RESUMO
BACKGROUND: Modifiable risk factors for Parkinson's disease (PD) are poorly known. OBJECTIVES: The aim is to evaluate independent associations of different nutritional components, physical activity, and sedentary behavior and metabolic factors with the risk of PD. METHODS: In this population-based prospective cohort study using the data of the United Kingdom Biobank (from 2006-2010), 502,017 men and women who were free from PD (International Classification of Diseases 10th edition; "G20") at baseline were included. We implemented a Cox proportion hazard's model to evaluate the associations of different levels of physical activity, sitting time, sleep habits, diet quality, alcohol and coffee consumption, smoking, and body mass index with PD risk, adjusting for several confounding variables. RESULTS: During a median follow-up of 12.8 years, lifestyle factors including vigorous physical activity (hazard ration [HR] = 0.84; 95% confidence interval [CI], 0.75-0.94), low-to-moderate sitting time (HR = 0.89; 95% CI, 0.81-0.97), and high sleep quality (HR = 0.89; 95% CI, 0.80-0.99) were associated with a reduced risk of PD. Small amounts of coffee (HR = 0.88; 95% CI, 0.82-0.95), red meat (HR = 0.86; 95% CI, 0.76-0.97), and current smoking (HR = 0.65; 95% CI, 0.56-0.75) were also associated with a lower risk of PD, whereas alcohol intake (HR = 1.29; 95% CI, 1.06-1.56) with higher PD risk. Secondary analysis, including metabolic risk factors, confirmed these findings and highlighted the potential protective effect of plasma vitamin D and uric acid, but of low-density lipoprotein-cholesterol, triglycerides, and C-reactive protein as well. CONCLUSIONS: Vigorous physical activity, reduced sitting time, good sleep quality together with small coffee intake and vitamin D supplementation are potentially neuroprotective lifestyle interventions for the prevention of PD. © 2024 International Parkinson and Movement Disorder Society.

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.

INTRODUCTION: Recurrent falls are observed frequently among older people, and they are responsible for significant morbidity and mortality. The aim of the present study was to verify sensitivity, specificity and accuracy of World Guidelines for Falls Prevention and Management (WGFPM) falls risk stratification algorithm using data from the Osteoarthritis Initiative (OAI). METHODS: Participants aged between 40 and 80 years were stratified as 'low risk', 'intermediate risk' or 'high risk' as per WGFPM stratification. Data from the OAI cohort study were used, a multi-centre, longitudinal, observational study focusing primarily on knee osteoarthritis. The assessment of the outcome was carried out at baseline and during the follow-up visit at 24 months. Data about sensitivity, specificity and accuracy were reported. RESULTS: Totally, 4796 participants were initially included. Participants were aged a mean of 61.4 years (SD = 9.1) and were predominantly women (58.0%). The population was divided into three groups: low risk (n = 3266; 82%), intermediate risk (n = 25; 0.6%) and high risk (n = 690; 17.3%). WGFPM algorithm applied to OAI, excluding the intermediate-risk group, produced a sensitivity score of 33.7% and specificity of 89.9% for predicting one or more falls, with an accuracy of 72.4%. CONCLUSION: In our study, WGFPM risk assessment algorithm successfully distinguished older people at greater risk of falling using the opportunistic case finding method with a good specificity, but limited sensitivity, of WGFPM falls risk stratification algorithm.

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.

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.

Physical inactivity is an important, but potentially reversible risk factor for dementia and mild cognitive impairment (MCI). There is literature about physical activity and exercise for the prevention and management of dementia and MCI, but this had not been previously synthesized into specific guidelines about this topic. A recent guideline on physical activity and exercise in MCI and dementia was published, authored by several international societies, including lay representatives. In this commentary, we discuss the implications of this guidance for healthcare professionals, caregivers, and lay representatives involved in the care of people with MCI and dementia.The guidelines highlight the importance of physical activity and exercise in cognitively healthy persons and for dementia and MCI, at different stages of these conditions. For primary prevention of dementia, physical activity may be suggested in cognitively healthy persons. In people with MCI, mind-body interventions, such as yoga, have the greatest evidence, whilst the role of physical activity and exercise requires more evidence from high-quality randomized controlled trials. In people living with moderately severe dementia, exercise may be useful for maintaining physical and cognitive function. There are benefits of physical activity and exercise separate from their impact on cognitive outcomes. The guidelines also proposed some questions for future research. In conclusion, there is limited evidence on the beneficial role of physical activity and exercise in preserving cognitive functions in subjects with normal cognition, MCI or dementia. The guidelines support the promotion of physical activity based on the beneficial effects on almost all facets of health.

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.

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.

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.

