of 38 years (4-82 years). The mean follow-up duration was 89 months. TNM staging was as follows: T0NxMx in 19, TxNxMx in 1, T1NxMx in 22, T1N1Mx in 8, T2N1Mx in 1 and T3N1Mx in four patients. In the T1/x-Nx group, 96% were considered cured after surgery. In the N1 group (n=13), six patients had multifocal disease and five patients were cured. Age and gender were not significant predictors of remission. Twenty-two patients did not undergo an operation (age 1.5-78 years); among them, 11 patients had a mean basal calcitonin (CT) level of 9.8 pg/ml (2-24) after 53 months of follow-up. One patient had been operated on for phaeochromocytoma (PHEO), and their CT level remained normal for 262 months. CONCLUSIONS This study confirms that RET 790 mutation is associated with a non-aggressive form of multiple endocrine neoplasia type 2, as 28% of the patients were followed up without thyroidectomy, 25% had been thyroidectomised with no tumour being detected and even patients with MTC had slow-evolving disease. Moreover, only one patient had PHEO, and no-one had primary hyperparathyroidism.

Abstract
BACKGROUND Abdominal pain is common in patients with functional bowel disorders (FBDs). The aim of this study was to characterize the predominant sites of abdominal pain associated with FBD subtypes, as defined by the Rome III criteria. METHODS A total of 584 consecutive patients attending FBD consultations in a tertiary center participated in the study. Stool form, abdominal pain location (nine abdominal segments), and pain intensity (10-point Likert scale) during the previous week were recorded. Logistic regression analysis was used to characterize the association of abdominal pain sites with specific FBD subtypes. KEY RESULTS FBDs were associated with predominant pain sites. Irritable bowel syndrome (IBS) with constipation was associated with pain in the left flank and patients were less likely to report pain in the right hypochondrium. Patients with functional constipation reported pain in the right hypochondrium and were less likely to report pain in the left flank and left iliac site. IBS with alternating constipation and diarrhea was associated with pain in the right flank, and unsubtyped IBS with pain in the hypogastrium Patients with functional abdominal pain syndrome reported the lower right flank as predominant pain site. Patients with unspecified FBDs were least likely to report pain in the hypogastrium. Patients with functional diarrhea, IBS with diarrhea, or functional bloating did not report specific pain sites. CONCLUSIONS & INFERENCES The results from this study provide the basis for developing new criteria allowing for the identification of homogeneous groups of patients with non-diarrheic FBDs based on characteristic sites of pain.

Abstract
Heart rate (HR) predicts cardiovascular morbidity and mortality in individuals either with or without diabetes. In type 2 diabetic patients, cardiac autonomic neuropathy is a risk marker for cardiac morbidity and mortality. A major pathogenic potential may be attributed to vagal depression and sympathetic predominance. In this issue of Diabetologia, Berkelaar et al (DOI: 10.1007/s00125-013-2848-6 ) examined the effects of euglycaemic, and hyperglycaemic clamp with the addition of glucagon-like-peptide-1 (GLP-1) and arginine, on cardiac vagal control in a large number of healthy subjects. After adjustments for age, BMI and insulin sensitivity, insulin associations with HR remained partially intact while those with vagal control disappeared. This suggested that BMI and insulin sensitivity, but not insulin levels, were the main drivers of cardiac vagal control. GLP-1 infusion during hyperglycaemia increased HR and BP and produced a statistically non-significant decrease in measures of cardiac vagal control compared with values before any manipulation of insulin levels. This commentary summarises how, and to what extent, insulin and GLP-1 affect autonomic nervous system activity, HR and BP. More information is needed on the mechanisms through which acute administration of, and long-term treatment with, GLP-1 may affect haemodynamics and autonomic activity in diabetic and obese patients, since this may influence cardiovascular outcomes.

Abstract
BACKGROUND Obesity is considered as a risk factor for many functional digestive disorders. The aim of the present study was to evaluate the prevalence and the association of functional digestive symptoms affecting the upper and the lower digestive tract in patients eligible for bariatric surgery. METHODS Before surgery, 120 consecutive patients with normal upper endoscopy (7.5% males, mean BMI 44 ± 6 m/kg(2)) have filled a standard questionnaire in order to evaluate the presence of depressive symptoms and functional digestive disorders according to the Rome criteria. The major symptoms (esophageal, gastroduodenal, anorectal, and abdominal pain) were coded as dichotomous variables. Data analysis was performed using multivariate logistic regression with a backwards selection procedure adjusted only for the variables that were significant in univariate analysis (p < 0.05). RESULTS Functional symptoms were present in 89% of the subjects (2.5 functional digestive symptoms/subject). Depression symptoms were found in 43% of the patients. Esophageal symptoms were independent predictors for the presence of gastric, bowel, and anorectal symptoms. Functional abdominal pain and bowel symptoms were present, respectively, in 19% and 84% of the patients. Approximately half of the patients have specific functional bowel disorders (28.6% constipation, 18% irritable bowel syndrome, 18% diarrhea, 1% bloating) and 35.7% have non-specific bowel disorders. Anorectal symptoms were found in 40% of the patients: difficult defecation in 32% and fecal incontinence in 9.8% of the patients. Depression was an independent predictor for anorectal symptoms. CONCLUSIONS This study shows the high prevalence of functional bowel symptoms in patients complaining of morbid obesity.

