Exploring the Cognitive-Communication Challenges of Adults With Histories of Traumatic Brain Injury and Criminal Justice System Involvement: A Pilot Study
Authors: Wiseman-Hakes Catherine , Magor Tamsin , Bauman Nicole , Colantonio Angela , Matheson Flora I.
Published: January 2023

Introduction:

The prevalence of traumatic brain injury (TBI) in the criminal justice system (CJS) is well known. Furthermore, the impact of TBI on communication has been well documented; however, no study has explored the communication challenges of those with TBI in the CJS or considered their implications within CJS contexts. Moreover, no study has examined the possible differences in communication between those with TBI and CJS history and those with TBI but no CJS history.

Purpose:

This cross-sectional pilot study provides a preliminary exploration of the cognitive-communication challenges in a sample of adults with histories of TBI and CJS involvement compared with a sample of adults with histories of TBI but no CJS involvement.

Method:

Eight individuals with histories of TBI and CJS involvement were recruited through community agencies. The La Trobe Communication Questionnaire (LCQ) was administered to collect self-reported data on perceived cognitive-communication abilities, including social communication behaviors. Findings were examined and then compared with a previously studied sample of 160 individuals with TBI. Logistic regressions were calculated to determine whether response scores on the LCQ would be predictive of group membership (i.e., TBI + CJS or TBI only).

Results:

A range of cognitive-communication challenges were reported by both groups. A logistic regression analysis demonstrated a reasonable inference that LCQ responses may predict group membership and support the potential for statistically significant and meaningful results to justify future studies.

Conclusions:

These challenges have the potential to negatively impact the success of communication interactions within the CJS and illustrate a need for speech-language pathology services for individuals with TBI in the CJS. The nature and magnitude of between-group differences merits further investigation with larger samples to explore whether any specific cognitive-communication challenge is unique to, or predictive of, CJS involvement for purposes of targeted assessment and intervention.
Applicability of the acoustic–electrical joint detection method to identify defects in gas insulated system
Authors: Sun Jixing , Fan Yongzhi , Qiu Weifan , Song Sibo , Tan Xinyu , Tian Yu , Jiao Xuewen , Wang Huili , Wu Nana
Published: January 2023

There are many defects in gas‐insulated metal‐enclosed switchgear (GIS) and gas‐insulated transmission lines (GIL) that may cause accidents, such as floating potentials, metal particles, air gaps, and cracks in support insulators. Nevertheless, to‐this‐date, there is no effective method to recognize them to adjust their operation status. Accordingly, this study compared three typical defect models to explore the partial discharge process, and three typical experimental models were established to identify the characteristic parameters of acoustic and electrical information in the development of defects. The research study shows that that as the voltage increases, the partial discharge of free‐metal‐particle defects and air‐gap defects obtained by the pulse‐current method increase gradually. A sudden increase also occurred in the partial discharge of the floating potential defect. The discharge amount of free conductive particles obtained by an ultrahigh‐frequency detection method was distributed symmetrically on both sides of the applied voltage peak, and the other two defects were on one side of the peak and yielded an obvious phase difference. The particle collision signal obtained by the ultrasonic method was obvious, but had no obvious phase relationship with the applied voltage. However, the obtained floating potential defect information had obvious phase differences, and the ultrasonic method was not sensitive to air‐gap defects. The three typical defects can be identified by the combined method more accurately; this provides a theoretical basis and data support for GIS and GIS voltage tests, detection technologies, and online monitoring methods.
Cosmic rate of type IIn supernovae and its evolution with redshift
Authors: Cold C. , Hjorth J.
Published: January 2023

Context. Type IIn supernovae potentially constitute a large fraction of the gravitationally lensed supernovae predicted to be found with upcoming facilities. However, the local rate is used for these estimates, which is assumed to be independent of properties such as the host galaxy mass. Some studies hint that a host galaxy mass bias may exist for IIn supernovae.

