Purpose:The Covid-19 pandemic has affected our daily lives by affecting the whole world and caused our habits to change.One ofthe effects of the epidemic has been on education.With the spread of the epidemic, online education has become the only way to maintain the normal teaching order.In this case, it directly affects the quality of education received.The aim of this study is to examine whether there is a difference between the exam scores made face to face and online. Methods:Students who were 3rd grade in 2018-2019 and 4th grade in 2019-2020 academic year were included in the study.Thescores that these students got in the Pedodontics Theoretical Exam within two years were evaluated. Exam scores according to time were analyzed with Friedman Test and Wilcoxon Test. Results:In the 2019-2020 academic year, the median values of the scores obtained from the exams that took the first examface-to-face and the second and third exams online varied (p<0.001).The median values of the scores obtained in the online exams(median values of 90 and 95, respectively) (the mean values are 89.6±8.7, 93.8±9, respectively), the median values of the scores obtained from the theoretical exam (median 70, mean 67.2±18.1) was obtained higher.On the other hand ,it was observed that there was a significant increase between the scores obtained by the same students from the exams held face-to-face in the previous year(median 74, mean 74.1±7.1) and the scores they took from the online exams they obtained the next year (median 89, mean87.7±9.1)(p<0.001). Conclusion:The results of the exams made with the online system are higher than the exam scores performed face to face.Thismay be due to the insufficient control mechanisms of the online exam system.For this reason, online exam security measuresshould be increased.

Proper peer review and quality of published articles are often regarded as signs of reliable scientific journals. The aim of this study was to compare whether the quality of statistical reporting and data presentation differs among articles published in ‘predatory dental journals’ and in other dental journals. We evaluated 50 articles published in ‘predatory open access (OA) journals’ and 100 clinical trials published in legitimate dental journals between 2019 and 2020. The quality of statistical reporting and data presentation of each paper was assessed on a scale from 0 (poor) to 10 (high). The mean (SD) quality score of the statistical reporting and data presentation was 2.5 (1.4) for the predatory OA journals, 4.8 (1.8) for the legitimate OA journals, and 5.6 (1.8) for the more visible dental journals. The mean values differed significantly (p < 0.001). The quality of statistical reporting of clinical studies published in predatory journals was found to be lower than in open access and highly cited journals. This difference in quality is a wake-up call to consume study results critically. Poor statistical reporting indicates wider general lower quality in publications where the authors and journals are less likely to be critiqued by peer review.

Background:Boolean remission criteria is one most popular and stringent criteria in treating patient with rheumatoid arthritis (RA), because it may guarantees a stable clinical course after attaining remission.Objectives:Impact of time span from initiation to achieving Boolean remission on maintaining disease activity, daily activities, and quality of life after attaining Boolean remission was investigated from daily clinical practice data.Methods:685 patients with RA since August 2010 under the T2T strategy were treated. They were monitored for their TJC, SJC, PGA, EGA, CRP, and disease activity indices such as CDAI, SDAI, DAS28, and Boolean criteria at every visit. HAQ-DI score, pain score using visual analog scale (PS-VAS), and EQ-5D were also monitored, and the quality of life score (QOLS) calculated from EQ-5D was determined at every visit from the time of diagnosis (baseline).Of 685 patients, 465 patients had achieved Boolean remission >1 times, and were consecutively followed up for >3 years. These patients were enrolled in the study. Time span from the first visit to first Boolean remission was calculated. The relationship between the time span and each of background parameters, and the relationship between the time span and each of the mean values of the SDAI score, HAQ score, PS-VAS, SHS, and QOLS at the first Boolean remission and thereafter was evaluated statistically.Patients were subsequently divided into the G ≤ 6 and G > 6 groups based on the achievement of first Boolean remission within two groups: time span G ≤ 6 months and G > 6 months. The two groups were compared with regard to the SDAI score, HAQ score, PS-VAS, SHS, and QOLS at first visit and at the time of first Boolean remission, and the mean values of these parameters after remission were evaluated statistically. Moreover, changes of these parameters and the mean Boolean remission rate after the first remission, and SDAI remission rate at the first Boolean remission to thereafter were compared between the two groups statistically.Results:Out of 465 patients, females comprised 343 (73.7%), and the mean age was 67.8 years (range, from 21–95 years). The mean disease duration at first visit was 6.1 years (range, from 1 months–45 years). The mean follow up length was 88.1 months (range: 36–122 months; median: 85 months) and mean time span from the first visit to the first Boolean remission was 8.1 months. The mean SDAI score, HAQ score, PS-VAS, and the QOLS at first visit were 13.3, 0.467, 33.2, and 0.834, respectively. Among the study parameters, PS-VAS and QOLS were significantly correlated with the time span. For parameters at the first Boolean remission, HAQ-DI score, PS-VAS, and QOLS demonstrated significant correlation with the time span, whereas SDAI, HAQ-DI score, PS-VAS, SHS, and QOLS after the Boolean remission demonstrated significant correlation with the time span.The comparison between the G ≤ 6 and the G > 6 groups revealed that the disease duration, HAQ score, and PS-VAS at baseline in the G > 6 were significantly higher than that in the G ≤ 6 group, and QOLS in the G ≤ 6 group was significantly higher than that in the G > 6 group at baseline. Similarly, the HAQ score and PS-VAS at the first Boolean remission in the G > 6 group were significantly higher than that in the G ≤ 6 group, whereas QOLS in the G ≤ 6 group demonstrated no significant difference compared with that in the G > 6 group.The mean value of the SDAI score after the first Boolean remission in the G > 6 group was significantly higher than that in the G ≤ 6 group. Similarly, the SDAI score, HAQ score, and PS-VAS after the first Boolean remission in the G > 6 group were also significantly higher than those in the G ≤ 6 group, and the mean value of the QOLS in the G ≤ 6 group were significantly higher than that in the G > 6 group. The Boolean remission rate and SDAI remission rate after the first Boolean remission were significantly higher in the G ≤ 6 group than those in the G > 6 group.Conclusion:Attaining Boolean remission ≤ 6 months for RA has significant benefit for more stable disease control, that leads good maintenance of ADL.Disclosure of Interests:None declared

