Digital Approaches to Music-Making for People With Dementia in Response to the COVID-19 Pandemic: Current Practice and Recommendations.

Before COVID-19, dementia singing groups and choirs flourished, providing activity, cognitive stimulation, and social support for thousands of people with dementia in the UK. Interactive music provides one of the most effective psychosocial interventions for people with dementia; it can allay agitation and promote wellbeing. Since COVID-19 has halted the delivery of in-person musical activities, it is important for the welfare of people with dementia and their carers to investigate what alternatives to live music making exist, how these alternatives are delivered and how their accessibility can be expanded. This community case study examines recent practice in online music-making in response to COVID-19 restrictions for people with dementia and their supporters, focusing on a UK context. It documents current opportunities for digital music making, and assesses the barriers and facilitators to their delivery and accessibility. Online searches of video streaming sites and social media documented what music activities were available. Expert practitioners and providers collaborated on this study and supplied input about the sessions they had been delivering, the technological challenges and solutions they had found, and the responses of the participants. Recommendations for best practice were developed and refined in consultation with these collaborators. Over 50 examples of online music activities were identified. In addition to the challenges of digital inclusion and accessibility for some older people, delivering live music online has unique challenges due to audio latency and sound quality. It is necessary to adapt the session to the technology's limitations rather than expect to overcome these challenges. The recommendations highlight the importance of accessibility, digital safety and wellbeing of participants. They also suggest ways to optimize the quality of their musical experience. The pandemic has prompted innovative approaches to deliver activities and interventions in a digital format, and people with dementia and their carers have adapted rapidly. While online music is meeting a clear current need for social connection and cognitive stimulation, it also offers some advantages which remain relevant after COVID-19 restrictions are relaxed. The recommendations of this study are intended to be useful to musicians, dementia care practitioners, and researchers during the pandemic and beyond.

Diagnostic imaging and spending review: extreme problems call for extreme measures.

The number of diagnostic imaging tests has increased dramatically over the past decade and about 5 billion diagnostic examinations are performed worldwide each year. According to Health Ministry, Italy, is in second place for the number of CT and MR tests per thousand inhabitants in 2014 with a score of 83.3 (only Germany has a higher score, 95.2) that is a long way off from the European average of 46.5. It has also the highest ratio of magnetic resonances per person with 24,6 machines per million inhabitants, followed only by Greece and Finland. The development of the New Health Information System (NSIS) in 2010 made uniformly readable the non-homogeneous clinical data from all the different Italian regions and permitted a detailed analysis of all diagnostic imaging within the public outpatient care setting in Italy in 2012. Despite that MRI examinations represented only the 10% of the total number of imaging tests performed, their cost reached 30% of the health-care expenditure for outpatient diagnostic imaging with an overwhelming contribution coming from musculoskeletal MR which accounted for the 73% of the performed MR tests. It is reasonable to assume that these phenomena are likely due to a lack of appropriateness in MR requests that is difficult to analyze due to an absence or invalid query on the prescriptions which together accounted for the 98.7% of cases. Taking into account the above-mentioned situation, this is possibly why the Ministry of Health decided to perform "linear cuts" in expenditure for some diagnostic examinations.

Spinal hydatidosis relapse: a case report.

Human cystic echinococcosis (CE) is a zoonosis caused by the larval stage of the Echinococcus granulosus and the most common sites affected are the liver and lung in approximately 80-90% of cases. The hydatid bone represents the 0.5-2.5% of all cases and localization cord is present about 50% of the time. This benign and commonly asymptomatic disease may simulate an aggressive malignancy because of osseous destruction and aggressive extension. We report a case of a 42-year-old male patient, presented with an unusual spinal hydatidosis relapse, related to anthelmintic drug therapy withdrawal after 10-year treatment. The man had previous excision of chest and hepatic hydatid cysts (resp., 10 and 3 years ago) and after primary mediastinal and spinal involvement (3 years ago) he was lost to follow-up and discontinued drug therapy. The patient underwent surgery and the postoperative histopathology confirmed the diagnosis. The patient recovered with no complications. Despite significant progress in diagnostic imaging, pharmacological and surgical therapy, spinal CE remains associated with high morbidity.

Value of strain-ratio on thyroid real-time sonoelastography.

