Article Synopsis
  • This study examines how food passage routes after a specific stomach surgery, called proximal gastrectomy with double-tract reconstruction (PGDT), affect postoperative complications like esophageal reflux and malnutrition.
  • Patients were divided into two groups based on their food passage routes (remnant stomach influx - RSI vs. jejunal-loop - JL) and were analyzed for various health metrics and outcomes.
  • The findings revealed that the RSI group experienced less reflux and better retention of body metrics, suggesting that improving the food passage route can help reduce reflux and malnutrition after surgery.

Article Synopsis
  • The study aimed to categorize tumor-associated stroma (TAS) in triple-negative breast cancer (TNBC) to reflect its biological behavior.
  • Researchers analyzed 120 TNBC cases, classifying TAS into mature stroma (MS) and immature stroma (IS), finding that MS was more common and associated with higher tumor-infiltrating lymphocytes (TILs).
  • Results indicated that IS was linked to poorer progression-free and overall survival rates, highlighting the significance of TAS characteristics in TNBC prognosis and the need for further investigation.

Palindromic rheumatism (PR) is a type of cryptogenic paroxysmal arthritis. Several genes may be involved in PR pathogenesis; however, conducting comprehensive case-control genetic studies for PR poses challenges owing to its rarity as a disease. Moreover, case-control studies may overlook rare variants that occur infrequently but play a significant role in pathogenesis.

Background: No accurate prognostic tool is available for patients with cancer who spend their final days at home. In this study, we examined whether performance status (PS) and the palliative prognostic index (PPI), a well-known prognostic tool in palliative care units, could be used to predict prognosis in the home care setting at the time of intervention by home physicians.

Subjects And Methods: Using medical records, we conducted a retrospective analysis of 132 patients who were referred to the Home Clinic Naginoki for home care for terminal stages of carcinoma in situ.

We experienced a case of diffuse large B-cell lymphoma(DLBCL)that developed around the kidney about 1 year after surgery for sigmoid colon cancer. In this case, imaging findings suggestive of liver metastasis were also observed at the same time of diagnosis, therefore, diagnosis was difficult because the possibility of peritoneal dissemination could not be ruled out. The lesion was excised by surgery and a definitive diagnosis was obtained by tissue diagnosis, leading to appropriate treatment.

Background/aim: Recent studies have reported that the C-reactive protein (CRP) to albumin ratio (CAR) may be a useful prognostic biomarker in various types of cancer patients. However, the mechanism underlying this observation is unclear. The present study aimed to clarify why the CAR can predict post-esophagectomy prognosis, the relationship between pre- and postoperative CAR, and whether postoperative CAR can predict the prognosis of esophageal cancer patients.

Background: Perioperative factors are useful for predicting postoperative infectious complications (PIC) in gastric cancer. Specifically, postoperative inflammatory response indicators (PIRI), [C-reactive protein (CRP) level, body temperature (BT), and white blood cell (WBC) count], are widely used in clinical practice. We investigated predictive factors for PIC, including PIRI, to establish a simple and practical indicator of postoperative complications after gastrectomy.

Genome editing technology is widely used in the field of laboratory animal science for the production of genetic disease models and the analysis of gene function. One of the major technical problems in genome editing is the low efficiency of precise knock-in by homologous recombination compared to simple knockout via non-homologous end joining. Many studies have focused on this issue, and various solutions have been proposed; however, they have yet to be fully resolved.

Studying the non-human primate (NHP) brain is required for the translation of rodent research to humans, but remains a challenge for molecular, cellular, and circuit-level analyses in the NHP brain due to the lack of in vitro NHP brain system. Here, we report an in vitro NHP cerebral model using marmoset (Callithrix jacchus) embryonic stem cell-derived cerebral assembloids (CAs) that recapitulate inhibitory neuron migration and cortical network activity. Cortical organoids (COs) and ganglionic eminence organoids (GEOs) were induced from cjESCs and fused to generate CAs.

Background: Palindromic rheumatism (PR) is an infrequent form of periodic arthritis. Based on the similarity of the pathogenesis of PR to autoinflammatory syndromes, we previously found that the dominant-active splice variant of the inflammasome adaptor protein, apoptosis-associated speck-like protein containing a CARD (ASC), which lacks exon 2 (Δexon2), is expressed in Japanese patients with PR.

Objective: Elucidation of the mechanism of Δexon2 ASC production and the effect of IL-1β on splicing.

Article Synopsis
  • Laparoscopic surgery (LAP) is associated with fewer complications and improved outcomes for elderly patients undergoing colorectal cancer surgery, highlighting its minimal invasiveness compared to traditional methods.
  • In a study of 85 patients over 80 years old, LAP showed significantly lower rates of major complications and surgical site infections.
  • The research indicates that LAP not only reduces the risk of complications but also decreases non cancer-related mortality in very elderly patients, suggesting better overall survival rates.
