Memory performances and personality traits in mothers of children with obstructive sleep apnea syndrome
Background: Chronic diseases in pediatric age have been identified as stressful risk factors
for parents. Studies on caregivers have documented the impact of chronic parenting stress on
emotion and cognition.
Aim: To investigate the differences between a group of mothers of children affected by
obstructive sleep apnea syndrome (OSAS) for at least 4 years and a group of mothers of
typically developing children (TDC) in relation to parental stress, self-esteem, locus of
control, and memory performances.
Methods: A group of 86 mothers (mean age 35.6±4.9, ranged between 32 and 41 years) of
children with OSAS diagnosis, and a group of 52 mothers of TDC (mean age 35.9±4.2,
ranged between 32 and 41 years) participated in the study. All participants were administered
stress level, global self-esteem, internal/external locus of control scales, and memory
assessment.
Results: Mothers of OSAS children, compared to mothers of TDC, had a significantly
higher level of stress, lower self-esteem, more external locus of control and poorer memory
performance.
Conclusions: The child respiratory disease, with its sudden and unpredictable features,
appeared as a significant source of stress for the mother. Such stress condition may have an
impact on mothers’ personality traits (self-esteem, locus of control) and on their memory
performances. The data have suggested a need for psychological support programs for
mothers to better manage stress associated with children’s respiratory disease
The Effect of the Association between Donepezil and Choline Alphoscerate on Behavioral Disturbances in Alzheimer's Disease: Interim Results of the ASCOMALVA Trial
BACKGROUND:
Behavioral and psychological symptoms of dementia (BPSD) are a group of psychological reactions, psychiatric symptoms, and behaviors commonly found in Alzheimer's disease (AD). Four clusters of BPSD have been described: mood disorders (depression, anxiety, and apathy), psychotic symptoms (delusions and hallucinations), aberrant motor behaviors (pacing, wandering, and other purposeless behaviors), and inappropriate behaviors (agitation, disinhibition, and euphoria). Most of them are attributed to acetylcholine deficiency.
OBJECTIVE:
To evaluate if a higher amount of acetylcholine obtained by associating donepezil and choline alphoscerate might have a favorable effect on BPSD.
METHODS:
BPSD were measured at baseline and after 24 months in 113 mild/moderate AD patients, included in the double-blind randomized trial ASCOMALVA, by the Neuropsychiatric Inventory (NPI). Two matched groups were compared: group A treated with donepezil (10 mg/day) plus choline alphoscerate (1200 mg/day), and group B treated with donepezil (10 mg/day) plus placebo.
RESULTS:
Data of NPI revealed a significant decrease of BPSD severity and distress of the caregiver in patients of group A compared with group B. Mood disorders (depression, anxiety and apathy) were significantly decreased in subjects treated with donepezil and choline alphoscerate, while their severity and frequency was increased in the other group.
CONCLUSIONS:
Patients treated with donepezil plus choline alphoscerate showed a lower level of behavioral disturbances than subjects treated with donepezil only, suggesting that the association can have beneficial effect
Assessment of neuroactive steroids in cerebrospinal fluid comparing acute relapse and stable disease in relapsing-remitting multiple sclerosis
Previous studies have reported an involvement of neuroactive steroids as neuroprotective and anti-inflammatory agents in neurological disorders such as multiple sclerosis (MS); an analysis of their profile during a specific clinical phase of MS is largely unknown. The pregnenolone (PREG), dehydroepiandrosterone (DHEA), and allopregnanolone (ALLO) profile was evaluated in cerebrospinal fluid (CSF) in relapsing-remitting multiple sclerosis (RR-MS) patients as well as those in patients affected by non-inflammatory neurological (control group I) and without neurological disorders (control group II). An increase of PREG and DHEA values was shown in CSF of male and female RR-MS patients compared to those observed in both control groups. The ALLO values were significantly lower in female RR-MS patients than those found in male RR-MS patients and in female without neurological disorder. During the clinical relapse, we observed female RR-MS patients showing significantly increased PREG values compared to female RR-MS patients in stable phase, while their ALLO values showed a significant decrease compared to male RR-MS patients of the same group. Male RR-MS patients with gadolinium-enhanced lesions showed PREG and DHEA values higher than those found in female RR-MS patients with gadolinium-enhanced lesions. Similary, male RR-MS patients with gadolinium-enhanced lesions showed PREG and DHEA values higher than male without gadolinium-enhanced lesions. Female RR-MS patients with gadolinium-enhanced lesions showed DHEA values higher than those found in female RR-MS patients with gadolinium-enhanced lesions. Male and female RR-MS patients with gadolinium-enhanced lesions showed ALLO values higher than those found in respective gender groups without gadolinium-enhanced lesions. ALLO values were lower in male than in female RR-MS patients without gadolinium-enhanced lesions. Considering the pharmacological properties of neuroactive steroids and the observation that neurological disorders influence their concentrations, these endogenous compounds may have an important role as prognostic factors of the disease and used as markers of MS activity such as relapses
