The role of multiple identities in adherence to medical appointments among gay/bisexual male adolescents living with HIV.

Adolescents living with HIV require engagement with care providers in order to access the critical medical and psychosocial services they need. The current study sought to explore developmental determinants of adherence to medical appointments as one aspect of engagement in care among a geographically diverse sample of 200 gay/bisexual male adolescents (16-24 years) living with HIV, with a specific focus on ethnic identity, sexual orientation identity, and identity as a young man living with HIV. Ethnic identity affirmation (OR = 0.6; 95% CI: 0.3, 0.9), morality of homosexuality (OR = 1.7; 95% CI: 1.2, 2.5), and HIV-positive identity salience (OR = 1.5; 95% CI: 0.9, 2.4) were associated with significantly higher risk for missed appointments in the past 3 months. These findings highlight the importance of attending to developmental factors, such as the development of multiple identities, when attempting to increase engagement in care for gay/bisexual male adolescents living with HIV.

The Spanish experience of future classrooms as a possibility of smart learning environments.

Developing advanced technologies and their integration into educational spaces generates new training opportunities. Examples of these are Future Classrooms (FC) and Smart Learning Environments (SLE), two concepts linked to educational innovation through technology but also have their differences. This paper aims to identify the similarities and differences between FC developed in the Spanish formal educational context concerning the theory of SLE. This study follows an exploratory research methodology using an ad hoc questionnaire applied transversally to a representative sample of teachers involved in the SLE (N = 66). SPSS V. 28 software was used. In relation to the results, some statistics (mean, standard deviation, kurtosis and skewness) were used to analyse the developed FC practices and professional satisfaction. In conclusion, the FC are at an initial stage of development in Spain, and although they could represent an approximation to what would be the practical basis of SLE, there are still several aspects to be developed, especially in relation to the technologies used and the dimension of attention to diversity. In relation to SLE technologies, they are related to the automation of certain processes and include artificial intelligence, learning analytics and sensors, among others. On the other hand, these technologies are not widely used in the FC, and the use of other more conventional technological resources, such as interactive whiteboards, online collaborative environments, LMS platforms, etc. In terms of attention to diversity, despite the existence of initiatives to personalise the learning experience in FC, assistive technologies are not considered, nor is automatic personalisation through certain SLE technologies.

Establishment of the mayfly Cloeon dipterum as a new model system to investigate insect evolution.

The great capability of insects to adapt to new environments promoted their extraordinary diversification, resulting in the group of Metazoa with the largest number of species distributed worldwide. To understand this enormous diversity, it is essential to investigate lineages that would allow the reconstruction of the early events in the evolution of insects. However, research on insect ecology, physiology, development and evolution has mostly focused on few well-established model species. The key phylogenetic position of mayflies within Paleoptera as the sister group of the rest of winged insects and life history traits of mayflies make them an essential order to understand insect evolution. Here, we describe the establishment of a continuous culture system of the mayfly Cloeon dipterum and a series of experimental protocols and omics resources that allow the study of its development and its great regenerative capability. Thus, the establishment of Cloeon as an experimental platform paves the way to understand genomic and morphogenetic events that occurred at the origin of winged insects.

[Prevention of vascular ulcers and diabetic foot. Non-randomized open clinical evaluation on the effectiveness of "Mepentol Leche"]. / Prevención de ulceras vasculares y pie diabético. Evaluación clínica abierta no aleatorizada sobre la efectividad de Mepentol Leche.

INTRODUCTION: Vascular ulcers and diabetic foot ulcers present a health serious problem which affects a large number of patients, creating a major challenge for health professionals. Hyper-oxygenated fatty acid dressings have proven to be effective thanks to their favorable action on the skin in three ways: increasing the microcirculation of the blood, promoting the renovation of the epidermic cells, and notably increasing cutaneous hydration. OBJECTIVE: Evaluate the effectiveness of Mepentol Leche, an emulsion based on Hyper-oxygenated fatty acids, Aloe barbadensis and Mimosa tenuiflora, used to treat the skin and alleviate symptoms in patients who suffer from vascular ulcers and diabetic foot ulcers. METHODS: Clinical evaluation carried out between June 2004 and December 2005. 195 patients were studied. The parameters for inclusion in this study were 32.82% for venous pathology 35.90% for skin care, 26.67% due to arterial pathology, and 4.62% for a lymphatic pathology. These patients were evaluated over a one month period and each had a follow-up by means of a data collection file. The guideline to apply this product was twice a day and always over integral skin. The effectiveness of this product has been established based on these epigraphs: symptoms of itching, smarting and pain, and skin conditions: color, dryness, edema, maceration, rashes, and desquamation. RESULTS: Not one patient developed new lesions in healthy skin protected by Mepentol Leche. Symptoms linked to this pathology saw improvements in these percents: itching 96%, smarting 93%, and pain 96%, and skin conditions: color 100%, edema 90%, maceration 96%, rashes 92%, and desquamation 100%. Health professionals' evaluation of this product has been highly favorable in regards to ease of use, tolerance, absorption, and ease of application. CONCLUSIONS: This study showed the benefits in applying this product systematically to alleviate the symptoms prior to the appearance of ulcers, thus avoiding skin dryness and reducing itching, smarting, pain and eczema while returning normal color to the skin.

