Authors: Novita M , Nuvitalia D , Cholifah N , Ogasawara K 
Published: May 2020

AbstractWe investigated the effect of lattice relaxation in the trivalent transition metal ions doped α-Al2O3crystal (α-Al2O3: TM3+). The transition metal ions are Sc3+, Ti3+, V3+, Cr3+, Mn3+, Fe3+, and Co3+. The lattice relaxation effect was considered by comparing two different methods such as Shannon’s crystal radii methods and Cambridge Serial Total Energy Package (CASTEP) methods. In the Shannon’s crystal radii methods, the lattice relaxation effect was estimated as the ratio of the crystal radii of the substituted ion and the replaced ion. On the other hand, in the CASTEP method, the lattice relaxation effect was estimated by geometry optimization. The detail results show that in the case of Shannon’s crystal radii method, the lattice relaxation ratio was ca. 111.0 - 100.5%. Whereas in the case of CASTEP method, the lattice relaxation ratio was ca. 107.8 - 102.1%. However, the lattice relaxation ratio of α-Al2O3: Sc3+, Ti3+, V3+, Cr3+, Mn3+, Fe3+, and Co3+is unique depends on the ion type.

Abstract
The development of human civilization is characterized by the type of material used by society. The rapid development of material engineering and technology produces a variety of advanced materials such as smart materials, natural materials, chemical materials, nanomaterials, advanced materials, and environmentally friendly materials. Ionic Liquids (ILs) have criteria that are expected to be environmentally friendly because of their Green Chemistry (GC). The vocational syllabus needs to be reconstructed to be able to adapt this material technological progress. The purpose of this study was to determine the opinions of lecturers on the adoption of Ionic Liquid material teaching materials in vocational education in an effort to deal with the use of environmentally friendly materials that are indispensable in the industrial field. The subject of the study was taken through a purposive sampling method. There were 5 lecturers in one of the private polytechnics. Data collection through questionnaires is intended to determine the views of lecturers on ionic fluid material teaching materials and analyze the material requirements to be adopted into the vocational curriculum. The investigation results show that the interest and willingness of the lecturer to study and disseminate reached a score of 80%, this means that the lecturer needed the Ionic Liquid material. However, the teacher’s understanding score still needs to be improved, so that it is necessary to design an Ionic Liquid teaching material that is interesting and easy to understand by both lecturers and students. The implications of this study can be used as recommendations in learning to be able to enrich the syllabus by adding Ionic Liquid material teaching material as an indispensable teaching material along with technological advances in industry 4.0.

Abstract
Collisions on vehicles could cause injury to passengers such as being thrown from a passenger room. To prevent this, a vehicle structure was not too strong which called by crashworthiness criteria through maximum impact force. This study was conducted to determine the smallest structural strength through maximum impact force in a square column with 0.8 mm in thickness. The column was given holes with 3 mm in diameter as crush initiators. The hole was arranged in pyramid pattern with different level and begun with 1 hole in the square column. The research used the quasi-static concept experimentally with 30 mm/min in movement speed of actuator. The machine used Universal Testing Machine (UTM) with 200 kN in capacities. The result showed that the pyramid arrangement with the highest level had the greatest maximum impact force 22.124 kN. Comparison of differences between the highest levels with the lowest levels reached 4.86%. While the difference between the highest level with a square column with 1 hole was 14.24%. So that the more holes arranged in a pyramid would reduce the maximum impact force during a collision.

Published: May 2020

Abstract
The Wilkinson Power Divider (WPD) is one of the most common components used in array antenna feeding networks. It is lossless if the output ports are matched, reciprocal, and largely isolated. Many designs and modifications such as multi-section, open circuited stubs, or tapered transmission were proposed to increase the bandwidth of the conventional WPD. In this paper, we will discuss the design of multi-section sum and diff Wilkinson Power Divider for 3-dimensional radar application using CST Studio Suite 2018. The WPD operates at S-Band Frequency, realized in microstrip using substrate Rogers R0-4003C (lossy) with thickness 1.524 mm and relative permittivity 3.55. The simulation and measurement results are met the desired specification, which are less than -20 dB return loss, more than -10 dB insertion loss, less than - 20 dB port isolation, and 180º phase difference.

