Clinical Presentation of COVID19 in Dementia Patients
2020
No studies analyzing the role of dementia as a risk factor for mortality in patients affected by COVID-19. We assessed the prevalence, clinical presentation and outcomes of dementia among subjects hospitalized for COVID19 infection.
Retrospective study.
COVID wards in Acute Hospital in Brescia province, Northern Italy.
We used data from 627 subjects admitted to Acute Medical wards with COVID 19 pneumonia.
Clinical records of each patients admitted to the hospital with a diagnosis of COVID19 infection were retrospectively analyzed. Diagnosis of dementia, modalities of onset of the COVID-19 infection, symptoms of presentation at the hospital and outcomes were recorded.
Dementia was diagnosed in 82 patients (13.1%). The mortality rate was 62.2% (51/82) among patients affected by dementia compared to 26.2% (143/545) in subjects without dementia (p<0.001, Chi-Squared test). In a logistic regression model age, and the diagnosis of dementia resulted independently associated with a higher mortality, and patients diagnosed with dementia presented an OR of 1.84 (95% CI: 1.09–3.13, p<0.05). Among patients diagnosed with dementia the most frequent symptoms of onset were delirium, especially in the hypoactive form, and worsening of the functional status.
The diagnosis of dementia, especially in the most advanced stages, represents an important risk factor for mortality in COVID-19 patients. The clinical presentation of COVID-19 in subjects with dementia is atypical, reducing early recognition of symptoms and hospitalization.

Light-curve Recovery with Rubin-LSST. II. Unveiling the Darkness of the Galactic Bulge (VESTALE) with RR Lyrae
2024
This work is part of VESTALE, a project initiated within the Legacy Survey of Space and Time (LSST) Cadence Strategy Optimization Process. Its goal is to explore the potential of Rubin-LSST observations aimed at the Galactic bulge (henceforth just “Bulge”) for studying RR Lyrae (RRL) stars. Observation and analysis of RRL stars in the Bulge are crucial for tracing the old population of the central part of our Galaxy and reconstructing its formation. Based on observations conducted with CTIO/DECam by Saha et al. toward Baade’s window, our simulations demonstrate that early Rubin-LSST observations will enable the recovery of RRL light curves (LCs) at Galactic center distances with sufficient precision. This will allow us to utilize theoretical relations from Marconi et al. to determine their distances and/or metallicity, following the REDIME algorithm introduced in Bono et al. We show how reddening and crowding affect our simulations and highlight the importance of considering these effects when deriving pulsation parameters (luminosity amplitudes, mean magnitudes) based on the LCs, especially if the goal is to explore the opposite side of the Bulge through the observation of its RRL. The simulations discussed in this investigation were conducted to support the Survey Cadence Optimization Committee’s decision to observe this important sky region since it has only recently been decided to include part of the Bulge as a target within the LSST main survey.

PI3K/AKT signaling determines a dynamic switch between distinct KSRP functions favoring skeletal myogenesis
2012
Skeletal myogenesis is orchestrated by distinct regulatory signaling pathways, including PI3K/AKT, that ultimately control muscle gene expression. Recently discovered myogenic micro-RNAs (miRNAs) are deeply implicated in muscle biology. Processing of miRNAs from their primary transcripts is emerging as a major step in the control of miRNA levels and might be well suited to be regulated by extracellular signals. Here we report that the RNA binding protein KSRP is required for the correct processing of primary myogenic miRNAs upon PI3K/AKT activation in myoblasts C2C12 and in the course of injury-induced muscle regeneration, as revealed by Ksrp knock-out mice analysis. PI3K/AKT activation regulates in opposite ways two distinct KSRP functions inhibiting its ability to promote decay of myogenin mRNA and activating its ability to favor maturation of myogenic miRNAs. This dynamic regulatory switch eventually contributes to the activation of the myogenic program.

