Outcomes of bariatric surgery in patients with inflammatory bowel disease from a French nationwide database.

BACKGROUND: The outcomes of bariatric surgery (BS) in patients with chronic inflammatory bowel disease (IBD) remain rarely described. We aimed to evaluate the 90-day morbidity and mortality rates, and the risk of IBD complications 2 years after BS. METHOD: Patients from the French Programme de Médicalisation des Systèmes d'Information (PMSI) database who underwent a primary BS between 2016 and 2018 were included. We identified patients with a previous diagnosis of IBD. Postoperative 90-day (POD90) morbidity and mortality rates were compared between the two groups. The evolution of IBD was followed 2 years after BS. RESULTS: Between 2016 and 2018, 138 980 patients underwent primary BS, including 587 patients with IBD: 326 (55.5 per cent) with Crohn's disease (CD) and 261 (44.5 per cent) with ulcerative colitis (UC). The preferred surgical technique was sleeve gastrectomy, especially in the IBD group (81.1 per cent), followed by gastric bypass (14.6 per cent). Patients with IBD had more comorbidities (Charlson Comorbidity Index of 1 or more, hypertension, and diabetes; P < 0.001) than those without IBD. The POD90 mortality rate did not differ between the two groups (0.049 per cent in the IBD group versus 0 per cent in the non-IBD group), but more unscheduled rehospitalizations at POD90 were observed in patients with IBD (6.0 per cent versus 3.7 per cent; P = 0.004). Two years after BS, 86 patients (14.6 per cent) in the IBD group had at least one unplanned readmission for the management of their IBD; 15 patients stayed for 3 or more days. After multivariable analysis, patients with CD had an independent elevated risk of IBD-related unplanned readmissions 2 years after BS versus UC (adjusted odds ratio 1.90, 95 per cent c.i. 1.22 to 2.97; P = 0.005). CONCLUSION: In a highly selected cohort of patients with well-controlled IBD, BS did not result in added mortality or morbidity. A point of vigilance must be underlined regarding BS in patients with CD.

Impact of donor comorbidities on heart transplant outcomes in the modern era.

OBJECTIVES: The use of marginal donors with cardiovascular risk factors is increasing due to organ shortage but remains controversial in heart transplantation (HTx). We sought to investigate post-transplant outcomes in the recent era taking into account donor characteristics. METHODS: We reviewed 261 HTx performed in our hospital between January 1996 and March 2013. Donor characteristics were obtained from the national database. The incidence of primary graft dysfunction (PGD) and cardiac allograft vasculopathy (CAV) and overall survival were compared in 2 groups of HTx recipients: those receiving transplants from 1996 to 2004 (Group A, n = 120) and from 2005 to 2013 (Group B, n = 141). RESULTS: The mean age of the donors was 34 ± 12 years in Group A vs 42 ± 13 years in Group B ( P < 0.001). Donors in Group B had a higher body mass index (23 ± 2 vs 26 ± 5 kg/m 2 , P < 0.001), were more likely to be smokers (29.6% vs 52.9%, P < 0.001) and were more likely to have hypertension (5% vs 13.5%, P = 0.030). There was no difference in survival at 1 and 5 years (79% and 63% in Group A vs 80% and 62% in Group B, respectively; P = 0.551). The rate of PGD was 36% in Group A vs 40% in Group B ( P = 0.092). Freedom from CAV at 5 years was 64% and 61%, respectively ( P = 0.367). Among the characteristics of the donors, only hypertension was associated with reduced survival. CONCLUSIONS: The use of older cardiac donors with more cardiovascular comorbidities in the recent era did not impair the post-transplant outcomes. Donor hypertension was the only determinant of worse survival.

Likely effect of the 2014 Ebola epidemic on HIV care in Liberia.

