Both Gram-positive and Gram-negative bacteria release nanosized extracellular vesicles called membrane vesicles (MVs, 20-400 nm), which have great potential in various biomedical applications due to their abilities to deliver effector molecules and induce therapeutic responses. To fully utilize bacterial MVs for therapeutic purposes, regulated and enhanced production of MVs would be highly advantageous. In this study, we developed a universal method to enhance MV yields in both G+/G- bacteria through an autonomous controlled peptidoglycan hydrolase (PGase) expression system.

Article Synopsis
  • Mast cells and gut microbiota are pivotal in understanding Irritable Bowel Syndrome (IBS), but the exact interactions are still unclear.
  • Research using a mouse model showed that mice with IBS-associated microbiota had more mast cells, especially near neurons, compared to those with healthy microbiota.
  • The study found that certain receptors (TLR4 and H receptor) play significant roles in mast cell responses to IBS bacteria, impacting gut function and sensitivity.

The gut microbiota has been implicated in chronic pain disorders, including irritable bowel syndrome (IBS), yet specific pathophysiological mechanisms remain unclear. We showed that decreasing intake of fermentable carbohydrates improved abdominal pain in patients with IBS, and this was accompanied by changes in the gut microbiota and decreased urinary histamine concentrations. Here, we used germ-free mice colonized with fecal microbiota from patients with IBS to investigate the role of gut bacteria and the neuroactive mediator histamine in visceral hypersensitivity.

Objectives: Pregnancy and childbirth can lead to pelvic floor disorders, yet this topic is not routine in antenatal education. We aimed to determine the impact of a pregnancy workshop on women's postpartum pelvic floor health knowledge, performance of pelvic floor muscle exercises (PFME), symptoms, condition-specific quality of life, mode of delivery, and satisfaction.

Methods: This was a RCT.

Objectives: Pelvic floor disorders commonly affect women's quality of life. Their etiology is multifactorial, yet pregnancy and vaginal delivery (VD) are major inciting risk factors. Our objectives were to assess pelvic floor health information given by maternity providers to their pregnant patients, to create a pelvic floor health information workshop, and to determine its impact on women's preferences for mode of delivery.
