An algorithm for the early diagnosis and correct approach to dementia management: results of a multiprofessional team.

BACKGROUNG: The early identification of cognitive disorder is a primary scope, because it could reduce the rate of severe cognitive impairment and thus contribute to reduce healthcare costs in the next future. AIMS: The present paper aimed to build a virtuous diagnostic path of cognitive impairment, highlighting all the professionalism that can serve this purpose. METHODS: The Delphi method was used by the experts, who reviewed the information available during each meeting related to the following topics: early diagnosis of cognitive impairment, definition of Mild Cognitive Impairment, unmet needs in post-stroke patients, critical decision-making nodes in complex patients, risk factors, neuropsychological, imaging diagnosis, blood tests, the criteria for differential diagnosis and the possible treatments. RESULTS: The discussion panels analyzed and discussed the available evidences on these topics and the related items. At each meeting, the activities aimed at the creation of a diagnostic-welfare flow chart derived from the proposal of the board and the suggestions of the respondents. Subsequently, the conclusions of each panel were written, and the study group reviewed them until a global consensus was reached. Once this process was completed, the preparation of the final document was carried out. CONCLUSIONS: Eventually, we built an algorithm for the early diagnosis and treatment, the risk factors, with the possible differences among the different kinds of dementia.

Frailty, psychological well-being, and social isolation in older adults with cognitive impairment during the SARS-CoV-2 pandemic: data from the GeroCovid initiative.

BACKGROUND: The containment measures linked to the COVID-19 pandemic negatively affected the phyco-physical well-being of the population, especially older adults with neurocognitive disorders (NCDs). This study aims to evaluate whether the frailty of NCD patients was associated with different changes in multiple health domains, in particular in relation to loneliness and social isolation, pre- and post-lockdown. MATERIALS AND METHODS: Patients were recruited from 10 Italian Centers for Cognitive Disorders and Dementia. Data were collected in the pre-pandemic period (T0), during the pandemic lockdown (T1), and 6-9 months post-lockdown (T2). The UCLA Loneliness Scale-3, Activities of Daily Living (ADL), Instrumental ADL (IADL), Mini-Mental State Examination, and Neuropsychiatric Inventory (NPI) were administered. Caregivers' burden was also tested. Patients were categorized as non-frail, pre-frail, and frail according to the Fatigue, Resistance, Ambulation, Illness, and Loss of Weight scale. RESULTS: The sample included 165 subjects (61.9% women, mean age 79.5 ± 4.9 years). In the whole sample, the ADL, IADL, and NPI scores significantly declined between T0 and T2. There were no significative variations in functional and cognitive domains between the frail groups. During lockdown we recorded higher Depression Anxiety Stress Scales and Perceived Stress Scale scores in frail people. In multivariable logistic regression, frailty was associated with an increase in social isolation, and a loss of IADL. CONCLUSIONS: We observed a global deterioration in functional and neuro-psychiatric domains irrespective of the degree of frailty. Frailty was associated with the worsening of social isolation during lockdown. Frail patients and their caregivers seemed to experience more anxiety and stress disorders during SARS-CoV-2 pandemic.

Management of Older Outpatients during the COVID-19 Pandemic: The GeroCovid Ambulatory Study.

