A gravidez é um período em que a mulher passa por várias modificações em seu corpo, mas também por mudanças psicológicas. No Brasil, existem poucos estudos científicos sobre a relação do procedimento de histerectomia, suas possíveis indicações, a técnica em si, suas complicações e outros dados que poderiam auxiliar na melhoria desta prática no país. Ela é indicada para quadros clínicos típicos de problemas no útero como excesso de sangramento, dores e outros que não estão respondendo ao tratamento medicamentoso. Em outros casos como os miomas uterinos, dores pélvicas, infecções, prolapso de órgão pélvico, além do sangramento uterino anormal, câncer, este procedimento também é indicado. Ressalta-se ainda que o estudo teve caráter descritivo no qual utilizou a metodologia do tipo qualitativa, caracterizando-se, portanto, como um trabalho científico com foco no referencial teórico. Ao término do estudo tem-se a concepção de que realmente se fazem presentes as mudanças de comportamento das mulheres submetidas à histerectomia logo após o parto cesáreo, tais como traumas, medos, insegurança, ansiedade, sentimentos conflitivos, perda da motivação pelo ato sexual e outros que devem ser combatidos e prevenidos juntamente com o auxílio da equipe de Enfermagem e, se possível, o auxílio de outros profissionais para que essa insegurança desencadeada pelo fato da perda de um órgão seja superada.

A doença cárie é tida como um grande problema de saúde bucal em todo o mundo. Dessa forma, é caracterizada como uma doença comportamental diretamente ligada a hábitos alimentares, e a falta de higienização efetiva. A odontologia trabalha em busca de diminuir procedimentos invasivos, como as intervenções operatórias cuja intenção é favorecer um ambiente onde ocorra a paralisação da atividade cariogênica. Portanto, a remoção parcial do tecido cariado é considerada uma ótima opção quando a ideia é um tratamento que visa reabilitação estética e funcional do paciente, atrelado a promoção de saúde bucal1. E é um procedimento realizado de forma menos invasiva e com menos estresse ao paciente odontopediátrico. O objetivo desse trabalho é realizar uma revisão de literatura, tendo como a finalidade de se ampliar o conhecimento á respeito da remoção seletiva do tecido cariado em dentes decíduos e sobre a utilização da técnica de coroa metálica de hall technique. Tratamentos minimamente invasivos que removem o tecido cariado infectado, preservando tecidos afetados, e utilizam materiais de alta viscosidade com liberação de flúor como o cimento de ionômero de vidro tem demonstrado bons resultados na manutenção e prevenção da progressão da cárie dentária.  O presente estudo se trata de uma revisão narrativa da literatura, que considera artigos de revisão, relato de caso clínico, monografias e capítulos de livros publicados nas bases de dados Medline, Lilacs, Scielo e Google Acadêmico.

A adolescência é uma fase do ser humano confusa, muito caracterizada por incertezas, modificações corporais e psicológicas e a vontade de descobrir o sexo mais rápido. Com isso pode-se admitir que todos os adolescentes que estão em fase de descobertas e em desenvolvimento da puberdade e isso indica cada vez mais o aumento de mães adolescentes no mundo. Assim, a gravidez na adolescência é um problema que precisa ser enfrentado com políticas públicas eficazes por parte dos governantes, para que não haja mais aumentos significativos nos índices de vulnerabilidade socioeconômica e cultural da desses indivíduos visto que os jovens já são desprovidos de assistência pública e familiar. Outro ponto importante é que os problemas sociais só aumentam os riscos dessa ocorrência, além disso, a pobreza, a crise familiar, a baixa escolaridade são problemas pertinentes enfrentados pelos adolescentes e seus filhos. Trata-se de um trabalho científico com metodologia descritiva e foco no método qualitativo no qual pretende-se esclarecer sobre a gravidez na adolescência tendo como foco a importância da educação em saúde. Deste modo, a fundamentação teórica do referido estudo será produzida embasada na leitura, interpretação de fontes bibliográficas disponíveis, como livros, jornais, revistas, sites que abordam a temática para melhor fundamentar suas ideias, conceitos e concepções. Ao término do estudo constatou-se que a gravidez na adolescência é um tema bastante relevante atualmente, não devemos ignorar que essa demanda é um problema social, e o assistente social como profissional que acolhe esse público, deve estar atento para as formas de atuação e prevenção. Dessa forma, a gravidez na adolescência é um desafio social que envolve a todos como o Estado, a família e a sociedade e não um problema exclusivo da adolescente. Neste sentido, torna-se fundamental a realização de pesquisas que levantem as especificidades do fenômeno da maternidade na adolescência e determinem um caminho a seguir para a elaboração de políticas públicas voltadas para esse setor.

