RESUMO

Adult acute myeloid leukemia (AML) patients under the age of 60 often receive similar intensive treatments, while outcomes between the adolescent and young adult (AYA) age group (18-39) and middle-aged adults (40-60 years) were seldom reported. We aim to study the characteristics and outcomes of AYA patients in comparison to middle-aged adults. A retrospective analysis was performed on AYA patients treated at Princess Margaret Cancer Center between 2008 and 2018. The primary outcomes include overall survival (OS), cumulative incidence of relapse (CIR), and non-relapse mortality (NRM). A total of 174 AYA patients and 176 middle-aged patients were included, with propensity score matching adjusting for potential major confounders. Comparing AYA and middle-aged patients, 5-year OS rates were similar at 54.6 % vs. 56.5 % (p=0.91), CIR rates at 29.5 % vs. 23.1 % (p=0.31), and similar NRM rates. Notably, non-transplanted AYA patients had a significantly higher CIR (39.8 %) compared to middle-aged patients (19.6 %) (p=0.0324), with more primary refractory/early relapsing disease. An observed trend toward improved OS in AYA patients post-2015 coincided with FLAG-IDA and haploidentical transplant implementations. In conclusion, the study suggests that AYA patients, particularly those not undergoing transplantation, may benefit from more intensive treatment strategies, emphasizing the need for tailored approaches in this age group.

RESUMO

Background: Suicide is a leading cause of death in adolescents and young adults globally. Well-established risk factors for suicide are depression and past suicide attempts. People experiencing suicidality may represent a distinct neurobiological group of people with depression. Because converging evidence has implicated inflammation in depression, we sought to investigate relationships between suicidality and immune markers in youth experiencing diverse mood and anxiety symptoms. We hypothesized that adolescents with suicidality would exhibit a unique immune signature. Methods: Adolescents underwent semi-structured interviews and completed self-reported measures to assess psychopathology, including suicidality (suicidal ideation, plans, or attempts). Fasting blood samples were collected, cultured with and without lipopolysaccharide (LPS) to stimulate an inflammatory response, and analyzed for 41 immune analytes. To assess how immune function related to suicidality categorically and dimensionally, we conducted group comparisons and correlations while controlling for multiple comparisons using false discovery rate (FDR). To further uncover subtle immune-suicidality relationships, we employed a data-driven approach using factor analysis to extract major immune factors, each of which was subsequently correlated with suicidality measures. Results: Among 126 participants, 29 were healthy controls and 97 participants had internalizing symptoms; within the clinical group, 57 experienced suicidality. Three immune analytes differed between healthy controls, suicidal, and non-suicidal adolescents with internalizing symptoms in the LPS condition: Flt-3L (p FDR = 0.0246), GM-CSF (p FDR = 0.0246), and IFN-γ (p FDR = 0.0246). These analytes were negatively correlated with the Beck Scale for Suicide Ideation (BSSI): Flt-3L (ρ = -0.19, p = 0.04); GM-CSF (ρ = -0.26, p = 0.004); IFN-γ (ρ =-0.33, p = 0.0003). GM-CSF also negatively correlated with number of suicide attempts (ρ = -0.39, p = 0.003). Factor analysis reduced 41 analytes to several common immune factors across experimental conditions, with Flt-3L, GM-CSF, and IFN-γ all loading heavily onto immune factors that were hypoactive in suicidality. Through this data-driven approach, we detected further associations between suicidality and immune factors across all conditions. Conclusions: Peripheral immune function may be distinctly altered in adolescent suicidality. Future work should examine immune-suicidality relationships longitudinally.

