Prognostic value of geriatric and cardiac parameters for one-year mortality in older heart failure patients. A multicentre, observational, prospective study.

Purpose: Heart failure is prevalent among older people and has a poor prognosis. The aim of this study is to identify potential prognostic, geriatric, and cardiac parameters which could help clinicians identify older heart failure patients at high risk for one-year mortality.

Methods: The multicentre, observational cohort study which included 147 heart failure patients aged ≥75 years, hospitalized in the cardiac or geriatric department in two hospitals.

Study of Microstructural Morphology of Ti-6Al-4V Alloy by Crystallographic Analysis and Phase Field Simulation.

Formation of a habit plane during martensitic transformation is related to an invariant plane strain transformation, which involves dislocation glide and twins. In the current work, the Phenomenological Theory of Martensitic Transformation (PTMT) is employed to study the crystallographic features while the phase field simulation is used to study the microstructure evolution for martensitic transformation of Ti-6Al-4V alloy. Results show that mechanical constraints play a key role in the microstructure evolution.

Analysis of ESAFORM 2021 cup drawing benchmark of an Al alloy, critical factors for accuracy and efficiency of FE simulations.

This article details the ESAFORM Benchmark 2021. The deep drawing cup of a 1 mm thick, AA 6016-T4 sheet with a strong cube texture was simulated by 11 teams relying on phenomenological or crystal plasticity approaches, using commercial or self-developed Finite Element (FE) codes, with solid, continuum or classical shell elements and different contact models. The material characterization (tensile tests, biaxial tensile tests, monotonic and reverse shear tests, EBSD measurements) and the cup forming steps were performed with care (redundancy of measurements).

A case of disseminated tuberculosis during a twin pregnancy following in vitro fertilization.

A woman presented with cough, fever, and dyspnea during a twin pregnancy following a 13th in vitro fertilization procedure. Ultimately, she was diagnosed with miliary tuberculosis and tuberculostatic treatment was initiated, complicated by drug-induced hepatotoxicity. In retrospect, previous pelvic tuberculosis had likely been overlooked.

Helios expressing regulatory T cells are correlated with decreased IL-2 producing CD8 T cells and antibody diversity in Mozambican individuals living chronically with HIV-1.

Background: Human immunodeficiency virus type 1 (HIV-1) causes impairment of T and B cell responses, which begins during the acute phase of infection and is not completely restored by antiretroviral treatment. Regulatory T cell (Tregs) can improve overall disease outcome by controlling chronic inflammation but may also suppress beneficial HIV-1 specific immune responses. We aimed to analyze the profile of Tregs and their correlation with the status of T cells activation, the expression of IL-2 and IFNγ and the profile of HIV-1 specific antibodies response in Mozambican people living chronically with HIV-1 (PLWH-C).
