RESUMO
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.

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: 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: 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.

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.

BACKGROUND: Coronavirus disease 19 (COVID-19) is a global outbreak. COVID-19 patients seem to have relevant coagulative abnormalities, even if they are not typical of disseminated intravascular coagulopathy (DIC) of the kind seen in septicaemia. Therefore, anticoagulant therapy with heparins is increasing in interest for a clinical approach to these patients, particularly if older. Studies comparing if prophylactic doses are more effective than therapeutic ones are still missing. METHODS: Data were collected in the Geriatric Section of the Dolo Hospital, ULSS 3 "Serenissima", Venice from 31st March to 01st May 2020. Heparins (calciparin, fondaparinux, enoxaparine) were divided into prophylactic or therapeutic doses. People previously treated with oral anticoagulants were removed. Vital status was assessed using administrative data. Cox's regression analysis, adjusted for potential confounders, was used for assessing the strength of the association between heparins and mortality. The data were reported as hazard ratio (HR) with 95% confidence intervals (CIs). RESULTS: 81 older people (mean age 84.1 years; females = 61.9%) were included. No significant differences in terms of demographic and clinical characteristics emerged between people treated with prophylactic or therapeutic doses, including age, gender, X-rays findings or severity of disease. Therapeutic doses were not associated to a better survival rate (HR 1.06; 95% CI 0.47-2.60; p = 0.89), even after adjusting for 15 confounders related to mortality (HR 0.89; 95% CI 0.30-2.71; p = 0.84). CONCLUSIONS: Our paper indicates that in older people affected by COVID-19 there is no justification for using therapeutic doses instead of prophylactic ones, having a similar impact on mortality risk.

Objective: While osteoarthritis (OA)-related pain increases the risk of physical inactivity, disability, and falls, less is known about whether pain increases the risk of frailty. We investigated if people with OA reporting pain are more likely to develop frailty than people with OA without pain. Design: Population-based prospective cohort study with a follow-up of 4.4 years. Setting: Community. Subjects: The subjects were 1,775 older men and women with osteoarthritis, enrolled in the Progetto Veneto Anziani. Methods: Pain was ascertained according to medical records, symptoms/signs, and use of analgesics. Participants were considered frail if they met three out of five criteria of Fried's Index. Results: Cross-sectional analysis at baseline demonstrated that after adjusting for potential confounders (age, gender, anthropometric and demographic data, comorbidities), people with OA and pain (n = 568) were significantly more likely to have frailty compared with those with OA without pain (n = 1,207; hand OA, OR = 1.86, 95% CI = 1.65-2.09; hip OA, OR = 1.62, 95% CI = 1.44-1.83; knee OA, OR = 1.42, 95% CI = 1.26-1.60; all p < 0.0001). Prospective analysis of 1,152 nonfrail subjects at baseline demonstrated that 19.9% developed incident frailty. A fully-adjusted logistic regression analysis demonstrated that lower limb OA-related pain was associated with an increased risk of developing frailty compared with people with OA and no pain. Conclusions: Pain related to OA might be an important factor influencing the relationship between OA and the development of frailty.

With the advance of technological progress and the increase in life expectancy, it is nowadays mandatory to define what is the therapeutic limit. Every day each physician must take therapeutic decisions on the basis of his scientific knowledge, but also of his own conscience and sense of limits. They can not avoid to consider the global risk of death, disability and morbidity in more advanced age, especially in the field of cardiology and cardiac surgery. In these subjects, both fit that frail, is necessary not only an evaluation for adequate risk assessment, but also a multidimensional assessment performed with advanced tools. The resilience of the subject, ability for which some patients considered out of therapy demonstrate the ability to adapt and overcome critical phases, must also be weighed. Where and what is the therapeutic limit should be evaluated individually with humility, competence and capacity for dialogue with other disciplines in a work team that respects the individual professionalism. In recent years, much has changed in the cardiology/cardiac surgery approach in old people. With the development of less or minimal invasive new techniques, there are no more insurmountable limits that can be connected only to the chronological age of the patients.

