RESUMEN

OBJECTIVE: The purpose of the study was to investigate the association between discrimination by multiple sources (ie, teachers, students, and other adults) and early adolescents' behavioral problems (ie, internalizing, externalizing, and attention problems), also considering the protective role of parental warmth in the association. METHOD: Cross-sectional analyses were conducted with 3,245 early adolescents of color obtained from the Adolescent Brain Cognitive Development Study (ABCD Study) at year 1 follow-up (Y1), a large and diverse sample of children (mean age = 9.48 years) in the United States. Racially-ethnically minoritized adolescents reported sources of discrimination, parental warmth, and symptoms of psychopathology. Regression with interaction terms was conducted to investigate the associations among sources of discrimination, parental warmth, and behavioral problems among racially-ethnically minority adolescents. Sensitivity analyses were conducted to examine (1) race/ethnicity and sex/gender variations; (2) whether the associations between different sources of discrimination and behavioral problems were reliably different; and (3) effects of discrimination, parental warmth, and their interplay at Y1 in predicting adolescents' behavioral problems at year 2 follow-up. RESULTS: Early adolescents experiencing interpersonal racial-ethnic discrimination by multiple sources, including teachers, students, and other adults, reported higher levels of attention, internalizing, and externalizing problems. Parental warmth was protective for the association between interpersonal racial-ethnic discrimination and early adolescents' behavioral problems. CONCLUSION: Experiencing interpersonal racial-ethnic discrimination from teachers, peers, and other adults is related to heightened attention, internalizing, and externalizing problems among racially-ethnically minoritized early adolescents. Parental warmth may reduce the risk of developing behavioral problems among early adolescents who experience interpersonal racial-ethnic discrimination from students, teachers, and other adults outside of school.

RESUMEN

This study used a three-wave longitudinal dataset to: identify adjustment profiles of U.S. Mexican-origin adolescents based on their physical, academic, and psychosocial health adjustment; track adjustment profile changes throughout adolescence; and examine the associations between cultural stressors, family obligation, and adjustment profile membership over time. Participants were 604 Mexican-origin adolescents (54% female, Mage = 12.41, SD = 0.97) in Texas (Wave 1: 2012-2015; Wave 2: 2013-2016; Wave 3: 2017-2020). Three concurrent profiles (Well-adjusted, Moderate, and Poorly-adjusted) emerged at each wave, whereas three transition profiles (Improved, Stable well-adjusted, and Overall poorly-adjusted) were identified across three waves. The results suggest that cultural stressors pose risks for Mexican-origin adolescents' adjustment, and family obligation values play a protective role in these associations.

RESUMEN

A 64-year-old woman was admitted to the hospital for sudden weakness in one of her left limbs. The patient was diagnosed with acute ischemic stroke (IS) of undetermined cause and received intravenous thrombolysis. Following thrombolysis, the patient's left limb weakness improved, but she subsequently developed recurrent high fever and delirium. Further diagnostic tests revealed that she had been infected with Brucella melitensis. The patient showed significant improvement during anti-infection treatment for Brucellosis and secondary prevention treatment for IS. However, her condition unexpectedly worsened on the 44th day after admission due to a hemorrhagic stroke (HS), which required an urgent craniotomy. Immunohistochemical analysis of the hematoma sample collected during the operation showed the presence of CD4+ and CD8+ T lymphocytes surrounding the blood vessels. This case highlights the unique challenge of managing IS in brucellosis and sheds light on the potential role of T lymphocytes in the immune response related to stroke.

