ABSTRACT
PURPOSE: To compare short-term and medium-term results of superior rectal artery embolization versus surgical hemorrhoidectomy in the treatment of patients with hemorrhoidal disease. MATERIAL AND METHODS: This study was a prospective randomized clinical trial following 33 patients with symptomatic hemorrhoidal disease Grades 2 and 3 who were randomly assigned to 2 different groups: the superior rectal artery embolization group (n = 15) and Ferguson closed hemorrhoidectomy surgical group (n = 14). Four patients were excluded from the analysis. Pain using the visual analog scale and the use of analgesics were evaluated 3 times daily during the first 7 days of the postoperative period. Recurrent symptoms and satisfaction with treatment were also evaluated in the subsequent first, third, sixth, and twelfth months. RESULTS: The mean pain during the first bowel movement after the procedure was 6.08 ± 4.41 in the surgery group and 0 in the embolization group (P = .001). The mean use of pain medication was higher in the surgery group (28.92 doses ± 15.78 vs 2.4 doses ± 5.21; P < .001). In the embolization group, the most prevalent preprocedural symptom was bleeding in 14 patients, with complete improvement in 12 (83.3%) patients. Mucus, skin tag, and pruritus were symptoms that showed little improvement in both groups. The frequency of symptoms (bleeding, pain, prolapse, and pruritus) was similar between the groups at 12 months (P = .691). No severe adverse events were observed in both groups. CONCLUSIONS: Despite no difference in outcomes, embolization of the superior rectal arteries for the treatment of hemorrhoidal disease showed pain levels lower than those observed after surgical treatment.

OBJECTIVE: We aim to examine the effect of benchmarking on quality-of-care metrics in patients presenting with ST-elevation myocardial infarction (STEMI) through the implementation of the American College of Cardiology (ACC) National Cardiovascular Data Registry (NCDR) ACTION Registry. DESIGN: From January 2005 to December 2017, 712 patients underwent primary percutaneous coronary intervention PCI-499 before NCDR ACTION Registry implementation (prior to 2013) and 213 after implementation. SETTING: STEMI. PARTICIPANTS: 712 patients. INTERVENTION(S): Primary PCI. MAIN OUTCOME MEASURE(S): We examined hospital performance for the quality indicators in processes and outcomes of the management of patients presenting with STEMI. Outcome measures include door-to-balloon time (DBT), antiplatelet therapy and anti-ischemic drugs prescribed at discharge from pre-NCDR ACTION Registry to post-implementation. RESULTS: There was improvement in DBT, decreasing from 94 min in 2012 (before NCDR adoption) to reach a median of 47 min in 2017 (Ptrend < 0.001). The percentage of cases with the optimal DBT of < 90 min increased from 55.8% before to 90.1% after the implementation of the NCDR ACTION Registry (Ptrend < 0.001). The rate of aspirin (90.3-100%, P < 0.001), P2Y12 inhibitor (70.1-78.4%, P = 0.02), beta-blocker (76.8-100%, P < 0.001) and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (60.1-99.5%, P < 0.001) prescribed at discharge increased from pre-NCDR ACTION Registry to post-implementation. Adjusted mortality before and after NCDR ACTION Registry implementation showed significant change (from 9.04 to 5.92%; P = 0.027). CONCLUSIONS: The introduction of the ACC NCDR ACTION Registry led to incremental gains in the quality in STEMI management through the benchmarking of process of care and clinical outcomes, achieving reduced DBT, improving guideline-directed medication adherence and increasing patient safety, treatment efficacy and survival.

