RESUMEN
Objective: The COVID-19 pandemic served as an impetus for the rapid expansion of telehealth. In this study, we examined the experience of rapid transition to telemental health (TMH) within The Family Health Centers at NYU Langone, a large, urban, Federally Qualified Health Center, in the 3 months after the onset of the COVID-19 pandemic. Methods: We administered surveys to clinicians and patients who utilized TMH between March 16, 2020 and July 16, 2020. Patients were sent a web-based survey via email or received a phone survey (for those without email) with four languages choices: English, Spanish, Traditional Chinese, or Simplified Chinese. Results: The majority (79%) of clinicians (n = 83) rated the experience of TMH as "excellent" or "good," and felt that they could establish and maintain the patient relationship through TMH. Four thousand seven hundred seventy-two survey invitations were sent out to patients, and 654 (13.7%) responded. Ninety percent reported that they were satisfied with the service they received and rated TMH as better or the same as in-person care (81.6%) with a high mean satisfaction score (4.5 out of 5). Patients were more likely to rate TMH as better or the same as in-person care relative to the clinicians. Conclusions: These results are consistent with several recent studies that have explored patient satisfaction with TMH during the COVID-19 pandemic and demonstrate that both clinicians and patients experienced a high degree of satisfaction with mental health care delivered virtually compared with face-to-face encounters.

Suicide is a critical public health problem. Over the past decade, suicide rates have increased among Black and Latinx adults in the U.S. Though depression is the most prevalent psychiatric contributor to suicide risk, Black and Latinx Americans uniquely experience distress and stress (e.g., structural adversity) that can independently operate to worsen suicide risk. This makes it important to investigate non-clinical, subjective assessment of mental health as a predictor of suicide ideation. We also investigate whether social support can buffer the deleterious impact of poor mental health on suicide ideation.We analyzed data from 1,503 Black and Latinx participants of the Washington Heights Community Survey, a 2015 survey of residents of a NYC neighborhood. Multivariable logistic regression was conducted to examine the effect of subjectively experienced problems with anxiety and depression on suicide ideation independent of depression diagnosis, and the role of social support as a moderator.Estimated prevalence of past two-week suicide ideation was 5.8%. Regression estimates showed significantly increased odds of suicide ideation among participants reporting moderate (OR = 8.54,95% CI = 2.44-29.93) and severe (OR = 16.84,95% CI = 2.88-98.46) versus no problems with anxiety and depression, after adjustment for depression diagnosis. Informational support, i.e., having someone to provide good advice in a crisis, reduced the negative impact of moderate levels of anxiety and depression problems on suicide ideation.Findings suggest that among Black and Latinx Americans, subjective feelings of anxiety and depression account for a significant portion of the suicide ideation risk related to poor mental health. Further, social support, particularly informational support, may provide protection against suicide ideation.

Background: Data on Internet utilization is needed, particularly during a time when in-person services are limited or only available virtually. The purpose of this study was to identify characteristics of Internet use among persons who use drugs and assess adoption of an interactive, risk reduction informational website - WebHealth4Us. Methods: Participant recruitment occurred in pharmacies participating in the New York State pharmacy syringe access program (n = 209). ACASI surveys were conducted on-site to ascertain Internet use and related sociodemographics and risk behaviors. Internet users (use ≥ once/month) were shown a website WebHealth4Us highlighting social services and risk reduction information on four topic areas: mental health, HIV, HCV, and other STI; users could also sign-up for weekly text messages for any topic area. Follow-up ACASI occurred at four weeks to assess user experiences and website adoption. Results: Study sample (n = 196) was mostly male (60%), average age 46, black/Latinx (76%), had a history of incarceration (79%), and reported past/current injection (53%) or non-injection (51%) drug use. Internet use was high (79%), accessed >4 times/week (60%) most commonly for: housing (61%), health issues (54%), and drug treatment (45%). Over one-third accessed WebHealth4Us during follow-up, and 35% of those opted for weekly text messages (mental health most common topic selected). After adjustment, younger age (AOR = 0.96) and alcohol use (AOR = 2.26) predicted WebHealth4Us access. Conclusion: Internet use was high with considerable WebHealth4Us access, and specifically for mental health needs. Web-based interventions warrant large-scale investigation in high-risk communities, prioritizing social determinants and behavioral health.

