RESUMEN

BACKGROUND: A standardized approach to prepare trainees for the job search has not been described. The objective of this study was to describe and evaluate an educational series on the job search for Neonatal-Perinatal Medicine (NPM) fellows and identify participants' job search knowledge gaps. METHODS: During the 2020-2021 academic year, we created a virtual, seven-part job search series for NPM fellows that required no funding. The series has been repeated annually. We use REDCap surveys to register participants, collect baseline/demographic information, and evaluate the series' impact at the beginning and end of the job search timeline. RESULTS: In the 2021-2022 academic year, 290 individuals registered for the series, and 89% completed the baseline/demographic survey. The majority were NPM fellows (89%). Early career neonatologists, NPM hospitalists, and pediatric residents also utilized the series (11%). Less than 25% reported being "knowledgeable" or "very knowledgeable" of core job search components, including the timeline of the job search, contract negotiation, and the general roles and responsibilities of junior faculty. Of those who completed the final job search survey and underwent a job search (60%, 97 of 162), the majority (86%) felt that career planning during training was stressful and believed that job search preparation should be structured into the NPM fellowship curriculum (81%). Many felt that the Job Search Series was helpful in elucidating components of the job search. CONCLUSIONS: We identified several knowledge gaps in NPM fellows' understanding of how to find, prepare for, and negotiate their first post-training job. We strongly believe these knowledge gaps are not unique to NPM fellows and that all graduate medical education trainees would benefit from a similar, easy-to-implement, no-cost series.

RESUMEN

OBJECTIVE: To determine the frequency, degree, and nature of prognostic discordance between parents and physicians caring for infants with neurologic conditions. STUDY DESIGN: In this observational cohort study, we enrolled parents and physicians caring for infants with neurologic conditions in advance of a family conference. Parent-physician dyads completed a postconference survey targeting expected neurologic outcomes across 3 domains (motor, speech, and cognition) using a 6-point scale. Prognostic discordance was defined as a difference of ≥2 response options and was considered moderate (difference of 2-3 response options) or high (difference of 4-5 response options). Responses were categorized as differences in belief and/or differences in understanding using an existing paradigm. RESULTS: Forty parent-physician dyads of 28 infants completed surveys. Parent-physician discordance about prognosis occurred in ≥1 domain in the majority of dyads (n = 28/40, 70%). Discordance was generally moderate in degree (n = 23/28, 82%) and occurred with similar frequency across all domains. Of parent-physician dyads with discordance, the majority contained a difference in understanding in at least 1 domain (n = 25/28, 89%), while a minority contained a difference of belief (n = 6/28, 21%). When discordance was present, parents were typically more optimistic in their predictions compared with physicians (n = 25/28, 89%). CONCLUSIONS: Differing perceptions about the prognosis of critically ill infants are common and due to differences in both understanding and belief. These findings can be used to develop targeted interventions to improve prognostic communication.

RESUMEN

OBJECTIVE: We characterize the content and role of prognostic discussion for infants with neurologic conditions. METHODS: In this descriptive qualitative study, we prospectively enrolled infants (age < 1 year) in the intensive care unit with a neurologic condition anticipated to have ≥1 family conference about prognosis or goals of care. We audiorecorded family conferences as they occurred. We used a rapid-cycle qualitative approach to identify and refine themes. RESULTS: Forty infants and 61 parents were enrolled; 68 family conferences occurred for 24 infants. The majority of infant cases (n = 23/24, 96%) and conferences (n = 64/68, 94%) included discussion of neurologic prognosis. Common infant diagnoses included prematurity (n = 12, 52%), genetic conditions (n = 9, 35%), and brain malformations (n = 7, 30%). We identified 2 themes relating to the characterization of the infant's prognosis: (1) predictions of impairment and (2) rationale for prognostic predictions. We identified 3 themes characterizing the role of prognostic discussion: (1) aligning parent and clinician understanding of infant outcome, (2) influencing decision-making, and (3) preparing for life at home. We identified 2 themes characterizing discussion of prognostic uncertainty: (1) multilayered types of uncertainty and (2) holding space for hope alongside uncertainty. INTERPRETATION: In this cohort of infants with neurologic conditions and their parents, we identified salient themes characterizing the content and role of discussion about neurologic outcome. Our findings highlight that prognostic discussion focuses on anticipated impairments, informs decision-making, and helps families prepare for home life. Future work should characterize whether these findings align with parent preferences for prognostic disclosure. ANN NEUROL 2022;92:699-709.