RESUMEN

Atherosclerosis (AS) is the underlying cause of many severe vascular diseases and is primarily characterized by abnormal lipid metabolism. Paeonol (Pae), a bioactive compound derived from Paeonia Suffruticosa Andr., is recognized for its significant role in reducing lipid accumulation. Our research objective is to explore the link between lipid buildup in foam cells originating from macrophages and the process of ferroptosis, and explore the effect and mechanism of Pae on inhibiting AS by regulating ferroptosis. In our animal model, ApoE-deficient mice, which were provided with a high-fat regimen to provoke atherosclerosis, were administered Pae. The treatment was benchmarked against simvastatin and ferrostatin-1. The results showed that Pae significantly reduced aortic ferroptosis and lipid accumulation in the mice. In vitro experiments further demonstrated that Pae could decrease lipid accumulation in foam cells induced by oxidized low-density lipoprotein (LDL) and challenged with the ferroptosis inducer erastin. Crucially, the protective effect of Pae against lipid accumulation was dependent on the SIRT1/NRF2/GPX4 pathway, as SIRT1 knockdown abolished this effect. Our findings suggest that Pae may offer a novel therapeutic approach for AS by inhibiting lipid accumulation through the suppression of ferroptosis, mediated by the SIRT1/NRF2/GPX4 pathway. Such knowledge has the potential to inform the creation of novel therapeutic strategies aimed at regulating ferroptosis within the context of atherosclerosis.

RESUMEN

PURPOSE: The study aimed to investigate longitudinal, bidirectional associations between discrimination due to multiple reasons (race/ethnicity, sexual orientation, weight; termed multiple discrimination) and substance use (SU) intention in late childhood. These associations were compared across youth with no, single, and multiple (i.e., intersecting) marginalized identities based on race/ethnicity, sexual orientation, and overweight status. METHODS: Data were drawn from a national sample of youth in the Adolescent Brain Cognitive Development study (N = 8,530; 9-12 years old). Youth reported both their experiences of multiple discrimination (the number of forms of discrimination youth experienced) and SU intention at one-year and two-year follow-ups. Theoretically relevant covariates were included. RESULTS: Compared to non-marginalized youth (n = 2,689) and youth with single marginalized identities (n = 3,399), youth with intersecting marginalized identities (n = 2,442) reported the highest SU intention and multiple discrimination across waves. Only for this last group, multiple discrimination predicted stronger SU intention subsequently (ß = 0.07, 95% confidence interval [0.02, 0.11]), whereas stronger SU intention predicted lower levels of multiple discrimination over time (ß = -0.06, 95% confidence interval [-0.09, -0.02]). Sensitivity analyses yielded similar patterns with some nuances among subgroups of youth with varying intersecting marginalized identities. DISCUSSION: Multiple discrimination predicted stronger SU intention over time in late childhood, particularly among youth with intersecting marginalized identities. Policies and practices should consider addressing multiple discrimination to reduce SU disparities among diverse youth.

RESUMEN

This study examines social-cultural contributors and developmental outcomes of language brokers. From 2012 to 2020, three waves of data were collected from 604 Mexican-origin adolescent language brokers (Mage = 12.92, SD = 0.92, 54% girls). The study (1) identified four distinct subgroups of language brokers (efficacious, conservative, nonchalant, and burdened) who translated for mothers and fathers, after incorporating objective bilingual proficiency along with multiple dimensions of language brokering; (2) showed that early adolescents' Mexican, rather than U.S., cultural values and orientation were related to later language brokering profiles; and (3) showed that the efficacious group was the most resilient while burdened was the most vulnerable to developmental problems. Preservation of Mexican culture may facilitate language brokering experiences related to more positive developmental outcomes.

