Human factor of The Use Of Robotic Technology In Pediatric neurorehabilitation

Robotic technology represents a new rehabilitation opportunity that, with an approach similar to a video game, increases the motivation to treat children and seems able to activate brain plasticity, at the basis of the functional recovery due to its interactivity and intensity of the training experience. Literature reports few studies that evaluate the ergonomic aspects of devices for neurorehabilitation, from the point of view of both the operator and the patient. Similar studies in the pediatric field are rare. This study aims to evaluate the response of workers, patients and their parents to this new technology.

The study considered the response of the workers (perception of the workload, satisfaction), that of the patients and their parents (expectations, benefits) by comparing the answers to subjective questionnaires of those who made use of the new technology with those who used the traditional technique. Twelve workers, 46 patients and 47 parents were enrolled in the study.

Significant differences were recorded in the total workload score of operators who use the robotic technology compared to the traditional therapy (p < 0.001). Patients reported a higher quality of life and satisfaction after the use of robotic neurorehabilitation therapy. The parents of patients undergoing robotic therapy have moderately higher expectations and satisfaction than those undergoing traditional therapy. None of the parameters checked was worse in the new therapeutic technique than in the traditional one.

In this pilot study, the robotic neurorehabilitation technique induced an increase in the expectations and satisfaction of patients and their parents. As is frequent in the introduction of new technologies, workers perceived a greater workload. Subsequent studies are needed to verify the results achieved. This study is being developed in an Italian pediatric hospital, with the collaboration and funding of the Italian Ministry of Health, coauthor of this study.

Key messages

Robotic therapy presents a higher workload compared to traditional one. Robotic technique induced an increase in quality of life of patients and in expectations and satisfaction of their parents.

Integrated strategies of participatory surveillance to promote flu vaccine coverage in HCWs

Problem

Influenza represents a threat for healthcare facilities where sudden outbreaks of illness can lead to high morbidity and mortality in vulnerable patients and increase absenteeism in HCWs. Despite WHO recommends annual influenza vaccination of HCWs, flu vaccine coverage (FVC) remain very low in most EU countries.

Description of the Problem

Despite an important increase in FVC recorded in last years in our hospital, FVC remains under 75%. We pilot a prospective cohort study in HCWs in order to test new methods for influenza vaccination promotion. We create a web-based system integrating information on vaccination status (unvaccinated HCWs, 1/2/3 years vaccinated ones) and demographic data. The Hospital Ethical Committee approved the study. During the 2019/20 influenza season we nested a test-negative case-control study in the cohort to evaluate Influenza vaccine effectiveness against influenza-like-illness (ILI) laboratory confirmed as influenza in HCWs.

Results

A total of 443 on 2675 HCWs were recruited in the cohort and weekly received specific SMS messages and phone call for a personal invitation to get flu shot. The median age of the cohort was 43,3 (range 21-72) with 128 male (28,9%). In the cohort a FVC of 26/205 (12,7%) was registered in HCWs never vaccinated in the previous 3 seasons. Nasopharyngeal swabs were distributed to 205 subjects for influenza confirmation and they received weekly messages in order to check their health status remanding to self-swab in the case of ILI symptoms.

Lessons

Using a new and integrated strategy for influenza vaccination promotion in HCWs can increase the FVC. The use of personal direct messages to HCWs and the possibility of confirming or excluding influenza in case of ILI symptoms in those vaccinated and unvaccinated, seems to be very effective in increasing vaccine coverage. Moreover, the cohort could be also used for further research studies as for example the effect of repeated influenza vaccination.

Key messages

The presented practice appears to be effective and could be applied to larger HCWs population. This strategy could be considered as a good practice of workplace vaccination promotion.

Tuberculosis latent infection in health care workers: oxidative stress and Quantiferon-TB Plus

Background

This study moves from recent evidences highlighting: 1) the high sensitivity of Mycobacterium tuberculosis (MT) to perturbation of redox homeostasis induced by oxidative stress; 2) the improvement of Tuberculosis (TB) diagnosis following the introduction of Quantiferon-TB Plus (QFT-Plus) assay.

