Abstract
BACKGROUND Salivary fistulas remain a significant problem in patients undergoing major head and neck reconstructive surgery. Surgical sealants have become increasingly used in cutaneous and non-cutaneous wound closure, providing a barrier to fluids/gases and promoting healing. The purpose of this study was to determine the efficacy of a common surgical sealant, 2-Octyl Cyanoacrylate (2-OCA, Dermabond®), in the prevention of salivary fistulas following free flap reconstruction of the oral cavity. METHODS In this non-randomized, single arm prospective trial, patients undergoing free flap reconstruction of gravity-dependent oral cavity defects were recruited. Application of 2-OCA was performed along flap inset suture lines at the time of surgery. Prospectively collected trial data were propensity score matched to a control cohort to compare outcomes. Data collected include demographics, medical co-morbidities, previous treatments, primary tumor site, and subsites reconstructed. The primary outcome measure was rate of salivary fistula formation. Secondary outcomes were time to development of leak and percentage of patients tolerating oral feeding at one month post-operatively. RESULTS In the 46 propensity score matched pairs, eight (17.4%) out of 46 patients in the 2-OCA prospective cohort and seven (15.2%) out of 46 patients in the control cohort developed postoperative salivary fistulas within the one-month study interval (p = 1.00). The average time to postoperative leak in the 2-OCA group was 12.5 days versus 7.1 days in the control cohort (p = 0.10). In the 2-OCA group, 30 (65.2%) patients were tolerating regular diet at one month post-operatively compared to 33 (71.7%) in the control cohort (p = 0.65). CONCLUSION Salivary fistula rates after application of a 2-OCA surgical sealant were not improved compared to a control cohort in this single institutional trial. There are several surgical sealants available, each with varying elasticity and adhesiveness. Future studies are needed to identify surgical sealants that are able to provide sufficient strength and adhesion to seal closures and combat corrosive saliva, but elastic enough to handle motion related tension during swallowing and post-operative movements in the head and neck.

Abstract
Hartmann's reversal procedures are often fraught with complications or failure to recover. This being a fact, it is often difficult to select patients with the optimal indications for a reversal. The post-recovery morbidity and mortality rates in the literature are heterogeneous between 0.8 and 44%. The identification of predictive risk factors of failure of such interventions would therefore be very useful to help the practitioner in his approach. Given these elements, it was important to us to analyze the practice of two French university hospitals in order to highlight such risk factors and to allow surgeons to select the best therapeutic strategy. We performed a bicentric observational retrospective study between 2010 and 2015 that studied the characteristics of patients who had undergone Hartmann surgery and were subsequently reestablished. The aim of the study was to identify factors influencing morbidity and postoperative mortality of Hartmann's reversal. Primary outcome was complications within the first 90 postoperative days. 240 patients were studied of which 60.4% were men. The mean age was 69.48 years. The median time to reversal was 8 months. 79.17% of patients were operated as emergency cases where the indication was a diverticular complication (39.17%). Seventy patients (29.2%) underwent a reversal and approximately 43% of these had complications within the first 90 postoperative days. The mean age of these seventy patients was 61.3 years old and 65.7% were males. None of them benefited from a reversal in the first three months. We identified some risk factors for morbidity such as pre-operative low albuminemia (p = 0.005) and moderate renal impairment (p = 0.019). However, chronic corticosteroid use (p = 0.004), moderate renal insufficiency (p = 0.014) and coronary artery disease (p = 0.014) seem to favour the development of anastomotic fistula, which is itself, a risk factor for mortality (p = 0.007). Our study highlights an important rate of complications including significant anastomotic fistula after Hartmann's reversal. Precarious nutritional status and cardiovascular comorbidities should clearly lead us to reconsider the surgical indication for continuity restoration.

