Previous works have studied structural brain characteristics in first-episode psychosis (FEP), but few have focused on the relation between brain differences and illness trajectories. The aim of this study is to analyze gray and white matter changes in FEP patients and their relation with one-year clinical outcomes. A sample of 41 FEP patients and 41 healthy controls (HC), matched by age and educational level was scanned with a 3T MRI during the first month of illness onset. One year later, patients were assigned to two illness trajectories (schizophrenia and non-schizophrenia)...

Endoscopic mucosal resection and endoscopic submucosal dissection (ESD) are operative endoscopies that have been performed since a long time. Recently, an evolution of laparoscopy called transanal minimally invasive surgery began to be popularized, and it can be adopted in the face of difficult cases for endoscopic mucosal resection/ESD. In this video, a 36-year-old woman was submitted to transanal minimally invasive surgery resection, after unsuccessful ESD, for a 2-cm polyp located anteriorly in the anal canal, just beyond the pectineal line...

INTRODUCTION: There are growing concerns about the increase in rates of commonly used childbirth interventions. When indicated, childbirth interventions are crucial for preventing maternal and perinatal morbidity and mortality, but their routine use in healthy women and children leads to avoidable maternal and neonatal harm. Establishing ideal rates of interventions can be challenging. This study aims to describe the range of variations in the use of commonly used childbirth interventions in high-income countries around the world, and in outcomes in nulliparous and multiparous women...

In diagnosing peripheral pulmonary lesions (PPL), radial endobronchial ultrasound (R-EBUS) is emerging as a safer method in comparison to CT-guided biopsy. Despite the better safety profile, the yield of R-EBUS remains lower (73%) than CT-guided biopsy (90%) due to the smaller size of samples. We adopted a hybrid method by adding cryobiopsy via the R-EBUS Guide Sheath (GS) to produce larger, non-crushed samples to improve diagnostic capability and enhance molecular testing. We report six prospective patients who underwent this procedure in our institution...

Mechanical complications in peritoneal dialysis (PD), including intraluminal clogging of the PD catheter by fibrin, omentum, or blood clot, are major causes of outflow problems and, in rare cases, lead to technical failure. To visualize an intraluminal image of patients undergoing PD with ineffective ultrafiltration (UF), a SpyGlass fiber optic probe was inserted into the catheter, together with SpyBite biopsy forceps, should the removal of clogging materials be needed. Applying these transcatheter devices in 2 PD patients with unexplained UF failure led to the demonstration of omental plugging at the catheter tip in the first patient and demonstration of intraluminal blood clots in the second patient from whom clots were removal successfully...

The aim of this pilot test was to test a new self-locking resorbable implant for hilum occlusion during a video-assisted thoracoscopic lung lobectomy in a surviving pig model. Once the thoracic cavity was assessed and structures identified, the right middle lobe and its respective hilum were exposed. The implant was introduced with a semiclosed loop through a working channel and positioned around the pulmonary lobe. Occlusion was performed with a conventional Crile forceps and a laparoscopic Kelly forceps. Lobe section was done with laparoscopic Metzenbaum scissors and tissue removal through the dorsal access...

Shuai Li, Wipawee Winuthayanon
In mice, ejaculated semen is deposited in the uterus. After ejaculation, the semen changes consistency from gel-like to watery, a process called liquefaction. In this study, we show how to collect the post-ejaculated semen from the female reproductive tract in a mouse model. First, adult female mice in the estrus stage were housed in a male's cage overnight. The next morning, copulation was confirmed by the presence of copulatory plug at the vaginal opening. Female mice with copulatory plugs were euthanized, and each reproductive tract was collected as a whole (vagina, uterus, oviducts, ovaries), ensuring a closed system to contain the semen...

BACKGROUND: Pelvic organ prolapse is more common among parous (versus nulliparous) women and also more common after vaginal (versus cesarean) birth. However, very little is known about how childbirth affects the course and progression of pelvic organ prolapse across a woman's lifespan. OBJECTIVE: To investigate longitudinal, quantitative changes in pelvic organ support after childbirth, focusing on the impact of vaginal versus cesarean delivery. STUDY DESIGN: This was a prospective longitudinal cohort study in which parous women were recruited 5-10 years from first delivery and followed annually...
