    Surveys (2015 – 2018) carried out by the local health agency of Trieste (LHATs) in a collective catering (CC) sample (nurseries, schools, university, hospitals, nursing homes, workplaces), with a total production of 20% of the meals served daily in the area, have shown some critical conditions. In some CC the following has been observed: noncompliance of food supply quality and quantity, loss of up to 80% of antiradicalic power (ARP) and poliphenol content of several vegetable dishes, increase of more than 50% of oxidized compounds in some fish and homogenized meat dishes, as demonstrated by the University of Trieste. This represents a triple burden for the community: consumption of non-protective meals from oxidative stress; fraud of product quality/quantity (equal to 2-4% of contract value); and failure of the challenges of Sustainable Development Goals (SDGs). It is also a serious problem for institutionalized and hospitalized people as, according to the literature, the prevalence of the risk of malnutrition in patients exceeds 50% and 25% respectively. In view of these findings, LHATs has developed recommendations and tools to improve the control capability of organizations that outsource the CC. These recommendations take into consideration: analysis of item costs, merceological food value, working conditions, and integrate the indications of the Ministry of Health for CC that provide: adoption of dietary guidelines, Nutrient Analysis Critical Control Points (NACCP) process and updated food composition. Tools recommended by LHATs permit monitoring and control food supply quality-quantity, NACCP process, ARP and other markers to detect the nutritional value of meals. The key process to developing actions to better apply food and nutrition policies and to contribute to SDGs in strategic local CC is the ability of the public health to analyze its context in a systemic view to innovative provision of improve sustainable healthy protective nutrition for communities

    Background: Alzheimer's disease (AD) has been associated with dysregulation of brain cholesterol trafficking and abnormal production of apolipoprotein E isoform 4 (apoE4). Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a protein present in serum and cerebrospinal fluid (CSF) degrading the low-density lipoprotein receptor (LDLr) and other apoE-binding receptors involved in neuron cholesterol uptake. The role of PCSK9 in AD is controversial. Objective: We compared PCSK9 levels in CSF of AD patients and non-AD controls and looked at correlations with CSF total apoE and apoE4. Methods: CSF from AD (n = 30) and from age and sex-matched non-AD patients (n = 30) was collected by lumbar puncture for routine diagnosis. CSF PCSK9, total apoE, and apoE4 levels were measured by ELISA. AD patients showed the typical CSF neurobiomarker pattern (decreased A beta(42) and increased tau and phospho-tau) and impaired cognitive performances, as indicated by the scores of the Mini-Mental State Examination test. Results: PCSK9 levels in CSF were higher in AD than in non-AD subjects (+1.45 fold; p = 0.0049). CSF total apoE concentrations did not differ between the two groups, while apoE4 levels were higher in AD subjects (+3.34 fold; p = 0.0068). Considering all samples, a significant positive correlation was found between PCSK9 and apoE4 (r = 0.4409; p = 0.0006). PCSK9 levels were higher in APOE epsilon 4 carriers, reaching statistical significance in the AD group (+1.45 fold; p = 0.0454). Conclusion: These results report for the first time an alteration of CSF PCSK9 levels in AD and suggest a pathophysiological link between PCSK9, apoE4, and AD

    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 \ub1 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

    Enhancing cognitive training effects in Alzheimer's disease: rTMS as an add-on treatment

    Get PDF
    The treatment of Alzheimer's disease (AD) in the field of non-pharmacological interventions is a challenging issue, given the limited benefits of the available drugs. Cognitive training (CT) represents a commonly recommended strategy in AD. Recently, repetitive transcranial magnetic stimulation (rTMS) has gained increasing attention as a promising therapeutic tool for the treatment of AD, given its ability of enhancing neuroplasticity. In the present randomized, double-blind, sham-controlled study, we aimed at investigating the add-on effect of a high frequency rTMS protocol applied over the left dorsolateral prefrontal cortex (DLPFC) combined with a face-name associative memory CT in the continuum of AD pathology. Fifty patients from a very early to a moderate phase of dementia were randomly assigned to one of two groups: CT plus real rTMS or CT plus placebo rTMS. The results showed that the improvement in the trained associative memory induced with rTMS was superior to that obtained with CT alone. Interestingly, the extent of the additional improvement was affected by disease severity and levels of education, with less impaired and more educated patients showing a greater benefit. When testing for generalization to non-trained cognitive functions, results indicated that patients in CT-real group showed also a greater improvement in visuospatial reasoning than those in the CT-sham group. Interestingly, this improvement persisted over 12 weeks after treatment beginning. The present study provides important hints on the promising therapeutic use of rTMS in AD

    Non Fluent Variant of Primary Progressive Aphasia Due to the Novel GRN g.9543delA(IVS3-2delA) Mutation

    Mutations in progranulin gene (GRN) are a common cause of autosomal dominant frontotemporal lobar degeneration syndromes and are associated with a wide phenotypic heterogeneity. The majority of genetic defects in GRN consists of loss-of-function mutations, causing haploinsufficiency, and is associated with extremely low plasma progranulin levels. Herein, we describe a patient who developed language dysfunctions and memory disturbances at 63 years of age. Considering the early onset and the positive family history (sister aged 50 with non-fluent/agrammatic variant of primary progressive aphasia, father with behavioral disturbances in his sixties), a genetic analysis was carried out, showing the presence of a novel mutation [g.9543delA (IVS3-2delA)] in a predicted splicing site of GRN. Her progranulin plasma levels were under the reference threshold, as in her sister, thus supporting the causative role of the new variant. The same genetic mutation was confirmed by sequencing in her sister. Results described enlarge current knowledge on genetic causes of the disease and clinical characteristics of carriers
