Second primary cancer risks according to race and ethnicity among U.S. breast cancer survivors.

Breast cancer survivors have an increased risk of developing second primary cancers, yet risks by race and ethnicity have not been comprehensively described. We evaluated second primary cancer risks among 717,335 women diagnosed with first primary breast cancer (aged 20-84 years and survived ≥1-year) in the SEER registries using standardized incidence ratios (SIRs; observed/expected). SIRs were estimated by race and ethnicity compared with the racial- and ethnic-matched general population, and further stratified by clinical characteristics of the index breast cancer. Poisson regression was used to test for heterogeneity by race and ethnicity. SIRs for second primary cancer differed by race and ethnicity with the highest risks observed among non-Hispanic/Latina Asian American, Native Hawaiian, or other Pacific Islander (AANHPI), non-Hispanic/Latina Black (Black), and Hispanic/Latina (Latina) survivors and attenuated risk among non-Hispanic/Latina White (White) survivors (SIRAANHPI = 1.49, 95% CI = 1.44-1.54; SIRBlack = 1.41, 95% CI = 1.37-1.45; SIRLatina = 1.45, 95% CI = 1.41-1.49; SIRWhite = 1.09, 95% CI = 1.08-1.10; p-heterogeneity<.001). SIRs were particularly elevated among AANHPI, Black, and Latina survivors diagnosed with an index breast cancer before age 50 (SIRs range = 1.88-2.19) or with estrogen receptor-negative tumors (SIRs range = 1.60-1.94). Heterogeneity by race and ethnicity was observed for 16/27 site-specific second cancers (all p-heterogeneity's < .05) with markedly elevated risks among AANHPI, Black, and Latina survivors for acute myeloid and acute non-lymphocytic leukemia (SIRs range = 2.68-3.15) and cancers of the contralateral breast (SIRs range = 2.60-3.01) and salivary gland (SIRs range = 2.03-3.96). We observed striking racial and ethnic differences in second cancer risk among breast cancer survivors. Additional research is needed to inform targeted approaches for early detection strategies and treatment to reduce these racial and ethnic disparities.

Feature group partitioning: an approach for depression severity prediction with class balancing using machine learning algorithms.

In contemporary society, depression has emerged as a prominent mental disorder that exhibits exponential growth and exerts a substantial influence on premature mortality. Although numerous research applied machine learning methods to forecast signs of depression. Nevertheless, only a limited number of research have taken into account the severity level as a multiclass variable. Besides, maintaining the equality of data distribution among all the classes rarely happens in practical communities. So, the inevitable class imbalance for multiple variables is considered a substantial challenge in this domain. Furthermore, this research emphasizes the significance of addressing class imbalance issues in the context of multiple classes. We introduced a new approach Feature group partitioning (FGP) in the data preprocessing phase which effectively reduces the dimensionality of features to a minimum. This study utilized synthetic oversampling techniques, specifically Synthetic Minority Over-sampling Technique (SMOTE) and Adaptive Synthetic (ADASYN), for class balancing. The dataset used in this research was collected from university students by administering the Burn Depression Checklist (BDC). For methodological modifications, we implemented heterogeneous ensemble learning stacking, homogeneous ensemble bagging, and five distinct supervised machine learning algorithms. The issue of overfitting was mitigated by evaluating the accuracy of the training, validation, and testing datasets. To justify the effectiveness of the prediction models, balanced accuracy, sensitivity, specificity, precision, and f1-score indices are used. Overall, comprehensive analysis demonstrates the discrimination between the Conventional Depression Screening (CDS) and FGP approach. In summary, the results show that the stacking classifier for FGP with SMOTE approach yields the highest balanced accuracy, with a rate of 92.81%. The empirical evidence has demonstrated that the FGP approach, when combined with the SMOTE, able to produce better performance in predicting the severity of depression. Most importantly the optimization of the training time of the FGP approach for all of the classifiers is a significant achievement of this research.

B cells migrate into remote brain areas and support neurogenesis and functional recovery after focal stroke in mice.

