1. II. A GR Source Term $T^{\mu \nu}$ For Dark Matter

Abstract

Two forms are suggested for the energy-momentum source term associated with an aggregate of dark matter (with the properties described in Paper I). Both have large pressure-like components which dominate the density terms. Using one form a simple model of the spiral galaxy halos is developed which can match the observed `flat' outer rotation curves of some galaxies,including the Milky Way. It can also represent the ascending outer rotational curves of small spiral galaxies such as M33. See Figs. 1, 2. The halo dark matter (DM)`missing mass' results from ignoring the pressure term's contribution to the source tensor. The analysis of the Milky Way rotation curve gives parameters characterizing the DM intergalactic medium in which the halo is situated.. The dark matter cannot come closer to the galactic center than $R \sim 4$ kpc. It reaches a maximum flux at $R_h \simeq 8$ kpc and then falls rapidly with distance. It is hoped that by analyzing other galactic rotation curves these models can be used to infer properties of the intergalactic DM matter. The other form for $T^{\mu \nu}$ for DM is useful in cosmology. Then a (non-constant) cosmological `constant' term $\Lambda$ needs to be added to Einstein's equation in order to allow use for DM of the standard equation of state relation of ordinary matter.. We suggest that at least some of the `dark energy' present results from this requirement and may not be real; it simply results from adopting an improper equation of state for DM.

4. A Model For Dark Matter Halos

Author

Helfer, H. L.

Abstract

A dark matter halo model is developed postulating a new state of matter, entities which have internal spin-like terms. Their motion in an external Schwarzschild metric is discussed. The internal spin motion contributes to the centrifugal force along with the usual orbital angular momentum term and can severely limit the distance of closest approach to the attractor. An energy-momentum tensor associated with an aggregate of them is shown to have primarily pressure-like components. A model of the spiral galaxy halos is developed which can match the observed `flat' rotation curves of some galaxies. The halo dark matter `missing mass' results from the pressure term's contribution to the metric tensor. A possible rationale for the presence of the cosmological constant is discussed. An addendum to the standard cosmology picture allows an estimate of the amount of dark matter; this is in reasonable agreement with that observed. It is possible that the adopted representation of the internal spin motion could be replaced by a boson string Lagrangian., Comment: 24 pages, 3 Appendices of 15 pages

11. Development of an elementary climate model: two-layer cellular case

Abstract

A qualitative understanding of the greenhouse effect has long been available through models based on globally- and time-averaged quantities. We examine here a simple 864-cell climatological model that emphasizes vertical radiative energy transport within each cell. It reproduces yearly average temperatures obtained earlier from one of these global models and predicts a locally distributed non-radiative flux when observed temperatures are employed as input data. Vertical and lateral transport of latent heat do not appear explicitly in this model. They are apparently handled well by one non-radiative flux variable, SNR, which shows a strong latitude dependence. Only the Sahara desert and Saudi Arabian regions appear to be complex. For those interested in climatology and construction of climate models, our model provides constraints upon specifying averaged non-radiative energy transport. The model is a useful simplification for learning about radiative energy transfer into and out of Earth?s atmosphere and for representing the results of more sophisticated models.

12. On the Interpretation Of the Local Dark Matter

Abstract

The cause of the extended rotation curves of galaxies is investigated. It is shown that conventional sources and most exotic sources for the needed gravitational fields are implausible. We suggest spatial fluctuations in a scalar field, similar to the inflation field, are responsible for the gravitational fields. These fluctuations play the role of `dark' halos around galaxies. They take $\sim 10^5$ yrs to develop and could not have been important in the early days of the universe. When galaxies are clustered, a $\Lambda-$term appears naturally in this theory. The universe's present energy density associated with these scalar field ariations is $\Omega \sim 1/2-2/3$. A possible scenario is uggested in which the cosmic scale factor ${\cal R}(t)$ would have experienced a recent acceleration. A discussion of further observations and theoretical work needed to resolve some ambiguities in the theory is given.

