Association between low values of mean arterial pressure and impaired cognitive performance in older patients with mild cognitive impairment: cross-sectional preliminary findings from the STRENGTH Project.

BACKGROUND: Uncontrolled blood pressure (BP) is a risk factor for Mild Cognitive Impairment (MCI) and dementia. AIMS: This study examined the relationship between BP and clinical/cognitive/neuropsychological aspects in MCI individuals. METHODS: MCI patients underwent clinical, functional, cognitive and metacognitive, as well as psychological assessments. Social network, lifestyle characteristics, and medication prescriptions were also evaluated. Each patient underwent BP measurements. RESULTS: Lower values of systolic BP (SBP), diastolic BP (DBP), and mean arterial pressure (MAP) were associated with poorer cognitive performance. Notably, MAP showed greater capability in detecting impairments in attention and visuospatial abilities compared to SBP and DBP. DISCUSSION: These findings support the notion that in older individuals with MCI excessively low BP values, particularly MAP, might represent a risk and suggest that cerebral hypoperfusion may play a key role. CONCLUSIONS: Routine assessment of MAP could aid clinicians in adjusting antihypertensive treatment and closely monitoring cognitive function in MCI patients.

Study of the effects of adapted Tango and multidimensional intervention in pREvention of dementia in agiNG: developing healTHy lifestyle programs (STRENGTH Project)-the experimental protocol of a prospective randomised controlled trial.

BACKGROUND: Dementia represents a key health issue for older adults, with negative consequences on psycho-social and functional status. Treatments that counteract cognitive deficits in mild cognitive impairment (MCI) are needed to prevent or delay it. AIM: To describe the experimental protocol of the STRENGTH Project. This study investigates a multimodal intervention in older adults with MCI to improve cognitive, functional, biochemical and psycho-social aspects. METHODS: The prospective randomised controlled trial will enrol 300 subjects with MCI (age ≥ 60 years). Participants will be randomly assigned to: (a) the experimental group, which will undergo sessions of adapted tango, music therapy, engagement in social activities, cognitive intervention and psycho-education for 6 months or (b) the control group, which will receive psycho-education and advice on healthy lifestyle for 6 months. All outcomes will be analysed before intervention (baseline), immediately after termination (follow-up 1), after 6 months (follow-up 2) and after 2 years (follow-up 3). DISCUSSION: We expect that the findings of this multidisciplinary study will be useful to optimize clinical and psycho-social interventions for improving cognitive and functional status of subjects with MCI. CONCLUSIONS: This project could have a meaningful impact on National Health Systems by providing clues on multidisciplinary management of older adults affected by cognitive decline to prevent dementia.

Subjective memory complaints in Italian elderly with mild cognitive impairment: implication of psychological status.

Subjective cognitive and memory complaints (SMC) are common in later life and are considered an indicator for progression to cognitive decline. The aim of the present study was to identify the relationship among SMC, neuropsychiatric symptoms and psychological aspects in elderly subjects with mild cognitive impairment (MCI) as well as to analyse the effect on SMC of a comprehensive cognitive training. Data from a sample of 94 patients enrolled in 'My Mind Project' (Grant No. 154/GR-2009-1584108) were collected. The study evidenced that depression was a significant predictor of SMC and that after the training, the number of subjects with SMC was significantly reduced in the experimental group in comparison to the control one. These results suggest that the participation in cognitive stimulation protocols may improve the perception of SMC in subjects with MCI.

Oxidative Stress in Elderly with Different Cognitive Status: My Mind Project.

BACKGROUND: Biomarkers of oxidative stress have been associated with cognitive status in humans and have been proposed to guide prognosis/treatment in Alzheimer's disease (AD) and mild cognitive impairment (MCI). OBJECTIVE: The aim of this study was to compare oxidative stress status in the plasma of mild-moderate AD, MCI, and healthy elderly with normal cognition (HE) undergoing a non-pharmacological intervention including multi-modal cognitive training ("My Mind Project"). METHODS: A prospective randomized trial involving 321 elderly people enrolled in Marche Region, Italy. Each subject was randomly assigned to an experimental (cognitive training) or to a control group. Cognitive performances and biomarkers have been analyzed before intervention (baseline), immediately after termination (follow-up 1), after 6 months (follow-up 2), and after 2 years (follow-up 3). The biological antioxidant potential (BAP) to Diacron reactive oxygen metabolites (d-ROM) ratio has been used as an indicator of oxidative stress status and as outcome variable. RESULTS: We have found no differences in the oxidative status among AD, MCI, and HE. Neither did we find a significant effect of the intervention within experimental groups. Gender was the sole factor with a strong significant effect on BAP/d-ROM. CONCLUSIONS: Based on these results, the utility of biomarkers of oxidative stress to guide prognosis/treatment in AD or MCI seems to be limited by lack of specificity, large interindividual variability, and gender bias.

[The emotional labor of nursing: critical incidents and coping strategies]. / Il lavoro emozionale dell'assistenza infermieristica: incidenti critici e strategie di coping.

INTRODUCTION: Despite the suggestion to adopt a balanced approach between detachment and involvement, the nurse-patient relationship is always embedded with emotional conflicts. AIMS: To collect data on how nurses manage the emotional support to patients. METHOD: The study adopted the theoretical perspective of the emotional work. Fifty-three nurses completed a questionnaire investigating everyday "emotional accidents." The data were analyzed considering the strategies employed to address and resolve them. RESULTS: All nurses exert an emotional work to try to outcome the dissonance between subjective emotions and emotional rules required by the professional role. There are three strategies: normalizing, regressive, transformative. Most of the emotional efforts are aimed at showing emotions in accordance with the role, even if they are dissonant with respect to the subjective feelings (surface acting). CONCLUSIONS: Nurses are expected to practice an "emotional neutrality", but their profession continually exposes them to a heavy emotional work that may be at the basis of emotional exhaustion and burnout. Strategies should be adopted to prevent stress and health damages.
