Queen garnet plum juice supplementation does not provide additional cognitive benefits over a group-based memory program in older adults with mild cognitive impairment: A randomized clinical trial Open
Research suggests a role for inflammation and oxidative stress in mild cognitive impairment (MCI) and its progression. Evidence suggests anthocyanin-rich foods may reduce inflammation and oxidative stress and improve cognition but benefits…

The Effect of Anthocyanins on Cognition: A Systematic Review and Meta-analysis of Randomized Clinical Trial Studies in Cognitively Impaired and Healthy Adults Open
Purpose of the Review Clinical trials suggest that dietary anthocyanins may enhance cognitive function. This systematic literature review and meta-analysis aimed to identify the effect of anthocyanin on cognition and mood in adults. Recent…

Assessing the effect of anthocyanins through diet and supplementation on cognitive function in older adults at risk for dementia: protocol for a randomised controlled trial Open
Introduction Promising evidence is emerging for the procognitive, anti-inflammatory and neuroprotective properties of dietary flavonoids, particularly anthocyanins that provide red, purple and blue plant pigments. Methods and analysis The …

Anthocyanins attenuate vascular and inflammatory responses to a high fat high energy meal challenge in overweight older adults: A cross-over, randomised, double-blind clinical trial Open
Postprandial metabolic imbalances are important indicators of later developing cardiovascular disease (CVD) (1) . This study investigated the effects of food anthocyanins on vascular and microvascular function, and CVD associated biomarker…

Habitual consumption of anthocyanin is associated with improvements in mood and cognitive performance in older people with memory complaints Open
The role of flavonoids on cognitive performance in older adults has been intensively studied, with the subclass of anthocyanins showing promising outcomes (1) . However, there is conflicting evidence in the case of individuals at high risk…

The effect of health literacy, depression, and pill burden on medication nonadherence in patients with kidney disease including kidney failure requiring dialysis Open
Aim To identify independent contributors to medication nonadherence in chronic kidney disease (CKD) and kidney failure (KF) patients on dialysis.Background Medication nonadherence is common in chronic diseases, including CKD and KF patient…

Exploring the necessary conditions for phonological interference in serial recall Open
This paper explores the impact of phonological overlap amongst items on short term memory recall performance by manipulating the type, number and syllabic position of shared phonemes between words in a serial recall task. Roodenrys et al […

The orthographic/phonological neighbourhood size effect and set size Open
A growing number of studies have shown that on serial recall tests, words with more orthographic/phonological neighbours are better recalled than otherwise comparable words with fewer neighbours, the so-called neighbourhood size effect. Gr…

Exploring the Agreement Between Self-Reported Medication Adherence and Pharmacy Refill-Based Measures in Patients with Kidney Disease Open
There is modest agreement between pharmacy refill-based measures and self-report MMAS measures when assessed categorically or quantitatively. Assessing adherence as a continuous variable should be considered to overcome the challenges asso…

Phonological similarity in the serial recall task hinders item recall, not just order Open
The phonological similarity effect in short‐term memory (STM) is the finding that serial recall of lists of similar sounding items is poorer than that of dissimilar sounding items. This is traditionally argued to be due to a detrimental ef…

Changes in measures of cognitive function in patients with end-stage kidney disease on dialysis and the effect of dialysis vintage: A longitudinal cohort study Open
Introduction Prevalence of cognitive impairment increases with worsening severity of chronic kidney disease (CKD) and majority of end-stage kidney disease (ESKD) patients on dialysis have cognitive impairment. Trends of cognitive function …

Comparison of health literacy profile of patients with end-stage kidney disease on dialysis versus non-dialysis chronic kidney disease and the influencing factors: a cross-sectional study Open
Objectives Lower health literacy (HL) is associated with poor outcomes in patients with kidney disease. Since HL matches the patient’s competencies with the complexities of the care package, the level of HL sufficient in earlier stages of …