Methods

The QFT-Plus diagnostic performance and the blood antioxidant capacity, expressed as ratio between oxidized (GSSG) and reduced (GSH) forms of glutathione, were determined on three selected populations (40 Health care workers (HCWs) controls, 63 latent TB HCWs, 8 active TB patients). Quantitative Real Time PCR analysis on leukocytes of active TB patients was also performed, in order to identify “redox profiles” of genes mainly involved in the antioxidant response.

Results

1) The glutathione homeostasis was shifted towards an oxidative status in active TB patients respect to controls, as evidenced by the significant decrease of the ratio between free and total GSH, an indirect index of oxidative stress. More reducing conditions were observed in latent TB subjects. 2) The expression profiles of antioxidant genes confirmed the major susceptibility of active TB patients to oxidative stress compared to controls, and highlighted a great individual variability. 3) The diagnostic performance of QFT-Plus test present a moderate concordance with QFT-GIT one, in this preliminary phase.

Conclusions

Glutathione has anti-mycobacterial effects in its reduced form GSH, thus the quantification of Free/Total GSH ratio may represent a systemic marker of TB infection and be useful in developing combined therapies. Moreover, the identification of personalized redox profiles will additionally provide an individual antioxidant response to the infection.

This project was funded by the Ministry of Health (RF 2016)

Key messages

LTBI management represents an objective of primary importance in the field of occupational medicine in order to define a personalized prevention in HCW. A new approach that combines biochemical determinations of redox biomarkers and gene expression in blood will be a novel biomarkers of tuberculosis.

Frailty screening and assessment tools: a review of characteristics and use in Public Health

INTRODUCTION

Frailty screening and assessment are a fundamental issue in Public Health in order to plan prevention programs and services.

METHODOLOGY

By a narrative review of the literature employing the International Narrative Systematic Assessment tool, the authors aims to develop an updated framework for the main procedures and measurement tools to assess frailty in older adults, paying attention to the use in the primary care setting.

RESULTS

The study selected 10 reviews published between January 2010 and December 2016 that define some characteristics of the main tools used to measure the frailty. Within the selected reviews only one of the described tools met all the criteria (multidimensionality, quick and easy administration, accurate risk prediction of negative outcomes and high sensitivity and specificity) necessary for a screening tool.

CONCLUSION

Accurate risk prediction of negative outcomes could be the appropriate and sufficient criteria to assess a tool aimed to detect frailty in the community-dwelling elderly population. A two-step process (a first short questionnaire to detect frailty and a second longer questionnaire to define the care demand at individual level) could represent the appropriate pathway for planning care services at community level.

Risk of fall among the hospitalized over-49 population. A retrospective cohort study in a hospital

Background

Despite the copious efforts made to prevent the problem, inpatient falls remain one of the most common adverse events in hospitals, with high risks in term of morbidity and mortality rates, as well as high costs for the healthcare system. This study aims to evaluate the inpatient falls incidence rate in a hospital in Rome, Italy.

Methods

A retrospective cohort study has been set out based on data collected by a Risk Management Unit concerning the falls of patients over 49 years, which happened in the hospital between 1st July 2008 and 30th June 2013. Data collected from the incident report forms were inserted in a database and analyzed using the statistical program SPSS, 20.0 Illinois version.

Results

During the period observed, 516 falls were reported. Patients who fell had a mean age of 68.8 years (SD ± 16.2). The falls are distributed for these age groups: 109 (21.1%) in 50-64; 129 (25%) in 65-74; 181 (35.1%) in 75-84; 97 (18.8%) in > 84. Fall incidence rate was calculated on the overall number of hospital admissions in the observed period (N = 35,812) (1.44 per 100 hospital admissions IC95% 1.32-1.56). Most of the patients were men (333; 64.5%) and older than 75 (53.9%). Inpatient falls were more frequent in the medicine wards (incidence rate 2.2 per 100 hospital admissions, IC95% 1.85-2.55,). The 51.6% of falls happened during the night shift. Severe outcome resulted in 13.6% of falls. Most of the falls (52.3%) happened within three days from the hospital admission. At multivariate analysis, a period of 2-3 days from hospital admission is the main risk factor to determine severe outcomes such as death or cranial trauma (p = 0.02; OR 2.87 IC95% 1.16-7.09).

