Abstract
Pulse-like carbon dioxide release to the atmosphere on centennial time scales has only been identified for the most recent glacial and deglacial periods and is thought to be absent during warmer climate conditions. Here, we present a high-resolution carbon dioxide record from 330,000 to 450,000 years before present, revealing pronounced carbon dioxide jumps (CDJ) under cold and warm climate conditions. CDJ come in two varieties that we attribute to invigoration or weakening of the Atlantic meridional overturning circulation (AMOC) and associated northward and southward shifts of the intertropical convergence zone, respectively. We find that CDJ are pervasive features of the carbon cycle that can occur during interglacial climate conditions if land ice masses are sufficiently extended to be able to disturb the AMOC by freshwater input.

Maturation of the Human Cerebral Cortex During Adolescence: Myelin or Dendritic Arbor? Cereb Cortex 2020; 29:3351-3362.

Abstract
Previous in vivo studies revealed robust age-related variations in structural properties of the human cerebral cortex during adolescence. Neurobiology underlying these maturational phenomena is largely unknown. Here we employ a virtual-histology approach to gain insights into processes associated with inter-regional variations in cortical microstructure and its maturation, as indexed by magnetization transfer ratio (MTR). Inter-regional variations in MTR correlate with inter-regional variations in expression of genes specific to pyramidal cells (CA1) and ependymal cells; enrichment analyses indicate involvement of these genes in dendritic growth. On the other hand, inter-regional variations in the change of MTR during adolescence correlate with inter-regional profiles of oligodendrocyte-specific gene expression. Complemented by a quantitative hypothetical model of the contribution of surfaces associated with dendritic arbor (1631 m2) and myelin (48 m2), these findings suggest that MTR signals are driven mainly by macromolecules associated with dendritic arbor while maturational changes in the MTR signal are associated with myelination.

Abstract
Bilateral axillary Paget's disease in men is a rare occurrence with limited reports on its diagnosis, treatment, and prognosis. Here, we report the case of a 55-year-old Korean male, who presented with a palpable mass and eczematous skin lesion on the left axilla. An incisional biopsy and histopathologic examination indicated invasive ductal carcinoma with Paget's disease arising in the accessory breast. Magnetic resonance imaging and positron emission tomography revealed no malignancy in the normal breast and other organs. The patient was subjected to a wide excision, wherein the left axillary lymph node was dissected, followed by the administration of adjuvant chemotherapy and radiation therapy. After 17 months of disease-free survival, the patient was diagnosed with Paget's disease of the contralateral accessory breast. He underwent wide excision surgery along with radiation therapy. To the best of our knowledge, this is the first report of bilateral extramammary Paget's disease in a male.

Abstract
Abstract
Introduction
Short sleep duration is associated with the risk of various chronic diseases, and it has been hypothesized to influence health behaviors and environmental exposure such as green space and noise. However, little studies have explored this relationship, especially with the consideration of the integrated environment information. The purpose of this study is to examine the influence of environmental exposure and individuals’ health behavior on sleep duration.
Methods
We examined aggregate national-level datasets regarding health information, noise, and green space. Sleep, health behavior, and socio-demographic variables were derived from 500 cities data, and the unit of analysis was the prevalence of each variable in the census tract. The insufficient sleep was calculated by the percentage of the population who had less than 7 hours of sleep in the census block. Spatial analysis was performed for green space and noise measurement; both values were calculated within the community activity space, which is a combined area with the census urban area and census place to examine the potential activity space. Multiple linear regression analysis was performed to model the relationship.
Results
The final sample was 29,610 census tracts from 497 cities, and the average median age of each census tract was 36.02±7.085. 36.64% of insufficient sleep was reported from the entire sample. The model (R2=0.804) indicate that green space (β=-.053, p<.001) and natural noise (β=-.029, p<.001) has negatively associated with insufficient sleep; while, smoker (β=.374, p<.001), binge drinker (β=.105, p<.001), no leisure physical activity time (β=.111, p<.001), and artificial noise (β=.034, p<.001) has positive association with insufficient sleep.
Conclusion
The results indicate that a better environment source in the community mitigates the insufficient sleep population as well as individual health behavior. Further studies are needed, however, to fully disentangle the association between sleep duration and sleep quality associated with other environmental exposure.