Aims. This paper aims to provide an updated local IIn supernova-to-core-collapse ratio based on data from the Palomar Transient Factory (PTF) and the Zwicky Transient Facility (ZTF) Bright Transient Survey (BTS). Furthermore, the goal is to investigate the dependency of the IIn supernova peak magnitude on the host galaxy mass and the consequences of a possible host galaxy mass preference on the volumetric rate of type IIn supernovae.

Methods. We constructed approximately volume-limited subsamples to determine the local IIn supernova-to-core-collapse ratio. We investigated the absolute peak magnitude of a subsample of type IIn and superluminous II or IIn supernovae exploring how this relates to the i-band magnitude of the host galaxies (as a proxy for stellar mass). We presented a method to quantify the effect of a potential preference for low-mass host galaxies utilizing the UNIVERSEMACHINE algorithm.

Results. The IIn supernova-to-core-collapse ratios for PTF and BTS are 0.046 ± 0.013 and 0.048 ± 0.011, respectively, which results in a ratio of 0.047 ± 0.009, which is consistent with the ratio of 0.05 currently used to estimate the number of gravitationally lensed IIn supernovae. We report fainter host galaxy median absolute magnitudes for type IIn brighter than −20.5 mag with a 3σ significance. If the IIn supernova-to-core-collapse ratio were described by the power law model IIn/CC = 0.15 × log(M/M⊙)−0.05, we would expect a slightly elevated volumetric rate for redshifts beyond 3.2.
New compact hierarchical triple system candidates identified using Gaia DR3

Published: January 2023

Aims. We introduce a novel way to identify new compact hierarchical triple stars by exploiting the huge potential of Gaia DR3 and also its future data releases. We aim to increase the current number of compact hierarchical triple systems significantly.

Methods. We used several eclipsing binary catalogs from different sky surveys that list a total of more than 1 million targets to search for Gaia DR3 non-single-star orbital solutions with periods substantially longer than the eclipsing periods of the binaries. Those solutions in most cases are likely to belong to outer orbits of tertiary stars in those systems. We also attempted to validate some of our best-suited candidates using TESS eclipse timing variations.

Results. We find 403 objects with suitable Gaia orbital solutions of which 27 are already known triple systems, leaving 376 newly identified hierarchical triple system candidates in our sample. We find the cumulative probability distribution of the outer orbit eccentricities to be very similar to those found in earlier studies based on observations of the Kepler and OGLE missions. We find measurable nonlinear eclipse timing variations or third-body eclipses in the TESS data for 192 objects which we also consider to be confirmed candidates. Of these, we construct analytical light-travel time effect models for the eclipse timing variations of 22 objects with wellsampled TESS observations. We compare the outer orbital parameters from our solutions with those from the Gaia solutions and find that the most reliable orbital parameter is the orbital period, while the values of the other parameters should be used with caution.
The intense production of silicates during the final AGB phases of intermediate mass stars
Authors: Marini E. , Dell’Agli F. , Kamath D. , Ventura P. , Mattsson L. , Marchetti T. , García-Hernández D. A. , Carini R. , Fabrizio M. , Tosi S.
Published: January 2023

Context. The formation of silicates in circumstellar envelopes of stars evolving through the asymptotic giant branch (AGB) is still highly debated given the uncertainties affecting stellar evolution modelling, the description of the dust formation process, and the capability of silicate grains to accelerate stellar outflows via radiation pressure.

Aims. We study the formation of dust in the winds of intermediate mass (M ≥ 4 M⊙) stars of solar metallicity while evolving through the AGB phase. We tested the different treatments of the mass-loss mechanism by this class of stars, with the aim of assessing their contribution to the general enrichment of silicates of the interstellar medium of galaxies and, on more general grounds, to the silicates budget of the Universe.

