Health-Related Quality of Life in Patients with Systemic Lupus Erythematosus and Rheumatoid Arthritis Compared to the Healthy Population in Shiraz, Iran

Background: Systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) are chronic and complex autoimmune diseases, involvingmultipleorgans. Therefore,qualityof life(QoL)inSLEandRApatientscanbeaﬀected. Thecurrentstudyaimedtocompare SLE and RA patients with the healthy population in terms of health-related QoL (HRQoL) in Shiraz, Iran. Methods: Thepresentcrosssectional,analyticalstudywasperformedon100SLEpatients,100RApatients,and200healthycontrols, who were referred to the rheumatology clinics (Motahari and Hafez clinics) of Shiraz University of Medical Sciences. Demographic dataincludingage, gender, educationallevel, anddiseasedurationwereevaluated. ThePersian-translatedversionof 36-itemshort-form health survey (SF-36) was used as a tool for evaluating HRQoL. For statistical analysis, Pearson’s correlation test, t-test, and ANOVA were performed, using SPSS. Results: Comparison of SLE and RA patients with healthy controls showed that the control group obtained higher scores in 8 sub-scalesof SF-36questionnaire. Basedontheﬁndings,RApatientshadthelowestscoresbetweenthegroups. Ageanddiseaseduration had a signiﬁcant negative linear correlation with HRQoL, while educational level had a signiﬁcant positive linear correlation with HRQoL. Nevertheless, there was no signiﬁcant correlation between gender and HRQoL. Conclusions: HRQoL was lower in RA patients in comparison with the SLE group. In fact, RA patients, who suﬀered from body pain anddisability,obtainedlowerscoresinbothphysicalandmentaldomains. Therefore,promotingthepatients’ healthliteracy,asan empowerment strategy, plays a key role in improving HRQoL.
Optical coherence tomography in ischemic optic neuropathy

Ischemic optic neuropathies are among the most common causes of sudden vision loss, especially in patients over age 50. The cause and prognosis of these disorders, and in particular non-arteritic anterior ischemic optic neuropathy, is poorly understood, and treatments remain poor in terms of restoring or preserving vision. Optical coherence tomography (OCT) and OCT angiography have allowed us to identify early and late structural changes in the optic nerve head and retina that may assist in predicting visual outcomes and may lead to greater understanding of pathogenesis and thus the development of effective medical interventions.

User Education and Computer Literacy Skills as Determinants of Electronic Resources Use Among Undergraduate Students in State Universities in South-West, Nigeria

This study investigated the user education and computer literacy skills as determinants of electronic resources use among undergraduates in South-west, Nigeria. The descriptive survey research design was employed for this study. The results indicated that; nearly all the electronic resources were grossly not available and only few were available when the need arise; students had low frequency of usage as regard electronic library resources; there is a positive non-significant relationship between user education and the use of electronic resources among undergraduate students of state university in South-west Nigeria; there is a positive significant relationship between computer literacy and the use of electronic resources among undergraduate students of state university in South-west, Nigeria. It was recommended that; there should be an expansion of all existing computer departments in the universities to enable them produce more of computer literacy, libraries should employ professionally trained and competent librarians who should be sent periodically to seminar and workshops to update their knowledge and the library should strive to equip their students with sufficient practical skill to make them self-reliant in the global market of unemployment.
Correlation between Exam Completion Sequence and Resulting Scores in a Construction Management Program

This paper reports the results of a study that explored whether the completion order of multiple-choice exams were correlated to their respective average scores. This study addressed an important aspect of college education. Exams are crucial tools for the assessment of a student’s academic performance, and even small variations in their administration can have significant consequences for a student. From a student’s perspective, exams are stressful events that not only determine a course grade, but also can make the difference for getting accepted to a college program or having a good resume for a job recruiter. From an instructor’s viewpoint, exams are almost always the main instrument for gauging a student’s mastery of a course contents, and therefore, for assigning an equitable grade to the student’s performance. Exams are imperfect instruments to measure many of the skills relevant to a student’s professional life (Stenberg, 2004, Foster, 2008). Despite their limitations, exams are likely to remain serving as the main means to measure a student’s mastery of a course material, and therefore, every effort to understand their structure and administration is important.
Epidemiology of Periodontal Disease among the Elderly

