Cell transplantation therapies for spinal cord injury focusing on bone marrow mesenchymal stem cells: Advances and challenges

Spinal cord injury (SCI) is a devastating condition with complex pathological mechanisms that lead to sensory, motor, and autonomic dysfunction below the site of injury. To date, no effective therapy is available for the treatment of SCI. Recently, bone marrow-derived mesenchymal stem cells (BMMSCs) have been considered to be the most promising source for cellular therapies following SCI. The objective of the present review is to summarize the most recent insights into the cellular and molecular mechanism using BMMSC therapy to treat SCI. In this work, we review the specific mechanism of BMMSCs in SCI repair mainly from the following aspects: Neuroprotection, axon sprouting and/or regeneration, myelin regeneration, inhibitory microenvironments, glial scar formation, immunomodulation, and angiogenesis. Additionally, we summarize the latest evidence on the application of BMMSCs in clinical trials and further discuss the challenges and future directions for stem cell therapy in SCI models.

Design and Implementation of Mental Health Consultation System for Primary and Secondary School Students Based on Credibility Matching Model

Primary and secondary schools have the enormous responsibility of developing talent over a hundred years, and they should not only be concerned with the moral, ideological, and cultural development of teenagers but also with their mental well-being. We need to start by making the external environment better, provide in-depth psychological counseling, and support students as they work to continually increase their psychological adaptability in order to promote the healthy development of their personalities. As the epidemic situation in China has now stabilized into a normal state of prevention and control, it is imperative to provide primary and secondary school students with mental health education. In light of this context, this paper develops a browser-server network architecture-based consultation system for the mental health of students in primary and secondary schools. It eliminates the conventional booking mode and substitutes credibility as the characteristic programming parameter. The performance of the original system is improved by the reliability model the most when the parameter is set to 0.2, and the recovery rate rises by 1.32 percent. Compared to the original reliability model, which improved the system’s F value performance by 0.83 percent, the accuracy rate only declines by 0.68 percent while F rises by 0.37 percent. This research is crucial for creating an information campus and raising the standard of psychological counseling.

Mental Health Surveillance Among Children - United States, 2013-2019

Mental health encompasses a range of mental, emotional, social, and behavioral functioning and occurs along a continuum from good to poor. Previous research has documented that mental health among children and adolescents is associated with immediate and long-term physical health and chronic disease, health risk behaviors, social relationships, education, and employment. Public health surveillance of children's mental health can be used to monitor trends in prevalence across populations, increase knowledge about demographic and geographic differences, and support decision-making about prevention and intervention. Numerous federal data systems collect data on various indicators of children's mental health, particularly mental disorders. The 2013-2019 data from these data systems show that mental disorders begin in early childhood and affect children with a range of sociodemographic characteristics. During this period, the most prevalent disorders diagnosed among U.S. children and adolescents aged 3-17 years were attention-deficit/hyperactivity disorder and anxiety, each affecting approximately one in 11 (9.4%-9.8%) children. Among children and adolescents aged 12-17 years, one fifth (20.9%) had ever experienced a major depressive episode. Among high school students in 2019, 36.7% reported persistently feeling sad or hopeless in the past year, and 18.8% had seriously considered attempting suicide. Approximately seven in 100,000 persons aged 10-19 years died by suicide in 2018 and 2019. Among children and adolescents aged 3-17 years, 9.6%-10.1% had received mental health services, and 7.8% of all children and adolescents aged 3-17 years had taken medication for mental health problems during the past year, based on parent report. Approximately one in four children and adolescents aged 12-17 years reported having received mental health services during the past year. In federal data systems, data on positive indicators of mental health (e.g., resilience) are limited. Although no comprehensive surveillance system for children's mental health exists and no single indicator can be used to define the mental health of children or to identify the overall number of children with mental disorders, these data confirm that mental disorders among children continue to be a substantial public health concern. These findings can be used by public health professionals, health care providers, state health officials, policymakers, and educators to understand the prevalence of specific mental disorders and other indicators of mental health and the challenges related to mental health surveillance.

Influencing Factors of Depression among Adolescent Asians in North America: A Systematic Review

Background: Asian American adolescents experience rates of depression comparable to or greater than those of other ethnic minorities. The purpose of this systematic review is to summarize psychosocial factors related to depressive symptoms of Asian American adolescents between the ages of 10 to 19. Methods: Various electronic databases were systematically searched to identify research articles published from 2000 to 2021, and the psychosocial factors influencing depression among Asian adolescents in North America were examined. Results: A total of 81 studies were included in this systematic review. Consistent findings on relationships between depressive symptoms and influencing factors included (a) acculturative stress, (b) religious or spiritual significance for females, (c) parent–child cohesion, (d) harsh parenting style, (e) responsive parenting style, (f) racial or ethnic discrimination, (g) being bullied, (h) positive mentor presence, and (i) exposure to community violence. Collectively, the majority of included studies suggest that depressive symptoms were more likely found among Asian American adolescents who (a) are older, (b) are female, (c) have immigrant status, (d) exhibit coping behaviours, (e) face academic challenges, (f) face a poor socioeconomic situation, (g) perceive parent–child conflict, (h) perceive maternal disconnectedness, and (i) perceive negative peer relations. A number of conflictive findings also existed. Discussion/Conclusions: This systematic review provides a summary of the various psychosocial factors on individual, familial, and social levels, which influenced the depressive symptoms of Asian American adolescents. Such findings offer a starting point to examine what factors should be necessarily included in related depression-preventive intervention design and evaluation. Culturally sensitive care, strengthened family–school–community collaboration, and targeted research efforts are needed to meet the needs of Asian adolescents experiencing a range of depressive symptoms.

