There are several challenges in conducting the CBPAR, such as the effort and time spent on building partnerships, co-learning and mutual understanding, and the power equilibrium involved. Despite this, the success of the CBPAR process provided opportunities for community mobilization, empowerment and sustainability of the intervention. Evaluation of the process and outcomes of the intervention provided community health researchers and practitioners with evidence of the theory-guided community participatory approach. The purpose of this study was to examine the final analytic sample of a longitudinal randomized control trial (RCT) evaluation of a sexual violence prevention program at a university after facing challenges with the implementation of a self-generated identification code. The matched and unmatched samples (e.g., all unique surveys across all time periods) included 10,135 surveys. INCB39110 Eighty-eight percent of these surveys were matched into the final longitudinal dataset. Findings suggest that students with certain characteristics were more likely to be matched over time (i.e., students who participated in student government, Latino/a students, and Asian students). In addition, students who did not comply with RCT protocol were less likely to be matched. Student history of victimization or perpetration of sexual violence was not associated with being matched over time. This study provides recommendations for preventing matching problems in longitudinal studies, a process for rectifying matching issues and a critique of studies that do not address issues of matching-related sample bias in their final analytic sample. Campylobacter spp. are the leading causes of bacterial human gastroenteritis worldwide; being poultry farms the main source of infections. In order to obtain information on prevalence and diversity of Campylobacter-infected flocks in the North of Spain, fourteen farms were studied between autumn and spring in 2014 and 2015, respectively. Moreover, virulence genes involved in pathogenicity and antimicrobial resistance were investigated. A survey about preventive hygiene practices at farms was performed to determine the risky practices that could contribute to the presence of Campylobacter in this step of the poultry food chain. Testing the presence of Campylobacter spp. showed 43 % of the farms were positive during autumn, whereas only 31 % were positive in spring. A very high prevalence within-flock was observed (43.1 % to 88.6 %) and C. jejuni was the most prevalent species in both periods. Genotyping by pulsed field gel electrophoresis (PFGE) showed a high heterogeneity among farms (309 isolates clustered into 21 pulsotypes). Virulence genes were present in all C. jejuni isolates while cdtA and cdtC were absent in C. coli. On the contrary, the latter showed higher antimicrobial resistance than C. jejuni. This study suggests that environment might be one of the main sources for Campylobacter transmission, as water supply seemed to be a clear cause of the contamination in a specific farm. However, in other farms other environmental factors contributed to the contamination, confirming the multifactorial origin of Campylobacter colonization in broilers. Therefore, biosecurity measures in farms are crucial to reduce Campylobacter contamination, which may have important implications for human and animal health. BACKGROUND Tylosin is a commonly used in-feed antimicrobial and is approved in several countries to reduce the incidence of liver abscesses in beef cattle. Macrolides are critically important antimicrobials in human health and used to treat some foodborne bacterial diseases, such as Campylobacter jejuni and Salmonella. Feeding tylosin could select for resistant enteric bacteria in cattle, which could contaminate beef products at slaughter and potentially cause foodborne illness. link2 We conducted a systematic review and meta-analysis to evaluate the impact of feeding tylosin to cattle on phenotypic and genotypic resistance in several potential zoonotic enteric bacteria Enterococcus species, Escherichia coli, Salmonella enterica subspecies enterica, and Campylobacter species. link3 This review was registered with PROSPERO (#CRD42018085949). RESULTS Eleven databases were searched for primary research studies that fed tylosin at approved doses to feedlot cattle and tested bacteria of interest for phenotypic or genotypic redministration or the time since the last dose. CONCLUSIONS When fed at approved dosages for typical durations, tylosin increases the proportion of macrolide-resistant enterococci in the cattle gastrointestinal tract, which could pose a zoonotic risk to human beef consumers. Feeding tylosin for short durations may mitigate the impact on macrolide-resistant enterococci and further studies are encouraged to determine the effect of minimizing or eliminating tylosin use in beef cattle. There may also be an impact on other bacteria and other antimicrobial resistances but additional details or data are needed to strengthen these comparisons. We encourage authors of antimicrobial-resistance studies to follow reporting guidelines and publish details of all comparisons to strengthen future meta-analyses. A serosurvey was performed to assess exposure to Toxoplasma gondii in zoo animals in Spain and to determine the dynamics of seropositivity in some zoo species over time. Sera from 393 zoo animals belonging to 91 species were collected in eight zoos in Spain between 2007 and 2019. Additionally, 39 of the 393 animals from five of the analyzed zoos were longitudinally sampled during the same study period. Antibodies to T. gondii were detected in 165 (42.0 %; CI95 % 37.1-46.9) of 393 animals by the modified agglutination test (MAT, cut-off = 25). Antibody titers of 25, 50, 100 and ≥500 were found in 25 (15.2 %), 65 (39.4 %), 26 (15.8 %), and 49 (29.7 %) of the seropositive