OBJECTIVE: Liberia's health system has been severely struck by the 2014 Ebola epidemic. We aimed to assess the potential effect of this epidemic on the care of HIV patient in two clinics [John F. Kennedy (JFK) and Redemption Hospitals] in Monrovia, which stayed open throughout the epidemic. DESIGN AND METHODS: A preexisting electronic database of HIV patient's follow-up visits was used to estimate three weekly parameters from January 2012 to October 2014: number of visits, number of new patient, and proportion of patients with follow-up delay. We used segmented negative binomial regressions to assess trends before and after the week of the Ebola outbreak defined in June 2014 by WHO. RESULTS: The cumulative number of patients in care comprised 5948 patients with a total of 56 287 visits between January 2012 and October 2014. From June 2014, the number of visit per week, stable since 2012, abruptly decreased (59%) in Redemption (P < 0.001) and progressively decreased by 3% per week in JFK (P < 0.001). In both the clinics, the weekly proportion of patient with follow-up delay sharply increased after the point break from June 2014 (P value < 0.001). From June 2014, a significant decrease in new patients per week occurred in both the clinics: by 57% (P value < 0.001) in Redemption and by 4.6% per week (P value < 0.001) in JFK. CONCLUSION: The Ebola epidemic had a significant effect on HIV care in Monrovia. Given the particular impact on the rate of patients with follow-up delay, a long-term impact is feared.

Comparison of Preoperative and Postoperative Characteristics in Octogenarians Having Isolated Surgical Aortic Valve Replacement Before Versus After Introduction of Transcatheter Aortic Valve Implantation.

Aortic stenosis (AS) is the most frequent heart valve disease. Surgical aortic valve replacement (SAVR) is the reference treatment. Transcatheter aortic valve implantation (TAVI) has emerged as an alternative treatment. New strategies for treating the AS are upcoming. The aim of the study was to assess if the clinical profile of octogenarian patients treated surgically before and after the TAVI program initiation has changed. We retrospectively included consecutive octogenarian patients, who underwent isolated SAVR, from January 2006 to December 2011 in a single high-volume center. We compared preoperative and postoperative characteristics before and after the initiation of TAVI (February 2009). Five hundred seventeen patients were included: 229 in the "pre-TAVI" group (2006 to 2008), 288 in the "post-TAVI" group (2009 to 2011). The mean age was 83.2 ± 2.0 in the "pre-TAVI" group, 83.5 ± 2.1 in the "post-TAVI" group (p = 0.106). There were no significant differences in preoperative characteristics: New York Heart Association class (p = 0.374), history of heart failure (p = 0.680), left ventricular ejection fraction (59.8 ± 12.2% in the "pre-TAVI" group, 59.9 ± 11.3% in the "post-TAVI" group, p = 0.922), coronary artery disease (p = 0.431), chronic pulmonary disease (p = 0.363), and previous cardiac surgery (p = 0.085). The logistic EuroSCORE was 7.78 ± 4.60% in the "pre-TAVI" group and 7.33 ± 3.96% in the "post-TAVI" group (p = 0.236). The operative mortality (30-day) was comparable: 5.2% in the "pre-TAVI" group, 6.9% in the "post-TAVI" group (p = 0.424). Thus, with the emergence of TAVI, the number of octogenarian patients operated on, their preoperative characteristics, and the operative mortality remained comparable.

Logistic EuroSCORE I risk analysis in aortic valve reoperations after bioprosthetic replacement.

BACKGROUND AND AIM OF THE STUDY: The aim was to evaluate the early and long-term results of redo-aortic valve replacement (AVR) for dysfunctioning bioprostheses, according to the type of bioprosthesis failure. The performance of the EuroSCORE in predicting operative mortality was addressed. METHODS: A retrospective analysis was performed of 164 patients who had undergone redo-AVR at the authors' institution. All data were collected prospectively. The type of bioprosthesis failure was categorized as either structural valve dysfunction (SVD), non-structural vale dysfunction (NSVD), or infective endocarditis (IE). The logistic EuroSCORE I was obtained, and a formal analysis of its predictive performance was conducted. RESULTS: The mean logistic EuroSCORE was 26.3 +/- 20.6%, while the observed operative mortality was 10.6%. The EuroSCORE overestimated mortality in all subgroups of indication; operative mortality was higher among the NSVD (14.7%) and IE (13.9%) groups, and lower among SVD patients (8.5%). The performance of the EuroSCORE in predicting mortality was better in SVD patients, and worse in NSVD patients (areas under the ROC curve of 0.857 and 0.751, respectively). Only patient-related factors independently predicted the operative mortality (logistic regression). The SVD patients displayed a significantly better long-term survival compared to NSVD and IE patients. Patient-related factors were seen to be the determinants of long-term survival. CONCLUSION: Redo-AVR can be performed with good early and long-term results, despite a high predicted risk. The logistic EuroSCORE I globally overestimates the risk, and its performance varies considerably according to the indication for redo-AVR. Therefore, it should not be used to determine the application of valve-in-valve procedures. The type of indication for redo-AVR (SVD, NSVD, IE) defines three different profiles of patients having distinctive early and long-term behaviors.

