Benefits of Paediatric to Adult Transition Programme in Inflammatory Bowel Disease: The BUTTERFLY Study of GETECCU and SEGHNP.

(1) Background: Transition is a planned movement of paediatric patients to adult healthcare systems, and its implementation is not yet established in all inflammatory bowel disease (IBD) units. The aim of the study was to evaluate the impact of transition on IBD outcomes. (2) Methods: Multicentre, retrospective and observational study of IBD paediatric patients transferred to an adult IBD unit between 2017-2020. Two groups were compared: transition (≥1 joint visit involving the gastroenterologist, the paediatrician, a programme coordinator, the parents and the patient) and no-transition. Outcomes within one year after transfer were analysed. The main variable was poor clinical outcome (IBD flare, hospitalisation, surgery or any change in the treatment because of a flare). Predictive factors of poor clinical outcome were identified with multivariable analysis. (3) Results: A total of 278 patients from 34 Spanish hospitals were included. One hundred eighty-five patients (67%) from twenty-two hospitals (65%) performed a structured transition. Eighty-nine patients had poor clinical outcome at one year after transfer: 27% in the transition and 43% in the no-transition group (p = 0.005). One year after transfer, no-transition patients were more likely to have a flare (36% vs. 22%; p = 0.018) and reported more hospitalisations (10% vs. 3%; p = 0.025). The lack of transition, as well as parameters at transfer, including IBD activity, body mass index < 18.5 and corticosteroid treatment, were associated with poor clinical outcome. One patient in the transition group (0.4%) was lost to follow-up. (4) Conclusion: Transition care programmes improve patients' outcomes after the transfer from paediatric to adult IBD units. Active IBD at transfer impairs outcomes.

Lyophilized amniotic membrane graft for primary pterygium surgery: preliminary results.

The aim of this study was to investigate the tolerability, safety and efficacy of new lyophilized amniotic membrane (LAM) presentation for ocular use. A prospective case-series cohort of four patients with primary nasal pterygium which undergone excision and LAM implantation was evaluated for complications and clinical outcomes. Surgical manipulation of LAM was also assessed. LAM was stiff and easy to manipulate as well as no tearing occurred during surgery or suturing. Ocular comfort was checked and similar among those patients with LAM glued or sutured. After 12 months, there were no issues about tolerability or adverse events. Lower cosmetic outcomes (recurrence) were stated in 3 patients. Our study showed that LAM could be an effective alternative to cryopreserved amniotic membrane for graft after pterygium excision surgery. Its main advantage, storage at room temperature, can make it of immediate availability. Further studies comparing clinical outcomes of pterygium surgery with cryopreserved amniotic membrane versus LAM would confirm the benefits of the last.

38†Lyophilized amniotic membrane for pterygium surgery: long-term outcomes.

PURPOSE: To investigate the tolerability, security and long-term efficacy of lyophilized amniotic membrane (LAM) as an alternative to cryopreserved amniotic membrane in pterygium surgery. MATERIAL AND METHODS: Prospective case series of patients with primary nasal pterygium who undergone pterygium surgery and LAM implant either with sutures or glue. Postoperative follow-up was until month 24. Clinical and cosmetic outcomes, quality of life (as ocular comfort), and complications were evaluated. RESULTS: LAM was stiff and easy to manipulate as well as no tearing occurred during surgery or suturing. 4 patients (3 males) had pterygium surgery and LAM implant two with sutures and the other two with glue. Ocular comfort was checked and similar among those patients with LAM glued or sutured. After 24 months, there were no issues about tolerability or adverse events. Lower cosmetic outcomes (recurrence) were stated in 3 patients. CONCLUSION: Our study showed that LAM could be an effective alternative to cryopreserved amniotic membrane for graft after pterygium excision surgery. Its main advantage, storage at room temperature, can make it of immediate availability. Further studies comparing clinical outcomes of pterygium surgery with cryopreserved amniotic membrane versus LAM would confirm the benefits of the last.

Global multi-site, prospective analysis of cataract surgery outcomes following ICHOM standards: the European CAT-Community.

