Signal transducer and activator of transcription 3 (STAT3) is a central regulator of immune homeostasis. STAT3 levels are strictly controlled, and STAT3 impairment contributes to several diseases including the monogenic autosomal-dominant hyper-immunoglobulin E (IgE) syndrome (AD-HIES). We investigated patients of four consanguineous families with an autosomal-recessive disorder resembling the phenotype of AD-HIES, with symptoms of immunodeficiency, recurrent infections, skeletal abnormalities, and elevated IgE.

Primary immunodeficiencies (PIDs) represent a group of mostly monogenic disorders caused by loss- or gain-of-function mutations in over 340 known genes that lead to abnormalities in the development and/or the function of the immune system. However, mutations in different genes can affect the same cell-signaling pathway and result in overlapping clinical phenotypes. In particular, mutations in the genes encoding for members of the phosphoinositide3-kinase (PI3K)/AKT/mTOR/S6 kinase (S6K) signaling cascade or for molecules interacting with this pathway have been associated with different PIDs that are often characterized by the coexistence of both immune deficiency and autoimmunity.

Background: In 2002, the European Society of Cardiology conducted the Euro Heart Survey (EHS), while in 2014concluded 1-year follow-up of the EURObservational Research Programme AF (EORP-AF) Pilot Registry.

Methods: We analysed differences in clinical profiles, therapeutic approaches and outcomes between these two cohorts after propensity score matching (PSM).

Results: After PSM, 5206 patients were analysed.

Aims: Although oral anticoagulants (OACs) are effective in preventing stroke in older people with atrial fibrillation (AF), they are often underused in this particularly high-risk population. The aim of the present study was to assess the appropriateness of OAC prescription and its associated factors in hospitalized patients aged 65 years or older.

Methods: Data were obtained from the retrospective phase of Simulation-based Technologies to Improve the Appropriate Use of Oral Anticoagulants in Hospitalized Elderly Patients With Atrial Fibrillation (SIM-AF) study, held in 32 Italian internal medicine and geriatric wards.

Background: Lowering mortality and hospitalization of older adults is one of the main goals of public health to improve both health systems' sustainability and older adults' quality of life. The aim of this study is to identify the determinants associated with mortality and the use of hospital services in the population older than 64 years of age.

Methods: A randomized sample from the population of the Lazio region (Italy) above the age of 64 was enrolled in 2014 by the administration of a questionnaire to assess frailty; the rates of use of hospital services and mortality in the year following the enrolment have been retrieved by the regional database.

Chronic obstructive pulmonary disease (COPD) increases the risk of mortality in non-valvular atrial fibrillation (NVAF) patients. Data on the relationship of COPD to major cardiovascular events (MACE) in AF have not been defined. The aim of the study is to assess the predictive value of COPD on incident MACE in NVAF patients over a 3-year follow-up.

Background: Use of oral anticoagulant (OAC) therapy in atrial fibrillation (AF) is associated with an inherited risk of bleeding. Benefits and risks of OAC restarting after a major bleeding are still uncertain. We aimed to assess effectiveness and safety of restarting OAC in AF patients after a major bleeding event.

Background: Among rate-control or rhythm-control strategies, there is conflicting evidence as to which is the best management approach for non-valvular atrial fibrillation (AF) in elderly patients.

Design: We performed an ancillary analysis from the 'Registro Politerapie SIMI' study, enrolling elderly inpatients from internal medicine and geriatric wards.

Methods: We considered patients enrolled from 2008 to 2014 with an AF diagnosis at admission, treated with a rate-control-only or rhythm-control-only strategy.

Background: The impact of overweight and obesity on outcomes in "real world" patients with atrial fibrillation (AF) is not fully defined. Second, sex differences in AF outcomes may also exist.

Methods And Results: The aim was to investigate outcomes at 1 year follow-up for AF patients enrolled in the EORP-AF Registry, according to BMI (kg/m ), comparing patients with normal BMI (18.

Background: Concomitant aspirin (ASA) is often prescribed in anticoagulated patients with atrial fibrillation (AF). We aimed to investigate the relationship between ASA use and quality of anticoagulation control determining major adverse outcomes.

Methods: An ancillary analysis of patients in the warfarin arm of the SPORTIF III and V trials was performed.

Background: Non-vitamin K antagonist oral anticoagulants (NOACs) have been proposed as an alternative to vitamin K antagonists (VKA) for atrial fibrillation (AF) patients. Some studies have proposed that well-managed warfarin therapy is still a valid alternative as efficacious as NOACs but the potential impact and absolute effect of NOACs in "real world" optimally management of VKA AF patients is unknown.

Purpose: To estimate the potential absolute benefit in clinical outcome rates if the optimally anticoagulated "real-world" AF patients with acenocoumarol had been treated with NOACs.

Background: More evidence is needed on the optimal antithrombotic regimen in elderly patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI).

Hypothesis: Octogenarian patients (aged ≥80 years) with AF who underwent PCI have worse 12-month clinical outcome, compared with younger patients.

Methods: We performed a post-hoc analysis of data from the prospective, multicenter AFCAS registry, which enrolled consecutive patients with AF who underwent PCI and stenting.

Article Synopsis
  • The TRPM7 protein plays a dual role as a cation channel and kinase, impacting thymopoiesis and cytokine expression in immune cells.
  • Research using kinase-dead mutant mice reveals that TRPM7's enzymatic activity is crucial for the gut-homing of specific T cells (intra-epithelial lymphocytes) and their ability to express the molecule CD103.
  • The study suggests that regulating TRPM7 kinase activity can influence T cell differentiation and potentially offers new therapeutic strategies for conditions like acute graft-versus-host disease.

Atrial fibrillation (AF), which is the most diagnosed arrhythmia, is becoming a significant issue for health policy-makers. In particular, more and more attention is being devoted to AF prevention. Indeed, several studies recently published point out how targeted interventions could be useful in reducing the risk of AF occurrence (or recurrence).

Here we report concentrations of pollutants in floating plastics from the North Pacific accumulation zone (NPAC). We compared chemical concentrations in plastics of different types and sizes, assessed ocean plastic potential risks using sediment quality criteria, and discussed the implications of our findings for bioaccumulation. Our results suggest that at least a fraction of the NPAC plastics is not in equilibrium with the surrounding seawater.

Background And Purpose: The use of oral anticoagulant therapy for stroke prevention in atrial fibrillation has been transformed by the availability of the nonvitamin K antagonist oral anticoagulants. Real-world studies on the use of nonvitamin K antagonist oral anticoagulants would help elucidate their effectiveness and safety in daily clinical practice. Apixaban was the third nonvitamin K antagonist oral anticoagulants introduced to clinical practice, and increasing real-world studies have been published.

Background: Oral anticoagulation is the mainstay of stroke prevention in atrial fibrillation (AF), but must be balanced against the associated bleeding risk. Several risk scores have been proposed for prediction of bleeding events in patients with AF.

Objectives: To compare the performance of contemporary clinical bleeding risk scores in 18 113 patients with AF randomized to dabigatran 110 mg, 150 mg or warfarin in the RE-LY trial.