RESUMO

Introduction: Nutrition, sleep and physical activity are termed the "big three" health enhancing behaviors (HEB) associated with psychological distress and wellbeing. This study sought to understand differential associations between an expanded group of HEB (nutrition, sleep, physical activity, mindfulness, social connectedness) and psychological distress/wellbeing in early adolescents. Methods: Correlational and regression analyses were conducted in N=103 (51% females) adolescents (12.6 ± 0.3 years of age) recruited from the Longitudinal Adolescent Brain Study. Results: Higher scores on sleep, social connectedness and mindfulness scales were significantly associated with lower psychological distress scores. While higher scores on social connectedness and mindfulness scales were significantly associated with higher wellbeing scores. When adjusting for sex, nutrition, sleep, social connectedness and mindfulness accounted for a significant proportion of variance in the psychological distress model whereas physical activity and social connectedness accounted for a significant proportion of the variance in the wellbeing model. Discussions: Overall findings make a strong case for expansion of the "big three" HEB to include mindfulness and social connectedness, especially given social connectedness emerged as the strongest predictor of both psychological distress and wellbeing. In addition, this research suggests that early adolescent nutrition, sleep quality, and mindfulness should be prioritized in efforts to reduce risk of difficulties, and physical activity prioritized as a protective factor for wellbeing in this population. Findings have implications for interventions, emphasizing the importance of addressing HEB factors comprehensively and tailoring strategies to the unique needs of early adolescents to foster positive mental health outcomes.

RESUMO

Background: With the advent of electronic nicotine delivery systems, the use of nicotine and tobacco products (NTPs) among adolescents and young adults remains high in the US. Use of e-cigarettes additionally elevates the risk of problematic use of other substances like cannabis, which is often co-used with NTPs. However, their effects on brain health, particularly the hippocampus, and cognition during this neurodevelopmental period are poorly understood. Methods: Healthy late adolescents/young adults (N = 223) ages 16-22 completed a structural MRI to examine right and left hippocampal volumes. Memory was assessed with the NIH Toolbox Picture Sequence Memory Test (PSMT) and Rey Auditory Verbal Learning Test (RAVLT). Cumulative 6-month NTP and cannabis episodes were assessed and modeled continuously on hippocampal volumes. Participants were then grouped based on 6-month NTP use to examine relationships with the hippocampus and memory: current users (CU) endorsed weekly or greater use; light/abstinent users (LU) endorsed less than weekly; and never users (NU). Results: NTP use predicted larger hippocampal volumes bilaterally while cannabis use had no impact nor interacted with NTP use. For memory, larger left hippocampal volumes were positively associated with PSMT performance, RAVLT total learning, short delay and long delay recall for the NU group. In contrast, there was a negative relationship between hippocampal volumes and performances for LU and CU groups. No differences were detected between NTP-using groups. Conclusion: These results suggest that the hippocampus is sensitive to NTP exposure during late adolescence/young adulthood and may alter typical hippocampal morphometry in addition to brain-behavior relationships underlying learning and memory processes.

RESUMO

BACKGROUND:  The prevalence of smokeless tobacco, areca nut, and e-cigarette use among university students has raised concerns regarding their potential impact on oral health. Assessing students' knowledge, attitudes, and practices toward these substances is necessary. Understanding these factors can inform targeted interventions and policies promoting oral health among this population. This study aims to investigate the awareness levels, attitudes, and behaviors of university students regarding smokeless tobacco, areca nut, and e-cigarette use and their potential effects on oral health. Identifying gaps in knowledge and misconceptions will help guide educational initiatives and public health interventions tailored to the needs of university students. METHODOLOGY:  The study employed a designed questionnaire, comprising 20 closed-ended queries, administered via the Google Forms platform. This survey was disseminated among college students in Chennai to gather insights for the study. RESULTS: Of the 500 college students included in the study, almost 85.5% (427) were aware of the harmful effects of smokeless tobacco on oral health. Additionally, 74.6% (373) recognized that chewing areca nut contributes to poor oral health, while 59.8% (299) acknowledged the negative impact of e-cigarette use. CONCLUSIONS: The present study concluded that 11.1% (6) used smokeless tobacco, 18.9% (94) chewed areca nut, and 1.9% (10) used areca nut along with tobacco. Regarding e-cigarettes, 3.9% (19) indulged in vaping as a substitute for smoking regular cigarettes and 12.1% (61) used it along with tobacco cigarettes. It was also noted that 27.8% (139) were trying to quit and 12.6% (63) have tried but could not succeed. Therefore, although there was awareness of the ill effects of these deleterious habits on oral health and the increased risk of oral cancer, there remains a need to educate individuals and provide support for quitting these habits. Our study will provide insights into the present scenario of the awareness of the association between oral health and tobacco/areca nut consumption among college students in Chennai city.

