Specific Birth Defects Following Antiseizure Medications Used By Pregnant Women With Epilepsy.

Background and Objectives: Previous research has been limited in the comprehensive study of associations between the use of individual antiseizure medications (ASMs) in pregnancy and specific groups of birth defects, and systematic reviews and meta-analyses on the topic are limited by pooled samples and study designs. This study investigated birth defects related to ASM use in pregnancy in children born to women with epilepsy in Sweden over 20 years. Methods: We used data from Swedish national registers to follow a cohort of 17,996 children born to women diagnosed with epilepsy any time before conception in Sweden from 1996 to 2016, following them through 2017. We examined maternal-reported use of the 4 most commonly reported ASMs: lamotrigine (n = 2,148, 11.9%), carbamazepine (n = 1,940, 10.8%), valproic acid (n = 1,043, 5.80%), and levetiracetam (n = 587, 3.26%). We identified birth defects using diagnoses recorded at the time of discharge from the hospital and inpatient and outpatient diagnoses recorded in the first year of life. Models were estimated in a stepped fashion: unadjusted, adjusted for covariates, among a subcohort born to women diagnosed 10 years before conception (n = 14,586), and restricted to monotherapy. Results: Valproic acid use in pregnancy had the strongest and most widespread associations with birth defects in children, with carbamazepine also having links to several birth defects, including respiratory system and genital organ defects. Lamotrigine use in pregnancy was associated with cleft lip/palate and chromosomal abnormalities. Levetiracetam was most often used with other ASMs and preliminarily associated with many birth defects. Discussion: Our findings support avoidance of valproic acid use in pregnancy whenever possible. Lamotrigine and carbamazepine may be safer alternatives. However, these medications were also associated with certain birth defects, including some not reported previously. We are among the first to examine the possible effects of levetiracetam use in pregnancy, though more research is needed to investigate this further.

Genetic Deletion of ß-Arrestin 2 From the Subfornical Organ and Other Periventricular Nuclei in the Brain Alters Fluid Homeostasis and Blood Pressure.

BACKGROUND: ANG (angiotensin II) elicits dipsogenic and pressor responses via activation of the canonical Gαq (G-protein component of the AT1R [angiotensin type 1 receptor])-mediated AT1R in the subfornical organ. Recently, we demonstrated that ARRB2 (ß-arrestin 2) global knockout mice exhibit a higher preference for salt and exacerbated pressor response to deoxycorticosterone acetate salt. However, whether ARRB2 within selective neuroanatomical nuclei alters physiological responses to ANG is unknown. Therefore, we hypothesized that ARRB2, specifically in the subfornical organ, counterbalances maladaptive dipsogenic and pressor responses to the canonical AT1R signaling. METHODS: Male and female Arrb2FLOX mice received intracerebroventricular injection of either adeno-associated virus (AAV)-Cre-GFP (green fluorescent protein) to induce brain-specific deletion of ARRB2 (Arrb2ICV-Cre). Arrb2FLOX mice receiving ICV-AAV-GFP were used as control (Arrb2ICV-Control). Infection with ICV-AAV-Cre primarily targeted the subfornical organ with few off targets. Fluid intake was evaluated using the 2-bottle choice paradigm with 1 bottle containing water and 1 containing 0.15 mol/L NaCl. RESULTS: Arrb2ICV-Cre mice exhibited a greater pressor response to acute ICV-ANG infusion. At baseline conditions, Arrb2ICV-Cre mice exhibited a significant increase in saline intake compared with controls, resulting in a saline preference. Furthermore, when mice were subjected to water-deprived or sodium-depleted conditions, which would naturally increase endogenous ANG levels, Arrb2ICV-Cre mice exhibited elevated saline intake. CONCLUSIONS: Overall, these data indicate that ARRB2 in selective cardiovascular nuclei in the brain, including the subfornical organ, counterbalances canonical AT1R responses to both exogenous and endogenous ANG. Stimulation of the AT1R/ARRB axis in the brain may represent a novel strategy to treat hypertension.

Early Remission of Opioid Use Disorder in an Adolescent Using Buprenorphine Extended - Release Subcutaneous Injection: A Case Report.

