RESUMO
OBJECTIVE: To examine sex differences in social inferencing deficits after traumatic brain injury (TBI) and to examine the odds of men and women being impaired while controlling for potential confounders. DESIGN: Cross-sectional survey. SETTING: Two TBI rehabilitation hospitals. PARTICIPANTS: One hundred five participants with TBI (60 men, 45 women) and 105 controls without TBI (57 men, 48 women) (N=210). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Awareness of Social Inference Test (TASIT), which includes (1) Emotion Evaluation Test (EET), (2) Social Inference-Minimal (SI-M) test, and (3) Social Inference-Enriched (SI-E) test. RESULTS: Within the control sample, men and women performed similarly on all 3 TASIT subtests. Within the group with TBI, men had significantly lower scores than women on EET (P=.03), SI-M (P=.01), and SI-E (P=.04). Using impairment cutoffs derived from the sample without TBI, we found significantly more men with TBI (30%) were impaired on the EET than women (16.7%); impairment was similar between men and women on SI-M and SI-E. When adjusting for executive functioning and education, the odds of being impaired on the EET did not significantly differ for men and women (odds ratio, 0.47; 95% CI, 0.16-1.40; P=.18). CONCLUSIONS: Although more men with TBI have emotion perception deficits than women, the difference appears to be driven by education and executive functioning. Research is needed in larger samples with more definitive norms to better understand social inferencing impairments in men and women with TBI as well as translation to interpersonal behaviors.

OBJECTIVE: In participants with traumatic brain injury (TBI) and peer controls, examine (1) differences in negative attributions (interpret ambiguous behaviors negatively); (2) cognitive and emotional factors associated with negative attributions; and (3) negative attribution associations with anger responses, life satisfaction, and participation. SETTING: Two TBI outpatient rehabilitation centers. PARTICIPANTS: Participants with complicated mild to severe TBI (n = 105) and peer controls (n = 105). DESIGN: Cross-sectional survey study. MAIN MEASURES: Hypothetical scenarios describing ambiguous behaviors were used to assess situational anger and attributions of intent, hostility, and blame. Executive functioning, perspective taking, emotion perception and social inference, alexithymia, aggression, anxiety, depression, participation, and life satisfaction were also assessed. RESULTS: Compared with peer controls, participants with TBI rated behaviors significantly more intentional, hostile, and blameworthy. Regression models explained a significant amount of attribution variance (25%-43%). Aggression was a significant predictor in all models; social inference was also a significant predictor of intent and hostility attributions. Negative attributions were associated with anger responses and lower life satisfaction. CONCLUSION: People with TBI who have higher trait aggression and poor social inferencing skills may be prone to negative interpretations of people's ambiguous actions. Negative attributions and social inferencing skills should be considered when treating anger problems after TBI.

OBJECTIVES: To compare construct and predictive validity, readability, and time-to-administer of 2 negative attribution measures in participants with traumatic brain injury (TBI). SETTING: Two TBI rehabilitation hospitals. PARTICIPANTS: Eighty-five adults with complicated mild to severe TBI. MAIN MEASURES: Negative attributions (intent, hostility, and blame) and anger responses to hypothetical scenarios were measured with the Epps scenarios and the Ambiguous Intention Hostility Questionnaire (AIHQ). Trait aggression was measured with the Buss-Perry Aggression Questionnaire (BPAQ). RESULTS: Associations between attributions and anger responses (ie, construct validity) within each measure were significant (Epps: r = 0.61-0.74; AIHQ: r = 0.39-0.71); however, associations were stronger for Epps (Ps < .001). Receiver operating characteristics (ROC) revealed attributions from both measures predicted BPAQ scores (area under the ROC curves = 0.6-0.8); predictive validity did not statistically differ between the 2 measures. Both had comparable readability (fifth- to sixth-grade levels), but Epps required longer administration times. CONCLUSION: Negative attributions affect anger and aggression after TBI, making it important to identify suitable assessments for the TBI population. While psychometric properties of the AIHQ and Epps scenarios should be further explored, this study offers early support for the use of either instrument in persons with TBI. Advantages and disadvantages of the AIHQ and Epps scenarios are highlighted.