BACKGROUND: Mild cognitive impairment (MCI) may evolve into dementia. Early recognition of possible evolution to Alzheimer's disease (AD) and dementia with Lewy Bodies (DLB) is of importance, but actual diagnostic criteria have some limitations. In this systematic review and meta-analysis, we aimed to find the most accurate markers that can discriminate patients with DLB versus AD, in MCI stage. METHODS: We searched several databases up to 17 August 2023 including studies comparing markers that may distinguish DLB-MCI from AD-MCI. We reported data regarding sensitivity, specificity, and the area under the curves (AUCs) with their 95% confidence intervals (CIs). RESULTS: Among 2219 articles initially screened, eight case-control studies and one cohort study were included for a total of 832 outpatients with MCI. The accuracy of cerebrospinal fluid (CSF) markers was the highest among the markers considered (AUC > 0.90 for the CSF markers), with the AUC of CSF Aß42/Aß40 of 0.94. The accuracy for clinical symptom scales was very good (AUC = 0.93), as evaluated in three studies. Although limited to one study, the accuracy of FDG-PET (cingulate island sign ratio) was very good (AUC = 0.95) in discriminating DLB from AD in MCI, while the accuracy of SPECT markers and EEG frequencies was variable. CONCLUSIONS: Few studies have assessed the accuracy of biomarkers and clinical tools to distinguish DLB from AD at the MCI stage. While results are promising for CSF markers, FDG-PET and clinical symptoms scales, more studies, particularly with a prospective design, are needed to evaluate their accuracy and clinical usefulness.

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.

Recommendations for the management of malnutrition among infants aged less than 6 months (<6 m) are based on limited evidence. This study aimed to describe the characteristics, treatment outcomes and outcome-associated factors among malnourished infants <6 m admitted at Médecins Sans Frontières (MSF) inpatient and ambulatory therapeutic feeding centres (ITFC and ATFC) in North-East Nigeria, 2019-2022. We conducted a descriptive analysis of the cohorts and logistic regression to measure the association between two selected outcomes-inpatient mortality and defaulting from the ambulatory programme-and possible factors associated. In total, 940 infants <6 m were admitted at ITFC. Most of them presented severe acute malnutrition and comorbidities, with diarrhoea being the most frequent. On discharge, 13.3% (n = 125) of infants were cured, 72.9% (n = 684) stabilized (referred to ATFC), 6.5% (n = 61) left against medical advice and 4.2% (n = 39) died. The median length of hospital stay was 10 days [IQR 7-14]. A hospital stay shorter than 10 days was significantly associated with inpatient mortality (aOR = 12.51, 95% confidence interval [CI] = 3.72-42.11, p ≤ 0.01). Among 561 infants followed up at the ATFC, only 2.8% reported comorbidities. On discharge, 80.9% (n = 429) were cured, 16.2% (n = 86) defaulted and 1.1% (n = 6) died. Male sex (aOR = 1.94, 95% CI = 1.15-3.27, p = 0.01), internally displaced status (aOR = 1.70, 95% CI = 1.05-2.79, p = 0.03) and <-3 WLZ (aOR = 1.95, 95% CI = 1.05-3.63, p = 0.03) were significantly associated with programme defaulting. Stabilization and recovery rates among malnourished infants <6 m in the studied project align with acceptable standards in this humanitarian setting. Notable defaulting rates from outpatient care should be further explored.
RESUMO
BACKGROUND: Clinical evidence suggests that pregnant women are more vulnerable to COVID-19, since they are at increased risk for disease progression and for obstetric complications, such as premature labor, miscarriage, preeclampsia, cesarean delivery, fetal growth restriction and perinatal death. Despite this evidence, pregnant women are often excluded from clinical trials, resulting in limited knowledge on COVID-19 management. The aim of this systematic review and meta-analysis is to provide better evidence on the efficacy and safety of available COVID-19 treatment in pregnant women. METHODS: Four authors searched major electronic databases from inception until 1 st November-2022 for controlled trials/observational studies, investigating outcomes after the administration of anti-SARS-CoV-2 treatments in pregnant women affected by COVID-19. The analyses investigated the cumulative incidence of delivery and maternal outcomes in pregnant women, comparing those taking active medication vs standard care. Risk ratios (RRs) with 95% confidence intervals were calculated. Statistical significance was assessed using the random effects model and inverse-variance method. This systematic review and meta-analysis was conducted in accordance with the updated 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The protocol has been registered in Prospero (number registration: CRD42023397445). RESULTS: From initially 937 non duplicate records, we assessed the full texts of 40 articles, finally including ten studies. In six studies, including 1627 patients, the use of casirivimab/imdevimab (CAS/IMD), remdesivir, and IFN-alpha 2b significantly decreased the need of cesarean section ((RR = 0.665; 95%CI: 0.491-0.899; p = 0.008; I 2 = 19.5%;) (Table 1, (Fig. 1). Treatments did not decrease the risk of preterm delivery, admission to neonatal ICU, or stillbirth/perinatal loss (p-values > 0.50 for all these outcomes) and did not prevent the progression of disease towards severe degrees (k = 8; 2,374 pregnant women; RR = 0.778; 95%CI: 0.550-1.099; p = 0.15; I 2 = 0%). Moreover, the use of medications during pregnancy did not modify the incidence of maternal death in two studies (Table 2). CONCLUSIONS: To our analysis, CAS/IMD, remdesivir, and IFN alpha 2b reduced the number of cesarean sections but demonstrated no effect on disease progression and other obstetric and COVID-19 related outcomes. The inability to evaluate the influence of viral load on illness development in pregnant women was attributed to lack of data. In our systematic review, no major side effects were reported. Though, it is essential for the medical community to focus more on clinical trials and less on episodic case reports and case series, with standardization of fetal and maternal outcomes.