Opioid use disorder (OUD) continues to be a major public health crisis, with the current epidemic being driven by synthetic opioids such as illicitly manufactured fentanyl. While medications exist to treat OUD, only sublingual and subdermal buprenorphine formulations are approved for patients aged 16-17 years. Furthermore, almost all pediatric patients who are diagnosed with OUD do not receive medication as treatment. This case describes the innovative use of buprenorphine extended-release subcutaneous injection in a 17-year-old with OUD who has achieved early remission after four months of treatment. This case supports the use of buprenorphine extended-release in pediatric patients who are at high risk. While buprenorphine extended-release injections are not Food and Drug Administration-approved for pediatric patients, the increase in adolescent overdose deaths and lack of access to treatment in this age group support the need for increased research and treatment options for youth with OUD.

High pesticide exposure and risk to bees in pollinator plantings adjacent to conventionally managed blueberry fields.

Wildflower plantings adjacent to agricultural fields provide diverse floral resources and nesting sites for wild bees. However, their proximity to pest control activities in the crop may result in pesticide exposure if pesticides drift into pollinator plantings. To quantify pesticide residues in pollinator plantings, we sampled flowers and soil from pollinator plantings and compared them to samples from unenhanced field margins and crop row middles. At conventionally managed farms, flowers from pollinator plantings had similar exposure profiles to those from unenhanced field margins or crop row middles, with multiple pesticides and high and similar risk quotient (RQ) values (with pollinator planting RQ: 3.9; without pollinator planting RQ: 4.0). Whereas samples from unsprayed sites had significantly lower risk (RQ: 0.005). Soil samples had overall low risk to bees. Additionally, we placed bumble bee colonies (Bombus impatiens) in field margins of crop fields with and without pollinator plantings and measured residues in bee-collected pollen. Pesticide exposure was similar in pollen from sites with or without pollinator plantings, and risk was generally high (with pollinator planting RQ: 0.5; without pollinator planting RQ: 1.1) and not significant between the two field types. Risk was lower at sites where there was no pesticide activity (RQ: 0.3), but again there was no significant difference between management types. The insecticide phosmet, which is used on blueberry farms for control of Drosophila suzukii, accounted for the majority of elevated risk. Additionally, analysis of pollen collected by bumble bees found no significant difference in floral species richness between sites with or without pollinator plantings. Our results suggest that pollinator plantings do not reduce pesticide risk and do not increase pollen diversity collected by B. impatiens, further highlighting the need to reduce exposure through enhanced IPM adoption, drift mitigation, and removal of attractive flowering weeds prior to insecticide applications.

Preliminary examination of ADHD inattentive and cognitive disengagement syndrome symptoms in relation to probe-caught mind-wandering during a sustained attention to response task.

OBJECTIVE: The role of mind-wandering- periods of internally-directed distractibility - among patients with attention-deficit/hyperactivity disorder (ADHD) has recently garnered attention, though few studies have assessed mind-wandering using thought probes during a sustained attention to response task (SART) or examined the possible role of cognitive disengagement syndrome (CDS) symptoms. We examined whether parent- and/or teacher-reported ADHD-inattentive (ADHD-IN) or CDS symptoms were independently associated with probe-caught mind-wandering. METHODS: Fifty-four children (ages 9-12; 35.2% female) completed a SART with thought probes inquiring about various on- and off-task thoughts, including mind-wandering and distraction. Questionnaires provided information on demographics, medication treatment, and parent- and teacher-reported ADHD-IN and CDS symptoms. Regression models were estimated separately by informant to examine whether ADHD-IN or CDS symptoms were uniquely associated with mind-wandering or distraction frequency during the SART. RESULTS: Higher teacher-reported CDS ratings, but not ADHD-IN ratings, were uniquely associated with more probe-caught mind-wandering. No significant findings related to parent-reported symptoms or probe-caught distraction were observed. CONCLUSIONS: These preliminary findings add to an emerging body of work pointing to CDS as more consistently or strongly associated than ADHD-IN with mind-wandering. Theoretical and clinical implications are discussed.

