Objective: The chest radiograph (CXR) is the predominant imaging investigation being used to triage patients prior to either performing a SARS-CoV-2 polymerase chain reaction (PCR) test or a diagnostic CT scan, but there are limited studies that assess the diagnostic accuracy of CXRs in COVID-19. To determine the accuracy of CXR diagnosis of COVID-19 compared with PCR in patients presenting with a clinical suspicion of COVID-19. Methods and materials: The CXR reports of 569 consecutive patients with a clinical suspicion of COVID-19 were reviewed, blinded to the PCR result and classified into the following categories: normal, indeterminate for COVID-19, classic/probable COVID-19, non-COVID-19 pathology, and not specified. Severity reporting and reporter expertise were documented. The subset of this cohort that had CXR and PCR within 3 days of each other were included for further analysis for diagnostic accuracy. Results: Classic/probable COVID-19 was reported in 29% (166/569) of the initial cohort. 67% (382/569) had PCR tests. 344 patients had CXR and PCR within 3 days of each other. Compared to PCR as the reference test, initial CXR had a 61% sensitivity and 76% specificity in the diagnosis of COVID-19. Conclusion: Initial CXR is useful as a triage tool with a sensitivity of 61% and specificity of 76% in the diagnosis of COVID-19 in a hospital setting. Advances in knowledge: . Diagnostic accuracy does not differ significantly between specialist thoracic radiologists and general radiologists including trainees following training. There was a 40% prevalence of PCR positive disease in the cohort of patients (n = 344) having CXR and PCR within 3 days of each other. Classic/probable COVID-19 was reported in 29% of total cohort of patients presenting with clinical suspicion of COVID-19 (n = 569). Initial CXR is useful as a triage tool with a sensitivity of 61% and specificity of 76% in the diagnosis of COVID-19 in a hospital setting

Authors: Zhang Guiling , Wei Wei , Tan Bo , Liu Jingqin 
Published: July 2020

Objective: To discuss the correlation between hormone levels and cardiovascular autonomic neuropathy (CAN) in menopausal patients with Type-2 diabetes mellitus (T2DM).
Methods: This clinical research study was conducted at Department of Endocrinology, Baoding No. 1 Hospital from January 2016 to December 2017. In this study a total of 386 menopausal female patients with T2DM were selected and classified into two groups according to the CAN function test: the CAN group (80 cases) and the DM group (306 cases). The Kupperman score (KI integral) was calculated for all participants in the study, and the following indexes were measured: body mass index (BMI), blood estrogen (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid-stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), fasting blood-glucose (FBG), glycosylated hemoglobin (HbA1c), serum lipids, uric acid (SUA), hypersensitive c-reactive protein (CRP), etc.
Results: The FBG, HbA1c, TGs, Hs-CRP, SUA, KI score, TSH, FSH and LH of the CAN group were obviously higher than the same parameters in the DM group (P﹤0.01, P﹤0.05), while HDL-C, E2, FT3 and FT4 were significantly lower (P﹤0.01, P﹤0.05). Pearson correlation analysis indicated that CAN presents a positive correlation with HbA1c, TGs, hs-CRP and SUA and a negative correlation with HDL-C and E2, and the difference was statistically significant (P<0.05). The multifactor logistic regression analysis results showed that HbA1c (OR=3.980, 95%CI=1.268~10.319) and E2 (OR=3.075, 95%CI=1.167~7.366) are independent risk factors for CAN.
Conclusion: The CAN morbidity of menopausal female patients with T2DM is high, and HbA1c and E2 should be mainly monitored to identify and treat CAN early.

Bed side teaching: Student’s perception and its correlation with academic performance
Authors: Sarwar Shahid , Aleem Abdul , Nadeem Muhammad Arif 
Published: July 2020

Objective: To determine student’s perception of bedside clinical teaching and to correlate it with their performance in assessment.
Methods: This cross-sectional study of correlational survey was conducted at Services Institute of Medical Sciences in September 2019, involving students of final professional year who filled a proforma to rate their bedside teaching experience during clinical rotations using rating scale. Mean scores of items were determined with score < 3 reflecting dis-satisfaction. Mean scores were compared between high and low performing students using student’s t test.
Results: Total of 160 students participated. Physical environment domain was assigned lowest scores by students (mean 2.94±0.74) followed by teaching task by teachers (3.04±0.72), group dynamics (3.16±0.81) and patient comfort and attitude towards patient (3.87±0.60). Teaching task by teacher had maximum stems with scores < 3 needing significant improvement. Students with low academic performance were more unsatisfied with group dynamics of bedside teaching (p value 0.009), especially lack of equal opportunities of participation for every member (p value <0.000) in clinical rotations.
Conclusion: Small size group with adequate space for bedside training and faculty training can enhance learning experience of students. Ensuring active participation of each group member during bedside learning can improve academic performance of students.

