Published: February 2023

Abstract
There are many relational data in edge computing They belong tonon-Euclidean spatial data. Graphical neural network can expand edgecomputing capabilities to extract features from non-Euclidean spatialdata, and thus is suitable for edge computing data classification and filtering. In IoT edge computing, there are many computing nodes anddata to be transmitted. Therefore, how to transmit the most needed datato the computing nodes is an important issue, and a better recommendation model is needed to filter t he e dge d ata. L ightGCN i s a superiorrecommendation model based on graph neural network, but there is stilla problem of over-smoothing when the user-item relationship extractionlayer is stacked with multiple layers. To solve this problem, this paperproposes an improved graph neural network collaborative filtering algorithm for edge computing (ECCF) to build a deeper graph neural networkto achieve better feature extraction, keep the purity of local features,and improve recommendation performance. ECCF uses hard negativemining method as a sampling method to improve recommendation accuracy and training efficiency, and uses IndRNN with long and short-termmemory with self-attention layer to capture valid information.The experimental results of the model using Gowalla, Yelp 2018 and AmazonBook show that ECCF performs better in NDCG and Recall evaluationmetrics than LightGCN, IMP-GCN and NGCF. ECCF improves the recommendation accuracy while minimizing the complexity of the model,which is well adapted to be applied to data filtering for edge computing.

Abstract
Background：Retinopathy of prematurity (ROP) is one of the leading causes of babies’ visual impairment and blindness. There is no effective intervention with ROP so far, and thus a deeper understanding of oxygen-induced metabolism may offer novel potential therapeutic approaches to ROP. The aim of this study is to explore a correlation of oxygen-induced renal metabolism with those in eyes and blood from ROP patients or a mouse model of oxygen-induced retinopathy (OIR).
Methods：At postnatal day 7 (P7), 30 healthy C57BL6/J mice were randomly selected and divided into two groups, an OIR group and a WT group. The R-OIR group (N = 8) and R-WT group (N = 8) were examined for renal untargeted metabolomics; Targeted metabolomics analysis was performed to detect vitreous in V-OIR group (N = 7) and V-WT group (N = 7). Network association analysis was performed with the above results and previous studies: retinal-targeted metabolomics of OIR and human blood-targeted metabolomics of ROP.
Results：The levels of metabolites in the R-OIR group were slightly higher than those in the R-WT group, especially in lipids. However, nucleotides of the R-OIR group were lower than the R-WT group. There were 9 canonical signaling pathways enriched, in which the initiation and progression of pathologic retinal neovascularization were closely associated with purine metabolism, arginine biosynthesis, histidine metabolism, pantothenate and CoA biosynthesis, alanine, aspartate and glutamate metabolism; arginine and proline metabolism, tryptophan metabolism, beta-Alanine metabolism, and D-glutamine as well as D-glutamate metabolism. In addition, L-histidinol, Isoguanosine, guanosine, guanine, nicotyrine, quinoxaline-2-carboxylic acid, L-3-hydroxykynurenine, N-gamma-glutamyl-S-propylcysteine, alanine, adenosine diphosphate, and ribose were potential biomarkers of ROP.
Conclusion：Shikimic acid and PC(14:1(9Z)/20:2(11Z,14Z)) are highly specific biomarkers of renal metabolomics of OIR. Arginine biosynthesis is the best common pathway of kidney-untargeted OIR metabolomics, vitreous-, and retina-targeted OIR metabolomics, and blood-targeted metabolomics of ROP, indicating that arginine biosynthesis is the common pathway of ROP and neonatal kidney injury.

Abstract

Aquatic mesocosms are complex test systems used within regulatory risk assessment of plant protection products. These model ecosystems allow to capture interactions of multiple species under environmental conditions. They enable assessment of direct and indirect effects of stressors at all trophic levels and impacts on ecosystem functions. Due to the limited ability to test the multitude of potential exposure scenarios, cross-linking aquatic mesocosm studies with virtual mesocosms, i.e. aquatic system models (ASMs), can serve to meet the demand for more environmental realism and ecological relevance in risk assessment. In this study, full control data sets from seven aquatic mesocosm studies conducted at a single test facility under GLP are graphically analysed. Thereby, not only a comprehensive data base but also an insight into the species present, their dynamics over time and variability in unchallenged mesocosms is provided. While consistency in dynamics could be discerned for physical and chemical parameters, variability was evident for several biological endpoints. This variability points to amplification of small differences over time as well as to stochastic processes. The outline of existing gaps and uncertainties in data leads to the estimation of what can be expected to be captured and predicted by ASMs.
Nutritionally Variant Streptococci - Its Clinical Relevance and Treatment
Options: A Mini-Review

Published: February 2023

:
Nutritionally variant streptococci (NVS) were assumed to be nutritional mutants of
the viridans group of streptococci, but they are now considered as other Streptococcus species.
Due to their difficult nature, to date, the detection and treatment of NVS are challenging.

:
This review aims at a compilation of a comprehensive study on literature reporting the
microbiological characteristics of NVS species, their detection, and treatment strategies with an
emphasis on large-scale research experimentations.