The internet is a very effective resource for solving all problems in the present era. The world's population as a whole spends one-third of their time and money using the internet. People learn things from it in every aspect of life, including education, entertainment, communication, shopping, etc. In order to achieve this, consumers take use of websites and share comments or opinions about various goods, services, events, etc. based on their personal experiences. In this way, the input from those webs is composed into a sizable amount of textual data that can be investigated, assessed, and controlled for the decision-making process. Natural Language Processing (NLP) and the extraction of the key theme are both aspects of opinion mining (OM). It's crucial to get feedback on our ideas from people in the form of good, negative, and neutral remarks. Researchers are now presenting information in the form of summaries that will benefit a variety of people. Since the 1950s, the research community has generated automatic summaries, but there are two distinct types of automation: abstractive and extractive approaches. A brief summary of opinion mining's automation process approaches and summarization techniques is provided in this paper.

Published: May 2024

This cross-sectional study investigates the shifts in anxiety levels among Swedish employees throughout the Covid-19 pandemic, with data gathered in 2016, 2018, and 2020. Work-related anxiety was assessed through two metrics: General Work Anxiety (WA) and Work Performance Anxiety (WPA). Overall, there was a decline in both average WA and WPA over the five-year period. However, this trend did not apply uniformly across all social groups. Specifically, WA saw a significant decrease among older men, while it showed an increase among younger women. Additionally, the reduction in WPA was more pronounced among managers than employees during the pandemic. High-income individuals and those with advanced education levels also experienced a greater decrease in WPA. These findings underscore the role of employment conditions in shaping the impact that the pandemic might have had on workers’ mental health.

The aim of integrated reporting is to provide a holistic view of an organization’s performance and value creation. This comprehensive reporting framework contains financial, economic, environmental, social, and governance aspects. In Malaysia, the adoption of integrated reporting shows the organization’s involvement in promoting accountability and transparency in corporate reporting. By using the Malaysian top 100 publicly listed companies (PLCs), this study gauges the practices of integrated reporting disclosure, explicitly investigating the integration of the content elements recommended by the International Integrated Reporting Council (IIRC) Framework. The examination of the integrated reports of the sample of Malaysian PLCs is done via a content analysis approach. Sampling from 2018 – 2020 data, this study is beneficial to contribute to the current body of literature on integrated reporting by shedding light on the ongoing practices of PLCs in Malaysia. This study has implications not only in advancing knowledge but also increases reporting practices within business and economics environments. Additionally, it adds valuable insights to the ongoing discussions surrounding corporate transparency and accountability. Furthermore, the study will present recommendations for enhancing the content of integrated reports, ultimately strengthening the reliability and utility of the disclosed information. These recommendations can be used by regulators, standard-setting bodies, and companies to further develop and refine integrated reporting practices in Malaysia.
Spin and charge interactions between nanographene host and ferrocene
Authors: Suzuki Akira , Miyake Yuya , Shibata Ryoga , Takai Kazuyuki
Published: May 2024

Ferrocene (FeCp2) was introduced as a non-magnetic guest molecule to activated carbon fibers (ACFs) as a nanographene-based host having localized spins originating from zigzag edges of graphene. The introduction of the guest molecule was confirmed by FTIR for ACFs-FeCp2 introduced at 55 (150) °C (FeCp2-ACFs-55(150)). The appearance of satellite Fe2p peaks and the increase in shake-up peak intensity of the C1s in the XPS spectrum proved the emergence of charge-transfer host–guest interaction in FeCp2-ACFs-150, supported by the red-shift of the G-band in the Raman spectrum. The six-times enhancement in the spin concentration in FeCp2-ACFs-150 compared with ACFs indicates the spin magnetism of the non-magnetic guest FeCp2+ molecule induced by a charge-transfer host–guest interaction in the nanographene host. The larger ESR linewidth than that expected from the dipolar interaction estimated by the localized spin concentration suggests the exchange interaction between the nanographene and FeCp2 spins. The narrowing of the ESR linewidth of FeCp2-ACFs-55 upon higher excitation microwave power suggests the inhomogeneity of the environment for FeCp2+ molecules in the nanographene host. The observed induction of spin magnetism by the interfacial interactions between the nanographene host and the guest molecules will be a promising strategy for developing a new class of molecular magnets.

