Abstract Background Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS) is being increasingly performed. Objectives From the Bicuspid AS TAVR ...multicenter registry, the procedural and clinical outcomes in patients with bicuspid versus tricuspid AS were compared. Methods Outcomes of 561 patients with bicuspid AS and 4,546 patients with tricuspid AS were compared after propensity-score matching assembling 546 pairs of patients with similar baseline characteristics. Procedural and clinical outcomes were recorded according to VARC-2 criteria. Results Compared to patients with tricuspid AS, patients with bicuspid AS had more frequent conversion to surgery (2.0% vs. 0.2%; p=0.006) and significantly lower device success rate (85.3% vs. 91.4%; p=0.002). Early generation devices (Sapien XT/CoreValve) were implanted in 320 patients with bicuspid and 321 patients with tricuspid AS whereas new generation devices (Sapien 3/Lotus/Evolut R) were implanted in 226 and 225 patients with bicuspid and tricuspid AS, respectively. Within the group receiving early generation devices, bicuspid AS had more frequent aortic root injury (4.5% vs. 0.0%; p=0.015) when receiving the Sapien XT, and moderate-to-severe paravalvular leak (19.4% vs. 10.5%; p=0.02) when receiving the CoreValve. Among patients with new generation devices, however, procedural results were comparable across different prostheses. The cumulative all-cause mortality rates at 2-year were comparable between bicuspid and tricuspid AS (17.2% vs. 19.4%; p=0.28). Conclusions Compared to tricuspid AS, TAVR in bicuspid AS was associated with similar prognosis although lower device success rate. Procedural differences were observed in patients treated with the early generation devices whereas no differences were observed with the new generation devices.
Atopic dermatitis is a chronic, pruritic inflammatory dermatosis that affects up to 25% of children and 2% to 3% of adults. This guideline addresses important clinical questions that arise in atopic ...dermatitis management and care, providing recommendations based on the available evidence. In this third of 4 sections, treatment of atopic dermatitis with phototherapy and systemic immunomodulators, antimicrobials, and antihistamines is reviewed, including indications for use and the risk-benefit profile of each treatment option.
Regurgitative gastroesophageal reflux disease (GERD) refractive to medical treatment is common and caused by mechanical failure of the anti-reflux barrier. We compared the effects of magnetic ...sphincter augmentation (MSA) with those of proton-pump inhibitors (PPIs) in a randomized trial.
Patients with moderate to severe regurgitation (assessed by the foregut symptom questionnaire) despite once-daily PPI therapy (n = 152) were randomly assigned to groups given twice-daily PPIs (n = 102) or laparoscopic MSA (n = 50) at 20 sites, from July 2015 through February 2017. Patients answered questions from the foregut-specific reflux disease questionnaire and GERD health-related quality of life survey about regurgitation, heartburn, dysphagia, bloating, diarrhea, flatulence, and medication use, at baseline and 6 and 12 months after treatment. Six months after PPI therapy, MSA was offered to patients with persistent moderate to severe regurgitation and excess reflux episodes during impedance or pH testing on medication. Regurgitation, foregut scores, esophageal acid exposure, and adverse events were evaluated at 1 year.
Patients in the MSA group and those who crossed over to the MSA group after PPI therapy (n = 75) had similar outcomes. MSA resulted in control of regurgitation in 72/75 patients (96%); regurgitation control was independent of preoperative response to PPIs. Only 8/43 patients receiving PPIs (19%) reported control of regurgitation. Among the 75 patients who received MSA, 61 (81%) had improvements in GERD health-related quality of life improvement scores (greater than 50%) and 68 patients (91%) discontinued daily PPI use. Proportions of patients with dysphagia decreased from 15% to 7% (P < .005), bloating decreased from 55% to 25%, and esophageal acid exposure time decreased from 10.7% to 1.3% (P < .001) from study entry to 1-year after MSA (Combined P < .001). Seventy percent (48/69) of patients had pH normalization at study completion. MSA was not associated with any peri-operative events, device explants, erosions, or migrations.
