352. COVID-19 Not a Risk Factor of Alopecia Areata: Results of a National Cohort Study in South Korea

Field: Medicine (Health Sciences)

Abstract Background There have been approximately 158 million coronavirus disease 2019 (COVID-19) pandemic survivors worldwide by June 9, 2021. As a result, concerns about hair loss in COVID-19 patients have emerged among dermatologists. However, most of extant literature have limited implications by relying on cross-sectional studies with restricted study subjects without control group. Therefore, our study aims to investigate the risk of developing alopecia areata (AA) among COVID-19 patients in South Korea using adequate control based on national representative data. Methods We used the National Health Insurance Service (NHIS) COVID-19 cohort database, comprising COVID-19 patient and control group, all of whom were diagnosed from January 1, 2020 to June 4, 2020. Patients were defined as individuals who were confirmed as COVID-19 positive, regardless of disease severity. Controls were defined as whom confirmed as COVID-19 negative. People with a history of AA during the period 2015–2019 were excluded. The primary endpoint was a new diagnosis of AA (ICD-10-CM-Code: L63). Adjusted incidence rate ratio (IRR) of developing AA was estimated using log-link Poisson regression model based on incidence density of case and control group. The model adjusted for (1) age and sex (2) demographic variables (age, sex, place of residence, and income level). Statistical significance was set at p&lt; 0.05. Results A total of 226,737 individuals (7,958 [3.5%] cases and 218,779 [96.5%] controls) were included in the final analysis. There were more females than males, both in test positives and negatives at 59.9% and 52.3%, respectively. The largest test positive population was those in age group 20 to 29 years (25.5%),. The test negatives had the largest population in age group 30 to 39 years (17.1%). The ratio of newly diagnosed AA was 18/7,958 (0.2%) in cases and 195/218,779 (0.1%) in controls. IRRs of COVID-19 patients having newly diagnosed AA compared to controls were 0.78 (0.48‒1.27) when age and sex were adjusted for, and 0.60 (0.35‒1.03) when all demographic variables were adjusted for. Flowchart of study subject selection Conclusion Diagnosis of COVID-19 was not significantly associated with development of AA even after appropriately adjusting for covariates.

The Exciting Star of the Berkeley 59/Cepheus OB4 Complex and Other Chance Variable Star Discoveries

Field: Physics and Astronomy (Physical Sciences)

A study is presented regarding the nature of several variable stars sampled during a campaign of photometric monitoring from the Abbey Ridge Observatory: 3 eclipsing binaries, 2 semiregulars, a luminous Be star, and a star of uncertain classification. For one of the eclipsing systems, BD+66 1673, spectroscopic observations reveal it to be an O5 V((f))n star and the probable ionizing star of the Berkeley 59/Cep OB4 complex. An analysis of spectroscopic observations and BV photometry for Berkeley 59 members in conjunction with published observations imply a cluster age of ~2 Myr, a distance of d = 883+-43 pc, and a reddening of E(B-V) =1.38+-0.02. Two of the eclipsing systems are Algol-type, but one appears to be a cataclysmic variable associated with an X-ray source. ALS 10588, a B3 IVn star associated with the Cepheid SV Vul, is of uncertain classification, although consideration is given to it being a slowly pulsating B star. The environmental context of the variables is examined using spectroscopic parallax, 2MASS photometry, and proper motion data, the latter to evaluate the membership of the variable B2 Iabe star HDE 229059 in Berkeley 87, an open cluster that could offer a unique opportunity to constrain empirically the evolutionary lineage of young massive stars. Also presented are our null results for observations of a sample of northern stars listed as Cepheid candidates in the Catalogue of Newly Suspected Variables.
Project‐Based Learning Involving Sensory Panelists Improves Student Learning Outcomes

Field: Health Professions (Health Sciences)

Abstract Project‐based, collaborative learning is an effective teaching method when compared to traditional cognitive learning. The purpose of this study was to assess student learning after the completion of a final meal project that involved a group of sensory panelists. A paper survey was conducted among 73 senior nutrition and dietetics students enrolling in Experimental Food Science, Spring 2013 and 2014. The survey comprised of qualitative and quantitative questions about students’ perceived learning outcomes. The project required students to prepare a 4‐course meal in 90 min, in groups of 4. Eighteen sensory panelists consisting of faculty and graduate students from the Nutrition, Dietetics, and Hospitality Management Department and administrative staff from the college evaluated the foods, asked students several food science‐related questions, and completed a survey about their involvement in the project. Students reported that this project reinforced class material (4.7 ± 0.6), and was enjoyable (4.6 ± 0.6) yet challenging (4.4 ± 0.7); numerous skills were developed, including team‐building (4.7 ± 0.5), food preparation (4.6 ± 0.5), and time management (4.4 ± 0.5). Students perceived that the involvement of sensory panelists was beneficial in terms of providing constructive feedback for improvement and motivating them to prepare high‐quality foods. It also prepared them for serving foods to individuals from different cultural backgrounds. However, some students found the experience stressful. For the sensory panelists, the project helped them to venture out of their areas of expertise. In conclusion, a meal project involving sensory panelists can result in positive learning outcomes.
Effects of Multiple Nonnative Fish on an Imperiled Cyprinid, Hornyhead Chub

