Physical activity among adolescent girls and the factors linked to it: a scoping review

The low level of physical activity in Western countries is one of the major public health problems of the 21st century, and the problem is especially dire among adolescent girls, worsens their health and increases social inequality. The objective was to identify the factors linked to the initiation, maintenance, and abandonment of physical activity among adolescent girls. A scoping review of the literature was conducted in PubMed, CINAHL, Cochrane Library, SCOPUS and Web of Science databases. Studies published 2006-2020 were included in the search and the keywords used were Adolescent girls, Physical activity, Experience and the boolean operator AND. The studies reflected psychosocial factors, perceptions, or experiences of adolescent girls linked to physical activity. Both quantitative and qualitative research from any discipline were included. Forty-two studies were selected. Using Pender's health promotion model to evaluate the results, we conclude that perception of barriers and situational factors are the main reasons for low levels of physical activity. Perceived self-efficacy, positive affect linked to the activity, and the physical and social environment are the key to starting and maintaining physical activity. These factors should be kept in mind in designing health promotion plans that aim to increase physical activity in adolescent girls

Implementation of advanced triage in the Emergency Department of high complexity public hospital: Research protocol

Aim: To evaluate the efficacy of advanced nurse triage based on the quality of care outcomes of patients attending the Emergency Department of a high-complexity hospital. To analyse the concept of advanced triage and the essential elements of the construct. Design: Mixed longitudinal study, divided into 4 steps; which will include an initial qualitative step, two observational studies and finally, a quasi-experimental study. Clinical trial registration number: NCT05230108. Methods: Step 1 will consist of a concept analysis. Step 2 will include a mapping of advanced practice protocol terminologies. Step 3 will analyse the opinion of health professionals on advanced triage. In step 4: in the retrospective phase (n = 1095), sociodemographic and clinical variables and quality indicators such as waiting time will be analysed. After that, in the prospective phase (n = 547), advanced triage will be implemented and the two cohorts will be compared. The whole study will be carried out from January 2022 to January 2024. Discussion: Patients classified as low complexity at triage are more vulnerable to emergency department overcrowding. The implementation of advanced triage would make it possible to respond to patient needs by offering equitable and quality healthcare, facilitating accessibility, safety and humanization of the emergency department

Wastewater based epidemiology beyond SARS-CoV-2: Spanish wastewater reveals the current spread of Monkeypox virus

Besides nasopharyngeal swabs, monkeypox virus (MPXV) DNA has been detected in a variety of samples such as saliva, semen, urine and fecal samples. Using the environmental surveillance network previously developed in Spain for the routine wastewater surveillance of SARS-CoV-2 (VATar COVID-19), we have analyzed the presence of MPXV DNA in wastewater from different areas of Spain. Samples (n=312) from 24 different wastewater treatment plants were obtained between May 9 (week 22_19) and August 4 (week 22_31), 2022. Following concentration of viral particles by flocculation, a qPCR procedure allowed us to detect MPXV DNA in 63 wastewater samples collected from May 16 to August 4, 2022, with values ranging between 2.2 per 103 to 8.7 per 104 genome copies (gc)/L. This study shows that MPXV DNA can be reproducibly detected by qPCR in longitudinal samples collected from different Spanish wastewater treatment plants. According to data from the National Epidemiological Surveillance Network (RENAVE) in Spain a total of 6,119 cases have been confirmed as of August 19, 2022. However, and based on the wastewater data, the reported clinical cases seem to be underestimated and asymptomatic infections may be more frequent than expected.his research was supported by the European Commission NextGenerationEU fund, through CSIC's Global Health Platform (PTI Salud Global) and samples were obtained from the COVID-19 wastewater surveillance project (VATar COVID-19) funded by the Spanish Ministry for the Ecological Transition and the Demographic Challenge and the Spanish Ministry of Health.