BACKGROUND: Values clarification can assist families facing the threat of periviable delivery in navigating the complexity of competing values related to death, disability, and quality of life (QOL). OBJECTIVE: We piloted values clarification exercises to inform resuscitation decision making and qualitatively assess perceptions of QOL. METHODS: We conducted a mixed-method study of women with threatened periviable delivery (22 0/7-24 6/7 weeks) and their important others (IOs). Participants engaged in three values clarification activities as part of a semi-structured interview-(a) Card sorting nine conditions as an acceptable/unacceptable QOL for a child; (b) Rating/ranking seven common concerns in periviable decision making (scale 0-10, not at all to extremely important); and (c) "Agreed/disagreed" with six statements regarding end-of-life treatment, disability, and QOL. Participants were also asked to define "QOL" and describe their perceptions of a good and poor QOL for their child. Analysis was conducted using SAS version 9.4 and NVivo 12. RESULTS: All mild disabilities were an acceptable QOL, while two-thirds of participants considered long-term mechanical ventilation unacceptable. Although pregnant women rated "Impact on Your Physical/Mental Health" (average 5.6) and IOs rated "Financial Concerns" the highest (average 6.6), both groups ranked "Financial Concerns" as the most important concern (median 5.0 and 6.0, respectively). Most participants agreed that "Any amount of life is better than no life at all" (pregnant women 62.1%; IOs 75.0%) and disagreed that resuscitation would cause "Too much suffering" for their child (pregnant women 71.4%; IOs 80.0%). Half were familiar with the phrase "QOL". Although the majority described a good QOL in terms of emotional well-being (eg "loved", "happy", "supported"), a poor QOL was described in terms of functionality (eg "dependent" and "confined"). Additionally, financial stability emerged as a distinctive theme when IOs discussed poor QOL. CONCLUSION: The study offers important insights on parental perspectives in periviable decision making and potential values clarification tools for decision support.

OBJECTIVES: (1) To explore the construct validity of the Ambiguous Intentions Hostility Questionnaire (AIHQ) in participants with traumatic brain injury (TBI) (ie, confirm negative attributions are associated with anger and aggression); and (2) use the AIHQ to examine negative attribution differences between participants with and without TBI. SETTING: Two rehabilitation hospitals. PARTICIPANTS: Eighty-five adults with TBI and 86 healthy controls (HCs). DESIGN: Cross-sectional survey. MAIN MEASURES: The AIHQ, a measure of negative attributions (intent, hostility, and blame), anger, and aggressive responses to hypothetical scenarios. RESULTS: Attributions were significantly correlated with anticipated anger and aggressive responses to AIHQ scenarios. Compared with HCs, participants with TBI reported stronger negative attributions (P ≤ .001), anger (P = .021), and aggressive responses (P = .002) to the scenarios. CONCLUSION: Negative attributions were associated with anger and aggression responses, demonstrating construct validity of the AIHQ in the TBI population. Participants with TBI judged others' behaviors more severely than HCs, similar to prior research using a different attribution measure. The AIHQ has promise as a practical instrument for assessing negative attributions after TBI.

OBJECTIVE: Breastfeeding has multiple benefits for women and babies. Understanding factors contributing to intention to exclusively breastfeed may allow for improving the rates in first-time mothers. The study objective was to examine factors associated with a woman's intention to breastfeed her first child. METHODS: A secondary analysis of the prospective "Nulliparous Pregnancy Outcomes Study: monitoring mothers-to-be" (nuMoM2b) study of nulliparous women in the U.S. with singleton pregnancies was performed. Sociodemographic and psychosocial factors were analyzed for associations with breastfeeding intention. RESULTS: For the 6443 women with complete information about breastfeeding intention and all factors under consideration, women who intended to breastfeed (either exclusively or any breastfeeding) were more likely to be older, not black, have reached a higher level of education, have higher incomes, have a lower body mass index (BMI), and be nonsmokers. Reporting a planned pregnancy and several psychosocial measures were also associated with intention to breastfeed. In the multivariable analysis for exclusive breastfeeding, in addition to age, BMI, race, income, education, and smoking, of the psychosocial measures assessed, only women with higher hassle intensity ratios on the Pregnancy Experience Scale had lower odds of exclusive breastfeeding intention (OR 0.71, 95% CI 0.55-0.92). Other psychosocial measures were not associated with either exclusive breastfeeding or any breastfeeding after controlling for demographic characteristics. CONCLUSIONS FOR PRACTICE: Several sociodemographic factors, having a planned pregnancy, and fewer intense pregnancy hassles compared to uplifts are associated with intention to exclusively breastfeed. Identifying these factors may allow providers to identify women for focused, multilevel efforts to enhance breastfeeding rates.

