ABSTRACT

OBJECTIVES: In 2020, a list of Key Potentially Inappropriate Drugs in Pediatrics, known as the "KIDs List," was published. The objective of this analysis was to evaluate institutional compliance with the -recommendations in this publication and identify areas for improvement. METHODS: Medications in the KIDs List were compared to the institutional formulary at a large academic medical center caring for pediatric and adult patients. Medications listed in the formulary were then -evaluated for order comments and restrictions related to their use in pediatric patients. Oral liquid products and a group of commonly used intravenous (IV) medications were reviewed for potentially inappropriate excipients through available manufacturer information. The pediatric clinical specialists were then solicited to review and make recommendations for medications that had not been addressed. RESULTS: Of the 67 medications or classes listed in the KIDs List, 47 (70.1%) of the medications are listed in our formulary and available for use. Of these 47 medications, 4 (8.5%) included warnings related to their use in pediatric patients. Of the 270 oral liquid medications reviewed, 206 (76.3%) contained at least 1 -potentially inappropriate excipient. Of the 20 commonly used IV medications, 3 (15%) contained at least 1 potentially inappropriate excipient. CONCLUSIONS: This review found that many medications listed in the KIDs List are included in our -institution's formulary and that few have warnings for pediatric patients built into the institutional electronic health record. Further review of medications in the formulary will be conducted to determine the next steps to implementing KIDs List recommendations.

ABSTRACT

BACKGROUND: Interventions to improve racial equity in access to living donor kidney transplants (LDKT) have focused primarily on patients, ignoring the contributions of clinicians, transplant centers, and health system factors. Obtaining access to LDKT is a complex, multi-step process involving patients, their families, clinicians, and health system functions. An implementation science framework can help elucidate multi-level barriers to achieving racial equity in LDKT and guide the implementation of interventions targeted at all levels. METHODS: We adopted the Pragmatic Robust Implementation and Sustainability Model (PRISM), an implementation science framework for racial equity in LDKT. The purpose was to provide a guide for assessment, inform intervention design, and support planning for the implementation of interventions. RESULTS: We applied 4 main PRISM domains to racial equity in LDKT: Organizational Characteristics, Program Components, External Environment, and Patient Characteristics. We specified elements within each domain that consider perspectives of the health system, transplant center, clinical staff, and patients. CONCLUSION: The applied PRISM framework provides a foundation for the examination of multi-level influences across the entirety of LDKT care. Researchers, quality improvement staff, and clinicians can use the applied PRISM framework to guide the assessment of inequities, support collaborative intervention development, monitor intervention implementation, and inform resource allocation to improve equity in access to LDKT.

ABSTRACT

This study examined different sources of emotion socialization. Children (N = 256, 115 girls, 129 boys, 12 child gender not reported) and parents (62% White, 9% Black, 19% Hispanic, 3% Asian American, and 7% "Other") were recruited from Denver, Colorado. In waves 1 (Mage = 2.45 years, SD = 0.26) and 2 (Mage = 3.51 years, SD = 0.26), parents and children discussed wordless images of children experiencing an emotion (e.g., sad after dropping ice cream). Children's emotion knowledge was assessed at waves 2 and 3 (Mage = 4.48 years, SD = 0.26). Structural equation modeling found concurrent and prospective relations between parents' questions, parents' emotion talk, children's emotion talk, and children's emotion knowledge, highlighting the multidimensional nature of early emotion socialization.

ABSTRACT

Efficient treatment of acute myeloid leukemia (AML) patients remains a challenge despite recent therapeutic advances. Here, using a CRISPRi screen targeting chromatin factors, we identified the nucleosome-remodeling factor (NURF) subunit BPTF as an essential regulator of AML cell survival. We demonstrate that BPTF forms an alternative NURF chromatin remodeling complex with SMARCA5 and BAP18, which regulates the accessibility of a large set of insulator regions in leukemic cells. This ensures efficient CTCF binding and boundary formation between topologically associated domains that is essential for maintaining the leukemic transcriptional programs. We also demonstrate that the well-studied PHD2-BROMO chromatin reader domains of BPTF, while contributing to complex recruitment to chromatin, are dispensable for leukemic cell growth. Taken together, our results uncover how the alternative NURF complex contributes to leukemia and provide a rationale for its targeting in AML.

