Prenatal Cannabis Use and Maternal Pregnancy Outcomes.

Importance: Many studies have evaluated whether in utero cannabis exposure is associated with fetal and neonatal outcomes, yet little is known about whether prenatal cannabis use is associated with maternal health outcomes during pregnancy. Objective: To evaluate whether prenatal cannabis use is associated with maternal health outcomes during pregnancy. Design, Setting, and Participants: This population-based retrospective cohort study included pregnancies in Northern California from January 2011 to December 2019 that lasted 20 weeks or longer and were screened for prenatal cannabis use. Exposures: Prenatal cannabis use was defined as any self-reported use during early pregnancy or a positive toxicology test result based on universal screening at entrance to prenatal care (approximately 8-10 weeks' gestation). Self-reported frequency of use (daily, weekly, monthly or less, never, unknown), use defined only by self-report, and use defined only by toxicology test results were examined. Main Outcomes and Measures: Electronic health record data were used to define the following outcomes: gestational hypertension, preeclampsia, eclampsia, gestational diabetes, gestational weight gain greater and less than guidelines, placenta previa, placental abruption, placenta accreta, and severe maternal morbidity. Adjusted risk ratios (aRRs) were calculated using a modified Poisson regression. Results: The sample (n = 316 722 pregnancies; 250 221 unique individuals) included 84 039 (26.5%) Asian/Pacific Islander, 20 053 (6.3%) Black, 83 145 (26.3%) Hispanic, and 118 333 (37.4%) White individuals; the mean (SD) age was 30.6 (5.4) years. Overall, 20 053 (6.3%) screened positive for prenatal cannabis use; 2.9% were positive by self-report, 5.3% by toxicology testing, and 1.8% by both. The frequency of cannabis use was 1930 (0.6%) daily, 2345 (0.7%) weekly, 4892 (1.5%) monthly or less, and 10 886 (3.4%) unknown. Prenatal cannabis use was associated with greater risk of gestational hypertension (aRR, 1.17; 95% CI, 1.13-1.21), preeclampsia (aRR, 1.08; 95% CI, 1.01-1.15), weight gain less than (aRR, 1.05; 95% CI, 1.01-1.08) and greater than (aRR, 1.09; 95% CI, 1.08-1.10) guidelines, and placental abruption (aRR, 1.19; 95% CI, 1.05-1.36). The pattern of results was similar when defining prenatal cannabis use only by self-report or only by toxicology testing, and associations between the frequency of prenatal cannabis use and outcomes varied with outcome. Conclusions and Relevance: The results of this cohort study suggest that prenatal cannabis use was associated with several adverse maternal health outcomes during pregnancy. Continued research is needed to understand whether characteristics of prenatal cannabis use (eg, dose, mode, and timing) moderate these associations.

Quantifying risk of tech-driven disparities.

PURPOSE: New technologies are continuously emerging in radiation oncology. Inherent technological limitations can result in healthcare disparities in vulnerable patient populations. These limitations must be considered for existing and new technologies in the clinic to provide equitable care. MATERIALS AND METHODS: We created a health disparity risk assessment metric inspired by failure mode and effects analysis (FMEA). We provide sample patient populations and their potential associated disparities, guidelines for clinics and vendors, and example applications of the methodology. RESULTS: A disparity risk priority number (dRPN) can be calculated from the product of three quantifiable metrics: the percent of patients impacted (P), the severity of the impact of dosimetric uncertainty or quality of the radiation plan (S), and the clinical dependence on the evaluated technology (C). The dRPN can be used to rank the risk of sub-optimal care due to technical limitations when comparing technologies and to plan interventions when technology is shown to have inequitable performance in the patient population of a clinic. CONCLUSION: The proposed methodology may simplify the evaluation of how new technology impacts vulnerable populations, help clinics quantify the limitations of their technological resources, and plan appropriate interventions to improve equity in radiation treatments.

Evaluation of an Embedded Health Psychologist Intervention for Obstetric Patients With Adverse Childhood Experiences.