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.

BACKGROUND: The use of short geriatric tools in the emergency department (ED) is increasing, but the literature is still conflicting. The aim of this study is to compare the precision and the accuracy of two short geriatric assessment tools to predict mortality in a cohort of older patients attending the ED. METHODS: A retrospective study was conducted including patients ≥ 65 years, attending the ED and transferred to a medical assessment unit from February to July 2022. Clinical Frailty Scale (CFS) and Brief Multidimensional Prognostic Index (Brief MPI) were administered. The association between Brief MPI and CFS and mortality was analysed via area under the curve (AUC) with its 95% confidence intervals (CIs), the C-statistics and a multivariate Cox's regression analysis, in the latter case reporting the data as hazard ratios (HRs) with their 95% CI. RESULTS: Among the 579 patients enrolled (mean age: 77 years), both Brief MPI and CFS showed a good accuracy in predicting mortality (AUC: 0.72; 95% CI: 0.61-0.83 for Brief MPI; 0.754; 95% CI: 0.65-0.83 for CFS). The discrimination of Brief MPI and CFS in predicting mortality was excellent, since the C-index of the Brief MPI was 0.85 and of CFS = 0.84. In the multivariate analysis, the risk for mortality was significantly increased for frailer subjects (HR 4.65; 95% CI: 1.45-15.00 for Brief MPI > 0.66; HR = 9.24; 95% CI: 1.16-76.90 for CFS > 6). CONCLUSIONS: Brief MPI and CFS showed a good accuracy/precision to predict mortality in older patients attending the ED. Considering that they are quick to perform, their introduction in ED clinical practice could be extremely helpful.

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.

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.

BACKGROUND: Only limited studies analyzed a possible relationship between frailty and infections. Our aim was to investigate the possible association between higher multidimensional prognostic index (MPI) values, a tool for evaluating multidimensional frailty, and the prevalence of infectious diseases, including antibiotics' cost and the prevalence of MDR (multidrug resistance) pathogens. METHODS: Older patients, affected by COVID-19, were enrolled in the hospital of Palermo over four months. RESULTS: 112 participants (mean age 77.6, 55.4% males) were included. After adjusting for potential confounders, frailer participants had a higher odds of any positivity to pathogens (prevalence: 61.5%, odds ratio = 15.56, p < 0.0001) compared to a prevalence of 8.6% in more robust, including MDR, and a higher costs in antibiotics. CONCLUSIONS: Higher MPI values, indicating frailer subjects, were associated with a higher prevalence of infections, particularly of MDR pathogens, and a consequent increase in antibiotics' cost.

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.

BACKGROUND: Knee osteoarthritis (OA) is a common condition, associated with a high rate of disability and poor quality of life. Despite the importance of such evidence in public health, no umbrella review (i.e., a review of other systematic reviews and meta-analyses) has systematically assessed evidence on association between knee OA and adverse health outcomes. AIMS: To map and grade all health outcomes associated with knee OA using an umbrella review approach. METHODS: The search was made across several databases up to 22 April 2022. We used an umbrella review of systematic reviews with meta-analyses of observational studies assessing the effect sizes, based on random effect summary, 95% prediction intervals, heterogeneity, small study effects, and excess significance bias. The evidence was then graded from convincing (class I) to weak (class IV). RESULTS: Among 3,847 studies initially considered, five meta-analyses were included for a total of five different outcomes. Three adverse outcomes were significantly associated with knee OA (i.e., cardiovascular mortality, falls, and subclinical atherosclerosis). The presence of knee OA was associated with a significantly higher risk of cardiovascular mortality (odds ratio, OR = 1.17; 95%CI, confidence intervals: 1.02-1.34), falls (RR = 1.34; 95%CI: 1.10-1.64), and conditions associated with subclinical atherosclerosis (OR = 1.43; 95%CI: 1.003-2.05). The certainty of each of this evidence was weak. CONCLUSIONS: Our umbrella review suggests that knee OA can be considered as putative risk factor for some medical conditions, including cardiovascular diseases and falls, however, it is important to note that the evidence is affected by potential biases.
