Objective: The objective of this study was to assess outcomes and safety of consecutive neurolytic celiac plexus block (NCPB) technique.
Design: Retrospective clinical data analysis.
Setting: The study was conducted in three pain departments and academic medical center.
Patients: The subject of this study was 12 patients with terminal visceral (mostly pancreatic) cancer who failed conservative measures.
Interventions: Twelve celiac plexus alcohol neurolytic procedures were performed for pain control after a positive diagnostic block.
Materials And Methods: Twelve patients with terminal visceral (mostly pancreatic) cancer who failed conservative measures were managed by consecutive NCPB guided by computed tomography at the pain department of Beijing Xuanwu Hospital between January 2005 and June 2010. The present study evaluated the efficacy of consecutive NCPB technique with regard to pain relief, as well as its adverse effects and complications.
Results: The efficacy of consecutive NCPB technique with regard to pain relief was observed by a marked decrease in the visual analog score and in opioid consumption, with preprocedural mean values dropping from (8.7±1.0) and (155±56)mg/day of morphine to (1.8±1.1) and (0)mg/day at the first postprocedural visit, respectively. These results persisted during the 6-month follow-up period or until death. Minor adverse effects (moderate diarrhea and mild hypotension) were frequent (N=3, and N=4, respectively), and severe complications occurred in one patient with a transient paraparesis (N=1). No procedure-related mortality was observed.
Conclusions: The consecutive NCPB technique can provide analgesia and the alleviation of the secondary undesirable effects of analgesic drugs resulting from the decrease of morphine consumption in patients with upper abdominal malignancies. In the subject group, the reliability of its analgesic effect is high, with lower rate of severe complications.

Computed Tomography-guided Percutaneous Bilateral Neurolytic Celiac Plexus Block with Alcohol for Upper Abdominal Visceral Cancer Pain.

Background: The neurolytic celiac plexus block (NCPB) can be introduced through the posterior para-aortic, anterior para-aortic, posterior transaortic, or endoscopic anterior para-aortic puncture approach, as well as the posterior approach via the intervertebral disc. To reduce the complications of puncture, this block's original manual blind puncture technique can be improved upon by using a C-arm fluoroscope, computed tomography (CT), or an ultrasound, the last of which may be endoscopic.
Objective: To observe the distribution of absolute alcohol and its analgesic effect on cancer-induced upper abdominal visceral pain during percutaneous NCPB through the anterior and posterior diaphragmatic crura under CT guidance.
Early outcomes of experience warm surgery in children undergoing complete repair of tetralogy of Fallot in developing countries.

Objectives: While significant evidence supports the benefits of normothermic cardiopulmonary bypass (NCPB) over hypothermic techniques, many institutions in developing countries, including ours, continue to employ hypothermic methods. This study aimed to assess the early postoperative outcomes of normothermic cardiopulmonary bypass (NCPB) for complete surgical repair via the Tetralogy of Fallot (TOF) within our national context.
Methods: We conducted this study in the Pediatric Cardiac Intensive Care Unit (PCICU) at the University Children's Hospital.

Objectives: To determine the value of combining conventional plaque parameters and radiomics features derived from coronary computed tomography angiography (CCTA) for predicting coronary plaque progression.
Materials And Methods: Clinical data and CCTA images of 400 patients who underwent at least two CCTA examinations between January 2009 and August 2020 were analyzed retrospectively. Diameter stenosis, total plaque volume and burden, calcified plaque volume and burden, noncalcified plaque volume and burden (NCPB), pericoronary fat attenuation index (FAI), and other conventional plaque parameters were recorded.

Aim: To investigate the predictive value of the combination of DEEPVESSEL-fractional flow reserve (DVFFR) and quantitative plaque analysis using coronary computed tomographic angiography (CCTA) for major adverse cardiac events (MACE).
Method: In this retrospective study, data from 69 vessels from 58 consecutive patients were collected. These patients who underwent coronary angiography (CAG) with DVFFR were divided into MACE-positive and MACE-negative groups.

Introduction: Evidence suggests that negative cognitive processing bias (NCPB) is a significant risk factor for depression. The microbiota-gut-brain axis has been proven to be a contributing factor to cognitive health and disease. However, the connection between microbiota and NCPB remains unknown.
