El presente artÃ­culo tiene como objetivo realizar un anÃ¡lisis sobre el cambio de hÃ¡bitos del consumidor en tiempos de pandemia de la Cd. de Pachuca, Hidalgo, y su zona metropolitana, principalmente relacionado con las elecciones de compra que realizan sobre los productos de la canasta bÃ¡sica, basÃ¡ndose en frecuencia y lugar. Para lograrlo se tomÃ³ como base la teorÃ­a de la motivaciÃ³n humana de Maslow, y posteriormente se realizÃ³ una encuesta aleatoria a los consumidores que tienen poder de compra en sus familias, alcanzando un total de 345 personas encuestadas. En este estudio se pudo encontrar que los hÃ¡bitos de compra han tenido poca variaciÃ³n en cuanto al lugar de compra, incrementÃ¡ndose el consumo en tiendas de abarrotes y de conveniencia; la frecuencia de compra ha disminuido, asÃ­ como el presupuesto asignado ha tenido variaciones; en las revisiones realizadas se pudo observar que los pagos electrÃ³nicos han sufrido un incremento. Los resultados obtenidos y las conclusiones a las que se llegan permiten visualizar la importancia que tiene para las empresas de cualquier tamaÃ±o el desarrollo de estrategias que permitan reinventarse y acceder a los mercados de manera exitosa, adaptÃ¡ndose a la â€œnueva normalidadâ€ de los consumidores.

This paper focuses on carrying out an analysis on the change in consumer habits during the pandemic period in the City of Pachuca, Hidalgo, and its metropolitan area. This is mainly related to the choices they make about the products of the basic basket, based on frequency and location. To achieve this, Maslow's theory of human motivation was taken as a basis. A random survey was also conducted among consumers who have purchasing power in their families, thus a total of 345 people were surveyed. In this study, it was found that shopping habits have had little variation in the aspect of the place of purchase. This has led to increase in grocery and convenience stores, the frequency of purchase has decreased, and the assigned budget has had variations. In the reviews carried out, it was observed that electronic payments have also suffered an increase. The results obtained and the conclusions reached made it possible to visualize the importance for companies of any size to develop strategies that allow them to reinvent themselves and successfully access markets, in order to adapt to the â€œnew normalâ€ of consumers.

El uso de las aplicaciones mÃ³viles para pedir comida se ha tornado en algo natural para el consumidor que vive en la contingencia causada por COVID-19, sin embargo, no se ha convertido en un hÃ¡bito ni ha generado dependencia o adicciÃ³n alguna para tal fin. El enfoque de la presente investigaciÃ³n es cuantitativo de alcance descriptivo, transversal simple. Como tÃ©cnica de recolecciÃ³n se empleÃ³ la encuesta electrÃ³nica por internet, aplicÃ¡ndose a 75 personas habitantes de la ciudad de Puebla que utilicen aplicaciones mÃ³viles de entrega de alimentos, la cual se conforma por 32 Ã­tems. Se analizÃ³ el perfil del consumidor de comida a travÃ©s de aplicaciones mÃ³viles, sus hÃ¡bitos y actitudes hacia el servicio, con la finalidad de generar estrategias de comercializaciÃ³n a travÃ©s de la segmentaciÃ³n. Se detectÃ³ que factores como el ahorro de tiempo, dinero y rapidez en la entrega de alimentos son valorados por la mayorÃ­a; no obstante, existe claramente un segmento de mercado que posee caracterÃ­sticas que lo distinguen en cuanto al perfil y gasto se refiere. El uso promedio es de una sola aplicaciÃ³n, siendo Uber Eats la que mÃ¡s demanda tiene, el momento de mayor frecuencia para la compra de alimentos es por la noche, con un gasto menor a los $500 al mes y la razÃ³n principal, es para no salir de casa.

The use of mobile applications to order food has become something natural for the consumer who lives in the contingency caused by COVID-19. It, however, has not developed into a habit, neither has it generated any dependency nor addiction for this purpose. This paper uses a quantitative approach, descriptive in scope, and follows a simple transversal. As a collection technique, the electronic survey was used on the internet and it was applied to 75 inhabitants of the city of Puebla that use mobile applications for food delivery, which is made up of 27 items. The profile of the food consumer, their habits and attitudes towards the service, was analyzed through mobile applications in order to generate marketing strategies through segmentation. The results show that factors such as saving time, money, and the speed of food delivery are valued by most people. There is also a clear market segment that has features that distinguish it in terms of profile and spending. The average use is just a single app, i.e., Uber Eatsâ€“â€“the one with the most demand. People buy food more frequently at night, with an expense of less than $500 a month due to home delivery.