OBJECTIVE: Dehydroepiandrosterone sulfate (DHEAS) appears to have a protective effect against depression, but contrasting findings are available. Therefore, we investigated whether high serum DHEAS levels were associated with any protective effect on incident depression and incident severe depression in a representative group of elderly men and women. METHODS: In a population-based cohort longitudinal study in the general community, 789 older participants without depression and cognitive impairment at the baseline were included, among 3,099 screened subjects. Serum DHEAS levels were determined based on blood samples; incident depression and severe depression were diagnosed by means of the Geriatric Depression Scale (GDS) and confirmed by geriatricians skilled in psychogeriatric medicine. RESULTS: No baseline differences were found in GDS across age- and gender-specific tertiles of serum DHEAS. Over 4.4 years of follow-up, 137 new cases of depression were recorded. Of them, 35 among men and 64 in women were cases of incident severe depression. Cox's regression analysis, adjusted for potential confounders, revealed that higher DHEAS levels were associated with reduced risk of incident depression irrespective of gender (HR: 0.30; 95% CI: 0.09-0.96; Wald χ(2) = 4.09; df = 1; p = 0.04; women: HR: 0.31; 95% CI: 0.14-0.69; Wald χ(2) = 8.37; df = 1; p = 0.004) and of severe incident depression only in men (HR: 0.25; 95% CI: 0.06-0.99; Wald χ(2) = 4.05; df = 1; p = 0.04). CONCLUSION: Higher serum DHEAS levels were found to be significantly protective for the onset of depression irrespective of gender, whereas only in men was this association found also for incident severe depression.

Delirium is a common condition across different settings and populations. The interventions for preventing and managing this condition are still poorly known. The aim of this umbrella review is to synthesize and grade all preventative and therapeutic interventions for delirium. We searched five databases from database inception up to March 15th, 2023 and we included meta-analyses of randomized controlled trials (RCTs) to decrease the risk of/the severity of delirium. From 1959 records after deduplication, we included 59 systematic reviews with meta-analyses, providing 110 meta-analytic estimates across populations, interventions, outcomes, settings, and age groups (485 unique RCTs, 172,045 participants). In surgery setting, for preventing delirium, high GRADE evidence supported dexmedetomidine (RR=0.53; 95%CI: 0.46-0.67, k=13, N=3988) and comprehensive geriatric assessment (OR=0.46; 95%CI=0.32-0.67, k=3, N=496) in older adults, dexmedetomidine in adults (RR=0.33, 95%CI=0.24-0.45, k=7, N=1974), A2-adrenergic agonists after induction of anesthesia (OR= 0.28, 95%CI= 0.19-0.40, k=10, N=669) in children. High certainty evidence did not support melatonergic agents in older adults for delirium prevention. Moderate certainty supported the effect of dexmedetomidine in adults and children (k=4), various non-pharmacological interventions in adults and older people (k=4), second-generation antipsychotics in adults and mixed age groups (k=3), EEG-guided anesthesia in adults (k=2), mixed pharmacological interventions (k=1), five other specific pharmacological interventions in children (k=1 each). In conclusion, our work indicates that effective treatments to prevent delirium differ across populations, settings, and age groups. Results inform future guidelines to prevent or treat delirium, accounting for safety and costs of interventions. More research is needed in non-surgical settings.