Abstract
Abstract
Introduction
Emerging empirical evidence suggests green space exposure is protective against insufficient sleep. Limited studies exist, however, exploring the relationship between greenspace exposure and sleep among low income populations in the United States.
Methods
Using a sample of Supplemental Nutrition Assistance Program (SNAP) participants (n=104) recruited from Champaign County, Illinois, we examined the relationship between self-reported sleep duration and exposure to green space. Sleep duration was determined using the question, “On average, how many hours did you sleep each night during the past 4 weeks?” Green space exposure was determined using satellite imagery from the National Aeronautic Space Administration (NASA) normalized difference vegetation index (NDVI). An NDVI score was assigned to each participant based on residential geo-referenced data. Multiple linear regression was performed in SPSS to explore the relationship between self-reported sleep duration and green space.
Results
Higher number of hours of sleep within a 24-hour period was positively associated with higher scores for greenspace exposure (β=0.091, P=0.02), controlling for age, gender, smoking status, education, alcohol consumption, and sleep quality. Sleep duration was negatively associated with age (β=-0.03, P=0.007), but positively associated with sleep quality (β=0.856, P=0.008).
Conclusion
In a sample of SNAP participants, exposure to green space was associated with more hours of sleep per night. Additional studies with larger, and more geographically diverse samples of low income adults are needed to determine whether this relationship is robust.

Abstract
Abstract
Background
Paradoxical beneficial effects of obesity on all-cause and cardiovascular mortality have been reported in multiple cohort studies based on patients with cardiovascular disease as well as general populations. However, the association between the presence of obesity at baseline and the better survival rates could not be directly interpreted into the beneficial effect of gain in obesity or fatness on the mortality, which makes it difficult to provide any recommendation for the management of obesity. Therefore, we investigated the influence of the changes in body fat on all-cause and cardiovascular mortality in a general population.
Methods
A population-based cohort study has been conducted for 12 years (from 2001 to 2012). A total of 5,259 subjects in whom body compositions using a bio-impedance method were measured at least 2 times during the observational period were included. The causes of death was identified from the nation-wide database in KOSTAT. I20-I82 and R99 in the International Classification of Disease-10 codes were defined as a cardiovascular death. The subjects were evenly divided into 3 groups by the percentages of the changes in body fat (Δ%BF; decreased [Δ%BF <0.0%] vs. increased [Δ%BF 0.0–13.7%] vs. highly increased [Δ%BF ≥13.7%]). Inverse probability of treatment weighting was applied to balance the covariate differences among the groups.
Results
The age was 51.2±8.5 years and 51.6% was male. Median observation duration was 163 (the interquartile range: 157–168) months. The all-cause death and cardiovascular death occurred most frequently in the decreased Δ%BF group and least frequent in the highly increased Δ%BF group in both unweighted and weighted cohort. Multivariate Cox proportional hazard models showed that the risk of all-cause death was lower in the increased and highly increased Δ%BF groups (hazard ratio [HR] 0.61 [0.47–0.80] and 0.24 [0.17–0.34], respectively) and the risk of cardiovascular death was lower in the highly increased Δ%BF group (HR 0.20 [0.08–0.48]), compared to those in the decreased Δ%BF group after adjustment for all covariates including physical activities and the changes in muscle mass. The risk of all-cause death and cardiovascular death linearly decreased with increasing Δ%BF (HR 0.72 [0.67–0.77] and 0.70 [0.60–0.82], respectively).
Conclusion
The increase in body fat is associated with a lower risk of all-cause death and cardiovascular death in a middle-age general population, independently with physical activities and the changes in muscle mass.