Mental Health among Geriatric Healthcare Workers in Italy during the COVID-19 Pandemic: Results from a National Survey
2023
This study aimed to investigate the psychological impact of the COVID-19 pandemic on healthcare workers (HCWs) in geriatric settings.
Online cross-sectional survey.
394 geriatric HCWs in Italy.
The survey was developed by a multidisciplinary team and disseminated in April 2022 to the members of two geriatric scientific societies (Italian Society of Geriatrics and Gerontology and Italian Association of Psychogeriatrics). The survey examined the experiences related to the COVID-19 pandemic, as well as psychological burden and support. Work-related anxiety and distress related to the pandemic were studied using the SAVE-9 scale (Stress and Anxiety to Viral Epidemics).
Three hundred sixty-four participants (92.4%) changed their job activity during the pandemic and about half (50.9%) failed to cope with this change, 58 (14.7%) had increased work-related anxiety, and 39 (9.9%) work-related stress levels. Three hundred forty (86.3%) participants reported acute stress reaction symptoms, including irritability, depressed mood, headache, anxiety, and insomnia, and 262 (66.5%) required psychological support, mainly from friends/relatives (57.9%) and/or colleagues (32.5%). Furthermore, 342 participants (86.8%) recognized they would benefit from informal and formal psychological support in case of future similar emergencies.
This study highlights the high psychological burden experienced by geriatric HCWs in Italy during the COVID-19 pandemic and emphasizes the need for supportive interventions.

Background
Delirium (acute brain dysfunction) is a potentially life threatening disturbance in brain function that frequently occurs in critically ill patients. While this area of brain dysfunction in critical care is rapidly advancing, striking limitations in use of terminology related to delirium internationally are hindering cross-talk and collaborative research. In the English literature, synonyms of delirium such as the Intensive Care Unit syndrome, acute brain dysfunction, acute brain failure, psychosis, confusion, and encephalopathy are widely used. This often leads to scientific \"confusion\" regarding published data and methodology within studies, which is further exacerbated by organizational, cultural and language barriers.
Objective
We undertook this multinational effort to identify conflicts in terminology and phenomenology of delirium to facilitate communication across medical disciplines and languages.
Methods
The evaluation of the terminology used for acute brain dysfunction was determined conducting communications with 24 authors from academic communities throughout countries/regions that speak the 13 variants of the Romanic languages included into this manuscript.
Results
In the 13 languages utilizing Romanic characters, included in this report, we identified the following terms used to define major types of acute brain dysfunction:
coma
,
delirium
,
delirio
,
delirium tremens
,
délire
,
confusion mentale
,
delir
,
delier
,
Durchgangs-Syndrom
,
acute verwardheid
,
intensiv-psykose
,
IVA
-
psykos
,
IVA
-
syndrom
,
akutt konfusion
/
forvirring
. Interestingly two terms are very consistent: 100 % of the selected languages use the term
coma
or
koma
to describe patients unresponsive to verbal and/or physical stimuli, and 100% use
delirium tremens
to define delirium due to alcohol withdrawal. Conversely, only 54% use the term
delirium
to indicate the disorder as defined by the DSM-IV as an acute change in mental status, inattention, disorganized thinking and altered level of consciousness.
Conclusions
Attempts towards standardization in terminology, or at least awareness of differences across languages and specialties, will help cross-talk among clinicians and researchers.

Summary
A score for identifying post-hip-fracture surgery patients at various levels (high, medium, and low) of risk for unsuccessful recovery of pre-fracture walking ability was developed. Three hundred ninety-eight HF patients were enrolled in the study. The score significantly and independently predicted failure to walk independently at discharge, failure to walk independently after 12 months, and death after 12 months. The score may be useful for clinicians and healthcare administrators to target populations for rehabilitative programs.
Introduction
To develop a model predicting at the time that elderly hip-fracture (HF) patients undergo rehabilitation if they will have recovered walking independence at discharge.
Methods
Data from all patients admitted to a Department of Rehabilitation in Italy between January 2001 and June 2008 after HF surgery were used. Variables concerning cognitive, clinical, functional, and social parameters were evaluated. Predominant measures were identified through correspondence analysis, and a variable score was defined. Three risk classes (minimum, moderate, and high) were identified and univariate and multivariate logistic regressions were used to assess the model's predictivity and risk classes for the various outcomes.
Results
Three hundred ninety-eight HF patients were enrolled. The variables selected to construct the score were age, gender, body mass index, number of drugs being taken, the Mini Mental State Examination, the Instrumental Activity of Daily Living, and the pre-fracture Barthel index. According to univariate analysis, the score was not better than the pre-fracture Barthel's index, but, according to multivariate analysis, it was an independent predictor for all the outcomes, while the pre-fracture Barthel index predicted only outcomes at discharge. In particular, the score significantly predicted failure to walk independently at discharge, failure to walk independently after 12 months, and death after 12 months.
Conclusions
A method of identifying post-HF surgery patients at various levels (high-, medium-, and low-) of risk for unsuccessful recovery of pre-fracture walking ability has been designed. The method may be useful for clinicians and healthcare administrators to target populations for rehabilitative programs.

