Cyclic B-type proanthocyanidins in red wines and grapes have been discovered recently. However, proanthocyanidins of a different chemical structure (non-cyclic A-type proanthocyanidins) already known to be present in cranberries and wine possess an identical theoretical mass. As a matter of fact, the retention times and the MS/MS fragmentations found for the proposed novel cyclic B-type tetrameric proanthocyanidin in red wine and the known tetrameric proanthocyanidin in a cranberry extract are herein shown to be identical...

Chitosan interacts with proanthocyanidins through hydrogen-bonding, which allows encapsulation and development of stable nanoparticles via ionotropic gelation. Cranberry proanthocyanidins (PAC) are associated with the prevention of urinary tract infections and PAC inhibit invasion of gut epithelial cells by extra-intestinal pathogenic Escherichia coli (ExPEC). We determined the effect of cranberry proanthocyanidin-chitosan hybrid nanoparticles (PAC-CHTNp) on the ExPEC invasion of gut epithelial cells in vitro...

The use of food supplements containing herbs or other botanical ingredients (plant food supplements, PFS) is on the rise. In some cases, PFS can contain compounds that are toxic and may pose a health risk. To assess the potential health risks, information on the consumption of PFS is required, however, this was lacking for the Netherlands. In the current study, the consumption of PFS was investigated for several subgroups in the Dutch population, including children. Data from the Dutch National Food Consumption Surveys were used to get a first impression on the consumption of PFS...

Allergic asthma is a chronic inflammatory lung disease characterized by sensitization of the airways, and the development of immunoglobulin E antibodies, to benign antigens. The established pathophysiology of asthma includes recurrent lung epithelial inflammation, excessive mucus production, bronchial smooth muscle hyperreactivity, and chronic lung tissue remodeling, resulting in reversible airflow restriction. Immune cells, including eosinophils and the recently characterized type 2 innate lymphoid cells, infiltrate into the lung tissue as part of the inflammatory response in allergic asthma...

PURPOSE: Cranberries are a rich source of polyphenolic antioxidants. Purified sugars or artificial sweeteners are being added to cranberry-based food products to mask tartness. Refined sugar and artificial sweeteners intake modulate gut microbiota and result in metabolic complications. We evaluated effects of isomalto-oligosaccharides (IMOs; sweet tasting non-digestible oligosaccharides) with cranberry extract (CRX) on high fat diet (HFD)-induced metabolic alterations in mice. METHODS: Male Swiss albino mice were fed normal chow or HFD (58% fat kcal), and were administered either CRX (200 mg/kg) alone or in combination with IMOs (1 g/kg)...

OBJECTIVE: Previous studies have reported that polyphenol-rich extracts from various sources can prevent obesity and associated gastro-hepatic and metabolic disorders in diet-induced obese (DIO) mice. However, whether such extracts can reverse obesity-linked metabolic alterations remains unknown. In the present study, we aimed to investigate the potential of a polyphenol-rich extract from cranberry (CE) to reverse obesity and associated metabolic disorders in DIO-mice. METHODS: Mice were pre-fed either a Chow or a High Fat-High Sucrose (HFHS) diet for 13 weeks to induce obesity and then treated either with CE (200 mg/kg, Chow + CE, HFHS + CE) or vehicle (Chow, HFHS) for 8 additional weeks...

OBJECTIVE: The Affordable Care Act (ACA) established the Hospital-Acquired Condition (HAC) Reduction Program. The Centers for Medicare and Medicaid Services (CMS) established a total HAC scoring methodology to rank hospitals based upon their HAC performance. Hospitals that rank in the lowest quartile based on their HAC score are subject to a 1% reduction in their total Medicare reimbursements. In FY 2017, 769 hospitals incurred payment reductions totaling $430 million. This study analyzes how improvements in the rate of catheter-associated urinary tract infections (CAUTI), based on the implementation of a cranberry-treatment regimen, impact hospitals' HAC scores and likelihood of avoiding the Medicare-reimbursement penalty...
