Este artigo tem por objetivo analisar os fatores de risco associados à trombose venosa profunda em pacientes de alto risco e propor estratégias de prevenção que possam ser implementadas de forma eficaz no contexto clínico. Foram utilizados como motores de busca a base de dados Pubmed Science para seleção dos artigos, através dos unitermos “Trombose Venosa Profunda”, “Fatores de Risco”, “Prevenção’’. As considerações finais deste estudo destacam a relevância da identificação precoce e do manejo eficaz dos fatores de risco associados à trombose venosa profunda em pacientes de alto risco. A pesquisa evidenciou que comorbidades, imobilização prolongada e obesidade desempenham papéis críticos na incidência da TVP. Assim, a adoção de estratégias preventivas, como mobilização precoce, uso de meias de compressão e profilaxia farmacológica, é essencial para reduzir a ocorrência dessa condição. A educação contínua dos profissionais de saúde e dos pacientes sobre a importância dessas medidas é fundamental para a melhoria dos desfechos clínicos. Além disso, a necessidade de um acompanhamento regular e individualizado para pacientes em risco não pode ser subestimada. Programas que promovam a adoção de hábitos saudáveis e o manejo do peso devem ser integrados às práticas clínicas para abordar a obesidade como um fator de risco significativo. Em suma, uma abordagem multifatorial e colaborativa é crucial para efetivamente prevenir a trombose venosa profunda, melhorando assim a qualidade de vida dos pacientes e minimizando complicações associadas.

INTRODUÇÃO: A meningite é uma doença causada por diferentes agentes etiológicos e caracterizada por inflamação das meninges, cujos principais sintomas são febre, rigidez nucal, cefaléia, vômitos e fotofobia. Apresenta grande importância epidemiológica, apresentando elevada morbimortalidade em todas as faixas etárias. A vacinação continua sendo uma das principais formas de prevenção contra a doença no país. OBJETIVO: Analisar as taxas de incidência de meningite entre 2010 e 2019 comparando as diferentes séries históricas das cinco regiões brasileiras. METODOLOGIA: Trata-se de estudo observacional das séries temporais da taxa de incidência de meningite, estratificado por região brasileira, entre os anos de 2010 e 2019, com dados obtidos do Sistema de Informação de Agravos de Notificação, e estimativas populacionais a partir de dados do IBGE disponíveis no DataSUS. RESULTADOS: Entre 2010 e 2019, a maior taxa média de incidência foi na região Sul (12,5 casos/100 mil habitantes), seguida pelo Sudeste (11,7), Nordeste (5,6), Centro-Oeste (5,6) e Norte (4,5). A taxa média nacional foi de 9,1. A taxa de incidência de meningite apresentou tendência estacionária nas regiões Norte (p-valor 0,881) e Sul (p-valor 0,402), enquanto apresentou tendência decrescente nas regiões Nordeste (p-valor 0,008), Sudeste (p-valor 0,004), Centro-Oeste (p-valor <0,001). CONCLUSÃO: Houve redução da taxa de incidência de meningite em âmbito nacional, especialmente nas regiões Centro-Oeste, Sudeste e Nordeste. As maiores taxas regionais foram encontradas no Sul e Sudeste durante todo o período analisado. Apesar das melhores condições socioeconômicas dessas regiões, a alta concentração populacional nessas áreas é aspecto importante que deve ser levado em consideração.

Authors: Helou de Oliveira Luciano , Marques de Oliveira Hunder , Costa Barbosa Bruno
Published: October 2024

Este estudo realizou uma revisão integrativa da literatura para investigar os métodos de preservação da fertilidade em pacientes oncológicos. Foram incluídos estudos publicados entre 2015 e 2023, selecionados nas bases de dados PubMed, Scielo e Lilacs, utilizando descritores como "preservação da fertilidade" e "pacientes oncológicos". Os principais métodos identificados foram a criopreservação de óvulos, embriões, tecido ovariano e esperma, além do uso de análogos de GnRH para proteção da função ovariana durante a quimioterapia. A criopreservação de óvulos e embriões mostrou-se altamente eficaz, com taxas de sucesso variando de 30% a 60%, dependendo da idade da paciente e da qualidade dos gametas. A criopreservação de tecido ovariano, embora ainda experimental, mostrou resultados promissores na restauração da função ovariana. Nos homens, a criopreservação de esperma é amplamente utilizada, com altas taxas de sucesso. A educação dos pacientes sobre essas opções antes do tratamento oncológico é crucial. A revisão destaca a importância da preservação da fertilidade como parte integrante do cuidado oncológico, visando melhorar a qualidade de vida dos sobreviventes.