Abstract
Abstract
Purpose
Patients with diabetes mellitus have an elevated risk of atrial fibrillation (AF). However, whether insulin resistance may elevate risk of AF incidence in non-diabetic is inconsistent. The aim of our study was to verify the association between insulin resistance and incidence of AF in non-diabetics.
Methods
We evaluated population-based cohorts embedded in the Korean Genome Epidemiology Study. Insulin resistance was expressed as Homeostasis Model Assessment for Insulin resistance (HOMA-IR). Baseline data including HOMA-IR and electrocardiography (ECG) were obtained at 2001. Subsequent biennial ECG was performed for identification of AF until 2016.
Results
Among the 8220 participants (46.8% male; median age 49 years), 25 participants had AF (0.3%) at baseline and 101 participants developed AF (1.2%) during follow up of 12 years. In multivariate Cox regression analysis, high HOMA-IR (≥1.4) was significantly associated with incident AF compared with low HOMA-IR (<1.40) (adjusted hazard ratio [HR] 1.9, 95% confidence interval [CI] 1.3–3.0). In subgroup analysis, these association was consistent regardless of obesity (BMI<25; adjust HR 1.8, 95% CI 1.1–3.0, BMI≥25; adjust HR 2.3, 95% CI 1.3–4.0)
Subgroup analysis
Conclusion
Based on prospective cohort study, insulin resistance (HOMA-IR) was associated with AF independently of obesity in non-diabetics.

Abstract
BACKGROUND Primary breast sarcoma (PBS) is rare, comprising approximately 1% of breast malignancies. Rhabdomyosarcoma (RMS) accounts for an extremely small proportion of PBSs, often leading to delayed histologic confirmation. METHODS Upon reviewing Asan Medical Center's pathology database between 2000 and 2018, 41 PBS cases were retrieved, including three cases of primary RMS of the breast. Their clinicopathological features were analyzed, and the literature related to PBS and primary RMS of the breast was reviewed. RESULTS We identified three primary breast RMS cases from our institution database, comprising 7.3% of PBS: one case each of spindle cell/sclerosing RMS (ssRMS), alveolar RMS (aRMS), and embryonal RMS (eRMS). All cases involved adolescents or young adults (14, 16, and 25 years, respectively) who underwent mastectomy or radiotherapy and were confirmed using immunohistochemical testing for myogenin, desmin, and myogenic differentiation. The ssRMS patient experienced recurrence at the operation site 4 months post-surgery despite undergoing concurrent chemoradiotherapy. The aRMS patient had multiple metastases at diagnosis and showed FAX3-FOXO1 fusion transcripts; she died 22 months after the diagnosis. The eRMS patient had enlarged axillary lymph nodes; post-radiotherapy, the lesion recurred as multiple metastases to the bone and lung. She died 18 months post-diagnosis. CONCLUSIONS Our experience on RMS cases suggests that spindle cell or small round cell malignancy in breasts of young female should raise suspicion for the possibility of primary or secondary RMS. To our knowledge, this is the second report of primary breast ssRMS and it may help clinicians who encounter this rare disease in the future.

Abstract
We report the first measurement of the neutron cross section on argon in the energy range of 100-800 MeV. The measurement was obtained with a 4.3-h exposure of the Mini-CAPTAIN detector to the WNR/LANSCE beam at LANL. The total cross section is measured from the attenuation coefficient of the neutron flux as it traverses the liquid argon volume. A set of 2631 candidate interactions is divided in bins of the neutron kinetic energy calculated from time-of-flight measurements. These interactions are reconstructed with custom-made algorithms specifically designed for the data in a time projection chamber the size of the Mini-CAPTAIN detector. The energy averaged cross section is 0.91±0.10(stat)±0.09(syst) b. A comparison of the measured cross section is made to the GEANT4 and FLUKA event generator packages, where the energy averaged cross sections in this range are 0.60 and 0.68 b, respectively.

