Published: July 2020

<p class="abstract"><strong>Background:</strong> Adenoid cystic carcinoma (ACC) is a rare malignant tumour originating from minor salivary glands. It is known for perineural spread, local recurrences and distant metastasis. The minor salivary gland tumour represents 3% of all head and neck neoplasms, whereas ACC constitutes about 0.5% of all malignant salivary gland neoplasms. This study was done to evaluate the clinical presentation and histopathological findings of minor salivary gland tumour.</p><p class="abstract"><strong>Methods:</strong> This study was done in the department of ENT, Bangalore Medical College and Research Institute from May 2017 to July 2019. Of the 25 patients with minor salivary gland tumour, 10 patients with ACC were considered for the present study. A detailed clinical and histopathological evaluation was done. Results were documented and tabulated in excel sheet. </p><p class="abstract"><strong>Results:</strong> We analysed data of 25 (16 female, 9 male) patients in the age group of 30-60 years, of which 10 patients had adenoid cystic carcinoma of minor salivary gland tumour. The most frequent site of tumour occurrence was noted in the hard palate (6 patients), followed by retromolar trigone (2 patients), floor of mouth (1 patient) and tongue (1 patient). The histopathological pattern noted most commonly in our study: cribriform pattern (6 cases), tubular (1 case) and solid (3 cases).</p><p class="abstract"><strong>Conclusions:</strong> ACC of minor salivary glands is rare. The otorhinolaryngologist should bear this clinical entity in mind when encountered with a painless swelling over the hard palate. This would lead to an early diagnosis and prompt management in such patients.</p>

Conservative management of bilateral chronic protracted temporomandibular joint dislocation: a case report
Authors: . Paramjit , Pansotra Neetu 
Published: July 2020

<p>Temporomandibular joint (TMJ) dislocation is a condition in which the mandibular condyle is anteriorly displaced beyond the articular eminence, hence completely out of glenoid fossa which leaves the patient unable to close his/her mouth. Long standing TMJ dislocation persisting for more than a month are the most challenging to treat. The management varies widely, from closed reduction to complicated surgical procedures to reduce the dislocated condyle. Each case of dislocation presents with its own unique features. Since there are no standard rules or conventions for the ideal strategy in different circumstances till date, initial approach should be conservative, preserving surgical treatment for later if needed. This paper presents the experience of conservatively managing a case of long standing (one and half month old) TMJ dislocation under general anaesthesia with excellent outcome.</p><p> </p>
Policy Does Matter: Changing an Unchangeable Long‐Term Services System
Authors: Applebaum Robert , Nelson Matt , Straker Jane K. , Kennedy Katherine 
Published: July 2020

AbstractBecause long‐term services policy is largely driven by state decisions, this study examines the impact of state‐level changes on Ohio's long‐term services system. Using longitudinal data collected over twenty‐six years, this paper tracks system changes, showing that despite a continued and dramatic increase in Ohio's older population, nursing home (NH) use has declined. The paper also documents the growth of in‐home services, assisted living, and the increase in short‐term institutional care. Advances in state policy, along with industry changes, such as the expansion of private pay home care and assisted living, have resulted in a changed long‐term services and supports (LTSS) landscape. Driven by continued demographic changes and associated resource constraints, tomorrow's challenges will be even more difficult to address. The paper concludes with a discussion about how the system will need to be reformed to meet the challenges ahead.
Life in a world for all ages: From a utopic idea to reality
Authors: Ayalon Liat 
Published: July 2020

AbstractAgeism is defined as stereotypes, prejudice, and discrimination toward people because of their age. Although ageism can be directed toward both young and old and can be both positive and negative, this paper reviews the negative manifestations and consequences of ageism toward older adults in policy, politics, the urban environment, the healthcare system, and the individual‐intra‐psychic level. Obstacles to and opportunities for reducing and potentially eliminating ageism are discussed. This review is intended to instigate interest and motivation in researchers, policy stakeholders, and the general public to change the way we think, feel, and act in order to live in a world for all ages, in which old age is no longer seen as a burden or a barrier.

