Authors: Guevara-Ríos Enrique 
Published: August 2019

La preeclampsia es un desorden del embarazo asociado con el inicio de hipertensión después de las 20 semanas, con o sin proteinuria, y con la presencia o no, de una gran variedad de síntomas como dolor en cuadrante superior derecho del abdomen, cefalea1. Es una enfermedad de carácter irreversible que afecta múltiples órganos y, debido a que lesiona a la madre y al feto, es responsable de una proporción considerable de muertes maternas y perinatales.
Según la Organización Mundial de la Salud, la preeclampsia es la segunda causa de muerte en el mundo con un 14% 2; y en el Perú en el I semestre del 2018 fue la primera causa de muerte materna con un 28,7% 3.
En el Instituto Nacional Materno Perinatal entre el 2007 y el 2018 se produjeron 97 casos de muerte materna, y la preeclampsia fue la primera causa con un 44,3% 4. Asimismo entre el 2012 y el 2018 se atendieron en el instituto un total de 1870 casos de morbilidad materna extrema, siendo la principal causa los transtornos hipertensivos del embarazo con el 56,6% (164 casos) entre preeclampsia con criterios de severidad, síndrome HELLP y eclampsia 4.
Por lo tanto la preeclampsia siendo un problema de una gran magnitud y una gran repercusión social, debe ser considerada como un problema de salud pública. Por esta razón, entre el 2016 y el 2017, el Instituto Nacional Materno Perinatal, conjuntamente con el Instituto Nacional de Salud, Hospital San Bartolomé, Red de Salud San Juan de Lurigancho y ESSALUD, y con el apoyo de la Organización Panamericana de Salud y la Universidad McMaster de Canadá, elaboró una Guía de Práctica Clínica para la prevención y manejo de la preeclampsia, con el objetivo de estandarizar los criterios clínicos basados en evidencia científica disponible siguiendo la metodología AGREE II y Grade5.

Published: August 2019

Background: Schizophrenia is a mental disorder with a high incidence and relapse due to a lack of family support. Families do not understand how to treat patients with schizophrenia. There are several factors related to the family’s abilities in treating patients with schizophrenia, there are the level of family’s knowledge, perception, and burden.
Objective: This study aimed to describe the knowledge, perception and burden of family in treating patients with schizophrenia who experience a relapse.
Methods: The research used descriptive quantitative method. Samples were selected by consecutive sampling technique and obtained 100 respondents. Data were collected by a questionnaire consisting of family knowledge and perception developed by the researcher, and Zarit Burden Interview scale was used to measure the family burden. Data were analyzed using percentages, score T, and the Zarit Burden Interview analysis.
Results: Findings showed that 31 respondents (31%) had good knowledge, 42 respondents (42%) had sufficient knowledge, and 27 respondents (27%) had insufficient knowledge. In terms of perception, 66 respondents (66%) had a positive perception and 33% had a negative perception. In addition, 42 respondents (42%) had moderate to heavy burden levels, 23 respondents (23%) had a very heavy level of heavy burden, and 3 respondents (3%) with very heavy levels of burden.
Conclusions: Based on the results, it is necessary to increase the frequency of health education for the families. In addition, it is also important to hold a sharing program between families to reduce family burden.

Authors: Anh Le Hieu Thuy , Thaweesit Suchada 
Published: August 2019

Background: Human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) are the leading causes of death from infectious diseases. Because of sharing same transmission routes, the co-infection of HIV with HBV or HCV is common. And the co-infections make HIV infected persons have higher morbidity and mortality than those who infected only with HIV. This study aims to investigate factors that may have influence on the co-infections of HBV or HCV among HIV positive individuals.
Objective: The goals of this study were to identify factors associated with the co-infection of HBV or HCV among people living with HIV.
Methods: Quantitative research method was applied in this study to examine factors associated with HBV or HCV co-infection among HIV infected people. A total of 250 HIV infected individuals in Khanh Hoa province, Vietnam were the sample of this study. It employed the Social Ecological Model (SEM) as a theoretical perspective that focused on multiple levels of factors. Descriptive statistic was used to describe the general characteristics of the respondents. And Binary logistic regression was carried out to measure the influence of factors on the co-infection.
Results: The multivariate analysis of this study showed that HIV-HBV co-infection was associated significantly with residents of Nha Trang (OR= 7.179). Regarding HIV-HCV co-infection, being men (OR= 7.617), unemployed (OR= 4.013), a resident of Nha Trang (OR=10.894) and an injecting drug user (OR= 16.688) were risk factors of the co-infection.
Conclusions: This study recommended that intervention strategies to prevent HIV-positive individuals from co-infection with either HBV or HCV should focus on altering individuals’ risk behaviors and their socio-economic environments. Also, specific preventing programs should be implemented and focus on unemployed populations, injecting drug users, men in general, as well as people living in particular areas, especially cities having a large number of people living with HIV.

