Does presbygeusia really exist? An updated narrative review.

This review critically assessed the existence of presbygeusia, i.e., the impairment in taste perception occurring in the elderly, as a natural part of the aging process and its potential clinical implications. Several factors might contribute to age-related taste alterations (TAs), including structural changes in taste buds, alterations in saliva composition, central nervous system changes, and oral microbiota dysbiosis. A comprehensive literature review was conducted to disentangle the effects of age from those of the several age-related diseases or conditions promoting TAs. Most of the included studies reported TAs in healthy elderly people, suggesting that presbygeusia is a relatively frequent condition associated with age-related changes in the absence of pathological conditions. However, the impact of TAs on dietary preferences and food choices among the elderly seems to be less relevant when compared to other factors, such as cultural, psychological, and social influences. In conclusion, presbygeusia exists even in the absence of comorbidities or drug side effects, but its impact on dietary choices in the elderly is likely modest.

Atrial fibrillation in heart failure: drugs or ablation?

Atrial fibrillation (AF) and heart failure (HF) frequently coexist and mutually exert negative influences with important clinical implications. Although there is evidence that restoring and maintaining sinus rhythm may have favourable clinical effects in patients with HF, there is no evidence of a survival benefit with pharmacological antiarrhythmic intervention compared with a heart rate control strategy. In these patients, transcatheter ablation (CA) of AF represents a procedure with an excellent safety profile in centres with expertise and a high volume of interventions. However, in the absence of definite evidence of benefit on major clinical end-points that can be generalized to the heterogeneous population with AF and HF, the option of CA should be discussed and shared with the patient, and mainly considered in patients with conditions that are associated with a greater prospect of clinical benefit, such as 'young' age (65-70 years), good health conditions and few or no comorbidities, recent onset of HF and AF (especially if with high heart rate), left atrial volume not excessively compromised (<55 mm in diameter), and without evidence of substantial fibrotic remodelling, left ventricular ejection fraction (LVEF) >25%, including HF with preserved EF (HFpEF).

The Carers' Needs Assessment for Dementia (CNA-D): a validation study in the Italian population.

BACKGROUND: Dementia has devastating consequences for families with important physical, psychological, social, and financial effects. Evaluation of caregiver's needs may be an important step to reduce the burden of family caregivers of dementia patients. An Austrian scale, the Carers' Needs Assessment for Dementia, is now available for measuring the caregiver's needs. The aim of our study was to evaluate the psychometric properties of the Italian version of the CNA-D (iCNA-D). METHODS: A sample of 214 voluntary caregivers of dementia patients was recruited at the Department of Neuroscience, University of Turin (Italy). All participants were administered the iCNA-D. Validity and reliability of the instrument were evaluated using Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Symptom Checklist-90 (SCL-90), and the Italian version of Zarit Burden Interview (I-ZBI). RESULTS: The most common unmet need reported for the iCNA-D was "counseling and emotional support" (31.5%). This item demonstrates adequate reliability with moderate internal consistency for all "summary scores" of iCNA-D (α ≥ 0.75) and split-half correlation of more than 0.80 for two of them. We also found positive correlations in two out of three "summary scores" of iCNA-D and in the overall outcomes of BDI, BAI, SCL-90, and I-ZBI. CONCLUSIONS: The iCNA-D could be a valid and reliable tool for a comprehensive assessment of needs and possible social supports proposed to relatives who take care of patients with dementia. Better understanding of family caregivers' needs could improve planning of local services and reduce caregivers' perception of distress and burden.

Prevalence of obesity and diabetes in older people with sarcopenia defined according to EWGSOP2 and FNHI criteria.