Methods. We consider a sub-sample of AGB stars, whose spectral energy distribution (SED) is characterised by deep absorption features at 10 μm and 18 μm, which can be regarded as the class of stars providing the most relevant contribution to the silicates’ production across the Universe. Results from stellar evolution and dust formation modelling were used to fit the observed SED and to reproduce, at the same time, the detected pulsation periods and the derived surface chemical composition. This analysis leads to the derivation of tight constraints on the silicates’ production rates experienced by these sources during the final AGB stages.

Results. Two out of the four sources investigated are interpreted as stars currently undergoing hot bottom burning (HBB), evolving through phases close to the stage when the mass-loss rate is largest. The remaining two stars are likely evolving through the very final AGB phases, after HBB was turned off by the gradual consumption of the convective mantle. Mass-loss rates of the order of 1 × 10−4 M⊙ yr−1 to 2 × 10−4 M⊙ yr−1 are required when looking for consistency with the observational evidence. These results indicate the need for a revision of the silicate yields by intermediate mass stars, which are found to be ∼3 times higher than previously determined.
Essais de gonflement avec mesure de la contrainte radiale à l’œdomètreK0à haute pression
Authors: Serratrice Jean François
Published: January 2023

Plusieurs séries d’essais de gonflement ont été réalisées sur des argiles et des marnes plastiques à l’aide d’un œdomètreK0à haute pression. Ces essais sont accompagnés par des essais de gonflement en parallèle à basse pression. Des essais triaxiaux à haute pression ont fourni la résistance de quelques-uns de ces terrains et leurs états limites. Après avoir présenté les matériels, les procédures d’essais et les terrains étudiés, les résultats des essais sont décrits à partir des courbes expérimentales. Chaque exemple apporte un éclairage particulier parmi les diverses réponses des terrains argileux et marneux examinés. En enrichissant les essais d’une mesure de la contrainte radiale, l’œdomètreK0à haute pression permet de décrire les chemins des contraintes suivis au cours des cycles de chargement. Cette mesure élargit le cadre d’interprétation des essais en apportant des données pertinentes sur trois aspects particuliers du gonflement œdométrique au laboratoire. Cela concerne le préchargement en phase préliminaire d’essai quand le sol est mis en présence d’eau ou l’effet de la contrainte maximale atteinte au cours des cycles de chargement. Cela concerne aussi la rupture du sol en extension en fin de déchargement, où différentes situations apparaissent suivant la résistance du sol. Les cycles à haute pression et le gonflement à basse pression produisent une déstructuration des sols et une modification de leur comportement mécanique.
Tonus et culture, de la mémoire corporelle à la transparence corporelle Une lecture transculturelle de la psychomotricité
Authors: Housseini-Houy Sabine , Camara Hawa , Moro Marie-Rose
Published: January 2023

La culture est une réalité collective qui se transmet de génération en génération à travers l’éducation, nous indique M. Mead (1963). Nous développerons l’idée que le dialogue tonico-émotionnel de J. De Ajuriaguerra cher aux Psychomotriciens est un dialogue de transmission culturelle. Le dialogue tonico-émotionnel et les soins de maternage sont les supports de cette enculturation du corps maternant au corps du nouveau-né, et cela à leur insu. Notre approche théorique déroulera 3 temps forts de la régulation tonique et émotionnelle; le tonus sensoriel intra-utérin, le tonus gestuel accueilli par son berceau culturel, les effets de transparence psychique, corporelle et culturelle du dialogue tonico-émotionnel. Nous verrons comment cette enculturation s’inscrit et se transmet dans la construction et la remémoration du corps en relation.

L’histoire de Mme R et de son bébé, reçus dans notre unité de Périnatalité, viendra soutenir cette lecture psychomotrice et transculturelle. Mme R venue en France alors qu’elle était une jeune enfant n’a pu se soutenir du processus de transparence corporelle dans sa rencontre à son bébé. Nous développerons l’hypothèse que cette migration précoce a eu un effet sur la construction de sa mémoire corporelle et, a été un empêchement à la mise en route du processus de transparence corporelle ainsi que culturelle. Nous tenterons alors d’inventer et d’adapter un cadre de soins, pour cette dyade, au travers d’une expérience de suivi à domicile et au sein d’une unité ambulatoire de périnatalité.