Biomedical HIV prevention uptake has not taken hold among Black and Latinx populations who use street-marketed drugs. A pilot intervention providing a PEP informational video and direct pharmacy access to a PEP starter dose was conducted among this population. Four study pharmacies were selected to help facilitate syringe customer recruitment (2012-2016). Baseline, post-video, and 3-month ACASI captured demographic, risk behavior, and psychosocial factors associated with PEP willingness, and willingness to access PEP in a pharmacy. A non-experimental study design revealed baseline PEP willingness to be associated with PEP awareness, health insurance, being female, and having a high-risk partner (n = 454). Three-month PEP willingness was associated with lower HIV stigma (APR = 0.95). Using a pre-post approach, PEP knowledge (p < 0.001) and willingness (p < 0.001) increased overtime; however, only three participants requested PEP during the study. In-depth interviews (n = 15) identified lack of a deeper understanding of PEP, and contextualized perceptions of HIV risk as PEP access barriers. Pharmacy PEP access shows promise but further research on perceived risk and HIV stigma is warranted.

We examined the association between sexually transmitted disease (STD) and depressive symptoms. Our analysis utilized the 2015 cross-sectional Washington Heights Community Survey. Multivariable binary logistic regression analysis was used to examine the primary association between having a history of STD and patient health questionnaire-9 (PHQ-9) score while adjusting for potential confounders. Then in separate models, we adjusted for the interaction of social factors with PHQ-9 score to test for modification effect on the primary association. In this low-income neighborhood, STD history was not significantly associated with PHQ-9 score in the overall logistic regression model for the primary association. However, in interaction models, STD and depressive symptoms were associated in sub-groups defined by social factors, namely being Hispanic [odds ratio (OR) 1.08; 95% confidence interval (CI) 1.02-1.15], foreign-born (OR 1.08; 95% CI 1.02-1.15), and having low to moderate social support (OR 1.09; 95% CI 1.02-1.15). Our results demonstrate a need for targeted interventions to be applied to vulnerable subgroups identified.

In the United States, suicide deaths have disproportionately increased among Black and Hispanic youth over the past 2 decades.1 Despite the critical need for more culturally responsive suicide prevention strategies, there has been only sparse research into unique risk factors commonly experienced among ethnoracially minoritized youth, such as racism-related experiences. Experiences of racial and ethnic discrimination (ie, a behavioral manifestation of racism via unfair treatment predicated on an individual's racial and/or ethnic group affiliation) have been associated with higher rates of suicidal thoughts and behaviors (STBs) in Black and Hispanic adolescents.2,3 This research has largely focused on individual-level racism (ie, interpersonal exchanges) assessed via subjective self-report surveys. Thus, less is known about the impact of structural racism, which is enacted at the system level.

BACKGROUND: Black women and Latinas in their thirties continue to be at risk for HIV transmission via heterosexual intercourse. METHODS: Informed by the Theory of Gender and Power, this study investigated a longitudinal path model linking experiences of ethnic-racial discrimination in late adolescence to sexual risk behaviors in adulthood among 492 Black women and Latinas. We also tested whether ethnic-racial identity exploration served as a resilience asset protecting women against the psychological impact of ethnic-racial discrimination. Survey data from female participants in the Harlem Longitudinal Development Study, which has followed a cohort of New York City Black and Latinx youth since 1990, were analyzed. Data for this analysis were collected at four time points when participants were on average 19, 24, 29, and 32 years of age. Structural equation modeling was used to examine a hypothesized pathway from earlier ethnic-racial discrimination to later sexual risk behaviors and the protective role of ethnic-racial identity exploration. RESULTS: Results confirmed that ethnic-racial discrimination in late adolescence was linked with sexual risk behaviors in the early thirties via increased levels of affective distress in emerging adulthood, experiences of victimization in young adulthood, and substance use in the early thirties among women low in ethnic-racial identity exploration. We also found that ethnic-racial identity served as a resilience asset, as the association between discrimination in late adolescence and affective distress in emerging adulthood was not significant among women with higher levels of ethnic-racial identity exploration. CONCLUSIONS: The results provide important preliminary evidence that ethnic-racial identity exploration may serve as a resilience asset among Black women and Latinas confronting racial discrimination. Further, we suggest that ethnic-racial identity exploration may constitute an important facet of critical consciousness.