BACKGROUND: The aim of this study was to determine the physiological effects of an high-intensity circuit training (HICT) on several cardiovascular disease risk factors in healthy, overweight middle-aged subjects, and to compare the effects of HICT to traditional endurance training (ET) and low-intensity circuit training (LICT). METHODS: Fifty-eight participants (ages 61 ± 3.3 yrs, BMI 29.8 ± 0.9) were randomly assigned to one of the three exercise treatment groups: HICT, LICT and ET. The three groups exercised three times per week, 50 min per session for 12 weeks. Baseline and after intervention anthropometric characteristics: body weight (BW), fat mass (FM); blood pressure: diastolic (DBP) and systolic (SBP), blood parameters; CHOL-t (total cholesterol), LDL-C (low density lipoprotein-cholesterol), HDL-C (high density lipoprotein-cholesterol), TG (triglycerides), ApoB and ratio ApoB/ApoA1 were measured. RESULTS: Compared to other groups, HICT showed significantly higher reductions in FM, DBP, CHOLt, LDL-C, TG, ApoB and significantly greater increases in high density HDL-C. LICT resulted in the greatest reduction in SBP. All groups showed a significant improvement of BW without any significant differences between groups. CONCLUSIONS: Our findings indicate that high-intensity circuit training is more effective in improving blood pressure, lipoproteins and triglycerides than endurance training alone or lower intensity circuit training.

Gout is the most common cause of inflammatory arthritis in men over 40 years old; it is a debilitating disease and, if untreated, can result in a chronic progressive disease, including tophaceous gout. In the elderly it represents a special issue, with notable clinical and therapeutic differences from the classical form with a systemic involvement. The burden of the disease increases particularly in the very old people, in whom arthritis, impaired gait and eyesight problems may enhance the related disability. Chronic gout moreover could aggravate heart and kidney disease and increase overall mortality and organ-related damage. Early diagnosis and appropriate treatment are important goals for the clinician that should to rely on the cooperation of specialists working together through the methodology of comprehensive geriatric assessment. The aim of the present review was to analyze chronic gout in old people in terms of epidemiology, pathophysiology, risk factors, clinical approach, and current treatment.

BACKGROUND: Pain and sarcopenia are common in older people. Cross-sectional studies have reported a significant association between these two conditions, but cohort studies exploring pain as a potential risk factor for sarcopenia are scarce. Given this background, the aim of the present work was to investigate the association between pain (and its severity) at baseline, and the incidence of sarcopenia over 10 years of follow-up in a large representative sample of the English older adult population. METHODS: Pain was diagnosed using self-reported information and categorized as mild to severe pain at four sites (low back, hip, knee, and feet). Incident sarcopenia was defined as having low handgrip strength and low skeletal muscle mass during the follow-up period. The association between pain at baseline and incident sarcopenia was assessed using an adjusted logistic regression analysis, and reported as odds ratios (ORs) with their 95% confidence intervals (CIs). RESULTS: The 4 102 participants without sarcopenia at baseline had a mean ± standard deviation age of 69.7 ± 7.2 years, and they were mainly male (55.6%). Pain was present in 35.3% of the sample. Over 10 years of follow-up, 13.9% of the participants developed sarcopenia. After adjusting for 12 potential confounders, people with pain reported a significantly higher risk of sarcopenia (OR = 1.46: 95% CI: 1.18-1.82). However, only severe pain was significantly associated with incident sarcopenia, without significant differences across the four sites assessed. CONCLUSIONS: The presence of pain, particularly severe pain, was associated with a significantly higher risk of incident sarcopenia.

