ABSTRACT

The COVID-19 pandemic wrought significant negative impacts on youth well-being, particularly among Black, Hispanic, American Indian, Alaska Native, and LGBTQ+ (Lesbian, gay, bisexual, transgender, queer or questioning) youth. The pandemic disrupted connections to family, school, and community, which are essential supports for youth mental health. Lessons learned from the pandemic suggest the role of stress and windows of opportunity to build resiliency. Drawing from a policy dialog on the youth mental health crisis conducted by 4 American Academy of Nursing Expert Panels, we present approaches to the current increase in youth mental health problems. Included is emerging literature on building youth resilience, particularly via re-establishing school and community connections. The role of families, schools, and community support is emphasized, particularly by creating a healing school environment and the pivotal role of school nurses. Recommendations include increased support for families, engaging the school nurse role, and developing school-based innovative programs to build connections and youth wellness.

ABSTRACT

School connectedness is needed to improve youth mental health. Developing a school connection is more arduous for Black youth with a history of pervasive exclusionary discipline. This narrative review discusses academic and socioemotional consequences of school removals while highlighting disparities for Black youth. A comprehensive literature search was conducted, identifying relevant studies and publications using electronic databases; results from the last ten years were preferable but older references were included if deemed important. Recommendations for elevating the influence of school nursing has been included to help mitigate disparities and racial bias, considering historical discipline trends and rising mental health needs.

ABSTRACT

Effective B cell responses such as cytokine secretion, proliferation, and Ab-specific responses are essential to clear hepatitis B virus (HBV) infection. However, HBV alters numerous immune pathways to persist in the host. B cell activity depends on activation of the innate sensor TLR9 by viral or bacterial DNA motifs. How HBV can deregulate B cell functions remains unknown. In this study, we show that HBV can enter and decrease TLR9 expression in human primary B cells. Using PBMCs from human blood donors, we show that TLR9 expression was reduced in all peripheral B cells subsets exposed to HBV. B cell function mediated by TLR9, but not TLR7, such as proliferation and proinflammatory cytokines secretion, were abrogated in the presence of HBV; however, global Ig secretion was not downregulated. Mechanistically, we show, using human myeloma B cell line RPMI 8226, that the surface Ag hepatitis B surface Ag was responsible for TLR9 dysfunction. hepatitis B surface Ag suppressed the phosphorylation and thus the activation of the transcription factor CREB, preventing TLR9 promoter activity. Finally, we corroborated our in vitro findings in a cohort of chronic HBV carriers and found that TLR9 expression and function were significantly suppressed. The effect of HBV on TLR9 activity in B cells gives insights into oncoviral immune escape strategies, providing knowledge to develop novel immunotherapeutic approaches in chronic HBV-carrier patients.

ABSTRACT

Due to the wide range of relevant biological activities and high commercial value of cynaropicrin, and aiming at developing cost-effective processes, aqueous solutions of ionic liquids (ILs) were investigated for the extraction and recovery of cynaropicrin from the leaves of Cynara cardunculus L. Both cationic (1-alkyl-3-methylimidazolium chloride) and anionic (cholinium carboxylate) surface-active ILs were investigated, as well as a wide range of conventional surfactants and molecular organic solvents, allowing us to conclude that aqueous solutions of cationic surface-active ILs display a better performance for the extraction of cynaropicrin. Operational conditions were optimized, leading to a cynaropicrin extraction yield of 3.73 wt%. The recycling of both the biomass and the solvent were further investigated to appraise the extraction media saturation and to achieve a higher cynaropicrin extraction yield (6.47 wt%). Finally, it was demonstrated that 65 wt% of the extracted cynaropicrin can be efficiently recovered by precipitation from the IL aqueous extract through the addition of water as anti-solvent, allowing us to put forward both the extraction and recovery processes of the target value-added compound from biomass followed by solvent recycling. This approach opens the door to the development of more sustainable processes using aqueous solutions of ILs instead of the volatile organic solvents commonly used in biomass processing.

ABSTRACT

The purpose of this research is to determine the effects of implementing an electronic health record on medical-surgical registered nurses' time spent in direct professional patient-centered nursing activities, attitudes and beliefs related to implementation, and changes in level of nursing engagement after deployment of the electronic health record. Patient-centered activities were categorized using Watson's Caritas Processes and the Relationship-Based Care Delivery System. Methods included use of an Attitudes and Beliefs Assessment Questionnaire, Nursing Engagement Questionnaire, and Rapid Modeling Corporation's personal digital assistants for time and motion data collection. There was a significant difference in normative belief between nurses with less than 15 years' experience and nurses with more than 15 years' experience (t21 = 2.7, P = .01). While nurses spent less time at the nurses' station, less time charting, significantly more time in patients' rooms and in purposeful interactions, time spent in relationship-based caring behavior categories actually decreased in most categories. Nurses' engagement scores did not significantly increase. These results serve to inform healthcare organizations about potential factors related to electronic health record deployment which create shifts in nursing time spent across care categories and can be used to explore further patient centered care practices.