Abstract
BACKGROUND It is well known that total thyroidectomy is feasible on elderly patients but is linked to complications because of their underlying comorbidities. In this study we analyzed the specific risks linked to surgery, hypoparathyroidism and recurrent nerve palsy. METHODS materials-methods:Prospective, multicentre trial conducted at 13 hospital sites. The primary endpoint was the percentage of patients with postoperative hypocalcaemia (albumin-corrected serum calcium level <2 mmol/L at day 2). Secondary endpoints included recurrent nerve palsy rate at day 2, the percentage of patients with hypocalcaemia (serum calcium level <2 mmol/L) and recurrent nerve palsy at month 6, operating durations and postoperative pain. Patients were separated in two groups: <70 years and ≥70 years old. RESULTS In total, 1329 patients who underwent total thyroidectomy were included (median age 51.17 years [18.10; 80.90], 80% women, and hyperthyroidism in 20%, 101 ≥ 70 years old). Rates of hypocalcaemia at day 2 and month 6 were 20.02% and 1.98% respectively. Nasofibroscopy showed postoperative abnormal vocal cord motility in 9.92% cases (hypo-motility 5.76% - immobility 4.16%) and 0.95% at month 6 (hypo-motility 0.48%, immobility 0.48%). Patients ≥70 years had a lower (but non-significant) postoperative and definitive hypocalcaemia rate than patients < 70 years: 14.85% vs 20.44% at day 2 (p = 0.1773) and 0% vs 2.15% at month 6 respectively (p = 0.2557). Abnormal vocal cord motility rate was 12.00% in patients ≥70 years vs 9.75% in patients <70 years at day 2 (p = 0.4702), and 2.06% in patients ≥70 years vs 0.86% at month 6 (p = 0.2340). CONCLUSIONS Total thyroidectomy in patients ≥70 years is feasible and safe. Age does not increase the morbidity. The study is registered with ClinicalTrials.gov number NCT01551914.

Abstract
BACKGROUND Pediatric heart transplant (PedHtx) patients have increased cardiovascular risk profiles that affect their long-term outcomes and quality of life. We designed a 12- to 16-week diet and exercise intervention delivered via live video conferencing to improve cardiovascular health. Our methodology and baseline assessment of the first 13 enrolled patients are reported. METHODS Inclusion criteria are as follows: (a) 8-19 years old; (b) heart transplant >12 months; (c) ability to fast overnight; (d) cardiac clearance by cardiologist; and (e) presence of an adult at home during exercise sessions for patients <14 years old. Exclusion criteria are as follows: (a) acute illness; (b) latex allergy; (c) transplant rejection <3 months ago; and (d) multi-organ transplantation. The intervention consists of one diet and three exercise sessions weekly via live video conferencing. Study visits are conducted at baseline, intervention completion, and end of maintenance period. RESULTS A total of 13 participants (15.2 [2.3] years) have been enrolled. Median percent-predicted VO2 max was 56.8 [20.7]% (10 patients <70%). Ten patients had abnormal endothelial function (reactive hyperemia index <1.9; 1.4 [0.325]) and 11 patients had stiff arteries (pulse wave velocity ≧5.5 m/s for 15-19 years, ≧4.5 m/s for 8-14 years; 5.6 [0.7] m/s). Patients had suboptimal diets (saturated fat: 22.7 [23.8] g/d, sodium: 2771 [1557] mg/d) and were sedentary at a median of 67.5 [13.8]% of their time. CONCLUSIONS Baseline assessment confirms that PedHtx patients have abnormal cardiac, vascular, and functional health indices, poor dietary habits, and are sedentary. These results support the rationale to test the feasibility and impact of a non-pharmacologic lifestyle intervention in this patient population.

Abstract
The predictive value of coronary artery calcium (CAC) in heart transplant (HTX) patients is not established. We explored if the absence of CAC on computed tomography (CT) could exclude moderate and severe cardiac allograft vasculopathy [CAV2-3 ; the International Society for Heart and Lung Transplantation (ISHLT) recommended nomenclature] and significant coronary artery stenosis (diameter reduction ≥50%) and predict long-term clinical outcomes. HTX recipients (n = 133) were prospectively included and underwent CT for CAC scoring and invasive coronary angiography (ICA) 7.8 ± 5.0 years after HTX. CAC was detected in 73 (55%) patients. The absence of CAC on CT had a negative predictive value of 97% for ISHLT CAV2-3 and 88% for significant stenosis on ICA. During 7.5 ± 2.6 years of follow-up after CAC CT (n = 127), there were 57 (45%) nonfatal major adverse cardiac events and 23 (18%) deaths or graft losses registered as first events. Patients with CAC had significantly more events (P = 0.011). In an adjusted Cox regression analysis, the presence of CAC was significantly associated with a negative outcome (HR 1.8, 95% CI 1.1-3.0; P = 0.023). The absence of CAC predicted low prevalences of ISHLT CAV2-3 and significant coronary artery stenosis in HTX patients. The presence of CACS was significantly associated with a worse long-term outcome.

