Abstract
Despite the five million children in the U.S. with an incarcerated parent, there is limited research on risk and protective factors for this population. We analyzed data from the National Survey for Children's Health (2018) to: (1) examine associations among parental incarceration and other adverse childhood experiences (ACEs), (2) characterize the association between parental incarceration and youth mental health outcomes, (3) examine differences in positive childhood experiences (PCEs; collective socialization, community engagement, neighborhood amenities, and family problem solving) by parental incarceration status, (4) examine whether PCEs were protective against mental health problems and if there was an interaction with parental incarceration status, and (5) examine the interaction between PCEs, parental incarceration, and ACEs on mental health problems. Results revealed that children with incarcerated parents had higher odds of experiencing other ACEs, higher odds of having mental health problems, and experienced fewer PCEs compared to children without incarcerated parents. Further, although PCEs were associated with a lower odds of mental health problems for both children with and without incarcerated parents, they did not mitigate the negative impact of parental incarceration on mental health outcomes. While PCEs attenuated the association between ACEs and mental health, parental incarceration status did not significantly moderate the interaction. These results highlight vulnerabilities and potential protective factors for children with incarcerated parents and have important implications for the development of multilevel intervention strategies that seek to promote resilience and reduce risk for this population.

Abstract
PURPOSE To determine, in women with primary operable breast cancer, if preoperative doxorubicin (Adriamycin) and cyclophosphamide (Cytoxan; AC) therapy yields a better outcome than postoperative AC therapy, if a relationship exists between outcome and tumor response to preoperative chemotherapy, and if such therapy results in the performance of more lumpectomies. PATIENTS AND METHODS Women (1,523) enrolled onto National Surgical Adjuvant Breast and Bowel Project (NSABP) B-18 were randomly assigned to preoperative or postoperative AC therapy. Clinical tumor response to preoperative therapy was graded as complete (cCR), partial (cPR), or no response (cNR). Tumors with a cCR were further categorized as either pathologic complete response (pCR) or invasive cells (pINV). Disease-free survival (DFS), distant disease-free survival (DDFS), and survival were estimated through 5 years and compared between treatment groups. In the preoperative arm, proportional-hazards models were used to investigate the relationship between outcome and tumor response. RESULTS There was no significant difference in DFS, DDFS, or survival (P = .99, .70, and .83, respectively) among patients in either group. More patients treated preoperatively than postoperatively underwent lumpectomy and radiation therapy (67.8% v 59.8%, respectively). Rates of ipsilateral breast tumor recurrence (IBTR) after lumpectomy were similar in both groups (7.9% and 5.8%, respectively; P = .23). Outcome was better in women whose tumors showed a pCR than in those with a pINV, cPR, or cNR (relapse-free survival [RFS] rates, 85.7%, 76.9%, 68.1%, and 63.9%, respectively; P < .0001), even when baseline prognostic variables were controlled. When prognostic models were compared for each treatment group, the preoperative model, which included breast tumor response as a variable, discriminated outcome among patients to about the same degree as the postoperative model. CONCLUSION Preoperative chemotherapy is as effective as postoperative chemotherapy, permits more lumpectomies, is appropriate for the treatment of certain patients with stages I and II disease, and can be used to study breast cancer biology. Tumor response to preoperative chemotherapy correlates with outcome and could be a surrogate for evaluating the effect of chemotherapy on micrometastases; however, knowledge of such a response provided little prognostic information beyond that which resulted from postoperative therapy.

