New Applications of 3D SLAM on Risk Management Using Unmanned Aerial Vehicles in the Construction Industry

Risk Management is an integral part of the Corporate Governance of the Companies, whose objective is to estimate the risks related to each line of business and to make appropriate decisions regarding the adoption of preventive measures. The construction industry, due to its peculiar characteristics about occupational risks, is a sector that must pay particular attention to this issue. Unmanned aerial robots are part of a generation of new technologies, which are emerging in the attempt to develop robust and efficient algorithms capable of obtaining 3D models of structures under construction, to support the assessment of the situation in case of an eventuality, before the direct human intervention. This article proposes to develop a risk management strategy for the construction industry based on obtaining 3D models of work environments using drones, which will allow safe evaluation of risks present in construction zones

Revisión taxonómica de Salvia subgénero Calosphace sección Scorodoniae (Lamiaceae), endémica de México

Background and Aims: The Mexican section Scorodoniae, of Salvia subgenus Calosphace is reviewed. Contributing to the efforts to know the Mexican flora several sections sensu Epling are being reviewed by different authors, including diagnostic characters and species descriptions. Even with Turner’s short treatment of Salvia sect. Scorodoniae several species remained difficult to identify. The objective of this research was to diagnose Scorodoniae, provide species descriptions, synonyms, type specimens, an identification key and distribution maps. Methods: Four hundred and sixty specimens of Salvia secc. Scorodoniae deposited at EBUM, ENCB, IEB, MEXU y UAMIZ were reviewed. Identification was made using several taxonomic treatments, protocols and type specimens. Key results: Salvia tepicensis is a synonym of S. aequidistans. Salvia dugesii and S. gonzalezii are recognized as species and no longer treated as synonyms of S. melissodora y S. pannosa respectively. Salvia fruticulosa previously classified in sect. Tomentellae is now placed in Scorodoniae. Conclusions: Sixteen species of Salvia section Scorodoniae are recognized, characterized by the deltoid, ovate to ovate-lanceolate or elliptic-lanceolate lamina, with bullate-rugose upper surface, and their small flowers.Antecedentes y Objetivos: Se reevalúa la sección mexicana Scorodoniae de Salvia subgénero Calosphace.

Guidelines for the Standardization of Genital Photography

Plastic surgery relies on photography for both clinical practice and research. The Photographic Standards in Plastic Surgery laid the foundation for standardized photography in plastic surgery. Despite these advancements, the current literature lacks guidelines for genital photography, thus resulting in a discordance of documentation. The authors propose photographic standards for the male and female genitalia to establish homogeneity in which information can be accurately exchanged. All medical photographs include a sky-blue background, proper lighting, removal of distractors, consistent camera framing, and standard camera angles. We propose the following guidelines to standardize genital photography. In the anterior upright position, feet are shoulder-width apart, and arms are placed posteriorly. The frame is bounded superiorly by the xiphoid-umbilicus midpoint and inferiorly by the patella. For circumferential documentation, frontal 180 degree capture via 45 degree intervals is often sufficient. Images in standard lithotomy position should be captured at both parallel and 45 degrees above the horizontal. Images of the phallus should include both the flaccid and erect states. Despite the increasing incidence of genital procedures, there lacks a standardized methodology in which to document the genitalia, resulting in a substantial heterogeneity in the current literature. Our standardized techniques for genital photography set forth to establish a uniform language that promotes more effective communication with both the patient as well as with colleagues. The proposed photography guidelines provide optimal visualization and standard documentation of the genitalia, allowing for accurate education, meaningful collaborations, and advancement in genital surgery

APLICACIÓN DEL MODELO EN ESPIRAL PARA DESARROLLO DE PROTOTIPO DE PÁGINA WEB DURANTE LA PANDEMIA DE COVID-19 (APPLICATION OF THE SPIRAL MODEL FOR THE DEVELOPMENT OF A WEBSITE PROTOTYPE DURING THE COVID-19 PANDEMIC)

Resumen La pandemia por Coronavirus que se está viviendo en el mundo, ocasionó que muchas actividades no esenciales se suspendieran o de ser posible, se continuase trabajando desde los hogares. Es por lo anterior que el objetivo del presente proyecto, fue el de aplicar el modelo de ciclo de vida de software en espiral para el desarrollo del prototipo de software en dieciséis semanas. La funcionalidad principal del prototipo, fue calcular los niveles de competitividad en unidades de producción agrícola; por lo que hizo uso de la escala Uaqui, que determina los niveles de competitividad en unidades de producción guanajuatenses. El proyecto planteó laborar seis horas de lunes a viernes, de acuerdo a las etapas del ciclo de vida en espiral; así como los posibles riesgos que pudieran ocasionar que se alargase el proyecto debido al trabajo a distancia y obtuvo como resultado el desarrollo del proyecto dentro del tiempo planeado, entregando un prototipo que comprobó que determinaba los niveles de competitividad correspondientes.

Aeroallergen immunotherapy associated with reduced risk of severe COVID-19 in 1095 allergic patients

Introduction: Allergen immunotherapy (AIT) brings along changes in the immune system, restoring dendritic cell function, reducing T2 inflammation and augmenting the regulatory cell activation. Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, interferes with the immune system causing immune suppression during the first phase and over-activation in more advanced disease. We decided to explore the interaction of both in a real-world observational trial. Methods: We registered COVID-19 outcomes in patients with allergic disorders in Latin America, treated with and without AIT. The registry was conducted during the first 1.3 years of the pandemic, with most of the data collected before COVID-19 vaccination was concluded in most countries. Data collection was anonymous via a web-based instrument. Ten countries participated. Results: 630/1095 (57.6%) of the included patients received AIT. Compared to patients without AIT, those treated with AIT had a reduced risk ratio (RR) for COVID-19 lower respiratory symptoms (RR 0.78, 95% CI: 0.6703–0.9024; p = 0.001662) and need for oxygen therapy (RR 0.65, 95% CI: 0.4217–0.9992; p = 0.048). In adherent patients on maintenance sublingual immunotherapy/subcutaneous immunotherapy (SLIT/SCIT) the RR reduction was larger [RR = 0.6136 (95% CI 0.4623–0.8143; p < 0.001) and RR: 0.3495 (95% CI 0.1822–0.6701; p < 0.005), respectively]. SLIT was slightly more effective (NS). We excluded age, comorbidities, level of health care attendance, and type of allergic disorder as confounders, although asthma was related to a higher frequency of severe disease. When analyzing patients with allergic asthma (n = 503) the RR reduction favoring AIT was more pronounced with 30% for lower respiratory symptoms or worse (RR 0.6914, 95% CI 0.5264 to 0.9081, p = 0.0087) and 51% for need of oxygen therapy or worse (RR 0.4868, 95% CI 0.2829–0.8376, p = 0.0082). Among severe allergic patients treated with biologics (n = 24) only 2/24 needed oxygen therapy. There were no critical cases among them. Conclusion: In our registry AIT was associated with reduced COVID-19 severity
