Where does Aedes albopictus (Diptera: Culicidae) really breed in a Mediterranean residential area? Results from a field study in Valencia, Eastern Spain.

Since its introduction in Spain in 2004, Aedes albopictus has rapidly spread across the country. Its aggressive biting behaviour causes nuisance, limiting outdoor activities. Also, its role as a vector of several arboviruses implies a major public health risk, with several cases of autochthonous dengue having been reported nationwide over the past few years. Control strategies usually focus on interventions in breeding sites. As such, accurate knowledge of the main larval habitats becomes a major priority in infested areas. A detailed identification of breeding sites of Ae. albopictus was carried out in the outdoors of 60 residential properties during July-August 2022 in El Vedat de Torrent (Valencia, Eastern Spain), an area recently colonised by this species. A total of 1444 real and potential breeding sites were examined. The most abundant potential larval habitat were plant pot plates (6.48 units/house), although a low infestation level was found, both for larvae (2.06% positivity, x̄ = 30.5 larvae/container), and pupae (0.51%, x̄ = 2.5 pupae/container). A total of 7715 larvae and 205 pupae were found in a disused flooded water pool depuration system. Animal drinkers, buckets and irrigation water containers were found to be the most common positive containers. No statistical difference was observed among the different container materials. A general statistical increase of 1 larva per 11.7 ml of water in breeding sites was detected. Breeding sites of other species such as Culex pipiens (n = 2) and Culex modestus (n = 1) were also rarely found in this residential area. To our knowledge, this is the first aedic index study carried out in Europe, and it provides valuable information about the main domestic breeding habitats of Ae. albopictus, which can greatly improve control programmes.

Avances en el trabajo de equipos multidisciplinares para la atención al paciente con asma grave no controlada. Una visión post-COVID (Proyecto TEAM 2.0) / Advances in the work of multidisciplinary teams for the care of patients with severe uncontrolled asthma. A post-COVID vision (TEAM 2.0 project)

El asma es una enfermedad respiratoria crónica con un alto impacto sanitario, social y económico, en particular, en el caso del asma grave no controlada (AGNC). Por ello, son especialmente necesarias nuevas estrategias para mejorar su abordaje, con un enfoque personalizado a cada paciente y desde una perspectiva multidisciplinar, además de integrar las nuevas prácticas de telemedicina y telefarmacia impulsadas a raíz de la pandemia de COVID-19. En este contexto se ha desarrollado el proyecto TEAM 2.0 («Trabajo en Equipos de Asma Multidisciplinares»), continuación del proyecto TEAM llevado a cabo en 2019, con el objetivo de actualizar y priorizar buenas prácticas de trabajo multidisciplinar en AGNC en un contexto post pandemia y analizar los avances conseguidos. Un grupo coordinador, constituido por 8 equipos multidisciplinares de farmacéuticos hospitalarios, neumólogos y alergólogos, llevó a cabo una revisión bibliográfica actualizada, puesta en común de buenas prácticas multidisciplinares y análisis de avances. A través de 5 reuniones regionales con otros expertos con experiencia en AGNC, se compartieron las buenas prácticas identificadas y fueron sometidas a debate, evaluación y priorización. En total, 23 buenas prácticas de trabajo multidisciplinar en AGNC, agrupadas en 5 ámbitos de trabajo: 1) organización del trabajo en equipos multidisciplinares, 2) educación al paciente, autoadministración y adherencia, 3) resultados en salud, seguimiento de datos y persistencia, 4) telefarmacia y experiencias implantadas durante la pandemia de COVID-19 y 5) formación e investigación, fueron evaluadas y priorizadas por 57 profesionales del ámbito de la farmacia hospitalaria, la neumología, la alergología y la enfermería. Este trabajo ha permitido actualizar la hoja de ruta de acciones prioritarias, para seguir avanzando en modelos óptimos de atención al paciente con AGNC en un contexto post-COVID-19. (AU)