Abstract
BackgroundToday, there are still no DMARDs licensed for primary Sjögren Syndrome (pSS) patients. Among the explanations, are the limitations of current outcome measures used as primary endpoints: e.g; high placebo response rate, evaluation of either symptoms or systemic activity, and important features not being assessed. The NECESSITY consortium (https://www.necessity-h2020.eu/), including pSS experts from academia, pharmaceutical industry and patient groups formed to develop a new composite responder index, the Sjögren’s Tool for Assessing Response (STAR) that solve the issues of current outcome measures in pSS and is intended for use in clinical trials as an efficacy endpoint.ObjectivesTo develop a composite responder index in primary Sjögren’s syndrome (pSS): the STAR.MethodsTo develop the STAR, the NECESSITY consortium used data-driven methods, based on 9 randomized controlled trials (RCTs), and consensus techniques, involving 78 experts and 20 patients. Based on reanalysis of rituximab trials (TRACTISS and TEARS) and literature review, the Delphi panel identified a core set of domains to include in the STAR, with their respective outcome measures. STAR options combining these domains were designed and proposed to the panel to select and improve them. For each STAR option, sensitivity to change was estimated by the C-index (derived from Effect size) in all 9 RCTs. Delphi rounds were run for selecting STAR among these options. The Delphi panel also voted to classify trials as positive, negative or “in between” in regards to primary but also key secondary endpoints. For the options remaining before the final vote, meta-analyses of the RCTs were performed separately for positive and “in between” trials together, and for negative trials.ResultsThe Delphi panel identified 5 core domains (systemic activity, patient symptoms, lachrymal gland function, salivary gland function and biological parameters), and 227 STAR options, combining these domains, were selected to be tested for sensitivity to change. After two Delphi rounds, meta-analyses of the 20 remaining options were performed. The candidate STAR was selected by a final vote based on metrological properties and clinical relevance. In positive/in between trials, candidate STAR detected a difference between arms (OR 3.29, 95%-CI [2.07;5.22], whereas it did not in negative trials (OR 1.53, 95%-CI [0.81;2.91]).ConclusionThe candidate STAR is a composite responder index, including in a single tool all main disease features, and is designed for use as a primary endpoint in pSS RCTs. Its rigorous and consensual development process ensures its face and content validity. The candidate STAR showed good sensitivity and specificity to change. The candidate STAR will be prospectively validated in a dedicated three arms RCT of the NECESSITY consortium that will evaluate combination of synthetic DMARDs (hydroxychloroquine + lefunomide or hydroxychloroquine + mycophenolate vs placebo). We encourage the use of STAR in any ongoing and future trials.Table 1.Candidate STARDomainPointDefinition of responseSystemic activity3Decrease of clinESSDAI ≥ 3Patient reported outcome3Decrease of ESSPRI ≥ 1 point or ≥ 15%Lachrymal gland function1Schirmer:If abnormal score at baseline: increase ≥ 5 mm from baselineIf normal score at baseline: no change to abnormalOrOcular Staining Score:If abnormal score at baseline: decrease ≥ 2 points from baselineIf normal score at baseline: no change to abnormalSalivary gland function1Unstimulated Whole Salivary Flow:If score > 0 at baseline: increase ≥ 25% from baselineIf score is 0 at baseline: any increase from baselineorUltrasound:Decrease ≥ 25% in total Hocevar score from baselineBiological1Serum IgG levels: decrease ≥ 10%orRheumatoid Factor levels: decrease ≥ 25%Candidate STAR responder≥ 5 pointsESSDAI: EULAR Sjögren syndrome disease activity index;

Abstract
Termites are major decomposers in terrestrial ecosystems and the second most diverse lineage of social insects. The Kalotermitidae form the second-largest termite family and are distributed across tropical and subtropical ecosystems, where they typically live in small colonies confined to single wood items inhabited by individuals with no foraging abilities. How the Kalotermitidae have acquired their global distribution patterns remains unresolved. Similarly, it is unclear whether foraging is ancestral to Kalotermitidae or was secondarily acquired in a few species. These questions can be addressed in a phylogenetic framework. We inferred time-calibrated phylogenetic trees of Kalotermitidae using mitochondrial genomes of ∼120 species, about 27% of kalotermitid diversity, including representatives of 21 of the 23 kalotermitid genera. Our mitochondrial genome phylogenetic trees were corroborated by phylogenies inferred from nuclear ultraconserved elements derived from a subset of 28 species. We found that extant kalotermitids shared a common ancestor 84 Ma (75–93 Ma 95% highest posterior density), indicating that a few disjunctions among early-diverging kalotermitid lineages may predate Gondwana breakup. However, most of the ∼40 disjunctions among biogeographic realms were dated at <50 Ma, indicating that transoceanic dispersals, and more recently human-mediated dispersals, have been the major drivers of the global distribution of Kalotermitidae. Our phylogeny also revealed that the capacity to forage is often found in early-diverging kalotermitid lineages, implying the ancestors of Kalotermitidae were able to forage among multiple wood pieces. Our phylogenetic estimates provide a platform for critical taxonomic revision and future comparative analyses of Kalotermitidae.

