Guarding the central venous access device: a new solution for an old problem
Authors: Doellman Darcy 
Published: October 2023

HIGHLIGHTS CLABSIs are a major concern in both the adult and pediatric patient population. Contamination of catheter hubs is a common cause of CLABSI. A novel, transparent line guard protects CVAD hubs from gross contamination. Central line-associated blood stream infections (CLABSIs) are a serious and potentially deadly complication in patients with a central venous access device (CVAD). CVADs play an essential role in modern medicine, serving as lifelines for many patients. To maintain safe and stable venous access, infection prevention bundles are used to help protect patients from complications such as CLABSI. Despite most CLABSIs being preventable, rates have been on the rise, often disproportionately impacting critically ill children. New solutions are needed to strengthen infection prevention bundles and protect CVADs from pathogen entry at catheter hubs and line connections. A novel, Food and Drug Administration–listed device has become available recently to guard CVADs from sources of gross contamination, addressing this apparent gap in infection prevention technology and practice.

Published: October 2023

We describe a free-space optical communications system operating with an externally modulated infrared carrier signal at 1550 nm. The purpose of the system is to explore an alternative to radio-frequency wireless communications, which are subject to spectral congestion and bandwidth limitations. We provide details of the optical alignment procedure and a means for extrapolating the obtained results to larger transmission distances. To illustrate the versatility of the system, a relatively wideband signal was chosen for transmission: an NTSC analog video signal, whose instantaneous bandwidth was 6 MHz. We describe the performance of the system by examining its output image quality and signal-to-noise ratio.
Fifty years of evidence on perinatal experience among refugee and asylum-seeking women in Organization for Economic Co-operation and Development (OECD) countries: A scoping review
Authors: Ramadan Marwa , Rukh-E-Qamar Hani , Yang Seungmi , Vang Zoua M. 
Published: October 2023

Background
Members of the Organization for Economic Co-operation and Development (OECD) play a significant role in hosting and supporting refugees. Refugees and asylum seekers in OECD countries may face unique challenges in accessing perinatal healthcare. These challenges can impact their use of and experience with perinatal health services leading to poor maternal and infant outcomes. This scoping review describes the general trends in perinatal health research among refugees/asylum seekers in OECD countries over the past fifty years (1970 to 2021) as well as summarizes their perinatal experience.

Methods
Databases including Embase and Medline were searched using relevant key words for "refugee/ asylum seeker", "perinatal ", and " OECD countries.". Articles were excluded if they only involved economic migrants or internally displaced persons, conducted in non-OECD countries, only assessed health behaviors and practices during pregnancy (e.g., smoking), or were published in a language other than English. The final list of articles included 82 unique studies.

Results
In the 40 years between 1970 and 2009, very few studies (n = 9) examined perinatal health among refugees/ asylum seekers in OECD countries. However, an increasing trend was observed over the past decade. Early studies (1980 to 2009) focused more on traditional perinatal outcomes; however, from 2010 onwards, studies related to perinatal experience were more likely to emerge in the global health literature. Access to timely prenatal care remains a challenge with failure to address the root causes of the problem in several OECD countries including those with a long history of hosting refugees. The limited availability of interpretation services and the lack of a patient-centered approach to care have also interfered with the perceived quality of care. In addition, perceived isolation and the limited social support experienced by this vulnerable population have negatively impacted their perinatal experiences in several OECD countries.

Conclusion
Refugee/asylum seekers in OECD countries face a number of challenges during the perinatal period. Policy changes and further research are needed to address access barriers and identify specific interventions that can improve their well-being during this critical period.
Association between gestational weight gain and adverse neonatal outcomes in women conceiving with assisted reproductive technology: Evidence from the NVSS 2019–2021
Authors: Jiang Feifei , Li Yanan , Sun Lipeng 
Published: October 2023

Objective
To evaluate the association between gestational weight gain (GWG) and adverse neonatal outcomes in women who conceived using assisted reproductive technology (ART).

Methods
The National Vital Statistics System (NVSS) 2019–2021 provided data for this retrospective cohort study. Adverse neonatal outcomes included premature birth, small for gestational age (SGA), large for gestational age (LGA), macrosomia, low birth weight (LBW), and other abnormal conditions. Any adverse outcome was defined as at least one of the above six outcomes. Multivariate logistic regression analysis was employed to evaluate the associations between GWG and different outcomes, after adjusting for confounding factors. These associations were further assessed in subgroups of maternal age at delivery, paternal age at delivery, preconception body mass index (BMI), gestational age, maternal race, parity, gestational diabetes, and gestational hypertension.

