Association between depression and incident dementia: Longitudinal findings from the share study.

BACKGROUND: The association between depression and dementia is still unclear, particularly regarding depression as a potential risk factor preceding dementia. Therefore, we aimed to verify if the presence of depression at baseline may increase the risk of dementia and cognitive impairment during 15 years of follow-up in the SHARE (Survey of Health, Aging and Retirement in Europe) study. METHODS: Depressive symptoms were defined using the EURO-D, with a score ≥4 indicative of depression. Incident dementia was ascertained using self-reported data and caregivers' information, cognitive impairment using objective cognitive tests. Cox regression analysis, adjusted for 10 baseline confounders, was run and hazard ratios (HRs), with their 95% confidence intervals, were estimated. RESULTS: In total 22,789 participants were included in the present analysis (mean age 64.2 years) and were predominantly female. The prevalence of depression at baseline was 24.9%. Over 15 years of follow-up, the onset of dementia occurred a median 2 years earlier in people with depression compared to those without. Depression at the baseline significantly increased the risk of dementia in the overall sample (HR = 1.74; 95% CI: 1.54-1.95) and the risk of cognitive impairment (HR = 1.15; 95% CI: 1.06-1.25). For dementia, the association was stronger in people less than 60 years (HR = 2.07; 95% CI: 1.42-3.02) than in participants aged ≥80 years (HR = 1.47; 95% CI: 1.14-1.91). A similar trend was observed for cognitive impairment. Among the single items of the EURO-D, loss of concentration was the strongest individual variable predicting the onset of dementia. CONCLUSIONS: Depression increased the risk of dementia and cognitive impairment, particularly in younger adults, whereas loss of concentration was the strongest individual predicting variable of dementia. These findings demonstrate the need for early detection of depression for preventing future cognitive worsening.

Dietary Patterns and Healthy or Unhealthy Aging.

BACKGROUND: The aging process is complex, comprising various contributing factors influencing late-life conditions and eventual occurrence of chronic diseases that generate high financial and human costs. These factors include genetic proneness, lifestyle conducted throughout life, environmental conditions, as well as dietary aspects, among others, all together modulating precise pathways linked to aging, making longevity a multidimensional event. SUMMARY: Compelling evidence support the concept that nutritional determinants have major impact on the risk of age-associated non-communicable diseases as well as mortality. Nutrition research has turned in recent years from considering isolated nutrients or foods to focusing on combinations of foods in dietary patterns in relation to their associations with health outcomes. This narrative review focuses attention on dietary patterns that may contribute to healthy or unhealthy aging and longevity with examples of traditional dietary patterns associated with healthy longevity and reviewing the association of healthy plant-based and unhealthy ultra-processed diets with frailty, a condition that may be considered a hallmark of unhealthy aging. KEY MESSAGE: There is currently accumulated evidence confirming the key role that dietary patterns mainly of plant origin may exert in modifying the risk of age-associated chronic diseases and healthy longevity. These types of dietary models, unlike those in which the use of ultra-processed food is frequent, are associated with a reduced risk of frailty and, consequently, with healthy aging.

The link between spirituality and longevity.

We are facing an inverted demographic pyramid with continuously growing aged populations around the world. However, the advances that prolong physical life not always contemplate its psychological and social dimensions. Longevity is a complex outcome influenced by a wide range of factors, including genetics, lifestyle choices, access to healthcare, socio-economic conditions, and other environmental factors. These factors have been generally considered in the compelling research that seeks the determinants of longevity, particularly those concerning personal lifestyle choices, socioeconomic conditions, and molecular mechanisms proposed to mediate these effects. Nonetheless, fundamental aspects that can affect health and well-being, such as spirituality and religiosity, have been somehow left aside despite numerous epidemiological studies showing that higher levels of spirituality/religiosity are associated with lower risk of mortality, even after adjusting for relevant confounders. Because spirituality/religiosity are dimensions of great value for patients, overlooking them can leave them with feelings of neglect and lack of connection with the health system and with the clinicians in charge of their care. Integrating spirituality and religiosity assessment and intervention programs into clinical care can help each person obtain better and complete well-being and also allowing clinicians to achieve the highest standards of health with holistic, person-centered care. The present narrative review aims to explore the available evidence of a relationship between spirituality/religiosity and longevity and discusses the possible mechanisms that can help explain such relationship.