Effective indoor ventilation systems are crucial in reducing airborne viruses in healthcare facilities which include significant sections such as OR, isolation room and emergency department. Infection control through indoor ventilation system can be done by manipulating the concentration of infectious particles to reduce airborne infections. This review article highlighted different types of indoor ventilation strategies including mechanical ventilation system, natural ventilation system and hybrid ventilation system that have been integrated into different healthcare facilities. The overview, advantages, and limitations of each strategy were discussed in detail. The utilization of mechanical was deemed more suitable for better air quality control, while a vertical (ceiling-mounted) airflow ventilation system was found to promote higher air cleanliness in the desired zone in healthcare facilities. However, many ventilation systems face limitations when attempting to maintain both thermal comfort, indoor air quality, and energy efficiency simultaneously. The findings of this review are useful for the researchers who design appropriate ventilation strategies in healthcare facilities to ensure good indoor air quality meanwhile reduce the risk of disease dissemination.
Elucidation of gene action and estimation of combining ability effects for fruit yield attributes and biochemical traits in brinjal (Solanum melongena L.)
Authors: N. Dudhatra Kuldeep , P. Patel Mukesh , M. Pandya Mihir
Published: October 2024

Abstract The present investigation was undertaken in brinjal (Solanum melongena L.) to estimate combining ability and gene action following a half diallel mating design using ten parents. The ratio of genetic variance components, σ2gca/σ2sca and σ2D/σ2A, showed dominant gene action, indicating the presence of non-additive genetic variance for days to 50% flowering, fruit yield per plant, total phenol, antioxidant activity and total soluble sugar. The traits fruits per plant, fruit girth, and fruit weight showed additive genetic variance. Among the parental genotypes, AB 15-08, ABSR 2 and AB 20-13 were found to be good general combiners for fruit yield, fruits per plant, and total soluble solids. The three highest-ranking hybrids were AB 15-08 × AB 20-13, AB 15-08 × AB 20-03 and AB 20-07 × GP BRJ 224. The above hybrids would be rewarding for harnessing heterosis.

Published: October 2024

Abstract Yield, a multifaceted trait influenced by genetic and environmental factors, requires a comprehensive assessment beyond emphasizing only on yield alone. Thus, understanding the intricate relationship between yield and its associated traits across diverse chickpea genotypes is essential. The current investigation was undertaken at the Breeder seed production unit, JNKVV, Jabalpur, Madhya Pradesh, during the 2021-22 cropping season. Significant variations were found by analysis of variance (ANOVA) among the 40 genotypes under study, indicating substantial variability. Post hoc DMRT analysis further confirmed notable genetic diversity across all traits. Regression and Principal component analysis highlighted the significance of optimizing biological yield per plant, effective pods, total number of pods, and secondary branches to enhance grain yield. Strategic selection prioritizing these traits can facilitate the development of high-yielding chickpea varieties with enhanced agronomic characteristics. This analysis identified five principal components explaining 80.74% of genotypic variability. Ultimately, the genotypes ICCV 211210, RVG-204, and ICCV 211206 emerged as promising based on PC scores. Keywords: Chickpea, DMRT, Regression, PCA, Yield