RESUMEN

BACKGROUD: High comorbidity rates have been reported in patients with atherosclerosis and osteoporosis, posing a serious risk to the health and well-being of elderly patients. To improve and update clinical practice regarding the joint treatment of these two diseases, the common mechanisms of atherosclerosis and osteoporosis need to be clarified. MicroRNAs (miRNAs), are importance molecules in the pathogenesis of human diseases, including in cardiovascular and orthopedic fields. They have garnered interest as potential targets for novel therapeutic strategies. However, the key miRNAs involved in atherosclerosis and osteoporosis and their precise regulation mechanisms remain unknown. Paeonol (Pae), an active ingredient in Cortex Moutan, has shown promising results in improving both lipid and bone metabolic abnormalities. However, it is uncertain whether this agent can exert a cotherapeutic effect on atherosclerosis and osteoporosis. OBJECTIVE: This study aimed to screen important shared miRNAs in atherosclerotic and osteoporotic complications, and explore the mechanism of the protective effects of Pae against atherosclerosis and osteoporosis in high-fat diet (HFD)-fed ApoE-/- mice. METHODS: An experimental atherosclerosis and osteoporosis model was established in 40-week-old HFD ApoE-/- mice. Various techniques such as Oil Red O staining, HE staining and micro-CT were used to confirm the co-occurrence of these two diseases and efficacy of Pae in addition to the associated biochemical changes. Bioinformatics was used to screen key miRNAs in the atherosclerosis and osteoporosis model, and gene involvement was assessed through serum analyses, qRT-PCR, and western blot. To investigate the effect of Pae on the modulation of the miR let-7g/HMGA2/CEBPß pathway, Raw 264.7 cells were cocultured with bone marrow mesenchymal stem cells (BMSCs) and treated with an miR let-7g mimic/inhibitor. RESULTS: miR let-7g identified using bioinformatics was assessed to evaluate its participation in atherosclerosis-osteoporosis. Experimental analysis showed reduced miR let-7g levels in the atherosclerosis-osteoporosis mice model. Moreover, miR let-7g was required for BMSC - Raw 264.7 cell crosstalk, thereby promoting foam cell formation and adipocyte differentiation. Treatment with Pae significantly reduced plaque accumulation and foam cell number in the aorta while increasing bone density and improving trabecular bone microarchitecture in HFD ApoE-/- mice. Pae also increased the level of miR let-7g in the bloodstream of model mice. In vitro studies, Pae enhanced miR let-7g expression in BMSCs, thereby suppressing the HMGA2/CEBPß pathway to prevent the formation of foam cells and differentiation of adipocytes induced by oxidized low-density lipoprotein (ox-LDL). CONCLUSION: The study results suggested that miR let-7g participates in atherosclerosis -osteoporosis regulation and that Pae acts as a potential therapeutic agent for preventing atherosclerosis-osteoporosis through regulatory effects on the miR let-7g/HMGA2/CEBPß pathway to hinder foam cell formation and adipocyte differentiation.

RESUMEN

PURPOSE: This study sought to examine whether the daily associations between ethnic/racial discrimination and stress responses served as mediators linking ethnic/racial identity (ERI), adolescent sleep health, and somatic symptoms. METHODS: Data were drawn from 279 adolescents of color (69% female; 24% African Americans; 31% Asian Americans; 41% Latinx; and 4% unknown ethnicity/race; Mage = 14.31 years, SD = 0.65). Adolescents first completed an online survey about ERI exploration and commitment; and then 14-day diaries on ethnic/racial discrimination and stress responses (i.e., rumination and problem-solving coping), and finally, a post-diary survey about sleep and somatic health over the past two weeks. This study adopts slope-as-mediator mediation modeling, a novel approach highlighting the role of daily-level experiences in developmental processes by examining the day-to-day association between two variables as an explanatory mechanism. RESULTS: The daily associations between ethnic/racial discrimination and two stress responses significantly mediated the link between ERI exploration and adolescents' subsequent sleep and somatic health. For ERI commitment, only the mediating pathway of the association between ethnic/racial discrimination and problem-solving coping was significant. DISCUSSION: Daily responses to ethnic/racial discrimination, both adaptively and maladaptively, could in part explain the association between ERI exploration and adolescent health. Active participation in cultural activities may increase adaptive responses to ethnic/racial discrimination; meanwhile, uncertainty about ERI may lead to maladaptive reactions such as rumination. For ERI commitment, only problem-solving coping with ethnic/racial discrimination mediated the links to health outcomes, an observation possibly explained by the benefits of holding a strong sense of commitment to ERI.