OBJECTIVES: The GeroCovid Study is a multi-setting, multinational, and multi-scope registry that includes the GeroCovid home and outpatients' care cohort. The present study aims to evaluate whether outpatient and home care services with remote monitoring and consultation could mitigate the impact of the COVID-19 pandemic on mental and affective status, perceived well-being, and personal capabilities of outpatients and home care patients with cognitive disorders. METHODS: Prospectively recorded patients in an electronic web registry provided by BlueCompanion Ltd. Up to October 31, 2020, the sample included 90 patients receiving regular care from the Center for Cognitive Disorders and Dementia in Catanzaro Lido, Italy. It was made of 52 ambulatory outpatients and 38 home care patients, mean age 83.3 ± 7.54 years. Participants underwent a multidimensional assessment at baseline (T0) and after 90 days (T1). For each patient, we administered the Mini-Mental State Examination (MMSE) for cognitive functions, the Activities of Daily Living (ADL) and Instrumental ADL (IADL) scales for functional capabilities, the Cumulative Illness Rating Scale (CIRS) for comorbidities and their impact on patients' health, the 5-items Geriatric Depression Scale (GDS) for mood, and the Euro Quality of Life (EuroQoL) for perceived quality of life. Contacts with both ambulatory and home care patients were managed in person or via telephone, preferably through video calls (WhatsApp or FaceTime). RESULTS: Contacts with patients were kept at T0 through telephone. At T1, visits were made in person for over 95% out of the cases. The ADL, IADL, CIRS, GDS, MMSE, and EuroQoL changed slightly between T0 and T1. Most of the patients were clinically stable over time on the majority of the scales explored, but behavioral changes were found in 24.4% of patients and anxiety and insomnia in 17.7% of patients. CONCLUSION: Our study suggests that contacts through telephone and video consultations are likely associated with a health status preservation of the patients.

Computed tomography findings and prognosis in older COVID-19 patients.

BACKGROUND: In older and multimorbid patients, chronic conditions may affect the prognostic validity of computed tomography (CT) findings in COVID-19. This study aims at assessing to which extent CT findings have prognostic implications in COVID-19 older patients. METHODS: Hospitalized COVID-19 patients aged 60 years or more enrolled in the multicenter, observational and longitudinal GeroCovid study who underwent chest CT were included. Patients were stratified by tertiles of age and pneumonia severity to compare CT findings. Hierarchical clustering based on CT findings was performed to identify CT-related classificatory constructs, if any. The hazard ratio (HR) of mortality was calculated for individual CT findings and for clusters, after adjusting for potential confounders. RESULTS: 380 hospitalized COVID-19 patients, with a mean age of 78 (SD:9) years, underwent chest CT scan. Ground glass opacity (GGO), consolidation, and pleural effusion were the three most common CT findings, with GGO prevalence decreasing from younger to older patients and pleural effusion increasing. More severe the pneumonia more prevalent were GGO, consolidation and pleural effusion. HR of mortality was 1.94 (95%CI 1.24-3.06) for pleural effusion and 13 (95%CI 6.41-27) for cluster with a low prevalence of GGO and a high prevalence of pleural effusion ("LH"), respectively. Out of the three CT based clusters, "LH" was the only independent predictor in the multivariable model. CONCLUSIONS: Pleural effusion qualifies as a distinctive prognostic marker in older COVID-19 patients. Research is needed to verify whether pleural effusion reflects COVID-19 severity or a coexisting chronic condition making the patient at special risk of death.

Atrial fibrillation and COVID-19 in older patients: how disability contributes to shape the risk profile. An analysis of the GeroCovid registry.

BACKGROUND AND AIMS: Atrial fibrillation (AF) is often complicated by disabling conditions in the elderly. COVID-19 has high mortality in older people. This study aimed at evaluating the relationship of pre-infection AF with characteristics and survival of older COVID-19 patients. METHODS: We retrospectively analyzed inpatients aged ≥ 60 years enrolled in GeroCovid Observational, a multicenter registry endorsed by the Italian and the Norwegian Societies of Gerontology and Geriatrics. Pre-COVID-19 sociodemographic, functional, and medical data were systematically collected, as well as in-hospital mortality. RESULTS: Between March and June 2020, 808 COVID-19 subjects were enrolled (age 79 ± 9 years; men 51.7%). The prevalence of AF was 21.8%. AF patients were older (82 ± 8 vs. 77 ± 9 years, p < 0.001), had a higher CHA2DS2-VASc score (4.1 ± 1.5 vs. 3.2 ± 1.5, p < 0.001) and were more likely to present almost all comorbidities. At multivariable analysis, advanced age, white blood cell count, the presence of heart and peripheral artery diseases were significantly associated with the presence of AF. In-hospital mortality was higher in AF patients (36.9 vs. 27.5%; OR = 1.55, 95% CI = 1.09-2.20; p = 0.015). A decision tree analysis showed that, in AF subjects, preserved functional status at admission was the most important factor associated with survival. In patients without AF, baseline COVID-19 severity was the most relevant variable related to clinical prognosis. CONCLUSIONS: AF is frequent in older patients with COVID-19, in whom it associates with clinical complexity and high mortality. Pre-infection disability shapes the prognosis of this extremely vulnerable segment of hospitalized subjects. CLINICAL TRIAL REGISTRATION: GeroCovid Observational was registered at www.clinicaltrials.gov (NCT04379440).