ABSTRACT

Parents play an important role in socializing children's emotion understanding. Previous research shows that parents emphasize different aspects of emotion contexts depending on the discrete emotion. However, there is limited research on how parents and children discuss self-conscious emotions, such as embarrassment, guilt, and shame, and what socialization practices parents employ to elicit children's talk about these emotions. In this study, children (N = 166, 78 females, 88 males) ages 2-3 years (M = 2.46, SD = 0.26) and their parents (65.5% White, 10.2% Black, 17.5% Hispanic, 2.4% Asian American, and 5.4% other) from a large city in the Western United States discussed a wordless storybook depicting different female and male characters experiencing self-conscious emotions (embarrassment, guilt, shame, awe, and pride). Parents' and children's emotion talk and parents' questions were coded from their conversations about each emotion scenario and subsequently analyzed by discrete emotion, child gender, and the depicted character's gender. Parents and children differentially focused on different aspects of each self-conscious emotion as a function of discrete emotion and picture gender, and elements of children's talk about self-conscious emotions were related to children's expressive language and age. Additionally, parents' emotion talk and questions about emotions were directly related to children's emotion talk, even after controlling for children's age, expressive language, and parental education. Taken together, these findings suggest that parent-child emotion conversations may be one context that facilitates the development of children's understanding of self-conscious emotions.

ABSTRACT

Vascular cognitive impairment (VCI) is a lifelong process encompassing a broad spectrum of cognitive disorders, ranging from subtle or mild deficits to prodromal and fully developed dementia, originating from cerebrovascular lesions such as large and small vessel disease. Genetic predisposition and environmental exposure to risk factors such as unhealthy lifestyles, hypertension, cardiovascular disease, and metabolic disorders will synergistically interact, yielding biochemical and structural brain changes, ultimately culminating in VCI. However, little is known about the pathological processes underlying VCI and the temporal dynamics between risk factors and disease mechanisms (biochemical and structural brain changes). This narrative review aims to provide an evidence-based summary of the link between individual vascular risk/disorders and cognitive dysfunction and the potential structural and biochemical pathophysiological processes. We also discuss some key challenges for future research on VCI. There is a need to shift from individual risk factors/disorders to comorbid vascular burden, identifying and integrating imaging and fluid biomarkers, implementing a life-course approach, considering possible neuroprotective influences of positive life exposures, and addressing biological sex at birth and gender differences. Finally, this review highlights the need for future researchers to leverage and integrate multidimensional data to advance our understanding of the mechanisms and pathophysiology of VCI.

ABSTRACT

Introduction: HIV pre-exposure prophylaxis (PrEP) is largely underutilized in the Southern United States. Given their community presence, pharmacists are well positioned to provide PrEP within rural, Southern regions. However, pharmacists' readiness to prescribe PrEP in these communities remains unknown. Objective: To determine the perceived feasibility and acceptability of prescribing PrEP by pharmacists in South Carolina (SC). Methods: We distributed a 43-question online descriptive survey through the University of SC Kennedy Pharmacy Innovation Center's listerv of licensed SC pharmacists. We assessed pharmacists' comfort, knowledge, and readiness to provide PrEP. Results: A total of 150 pharmacists responded to the survey. The majority were White (73%, n=110), female (62%, n=93), and non-Hispanic (83%, n=125). Pharmacists practiced in retail (25%, n=37), hospital (22%, n=33), independent (17%, n=25), community (13%, n=19), specialty (6%, n=9), and academic settings (3%, n=4); 11% (n=17) practiced in rural locales. Pharmacists viewed PrEP as both effective (97%, n=122/125) and beneficial (74% n=97/131) for their clients. Many pharmacists reported being ready (60% n=79/130) and willing (86% n=111/129) to prescribe PrEP, although over half (62% n=73/118) cited lack of PrEP knowledge as a barrier. Pharmacists described pharmacies as an appropriate location to prescribe PrEP (72% n=97/134). Conclusions: Most SC pharmacists surveyed considered PrEP to be effective and beneficial for individuals who frequent their pharmacy and are willing to prescribe this therapy if statewide statutes allow. Many felt that pharmacies are an appropriate location to prescribe PrEP but lack a complete understanding of required protocols to manage these patients. Further investigation into facilitators and barriers of pharmacy-driven PrEP are needed to enhance utilization within communities.