RESUMO

Substance use, including cigarettes and cannabis, is associated with poorer sustained attention in late adolescence and early adulthood. Previous studies were predominantly cross-sectional or under-powered and could not indicate if impairment in sustained attention was a predictor of substance use or a marker of the inclination to engage in such behavior. This study explored the relationship between sustained attention and substance use across a longitudinal span from ages 14 to 23 in over 1000 participants. Behaviors and brain connectivity associated with diminished sustained attention at age 14 predicted subsequent increases in cannabis and cigarette smoking, establishing sustained attention as a robust biomarker for vulnerability to substance use. Individual differences in network strength relevant to sustained attention were preserved across developmental stages and sustained attention networks generalized to participants in an external dataset. In summary, brain networks of sustained attention are robust, consistent, and able to predict aspects of later substance use.

RESUMO

A prominent challenge in understanding neural consequences of substance use involves disentangling predispositional risk factors from resulting consequences of substance use. Existing literature has identified pre-existing brain variations as vulnerability markers for substance use throughout adolescence. As early initiation of use is an important predictor for later substance use problems, we examined whether pre-existing brain variations are associated with early initiation of use. In the Generation R Study, a prospective population-based cohort, brain morphology (gray matter volume, cortical thickness and surface area) was assessed at ages 10 and 14 using neuroimaging. In the second wave, participants reported on alcohol and tobacco use initiation. From a base study population (N = 3019), we examined the longitudinal (N = 2218) and cross-sectional (N = 1817) association between brain morphology of frontolimbic regions of interest known to be associated with substance use risk, and very early (age < 13) alcohol/tobacco use initiation. Additionally, longitudinal and cross-sectional associations were examined with a brain surface-based approach. Models were adjusted for age at neuroimaging, sex and relevant sociodemographic factors. No associations were found between brain morphology (ages 10 and 14) and early alcohol/tobacco use initiation (<13 years). Sex-specific analyses suggested a cross-sectional association between smaller brain volume and early initiated tobacco use in girls. Our findings are important for interpreting studies examining neural consequences of substance use in the general population. Future longitudinal studies are needed to specify whether these findings can be extended to initiation and continuation of alcohol/tobacco use in later stages of adolescence.

RESUMO

Background and aims: The aim of the present study was to estimate the complex association between Internet Gaming Disorder (IGD), substance use, and other risky behaviours in Czech adolescents whilst providing prevalence estimates of IGD and psychometric information regarding the Czech Internet Gaming Disorder Scale-Short-Form (IGDS9-SF). Methods: A representative sample of 3,950 Czech adolescents was recruited through stratified random sampling in the school setting. Results: Disordered gamers showed frequent use of specific substances such as pharmaceuticals, methylenedioxymethamphetamine, and lysergic acid diethylamide. In contrast, non-gamers had higher prevalence of alcohol, cigarettes, sedatives and tranquillisers, and marijuana use. A logistic regression, utilising IGDS9-SF raw scores and average daily gaming time, revealed a U-shaped relationship between gaming and both alcohol and cigarette use. Additionally, conduct problems such as bullying, and risky in-game behaviours were more prevalent among disordered gamers, with the exception of forging parents' signatures. The overall prevalence of IGD was 3.62% (95% CI = [3.1%, 4.3%]), with higher rates in males (5.89%; 95% CI = [4.9%, 7.0%]) than in females (1.45%; 95% CI = [1.0%, 2.1%]). Discussion and conclusions: The Czech IGDS9-SF used in the present study showed adequate psychometric properties. The association between gaming and substance use behaviours may be specific and multifaceted depending on the severity of the gaming-related problems. Furthermore, disordered gamers may become more vulnerable due to a higher incidence of conduct problems, bullying (victimisation), and in-game risky behaviours such as engagement with microtransactions mechanics (e.g., loot box) within video games.

