Health for All: a health literate, culturally competent and participative approach

Background

Three micro projects, planned by the multidisciplinary team in a Primary Care setting targeting refugees and asylum seekers, aim at migrants' health, building strategies together with the private and social sectors involved, for a culturally competent and Health Literate approach, within the ICARE Project activities. Three different areas of work were identified: detecting barriers to migrants' management of prevention and care of Covid-19; preventing domestic accidents in children; improving the participation to screening programs among refugees and women victims of human trafficking.

Objectives

The main objective is to improve migrants' engagement in health care and health promotion activities in a new context of living strongly influenced by the pandemic waves of Covid-19. The second objective is to enable a participative approach to migrants' health among intercultural mediators, nurses, paediatrician, infectious diseases specialist, psychologist, social workers and representatives of No Profit Organizations (NPOs) that support refugees and women victims of human trafficking within the “Oltre la Strada” Regional project.

Results

A closed questionnaire assessing knowledge about prevention and management of Covid-19 has been carried out among 100 refugees and asylum seekers. A video on prevention of domestic accidents was made and translated in eleven languages as a result of a cooperation with intercultural mediators, to encourage questions during the educational meetings. Finally, a focus group was performed with NPOs in order to identify common areas of work, enabling a participative approach to improve migrants' engagement.

Conclusions

The preliminary results reveal the need to approach migrants' health focusing on their participation through a multidimensional, person-centred, Health Literate and culturally competent cooperation. The outcomes from data analysis of the ongoing activities within the ICARE Project will be presented at the conference.

Key messages

A multidimensional approach to migrants’ health enables all stakeholders to learn from each others, improving the awareness about the relationship between health literacy and health outcomes. The cooperation between health, social and private sectors could be strategic for an organizational change towards a person-centred approach.

Effectiveness of the Virtual Reality System Toyra on Upper Limb Function in People with Tetraplegia: A Pilot Randomized Clinical Trial

The aim of this study was to investigate the effects of a virtual reality program combined with conventional therapy in upper limb function in people with tetraplegia and to provide data about patients' satisfaction with the virtual reality system. Thirty-one people with subacute complete cervical tetraplegia participated in the study. Experimental group received 15 sessions with Toyra(®) virtual reality system for 5 weeks, 30 minutes/day, 3 days/week in addition to conventional therapy, while control group only received conventional therapy. All patients were assessed at baseline, after intervention, and at three-month follow-up with a battery of clinical, functional, and satisfaction scales. Control group showed significant improvements in the manual muscle test (p = 0,043, partial η (2) = 0,22) in the follow-up evaluation. Both groups demonstrated clinical, but nonsignificant, changes to their arm function in 4 of the 5 scales used. All patients showed a high level of satisfaction with the virtual reality system. This study showed that virtual reality added to conventional therapy produces similar results in upper limb function compared to only conventional therapy. Moreover, the gaming aspects incorporated in conventional rehabilitation appear to produce high motivation during execution of the assigned tasks. This trial is registered with EudraCT number 2015-002157-35.

A novel FES control paradigm based on muscle synergies for postural rehabilitation therapy with hybrid exoskeletons

Hybrid exoskeletons combine robotic orthoses and motor neuroprosthetic devices to compensate for motor disabilities and assist rehabilitation. The basic idea is to take benefits from the strength of each technology, primarily the power of robotic actuators and the clinical advantages of using patient's muscles, while compensating for the respective weaknesses: weight and autonomy for the former, fatigue and stability for the latter. While a wide repertory of solutions have been proposed in literature for the control of robotic orthoses and simple motor neuroprosthesis, the same problem on a complex hybrid architecture, involving a wide number of muscles distributed on multiple articulations, still waits for a practical solution. In this article we present a general algorithm for the control of the neuroprosthesis in the execution of functional coordinated movements. The method extracts muscle synergies as a mean to diagnose residual neuromotor capabilities, and adapts the rehabilitation exercise to patient requirements in a dynamic way. Fatigue effects and unexpected perturbations are compensated by monitoring functional state variables estimated from sensors in the robot. The proposed concept is applied to a case-study scenario, in which a postural balance rehabilitation therapy is presented.

