Objective To assess the outcomes of a contact-tracing programme to increase the diagnosis of tuberculosis in Cubal, Angola and offer preventive treatment to high-risk groups. Methods A health centre-based contact-tracing programme was launched in Hospital Nossa Senhora da Paz in March 2015 and we followed the programme until 2022. In that time, staffing and testing varied which we categorized as four periods: medical staff reinforcement, 2015-2017, with a doctor seconded from Vall d'Hebron University Hospital, Spain; routine staff, 2017-2021, with no external medical support; community directly observed treatment (DOT), 2018-2019 with community worker support; and enhanced contact tracing, 2021-2022, with funding that allowed free chest radiographs, molecular and gastric aspirate testing. We assessed differences in contacts seen each month, and testing and treatment offered across the four periods. Findings Overall, the programme evaluated 1978 contacts from 969 index cases. Participation in the programme was low, although it increased significantly during the community DOT period. Only 16.6% (329/1978) of contacts had a chest radiograph. Microbiological confirmation increased to 72.2% (26/36) after including molecular testing, and 10.1% (200/1978) of contacts received treatment for tuberculosis. Of 457 contacts younger than 5 years, 36 (7.9%) received preventive tuberculosis treatment. Half of the contacts were lost to follow-up before a final decision was taken on treatment. Conclusion Contact tracing increased the diagnosis of tuberculosis although engagement with the programme was low and loss to follow-up was high. Participation increased during community DOT. Community-based screening should be explored to improve participation and diagnosis. Objectif Evaluer l'efficacite d'un programme de suivi des contacts pour ameliorer le depistage de la tuberculose a Cubal, en Angola, et proposer un traitement preventif aux groupes a haut risque. Methodes Un programme de suivi des contacts en centre de sante a ete lance en mars 2015 a l'Hospital Nossa Senhora da Paz, et nous l'avons accompagne jusqu'en 2022. Comme les effectifs et le depistage ont evolue durant cette periode, nous l'avons divisee en quatre phases: renforcement de l'equipe medicale entre 2015 et 2017, avec un medecin detache de l'hopital universitaire Vall d'Hebron, en Espagne; personnel regulier entre 2017 et 2021, sans assistance medicale externe; traitement sous surveillance directe (TSD) au niveau communautaire entre 2018 et 2019, avec l'aide des agents communautaires; et enfin, suivi renforce des contacts entre 2021 et 2022, avec un financement permettant d'effectuer gratuitement des radiographies thoraciques, ainsi que des tests moleculaires et d'aspiration gastrique. Nous avons evalue les differences dans les contacts vus chaque mois, mais aussi dans les tests et traitements proposes durant les quatre phases. Resultats Au total, le programme a examine 1978 contacts Issus de 969 cas Indicateurs. La participation au programme etait faible, bien qu'elle ait considerablement augmente au cours de la phase de TSD au niveau communautaire. A peine 16,6% (329/1978) des contacts ont fait l'objet d'une radiographie thoracique. La confirmation microbiologique a atteint 72,2% (26/36) apres avoir inclus les tests moleculaires, tandis que 10,1% (200/1978) des contacts ont recu un traitement contre la tuberculose. Sur les 457 contacts ages de moins de 5 ans, 36 (7,9%) se sont vus administrer un traitement preventif contre la tuberculose. La moitie des contacts ont ete perdus de vue avant qu'une decision finale n'ait ete prise en matiere de traitement. Conclusion Le suivi a permis de mieux diagnostiquer la tuberculose, malgre la faible participation au programme et le nombre eleve de contacts perdus de vue. La participation a augmente pendant la phase de TSD au niveau communautaire. Le depistage au niveau communautaire devrait etre renforce afin d'accroitre le taux de participation et de diagnostic. Objetivo Evaluar los resultados de un programa de rastreo de contactos para aumentar el diagnostico de la tuberculosis en Cubal (Angola) y ofrecer tratamiento preventivo a los grupos de alto riesgo. Metodos En marzo de 2015, se inicio un programa de rastreo de contactos basado en centros sanitarios en el Hospital Nossa Senhora da Paz y se siguio hasta 2022. En ese tiempo, la dotacion de personal y las pruebas variaron, lo que clasificamos en cuatro periodos: refuerzo del personal medico, de 2015 a 2017, con un medico enviado en comision de servicios desde el Hospital Universitario Vall d'Hebron (Espana); personal de rutina, de 2017 a 2021, sin apoyo medico externo; tratamiento directamente observado (TDO) en la poblacion, de 2018 a 2019, con apoyo de trabajadores comunitarios; y rastreo de contactos mejorado, de 2021 a 2022, con financiacion que permitio realizar radiografias de torax y pruebas moleculares y de aspirado gastrico gratuitas. Se evaluaron las diferencias en los contactos atendidos al mes y las pruebas y el tratamiento ofrecidos en los cuatro periodos. Resultados En total, el programa evaluo 1978 contactos de 969 casos de referencia. La participacion en el programa fue baja, aunque aumento de manera significativa durante el periodo de TDO en la poblacion. Solo el 16,6% (329/1978) de los contactos se sometieron a una radiografia de torax. La confirmacion microbiologica aumento al 72,2% (26/36) tras incluir las pruebas moleculares y el 10,1% (200/1978) de los contactos recibieron tratamiento para la tuberculosis. De 457 contactos menores de 5 anos, 36 (7,9%) recibieron tratamiento preventivo contra la tuberculosis. Se perdio el seguimiento de la mitad de los contactos antes de que se tomara una decision final sobre el tratamiento. Conclusion El rastreo de contactos aumento el diagnostico de la tuberculosis, aunque el compromiso con el programa fue bajo y la perdida del seguimiento fue alta. La participacion aumento durante el TDO en la poblacion. Se debe explorar el cribado en la poblacion para mejorar la participacion y el diagnostico., Introduction Increasing testing and diagnosis of tuberculosis (TB) is one of the main pillars of the End TB Strategy, together with rapid initiation of effective therapy and follow-up programmes.