The risk of polypharmacy and potentially inappropriate drugs in residential care dementia patients: tips from the PharE study.

AIMS: The aims of the present study, conducted in two regions of Italy, Calabria and Piedmont, were to assess the use of inappropriate drugs according to the Beers Criteria and to study the possible drug-drug interactions. METHODS: Data were obtained retrospectively from 972 residential care patients between 2016 and 2018. Mean age was 82.4 ± 8.4 years, with a prevalence of women (64.8%). Activities of daily living, instrumental activities of daily living, Mini-Mental State Examination, Cumulative Illness Rating Scale, Neuropsychiatric Inventory Scale and number and kind of drugs were recorded. A classification of potential inappropriate drugs was made according to the Beers criteria. Data were collected through an Excel file able to gather the main information. In the case of suspected adverse event, Naranjo Scale was applied. The study of possible drug-drug interactions was made by Micromedex 2.0. RESULTS: Functional and cognitive impairments, comorbidities and number of drugs were assessed. The bivariate relationship between number of drugs and glomerular filtration rate assessed by CKD-EPI showed that the higher was the number of drugs used, the worst was kidney function assessment (p = 0.0001). The most frequent inappropriate drugs were anticholinergic drugs, tricyclics antidepressants, long-half-life benzodiazepines, antipsychotics and proton pump inhibitors. CONCLUSIONS: These data are very interesting and show the need for an accurate choice of drugs in elderly people and for starting a wise deprescribing procedure.

Neuropsychiatric clinical manifestations in elderly patients treated with hydroxychloroquine: a review article.

Little is known about the development of psychosis during hydroxychloroquine (HCQ) treatment, especially in elderly patients affected by rheumatic diseases, with multiple comorbidities and treatments. To summarize the available evidence on HCQ-induced psychosis in elders, we performed a literature review. Additionally, individual case safety reports sent to the European Pharmacovigilance database (EudraVigilance) with HCQ as suspected drug and related to adverse events belonging to the System Organ Class 'Psychiatric disorders' were shown. Over the years, evidence was published about the risk of neuropsychiatric clinical manifestations during HCQ treatment for rheumatic diseases, but few of them were related to elderly patients. These adverse events can include less severe clinical manifestations such as affect lability and nervousness or more severe conditions such as actual psychosis and suicidal tendencies, which frequency are actually unknown. The presence of risk factors in these patients may precipitate HCQ-induced psychosis and their precocious detection could be associated with a risk minimization. Among predisposing risk factors, there are the co-exposure to interacting drugs, alcohol intake, familial history of psychiatric diseases, female gender, and the concomitant use of low-dose glucocorticoids. In some cases it was possible to reverse psychotic behaviour with the antipsychotic treatment or with HCQ suspension.

Two-Thirds Lip Defects: A New Combined Reconstructive Technique for Patients With Epithelial Cancer.

