Authors: Choi Byung Sun , Kim Jung Min , Han Hyuk-Soo 
Published: October 2022

Abstract
Background
There has been no study examining lateral tibiofemoral (TF) osteoarthritis (OA) and objective decision-making factors affecting when patients decide to have total knee arthroplasty (TKA). The purpose of this study was to assess which factors and their thresholds cause patients with lateral TF OA to decide on TKA.

Methods
We conducted a retrospective cohort study and identified patients who had initially been diagnosed with isolated lateral TF OA from October 2004 to February 2021. We finally included 56 patients; patients who had chosen conservative treatment followed by in-depth interviews for the deliberation stage (n = 32), and the other patients who decided to undergo TKA for the decision-making stage (n = 24). Demographic, clinical, and radiographic characteristics were considered candidate predictive factors. Radiographic variables included the Ahlbäck grade, hip–knee–ankle (HKA) angle, joint line convergence angle (JLCA), and TF subluxation. Univariate and multivariate logistic regression analyses were performed.

Results
Clinically, the pain visual analog scale (VAS) score was significantly higher and the knee flexion angle was lower at the decision-making stage. Radiographic measurements showed that the Ahlbäck grade, HKA angle, JLCA, and TF subluxation measured at the center, in addition to the tibiotalar angle, differed statistically between the two stages. According to univariate analyses, two clinical characteristics and six radiographic variables on the ipsilateral side of the leg, and one radiographic variable on the contralateral side of the leg were included as factors influencing the patients’ decision to undergo TKA. After making adjustments based on multivariate analysis, the ipsilateral knee pain VAS (OR = 1.61; 95% CI = 1.14–2.28, p = 0.007) and medial TF subluxation measured at the center (OR = 1.14, 95% CI = 1.01–1.32, p = 0.072) were found to be significant factors for choosing TKA. The area under the curve (AUC) for pain VAS was 0.757 and the cutoff value was 4.5. The AUC for TF subluxation measured at the center was 0.697 and the cutoff value was −4.10% of medial TF subluxation.

Conclusion
Higher ipsilateral knee pain VAS and more severe medial TF subluxation measured at the center were independent factors affecting patient decisions to undergo TKA with lateral TF OA. Understanding the determining factors that may affect patient decision-making when considering TKA may be an essential aspect of evaluating the prognosis of patients with lateral TF OA.

Published: October 2022

Abstract
Background
Mucoid degeneration of the anterior cruciate ligament (ACL) has been shown to cause restricted terminal range of motion and rest pain. If present in a patient undergoing unicompartmental knee arthroplasty, it can deteriorate the final outcome. This study aims to compare functional and clinical outcomes of debulking the mucoid ACL in patients undergoing mobile-bearing unicompartmental knee arthroplasty (UKA).

Methods
Patients with mucoid ACL undergoing mobile-bearing UKA at five different centres by five different arthroplasty surgeons were included. They were segregated into two groups matched for all demographic and pre-operative values: group A did not undergo debulking; group B underwent open debulking by a 15-number blade prior to UKA. Patient-related outcome measures, rest pain, clinical outcomes, and subjective patient satisfaction were recorded and compared at 2 years follow-up.

Results
A total of 442 patients (226 patients underwent debulking, 216 patients did not undergo debulking) were included. Both groups showed overall improvement after surgery, however, patients who underwent debulking performed better at 2 years follow-up in terms of Knee Society functional score, International Knee Documentation Committee scores, range of motion, rest pain and overall patient satisfaction (p < 0.05) as compared with their counterparts.

Conclusions
Debulking of mucoid ACL in patients undergoing unicompartmental knee arthroplasty significantly reduces the rest pain and improves the final range of motion of the knee joint, subsequently improving the overall functional and clinical outcome of the patient and resulting in greater patient satisfaction.

Abstract
Purpose
This study aimed to investigate the effect of medial open wedge high tibial osteotomy (MOWHTO) on patellofemoral joint osteoarthritis (PF OA) progression and its outcome according to the degree of preexisting PF OA.

