Dielectric Biodegradable Biopolymer‐Based Graphene Nanocomposites for Use in the Packaging Industry and Capacitor Application
Authors: Gürler Nedim , Torğut Gülben 
Published: August 2022

AbstractIn this study, polyhydroxyalkanoate (PHA) and polylactic acid (PLA)‐Graphene (G) nanocomposite films were synthesized by taking different concentrations of G via the solution casting process, and their structural, mechanical, opacity, thermal and dielectric properties were examined for the first time. Scanning electron microscopy (SEM) was used for investigating surface morphology. Films containing graphene were more opaque than films without graphene. The incorporation of graphene into the polymer matrix improved the mechanical property. The tensile strengths of the control PHA/PLA film and the graphene‐reinforced 1 %G‐PHA/PLA nanocomposite films were 18.98 and 24.34 MPa, respectively. Thermogravimetric analysis results showed that PHA/PLA−G nanocomposites had good thermal stability below 300 °C. Considering the dielectric measurements, it is seen that the dielectric constant (έ) and dielectric loss (ϵ”) decreased with increasing frequency and less changed at higher frequencies. The developer feature of graphene is remarkable in both parameters. The electrical conductivity of PHA/PLA−G nanocomposites was also examined as a function of frequency at room temperature. As the amount of G increased from 1 %wt to 5 %wt, the conductivity of the composites increased.

AbstractBackgroundContrast‐enhanced ultrasound (CEUS) features of pancreatic lesions are poorly reported in veterinary literature.MethodsQualitative and quantitative features of pancreatic benign (nodular hyperplasia [NH], cyst and abscess) and malignant (adenocarcinoma and insulinoma) lesions during B‐mode and CEUS examinations are described in 75 dogs.ResultsAdenocarcinomas (n = 23) had mixed echogenicity at B‐mode, and they were hypoenhancing or non‐enhancing at CEUS, with a non‐homogeneous and cystic enhancement pattern. Insulinomas (n = 23) appeared as hypoechoic lesions at B‐mode, and as hyperenhancing, homogeneous and solid lesions at CEUS. NH (n = 17) had an constant appearance, being hypoechoic at ultrasound (US) and isoenhancing at CEUS. Cysts (n = 7) were all anechoic, with acoustic enhancement clearly detectable at US, but were non‐enhancing at CEUS. Lastly, abscesses (n = 5) had mixed echogenicity, and they showed both hyperenhancement and non‐enhancement at CEUS. Hypoenhancement and non‐homogeneous appearance had a moderate diagnostic accuracy in the detection of adenocarcinomas. In particular, hyperenhancement was evident only in malignant lesions (adenocarcinomas and insulinomas).ConclusionCEUS, in combination with B‐mode US features, is a valuable tool for distinction of benign and malignant abnormalities of the pancreas and can potentially differentiate insulinomas from adenocarcinomas.
Overcoming Barriers to Effective Suicide Prevention in Rural Communities
Authors: Michael Kurt D. , Ramtekkar Ujjwal 
Published: August 2022

AbstractIndividuals who live in rural communities face health challenges, including a higher risk of suicide and opiate dependence, and relatively fewer healthcare resources compared to those found in urban communities. The most prominent barriers to effective suicide prevention in rural areas include limited availability of healthcare providers, transportation limitations, economic disparities, a lack of broadband access, and reluctance to seek professional treatment. Despite these barriers, school mental health partnerships and telehealth models of care have shown promise in addressing several of these barriers in practice. These two innovations will be discussed in detail and how they help overcome some of the known barriers to effective suicide prevention in rural communities.
Disclosure of Youth Suicidality: Views from Lived Experience
Authors: Willis-Powell Rowan , Fox Amanda , Cerel Julie 
Published: August 2022

AbstractInsight from individuals with lived experience suggests that unnecessary hospitalization decreases the likelihood that individuals will disclose suicidal thoughts and behaviors to providers. To improve engagement and create better outcomes for individual who experiences a suicidal crisis, clinicians should receive suicide-specific training that emphasizes personalized care for each patient that matches their level of risk. Individualized safety planning and options other than inpatient hospitalization should be prioritized when suicidal thoughts and behaviors are disclosed to providers and when the level of risk does not warrant hospitalization. This will allow youth who make such disclosures to get access to effective and minimally restrictive interventions while preventing trauma and harm. Finally, healthcare systems must focus on investing resources and research into alternatives to inpatient care as treatment for suicidal crises, and individuals with lived experience will be an essential asset to this process.
Neurobiology of Suicide in Children and Adolescents: Implications for Assessment and Treatment
Authors: Ballard Elizabeth D. , Pao Maryland 
Published: August 2022