Abstract
Abstract
Antibody-Coupled T cell Receptor (ACTR) is an autologous engineered T cell therapy developed to combine with tumor-targeting antibodies to exert potent anti-tumor immune responses and tumor cell killing. The ACTR construct is composed of the extracellular domain of CD16 fused to CD3ζ signaling and T cell co-stimulatory domains. ACTR-expressing T cells are universal in that they can be paired with a therapeutic antibody to target specific antigens on tumors. Unum has two ACTR constructs, ACTR087 and ACTR707, currently in clinical testing. ACTR087 and ACTR707 are being tested in combination with rituximab in subjects with CD20+ B cell lymphoma in two separate trials (NCT02776813 and NCT03189836, respectively). Preliminary data with ACTR087 + rituximab has demonstrated clinical proof-of-concept and a dose-response relationship in subjects with relapsed/refractory B cell lymphoma. ACTR087 is also being tested in combination with a novel BCMA-targeting antibody in subjects with multiple myeloma (NCT03266692).
While T cell therapies, such as chimeric antigen receptor (CAR) T cells, have demonstrated clinical activity in hematological cancers, the therapeutic potential of this approach has yet to be established in solid tumors. Challenges associated with targeting solid tumors with CAR-T cells include tumor antigen heterogeneity and antigen expression on normal tissues. HER2 is a well-established therapeutic target that is over-expressed in a number of cancer indications. HER2 is also expressed at low levels on normal epithelial cells, creating a risk for on-target/off-tumor toxicities of HER2-targeted CAR-T cells. Here we present nonclinical studies demonstrating that ACTR T cells in combination with trastuzumab have antigen density-dependent activity on HER2-expressing tumor cell lines, while trastuzumab-based CAR-T cells do not. We observed that ACTR + trastuzumab had robust activity against HER2-amplified tumor cells and more modest activity against non-amplified tumor cells, whereas HER2-targeting CAR-T cells had comparable activity against HER2-amplified and non-amplified tumor cells. On normal human primary cells, ACTR + trastuzumab had minimal activity in comparison to HER2 CAR-T cells, suggesting that ACTR + trastuzumab may exhibit a superior clinical therapeutic index. Furthermore, the activity of ACTR T cells against HER2-amplified tumor cells was titratable with antibody concentration, allowing for control of ACTR activity by modulation of trastuzumab concentration. Together, these data demonstrate the specificity of the ACTR T cell therapeutic approach to target HER2-amplified tumors and support clinical testing in combination with trastuzumab.
A phase 1, multicenter, single-arm, open-label dose escalation study, ATTCK-34-01, is proposed to evaluate ACTR T cells in combination with trastuzumab in subjects with advanced HER2-positive malignancies. The primary study objectives are to assess the safety and tolerability of the combination, and to define the recommended phase 2 dose combination for further study. Additional objectives include assessment of anti-tumor activity, ACTR T cell persistence and trastuzumab pharmacokinetics. Enrollment is expected to commence in early 2019.

