Laparoscopically assisted aneurysmorrhaphy for iliac artery aneurysms following endovascular repair: reports of two cases.

Endovascular aneurysm repair (EVAR) is commonly utilized for iliac artery aneurysms (IAA), yet some cases necessitate additional intervention due to aneurysm re-expansion. We report two cases: a 68-year-old male with a left internal IAA (IIAA) and an 80-year-old female with both a left common iliac artery aneurysm (CIAA) and IIAA, who underwent aneurysmorrhaphy following initial EVAR. Both procedures were successful, significantly reducing aneurysm size without immediate complications.

Surgical explantation of the WATCHMAN device and right atrial thrombus: a case report.

A 74-year-old male with a history of cardioembolic stroke, chronic atrial fibrillation, and cerebral hemorrhage, who had undergone left atrial appendage closure using the WATCHMAN device 1 year prior, was diagnosed with a 25-mm intra-cardiac mass in the right atrium. The patient underwent the surgical removal of the right atrial mass and the explantation of the WATCHMAN device. The WATCHMAN device was explanted with an external incision at the base of the left atrial appendage, facilitating the removal of the device and the closure of the appendage through direct suturing.

Varicella outbreak at nursery school under routine immunization in Japan in 2017 and 2018 and vaccine effectiveness.

Background: In Japan, routine administration to one-year-old children of two-dose immunization for varicella was introduced in October 2014. Object The object of this study was to report outbreaks of varicella under routine immunization at a nursery school and in its surrounding area using data of surrounding areas from the (Nursery) School Absenteeism Surveillance System. Then, we measured the effectiveness of routine two-dose immunization for varicella to onset.

Susceptibility of nursery teachers to measles, rubella, varicella and mumps in Japan.

Background: A guideline published in 2018 by the Ministry of Health, Labour and Welfare stipulated confirmation of the vaccine history of nursery staff members.

Object: This study was conducted to elucidate nursery teachers' vaccine and infection histories for measles, mumps, rubella, and varicella through survey responses.

Method: After sending questionnaires through the mail to 5000 nursery teachers in November 2022, we received responses through December 2022.

Expanded quantum vortex liquid regimes in the electron nematic superconductors FeSeS and FeSeTe.

The quantum vortex liquid (QVL) is an intriguing state of type-II superconductors in which intense quantum fluctuations of the superconducting (SC) order parameter destroy the Abrikosov lattice even at very low temperatures. Such a state has only rarely been observed, however, and remains poorly understood. One of the key questions is the precise origin of such intense quantum fluctuations and the role of nearby non-SC phases or quantum critical points in amplifying these effects.