BACKGROUND: Screening for adverse childhood experiences (ACEs) and resilience in pregnancy is a promising practice for mitigating ACEs-related health complications. Yet, the best follow-up for pregnant patients with high ACEs and/or low resilience has not been established. OBJECTIVE: This study evaluates referrals to and participation in an embedded health psychologist (EHP) intervention for pregnant patients with ACEs and/or low resilience. MATERIALS AND METHODS: Patients in 3 Kaiser Permanente Northern California medical centers with ACEs who had also received resilience screening during standard prenatal care and who were participating in an EHP intervention were included (N = 910). The authors used multivariable logistic regression to examine whether ACEs (0, 1-2, 3+) and resilience (high vs low) were associated with referrals to and participation in EHP intervention. They also evaluated the impact of EHP intervention through clinician (N = 53) and patient (N = 51) surveys. RESULTS: Patients with 3+ vs 0 ACEs were more likely to receive an EHP referral (adjusted odds ratio [aOR] = 2.89, 95% confidence interval [CI]: 1.93-4.33) and were more likely to participate in EHP intervention (aOR = 2.85, 95% CI: 1.87-4.36). Those with low vs high resilience were also more likely to receive an EHP referral (aOR = 1.86, 95% CI: 1.32-2.62) and participate in EHP (aOR = 1.71, 95% CI: 1.19-2.44). When ACEs and resilience were combined, those with high ACEs and low resilience had the greatest odds of referrals and participation. Patients and clinicians reported positive experiences with EHP intervention. CONCLUSION: Patients with higher ACEs and lower resilience scores were more likely to be referred to and participate in EHP intervention, suggesting that at-risk patients can be successfully linked with a health psychologist when accessible within obstetric care.

Representativeness of Patients With Lung Cancer in an Integrated Health Care Delivery System.

INTRODUCTION: Observational research is important for understanding the real-world benefits of advancements in lung cancer care. Integrated health care systems, such as Kaiser Permanente Northern California, have extensive electronic health records suitable for such research, but the generalizability of their populations is often questioned. METHODS: Leveraging data from the California Cancer Registry, the authors compared distributions of demographic and clinical characteristics, in addition to neighborhood and environmental conditions, between patients diagnosed with lung cancer from 2015 through 2019 at Kaiser Permanente Northern California, National Cancer Institute-designated cancer centers (NCICCs), and all other non-NCICC hospitals within the same catchment area. RESULTS: Of 20,178 included patients, 30% were from Kaiser Permanente Northern California, 8% from NCICCs, and 62% from other non-NCICC hospitals. Compared to NCICC patients, Kaiser Permanente Northern California patients were more similar to other non-NCICC patients on most characteristics. Compared to other non-NCICC patients, Kaiser Permanente Northern California patients were slightly older, more likely to be female, and less likely to be Hispanic or Asian/Pacific Islander and to reside in lower socioeconomic status (SES) neighborhoods. In contrast, NCICC patients were younger, less likely to be female or from non-Asian/Pacific Islander minoritized racial groups, and more likely to present with early-stage disease and adenocarcinoma and to reside in neighborhoods with higher SES and lower air pollution than Kaiser Permanente Northern California or other non-NCICC patients. DISCUSSION: Patients from Kaiser Permanente Northern California, compared to NCICCs, are more broadly representative of the underlying patient population with lung cancer. CONCLUSION: Research using electronic health record data from integrated health care systems can contribute generalizable real-world evidence to benchmark and improve lung cancer care.

Investigating the reproductive strategies of Deuterocohnia meziana (Bromeliaceae), an endangered and restricted species from South American rocky outcrops.

