The University of California San Diego performance-based skills assessment: a useful tool to detect mild everyday functioning difficulties in HIV-infected patients with very good immunological condition

Everyday functioning (EF) impairment is frequent in people living with HIV (PLWH). Our aim was to better explore EF and its association with PLWH cognition, by administering both the IADL scale, the most common functional scale, and a new and ecologic multi-domain (communication and financial skills) tool to measure EF as the University of California San Diego (UCSD) Performance-Based Skills Assessment-Brief Version (UPSA-B). Eighty-five PLWH on cART with very good immunological condition and 23 age- and education-matched healthy controls (HC) were enrolled. PLWH underwent a standardized neuropsychological battery plus IADL, and cognitive impairment was defined according to Frascati criteria. Both groups underwent the UPSA-B. Only 6 subjects (7%) were affected by cognitive impairment (asymptomatic profile). While IADL score was at ceiling for all patients, the UPSA-B total score was significantly worse in PLWH when compared with HC [mean 82.1 (SD 9.3) vs 89.2 (SD 6.2); p < 0.001]. At communication subtest, PLWH group and HC were significantly different (p = 0.002), while no difference emerged at financial skills (p = 0.096). Higher score at UPSA-B was independently associated with better global cognitive performance (composite Z-score) (\u3b2 7.79; p < 0.001). Also considering each single cognitive domain, UPSA-B performance (both total and at subtests) confirmed the association with neurocognitive performance. In conclusion, UPSA-B seems to better discriminate EF impairment than IADL in PLWH, and it was associated with cognitive functions, also in the absence of symptomatic cognitive impairment. Thus, it appears a promising tool in the context of HIV infection to avoid misdiagnosis and to better detect also mild EF

Psychopathological profile in COVID-19 patients including healthcare workers: the implications

OBJECTIVE: The effects of COVID-19 seem to extend beyond the physical pain and is showing psychiatric implications as well. Moreover, psychopathological implications seem to last also after patients' discharge. Our goal is to investigate the psychological impact and psychopathological outcome of patients affected by COVID-19.PATIENTS AND METHODS: We have engaged 34 patients with COVID-19 conditions [eight of them were healthcare workers patients (HCW)] hospitalized at "Policlinico Gemelli Foundation" of Rome, Italy. All patients were evaluated through the Impact of Event Scale-Revised (IES-R) and the Symptom Checklist 90-R (SCL-90-R) first, during their hospitalization (baseline), and then, after 4 months from hospital discharge (follow-up), through phone interviews.RESULTS: At baseline, 82% of patients revealed from mild to severe psychological impact of COVID-19, according to the IES-R. At follow-up, the mean IES-R total score was significantly decreased (p<0.001) even if almost half (46.6%) of our cohort still showed it. HCW patients showed a significantly higher score than other patients at IES-R scale, both at baseline (p=0.005) and at follow-up (p<0.001). Moreover, at 4 months from discharge, they showed a significantly higher percentage of moderate and severe distress (p=0.015). In addition to this. at follow-up, our cohort of patients showed an increase of anxiety symptoms, even if not significant compared to baseline (46.7% vs. 35.3% respectively; p=1.000). and HCW patients suffered more sleep disorders (p=0.019) and anxiety symptoms (p=0.019) compared to other patients.CONCLUSIONS: We indicate the importance of assessing psychopathology of COVID-19 survivors, monitoring their changes over time, and providing psychological support to improve their psychological well-being

A multi-parametric wearable system to monitor neck movements and respiratory frequency of computer workers

Musculoskeletal disorders are the most common form of occupational ill-health. Neck pain is one of the most prevalent musculoskeletal disorders experienced by computer workers. Wrong postural habits and non-compliance of the workstation to ergonomics guidelines are the leading causes of neck pain. These factors may also alter respiratory functions. Health and safety interventions can reduce neck pain and, more generally, the symptoms of musculoskeletal disorders and reduce the consequent economic burden. In this work, a multi-parametric wearable system based on two fiber Bragg grating sensors is proposed for monitoring neck movements and breathing activity of computer workers. The sensing elements were positioned on the neck, in the frontal and sagittal planes, to monitor: (i) flexion-extension and axial rotation repetitions, and (ii) respiratory frequency. In this pilot study, five volunteers were enrolled and performed five repetitions of both flexion-extension and axial rotation, and ten breaths of both quite breathing and tachypnea. Results showed the good performances of the proposed system in monitoring the aforementioned parameters when compared to optical reference systems. The wearable system is able to well-match the trend in time of the neck movements (both flexion-extension and axial rotation) and to estimate mean and breath-by-breath respiratory frequency values with percentage errors ≤6.09% and ≤1.90%, during quiet breathing and tachypnea, respectively