["Assessment of indoor school environment and identification of measures to protect the respiratory health of school children and adolescents" in a sample of schools in Milan]

The management of indoor air quality in schools needs special attention because it has a strong impact on respiratory health of children with effects also on performance and social development. In Italy a prevention program for indoor environments is provided in the "Guidelines for the prevention of indoor risk factors for allergies and asthma in the school", developed by the Ministry of Health (G.U n. 9 del 13.01.11). In this context, the Ministry of Health has promoted the "Indoor school" project (CCM2010). The main objective of the project is the implementation of these guidelines. In this paper we report the results of the first phase of the project which assessed the knowledge of school principals on issues related to IAQ and building characteristics of the school.

Applicability of a new robotic walking aid in a patient with cerebral palsy. Case report

BACKGROUND

Gait training with the help of assistive technological devices is an innovative field of research in neurological rehabilitation. Most of the available gait training devices do not allow free movement in the environment, which would be the most suitable natural and motivating condition for training children with neurological gait impairment.

AIM

To evaluate the potential applicability of a new robotic walking aid as a tool for gait training in non-ambulatory children with Cerebral Palsy.

DESIGN

Single case study

SETTING

Outpatient regimen

POPULATION

A 11-years-old child unable to stand and walk independently as a result of spastic tetraplegic cerebral palsy (CP).

METHODS

The experimental device was a newly actuated version of a dynamic combined walking and standing aid (NF-Walker®) available in the market which was modified by means of two pneumatic artificial muscles driven by a foot-switch inserted in the shoes. The child was tested at baseline (while maintaining the standing position aided by the non-actuated NF-Walker®) and in the experimental condition (while using the actuated robotic aid). The outcome measures were: 2-minute walking test, 10-metre walking test, respiratory and heart parameters, energy cost of locomotion.

RESULTS

At baseline, the child was unable to perform any autonomous form of locomotion. When assisted by the actuated aid (i.e. during the experimental condition), the child was successful in moving around in his environment. His performance was 19.63 m in the 2-minute walking test and 64 s in the 10-metre walking test. Respiratory and heart parameters were higher than healthy age-matched children both at baseline and in the experimental condition. The energy cost of gait, which was not valuable in the baseline condition, was significantly higher than normality during the experimental condition.

CONCLUSION

The new robotic walking aid may help children suffering from CP with severe impairment of gait to move around in their environment.

CLINICAL REHABILITATION IMPACT

This new robotic walking device may have a potential impact in stimulating the development and in training of gait in children with neurological gait impairment. Future studies are warranted in order to test this hypothesis.

Modular control of mediolateral postural sway

Is voluntary motor control of mediolateral rhythmic sway ruled by modular organization? Answering this question has potential implications in diagnosis and rehabilitation of neurologically impairments. Superficial EMG and computerized dynamic posturography has been used in this study to investigate modular control of six healthy subjects. Postural movements have been performed at three different frequencies to also test the influence of speed on the composition of synergies and activations. Results showed that two synergies account for more than 75% of EMG variance and are shared by all subjects across all frequency conditions. These evidences, together with a functional interpretation of computed muscle synergies, support the existence of consistent modular control across healthy subjects during mediolateral voluntary movements.

Magnetization transfer imaging demonstrates a distributed pattern of microstructural changes of the cerebral cortex in amyotrophic lateral sclerosis

BACKGROUND AND PURPOSE

To date, damage of the cerebral cortex neurons in ALS was investigated by using conventional MR imaging and proton MR spectroscopy. We explored the capability of MTI to map the microstructural changes in cerebral motor and extramotor cortices of patients with ALS.

MATERIALS AND METHODS

Twenty patients with ALS and 17 age-matched healthy controls were enrolled. A high-resolution 3D SPGR sequence with and without MT saturation pulses was obtained on a 1.5T scanner to compute MTR values. Using the FMRIB Software Library tools, we automatically computed the MTR of the cerebral cortex GM in 48 regions of the entire cerebral cortex derived from the standard Harvard-Oxford cortical atlas.