AbstractPharmacologic and non-pharmacologic treatment of children and adolescents with suicidal thoughts and behavior have lagged behind the already sparse treatments for suicidal adults, leaving many at-risk youths undertreated. The following is a review of the neurobiological research literature focused on suicide risk in children and adolescents. Topics include the relationship of suicide risk to neuroimaging findings, impulsivity, genetics, and treatment approaches, including selective serotonin reuptake inhibitors (SSRIs), lithium, ketamine, and transcranial magnetic stimulation (TMS).

Authors: Mournet Annabelle M. , Lowry Nathan J. , Horowitz Lisa M. 
Published: August 2022

AbstractSuicide risk screening for youth in medical settings, especially in primary care, is supported and encouraged by The Joint Commission, the American Academy of Pediatrics, and the National Action Alliance for Suicide Prevention. Implementing suicide risk screening and assessment with evidence-based tools can enhance feasibility of screening programs without overburdening busy systems of care. This chapter will highlight existing research on suicide risk screening and assessment in medical settings, discuss the importance of utilizing clinical pathways to effectively manage youth who screen positive for suicide risk, and provide recommendations on best practices for implementing suicide risk screening in medical settings.

AbstractAlthough the last several years have been marked by significant advances in intervention efforts for youth suicide prevention, suicide remains the second leading cause of death among this age group in the United States. We discuss promising results from intervention research with the goal of informing policies for enhancing suicide prevention care for youth. Additionally, we review findings that denote the critical role of the media and civil legislation on youth suicide prevention.
Rights

AbstractTransnational migration gives rise to multiple forms of potential exploitation of paid domestic work, being an occupation that is relegated to the informal labour market where migrant women often find themselves in powerless positions in relation to their employers and host society. This is especially so when they are undocumented migrants, as is the case for migrants who do not fulfil the requirements for labour or family migration. As a consequence, in many countries, migrants’ employment in private households is strongly deregulated and workers do not have access to social and labour protection (Triandafyllidou & Marchetti, 2017). In several countries, domestic work is not recognized as work, and is therefore excluded from labour protections. Domestic workers are often deprived of monetary payment and compensated with only food and shelter. Also, in countries where domestic work is regulated through labour laws, provisions differ significantly from those in place for other jobs, having lower remuneration and fewer social protections. This lack of a normative framework adds to the vulnerability that is typical of the sector due to the isolation that is characteristic of this kind of work (especially for live-in workers) and the social stigmatization that they face in different parts of the world.
Conclusion
Authors: Marchetti Sabrina 
Published: August 2022

AbstractI hope that readers of this book will have found in it a complete and inspiring overview of the many issues at stake around the topic of domestic work, from a migratory perspective. Some of the issues discussed in this volume actually go beyond the experience of migrants, in as far as they may concern the non-migrants among domestic workers. But they also concern workers in the care sectors more generally, as well as the households, companies or institutions for which they work.

Published: August 2022

AbstractWe compute the hadronic running of the electromagnetic and weak couplings in lattice QCD withNf= 2 + 1 flavors of$$ \mathcal{O} $$O(a) improved Wilson fermions. Using two different discretizations of the vector current, we compute the quark-connected and –disconnected contributions to the hadronic vacuum polarization (HVP) functions$$ \overline{\varPi} $$Π¯γγand$$ \overline{\varPi} $$Π¯γZfor Euclidean squared momentaQ2≤ 7 GeV2. Gauge field ensembles at four values of the lattice spacing and several values of the pion mass, including its physical value, are used to extrapolate the results to the physical point. The ability to perform an exact flavor decomposition allows us to present the most precise determination to date of the SU(3)-flavor-suppressed HVP function$$ \overline{\varPi} $$Π¯08that enters the running of sin2θW. Our results for$$ \overline{\varPi} $$Π¯γγ,$$ \overline{\varPi} $$Π¯γZand$$ \overline{\varPi} $$Π¯08are presented in terms of rational functions for continuous values ofQ2below 7 GeV2. We observe a tension of up to 3.5 standard deviation between our lattice results for$$ \Delta {\alpha}_{\mathrm{had}}^{(5)} $$∆αhad5(−Q2) and estimates based on theR-ratio for space-like momenta in the range 3–7 GeV2. The tension is, however, strongly diminished when translating our result to theZpole, by employing the Euclidean split technique and perturbative QCD, which yields$$ \Delta {\alpha}_{\mathrm{had}}^{(5)}\left({M}_Z^2\right) $$∆αhad5MZ2= 0.02773(15) and agrees with results based on theR-ratio within the quoted uncertainties.
The collider landscape: which collider for establishing the SM instability?
Authors: Franceschini Roberto , Strumia Alessandro , Wulzer Andrea 
Published: August 2022

