Published: November 2020

AimsTo compare time dependent functional improvement for patients with medial, respectively lateral knee osteoarthritis (OA) after treatment with opening wedge osteotomy relieving the pressure on the osteoarthritic part of the knee.MethodsIn all, 49 patients (52 knees) with a mean age of 47 years (31 to 64) underwent high tibial osteotomies (HTO), and 24 patients with a mean age of 48 years (31 to 62) low femoral osteotomies (LFO) with opening wedge technique due to medial, respectively lateral knee OA with malalignment. All osteotomies were stabilized with a Puddu plate and bone grafting performed in the same time period (2000 to 2008). The patients were evaluated by the Knee Injury and Osteoarthritis Outcome Score (KOOS) pre-operatively and at six months, and at one, two, five, and ten years postoperatively. The knee OA was graded according to the Ahlbäck and Kellgren-Lawrence radiological scoring systems.ResultsThe mean angular corrections were 8.0° (4° to 12°) for the HTO and 9.6° (4° to 20°) for the LFO. Both the pre-operative KOOS and the osteoarthritic gradings were similar for the two patient groups. The five subscores of KOOS increased significantly during the postoperative period (p < 0.001 to 0.029) levelling out after one year in both groups. The KOOS subscore symptoms was significantly higher for patients with HTO than those with LFO at all follow-up times, for sport and recreation in the period one to five years, and for pain and quality of life at two to five years (p < 0.001 to 0.009). Eight HTOs (15%) and five LFOs (21%) were converted to total knee arthroplasty after mean 6.7 years (2.0 to 9.8) and 5.4 years (4.0 to 8.0) respectively. The ten-year osteotomy survival rates were 88% for the HTO and 79% for the LFO (p = 0.745).ConclusionPatients with unicompartmental knee OA improved after a corrective opening wedge osteotomy, but four of the five subscores of KOOS were significantly higher for those with medial than those with lateral OA in most of the ten-year follow-up period.

Long-distance distributed acoustic sensing utilizing negative frequency band
Authors: Xiong Ji , Wang Zinan , Wu Yue , Wu Han , Rao Yunjiang 
Published: November 2020

Wider bandwidth always means better overall performance for an information system. Naturally, this criterion can also be applied to phase-sensitive optical time domain reflectometry (Φ-OTDR), which is a typical distributed optical fiber sensing (DOFS) system. Thus, an indispensable way to enhance the performance of Φ-OTDR is to increase the available system bandwidth, which is usually limited by the electrical components. As a kind of frequency resources, the negative frequency band (NFB) has been used in communication systems based on coherent receivers and high-order modulation, but is still rarely used in DOFS. In this paper, we make a comprehensive study on how to utilize NFB in Φ-OTDR and thus double the available system bandwidth. Moreover, the related improvement of sensing performance is experimentally demonstrated. The positive and negative frequency multiplexing is utilized together with frequency division multiplexing to break the inherent trade-off between sensing distance and scan-rate. As a result, 21.6 kHz scan-rate is experimentally achieved on a 103 km fiber, with

strain resolution and 9.3 m spatial resolution. To the best of our knowledge, this is the best sensing performance in long distance Φ-OTDR > 100 km. The proposed scheme can also be applied to other DOFS systems with heterodyne-detection, opening up new possibilities for performance enhancement in DOFS systems.

Published: November 2020

Diffractive optical surfaces have attractive properties for use in optical systems, like reducing weight and correcting for chromatic aberrations, but fabrication of high-quality glass diffractive optics is challenging, preventing it from being widely adopted in commercial applications. In this Letter, we report on a fabrication method to address molding challenges for high-surface-quality diffractive glass optics at molding temperatures up to 550°C, including selection of mold material, mold fabrication, precision glass molding, durability, and stability of the mold. To enable optimal mold machining and easy mold release, nickel phosphorous (NiP) is chosen as the plating material for its cutting performance and anti-adhesion properties, and copper-nickel C71500 (CuNi) is selected as the mold substrate because its coefficient of thermal expansion (CTE) is close to NiP. By the proposed method, diffractive glass optics with 2 nm Sa surface roughness is demonstrated.

Published: November 2020

A multifunctional optical fiber sensor fabricated by asymmetric offset splicing is proposed in this Letter. The light is divided into several parts at the offset interface, among which the transmitted light forms the Mach–Zehnder interference (MZI) spectrum while the reflected light forms the Fabry–Perot interference (FPI) spectrum. The online monitoring system is built to create a better light distribution at the offset interface. Theoretical analysis and experimental verification are carried out. The results of the experiment show that the proposed sensor has good characteristics of salinity and temperature, and the salinity sensitivity is as high as

‰ in the range of 20–40‰; the temperature sensitivity is better than 2.17 nm/°C in the range of 28–48 °C. The two interferometers involved have different responses to temperature and salinity, contributing to the effective elimination of cross-sensitivity. The proposed optical fiber sensor has the benefits of compact size, high sensitivity, and multispectral measurement function.