Prevalence of sarcopenia in Africa: a systematic review and meta-analysis of observational studies.

BACKGROUND: Existing literature suggests that sarcopenia is a highly prevalent condition in older people. However, most studies to date reporting data on its prevalence have been mainly carried out in Western countries, while data on sarcopenia in Africa is scarce. With this systematic review and meta-analysis, we aimed to determine the prevalence of sarcopenia in African countries and to explore potential factors that could explain higher or lower prevalence of this condition in Africa. METHODS: Major databases for studies reporting data on sarcopenia in African countries were searched from inception to June 2023. We conducted a meta-analysis of the prevalence [and 95% confidence intervals (95% CIs)] of sarcopenia in Africa, applying a random effect model. Several sensitivity and meta-regression analyses were run. RESULTS: Among 147 articles initially screened, six articles (with seven cohorts) including a total of 10,656 participants were included. Mean age of participants was 66.9 years, and the majority were female (58.1%). The weighted prevalence of sarcopenia in the selected countries of Africa was 25.72% (95%CI: 18.90-32.55). This outcome was characterized by a high heterogeneity (I2 = 99%) and by publication bias. Among the factors investigated, sarcopenia was lower when assessed using only one anthropometric measure, or in South Africa. CONCLUSION: Sarcopenia is a prevalent condition in Africa and thus research regarding this topic is a public health priority. Future studies that cover African countries for which data are not available and using standardized criteria are needed.

Osteosarcopenia increases the risk of mortality: a systematic review and meta-analysis of prospective observational studies.

BACKGROUND & AIMS: Osteosarcopenia is a recently recognized geriatric syndrome. The association between osteosarcopenia and mortality risk is still largely underexplored. In this systematic review with meta-analysis of prospective cohort studies, we aimed to explore whether osteosarcopenia could be associated with a higher mortality risk. METHODS: Several databases were searched from the inception to 16th February 2024 for prospective cohort studies dealing with osteosarcopenia and mortality. We calculated the mortality risk in osteosarcopenia vs. controls using the most adjusted estimate available and summarized the data as risk ratios (RRs) with their 95% confidence intervals (CIs). A random-effect model was considered for all analyses. RESULTS: Among 231 studies initially considered, nine articles were included after exclusions for a total of 14,429 participants (mean age: 70 years; 64.5% females). The weighted prevalence of osteosarcopenia was 12.72%. Over a mean follow-up of 6.6 years and after adjusting for a mean of four covariates, osteosarcopenia was associated with approximately 53% increased risk of mortality (RR: 1.53; 95% CI: 1.28-1.78). After accounting for publication bias, the re-calculated RR was 1.48 (95%CI: 1.23-1.72). The quality of the studies was generally good, as determined by the Newcastle Ottawa Scale. CONCLUSIONS: Osteosarcopenia was significantly linked with an increased risk of mortality in older people, indicating the need to consider the presence of osteoporosis in patients with sarcopenia, and vice versa, since the combination of these two conditions typical of older people may lead to further complications, such as mortality.

Mild cognitive impairment predicts the onset of Sarcopenia: a longitudinal analysis from the English Longitudinal Study on Ageing.