RESUMEN

BACKGROUND: A positive urine fentanyl toxicology test may have considerable consequences for peripartum individuals, yet the extent to which fentanyl administration in a labor epidural may lead to such a positive test is poorly characterized. OBJECTIVE: This study aimed to quantify the extent to which neuraxial fentanyl in labor neuraxial analgesia can lead to a positive peripartum maternal or neonatal urine toxicology test. STUDY DESIGN: We performed a prospective cohort study of pregnant participants planning a vaginal delivery with neuraxial analgesia. Participants with a history of substance use disorder, hypertension, or renal or liver disease were excluded. A urine sample was collected before initiation of neuraxial analgesia, each time the bladder was emptied during labor, and up to 4 times postpartum. Neonatal urine was collected once. Urine fentanyl testing was performed using 2 common toxicology testing methods, namely immunoassay and liquid chromatography with tandem mass spectrometric detection. RESULTS: A total of 33 maternal-infant dyads yielded a total of 178 urine specimens. All maternal specimens were negative for fentanyl using liquid chromatography with tandem mass spectrometric analysis and immunoassay before initiation of neuraxial analgesia. Intrapartum, 26 of 30 (76.7%) participants had positive liquid chromatography with tandem mass spectrometry results for fentanyl or its metabolites, and 12 of 30 (40%) participants had positive immunoassay results. Postpartum, 19 of 21 (90.5%) participants had positive liquid chromatograph with tandem mass spectrometric results, and 13 of 21 (61.9%) had a positive immunoassay result. Of the 13 neonatal specimens collected, 10 (76.9%) were positive on liquid chromatography with tandem mass spectrometry analysis, the last of which remained positive 29 hours and 50 minutes after delivery. CONCLUSION: Neuraxial fentanyl for labor analgesia may lead to positive maternal and neonatal toxicology tests at various times after epidural initiation and cessation and at different rates depending on the testing method used. Caution should be used in interpreting toxicology test results of individuals who received neuraxial analgesia to avoid false assumptions about nonprescribed use.

RESUMEN

OBJECTIVE: Workforce characteristics and compensation specific to early career neonatologists remain poorly defined. Lack of transparency surrounding compensation limits benchmarking for neonatologists entering the workforce and may negatively influence individual lifetime earnings. Our objective was to provide granular data for this unique subpopulation by defining employment characteristics and factors influential to compensation of early career neonatologists. STUDY DESIGN: An anonymous 59-question cross-sectional electronic survey was distributed to eligible members of American Academy of Pediatrics Trainees and Early Career Neonatologists. A focused analysis was conducted on salary and bonus compensation data collected from the survey instrument. Respondents were classified based on primary site of employment: nonuniversity located (e.g., private practice, hospital employed, government/military, and hybrid employment groups) versus university located practice settings (e.g., work is primarily conducted in a neonatal intensive care unit (NICU) setting located within a university organization). Median quantile regression was used to conduct univariate and multivariate analyses using SAS Software version 9.4. RESULTS: We received 348 responses (26.7% response rate). Median salary was $220,000 (interquartile range: $200,000-250,000). Factors associated with salary include academic rank (instructor: $196,000; assistant professor: $220,000 [12% increase; p < 0.001]; associate professor: $260,000 [18% increase]; p = 0.027) and years of experience (p = 0.017), after adjusting for relevant factors. Employment location, practice type, group size, clinical schedule, location of medical school training, and gender identity did not significantly influence salary in multivariate quantile regression. Median annual bonus was $7,000 higher for nonuniversity located positions ($20,000 vs. 13,000; p = 0.021), with assumption of additional administrative roles and practice group seniority as most commonly cited bonus criteria (p = 0.002 and <0.001, respectively). CONCLUSION: Academic rank and years of experience may influence salary. Bonus earnings are higher for nonuniversity located positions. Employment models are evolving to incorporate academic teaching appointments while practicing in nonuniversity located NICUs. This is the first detailed compensation analysis of early career neonatologists. KEY POINTS: · Transparent compensation data specific to early career neonatologists is lacking.. · Associated factors influential to compensation of early career neonatologists remain unclear.. · This study identifies years of experience and academic rank as possible factors influencing salary earnings of early career neonatologists.. · Practicing in nonuniversity located positions was associated with greater bonus earning potential..

