HIV-1 Tat regulation of dopamine transmission and microglial reactivity is brain region specific.

The transactivator of transcription protein, HIV-1 Tat, is linked to neuroAIDS, where degeneration of dopamine neurons occurs. Using a mouse model expressing GFAP-driven Tat protein under doxycycline (Dox) regulation, we investigated microglial-neuronal interactions in the rostral substantia nigra pars compacta (SNc). Immunohistochemistry for microglia and tyrosine hydroxylase (TH) showed that the ratio of microglia to dopamine neurons is smaller in the SNc than in the ventral tegmental area (VTA) and that this difference is maintained following 7-day Dox exposure in wild type animals. Administration of Dox to wild types had no effect on microglial densities. In addressing the sensitivity of neurons to potentially adverse effects of HIV-1 Tat, we found that HIV-1 Tat exposure in vivo selectively decreased TH immunoreactivity in the SNc but not in the VTA, while levels of TH mRNA in the SNc remained unchanged. HIV-1 Tat induction in vivo did not alter the total number of neurons in these brain regions. Application of Tat (5 ng) into dopamine neurons with whole-cell patch pipette decreased spontaneous firing activity. Tat induction also produced a decline in microglial cell numbers, but no microglial activation. Thus, disappearance of dopaminergic phenotype is due to a loss of TH immunoreactivity rather than to neuronal death, which would have triggered microglial activation. We conclude that adverse effects of HIV-1 Tat produce a hypodopamine state by decreasing TH immunoreactivity and firing activity of dopamine neurons. Reduced microglial numbers after Tat exposure in vivo suggest impaired microglial functions and altered bidirectional interactions between dopamine neurons and microglia.

Seeding plants for long-term multiple ecosystem service goals.

The historical management of agroecological systems, such as California's rangelands, have received criticism for a singular focus on agricultural production goals, while society has shifting expectations to the supply of multiple ecosystem services from these working landscapes. The sustainability and the multiple benefits derived from these complex social-ecological systems is increasingly threatened by weed invasion, extreme disturbance, urban development, and the impacts of a rapidly changing and increasingly variable climate. California's grasslands, oak savannas, and oak woodlands are among the most invaded ecosystems in the world. Weed eradication efforts are rarely combined with seeding on these landscapes despite support for the inclusion of the practice in a weed management program. Depending on seed mix choice, cost and long-term uncertainty, especially for native seed, is an impediment to adoption by land managers. We investigated four seeding mixes (forage annual, native perennial, exotic perennial, and exotic-native perennial) to evaluate how these treatments resist reinvasion and support the delivery of simultaneous multiple ecosystem services (invasion resistance, native richness, nitrogen fixing plants, pollinator food sources, plant community diversity, forage quality, and productivity). We found the increase of exotic and native perennial cover will drive resistance to an invading weedy summer flowering forb Centaurea solstitialis but provides a mixed response to resisting invasive annual grasses. The resistance to invasion is coupled with little tradeoff in forage productivity and quality and gains in plant diversity and native cover.

HIV, Tat and dopamine transmission.

Human Immunodeficiency Virus (HIV) is a progressive infection that targets the immune system, affecting more than 37 million people around the world. While combinatorial antiretroviral therapy (cART) has lowered mortality rates and improved quality of life in infected individuals, the prevalence of HIV associated neurocognitive disorders is increasing and HIV associated cognitive decline remains prevalent. Recent research has suggested that HIV accessory proteins may be involved in this decline, and several studies have indicated that the HIV protein transactivator of transcription (Tat) can disrupt normal neuronal and glial function. Specifically, data indicate that Tat may directly impact dopaminergic neurotransmission, by modulating the function of the dopamine transporter and specifically damaging dopamine-rich regions of the CNS. HIV infection of the CNS has long been associated with dopaminergic dysfunction, but the mechanisms remain undefined. The specific effect(s) of Tat on dopaminergic neurotransmission may be, at least partially, a mechanism by which HIV infection directly or indirectly induces dopaminergic dysfunction. Therefore, precisely defining the specific effects of Tat on the dopaminergic system will help to elucidate the mechanisms by which HIV infection of the CNS induces neuropsychiatric, neurocognitive and neurological disorders that involve dopaminergic neurotransmission. Further, this will provide a discussion of the experiments needed to further these investigations, and may help to identify or develop new therapeutic approaches for the prevention or treatment of these disorders in HIV-infected individuals.

