To investigate the diagnostic value of a novel high-sensitivity urine lipoarabinomannan (LAM) test (chemiluminescence-based) for active tuberculosis in the general population. A retrospective study was conducted on 250 clinical suspected tuberculosis patients who were HIV-negative and visited the Fourth People's Hospital of Foshan from January 2022 to December 2022. Among them, there were 135 cases of pulmonary tuberculosis, 34 cases of extrapulmonary tuberculosis, and 81 cases of non-tuberculosis. ⋯ The high-sensitivity urine LAM test holds promise for tuberculosis diagnosis in the general population. It demonstrates high-sensitivity, enabling the detection of sputum culture-negative pulmonary tuberculosis patients. Furthermore, when combined with existing methods, it can enhance the overall detection rate.

To investigate the correlation between central arterial pressure (CAP) parameters and the severity of atherosclerotic lesions in the coronary arteries, understand the value of CAP in assessing the risk of coronary heart disease (CHD), and provide a theoretical basis for the prevention and treatment of CHD. Between January 2021 and January 2022, 224 patients admitted to our hospital for complete coronary angiography (CAG) were included in this retrospective study. CAP parameters, including central systolic pressure (CSP), diastolic pressure (CDP), and pulse pressure (CPP), and Gensini scores were collected; the association between CAP parameters and the severity of coronary lesions was analyzed using the Pearson correlation coefficient (r) and multivariate regression analysis. ⋯ CSP, CDP, and CPP were significantly higher in the high Gensini score group than in the low Gensini score group for coronary vascular lesions; furthermore, CSP and CPP were significantly higher in the high Gensini score group than in the medium Gensini score group (P < .05). Pearson correlation analysis showed that CSP and CPP were positively and CDP was negatively correlated with the severity of coronary artery lesions in patients with CHD (P < .05). Logistic regression analysis showed that a history of diabetes, CSP, CDP, and CPP were independent risk factors for severe atherosclerotic lesions in the coronary arteries (P < .05). noninvasive CAP-related indices, such as CSP, CDP, and CPP, are independently correlated with and can be used to predict the severity of coronary lesions in patients with CHD, which may be beneficial for guiding clinical diagnosis and treatment.

Endothelial cell (EC) activation may increase systemic vascular permeability, causing extravascular lung water (EVLW) in sepsis with acute respiratory distress syndrome (ARDS). However, the correlation between thrombin and EVLW in sepsis and ARDS has not yet been addressed. Patients with sepsis and ARDS were prospectively enrolled between 2014 and 2016, and EVLW and serum thrombin levels on days 1 and 3 were measured and compared between surviving and non-surviving patients. ⋯ EVLW and thrombin levels were positively correlated (r2 = 0.71, P < .0001). In vitro, the morphology and junctions of HUVECs changed when the serum from patients with high EVLW was added. The intercellular distances among the control, high EVLW, and low EVLW groups were 5.25 ± 1.22, 21.33 ± 2.15, and 11.17 ± 1.64 µm, respectively (P < .05).

Intestinal stent implantation using a water injection device with carbon dioxide and transparent cap: A case report.
Preoperative endoscopic intestinal stent placement can relieve the symptoms of malignant bowel obstruction (MBO) pending investigations, staging, and surgery, but it is a technically challenging procedure. This paper presents a woman with MBO who successfully underwent intestinal stent implantation using a water injection device with carbon dioxide and a transparent cap. ⋯ Single-person intestinal stent implantation using a water injection device with carbon dioxide and a transparent cap can achieve endoscopic intestinal stent placement for MBO.

In-depth studies on the mechanisms of pathogenesis of sepsis and diagnostic biomarkers in the early stages may be the key to developing individualized and effective treatment strategies. This study aimed to identify sepsis-related hub genes and evaluate their diagnostic reliability. The gene expression profiles of GSE4607 and GSE131761 were obtained from the Gene Expression Omnibus. ⋯ The reliability and consistency of these 4 genes were externally validated. Single-sample gene set enrichment analysis and gene set variation analysis analyses indicated that the 4 hub genes were significantly correlated with the regulation of immunity and metabolism in sepsis. The identified FAM89A, FFAR3, G0S2, and FGF13 genes may help elucidate the molecular mechanisms underlying sepsis and drive the introduction of new biomarkers to advance diagnosis and treatment.