Examining daily stimulant medication use and sleep in adolescents with ADHD.

Research has been inconclusive as to whether stimulant treatment causes or exacerbates sleep problems in adolescents with ADHD. This study examined sleep differences in adolescents with ADHD as a function of stimulant use. Participants were adolescents with ADHD (N = 159, ages 12-14). Parents reported on receipt of stimulant treatment (n = 92, 57.86%; n = 47 amphetamines, n = 45 methylphenidate). Adolescents wore actigraphs and completed daily diaries assessing sleep and daily use of stimulants for 2 weeks. Sleep parameters included daily-reported bedtime, sleep onset latency (SOL), sleep duration, daytime sleepiness, and difficulty waking the following morning; and actigraphy-measured sleep onset time, total time in bed, and sleep efficiency. We estimated between- and within-individual associations between stimulant medication use and sleep indices with all stimulants, after removing adolescents using sleep aids and weekend days, and as a function of stimulant type. Adolescent sleep did not differ between those receiving and not receiving stimulant treatment. Within individuals using stimulants, we largely observed no significant differences between medicated and unmedicated days, though findings were most often significant for school days only. Small effects were found indicating longer SOL, later sleep onset time, and more daytime sleepiness related to medication use. In contrast, there were slight improvements to sleep duration and sleep efficiency related to methylphenidate use, though methylphenidate was also associated with later sleep onset time and more daytime sleepiness. Given the inconsistent and small effects, findings suggest that stimulant medication may impact sleep, but does not appear to be a primary contributor to sleep problems in adolescents with ADHD.

Adverse birth outcomes related to concentrations of per- and polyfluoroalkyl substances (PFAS) in maternal blood collected from pregnant women in 1960-1966.

BACKGROUND: Prior animal and epidemiological studies suggest that per- and polyfluoroalkyl substances (PFAS) exposure may be associated with reduced birth weight. However, results from prior studies evaluated a relatively small set of PFAS. OBJECTIVES: Determine associations of gestational PFAS concentrations in maternal serum samples banked for 60 years with birth outcomes. METHODS: We used data from 97 pregnant women from Boston and Providence that enrolled in the Collaborative Perinatal Project (CPP) study (1960-1966). We quantified concentrations of 27 PFAS in maternal serum in pregnancy and measured infant weight, height and ponderal index at birth. Covariate-adjusted associations between 11 PFAS concentrations (>75% detection limits) and birth outcomes were estimated using linear regression methods. RESULTS: Median concentrations of PFOA, PFNA, PFHxS, and PFOS were 6.189, 0.330, 14.432, and 38.170 ng/mL, respectively. We found that elevated PFAS concentrations during pregnancy were significantly associated with lower birth weight and ponderal index at birth, but no significant associations were found with birth length. Specifically, infants born to women with PFAS concentrations ≥ median levels had significantly lower birth weight (PFOS: ß = -0.323, P = 0.006; PFHxS: ß = -0.292, P = 0.015; PFOA: ß = -0.233, P = 0.03; PFHpS: ß = -0.239, P = 0.023; PFNA: ß = -0.239, P = 0.017). Similarly, women with PFAS concentrations ≥ median levels had significantly lower ponderal index (PFHxS: ß = -0.168, P = 0.020; PFHxA: ß = -0.148, P = 0.018). CONCLUSIONS: Using data from this US-based cohort study, we found that 1) maternal PFAS levels from the 1960s exceeded values in contemporaneous populations and 2) that gestational concentrations of certain PFAS were associated with lower birth weight and infant ponderal index. Additional studies with larger sample size are needed to further examine the associations of gestational exposure to individual PFAS and their mixtures with adverse birth outcomes.

Krüppel-like factor 4 in transcriptional control of the three unique isoforms of Agouti-related peptide in mice.

