Identifying factors and causal chains associated with optimal implementation of Lynch syndrome tumor screening: An application of coincidence analysis.

PURPOSE: This study compared Lynch syndrome universal tumor screening (UTS) across multiple health systems (some of which had 2 or more distinct UTS programs) to understand multilevel factors that may affect the successful implementation of complex programs. METHODS: Data from 66 stakeholder interviews were used to conduct multivalue coincidence analysis and identify key factors that consistently make a difference in whether UTS programs were implemented and optimized at the system level. RESULTS: The selected coincidence analysis model revealed combinations of conditions that distinguish 4 optimized UTS programs, 10 nonoptimized programs, and 4 systems with no program. Fully optimized UTS programs had both a maintenance champion and a positive inner setting. Two independent paths were unique to nonoptimized programs: (1) positive attitudes and a mixed inner setting or (2) limited planning and engaging among stakeholders. Negative views about UTS evidence or lack of knowledge about UTS led to a lack of planning and engaging, which subsequently prevented program implementation. CONCLUSION: The model improved our understanding of program implementation in health care systems and informed the creation of a toolkit to guide UTS implementation, optimization, and changes. Our findings and toolkit may serve as a use case to increase the successful implementation of other complex precision health programs.

COVID-19 clinical trials: who is likely to participate and why?

Aim: To identify factors associated with willingness to participate in a COVID-19 clinical trial and reasons for and against participating. Materials & methods: We surveyed Massachusetts (MA, USA) residents online using the Dynata survey platform and via phone using random digit dialing between October and November 2021. Respondents were asked to imagine they were hospitalized with COVID-19 and invited to participate in a treatment trial. We assessed willingness to participate by asking, "Which way are you leaning" and why. We used multivariate logistic regression to model factors associated with leaning toward participation. Open-ended responses were analyzed using conventional content analysis. Results: Of 1071 respondents, 65.6% leaned toward participating. Multivariable analyses revealed college-education (OR: 1.59; 95% CI: 1.11, 2.27), trust in the healthcare system (OR: 1.32; 95% CI: 1.10, 1.58) and relying on doctors (OR: 1.77; 95% CI: 1.45, 2.17) and family or friends (OR: 1.31; 95% CI: 1.11, 1.54) to make health decisions were significantly associated with leaning toward participating. Respondents with lower health literacy (OR: 0.57; 95% CI: 0.36, 0.91) and who identify as Black (OR: 0.40; 95% CI: 0.24, 0.68), Hispanic (OR: 0.61; 95% CI: 0.38, 0.98), or republican (OR: 0.61; 95% CI: 0.38, 0.97) were significantly less likely to lean toward participating. Common reasons for participating included helping others, benefitting oneself and deeming the study low risk. Common reasons for leaning against were deeming the study high risk, disliking experimental treatments and not wanting to be a guinea pig. Conclusion: Our finding that vulnerable individuals and those with lower levels of trust in the healthcare system are less likely to be receptive to participating in a COVID-19 clinical trial highlights that work is needed to achieve a healthcare system that provides confidence to historically disadvantaged groups that their participation in research will benefit their community.

Long COVID awareness and receipt of medical care: a survey among populations at risk for disparities.