Convergent translational evidence of a role for anandamide in amygdala-mediated fear extinction, threat processing and stress-reactivity.

Endocannabinoids are released 'on-demand' on the basis of physiological need, and can be pharmacologically augmented by inhibiting their catabolic degradation. The endocannabinoid anandamide is degraded by the catabolic enzyme fatty acid amide hydrolase (FAAH). Anandamide is implicated in the mediation of fear behaviors, including fear extinction, suggesting that selectively elevating brain anandamide could modulate plastic changes in fear. Here we first tested this hypothesis with preclinical experiments employing a novel, potent and selective FAAH inhibitor, AM3506 (5-(4-hydroxyphenyl)pentanesulfonyl fluoride). Systemic AM3506 administration before extinction decreased fear during a retrieval test in a mouse model of impaired extinction. AM3506 had no effects on fear in the absence of extinction training, or on various non-fear-related measures. Anandamide levels in the basolateral amygdala were increased by extinction training and augmented by systemic AM3506, whereas application of AM3506 to amygdala slices promoted long-term depression of inhibitory transmission, a form of synaptic plasticity linked to extinction. Further supporting the amygdala as effect-locus, the fear-reducing effects of systemic AM3506 were blocked by intra-amygdala infusion of a CB1 receptor antagonist and were fully recapitulated by intra-amygdala infusion of AM3506. On the basis of these preclinical findings, we hypothesized that variation in the human FAAH gene would predict individual differences in amygdala threat-processing and stress-coping traits. Consistent with this, carriers of a low-expressing FAAH variant (385A allele; rs324420) exhibited quicker habituation of amygdala reactivity to threat, and had lower scores on the personality trait of stress-reactivity. Our findings show that augmenting amygdala anandamide enables extinction-driven reductions in fear in mouse and may promote stress-coping in humans.

Empowering the biomedical research community: Innovative SAS deployment on the All of Us Researcher Workbench.

OBJECTIVES: The All of Us Research Program is a precision medicine initiative aimed at establishing a vast, diverse biomedical database accessible through a cloud-based data analysis platform, the Researcher Workbench (RW). Our goal was to empower the research community by co-designing the implementation of SAS in the RW alongside researchers to enable broader use of All of Us data. MATERIALS AND METHODS: Researchers from various fields and with different SAS experience levels participated in co-designing the SAS implementation through user experience interviews. RESULTS: Feedback and lessons learned from user testing informed the final design of the SAS application. DISCUSSION: The co-design approach is critical for reducing technical barriers, broadening All of Us data use, and enhancing the user experience for data analysis on the RW. CONCLUSION: Our co-design approach successfully tailored the implementation of the SAS application to researchers' needs. This approach may inform future software implementations on the RW.

Chronic methamphetamine exposure produces a delayed, long-lasting memory deficit.

Methamphetamine (METH) is a highly addictive and neurotoxic psychostimulant. Its use in humans is often associated with neurocognitive impairment. Whether this is due to long-term deficits in short-term memory and/or hippocampal plasticity remains unclear. Recently, we reported that METH increases baseline synaptic transmission and reduces LTP in an ex vivo preparation of the hippocampal CA1 region from young mice. In the current study, we tested the hypothesis that a repeated neurotoxic regimen of METH exposure in adolescent mice decreases hippocampal synaptic plasticity and produces a deficit in short-term memory. Contrary to our prediction, there was no change in the hippocampal plasticity or short-term memory when measured after 14 days of METH exposure. However, we found that at 7, 14, and 21 days of drug abstinence, METH-exposed mice exhibited a deficit in spatial memory, which was accompanied by a decrease in hippocampal plasticity. Our results support the interpretation that the deleterious cognitive consequences of neurotoxic levels of METH exposure may manifest and persist after drug abstinence. Therefore, therapeutic strategies should consider short-term as well as long-term consequences of methamphetamine exposure.