Symptoms of emotional distress during and after pregnancy may be introduced or exacerbated by unexpected medical conditions in the mother or fetus. Twin-twin transfusion syndrome (TTTS), which accounts for 17% of fetal deaths in twins and entails substantial medical uncertainty, may represent a particularly challenging pregnancy experience. Yet, little is known about the impact of TTTS on women's emotional health. We retrospectively surveyed 350 women who experienced a TTTS pregnancy about their experiences at three time points (prior to, during, and after pregnancy) to examine symptoms of anxiety and depression, mental health diagnoses, thoughts of seeking mental healthcare, help received, and preferred mental health services. Women in this study experienced significantly elevated symptoms of depression and anxiety during and after pregnancy, regardless of their pregnancy outcome (double survivor, single survivor, or double loss). Women reported feeling devastated by their experience and indicated they would have accepted mental healthcare had it been offered and had barriers to care been addressed. Prospective studies of women experiencing TTTS pregnancies are needed to examine TTTS effects on maternal mental health and to determine how to best address emotional care needs.

BACKGROUND: Fetal growth restriction can result from a variety of maternal, fetal, and placental conditions. Umbilical artery Doppler assesses the impedance to blood flow along the fetal component of the placental unit. An abnormal umbilical artery waveform reflects the presence of placental insufficiency and can help differentiate a growth-restricted fetus from the constitutionally small, thus guiding further management. The presence of persistently absent end-diastolic flow and reversed end-diastolic flow is an indication for inpatient antenatal surveillance and preterm delivery. There is no consensus on the optimal management of intermittent absent end-diastolic flow owing to a lack of data to support the ideal delivery timing for growth-restricted fetuses with this finding. OBJECTIVE: This study aimed to estimate the risks of adverse perinatal outcomes among growth-restricted pregnancies with persistently elevated, intermittently absent, and persistently absent end-diastolic flow. Fetal growth restriction is a common condition that is associated with an increased risk of fetal morbidity and mortality. Intermittently absent umbilical artery end-diastolic flow may be identified among pregnancies with fetal growth restriction. The fetal risks associated with persistently absent end-diastolic flow have been described. However, the risks associated with intermittent absent end-diastolic flow are not as well-known. STUDY DESIGN: We performed a retrospective cohort study including nonanomalous, singleton, growth-restricted pregnancies that received umbilical artery Doppler assessment at our institution from 2009 to 2020. Fetuses were classified into the following 3 categories: elevated umbilical artery Doppler, intermittent absent end-diastolic flow, and persistently absent end-diastolic flow. The Doppler categories were classified by the most severe in the pregnancy. The primary outcome was a composite of neonatal morbidity. RESULTS: Total 233 fetuses met the criteria. Of which 78 (33.0%) had elevated umbilical artery Doppler waveforms, 37 (16.0%) had intermittent absent end-diastolic flow, and 119 (51.0%) had absent end-diastolic flow. The composite outcome was statistically different between the groups, occurring in 16.9% with elevated umbilical artery Doppler waveforms (13/77), 35.1% (12/39) with intermittent absent end-diastolic flow, and 56.3% (65/127) with absent end-diastolic flow (P<.001). The odds ratio for the composite outcome was significantly increased in absent end-diastolic flow (odds ratio, 6.15; 95% confidence interval, 3.14-12.80) and was not significantly increased for intermittently absent end-diastolic flow (odds ratio, 2.46; 95% confidence interval, 0.98-6.19) when compared with elevated umbilical artery Doppler waveforms. When adjusted for gestational age at delivery and antenatal steroids, no difference was seen in the primary outcome for intermittent absent end-diastolic flow (adjusted odds ratio, 0.73; 95% confidence interval, 0.20-2.68) and absent end-diastolic flow (adjusted odds ratio, 1.44; 95% confidence interval, 0.51-4.07). CONCLUSION: Among growth-restricted pregnancies, intermittent absent end-diastolic flow is associated with a similar rate of composite neonatal morbidity as persistently elevated Doppler waveforms. In addition, there is no difference in composite neonatal morbidity between the 3 groups when corrected for gestational age at delivery and antenatal steroid administration. These similar outcomes should be considered when creating an antenatal surveillance plan and discussing the potential for outpatient management.