RESUMO

OBJECTIVE: To analyze the relevance of a set of clinical elements to represent the content domain of the nursing diagnosis Ineffective Protection. DESIGN AND METHODS: This study employed content validation, using expert judgment to assess the appropriateness of clinical indicators, etiological factors, and conceptual and operational definitions, integrating the collective wisdom framework, the theory of predictive diversity, and the determination of rater skill level. RESULTS: From the middle range theory, 28 clinical indicators and 17 etiological factors were identified, which were rated by 34 raters. The analysis showed that the clinical indicators restlessness and insomnia and the etiological factors ambient temperature and humidity were not considered relevant for the nursing diagnosis of Ineffective Protection, because the median content validity index was lower than 0.9. CONCLUSIONS: Content validation verified that most of the components of the nursing diagnosis of Ineffective Protection were considered relevant by judges. PRACTICAL IMPLICATIONS: It is believed that the data obtained can help nurses to more easily evaluate the related factors and clinical indicators of Ineffective Protection presented by adolescents with cancer, which favors the process of diagnostic inference.

RESUMO

OBJECTIVES: The overarching aim of this study is to explore, examine and identify the experience that young women with congenital heart disease face as they transition through adolescence into womanhood. DESIGN: This is an empirical qualitative study conducted in the form of three focus groups. The study design and analysis adopted a feminist ontological positioning to elucidate the voice of women and offer an alternative perspective of cardiology health care. Data were analysed using the inductive thematic approach informed by the study aims. PARTICIPANTS: A group of seven female participants (mean age 26) based in the United Kingdom, each with varying degrees of congenital heart defects that required open heart surgery growing up, was included in the study. RESULTS: Three key themes with antecedent concepts emerged: (a) the impact of womanhood and the potential influence of motherhood on the young women themselves transitioning through adolescence with CHD within medical and sociocultural contexts, (b) the challenges of being a woman and undergoing heart surgery during adolescence on the young women's health before, during and after surgery and (c) the effect of existing online/offline healthcare and social structures on women's health during transitioning through adolescence These themes were encompassed under an overarching theme of psychological complexities developed throughout the cardiac journey from diagnosis through to post-surgery. CONCLUSION: This study built on the limited exploration of being a young woman and having CHD and confirmed that there are vulnerabilities and challenges in having CHD as a young woman transitioning through adolescence. This was a result of sex (biological characteristics) and gender factors (socially constructed roles). This leads to short- and long-term implications on psychological well-being. This research indicates that enhancements are needed in the provision of care and psychological support for young women with CHD. This will help to enable women to achieve a good quality of life in addition to increased life expectancy offered by medical advancements. PATIENT OR PUBLIC CONTRIBUTION: Active participant involvement was crucial to ensure the authentic female voice in the study. This study received support from young women with congenital heart disease. Young women contributed to the study design, recruitment of participants and analysis of results. Two of the women were also co-authors of this paper.

