Laparoscopic Repair of Internal Hernia at the Pelvic Floor After Low Anterior Resection: A Case Report.

Internal hernia following colorectal surgery is an uncommon but serious complication. Most reported cases have involved hernias resulting from mesenteric defects after left-sided colon resection. We herein report a case of laparoscopic repair of an internal hernia at the pelvic floor following low anterior resection.

Finding the Right Hepatic Artery Branching from the Gastroduodenal Artery in a Patient Undergoing Gastrectomy: A Rare Case of an Anatomical Variant.

Numerous vascular anomalies of the hepatic artery have been reported. Protection of the hepatic arterial supply is important during gastrectomy. We herein report a case in which an anatomical variant of the hepatic artery was discovered in a patient undergoing laparoscopic distal gastrectomy with D1+ lymph node dissection for early gastric cancer.

Facultative endosymbiosis between cellulolytic protists and methanogenic archaea in the gut of the Formosan termite .

Anaerobic protists frequently harbour methanogenic archaea, which apparently contribute to the hosts' fermentative metabolism by consuming excess H. However, the ecological properties of endosymbiotic methanogens remain elusive in many cases. Here we investigated the ecology and genome of the endosymbiotic methanogen of the protists in the hindgut of the termite .

BMP Signaling Is a Prognostic Marker in Patients With Colorectal Cancer and Associates With Frailty.

Background/aim: Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-β superfamily of ligands and have been shown to promote or suppress colorectal cancer (CRC) growth. Developing treatments that target BMPs is challenging due to their multiple roles, including involvement in the inflammatory response and nutritional status. The present study evaluated the prognostic value of BMP-4, which is believed to be highly expressed in CRC, and its correlation with inflammatory and nutrition statuses in patients with CRC.

Switching disease-modifying therapies from sphingosine-1-phosphate receptor modulators to natalizumab or dimethyl fumarate restores immune responses after SARS-CoV-2 mRNA vaccination in patients with multiple sclerosis.

Objectives: This study aimed to evaluate whether switching disease-modifying therapies (DMTs) from sphingosine-1 phosphate (S1P) receptor modulators to either natalizumab (NTZ) or dimethyl fumarate (DMF) could restore the effectiveness of SARS-CoV-2 mRNA vaccination in patients with multiple sclerosis (MS).

Methods: This study included 9 controls and 33 patients with MS: 7 patients treated with DMF, 7 patients treated with NTZ, 9 patients treated with S1P receptor modulators, and 10 patients who had switched DMTs from S1P receptor modulators to DMF or NTZ by the second vaccine dose. The patients who had switched DMTs were classified into two groups, based on whether their lymphocyte counts were above or below 1000/μL at the time of vaccination.

The cachexia index is a prognostic factor for patients with recurrent pancreatic cancer.

Purpose: Cancer cachexia leads to poor outcomes, especially for patients with advanced stage disease. The cachexia index (CXI), a novel biomarker for cancer cachexia, has been identified as a prognostic indicator for several malignancies. The present study aimed to clarify the prognostic significance of the CXI for patients with recurrent pancreatic cancer.

Correlation between relative dose intensity of adjuvant S-1 chemotherapy and psoas muscle mass volume and survival after resection of pancreatic ductal adenocarcinoma: A retrospective study.

This study aimed to investigate the prognostic relationship between relative dose intensity (RDI) of adjuvant S-1 chemotherapy and psoas muscle mass volume (PMV) in patients with resected pancreatic ductal adenocarcinoma. We enrolled 105 patients with histologically confirmed pancreatic ductal adenocarcinoma who had undergone pancreatectomy. Adjuvant S-1 chemotherapy was administered to 72 (68.

Exosomal miR-493 suppresses MAD2L1 and induces chemoresistance to intraperitoneal paclitaxel therapy in gastric cancer patients with peritoneal metastasis.

Intraperitoneal (IP) chemotherapy with paclitaxel (PTX) for gastric cancer (GC) with peritoneal metastasis (PM) is considered a promising treatment approach, however, there are no useful biomarkers to predict the efficacy of IP therapy. We examined the association between intra-peritoneal exosomes, particularly exosomal micro-RNAs (exo-miRNAs), and IP-chemo sensitivity. MKN45 cells that were cultured with intra-peritoneal exosomes from patients who did not respond to IP therapy with PTX (IP group) exhibited resistance to PTX compared with exosomes from responding patients (IP group) (p = 0.

Using artificial intelligence to improve human performance: efficient retinal disease detection training with synthetic images.

Background: Artificial intelligence (AI) in medical imaging diagnostics has huge potential, but human judgement is still indispensable. We propose an AI-aided teaching method that leverages generative AI to train students on many images while preserving patient privacy.

Methods: A web-based course was designed using 600 synthetic ultra-widefield (UWF) retinal images to teach students to detect disease in these images.

Investigating the efficacy and safety of olanzapine prophylaxis for opioid-induced nausea and vomiting (JORTC-PAL20): a study protocol for an open-label, single-arm exploratory study.

Introduction: In opioid therapy for cancer pain, opioid-induced nausea and vomiting (OINV) occur in 20%-40% of patients during initial opioid treatment or increasing opioid doses. OINV result in failure to achieve pain relief due to poor opioid adherence. Therefore, antiemetics are used to prevent OINV, but their efficacy and safety in this context have not yet been fully elucidated.