Agouti-related peptide (AgRP/Agrp) within the hypothalamic arcuate nucleus (ARC) contributes to the control of energy balance, and dysregulated Agrp may contribute to metabolic adaptation during prolonged obesity. In mice, three isoforms of Agrp are encoded via distinct first exons. Agrp-A (ENSMUST00000005849.11) contributed 95% of total Agrp in mouse ARC, whereas Agrp-B (ENSMUST00000194654.2) dominated in placenta (73%). Conditional deletion of Klf4 from Agrp-expressing cells (Klf4Agrp-KO mice) reduced Agrp mRNA and increased energy expenditure but had no effects on food intake or the relative abundance of Agrp isoforms in the ARC. Chronic high-fat diet feeding masked these effects of Klf4 deletion, highlighting the context-dependent contribution of KLF4 to Agrp control. In the GT1-7 mouse hypothalamic cell culture model, which expresses all three isoforms of Agrp (including Agrp-C, ENSMUST00000194091.6), inhibition of extracellular signal-regulated kinase (ERK) simultaneously increased KLF4 binding to the Agrp promoter and stimulated Agrp expression. In addition, siRNA-mediated knockdown of Klf4 reduced expression of Agrp. We conclude that the expression of individual isoforms of Agrp in the mouse is dependent upon cell type and that KLF4 directly promotes the transcription of Agrp via a mechanism that is superseded during obesity.NEW & NOTEWORTHY In mice, three distinct isoforms of Agouti-related peptide are encoded via distinct first exons. In the arcuate nucleus of the hypothalamus, Krüppel-like factor 4 stimulates transcription of the dominant isoform in lean mice, but this mechanism is altered during diet-induced obesity.

Better together: utilizing an interprofessional course and escape room to educate healthcare students about opioid use disorder.

BACKGROUND: The aim of the present study was to determine the impact of an innovative interprofessional educational activity on healthcare professional students' learning. The educational activity targeted student knowledge of opioid use disorder (OUD) and perceptions of working with an interprofessional team while caring for patients with OUD. METHODS: Students from nursing, pharmacy, physician assistant, dentistry, social work, and medicine programs were recruited to participate in the interprofessional educational activity. The educational experience included seven asynchronous modules and a virtual synchronous escape room. Prior to the educational programming, participants completed a pre-survey that assessed their knowledge and attitudes towards working on an interprofessional team and perceptions of patients with OUD. The asynchronous modules were required in order to participate in the escape room and each module contained its own pre/post quiz to assess student knowledge. RESULTS: A total of 402 students participated in the course. Prior to participating in the course, students disagreed that they had extensive educational experience with SUD (2.45 ± 0.79). The students displayed significant improvement in the knowledge based areas after completing the seven asynchronous modules. The largest significant area of knowledge-based improvement was seen in treatment of OUD where on the pre-quiz 65.54 ± 20.21% were answered correctly compared to 95.97 ± 9.61% on the post-quiz. Participation in the escape room significantly changed the students' perceptions of working in interprofessional teams while managing patients with OUD. Of the eleven perception variables assessed, seven showed a significant increase in the post-survey. Following the escape room, participants also strongly agreed that they now would refer patients to colleagues in other disciplines. CONCLUSIONS: An interprofessional educational experience including both an asynchronous course and virtual synchronous escape room can increase participant knowledge around OUD and may improve student perceptions of working with an interprofessional team and caring for patients with OUD.

Mitochondrial-targeted antioxidant attenuates preeclampsia-like phenotypes induced by syncytiotrophoblast-specific Gαq signaling.

Syncytiotrophoblast stress is theorized to drive development of preeclampsia, but its molecular causes and consequences remain largely undefined. Multiple hormones implicated in preeclampsia signal via the Gαq cascade, leading to the hypothesis that excess Gαq signaling within the syncytiotrophoblast may contribute. First, we present data supporting increased Gαq signaling and antioxidant responses within villous and syncytiotrophoblast samples of human preeclamptic placenta. Second, Gαq was activated in mouse placenta using Cre-lox and DREADD methodologies. Syncytiotrophoblast-restricted Gαq activation caused hypertension, kidney damage, proteinuria, elevated circulating proinflammatory factors, decreased placental vascularization, diminished spiral artery diameter, and augmented responses to mitochondrial-derived superoxide. Administration of the mitochondrial-targeted antioxidant Mitoquinone attenuated maternal proteinuria, lowered circulating inflammatory and anti-angiogenic mediators, and maintained placental vascularization. These data demonstrate a causal relationship between syncytiotrophoblast stress and the development of preeclampsia and identify elevated Gαq signaling and mitochondrial reactive oxygen species as a cause of this stress.

