Abstract. To better understand the surface properties of the Antarctic ice sheet, we measured the specific surface area (SSA) of surface snow during two round-trip traverses between a coastal base near Syowa Station, located 15 km inland from the nearest coast, and Dome Fuji, located 1066 km inland, in East Antarctica from November 2021 to January 2022. Using a handheld integrating sphere snow grain sizer (HISSGraS), which directly measures the snow surface without sampling, we collected 215 sets of SSA data, with each set comprising measurements from 10 surfaces along a 20 m transect. The measured SSA shows no elevation or temperature dependence between 15 and 500 km from the coast (elevation: 615–3000 m), with a mean and standard deviation of 25 ± 9 m2 kg−1. Beyond this range, SSA increases toward the interior, reaching 45 ± 11 m2 kg−1 between 800 and 1066 km from the coast (3600–3800 m). SSA shows significant variability depending on surface morphologies and meteorological events. For example, (i) glazed surfaces formed by an accumulation hiatus in katabatic wind areas show low SSA (19 ± 4 m2 kg−1), decreasing the mean SSA and increasing SSA variability. (ii) Freshly deposited snow shows high SSA (60–110 m2 kg−1), but the snow deposition is inhibited by snow drifting at wind speeds above 5 m s−1. Our analyses clarified that temperature-dependent snow metamorphism, snowfall frequency, and wind-driven inhibition of snow deposition play crucial roles in the spatial variation of surface snow SSA in the Antarctic inland. The extensive dataset will enable the validation of satellite-derived and model-simulated SSA variations across Antarctica.
Tropical cyclone asymmetric eyewall evolution and intensification in a two-layer model
Authors: Cha Ting-Yu , Bell Michael M. 
Published: August 2024

Abstract. Radar and satellite imagery of numerous intensifying tropical cyclones (TCs) depict an appearance of a polygonal eyewall structure where deep convection is often located near the polygonal vertices. A recent observational study of Hurricane Michael's (2018) polygonal eyewall evolution suggests that the vorticity asymmetries are coupled with the reflectivity asymmetries during rapid intensification. Conceptual theory of a polygonal eyewall structure has been linked to vortex Rossby waves (VRWs) and the breakdown of an enhanced potential vorticity (PV) ring, but how the asymmetries affect TC intensification remains unclear. Non-divergent barotropic models have previously been employed to study polygonal eyewall dynamics, but this approach has limitations due to the importance of diabatic heating to PV generation and the intensification process. Results from prior studies motivate us to explore the nature of the relationship between asymmetric vorticity and vertical velocity in the free atmosphere and the boundary layer and their compound impacts on the TC intensification process. Here we use a simple two-layer model framework with a shallow-water model on top of a slab boundary layer (SBL) model to simulate a frictional boundary layer underneath the free atmosphere. Results from simulating a wavenumber 2 elliptical asymmetry suggest the VRW in the free atmosphere can organize the updrafts in the SBL, which is consistent with radar observations of enhanced reflectivity at the polygonal vertices. Free atmospheric divergence in the shallow-water layer does not explain the coupling between vorticity and reflectivity. The coupling can be explained to first order by the one-way boundary layer response to the pressure gradient associated with the free atmospheric vorticity asymmetries, consistent with prior studies. Further simulations that allow two-way interaction between the layers show that the organization of the updrafts out of the SBL plays a critical role in the growth of a PV ring and intensification of the mean vortex. In this framework, diabatic heating in the shallow-water layer parameterized by a mass sink driven by the free atmosphere–SBL interaction leads to rapid intensification of the vortex, thinning of the PV ring, and eventual barotropic instability and PV mixing. The simplified modeling framework with two-way interactions captures many of the essential dynamics of rapid intensification in the presence of evolving asymmetries, similar to those seen in the observations from Hurricane Michael (2018), which provides new insight into the complex interactions between dynamics and convection during hurricane intensification.