Published: October 2024

Hybrid technology is exploited in kharif (rainy) sorghum while the same is not the scenario in Rabi sorghum which is still dominated by landraces and varieties which have poor yield potentiality. Considering the necessity of development of heterotic hybrids, an attempt was made to screen hybrid parents (B and R lines) to assess variability and genetic diversity, for productivity traits. The study was conducted with 32 B and R lines at Regional Agricultural Research Station, Vijayapur during 2021-22. PCV was observed to surpass GCV across all traits. The traits grain yield per plant, fodder yield per plant, grain number per plant, and harvest index exhibited notably high PCV and GCV. Plant height, panicle length, panicle harvest index, and harvest index recorded high heritability and genetic advance, suggesting their control by additive gene action and potential for improvement via selection. Cluster analysis classified the 32 genotypes into four groups. PCA condensed 14 traits into five principal components, capturing 81.50% of total variation. The genotypes remained scattered in all four quadrants in PCA- Biplot, showing large genetic variability in quantitative traits studied. Keywords: Genetic variability, heritability, diversity, clusters, PCA and rabi sorghum

Authors: D. Purushotama Rao , H. P. Chaturvedi
Published: October 2024

Foxtail millet is a main millets crop of Northeastern region of India. The genotype-by-environment analyses assist in understanding the potential performance of the genotypes over environments. The present study aimed to investigate the 30 foxtail genotypes over the four different environments to identify the genotypes with stable yield in this region. The investigation was carried out during July 2022 to May 2023 for four different dates of sowing with fifty-five days interval. Two environments maintained under rainfed condition and the remaining two environments are maintained under irrigated condition with seven days interval. The experiment was conducted in randomized complete block design with three replications in all environments. Genotype-environment interactions significantly influenced grain yield across four environments, while replicates were non-significant. Pooled analysis revealed significant genotypic effects and seasonal impacts. The “discriminating power vs. representativeness” GGE biplot showed that E4 (showing dates in January 2ndfort night) is the most ideal test environment for foxtail millet elite line selection based on discriminative ability and representativeness. The accessions that performed best in each environment based on “which-won-where” polygon biplot, genotypes G19 (FOX 4392) and G27 (FOX 4420) showed superior and stable performance in E1, however G25 (FOX 4341) and G1 (ELS 20) excelled in E2, E3, and E4.Mean vs stability biplots exposed G1 (ELS 20) is stable and high yielding performance. Ranking genotypes GGE biplot identify the G25 (FOX 4341) is an ideal genotype due to its higher yield and stability compared to the other genotypes.

Authors: Margam Bharath Kumar , Chakraborty Nihar Ranjan
Published: October 2024

Abstract Combining ability and heterosis was investigated in mustard hybrids obtained from 7 × 7 half diallel cross. Twenty one F1s along with seven parents were evaluated in Randomized Complete Block Design. The combined analysis of variance revealed very significant differences among the parents for all morphological variables with the exception of secondary branches and siliqua length, indicating wide diversity among the parental material used in the present study. Significant GCA and SCA variance indicated additive and non-additive gene action across all the characters. The SCA variance components were larger than the GCA variance components for most traits indicating the prevalence of non-additive gene effects. Jawahar mustard × PM-30, showed a significantly positive SCA and better parent heterosis for seed yield per plant whereas five hybrids (Kranti × PM-30, Gujarat Mustard-3 × Pusa Mahak, Jawahar Mustard × PM-30, Jawahar Mustard × Pusa Mahak and PM-30 × Pusa Mahak) exhibited significant positive SCA effect for number of siliqua/ plant. Jawahar Mustard × PM-30, Varuna×Jawahar Mustard, Gujarat Mustard-3 × PM-30, exhibited highly significant heterosis over the mid-parent. Keywords: Brassica juncea, GCA, SCA, gene action, Heterosis

St Lawrence, Alton, Hampshire: the Romanesque crossing and the origins of the Anglo-Saxon minster
Authors: Secker Daniel
Published: October 2024

The earliest architectural details of the church of St Lawrence, Alton are the Romanesque crossing arches which date from c.1095-1110. A survey of the crossing, however, suggests the arches were inserted into an earlier structure: a minster church indirectly implied in the grant of William I of the church at Alton to New Minster. The 1984 excavations at Amery House immediately south of the church revealed two ditches, one of probable 7th-century date, which may relate to a minster enclosure. This possibly succeeded an early Anglo-Saxon cemetery, though there is no evidence for direct continuity. Alton’s dependent chapel at Holybourne was axially aligned on springs which the place-name suggests were of ritual significance, but this was also a hundredal meeting place, the focus purveying both religious and political power.
Re-evaluating the landscape of early ecclesiastical foundation in the Kingdom of Lindsey
Authors: Willmott Hugh
Published: October 2024