Conclusions

The study contributes to measure the phenomenon in older adults and age group 50-64, identifying a specific indicator to properly measure inpatient falls incidence rate in the elderly. The study gives indications on the main risk factors related to this adverse event and on prevention strategies.

Key messages

Falls in hospital is an important adverse event not only in the elderly. The first period of three days from the hospital admission constitutes the main risk factor for the falls.

Nitrous oxide occupational exposure in conscious sedation procedures in dental ambulatories: a pilot retrospective observational study in an Italian pediatric hospital

BACKGROUND

Nitrous oxide has a proven clinical efficacy in conscious sedation. At certain environmental concentrations it may pose a health risk to chronically exposed healthcare workers. The present pilot study aims at evaluating the exposure to nitrous oxide of dental ambulatory personnel of a pediatric hospital.

METHODS

A descriptive study design was conducted in two phases: a bibliographic analysis on the environmental safety policies and a gas concentration analysis in the dental ambulatories of a pediatric hospital, detected every 6 months from December 2013 to February 2017 according to law provisions. The surveys were carried out using for gas analysis a photoacoustic spectrometer Innova-B&K "Multi-gas monitor model 1312" and Innova-B&K "Multi-sampler model 1309". The biological analysis and monitoring have been carried out on staff urine.

RESULTS

The analyses were performed during 11 dental outpatient sessions on pediatric patients. All the patients were submitted to the same dental procedures, conservative care and dental extractions. The pediatric patients were 47 (23 males, 24 females; age range 3-17 years; mean age 6,63, SD ± 2,69) for a mean of 4,27 (SD ± 1,49) per session., The mean environmental concentration of nitrous oxide during the sessions was 24.7 ppm (SD ±16,16). A correlation was found between urinary nitrous oxide concentration of dentists (Pearson's correlation 0.786; p = 0.007) and dental assistants urines (Pearson's correlation 0.918; p < 0.001) and environmental concentrations of nitrous oxide. Weak negative correlations were found between age and sex of patients and environmental concentrations of nitrous oxide. The mean values of the biological monitoring data referring to all the outpatient sessions are lower than the reference values foreseen in accordance to the regulations in force on nitrous oxide concentration.

CONCLUSIONS

The mean environmental concentration values recorded in our study are below the limit of 50 ppm considered as a reference point, a value lower than those reported in other similar surveys. The results of the present study provide a contribution to the need to implement technical standards, criteria and system requirements for the dental ambulatories, to date not yet completely defined, and cannot be assimilated to the ones established for the surgical rooms.

Trend and determinants of acute inpatient care for the elderly in Italy from 2001 to 2011

BACKGROUND

The population over 64 years of age is the main user of acute hospital care services. The elderly admission rates represent a marker for the appropriateness of the model of care. The aim of this study was to assess trends and determinants of acute in-patient care among the elderly in Italy between 2001 and 2011.

STUDY DESIGN

Retrospective analysis of data included in the Italian Hospital Discharge Form Database.

METHODS

Data from the Italian Hospital Discharge Form Database, Italian Ministry of Health, for the years 2001, 2006 and 2011 were analyzed for individuals over 64 years of age. Inpatient admission (> 1 day) rates across Italian Regions were calculated and compared with demographic variables and out-of-hospital care indicators. Univariate and multivariate analysis were used to determine independent relationship among variables.

RESULTS

From 2001 to 2011 the elderly hospital admission rate decreased from 302.1/1,000 in 2001, to 222.4 in 2011, accounting for an overall decrease of about 28%. The decline in admission rates was less pronounced among individuals > 74 y (26.4%) than among those 65-74 y (32.1%). Hospitalization rates decreased in all Italian administrative regions between 2001 and 2011, even if the hospitalization rates in 2011 were still very different through the different Italian regions, ranging from 180.3/1,000 in Piedmont to 278.1/1,000 in Molise for people > 64 y. The multivariate linear regression was statistically significant in explaining the variations in hospitalization rates among the different Italian administrative regions (F: 3.637; p = 0.024; adjusted R2 = 0.57) and pointed to the role played by the proportion of the elderly (as percentage of the total population, p=0.043) and the rate of variation of acute care beds from 2004 to 2011 (p=0.001). Variables related to community-based care did not show any association with the hospital admissions rate among the elderly.

