DOES SOCIAL NETWORK QUALITY DIFFER BETWEEN FACEBOOK AND INSTAGRAM? APPLICATION OF SNSQUAL MODEL

Although numerous studies investigated service quality in online environment, the social network quality has been inadequately captured by previous empirical research. Thus, the present study focuses on measuring social network quality. Specifically, it aims to examine potential differences in perceived social network quality between two popular social networks, namely Facebook and Instagram. The empirical data are based on gathering primary data using questionnaire based on SNSQUAL model, developed by Phillips et al. (2016). Descriptive and bivariate statistical analysis were conducted using data collected from undergraduate and graduate students who use social networks on regular bases. The study results show significant differences in 16 out of 27 social network quality items, revealing that Instagram’s social network quality was rated significantly higher than Facebook’s. These findings may contribute to the development of service excellence approach that aims to enhance social networks’ performance.

Predictive Factors for Cardiopulmonary Resuscitation Failure

Objectives: Patients with chronic diseases are often admitted to the hospital through the emergency room of the hospital because of complaints of dyspnoea, urinary retention, decreased consciousness and cardiac arrest requiring resuscitation. The purpose of this study is to find predictive factors for failure of cardiopulmonary resuscitation (CPR) in patients of chronic diseases. Materials and Methods: This cross-sectional study took medical records of patients who were carried out from primary healthcare center in Yogyakarta from 2017 to 2019. Bivariate statistical analysis used Fisher’s exact test to determine the relative risk; if P < 0.25, then multivariate analysis with logistic regression continued with the backward method to obtain the odds ratio (OR). Results: The results indicate that cardiac arrest patients with sepsis are most likely to fail at CPR, whereas male patients are 9.1 times (OR 9.1); patients with acidosis, 8.1 times (OR 8.1); and patients with asystole heart rhythm, 7.8 times (OR 7.8, P < 0.05). We can conclude that male patients with sepsis, acidosis or asystole heart rhythm will almost certainly fail to receive resuscitation. Conclusion: Sepsis or septic shock, the male gender, acidosis, and asystole rhythm can be determinants of mortality in patients with chronic diseases who undergo CPR. It is necessary for one to test the application of the checklist or data from other hospitals and score the predictive factors to make the determination of the success of CPR easier.

Epidemiological Aspects of Maternal and Congenital Toxoplasmosis in Panama

In Panama, epidemiological data on congenital toxoplasmosis are limited, making it difficult to understand the scope of clinical manifestations in the population and factors that may increase the risk of infection. This study provides insight into the epidemiological situation of maternal and congenital toxoplasmosis in Panama and contributing information on the burden of this disease in Central America. Blood samples were collected from 2326 pregnant women and used for the detection of anti-T. gondii antibodies. A high seroprevalence (44.41%) was observed for T. gondii infection in pregnant women from different regions of Panama, with an estimated incidence rate of congenital toxoplasmosis of 3.8 cases per 1000 live births. The main risk factors associated with T. gondii infection using bivariate statistical analysis were an elementary level education and maternal age range of 34-45 years. Multivariate statistical analyses revealed that in some regions (San Miguelito, North and West regions), the number of positive cases correlated with the presence of pets, stray dogs and the consumption of poultry. In other regions (East and Metropolitan regions), the absence of pets was considered a protective factor associated with negative cases, while the presence of stray cats and the age range of 25–34 years did not represent any risk in these regions.

Evaluating the home isolation of COVID-19 patients in primary care

Background: This study aims to evaluate the effectiveness of home isolation and medical follow-up by analyzing data collected over the phone from isolated individuals. Methods: A cross-sectional phone-based survey designed to evaluate the home isolated COVID-19 suspected patients at the Şişli Hamidiye Etfal Family Health Center in Istanbul city between 16th March 5th May 2020. A semi-structured questionnaire and the universal sampling technique were recruited to collect data about the socio-demographic and the COVID-19 related laboratory and clinical findings. The SPSS for Windows program was used to perform a univariate and bivariate statistical analysis. The Statistical alpha significance level was accepted at less than 0.05. Results: A total of 463 confirmed, probable, or suspected cases of COVID-19 took part in this study with a mean age of 35.38 ∓17.1 (range: 0-86 years). Tow-third 310 (67.0%) underwent the PCR tests, and 67 (21.6%) confirmed positive results. Moreover, one-third (159, 34.3%) exposed to CT scans; however, 51(32.3%) were compatible with COVID-19. The median age of individuals with PCR positive was 38 years. More than half (40, 59.7%) were males, compared to 27 (40.3%) were females. There was no significant relationship between PCR positivity and pandemic period, age, or gender (P = 0.149; P = 0.545; P = 0.285), respectively. Although older individuals had a higher rate of CT scan compatible with COVID-19, the relation between increased age and COVID-19 compatible CT was found not to be statistically significant (P = 0.053). Moreover, there was significant relationship between CT scan positivity and coughing, the tobacco smoking and diabetes (P = 0.003; P = 0.032; P = 0.016), respectively. Conclusion: Combining PCR, symptoms, and CT together doubles the likelihood of a correct diagnosis. Quarantined patients must be regularly monitored.

