RESUMEN

BACKGROUND: The clinical value of serial routine bone marrow aspirates (rBMAs) in the first year after allogeneic hematopoietic cell transplantation (alloHCT) to detect or predict relapse of acute leukemia (AL) and myelodysplastic syndrome (MDS) in pediatric and young adult patients is unclear. OBJECTIVE: The purpose of this analysis was to determine if assessment of minimal residual disease (MRD) by multiparameter flow cytometry (MFC, MFC-MRD) or donor chimerism (DC) in rBMAs or serial CBCs done in the year after alloHCT predicted relapse of AL or MDS in pediatric and young adult patients. STUDY DESIGN: We completed a retrospective analysis of patients with AL or MDS who had rBMAs performed after alloHCT between January 2012- June 2018. Bone marrow (BM) was evaluated at approximately 3, 6 and 12 months for disease recurrence by morphology, MFC-MRD and percent DC by short tandem repeat (STR) molecular testing. CBCs were performed at every clinic visit. The main outcome of interest was assessment of whether MFC-MRD or DC in rBMAs or serial CBCs done in the year after alloHCT predicted relapse in AL or MDS pediatric and young adult patients. RESULTS: 121 recipients with median age of 13 years (range 1-31) were included: 108 with AL and, 13 with MDS. A total of 423 rBMAs (median 3; 0 - 13) were performed. Relapse at 2 years was 23% (95%CI:16 - 31%) and at 5 years 25% (95%CI 18-33%). 154 of 157 (98%) rBMAs evaluated for MRD by MFC were negative and did not preclude subsequent relapse. Additionally, low DC (< 95%) did not predict relapse and high DC (≥ 95%) did not preclude relapse. For patients alive without relapse at 1 year, BM DC (p = 0.74) and peripheral T-cell DC (p = 0.93) did not predict relapse. Six patients with low level T-cell and/or BM DC had a total of 8-20 BM evaluations, none of these patients relapsed. However, CBC results were informative for relapse; 28 of 31 (90%) relapse patients presented with an abnormal CBC with peripheral blood (PB) blasts (16 patients), cytopenias (9 patients), or extramedullary disease (EMD, 3 patients). Two patients with BM blasts >5% on rBMA had circulating blasts within 5 weeks of rBMA. Neutropenia (ANC <1.5 K/mcl) at 1 year was predictive of relapse (p= 0.01). Neutropenia and thrombocytopenia (<160K/mcl) were predictive of diseases free survival (DFS) with inferior DFS for ANC<1.5 K/mcl; p = 0.001, or platelet count <160K/mcl (p = 0.04). CONCLUSION: These results demonstrate rBMAs after alloHCT assessed for MRD by MFC and/or for level of DC are poor predictors for relapse in pediatric and young adult patients with AL or MDS. Relapse in these patients presents with PB blasts, cytopenias or EMD. ANC and platelet count at 1-year were highly predictive for DFS.

RESUMEN

Wolves are assumed to be ungulate obligates, however, a recently described pack on Pleasant Island, Alaska USA, is persisting on sea otters and other marine resources without ungulate prey, violating this long-held assumption. We address questions about these wolves regarding their origin and fate, degree of isolation, risk of inbreeding depression, and diet specialization by individual and sex. We applied DNA metabarcoding and genotyping by amplicon sequencing using 957 scats collected from 2016 to 2022, and reduced representation sequencing of tissue samples to establish a detailed understanding of Pleasant Island wolf ecology and compare them with adjacent mainland wolves. Dietary overlap was higher among individual wolves on Pleasant Island (Pianka's index mean 0.95 ± 0.03) compared to mainland wolves (0.70 ± 0.21). The individual diets of island wolves were dominated by sea otter, ranging from 40.6% to 63.2% weighted percent of occurrence (wPOO) (mean 55.5 ± 8.7). In contrast, individual mainland wolves primarily fed on ungulates (42.2 ± 21.3) or voles during a population outbreak (31.2 ± 23.2). We traced the origin of the Pleasant Island pack to a mainland pair that colonized around 2013 and produced several litters. After this breeding pair was killed, their female offspring and an immigrant male became the new breeders in 2019. We detected 20 individuals of which 8 (40%) were trapped and killed while two died of natural causes during the 6-year study. Except for the new breeding male, the pedigree analysis and genotype results showed no additional movement to or from the island, indicating limited dispersal but no evidence of inbreeding. Our findings suggest wolves exhibit more flexible foraging behavior than previously believed, and hunting strategies can substantially differ between individuals within or between packs. Nevertheless, anthropogenic and natural mortality combined with limited connectivity to the mainland may inhibit the continued persistence of Pleasant Island wolves.