BACKGROUND: Although the prevalence of sarcopenic obesity is increasing, nowadays a universally accepted definition still does not exist. Because, this clinical entity is defined as the combination of obesity and sarcopenia, the diagnosis appears to be strictly linked to criteria used for sarcopenia and the available prevalence data are not uniform. To investigate the prevalence of sarcopenic obesity in older persons according to EWGSOP2 and FNIH criteria. Second, to evaluate the prevalence of diabetes in patients with sarcopenia diagnosed by the two definitions. METHODS: Observational multicenter study performed in 2014 on older patients admitted to 12 Italian hospitals (GLISTEN Study). Data were collected through standardized questionnaires, which assessed: socio-demographic data, cognitive status, functional abilities, pharmacological therapy, comorbidities, and blood tests. Moreover, muscle mass and strength and physical performance were evaluated. RESULTS: Six hundred and ten were included in the analyses. Among sarcopenic patients, the prevalence of sarcopenic obesity was 30.8% with FNIH and 0% with EWGSOP2 criteria. According to EWGSOP2 criteria, 23.7% of sarcopenic and 30.8% of non-sarcopenic patients were affected by diabetes (p = 0.101); otherwise, using FNIH criteria, 36.3% of sarcopenic and 26.9% of non-sarcopenic patients were diabetic (p = 0.030). After adjustment for potential confounders, diabetic patients had a 73% higher probability of being sarcopenic according to FNIH criteria (OR 1.73; 95% CI 1.13-2.64). CONCLUSIONS: The EWGSOP2 and FNIH sarcopenia criteria are differently related to the prevalence of obesity and diabetes. The EWGSOP2 criteria seem to be not suitable to identify people with sarcopenic obesity.

Percutaneous coronary intervention of unprotected left main and bifurcation in octogenarians: Subanalysis from RAIN (veRy thin stents for patients with left mAIn or bifurcatioN in real life).

OBJECTIVE: Outcomes of complex percutaneous coronary interventions (PCIs) in older patients are still debated. The aim of the study was to evaluate clinical outcomes of Octogenarian patients treated with ultrathinstents on left main or on coronary bifurcations, compared with younger patients. METHODS: All consecutive patients presenting a critical lesion of an unprotected left main (ULM) or a bifurcation and treated with very thin stents were included in the RAIN (veRy thin stents for patients with left mAIn or bifurcatioN in real life) registry and divided into octogenarians group (OG, 551 patients) and nonoctogenarians (NOGs, 2,453 patients). Major adverse cardiovascular event (MACE), a composite end point of all-cause death, nonfatal myocardial infarction (MI), target lesion revascularization (TLR), and stent thrombosis (ST), was the primary endpoint, while MACE components, cardiovascular (CV) death, and target vessel revascularization (TVR) were the secondary ones. RESULTS: Indication for PCI was acute coronary syndrome in 64.7% of the OG versus 53.1% of the NOG. Severe calcifications and a diffuse disease were significantly more in OG. After a follow-up of 15.2 ± 10.3 months, MACEs were higher in the OG than in the NOG patients (OG 19.1% vs. NOG 11.2%, p < .001), along with MI (OG 6% vs. NOG 3.4%, p = .002) and all-cause death (OG 14% vs. NOG 4.3%, p < .001). In contrast, no significant difference was detected in CV-death (OG 5.1% vs. NOG 4%, p = .871), TVR/TLR, or ST. At multivariate analysis, age was not an independent predictor of MACE (OR 1.02 CI 95% 0.76-1.38), while it was for all-cause death, along with diabetes, GFR < 60 ml/min, and ULM disease. DISCUSSION: Midterm outcomes of complex PCI in OG are similar to those of younger patients. However, due to the higher non-CV death rate, accurate patient selection is mandatory.

Accuracy of the PARIS score and PCI complexity to predict ischemic events in patients treated with very thin stents in unprotected left main or coronary bifurcations.