Introduction: The COVID-19 pandemic has been characterized by disparities in disease burden and medical care provision. Whether these disparities extend to long COVID awareness and receipt of medical care is unknown. We aimed to characterize awareness of long COVID and receipt of medical care for long COVID symptoms among populations who experience disparities in the United States (US). Methods: We conducted a cross-sectional survey among a national sample of US adults between January 26-February 5, 2023. We surveyed approximately 2,800 adults drawn from the Ipsos probability-based KnowledgePanel® who identify as White, Black, or Hispanic, with over-sampling of Black, Hispanic, and Spanish-proficient adults. Awareness of long COVID was assessed with the question, "Have you heard of long COVID? This is also referred to as post-COVID, Long-haul COVID, Post-acute COVID-19, or Chronic COVID." Respondents reporting COVID-19 symptoms lasting longer than 1 month were classified as having long COVID and asked about receipt of medical care. Results: Of the 2,828 respondents, the mean age was 50.4 years, 52.8% were female, 40.2% identified as Hispanic, 29.8% as Black, and 26.7% as White. 18% completed the survey in Spanish. Overall, 62.5% had heard of long COVID. On multivariate analysis, long COVID awareness was lower among respondents who identified as Black (OR 0.64; 95% CI 0.51, 0.81), Hispanic and completed the survey in English (OR 0.59; 95% CI 0.46, 0.76), and Hispanic and completed the survey in Spanish (OR 0.31, 95% C.I. 0.23, 0.41), compared to White respondents (overall p < 0.001). Long COVID awareness was also associated with educational attainment, higher income, having health insurance, prior history of COVID-19 infection, and COVID-19 vaccination. Among those reporting symptoms consistent with long COVID (n = 272), 26.8% received medical care. Older age, longer symptom duration and greater symptom impact were associated with receipt of medical care for long COVID symptoms. Of those who received care, most (77.8%) rated it as less than excellent on a 5-point scale. Discussion: This survey reveals limited awareness of long COVID and marked disparities in awareness according to race, ethnicity, and language. Targeted public health campaigns are needed to raise awareness.

Explicit Training in Systematic Communication Strategies: A Pilot Study Exploring the Incorporation of Communication Tools by First-Year Residents in Simulation and in Clinical Practice.

OBJECTIVES: Educational approaches for training physicians in clinical communications vary, and whether physicians apply the communication skills they learn or find them useful in the clinic is not well known. The aim of this study was to determine how first-year residents who received explicit instruction in 7 communication strategies would apply them in a simulation exercise and in clinical practice. METHODS: First-year Internal Medicine residents at an urban teaching hospital received instruction in 7 systematic communication strategies: Ask-Tell-Ask, Teach-back, open-ended questioning, NURSE, open body language, pausing, and plain language. Residents were evaluated on their use of specific communication behaviors associated with the 7 strategies during a simulation exercise of disclosing a medical error to a standardized patient. Control group residents who did the simulation before attending the training program and training group residents who did the simulation after the training were compared. Residents were queried 6 months after the training program on their use of communication strategies during clinical practice. RESULTS: A total of 27 residents participated (n = 13 control group; n = 14 training group). The training group performed behaviors for "establishing patient understanding" significantly more often than the control group. Both groups used non-verbal communication and behaviors for addressing patient emotions at similar levels. Of the 24 residents who responded to the 6-month follow-up questionnaire, 24 (100%) reported using Ask-Tell-Ask, open-ended questioning, and Teach-back, and 22 (92%) reported using NURSE statements and non-verbal communication. Most respondents reported using the strategies in clinical practice often or very often (79%) and found the strategies useful or very useful (96%). CONCLUSION: Providing explicit instruction in systematic communication strategies, particularly those focused on establishing patient understanding, may be an efficient approach for helping early career physicians develop effective communication skills that can be readily implemented during clinical training and practice.

Persist or Perish: Can Bats Threatened with Extinction Persist and Recover from White-nose Syndrome?

Emerging mycoses are an increasing concern in wildlife and human health. Given the historical rarity of fungal pathogens in warm-bodied vertebrates, there is a need to better understand how to manage mycoses and facilitate recovery in affected host populations. We explore challenges to host survival and mechanisms of host recovery in three bat species (Myotis lucifugus, Perimyotis subflavus, and M. septentrionalis) threatened with extinction by the mycosis, white-nose syndrome (WNS) as it continues to spread across North America. We present evidence from the literature that bats surviving WNS are exhibiting mechanisms of avoidance (by selecting microclimates within roosts) and tolerance (by increasing winter fat reserves), which may help avoid costs of immunopathology incurred by a maladaptive host resistance response. We discuss management actions for facilitating species recovery that take into consideration disease pressures (e.g., environmental reservoirs) and mechanisms underlying persistence, and suggest strategies that alleviate costs of immunopathology and target mechanisms of avoidance (protect or create refugia) and tolerance (increase body condition). We also propose strategies that target population and species-level recovery, including increasing reproductive success and reducing other stressors (e.g., wind turbine mortality). The rarity of fungal pathogens paired with the increasing frequency of emerging mycoses in warm-bodied vertebrate systems, including humans, requires a need to challenge common conventions about how diseases operate, how hosts respond, and how these systems could be managed to increase probability of recovery in host populations.