BACKGROUND: The lips are a common site prone to squamous cell carcinomas, which arise in the facial region. There are different techniques to reconstruct the excised lip region, according to dimensions, area, and position of the tumor. The authors describe a new technique of lip reconstruction born from a combination between a nasolabial flap and adipose tissue transplant. METHODS: The study was lead in the Plastic and Reconstructive Surgery Department of the University of Catanzaro. It includes 10 patients with squamous and basal cell carcinomas that interested lower or upper lip. The authors used a nasolabial flap to reconstruct two-thirds of the excised lip. All patients were staged and resulted free of disease. As a result of surgery, deformities and depressions persisted in 5 patients. This induced the authors to subject them to transplantation of adipose tissue to maximize results. Aesthetic and functional evaluation was performed with the Patient and Observer Scar Assessment Scale v 2.0 and drooling rating scale questionnaires. Moreover, an anthropometric analysis was performed in patients treated with fat transplant. Data were analyzed using Wilcoxon signed-rank test. RESULTS: All patients had an acceptable aesthetic and functional outcome. Oral competence, sensation, and movements of the area were adequate and aesthetic was good. Adipose tissue transplant compared with surgery alone, determine a real modification of various parameters, that was statistically significant (P = 0.043) to our analysis. CONCLUSIONS: The inverted nasolabial flap is versatile and simple. This technique allows to repair large lip defects by maintaining the eurythmia of the face. Autologous fat transplant is a favorable filler. Our data show that surgery alone is unable to restore face eurythmia after a tumor excision. Adipose tissue transplant allows to reach this goal. These 2 techniques, together, may significantly modify the functional and aesthetic result of the lip reconstruction, ensuring an optimal long-term result.

Use and safety of antipsychotics in behavioral disorders in elderly people with dementia.

In recent years, the use of antipsychotics has been widely debated for reasons concerning their safety in elderly patients affected with dementia. To update the use of antipsychotics in elderly demented people, a MEDLINE search was conducted using the following terms: elderly, conventional and atypical antipsychotics, adverse events, dementia, and behavioral and psychotic symptoms in dementia (BPSD). Owing to the large amounts of studies on antipsychotics, we mostly restricted the field of research to the last 10 years. Conventional antipsychotics have been widely used for BPSD; some studies showed they have an efficacy superior to placebo only at high doses, but they are associated with several and severe adverse effects. Atypical antipsychotics showed an efficacy superior to placebo in randomized studies in BPSD treatment, with a better tolerability profile versus conventional drugs. However, in 2002, trials with risperidone and olanzapine in elderly patients affected with dementia-related psychoses suggested the possible increase in cerebrovascular adverse events. Drug regulatory agencies issued specific recommendations for underlining that treatment of BPSD with atypical antipsychotics is "off-label." Conventional antipsychotics showed the same likelihood to increase the risk of death in the elderly as atypical agents, and they should not replace the atypical agents discontinued by Food and Drug Administration warnings. Before prescribing an antipsychotic drug, the following are factors to be seriously considered: the presence of cardiovascular diseases, QTc interval on electrocardiogram, electrolytic imbalances, familiar history for torsades des pointes, concomitant treatments, and use of drugs able to lengthen QTc. Use of antipsychotics in dementia needs a careful case-by-case assessment, together with the possible drug-drug, drug-disease, and drug-food interactions.

Citicoline: A Cholinergic Precursor with a Pivotal Role in Dementia and Alzheimer's Disease.

Background: Citicoline is a naturally occurring compound with pleiotropic effects on neuronal function and cognitive processes. Objective: Based on previous studies, which shed light on the positive effects of citicoline 1 g when combined with acetylcholinesterase inhibitors (AChEIs) and/or memantine, we further investigated the benefits of citicoline in combination therapy in Alzheimer's disease and mixed dementia. Methods: We integrated the datasets of CITIMEM and CITIDEMAGE, increasing the overall sample size to enhance statistical power. We analyzed data from these two investigator-initiated studies involving 295 patients. The primary outcome was the assessment over time of the effects of combined treatment versus memantine given alone or AChEI plus memantine on cognitive functions assessed by Mini-Mental State Examination (MMSE). The secondary outcomes were the influence of combined treatment on daily life functions, mood, and behavioral symptoms assessed by activities of daily life (ADL) and instrumental ADL, Geriatric Depression Scale, and Neuropsychiatric Inventory Scale. One-hundred-forty-three patients were treated with memantine and/or AChEI (control group), and 152 patients were treated with memantine and/or AChEI plus citicoline 1 g/day orally (Citicoline group). Results: A significant difference in MMSE score was found in the average between the two groups of treatment at 6 and 12 months. Conclusions: This study confirmed the effectiveness of combined citicoline treatment in patients with mixed dementia and Alzheimer's disease, with a significant effect on the increase of MMSE score over time. The treated group also showed a significant reduction in the Geriatric Depression Scale and a significant increase in the instrumental ADL scale.

