RESUMO

The purpose of this study was to conduct a literature review to examine micronutrient deficiencies in laparoscopic sleeve gastrectomy. We conducted a literature review using PubMed and Cochrane databases to examine micronutrient deficiencies in SG patients in order to identify trends and find consistency in recommendations. Seventeen articles were identified that met the defined criteria. Iron, vitamin B12 and vitamin D were the primary micronutrients evaluated. Results demonstrate the need for consistent iron and B12 supplementation, in addition to a multivitamin, while vitamin D supplementation may not be necessary. Additional prospective studies to establish a clearer picture of micronutrient deficiencies post-SG are needed.

RESUMO

INTRODUCTION: There is scarce information about the clinical profile and prognosis of acute heart failure (AHF) at the extreme ranges of age. We aimed to evaluate the 1-year death (all-cause mortality and HF-death) and HF-rehospitalizations of patients ≥85 years admitted for AHF. METHODS: We prospectively evaluated a cohort of 3054 patients admitted with AHF from 2007 to 2018 in a third-level center. Age was categorized per 10-year categories (<65 years; 65-74 years, 75-84 years, and ≥85 years). The risk of mortality and HF-rehospitalizations across age categories was evaluated with Cox regression analysis and Cox regression adapted for competing events as appropriate. RESULTS: The mean age was 73.6 ± 11.2 years, 48.9% were female, and 52.8% had preserved left ventricular ejection fraction (HFpEF). A total of 414 (13.6%) patients were ≥85 years. Among this group of age, female sex and HFpEF phenotype were more frequent. At 1-year follow-up 667 all-cause deaths (22,1%), 311 HF-deaths (10.1%) and 693 HF-hospitalizations (22,7%) were recorded. After multivariable adjustment, and compared to patients <65 years, a stepwise increased risk of all-cause mortality and HF-death was found for each decade increase in age, especially for patients ≥85 years (HR=3.47; 95% CI: 2.49 - 4.84, p<0.001, HR=3.31; 95% CI: 1.95 - 5.63; p<0.001, respectively). This subgroup of patients also showed an increased risk of HF-rehospitalization (HR=1.58; 95% CI: 1.16 - 2.16, p=0.004). CONCLUSIONS: Super elderly patients admitted with AHF showed a dramatically increased risk of 1-year death. This subset of patients also shown an increased risk of 1-year HF-readmission.

RESUMO

Right ventricular dysfunction (RVD) parameters are increasingly important features in heart failure with preserved ejection fraction (HFpEF). We sought to evaluate the prognostic impact of a progressive RVD staging system by combining the tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (TAPSE/PASP) ratio with functional tricuspid regurgitation (TR) severity. We prospectively included 1355 consecutive HFpEF patients discharged for acute heart failure (HF). Of them, in 471 (34.7%) patients, PASP could not be accurately measured, leaving the final sample size to be 884 patients. Patients were categorized as Stage 1: TAPSE/PASP ≥ 0.36 without significant TR; stage 2: TAPSE/PASP ≥ 0.36 with significant TR; stage 3: TAPSE/PASP < 0.36 without significant TR; and stage 4: TAPSE/PASP < 0.36 with significant TR. By the 1 year follow-up, 207 (23.4%) patients had died. We found a significant and graded association between RVD stages and mortality rates (15.8%, 25%, 31.2%, and 45.4% from stage 1 to stage 4, respectively; log-rank test, p < 0.001). After multivariable adjustment, and compared to stage 1, stages 3 and 4 were independently associated with mortality risk (HR: 1.8219; 95% CI 1.308-2.538; p < 0.001 and HR = 2.2632; 95% CI 1.540-3.325; p < 0.001, respectively). A RVD staging system, integrating TAPSE/PASP and TR, provides a comprehensive and widely available tool for risk stratification in HFpEF.