CONCLUSIONS

The trend toward decline in elderly inpatient admissions is still present in 2011 as it was in 2001. Determinants of elderly hospital care in Italy are related to the increased number of elderly individuals and the reduction of hospital beds. Out-of-hospital care does not correlate with the variation of in-patient care so the overall care appropriateness could be negatively affected.

The European Innovation Partnership on Active and Healthy Ageing Synergies: Protocol for a Prospective Observational Study to Measure the Impact of a Community-Based Program on Prevention and Mitigation of Frailty (ICP - PMF) in Community-Dwelling Older Adults

Aim of this paper is to describe the protocol of the study "Impact of a Community-based Program on Prevention and Mitigation of Frailty in community-dwelling older adults" developed in the framework of the European Innovation Partnership on Active and Healthy Ageing. This proposal has been developed by the Partnership Action groups on frailty, fall prevention and polypharmacy in older. The proposal wants to assess the impact of community-based programs aimed to counteract three main outcomes related to frailty: hospitalization, institutionalization and death. Bringing together researchers from seven European countries, the proposal aims to achieve the critical mass and the geographical extension enough to provide information useful to all older European citizens. An observational study will be carried out to calculate the incidence of the different outcomes in relation to the various interventions that will be assessed; results will be compared with data coming from already established national, regional and local dataset using the observed/expected approach. The sample will be made up by at least 2000 citizens for each outcome. All the citizens will be assessed at the baseline with two multidimensional questionnaires: the RISC questionnaire and the Short Functional Geriatric Evaluation questionnaire. The outcomes will be assessed every six-twelve months.

Unequal access, low vaccination coverage, growth retardation rates among immigrants children in Italy exacerbated in Roma immigrants

AIM

Currently children of immigrants are the fastest growing segment of the Italian population under the age of 18. The present study reports the challenges to health services access, the vaccination coverage, the health and nutritional status of a sample of 1310 children of immigrants attended from February 2004 to May 2012 the health center "Medicina Solidale" of the "Policlinico Tor Vergata" in the suburban area of the VIII Municipality of Rome.

METHODS

The data were collected using clinical archives of the health center. We analyzed the socio-demographic conditions, health problems and nutritional status on admission to the health center. The anthropometric evaluation was carried out according to international standards of child growth WHO 2006 and the statistical analysis was performed using SPSS version 19, and including risk estimation, Mantel Haentzel statistics and t-test.

RESULTS

Sixty-six percent of the children were born in Italy, 62% had never had regular health care and 3.4% of children older than six months had never received any of the immunizations. It has been estimated that being Roma the risk of not been vaccinated is equal to OR=5.4 (IC95%: 2.8-10.1). Seventy-seven percent of unvaccinated children had at least one illiterate parent. This condition was strongly associated with non-immunization (OR=15:36 [IC95%: 6.4-36.4]). Growth retardation was common in Roma children as compared to other ethnicities.

CONCLUSION

Significant public health efforts are needed to improve access to health services for immigrant populations and to solve relevant inequalities.

[Inconsistency between voltage of the electrocardiogram and the left ventricular wall thickness. diagnostic key in cardiac amyloidosis]

Restrictive cardiomyopathy is the least common form of cardiomyopathy, and the disease that most often cause it, is the system amyloidosis. We present a 62-year-old with a history of heart failure, which in its assessment highlights the discrepancy between the low voltage ventricular complexes in the electrocardiogram and the severity of left ventricular wall thickness on echocardiography. This discrepancy was the source of suspicion and subsequent confirmation of systemic amyloidosis with cardiac involvement.