Published: January 2023

Bleeding is a major complication in coronary artery bypass graft surgery. Antifibrinolytic agents like serine protease inhibitor aprotinin can decrease postoperative bleeding and complications of cardiac surgery. However, the effects of aprotinin on vascular function are not completely elucidated. We compared the ex vivo vascular function of left internal mammary arteries from patients undergoing coronary artery bypass graft surgery with and without intraoperative application of aprotinin using a Mulvany Myograph. Human internal mammary arteries were treated with aprotinin ex vivo and tested for changes in vascular function. We analyzed the impact of aprotinin on vascular function in rat aortic rings. Finally, impact of aprotinin on expression and activity of endothelial nitric oxide synthase was tested in human endothelial cells. Intraoperative application of aprotinin did not impair ex vivo vascular function of internal mammary arteries of patients undergoing coronary artery bypass graft surgery. Endothelium-dependent and -independent relaxations were not different in patients with or without aprotinin after nitric oxide synthase blockade. A maximum vasorelaxation of 94.5%±11.4vs. 96.1%±5.5% indicated a similar vascular smooth muscle function in both patient groups (n=13 each). Long-term application of aprotinin under physiological condition preserved vascular function of the rat aorta. In vitro application of increasing concentrations of aprotinin on human endothelial cells resulted in a similar expression and activity of endothelial nitric oxide synthase. In conclusion, intraoperative and ex vivo application of aprotinin does not impair the endothelial function in human internal mammary arteries and experimental models.
Encountering Peritoneo-Cutaneous Perforators in Microsurgical DIEP Flap Breast Reconstruction

Published: January 2023

The vascular anatomy of the deep inferior epigastric artery perforator (DIEP) flap has been well studied in the planning for autologous breast reconstruction. Preoperative imaging with computed tomography angiography (CTA) provides accurate assessment of this vascular anatomy, which varies widely across patients. Several papers to date have described their encounter with an anomalous “epiperitoneal” or “peritoneo-cutaneous” perforator during flap harvest, a perforator that pierces the posterior rectus sheath from a peritoneal origin, to traverse rectus abdominis and supply the DIEP flap integument. In the course of over 3,000 CTA assessments of the vascular anatomy of the abdominal wall, we have encountered dominant peritoneo-cutaneous perforators in 1% of cases, and smaller perforators seen in many more cases, approaching 5% of cases. With increasing sensitivity of imaging, we also describe a unique case of multiple large bilateral peritoneo-cutaneous perforators, and present these findings in the context of DIEP flap harvest. It is critical to recognize these peritoneo-cutaneous perforators preoperatively to avoid mistaking them for a DIEP during the raising of a DIEP flap. The routine use of preoperative CTA enables the safe identification of individual vascular anatomy, including significant peritoneo-cutaneous perforators.

Enantioconvergent transition-metal-catalyzed cross-coupling reactions of racemic α-silyl and α-boryl reagents represent one of the key tools to afford highly enantioenriched α-chiral silanes and boranes. The approach traces back the use of α-silyl nucleophiles, employing palladium precatalysts. More recent work makes use of α-silyl and α-boryl electrophiles under nickel and copper catalysis. The limits of this field have been significantly extended by the design and development of numerous chiral ligands. In this short review, the progress made in this rapidly evolving field is summarized.