ABSTRACT

BACKGROUND: Nonmedical opioid use (NMOU) has been associated with opioid overdose deaths. This pattern of misuse can be seen in those using opioids for cancer-associated pain. We present a case that highlights the complexities associated with NMOU and a patient's care at the end of life. CASES DESCRIPTION: A patient with a metastatic solid tumor malignancy along with co-occurring history of polysubstance abuse was admitted to an acute palliative and supportive care unit (APSCU). The patient demonstrated behaviors concerning for NMOU during her hospital stay but had increased symptom expression concerning for worsening dyspnea while in the APSCU. Unfortunately, she used home opioids, which was unknown to the team at the time along with requesting for higher doses of opioids that were being prescribed. This caused a worsening respiratory status and affected her care. Using an interdisciplinary approach, the providers managed her symptoms and discharged her safely to see her child. CONCLUSION: This highlights the complexities of the alleviation of suffering in those with NMOU. It is important to continue to manage NMOU at the end of life due to its effects on quality of life. A multimodal approach is recommended to identify and care for these patients.

ABSTRACT

BACKGROUND: Underutilization of HIV pre-exposure prophylaxis (PrEP) in the Southern United States (US) is well-documented. Urgent care (UC) centers are positioned as communityfacing access points to PrEP, but the feasibility of integrating PrEP services into this setting is unclear. We conducted a survey of UC clinicians in the Southern US to better understand their perceptions of the feasibility of providing PrEP in their practice setting. OBJECTIVE: The study aims to determine the feasibility and acceptability of providing PrEP services in the UC setting through a cross-sectional survey of UC clinicians. METHODS: We conducted a 48-item cross-sectional survey of UC clinicians in the Southern US, between July and September 2020. The survey was distributed through the Urgent Care Association (UCA) and American Academy of Urgent Care Medicine (AAUCM) professional listservs as well as directly to publicly listed e-mail addresses. RESULTS: Eighty-two clinicians responded to the survey. Most clinicians had familiarity with PrEP (97%). All respondents rated PrEP as an effective way to prevent HIV. However, less than half felt UC facilities were an appropriate place to prescribe PrEP. Few respondents (8%) expressed doubts that expansion of PrEP access would decrease the incidence of HIV in their community. CONCLUSION: These findings show UC clinicians are familiar with PrEP, and many believe it would benefit their patients; however, provider opinions on the appropriateness of providing PrEP in the UC setting differ. Further studies on PrEP implementation in UC centers are needed.

ABSTRACT

Modeling is a scientific practice that supports creative reasoning, motivates inquiry, and facilitates community sense-making. This paper explores students' perspectives on modeling in an undergraduate laboratory course, Authentic Inquiry through Modeling (AIM-Bio), in which they proposed, tested, and revised their own models. We conducted comparative case studies of eight students over a semester. Students described using models to support multiple forms of scientific reasoning and hypothesis generation. They recounted the challenges of dealing with uncertainty and integrating diverse ideas. They also described how these challenges pushed their thinking. Overall, students reported feeling a sense of scientific authenticity and agency through their modeling experience. We additionally provide an in-depth look at two students whose unique experiences in AIM-Bio emphasize the variable ways modeling can support inquiry learning. We claim that modeling emerged as a legitimate practice among students, because the AIM-Bio curriculum encouraged diversity in students' models, provided opportunities for students to grapple with uncertainty, and fostered collaboration between students. We suggest that biology educators consider how model-based inquiry can allow students to participate in science, as a way to support interest in, identification with, and ultimately persistence in science, technology, engineering, and mathematics fields.

