Aerial Systems

Unmanned Aerial Systems (UASs) have rapidly been integrated into the construction industry over the past few years, and their application is continually growing in this domain. The recent development in UAS regulations and technical capabilities have played a significant role in their popularity and wide deployment in various stages of the construction lifecycle. UASs could be used as a platform to enhance the construction practices in general; however, little is known about how construction professionals are adopting this technology in specific construction practices and the barriers they are facing for their successful implementation. The purpose of this study is to explore the current state-of-practice of UAS integration in construction from the industry professionals’ viewpoint. A comprehensive survey study was conducted in the United States to identify the practical construction UAS application areas, their adopted technologies, as well as the benefits and barriers encountered during their implementation. Responses (n=56) showed that most common UAS applications include progress monitoring, site planning, and site surveying/mapping. Rotary-wing vehicles and visual and thermal cameras were the most used platforms and onboard sensors, respectively. Saving time, improving accessibility to compromised spaces, and reducing cost while accomplishing construction tasks were highly regarded as UAS implementation benefits in construction. Participants also considered flying in various weather conditions, within confined or congested areas, as well as the advanced technical know-how requirements, and the increased liability and legal challenges as barriers to using UASs in construction-related tasks. By understanding UAS adoption in construction, this study provides a roadmap to better identify the industry needs and guide researchers and professionals in investigating application areas and barriers that might have maximum benefits for the construction industry in the United States.

BACKGROUND Asthma is a chronic lung disease that affects nearly 25 million individuals in the United States. There is a need for more research into the potential for health care providers to leverage existing social media platforms to improve healthy behaviors and support individuals living with chronic health conditions. OBJECTIVE In this study, we assess the willingness of Instagram users with poorly controlled asthma to participate in a pilot study that uses Instagram as a means of providing social and informational support. In addition, we explore the potential for adapting photovoice and digital storytelling to social media. METHODS A survey study of Instagram users living with asthma in the United States, between the ages of 18 to 40. RESULTS Over 3 weeks of recruitment, 457 individuals completed the pre-survey screener; 347 were excluded. Of the 110 people who were eligible and agreed to participate in the study, 82 completed the study survey. Respondents mean age was 21(SD = 5.3). Respondents were 56% female (n=46), 65% (n=53) non-Hispanic white, and 72% (n=59) had at least some college education. The majority of respondents (n = 66, 81%) indicated that they would be willing to participate in the study. CONCLUSIONS Among young-adult Instagram users with asthma there is substantial interest in participating in a study that uses Instagram to connect participants with peers and a health coach in order to share information about self-management of asthma and build social connection.

Abstract Disclaimer In an effort to expedite the publication of articles related to the COVID-19 pandemic, AJHP is posting these manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. Purpose To provide an overview of the impact of pharmacist interventions on antibiotic prescribing and the resultant clinical outcomes in an outpatient antibiotic stewardship program (ASP) in the United States. Methods Reports on studies of pharmacist-led ASP interventions implemented in US outpatient settings published from January 2000 to November 2020 and indexed in PubMed or Google Scholar were included. Additionally, studies documented at the ClinicalTrials.gov website were evaluated. Study selection was based on predetermined inclusion criteria; only randomized controlled trials, observational studies, nonrandomized controlled trials, and case-control studies conducted in outpatient settings in the United States were included. The primary outcome was the observed differences in antibiotic prescribing or clinical benefits between pharmacist-led ASP interventions and usual care. Results Of the 196 studies retrieved for full-text review, a cumulative total of 15 studies were included for final evaluation. Upon analysis, we observed that there was no consistent methodology in the implementation of ASPs and, in most cases, the outcome of interest varied. Nonetheless, there was a trend toward improvement in antibiotic prescribing with pharmacist interventions in ASPs compared with that under usual care (P < 0.05). However, the results of these studies are not easily generalizable. Conclusion Our findings suggest a need for a consistent approach for the practical application of outpatient pharmacist-led ASPs. Managed care organizations could play a significant role in ensuring the successful implementation of pharmacist-led ASPs in outpatient settings.

Over Time

Since COVID-19 transmission accelerated in the United States in March 2020, guidelines have recommended that individuals wear masks and limit close contact by remaining at least six feet away from others, even while outdoors. Such behavior is important to help slow the spread of the global pandemic; however, it may require pedestrians to make critical decisions about entering a roadway in order to avoid others, potentially creating hazardous situations for both themselves and for drivers. In this survey study, we found that while overall patterns of self-reported pedestrian activity remained largely consistent over time, participants indicated increased willingness to enter active roadways when encountering unmasked pedestrians since the COVID-19 pandemic began. Participants also rated the risks of encountering unmasked pedestrians as greater than those associated with entering a street, though the perceived risk of passing an unmasked pedestrian on the sidewalk decreased over time.