There are no studies that have identified the ability to recognize and manage delirium among Italian health providers caring for patients at risk. Therefore, the Italian Association of Psychogeriatrics (AIP) conducted a multicenter survey among doctors, nurses, psychologists and physiotherapists to assess their competence regarding the theme of delirium and its management in the everyday clinical practice.
The survey period was 1st June 2013 to 30th November 2013. The invitation to participate was sent via email, with publication on the AIP website. The survey included 14 questions and two case vignettes.
A total of 648/1,500 responses were collected. Most responders were doctors (n = 322/800), followed by nurses (n = 225/500), psychologists (n = 51/100), and physiotherapists (n = 30/100). Generally, doctors and psychologists correctly defined delirium, while nurses and physiotherapists did not. The most frequently used diagnostic tools were the Confusion Assessment Method (CAM) and the Diagnostic and Statistical Manual of Mental Disorders-IV. Delirium intensity was rarely assessed. Hypoactive delirium was generally managed with non-pharmacological approaches, while hyperactive delirium with a combination of non-pharmacological and pharmacological approaches. However, possible causes of delirium were under-assessed by half of doctors and by the majority of other professionals. Nurses, psychologists and physiotherapists did not answer the case vignettes, while doctors identified the correct answer in most cases.
This is the first Italian survey among health providers caring for patients at risk of delirium. This is also the first survey including doctors, nurses, psychologists and physiotherapists. The results emphasize the importance of training to improve knowledge of this relevant unmet medical need.

There are still substantial uncertainties over best practice in delirium care. The European Delirium Association (EDA) conducted a survey of its members and other interested parties on various aspects of delirium care.
The invitation to participate in the online survey was distributed among the EDA membership. The survey covered assessment, treatment of hyperactive and hypoactive delirium, and organizational management.
A total of 200 responses were collected (United Kingdom 28.6%, Netherlands 25.3%, Italy 15%, Switzerland 9.7%, Germany 7.1%, Spain 3.8%, Portugal 2.5%, Ireland 2.5%, Sweden 0.6%, Denmark 0.6%, Austria 0.6%, and others 3.2%). Most of the responders were doctors (80%), working in geriatrics (45%) or internal medicine (14%). Ninety-two per cent of the responders assessed patients for delirium daily. The most commonly used assessment tools were the Confusion Assessment Method (52%) and the Delirium Observation Screening Scale (30%). The first-line choice in the management of hyperactive delirium was a combination of non-pharmacological and pharmacological approaches (61%). Conversely, non-pharmacological management was the first-line choice in hypoactive delirium (67%). Delirium awareness (34%), knowledge (33%), and lack of education (13%) were the most commonly reported barriers to improving the detection of delirium. Interestingly, 63% of the responders referred patients after an episode of delirium to a follow-up clinic.
This is the first systematic survey involving an international group of specialists in delirium. Several areas of lack of consensus were found. These results emphasise the importance of further research to improve care of this major unmet medical need.

Akt2-mediated phosphorylation of Pitx2 controls Ccnd1 mRNA decay during muscle cell differentiation
2010
Paired-like homeodomain 2 (Pitx2), first identified as the gene responsible for the Axenfeld–Rieger syndrome, encodes a protein factor that, controlling cell proliferation in a tissue-specific manner, has a crucial role in morphogenesis. During embryonic development, Pitx2 exerts a role in the expansion of muscle progenitors and is expressed at all stages of myogenic progression. In this study, we show that Pitx2 is phosphorylated by the protein kinase Akt2 and is necessary to ensure proper C2C12 myoblast proliferation and differentiation. Pitx2 associates with a ribonucleoprotein complex that includes the mRNA stabilizing factor HuR and sustains Ccnd1 (also known as Cyclin D1) expression, thereby prolonging its mRNA half-life. When the differentiation program is initiated, phosphorylation by Akt2 impairs the ability of Pitx2 to associate with the Ccnd1 mRNA-stabilizing complex that includes HuR and, as a consequence, Ccnd1 mRNA half-life is shortened. We propose that unphosphorylated Pitx2 is required to favor HuR-mediated Ccnd1 mRNA stabilization, thus sustaining myoblast proliferation. Upon Akt2-phosphorylation, the complex Pitx2/HuR/Ccnd1 mRNA dissociates and Ccnd1 mRNA is destabilized. These events contribute to the switch of C2C12 cells from a proliferating to a differentiating phenotype.
