Association of carbon monoxide poisoning with cardiovascular disease risk: A systematic review and meta-analysis.

Objective: This study aims to provide an updated overview of the relationship between carbon monoxide poisoning (COP) and cardiovascular disease. Methods: A systematic literature search was conducted in PubMed, Embase, Cochrane, and Web of Science databases up to September 2023. The association between COP patients and cardiovascular adverse events was examined and summarized. The outcomes included arrhythmia, coronary heart disease, heart failure, myocardial infarction, major adverse cardiovascular events (MACE), carboxyhaemoglobin percent (COHB%), Pondus Hydrogenii (PH) electrocardiography (ECG) parameters. Results: Eight eligible articles, involving a total of 251,971 patients, were included for evidence synthesis. The analysis revealed a heightened incidence of MACE in patients with COP. Additionally, COP exhibited an impact on specific ECG parameters. The incidence of MACE after COP was found to be similar in Korean and Chinese populations, and there was no significant effect of gender or underlying diseases on MACE incidence following COP. The incidence of MACE after COP did not differ significantly in individuals aged 50 years and older. Conclusions: Considering the observed heterogeneity and potential biases in the selected studies, emergency physicians should be aware of the increased likelihood of cardiovascular events in patients diagnosed with COP.

Prognostic value of plasma diquat concentration in patients with acute oral diquat poisoning: a retrospective study.

Objectives: Diquat poisoning is an important public health and social security agency. This study aimed to develop a prognostic model and evaluate the prognostic value of plasma diquat concentration in patients with acute oral diquat poisoning, focusing on how its impact changes over time after poisoning. Methods: This was a retrospective cohort study using electronic healthcare reports from the Second Hospital of Hebei Medical University. The study sample included 80 patients with acute oral Diquat poisoning who were admitted to the hospital between January 2019 and May 2022. Time-to-event analyses were performed to assess the risk of all-cause mortality (30 days and 90 days), controlling for demographics, comorbidities, vital signs, and other laboratory measurements. The prognostic value of plasma DQ concentration on admission was assessed by computing the area under a time-dependent receiver operating characteristic curve (ROC). Results: Among the 80 patients, 29 (36.25%) patients died, and 51 (63.75%) patients survived in the hospital. Non-survivors had a median survival time (IQR) of 1.3(1.0) days and the longest survival time of 4.5 days after DQ poisoning. Compared with non-survivors, survivors had significantly lower amounts of ingestion, plasma DQ concentration on admission, lungs injury within 24 h after admission, liver injury within 24 h after admission, kidney injury within 24 h after admission, and CNS injury within 36 h after admission, higher APACHE II score and PSS within 24 h after admission (all p < 0.05). Plasma Diquat concentration at admission (HR = Exp (0.032-0.059 × ln (t))) and PSS within 24 h after admission (HR: 4.470, 95%CI: 1.604 ~ 12.452, p = 0.004) were independent prognostic factors in the time-dependent Cox regression model. Conclusion: Plasma DQ concentration at admission and PSS within 24 h after admission are independent prognostic factors for the in-hospital case fatality rate in patients with acute oral DQ poisoning. The prognostic value of plasma DQ concentration decreased with time.

Identification and validation of lipid metabolism-related key genes as novel biomarkers in acute myocardial infarction and pan-cancer analysis.

BACKGROUND: Acute myocardial infarction (AMI) is associated with high morbidity and mortality, and is associated with abnormal lipid metabolism. We identified lipid metabolism related genes as biomarkers of AMI, and explored their mechanisms of action. METHODS: Microarray datasets were downloaded from the GEO database and lipid metabolism related genes were obtained from Molecular Signatures Database. WGCNA was performed to identify key genes. We evaluated differential expression and performed ROC and ELISA analyses. We also explored the mechanism of AMI mediated by key genes using gene enrichment analysis. Finally, immune infiltration and pan-cancer analyses were performed for the identified key genes. RESULTS: TRL2, S100A9, and HCK were identified as key genes related to lipid metabolism in AMI. Internal and external validation (including ELISA) showed that these were good biomarkers of AMI. In addition, the results of gene enrichment analysis showed that the key genes were enriched in inflammatory response, immune system process, and tumor-related pathways. Finally, the results of immune infiltration showed that key genes were concentrated in neutrophils and macrophages, and pan-cancer analysis showed that the key genes were highly expressed in most tumors and were associated with poor prognosis. CONCLUSIONS: TLR2, S100A9, and HCK were identified as lipid metabolism related novel diagnostic biomarkers of AMI. In addition, AMI and tumors may be related through the inflammatory immune response.

Food-Borne Poisoning Accident from Amanitin Toxin in Wild Mushrooms - Xingtai City, Hebei Province, China, 2023.

What is already known about this topic?: Fatal poisonings caused by wild mushrooms containing amanita toxins pose a significant threat in the southern regions of China. These toxins primarily induce gastrointestinal symptoms initially, which are then followed by potentially life-threatening acute liver damage. What is added by this report?: This report contributes to the existing knowledge on these cases of poisoning by documenting the second occurrences in Hebei Province and the first occurrences in Xingtai City. Five individuals reported consuming wild mushrooms from the same origin, and laboratory tests confirmed the presence of α-amanitin in their blood samples. What are the implications for public health practice?: This underscores the risk associated with the collection and consumption of amanita toxin-containing mushrooms in Hebei. It is important to note that the identification of toxic and non-toxic mushrooms should not solely rely on personal experience or appearance.

Cardiogenic shock as the initial manifestation of systemic lupus erythematosus.

Cardiogenic shock as the initial manifestation of systemic lupus erythematosus (SLE) is an uncommon but catastrophic complication. Because of the lack of typical clinical features, the diagnosis of the disease is challenging. This case report describes a 47-year-old female admitted to the emergency room in refractory cardiogenic shock with dilative cardiomyopathy and a left ventricular ejection fraction (LVEF) of 25.6% of unknown origin. The patient responded poorly to the initial tries of stabilization, and the clinical status continued to deteriorate. Venous-arterial extracorporeal membrane oxygenation (V-A ECMO) was applied to maintain hemodynamic stability. Coronary angiography revealed no obvious stenosis of the coronary artery. Evidence of virus infection was negative. After requestioning about medical history in detail, Reynaud's phenomenon was shown. SLE was suspected. A complete autoimmune laboratory workup was completed and found the positive result of antinuclear antibodies, anti-double-stranded DNA antibodies, anti-phospholipid antibodies, and low C3 and C4. The patient also presented with pericardial effusion and the PLTs <100 000/mm3 . SLE was confirmed according to the 2019 EULAR/ACR criteria. When the diagnosis was established, the immunotherapy was initiated. As a result, the patient underwent a quick recovery and achieved good outcomes. In conclusion, early diagnosis and timely application of immunotherapy is the key to treatment lupus myocarditis. Advanced mechanical support may play a necessary role when patient is in critical situation. For middle-aged female patients presenting with unexplained cardiogenic shock, lupus myocarditis should be considered in the differential diagnosis. In addition, the 2019 EULAR/ACR criteria provide a new, fitting tool for the diagnosis, which is conducive to the earlier and more accurate diagnosis of SLE.