Racial and ethnic differences in the association of social cohesion and social capital with HIV testing.

HIV testing rates vary by race and ethnicity. Whether social capital indicators are related to HIV testing and whether these associations differ by race or ethnicity is unknown. Multivariable analysis was used to examine whether social capital (collective engagement and civic and social participation), including social cohesion (trust in neighbors, neighbors willing to help, feelings of belongingness) were associated with testing for HIV in the past 12 months. Participants were white, Black or African American, and Hispanic/Latino adults ages 18 to 44 (N = 2823) from the general population, in Philadelphia, PA who participated in the Southeastern Pennsylvania Household Health Surveys 2010 and 2012. Overall HIV testing in this sample was 42%, and was higher among women, and Black compared to white people. Mean social capital scores were significantly highest among whites. Greater trust in neighbors was associated with lower odds of testing for HIV (adjusted Odds Ratio[aOR]:0.61, 95% CI = 0.49-0.74), and this relationship varied by race/ethnicity, with stronger inverse associations among Hispanic/Latino (aOR = 0.43, p < 0.001) and white adults (aOR = 0.50, p < -0.001) than among Black adults (aOR = 0.75, p < 0.05). Greater neighborhood belongingness (aOR = 1.31, 95% CI = 1.11-1.54) and working together to improve the neighborhood (aOR = 1.33, 95%CI = 1.03-1.73) were associated with higher odds of testing for HIV. Different indicators of social capital were associated with higher as well as lower odds of testing for HIV. These patterns did not vary statistically by race or ethnicity. HIV testing prevention interventions will need to address social capital in design and implementation strategies.

α-Synuclein stimulates a dopamine transporter-dependent chloride current and modulates the activity of the transporter.

Dysregulation of dopamine (DA) homeostasis is implicated in neurodegenerative diseases, drug addiction, and neuropsychiatric disorders. The neuronal plasma membrane dopamine transporter (DAT) is essential for the maintenance of DA homeostasis in the brain. α-Synuclein is a 140-amino acid protein that forms a stable complex with DAT and is linked to the pathogenesis of neurodegenerative disease. To elucidate the potential functional consequences of DAT/α-synuclein interaction, we explored α-synuclein modulation of DAT activity in midbrain dopaminergic neurons obtained from TH::RFP mice, immortalized DA neurons, and a heterologous system expressing DAT. We used dual pipette whole cell patch clamp recording to measure the DAT-mediated current before and after dialysis of recombinant α-synuclein into immortalized DA neurons. Our data suggest that intracellular α-synuclein induces a Na+ independent but Cl--sensitive inward current in DAT-expressing cells. This current is blocked by DAT blocker GBR12935 and is absent when heat-inactivated α-synuclein is dialyzed into these cells. The functional consequence of this interaction on DAT activity was further examined with real-time monitoring of transport function using a fluorescent substrate of DAT, 4-(4-(dimethylamino)styryl)-N-methylpyridinium (ASP+). Overexpression of α-synuclein in DAT-positive immortalized DA neurons and CHO cells expressing DAT decreased the magnitude and rate of DAT-mediated substrate uptake without a decrease in the initial binding of the substrate at the plasma membrane. Taken together our findings are consistent with the interpretation that DAT/α-synuclein interaction at the cell surface results in a DAT-dependent, Na+-insensitive, Cl-sensitive inward current with a decrease in substrate uptake, suggesting that DAT/α-synuclein interaction can modulate dopamine transmission and thus neuronal function.

Public Engagement with Biotechnology Inside and Outside the Classroom: Community-Focused Approaches.