RESUMO

BACKGROUND: Metabolic surgery is the most effective method for weight loss in the long-term treatment of morbid obesity and its comorbidities. The primary aim of this study was to examine factors associated with percent total weight loss (%TWL) after metabolic surgery among an ethnically diverse sample of patients. METHODS: A retrospective review was performed on 1012 patients who underwent either a sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) at our institution between January 2008 and June 2015. RESULTS: African Americans had a lower %TWL than non-Hispanic/Latino Whites at 6, 9, 12, 18, and 48 months. At all timeframes, there was a negative association between pre-surgery TWL and %TWL after surgery. Female sex was negatively associated with %TWL at 3 months only. Higher initial BMI was also associated with greater post-operative %TWL at 18, 24 and 36 months. Older patients had lower %TWL at 6, 9, 12 and 24 months post-surgery. Patients who received RYGB had greater %TWL than those who received SG at 3, 6, 9, 12, 24 and 36 months. CONCLUSIONS: African Americans had a lower %TWL than non-Hispanic/Latino Whites at most time points; there were no other significant race/ethnicity or sex differences. BMI (greater initial BMI), age (lower) and RYGB were associated with a greater post-operative %TWL at certain post-surgery follow-up time points. A limitation of this study is that there was missing data at a number of time points due to lack of attendance at certain follow-up visits.

RESUMO

Introducción y objetivos: Los pacientes con insuficiencia cardiaca en tratamiento con antagonistas de la vitamina K (AVK) por fibrilación auricular no valvular (FANV) a menudo presentan valores alterados de la razón internacional normalizada (INR). El objetivo es evaluar la asociación entre la INR al ingreso por insuficiencia cardiaca y el riesgo de mortalidad en el seguimiento. Métodos: Estudio observacional retrospectivo en el que se evaluó la INR al ingreso de 1.137 pacientes consecutivos con insuficiencia cardiaca aguda en tratamiento con AVK por FANV. Esta se categorizó en: INR en rango óptimo (INR = 2-3, n = 210), infraterapéutica (INR < 2, n = 660) o supraterapéutica (INR > 3, n = 267). La asociación independiente entre INR y mortalidad se evaluó mediante cálculo restringido de las diferencias en tiempos de supervivencia media, dado que la INR no cumple la condición de proporcionalidad de riesgos de mortalidad. Resultados: Tras una mediana de 2,15 [0,71-4,29] años, fallecieron 495 pacientes (43,5%). En el análisis multivariable, tanto la INR infraterapéutica como la supraterapéutica se asociaron con un mayor riesgo de mortalidad, con unas diferencias en tiempos de supervivencia media a 5 años de -0,50 años (IC95%,-0,77 a -0,23; p < 0,001) y -0,40 años (IC95%, -0,70 a -0,11; p = 0,007) con respecto a los pacientes con INR 2-3. Conclusiones: La INR fuera de rango óptimo al ingreso de los pacientes con insuficiencia cardiaca aguda en tratamiento con AVK por FANV se asocia de manera independiente con un mayor riesgo de mortalidad en el seguimiento a largo plazo


Introduction and objectives: Heart failure patients with nonvalvular atrial fibrillation (NVAF) on treatment with vitamin K antagonists (VKA) often have suboptimal international normalized ratio (INR) values. Our aim was to evaluate the association between INR values at admission due to acute heart failure and mortality risk during follow-up. Methods: In this observational study, we retrospectively assessed INR on admission in 1137 consecutive patients with acute heart failure and NVAF who were receiving VKA treatment. INR was categorized into optimal values (INR = 2-3, n = 210), subtherapeutic (INR < 2, n = 660), and supratherapeutic (INR > 3, n = 267). Because INR did not meet the proportional hazards assumption for mortality, restricted mean survival time differences were used to evaluate the association among INR categories and the risk of all-cause mortality. Results: During a median [interquartile range] follow-up of 2.15 years [0.71-4.29], 495 (43.5%) patients died. On multivariable analysis, both patients with subtherapeutic and supratherapeutic INR showed higher risks of all-cause mortality, as evidenced by their restricted mean survival time differences at 5 years' follow-up: -0.50; 95%CI, -0.77 to -0.23 years; P < .001; and -0.40; 95%CI, -0.70 to -0.11 years; P = .007, respectively, compared with INR 2-3. Conclusions: In acute heart failure patients on treatment with VKA for NVAF, INR values out of normal range at admission were independently associated with a higher long-term mortality risk