Hemolytic uremic syndrome (HUS) is a triad of hemolytic anemia, thrombocytopenia, and acute renal failure. In critically ill children with HUS, extrarenal manifestations may require intensive care unit admission and extracorporeal membrane oxygenation (ECMO) support. Outcomes specific to HUS and ECMO in children have not been well investigated. The primary aim of this project was to query a multicenter database to identify risk factors associated with mortality in HUS patients supported on ECMO. A secondary aim was to identify factors associated with ECMO utilization in children with HUS. Utilizing the Pediatric Health Information System database (January 2004 and September 2018), this retrospective, multicenter cohort study identified the index HUS hospitalization among children aged 0 to 18 years. Univariate analysis was used to compare demographics, clinical characteristics, and procedures to identify risk factors associated with adverse outcomes. Among 4,144 subjects, 37 were supported on ECMO. Survival for those on ECMO support was 54%. Among nonsurvivors, 59% of deaths occurred within 14 days of hospitalization. The mean hospital LOS was 15.9 days in nonsurvivors versus 53.9 days for survivors (p < 0.001). When comparing subjects supported on ECMO to those who were not, patients with ECMO support had statistically longer hospital LOS and higher rates of extrarenal involvement (p < 0.001). This study found a mortality rate of 46% among HUS patients requiring ECMO. The investigated clinical risk factors were not associated with mortality among the ECMO population. The study identifies risk factors associated with ECMO utilization in children with HUS.

Objectives This is an in vitro study that aimed to evaluate the ability of different glass ionomer restorations to mask the discoloration produced following silver diamine fluoride (SDF) only and after potassium iodide (KI) application.

Materials and Methods Thirty-six extracted human adult posterior teeth were collected. Box-shaped cavities (4 × 2 × 2 mm3) were prepared along the cementoenamel junction. Specimens were randomly divided into two major groups according to the materials applied under the restorations group (A) 38% silver diamine fluoride (SDF) followed by immediate application of potassium iodide (KI), group (B) 38% silver diamine fluoride (SDF) only. Each group was further subdivided according to the restorative material applied as follows (n = 6): subgroup (I) zirconia reinforced glass ionomer, subgroup (II) resin-modified glass ionomer restoration, and subgroup (III) high viscous glass ionomer restoration. Color assessment of all specimens was performed using a reflective spectrophotometer. Specimens' color was assessed color of normal dentin then assessed immediately after application of SDF (group A) and after application SDF + KI (group B) with the respective restorative material used.

Statistical Analysis Data showed parametric distribution and variance homogeneity and were analyzed using one-way analysis of variance followed by Tukey's post hoc test.

Results Intergroup comparisons showed that for SDF and SDF + KI samples, there was a significant difference between the different restorative materials (p < 0.001). For glass ionomer, SDF samples had significantly higher color change value than SDF + KI (p < 0.001), while for RMGI and zirconia reinforced glass ionomer, SDF + KI samples had significantly higher value (p < 0.001) although zirconia reinforced glass ionomer showed the least color change following SDF (6.00 ± 2.74).

Conclusion Within the limitations of this study, we could conclude that using zirconia reinforced glass ionomer could have a good masking effect on discoloration produced by SDF. While the resin-modified glass ionomer restoration showed more discoloration and darkening effect even after using of KI. Also, using KI in combination with SDF had a good masking effect on discoloration that produced by SDF.

Objective Pregnant women are more at risk to suffer dental infection. Untreated dental infection during pregnancy can lead to more serious problems to mothers and their children, such as premature birth and low birth weight. This study aims to analyzed the relationship between oral hygiene status (OHI-S) and the expression of Porphyromonas gingivalis in third trimester pregnant women.

Materials and Methods This was an observational analytic study with a cross-sectional study design. Patients consisted of 37 final trimester pregnant women, divided into good OHI-S and fair OHI-S. The P. gingivalis expression was measured using real-time qPCR from the mucosal swab.

Results The P. gingivalis expression found no differences between good OHI-s and fair OHI-S (p = 0.557).

Conclusion Based on this study, although there was no significant difference in P. gingivalis expression in the final trimester based on their oral health status, oral health is considered important to be taken care of during pregnancy.

Objective To describe the anatomy related to a novel approach to the petroclival region through the mandibular fossa for the treatment of petroclival and anterior pontine lesions.

Design Five dry skulls were examined for surgical approach. Three adult cadaveric heads underwent bilateral dissection. One cadaveric head was evaluated with computed tomography after dissection.