In 1993, David Stocker published a review of the evidence for the early church in Lincolnshire, proposing a series of models explaining the pattern behind the documented foundations of the 7th and 8th centuries. Over the last three decades, excavations at West Halton, Partney, Little Carlton and the long-awaited publication of those from Flixborough, in addition to new research at a range of other sites, make a re-evaluation of his arguments possible. By focusing on the historical Kingdom of Lindsey, this paper revisits some of Stocker’s propositions, and in particular the notion of the close pairing of ecclesiastical and secular settlements. Further attention is drawn to the close connection between newly established churches and pre-existing ritual features, as exemplified by the recently excavated pre-Christian shrine at West Halton.

Authors: Ingram Jamie
Published: October 2024

This paper deals with the historic graffiti recorded between 2014 and 2015 at Chichester Cathedral and discusses some of the marks as well as the assemblage as a whole. The graffiti was analysed geospatially, and distribution patterns were identified. The distribution pattern suggests that regular deposition of graffiti was practiced at known points of veneration and may be connected to practices of worship. The graffiti may constitute a ritual doing as a part of the performative ritual conducted by lay worshippers within the Cathedral and in the presence of the shrine of St Richard and other places of veneration.

Charnel-associated burial and monuments in late medieval England: Henry Barton’s effigy and its afterlife at Old St Paul’s Cathedral
Authors: Farrow Thomas J.
Published: October 2024

In late medieval England, high-status individuals sometimes requested burial and/or memorialisation in association with charnel chapels, which primarily housed the exhumed and redeposited remains of the anonymous collective dead. The monument of Henry Barton (d.1435) in the charnel chapel at Old St Paul’s Cathedral, London, was one such memorial which held distinctive secular as well as religious resonance in context. In order to fully situate its significance, 40 examples of English cathedral, monastic, and parish charnel-associated burials and/or monuments will be identified and explored here for the first time. Their interrogation will furnish a broad understanding of this phenomenon’s meaning and motivation within the context of intercessory belief and mortuary practice in late medieval Catholic England. Further consideration of Barton’s monument will trace its revaluation following the 1547 dissolution of the chantries, which catalysed the widespread destruction of associated structures and material culture. While Barton’s effigy was subsequently destroyed in 1549, an ‘old worn stone’ bearing his name remained visible at the chapel site until c1666. Critical consideration of its form and survival will provide insight into the status of pre-Reformation monuments in the post-Reformation cathedral landscape, as well as the fate of the charnel chapel structure and site itself.
Investigating Nineteenth-Century change at Kirkliston Parish Church
Authors: Pickering Rachel
Published: October 2024

This article presents the results of an in-depth investigation of post-medieval Kirkliston parish church (Edinburgh), using an interdisciplinary buildings archaeology approach. Despite a wealth of existing scholarship on Scotland’s churches, the archaeological investigation of parish churches has been somewhat limited, and narratives tend to be predisposed towards the medieval. The 19th century in particular has rarely been engaged with in church archaeology, even though the period saw significant social and religious change, and transformational developments in church buildings. Visual and stratigraphic analysis, combined with comprehensive documentary research, uncovered new evidence and layers of meaning for three separate phases of change during the 19th century that fundamentally shaped the present church. The results demonstrate the strengths of an archaeological approach and highlight the value of studying all phases of a church’s development. At a time when many of Scotland’s churches face redundancy, closure, or dereliction, this research emphasizes their high archaeological value and research potential.