Laser-based light detection and ranging (lidar) plays a significant role in both scientific and industrial areas. However, it is difficult for existing lidars to achieve high speed, high precision, and long distance simultaneously. Here, we demonstrate a high-performance lidar based on a chip-scaled soliton microcomb (SMC) that can realize all three specialties simultaneously. Aided by the excellent properties of ultrahigh repetition rate and the smooth envelope of the SMC, traditional optical frequency comb (OFC)-based dispersive interferometry is heavily improved and the measuring dead zone induced by the mismatch between the repetition rate of the OFC and resolution of the optical spectrum analyzer is totally eliminated. Combined with an auxiliary dual-frequency phase-modulated laser range finder, the none-dead-zone measurable range ambiguity is extended up to 1500 m. The proposed SMC lidar is experimentally implemented in both indoor and outdoor environment. In the outdoor baseline field, real-time, high-speed (up to 35 kHz) measurement of a long distance of

is achieved with a minimum Allan deviation of 5.6 μm at an average time of 0.2 ms (27 nm at an average time of 1.8 s after high-pass filtering). The present SMC lidar approaches a compact, fast, high-precision, and none-dead zone long-distance ranging system, aimed at emerging applications of frontier basic scientific research and advances in industrial manufacturing.

Published: November 2020

Napjaink gyorsan változó információs társadalmában a tanároknak folyamatosan felül kell vizsgálniuk és kihívások elé kell állítaniuk nézeteiket, módszereiket, mivel a sokszínű osztályközösségek, illetve a változó tanulási formák, források és tanulási környezetek gyors, adaptív pedagógiai reakciókat igényelnek (Lampert, 2010). A reflektív gondolkodás elengedhetetlen kelléke a tanárok szakmai repertoárjának így a 20. század végétől a reflektivitás egyre nagyobb hangsúlyt kap a pedagógusképzésben (Kinsella, 2007; Collin, Karsenti és Komis, 2013).
A tanárszakos hallgatók reflektív gondolkodásának támogatására, illetve feltárására számos módszer áll rendelkezésre mind hazai, mind nemzetközi viszonylatban. Ezeknek a tanulmányoknak szisztematikus feldolgozását célul kitűző kutatások azonban kis számban vannak csak jelen a hazai szakirodalomban.
Jelen tanulmány, a reflektív naplónak, mint a reflektivitás egyik hatékony eszközének tanárképzésben való alkalmazási lehetőségeit tárja fel a szakirodalmi elemzés módszerével. A kutatásba bevont tanulmányok céljait és eredményeit vizsgálja a reflektív naplóírás tanárszakos hallgatók fejlődésére gyakorolt hatásainak relevanciájában. A reflektív naplókkal kapcsolatos kutatások eredményei rávilágítottak, hogy a naplóírás különböző területen gyakorolhat hatást a tanárrá válás folyamatában. Támogathatja a szakmai tudás elmélyülését, tudatosabbá teheti a tanári gyakorlatot, de segítheti a tanítással kapcsolatos attitűdök, nézetek felülvizsgálatát is. Emellett fejlesztheti a tanárszakos hallgatók reflektivitásának szintjét és hozzájárulhat inkluzív szemléletmódjuk kialakításához.

Published: November 2020

INTRODUCTION:
Per-oral endoscopic myotomy (POEM) is an effective modality for the management of achalasia. Tension pneumoperitoneum is a significant complication that causes hemodynamic instability, generally within the periprocedural period.

METHODS:
Here, we report 2 cases of delayed tension pneumoperitoneum that was recognized and treated several hours after uncomplicated POEM.

RESULTS:
These cases illustrate the importance of continued vigilance for this complication outside of the immediate periprocedural period as well as the utility of computed tomography-guided aspiration in managing it.

DISCUSSION:
When discharging patients after POEM, caregivers should be aware of this rare complication and alert patients to return for immediate care when it happens.