A Superluminous Supernova in High Surface Density Molecular Gas within the Bar of a Metal-rich Galaxy

Abstract
We report the Atacama Large Millimeter/submillimeter Array observations of the metal-rich host galaxy of superluminous supernova (SLSN) PTF10tpz, a barred spiral galaxy at z = 0.03994. We find the CO(1–0) emission to be confined within the bar of the galaxy. The distribution and kinematics of molecular gas in the host galaxy resemble gas flows along two lanes running from the tips of the bar toward the galaxy center. These gas lanes end in a gaseous structure in the inner region of the galaxy, likely associated with an inner Lindblad resonance. The interaction between the large-scale gas flows in the bar and the gas in the inner region plausibly leads to the formation of massive molecular clouds and consequently massive clusters. This in turn can result in formation of massive stars, and thus the likely progenitor of the SLSN in a young, massive cluster. This picture is consistent with SLSN PTF10tpz being located near the intersection regions of the gas lanes and the inner structure. It is also supported by the high molecular gas surface densities that we find in the vicinity of the SLSN, surface densities that are comparable with those in interacting galaxies or starburst regions in nearby galaxies. Our findings therefore suggest in situ formation of massive stars due to the internal dynamics of the host galaxy and also lend support to high densities being favorable conditions for formation of SLSN progenitors.

Published: August 2019

Abstract
We report X-ray data analysis results obtained from Chandra, XMM-Newton, Nuclear Spectroscopic Telescope Array Mission (NuSTAR), and Swift observations of PSR J2032+4127 taken before, during, and after the periastron on 2017 November 13. We found the first clear evidence of a change in the X-ray spectral index over the passage period, thanks to a broad and sensitive spectral coverage by XMM-Newton and NuSTAR. We analyzed the joint XMM-Newton and NuSTAR observation epochs with power-law and broken power-law models. We have obtained changes in spectral parameters before and after the periastron passage for both models. The spectra get softened after the passage. The evolution of the spectral index and break energy before and after the periastron may indicate a change in the physical state of shock-accelerated electrons.
The Impact of White Dwarf Natal Kicks and Stellar Flybys on the Rates of Type Ia Supernovae in Triple-star Systems
Authors: Hamers Adrian S. , Thompson Todd A. 
Published: August 2019

Abstract
SNe Ia could arise from mergers of carbon–oxygen white dwarfs (WDs) triggered by Lidov–Kozai (LK) oscillations in hierarchical triple-star systems. However, predicted merger rates are several orders of magnitude lower than the observed SNe Ia rate. The low predicted rates can be attributed in part to the fact that many potential WD-merger progenitor systems, with high mutual orbital inclination, merge or interact before the WD stage. Recently, evidence was found for the existence of natal kicks imparted on WDs with a typical magnitude of 0.75 km s−1. In triples, kicks change the mutual inclination and in general increase the outer orbit eccentricity, bringing the triple into an active LK regime at late stages and avoiding the issue of pre-WD merger or interaction. Stars passing by the triple can result in similar effects. However, both processes can also disrupt the triple. In this paper, we quantitatively investigate the impact of WD kicks and flybys on the rate of WD mergers using detailed simulations. We find that WD kicks and flybys combine to increase the predicted WD merger rates by a factor of ∼2.5, resulting in a time-integrated rate of ≈1.1 × 10−4

Implications of Symmetry and Pressure in Friedmann Cosmology. I. Formalism
Authors: Croker K. S. , Weiner J. L. 
Published: August 2019