Lymphocytes infiltrate the stroke core and penumbra and often exacerbate cellular injury. B cells, however, are lymphocytes that do not contribute to acute pathology but can support recovery. B cell adoptive transfer to mice reduced infarct volumes 3 and 7 d after transient middle cerebral artery occlusion (tMCAo), independent of changing immune populations in recipient mice. Testing a direct neurotrophic effect, B cells cocultured with mixed cortical cells protected neurons and maintained dendritic arborization after oxygen-glucose deprivation. Whole-brain volumetric serial two-photon tomography (STPT) and a custom-developed image analysis pipeline visualized and quantified poststroke B cell diapedesis throughout the brain, including remote areas supporting functional recovery. Stroke induced significant bilateral B cell diapedesis into remote brain regions regulating motor and cognitive functions and neurogenesis (e.g., dentate gyrus, hypothalamus, olfactory areas, cerebellum) in the whole-brain datasets. To confirm a mechanistic role for B cells in functional recovery, rituximab was given to human CD20+ (hCD20+) transgenic mice to continuously deplete hCD20+-expressing B cells following tMCAo. These mice experienced delayed motor recovery, impaired spatial memory, and increased anxiety through 8 wk poststroke compared to wild type (WT) littermates also receiving rituximab. B cell depletion reduced stroke-induced hippocampal neurogenesis and cell survival. Thus, B cell diapedesis occurred in areas remote to the infarct that mediated motor and cognitive recovery. Understanding the role of B cells in neuronal health and disease-based plasticity is critical for developing effective immune-based therapies for protection against diseases that involve recruitment of peripheral immune cells into the injured brain.

Discrimination, acculturative stress, alcohol use and their associations with alcohol-related consequences among Latino immigrant men.

Latino immigrant men are at increased risk for unhealthy alcohol use and related consequences due to social stressors associated with immigration. We assessed the associations of, and examined whether social stressors moderated associations between, alcohol use and alcohol-related consequences in a community-based sample of Latino immigrant men in Washington (N = 187). The mean Alcohol Use Disorders Identification Test Consumption (AUDIT-C) score was 6.3 (scores ≥ 4 indicate unhealthy alcohol use). More than half of the men (61.5%) reported experiencing discrimination in at least one setting and mean acculturative stress score was 18.3 indicating moderate levels of acculturative stress. Linear regression models were fit to assess main effects (associations between both alcohol use and social stressors and alcohol-related consequences) and moderation (whether the association between alcohol use and consequences varied based on experience of social stressors using multiplicative interaction) after adjustment for potential confounders. Alcohol use (ß = 0.47, 95% CI = 0.20-0.73; p = .001), discrimination (ß = 0.85, 95% CI = 0.27-1.43; p = .004), and acculturative stress (ß = 0.13, 95% CI = 0.02-0.24; p = .025) were all associated with increased experience of alcohol-related consequences. The association between alcohol use and alcohol-related consequences was stronger for those with high levels of acculturative stress (p = .025) but not experience of discrimination (p = .587). Findings underscore the importance of social and cultural context in alcohol use and related consequences. Efforts to reduce negative consequences of drinking may include focus on reducing exposure to discrimination and acculturative stress.

Dammarane triterpenes targeting α-synuclein: biological activity and evaluation of binding sites by molecular docking.

Parkinson's disease (PD) is a neurodegenerative disorder that affects adult people whose treatment is palliative. Thus, we decided to test three dammarane triterpenes 1, 1a, 1b, and we determined that 1 and 1a inhibit ß-aggregation through thioflavine T rather than 1b. Since compound 1 was most active, we determined the interaction between α-synuclein and 1 at 50 µM (Kd) through microscale thermophoresis. Also, we observed differences in height and diameter of aggregates, and α-synuclein remains unfolded in the presence of 1. Also, aggregates treated with 1 do not provoke neurites' retraction in N2a cells previously induced by retinoic acid. Finally, we studied the potential sites of interaction between 1 with α-synuclein fibrils using molecular modelling. Docking experiments suggest that 1 preferably interact with the site 2 of α-synuclein through hydrogen bonds with residues Y39 and T44.

