An adaptive probability map for the Discrete Algebraic Reconstruction Technique
Authors:   University of Antwerpen, Frenkel Daniel ,   University of Antwerpen, De Beenhouwer Jan ,   University of Antwerpen, Sijbers Jan
Published: April 2023

The Discrete Algebraic Reconstruction Technique (DART) [1] is a well-known method to reconstruct images from a set of X-ray projections acquired from objects that consist of only a small number of materials. For such materials, DART has been shown to lead to high quality images, even when the number of available projections is small or when the projections are acquired in a limited angular range. The core idea of DART is to reduce the size of the reconstruction problem by iteratively updating only those pixels that are likely to be misclassified. However, DART as proposed in [1] updates the image pixels independent of the material. This paper presents an improved pixel update strategy by introducing a probability map that measures the classification accuracy of each pixel based on its grey value evolution throughout the iterations. Through simulation experiments, we show that, compared to DART, our proposed method either improves upon convergence speed or on quality of the reconstructed image.

A metrological investigation was carried out to determine the effect of plane fitting strategies, filtering and various measurand configurations, on the accuracy of an XCT scanner. Reference measurements were taken on a tactile CMM with expanded uncertainty (k=2) of U=1.5 mm. A series of measurements was performed on a 42 mm aluminium step gauge manufactured by fine milling with a roughness of Ra = 0.2 ?m. The same measurement strategies were used for both XCT and CMM, including application of various filtering and outlier removal techniques with subsequent plane creation on different measurand configurations. The influence of different plane creation techniques on the accuracy was established as a major effect. Gaussian fit plane creation strategy resulted in the best agreement between the measurement results of the two instruments, differences being below 2 ?m for unidirectional and below 8 ?m for bidirectional internal and external measurands. The effect of different filtering and outlier removal techniques on the measurement results was less pronounced on Gaussian fit plane creations, but for outer tangential plane fitting the highest bias detected was 35 ?m for bidirectional internal measurements. Configuration of the measurand also had a major effect on the bias of XCT with respect to CMM measurements.

Introduction: There are many reasons for the failure of a total knee endoprosthesis. The most common are infection, loosening, instability, pain and abrasion of the polyethylene. It is therefore necessary to further develop the current models. This study examines a new completely metal-free ceramic total knee endoprosthesis. There are several reports on the clinical results and biomechanical testings. Non-destructive analysis by computed tomography (CT) is a new tool for analysis of a ceramic knee endoprosthesis. Methods: In this study, 16 samples of a ceramic total knee arthroplasty were scanned including left and right implants (sizes 3 to 6). Each sample was left in its original packaging during scanning in order to preserve its sterile state. During the scanning procedure, two samples of the same size were scanned jointly in order to minimize scanning time. The testing was exclusively non-destructive, which poses a challenge due to the high density of zirconium (6 g/cubic centimeter). We established a non-destructive test protocol especially for ceramic knee implants in which the scanning parameters were optimized and the sample orientation was determined by CT simulations. Additionally, methods for the reduction of beam hardening artifact were applied. Results: It could be shown that a correct presentation in the micro-computer tomograph is possible despite the high density of the ceramic. In the examined specimens, no internal material defects such as pores or fractures were found. A three-dimensional examination, even of objects with a high density, can be carried out flawlessly using the micro-CT. Summary: It was shown that no pores or cracks were found in the tested implants. Non-destructive testing in micro CT is a challenging method. The highly compressed material and the complex geometry of the femoral and tibial implants make measurement difficult. Sophisticated corrective tours of the scanning artifacts and a robust scanning protocol are necessary to achieve optimal results. This study provides the prerequisites for further analysis.

Published: April 2023

Objective: The coronavirus disease 2019 (Covid-19) has significantly affected human health around the world, causing many complications. However, it is not fully understood how the body compositions of individuals affected in the short or long term after disease. In this study, we aimed to show the effects of Covid-19 on body composition and phase angle values, using Bioelectrical Impedance Analayser.
Methods: Subjects were selected from individuals in the 18-60 age group, who had survived COVID-19 disease. 33 individuals who had survived it 1-3 months ago, and 30 individuals who had survived it 3-6 months ago were included in the study.
Results: Effects of COVID-19 on basal metabolism and body composition and the ratio of damaged cells in the body after the disease were determined. Basal metabolic rate, lean body mass, body cell mass, total body fluid, intracellular fluid, and phase angle values were found to be significantly changed in the 3-6 months range compared to that of 1-3 months.
Conclusion: These results indicate that the basal metabolism and body composition parameters of the body become better, and the proportion of damaged cells decreases as time goes on after suffering COVID-19, reaching values close to normal in 1-3 months and quite better values in 3-6 months. It can be concluded that, although covid-19 influences body composition parameters and cell integrity in survivors of Covid 19 disease, these effects are limited to 3-6 months.