RESUMO

PURPOSE: Current literature on prevention and intervention programs for European adolescents who engage in health risk behaviors is limited. Few studies have utilized latent profile analysis methods and internationally comparative data on adolescents and their health risk behaviors, highlighting the need for more comprehensive research using internationally comparative data. The current study aimed to examine the health risk behavior profiles and identify subgroups of adolescents with similar patterns of health risk behaviors using a representative sample of European countries. Findings will inform better targeted prevention strategies for this population. METHODS: The study used a quantitative approach and implemented secondary data analysis using the Health Behavior in School-Aged Children survey 2017/2018 from 43 European countries to understand the prevalence of health risk behaviors among European adolescents and yield latent profiles regarding their health risk behaviors by sex. RESULTS: Five latent profiles of health risk behaviors were identified for boys and six for girls. For both boys and girls, low-risk (83.4% and 85.7%), poor lifestyle, smoking (6.2% and 5.1%), balanced lifestyle, aggressive acts (5.4% and 3.7%), poor lifestyle, high substance use (2% and 1%), moderate lifestyle, and moderate substance use (3% and 0.9%) were common profiles. A moderate lifestyle and low substance use profile (3.6%) was only specific to girls. DISCUSSION: The current study provides important insights regarding European adolescents' health risk behaviors. The findings suggest the need for better targeted prevention programming.

RESUMO

BACKGROUND: Adolescent substance use (SU) is often motivated by a desire to alleviate undesirable symptoms. To test the self-medication hypothesis, we examined associations between comorbid psychologic and somatic symptom trajectories across early adolescence and early onset SU. METHODS: Using Adolescent Brain Cognitive Development Study® data, we differentiated youth who reported no SU at baseline based on their comorbid anxiety, depression, pain, somatic and somnolence symptom trajectories. The outcome, early onset SU (by age 13-14 years) was derived from self-reported alcohol (≥full drink), tobacco (full regular/e-cigarette), marijuana, or other drug use over 5 years. RESULTS: 8311 participants were classified with Asymptomatic (27.8 %), Low/stable (39 %), Moderate/persistent (25.3 %) or High/worsening trajectories (7.9 %) from age 9.97 ± 0.74 to 13.57 ± 0.88 years. Early onset SU was 56 % higher for Moderate-High compared to Asymptomatic-Low symptom trajectory groups (12.5 % vs. 8.5 %; OR 1.56 [95 % CI 1.33, 1.79]). Adjusted for covariates, the High/worsening group was more likely than the Asymptomatic group to report use of any substance (adj.OR 2.13 [95 % CI 1.40, 3.25], Alcohol (adj.OR 2.80 [95 % CI 1.56, 5.02]), Tobacco (adj.OR 2.09 [95 % CI 1.23, 3.55]), and Marijuana (adj.OR 2.33 [95 % CI 1.36, 3.99]). Longitudinal, time-lagged analyses revealed potential feedback effects of earlier depression on subsequent SU, and earlier SU on later depression (p < 0.001). CONCLUSION: Higher comorbid symptom trajectories emerging in late childhood increased the likelihood of early onset SU. Since negative feedback loops may contribute to symptom persistency, ongoing and potentially harmful SU for at-risk youth, addressing comorbid symptoms that emerge during late childhood is warranted.

RESUMO

OBJECTIVE: Aim of the work is to increase the effectiveness of complex treatment in patients with mesial occlusion during active skeletal growth. mproving the effectiveness of complex treatment of patients with mesial occlusion during active skeletal growth. MATERIAL AND METHODS: Clinical and radiological examination and comprehensive treatment of 30 patients with skeletal anomalies according to sagittale were carried out (average age 15 years). Orthodontic treatment of patients was performed using the Damon self-ligating bracket system («Ormco¼, USA), H4 («OC Orthodontics¼ USA) with a sequential change of arches. According to the indications, orthodontic mini screws, removable, non-removable dilators, a facial mask, occlusal pads for disconnecting the bite, in the retention period, non-removable retainers in the anterior part of the dentition, a removable retention device at night «Corrector¼, or removable plate devices were used. RESULTS: Rapid palatal expansion was performed according to the traditional method, based on the stages of formation of the median palatine suture (the first algorithm is the stage of formation of the palatine suture A-B). In patients with narrowing of the HF with the stage of formation of the median palatine suture C, the beginning of stage D, the use of the proposed expansion scheme with the use of piezocorticotomy to eliminate the buttresses of the upper jaw, the use of laser corticotomy and the protocol of activation and deactivation of the screw to relax the bone and achieve skeletal expansion of the upper jaw was effective. The change in the dental alveolar height, normalization of the incisor overlap height improved harmony in the gnatic part of the facial skull of patients. In the process of orthodontic treatment, the inclination of the occlusal plane was normalized, the profile of the face improved. Changes in the soft tissues of the profile consisted in an increase in the thickness of the upper lip by 2.27±0.48 mm (p<0.05) and its length by 1.45±0.39 mm (p<0.05), the total length of the lower lip and chin by 3.16±0.45 mm (p<0.05). The position of the lips relative to the aesthetic plane has changed most significantly. An algorithm was developed for the treatment of patients with dental anomalies in the sagittal plane, with a narrowing of the upper jaw during the bite of permanent teeth 12-17 years. CONCLUSION: The method of complex treatment is designed to increase the effectiveness of orthodontic treatment of patients with skeletal abnormalities during active skeletal growth and is aimed at changing skeletal growth, as well as to prevent the development of skeletal malocclusion during permanent bite, which is necessary to prevent the development of more pronounced skeletal deformity at the stage of complete skeletal maturation.

