Authors: Jalali Niloofar , Tran N Ken , Sen Anindya , Morita Plinio Pelegrini 
Published: January 2022

Background
The spread of COVID-19 at the local level is significantly impacted by population mobility. The U.S. has had extremely high per capita COVID-19 case and death rates. Efficient nonpharmaceutical interventions to control the spread of COVID-19 depend on our understanding of the determinants of public mobility.

Objective
This study used publicly available Google data and machine learning to investigate population mobility across a sample of US counties. Statistical analysis was used to examine the socioeconomic, demographic, and political determinants of mobility and the corresponding patterns of per capita COVID-19 case and death rates.

Methods
Daily Google population mobility data for 1085 US counties from March 1 to December 31, 2020, were clustered based on differences in mobility patterns using K-means clustering methods. Social mobility indicators (retail, grocery and pharmacy, workplace, and residence) were compared across clusters. Statistical differences in socioeconomic, demographic, and political variables between clusters were explored to identify determinants of mobility. Clusters were matched with daily per capita COVID-19 cases and deaths.

Results
Our results grouped US counties into 4 Google mobility clusters. Clusters with more population mobility had a higher percentage of the population aged 65 years and over, a greater population share of Whites with less than high school and college education, a larger percentage of the population with less than a college education, a lower percentage of the population using public transit to work, and a smaller share of voters who voted for Clinton during the 2016 presidential election. Furthermore, clusters with greater population mobility experienced a sharp increase in per capita COVID-19 case and death rates from November to December 2020.

Conclusions
Republican-leaning counties that are characterized by certain demographic characteristics had higher increases in social mobility and ultimately experienced a more significant incidence of COVID-19 during the latter part of 2020.
Perceptions and Needs of Artificial Intelligence in Health Care to Increase Adoption: Scoping Review
Authors: Chew Han Shi Jocelyn , Achananuparp Palakorn 
Published: January 2022

Background
Artificial intelligence (AI) has the potential to improve the efficiency and effectiveness of health care service delivery. However, the perceptions and needs of such systems remain elusive, hindering efforts to promote AI adoption in health care.

Objective
This study aims to provide an overview of the perceptions and needs of AI to increase its adoption in health care.

Methods
A systematic scoping review was conducted according to the 5-stage framework by Arksey and O’Malley. Articles that described the perceptions and needs of AI in health care were searched across nine databases: ACM Library, CINAHL, Cochrane Central, Embase, IEEE Xplore, PsycINFO, PubMed, Scopus, and Web of Science for studies that were published from inception until June 21, 2021. Articles that were not specific to AI, not research studies, and not written in English were omitted.

Results
Of the 3666 articles retrieved, 26 (0.71%) were eligible and included in this review. The mean age of the participants ranged from 30 to 72.6 years, the proportion of men ranged from 0% to 73.4%, and the sample sizes for primary studies ranged from 11 to 2780. The perceptions and needs of various populations in the use of AI were identified for general, primary, and community health care; chronic diseases self-management and self-diagnosis; mental health; and diagnostic procedures. The use of AI was perceived to be positive because of its availability, ease of use, and potential to improve efficiency and reduce the cost of health care service delivery. However, concerns were raised regarding the lack of trust in data privacy, patient safety, technological maturity, and the possibility of full automation. Suggestions for improving the adoption of AI in health care were highlighted: enhancing personalization and customizability; enhancing empathy and personification of AI-enabled chatbots and avatars; enhancing user experience, design, and interconnectedness with other devices; and educating the public on AI capabilities. Several corresponding mitigation strategies were also identified in this study.

Conclusions
The perceptions and needs of AI in its use in health care are crucial in improving its adoption by various stakeholders. Future studies and implementations should consider the points highlighted in this study to enhance the acceptability and adoption of AI in health care. This would facilitate an increase in the effectiveness and efficiency of health care service delivery to improve patient outcomes and satisfaction.
Investigating #covidnurse Messages on TikTok: Descriptive Study
Authors: Yalamanchili Bhavya , Donelle Lorie , Jurado Leo-Felix , Fera Joseph , Basch Corey H 
Published: January 2022

Background
During a time of high stress and decreased social interaction, nurses have turned to social media platforms like TikTok as an outlet for expression, entertainment, and communication.