Importance: Individuals with serious mental illness are at increased risk of severe COVID-19 infection. Several psychotropic medications have been identified as potential therapeutic agents to prevent or treat COVID-19 but have not been systematically examined in this population. Objective: To evaluate the associations between the use of psychotropic medications and the risk of COVID-19 infection among adults with serious mental illness receiving long-term inpatient psychiatric treatment. Design, Setting, and Participants: This retrospective cohort study assessed adults with serious mental illness hospitalized in a statewide psychiatric hospital system in New York between March 8 and July 1, 2020. The final date of follow-up was December 1, 2020. The study included 1958 consecutive adult inpatients with serious mental illness (affective or nonaffective psychoses) who received testing for SARS-CoV-2 by reverse transcriptase-polymerase chain reaction or antinucleocapsid antibodies and were continuously hospitalized from March 8 until medical discharge or July 1, 2020. Exposures: Psychotropic medications prescribed prior to COVID-19 testing. Main Outcomes and Measures: COVID-19 infection was the primary outcome, defined by a positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction or antibody test result. The secondary outcome was COVID-19-related death among patients with laboratory-confirmed infection. Results: Of the 2087 adult inpatients with serious mental illness continuously hospitalized during the study period, 1958 (93.8%) underwent testing and were included in the study; 1442 (73.6%) were men, and the mean (SD) age was 51.4 (14.3) years. A total of 969 patients (49.5%) had laboratory-confirmed COVID-19 infection that occurred while they were hospitalized; of those, 38 (3.9%) died. The use of second-generation antipsychotic medications, as a class, was associated with decreased odds of infection (odds ratio [OR], 0.62; 95% CI, 0.45-0.86), whereas the use of mood stabilizers was associated with increased odds of infection (OR, 1.23; 95% CI, 1.03-1.47). In a multivariable model of individual medications, the use of paliperidone was associated with decreased odds of infection (OR, 0.59; 95% CI, 0.41-0.84), and the use of valproic acid was associated with increased odds of infection (OR, 1.39; 95% CI, 1.10-1.76). Clozapine use was associated with reduced odds of mortality in unadjusted analyses (unadjusted OR, 0.25; 95% CI, 0.10-0.62; fully adjusted OR, 0.43; 95% CI, 0.17-1.12). Conclusions and Relevance: In this cohort study of adults hospitalized with serious mental illness, the use of second-generation antipsychotic medications was associated with decreased risk of COVID-19 infection, whereas the use of valproic acid was associated with increased risk. Further research is needed to assess the mechanisms that underlie these findings.

OBJECTIVES: We examined whether periodontal treatment or other dental care is associated with adverse birth outcomes within a medical and dental insurance database. METHODS: In a retrospective cohort study, we examined the records of 23,441 women enrolled in a national insurance plan who delivered live births from singleton pregnancies in the United States between January 1, 2003, and September 30, 2006, for adverse birth outcomes on the basis of dental treatment received. We compared rates of low birthweight and preterm birth among 5 groups, specifying the relative timing and type of dental treatment received. We used logistic regression analysis to compare outcome rates across treatment groups while adjusting for duration of continuous dental coverage, maternal age, pregnancy complications, neighborhood-level income, and race/ethnicity. RESULTS: Analyses showed that women who received preventive dental care had better birth outcomes than did those who received no treatment (P < .001). We observed no evidence of increased odds of adverse birth outcomes from dental or periodontal treatment. CONCLUSIONS: For women with medical and dental insurance, preventive care is associated with a lower incidence of adverse birth outcomes.

INTRODUCTION: The purpose of this study is to assess community pharmacists' attitudes and experiences related to naloxone dispensation and counseling in non-urban areas in New York State to better understand individual and structural factors that influence pharmacy provision of naloxone. MATERIALS AND METHODS: The study conducted interviewer-administered semistructured surveys among community pharmacists in retail, independent, and supermarket pharmacies between October 2019 and December 2019. The 29-item survey ascertained pharmacists' demographic and practice characteristics; experiences and beliefs related to naloxone dispensation; and attitudes toward expansion of pharmacy services to include on-site public health services for persons who use opioids. The study used Chi square tests to determine associations between each characteristic and self-reported naloxone dispensation (any vs. none). RESULTS: A total of 60 of the 80 community pharmacists that the study team had approached agreed to participate. A majority were supportive of expanding pharmacy-based access to vaccinations (93.3%), on-site HIV testing, or referrals (75% and 96.7%, respectively), providing information on safe syringe use (93.3%) and disposal (98.3%), and referrals to medical/social services (88.3%), specifically substance use treatment (90%). A majority of pharmacist respondents denied negative impacts on business with over half reporting active naloxone dispensation (58.3%). Pharmacists dispensing naloxone were more likely to be multilingual (p < 0.03), and to specifically support on-site HIV testing (p < 0.02) than those who were not dispensing naloxone. DISCUSSION: Community pharmacists were highly favorable of naloxone dispensation in rural and small metro area pharmacies in NY, and those fluent in additional language(s) and supportive of on-site HIV testing were associated with active naloxone dispensation. While active naloxone dispensation was low, pharmacists appear supportive of a "frontline public health provider" model, which could facilitate naloxone uptake and warrants large-scale investigation. CONCLUSION: Rural and small metro area pharmacists are generally favorable of naloxone dispensation.