RESULTS

The MTR values were significantly lower in patients with ALS than in healthy controls in the primary motor cortex (precentral gyrus), nonprimary motor areas (superior and middle frontal gyri and superior parietal lobe), and some extramotor areas (frontal pole, planum temporale, and planum polare). No correlation was found between regional MTR values and the severity of clinical deficits or disease duration.

CONCLUSIONS

MTI analysis can detect the distributed pattern of microstructural changes of the GM in the cerebral cortex of patients with ALS with involvement of both the motor and extramotor areas.

Metabolic myopathies: functional evaluation by different exercise testing approaches

Metabolic myopathies are a clinically and etiologically heterogeneous group of disorders due to defects in muscular energy metabolism. They include glycogen storage diseases, fatty acid oxidation defects, and mitochondrial disorders. The typical manifestations of a metabolic myopathy are exercise-induced myalgias, exercise intolerance, and cramps. Evaluating subjects with such symptoms is not easy because of the frequent lack of clinical features. Exercise tests are, therefore, reliable screening tools. Here, we discuss the possible role of such exercise testing techniques in the diagnostic approach of a patient with suspected metabolic myopathy.

Electro-synthesis of Sn-Co nanowires in alumina membranes

A fabrication process of amorphous nanowires of Sn-Co alloys, based on electrodeposition into anodic alumina membranes, is described. It is shown that nanowires of tin-cobalt alloys with different compositions can be produced by varying electrodeposition time and concentration ratio of salts dissolved into the electrolytic bath. Importance of the chelating agent to produce amorphous Sn-Co alloys has also been addressed. Electrodepositions were carried out potentiostatically at -1 V versus Saturated Calomel Electrode and 60 degrees C for times ranging from 10 to 90 minutes; the atomic fraction of Co2+ in the aqueous electrolyte (Co2+/(Co2+ + Sn2+)) was varied from 0.33 to 0.67. Nanowires aspect ratio (height/width) was controlled by adjusting the deposition time. Alloys were characterized by scanning electron microscopy and X-ray diffraction; compositional analysis was performed by energy dispersive spectroscopy and induced coupled plasma. The highest concentration of Co in the alloy was found after 90 min of electrodeposition from a bath containing 67% of Co2+.

Hybrid open and endovascular repair of recurrent visceral aortic patch aneurysmal expansion after previous thoracoabdominal aortic aneurysm repair: case report and description of technique

The rate of morbidity and mortality in patients undergoing open repair for thoracoabdominal aortic aneurysm (TAAA) still remains too high, ranging from 2% to 40%. In recent years "hybrid" techniques have been developed (EVAR and retrograde surgical revascularization) for the treatment of TAAA. This procedure has proved to be more effective to reduce the high risks of complication related to this kind of operation resulting in a lower morbidity and mortality rates when compared to traditional surgical techniques. A 77-year old patient who had previously been undergone surgical exclusion of a TAAA by using a straight aorto to aortic bypass graft (end to end fashion) with visceral patch, was referred to our behalf for the presence of a recurrent Crawford Type IV aortic aneurysm expansion of 10.5 cm length on diameter. Considering the serious co-morbidities of the patient and the high risk of mortality related to the traditional redo surgery, the hybrid technique was considered to repair this recurrent aneurysm by using a surgical debranching of the visceral and renal arteries from the aorta associated to the their retrograde revascularization before to perform the endovascular exclusion of the aneurysm at the same time in a single operation. Over a period of 12 months the patient was alive in good health, a follow-up by computed tomography (CT) scan confirmed the correct position of the endograft, without endoleaks, the patency of the bypasses and the reduction on diameter of the aneurysmal sac. The combined hybrid procedure (endovascular and open surgical approach) for treatment of complex TAAA is to be considered a feasible and effective surgical technique, but a larger number of cases and a longer follow-up are required either to validate this procedure or to get a more significant and statistical comparison to the traditional approach.

