2024 Systematic Review of Evidence-Based Guidelines for Prehospital Care.

OBJECTIVES: Evidence-based guidelines (EBGs) are widely recognized as valuable tools to aggregate and translate scientific knowledge into clinical care. High-quality EBGs can also serve as important components of dissemination and implementation efforts focused on educating emergency medical services (EMS) clinicians about current evidence-based prehospital clinical care practices and operations. We aimed to perform the third biennial systematic review of prehospital EBGs to identify and assess the quality of prehospital EBGs published since 2021. METHODS: We systematically searched Ovid Medline and EMBASE from January 1, 2021, to June 6, 2023, for publications relevant to prehospital care, based on an organized review of the literature, and focused on providing recommendations for clinical care or operations. Included guidelines were appraised using the National Academy of Medicine (NAM) criteria for high-quality guidelines and scored using the Appraisal of Guidelines for Research and Evaluation (AGREE) II Tool. RESULTS: We identified 33 new guidelines addressing clinical and operational topics of EMS medicine. The most addressed EMS core content areas were time-life critical conditions (n = 17, 51.5%), special clinical considerations (n = 15, 45%), and injury (n = 12, 36%). Seven (21%) guidelines included all elements of the National Academy of Medicine (NAM) criteria for high-quality guidelines, including the full reporting of a systematic review of the evidence. Guideline appraisals by the Appraisal of Guidelines for Research and Evaluation (AGREE) II tool demonstrated modest compliance to reporting recommendations and similar overall quality compared to previously identified guidelines (mean overall domain score 67%, SD 12%), with Domain 5 ("Applicability") scoring the lowest of the six AGREE II domains (mean score of 53%, SD 13%). CONCLUSIONS: This updated systematic review identified and appraised recent guidelines addressing prehospital care and identifies important targets for education of EMS personnel. Continued opportunities exist for prehospital guideline developers to include comprehensive evidence-based reporting into guideline development to facilitate widespread implementation of high-quality EBGs in EMS systems and incorporate the best available scientific evidence into initial education and continued competency activities.

A BTB-TAZ protein is required for gene activation by Cauliflower mosaic virus 35S multimerized enhancers.

The Arabidopsis (Arabidopsis thaliana) BTB-TAZ DOMAIN PROTEIN 2 (BT2) contains an N-terminal BTB domain, a central TAZ zinc-finger protein-protein interaction domain, and a C-terminal calmodulin-binding domain. We previously demonstrated that BT2 regulates telomerase activity and mediates multiple responses to nutrients, hormones, and abiotic stresses in Arabidopsis. Here, we describe the essential role of BT2 in activation of genes by multimerized Cauliflower mosaic virus 35S (35S) enhancers. Loss of BT2 function in several well-characterized 35S enhancer activation-tagged lines resulted in suppression of the activation phenotypes. Suppression of the phenotypes was associated with decreased transcript abundance of the tagged genes. Nuclear run-on assays, mRNA decay studies, and bisulfite sequencing revealed that BT2 is required to maintain the transcriptionally active state of the multimerized 35S enhancers, and lack of BT2 leads to hypermethylation of the 35S enhancers. The TAZ domain and the Ca++/calmodulin-binding domain of BT2 are critical for its function and 35S enhancer activity. We further demonstrate that BT2 requires CULLIN3 and two bromodomain-containing Global Transcription factor group E proteins (GTE9 and GTE11), to regulate 35S enhancer activity. We propose that the BT2-CULLIN3 ubiquitin ligase, through interactions with GTE9 and GTE11, regulates 35S enhancer activity in Arabidopsis.

Retrospective Cohort Study of Rates of Return Emergency Department Visits Among Patients Transported Home by Ambulance.