Teoretická štúdia vychádza z toho, že súčasnou výzvou pre subjekty v ekonomike sa stala udržateľnosť. Medzi kroky vedúce k transformácii ekonomickej teórie a následne k transformácii ekonomiky na udržateľnú, patrí vývoj nových trendov v ekonomickom myslení a rovnako aj nových iniciatív v ekonomike v znamení udržateľnosti. Na ich vzniku a rozvoji sa podieľajú ekogramotné subjekty. V štúdii je poodhalený teoretický rámec pre ekogramotnosť a zdôraznený jej význam pre udržateľnosť a rozvoj nových trendov ekonomického myslenia i ekonomických iniciatív v znamení udržateľnosti. Ekogramotnosť je prezentovaná ako nová vízia reality, ale aj ako atribút alebo kompetencia, ktorá je založená na porozumení skutočnej hodnoty prírodných entít a životného prostredia. Predpokladá vedomé úsilie subjektov v ekonomike minimalizovať negatívne účinky, ktoré sprevádzajú rozvoj ekonomiky, na prírodu a životné prostredie. Vzhľadom na prípravu budúcich odborníkov pre oblasť ekonomiky je zdôraznená ekogramotnosť ako dôležitý nástroj vzdelávania pre udržateľný rozvoj. Aj rozvoj nových trendov ekonomického myslenia a iniciatív v znamení udržateľnosti sa realizuje vďaka ekogramotným subjektom, a tak vzdelávanie zamerané na ekogramotnosť je vyzdvihnuté najmä v tých vzdelávacích inštitúciách, ktoré pripravujú odborníkov pre ekonomickú sféru.
Applying floodplain geomorphology to flood management (The Lower Vistula River upstream from Plock, Poland)
Authors: Wierzbicki Grzegorz , Ostrowski Piotr , Falkowski Tomasz 
Published: November 2020

Abstract
Using remote sensing extended on geological and topographical maps and verified by the field work, we present the flood management and study the geomorphic features of the floodplain of a large, sand bed, untrained but embanked river in order to determine the flood hazard and to predict future flood scenarios. In geomorphological mapping, we focus on the landforms: crevasse channels and splays, flood basin, chute channels, side arms, floodplain channels, dunes and fields of aeolian sand. We base the flood risk assessment on consultations with environmental engineers who design new technical structures that control inundation (cut-off walls and lattice levees). We describe a levee breach as a result of piping (inner erosion) in a high hydraulic gradient condition and its effect (scour hole) as an erosional landform consistent with the repetitive pattern of erosion and deposition formed by an overbank flow on a floodplain. We reveal an existence of homogenous morphodynamic reaches in the river valley.

Published: November 2020

This study analyses the extraction process parameters of huracrepitan seed oil using the Adaptive Neuro-Fuzzy Inference System (ANFIS) and Artificial Neural Network (ANN). The experiments were conducted at temperature (60–80 °C), time (4–6 h), and solute/solvent ratio (0.05–0.10) with output parameter as oil yield. Sensitivity analysis shows that temperature and time had the most significant effect on the oil yield. The oil yield estimation performance indicators are: ANN (&lt;i&gt;R&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt; = 0.999, MSE = 5.63192E-13), ANFIS (&lt;i&gt;R&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt; = 0.36927, MSE = 0.42331). The results show that ANN gave a better prediction than ANFIS.

Published: November 2020

Background
The treatment of acromegaly resistant to first-generation somatostatin receptor ligands (SRLs) is often difficult. Pegvisomant and Pasireotide LAR are mostly used in these subset of patients, as second line therapies. Choice of the type of second line therapies is difficult, since predictors of response are still unclear, impairing personalized therapy. We aimed to investigate predictors of response to Pegvisomant and Pasireotide LAR.

Methods
Seventy-four acromegaly patients entered this observational, cross-sectional and retrospective study if (i) resistant to high dose first-generation SRLs and (ii) treated with Pegvisomant and Pasireotide LAR for at least 12 consecutive months. Patients treated with radiotherapy in the previous 10 years were excluded.

Results
Fourty-one patients were treated with Pegvisomant and 33 with Pasireotide LAR. At the end of the study, acromegaly was controlled in 35 patients treated with Pegvisomant (85.4%) and in 23 treated with Pasireotide LAR (69.7%). In this cohort, a poor Pegvisomant response and a shorter progression free time were observed in cases with tumor extension to the third ventricle (P = 0.004, HR: 1.6, 95%CI: 1.2–4.6), with a Ki67-Li >4% (P = 0.004, HR: 3.49, 95%CI: 1.4–4.0) and with pre-treatment IGF-I >3.3×ULN (P=0.03, HR: 1.3, 95%CI: 1.1–6.0). A poor Pasireotide LAR response and a shorter progression free time were observed in cases with tumor extension to the third ventricle (P=0.025, HR: 1.6 95%CI: 1.4–3.4), pre-treatment IGF-I >2.3×ULN (P=0.049, HR: 2.4, 95%CI: 1.4–8.0), absent/low SST5 membranous expression (P=0.023 HR: 4.56 95%CI: 1.3–6.4) and in patients carried the d3-delated GHR isoform (P=0.005, HR: 11.37, 95%CI: 1.3–20.0).

