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...

American cranberry (Vaccinium macrocarpon) is native to Eastern North America. Recent studies have suggested that the A-type proanthocyanidins (PACs) in cranberries are effective in preventing urinary tract infection. To meet the growing interest in the cranberry market, an accurate, reliable, and simple method to determine PAC concentration is needed. In this study, a modified method using 4-dimethylaminocinnamaldehyde to quantify total PACs in cranberry products was validated. Cranberry juice extract powder, cranberry capsules containing juice extract, and cranberry juice concentrate were used as the samples in this study...

BACKGROUND: Neuropathic or neurogenic bladder describes a process of dysfunctional voiding as the result of injury in the brain, spinal cord or nerves innervating the bladder. People with neuropathic bladder, such as from spinal cord injury (SCI), are at significant risk of morbidity from urinary tract infections (UTI). Effective methods to prevent UTI in people with SCI have been sought for many years. Probiotics (micro-organisms that exert beneficial health effects in the host) have been recommended for bacterial interference of the urological tract to reduce colonisation by uropathogen and to manage the dual problems of infection and antibiotic resistance...

The antibacterial effect of cranberry juice and the organic acids therein on infection by uropathogenic Escherichia coli was studied in an experimental mouse model of urinary tract infection (UTI). Reduced bacterial counts were found in the bladder (P < 0.01) of mice drinking fresh cranberry juice. Commercially available cranberry juice cocktail also significantly reduced (P < 0.01) bacterial populations in the bladder, as did the hydrophilic fraction of cranberry juice (P < 0.05). Quinic, malic, shikimic, and citric acid, the preponderant organic acids in cranberry juice, were tested in combination and individually...

Urinary tract infections (UTIs) are the most common bacterial infections in women, and increase in incidence after the menopause. It is important to uncover underlying abnormalities or modifiable risk factors. Several risk factors for recurrent UTIs have been identified, including the frequency of sexual intercourse, spermicide use and abnormal pelvic anatomy. In postmenopausal women UTIs often accompany the symptoms and signs of the genitourinary syndrome of menopause (GSM). Antimicrobial prophylaxis has been demonstrated to be effective in reducing the risk of recurrent UTIs in women, but this may lead to drug resistance of both the causative microorganisms and the indigenous flora...

BACKGROUND: Urinary tract infection (UTI) is a common complication among patients with hip fractures. Receiving an indwelling urinary catheter is a risk factor for developing UTIs. Treatment of symptomatic UTIs with antibiotics is expensive and can result in the development of antimicrobial resistance. Cranberries are thought to prevent UTI. There is no previous research on this potential effect in patients with hip fracture who receive urinary catheters. AIM: The aim of this study is to investigate whether intake of cranberry juice concentrate pre-operatively decreases the incidence of postoperative UTIs in hip fracture patients that received a urinary catheter...

Cranberry is reported to have health benefits including prevention of urinary tract infections and other chronic diseases, due to the high content of polyphenols including flavonols and flavan-3-ols. The aim of this study was to determine the clearance of flavonol glycosides and flavan-3-ols and/or their metabolites in human urine. Ten healthy women volunteers ingested 240 ml cranberry juice containing flavonol glycosides. Urine samples were collected at 0, 90, 225 and 360 minutes post-ingestion. While flavan-3-ols were not detected, five flavonol glycosides common in cranberry were identified...

Drinking of cranberry fruit juice and application of commercial preparations containing the cranberry extracts are recommended in the prevention and treatment of urinary tract infections (UTIs), especially in women with recurrent UTIs. Many studies focus on the activity of cranberries against uropathogenic Escherichia coli (E. coli) strains. However, the knowledge of the cranberry effect on Gram-positive Enterococcus faecalis (E. faecalis) is limited. Therefore, the aim of our study was to establish the activity of commercial concentrated cranberry extract on the growth, virulence factors and biofilm formation of E...

Cytochrome P450 inhibition through fruit supplement interactions often results in increased serum levels of calcineurin inhibitors, including tacrolimus. Cranberry extract is a supplement often used for the prevention of recurrent urinary tract infections (UTIs), which are common in renal allograft recipients. To our knowledge, a decrease in serum levels of tacrolimus as a result of cranberry extract interaction is unreported. A 40-year-old renal transplant patient taking cranberry extract capsules for her recurrent cystitis presented asymptomatically with low serum levels of tacrolimus...

Proteus mirabilis is a major cause of catheter-associated urinary tract infection (CAUTI), emphasizing that novel strategies for targeting this bacterium are needed. Potential targets are P. mirabilis surface-associated swarming motility and the propensity of these bacteria to form biofilms that may lead to catheter blockage. We previously showed that the addition of cranberry powder (CP) to lysogeny broth (LB) medium resulted in impaired P. mirabilis swarming motility over short time periods (up to 16 h). Herein, we significantly expanded on those findings by exploring (i) the effects of cranberry derivatives on biofilm formation of P...

PURPOSE: Urinary tract infections (UTIs) are widespread and affect a large portion of the human population. Cranberry juices and extracts have been used for UTI prevention due to their content of bioactive proanthocyanidins (PACs), particularly of the A type (PAC-A). Controversial clinical results obtained with cranberry are often due to a lack of precise determination and authentication of the PAC-A content. This study used Oximacro (Biosfered S.r.l., Turin, Italy), a cranberry extract with a high content of PAC-A, to prevent UTIs in female and male volunteers...