RESUMEN

OBJECTIVE: Transitioning into the early career physician workforce is a uniquely challenging period in a neonatologist's career. There are limited educational opportunities in fellowship regarding career progression, practice models, and benefits. Understanding these factors are key when searching for employment. This study evaluates the early career neonatologist (ECN) workforce and employment characteristics to improve identification of professional needs. STUDY DESIGN: An anonymous 59-question cross-sectional survey was distributed in July 2020 to members of the American Academy of Pediatrics Section on Neonatal Perinatal Medicine Trainees and Early Career Neonatologists (TECaN). The survey instrument was designed using SurveyMonkey and assessed search methods for identifying employers, employment contract details, and professional duties. Questions addressed clinical service time, level of acuity, protected research time, financial compensation, benefits, job search methods, and promotion requirements. Comparisons were drawn between respondents exclusively working in a university-based setting and respondents employed in nonuniversity locations. Responses were collected using SurveyMonkey and then extracted to a Microsoft Excel Workbook for analysis. Statistical analysis was performed using SAS version 9.4. RESULTS: Of 1,302 eligible members, 348 people responded (26.7%). Forty-six percent of respondents worked in a university setting and 54% worked in a nonuniversity setting. Using employment site as a discriminator, significant differences were noted in scheduling models. University-located respondents were more likely to work 2-week block schedules, fewer weekend/weeknight call, less clinical weeks per year, and more research/administrative weeks per year. Between university and nonuniversity located positions, benefits were largely comparable, while factors perceived as influential toward promotion varied depending on practice site. CONCLUSION: This study provides ECNs with a contemporary workforce description vital to graduating TECaN seeking employment or renegotiating professional obligations. While benefits were largely similar based on practice site, promotion factors and scheduling models may vary depending on location. KEY POINTS: · Data specific to informing employment decisions for graduating Trainees and Early Career Neonatologists are limited.. · This study provides benchmarks for evaluating employment opportunities presented to early career neonatologists.. · Practice site can influence promotion factors..

