The rehabilitation of paretic stroke patients uses a wide range of intervention programs to improve the function of impaired upper limb. A new rehabilitative approach, called action observation ...therapy (AOT) is based on the discovery of mirror neurons and has been used to improve the motor functions of adult stroke patients and children with cerebral palsy. Recently, virtual reality (VR) has provided the potential to increase the frequency and effectiveness of rehabilitation treatment by offering challenging and motivating tasks. METHODS: The purpose of the present project is to design a randomized controlled six-month follow-up trial (RCT) to evaluate whether action observation (AO) added to standard VR (AO + VR) is effective in improving upper limb function in patients with stroke, compared with a control treatment consisting of observation of naturalistic scenes (CO) without any action content, followed by VR training (CO + VR).
AO + VR treatment may provide an addition to the rehabilitative interventions currently available for recovery after stroke and could be utilized within standard sensorimotor training or in individualized tele-rehabilitation.
The trial has been prospectively registered on ClinicalTrials.gov. NCT05163210 . 17 December 2021.

In people with multiple sclerosis (PwMS), strict follow-up is essential. Telemedicine has the potential to overcome many of the difficulties in routine management. Herein, we present a structured ...protocol that can be used to remotely manage patients with MS, describing in detail the steps to be taken and exams needed at each stage. A working group was established which developed a tailored protocol that can be adapted to a variety of settings. The overall protocol consisted of 5 phases: enrolment, document sharing phase, pre-evaluation, virtual visit, and post-visit phase, which was divided into 14 individual steps. As of October 2020, 25 virtual visits have been carried out, all via Skype. The patient’s caregiver was present during visits and had an active role. The average duration of the virtual visit was 24 min, and that of the pre-visit and post-visit were around 15 min each. Overall satisfaction as rated by physicians was considered high (8.0 ± 0.5). Using the system usability scale (SUS), patients also favorably rated the virtual visit (96.6 ± 6.1). In 20% of cases, the virtual visit was not sufficient to provide adequate information and an in-person clinical visit was recommended. The described protocol has the potential to provide benefits for the healthcare system as well as patients and their caregivers both during and beyond COVID-19 pandemic.
Hand hygiene plays a pivotal role in preventing Healthcare-Associated Infections (HAIs). Nevertheless, the quality of hand disinfection techniques remains suboptimal, and the reliability of ...assessment methodologies is notably lacking. This study aimed to evaluate hand disinfection techniques using an automated system in an Italian research hospital. Hospital employees underwent automated hand-disinfection technique assessment, according to the World Health Organization's six-step protocol, at a basal time and two further times. Detection was carried out with a scanner that evaluated the effective hand disinfectant coverage through a fluorescent dye present in the hydro-alcoholic gel rub. The hand-hygiene technique of 222 employees was analyzed by HandInScan
. At the initial assessment of hand coverage with the hydro-alcoholic gel, the mean palm coverage was 82.2%, mean back coverage was 66.8%, and overall mean hand coverage was 74.5%. Then, two measurements were performed in June (t1) and December 2022 (t2). The third measurement showed an increase in hand coverage, with a mean palm coverage of 97.2%, a mean back coverage of 91.8%, and a mean hand coverage of 94.5% (
< 0.05). Moreover, the mean coverage of the hand-back was lower than that of the hand-palm at all times (
< 0.001). The automated scanner provided evidence supporting its effectiveness in enhancing hand hygiene among hospital employees. These findings have motivated researchers to conduct long-term studies, given the potential effects on HAI prevention-including their impact on HAI trends.
The aim of the study was to evaluate the usefulness of Holter monitoring for the detection of silent myocardial ischemia (SMI) in elderly type 2 diabetic patients with hypertension and the possible ...relationship between SMI and cardiovascular autonomic neuropathy (CAN). Two hundred and forty-three asymptomatic outpatients, aged 65–75 years, with type 2 diabetes and essential hypertension underwent 24-h ECG monitoring and 5 tests for the evaluation of both parasympathetic (heart rate variability, response to breath deeping, and Valsalva manoeuvre) and sympathetic (cold pressor test and orthostatic hypotension test) autonomic function. A total of 518 asymptomatic episodes of ST depression during Holter monitoring indicative of SMI were detected in 51 of the 243 studied patients (20.9 %). None of the patients with ST depression episodes exhibited a normal response to at least one of the evaluated autonomic function tests, whereas 22 of the 192 patients without ST changes (11.4 %) exhibited a normal response to all tests. Abnormality in both parasympathetic and sympathetic function test responses was found in 94.1 % of patients with ST depression episodes vs 26.1 % of those without ST changes (
P
< 0.001). Statistical evaluation of the relationship between the abnormal response to single autonomic function test and episodes of ST depression was highly significant for all the 5 tests (
P
< 0.001). These results indicate that: (a) Holter monitoring enables to detect ST segment changes indicative of SMI in 20.9 % of elderly diabetic patients with hypertension; (b) the presence of autonomic cardiac dysfunction in these patients suggests a role of diabetic neuropathy in the pathogenesis of SMI; and (c) findings of severe autonomic dysfunction in more than 25 % of patients without ST depression episodes suggest that these patients might be at risk of myocardial ischemia and should possibly be addressed to closer specialistic evaluation, since Holter monitoring might have not detected SMI in these patients due to its low sensitivity and relatively short duration of recordings.