Ecological countermeasures to prevent pathogen spillover and subsequent pandemics.

Substantial global attention is focused on how to reduce the risk of future pandemics. Reducing this risk requires investment in prevention, preparedness, and response. Although preparedness and response have received significant focus, prevention, especially the prevention of zoonotic spillover, remains largely absent from global conversations. This oversight is due in part to the lack of a clear definition of prevention and lack of guidance on how to achieve it. To address this gap, we elucidate the mechanisms linking environmental change and zoonotic spillover using spillover of viruses from bats as a case study. We identify ecological interventions that can disrupt these spillover mechanisms and propose policy frameworks for their implementation. Recognizing that pandemics originate in ecological systems, we advocate for integrating ecological approaches alongside biomedical approaches in a comprehensive and balanced pandemic prevention strategy.

Inhibitory protein-protein interactions of the SIRT1 deacetylase are choreographed by post-translational modification.

Regulation of SIRT1 activity is vital to energy homeostasis and plays important roles in many diseases. We previously showed that insulin triggers the epigenetic regulator DBC1 to prime SIRT1 for repression by the multifunctional trafficking protein PACS-2. Here, we show that liver DBC1/PACS-2 regulates the diurnal inhibition of SIRT1, which is critically important for insulin-dependent switch in fuel metabolism from fat to glucose oxidation. We present the x-ray structure of the DBC1 S1-like domain that binds SIRT1 and an NMR characterization of how the SIRT1 N-terminal region engages DBC1. This interaction is inhibited by acetylation of K112 of DBC1 and stimulated by the insulin-dependent phosphorylation of human SIRT1 at S162 and S172, catalyzed sequentially by CK2 and GSK3, resulting in the PACS-2-dependent inhibition of nuclear SIRT1 enzymatic activity and translocation of the deacetylase in the cytoplasm. Finally, we discuss how defects in the DBC1/PACS-2-controlled SIRT1 inhibitory pathway are associated with disease, including obesity and non-alcoholic fatty liver disease.

Geographically widespread and novel hemotropic mycoplasmas and bartonellae in Mexican free-tailed bats and sympatric North American bat species.

Bacterial pathogens remain poorly characterized in bats, especially in North America. We describe novel (and in some cases panmictic) hemoplasmas (12.9% positivity) and bartonellae (16.7% positivity) across three colonies of Mexican free-tailed bats (Tadarida brasiliensis), a partially migratory species that can seasonally travel hundreds of kilometers. Molecular analyses identified three novel Candidatus hemoplasma species most similar to another novel Candidatus species in Neotropical molossid bats. We also detected novel hemoplasmas in sympatric cave myotis (Myotis velifer) and pallid bats (Antrozous pallidus), with sequences in the latter 96.5% related to C. Mycoplasma haemohominis. We identified eight Bartonella genotypes, including those in cave myotis, with 96.7% similarity to C. Bartonella mayotimonensis. We also detected Bartonella rochalimae in migratory Tadarida brasiliensis, representing the first report of this human pathogen in bats. The seasonality and diversity of these bacteria observed here suggest that additional longitudinal, genomic, and immunological studies in bats are warranted.

Multiple myeloma incidence, mortality, and survival differences at the intersection of sex, age, and race/ethnicity: A comparison between Puerto Rico and the United States SEER population.

