ABSTRACT: Heat stress (HS) is one of the pivotal causes of economic losses in dairy industries and affects welfare and performance, but its effect on milk microbiota remains elusive. It is also unclear if and how different breeds may cope with HS in sustaining productive performance. The objectives of this study were to compare (1) the performance of 2 dairy breeds, namely Holstein and Brown Swiss, subjected to HS and (2) the different effects of HS on the milk microbiota of the 2 breeds in thermal comfort conditions and HS. The study was carried out on 36 dairy cows, 18 per breed. The HS was induced by switching off the cooling system during a natural heat wave for 4 d. In addition to the temperature-humidity index, animal stress was confirmed by measuring respiratory frequency and rectal temperature twice daily at 0400 h and 1500 h. The HS affected the 2 breeds differently. The rectal temperature increased with HS in both breeds. Milk yield recording and sampling were performed during the morning milking of d 1 (at 0400 h) and afternoon milking of d 4 (at 1700 h). Productive parameters were also different: milk yield, FCM, ECM, protein and casein content, and renneting parameters were decreased in Holstein cows but remained unaffected in Brown Swiss cows. The HS also modified the milk microbiota of the 2 breeds differently. During HS, the Brown Swiss cows had milk microbiota that was richer (α diversity) than that of the Holstein cows. Comparing the time points before and during HS within breeds showed that Brown Swiss cow milk microbiota was less affected by HS than Holstein cow milk microbiota. Under the same thermal comfort condition, milk microbiota did not discriminate between Brown Swiss and Holstein. Consistently with α and β diversity, the number of operational taxonomic units (OTU) at the genus level that changed their abundance during HS was higher in Holstein (74 OTU) than in Brown Swiss (only 20 OTU). The most significant changes in abundance affected Acinetobacter, Chryseobacterium, Cutibacterium, Enterococcus, Lactococcus, Prevotella-9, Serratia, and Streptococcus. In conclusion, the present report confirms and extends previous studies by demonstrating that Brown Swiss cows regulate their body temperature better than the Holstein breed. The relative thermal tolerance to HS compared with Holstein cows is also confirmed by changes in milk uncultured microbiota, which were more evident in Holstein cows than in Brown Swiss cows.

This study investigated the involvement of Italian preschool and primary school teachers in outdoor education and scouting activities and their association with student cooperation and personal care. While outdoor education has various psychophysiological, psychosocial, social, and pedagogical benefits, some teachers express concerns about their readiness to implement such activities. We hypothesized that preschool teachers are more willing to participate in outdoor education and scouting than primary school teachers. We also hypothesized that outdoor education teachers would score higher in all survey items compared to regular teachers (see Table 2). The results indicated no significant difference between preschool and primary school teachers. However, there were differences in the survey items between outdoor education and regular teachers, except for item 11. The study suggests that providing appropriate instruction and teaching tools to teachers, their students' schooling experiences and skills are likely to improve.

Background: Physical Education (PE) classes are vital for nurturing students' social development and promoting collaboration. This study examined how primary and middle school students perceived PE classes, with a focus on collaboration, well-being and enjoyment, teacher behavior, the inclusion of nondisabled and disabled students, and general class behavior. Methods: One-hundred and seventy students (24 primary school and 146 middle school students) were surveyed using a questionnaire. Results: Exploratory Factor Analysis identified seven factors including: well-being, activities for all students, teacher-oriented behavior, collaboration, and attention to students with disabilities. Linear regressions on each identified Factor revealed higher well-being (Factor 1) between primary and middle school students. In addition, the perceived well-being in PE classes and staying together with classmates among younger middle school students was found to be higher than that reported by their older counterparts in middle school. The analysis also revealed that males perceived a higher well-being in PE classes than females. Conclusion: The research underscores that primary and especially middle school PE teachers should promote the well-being of students by creating inclusive and enjoyable PE classes. The PE classes should consider the differences between sexes and the individual differences. Finally, this research lays the foundation for future investigations to refine inclusive PE strategies and improve students' well-being.