ABSTRACT

Asthma morbidity and mortality is higher among older school-age children and early adolescents than other age groups across the lifespan. NIH recommended expanding asthma education to schools and community settings to meet cognitive outcomes that have an impact on morbidity and mortality. Guided by the acceptance of asthma model, an evidence-guided, comprehensive school-based academic health education and counseling program, Staying Healthy-Asthma Responsible & Prepared™ (SHARP), was developed. The program complements existing school curricula by integrating biology, psychology, and sociology content with related spelling, math, and reading and writing assignments. Feasibility, benefits, and efficacy have been established. We compared the effectiveness of SHARP to a non-academic program, Open Airways for Schools, in improving asthma knowledge and reasoning about symptom management. A two-group, cluster-randomized, single-blinded design was used with a sample of 205 students in grades 4-5 with asthma and their caregivers. Schools were matched prior to randomization. The unit of analysis was the student. Certified elementary school teachers delivered the programs during instructional time. Data were collected from student/caregiver dyads at baseline and at 1, 12, and 24 months after the intervention. In multilevel modeling, students enrolled in the academic SHARP program demonstrated significant (p< .001) improvement in asthma knowledge and reasoning over students enrolled in the non-academic program. Knowledge advantages were retained at 24 months. Findings support delivery in schools of the SHARP academic health education program for students with asthma.

ABSTRACT

Childhood emotional abuse (CEA) is a pervasive problem associated with negative sequelae such as elevated depressive symptoms. Key stress-related genes, such as the 5-HTTLPR polymorphism, interact with childhood abuse to produce elevated depressive symptoms in older adolescent girls, but not in older adolescent boys. To date, studies have not examined this relationship as a function of CEA specifically or among younger adolescents. To extend prior work, we examined the effects of the 5-HTTLPR and CEA on depressive symptoms among 10-12-year-old youth. Based on previous findings, we expected a main effect of CEA on depressive symptoms among all youth, but only expected an interactive effect between the 5-HTTLPR and CEA on depressive symptoms in girls. In the current study, 222 youth (mean age 11.02 years, 44.1% girls, 51.6% Caucasian, 33.0% African American, 2.7% Latino, and 12.7% other) and their parent(s)/guardian(s) completed the Revised Child Anxiety and Depression Scale and the Emotional Abuse subscale of the Childhood Trauma Questionnaire and provided saliva samples for genotyping the 5-HTTLPR. Results indicate that CEA, but not the 5-HTTLPR, was related to elevated depressive symptoms among boys. Among girls, each copy of the s allele of the 5-HTTLPR was related to increased depressive symptoms, but only for those who had experienced CEA. Our results extend prior findings by specifically examining CEA and by focusing on 10-12-year-old youth. These results, although preliminary, suggest that focusing on the interplay between putative genetic markers and a broader range of environmental events, such as CEA, might allow researchers to determine factors differentially influencing the later emergence of sex differences in depressive symptoms.

ABSTRACT

Tryptophan (TRP) is essential for many physiological processes, and its metabolism changes in some diseases such as infection and cancer. The most studied aspects of TRP metabolism are the kynurenine and serotonin pathways. A minor metabolic route, tryptamine and N,N-dimethyltryptamine (DMT) biosynthesis, has received far less attention, probably because of the very low amounts of these compounds detected only in some tissues, which has led them to be collectively considered as trace amines. In a previous study, we showed a metabolic interrelationship for TRP in melanoma cell lines. Here, we identified DMT and N,N-dimethyl-N-formyl-kynuramine (DMFK) in the supernatant of cultured SK-Mel-147 cells. Furthermore, when we added DMT to the cell culture, we found hydroxy-DMT (OH-DMT) and indole acetic acid (IAA) in the cell supernatant at 24 h. We found that SK-Mel-147 cells expressed mRNA for myeloperoxidase (MPO) and also had peroxidase activity. We further found that DMT oxidation was catalyzed by peroxidases. DMT oxidation by horseradish peroxidase, H2O2 and MPO from PMA-activated neutrophils produced DMFK, N,N-dimethyl-kynuramine (DMK) and OH-DMT. Oxidation of DMT by peroxidases apparently uses the common peroxidase cycle involving the native enzyme, compound I and compound II. In conclusion, this study describes a possible alternative metabolic pathway for DMT involving peroxidases that has not previously been described in humans and identifies DMT and metabolites in a melanoma cell line. The extension of these findings to other cell types and the biological effects of DMT and its metabolites on cell proliferation and function are key questions for future studies.

ABSTRACT

BACKGROUND: Biobehavioural research methodology can be invasive and burdensome for participants - particularly adolescents with mental illnesses. Human biological researchers should consider how methodological impositions may hinder adolescent research participation. However, literature on adolescent's voices and concerns toward biobehavioural research participation is virtually non-existent. AIM: This study was designed to determine adolescents' perceptions of participation in research involving the collection of biomarkers via blood, saliva and/or urine samples. SUBJECTS AND METHODS: Urban adolescent females (aged 12-19) receiving outpatient mental health treatment (n = 37) participated in focus groups with concurrent survey administration to explore attitudes, beliefs and willingness/intentions toward biobehavioural research participation. RESULTS: Participants had favourable attitudes toward biobehavioural research and were amenable to provide each specimen type. Mistrust for research emerged, however, and concerns related to privacy and confidentiality were expressed. CONCLUSION: Participant recruitment is a critical component in study design and implementation; this includes knowledge of population-specific recruitment barriers and facilitators. This innovative paper provides a context for the research participants' decision-making process, strategies to allay fears and concerns and concrete areas to target in research-related interventions. Although the findings are from a specific, US-based sample, the implications warrant replication of the research in other geosocial settings.