The impact of social media has been significant on various aspects of life, particularly mental health. Growing concerns about the adverse effects of social media use have prompted the exploration of experimental interventions, defined as digital detox interventions. However, it remains unclear whether digital detox interventions are effective for mental health outcomes. The aim of this study was to provide comprehensive insights into the effects of digital detox interventions on various mental health outcomes, including depression, life satisfaction, stress, and mental well-being. Following the PRISMA guidelines, systematic searches were carried out in online databases, including PubMed and ScienceDirect, within the publication range of 2013 and 2023. A total of 2578 titles and abstracts were screened, and 10 studies were included in the analysis. A risk of bias assessment was conducted using RoB 2.0 and the Newcastle-Ottawa scale, while statistical analysis was conducted using RevMan 5.4.1. Our data indicated a significant effect of digital detox in mitigating depression with the standardized mean difference (SMD: -0.29; 95%CI: -0.51, -0.07, p=0.01). No statistically significant effects were discerned in terms of life satisfaction (SMD: 0.20; 95%CI: -0.12, 0.52, p=0.23), stress (SMD: -0.31; 95%CI: -0.83, 0.21, p=0.24), and overall mental well-being (SMD: 0.04; 95%CI: -0.54, 0.62, p=0.90). These data underscore the nuanced and selective influence of digital detox on distinct facets of mental health. In conclusion, digital detox interventions significantly reduce depressive symptoms, suggesting that intentional reduction or cessation of digital engagement may help alleviate contributing factors. However, no statistically significant effects were observed in mental well-being, life satisfaction, and stress. This discrepancy may be due to the complex nature of these constructs, involving various factors beyond the scope of digital detox interventions.
Variable Efficacy of Tranexamic Acid in Geriatric Hip Fractures Treated With Arthroplasty Versus Cephalomedullary Nails

Published: August 2024

Introduction:
Geriatric hip fractures are associated with high rates of disability and mortality. Many of these patients require perioperative and postoperative allogeneic blood transfusions, which carry several noteworthy risks. A growing body of literature supports the efficacy of tranexamic acid (TXA) in geriatric hip fractures, without sufficient data examining which subgroups are likely to benefit the most.

Methods:
In this study, we sought to evaluate whether TXA was associated with reduced blood loss and transfusions in a geriatric population undergoing hip fracture fixation at our institution during a 2-year period. The first year's data were collected in a retrospective fashion before the introduction of a quality control initiative encouraging TXA administration for all geriatric hip fractures. The second year's data were collected prospectively. A subgroup analysis was conducted for patients who underwent arthroplasties.

Results:
Among the pooled cohort of patients undergoing surgery, TXA showed no benefit over control subjects for reducing blood loss or transfusion requirements. However, the subgroup of patients undergoing arthroplasty procedures showed a notable decrease in total blood loss and total units transfused during hospitalization.

Discussion:
These results suggest that TXA may be most beneficial when targeted to arthroplasties performed for geriatric hip fractures.

Authors: Galarça Sandro Lauri da Silva 
Published: August 2024

O presente artigo apresenta uma discussão teórica a respeito dos desafios empreendidos pelas práticas de Educomunicação, em que alguns pressupostos estão dados: a) o fato de que as experiências contemporâneas de educomunicação são majoritariamente mediadas pela tecnologia presente na digitalização dos processos comunicacionais; b) há uma preocupação entre os educadores de que é preciso investir no processo de alfabetização para os meios; c) o contexto das interações estabelecidas pela escola atual exige que o aprendizado midiático não se limite ao uso de determinados códigos ou conteúdos, mas avance sobre um processo mais complexo de formação crítica para os meios. As discussões aqui apresentadas são o resultado de um levantamento bibliográfico que contextualiza a Educomunicação hoje, sem esquecer do seu contexto histórico, a experiência em outros países e o modelo latino-americano que envolve não somente a discussão crítica a respeito dos meios, mas a formação de cidadãos críticos e competentes na utilização desses meios para a geração de narrativas emancipadas sobre suas próprias vidas. Acredita-se que a reflexão teórica possa contribuir com o campo epistemológico de forma relevante na formação de uma massa crítica que faça circular diferentes visões e construções simbólicas a respeito do processo de educação para a mídia, tema central do trabalho.