Results
Totally 108201 women were included, with 22282 in the insufficient GWG group, 38034 in the sufficient GWG group, and 47885 in the excessive GWG group. Women with insufficient GWG [odds ratios (OR) = 1.11, 95%CI: 1.07–1.16, P<0.001] and excessive GWG (OR = 1.14, 95%CI: 1.10–1.18, P<0.001) had significantly greater risks of any adverse outcome than those with sufficient GWG. In contrast to sufficient GWG, insufficient GWG was associated with significantly elevated risks of premature birth (OR = 1.42, 95%CI: 1.35–1.48, P<0.001), SGA (OR = 1.45, 95%CI: 1.37–1.53, P<0.001), LBW (OR = 1.47, 95%CI: 1.37–1.58, P<0.001), and other abnormal conditions (OR = 1.32, 95%CI: 1.27–1.39, P<0.001), and excessive GWG was associated with significantly lower risks of premature birth (OR = 0.86, 95%CI: 0.83–0.90, P<0.001), SGA (OR = 0.79, 95%CI: 0.75–0.83, P<0.001), LBW (OR = 0.85, 95%CI: 0.79–0.91, P<0.001), and other abnormal conditions (OR = 0.92, 95%CI: 0.88–0.96, P<0.001). Infants born to women with insufficient GWG had significantly decreased risks of LGA (OR = 0.71, 95%CI: 0.66–0.75, P<0.001) and macrosomia (OR = 0.68, 95%CI: 0.63–0.74, P<0.001), and infants born to women with excessive GWG had significantly increased risks of LGA (OR = 1.50, 95%CI: 1.44–1.56, P<0.001) and macrosomia (OR = 1.60, 95%CI: 1.51–1.69, P<0.001).

Conclusion
Insufficient GWG and excessive GWG were associated with increased risks of any adverse outcome than sufficient GWG in women who conceived with ART, indicating the applicability of recommended GWG by the Institute of Medicine (IOM) in this population.
The data quality and applicability of a Danish prehospital electronic health record: A mixed-methods study
Authors: Kjær Jeannett , Milling Louise , Wittrock Daniel , Nielsen Lars Bak , Mikkelsen Søren 
Published: October 2023

Background
Without accurate documentation, it can be difficult to assess the quality of care and the impact of quality improvement initiatives. Prehospital lack of documentation of the basic measurements is associated with a twofold risk of mortality. The aim of this study was to investigate data quality in the electronic prehospital patient record (ePPR) system in the Region of Southern Denmark. In addition, we investigated ambulance professionals’ attitudes toward the use of ePPR and identified barriers and facilitators to its use.

Method
We used an explanatory sequential mixed-methods design. Phase one consisted of a retrospective assessment of the data quality of ePPR information, and phase two included semi-structured interviews with ambulance professionals combined with observations. We included patients who were acutely transported to an emergency department by ambulance in the Region of Southern Denmark from 2016 to 2020. Data completeness was calculated for each vital sign using a two-way table of frequency. Vital signs were summarised to calculate data correctness. Interviews and observations were analysed using thematic analysis.

Results
Overall, an improvement in data completeness and correctness was observed from 2016–2020. When stratified by age group, children (<12 years) accounted for the majority of missing vital sign registrations. In the thematic analysis, we identified four themes; ambulance professionals’ attitudes, emergency setting, training and guidelines, and tablet and software.

Conclusion
We found high data quality, but there is room for improvement. The ambulance professionals’ attitudes toward the ePPR, working in an emergency setting, a notion of insufficient training in completing the ePPR, and challenges related to the tablet and software could be barriers to data completeness and correctness. It would be beneficial to include the end-user when developing an ePPR system and to consider that the tablet should be used in emergency situations.