BACKGROUND: The PARIS risk score (PARIS-rs) and percutaneous coronary intervention complexity (PCI-c) predict clinical and procedural residual ischemic risk following PCI. Their accuracy in patients undergoing unprotected left main (ULM) or bifurcation PCI has not been assessed. METHODS: The predictive performances of the PARIS-rs (categorized as low, intermediate, and high) and PCI-c (according to guideline-endorsed criteria) were evaluated in 3,002 patients undergoing ULM/bifurcation PCI with very thin strut stents. RESULTS: After 16 (12-22) months, increasing PARIS-rs (8.8% vs. 14.1% vs. 27.4%, p < .001) and PCI-c (15.2% vs. 11%, p = .025) were associated with higher rates of major adverse cardiac events ([MACE], a composite of death, myocardial infarction [MI], and target vessel revascularization), driven by MI/death for PARIS-rs and target lesion revascularization/stent thrombosis for PCI-c (area under the curves for MACE: PARIS-rs 0.60 vs. PCI-c 0.52, p-for-difference < .001). PCI-c accuracy for MACE was higher in low-clinical-risk patients; while PARIS-rs was more accurate in low-procedural-risk patients. ≥12-month dual antiplatelet therapy (DAPT) was associated with a lower MACE rate in high PARIS-rs patients, (adjusted-hazard ratio 0.42 [95% CI: 0.22-0.83], p = .012), with no benefit in low to intermediate PARIS-rs patients. No incremental benefit with longer DAPT was observed in complex PCI. CONCLUSIONS: In the setting of ULM/bifurcation PCI, the residual ischemic risk is better predicted by a clinical risk estimator than by PCI complexity, which rather appears to reflect stent/procedure-related events. Careful procedural risk estimation is warranted in patients at low clinical risk, where PCI complexity may substantially contribute to the overall residual ischemic risk.

The relationship between frailty and delirium: insights from the 2017 Delirium Day study.

BACKGROUND: although frailty and delirium are among the most frequent and burdensome geriatric syndromes, little is known about their association and impact on short-term mortality. OBJECTIVE: to examine, in hospitalized older persons, whether frailty is associated with delirium, and whether these two conditions, alone or in combination, affect these patients' 30-day survival. DESIGN: observational study nested in the Delirium Day project, with 30-day follow-up. SETTING: acute medical wards (n = 118) and rehabilitation wards (n = 46) in Italy. SUBJECTS: a total of 2,065 individuals aged 65+ years hospitalized in acute medical (1,484 patients, 71.9%) or rehabilitation (581 patients, 28.1%) wards. METHODS: a 25-item Frailty Index (FI) was created. Delirium was assessed using the 4AT test. Vital status was ascertained at 30 days. RESULTS: overall, 469 (22.7%) patients experienced delirium on the index day and 82 (4.0%) died during follow-up. After adjustment for potential confounders, each FI score increase of 0.1 significantly increased the odds of delirium (odds ratio, OR: 1.66 [95% CI: 1.45-1.90]), with no difference between the acute (OR: 1.65 [95% CI: 1.41-1.93]) and rehabilitation ward patients (OR: 1.71 [95% CI: 1.27-2.30]). The risk of dying during follow-up also increased significantly for every FI increase of 0.1 in the overall population (OR: 1.65 [95% CI: 1.33-2.05]) and in the acute medical ward patients (OR: 1.61 [95% CI: 1.28-2.04]), but not in the rehabilitation patients. Delirium was not significantly associated with 30-day mortality in either hospital setting. CONCLUSIONS: in hospitalized older patients, frailty is associated with delirium and with an increased risk of short-term mortality.

Telemedicine-assisted care of an older patient with COVID-19 and dementia: bridging the gap between hospital and home.

Hospital at Home (HaH) has been proposed as a solution to relieve pressure on hospital beds during the COVID-19 pandemic; however, caregivers' feelings of inadequacy and concerns on the need for tighter clinical monitoring might lead to unnecessary and potentially harmful hospital admissions in frail older patients with mild or atypical COVID-19. Here we report the case of a 91-year old woman with severe dementia and atypical COVID-19 that could be successfully managed by our HaH thanks to her highly motivated caregivers and the support of a telemedicine solution (TMS) to provide caregiver training and support as well as supplementary telemonitoring. Despite some well-known issues on TMS use, the hybrid in-person and tele-visit approach of TMS-assisted HaH could help to create a "secure" environment, empowering caregivers to manage frail older adults with COVID-19 at home, avoiding unnecessary admissions to closed wards and their negative physical, functional and psychological outcomes.

Delirium symptoms duration and mortality in SARS-COV2 elderly: results of a multicenter retrospective cohort study.