BACKGROUND: Multiple myeloma (MM) survival has increased during the last decades due to the introduction of new therapies. We investigated the intersectionality among age, sex, and race/ethnicity to better understand the pattern of MM incidence, mortality, and survival. METHODS: Puerto Rico (PR) Central Cancer Registry and the United States of America (US) Surveillance, Epidemiology, and End Results (SEER) Program databases were used. We analyzed MM incidence and mortality trends from 2001 to 2019 using Joinpoint regression models to calculate annual percent change (APC). Age-standardized rate ratios (SRR) for incidence and mortality were used to compare PR with US SEER racial/ethnic groups during 2015-2019. Five-year survival analyses were also performed stratified by age and sex. RESULTS: Regardless of age and race/ethnicity, males had higher MM incidence and mortality rates than females. PR had a higher increase in incidence rates of MM than other ethnic groups, regardless of sex and age (PR APC = 4.3 among males <65, 3.1 among males ≥65, 6.3 among females <65, and 2.6 among females ≥65 years old). No significant change in mortality APCs (p > 0.05) was observed in PR when stratified by age or sex while other groups showed a decrease. Among males < 65 years, PR had significantly higher incidence rates than non-Hispanic Whites (NHW), and US Hispanics (USH). However, among both males and females ≥ 65 years, PR had significantly lower MM mortality rates than NHW, non-Hispanic Blacks (NHB), USH, and US Overall. In terms of survival, PR showed the lowest 5-year overall survival among males < 65 years (54.6%, 95% CI: 47.2-61.5) and males ≥ 65 years (34.5%, 95% CI: 29.2-39.9) but not among females. CONCLUSION: The incidence of MM in PR increased significantly over the study period, particularly among younger women. Despite the introduction of new therapies, mortality rates in PR have remained stable while other ethnic groups show significant decreases among all intersections of sex and age.

Gathering Trainee Feedback to Improve Programs With Low Annual ACGME Survey Content Area Compliance: A Pilot Study.

PROBLEM: Systematically investigating annual Accreditation Council for Graduate Medical Education (ACGME) Resident/Fellow Survey results by directly gathering trainee feedback could uncover training program problems and clarify misunderstandings as they arise, leading to faster corrective actions and program improvement. APPROACH: The Focus Group Forum (FGF) was created based on the utilization-focused evaluation approach to systematically gather comprehensive, high-quality, actionable trainee feedback on specific annual ACGME survey results and involve trainees in program improvement (Henry Ford Hospital, 2021). Trainees from programs with survey results indicating <80% compliance within several content areas were invited to attend FGF sessions. During FGF sessions, neutral moderators experienced in conducting focus groups and creating psychologically safe spaces and neutral scribes gathered trainee feedback on survey results through structured, iterative discussions and an anonymous electronic polling system. Summaries of FGF findings were created, combined with actual annual ACGME survey data, and used to develop recommended corrective actions and monitoring plans. OUTCOMES: In 2021, 6 training programs had survey results below the institution's compliance threshold for 4-8 of the 9 content areas. Of the 180 trainees (from the 6 programs) invited to attend an FGF session, 79 (44%) participated. Five key issues were identified: misinterpretation of several survey questions, lack of knowledge of institutional policies and procedures, perceived inability to share feedback with faculty, feelings of being overwhelmed with administrative duties, and lack of sufficient protected time for educational activities and requirements. NEXT STEPS: The authors are developing an FGF process for faculty so that all stakeholders have a voice regarding annual ACGME survey results. They are also improving scheduling processes so that feedback from experienced trainees who are leaving the institution will not be missed and developing longer-term processes for tracking outcomes since time for implementing corrective actions before the next ACGME survey is limited.

Robust evidence for bats as reservoir hosts is lacking in most African virus studies: a review and call to optimize sampling and conserve bats.

Africa experiences frequent emerging disease outbreaks among humans, with bats often proposed as zoonotic pathogen hosts. We comprehensively reviewed virus-bat findings from papers published between 1978 and 2020 to evaluate the evidence that African bats are reservoir and/or bridging hosts for viruses that cause human disease. We present data from 162 papers (of 1322) with original findings on (1) numbers and species of bats sampled across bat families and the continent, (2) how bats were selected for study inclusion, (3) if bats were terminally sampled, (4) what types of ecological data, if any, were recorded and (5) which viruses were detected and with what methodology. We propose a scheme for evaluating presumed virus-host relationships by evidence type and quality, using the contrasting available evidence for Orthoebolavirus versus Orthomarburgvirus as an example. We review the wording in abstracts and discussions of all 162 papers, identifying key framing terms, how these refer to findings, and how they might contribute to people's beliefs about bats. We discuss the impact of scientific research communication on public perception and emphasize the need for strategies that minimize human-bat conflict and support bat conservation. Finally, we make recommendations for best practices that will improve virological study metadata.