Precision in-cylinder H2O vapor absorption thermometry and the associated uncertainties
Authors: Janecek D. , Melin S. , Sanders S. , Rothamer D. , Ghandhi J. 
Published: July 2020

Water vapor absorption spectroscopy was used to measure crank-angle resolved temperature in an internal combustion engine for two intake pressures and a range of intake temperatures from 323 to 423 K. Measurements were acquired throughout the full engine cycle, for both motored and fired operating conditions. The methodology to convert absorbance measurements to processed temperatures up to values of 650 K are detailed in this work. The sensitivity of the processed temperature to the processing parameters was analyzed and quantified. The precision of the sampled mean with 95% confidence uncertainty bounds was 0.5%, and a comparison of the temperature estimates using the band shape thermometry technique was compared to both fast-response thermocouple measurements as well as a trapped-mass thermodynamic model.

Published: July 2020

The article analyzes important meaning of determining the advantages and threats of choosing a dominant domestic (constitutional) or external (international treaties) vector of budgetary funds administration to ensure the certainty of the development direction of the financial, economic and legal system of the states that are still in the stage of formation. The resolution of this task is an integral part of the characteristics of the state’s basic functioning, with the determination of the primacy of the respective sources regulation.
The study uses general scientific and special scientific methods, the basis of which is the application of the results of theoretical studies, statistical and other generalized information on the functioning of the legal and financial system of Ukraine. Ukraine recognizes the primacy of international legal regulation, however, if it does not contradict the Constitution.
In the context of globalization and threats to identity, special measures shall be applied by the state to protect its financial stability and independence. It is stated in the article that special attention should be paid to normative principles, which shall be reflected in the legislation. Moreover, the article analyzes the acts of soft law in the framework of cooperation with international financial organizations, which differ from ‘ordinary’ treaties, but bear a politically binding component. It is concluded that the international obligations of the state, taken under international treaties in the financial and budgetary sphere, cannot create direct consequences for citizens, but must be realized in the legal system through national law-making.
Fully Affine Invariant Methods for Cross-Session Registration of Calcium Imaging Data
Authors: Li Chunyue , Yang Xiaofeng , Ke Ya , Yung Wing-Ho 
Published: July 2020

AbstractIn vivotwo-photon microscopy permits simultaneous recording of the activity of the same neuronal population across multiple sessions in days or weeks, which is crucial for addressing many fundamental questions of neuroscience. The field-of-view (FOV) alignment is a necessary step for identifying the same neurons across multiple imaging sessions. Accurate FOV alignment becomes challenging in the situations of image blurring, insufficient common neurons, or uneven background brightness. The existing methods largely fail to align FOV pairs in these situations. The fully affine invariant approach has been applied in computer vision to register real scene images with different backgrounds. However, its performance in calcium imaging data is unknown. We explored the feasibility of using the fully affine invariant approach to align calcium FOV images across multiple sessions by examining the performance of five methods. Further, we compared their performance with common feature-based methods as well as some classical methods with or without adaptive contrast enhancement. Using cellular resolution calcium imaging data recorded from two areas of the mouse motor cortex over weeks, we show that all fully affine invariant methods provide more accurate FOV alignment results than other methods in general and in the case of a few common neurons identified, uneven background brightness or image blurring. This study demonstrated the feasibility and reliability of the fully affine invariant methods in cross-session FOV alignment. These methods could be useful for neuroscience research, especially on questions that involve experience-dependent plasticity spanning over days or weeks.

Published: July 2020

AbstractBackground and aimsThe working memory (WM) ability of internet addicts and the topology underlying the WM processing in internet addiction (IA) are poorly understood. In this study, we employed a graph theoretical framework to characterize the topological properties of the IA brain network in the source cortical space during WM task.MethodsA sample of 24 subjects with IA and 23 matched healthy controls (HCs) performed visual 2-back task. Exact Low Resolution Electromagnetic Tomography was adopted to project the pre-processed EEG signals into source space. Subsequently, Lagged phase synchronization was calculated between all pairs of Brodmann areas, the graph theoretical approaches were then employed to estimate the brain topological properties of all participants during the WM task.ResultsWe found better WM behavioral performance in IA subjects compared with the HCs. Moreover, compared to the HC group, more integrated and hierarchical brain network was revealed in the IA subjects in alpha band. And altered regional centrality was mainly resided in frontal and limbic lobes. In addition, significant relationships between the IA severity and the significant altered graph indices were found.ConclusionsIn conclusion, these findings provide evidence to support the notion that altered topological configuration may underline changed WM function observed in IA.

AbstractBackground and aimsExcessive use of electronic devices has become a major global problem. However, little is known about the development and current landscape of research concerning this field. This study aimed at exploring the overall publication trend and topics of research on the overuse of electronic devices and the Internet from 1971 to 2017.MethodsWe systematically searched the Web of Science (WoS) and Scopus databases for published articles on the excessive use of electronic devices and the Internet. Data regarding the publication volume, international collaborations, and geographical locations were analyzed by bibliometrics analysis. Latent Dirichlet Allocation (LDA) was undertaken to categorize publications into different research topics.ResultsA total of 2,276 papers from the WOS and 600 papers from the Scopus were included. We found a dramatic increase in the number of scientific papers towards addiction to electronic devices and the Internet. The United State led in all publication parameters including the total number of papers and total citations. China, Korea and Taiwan were among the most prolific countries/regions. Smartphone addiction was the main concern, and the relationship between the overuse of electronic devices and the Internet and mental health issues have been highlighted. On the other hand, our study found a limited appearance of discussion on effective treatment and intervention.Discussion and ConclusionThe findings of this study call for more national and international cooperation in evaluating and intervening addiction to electronic devices and the Internet to gather more knowledge about this phenomenon and evaluate the effectiveness of treatment.