RESUMEN

AIMS/HYPOTHESIS: Despite recommendations to screen women with diabetes risk factors for hyperglycaemia in the first trimester, criteria for normal glucose values in early pregnancy have not been firmly established. We aimed to compare glucose levels in early pregnancy with those later in gestation and outside of pregnancy in women with diabetes risk factors. METHODS: In pregnant women (N = 123) followed longitudinally through the postpartum period, and a separate cohort of non-pregnant women (N = 65), we performed 75 g oral glucose tolerance tests. All participants had one or more risk factors for diabetes. Using linear regression, we tested for differences in glucose levels between non-pregnant and pregnant women at early (7-15 weeks) and mid-late (24-32 weeks) gestation as well as postpartum, with adjustment for maternal age, parity, marital status and BMI. In a longitudinal analysis using mixed-effects models, we tested for differences in glucose levels across early and mid-late pregnancy compared with postpartum. Differences are expressed as ß (95% CI). RESULTS: Fasting glucose was lower in pregnant compared with non-pregnant women by 0.34 (0.18, 0.51) mmol/l (p < 0.0001) in early pregnancy and by 0.45 (0.29, 0.61) mmol/l (p < 0.0001) in mid-late pregnancy. In longitudinal models, fasting glucose was lower by 0.13 (0.04, 0.21) mmol/l (p = 0.003) in early pregnancy and by 0.16 (0.08, 0.25) mmol/l (p = 0.0003) in mid-late pregnancy compared with the same women postpartum. Early pregnancy post-load glucose levels did not differ from those in non-pregnant women or the same women postpartum. In mid-late pregnancy, compared with non-pregnant women, elevations in 1 h post-load glucose level (0.60 [-0.12, 1.33] mmol/l, p = 0.10) and 2 h post-load glucose (0.49 [-0.21, 1.19] mmol/l, p = 0.17) were not statistically significant. However, in longitudinal analyses, 1 h and 2 h post-load glucose levels were higher in mid-late pregnancy (by 0.78 [0.35, 1.21] mmol/l, p = 0.0004, and 0.67 [0.30, 1.04] mmol/l, p = 0.0005, respectively) when compared with postpartum. CONCLUSIONS/INTERPRETATION: In women with diabetes risk factors, fasting glucose declines in the first trimester. Post-load glucose increases later in pregnancy. These findings may inform criteria for diagnosing hyperglycaemia early in pregnancy.

RESUMEN

OBJECTIVE: Fetal growth restriction (FGR) is associated with poor neonatal outcomes and stillbirth, and screening via fundal height or ultrasound is routinely performed. During the novel coronavirus disease 2019 (COVID-19) pandemic, we developed a hybrid model of prenatal care which decreased the frequency of in-person visits and incorporated telemedicine visits. We sought to determine if prenatal FGR diagnoses decreased with this hybrid model compared with routine prenatal care. STUDY DESIGN: This was a retrospective cohort study of singleton nonanomalous neonates with birth weights <10th percentile at term. The "routine care" group was consisted of those who born between April and July 2019 with in-person prenatal care, and the "hybrid care" group was consisted of those who born between April and July 2020 with both in-person and telemedicine prenatal cares at a collaborative academic practice. The primary outcome was the rate of diagnosis of small for gestational age (SGA) as defined as infant birth weight <10th percentile without a prenatal diagnosis of FGR. The secondary outcome was timing of diagnosis of FGR. RESULTS: Overall, 1,345 and 1,296 women gave birth in the routine and hybrid groups, respectively. The number of in-person prenatal care visits decreased from 15,024 in the routine period to 7,727 in the hybrid period; 3,265 telemedicine visits occurred during the hybrid period. The total number of prenatal patients remained relatively stable at 3,993 and 3,753 between periods. Third trimester ultrasounds decreased from 2,929 to 2,014 between periods. Birth weights <10 percentile occurred in 115 (8.6%) births during the routine period and 79 (6.1%) births during the hybrid period. Of 115, 44 (38.3%) cases were prenatally diagnosed with FGR in the routine versus 28 of 79 (35.4%) in the hybrid group (p = 0.76). Median gestational age at diagnosis did not vary between groups (36 vs. 37 weeks, p = 0.44). CONCLUSION: A hybrid prenatal care model did not alter the detection of FGR. Future efforts should further explore the benefits of incorporating telemedicine into prenatal care. KEY POINTS: · Telemedicine visits can provide comprehensive prenatal care.. · FGR was diagnosed equally with hybrid versus routine prenatal care.. · FGR diagnosis was not delayed with hybrid care..

