Ganglion block : When and how?

[Ganglion block : When and how?] Radiologe. 2015 Sep 17; Authors: Bale R Abstract CLINICAL ISSUE: Increasing understanding of the anatomy and physiology of neural structures has led to the development of surgical and percutaneous neurodestructive methods in order to target and destroy various components of afferent nociceptive pathways. The dorsal root ganglia and in particular the ganglia of the autonomous nervous system are targets for radiological interventions. The autonomous nervous system is responsible for the regulation of organ functions, sweating, visceral and blood vessel-associated pain. STANDARD RADIOLOGICAL METHODS: Ganglia of the sympathetic chain and non-myelinized autonomous nerves can be irreversibly destroyed by chemical and thermal ablation. PERFORMANCE: Computed tomography (CT)-guided sympathetic nerve blocks are well established interventional radiological procedures which lead to vasodilatation, reduction of sweating and reduction of pain associated with the autonomous nervous system. ACHIEVEMENTS AND PRACTICAL RECOMMENDATIONS: Sympathetic blocks are applied for the treatment of various vascular diseases including critical limb ischemia. Other indications for thoracic and lumbar sympathectomy include complex regional pain syndrome (CRPS), chronic tumor associated pain and hyperhidrosis. Neurolysis of the celiac plexus is an effective palliative pain treatment particularly in patients suffering from pancreatic cancer....

Abstract Type I interferons (IFNs) facilitate cancer immunosurveillance, antitumor immunity and antitumor efficacy of conventional cell death-inducing therapies (chemotherapy/radiotherapy) as well as immunotherapy. Moreover, it is clear that dendritic cells (DCs) play a significant role in aiding type I IFN-driven immunity. Owing to these antitumor properties several immunotherapies involving, or inducing, type I IFNs have received considerable clinical attention, e.g., recombinant IFNα2 or agonists targeting pattern recognition receptor (PRR) pathways like Toll-like receptors (TLRs), cGAS-STING or RIG-I/MDA...

Abstract Dendritic cells (DCs) orchestrate a repertoire of immune responses that bring about resistance to infection and tolerance to self. Cancers can exploit DCs to evade immunity, but DCs also can generate resistance to cancer. Owing to their capacity to capture, process, and present antigens to naïve T cells, thereby launching adaptive immunity, DCs are poised to play a critical role in cancer recognition and rejection. As such, DCs represent a solution for the expansion and infiltration of T cells with tumor-rejecting properties. Indeed, clinical responses to checkpoint blockade, such as anti-PD-1, are l...

Abstract Cancer immunotherapy harnesses the ability of the immune system to recognize and eliminate cancer. The potent ability of dendritic cells (DCs) to initiate and regulate adaptive immune responses underpins the successful generation of anti-tumor immune responses. DCs are a heterogeneous leukocyte population comprised of distinct subsets that drive specific types of immune responses. Understanding how DCs induce tumor immune responses and the mechanisms adopted by tumors to evade DC surveillance is essential to render immunotherapies more effective. This review discusses current knowledge of the roles played...

(University of Vermont) Researchers at the University of Vermont's Vermont Conversation Lab have used machine learning and natural language processing to better understand what end-of-life conversations look like. Borrowing techniques used to study fiction, where machine learning algorithms analyze manuscripts to identify story types, the researchers identified several common elements in these conversations. That knowledge could eventually help healthcare practitioners understand what makes a 'good' conversation about palliative care.

Diverging RNPs: Toward Understanding lncRNA-Protein Interactions and Functions. Adv Exp Med Biol. 2019;1203:285-312 Authors: Sauvageau M Abstract RNA-protein interactions are essential to a variety of biological processes. The realization that mammalian genomes are pervasively transcribed brought a tidal wave of tens of thousands of newly identified long noncoding RNAs (lncRNAs) and raised questions about their purpose in cells. The vast majority of lncRNAs have yet to be studied, and it remains to be determined to how many of these transcripts a function can be ascribed. However, results gleaned ...