Biotechnology offers vast benefits to the environment, animals, and human health, and contributes to improving socioeconomic conditions for the public. However, biotechnology innovations continue to trigger public concern and opposition over their potential social, health, and ecological risks. There is an opportunity to increase knowledge and acceptance of biotechnology through engagement, education, and community participation. In this perspective, we highlight crucial factors that shape the public perception of biotechnology and present opportunities for scientists to effectively communicate their ideas while engaging with local and global communities. Initiatives that seek to involve communities in design, development, and adoption processes are crucial for the successful implementation of biotechnology-based solutions.

In Parkinson's patient-derived dopamine neurons, the triplication of α-synuclein locus induces distinctive firing pattern by impeding D2 receptor autoinhibition.

Pathophysiological changes in dopamine neurons precede their demise and contribute to the early phases of Parkinson's disease (PD). Intracellular pathological inclusions of the protein α-synuclein within dopaminergic neurons are a cardinal feature of PD, but the mechanisms by which α-synuclein contributes to dopaminergic neuron vulnerability remain unknown. The inaccessibility to diseased tissue has been a limitation in studying progression of pathophysiology prior to degeneration of dopamine neurons. To address these issues, we differentiated induced pluripotent stem cells (iPSCs) from a PD patient carrying the α-synuclein triplication mutation (AST) and an unaffected first-degree relative (NAS) into dopaminergic neurons. In human-like dopamine neurons α-synuclein overexpression reduced the functional availability of D2 receptors, resulting in a stark dysregulation in firing activity, dopamine release, and neuronal morphology. We back-translated these findings into primary mouse neurons overexpressing α-synuclein and found a similar phenotype, supporting the causal role for α-synuclein. Importantly, application of D2 receptor agonist, quinpirole, restored the altered firing activity of AST-derived dopaminergic neurons to normal levels. These results provide novel insights into the pre-degenerative pathophysiological neuro-phenotype induced by α-synuclein overexpression and introduce a potential mechanism for the long-established clinical efficacy of D2 receptor agonists in the treatment of PD.

Alcohol Use Cravings as a Mediator Between Associated Risk Factors on Increased Alcohol Use among Youth Adults in New York During the COVID-19 Pandemic.

The sudden increase in alcohol use in the young adult population during the COVID-19 pandemic may be partially explained by social isolation and stress due to restricted stay-at-home orders. The goal of this study was to assess specific psychological factors (e.g., anxiety, depressive symptoms, sleep disturbances, and alcohol cravings) and COVID-19 diagnoses and their association with increased alcohol use and misuse during the COVID-19 pandemic among New York residents 18-35 years of age. Survey data were collected via Qualtrics between July 2020-October 2020. Path analyses tests were employed to test alcohol use cravings as a mediator. Among the total sample (N=575), mean age was 27.94±4.12; a majority were White non-Hispanic (66%), female (55%) and had completed a 4-year college or university degree (n = 249; 43.5%). Results revealed that alcohol use cravings was a significant mediator between sleep disturbances, having a COVID-19 diagnoses, and having mental health symptoms on increased alcohol use. Our findings underscore the importance of providing alcohol use prevention and treatment resources in this unprecedented COVID-19 era. Policymakers, public health professionals, and clinicians have a significant role in curbing the COVID-19-induced substance use epidemic.

Maternal Morbidity and Mortality: Are We Getting to the "Heart" of the Matter?