Published: April 2023

Introduction: Multiple sclerosis (MS) is an autoimmune disease that causes scar tissue in the nervous system and seriously affects the quality of life of people. Muscle weakness, spasticity and coordination problems are seen primarily in the lower extremities. Strengthening exercises improve muscle strength in people with multiple sclerosis, but there is no consensus on their effect on walking capacity.
Methods: To determine the relationship between gluteus maximus muscle strength, ataxia, balance and walking capacity in Multiple Sclerosis. An experimental study design was applied. Gluteus maximus muscle strength was measured using a dynamometer. Walking capacity was determined by the 6-minute walk test (6MWT) and dynamic gait index (DGI). Balance was evaluated with the one-leg standing test (SLS). The severity of ataxia was measured with the International Ataxia Rating Scale (ICARS). Fatigue was evaluated with VAS and quality of life of all patients with SF36 short form.
Results: EDSS mean of the study = 3.39 ± 1.4; 2 men and 16 women with mean age = 37.17 ± 9.16 years were included. 6MWT, DGI, ALS, ICARS, VAS were different before and after treatment (p<0.05). There was no significant difference other than physical function and general health among the sub-parameters of SF36 (p>0.05). Correlation of muscle strength with ataxia, gait and balance was not significant (p>0.05)
Conclusion: In individuals with MS, the fact that the treatment program consists of modalities that include balance and sensory exercises as well as muscle strengthening exercises increases the success of rehabilitation.

Authors: Evren Ismail , Sam Emre
Published: April 2023

Introduction: There is no study investigating the factors predicting postoperative febrile urinary tract infection (fUTI) in pediatric patients. We aimed to determine the factors predicting postoperative fUTI in pediatric patients who underwent ureterorenoscopic lithotripsy (URS-L).
Methods: Pediatric patients who underwent URS-L due to ureter or kidney stones in our clinic between 2012 and 2019 were analyzed retrospectively. The demographic data, stone characteristics, intraoperative and postoperative data of those with and without postoperative fUTI were compared. Univariable and multivariable binary logistic regression analysis was performed to determine predictors of fUTI.
Results: A total of 136 patients were included in the study. Postoperative fUTI developed in 17 patients (12.5%). History of stone surgery, history of UTI, presence of nephrostomy/D-J stent, type of surgery, operation time, length of stay, and presence of complication except fUTI were found to be significantly different in the fUTI group. In the univariate analysis, history of stone surgery, history of UTI, presence of nephrostomy/D-J stent, type of surgery, operation time, and presence of complication except fUTI were determined as factors predicting fUTI. In multivariate analysis, only the history of UTI was identified as an independent predictive factor.
Conclusion: In pediatric patients, infectious complications constitute the majority of complications after URS-L. History of UTI is the only independent factor that predicts postoperative fUTI after URS-L.

