Transgender and gender diverse youth (TGDY) can be a challenging population to reach because of limitations related to parental/guardian consent and concerns about privacy. This pilot study's purpose was to assess the feasibility of recruiting a US nation-wide longitudinal sample of TGDY through social media, and to compare participants who completed the Wave 1 survey only to TGDY who completed both Wave 1 and Wave 2 surveys. Adolescents (aged 14–17 years) who identified as TGDY were recruited through social media and invited to complete two online surveys across a 3-month period. Surveys included measures of mental health, substance use, and community connection. The Wave 1 sample included 252 TGDY, with 183 (73%) retained at Wave 2. There were few differences (i.e., gender identity; sex assigned at birth) between Wave 1–only participants and those retained at Wave 2. Findings demonstrate the feasibility of recruiting a U.S. nation-wide longitudinal sample of TGDY through social media, providing an important platform for conducting research to improve well-being of TGDY.

The commitment to a more sustainable world in social and environmental terms requires product design and development (PDD) models that will help achieve this goal. Based on a dialogue between theory and practice, this paper presents the reflections that led to such a sociotechnical model, including its main principles: Ergonomics Quality in Design (EQUID) 4.0. It is grounded on a broad concept of ergonomics and human factors (E/HF), going beyond the traditional, narrow view of E/HF in PDD. EQUID 2.0 included the organisational dimension in the design process but left its role only in the immediate sphere of product design. EQUID 4.0 recognises that E/HF quality in the design process depends on a higher level, i.e. the organisation itself and integrates the contributions of preceding versions in an expanded E/HF concept: one that proposes that E/HF should always include not just the social but also the environmental dimension of sustainability. THEORETICAL RELEVANCE: If a tool or method that aims to contribute to inserting E/HF into production spheres is to be proposed, there is a need to establish a conceptual framework derived from a dialogue between E/HF theory and practice in relation to quality, sustainability, and product design and development.

In this work, partial reductive amination of 5‐hydroxymethylfurfural (HMF) with gaseous ammonia over iridium supported on γ‐Al2O3, TiO2, SiO2 and carbon has been studied. The influence of the support and pressure was investigated in the valorization under mild conditions of HMF to 5‐(aminomethyl)‐2‐furanmethanol (AMFM). The catalysts were characterized by TEM, SEM‐EDS, N2 sorption Isotherms, TGA, CO‐Chemisorption, TPR, XRD, NH3‐TPD, ICP‐AES and XPS. The maximum activity and high rates were obtained for all catalytic systems. At 50 minutes of the reaction the Ir/C catalyst achieved 93 % of conversion and exhibited the highest yield and selectivity of 92 % and 99 % respectively, to the desired product 5‐(aminomethyl)‐2‐furanmethanol. The main properties that influence activity and selectivity are related to the amount of iridium on the surface and catalyst acidity. After the third cycle, 63 % and 59 % of selectivity and yield to AMFM respectively at 93 % of conversion were obtained. [ABSTRACT FROM AUTHOR]

The current waste management system within the Extravehicular Mobility Unit (EMU) consists of a disposable diaper—the Maximum Absorbency Garment (MAG)—that collects urine and feces during extravehicular activities (EVAs) that last up to 8 h. Such exposure to waste for prolonged periods of time contributes to hygiene-related medical events, including urinary tract infections and gastrointestinal distress. Historically, prior to using the MAG, astronauts have limited their food intake or eaten a low-residue diet before embarking on physically demanding spacewalks, reducing their work performance index (WPI) and posing a health risk. Furthermore, the current 0.95 L In-suit Drink Bag (IDB) does not provide sufficient water for more frequent, longer-range spacewalks, which carry greater potential for contingency scenarios requiring extended time away from a vehicle. High transport costs per pound to space and resource scarcity exacerbate these challenges, underscoring the need for water efficient waste management. This paper introduces a novel in-suit urine collection and filtration system developed in the Mason Lab at Weill Cornell Medical College that could address these hygiene and hydration concerns. The device would collect astronaut urine via an external catheter and filter it using forward and reverse osmosis (FO-RO) into potable water, creating a sustainable and hygienic circular water economy, enhancing astronaut wellbeing. This research aims to achieve an 85% urine collection rate using a modified MAG. The modified MAG will be made of a flexible compression material lined with antimicrobial fabric, and urine is collected through a silicone urine collection cup, which differs for male and female astronauts to conform to anatomy. Urine collection via a vacuum pump is triggered by a humidity sensor that detects the presence of urine in the cup. The FO-RO filtration system targets a minimum of 75% water recovery, while consuming less than 10% of EMU energy. To meet health standards, the filtrate maintains low salt levels (<250 ppm NaCl) and effectively removes major urine solutes (urea, uric acid, ammonia, calcium). However, further research and testing are warranted to refine and implement these innovations for future space missions, contributing to the advancement of deep space exploration technologies and astronaut health and performance.

Tuberculosis is a chronic infectious-contagious disease that primarily affects the lungs but can affect any part of the body. BCG or Bacille Calmette-Guerin is a vaccine against tuberculosis disease. It is a preparation of live attenuated bacteria derived from a culture of Bacille Calmette-Guerin (Mycobacterium bovis). The BCG vaccine, in addition to its specific protective effect against tuberculosis, stimulates trained innate immunity, resulting in protective effects against other infectious and non-infectious diseases other than tuberculosis. Specific protection against the disease is carried out with BCG vaccination in the newborn. This is a basic review of benefit concepts of this vaccine to avoid tuberculosis and its application in other diseases. [ABSTRACT FROM AUTHOR]

This study focussed on the work system design to be used by a colombian food sector company for distributing products. It considered the concept of participative ergonomics, where people from the commercial, logistics, operation, occupational health areas worked in conjunction with the industrial designers, ergonomists who methodologically led the project. As a whole, the project was conceived as having five phases: outline, diagnosis, modelling the process, scalability, instrumentation. The results of the project translate into procedures for selecting, projecting a new distribution centre, the operational process model, a description of ergonomic systems that will enable specific work stations to be designed, the procedure for adapting existing warehouses. Strategically, this work helped optimise the company's processes and ensure that knowledge would be transferred within it. In turn, it became a primary prevention strategy in the field of health, aimed at reducing occupational risks, improving the quality of life at work.