Deprescribing in Older Poly-Treated Patients Affected with Dementia.

Polypharmacy is an important issue in older patients affected by dementia because they are very vulnerable to the side effects of drugs'. Between October 2021 and September 2022, we randomly assessed 205 old-aged outpatients. The study was carried out in a Center for Dementia in collaboration with a university center. The primary outcomes were: (1) deprescribing inappropriate drugs through the Beers and STOPP&START criteria; (2) assessing duplicate drugs and the risk of iatrogenic damage due to drug-drug and drug-disease interactions. Overall, 69 men and 136 women (mean age 82.7 ± 7.4 years) were assessed. Of these, 91 patients were home care patients and 114 were outpatient. The average number of the drugs used in the sample was 9.4 drugs per patient; after the first visit and the consequent deprescribing process, the average dropped to 8.7 drugs per patient (p = 0.04). Overall, 74 potentially inappropriate drugs were used (36.1%). Of these, long half-life benzodiazepines (8.8%), non-steroidal anti-inflammatory drugs (3.4%), tricyclic antidepressants (3.4%), first-generation antihistamines (1.4%), anticholinergics (11.7%), antiplatelet drugs (i.e., ticlopidine) (1.4%), prokinetics in chronic use (1.4%), digoxin (>0.125 mg/day) (1.4%), antiarrhythmics (i.e., amiodarone) (0.97%), and α-blockers (1.9%) were included. The so-called "duplicate" drugs were overall 26 (12.7%). In total, ten potentially dangerous prescriptions were found for possible interactions (4.8%). We underline the importance of checking all the drugs taken periodically and discontinuing drugs with the lowest benefit-to-harm ratio and the lowest probability of adverse reactions due to withdrawal. Computer tools and adequately trained teams (doctors, nurses, and pharmacists) could identify, treat, and prevent possible drug interactions.

Pharmacodynamic potentiation of antiepileptic drugs' effects by some HMG-CoA reductase inhibitors against audiogenic seizures in DBA/2 mice.

It is known that the 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) are effective in both the primary and the secondary prevention of ischemic heart disease. Increasing evidence indicates that statins have protective effects in several neurological diseases including stroke, cerebral ischemia, Parkinson disease, multiple sclerosis, traumatic brain injury and epilepsy. The aim of the present research was to evaluate the effects of some HMG-CoA reductase inhibitors (i.e. lovastatin, simvastatin, atorvastatin, fluvastatin and pravastatin) commonly used for the treatment of hypercholesterolemia in the DBA/2 mice, an animal model of generalized tonic-clonic seizures. Furthermore, the co-administration of these compounds with some antiepileptic drugs (AEDs; i.e. carbamazepine, diazepam, felbamate, gabapentin, lamotrigine, levetiracetam, oxcarbazepine, phenobarbital, phenytoin, topiramate and valproate) was studied in order to identify possible positive pharmacological interactions. Simvastatin only was active against both the tonic and clonic phase of audiogenic seizures, whereas the other statins tested were only partially effective against the tonic phase with the following order of potency: lovastatin>fluvastatin>atorvastatin; pravastatin was completely ineffective up to the dose of 150mg/kg. The co-administration of ineffective doses of all statins with AEDs generally increased the potency of the latter reducing their ED50 values. In particular, simvastatin was the most active in potentiating the activity of AEDs and the combinations of statins with carbamazepine, diazepam, felbamate, lamotrigine, topiramate and valproate were the most favorable, whereas, the co-administrations with the other AEDs studied was in most cases neutral. The increase in potency was generally associated with an enhancement of motor impairment (TD50); however, the therapeutic index (TD50/ED50) of combined treatment of AEDs with statins was predominantly more favorable than control. Statins administration did not significantly affect the total plasma but, in some cases, it increased the free plasma levels and the brain concentrations of some of the AEDs studied (i.e. carbamazepine, diazepam, phenytoin and valproate); however, these alterations where not statistically significant. Therefore, with the exception of the latter compounds, we might exclude pharmacokinetic interactions and conclude that for the most of AEDs, potentiation was of pharmacodynamic nature. In conclusion, simvastatin, fluvastatin, lovastatin and atorvastatin showed an additive anticonvulsant effect when co-administered with some AEDs, most notably carbamazepine, diazepam, felbamate, lamotrigine, topiramate and valproate, implicating a possible therapeutic relevance of such drug combinations. The present results suggest that statins, besides the beneficial cardiovascular effects, might be able to affect brain areas, which might participate in the regulation of seizure susceptibility.