Multi-method examination of cognitive disengagement syndrome and ADHD inattentive symptoms in relation to early adolescents' academic functioning.

Cognitive disengagement syndrome (CDS), previously referred to as sluggish cognitive tempo, is a set of symptoms characterized by excessive daydreaming, mental fogginess, and slowed behavior/thinking. Studies examining the association between CDS and academic functioning have reported mixed findings and have relied upon limited measures of CDS, broad ratings of academic impairment, and/or focused only on elementary-aged children. The current study examined the relationship between CDS and academic functioning in adolescents using a comprehensive, multi-informant, multi-method design. Participants were 302 adolescents (Mage = 13.17 years; 44.7% female; 81.8% White; 52% with ADHD) recruited in the fall of their 8th grade. Above and beyond ADHD inattentive symptoms, CDS symptoms were related to poorer homework performance, lower math fluency, and lower daily academic motivation across multiple informants, and teacher-reported CDS symptoms were related to lower grades. Findings were not moderated by ADHD diagnosis, suggesting that associations between CDS and academic outcomes do not differ for adolescents with and without ADHD. Findings demonstrate that CDS symptoms are uniquely associated with daily academic difficulties as well as global indices of academic performance. These findings have implications for assessing and monitoring CDS symptoms in interventions aiming to improve the academic functioning in adolescents with and without ADHD.

Perioperative Chemotherapy and Chemoradiotherapy for Patients With Resectable and Borderline Resectable Pancreatic Adenocarcinoma.

OBJECTIVES: Pancreatic ductal adenocarcinoma (PDA) is the third most common cause of cancer death in the United States. Most patients who undergo resection develop recurrence. Standard treatment confers a median overall survival (OS) of 24 months. Exposure to alternate regimens may prevent chemoresistance. This study evaluated multiagent perioperative therapy for potentially resectable PDA patients to improve OS. METHODS: A single center, phase 2, trial of patients with resectable or borderline resectable PDA. Patients received neoadjuvant therapy with induction chemotherapy (gemcitabine, docetaxel, capecitabine) for 3 cycles, chemoradiation (intensity-modulated radiation therapy with capecitabine and oxaliplatin) followed by surgery, and 2 months of adjuvant gemcitabine and oxaliplatin and 2 months of gemcitabine. The primary endpoint was OS. The secondary endpoint was recurrence-free survival (RFS). RESULTS: Thirty-two eligible patients were enrolled. Twenty-two patients underwent surgical resection. After a median follow-up of 56.8 months, mOS was 31.6 months (95% confidence interval [CI], 14.2-58.1) for all patients, 58.1 months (95% CI, 31.6 to NR) for those who completed surgery. The mRFS was 31.3 months (95% CI, 12.5 to NR). CONCLUSIONS: Perioperative therapy with GTX, chemoradiotherapy, and adjuvant GemOx/Gem resulted in promising survival of 58 months for patients who underwent resection and may represent another treatment option for PDA.

Racial disparities in the screening mammography continuum within a heterogeneous health care system.