Abstract
Women with preeclampsia (PE) have a greater risk of developing hypertension, cardiovascular disease (CVD), and renal disease later in life. Angiotensin II type I receptor agonistic autoantibodies (AT1-AAs) are elevated in women with PE during pregnancy and up to 2-year postpartum (PP), and in the reduced uterine perfusion pressure (RUPP) rat model of PE. Blockade of AT1-AA with a specific 7 amino acid peptide binding sequence (‘n7AAc’) improves pathophysiology observed in RUPP rats; however, the long-term effects of AT1-AA inhibition in PP is unknown. Pregnant Sprague Dawley rats were divided into three groups: normal pregnant (NP) (n = 16), RUPP (n = 15), and RUPP + ‘n7AAc’ (n = 16). Gestational day 14, RUPP surgery was performed and ‘n7AAc’ (144 μg/day) administered via osmotic minipump. At 10-week PP, mean arterial pressure (MAP), renal glomerular filtration rate (GFR) and cardiac functions, and cardiac mitochondria function were assessed. MAP was elevated PP in RUPP vs. NP (126 ± 4 vs. 116 ± 3 mmHg, p < 0.05), but was normalized in in RUPP + ‘n7AAc’ (109 ± 3 mmHg) vs. RUPP (p < 0.05). PP heart size was reduced by RUPP + ’n7AAc’ vs. RUPP rats (p < 0.05). Complex IV protein abundance and enzymatic activity, along with glutamate/malate-driven respiration (complexes I, III, and IV), were reduced in the heart of RUPP vs. NP rats which was prevented with ‘n7AAc’. AT1-AA inhibition during pregnancy not only improves blood pressure and pathophysiology of PE in rats during pregnancy, but also long-term changes in blood pressure, cardiac hypertrophy, and cardiac mitochondrial function PP.

Abstract
Pure spin currents can be generated via thermal excitations of magnons. These magnon spin currents serve as carriers of information in insulating materials, and controlling them using electrical means may enable energy efficient information processing. Here, we demonstrate electric field control of magnon spin currents in the antiferromagnetic insulator Cr2O3. We show that the thermally driven magnon spin currents reveal a spin-flop transition in thin-film Cr2O3. Crucially, this spin-flop can be turned on or off by applying an electric field across the thickness of the film. Using this tunability, we demonstrate electric field–induced switching of the polarization of magnon spin currents by varying only a gate voltage while at a fixed magnetic field. We propose a model considering an electric field–dependent spin-flop transition, arising from a change in sublattice magnetizations via a magnetoelectric coupling. These results provide a different approach toward controlling magnon spin current in antiferromagnets.

Abstract
Using a q+ atomic force microscopy at low temperature, a sexiphenyl molecule is slid across an atomically flat Ag(111) surface along the direction parallel to its molecular axis and sideways to the axis. Despite identical contact area and underlying surface geometry, the lateral force required to move the molecule in the direction parallel to its molecular axis is found to be about half of that required to move it sideways. The origin of the lateral force anisotropy observed here is traced to the one-dimensional shape of the molecule, which is further confirmed by molecular dynamics simulations. We also demonstrate that scanning tunneling microscopy can be used to determine the comparative lateral force qualitatively. The observed one-dimensional lateral force anisotropy may have important implications in atomic scale frictional phenomena on materials surfaces.

Abstract
Introduction:Women with preeclampsia (PE) and reduced uterine perfusion pressure (RUPP) pre-clinical rat model of PE have elevated angiotensin II type 1 receptor agonistic autoantibodies (AT1-AA) and cerebrovascular dysfunction. Methods:Sprague Dawley rats had RUPP surgery with/without AT1-AA inhibitor ('n7AAc'144 μg/day) osmotic minipumps. Mean arterial pressure (MAP), CBF autoregulation, blood brain barrier (BBB) permeability, cerebral edema, oxidative stress, and eNOS were assessed. Results:'n7AAc' improved MAP, restored CBF autoregulation, prevented cerebral edema, elevated oxidative stress, and increased phosphorylated eNOS protein in RUPP rats. Conclusion:Inhibiting the AT1-AA in placental ischemic rats prevents hypertension, cerebrovascular dysfunction, and improves cerebral metabolic function.