Combined spinal and epidural anesthesia for open abdominal aortic aneurysm surgery in vigil patients with severe chronic obstructive pulmonary disease ineligible for endovascular aneurysm repair. Analysis of results and description of the technique

This study evaluated the feasibility of open infrarenal abdominal aortic aneurysm (AAA) surgery under peridural and spinal anesthesia (vigil patient) alone in high-risk patients with severe chronic obstructive pulmonary disease (COPD) ineligible for endovascular aneurysm repair (EVAR) or open surgery in general anesthesia. Between January 2005 and July 2007, seven patients underwent open AAA surgery with combined spinal and epidural anesthesia ([CSEA] without intubation) alone. Regional abdominal anesthesia was established by spinal anesthesia at L2-3 (levobupivacaine plus fentanyl) associated with peridural anesthesia at T7-8 (levobupivacaine). In this series (6 males and 1 female) the average age was 76.5 years (70-87); the AAA measured 7 cm in diameter on average (range 6-12.2). The survival rate was 100% (7/7 patients) at 6-12 months postoperative; no morbidities occurred during the postoperative phase. Owing to the small size of the series, no statistically significant conclusions can be drawn; even so, repair surgery was found to be effective, without the occurrence of morbidities or mortalities. In high-risk patients (severe COPD), open surgical repair of infrarenal AAA may be done with CSEA alone without intubation when, because of the patient's health, general anesthesia would pose too high a risk or when EVAR is unfeasible. Furthermore, the authors believe that surgical AAA repair under CSEA in vigil patients is a valid treatment option in those subjects with a high operative risk (severe COPD) and untreatable by either open AAA surgery under general anesthesia or EVAR.

Visceral artery aneurysms: series of 17 cases treated in a single center

AIM

The aim of this study is to evaluate early and long term results obtained with a retrospective review in 8-year experience with surgical/endovascular treatment of visceral artery aneurysm (VAA) in a single center.

METHODS

Between 2001 and 2008 in our vascular surgery unit visceral artery aneurysms were diagnosed with CT and/or angiography in 17 patients (9 male), mean age 66 years old (range: 18 to 78). All patients underwent surgical or endovascular treatment of splanchnic artery aneurysm. In 14 patients the localization was single, in 3 it was multiple. The arteries involved were: splenic artery 53%, superior mesenteric artery 17.7%, pancreaticoduodenal artery 17.7%, celiac axis 5.8% and hepatic artery 5.8%. The 29.4% of the patients presented with aneurysm rupture. Coil embolizzation was used in 11.6% of the cases while surgery was used in 88.4% of the cases.

RESULTS

Total survival rate was 94.2%, the survival rate in emergency cases was 80% while it was 100% in elective cases. Follow-up revealed excellent results after an average of 46 months (range: 8-102).

CONCLUSION

The worst prognosis for ruptured cases associated with the good result of the surgical/endovascular treatment in elective cases, suggests active interaction for such pathologies; in emergency cases the mortality incidence is too high. Today endovascular treatment presents lower morbidity and mortality rates and shorter hospitalization, but surgery is still a good therapeutic option for the treatment of the VAA, in subjects with low surgical risk, determining a definitive and long-lasting correction of the aneurysmal pathology and guaranteeing the correct perfusion of the organs, by grafts; moreover many aneurysms are not suitable for endovascular treatment.

Mitochondria, cognitive impairment, and Alzheimer's disease

To date, the beta amyloid (Abeta) cascade hypothesis remains the main pathogenetic model of Alzheimer's disease (AD), but its role in the majority of sporadic AD cases is unclear. The "mitochondrial cascade hypothesis" could explain many of the biochemical, genetic, and pathological features of sporadic AD. Somatic mutations in mitochondrial DNA (mtDNA) could cause energy failure, increased oxidative stress, and accumulation of Abeta, which in a vicious cycle reinforce the mtDNA damage and the oxidative stress. Despite the evidence of mitochondrial dysfunction in AD, no causative mutations in the mtDNA have been detected so far. Indeed, results of studies on the role of mtDNA haplogroups in AD are controversial. In this review we discuss the role of the mitochondria, and especially of the mtDNA, in the cascade of events leading to neurodegeneration, dementia, and AD.