Authors: MacCalman Michelle , Harper Leia A , Anderson Kristen G 
Published: May 2020

Abstract

Aims
Emerging adulthood (ages 18–25) has been associated with elevated alcohol use, yet little is known regarding gender identity and drinking contexts in this population. Our goals were to examine the effects of perceived gender match on alcohol use decision-making in social settings among emerging adults.

Methods
Participants (N = 135; 64% white, 11 transgender) completed measures of alcohol consumption, alcohol expectancies and motives, and the Collegiate-Simulated Intoxication Digital Elicitation using an established Internet panel. We conducted a series of univariate analyses to examine the relation between perceived gender match and behavioral willingness (BW) to accept alcohol in a social context.

Results
Participants identifying as men were significantly more likely to accept offers of alcohol when compared with women. While men and women did not differ in terms of BW when participants perceived a gender-matched actor making the offer, when there was a gender mismatch, women had significantly lower BW when compared with men. Though transgender participants were more likely to endorse hazardous drinking behaviors, there were no observable effects of transgender identity on BW.

Conclusion
In this sample, we found that men have a higher BW for alcohol than women and that trans identified persons are at increased risk for alcohol misuse. These findings support the need for more research examining the effect of gender identity on patterns of alcohol use and decision-making in mixed-gender contexts for emerging adults.
What Protects Those at High Risk from Criminal Justice Contact Despite the Odds? A Negative Case Analysis
Authors: Doherty Elaine Eggleston , Bersani Bianca E 
Published: May 2020

AbstractCriminal justice contact is a prevalent, if not expected, life event for many high-risk individuals with deleterious consequences; yet, many individuals at high risk are able to avoid this contact (i.e. negative cases exist). In this study, we draw on the life course framework and utilize negative case analysis to (1) estimate the prevalence of criminal justice avoidance within a sample of structurally high-risk Black men and (2) explore the individual, familial and contextual factors in childhood and adolescence that distinguish these negative cases. One’s own ‘on-time’ and one’s siblings’ education emerge as particularly strong protective factors suggesting that the presence of unique protection, as opposed to the absence of risk, may be most salient. Theoretical implications are discussed.

AbstractTOR1A/TorsinA mutations cause two incurable diseases: a recessive congenital syndrome that can be lethal, and a dominantly-inherited childhood-onset dystonia (DYT-TOR1A). TorsinA has been linked to phosphatidic acid lipid metabolism in Drosophila melanogaster. Here we evaluate the role of phosphatidic acid phosphatase (PAP) enzymes in TOR1A diseases using induced pluripotent stem cell-derived neurons from patients, and mouse models of recessive Tor1a disease. We find that Lipin PAP enzyme activity is abnormally elevated in human DYT-TOR1A dystonia patient cells and in the brains of four different Tor1a mouse models. Its severity also correlated with the dosage of Tor1a/TOR1A mutation. We assessed the role of excess Lipin activity in the neurological dysfunction of Tor1a disease mouse models by interbreeding these with Lpin1 knock-out mice. Genetic reduction of Lpin1 improved the survival of recessive Tor1a disease-model mice, alongside suppressing neurodegeneration, motor dysfunction, and nuclear membrane pathology. These data establish that TOR1A disease mutations cause abnormal phosphatidic acid metabolism, and suggest that approaches that suppress Lipin PAP enzyme activity could be therapeutically useful for TOR1A diseases.

