AI Article Synopsis
- Cryoablation, a technology used for various medical treatments, is being explored for ureteral endometriosis but lacks sufficient research.
- In a study using a balloon cryoprobe on pigs, cryoablation successfully created controlled areas of tissue necrosis with no immediate complications observed.
- The study showed that cryoablation is a feasible, safe, and effective method for targeting ureters, providing valuable insights for potential future clinical applications.
Article Abstract
Cryoablation, as a well-characterized technology, has multifarious clinical applications. But few are reported on ureteral endometriosis. Thus, we examined the feasibility and safety of cryotherapy with a novel balloon cryoprobe on ureter in a live porcine model. During the freezing and thawing cycle, temperature was recorded in different parts of the ureter in real-time. Two-minute cryoablation could induce necrosis within range in 1 cm diameter on serosa layer. The temperature respectively dropped to -136.5 °C, -96.1 °C and -17.5 °C at the cryotherapy center, 1 cm and 1.5 cm from center on serosal side. The ureters were harvested immediately, 2 weeks or 3 months after cryotherapy. No perforation, stricture, adhesions, or hydronephrosis was observed. Histopathologic representations of ureters after cryoablation indicated that full thickness necroses of ureters were seen in all samples. The results demonstrated ureteral cryoablation using a novel balloon probe was feasible, safe, and effective. These findings provided us reference before cryoablation could be applied in clinical practice in treating ureteral endometriosis.

Validation of an improved reference freeze-dried direct agglutination test for detecting leishmaniasis in the canine reservoir.

Proper identification and management of post-kala-azar dermal leishmaniasis (PKDL) and canine leishmaniasis (CanL) cases are among the prerequisites to the effective control of visceral leishmaniasis worldwide. Unlike PKDL, CanL still awaits effective improvement because of its cryptic nature, absence of parasites in lesions or lymph nodes and not complete sensitivity of some diagnostic tools in use. Because of the need for certain skills and equipment, both the liquid direct agglutination test and freeze-dried direct agglutination test (FD-DAT) versions are, in comparison with the indirect immunofluorescence antibody test (IFAT) or enzyme-linked immunosorbent assay (ELISA), practical and feasible diagnostic alternatives.

Aims: This study aims to verify the feasibility and safety of percutaneous coronary intervention (PCI) after a distal transradial approach (dTRA) with radial artery occlusion (RAO) recanalization.
Methods: Between July 2018 and January 2022, 30 patients underwent PCI following attempted RAO recanalization via dTRA. Among these cases, the target radial arteries could not be recanalized in five patients, necessitating alternative vascular access.

Purpose: To evaluate the safety, accuracy, and effectiveness of embryoscopy for the management of early abortion and to test the hypothesis that targeted embryo and chorionic villi sampling avoids maternal cell contamination (MCC) for genetic testing of products of conception (POC).
Methods: This ambispective study included 74 consecutive patients presenting with early abortion. Gestations between 5 and 9 weeks, obtained either spontaneously or through assisted reproductive technologies were included.

Objectives: Alcohol use disorder (AUD) is the most common substance use disorder in the United States. Despite availability of four FDA-approved medications, fewer than 10% of patients are prescribed medication. This study aimed to evaluate the impact and feasibility of emergency department (ED)-initiated oral naltrexone in patients with moderate to severe AUD.

Background: Domestic violence and abuse (DVA) is a violation of human rights that damages the health and well-being of-gay, bisexual and other men who have sex with men (gbMSM). Sexual health services provide a unique opportunity to assess for DVA and provide support. This study explores the feasibility and acceptability of Healthcare Responding to Men for Safety (HERMES), a pilot intervention aimed to improve the identification and referral of gbMSM experiencing DVA in a London NHS Trust.