Pediatric transplantation. 2018;(4):e13170
Abstract
We sought to investigate whether magnesium oxide bound to soy protein (MGP) increases serum magnesium concentrations with less diarrhea compared to commonly prescribed magnesium salts. Subjects were switched to MGP at a near-equivalent daily elemental magnesium dose. Mean serum magnesium levels were compared. If magnesium levels remained <1.7 mg/dL after switching to MGP, subjects were enrolled into Part 2 and received a one-time MGP dose adjustment. The MGP daily dose was increased by 266 mg. For both parts 1 and 2, subjects recorded the number and quality of their stools to assess gastrointestinal (GI) tolerability of MGP. Twelve pediatric kidney transplant recipients completed Part 1. Mean serum magnesium levels increased from 1.61 (SD 0.1) on standard MG to 1.69 (SD 0.1); t(11) = 2.6, P = .02 on MGP. Five subjects completed Part 2, and all achieved serum magnesium ≥1.7 mg/dL (mean 1.75 mg/dL, SD 0.06; t(4) = 2.7, P = .06). Subjects reported the same number of, but looser bowel movements with MGP; however, individuals did not perceive intolerable GI symptoms with MGP therapy and all chose to remain on MGP at the end of the study. At an equivalent mg/kg/d dose of elemental magnesium, serum magnesium levels on MGP were significantly higher.

Abstract
BACKGROUND Optical coherence tomography (OCT)-based studies of cardiac allograft vasculopathy (CAV) published thus far have focused mainly on frame-based qualitative analysis of the vascular wall. Full capabilities of this inherently 3-dimensional (3D) imaging modality to quantify CAV have not been fully exploited. METHODS Coronary OCT imaging was performed at 1 month and 12 months after heart transplant (HTx) during routine surveillance cardiac catheterization. Both baseline and follow-up OCT examinations were analyzed using proprietary, highly automated 3D graph-based optimal segmentation software. Automatically identified borders were efficiently adjudicated using our "just-enough-interaction" graph-based segmentation approach that allows to efficiently correct local and regional segmentation errors without slice-by-slice retracing of borders. RESULTS A total of 50 patients with paired baseline and follow-up OCT studies were included. After registration of baseline and follow-up pullbacks, a total of 356 ± 89 frames were analyzed per patient. During the first post-transplant year, significant reduction in the mean luminal area (p = 0.028) and progression in mean intimal thickness (p = 0.001) were observed. Proximal parts of imaged coronary arteries were affected more than distal parts (p < 0.001). High levels of LDL cholesterol (p = 0.02) and total cholesterol (p = 0.031) in the first month after HTx were the main factors associated with early CAV development. CONCLUSIONS Our novel, highly automated 3D OCT image analysis method for analyzing intimal and medial thickness in HTx recipients provides fast, accurate, and highly detailed quantitative data on early CAV changes, which are characterized by significant luminal reduction and intimal thickness progression as early as within the first 12 months after HTx.

Abstract
BACKGROUND AND AIMS Obesity associated with diabetes mellitus is a significant worldwide problem associated with considerable health care costs. Whilst surgical intervention is effective, it is invasive, costly and associated with complications. This study aims to evaluate the safety and efficacy of the EndoBarrier®, a duodenal-jejunal sleeve bypass as an alternative treatment of diabetes mellitus in obese patients. MATERIALS AND METHODS This was a multi-centre, non-randomised trial recruiting obese patients with type 2 diabetes from three sites in the UK. Eligible participants had a BMI of 30-50 kg/m2 and HbA1c levels of 7.5-10%. The study comprised a 12-month period with the EndoBarrier® inserted and a 6-month follow-up period after it had been explanted. The primary study outcomes were weight, BMI, HbA1c levels and fasting insulin and glucose levels. RESULTS Forty-five patients were recruited and 31 patients (69%) completed the 12-month study period. Significant reductions in weight (95%CI 0.62-29.38; p < 0.05) and BMI (95%CI 1.1-8.7; p < 0.005) were documented 12 months after device insertion. The mean HbA1c was significantly reduced (95%CI 0.1-1.6; p < 0.05) after the device insertion period and reductions in metabolic parameters (fasting insulin and glucose levels) were also documented during the study. Adverse events were also assessed in all patients, the vast majority of which were reported as mild. CONCLUSIONS The EndoBarrier® appears to be a safe and effective treatment strategy in overweight patients with poor glycaemic control despite medical therapy, or in those who are eligible but decline bariatric surgery.