Abstract
Background:Sjögren’s syndrome (SS) is a systemic autoimmune disease whose main characteristic is involvement of the exocrine glandular system. Thus, its most common clinical manifestation is eye and mouth dryness which, alongside fatigue and pain, contributes to poor health-related quality of life (HRQoL). A growing body of evidence recognises the adipose tissue as an active endocrine organ secreting bioactive mediators involved in metabolic and inflammatory disorders. A relationship between obesity and symptoms in SS has not yet been elucidated.Objectives:To explore potential associations between obesity-related immune-metabolic biomarkers and clinical symptoms in SS and sicca patients.Methods:Proteomics analysis of 184 cardio-immuno-metabolic proteins was assessed on sera from 53 SS (50 females (F), 3 males (M); mean age 54 years) and 60 sicca (56 F, 4 M; mean age 57 years) patients. Participants were enrolled in the Birmingham Optimising Assessment in Sjögren`s Syndrome (OASIS) cohort and examinations included the EULAR SS Patient Reported Index (ESSPRI), Schirmer’s test, unstimulated whole saliva, minor labial salivary gland biopsy, EuroQoL-5 dimension (EQ-5D) tool, immunological parameters, body max index (BMI) and Hb1Ac. Participants with SS fulfilled 2016 ACR/EULAR criteria. Non-SS sicca patients were anti-Ro antibody negative, displayed objective oral and/or ocular dryness, and did not have a physician diagnosis for SS. Linear regression analysis and univariate models were performed to identify the key predictors of symptoms.Results:HRQoL as measured as EQ-5D utility values, symptoms as assessed by ESSPRI, and BMI did not differ between the SS and sicca group. However, strong correlations between BMI (or fat or fat-free mass) and EQ-5D and ESSPRI scores were found in the sicca but not in the SS group. Among several proteins investigated, ADM, TNFRSF13B, FGF23, IL10RB, CD5, CD40, IL1RA, TNRSFN9, TNFRSF10A, TNFRSF11A, TRAILR2, GAL9, SPON2, ACE2, LEP, CD4, IL12B, SLAMF1, PD-L1 positively correlated with symptoms in the sicca group (R ≥ 0.3; Holm’s adjusted P ≤ 0.05). Adrenomedullin (ADM) showed the strongest correlation with ESSPRI (R = 0.56; P < 0.0001); age (R = 0.45; P = 0.0003); BMI (R = 0.43, P = 0.0008); Ocular Surface Disease Index (R = 0.32, P = 0.03); EQ-5D utility value (R = -0.45, P = 0.001) and VAS patient (R = -0.41, P = 0.008). There was no association between ADM and gender, Schirmer`s test, disease and symptom duration (P > 0.05). ADM was independently associated with ESSPRI scores in non-SS sicca patients when corrected for BMI, age, HbA1c, depression and anxiety scores. None of the above mentioned proteins correlated with clinical symptoms in the SS group.Conclusion:The study suggests that obesity-related immune-metabolic factors may play a role in regulating the symptoms in non-SS sicca patients. ADM appears to be a strong independent predictor of symptoms in these patients but not in SS.Disclosure of Interests:Valentina Pucino: None declared, Jason D.