Materials and methods
Patients who underwent biplane MOWHTO between January 2006 and December 2018 were retrospectively reviewed. The patients were divided into two groups according to the degree of PF OA: non-PF OA [Kellgren–Lawrence (K–L) grade 0–1] and PF OA (K–L grade 2–3). Propensity score matching was performed between the two groups, and comparative analysis was performed on clinical scores and radiographic parameters and grade.

Results
After propensity score matching, 83 patients were selected for each group. At postoperative follow-up, clinical scores were improved significantly compared with preoperative scores in both groups; however, there were no significant differences between the groups. There were also no significant differences between the two groups in radiographic parameters. The radiographic grade of PF OA indicated a slight progression in osteoarthritis in both groups; however, PF OA tended to progress further in the PF OA group.

Conclusions
MOWHTO did not result in significant differences in outcomes at postoperative follow-up; however, preexisting PF OA contributed to PF OA progression after MOWHTO.
Noninvasive assessment and risk factors of liver fibrosis in pediatric patients with beta thalassemia major using transient elastography
Authors: Mohamed Yasmen Awadalh , Morgan Dalia Saber , Hussein Asmaa Mohamed , Mohamed Alaa Aboud 
Published: October 2022

Abstract
Background
In beta-thalassemia major (TM) patients, levels of liver iron overload and the presence of chronic hepatitis C are directly correlated with the onset and severity of liver fibrosis. A noninvasive approach that can evaluate cirrhosis and liver fibrosis in these patients is transient elastography (TE). We aimed to find out the role of noninvasive elastography in the assessment of liver fibrosis in young beta-thalassemia major patients receiving frequent blood transfusions. Identifying the patients' risk factors for liver fibrosis is another goal. The study comprised 53 patients, all of whom had a thorough history-taking procedure, clinical examination, and investigations such as CBC, serum ferritin, HCV and HBV serology, and liver function testing. It was carried out transient elastography to find liver fibrosis.

Results
According to transient elastography, 52.8% of the patients had severe fibrosis (F2 and higher). 9.4% of people had positive HCV serology results. Significant liver fibrosis was correlated with all serum ferritin levels (708.2 ± 182.1, 3213.5 ± 1272.9, nonsignificant vs. significant fibrosis), HCV infection, age, blood transfusion frequency, and irregular chelation therapy. But no significant correlation regarding sex and BMI was detected.

Conclusion
Transient elastography is an alternate noninvasive approach that assesses liver fibrosis in beta-thalassemia major patients. The risk of liver fibrosis is related to iron overload, HCV seropositivity, advanced age, frequent blood transfusion, and irregular chelation therapy.
Polya urn model-based performance assessment of PSC bridges: prestress loss consideration
Authors: Balaji Rao K. , Anoop M. B. 
Published: October 2022

AbstractA methodology for performance assessment of prestressed concrete (PSC) girder bridge system, based on strain monitoring in limited number of girders, is proposed in this paper. The methodology uses Polya urn model for determining probabilities of the bridge system being in different condition states with respect to loss of prestress. Performability measure is used for describing the performance of the bridge system. A condition state is assigned for the bridge system from a predefined set of condition states. The time for detailed inspection is determined as the time instant at which the performability of the bridge system becomes less than the target/required performance level. Performance assessment of a bridge system with one hundred PSC girders is considered for illustrating the methodology. The obtained values of condition state probabilities and performability for the considered scenarios (i.e., different number of monitored girders with prestress loss exceeding the allowable value) suggest that the methodology is able to consider the value of available information.

AbstractTo optimize the optimal nozzle structure and multiple nozzle arrangement for hydrate jet crushing and to promote the development of solid fluidization extraction technology for shallow unconformity hydrate in China’s oceans, the submerged jet flow field of six commonly used nozzle structures in the downhole in-situ jet crushing process was analyzed on the basis of the solid fluidization extraction process in double-layer pipes, and the effect of the jet hole arrangement on the overflow performance of hydrate slurry in the outer annulus of double-layer pipes was also investigated. It was demonstrated that tapered straight nozzles were preferably selected as the nozzle type for hydrate solid fluidization mining process based on jet core stage length, jet energy dissipation rate, and jet fluid axial velocity. In the meantime, the optimum arrangement of the nozzles was preferred on the basis of the annular pressure drop and the flow resistance coefficient, with the number of single circle not higher than 3 and the axial spacing of the nozzles not lower than 50 mm. This study can provide a theoretical basis for nozzle selection and tool design for the solid fluidization jet crushing process of marine unconformable hydrates.

