Introduction: The association between elevated lactate levels and the development of disseminated intravascular coagulation (DIC) in patients with severe trauma remains unclear. Hence, this study aimed to explore the association between lactate and the development of DIC in patients with severe trauma.
Methods: This prospective cohort study was conducted on consecutive patients with severe trauma who were hospitalized in the intensive care unit from January 2020 to January 2023. The primary outcome measured was the occurrence of DIC in patients in the emergency department or posthospitalization. Logistic regression analysis evaluating the risk values for lactate and DIC, the receiver operating characteristic (ROC) curve, and decision curve analysis (DCA) examinations studying the predictive efficiency of lactate for DIC. The Kaplan-Meier survival curve was used to assess patient survival. Sensitivity robustness analysis included modified Poisson regression, -value, subgroup analysis, and numerical variable transformation analysis.
Results: Logistic regression analysis corrected for confounding factors showed that lactate was a risk factor for DIC in patients with severe trauma (adjusted odds ratio [OR]: 1.374, 95% confidence interval [CI]: 1.206-1.566). Lactate predicted DIC risk with a 0.8513 area under the ROC curve (95% CI: 0.7827-0.9199), 4.8 cutoff value, 0.8333 sensitivity, and 0.8014 specificity. DCA showed the correlation between lactate and DIC. The mortality rate of patients with a high risk of DIC was significantly higher than that of patients with a low risk (log-rank test, < 0.001). The modified Poisson regression showed that lactate was a risk factor for DIC (risk ratio: 1.188, 95% CI: 1.140-1.237). -value was 1.645, and the lower limit of 95% CI was 1.495. The logistic regression analysis after subgroup analysis and transformation of numerical variables showed that lactate remained a risk factor for DIC.
Conclusions: Elevated lactate is closely associated with the occurrence of DIC in patients with severe trauma. Lactate seems to be a good predictive factor for DIC manifestation in patients with severe trauma.

Context: The injuries caused by falls-from-height (FFH) are a significant public health concern. FFH is one of the most common causes of polytrauma. The injuries persist to be significant adverse events and a challenge regarding injury severity assessment to identify patients at high risk upon admission.

Idiopathic Pulmonary Fibrosis (IPF) is a chronic respiratory disorder for which pirfenidone is the recommended first-line anti-fibrotic treatment. While pirfenidone has demonstrated efficacy in slowing the progression of IPF, its use is associated with several challenges and unresolved issues that impact patient outcomes. Pirfenidone administration can result in gastrointestinal side effects, photosensitivity reactions, and significant drug interactions, particularly in patients with hepatic impairment.

Background: Primary ciliary dyskinesia (PCD) is a rare autosomal recessive disorder characterized by dysfunction of motile cilia. While approximately 50 genes have been identified, around 25% of PCD patients remain genetically unexplained; elucidating the pathogenicity of specific variants remains a challenge.
Methods: Whole exome sequencing (WES) and Sanger sequencing were conducted to identify potential pathogenic variants of PCD.

Purpose: Epicardial adipose tissue (EAT) could contribute to the specific atherosclerosis profile observed in premature coronary artery disease (pCAD) characterized by accelerated plaque burden (calcified and non-calcified), high risk plaque features (HRP) and ischemic recurrence. Our aims were to describe EAT volume and density in pCAD compared to asymptomatic individuals matched on CV risk factors and to study their relationship with coronary plaque severity extension and vulnerability.
Materials And Methods: 208 patients who underwent coronary computed tomography angiography (CCTA) were analyzed.

Despite significant advancements in achieving high recanalization rates (80%-90%) for large vessel occlusions through mechanical thrombectomy, the issue of "futile recanalization" remains a major clinical challenge. Futile recanalization occurs when over half of patients fail to experience expected symptom improvement after vessel recanalization, often resulting in severe functional impairment or death. Traditionally, this phenomenon has been attributed to inadequate blood flow and reperfusion injury.