PURPOSE: The aim of this study was to determine the accuracy of elastosonography in the differential diagnosis of thyroid nodules using a qualitative [evaluation of the stiffness score (SS)] and quantitative assessment [evaluation of the strain ratio (SR)]. MATERIALS AND METHODS: In our single-centre retrospective study, 368 patients were enroled between December 2010 and March 2012 (134 men, 234 women, mean age 56.1 ± 14.2) with a diagnosis of thyroid nodules, who underwent conventional ultrasonographic and elastosonographic evaluation. The SS and SR were assessed and the results were expressed in terms of sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). The nodules were subjected to needle aspiration. RESULTS: Forty-four nodules were malignant (TIR ≥ 3) and 324 benign on cytological analysis. Considering a cut-off of SS > 2, we had 91% sensitivity, 68% specificity, 27% PPV and 98% NPV. Considering a cut-off of SR ≥ 3.28, we had 81.8% sensitivity, 82.7% specificity, 39.1% PPV and 97.1% NPV. CONCLUSIONS: The SR calculation did not provide additional data to the SS, which remains the elastosonography benchmark. It will be necessary to validate these preliminary data by larger prospective randomised trials.

Hybrid SPECT/CT Imaging in the Evaluation of Coronary Stenosis: Role in Diabetic Patients.

Purpose. Our purpose was to combine the results of the MDCT (multidetector computed tomography) morphological data and the SPECT (single-photon emission computed tomography) data using hybrid imaging to overcome the limits of the MDCT in the evaluation of coronary stenosis in diabetic patients with large amount of calcium in the coronary arteries. Method and Materials. 120 diabetic patients underwent MDCT examination and SPECT examination. We evaluated 324 coronary arteries. After the examinations, we merged CT and SPECT images. Results. CT evaluation: 52 (32.8%) coronaries with stenosis ≥ 50%, 228 (70.4%) with stenosis < 50%, and 44 (13.6%) with a doubtful evaluation. SPECT evaluation: 80 (24.7%) areas with hypoperfusion, 232 (71.6%) with normal perfusion, and 12 (3.7%) with a doubtful evaluation. Of 324 coronary arteries and corresponding areas, the hybrid SPECT/CT evaluation showed 92 (28.4%) areas with hypoperfusion, and 232 (71.6%) with normal perfusion. Conclusion. Hybrid CT/SPECT imaging could be useful in the detection of significant coronary stenosis in patients with large amount of coronary calcifications.

Mayer-Rokitansky-Kuster-Hauser syndrome diagnosed by magnetic resonance imaging. Role of imaging to identify and evaluate the uncommon variation in development of the female genital tract.

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a spectrum of Müllerian duct anomalies characterized by congenital aplasia of the uterus and of the upper part (2/3) of the vagina, in young women presenting otherwise with normal endocrine status. The ovaries and fallopian tubes are present. It is one of the most common causes of primary amenorrhea and affects at least 1 out of 4500 women. Its penetrance varies, as does the involvement of other organ systems and itcan be isolated (type I) or associated with other malformations (type II). The MRKH syndrome usually remains undetected until the patient presents with primary amenorrhea despite normal development of secondary sexual characteristics, so imaging evaluation can demonstrate in one setting, non invasively, the anomalies in development of genital tract. We report a case of MRKH syndrome in a 16-year-old woman who presented with primary amenorrhea, stressing the role and benefit of imaging in the differential diagnosis.

Liver elasticity in NASH patients evaluated with real-time elastography (RTE).

Liver elasticity as assessed by real-time elastography (RTE) has been shown to be correlated to liver fibrosis in various chronic liver diseases. The aim of our study was to assess the RTE performance in the evaluation of liver fibrosis in nonalcoholic steatohepatitis (NASH), as well as the histopathologic variables determining the eventual discordance between the RTE-predicted and the biopsy-proven fibrosis. Fifty-two consecutive biopsy proven NASH patients and 20 controls were studied. Liver tissue elasticity measurements were performed using the Hitachi EUB-8500 sonographer and the EUP-L52 Linear (3-7 MHz) probe. RTE liver tissue mean elasticity (TME) values were calculated and correlated to the histologic fibrosis, activity and steatosis scores. A decrease in TME was observed with increasing fibrosis (r = -0.75). Similarly, TME varied together consistently with steatosis (r = -0.3). In contrast, TME did not show any correlation with the severity of inflammation. Multiple regression analysis showed that fibrosis was the only variable able to significantly (p < 0.0001) modify TME values. The diagnostic accuracy of TME measurement for F > 0 evaluated by AUC-ROC analysis was 0.86. The diagnostic accuracy of TME measurement for F ≥ 2 was 0.92. We suggest that RTE could be used as a complementary imaging method to evaluate liver fibrosis in NASH patients. Future studies of larger patient cohorts are necessary for the validation of the technique.