animals, respectively. Feeding habits (carnivorous species) was a risk factor (OR = 5.6; P less then 0.001; CI95 % 3.8-9.0) potentially associated with T. gondii exposure. Eighteen (46.2 %) of the 39 animals longitudinally sampled were always seropositive and five animals (12.8 %) (two spotted hyaena [Crocuta crocuta], one blesbok [Damaliscus pygargus], one white rhinoceros [Ceratotherium simum] and one mouflon [Ovis aries musimon]) seroconverted during the study period. Our results evince a wide circulation of T. gondii in zoos in Spain, including wild felids. Zoo animals can be useful sentinel species to monitor T. gondii circulation in epidemiological scenarios with a close human-wildlife interface. Control measures should be implemented in zoo parks to minimize the risk of exposure of zoo species to T. gondii. To meet the demands of the beef cattle sector in France, weaned beef calves are transported to sorting facilities and sorted into batches composed of animals of similar body weight (BW) before the beginning of the fattening period. This procedure aims to facilitate animal management. However, it leads to practices that affect animal welfare, health and performance, such as transporting weaned beef calves over long distances and mixing animals originating from different cow/calf farms. In contrast, other potentially beneficial practices, such as pre-weaning vaccination against bovine respiratory diseases (BRD), are seldom taken into consideration when batches are formed. This observational study, based on field data from 15,735 Charolais bulls, aimed to investigate which criteria should be favored for batch constitution by quantifying the effect of batch characteristics on the growth performance of young bulls during the fattening period. Clustering analysis was used to group young bulls exhibiting similar batlls could be obtained by minimizing transportation distance, providing vaccination programs against BRD before weaning, and maintaining groups from the same cow/calf farm instead of constituting groups of animals with similar BW at the beginning of fattening. Activity-based protein profiling (ABPP) has become an emerging chemical proteomic approach to illustrate the interaction mechanisms between compounds and proteins. This approach has combined organic synthesis, biochemistry, cell biology, biophysics and bioinformatics to accelerate the process of drug discovery in target identification and validation, as well as in the stage of lead discovery and optimization. This review will summarize new developments and applications of ABPP in medicinal chemistry. Here, we mainly described the design principles of activity-base probes (ABPs) and general workflows of ABPP approach. Moreover, we discussed various basic and advanced ABPP strategies and their applications in medicinal chemistry, including competitive and comparative ABPP, two-step ABPP, fluorescence polarization ABPP (FluoPol-ABPP) and ABPs for visualization. In conclusion, this review will give a general overview of the applications of ABPP as a powerful and efficient technique in medicinal chemistry. Since our study showed that sulfone derivatives' action mode creates a lesser risk of inducing widespread resistance among Candida spp., we continued verifying sulfones' antifungal activity using the following newly synthesized derivatives bromodichloromethy-4-hydrazinyl-3-nitrophenyl sulfone (S1), difluoroiodomethyl-4-hydrazinyl-3-nitrophenyl sulfone (S2), and chlorodifluoromethyl-4-hydrazinyl-3-nitrophenyl sulfone (S3). As the mechanism by which sulfones gain access to the cytoplasm has not been elucidated yet, in order to track S1-3, we coupled their hydrazine group with BODIPY (final S1-3 BODIPY-labelled were named SB1-3). This approach allowed us to follow the vital internalization and endocytic routing of SB1-3, while BODIPY interacts primarily with fungal surfaces, thus confirming that S1-3 and their counterparts SB1-2 behaved as non-typical agents by damaging the cell membrane and wall after being endocytosed (SB1-3 fluorescence visible inside the unlysed sessile cells). Thus greatly decreasing the liin combination with antifungal agents of reference to treat C. albicans infections. BACKGROUND Sensitivity is defined as parents ability to perceive, react and respond to children signals. Having a history of childhood maltreatment changes the way adults perceive visual emotions. These perceptual characteristics could have important consequences on how these parents respond to their children. OBJECTIVE The current study examines how a history of childhood maltreatment moderates the relationship between maternal emotion recognition in child faces and sensitive behaviors toward their child during free-play and a structured task. PARTICIPANTS AND SETTING Participants included 58 mothers and their children aged between 2 and 5 years. METHODS Mothers were exposed to a set of photographs of child faces showing morphed images of the six basic emotional expressions. Mother-child interactions were then coded for sensitive behaviors. Mothers' history of childhood maltreatment was assessed using the Childhood Trauma Questionnaire. RESULTS Maltreatment severity was related to poorer abilities in emotion recognition. However, the association between emotion recognition and sensitive behavior was moderate by history of childhood maltreatment. For mothers exposed to a severe form of childhood maltreatment, a better emotion recognition was related to less sensitive behaviors toward the child, both during free-play and the structured task. CONCLUSION This relationship is unique to these mothers and is inconsistent with Ainsworth's definition of sensitivity. These results have important implications as they suggest mothers with a history of severe maltreatment would need tailored interventions which take into account their particular reactions to children's emotions.