Managing venous thrombosis in neonates poses numerous difficulties. Thrombotic events, whether arterial or venous, in newborns, can lead to significant morbidity and mortality within the hospitalized infant population. Neonates represent the age group with the highest susceptibility to developing thrombosis among pediatric patients. The evolving coagulation system, the necessity for intensive care, which often involves invasive procedures, and the presence of coexisting medical conditions collectively render neonates more prone to developing thrombosis compared to older children. Neonatal thrombosis is intertwined with the well-being of the mother and the newborn. We report a case of a very preterm newborn (30 weeks of gestation), extremely low birth weight (900g), with a multitude of prematurity related complications, who developed venous thrombosis at 5 weeks of life. She underwent prolonged hospitalization in the NICU, required mechanical ventilation, received nutritional and metabolic support via a central venous catheter, and complex treatments for sepsis with Staphylococcus CoNS. Genetic and hematology consults raised questions about the genetic basis of the thrombosis pathology, specifically thrombophilia or a RASopathy (Phenotype Noonan-like Syndrome). The prompt identification of risk factors leads to early therapeutic intervention, and multidisciplinary assessments are necessary to manage it. Conclusions. Neonatal thrombosis is impacted by many risk factors, encompassing genetic predispositions and perinatal complications. Notably, the NICU's environment is pivotal. Extended periods of immobility, invasive procedures, and the utilization of medical devices such as central venous catheters heighten the vulnerability to thrombosis in these fragile patients.

Endocrine disorders in the neonate, even if rare, could lead, if undetected, to preventable death or lifelong neurological consequences. This paper reviews special situations when the neonatologist should investigate a possible endocrine deficiency. We discuss three possible scenarios: the neonate with dysmorphic features or malformations that suggest a syndrome associated with endocrine deficiency (usually of the pituitary gland or hypothalamic-pituitary axis), the infant with positive screening test (usually a positive screening test when investigations and treatment are urgent. Special attention is given to the trickiest situation when an endocrine disease could occur: an unusual presentation of a normal neonatal condition. Two situations are discussed: prolonged jaundice, in which hypothyroidism or ACTH deficiency should be investigated, and persistent and prolonged hypoglycemia when congenital hyperinsulinism could be the cause. We provide clues to the diagnosis and treatment of this condition. As a take-home message for the neonatologist, endocrine disorders are conditions that should be known and promptly recognized, especially in the case of unusual presentations of different neonatal pathologies.

The Digitization of Photographic Spectra in the Dominion Astrophysical Observatory Plate Collection with Commercial Scanners: A Pilot Study
Authors: Davidge T. J.
Published: May 2024

Commercial flatbed scanners have the potential to deliver a quick and efficient means of capturing the scientific content of spectra recorded on photographic plates. We discuss the digitization of selected spectra in the Dominion Astrophysical Observatory (DAO) photographic plate collection with commercial scanners. In this pilot study, emphasis is placed on assessing if the information on the plates can be recovered using Epson V800 and 12000XL scanners; the more complicated issues associated with the shortcomings of photographic materials, such as correcting for nonlinearity, are deferred to a future study. Spectra of Vega (α Lyr) that were recorded over ∼4 decades with the DAO 1.8 m telescope are examined. These spectra sample a range of photographic emulsions, plate preparation techniques, calibration information, observing techniques, and spectrograph configuration. A scanning density of 2400 elements per inch recovers information in the spectra. Differences in the modulation transfer function (MTF) of the two scanners are found, with the Epson 12000XL having a superior MTF. Comparisons with a CCD spectrum of Vega confirm that moderately weak features are faithfully recovered in photographic spectra that have been digitized with the 12000XL scanner. The importance of scanning the full plate to cover the light profile of the target and calibration information is emphasized. Lessons learned from these experiments are also presented.
ethraid: A Simple Method for Characterizing Long-period Companions Using Doppler, Astrometric, and Imaging Constraints
Authors: Van Zandt Judah , Petigura Erik A
Published: May 2024

