RESUMO

Schools are a critical setting to promote healthy youth development through the provision of evidence-based programs (EBPs), yet preventive EBPs in schools are underutilized. The Exploration, Preparation, Implementation, Sustainment (EPIS) framework highlights numerous factors that may influence program adoption during the Exploration phase and progress monitoring during the Implementation phase. However, no research has systematically and simultaneously identified the factors that influence school administrators' decision-making during these important processes. We conducted semi-structured interviews with 24 school administrators in the Midwestern region of the U.S. to understand how they weigh various considerations that inform their adoption and progress monitoring of prevention programs. Results indicated that school administrators consider five separate factors during the adoption decision, prioritized in the following order: need for the program, school community buy-in, contextual fit, resources, and program characteristics (including the evidence-base). Further, administrators consider five indicators to monitor program performance, prioritized as follows: intervention fidelity, quantitative and qualitative data that determine if the identified need was met, school community buy-in, resource consumption, and program characteristics. Implications for prevention scientists and suggestions for future research are discussed.

RESUMO

Interprofessional Education (IPE) as a preparatory stage for Interprofessional collaboration (IPC) is overlooked in some low-and middle-income countries, including Indonesia. One of the driving forces behind IPC is the development of Interprofessional Identity (IPI), which has yet to be assessed in the Indonesian context. Our study aims were translating and culturally adapting the Extended Professional Identity Scale (EPIS) and confirming its construct validity. We invited third-year students from three programs (medicine, nursing, and dietetics) without previous IPE experience to participate in the study. Using Confirmatory Factor Analysis (CFA), we examined the construct validity, analyzed internal consistency, and conducted a Kruskal-Wallis test to identify variations across professions. Of 513 students approached, 335 participated (response rate 65.3%). The CFA showed factor loadings ranging between .59 and .86, while correlations among subscales varied from .55 to .86. All five goodness-of-fit indices were sufficient. The internal consistency of subscales interprofessional belonging, commitment, and beliefs was .82, .84 and .87, respectively, and .90 for the overall scale. Interprofessional belonging and commitment were different among various students (p-value = .009 and .004) and the dietetics students had lower scores than other students. The Indonesian EPIS (EPIS-RI) demonstrated reliability and construct validity.

RESUMO

Bacterial resistance to antibiotics has been long recognized as a priority to address for human health. Among all micro-organisms, the so-called multi-drug resistant (MDR) bacteria, which are resistant to most, if not all drugs in our current arsenal, are particularly worrisome. The World Health Organization has prioritized the ESKAPE (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species) pathogens, which include four Gram-negative bacterial species. In these bacteria, active extrusion of antimicrobial compounds out of the cell by means of 'molecular guns' known as efflux pumps is a main determinant of MDR phenotypes. The resistance-nodulation-cell division (RND) superfamily of efflux pumps connecting the inner and outer membrane in Gram-negative bacteria is crucial to the onset of MDR and virulence, as well as biofilm formation. Thus, understanding the molecular basis of the interaction of antibiotics and inhibitors with these pumps is key to the design of more effective therapeutics. With the aim to contribute to this challenge, and complement and inspire experimental research, in silico studies on RND efflux pumps have flourished in recent decades. Here, we review a selection of such investigations addressing the main determinants behind the polyspecificity of these pumps, the mechanisms of substrate recognition, transport and inhibition, as well as the relevance of their assembly for proper functioning, and the role of protein-lipid interactions. The journey will end with a perspective on the role of computer simulations in addressing the challenges posed by these beautifully complex machineries and in supporting the fight against the spread of MDR bacteria.

