Postprandial Antioxidative Response to Ingestion of Formulated Date- and Fruit-Based Nutritional Bars by Healthy Individuals.

Nutritional bars (NBs) are gaining popularity among healthy and athletic individuals, but postprandial antioxidative response has not been investigated. Therefore, the current study examined the postprandial alterations in total phenolic content (TPC), total antioxidant capacity (T-AOC), malondialdehyde (MDA), and Superoxide dismutase (SOD) in the plasma of healthy individuals after the ingestion of 140 g (510 Kcal) from formulated date-based bars (DBBs) or fruit-based bars (FBBs). Firstly, the free and bound phenolic contents (PCs) were determined to be 10.15 and 12.98 and 6.19 and 3.57 mg GAE g-1, respectively. FBBs were significantly higher in free PC than DBBs, while DBBs were considerably higher in bound PC than FBBs. Secondly, twenty participants with age, height, weight, body mass index (BMI), fat mass, and fat-free mass averages of 21.4 years, 170.0 cm, 66.3 kg, 22.9 kg m2, 14.5, and 29.2 kg, respectively, were subjected to metabolic experiments (ISRCTN19386758). Ingestion of 140 g of FBB or DBB resulted in 288.50 or 302.14 µg TPC mL-1 blood, respectively. Postprandial TPC content increased with time progression and peaked after 120 min. T-AOC contents averaged 22.63 and 23.61 U mL-1 before ingestion of FBBs or DBBs, respectively. The T-AOC content increased significantly 120 and 180 min after ingestion of DBBs, while no significant change was noted after consuming FBBs. A significant decrease in MDA content was observed 180 min after consuming DBBs, while no significant change was noted after consuming FBBs. SOD concentrations ranged from 193.99 to 201.07 U L-1 in FBBs and DBBs, respectively. No considerable response was noted up to 3 h after ingestion of FBBs. On the contrary, a significant response was found 120 min after consuming DBBs. Pearson's correlation coefficient indicated a highly significant positive correlation coefficient (p < 0.01) between T-AOC and either MDA or SOD, as well as between MDA and SOD. The principal component analysis demonstrated a strong and positive relationship between SOD and TPC at 60 and 120 min after DBB ingestion. In conclusion, the relative changes in postprandial responses in T-AOC and MDA did not significantly (p > 0.05) differ between DBBs and FBBs, except for TPC (p = 0.04, paired t-test) and SOD (p = 0.003, paired t-test). Further studies with an extended experimental time are needed to confirm the current findings.

The mediating role of attention deficit in relationship between insomnia and social cognition tasks among nurses in Saudi Arabia: A cross-sectional study.

Purpose: Insomnia-related affective functional disorder may negatively affect social cognition such as empathy, altruism, and attitude toward providing care. No previous studies have ever investigated the mediating role of attention deficit in the relationship between insomnia and social cognition. Methods: A cross-sectional survey was carried out among 664 nurses (Mage = 33.03 years; SD ± 6.93 years) from December 2020 to September 2021. They completed the Scale of Attitude towards the Patient (SAtP), the Athens Insomnia Scale (AIS), a single-item numeric rating scale assessing the increasing severity of attention complaints, and questions relating to socio-demographic information. The analysis was carried out by examining the mediating role of attention deficit in the relationship between insomnia and social cognition. Results: The prevalence of insomnia symptoms was high (52% insomnia using the AIS). Insomnia was significantly correlated with attention problems (b = 0.18, standard error (SE) = 0.02, p < 0.001). Attention problems were significantly negatively correlated with nurses' attitudes towards patients (b = -0.56, SE = 0.08, p < 0.001), respect for autonomy (b = -0.18, SE = 0.03, p < 0.001), holism (b = -0.14, SE = 0.03, p < 0.001), empathy (b = -0.15, SE = 0.03, p < 0.001), and altruism (b = -0.10, SE = 0.02, p < 0.001). Attention problems indirectly mediated the effect of insomnia on attitudes toward patients (99% CI = -0.10 [-0.16 to -0.05]), respect for autonomy (99% CI = -0.03 [-0.05 to -0.02]), holism (99% CI = -0.02 [-0.04 to -0.01]) empathy (99% CI = -0.03 [-0.04 to -0.01]), and altruism (99% CI = -0.02 [-0.03 to -0.01]). Conclusion: Nurses with insomnia-related attention problems are likely to have poor explicit social cognition such as attitude toward patients, altruism, empathy, respect for autonomy, and holism.

The psychological experience of nursing students in their internship year during the COVID-19 pandemic in Saudi Arabia.