We present ethraid, an open-source Python package designed to measure the mass (m

c
) and separation (a) of a bound companion from measurements covering a fraction of the orbital period. ethraid constrains m

c
and a by jointly modeling radial velocity, astrometric, and/or direct imaging data in a Bayesian framework. Partial orbit data sets, especially those with highly limited phase coverage, are represented well by a few method-specific summary statistics. By modeling these statistics rather than the original data, ethraid optimizes computational efficiency with minimal reduction in accuracy. ethraid uses importance sampling to efficiently explore the often broad posteriors that arise from partial orbits. The core computations of ethraid are implemented in Cython for speed. We validate ethraid's performance by using it to constrain the masses and separations of the planetary companions to HD 117207 and TOI-1694. We designed ethraid to be both fast and simple, as well as to give broad, “quick look” constraints on companion parameters using minimal data. ethraid is pip installable and available on Zenodo and GitHub.
A Comparative Study of TESS Light-curve Extraction Methods Applied to Blazars

Blazars are characterized by largely aperiodic variability on timescales ranging from minutes to decades across the electromagnetic spectrum. The Transiting Exoplanet Survey Satellite (TESS) mission provides continuous sampling of blazar variability on timescales ranging from tens of minutes to 27 days for a single sector observation. Proper removal of the background, thermal ramping, and onboard systematic effects are crucial to the extraction of a reliable blazar light curve. Multiple publicly available procedures have been created to correct for these effects. Using ground-based observations from the Zwicky Transit Facility (ZTF) and the Asteroid Terrestrial-impact Last Alert System (ATLAS) as “ground truth” observations, we compare six different methods (regression, cotrending basis vectors, pixel-level decorrelation, eleanor, quaver, and simple differential photometry) to each other, and to our “ground truth” observations, to identify which methods properly correct light curves of a sample of 11 bright blazars, including the suspected neutrino source TXS 0506+056. In addition to comparing the resulting light curves, we compare the slopes of the power spectral densities, perform least-square fitting to simultaneous ZTF data, and quantify other statistical qualities generated from the light curves of each method. We find that only three of the six methods compared (simple differential photometry, eleanor, and quaver) produce TESS light curves consistent with the ground-based ZTF and ATLAS observations.

Measuring the relation between star formation and galactic winds is observationally difficult. In this work we make an indirect measurement of the mass-loading factor (the ratio between the mass outflow rate and star formation rate) in low-mass galaxies using a differential approach to modeling the low-redshift evolution of the star-forming main sequence and mass–metallicity relation. We use Satellites Around Galactic Analogs (SAGA) background galaxies, i.e., spectra observed by the SAGA Survey that are not associated with the main SAGA host galaxies, to construct a sample of 11,925 spectroscopically confirmed low-mass galaxies from 0.01 ≲ z ≤ 0.21 and measure auroral line metallicities for 120 galaxies. The crux of the method is to use the lowest-redshift galaxies as the boundary condition of our model, and to infer a mass-loading factor for the sample by comparing the expected evolution of the low-redshift reference sample in stellar mass, gas-phase metallicity, and star formation rate against the observed properties of the sample at higher redshift. We infer a mass-loading factor of

, which is in line with direct measurements of the mass-loading factor from the literature despite the drastically different sets of assumptions needed for each approach. While our estimate of the mass-loading factor is in good agreement with recent galaxy simulations that focus on resolving the dynamics of the interstellar medium, it is smaller by over an order of magnitude than the mass-loading factor produced by many contemporary cosmological simulations.
Evolutionary Period Changes for 52 Cataclysmic Variables, and the Failure for the Most-fundamental Prediction of the Magnetic Braking Model
Authors: Schaefer Bradley E.
Published: May 2024

The evolution of cataclysmic variables (CVs) is driven by period changes (

P

̇

), for which the long-venerable consensus is the magnetic braking model (MBM). The MBM has its only distinctive assumption being a power-law “recipe” describing the angular momentum loss (AML) in the binary, producing a single unique evolutionary track with

P

̇

as a function of the orbital period. This required prediction can be used to test the most-fundamental assumption of MBM, but it has never been tested previously. In this paper, I collect

