Challenges of Post-Venipuncture Jugular Venous Thrombosis in Patients with Secondary Hyperparathyroidism: A Case Report.

BACKGROUND Hyperparathyroidism is a common issue in patients on long-term hemodialysis, necessitating parathyroidectomy with deep venipuncture. These patients frequently exhibit a heightened incidence of vascular calcification, complicating deep venipuncture and increasing the risk of associated complications. Therefore, a crucial aspect of preoperative assessment in this population involves identifying vascular calcification, with a preference for ultrasound-guided intraplane puncture. Special care is required to prevent blood vessel injuries and postoperative complications such as deep vein thrombosis. CASE REPORT We present the case of a 66-year-old woman with secondary hyperparathyroidism who encountered challenges during an internal jugular vein puncture, leading to subsequent thrombosis. Initial attempts were hindered by calcification of the internal jugular vein's vascular wall, resulting in stratified damage to the vessel's wall. However, the ultrasound-guided in-plane puncture technique successfully allowed the insertion of a central venous catheter without further damage to the vascular wall. On the postoperative fourth day, thrombus formation was observed in the damaged vascular wall from the initial puncture. CONCLUSIONS The ultrasound-guided in-plane puncture technique is advantageous in overcoming the difficulties associated with puncturing through deep vein calcification in patients with secondary hyperparathyroidism. This technique also diminishes the likelihood of complications such as venous thrombosis.

Early monitoring-to-warning Internet of Things system for emerging infectious diseases via networking of light-triggered point-of-care testing devices.

Early monitoring and warning arrangements are effective ways to distinguish infectious agents and control the spread of epidemic diseases. Current testing technologies, which cannot achieve rapid detection in the field, have a risk of slowing down the response time to the disease. In addition, there is still no epidemic surveillance system, implementing prevention and control measures is slow and inefficient. Motivated by these clinical needs, a sample-to-answer genetic diagnosis platform based on light-controlled capillary modified with a photocleavable linker is first developed, which could perform nucleic acid separation and release by light irradiation in less than 30 seconds. Then, on site polymerase chain reaction was performed in a handheld closed-loop convective system. Test reports are available within 20 min. Because this method is portable, rapid, and easy to operate, it has great potential for point-of-care testing. Additionally, through multiple device networking, a real-time artificial intelligence monitoring system for pathogens was developed on a cloud server. Through data reception, analysis, and visualization, the system can send early warning signals for disease control and prevention. Thus, anti-epidemic measures can be implemented effectively, and deploying and running this system can improve the capabilities for the prevention and control of infectious diseases.

Circulating tumor DNA detection in peripheral blood in postoperative efficacy evaluation and recurrence risk prediction of lung cancer.

This study mainly explores the application in the evaluation of postoperative efficacy and recurrence risk prediction. In this study, 50 lung cancer patients treated with thoracic surgery were selected. Collect the peripheral blood of these patients before the operation, separate the blood sample from the plasma by high-speed centrifugal separation, extract the DNA in the plasma by the magnetic bead method, and then extract the ctDNA. A liquid-phase chip capture system is used to highly concentrate target DNA. We use the IlluminaHiseq platform to sort with high throughput and high depth. As an indicator of ctDNA detection and analysis, the AF value of gene mutation frequency is used for calibration. The sensitivity of CEA detection in peripheral blood of tumor patients (TP) is 30% (15/50), and the sensitivity of ctDNA detection is significantly higher than that of CEA detection. Research results show that the number.
