Abstract

OBJECTIVES
Although segmentectomy is an acceptable alternative to lobectomy for peripheral small-sized non-small-cell lung cancer, the effectiveness of segmentectomy for inner lesions remains unknown. The aim of this study was to examine the feasibility of segmentectomy in comparison with lobectomy for inner lesions.

METHODS
We retrospectively analysed 570 patients with small (≤2 cm) cN0 non-small-cell lung cancer who underwent segmentectomy or lobectomy between January 2007 and March 2021. We focused on patients with lesions located in the inner two-thirds, which were determined using three-dimensional computed tomography (n = 227). After propensity score matching analysis based on sex, age, pulmonary function, serum carcinoembryonic antigen level, radiographic tumour findings and tumour location, we compared the surgical and oncological outcomes in patients who underwent segmentectomy (n = 66) and lobectomy (n = 66).

RESULTS
Postoperative mortality or morbidity did not differ significantly between the 2 groups. The 5-year recurrence-free and overall survival rates in the segmentectomy and lobectomy groups were 93.6% vs 84.1% and 95.8% vs 87.9%, respectively. The differences between 2 groups were not significant (P = 0.62 and P = 0.23, respectively). The 2 groups also showed no differences in loco-regional recurrence. Multivariable Cox regression analysis revealed that segmentectomy had a comparable impact on recurrence-free survival (hazard ratio, 0.61; 95% confidence interval, 0.17–2.03; P = 0.43).

CONCLUSIONS
Segmentectomy for inner-located small-sized non-small-cell lung tumours could be an acceptable treatment in comparison with lobectomy.

AbstractA key problem with research on news media trust is that it has mostly focused on general media trust and that there is limited research on how media trust might vary across levels of analysis. In this paper, we seek to remedy this by investigating whether news media trust differs depending on the topic of news coverage and whether topical trust can be distinguished from general media trust. We also investigate the antecedents of trust in news coverage of different topics and the effects of topical trust on issue (mis)perceptions. Among other things, findings show that topical media trust can be distinguished from general media trust and is a better predictor of correct perceptions on political matters.

Published: August 2022

Abstract

Background
Crude ash is categorized as an empirical method playing an important role in the nutritional interpretation of animal feeds, allowing indirect estimation of total organic matter (OM).

Objective
Our objective was to evaluate variations in laboratory procedures for crude ash quantification regarding physical parameters (i.e., time, temperature) and ashing aids and their influences on crude ash, repeatability, and discrimination power among feeds.

Methods
The “control” method was based on a simple ignition time of 3 h at 550°C. The variations are briefly described: increasing ashing time to 6 h; increasing temperature to 600°C; and using two 3 h ignition cycles at 550°C with ashing aids inclusion between them: fresh air supply, fresh air supply plus distilled water, and fresh air supply plus hydrogen peroxide. A color evaluation was also performed using a colorimetric technique. Twenty-four study materials from eight different feed types were evaluated.

Results
The crude ash results differed among the method variations, but a consistent decrease in the estimates was observed when liquid aids were applied, which also improved repeatability. Ash residues did not present a consistent color pattern among methods, but the residues were darker when the control method was applied.

Conclusion
The method of obtaining ash residues in animal feeds based on 550°C × 3 h does not have enough robustness and may overestimate crude ash in some feeds. Adjustments in either ignition time or temperature might improve crude ash test results, but the best test results are obtained using liquid ashing aids between two ignition cycles.

Highlights
The recommended method is based on the use of 550°C and two 3 h ignition cycles with water added to the ash residue between cycles.

Published: August 2022

AbstractIt’s been over a year since the outbreak of the coronavirus disease (COVID-19), which is still a global public health challenge. Many countries have implemented social distancing to prevent the risk of infection with COVID-19. As a result, children spend more time at home. Home is where burns among children occur predominantly. We hypothesized that the changes in lifestyle due to the COVID-19 outbreak may have affected pediatric emergency department (PED) visits by children sustaining burn injuries. This study was a long-term multicenter observational study. Pediatric burn patients were defined in accordance with International Classification of Disease, Tenth Edition (ICD-10). We investigated the trend in PED weekly visits by pediatric burn patients before and after the outbreak of COVID-19 and trends in the proportion of visits according to burn severity based on segmented regression analysis. The data were adjusted for seasonality due to seasonal variation in the visits. Over the past 3 years, the proportion of pediatric burn patients tended to decrease. However, it increased in the fourth week of January 2020, when COVID-19 was first confirmed in Korea. In particular, the proportion of PED visits to pediatric burn patients with severe burns increased after the COVID-19 epidemic. Our study showed increases in the proportion of PED visits among pediatric burn patients due to the spread of COVID-19. Many of these burn accidents mainly occur at home, suggesting the need for parental intervention to prevent the risk of burn injuries among children.