[Action of Calendula officinalis essence on bone preservation after the extraction].
Uribe-Fentanes, LK, Soriano-Padilla, F, Pérez-Frutos, JR, Veras-Hernández, MA
Revista medica del Instituto Mexicano del Seguro Social. 2018;(1):98-105
Abstract
BACKGROUND Calendula officinalis is a phytodrug used as analgesic, antiseptic and wound-healing agent due to its collagenogenic effect, which is why it is a convenient and affordable treatment that promotes alveolar bone preservation after tooth extraction in vivo. The aim of this study was to use Calendula officinalis during and after tooth extraction to determine its ability to preserve bone after this procedure. METHODS We established two groups matched by age, gender and position of the third molar. We used with patients on the experimental group Calendula officinalis diluted 10% as an irrigant during surgical extraction of third molars. We performed the conventional way with the control group irrigating with saline solution. Subsequently, both groups continued to make mouthwash for a week with the irrigating agent. Every week for a month, each patient underwent periapical radiography, out of which we took measurements of alveolar ridges and depth of alveolar bone, which were compared. CONCLUSIONS There is statistically significant evidence to state that Calendula officinalis favorably affects bone preservation after extraction.

Abstract
IMPORTANCE Acute isovolemic anemia occurs when blood loss is replaced with fluid. It is often observed after surgery and negatively influences short-term and long-term outcomes. OBJECTIVE To evaluate the efficacy and safety of ferric carboxymaltose to treat acute isovolemic anemia following gastrectomy. DESIGN, SETTING, AND PARTICIPANTS The FAIRY trial was a patient-blinded, randomized, phase 3, placebo-controlled, 12-week study conducted between February 4, 2013, and December 15, 2015, in 7 centers across the Republic of Korea. Patients with a serum hemoglobin level of 7 g/dL to less than 10 g/dL at 5 to 7 days following radical gastrectomy were included. INTERVENTIONS Patients were randomized to receive a 1-time or 2-time injection of 500 mg or 1000 mg of ferric carboxymaltose according to body weight (ferric carboxymaltose group, 228 patients) or normal saline (placebo group, 226 patients). MAIN OUTCOMES AND MEASURES The primary end point was the number of hemoglobin responders, defined as a hemoglobin increase of 2 g/dL or more from baseline, a hemoglobin level of 11 g/dL or more, or both at week 12. Secondary end points included changes in hemoglobin, ferritin, and transferrin saturation levels over time, percentage of patients requiring alternative anemia management (oral iron, transfusion, or both), and quality of life at weeks 3 and 12. RESULTS Among 454 patients who were randomized (mean age, 61.1 years; women, 54.8%; mean baseline hemoglobin level, 9.1 g/dL), 96.3% completed the trial. At week 12, the number of hemoglobin responders was significantly greater for ferric carboxymaltose vs placebo (92.2% [200 patients] for the ferric carboxymaltose group vs 54.0% [115 patients] for the placebo group; absolute difference, 38.2% [95% CI, 33.6%-42.8%]; P = .001). Compared with the placebo group, patients in the ferric carboxymaltose group experienced significantly greater improvements in serum ferritin level (week 12: 233.3 ng/mL for the ferric carboxymaltose group vs 53.4 ng/mL for the placebo group; absolute difference, 179.9 ng/mL [95% CI, 150.2-209.5]; P = .001) and transferrin saturation level (week 12: 35.0% for the ferric carboxymaltose group vs 19.3% for the placebo group; absolute difference, 15.7% [95% CI, 13.1%-18.3%]; P = .001); but there were no significant differences in quality of life. Patients in the ferric carboxymaltose group required less alternative anemia management than patients in the placebo group (1.4% for the ferric carboxymaltose group vs 6.9% for the placebo group; absolute difference, 5.5% [95% CI, 3.3%-7.6%]; P = .006). The total rate of adverse events was higher in the ferric carboxymaltose group (15 patients [6.8%], including injection site reactions [5 patients] and urticaria [5 patients]) than the placebo group (1 patient [0.4%]), but no severe adverse events were reported in either group. CONCLUSION AND RELEVANCE Among adults with isovolemic anemia following radical gastrectomy, the use of ferric carboxymaltose compared with placebo was more likely to result in improved hemoglobin response at 12 weeks.
