Purpose
This study aimed to expand and inform the emerging body of research on the negative experiences of social media use among youths and how youths deal with them, in an Asian setting, using a qualitative approach.

Methods
Data were collected using 11 focus group discussions (FGDs) and 25 semi-structured interviews (SIs) among youths aged 15 to 24 years residing in Singapore who were recruited via purposive sampling. Data were analysed using thematic analysis.

Results
The salient negative effects mentioned by participants include the development of negative reactions and feelings from upward comparisons with others (e.g., others’ achievements and lifestyle), receiving hurtful comments, exposure to controversial content (e.g., political events and social movements), as well as the perpetuation of negative feelings, behaviours, and sentiments (e.g., rumination, unhealthy eating behaviour, and self-harm). Participants also described strategies which they have employed or deemed to be useful in mitigating the negative effects of social media use. These include filtering content and users, taking breaks from social media, cognitive reframing, and self-affirmation, where they identify and change stress-inducing patterns of thinking by setting realistic social, physical, and lifestyle expectations for themselves, and focusing on self-development.

Conclusion
The current results highlight that while youths experience negative effects of social media use, they have high media literacy and have employed strategies that appear to mitigate the negative effects of social media use. The findings can inform various stakeholders involved in helping youths navigate the harms of social media use or provide directions for intervention studies aimed at reducing the harms of social media use.

Background & objectives
Cirrhosis patients with worsening of the liver function are defined as acute decompensation (AD) and those who develop extrahepatic organ failure are defined as acute-on-chronic liver failure (ACLF). Both AD and ACLF have an extremely poor prognosis. However, information regarding prognostic predictors is still lacking in Asian populations. We aimed to identify prognostic factors for 30-day and 90-day mortality in cirrhosis patients who develop AD with or without ACLF.

Methods
We included 9 tertiary hospitals from Thailand in a retrospective observational study enrolling hospitalized cirrhosis patients with AD. ACLF was diagnosed according to the EASL-CLIF criteria, which defined as AD patients who have kidney failure or a combination of at least two non-kidney organ failure. Outcomes were clinical parameters and prognostic scores associated with mortality evaluated at 30 days and 90 days.

Results
Between 2015 and 2020, 602 patients (301 for each group) were included. The 30-day and 90-day mortality rates of ACLF vs. AD were 57.48% vs. 25.50% (p<0.001) and 67.44% vs. 32.78% (p<0.001), respectively. For ACLF patients, logistic regression analysis adjusted for demographic data, and clinical information showed that increasing creatinine was a predictor for 30-day mortality (p = 0.038), while the CLIF-C OF score predicted both 30-day (p = 0.018) and 90-day (p = 0.037) mortalities, achieving the best discriminatory power with AUROCs of 0.705 and 0.709, respectively. For AD patients, none of the parameters was found to be significantly associated with 30-day mortality, while bacterial infection, CLIF-AD score and Child-Turcotte-Pugh score were independent parameters associated with 90-day mortality, with p values of 0.041, 0.024 and 0.024. However, their predictive performance became nonsignificant after adjustment by multivariate regression analysis.

Conclusions
Regarding Thai patients, the CLIF-C OF score was the best predictor for 30-day and 90-day mortalities in ACLF patients, while appropriate prognostic factors for AD patients remained inconclusive.

AbstractThe aim was to assess the association between fetal growth restriction (FGR) and fetal heart rate variability (FHRV) in relation to fetal movements. A prospective observational cohort study was performed. Non‐invasive fetal electrocardiography (NI‐FECG) allowed beat‐to‐beat assessments with <5% corrections of RR intervals. FHRV analyses included: Root mean square of successive RR interval differences (RMSSD), high frequency power (HF power), and low frequency power (LF power). Fetal movements were categorized by continuous ultrasound scanning. We enrolled 36 singleton pregnant women expecting a small fetus (< the 2.3 percentile of mean weight for gestational age) diagnosed by ultrasound, of whom 25 presented with a birthweight < the 2.3 percentile. Among these, 11 were excluded due to low quality NI‐FECG recordings, leaving 14 women with 28 recordings eligible for inclusion in the analyses. The control group consisted of 22 healthy fetuses with birthweights between the 10th and the 90th percentile (average for gestational age [AGA]). In FGR fetuses the HRV response to respiratory activity was comparable to that of AGA fetuses. RMSSD (Ratio 1.54 [95% CI: 1.33; 1.79]) and HF power (Ratio 2.88 [95% CI: 2.12; 3.91]) increased, whereas LF/HF power (Ratio: 0.44 [95% CI: 0.31;0.63]) decreased. However, during fetal quiescence, FGR fetuses differed significantly from AGA fetuses. Compared to AGA fetuses, FGR fetuses displayed lower RMSSD (Ratio 0.77 (95% CI: 0.58; 1.02)) and HF power (Ratio 0.56 (95% CI:0.32; 0.98)). This reduction was associated with the severity of the FGR. In conclusion, FGR fetuses displayed a respiratory sinus arrhythmia (RSA) comparable to AGA fetuses; however, more important, parameters representing cardiac vagal activity were impaired in FGR fetuses during quiescence. RSA may constitute an intrinsic function of the cardiovascular system, which is unaffected by fetal compromise. However, the basic cardiac outflow assessed during fetal quiescence indicates a suppressed cardiac vagal activity in the FGR fetuses.
Economics of Ancient Law: The Laws of Manu on Contracts
Authors: Bose Feler 
Published: November 2022