RESUMO

Background: Various technical improvements have decreased the morbidity and mortality after pancreaticoduodenectomy. However, postoperative pancreatic fistula (POPF) is the most feared complication, and the ideal technique for pancreatic reconstruction is undetermined. The aim of this study was to identify the risk factors and incidence of POPF with different types of pancreatic stump management after robot-assisted pancreaticoduodenectomy (RAPD). Materials and Methods: This study is a retrospective review of consecutive patients who underwent RAPD at the University of Illinois Hospital and Health Sciences System between September 2007 and January 2016. The cohort was divided based on the type of pancreatic stump management: pancreatic duct occlusion with cyanoacrylate glue (CG), pancreaticojejunostomy (PJ), posterior pancreaticogastrostomy (PPG), and transgastric pancreaticogastrostomy (TPG). Results: The cohort included 69 patients: pancreatic duct occlusion with CG (n = 18), PJ (n = 12), PPG (n = 11), and TPG (n = 28). Pancreatic duct diameter < 3 mm and duct occlusion with CG were identified as risk factors for POPF (p < 0.05). The incidence of POPF was lower when TPG and PJ were performed (p < 0.001). Conclusions: Reconstruction with PJ and TPG had better results compared to pancreatic duct occlusion with CG and PPG. However, TPG was the technique of choice and showed comparable results to PJ.

RESUMO

Introducción y objetivos: No se dispone de tratamientos farmacológicos que demuestren reducir la morbimortalidad asociada en pacientes con insuficiencia cardiaca y función sistólica conservada (IC-FEc). El objetivo del presente estudio fue evaluar si en pacientes con IC-FEc, el entrenamiento de la musculatura inspiratoria (EMI), la electroestimulación muscular funcional (EMF) o la combinación de ambas (EMI + EMF) puede mejorar la capacidad funcional, calidad de vida, parámetros de disfunción diastólica o biomarcadores a las 12 y 24 semanas. Métodos: Un total de 61 pacientes estables con IC-FEc (clase funcional de la New York Heart Association II-III) se aleatorizaron (1:1:1:1) a recibir un programa de 12 semanas de EMI, EMF, o EMI + EMF frente a tratamiento médico estándar (control). El objetivo primario fue evaluar el cambio en el consumo máximo de oxígeno. Los objetivos secundarios fueron los cambios en la calidad de vida, parámetros ecocardiográficos y biomarcadores. Se utilizó un modelo lineal mixto para comparar los cambios entre los diferentes grupos. Resultados: La edad media fue 74 +/- 9 años y la proporción de mujeres fue del 58%. El test de consumo máximo de oxígeno fue de 9,9 +/- 2,5ml/min/kg. A las 12 semanas, con respecto al grupo control, el incremento medio de consumo máximo de oxígeno fue de 2,98, 2,93 y 2,47 para EMI, EMF y EMI + EMF, respectivamente (p < 0,001). Este incremento se mantuvo a las 24 semanas (1,95, 2,08 y 1,56, respectivamente; p < 0,001). Resultados similares se observaron en la puntuación del cuestionario de calidad de vida (p < 0,001). Conclusiones: En los pacientes con IC-FEc e importante reducción de la capacidad funcional, tanto el EMI como la EMF se asocian con una marcada mejoría de la capacidad funcional y la calidad de vida


Introduction and objectives: Despite the prevalence of heart failure with preserved ejection fraction (HFpEF), there is currently no evidence-based effective therapy for this disease. This study sought to evaluate whether inspiratory muscle training (IMT), functional electrical stimulation (FES), or a combination of both (IMT + FES) improves 12- and 24-week exercise capacity as well as left ventricular diastolic function, biomarker profile, and quality of life in HFpEF. Methods: A total of 61 stable symptomatic patients (New York Heart Association functional class II-III) with HFpEF were randomized (1:1:1:1) to receive a 12-week program of IMT, FES, or IMT + FES vs usual care. The primary endpoint of the study was to evaluate change in peak exercise oxygen uptake at 12 and 24 weeks. Secondary endpoints were changes in quality of life, echocardiogram parameters, and prognostic biomarkers. We used a mixed-effects model for repeated-measures to compare endpoints changes. Results: Mean age and peak exercise oxygen uptake were 74 +/- 9 years and 9.9 +/- 2.5mL/min/kg, respectively. The proportion of women was 58%. At 12 weeks, the mean increase in peak exercise oxygen uptake (mL/kg/min) compared with usual care was 2.98, 2.93, and 2.47 for IMT, FES, and IMT + FES, respectively (P < .001) and this beneficial effect persisted after 24 weeks (1.95, 2.08, and 1.56; P < .001). Significant increases in quality of life scores were found at 12 weeks (P < .001). No other changes were found. Conclusions: In HFpEF patients with low aerobic capacity, IMT and FES were associated with a significant improvement in exercise capacity and quality of life