AbstractCapabilities of future colliders are usually discussed assuming specific hypothetical new physics. We consider the opposite possibility: that no new physics is accessible, and we want to learn if the unnatural Standard Model is part of a vast landscape. We argue that a main step in this direction would be establishing the possible instability scale of the Higgs potential. This primarily needs reducing the uncertainty on the strong coupling and on the top quark mass. We show that the top quark mass can be measured well enough via a$$ t\overline{t} $$tt¯threshold scan with low 1033cm−2sec−1luminosity, that seems achievable at a ‘small’e+e−collider in the LEP tunnel, or at a muon collider demonstrator.
Global weak solutions for the Landau–Lifshitz–Gilbert–Vlasov–Maxwell system coupled via emergent electromagnetic fields
Authors: Dorešić Tvrtko , Melcher Christof 
Published: August 2022

AbstractMotivated by recent models of current driven magnetization dynamics, we examine the coupling of the Landau–Lifshitz–Gilbert equation and classical electron transport governed by the Vlasov–Maxwell system. The interaction is based on space-time gyro-coupling in the form of emergent electromagnetic fields of quantized helicity that add up to the conventional Maxwell fields. We construct global weak solutions of the coupled system in the framework of frustrated magnets with competing first- and second-order gradient interactions known to host topological solitons such as magnetic skyrmions and hopfions.

Abstract
Introduction and hypothesis
International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS) is a simple and effective questionnaire for evaluating vaginal symptoms, sexual problems and the quality of life (QOL) in patients. This study was aimed at validating the simplified Chinese version of the ICIQ-VS.

Methods
A total of 120 women with pelvic organ prolapse (POP) stage <2, 124 with stage ≥ 2, and 51 patients who underwent POP surgery (POP stage ≥2) were included. Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC) were used for reliability analysis. We used the content validity index, Kruskal–Wallis H test, and Mann–Whitney U test to study validity. Paired sample t test, Wilcoxon signed-rank test, effect size and standardized response mean were used to assess sensitivity.

Results
The Cronbach’s alpha coefficients of the vaginal symptoms score (VSS) and sexual matters score (SMS) were 0.787 and 0.861 respectively. The test–retest reliabilities of the VSS, SMS, and QOL score were 0.830, 0.894, and 0.948 respectively. The test–retest reliability was from good to excellent (ICC 0.669–0.948). The item-level content validity index was 0.60 to 1.00. The scale-level content validity index/universal agreement was 0.95, and the scale-level content validity index/average was 0.96. Significant score differences existed between the symptomatic and asymptomatic groups (p < 0.001). Criterion validity was significant (p < 0.001). VSS and QOL score had high sensitivity (p < 0.001, effect size and standardized response mean >0.8).

Conclusions
The simplified Chinese version of the ICIQ-VS can objectively and reliably access vaginal symptoms, sexual matters, and QOL in Chinese women.

Published: August 2022

Abstract
Introduction and objectives
This Swiss LithoClast® Trilogy lithotrite is a new lithotrite for percutaneous nephrolithotomy (PCNL). It has four modifiable settings; impact, frequency, ultrasound and suction. We aim to determine the optimal device settings for the fastest stone clearance.

Materials and methods
Kidney stone phantoms were made with Begostone in a powder to water ratio (15:3–15:6). Complete stone clearance (seconds) was calculated and impact and frequency were adjusted and repeated N = 3. Intra renal pressure (IRP) was then measured in a porcine kidney model.