In a prospective study, we found MSA to reduce regurgitation in 95% of patients with moderate to severe regurgitation despite once-daily PPI therapy. MSA is superior to twice-daily PPIs therapy in reducing regurgitation. Relief of regurgitation is sustained over 12 months. ClinicalTrials.gov no: NCT02505945
Summary Background Neratinib, an irreversible tyrosine-kinase inhibitor of HER1, HER2, and HER4, has clinical activity in patients with HER2-positive metastatic breast cancer. We aimed to investigate ...the efficacy and safety of 12 months of neratinib after trastuzumab-based adjuvant therapy in patients with early-stage HER2-positive breast cancer. Methods We did this multicentre, randomised, double-blind, placebo-controlled, phase 3 trial at 495 centres in Europe, Asia, Australia, New Zealand, and North and South America. Eligible women (aged ≥18 years, or ≥20 years in Japan) had stage 1–3 HER2-positive breast cancer and had completed neoadjuvant and adjuvant trastuzumab therapy up to 2 years before randomisation. Inclusion criteria were amended on Feb 25, 2010, to include patients with stage 2–3 HER2-positive breast cancer who had completed trastuzumab therapy up to 1 year previously. Patients were randomly assigned (1:1) to receive oral neratinib 240 mg per day or matching placebo. The randomisation sequence was generated with permuted blocks stratified by hormone receptor status (hormone receptor-positive oestrogen or progesterone receptor-positive or both vs hormone receptor-negative oestrogen and progesterone receptor-negative), nodal status (0, 1–3, or ≥4), and trastuzumab adjuvant regimen (sequentially vs concurrently with chemotherapy), then implemented centrally via an interactive voice and web-response system. Patients, investigators, and trial sponsors were masked to treatment allocation. The primary outcome was invasive disease-free survival, as defined in the original protocol, at 2 years after randomisation. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov , number NCT00878709. Findings Between July 9, 2009, and Oct 24, 2011, we randomly assigned 2840 women to receive neratinib (n=1420) or placebo (n=1420). Median follow-up time was 24 months (IQR 20–25) in the neratinib group and 24 months (22–25) in the placebo group. At 2 year follow-up, 70 invasive disease-free survival events had occurred in patients in the neratinib group versus 109 events in those in the placebo group (stratified hazard ratio 0·67, 95% CI 0·50–0·91; p=0·0091). The 2-year invasive disease-free survival rate was 93·9% (95% CI 92·4–95·2) in the neratinib group and 91·6% (90·0–93·0) in the placebo group. The most common grade 3–4 adverse events in patients in the neratinib group were diarrhoea (grade 3, n=561 40% and grade 4, n=1 <1% vs grade 3, n=23 2% in the placebo group), vomiting (grade 3, n=47 3% vs n=5 <1%), and nausea (grade 3, n=26 2% vs n=2 <1%). QT prolongation occurred in 49 (3%) patients given neratinib and 93 (7%) patients given placebo, and decreases in left ventricular ejection fraction (≥grade 2) in 19 (1%) and 15 (1%) patients, respectively. We recorded serious adverse events in 103 (7%) patients in the neratinib group and 85 (6%) patients in the placebo group. Seven (<1%) deaths (four patients in the neratinib group and three patients in the placebo group) unrelated to disease progression occurred after study drug discontinuation. The causes of death in the neratinib group were unknown (n=2), a second primary brain tumour (n=1), and acute myeloid leukaemia (n=1), and in the placebo group were a brain haemorrhage (n=1), myocardial infarction (n=1), and gastric cancer (n=1). None of the deaths were attributed to study treatment in either group. Interpretation Neratinib for 12 months significantly improved 2-year invasive disease-free survival when given after chemotherapy and trastuzumab-based adjuvant therapy to women with HER2-positive breast cancer. Longer follow-up is needed to ensure that the improvement in breast cancer outcome is maintained. Funding Wyeth, Pfizer, Puma Biotechnology.
