Parents-children co-regulation as therapeutic variable and target in autism spectrum disorders. From observation of drive to need of cooperative parent-mediated therapy

Abstract

Autism spectrum disorders (ASDs) belong to the category of neurodevelopmental disorders. ASD emerges in early childhood and involves deficits in communication, language, behavioural inflexibility and fixity, and sensorial neurodivergent perception. ASDs have a biological pathogenesis related to genetic and epigenetic factors. Additionally, research has shown that starting from childhood, autistic persons could find emotional regulation challenging during communication with caregivers. The importance of emotional co-regulation has always been under-lined in psychology, starting with Freud who introduced the concept of the Compassionate Other. Emotional difficulties are grasped immediately and almost instinctively by parents, who try to modulate their approach to the child's needs from the very beginning. This paper seeks to highlight the importance of emotional co-regulation as a wake-up call-in developmental trajectories that present peculiarities or anomalies. It also emphasizes the significance of emotional co-regulation as a useful tool for intervening in the dysfun-ctionality of such trajectories. This intervention aims to directly involve parents in treatment, as seen in Cooperative parent-mediated therapy. This approach is crucial for facilitating the evolution of the cognitive framework while utilizing this target. This article aims to review the most recent literature on co-regulation after explaining the theoretical framework that gave rise to this concept. It's now well established the importance of adopting a develop-mental approach that starts from the bodily dimension as the basis for the relationship with caregivers, pairs, and unfamiliar people. It is from this basis that starts the affective, emotional, and cognitive construction of the internal and external world of the child. This scoping review takes into account the most recent evidence on co-regulation and autism, emphasizing the importance of this process in diagnostic and therapeutic settings.

Case Report: A child with NFKB1 haploinsufficiency explaining the linkage between immunodeficiency and short stature

We report the case of a patient with common variable immunodeficiency (CVID) presenting with short stature and treated with recombinant human growth hormone (rhGH). Whole exome sequencing revealed a novel single-nucleotide duplication in the NFKB1 gene (c.904dup, p.Ser302fs), leading to a frameshift and thus causing NFKB1 haploinsufficiency. The variant was considered pathogenic and was later found in the patient's mother, also affected by CVID. This is the first reported case of a patient with CVID due to NFKB1 mutation presenting with short stature. We analyzed the interconnection between NFKB1 and GH - IGF-1 pathways and we hypothesized a common ground for both CVID and short stature in our patient.

Evaluation of circulating microRNA profiles in blood as potential candidate biomarkers in a subacute ruminal acidosis cow model - a pilot study

BACKGROUND

Subacute ruminal acidosis (SARA) is a metabolic disorder often observed in high-yielding dairy cows, that are fed diets high in concentrates. We hypothesized that circulating miRNAs in blood of cows could serve as potential candidate biomarkers to detect animals with metabolic dysbalances such as SARA. MicroRNAs (miRNAs) are a class of small non-coding RNAs, serving as regulators of a plethora of molecular processes. To test our hypothesis, we performed a pilot study with non-lactating Holstein-Friesian cows fed a forage diet (FD; 0% concentrate, n = 4) or a high-grain diet (HG; 65% concentrate, n = 4) to induce SARA. Comprehensive profiling of miRNA expression in plasma and leucocytes were performed by next generation sequencing (NGS). The success of our model to induce SARA was evaluated based on ruminal pH and was evidenced by increased time spent with a pH threshold of 5.8 for an average period of 320 min/d.

RESULTS

A total of 520 and 730 miRNAs were found in plasma and leucocytes, respectively. From these, 498 miRNAs were shared by both plasma and leucocytes, with 22 miRNAs expressed exclusively in plasma and 232 miRNAs expressed exclusively in leucocytes. Differential expression analysis revealed 10 miRNAs that were up-regulated and 2 that were down-regulated in plasma of cows when fed the HG diet. A total of 63 circulating miRNAs were detected exclusively in the plasma of cows with SARA, indicating that these animals exhibited a higher number and diversity of circulating miRNAs. Considering the total read counts of miRNAs expressed when fed the HG diet, differentially expressed miRNAs ( log₂ fold change) and known function, we have identified bta-miR-11982, bta-miR-1388-5p, bta-miR-12034, bta-miR-2285u, and bta-miR-30b-3p as potential candidates for SARA-biomarker in cows by NGS. These were further subjected to validation using small RNA RT-qPCR, confirming the promising role of bta-miR-30b-3p and bta-miR-2285.

CONCLUSION

Our data demonstrate that dietary change impacts the release and expression of miRNAs in systemic circulation, which may modulate post-transcriptional gene expression in cows undergoing SARA. Particularly, bta-miR-30b-3p and bta-miR-2285 might serve as promising candidate biomarker predictive for SARA and should be further validated in larger cohorts.