In2Q2: A New Entry of 16-Membered Tetraazamacrocycle Concatenating Indole and Quinoline Units.

A new family of 16-membered macrocycles comprising two indole (In) and two quinoline (Q) units, coined In2Q2, was synthesized. Each unit is diagonally located and concatenated in a head-to-tail fashion, furnishing a non-flat saddle-shaped architecture with C symmetry. The synthetic protocol utilizing macrocyclic diamide as a pivotal precursor allowed us to access a series of In2Q2 derivatives bearing various substituents on the periphery.

Synthesis, activity, and their relationships of 2,4-diaminonicotinamide derivatives as EGFR inhibitors targeting C797S mutation.

The C797S mutation is one of the major factors behind resistance to the third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors. Herein, we describe the discovery of the 2,4-diaminonicotinamide derivative 5j, which shows potent inhibitory activity against EGFR del19/T790M/C797S and L858R/T790M/C797S. We also report the structure-activity relationship of the 2,4-diaminonicotinamide derivatives and the co-crystal structure of 5j and EGFR del19/T790M/C797S.

RGMa collapses the neuronal actin barrier against disease-implicated protein and exacerbates ALS.

Repulsive guidance molecule A (RGMa) was originally identified as a neuronal growth cone-collapsing factor. Previous reports have demonstrated the multifunctional roles of RGMa mediated by neogenin1. However, the pathogenic involvement of RGMa in amyotrophic lateral sclerosis (ALS) remains unclear.

Skeletal Muscle Mass Before Second-line Chemotherapy Correlates With Subsequent Prognosis and Rate of Late-line Chemotherapy in Patients With Unresectable Gastric Cancer.

Background/aim: Chemotherapy is the standard treatment for patients with unresectable gastric cancer (UGC); however, the survival outcomes are poor. This study investigated the predictive values of skeletal muscle mass (SMM) index (SMI) before second-line chemotherapy and the survival outcomes of patients with UGC.

Patients And Methods: A total of 79 patients diagnosed with UGC at our hospital who received at least second-line palliative chemotherapy were included.

Preoperative Osteopenia as Risk Factor for Death from Other Diseases After Gastrectomy in Elderly Patients.

Background/aim: Preoperative osteopenia, defined as low bone mineral density, is a prognostic factor in patients with digestive tract cancers, including gastric cancer (GC). However, the correlation between preoperative osteopenia and GC in elderly patients is unclear.

Patients And Methods: We enrolled 251 patients who had undergone curative surgery for histopathologically diagnosed gastric adenocarcinoma from January 2008 to December 2012.

Orbital fibrous capsule formation with abscess found 3 years after penetrating injury from a wooden chopstick.

Intraorbital wooden foreign bodies are sometimes difficult to diagnose because of nonspecific clinical manifestations and diversity of imaging characteristics. We herein report a case involving a 72-year-old woman with a history of trauma induced by a coated wooden chopstick 3 years prior. Two years after the incident, computed tomography (CT) scan revealed an intraorbital mass that was initially diagnosed as an intraorbital hemangioma.

Following car reduces motorcycles' size-arrival effect: A study using online experiments.

Many fatal motorcycle accidents occur because car drivers infringe on motorcycle riders' right-of-way. The size-arrival effect refers to observers' tendency to judge larger objects as arriving sooner than smaller objects when estimating an approaching object's arrival time, which is one cause of right-of-way motorcycle accidents. Previous research has focused on a single vehicle that approaches the driver.

Hepatectomy for massive hepatic necrosis after transcatheter arterial embolization hemostasis for hepatic hemorrhage following hepatic trauma: A case report.

Key Clinical Message: Although partial hepatic necrosis often occurs following endovascular treatment for bleeding associated with hepatic trauma, it is relatively rare that additional treatment is required. However, invasive procedures such as hepatic resection should sometimes be considered when infection occurs over massive hepatic necrosis.

Abstract: Although partial hepatic necrosis following endovascular treatment for bleeding associated with hepatic trauma is occasionally experienced, it is relatively rare for the necrotic area of the liver to require additional treatment.

Adult-onset botulism in a Japanese woman with prolonged spore excretion.

We report a case of an 80-year-old woman with botulism from 2020 in Osaka, Japan. The patient complained of dysarthria and dizziness. On the same day, the patient developed respiratory failure, and was intubated and placed on mechanical ventilation.

Preoperative low skeletal muscle volume can result in insufficient administration of S-1 adjuvant chemotherapy in older patients with stage II/III gastric cancer.

Background And Purpose: Older patients are more likely to encounter difficulties receiving chemotherapy, but the factors involved in the continuation of chemotherapy in these patients remain unclear. We investigated the importance of muscle mass as a factor involved in delivering a sufficient dose of postoperative S-1 adjuvant chemotherapy (ACT) to older patients with gastric cancer.

Methods: The subjects of this study were 79 patients aged ≥ 65 years with stage II/III gastric adenocarcinoma, who underwent curative gastrectomy and received S-1 ACT.

The function of REM and NREM sleep on memory distortion and consolidation.

During rapid eye movement (REM) sleep, newly consolidated memories can be distorted to adjust the existing memory base in memory integration. However, only a few studies have demonstrated the role of REM sleep in memory distortion. The present study aims to clarify the role of REM sleep in the facilitation of memory distortion, that is, hindsight bias, compared to non-rapid eye movement (NREM) sleep and wake states.