Abstract
Origami tessellations can be folded from a given planar pattern into a three-dimensional object with specific geometric properties, inspiring developments in various fields of science and engineering such as deployable structures, energy absorption devices, reconfigurable robots, and metamaterials. However, the range of existing origami patterns with functional properties such as flat-foldability is rather scant, as analytical solutions to constraint equations arising in the design process are generally highly complicated. In this paper, we tackle the challenging problem of automated design of scalene-faceted flat-foldable origami tessellations using an efficient metaheuristic algorithm. To this end, this study establishes constraint curves based on compatibility conditions for all six-fold (i.e., degree-6) vertices. Subsequently, a graphical method and a particle swarm optimization (PSO) method are adopted to produce optimal origami patterns. Moreover, mountain-valley assignments for the obtained geometric designs are determined using a computational approach based on mixed-integer linear programming. It turns out that the flat-foldable internal vertices of each C2-symmetric unit fragment (UF) exist as C2-symmetric pairs about the centroid of the UF. Furthermore, numerical experiments are carried out to examine the feasibility and compare the accuracy, computational efficiency, and global convergence of the proposed methods. The results of numerical experiments demonstrated that, in comparison with the graphical method, the proposed PSO method has not only a higher accuracy but also a significantly lower computational cost, enabling us to develop an intelligent computational platform to efficiently design scalene-faceted flat-foldable origami tessellations.

ABSTRACT
Meiosis is essential for evolution and genetic diversity in almost all sexual eukaryotic organisms. The mechanisms of meiotic recombination, such as synapsis, have been extensively investigated. However, it is still unclear whether signals from the cytoplasm or even from outside of the cell can regulate the meiosis process. Cilia are microtubule-based structures that protrude from the cell surface and function as signaling hubs to sense extracellular signals. Here, we reported an unexpected and critical role of cilia during meiotic recombination. During gametogenesis of zebrafish, cilia were specifically present in the prophase stages of both primary spermatocytes and primary oocytes. By developing a germ cell-specific CRISPR/Cas9 system, we demonstrated that germ cell-specific depletion of ciliary genes resulted in compromised double-strand break repair, reduced crossover formation, and increased germ cell apoptosis. Our study reveals a previously undiscovered role for cilia during meiosis and suggests that extracellular signals may regulate meiotic recombination via this particular organelle.

AbstractBackgroundThe purpose of this study was to estimate the number of individuals living with metastatic breast, prostate, lung, colorectal, or bladder cancer or metastatic melanoma in the United States using population-based data.MethodsA back-calculation method was used to estimate the number of individuals living with metastatic cancer for each cancer type from US cancer mortality and survival statistics from the Surveillance, Epidemiology, and End Results registries. The percentages of those living with metastatic cancer who advanced to metastatic disease from early stage cancer vs who were diagnosed with metastatic cancer de novo were calculated. One- and 5-year relative survival rates for de novo metastatic cancer were compared by year of diagnosis to assess time trends in survival.ResultsIt is estimated that, in 2018, 623 405 individuals were living with metastatic breast, prostate, lung, colorectal, or bladder cancer, or metastatic melanoma in the United States. This number is expected to increase to 693 452 in 2025. In 2018, the percentage of metastatic cancer survivors who were initially diagnosed with early stage cancer and advanced to metastatic cancer ranged from 30% for lung cancer to 72% for bladder cancer.ConclusionsThis study demonstrates increasing numbers of individuals living with metastatic cancer of the 6 most common cancer types in the United States. This information is critical for informing the allocation of research efforts and healthcare infrastructure needed to address the needs of these individuals.