Somatic comorbidities and Alzheimer's disease treatment.

Therapeutic strategies in Alzheimer's disease (AD) must take into account the characteristics of elderly people, who often have somatic comorbidities. Moreover, demented patients are more frequently frailer than older people. They have a higher number of admissions to hospital, a greater prevalence of complications and an increased risk of death. Therapeutic decisions for these patients have to be approached cautiously: aging, a more elevated comorbidity/polytherapy index and frailty contribute to enhance the risk of pharmacological adverse events and drug interactions. The aim of the present study was to focus on risk-benefit profile of pharmacological therapy for AD in relation to somatic comorbidities that often affect these patients. A Medline search (from 2001 to 2012) was performed using as key words dementia, Alzheimer's disease, drug treatment, somatic comorbidities, side effects/adverse events and elderly. Cholinesterase inhibitors (ChEIs) and memantine represent the main pharmacological strategies effective in reducing the progression of cognitive decline and functional loss in AD. Many conditions very common in the elderly may restrict the use of ChEIs and/or treatment efficacy in AD patients. Memantine has a good efficacy and tolerability profile with better safety in pulmonary, cardiovascular and central nervous system comorbidities compared to ChEIs. Drug interactions with memantine are also more favorable since they concern mostly drugs not commonly used in the elderly. Only a careful evaluation of the associated somatic diseases, taking into account different drugs safety indexes and tolerability, can lead to personalized treatment management, in order to maximize drug efficacy and optimize quality of life.

Efficacy of OM-85 in Recurrent Respiratory Tract Infections.

BACKGROUND: In older patients, prevention of acute respiratory tract infections (RTIs) is challenging. Experimental studies have consistently underlined an immune-potentiating effect of the bacterial lysates product OM85, on both cellular and humoral responses. OBJECTIVE: This work aimed to assess the potential efficacy of OM-85 for RTIs' prevention in older individuals. METHODS: This explorative longitudinal study included 24 patients aged 65 years or older recruited in the GeroCovid Observational Study- home and outpatient care cohort. For the study purposes, we included 8 patients treated with OM-85 from December 2020 to June 2021 (group A), and a control group of 16 patients, matched for sex and age, who did not receive bacterial lysates (group B). RTIs were recorded from the participants' medical documentation in an e-registry from March 2020 to December 2021. RESULTS: In 2020, group A experienced a total of 8 RTIs, which affected 6 out of 8 patients (75%); group B reported 21 RTIs, with at least one event in 11 out of 16 patients (68.7%). In 2021, RTIs affected 2 out of 8 patients (25%) in group A (p < 0.02), and 13 out of 16 patients (81.2%) in group B (within this group, 5 patients had two RTIs). The RTIs' cumulative incidence over the observation period significantly differed between groups (66.7% in group A vs. 24.3% in group B; p < 0.002), as well as the decrease in RTIs frequency from 2020 to 2021. No patients in group A were affected by COVID-19 during the observation period, while among controls, two patients had SARS-CoV-2 infection, notwithstanding three doses of vaccine. CONCLUSION: This study suggests that bacterial lysates may provide clinical benefits for preventing RTIs. Additional research involving larger cohorts is required to verify the effectiveness of OM-85 in preventing RTIs in older adults.

Health trajectories in older patients hospitalized for COVID-19: Results from the GeroCovid multicenter study.