BACKGROUND: Emergency Medical Services (EMS) is an important resource that interacts with our most vulnerable patients during transport home after hospital discharge. EMS providers may be appropriately situated to support the transition of care to the home environment. OBJECTIVES: This study aimed to determine whether patients transported home by ambulance experience higher rates of return emergency department (ED) visits and readmission compared with similar patients transported home by other means. METHODS: This was a retrospective cohort study conducted at a U.S. tertiary care academic hospital. Patients aged 65 years and over transported home via ambulance after hospital discharge between January and March 2012 were included. Rates of 72-h and 30-day ED revisits and 30-day hospital readmissions were calculated. Odds ratios were calculated and revisit rates between groups were compared. RESULTS: There were 207 patients aged 65 and over transported home by ambulance. Matched controls were found for 162 patients. Compared with the matched controls, the exposed group experienced a statistically significant higher rate of 30-day ED returns (18.519% vs. 10.494%; odds ratio [OR] 1.939; p = 0.043). The exposed group also experienced a higher rate of 72-h ED returns (2.469% vs. 0.617%; OR 4.076) and 30-day readmissions (12.346% vs. 6.173%; OR 2.141), though results did not reach statistical significance. CONCLUSION: The study findings suggest that transport home via ambulance after hospital discharge could be predictive of a high risk of recidivism independent of established readmission risk factors. Programs that expand the role of EMS to include post-transport interventions may warrant further exploration.

Bromodomain proteins GTE9 and GTE11 are essential for specific BT2-mediated sugar and ABA responses in Arabidopsis thaliana.

KEY MESSAGE: Global Transcription Factor Group E proteins GTE9 and GTE11 interact with BT2 to mediate ABA and sugar responses in Arabidopsis thaliana. BT2 is a BTB-domain protein that regulates responses to various hormone, stress and metabolic conditions in Arabidopsis thaliana. Loss of BT2 results in plants that are hypersensitive to inhibition of germination by abscisic acid (ABA) and sugars. Conversely, overexpression of BT2 results in resistance to ABA and sugars. Here, we report the roles of BT2-interacting partners GTE9 and GTE11, bromodomain and extraterminal-domain proteins of Global Transcription Factor Group E, in BT2-mediated responses to sugars and hormones. Loss-of-function mutants, gte9-1 and gte11-1, mimicked the bt2-1-null mutant responses; germination of all three mutants was hypersensitive to inhibition by glucose and ABA. Loss of either GTE9 or GTE11 in a BT2 over-expressing line blocked resistance to sugars and ABA, indicating that both GTE9 and GTE11 were required for BT2 function. Co-immunoprecipitation of BT2 and GTE9 suggested that these proteins physically interact in vivo, and presumably function together to mediate responses to ABA and sugar signals.

Feasibility of the Transport PLUS intervention to improve the transitions of care for patients transported home by ambulance: a non-randomized pilot study.

BACKGROUND: The growing population of patients over the age of 65 faces particular vulnerability following discharge after hospitalization or an emergency room visit. Specific areas of concern include a high risk for falls and poor comprehension of discharge instructions. Emergency medical technicians (EMTs), who frequently transport these patients home from the hospital, are uniquely positioned to aid in mitigating transition of care risks and are both trained and utilized to do so using the Transport PLUS intervention. METHODS: Existing literature and focus groups of various stakeholders were utilized to develop two checklists: the fall safety assessment (FSA) and the discharge comprehension assessment (DCA). EMTs were trained to administer the intervention to eligible patients in the geriatric population. Using data from the checklists, follow-up phone calls, and electronic health records, we measured the presence of hazards, removal of hazards, the presence of discharge comprehension issues, and correction or reinforcement of comprehension. These results were validated during home visits by community health workers (CHWs). Feasibility outcomes included patient acceptance of the Transport PLUS intervention and accuracy of the EMT assessment. Qualitative feedback via focus groups was also obtained. Clinical outcomes measured included 3-day and 30-day readmission or ED revisit. RESULTS: One-hundred three EMTs were trained to administer the intervention and participated in 439 patient encounters. The intervention was determined to be feasible, and patients were highly amenable to the intervention, as evidenced by a 92% and 74% acceptance rate of the DCA and FSA, respectively. The majority of patients also reported that they found the intervention helpful (90%) and self-reported removing 40% of fall hazards; 85% of such changes were validated by CHWs. Readmission/revisit rates are also reported. CONCLUSIONS: The Transport PLUS intervention is a feasible, easily implemented tool in preventative community paramedicine with high levels of patient acceptance. Further study is merited to determine the effectiveness of the intervention in reducing rates of readmission or revisit. A randomized control trial has since begun utilizing the knowledge gained within this study.

