Children identified as deaf and hard of hearing (DHH) exhibit an increased risk of speech and language difficulties. Nonword repetition (NWR) is a potential tool for identifying language difficulties in children with limited experience with the target language. In this study, we explored associations between auditory, linguistic, demographic and cognitive factors and NWR performance in DHH children and their typically hearing (TH) peers.

Article Synopsis
  • A study aimed to evaluate the outcomes for patients with atrial fibrillation (AF) who experienced intracerebral hemorrhage (ICH) and underwent left atrial appendage occlusion (LAAO) compared to those receiving standard medical treatment.
  • The research involved 151 patients who had LAAO and another 151 matched patients on standard therapy, showing that those with LAAO had a significantly lower risk of death, ischemic stroke, and major bleeding over time.
  • The findings suggest that LAAO could provide significant health benefits for AF patients who suffered an ICH, although further confirmation through randomized clinical trials is needed.

Aims: Randomized trials of coronary bifurcation stenting have shown better outcomes from a simple (provisional) strategy rather than a complex (planned two-stent) strategy in terms of short-term efficacy and safety. Here, we report the 5-year all-cause mortality based on pooled patient-level data from two large bifurcation coronary stenting trials with similar methodology: the Nordic Bifurcation Study (NORDIC I) and the British Bifurcation Coronary Study: old, new, and evolving strategies (BBC ONE).

Methods And Results: Both multicentre randomized trials compared simple (provisional T-stenting) vs.

The hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, and drugs/alcohol (HAS-BLED); anticoagulation and risk factors in atrial fibrillation (ATRIA); modified Outpatient Bleeding Risk Index (mOBRI); and reduction of atherothrombosis for continued health (REACH) schemes are validated bleeding risk-prediction tools, but their predictive performance in patients with AF receiving multiple antithrombotic drugs after percutaneous coronary intervention (PCI) is unknown. We sought to compare the predictive performance of bleeding risk-estimation tools in a cohort of patients with atrial fibrillation (AF) undergoing PCI. Management of patients with AF undergoing coronary artery stenting is a multicenter European prospective registry enrolling patients with AF undergoing PCI.

Current recommendations on the management of patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention with stent (PCI-S) essentially derive from small, single-center, retrospective datasets. To obtain larger and better quality data, we carried out the prospective, multicenter Atrial Fibrillation undergoing Coronary Artery Stenting (AFCAS) study. Therefore, consecutive patients with history of or ongoing AF undergoing PCI-S were enrolled, and occurrence of adverse ischemic and bleeding events recorded during 12 months follow-up.

Background: This prospective multicenter registry used intravascular ultrasound (IVUS) in patients with definite stent thrombosis (ST) to compare rates of incomplete stent apposition (ISA), stent fracture and stent expansion in patients treated with drug-eluting (DES) versus bare metal (BMS) stents. ST is a rare, but potential life threatening event after coronary stent implantation. The etiology seems to be multifactorial.

Molecular events defining enamel matrix removal during amelogenesis are poorly understood. Early reports have suggested that adaptor proteins (AP) participate in ameloblast-mediated endocytosis. Enamel formation involves the secretory and maturation stages, with an increase in resorptive function during the latter.

Uninterrupted oral anticoagulation (OAC) therapy can be the preferred strategy in patients with atrial fibrillation at moderate to high risk of thromboembolism undergoing percutaneous coronary intervention (PCI). To evaluate the need for additional heparins in addition to therapeutic peri-PCI OAC, we assessed bleeding complications and major adverse cardiac and cerebrovascular events in 414 consecutive patients undergoing PCI during therapeutic (international normalized ratio 2 to 3.5) periprocedural OAC.

Background: Leukotrienes are proinflammatory molecules derived from dietary PUFAs and have been associated with cardiovascular disease (CVD). We previously reported that an A→G variant (rs12746200) of the cytosolic phospholipase A2 group IVA gene (PLA2G4A), which encodes the enzyme that liberates PUFAs from cellular membranes for leukotriene synthesis, decreases the risk of CVD.

Objective: We sought to replicate these initial observations with a more clinically relevant phenotype, such as myocardial infarction (MI), and to determine whether dietary PUFAs mediate this association.

The Tsimane of lowland Bolivia are an indigenous forager-farmer population living under conditions resembling pre-industrial European populations, with high infectious morbidity, high infection and inflammation, and shortened life expectancy. Analysis of 917 persons ages 5 to 60+ showed that allele frequencies of 9 SNPs examined in the apolipoprotein E (apoE), C-reactive protein (CRP), and interleukin-6 (IL-6) genes differed from some European, African, and north Asian-derived populations. The apoE2 allele was absent, whereas four SNPs related to CRP and IL-6 were monomorphic: CRP (rs1800947, rs3093061, and rs3093062) and IL-6 (rs1800795).

Background: It is unknown whether the preferred 1-stent bifurcation stenting approach with stenting of the main vessel (MV) and optional side branch stenting using drug-eluting stents should be finalized by a kissing balloon dilatation (FKBD). Therefore, we compared strategies of MV stenting with and without FKBD.

Methods And Results: We randomized 477 patients with a bifurcation lesion to FKBD (n=238) or no FKBD (n=239) after MV stenting.