BACKGROUND: Mild cognitive impairment (MCI) and sarcopenia are two common conditions in older people. It is not widely known if MCI could predict the onset of sarcopenia. Therefore, we aimed to investigate whether MCI could predict the occurrence of sarcopenia in a population of older adults. METHODS: In the ELSA (English Longitudinal Study on Ageing), MCI was defined as the absence of dementia, preserved functional capacity and low performance in three objective cognitive tests. Sarcopenia was diagnosed as having low handgrip strength and low skeletal muscle mass index during follow-up. The longitudinal association between MCI at the baseline and incident sarcopenia was assessed using a multivariable logistic regression model, reporting the data as adjusted odds ratios (OR) and 95% confidence intervals (95%CI). RESULTS: 3,106 participants (mean age of 63.1 years; 55.3% males) were included. People with MCI reported significantly lower mean handgrip strength values and Skeletal Mass Index (SMI), as well as a higher prevalence of obesity at baseline. At baseline, 729 people had MCI and during the ten years follow-up period, 12.1% of the initial population included had sarcopenia. On multivariate analysis, adjusted for 18 potential confounders, the presence of MCI (OR = 1.236; 95%CI: 1.090-1.596, p = 0.01) significantly predicted the onset of sarcopenia during follow-up. CONCLUSION: The presence of MCI at baseline was associated with a higher incidence of sarcopenia at ten-years follow-up, demonstrating a likely role of MCI as a predictor of the onset of sarcopenia in older people.

Telecoaching as a new training method for elderly people: a systematic review.

BACKGROUND: The numerous restrictive measures implemented during the recent COVID-19 pandemic have reduced the levels of physical activity (PA) carried out by elderly people and telecoaching (TC) could be a training method to maintain the recommended levels of PA. In fact, TC uses information and digital communications technologies, such as computers and mobile devices, to access training services remotely. Thus, this study aimed to systematically review the scientific literature to verify the application, efficacy, and safety of TC training programs. METHODS: PubMed, Scopus, and Web of Sciences databases were used for this review, and randomized controlled trials analyzing TC training programs for elderly people were included. Only articles written in English and published in the last decade were considered. RESULTS: 3 articles were included in the qualitative synthesis including 194 elderly people. The sample size ranged from 12 to 117 and the TC training program from 8 to 12 weeks. The TC training programs were applied to elderly people with metabolic diseases and respiratory diseases. TC training program was effective in elderly people with metabolic diseases while the benefits for respiratory diseases have yet to be clarified. CONCLUSION: TC seems to be a safe, effective, and injury-free training method, despite its limited application in elderly population. Future studies should better investigate this training method in elderly people in order to evaluate the effectiveness in a wider range of diseases.

Less favourable food consumption ratings in the Five-Color Nutri-Score are associated with incident frailty in older adults.

BACKGROUND: The Nutri-Score front-of-package labelling classifies food products according to their nutritional quality, so healthier food choices are easier when shopping. This study prospectively assesses the association of a diet rated according to the Nutri-Score system and incident frailty in community-dwelling older adults. METHODS: Cohort study with 1,875 individuals aged ≥60 recruited during 2008-2010 in Spain. At baseline, food consumption was assessed using a validated dietary history. Food was categorised into five Nutri-Score labels (A/green-best quality; B, C, D, E/red-worst quality) utilising an algorithm established in 2017 and currently in use. For each participant, a Five-Color Nutri-Score Dietary Index (5-CNS DI) in grams per day per kilogram was calculated. The 5-CNS DI sums up the grams per day of food consumed times their corresponding nutritional quality value (from A rated as 1 to E rated as 5) and divided by weight in kilograms. From baseline to December 2012, incident frailty was ascertained based on Fried's criteria. Statistical analyses were performed with logistic regression adjusted for main confounders. RESULTS: After a mean follow-up of 3.5 years, 136 cases of frailty were identified. The multivariable-adjusted odds ratios (95% confidence interval) of incident frailty across increasing quartiles of the 5-CNS DI were 1, 1.51 (0.86-2.68), 1.56 (0.82-2.98) and 2.32 (1.12-4.79); P-trend = 0.033. The risk of frailty increased by 28% (3-58%) with a 10-unit increment in this dietary index. Similar results were found with the Nutri-Score algorithm modified in 2022. CONCLUSIONS: consumption of a diet with less favourable Nutri-Score ratings doubles the risk of frailty among community-dwelling older adults.