Asthma is a chronic respiratory disease with a high health, social and economic impact, particularly in the case of Severe Uncontrolled Asthma (SUA). For this reason, new strategies are especially necessary to improve its approach, with a personalized approach to each patient and from a multidisciplinary perspective, in addition to integrating the new telemedicine and telepharmacy practices promoted as a result of the COVID-19 pandemic. In this context, the TEAM 2.0 project (“Work in Multidisciplinary Asthma Teams”) has been developed, following the TEAM project carried out in 2019, with the aim of updating and prioritizing good multidisciplinary work practices in SUA in a post pandemic context and analyze the progress made. A coordinating group, made up of eight multidisciplinary teams of hospital pharmacists, pulmonologists, and allergists, carried out an updated bibliographic review, sharing of good multidisciplinary practices, and analysis of advances. Through five regional meetings with other experts with experience in SUA, the good practices identified were shared and subjected to debate, evaluation and prioritization. In total, 23 good multidisciplinary work practices in SUA, grouped into five work areas: 1) Organization of work in multidisciplinary teams, 2) Patient education, self-management and adherence, 3) Health results, data monitoring and persistence, 4) Telepharmacy and experiences implemented during the COVID-19 pandemic and 5) Training and research, were evaluated and prioritized by 57 professionals from the field of Hospital Pharmacy, Pulmonology, Allergology and Nursing.

The school-life balance effect on acquiring cross-disciplinary competences in VET: disruption or continuity during COVID-19?

Considering that teleworking and online training are on the rise following the pandemic, studying how school-life balance affects the development of VET competences in online learning during COVID-19 can provide relevant information to enhance educational equity in the future. A longitudinal study was conducted employing an on-line questionnaire to meet the following aims: to explore the development of cross-disciplinary competences in VET during COVID-19; to identify different students' profiles according to their school-life balance during the pandemic; and, to analyse whether the school-life balance was affecting competency development and propose improvements to training as a result. Results show that cross-disciplinary competences did not undergo important changes between the pre-pandemic scenario and during it, except for a decrease in metacognitive self-regulation. Similarly, most students reported having spent the same time studying before and during the pandemic. However, three main profiles of students are revealed, highlighting certain school-life imbalances. While all agree that remote teaching was critical in coping with the situation, differences were found by age and gender, with some participants experiencing more challenging situations. These results provide a fertile context for VET designers and teachers to generate new learning scenarios that meet all students' potential needs.

Universidad y discapacidad intelectual: aportes a la calidad de vida según las percepciones de estudiantes y padres de un contexto chileno / University and Intellectual Disability: Contributions to Quality of Life According to the Perceptionsof Students and Parents in a Chilean Context

La finalización de la educación postsecundaria se asocia con un mejor acceso al empleo y es una forma importante de incrementar los índices de calidad de vida de las personas con discapacidad intelectual; y aun cuando los programa universitarios inclusivos han aumentado en todo el mundo, se sabe poco acerca de cómo estos impactan directamente en la calidad de vida de los estudiantes con DI. Objetivo: Conocer cómo la participación en un programa universitario para estudiantes con discapacidad intelectual contribuye a su calidad de vida. Método: Se aplicó la Escala Integral de CDV para personas con DI y del Desarrollo y se analizan los resultados considerando variables de curso, rol y género de los participantes. Resultados: Se observa un incremento en todas las dimensiones de la CDV y en el índice total en los cursos superiores. Los padres evalúan con mejores puntajes todas las dimensiones de la CDV que los estudiantes. Ambos grupos (estudiantes y sus padres) creen que el programa ha contribuido a la mejora de la calidad de vida y manifiestan que hacen falta mayores instancias de participación con pares sin discapacidad. (AU)

Completion of post-secondary education is associated with better access to employment and is an important way of increasing quality of life rates for people with intellectual disabilities; and even though inclusive university programs have increased around the world, little is known about how they directly impact the quality of life of students with ID. Target: Know how participation in a university program for students with intellectual disabilities contributes to their quality of life. Method: The Compre-hensive QOL Scale for people with ID and Development was applied and the results were analyzed considering variables of course, role and gender of the participants. Re-sults: An increase is observed in all the dimensions of the QOL and in the total index in the higher courses. Parents evaluate all QOL dimensions with better scores than stu-dents. Both groups (students and their parents) believe that the program has contributed to improving the quality of life and state that greater instances of participation with non-disabled peers are needed.

Intention to Transfer and Transfer Following eLearning in Spain.

