I Parchi Nazionali Italiani: territorio, governance e performatività

L’oggetto di studio di questo lavoro sono i parchi nazionali italiani. L’idea alla base è quella di confutare l’immagine del parco come semplice simbolo di aspetti naturali e paesaggistici da tutelare per dare la dovuta attenzione anche a tutti gli elementi antropici ed artificiali che caratterizzano questi territori. L'obiettivo è da una parte studiare i parchi in quanto soggetto ed oggetto sociale, proponendone una definizione che rimanda ad un ambiente relazionale; il secondo aspetto, invece, è relativo alla ricostruzione e descrizione della governance dei singoli parchi italiani attraverso le tecniche della Social Network Analysis; infine, quello di utilizzare tecniche di analisi multidimensionale per descriverne e misurarne la performatività

Selecting Insulating Materials for Building Envelope: A Life Cycle Approach

This paper aims at assessing the embodied energy and greenhouse gas emissions (GHGs) of two building envelopes, designed for a two floors semi-detached house located in the Central Italy. The analysis is performed by applying the Life Cycle Assessment methodology, following a from cradle-to-gate approach. Fixtures (windows and doors), external and internal opaque walls, roof and floors (including interstorey floors) make the building envelopes. Their stratigraphy allows for achieving the thermal transmittance values established in the Italian Decree on energy performance of buildings. The two examined envelopes differ only for the insulation material: extruded expanded polystyrene (XPS) or cellulose fibers. The results shows that the envelope using cellulose fibers has better performance than that using XPS: it allows for reducing the embodied energy and the GHGs of about 13% and 9.3%, respectively. A dominance analysis allows to identify the envelope components responsible of the higher impacts and the contribution of the insulating material to the impacts. The study is part of the Italian research “Analysis of the energy impacts and greenhouse gas emissions of technologies and components for the energy efficiency of buildings from a life cycle perspective” funded by the Three-year Research Plan within the National Electricity System 2019-2021

The impact of recurrent Covid-19 waves on patients with Functional Movement Disorders: A follow-up study

Background: Functional Movement Disorders (FMDs) might exacerbate in stressful conditions. As the global health emergency due to Covid-19 rise and multiple waves hit the Italian population, the recurrent severe restrictions' periods imposed could represent important triggers and worsen the symptoms of FMDs. Through a follow-up study, we compare results on Motor Symptoms (MS), Non-Motor Symptoms (NMS), and Global Health Status (GHS) of two surveys, one referred to the first Covid-19 wave and the other to the third Covid-19 wave. Methods: 60 FMDs patients responded to an online survey after the first and the third Covid-19 waves in Italy. Questions regarding sociodemographic, clinical and Covid-19 information, MS, NMS, and GHS were collected to assess severity of symptoms and changes in comparison to a period with less severe social restrictions. Results: Patients showed minimal to mild motor symptoms' severity, and substantial stability through time in all collected measures, both for severity and changes of MS, NMS, and GHS in comparison at two time points (p > 0.050). The worsening of pain resulted as predictor factor for the worsening of Motor Symptoms (p = 0.042). Conclusions: Patients did not show a vulnerability due to the recurrent restrictions' periods: MS, NMS and GHS did not vary in comparison to the first wave, confirming the previous results and highlighting the role of the social context in those disorders. Further investigations are required to better disentangle the relationship between stressful events, motor symptoms, and pain

Measurement of corneal thickness using Pentacam HR versus Nidek CEM-530 specular microscopy.

Objective To compare corneal thickness (CT) measurements using the CEM-530 (Nidal, Gamagori, Japan) and Pentacam HR (Oculus, Wetzlar, Germany). Methods The CT of 209 healthy subjects (209 right eyes) aged 24 to 89 years (71.35 ± 10.72 years) was measured at the corneal apex (CA), pupil center (PC), and thinnest point (TP) with the Pentacam HR and at the corneal center with the CEM-530 in random order at the same time of day. Results A good correlation but statistically significant difference was found between the CEM-530 and Pentacam HR measurements at the CA (6.10 ± 8.12 µm, R2 = 0.8947), PC (7.46 ± 8.57 µm, R2 = 0.8826), and TP (12.44 ± 10.04 µm, R2 = 0.8392). Comparison of the two devices produced the following regression formulas: y = 0.8859x + 57.644 for the CA, y = 0.8852x +56.657 for the PC, and y = 0.8557x + 68.148 for the TP, where x is the CT obtained with the CEM-530 and y is that obtained with the Pentacam HR. Conclusions These findings indicate that the CEM-530 produces a thicker corneal measurement than the Pentacam HR. The herein-proposed correcting factors are needed to reliably compare these devices

Synergism between bisphenol a exposure and overweight/obesity in increasing the malignancy risk in a cohort of patients with thyroid nodules

BPA exposure conferred higher risk of thyroid cancer only in case of concomitant overweight/obesity, therefore suggesting a synergistic action between BPA and the excess of adipose tissue in promoting thyroid carcinogenesis

Territorial survey on the interest in sport in the local territory of "Gian Camillo Glorioso" school

The latest survey by the Central Statistical Institute (ISTAT) in 2015 reports in Italy an increase in the number of sports practitioners compared to 2011. They are greater in girls and more distributed on the 4 age groups chosen as a representative sample. The chosen disciplines vary according to age classes and the previous survey, indicating a significant increase in dance for females and fitness for males. This study doesn’t focus on any reasons for the choices, on the related to the study or work activities and the data don’t emerge locally. The aim of the study is to investigate a limited area, an homogeneous sample based on high school students and to investigate possible motivations including the relationship with the study. Data show that more females (63%) than males (37%) replied to the questionnaire and that a third of the students study 3 hours a day. 60% of students practices sport and the most practiced ones are fitness (38%), dance (19%) and football (16%). The lack of time due to the study prevents physical activity for a third of the students, followed by a lack of motivation (30%) and facilities in the area (13%). In conclusion, results suggest that the study circumscribed locally, with a representative sample of the reference population is more reliable and can be used as a basis for any actions to be taken