RESUMO

BACKGROUND: Working as a neonatologist in a neonatal intensive care unit (NICU) is stressful and involves ethically challenging situations. These situations may cause neonatologists to experience high levels of moral distress, especially in the context of caring for extremely premature infants (EPIs). In Greece, moral distress among neonatologists working in NICUs remains understudied and warrants further exploration. METHODS: This prospective qualitative study was conducted from March to August 2022. A combination of purposive and snowball sampling was used and data were collected by semi-structured interviews with twenty neonatologists. Data were classified and analyzed by thematic analysis approach. RESULTS: A variety of distinct themes and subthemes emerged from the analysis of the interview data. Neonatologists face moral uncertainty. Furthermore, they prioritize their traditional (Hippocratic) role as healers. Importantly, neonatologists seek third-party support for their decisions to reduce their decision uncertainty. In addition, based on the analysis of the interview data, multiple predisposing factors that foster and facilitate neonatologists' moral distress emerged, as did multiple predisposing factors that are sometimes associated with neonatologists' constraint distress and sometimes associated with their uncertainty distress. The predisposing factors that foster and facilitate neonatologists' moral distress thus identified include the lack of previous experience on the part of neonatologists, the lack of clear and adequate clinical practice guidelines/recommendations/protocols, the scarcity of health care resources, the fact that in the context of neonatology, the infant's best interest and quality of life are difficult to identify, and the need to make decisions in a short time frame. NICU directors, neonatologists' colleagues working in the same NICU and parental wishes and attitudes were identified as predisposing factors that are sometimes associated with neonatologists' constraint distress and sometimes associated with their uncertainty distress. Ultimately, neonatologists become more resistant to moral distress over time. CONCLUSIONS: We concluded that neonatologists' moral distress should be conceptualized in the broad sense of the term and is closely associated with multiple predisposing factors. Such distress is greatly affected by interpersonal relationships. A variety of distinct themes and subthemes were identified, which, for the most part, were consistent with the findings of previous research. However, we identified some nuances that are of practical importance. The results of this study may serve as a starting point for future research.

RESUMO

BACKGROUND: Norwegian school health services received a national best-practice guideline in 2017. To promote healthy life skills and identify adolescents needing support, the guideline includes strong recommendations for individual consultations with all 8th graders and increased collaboration with schools. To help implement the recommendations, a blended implementation strategy (SchoolHealth) was co-created with school nurses, students, and stakeholders. SchoolHealth consists of three implementation elements: Digital dialog and administration tool (audit and feedback +), Dialog support (external consultation), and Collaboration materials (targeted dissemination). This hybrid study will test the main and combined effects of the elements on guideline fidelity and effectiveness. METHODS: The GuideMe study is a factorial cluster randomized controlled trial examining SchoolHealth's effectiveness on guideline fidelity and guideline effectiveness goals. Forty Norwegian secondary schools will be randomized to eight different combinations of the elements in SchoolHealth. Participants will include school nurses and school personnel from these schools, and 8th grade students (n = 1200). Primary outcomes are school nurses' fidelity to the guidelines and student's ability to cope with their life (i.e., health literacy, positive health behaviors and self-efficacy). Quantitative methods will be used to test effects and mechanisms, while mixed- and qualitative methods will be used to explore mechanisms, experiences, and other phenomena in depth. Participants will complete digital questionnaires at the start and end of the schoolyear, and after the consultation during the schoolyear. The study will run in two waves, each lasting for one school year. The multifactorial design allows testing of interactions and main effects due to equal distribution of all factors within each main effect. Sustainment and scale-up of optimized SchoolHealth elements using national infrastructure are simultaneously prepared. DISCUSSION: The study will investigate possible effects of the implementation elements in isolation and in combination, and hypothesized implementation mechanisms. In-depth study of user experiences will inform improvements to elements in SchoolHealth. The results will yield causal knowledge about implementation strategies and the mechanisms through which they assert effects. Mixed-methods will provide insights into how and when the elements work. Optimizing guideline implementation elements can support adolescents in a crucial life phase. TRAIL REGISTRATION: ISRCTN24173836. Registration date 8 August 2022.

RESUMO

Our school-based asthma program has reduced asthma exacerbations for youth with health disparities in the Denver metropolitan area, due partly to addressing social determinants of health, such as access to health care and medications. Dissemination and implementation (D&I) science approaches accelerate the translation of evidence-based programs into routine practice. D&I methods are being applied more commonly to improve health equity. The purpose of this publication was to give an overview of D&I research methods, using our school-based asthma program as an example. To successfully scale out our program across the state of Colorado, we are applying a D&I framework that guides the adaptation of our existing implementation approach to better meet our stakeholders' local context-the Exploration, Preparation, Implementation, Sustainment framework. In a pragmatic trial design, we will evaluate the outcomes of implementing the program across 5 Colorado regions, with attention to health equity, using a second commonly used D&I framework-Reach, Effectiveness, Adoption, Implementation, and Maintenance. Our central hypothesis is that our program will have broad and equitable reach to eligible students (primary outcome) and will reduce asthma attacks and symptoms. This D&I approach accelerates dissemination of our program and is an applicable process for translating other effective allergy/asthma programs to address asthma and allergy-related disparities.