Authors: Romero Duque David 
Published: October 2023

La siguiente reflexión corresponde a un avance de mi proyecto de maestría que hasta ahora se titula Mirada, Empatía y Tejido de Movimiento. Cámara inter/subjetiva y empatía kinestésica: el registro de prácticas artísticas para la conformación de narrativas aumentadas, donde propongo el registro de acontecimientos y corporalidades a través de la mirada en las prácticas artísticas partiendo desde un entregar la cámara —dispuestas en la cabeza o pecho de quienes desean registrar(se)— para captar el punto de vista del otro, es decir, implementando cámaras subjetivas para convertirse en un archivo evocador de sentidos de esas experiencias corporales que, configurados desde las posibilidades de las narrativas aumentadas, nos permita aprender/sentir a partir de una posible empatía kinestésica. En un primer momento, busco reflexionar sobre la cámara subjetiva como estrategia de registro en las prácticas artísticas exponiendo las implicaciones éticas que me inquietan en este proceso para así ampliar este concepto a partir del cine. Posteriormente describo uno de los resultados creativos a partir del archivo generado en la investigación a través de la exposición que titula Compartir la mirada, realizada en el marco de la clausura del Taller Itinerante de Artes para la Paz 2022, donde describo los dispositivos, momentos involucrados y su disposición en el espacio.

Published: October 2023

Abstrak Seiring dengan berkembangnya teknologi, sistem automasi industri telah mulai mengambil alih sistem konvensional yang selama ini sudah berjalan. Peranan manusia dalam melakukan setting mesin mulai digantikan dengan algoritma untuk menghasilkan produk yang berkualitas baik. Dengan dikendalikan oleh algoritma yang terstruktur, kesalahan manusia (human eror) yang sering mengurangi stabilitas kualitas hasil produksi bisa diminimalkan. Untuk memenuhi target tersebut PT Djarum di Lini Blending 3 Ton Oasis telah mengembangkan sistem kendali mesin baru. Sistem kendali baru yang dikembangkan harus fleksibel, mudah dioperasikan, dan mudah dalam perawatan. Sebagai otak dari sistem kendali menggunakan PLC (Programmable Logic Controller) Siemens S7 300, sedangkan untuk kebutuhan pengawasan dan kendali proses digunakan SCADA (Supervisory Control and Data Acquisition) Wincc Explorer V7.2. Konsep SCADA ini mencakup komunikasi data, manajemen data, pengawasan proses, dan kendali terhadap mesin. Dalam desain sistem automasi ini didasari dengan jaringan komunikasi Industrial Ethernet antarmesin sehingga semua data dari plant dapat dimonitor di dalam SCADA dan disimpan di dalam basisdata. Kata kunci: Djarum Plant Oasis, Lini Blending, Siemens, Indutrial Ethernet, Automasi Abstract Along with the development of technology, industrial automation system start to take over the conventional system that has been running before. Human role to do manual setting to the machine start to take over by algorithm to produce tobacco with a good quality. Because the machine is controlled by algorithm, human error that often influence product quality can be minimized. To reach the target, Blending 3 Ton Line on Djarum OASIS plant had developed machine control system which flexible, easy to operate and maintain. For the brain of the control system, we use S7 300 PLC (Programmable Logic Controller), and for monitoring and operating the machine we use Wincc Explorer V7.2 SCADA (Supervisory Control and Data Acquisition). SCADA concept here covers data communication, data management, process monitoring and operation interface for the machine. On this automation system design base on Industrial Ethernet network which had been developed so that all data from machine can be monitored on SCADA and also can be saved on the database.

A Weierstrass extremal field theory for the fractional Laplacian
Authors: Cabré Xavier , Erneta Iñigo U. , Felipe-Navarro Juan-Carlos 
Published: October 2023

Abstract
In this paper, we extend, for the first time, part of the Weierstrass extremal field theory in the Calculus of Variations to a nonlocal framework.
Our model case is the energy functional for the fractional Laplacian (the Gagliardo–Sobolev seminorm), for which such a theory was still unknown.
We build a null-Lagrangian and a calibration for nonlinear equations involving the fractional Laplacian in the presence of a field of extremals. Thus, our construction assumes the existence of a family of solutions to the Euler–Lagrange equation whose graphs produce a foliation. Then the minimality of each leaf in the foliation follows from the existence of the calibration.
As an application, we show that monotone solutions to fractional semilinear equations are minimizers.
In a forthcoming work, we generalize the theory to a wide class of nonlocal elliptic functionals and give an application to the viscosity theory.