RESUMO

AIMS: Optimal diuretic treatment of patients with refractory congestive heart failure (CHF) remains to be elucidated. In this work, we aimed to evaluate the serial changes of functional class and surrogates of fluid overload (weight and antigen carbohydrate 125) after addition of oral acetazolamide in patients with refractory CHF. Likewise, serial changes in renal function, serum electrolytes and pH were evaluated. METHOD: This is an observational retrospective study in which 25 ambulatory patients with refractory CHF that received acetazolamide in addition to standard intensive diuretic strategy were evaluated. Longitudinal assessment of New York Heart Association (NYHA) functional class and biomarkers was analyzed using joint modelling of longitudinal and survival data. RESULTS: All patients showed NYHA class III/IV at baseline. After prescription of acetazolamide, a total of 125 outpatient visits were recorded [median visits per patient: 6 (IQR = 3-7)] during a median follow-up of 152 days (IQR = 80-353). A significant decrease in NYHA class, weight, and antigen carbohydrate 125 was observed. On the other hand, estimated glomerular filtration rate increased over time. No significant changes in systolic blood pressure, serum sodium, potassium, amino-terminal pro-brain natriuretic peptide, and pH occurred. CONCLUSION: In a cohort of patients with refractory CHF treated with an intensive diuretic treatment, the addition of acetazolamide was associated with improvement in functional class and surrogates of fluid overload.

RESUMO

BACKGROUND: A number of technical improvements regarding the pancreatic anastomosis have decreased the morbidity and mortality after pancreaticoduodenectomy. However, postoperative pancreatic fistula (POPF) remains is the most feared complication, and the ideal technique for pancreatic reconstruction is undetermined. MATERIALS AND METHODS: This study is a retrospective review of a prospectively maintained database. Data were collected from all consecutive robot-assisted pancreaticoduodenectomies (RAPD), performed by a single surgeon, at the University of Illinois Hospital & Health Sciences System, between September 2007 and January 2016. RESULTS: A total of 28 consecutive patients (16 male and 12 female) who underwent a RAPD were included in this study. Patients had a mean age and mean BMI of 61.5 years (SD = 12.3) and 27 kg/m2 (SD = 4.9), respectively. The mean operative time was 468.2 min (SD = 73.7) and the average estimated blood loss was 216.1 ml (SD = 113.1). The mean length of hospitalization was 13.1 days (SD = 5.4). There was no clinically significant POPF registered. CONCLUSION: Trans-gastric pancreaticogastrostomy (TPG) represents a valid and feasible option as a pancreatic digestive reconstruction during RAPD. Initial results showed decreased incidence of POPF with an increased risk of postoperative bleeding. Our experience suggests that TPG might be safer than pancreaticojejunostomy (PJ); further studies are needed in order to confirm.

