Objective: Semiquantitative lung ultrasound improves the timeliness of surfactant replacement, but its financial consequences are unknown. We aim to investigate if the ultrasound-guided surfactant administration influences the general costs of surfactant therapy for preterm neonates affected by respiratory distress syndrome.
Study Design: This is a pharmacoeconomic, retrospective, and before-and-after study investigating the impact of ultrasound-guided surfactant replacement (echography-guided Surfactant THERapy [ESTHER]) on pharmaceutical expenditure within the ESTHER initiative. Data extracted from the institutional official database hosted by the hospital administration for financial management were used for the analysis. We analyzed the number of surfactant administrations in neonates of gestational age ≤32 weeks, and the number of surfactant vials used from January 1 2014 to June 30, 2014 (i.e., during the period of standard surfactant administration policy) and from July 1, 2016 to December 31, 2018 (that is during ESTHER policy).
Results: ESTHER did not modify surfactant use, as proportion of treated neonates with RDS receiving at least one surfactant dose (Standard: 21.3% vs. ESTHER: 20.9%; = 0.876) or as proportion of used vials over the total number of vials opened for neonates of any gestational age (Standard: 37% vs. ESTHER: 35%; = 0.509).
Conclusion: Ultrasound-guided surfactant replacement using a semiquantitative lung ultrasound score in preterm infants with RDS does not change the global use of surfactant and the related expenditure.
Key Points: · ESTHER is able to increase the timeliness of surfactant replacement.. · The ultrasound-guided surfactant administration does not increase the cost of surfactant therapy.. · The ultrasound-guided surfactant administration does not change the global surfactant utilization..

Protocol-based treatment of spontaneous hemorrhage from varicose veins prevents recurrence of bleeding.
J Vasc Surg Venous Lymphat Disord

Department of Surgery, Central Michigan University, Saginaw, MI.
Article Synopsis
- Spontaneous hemorrhage from varicose veins can be a dangerous complication, and a two-step clinical protocol was developed to prevent immediate bleeding and ensure long-term results.* -
- The protocol involved a prospective registry of patients, where they received ultrasound assessments and immediate treatment through foam sclerotherapy, followed by planned endovenous ablation within eight weeks.* -
- Out of 59 patients treated, 95% had identifiable underlying issues, and while 52 received the immediate sclerotherapy, only 7 did not; results indicated no recurrent bleeding post-treatment, with a 7% rate of late hemorrhage in long-term follow-up.*
The establishment and severity assessment of ultrasound-guided prenatal bronchopulmonary dysplasia model in rat.

To study a new method for establishing animal models of prenatal bronchopulmonary dysplasia (BPD), we used lung ultrasound score (LUS) to semi-quantitatively assess the severity of lung lesions in model rats. Lipopolysaccharide (LPS) was injected into the right lung of the fetus of the rat under ultrasound-guided, and the right lung of the neonates were scanning for LUS. Specimens were collected for pathological scoring and detection of pulmonary surfactant-associated glycoprotein (SP)-C and vascular endothelial growth factor (VEGF) expression quantity.

Objective: To explore the potential effect of ultrasound-guided stellate ganglion block (SGB) on lung protection for patients undergoing one-lung ventilation (OLV).
Methods: A total of 123 patients undergoing elective one-lung ventilation surgery were selected as research subjects in this prospective study. These patients were randomly divided into the SGB group, control group and blank group on average.

Objective: To assess the influence of varying retention doses of ultrasound-guided polidocanol chemical ablation for benign cystic-solid thyroid nodules.
Methods: A retrospective study was conducted from December 2019 to January 2022, including 78 patients with benign cystic-solid thyroid nodules, of which 31 received polidocanol chemical ablation alone, 23 received polidocanol chemical plus thermal ablation, and 24 received open surgery. Patients who received polidocanol chemical ablation were assigned into groups based on the retention dose of polidocanol: 0 %, 10 %, 20 %, 30 %, and 50 %.
A Novel Tendon Injury Model, Induced by Collagenase Administration Combined with a Thermo-Responsive Hydrogel in Rats, Reproduces the Pathogenesis of Human Degenerative Tendinopathy.

Patellar tendinopathy is a common clinical problem, but its underlying pathophysiology remains poorly understood, primarily due to the absence of a representative experimental model. The most widely used method to generate such a model is collagenase injection, although this method possesses limitations. We developed an optimized rat model of patellar tendinopathy via the ultrasound-guided injection of collagenase mixed with a thermo-responsive Pluronic hydrogel into the patellar tendon of sixty male Wistar rats.