Abstract
Abstract
Background: Oncogenic mutations are potential targets for therapeutic intervention in metastatic breast cancer (MBC). While tumor genotyping (TG) has been viewed as the gold standard for identifying oncogenic mutations, cell-free circulating tumor DNA (cfDNA) is emerging as an alternate technique. We previously reported the selection of matched therapy targeted to an actionable mutation based on either TG or cfDNA testing (Vidula N, ASCO, 2018). Therefore, we are now comparing TG and cfDNA results in MBC patients undergoing both tests to examine their relative utility in the selection of matched therapy.
Methods: Patients with MBC at an academic institution who underwent both TG (Next Generation Sequencing/NGS, institutional platform, 104 gene assay) and cfDNA testing (NGS/Guardant360, 73 gene assay) between 1/2016-10/2017 were identified. A chart review was conducted to identify tumor subtype, demographics, treatment, TG and cfDNA results, and clinical outcomes. The relative utility of these tests in the selection of matched therapy was determined, and linked with clinical outcomes (progression-free survival and overall survival).
Results: Thirty patients who underwent both TG and cfDNA testing were identified. The median age was 60 years, the majority (97%) had hormone receptor (HR) positive/HER2 negative disease, and most patients had recurrent disease (83.3%) at MBC diagnosis. The median number of therapies prior to obtaining either test was 1 (cfDNA range 0-9, TG range 0-8). The majority had simultaneous cfDNA and tumor genotyping testing (83.3%) versus sequential testing (16.7%). Twenty-four (80%) patients had actionable mutations detected by cfDNA compared to 19 (63.3%) patients with actionable mutations detected by TG. The median number of actionable mutations detected by cfDNA was 2 (range 0-11) compared with a median of 1 (range 0-4) detected by TG. Failure of TG occurred in 2 of 30 patients (6.7%) but no test failures were seen with cfDNA. Eleven of 30 patients (36.7%) had ≥ 1 concordant mutation via cfDNA and TG. Altogether, 12 out of 30 (40%) patients received matched therapy, 5 of which were based on cfDNA actionable mutations alone (ESR1, ERBB2, CCND1, and PIK3CA), and 7 based on cfDNA and TG results (ESR1, PIK3CA, STK11, and BRCA). Twelve of 24 (50%) patients with actionable cfDNA mutations went on to receive matched therapy compared with 7 of 19 (36.8%) patients with actionable TG results. Matched therapies included SERDs, inhibitors of CDK 4/6, PI3K, mTOR, HER2 directed therapy, and DNA damaging chemotherapy. The impact of matched therapy on survival outcomes will be presented at the meeting.
Conclusions: In patients undergoing both TG and cfDNA testing, both tests identify a significant cohort of HR+ MBC patients with actionable mutations, with greater detection of actionable mutations by cfDNA. Greater application of matched therapy occurred via cfDNA, which independently informed the selection of matched therapies. Further research is needed to prospectively evaluate the clinical utility of blood based genotyping assays versus TG for patients with MBC.

Association between long-term exposure of ambient air pollutants and cardiometabolic diseases: A 2012 Korean Community Health Survey. Nutr Metab Cardiovasc Dis 2019; 29:144-151. [PMID: 30595346 DOI: 10.1016/j.numecd.2018.09.008] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2018] [Revised: 09/18/2018] [Accepted: 09/19/2018] [Indexed: 12/21/2022]
Abstract
BACKGROUND AND AIM The associations of long-term exposure to particulate matter <10 μm in size (PM10), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone (O3) with cardiometabolic diseases (CMD) remain uncertain in the Korean population. Therefore, we sought to examine the associations between PM10, NO2, CO, SO2, and O3 and CMD using data collected from the Korean Community Health Survey. METHODS AND RESULTS We selected 100,867 adults aged 19 years or older who had lived in the same domicile for ≥10 years and surveyed them to collect data on socioeconomic characteristics; health-related behaviors; obesity; and physician-diagnosed CMD history, including hypertension, diabetes mellitus, dyslipidemia, stroke, myocardial infarction, and ischemic heart disease. We calculated interquartile ranges for PM10, NO2, CO, SO2, and O3 from the 10 year average concentrations (2003-2012). Hypertension, diabetes mellitus, and dyslipidemia were positively associated with PM10, NO2, CO, SO2, and O3 after adjusting for confounding factors. Obesity was positively associated with PM10, NO2, SO2, and O3. On the other hand, we found no associations between stroke, myocardial infarction, and ischemic heart disease and exposure to PM10, NO2, CO, SO2, and O3 in these subjects. In subjects aged ≥65 years, the risk of dyslipidemia was markedly increased under exposure to NO2 and CO compared to subjects aged <65 years. The risk of obesity was also significantly increased under exposure to PM10 and NO2. However, sex differences in these associations were not found. CONCLUSION Long-term exposure to PM10, NO2, CO, SO2, and O3 may be a risk factor of CMD in Korean adults.