AbstractAncient law can be analyzed using economic tools. With a renewed interest from the political class to make the ancient Laws of Manu (Manu’sDharmaśāstra) more relevant to modern Indian law, the economic analysis of the Laws of Manu regarding contracts allows us to look at the issue from an efficiency standpoint. The paper will look at both regular contracts and marriage contracts. Surprisingly, many of the ancient laws are like the modern law of contracts especially in areas of contract breach. However, when considering marriage contracts, the bargaining position of men is stronger than women.

Abstract
In order to deal with the shortage of spacecraft telemetry, tracking, and command (TT&C) resources and the high complexity of planning and scheduling in the future, based on the current situation of the TT&C network in China, the construction requirements of space–ground integration TT&C network are put forward, and the basic framework is constructed. Referring to the random access mechanism of ground cellular mobile communication system, access once encountered TT&C mode is designed. This work introduces its basic idea, gives an example of the implementation process in the new form, designs the protocol stack system of random access TT&C, and probes into the key technologies, such as spacecraft access optimization selection strategy and panoramic (airspace) multi-beam and multi-target simultaneous TT&C technology, for reference of further research.

Authors: Rozycki Henry J. , Yitayew Miheret 
Published: November 2022

Abstract

Objectives
To review how the Apgar score is used in published clinical research as well as who uses it, and how this may have changed between 1989–90 and 2018–19.

Methods
Pubmed search for English publications using MeSH Terms “apgar score” OR “apgar” AND “score” AND “humans” for epochs 1989–90 & 2018–19. The location and specialty of first author, primary purpose and how the Apgar score was used was recorded.

Results
There was a 61% increase in number of publications in 2018–19 compared to 1989–90, from all regions except North America. The most common purpose for using the Apgar was to assess newborn status after pregnancy/delivery interventions. There were 50 different definitions of a significant score. Definition of significance was influenced by specialty in 2018–19 and by study purpose in both epochs.

Conclusions
Most studies using the Apgar score are focused on the mother. There is no consistent definition of a significant score. Development of any future newborn assessment tools should account for the multiple purposes for which the Apgar score is used.

Published: November 2022

AbstractObjectivesShone’s complex (SC) is characterized by sequential obstructions of left ventricular (LV) inflow and outflow. It can be associated with poor long-term prognosis when compared to Simple-Aortic Coarctation (S-CoA). We aimed to assess whether the degree of ventricular disproportion and 2D-speckle-tracking echocardiography (2D-STE) could improve the accuracy of prenatal prediction of SC.Methods75 consecutive fetuses were retrospectively enrolled from January 2010 to June 2021. Fetuses were divided into 4 groups (Group 1: SC; Group 2: S-CoA; Group 3: False Positive-Coarctation of the Aorta [FP-CoA]; group 4: controls). Comparisons for echocardiographic measures and myocardial deformation indices were performed. A receiver operating characteristic (ROC) analysis was performed on the MV/TV (mitral valve/tricuspid valve ratio) and LV GLS (global longitudinal strain) values to identify cut-offs to separate group 1 and 2 fetuses.ResultsSC fetuses showed a significant reduction in MV/TV when compared to S-CoA and FP-CoA fetuses (p<0.001). LV GLS in SC fetuses was significantly reduced compared to S-CoA fetuses (−13.3 ± 2.1% vs. −17.0 ± 2.2%, p=0.001). A cut-off value of 0.59 for MV/TV and −15.35% for LV GLS yielded a sensitivity of 76 and 82% and a specificity of 71 and 83% respectively in separating SC vs. S-CoA fetuses.ConclusionsSC fetuses showed a more severe degree of ventricular disproportion and a lower LV GLS compared to S-CoA, FP-CoA and control fetuses. MV/TV and GLS are both predictors of SC. These findings may improve the quality of prenatal parental counselling.
Der Einfluss der Unterbringung im offenen Vollzug auf die Entlassungssituation unter Berücksichtigung statischer und dynamischer Risikofaktoren
Authors: Schüttler Helena , Hahnemann Anna 
Published: November 2022