Published: April 2023

Objective: Primary care, which is often the first level of contact for patients with various communicable diseases (CDs) and noncommunicable diseases (NCDs), might exhibit patterns of injectable drug utilization different from hospitals. We aimed to examine injection prescribing to adults with CD or NCD in primary care.
Methods: In this retrospective study, single-diagnosis injectable drug-containing prescription data from Family Medicine Information System comprising 32 provinces of Turkey were analysed. The prescriptions were grouped by diagnosis as “CD” (n=3848) and “NCD” (n=9338). Injectable drug utilization patterns in these groups were analysed by demographics, diagnoses, and drug subgroups.
Results: Out of 13186 prescriptions, 70.8% were issued for NCDs. NCD prescriptions were mostly generated for women and elderly (p<0.05 for both). About 63.3% (n=2948) of injectable drugs in CD prescriptions were antibiotics and 12.6% were analgesics. Cefazolin (15.2%) was the most commonly prescribed antibiotic for acute pharyngitis and acute sinusitis, and benzathine benzylpenicillin (12.8%) was the top-choice for acute tonsillitis and rheumatic fever. In NCD prescriptions, 34.0% (n=4214) of injectable agents were analgesics and 16.9% were muscle relaxants. The most frequently encountered drug in NCD prescriptions was thiocolchicoside (16.3%), which was the top-choice in all seven common musculoskeletal diagnoses.
Conclusion: Muscle relaxants and analgesics were the most commonly prescribed injectable drugs for NCDs, musculoskeletal diseases in particular. Antibiotics were frequently encountered in CD prescriptions, mostly as broad-spectrum for lower respiratory tract infections (RTIs) and narrow-spectrum for upper RTIs. These findings may elucidate the issues to especially focus on regarding excessive use of injections.

Published: April 2023

The study examined Finnish early childhood education professionals’ (ECEP) (n = 107) experiences of occupational well-being and systems intelligent teamwork. Occupational well-being was measured with basic psychological job satisfaction, work engagement and burnout. In the analysis of variances by rank, the ECEPs’ had high work engagement, felt competent and relatedness in a working community. By contrast, their autonomy was low, and they felt exhausted, even though the overall burnout level was low. Extensive working experience increased work-related well-being and perceiving socioemotional systems in work. The ECE teachers had the highest work engagement, basic psychological need satisfaction and lowest burnout, but didn’t feel strongly competent in perceiving systemic interaction structures. On the other hand, the ECE social pedagogues felt most competent in systems intelligence behavior. The ECE childcarers valued the support of the systems intelligence team. In the cluster analysis, we identified two different clusters representing the level of occupational well-being and systems intelligence. The solution presented a connection between the ECE teachers with high work-related well-being and systems intelligence. We suggest that the multi-professional teamwork should be developed according to the ECEPs’ diverse educational background and that professional responsibilities be made more consistent with their education.

Kepemimpinan Kepala Madrasah merupakan suatu aspek yang memiliki pengaruh yang sangat besar dalam proses pendidikan di Madrasah. Kepala Madrasah sebagai pemimpin harus berupaya mengembangkan pengetahuan dan keterampilanya dalam mengolah perubahan yang terjadi di Madrasah. Kepala Madrasah adalah sebagai otak untuk berpikir tentang masa depan Madrasah, sebagai mulut untuk berbicara mengeluarkan perintah untuk menggerakkan bawahannya, dan sebagai mata untuk melihat dan mengawasi apakah proses pendidikan di Madrasah berjalan dengan lancar. Begitu juga dengan Kepala Madrasah MI Hidayatul Mubtadiin Rowotamtu Rambipuji Blokagung adalah orang yang berperan sentral terhadap pembentukan karakter peserta didiknya. Kepala Madrasah berharap agar akhlakul karimah yang mencerminkan karakter islami menjadi perangai peserta didiknya. Bagaimana Kepala Madrasah menjalankan kepemimpinannya untuk mewujudkan hal tersebut menjadi hal yang perlu untuk dikaji lebih mendalam. Karena kepemimpinan Kepala Madrasah di dalam suatu lembaga pendidikan mempunyai pengaruh terhadap pembentukan karakter peserta didiknya.

Buying and selling online is currently carried out without meeting directly between the seller and the buyer. Instead, it is done online by providing pictures of descriptions and descriptions of goods to buyers through social media and marketplace applications. So that in practice the buyer only sees a description of the sales he will buy and the buyer cannot see directly the goods he will buy so that it is most likely that when the goods arrive in the hands of the buyer, the picture seen before does not match the goods received. This study aims to determine the law of buying and selling online in the Islamic legal system and the differences between buying and selling in the past and present. This type of research is library research. This research is descriptive in nature and the data collection method uses library research techniques. Data from friends is described descriptively and analyzed using a deductive way of thinking. The results of the study show that buying and selling online is permissible and legal to use. The difference between buying and selling then and now lies in the clarity of the bargaining process used.