Published: July 2020

Abstract
Background: Partial or an entire deletion of SHANK3 are considered as major drivers in the Phelan McDermid syndrome, in which 75% of patients are diagnosed with autism spectrum disorder (ASD). During the recent years, there was an increasing interest in stem cell therapy in ASD, and specifically, mesenchymal stem cells (MSC). Moreover, it has been suggested that the therapeutic effect of the MSC is mediated mainly via the secretion of small extracellular-vesicle that contain important molecular information of the cell and are used for cell-to cell communication. Within the fraction of the extracellular-vesicles, exosomes were highlighted as the most effective ones to convey the therapeutic effect.Methods: Exosomes derived from MSC (MSC-exo) were purified, characterized and given via intranasal administration to Shank3B KO mice (in concentration of 107 particals/ml). Three weeks post treatment the mice were tested for behavioral scoring and their results were compared to control saline treated and to their wild type littermates. Results: Intranasal treatment with MSC-exo improves the social behavior deficit in multiple paradigms, increases vocalization and reduces repetitive behaviors. We also observed an increase of GABARB1 in the prefrontal cortex.Conclusions: Herein, we hypothesized that MSC-exo would have a direct beneficial effect on the behavioral autistic-like phenotype of the genetically modified Shank3B KO mice model of autism. Taken together, our data indicate that intranasal treatment with MSC-exo improves the core ASD-like deficits of this mouse model autism and therefore has the potential to treat ASD patients carrying the Shank3 mutation.
Physical therapy interventions for older people with vertigo, dizziness and balance disorders addressing mobility and participation: a systematic review
Authors: Regauer Verena , Seckler Eva , Müller Martin , Bauer Petra 
Published: July 2020

Abstract
Background: Vertigo, dizziness and balance disorders (VDB) are among the most relevant contributors to the burden of disability among older adults living in the community and associated with immobility, limitations of activities of daily living and decreased participation. The aim of this study was to identify the quality of evidence of physical therapy interventions that address mobility and participation in older patients with VDB and to characterize the used primary and secondary outcomes.Methods: A systematic search via MEDLINE (PubMed), Cochrane Library, CINAHL, PEDro, forward citation tracing and hand search was conducted initially in 11/2017 and updated in 7/2019. We included individual and cluster-randomized controlled trials and trials with quasi-experimental design, published between 2007 and 2017/2019 and including individuals ≥ 65 years with VDB. Physical therapy and related interventions were reviewed with no restrictions to outcome measurement. Screening of titles, abstracts and full texts, data extraction and critical appraisal was conducted by two independent researchers. The included studies were heterogeneous in terms of interventions and outcome measures. Therefore, a narrative synthesis was conducted.Results: A total of 20 randomized and 2 non-randomized controlled trials with 1,876 patients met the inclusion criteria. The included studies were heterogeneous in terms of complexity of interventions, outcome measures and methodological quality. Vestibular rehabilitation (VR) was examined in twelve studies, computer-assisted VR (CAVR) in five, Tai Chi as VR (TCVR) in three, canal repositioning manoeuvres (CRM) in one and manual therapy (MT) in one study. Mixed effects were found regarding body structure/function and activities/participation. Quality of life and/or falls were assessed, with no differences between groups. VR is with moderate quality of evidence superior to usual care to improve balance, mobility and symptoms.Conclusion: To treat older individuals with VDB, VR in any variation and in addition to CRMs seems to be effective. High-quality randomized trials need to be conducted to inform clinical decision making.Trial Registration: PROSPERO 2017 CRD42017080291.

Abstract
Objective: Coronavirus disease 2019 (COVID-19) is currently the most serious infectious disease in the world. An accurate diagnosis of this disease in the clinic is very important. This study aims to improve the differential ability of computed tomography (CT) to diagnose COVID-19 and other community-acquired pneumonias (CAPs) and evaluate the short-term prognosis of these patients. Methods: The clinical and imaging data of 165 COVID-19 and 118 CAP patients diagnosed in seven hospitals in Anhui Province, China from January 21 to February 28, 2020 were retrospectively analysed. The CT manifestations of the two groups were recorded and compared. A correlation analysis was used to examine the relationship between COVID-19 and age, size of lung lesions, number of involved lobes, and CT findings of patients. The factors that were helpful in diagnosing the two groups of patients were identified based on specificity and sensitivity. Results: The typical CT findings of COVID-19 are simple ground-glass opacities (GGO), GGO with consolidation or grid-like changes. The sensitivity and specificity of the combination of age, white blood cell count, and ground-glass opacity in the diagnosis of COVID-19 were 92.7% and 66.1%, respectively. Pulmonary consolidation, fibrous cords, and bronchial wall thickening were used as indicators to exclude COVID-19. The sensitivity and specificity of the combination of these findings were 78.0% and 63.6%, respectively. The follow-up results showed that 67.8% (112/165) of COVID-19 patients had abnormal changes in their lung parameters, and the severity of the pulmonary sequelae of patients over 60 years of age worsened with age.[A1] Conclusions: Age, white blood cell count and ground-glass opacity have high accuracy in the early diagnosis of COVID-19 and the differential diagnosis from CAP. Patients aged over 60 years with COVID-19 have a poor prognosis. This result provides certain significant guidance for the diagnosis and treatment of new coronavirus pneumonia.
Motivation factors affecting the job attitude of medical doctors and the organizational performance of public hospitals in Warsaw, Poland