Multimorbidity increases the risk of dementia: a 15 year follow-up of the SHARE study.

AIMS: the literature regarding the association between multimorbidity and dementia is still unclear. Therefore, we aimed to explore the potential association between multimorbidity at the baseline and the risk of future dementia in the SHARE (Survey of Health, Ageing and Retirement in Europe) study, a large European research survey, with a follow-up of 15 years. METHODS: in this longitudinal study, multimorbidity was defined as the presence of two or more chronic medical conditions, among 14 self-reported at the baseline evaluation. Incident dementia was ascertained using self-reported information. Cox regression analysis, adjusted for potential confounders, was run and hazard ratios (HRs), with their 95% confidence intervals (CIs), that were estimated in the whole sample and by 5 year groups. RESULTS: among 30,419 participants initially considered in wave 1, the 23,196 included participants had a mean age of 64.3 years. The prevalence of multimorbidity at baseline was 36.1%. Multimorbidity at baseline significantly increased the risk of dementia in the overall sample (HR = 1.14; 95% CI: 1.03-1.27) and in participants younger than 55 years (HR = 2.06; 95% CI: 1.12-3.79), in those between 60 and 65 years (HR = 1.66; 95% CI: 1.16-2.37) and in those between 65 and 70 years (HR = 1.54; 95% CI: 1.19-2.00). In the overall sample, high cholesterol levels, stroke, diabetes and osteoporosis increased the risk of dementia, particularly if present among participants between 60 and 70 years of age. CONCLUSIONS: multimorbidity significantly increases the risk of dementia, particularly in younger people, indicating the need for early detection of multimorbidity for preventing cognitive worsening.

Spirituality and heart failure: a systematic review.

OBJECTIVES: Heart failure (HF) is a frequent chronic disease with disturbing symptoms and complex treatments, associated with depression and lower quality of life. Some studies have shown that spirituality and religiosity may be relevant in these patients. We aimed to systematically review the medical literature on spirituality and religiosity in patients with HF. METHODS: Major databases for studies investigating the effect of spirituality and religiosity in people affected by HF were searched from inception until 26th April 2023. Studies with clear definition of spirituality or religiosity, validated diagnosis of HF, and reporting outcomes of interest (i.e., incidence of mortality, cardiovascular outcomes, and quality of life) were included. RESULTS: Among 810 non-duplicate records, we screened the full texts of 25 works. After excluding 18 studies, we included 7 studies (3 observational and 4 interventional) comprising 1234 HF patients followed up over a median of 3 months. Definitions of spirituality and religiosity were heterogeneous among the studies. The intervention studies showed improvements in quality-of-life parameters, some cardiovascular outcomes, or mortality, and the observational studies showed significant associations with these outcomes. CONCLUSIONS: Despite the extreme heterogeneity of the populations included, of the definition of spirituality and religiosity, and of the interventions in the few studies that included it, all the studies reported some positive associations with the outcomes examined. Spirituality/religiosity is an aspect not generally taken into account in the usual practice of medicine and can potentially contribute to improving the conditions of patients with HF, a chronic disease with unfavorable prognosis.

Use of bioelectrical impedance analysis in centenarians: a systematic review.