Long-term effects of therapeutic education for patients with rheumatoid arthritis.

INTRODUCTION: The objective of this study was to assess the effects of an educational program on the course of rheumatoid arthritis (RA) after 3 years. METHODS: From December 2002 to December 2003, 39 RA patients participated in a 3-day education program delivered to groups of four or five patients. Effects of the program were evaluated after 3 years in 33 patients, comparatively to baseline, based on the following variables: knowledge of RA (self-questionnaire), disease activity (DAS 28), functional impairment (health assessment questionnaire [HAQ]) and quality of life (arthritis impact measurement scale 2 [AIMS2], short-form). We also compared patient knowledge in the educational program participants and in 38 controls with RA. Direct questions were used to evaluate the program after 3 years. RESULTS: Patient knowledge 3 years after the education program was significantly improved compared to baseline (P<0.0001) and was significantly better than in the controls (P<0.0001). Disease activity was significantly lower in the education group after 3 years than at baseline (DAS28, 3.1 vs. 3.8, P<0.005). Neither the HAQ nor the AIMS2 scores changed significantly after 3 years compared to baseline. The replies to the direct questions indicated a very high level of overall satisfaction with the educational program. CONCLUSION: An educational program tailored to patient needs can produce lasting improvements in knowledge of the disease and may help to control the activity of RA. These results warrant the development of education programs for patients with chronic inflammatory joint disease.

Serum transferrin saturation increase is associated with decrease of antibacterial activity of serum in patients with HFE-related genetic hemochromatosis.

OBJECTIVES: Patients with type 1 (HFE-related) genetic hemochromatosis are usually excluded from blood donation on the basis that this disease may facilitate bacterial infections. The aim of the present study was to evaluate the serum antibacterial effect against Salmonella enterica Typhimurium LT2 in relation to iron status. METHODS: Serum samples were collected in 26 iron-overloaded (homozygous C282Y mutation) and 35 iron-depleted hemochromatosis patients and 33 healthy control subjects. The antibacterial activity of sera and iron parameters were tested for each patient. RESULTS: Serum from normal controls had an antibacterial effect against Salmonella Typhimurium LT2. The antibacterial effect decreased from the 1:2 to the 1:8 dilution and was always significantly lower in the iron-overloaded group. In both control and iron-depleted patients, a positive correlation was found between the decrease of antibacterial effect and the increase of both serum iron and transferrin saturation. CONCLUSIONS: These results (a) support the view that chronic iron overload decreases serum antibacterial effect against Salmonella enterica Typhimurium LT2, (b) favor the interest of including, besides serum ferritinemia, serum transferrin saturation levels as a further criterion for iron-depletive treatment efficacy, and (c) provide an argument for not discouraging the use of blood from iron-depleted hemochromatosis patients for transfusion.

Resting echocardiographic assessments of left atrial function and filling pressure interest in the understanding of exercise capacity in patients with chronic congestive heart failure.

OBJECTIVE: Doppler echocardiography is well recognized as the primary noninvasive imaging technique to assess global and regional cardiac function. Cardiopulmonary exercise testing has become a powerful tool to predict outcome in chronic heart failure (CHF). We looked for cardiac determinants, using resting echocardiographic parameters, of exercise tolerance in patients with CHF. METHODS: Transthoracic echocardiography and standardized cardiopulmonary exercise testing were performed in 75 patients (59 +/- 11 years) with CHF, New York Heart Association functional class II to III. Systolic and diastolic function, filling pressures, and left ventricular, right ventricular, and left atrial (LA) regional function were assessed using Doppler tissue velocities and strain values. RESULTS: Maximal workload (86 +/- 41 W) and peak oxygen (14.6 +/- 3.1 mL/min/kg) correlated with left ventricular filling pressure estimates (E/Ea and E/Vp) but also with end-diastolic pulsed Doppler tissue velocity at the mitral annulus (Aa), LA volume, and regional LA function assessed by strain analysis. In multivariate analysis, maximum workload and peak oxygen were shown to correlate with right ventricular peak strain, although Aa and E/Ea were the best predictors of exercise capacity. CONCLUSION: Capacity to exercise in patients with CHF is understandable by resting echocardiography. Filling pressures, and LA and right ventricular functions, are its cardiac best determinants. Adding Aa peak velocity in resting echocardiographic evaluation of patients with CHF is found useful.