RESUMEN

Background: Dysphoric milk ejection reflex (D-MER) is a phenomenon that occurs before milk letdown and is described as a wave of negative or devastating emotions, ranging from mild to severe and lasting for seconds to minutes. To date, there has been little research regarding this phenomenon. This study aims to determine the prevalence of D-MER in our population as well as its association with postnatal depression scores and breastfeeding self-efficacy. Methods: Lactating persons between 4 and 12 weeks postpartum at our institution were invited to complete an anonymous 59-question survey via an online platform. Questions asked included patient demographics, presence of symptoms of dysphoria (including timing, duration, and frequency), the Edinburgh Postnatal Depression Scale (EPDS), and the Breastfeeding Self-Efficacy Scale Short Form (BSES-sf). Results: In total, 201 women completed the survey. Twelve women were classified as likely having D-MER (6%). Symptom resolution primarily occurred within a minute to 5 minutes (58%). Mean EPDS scores differed significantly between those with likely D-MER and those without (12.2 vs. 5.4, p = 0.002). BSES-sf scores differed significantly between the two groups (43.1 vs. 52.5, p = 0.009). Preexisting depression or anxiety was not associated with D-MER (p = 0.133), other reported mood disorders differed significantly between those with D-MER and those without (p = 0.004). Demographic characteristics of women with and without D-MER were similar. Conclusion: D-MER prevalence may be lower than previously reported. Patients with likely D-MER appear to have lower breastfeeding self-efficacy and higher depression scores. Those with preexisting mood disorders may be at higher risk of experiencing D-MER.

RESUMEN

Pain is the hallmark symptom causing morbidity for people with sickle cell disease (SCD) and may present as nociceptive, neuropathic, or mixed type pain. Neuropathic pain (NP) is underrecognized and undertreated in patients with SCD and is associated with decreased patient-reported quality of life. Surveys were completed by clinicians caring for adolescents with SCD in the outpatient setting. SCD patients ages 1418 at increased risk of NP completed a patient-facing survey at a scheduled clinic visit. Ninety-four percent of responding clinicians agreed that NP significantly contributes to reported pain in SCD. Clinicians believed that NP medications are effective for reducing chronic pain (62%) and decreasing opioid utilization (44%). Clinician-identified barriers to prescribing NP medications included concerns about medication adherence (82%), lack of pediatric guidelines for NP medications (70%), and perceived patient concern about side effects (65%). More than 1/3 (35%) of clinicians reported that they were not comfortable managing NP medications. Clinician-identified barriers to referral to a pain management specialist included scheduling concerns (88%) and perceived patient/family lack of interest (77%). Most patients expressed willingness to take a medication for NP (78%), see a pain management specialist (84%), or learn more about nonpharmacologic interventions (72%), although most (51%) also reported some concerns about taking a medication for NP, citing insufficient knowledge (34%), and potential for side effects (32%). A minority of respondents (15%) worried about referral to a pain management specialist. Clinician and patient perspectives provide insights that may guide education efforts or other interventions to improve treatment of SCD-related NP.

RESUMEN

With considerable debate concerning the impact of culture on the expression of callous-unemotional (CU) traits, it is unclear whether the core features of CU traits generalize to youth across cultures. This study aimed to examine whether cultural differences are reflected in the core features of CU traits and the associations among these features. Network analysis was employed to identify the core features and to examine the network structure of CU traits operationalized by the Inventory of Callous Unemotional traits (ICU) in four community youth samples from different nations (Australia, N = 190; the UK, N = 437; the USA, N = 330; China, N = 503). The item "Apologizes to people" was identified as a cross-cultural core feature in the ICU network with a greater centrality of this item compared to others in all four samples. In addition, some items were identified as culture-specific core features in the network, differing in their centrality across samples. The network structures of the youth self-report ICU items were moderately similar across samples, while the structures of parent-report items showed substantial differences. These findings have important implications for cross-cultural research on CU traits as well as practical implications for screening and treatment. The core features of ICU appear to be generalizable in youth across cultures, although cultural-specific manifestations should be noted.