A study of effect of aminoglycoside therapy on auditory brainstem evoked responses in preterm and term neonates
Authors: Kumar Mukesh , Parakh Manish , Dabi D. R. , Gupta B. D. 
Published: July 2020

Background: Aminoglycosides are widely used drugs in neonates with associated ototoxic side effects, that can be diagnosed with auditory brainstem evoked responses, which is the recommended screening technique in neonatal intensive care unit infants. This study was conducted to evaluate the effect of aminoglycoside therapy on auditory brainstem evoked responses in term and preterm neonates.Methods: A cross-sectional case control study. Two groups of 26 term and 22 preterm neonates who received aminoglycosides, with no other known risk factors for ototoxicity, were compared with suitable matched control group of 10 neonates in each. ABER was done after at least 5 days of aminoglycoside therapy and results were compared to suitable matched controls.Results: Mean latency of wave I in term neonates at 90 dB and 60 dB and mean interwave latencies of I-V waves in preterm neonates at 30 dB was higher in study group and statistically significant. No statistically significant difference in any of ABER parameters was observed in any group, at all other intensities.Conclusions: Wave I latency was prolonged in study group of term neonates at two intensities which indicates effect of aminoglycoside therapy on distal portion of acoustic nerve. But as there were no such findings at other intensities in term study group and in preterm study group and moreover no other ABER abnormalities were observed, it was concluded that the aminoglycoside therapy has low potential for ototoxicity. Authors support the ABER screening for early detection of hearing abnormalities, and recommend study on larger group of neonates and meta-analysis for final conclusion for evidence-based recommendations to use aminoglycosides in neonates, in view of audiometric and neurological abnormalities.

Los materiales liberados en Costa Rica a la fecha para el cultivo de arroz (Oryza sativa L.) no reciben una distinción en el manejo por parte de los productores del Pacífico Central y Zona Sur de Costa Rica, a pesar de la alta variabilidad del nivel de macollamiento y de la capacidad productiva. Para determinar el efecto de diferentes densidades de siembra y diferentes niveles de fertilización sobre el rendimiento de arroz, se realizó un ensayo en finca La Ligia, en Parrita, Puntarenas. El diseño experimental fue de bloques completos al azar con tratamientos y tres repeticiones para cada una de las variedades (Palmar 18, Lazarroz FL y NayuribeB FL); los tratamientos consistieron en tres densidades de siembra (75, 115 y 155 kg/ha de semilla) y 3 niveles de fertilización de N-P-K (50-50-50, 100-50-0, 100-50-100 kg/ha). Las variables evaluadas fueron rendimiento (ton/ha SL), número de macollos / planta, número de panículas / m², cantidad de granos llenos y peso de 1000 granos; todo lo anterior evaluado en la cosecha del I ciclo de secano correspondiente al año 2017. Para todos los tratamientos se encontraron respuestas significativas. La densidad de siembra de 3,37 qq / ha de semilla favoreció los mejores rendimientos para todas las variedades. Estas además mostraron mejor rendimiento luego de suministrar 100-50-100 kg/ha de fertilizante, y Lazarroz FL fue la variedad que alcanzó los mejores rendimientos (ton/ha SL), seguida de NayuribeB FL y de Palmar 18.

Abstrak

During these curriculum development has been widely discussed at the regular school level, starting from the lowest level to the top. But many of them include inclusive schools that have not been studied in curriculum development. Especially related to Islamic Education (PAI) subjects at Inclusive Middle School level. This situation will greatly affect the education system at that level starting from Educators, students, stakeholders and the community. Therefore the development of the Islamic Religious Education curriculum in Galuh Handayani Inclusive Middle School can be used as an example of a curriculum development model for the sake of advancing education in Indonesia

Selama ini pengembangan kurikulum banyak dibicarakan di tataran sekolah regular mulai jenjang yang paling bawah hingga keatas. Namun banyak diantaranya sekolah inklusif yang belum diteliti pengembangan kurikulumnya. Apalagi berkaitan dengan mata pelajaran Pendidikan Agama Islam (PAI) di tingkat SMP Inklusif. Situasi ini akan sangat mempengaruhi sistem pendidikan ditingkat tersebut mulai Pendidik, peserta didik, stakeholder dan masyarakat. Oleh sebab itu pengembangan kurikulum Pendidikan Agama Islam di SMP Inklusif Galuh Handayani bisa dijadikan contoh model pengembangan kurikulum untuk kepentingan kemajuan pendidikan di Indonesia