Isolated aneurysm of the inferior thyroid artery repair with coil embolization

A 68-year-old female patient with a suspected aneurysm of the inferior thyroid artery was admitted to the authors' Unit of emergency after an accident. The echography of the thyroid revealed a ''suspected'' aneurismal dilation of the inferior thyroid artery (max. diameter 30 mm.). The patient underwent an angiograph of the supra-aortic trunk, which detected a small round formation at the base of the left inferior thyroid artery (found to be unaffected by aneurismal pathologies), the aneurysm was excluded by coil embolization. The postoperative course was uneventful and the patient was discharged in one day without complications. The follow-up with colour Duplex, at 4-8 months, showed the normal vascularization of the neck arterial vessels and was confirmed the absence of aneurysmal dilations. Aneurysms of the inferior thyroid artery are extremely rare, in scientific literature only 28 cases have been reported of which 32.9% regard ruptured aneurysms in the thyroid artery and 10.7% led to mortality. They may cause dysphagia and/or respiratory difficulties. Therefore, treatment is always recommended, even in asymptomatic cases, by surgical exclusion or coil embolization.

Antioxidant capacity and protein oxidation in cerebrospinal fluid of amyotrophic lateral sclerosis

BACKGROUND

The causes of Amyotrophic Lateral Sclerosis (ALS) are unknown. A bulk of evidence supports the hypothesis that oxidative stress and mitochondrial dysfunction can be implicated in ALS pathogenesis. METHODS =: We assessed, in cerebrospinal fluid (CSF) and in plasma of 49 ALS patients and 8 controls, the amount of oxidized proteins (AOPP, advanced oxidation protein products), the total antioxidant capacity (FRA, the ferric reducing ability), and, in CSF, two oxidation products, the 4-hydroxynonenal and the sum of nitrites plus nitrates.

RESULTS

The FRA was decreased (p = 0.003) in CSF, and AOPP were increased in both CSF (p = 0.0039) and plasma (p = 0.001) of ALS patients. The content of AOPP was differently represented in CSF of ALS clinical subsets, resulting in increase in the common and pseudopolyneuropathic forms (p < 0.001) and nearly undetectable in the bulbar form, as in controls. The sum of nitrites plus nitrates and 4-hydroxynonenal were unchanged in ALS patients compared with controls.

CONCLUSION

Our results, while confirming the occurrence of oxidative stress in ALS, indicate how its effects can be stratified and therefore implicated differently in the pathogenesis of different clinical forms of ALS.

The transcriptional landscape of the mammalian genome

This study describes comprehensive polling of transcription start and termination sites and analysis of previously unidentified full-length complementary DNAs derived from the mouse genome. We identify the 5' and 3' boundaries of 181,047 transcripts with extensive variation in transcripts arising from alternative promoter usage, splicing, and polyadenylation. There are 16,247 new mouse protein-coding transcripts, including 5154 encoding previously unidentified proteins. Genomic mapping of the transcriptome reveals transcriptional forests, with overlapping transcription on both strands, separated by deserts in which few transcripts are observed. The data provide a comprehensive platform for the comparative analysis of mammalian transcriptional regulation in differentiation and development.

Comparison of benazepril-amlodipine and captopril-thiazide combinations in the management of mild-to-moderate hypertension

OBJECTIVE

To compare the efficacy and tolerability of benazepril 10 mg + amlodipine 5 mg combination (BZ+AM) versus captopril 50 mg + hydrochlorothiazide 25 mg (CP+HT) combination.

MATERIAL

405 outpatients with mild-to-moderate arterial hypertension not adequately controlled by a monotherapy with ACE inhibitors or calcium channel blockers or diuretics entered this multicenter, double-blind, randomized, parallel-group study.

METHOD

After a 2-week placebo run-in, 397 patients with sitting diastolic (D) blood pressure (BP) > 95 mmHg and/or sitting systolic (S) BP > 160 mmHg were randomized to receive either BZ+AM (201 patients) or CP+HT (196 patients) once daily for 12 weeks. Main outcome measure was sitting DBP and SBP values at the end of active treatment. The response rate was defined as the proportion of patients with either a final sitting DBP < 90 mmHg or decreased by at least 10 mmHg or a sitting SBP < 150 mmHg or decreased by at least 20 mmHg from baseline.

