Background: Urinary tract infections (UTIs) are amongst the most common bacterial infections affecting women. Although antibiotics are the treatment of choice for UTI, cranberry derived products have been used for many years to prevent UTIs, with limited evidence as to their efficacy. Our objective is to assess the efficacy of a cranberry extract capsule standardized in A-type linkage proanthocyanidins (PACs) for the prevention of recurrent urinary tract infection.
Methods: We will perform a 1:1 randomized, controlled, double blind clinical trial in women aged 18 years or more who present ≥2 UTIs in 6 months or ≥ 3 UTIs in 12 months. One hundred and forty-eight women will be recruited and randomized in two groups to either receive an optimal dose of cranberry extract quantified and standardized in PACs (2 × 18.5 mg PACs per day) or a control dose (2 × 1 mg PACs per day). The primary outcome for the trial is the mean number of new symptomatic UTIs in women during a 6-month intervention period. Secondary outcomes are: (1) To evaluate the mean number of new symptomatic UTIs with pyuria as demonstrated by a positive leucocyte esterase test; (2) To detect the mean number of new symptomatic culture-confirmed UTIs; (3) To quantify urinary PACs metabolites in women who take a daily dose of 37 mg PACs per day compared to women who take a daily dose of 2 mg per day for 6 months; (4) To characterize women who present recurrent UTI based on known risk factors for recurrent UTI; (5) To describe the side effects of daily intake of cranberry extract containing 37 mg PACs compared to 2 mg PACs. This report provides comprehensive methodological data for this randomized controlled trial.
Discussion: The results of this trial will inform urologists, gynaecologists, family physicians and other healthcare professionals caring for healthy women with recurrent UTI, as to the benefits of daily use of an optimal dose of cranberry extract for the prevention of recurrent UTI.

Background: Diabetic foot ulcers present a formidable challenge due to colonization by biofilm-forming microorganisms, heightened oxidative stress, and continuous wound maceration caused by excessive exudation.
Methods: To address these issues, we developed a robust, stretchable, electro-conductive, self-healing, antioxidant, and antibiofilm hydrogel. This hydrogel was synthesized through the crosslinking of polyvinyl alcohol (PVA) and chitosan (CH) with boric acid.

This study systematically evaluated the color-enhancing effects of different co-pigmented molecules (amino acids, peptides, flavonoids and phenolic acids) with cranberry anthocyanins under different environmental conditions (light, dark, high temperature and ascorbic acid) and their potential mechanisms by various means, such as degradation kinetics, color stability, H NMR spectroscopy, and structural simulation analyses. The results showed that the introduction of co-pigments induced a strong color-enhancing effect and bathochromic shift, inhibited the degradation of anthocyanins (9.34 % ∼ 45.

A promising approach for managing root caries is the use of cross-linking agents to stabilize collagen. However, despite testing various natural and synthetic agents in vitro, their efficacy remains uncertain. The aim of this review was to examine which cross-linking agent performs better in reducing root caries lesion depth and the release of hydroxyproline, which is a marker of collagen degradation.