P

measures for 52 CVs of all types. First, 44% of the CVs have positive

, with such being impossible in MBM. Second, even among the CVs with negative

P

̇

, their

P

̇

measures are always more negative than required by MBM, with an average deviation of 110×. Third, three CVs have large chaotic variations in

P

̇

that are impossible for MBM, proving that some unknown mechanism exists and is operating that dominates for these systems. Fourth, the MBM does not account for the long-term effects on evolution arising from the large sudden period decreases seen across many nova events, with this unaccounted effect dominating for the majority of nova systems and changing the sign of the overall evolutionary

P

. Fifth, three recurrent novae are observed to suddenly change

P

̇

by an order of magnitude across a nova event, with this being impossible in the MBM. In all, the required MBM

predictions all fail for my 52 CVs, usually by orders of magnitude, so the MBM AML-recipe is wrong by orders of magnitude.
Radial Spectral Evolution of the Elsässer Variable z

The nature of the Elsässer variable
z

− plays a significant role in the understanding of solar wind turbulence. The radial spectral evolution of
z

− observed by the Helios spacecraft suggests that
z

− has a persistent background spectrum in the low-frequency range from 0.3 to 1 au. However, the radial evolution in the near-Sun solar wind remains unknown. Here we use Parker Solar Probe measurements to analyze the averaged spectra of
z

− in the slow solar wind from 0.1 to 0.5 au and compare the results with the WIND observations at 1 au. We find that the averaged spectra of
z

− do not show the low-frequency break at the low-frequency breakpoint on the power spectra of
z

+, magnetic field, and velocity. The energy in the frequency range of 10−4–10−2 Hz demonstrates a radial decay from 0.1 to 0.5 au and keeps nearly constant to 1 au. The spectral index of
z

− gradually decreases from −1.27 at 0.1–0.2 au to −1.59 at 0.4–0.5 au and then slowly declines to −1.70 at 1 au. The radial behaviors of the ∥, ⊥1, and ⊥2 components of
z

− in the field-aligned coordinates are similar to that of the trace of
z

−. Our findings suggest a faster radial spectral evolution of
z

− in the near-Sun solar wind and provide strong observational constraints for the solar wind turbulence model.
Latest Evolution of the X-Ray Remnant of SN 1987A: Beyond the Inner Ring

Based on our Chandra imaging-spectroscopic observations, we present the latest evolution of the X-ray remnant of SN 1987A. Recent changes in the electron temperatures and volume emission measures suggest that the blast wave in SN 1987A is moving out of the dense inner ring structure, also called the equatorial ring (ER). The 0.5–2.0 keV X-ray light curve shows a linearly declining trend (by ∼4.5% yr−1) between 2016 and 2020 as the blast wave heats the hitherto unknown circumstellar medium (CSM) outside the ER. While the peak X-ray emission in the latest 0.3–8.0 keV image is still within the ER, the radial expansion rate in the 3.0–8.0 keV images suggests an increasing contribution of the X-ray emission from less dense CSM since 2012, at least partly from beyond the ER. It is remarkable that, since 2020, the declining soft X-ray flux has stabilized around ∼7 × 10−12 erg s−1 cm−2, which may signal a contribution from the reverse-shocked outer layers of ejecta as predicted by the three-dimensional magnetohydrodynamic models. In the latest ACIS spectrum of supernova remnant 1987A in 2022 we report a significant detection of the Fe K line at ∼6.7 keV, which may be due to changing thermal conditions of the X-ray emitting CSM and/or the onset of reverse shock interactions with the Fe ejecta.

We have studied the stability of C59 anions as a function of time, from their formation on femtosecond timescales to their stabilization on second timescales and beyond, using a combination of theory and experiments. The

fragments were produced in collisions between C60 fullerene anions and neutral helium gas at a velocity of 90 km s−1 (corresponding to a collision energy of 166 eV in the center-of-mass frame). The fragments were then stored in a cryogenic ion beam storage ring at the DESIREE facility, where they were followed for up to 1 minute. Classical molecular dynamics simulations were used to determine the reaction cross section and the excitation energy distributions of the products formed in these collisions. We find that about 15% of the

C

ions initially stored in the ring are intact after about 100 ms and that this population then remains intact indefinitely. This means that C60 fullerenes exposed to energetic atoms and ions, such as stellar winds and shock waves, will produce stable, highly reactive products, like C59, that are fed into interstellar chemical reaction networks.