Published: August 2022

Abstract
Constrictive pericarditis is an uncommon complication of acute pericarditis, mainly caused by non-idiopathic sources. Pneumopericardium is the presence of air in the pericardial sac resulting from various procedures and circumstances, including trauma, iatrogenic, non-iatrogenic and natural causes. Here, we report a 16-year-old girl who came to the cardiology outpatient complaining of weakness, abdominal distention and shortness of breath while lying down and exertion. An echocardiography evaluation revealed a thickened precordium and massive pericardial effusion. Pericardiocentesis was performed for diagnosis and treatment purposes. Despite the patient’s remaining symptomatic and having no improvement following the procedure, we decided to perform chest computed tomography, which revealed a thickened pericardium with pneumopericardium. Partial pericardiectomy was performed successfully, and the sample was sent to the pathology department, which confirmed tuberculous constrictive pericarditis. The patient’s symptoms improved, and she was discharged on postoperative Day 5 standing on her foot.

Abstract
We conceptualized Surgical Accredited and Trained Healthcare Initiative (SATHI) as a community-based worker through which patients who are unaware or undecided of surgical conditions would be linked to service providers. These personnel will help patients to attain the benefits of health schemes and will offer counseling through trust-building and elimination of fear of surgical procedures to reduce the surgical unmet needs. Our baseline study identified five common surgical problems among the study population: extremity injuries/wounds; kidney stones; cataracts; abdominal pain, including external hernias, and menstrual disorders. Based on these findings, we designed a modular, skills-focused curriculum and recruited six full-time staff who have undergone didactic and practical training. Upon finding any suspected health condition, SATHI staff are trained to encourage the patient and their family to seek medical advice. They are also equipped with the basic information about the surgical management of these conditions and will offer preoperative and post-operative surgical care and psychosocial support. This publication describes the process of development of training material, methods and process. Each SATHI worker has been assigned 1000 households (~5000 population). Based on our estimates, he/she will have to cater to 64 cases of unmet surgical needs if the unmet need is 40%. This means a SATHI worker would have approximately five to six cases of unmet surgical needs per month. We are planning to analyze the survey findings, document the process of implementation, and based on learnings from the pilot project, modify the training material and protocol.
Mesoscopic energy ranking constraints in the IllustrisTNG simulations
Authors: Dantas Christine C 
Published: August 2022

ABSTRACT
We revisited the problem of mixing in a gravitational N-body system from the point of view of the ordering of coarse-grained cells in the one-particle energy space, here denoted energy ranking preservation (ERP). This effect has been noted for some time in simulations, although individual particle energies and their phase-space variables mix considerably. The present investigation aimed to map ERP in terms of parameters involving the collective range in which it is effective, as well as in terms of global and historical characterizations of gravitational systems evolving towards equilibrium. We examined a subset of the IllustrisTNG cosmological magnetohydrodynamical simulations (TNG50-4 and TNG100-3), considering both their full and dark-only versions. For each simulation, we selected the 20 most massive haloes at redshift z = 0, tracing their ERP fractions back at selected redshift markers (z = {1.0, 5.0, 10 0}), and for a coarse-graining set ranging from 5 to 30 energy bins. At the redshift marker z = 1, we found high ERP fractions (above ${\sim}80\,\hbox{per cent}$) in both simulations, regardless of the coarse-graining level. The decline in ERP fractions with redshift was roughly a function of mass and fractional mass increase in the analysed TNG50-4 haloes, but not in the TNG100-3 ones, indicating a possible relative susceptibility of the ERP effect to mass accretion for haloes less massive than ${\sim}10^{14} \, {\rm M}_{\odot }$. We confirmed earlier indications in the literature concerning a possible ‘mesoscopic’ constraint operative in a time span of at least several Gyr.

ABSTRACT
In this work, we investigate how the central stellar metallicity ([Z/H]) of 1363 galaxies from the SAMI galaxy survey is related to their stellar mass and a proxy for the gravitational potential, $\Phi = \log _{10}\left(\frac{M_*}{M_{\odot }} \right) - \log _{10}\left(\frac{r_e}{\mathrm{kpc}} \right)$. In agreement with previous studies, we find that passive and star-forming galaxies occupy different areas of the [Z/H]–M* plane, with passive galaxies having higher [Z/H] than star-forming galaxies at fixed mass (a difference of 0.23 dex at log10(M*/M⊙) = 10.3). We show for the first time that all galaxies lie on the same relation between [Z/H] and Φ, and show that the offset in [Z/H] between passive and star-forming galaxies at fixed Φ is smaller than or equal to the offset in [Z/H] at fixed mass (an average Δ[Z/H] of 0.11 dex at fixed Φ compared to 0.21 dex at fixed mass). We then build a simple model of galaxy evolution to explain and understand our results. By assuming that [Z/H] traces Φ over cosmic time and that the probability that a galaxy quenches depends on both its mass and size, we are able to reproduce these offsets in stellar metallicity with a model containing instantaneous quenching. We therefore conclude that an offset in metallicity at fixed mass cannot by itself be used as evidence of slow quenching processes, in contrast to previous studies. Instead, our model implies that metal-rich galaxies have always been the smallest objects for their mass in a population. Our findings reiterate the need to consider galaxy size when studying stellar populations.
An estimate of the mass of the Milky Way from the Magellanic Stream