In the field of orthodontics, providing patients with accurate treatment time estimates is of utmost importance. As orthodontic practices continue to evolve and embrace new advancements, incorporating machine learning (ML) methods becomes increasingly valuable in improving orthodontic diagnosis and treatment planning. This study aimed to develop a novel ML model capable of predicting the orthodontic treatment duration based on essential pre-treatment variables. Patients who completed comprehensive orthodontic treatment at the Indiana University School of Dentistry were included in this retrospective study. Fifty-seven pre-treatment variables were collected and used to train and test nine different ML models. The performance of each model was assessed using descriptive statistics, intraclass correlation coefficients, and one-way analysis of variance tests. Random Forest, Lasso, and Elastic Net were found to be the most accurate, with a mean absolute error of 7.27 months in predicting treatment duration. Extraction decision, COVID, intermaxillary relationship, lower incisor position, and additional appliances were identified as important predictors of treatment duration. Overall, this study demonstrates the potential of ML in predicting orthodontic treatment duration using pre-treatment variables.
RESUMO
BACKGROUND AND AIMS: Diabetic retinopathy (DR) is the most common complication of diabetes. The inflammatory milieu of diabetes results in changes throughout the body. This study asked whether epigenetic changes in peripheral blood mononuclear cells (PBMCs) reflect DR severity. METHODS: PBMCs were separated from the whole blood of DR individuals using density gradient centrifugation. DNA was isolated, and methylation of micro-RNA (miR)-17-92 cluster was evaluated. RESULTS: We observed that the miR-17-92 cluster was hypermethylated in DR individuals; specifically, this change was most remarkable with proliferative-DR (PDR). CONCLUSIONS: miR-17-92 methylation in PBMCs could help understand DR's pathogenesis and identify individuals at the risk of severe DR for early intervention.