OBJECTIVES: This study aimed to compare gender-related differences in outcomes of patients undergoing TAVI over a long-term follow-up period. BACKGROUND: Transcatheter aortic valve implantation (TAVI) has been considered the standard therapy for patients with inoperable or high-risk symptomatic aortic stenosis. The influence of gender-related differences in outcomes of patients undergoing TAVI is currently on debate. METHODS: From January 2008 to January 2015, 819 patients (49% men) underwent TAVI and were included in a multicenter Brazilian registry. Patients were followed-up and clinical outcomes were evaluated according to the updated Valve Academic Research Consortium-2 criteria. RESULTS: Mean follow-up was 497 ± 478 days. Compared with women, men had a lower rate of major or life-threatening bleeding (12.0% vs. 20.6%; HR = 0.57 [95CI% 0.40-0.81]; P = 0.001), and major vascular complications (6% vs. 11.7%; HR = 0.50 [95CI% 0.31-0.82]; P = 0.004). At 30 days, all-cause mortality was lower in men than in women (6.5% vs. 11.5%; P = 0.013), however, cumulative all-cause mortality was similar between groups (25.9% vs. 29.7%, men and women, respectively, HR = 0.92 [95CI% 0.71-1.19]; P = 0.52) over the entire follow-up period. By adjusted Cox regression model, renal function, diabetes, peripheral artery disease, and chronic obstructive pulmonary disease (COPD) remained independently predictors of all-cause mortality. CONCLUSIONS: In this large-scale study evaluating patients undergoing TAVI, 30-day mortality was higher among women than men driven by significant higher rates of major or life-threatening bleeding and major vascular complications. However, all-cause mortality on long-term follow-up was similar between groups. © 2016 Wiley Periodicals, Inc.

OBJECTIVES: Elevated B-type natriuretic peptide (BNP) levels following acute myocardial infarction (AMI) are associated with adverse outcomes. The role of serial BNP monitoring after AMI has been poorly investigated. We aimed to evaluate the prognostic value of in-hospital serial BNP measurements in AMI patients. METHODS: Patients with AMI (n=1,924) were retrospectively evaluated. We selected patients with at least 2 in-hospital BNP measurements. The association between in-hospital mortality and BNP measurements (earliest, highest follow-up and the variation between measurements) were tested in multivariate models. RESULTS: Serial BNP levels were determined in 176 patients. Compared to the rest of the population, these patients were older and had higher mortality rates. In the adjusted models, only the highest follow-up BNP remained associated with in-hospital death (odds ratio 1.06; 95% confidence interval, CI, 1.01-1.15; p=0.014). Receiver-operating characteristic curve analysis demonstrated that the highest follow-up BNP was the best predictor of in-hospital death (area under the curve=0.75; 95% CI 0.64-0.86). CONCLUSIONS: Serial BNP monitoring was performed in a high-risk subgroup of AMI patients. The highest follow-up BNP was a better predictor of short-term death than the baseline and in-hospital variation values. In AMI patients, a later in-hospital BNP assessment may be more useful than an early measurement.

BACKGROUND AND AIM OF THE STUDY: The natriuretic peptides, brain natriuretic peptide (BNP) and its N-terminal prohormone (NT-proBNP), can be used as diagnostic and prognostic markers for aortic stenosis (AS). However, the association between BNP, NT-proBNP, and long-term clinical outcomes in patients with severe AS remains uncertain. METHODS: A total of 64 patients with severe AS was prospectively enrolled into the study, and underwent clinical and echocardiographic assessments at baseline. Blood samples were drawn for plasma BNP and NT-proBNP analyses. The primary outcome was death from any cause, through a six-year follow up period. Cox proportional hazards modeling was used to examine the association between natriuretic peptides and long-term mortality, adjusting for important clinical factors. RESULTS: During a mean period of 1,520 +/- 681 days, 51 patients (80%) were submitted to aortic valve replacement, and 13 patients (20%) were medically managed without surgical interventions. Mortality rates were 13.7% in the surgical group and 62% in the medically managed group (p < 0.001). Patients with higher plasma BNP (> 135 pg/ml) and NT-proBNP (> 1,150 pg/ml) levels at baseline had a greater risk of long-term mortality (hazard ratio [HR] 3.2, 95% confidence interval [CI] 1.1-9.1; HR 4.3, 95% CI 1.4-13.5, respectively). After adjusting for important covariates, both BNP and NT-proBNP remained independently associated with long-term mortality (HR 2.9, 95% CI 1.5-5.7; HR 1.8, 95% CI 1.1-3.1, respectively). CONCLUSION: In patients with severe AS, plasma BNP and NT-proBNP levels were associated with long-term mortality. The use of these biomarkers to guide treatment might represent an interesting approach that deserves further evaluation.

