Because several articles have reported a prognostic association with the radiological features of ground-glass opacity (GGO), we explored whether the histological presence of a lepidic component had similar significance.

We retrospectively examined 380 consecutive surgically resected lung adenocarcinomas (ADCs) of pStage IA. The tumors were classified into lepidic-positive and lepidic-negative ADCs. Clinicopathologic characteristics, radiographical GGO status, and disease-free survival were compared between lepidic-positive and lepidic-negative adenocarcinomas (ADCs), as well as between part-solid and solid nodules on CT images.

Of the 380 cases, 176 (46.3%) were lepidic-positive ADCs. Of the overall pT1 patients, lepidic-positive ADCs showed significantly better recurrence-free survival (RFS) (5-year 95.4% versus 87.0%, p = 0.005), but this significance was not reproduced in pT1 subcategories (pT1a, pT1b and pT1c). Furthermore, the presence of the lepidic component was not an independent prognostic factor in the multivariate analysis (HR 0.46 [95% CI 0.19-1.14], p= 0.09). We also analyzed the extent of the lepidic component with 10% incremental valuables. Although we found that a 10% or greater extent of lepidic component made the RFS difference the largest, a clear prognostic impact was not obtained with this cutoff point.

Although lepidic-positive ADCs tended to have a favorable outcome, the lepidic component was not a clear independent prognostic factor in pStage I ADC.

The large number of polyploid taxa poses significant challenges for phylogenetic and evolutionary studies on this subfamily. In this study, we cloned and sequenced three single-copy nuclear loci to investigate the evolution of polyploidy in the Cyprininae. Topologies of nuclear gene trees were compared with a newly reconstructed mitochondrial tree. The data provided herein corroborate the hybrid origins of the tribes Torini, Cyprinini, Spinibarbini, Barbini, and also Probarbini. Based on results from this study and previous studies, we hypothesize that at least 13 independent polyploidization events have occurred during the evolution of the Cyprininae. We offer hypotheses on the origin of each polyploid group and show that a diploid group or the diploid ancestor of a polyploid group might have served as progenitor of one or two other polyploid groups. The evolutionary history of Cyprinine (since its first divergence) can be divided into three stages the "Diploid stage" (69.2-43.4 Ma or million years ago), the "Tetraploidization stage" (43.4-18.9 Ma), and the "Hexaploidization stage" (18.9 Ma to present). The second stage is when all tetraploidization events happened, while the last stage is when all hexaploidization events and most genus- or species-specific polyploidization events occurred. The post-polyploidization dynamics of polyploid groups are complicated and warrant more genomic level studies. We showed that the subfamily Cyprininae may represent a more complicated polyploid system than most, if not all, other vertebrates and some plants, if one or more of the following factors are considered number of polyploid species, number of different ploidy levels, and number and type of independent polyploidization events.

Cardiac intensive care units (CICUs) serve medically complex patients with multi-organ dysfunction. Whether a CICU staffed full time by heart failure (HF) specialists is associated with decreased mortality is unclear.

Retrospective review of consecutive CICU admissions from January 1, 2012 to Dec 31, 2016 was performed. In January 2014, the CICU changed from an open unit staffed by any cardiologist to a closed unit managed by HF specialists. Patients' baseline characteristics were determined, and a multivariate regression analysis was performed to ascertain CICU mortality. Baseline severity of illness was higher in the closed/HF specialist CICU model (p<0.001). Death occurred in 101 of 1,185 CICU admissions (8.5%) in the open unit model and in 139 of 2,163 admissions (6.4%) in the closed/HF specialist model (absolute risk reduction 2.1%, 95% confidence interval [CI] 0.1-4.0%, p =0.01). The transition from an open to a closed/HF specialist model was associated with a lower overall CICU mortality (odds ratio [OR] 0.63; 95% CI 0.43-0.93). Prespecified interaction of a mechanical circulatory support (MCS) device and unit model showed that treatment with MCS was associated with lower CICU mortality in the closed/HF specialist model (OR 0.6; 95% CI 0.18-0.78, p for interaction <0.01).

Transition to a closed unit model staffed with a dedicated HF specialist is associated with lower CICU mortality.

Registries show international variations in the characteristics and outcome of patients with heart failure (HF) but national samples are rarely large, and case-selection may be biased due to enrolment in academic centres. National administrative datasets provide large samples with a low risk of bias. In this study, we compared the characteristics, healthcare resource utilization (HRU) and outcomes of patients with primary HF hospitalizations (HFH) using electronic health records (EHR) from four high-income countries (USA, UK, Taiwan, Japan) on three continents.