Objectives: The main objective of this study was to report stress and anxiety levels during the COVID-19 pandemic on early- to mid-career women researchers in healthcare sciences research and determine the associated factors. Methods: A 50-item self-administered internet questionnaire was developed using a mix of Likert-type scales and open-ended response questions. The survey was distributed June 10-August 3, 2020. Anxiety and stress as well as personal/family demands were assessed through validated measures (Patient Reported Outcomes Measurement Information System [PROMIS]-Anxiety Short Form and Perceived Stress Scale [PSS]) and open-ended responses. Results: One hundred and fifty-one early-career women in healthcare sciences research completed the survey; mean respondent age was 37.3 ± 5.2 years; and all had a college degree or higher, 50.3% holding a PhD and 35.8% MD. Race and ethnicity were reported in 128; the majority were White (74.0%). One-third (31.2%) reported being "very much" concerned about reaching their research productivity goals and 30.1% were "very much" concerned about academic promotion and tenure. Fifty percent reported a "moderate" PROMIS anxiety score and 72.1% reported a "moderate" PSS score. For the open-ended responses, 65.6% reported a worry about their professional goals because of the COVID-19 pandemic. Major concerns revolved around finances, childcare, and job security. Conclusions: Throughout the pandemic, early- and mid-career women in healthcare sciences research have reported moderate to high overall stress, anxiety, and worries. These concerns appear related to household settings, additional responsibilities, financial concerns, and reduced research productivity. Institutions and funding agencies should take these concerns into consideration and offer support.
RESUMO
AIM: To determine if the time to cervical change and time to active labor were different when misoprostol was administered by a vaginal or buccal route for cervical ripening in nulliparas undergoing labor induction at term. METHODS: This was a secondary analysis of nulliparous participants in the IMPROVE Study-A comparison of vaginal versus buccal misoprostol for cervical ripening for labor induction at term: a triple-masked randomized controlled trial (NCT02408315). The parent study was a non-inferiority randomized controlled trial in which patients beginning induction with a modified Bishop score ≤6 received either vaginal or buccal misoprostol and simultaneous placebo via the opposite route. The primary outcome of the parent study was time to delivery. Primary outcomes for this secondary analysis were the time to active labor (at least 6 cm dilated) and time to change in cervical dilation. Kaplan-Meier analysis was used to compare routes for time to active labor and multistate Markov modeling was used to compare sojourn times at each cervical dilation. RESULTS: Of the 300 participants enrolled in the parent trial, 124 (41.3%) were nulliparous; 59 (47.6%) nulliparous participants underwent induction with vaginal misoprostol and 65 (52.4%) received buccal dosing. Nulliparas receiving vaginal dosing required fewer doses of misoprostol to reach active labor (median 2 vs 3, p = .003). However, this did not result in shorter time to active labor (median vaginal 23.1 h, 95% CI = [21.6, 27.2 h]; buccal 25.6 h [21.5, 29.3 h], p = .45) or higher rate of vaginal delivery within 24 h; (33.9% vs 35.4%, p = .86). There was also no significant difference in time to active labor after adjusting for covariates (adjusted HR for dose route (buccal vs vaginal) = 0.91 [0.61, 1.36], p = .649). Among people that delivered vaginally, the mean sojourn times, measuring cervical dilation state change, were not significantly different, with mean duration to active labor of 20.5 [17.6, 24.5] h for buccal and 21.8 [17.7, 28.2] h for vaginal dosing (p = .092). Satisfaction and preference for dosing routes were not different between groups. CONCLUSION: Buccal and vaginal dosing of misoprostol for cervical ripening in nulliparas appear to have similar times to active labor and progression of cervical change during ripening.

BACKGROUND: Despite medical advances in the care of extremely preterm neonates and growing acceptance of resuscitation at 23 and even 22 weeks gestation, controversy remains concerning the use of antepartum obstetric intervention s that are intended to improve outcomes in the setting of anticipated extremely preterm birth. In the absence of demonstrated benefit at <23 weeks gestation and with uncertain benefit at 23 weeks gestation, previous obstetric committee opinions have advised against their use at these gestational ages. OBJECTIVE: The purpose of this study was to review the use of obstetric intervention s at the threshold of viability based on neonatal resuscitation plan and to review the odds of survival to neonatal intensive care unit discharge based on use of obstetric intervention s with adjustment for neonatal factors. STUDY DESIGN: This retrospective study of 6 study centers reviewed pregnant patients who were admitted between 22+0/7 and 24+6/7 weeks gestation facing delivery from 2011-2015. Patients with known anomalies or missing data were excluded. Records were reviewed for demographics, resuscitation plan, and obstetric intervention s. Mode of delivery, delivery room care, and final infant dispositions were recorded. Multiple gestations were included as 1 pregnancy in regard to the use of obstetric intervention s and were excluded from survival analysis. RESULTS: Four hundred seventy-eight mothers met the inclusion criteria. When resuscitation was planned, mothers were more likely to receive all conventional obstetric intervention s (antenatal steroids, magnesium sulfate for neuroprotection, tocolytics, and Group Beta Streptococcus prophylaxis), regardless of gestational age at admission, and were more likely to be delivered by cesarean section (P<.05). Analyzed as a group, when antenatal steroids, magnesium sulfate, tocolytics and Group Beta Streptococcus prophylaxis were administered, the odds of survival to neonatal intensive care unit discharge increased for newborn infants who were born at 22 (odds ratio, 11.33; 95% confidence interval, 1.405-91.4) and 23 weeks gestation (odds ratio, 15.5; 95% confidence interval, 3.747-64.11; P<.05). In singletons, the odds of survival to neonatal intensive care unit discharge was not improved by cesarean delivery vs vaginal delivery, even after adjustment for the use of additional interventions, weight, gender, and gestational age (odds ratio, 1.0; 95% confidence interval, 0.59-1.8; P=.912). CONCLUSION: In this study, when postnatal resuscitation was planned at 22 and 23 weeks gestation, women were more likely to receive antenatal steroids, magnesium sulfate, and antibiotics; provision of this bundle imparted survival benefit at 23 weeks gestation but could not be demonstrated at 22 weeks gestation because of the small sample size. These findings support of neonate-oriented obstetric interventions in the setting of delivery at 23 weeks gestation when resuscitation is planned and further exploration of optimal obstetric care when resuscitation of infants who were born at 22 weeks gestation is anticipated.