Introduction: Hormonal changes affecting a child's growth occur in deep sleep phase of preschoolers. Nowadays, obesity is still a world health problem. In 2014, Indonesia had three growth problems, one of them was overweight in preschoolers. This study aimed to analyze the association between sleep disturbance with weight-for-height and body mass index (BMI) in preschoolers. Methods: This was a cross-sectional study by analyzing the tendency with boxplot charts and the association was measured by Mann-Whitney test and independent t-test. Data of 86 preschoolers aged 3-5 years old were obtained from three kindergartens in Kalijudan, Surabaya from March to September 2018. Z-score values and the categories of weight-for-height Z-score (WHZ) and BMI-for-age Z-score (BAZ) refer to WHO Standards 2006 and sleep disturbances were measured by sleep disturbance scale for children (SDSC) questionnaire. Results: 65.12% of preschoolers had sleep disturbance and 66.28% of them had normal WHZ and BAZ. The average WHZ and BAZ value in preschoolers who had sleep disturbance (M = -0.2730; -0.2207) were higher than preschoolers who had no sleep disturbance (M = -0.6083; -0, 5920). Results from Mann-Whitney test showed the same significance value between WHZ and BAZ, p = 0.226. Independent t-test showed a significance value of p = 0.524 and p = 0.490, meaning that there was no statistically significant association. Conclusion: There was no statistically significant association between sleep disturbance with WHZ and BAZ in preschoolers aged 3-5 years old, however descriptively, the values of WHZ and BAZ in the group of preschoolers who had sleep disturbance tended to be higher.

Wave-Slope Soaring of the Brown Pelican
Authors: Stokes Ian , Lucas Andrew 
Published: February 2021

Abstract
Background: From the laboratory at Scripps Institution of Oceanography, it is common to see the brown pelican (Pelecanus occidentalis) traveling along the crests of ocean waves just offshore of the surf zone. When flying in this manner, the birds can travel long distances without flapping, centimeters above the ocean's surface. Here we derive a theoretical framework for assessing the energetic savings related to this behavior, `wave-slope soaring,' in which an organism in flight takes advantage of localized updrafts caused by traveling ocean surface gravity waves. Methods: The energy cost of steady, constant altitude flight in and out of ground effect are analyzed as controls. Potential flow theory is used to quantify the ocean wave-induced wind associated with near-shoaling, weakly nonlinear, shallow water ocean surface gravity waves moving through an atmosphere initially at rest. Using perturbation theory and the Green's function for Laplace's equation in 2D with Dirichlet boundary conditions, we obtain integrals for the horizontal and vertical components of the wave-induced wind in a frame of reference moving with the wave. Wave-slope soaring flight is then analyzed using an energetics-based approach for waves under a range of ocean conditions and the body plan of P. occidentalis . Results: For ground effect flight, we calculate a ~ 15 - 25% reduction in cost of transport as compared with steady, level flight out of ground effect. When wave-slope soaring is employed at flight heights ≤ 2m in typical ocean conditions (2m wave height, 15s period), we calculate 60-70% reduction in cost of transport as compared with flight in ground effect. A relatively small increase in swell amplitude or decrease in flight height allows up to 100% of the cost of transport to be offset by wave-slope soaring behavior. Conclusions: The theoretical development presented here suggests there are energy savings associated with wave-slope soaring. Individual brown pelicans may significantly decrease their cost of transport utilizing this mode of flight under typical ocean conditions. Thus wave-slope soaring may provide fitness benefit to these highly mobile organisms that depend on patchy prey distribution over large home ranges.

Abstract
Background The Reporting Items for Practice Guidelines in Healthcare (RIGHT) checklist was used to assess the reporting quality of 2009–2019 Clinical Practice Guidelines (CPGs) regarding gout and hyperuricemia, aimed to improve the reporting quality of future guidelines.Methods We searched PubMed, the Chinese Biomedical Literature database, the Wan Fang Database, and the China National Knowledge Infrastructure from January 2009 to June 2019 for guidelines regarding gout and hyperuricemia. We also searched the websites of guideline development organizations (the Guidelines International Network, the National Institute for Health and Clinical Excellence, the American College of Rheumatology, and the European League Against Rheumatism) (EULAR). Furthermore, supplementary guidelines reported in included articles were systematically searched, as well as Medlive and Google Scholar.Results Seventeen guidelines were included, of which one was in Chinese and 16 were in English. The mean reporting rate of the 35 items specified was 14.9 (42.5%), only five CPGs (29.4%) had a reporting rate >50%. Of the 35 items, three were very frequently reported. The reporting proportion of the seven domains (Basic information, Background, Evidence, Recommendations, Review and quality assurance, Funding and declaration and management of interests, and Other information) were 64.7%, 36.8%, 50.6% 50.6%, 42.9%, 8.82%, 33.8%, and 31.4%, respectively.Conclusion The reporting quality of the present guidelines for gout and hyperuricemia is relatively poor. We suggest that the RIGHT reporting checklist should be used by CPG developers to ensure higher reporting quality of future guidelines.