Does Phase-Contrast Imaging through the Cerebral Aqueduct Predict the Outcome of Lumbar CSF Drainage or Shunt Surgery in Patients with Suspected Adult Hydrocephalus? AJNR Am J Neuroradiol 2018; 39:2224-2230.

Abstract
BACKGROUND AND PURPOSE Radiologic imaging plays a key role in diagnosing chronic adult hydrocephalus, but its role in predicting prognosis is still controversial. We sought to evaluate the effectiveness of cardiac-gated phase-contrast MR imaging through the cerebral aqueduct in predicting the clinical response to diagnostic lumbar puncture/lumbar drainage and shunt surgery in suspected adult hydrocephalus. MATERIALS AND METHODS In this retrospective study, the phase-contrast MR imaging of 185 patients with suspected chronic adult hydrocephalus was evaluated using the CSF Flow software package. Decision-making for shunt placement was performed in this cohort on the basis of clinical assessment alone without the availability of quantitative phase-contrast MR imaging results. We recorded the response to lumbar puncture or lumbar drainage and shunt surgery using quantitative tests such as the Tinetti Test, the Timed Up and Go, and the Mini-Mental State Examination and qualitative measures of gait, urinary, and cognitive symptom improvement before and after lumbar puncture/lumbar drainage and shunt surgery. Quantitative analysis of phase-contrast MR imaging was compared with clinical outcome measures. RESULTS Both CSF stroke volume and flow rate overlapped between lumbar puncture/lumbar drainage responders and nonresponders. There was also a significant overlap between shunt responders and nonresponders. Aqueductal stroke volume or flow rate alone was a poor predictor of lumbar puncture/lumbar drainage and shunt surgery response. Quantitative clinical measures after lumbar puncture/lumbar drainage were better predictors of shunt response. CONCLUSIONS This study suggests that the results of phase-contrast MR imaging through the cerebral aqueduct alone should not be used to select patients for diagnostic or therapeutic CSF diversion.

Does the Presence or Absence of DESH Predict Outcomes in Adult Hydrocephalus? AJNR Am J Neuroradiol 2018; 39:2022-2026. [PMID: 30361433 DOI: 10.3174/ajnr.a5820] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2018] [Accepted: 08/10/2018] [Indexed: 11/07/2022]
Abstract
BACKGROUND AND PURPOSE The DESH (disproportionately enlarged subarachnoid-space hydrocephalus) pattern of "tight high-convexity and medial subarachnoid spaces, and enlarged Sylvian fissures with ventriculomegaly" is used to determine which patients undergo an operation for adult hydrocephalus at many centers. Our aim was to review adult hydrocephalus cases when DESH has not been a criterion for an operation to determine the prevalence of DESH among the cohort and compare the surgical outcomes in the presence or absence of DESH. MATERIALS AND METHODS A retrospective cohort study was conducted at a single institution (Johns Hopkins Hospital) to include patients surgically treated for adult hydrocephalus between 2003 and 2014 drawn from a data base of patients who had undergone standardized hydrocephalus protocol MR imaging. Preoperative imaging was reviewed by 2 blinded neuroradiologists to characterize the presence of DESH. Preoperative and postoperative clinical symptomatology was recorded. Frequencies were compared using the Fisher exact test, and nonparametric means were compared using the Mann-Whitney U Test. RESULTS One hundred thirty-three subjects were identified and included (96 DESH absent, 37 DESH present). Shunting led to significant improvement in gait and urinary and cognitive symptoms for the overall cohort and for patients with and without DESH (P < .05). The Fisher exact test did not demonstrate any significant differences in either gait or urinary or cognitive symptom improvement between patients with or without DESH (P > .05). CONCLUSIONS The current study demonstrated symptom improvement in patients with adult hydrocephalus following shunting, with no significant differences between subjects with and without DESH. Thus, shunt insertion for patients with adult hydrocephalus should not rely solely on the presence of preoperative DESH findings.