RESUMEN

This study aimed to (1) identify differences in sleep patterns between Filipino migrants and non-migrants across 2 years and (2) explore the impact of discrimination trajectories on sleep trajectories. The Health of Philippine Emigrants Study (HoPES) consisted of a migrant (n = 832) and non-migrant cohort (n = 805), with baseline data collected in the Philippines. Both cohorts were followed longitudinally, with the non-migrants followed in the Philippines and the migrant cohort followed to the United States. Sleep duration, quality, and difficulty were assessed with the National Institutes of Health Patient-Reported Outcomes Information System (PROMIS) inventory, and discrimination was measured with an adapted version of the Everyday Discrimination scale. Migrants reported a faster decline in sleep duration (- 12 min a year) but higher sleep quality than non-migrants over 2 years. Migrants who reported high initial levels of everyday discrimination also reported faster declines in sleep duration and a slower decline in sleep difficulty. Further, migrants who reported stable (versus declining) levels of discrimination over 2 years reported a faster decline in sleep quality. These results speak to the complexity of immigrant health patterns and long-term associations between discrimination and sleep processes.

RESUMEN

INTRODUCTION: The aim of this study was to discuss the safety of rapid administration of 4°C hypothermic normal saline into the occluded vessels using an intra-arterial catheter to induce mild hypothermia following endovascular thrombectomy in patients with acute large vessel occlusion cerebral infarction. METHODS: We selected 78 patients with acute large vessel occlusion cerebral infarction who underwent endovascular thrombectomy in the Department of Neurology of our hospital from January 2020 to July 2022 and achieved TICI 2b recanalization. RESULT: Twenty-five patients were administered 500 mL of 4°C hypothermic normal saline in the occluded vessels at a rate of 25 mL/min to induce mild hypothermia. Twenty pairs of subjects conformed to strict matching and were finally included in the statistical analysis. The two groups of patients differed significantly in white blood cell count and percentage of neutrophils (p < 0.05); however, there were no significant differences in D-dimer, procalcitonin, and BNP levels. The two groups of patients did not differ significantly with respect to the incidence of the following indicators: upper gastrointestinal bleeding; pulmonary infection; venous thrombosis; vasospasms; seizures; and chills (p > 0.05). CONCLUSION: Mild therapeutic hypothermia in target vessels plus endovascular thrombectomy was shown to be safe in patients with acute large vessel occlusion cerebral infarction.

RESUMEN

Mechanical allodynia and hyperalgesia are intractable symptoms lacking effective clinical treatments in patients with neuropathic pain. However, whether and how mechanically responsive non-peptidergic nociceptors are involved remains elusive. Here, we showed that von Frey-evoked static allodynia and aversion, along with mechanical hyperalgesia after spared nerve injury (SNI) were reduced by ablation of MrgprdCreERT2-marked neurons. Electrophysiological recordings revealed that SNI-opened Aß-fiber inputs to laminae I-IIo and vIIi, as well as C-fiber inputs to vIIi, were all attenuated in Mrgprd-ablated mice. In addition, priming chemogenetic or optogenetic activation of Mrgprd+ neurons drove mechanical allodynia and aversion to low-threshold mechanical stimuli, along with mechanical hyperalgesia. Mechanistically, gated Aß and C inputs to vIIi were opened, potentially via central sensitization by dampening potassium currents. Altogether, we uncovered the involvement of Mrgprd+ nociceptors in nerve injury-induced mechanical pain and dissected the underlying spinal mechanisms, thus providing insights into potential therapeutic targets for pain management.

RESUMEN

OBJECTIVES: Cognitive control predicts functional independence and cognitive health outcomes, but is yet to be known the extent to which social stress, like discrimination, may diminish cognitive control capacities in Mexican-origin women. We evaluated the prospective associations between everyday and ethnic discrimination on cognitive control and examined the mediating effects of depressive symptoms on these links. We further examined the extent to which associations varied by age and financial strain. METHODS: We used data from 596 Mexican-origin women (average age = 38.89, standard deviation = 5.74) who participated in a 3-wave longitudinal study spanning 8 years (from 2012 to 2020). Participants completed measures of everyday and ethnic discrimination at Wave 1, depressive symptoms in Waves 1 and 2, and completed computer-based tasks of cognitive control at Wave 3. Self-reported assessments of financial strain were completed at Wave 2. Moderated mediation structural equation models were implemented to test hypotheses. RESULTS: Depressive symptoms significantly mediated the prospective association between everyday/ethnic discrimination to cognitive control. Higher levels of everyday and ethnic discrimination at baseline were associated with more depressive symptoms at Wave 2, which were then related to poorer cognitive control (i.e., longer reaction time in congruent and/or incongruent trials) at Wave 3. There was no significant moderation of age. Among those with low financial strain, higher levels of everyday discrimination were related to faster response times. DISCUSSION: Results revealed the long-term consequences of experiences with discrimination on cognitive control that operate through increased depressive symptoms and that may have some subtle differential effects across levels of financial strain.