Understanding vocational learning and transfer is vital to European citizens. We need to understand how transfer works, which factors influence it, and how these factors affect employee behaviour. Research in online training specific to Southern Europe is needed to move the field forward. The Unified Model of Motivation for Training Transfer (MTT) was proposed to understand behaviour change after training. It conceives three phases: (1) forming transfer intentions, (2) actualizing implementation intentions for transfer, and (3) strengthening transfer commitment. We analysed initial transfer intention and transfer following online training in three Spanish organisations. We used an ex post facto prospective design with one group (n = 204). We applied the online version of the Initial Transfer Intention questionnaire (ITI) three days before the training, and the Transfer Questionnaire (TrQ) three to four months after the training. Training consisted of 22 online courses offered by the three participating organisations. A cluster analysis and post hoc analysis were performed. We identified three groups (k = 3), indicating that there were significant differences in the means between employees with low and high intention to transfer. Results showed a greater difference in the factor profile between participants with LowPT and HighPT. We identified common characteristics among people with low levels of transfer; this information can help understand what type of employee will transfer less and provide cues on how to prevent this from happening in future training activities. Limitations and recommendations for research and practice are discussed.

Incidence of pulmonary embolism in patients with non-invasive respiratory support during COVID-19 outbreak.

While the incidence of thrombotic complications in critically ill patients is very high, in patients under non-invasive respiratory support (NIS) is still unknown. The specific incidence of thrombotic events in each of the clinical scenarios within the broad spectrum of severity of COVID-19, is not clearly established, and this has not allowed the implementation of thromboprophylaxis or anticoagulation for routine care in COVID-19. Patients admitted in a semi-critical unit treated initially with NIS, especially Continuous-Positive Airway Pressure (CPAP), were included in the study. The cumulative incidence of pulmonary embolism was analyzed and compared between patients with good response to NIS and patients with clinical deterioration that required orotracheal intubation. 93 patients were included and 16% required mechanical ventilation (MV) after the NIS. The crude cumulative incidence of the PE was 14% (95%, CI 8-22) for all group. In patients that required orotracheal intubation and MV, the cumulative incidence was significantly higher [33% (95%, CI 16-58)] compared to patients that continued with non-invasive support [11% (CI 5-18)] (Log-Rank, p = 0.013). Patients that required mechanical ventilation were at higher risk of PE for a HR of 4.3 (95%CI 1.2-16). In conclusion, cumulative incidence of PE is remarkably higher in critically patients with a potential impact in COVID-19 evolution. In this context, patients under NIS are a very high-risk group for developing PE without a clear strategy regarding thromboprophylaxis.

As one of the most prevalent chronic respiratory diseases, asthma imposes a heavy health and socioeconomic burden on society, particularly in the case of patients who fail to appropriately control the disease. For this reason, improving the clinical management of patients with severe uncontrolled asthma should be a priority for any healthcare system. At a time when healthcare models for chronic disease management and personalized medicine are undergoing a major overhaul, the project presented in this study seeks to lay the foundations for an interdisciplinary care model for patients with severe uncontrolled asthma. The work carried out reinforces the general perception that it is paramount to optimize coordination between different levels of care, encourage collaboration and an interdisciplinary approach, and promote an integrated care model that makes it possible to adapt the care of patients with severe uncontrolled asthma in a more personalized manner. Under this project, a series of interdisciplinary working groups were created, made up of specialist hospital pharmacists, pneumologists and allergists, to identify and prioritize a number of best practices, and classify them in terms of their potential impact on the improvement of the quality of care and the health outcomes of patients with severe uncontrolled asthma, and their feasibility. The authors' ambition is that the conclusions drawn from this study should help other interdisciplinary teams improve the care provided to patients suffering from severe uncontrolled asthma

Temporal groups of lineage-related neurons have different neuropeptidergic fates and related functions in the Drosophila melanogaster CNS.

The central nervous system (CNS) of Drosophila is comprised of the brain and the ventral nerve cord (VNC), which are the homologous structures of the vertebrate brain and the spinal cord, respectively. Neurons of the CNS arise from neural stem cells called neuroblasts (NBs). Each neuroblast gives rise to a specific repertory of cell types whose fate is unknown in most lineages. A combination of spatial and temporal genetic cues defines the fate of each neuron. We studied the origin and specification of a group of peptidergic neurons present in several abdominal segments of the larval VNC that are characterized by the expression of the neuropeptide GPB5, the GPB5-expressing neurons (GPB5-ENs). Our data reveal that the progenitor NB that generates the GPB5-ENs also generates the abdominal leucokinergic neurons (ABLKs) in two different temporal windows. We also show that these two set of neurons share the same axonal projections in larvae and in adults and, as previously suggested, may both function in hydrosaline regulation. Our genetic analysis of potential specification determinants reveals that Klumpfuss (klu) and huckebein (hkb) are involved in the specification of the GPB5 cell fate. Additionally, we show that GPB5-ENs have a role in starvation resistance and longevity; however, their role in desiccation and ionic stress resistance is not as clear. We hypothesize that the neurons arising from the same neuroblast lineage are both architecturally similar and functionally related.