Monitoring emergence of SARS-CoV-2 B.1.1.7 Variant through the Spanish National SARS-CoV-2 Wastewater Surveillance System (VATar COVID-19) from December 2020 to March 2021

Background Since its first identification in the United Kingdom in late 2020, the highly transmissible B.1.1.7 variant of SARS-CoV-2, become dominant in several European countries raising great concern. Aim The aim of this study was to develop a duplex real-time RT-qPCR assay to detect, discriminate and quantitate SARS-CoV-2 variants containing one of its mutation signatures, the ΔHV69/70 deletion, to trace the community circulation of the B.1.1.7 variant in Spain through the Spanish National SARS-CoV-2 Wastewater Surveillance System (VATar COVID-19). Results B.1.1.7 variant was first detected in sewage from the Southern city of Málaga (Andalucía) in week 20_52, and multiple introductions during Christmas holidays were inferred in different parts of the country, earlier than clinical epidemiological reporting by the local authorities. Wastewater-based B.1.1.7 tracking showed a good correlation with clinical data and provided information at the local level. Data from WWTPs which reached B.1.1.7 prevalences higher than 90% for ≥ 2 consecutive weeks showed that 8.1±1.8 weeks were required for B.1.1.7 to become dominant. Conclusion The study highlights the applicability of RT-qPCR-based strategies to track specific mutations of variants of concern (VOCs) as soon as they are identified by clinical sequencing, and its integration into existing wastewater surveillance programs, as a cost-effective approach to complement clinical testing during the COVID-19 pandemic.This work was partially supported by the COVID-19 wastewater surveillance project (VATar COVID19), funded by the Spanish Ministry for the Ecological Transition and the Demographic Challenge of and the Spanish Ministry of Health; grants from CSIC (202070E101) and MICINN co-founded by AEI FEDER, UE (AGL2017-82909); grant ED431C 2018/18 from the Conselleria de Educacion, Universidade e Formacion Profesional, Xunta de Galicia (Spain); Direccio General de Recerca i Innovacio en Salut (DGRIS) Catalan Health Ministry Generalitat de Catalunya through Vall de Hebron Research Institute (VHIR), and Centro para el Desarrollo Tecnologico Industrial (CDTI) from the Spanish Ministry of Economy and Business, grant number IDI-20200297.

Recovering coronavirus from large volumes of water

The need for monitoring tools to better control the ongoing coronavirus disease (COVID-19) pandemic is extremely urgent and the contamination of water resources by excreted viral particles poses alarming questions to be answered. As a first step to overcome technical limitations in monitoring SARS-CoV-2 along the water cycle, we assessed the analytical performance of a dead end hollow fiber ultrafiltration coupled to different options for secondary concentrations to concentrate viral particles from large volume of spiked tap water, seawater and surface water together with two quantitative RT-qPCR detection kits. Spiking the porcine epidemic diarrhea virus (PEDV), an enveloped virus surrogate for SARS-CoV-2, together with the mengovirus, we demonstrated that PEG-precipitation and SENS-kit better recovered PEDV (13.10 ± 0.66%) from tap water, while centrifugal filtration resulted the best option to recover mengovirus regardless of the detection kit used. No statistical significant differences were found when comparing high (10,000 ×g) and low (3500 ×g) centrifugation speeds for the secondary PEG- based concentration of spiked seawater, while considerable inhibition was observed for both viruses detected by NoInh-kit assay. Similarly, the co-concentration of PCR inhibitors and viral particles was observed in surface waters detected with either SENS-kit or NoInh-kit and RNA dilution was needed to achieve acceptable recoveries at the expenses of the overall sensitivity of the method. These methodologies represent suitable options to investigate SARS-CoV-2 occurrence in different water resources and allow to conduct on site sampling of large volume of water.The study was funded by grants from CSIC (202070E101), Generalitat Valenciana (Covid_19-SCI), and MICIU co-founded by AEI/FEDER, UE (AGL2017-82909).
