Nomogram model for predicting secondary infection in critically ill patients with heatstroke: A pilot study from China.

Objective: In this retrospective analysis, we explored the clinical characteristics and risk factors of secondary infections in patients with severe heatstroke with the aim to gain epidemiological insights and identify risk factors for secondary infections.

Method: The study included 129 patients with severe heatstroke admitted to the General Hospital of the Southern Theater Command of the PLA between January 1, 2011, and December 31, 2021. Patients were divided into an infection group (n = 24) and a non-infection group (n = 105) based on infection occurrence within 48 h of intensive care unit (ICU) admission.

A NOMOGRAM BASED ON THE VALUE OF THE DYNAMIC EVOLUTION OF SYSTEMIC IMMUNE INFLAMMATORY INDEX IN THE EVALUATION OF SEVERE HEATSTROKE.

Background : Severe heatstroke patients have a poor prognosis. There are few descriptions of the inflammatory response to heatstroke in clinical studies. Systemic immune-inflammation index (SII) is a new index to reflect the inflammatory state of disease.

Risk factors for and outcomes of heatstroke-related intracerebral hemorrhage.

Some patients with heatstroke also experience intracerebral hemorrhage (ICH). However, clinical case reports of heatstroke-induced ICH are rare. The risk factors for cerebral hemorrhage after heatstroke remain unknown.

Decompression sickness followed by diabetic ketoacidosis and sepsis shock: an unusual case report.

Decompression sickness (DCS) is caused by abrupt changes in extracorporeal pressure with varying severity. Symptoms range from mild musculoskeletal pain to severe organ dysfunction and death, especially among patients with chronic underlying disease. Here, we report an unusual case of a 49-year-old man who experienced DCS after a dive to a depth of 38 meters.

Hepatic portal venous gas initially manifesting as severe shock: a case series.

Hepatic portal venous gas is often referred to as the "sign of death" because it signifies a very poor prognosis if appropriate treatments are not promptly administered. The etiologies of hepatic portal venous gas are diverse and include severe complex abdominal infections, mesenteric ischemia, diving, and complications of endoscopic surgery, and the clinical manifestations are inconsistent among individual patients. Thus, whether emergency surgery should be performed remains controversial.

Non-Invasive and Label-Free On-Chip Impedance Monitoring of Heatstroke.

Heatstroke (HS) is a life-threatening injury requiring neurocritical care which could lead to central nervous system dysfunction and severe multiple organ failure syndrome. The cell-cell adhesion and cell permeability are two key factors for characterizing HS. To investigate the process of HS, a biochip-based electrical model was proposed and applied to HS.

ROS/JNK-mediated lysosomal injury in rat intestinal epithelial-6 cells during heat stress.

Injury to the intestinal epithelial cells and loss of the intestinal barrier are critical to heatstroke. To reveal the mechanism through which heatstroke leads to intestinal epithelial injury, the relationship between reactive oxygen species (ROS), c-Jun NH2-terminal kinase (JNK), and lysosomes were studied in intestinal epithelial cells subjected to heat stress. Cells of heat stress groups were incubated at 43 °C for 1 h, then incubated at 37 °C as indicated.

Method: This retrospective study compared the clinical characteristics of two LAARs poisoning patients and used multivariate regression method to explore the relationship between blood LAAR concentration and vitamin K1 dose/treatment time.

Actively implementing an evidence-based feeding guideline for critically ill patients (NEED): a multicenter, cluster-randomized, controlled trial.

Background: Previous cluster-randomized controlled trials evaluating the impact of implementing evidence-based guidelines for nutrition therapy in critical illness do not consistently demonstrate patient benefits. A large-scale, sufficiently powered study is therefore warranted to ascertain the effects of guideline implementation on patient-centered outcomes.

Methods: We conducted a multicenter, cluster-randomized, parallel-controlled trial in intensive care units (ICUs) across China.

Impact of the gut microbiota on heat stroke rat mediated by Xuebijing metabolism.

The goal of the present study was to evaluate the fecal microbiome and serum metabolites in Xuebijing (XBJ)-injected rats after heat stroke using 16S rRNA gene sequencing and gas chromatography-mass spectrometry (GC-MS) metabolomics. Eighteen rats were divided into the control group (CON), heat stroke group (HS), and XBJ group. The 16S rRNA gene sequencing results revealed that the abundance of Bacteroidetes was overrepresented in the XBJ group compared to the HS group, while Actinobacteria was underrepresented.

Xuebijing attenuates hypotension through the upregulation of angiotensin II type 1 receptor-associated protein 1 in rats suffering from heat stroke.

In our previous study, we demonstrated that Xuebijing (XBJ), a traditional Chinese medicine, attenuates hypotension in rats suffering from heatstroke (HS). However, the underlying mechanisms have not yet been fully elucidated. Thus, the current study was carried out to investigate the mechanisms underlying the effects of XBJ on hypotension n rats suffering from HS.

Inhibitory effects of resveratrol on foam cell formation are mediated through monocyte chemotactic protein-1 and lipid metabolism-related proteins.

Resveratrol has been shown to exert anti-atherosclerotic effects. 5' AMP-activated protein kinase (AMPK) and monocyte chemotactic protein-1 (MCP-1) play key roles in foam cell formation, which is considered as the initiation of atherosclerosis. Thus, in this study, we investigated whether resveratrol inhibits foam cell formation by regulating lipid accumulation and inflammation.

Resveratrol ameliorates subacute intestinal ischemia-reperfusion injury.

Background: Resveratrol has been shown to attenuate reactive oxygen species formation and protect against ischemia-reperfusion (I/R) injury. However, the effects of resveratrol against subacute intestinal I/R injury are not clearly elucidated. Therefore, this study was designed to investigate the effects and possible protective mechanisms of resveratrol on subacute intestinal I/R injury in mice.

Osthole, a bioactive simple coumarin derivative extracted from a number of medicinal plants, such as Cnidium monnieri and Angelica pubescens, has been shown to exert a variety of pharmacological activities and is considered to have potential therapeutic applications. In this study, we investigated the protective effects of osthole against myocardial ischemia/reperfusion (I/R) injury in rats. Male Sprague-Dawley rats were randomly assigned to 1 of 5 groups: the sham-oeprated control group (control), the vehicle group (vehicle), and 3 treatment groups, which were treated with osthole at the concentration of 1, 10 or 50 mg/kg (intraperitoneally), respectively, upon the initiation of myocardial ischemia.

SKF-96365 attenuates toxin-induced neuronal injury through opposite regulatory effects on Homer1a and Homer1b/c in cultured rat mesencephalic cells.

Disturbances in Ca(2+) homeostasis have been implicated in a variety of neuro-pathological conditions including Parkinson's disease (PD). In the present study, we investigated the potential protective effect of SKF-96365, an originally identified blocker of receptor-mediated calcium entry, on MPP(+) induced neuronal injury in cultured rat mesencephalic cells. We found that pretreatment with SKF-96365 30 min before injury significantly reduced nuclear damage, decreased LDH release and inhibited apoptotic neuronal death.