BACKGROUND: Since the occurrence of the SARS-COV2 pandemic, there has been an increasing interest in investigating the epidemiology of delirium. Delirium is frequent in SARS-COV2 patients and it is associated with increased mortality; however, no information is available on the association between delirium duration in SARS-COV2 patients and related outcomes. AIMS: The aim of this study is to investigate the association between the duration of delirium symptoms and in-hospital mortality in older patients with SARS-COV2 infection. METHODS: Retrospective cohort study of patients 65 years of age and older with SARS-CoV 2 infection admitted to two acute geriatric wards and one rehabilitation ward. Delirium symptoms duration was assessed retrospectively with a chart-based validated method. In-hospital mortality was ascertained via medical records. RESULTS: A total of 241 patients were included. The prevalence of delirium on admission was 16%. The median number of days with delirium symptoms was 4 (IQR 2-6.5) vs. 0 (IQR 0-2) in patients with and without delirium on admission. In the multivariable Cox regression model, each day with a delirium symptom in a patient with the same length of stay was associated with a 10% increase in in-hospital mortality (Hazard ratio 1.1, 95% Confidence interval 1.01-1.2; p = 0.03). Other variables associated with increased risk of in-hospital death were age, comorbidity, CPAP, CRP levels and total number of drugs on admission. CONCLUSIONS: The study supports the necessity to establish protocols for the monitoring and management of delirium during emergency conditions to allow an appropriate care for older patients.

Oral anticoagulant therapy in atrial fibrillation older patients with previous bleeding.

Oral anticoagulant therapy (OAT) with direct oral anticoagulant (DOACs) is the established treatment to reduce thromboembolic risk in patients with atrial fibrillation (AF). Bleeding risk scores are useful to identify and correct factors associated with bleeding risk in AF patients on OAT. However, the clinical scenario is more complex in patients with previous bleeding event, and the decision about whether and when starting or re-starting OAT in these patients remains a contentious issue. Major bleeding is associated with a subsequent increase in both short- and long-term mortality, and even minimal bleeding may have prognostic importance because it frequently leads to disruption of antithrombotic therapy. There is an unmet need for guidance on how to manage antithrombotic therapy after bleeding has occurred. While waiting for observational and randomized data to accrue, this paper offers a perspective on managing antithrombotic therapy after bleeding in older patients with AF.

The association of indwelling urinary catheter with delirium in hospitalized patients and nursing home residents: an explorative analysis from the "Delirium Day 2015".

BACKROUND: Use of indwelling urinary catheter (IUC) in older adults has negative consequences, including delirium. AIM: This analysis, from the "Delirium Day 2015", a nationwide multicenter prevalence study, aim to evaluate the association of IUC with delirium in hospitalized and Nursing Homes (NHs) patients. METHODS: Patients underwent a comprehensive geriatric assessment, including the presence of IUC; inclusion criteria were age > 65 years, being Italian speaker and providing informed consent; exclusion criteria were coma, aphasia, end-of-life status. Delirium was assessed using the 4AT test (score ≥ 4: possible delirium; scores 1-3: possible cognitive impairment). RESULTS: Among 1867 hospitalized patients (mean age 82.0 ± 7.5 years, 58% female), 539 (28.9%) had IUC, 429 (22.9%) delirium and 675 (36.1%) cognitive impairment. IUC was significantly associated with cognitive impairment (OR 1.60, 95% CI 1.19-2.16) and delirium (2.45, 95% CI 1.73-3.47), this latter being significant also in the subset of patients without dementia (OR 2.28, 95% CI 1.52-3.43). Inattention and impaired alertness were also independently associated with IUC. Among 1454 NHs residents (mean age 84.4 ± 7.4 years, 70.% female), 63 (4.3%) had IUC, 535 (36.8%) a 4AT score ≥ 4, and 653 (44.9%) a 4AT score 1-3. The multivariate logistic regression analysis did not show a significant association between 4AT test or its specific items with IUC, neither in the subset of patients without dementia. DISCUSSION: We confirmed a significant association between IUC and delirium in hospitalized patients but not in NHs residents. CONCLUSION: Environmental and clinical factors of acute setting might contribute to IUC-associated delirium occurrence.

Polypharmacy and sarcopenia in hospitalized older patients: results of the GLISTEN study.