Quality of Life and Pain Experienced by Children and Adolescents With Cancer at Home Following Discharge From the Hospital.

An exploratory study was conducted to examine the quality of life and pain experienced by patients with pediatric cancer at home after discharge. Physical, cognitive, social, and emotional aspects of quality of life were measured and how these may be affected by age, sex, diagnosis, and pain status. The authors also characterized intensity, location, and quality of pain experienced. A sample of 33 patients participating in a larger study was selected on the basis of having pain on the day of discharge and having completed the Pediatric Quality of Life Inventory Generic, Cancer Module, Multidimensional Fatigue Scale, and the Adolescent Pediatric Pain Tool at home. Cancer diagnoses were leukemias/lymphomas (42.4%), brain/central nervous system tumors (27.3%), sarcomas (24.2%), or other (6.1%). More than half of patients reported pain (n=17; 51.5%). Patients with pain had more fatigue affecting the quality of life (P=0.01), and lower physical and emotional functioning, leading to lower overall health-related quality of life scores (P=0.011). Female individuals and adolescents reported worse emotional functioning (P=0.02 and P=0.05, respectively). Physical, cognitive, and social functioning were lowest among patients diagnosed with sarcomas (P=0.00, P=0.01, and P=0.04, respectively). It is important to understand the symptom experience of patients at home as a first step in moving towards optimal discharge teaching and treatment.

Participant engagement in a community based participatory research study to reduce alcohol use among Latino immigrant men.

Although Latino immigrant men experience many health disparities, they are underrepresented in research to understand and address disparities. Community Based Participatory Research (CBPR) has been identified to encourage participant engagement and increase representation in health disparities research. The CBPR conceptual model describes how partnership processes and study design impact participant engagement in research. Using this model, we sought to describe how these domains influenced participant engagement in a pilot randomized controlled trial of brief intervention for unhealthy alcohol use (n = 121) among Latino immigrant men. We conducted interviews with a sample of study participants (n = 25) and reviewed logs maintained by 'promotores'. We identified facilitators of participant engagement, including the relevance of the study topic, alignment with participants' goals to improve their lives, partnerships with study staff that treated participants respectfully and offered access to resources. Further, men reported that the study time and location were convenient and that they appreciated being compensated for their time. Barriers to participant engagement included survey questions that were difficult to understand and competing demands of work responsibilities. Findings suggest that engaging underserved communities requires culturally responsive and community engagement strategies that promote trust. Future studies should further investigate how CBPR partnership processes can inform intervention research.

A Pilot Study Identifying Brain-Targeting Adaptive Immunity in Pediatric Extracorporeal Membrane Oxygenation Patients With Acquired Brain Injury.

OBJECTIVES: Extracorporeal membrane oxygenation provides short-term cardiopulmonary life support, but is associated with peripheral innate inflammation, disruptions in cerebral autoregulation, and acquired brain injury. We tested the hypothesis that extracorporeal membrane oxygenation also induces CNS-directed adaptive immune responses which may exacerbate extracorporeal membrane oxygenation-associated brain injury. DESIGN: A single center prospective observational study. SETTING: Pediatric and cardiac ICUs at a single tertiary care, academic center. PATIENTS: Twenty pediatric extracorporeal membrane oxygenation patients (0-14 yr; 13 females, 7 males) and five nonextracorporeal membrane oxygenation Pediatric Logistic Organ Dysfunction score matched patients INTERVENTIONS:: None. MEASUREMENTS AND MAIN RESULTS: Venous blood samples were collected from the extracorporeal membrane oxygenation circuit at day 1 (10-23 hr), day 3, and day 7 of extracorporeal membrane oxygenation. Flow cytometry quantified circulating innate and adaptive immune cells, and CNS-directed autoreactivity was detected using an in vitro recall response assay. Disruption of cerebral autoregulation was determined using continuous bedside near-infrared spectroscopy and acquired brain injury confirmed by MRI. Extracorporeal membrane oxygenation patients with acquired brain injury (n = 9) presented with a 10-fold increase in interleukin-8 over extracorporeal membrane oxygenation patients without brain injury (p < 0.01). Furthermore, brain injury within extracorporeal membrane oxygenation patients potentiated an inflammatory phenotype in adaptive immune cells and selective autoreactivity to brain peptides in circulating B cell and cytotoxic T cell populations. Correlation analysis revealed a significant relationship between adaptive immune responses of extracorporeal membrane oxygenation patients with acquired brain injury and loss of cerebral autoregulation. CONCLUSIONS: We show that pediatric extracorporeal membrane oxygenation patients with acquired brain injury exhibit an induction of pro-inflammatory cell signaling, a robust activation of adaptive immune cells, and CNS-targeting adaptive immune responses. As these patients experience developmental delays for years after extracorporeal membrane oxygenation, it is critical to identify and characterize adaptive immune cell mechanisms that target the developing CNS.