BACKGROUND: Centenarians often represent one of the best examples of aging successfully. However, the role of body composition or hydration status assessed with bioelectrical impedance analysis (BIA) is poorly explored in this population. Therefore, the aim of this systematic review was to better understand the use and the role of BIA for evaluating body composition and hydration status in centenarians. METHODS: We conducted a systematic review of the literature up to the 1st of May, 2022 for published articles providing data on BIA to evaluate body composition parameters or hydration status in centenarians. Data were summarized descriptively because a meta-analysis was not possible due to the scarcity of available studies. RESULTS: Among 2222 articles screened, four were eligible including 291 centenarians (mean age: 100.5 years) who were mainly women (88%). In one study, BIA overestimated fat-free mass and underestimated fat mass when compared to deuterium oxide dilution. Another study carried out in Italy including 14 centenarians found a significant correlation between BIA and fat-free mass evaluated using anthropometric tools. In one study, BIA showed a significant agreement with anthropometric measures of fat mass. In the same sample, sarcopenia and dehydration, evaluated with BIA, had a high prevalence. CONCLUSION: BIA may be used for assessing body composition in centenarians, but research is limited to a few studies suggesting the need of future research in this area.

Dynapenic abdominal obesity and incident multimorbidity: findings from the English longitudinal study on ageing.

BACKGROUND: Dynapenic abdominal obesity (DAO) (i.e., impairment in muscle strength and high waist circumference) is gaining interest, as it is associated with several important adverse health outcomes. However, the association between DAO and multimorbidity is largely unclear. Thus, the aim of the present study was to investigate the association between DAO at baseline and new onset multimorbidity over ten years of follow-up. METHODS: People participating in the English Longitudinal Study of Ageing were included. DAO was defined as waist circumference > 102 cm in men and > 88 cm in women, and a concomitant presence of dynapenia (handgrip strength defined as < 27 kg for men and < 16 kg for women). Multimorbidity was defined as having two or more chronic conditions. The association between DAO and incident multimorbidity was assessed using a multivariable logistic regression analysis, reporting the data as odds ratios (ORs) and their 95% confidence intervals (CIs). RESULTS: Overall, 3302 participants (mean age: 63.4 years, males: 50.3%) without multimorbidity at baseline were followed-up for ten years. After adjusting for several variables, compared to participants without dynapenia nor abdominal obesity, the presence of abdominal obesity (OR = 1.505; 95%CI: 1.272-1.780; p < 0.0001) and DAO (OR = 1.671; 95%CI: 1.201-2.325; p = 0.002) significantly increased the risk of multimorbidity. Compared to no dynapenia nor abdominal obesity, DAO was associated with significantly higher risk for arthritis and diabetes. CONCLUSIONS: DAO was significantly associated with a higher risk of incident multimorbidity, over 10 years of follow-up. The results of our study suggest that addressing DAO can potentially decrease risk for multimorbidity.

Risk of progression to diabetes and mortality in older people with prediabetes: The English longitudinal study on ageing.

AIMS: Prediabetes is used to identify people at increased risk for diabetes. However, the importance of prediabetes in older populations is still poorly explored. Therefore, we aimed to investigate the prevalence of prediabetes, based on either glycated haemoglobin (HbA1c) levels or fasting glucose (FG) levels, or both and the progression of prediabetes to diabetes or to mortality in older participants of the English Longitudinal Study on Ageing. MATERIALS AND METHODS: Prediabetes was categorized based on HbA1c levels (5.7%-6.4%) and/or FG levels (5.6-7.0 mmol/L). Information regarding mortality and incident diabetes were recorded during follow-up period of 10 years. RESULTS: In 2027 participants (mean age: 70.6 years, 55.2% females), the prevalence of prediabetes ranged between 5.9% and 31.1%. Over 8 years of follow-up, 189 participants (5.4% of the initial population) developed diabetes and 606 (17.4%) died. Among 1,403 people with HbA1c at the baseline <5.7%, 33 developed diabetes and 138 died; in contrast, among 479 participants with a diagnosis of prediabetes using a value of HbA1c between 5.7% and 6.4%, 62 developed diabetes and 56 died. Similarly, among 1,657 people with normal values of FG at baseline 60 had a diagnosis of diabetes during follow-up and 163 died, compared to 225 with FG between 5.6 mmol/L and 7.0 mmol/L in which 35 developed diabetes and 31 died. CONCLUSION: The prevalence of prediabetes in older adults is high, but the progression from prediabetes to diabetes is uncommon, whereas the regression to normoglycemia or the progression to death was more frequent.