Cardiovascular disease (CVD), including hypertensive disorders of pregnancy (HDP) and peripartum cardiomyopathy, is a leading cause of pregnancy-related death in the United States. Women who are African American or American Indian/Alaskan Native, have HDP, are medically underserved, are older, or are obese have a major risk for the onset and/or progression of CVD during and after pregnancy. Paradoxically, women with no preexisting chronic conditions or risk factors also experience significant pregnancy-related cardiovascular (CV) complications. The question remains whether substantial physiologic stress on the CV system during pregnancy reflected in hemodynamic, hematological, and metabolic changes uncovers subclinical prepregnancy CVD in these otherwise healthy women. Equally important and similarly understudied is the concept that women's long-term CV health could be detrimentally affected by adverse pregnancy outcomes, such as preeclampsia, gestational hypertension, and diabetes, and preterm birth. Thus, a critical life span perspective in the assessment of women's CV risk factors is needed to help women and health care providers recognize and appreciate not only optimal CV health but also risk factors present before, during, and after pregnancy. In this review article, we highlight new advancements in understanding adverse, pregnancy-related CV conditions and will discuss promising strategies or interventions for their prevention, diagnosis, and treatment.

ImPlementation REsearCh to DEvelop Interventions for People Living with HIV (the PRECluDE consortium): Combatting chronic disease comorbidities in HIV populations through implementation research.

Antiretroviral therapy (ART) prevented premature mortality and improved the quality of life among people living with the human immunodeficiency virus (PLWH), such that now more than half of PLWH in the United States are 50 years of age and older. Increased longevity among PLWH has resulted in a significant rise in chronic, comorbid diseases. However, the implementation of guideline-based interventions for preventing, treating, and managing such age-related, chronic conditions among the HIV population is lacking. The PRECluDE consortium supported by the Center for Translation Research and Implementation Science at the National Heart, Lung, and Blood Institute catalyzes implementation research on proven-effective interventions for co-occurring heart, lung, blood, and sleep diseases and conditions among PLWH. These collaborative research studies use novel implementation frameworks with HIV, mental health, cardiovascular, and pulmonary care to advance comprehensive HIV and chronic disease healthcare in a variety of settings and among diverse populations.

Raf inhibition protects cortical cells against beta-amyloid toxicity.

Alzheimer's disease (AD) is the main cause of dementia in the elderly. The discovery of new targets of therapeutic intervention is fundamental to the development of new drugs against AD pathology. Upregulation of cRaf-1 has been found post-mortem in the brains of AD patients. cRaf-1 is a cytosolic protein kinase that regulates neuronal survival and senescence. In this study, we investigated cRaf-1 in the brains of aged APPswe mice presenting AD-like pathology and whether Raf inhibitors protected cultured cortical cells against amyloid beta toxicity (Abeta). We found a dysregulation of cRaf-1 in the cortex of APPswe mice, which showed a 147% increase in the active form phosphorylated at serine 338 and a 40% decrease in the levels of the inactive form of cRaf-1, phospho-cRaf-1[Ser259]. Furthermore, treatment of primary cortical neurons with the cRaf-1 inhibitors, GW5074 or ZM336372, and the nuclear factor kappa B (NFkappaB) inhibitor SN50, protected cortical neurons against Abeta toxicity. Since Raf stimulates NFkappaB, we studied the effect of Raf inhibition on its activation by studying changes in NFkappaB phosphorylation at serine 276. Our results suggest that Raf inhibition with GW5074 is neuroprotective against Abeta toxicity through a mechanism that involves NFkappaB inhibition.

Continuity of care and hypertension control in a university-based practice.

OBJECTIVES: We describe the relationship between continuity of care and control of hypertension. DESIGN: Retrospective longitudinal cohort study of adults with hypertension. SETTING: University of North Carolina Family Medicine Center. PATIENTS: Hypertensive patients making at least four visits to the Center during a two-year period, 1999-2001. MAIN OUTCOME MEASURES: Longitudinal blood pressure level and dichotomous (<140 systolic and <90 systolic) blood pressure control. Independent variables include continuity of care, race and other demographic information, type of primary provider, and insurance type. RESULTS: Both systolic and diastolic BP fell over the two years (systolic 2.2 mm Hg/year and diastolic 2.8 mm Hg/year). Lower systolic blood pressure was not associated with continuity of care, sex or provider type (faculty vs. resident). Lower diastolic blood pressure had a borderline association with continuity of care (2.2 mm Hg/year, 95% CI -4.7, 0.4). Higher vs. lower continuity of care showed a trend toward better BP control, but the results were not significant (OR 0.84, 95% CI 0.65, 1.09). Lower blood pressures were associated with Caucasian race (vs African American race). CONCLUSIONS: Continuity of care was not related to control of hypertension at our center. The factors related to hypertension control need further research.