AbstractThe aging process is accompanied by changes in the brain’s cortex at many levels. There is growing interest in summarizing these complex brain-aging profiles into a single, quantitative index that could serve as a biomarker both for characterizing individual brain health and for identifying neurodegenerative and neuropsychiatric diseases. Using a large-scale structural covariance network (SCN)-based framework with machine learning algorithms, we demonstrate this framework’s ability to predict individual brain age in a large sample of middle-to-late age adults, and highlight its clinical specificity for several disease populations from a network perspective. A proposed estimator with 40 SCNs could predict individual brain age, balancing between model complexity and prediction accuracy. Notably, we found that the most significant SCN for predicting brain age included the caudate nucleus, putamen, hippocampus, amygdala, and cerebellar regions. Furthermore, our data indicate a larger brain age disparity in patients with schizophrenia and Alzheimer’s disease than in healthy controls, while this metric did not differ significantly in patients with major depressive disorder. These findings provide empirical evidence supporting the estimation of brain age from a brain network perspective, and demonstrate the clinical feasibility of evaluating neurological diseases hypothesized to be associated with accelerated brain aging.

AbstractBackgroundAs new drugs are developed for multidrug-resistant tuberculosis (MDR-TB), the role of currently used drugs must be reevaluated.MethodsWe combined individual-level data on patients with pulmonary MDR-TB published during 2009–2016 from 25 countries. We compared patients receiving each of the injectable drugs and those receiving no injectable drugs. Analyses were based on patients whose isolates were susceptible to the drug they received. Using random-effects logistic regression with propensity score matching, we estimated the effect of each agent in terms of standardized treatment outcomes.ResultsMore patients received kanamycin (n = 4330) and capreomycin (n = 2401) than amikacin (n = 2275) or streptomycin (n = 1554), opposite to their apparent effectiveness. Compared with kanamycin, amikacin was associated with 6 more cures per 100 patients (95% confidence interval [CI], 4–8), while streptomycin was associated with 7 (95% CI, 5–8) more cures and 5 (95% CI, 4–7) fewer deaths per 100 patients. Compared with capreomycin, amikacin was associated with 9 (95% CI, 6–11) more cures and 5 (95% CI, 2–8) fewer deaths per 100 patients, while streptomycin was associated with 10 (95% CI, 8–13) more cures and 10 (95% CI, 7–12) fewer deaths per 100 patients treated. In contrast to amikacin and streptomycin, patients treated with kanamycin or capreomycin did not fare better than patients treated with no injectable drugs.ConclusionsWhen aminoglycosides are used to treat MDR-TB and drug susceptibility test results support their use, streptomycin and amikacin, not kanamycin or capreomycin, are the drugs of choice.

Abstract

Background
Respiratory syncytial virus (RSV) is a leading cause of viral pneumonia and bronchiolitis during the first 6 months of life. Placentally transferred antibodies can prevent severe RSV illness, and maternal immunization may reduce illness in young infants. Identification of protective antibody levels facilitates the advancement of vaccine candidates and maternal immunization.

Methods
We conducted a nested case-control study with 587 Malian mother–infant pairs, followed from birth to age 6 months. RSV cases were infants who developed influenza-like illness (ILI) or pneumonia and were RSV-positive by polymerase chain reaction. Cases were matched to healthy controls and RSV-negative ILI controls. RSV-A and RSV-B neutralizing antibodies were measured in maternal, cord blood, and infant sera at age 3 and 6 months.

Results
Maternal antibodies were efficiently transferred to infants. Maternal and infant RSV titers were strongly correlated. Infant antibody titers against RSV-A were 3 times higher than those against RSV-B. At birth, infants who remained healthy had significantly higher RSV-A and RSV-B titers compared with infants who subsequently contracted RSV. RSV-A inhibitory concentration (IC)80 titer &gt;239 or RSV-B titer &gt;60 at birth was significantly associated with being a healthy control compared with an RSV case within the first 3 months of life. RSV-A IC80 titers in cord blood were associated with decreased episodes of pneumonia.