Olive oil consumption is associated with lower frailty risk: a prospective cohort study of community-dwelling older adults.

BACKGROUND: There is no evidence on the specific beneficial association of the main types of olive oil consumption with frailty. OBJECTIVE: The aim was to assess the relationship between olive oil consumption and incident frailty in community-dwelling older adults. DESIGN: Prospective cohort. SETTING: Participants were recruited in 2008-10 and follow-up through 2013. SUBJECTS: In total, 1,896 older adults aged 60+. METHODS: At baseline, olive oil and other food consumption was collected using a validated dietary history. Incident frailty was defined as having at least three of the following five Fried-based criteria: low physical activity, fatigue, slow walking, muscle weakness and unintentional weight loss. Analyses were performed with logistic regression and adjusted for the major confounders. RESULTS: Over a mean follow-up of 3.5 years, 135 incident frailty cases were identified. The odds ratio (95% confidence interval) of frailty across sex-specific tertiles of total olive oil consumption (12.7, 20 and 30.8 g/day, respectively) were: 1 (ref.), 0.52 (0.32, 0.83) and 0.47 (0.29, 0.78), P trend 0.003. When differentiating by olive oil types, the results held for virgin but did not for common (refined) olive oil. CONCLUSION: The highest total olive oil consumption (~3 tablespoons), especially if virgin, was associated with half the risk of frailty as the lowest consumption (~1 tablespoon) among older adults. This study suggests that virgin olive oil should be the preferent culinary olive oil type for frailty prevention. If confirmed in other settings, small doses of virgin olive oil could be added as a simple geriatric nutritional advice on the prevention of frailty.

Suicide risk in caregivers of people with dementia: a systematic review and meta-analysis.

BACKGROUND: Interest in physical and mental health outcomes in caregivers of patients with dementia is increasing. However, there is limited data available on the prevalence of suicidal ideation, suicidal attempts, and suicide rates among caregivers of those with dementia. Therefore, we aimed to systematically review these outcomes to address this gap in the literature and thus provide information to inform future policy and intervention for the benefit of caregivers of dementia patients. METHODS: We searched several databases from inception to the 10th November 2021, for studies investigating suicidal ideation, suicidal attempts, and suicide rates of caregivers of patients with dementia. We report data regarding suicidal ideation as prevalence, with the 95% confidence intervals (CIs), applying a random-effect model; since less than three studies were available for suicide attempt and suicide, these data are reported descriptively. RESULTS: Among 194 articles, eight comprising 1,209 informal caregivers of people with dementia (mean age: 63.9 years, 74% females) were included. The prevalence of suicide ideation was 32.32% (95% CI: 16.01-48.64%; I2 = 98.5%, p < 0.0001). The prevalence of suicide ideation varied between studies from 4.69% to 77.78%. Two studies reported the rate of suicidal attempt in caregivers of patients with dementia, with the prevalence ranging from 5.9% to 16.1%. One study reported one in 17 caregivers of patients with dementia died by suicide. CONCLUSIONS: The prevalence of suicide ideation is high, affecting several caregivers of patients with dementia. These findings suggest intervention and/or policy are urgently needed to address suicidal behavior in this at-risk population.

Effect of COVID-19 quarantine on cognitive, functional and neuropsychiatric symptoms in patients with mild cognitive impairment and dementia.