RESULTS

The DBP and SBP values obtained with BZ+AM were, respectively, 2.7 and 3.7 mmHg lower than those obtained with CP+HT (both p < 0.001 vs. CP+HT). The response rate in the BZ+AM group (94.8%) was better than that observed in the CP+HT group (86.0%, p = 0.004). The incidence of adverse events was similar with the 2 treatment regimens (17.9% for both).

CONCLUSIONS

These data suggest a higher antihypertensive efficacy of the fixed combination BZ 10 mg+AM 5 mg as compared with CP 50 mg+HT 25 mg.

Modifications of cardiac autonomic profile associated with a shift schedule of work

BACKGROUND

Shift work is associated with an increased rate of cardiovascular diseases and accidents. Discordance between circadian rhythms of stress-related biological variables and the work-sleep schedule might explain the reduced efficiency of work. It is not clear whether a shift schedule of work may induce similar discordance in the 24-hour oscillatory pattern of the cardiac autonomic control in respect to the work-sleep periods.

METHODS AND RESULTS

Twenty-two healthy male blue-collar shift workers underwent 24-hour ECG recordings during each of the 3 different shifts (first, 6 AM to 2 PM; second, 2 to 10 PM; third, 10 PM to 6 AM). Spectral analysis of heart rate variability over 24 hours provided the normalized markers of cardiac sympathetic (LF(nu)) and vagal (HF(nu)) modulation of the sinoatrial node activity and of the sympathovagal balance (LF/HF). LF(nu) and LF/HF exhibited 24-hour oscillations with different times of maximum and minimum in accordance with the working and sleeping periods, respectively. Lower values of LF(nu) and LF/HF suggestive of a reduced cardiac sympathetic modulation were present when the job task was performed at night compared with the values observed when the work was performed during morning and evening.

CONCLUSIONS

Continuous weekly changes of time of maximum and minimum in the cardiac sympathetic and vagal autonomic control may play a role in the excessive rate of cardiovascular diseases in shift workers. The reduced values of the indexes of cardiac sympathetic modulation during night work might be related to the presence of sleepiness or diminished alertness, which in turn could facilitate errors and accidents.

Cardiac autonomic patterns preceding occasional vasovagal reactions in healthy humans

BACKGROUND

The wide range of clinical presentation of orthostatic vasovagal syncope suggests different underlying changes in the cardiac autonomic modulation.

METHODS AND RESULTS

To evaluate the beat-by-beat modifications in the neural control of heart period preceding a syncopal event, we studied RR interval variability in 22 healthy subjects who experienced fainting for the first time during a 90 degrees head-up tilt and in 22 control subjects by means of time-variant power spectral analysis. Sympathetic and vagal modulations to the sinoatrial node were assessed by the normalized power of the low-frequency (LF, approximately 0.1-Hz) and high-frequency (HF, approximately 0.25-Hz) oscillatory components of RR variability. When the patients were supine, no differences were observed in the hemodynamic and spectral parameters of the 2 groups. During the tilt procedure, RR, LFNU, and HFNU (NU=normalized units) values were relatively stable in control subjects. During early tilt (T1), subjects with syncope had reduced RR intervals compared with control subjects. In 13 subjects with syncope, RR decreased while LFNU and LF/HF increased in the last minute of tilt before syncope (T2). Conversely, in the remaining 9 fainters, LFNU and LF/HF decreased from T1 to T2 and HFNU increased slightly.

CONCLUSIONS

Two different patterns may be recognized in the cardiac autonomic changes preceding an occasional vasovagal event, namely, one characterized by a progressive increase of the marker of cardiac sympathetic modulation up to the onset of syncope, the other by a sympathetic inhibition with an impending vagal predominance. The recognition of different pathophysiological mechanisms in fainters may have important therapeutic implications.
