The N-ethylmaleimide-sensitive fusion protein attachment protein receptor YKT6 is a key protein that controls the release of exosomes, was reported to play important roles in multiple cancers. However, the role of YKT6 in hepatocellular carcinoma (HCC) is still unknown.

Here we first used bioinformatics tools to analyze the
mRNA expression in HCC. In addition, we retrospectively collected 330 cancer tissue specimens from HCC patients and 180 para-cancerous tissue specimens, and detected YKT6 expression using immunohistochemical staining. Then the relationship between YKT6 expression and the clinical characteristics of HCC was analyzed, Kaplan-Meier analysis and Cox regression model were also performed to evaluate the impact of YKT6 expression on prognosis of HCC. Protein-protein interaction network of YKT6, and the gene enrichment analysis (GSEA) database were used to predict possible signal pathways regulated by YKT6 in HCC.

The high expression rate of YKT6 in HCC (72.40%, 239/330) was higher than tr invasion (p = .005), AFP level (p = .002). Kaplan-Meier survival analysis showed that HCC patients with high YKT6 expression level had poorer prognosis. Meanwhile, multivariate Cox regression analysis showed that Edmondson grade (p = .009), metastasis (p = .049), YKT6 expression (p = .037) are independent risk factors for poor prognosis of HCC. Conclusions Our results suggested that the upregulated expression of YKT6 is closely related to the progression HCC, which may be used as a potential biomarker for poor prognosis in HCC.
Scombroid syndrome constitutes a toxic illness caused by ingestion of improperly stored fish, usually contaminated by Gram-negative bacteria producing histamine and other toxins. Scombroid currently accounts for approximately 5% of food toxicities in the United States. Though cardiovascular complications are infrequent, some patients experienced acute coronary syndrome (ACS) on admission to hospital. This article focuses on the main pathophysiology, clinical features, therapy, and outcomes in scombroid-related ACS.

Starting from the consolidated knowledge on histaminergic syndromes, we performed a literature search for studies describing patient series and single cases presenting at emergency department with scombroid toxicity complicated by myocardial ischemia.

After a pathophysiological overview on histaminergic syndromes, we carefully analyzed a dataset of 19 patients from 13 studies, published from 1997 to December 2020. Electrocardiographic, echocardiographic, angiographic features, clinical course, hospital complications, and therapeutic approach were described. Shared and differential aspects of scombroid ACS with typical atherosclerotic ischemia, Kounis, MINOCA and Takotsubo syndromes are also discussed.

An ischemic heart scombroid syndrome may occur in some patients after the eating of improperly stored fish food. Currently available studies indicate this as a benign condition, except for patients with history of coronary artery disease, previous ACS, or anaphylaxis. Of clinical concern, there is a potential of hemodynamic failure in the acute stage, even in apparently healthy people.

Dexamethasone has been suggested for the prevention of PONV. The aim of the present study was to evaluate the efficacy of dexamethasone as an anti-emetic and analgesic following total abdominal hysterectomy. The study was performed as a double blind, placebo-controlled randomised clinical trial on 102 women undergoing an open total abdominal hysterectomy. The intervention group received 8 mg dexamethasone 1 h before surgery, and the control group received a placebo. The total number of emesis episodes during the 24 h after surgery did not show significant difference between the two groups, however, the number of emesis episodes in hours 2 and 4 after the surgery were less in the intervention group, but not in hours 0, 6, 12 and 24. The nausea severity in hours 0, 2, 4, 6 and 12 after the surgery, was less in the intervention group. The severity of pain was not different between the two groups.IMPACT STATEMENTWhat is already known on this subjecthasone. Also, dexamethasone, 8 mg, cannot be considered for pain relief after an open total abdominal hysterectomy. Higher amounts of dexamethasone should be evaluated for this purpose, in order to find appropriate dosages.
Poisoning may lead to respiratory failure, shock, cardiac arrest, or death. Extracorporeal membrane oxygenation (ECMO) may be used to provide circulatory support, termed venoarterial (VA) ECMO; or respiratory support termed venovenous (VV) ECMO. The clinical utility of ECMO in poisoned patients remains unclear and guidelines on its use in this setting are lacking.

To perform a literature search and narrative review on the use of ECMO in poisonings. Additionally, to provide recommendations on the use of ECMO in poisonings from physicians with expertise in ECMO, medical toxicology, critical care, and emergency medicine.