RESUMO

BACKGROUND: Up to 50% of adolescents who undergo metabolic and bariatric surgery (MBS) have obesity 3 years post-MBS, placing them at continued risk for the consequences of obesity. OBJECTIVES: We conducted an open-label, 16-week pilot study of liraglutide in adolescents with obesity after sleeve gastrectomy (SG) to investigate liraglutide effects on weight and body mass index (BMI) post-SG. METHODS: Adolescents aged 12-20.99 years with obesity and a history of SG ≥1 year prior were enrolled. Liraglutide was initiated at 0.6 mg/day, escalated weekly to a maximum of 3 mg/day, with treatment duration 16 weeks. Fasting laboratory assessments and an oral glucose tolerance test were performed at baseline and end-treatment. RESULTS: A total of 43 participants were screened, 34 initiated liraglutide (baseline BMI 41.2 ± 7.7 kg/m2), and 31 (91%) attended the end-treatment visit. BMI decreased by 4.3% (p < 0.001) with liraglutide. Adolescents who had poor initial response to SG (<20% BMI reduction at BMI nadir) had less weight loss with liraglutide. Fasting glucose and haemoglobin A1C concentrations significantly decreased. There were no serious treatment-emergent adverse events reported. CONCLUSIONS: Liraglutide treatment was feasible and associated with a BMI reduction of 4.3% in adolescents who had previously undergone SG, quantitatively similar to results obtained in adolescents with obesity who have not undergone MBS.