We live in a society in which mobile and digital technologies are increasingly present in our daily lives and we cannot limit ourselves to knowing how to use them. It is important to know how to adapt them, personalize them and program them, if necessary, to solve our problems. Computational thinking is understood as the human ability to teach, humans or machines, to solve problems with the fundamentals of computing. Its development has gained space in education, formal and non-formal, through face-to-face practices. With the pandemic, the challenge arises to develop this skill with young people from high school in a public educational institution through online practices. In this article, we discuss the didactic design, based on the principles of online education, created for the development of computational thinking with online practices. The preliminary results indicate the feasibility of developing computational thinking from the perspective of online education.

ABSTRACT: Crambe is a rapeseed with high oil content and can be used as a winter cover or as a source of raw material for the production of biodiesel, however espite the growing interest in the culture, research on the subject is still incipient, especially concerning the seed production and analysis technology. The purpose of this study is to evaluate the physiological quality of crambe seeds, 'FMS Brilhante' cultivar, by testing the pH of exudate. Five seed lots were submitted to the determination of water content and the tests of germination and vigor (first count, emergence and tetrazolium). In the conduction of pH exudate test, temperatures (25 and 30oC), and periods of seed imbibition in water (15, 30 and 45 minutes) were tested. The experiment was conducted in a completely randomized manner, with four replicates, and the mean values were compared by the Tukey test at 5% probability; Pearson correlation between the pH of the exudate and initial tests was also made. Testing the pH of exudate is promising for separating lots of crambe seeds and the following combinations of 25°C/30 minutes or 30°C/45 minutes can be used.

An investigation was undertaken to compare the relative magnitudes of the differential effects of environment (i.e., stations) and of malting methods on the malting quality of barley varieties. Samples of Olli, O.A.C. 21, Hannchen, and Regal from four stations were malted by eight methods representing the combinations of germinating at 50° and 56° F., at 42 and 46% moisture, and for six and nine days.Statistical analyses showed that, with respect to diastatic activity, wort nitrogen, and extract yield, the variations due to the differential effect of environment on varieties were greater than the variations due to the differential effect of malting methods on varieties. As a result of this study and earlier ones, it appears that the former effect is the limiting factor in studies of the comparative malting qualities of varieties. The latter effect is of less importance but must be kept in mind if errors in the interpretation of the results of routine tests are to be avoided. In general, it appears that if routine tests show that the mean values for any variety, when grown at 12 stations representing a reasonable range of environment, differ from the values for the standard variety by more than 1% in extract, or 10% in diastatic activity or wort nitrogen, a real difference exists between the varieties, which cannot be overcome by any reasonable change in malting conditions.

The outbreak of Corona Virus Disease 2019 (COVID-19) in various countries at the end of last year has transferred traditional face-to-face teaching to online education platforms, which directly affects the quality of education. Taking user satisfaction on online education platforms in China as the research object, this paper uses a questionnaire survey and web crawler to collect experience data of online and offline users, constructs a customer satisfaction index system by analyzing emotion and the existing literature for quantitative analysis, and builds aback propagation (BP) neural network model to forecast user satisfaction. The conclusion shows that users’ personal factors have no direct influence on user satisfaction, while platform availability has the greatest influence on user satisfaction. Finally, suggestions on improving the online education platform are given to escalate the level of online education during the COVID-19 pandemic, so as to promote the reform of information-based education.