Conclusions
Maternally acquired RSV antibodies were associated with protection of infants against community-detected cases of RSV-ILI and pneumonia. RSV titers in cord blood can predict whether an infant will be infected with RSV or remain uninfected.

Abstract

Background
Penicillin allergies are associated with inferior patient and antimicrobial stewardship outcomes. We implemented a whole-of-hospital program to assess the efficacy of inpatient delabeling for low-risk penicillin allergies in hospitalized inpatients.

Methods
Patients ≥ 18 years of age with a low-risk penicillin allergy were offered a single-dose oral penicillin challenge or direct label removal based on history (direct delabeling). The primary endpoint was the proportion of patients delabeled. Key secondary endpoints were antibiotic utilization pre- (index admission) and post-delabeling (index admission and 90 days).

Results
Between 21 January 2019 and 31 August 2019, we assessed 1791 patients reporting 2315 antibiotic allergies, 1225 with a penicillin allergy. Three hundred fifty-five patients were delabeled: 161 by direct delabeling and 194 via oral penicillin challenge. Ninety-seven percent (194/200) of patients were negative upon oral penicillin challenge. In the delabeled patients, we observed an increase in narrow-spectrum penicillin usage (adjusted odds ratio [OR], 10.51 [95% confidence interval {CI}, 5.39–20.48]), improved appropriate antibiotic prescribing (adjusted OR, 2.13 [95% CI, 1.45–3.13]), and a reduction in restricted antibiotic usage (adjusted OR, 0.38 [95% CI, .27–.54]). In the propensity score analysis, there was an increase in narrow-spectrum penicillins (OR, 10.89 [95% CI, 5.09–23.31]) and β-lactam/β-lactamase inhibitors (OR, 6.68 [95% CI, 3.94–11.35]) and a reduction in restricted antibiotic use (OR, 0.52 [95% CI, .36–.74]) and inappropriate prescriptions (relative risk ratio, 0.43 [95% CI, .26–.72]) in the delabeled group compared with the group who retained their allergy label.

Conclusions
This health services program using a combination of direct delabeling and oral penicillin challenge resulted in significant impacts on the use of preferred antibiotics and appropriate prescribing.

Summary

Introduction
Both cervical (McKeown) and intrathoracic (Ivor Lewis) anastomosis of transthoracic esophagectomy are surgical procedures that can be performed for distal esophageal or gastro-esophageal junction (GEJ) cancer. The purpose of this study was to investigate the long-term health-related quality of life (HR-QoL) after McKeown and Ivor Lewis esophagectomy in a tertiary referral center.

Methods
Disease-free patients &gt;1 year following a McKeown or an Ivor Lewis esophagectomy with a two-field lymphadenectomy for a distal or GEJ carcinoma visiting the outpatient clinic between 2014 and 2018 were asked to complete the EORTC QLQ-C30 and EORTC QLQ-OG25 questionnaires. HR-QoL was investigated in both groups.

Results
A total of 89 patients were included after McKeown and 115 after Ivor Lewis esophagectomy. Median follow-up was 2.4 years (IQR 1.7–3.6). Patients after McKeown esophagectomy reported more problems with ‘eating with others’ compared to patients after Ivor Lewis esophagectomy (mean scores: 49.9 vs. 38.8). This difference was both clinically relevant and significant after correction for multiple testing (β = 11.1, 95% CI 3.105–19.127, P = 0.042). Patients in both groups reported a poorer HR-QoL (≥10 points) than the general population with respect to nausea and vomiting, dyspnea, appetite loss, financial difficulties, problems with eating, reflux, eating with others, choked when swallowing, trouble with coughing, and weight loss.

Conclusion
Long-term HR-QoL of disease-free patients following a McKeown or Ivor Lewis esophagectomy for a distal or GEJ carcinoma is largely comparable. Irrespective of the surgical technique, patients’ HR-QoL following esophagectomy is compromised. When given the choice, patients should be informed that after a McKeown esophagectomy more problems while eating with others can occur.