Characterisation of the immune-related transcriptome in resected biliary tract cancers
Although biliary tract cancers (BTCs) are known to have an inflammatory component, a detailed characterisation of immune-related transcripts has never been performed. In these studies, nCounter PanCancer Immune Profiling Panel was used to assess the expression of 770 immune-related transcripts in the tumour tissues (TTs) and matched adjacent tissues (ATs) of resected BTCs. Cox regression analysis and Kaplan-Meier methods were used to correlate findings with relapse-free survival (RFS). The first analysis in the TT and AT of an exploratory set (n = 22) showed deregulation of 39 transcripts associated with T-cell activation. Risk of recurrence was associated with a greater number of genes deregulated in AT in comparison to TT. Analysis in the whole set (n = 53) showed a correlation between AT cytotoxic T-lymphocyte antigen-4 (CTLA4) expression and RFS, which maintained statistical significance at multivariate analysis. CTLA4 expression correlated with forkhead box P3 (FOXP3) expression, suggesting enrichment in T regulatory cells. CTLA4 is known to act by binding to the cluster of differentiation 80 (CD80). No association was seen between AT CD80 expression and RFS. However, CD80 expression differentiated prognosis in patients who received adjuvant chemotherapy. We showed that the immunomodulatory transcriptome is deregulated in resected BTCs. Our study includes a small number of patients and does not enable to draw definitive conclusions; however, it provides useful insights into potential transcripts that may deserve further investigation in larger cohorts of patients.

SLAM map application for tracking lights on car dashboards
Recent studies conducted by some insurance companies highlighted that the most part of drivers do not know the meaning of the dashboard lights. This leads drivers to be dangerous for others and themselves. Hence, the need to provide drivers with tools that support them to always be aware of the state of their cars. This paper proposes a system for mobile devices that uses augmented reality to be able to give information on a particular dashboard lights. The system is implemented by combining the use of Simultaneous Localization and Mapping (SLAM) maps with central moment computation widely used in computer vision. Preliminary research results show that the proposed system achieves its goal enables a a real-time visual feedback
Psychological stress in seafarers: a review
Background: Seafaring is a particular profession, in which workers are usually exposed to several stressors
that are related to the different duties on board ships. This paper has reviewed the main publications
on different factors affecting seafarers with the purpose of identifying specific stress factors related to
a particular duty on board.
Materials and methods: A literature search was conducted using the online databases PubMed and
OvidSP. A survey on health, stress, and fatigue of Australian Seafarers published by the Australian Maritime
Safety Authority (AMSA) fulfilling the selection criteria was also examined. This publication provided
relevant data obtained from a large sample of seafarers.
Results: Our analysis confirmed that seafaring is associated with mental, psychosocial, and physical stressors.
The most important factors were separation from family, loneliness on board, fatigue, multi-nationality,
limited recreation activity, and sleep deprivation. The AMSA report gave a more detailed analysis on
lifestyle and relevant factors inducing psychological distress. Stressors affecting seafarers working in the
engine room were different from those involving the deck crew. Sleep quality and duration were reported to
be poor mainly in pilots, whereas deck crew tended to be less adherent to physical exercise and healthy
lifestyle recommendations.
Conclusions: Seafaring is still associated with relevant mental health risks. Information on known stress
factors on board should be provided to seafarers to help them in lowering stress perception. Strategies for
coping with “inevitable” stress conditions should also be investigated and developed. Strategies to decrease
risks of stress should be directed to the different categories of seafarers, and the results of specific
interventions should be evaluated
Tele-neuropsychological assessment of Alzheimer’s disease
Background: Because of the new pandemic caused by the novel coronavirus disease (COVID-19), the demand for telemedicine and telemonitoring solutions has been exponentially raised. Because of its special advantage to treat patients in an emergency without physical presence at a hospital via video conferencing, telemedicine has been used to overcome distance barriers and to improve access to special domains like neurology. In these pandemic times, telemedicine has been also employed as a support for the diagnosis and treatment of adult-onset dementia disorders including Alzheimer's disease.
Objective: In this study, we carried out a systematic literature analysis to clarify if the neuropsychological tests traditionally employed in face-to-face (FTF) contexts are reliable via telemedicine.
Methods: A systematic literature search for the past 20 years (2001-2020) was carried out through the medical databases PubMed (Medline) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). The quality assessment was conducted by adopting the Newcastle Ottawa Scale (NOS) and only studies with a NOS ≥ 7 were included in this review.