Background: The prediction of the risk of falling remains a challenge in geriatric medicine and the identification of new potential reversible risk factors is a public health priority. In this study, we aim to investigate the association between DAO (dynapenic abdominal obesity) and incident falls in a large sample of people with knee OA (osteoarthritis) or at high risk for this condition, over 8 years of follow-up. Methods: DAO was defined using a waist circumference more than 102 cm in men and 88 cm in women and a concomitant presence of dynapenia, defined as a time over 15 s in the five times chair stands time. Falls, during follow-up, were recorded using self-reported information in the previous year. A logistic binary regression analysis was run, adjusted for potential confounders at the baseline, reporting the data as odds ratios (ORs) with their 95% confidence intervals (CIs). Results: Overall, 3,844 subjects were included, majority of whom had abdominal obesity. Across the 8 years of follow-up, 2,695 participants fell vs. 1,149 not reporting any fall. Taking those without DAO as reference, the presence of only dynapenia was not associated with risk of falls (OR = 1.18;95%CI: 0.73-1.91; p = 0.50), whilst the presence of abdominal obesity (OR = 1.30; 95%CI: 1.09-1.56; p = 0.004) and DAO (OR = 1.31; 95%CI:1.01-1.73; p = 0.04) were significantly associated with a higher risk of incident falls. Conclusion: DAO significantly increased risk of falls as well as the presence of abdominal obesity.
RESUMO
BACKGROUND AND AIMS: Congestive heart failure (CHF) is characterized by high levels of B-type natriuretic peptide (BNP), expanded total body water (TBW) and extracellular water (ECW). Bioelectrical impedance analysis (BIA) has demonstrated high diagnostic accuracy in CHF but no information is available for older patients. We hypothesized that, in the follow-up of patients with CHF, body fluid changes estimated by BIA are related to BNP variations rather than with body weight. The aim of this study was to evaluate the relationship between variations in body fluid compartments, body weight and BNP in hospitalized elderly patients with decompensated CHF. METHODS: 49 elderly patients admitted to the Geriatric Department for decompensated CHF were included in the study. On admission and at discharge, all patients underwent clinical and functional assessment and BNP dosage. TBW and ECW were also determined by the BIA method. RESULTS: At discharge, all patients showed reductions in TBW (ΔTBW -2.9 ± 3.0 liters), ECW (ΔECW 1.9 ± 2.1 liters) and BNP levels (ΔBNP -219.6 ± 458.1 pg/mL). Variations in TBW and ECW were correlated with BNP changes (r=0.65 and 0.62, respectively) rather than with body weight variations and BNP changes (r=0.51). CONCLUSIONS: The stronger relationship between fluid variations determined by BIA and BNP changes may make BIA a useful method in the follow-up of decompensated CHF elderly patients.

Corynebacterium macginleyi is a gram positive rod that causes especially ocular infections: since now only six elderly cases of extraocular infection are described. A 76 years old bedridden woman with a central venous catheter was hospitalized for 10 days of persistent fever. She was treated before with vancomicin and then with imipenem. The clinical conditions improved and the patient was discharged after two weeks of hospitalization. Among recognised risk factors for this infection the advanced age, indwelling devices and immunosuppression seem the most important. On the other hand, the antibiotics of choice are glycopeptides while the association of another antibiotic is recommended in our opinion only in severe clinical manifestation.

Animal models have indicated that influenza vaccination may prevent or delay the onset of dementia. However, the epidemiological evidence in human beings is still limited. Given this background, this systematic review and meta-analysis aimed to summarize the current state of the art of observational studies investigating the association between influenza vaccination and the risk of dementia. We searched Scopus and Pubmed/Medline until 24 September 2021 for studies investigating the risk of dementia by influenza vaccination status. After adjustment for potentially important confounding variables, data were reported as risk ratios (RRs) with 95% confidence intervals (CIs). Among 273 articles initially evaluated, five were included for a total of 292,157 older people free from dementia at baseline (mean age=75.5 ± 7.4 years; 46.8% females). All studies were of high quality. Over a mean follow-up of 9 years, influenza vaccination mitigated the risk of dementia (RR=0.97; 95%CI: 0.94-1.00; I2 =99%). This association held after adjustment for a mean of nine potential confounders (RR=0.71; 95%CI: 0.60-0.94; I2 =95.9%). In sensitivity analysis, removing one study from the adjusted analyses, the adjusted RR remained similar (RR= 0.67; 95%CI: 0.63-0.70), but the heterogeneity disappears (I2 =0%). In conclusion, influenza vaccination was associated with a significantly lower risk of dementia suggesting that the vaccination of older people against influenza may also aid in the prevention of dementia.

