Preoperative Transient Elastography in Patients with Esophageal Cancer. Diagnostics (Basel) 2022; 12:diagnostics12123194. [PMID: 36553201 PMCID: PMC9777419 DOI: 10.3390/diagnostics12123194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 12/09/2022] [Accepted: 12/11/2022] [Indexed: 12/23/2022] Open
Abstract
Since excessive alcohol consumption is a shared risk factor for esophageal cancer and liver fibrosis, it is possible that patients with esophageal cancer may develop unknown liver fibrosis or cirrhosis. We applied preoperative transient elastography (TE) to patients without recorded cirrhosis undergoing esophagectomy to clarify the validity in predicting postesophagectomy hepatic failure. The cohort consisted of 107 patients who received TE before esophagectomy between June 2018 and December 2021. Patients were categorized into two groups based on the fibrosis score yielded by preoperative TE (mild group: 0~2, n = 92; severe group: 3~4, n = 15). There was no significant difference in demographic data nor surgical variables between the two groups. None of the cohort encountered hepatic failure, yet the severe fibrosis group had a significantly higher rate of pleural effusion (40.0% versus 15.2%, p = 0.03). The areas under the curve (AUCs) of TE in predicting postoperative complications and 180-day mortality were 0.60 (95% CI: 0.46-0.74) and 0.67 (95% CI: 0.51-0.83), respectively. In conclusion, stratification of patients with esophageal cancer who had liver fibrosis by preoperative TE demonstrates significant validity in predicting postoperative pleural effusions. Recruitment of noncirrhotic patients with higher TE scores is warranted to examine its power in other parameters.

Sci Rep 2022; 12:17132. [PMID: 36224357 PMCID: PMC9556518 DOI: 10.1038/s41598-022-22186-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2022] [Accepted: 10/11/2022] [Indexed: 01/04/2023] Open
Abstract
Penetrating abdominal injury is a major cause of death in trauma. Sodium alginate hydrogel, a hemostatic agent, offers a platform for targeting both mechanical and biological injuries. The current study assessed the effect of Very Low Viscosity (high) G (VLVG) alginate following abdominal trauma in a swine model of penetrating abdominal injury. Seven anesthetized pigs were instrumented with invasive monitoring catheters and abdominal trauma was introduced by laparoscopic hepatectomy. Ten minutes after the induction of hypovolemic shock, three animals were intra-abdominally administered with VLVG alginate (study group) and four animals with saline (control group). During 8 h of continuous monitoring, various hemodynamic and biochemical variables were measured and liver biopsies for histological evaluation were taken. Hemodynamically, VLVG alginate-treated animals were more stable than controls, as reflected by their lower heart rate and higher blood pressure (p < 0.05 for both). They also had lower levels of liver enzymes and lactate, and less histopathological damage. We show that VLVG alginate might be a promising new agent for reducing penetrating intra-abdominal injury, with hemostatic and biocompatibility efficiency, and tissue preserving properties. Future effort of integrating it with a dispersal device may turn it into a valuable pre-hospital emergency tool to improve survival of trauma casualties.

Abstract
Prunella vulgaris is a widely used edible Chinese medicinal plant. In the present study, two new abietane-type diterpenoids, abietoquinones A (1) and B (2), were isolated from this plant by an immunosuppressive bioassay-guided isolation procedure. Their structures were elucidated unambiguously by NMR spectroscopic analysis, single-crystal X-ray crystallography, and electronic circular dichroism calculations. Compounds 1 and 2 bear a cyclohex-2-ene-1,4-dione moiety, which is uncommon among abietane diterpenes. Also, abietoquinone A (1) suppressed murine splenocyte proliferation and decreased the production of proinflammatory cytokines induced by concanavalin A (Con A) in vitro. In Con A-challenged mice, preinjection with 1 significantly ameliorated liver injury. Additionally, abietoquinone A (1) exhibited inhibitory activities against the proliferation of murine splenocytes and human T cells induced by anti-CD3/anti-CD28 monoclonal antibodies (mAbs).

Abstract
Varioxepine B (1), an oxepine-containing diketopiperazine derivative, was isolated from a marine-derived Aspergillus terreus strain. The structure of 1 was identified by spectroscopic experiments, single-crystal X-ray diffraction analysis, and electronic circular dichroism calculations. It is noteworthy that 1 could suppressed murine splenocyte proliferation activated by concanavalin A (Con A) in vitro. More importantly, in Con A-challenged mice, pretreatment with 1 obviously decreased the generation of proinflammatory cytokines and ameliorated liver injury. Meanwhile, 1 also exhibited inhibitory activity in anti-CD3/anti-CD28 monoclonal antibodies (mAbs)-induced murine splenocytes and human T cell proliferation as well as both Th1 and Th2 cytokine production.

Abstract
Diagnostic imaging relies on interpretation of interactions between the body tissue and various energies, such as x-rays, ultrasound, and magnetic or nuclear energies, to differentiate normal from abnormal tissues. Major technological improvements regarding emission and detection of the energetic waves, as well as reconstruction and interpretation of the images, have occurred. These advances made possible visualization of smaller structures, quantitative evaluation of functional processes, and development of unique imaging-guided procedures. This article reviews the technological advances that allowed development of cone beam computed tomography, dual-energy x-ray absorptiometry, and contrast-enhanced ultrasonography, which all could have applications in exotic pet medicine.

Combination of liver enzymes, amylase and abdominal ultrasound tests have acceptable diagnostic values as an alternative test for abdominopelvic CT scan in blunt abdominal trauma. Open Access Emerg Med 2019; 11:205-210. [PMID: 31686923 PMCID: PMC6709808 DOI: 10.2147/oaem.s207066] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Accepted: 08/05/2019] [Indexed: 11/23/2022] Open
Abstract
Introduction Abdominal trauma accounts for 15–20% of all-cause mortality of trauma. Abdominopelvic CT scan with intravenous contrast is considered the most accurate non-invasive diagnostic tool in detecting intra-abdominal injuries. In previous studies, rise in liver enzymes and amylase was associated with intra-abdominal injuries but the studies were not sufficient. Our aim was to assess the diagnostic values of liver enzymes and amylase for intra-abdominal injuries in blunt trauma patients. Methods We included blunt abdominal trauma patients who referred to three teaching hospitals in 2018. The patients who had 14 years old or more and Glasgow Coma Scale above 8 were enrolled the study if the treating physician had high index of suspicion for intra-abdominal injuries and sent the patients for abdominopelvic CT scan with intravenous contrast. Sensitivity, specificity, positive and negative predictive values are calculated for results of liver enzymes, amylase and abdominal ultrasound. Results Eventually, 300 patients with blunt abdominal trauma entered the study. Sensitivity, specificity, positive and negative predictive values of concurrent positive results of abdominal ultrasound, amylase and liver enzymes were 81.73 (95% CI, 73.2–88.1), 63.78 (95% CI, 65.36–70.61), 58.38 (95% CI, 56.36–70.61) and 84.89 (95% CI, 77.6–90.19), respectively. Conclusion Considering findings of the present study, the combination of liver enzymes, amylase and abdominal ultrasound results can be an alternative method for detecting intra-abdominal injuries in patients in whom treating physicians have limitations such as overweight, instability of hemodynamic and lack of CT scan facility.