Abstract
Background:The palatine tonsils are secondary lymphoid-organs that serve as the first line of defense against pathogens. Whether history of tonsillectomy (TE) is associated with the phenotype of Sjögren`s syndrome (SjS) has not been investigated to date.Objectives:To test whether TE is linked to SjS phenotype and disease activity scores.Methods:A total of 183 patients from the Optimising Assessment in Sjögren`s Syndrome (OASIS) cohort with SjS or non-SjS sicca syndrome were analysed. Patients with SjS fulfilled 2016 ACR/EULAR classification for primary SjS; sicca patients had objective and/or subjective dryness, but were anti-Ro/SSA negative and had no physician diagnosis of SjS. One SjS patient who had TE around the time of symptom onset was excluded.Results:Of the total cohort, 116 were diagnosed with SjS (86.2% SSA/Ro positive) and 67 with non-SjS sicca syndrome. Overall, 29% (53/183) had TE; 24.1% of the SjS patients (28/116) and 37.3% of the sicca patients (25/67). The prevalence of TE was higher in sicca than in SjS (p=0.043). The median age at TE was 8 (range 3-50) years and did not differ between SjS and sicca patients (p=0.629). Neither age at first symptoms (p=0.093) nor disease duration (p=0.623) were associated with TE in patients with SjS. SjS patients with TE showed a higher average histological focus score (2.1 (1.2-2.8) vs. 1.3 (0.0-4.3); p=0.049), and were more likely to have activity in the glandular (53.6 vs. 20.5%; p=0.001) and constitutional (39.3 vs. 14.9%, p=0.014) domains of the ESSDAI, and lower levels of IgG (12.2 (7.8-35.6) vs. 15.6 (5.7-56.4) g/l; p=0.012) and IgA (2.3 (0.9-6.6) vs. 2.9 (0.7-9.4) g/l; p=0.032). Whereas there was no difference in EQ5D utility values (p=0.718), VAS global health was significantly lower in the patients with SjS who had TE (58 (10-78) vs. 70 (10-97); p=0.021). There was no association between the status of TE and autoantibodies (SSA, SSB, RF), lachrymal and salivary glands function (Schirmer`s test, unstimulated saliva flow), complement (C3, C4), serum levels of free light chains, β2-microglobulin, ESSPRI, or total ESSDAI (all p-values >0.1). Of 181 patients, 12.7% (23/283) had appendectomy (AE); 10.5% (12/114) of the SjS patients and 16.4 %(11/67) of the sicca patients (p=0.258). With the exception of lower unstimulated salivary flow (0.086 (0.01-0.43) vs. 0.11 (0.0-1.3) ml/min; p=0.026) in SjS patients with AE, there were no differences in disease phenotype between SjS patients with and without AE (all p-values >0.1).Conclusion:History of TE in SjS is associated with higher average focus scores and with glandular swelling. It could be speculated that the absence of palatine tonsils is compensated by enhanced lymphocytic infiltrates in the salivary glands. Further research is required to determine if TE is a risk factor for both SjS and non-SjS sicca and to determine the role of the tonsils in the generation of hypergammaglobulinaemia in SjS.Disclosure of Interests:Florian Kollert Employee of: Novartis, Valentina Pucino: None declared, Saaeha Rauz: None declared, Andrea Richard: None declared, Jon Higham: None declared, Ana Povedo-Gallego: None declared, Rachel M.

Abstract
OBJECTIVE Major salivary gland ultrasonography (SGUS) is widely used for the diagnosis of primary Sjögren's syndrome (pSS). Our objective was to assess the contribution of SGUS compared to other items of the 2016 ACR/EULAR pSS classification criteria, based on expert opinion. METHODS A secure web-based relational database was used by 24 experts from 14 countries to assess 512 realistic vignettes developed from data of patients with suspected pSS. Each vignette provided classification criteria items and information on history, clinical symptoms and SGUS findings. Each expert assessed 64 vignettes, and each vignette was assessed by 3 experts. A diagnosis of pSS was defined according to at least 2 of 3 experts. Validation was performed in the independent French DiapSS cohort of patients with suspected pSS. RESULTS A criteria-based pSS diagnosis and SGUS findings were independently associated with an expert diagnosis of pSS (P < 0.001). The derived diagnostic weights of individual items in the 2016 ACR/EULAR criteria including SGUS were as follows: anti-SSA, 3; focus score ≥ 1, 3; SGUS score ≥ 2, 1; positive Schirmer's test, 1; dry mouth, 1; and salivary flow rate < 0.1 mL/min, 1. The corrected C statistic area under the curve for the new weighted score was 0.96. Adding SGUS improves the sensitivity from 90.2 % to 95.6% with a quite similar specificity 84.1% versus 82.6%. Results were similar in the DiapSS cohort: adding SGUS improves the sensitivity from 87% to 93%. CONCLUSION SGUS had similar weight compared to minor items, and its addition improves the performance of the 2016 ACR/EULAR classification criteria.

Abstract
A collaborative study involving 26 laboratories and 5 food types was performed to compare the TECRA Listeria Visual Immunoassay (TLVIA) with standard culture methods. Three foods (lettuce, ice cream, and fish fillets), under the jurisdiction of the U.S. Food and Drug Administration, and 2 foods (cooked chicken and cooked ground turkey), under the jurisdiction of the U.S. Department of Agriculture, were used to determine the effectiveness of the TLVIA. Of the 900 samples tested, 300 were inoculated with low levels (1-5 cells/25 g) of Listeria spp. and 300 were inoculated with high levels of Listeria spp. (10-50 cells/25 g). Method agreement between the conventional culture methods and TLVIA (visual) was 94.7%. Method agreement between the conventional culture methods and TLVIA (reader) was 93.6%. The colorimetric polyclonal enzyme immunoassay (TLVIA) for detection of Listeria in foods has been adopted first action by AOAC INTERNATIONAL.