BACKGROUND: Decreased mammography drives breast cancer disparities. Black women have lower rates of mammography completion than White women, and this contributes to disparities in outcomes. Points of disparity along the continuum for screening mammography remain underresearched. METHODS: The authors compared mammography referrals for Black and White women aged 40-74 years at a heterogeneous academic medical center. Completion of steps of the screening mammography continuum was compared between Black and White women within two age cohorts: 40-49 and 50-74 years. Multivariable logistic regression was used to evaluate the association between race and mammogram completion. RESULTS: Among 26,476 women, 3090 (12%) were Black, and 23,386 (88%) were White. Among Black women aged 50-74 years who were due for mammography, 40% had referrals, 39% were scheduled, and 21% completed mammography; the corresponding values for White women were 42%, 41%, and 27%, respectively. Similar differences in referral outcomes were noted for women aged 40-49 years, although Black women had lower rates of provider-initiated referrals (9% vs. 13%). Adjusted analyses for those aged 40-49 and 50-74 years demonstrated an association between Black race and lower rates of mammography completion (odds ratio [OR] for 40-49 years, 0.74; 95% CI, 0.57-0.95; p = .02; OR for 50-74 years, 0.85; 95% CI, 0.74-0.98; p = .02). In multivariable analyses, noncommercial insurance and higher comorbidity were associated with lower rates of mammography. Provider-initiated referral was positively correlated to mammogram completion. CONCLUSIONS: Black race was associated with 15%-26% lower mammography completion (adjusted). Both groups experienced the highest attrition after scheduling mammograms, although attrition was more precipitous for Black women. These findings have implications for future interventions, including increasing provider-initiated referrals and decreasing barriers to attending scheduled mammograms.

Genetic Ablation of Prorenin Receptor in the Rostral Ventrolateral Medulla Influences Blood Pressure and Hydromineral Balance in Deoxycorticosterone-Salt Hypertension.

Non-enzymatic activation of renin via its interaction with prorenin receptor (PRR) has been proposed as a key mechanism of local renin-angiotensin system (RAS) activation. The presence of renin and angiotensinogen has been reported in the rostral ventrolateral medulla (RVLM). Overactivation of bulbospinal neurons in the RVLM is linked to hypertension (HTN). Previous studies have shown that the brain RAS plays a role in the pathogenesis of the deoxycorticosterone (DOCA)-salt HTN model. Thus, we hypothesized that PRR in the RVLM is involved in the local activation of the RAS, facilitating the development of DOCA-salt HTN. Selective PRR ablation targeting the RVLM (PRRRVLM-Null mice) resulted in an unexpected sex-dependent and biphasic phenotype in DOCA-salt HTN. That is, PRRRVLM-Null females (but not males) exhibited a significant delay in achieving maximal pressor responses during the initial stage of DOCA-salt HTN. Female PRRRVLM-Null subsequently showed exacerbated DOCA-salt-induced pressor responses during the "maintenance" phase with a maximal peak at 13 d on DOCA-salt. This exacerbated response was associated with an increased sympathetic drive to the resistance arterioles and the kidney, exacerbated fluid and sodium intake and output in response to DOCA-salt, and induced mobilization of fluids from the intracellular to extracellular space concomitant with elevated vasopressin. Ablation of PRR suppressed genes involved in RAS activation and catecholamine synthesis in the RVLM but also induced expression of genes involved in inflammatory responses. This study illustrates complex and sex-dependent roles of PRR in the neural control of BP and hydromineral balance through autonomic and neuroendocrine systems. Graphical abstract.

Cardiometabolic Effects of DOCA-Salt in Mice Depend on Ambient Temperature.

BACKGROUND: Mice prefer warmer environments than humans. For this reason, behavioral and physiological thermoregulatory responses are engaged by mice in response to a standard room temperature of 22 to 24 °C. Autonomic mechanisms mediating thermoregulatory responses overlap with mechanisms activated in hypertension, and, therefore, we hypothesized that housing at thermoneutral temperatures (TNs; 30 °C) would modify the cardiometabolic effects of deoxycorticosterone acetate (DOCA)-salt in mice. METHODS: The effects of DOCA-salt treatment upon ingestive behaviors, energy expenditure, blood pressure, heart rate (HR), and core temperature were assessed in C57BL/6J mice housed at room temperature or TN. RESULTS: Housing at TN reduced food intake, energy expenditure, blood pressure, and HR and attenuated HR responses to acute autonomic blockade by chlorisondamine. At room temperature, DOCA-salt caused expected increases in fluid intake, sodium retention in osmotically inactive pools, blood pressure, core temperature, and also caused expected decreases in fat-free mass, total body water, and HR. At TN, the effects of DOCA-salt upon fluid intake, fat gains, hydration, and core temperature were exaggerated, but effects on energy expenditure and HR were blunted. Effects of DOCA-salt upon blood pressure were similar for 3 weeks and exaggerated by TN housing in the fourth week. CONCLUSIONS: Ambient temperature robustly influences behavioral and physiological functions in mice, including metabolic and cardiovascular phenotype development in response to DOCA-salt treatment. Studying cardiometabolic responses of mice at optimal ambient temperatures promises to improve the translational relevance of rodent models.