ABSTRACT

BACKGROUND: Standard diagnostic criteria are not useful for identifying bloodstream infection in patients with an acute burn injury patients. The study objective was to develop and validate a tool using common laboratory, clinical, and patient parameters for early identification of bloodstream infection after acute burn injury (within 10 days after a burn). METHODS: We retrospectively and prospectively reviewed for tool development the hospital course of patients with an acute burn injury (n = 156) and validated the tool in different cohorts (retrospective [n = 26] and prospective [n = 90]). The Pearson correlation identified independent variables associated with bloodstream infection (P < .1) in the development cohort that were then analyzed using binary logistic regression to identify the simplest model (P < .05; adjusted odds ratio >1). Classification and regression tree analysis was used to identify tool parameter breakpoints. Performance metrics were completed to evaluate and validate the tool. RESULTS: The best model (P < .05) was: Ln [odds of bloodstream infection] = -96.749 + 3.230 (platelet volatility) + 2.235 (max temperature [°C]) + 0.339 (% full burn) + 0.242 (% partial burn) + 0.045 (max heart rate [bpm]), with a threshold probability categorizing bloodstream infection of >48%. The sensitivity, specificity, accuracy, false positive rate, false negative rate, and positive (+) and negative (-) likelihood ratios of the tool in the developmental cohort (n = 156) were 89%, 98%, 96%, 2%, 11%, 53, and 0·11, respectively; and in the prospective validation cohort (n = 90 were 91%, 90%, 90%, 10%, 9%, 9, and 0·1, respectively (n = 90). CONCLUSION: The validated bloodstream infection screening tool in patients with acute burn injury has excellent predictive ability to assist in the identification of patients for whom blood cultures should be requested.

ABSTRACT

AIM/PURPOSE: This integrative review addresses whether the presence and timing of advanced care planning (ACP) with or without a palliative care (PC) consultation affect place of death and use of high-intensity medical care at end-of-life (EOL) in adolescent and young adult and adult cancer patients receiving hematopoietic stem cell transplant (HSCT) therapy. METHODS AND RESULTS: A literature search was completed in the Scopus and PubMed databases. The search was not restricted by date but was restricted to English language. A total of 1,616 articles were found, and after exclusion of duplicates and irrelevance, 79 articles were available to review. After reviewing inclusion and exclusion criteria, 9 articles related to ACP with HSCT were found, and 4 were eliminated after further review, resulting in 5 viable articles for review related to EOL outcomes. EOL outcomes reviewed were place of death and high-intensity medical care. Factors noted to influence these measures included the presence or absence of ACP, the timing of ACP, and PC consultation. Overall survival also emerged as an EOL outcome affected by ACP. CONCLUSION: Although there have been many barriers identified to ACP discussions in the HSCT population, the findings from the integrative literature review support the use of early ACP with patients who have hematologic malignancies undergoing HSCT to address patient EOL goals and reduce healthcare utilization at the EOL. The data also suggest that identification of patients who would most benefit from early engagement in ACP may positively impact outcomes.

ABSTRACT

BACKGROUND: There are known gender differences in the impacts infertility has on quality of life and well-being. Less is known about how infertile couples spend time on fertility-related tasks and associations with quality of life. The purpose of this study is to evaluate whether time spent on tasks related to family-building decision-making (including research, reflection, discussions with partner, discussions with others, and logistics) were associated with fertility-specific quality of life or anxiety among new patients. METHODS: Couples or individuals (N = 156) with upcoming initial consultations with a reproductive specialist completed the Fertility Quality of Life (FertiQoL) tool, which produces a Core (total) score and four subscales: Emotional, Relational, Social, and Mind-Body. We developed questions to measure time spent in the previous 24 h on tasks related to family-building. We tested for differences by gender in time use (McNemar's Test) and used ordinary least squares regression to analyze the relationship between time use and FertiQoL scores. RESULTS: In the week before a new consultation, a higher percentage of women reported time spent in the past 24 h in research, reflecting, discussion with others, and logistics compared to male partners (all p < 0.05). In adjusted models, more time spent reflecting was associated with worse FertiQoL scores for both men and women, as well as with higher anxiety for men. Time spent in discussion with others was associated with higher anxiety for women but better Social FertiQoL scores for men. CONCLUSIONS: Couples seeking infertility consultation with a specialist reported spending time on tasks related to family-building before the initial visit. There were gender differences in the amount of time spent on these tasks, and time was associated with fertility-specific quality of life and anxiety.

