Design, synthesis and evaluation of alpha lipoic acid derivatives to treat multiple sclerosis-associated central neuropathic pain.

Bioorg Med Chem 2022 Jun 20;69:116889. Epub 2022 Jun 20.

School of Chemistry and Molecular Biosciences, The University of Queensland, Brisbane, Queensland 4072, Australia. Electronic address:

Multiple sclerosis-associated central neuropathic pain (MS-CNP) is difficult to alleviate with clinically used pain-killers and so there is a large unmet medical need for novel treatments for alleviating MS-CNP. Although (R)-alpha lipoic acid (ALA) evoked significant pain relief efficacy in a mouse model of multiple sclerosis-associated central neuropathic pain (MS-CNP), this dietary supplement has poor oral bioavailability due to low gastric stability. Eight ester prodrugs of the R enantiomer of ALA [(R)-ALA] were designed encompassing a range of biocompatible hydrophobic and hydrophilic features and synthesized in an effort to identify a prodrug candidate that was stable at gastric and upper gastrointestinal tract (GIT) pH, and that could be released (hydrolyzed by esterases) in the blood to (R)-ALA immediately after absorption into the portal vein (i.

Which ICU patients need stress ulcer prophylaxis?

Cleve Clin J Med 2022 Jul 1;89(7):363-367. Epub 2022 Jul 1.

Department of Pulmonary Medicine and Department of Critical Care Medicine, Respiratory Institute, Cleveland Clinic, Cleveland, OH.

Critically ill patients are at an increased risk for developing stress ulcers of the mucosa of the upper gastrointestinal (GI) tract. Bleeding from stress ulcers was previously associated with a longer stay in the intensive care unit and an increased risk of death. Thus, most patients admitted to the intensive care unit receive stress ulcer prophylaxis. Read More

Protein-Losing Enteropathy Resolved by Eradication.

Eur J Case Rep Intern Med 2022 26;9(5):003312. Epub 2022 May 26.

Department of Internal Medicine, Hospital Garcia de Orta, Almada, Lisbon, Portugal.

Protein-losing enteropathy (PLGE) is an uncommon condition with a multifactorial origin, that is characterized by excessive loss of serum proteins into the gastrointestinal tract, resulting in hypoproteinaemia and oedema. The authors present the case of a 24-year-old man admitted to hospital for a 2-month history of lower extremity oedema and diarrhoea with a secretory pattern.

Paediatr Drugs 2022 Jun 30. Epub 2022 Jun 30.

Division of Pediatric Gastroenterology and Hepatology, Mayo Clinic, Rochester, MN, USA.

Objective: We aimed to assess the efficacy of intrapyloric botulinum toxin A injection (IPBTI) in children with and without gastroparesis and to perform a meta-analysis and review of the literature.

Chitosan-based oral colon-specific delivery systems for polyphenols: recent advances and emerging trends.

J Mater Chem B 2022 Jun 29. Epub 2022 Jun 29.

Nanotechnology and Biodelivery Laboratory, Department of Nutritional Sciences, University of Connecticut, Storrs, CT 06269, USA.

Oral colon-targeted delivery systems (OCDSs) have attracted great attention in the delivery of active compounds targeted to the colon for the treatment of colon and non-colon diseases with the advantages of enhanced efficacy and reduced side effects. Chitosan, the second-most abundant biopolymer next to cellulose, has great biocompatibility, is non-toxic, is sensitive to colonic flora and shows strong adhesion to colonic mucus, making it an ideal biomaterial candidate for the construction of OCDSs. Being rich in functional groups, the chitosan structure is easily modified, both physically and chemically, for the fabrication of delivery systems with diverse geometries, including nanoparticles, microspheres/microparticles, and hydrogels, that are resistant to the harsh environment of the upper gastrointestinal tract (GIT).

World J Surg Oncol 2022 Jun 28;20(1):217. Epub 2022 Jun 28.

State Key Laboratory of Esophageal Cancer Prevention & Treatment and Henan Key Laboratory for Esophageal Cancer Research of The First Affiliated Hospital, Zhengzhou University, Zhengzhou, 450052, Henan Province, China.

A study protocol of a randomized phase II trial of perioperative chemoimmunotherapy verses perioperative chemoimmunotherapy plus preoperative chemoradiation for locally advanced gastric (G) or gastroesophageal junction (GEJ) adenocarcinoma: the NeoRacing study.

BMC Cancer 2022 Jun 28;22(1):710. Epub 2022 Jun 28.

Department of Radiation Oncology, Fudan University Shanghai Cancer Center, 270 Dong'an Road, Shanghai, 200032, People's Republic of China.

Background: Perioperative chemotherapy (ChT) and preoperative chemoradiation (CRT) are both the standard treatments for locally advanced gastric cancer (LAGC). CRT can achieve a higher pathological complete regression (pCR) rate, but whether this higher pCR rate can be transformed into a long-term survival benefit remains inconclusive. Therefore, relevant studies are in progress. Read More

Contribution of the proximal and distal gastric phases to the breakdown of cooked starch-rich solid foods during static in vitro gastric digestion.

Food Res Int 2022 Jul 20;157:111270. Epub 2022 Apr 20.

Riddet Institute, Massey University, Private Bag 11222, Palmerston North 4442, New Zealand; Department of Biological and Agricultural Engineering, University of California, Davis, CA 95618, USA. Electronic address:

In vitro gastric digestion studies commonly focus on the acidic environment of the stomach (the distal phase), neglecting that the contact time between food and salivary amylase can be extended during bolus' temporary storage in the proximal stomach (the proximal phase). Consequently, the role of the proximal phase of gastric digestion on the breakdown of solid starch-based foods is not well understood. This study aimed to address this question using a static in vitro digestion approach. Read More

In vivo experimental validation of detection of gastric slow waves using a flexible multichannel electrogastrography sensor linear array.

Biomed Eng Online 2022 Jun 27;21(1):43. Epub 2022 Jun 27.

University of Auckland, Auckland, New Zealand.

Background: Cutaneous electrogastrography (EGG) is a non-invasive technique that detects gastric bioelectrical slow waves, which in part govern the motility of the stomach. Changes in gastric slow waves have been associated with a number of functional gastric disorders, but to date accurate detection from the body-surface has been limited due to the low signal-to-noise ratio. The main aim of this study was to develop a flexible active-electrode EGG array. Read More

Mucus-Penetrating Alginate-Chitosan Nanoparticles Loaded with Berberine Hydrochloride for Oral Delivery to the Inflammation Site of Ulcerative Colitis.

AAPS PharmSciTech 2022 Jun 27;23(6):179. Epub 2022 Jun 27.

Anhui Province Key Laboratory of Pharmaceutical Technology and Application, Key Laboratory of Xin'an Medicine Ministry of Education, Anhui Province Key Laboratory of Chinese Medicinal Formula, Anhui University of Chinese Medicine, Hefei, 230038, Anhui, China.

The rectal enemas of berberine hydrochloride (BH) have emerged as one of the most effective strategies in the clinical treatment of ulcerative colitis (UC). However, oral dosages of BH exhibit a poor anti-inflammatory effect of UC, which may attribute to premature absorption of BH by the upper gastrointestinal tract. Moreover, the thick colonic mucus layer obstructs the penetration of the drug, resulting in low bioavailability to the inflammatory site of the colon. Read More