"Go ahead and screen" - advice to healthcare systems for routine lynch syndrome screening from interviews with newly diagnosed colorectal cancer patients.

BACKGROUND: Lynch syndrome (LS) is the most common cause of inherited colorectal cancer (CRC). Universal tumor screening (UTS) of newly diagnosed CRC cases is recommended to aid in diagnosis of LS and reduce cancer-related morbidity and mortality. However, not all health systems have adopted UTS processes and implementation may be inconsistent due to system and patient-level complexities. METHODS: To identify barriers, facilitators, and suggestions for improvements of the UTS process from the patient perspective, we conducted in-depth, semi-structured interviews with patients recently diagnosed with CRC, but not screened for or aware of LS. Patients were recruited from eight regionally diverse US health systems. Interviews were conducted by telephone, 60-minutes, audio-recorded, and transcribed. An inductive, constant comparative analysis approach was employed.  RESULTS: We completed 75 interviews across the eight systems. Most participants were white (79%), about half (52%) were men, and the mean age was 60 years. Most self-reported either no (60%) or minimal (40%) prior awareness of LS. Overall, 96% of patients stated UTS should be a routine standard of care for CRC tumors, consistently citing four primary motivations for wanting to know their LS status and engage in the process for LS identification: "knowledge is power"; "family knowledge"; "prevention and detection"; and "treatment and surveillance." Common concerns pertaining to the process of screening for and identifying LS included: creating anticipatory worry for patients, the potential cost and the accuracy of the genetic test, and possibly having one's health insurance coverage impacted by the LS diagnosis. Patients suggested health systems communicate LS results in-person or by phone from a trained expert in LS; offer proactive verbal and written education about LS, the screening steps, and any follow-up surveillance recommendations; and support patients in communicating their LS screening to any of their blood relatives. CONCLUSION: Our qualitative findings demonstrate patients with CRC have a strong desire for healthcare systems to regularly implement and offer UTS. Patients offer key insights for health systems to guide future implementation and optimization of UTS and other LS screening programs and maximize diagnosis of individuals with LS and improve cancer-related surveillance and outcomes. TRIAL REGISTRATION: Not available: not a clinical trial.

Assessing the impact of a 6-year health sciences enrichment program for underrepresented minority youth on healthcare workforce diversity, career path, and public health.

Background: Improving the quality of care for a diverse population requires a diverse healthcare workforce which necessitates high educational attainment among underrepresented communities. Programs aimed to address healthcare workforce diversity gaps also serve as a public health intervention by offering avenues to improve the health of local communities by providing students with the knowledge and skills to promote healthy behaviors, foster scientific literacy, and inspire future public health professionals - who in turn serve their local communities to advance health outcomes. We interviewed alumni of the New York Presbyterian Hospital Lang Youth Medical Program (LYMP), a high school health sciences mentoring and enrichment program for underrepresented minority youth in Upper Manhattan, from graduating classes between 2012 and 2021 to explore their perspectives on what aspects of the program had the most impact on their academic and career paths. Method: This is a qualitative study using in-depth, semi-structured individual interviews. All interviews were analyzed using the constant comparative method for developing grounded theory, following a convenience sampling method. Results: 106 codes were organized into 24 themes, which were further arranged into 4 topic areas: demonstrated program success, intangible program drivers, improvement opportunities, and barriers to program participation. Topic areas captured participants' perspectives on how the program is designed to foster an environment of personal, academic, and professional development; ways aspects of the program organically worked together to provide unanticipated positive facilitators; opportunities for program improvements, and external factors that influenced decision-making. Conclusion: Through this study, we found that the LYMP had a positive influence in helping participants set and achieve personal, academic, and professional goals. Alumni reported activities and experiences offered by the program that foster key youth development constructs linked to healthier and more resilient communities. Importantly, the vast majority of participants described how the synergism between program features, staff support, family involvement, and professional development and networking created an environment of achievement that went beyond the scope of the program design. Findings from this study offer a blueprint for other organizations to craft a similarly successful enrichment program that improves health outcomes, reduces health disparities, and promotes overall population health.

Electrochemical and theoretical study on interaction between erlotinib and DNA.