Results
Stone phantoms with physical properties similar to struvite were cleared best with 100% impact and frequency of 12 Hz. Both uric acid stone phantoms and calcium phosphate stone phantoms were cleared most efficiently with an impact of 30% and a frequency of 4 Hz. The mean time to clear uric acid stone phantoms was 83 s versus 217 s for calcium phosphate stone phantoms. Similarly, for calcium oxalate stone phantoms, an impact of 30% and a frequency of 4 Hz was associated with the fastest clearance time, mean 204 s. However, the differences between 4, 8 and 12 Hz were not statistically significant. At a suction level of 60% or higher, IRP became negative.

Conclusion
These results indicate that stone phantoms of hard kidney stones are cleared more efficiently at lower impact and frequency settings. With regard to suction, a setting of ≤ 50% appears to be the optimal setting.
Influence of implantation of a total hip endoprosthesis on the ipsilateral leg alignment: the effect of sex and dysplasia of the hip
Authors: van Drongelen Stefan , Fey Benjamin , Stief Felix , Meurer Andrea 
Published: August 2022

Abstract
Introduction
Differences in leg and hip morphology exist between sexes and developmental hip dysplasia is known to alter proximal femoral morphology. The purpose of this study was to determine whether existing differences in leg alignment due to sex or developmental hip dysplasia have an effect on changes in leg alignment after total hip arthroplasty.

Materials and methods
30 hip osteoarthritis patients underwent biplanar full-length radiography in the standing position preoperatively and 3 months after total hip arthroplasty. Differences in leg alignment between men and women and between patients with primary hip osteoarthritis and patients with developmental dysplasia before and after surgery were tested using a general linear model for repeated measures.

Results
Implantation of a hip prosthesis had no differential effect on ipsilateral leg alignment in patients with hip osteoarthritis due to dysplasia and in patients with primary hip osteoarthritis. However, patients with hip osteoarthritis due to dysplasia had a 2.1° higher valgus both before and after surgery. After total hip arthroplasty, women had a significantly greater increase in varus angle (1.6° vs. 0°) and femoral offset (10.5 vs. 4.6 mm) compared with men. Because the change in acetabular offset was smaller (2.2 vs. 6.2 mm), the global femoral offset was only increased in women. Femoral torsion was constant for men (15.0° and 16.5°), whereas femoral torsion was significantly reduced in women (19.9° and 13.2°).

Conclusions
Hip arthroplasty has a greater effect on leg axis in women than in men. The axial leg alignment of women could change from a natural valgus to a varus alignment. Therefore, surgeons should consider the effects of total hip arthroplasty on leg alignment in patients with hip osteoarthritis. Whether these changes in leg alignment are also clinically relevant and lead to premature medial or lateral knee osteoarthritis should be investigated in future work.

Needs assessment for patient-centered education and outcome metrics in robotic surgery
Authors: Moore Hope Nicole , de Paula Thais Reif , Keller Deborah S. 
Published: August 2022

Abstract
Background
From clinical experience, many patients undergoing robotic assisted surgery (RAS) have a poor understanding of the technology. To ensure informed consent and appropriate expectations, a needs assessment for patient-centered education and outcome metrics in RAS is warranted. Our goal was to perform an assessment of patient understanding, comfort with robotic technology, and ability to obtain critical information from their surgeon when undergoing RAS.

Methods
Twenty patients planned for RAS by three surgeons were asked to complete a six-item Likert agreement scale survey prior to signing informed consent. The study coordinator administered surveys, while the surgeon left the room. Indicator statements were crafted to reduce bias and two-way evaluated for consistency. The surgeons were additionally asked their perception of each patient’s understanding and comfort with RAS. Frequency statistics and tendencies were analyzed.

Results
Surgeons strongly agreed all patients appropriately understood how RAS functioned and would ask more questions before signing consent, if needed. Patients were predominately not familiar with RAS and felt surgeons did not explain how RAS worked. There was wide variability on if patients understood how RAS worked for their treatment. Overall, patients were not completely comfortable with RAS for their care, did not understand the risks of RAS compared to other approaches, and did not feel their surgeon understood what they needed to know to make informed decisions.

Conclusions
This needs assessment demonstrated critical gaps in patient knowledge about RAS, surgeon communication skills, and the ability of surgeons to know what was important from the patient perspective. The development of RAS patient-centered education and outcome metrics could help address these gaps.