RESUMO

The primary aim is to assess the implementation of an eight-session, group therapy pilot for Black and Latina transgender women in Chicago in terms of implementation outcomes regarding intervention effectiveness, acceptability, appropriateness, and feasibility. The Exploration Preparation Implementation Sustainment (EPIS) framework guided implementation processes, including community engagement as an implementation strategy, and an implementation taxonomy was used to evaluate outcomes of acceptability, appropriateness, and feasibility, in addition to intervention effectiveness regarding anxiety and community connectedness. Two rounds of the pilot were completed in 2020, during the COVID-19 pandemic, at a community-based organization serving LGBTQ+ (lesbian, gay, bisexual, transgender, queer/questioning) youth on Chicago's West Side. Participants (N = 14) completed a baseline and postintervention assessment and evaluations after each of eight intervention modules. Descriptive statistics show improvement across measures of anxiety and community connectedness, and high mean scores across domains of acceptability, appropriateness, and feasibility. Pilot findings indicate intervention effectiveness, acceptability, appropriateness, and feasibility to address mental health and social support of Black and Latina transgender women. Additional resources are needed for transgender community-engaged mental health programs and research to establish core and adaptable intervention elements, scaled-up evidence for clinical effectiveness, and, most importantly, to improve mental health outcomes and the sustainability of such interventions.

RESUMO

Despite advances in evidence-based practices (EBP) to support HIV prevention and treatment, youth ages 13-24 experience significant disparities in HIV risk and outcomes. An important factor in this disparity is poor EBP implementation, yet implementation research is limited, particularly in youth-serving settings. This study used the Exploration, Preparation, Implementation, Sustainment (EPIS) framework to guide the implementation of four Motivational Interviewing (MI) and MI-framed interventions into youth-serving HIV prevention and treatment settings. Key stakeholders (n = 153) across 13 sites completed pre-implementation interviews. Stakeholders' comments identified two critical factors for effective implementation: fit with the patient population and provider receptivity, including concerns about scope of practice, buy-in, and time. Stakeholders recommended strategies for structuring training, fidelity monitoring, and facilitating implementation including engaging informal leaders, collaboratively developing the implementation strategy, and site-wide implementation. Results highlight the importance of pre-implementation contextual assessment and strategic planning for identifying provider concerns and developing responsive implementation strategies.


RESUMEN: A pesar de los avances en las prácticas basadas en evidencia (EBP, por sus siglas en inglés) para apoyar la prevención y el tratamiento del VIH, los jóvenes de 13 a 24 años atraviesan disparidades significativas en el riesgo y los desenlaces del VIH. Un factor importante en esta disparidad es la implementación deficiente de las EBP, aunque la investigación sobre la implementación es limitada, particularmente en entornos que atienden a jóvenes. Este estudio utilizó el marco de Exploración, Preparación, Implementación, Mantenimiento (EPIS) para guiar la implementación de cuatro entrevistas motivacionales (MI) e intervenciones enmarcadas en MI en entornos de prevención y tratamiento del VIH que atienden a jóvenes. Las partes interesadas clave (n = 153) en 13 sitios completaron las entrevistas previas a la implementación. Los comentarios de las partes interesadas identificaron dos factores críticos para una implementación efectiva: idoneidad para la población de pacientes y receptividad de los proveedores, incluidas las preocupaciones sobre el alcance de la práctica, la aceptación y el tiempo. Las partes interesadas recomendaron estrategias para estructurar la capacitación, monitorear la fidelidad, y facilitar la implementación, incluyendo la participación de líderes informales, el desarrollo colaborativo de la estrategia de implementación y la implementación en todo el sitio. Los resultados destacan la importancia de la evaluación contextual previa a la implementación y la planificación estratégica para identificar las preocupaciones de los proveedores y desarrollar estrategias de implementación que respondan a ellas.

RESUMO

Understanding possible barriers and facilitators to effective implementation of evidence-based interventions to help high-risk youth prevent and manage HIV is crucial for their scale-up. This manuscript analyzes qualitative interview data collected during the early phase implementation of a motivational interviewing (MI) based intervention at 10 HIV care clinics in the United States providing services to youth. Using the Exploration-Preparation-Implementation-Sustainment (EPIS) framework to understand the implementation and the dynamic adaptation process (DAP) model to balance notions of intervention fidelity and flexibility, providers and stakeholders at each site (N = 97) were interviewed prior to implementation to gather their perspectives on organizational readiness for the intervention, as well as provider and client characteristics. The interviewers summarized their experience with rapid feedback forms (RFFs). Data extracted from the RFFs highlighted anticipated barriers to and facilitators of the proposed MI-based intervention, with the EPIS framework used to organize these findings. Study findings illustrate the inner and outer contextual factors that affect implementation and denote the points at which the MI-based intervention may be tailored to fit the unique context of a clinic while remaining faithful to the intervention's original design.