PURPOSE: To evaluate in a large sample of patients from 10 different European centers the results of cataract surgery, characterizing the relationship between patient-reported outcomes (PROMs) and clinician-reported outcome measures (CROMs). METHODS: Prospective non-interventional multicenter observational descriptive study analyzing the clinical outcomes of a total of 3799 cases undergoing cataract surgery (mean age: 72.7 years). In all cases, the cataract surgery standard developed by the International Consortium for Health Outcomes Measurements (ICHOM) was used to register the clinical data. Three-month postoperative visual acuity and refraction data were considered CROMs, whereas Rasch-calibrated item 2 (RCCQ2) and total Catquest-9SF score (CQ) were considered PROMs. RESULTS: Postoperative corrected distance visual acuity (CDVA) was 0.3 logMAR or better in 88.7% (2505/2823) of eyes. Mean differences between preoperative and postoperative RCCQ2 and CQ scores were -3.09 and -2.39, respectively. Visual function improvement with surgery was reported by 91.5% (2163/2364) of patients. Statistically significant, although weak, correlations of postoperative CDVA with postoperative refraction, PROMs, and complications were found (0.133 ≤ r ≤0.289, p < 0.001). A predictive model (R2: 0.254) of postoperative CDVA considering 10 variables was obtained, including preoperative CDVA, different ocular comorbidities, age, gender and intraoperative complications. Likewise, another predictive model (R2: 0.148) of postoperative CQ considering a total of 14 variables was obtained, including additionally preoperative CQ, target refraction and previous surgeries. CONCLUSIONS: Cataract surgery provides an improved functional vision in most of patients although this improvement can be limited by ocular comorbidities and complications. The relationship between PROMs and CROMs is multifactorial and complex.

Visual Quality and Subjective Satisfaction in Ultrathin Descemet Stripping Automated Endothelial Keratoplasty (UT-DSAEK) versus Descemet Membrane Endothelial Keratoplasty (DMEK): A Fellow-Eye Comparison.

BACKGROUND: To analyze objective and subjective visual quality differences between descemet membrane endothelial keratoplasty (DMEK) and ultra-thin descemet stripping automated endothelial keratoplasty (UT-DSAEK) with a paired contralateral-eye design. METHODS: A cross-sectional, comparative, and observational case series study between DMEK and UT-DSAEK were presented. Visual acuity, refractive status and corneal quality assessment were compared between both endothelial keratoplasty techniques. The sample consisted of 20 eyes (10 patients) diagnosed with Fuchs endothelial corneal dystrophy. All measurements were performed preoperatively and at six months after surgery. Analyzed data included the measurement of objective scattering index, modulation transfer function, Strehl ratio, and optical quality assessment (OQAS) values. Contrast sensitivity, subjective patient satisfaction, visual acuity, tomography, pachymetry, endothelial cell count, and refraction status were also analyzed. RESULTS: Objective and subjective visual quality variables had similar results among UT-DSAEK and DMEK procedures. Statistically significant differences favoring DMEK against UT-DSAEK were found in endothelial cell density (658.80 ± 139.33 and 1059.00 ± 421.84 cells/mm2, respectively), pachymetry (621.20 ± 33.74 and 529.70 ± 30.00 µm, respectively), and follow-up (45.50 ± 24.76 and 15.50 ± 8.43 months, respectively). CONCLUSIONS: UT-DSAEK and DMEK revealed no differences in terms of objective and subjective visual quality. However, DMEK showed a faster recovery during the follow-up, increased endothelial cell density, lower pachymetry, and a more anatomical posterior keratometry against UT-DSAEK in this case series paired-eye study.

Postoperative treatment compliance rate and complications with two different protocols after pterygium excision and conjunctival autografting.

AIM: To evaluate compliance rate to pterygium postoperative treatment with two different protocols. METHODS: Review of clinical data of patients submitted to pterygium excision and conjunctival autografting in a single centre (and a single surgeon) in Barcelona between March 2014 and December 2017. Initial postoperative protocol (protocol 1) consisted of 4 months of topical steroids in a tapering fashion. Protocol 2 consisted of topical steroids tapered over 5 weeks. Compliance rate, complications and clinical outcomes were evaluated, and statistical comparisons were made. RESULTS: 120 surgeries were performed in 99 patients. Protocol 1 was applied in 63 cases and the next 57 followed protocol 2. Compliance with protocol 1 (57.6%) was lower than with protocol 2 (84.9%) (p = 0.002). Intraoperative complications (graft tear, corneal thinning, corneal perforation and bleeding) were found in 10 cases of protocol 1 and three cases of protocol 2, p = 0.08. Postoperative complications (graft dislocation, graft haematoma, ocular hypertension and recurrence) were found in 31 cases of protocol 1 (46.2%) and eight cases of protocol 2 (14%), p = 0.001. Six weeks after surgery, ocular hypertension was detected in eight cases corresponding to protocol 1 (13.6%) and two cases of protocol 2 (3.8%), p = 0.099. Recurrence rate during first year was higher in protocol 1 (26.3%) compared to protocol 2 (7.6%), p = 0.011. No cases of visual acuity worsening or infection were registered. CONCLUSION: Protocol 2 has shown to have higher compliance rate than protocol 1 and less postoperative complications, proving to be a safe and effective postoperative treatment after pterygium surgery.