The Effect of Physical Exercise during COVID-19 Lockdown

The COVID-19 pandemic has exerted an effect on the general population that went over every expectation. To explore the effect of physical exercise (PE) during the national lockdown in Italy, a survey was drawn up and administered to a sample composed of 208 subjects. The questionnaire comprised 81 multiple-choice items, including sociodemographic data, health-related questions, and assessment of physical exercise, satisfaction with life, depression, and personality. The purpose of this study is to explore the role of physical exercise during the outbreak following the present hypothesis: first, if a link exists between the time spent on physical exercise during the lockdown and the perceived health condition, depressive and somatic symptomatology, and life satisfaction; second, to find associations among the SF-12 component summaries and the other psychological outcomes; and finally, to explore how physical and psychological variables are predictive of PCS-12 and MCS-12. The results showed that both vigorous and moderate physical exercise was strongly correlated with psychological variables, with statistically significant negative correlations found between age and physical exercise. Additionally, significant positive correlations were observed between physical exercise and mental health indices, such as MCS-12 and SWLS, whereas negative correlations were found with BDI, PCS-12, and SOM-H. The correlation analysis also revealed that physical and individual mental health summaries were associated with psychological outcomes, with statistically significant negative correlations found between PCS-12 and MCS, PCS-12 and SOM-H, and MCS-12 and BDI scores. Regression analysis showed that physical activities and psychological status both had a direct influence on perceived mental and physical well-being during the lockdown, accounting for 56.7% and 35.5% of the variance, respectively. The p-values for the significant correlations ranged from <0.05 to <0.01. Overall, these findings highlight the importance of physical exercise and psychological well-being in maintaining good health during the pandemic.

Polypharmacy Management in a Gender Perspective: At the Heart of the Problem: Analysis of Major Cardiac Diseases, SARS-CoV-2 Affection and Gender Distribution in a Cohort of Patients in Internal Medicine Ward

BACKGROUND

COVID-19 patients with any pre-existing major cardio-vascular disease (CVD) are at the highest risk of viral infection and of developing severe disease. The pathophysiological mechanism is characterized by the viral link to angiotensin-converting enzyme 2 (ACE2) and the involvement of the endothelial system with the release of cytokines and the inflicting of direct damage to the myocardium, the induction of microthrombosis, and the initiation of alterations in oxygen diffusion. The aim of the study is to analyze the clinical course and outcomes in patients (gender-stratified) with pre-existing major CVD.

METHODS

Out of the 1833 (973 M/860 F) patients admitted to the Internal Medicine COVID-19 Unit of "Castelli Hospital", Lazio, Italy, from 1 January 2021 to 31 December 2021, 600 patients (320 M/280 F) with a mean age of 77 (78.6 M/75.1 F) previously had CVD. Demographic characteristics, length of the stay (LOS) and oxygen therapy were evaluated.

RESULTS

All of the CVD COVID-19 patients underwent non-invasive ventilation (NIV). CVD was linked with increased LOS (21 days F/22 M) compared to no CVD (19 days). In total, 32.7% of total patients had major CVD.

CONCLUSIONS

Timely identification and evaluation of patients with pre-existing major CVD are fundamental for adequate treatment based on gender, severity, state of illness and for risk reduction.

ADRIS: The new open-source accessible driving simulator for training and evaluation of driving abilities

BACKGROUND AND OBJECTIVE

Independent living and transportation are crucial aspects for people living with a disability. After an injury, it is important to assess driving ability, in terms of physical and psychological conditions, and to test the effects of prescribed drugs. Within this framework, driving simulators are suitable tools for training driving skills; however, available tools are expensive or lack appropriate sets of behavioral measures to fully characterize the drivers' ability.

METHODS

This work presents the first step toward the development of ADRIS, a new open-source, accessible, realistic virtual reality simulator for training and testing driving skills of people with sensory-motor disability. This includes a prototype based on an open-source simulator for autonomous driving research (CARLA), with the addition of customized features such as adaptable driving controllers, a virtual reality headset, and the possibility to collect behavioral and physiological data. Also, the new system allows to set different environmental conditions, to include and control the timing of potentially dangerous situations, and to set scenarios with various difficulty levels.

RESULTS

Tests on 17 healthy participants demonstrated that the simulator is well tolerated in terms of discomfort, physical fatigue, and mental effort. Also, the system is easy to use and is capable of providing a realistic driving experience, allowing the extraction of reliable behavioral parameters.

CONCLUSIONS

ADRIS combines a high-fidelity virtual world, with customizable features specifically designed for the training and testing of people living with a disability, thus making it usable in many contexts such as home training, rehabilitation, education, and research.

Case Report: Zellweger Syndrome and Humoral Immunodeficiency: The Relevance of Newborn Screening for Primary Immunodeficiency

BACKGROUND

Zellweger syndrome (ZS) is a congenital autosomal recessive disease within the spectrum of peroxisome biogenesis disorders, characterized by the impairment of peroxisome assembly. The presence of peroxisome enzyme deficiencies leads to complex developmental sequelae, progressive disabilities, and multiorgan damage, due to intracellular accumulation of very-long-chain fatty acids (VLCFAs).