RESUMEN

Eleven organophosphate esters (OPEs) were detected in surface water and sediment samples from yearly sampling (2013-2018) in the Canadian Arctic. In water samples, ∑chlorinated-OPEs (Cl-OPEs) concentrations exceeded ∑non-chlorinated-OPEs (non-Cl-OPEs) with median concentrations of 10 ng L-1 and 1.3 ng L-1, respectively. In sediment samples, ∑Cl-OPEs and ∑nonchlorinated-OPEs had median concentrations of 4.5 and 2.5 ng g-1, respectively. High concentrations of OPEs in samples from the Mackenzie River plume suggest riverine discharge as an OPE source to the Canadian Arctic. The prevalence of OPEs at other sites is consistent with long-range transport. The OPE inventory of the Canadian Arctic Ocean representative of years 2013-2018 was estimated at 450-16,000 tonnes with a median ∑11OPE mass of 4100 tonnes with >99% of the OPE inventory estimated to be in the water column. These results highlight the importance of OPEs as water-based Arctic contaminants subject to long-range transport and local sources. The high OPE inventory in the water column of the Canadian Arctic Ocean points to the need for international regulatory mechanisms for persistent and mobile organic contaminants (PMOCs) that are not covered by the risk assessment criteria of the Stockholm Convention.

RESUMEN

BACKGROUND: Studies have demonstrated an association between phthalate exposure and childhood asthma, although results have been inconsistent. No epidemiological studies have examined exposure during the first year of life. OBJECTIVE: To investigate the association between phthalate exposures in the home environment during the first year of life, and subsequent development of childhood asthma and related symptoms. METHODS: This study used a case-cohort design including 436 randomly selected children and all additional cases of asthma at 5 years (ntotal = 129) and recurrent wheeze between 2 and 5 years (ntotal = 332) within the CHILD Cohort Study, a general population Canadian birth cohort of 3455 children. Phthalate exposure was assessed using house dust samples collected during a standardized home visit when children were 3-4 months of age. All children were assessed by specialist clinicians for asthma and allergy at 1, 3 and 5 years. Logistic regression was used to assess the association between exposure to five phthalates and asthma diagnosis at 5 years, and recurrent wheeze between 2 and 5 years, with further stratification by wheeze subtypes (late onset, persistent, transient) based on the timing of onset and persistence of wheeze symptoms. RESULTS: Di(2-ethylhexyl) phthalate (DEHP) had the highest concentration in dust (mediansubcohort = 217 µg/g), followed by benzyl butyl phthalate (BzBP) (20 µg/g). A nearly four-fold increase in risk of developing asthma was associated with the highest concentration quartile of DEHP (OR = 3.92, 95% CI: 1.87-8.24) including a positive dose-response relationship. A two-fold increase in risk of recurrent wheeze was observed across all quartiles compared to the lowest quartile of DEHP concentrations. Compared to other wheeze subtypes, stronger associations for DEHP were observed with the late onset wheezing subtype, while stronger associations for di-iso-butyl phthalate (DiBP) and BzBP were observed with the transient subtype. DISCUSSION: DEHP exposure at 3-4 months, at concentrations lower than other studies that reported an association, were associated with increased risks of asthma and recurrent wheeze among children at 5 years. These findings suggest the need to assess whether more stringent regulations are required to protect children's health, which can be informed by future work exploring the main sources of DEHP exposure.

RESUMEN

OBJECTIVE: To test the hypothesis that high fetal fraction (FF) on first trimester cell-free deoxyribonucleic acid (cfDNA) aneuploidy screening is associated with adverse perinatal outcomes. STUDY DESIGN: This is a single-institution retrospective cohort study of women who underwent cfDNA screening at <14 weeks' gestation and delivered a singleton infant between July 2016 and June 2018. Women with abnormal results were excluded. Women with high FF (≥95th percentile) were compared with women with normal FF (5th-95th percentiles). Outcomes investigated were preterm birth, small for gestational age, and hypertensive disorders of pregnancy. RESULTS: A total of 2,033 women met inclusion criteria. The mean FF was 10.0%, and FF >16.5% was considered high (n = 102). Women with high FF had a greater chance of delivering a small for gestational age infant