The aim of this study was to assess the periodontal condition and the presence of putative periodontal pathogens in 30 Brazilian mothers, aging 21-40 years (28.4 ± 4.49 years), and in their children, aging 5-6 years, since mothers can be a source of pathogens and, thus, influence their children's bacteriological and clinical condition. Besides assessing the plaque index (PI), gingival index (GI) and pocket probing depth (PD), the survey analyzed four subgingival dental plaque samples from mothers and children, as well as a sample of stimulated saliva from mothers. Those samples were analyzed by means of the slot immunoblot (SIB) technique, in order to determine the presence of Actinobacillus actinomycetemcomitans (Aa), Prevotella nigrescens (Pn), Porphyromonas gingivalis (Pg) and Treponema denticola (Td). The mean values and standard deviations of the evaluated clinical variables for mothers and children were, respectively: 1.86 ± 0.67 and 1.64 ± 0.68 for PI, and 1.24 ± 0.67 and 0.82 ± 0.37, for GI. Only for mothers, the total PD was 1.81 ± 0.69 mm, and the PD of four sites was 4.03 ± 1.40 mm. The Wilcoxon test revealed significant difference (p < 0.05) between mothers and their children only as to GI. The most prevalent bacteria in mothers were, in decreasing order: Aa, Pn, Pg and Td. The children presented patterns of oral hygiene and bacterial profiles similar to those of their mothers, in spite of the fact that most of them did not present enough subgingival plaque for testing. The comparison between mothers' subgingival dental plaque and saliva samples revealed statistically significant differences (p < 0.05) for all bacteria, with greater positivity and scores in the saliva, which demonstrates that it is an indicator of oral colonization and can work as a vehicle for the transmission of periodontopathogens from mothers to their children.

At the moment the suitability of stored red blood cells (sRBC) for transfusion is checked by routine methods such as haemoglobin estimation and the level of haemolysis. These methods cannot characterize directly the quality of the membranes of sRBC. The aim of this work is to assess the quality of sRBC based on such criteria as the membrane’s stiffness and the size and the form of sRBC. Materials and Methods. We have investigated 5 series of dry cytosmears of the sRBC which had been kept in blood bank in a period from 1 to 35 days. After AFM imaging, in every specimen, 5 RBC were chosen at random; the diameter, the height, and the stiffness were measured on each of them. Results. The present study shows high increase of the mean values of YM and height of RBC after 35 days of storage and decrease of the mean values of their diameter. Conclusion. Statistically significant high increase of the mean values of YM indicates the decrease of the elasticity of the cells in the course of storing of the RBC. This parameter along with the morphological characteristics can be used as criterion for assessment of applicability of the sRBC for blood transfusion.

<strong>Introduction:</strong> The satisfaction level with health care reflects the quality of care from the patient’s perspective. The aim of this study is to assess patient satisfaction with anesthesia care in a Portuguese general hospital by using the “The Heidelberg Peri-anaesthetic Questionnaire”.<br /><strong>Material and Methods:</strong> The questionnaire was translated and tested based on psychometric quality criteria in a sample of 107 patients who underwent elective surgery as inpatients at Hospital de São João. The global satisfaction and for each dimension of care were calculated. We analyzed the differences between patients with different levels of satisfaction, identifying potential confounding factors.<br /><strong>Results:</strong> The Portuguese version of the questionnaire has 32 items distributed in three dimensions: ‘staff’, ‘discomfort’ and ‘fear’. The mean values of satisfaction for each dimension were 83.4%, 66.8% and 65.9%, respectively. The internal consistence was demonstrated by a Cronbach’s alpha coefficient ranging from 0.776 to 0.875 in the three dimensions. Satisfied and dissatisfied patients differed in the three dimensions, but to a lesser degree in ‘staff’. In the multivariate analysis we found significant influence of gender in the ‘discomfort’ dimension.<br /><strong>Discussion: </strong>The questionnaire has good psychometric characteristics. The domain ‘staff’ includes three domains of the source questionnaire.<br /><strong>Conclusions:</strong> Its application revealed high satisfaction levels regarding the staff. Dissatisfaction was mainly seen in the “fear” and “discomfort” dimensions, the latter being significantly lower in males.

Real Patients

In our medical school, we changed from a lecture-based method to a team-based learning (TBL) method to teach “polyneuropathies” in the neurology clerkship starting from the 2014 to 2015 academic year. Real patients were used instead of written scenarios in TBL sessions. This study aimed to compare former lecture-based and the current TBL methods in terms of knowledge retention, in-class learner engagement, and learner reactions. First, we determined in-class engagement and satisfaction of the students for the lectures given in the 2013–2014 academic year. The following year, besides the same criteria, we also determined individual (IRAT) and group readiness test (GRAT) scores in the TBL group. End-of-clerkship exam scores for both groups were recorded. Additionally, opinions of patients about their experiences throughout the TBL process were determined. One year later (2015 for lecture and 2016 for TBL), both groups sat for an MCQ test to determine their knowledge retention levels. We found no difference between groups regarding end-of-clerkship exam scores. The mean knowledge retention test score of the TBL group was significantly higher than that of the lecture group (5.85 ± 1.74 vs. 3.28 ± 1.70). The differences between IRAT, GRAT, and retention test scores in the TBL group were significant. The mean student satisfaction score on a five-point scale was 3.01 ± 0.9 (median = 3) in the lecture group and 4.11 ± 1.1 (median = 4) in the TBL group. Our results seem encouraging for use of TBL performed with real patients in neurology education to achieve better long-term knowledge retention and higher in-class engagement and student satisfaction.