ABSTRACT

BACKGROUND: Patient-centered care is a pillar of quality health care and is important to patients experiencing infertility. In this study we used empirical, in-depth data on couples' experiences of infertility treatment decision making to inform and revise a conceptual framework for patient-centered fertility treatment that was developed based on health care professionals' conceptualizations of fertility treatment, covering effectiveness, burden, safety, and costs. METHODS: In this prospective, longitudinal mixed methods study, we collected data from both members (separately) of 37 couples who scheduled an initial consult with a reproductive specialist. Data collection occurred 1 week before the initial consultation, 1 week after the initial consultation, and then roughly 2, 4, 8, and 12 months later. Data collection included semi-structured qualitative interviews, self-reported questionnaires, and medical record review. Interviews were recorded, transcribed, and content analyzed in NVivo. A single coder analyzed all transcripts, with > 25% of transcripts coded by a second coder to ensure quality control and consistency. RESULTS: Content analysis of the interview transcripts revealed 6 treatment dimensions: effectiveness, physical and emotional burden, time, cost, potential risks, and genetic parentage. Thus, the revised framework for patient-centered fertility treatment retains much from the original framework, with modification to one dimension (from safety to potential risks) and the addition of two dimensions (time and genetic parentage). For patients and their partners making fertility treatment decisions, tradeoffs are explicitly considered across dimensions as opposed to each dimension being considered on its own. CONCLUSIONS: Patient-centered fertility treatment should account for the dimensions of treatment that patients and their partners weigh when making decisions about how to add a child to their family. Based on the lived experiences of couples seeking specialist medical care for infertility, this revised conceptual framework can be used to inform patient-centered treatment and research on infertility and to develop decision support tools for patients and providers.

ABSTRACT

BACKGROUND: Infertility treatment decisions require people to balance multiple priorities. Within couples, partners must also negotiate priorities with one another. In this study, we assessed the family-building priorities of couples prior to their first consultations with a reproductive specialist. METHODS: Participants were couples who had upcoming first consultations with a reproductive specialist (N = 59 couples (59 women; 59 men)). Prior to the consultation, couples separately completed the Family-Building Priorities Tool, which tasked them with ranking from least to most important 10 factors associated with family building. We describe the highest (top three) and lowest (bottom three) priorities, the alignment of priorities within couples, and test for differences in prioritization between men and women within couples (Wilcoxon signed rank test). RESULTS: Maintaining a close and satisfying relationship with one's partner was ranked as a high priority by majorities of men and women, and in 25% of couples, both partners ranked this factor as their most important priority for family building. Majorities of men and women also ranked building a family in a way that does not make infertility obvious to others as a low priority, and in 27% of couples, both partners ranked this factor as the least important priority for family building. There were also differences within couples that involved either men or women ranking a particular goal more highly than their partners. More women ranked two factors higher than did their partners: 1) that I become a parent one way or another (p = 0.015) and 2) that I have a child in the next year or two (p < 0.001), whereas more men ranked 4 factors higher than their partners: 1) that our child has [woman's] genes (p = 0.025), 2) that our child has [man's] genes (p < 0.001), 3) that I maintain a close relationship with my partner (p = 0.034), and 4) that I avoid side effects from treatment (p < 0.001). CONCLUSIONS: Clinicians who support patients in assessing available family-building paths should be aware that: (1) patients balance multiple priorities as a part of, or beside, becoming a parent; and (2) patients and their partners may not be aligned in their prioritization of achieving parenthood. For infertility patients who are in relationships, clinicians should encourage the active participation of both partners as well as frank discussions about each partner's priorities for building their family.

ABSTRACT

Storms cause a substantial increase in the fecal indicator bacteria (FIB) concentrations in stream water as a result of FIB-laden runoff and the release of FIB from stream sediments. Previous work has emphasized the association between FIB and bed sediments finer than sand. The objectives of this work were to elucidate the effect of various velocities on the entrainment of bed-dwelling coliforms in sand-bed streams and to refine methodologies for quantifying sandy streambeds as sources of FIB. Pump-induced hydrographs were created using a stainless steel nonrecirculating flume. Experiments consisted of simulating four storm hydrographs and collecting water samples upstream and downstream of a sand bed at selected intervals. Bed sediment samples were collected before and after each event. The highest concentrations of total coliform and suspended sediments generally occurred in the downstream samples during the rising limb of the hydrographs as a result of entrainment of coliforms and sand from the bed to the water column. There was a first flush effect in the system, as the upper layer of sand was influenced by a rapidly increasing velocity at ∼0.2 m s. Coliforms downstream of the sand bed increased rapidly as velocity exceeded this threshold but then declined even as velocity and discharge continued to increase. This likely reflects the depletion of coliforms as the more densely populated sediment layer was flushed out. There is evidence that streams with sand beds harbor enough FIB that development of total maximum daily loads (TMDLs) should include consideration of them as a source.