Zusammenfassung
Der offene Vollzug erleichtert das Übergangsmanagement sowie die Entlassungsvorbereitung und hat einen wesentlichen Einfluss auf die Wiedereingliederungschancen von jugendlichen und erwachsenen Gefangenen. Auch wenn sich einige Studien mit dem Zusammenhang von Vollzugsform und Rückfallgefahr beschäftigt haben, wird die Betrachtung zentraler Indikatoren zur Wiedereingliederung (u. a. Tätigkeit, Wohnraum, sozialer Empfangsraum, Finanzen, Lockerungen und vorzeitige Entlassung) oftmals vernachlässigt. Im vorliegenden Beitrag steht daher die Frage im Fokus, wie sich die Entlassungssituation bei 341 jugendlichen und erwachsenen Inhaftierten aus dem offenen und geschlossenen Vollzug gestaltet und welchen Einfluss die Vollzugsform auf diese Situation nimmt. Die Entlassungssituation wird durch die benannten Indikatoren der Wiedereingliederung, die auch im Übergangsmanagement zentral sind, gekennzeichnet.
Da Gefangene im offenen Vollzug eine kriminalprognostisch eher günstige Klientel darstellen und entsprechenden Selektionskriterien unterliegen, ist eine Vergleichbarkeit zu Personen im geschlossenen Vollzug erschwert. Aus diesem Grund werden statische und dynamische Risikofaktoren nach Andrews und Bonta (2010) als Kontrollvariablen in die Auswertung eingebunden. Der Einfluss von Vollzugsform und Risikofaktoren auf die Entlassungssituation wird durch lineare Regressionsanalysen geprüft. Die Ergebnisse zeigen, dass die Entlassungssituation sowohl im Jugend- als auch im Erwachsenenvollzug in der offenen Abteilung positiver zu bewerten ist als im geschlossenen Äquivalent und ein signifikanter Zusammenhang bestätigt werden kann. Dabei weisen die Ergebnisse auf die positiven Effekte des offenen Vollzuges hin. Da eine umfassende Entlassungsvorbereitung aber zeitintensiv ist, plädiert der Beitrag für eine nachhaltige Planung aller wesentlichen Aspekte der Entlassung sowie für eine frühzeitige Verlegung in den offenen Vollzug, um diese umzusetzen.

Published: November 2022

AbstractProduktionen müssen sich immer kürzeren Produktionszyklen, hohen Nachfrageschwankungen und häufigeren Produktwechseln stellen. Dies erfordert, dass Produktionsanlagen agil und modular gestaltet sein müssen, damit der Aufwand für die Rekonfiguration des Systems möglichst gering ist. Im folgenden Beitrag wird das Konzept für eine automatisierte Rekonfiguration einer Produktion mit einem modularen Layout dargestellt. Die prototypische Umsetzung dieses Konzeptes erfolgt in der smartfactory@tugraz.

Published: November 2022

Aim: The aim is to evaluate the pregnancy outcomes of patients with uterus unicornis for 5-year experience in a tertiary center.
Material & Method: Twenty patients with uterus unicornis who were diagnosed with hysterosalpingography and/or 3D TVUSG between 2017 and 2021 and then confirmed with laparoscopy and simultaneous hysteroscopy were recruited for this retrospective study. The reproductive outcome and obstetric complications of the patients were followed up for two years postoperative period.
Results: Overall 20 patients who fulfilled the inclusion criterion were recruited for the study. The mean age was 28.65±5.03 years. Thirteen patients (65%) had primary infertility while the remaining seven had secondary infertility with two of them having a previous ectopic pregnancy. Rudimentary communicating uterine horn was observed in 7 (35%) of the patients. The horns were excised during laparoscopy. Overall, 14 (70%) pregnancies were achieved during the 2 years follow-up period. Twelve (85.7%) patients had a live birth, (71.4% term delivery, 21.4% preterm delivery), and two had a first-trimester spontaneous abortion (15.3%). Six (50%) of 12 patients who had a live birth received tocolytics for preterm labor.
Conclusion: Unicorn uterus is a rare anomaly diagnosed mostly during infertility work-out and might be related to the poor obstetric outcome, but early diagnosis is important for successful pregnancy results for preterm delivery especially in the secondary infertile group. In addition, rudimentary horn excision is recommended due to the high risk of obstetric complications.