Studies of reproductive biology and resources availability to floral visitors by plant species are important to understand the plant-pollinator interactions that drive species adaptation. We aim to understand the relationship between reproduction mechanisms of Deuterocohnia meziana (Bromeliaceae) and pollinators. The species occurs in Bolivia and Paraguay, and it is the only species of the genus found in Brazil, where it is restricted to ironstone outcrops. These areas are currently threatened by the iron mining industry. Additionally, they face risks from fire occurrence and grazing by cattle. We analyzed the floral biology, reproductive system, phenology, and pollination ecology of a natural population of Deuterocohnia meziana, from ironstone outcrops in Brazil. The species exhibits diurnal anthesis, with stigma receptive throughout anthesis, and 77% of pollen viability. Deuterocohnia meziana produces relatively large amounts of nectar, especially early in the morning (32.8 ± 9.4 µl), with a mean sugar concentration of 23.5 (± 3.2) ºBrix. It is self-incompatible with a peak flowering occurring in August (dry season), although flowers are observed continuously throughout the year. The species exhibits two types of inflorescences, young and mature, among which an average of 13.1 and 3.6 flowers open per day, respectively. Hummingbirds and bees are the effective pollinators, although butterflies and ants also visit D. meziana flowers. The species is reliant on exogenous pollen and pollinators for fruit set. The continuous conservation of D. meziana populations and their communities is essential for preserving plant-pollinator mutualism and the floral community adapted to ironstone outcrops.

Antibiotic use among extremely low birth-weight infants from 2009 to 2021: a retrospective observational study.

OBJECTIVE: To assess trends in antibiotic use across a large cohort of extremely low birth-weight (<1000 g; ELBW) infants admitted to academic and community neonatal intensive care units (NICUs) across the USA over a 13-year period. DESIGN: Repeated cross-sectional cohort study. SETTING: Premier Health Database, a comprehensive administrative database of inpatient encounters from academic and community hospitals across the US. PATIENTS: ELBW inborn infants admitted to NICUs from 1 January 2009 to 31 December 2021. INTERVENTIONS: N/A MAIN OUTCOME MEASURES: Absolute and relative changes in (1) proportion of ELBW infants with antibiotic exposure and (2) days of therapy (DOT) per 1000 patient days, over time. Average annual differences were estimated using generalised linear regression with 95% CI. Disposition trends were also measured. RESULTS: Among 36 701 infants admitted to 402 NICUs, the proportion exposed to antibiotics was essentially unchanged (89.9% in 2009 to 89.3% in 2021; absolute reduction of -0.6%); generalised linear regression estimated an annual absolute difference of -0.3% (95% CI (-0.6%) to (-0.07%); p=0.01). DOT per 1000 patient days decreased from 337 in 2009 to 210 in 2021, a 37.8% relative difference and annual relative difference of -4.3% ((-5.2%) to (-3.5%); p<0.001). Mortality was unchanged during the study period. CONCLUSIONS: We found a substantial reduction in antibiotic DOT despite no substantive change in the proportion of infants exposed to antibiotics. This suggests the success of stewardship efforts aimed at antibiotic duration and highlight the need for improved approaches to identifying ELBW infants at highest risk of infection.

Trends in analgesia-sedation of pediatric patients receiving I-131 MIBG in the pediatric intensive care unit: A report from the Pediatric Health Information System database.

BACKGROUND: Children with neuroblastoma receiving I-131 metaiodobenzylguanidine (MIBG) therapy require sedation-analgesia for strict radiation safety precautions during MIBG infusion and clearance. We evaluated the sedation-analgesia trends of patients undergoing MIBG therapy using the Pediatric Health Information System (PHIS) database. MATERIALS AND METHODS: Retrospective data from 476 patient encounters from the PHIS from 2010 to 2019. RESULTS: Total 240/476 (50.45%) children evaluated were under 6 years of age. Compared to 2010, in 2018 there was a decrease in benzodiazepine infusion use (60% vs. 40%, p < .04), as well as a decrease in use of opiate infusion (35% vs. 25%, p < .001). Compared to 2010, in 2018 we report an increase in the use of ketamine (from 5% to 10%, p < .002), as well as an increase in dexmedetomidine use (0% vs. 30%, p < .001). Dexmedetomidine was the most used medication in the 0-3 years age group compared to children older than 3 years of age (14.19% vs. 5.80%, p < .001). Opiate was the most used medication in children greater than 3 years compared to the 0-3-year age group (36.23 vs. 23.87, p < .05). CONCLUSION: Using PHIS data, we discovered considerable variability in the medications used for sedation in patients undergoing MIBG therapy. Although benzodiazepines and opioids were the most used agents, there was a trend toward decreasing use of benzodiazepines and opioids in these patients. Furthermore, there has been an increasing trend in the use of dexmedetomidine and ketamine.