Abstract
We show that derivation of Friedmann’s equations from the Einstein–Hilbert action, paying attention to the requirements of isotropy and homogeneity during the variation, leads to a different interpretation of pressure than what is typically adopted. Our derivation follows if we assume that the unapproximated metric and Einstein tensor have convergent perturbation series representations on a sufficiently large Robertson–Walker coordinate patch. We find the source necessarily averages all pressures, everywhere, including the interiors of compact objects. We demonstrate that our considerations apply (on appropriately restricted spacetime domains) to the Kerr solution, the Schwarzschild constant-density sphere, and the static de-Sitter sphere. From conservation of stress–energy, it follows that material contributing to the averaged pressure must shift locally in energy. We show that these cosmological energy shifts are entirely negligible for non-relativistic material. In relativistic material, however, the effect can be significant. We comment on the implications of this study for the dark energy problem.
Thermal Infrared Imaging of MWC 758 with the Large Binocular Telescope: Planetary-driven Spiral Arms?
Authors: Wagner Kevin , Stone Jordan M. , Spalding Eckhart , Apai Daniel , Dong Ruobing , Ertel Steve , Leisenring Jarron , Webster Ryan 
Published: August 2019

Abstract
Theoretical studies suggest that a giant planet around the young star MWC 758 could be responsible for driving the spiral features in its circumstellar disk. Here, we present a deep imaging campaign with the Large Binocular Telescope with the primary goal of imaging the predicted planet. We present images of the disk in two epochs in the L′ filter (3.8 μm) and a third epoch in the M′ filter (4.8 μm). The two prominent spiral arms are detected in each observation, which constitute the first images of the disk at M′, and the deepest yet in L′ (ΔL′ = 12.1 exterior to the disk at 5σ significance). We report the detection of an S/N ∼ 3.9 source near the end of the Southern arm, and, from the source’s detection at a consistent position and brightness during multiple epochs, we establish a ∼90% confidence-level that the source is of astrophysical origin. We discuss the possibilities that this feature may be (a) an unresolved disk feature, and (b) a giant planet responsible for the spiral arms, with several arguments pointing in favor of the latter scenario. We present additional detection limits on companions exterior to the spiral arms, which suggest that a ≲4 M
Jup planet exterior to the spiral arms could have escaped detection. Finally, we do not detect the companion candidate interior to the spiral arms reported recently by Reggiani et al., although forward modeling suggests that such a source would have likely been detected.
X-Ray and Gamma-Ray Emission from Core-collapse Supernovae: Comparison of Three-dimensional Neutrino-driven Explosions with SN 1987A

Published: August 2019

Abstract
During the first few hundred days after the explosion, core-collapse supernovae (SNe) emit down-scattered X-rays and gamma-rays originating from radioactive line emissions, primarily from the 56Ni → 56Co → 56Fe chain. We use supernova (SN) models based on three-dimensional neutrino-driven explosion simulations of single stars and mergers to compute this emission and compare the predictions with observations of SN 1987A. A number of models are clearly excluded, showing that high-energy emission is a powerful way of discriminating between models. The best models are almost consistent with the observations, but differences that cannot be matched by a suitable choice of viewing angle are evident. Therefore, our self-consistent models suggest that neutrino-driven explosions are able to produce, in principle, sufficient mixing, although remaining discrepancies may require small changes to the progenitor structures. The soft X-ray cutoff is primarily determined by the metallicity of the progenitor envelope. The main effect of asymmetries is to vary the flux level by a factor of ∼3. For the more asymmetric models, the shapes of the light curves also change. In addition to the models of SN 1987A, we investigate two models of SNe II-P and one model of a stripped-envelope SN IIb. The Type II-P models have observables similar to those of the models of SN 1987A, but the stripped-envelope SN model is significantly more luminous and evolves faster. Finally, we make simple predictions for future observations of nearby SNe.

Abstract
Chronic neuroinflammation is a key pathological hallmark of multiple sclerosis (MS) that suggests that resolution of inflammation by specialized proresolving molecules is dysregulated in the disease. Annexin A1 (ANXA1) is a protein induced by glucocorticoids that facilitates resolution of inflammation through several mechanisms that include an inhibition of leukocyte recruitment and activation. In this study, we investigated the ability of ANXA1 to influence T cell effector function in relapsing/remitting MS (RRMS), an autoimmune disease sustained by proinflammatory Th1/Th17 cells. Circulating expression levels of ANXA1 in naive-to-treatment RRMS subjects inversely correlated with disease score and progression. At the cellular level, there was an impaired ANXA1 production by CD4+CD25− conventional T and CD4+RORγt+ T (Th17) cells from RRMS subjects that associated with an increased migratory capacity in an in vitro model of blood brain barrier. Mechanistically, ANXA1 impaired monocyte maturation secondarily to STAT3 hyperactivation and potently reduced T cell activation, proliferation, and glycolysis. Together, these findings identify impaired disease resolution pathways in RRMS caused by dysregulated ANXA1 expression that could represent new potential therapeutic targets in RRMS.