BACKGROUND: COVID-19 has disproportionately affected older adults. Yet, healthcare trajectories experienced by older persons hospitalized for COVID-19 have not been investigated. This study aimed at estimating the probabilities of transitions between severity states in older adults admitted in COVID-19 acute wards and at identifying the factors associated with such dynamics. METHODS: COVID-19 patients aged ≥60 years hospitalized between March and December 2020 were involved in the multicentre GeroCovid project-acute wards substudy. Sociodemographic and health data were obtained from medical records. Clinical states during hospitalization were categorized on a seven-category scale, ranging from hospital discharge to death. Based on the transitions between these states, first, we defined patients' clinical course as positive (only improvements), negative (only worsening), or fluctuating (both improvements and worsening). Second, we focused on the single transitions between clinical states and estimated their probability (through multistage Markov modeling) and associated factors (with proportional intensity models). RESULTS: Of the 1024 included patients (mean age 78.1 years, 51.1% women), 637 (62.2%) had a positive, 66 (6.4%) had a fluctuating, and 321 (31.3%) had a negative clinical course. Patients with a fluctuating clinical course were younger, had better mobility and cognitive levels, fewer diseases, but a higher prevalence of cardiovascular disease and obesity. Considering the single transitions, the probability that older COVID-19 patients experienced clinical changes was higher within a 10-day timeframe, especially for milder clinical states. Older age, male sex, lower mobility level, multimorbidity, and hospitalization during the COVID-19 first wave (compared with the second one) were associated with an increased probability of progressing towards worse clinical states or with a lower recovery. CONCLUSION: COVID-19 in older inpatients has a complex and dynamic clinical course. Identifying individuals more likely to experience a fluctuating clinical course and sudden worsening may help organize healthcare resources and clinical management across settings at different care intensity levels.

Clinical profile of trazodone users in a multisetting older population: data from the Italian GeroCovid Observational study.

BACKGROUND AND OBJECTIVES: Depression is highly prevalent in older adults, especially in those with dementia. Trazodone, an antidepressant, has shown to be effective in older patients with moderate anxiolytic and hypnotic activity; and a common off-label use is rising for managing behavioral and psychological symptoms of dementia (BPSD). The aim of the study is to comparatively assess the clinical profiles of older patients treated with trazodone or other antidepressants. METHODS: This cross-sectional study involved adults aged ≥ 60 years at risk of or affected with COVID-19 enrolled in the GeroCovid Observational study from acute wards, geriatric and dementia-specific outpatient clinics, as well as long-term care facilities (LTCF). Participants were grouped according to the use of trazodone, other antidepressants, or no antidepressant use. RESULTS: Of the 3396 study participants (mean age 80.6 ± 9.1 years; 57.1% females), 10.8% used trazodone and 8.5% others antidepressants. Individuals treated with trazodone were older, more functionally dependent, and had a higher prevalence of dementia and BPSD than those using other antidepressants or no antidepressant use. Logistic regression analyses found that the presence of BPSD was associated with trazodone use (odds ratio (OR) 28.4, 95% confidence interval (CI) 18-44.7 for the outcome trazodone vs no antidepressants use, among participants without depression; OR 2.17, 95% CI 1.05-4.49 for the outcome trazodone vs no antidepressants use, among participants with depression). A cluster analysis of trazodone use identified three clusters: cluster 1 included mainly women, living at home with assistance, multimorbidity, dementia, BPSD, and depression; cluster 2 included mainly institutionalized women, with disabilities, depression, and dementia; cluster 3 included mostly men, often living at home unassisted, with better mobility performance, fewer chronic diseases, dementia, BPSD, and depression. DISCUSSION: The use of trazodone was highly prevalent in functionally dependent and comorbid older adults admitted to LTCF or living at home. Clinical conditions associated with its prescription included depression as well as BPSD.

Efficacy of COVID-19 control measures on post-vaccination outbreak in Italian Long Term Care Facilities: implications for policies.