Abstract

Edoxaban is used for venous thromboembolism (VTE) treatment. Real-life data are lacking about its use in long-term therapy. We aimed to assess the efficacy and the safety of edoxaban for long-term VTE treatment in a real-life setting. Patients with VTE included in the Registro Informatizado Enfermedad TromboEmbólica (RIETE) registry, receiving edoxaban 60 or 30 mg daily were prospectively followed up to validate the benefit of using different dosages. The main outcome was the composite of VTE recurrences or major bleeding in patients with or without criteria for dose reduction. Multivariable analysis to identify predictors for the composite outcome was performed. From October 2015 to November 2019, 562 patients received edoxaban for long-term therapy. Most (94%) of the 416 patients not meeting criteria for dose reduction received 60 mg daily, and 92 patients meeting criteria (63%) received 30 mg daily. During treatment, two patients developed recurrent VTE, six had major bleeding and nine died (2 from fatal bleeding). Among patients not meeting criteria for dose reduction, those receiving 30 mg daily had a higher rate of the composite event (hazard ratio (HR) 8.37; 95% confidence interval (CI) 1.12–42.4) and a significant higher mortality rate (HR 31.1; 95% CI 4.63–262) than those receiving 60 mg. Among patients meeting criteria for dose reduction, those receiving 60 mg daily had no events, and a nonsignificantly higher mortality rate (HR 5.04; 95% CI 0.54–133) than those receiving 30 mg daily. In conclusion, edoxaban seems to be effective and safe for long-term VTE treatment in real life. Criteria for dose reduction should be reformulated., No funding was received for this work

Abstract

The association between elevated liver enzymes or FIB-4 (fibrosis index 4) and outcome in patients with venous thromboembolism (VTE) has not been evaluated. Data from patients in RIETE (Registro Informatizado Enfermedad TromboEmbólica) were used to assess the association between elevated liver enzymes or FIB-4 levels and the rates of major bleeding or death in apparent liver disease-free patients with acute VTE under anticoagulation therapy. A total of 6206 patients with acute VTE and without liver disease were included. Of them, 92 patients had major bleeding and 168 died under anticoagulation therapy. On multivariable analysis, patients with elevated liver enzymes were at increased mortality risk (HR: 1.58; 95% CI: 1.10–2.28), while those with FIB-4 levels > 2.67 points were at increased risk for major bleeding (HR: 1.69; 95% CI: 1.04–2.74). Evaluation of liver enzymes and FIB-4 index at baseline in liver disease-free patients with VTE may provide additional information on the risk for major bleeding or death during anticoagulation.

Abstract

Background Optimal risk stratification of unsuspected pulmonary embolism (UPE) in ambulatory cancer patients (ACPs) remains unclear. Existing clinical predictive rules (CPRs) are derived from retrospective databases and have limitations. The UPE registry is a prospective international registry with pre-specified characteristics of ACPs with a recent UPE. The aim of this study was to assess the utility of risk factors captured in the UPE registry in predicting proximate (30-, 90- and 180-day) mortality and how they performed when applied to an existing CPR. Objectives To evaluate risk factors for proximate mortality, overall survival, recurrent venous thromboembolism and major bleeding, in the patients enrolled in the UPE registry cohort. Methods Data from the 695 ACPs in this registry were subjected to multivariate logistic regression analyses to identify predictors independently associated with proximate mortality and overall survival. The most consistent predictors were applied to the Hull CPR, an existing 5-point prediction rule. Results The most consistent predictors of mortality were patient-reported respiratory symptoms within 14 days before, and ECOG performance status at the time of UPE. These predictors applied to the Hull-CPR produced a consistent correlation with proximate mortality and overall survival (area under the curve [AUC] = 0.70 [95% CI 0.63, 077], AUC = 0.65 [95% CI 0.60, 070], AUC = 0.64 [95% CI 0.59, 068], and AUC = 0.61, 95% CI 0.57, 0.65, respectively). Conclusion In ACPs with UPE, ECOG performance status logged contemporaneously to the UPE diagnosis and respiratory symptoms prior to UPE diagnosis can stratify mortality risk. When applied to the HULL-CPR these risk predictors confirmed the risk stratification clusters of low-intermediate and high-risk for proximate mortality as seen in the original derivation cohort.