Published: October 2022

AbstractEfficiency in the industrial sector is a priority when seeking to minimize production costs and reduction in losses. Harmonic generation and associated losses need to be treated carefully with broad implementation of variable speed induction motor applications. The effect of these induced losses can add up to a significant loss. This study uses statistical tools alongside synthesized models to deduce and compare outcomes from regulated and unregulated converters in which harmonics may be triggered by switching algorithm of modern switch-mode power supplies and other inductive loads attached to supply bus system. These harmonics accumulate over time due to losses propagating through connected equipment when changes occur on the bus system. In this regard, results obtained from investigating and comparing three original equipment manufacturer variable speed drives that were exposed to voltage unbalance and complex harmonic conditions are presented in this study. A conclusion accomplished from the investigation and comparison suggests that generation of 6-pulse uncontrolled rectifier losses is negligible. Experimental validation confirms that unregulated 6-pulse converter produces on average more harmonics compared to the regulated converter of standard as recommended in guideline to permissible harmonic tolerance.
Expropriation between a legal figure and an approach for urban development: global trends and Egyptian reflections
Authors: Elbortokaly Amira Abdelrazik , Shalaby Ahmed Mohamed , Gammaz Sherin Ali 
Published: October 2022

AbstractExpropriation of land is considered a crucial instrument of any development practice. The legitimacy of expropriation is essentially reinforced as it is employed for the public interest, often implied as infrastructure and public services. While in the private property on one side and the public interest on the other, urban development acts to be the art of getting the right balance. Despite urban development paradigms significantly affecting expropriation practices, most reviewed literature focused on legal aspects of expropriation. However, few were attentive to addressing the relation between expropriation and the urban universe. What are the current trends of the expropriation function and how extensively is it used for urban development? It can be elaborated as the study’s core question, while the research aims at mapping the development of the expropriation function and how extensively expropriation is used across time and space. Therefore, the study adopts a qualitative comparative approach to explore the global trends of expropriation for urban development and map convergence and deviations. The proposed criteria for comparison aim to discover how extensively expropriation is used, the legal changes and the institutional contexts. In addition, the applied part of the study uses a case study analysis method. A chronological timeline analysis of the Egyptian case was conducted to explore the nature of expropriation practices of Nasser’s time (1956–1970) to Mubarak’s time (1981–2011) in Egypt.Globally, expropriation practices have a heterogeneous nature. Certain features, however, are common enough to justify classifying practices for this study. The research comes up with a schematic mapping intending not to be comprehensive but flexible enough to be applied as a framework to analyse and compare other cases in different contexts. Finally, the research concludes by comparing and positioning the Egyptian case in the light of the global trends and provides principal lessons to planners, governmental parties, and policy-makers.

Cel pracyLegalne materiały pornograficzne stanowią niejednolitą grupę materiałów audiowizualnych, które przedstawiają jedną lub większą liczbę osób powyżej osiemnastego roku życia podczas podejmowania czynności o charakterze seksualnym. Celem badań było wytrenowanie modelu sieci neuronowej do klasyfikacji zadanych typów materiałów pornograficznychMetodaMateriały włączone do zbioru treningowego (3600 materiałów) i walidacyjnego (900 materiałów) podlegały restrykcyjnym kryteriom włączenia, a następnie były ręcznie klasyfikowane. Na tak przygotowanych materiałach wytrenowano głęboką sieć neuronową. Do badań zaklasyfikowano sześć modeli bazujących na różnych architekturach konwolucyjnych sieci neuronowych (ResNet152, ResNet101, VGG19, VGG16, Squeezenet 1.1, Squeezenet 1.0). Każdy z nich został wytrenowany na tej samej grupie zdjęć, a proces treningu odbywał się przy wykorzystaniu biblioteki fast.ai.WynikiStworzono model, który w porównaniu do modelu pilotażowego, umożliwia klasyfikację większej ilości typów materiałów pornograficznych, przy jednocześnie większej skuteczności, a dzięki opisaniu każdego zdjęcia, znane są również ograniczenia dokonywanej klasyfikacji.WnioskiOmówiono przyszłe zastosowania modelu w seksuologii klinicznej oraz psychiatrii. Rozwój prac nad głębokimi sieciami neuronowymi w seksuologii wydaje się być szczególnie obiecujący z co najmniej dwóch powodów. Po pierwsze, możliwe jest stworzenie narzędzia przeznaczone do automatycznego wykrywania materiałów pornograficznych z małoletnimi i zastosowanie go w trakcie postępowania sądowego. Po drugie, po dotrenowaniu zaprezentowanego modelu o zdjęcia kobiet oraz mężczyzn, którzy nie podejmują aktywności seksualnej, można by wykorzystać model do filtrowania treści nieodpowiednich do oglądania przez małoletnich