. We also obtain analogous results in the setting of uniformly parabolic and elliptic equations with bounded, measurable, real and symmetric coefficients. These are the first regularity results for vertical maximal functions without convolution structure.

Published: October 2023

Abstract
Using microbial endophytes to produce bioactive compounds is a reliable scientific method. This investigation aimed to use the Acacia plant for isolating an endophytic fungal strain that has a bio-ability to produce a bio-crude extract. This study also encompassed the assessment of the extract’s biological efficacy as an antibacterial and anticancer agent. Samples of the Acacia plant were collected from “Shuaib Huraymila,” in Riyadh, Saudi Arabia. The isolation and identification of fungal endophytes was done, and then, the production of crude extract was performed using the isolated endophytes. The profile gas chromatography-mass spectroscopy of the extract was determined, followed by the assessment of its biological activity against drug-resistant infections and cancer cells through in vitro examination. The findings showed that the fungal endophyte was Alternaria (Alternaria sorghi), according to internal transcribed spacer sequencing and basic local alignment search tool analysis. The minimum inhibitory concentrations of the extract were 9.1 and 4.5 mg/mL for methicillin-resistant Staphylococcus aureus and drug-resistant Candida auris, respectively, and the IC50% values were 46.6 and 23.7 mg/mL for MCF-7 and A549, respectively. The findings showed that this strain had no antagonistic action against Culex pipiens. This study concluded that the fungal endophyte isolated from the Acacia plant has the bio-ability to produce antimicrobial and anticancer agents.

Increased circulating microRNA-21 level as a potential indicator for predicting a higher risk of incident fragility fractures
Authors: Si Zhen-Xing , Zhou Shi-Feng , Shen Zi-Long , Yan Jing-Long 
Published: October 2023

Abstract

Context
As a common disease in the elderly, osteoporosis clearly increases the risk of fractures, leading to higher mortality, but the current markers to estimate the risk of fractures are limited. MicroRNA-21 (miR-21) may play an important role in osteoporosis, but the link of this biomarker with fractures was undetermined.

Objectives
We aimed to investigate the association between miR-21 levels and the presence of fragility fractures.

Methods
A total of 200 patients were recruited and miR-21 was collected from baseline serum. The correlation between miR-21 and the fracture risk assessment tool (FRAX) score was analyzed. The incidence of fragility fractures was presented by Kaplan-Meier analysis, and Cox regression analysis was utilized to evaluate risk factors. The diagnostic value of miR-21 was conducted by the area under curve (AUC).

Results
The FRAX score was significantly associated with miR-21 level (p<0.001). According to the 50th percentile of miR-21 content in the overall distribution, the cumulative incidence of fragility fractures was significantly higher in patients with higher miR-21 levels than those with lower levels (75.4, 95 % CI: 69.0–81.8 vs. 59.2, 95 % CI: 42.1–76.3, p<0.001). The results of the Cox regression analysis showed that the miR-21 level was an independent risk factor linked to the incidence of fracture (p=0.005). The optimal cut-off value of the miR-21 was 6.08, and the AUC for predicting fracture was 0.718 (95 % CI, 0.645–0.790).

Conclusions
This study showed that miR-21 has optimal diagnostic performance in the discrimination of fragility fracture, and the circulating miR-21 level in predicting the risk of fragility fracture may have a certain value.

On the computational modeling of English relative clauses
Authors: Fong Sandiway , Ginsburg Jason 
Published: October 2023

AbstractEven in this era of parameter-heavy statistical modeling requiring large training datasets, we believe explicit symbolic models of grammar have much to offer, especially when it comes to modeling complex syntactic phenomena using a minimal number of parameters. It is the goal of explanatory symbolic models to make explicit a minimal set of features that license phrase structure, and thus, they should be of interest to engineers seeking parameter-efficient language models. Relative clauses have been much studied and have a long history in linguistics. We contribute a feature-driven account of the formation of a variety of basic English relative clauses in the Minimalist Program framework that is precisely defined, descriptively adequate, and computationally feasible in the sense that we have not observed an exponential scaling with the number of heads in the Lexical Array. Following previous work, we assume an analysis involving a uT feature and uRel feature, possibly simultaneously valued. In this article, we show a detailed mechanical implementation of this analysis and describe the structures computed forthat,which, andwho/whomrelatives for standard English.