Abstract Objectives The purpose of this study was to determine the safety and effectiveness of the SAPIEN XT versus SAPIEN systems (Edwards Lifesciences, Irvine, California) in patients with ...symptomatic, severe aortic stenosis (AS) who were not candidates for surgery. Background Transcatheter aortic valve replacement (TAVR) has become the standard of care for inoperable patients with severe, symptomatic AS. In the PARTNER (Placement of Aortic Transcatheter Valves) IB trial, a reduction in all-cause mortality was observed in patients undergoing TAVR with the balloon-expandable SAPIEN transcatheter heart valve compared with standard therapy, but the SAPIEN valve was associated with adverse periprocedural complications, including vascular complications, major bleeding, and paravalvular regurgitation. The newer, low-profile SAPIEN XT system was developed to reduce these adverse events. Methods A total of 560 patients were enrolled at 28 sites in the United States from April 2011 to February 2012. Patients were randomized to receive the SAPIEN or SAPIEN XT systems. The primary endpoint was a nonhierarchical composite of all-cause mortality, major stroke, and rehospitalization at 1 year in the intention-to-treat population, assessed by noninferiority testing. Pre-specified secondary endpoints included cardiovascular death, New York Heart Association functional class, myocardial infarction, stroke, acute kidney injury, vascular complications, bleeding, 6-min walk distance, and valve performance (by echocardiography). Results Both overall and major vascular complications were higher at 30 days in patients undergoing TAVR with SAPIEN compared with SAPIEN XT (overall: 22.1% vs. 15.5%; p = 0.04; major: 15.2% vs. 9.5%; p = 0.04). Bleeding requiring blood transfusions was also more frequent with SAPIEN compared with SAPIEN XT (10.6% vs. 5.3%; p = 0.02). At 1-year follow-up, the nonhierarchical composite of all-cause mortality, major stroke, or rehospitalization was similar (37.7% SAPIEN vs. 37.2% SAPIEN XT; noninferiority p value <0.002); no differences in the other major pre-specified endpoints were found. Conclusions In inoperable patients with severe, symptomatic AS, the lower-profile SAPIEN XT is noninferior to SAPIEN with fewer vascular complications and a lesser need for blood transfusion.

Abstract Background Adherence to evidence-based cardiovascular (CV) medications after an acute myocardial infarction (MI) is low after the first 6 months. The use of fixed-dose combinations (FDC) has ...been shown to improve treatment adherence and risk factor control. However, no previous randomized trial has analyzed the impact of a polypill strategy on adherence in post-MI patients. Objectives The cross-sectional FOCUS (Fixed-Dose Combination Drug for Secondary Cardiovascular Prevention) study (Phase 1) aimed to elucidate factors that interfere with appropriate adherence to CV medications for secondary prevention after an acute MI. Additionally, 695 patients from Phase 1 were randomized into a controlled trial (Phase 2) to test the effect of a polypill (containing aspirin 100 mg, simvastatin 40 mg, and ramipril 2.5, 5, or 10 mg) compared with the 3 drugs given separately on adherence, blood pressure, and low-density lipoprotein cholesterol, as well as safety and tolerability over a period of 9 months of follow-up. Methods In Phase 1, a 5-country cohort of 2,118 patients was analyzed. Patients were randomized to either the polypill or 3 drugs separately for Phase 2. Primary endpoint was adherence to the treatment measured at the final visit by the self-reported Morisky-Green questionnaire (MAQ) and pill count (patients had to meet both criteria for adherence at the in-person visit to be considered adherent). Results In Phase 1, overall CV medication adherence, defined as an MAQ score of 20, was 45.5%. In a multivariable regression model, the risk of being nonadherent (MAQ <20) was associated with younger age, depression, being on a complex medication regimen, poorer health insurance coverage, and a lower level of social support, with consistent findings across countries. In Phase 2, the polypill group showed improved adherence compared with the group receiving separate medications after 9 months of follow-up: 50.8% versus 41% (p = 0.019; intention-to-treat population) and 65.7% versus 55.7% (p = 0.012; per protocol population) when using the primary endpoint, attending the final visit with MAQ = 20 and high pill count (80% to 110%) combined, to assess adherence. Adherence also was higher in the FDC group when measured by MAQ alone (68% vs. 59%, p = 0.049). No treatment difference was found at follow-up in mean systolic blood pressure (129.6 mm Hg vs. 128.6 mm Hg), mean low-density lipoprotein cholesterol levels (89.9 mg/dl vs. 91.7 mg/dl), serious adverse events (23 vs. 21), or death (1, 0.3% in each group). Conclusions For secondary prevention following acute MI, younger age, depression, and a complex drug treatment plan are associated with lower medication adherence. Meanwhile, adherence is increased in patients with higher insurance coverage levels and social support. Compared with the 3 drugs given separately, the use of a polypill strategy met the primary endpoint for adherence for secondary prevention following an acute MI.

