Sex differences and clinical outcomes, including ventricular tachyarrhythmias, of patients with heart failure with reduced ejection fraction treated with sacubitril/valsartan.

Background: Women with heart failure with reduced ejection fraction (HFrEF) often experience worse clinical outcomes compared to men, including higher rates of mortality, hospitalization, and congestion. However, the effects of sacubitril/valsartan on these outcomes, as well as on ventricular tachyarrhythmias, have not been well studied in women with HFrEF.

Methods: This study included consecutive series of patients treated with sacubitril/valsartan at University Hospital Mannheim from 2016 to 2020.

The role of SNAP and WIC in the bidirectional relationship between food insecurity and maternal depressive symptoms.

Background: The association between food insecurity and maternal depressive symptoms has been established by many cross-sectional and longitudinal studies however the understanding of the reciprocal relationship between them remains unclear. Further, previous research demonstrates that federal nutrition assistance decreases food insecurity and promotes maternal mental well-being but further research is needed to elucidate the moderating role of these programs in the association between food insecurity and maternal depressive symptoms. Therefore, the current study examined the bidirectional associations between maternal depression probability and food insecurity using cross-lagged models and then tested the main and moderating effects of SNAP and WIC.

Catecholamine induces endothelial dysfunction via Angiotensin II and intermediate conductance calcium activated potassium channel.

Endothelial dysfunction contributes to the pathogenesis of Takotsubo syndrome (TTS). However, the exact mechanism underlying endothelial dysfunction in the setting of TTS has not been completely clarified. This study aims to investigate the roles of angiotensin II (Ang II) and intermediate-conductance Ca-activated K (SK4) channels in catecholamine-induced endothelial dysfunction.

Influence of the spaceflight environment on macrophage lineages.

Spaceflight and terrestrial spaceflight analogs can alter immune phenotypes. Macrophages are important immune cells that bridge the innate and adaptive immune systems and participate in immunoregulatory processes of homeostasis. Furthermore, macrophages are critically involved in initiating immunity, defending against injury and infection, and are also involved in immune resolution and wound healing.

[Treatment with cardiac electronic implantable devices].

Cardiac device therapy provides not only treatment options for bradyarrhythmia but also advanced treatment for heart failure and preventive measures against sudden cardiac death. In heart failure treatment it enables synergistic reverse remodelling and reduces pharmacological side effects. Cardiac resynchronization therapy (CRT) has revolutionized the treatment of reduced left ventricular ejection fraction (LVEF) and left bundle branch block by decreasing the mortality and morbidity with improvement of the quality of life and resilience.