Setting This study was performed in an academic medical center.

Participants Neurosurgical anatomy researchers performed this study using dry skulls and cadaveric heads.

Main Outcome Measurements This was a proof-of-concept anatomical study.

Results The mandibular fossa approach uses a vertical preauricular incision above the facial nerve branches. Removal of the temporomandibular joint exposes the mandibular fossa. The anterior boundary is the mandibular nerve at the foramen ovale, and the posterior boundary is the jugular foramen. The chorda tympani, eustachian tube, and tensor tympani muscle are sectioned. The carotid artery is transposed out of the petrous canal, and a petrosectomy is performed from Meckel's cave to the foramen magnum and anterior occipital condyle. Dural opening exposes the anterior pons, vertebrobasilar junction, bilateral vertebral arteries, and the ipsilateral anterior and posterior inferior cerebellar arteries. At completion, the temporomandibular joint is reconstructed with a prosthetic joint utilizing a second incision along the mandible.

Conclusions The mandibular fossa approach is a new trajectory to the petroclival region and the anterior pons. It combines the more anterior angle of endoscopic approaches along with the enhanced control of open approaches. Further study is necessary before this approach is used clinically.

Published: January 2023

Flavonoids are a large group of naturally occurring polyphenolic compounds that are almost universally present in various plant parts such as fruits, berries, leaves, and tubers. These compounds are synthesized in plants in reaction to environmental stressors such as microbial infections. The antioxidant properties in these flavonoids provide us with numerous health benefits. They can be extracted from said natural sources via methods such as maceration and boiling all the way to advanced methods such as microwaves and ultrasounds.

Numerous studies have been conducted to research the protective role that flavonoids can play in preventing infectious diseases in humans. The present modalities of treating such infectious diseases rely solely on chemotherapeutic agents and adjunctive therapies such as palliative and supportive care. These chemotherapeutic agents, primarily antibiotics, cause a degeneration of our immunity and an increased susceptibly to several other diseases. Thus, it is crucial that our methods in dealing with infections focus on prevention. This can be achieved by strengthening our immune system, which is the primary line of defense against such diseases. Flavonoids can help boost our immunity, fight infections, and decrease the incidence of antibiotic resistance.

Hence, these natural compounds are being largely studied and used as nutraceuticals to supplement our daily diet and successfully reduce the occurrence of major infectious diseases in our body.
Delineating magnetization dynamics in solution-processed doped yttrium iron garnet thin films
Authors: Patel Shreya K. , Karaba C. Ty , Tolbert Sarah H.
Published: January 2023

In this work, thin films of ruthenium-doped and cerium-doped yttrium iron garnet were deposited on silicon using solgel chemistry. Doped YIG could be produced in phase pure form up to a precursor stoichiometry of Y3Ru0.1Fe4.9O12 and Ce0.7Y2.3Fe5O12. Both dopants significantly increase the coercivity and anisotropy field of the materials either due to domain wall pinning or increased spin–orbit coupling from the dopant. To delineate these two effects, the dynamic magnetic properties were studied using strip line ferromagnetic resonance (FMR). The FMR linewidth was separated into intrinsic loss and inhomogeneous line broadening. Inhomogeneous line broadening was found to dominate the magnetic losses in all the films likely due to magnon scattering off grain boundaries, but the Gilbert damping remained fairly low. By comparing the two dopants, it was found that Gilbert damping increased more in Ce:YIG films than in Ru:YIG films. This finding was corroborated by changes in the anisotropy field of the films, indicating a larger contribution from spin–orbit coupling from cerium than from ruthenium. Surprisingly, while magnetic loss globally increased with higher substitution, adding a small amount of dopant actually reduced the inhomogeneous line broadening in both sets of films. This was corroborated by crystallite size. The damping in Ru:YIG also decreased with a small amount of the dopant, which has been predicted by Kittel for doped garnets. Thus, it follows that there is an ideal doping regime where solgel YIG can be doped at low levels without increasing magnetic loss.