Racial and sex differences in tumor genomics in urothelial carcinoma.

PURPOSE: Differences in bladder cancer outcomes have been demonstrated by sex and race/ethnicity, with studies showing a higher burden of adverse outcomes among women and racially minoritized populations. Despite these epidemiologic differences, populations with disproportionally adverse outcomes are often underrepresented in genomic cohorts. This exclusion impacts the accuracy and generalizability of genomic studies in bladder cancer and has the potential to widen disparities by sex and/or race/ethnicity. BASIC PROCEDURES: We analyzed pooled somatic mutational data from publicly available cohorts in the cBioPortal open access platform. FINDINGS: A total of 796 unique patients were identified. Average age for the cohort was 67 years (range: 25-98 years), 188 (24%) were female, and the majority were White (n = 423, 85% among those who report race). Median total mutation count was 91 (IQR: 20, 202) per patient. We used multivariable logistic regression to independently evaluate the association between race/sex and mutation status in each of 122 genes of interest, identified from TCGA, adjusting for age and bladder cancer invasive status. In adjusted analyses, male sex was associated with increased risk of mutation in ARID1A, CHD6, and NCOR1 compared with female sex. White race was associated with increased risk of mutation in ARID1A, EP300, PIK3CA, and TP53 and decreased risk of mutation in HRAS compared with non-White race. CONCLUSIONS: These differences highlight the importance of enriching cohorts for female and non-White patients in genomic studies and clinical trials, especially as we test the use of molecular biomarkers to personalize care for patients with bladder cancer.

Identity and diversity of pollens collected by two managed bee species while in blueberry fields for pollination.

The nutritional needs and foraging behavior of managed bees often lead to pollen collection from flowers other than the focal crop during crop pollination. To understand the pollen needs and preferences of managed bees during blueberry pollination, we identified pollen collected by Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae) and Bombus impatiens Cresson, 1863 (Hymenoptera: Apidae) colonies across two years. Bumble bees collected a wider diversity of pollens compared to honey bees, whereas honey bees were more focused on abundant resources. Despite blueberries being the most abundant resource in the landscape, it was not the most collected pollen by either bee species in 2018. However, it was the most collected pollen by bumble bees in 2019 and they collected substantially more blueberry pollen than honey bees in both years. In 2018, buckthorn, Rhamnus L. (Rosales: Rhamnaceae) or Frangula Mill. (Rosales: Rhamnaceae), and willow, Salix L. (Malpighiales: Salicaceae), pollens were abundantly collected by both bee species. In 2019, cherry, Prunus L. (Rosales: Rosaceae), and willow (Salix) pollens were collected at high proportions by both species. Brambles, Rubus L. (Rosales: Rosaceae), and white clover, Trifolium repens L. (Fabales: Fabaceae), were also common pollen sources for honey bees, whereas oak, Quercus L. (Fagales: Fagaceae), was collected by bumble bees. Landscape analyses also revealed that certain land cover types were positively correlated with the collection of preferred pollen types. Herbaceous wetlands were associated with collection of buckthorn (Rhamnus/Frangula), willow (Salix), and cherry (Prunus) pollen, which were primary pollen resources for both bee species. There was no correlation between landscape diversity and pollen diversity, suggesting that colonies forage based on nutritional requirements rather than resource availability.

Improving Communication in the Medical Intensive Care Unit Through Standardization of Handoff Format: A Quality Improvement Project.