The aim of this study was to compare the effect of ramipril/canrenone versus ramipril/hydrochlorothiazide (HCTZ) combination on atrial fibrillation (AF) recurrence in type 2 diabetic hypertensives ...with and without cardiac autonomic neuropathy (CAN).
A total of 289 hypertensive type 2 diabetic patients, 95 with CAN, in sinus rhythm but with at least two episodes of AF in the previous 6 months were randomized to ramipril 5 mg plus canrenone 50 mg (titrated to 10/100 mg) or to ramipril 5 mg plus HCTZ 12.5 mg (titrated to 10/25 mg) or to amlodipine 5 mg (titrated to 10 mg) for 1 year. Clinic blood pressure (BP) and a 24-h ECG were evaluated monthly. Patients were asked to report any episode of symptomatic AF and to perform an ECG as early as possible. Serum procollagen type I carboxy-terminal peptide (PIP) and carboxy-terminal telopeptide of collagen type I (CITP) were evaluated before and after each treatment period.
Blood pressure was similarly and significantly reduced by all treatments. A total of 51% of patients with amlodipine had a recurrence of AF, as did 31% of patients with ramipril/HCTZ (
< 0.05 vs. amlodipine) and 13% of patients with ramipril/canrenone (
< 0.01 vs. amlodipine and
< 0.05 vs. ramipril/HCTZ). A similar trend was found in diabetic patients with CAN. Both combinations reduced PIP and increased CITP, but the effects of ramipril/canrenone were significantly more marked.
These findings suggest that in type 2 diabetic hypertensives, ramipril/canrenone treatment was more effective than ramipril/HCTZ in reducing AF recurrence. This could be related to the greater improvement in cardiac fibrosis.
Healthcare-Associated-Infections are a critical concern in healthcare settings, posing serious threats to patient safety and causing significant morbidity, mortality, and financial strain. This study ...aims to calculate healthcare-associated-infections trends in the hospital setting through an automatic reporting system.
The study is a descriptive analysis of automatically generated trends of an innovative digital tool based on existing hospital information flows.
An algorithm was developed within a Clinical Information System to create a suite of quality indicators for monitoring healthcare-associated-infections trends. The algorithm used criteria related to admission, laboratory tests and antimicrobial administrations. A descriptive analysis was conducted for patients aged 18 or older, admitted to a neurological or to a neuro-rehabilitation department of a neurologic hospital from 2019 to 2022.
The results showed fluctuations in healthcare-associated-infections prevalence from 2.9% to 5.6% and hospital infec-tions prevalence from 4.5% to 10.9%, with notable increases in 2020 and 2021. The majority (70.3%) of healthcare associated infections identified by the tool were confirmed to be potentially hospital-acquired, according to the European Centre of Disease Prevention and Control's definition.
The study posits the algorithm as a vital tool for automatically monitoring hospital infections, providing valuable preliminary results for improving care quality and guiding the infections' prevention and control strategies, with plans to benchmark the algorithm against a gold standard in the future.
Previous studies have suggested that evening intake of benzodiazepine affects blood pressure (BP) and/or heart rate (HR) in healthy and hypertensive subjects. The aim of this study was to compare the ...effect of chronic oral administration of alprazolam and lorazepam as hypnotics on ambulatory BP and HR in patients with mild hypertension.
Consecutive outpatients of both sexes with newly diagnosed, never-treated mild hypertension were randomized, after a 4-week placebo run-in period, to receive alprazolam 0.5 mg plus placebo, lorazepam 1 mg plus placebo, or placebo plus placebo for 2 weeks in 3 crossover periods, each separated by a 1-week placebo wash-out period. At the end of the initial placebo run-in and of each treatment period, 24-hour ambulatory BP and HR monitoring was performed using a noninvasive device.
In the 32 patients, no treatment had any effect on 24-hour and daytime systolic BP (SBP), diastolic BP (DBP), and HR, which remained unchanged. During the nighttime, SBP and DBP values were unaffected by alprazolam, as compared with placebo, whereas DBP was significantly higher after treatment with lorazepam (+3.7%, P < 0.05 vs placebo). Nocturnal HR mean values were significantly increased by lorazepam (+10.1%, P < 0.01 vs placebo), whereas they did not change after alprazolam.