Prevalence, diagnostic features, and medical outcomes of females with Turner syndrome with a trisomy X cell line (45,X/47,XXX): Results from the InsighTS Registry.

Turner syndrome (TS) is defined by partial or complete absence of a sex chromosome. Little is known about the phenotype of individuals with TS mosaic with trisomy X (45,X/47,XXX or 45,X/46,XX/47,XXX) (~3% of TS). We compared the diagnostic, perinatal, medical, and neurodevelopmental comorbidities of mosaic 45,X/47,XXX (n = 35, 9.4%) with nonmosaic 45,X (n = 142) and mosaic 45,X/46,XX (n = 66). Females with 45,X/47,XXX had fewer neonatal concerns and lower prevalence of several TS-related diagnoses compared with 45,X; however the prevalence of neurodevelopmental and psychiatric diagnoses were not different. Compared to females with 45,X/46,XX, the 45,X/47,XXX group was significantly more likely to have structural renal anomalies (18% vs. 3%; p = 0.03). They were twice as likely to have congenital heart disease (32% vs. 15%, p = 0.08) and less likely to experience spontaneous menarche (46% vs. 75% of those over age 10, p = 0.06), although not statistically significant. Congenital anomalies, hypertension, and hearing loss were primarily attributable to a higher proportion of 45,X cells, while preserved ovarian function was most associated with a higher proportion of 46,XX cells. In this large TS cohort, 45,X/47,XXX was more common than previously reported, individuals were phenotypically less affected than those with 45,X, but did have trends for several more TS-related diagnoses than individuals with 45,X/46,XX.

Interhospital Transfer of Patients With Acute Respiratory Failure in the United States: A Scoping Review.

OBJECTIVES: Interhospital transfer of patients with acute respiratory failure (ARF) is relevant in the current landscape of critical care delivery. However, current transfer practices for patients with ARF are highly variable, poorly formalized, and lack evidence. We aim to synthesize the existing evidence, identify knowledge gaps, and highlight persisting questions related to interhospital transfer of patients with ARF. DATA SOURCES: Ovid Medline, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Embase, CINAHL Plus, and American Psychological Association. STUDY SELECTION: We included studies that evaluated or described hospital transfers of adult (age > 18) patients with ARF between January 2020 and 2024 conducted in the United States. Using predetermined search terms and strategies, a total of 3369 articles were found across all databases. After deduplication, 1748 abstracts were screened by authors with 45 articles that advanced to full-text review. This yielded 16 studies that fit our inclusion criteria. DATA EXTRACTION: The studies were reviewed in accordance to Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews by three authors. DATA SYNTHESIS: Included studies were mostly retrospective analyses of heterogeneous patients with various etiologies and severity of ARF. Overall, transferred patients were younger, had high severity of illness, and were more likely to have commercial insurance compared with nontransferred cohorts. There is a paucity of data examining why patients get transferred. Studies that retrospectively evaluated outcomes between transferred and nontransferred cohorts found no differences in mortality, although transferred patients have a longer length of stay. There is limited evidence to suggest that patients transferred early in their course have improved outcomes. CONCLUSIONS: Our scoping review highlights the sparse evidence and the urgent need for further research into understanding the complexity behind ARF transfers. Future studies should focus on defining best practices to inform clinical decision-making and improve downstream outcomes.

Individuals with Cleft Lip and/or Palate Demonstrated Improved Self-Reported Psychosocial Functioning Following the Onset of the COVID-19 Pandemic.