ABSTRACT: Citrus pectin (CP) is a dietary fiber used in animal nutrition with anti-inflammatory properties. CP downregulates chicken immunoregulatory monocytes' functions, like chemotaxis and phagocytosis, in vitro. The molecular underlying background is still unknown. This study investigated the activity of CP on chicken peripheral blood mononuclear cells (PBMC) proteome. An overall number of 1503 proteins were identified and quantified. The supervised sparse variant partial least squares—discriminant analysis (sPLS-DA) for paired data highlighted 373 discriminant proteins between CP-treated and the control group, of which 50 proteins with the highest abundance in CP and 137 in the control group were selected for Gene Ontology (GO) analyses using ProteINSIDE. Discriminant Protein highly abundant in CP-treated cells were involved in actin cytoskeleton organization and negative regulation of cell migration.Interestingly, MARCKSL1, a chemotaxis inhibitor, was upregulated in CP-treated cells. On the contrary, CP incubation downregulated MARCKS, LGALS3, and LGALS8, which are involved in cytoskeleton rearrangements, cell migration, and phagocytosis. In conclusion, these results provide a proteomics background to the anti-inflammatory activity of CP, demonstrating that the in vitro downregulation of phagocytosis and chemotaxis is related to changes in proteins related to the cytoskeleton.

Abstract Controlling foodborne pathogens in buffalo milk is crucial for ensuring food safety. This study estimated the prevalence of nine target genes representing seven critical foodborne bacteria in milk and milk products, and identified factors associated with their presence in buffalo milk chain nodes in Bangladesh. One hundred and forty-three milk samples from bulk tank milk (n = 34), middlemen (n = 37), milk collection centers (n = 37), and milk product shops (n = 35) were collected and analyzed using RT-PCR. Escherichia (E.) coli, represented through yccT genes, was the most prevalent throughout the milk chain (81–97%). Chi-squared tests were performed to identify the potential risk factors associated with the presence of foodborne bacteria encoded for different genes. At the middleman level, the prevalence of E. coli was associated with the Mymensingh, Noakhali, and Bhola districts (P = 0.01). The prevalence of Listeria monocytogenes, represented through inlA genes, and Yersinia (Y.) enterocolitica, represented through yst genes, were the highest at the farm level (65–79%). The prevalence of both bacteria in bulk milk was associated with the Noakhali and Bhola districts (P

Abstract Exosomes mediate near and long-distance intercellular communication by transferring their molecular cargo to recipient cells, altering their biological response. Milk exosomes (MEx) are internalized by immune cells and exert immunomodulatory functions in vitro. Porcine MEx can accumulate in the small intestine, rich in macrophages. No information is available on the immunomodulatory ability of porcine MEx on porcine monocytes, which are known precursors of gut macrophages. Therefore, this study aims at (1) assessing the in vitro uptake of porcine MEx by porcine monocytes (CD14+), and (2) evaluating the in vitro impact of porcine MEx on porcine monocytes immune functions. MEx were purified by ultracentrifugation and size exclusion chromatography. The monocytes’ internalization of PKH26-labeled MEx was examined using fluorescence microscopy. Monocytes were incubated with increasing exosome concentrations and their apoptosis and viability were measured. Lastly, the ability of MEx to modulate the cells’ immune activities was evaluated by measuring monocytes’ phagocytosis, the capacity of killing bacteria, chemotaxis, and reactive oxygen species (ROS) production. MEx were internalized by porcine monocytes in vitro. They also decreased their chemotaxis and phagocytosis, and increased ROS production. Altogether, this study provides insights into the role that MEx might play in pigs’ immunity by demonstrating that MEx are internalized by porcine monocytes in vitro and exert immunomodulatory effects on inflammatory functions.

Abstract Staphylococcus aureus modulates the host immune response directly by interacting with the immune cells or indirectly by secreting molecules (secretome). Relevant differences in virulence mechanisms have been reported for the secretome produced by different S. aureus strains. The present study investigated the S. aureus secretome impact on peripheral bovine mononuclear cells (PBMCs) by comparing two S. aureus strains with opposite epidemiological behavior, the genotype B (GTB)/sequence type (ST) 8, associated with a high within-herd prevalence, and GTS/ST398, associated with a low within-herd prevalence. PBMCs were incubated with different concentrations (0%, 0.5%, 1%, and 2.5%) of GTB/ST8 and GTS/ST398 secretome for 18 and 48 h, and the viability was assessed. The mRNA levels of pro- (IL1-β and STAT1) and anti-inflammatory (IL-10, STAT6, and TGF-β) genes, and the amount of pro- (miR-155-5p and miR-125b-5p) and anti-inflammatory (miR-146a and miR-145) miRNAs were quantified by RT-qPCR. Results showed that incubation with 2.5% of GTB/ST8 secretome increased the viability of cells. In contrast, incubation with the GTS/ST398 secretome strongly decreased cell viability, preventing any further assays. The GTB/ST8 secretome promoted PBMC polarization towards the pro-inflammatory phenotype inducing the overexpression of IL1-β, STAT1 and miR-155-5p, while the expression of genes involved in the anti-inflammatory response was not affected. In conclusion, the challenge of PBMC to the GTS/ST398 secretome strongly impaired cell viability, while exposure to the GTB/ST8 secretome increased cell viability and enhanced a pro-inflammatory response, further highlighting the different effects exerted on host cells by S. aureus strains with epidemiologically divergent behaviors.