In patients with mild hypertension, oral intake of alprazolam or lorazepam as hypnotics did not affect ambulatory BP or HR values. A slight increase in nighttime DBP was observed with lorazepam, whereas alprazolam showed no effect on nocturnal BP and HR, probably reflecting a stimulating effect of the drug on central α2-receptors.
Purpose
The present study was carried out in order to assess the effects of chronic administration of flunitrazepam (as an oral hypnotic) on 24-h blood pressure (BP) and heart rate (HR) in healthy ...young adults.
Materials and methods
Following a 2-week placebo run-in period, 28 healthy volunteers (13 males and 15 females) between 21 and 30 years were randomized to receive either flunitrazepam 1 mg or placebo (both administered once a day in the evening) for 4 weeks in two cross-over periods; each separated by a 2-week placebo period. At the end of each study period, non-invasive 24-h BP and HR ambulatory monitoring was performed.
Results
Flunitrazepam produced a significant decrease in nighttime systolic blood pressure (SBP) (− 6.4 mmHg) and diastolic blood pressure (DBP) (− 4.1 mmHg) (both
P
< 0.05 vs placebo) without affecting nocturnal HR. During the morning hours, significantly higher values of SBP (+ 7.4 mmHg,
P
< 0.01), DBP (+ 3.4 mmHg,
P
< 0.05) and HR (+ 3.9 beats/min,
P
< 0.05) were observed in the flunitrazepam group compared to the placebo-treated group. No significant differences were noted between the two groups during afternoon and evening hours.
Conclusions
These results suggest that chronic oral administration of 1 mg flunitrazepam as a hypnotic agent causes a significant nocturnal fall in BP and a transient rebound increase of both BP and HR at awakening in the morning. Mechanisms underlying these cardiovascular effects remain unclear, although the direct vasodilatory effect, which is typical of flunitrazepam (with consequent reflex counter-regulatory responses), and the attenuation of baroreflex sensitivity are likely to play a major role.
To investigate the potential contributions of diastolic and systolic blood pressure (BP) and the circadian rhythm of BP to chronic migraine evolution.
This cross-sectional study included four groups ...of patients selected based on migraine frequency (high frequency ≥ 10 days per month and low frequency < 10) and on the presence of hypertension. Among-group and pairwise comparisons were carried out to investigate potential neurophysiologic differences in the cerebral vessel reactivity to a nitroglycerin test, in autonomic balance (tilting test), and BP circadian rhythm.
A more marked decrease in cerebral blood flow velocity was observed in hypertensive high-frequency migraineurs compared to all other groups (P = .037). Moreover, a smaller decrease in vagal tone was recorded in the orthostatic position in hypertensive subjects, whether they were high- (P = .032) or low-frequency migraineurs (P = .014), with a consistently higher vagal to sympathetic tone ratio (P = .033). Finally, in nonhypertensive subjects, a higher but not significant prevalence of systolic nondippers was detected in high-frequency migraineurs (67%) compared to low-frequency subjects (25%; P = .099).
These findings suggest that hypertension may contribute to the chronic evolution of headache with mechanisms shared with migraine; ie, vascular tone alteration and autonomic dysregulation.
Purpose
The aim of this study was to evaluate the relationship between orthostatic hypotension (OH), defined as a decrease in systolic blood pressure (SBP) ≥20 mmHg and/or a decrease in diastolic ...blood pressure (DBP) ≥10 mmHg, and 24-h ambulatory BP profile in elderly hypertensive type 2 diabetic patients.
Methods
After a 2-week antihypertensive wash-out period, 200 hypertensive well-controlled diabetic outpatients, aged 65–75 years, underwent a clinical examination, including BP measurements, ECG, 24-h ABP monitoring (ABPM), an orthostatic test, and three tests for cardiovascular autonomic function assessment deep breathing, heart rate (HR) variability, resting HR.
Results
According to their nighttime BP profile, patients were divided into three groups: dippers (
n
= 86) (BP fall during nighttime ≥10 %), non-dippers (
n
= 80) (BP fall during nighttime 0–10 %), and reverse dippers (
n
= 34) (nighttime BP > daytime BP). Orthostatic test produced a significantly greater orthostatic SBP fall in dippers and even more in reverse dippers. In these latter, a significant fall was observed also in DBP. Prevalence of OH was 9.3 % in dippers, 30 % in non-dippers, and 79.4 % in reverse dippers.
Conclusions
In elderly hypertensive type 2 diabetics, a blunted nocturnal BP fall is associated with OH and autonomic dysfunction. These data suggest that ABPM should be performed in the assessment of hypertensive diabetic patients in whom the cardiovascular dysautonomia is suspected or the signs of it are present (such as OH).