The present study aims to reflect on the oral health status of the elderly, addressing periodontal disease, as well as the importance of oral health, general health and quality of life. The methodology adopted consisted of a bibliographic research of scientific articles indexed in PUBMED® and Google Scholar® with the following combined keywords: “Periodontal Disease”, “Gerodontology”, “Oral Health”, “Elderly” and “Epidemiology”, either in Portuguese or in English. The exclusion criteria for the selection of the scientific articles used consisted in limiting the research to the Portuguese and English languages, limiting the publication date to the last 10 years, and only scientific articles referring to the epidemiology of periodontal disease among the elderly. Therefore, from a total of 33 scientific articles, only 17 scientific articles were selected for the present research. The most recent studies do show that periodontal disease is clearly a public health issue, increasing among all ages. However, this oral pathology should be carefully analyzed among the elderly considering the higher risk of association with the development of other systemic diseases and also the physiological, mental and social changes that characterize this specific age group.

Investigating the relationship between emotional displays of nursing managers and the performance of nursing staff (Case study: Dr. Shariati Hospital, Tehran)

Emotional display is the management and proper expression of correct emotions consistent with organizational and profession rules. One of the factors affecting the occupational performance is the skills of the managers in control and effective use of excitement. The present study was conducted to determine the relationship between nursing managers' emotional display and the performance of nursing staff. The study population consisted of all managers and nursing staff of Shariati Hospital, Tehran in 2015 who were selected using census method. The instruments were Dindorf et al. emotional display questionnaire and Paterson's job performance questionnaire whose validity and reliability were confirmed. Data were analyzed with Spearman correlation Coefficient, independent t-test, and ANOVA using SPSS software. "Real-emotion display" of nursing managers had a significant correlation with nursing staff performance (P=0.02, r=0.203). But "superficial and deep display of emotions" of the managers did not. There were no significant correlations between emotional display with age and work experience in managers and between job performance with marital status, gender, and age and work experience in nursing staff (P>0.05). The results showed that design and implementation of training courses about emotional display are necessary in managers in order to improve the job performance of nursing staff.

Does the 2019 Coronavirus Exist?1

The Coronavirus scare that emanated from Wuhan, China in December of 2019 is an epidemic of testing. There is no proof that a virus is being detected by the test and there is absolutely no concern about whether there are a significant number of false positives on the test. What is being published in medical journals is not science, every paper has the goal of enhancing the panic by interpreting the data only in ways that benefit the viral theory, even when the data is confusing or contradictory. In other words, the medical papers are propaganda.
Predictors of poor bowel preparations and colonoscopy cancellations in inpatient colonoscopies, a single center retrospective study.

Background An adequate bowel preparation prior to colonoscopy is a major quality-limiting factor that determines both the diagnostic and therapeutic yield of a colonoscopy. Colonoscopy is considered the gold standard for colon cancer screening and it is the primary approach to the workup of hematochezia, diarrhea and iron deficiency anemia (IDA). Several modifiable factors of bowel prep adequacy have been identified, that account for around 25% of inadequate bowel preparations in outpatient colonoscopies. However, the literature is sparse when examining the factors associated with inadequate preparations and procedure cancellations in an inpatient hospital setting. We aim to identify factors that affect bowel preparation adequacy and procedure cancellations among diagnostic colonoscopies performed during hospitalization. Methods We retrospectively reviewed the electronic medical records of 1,500 consecutive patients who had a diagnostic colonoscopy as an inpatient at a tertiary level hospital over a 2-year period. All patients were administered a clear liquid diet the day prior to the colonoscopy. Patients were then instructed to drink 4 L of polyethylene glycol (PEG, Golytely) between 5 am to 9 am on the day of the procedure. The clinical course of each case was followed to identify quality of preparations, cancelled procedures and the reasons for cancellations. We applied univariate and multivariate logistic regression analysis to identify variables to predict cancellation and poor preparation. Results A total of 1,029 patients were included in the study. 194 (18.8%) patients had colonoscopy cancellations and 268 (26.0%) had poor bowel preparations. Multivariate analysis revealed these factors to be associated with colonoscopy cancellations: education at the graduate school level [odds ratio (OR) =1.93, P=0.04], Hispanic ethnicity (OR =0.47, P<0.01), hemoglobin level <10 g/dL (OR =1.41, P=0.05) and if the colonoscopy was done for other indications (OR =0.53, P=0.04). Factors associated with poor bowel preparation on multivariate analysis, were dementia (OR =2.44, P=0.02), gastroparesis (OR =3.97, P=0.01) and inpatient opioids use (OR =1.69, P=0.04). Conclusions The rate of colonoscopy cancellations and poor bowel preparations in inpatient colonoscopies were high, and we were able to identify predictors of inadequate colon preparation and procedure cancellations. Exploring more individualized colon preparation regimens based on personal risk factors could reduce the number of inadequate and cancelled colonoscopies in an inpatient setting.
The burden of HIV/AIDS among slum-dwelling school-age children in Kampala, Uganda