RESUMO

Introducción y objetivos: El tratamiento óptimo de pacientes con insuficiencia cardiaca aguda (ICA) y síndrome cardiorrenal tipo 1 (SCR-1) no está bien definido. La hipoperfusión arterial y la congestión venosa tienen un papel fundamental en la fisiopatología del SCR-1. El antígeno carbohidrato 125 (CA125) ha emergido como marcador indirecto de sobrecarga de volumen en la ICA. El objetivo de este estudio es evaluar la utilidad del CA125 para el ajuste del tratamiento diurético de pacientes con SCR-1. Métodos: Ensayo clínico multicéntrico, abierto y paralelo, que incluye a pacientes con ICA y creatinina ≥ 1,4 mg/dl al ingreso, aleatorizados a: a) estrategia convencional: titulación basada en la evaluación clínica y bioquímica habitual, o b) estrategia basada en CA125: dosis altas de diuréticos si CA125 > 35 U/ml y bajas en caso contrario. El objetivo principal es el cambio en la función renal a las 24 y las 72 h tras el comienzo del tratamiento. Como objetivos secundarios: a) cambios clínicos y bioquímicos a las 24 y las 72 h, y b) cambios en la función renal y eventos clínicos mayores a 30 días. Resultados: Los resultados de este estudio aportarán datos relevantes sobre la utilidad del CA125 para guiar el tratamiento diurético en el SCR-1. Además, permitirá ampliar el conocimiento de la fisiopatología de esta compleja entidad clínica. Conclusiones: La hipótesis del presente estudio es que las concentraciones de CA125 aumentadas pueden identificar a una población de pacientes con SCR-1 para quienes una estrategia diurética más intensa puede ser beneficiosa. Por el contrario, las concentraciones bajas de esta glucoproteína seleccionarían a los pacientes para los que serían perjudiciales las dosis altas de diuréticos (AU)


Introduction and objectives: The optimal treatment of patients with acute heart failure (AHF) and cardiorenal syndrome type 1 (CRS-1) is far from being well-defined. Arterial hypoperfusion in concert with venous congestion plays a crucial role in the pathophysiology of CRS-I. Plasma carbohydrate antigen 125 (CA125) has emerged as a surrogate of fluid overload in AHF. The aim of this study was to evaluate the clinical usefulness of CA125 for tailoring the intensity of diuretic therapy in patients with CRS-1. Methods: Multicenter, open-label, parallel clinical trial, in which patients with AHF and serum creatinine ≥ 1.4 mg/dL on admission will be randomized to: a) standard diuretic strategy: titration-based on conventional clinical and biochemical evaluation, or b) diuretic strategy based on CA125: high dose if CA125 > 35 U/mL, and low doses otherwise. The main endpoint will be renal function changes at 24 and 72 hours after therapy initiation. Secondary endpoints will include: a) clinical and biochemical changes at 24 and 72 hours, and b) renal function changes and major clinical events at 30 days. Results: The results of this study will add important knowledge on the usefulness of CA125 for guiding diuretic treatment in CRS-1. In addition, it will pave the way toward a better knowledge of the pathophysiology of this challenging situation. Conclusions: We hypothesize that higher levels of CA125 will identify a patient population with CRS-1 who could benefit from the use of a more intense diuretic strategy. Conversely, low levels of this glycoprotein could select those patients who would be harmed by high diuretic doses (AU)

RESUMO

BACKGROUND: Abdominal lipectomy after bariatric surgery is recommended because of residual excess skin resulting in difficulty with maintaining hygiene, recurrent infections, and functional impairment, interfering with daily activities. There is a dearth of literature examining weight loss outcomes in patients undergoing abdominal lipectomy post sleeve gastrectomy (SG). The purpose of this study was to examine whether post-SG patients who received abdominal lipectomy achieved greater percent excess weight loss (%EWL) than post-SG patients who did not receive abdominal lipectomy. METHODS: Retrospective study of patients who underwent minimally invasive SG at the University of Illinois Hospital and Health Sciences System from March 2008 to June 2015 was conducted. The cohort was divided into 2 groups: patients who underwent abdominal lipectomy after SG (PS-SG) and patients who underwent SG alone (SG). Demographics, comorbidities, and %EWL were examined. RESULTS: Twenty-nine patients were included in the PS-SG group versus 287 patients in the SG group. Significant differences were found in %EWL at 24 (P < 0.0001), 36 (P < 0.005), and more than 36 months (P < 0.005) follow-up between groups, with a greater %EWL in patients in the PS-SG group versus the SG group. CONCLUSIONS: This preliminary study revealed that patients in the PS-SG group achieved greater %EWL than patients with SG alone. Although larger studies are needed, this study supports using abdominal lipectomy as an adjunctive procedure to assist with long-term weight loss as part of the overall treatment of bariatric surgery patients.