Objective
The purpose of this cross-sectional content analysis study is to describe the content of videos with the hashtag #covidnurse on TikTok, which included 100 videos in the English language.

Methods
At the time of the study, this hashtag had 116.9 million views. Each video was coded for content-related to what nurses encountered and were feeling during the COVID-19 pandemic.

Results
Combined, the 100 videos sampled received 47,056,700 views; 76,856 comments; and 5,996,676 likes. There were 4 content categories that appeared in a majority (>50) of the videos: 83 showed the individual as a nurse, 72 showed the individual in professional attire, 58 mentioned/suggested stress, 55 used music, and 53 mentioned/suggested frustration. Those that mentioned stress and those that mentioned frustration received less than 50% of the total views (n=21,726,800, 46.17% and n=16,326,300, 34.69%, respectively). Although not a majority, 49 of the 100 videos mentioned the importance of nursing. These videos garnered 37.41% (n=17,606,000) of the total views, 34.82% (n=26,759) of the total comments, and 23.85% (n=1,430,213) of the total likes. So, despite nearly half of the total videos mentioning how important nurses are, these videos received less than half of the total views, comments, and likes.

Conclusions
Social media and increasingly video-related online messaging such as TikTok are important platforms for social networking, social support, entertainment, and education on diverse topics, including health in general and COVID-19 specifically. This presents an opportunity for future research to assess the utility of the TikTok platform for meaningful engagement and health communication on important public health issues.

Women are creatures who have been assumed as the second-class citizens or only engaged in domestic activities. It arises because of the feminine nature that has been attached to women. However, as time goes by, the rules and values ​​of women have changed. The emancipation movements appear to bring women to work in the economic sector to take multiple roles. The purpose of this research is to find out how the actions of housewives in running dual roles.
This research uses qualitative approach with descriptive method. Qualitative descriptive is a method in examining the status of a group of people, an object, a set of conditions, a system of thought or a class. The subject of this study as many as ten people. Informant determination technique in this research conducted by purposive sampling technique, the informants are selected based on the characteristics or the predetermined character. Data analysis techniques used are data collection, data reduction, data presentation, conclusion and data verification.
The theory used to analyze this research is Talcott Parsons' voluntaristic action theory, in which a person performs a certain purpose of action. In addition, the aim is achieved by referring to the values ​​and norms, using the tools and means as capital goals by looking at the conditions and circumstances around it.
The results showed that the purpose of housewives performing dual role acts is to improve the family economy as well as the form of self-actualization as a wife, mother a nd a worker. Then, in order to achieve these goals, housewives perform a dual role as home workers, while upholding the values ​​and norms, using the tools and facilities owned, and still pay attention to the conditions and situation surrounding her.

Published: January 2022

SUMMARY

Objectives
To systematically review the literature on color stability of resin-based composites (RBC) after in vitro bleaching protocols and to assess the influence of bleaching protocols by meta-regression analysis on RBC color stability, and the association with clinical and experimental characteristics.

Methods
The electronic search was conducted in MEDLINE/PubMed, Scopus, and Web of Science databases and included English language studies that evaluated and reported color differences (CIELAB values) of RBC after in vitro bleaching procedures using hydrogen peroxide and/or carbamide peroxide.

Results
Database search for color change of RBC after bleaching retrieved 1335 eligible papers after removing duplicates. After initial screening, 66 articles were assessed for full-text reading with final inclusion of 23 published papers. A meta-regression analysis showed that storage time (p≤0.01), color measuring device (p≤0.01), and background color (p≤0.01) had influenced on color changes of RBC. The bleaching protocol (bleaching agent and time of application) did not influence on color changes of RBC (p&gt;0.01).

Conclusions
There is evidence that RBC change color after bleaching, but the change is not clinically significant.

Authors: Gao J , Jia L , Tan X , Yu H 
Published: January 2022

SUMMARY

Objective
This in vitro study aimed to evaluate the preservation of enamel after tooth preparation for porcelain laminate veneers (PLVs) at different preparation depths based on a fully digital workflow.

