This study provides data on the feasibility and impact of video-enabled telemedicine use among patients and providers and its impact on urgent and non-urgent health care delivery from one large health system (NYU Langone Health) at the epicenter of the COVID-19 outbreak in the United States. Between March 2nd and April 14th 2020, telemedicine visits increased from 369.1 daily to 866.8 daily (135% increase) in urgent care after the system-wide expansion of virtual health visits in response to COVID-19, and from 94.7 daily to 4209.3 (4345% increase) in non-urgent care post expansion. Of all virtual visits post expansion, 56.2% and 17.6% urgent and non-urgent visits, respectively, were COVID-19-related. Telemedicine usage was highest by patients aged 20-44, particularly for urgent care. The COVID-19 pandemic has driven rapid expansion of telemedicine use for urgent care and non-urgent care visits beyond baseline periods. This reflects an important change in telemedicine that other institutions facing the COVID-19 pandemic should anticipate.

Age of sexual debut is a critical health indicator for young sexual minority men (YSMM), associated with an increased likelihood of HIV acquisition, use of alcohol, tobacco, and other substances, and psychological distress. This study examined the age of same-sex sexual debut for five sexual behaviors in a sample of racially/ethnically and socioeconomically diverse gay-identified YSMM in New York City. The mean age of sexual debut of any behavior was 14.5 years old and 19% of the sample reported sexual debut prior to age 13. Overall, mutual masturbation occurred at the youngest mean age, followed by performed oral, received oral, receptive anal, and insertive anal intercourse. There were significant differences by race/ethnicity and perceived familial socioeconomic status (SES), such that Black and Hispanic/Latino men had earlier ages of debut for performed oral and receptive and insertive anal sex, while upper SES men had later ages of debut for receptive and insertive anal intercourse. These findings are relevant to trends in HIV incidence in the U.S., which are highest among Black and Hispanic/Latino YSMM and may be associated with earlier age of sexual debut. These findings also underscore a need for comprehensive and inclusive sex education at younger ages.

BACKGROUND AND OBJECTIVES:Patients with CKD suffer from frailty and sarcopenia, which is associated with higher morbidity and mortality. Skeletal muscle mitochondria are important for physical function and could be a target to prevent frailty and sarcopenia. In this study, we tested the hypothesis that mitochondrial dysfunction is associated with the severity of CKD. We also evaluated the interaction between mitochondrial function and coexisting comorbidities, such as impaired physical performance, intermuscular adipose tissue infiltration, inflammation, and oxidative stress. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS:P magnetic resonance spectroscopy to obtain the phosphocreatine recovery time constant, a measure of mitochondrial function. We measured physical performance using the 6-minute walk test, intermuscular adipose tissue infiltration with magnetic resonance imaging, and markers of inflammation and oxidative stress in plasma. In skeletal muscle biopsies from a select number of patients on maintenance hemodialysis, we also measured markers of mitochondrial dynamics (fusion and fission). RESULTS:=0.001). We found mitochondrial fragmentation and increased content of dynamin-related protein 1, a marker of mitochondrial fission, in skeletal muscles from patients on maintenance hemodialysis (0.86 [0.48-1.35] arbitrary units (A.U.), median [interquartile range]) compared with controls (0.60 [0.24-0.75] A.U.). CONCLUSIONS:Mitochondrial dysfunction is due to multifactorial etiologies and presents prior to the initiation of maintenance hemodialysis, including in patients with CKD stages 3-5.

Magnetic resonance imaging, histological, and gene analysis approaches in living and nonliving human fetuses and in prematurely born neonates have provided insight into the staged processes of prenatal brain development. Increased understanding of micro- and macroscale brain network development before birth has spurred interest in understanding the relevance of prenatal brain development to common neurological diseases. Questions abound as to the sensitivity of the intrauterine brain to environmental programming, to windows of plasticity, and to the prenatal origin of disorders of childhood that involve disruptions in large-scale network connectivity. Much of the available literature on human prenatal neural development comes from cross-sectional or case studies that are not able to resolve the longitudinal consequences of individual variation in brain development before birth. This review will 1) detail specific methodologies for studying the human prenatal brain, 2) summarize large-scale human prenatal neural network development, integrating findings from across a variety of experimental approaches, 3) explore the plasticity of the early developing brain as well as potential sex differences in prenatal susceptibility, and 4) evaluate opportunities to link specific prenatal brain developmental processes to the forms of aberrant neural connectivity that underlie common neurological disorders of childhood.

This study examined the interrelated and longitudinal impacts of parent-child shared book reading, parenting stress, and early relational health, as measured by both parental warmth and parent sensitivity, from infancy to toddlerhood. To extend findings from previous studies of collateral effects that have been conducted in parenting interventions, we examined parenting behaviors in a broader context to determine whether shared book reading would confer collateral benefits to the parent and parent-child relationship beyond those expected (i.e., language and literacy). It was hypothesized that positive parent-child interactions, such as shared reading, would have positive impacts on parent outcomes such as parenting stress, parental warmth, and sensitivity. The sample consisted of 293 low-income mothers and their children who participated in a randomized controlled trial. Shared book reading, parenting stress, and parental warmth were assessed when children were 6 and 18 months old. We computed a series of cross-lagged structural equation models to examine longitudinal interrelations among these three factors. Results indicated that shared book reading at 6 months was associated with increases in observed and reported parental warmth and observed sensitivity and decreases in parenting stress at 18 months, controlling for baseline risk factors and treatment group status. These findings suggest that early parent-child book reading can have positive collateral impacts on parents' stress and the parent-child relationship over time.

