Cardiac tamponade in venoarterial extracorporeal membrane oxygenation [Case Report]
Cardiac tamponade is a challenging diagnosis in the unstable patient requiring extracorporeal membrane oxygenation. We present a case of cardiac tamponade secondary to hemorrhagic pericardial effusion that developed in the setting of cardiopulmonary resuscitation and venoarterial extracorporeal membrane oxygenation. Specifically, we aim to discuss the pertinent diagnostic challenges in confirming this diagnosis.

Determinants of surgical remission in prolactinomas: a systematic review and meta-analysis
OBJECTIVE:Prolactin secreting tumors respond well to medical management with a small fraction of patients requiring surgery. We conducted a systematic review and meta-analysis to study the determinants of surgical remission in these tumors. METHODS:We searched PubMed to identify eligible studies reporting postoperative remission in patients treated with transsphenoidal surgery for prolactinoma. Primary outcomes included postoperative remission, follow-up remission, and recurrence. Postoperative and follow-up remission were defined as normoprolactinemia at less than and greater than one-year post-operation respectively. Recurrence was defined as hyperprolactinemia after initial normalization of prolactin levels. Odds ratios (OR) were calculated, stratified by radiological size, tumor extension, and tumor invasion, and analyzed using a random-effects model meta-analysis. RESULTS:Thirty-five studies were included. Macroadenomas were associated with lower rates of postoperative remission OR 0.20, 95% confidence interval [CI] 0.16-0.24) and lower rates of remission at follow-up (OR 0.11, 95% CI 0.053-0.22). Postoperative remission was less likely in tumors with extra- or suprasellar extension (OR 0.16, 95% CI 0.06-0.43) and tumors with cavernous sinus invasion (OR 0.03, 95% CI 0.01-0.13). Female gender and absence of preoperative dopamine agonist (DA) treatment were also associated with higher remission rates. Across the included studies, there was considerable heterogeneity in each primary outcome (postoperative remission I2=94%, follow-up remission I2=86%, recurrence I2=68%). CONCLUSIONS:Transsphenoidal surgery for prolactinomas may be particularly effective in small, non-invasive, treatment naive tumors and may provide a viable first-line alternative to dopamine agonist therapy in such patients.

Telemedicine Training in the COVID Era: Revamping a Routine OSCE to Prepare Medicine Residents for Virtual Care
Background/UNASSIGNED:During the rapid onset of the pandemic, clinicians transitioned from traditional outpatient practice to virtual modalities for providing routine care to patient panels. Like training programs nationwide, telemedicine training and assessment had not been systematically incorporated into our residency. In response, a scheduled Internal Medicine (IM) Objective Structured Clinical Examination (OSCE) was adapted to a remote modality to become virtual care-focused learning experience for trainees and to provide valuable feedback to educators. Methods/UNASSIGNED:Standardized Patients (SPs) rated residents on their communication (including information gathering, relationship development and patient education), patient activation and satisfaction, and telemedicine skills. Analyses included a comparison of domain scores for residents who participated in both the 2020 remote and 2019 in-person OSCEs, and a review of written resident comments about the virtual OSCE. Results/UNASSIGNED: = .008). Conclusion/UNASSIGNED:Our reformulated OSCE accomplished 3 goals including; (1) physically distancing residents from SPs per COVID regulations, (2) providing residents with the opportunity to practice critical virtual visit skills, and (3) alerting our educators to curricular improvement areas. Our methods are useful for other institutions and have applications to the larger medical education community.

Baseline brain function in the preadolescents of the ABCD Study
The Adolescent Brain Cognitive Development (ABCD) Study® is a 10-year longitudinal study of children recruited at ages 9 and 10. A battery of neuroimaging tasks are administered biennially to track neurodevelopment and identify individual differences in brain function. This study reports activation patterns from functional MRI (fMRI) tasks completed at baseline, which were designed to measure cognitive impulse control with a stop signal task (SST; N = 5,547), reward anticipation and receipt with a monetary incentive delay (MID) task (N = 6,657) and working memory and emotion reactivity with an emotional N-back (EN-back) task (N = 6,009). Further, we report the spatial reproducibility of activation patterns by assessing between-group vertex/voxelwise correlations of blood oxygen level-dependent (BOLD) activation. Analyses reveal robust brain activations that are consistent with the published literature, vary across fMRI tasks/contrasts and slightly correlate with individual behavioral performance on the tasks. These results establish the preadolescent brain function baseline, guide interpretation of cross-sectional analyses and will enable the investigation of longitudinal changes during adolescent development.