RESUMEN

OBJECTIVE: To quantify the association between attributional ambiguity-the uncertainty of whether an experience is discrimination-and mental health. METHODS: Using a nationally representative sample of U.S. adults recruited through an online survey by Ipsos (April 23 and May 3, 2021), attributional ambiguity was quantified by asking participants if they experienced anything in the past 6 months that they were unsure was discrimination. The survey also assessed the degree to which these experiences caused participants to feel bothered and to ruminate on them. Multiple linear regression models were used to analyze associations between attributional ambiguity and depressive symptoms and mental health status. RESULTS: Black and Hispanic participants reported higher rates of attributional ambiguity than White participants. Experiencing attributional ambiguity was associated with higher levels of depressive symptoms and poorer self-reported mental health status. Among those who reported attributional ambiguity, increases in bother and rumination scores were positively associated with depressive symptoms. CONCLUSION: Attributional ambiguity is an important yet overlooked social determinant of mental health. More research is needed to fully understand the impact of this stressor on population health, particularly among minoritized populations.

RESUMEN

Long COVID and its symptoms have not been examined in different subpopulations of U.S. adults. Using the 2022 BRFSS (n = 445,132), we assessed long COVID and each symptom by sociodemographic characteristics and health-related variables. Multivariable logistic regression was conducted to examine factors associated with long COVID and the individual symptoms. Prevalence differences were conducted to examine differences in long COVID by vaccination status. Overall, more than one in five adults who ever had COVID-19 reported symptoms consistent with long COVID (21.8%). The most common symptom was tiredness or fatigue (26.2%), followed by difficulty breathing or shortness of breath (18.9%), and loss of taste or smell (17.0%). Long COVID was more common among adults under 65 years, women, American Indian or Alaska Native or other/multi race group, smokers, and people with a disability, depression, overweight or obesity compared to their respective counterparts. The prevalence of long COVID was higher among unvaccinated adults (25.6%) than vaccinated adults (21.6%) overall, and for 20 of 32 subgroups assessed. These findings underscore the benefits of vaccination, the importance of early treatment, and the need to better inform health care resource allocation and support services for those experiencing long COVID.

RESUMEN

Atypical responses to teacher rewards, discipline and different forms of instructional methods have been identified as potential contributors to disruptive behavior, low school engagement, and academic underachievement in children with elevated callous-unemotional (CU) traits. To date, research on CU traits in schools has relied on interview or questionnaire methods and has predominantly been conducted in Western countries. Thus, the present study aims to investigate the relationships between CU traits and children's responses to teacher rewards, discipline and instructional methods in the Chinese preschool context using classroom observation. Eight teachers (7 females, 1 male; M = 37.66 years) and 116 children (56% girls; M = 5.16 years) from two mainstream Chinese preschools participated in the study. Of the 116 eligible children, the behavior of 108 children from four classes were observed during classroom activities. Findings indicated that CU traits were not related to children's responses to discipline, nor did CU traits moderate the relationship between instructional methods and children's academic engagement. Higher CU traits predicted a greater frequency of one-to-one teacher-child interaction. Our findings offer initial insights into the potential of early school-based interventions in fostering engagement and prosocial behavior among children with CU traits. However, they also highlight the need for additional support for preschool teachers, who face the challenge of managing these high-risk children who appear to require more individual time and attention.

RESUMEN

Identifying successful approaches for reducing the belief and spread of online misinformation is of great importance. Social media companies currently rely largely on professional fact-checking as their primary mechanism for identifying falsehoods. However, professional fact-checking has notable limitations regarding coverage and speed. In this article, we summarize research suggesting that the "wisdom of crowds" can be harnessed successfully to help identify misinformation at scale. Despite potential concerns about the abilities of laypeople to assess information quality, recent evidence demonstrates that aggregating judgments of groups of laypeople, or crowds, can effectively identify low-quality news sources and inaccurate news posts: Crowd ratings are strongly correlated with fact-checker ratings across a variety of studies using different designs, stimulus sets, and subject pools. We connect these experimental findings with recent attempts to deploy crowdsourced fact-checking in the field, and we close with recommendations and future directions for translating crowdsourced ratings into effective interventions.