ABSTRACT

OBJECTIVE: The goal of this study was to monitor imatinib mesylate therapeutically in the Tumor Biology Laboratory, Department of Hematology and Hemotherapy, Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo (USP). A simple and sensitive method to quantify imatinib and its metabolite (CGP74588) in human serum was developed and fully validated in order to monitor treatment compliance. METHODS: The method used to quantify these compounds in serum included protein precipitation extraction followed by instrumental analysis using high performance liquid chromatography coupled with mass spectrometry. The method was validated for several parameters, including selectivity, precision, accuracy, recovery and linearity. RESULTS: The parameters evaluated during the validation stage exhibited satisfactory results based on the Food and Drug Administration and the Brazilian Health Surveillance Agency (ANVISA) guidelines for validating bioanalytical methods. These parameters also showed a linear correlation greater than 0.99 for the concentration range between 0.500 µg/mL and 10.0 µg/mL and a total analysis time of 13 minutes per sample. This study includes results (imatinib serum concentrations) for 308 samples from patients being treated with imatinib mesylate. CONCLUSION: The method developed in this study was successfully validated and is being efficiently used to measure imatinib concentrations in samples from chronic myeloid leukemia patients to check treatment compliance. The imatinib serum levels of patients achieving a major molecular response were significantly higher than those of patients who did not achieve this result. These results are thus consistent with published reports concerning other populations.

ABSTRACT

Purpose. Relational aggression, rumor spreading, backstabbing, and social isolation, is psychologically damaging for adolescent girls. The purpose of this study was to provide an explanation of victimization response after experiencing peer relational aggression victimization. Methods. Grounded theory techniques were used to gain an understanding of the victimization experience and the coping responses used. Findings. A theory of coping after experiencing peer relational aggression victimization was generated. Girls voiced feelings of hurt and anger after the experience and expressed the following ways of coping as a result: distancing from others, retaliation against the aggressor, discussing their feelings with friends and family, writing their feelings down, and/or confronting the aggressor. Clinical Implications. Nurses should be aware of the phenomenon and asses, for incidences of relational aggression victimization so that they may provide strategies to assist the adolescent and her family with positive coping mechanisms in order to prevent maladaptive responses.

ABSTRACT

Scholars in nursing science have long espoused the concept of health equity without specifically using the term or dialoguing about the social determinants of health and social justice. This article describes the development, implementation, and evaluation of a doctoral and postdoctoral seminar collective entitled "Health Equity: Conceptual, Linguistic, Methodological, and Ethical Issues." The course enabled scholars-in-training to consider the construct and its nuances and frame a personal philosophy of health equity. An example of how a group of emerging scholars can engage in the important, but difficult, discourse related to health equity is provided. The collective provided a forum for debate, intellectual growth, and increased insight for students and faculty. The lessons learned by all participants have the potential to enrich doctoral and postdoctoral scientific training in nursing science and may serve as a model for other research training programs in the health sciences.

ABSTRACT

PROBLEM: This study aimed to examine if the experience of peer relational aggression victimization (PRAV) can be linked to feelings of depression in the African American adolescent female population. METHODS: The sample included 241 college-age African American adolescent females assessed for PRAV and depression. Statistical analysis was carried out to determine the relationship between the variables. FINDINGS: PRAV in this study population does exist as a detrimental phenomenon, whereby PRAV significantly correlates with depression, r (214) = 0.29, p < .01. CONCLUSION: Nurses can assist the adolescent clients experiencing relational aggression by becoming knowledgeable on the presentation and manifestations of this experience.

ABSTRACT

Os efeitos tóxicos mais imediatos de uma intoxicação por organofosforados ou carbamatos devem-se à inibição das colinesterases (ChES). Contudo, as faixas de variação de atividade tanto interindividual como intraindividual das ChEs são muito largas o que dificulta a interpretação dos resultados da atividade das ChEs de trabalhadores expostos a organofosforados e carbamatos. Utilizando-se o método de Nabb & Whitfield (1967) para analisar sangue de 48 trabalhadores, os resultados mostraram que a colinesterase eritrocitária (ChE-Er) variou de 10,1 a 19,7 μmol/min/mL e a colinesterase plasmática (ChE-PI) de 2,2 a 6,9 μmol/min/ML. Apesar de grande variação interindividual, com a linha de base pré-exposição que utiliza a variação intraindividual foi possível correlacionar sintomas de intoxicação leve a exposição ocupacional ao carbamato, com queda na atividade da ChE-Er menor que 30% da atividade da linha de base pré-exposição...