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract Nonnative fish can have substantial negative effects on the abundance and distribution of native fishes through predation and competition. Nonnative predators are of particular interest because they represent novel threats to native prey species that are not adapted to their presence. Prey species with limited distributions or population sizes may be particularly vulnerable to the effects of nonnative predators. In the Laramie River, four nonnative predators—Brown Trout Salmo trutta , Rainbow Trout Oncorhynchus mykiss , Brook Trout Salvelinus fontinalis, and Smallmouth Bass Micropterus dolomieu are present along with a state‐imperiled population of Hornyhead Chub Nocomis biguttatus . The abundance of Hornyhead Chub has declined with increasing abundance of nonnative predators, with the probability of occurrence of Hornyhead Chub dropping drastically when Smallmouth Bass were present. All four nonnative species preyed on native cyprinids, but Smallmouth Bass relied most heavily on fish as a prey item. Isotopic niche overlap occurred between Hornyhead Chub and all of the nonnative predator species. Our results demonstrate that nonnative predators have the potential to negatively affect the abundance and distribution of Hornyhead Chub through the mechanisms of predation and competition, and predator identity is important in determining the extent of effects. Smallmouth Bass are a greater concern than nonnative salmonids because of their more piscivorous behavior, and their recent upstream expansion may be limiting the downstream distribution of Hornyhead Chub in the Laramie River.
Measuring pure health inequality and mobility during a health insurance expansion: Evidence from Mexico

Field: Health Professions (Health Sciences)

Abstract The association of insurance expansions and the distribution of health status is still a matter we know little about. This paper draws upon new measures of pure (univariate) inequality and mobility which accommodate categorical data to understand how an expansion of public insurance may be related to both health inequality and mobility. These measures require a definition of individual's status that is either “downward looking” or “upward looking”. Using data from the Mexican Family Life Survey, a nationally representative longitudinal survey, we find that the distribution of health has worsened in Mexico between 2002 and 2009, although the change is only consistent for an upward looking definition status. Together with the lack of mobility in self‐reported health, we can thus conclude that Mexico has become more rigid over time despite the rapid public health expansion that took place over the 2000s decade. While further research on the potential drivers of health inequalities is needed, our findings suggest that insurance coverage alone may be not enough to reduce health disparities and promote health mobility. Indeed, health inequality and mobility likely depend on a myriad of factors beyond health care.
An evaluation of exact and approximate 3-D reconstruction algorithms for a high-resolution, small-animal PET scanner

Field: Computer Science (Physical Sciences)

MicroPET is a low-cost, high-resolution positron emission tomography (PET) scanner designed for imaging small animals. MicroPET operates exclusively without septa, acquiring fully three-dimensional (3-D) data sets. The performance of the projection-reprojection (3DRP), variable axial rebinning (VARB), single slice rebinning (SSRB), and Fourier rebinning (FORE) methods for reconstruction of microPET data were evaluated. The algorithms were compared with respect to resolution, noise variance, and reconstruction time. Results suggested that the 3DRP algorithm gives the best combination of resolution and noise performance in 9 min of reconstruction time on a Sun UltraSparc I workstation. The FORE algorithm provided the most acceptable accelerated method of reconstruction, giving similar resolution performance with a 10%-20% degradation in noise variance in under 2 min. Significant degradation in the axial resolution was measured with the VARB and SSRB methods, offsetting the decrease in reconstruction time achieved with those methods. In-plane angular mashing of the 3-D data before reconstruction led to a 50% reduction in reconstruction time but also introduced unacceptable tangential blurring artifacts. This thorough evaluation of analytical 3-D reconstruction techniques allowed for optimal selection of a reconstruction method for the diverse range of microPET applications.