Background. Simulation as a proxy tool for conditional clinical training became a powerful technique for introducing trainees to the ultrasound imaging world, allowing them to become a trained sonographer taking into consideration different rates of progress completing a specific task against the time and ensuring the long-lasting maintenance of the obtaining practical skills. Adding a costly, but effective high-fidelity simulator to the residency program justified the expense, demonstrating efficiency of training for improving the clinical performance and confidence of trainees.
Materials and methods. A pilot study in Riga Maternity Hospital within the framework of the study “Role of metabolome, biomarkers and ultrasound parameters in successful labour induction” (Fundamental and Applied Research Programme lzp-2021/1-0300) was performed between March 1st 2022 and 31st April 2022. A virtual-reality simulator (Scantrainer, MedaphorTM, Cardiff, UK) was used with the teaching module for assessment of the uterine cervix. Five trainees in obstetrics and two young specialists included in the study. None of them had Fetal Medicine Foundation certificate of competence in the assessment of the uterine cervical lenght before. The time used on the simulator, the number of simulations and a mean confidence in cervical length assessment before and after simulation were recorded.
Results. The study on assesment of uterine cervical lenght demonstrated statistically significant increase in confidence (p=0.008) and statistically significant decrease in time needed to complete correctly the same tasks for the trainees (p=0.008) that shows a positive learning curve over the time of training on ScanTrainer, Medaphor.
Conclusions. The simple task allows to become a certified specialist in uterine cervical assessment in the short period of time. That support the productiveness of the simulation-based education. The training program should be updated taking into consideration simulation curriculum.

Published: November 2022

Introducción. El frijol común (Phaseolus vulgaris L.) y el maní (Arachis hypogaea L.) son leguminosas consumidas en países en vías de desarrollo. Sin embargo, estos granos pueden estar contaminados con Aspergillus, un género de hongo que incluye especies productoras de micotoxinas. Objetivo. Identificar las especies de Aspergillus que colonizan los granos de frijol y maní en Costa Rica e identificar cepas atoxigénicas de A. flavus. Materiales y métodos. Se recolectaron 83 muestras de granos de frijol común y 19 muestras de maní durante los años 2019 y 2020, en regiones productoras de estos cultivos en Costa Rica. El total de muestras se utilizaron para aislar e identificar las especies de Aspergillus, mediante secuenciación parcial de los genes ITS (espaciador transcrito interno) y cmd (calmodulina). También se identificaron cepas atoxigénicas de A. flavus por métodos químicos y moleculares. Resultados. Un 46 % y 32 % de las muestras recolectadas de frijol y maní, respectivamente, presentaron contaminación con Aspergillus spp. Se obtuvieron 85 aislamientos de Aspergillus en frijol, la mayoría pertenecientes a las especies A. flavus y A. niger. La mayor parte de los aislamientos de A. flavus se recuperaron de las variedades de frijol Cabécar (quince aislamientos) y Nambí (siete aislamientos), mientras que A. niger se aisló, en su mayoría, de la variedad Cabécar (once aislamientos). En el caso del maní, se obtuvieron trece aislamientos, la mayoría de ellos identificados como A. niger. No se encontraron cepas atoxigénicas en maní, sin embargo, en frijol se encontraron cinco cepas de A. flavus con esta característica. Conclusiones. El presente estudio demostró la diversidad de especies de Aspergillus que colonizan los granos de frijoles y maní en Costa Rica. La mayoría de las especies aisladas son productoras de micotoxinas que causan efectos adversos en la salud humana.
PrevDistro: An open-access dataset of Hungarian preverb constructions
Authors: Kalivoda Ágnes 
Published: November 2022

AbstractHungarian has a prolific system of complex predicate formation combining a separable preverb and a verb. These combinations can enter a wide range of constructions, with the preverb preserving its separability to some extent, depending on the construction in question. The primary concern of this paper is to advance the investigation of these phenomena by presenting PrevDistro (Preverb Distributions), an open-access dataset containing more than 41.5 million corpus occurrences of 49 preverb construction types. The paper gives a detailed introduction to PrevDistro, including design considerations, methodology and the resulting dataset's main characteristics.