:
According to the literature, the classification of these Streptococci has changed several times,
interpreting the scientific literature of Abiotrophia and Granulicatella spp. NVS strains exhibit
pleomorphic cellular morphologies, and they can be distinguished from other streptococci by
their biochemical reactions and molecular tests. They have been isolated from clinical specimens
including pus, synovial fluid, and blood, in addition to their involvement in endocarditis.
Treatment of NVS is challenging due to its difficult nature and the complexity of antimicrobial
susceptibility testing.

:
Early diagnosis is critical for initiating proper therapy and avoiding fatal consequences.
Microbiologists and clinicians ought to be cautious of these isolates, which are easy to overlook
due to their difficult nature and the challenges in retrieving from clinical samples. Hence largescale
research is required to identify additional detection techniques, infrastructure, and
treatment options.
Postawy pielęgniarek wobec nieskutecznej reanimacji z powodu nagłego zatrzymania krążenia
Authors: Pokorniecka Daria 
Published: February 2023

Wstęp. Nagłe zatrzymanie krążenia to według definicji nieoczekiwane ustanie funkcji serca. Cechami charakterystycznymi są: brak reakcji na bodźce, brak wyczuwalnego tętna i bezdech bądź oddech agonalny. Niektóre źródła, za NZK, uznają również znaczne upośledzenie pracy serca. Kluczowe znaczenie w przypadku tego poważnego problemu medycznego ma natychmiastowa i odpowiednia pomoc.
Cel. Głównym celem pracy jest analiza postaw personelu pielęgniarskiego wobec nieskutecznej reanimacji.
Materiał i metody. Przedmiotem badań są postawy pielęgniarek wobec nieskutecznej reanimacji z powodu nagłego zatrzymania krążenia. Dla potrzeb pracy skorzystano z metody sondażu diagnostycznego, autorskiego kwestionariusza ankiety, standaryzowanego kwestionariusza Mini COPE oraz metod statystycznych.
Wyniki. Analiza zebranych danych dała wyniki ukazujące postawy wobec nieskutecznej reanimacji. Nie potwierdzono istotnej zależności pomiędzy wiekiem, stażem pracy, wykształceniem i płcią a postawą prezentowaną przez badanych. Nie potwierdzono również hipotezy o najczęstszym występowaniu postawy poszukiwania wsparcia w sytuacji stresowej jaką jest nieskuteczna reanimacja. W badaniu strategia aktywnego radzenia sobie i akceptacji była dominująca.
Wnioski. Spośród wszystkich postaw reprezentowanych przez personel pielęgniarski wobec nieskutecznej reanimacji dominującą była postawa aktywnego radzenia sobie. Ponieważ badania dowodzą, że wiek, wykształcenie, czy staż pracy nie wpływają istotnie na sposób radzenia sobie ze stresem wynikłym z nieskutecznej reanimacji, powstaje realna potrzeba pogłębienia zagadnienia i stworzenia narzędzi do wsparcia emocjonalnego i instrumentalnego personelu stykającego się z problemem.
Ocena jakości życia pacjentów poddawanych hemodializie
Authors: Witkowska Aleksandra 
Published: February 2023

Wstęp. Niniejsza praca stanowi próbę oceny jakości życia pacjentów poddawanych hemodializie. Ta ze względu na dotkliwość oraz uporczywość choroby powoduje poważne obciążenia. W związku z tym jakość życia może być różna w zależności od zastosowanych metod leczenia, wieku, wsparcia najbliższych, ale również długości choroby.
Cel. Celem niniejszej pracy jest ocena jakości życia pacjenta dializowanego.
Materiał i metody. W pracy wykorzystano metodę sondażu diagnostycznego. W tym celu opracowano własny kwestionariusz ankiety oraz kwestionariusz SF 36. Dzięki temu do badania zaproszono 100 osób, które wskazały na własne doświadczenia z chorobą.
Wyniki. W ramach przeprowadzonych badań dowiedziono, że osoby różnie reagują na chorobę. Jest to uzależnione od wieku, ale i też od chorób współistniejących. Poza tym nie można zapomnieć, iż np. praca zawodowa oraz ilość spraw, które trzeba dostosować do warunków życia powoduje, że chorzy różnie oceniają swoje życie. Najczęściej jest to ocena średnia lub dobra.
Wnioski. Na podstawie przeprowadzonych badań dowiedziono, że osobom młodym trudniej pogodzić się z chorobą. To samo odnosi się do stanów emocjonalnych. Jedne osoby wspierane przez najbliższych lepiej poradzą sobie z chorobą, a inne gorzej. Może to być uzależnione od obowiązków, ale również od ich planów na życie. Dodatkowo wiele osób chorych to osoby w podeszłym wieku, a zatem zmagają one z licznymi chorobami towarzyszącymi. Mimo jednak wielu nowoczesnych metod leczenia życie pacjentów jest do pewnego stopnia ograniczone.