PURPOSE: To assess the relationship between decision quality and mental health outcomes for women and their important others (IO) 3 months following periviable birth. METHOD: Mental health outcomes were assessed prior to delivery and at 3 months postpartum using depression (PHQ-9), anxiety (GAD-7), and post-traumatic stress disorder (PTSD) (IES-22) scales. Decision quality was measured in terms of Decisional Conflict, Control, Regret, and Satisfaction with Decision. Descriptive analyses and linear regression modeling were conducted using SAS version 9.4. RESULT: We recruited 30 eligible women and 16 IOs. Participants had mild anxiety and depression, and symptoms of PTSD were among bereaved parents. Participants with lower decision control had higher levels of depression (women: p = 0.014; IOs: p = 0.059) and anxiety (women: p = 0.053; IOs: p = 0.032). Depression was also associated with higher decisional regret (women: p = 0.073; IOs: p = 0.023). CONCLUSION: Our findings suggest that decision quality is associated with mental health outcomes for families who experience periviable delivery.

BACKGROUND: The exposure of young adults to electronic cigarette (e-cigarette) advertisements has risen rapidly. E-cigarette ads have been shown to increase short term perceived acceptability of using e-cigarettes in places where traditional cigarettes are banned. We set out to investigate if advertising exposure was related to perceptions of harm, addictiveness, and acceptability of use of e-cigarettes in places where traditional cigarettes are banned. METHODS: Using a cross-sectional design, 6037 students at a large Midwestern university between the ages of 18-24 were surveyed about e-cigarette use and smoking status. Bivariate analyses were performed associating perception of harm, addictiveness, and acceptability of e-cigarette use in places where smoking is banned with demographic and other background factors, and e-cigarette advertising exposure through different media channels. Logistic regression analyses were used to explore the relationship of these factors on perceptions of harm, addictiveness and acceptability of e-cigarette use in places where smoking is banned. RESULTS: More than a quarter (27.4%) of respondents had used an e-cigarette, greater than half (53.2%) had seen an advertisement on TV and 42.0% had seen an advertisement on the Internet. Logistic regressions revealed that being white, male, an e-cigarette user, a smoker, having a mother who smoked, and Internet advertisement exposure were associated with lower perceived harm of e-cigarettes. The same factors, plus having seen advertisements on TV, were associated with increased likelihood of perceiving e-cigarette use in bars, stores, at work and in a dorm as acceptable. Perceiving use of e-cigarettes as acceptable in classrooms was also associated with the aforementioned factors and also included race. Only being male and an e-cigarette user were associated with lower perceived addictiveness of e-cigarettes. CONCLUSIONS: E-cigarette use is increasing in adolescents and young adults, as is exposure to e-cigarette advertising. Independent of nicotine use and demographics factors, e-cigarette advertising is associated with increased beliefs in acceptability of e-cigarette use in places where cigarettes are banned. E-cigarette advertisements may be responsible for normalizing e-cigarette use. Exposure to internet e-cigarette advertisements was associated with lower perceived harm; this may be due to the false health claims often made in internet advertisements.