Objective: To evaluate the impact of the COVID-19 pandemic on the psychosocial functioning of individuals with cleft lip and/or palate (CL/P). Methods: Patients with CL/P ≥ 6 years old were prospectively recruited from the Cleft and Craniofacial Clinic of a tertiary children's hospital. From July-October 2021, eligible patients (or their parent/guardian) were sent a survey regarding their psychosocial functioning before and after the start of the pandemic. Main Outcome Measure: The difference between prepandemic and intrapandemic patient-reported outcome scores. Results: Thirty-six patients (20 female, age: 15.9 ± 9.8 years) responded. Most had cleft lip and palate (77.8%), responded online (69.4%), interacted remotely via both voice- and video-conferencing (62.9%), and wore masks routinely (77.1%). Similar numbers of patients responded independently (27.8%), responded with the help of a parent/guardian (36.1%), or had a parent/guardian respond on their behalf (36.1%). General social-emotional well-being (p = 0.004, r rb = 0.659) and satisfaction with facial appearance (p = 0.044, r rb = 0.610) significantly improved after the start of the pandemic. Compared to their general intrapandemic social-emotional well-being scores, patients reported higher scores while wearing a mask (r rb = 0.827) and lower scores while interacting remotely (r rb = 0.605), although all were still significantly improved compared to their prepandemic scores (p ≤ 0.010). Patients also reported significant improvement in social functioning while wearing a mask (p = 0.036, r rb = 0.519), whereas they did not when considering their general intrapandemic feelings/experiences (p = 0.269, r rb = 0.211). Conclusion: Patients with CL/P demonstrated significant improvement in overall social-emotional well-being, satisfaction with facial appearance, and social functioning after the start of the COVID-19 pandemic, particularly when wearing a mask.

Staying in the Game: Interventions for Managing Achilles Tendinopathy in the In-Season Athlete.

ABSTRACT: Achilles tendinopathy is a common overuse injury that is traditionally managed with activity modification and a progressive eccentric strengthening program. This narrative review describes the available evidence for adjunctive procedural interventions in the management of midportion and insertional AT, specifically in the athletic population. Safety and efficacy data from available literature on extracorporeal shockwave therapy, platelet-rich plasma, high-volume injectate with or without tendon scraping, and percutaneous needle tenotomy are used to propose an algorithm for treatment of Achilles tendinopathy for the in-season athlete.

Transcatheter PFO closure for cryptogenic stroke: current approaches and future considerations.

Patent Foramen Ovale (PFO) is a common congenital atrial septal defect present in 20%-35% of the general population. Although generally considered a benign anatomic variant, a PFO may facilitate passage of a thrombus from the venous to arterial circulation, thereby resulting in cryptogenic stroke or systemic embolization. A PFO is detected in nearly one half of patients presenting with cryptogenic stroke and often considered the most likely etiology when other causes have been excluded. In this review, we discuss the contemporary role of transcatheter closure of PFO in the treatment of cryptogenic stroke, including devices currently available for commercial use in the United States (Amplatzer PFOTM Occluder and GoreTM Cardioform Septal Occluder) and a novel suture-mediated device (NobleStitchTM EL) under clinical investigation. To provide the best care for cryptogenic stroke patients, practitioners should be familiar with the indications for PFO closure and corresponding treatment options.

Postdiscontinuation Antibiotic Exposure in Hospitalized Infants at Risk for Late-onset Sepsis in the Neonatal Intensive Care Unit.

BACKGROUND: In the neonatal intensive care unit, infants are at risk for late-onset sepsis. When blood cultures are negative, antibiotic stewardship efforts encourage stopping antibiotics, yet the duration of therapeutic exposure after the last dose is unknown. METHODS: This retrospective cohort study of simulated antibiotic exposures used published population pharmacokinetic models within drug-specific neonatal intensive care unit cohorts of preterm and term infants, postnatal age 7-60 days and exposed to cefepime, piperacillin-tazobactam or tobramycin. Monte Carlo simulations (NONMEM 7.3) were used to predict steady-state exposures after a 72-hour antibiotic course per Neofax dosing. Exposure was assessed relative to drug-specific minimum inhibitory concentration (MIC) targets between 1 and 16 mcg/mL for Pseudomonas and Enterobacteriaceae species. Postdiscontinuation antibiotic exposure (PDAE) was defined as the time from the last dose to when antibiotic concentration decreased below a specific MIC. RESULTS: Piperacillin-tazobactam, cefepime and tobramycin cohorts included infants with median gestation age 29, 32 and 32 weeks and postnatal age 17, 19 and 15 days, respectively. The mean PDAE was 19-68 hours, depending on the specific antibiotic/MIC combination. PDAE was longer for infants <28 days old and preterm (vs. term) infants. Cefepime exhibited the longest mean PDAE of 68 hours for Enterobacteriaceae MIC 1. Piperacillin mean PDAE was 25 hours for Enterobacteriaceae MIC 8. Tobramycin had a short mean PDAE of 19 hours. CONCLUSIONS: Piperacillin and cefepime exposures remained therapeutic long after the expected 8- to 12-hour dosing interval. PDAE is an important consideration for antibiotic stewardship among hospitalized infants, particularly premature infants and those within 1 month postbirth.