CASE PRESENTATION

We report the case of an infant affected by ZS in which agammaglobulinemia, detected through neonatal screening of congenital immunodeficiencies, appeared as a peculiar trait standing out among all the other classical characteristics of the syndrome. The exome analysis through next-generation sequencing (NGS), which had previously confirmed the diagnostic suspicion of ZS, was repeated, but no mutations causative of inborn error of immunity (humoral defect) were detected.

CONCLUSION

In this case, no genetic variants accountable for the abovementioned agammaglobulinemia were detected. Given that the scientific literature reports the involvement of peroxisomes in the activation of Nuclear Factor κ-light-chain-enhancer of activated B cells (NF-κB) pathway, which is crucial for B-cell survival, with this work, we hypothesize the existence of a link between ZS and humoral immunodeficiencies. Further studies are required to confirm this hypothesis.

Urinary Nickel and Progesterone in Workers Exposed to Urban Pollutants

OBJECTIVE

The aim of this study is to evaluate whether the exposure to a low dose of nickel could determinate a variation in levels of progesterone in outdoor workers.

MATERIALS AND METHODS

Two hundred sixty one subjects were divided by sex, task, age, seniority, and cigarette smoking habit. For each workers was evaluated the dose of blood progesterone and urinary nickel.The statistical analysis was performed.

RESULTS

The Pearson correlation showed a statistically significant correlation between urinary nickel levels and progesterone. The multiple linear regression showed a significant correlation between progesterone and urinary nickel in the total sample and in the subgroups of smokers and workers with tasks of traffic direction.

CONCLUSIONS

The results of our study suggest that occupational exposure to low doses of nickel present in urban pollution may influence to progesterone levels in outdoor workers.

Frontal increase of beta modulation during the practice of a motor task is enhanced by visuomotor learning

Movement is accompanied by beta power changes over frontal and sensorimotor regions: a decrease during movement (event-related desynchronization, ERD), followed by an increase (event-related synchronization, ERS) after the movement end. We previously found that enhancements of beta modulation (from ERD to ERS) during a reaching test (mov) occur over frontal and left sensorimotor regions after practice in a visuo-motor adaptation task (ROT) but not after visual learning practice. Thus, these enhancements may reflect local cumulative effects of motor learning. Here we verified whether they are triggered by the learning component inherent in ROT or simply by motor practice in a reaching task without such learning (MOT). We found that beta modulation during mov increased over frontal and left areas after three-hour practice of either ROT or MOT. However, the frontal increase was greater after ROT, while the increase over the left area was similar after the two tasks. These findings confirm that motor practice leaves local traces in beta power during a subsequent motor test. As they occur after motor tasks with and without learning, these traces likely express the cost of processes necessary for both usage and engagement of long-term potentiation mechanisms necessary for the learning required by ROT.

Burden of COVID-19 on Italian Internal Medicine Wards: Delphi, SWOT, and Performance Analysis after Two Pandemic Waves in the Local Health Authority "Roma 6" Hospital Structures

Background: COVID-19 causes major changes in day-to-day hospital activity due to its epidemiological characteristics and the clinical challenges it poses, especially in internal medicine wards. Therefore, it is necessary to understand and manage all of the implicated factors in order to maintain a high standard of care, even in sub-par circumstances. Methods: This was a three-phase, mixed-design study. Initially, the Delphi method allowed us to analyze the causes of poor outcomes in a cohort of an aggregate of Italian COVID-19 wards via an Ishikawa diagram. Then, for each retrieved item, a score was assigned according to a pros/cons, opportunities/threats system. Scores were also assigned according to potential value/perceived risk. Finally, the performances of MCs (Medicine-COVID-19 wards) and MCFs (Medicine-COVID-19-free: Internal Medicine wards) units were represented via a Barber's nomogram. Results: MCFs hospitalized 790 patients (-23.90% compared to 2019 Internal Medicine admissions). The main risk factors for mortality were patients admitted from local facilities (+7%) and the presence of comorbidities (>3: 100%, ≥5: 24.7%). A total of 197 (25%) patients were treated with non-invasive ventilation (NIV). The most deaths (57.14%) occurred in patients admitted from local facilities. Conclusions: Medicine-COVID-19 wards show higher complexity and demand compared to non-COVID-19 ones and they are comparable to sub-intensive therapy wards. It is necessary to promote the use of NIV in such settings.

Time trends, frequency, characteristics and prognosis of short-duration transient global amnesia

Background and purpose

Transient global amnesia (TGA) is characterized by a sudden onset of anterograde amnesia lasting up to 24 h. One major differential for TGA is transient epileptic amnesia, which typically lasts < 1 h. However, TGA can also be short in duration and little is known about the time trends, characteristics and prognosis of TGA cases lasting < 1 h.