We used EHR to identify unplanned HFH between 2012-2014. We identified 231,512, 10,991, 36,900 and 133,982 patients with a primary HFH from USA, UK, Taiwan and Japan, respectively. HFH per 100,000 population was highest in USA and lowest in Taiwan. Patients in Taiwan and Japan were older but fewer were obese or had chronic kidney disease. LOHS was shortest in USA (median 4 days) and longer in UK, Taiwan and Japan (medians 7, 9 and 17 days, respectively). HRU during hospitalization was highest in Japan and lowest in UK. Crude and direct standardized in-hospital mortality was lowest in USA (direct standardized rates 1.8 [95%CI1.7-1.9]%)and progressively higher in Taiwan (direct standardized rates 3.9 [95%CI3.8-4.1]%), UK (direct standardized rates 6.4 [95%CI6.1-6.7]%) and Japan (direct standardized rates 6.7 [95%CI6.6-6.8]%). 30-day all-cause (25.8%) and HF (7.2%) readmissions were highest in USA and lowest in Japan (11.9% and 5.1% respectively).

Marked international variations in patient characteristics, HRU and clinical outcome exist; understanding them might inform health care policy and international trial design.

The V122I variant in transthyretin (TTR) is the most common amyloidogenic mutation worldwide. The aim of this study is to describe the cardiac phenotype and risk for adverse cardiovascular outcomes of young V122I TTR carriers in the general population.

TTR genotypes were extracted from whole-exome sequence data in participants of the Dallas Heart Study. Participants with African ancestry, available V122I TTR genotypes (N=1,818), and either cardiac magnetic resonance imaging (CMR) (n=1,364), or long-term follow-up (n=1,532) were included. The prevalence of V122I TTR carriers (45±10 years) was 3.2% (n/N=59/1,818). V122I TTR carriers had higher baseline LV wall thickness (LVWT, 8.52±1.82 vs. 8.21±1.62 mm; adjusted P=0.038) than non-carriers, but no differences in other CMR measures (P>0.05 for all). Although carrier status was not associated with amino terminal pro-B-type natriuretic peptide (NT-proBNP) at baseline (P=0.79), V122I TTR carriers had a greater increase in NT-proBNP on follow-up than non-carriers (median [interquartile range] 28.5 [11.4-104.1] vs. 15.9 [0.0-43.0] pg/mL; adjusted P=0.018). V122I TTR carriers were at a higher adjusted risk of heart failure (HF) (HR 3.82, 95% CI 1.80-8.13, P<0.001), cardiovascular death (HR 2.65, 95% CI 1.14-6.15, P=0.023), and all-cause mortality (HR 1.95, 95% CI 1.08-3.51, P=0.026) in comparison with non-carriers.

V122I TTR carrier status was associated with a greater increase in NT-proBNP, slightly greater LVWT, and a higher risk for HF, cardiovascular death, and all-cause mortality. These findings suggest the need to develop amyloidosis screening strategies for V122I TTR carriers.

Among patients with acute dyspnea, concentrations of N-terminal pro-B-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin T (hs-cTnT) and insulin-like growth factor binding protein-7 (IGFBP7) predict cardiovascular outcomes and death. Understanding the optimal means to interpret these elevated biomarkers in patients presenting with acute dyspnea remains unknown.

Concentrations of NT-proBNP, hs-cTnT, and IGFBP7 were analyzed in 1,448 patients presenting with acute dyspnea from the prospective, multicenter ICON-RELOADED (International Collaborative of NT-proBNP-Re-evaluation of Acute Diagnostic Cut-Offs in the Emergency Department) Study. Eight biogroups were derived based upon patterns in biomarker elevation at presentation and compared for differences in baseline characteristics. Of 441 patients with elevations in all three biomarkers, 218 (49.4%) were diagnosed with acute heart failure (HF). The frequency of acute HF diagnosis in this biogroup was higher than those with elevations in in the number of elevated biomarkers at presentation may allow for more efficient clinical risk stratification of short-term mortality and HF rehospitalization.Depressed people are prone to sleep disturbance, which may in return perpetuate the depression. Both depression and sleep disturbance influence proinflammatory cytokines interleukin (IL) 6 and 1β. Thus interventions for depression should consider the effect on sleep disturbance, and vice versa. Integrative Body-Mind-Spirit (IBMS) and Qigong interventions have been applied in a wide range of health and mental health conditions, including depression and sleep disturbance. This study aimed to evaluate the effect of these two mind-body therapies for persons with both depressive symptoms and sleep disturbance. A three-arm randomized controlled trial was conducted among 281 participants, who were randomly assigned to either IBMS, Qigong or wait list control group. Participants in IBMS and Qigong groups received eight weekly sessions of intervention. Outcome measures were plasma concentrations of IL-6 and IL-1β, and a questionnaire containing Pittsburgh Sleep Quality Index, Center for Epidemiologic Studies Depressioons in relieving depression and sleep disturbance, and in reducing IL-6 and IL-1β levels.