BACKGROUND: Recently the Berlin Aging Study II (BASE-II) showed that polypharmacy is associated with clinically relevant sarcopenia among community-dwelling older persons. Here we report findings from the GLISTEN study about the association of polypharmacy with sarcopenia among older medical in-patients. METHODS: The GLISTEN study investigated prevalence and clinical correlates of sarcopenia in older patients admitted to geriatric and internal medicine acute care wards of 12 Italian hospitals. RESULTS: In this sample of older medical in-patients with high prevalence of sarcopenia (34.7%) and polypharmacy (70.2%) we did not observe a significant association of polypharmacy with sarcopenia. CONCLUSIONS: Present findings demonstrate that the association of polypharmacy with sarcopenia, observed in the BASE-II study, is not evident in the GLISTEN sample, being our patients significantly older, more multi-morbid, with high prevalence of sarcopenia and polypharmacy, suggesting that this association might vary according to the heterogeneous health, functional, and nutritional characteristics of older people.

A Point Prevalence Study of Delirium in Italian Nursing Homes.

BACKGROUND: Delirium is a common geriatric syndrome. Few studies have been conducted in nursing home (NH) residents. The aim of this project was to perform a point prevalence study of delirium in Italian NHs. METHODS: Data collected in 71 NHs are presented. Inclusion criteria were age ≥65 years and native Italian speaker. Exclusion criteria were coma, aphasia, and end-of-life status. Sociodemographic and medical data were recorded. Delirium was assessed using the Assessment Test for Delirium and Cognitive Impairment (4-AT). Patients with a 4-AT score ≥4 were considered to have delirium. Motor subtype was evaluated using the Delirium Motor Subtype Scale (DMSS). RESULTS: A total of 1,454 patients were evaluated (mean age 84.4 ± 7.4 years, 70.2% female), of whom 535 (36.8%) had delirium. In multivariate logistic regression analysis, variables significantly associated with delirium were education (OR 0.94, 95% CI 0.91-0.97), dementia (OR 3.12, 95% CI 2.38-4.09), functional dependence (OR 6.13, 95% CI 3.08-12.19 for ADL score 0; OR 1.99, 95% CI 1.03-3.84 for ADL score 1-5), malnutrition (OR 4.87, 95% CI 2.68-8.84), antipsychotics (OR 2.40, 95% CI 1.81-3.18), and physical restraints (OR 2.48, 95% CI 1.71-3.59). CONCLUSION: Delirium is common in older NH residents. Simple assessment tools might facilitate its recognition in this vulnerable population.

Extent of, and variables associated with, blood pressure variability among older subjects.

BACKGROUND: Blood pressure variability (BPV) may have prognostic implications for cardiovascular risk and cognitive decline; however, BPV has yet to be studied in old and very old people. AIMS: Aim of the present study was to evaluate the extent of BPV and to identify variables associated with BPV among older subjects. METHODS: A retrospective study of patients aged ≥ 65 years who underwent 24-h ambulatory blood pressure monitoring (ABPM) was carried out. Three different BPV indexes were calculated for systolic and diastolic blood pressure (SBP and DBP): standard deviation (SD), coefficient of variation (CV), and average real variability (ARV). Demographic variables and use of antihypertensive medications were considered. RESULTS: The study included 738 patients. Mean age was 74.8 ± 6.8 years. Mean SBP and DBP SD were 20.5 ± 4.4 and 14.6 ± 3.4 mmHg. Mean SBP and DBP CV were 16 ± 3 and 20 ± 5%. Mean SBP and DBP ARV were 15.7 ± 3.9 and 11.8 ± 3.6 mmHg. At multivariate analysis older age, female sex and uncontrolled mean blood pressure were associated with both systolic and diastolic BPV indexes. The use of calcium channel blockers and alpha-adrenergic antagonists was associated with lower systolic and diastolic BPV indexes, respectively. CONCLUSIONS: Among elderly subjects undergoing 24-h ABPM, we observed remarkably high indexes of BPV, which were associated with older age, female sex, and uncontrolled blood pressure values.

Effects of oral anticoagulant therapy in older medical in-patients with atrial fibrillation: a prospective cohort observational study.