Validity of Hemodynamic Monitoring Using Inert Gas Rebreathing Method in Patients With Chronic Heart Failure and Those Implanted With a Left Ventricular Assist Device.

OBJECTIVE: The present study assessed agreement between resting cardiac output estimated by inert gas rebreathing (IGR) and thermodilution methods in patients with heart failure and those implanted with a left ventricular assist device (LVAD). METHODS AND RESULTS: Hemodynamic measurements were obtained in 42 patients, 22 with chronic heart failure and 20 with implanted continuous flow LVAD (34 males, aged 50 ± 11 years). Measurements were performed at rest using thermodilution and IGR methods. Cardiac output derived by thermodilution and IGR were not significantly different in LVAD (4.4 ± 0.9 L/min vs 4.7 ± 0.8 L/min, P = .27) or patients with heart failure (4.4 ± 1.4 L/min vs 4.5 ± 1.3 L/min, P = .75). There was a strong relationship between thermodilution and IGR cardiac index (r = 0.81, P = .001) and stroke volume index (r = 0.75, P = .001). Bland-Altman analysis showed acceptable limits of agreement for cardiac index derived by thermodilution and IGR, namely, the mean difference (lower and upper limits of agreement) for patients with heart failure -0.002 L/min/m2 (-0.65 to 0.66 L/min/m2), and -0.14 L/min/m2 (-0.78 to 0.49 L/min/m2) for patients with LVAD. CONCLUSIONS: IGR is a valid method for estimating cardiac output and should be used in clinical practice to complement the evaluation and management of chronic heart failure and patients with an LVAD.

Current clinical application of sclera and amniotic membrane for ocular tissue bio-replacement.

To report the current clinical applications and trends of scleral and amniotic membrane use in ophthalmology. Review of annual reports from the Catalan Transplant Organization (OCATT), on scleral patch and amniotic membrane eye indications in Catalonia region (Spain) over a 6-year period from 2013 to 2018. A total of 874 scleral and 1665 amniotic membranes patches were implanted, from January 2013 to December 2018. The most frequent indication over the 6-year period for scleral patch was glaucoma surgery (77.5%), eyelid reconstruction (5.2%) and corneal or scleral ulcer (5%). Regarding amniotic membrane, corneal ulcer (26.9%), conjunctival reconstruction (23.8%) and corneal epithelial defect (22.7%) were the most common indications. During the study period, an increasing trend was found on sclera patches for eyelid reconstruction (p = 0.0032) and amniotic membrane for inflammation management (p = 0.0198). Glaucoma surgery and corneal ulcers have represented the top indications for scleral patch and amniotic membrane use, over the period, respectively. A significant trend has also been found towards eyelid reconstruction using scleral patches and amniotic membrane for anterior segment inflammation management. This evolving scenario in tissue use for ocular surgery has to be taken into consideration, especially regarding eye banks facing current and futures changes in tissue preservation, storage and indications.

Predictive factors of clinical response to treatment with anti-TNF agents in ulcerative colitis: what have we learned from our patients?

INTRODUCTION: inhibitors of tumor necrosis factor alpha (anti-TNFs) are effective drugs for the treatment of moderate-to-severe ulcerative colitis (UC). However, many patients do not respond or lose therapeutic response during follow-up. OBJECTIVES: to analyze the determining factors of clinical response to anti-TNFs in UC. METHODS: a multicenter retrospective study was performed in 79 patients with UC who started treatment with anti-TNFs between 2009 and 2015. The primary endpoint was clinical remission (pMayo index ≤ 1) at 12 months. Furthermore, remission and clinical response (final pMayo score ≤ 3) and corticoids discontinuation were assessed at three, six and 12 months. An analysis was performed to identify variables predictive of clinical response. RESULTS: at 12 months, remission and clinical response were seen in 59.2 % and 77.8 % of patients, respectively. Corticoids could be discontinued in 82.4 % of patients. At 12 months, corticoids discontinuation (< 3 months) (OR 0.06; 95 % CI: 0.01-0.24) and clinical response at six months (OR 0.008; 95 % CI: 0.001-0.053) were independent factors predictive of clinical remission. CONCLUSION: in patients with active UC on anti-TNFs, corticoid discontinuation within three months and clinical response at six months after treatment onset are predictive of clinical disease remission.