Abstract

In the current era of patient empowerment and precision medicine, access to timely information is critical to decision-making. Unfortunately, we currently lack patient-specific, real-time data about clinical presentation, risk of thrombotic or hemorrhagic events, key risk factors, and adverse outcomes in patients with venous thromboembolism (VTE). Accordingly, the Registro Informatizado Enfermedad TromboEmbólica (RIETE) investigators developed a tool to provide an open-source, real-time graphic representation of VTE-related data derived from over 90 000 patients with confirmed VTE. This information is intended to facilitate discussion in the informed decision-making process. The current article describes the aims, rationale, methods, and ongoing and future efforts of the real-time VTE infographics developed by the RIETE registry collaborators.

Abstract

PURPOSE Pulmonary embolism is incidentally diagnosed in up to 5% of patients with cancer on routine imaging scans. The clinical relevance and optimal therapy for incidental pulmonary embolism, particularly distal clots, is unclear. The aim of the current study was to assess current treatment strategies and the long-term clinical outcomes of incidentally detected pulmonary embolism in patients with cancer. PATIENTS AND METHODS We conducted an international, prospective, observational cohort study between October 22, 2012, and December 31, 2017. Unselected adults with active cancer and a recent diagnosis of incidental pulmonary embolism were eligible. Outcomes were recurrent venous thromboembolism, major bleeding, and all-cause mortality during 12 months of follow-up. Outcome events were centrally adjudicated. RESULTS A total of 695 patients were included. Mean age was 66 years and 58% of patients were male. Most frequent cancer types were colorectal (21%) and lung cancer (15%). Anticoagulant therapy was initiated in 675 patients (97%), of whom 600 (89%) were treated with low-molecular-weight heparin. Recurrent venous thromboembolism occurred in 41 patients (12-month cumulative incidence, 6.0%; 95% CI, 4.4% to 8.1%), major bleeding in 39 patients (12-month cumulative incidence, 5.7%; 95% CI, 4.1% to 7.7%), and 283 patients died (12-month cumulative incidence, 43%; 95% CI, 39% to 46%). The 12-month incidence of recurrent venous thromboembolism was 6.4% in those with subsegmental pulmonary embolism compared with 6.0% in those with more proximal pulmonary embolism (subdistribution hazard ratio, 1.1; 95% CI, 0.37 to 2.9; P = .93). CONCLUSION In patients with cancer with incidental pulmonary embolism, risk of recurrent venous thromboembolism is significant despite anticoagulant treatment. Patients with subsegmental pulmonary embolism seemed to have a risk of recurrent venous thromboembolism comparable to that of patients with more proximal clots.

Abstract

BACKGROUND: Limited data exist about the clinical presentation, ideal therapy and outcomes of patients with hereditary hemorrhagic telangiectasia (HHT) who develop venous thromboembolism (VTE). METHODS: We used the data in the RIETE Registry to assess the clinical characteristics, therapeutic approaches and clinical outcomes during the course of anticoagulant therapy in patients with HHT according to initial presentation as pulmonary embolism (PE) or deep venous thrombosis (DVT). RESULTS: Of 51,375 patients with acute VTE enrolled in RIETE from February 2009 to January 2019, 23 (0.04%) had HHT: 14 (61%) initially presented with PE and 9 (39%) with DVT alone. Almost half (47.8%) of the patients with VTE had a risk factor for VTE. Most PE and DVT patients received low-molecular-weight heparin for initial (71 and 100%, respectively) and long-term therapy (54 and 67%, respectively). During anticoagulation for VTE, the rate of bleeding events (major 2, non-major 6) far outweighed the rate of VTE recurrences (recurrent DVT 1): 50.1 bleeds per 100 patient-years (95%CI: 21.6-98.7) vs. 6.26 recurrences (95%CI: 0.31-30.9; p = 0.020). One major and three non-major bleeding were epistaxis. No patient died of bleeding. One patient died shortly after being diagnosed with acute PE. CONCLUSIONS: During anticoagulation for VTE in HHT patients, there were more bleeding events than VTE recurrences. Most bleeding episodes were non-major epistaxis. ispartof: ORPHANET JOURNAL OF RARE DISEASES vol:14 issue:1 ispartof: location:England status: published