TEDS site phosphorylation of the yeast myosins I is required for ligand-induced but not for constitutive endocytosis of the G protein-coupled receptor Ste2p.

The yeast myosins I Myo3p and Myo5p have well established functions in the polarization of the actin cytoskeleton and in the endocytic uptake of the G protein-coupled receptor Ste2p. A number of results suggest that phosphorylation of the conserved TEDS serine of the myosin I motor head by the Cdc42p activated p21-activated kinases Ste20p and Cla4p is required for the organization of the actin cytoskeleton. However, the role of this signaling cascade in the endocytic uptake has not been investigated. Interestingly, we find that Myo5p TEDS site phosphorylation is not required for slow, constitutive endocytosis of Ste2p, but it is essential for rapid, ligand-induced internalization of the receptor. Our results strongly suggest that a kinase activates the myosins I to sustain fast endocytic uptake. Surprisingly, however, despite the fact that only p21-activated kinases are known to phosphorylate the conserved TEDS site, we find that these kinases are not essential for ligand-induced internalization of Ste2p. Our observations indicate that a different signaling cascade, involving the yeast homologues of the mammalian PDK1 (3-phosphoinositide-dependent-protein kinase-1), Phk1p and Pkh2p, and serum and glucocorticoid-induced kinase, Ypk1p and Ypk2p, activate Myo3p and Myo5p for their endocytic function.

HIV prevention programs of nongovernmental organizations in Latin America and the Caribbean: the Global AIDS Intervention Network project / Programas de prevención de VIH de organizaciones no gubernamentales en América Latina y el Caribe. El proyecto Global AIDS Intervention Network

Objetivo. Describir los programas de prevención de la infección por VIH y el sida de algunas organizaciones no gubernamentales (ONG). Métodos. Estudiamos, en cada una de los 23 países que participan en el proyecto Global AIDS Intervention Network (GAIN) en América Latina y el Caribe, una ONG que lleva a cabo programas de prevención. La muestra se seleccionó mediante un proceso bietápico: 1) una búsqueda en bases de datos y otras fuentes; 2) la identificación de las ONG mejor establecidas y más activas en el campo de la prevención de la infección por VIH, según fuentes autorizadas. A los directores ejecutivos se les hizo preguntas acerca de los programas de prevención, el personal, los presupuestos, las poblaciones con las que trabajaban y las barreras a su trabajo. Resultados. Las 23 ONG llevaban a cabo 58 programas de servicio directo y tenían un promedio de 8 años de estar proveyendo programas de prevención. El promedio anual del presupuesto era de US$ 205 393 (intervalo de US$ 10 000 a US$ 1 440 000), y el número promedio de empleados a tiempo completo era de 4,5 (intervalo de 0­15, DE = 4,7.) Muchas ONG dependían de los voluntarios para los programas de prevención (mediana = 10, promedio = 51, intervalo de 0­700, DE = 150). Las ONG ofrecían programas de prevención dedicados a la comunidad en general (82,6%), a jóvenes y adolescentes (34,8%), y a hombres que tienen relaciones sexuales con otros hombres (30,4%). Las actividades de las ONG consistían en entrenar a los entrenadores para todo tipo de actividades (43,5%) y en realizar programas de prevención cara a cara con los participantes (34,8%). Se citaron como obstáculos la falta de fondos (60,9%) y la discriminación y estigma relacionados con la infección por el VIH (56,5%). Conclusiones. Las estrategias que emplean estas ONG para sobrepasar las barreras a la prevención son prueba de su inventiva y dedicación y sirven como ejemplo para las ONG en otras regiones del mundo

Objective. The objective of this paper is to describe HIV prevention programs conducted by nongovernmental organizations (NGO) that are meeting this challenge. Methods. One NGO undertaking HIV prevention programs was evaluated in each of the 23 countries participating in the Global AIDS Intervention Network (GAIN) Project throughout Latin America and the Caribbean. A two-stage selection process was used: (1) a search in databases and other information sources; (2) identification of NGOs that were best established and most actively engaged in HIV prevention activity. Executive directors were questioned these entities. Results. The 23 NGOs conducted 58 direct-service programs and had been conducting HIV prevention activities for a mean of 8 years (SD = 4.45; range 1­18 years). Average annual program budget was US$ 205 393 (range: US$ 10 000 to US$ 1 440 000). The NGOs reported a mean of 4.5 full-time employees (range 0­15, SD = 4.7). Many relied on volunteers (median = 10, mean = 51, range 0­700, SD = 150) to conduct HIV prevention activities. The NGOs provided prevention services for the general community (82.6%), children and adolescents (34.8%) and men who have sex with men (30.4%). Activities conducted by NGOs included train-the-trainer activities (43.5%) and face-to-face prevention activities (34.8%). Obstacles cited included lack of funding (60.9%) and HIV-related stigma and discrimination (56.5%). Conclusion. The strategies used by NGOs to overcome barriers to prevention are a testament to their ingenuity and commitment, and serve as examples for NGOs in other world regions