Methods

We compared the clinical features of TGA ascertained in two independent cohort studies in Oxfordshire, UK [Oxford cohort 1977–1987 versus Oxford Vascular Study (OXVASC) 2002–2018] to determine the time trends of clinical features of TGA. Results were validated in another independent contemporary TGA cohort in Italy [Northern Umbria TGA registry (NU) 2002–2018]. We compared the risk factors, clinical features and long‐term prognosis (major cardiovascular events, recurrent TGA and seizure/epilepsy) of patients presenting with episodes lasting < 1 h versus those lasting ≥ 1 h.

Results

Overall, 639 patients with TGA were included (114 Oxford cohort, 100 OXVASC, 425 NU). Compared with the original Oxford cohort, there were more cases with TGA lasting < 1 h in OXVASC [32 (32.0%) vs. 9 (8.8%)] and NU (11.8% vs. 8.8% in Oxford cohort). In both OXVASC and NU, patient age, vascular risk factors and clinical features were largely similar between those with TGA lasting < 1 h versus those lasting ≥ 1 h. Moreover, there was no difference in the long‐term risk of seizure/epilepsy or major cardiovascular events between TGA lasting < 1 h versus TGA lasting ≥ 1 h.

Conclusions

Short‐duration TGA episodes (<1 h) were not uncommon and were more frequent than in earlier studies. The clinical features and long‐term prognosis of short‐duration TGA did not differ from more typical episodes lasting ≥ 1 h.

Subgroup comparison according to clinical phenotype and serostatus in autoimmune encephalitis: a multicenter retrospective study

BACKGROUND AND PURPOSE

Autoimmune encephalitides (AE) include a spectrum of neurological disorders whose diagnosis revolves around the detection of neuronal antibodies (Abs). Consensus-based diagnostic criteria (AE-DC) allow clinic-serological subgrouping of AE, with unclear prognostic implications. The impact of AE-DC on patients' management was studied, focusing on the subgroup of Ab-negative-AE.

METHODS

This was a retrospective multicenter study on patients fulfilling AE-DC. All patients underwent Ab testing with commercial cell-based assays (CBAs) and, when available, in-house assays (immunohistochemistry, live/fixed CBAs, neuronal cultures) that contributed to defining final categories. Patients were classified as Ab-positive-AE [N-methyl-d-aspartate-receptor encephalitis (NMDAR-E), Ab-positive limbic encephalitis (LE), definite-AE] or Ab-negative-AE (Ab-negative-LE, probable-AE, possible-AE).

RESULTS

Commercial CBAs detected neuronal Abs in 70/118 (59.3%) patients. Testing 37/48 Ab-negative cases, in-house assays identified Abs in 11 patients (29.7%). A hundred and eighteen patients fulfilled the AE-DC, 81 (68.6%) with Ab-positive-AE (Ab-positive-LE, 40; NMDAR-E, 32; definite-AE, nine) and 37 (31.4%) with Ab-negative-AE (Ab-negative-LE, 17; probable/possible-AE, 20). Clinical phenotypes were similar in Ab-positive-LE versus Ab-negative-LE. Twenty-four/118 (20.3%) patients had tumors, and 19/118 (16.1%) relapsed, regardless of being Ab-positive or Ab-negative. Ab-positive-AE patients were treated earlier than Ab-negative-AE patients (P = 0.045), responded more frequently to treatments (92.3% vs. 65.6%, P < 0.001) and received second-line therapies more often (33.3% vs. 10.8%, P = 0.01). Delays in first-line therapy initiation were associated with poor response (P = 0.022; odds ratio 1.02; confidence interval 1.00-1.04).

CONCLUSIONS

In-house diagnostics improved Ab detection allowing better patient management but was available in a patient subgroup only, implying possible Ab-positive-AE underestimation. Notwithstanding this limitation, our findings suggest that Ab-negative-AE and Ab-positive-AE patients share similar oncological profiles, warranting appropriate tumor screening. Ab-negative-AE patients risk worse responses due to delayed and less aggressive treatments.

Assessment of Biventricular Function by Three-Dimensional Speckle Tracking Echocardiography in Adolescents and Young Adults with Human Immunodeficiency Virus Infection: A Pilot Study

BACKGROUND

The purpose of the study was to assess biventricular parameters of wall deformation with three-dimensional speckle tracking echocardiography (3DSTE) in adolescents and young adults with human immunodeficiency virus (HIV) infection on antiretroviral therapy in order to detect a possible subclinical myocardial dysfunction.