RESUMO

BACKGROUND: Recent calls to action have been made for Implementation Science to attend to health inequities at the intersections of race, gender, and social injustice in the United States. Transgender people, particularly Black and Latina transgender women, experience a range of health inequities and social injustices. In this study, we compared two processes of transgender community engagement in Los Angeles and in Chicago as an implementation strategy to address inequitable access to care; we adapted and extended the Exploration Planning Implementation and Sustainment (EPIS) framework for transgender health equity. METHODS: A comparative case method and the EPIS framework were used to examine parallel implementation strategies of transgender community engagement to expand access to care. To foster conceptual development and adaptation of EPIS for trans health equity, the comparative case method required detailed description, exploration, and analyses of the community-engagement processes that led to different interventions to expand access. In both cities, the unit of analysis was a steering committee made up of local transgender and cisgender stakeholders. RESULTS: Both steering committees initiated their exploration processes with World Café-style, transgender community-engaged events in order to assess community needs and structural barriers to healthcare. The steering committees curated activities that amplified the voices of transgender community members among stakeholders, encouraging more effective and collaborative ways to advance transgender health equity. Based on analysis and findings from the Los Angeles town hall, the steering committee worked with a local medical school, extending the transgender medicine curriculum, and incorporating elements of transgender community-engagement. The Chicago steering committee determined from their findings that the most impactful intervention on structural racism and barriers to healthcare access would be to design and pilot an employment program for Black and Latina transgender women. CONCLUSION: In Los Angeles and Chicago, transgender community engagement guided implementation processes and led to critical insights regarding specific, local barriers to healthcare. The steering committee itself represented an important vehicle for individual-, organizational-, and community-level relationship and capacity building. This comparative case study highlights key adaptations of EPIS toward the formation of an implementation science framework for transgender health equity.

RESUMO

BACKGROUND: The uptake of HIV testing services among adolescents and young adults in Zimbabwe is low due to stigma associated with the risk of mental and social harm. The WHO recommends HIV self-testing (HIVST) as an innovative approach to improve access to HIV testing for this hard-to-reach populations. This study describes the development and implementation of a coordinated multifaceted and multidisciplinary campus-based approach to improve the uptake of HIV testing among university students in Zimbabwe. METHODS: We utilized both quantitative and qualitative methods guided by the Exploration, Preparation, Implementation, and Sustainment Framework. A formative survey, in-depth interviews, and a scoping review were conducted as part of the situation analysis. Implementers (peer educators and health workers) were trained and community dialogue sessions were conducted to ascertain the determinants (enablers and barriers) influencing both the inner and outer contexts. Self-test kits were disbursed over 6 months before a summative evaluation survey was conducted. Qualitative data were analyzed thematically while the chi-squared test was used to analyze quantitative data. RESULTS: The formative evaluation showed that 66% of students intended to test and 44% of the enrolled students collected HIVST test kits. Giving comprehensive and tailored information about the intervention was imperative to dispel the initial skepticism among students. Youth-friendly and language-specific packaging of program materials accommodated the students. Despite the high acceptability of the HIVST intervention, post-test services were poorly utilized due to the small and isolated nature of the university community. Implementers recommended that the students seek post-test services off-site to ensure that those with reactive results are linked to treatment and care. CONCLUSIONS: Peer-delivered HIVST using trained personnel was acceptable among adolescents and young adults offered the intervention at a campus setting. HIVST could increase the uptake of HIV testing for this population given the stigma associated with facility-based HTS and the need for routine HIV testing for this age group who may not otherwise test. An off-site post-test counseling option is likely to improve the implementation of a campus-based HIVST and close the linkage to treatment and care gap.