RESUMEN

Chromosomal instability (CIN) is a hallmark of cancer, caused by persistent errors in chromosome segregation during mitosis. Aggressive cancers like high-grade serous ovarian cancer (HGSOC) and triple-negative breast cancer (TNBC) have a high frequency of CIN and TP53 mutations. Here, we show that inhibitors of the KIF18A motor protein activate the mitotic checkpoint and selectively kill chromosomally unstable cancer cells. Sensitivity to KIF18A inhibition is enriched in TP53-mutant HGSOC and TNBC cell lines with CIN features, including in a subset of CCNE1-amplified, CDK4-CDK6-inhibitor-resistant and BRCA1-altered cell line models. Our KIF18A inhibitors have minimal detrimental effects on human bone marrow cells in culture, distinct from other anti-mitotic agents. In mice, inhibition of KIF18A leads to robust anti-cancer effects with tumor regression observed in human HGSOC and TNBC models at well-tolerated doses. Collectively, our results provide a rational therapeutic strategy for selective targeting of CIN cancers via KIF18A inhibition.

RESUMEN

A perimenopausal woman with abnormal uterine bleeding underwent an uncomplicated laparoscopic hysterectomy. Postoperatively, she developed fever, abdominal erythema and pain. Imaging revealed diffuse abdominal wall skin thickening, most pronounced at the right port site with a small area concerning for developing abscess. There was high clinical suspicion for necrotising fasciitis due to rapidly progressive skin deterioration. Despite antibiotics and surgical debridement, her condition progressed. Biopsy of the inflamed tissue confirmed a diagnosis of pyoderma gangrenosum (PG), and treatment with daily prednisone led to rapid improvement of symptoms.Successful diagnosis and treatment of the patient's symptoms required multidisciplinary collaboration among gynaecology, general surgery and dermatology. PG, although a well-known condition among dermatologists, is rarely, if ever, encountered by gynaecologists, and its resemblance to conditions such as necrotising fasciitis complicates early detection and intervention. This case highlights the diagnostic and management challenges associated with PG in the gynaecological setting.

RESUMEN

Contested racial identity-the discrepancy between one's self-identified race and socially assigned race-is a social determinant of health and may contribute to overweight and obesity. Obesity is associated with a host of short- and long-term health conditions, including cardiovascular disease, a leading cause of death. Individuals racialized as Black, Hispanic, and Latino are at the greatest risk of obesity. Previous research indicates that experiencing interpersonal discrimination is associated with higher body mass index (BMI) in adults, and individuals with a contested racial identity are disproportionately exposed to interpersonal discrimination. However, the association between BMI and contested racial identity is unknown. This cross-sectional study measured the relationship between contested racial identity and perceived everyday discrimination on BMI in a nationally representative sample of US adults. Contested racial identity was measured with a binary variable indicating agreement between participants' self-identified race and socially assigned race. Weighted unadjusted and adjusted multiple linear regression models quantified the associations between BMI and contested racial identity with and without the mean discrimination score. Covariates included nativity status, income, education, racial identity salience, gender, and age. Among 1689 participants, 18.3% had a contested racial identity. Contested identity was associated with significantly higher BMI (ß = 1.01, 95% CI = 0.06, 1.92), but the relationship was attenuated when adjusting for interpersonal discrimination, suggesting that individuals with contested identity may face a greater risk of obesity due to their disproportionately high exposure to interpersonal racial discrimination. Further research is needed to elucidate the impact of racism on BMI and obesity risk.