Authors: Motes Arunee 
Published: October 2022

Sedative medications have been used in intensive care units (ICU) to minimize discomfort, prevent pain /anxiety, allow invasive procedures, reduce stress, and improve synchrony in mechanically ventilated (MV) patients. However, these drugs can have adverse effects resulting in increased length of ICU/hospital stay, health care costs, morbidity, and mortality. This review summarizes the mechanisms of action, usual doses, side effects, adverse effects, contraindications, and recent studies of sedatives which are frequently used in adult ICUs and the sedation assessment tools for measuring quality and depth of sedation in adult ICU patients.

Clinical effectiveness of generic vancomycin products compared to Vancocin CP® in patients with methicillin-resistant Staphylococcus aureus infections: A retrospective cohort
Authors: Castaño-Rendón Juliana , Sánchez López Sebastián , Padierna Andrés , Palacio María , Tobon Laura , Ossa María , Muriel Carolina , Tello Johana , Jaimes Fabián 
Published: October 2022

Introduction: Approval of generic drugs requires only bioequivalence studies. Some research suggests that generic vancomycin is not clinically equivalent to the branded drug, and this exposes patients to therapeutic failure and the development of microbial resistance.
Aims: Compare the rates of microbiological and clinical failure between generic vancomycin and Vancocin-CP®.
Methods: Retrospective cohort analysis of hospitalized adults with culture-proven methicillin-resistant Staphylococcus aureus infection, treated with vancomycin in a tertiary care hospital in Medellín, Colombia. General clinical variables, laboratory findings, severity and mortality scores, and type of vancomycin used were recorded. Logistical regression models, adjusted for potential confounders, were fitted to estimate the effect of vancomycin on clinical and microbiologic outcomes.
Results: Of 209 patients, 153 (73.2%) received generic vancomycin and 56 (26.8%) Vancocin-CP®. Systems more commonly affected were skin and soft tissues (28.5%), blood with involvement of catheters (27.6%) and blood without the involvement of catheters (23.3%). There were 62 clinical failures (29.5%) and 41(38%) microbiological failures. The hospital mortality rate was 15% (n = 31); only 7 (3.4%) episodes of adverse drug reactions were documented. No difference was found in the risk of clinical or microbiological failure between Vancocin-CP® and generic products with OR = 2.3 (95% CI = 0.8; 6.3) and 0.89 (95% CI = 0.4; 1.9), respectively.
Conclusion: There were no association between the use of generic vancomycin and the outcomes of clinical or microbiological failure. Sample size is an important limitation for these findings.

Published: October 2022

Collagenous gastritis is a rare cause of heartburn in adults. Histopathological examination of gastric mucosal biopsy from the stomach shows submucosal collagen deposition. The pathophysiologic mechanism is unknown, and collagenous gastritis cases have been associated with certain drugs, such as olmesartan and non-steroidal anti-inflammatory drugs, and certain medical conditions, such as common variable immunodeficiency, primary IgM deficiency, autoimmune disorders, and psoriatic arthropathy. Here we report a case of collagenous gastritis in a 29-year-old woman with psoriatic arthropathy who presented with persistent heartburn. She was successfully treated with oral pantoprazole.

Key words: heartburn, collagenous gastritis,
