05; 95% CI 1.03-1.08), also evident in people with CHD (HR 1.08; 95% CI 1.01-1.14). Point estimates for hazard ratios across all BMI values in participants with T2DM and cancer were consistent with overall positive linear effects but confidence intervals included the null.
These data support the idea that population efforts to promote intentional weight loss towards the normal BMI range would reduce, not enhance, mortality risk in the general population including, importantly, individuals with CHD.

The relationship between preoperative cardiac conduction abnormalities (CCA) and long-term outcomes after transcatheter aortic valve-in-valve implantation (TAVI-VIV) remains unclear. The aim of the study was to evaluate the effects of preoperative CCA on mortality and morbidity after TAVI-VIV and to estimate the impact of new-onset CCA on postoperative outcomes.
Between 2011 and 2020, 201 patients with degenerated aortic bioprostheses were qualified for TAVI-VIV procedures in two German heart centers. Cases with previously implanted permanent rhythm-controlling devices were excluded (n=53). A total of 148 subjects met the eligibility criteria and were divided into 2 study groups according to the presence of preexisting CCA (CCA (n=84) and non-CCA (n=64), respectively). Early and late mortality and morbidity were evaluated. Follow-up functional status was assessed according to New York Heart Association (NYHA) classification.
There were no procedural deaths. TAVI-VIV related new-onset CCAs were observed in 35.8% patients. The 30-day permanent pacemaker implantation rate was 1.6% in non-CCA vs 9.5% in CCA group (p=0.045). Preexisting right bundle-branch block (OR5.01; 95%CI, 1.05-23.84) and first-degree atrioventricular block (OR4.55; 95%CI, 1.10-18.73) were independent predictors of new pacemaker implantation. One-year and five-year probability of survival were comparable in CCA and non-CCA groups 90.3% vs 91.8% and 68.2% vs 74.3%, respectively. Surviving patients with preexisting and new-onset CCA had a worse functional status according to NYHA classification at follow-up.
Preexisting and new-onset postoperative CCAs did not affect early and late mortality after TAVI-VIV procedures, however, they may have a negative impact on late functional status.

Friedreich's ataxia (FA) is a rare autosomal recessive mitochondrial disease most commonly due to a triplet repeat expansion guanine-adenine-adenine (GAA) in the FXN gene. Cardiac disease is the major cause of death, patients with reduced left ventricular ejection fraction (LVEF) having the worse prognosis. Longitudinal strain (LS) appeared to be a better predictor of outcome than LVEF in different diseases. We compared the prognostic value of LS measured from the 4 chambers view to LVEF.
From 2003 to 2017 consecutive patients with FA were included and LS analysis was retrospectively performed.
We studied 140 patients, with a median age of 34 (26-41) years (Q1-Q3) with age at onset of 14 (11-19) years and GAA repeats on the shorter allele of 600 (467-783) pb. Mean LS was 19.9±5.0% and LVEF 64±8%. After a mean follow-up of 7.4±3.9years, 14 patients died. In univariate Cox analysis, all-cause mortality was associated with LS (HR 0.83; 95%CI, 0.75-0.91, p=0.0002), LVEF (HR 0.30; 95%CI, 0.19-0.49, p<0.0001), GAA repeats on the shorter allele (HR 1.29; 95%CI, 1.10-1.51, p=0.002), age at onset (HR 0.87; 95%CI, 0.77-0.98, p=0.018), LVSystolic Diameter (HR 1.17; 95%CI, 1.09-1.26, p<0.0001), LVMass index (HR 1.02; 95%CI, 1.00-1.04, p=0.027), and LVDiastolic Diameter (HR1.12; 95%CI, 1.01-1.23, p=0.028). In multivariate analysis, LVEF was the only independent predictor of mortality (HR 0.41; 95%CI, 0.23-0.74, p=0.0029).
In FA, LS was not an independent predictor of mortality, LVEF remained the only independent predictor in the present study.

The genes share extensive similarity, including the N-terminal (ERG3/FAH) and C-terminal (WAX2) domains. This study, traces the origin, evolutionary history, phylogenetic relationships and variation in copy number of the two genes within and beyond the Viridiplantae (green plants). Protein homologs of both CER1 and CER3 were identified across most Embryophyta (land plants), a single homolog (CER1/3) in charophytes and prasinophytes, and none in the other green, red or brown algae. Ancestral state reconstructions in 100 sequenced Archaeplastida using presence/absence of CER1/3 family genes revealed that the CER1/3 gene probably originated in the common ancestor of Viridiplantae. Phylogenetic analysis of CER1 and CER3 protein sequences from 146 plant species strongly suggests that the two genes originated by duplication of CER1/3 in the ancestral embryophyte. The evolution of CER1 and CER3 genes involved differential divergence of the two domains. Outside Embryophyta, CER1/3 similar sequences identified in diatoms and a cryptophyte, were the closest relatives of the CER1/3 family proteins. Proteins harbouring WAX2-wxAR (WAX2 associated region) similar regions were identified in proteins of bacteria, Archaea, cryptophytes, dinoflagellates and Stramenopiles. The independent existence of both ERG3/FAH and WAX2-wxAR domains in diverse lineages strongly points to the origin of CER1/3 gene in green plants by the fusion of pre-existing domains.Understanding the evolutionary history of symbiotic Cyanobacteria at a fine scale is essential to unveil patterns of associations with their hosts and factors driving their spatiotemporal interactions. Linifanib cost As for bacteria in general, Horizontal Gene Transfers (HGT) are expected to be rampant throughout their evolution, which justified the use of single-locus phylogenies in macroevolutionary studies of these photoautotrophic bacteria. Genomic approaches have greatly increased the amount of molecular data available, but the selection of orthologous, congruent genes that are more likely to reflect bacterial macroevolutionary histories remains problematic. In this study, we developed a synteny-based approach and searched for Collinear Orthologous Regions (COR), under the assumption that genes that are present in the same order and orientation across a wide monophyletic clade are less likely to have undergone HGT. We searched sixteen reference Nostocales genomes and identified 99 genes, part of 28 COR comprising three to eight genes each.