METHODS

Twenty-one patients aged 12-39 years with HIV, 21 normal controls of the same age and sex, and 21 patients with idiopathic nonischemic dilated cardiomyopathy (DCM) were studied with 3DSTE. All HIV patients were stable in terms of HIV infection, with no history of heart disease or other chronic systemic disease except HIV infection, and were on highly active antiretroviral therapy with good immunological control. Standard echocardiographic measures of left ventricular (LV)-right ventricular (RV) function were assessed. 3D LV global longitudinal strain (GLS), circumferential strain, radial strain, and LV twist were calculated. Global area strain (GAS) was calculated by 3DSTE as percentage variation in surface area defined by the longitudinal and circumferential strain vectors. 3D RV global and free-wall longitudinal strain (FWLS) were obtained.

RESULTS

LV GLS and GAS were lower in HIV patients compared to normal controls (p = 0.002, and p = 0.01, respectively). There were no significant differences in LV ejection fractions between the groups. There was a weak positive correlation between LV GLS and age (r = 0.215, p = 0.034) and a weak negative correlation between LV GLS and nadir-CD4 T-cells count (r = 0.198, p = 0.043). DCM patients had more marked and widespread reduction in LV GLS and GAS compared to controls (p < 0.001), whereas in HIV patients LV strain impairment (p < 0.05) was more localized in basal and apical regions. RV FWLS was significantly reduced in HIV patients when compared with the control group (p = 0.03). No patient had pulmonary systolic pressure higher than 35 mm Hg.

CONCLUSIONS

3DSTE may help to identify HIV patients at high cardiovascular risk allowing early detection of biventricular dysfunction in the presence of normal LV ejection fraction and in the absence of pulmonary hypertension. LV strain impairment in HIV patients is less prominent and widespread compared to DCM patients.

Prevalence of chronic venous pathology in healthcare workers and the role of upright standing

BACKGROUND

Chronic venous disease (CVD) affects around 25% of adult population in developed countries and it often represent a health problem for different kind of workers, in particular for who spend much of the working time in upright standing.

METHODS

The study was carried out on a population of 173 nonmedical workers of a midsize hospital in Italy (91 nurse, 31 support staff workers and 51 employees). The study protocol was taken from a previous study of our group and included a clinical examination and a questionnaire.

RESULTS

From the analysis of data it emerged a particular importance of upright standing as major risk factor for CVD. The prevalence of venous pathology seems to be greater among nurses and auxiliaries than the administrative staff and, as expected, it was significantly higher among female workers than in males.

CONCLUSIONS

The results obtained show that the clinical-diagnostic protocol described can be used by doctors for screening venous pathology at workplaces.

No Correlation between Blood Benzene Levels and Luteinizing Hormone Plasma Values in Outdoor Workers

OBJECTIVE

The purpose of the study is to evaluate whether low-dose exposure to benzene, an environmental pollutant to which male and female traffic policemen are daily exposed to could cause alterations in plasma luteinizing hormone (LH) levels.

METHODS

From an initial sample of 1594 workers, we only selected 95 workers of whom study we knew the values of late-shift benzene and LH hormone. All subjects underwent biological monitoring (final blood benzene evaluation) and luteinizing hormone dosing. Excluding subjects with the main confounding factors, the final sample included 76 workers. The normal distribution of the variables was evaluated using the Kolmogorov - Smirnov test, followed by the logarithmic transformation of the LH and benzene values. The comparison among means was performed by using the t-test for the independent samples. The ANOVA test was performed for variables with more than 2 modes (ages and seniority) and Pearson correlation index between variables in the total sample and after subdivision as to sex, job, sports activity and smoking. The results were considered significant when p values were less than 0.05.

RESULTS/CONCLUSION

The study did not show a correlation between benzene levels and LH plasma levels in outdoor workers.

Characterization of microRNA in the follicular fluid of patients undergoing assisted reproductive technology

Female fertility plays a decisive role in the reproduction of mammals, with related issues that include oocyte or embryo quality, establishment of pregnancy, and the physiology of the tissues that contribute to reproduction and metabolic disorders associated with reproductive failure. Although reproductive failure may be attributed to various factors in different species, female infertility is largely controlled by a number of molecular signals that can be regulated in a cycle- and tissue-dependent manner.

Is primary meningococcal arthritis in children more frequent than we expect? Two pediatric case reports revealed by molecular test

Background

Primary meningococcal arthritis is a rare infectious disease that occurs in less than 3% of meningococcal infections and is characterized by arthritis without meningitis, fever, rash, or hemodynamic instability Barahona [Case Rep Orthop 4696014:2017 ]. There are no validated clinical criteria that can be used for the diagnosis. We present two pediatric cases of atypical presentation of meningococcal disease revealed by molecular tests.