RESUMO

Background: Liver cancer is a significant contributor to the global disease burden, of which hepatoblastomas are the most common liver tumors in children, with 90% of cases occurring within the first 5 years of life. It is important for pediatricians and subspecialists in pediatric gastroenterology and hepatology to have knowledge of the epidemiology and incidence trends of pediatric hepatic cancer, despite its rarity. In the present study, we first provide estimates of the incidence and mortality burden of hepatoblastoma and liver cancer from 2000 to 2021 in the childhood and adolescence. Methods: Liver cancer burden and its attributable risk factors were estimated using data from the Global Burden of Disease Study (GBD) 2021. Percentage change was estimated to show the trend of liver cancer estimates from 2000 to 2021. The age-standardized rate (ASR) and estimated annual percentage change (EAPC) were utilized for measuring hepatoblastomas incidence and deaths rate trends. In accordance with the GBD framework, 95% uncertainty intervals (UIs) for all estimates by averaging the data from 1000 draws, with the lower and upper bounds of the 95% UIs. Findings: Globally, from 2000 to 2021 in the age 5-19 years group, the incidence cases and deaths cases due to liver cancer decreased from 2449.2 (95% UI: 2235.9-2689.8) to 1692.9 (95% UI: 1482.0-1992.5) and 2248.5 (95% UI: 2053.7-2474.9) to 1516.6 (95% UI: 1322.1-1797.9), respectively. Meanwhile, from 2000 to 2021 in the age 20-24 years group, the incidence cases and deaths cases due to liver cancer decreased from 1453.5 (95% UI: 1327.8-1609.4) to 1285.1 (95% UI: 1159.2-1447.2) and 1432.3 (95% UI: 1307.6-1585.7) to 1195.5 (95% UI: 1066.1-1355.2), respectively. In addition, the prevalence of liver cancer decreased from 41.9% (95% UI: 18.7%-64.7%) to 26.4% (95% UI: 14.2%-39.1%) in the age 5-19 years group, and 46.6% (95% UI: 42.8%-51.5%) to 36.5% (95% UI: 33.1%-40.9%) in the age 20-24 years. From 2000 to 2021, in the age group of 5-19 years, the proportion of liver cancer incidence due to hepatitis B has decreased from 42.2% to 37.9%, while the proportion due to hepatitis C has increased from 1.1% to 1.6%. Additionally, there has been an increase in the proportion of NASH-induced liver cancer incidence from 5.2% to 9.4%, and alcohol use induced liver cancer incidence has also increased from 0.5% to 0.7% over the same period. Globally, from 2000 to 2021, the incidence cases and deaths cases due to hepatoblastoma decreased from 6131.8 (95% UI: 5234.8-6961.9) to 4045.6 (95% UI: 3250-4995.8) and 4059.2 (95% UI: 3494.5-4621.2) to 2416 (95% UI: 1940.2-3022.5), respectively. There was some variation in age-related sex-specific patterns, the highest number of hepatoblastoma incidence cases occurred in children between 2 and 4 years old and females in the age range of 12 months to 9 years had a higher number of new cases. Importantly, the incidence of hepatoblastoma was started to increase sharply after the age of 1 month. Interpretation: The results of the present study are significant for liver health policy and practice in childhood and adolescence. Differentiated intervention and outreach strategies based on age and gender would be necessary to reduce the impact of liver cancer. Early screening and interventions for hepatoblastoma is important especially in the population of under 9 years old.

RESUMO

A 15-year-old female with Hodgkin's lymphoma underwent ovarian tissue cryopreservation for preserving fertility in Reproductive Department of Sir Run Run Shaw Hospital, Zhejiang University School of Medical after receiving one course of chemotherapy. During the ovarian tissue cryopreservation, one MⅡmature oocyte and three germinal vesicle oocytes were found. The three immature oocytes underwent in vitro maturation but failed. Ultimately, one mature oocyte and 12 ovarian cortex slices were cryopreserved using vitrification. This case indicates that for patients with established gonadal axis feedback, ovarian tissue cryopreservation may not be the only method for fertility preservation. It is advisable to consider ovarian stimulation and oocyte retrieval for oocyte cryopreservation. Alternatively, for individuals in the ovulation phase of their menstrual cycle, attempting oocyte retrieval before ovarian tissue cryopreservation to obtain mature oocytes from the natural cycle, followed by oocyte cryopreservation, may enhance the likelihood of successful fertility preservation.

RESUMO

BACKGROUND: A growing body of work has implicated inflammation in the pathogenesis of depression. As not all individuals with heightened levels of peripheral inflammation develop symptoms of depression, additional work is needed to identify other factors that catalyze the relationship between inflammation and depressive symptoms. Given that elevated levels of inflammatory activity can induce a variety of emotional changes, the present study examined whether emotional clarity, the trait-like ability to identify, discern, and express one's emotions, influences the strength of the association between inflammatory signaling and concurrent and prospective symptoms of depression. METHODS: Community adolescents (N = 225, Mage = 16.63 years), drawn from a larger longitudinal project investigating sex and racial differences in depression onset, provided blood samples to determine peripheral levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and C-reactive protein (CRP) at a baseline visit, along with self-report measures of emotional clarity and depressive symptom severity. Depressive symptom severity was assessed again at a follow-up visit approximately 5-months after baseline. RESULTS: Hierarchical multiple regressions detected a significant interaction between inflammatory markers and emotional clarity on future depression severity, controlling for baseline depressive symptoms. Specifically, among adolescents with low levels of emotional clarity, higher levels of IL-6, CRP, and inflammatory composite scores were significantly associated with greater future depression severity. CONCLUSIONS: These results indicate that low emotional clarity and high inflammatory signaling may jointly confer risk for prospective depressive symptom severity among adolescents. Therapeutic interventions that improve emotional clarity may reduce risk of depressive symptoms among adolescents with low-grade peripheral inflammation.