BACKGROUND: Uncertainties about efficacy and safety of oral anticoagulant therapy (OAT) among older and frail medical patients with atrial fibrillation (AF) largely contribute to under-prescription of these drugs. AIMS: In this prospective observational cohort study, we investigated mortality, and ischemic and hemorrhagic events, in hospital-discharged older patients with AF. METHODS: Stroke and bleeding risk were evaluated using CHA2DS2-VASC and HAS-BLED scores. Comorbidity, frailty, cognitive and nutritional status and functional autonomy were evaluated using standardized scales. Independent associations between clinical variables, including OAT use, and all-cause mortality, fatal and non-fatal ischemic and hemorrhagic events, were evaluated. Further clinical outcomes comparison between patients treated with OAT and those untreated was performed after adjustment for significant differences in patient baseline characteristics with propensity score matching. RESULTS: Of 452 patients included (mean age 81.6 years, 54.9 % women, roughly 30 % cognitively impaired and/or functionally dependent, mean CHA2DS2-VASC and HAS-BLED scores 4.6 and 2.8, respectively), 151 (33.4 %) died during a mean follow-up period of 300.5 days; ischemic and hemorrhagic stroke occurred in 4.0 and 0.4 % of patients, respectively, and major bleedings in 6.2 %. DISCUSSION: After multivariate analysis, OAT at discharge was associated with lower overall mortality and reduced occurrence of ischemic stroke, the first finding being confirmed in propensity score matched analysis. CONCLUSIONS: Among older vulnerable AF patients with high post discharge death rate, OAT was associated, among other multiple factors, with reduced mortality and lower occurrence of ischemic stroke.

"Delirium Day": a nationwide point prevalence study of delirium in older hospitalized patients using an easy standardized diagnostic tool.

BACKGROUND: To date, delirium prevalence in adult acute hospital populations has been estimated generally from pooled findings of single-center studies and/or among specific patient populations. Furthermore, the number of participants in these studies has not exceeded a few hundred. To overcome these limitations, we have determined, in a multicenter study, the prevalence of delirium over a single day among a large population of patients admitted to acute and rehabilitation hospital wards in Italy. METHODS: This is a point prevalence study (called "Delirium Day") including 1867 older patients (aged 65 years or more) across 108 acute and 12 rehabilitation wards in Italian hospitals. Delirium was assessed on the same day in all patients using the 4AT, a validated and briefly administered tool which does not require training. We also collected data regarding motoric subtypes of delirium, functional and nutritional status, dementia, comorbidity, medications, feeding tubes, peripheral venous and urinary catheters, and physical restraints. RESULTS: The mean sample age was 82.0 ± 7.5 years (58 % female). Overall, 429 patients (22.9 %) had delirium. Hypoactive was the commonest subtype (132/344 patients, 38.5 %), followed by mixed, hyperactive, and nonmotoric delirium. The prevalence was highest in Neurology (28.5 %) and Geriatrics (24.7 %), lowest in Rehabilitation (14.0 %), and intermediate in Orthopedic (20.6 %) and Internal Medicine wards (21.4 %). In a multivariable logistic regression, age (odds ratio [OR] 1.03, 95 % confidence interval [CI] 1.01-1.05), Activities of Daily Living dependence (OR 1.19, 95 % CI 1.12-1.27), dementia (OR 3.25, 95 % CI 2.41-4.38), malnutrition (OR 2.01, 95 % CI 1.29-3.14), and use of antipsychotics (OR 2.03, 95 % CI 1.45-2.82), feeding tubes (OR 2.51, 95 % CI 1.11-5.66), peripheral venous catheters (OR 1.41, 95 % CI 1.06-1.87), urinary catheters (OR 1.73, 95 % CI 1.30-2.29), and physical restraints (OR 1.84, 95 % CI 1.40-2.40) were associated with delirium. Admission to Neurology wards was also associated with delirium (OR 2.00, 95 % CI 1.29-3.14), while admission to other settings was not. CONCLUSIONS: Delirium occurred in more than one out of five patients in acute and rehabilitation hospital wards. Prevalence was highest in Neurology and lowest in Rehabilitation divisions. The "Delirium Day" project might become a useful method to assess delirium across hospital settings and a benchmarking platform for future surveys.