RESUMEN

OBJECTIVE: To determine the association between low fetal fraction and birth weight among women with a negative cell-free DNA (cfDNA) result for common aneuploidies in the first trimester. STUDY DESIGN: This is a retrospective cohort of women who delivered a singleton between July 2016 and June 2018 at a single institution and had normal cfDNA testing in the first trimester. The primary variable of interest was "low fetal fraction," which was defined as fetal fractions less than 5th percentile among all fetal fractions in the cohort (fetal fraction < 5.34%). The primary outcomes were birth weight ≤ 5th and ≤ 10th percentiles. Multivariable logistic regressions assessed for the association between low fetal fraction and birth weight. RESULTS: A total of 7,478 women delivered a singleton at ≥24 weeks' gestation, of which 2,387 (32%) underwent genetic screening through cfDNA; the majority were in the first trimester (n = 2,052 [86%]). 2,035 met the inclusion criteria. Birth weight ≤ 5th percentile was significantly higher in the low fetal fraction group (6.9 vs. 3.2%; p = 0.04). A low fetal fraction was associated with higher odds of an infant with a low birth weight: adjusted odds ratio (aOR) of 2.32 (95% CI 1.15-4.67) for birth weight ≤ 10th percentile (p = 0.02) and aOR of 3.73 (95% CI 1.40-9.03) for birth weight ≤ 5th percentile (p = 0.004). CONCLUSION: Low fetal fractions of ≤ 5th percentile were associated with an increased risk of birth weights ≤ 5th and ≤ 10th percentiles in women with negative cfDNA screening in the first trimester. Future work is needed to further investigate this relationship and to determine the potential clinical implications, such as third-trimester screening for growth restriction in women with low fetal fractions and negative cfDNA screening results.

RESUMEN

BACKGROUND: Mutant Ras oncogenes produce proteins that are unique to cancer cells and represent attractive targets for vaccine therapy. We have shown previously that vaccinating cancer patients with mutant ras peptides is feasible and capable of inducing a specific immune response against the relevant mutant proteins. Here, we tested the mutant ras peptide vaccine administered in combination with low dose interleukin-2 (IL-2) or/and granulocyte-macrophage colony-stimulating factor (GM-CSF) in order to enhance the vaccine immune response. METHODS: 5000 µg of the corresponding mutant ras peptide was given subcutaneously (SQ) along with IL-2 (Arm A), GM-CSF (Arm B) or both (Arm C). IL-2 was given SQ at 6.0 million IU/m²/day starting at day 5, 5 days/week for 2 weeks. GM-CSF was given SQ in a dose of 100 µg/day one day prior to each ras peptide vaccination for 4 days. Vaccines were repeated every 5 weeks on arm A and C, and every 4 weeks on arm B, for a maximum of 15 cycles or until disease progression. RESULTS: We treated 53 advanced cancer patients (38 with colorectal, 11 with pancreatic, 1 with common bile duct and 3 with lung) on 3 different arms (16 on arm A, 18 on arm B, and 19 on arm C). The median progression free survival (PFS) and overall survival (OS) was 3.6 and 16.9 months, respectively, for all patients evaluable for clinical response (n = 48). There was no difference in PFS or OS between the three arms (P = 0.73 and 0.99, respectively). Most adverse events were grade 1-2 toxicities and resolved spontaneously. The vaccine induced an immune response to the relevant ras peptide in a total of 20 out of 37 evaluable patients (54%) by ELISPOT, proliferative assay, or both. While 92.3% of patients on arm B had a positive immune response, only 31% of patients on arm A and 36% of patients on arm C had positive immune responses (P = 0.003, Fisher's exact test). CONCLUSIONS: The reported data showed that IL-2 might have a negative effect on the specific immune response induced by the relevant mutant ras vaccine in patients with advanced cancer. This observation deserves further investigations. TRIAL REGISTRATION: NCI97C0141.