Case presentation

The clinical presentation of the two children (6- and 9-years-old) was characterized by signs of arthritis. By Real Time Polymerase Chain Reaction (RT-PCR), we identified N. meningitidis serogroup Y in the joint fluid in both cases. After specific antimicrobial treatment, the clinical conditions of the two patients quickly improved during hospitalization. Conclusions. We believe that the incidence of meningococcal arthritis could be underestimated in those settings where the use of RT-PCR is limited. Clearer data on the incidence of meningococcal disease would help to design specific treatments and the best possible national vaccine strategies [Fiji Sci Rep 23:39784, 2016, J Infect 67:385-90, 2013].

Bi-Atrial Function before and after Percutaneous Closure of Atrial Septum in Patients with and without Paroxysmal Atrial Fibrillation: A 2-D and 3-D Speckle Tracking Echocardiographic Study

Our aim was to analyze atrial function with 2-D (2-D-STE) and 3-D (3-D-STE) speckle tracking echocardiography in patients with atrial septal devices and paroxysmal atrial fibrillation (PAF). One hundred sixteen patients and a subgroup of 22 patients who developed PAF after device insertion were studied. Left atrial and right atrial peak longitudinal strain and standard deviations of time to peak strain (TPS) were calculated using 2-D-STE. The left atrial/right atrial emptying fraction and expansion index were determined using 3-D-STE. By multivariate analysis, pre-closure 3-D right atrial expansion index, left atrial time to peak strain, and 3-D left atrial expansion index were independently associated with PAF. Compared with the other indices, receiver operating characteristic analysis revealed better diagnostic accuracy for the combination of pre-closure time to peak strain and 3-D expansion index in detecting PAF. Patients with atrial septal devices have pre-existing left and right atrial dilation and dysfunction as assessed by 2-D-STE and 3-D-STE that appear sensitive for the stratification of PAF risk in this population.

Dataset on the use of 3D speckle tracking echocardiography in light-chain amyloidosis

The dataset presented in this article is related to the research article entitled "Biventricular assessment of light-chain amyloidosis using 3D speckle tracking echocardiography: Differentiation from other forms of myocardial hypertrophy" (Vitarelli et al., 2018) [1], which examined the potential utility of left ventricular (LV) and right ventricular (RV) deformation and rotational parameters derived from three-dimensional speckle-tracking echocardiography (3DSTE) to diagnose cardiac amyloidosis(CA) and differentiate this disease from other forms of myocardial hypertrophy. The combined assessment of LV basal longitudinal strain, LV basal rotation and RV basal longitudinal strain had a high discriminative power for detecting CA. The data of this study provides more understanding on the value of LV 3DSTE deformation parameters as well as RV parameters in this particular cardiomyopathy.

Wounds Difficult to Heal: An Effective Treatment Strategy

OBJECTIVE

Treatment of wounds difficult to heal concerns 50% of the elderly population in Italy and is therefore a relevant social burden. The present study shows how the treatment with autologous leuco-platelets reduces the healing time of wounds improving the functional recovery.

PATIENTS AND METHODS

Patients (n=100) with ulcers of the legs were divided in two groups: 1) 50 patients treated with conventional therapies; 2) 50 patients treated with autologous leuco-platelet concentrate (LPC) and hyaluronic acid (HIAFF, Hyalofill-F® ) as a scaffold.

RESULTS

After 2 months, a 49% reduction in wound area was observed in the second group and in about 65% wound reduction was achieved in 15 days (4 LPC dressings). In contrast, patients treated by conventional therapies, showed a longer healing time and a greater percentage of failures. Morphometric analysis of biopsy samples obtained from the edge as well as from the bottom of the lesions obtained from the LPC group, detected an abundant presence of neoformed capillaries, characterized by a cubic, "reactive endothelium", close to the site of LPC infiltration.

CONCLUSION

These results suggest that healing was promoted not only by limiting bacterial infections but also by the release of chemotactic and proangiogenic factors from leukocytes and platelets, improving the neoformation of capillaries.

Distortion-product otoacoustic emissions in workers exposed to urban stressors

The study aimed to compare the distortion-product otoacoustic emissions (DPOAEs) with the pure-tone audiometry and to analyze the changes in participants exposed to noise. The results show a prevalence of participants with impaired DPOAEs higher than the prevalence of participants with impaired audiometries in the total sample, in men, and in outdoor workers and a prevalence of impaired DPOAEs and of impaired audiometries in men higher than in women and in outdoor workers higher than in indoor workers. The comparison of mean values between outdoor and indoor workers shows a significant difference only on some frequencies, in the DP-gram. The results suggest a higher effectiveness of DPOAEs compared with the pure-tone audiometry in identifying the presence of any damage in individuals exposed to noise at an early stage.

Quality of Life in Dementia Sufferers: The Role of Diet and Exercise

Background:

Among the myriad of factors modulating quality of life assessments estimated in patients presenting a variety of cognitive impairments, the distinctive and critical influence of diet and exercise cannot be overestimated.

Objective:

The objective of this study was to review the evidence to confirm the association between these health-endowering agents and cognitive performance in People With Dementia as well as providing a correlation between Mini Mental State Examination scores and available anthropometric data.