Background: Numerous individual and organizational factors can influence the spread of SARS-CoV-2 infection in Long Term Care Facilities (LTCFs). A range of outbreak control measures are still implemented in most facilities involving administrations, staff, residents and their families. This study aims to evaluate which measure could influence the transmission of SARS-CoV-2 infection among residents during the period March 2021-June 2022. Methods: We enrolled 3,272 residents aged ≥60 years. The outbreak control measures adopted to prevent or manage the infection included entry regulations, contact-regulating procedures, and virological surveillance of residents and staff. The association between LTCFs' and participants' characteristics with new cases of COVID-19 infections was analyzed using multilevel logistic regression models. Results: In 33.8% of the facilities 261 cases of SARS-CoV-2 infection were reported. Among participant characteristics, gender and age were not associated with SARS-CoV-2 infection, while having received the vaccine booster dose was protective against infection [Odds Ratio (OR) = 0.34, 95% Confidence Interval (CI) 0.12-0.99, p = 0.048]. In addition, the implementation of protected areas for family visits was associated with a significant reduction of the probability of infections (OR = 0.18, 95% CI 0.03-0.98, p = 0.047). Overall, about 66% of the variability in the probability of SARS-CoV-2 infection during the observational period may be due to facility structure characteristics and 34% to the participant characteristics. Conclusions: These data showed that vaccination booster doses and family visit restriction-control are still needed to make the LTCFs safer against SARS-CoV-2 infection.

Fosinopril and zofenopril, two angiotensin-converting enzyme (ACE) inhibitors, potentiate the anticonvulsant activity of antiepileptic drugs against audiogenic seizures in DBA/2 mice.

The renin-angiotensin system (RAS) exists in the brain and it may be involved in pathogenesis of neurological and psychiatric disorders including seizures. The aim of the present research was to evaluate the effects of some angiotensin-converting enzyme inhibitors (ACEi; captopril, enalapril, fosinopril and zofenopril), commonly used as antihypertensive agents, in the DBA/2 mice animal model of generalized tonic-clonic seizures. Furthermore, the co-administration of these compounds with some antiepileptic drugs (AEDs; carbamazepine, diazepam, felbamate, gabapentin, lamotrigine, phenobarbital, phenytoin, topiramate and valproate) was studied in order to identify possible positive interactions in the same model. All ACEi were able to decrease the severity of audiogenic seizures with the exception of enalapril up to the dose of 100mg/kg, the rank order of activity was as follows: fosinopril>zofenopril>captopril. The co-administration of ineffective doses of all ACE inhibitors with AEDs, generally increased the potency of the latter. Fosinopril was the most active in potentiating the activity of AEDs and the combination of ACEi with lamotrigine and valproate was the most favorable, whereas, the co-administrations with diazepam and phenobarbital seemed to be neutral. The increase in potency was generally associated with an enhancement of motor impairment, however, the therapeutic index of combined treatment of AEDs with ACEi was predominantly more favorable than control. ACEi administration did not influence plasma and brain concentrations of the AEDs studied excluding pharmacokinetic interactions and concluding that it is of pharmacodynamic nature. In conclusion, fosinopril, zofenopril, enalapril and captopril showed an additive anticonvulsant effect when co-administered with some AEDs, most notably carbamazepine, felbamate, lamotrigine, topiramate and valproate, implicating a possible therapeutic relevance of such drug combinations.

An Overview of Combination Treatment with Citicoline in Dementia.

INTRODUCTION: The present article reports an overview of the studies about combination treatment with citicoline of Alzheimer's (AD) and mixed dementia (MD). METHODS: A Medline search was carried out by using the keywords Alzheimer's dementia, mixed dementia, older people, treatment with citicoline, memantine, and acetylcholinesterase inhibitors (AchEIs). RESULTS: Six studies were found to match the combination treatment of citicoline with AcheIs and/or memantine. The CITIRIVAD and CITICHOLINAGE studies were the first to report the potential benefits of adding citicoline to acetylcholinesterase inhibitors (AchEIs). Then, we added citicoline to memantine in the CITIMEM study, and finally, we demonstrated benefits in terms of delay in cognitive worsening with the triple therapy (citicoline + AchEIs + memantine). Other authors also reinforced our hypothesis through two further studies. CONCLUSION: Open, prospective studies are advised to confirm the utility of combination therapy with citicoline for the treatment of AD and MD.