Edwards Mira bileaflet prosthesis in aortic position: midterm results of a prospective multi-centre study.

This prospective multicentre study assessed the midterm clinical and haemodynamic results of the Edwards Mira curved bileaflet prosthesis in aortic position. From June 1998 to October 2000, 117 patients, mean age 64 years (31-78 years) underwent aortic valve replacement with the Edwards Mira valve in three institutions. Clinical status, haemodynamic performance and valve related complications were assessed. Serial echocardiographic examinations were performed at discharge and at least two years follow-up. Operative mortality was 1.7% (n=2). Follow-up was 100% complete (594.1 patient-years). Actuarial survival at one, three and five years was 96.5+/-1.7%, 93.9+/-2.2% and 88.4+/-3.0%, respectively. Freedom from thrombosis was 99.1+/-0.9%, from embolic events: 96.2+/-1.9%, from bleeding events: 96.4+/-1.7%, and from non-structural dysfunction 97.2+/-1.6%. There was no structural dysfunction. The peak gradient at discharge was 22.13+/-8.1 mmHg down to 20.8+/-8 mmHg at 28 months. The mean gradient at discharge was 12.7+/-4.5 mmHg at discharge down to 10.8+/-4.2 mmHg at 28 months. The permeability index was 53.3+/-10% at 28 months. The Edwards Mira aortic valve showed excellent midterm haemodynamic performance, good midterm survival and low valve related complications rate. Long term follow-up remains to be assessed.

Current hospital mortality of aortic valve replacement in octogenarians.

BACKGROUND AND AIM OF THE STUDY: The increasing incidence of cardiovascular disease with age, coupled to a constant extension of life expectancy in industrialized countries, is leading to an ever-increasing number of elderly patients being referred for aortic valve replacement (AVR). In light of advances in surgical technology and cardiac protection, the operative mortality and risk factors have been updated in order to specify surgical indications. METHODS: Between January 2000 and December 2004, a total of 442 patients (203 males, 239 females) aged > or =80 years (mean age 82.7 +/- 2.3 years) underwent AVR at the authors' institution. Surgery was either isolated (n = 344) or associated with coronary revascularization (n = 86), mitral valvuloplasty (n = 5) or aortic surgery (n = 7). Seventeen patients had undergone previous cardiac surgery. The EuroScore was calculated for each patient. RESULTS: Overall operative mortality was 7.5% (n = 33). Independent predictive factors of mortality were: aortic insufficiency (30%, p <0.004), NYHA class IV (20.5%, p < 0.001), left and right heart failure (11.5% and 19.4%, p <0.02), chronic renal insufficiency (18.5%, p <0.04), emergency (37.5%, p <0.001, OR = 4.7), left ventricular ejection fraction (21.1%, p <0.004, OR = 0.9), and redo surgery (35.3%, p <0.001, OR = 6). Mortality was also increased in case of associated coronary revascularization (11.6%), mitral or tricuspid surgery (20%) and ascending aorta procedure (25%). CONCLUSION: Patient functional improvement achieved after valve replacement at the cost of a rather low operative mortality justifies considering octogenarians for surgery. However, decisions should be taken on an individual basis. An earlier referral to surgery before the onset of altered cardiac function could lead to further reductions in hospital mortality.

[Cardiac surgery in the elderly]. / La chirurgie cardiaque du sujet agé.

Cardiac disease in the elderly represents a major burden on public healthcare. Their frequences is linked to ageing process of general population and prevalence of cardiovascular diseases in older ages. Two diseases are of primary importance in elderly: Aortic valve stenosis is the most common. Valve replacement is the procedure of choice in the majority of patients. In coronary artery disease, although drug eluting stents have improved the results of percutaneous coronary intervention, coronary artery bypass grafts have still has an important place in the treatment of severe lesions: multivessel disease, left main and diabetes. Our report is a retrospective review of 8871 patients aged 70 years or more operated on between 1974 and 2004.