Frailty is an aging-related pathology, defined as a state of increased vulnerability to stressors, leading to a limited capacity to meet homeostatic demands. Extracellular microRNAs (miRNAs) were proposed as potential biomarkers of various disease conditions, including age-related pathologies. The primary objective of this study was to identify blood miRNAs that could serve as potential biomarkers and candidate mechanisms of frailty. Using the Fried index, we enrolled 22 robust and 19 frail subjects. Blood and urine samples were analysed for several biochemical parameters. We observed that sTNF-R was robustly upregulated in the frail group, indicating the presence of an inflammatory state. Further, by RNA-seq, we profiled 2654 mature miRNAs in the whole blood of the two groups. Expression levels of selected differentially expressed miRNAs were validated by qPCR, and target prediction analyses were performed for the dysregulated miRNAs. We identified 2 miRNAs able to significantly differentiate frail patients from robust subjects. Both miR-101-3p and miR-142-5p were found to be downregulated in the frail vs. robust group. Finally, using bioinformatics targets prediction tools, we explored the potential molecular mechanisms and cellular pathways regulated by the two miRNAs and potentially involved in frailty.

BACKGROUND: Hand osteoarthritis (OA) is common, but the efficacy/safety of treatment interventions aimed to improve health outcomes in this population are not well understood. Therefore, the aim of this study was to map and grade the effect of interventions for health outcomes in hand OA. METHODS: Umbrella review of systematic reviews with meta-analyses of randomized controlled trials (RCTs) using placebo/no intervention as control group. For outcomes with a p-value <0.05, the certainty of the evidence was evaluated using the grading of recommendations assessment, development and evaluation (GRADE) assessment. RESULTS: From 189 abstracts, 9 meta-analyses (24 outcomes) were included, with 8 reporting significant summary results. The use of splints was associated with reduced pain at medium term in thumb carpometacarpal OA (standardized mean difference [SMD]â¯= -0.70; 95% confidence intervals [95% CI]: -1.05 to -0.35; low certainty), reduced pain in long follow-up RCTs in symptomatic hand OA (SMDâ¯= -0.80; 95% CI: -1.16; -0.45; moderate certainty), and better function (SMDâ¯= 0.42; 95% CI: 0.08; 0.70; low certainty). The use of resistance training (SMDâ¯= -0.27; 95% CI: -0.47; -0.07) or physical exercise (SMDâ¯= -0.23; 95% CI: -0.42; -0.04) in improving hand pain and in improving finger joint stiffness (SMDâ¯= -0.36; 95%CI: -0.58; -0.15) was supported by a moderate certainty of evidence. The use of intra-articular hyaluronic acid in improving function (MDâ¯= 1.12; 95% CI: 0.61; 1.64; moderate certainty of evidence) was the only statistically significant pharmacological intervention. CONCLUSION: Only some non-pharmacological interventions are effective in improving health outcomes in hand OA and this evidence is supported by a moderate/low certainty, indicating the necessity of further interventional research.

Frailty is an aging related condition, which has been defined as a state of enhanced vulnerability to stressors, leading to a limited capacity to meet homeostatic demands. Cognitive impairment is also frequent in older people, often accompanying frailty. Age is the main independent risk factor for both frailty and cognitive impairment, and compelling evidence suggests that similar age-associated mechanisms could underlie both clinical conditions. Accordingly, it has been suggested that frailty and cognitive impairment share common pathways, and some authors proposed "cognitive frailty" as a single complex phenotype. Nevertheless, so far, no clear common underlying pathways have been discovered for both conditions. microRNAs (miRNAs) have emerged as key fine-tuning regulators in most physiological processes, as well as pathological conditions. Importantly, miRNAs have been proposed as both peripheral biomarkers and potential molecular factors involved in physiological and pathological aging. In this review, we discuss the evidence linking changes of selected miRNAs expression with frailty and cognitive impairment. Overall, miR-92a-5p and miR-532-5p, as well as other miRNAs implicated in pathological aging, should be investigated as potential biomarkers (and putative molecular effectors) of cognitive frailty.