A literature search in Ovid MEDLINE from 1946 to October 14, 2020, was performed to identify relevant articles with a strategy utilizing both MeSH terms and adjacency searching that encompassed both extracorporeal life support/ECMO/Membrane Oxygenation concepts and chemically-induced disorders/toxicity/poisoning concepts, which identified 318 unique records. Twelve additional manuscripts wratory failure. Future studies may help to further our understanding of the use and complications of ECMO in poisoned patients.
ECMO may provide hemodynamic or respiratory support to poisoned patients while they recover from the toxic exposure and metabolize or eliminate the toxic agent. Available literature suggests a potential benefit for ECMO use in selected poisoned patients with refractory shock, cardiac arrest, or respiratory failure. Future studies may help to further our understanding of the use and complications of ECMO in poisoned patients.
To develop a novel inhalation exposure system capable of delivering a controlled inhaled HD dose through an endotracheal tube to anesthetized rats to investigate the lung pathophysiology and evaluate potential medical countermeasures.

Target HD vapor exposures were generated by a temperature-controlled vapor generator, while concentration was monitored near real-time by gas chromatography. see more Animal breathing parameters were monitored real-time by in-line EMKA/SciReq pulmonary analysis system. Individual exposures were halted when the target inhaled doses were achieved. Animals were observed daily for clinical observations and lethality with scheduled termination at 28 days post-exposure. Upon scheduled or unscheduled death, animals underwent a gross necropsy and lung and trachea were collected for histopathology.

Controlled HD concentrations ranged from 60 to 320 mg/m
. Delivered inhaled doses range from 0.3 to 3.20 mg/kg with administered doses within 3% of the target. The 28-day inhaled LD
is 0.80 mg/kg (95% CI = 0.42-1.18 mg/kg). Post exposure respiratory abnormalities were observed across all dose levels though the higher dose levels had earlier onset and higher frequency of occurrence. Histopathologic alterations were not qualitatively altered in accordance with dose but instead showed a relationship to an animals' time of death, with early deaths demonstrating acute damage and later deaths displaying signs of repair.

This novel exposure system administers targeted HD inhaled doses to generate a small animal model that can be used to evaluate physiological toxicities of inhaled HD on the lungs and for evaluation of potential medical countermeasure treatments.

Maternal and fetal outcomes in pregnant patients with autoimmune hepatitis (AIH) has been largely unexplored.

This meta-analysis aims to determine the level of evidence associated with both maternal and fetal outcomes in patients with AIH.

We conducted a comprehensive literature search. The studies included AIH patients who had at least one pregnancy with a previously known or index presentation diagnosis of AIH. We used a random-effects model using odds ratios (OR) with 95% confidence intervals (CI).

Fourteen studies with 1452 AIH patients and with a total of 1556 gestations were included. Analysis revealed statistically significant increased likelihood of diabetes mellitus in the AIH group (OR 5.73, 95% CI 2.73-12.02;
 < .001,
 = 2) compared to controls. Fetal outcomes that indicated a statistically significant association with AIH included premature birth (OR 2.20, 95% CI1.66-2.91;
 < .001,
 = 3), small for gestational age (SGA) births (OR 2.48, 95% CI1.37-4.51;
 = .003,
 = 2) andntial decrease in full term birth compared to normal controls. This data is important for clinicians managing these patients before, during and after pregnancy.
To explore the feasibility of microwave ablation (MWA) of the vertebral growth plate as a minimally invasive treatment for early-onset scoliosis.

One side of the L1-L3 vertebral growth plates were ablated using different MWA powers. Ablation safety and size were examined. Subsequently, L1-L3 vertebral growth plates were ablated on one side for 40 s at 20 W. At 2, 4, and 6 weeks after the ablation, growth changes of the spine were observed.

No piglets died during and after ablation, and all had modified Tarlov Grade 5. The safe MWA time (time for safely ablating the vertebral growth plate) was 17.0 ± 1.5 s at 50 W, 23.0 ± 2.3 s at 40 W, 31.0 ± 3.1 s at 30 W, 47.0 ± 3.7 s at 20 W, 70.0 ± 4.2 s at 15 W, and 158.0 ± 5.0 s at 10 W. With power <15 W, the vertebral growth plate could not be effectively ablated within the safe ablation time. Within the safe ablation times, the MWA size on hematoxylin and eosin slices on a transverse diameter was between 7 and 10 mm; and that on longitudinal diameter was mainly determined by the ablation needle length. Moreover, the growth plate and annulus fibrosus on the ablated side grew poorly over time, the vertebral body showed significant wedge-shaped changes, and the spine showed significant unbalanced growth.

MWA of the vertebral growth plate can be performed safely when accompanied with appropriate thermometry, and could be a new minimally invasive strategy in regulating spine growth.