In animal models that mimic human third-trimester fetal development, ethanol causes substantial cellular apoptosis in the brain, but for most brain structures, the extent of permanent neuron loss that persists into adulthood is unknown. We injected ethanol into C57BL/6J mouse pups at postnatal day 7 (P7) to model human late-gestation ethanol toxicity, and then used stereological methods to investigate adult cell numbers in several subcortical neurotransmitter systems that project extensively in the forebrain to regulate arousal states. Ethanol treatment caused especially large reductions (34-42%) in the cholinergic cells of the basal forebrain, including cholinergic cells in the medial septal/vertical diagonal band nuclei (Ch1/Ch2) and in the horizontal diagonal band/substantia innominata/nucleus basalis nuclei (Ch3/Ch4). Cell loss was also present in non-cholinergic basal forebrain cells, as demonstrated by 34% reduction of parvalbumin-immunolabeled GABA cells and 25% reduction of total Nissl-stained neurons in the Ch1/Ch2 region. In contrast, cholinergic cells in the striatum were reduced only 12% by ethanol, and those of the brainstem pedunculopontine/lateral dorsal tegmental nuclei (Ch5/Ch6) were not significantly reduced. Similarly, ethanol did not significantly reduce dopamine cells of the ventral tegmental area/substantia nigra or serotonin cells in the dorsal raphe nucleus. Orexin (hypocretin) cells in the hypothalamus showed a modest reduction (14%). Our findings indicate that the basal forebrain is especially vulnerable to alcohol exposure in the late gestational period. Reduction of cholinergic and GABAergic projection neurons from the basal forebrain that regulate forebrain arousal may contribute to the behavioral and cognitive deficits associated with neonatal ethanol exposure.

OBJECTIVE: To examine the effect of long-term violent victimization from late adolescence to the mid-30s on posttraumatic stress disorder (PTSD) and comorbid psychiatric disorders in adulthood among urban African Americans and Puerto Ricans. METHOD: Data were collected from a large urban community sample (N = 674) at 4 time points associated with mean ages of 19, 24, 29, and 36 years. Trajectories of violent victimization were extracted using growth mixture modeling and used to predict psychiatric disorders and comorbidities in adulthood. RESULTS: The sample was 52.8% African American and 47.2% Puerto Rican, with 60% females. Three trajectory groups of violent victimization were identified: high, intermediate, and low. Over half of the sample reported relatively high- and intermediate-level violent victimization experiences from adolescence to adulthood. Group comparisons showed that participants belonging to the relatively high-victimization group had greater odds of having PTSD, major depressive episode (MDE), and substance use disorder (SUD) separately, as well as comorbid PTSD-SUD and PTSD-MDE, compared with those classified as having relatively low levels of victimization. Having intermediate-level victimization experiences, compared with low-level victimization experiences, over time was associated with higher odds of PTSD and MDE separately and comorbid PTSD-MDE. CONCLUSIONS: Long-term exposure to relatively high levels of violent victimization during emerging and young adulthood is associated with PTSD and comorbid psychiatric disorders in the 30s. Social, structural, and interpersonal factors underlying the differential patterns of violent victimization in urban African American and LatinX youth need to be identified to adequately inform prevention efforts.

OBJECTIVES: Material well-being, beliefs, and emotional states are believed to influence one's health and longevity. In this paper, we explore racial differences in self-rated health, happiness, trust in others, feeling that society is fair, believing in God, frequency of sexual intercourse, educational attainment, and percent in poverty and their association with mortality. STUDY DESIGNS: Age-period-cohort (APC) study. METHODS: Using data from the 1978-2014 General Social Survey-National Death Index (GSS-NDI), we conducted APC analyses using generalized linear models to quantify the temporal trends of racial differences in our selected measures of well-being, beliefs, and emotional states. We then conducted APC survival analysis using mixed-effects Cox proportional hazard models to quantify the temporal trends of racial differences in survival after removing the effects of racial differences in our selected measures. RESULTS: For whites, the decline in happiness was steeper than for blacks despite an increase in high school graduation rates among whites relative to blacks over the entire period, 1978-2010. Self-rated health increased in whites relative to blacks from 1978 through 1989 but underwent a relative decline thereafter. After adjusting for age, sex, period effects, and birth cohort effects, whites, overall, had higher rates of self-rated health (odds ratio [OR] = 1.88; 95% confidence interval [CI] = 1.63, 2.16), happiness (OR = 2.05; 1.77, 2.36), and high school graduation (OR = 2.88; 2.34, 3.53) compared with blacks. Self-rated health, happiness, and high school graduation also mediated racial differences in survival over time. CONCLUSIONS: We showed that some racial differences in survival could be partly mitigated by eliminating racial differences in health, happiness, and educational attainment. Future research is needed to analyze longitudinal clusters and identify causal mechanisms by which social, behavioral, and economic interventions can reduce survival differences.