A comprehensive investigation of tyrosine kinase inhibitor erlotinib (ERL) electrochemical behavior and interaction with DNA was performed with the aim to clarify its redox mechanism and to determine the mode of binding. Irreversible oxidation and reduction processes of ERL on glassy carbon electrode were investigated using three voltammetric techniques CV, DPV, SWV in pH range between 2.0 and 9.0. Oxidation was established as an adsorption-controlled process, while the reduction manifested diffusion-adsorption mixed controlled process in acidic medium and adsorption became predominant in the neutral solutions. According to the determined number of transferred electrons and protons, oxidation and reduction mechanism of ERL are proposed. To follow the interaction between ERL and DNA, the multilayer ct-DNA electrochemical biosensor was incubated in ERL solutions concentrations ranged from 2 × 10-7 M to 5 × 10-5 M (pH 4.6) for 30 min. SWV measurements have shown the decrease in deoxyadenosine peak current as a consequence of ERL increased concentration and binding to ct-DNA. The calculated value of binding constant was K = 8.25 × 104 M-1. Molecular docking showed that ERL forms hydrophobic interactions when docked into minor groove, as well as when intercalated, and molecular dynamics analysis predicted the stability of obtained complexes. These results together with voltammetric studies imply that the intercalation could be more dominant way ERL binding to DNA compared to minor groove binding.

Evaluation of the quality of meat and carcasses from sheep fed diets containing three types of oils.

The objective of this research was to evaluate the quantitative and qualitative characteristics of the carcass and meat of lambs fed with different types of oil. Thirty male, uncastrated, mixed breed (Santa Inês × Dorper) sheep were used in this experiment and were distributed in random blocks with three treatments and 10 replicates per treatment, where each animal represents a replicated experimental unit. The three treatments were the following experimental diets: soybean oil in natura; soybean oil after use in frying, and palm oil (Elaeis guineensis). The oils were incorporated into the sheep diets at a level of 4%. Carcasses were evaluated for hot and cold yield, loss due to cooling, finish, conformation, internal fat concentration, morphometric measurements, tissue composition, and commercial cuts. The addition of soybean oil in natura, residual soybean oil from frying, and palm oil to the sheep diets did not alter any of the evaluated characteristics, which therefore can be interpreted as favoring the use of any of these three oils as a supplement to their diet, and the three oils imparted good characteristics to the carcasses and the meat.

The perinatal outcomes of women treated for Asherman syndrome: a propensity score-matched cohort study.