Introduction: Adult and youthful slum dwellers have been documented to have a higher prevalence of human immunodeficiency virus (HIV) compared to the general population. However, there is paucity of information on the extent of this infection among slum-dwelling school-age (5-14 years) children in Uganda. This study explored the burden of HIV among slum-dwelling school-age children (SDSAC) of Namuwongo, Kampala, Uganda. Material and methods: We analysed data derived from HIV counselling and testing records of schoolage children that tested at Kisugu HCIII between 2011 and 2016. A total of 555 anonymised records were analysed for: residence, HIV, religious, and sex status. Using STATA version 13, bi-variate analysis was conducted to obtain joint distribution, and the two-sample test of proportions test was used to elicit associations and their significance. Results: The overall study population burden of HIV was 2%, with girls (2.6%) more affected than boys (0.9%). SDSAC had a higher HIV burden (3.3%) compared to non-slum dwellers (1.2%). HIV was more prevalent among slum-dwelling girls (5.2%) compared to their non-slum dwelling counterparts (0.9%). A positive HIV result was associated with being a slum dwelling girl (95% CI: [0.3-8.3], p = 0.013) and belonging to the 10-14-year age group (95% CI: [0.002-0.065], p = 0.015). Conclusions: There is a high burden of HIV among slum-dwelling school-age girls in Kampala. SDSAC should be included among the blind spot population, and we recommend expansion of school-age-friendly, preventive, promotive, and therapeutic HIV services to these areas.

The Role of Syntactic Awareness and Metacognitive Awareness Reading Strategies in Reading Comprehension of EFL Learners (DMU English Majoring Students in Focus)

This paper explores whether syntactic awareness or metacognitive awareness reading strategies is strong predictors of reading comprehension. It also addresses the relationship among syntactic awareness, metacognitive awareness reading strategies and reading comprehension achievement. To attain this objective, descriptive research using a correlational research design was employed. 30 participants were selected from a population of 50 2 nd year English majoring students using simple random sampling. The participants were asked to respond to a MARSQ developed by Taraban, Kerr and Ryneason (2004) and researcher-made tests of syntactic awareness and reading comprehension. Pearson product moment correlation and stepwise multiple regression analysis were used in data analysis. The results of the correlation analysis showed that among the variables namely, EFL learners' syntactic awareness and metacognitive awareness reading strategies, high correlation holds for the relationship between syntactic awareness and reading comprehension, but there were no significant correlation with metacognitive awareness reading strategies. The stepwise multiple regression analysis results also revealed that EFL students' syntactic awareness plays a significant role in predicting their reading comprehension achievement compared to metacognitive awareness reading strategies. Finally, some useful implications and recommendations which are of significance to educators, teachers and researchers are proposed based on the research findings. Accordingly, the result contends that instructions on developing reading comprehension should put syntactic awareness competencies in priority and then focus on activation of background knowledge and use of reading strategies for the success of reading comprehension.
Hysteroscopy Vs. transvaginal ultraultrasonography in the diagnosis of endometrial lesions