Why dental schools should engage with dental support organizations.

It is incumbent on dental educators to prepare students for careers in various practice settings and modalities. As the dental practice market continues to evolve away from a predominantly solo private practice model, schools are tasked with training future providers to deliver quality care to diverse patient populations in diverse settings. While no single health delivery model will solve access to care, exposing dental students to various practice environments prepares them to better understand and navigate nontraditional postgraduate practice opportunities. The University of California, Los Angeles (UCLA) School of Dentistry established a community-based clinical education (CBCE) program that has grown to include dental support organizations. By partnering with a more diverse portfolio of practice types, including large corporate entities, the UCLA CBCE program has strengthened its financial accountability while also delivering on the goal of enhancing dental education and improving access to care for vulnerable populations.

The role of psychiatric symptoms, sociodemographic factors, and baseline sleep variables on pediatric insomnia treatment outcomes in a clinically referred population.

STUDY OBJECTIVES: The current study aimed to examine clinically relevant psychiatric and sociodemographic predictors of insomnia treatment outcomes in pediatric patients clinically referred for insomnia. METHODS: Pediatric patients (N = 1428; ages 1.5 - 18 years), presenting for insomnia evaluation in a medical/sleep center-based behavioral sleep clinic were followed for treatment as clinically indicated. According to patient age, parent/patients completed validated measures of insomnia severity, psychiatric symptoms, and sociodemographic measures. Patients were also categorized by treatment outcome status (i.e., not recommended to follow-up after initial evaluation and treatment session, successful treatment completion, lost to follow-up after initial evaluation and treatment session, and early termination) according to the clinically indicated treatment recommended and dose of treatment received. RESULTS: Youth had elevated scores on psychiatric screening indexes with affective problems being highest for all age groups. Other co-morbid sleep disorders were present in nearly 25% of insomnia patients and use of sleep aids (melatonin; hypnotics) was commonplace. Baseline insomnia severity significantly predicted sleep treatment trajectories and post-treatment insomnia severity with large effects for all age groups. Other clinically relevant predictors of insomnia treatment outcomes included medication use and externalizing mental health concerns in younger patients and internalizing mental health concerns and chronological age in older patients. Lack of treatment follow-up and premature treatment termination was observed for patients with the worst insomnia symptoms at time of initial evaluation. CONCLUSIONS: Pediatric health providers delivering insomnia treatment should take a developmentally sensitive approach that is proactive with regards to managing treatment barriers that are likely influenced by severity of insomnia and co-morbid mental health concerns.

Palbociclib combined with endocrine treatment in hormone receptor-positive, HER2-negative breast cancer patients with high relapse risk after neoadjuvant chemotherapy: subgroup analyses of premenopausal patients in PENELOPE-B.

BACKGROUND: The PENELOPE-B study demonstrated that the addition of 1-year post-neoadjuvant palbociclib to endocrine therapy (ET) in patients with high-risk early breast cancer (BC) did not improve invasive disease-free survival (iDFS) compared to placebo. Here, we report results for premenopausal women. PATIENTS AND METHODS: Patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative BC at high risk of relapse [defined as no pathological complete response after neoadjuvant chemotherapy and a clinical, pathological stage, estrogen receptor, grading (CPS-EG) score ≥3 or 2/ypN+] were randomized to receive 13 cycles of palbociclib or placebo + standard ET. Ovarian function (OF) was evaluated by centrally assessed estradiol, follicle-stimulating hormone and anti-Müllerian hormone serum levels. RESULTS: Overall, 616 of 1250 randomized patients were premenopausal; of these, 30.0% were <40 years of age, 47.4% had four or more metastatic lymph nodes, and 58.2% had a CPS-EG score ≥3. 66.1% of patients were treated with tamoxifen alone, and 32.9% received ovarian function suppression (OFS) in addition to either tamoxifen or aromatase inhibitor (AI). After a median follow-up of 42.8 months (97.2% completeness) no difference in iDFS between palbociclib and placebo was observed [hazard ratio = 0.95, 95% confidence interval (CI) 0.69-1.30, P = 0.737]. The estimated 3-year iDFS rate was marginally higher in the palbociclib arm (80.6% versus 78.3%). Three year iDFS was higher in patients receiving AI than tamoxifen plus OFS or tamoxifen alone (86.0% versus 78.6% versus 78.0%). Patients receiving tamoxifen plus OFS showed a favorable iDFS with palbociclib (83.0% versus 74.1%, hazard ratio = 0.52, 95% CI 0.27-1.02, P = 0.057). Hematologic adverse events were more frequent with palbociclib (76.1% versus 1.9% grade 3-4, P < 0.001). Palbociclib seems not to negatively impact the OF throughout the treatment period. CONCLUSIONS: In premenopausal women, who received tamoxifen plus OFS as ET, the addition of palbociclib to ET results in a favorable iDFS. The safety profile seems favorable and in contrast to chemotherapy palbociclib does not impact OF throughout the treatment period.