Published: October 2024

Event Horizon Telescope (EHT) images of the horizon-scale emission around the Galactic center supermassive black hole Sagittarius A* (Sgr A*) favor accretion flow models with a jet component. However, this jet has not been conclusively detected. Using the “best-bet” models of Sgr A* from the EHT Collaboration, we assess whether this nondetection is expected for current facilities and explore the prospects of detecting a jet with very-long-baseline interferometry (VLBI) at four frequencies: 86, 115, 230, and 345 GHz. We produce synthetic image reconstructions for current and next-generation VLBI arrays at these frequencies that include the effects of interstellar scattering, optical depth, and time variability. We find that no existing VLBI arrays are expected to detect the jet in these best-bet models, consistent with observations to date. We show that next-generation VLBI arrays at 86 and 115 GHz—in particular, the EHT after upgrades through the ngEHT program and the ngVLA—successfully capture the jet in our tests due to improvements in instrument sensitivity and (u, v) coverage at spatial scales critical to jet detection. These results highlight the potential of enhanced VLBI capabilities in the coming decade to reveal the crucial properties of Sgr A* and its interaction with the Galactic center environment.
Turbulence Revealed by Wavelet Transform: Power Spectrum and Intermittency for the Velocity Field of the Cosmic Baryonic Fluid
Authors: Wang 王 Yun 云 , He 何 Ping 平
Published: October 2024

We use continuous wavelet transform techniques to construct the global and environment-dependent wavelet statistics, such as energy spectrum and kurtosis, to study the fluctuation and intermittency of the turbulent motion in the cosmic fluid velocity field with the IllustrisTNG simulation data. We find that the peak scale of the energy spectrum defines a characteristic scale, which can be regarded as the integral scale of turbulence, and the Nyquist wavenumber can be regarded as the dissipation scale. With these two characteristic scales, the energy spectrum can be divided into the energy-containing range, the inertial range, and the dissipation range of turbulence. The wavelet kurtosis is an increasing function of the wavenumber k, which first grows rapidly then slowly with k, indicating that the cosmic fluid becomes increasingly intermittent with k. In the energy-containing range, the energy spectrum increases significantly from z = 2 to 1, but remains almost unchanged from z = 1 to 0. We find that both the environment-dependent spectrum and kurtosis are similar to the global ones, and the magnitude of the spectrum is smallest in the lowest-density and largest in the highest-density environment, suggesting that the cosmic fluid is more turbulent in a high-density than in a low-density environment. In the inertial range, the energy spectrum’s exponent is steeper than both the Kolmogorov and Burgers exponents, indicating more efficient energy transfer compared to Kolmogorov or Burgers turbulence.

The spectra were modeled using a Markov Chain Monte Carlo forward-modeling method, which achieved median precisions of σ
RV = 0.4 km s−1 and

One-half of our sample (138 sources) are previously known members of nearby young clusters and moving groups, and we identified three new kinematic members of the Argus or Carina Near moving groups, 2MASS J05402570+2448090, 2MASS J14093200+4138080, and 2MASS J21272531+5553150. Excluding these sources, we find that the majority of our sample have kinematics consistent with the Galactic thin disk, and 11 sources are associated with the intermediate thin/thick disk. The field sample has a velocity dispersion of 38.2 ± 0.3 km s−1, equivalent to an age of 3.30 ± 0.19 Gyr based on empirical age–velocity dispersion relations, and a median

of 17 km s−1. For 172 sources with multiepoch observations, we identified 37 as having significant RV variations, and determined preliminary orbit parameters for 26 sources with four or more epochs, nine of which are short-period binary candidates. For 40 sources with photometric variability periods from the literature less than 5 days and

Europa’s H2O2: Temperature Insensitivity and a Correlation with CO2
Authors: Wu Peiyu , Trumbo Samantha K. , Brown Michael E. , de Kleer Katherine
Published: October 2024