Facilitating Long-Term Mentoring To Effectively Implement Active Learning Instruction: Formation of the Promoting Active Learning and Mentoring (PALM) Network.

A large body of data suggests that implementing active learning practices in a STEM classroom contributes to increased success in both achievement of student learning outcomes and retention of students. Despite these findings, significant barriers exist for instructors implementing active learning strategies in their undergraduate classrooms. These barriers can be effectively addressed by providing sustained support to instructors and postdoctoral trainees interested in implementing active learning strategies in their teaching practice. The Promoting Active Learning and Mentoring (PALM) network attains this objective by connecting instructors interested in learning more about active learning (Fellows) with individuals who have extensive expertise related to this practice (mentors). These facilitated connections occur in the form of active mentorship for a year or more, virtual journal clubs, and biannual gatherings of PALM Fellows and mentors. Here, we describe the foundation on which PALM was built and explain how a successful mentorship program can pave the way for educators to adapt and implement evidence-based practices like active learning in a college classroom.

Opportunities for addressing gaps in primary care shared decision-making with technology: a mixed-methods needs assessment.

OBJECTIVES: To analyze current practices in shared decision-making (SDM) in primary care and perform a needs assessment for the role of information technology (IT) interventions. MATERIALS AND METHODS: A mixed-methods study was conducted in three phases: (1) ethnographic observation of clinical encounters, (2) patient interviews, and (3) physician interviews. SDM was measured using the validated OPTION scale. Semistructured interviews followed an interview guide (developed by our multidisciplinary team) informed by the Traditional Decision Conflict Scale and Shared Decision Making Questionnaire. Field notes were independently coded and analyzed by two reviewers in Dedoose. RESULTS: Twenty-four patient encounters were observed in 3 diverse practices with an average OPTION score of 57.2 (0-100 scale; 95% confidence interval [CI], 51.8-62.6). Twenty-two patient and 8 physician interviews were conducted until thematic saturation was achieved. Cohen's kappa, measuring coder agreement, was 0.42. Patient domains were: establishing trust, influence of others, flexibility, frustrations, values, and preferences. Physician domains included frustrations, technology (concerns, existing use, and desires), and decision making (current methods used, challenges, and patients' understanding). DISCUSSION: Given low SDM observed, multiple opportunities for technology to enhance SDM exist based on specific OPTION items that received lower scores, including: (1) checking the patient's preferred information format, (2) asking the patient's preferred level of involvement in decision making, and (3) providing an opportunity for deferring a decision. Based on data from interviews, patients and physicians value information exchange and are open to technologies that enhance communication of care options. CONCLUSION: Future primary care IT platforms should prioritize the 3 quantitative gaps identified to improve physician-patient communication and relationships. Additionally, SDM tools should seek to standardize common workflow steps across decisions and focus on barriers to increasing adoption of effective SDM tools into routine primary care.

Broadening Participation in Biology Education Research: Engaging Community College Students and Faculty.

Nearly half of all undergraduates are enrolled at community colleges (CCs), including the majority of U.S. students who represent groups underserved in the sciences. Yet only a small minority of studies published in discipline-based education research journals address CC biology students, faculty, courses, or authors. This marked underrepresentation of CC biology education research (BER) limits the availability of evidence that could be used to increase CC student success in biology programs. To address this issue, a diverse group of stakeholders convened at the Building Capacity for Biology Education Research at Community Colleges meeting to discuss how to increase the prevalence of CC BER and foster participation of CC faculty as BER collaborators and authors. The group identified characteristics of CCs that make them excellent environments for studying biology teaching and learning, including student diversity and institutional cultures that prioritize teaching, learning, and assessment. The group also identified constraints likely to impede BER at CCs: limited time, resources, support, and incentives, as well as misalignment between doing research and CC faculty identities as teachers. The meeting culminated with proposing strategies for faculty, administrators, journal editors, scientific societies, and funding agencies to better support CC BER.

The inclusion of minority groups in clinical trials: problems of under representation and under reporting of data.