Associations between Intake of Dietary Sugars and Diet Quality: A Systematic Review of Recent Literature.

Understanding the relationship between the intake of sugars and diet quality can inform public health recommendations. This systematic review synthesized recent literature on associations between sugar intake and diet quality in generally healthy populations aged 2 years or older. We searched databases from 2010 to 2022 for studies of any design examining associations between quantified sugar intake in the daily diet and dietary indexes (DIs) or micronutrient intakes. Different sugar types and diet quality measures were analyzed separately. We converted DI results to Pearson's r correlations and grouped indexes with or without a free or added sugar component to facilitate cross-study comparisons. Meta-analysis was deemed inappropriate. From 13,869 screened records, we included 27 cross-sectional studies. NUQUEST risk of bias ratings were neutral (n = 18 studies) or poor (n = 9), and strength of evidence by the GRADE approach was very low due to study design. Most studies reported negative associations for added and free sugars with diet quality indexes (r ranging from -0.13 to -0.42) and nutrients of public health concern (fiber, vitamin D, calcium, potassium), while associations with total sugars were mixed. Due to cross-sectional study designs, the clinical relevance of these findings is unclear. Prospective studies are needed to minimize confounding and inform causal relationships.

Leadership Experiences and Perceptions of Mid-Career to Senior Clinician-Scientists: A Qualitative Exploration.

PURPOSE: This study aimed to elucidate the experiences and perceptions of mid-career to senior clinician-scientists in academic medicine regarding pursuing, attaining, or rejecting leadership roles as well as their conceptualization of the influence of leadership in their broader career trajectories. METHOD: The authors conducted a qualitative analysis of in-depth, semistructured interviews conducted in 2022 with a diverse sample of clinician-scientists who received new National Institutes of Health K08 or K23 Career Development Awards between 2006 and 2009. A total of 859 of the 915 survey respondents (94%) were eligible to be recruited for the qualitative study. Qualitative analysis was informed by thematic analysis and used a social constructionist approach to understanding participants' conceptualizations of their experiences. Interview transcripts were coded using an iterative, inductive coding process. Themes were generated by reviewing coded data and identifying common patterns in participant narratives, affording particular attention to participants' discussion of the effect of race and/or gender on their leadership experiences. RESULTS: Sixty clinician-scientists participated in individual interviews. Five themes were generated surrounding participants' conceptualizations of their leadership experiences. Themes were (1) feeling unprepared for leadership roles, (2) reluctance and lack of intention in attaining leadership positions, (3) influence of networks on leadership access and decision-making, (4) impact-related benefits and downsides of leadership, and (5) confining ideas of who leaders are. CONCLUSIONS: The study highlighted the need for formal leadership training in academic medicine and the importance of mentorship and sponsorship in attaining and succeeding in leadership positions. Individuals from communities underrepresented in leadership positions faced additional challenges internalizing a leadership identity. Efforts to encourage current leaders to engage in intentional succession planning and development of faculty towards leadership roles, including expansion of institutional leadership development programs, are needed to promote equitable distribution of leadership opportunities.