Methods:

The authors tested the hypothesized correlation on a sample of subjects with instrumentally confirmed cognitive impairment using parameters as Body Mass Index and calf circumference.

Results:

The results confirm the hypothesis and suggesting the possible use of anthropometric data in the process of objective evaluation of the patient with cognitive impairment that could also be used for forensic medicine.

Modulation of Inflammation as a Way of Delaying Alzheimer's Disease Progression: The Diet's Role

Background:

Most of the recent reports suggest that inflammatory mediators play a central role in the etiopathogenesis of Alzheimer's disease (AD) and that the conditions leading to a chronic low-grade inflammation, such as stress, depression, obesity and metabolic syndrome, increase the odds of developing Mild Cognitive Impairment (MCI) and AD. Microglia cells are the main actors in the AD process: stimuli from the microenvironment may induce microglia cells to switch to a classically activated inflammatory phenotype M1, or, on the contrary to an alternatively activated M2 phenotype characterized by the secretion of different types of cytokines. Many attempts are currently being made in order to delay the progression of AD by reducing inflammatory mechanisms underlying the disease. Several studies support a relationship among neuroinflammation and nutrients, foods or dietary patterns, taking into account the synergistic or antagonistic biochemical interactions among nutrients as well as the different food sources of the same nutrient. Natural antioxidant and anti-inflammatory compounds found in plant foods, such as fruits, particularly berries (such as strawberry, blueberry, blackcurrant, blackberry, blueberry and mulberry) have been shown to exert neuroprotective activity. It is still unclear whether the dietary bioactive compounds enter the Blood Brain Barrier (BBB) playing a direct antiinflammatory or pro-inflammatory effect on microglia and/or other Central Nervous System (CNS) cells. Another hypothesis is that they may trigger a peripheral reaction that induce indirectly a CNS' response. The subsequent synthesis of cytokines may drive microglia polarization by different ways. So, via an indirect route microglia detects and responds to immune-to-brain signaling.

Conclusion:

This review summarizes current evidence about the potential mechanisms of the interaction among diet, neuroinflammation and AD.

Early Diagnosis of Cardiovascular Diseases in Workers: Role of Standard and Advanced Echocardiography

Cardiovascular disease (CVD) still remains the main cause of morbidity and mortality and consequently early diagnosis is of paramount importance. Working conditions can be regarded as an additional risk factor for CVD. Since different aspects of the job may affect vascular health differently, it is important to consider occupation from multiple perspectives to better assess occupational impacts on health. Standard echocardiography has several targets in the cardiac population, as the assessment of myocardial performance, valvular and/or congenital heart disease, and hemodynamics. Three-dimensional echocardiography gained attention recently as a viable clinical tool in assessing left ventricular (LV) and right ventricular (RV) function, volume, and shape. Two-dimensional (2DSTE) and, more recently, three-dimensional speckle tracking echocardiography (3DSTE) have also emerged as methods for detection of global and regional myocardial dysfunction in various cardiovascular diseases and applied to the diagnosis of subtle LV and RV dysfunction. Although these novel echocardiographic imaging modalities have advanced our understanding of LV and RV mechanics, overlapping patterns often show challenges that limit their clinical utility. This review will describe the current state of standard and advanced echocardiography in early detection (secondary prevention) of CVD and address future directions for this potentially important diagnostic strategy.

Work related stress and blood glucose levels

AIM

The aim of the study is to evaluate work-related subjective stress in a group of workers on a major Italian company in the field of healthcare through the administration of a valid "questionnaire-tool indicator" (HSE Indicator Tool), and to analyze any correlation between stress levels taken from questionnaire scores and blood glucose values.

MATERIAL AND METHODS

We studied a final sample consisting of 241 subjects with different tasks. The HSE questionnaire - made up of 35 items (divided into 7 organizational dimensions) with 5 possible answers - has been distributed to all the subjects in occasion of the health surveillance examinations provided by law. The questionnaire was then analyzed using its specific software to process the results related to the 7 dimensions. These results were compared using the Pearson correlation and multiple linear regression with the blood glucose values obtained from each subject.

RESULTS

From the analysis of the data the following areas resulted critical, in other words linked to an intermediate (yellow area) or high (red area) condition of stress: sustain from managers, sustain from colleagues, quality of relationships and professional changes. A significant positive correlation (p <0.05) between the mean values of all critical areas and the concentrations of glucose values have been highlighted with the correlation index of Pearson. Multiple linear regression confirmed these findings, showing that the critical dimensions resulting from the questionnaire were the significant variables that can increase the levels of blood glucose.

CONCLUSION

The preliminary results indicate that perceived work stress can be statistically associated with increased levels of blood glucose.