A cross-cultural study of physician treatment decisions for demented nursing home patients who develop pneumonia.

PURPOSE: We wanted to explore factors that influence Dutch and US physician treatment decisions when nursing home patients with dementia become acutely ill with pneumonia. METHODS: Using a qualitative semistructured interview study design, we collected data from 12 physicians in the Netherlands and 12 physicians in North Carolina who care for nursing home patients. Our main outcome measures were perceptions of influential factors that determine physician treatment decisions regarding care of demented patients who develop pneumonia. RESULTS: Several themes emerged from the study. First, physicians viewed their patient care roles differently. Dutch physicians assumed active, primary responsibility for treatment decisions, whereas US physicians were more passive and deferential to family preferences, even in cases when they considered families' wishes for care as inappropriate. These family wishes were a second theme. US physicians reported a perceived sense of threat from families as influencing the decision to treat more aggressively, whereas Dutch physicians revealed a predisposition to treat based on what they perceived was in the best interest of the patient. The third theme was the process of decision making whereby Dutch physicians based decisions on an intimate knowledge of the patient, and American physicians reported limited knowledge of their nursing home patients as a result of lack of contact time. CONCLUSION: Physician-perceived care roles regarding treatment decisions are influenced by contextual differences in physician training and health care delivery in the United States and the Netherlands. These results are relevant to the debate about optimal care for patients with poor quality of life who lack decision-making capacity.

Cyclooxygenase-2 inhibition reduces stress-induced affective pathology.

Mood and anxiety disorders are the most prevalent psychiatric conditions and are exacerbated by stress. Recent studies have suggested cyclooxygenase-2 (COX-2) inhibition could represent a novel treatment approach or augmentation strategy for affective disorders including anxiety disorders and major depression. We show that traditional COX-2 inhibitors and a newly developed substrate-selective COX-2 inhibitor (SSCI) reduce a variety of stress-induced behavioral pathologies in mice. We found that these behavioral effects were associated with a dampening of neuronal excitability in the basolateral amygdala (BLA) ex vivo and in vivo, and were mediated by small-conductance calcium-activated potassium (SK) channel and CB1 cannabinoid receptor activation. Taken together, these data provide further support for the potential utility of SSCIs, as well as traditional COX-2 inhibitors, as novel treatment approaches for stress-related psychiatric disorders.

Policies to increase influenza and pneumococcal immunizations in chronically ill and institutionalized settings.

BACKGROUND: The objective of this study was to understand better the status of and ways to improve dissemination of influenza and pneumococcal standing-order vaccination policies to at-risk adults in health care institutions. METHODS: A statewide sample of 5 different types of institutions serving at-risk elderly persons in North Carolina was surveyed. A 45-question telephone survey was administered to infection control nurses or facility directors at 267 (86% response rate) health care facilities involved in direct patient care. RESULTS: A majority of respondents reported that influenza (81%) and pneumococcal (59%) diseases were important to their facility, and 63% stated that the influenza vaccine was very effective versus 47% for pneumococcal. Except nursing homes, few facilities reported adoption of standing-order policies to vaccinate routinely the at-risk adults. Over 70% of respondents stated that their facilities might consider adopting standing-order policies for influenza and pneumococcal disease. A majority of respondents also supported a state law that requires such vaccines for high-risk patients unless contraindicated or the patient refuses. CONCLUSIONS: Respondents across diverse health care institutions appear interested in adopting standing-order policies to increase influenza and pneumococcal vaccination rates and are more likely to do so if provided with appropriate administrative and/or financial support for implementation.