[Acute hospital care for the elderly in Italy: comparison between 2001 and 2006]

The continous health expenditure increase in developed countries is often related with the acute hospital care of the elderly. To monitor the characteristics of elderly acute hospital care included the expenditure trend is crucial in order to identify the appropriateness of this care. The aim of this study is to describe quality and quantity of in-hospital care use of elderly population in Italy in 2006 and to compare the results with the same information gathered for 1996 and 2001. All the 2006 acute hospital admission longer than one day of the patients older than 64 years sourced from the Register of Discharge Form of the Italian Ministry of Health have been analyzed. A list of the 30 more frequent diagnoses has been compiled and compared with the same list compiled for 2001. On the basis of the National Fee for each Disease Related Group an analysis of the hospital expenditure has been carried out. The correlation between DRGs National Fees and frequency of the diagnosis in the discharge form has been based on the 80 diagnosis that has been recorded for more than 10.000 discharge forms in 2006. A relevant increase of acute hospital admission for respiratory, cardiovascular and urinary pathologies among the elderly has been observed. Moreover the number of hospital admissions for major joints and implant of lower limbs is doubled from 1996. The total health expenditure for the elderly acute care longer than one day is increased of 6.3% and a positive correlation between higher DRGs fees and higher frequency of diagnosis has been observed (Pearson correlation value = 0.478; p<0.001 - cubic regression R-square value = 0.301; p<0.001). The hospital acute care use of the elderly patients seems to be more related to emergency care than in the past, while a decrease of DRGs related to chronic diseases and generic diagnosis has been observed. The more frequent cause of in-hospital admission seems to be related also to a higher DRGs fee. As already observed in the past years, a trend towards the use of more expensive DRGs could be detected.

Bile acids and their signaling pathways: eclectic regulators of diverse cellular functions

The field of bile acids has witnessed an impulse in the last two decades. This has been the result of cloning the genes encoding enzymes of bile acid synthesis and their transporters. There is no doubt that the identification of Farnesoid X Receptor (FXR, NR1H4) as the bile acid receptor has contributed substantially to attract the interest of scientists in this area. When FXR was cloned by Forman et al. [1], farnesol metabolites were initially considered the physiological ligands. After identifying FXR and other nuclear receptors as bile acid sensors [2-4], it has become clear that bile acids are involved in the regulation of lipid and glucose metabolism and that these molecules are eclectic regulators of diverse cellular functions. In this review, we will summarize the current knowledge of the functions regulated by bile acids and how their physiological receptors mediate the signaling underlying numerous cellular responses.

LXR (liver X receptor) and HNF-4 (hepatocyte nuclear factor-4): key regulators in reverse cholesterol transport

Cholesterol homoeostasis is the result of the fine tuning between intake and disposal of this molecule. High levels of cholesterol in the blood are detrimental as they may lead to excessive accumulation in vessel walls, a condition predisposing to the development of atherosclerotic lesions. Cholesterol is removed from the vessel wall and transported to the liver through a process called reverse cholesterol transport. Nuclear receptors are among the most important transcription factors regulating genes involved in different steps of reverse cholesterol transport. Here, we discuss the role of the nuclear receptors LXR (liver X receptor) and HNF-4alpha (hepatocyte nuclear factor-4alpha) in different steps of reverse cholesterol transport. LXR controls the transcription of crucial genes in cholesterol efflux from macrophages and its transport to the liver, such as ABCA1 (ATP binding cassette A1), CYP27A1 (sterol 27-hydroxylase), CLA-1 (scavenger receptor type B1) and apolipoprotein E. Some oxysterols present in oxidized low-density lipoproteins and proinflammatory cytokines modulate the activity of LXR by antagonizing the effect of activators of this receptor, thus contributing to cholesterol accumulation in macrophages. Bile acid synthesis, which represents the final step of reverse cholesterol transport, is transcriptionally regulated by several nuclear receptors at the level of the liver-specific cytochrome P450 cholesterol 7alpha-hydroxylase (CYP7A1), the rate-limiting enzyme of this metabolic pathway. Bile acids returning to the liver through the enterohepatic circulation down-regulate CYP7A1 transcription via the bile acid sensors farnesoid X receptor and HNF-4alpha. Based on this evidence, these nuclear receptors are candidate targets of new drugs for the treatment and prevention of atherosclerotic disease.