BACKGROUND: Under-treatment of drug and alcohol use in primary care settings has been attributed, in part, to medical providers' negative attitudes toward substance use. As a part of an implementation study of electronic health record-integrated substance use screening in primary care clinics, conducted in the NIDA Clinical Trials Network, we assessed baseline attitudes among medical staff.
METHOD(S): Eligible participants were primary care providers and medical assistants in 4 urban academic primary care clinics. Prior to implementation of a substance use screening program, participants completed the Substance Abuse Attitudes Survey (SAAS), a validated 50-item self-administered survey that measures attitudes to substance use in 5 domains: permissiveness, non-moralism, nonstereotyping, treatment intervention, and treatment optimism. Participants were asked to rate their level of agreement with each item on a five-point Likert scale.
RESULT(S): In total, 131/191 (69% response rate) eligible staff completed the survey. Participants had mean age 42; 76% were female; 11% Hispanic/Latino, 6% Black, 25% Asian. The majority of the sample was physicians (78%), while 11% were nurse practitioners, and 11% were medical assistants. Participants had an overall average of 13.2 years in practice. Approximately onethird reported moderate to high satisfaction treating patients with drug problems (35.1%) and alcohol problems (33.6%). The proportion of participants having positive attitudes in each of the following domains were: non-moralism (64.1%); non-stereotyping (55.7%); treatment intervention (47.3%); treatment optimism (48.9%); and permissiveness (44.3%). Negative attitudes toward permissiveness reflect responses to items addressing health effects of substance use, especially among teens.
CONCLUSION(S): While most primary care staff did not endorse moralistic or stereotyping statements about alcohol and drug use, attitudes toward addiction treatment were mixed, with less than half endorsing positive attitudes toward treatment effectiveness. These results suggest a need to improve attitudes, particularly toward addiction treatment. This could be accomplished through education and increased exposure to effective interventions that can be delivered by primary care providers, including officebased treatment for alcohol and opioid use disorder

BACKGROUND:Mammography is limited when analyzing dense breasts for 2 reasons: (1) breast density masks underlying cancers and (2) breast density is an independent risk factor for cancer. We undertook this study to assess whether there is a racial/ethnic difference in supplemental image ordering for women with dense breasts. METHODS:We conducted a retrospective, observational cohort study of women aged 50-75 from an academic medical center who had completed a screening mammogram between 2014 and 2016 that was read as BI-RADS 1 with heterogeneously or extremely dense breasts or BI-RADS 2 with extremely dense breasts. Data were abstracted on type, timing and frequency of supplemental imaging tests ordered within two years of an initial screening mammogram. Patient characteristics (age, race/ethnicity, insurance, and comorbidities) were also abstracted. We used bivariate and multivariate logistic regression to assess for differences in supplemental imaging ordered by race/ethnicity. RESULTS:Three hundred twenty-six women met inclusion criteria. Mean age was 58 years: 25% were non-Hispanic white, 30% were non-Hispanic black, 27% were Hispanic, 6% were Asian and 14% unknown. Seventy-nine (24%) women were ordered a supplemental breast ultrasound after the initial screening mammogram. Non-Hispanic black and Hispanic women were less likely to have supplemental imaging ordered compared to non-Hispanic white women (15% and 10%, respectively, vs. 45%, p < 0.0001). After controlling for patient age, ordering physician specialty, insurance, BI-RADS score, breast density, and family history of breast cancer, non-Hispanic black and Hispanic women remained less likely to be ordered supplemental imaging (OR 0.38 [95% CI 0.17-0.85] and OR 0.24 [95% CI 0.10-0.61], respectively, p < 0.0001). CONCLUSION/CONCLUSIONS:Minority women with dense breasts are less likely to be ordered supplemental breast imaging. Further research should investigate physician and patient behaviors to determine barriers in supplemental imaging. Understanding these differences may help reduce disparities in breast cancer care and mortality.

Sixteen million caregivers currently provide care to more than 5 million persons living with dementia (PLWD) in the United States. Although this population is growing and highly complex, evidence-based management remains poorly integrated within healthcare systems. Therefore, the National Institute on Aging IMPACT Collaboratory was formed to build the nation's ability to conduct embedded pragmatic clinical trials (ePCTs) for PLWD and their caregivers. The pilot core of the IMPACT Collaboratory seeks to provide funds for upward of 40 pilots for ePCTs to accelerate the testing of nonpharmacologic interventions with the goal that these pilots lead to full-scale ePCTs and eventually the embedding of evidence-based care into healthcare systems. The first two challenges for the pilot core in building the pilot study program were (1) to develop a transparent, ethical, and open nationwide process for soliciting, reviewing, and selecting pilot studies; and (2) to begin the process of describing the necessary components of a pilot study for an ePCT. During our initial funding cycle, we received 35 letters of intent, of which 17 were accepted for a full proposal and 14 were submitted. From this process we learned that investigators lack knowledge in ePCTs, many interventions lack readiness for an ePCT pilot study, and many proposed studies lack key pragmatic design elements. We therefore have set three key criteria that future pilot studies must meet at a minimum to be considered viable. We additionally discuss key design decisions investigators should consider in designing a pilot study for an ePCT. J Am Geriatr Soc 68:S14-S20, 2020.