BACKGROUND: During the last two years, COVID-19 affected older people with dementia or mild cognitive impairment (MCI), but conflicting and sparse results are still present. The objective of this study was to investigate the frequency and type of changes in functional, cognitive and behavioral and psychological symptoms of dementia (BPSD), and caregiver's stress during the period of quarantine in 2020 in patients affected by dementia/MCI living in Palermo, Sicily. METHODS: Outpatients affected by MCI/dementia were evaluated before and after COVID-19 quarantine. Functional status was investigated using basic and instrumental activities of daily living (ADL); cognitive performance with the mini-mental state examination; BPSD through the neuropsychiatric inventory (NPI). All scales were reported as pre/post-COVID-19 quarantine and a logistic regression analysis was performed for investigating the factors associated with worsening in NPI in patients and their caregivers. RESULTS: One hundred patients (mean age 77.1; females = 59%) were evaluated over a median of 10 months. In the sample as whole, a significant decline in functional and cognitive status was observed (p < 0.001 for both comparisons). The NPI significantly increased by 3.56 ± 8.96 points after the COVID-19 quarantine (p < 0.0001), while the caregivers' stress increased by 1.39 ± 3.46 points between the two evaluations (p < 0.0001). The decline was more evident in people with milder dementia. Higher values of instrumental ADL at baseline were associated with a significant lower worsening in NPI and caregiver's stress. CONCLUSIONS: COVID-19 quarantine negatively affected functional, cognitive, and neuropsychiatric symptoms in older people affected by dementia/MCI, highlighting the impact of COVID-19 quarantine for this population.

Dietary acrylamide and incident osteoporotic fractures: an 8-year prospective cohort study.

BACKGROUND: Acrylamide, a component of fried foods, has been associated with several negative health outcomes. However, the relationship between dietary acrylamide and osteoporotic fractures has been explored by a few cross-sectional studies. AIMS: To investigate if dietary acrylamide is associated with the onset of fractures in North American participants at high risk/having knee osteoarthritis (OA), over 8 years of follow-up. METHODS: A Cox's regression analysis, adjusted for baseline confounders was run and the data were reported as hazard ratios (HRs) and 95% confidence intervals (CIs). Dietary acrylamide intake was assessed at the baseline using a food frequency questionnaire and categorized in tertiles (T), whilst fractures' history was recorded using self-reported information. RESULTS: Altogether, 4,436 participants were included. Compared to participants with lower acrylamide intake (T1; < 3,313 µg), those with a higher acrylamide intake (T3; > 10,180 µg) reported a significantly higher risk of any fracture (HR = 1.37; 95% CI 1.12-1.68; p for trend = 0.009), forearm (HR = 1.73; 95% CI 1.09-2.77; p for trend = 0.04), spine (HR = 2.21; 95% CI 1.14-4.31; p for trend = 0.04), and hip fracture (HR = 4.09; 95% CI 1.29-12.96; p for trend = 0.046). CONCLUSIONS: Our study is the first to report that high dietary acrylamide may be associated with an increased risk of osteoporotic fractures.

The increased cortisol levels with preserved rhythmicity in aging and its relationship with dementia and metabolic syndrome.

BACKGROUND: In the aging process, the cumulative exposure to stress with increased cortisol levels is considered to be associated to the senescence itself and its related disorders. AIMS: To evaluate the role of cortisol in elderly subjects, with or without dementia, by the means of the AGICO study. METHODS: The AGICO study enrolled patients from ten Geriatric Units in Italy in 2012-2017 (Study Director Prof Paolo Falaschi, S. Andrea Hospital of Rome). Every subject received a comprehensive geriatric assessment (including the Mini-Mental State Examination, MMSE), the neurological examination (with a computed tomography scan or magnetic resonance imaging of the brain), the assessment of the metabolic syndrome (MetS), the evaluation of the cortisol activity by two consecutive urine collections (diurnal and nocturnal). RESULTS: The MMSE was inversely related to the standardized diurnal and nocturnal urinary cortisol levels (p < 0.025 and p < 0.01, respectively) and the age was positively related (p < 0.01 and p < 0.001, respectively). The ratio between the standardized diurnal and nocturnal urinary cortisol levels was 1.50 ± 1.2 (mean ± standard deviation) and it was not modified by the age or dementia. The standardized diurnal and nocturnal urinary cortisol levels were significantly higher in patients with dementia (MMSE < 24) (p < 0.01). In the analysis of the subgroups with MetS, the highest concentrations of diurnal and nocturnal cortisol were found in patients with both dementia and MetS (p < 0.025 and p < 0.01, respectively). DISCUSSION: The AGICO study showed that the stress response significantly and progressively increases with age. CONCLUSION: The cortisol increase in aging is related to the presence of both dementia and metabolic syndrome.

