Life span is increasing in developed countries as Japan, and an aging society is becoming a problem. In fact, healthy lifespan is not extended, and it is desired to extend it by functional food. Cacao (Theobroma cacao) contains various active components and is considered a preventative agent against metabolic disease. In addition, it has long been thought that regular cacao intake extends a healthy lifespan. However, there is no direct evidence for this belief. The purpose of this study is to identify the cacao component that elongate the lifespan of D. melanogaster as a model organism and to elucidate its functional mechanism. The activation of sirtuins, a family of NAD+-dependent deacetylases, has been reported to extend the lifespans of various organisms. Heat shock factor 1 is known to be deacetylated by reaction with sirtuins, thereby inducing gene expression of various heat shock proteins by heat stress and effectively extending the lifespan of organisms. Fulvestrant supplier Therefore, we evaluated whether components in cacao activate sirtuins and extend the lifespan of D. melanogaster. In the process, we discovered the fatty acid tryptamide as a lifespan-elongating component of cacao. Therefore, we investigated whether the fatty acid tryptamide from cacao upregulates the genes of heat shock proteins. As a result, it was confirmed that the gene expression of multiple heat shock proteins was significantly increased. This suggests that fatty acid tryptamide may activate sirtuins, increase gene expression of heat shock proteins, and elongate the lifespan of D. melanogaster.
Mucosal incision-assisted biopsy (MIAB) is a valuable alternative to endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNAB) for sampling gastric subepithelial lesions (SELs). This study aimed to evaluate the potential risk of dissemination and impact on postoperative prognosis associated with MIAB, which has not yet been investigated.
Study 1 A prospective observational study was conducted to examine the presence or absence and growth rate of tumor cells in gastric juice before and after the procedure in patients with SELs who underwent MIAB (n = 25) or EUS-FNAB (n = 22) between September 2018 and August 2021. Study 2 A retrospective study was conducted to examine the impact of MIAB on postoperative prognosis in 107 patients with gastrointestinal stromal tumors diagnosed using MIAB (n = 39) or EUS-FNAB (n = 68) who underwent surgery between January 2001 and July 2020.
In study 1, although no tumor cells were observed in gastric juice in MIAB before the procedure, they were observed in 64% of patients after obtaining samples (P < 0.001). In contrast, no tumor cells were observed in the gastric juice in EUS-FNAB before and after the procedure. In study 2, there was no significant difference in 5-year disease-free survival between MIAB (100%) and EUS-FNAB (97.1%) (P = 0.27).
MIAB is safe, with little impact on postoperative prognosis, although the procedure releases some tumor cells after damaging the SEL's pseudocapsule.

Laparoscopic gastrectomy (LG) is performed widely, but whether LG is the optimal treatment for sarcopenic gastric cancer patients is unclear. This study aimed to determine whether LG is particularly beneficial for gastric cancer patients with sarcopenia.
We collected data concerning 604 consecutive patients who underwent gastrectomy for gastric cancer between January 2003 and December 2019. After adjustment using one-to-one propensity score matching, short-term and long-term outcomes were compared between LG and open gastrectomy (OG) groups among patients with sarcopenia and those without.
Among patients with and without sarcopenia, the LG group had a significantly longer operative time but less blood loss than the OG group. The two groups showed no significant differences regarding complications. Although 5-year overall and disease-specific survival were similar between LG and OG groups among patients with and without sarcopenia, LG was associated with greater 5-year non-gastric cancer-related survival than OG among patients with sarcopenia (88.3% vs. 78.1%, P = 0.048), but not those without.
LG for resectable gastric cancer was not inferior to OG regarding complications and outcomes in patients with or without sarcopenia. No difference in overall survival was evident between these approaches, but LG may lessen mortality from conditions unrelated to gastric cancer in sarcopenic patients.

Feeding tubes harbor microbial contaminants; studies to date have not explored differences between orogastric (OG) and nasogastric (NG) tube biofilms. We sought to extend a previous analysis by comparing bacterial colonization by location (OG v NG) and by evaluating clinical factors that may affect tube bacterial populations.
The pharyngeal segments of 41 infant feeding tubes (14 OG and 27 NG) from 41 infants were analyzed by next generation 16 S rRNA sequencing on the MiSeq platform.
At the phylum level, Proteobacteria had the highest relative abundance of both OG and NG tubes. At the genus/species level, nine taxa differed significantly between OG and NG tubes. Alpha and beta diversity analyses showed significant differences between OG and NG tubes with relatively little contribution from clinical factors.
The route of feeding tube insertion (oral vs nasal) had a greater impact on bacterial colonization than the assessed clinical factors.