Voxel-based morphometry and task functional magnetic resonance imaging in essential tremor: evidence for a disrupted brain network

The pathophysiology of essential tremor (ET) is controversial and might be further elucidated by advanced neuroimaging. Focusing on homogenous ET patients diagnosed according to the 2018 consensus criteria, this study aimed to: (1) investigate whether task functional MRI (fMRI) can identify networks of activated and deactivated brain areas, (2) characterize morphometric and functional modulations, relative to healthy controls (HC). Ten ET patients and ten HC underwent fMRI while performing two motor tasks with their upper limb: (1) maintaining a posture (both groups); (2) simulating tremor (HC only). Activations/deactivations were obtained from General Linear Model and compared across groups/tasks. Voxel-based morphometry and linear regressions between clinical and fMRI data were also performed. Few cerebellar clusters of gray matter loss were found in ET. Conversely, widespread fMRI alterations were shown. Tremor in ET (task 1) was associated with extensive deactivations mainly involving the cerebellum, sensory-motor cortex, and basal ganglia compared to both tasks in HC, and was negatively correlated with clinical tremor scales. Homogeneous ET patients demonstrated deactivation patterns during tasks triggering tremor, encompassing a network of cortical and subcortical regions. Our results point towards a marked cerebellar involvement in ET pathophysiology and the presence of an impaired cerebello-thalamo-cortical tremor network

Malaria, HIV and Malnutrition among Internally Displaced People in Mozambique During COVID-19 Pandemic: Results from a Community-Based Intervention

Background: The spread of COVID-19 poses an unprecedented challenge to care delivery in post-disaster and conflict situations. In Mozambique, the 2019 cyclone Idai and the violence by Non-State-Armed-Groups devastated the province of Sofala and Cabo Delgado respectively and led to the displacement of thousands of people living in poor and overcrowded conditions. The pandemic has further aggravated the situation. Doctors with Africa CUAMM (University college for aspiring missionary doctors) implemented surveillance activities in these regions between October 2020 and September 2021. The aim of this study is to give an overview of the prevalence of malaria, malnutrition, COVID-19 related symptoms and access to HIV testing. Methods: Data were collected in targeted internally displaced people (IDP) sites in Sofala and Cabo Delgado province between 31st January and 25th September 2021. The tool used enabled to assess COVID-19 symptoms, risk of HIV infection, malaria cases and malnutrition in children under five. Results: The project reached 93 503 people. During the study period, 13.6% people reported at least one symptom suggestive of COVID-19 infection. Malaria Rapid Diagnostic Tests (RDT) were administered to 86% of the recruited people (n = ?), with a positive diagnosis in the 4.5% of them (n = ?). Among the recruited Internally Displaced Persons (IDP), 23.1% were considered eligible for HIV screening, but only 1.4% were referred for testing. Acute malnutrition was found in 6.3% of children screened and, among these, a higher prevalence of concurrent COVID-19 symptoms was reported. Discussion: Our study highlights the importance of mass clinical screening for COVID-19 infection in this target population to enact prevention behavior, although this may not be enough, due to the pivotal role played by asymptomatic transmissions. Considering the overlap of the symptoms of COVID-19 and malaria, a combined diagnostic algorithm is urgently needed to avoid underdiagnosing malaria. Moreover, the high prevalence of respiratory symptoms in malnourished children confirmed the known correlation between malnutrition and respiratory infection. Finally, access to HIV screening needs to be implemented, given the high prevalence of people with HIV risk factors to avoid diagnostic delay. Conclusions: Population-specific needs make necessary to develop new screening methods that respond to the specific characteristics of the target population

Lopinavir/Ritonavir and Darunavir/Cobicistat in Hospitalized COVID-19 Patients: Findings From the Multicenter Italian CORIST Study

Background: Protease inhibitors have been considered as possible therapeutic agents for COVID-19 patients. Objectives: To describe the association between lopinavir/ritonavir (LPV/r) or darunavir/cobicistat (DRV/c) use and in-hospital mortality in COVID-19 patients. Study Design: Multicenter observational study of COVID-19 patients admitted in 33 Italian hospitals. Medications, preexisting conditions, clinical measures, and outcomes were extracted from medical records. Patients were retrospectively divided in three groups, according to use of LPV/r, DRV/c or none of them. Primary outcome in a time-to event analysis was death. We used Cox proportional-hazards models with inverse probability of treatment weighting by multinomial propensity scores. Results: Out of 3,451 patients, 33.3% LPV/r and 13.9% received DRV/c. Patients receiving LPV/r or DRV/c were more likely younger, men, had higher C-reactive protein levels while less likely had hypertension, cardiovascular, pulmonary or kidney disease. After adjustment for propensity scores, LPV/r use was not associated with mortality (HR = 0.94, 95% CI 0.78 to 1.13), whereas treatment with DRV/c was associated with a higher death risk (HR = 1.89, 1.53 to 2.34, E-value = 2.43). This increased risk was more marked in women, in elderly, in patients with higher severity of COVID-19 and in patients receiving other COVID-19 drugs. Conclusions: In a large cohort of Italian patients hospitalized for COVID-19 in a real-life setting, the use of LPV/r treatment did not change death rate, while DRV/c was associated with increased mortality. Within the limits of an observational study, these data do not support the use of LPV/r or DRV/c in COVID-19 patients