Methods and Materials
Sixty extracted human maxillary anterior teeth, including 20 maxillary central incisors (MCIs), 20 maxillary lateral incisors (MLIs), and 20 maxillary canines (MCs) underwent microcomputed tomography (CT) scanning, and were reconstructed as three-dimensional (3D) enamel and dentin models. Subsequently, the three-dimensional (3D) enamel models were imported into Materialise, where each enamel model underwent seven types of virtual preparation for PLVs at preparation depths at 0.1-mm increments from 0.1-0.3-0.5 mm (D1) to 0.7-0.9-1.1 mm (D7). The enamel surface was depicted by merging the virtual preparation and, respective, dentin models. The enamel area and prepared surface were measured to calculate the percentage of enamel (R%). The data were statistically analyzed using one-way analysis of variance (ANOVA) (α=0.05).

Results
The group-wise mean (standard deviation) R values for the MCIs were as follows: D1-D3: 100.00 (0) each, and D4–D7: 74.70 (2.45), 51.40 (5.12), 24.40 (3.06), and 0.00 (0), respectively. The group-wise mean R values for the MLIs were 100.00 (0), 73.70 (3.40), 53.50 (3.44), 25.20 (3.79), and 0.90 (0.99) for the D1–D5 groups, respectively; and 0.00 (0) each for the D6–D7 groups. The group-wise mean (standard deviations) R values for the MCs were as follows: D1–D3: 100.00 (0) each, and D4–D7: 99.00 (1.34), 77.10 (3.28), 74.20 (3.61), and 52.20 (4.09), respectively. The one-way ANOVA revealed significant differences between the seven groups in the MCIs, MLIs, and MCs (p&lt;0.05).

Conclusions
Our results recommended preparation depths of up to 0.3-0.5-0.7 mm (MCIs), 0.1-0.3-0.5 mm (MLIs), and 0.4-0.6-0.8 mm (MCs) to facilitate complete intraenamel preparation. Moreover, 50% enamel was preserved at preparation depths of 0.5-0.7-0.9 mm (MCIs), 0.3-0.5-0.7 mm (MLIs), and 0.7-0.9-1.1 mm (MCs).
Quand les sciences sociales s’intéressent à la technologie : un état des lieux bibliographique des recherches sur la Smart city
Authors: Wahyuddin Yasser , Bardet Fabrice 
Published: January 2022

Les villes intelligentes, souvent habillées d’ailleurs dans la langue des GAFA, en Smart Cties, font l’objet de travaux scientifiques très nombreux, depuis plus d’une décennie maintenant. Une abondance qui témoigne sans doute du statut dont dispose aujourd’hui cette idée à l’échelle de la planète : la ville intelligente est la dernière-née des utopies urbaines qui accompagnent de longue date le développement des sociétés. Une revue de la littérature consacrée à cet objet apparaît donc d’emblée une gageure. De manière liée, c’est aussi la diversité des disciplines académiques qui se passionnent pour la Smart City qui rend l’exercice délicat. Ces disciplines sont aussi nombreuses qu’éloignées, depuis les sciences les plus fondamentales, hautement mathématisées, en lien avec les modélisations des phénomènes urbains, jusqu’aux sciences sociales les plus descriptives, nourrie par une perspective ethnographique par exemple, en passant par les sciences économiques ou celles de l’aménagement des territoires, souvent liées à l’activité des gestionnaires. C’est dans ce contexte que nous avons considéré que la perspective des études urbaines critiques, qui revendique à la fois l’interdisciplinarité et le rapport réflexif avec le champ de l’action publique, constituait la porte d’entrée efficace pour tenter d’y voir clair dans cette jungle qu’est devenue la littérature scientifique consacrée à la Smart City.

Abstract

OBJECTIVE
To determine the pharmacokinetics and potential adverse effects of pimobendan after oral administration in New Zealand White rabbits (Ocytolagus cuniculi).

ANIMALS
10 adult sexually intact (5 males and 5 females) rabbits.

PROCEDURES
2 pilot studies were performed with a pimobendan suspension or oral tablets. Eight rabbits received 7.5 mg of pimobendan (mean 2.08 mg/kg) suspended in a critical care feeding formula. Plasma concentrations of pimobendan and O-demethylpimobendan (ODMP) were measured, and pharmacokinetic parameters were calculated for pimobendan by noncompartmental analysis. Body weight, food and water consumption, mentation, urine, and fecal output were monitored.