A cross-sectional study was conducted to estimate the prevalence of intramammary infection (IMI) associated bacteria and to identify risk factors for pathogen group-specific IMI in water buffalo in Bangladesh. A California Mastitis Test (CMT) and bacteriological cultures were performed on 1,374 quarter milk samples collected from 763 water buffalo from 244 buffalo farms in nine districts in Bangladesh. Quarter, buffalo, and farm-related data were obtained through questionnaires and visual observations. A total of 618 quarter samples were found to be culture positive. Non-aureus staphylococci were the predominant IMI-associated bacterial species, and Staphylococcus (S.) chromogenes, S. hyicus, and S. epidermidis were the most common bacteria found. The proportion of non-aureus staphylococci or Mammaliicoccus sciuri (NASM), S. aureus, and other bacterial species identified in the buffalo quarter samples varied between buffalo farms. Therefore, different management practices, buffalo breeding factors, and nutrition were considered and further analyzed when estimating the IMI odds ratio (OR). The odds of IMI by any pathogen (OR: 1.8) or by NASM (OR: 2.2) was high in buffalo herds with poor milking hygiene. Poor cleanliness of the hind quarters had a high odds of IMI caused by any pathogen (OR: 2.0) or NASM (OR: 1.9). Twice daily milking (OR: 3.1) and farms with buffalo purchased from another herd (OR: 2.0) were associated with IMI by any pathogen. Asymmetrical udders were associated with IMI-caused by any bacteria (OR: 1.7). A poor body condition score showed higher odds of IMI by any pathogen (OR: 1.4) or by NASM (OR: 1.7). This study shows that the prevalence of IMI in water buffalo was high and varied between farms. In accordance with the literature, our data highlight that IMI can be partly controlled through better farm management, primarily by improving hygiene, milking management, breeding, and nutrition.

The goal of this study was to determine the plasma concentrations of the acute phase proteins fibrino-gen and ceruloplasmin during the pregnancy and postpartum period in goats. The experiment was carried out with six clinically healthy Bulgarian native goats, aged 46 years, weighing 4956 kg, reared at the Biobase of the Faculty of Veterinary Medicine – Stara Zagora. Blood samples for assay of plasma concentrations of the studied acute-phase proteins during pregnancy were collected over 7-day intervals, from the 14th to the 147th day of pregnancy. During the postpartum period, samples were obtained at 3-day intervals between the 1st and 15th postpartum day, as well as once on the 20th and 30th day after the parturition. The results indicated that throughout the first trimester of the preg-nancy, the highest average plasma fibrinogen values were established on the 14th day, while signifi-cantly lower values (P

Abstract A growing body of evidence shows that microRNA (miRNA), play important roles in regulating adipose tissue (AT) physiology and function. The objective was to characterize the AT miRNA profile in over-conditioned (HBCS, n = 19) versus moderate-conditioned (MBCS, n = 19) periparturient dairy cows. Tail-head subcutaneous AT biopsied on d -49 and 21 relative to parturition were used for miRNA sequencing. The miR-486 was the most significant miRNA among the upregulated miRNA on d -49, which might be related to more pronounced changes in lipogenesis and altered insulin sensitivity in AT of HBCS cows at dry-off. Comparing HBCS to MBCS on d 21, 23 miRNA were downregulated and 20 were upregulated. The predicted targets of upregulated differentially expressed (DE)-miRNA on d 21 were enriched in different pathways, including pathways related to lysosomes and peroxisomes. The predicted targets of downregulated DE-miRNA on d 21 were enriched in various pathways, including epidermal growth factor receptor, insulin resistance, hypoxia-inducible factor 1 signaling pathway, and autophagy. The results showed that over-conditioning was associated with changes in SCAT miRNA profile mainly on d 21, of which most were downregulated. The enriched pathways may participate in over-conditioning-associated metabolic challenges during early lactation.