Summary Background Findings from the randomised phase 3 NeoALTTO trial in women with HER2-positive early breast cancer showed that the combination of lapatinib and trastuzumab significantly improved ...rates of pathological complete response compared with either drug alone. Here, we report data for the prespecified secondary endpoints of event-free and overall survival, and assess the association between these outcomes and pathological complete response. Methods We enrolled women with HER2-positive early breast cancer and randomly assigned them to receive oral lapatinib (1500 mg), intravenous trastuzumab (4 mg/kg loading dose followed by 2 mg/kg), or lapatinib (1000 mg) plus trastuzumab (same dose as for single agent) in combination for 6 weeks, followed by an additional 12 weeks of the assigned anti-HER2 therapy in combination with weekly paclitaxel (80 mg/m2 ). Definitive surgery was done 4 weeks after the last dose of paclitaxel. After surgery, women received three cycles of FEC (fluorouracil 500 mg/m2 plus epirubicin 100 mg/m2 plus cyclophosphamide 500 mg/m2 ) given intravenously every 3 weeks, followed by 34 weeks of the same assigned neoadjuvant anti-HER2 therapy. The primary endpoint was pathological complete response. Secondary endpoints included event-free and overall survival (intention-to-treat analysis), and the association between pathological complete response and event-free or overall survival (analysed by landmark analysis at 30 weeks after randomisation). Follow-up is ongoing, and the trial is registered with ClinicalTrials.gov , number NCT00553358. Findings 455 patients were enrolled: 154 (34%) were assigned to the lapatinib group, 149 (33%) to the trastuzumab group, and 152 (33%) to the lapatinib plus trastuzumab group. At an event follow-up of 3·77 years (IQR 3·50–4·22), 3-year event-free survival was 78% (95% CI 70–84) in the lapatinib group, 76% (68–82) in the trastuzumab group, and 84% (77–89) in the combination group. Event-free survival did not differ between the lapatinib and trastuzumab groups (HR 1·06, 95% CI 0·66–1·69, p=0·81), nor between the combination and trastuzumab groups (0·78, 0·47–1·28, p=0·33). Median survival follow-up was 3·84 years (IQR 3·60–4·24), and 3-year overall survival was 93% (95% CI 87–96) for lapatinib, 90% (84–94) for trastuzumab, and 95% (90–98) for combination therapy. Overall survival did not significantly differ between the lapatinib and trastuzumab groups (HR 0·86, 95% CI 0·45–1·63, p=0·65), nor between the combination and trastuzumab groups (0·62, 0·30–1·25, p=0·19). Landmark analyses showed that 3-year event-free survival was significantly improved for women who achieved pathological complete response compared with those who did not (HR 0·38, 95% CI 0·22–0·63, p=0·0003), as was 3-year overall survival (0·35, 0·15–0·70, p=0·005). Adverse events occurred in 149 (99%) patients receiving lapatinib, 142 (96%) patients receiving trastuzumab, and 147 (99%) patients receiving combination therapy. The most common adverse events were diarrhoea, rash or erythema, hepatic adverse events, and neutropenia (not related to FEC administration), and were consistent with known safety profiles of lapatinib and trastuzumab. Three primary and eight secondary cardiac events occurred, with no significant difference in incidence between treatment groups for primary or any cardiac events. Interpretation Although event-free survival or overall survival did not differ between treatment groups, findings from our study confirm that patients who achieve pathological complete response after neoadjuvant anti-HER2 therapy have longer event-free and overall survival than do patients without pathological complete response.