RESULTS
Mean ± SD maximum concentration following pimobendan administration was 15.7 ± 7.54 ng/mL and was detected at 2.79 ± 1.25 hours. The half-life was 3.54 ± 1.32 hours. Plasma concentrations of pimobendan were detectable for up to 24 hours. The active metabolite, ODMP, was detected in rabbits for 24 to 36 hours. An adverse event occurred following administration of pimobendan in tablet form in 1 pilot study, resulting in death secondary to aspiration. No other adverse events occurred.

CLINICAL RELEVANCE
Plasma concentrations of pimobendan were lower than previously reported for dogs and cats, despite administration of higher doses, and had longer time to maximum concentration and half-life. Based on this study, 2 mg/kg of pimobendan in a critical care feeding formulation should maintain above a target plasma concentration for 12 to 24 hours. However, further studies evaluating multiple-dose administration as well as pharmacodynamic studies and clinical trials in rabbits with congestive heart failure are needed to determine accurate dose and frequency recommendations.
Two case reports of umbilical metastasis: the enigmatic Sister Mary Joseph nodule
Authors: Ramael Maaike , Poels Helene , Steelandt Hilde Van , Develter Wim , Ramael Marc 
Published: January 2022

Background:
Umbilical metastasis, also known as Sister Mary Joseph nodule, is a rare pathognomonic clinical sign suggesting the presence of an internal cancer.

Case Presentation:
We describe two female patients with Sister Mary Joseph nodule. In one case, there was a relapse of cancer. In the other patient, the Sister Mary Joseph nodule was the first and only clinical sign of an abdominal malignancy. We will briefly discuss the association with various internal malignancies as well as the pathogenesis and differential diagnosis.

Conclusion:
We conclude that Sister Mary Joseph nodule is a sign of intra-abdominal malignancy most frequently associated with gastro-intestinal or gynecological cancer.
It can be the first and only clinical sign of abdominal malignancy in an otherwise healthy appearing patient or it can be an indication of oncological progressive disease, tumor relapse.
Umbilical lesions should raise suspicion of a Sister Mary Joseph nodule, but a differential diagnosis must be made with other primary umbilical malignancies as well as with benign conditions involving the umbilicus.
Efecto del azufre y Saccharomyces cerevisiae en la dieta de vacas lecheras como repelente de garrapatas en la comunidad El Regadío-Estelí, 2019
Authors: Moreno Castellón Medardo De Jesús 
Published: January 2022

El presente trabajo se llevó a cabo en la comunidad el Regadío - Estelí, donde se evaluó el efecto del azufre y la levadura de cerveza (Saccharomyces cerevisiae) en la dieta de vacas lecheras como repelente de garrapatas, siendo las variables de estudio, identificación de garrapatas, efectividad de los tratamientos, producción lechera y relación beneficio/costo. Para el estudio se utilizó un diseño de bloque completamente al azar (BCA), el estudio estuvo constituido por tres tratamientos (T1: Testigo, T2: 8% de inclusión de azufre, T3: inclusión de levadura de cerveza) con tres repeticiones cada uno para un total de nueve unidades experimentales. Los resultados obtenidos fueron: Las garrapatas que estaban con mayor presencia dentro del hato lechero fueron los géneros Amblyomma cajennense en un 70% y Boophilus microplus con un 30%. La efectividad del azufre sobre la repelencia de garrapatas en los animales en estudio fue del 96%, mostrando diferencia significativa en comparación con el tratamiento a base de levadura de cerveza y el tratamiento testigo. En el caso de la variable producción lechera no existió diferencia significativa entre los tratamientos evaluados sin mostrar repercusión sobre la producción; sin embargo luego de realizar los análisis de rentabilidad, el suministro de azufre en la dieta de vacas lecheras tuvo un costo de 0.8 córdobas día/animal, reduciendo gastos en control de garrapatas en comparación con otras prácticas de manejo de garrapatas; por lo tanto el suministro de azufre en la dieta es una alternativa viable para el control de garrapatas en vacas lecheras sin afectar su productividad.