Background. Endoscopy nurse (RN) has a pivotal role in administration and monitoring of moderate sedation during endoscopic procedures. When sedation for the procedure is administered and monitored by an anesthesia specialist, the role of an RN is less clear. The guidelines on this issue by nursing and gastroenterology societies are contradictory. Methods. Survey study of endoscopy lab managers and directors at outpatient endoscopy units in Texas. The questions related to staffing patterns for outpatient endoscopies and responsibilities of different personnel assisting with endoscopies. Results. Responses were received from 65 endoscopy units (response rate 38%). 63/65 (97%) performed at least a few cases with an anesthesia specialist. Of these, 49/63 (78%) involved only an endoscopy technician, without an additional RN in the room. At 12/49 (25%) units, the RN performed tasks of an endoscopy technician. At 14/63 (22%), an additional RN was present during endoscopic procedures and performed tasks not directly related to patient care. Conclusions. Many ambulatory endoscopy units do not have an RN present at all times when sedation is administered by an anesthesia specialist. An RN, when present, did not perform tasks commensurate with the education and training. This has implications about optimal utilization of nurses and cost of performing endoscopies.

Drosophila suzukii, or spotted-wing drosophila, is now an established pest in many parts of the world, causing significant damage to numerous fruit crop industries. Native to East Asia, D. suzukii infestations started in the United States a decade ago, occupying a wide range of climates. To better understand invasion ecology of this pest, knowledge of past migration events, population structure, and genetic diversity is needed. To improve on previous studies examining genetic structure of D. suzukii, we sequenced whole genomes of 237 individual flies collected across the continental U.S., as well as several representative sites in Europe, Brazil, and Asia, to identify hundreds of thousands of genetic markers for analysis. We analyzed these markers to detect population structure, to reconstruct migration events, and to estimate genetic diversity and differentiation within and among the continents. We observed strong population structure between West and East Coast populations in the U.S., but no evidence of any population structure North to South, suggesting there is no broad-scale adaptations occurring in response to the large differences in regional weather conditions. We also find evidence of repeated migration events from Asia into North America have provided increased levels of genetic diversity, which does not appear to be the case for Brazil or Europe. This large genomic dataset will spur future research into genomic adaptations underlying D. suzukii pest activity and development of novel control methods for this agricultural pest.

The study and generalization of foreign experience is a value for Ukraine, which has set itself the task of integration into the world community and can be an important source of thorough thinking and creative use of positive ideas in domestic theory and practice of physical education and sports. This article analyzes the content and features of the organization of intramural (in-school) sports in the United States. The study found that intramural sports in the United States are an integral part of the overall education program, which provides an opportunity to involve children with different levels of development of motor skills and qualities in motor activities outside of physical education lessons. Participation in intramural sports programs is voluntary. It is determined that the intramural sports program in the United States is characterized by certain features that must be taken into account for its successful implementation. It was found that, first of all, American specialists determine the direction (nature) of the sports program and possible types of physical activity, taking into account the wishes of students; it is important to properly plan and compile a quality schedule for classes in compliance with the capacity of existing sports facilities; it is obligatory to observe the rules of admission of students to classes and competitions, as well as their annual medical examination; implementation of the sports program is carried out with the use of modern information technologies; the accounting and evaluation of the program is constantly carried out; proper administration and quality arbitration are of great importance; special attention is paid to the competition procedure itself and the determination of winners; a special place is given to the financing of programs and their support and promotion.

Karnal bunt of wheat (caused by Tilletia indica) was first detected in the United States in Arizona in 1996. The seed lots of infected, spring-habit, durum wheat associated with the initial detection were traced to planted fields in California, Arizona, New Mexico, and Texas. However, in the summer of 1997, the disease appeared in unrelated, winter-habit, bread wheat located over 700 km from the nearest potentially contaminated wheat from 1996 (and destroyed prior to reinfection). Here, we examined potential invasion pathways of the fungus associated with the movement of wheat into the United States. We analyzed the USDA/APHIS Port Information Network (PIN) database from 1984 through 2000 to determine likely pathways of introduction based on where, when, and how the disease was intercepted coming into the United States. All interceptions were made on wheat transported from Mexico, with the majority (98.8%) being intercepted at land border crossings. Karnal bunt was not intercepted from any other country over the 17-year period analyzed. Most interceptions were on wheat found in automobiles, trucks, and railway cars. The majority of interceptions were made at Laredo, Brownsville, Eagle Pass, and El Paso, TX, and Nogales, AZ. Karnal bunt was intercepted in all 17 years; however, interceptions peaked in 1986 and 1987. Averaged over all years, more interceptions (19.2%) were made in the month of May than in any other month. Our results indicate that Karnal bunt has probably arrived in the United States on many occasions, at least since 1984. Because of the relatively unaggressive nature of the disease and its reliance on rather exacting weather conditions for infection, we surmised that it is possible this disease has a long period of latent survival between initial arrival and becoming a thriving, established disease.