Abstract
This study evaluates the total economic loss due to the outbreaks of African Swine Fever (ASF) in China between August 2018 and July 2019. We propose a systematic framework to assess both the direct economic loss on the Chinses breeding industry and indirect economic loss on other sectors. Our evaluation system integrates various statistical analysis methods by applying the cost-loss model and substitution indicator method to calculate direct economic losses and using input-output (IO) model to estimate indirect economic losses. The proposed method provides an innovative and commonly applicable way to deal with the missing data that needs to be adjusted and repaired to be used for economic shock evaluation. We find that total economic loss caused by ASF is 224.768 billion yuan consisting of 99.042 billion yuan direct economic loss of the breeding industry and 125.726 billion yuan indirect economic loss of other industries. Our findings suggest that the overall impact of ASF on China's national economy is relatively small, mainly local and short-term impacts on the swine industry.

Abstract
Background

Burns are one of the most common injuries in daily life for all ages of population. This study was to investigate the epidemiology and outcomes among burn patients in one of the largest burn centers in the southwest of China.
Methods

The study was performed at the Institute of Burn Research in the first affiliated with the Army Medical University (AMU). A total of 17939 burn patients were included in this retrospective study. Information regarding demographic, burn characteristics, and the burn severity of ABSI were collected, calculated and compared.
Results

The age ranged from 257 days to 95 years old. Scalding and flame were the two most common causes to burn injuries, comprising of 91.96% in total. Limbs, head/face/neck, and trunk were the most frequently occurred burn sites, with the number and the percent of 12324 (68.70%), 7989 (44.53%), and 7771 (43.32%), respectively. The average total body surface area (TBSA) was 13.64 ± 16.83% (median 8%) with a range of 0.1 ~ 100%. A total of 874 (4.9%) patients had TBSA > 50%. The presence of a burn with an inhalation injury was confirmed in 543 patients (3.03%). The average LOS was 32.11 ± 65.72 days (median: 17days). The gender of male, the older age and the full-thickness burns were significant contributors to high medical cost. The gender of male, the older age and the full-thickness burns were significantly associated with high medical cost and were contributors to the mortality. Eventually, the retrospective analysis resulted in the development of a framework of burn management continuum used for developing strategies to prevent and manage severe burns.
Conclusion

The annual number of burn injuries has kept decreasing while the cure rates of severe burns have improved; However, the burn severity and the economic burden were still in a high level. The gender difference and age difference should be considered when making individualized interventions and rehabilitative treatments.

Published: February 2021

Abstract
Background: The efficacy of interventions for elderly patients with sarcopenia has received increasing attention. Exercise and nutrition have been recognized as effective treatments for sarcopenia in many studies. However, evidence-based support from relevant studies is still lacking. Methods: The PubMed, Embase, Cochrane Library, VIP, CNKI, and SinoMed databases were searched. The basis for the diagnosis of sarcopenia, general condition of the subjects, duration and methods of exercise/nutritional therapy, outcome indicators, and quality of evidence were evaluated, and a meta-analysis of differences in treatment outcomes between the groups from baseline to the end of each study was conducted. Results: A total of 1860 papers were screened, including six randomized controlled trials, and the effects of protein intervention under exercise conditions on muscle mass, strength, and function in elderly patients with sarcopenia were investigated. The results showed that protein supplementation under resistance exercise conditions had the following effects on elderly patients with sarcopenia: there was a significant difference in knee flexion and extension strength (p = 0.02), grip strength (p = 0.02), fat mass (p = 0.04), and normal pace and pace (p = 0.0008 and p = 0.0010, respectively) between the intervention group and baseline data.Conclusion: The meta-analysis revealed some positive effects of protein intervention treatment under exercise conditions on elderly patients with sarcopenia. However, the quality of evidence is low. High-quality randomized controlled trials should be conducted in the future to provide a better clinical basis. Keywords: Sarcopenia, Exercise, Proteins