Online vs. Classroom Learning: Examining Motivational and Self-Regulated Learning Strategies Among Vocational Education and Training Students.

Numerous studies have been conducted to explore students' employment of motivational and self-regulated learning strategies (SRL). Research highlights the importance of having motivated students equipped with strategies that help them self-regulate their learning, this being highly important when learning is acquired through online learning programs. Nonetheless, such research has been scarce with Vocational Education and Training (VET) students; this is the gap in the literature this paper aims to address. The article analyzes the degree to which VET students employ motivational and SRL strategies by comparing them according to the learning mode chosen. To achieve this, a quantitative approach was adopted to carry out a cross-sectional study. A total of 577 first-year VET students responded to an online questionnaire based on some of the motivational and SRL strategies scale included in Pintrich's model. Statistical analyses were applied to test two hypotheses. Pintrich's model was validated through a confirmatory factor analysis considering its application to Catalan VET students for the first time. The results reveal significant differences between classroom and online students in terms of levels of metacognitive self-regulation and effort regulation when starting a VET program. However, this difference might not be entirely explained by the learning mode chosen. The findings of this study will provide VET researchers and practitioners with a greater understanding of their students' characteristics when starting the program and the means to develop strategies that ensure their engagement throughout the course.

Variability in the number of abdominal leucokinergic neurons in adult Drosophila melanogaster.

Developmental plasticity allows individuals with the same genotype to show different phenotypes in response to environmental changes. An example of this is how neuronal diversity is protected at the expense of neuronal number under sustained undernourishment during the development of the Drosophila optic lobe. In the development of the Drosophila central nervous system, neuroblasts go through two phases of neurogenesis separated by a period of mitotic quiescence. Although during embryonic development much evidence indicates that both cell number and the cell fates generated by each neuroblast are very precisely controlled in a cell autonomous manner, after quiescence extrinsic factors control the reactivation of neuroblast proliferation in a fashion that has not yet been elucidated. Moreover, there is very little information about whether environmental changes affect lineage progression during postembryonic neurogenesis. Using as a model system the pattern of abdominal leucokinergic neurons (ABLKs), we have analyzed how changes in a set of environmental factors affect the number of ABLKs generated during postembryonic neurogenesis. We describe the variability in ABLK number between individuals and between hemiganglia of the same individual and, by genetic analysis, we identify the bithorax-complex genes and the ecdysone hormone as critical factors in these differences. We also explore the possible adaptive roles involved in this process. J. Comp. Neurol. 525:639-660, 2017. © 2016 Wiley Periodicals, Inc.

Hexokinase 2 Is an Intracellular Glucose Sensor of Yeast Cells That Maintains the Structure and Activity of Mig1 Protein Repressor Complex.

Hexokinase 2 (Hxk2) fromSaccharomyces cerevisiaeis a bi-functional enzyme, being both a catalyst in the cytosol and an important regulator of the glucose repression signal in the nucleus. Despite considerable recent progress, little is known about the regulatory mechanism that controls nuclear Hxk2 association with theSUC2promoter chromatin and how this association is necessary forSUC2gene repression. Our data indicate that in theSUC2promoter context, Hxk2 functions through a variety of structurally unrelated factors, mainly the DNA-binding Mig1 and Mig2 repressors and the regulatory Snf1 and Reg1 factors. Hxk2 sustains the repressor complex architecture maintaining transcriptional repression at theSUC2gene. Using chromatin immunoprecipitation assays, we discovered that the Hxk2 in its open configuration, at low glucose conditions, leaves the repressor complex that induces its dissociation and promotesSUC2gene expression. In high glucose conditions, Hxk2 adopts a close conformation that promotes Hxk2 binding to the Mig1 protein and the reassembly of theSUC2repressor complex. Additional findings highlight the possibility that Hxk2 constitutes an intracellular glucose sensor that operates by changing its conformation in response to cytoplasmic glucose levels that regulate its interaction with Mig1 and thus its recruitment to the repressor complex of theSUC2promoter. Thus, our data indicate that Hxk2 is more intimately involved in gene regulation than previously thought.