STUDY QUESTION: Do the perinatal outcomes of patients following hysteroscopic treatment for Asherman syndrome (AS) differ from that of a control population? SUMMARY ANSWER: Perinatal complications including placental issues, high blood loss, and prematurity in women after treatment for AS should be considered as moderate to high risk, especially in patients who have undergone more than one hysteroscopy (HS) or repeated postpartum instrumental revisions of the uterine cavity (Dilation and Curettage; D&C). WHAT IS KNOWN ALREADY: The detrimental impact of AS on obstetrics outcomes is commonly recognized. However, prospective studies evaluating perinatal/neonatal outcomes in women with AS history are sparse, and the characteristics accounting for the respective morbidity of AS patients remain to be elucidated. STUDY DESIGN, SIZE, DURATION: We conducted a prospective cohort study utilizing data from patients who underwent HS treatment for moderate to severe AS in a single tertiary University-affiliated hospital (enrolled between 01 January 2009 and March 2021), and who consequently conceived and progressed to at least 22nd gestational week of pregnancy. Perinatal outcomes were compared to a control population without an AS history, retrospectively enrolled concomitantly at the time of delivery for each patient with AS. Maternal and neonatal morbidity was assessed as well as the characteristics-related risk factors of AS patients. PARTICIPANTS/MATERIALS, SETTING, METHODS: Our analytic cohort included a total of 198 patients, 66 prospectively enrolled patients with moderate to severe AS and 132 controls. We used multivariable logistic regression to calculate a propensity score to match 1-1 women with and without AS history based on demographic and clinical factors. After matching, 60 pairs of patients were analysed. Chi-square test was used to compare perinatal outcomes between the pairs. Spearman's correlation analysis was utilized to investigate the correlation between perinatal/neonatal morbidity and the characteristics-related factors of AS patients. The odds ratio (OR) for the associations was calculated by logistic regression. MAIN RESULTS AND THE ROLE OF CHANCE: Among the 60 propensity matched pairs, the AS group more frequently experienced overall perinatal morbidity, including abnormally invasive placenta (41.7% vs 0%; P < 0.001), retained placenta requiring manual or surgical removal (46.7% vs 6.7%; P < 0.001), and peripartum haemorrhage occurrence (31.7% vs 3.3%; P < 0.001). Premature delivery (<37 gestational weeks) was reported more frequently also for patients with AS (28.3% vs 5.0%; P < 0.001). However, no increased frequency of intra-uterine growth restriction or worsened neonatal outcomes were observed in AS group. Univariable analysis of risk factors for AS group morbidity outcomes revealed that the main factor related to abnormally invasive placenta was two or more HS procedures (OR 11.0; 95% CI: 1.33-91.23), followed by two or more D&Cs preceding AS treatment (OR 5.11; 95% CI: 1.69-15.45), and D&C performed postpartum as compared to post abortion (OR 3.0; 95% CI: 1.03-8.71). Similarly, two or more HS procedures were observed as the most important factor for retained placenta (OR 13.75; 95% CI: 1.66-114.14), followed by two or more preceding D&Cs (OR 5.16; 95% CI: 1.67-15.9). Premature birth was significantly associated with the number of preceding D&Cs (OR for two or more, 4.29; 95% CI: 1.12-14.91). LIMITATIONS, REASONS FOR CAUTION: Although the cohort of patients with AS was enrolled prospectively, a baseline imbalance was intrinsically involved in the retrospective enrolment of the control group. However, to reduce the risk of bias, confounding factors were adjusted for using propensity score matching. The limitation to the generalization of our reported results is the single institution design in which all patients were treated for AS in one tertiary medical centre. WIDER IMPLICATIONS OF THE FINDINGS: Within our search scope, our study represents one of the first and largest prospective studies of perinatal and neonatal outcomes in moderate to severe AS patients with a prospectively analysis of the risks factors of characteristics significantly influencing reported morbidities among patients with AS. STUDY FUNDING/COMPETING INTEREST(S): The study was supported by the Charles University in Prague [UNCE 204065] and by the institutional grant of The General Faculty Hospital in Prague [00064165]. No competing interests were declared. TRIAL REGISTRATION NUMBER: N/A.

Current State of Peer Learning in Radiology: A Survey of ACR Members.

PURPOSE: Peer learning (PL) programs seek to improve upon the limitations of score-based peer review and incorporate modern approaches to improve patient care. The aim of this study was to further understand the landscape of PL among members of the ACR in the first quarter of 2022. METHODS: Members of the ACR were surveyed to evaluate the incidence, current practices, perceptions, and outcomes of PL in radiology practice. The survey was administered via e-mail to 20,850 ACR members. The demographic and practice characteristics of the 1,153 respondents (6%) were similar to those of the ACR radiologist membership and correspond to a normal distribution of the population of radiologists and can therefore be described as representative of that population. Therefore, the error range for the results from this survey is ±2.9% at a 95% confidence level. RESULTS: Among the total sample, 610 respondents (53%) currently use PL, and 334 (29%) do not. Users of PL are younger (mode age ranges, 45-54 years for users and 55-64 years for nonusers; P < .01), more likely to be female (29% vs 23%, P < .05), and more likely to practice in urban settings (52% vs 40%, P = .0002). Users of PL feel that it supports an improved culture of safety and wellness (543 of 610 [89%]) and fosters continuous improvement initiatives (523 of 610 [86%]). Users of PL are more likely than nonusers to identify learning opportunities from routine clinical practice (83% vs 50%, P < .00001), engage in programming inclusive of more team members, and implement more practice improvement projects (P < .00001). PL users' net promoter score of 65% strongly suggests that users of PL are highly likely to recommend the program to colleagues. CONCLUSIONS: Radiologists across a breadth of radiology practices are engaged in PL activities, which are perceived to align with emerging principles of improving health care and enhance culture, quality, and engagement.