Conclusion
Molecular and clinical biomarkers can be useful in predicting the responsiveness to Pegvisomant and Pasireotide LAR.

Published: November 2020

OBJECTIVES:Evaluate provider experiences with a bedside tablet inpatient portal application given to hospitalized patients and families across a children’s hospital.METHODS:In this cross-sectional study, English-speaking parents of children &lt;12 years old and adolescents ≥12 years admitted between February and June 2017 to a 111-bed tertiary children’s hospital were given an inpatient portal application (MyChart Bedside; Epic Systems Corporation, Verona, WI) on a tablet (iPad) to use during their stay. The portal included real-time vital signs, test results, medication and problem lists, a daily schedule, educational materials, and provider names and photographs. Portal use was described from electronic health record data, and provider (physician, nurse, and pharmacist) experiences were assessed from surveys.RESULTS:Of 1892 admissions given a tablet over 5 months, 1502 (79.4%) logged in to view their inpatient health record at least once during their hospital stay. No tablets were lost or stolen. Of 101 providers, 96 completed the survey (a response rate of 95%). They reported that patients and/or parents asked them questions about information they found, including laboratory results (45% of respondents), medications (13%), diagnoses (13%), and errors and/or mistakes in care (3%). Few perceived spending more time answering questions related to portal use (8%) or that it increased their workload (11%). In all, 92% of providers wanted patients and parents to continue to be able to use the portal.CONCLUSIONS:Almost 80% of hospitalized patients and parents given a tablet accessed real-time information from the inpatient health record. The portal facilitated communication about test results, diagnoses, and medications and providers overwhelmingly supported its ongoing use.
Shared Decision-making With Parents of Hospitalized Children: A Qualitative Analysis of Parents’ and Providers’ Perspectives

Published: November 2020

OBJECTIVES:Shared decision-making (SDM) is the pinnacle of patient-centered care and has been shown to improve health outcomes, especially for children with chronic medical conditions. However, parents perceive suboptimal involvement during hospitalization. The objective was to explore the perspectives of parents of hospitalized children and their hospital providers on facilitators and barriers to SDM in the hospital and identify strategies to increase SDM.METHODS:A qualitative study was conducted by using semistructured interviews with parents of hospitalized children with and without complex chronic conditions and their pediatric hospital medicine faculty. Parents and faculty were matched and individually interviewed on the same day. Two investigators iteratively coded transcripts and identified themes using modified grounded theory, with an additional author reviewing themes.RESULTS:Twenty-seven parents and 16 faculty participated in the interviews. Four themes emerged: (1) parents and providers value different components of SDM; (2) providers assume SDM is easier with parents of children with medical complexity; (3) factors related to providers, parents, patients, and family-centered rounds were identified as barriers to SDM; and (4) parents and providers identified strategies to facilitate SDM in the hospital.CONCLUSIONS:There is a discrepancy between parents’ and providers’ understanding of SDM, with parents most valuing their providers’ ability to actively listen and explain the medical issue and options with them. There are many barriers that exist that make it difficult for both parties to participate. Several strategies related to family-centered rounds have been identified that can be implemented into clinical practice to mitigate these barriers.

Published: November 2020

OBJECTIVES:Given the high needs and costs associated with the care of children with medical complexity (CMC), innovative models of care are needed. Home-visiting care models are effective in subpopulations of pediatrics and medically complex adults, but there is no literature on this model for CMC. We describe the development and outcomes of a multidisciplinary program that provides comprehensive home-based primary care for CMC.METHODS:Medical records from our institution were reviewed for patients enrolled in our program from July 2013 through March 2019. Demographics, clinical characteristics, and health care use were collected. We compared the differences in pre- and postprogram enrollment health care use using Wilcoxon signed rank test. We applied Cox proportional hazard models to examine the association between the time-dependent postenrollment health care use and numbers of home visits. We collected total claims data for a subset of our patients to examine total costs of care.RESULTS:We reviewed data collected from 121 patients. With our findings, we demonstrate that enrollment in our program is associated with reductions in average length of stay. More home visits were associated with decreased emergency department visits and hospitalizations. We also observed in patients with available cost data that total costs of care decreased after enrollment into the program.CONCLUSIONS:Our model has the potential to improve health outcomes and be financially sustainable by providing home-based primary care to CMC.