RESUMO

INTRODUCTION AND OBJECTIVES: The optimal treatment of patients with acute heart failure (AHF) and cardiorenal syndrome type 1 (CRS-1) is far from being well-defined. Arterial hypoperfusion in concert with venous congestion plays a crucial role in the pathophysiology of CRS-I. Plasma carbohydrate antigen 125 (CA125) has emerged as a surrogate of fluid overload in AHF. The aim of this study was to evaluate the clinical usefulness of CA125 for tailoring the intensity of diuretic therapy in patients with CRS-1. METHODS: Multicenter, open-label, parallel clinical trial, in which patients with AHF and serum creatinine ≥ 1.4mg/dL on admission will be randomized to: a) standard diuretic strategy: titration-based on conventional clinical and biochemical evaluation, or b) diuretic strategy based on CA125: high dose if CA125 > 35 U/mL, and low doses otherwise. The main endpoint will be renal function changes at 24 and 72hours after therapy initiation. Secondary endpoints will include: a) clinical and biochemical changes at 24 and 72hours, and b) renal function changes and major clinical events at 30 days. RESULTS: The results of this study will add important knowledge on the usefulness of CA125 for guiding diuretic treatment in CRS-1. In addition, it will pave the way toward a better knowledge of the pathophysiology of this challenging situation. CONCLUSIONS: We hypothesize that higher levels of CA125 will identify a patient population with CRS-1 who could benefit from the use of a more intense diuretic strategy. Conversely, low levels of this glycoprotein could select those patients who would be harmed by high diuretic doses.

RESUMO

BACKGROUND: One of the perceived major drawbacks of minimally invasive techniques has always been its cost. This is especially true for the robotic approach and is one of the main reasons that has prevented its wider acceptance among hospitals and surgeons. The aim of our study was to evaluate the clinical outcomes and economic impact of robotic and open liver surgery in a single institution. METHODS: Sixty-eight robotic and 55 open hepatectomies were performed at our institution between January 1, 2009 and December 31, 2013. Demographics, perioperative data, and postoperative outcomes were collected and compared between the two groups. An independent company performed the financial analysis. The economic parameters comprised direct variable costs, direct fixed costs, and indirect costs. RESULTS: Mean estimated blood loss was significantly less in the robotic group (438 versus 727.8 mL; P = .038). Overall morbidity was significantly lower in the robotic group (22% versus 40%; P = .047). Clavien III/IV complications were also lower, with 4.4% in the robotic versus 16.3% in the open group (P = .043). The length of stay in the intensive care unit (ICU) was shorter for patients who underwent a robotic procedure (2.1 versus 3.3 days; P = .004). The average total cost, including readmissions, was $37,518 for robotic surgery and $41,948 for open technique. CONCLUSIONS: Robotic liver resections had less overall morbidity, ICU, and hospital stay. This translates into decreased average costs for robotic surgery. These procedures are financially comparable to open resections and do not represent a financial burden to the hospital.

RESUMO

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) was a popular procedure in the USA and Europe in the past decade. However, its use has currently declined. Band erosion (BE) is a rare complication after LAGB with a reported incidence rate of 1.46 %. Controversies exist regarding the management, approach and timing for the band removal. The aim of this study is to describe the rate, clinical presentation and perioperative outcomes of BEs at our institution and provide overall recommendations regarding the diagnosis and management of BE. MATERIALS AND METHODS: This study is a single-center, retrospective review of a prospectively maintained database. Data were collected from all consecutive patients who underwent a LAGB and band revisional surgeries at the University of Illinois Hospital and Health Sciences System from December 2008 to September 2015. We identified patients who underwent gastric band removal due to a BE and analyzed their outcomes. RESULTS: A total of 576 LAGBs were performed at our institution. Nine patients underwent surgery for BE at our hospital. The average time between the primary surgery and the removal of the band was 68.5 (42.9) months. Abdominal pain, nausea and/or vomiting were the most frequently mentioned symptoms. In all patients, a minimally invasive approach was used to remove the band. The mean length of hospitalization was 2.6 (1.1) days. The only complication was a pneumonia (n = 1). CONCLUSIONS: BE is one of the most severe complications of LAGB. The minimally invasive approach provided us with the opportunity to repair the fistula, and it was associated with a prompt recovery with very little morbidity. In general, it is recommended that the band be removed at the time of the diagnosis of the BE. Endoscopic band removal can be utilized with patients who have a more advanced BE and migration into the gastric lumen.