Effect of Preoperative Tricuspid and/or Mitral Regurgitation on Development of Late Right-Sided Heart Failure After Insertion of the HeartWare Left Ventricular Assist Device.

Right-sided heart failure (RHF) after left ventricular assist device implantation is a significant cause of morbidity and mortality. Although multiple predictors of early RHF have been described, information on late RHF is scarce. The aim of this study was to identify predictors of late RHF in left ventricular assist device patients. A retrospective analysis of all adult patients who underwent HeartWare-ventricular assist device implantation as a bridge to transplantation in a single-centre was performed. Late RHF was defined as RHF requiring rehospitalization after 30 days of implantation. A total of 16 (10.3%) patients from 156 implantations developed late RHF. Median time to late RHF onset was 182.5 (interquartile range 105 to 618) days. Patients developing late RHF were older at surgery. A significantly higher rate of moderate or severe tricuspid regurgitation before implantation was found in patients presenting with late RHF (81.2% vs 33.5%; p <0.001). Several echocardiographic parameters at discharge postimplant, such as significant mitral regurgitation, demonstrated a strong association with late RHF. A multivariate Cox regression analysis revealed that significant preoperative tricuspid regurgitation was the strongest predictor of late RHF (hazard ratio 5.50, 95% confidence interval [1.34 to 22.58]; p = 0.02). Significant mitral regurgitation postimplantation and older age also significantly predicted late RHF. In conclusion, preoperative significant tricuspid regurgitation and mitral regurgitation after implantation predict the occurrence of late RHF.

Initial conservative management strategy of HeartWare left ventricular assist device thrombosis with intravenous heparin or bivalirudin.

INTRODUCTION AND OBJECTIVES: Pump thrombosis is a serious left ventricular assist device complication, though there are no guidelines regarding its treatment. The main aim of this study was to describe a strategy of intravenous anticoagulation as the initial treatment in these patients and then to compare intravenous heparin with bivalirudin. METHODS: All consecutive patients who received a HeartWare left ventricular assist device from July 2009 to March 2019 were retrospectively analysed. Patients developing a pump thrombosis were selected, and treatment, outcomes and complications were recorded. RESULTS: During this period of time (116 months), 220 patients underwent HeartWare left ventricular assist device implantation and 57 developed pump thrombosis, with an incidence rate of first pump thrombosis of 0.17 events per patient-year of support (incidence rate of all episodes of pump thrombosis: 0.30 events per patient-year of support). All the patients were initially treated medically, predominantly with either intravenous heparin (n = 26) or bivalirudin (n = 16). Patients treated with bivalirudin during the first pump thrombosis episode had less subsequent re-thrombosis episodes (18.7% vs 57.7%, p < 0.05). In addition, percentage time in therapeutic range was greater for bivalirudin compared with heparin (68.5% ± 16.9% vs 37.4% ± 31.0%, p < 0.01). During the first pump thrombosis episode, 26.3% of the patients needed surgery (left ventricular assist device exchange (n = 8), transplant (n = 6) or decommissioning (n = 1)). The overall survival at 1 year was 61.4%, and there was no significant difference in survival. CONCLUSION: Left ventricular assist device thrombosis is a serious life-threatening complication; hence, we propose an initial conservative management of pump thrombosis with enhanced intravenous anticoagulation with either intravenous heparin or bivalirudin, with surgery reserved for refractory cases.

Higroma quístico fetal / Fetal cystic hygroma

El higroma quístico congénito o linfangioma es un tumor del sistema linfático, es de origen embrionario y se origina por la obstrucción del drenaje de los sacos linfáticos. Su localización en orden de frecuencia es en las regiones cervical, axilar, intraperitoneal e inguinal, y muy raro como alteración única en el mediastino anterior. Paciente de 32 años de edad, con embarazo 16 sem ± 6 días y reporte de ecografía: Embarazo de 15 sem ± 20 días, normohidramnia, higroma quístico, Ausencia de hueso nasal además de una comunicación interventricular. Paciente en sala de legrado bajo sedación profunda, se obtiene producto de sexo masculino con alteraciones faciales y aumento de volumen en región cervical. Podemos concluir que, el control prenatal es importante realizar para obtener un diagnóstico precoz con examen ecográfico seriado, estudio genético, ecocardiografía fetal y para dar tratamiento quirúrgico es necesario conformar un equipo multidisciplinario.(AU)