T and B cell subsets differentially correlate with amyloid deposition and neurocognitive function in patients with amnestic mild cognitive impairment after one year of physical activity.

Individuals with amnestic mild cognitive impairment (aMCI) experience cognitive declines in learning and memory greater than expected for normal aging, and are at a high risk of dementia. We previously reported that sedentary aMCI patients exhibited neuroinflammation that correlated with brain amyloid beta (Aß) burden, as determined by 18F-florbetapir positron emission tomography (PET). These aMCI patients enrolled in a one-year randomized control trial (AETMCI, NCT01146717) to test the beneficial effects of 12 months of moderate-to-high intensity aerobic exercise training (AET) or stretching/toning (ST) control intervention on neurocognitive function. A subset of aMCI participants had PET imaging, cognitive testing, and immunophenotyping of cerebrospinal fluid (CSF) and peripheral blood after AET or ST interventions. As adaptive immune responses were similar between AET and ST groups, we combined AET/ST into a general 'physical activity' (PA) group and compared Aß burden, cognitive function, and adaptive immune cell subsets to sedentary lifestyle before intervention. We found that PAinduced immunomodulation of CD4+ and CD8+ T cells in CSF correlated with changes in Aß burden in brain regions associated with executive function. Furthermore, after PA, cognitive scores on tests of memory, processing speed, attention, verbal fluency, and executive function were associated with increased percent representation of circulating naïve B + T cells. We review the literature on aMCI-related cognition and immune changes as they relate to exercise, and highlight how our preliminary data suggest a complex interplay between the adaptive immune system, physical activity, cognition, and Aß burden in aMCI.

Chloroquine and mefloquine resistance profiles are not related to the circumsporozoite protein (CSP) VK210 subtypes in field isolates of Plasmodium vivax from Manaus, Brazilian Amazon.

BACKGROUND: The central repetitive region (CRR) of the Plasmodium vivax circumsporozoite surface protein (CSP) is composed of a repetitive sequence that is characterised by three variants: VK210, VK247 and P. vivax-like. The most important challenge in the treatment of P. vivax infection is the possibility of differential response based on the parasite genotype. OBJECTIVES: To characterise the CSP variants in P. vivax isolates from individuals residing in a malaria-endemic region in Brazil and to profile these variants based on sensitivity to chloroquine and mefloquine. METHODS: The CSP variants were determined by sequencing and the sensitivity of the P. vivax isolates to chloroquine and mefloquine was determined by Deli-test. FINDINGS: Although five different allele sizes were amplified, the sequencing results showed that all of the isolates belonged to the VK210 variant. However, we observed substantial genetic diversity in the CRR, resulting in the identification of 10 different VK210 subtypes. The frequency of isolates that were resistant to chloroquine and mefloquine was 11.8 and 23.8%, respectively. However, we did not observe any difference in the frequency of the resistant isolates belonging to the VK210 subtypes. MAIN CONCLUSION: The VK210 variant is the most frequently observed in the studied region and there is significant genetic variability in the CRR of the P. vivax CSP. Moreover, the antimalarial drug sensitivity profiles of the isolates does not seem to be related to the VK210 subtypes.