Abstract This study aimed to determine the lipidome of water buffalo milk with intramammary infection (IMI) by non-aureus staphylococci (NAS), also defined as coagulase-negative staphylococci, using an untargeted lipidomic approach. Non-aureus Staphylococci are the most frequently isolated pathogens from dairy water buffalo milk during mastitis. A total of 17 milk samples from quarters affected by NAS-IMI were collected, and the lipidome was determined by liquid chromatography-quadrupole time-of-flight mass spectrometry. The results were compared with the lipidome determined on samples collected from 16 healthy quarters. The study identified 1934 different lipids, which were classified into 15 classes. The abundance of 72 lipids changed in NAS-IMI milk compared to healthy quarters. Significant changes occurred primarily in the class of free fatty acids. The results of this study provided first-time insight into the lipidome of dairy water buffalo milk. Moreover, the present findings provide evidence that NAS-IMI induces changes in water buffalo milk's lipidome.

The present study aims to evaluate the changes in concentrations of some acute phase proteins during Haemonchus contortus infection in lambs. This experiment was performed using 12 three-month-old healthy lambs, randomly allocated into 2 equal groups: G1 (uninfected control animals) and G2 (lambs infected with H. contortus). Each lamb of G2 group was orally inoculated with 4000 infective third stage larvae (L3) of H. contortus by placing a probe. Blood samples were collected on post infection days zero, 4, 7, 11, 14, 21, 28 and 32. After sampling, the blood was centrifuged, and the separated plasma was used for the quantitative determination of haptoglobin (Hp) and fibrinogen (Fb). The most pronounced changes occurred in Hp levels, which increased and attained the highest values on post infection days 4, 7, and 11. A peak concentration occurred on post infection day 7 when Hp increased by 45.96% vs the initial level, and by 44.08% vs the control level on the same day. There were no significant changes in Fb concentrations throughout the study.

Abstract Mastitis by non-aureus staphylococci (NAS) is a significant issue in dairy buffalo farming. In a herd with subclinical NAS mastitis, we identified Staphylococcus microti as the predominant species. To assess milk protein integrity and investigate potential disease markers, we characterized 12 NAS-positive and 12 healthy quarter milk samples by shotgun peptidomics combining peptide enrichment and high-performance liquid chromatography/tandem mass spectrometry (LC–MS/MS). We observed significant changes in the milk peptidome. Out of 789 total peptides identified in each group, 49 and 44 were unique or increased in NAS-positive and healthy milk, respectively. In NAS-positive milk, the differential peptides belonged mainly to caseins, followed by milk fat globule membrane proteins (MFGMP) and by the immune defense/antimicrobial proteins osteopontin, lactoperoxidase, and serum amyloid A. In healthy milk, these belonged mainly to MFGMP, followed by caseins. In terms of abundance, peptides from MFGMP and immune defense protein were higher in NAS-positive milk, while peptides from caseins were higher in healthy milk. These findings highlight the impact of NAS on buffalo milk quality and mammary gland health, even when clinical signs are not evident, and underscore the need for clarifying the epidemiology and relevance of the different NAS species in this dairy ruminant.

Physical activity in the form of “active breaks” can be combined with academic instruction in primary school. However, few studies have examined the feasibility of conducting active breaks in secondary school. To address this gap, we conducted focus groups (FGs) regarding the implementation of an active breaks (ABs) protocol with 20 teachers and 10 secondary school students. Barriers/facilitators toward the implementation of ABs were classified using grounded theory inductive methods framed by the socio-ecological model. Individual-level factors were instrumental for both teachers and students. Teachers highlighted personal fears and concerns regarding using ABs, while students reported fears related to peer behaviour during the activity. Both teachers and students agreed that ABs can improve cognitive skills and time-on-task behaviour. Teachers articulated concerns related to student behaviour during ABs including possible social exclusion and injury. Students felt that ABs might affect classroom management and interfere with maintaining students’ academic focus. Teachers underscored that ABs required social support from the administration and colleagues. Students felt that ABs could support teachers’ instructional focus and provide them with an energy respite. Collectively, the FGs suggested that environmental limitations could hinder the implementation of ABs. Involving teacher and student feedback during the codesign phase can rationally inform the design of school-based ABs.