"A priori" Dietary Patterns and Cognitive Function in the SUN Project.

OBJECTIVES: To study and compare associations of 5 dietary patterns - Mediterranean dietary pattern (MDP), Dietary Approaches to Stop Hypertension (DASH), Mediterranean-DASH Intervention for Neurodegenerative delay (MIND), Alternative Healthy Eating Index (AHEI-2010), and a pro-vegetarian diet (PVD) - with cognitive function. PATIENTS AND METHODS: A subgroup of 806 participants from the "Seguimiento Universidad de Navarra"(SUN) cohort of university graduates, >55 years old, was interviewed with the validated Spanish Telephone Interview for Cognitive Status (STICS-m) at baseline and after 2 and 6 years. For recruitment to the SUN cohort, participants completed a validated food-frequency questionnaire to calculate dietary adherence scores. These scores were used as independent variables in linear regression models (a model for each dietary pattern) to assess their association with the 6-year change in STICS-m as the dependent variable. Linear mixed models were also fitted to compare trajectories of STICS-m scores. All models were adjusted for relevant confounding factors. RESULTS: Adjusted differences showed advantages in the 6-year change in STICS-m score of 0.25 (95% CI 0.04-0.45) for an increase of 1-SD (9 points) in the AHEI-2010 and of 0.27 (95% CI 0.05-0.48) for an increase of 1-SD (1.5 points) in the MIND diet. The MDP, DASH, and PVD scores yielded positive differences in their point estimates for an increase in 1-SD, but results were not statistically significant. The MIND diet appeared to modify changes in cognitive function over time. CONCLUSIONS: Our results showed a beneficial association between the MIND diet and cognitive function and suggested a benefit for the AHEI-2010 pattern. Results for the MDP, DASH, and PVD were inconclusive.

Association of the Dietary-Based Diabetes-Risk Score (DDS) with the risk of gestational diabetes mellitus in the Seguimiento Universidad de Navarra (SUN) project.

It is crucial to identify people at risk for type 2 diabetes mellitus (T2DM) and gestational diabetes mellitus (GDM) to implement preventive interventions in order to address these pandemics. A simple score exclusively based on dietary components, the Dietary-Based Diabetes-Risk Score (DDS) showed a strong inverse association with incident T2DM. The objective was to assess the association between DDS and the risk of GDM in a cohort of Spanish university graduates. The 'Seguimiento Universidad de Navarra' project is a prospective and dynamic cohort which included data of 3455 women who notified pregnancies between 1999 and 2012. The diagnosis of GDM is self-reported and further confirmed by physicians. A validated 136-item semi-quantitative FFQ was used to assess pre-gestational dietary habits. The development of the DDS was aimed to quantify the association between the adherence to this a priori dietary score and T2DM incidence. The score exclusively included dietary components (nine food groups with reported inverse associations with T2DM incidence and three food groups which reported direct associations with T2DM). Three categories of adherence to the DDS were assessed: low (11-24), intermediate (25-39) and high (40-60). The upper category showed an independent inverse association with the risk of incident GDM compared with the lowest category (multivariate-adjusted OR 0·48; 95 % CI 0·24, 0·99; P for linear trend: 0·01). Several sensitivity analyses supported the robustness of these results. These results reinforce the importance of pre-gestational dietary habits for reducing GDM and provide a brief tool to practically assess the relevant dietary habits in clinical practice.