Multi-level Intervention Program - A Quality Improvement Initiative to Decrease Central Line-Associated Bloodstream Infections in the Pediatric Acute and Hematology/Oncology Units.

INTRODUCTION: Central Venous Catheters (CVCs) are placed in pediatric patients that require frequent and/or long-term access for intravenous treatments and increase the risk for Central line-associated bloodstream infections (CLABSIs). The specific aims of the study were to evaluate adherence to the intervention components and rates of Central Line Associated Bloodstream Infections (CLABSIs) over five years. METHODS: Implementation occurred on the acute care and hematology-oncology pediatric units of a quaternary health care setting in Southern California. Adherence rates were quantified using a CVC audit sheet and CLABSI rates were obtained quarterly before, and at year 1, 2, 3, 4, 5 of implementation. RESULTS: CLABSI rates for both pediatric units decreased over the five-year period. Adherence rates were 90% to 100% on the different features of the intervention; the lowest was adherence to Patient Protective Equipment (PPE). A total of 41 incidents of hospital-acquired CLABSIs were reported the year prior to the Bug Buster Committee, which decreased steadily to 9 incidents after implementation. The quarterly CLABSI rates in the Pediatric Acute Care ranged from 2.8 to 6.6/1,000 catheter days and in Pediatric Hematology-Oncology from 2.1 to 4.3/1,000 catheter days the year prior to implementation. CONCLUSIONS: While adherence for staff remains high, parent/family adherence was low. We recommend including in the multi-level intervention, procedures targeting parent adherence such as patient education handouts, reviewing content on admission, placing signs on doors indicating PPE requirements, and promptly providing PPE to non-adherent family members.

Vida PURA: An assessment of the fidelity of promotor-delivered screening and brief intervention to reduce unhealthy alcohol use among Latino day laborers.

We assessed the fidelity of promotores conducting screening and brief intervention (SBI) to reduce unhealthy alcohol use among Latino immigrant day laborers in the Vida PURA study. We reviewed 32 audio-recorded brief interventions to assess promotor adherence to the intervention protocol and to evaluate their motivational interviewing (MI) technique with the Motivational Interviewing Treatment Integrity (MITI) 4.2.1 tool. Promotores delivered three core intervention steps in 78% of recordings and achieved basic MI competence across all domains and proficiency in 50% of measures. Our results suggest that promotores can be trained to deliver SBI in community settings with fidelity.

Influence of parity, type of delivery, and physical activity level on pelvic floor muscles in postmenopausal women.

[Purpose] The aim of the present study was to assess the influence of parity, type of delivery, and physical activity level on pelvic floor muscles in postmenopausal women. [Subjects and Methods] This was an observational analytic cross-sectional study with a sample of 100 postmenopausal women, aged between 45 and 65 years, divided into three groups according to menopausal stage: hysterectomized and early and late postmenopause. Patients were assessed for sociodemographic and gyneco-obstetric factors and subjected to a muscle strength test and perineometry. Descriptive statistics, ANOVA, Kruskal-Wallis and multiple regression were applied. [Results] The results showed homogeneity in sociodemographic and anthropometric characteristics. There was no difference in pelvic floor muscle function among the three groups. Type of delivery, parity and physical activity level showed no influence on muscle function. [Conclusion] The findings demonstrate that parity, type of delivery, and physical activity level had no influence on pelvic floor muscle pressure in postmenopausal women. One hypothesis to explain these results is the fact that the decline in muscle function in postmenopausal women is related to the female aging process.

Mediterranean Diet and Sleep Features: A Systematic Review of Current Evidence.