Abstract
Charge density waves and negative differential resistance are seemingly unconnected physical phenomena. The former is an ordered quantum fluid of electrons, intensely investigated for its relation with superconductivity, while the latter receives much attention for its potential applications in electronics. Here we show that these two phenomena can not only coexist but also that the localized electronic states of the charge density wave are essential to induce negative differential resistance in a transition metal dichalcogenide, 1T-TaS2. Using scanning tunneling microscopy and spectroscopy, we report the observation of negative differential resistance in the commensurate charge density wave state of 1T-TaS2. The observed phenomenon is explained by the interplay of interlayer and intra-layer tunneling with the participation of the atomically localized states of the charge density wave maxima and minima. We demonstrate that lattice defects can locally affect the coupling between the layers and are therefore a mechanism to realize NDR in these materials.

Abstract
Women with preeclampsia (PE) have a risk of developing cardiovascular diseases (CVD) later in life. The angiotensin II type I receptor agonistic autoantibodies (AT1-AAs) are elevated in women with PE, PE women 2 years post-partum (PP), and the reduced uterine perfusion pressure (RUPP) rat model of PE. Blockade of the AT1-AA by using a specific binding seven amino acid peptide sequence (7AA) improves the pathology of PE in RUPP rats. The long-term effects of AT1-AA inhibition on blood pressure, NK cell activation, heart mitochondria (mt) proteins, and CVD in the RUPP model PP is unknown. Therefore, we hypothesized that PP RUPP rats have elevated blood pressure, NK cell activation, and changes in heart mt proteins, which will be prevented in RUPP rats administered the 7AA during pregnancy.
Methods:
Pregnant Sprague Dawley rats were divided into groups; normal pregnant (NP) (n=7), RUPP (n=10), and RUPP+7AA (n=9). Gestational day 14, RUPP surgery was performed and 7AA (2 μg/ml) administered via minipump.
Results:
At 8 and 10 weeks (wks) PP, blood pressure (MAP), blood, and hearts were collected. NK cells were quantified by flow cytometry. At 8 wks PP, MAP was elevated in RUPP vs. NP (130±2 vs. 123±4 mmHg, ns), and RUPP+7AA (124±4 mmHg) treatment prevented this increase. At 10 wks, MAP was elevated in RUPP vs NP (133±5 vs. 120±5 mmHg, p=0.08), with a significant decrease in MAP in RUPP+7AA (107±6 mmHg) vs. RUPP (p<0.05). Total circulating NK cells were increased in RUPP vs NP (45±9. vs. 29± 8% gated cells, ns), which was prevented in RUPP+7AA (19±16 % gated cells) at 8 wks PP. Hearts were enlarged with RUPP vs NP (0.41±0.04 vs. 0.36±0.02g/100gBW, ns), which was normalized in RUPP+7AA (0.34±0.02g/100gBW). Previous studies show that during pregnancy complex IV is significantly lower along with a decrease mt function in RUPP vs NP. Complex IV mt proteins in the heart were elevated in RUPP+7AA vs. RUPP (5.5±1.7 vs. 3.0±0.2 AU, ns).
Conclusion:
In summary, PP PE rats have an increase in MAP, NK cells, and larger hearts. AT1-AA inhibition restores complex IV mt levels and improves HTN, immune activation, and cardiac hypertrophy PP. This study highlights the importance of AT1-AA inhibition during PE to prevent CVD later in life.

Abstract
Protected areas (PAs) are fundamental for biodiversity conservation, yet their impacts on nearby residents are contested. We synthesized environmental and socioeconomic conditions of >87,000 children in >60,000 households situated either near or far from >600 PAs within 34 developing countries. We used quasi-experimental hierarchical regression to isolate the impact of living near a PA on several aspects of human well-being. Households near PAs with tourism also had higher wealth levels (by 17%) and a lower likelihood of poverty (by 16%) than similar households living far from PAs. Children under 5 years old living near multiple-use PAs with tourism also had higher height-for-age scores (by 10%) and were less likely to be stunted (by 13%) than similar children living far from PAs. For the largest and most comprehensive socioeconomic-environmental dataset yet assembled, we found no evidence of negative PA impacts and consistent statistical evidence to suggest PAs can positively affect human well-being.