OBJECTIVES: Value-based healthcare (VBHC) is a health system reform gradually being implemented in health systems worldwide. A previous national-level survey has shown that Latin American countries were in the early stages of alignment with VBHC. Data at the healthcare provider organisations (HPOs) level are lacking. This study aim was to investigate how HPOs in five Latin American countries are implementing VBHC. DESIGN: Mixed-methods research was conducted using online questionnaire, semistructured interviews based on selected elements of the value agenda (from December 2018 to June 2020), analyses of aggregated data and documents. Qualitative analysis was performed using NVivo QSR International, 1.6.1 (4830). Quantitative analysis used Fisher's exact test. Univariate analysis was used to compare organisations in relation to the implementation of VBHC initiatives. A p≤0.05 was considered significant. PARTICIPANTS: Top and middle-level executives from 70 HPOs from Argentina, Brazil, Chile, Colombia and Mexico. RESULTS: The definition of VBHC varied across participating organisations. Although the value equation had been cited by 24% of participants, its composition differed in most case from the original Equation. Most VBHC initiatives were related to care delivery organisation (56.9%) and outcomes measurement (22.4%) but in most cases, integrated practice unit features had not been fully developed and outcome data was not used to guide improvement. Information, stakeholders buy-in, compensation and fragmented care delivery were the most cited challenges to VBHC implementation. Fee-for-service predominated, although one-third of organisations were experimenting with alternative payment models. CONCLUSIONS: A wide variation in the definition and level of VBHC implementation existed across organisations. Our finding suggests investments in information systems and on education of key stakeholders will be key to foster VBHC implementation in the region. Further research is needed to identify successful implementation cases that may serve as regional benchmark for other Latin American organisations advancing with VBHC.

OBJECTIVE: Low platelet reactivity levels are associated with higher risk of bleeding in patients receiving dual antiplatelet therapy relative to patients with optimal platelet blockade. This study set out to evaluate the prevalence of low platelet reactivity in patients with acute myocardial infarction treated with ticagrelor and aspirin. METHODS: Patients admitted with acute myocardial infarction who were already undergoing dual antiplatelet therapy with aspirin and ticagrelor were enrolled. Blood samples were collected 1 hour before and 2 hours after the maintenance dose of ticagrelor to investigate trough and the peak effects of the drug respectively. Platelet reactivity was measured by three methods: Multiplate®, PFA-100® with Innovance® PFA-P2Y cartridge and PFA-100® with Collagen/ADP cartridge. Platelet reactivity was assessed in the presence of peak levels of ticagrelor and defined according to previously validated cut-offs for each method (<19 AUC, >299 seconds and >116 seconds respectively). The level of significance was set at p<0.05. RESULTS: Fifty patients were enrolled (44% with ST-elevation). Median duration of DAPT was 3 days (interquartile range, 2-5 days). On average, peak and trough platelet reactivity were markedly low and did not differ between different methods. Low platelet reactivity was common, but varied according to analytic method (PFA-100®/Innovance®PFA-P2Y: 86%; Multiplate®: 74%; PFA-100®/Collagen/ADP: 48%; p<0.001). CONCLUSION: Low platelet reactivity was very common in patients with acute myocardial infarction submitted to dual antiplatelet therapy with ticagrelor and aspirin. Findings of this study justify the investigation of less intensive platelet inhibition strategies aimed at reducing the risk of bleeding in this population, such as lower dose regimens or monotherapy with P2Y12 inhibitors.