Published: July 2020

Abstract
Background: This paper examines the relationship between selected motivation factors that affect the attitude to work among medical doctors at public hospitals and the organizational performance of hospitals .Methods: This study was based on World Health Organization questionnaires designed to estimate motivation factors according to Herzberg’s motivation theory and to measure the level of organizational performance of hospitals by using the McKinsey model . A survey was conducted among physicians (n=249) with either surgical (operative) or nonsurgical (conservative) specialty in 22 departments/units of general public hospitals in Warsaw, Poland. The relationship between the chosen job motivation factors and organizational effectiveness was determined using Spearman’s rank correlation. Furthermore, 95% confidence intervals were calculated. The independent samples t-test was used to confirm statistically significant differences between the independent groups. Normality of the data was tested by the Kolmogorov–Smirnov test.Results: The survey revealed that motivation factors related to “quality and style of supervision” have the highest effect on the organizational performance of hospitals (Spearman’s rank correlation coefficient = 0.490; p<0.001), whereas “performance feedback” has the lowest effect on organizational performance according to the surveyed healthcare professionals (54% of physicians). Conclusion: The principles of Individual Performance Review should be incorporated into strategies designed to improve the organizational performance of hospitals (with NHS serving as a potential role model) in order to establish specific rules on how to share performance feedback with individual physicians. The present study contributes to literature on human resource management in the healthcare sector and highlights the importance of nonfinancial aspects in improving the organizational performance of hospitals.
Alexander Calder’s Half-Circle, Quarter-Circle, and Sphere (1932):A Complex History of Repainting Unraveled
Authors: Pozzi Federica , Arslanoglu Julie , Nagy Eleonora 
Published: July 2020

Abstract
The Whitney Museum of American Art, New York, owns one of the largest motorized works made by the renowned American artist Alexander Calder, titled Half-Circle, Quarter-Circle, and Sphere. Created in 1932, and acquired by the Whitney in 1969, this seminal work was featured in an iconic exhibition held in 2017 and entitled Calder: Hypermobility. Prior to that, the object underwent a series of treatments in order to repair its main kinetic elements that had become compromised during its lifetime. While the work’s mechanism retained its creator’s ingenious engineering solutions, the motor, urethane belts, plug, and electrical wires turned out to be neither original, nor authentic to the period. The appearance of the piece had also been altered, as most surfaces displayed multiple layers of overpainting and, thus, did not deliver the proper gloss, hue, and texture. These observations prompted a first, comprehensive scientific study to investigate the stratigraphy of Calder’s painted surfaces on Half-Circle, Quarter-Circle, and Sphere, with the final goal to comprehend and restore its original appearance through careful removal of the overpaint. Non-invasive X-ray fluorescence (XRF) analysis was carried out to gain initial insight into the paints’ composition. After that, extensive microscopic sampling was performed to assess the possible presence of original layers below the repainting throughout the object’s surface. Cross sections were examined with optical microscopy and analyzed with Fourier-transform infrared (FTIR) and Raman spectroscopies, as well as scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM/EDS), in order to identify pigments, colorants, and extenders located in the various paint layers. Scrapings were also investigated with pyrolysis – gas chromatography / mass spectrometry (Py-GC/MS) for a detailed characterization of the binding media. Scientific analysis revealed, in selected white and red areas, up to eleven layers of overpaint composed of a wide array of modern materials, including pigments (titanium white in the form of tetragonal rutile and a variety of synthetic organic red pigments) and binders (alkyd or late formulations of enamels based on ortho-phthalic acid / phthalic anhydride, glycerol and pentaerythritol, polyvinyl acetate with various plasticizers, and acrylics). On the other hand, the identification of materials that were available in the early 1930s, such as zinc white, calcite, and gypsum, as well as traditional drying oil binders, supported the hypothesis that a layer of original paint may still be present in certain areas. In addition to shedding new light on the stratigraphy of Calder’s painted surfaces, this study informed the optimization of a treatment plan tailored for the safe removal of the overpaint to uncover the original layer, wherever present.
Predicting COVID-19 Pandemic in Saudi Arabia Using Modified Singular Spectrum Analysis
Authors: Alharbi Nader 
Published: July 2020

Abstract
This research presents a modified Singular Spectrum Analysis (SSA) approach for the analysis of COVID-19 in Saudi Arabia. We have proposed this approach and developed it in [1–3] for separability and grouping step in SSA, which plays an important role for reconstruction and forecasting in the SSA. The modified SSA mainly enables us to identify the number of the interpretable components required for separability, signal extraction and noise reduction. The approach was examined using different number of simulated and real data with different structures and signal to noise ratio. In this study we examine its capability in analysing COVID-19 data. Then, we use Vector SSA for predicting new data points and the peak of this pandemic. The results shows that the approach can be used as a promising one in decomposing and forecasting the daily cases of COVID-19 in Saudi Arabia.