Abstract Essential fatty acids (EFA) and conjugated linoleic acids (CLA) are unsaturated fatty acids with immune-modulatory effects, yet their synergistic effect is poorly understood in dairy cows. This study aimed at identifying differentially abundant proteins (DAP) and their associated pathways in dairy cows supplied with a combination of EFA and CLA during the transition from antepartum (AP) to early postpartum (PP). Sixteen Holstein cows were abomasally infused with coconut oil as a control (CTRL) or a mixture of EFA (linseed + safflower oil) and CLA (Lutalin, BASF) (EFA + CLA) from − 63 to + 63 days relative to parturition. Label-free quantitative proteomics was performed on plasma samples collected at days − 21, + 1, + 28, and + 63. During the transition time, DAP, consisting of a cluster of apolipoproteins (APO), including APOE, APOH, and APOB, along with a cluster of immune-related proteins, were related to complement and coagulation cascades, inflammatory response, and cholesterol metabolism. In response to EFA + CLA, specific APO comprising APOC3, APOA1, APOA4, and APOC4 were increased in a time-dependent manner; they were linked to triglyceride-enriched lipoprotein metabolisms and immune function. Altogether, these results provide new insights into metabolic and immune adaptation and crosstalk between them in transition dairy cows divergent in EFA + CLA status.

The present study aimed to evaluate the changes in concentrations of some biochemical parameters, as well as macro and microscopic alterations during Eimeria stiedae infection in rabbits. The experiment was performed using 12 threemonth- old healthy rabbits, randomly allocated into 2 equal groups: G1 (controls, uninfected animals) and G2 (rabbits infected with E. stiedae). Blood samples were collected at time zero (prior to the infection), 6th, 24th, and 48th hours, and also 7th, 14th, 21st, 28th days after the infection. After sampling, the blood was centrifuged, plasma was separated and frozen at -20 ºC until analyzed. Thawed plasma was used for the quantitative determination of haptoglobin (Hp), total protein (TP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), total cholesterol (TC), total bilirubin (TBIL), urea, and creatinine (CREA). The results in infected rabbits revealed a significant increase in Hp, AST, ALT, GGT, TBIL, and TC levels, as well as a significant decrease in ALP and urea. A weak hyperproteinemia was also observed. There were no changes in CREA concentration. At the end of the clinical investigation, all rabbits were humanely euthanized and necropsied. The post-mortem examination of the infected group revealed hepatomegaly, multifocal yellowish nodules diffusely spread over the liver surface and in the parenchyma, considerably dilated bile ducts, and biliary hyperplasia. Given the results obtained from this experiment, it can be affirmed that hepatic eimeriosis in rabbits is a severe parasitic disease leading to significant disturbances of liver histology and resulting changes in the biochemical profile of infected rabbits.

The need for movement, which characterizes the current generations of children, has become urgent and worrying. Despite the continuous projects carried out in primary school, few seems to improve health and motivation to adopt active lifestyles. Among the many projects carried out in recent years, active breaks seem to be gaining ground for their easiness of realization and sustainability over time. The active breaks proved to be very effective towards well being and cognitive activation representing an additional dose of physical activity that can help children in meeting the recommended levels of daily physical activity. Moreover, the active breaks represent an innovative strategy to improve the classroom climate and facilitate the educational action of teachers. Teachers, involved in the I-MOVE and ABS studies, of an inter-university study group (University of Bologna and University of Roma Tre), responded with great enthusiasm to the practice of active breaks. Teachers highlighted that active break produced a positive effect toward school routine, learning environment and activation of cognitive functions in children. The present paper reports data related to the awareness of teachers, with regard to the application of active breaks in their school day, in terms of feasibility, management and organization in the face of effects considered absolutely positive for the daily school experience.

After years of work, interrupted by plateaus of political pondering, the 2002 Budget Law (Art. 103) has finally officialized the inclusion of specialist teachers for the subject of Physical Education. That is, after the Italian Senate Bill S 992/2020, which mandated the introduction of specialist teachers to guarantee «a real and qualified teaching for children through interventions that are adequate and targeted in terms of motor development, but also to impact learning, prevention, and socialization» (D’Elia, 2022, p. 82).

The Montessorian proposal for childhood education appears highly modern and relevant in relation to the development of both motor skills and cognitive functions (Shivji, 2016;), strongly supported by neurosciences’ embodied theories (Roessingh, H. & Bence, M. 2018)), and the increasing wellbeing problem related to childhood (Pate et al, 2014; Ross, 2012). This review analyses Maria Montessori’s modern educational vision, in light of the emerging needs of today’s children. The contribution reviews existing literature focusing on body and movement, but connected with cognitive, emotional and well-being aspects, which are critical in preschool education, both for educators/teachers (Atli, 2016; Akkerman, 2014; Lillard, 2011), and for school reform policies (Lillard, 2019).