Social networks have become pivotal in education, offering opportunities for inclusive learning experiences. This study seeks to understand the role of social networks in educational inclusion by analyzing students’ usage, motivations, and perceived benefits. It focuses on identifying usage patterns, main activities, and perceptions regarding the impact of social networks on communication, interpersonal relationships, and access to educational information. A quantitative approach was employed, gathering data through a questionnaire from 355 university students of the specialty of secondary education in Lima during the 2023-2 semester. Statistics on social media usage, predominant activities, and perceived benefits associated with their use were analyzed. Findings revealed high social media usage, with WhatsApp (96,7 %) being the most used platform, followed by Facebook (63,6 %) and Instagram (40,5 %). Main activities were entertainment (66,4 %), family communication (60,9 %), and education (58,1 %). Students also valued improved interpersonal relationships (32,6 %) and access to information (68,7 %). Social networks play a crucial role in educational inclusion, providing opportunities for communication, collaboration, and information access. The need to balance their use and address challenges like digital dependency, prioritizing student well-being in the digital age, is emphasized. [ABSTRACT FROM AUTHOR]

The development of novel technologies to mitigate the effects of climate change through Smart Grids requires energy related data. Unfortunately, this type of data is not always available in Mexico, especially from non-large urban areas and at the household level. Therefore, we present a dataset that contains electrical demand and consumption time series of 5 households within a small community in Mexico, at various resolutions, as well as weather data. The electrical demand is given in 15 min resolution, while the electrical consumption is presented in both hourly and daily resolutions. The data is contained within 15 separate .csv files; one for each household's resolution. In turn, the weather data is given in two .csv files (for outdoor and indoor variables, respectively) that together contain 24 meteorological variables measured in a 5 min resolution that is not always consistent. The dataset comprises of two separate folders that contain either the electrical demand and consumption files or the weather files. This dataset could aid in the development of novel smart grid methods and algorithms that might be able to push the energy transition in Mexico and other developing countries forward., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Author(s).)

The aphid Chaetosiphon fragaefolii Cockerell, 1901 is an agricultural pest and known vector of strawberry viruses. To better understand its biology and systematics, we performed a genomic analysis on C. fragaefolii collected from Quinalt strawberry plants from Pacific Grove, Monterey county, California, USA using Oxford Nanopore and Illumina sequencing. The resulting data were used to assemble the aphids complete mitogenome. The mitogenome of C. fragaefolii is 16,108 bp in length and contains 2 rRNA, 13 protein-coding, and 22 tRNA genes (GenBank accession number LC590896). The mitogenome is similar in content and organization to other Aphididae. Phylogenetic analysis of the C. fragaefolii mitogenome resolved it in a fully supported clade in the tribe Macrosiphini. Analysis of the cox1 barcode sequence of C. fragaefolii from California found exact and nearly identical sequences to C. fragaefolii and Chaetosiphon thomasi Hille Ris Lambers, 1953, suggesting the two species are conspecific., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2021 The Author(s).