Results: The Mini-Mental State Examination (MMSE) results do not differ when tests are administered in the traditional FTF modality or by videoconference, and only negligible minor changes in the scoring system were noticeable. Other neuropsychological tests used to support the diagnosis of AD and dementia such as the Token Test, the Comprehension of Words and Phrases (ACWP), the Controlled Oral Word Association Test showed high reliability between the two modalities considered. No differences in the reliability concerning the living setting or education of the subjects were reported.
Conclusions: The MMSE, which is the main screening test for dementia, can be administered via telemedicine with minor adaptation in the scoring system. Telemedicine use for other neuropsychological tests also resulted in general reliability and enough accuracy. Cognitive assessment by videoconference is accepted and appreciated and therefore can be used for dementia diagnosis in case of difficulties to performing FTF assessments. This approach can be useful given a personalized medicine approach for the treatment of adult-onset dementia disorders
Hyperspectral imaging to oversee the status of baby leaf vegetable crops: the Agrofiliere Project results
This communication reports a compendium of vegetation indices and hyperspectral band ranges relevant for monitoring the main cryptogamic diseases of wild rocket based on an overview of the recently published papers on the results of the AGROFILIERE project, aimed at studying highly integrated systems for supporting the management of baby leaf vegetable crops. In detail, the phytosanitary framework of wild rocket includes some disease taken as reference for characterizing the hyperspectral response in the reviewed studies, such as downy and powdery mildews, parenchymatic soil-borne diseases, tracheofusariosis and their exception respect to water stress. Thirteen major literature vegetable indices were selected among those that proved capable of discriminating plant health status from disease and some early stages of plant interaction with a pathogen. On the other hand, a few studies have helped to highlight the spectral ranges relevant to a specific disease in wild rocket through the application of machine learning models on hyperspectral data. This overall presentation contributes useful hyperspectral information on the whole available disease frame of wild rocket, with a view to building non-invasive and contactless digital diagnostic tools for disease detection in baby leaf vegetable cropping systems to support their control
Childhood Absence Epilepsy
Childhood absence epilepsy (CAE) is a common epilepsy syndrome characterized by absence seizures aecting young children and representing 18% of all diagnosed cases of epilepsy in school-age children. Absence seizures are classically very frequent during the day and each seizure lasts a short time, from about 10 to 20 seconds, it ends abruptly, and awareness and responsiveness are severely impaired. The typical EEG pattern in CAE is a bilateral, synchronous, and symmetrical discharge of complex spike-wave rhythms at 3 Hz (range of 2.5–4 Hz), with sudden onset and termination. CAE is genetically determined, the mode of inheritance and genes involved remain not fully clarified but the final outcome is the dysregulation of cortico-thalamic-cortical circuit that plays a crucial role in the pathophysiology of absence seizures. CAE may have an impact on patients’ lives in terms of negative consequences in neurocognitive and neuropsychological aspects that should always be considered during a global evaluation of a child with epilepsy
Evaluation of neurocognitive abilities in children affected by obstructive sleep apnea syndrome before and after adenotonsillectomy
Obstructive sleep apnoea syndrome (OSAS) is the most severe form of sleep-related disordered breathing (SRDB) and is characterised by snoring, apnoeas, and/or hypopnoeas associated to hypoxia, hypercarbia, or repeated arousals from sleep. OSAS has three major categories of morbidities: neurobehavioural, cardiovascular and somatic growth failure. The gold standard for objective diagnosis of obstructive-SRDB severity is polysomnography (PSG). The indication for surgical treatment in children is moderate-severe OSAS (AHI, apnoea hypopnoea index > 5/h) and in mild OSAS (AHI 2-5/h) with complications or morbidity. The entire spectrum of PSG-defined SRDB (ranging from Primary Snoring to severe OSAS) may correlate with behavioural, attentional and executive function deficits relating to hypoxia and sleep disruption: in some cases, these alterations may mimic attention deficit hyperactivity disorder (ADHD). The aim of this research was to evaluate visuoperceptual and constructional abilities, paediatric sleep questionnaire and polysomnographic scores before and 6 months after adenotonsillectomy with objective and subjective information. We included 59 children who underwent neuropsychiatric and otolaryngologist clinical evaluation and the Beery-Buktenica Developmental Test of Visual-Motor Integration (VMI); children parents were asked to fill in the Paediatric Sleep Questionnaire (PSQ); each child underwent PSG. At 6 months after adenotonsillectomy, all patients were evaluated again. There is a significant difference in PSQ parameters, VMI standard, visual tests scores and PSG parameters before and after adenotonsillectomy in children affected by OSAS. These results showed the achievement of therapeutic benefits with improvement of the quality of life for both children and their parents