Published: August 2022

ABSTRACT
We present a model for the formation of the Magellanic Stream (MS) due to ram pressure stripping. We model the history of the Small and Large Magellanic Clouds in the recent cosmological past in a static Milky Way (MW) potential with diffuse halo gas, using observationally motivated orbits for the Magellanic Clouds derived from HST proper motions within the potential of the MW. This model is able to reproduce the trailing arm but does not reproduce the leading arm feature, which is common for models of the stream formation that include ram pressure stripping effects. While our model does not outperform other models in terms of matching the observable quantities in the MS, it is close enough for our ultimate goal – using the MS to estimate the MW mass. By analysing our grid of models, we find that there is a direct correlation between the observed stream length in our simulations and the mass of the MW. For the observed MS length, the inferred MW mass is 1.5 ± 0.32 × 1012$\, \mathrm{M}_\odot$, which agrees closely with other independent measures of the MW mass. We also discuss the MS in the context of H i streams in galaxy clusters, and find that the MS lies on the low-mass end of a continuum from Hickson groups to the Virgo cluster. As a tracer of the dynamical mass in the outer halo, the MS is a particularly valuable probe of the MW’s potential.

ABSTRACT
In this work, photometric and spectroscopic analyses of a very low-luminosity Type IIb supernova (SN) 2016iyc have been performed. SN 2016iyc lies near the faint end among the distribution of similar supernovae (SNe). Given lower ejecta mass (Mej) and low nickel mass (MNi) from the literature, combined with SN 2016iyc lying near the faint end, one-dimensional stellar evolution models of 9–14 M⊙ zero-age main-sequence (ZAMS) stars as the possible progenitors of SN 2016iyc have been performed using the publicly available code mesa. Moreover, synthetic explosions of the progenitor models have been simulated, using the hydrodynamic evolution codes stella and snec. The bolometric luminosity light curve and photospheric velocities produced through synthetic explosions of ZAMS stars of mass in the range of 12–13 M⊙ having a pre-supernova radius R0 = (204–300) R⊙, with Mej = (1.89–1.93) M⊙, explosion energy Eexp = (0.28–0.35) × 1051 erg, and MNi &lt; 0.09 M⊙, are in good agreement with observations; thus, SN 2016iyc probably exploded from a progenitor near the lower mass limits for SNe IIb. Finally, hydrodynamic simulations of the explosions of SN 2016gkg and SN 2011fu have also been performed to compare intermediate- and high-luminosity examples among well-studied SNe IIb. The results of progenitor modelling and synthetic explosions for SN 2016iyc, SN 2016gkg, and SN 2011fu exhibit a diverse range of mass for the possible progenitors of SNe IIb.
Clustering redshifts with the 21cm-galaxy cross-bispectrum

Published: August 2022

ABSTRACT
The cross-correlation between 21-cm intensity mapping (IM) experiments and photometric surveys of galaxies (or any other cosmological tracer with a broad radial kernel) is severely degraded by the loss of long-wavelength radial modes due to Galactic foreground contamination. Higher-order correlators are able to restore some of these modes due to the non-linear coupling between them and the local small-scale clustering induced by gravitational collapse. We explore the possibility of recovering information from the bispectrum between a photometric galaxy sample and an IM experiment, in the context of the clustering-redshifts technique. We demonstrate that the bispectrum is able to calibrate the redshift distribution of the photometric sample to the required accuracy of future experiments such as the Rubin Observatory, using future single-dish and interferometric 21-cm observations, in situations where the two-point function is not able to do so due to foreground contamination. We also show how this calibration is affected by the photometric redshift width σz,0 and maximum scale kmax. We find that it is important to reach scales $k \gtrsim 0.3\, h\, {\rm Mpc}^{-1}$, with the constraints saturating at around $k\sim 1\, h\, {\rm Mpc}^{-1}$ for next-generation experiments.