Objective: To evaluate the prognostic impact of the parameters of myocardial deformation using three-dimensional speckle tracking echocardiography (3DSTE) in patients with breast cancer who underwent chemotherapy with low doses of anthracyclines. Background: Chemotherapy-related cardiotoxicity has an important prognostic impact on cancer survivors. Three-dimensional STE has revealed more consistent data than two-dimensional techniques and may represent a more accurate tool in the evaluation of myocardial function in patients who underwent chemotherapy. Methods: We evaluated patients with breast cancer who were treated with anthracyclines (associated or not with trastuzumab) in five stages: baseline, after cumulative doses of 120 and 240 mg/m2 of doxorubicin, and then, after 6 months and at least 1 year after anthracyclines. Ultrasensitive troponin I (US-TnI) and a standard echocardiography study were performed at each stage. We analyzed left ventricular ejection fraction (LVEF) by Simpson's method, two-dimensional speckle tracking (2DSTE) with longitudinal and radial strain values, and 3DSTE with longitudinal, radial, and circumferential strain as well as twist, torsion, rotation, and three-dimensional global area strain (3DGAS). Cardiotoxicity was defined as a decrease in LVEF by more than 10 percentage points to a value lower than 53%. Results: We evaluated 51 female patients who were aged 50.6 ± 11 years. After the cumulative dose of 240 mg/m2 of doxorubicin, US-TnI was increased (>34 pg/ml) in 21 patients (45%, p > 0.001), LVEF remained unchanged (p = 0.178), while 2DSTE longitudinal strain was decreased (from -17.8% to -17.1%, p < 0.001) and 3DSTE detected changes in longitudinal, radial, circumferential, and area strain. After a lower cumulative dose of doxorubicin (120 mg/m2), 3DGAS (p < 0.001) was the only parameter that was changed. In the follow-up, 7 (13%) patients presented a decrease in LVEF. Three-dimensional GAS early changed to abnormal values was the only variable associated with a subsequent decrease in LVEF (definitive cardiotoxicity). Conclusion: In patients with breast cancer, 3DSTE detected early changes in area strain after very low doses of doxorubicin. The 3DGAS early changed to abnormal values was associated with a subsequent decrease in LVEF, representing a promising technique to predict chemotherapy-induced cardiomyopathy.
ABSTRACT
PURPOSE: To evaluate the cost-effectiveness of percutaneous cryoablation (PCA) versus robot-assisted partial nephrectomy (RPN) in patients with small renal tumors (T1a stage), considering perioperative complications. MATERIALS AND METHODS: Retrospective study from November 2008 to April 2017 of 122 patients with a T1a renal mass who after being analyzed by a multidisciplinary board underwent to PCA (59 patients) or RPN (63 patients). Hospital costs in US dollars, and clinical and tumor data were compared. Non-complicated intervention was considered as an effective outcome. A hypothetical model of possible complications based on Clavien-Dindo classification (CDC) was built, grouping them into mild (CDC I and II) and severe (CDC III and IV). A decision tree model was structured from complications of published data. RESULTS: Patients who underwent PCA were older (62.5 vs. 52.8 years old, p < 0.001), presented with more coronary disease and previous renal cancer (25.4% vs. 10.1%, p = 0.023 and 38% vs. 7.2%, p < 0.001, respectively). Patients treated with PCA had a higher preoperative risk (American Society of Anesthesiologists-ASA ≥ 3) than those in the RPN group (25.4% vs. 0%, p < 0.001). Average operative time was significantly lower with PCA than RPN (99.92 ± 29.05 min vs. 129.28 ± 54.85 min, p < 0.001). Average hospitalization time for PCA was 2.2 ± 2.95 days, significantly lower than RPN (mean 3.03 ± 1.49 days, p = 0.04). The average total cost of PCA was significantly lower than RPN (US$12,435 ± 6,176 vs. US$19,399 ± 6,047, p < 0.001). The incremental effectiveness was 5% higher comparing PCA with RPN, resulting a cost-saving result in favor of PCA. CONCLUSION: PCA was the dominant strategy (less costly and more effective) compared to RPN, considering occurrence of perioperative complications.