Abstract

Two forms are suggested for the energy-momentum source term associated with an aggregate of dark matter (with the properties described in Paper I). Both have large pressure-like components which dominate the density terms. Using one form a simple model of the spiral galaxy halos is developed which can match the observed `flat' outer rotation curves of some galaxies,including the Milky Way. It can also represent the ascending outer rotational curves of small spiral galaxies such as M33. See Figs. 1, 2. The halo dark matter (DM)`missing mass' results from ignoring the pressure term's contribution to the source tensor. The analysis of the Milky Way rotation curve gives parameters characterizing the DM intergalactic medium in which the halo is situated.. The dark matter cannot come closer to the galactic center than $R \sim 4$ kpc. It reaches a maximum flux at $R_h \simeq 8$ kpc and then falls rapidly with distance. It is hoped that by analyzing other galactic rotation curves these models can be used to infer properties of the intergalactic DM matter. The other form for $T^{����}$ for DM is useful in cosmology. Then a (non-constant) cosmological `constant' term $��$ needs to be added to Einstein's equation in order to allow use for DM of the standard equation of state relation of ordinary matter.. We suggest that at least some of the `dark energy' present results from this requirement and may not be real; it simply results from adopting an improper equation of state for DM.

Patients with autoimmune disorders are at an increased risk of venous thromboembolism (VTE), but this association has not been consistently evaluated. We used the RIETE (Registro Informatizado Enfermedad Trombo Embolica) database to compare the rates of VTE recurrences, major bleeding, and death during the course of anticoagulation, according to the presence or absence of autoimmune disorders. Of 71 625 patients with VTE recruited in February 2018, 1800 (2.5%) had autoimmune disorders. Median duration of anticoagulant therapy was slightly longer in patients with autoimmune disorders (median, 190 vs 182 days; P = .001). On multivariable analysis, patients with autoimmune disorders had a similar risk of VTE recurrences (hazard ratio [HR]: 0.93; 95% confidence interval [CI]: 0.68-1.27) or major bleeding (HR: 1.07; 95% CI: 0.82-1.40) and a lower risk to die (HR: 0.66; 95% CI: 0.54-0.81) than those without autoimmune disorders. Patients with giant cell arteritis had the highest rates of major bleeding (8.6 events per 100 patient-years) and the lowest rate of recurrences (zero). In other subgroups, the rates of both events were more balanced. During anticoagulation, patients with or without autoimmune disorders had similar rates of VTE recurrences or major bleeding. However, there were some differences between subgroups of patients with autoimmune disorders.

Abstract

BACKGROUND: The optimal cutoff for systolic blood pressure (SBP) level to define high-risk pulmonary embolism (PE) remains to be defined. METHODS: To evaluate the relationship between SBP levels on admission and mortality in patients with acute symptomatic PE, the current study included 39,257 consecutive patients with acute symptomatic PE from the RIETE registry between 2001 and 2018. Primary outcomes included all-cause and PE-specific 30-day mortality. Secondary outcomes included major bleeding and recurrent venous thromboembolism (VTE). RESULTS: There was a linear inverse relationship between admission SBP and 30-day all-cause and PE-related mortality that persisted after multivariable adjustment. Patients in the lower SBP strata had higher rates of all-cause death (reference: SBP 110-129 mmHg) (adjusted odds ratio [OR] 2.9; 95% confidence interval [CI], 2.0-4.2 for SBP 190 mmHg). Consistent findings were also observed for 30-day PE-related death. CONCLUSIONS: In patients with acute symptomatic PE, a low SBP portends an increased risk of all-cause and PE-related mortality. The highest mortality was observed in patients with SBP

Abstract

Background: The clinical outcomes during the course of anticoagulation in patients with venous thromboem-bolism (VTE) using statins remain controversial. Methods: We used the RIETE (Registro Informatizado Enfermedad TromboEmbolica) registry to compare the risk for VTE recurrences, major bleeding or death during anticoagulation, according to the use of statins at baseline. We used propensity score-matching (PSM) to adjust for confounding variables. Results: From February 2009 to January 2018, 32,062 VTE patients were included. Of these, 7,085 (22%) were using statins. Statin users were 10 years older (73 +/- 11 vs. 63 +/- 19 years, respectively) and more likely to have comorbidities or to be using antiplatelets or corticosteroids at baseline than non-users. During the course of anticoagulation (median, 177 days), 694 patients developed VTE recurrences, 848 bled and 3,169 died (fatal pulmonary embolism 176, fatal bleeding 121). Statin users had a similar rate of VTE recurrences (hazard ratio [HR]: 0.98; 95%CI: 0.82-1.17), a higher rate of major bleeding (HR: 1.29; 95%CI: 1.11-1.50) and a similar mortality rate (HR: 1.01; 95%CI: 0.93-1.10) than non-users. On PSM analysis, statin users had a significantly lower risk for death (HR: 0.62; 95%CI: 0.48-0.79) and a similar risk for VTE recurrences (HR: 0.98; 95%CI: 0.61-1.57) or major bleeding (HR: 0.85; 95%CI: 0.59-1.21) than non-users. Conclusions: During anticoagulation for VTE, patients using statins at baseline had a lower risk to die than nonusers.