The prevalence of sleep disorders, characterized by issues with quality, timing, and sleep duration is increasing globally. Among modifiable risk factors, diet quality has been suggested to influence sleep features. The Mediterranean diet is considered a landmark dietary pattern in terms of quality and effects on human health. However, dietary habits characterized by this cultural heritage should also be considered in the context of overall lifestyle behaviors, including sleep habits. This study aimed to systematically revise the literature relating to adherence to the Mediterranean diet and sleep features in observational studies. The systematic review comprised 23 reports describing the relation between adherence to the Mediterranean diet and different sleep features, including sleep quality, sleep duration, daytime sleepiness, and insomnia symptoms. The majority of the included studies were conducted in the Mediterranean basin and reported a significant association between a higher adherence to the Mediterranean diet and a lower likelihood of having poor sleep quality, inadequate sleep duration, excessive daytime sleepiness or symptoms of insomnia. Interestingly, additional studies conducted outside the Mediterranean basin showed a relationship between the adoption of a Mediterranean-type diet and sleep quality, suggesting that biological mechanisms sustaining such an association may exist. In conclusion, current evidence suggests a relationship between adhering to the Mediterranean diet and overall sleep quality and different sleep parameters. The plausible bidirectional association should be further investigated to understand whether the promotion of a healthy diet could be used as a tool to improve sleep quality.

The use of technology-assisted intervention in vocabulary learning for children with autism spectrum disorder: a systematic review.

Introduction: Children with autism spectrum disorder may show delays in vocabulary development. Technology-based interventions could facilitate the teaching of different vocabulary skills; however, it is still not clear whether technology represents an added value. Methods: The current review preregistered in PROSPERO evaluates the efficacy of technology-based interventions in vocabulary learning for children with autism spectrum disorder. We selected articles published in the period 2006-2022 from five databases. Results: The results identified two group studies, one within subject design, nine single-case studies and one randomized controlled design in participants aged 0-16 years who had used technological devices to learn vocabulary. Overall, five of the 13 studies showed positive results of using technology-assisted intervention, six described mixed results, one described negative result, and one described no differences in technology-assisted intervention. The studies are divided into the categories of efficacy of technology and comparison between technology and non-technology. Discussion: In summary, technology, such as tablets and computers, might be useful tools to improve vocabulary skills in certain children with ASD. However, the various degrees of impact found in the studies we reviewed indicate that personalized assessments, acknowledgment of previous experiences, and awareness of the context of usage are essential. The contrast with nontechnological approaches highlights the necessity for more detailed studies to pinpoint the precise conditions under which technology-based interventions can offer the most advantages.

Effects of the use of a cocoon on the autonomic, motor, and regulatory systems in preterm newborns: Randomized clinical trial.

INTRODUCTION: The wrapping of the newborn in an orthopedic tubular mesh, simulating a cocoon, can allow the infant to regain the feeling of security and stability experienced in the uterus given that the movement of one of the parts of the body exerts tactile and pressure variation in others. OBJECTIVE: We aimed to evaluate the influence of an orthopedic tubular mesh, simulating a cocoon, in therapeutic positioning, on the variables of the autonomous, motor, and regulatory systems of preterm newborns. METHODS: A controlled and randomized clinical trial was conducted with preterm newborns positioned in dorsal decubitus and divided into two groups: (a) cocoon - newborns covered with an orthopedic tubular mesh, and (b) control - newborns positioned according to the sector's routine and without the use of an orthopedic mesh. During the follow-up, each newborn was placed in the position for 30 min and was recorded for a total of 2 min, once at the beginning and again at the end of the observation period. Variables related to the autonomous system (heart rate, respiratory rate, and peripheral oxygen saturation), motor system (general movements), and regulatory system (Neonatal Infant Pain Scale) were evaluated before and after the intervention. The videos were evaluated by a researcher blind to the purpose of the study, and the resulting data were analyzed using SPSS. RESULTS: Of the 40 preterm newborns evaluated (32.5 ± 1.83 weeks), 21 were female, and 20 were allocated to the cocoon group. The variables related to the autonomous, motor, and regulatory systems remained unchanged following the positioning in the cocoon, as compared to the typical positioning employed in the neonatal unit. CONCLUSION: The simulation of a cocoon, utilizing an orthopedic tubular mesh, when applied to preterm newborns admitted to a neonatal intensive care unit can contribute to maintaining low levels of stress, without altering variables of the autonomous, motor, and regulatory systems.

