Posthemorrhagic shock mesenteric lymph (PHSML) return-contributed excessive autophagy of vascular smooth muscle cells (VSMCs) is involved in vascular hyporeactivity, which is inhibited by stellate ganglion block (SGB) treatment. The contractile phenotype of VSMCs transforms into a synthetic phenotype after stimulation with excessive autophagy. Therefore, we hypothesized that SGB ameliorates PHSML-induced vascular hyporeactivity by inhibiting autophagy-mediated phenotypic transformation of VSMCs. ⋯ The results showed that PHSML, but not PHSML-SGB, incubation decreased VSMC contractility and induced autophagy activation and phenotype transformation. Importantly, 3-MA administration reversed the adverse effects of PHSML, and RAPA treatment attenuated the effects of PHSML-SGB incubation on VSMCs. Taken together, the protective effect of SGB on vascular reactivity is achieved by inhibiting excessive autophagy-mediated phenotypic transformation of VSMCs to maintain their contractile phenotype.

Background: Treatment of acute compartment syndrome (ACS)-induced skeletal muscle injury remains a challenge. Previous studies have shown that octanoic acid is a promising treatment for ACS owing to its potential ability to regulate metabolic/epigenetic pathways in ischemic injury. The present study was designed to investigate the efficacy and underlying mechanism of octanoic acid in ACS-induced skeletal muscle injury. ⋯ Lastly, we found NaO treatment exerts a stimulatory impact on the activation of the AMPK pathway, thus promoting mitophagy and improving mitochondrial dynamics. Conclusion: Our findings indicate that octanoic acid may ameliorate skeletal muscle injury induced by ACS. Its protective effects may be attributed to the promotion of acetyl-CoA synthesis and histone acetylation within the muscular tissue, as well as its activation of the AMPK-related mitophagy pathway.

[Current therapeutic standards in advanced soft tissue sarcomas].
Soft tissue sarcomas account for less than 1% of tumors in adults. With more than 80 different subtypes and often dismal prognosis, treatment of patients with soft tissue sarcomas is diagnostically and therapeutically complex. In patients with localized disease, surgery remains the mainstay of therapy. ⋯ In patients with disseminated metastatic disease, chemotherapy with anthracyclines remains the backbone of therapy. Immune checkpoint inhibitors have proven to be effective for patients with alveolar soft part sarcoma and targeted therapies with NTRK-inhibitors should be evaluated in patients with NTRK-fusions. This article focuses on current standards and developments in the treatment of soft tissue sarcomas.

[Rheumatoid arthritis: Appraisement of the new security warnings for JAK-inhibitors].
Januskinase-Inhibitors (JAKI) are highly effective substances (JAKi) for the treatment of rheumatoid arthritis (RA). In terms of efficiency in reduction of disease activity and induction of remission they are partially prior to biologic (b) DMARDs. Presently the four substances tofacitinib, baricitinib, upadacitinib and filgotinib are approved for the treatment of RA. ⋯ On the basis of this trial the Committee for Medical Products for Human Use (CHMP) of the European Medicines Agency (EMA) formulated actual recommendations for prescription of JAKi in order to reduce the risk of severe undesirable effects. These apply not only for tofacitinib but as well for all other JAKI named above, as a class effect was supposed. The data and their consequences are discussed and evaluated in this work.

[Atrial fibrillation in the elderly - the geriatric perspective].
Atrial fibrillation is the most common cardiac arrhythmia in older adults. As a result of the positive data on ablation, the focus has shifted to rhythm control. The method of choice is pulmonary vein isolation. ⋯ Oral anticoagulation remains an essential component of pharmacological therapy for atrial fibrillation. Older adults require an individualised treatment approach, which should be based on current guidelines and complementary tools. The assessment of functionality should be taken into account in therapy and goal planning.