RESUMEN

BACKGROUND: Paeonol (Pae), the main active compound of the root of Paeonia albiflora, is efficacious in treating atherosclerosis (AS). Endothelial dysfunction is throughout the pathological progression of AS. It is expected that inhibition of Endothelial-to-mesenchymal transition (EndMT) will be a key target for AS treatment. OBJECTIVE: In this study, we investigated the molecular mechanism of the regulatory effect of Pae on EndMT in human umbilical vein endothelial cells (HUVECs). METHODS: Cell cytotoxicity, proliferation, and migration were detected by CCK-8, the wound healing assay, and EdU staining, respectively. The protein expressions were measured by Western blot or immunofluorescence staining. Immunofluorescence staining was performed to indicate endothelial cells undergoing EndMT in ApoE-/- mice. In vitro TGF-ß1-induced EndMT assays were performed in HUVECs and the effect of Pae was explored. RESULTS: We demonstrated that Pae could improve induced TGF-ß1-EndMT in vivo and in vitro. Mechanism study revealed that Pae directly bonds to the activin-like kinase 5 (ALK5, also known as TGFß type I receptor), inhibited downstream Smad2/3 phosphorylation, and thus alleviated EndMT. Notably, overexpression of ALK5 significantly reversed the inhibitory effect of Pae on EndMT in HUVECs. CONCLUSION: Our results indicate that ALK5 is a promising druggable target for AS, and pharmacological regulation of ALK5-Smad2/3 signaling pathway with small-molecule holds great potential to benefit AS patients.

RESUMEN

Previous studies have linked parent-child cultural adaptation mismatches with adolescents' maladjustment without addressing how intergenerational mis/matches are related to positive aspects of adolescent development and parental outcomes. Using data from 604 Mexican-origin families (adolescent sample:54%female, Mage = 12.41, range = 11 to 15), response surface analysis was conducted to investigate how mother-child mis/matches in cultural adaptation (acculturation, enculturation, English and Spanish proficiency) are associated with adolescents' and mothers' resilience and life meaning. Adolescents and mothers reported greater resilience and meaning when they matched at higher, versus lower, levels of acculturation, enculturation and English proficiency; adolescents reported more resilience when they were more acculturated than mothers. The findings provide a strengths-based understanding of parent-child cultural adaptation mis/matches and elucidate how Mexican-origin families thrive in the cultural adaptation process.

RESUMEN

This study examined the associations of language brokering stress intensity and exposure with Mexican-origin youths' cortisol responses when brokering for fathers and mothers, and the moderating role of youths' brokering efficacy in these relations. Participants were 289 adolescents (Mage  = 17.38, SD = .94, 52% girls) in immigrant families. When brokering for mothers, stress exposure was related to flatter (less healthy) same-day diurnal slopes in youth. When brokering for fathers, daily brokering efficacy buffered the detrimental link between stress intensity and youths' same-day cortisol slopes. When brokering for fathers/mothers, stress intensity and exposure were related to flatter (less healthy) next-day diurnal slopes. Although daily brokering stress can relate to youth physiologic functioning, feeling efficacious about brokering may buffer the negative ramifications of stress.

RESUMEN

Although Mexican-origin youth with first-generation immigrant parents are relatively good at retaining their heritage language of Spanish, limited research has been conducted on their Spanish language development during adolescence. From three-wave longitudinal data across six years (Nwave1 = 604, Mage.wave1 = 12.91, 54% female), distinct groups of adolescents with consistently high, improved, declined, and consistently low Spanish proficiencies were identified. Family relationship quality was more predictive of adolescents' Spanish proficiency than family language environment. The benefits of Spanish proficiency were consistent across adolescents' ethnic identity, resilience, and life meaning. More research and practical attention to parent-adolescent relationships is needed to capitalize on the continued plasticity of adolescents' Spanish language development and to promote consequent positive outcomes.

