A patient who received a loop sigmoid colostomy was diagnosed with ulcerative colitis (pancolitis type) and treated with infliximab. Thereafter, he relapsed with intestinal inflammation only on the rectal side of the loop sigmoid colostomy and not on the oral side. Autologous fecal microbiota transplantation from the proximal intestine to the distal intestine was performed to treat the inflammation but was ineffective. He was treated with oral prednisolone and induced into remission. After analyzing fecal samples from the patient, we observed an alteration of the composition of the intestinal microbiota with intestinal inflammation, including a reduction of phylum Firmicutes in the inflamed distal intestine, whereas Firmicutes was conserved in the proximal non-inflamed intestine and recovered in the distal intestine after induction of remission. Thus, our results indicated that the inflammation was associated with an alteration of the intestinal microbiota.

Batch reactors are type of chemical reactors, where the reactants are loaded to process for a defined batch time and the products are removed after the polymerization reaction completion. Specialty chemicals and food processing industries widely use BRs due to their versatility and suitability for handling small- to medium-scale production, complex reactions, and varying reaction conditions. This article employs a CNN-LSTM-based nonlinear model predictive controller (NMPC) to effectively track the temperature profile of a BR.

Acute Large Bowel Obstruction Post Umbilical Hernia Repair Surgery: A Case Report.

Cureus

October 2024

Surgery, Bakersfield Memorial, Bakersfield, USA.

Article Synopsis
  • - Large bowel obstruction (LBO) is relatively rare, often caused by colorectal adenocarcinoma, and it typically presents with symptoms like abdominal pain, constipation, and nausea; a CT scan is crucial for diagnosis.
  • - A case study of a 41-year-old male showed severe LBO after a hernia repair, requiring emergency surgery due to findings of a blocked sigmoid colon and complications like pneumatosis.
  • - Diverticulitis, which is increasingly affecting younger individuals, can lead to bowel obstructions and serious complications; educating all patients about risk factors, including diet and surgical history, is important.

The COVID-19 pandemic has primarily been characterized by respiratory symptoms, but emerging evidence suggests multi-organ involvement, including the gastrointestinal tract. This case report aims to highlight colon perforation as a rare but significant complication in COVID-19 patients. We present two cases of male patients, aged 38 and 33, who were admitted with severe COVID-19 symptoms and required intubation and ventilator support.

Article Synopsis
  • Molecular dynamics (MD) simulations generate complex data that are challenging to analyze with traditional methods; however, combining this with deep learning allows for better understanding of structural changes in proteins, such as those caused by mutations.
  • The study specifically focuses on the SARS-CoV-2 spike protein's receptor-binding domain (RBD), using distance maps and deep convolutional neural networks to predict how point mutations affect the virus's infectivity and ability to evade immune responses.
  • Results showed promising predictive success regarding mutant types that enhance receptor affinity and reduce immunogenicity, with significant correlations found between simulation data and binding free energy changes, potentially aiding in identifying more infectious and immune-evasive strains of the virus.

Development of colonic stent simulator using three-dimensional printing technique: a simulator development study in Korea.

Clin Endosc

November 2024

Division of Gastroenterology, Department of Internal Medicine, Yeouido St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Korea.

Background/aims: Colonic stenting plays a vital role in the management of acute malignant colonic obstruction. The increasing use of self-expandable metal stents (SEMS) and the diverse challenges posed by colonic obstruction at various locations underscore the importance of effective training for colonic stent placement.

Methods: All the components of the simulator were manufactured using silicone molding techniques in conjunction with three-dimensional (3D) printing.