Abstract

BackgroundCurrent guidelines suggest treating cancer patients with incidental pulmonary embolism (PE) similarly to those with clinically suspected and confirmed PE. However, the natural history of these presentations has not been thoroughly compared.MethodsWe used the data from the RIETE (Registro Informatizado de Enfermedad TromboEmbólica) registry to compare the 3-month outcomes in patients with active cancer and incidental PE versus those with clinically suspected and confirmed PE. The primary outcome was 90-day all-cause mortality. Secondary outcomes were PE-related mortality, symptomatic PE recurrences and major bleeding.ResultsFrom July 2012 to January 2019, 946 cancer patients with incidental asymptomatic PE and 2274 with clinically suspected and confirmed PE were enrolled. Most patients (95% versus 90%) received low-molecular-weight heparin therapy. During the first 90 days, 598 patients died, including 42 from PE. Patients with incidental PE had a lower all-cause mortality rate than those with suspected and confirmed PE (11% versus 22%; OR 0.43, 95% CI 0.34–0.54). Results were consistent for PE-related mortality (0.3% versus 1.7%; OR 0.18, 95% CI 0.06–0.59). Multivariable analysis confirmed that patients with incidental PE were at lower risk of death (adjusted OR 0.43, 95% CI 0.34–0.56). Overall, 29 (0.9%) patients developed symptomatic PE recurrences, and 122 (3.8%) had major bleeding. There were no significant differences in PE recurrences (OR 0.62, 95% CI 0.25–1.54) or major bleeding (OR 0.78, 95% CI 0.51–1.18).ConclusionsCancer patients with incidental PE had a lower mortality rate than those with clinically suspected and confirmed PE. Further studies are required to validate these findings, and to explore optimal management strategies in these patients.

Abstract

The dust jet model for production of narrow gamma-ray lines from SS 433 is examined and shown to be implausible. Sputtering rates at disk temperatures are high, and self-absorption rates in the disk and jet are important; both imply that dust particles would easily be destroyed. The energy deposited in the dust jet particles by collisions with the ambient protons should be radiated in the optical and infrared in amounts greatly exceeding that observed. The dust momentum pumps ambient gas out of the beam at rates which imply that for the steady state, the ambient gas has to have an initial temperature exceeding one million K. The ambient medium is also required to have densities exceeding those postulated for the H-alpha-emitting gas jet, and the interaction within the gas jet material would result in appreciable broadening of the H-alpha emission lines. At present, there is no viable model for the steady state production of the gamma-ray line radiation.

Abstract

Multiwavelength observations of the inner core of the M8 Hourglass region are presented, including VLA interferometric maps, 2-4 micron and 8-13 micron spectroscopy, photometric mapping in the K (2.2 micron) and L (3.45 micron) bands and in the 3.28 micron dust-emission feature, optical CCD imaging, and optical and infrared polarimetry. The compact H II region is excited by the O7 V star Herschel 36, and its apparent bipolar structure at optical wavelengths may be due to variable line-of-sight extinction and scattered light. Standard reddening laws are not applicable in the Hourglass region. A power law extinction lambda exp -0.78 yields consistent agreement between ultraviolet, optical, and infrared extinction estimates and suggests that one component of the total grain distribution is on the average larger than that found in the interstellar medium. The spatial distribution of the 3.28 micron dust-emission feature shows that the feature emission is associated with the boundary layer in the H II region/molecular cloud interface. The observations favor models in which feature emission comes from small refractory grains rather than from fluorescence or thermal emission from volatile mantles.