Small extracellular vesicles (sEV) are a class of extracellular vesicles (30–150 nm), delivering molecules including proteins, metabolites, and microRNAs (miRNAs), involved in physiological intercellular crosstalk and disease pathogenesis. The present pilot study aims are (I) to develop an easy and fast protocol for the isolation of sEV from plasma of mast cell tumor (MCT)-affected dogs; (II) to evaluate if miR-21-5p (sEV-miR-21-5p), a miRNA overexpressed by MCT, is associated with sEV. Seventeen dogs have been enrolled in the study: 4 healthy and 13 (6 with and 7 without nodal metastasis) MCT-affected dogs. sEV were isolated using size exclusion chromatography (SEC) (IZON column 35nm) and were characterized by Western blot, Nanoparticle tracking analysis, and transmission electron microscopy. sEV-miR-21-5p was quantified using digital PCR. sEV expressed the specific markers CD9 and TSG101, and a marker of mast cell tryptase. The sEV mean concentration and size were 2.68E + 10 particles/ml, and 99.6 nm, 2.89E + 10 particles/ml and 101.7 nm, and 3.21E + 10 particles/ml and 124 nm in non-metastatic, nodal metastatic, and healthy samples, respectively. The comparative analysis demonstrated that the level of sEV-miR-21-5p was significantly higher in dogs with nodal metastasis compared to healthy (P = 0.038) and without nodal metastasis samples (P = 0.007). In conclusion, the present work demonstrated that a pure population of sEV can be isolated from the plasma of MCT-affected dogs using the SEC approach and that the level of sEV-miR-21-5p is higher in nodal metastatic MCT-affected dogs compared with healthy and MCT-affected dogs without nodal involvement.

In the current study, we investigated dairy cows’ circulating microRNA (miRNA) expression signature during several key time points around calving, to get insights into different aspects of metabolic adaptation. In a trial with 32 dairy cows, plasma samples were collected on days −21, 1, 28, and 63 relative to calving. Individually extracted total RNA was subjected to RNA sequencing using NovaSeq 6,000 (Illumina, CA) on the respective platform of IGA Technology Services, Udine, Italy. MiRDeep2 was used to identify known and novel miRNA according to the miRbase collection. Differentially expressed miRNA (DEM) were assessed at a threshold of fold-change > 1.5 and false discovery rate < 0.05 using the edgeR package. The MiRWalk database was used to predict DEM targets and their associated KEGG pathways. Among a total of 1,692 identified miRNA, 445 known miRNA were included for statistical analysis, of which 84, 59, and 61 DEM were found between days −21 to 1, 1 to 28, and 28 to 63, respectively. These miRNA were annotated to KEGG pathways targeting the insulin, MAPK, Ras, Wnt, Hippo, sphingolipid, T cell receptor, and mTOR signaling pathways. MiRNA-mRNA network analysis identified miRNA as master regulators of the biological process including miR-138, miR-149-5p, miR-2466-3p, miR-214, miR-504, and miR-6523a. This study provided new insights into the miRNA signatures of transition to the lactation period. Calving emerged as a critical time point when miRNA were most affected, while the following period appeared to be recovering from massive parturition changes. The primarily affected pathways were key signaling pathways related to establishing metabolic and immune adaptations.

The aim of this study was to describe the goals, activities, and methods of EUMOVE project in developing a set of resources targeting both primary and secondary schools that allow the entire educational community to promote healthy lifestyles (HL). The EUMOVE project is an Erasmus+ program based in the Creating Active Schools (CAS) framework. The project lasted 3 years and was developed by 14 academic and non-governmental institutions from Spain, Portugal, France, Italy, and the UK. EUMOVE was divided into three phases. In the first phase, several work packages were carried out aimed to ensure the coordination/management of the project activities. In the second phase, seven educational resources strengthened by rigorous scientific research were developed to promote HL from schools. During the last phase, all the resources were disseminated through scientific seminars, workshops with families and teachers, and the online promotion by the non-governmental institutions of each country. The EUMOVE project developed and promoted a smartphone APP, video/activity repository of physically active lessons, active break virtual platform, learning units, and parent/teachers/school-leaders' guidelines to promote physical activity, active commuting, active school playgrounds, healthy diet, and sleep habits. To our knowledge, EUMOVE is the first European project to provide a set of practical tools based on scientific evidence to help schools or future school-wide interventions implement a paradigm shift based on the CAS framework for the promotion of HL. Future research will need to investigate the implementation, effectiveness, and scalability of this proposal. [ABSTRACT FROM AUTHOR]