Examine maternal and paternal ADHD and ASD symptoms in relation to very preterm (VPT) and full-term (FT) children's ADHD and ASD symptoms.
In this longitudinal study, maternal- and teacher-report of child ADHD and ASD symptoms were obtained for 119 children (VPT = 79, FT = 40) at age 5-years using the Conner's Rating Scale-Revised (CRS-R) and Social Responsiveness Scale-2 (SRS-2). A biological parent completed self- and observer-report CRS-R and SRS-2, and measures of mood/affect, stress, and social support to assess psychosocial distress. Data were analyzed using mixed-effect models adjusted for covariates.
Child ADHD symptoms were associated with VPT birth, maternal distress, and maternal ADHD symptoms (p ≤ 0.02), and paternal ADHD symptoms (p < 0.001). Regarding ASD, VPT birth and parental ASD symptoms were associated with child ASD symptoms (p ≤ 0.009). Parental symptoms and birth group had no interaction.
VPT birth and parental psychopathology represent independent risks for ADHD and ASD.

Critical congenital cardiac lesions rely on the patency of the DA to provide either systemic or pulmonary blood flow. A patent DA (PDA) that remains open can also have adverse consequences depending on the degree of systemic to-pulmonary shunting and volume of ductal steal. As such, the presence of a PDA may pose a challenge in the medical management and timing of surgical repair. In this perspective article, we provide an understanding of the role of the DA in the circulatory system in neonates with CHD and discuss traditional and emerging approaches to support the pulmonary and systemic circulations with manipulation of the DA.A patent ductus arteriosus (PDA) in infants born premature can present significant management challenges for neonatal providers. Quantifying a hemodynamically significant PDA (hsPDA) represents the first hurdle, however, identifying the best evidence-based approach amongst conservative, pharmacologic, and/or interventional management options has proven to be even more complicated. Within the conservative arm, furosemide to reduce pulmonary edema and improve lung function has spawned several discussions given the concerns for its upregulation of prostaglandin E2 in the kidneys and conflicting outcomes data. There remains no consensus regarding furosemide use in hsPDAs. In this perspective article, we summarize the approach to defining a hsPDA, review the current practice of furosemide use in the management of hsPDA, and suggest an approach to fluid management and diuresis to address the question is the routine use of furosemide in hsPDA merited in current practice?
Urethral injury is one of the most important complications in transanal total mesorectal excision (TaTME) in male patients with rectal cancer. The purpose of this study was to investigate holographic image-guided surgery in TaTME.
Polygon (stereolithography) files were created and exported from SYNAPSE VINCENT, and then uploaded into the Holoeyes MD system (Holoeyes Inc., Tokyo, Japan). After uploading the data, the three-dimensional image was automatically converted into a case-specific hologram. The hologram was then installed into the head mount display, HoloLens (Microsoft Corporation, Redmond, WA). The surgeons and assistants wore the HoloLens when they performed TaTME.
In a Wi-Fi-enabled operating room, each surgeon, wearing a HoloLens, shared the same hologram and succeeded in adjusting the hologram by making simple hand gestures from their respective angles. The hologram contributed to better comprehension of the positional relationships between the urethra and the surrounding pelvic organs during surgery. All surgeons were able to properly determine the dissection line.
This first experience suggests that intraoperative holograms contributed to reducing the risk of urethral injury and understanding transanal anatomy. Intraoperative holograms have the potential to become a new next-generation surgical support tool for use in spatial awareness and the sharing of information between surgeons.

Prodromal stages are well recognized in some neurological and immune-mediated diseases such as Parkinson disease, schizophrenia, type 1 diabetes mellitus and rheumatoid arthritis. Emerging evidence indicates that a prodromal stage exists in multiple sclerosis (MS), raising the possibility of intervention at this stage to delay or prevent the development of classical MS. However, much remains unclear about the prodromal stage of MS and considerable research is needed to fully characterize the prodrome and develop standardized criteria to reliably identify individuals with prodromal MS who are at high risk of progressing to a diagnosis of MS. In this Roadmap, we draw on work in other diseases to propose a disease framework for MS that incorporates the prodromal stage, and set out key steps and considerations needed in future research to fully characterize the MS prodrome, identify early disease markers and develop standardized criteria that will enable reliable identification of individuals with prodromal MS, thereby facilitating trials of interventions to slow or stop progression beyond the prodrome.