BACKGROUND: The Fatality Analysis Reporting System (FARS) provides important data for studying the role of marijuana in motor vehicle crashes. However, marijuana testing data are available for only 34% of drivers in the FARS, which represents a major barrier in the use of the data. METHODS: We developed a multiple imputation (MI) procedure for estimating marijuana positivity among drivers with missing marijuana test results, using a Bayesian multilevel model that allows a nonlinear association with blood alcohol concentrations (BACs), accounts for correlations among drivers in the same states, and includes both individual-level and state-level covariates. We generated 10 imputations for the missing marijuana-testing data using Markov chain Monte Carlo simulations and estimated positivity rates of marijuana in the nation and each state. RESULTS: Drivers who were at older age, female, using seatbelt at the time of crash, having valid license, or operating median/heavy trucks were less likely to test positive for marijuana. There was a reverse U-shaped association between BACs and positivity of marijuana, with lower positivity when BACs < 0.01 g/dL or ≥0.15 g/dL. The MI data estimated a lower positivity rate of marijuana in the nation and each of the state than the observed data, with a national positivity rate of 11.7% (95% CI: 11.1, 12.4) versus 14.8% using the observed data in 2013. CONCLUSIONS: Our MI procedure appears to be a valid approach to addressing missing marijuana data in the FARS and may help strengthen the capacity of the FARS for monitoring the epidemic of drugged driving and understanding the role of marijuana in fatal motor vehicle crashes in the United States.

BACKGROUND: Driving under the influence of marijuana is a serious traffic safety concern in the United States. Delta 9-tetrahydrocannabinol (THC) is the main active compound in marijuana. Although blood THC testing is a more accurate measure of THC-induced impairment, measuring THC in oral fluid is a less intrusive and less costly method of testing. METHODS: We examined whether the oral fluid THC test can be used as a valid alternative to the blood THC test using a sensitivity and specificity analysis and a logistic regression, and estimate the quantitative relationship between oral fluid THC concentration and blood THC concentration using a correlation analysis and a linear regression on the log-transformed THC concentrations. We used data from 4596 drivers who participated in the 2013 National Roadside Survey of Alcohol and Drug Use by Drivers and for whom THC testing results from both oral fluid and whole blood samples were available. RESULTS: Overall, 8.9% and 9.4% of the participants tested positive for THC in oral fluid and whole blood samples, respectively. Using blood test as the reference criterion, oral fluid test for THC positivity showed a sensitivity of 79.4% (95% CI: 75.2%, 83.1%) and a specificity of 98.3% (95% CI: 97.9%, 98.7%). The log-transformed oral fluid THC concentration accounted for about 29% of the variation in the log-transformed blood THC concentration. That is, there is still 71% of the variation in the log-transformed blood THC concentration unexplained by the log-transformed oral fluid THC concentration. Back-transforming to the original scale, we estimated that each 10% increase in the oral fluid THC concentration was associated with a 2.4% (95% CI: 2.1%, 2.8%) increase in the blood THC concentration. CONCLUSIONS: The oral fluid test is a highly valid method for detecting the presence of THC in the blood but cannot be used to accurately measure the blood THC concentration.
RESUMEN
Many large provider networks are investing heavily in preventing disease within the communities that they serve. We explore the potential benefits and challenges associated with tackling depression at the community level using a unique dataset designed for one such provider network. The economic costs of having depression (increased medical care use, lower quality of life, and decreased workplace productivity) are among the highest of any disease. Depression often goes undiagnosed, yet many believe that depression can be treated or prevented altogether. We explore the prevalence, distribution, economic burden, and the psychosocial and economic factors associated with undiagnosed depression in a lower-income neighborhood in northern Manhattan. Even using state-of-the art data to "diagnose" the risk factors within a community, it can be challenging for provider networks to act against such risk factors.