Objective: To decrease interruptions in handoff, increase compliance with a structured verbal handoff format, and increase compliance with handoff template completion in electronic medical records without increasing the length of handoff time. Patients and Methods: The project timeline was from April 1, 2019, to February 1, 2020. Define phase data were obtained through a survey of stakeholders to identify the gap in needs. The baseline data included components from the illness severity, patient summary, action list, situational awareness and contingency plans, and synthesis by receiver (IPASS) handoff tool because this tool best aligned with information identified in the define phase. Observational data were collected in person and reviewed via audio recording for accuracy. Results were analyzed to determine adherence to the chosen intervention, the IPASS handoff tool, on which the stakeholders were educated and assessed prior to implementation. Five plan-do-study-act cycles were completed over 3 months to optimize the intervention. Final data were collected and analyzed using the same method as baseline data. Results: After implementation of the IPASS handoff tool, there were more care plan components mentioned in the provider handoffs across all unique IPASS components, there were fewer observed distracting events, and there was increased compliance with electronic medical record handoff completion. The time of handover increased by 3 minutes. Conclusion: A standardized handoff tool improved communication during provider handoffs by increasing the mention of pertinent details and reducing distracting events during handoff.

Elevated EVL Methylation Level in the Normal Colon Mucosa Is a Potential Risk Biomarker for Developing Recurrent Adenomas.

BACKGROUND: Individuals with adenomatous colorectal polyps undergo repeated colonoscopy surveillance to identify and remove metachronous adenomas. However, many patients with adenomas do not develop recurrent adenomas. Better methods to evaluate who benefits from increased surveillance are needed. We evaluated the use of altered EVL methylation as a potential biomarker for risk of recurrent adenomas. METHODS: Patients with ≥1 colonoscopy had EVL methylation (mEVL) measured with an ultra-accurate methylation-specific droplet digital PCR assay on normal colon mucosa. The association between EVL methylation levels and adenoma or colorectal cancer was evaluated using three case/control definitions in three models: unadjusted (model 1), adjusting for baseline characteristics (model 2), and an adjusted model excluding patients with colorectal cancer at baseline (model 3). RESULTS: Between 2001 and 2020, 136 patients were included; 74 healthy patients and 62 patients with a history of colorectal cancer. Older age, never smoking, and baseline colorectal cancer were associated with higher levels of mEVL (P ≤ 0.05). Each log base 10 difference in mEVL was associated with an increased risk of adenoma(s) or cancer at/after baseline for model 1 [OR, 2.64; 95% confidence interval (CI), 1.09-6.36], and adenoma(s) or cancer after baseline for models 1 (OR, 2.01; 95% CI, 1.04-3.90) and model 2 (OR, 3.17; 95% CI, 1.30-7.72). CONCLUSIONS: Our results suggest that EVL methylation level detected in the normal colon mucosa has the potential to be a biomarker for monitoring the risk for recurrent adenomas. IMPACT: These findings support the potential utility of EVL methylation for improving the accuracy for assigning risk for recurrent colorectal adenomas and cancer.

Pharmacologic Management of Cognitive Disengagement Syndrome (CDS) and Implications for Attention-Deficit/Hyperactivity Disorder (ADHD) Treatment: Emerging Treatments and Recommendations for Future Research.

Although the study of cognitive disengagement syndrome (CDS; previously called sluggish cognitive tempo) first emerged in the 1980s, very little is known about treating CDS or its impact on evidence-based interventions for attention-deficit/hyperactivity disorder (ADHD) with which it frequently co-occurs. The objective of this leading article was to investigate the existing evidence on medication treatment and CDS, including studies that have examined CDS response to medication and CDS as a moderator of ADHD treatment response. A total of seven studies were identified. At present, the limited existing literature suggests that psychostimulants such as methylphenidate and lisdexamfetamine, as well as atomoxetine, may improve CDS symptoms, although replication and research on related medications is needed. However, there are indications that CDS symptoms may predict a reduced response to methylphenidate in children with ADHD. Although untested, research on the neurobiological, neuropsychological, and behavioral correlates of CDS point to a possible benefit of other ADHD medications (e.g., guanfacine), medications that treat narcolepsy (e.g., modafinil), and medications traditionally used to treat depression and anxiety (e.g., viloxazine, bupropion, fluvoxamine), some of which have also recently been used in ADHD management. The article concludes with recommendations for future research on pharmacologic treatment and CDS.