Abstract
NASA's Orbiting Carbon Observatory-2 (OCO-2) mission was motivated by the need to diagnose how the increasing concentration of atmospheric carbon dioxide (CO2) is altering the productivity of the biosphere and the uptake of CO2 by the oceans. Launched on 2 July 2014, OCO-2 provides retrievals of the column-averaged CO2 dry-air mole fraction ([Formula: see text]) as well as the fluorescence from chlorophyll in terrestrial plants. The seasonal pattern of uptake by the terrestrial biosphere is recorded in fluorescence and the drawdown of [Formula: see text] during summer. Launched just before one of the most intense El Niños of the past century, OCO-2 measurements of [Formula: see text] and fluorescence record the impact of the large change in ocean temperature and rainfall on uptake and release of CO2 by the oceans and biosphere.

Abstract
We present a practical, generic, easy-to-use framework for the implementation of new radiation therapy technologies and treatment techniques in low-income countries. The framework is intended to standardize the implementation process, reduce the effort involved in generating an implementation strategy, and provide improved patient safety by reducing the likelihood that steps are missed during the implementation process. The 10 steps in the framework provide a practical approach to implementation. The steps are, 1) Site and resource assessment, 2) Evaluation of equipment and funding, 3) Establishing timelines, 4) Defining the treatment process, 5) Equipment commissioning, 6) Training and competency assessment, 7) Prospective risk analysis, 8) System testing, 9) External dosimetric audit and incident learning, and 10) Support and follow-up. For each step, practical advice for completing the step is provided, as well as links to helpful supplementary material. An associated checklist is provided that can be used to track progress through the steps in the framework. While the emphasis of this paper is on addressing the needs of low-income countries, the concepts also apply in high-income countries.

Abstract
OBJECTIVE The purpose of this study was to seek radiation dose responses separately for primary hepatocellular carcinoma (HCC) and metastatic (MET) colorectal liver tumours to establish tumour control probabilities (TCPs) for radiotherapy (RT) of liver tumours. METHODS The records of 36 HCC and 26 MET colorectal liver tumour patients were reviewed. The median dose per fraction and total dose were 4 Gy (2-10 Gy) and 52 Gy (29-83 Gy) for the HCC group and 3.6 Gy (2.0-13.0 Gy) and 55 Gy (30-80 Gy) for the MET group, respectively. Median tumour diameter was 6.6 cm (3.0-18.0 cm) and 5.0 cm (1.0-13.0 cm) for the HCC and MET groups, respectively. A logistic TCP model was fitted to the response data for each group using the maximum likelihood method. RESULTS 50% and 90% probabilities of 6-month local control were estimated to be achievable by 2 Gy per fraction equivalent doses (α/β=10 Gy) of 53 Gy and 84 Gy for the HCC group and 70 Gy and 95 Gy for the MET group, respectively. Actuarial 1-year local control for the HCC and MET groups was 65% (45-85%) and 32% (6-58%), respectively, whereas median time to failure was 543 days (374-711 days) and 183 days (72-294 days), respectively. CONCLUSION Dose-response relationships were found and modelled for the HCC and MET patient groups, with a higher dose required to control MET tumours. RT offers better local control for HCC than for MET colorectal liver tumours at our institution. ADVANCES IN KNOWLEDGE An improved understanding of radiation dose-response relationships for primary and MET colorectal liver tumours will help inform future dose prescriptions.

Abstract
BACKGROUND Certain jurisdictions in Canada legally require that physicians report unfit drivers. Physician attitudes and patterns of practice have yet to be evaluated in Canada for patients with brain tumours. METHODS We conducted a survey of 97 radiation oncologists, eliciting demographics, knowledge of reporting laws, and attitudes on reporting guidelines for unfit drivers. Eight scenarios with varying disability levels were presented to determine the likelihood of a patient being reported as unfit to drive. Statistical comparisons were made using the Fisher exact test. RESULTS Of physicians approached, 99% responded, and 97 physicians participated. Most respondents (87%) felt that laws in their province governing the reporting of medically unfit drivers were unclear. Of the responding physicians, 23 (24%) were unable to correctly identify whether their province had mandatory reporting legislation. Physicians from provinces without mandatory reporting legislation were significantly less likely to consider reporting patients to provincial authorities (p = 0.001), and for all clinical scenarios, the likelihood of reporting significantly depended on the physician's provincial legal obligations. CONCLUSIONS The presence of provincial legislation is of primary importance in determining whether physicians will report brain tumour patients to drivers' licensing authorities. In Canada, clear guidelines have to be developed to help in the assessment of whether brain tumour patients should drive.