Background: Abnormal uterine bleeding (AUB) is the most common gynecological problems that many factors are involved in its creation. Two common methods used to diagnose uterine lesions are vaginal ultraultrasonography and hysteroscopy. The aim of this study was to evaluate the diagnostic value of transvaginal ultraultrasonography and hysteroscopy in the diagnosis of intrauterine lesions leading to the AUB. Methods: A cross-sectional study was performed on 203 premenopausal post-menopausal women with complaints of abnormal uterine bleeding. A transvaginal ultraultrasonography was performed from the eligible subjects. In the second visit, a hysteroscopy was done and during the hysteroscopy procedure an endometrial biopsy was obtained from all the women. Pathology was considered as the gold standard and sensitivity, specificity, positive predictive value and negative predictive value were calculated for both methods using the Cat maker software. Results: The mean age of 203 patients who precipitated in this study was 43.1±2.7. Leiomyoma was the most common leading cause of abnormal uterine bleeding (36%). Sensitivity, specificity, positive predictive value and negative predictive value of ultraultrasonography in the diagnosis of intrauterine lesions were 74.2%, 49.75%, 71.9% 54.3%, respectively and for hysteroscopy were 91.67%, 86%, 85.9% and 88.7, respectively. Conclusion: Hysteroscopy results were more consistent with the results of pathology and it was more accurate than transvaginal ultraultrasonography in the diagnosis of intrauterine lesions leading to the AUB.
The Effect of Conjugal Bereavement on Health and Mortality at Older Ages

This study assesses the effects of spousal bereavement on health and mortality risks at advanced ages. We specify a model for the life times of couples and the dynamics in health and estimate it on a rich longitudinal survey. The survey is linked to administrative records on the vital status of the main respondent and his/her partner. We find strong direct effects of bereavement on mortality and on some aspects of health. Individuals lose on average 12 % of residual life expectancy after bereavement. Bereavement affects the share of healthy years in residual lifetime, primarily because healthy years are replaced by years of having chronic diseases.
Convolutional Neural Networks accurately predict cover fractions of plant species and communities in Unmanned Aerial Vehicle imagery

Unmanned Aerial Vehicles (UAV) greatly extended our possibilities to acquire high resolution remote sensing data for assessing the spatial distribution of species composition and vegetation characteristics. Yet, current pixel‐ or texture‐based mapping approaches do not fully exploit the information content provided by the high spatial resolution. Here, to fully harness this spatial detail, we apply deep learning techniques, that is, Convolutional Neural Networks (CNNs), on regular tiles of UAV‐orthoimagery (here 2–5 m) to identify the cover of target plant species and plant communities. The approach was tested with UAV‐based orthomosaics and photogrammetric 3D information in three case studies, that is, (1) mapping tree species cover in primary forests, (2) mapping plant invasions by woody species into forests and open land and (3) mapping vegetation succession in a glacier foreland. All three case studies resulted in high predictive accuracies. The accuracy increased with increasing tile size (2–5 m) reflecting the increased spatial context captured by a tile. The inclusion of 3D information derived from the photogrammetric workflow did not significantly improve the models. We conclude that CNN are powerful in harnessing high resolution data acquired from UAV to map vegetation patterns. The study was based on low cost red, green, blue (RGB) sensors making the method accessible to a wide range of users. Combining UAV and CNN will provide tremendous opportunities for ecological applications.
An Experimental Study on the Abortificient Potentials of Unripe Seed Extract of Carica papaya in Adult Female Wistar Rats

This study is aimed at investigating the abortifacient potentials of Caricapapaya (C. papaya) using adult female rats as a model. Female rats (CP1 – CP5) served as the experimental group while female rats (CP6 and CP7) served as the control group. Each rat in both groups was given 20g of normal rat chow and water adlibitum during the experiment. In addition to this diet, each rat in the experimental group was force fed orally with 1ml/kg body weight of aqueous seed extract of unripe C. papaya form by dissolving 1gram of blended fresh C. papaya seed in 10ml for 2hrs. Administration of aqueous seed extract of C. papaya begins from the 5th day to 15th day. The results showed that mean body weights were significantly lower (p<0.05) in the group treated with extract of C. papaya at the second (233.00±20.00g versus 194.00±22.21g) and third week (272.40±45.50g versus 185.00±21.25g) of pregnancy compared to the control. Our findings indicate that C. papaya seed is abortifacient. It also showed that the time window of pregnancy at which the seed extract of C. papaya exhibited abortifacient effect was from the second trimester of pregnancy and resulted into zero fetus at the end of the third trimester.