OBJECTIVE: To evaluate the representation of minority groups in randomized control trials (RCTs), and the frequency with which this information is reported. STUDY DESIGN: Reviewers collected data on the racial/ethnic composition of study samples from all RCTs published in six leading medical journals in 1999. RESULTS: Of the 280 RCTs, most (204, 71.3%) provided no information on the race/ethnicity of participants. Of the 89 U.S.-based RCTs, 50 (56.1%) reported their minority distribution. Relative to other trials, those funded by the National Institute of Health (NIH) (n = 52) were more likely to report race/ethnicity data (55.8% vs. 23.7%; x2 = 20.9, p <_0.001) and to include nonwhite participants (13.5 % vs. 12.5%; x2=22.7, p<_0.001). CONCLUSION: Minority groups are currently under-represented in clinical trials. Information on the race and ethnicity of clinical trial participants is currently underreported in six leading medical journals. Reporting of minority group information was significantly better only in NIH funded trials, which also were more likely to include nonwhite participants. This suggests that mandatory reporting policies may have a positive effect on both reporting and representation.

BT2, a BTB protein, mediates multiple responses to nutrients, stresses, and hormones in Arabidopsis.

The Arabidopsis (Arabidopsis thaliana) gene BT2 encodes a 41-kD protein that possesses an amino-terminal BTB domain, a central TAZ domain, and a carboxyl-terminal calmodulin-binding domain. We previously demonstrated that BT2 could activate telomerase expression in mature Arabidopsis leaves. Here, we report its distinct role in mediating diverse hormone, stress, and metabolic responses. We serendipitously discovered that steady-state expression of BT2 mRNA was regulated diurnally and controlled by the circadian clock, with maximum expression in the dark. This pattern of expression suggested that BT2 mRNA could be linked to the availability of photosynthate in the plant. Exogenous sugars decreased BT2 expression, whereas exogenous nitrogen increased expression. bt2 loss-of-function mutants displayed a hypersensitive response to both sugar-mediated inhibition of germination and abscisic acid (ABA)-mediated inhibition of germination, thus supporting a role of ABA in sugar signaling in germination and development. Moreover, constitutive expression of BT2 imparted resistance to both sugars and ABA at germination, suggesting that BT2 suppresses sugar and ABA responses. In support of the previously described antagonistic relationship between ABA and auxin, we found that BT2 positively regulated certain auxin responses in plants, as revealed by knocking down BT2 expression in the high-auxin mutant yucca. Accumulation of BT2 mRNA was affected by a variety of hormones, nutrients, and stresses, and BT2 was required for responses to many of these same factors. Together, these results suggest that BT2 is a central component of an interconnected signaling network that detects and responds to multiple inputs.

Relation between randomized controlled trials published in leading general medical journals and the global burden of disease.

BACKGROUND: More than two-thirds of the world's population live in low-income countries, where health priorities are different from those of people living in more affluent parts of the world. We evaluated the relation between the global burden of disease and conditions or diseases studied in randomized controlled trials (RCTs) published in general medical journals. METHODS: A MEDLINE search identified 373 RCTs that had been published in 6 international peer-reviewed general medical journals in 1999. Manual review excluded non-RCTs, brief reports and trials in which the unit of randomization was not the patient; 286 RCTs remained eligible for analysis. We identified the RCTs that studied any of the 40 leading causes of the global burden of disease. Five of these conditions were considered unsuitable for study with an RCT design and were excluded from subsequent analysis. To provide a practical perspective, we asked 12 experts working with international health organizations to rate the relevance to global health of the articles that studied any of the top 10 causes of the global burden of disease, as measured by disability-adjusted life years (DALYs) and mortality, using a 5-point Likert scale. RESULTS: Among the 286 RCTs in our sample, 124 (43.4%) addressed 1 of the 35 leading causes of the global burden of disease. Of these, ischemic heart disease, HIV/AIDS and cerebrovascular disease were the most commonly studied conditions. Ninety articles (31.5%) studied 1 of the top 10 causes of the global burden of disease. The mean rating (and standard deviation) for international health relevance assigned by experts was 2.6 (1.5) out of 5. Only 14 (16%) of the 90 trials received a rating of 4 or greater, indicating high relevance to international health. Almost half of the 40 leading causes of the global burden of disease were not studied by any trial. INTERPRETATION: Many conditions or diseases common internationally are underrepresented in RCTs published in leading general medical journals. Trials published in these journals that studied one of these high-priority conditions were generally rated as being of little relevance to international health.