Incidence, in-hospital case-fatality rates, and management practices in Puerto Ricans hospitalized with acute myocardial infarction.

OBJECTIVE: There are extremely limited data on minority populations, especially Hispanics, describing the clinical epidemiology of acute coronary disease. The aim of this study is to examine the incidence rate of acute myocardial infarction (AMI), in-hospital case-fatality rate (CFR), and management practices among residents of greater San Juan (Puerto Rico) who were hospitalized with an initial AMI. METHODS: Our trained study staff reviewed and independently validated the medical records of patients who had been hospitalized with possible AMI at any of the twelve hospitals located in greater San Juan during calendar year 2007. RESULTS: The incidence rate (# per 100,000 population) of 1,415 patients hospitalized with AMI increased with advancing age and were significantly higher for older patients for men (198) than they were for women (134). The average age of the study population was 64 years, and women comprised 45% of the study sample. Evidence-based cardiac therapies, e.g., aspirin, beta blockers, ACE inhibitors/angiotensin receptor blockers, and statins, were used with 60% of the hospitalized patients, and women were less likely than men to have received these therapies (59% vs. 65%) or to have undergone interventional cardiac procedures (47% vs. 59%) (p<0.05). The in-hospital CFR increased with advancing age and were higher for women (8.6%) than they were for men (6.0%) (p<0.05). CONCLUSION: Efforts are needed to reduce the magnitude of AMI, enhance the use of evidence-based cardiac therapies, reduce possible gender disparities, and improve the short-term prognoses of Puerto Rican patients hospitalized with an initial AMI.

Co-culturing Immune Cells and Mouse-Derived Mixed Cortical Cultures with Oxygen-Glucose Deprivation to In Vitro Simulate Neuroinflammatory Interactions After Stroke.

Studying interactions between neural cells and glial cells in vitro remains an essential tool for scientists worldwide, and with the addition of oxygen-glucose deprivation (OGD) can be particularly useful for identifying mechanisms related to ischemic stroke-related injury and repair. In developing these protocols in the lab, however, we discovered the limitation of co-culturing immune cells with pure neuronal cultures as the standard media for immune cells impair neuronal growth and vice versa. Thus, we optimized a mixed cortical cell culture system that does not require the use of glial-conditioned media to support the viability and growth of neurons but can nonetheless be used to quantify neuronal survival and dendritic arborization. The following methods provide a guide as to how to culture mixed cortical cells from mouse pups (postnatal day 0-2). Additionally, we demonstrate how to co-culture mixed cortical cells with immune cells (e.g., B cells) to study neuro-immune interactions in vitro.

A parish-based multilevel cluster randomized controlled trial to reduce stigma and mental health treatment disparities among Latino communities.

Latino communities within the U.S. are disproportionately affected by persistent, high levels of untreated mental illness. Limited mental health literacy, stigma, and cultural factors are major contributors to Latino mental health treatment disparities. Although Latino individuals may be reluctant to seek out mental health professionals, they often rely on religious congregations when confronted with mental illness. However, religious congregations report major obstacles to collaborating with the mental health sector including the lack of mental health training, staffing, and resources. Strategic partnerships between religious congregations and community-based organizations can be leveraged to target sources of Latino mental health treatment disparities. The National Alliance on Mental Illness (NAMI), the nation's largest grassroots mental health organization, has developed a host of programs tailored to the different needs and segments of the community affected by mental illness, including programs designed to address culturally diverse and faith-based communities. This cluster-randomized controlled trial leverages the collective resources of NAMI and the Diocese of San Bernardino to deliver and evaluate the effectiveness of a multi-level, parish-based, intervention to decrease stigma, increase mental health literacy, and improve access to mental health services among Latino parishioners. This study will enroll 1400 participants from 14 parishes that will be randomly assigned to receive the intervention immediately or a wait-list control condition. The intervention could enrich awareness of mental health issues, shape norms about mental illness, facilitate treatment access, and add support from religious congregations to target Latino mental health disparities using culturally and faith-based tailored approaches.
