Use of the PARO robot as a social mediator in a sample of children with neurodevelopmental disorders and typical development

Background

Social robotics is a research field aimed at providing robots with skills related to social behavior and natural human interaction. Many studies have demonstrated the efficacy of these robots as socio-communicative mediators. Others have used them to create a new communication channel and promote social interaction in chil-dren with autism spectrum disorder (ASD). For children with ASD prolonged interpersonal interaction can sometimes generate extreme frustration. They may find it difficult to focus their attention and learn social skills. The robot may therefore become a reliable and more predictable technological intermediary for the child.

Methods

Our study involved the use of the PARO seal robot as a social mediator in groups of children with neurodevelopmental disorders. We aimed to investigate whether the social robot could facilitate relationships with adults in children with neurodevelopmental disorders by comparing their interactions with those of typically developing children.

Results

The results of our research partially confirm what has been reported in the existing literature, while introducing some innovations that could be addressed by future research. The results of the statistical analysis show a positive correlation in the 'interaction' dimension and the presence of the PARO seal in subjects diagnosed with autism without intellectual impairment. These data highlight the PARO robot's ability to facilitate communication and social.

Conclusions

The results of the present study confirm that social robotics can be a valid tool to improve socio-communication skills in clinical samples of children with autism without intellectual impai-rment.

Explorative analysis of gender-specific characteristics in patients with heart failure in an Italian hospital

Sex-related differences have been shown to deeply affect health-related aspects of patients. However, the lack of gender-specific analysis makes it difficult to advance personalized medicine in terms of a gender-based approach. The aim of the present study was to describe gender-specific features of patients diagnosed with heart failure (HF), with a focus on the clinical presentation. Data were collected from a properly designed database and referred to an Italian hospital. Patients aged ≥18 years with a primary or secondary diagnosis of HF between 1 January 2012 and 31 December 2016 were included, and their demographic and clinical characteristics were analyzed according to gender. Of the 719 HF patients included, 317 (44.1%) were male and 402 (55.9%) were female. Women tended to be older compared to men (82.4±8.8 years and 77.1±10.6 years, respectively). As for clinical presentation, 62.1% of female and 38.3% of male patients had preserved ejection fraction, and 56.1% of men and 58.2% of women suffered from atrial fibrillation. The left atrium was partially compromised in 62.4% of male and 63% of female patients, while right atrium dysfunction tended to be more frequent in male patients compared to female patients (29.1% and 25.5%, respectively). In conclusion, gender-specific features of a cohort of HF patients from a clinical setting were accurately described.

Adherence to therapeutic and diagnostic recommendations in patients with femur fracture and at risk of re-fracture or death: results of an analysis of administrative databases

The aim of the present study was to evaluate the application into clinical practice of therapeutic and diagnostic recommendations for the prevention of bone re-fracture in postmenopausal women after an hospitalization for hip fracture in clinical practice and to assess the relationship between the application of diagnostic recommendations and re-fracture or death risk. A retrospective cohort analysis was conducted. All female patients, at least 65 years old, and with an hospitalization with main or secondary diagnosis of hip fracture during the period 1 January 2006 - 31 December 2008, were included. Besides demographic characteristics and comorbidities, drug treatment prescriptions related to bone fracture or supplementary with calcium or vitamin D and prescriptions of recommended laboratory and instrumental diagnostic tests (e.g. spine radiography), were analysed. A total of 5,636 patients were included in the study. The prescription of a drug treatment aimed to reduce the risk of re-fracture was found in 16.3% of patients, among them 76.3% (699 patients) used bisphosphonates only, 17.1% (157 patients) strontium ranelate only and 4.9% (45 patients) used more than one treatment during the observation period. Among the patients who did not receive drug treatment, 17.5% made use of only supplemental calcium and vitamin D. The remaining part of patients (69.1%) received no treatment. The prescription of at least one laboratory test of first and second level was performed, respectively, on 53.7% and 43.1% of included patients, whereas the prescription of at least one instrumental test of first and second level was performed, respectively, on 5.9% and 0.8%. Although it is established that the prescription of the recommended tests and appropriate drug treatment are significantly associated with reduced risk of re-fracture and death, today the application of these recommendations is reduced.