RESUMEN

Using a three-wave longitudinal data set of Mexican-origin adolescents (N = 602, Mage = 12.92, SD = 0.91 at Wave 1), this study examines parallel pathways from early exposure to ethnic discrimination and drug-using peers, separately, to underage drinking status by late adolescence. Negative affect was expected to mediate the link from ethnic discrimination to underage drinking status (the stress-induced pathway), whereas social alcohol expectancy was expected to mediate the link from drug-using peers to underage drinking status (the socialization pathway). Our findings lend support to the stress-induced pathway while controlling for the socialization pathway. For the stress-induced pathway, we found that early ethnic discrimination experiences were related to higher likelihood of having engaged in underage drinking by late adolescence through elevated negative affect sustained across adolescence. For the socialization pathway, we found no association between affiliation with drug-using peers in early adolescence and underage drinking status, either directly or indirectly. Present findings highlight the unique role of early ethnic discrimination experiences in underage drinking among Mexican-origin adolescents, over and above the effect of drug-using peers. Alcohol use interventions targeting ethnic minority adolescents should account for adolescents' ethnic discrimination experiences by helping adolescents develop adaptive coping strategies to handle negative affect induced by discrimination (e.g., reappraisal) rather than using alcohol to self-medicate.

RESUMEN

Mexican-origin children from immigrant families are impacted by various systemic oppressions in life. The study seeks to examine how adolescents' developmental outcomes are associated with specific phenotypic, psychological, and social features of skin color, as manifested by skin tone, skin color satisfaction, and foreigner stress. By taking a holistic approach, we examine both positive and negative adjustment outcomes, including delinquency, resilience, and effortful control. Participants were 604 Mexican-origin adolescents aged between 11.08 and 15.29 (Mage = 12.91, SD = 0.92) with at least one immigrant parent. The findings highlight the harm of foreigner stress and the benefit of skin color satisfaction in Mexican-origin adolescents' development of delinquency, resilience, and effortful control, especially for those with a darker skin color.

RESUMEN

The current study investigates how and under what conditions family obligation benefits Mexican American adolescents' adjustment. The study used two waves of data from 604 Mexican American adolescents (54.3% female, Mage.wave1 = 12.41 years, SD = 0.97) and their parents. Structural equation modeling revealed that both adolescents' and parents' sense of family obligation related to more supportive parenting (i.e., parental monitoring, warmth, and inductive reasoning), which linked to better adolescent adjustment (i.e., sense of life meaning, resilience, and grades). There were parent gender differences: Adolescents' family obligation was more strongly related to their reports of maternal (vs. paternal) parenting. The links also varied across informants for parenting: (a) individuals' sense of family obligation related only to their own perceptions of parenting and (b) there were more evident associations between adolescent-reported (vs. parent-reported) parenting and adolescent outcomes.

RESUMEN

The intergenerational transmission of executive function may be enhanced or interrupted by culturally salient environmental stressors that shape the practice of executive function in the family. Building upon past research, the current study tests whether culturally relevant stressors such as economic stress and foreigner stress have a direct effect on adolescent executive function, as well as whether they modify the intergenerational transmission of mother-child executive function (i.e., working memory, inhibitory control, and shifting) in low-income Mexican immigrant families. The sample consists of 179 Mexican American adolescents (Mage = 17.03 years; SDage = 0.83; 58% females) and their Mexico-born mothers (Mage = 43.25 years; SDage = 5.90). Results show that mothers' perceived economic stress is associated with poor inhibitory control in adolescents. Low levels of mothers' perceived foreigner stress related to a stronger association between mothers' and adolescents' working memory, while high levels of mothers' perceived foreigner stress related to enhanced intergenerational transmission of poor shifting ability. Study findings demonstrate the prominence of perceived foreigner stress as a contextually relevant factor moderating the intergenerational transmission of mother-child executive function in low-income Mexican immigrant families.