Burnout Among Mid-Career Academic Medical Faculty.

Importance: Studies reveal that most physicians report symptoms of burnout. Less is known about burnout in mid-career medical faculty specifically. Objective: To characterize burnout and its risk factors, particularly differences by gender, among mid-career medical faculty. Design, Setting, and Participants: Between August 2021 and August 2022, a survey was sent to 1430 individuals who received new National Institutes of Health K08 and K23 career development awards from 2006 to 2009. Data were analyzed between June and October 2023. Main Outcomes and Measures: Personal and work-related burnout as evaluated using the Copenhagen Burnout Inventory (CBI). The CBI score ranges from 0 to 100, with a score of 50 or higher indicating a high degree of burnout. Multivariable models were used to investigate associations between burnout and participant characteristics, including race and ethnicity, sexual orientation and gender identity, academic rank, work climate, experiences of workplace sexual harassment, sleep hours, work and domestic caregiving time, and time allocation changes in work and domestic work hours compared with before the COVID-19 pandemic. Work climate was evaluated by a general climate elements scale assessing elements such as friendliness, respect, and collegiality, and a diversity, equity, and inclusion climate elements scale assessing elements such as homogeneity, sexism, and homophobia; higher scores indicated a more favorable view of the climate. Results: In all, 1430 surveys were sent, 926 candidates responded (65% response rate), and the analytic cohort was limited to the 841 respondents who were still in academic medicine (50.7% men). Burnout was significantly more common for women than men (mean [SD] CBI personal scores, 46.6 [19.4] vs 37.5 [17.2]; P < .001; mean [SD] CBI work-related scores, 43.7 [20.4] vs 34.6 [19.7]; P < .001). In multivariable models, personal burnout was significantly more likely for women (adjusted odds ratio [AOR], 2.29 [95% CI, 1.54-3.41]; P < .001) and with more weekly hours of patient care (AOR, 1.07 [95% CI, 1.00-1.15] for each 5-hour increase; P = .04). Personal burnout was less likely with more nightly sleep hours (AOR, 0.68 [95% CI, 0.56-0.81] for each 1-hour increase; P < .001) and with an improved general work climate rating (AOR, 0.64 [95% CI, 0.48-0.85] for each 1-point increase in general work climate scale score; P = .002). Work-related burnout was also significantly more likely for women than men (AOR, 1.77 [95% CI, 1.17-2.69]; P = .007). Greater work-related burnout was associated with an increase of 8 or more work hours per week compared with before the COVID-19 pandemic (AOR, 1.87 [95% CI, 1.13-3.08]; P = .01), more weekly hours of patient care (AOR, 1.11 [95% CI, 1.03-1.19] for each 5-hour increase; P = .007), and a workplace sexual harassment experience in the past 2 years (AOR, 1.71 [95% CI, 1.11-2.62]; P = .01). Work-related burnout was significantly less likely with more nightly sleep hours (AOR, 0.80 [95% CI, 0.66-0.96] for each 1-hour increase; P = .02) and with an improved general work climate rating (AOR, 0.49; [95% CI, 0.36-0.65] for each 1-point increase in general work climate scale score; P < .001). Conclusions and Relevance: This survey study of K grant awardees revealed substantial rates of burnout among mid-career medical faculty, and burnout rates differed by gender. Evidence-based interventions are needed to realize the benefits of workforce diversity and vitality.

Retrospective operationalization of allostatic load in patients with cancer: A systematic review.

Allostatic load (AL) has been shown to impact cancer outcomes. At present, no gold standard exists surrounding AL computation. As such, a systematic review of the literature was performed to identify studies that retrospectively calculated AL in patients with cancer. The following variables were collected for each study: AL calculation method, including the biomarkers used and their cutoff values, number of biosystems represented, definition of high AL, and the use of proxy biomarkers. Thirteen articles were included for full-text review. The number of biomarkers used in the calculation of AL varied considerably, ranging from 6 to 16. Considerable variability was also observed in terms of utilized biomarkers and biosystem representation. This lack of standardization complicates retrospective AL calculation among patients with cancer. Nonetheless, determining AL in patients with cancer presents an important step in the optimization of patient care and outcomes.