From the bivariate analysis, it was found that there is a significant correlation between stress levels and the incidence of Pityriasis sicca. Conclusion: There is correlation between stress levels and the incidence of Pityriasis sicca in class 2017 students of the Faculty of Medicine, Universitas Sumatera Utara.

Self-collected oral, nasal and saliva samples yield sensitivity comparable to professional-collected oro-nasopharyngeal swabs in SARS-CoV-2 diagnosis

Introduction: Containment of the COVID-19 pandemic requires broad-scale testing. Laboratory capacities for real-time-PCR were increased, and are complemented by Ag-tests. However, sample-collection still requires qualified personnel and protective equipement, may produce transmission to others during conduct and travel, and is perceived uncomfortable. We tested sensitivity of three simplified self-sampling techniques compared to professional-collected combined oro-nasopharyngeal samples (cOP/NP). Methods: From 62 symptomatic COVID-19 outpatients, we obtained simultaneously three self- and one professional-collected sample after initial confirmation in a testing centre: (i) combination swab (tongue, cheek, both nasal vestibula, MS, (ii) saliva sponge combined with both nasal vestibula, SN, and (iii) gargled tap water, GW, (iv) professionally-collected cOP/NP (standard). We compared the results of SARS-CoV-2 PCR-assays detecting E-gene and ORF1ab for the different sample types and performed bivariate statistical analysis to determine the variables reducing sensitivity of the self-collecting procedures. Results: SARS-CoV-2 RNA was detected in all 62 professionally-collected cOP/NP. MS and SN samples showed a sensitivity of 95.2% (95%CI 86.5-99.0) and GW samples of 88.7% (78.1-95.3). Compared to the median ct-values of cOP/NP samples for E-gene (20.7) and ORF1ab (20.2) these were higher for MS (22.6 and 21.8), SN (23.3 and 22.3), and for GW (30.3 and 29.8). For MS and SN samples but not for GW specimens, false negativity in bivariate analysis was associated with non-German mother-tongue, number of sampling errors, and with symptom duration. For symptom duration of ≤8 days, test sensitivity for SN samples was 98.2% (95%CI 90.4-100.0) and for MS 96.4% (95%CI 87.7-99.6) and drops after day 8 below 90%. Discussion: The study is limited to sensitivity of self-collection in symptomatic patients. Still, in this group, self-collected oral/nasal/saliva samples are reliable alternatives to professional-collected cOP/NP samples, if symptom duration does not exceed eight days and operational errors are minimized. Self-sampling could contribute to up-scaling of safe and efficient testing.

Polymorphism of monotropic forms: relationships between thermochemical and structural characteristics

In this work, a database containing thermochemical and structural information about 208 monotropic polymorphic forms has been created and analyzed. Most of the identified compounds (77 cases) have been found to have two polymorphs, 14 compounds have three forms and there are only three examples of systems with four polymorphs. The analysis of density distribution within the database has revealed that only 62 out of 114 metastable polymorphs (referred to as group I) obey the `density rule' proposed by Burger and Ramberger [(1979), Mikrochim. Acta, 72, 259–271], while the remaining 45% of the monotropic systems (group II) violate the rule. A number of physicochemical, structural and molecular descriptors have been used to find and highlight the differences between group I and group II of the polymorphs. Group II is characterized (on average) by higher values of descriptors, which are responsible for conformational flexibility of molecules. An algorithm has been proposed for carrying out bivariate statistical analysis. It implies partitioning the database into structurally related clusters based on Tanimoto similarity coefficients and subsequent analysis of each cluster in terms of the number of hydrogen bonds per molecule.

Towards Sustainability in University Education. Improving University Graduates Chances of Employability by Participation in a High Achievement Academic Program

This piece of research focusses on the sustainable development goal (SDG) number four of the 2030 Agenda for Sustainable Development: quality education. The main objective of this research was to determine whether introducing a High Achievement Academic Program (ARA Groups) at a Spanish public university could enhance its graduates’ employability. According to the existing scientific literature, some variables related to the students’ accomplishments during college are good predictors of future employability: academic performance, participation in international exchanges, and participation in traineeships. In the empirical part of this research, our objective was to compare, using descriptive and bivariate statistical analysis, the behavior of the students of the ARA Groups and the regular ones, regarding a set of variables related to the above-mentioned predictors of employability. The outcomes allow us to conclude that ARA students performed academically better and that they participated more in international exchanges. Participation in business internships did not present significant differences, although ARA students scored higher in the employers’ assessment of the internship. Our results suggest that graduates of this program will be more sought-after by companies, and therefore it contributes positively to one of the key objectives of quality higher education, which is employability, and hence to sustainable development.