Mortality Risk of Patients Treated in Dialysis Facilities with Payment Reductions under ESRD Quality Incentive Program
Authors: Griffin Shannon M. , Marr Jeffrey , Kapke Alissa , Jin Yan , Pearson Jeffrey , Esposito Dominick , Young Eric W. 
Published: February 2023

Background
The Centers for Medicare & Medicaid Services End-Stage Renal Disease Quality Incentive Program (ESRD QIP) measures quality of care delivered by dialysis facilities and imposes Medicare payment reductions for quality lapses. We assessed the association between payment reductions and patient mortality, a quality indicator not included in the ESRD QIP measure set.

Methods
Association between mortality and ESRD QIP facility payment reduction based on the year of performance was expressed as the unadjusted rate and patient case-mix–adjusted hazard ratio. We also measured association between mortality and 1-year changes in payment reductions. Retrospective patient cohorts were defined by their treating dialysis facility on the first day of each year (2010–2018).

Results
Facility performance resulted in payment reductions for 5%–42% of dialysis facilities over the 9 study years. Patients experienced progressively higher mortality at each payment reduction level. Across all years, unadjusted mortality was 17.3, 18.1, 18.9, 20.3, and 23.9 deaths per 100 patient-years for patients in facilities that received 0%, 0.5%, 1%, 1.5%, and 2% payment reductions, respectively. The adjusted hazard ratio showed a similar stepwise pattern by the level of payment reduction: 1.0 (reference), 1.08 (95% confidence interval [CI], 1.07 to 1.09), 1.15 (95% CI, 1.13 to 1.16), 1.19 (95% CI, 1.16 to 1.21), and 1.34 (95% CI, 1.29 to 1.39). Strength of the association increased from 2010 to 2016. Patients treated in facilities that improved over 1 year generally experienced lower mortality; patients in facilities that performed worse on ESRD QIP measures generally experienced higher mortality.

Conclusions
Patient mortality was associated with ESRD QIP facility payment reductions in dose-response and temporal patterns.
Nanostructured lubricant additives for titanium alloy: Lubrication by the solid-liquid interface with Coulomb repulsion
Authors: Duan Linlin , Jia Dan , Li Jian , Liu Jianfang , Duan Haitao 
Published: February 2023

In this work, the advantage of Coulomb repulsion in the intermolecular
forces experienced by molecules on the solid-liquid nanosized contact
interface is taken, and the superior friction-reducing property of
Cu3(PO4)2·3H2O (CuP) oil-based additives has been confirmed for titanium
alloy. 3D CuP nanoflowers (CuP-Fs) with a strong capillary absorption
effect are prepared to achieve the homogeneous mixing of solid CuP and
lubricating oil. Lubrication by CuP-Fs additives for titanium alloy,
friction coefficient (COF) can be reduced by 73.68%, and wear rate (WR)
reduced by 99.69%. It is demonstrated that the extraordinary
friction-reducing property is due to the repulsive solid-liquid
interface with low viscous shear force originating from Coulomb
repulsion between polar water molecules in CuP and non-polar oil
molecules. However, any steric hindrance or connection between this
repulsive solid-liquid interface will trigger the adhesion and increase
the viscous shear force, for example, dispersant, hydrogen bondings, and
shaky adsorbed water molecules. Besides, the lamellar thickness of CuP
and molecular size of lubricant both have a great influence on
tribological properties. Here the lubrication mechanism based on
interface Coulomb repulsion is proposed that may help broaden the scope
of the exploration in low-friction nanomaterial design and new lubricant
systems.
ARAH KIBLAT DAN WAKTU SHALAT Studi Validitas Koordinat Geografis Kecamatan Dalam Wilayah Kabupaten Lampung Tengah
Authors: Rohmat Rohmat , Nurhayati Agustina 
Published: February 2023

Salah satu bentuk ibadah mahdlah adalah shalat lima waktu. Shalat memiliki tata cara dan persyaratan yang harus dipenuhi, di antara syarat sah shalat adalah menghadap kiblat (Ka’bah) dan masuk waktu shalat. Waktu shalat dipengaruhi oleh posisi matahari pada suatu tempat, sehingga antara tempat yang satu dan yang lainnya di muka bumi ini berbeda waktunya. Begitu pula dengan arah kiblat juga di pengatruhi oleh posisi suatu tempat di muka bumi ini dari Ka’bah. Lampung Tengah sebagai sebuah kabupaten memiliki wilayah yang sangat luas yang meliputi dua puluh delapan kecamatan, dan untuk mendapatkan jadwal waktu shalat dan arah kiblat yang benar, maka harus diketahui koordinat geografis kecamat-kecamatan di Kabupaten Lampung Tengah, dari koordinat geografis maka arah kiblat kecamat-kecamatan di Kabupaten Lampung Tengah memiliki azimut yang berbeda sesuai dengan koordinat geografis kecamatan masing-masing, dan awal waktu shalatnya terdapat selisih waktu satu menit bahkan sama di antara kecamatan-kecamatan tersebut. Karena hal tersebut maka dalam penyusunan jadwal waktu shalat kecamatan-kecamatan di Kabupaten Lampung Tengah cukup dibuat satu jadwal waktu shalat saja yaitu dengan data koordinat geografis Kecamatan Lampung TengahKata Kunci: arah kiblat, awal waktu shalat, dan koordinat geografis