Correlation between benzene and testosterone in workers exposed to urban pollution

AIM

Many studies have examined the effects of benzene on testosterone. The purpose of this study was to evaluate the possible correlation between the blood levels of benzene and the levels of testosterone.

MATERIALS AND METHODS

The study involved a group of 148 subjects. For every worker have been made out a blood sample for the evaluation of benzene and testosterone levels and an urine analysis for the evaluation of the levels of trans, trans-muconic acid and S-phenylmercapturic acid. We estimated the Pearson correlation coefficient between the variables in the sample and the urinary metabolites, age, length of service, gender, BMI. For the analysis of the major confounding factors it was performed a multiple linear regression.

RESULTS

The Pearson correlation coefficiet showed: 1. a significant inverse correlation between the S-phenyl mercapturic acid and free testosterone; 2. a significant direct correlation between trans-trans muconic acid and BMI. After dividing the sample according to the median of blood benzene (161.0 ng / L), Pearson correlation coefficient showed a significant inverse correlation between the S-phenyl mercapturic acid and free testosterone in the group with values below this median.

CONCLUSIONS

Our results, to be considered preliminary, suggest that occupational exposure to low levels of benzene, present in urban pollution, affect the blood levels of testosterone. These results need to be confirmed in future studies, with the eventual possibility of including more specific fertility tests.

Blood pressure in indoor and outdoor workers

INTRODUCTION

The aim of our study is to evaluate the changes in systolic and diastolic blood pressure in two occupational categories: outdoor workers (traffic policemen and environment technicians) and indoor workers.

MATERIALS AND METHODS

The study was conducted comparing the results obtained from three samples of male workers: 175 outdoor traffic policemen, 175 outdoor environment technicians and 175 indoor workers. The outdoor and indoor groups were made comparable by age, length of service, body mass index, alcohol consumption, smoking status.

RESULTS

The mean values of systolic and diastolic blood pressure were found higher in traffic policemen and technicians than in indoor workers, as well as higher values of systolic blood pressure in traffic policemen than in technicians.

CONCLUSIONS

The results suggest that outdoor working affects the blood pressure, contributing to an increased cardiovascular risk.

Work- related Stress, over-nutrition and cognitive disability

Work-related stress may exert a negative impact on a variety of physical and psychological attributes relating to the health of employees and work organizations. Several studies conducted in Italy have shown that workers and employees who express less satisfaction show increased symptoms of obesity and cognitive disability. The latest evidence underlines the pathogenic relationship between stress and neurological disease through inflammatory neuro- immune activation. The aim of this review was to describe the relationship between workplace stress and adverse changes in lifestyle that develop into obesity, neuroinflammation and cognitive dysfunction. The molecular mechanisms involved and guidelines for the prevention of these trends are discussed briefly.

Hepatotoxicity associated to synthetic cannabinoids use

Synthetic cannabinoids (SCs) are psychotropic compounds, chemically created in laboratory to mimic cannabinergic brain activity of delta-9 tetrahydrocannabinol. The consumption of these compounds for recreational purposes can lead to a variety of adverse effects on health including overdose and deaths. Increasingly popular as substances of abuse since the 2000s, SCs were produced initially to bind and study cannabinoid receptors (they also can be called synthetic cannabimimetics) failing in eliminating the psychoactive effects. Currently, SCs are misused by students and young adults as "natural products" because of their herbal aspect. Actually, these apparently innocuous recreational substances hide toxic effects to health. Reported side effects are cardiovascular, gastrointestinal, neurological, renal, metabolic, ophthalmologic, pulmonary and psychoactive including dependence and withdrawal. A few cases of SCs ingestion have also been associated with liver failure. We herein review the recent literature on the SCs toxicity with particular attention to liver damage aspects.

Cognitive disability in alzheimer's disease and its management

Cognitive disability linked to neurodegenerative diseases and in particular to Alzheimer's disease, remains an increasing cause for concern through a dramatic prevalence increment and associated socio-economic burdens. Initially Alzheimer's disease develops asymptomatically with primary clinical signs, such as memory impairment, decline of spatial and perceptual abilities, occurring at a later stage. This delay implies the possibility of promoting early interventions during the pre-symptomatic stage of the disease. Different strategies have been applied in order to prevent/delay onset of Alzheimer's disease or at least to improve quality of life and health conditions of Alzheimer's disease patients and their caregivers, especially in the absence of current viable therapies. Multidomain interventions, aimed at affecting several risk factors simultaneously, offer a versatility that may attain improved outcomes in comparison with single-domain prevention trials. These multidomain interventions involve diet, physical exercise, cognitive training and social activities, while music therapy, improving self-consciousness and reducing neurofibrils, may contribute to deceleration/delay onset of Alzheimer's disease progression. Information and Communication Technology (ICT) provides broad applications to improve quality of life and well-being of Alzheimer's disease patients and caregivers, suffering from psychological distress, as well as reducing additional public health costs.