BACKGROUND: The impact of simultaneous adverse climate conditions in the risk of myocardial infarction (MI) was not tested before. The aim of the present study was to investigate the impact of the combination of climate and air pollution features in the number of admissions and mortality due to acute myocardial infarction in 39 municipalities of São Paulo from 2012 to 2015. METHODS: Data about MI admissions were obtained from the Brazilian public health system (DataSUS). Daily information on weather were accessed from the Meteorological Database for Teaching and Research. Additionally, daily information on air pollution were obtained from the Environmental Company of the State of São Paulo. A hierarchical cluster analysis was applied for temperature, rainfall patterns, relative air humidity, nitrogen dioxide, particulate matter 2.5 and particulate matter 10. MI admissions and in-hospital mortality were compared among the clusters. RESULTS: Data analysis produced 3 clusters: High temperature variation-Low humidity-high pollution (n=218 days); Intermediate temperature variation/high humidity/intermediate pollution (n=751 days) and low temperature variation/intermediate humidity-low pollution (n=123 days). All environmental variables were significantly different among clusters. The combination of high temperature variation, dry weather and high pollution resulted in a significant 9% increase in hospital admissions for MI [30.5 (IQR 25.0-36.0)]; patients/day; P<0.01). The differences in weather and pollution did not have impact on in-hospital mortality (P=0.88). CONCLUSION: The combination of atmospheric conditions with high temperature variation, lower temperature, dryer weather and increased inhalable particles was associated with a marked increase of hospital admissions due to MI.

OBJECTIVE: To evaluate indications, results and strategy of retinal exams requested at Primary Care Units. METHODS: A retrospective study that analyzed the indications and results of retinal exams, in the modalities clinical dilated fundus exams and color fundus photographs. In the following situations, patients were considered eligible for color fundus photographs if visual acuity was normal and ocular symptoms were absent: diabetes mellitus and/or hypertension, in use of drugs with potential retinal toxicity, diagnosis or suspicion of glaucoma, stable and asymptomatic retinopathies, except myopia greater than -3.00 diopters. RESULTS: A total of 1,729 patients were evaluated (66% female, age 63.5±15.5 years), and 1,190 underwent clinical dilated fundus exam and 539 underwent color fundus photographs. Diabetes was present in 32.2%. The main indications were diabetes (23.7%) and glaucoma evaluation (23.5%). In 3.4% of patients there was no apparent indication. The main results were a large cup/disc ratio (30.7%) and diabetic retinopathy (13.2%). Exam was normal in 9.6%, detected peripheral changes in 7% and could not be performed in 1%. Considering patients eligible for fundus photographs (22.4%), more than half underwent clinical dilated fundus exams. CONCLUSION: Regarding exam modality, there were no important differences in the distribution of indications or diagnosis. Color fundus photograph is compatible with telemedicine and more cost-effective, and could be considered the strategy of choice in some scenarios. Since there are no clear guidelines for retinal exams indications or the modality of choice, this study may contribute to such standardization, in order to optimize public health resources.

INTRODUCTION/OBJECTIVES: In patients who have undergone recent percutaneous coronary intervention (PCI), poor adhesion to antiplatelet agents may increase the risk of stent thrombosis and death. We aimed to investigate the adherence to different P2Y12 receptor inhibitors after PCI with drug-eluting stent in stable and unstable patients and to evaluate the factors associated with low adherence. METHOD: In a prospective study conducted between 2014 and 2018, the 8-item Morisky scale was applied at 30 days and 6 months post-PCI to measure P2Y12 receptor inhibitors adherence. Also, we describe the characteristics of patients using different platelet receptor P2Y12 inhibitors. Regression models were used to identify predictors of poor adherence. RESULTS: A total of 214 patients were included (65 ± 12 years, 81% man, 61% acute coronary syndromes). Patients in the clopidogrel group were older than those in the prasugrel (68 ± 12 vs 59 ± 11 years, P < .01, respectively) or ticagrelor group (68 ± 12 vs 62 ± 12 years, P < .01). Patients with low/moderate adherence at 30 days and 6 months represented, respectively, 19.8% and 27.5% of our sample. Current smokers and preexisting cardiovascular disease at presentation were associated with lower adherence at 30 days. CONCLUSIONS: We found substantial rates of moderate and low adherence to P2Y12 receptor inhibitors early after PCI. Current smokers and preexisting cardiovascular disease at presentation were associated with a lower likelihood of adherence. These results highlight the need of monitoring adherence to medical treatment after PCI.