RESUMEN

OBJECTIVE: This study aimed to assess the variance in menopause education, educational resources, and the needs of obstetrics and gynecology (ObGyn) residency programs by conducting a national survey of program directors (PDs). METHODS: In 2022, an institutional review board-approved Web-based Qualtrics survey was designed and distributed electronically to 145 US ObGyn residency PDs. The survey consists of 15 questions. The main outcomes are reported using descriptive statistics. RESULTS: The survey was completed by 99 of 145 PDs (68.3%). Almost all participants (92.9%) strongly agreed that residents nationwide should have access to a standardized menopause curriculum that could be utilized in their programs. Only 31.3% reported having a menopause curriculum in their residency program. Of the programs with a menopause curriculum, 96.8% reported using lectures, 77.4% reported assigned readings, and 74.2% had either dedicated menopause clinics or other clinics with a high volume of menopausal patients. Of all programs surveyed, only 29.3% reported that trainees had dedicated time assigned to a menopause clinic. A total of 83 of 99 PDs agreed or strongly agreed that their programs needed more menopause educational resources, and most (89.7%) stated they were likely or very likely to use self-paced menopause modules that include performance feedback if available. CONCLUSIONS: Data from the needs assessment questionnaire revealed that menopause education and resources vary across residency programs, with the majority lacking a dedicated menopause curriculum. Most PDs expressed a desire for more educational resources and standardized training materials, and preferred to access an online national menopause curriculum.

RESUMEN

This study examines how gender interacts with polyvictimization patterns in survivors' health problems using 8,587 survivors of intimate partner violence from the National Intimate Partner and Sexual Violence Survey, a nationally representative sample collected in 2010. Polyvictimization included six categories that were created in our previous work: sexual violence, physical and psychological violence, coercive control, multiple violence, stalking, and psychological aggression. Multiple violence was associated with chronic pain, headache, difficulty sleeping, and poor health perception. Females experiencing coercive control were more likely to have chronic pain than males. The appropriate assessment of gendered patterns of polyvictimization, and relevant subsequent services and support will better address health problems among survivors.

RESUMEN

Background: It is well known that there are gender differences in the health behaviour and physical and mental health of children. The COVID-19 pandemic influenced the health and lifestyles of children and adolescents by changing their living conditions. The present work investigates whether gender differences in selected health indicators are evident more than two years after the onset of the pandemic. Methods: In the study Kindergesundheit in Deutschland aktuell (KIDA) (German Children's Health Update), cross-sectional telephone surveys were conducted with parents of 3- to 15-year-olds (n=3,478). Parental information on the general and mental health of the child, on increased need for health care and mental health services, as well as on physical activity and utilisation of sports activities were queried in standardised manner. Gender differences were assessed using Chi2 tests. Results: A total of 91% of the girls and 92% of the boys had their general health assessed as being (very) good by their parents (difference not significant, n.s.). An increased need for care and support was indicated for 10.6% of the 3- to 15-year-olds (girls: 9%, boys: 12%, n.s.). Boys met the physical activity recommendations of the WHO significantly more often (60%) than girls (54%). Good to excellent mental health was reported for 93% of both boys and girls. When changes during the pandemic were reported, no differences were found in the responses for girls compared to boys. Conclusions: Gender differences were found for individual parameters and age groups. These differences must be assessed in the context of other social determinants of health, and need to be considered when planning preventive measures.

RESUMEN

Adverse childhood experiences (ACEs), including child maltreatment and other adversities in the home context and beyond (e.g., witnessing domestic violence; parental mental illness; parental separation; living in a disadvantaged neighborhood) are prevalent in the population and often covary together. Research based on the construct of ACEs has transformed the field of adult mental health, yet child and adolescent mental health has often been overlooked in this work. This special issue of Research on Child and Adolescent Psychopathology focuses on the developmental science of ACEs and child psychopathology. The research presented here draws on the extensive evidence base that now exists regarding the co-occurrence of common childhood adversities, while informing the integration of theory and research on ACEs with that of developmental psychopathology at large. This Introduction provides an overview of ACEs and child mental health from a developmental psychopathology perspective, with an emphasis on key concepts and recent progress spanning the prenatal period through to adolescence and intergenerational pathways. Models of ACEs that emphasize the multi-dimensional nature of adversity and the importance of developmental timing to risk and protective pathways, have played a driving role in this progress. Methodological innovations in this work are highlighted, along with implications for prevention and intervention.