Explaining the Asian American Youth Paradox: Universal Factors versus Asian American Family Process Among Filipino and Korean American Youth

This study used longitudinal survey data of Filipino American and Korean American youth to examine ways in which universal factors (e.g., peer antisocial behaviors and parent-child conflict) and Asian American (AA) family process variables (e.g., gendered norms) independently and collectively predict grade point average (GPA), externalizing, and internalizing problems. We aimed to explain the "Asian American youth paradox" in which low externalizing problems and high GPA coexist with high internalizing problems. We found that universal factors were extensively predictive of youth problems and remained robust when AA family process was accounted for. AA family process also independently explained youth development and, in part, the AA youth paradox. For example, gendered norms increased mental distress. Academic controls did the opposite of what it is intended, that is, had a negative impact on GPA as well as other developmental domains. Family obligation, assessed by family-centered activities and helping out, was beneficial to both externalizing and internalizing youth outcomes. Parental implicit affection, one of the distinct traits of AA parenting, was beneficial, particularly for GPA. This study provided important empirical evidence that can guide cross-cultural parenting and meaningfully inform intervention programs for AA youth.

Immigration and Language Factors Related to Depressive Symptoms and Suicidal Ideation in Asian American Adolescents and Young Adults

This study examined the effects of immigration and language factors on depressive symptoms and suicidal ideation among Asian American adolescents and young adults during three developmental periods. Using the National Longitudinal Study of Adolescent to Adult Health, linear regression and linear probability models were used for the data analyses. A significant group difference was observed in suicidal ideation between Asian American youth who were born in the U.S. and whose families spoke English at home and all other Asian American youth. Differences between ethnic groups were found in the mean scores of depressive symptoms and the probabilities of suicidal ideation between Asian American youth and non-Hispanic white (NHW) youth. The findings of this study reveal mental health disparities between Asian American youth and NHW youth in the U.S. These results emphasize the importance of implementing culturally sensitive mental health interventions for Asian American adolescents and young adults.

Risk Factors of Suicide and Depression among Asian American, Native Hawaiian, and Pacific Islander Youth: A Systematic Literature Review

Suicide has become an increasing public health challenge, with growing incidence among Asian American, Native Hawaiian, and Pacific Islander (AA and NHPI) youth. Using an ecological framework, the purpose of this systematic review was to explicate risk and protective factors for depression or suicide among AA and NHPI youth from available peer reviewed research. The ecological framework provides a useful blueprint for translating social determinants of health to explain the experience of depression and suicidal behaviors among AA and NHPI youth. Sixty-six studies were extracted from PsychInfo, Ovid Med-line, EMBASE, CINAHL, and Web of Science. Policy and practice recommendations are offered in light of relevant themes that emerged. Further research and data disaggregation is needed to develop and strengthen population health strategies, interventions, and policies that address the underlying social conditions and cultural contexts of mental health disparities associated with depression and suicide among AA and NHPI youth.

Understanding differences in alcohol consumption and depressed mood between U.S.- and foreign-born Asian and Caucasian college students

The number and proportion of foreign-born individuals in the U.S. population has increased in recent decades. From 1970 to 2007, the foreign-born population more than tripled to approximately 37 million (U.S. Census Bureau, 1997 , 2008 ). Foreign-born students are a key subpopulation of college students. About 23% of U.S. undergraduate college students in 2007-2008 were either born outside of the United States (10%) or were children of at least one first-generation immigrant parent (13%; National Center for Education Statistics, U.S. Department of Education [NCES], 2012 ). Asian students constitute the majority (30%) of foreign-born undergraduates. Although foreign-born Asian students compose nearly one-quarter of the college population, limited research has examined how rates of alcohol use and depression differ between foreign-born and U.S.-born Asian college students (Gonzalez, Reynolds, & Skewes, 2011 ; Ralston & Palfai, 2012 ). The limited research is worrisome given their increasing rates of college enrollment (U.S. Census Bureau, 2011 ), alcohol consumption (Aud, Fox, & KewalRamani, 2010 ), alcohol abuse and dependence (Grant et al., 2004 ), and underutilization of mental health services (U.S. Department of Health and Human Services, 2001 ). Collectively, these factors point to the need for further research tailored to Asian college drinkers.

Early risk factors for depressive symptoms among Korean adolescents: a 6-to-8 year follow-up study

Depression during adolescence is critical to the individual's own development. Hence, identifying individuals with high-risk depression at an early stage is necessary. This study aimed to identify childhood emotional and behavioral risk factors related to depressive symptoms in Korean adolescents through a longitudinal study. The first survey took place from 1998 to 2000, and a follow-up assessment conducted in 2006, as the original participants reached 13-15 yr of age. The first assessment used the Korean version of Child Behavior Checklist and a general questionnaire on family structure, parental education, and economic status to evaluate the participants. The follow-up assessment administered the Korean Children's Depression Inventory. Multiple regression analysis revealed that childhood attention problems predicted depressive symptoms during adolescence for both boys and girls. For boys, family structure also predicted adolescent depressive symptoms. This study suggests that adolescents with attention problems during childhood are more likely to experience depressive symptoms.