Design and fabrication of a non-invasive, wireless system for monitoring needle insertion during epidural puncture

Over the last decades epidural analgesia has gathered research interest and broad clinical acceptance. In this procedure, the detection of the epidural space is pivotal to avoid major complications. Although, some systems for supporting the anaesthetist in the epidural space detection are commercially available, this difficult procedure is often performed without any support. In previous articles, our research group described a new approach for a non-invasive detection of the epidural space; the assessment of the system was also performed both on a spinal column simulator and in ex vivo animal model (small pig). The mentioned system is based on a Force Sensing Resistor (FSR) that monitors the load exerted by the anaesthesiologist on the syringe plunger during the procedure. The resistance of the sensor is transduced into a voltage by means of a Wheatstone bridge (WB), then it is amplified, finally it is collected by a remote laptop. When the needle reaches the epidural space, the load applied by the anaesthesiologist decreases, so the consequent change of the system output may be used for the detection of the entrance within this space. The previous version of the system communicates to the laptop via USB. In this article, we described a new version of the system which communicates to the laptop via wireless. This solution aims at facilitating the use of the system in clinical settings. After the description of the measuring system, its preliminary assessment in patients undergoing epidural puncture will be reported

Agar-Coated Fiber Bragg Grating Sensor for Relative Humidity Measurements: Influence of Coating Thickness and Polymer Concentration

The importance of humidity control is spreading through a broad spectrum of applications, from food and pharmaceutical industries to biomedical and chemical fields. During the last decades, the growing interest in fiber Bragg gratings (FBG) led to new approaches and applications for the humidity measurement by means of the deposition of hygroscopic materials on gratings. The influence of the coating material and its features such us coating thickness (tk) and concentration (wt%) on static and dynamic metrological properties have been investigated in this paper. In this paper, four agar-coated FBG sensors for humidity measurements have been fabricated, and the influence of tk and wt% on the sensors' sensitivity and response time has been experimentally assessed. Sensitivity increases with tk and wt%: for instance, at 1 wt% it was 0.0024 nm ·%- and 0.0052 nm · %- for tk = 87 μm and tk = 212 μm, respectively. Results showed that also the response time increased with tk and wt%: for instance, at 1 wt% it was 56.7 s and 107.6 s for tk = 87 μm and tk = 212 μm, respectively

Use of Long-Acting Therapies for HIV Care in Italy: Are People Living with HIV Prepared for Change? A Cross-Sectional Study

Two hundred two people living with HIV (PLWH) selected from outpatients at the Infectious Disease Institute, Fondazione Policlinico Universitario A. Gemelli IRCCS, in Rome (Italy) were consecutively enrolled from May to July 2021. We used an anonymous telephone questionnaire to investigate opinions of PLWH about combined antiretroviral (ARV) therapy and long-acting (LA) formulations of ARVs. All invited participants completed the questionnaire (100%). We found that most PLWH evaluated taking HIV pills for the rest of their life as a continuous, but undemanding commitment (61.4%; n = 124), although they were willing to stop the daily intake of HIV drugs (78.2%, n = 158). Moreover, most PLWH were unaware of the existence of LA therapies at the time of the investigation (60.4%, n = 122). Almost half the PLWH evaluated the need for injections in the hospital as an obstacle (51.4%, n = 104). Regarding the preference between monthly injections and taking pills everyday, most PLWH (68.8%, n = 139) stated that the injection was more advantageous than pills even if they had some pain/swelling at the injection site. The concern about LA therapy indicated most by PLWH was the possible lower efficacy of the drug (83.7%, n = 169). Regarding the possible benefits of LA therapy, those reported most by PLWH were feeling freer because they did not have to remember to take pills everyday (68,8%, n = 139). In conclusion, to date, PLWH in our cohort seem willing to accept LA therapy, but still show some concern about the efficacy of the new therapy and the obligation to come to the hospital to receive it. Thus, clinicians must take into account the needs of their patients and help them overcome their concerns to facilitate the transition to this new therapeutic modality.