Use of antihypertensive and lipid-lowering drugs: the management of cardiovascular risk in clinical practice

The objective of the study was to analyse the treatment of high blood pressure (BP) and hypercholesterolaemia, as well as the effect of individual or combined antihypertensive-hypocholesterolaemic therapy on BP control and on circulating cholesterol. A retrospective study was performed using clinical data recorded in the general practitioner's database. The sample included all patients, aged > or =18 years, with BP reading or low-density lipoprotein (LDL) cholesterol measurement recorded between January 2003 and December 2004. BP and LDL cholesterol targets were defined using cutoffs based on the guidelines of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC7) and the National Cholesterol Education Program (NCEP/ATPIII). The study included 4764 patients (mean age 67.6+/-11.8 years, 43.5% males). Target BP was achieved in a higher number of patients under combined antihypertensive-hypocholesterolaemic therapy than in those treated only with antihypertensives: 57.0 vs 50.0% in patients with history of cardio/cerebrovascular (CV) hospitalization, 27.0 vs 16.9% in patients with diabetes or chronic renal insufficiency (CRI) and 59.7 vs 49.1% in patients with no CV hospitalization nor diabetes and nor CRI. The LDL cholesterol target was achieved in 61.3% of the subjects: it was independent on the therapy (individual or combined), but related to the degree of cardiovascular risk. Analysing the data contained in the general medicine database made it possible to evaluate the treatment of high BP and hypercholesterolaemia in relation to cardiovascular risk in clinical practice and to establish the need to pay greater attention to achieving the objective set by guidelines.

Time course for the reappearance of vibrissal motor representation following botulinum toxin injection into the vibrissal pad of the adult rat

The present study investigates the time course and pattern of movement representation recovery in the motor cortex during the recovery after a peripheral paralysis. To this end a transitory flaccid paralysis of the vibrissae muscle was induced in adult rats that underwent two unilateral injections of 8 U of botulinum toxin (BTX) into a vibrissal pad, at a duration of 12 days from one another. The compound muscle action potential (MAP) of the vibrissae muscle began to reappear 4 weeks after the first BTX injection. Intracortical microstimulation (ICMS) was used to map rat motor cortices 4, 5, 6, 7 and 8 weeks after the first BTX injection. Findings demonstrated that: (i) contralateral vibrissae movement reappears in the medial part of its normal cortical territory when the MAP is almost 10% of the control value; in the remaining part, ICMS elicits eye, ipsilateral vibrissae, neck and forelimb movements; (ii) the contralateral vibrissae movement reappears in sites where ipsilateral vibrissae and/or neck movement are co-represented; (iii) as MAP recovers, the vibrissae representation expands until it recovers the 90.8% of its territory after 7 weeks, when the MAP was almost 43.4% of the control value; (iv) from 4 to 7 weeks, the ICMS-evoked contralateral vibrissae movement shows a significantly higher electrical threshold vs. the control group; (v) recovery of the baseline excitability uniformly involves the vibrissae representation 1 week later, after its cortical territory has recovered 93.1% of the control value and the MAP has returned to 78.8% of the baseline value.

Cobalt powdersintering industry (stone cutting diamond wheels): a study of environmental-biological monitoring, workplace improvement and health surveillance

This communication deals with an aspect of occupational hygiene in a factory producing granite cutting diamond wheels by sintering, in moulds, of fine cobalt powder. The factory has been studied between 1988 and 1991; the Department of Preventive and Occupational Medicine of the Local Sanitary Unit of Reggio Emilia has followed the evolution of the local exhaust ventilation equipment supplied by the employer in that period. At the same time, the following measurements and observations were carried out: (a) cobalt exposure by personal sampling, (b) airborne cobalt measurements by area sampling, (c) biological monitoring of cobalt in urine, (d) health surveillance.
