Abstract

For years, coated metal sheets have been used in cookware manufacturing. This paper focuses on employing experimental and numerical analyses to determine the quality and formability of commercially available polytetrafluoroethylene (PTFE)‐coated aluminium sheets. For this purpose, examinations of the coating's microstructure, hardness, and friction coefficient through nano‐indentation and scratch tests, were investigated. Tensile test was performed to obtain some mechanical characteristics of the coated aluminium sheets. Moreover, the forming limit curve for the studied material was established by conducting Nakazima test, covering both negative and positive domains of minor strain. The influence of sheet thickness on formability was investigated since using 2 mm and 1 mm thick sheets in this work. Finally, the limits of deep drawing process using the finite element method with Abaqus software was studied. [ABSTRACT FROM AUTHOR]

15. Remote monitoring program in patients with pulmonary hypertension: The French experience.

Author

Fauvel, C., Jagu, A., Abdennadher, M., Esser, R., Bedel, C., Nisse Durgeat, S., and Moceri, P.

Abstract

Patients with pulmonary hypertension (PH) either pre- or post-capillary, are at high risk of mortality or morbidity (i.e., unscheduled hospitalization for acute heart failure [HF]). Remote monitoring program (RMP) is a promising solution to reduce mortality and morbidity among patients with left HF but there is actually no data regarding patients with PH, especially in patients with pre-capillary PH. Within a large cohort of patients followed by a RPM (Satelia® Cardio), to compare the main characteristics of patients with PH compared to HF patients without PH. All patients followed by RPM from January 2019 to December 2023 in France (280 centers) were included in this retrospective analysis. Patients were divided as follow: patients with left HF, regardless of left ventricular ejection fraction (LVEF), but no PH ("no PH" group), patients left HF and post-capillary PH ("post-capillary PH" group), and patients with pre-capillary PH ("pre-capillary PH" group). 15,789 patients were included in this analysis (median age was 77 (67, 85) years old, 64% of male, LVEF averaged 40 ± 10%, and the median of follow-up with telemonitoring was 12 (5, 23) months) and were distributed as follow: 15,325 (97%) in the "no PH group", 434 (2.7%) in the "post-capillary PH" group and 30 (0.3%) in the "pre-capillary PH" group. The main characteristics of the patients are summarized in the Fig. 1. Not surprisingly, patients with post-capillary PH were more likely to be aging patients with higher number of comorbidities and cardiovascular risk factors. A large majority of patients had an excellent adherence to the RMP and patients with pre-capillary PH were more likely to have higher adherence (P = 0.003). Interestingly, even if not significant, patients with pre-capillary PH were more likely to raise a telemonitoring alert and to be hospitalized at least once for AHF (P = 0.051 and mean number of hospitalization higher in pre-capillary versus post-capillary PH, P = 0.006). These results suggest that RMP adherence is high in patients with PH and suggest embedding telemonitoring into daily clinical practice, even in pre-capillary PH. More data regarding RMP impact on mortality and morbidity are now mandatory. [ABSTRACT FROM AUTHOR]