RESUMO

Maladaptive reactive aggression is a core symptom of neuropsychiatric disorders such as schizophrenia. While uncontrolled aggression dampens societal safety, there is a limited understanding of the neural regulation involved in reactive aggression and its treatment. High levels of aggression have been linked to low serotonin (5-HT) levels. Additionally, post-weaning socially isolated (SI) mice exhibit outbursts of aggression following encountering acute stress, and hyperactivated ventral hippocampus (vHip) involves this stress-provoked escalated aggression. Here, we investigated the potential role of the raphe nucleus projecting to the vHip in modulating aggressive behavior. Chemogenetically activating the dorsal raphe nucleus (DRN) soma projecting the vHip or DRN nerve terminals in the vHip reduced reactive aggression. The reduction of attack behavior was abolished by the pretreatment of 5-HT1B receptor antagonist SB-224289. However, activating the median raphe nucleus (MRN)-to-vHip pathway ameliorated depression-like behavior but did not affect reactive aggression. DRN→vHip activation suppressed the vHip downstream area, the ventromedial hypothalamus (VMH), which is a core aggression area. Intra-vHip infusion of 5-HT1B receptor agonists (anpirtoline, CP-93129) suppressed reactive aggression and decreased c-Fos levels in the vHip neurons projecting to the VMH, suggesting an inhibition mechanism. Our findings indicate that activating the DRN projecting to the vHip is sufficient to inhibit reactive aggression in a 5-HT1B receptor-dependent manner. Thus, targeting 5-HT1B receptor could serve as a promising therapeutic approach to ameliorate symptoms of reactive aggression.

RESUMO

BACKGROUND: Latino/a youth are at increased risk of electronic (e)-cigarette or electronic nicotine delivery systems (ENDS) use; thus, identifying factors impacting initiation is critical. Parenting practices reflecting warmth (e.g., relationship quality) and control (e.g., parental monitoring) and substance use-specific parenting (e.g., reactions to use, parenting self-efficacy) may influence youth substance use. For Latino/a youth, tensions from intergenerational acculturative differences are linked to substance use. We investigated ENDS use-specific parenting as a mediator between general parenting and youth ENDS use, examining whether acculturative gap conflict moderated the association between general and ENDS use-specific parenting. We expected mediation among families experiencing low acculturative gap conflicts. METHOD:  Data were analyzed over two waves from a predominantly White and Latino/a sample of caregiver-child dyads (N = 143) who identified with a culture in addition to or distinct from American. Youth (Mage = 14.9 years, SD = 0.67; 62.9% female) reported relationship quality, parental monitoring, caregiver ENDS attitudes and reactions, acculturative gap conflicts, and ENDS use. Caregivers reported on ENDS use-specific parenting self-efficacy. Two moderated multiple mediator regression models (i.e., relationship quality, parental monitoring) were estimated. RESULTS:  Among youth reporting low and mean levels of acculturative gap conflict, ENDS use-specific parenting self-efficacy mediated the association between relationship quality and reduced ENDS use. There was no evidence for an interaction in the parental monitoring model. CONCLUSIONS:  In families experiencing low levels of acculturative gap conflict, relationship quality may impact ENDS use through caregivers' confidence in their ability to prevent child ENDS use.