Type 2 diabetes, obesity, and sex difference affect the fate of glucose in the human heart.

Type 2 diabetes, obesity, and sex difference affect myocardial glucose uptake and utilization. However, their effect on the intramyocellular fate of glucose in humans has been unknown. How the heart uses glucose is important, because it affects energy production and oxygen efficiency, which in turn affect heart function and adaptability. We hypothesized that type 2 diabetes, sex difference, and obesity affect myocardial glucose oxidation, glycolysis, and glycogen production. In a first-in-human study, we measured intramyocardiocellular glucose metabolism from time-activity curves generated from previously obtained positron emission tomography scans of 110 subjects in 3 groups: nonobese, obese, and diabetes. Group and sex difference interacted in the prediction of all glucose uptake, utilization, and metabolism rates. Group independently predicted fractional glucose uptake and its components: glycolysis, glycogen deposition, and glucose oxidation rates. Sex difference predicted glycolysis rates. However, there were fewer differences in glucose metabolism between diabetic patients and others when plasma glucose levels were included in the modeling. The potentially detrimental effects of obesity and diabetes on myocardial glucose metabolism are more pronounced in men than women. This sex difference dimorphism needs to be taken into account in the design, trials, and application of metabolic modulator therapy. Slightly higher plasma glucose levels improve depressed glucose oxidation and glycogen deposition rates in diabetic patients.

Origin and specification of the brain leucokinergic neurons of Drosophila: similarities to and differences from abdominal leucokinergic neurons.

BACKGROUND: The Drosophila central nervous system contains many types of neurons that are derived from a limited number of progenitors as evidenced in the ventral ganglion. The situation is much more complex in the developing brain. The main neuronal structures in the adult brain are generated in the larval neurogenesis, although the basic neuropil structures are already laid down during embryogenesis. The embryonic factors involved in adult neuron origin are largely unknown. To shed light on how brain cell diversity is achieved, we studied the early temporal and spatial cues involved in the specification of lateral horn leucokinin peptidergic neurons (LHLKs). RESULTS: Our analysis revealed that these neurons have an embryonic origin. We identified their progenitor neuroblast as Pcd6 in the Technau and Urbach terminology. Evidence was obtained that a temporal series involving the transcription factors Kr, Pdm, and Cas participates in the genesis of the LHLK lineage, the Castor window being the one in which the LHLKs neurons are generated. It was also shown that Notch signalling and Dimmed are involved in the specification of the LHLKs. CONCLUSIONS: Serial homologies with the origin and factors involved in specification of the abdominal leucokinergic neurons (ABLKs) have been detected.

Pilot study of pioglitazone and exercise training effects on basal myocardial substrate metabolism and left ventricular function in HIV-positive individuals with metabolic complications.

BACKGROUND: Individuals with HIV infection and peripheral metabolic complications have impaired basal myocardial insulin sensitivity that is related to left ventricular (LV) diastolic dysfunction. It is unknown whether interventions shown to be effective in improving peripheral insulin sensitivity can improve basal myocardial insulin sensitivity and diastolic function in people with HIV and peripheral metabolic complications. OBJECTIVE: In a pilot study, we evaluated whether the peroxisome proliferator-activated receptor-gamma (PPAR-γ) agonist pioglitazone or combined endurance and resistance exercise training improves basal myocardial insulin sensitivity and diastolic function in HIV+ adults with peripheral metabolic complications. DESIGN: Twenty-four HIV+ adults with metabolic complications including peripheral insulin resistance were randomly assigned to 4 months of pioglitazone (PIO; 30 mg/d) or supervised, progressive endurance and resistance exercise training (EXS; 90-120 min/d, 3 d/wk). Basal myocardial substrate metabolism was quantified by radioisotope tracer methodology and positron emission tomography (PET) imaging, and LV function was measured by echocardiography. RESULTS: Twenty participants completed the study. Neither PIO nor EXS resulted in a detectable improvement in basal myocardial insulin sensitivity or diastolic function. Post hoc analyses revealed sample sizes of more than 100 participants are needed to detect significant effects of these interventions on basal myocardial insulin sensitivity and function. CONCLUSIONS: PIO or EXS alone did not significantly increase basal myocardial insulin sensitivity or LV diastolic function in HIV+ individuals with peripheral metabolic complications.