ABSTRACT

Certificates of Confidentiality, issued by agencies of the U.S. government, are regarded as an important tool for meeting ethical and legal obligations to safeguard research participants' privacy and confidentiality. By shielding against forced disclosure of identifying data, Certificates are intended to facilitate research on sensitive topics critical to the public's health. Although Certificates are potentially applicable to an extensive array of research, their full legal effect is unclear, and little is known about stakeholders' views of the protections they provide. To begin addressing this challenge, we conducted a national survey of institutional review board (IRB) chairs, followed by telephone interviews with selected chairs, to learn more about their familiarity with and opinions about Certificates; their institutions' use of Certificates; policies and practices concerning when Certificates are required or recommended; and the role Certificates play in assessments of research risk. Overall, our results suggest uncertainty about Certificates among IRB chairs. On most objective knowledge questions, most respondents chose the incorrect answer or 'unsure'. Among chairs who reported more familiarity with Certificates, composite opinion scores calculated based on five survey questions were evenly distributed among positive, neutral/middle, and negative views. Further, respondents expressed a variety of ideas about the appropriate use of Certificates, what they are intended to protect, and their effect on research risk. Nevertheless, chairs who participated in our study commonly viewed Certificates as a potentially valuable tool, frequently describing them as an 'extra layer' of protection. These findings lead to several practical observations concerning the need for more stakeholder education about Certificates, consideration of Certificates for a broader range of studies, the importance of remaining vigilant and using all tools available to protect participants' confidentiality, and the need for further empirical investigation of Certificates' effect on researchers and research participants.

ABSTRACT

OBJECTIVE: To describe obstetrician-gynecologists' (ob-gyns') views and willingness to help women seeking abortion in a variety of clinical scenarios. METHODS: We conducted a mailed survey of 1,800 U.S. ob-gyns. We presented seven scenarios in which patients sought abortions. For each, respondents indicated if they morally objected to abortion and if they would help patients obtain an abortion. We analyzed predictors of objection and assistance. RESULTS: The response rate was 66%. Objection to abortion ranged from 16% (cardiopulmonary disease) to 82% (sex selection); willingness to assist ranged from 64% (sex selection) to 93% (cardiopulmonary disease). Excluding sex selection, objection was less likely among ob-gyns who were female (odds ratio [OR] 0.5, 95% confidence interval [CI] 0.4-0.8), urban (OR 0.3, 95% CI 0.1-0.7), or Jewish (OR 0.3, 95% CI 0.1-0.7) compared with male, rural, or religiously unaffiliated ob-gyns. Objection was more likely among ob-gyns from the South (OR 1.9, 95% CI 1.2-3.0) or Midwest (OR 1.9, 95% CI 1.2-3.1), and among Catholic, Evangelical Protestant, or Muslim ob-gyns, or those for whom religion was most important, compared with reference. Among ob-gyns who objected to abortion in a given case, approximately two-thirds would help patients obtain an abortion. Excluding sex selection, assistance despite objection was more likely among female (OR 1.8, 95% CI 1.1-2.9) and United States-born ob-gyns (OR 2.2, 95% CI 1.1-4.7) and less likely among southern ob-gyns (OR 0.3, 95% CI 0.2-0.6) or those for whom religion was most important (OR 0.3, 95% CI 0.1-0.7). CONCLUSION: Most ob-gyns help patients obtain an abortion even when they morally object to abortion in that case. Willingness to assist varies by clinical context and physician characteristics. LEVEL OF EVIDENCE: II.

ABSTRACT

The Attitudes to Deafness Scale is a 22-item measure of attitudes toward people who are deaf designed for use with human service professionals. Attitude statements were generated from personal accounts by deaf people in the literature and from a focus group in which deaf people discussed their experience of hearing people's attitudes toward them. A 60-item scale was administered to a group of 121 clinical and forensic psychologists during their training. Item analysis was conducted to select items that effectively distinguished participants with a positive attitude from those with a negative attitude toward deaf people. The scale may be used in any context where a professional group comes into contact with people who are deaf.