Abstract
Objective. This prospective study evaluated laparoscopic sleeve gastrectomy for its safety and efficiency in excess weight loss (%EWL) in super superobese patients (BMI >60 Kg/m(2)). Results. Thirty patients (33 women and 7 men) were included, with mean age of 35 years (range 18 to 59). Mean preoperative BMI was 66 Kg/m(2) (range 60 to 85). The study included one patient with complete situs inversus and 4 (14%) with previous restrictive gastric banding. The mean operative time was 120 minutes (range 80 to 220 min) and the mean hospital stay was 7.5 days (4 to 28 days). There was no postoperative mortality or need for a laparotomy conversion. Two subphrenic hematomas, one gastric fistula, and one pulmonary embolism, were the major complications. After 18 months 17 (77%) had sufficient weight loss and six had insufficient results, leading to either re-sleeve gastrectomy (3), or gastric bypass (2). Three years after the initial laparoscopic sleeve gastrectomy, the mean EWL was 51% (range 21 to 82). Conclusion. The laparoscopic sleeve gastrectomy is a safe and efficient operating procedure for treating super superobesity. In the case of insufficient weight loss, a second-stage operation like resleeve gastrectomy or gastric bypass can be proposed.

Abstract
Introduction The occurrence of an intravascular lymphoma with severe pulmonary involvement mimicking pulmonary embolism is described. Case presentation A 38-year-old man was referred to our intensive care unit with acute respiratory failure and long lasting fever. Appropriate investigations failed to demonstrate any bacterial, viral, parasitic or mycobacterial infection. A chest computed tomography scan ruled out any proximal or sub-segmental pulmonary embolism but the ventilation/perfusion lung scan concluded that there was a high probability of pulmonary embolism. The cutaneous biopsy pathology diagnosed intravascular lymphoma. Conclusion Intravascular lymphoma is a rare disease characterized by exclusive or predominant growth of neoplastic cells within the lumina of small blood vessels. Lung involvement seems to be common, but predominant lung presentation of this disease is rare. In our patient, urgent chemotherapy, along with adequate supportive care allowed complete recovery.

Abstract
Autoimmune thyroxicosis and myasthenia gravis are often associated. In both diseases, clinical features may include neuromuscular weakness, making their distinction challenging. We report a patient with known Graves disease who presented with generalised fatigue, initially attributed solely to thyrotoxicosis, and who experienced severe respiratory failure linked to associated myasthenia gravis that was unmasked by medication used in the perioperative management of his thyroxicosis. Anaesthetists should always consider myasthenia gravis in cases of hyperthyroidism presenting with neuromuscular features.

Abstract
Recent studies indicate that pendrin, an apical Cl-/HCO3- exchanger, mediates chloride reabsorption in the connecting tubule and the cortical collecting duct and therefore is involved in extracellular fluid volume regulation. The purpose of this study was to test whether pendrin is regulated in vivo primarily by factors that are associated with changes in renal chloride transport, by aldosterone, or by the combination of both determinants. For achievement of this goal, pendrin protein abundance was studied by semiquantitative immunoblotting in different mouse models with altered aldosterone secretion or tubular chloride transport, including NaCl loading, hydrochlorothiazide administration, NaCl co-transporter knockout mice, and mice with Liddle's mutation. The parallel regulation of the aldosterone-regulated epithelial sodium channel (ENaC) was examined as a control for biologic effects of aldosterone. Major changes in pendrin protein expression were found in experimental models that are associated with altered renal chloride transport, whereas no significant changes were detected in pendrin protein abundance in models with altered aldosterone secretion. Moreover, in response to hydrochlorothiazide administration, pendrin was downregulated despite a marked secondary hyperaldosteronism. In contrast, alpha-ENaC was markedly upregulated, and the molecular weight of a large fraction of gamma-ENaC subunits was shifted from 85 to 70 kD, consistent with previous results from rat models with elevated plasma aldosterone levels. These results suggest that factors that are associated with changes in distal chloride delivery govern pendrin expression in the connecting tubule and cortical collecting duct.

Abstract
Pendrin (Pds; Slc26A4) is a new anion exchanger that is believed to mediate apical Cl−/HCO3−exchange in type B and non-A-non-B intercalated cells of the connecting tubule and cortical collecting duct. Recently, it has been proposed that this transporter may be involved in NaCl balance and blood pressure regulation in addition to its participation in the regulation of acid-base status. The purpose of our study was to determine the regulation of Pds protein abundance during chronic changes in chloride balance. Rats were subjected to either NaCl, NH4Cl, NaHCO3, KCl, or KHCO3loading for 6 days or to a low-NaCl diet or chronic furosemide administration. Pds protein abundance was estimated by semiquantitative immunoblotting in renal membrane fractions isolated from the cortex of treated and control rats. We observed a consistent inverse relationship between Pds expression and diet-induced changes in chloride excretion independent of the administered cation. Conversely, NaCl depletion induced by furosemide was associated with increased Pds expression. We conclude that Pds expression is specifically regulated in response to changes in chloride balance.