RESUMO

BACKGROUND: Most justice-involved youth are supervised in community settings, where assessment and linkage to substance use (SU) treatment services are inconsistent and fragmented. Only 1/3 of youth with an identified SU need receive a treatment referral and even fewer initiate services. Thus, improving identification and linkage to treatment requires coordination across juvenile justice (JJ) and behavioral health (BH) agencies. The current study examines the comparative effectiveness of two bundled implementation intervention strategies for improving SU treatment initiation, engagement, and continuing care among justice-involved youth supervised in community settings. Exploration, Preparation, Implementation, Sustainment (EPIS) served as the conceptual framework for study design and selection/timing of implementation intervention components, and the BH Services Cascade served as the conceptual and measurement framework for identifying and addressing gaps in service receipt. METHODS: Part of a larger Juvenile-Justice Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS) Cooperative, this study involved a multisite, cluster-randomized control trial where sites were paired then randomly assigned to receive Core (training teams on the BH Services Cascade and data-driven decision making; supporting goal selection) or Core+Enhanced (external facilitation of implementation teams) intervention components. Youth service records were collected from 20 JJ community supervision agencies (in five states) across five study phases (baseline, pre-randomization, early experiment, late experiment, maintenance). Implementation teams comprised of JJ and BH staff collaboratively identified goals along the BH Cascade and used data-driven decision-making to implement change. RESULTS: Results suggest that Core intervention components were effective at increasing service receipt over time relative to baseline, but differences between Core and Core+Enhanced conditions were non-significant. Time to service initiation was shorter among Core+Enhanced sites, and deeper Cascade penetration occurred when external facilitation (of implementation teams) was provided. Wide variation existed in the degree and nature of change across service systems. CONCLUSIONS: Findings demonstrate the criticality of early EPIS phases, demonstrating that strategies provided during the formative exploration and preparation phases produced some improvement in service receipt, whereas implementation-focused activities produced incremental improvement in moving youth farther along the Cascade.

RESUMO

Acinetobacter baumannii is an ESKAPE pathogen known to cause fatal nosocomial infections. With the surge of multidrug resistance (MDR) in the bacterial system, effective treatment measures have become very limited. The MDR in A. baumannii is contributed by various factors out of which efflux pumps have gained major attention due to their broad substrate specificity and wide distribution among bacterial species. The efflux pumps are involved in the MDR as well as contribute to other physiological processes in bacteria, therefore, it is critically important to inhibit efflux pumps in order to combat emerging resistance. The present review provides insight about the different efflux pump systems in A. baumannii and their role in multidrug resistance. A major focus has been put on the different strategies and alternate therapeutics to inhibit the efflux system. This includes use of different efflux pump inhibitors-natural, synthetic or combinatorial therapy. The use of phage therapy and nanoparticles for inhibiting efflux pumps have also been discussed here. Moreover, the present review provides the knowledge of barriers in development of efflux pump inhibitors (EPIs) and their approval for commercialization. Here, different prospectives have been discussed to improve the therapeutic development process and make it more compatible for clinical use.

RESUMO

Herein, 15 phenylpiperazine 3-benzyl-5,5-dimethylhydantoin derivatives (1-15) were screened for modulatory activity towards Msr(A) efflux pump present in S. epidermidis bacteria. Synthesis, crystallographic analysis, biological studies in vitro and structure-activity relationship (SAR) analysis were performed. The efflux pump inhibitory (EPI) potency was determined by employing ethidium bromide accumulation assay in both Msr(A) efflux pump overexpressed (K/14/1345) and deficient (ATCC 12228) S. epidermidis strains. The series of compounds was also evaluated for the capacity to reduce the resistance of K/14/1345 strain to erythromycin, a known substrate of Msr(A). The study identified five strong modulators for Msr(A) in S. epidermidis. The 2,4-dichlorobenzyl-hydantoin derivative 9 was found as the most potent EPI, inhibiting the efflux activity in K/14/1345 at a concentration as low as 15.63 µM. Crystallography-supported SAR analysis indicated structural properties that may be responsible for the activity found. This study identified the first synthetic compounds able to inhibit Msr(A) efflux pump transporter in S. epidermidis. Thus, the hydantoin-derived molecules found can be an attractive group in search for antibiotic adjuvants acting via Msr(A) transporter.

