Robot-Assisted Laparoscopic Resection With the Transanal Approach for Massive Rectal Gastrointestinal Stromal Tumor: A Case Report.

Rectal gastrointestinal stromal tumors (GISTs) are often asymptomatic and may be detected as giant tumors. This may require highly invasive surgery for radical resection. Here, we describe a 74-year-old man with a locally advanced non-metastatic GIST in the right anterolateral wall of the lower rectum.

Time-Space Network Hypertension in the Digital Era - Update From Jichi Medical University Hypertension Study.

Time-space network hypertension is a data science approach that connects diverse information related to hypertension within a time-space framework. This field of academic research aims to predict disease onset and direct effective, individualized, optimized treatments by integrating and analyzing the variability of multiple internal biological and external environmental signals as they relate to blood pressure variability across different time phases. By linking time series changes in blood pressure and biological distribution with multi-environmental and physiological information, enabled by advances in digital technology, the time-space network hypertension approach contributes to "digital hypertension" research.

Impact of robotic surgery on postoperative pancreatic fistula for high-risk pancreaticojejunostomy after pancreatoduodenectomy.

Background: The safety and feasibility of robotic pancreatoduodenectomy (RPD) in high-risk patients with postoperative pancreatic fistula (POPF) have rarely been investigated, although the rate of POPF is lower than in open pancreatoduodenectomy (OPD). This study aimed to examine the impact of robotic surgery on POPF in high-risk patients after pancreatoduodenectomy (PD).

Methods: This retrospective analysis included 204 patients who underwent RPD between January 2018 and June 2023.

Novel treatment strategy targeting interleukin-6 induced by cancer associated fibroblasts for peritoneal metastasis of gastric cancer.

Cancer-associated fibroblasts (CAFs) are a crucial component in the tumor microenvironment (TME) of peritoneal metastasis (PM), where they contribute to tumor progression and metastasis via secretion of interleukin-6 (IL-6). Here, we investigated the role of IL-6 in PM of gastric cancer (GC) and assessed whether anti-IL-6 receptor antibody (anti-IL-6R Ab) could inhibit PM of GC. We conducted immunohistochemical analysis of IL-6 and α-smooth muscle (α-SMA) expressions in clinical samples of GC and PM, and investigated the interactions between CAFs and GC cells in vitro.

Maternal Vitamin D Deficiency Is a Risk Factor for Infants' Epigenetic Gestational Age Acceleration at Birth in Japan: A Cohort Study.

Background/objectives: The DNA methylation of neonatal cord blood can be used to accurately estimate gestational age. This is known as epigenetic gestational age. The greater the difference between epigenetic and chronological gestational age, the greater the association with an inappropriate perinatal fetal environment and development.