RESUMO

BACKGROUND: The increasing prevalence of obesity has necessitated the increasing use of bariatric surgery in the adolescent population. Outcomes following laparoscopic sleeve gastrectomy (LSG) among adolescents, however, have not been well-studied. We report outcomes following LSG as a first-line surgical therapy in patients under 21years of age. METHODS: All patients who underwent LSG as a primary surgical option for morbid obesity were identified at the University of Illinois at Chicago between 2006 and 2014. Standard clinicopathologic and outcomes data were recorded. RESULTS: We identified 18 patients (13 females, 5 males) who underwent LSG. Mean patient age was 17.8±1.7years. Mean BMI among all patients was 48.6±7.2kg/m2 and did not differ by gender (P=0.68). One patient (5.6%) experienced a 30-day perioperative complication (pulmonary embolism). Median LOS following LSG was 3days (IQR: 2, 3). 2 patients (11.1%) were readmitted within 30-days because of feeding intolerance that resolved without invasive intervention. At a median follow-up of 10.6 (range: 0-38) months, percent excess weight loss (%EWL) among all patients was 35.6%. Among patients with at least 2years follow-up (n=3), %EWL was 50.2%. CONCLUSIONS: Laparoscopic sleeve gastrectomy in morbidly obese adolescents is a safe and feasible option. Short- and long-term weight loss appears to be successful following LSG. As such, LSG should be strongly considered as a primary surgical treatment option for all morbidly obese adolescents. LEVEL OF EVIDENCE: Level IV.

RESUMO

Heart failure with preserved ejection fraction (HFpEF) has become the most prevalent form of heart failure in developed countries. Regrettably, there is no evidence-based effective therapy for HFpEF. We seek to evaluate whether inspiratory muscle training, functional electrical stimulation, or a combination of both can improve exercise capacity as well as left ventricular diastolic function, biomarker profile, quality of life (QoL), and prognosis in patients with HFpEF. A total of 60 stable symptomatic patients with HFpEF (New York Heart Association class II-III/IV) will be randomized (1:1:1:1) to receive a 12-week program of inspiratory muscle training, functional electrical stimulation, a combination of both, or standard care alone. The primary endpoint of the study is change in peak exercise oxygen uptake; secondary endpoints are changes in QoL, echocardiogram parameters, and prognostic biomarkers. As of March 21, 2016, thirty patients have been enrolled. Searching for novel therapies that improve QoL and autonomy in the elderly with HFpEF has become a health care priority. We believe that this study will add important knowledge about the potential utility of 2 simple and feasible physical interventions for the treatment of advanced HFpEF.

RESUMO

BACKGROUND: The appropriate approach, in the case of an aberrant right hepatic artery (RHA) during open pancreaticoduodenectomy (PD), has already been established. The aim of our study is to analyze the short-term surgical and oncological outcomes after robotic PD in patients with anatomical variants, with a special focus on totally replaced RHA. METHODS: This study is a retrospective review of a prospectively maintained database collected from consecutive patients who underwent robotic PD at the University of Illinois Hospital and Health Sciences System between September 2007 and April 2015. RESULTS: Fifteen patients (20.5%) presented with an anatomical variation of the RHA. Four patients had an accessory RHA and 11 had a totally replaced RHA. 50% of the cases were recognized by the radiologist preoperatively. There were no significant differences in the pre- and postoperative outcomes of the aberrant and normal RHA group. The mean number of harvested lymph nodes in the totally replaced RHA group was 22.8 ± 11.4. The rate of positive resection margins was 0% in the totally replaced RHA group and 9% in the normal RHA group. CONCLUSIONS: This study suggests that robotic PD has no negative impact on surgical and oncological outcomes in patients with a totally replaced RHA.