RESUMEN

BACKGROUND: The protein products of the early genes E6 and E7 in high-risk HPV types 16 and 18 have been implicated in the oncogenic capability of these viruses. Therefore, these peptides represent attractive vaccine therapy targets. METHODS: Thirty-two patients with advanced cervical cancer (HPV16 or 18 positive) were treated with HPV16 E6 (18-26) (Arm A) or HPV16 E7 (12-20) peptide (Arm B) pulsed on PBMCs in order to illicit immune response against the relevant peptide on both arms. These PBMCs were cultured for a short time (48 hours only) and in the presence of GM- CSF, accordingly, they were identified as "Pre-Immature Dentritic Cells". RESULTS: 51Cr release assay and ELISPOT demonstrated evidence of specific immune response against the relevant peptide in 10/16 (63%) evaluable patients in arm A and 7/12 (58%) in arm B. HPV16 E6 was found to be homologous to HPV18 E6 in both vivo and vitro. The median overall survival (OS) and progression free survival (PFS) for the full cohort was 10.0 and 3.5 months, respectively. There were no RECIST responses in any patient. The majority of toxicities were grade I and II. CONCLUSIONS: We demonstrated the feasibility and ability of Pre-Immature Dentritic Cells pulsed with HPV16 E6 (18-26) or HPV16 E7 (12-20) to induce a specific immune response against the relevant peptide despite the advanced disease of the cervical cancer patients treated on this trial. We believe that this observation deserves further investigations.

RESUMEN

BACKGROUND: Effective learning strategies are crucial to the development of academic skills and information retention, especially in post secondary education where increasingly complex subjects are explored. Active recall-based strategies have been identified as particularly effective for long-term learning. This systematic review investigates the effectiveness of various active recall-based learning strategies for improving academic performance and self-efficacy in higher education students. METHODS: A systematic review of peer-reviewed articles was conducted with a priori criteria by searching PubMed, ScienceDirect, JSTOR, PsycInfo, and Web of Science databases. Search results were screened/extracted and reconciled by two independent authors with the use of a piloted screening tool. Included studies were assessed for quality and risk of bias using the GRADE Quality Assessment Tool for Quantitative Studies. Three overarching study strategies were extracted for further investigation including flashcards, practice testing or retrieval practice, and concept mapping. Within each category, three additional unique search strings were searched, screened, and extracted. A qualitative analysis of the studies was provided. RESULTS: Among the appraised articles, flashcards were found to be popular and correlated with higher GPA and test scores. Self-testing, retrieval practice, and concept mapping were also effective but under-utilized. Concept mapping was found to boost student confidence. CONCLUSION: Active recall strategies exhibit promise for effective learning and additional research in these developing field can support academic pursuits.

RESUMEN

Objective: Situated in Children's National Hospital (CNH)'s Neuropsychology Division, the Gender and Autism Program (GAP) is the first clinical service dedicated to the needs of autistic gender-diverse/transgender youth. This study describes GAP clinical assessment profiles and presents a multi-perspective programmatic review of GAP evaluation services. Method: Seventy-five consecutive gender- and neuropsychologically-informed GAP evaluations were analyzed, including demographics, gender and autism characterization, and primary domains evaluated. Three program-based Delphi studies were conducted and identify: clinician priorities and challenges in providing care, program administrator lessons learned and ongoing barriers, and considerations adapting this model for a rural academic medical center. Results: Nearly two-thirds of referrals were transfeminine. Most youth had existing autism diagnoses; of those undiagnosed, three-quarters were found to be autistic. Five goals of evaluations were identified: Mental health was always assessed, and most evaluations also assessed gender-related needs in the context of autism neurodiversity. Neuropsychological characterization of strengths and challenges informed personalized accommodations to support youth gender-related self-advocacy. Clinicians emphasized frequent youth safety concerns. Administrators emphasized the need for specialized training for working with families. Components for adaptation of the GAP in a rural academic medical center were identified. Conclusions: Since its founding, the GAP has proven a sustainable neuropsychology-based service with consistent referral flow and insurance authorizations. Capturing staff perspectives through rigorous Delphi methods, and addressing the GAP's feasibility and replicability, this study provides a road map for replicating this service. We also highlight GAP training of specialist clinicians, fundamental to addressing the desperate shortage of providers in this field.