OBJECTIVE: To evaluate the frequency of severe burnout syndrome among critical care providers and to correlate it with work engagement. METHODS: A self-administered survey including the Maslach Burnout Inventory, Depression Anxiety and Stress Scales, and Gallup questionnaire was distributed. All analyses were stratified by setting (intensive care unit or step-down unit) and by professional group (nurses versus physicians versus physiotherapists). RESULTS: Between February 2017 and June 2017, 206 out of 325 invited professionals (63.4%) answered the questionnaires. Of these, 55 were physicians (26.7%), 88 were physiotherapists (42.7%) and 63 were nurses (30.6%). The frequency of severe burnout was 34.3% (27.9 - 41.4%), and no difference was found between professional groups or settings. The frequency of severe or very severe cases of depression, anxiety or stress was 12.9%, 11.4% and 10.5%, respectively. The median (interquartile range) score observed on the Gallup questionnaire was 41 (34 - 48), and no differences were found between professional groups or settings. There was a negative correlation between burnout and work engagement (r = -0.148; p = 0.035). CONCLUSION: There is a high frequency of severe burnout among critical care providers working in the intensive care unit and step-down unit. There was a negative correlation between burnout and work engagement.
OBJETIVO: Avaliar a frequência de síndrome de burnout grave em profissionais de terapia intensiva e correlacioná-la com o engajamento com o trabalho. MÉTODOS: Foi distribuído um questionário autoaplicável que incluía o Inventário de Burnout de Maslach, a Escala de Depressão Ansiedade e Estresse e o questionário Gallup. Todas as análises foram estratificadas por local de trabalho (unidade de terapia intensiva ou unidade semi-intensiva) e por grupo profissional (enfermeiros versus médicos versus fisioterapeutas). RESULTADOS: Entre fevereiro de 2017 e junho de 2017, 206 dos 325 profissionais convidados (63,4%) responderam aos questionários. Destes, 55 eram médicos (26,7%), 88 eram fisioterapeutas (42,7%) e 63 eram enfermeiros (30,6%). A frequência de burnout grave foi de 34,3% (27,9 - 41,4%), e não se identificaram diferenças entre os grupos profissionais ou locais de trabalho. A frequência de casos graves ou muito graves de depressão, ansiedade ou estresse foi de 12,9%, 11,4% e 10,5%, respectivamente. O escore mediano (intervalo interquartil) observado pelo questionário Gallup foi 41 (34 - 48), e não se observaram diferenças entre os grupos profissionais ou locais de trabalho. Houve correlação negativa entre burnout e engajamento com o trabalho (r = -0,148; p = 0,035). CONCLUSÃO: A frequência de burnout grave foi elevada entre os profissionais de saúde que trabalham na unidade de terapia intensiva e na unidade semi-intensiva. Existe uma correlação negativa entre burnout e engajamento com o trabalho.

The quality of data in electronic healthcare databases is a critical component when used for research and health practice. The aim of the present study was to assess the data quality in the Paulista Cardiovascular Surgery Registry II (REPLICCAR II) using two different audit methods, direct and indirect. The REPLICCAR II database contains data from 9 hospitals in São Paulo State with over 700 variables for 2229 surgical patients. The data collection was performed in REDCap platform using trained data managers to abstract information. We directly audited a random sample (n = 107) of the data collected after 6 months and indirectly audited the entire sample after 1 year of data collection. The indirect audit was performed using the data management tools in REDCap platform. We computed a modified Aggregate Data Quality Score (ADQ) previously reported by Salati et al. (2015). The agreement between data elements was good for categorical data (Cohen κ = 0.7, 95%CI = 0.59-0.83). For continuous data, the intraclass coefficient (ICC) for only 2 out of 15 continuous variables had an ICC < 0.9. In the indirect audit, 77% of the selected variables (n = 23) had a good ADQ score for completeness and accuracy. Data entry in the REPLICCAR II database proved to be satisfactory and showed competence and reliable data for research in cardiovascular surgery in Brazil.