Introduction

Lung adenocarcinoma progresses stepwise from atypical adenomatous hyperplasia to adenocarcinoma in situ (AIS), followed by minimally invasive adenocarcinoma (MIA), and then obvious invasive adenocarcinoma. In this study, we examined the protein expression profiles of early and epidermal growth factor receptor (EGFR) mutation‐positive lung adenocarcinomas.

Methods

Fifteen cases of small and EGFR mutation‐positive adenocarcinomas were collected, including AIS, MIA, and small invasive adenocarcinoma (SIA). We examined their protein expression profiles by tandem mass tag (TMT)‐labeling liquid chromatography‐mass spectrometry (LC–MS/MS) and compared the results between AIS and MIA versus SIA. The differentially expressed proteins were then verified by Western blot analysis and immunohistochemistry (IHC). The clinicopathological implications of the proteins were also examined by IHC.

Results

A total of 4220 proteins were identified by LC–MS/MS analysis. Pathway analysis of the differentially expressed proteins revealed that pathways related to interferon α/β signaling, glutamate and glutamine metabolism, and gluconeogenesis were upregulated in SIA relative to AIS. Among the 13 differentially expressed proteins, cellular retinoic acid binding protein 2 (CRABP2), delta(24)‐sterol reductase (DHCR24), and adenylate kinase 4 (AK4) were expressed significantly more strongly in SIA than in AIS. Patients with high expression of CRABP2, DHCR24, and AK4 showed a significantly poorer outcome than those with low expression.

Conclusion

In comparison with AIS, SIA shows differences in several different protein expression pathways. Furthermore, CRABP2, DHCR24, and AK4 are useful IHC markers for diagnosis of lung adenocarcinoma invasiveness and may be associated with malignant progression of AIS.

Purpose

To investigate the value of ultrasound and serum marker tests in detecting lateral lymph node metastasis in medullary thyroid cancer (MTC).

Methods

Data of 105 patients diagnosed with MTC and admitted to the Department of General Surgery in Peking Union Medical College Hospital from June 2010 to August 2020 were collected and retrospectively analyzed.

Results

Ultrasound examination alone had a sensitivity of 89.36% and a specificity of 70.69%. For surveillance of postoperative carcinoembryonic antigen and calcitonin, cut‐off values of 7.115 ng/mL and 13.185 pg/mL, respectively, were shown to discriminate the presence of cervical lymph node metastasis. Combining ultrasound and postoperative serum levels of both carcinoembryonic antigen and calcitonin as serial tests increased the specificity to 91.38% and 87.93%, with a sensitivity of 95.45%. Multivariate logistic analysis identified the following risk factors for lateral lymph node metastasis in MTC: suspicious lymph nodes detected by ultrasound and postoperative calcitonin above 13.185 pg/mL.

Conclusion

The combination of ultrasound and serological tests achieved higher sensitivity and specificity to identify MTC cases with potential occult lateral cervical lymph node metastasis compared with single tests.

Sodium‐carbon dioxide (Na‐CO2) batteries are regarded as promising energy storage technologies because of their impressive theoretical energy density and CO2 reutilization, but their practical applications are restricted by uncontrollable sodium dendrite growth and poor electrochemical kinetics of CO2 cathode. Constructing suitable multifunctional electrodes for dendrite‐free anodes and kinetics‐enhanced CO2 cathodes is considered one of the most important ways to advance the practical application of Na‐CO2 batteries. Herein, RuO2 nanoparticles encapsulated in carbon paper (RuCP) are rationally designed and employed as both Na anode host and CO2 cathode in Na‐CO2 batteries. The outstanding sodiophilicity and high catalytic activity of RuCP electrodes can simultaneously contribute to homogenous Na+ distribution and dendrite‐free sodium structure at the anode, as well as strengthen discharge and charge kinetics at the cathode. The morphological evolution confirmed the uniform deposition of Na on RuCP anode with dense and flat interfaces, delivering enhanced Coulombic efficiency of 99.5% and cycling stability near 1500 cycles. Meanwhile, Na‐CO2 batteries with RuCP cathode demonstrated excellent cycling stability (>350 cycles). Significantly, implementation of a dendrite‐free RuCP@Na anode and catalytic‐site‐rich RuCP cathode allowed for the construction of a symmetric Na‐CO2 battery with long‐duration cyclability, offering inspiration for extensive practical uses of Na‐CO2 batteries.