RESUMEN

OBJECTIVES: To describe the characteristics of individuals undergoing toxicology testing at delivery for a sole indication of cannabis use and to evaluate the rate of unexpected positive toxicology testing results among this cohort. METHODS: This retrospective cohort study included dyads with a maternal history of cannabis use who underwent peripartum toxicology testing between 2016 and 2020 at 5 birthing hospitals in Massachusetts. We collected information on maternal demographic characteristics and toxicology test results and reviewed records of dyads with unexpected positive results to identify additional social risk factors and clinical outcomes. RESULTS: Of 60 608 live births reviewed, 1924 dyads underwent toxicology testing, including 614 (31.9%) for a sole indication of cannabis use. Significantly greater percentages of patients in the cannabis cohort were <25 years old (32.4% vs 6.1% of the birthing population, P <.001), non-Hispanic Black (32.4% vs 8.1%, P < .001), Hispanic or Latino (30.5% vs 15.5%), American Indian/Alaskan (0.7% vs 0.1%), and publicly insured (39.9% vs 15.6%, P <.001). Eight of the 614 dyads (1.3%) had an unexpected positive toxicology test result, including 2 (0.3%) unexpectedly positive for opioids. Seven dyads (1.1%) had false positive test results for unexpected substances. Only 1 test result changed clinical management; a urine test positive for opioids prompted monitoring (but not medication) for neonatal opioid withdrawal syndrome. CONCLUSIONS: Toxicology testing of patients for a sole indication of cannabis use, without other risk factors, may be of limited utility in elucidating other substance use and may exacerbate existing disparities in perinatal outcomes.

RESUMEN

BACKGROUND AND OBJECTIVES: Clinicians often communicate complex, uncertain, and distressing information about neurologic prognosis to parents of critically ill infants. Although communication tools have been developed in other disciplines and settings, none address the unique needs of the neonatal and pediatric neurology context. We aimed to develop a parent-informed framework to guide clinicians in communicating information about neurologic prognosis. METHODS: Parents of infants with neurologic conditions in the intensive care unit were enrolled in a longitudinal study of shared decision-making from 2018 to 2020. Parents completed semistructured interviews following recorded family meetings with the health care team, at hospital discharge, and 6 months after discharge. All interviews targeted information about parent preferences for prognostic disclosure. We analyzed the data using a conventional content analysis approach. Two study team members independently coded all interview transcripts, and discrepancies were resolved in consensus. We used NVIVO 12 qualitative software to index and organize codes. RESULTS: Fifty-two parents of 37 infants completed 123 interviews. Parents were predominantly mothers (n = 37/52, 71%) with a median age of 31 (range 19-46) years. Half were Black (n = 26/52, 50%), and a minority reported Hispanic ethnicity (n = 2/52, 4%). Inductive analysis resulted in the emergence of 5 phases of prognostic communication (Approach, Learn, Inform, Give support, and Next steps: ALIGN): (1) Approach: parents appreciated receiving consistent information about their child's neurologic outcome from clinicians who knew their child well. (2) Learn: parents valued when clinicians asked them how they preferred receiving information and what they already knew about their child's outcome prior to information delivery. (3) Inform: parents valued honest, thorough, and balanced information that disclosed prognostic uncertainty and acknowledged room for hope. (4) Give support: parents valued empathic communication and appreciated clinicians who offered real-time emotional support. (5) Next steps: parents appreciated clinicians who connected them to resources, including peer support. DISCUSSION: The ALIGN framework offers a novel, parent-informed strategy to effectively communicate neurologic prognosis. Although ALIGN represents key elements of a conversation about prognosis, each clinician can adapt this framework to their own approach. Future work will assess the effectiveness of this framework on communication quality and prognostic understanding.