Genome-Wide Heritability Estimates for Family Life Course Complexity
Sequence analysis is an established method used to study the complexity of family life courses. Although individual and societal characteristics have been linked with the complexity of family trajectories, social scientists have neglected the potential role of genetic factors in explaining variation in family transitions and events across the life course. We estimate the genetic contribution to sequence complexity and a wide range of family demographic behaviors using genomic relatedness-based, restricted maximum likelihood models with data from the U.S. Health and Retirement Study. This innovative methodological approach allows us to provide the first estimates of the heritability of composite life course outcomes-that is, sequence complexity. We demonstrate that a number of family demographic indicators (e.g., the age at first birth and first marriage) are heritable and provide evidence that composite metrics can be influenced by genetic factors. For example, our results show that 11% of the total variation in the complexity of differentiated family sequences is attributable to genetic influences. Moreover, we test whether this genetic contribution varies by social environment as indexed by birth cohort over a period of rapid changes in family norms during the twentieth century. Interestingly, we find evidence that the complexity of fertility and differentiated family trajectories decreased across cohorts, but we find no evidence that the heritability of the complexity of partnership trajectories changed across cohorts. Therefore, our results do not substantiate claims that lower normative constraints on family demographic behavior increase the role of genes.

Urine Cell-Free Mitochondrial DNA as a Marker of Weight Loss and Body Composition in Older Adults with HIV
BACKGROUND:Older adults with HIV (OAH) experience more comorbidities and geriatric syndromes than their HIV-negative peers, perhaps due to chronic inflammation. Cell-free mitochondrial DNA (cfmtDNA) released from cells undergoing necrosis-mediated cell death potentially acts as both a mediator and marker of inflammatory dysregulation. We hypothesized that urinary cfmtDNA would be associated with frailty, body composition and fall history in OAH. METHODS:OAH completed frailty testing, a psychosocial survey, body composition assessment, and measurement of urine cfmtDNA and urine albumin:creatinine in this cross-sectional study. Urine cfmtDNA was measured by qPCR and normalized to urinary creatinine. RESULTS:Across 150 participants, the mean age was 61 years (SD 6 years), half identified as Black, one-third were female, and 93% had HIV-1 viral load <200 copies/ml. Two-thirds met criteria for a pre-frail or frail state. Those with unintentional weight loss had higher urine cfmtDNA concentrations (p=0.03). Higher urine cfmtDNA was inversely associated with skeletal muscle index (SMI) (β =-0.19, p<0.01) and fat mass index (FMI) (β =-0.08, p=0.02) in separate multiple linear regression models adjusted for age, sex, and presence of moderate-severe albuminuria. CONCLUSIONS:In this cross-sectional study of OAH, higher levels of urine cfmtDNA were more common in subjects with less robust physical condition, including unintentional weight loss and less height-scaled body mass of fat and muscle. These findings suggest urine cfmtDNA may reflect pathophysiologic aging processes in OAH, predisposing them to geriatric syndromes. Longitudinal investigation of urine cfmtDNA as a biomarker of geriatric syndromes is warranted.

Impact of healthcare services on thyroid cancer incidence among World Trade Center-exposed rescue and recovery workers
BACKGROUND:A recent study of World Trade Center (WTC)-exposed firefighters and emergency medical service workers demonstrated that elevated thyroid cancer incidence may be attributable to frequent medical testing, resulting in the identification of asymptomatic tumors. We expand on that study by comparing the incidence of thyroid cancer among three groups: WTC-exposed rescue/recovery workers enrolled in a New York State (NYS) WTC-medical monitoring and treatment program (MMTP); WTC-exposed rescue/recovery workers not enrolled in an MMTP (non-MMTP); and the NYS population. METHODS:Person-time began on 9/12/2001 or at enrollment in a WTC cohort and ended at death or on 12/31/2015. Cancer data were obtained through linkages with 13 state cancer registries. We used Poisson regression to estimate rate ratios (RRs) and 95% confidence intervals (CIs) for MMTP and non-MMTP participants. NYS rates were used as the reference. To estimate potential changes over time in WTC-associated risk, change points in RRs were estimated using profile likelihood. RESULTS:The thyroid cancer incidence rate among MMTP participants was more than twice that of NYS population rates (RR = 2.31; 95% CI = 2.00-2.68). Non-MMTP participants had a risk similar to NYS (RR = 0.96; 95% CI = 0.72-1.28). We observed no change points in the follow-up period. CONCLUSION/CONCLUSIONS:Our findings support the hypothesis that no-cost screening (a benefit provided by WTC-MMTPs) is associated with elevated identification of thyroid cancer. Given the high survival rate for thyroid cancer, it is important to weigh the costs and benefits of treatment, as many of these cancers were asymptomatic and may have been detected incidentally.