The Needs of Medical Professionals in Performing their Duties during the COVID-19 Pandemic: A Qualitative Research Study

Field: Health Professions (Health Sciences)

Introduction: The COVID-19 pandemic situation is a huge global medical and public health issue that has affected people’s physical health and mental well-being. Under the current circumstances, medical professionals are at risk of stress, anxiety, and subsequent mental health problems. Methods: The present study aimed to explore the needs of medical professionals in terms of promoting their mental health while performing their duties during the COVID-19 pandemic. The purposive sampling method was used to select 43 medical professionals in the following five groups: physicians, dentists, pharmacists, nurses, and medical technicians, who were frontline health workers or had the risk of contracting infection from infected patients in Thai hospitals during the COVID-19 pandemic. The data were collected using a semi-structured online interview. The informants were asked to talk about the need for mental health promotion of medical professionals while performing their duties during the COVID-19 pandemic for approximately 60 minutes. Content analysis and a reliability test were conducted according to the qualitative research process. Results: The research results consisted of three main themes: 1) physical safety welfare, composed of COVID-19 prevention and COVID-19 treatment; 2) sources of mental support, comprising emotional support and electronic or media support; and 3) support from central professional agencies, including rewards and recognition and occupational protection. Conclusion: The medical professionals in this study suggested that the mental health promotion during the COVID-19 pandemic should cover the physical, mental, and social dimensions. Thus, a mental healthcare approach for medical professionals should be developed by focusing on social support.
Fulminant Herpes Simplex Hepatitis Secondary to Adalimumab in Crohn’s Disease: A Case Report

Field: Medicine (Health Sciences)

Herpes simplex virus (HSV) hepatitis is an uncommon cause of fulminant hepatic failure, seen mostly in immunocompromised patients. Conventional treatment modalities for inflammatory bowel disease (IBD), such as steroids and azathioprine, have been known to cause HSV hepatitis. However, the reported incidence of HSV hepatitis in IBD patients undergoing tumor necrosis factor (TNF)-α inhibitor therapy is very rare. In this case report, we describe a rare case of fulminant HSV hepatitis that developed in a patient with Crohn’s disease after treatment with the TNF-α inhibitor, adalimumab.

AUTOMATED COARSE REGISTRATION OF POINT CLOUDS IN 3D URBAN SCENESUSING VOXEL BASED PLANE CONSTRAINT

Field: Computer Science (Physical Sciences)

Abstract. For obtaining a full coverage of 3D scans in a large-scale urban area, the registration between point clouds acquired via terrestrial laser scanning (TLS) is normally mandatory. However, due to the complex urban environment, the automatic registration of different scans is still a challenging problem. In this work, we propose an automatic marker free method for fast and coarse registration between point clouds using the geometric constrains of planar patches under a voxel structure. Our proposed method consists of four major steps: the voxelization of the point cloud, the approximation of planar patches, the matching of corresponding patches, and the estimation of transformation parameters. In the voxelization step, the point cloud of each scan is organized with a 3D voxel structure, by which the entire point cloud is partitioned into small individual patches. In the following step, we represent points of each voxel with the approximated plane function, and select those patches resembling planar surfaces. Afterwards, for matching the corresponding patches, a RANSAC-based strategy is applied. Among all the planar patches of a scan, we randomly select a planar patches set of three planar surfaces, in order to build a coordinate frame via their normal vectors and their intersection points. The transformation parameters between scans are calculated from these two coordinate frames. The planar patches set with its transformation parameters owning the largest number of coplanar patches are identified as the optimal candidate set for estimating the correct transformation parameters. The experimental results using TLS datasets of different scenes reveal that our proposed method can be both effective and efficient for the coarse registration task. Especially, for the fast orientation between scans, our proposed method can achieve a registration error of less than around 2 degrees using the testing datasets, and much more efficient than the classical baseline methods.

Lipase-Catalyzed Aza-Michael Reaction on Acrylate Derivatives

Field: Chemistry (Physical Sciences)

A methodology has been developed for an efficient and selective lipase-catalyzed aza-Michael reaction of various amines (primary and secondary) with a series of acrylates and alkylacrylates. Reaction parameters were tuned, and under the optimal conditions it was found that Pseudomonas stutzeri lipase and Chromobacterium viscosum lipase showed the highest selectivity for the aza-Michael addition to substituted alkyl acrylates. For the first time also, some CLEAs were examined that showed a comparable or higher selectivity and yield than the free enzymes and other formulations.
Web Map Tile Services for Spatial Data Infrastructures: Management and Optimization

Field: Computer Science (Physical Sciences)

Will-be-set-by-IN-TECH Most popular commercial services, like Google Maps, Yahoo Maps or Microsoft Virtual Earth, have already shown that significant performance improvements can be achieved by adopting this methodology, using their custom tiling schemes.The potential of tiled map services is that map image tiles can be cached at any intermediate location between the client and the server, reducing the latency associated to the image generation process.Tile caches are usually deployed server-side, serving map image tiles concurrently to multiple users.Moreover, many mapping clients, like Google Earth or Nasa World Wind, have embedded caches, which can also reduce network congestion and network delay.This chapter deals with the algorithms that allow the optimization and management of these tile caches: population strategies (seeding), tile pre-fetching and cache replacement policies.