RESUMO

BACKGROUND: Integrated care is the coordination of general and behavioral health and is a highly promising and practical approach to improving healthcare delivery and patient outcomes. While there is growing interest and investment in integrated care implementation internationally, there are no formal guidelines for integrated care implementation applicable to diverse healthcare systems. Furthermore, there is a complex interplay of factors at multiple levels of influence that are necessary for successful implementation of integrated care in health systems. METHODS: Guided by the Exploration, Preparation, Implementation, Sustainment (EPIS) framework (Aarons et al., 2011), a multiple case study design was used to address two research objectives: 1) To highlight current integrated care implementation efforts through seven international case studies that target a range of healthcare systems, patient populations and implementation strategies and outcomes, and 2) To synthesize the shared and unique challenges and successes across studies using the EPIS framework. RESULTS: The seven reported case studies represent integrated care implementation efforts from five countries and continents (United States, United Kingdom, Vietnam, Israel, and Nigeria), target a range of clinical populations and care settings, and span all phases of the EPIS framework. Qualitative synthesis of these case studies illuminated common outer context, inner context, bridging and innovation factors that were key drivers of implementation. CONCLUSIONS: We propose an agenda that outlines priority goals and related strategies to advance integrated care implementation research. These goals relate to: 1) the role of funding at multiple levels of implementation, 2) meaningful collaboration with stakeholders across phases of implementation and 3) clear communication to stakeholders about integrated care implementation. TRIAL REGISTRATION: Not applicable.

RESUMO

If evidence-based interventions (EBIs) are not sustained, investments are wasted and public health impact is limited. Leadership has been suggested as a key determinant of implementation and sustainment; however, little empirical work has examined this factor. This mixed-methods study framed using the Exploration, Preparation, Implementation, Sustainment (EPIS) conceptual framework examines leadership in both the outer service system context and inner organizational context in eleven system-wide implementations of the same EBI across two U.S. states and 87 counties. Quantitative data at the outer context (i.e., system) and inner context (i.e., team) levels demonstrated that leadership predicted future sustainment and differentiated between sites with full, partial, or no sustainment. In the outer context positive sustainment leadership was characterized as establishing a project's mission and vision, early and continued planning for sustainment, realistic project plans, and having alternative strategies for project survival. Inner context frontline transformational leadership predicted sustainment while passive-avoidant leadership predicted non-sustainment. Qualitative results found that sustainment was associated with outer context leadership characterized by engagement in ongoing supportive EBI championing, marketing to stakeholders; persevering in these activities; taking action to institutionalize the EBI with funding, contracting, and system improvement plans; and fostering ongoing collaboration between stakeholders at state and county, and community stakeholder levels. For frontline leadership the most important activities included championing the EBI and providing practical support for service providers. There was both convergence and expansion that identified unique contributions of the quantitative and qualitative methods. Greater attention to leadership in both the outer system and inner organizational contexts is warranted to enhance EBI implementation and sustainment.

RESUMO

BACKGROUND: The bacterium Staphylococcus aureus has stood out for presenting a high adaptability, acquiring resistance to multiple drugs. The search for natural or synthetic compounds with antibacterial properties capable of reversing the resistance of S. aureus is the main challenge to be overcome today. Natural products such as chalcones are substances present in the secondary metabolism of plants, presenting important biological activities such as antitumor, antidiabetic, and antimicrobial activity. OBJECTIVES: In this context, the aim of this work was to synthesize the chalcone (2E)-1-(3'-aminophenyl)-3-(4-dimethylaminophenyl)-prop-2-en-1-one with nomenclature CMADMA, confirm its structure by nuclear magnetic resonance (NMR), and evaluate its antibacterial properties. METHODS: The synthesis methodology used was that of Claisen-Schmidt, and spectroscopic characterization was performed by NMR. For microbiological assays, the broth microdilution methodology was adopted in order to analyze the antibacterial potential of chalcones and to analyze their ability to act as a possible inhibitor of ß-lactamase and efflux pump resistance mechanisms, present in S. aureus strain K4100. RESULTS: The results obtained show that CMADMA does not show direct antibacterial activity, expressing a MIC of ≥1024 µg/mL, or on the enzymatic mechanism of ß-lactamase; however, when associated with ethidium bromide in efflux pump inhibition assays, CMADMA showed promising activity by reducing the MIC of the bromide from 64 to 32 µg/mL. CONCLUSION: We conclude that the chalcone synthesized in this study is a promising substance to combat bacterial resistance, possibly acting in the inhibition of the QacC efflux pump present in S. aureus strain K4100, as evidenced by the reduction in the MIC of ethidium bromide.