Abstract
PURPOSE To provide a retrospective analysis of the efficacy of hyperbaric oxygen therapy (HBOT) for treating hemorrhagic cystitis (HC) and proctitis secondary to pelvic- and prostate-only radiotherapy. METHODS AND MATERIALS Nineteen patients were treated with HBOT for radiation-induced HC and proctitis. The median age at treatment was 66 years (range, 15-84 years). The range of external-beam radiation delivered was 50.0-75.6 Gy. Bleeding must have been refractory to other therapies. Patients received 100% oxygen at 2.0 atmospheres absolute pressure for 90-120 min per treatment in a monoplace chamber. Symptoms were retrospectively scored according to the Late Effects of Normal Tissues-Subjective, Objective, Management, Analytic (LENT-SOMA) scale to evaluate short-term efficacy. Recurrence of hematuria/hematochezia was used to assess long-term efficacy. RESULTS Four of the 19 patients were lost to follow-up. Fifteen patients were evaluated and received a mean of 29.8 dives: 11 developed HC and 4 proctitis. All patients experienced a reduction in their LENT-SOMA score. After completion of HBOT, the mean LENT-SOMA score was reduced from 0.78 to 0.20 in patients with HC and from 0.66 to 0.26 in patients with proctitis. Median follow-up was 39 months (range, 7-70 months). No cases of hematuria were refractory to HBOT. Complete resolution of hematuria was seen in 81% (n = 9) and partial response in 18% (n = 2). Recurrence of hematuria occurred in 36% (n = 4) after a median of 10 months. Complete resolution of hematochezia was seen in 50% (n = 2), partial response in 25% (n = 1), and refractory bleeding in 25% (n = 1). CONCLUSIONS Hyperbaric oxygen therapy is appropriate for radiation-induced HC once less time-consuming therapies have failed to resolve the bleeding. In these conditions, HBOT is efficacious in the short and long term, with minimal side effects.

Abstract
PURPOSE Because of the risk of skin toxicity with single dwell position, single-lumen brachytherapy devices are sometimes contraindicated for tumor cavities 5-7mm from the skin surface. We discuss the use of multicatheter device to treat patients with tumor bed-to-skin distances <7mm. METHODS AND MATERIALS We treated 117 patients with accelerated partial-breast irradiation brachytherapy: 77 single-lumen and 40 multicatheter devices. A subset of 12 patients treated with SAVI(®) had bed-to-skin spacing <7mm. All patients had Tis-2N0 ductal carcinoma with negative margins. A total dose of 34.0Gy in 10 fractions was delivered twice daily. Planning target volume was created using computed tomography-based three-dimensional planning with a 1.0-cm expansion of the lumpectomy cavity. Skin dose was measured dosimetrically, with skin constraints <125% of the prescription. Toxicities were graded, and patients were assessed at various intervals. RESULTS Of the patients treated with the multicatheter device, 0% (0/12) had their device pulled. At 2 weeks after treatment, fewer than 50% of the patients had skin toxicities of Grades 1-2, all of which resolved by 6 months. The cosmetic outcome was good to excellent at followup. CONCLUSIONS Multicatheter devices permit well-tolerated accelerated partial-breast irradiation in patients with tumor cavities near the skin surface for which the single-lumen device may not be appropriate.

Abstract
We have investigated the effects of thermal annealing on ex-situ chemically vapor deposited submonolayer graphene islands on polycrystalline Cu foil at the atomic-scale using ultrahigh vacuum scanning tunneling microscopy. Low-temperature annealed graphene islands on Cu foil (at ∼430 °C) exhibit predominantly striped Moiré patterns, indicating a relatively weak interaction between graphene and the underlying polycrystalline Cu foil. Rapid high-temperature annealing of the sample (at 700-800 °C) gives rise to the removal of Cu oxide and the recovery of crystallographic features of the copper that surrounds the intact graphene. These experimental observations of continuous crystalline features between the underlying copper (beneath the graphene islands) and the surrounding exposed copper areas revealed by high-temperature annealing demonstrates the impenetrable nature of graphene and its potential application as a protective layer against corrosion.
