Although low-dose lactulose has shown a good theoretical foundation for the treatment of ulcerative colitis (UC) in previous studies, the exact effects and mechanism remain unclear. The rats were randomly distributed into 5 groups, i.e.

Rationale: Steven-Johnson syndrome (SJS) is characterized by severe illness, rapid progression, and high mortality rates, with the vast majority of cases induced by medications. Botulinum toxin, a neurotoxin produced by Clostridium botulinum, has not been reported in the literature as a causative agent of SJS.

Patient Concerns: A 56-year-old male patient, who underwent surgery for cerebral hemorrhage, developed widespread patchy annular papules following the injection of botulinum toxin into the masseter muscle.

Background & Aims: Hepatic encephalopathy (HE), one of the most serious prognostic factors for mortality in alcohol-related cirrhosis (ALD cirrhosis), is not recorded in Danish healthcare registries. However, treatment of HE with lactulose, the universal first-line treatment, can be identified through data on filled prescriptions. This study aimed to investigate if lactulose can be used as a surrogate marker of HE.

Objectives: This study focuses on analyzing the efficacy of lactulose oral solution combined with Macrogol 4000 Powder in the treatment of functional constipation (FC).

Methods: A total of 125 FC patients were selected, with 60 cases in a control group, who were treated with lactulose oral solution alone, and 65 cases in a research group, who were treated with lactulose oral solution combined with Macrogol 4000 Powder. The two groups were analyzed and compared in terms of efficacy, symptom recovery, Bristol Stool Form Scale (BSFS) and Wexner Constipation Scale (WCS) scores, adverse effects, serum indices, and Patient Assessment of Constipation Quality of Life (PAC-QOL).

Article Synopsis
  • Gastrointestinal (GI) barrier dysfunction is a critical early indicator of multiple complex diseases, but current testing methods for saccharide molecules used to assess this function are expensive and time-consuming.
  • A new one-component system utilizing a naphthyl-pyridine core and boronic acid receptor has been developed for the early detection of saccharide biomarkers like lactulose, which indicates GI barrier issues.
  • The innovative design incorporates a scalable 96-well format with gold nanoparticles and combines plasmonics and fluorescence for sensitive lactulose quantification, aiming to create an affordable and portable diagnostic tool for routine GI permeability testing.