OBJECTIVE: To develop and test a beat-to-beat blood pressure monitoring device during coronary angiography, and compare it with invasive blood pressure monitoring. METHODS: Twenty-eight patients with an indication for hemodynamic study were selected for this investigation, and kept in supine position. Before starting the coronary angiography, they were instructed about the use of the left radial bracelet for beat-to-beat blood pressure monitoring. RESULTS: There was a significant difference between the time required for the catheterization laboratory team to acquire the first invasive blood pressure reading and the time to obtain the first beat-to-beat reading (11.1±5.1 and 1.5±1.8, respectively; p<0.0001). The intraclass correlation coefficients (95%CI) of systolic and diastolic blood pressures were 0.897 (0.780-0.952) and 0.876 (0.734-0.942), indicating good reproducibility. CONCLUSION: This study showed the process to develop a beat-to-beat blood pressure monitoring device. When compared to invasive blood pressure monitoring, there were no significant differences between the two methods. This technique may play a promising coadjuvant role when combined with invasive monitoring during coronary angiography procedures.

INTRODUCTION AND OBJECTIVES: Acute kidney injury (AKI) is frequently observed after transcatheter aortic valve implantation (TAVI) and is associated with higher mortality. However, the impact of AKI on long-term outcomes remains controversial. Therefore, we sought to evaluate the impact of AKI on short- and long-term outcomes following TAVI using the Valve Academic Research Consortium 2 criteria. METHODS: Consecutive patients (n = 794) with severe aortic stenosis who underwent TAVI were included in a multicenter Brazilian registry. Logistic regression analysis was used to identify predictors of AKI. Four-year outcomes were determined as Kaplan-Meier survival curves, and an adjusted landmark analysis was used to test the impact of AKI on mortality among survivors at 12 months. RESULTS: The incidence of AKI after TAVI was 18%. Independent predictors of AKI were age, diabetes mellitus, major or life-threatening bleeding and valve malpositioning. Acute kidney injury was independently associated with higher risk of all-cause death (adjusted HR, 2.8; 95%CI, 2.0-3.9; P < .001) and cardiovascular mortality (adjusted HR, 2.9; 95%CI, 1.9-4.4; P < .001) over the entire follow-up period. However, when considering only survivors at 12 months, there was no difference in both clinical endpoints (adjusted HR, 1.2; 95%CI, 0.5-2.4; P = .71, and HR, 0.7; 95%CI, 0.2-2.1; P = .57, respectively). CONCLUSIONS: Acute kidney injury is a frequent complication after TAVI. Older age, diabetes, major or life-threatening bleeding, and valve malpositioning were independent predictors of AKI. Acute kidney injury is associated with worse short- and long-term outcomes. However, the major impact of AKI on mortality is limited to the first year after TAVI.

PP2B is a Ca2+/calmodulin-dependent protein phosphatase that is ubiquitously expressed in mammals. Among other actions, it is an effector mechanism in NMDA-mediated glutamate neurotransmission as well as a regulator of GSK3beta and MAPK signaling cascades. Because all of these mechanisms have demonstrable roles in the control of circadian rhythyms, we hypothesized that PP2B would be a key regulator of rhythm generation and entrainment, and that through inhibition of its phosphatase activity, the circadian system would be affected by immunosuppressant drug therapy. We report here that immunosuppressant drugs (cyclosporin A, FK506) (1) block the circadian responses to light that underlie photic entrainment; (2) produce circadian phase shifts with a characteristic nonphotic profile; and (3) disrupt circadian rhythm expression when applied chronically. These results indicate a role for PP2B in circadian rhythm generation and entrainment. In addition, because rhythm disturbance has been implicated in impairment of both physical and mental health, we suggest that the use of immunosuppressants would be safer and more efficacious if their impacts on circadian rhythmicity were taken into account.