H2O2 is part of Europa’s water-ice radiolytic cycle and a potential source of oxidants to Europa’s subsurface ocean. However, factors controlling the concentration of this critical surface species remain unclear. Though laboratory experiments suggest that Europa’s H2O2 should be concentrated in the coldest, most ice-rich regions toward the poles, Keck adaptive optics observations have shown the strongest H2O2 signatures in comparatively warm, salt-bearing terrain at low latitudes. As a result, it was suggested that the local non-ice composition of these terrains—particularly hypothesized enrichments of CO2—may be a more dominant control on H2O2 than temperature or water-ice abundance. Here we use observations of Europa from the NASA Infrared Telescope Facility, Keck Observatory, and JWST to disentangle the potential effects of temperature and composition. In order to isolate the effect of temperature on Europa’s H2O2, we use the ground-based observations to assess its response to temperature changes over timescales associated with Europa’s daily eclipse and diurnal cycle. We use JWST Cycle 1 data to look for any geographic correlation between Europa’s H2O2 and CO2. Changes in Europa’s 3.5 μm H2O2 absorption band both from pre- to post-eclipse and across a local day suggest minimal effects of the local temperature on these timescales. In contrast, the JWST observations show a strong positive correlation between Europa’s H2O2 and CO2 bands, supporting the previously suggested possibility that the presence of CO2 in the ice may enhance H2O2 concentrations via electron scavenging.
Planetary Waves Drive Horizontal Variations in Trace Species in the Venus Deep Atmosphere
Authors: Cohen Maureen , Holmes James , Lewis Stephen , Patel Manish
Published: October 2024

The deep atmosphere of Venus remains mysterious because of the planet’s high, optically thick cloud decks. While phenomena such as the observed decadal fluctuations in sulfur dioxide abundance above the clouds could shed light on conditions below, poor understanding of vertical and horizontal transport limits such an approach. Nightside spectral windows permit observation of trace gas species in the lower atmosphere, but incomplete understanding of the circulation makes the distribution of these species challenging to interpret. We performed two simulations with the Venus Planetary Climate Model including an age of air calculation to investigate tracer transport (a) between the surface and the stagnant lower haze layer and (b) between the cloud deck and the observable upper atmosphere. We find a timescale on the order of many decades for surface-to-lower haze layer transport and ∼1.4 yr from the lowest cloud deck to 101 km. The extreme slowness of transport from the surface to the clouds makes it unlikely that compositional variability at the surface could affect the upper atmosphere sulfur dioxide abundance on observed timescales. Planetary-scale Rossby waves with a zonal wavenumber of 1 in both hemispheres are found to circumnavigate the planet in the deep atmosphere in 36 Earth days. These waves are associated with gyres that collect tracers and areas of upwelling that transport them to higher altitudes, leading to significantly younger air at polar latitudes in the altitude range of 25–45 km. The existence of chemically enhanced traveling Rossby gyres could explain the observed deep atmosphere carbon monoxide variability.

Published: October 2024

This review aims to briefly describe and summarize data from various studies on the role and the link between serum Total Antioxidant Status (TAS) levels in patients with BPH and PC, as well as other more widely available endogenous antioxidants, the levels of markers of inflammation (CRP, Leuc.), as well as the link between the values of endogenous antioxidants and various harmful factors. Their levels and adequate assessment could help in the proper management of patients with BPH and PC, as well as in reducing morbidity.
Diversity and differentiation of the Chelonus (Microchelonus) species of the Galapagos archipelago (Hymenoptera, Braconidae, Cheloninae)

Published: October 2024

Despite the significance of the Galapagos archipelago, the richness of diverse groups such as braconid wasps remains poorly studied. Seven species of chelonine Braconidae are recorded for the Galapagos islands for the first time: Chelonus buscki Viereck, 1912, Chelonus carinatus Provancher, 1881, Chelonus johni Marsh, 1979, Chelonus refluus (Papp, 2010), Chelonus sulcifera (Papp, 2016), Chelonus topali (Papp, 1999), and Chelonus turgoclarus (Papp, 2010). No endemic species were identified for the islands. We also explore island population differences with respect to island area, age, and distance between islands. The populations of C. buscki and C. carinatus were statistically differentiated between islands. Morphological differences were associated with island area only for C. buscki while no relationship was found between differentiation and age or geographic distance between islands for any species. These results could be a consequence of recent colonization events.
Proposed Solutions and Associated Problems Regarding the Shortage of Doctors in Essential Medical Fields

Published: October 2024

Recently, a sudden increase of 2,000 in the number of medical students has led to massive and prolonged strikes in medical fields. Although it remains controversial whether there is actually a shortage of doctors, many people, including physicians, agree that there is a shortage in essential medical fields. Recently, both the government and the Supreme Court have proposed several solutions in response to the problem. In this article, I would like to discuss the suggested solutions and their problems regarding the issue.