RESUMO

Spatial and temporal distributions and influencing factors of extreme precipitation are important bases for coping with future climate change. The spatiotemporal variability and affecting factors of extreme precipitation indices (EPIs) in east of northwest China (ENW) during 1961-2015 were investigated using a series of approaches such as modified Mann-Kendall trend test, Hurst exponent, ensemble empirical mode decomposition (EEMD), and geodetector model. The results showed that CDD and CWD decreased significantly (P < 0.01), with rates of 1.4 days/decade and 0.07 days/decade, respectively. EPIs in ENW exhibited an obvious heterogeneity. CDD gradually increased from the southeast to the northwest. The remaining EPIs generally showed the opposite trend. Geodetector results demonstrated that large-scale circulation factors had a significant impact on EPIs in ENW. The influence of large-scale climate factors on EPIs was concentrated in nonlinear enhancement, and Nino3.4 and SO were the dominant driving factors that played a major role in the variability of EPIs. The results of this study provided a reference for ENW and other arid and semi-arid regions to cope with extreme climates and develop corresponding strategies.

RESUMO

BACKGROUND: Patient navigation is an individualized intervention to facilitate comprehensive care which has not yet been fully implemented in obstetric or postpartum care. METHODS: We aimed to develop and evaluate a mechanism to incorporate feedback regarding implementation of postpartum patient navigation for low-income birthing individuals at an urban academic medical center. This study analyzed the role of an Implementation Advisory Board (IAB) in supporting an ongoing randomized trial of postpartum navigation. Over the first 24 months of the trial, the IAB included 11 rotating obstetricians, one clinic resource coordinator, one administrative leader, two obstetric nurses, one primary care physician, one social worker, and one medical assistant. Members completed serial surveys regarding program implementation, effects on patient care, and areas for improvement. Quarterly IAB meetings offered opportunities for additional feedback. Survey responses and meeting notes were analyzed using the constant comparative method and further interpreted within the Exploration, Preparation, Implementation, Sustainment (EPIS) Framework. RESULTS: Members of the IAB returned 37 surveys and participated in five meetings over 24 months. Survey analysis revealed four themes among the inner context: reduced clinician burden, connection of care teams, communication strategies, and clinic workflow. Bridging factors included improved patient access to care, improved follow-up, and adding social context to care. Innovation factors included availability of navigators, importance of consistent communication, and adaptation over time. Meeting notes highlighted the importance of bidirectional feedback regarding implementation, and members expressed positive opinions regarding navigators' effects on patient care, integration into clinic workflow, and responsiveness to feedback. IAB members initially suggested changes to improve implementation; later survey responses demonstrated successful program adaptations. CONCLUSIONS: Members of an implementation advisory board provided key insights into the implementation of postpartum patient navigation that may be useful to promote dissemination of navigation and establish avenues for the engagement of implementing partners in other innovations. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03922334 . Registered April 19, 2019. The results here do not present the results of the primary trial, which is ongoing.

RESUMO

Integrated behavioral health (IBH) in pediatric primary care settings can improve access to needed care and outcomes. Behavioral Health Workforce Education and Training (BHWET) programs can better prepare the workforce and support improved care access. This case study identified factors that impede and facilitate the implementation of practice-based training in a BHWET program using the Exploration, Preparation, Implementation, Sustainment (EPIS) framework. Surveys were administered to BHWET trainees and primary care partners to assess stakeholder perspectives on field-based training processes. Qualitative data were extracted from surveys and trainee clinical logs. Providers reported high levels of satisfaction with IBH care training experiences. Data analysis identified several implementation facilitators and barriers. Implementation facilitators were associated with two EPIS outer context factors (leadership and collaboration) and one inner context factor (partner staffing). Identified barriers were associated with two inner context factors (organizational characteristics and data collection). Although the facilitators and barriers identified in this study were program specific, they have relevance for similar programs. Barriers identified at the organizational level reflect those identified in the research literature and provide insights for university programs regarding factors that must be considered when integrating IBH training components in primary care settings.


Federally funded Behavioral Health Workforce Education and Training (BHWET) programs can better prepare the workforce and support integrated behavioral health (IBH) care in primary care settings. Using evaluation data gathered from primary care providers and trainees at partner clinics, this case study identified barriers that posed challenges to increasing behavioral health care for patients with identified needs, as well as factors that facilitated care. Barriers identified at the organizational level within partner clinics reflect those identified in the research literature and provide insights for medical professionals on factors they should consider when integrating behavioral health in primary care settings.