Value-based health care has been touted as the "strategy that will fix healthcare," yet putting this value agenda to work in the real world is not an easy task. Robert Kaplan and colleagues first introduced the concept of a value management office (VMO) that may help to accelerate the dissemination and adoption of this value agenda. In this article, we describe the first known experience of the implementation of a VMO in a Latin American hospital and the main steps we have already taken to accelerate this value agenda at Hospital Israelita Albert Einstein. We faced a number of challenges in implementing the VMO at Einstein, including integration with existing clinical and financial information areas, transition to a standardized outcomes model, adaptation to our "open medical staff" model by connecting the VMO with the Medical Practice Division, and involvement with our physician-led multidisciplinary groups.

OBJECTIVES: This study sought to examine long-term outcomes with transcatheter aortic valve replacement (TAVR) in women versus men. BACKGROUND: TAVR is commonly performed in women. Previous studies have shown conflicting results with respect to sex differences in outcomes with TAVR. In addition, short-term outcomes have primarily been reported. METHODS: Electronic search was performed until March 2017 for studies reporting outcomes with TAVR in women versus men. Random effects DerSimonian-Laird risk ratios were calculated. Outcomes included all-cause mortality and major cardiovascular events at short- (30 days) and long-term (>1 year) follow-up. RESULTS: Seventeen studies (8 TAVR registries; 47,188 patients; 49.4% women) were analyzed. Women were older but exhibited fewer comorbidities. At 30 days, women had more bleeding (p < 0.001), vascular complications (p < 0.001), and stroke/transient ischemic attack (p = 0.02), without difference in all-cause (p = 0.19) or cardiovascular mortality (p = 0.91) compared with men. However, female sex was associated with lower all-cause mortality at 1 year (risk ratio: 0.85; 95% confidence interval: 0.79 to 0.91; p < 0.001), and longest available follow-up (mean 3.28 ± 1.04 years; risk ratio: 0.86; 95% confidence interval: 0.81 to 0.92; p < 0.001), potentially caused by less moderate/severe aortic insufficiency (p = 0.001), and lower cardiovascular mortality (p = 0.009). The female survival advantage remained consistent across multiple secondary analyses. The risk of stroke, moderate/severe aortic insufficiency, and all-cause mortality seemed to vary based on the type of valve used; however, without significant subgroup interactions. CONCLUSIONS: Despite a higher upfront risk of complications, women derive a better long-term survival after TAVR compared with men.

BACKGROUND: Coronary artery calcification (CAC) and atherosclerotic inflammation associate with increased risk of myocardial infarction (MI). Vascular calcification is regulated by osteogenic proteins (OPs). It is unknown whether an association exists between CAC and plasma OPs and if they are affected by atherothrombotic inflammation. We tested the association of osteogenic and inflammatory proteins with CAC and assessed these biomarkers after MI. METHODS: Circulating OPs (osteoprotegerin, RANKL, fetuin-A, Matrix Gla protein [MGP]) and inflammatory proteins (C-reactive protein, oxidized-LDL, tumoral necrosis factor-α, transforming growth factor [TGF]-ß1) were compared between stable patients with CAC (CAC ≥ 100 AU, n = 100) and controls (CAC = 0 AU, n = 30). The association between biomarkers and CAC was tested by multivariate analysis. In patients with MI (n = 40), biomarkers were compared between acute phase and 1-2 months post-MI, using controls as a baseline. RESULTS: MGP and fetuin-A levels were higher within individuals with CAC. Higher levels of MGP and RANKL were associated with CAC (OR 3.12 [95% CI 1.20-8.11], p = 0.02; and OR 1.75 [95% CI 1.04-2.94] respectively, p = 0.035). After MI, C-reactive protein, OPG and oxidized-LDL levels increased in the acute phase, whereas MGP and TGF-ß1 increased 1-2 months post-MI. CONCLUSIONS: Higher MGP and RANKL levels associate with CAC. These findings highlight the potential role of these proteins as modulators and markers of CAC. In addition, the post-MI increase in OPG and MGP, as well as of inflammatory proteins suggest that the regulation of these OPs is affected by atherothrombotic inflammation.