The COVID-19 pandemic produced challenges and troubling issues in Saudi Arabia and worldwide. During the height of the pandemic, the psychological status of nursing students was complicated by challenges that affected their educational future. We used qualitative approach to explore the psychological status of 20 Saudi nursing students from Nursing College in their internship program during the COVID-19 pandemic by investigating their perceptions, experiences, and challenges. Thematic analysis methods were used to present the data as themes and subthemes. Themes that emerged during interviews revealed: Interns' experiences from the outbreak; Perceptions of students toward COVID-19; Mental distress associated with the situation; Level of support from either or both university authorities or hospital education and training departments; Financial challenges; and Readiness to complete a nursing internship. COVID-19 presented several challenges to Saudi nursing students in internship year including psychological distress in several aspects such as fear of infection for themselves and their families. However, this study findings do not apply to all nursing students as it only included nursing interns actively engaged in clinical practice. Additional studies are required to examine how the clinical practice of internships varied across the country during any epidemic situation.

The relationship between nurses' risk assessment and management, fear perception, and mental wellbeing during the COVID-19 pandemic in Saudi Arabia.

During this pandemic, it is crucial to implement early interventions to help nurses manage their mental wellbeing by providing them with information regarding coping skills, preventive risk assessment approaches (such as hospital preparedness and rapid risk assessment), and the ability to respond. This study evaluated the effect of fear and risk assessment management on nurses' mental wellbeing during the COVID-19 pandemic in Saudi Arabia. A total of 507 nurses who worked in tertiary public hospitals were asked to take a descriptive design survey. Three survey scales were used to assess the survey: the Risk Assessment Scale, the Fear of COVID-19 Scale, and the Warwick-Edinburgh Mental Wellbeing Scale. Independent t-tests and a one-way ANOVA were used to examine the association between fear of COVID-19 and nurses' demographic characteristics on their mental wellbeing. A multiple regression analysis was performed to examine the predictors associated with mental wellbeing. Findings revealed that almost half of the participants showed moderate positive mental wellbeing, 49.7%, while only 14% had low levels of fear on the Warwick-Edinburgh Mental Well being Scale. Most of the respondents had low levels of fear on the Fear of COVID-19 Scale, 45%, while only 15% had high levels of fear on the scale. Then, some demographic variables, such as "age," "nationality," "total years of experience in the current hospital," and "region you work at" had statistically significant differences with p < 0.5. Meanwhile, risk assessment is also associated with mental wellbeing scores. All items on the Fear of COVID-19 Scale showed no significant difference with a P > 0.05. In conclusion, most nurses providing direct patient care to a patient with COVID-19 emphasized the importance of wearing PPE and performing hand hygiene before and after any clean or aseptic procedure. Meanwhile, although almost all nurses were vaccinated, they were still afraid of a COVID-19 infection. Additionally, the results reported that the older the nurses are, the better their mental wellbeing scores. Non-Saudi nurses had higher perceived mental wellbeing scores than Saudi nurses, and different working environments corresponded to different mental wellbeing scores. Finally, nurses' risk assessment was associated with mental wellbeing scores.

Interobserver variability in ultrasound assessment of thyroid nodules.

The first diagnostic tool for thyroid disease management is ultrasound. Despite its importance, ultrasound is an extremely subjective procedure that requires a high level of performance skill. Few studies have assessed thyroid ultrasound performance and its effectiveness, particularly the variability between observers in the assessment of ultrasound images. This study evaluated the variability in ultrasound assessments and diagnoses of thyroid nodules between 2 radiologists. In this retrospective study, 75 thyroid nodules in 39 patients were reviewed by 2 experienced radiologists. The nodule composition, margin, shape, calcification, and vasculitis were determined using echogenicity. The study evaluation included these 5 assessments and the final diagnosis. Interobserver variation was determined using Cohen kappa statistics. The interobserver agreements in the interpretation of echogenicity, shape, and margin were fair (κ = 0.21-0.40), whereas there were substantial agreements for vascularity and calcification (κ = 0.62-0.78). The agreements between the observers for individual ultrasound features in this study were the highest for vascularity and the presence/absence of calcification. The interobserver reproducibility for thyroid nodule ultrasound reporting was adequate, but the diagnostic evaluation ability of the observers was inconsistent. The variability in the interpretation of sonographic features could influence the level of suspicion of thyroid malignancy. This study emphasizes the need for consistency in the training of sonographic interpretation of thyroid nodules, particularly for echogenicity, shape, and margin.

Nurses' Perception of Safety Culture in Medical-Surgical Units in Hospitals in Saudi Arabia.

Introduction: Patient safety captures the essence of the primary principle of medical ethics, primum non nocere, first do no harm; this is an important concern in the health care system. Nurses are indispensable members of this system and are the largest group of health care providers involved in the direct delivery of patient care. As an integral part of the health care system, it is important to know nurses' opinions on patient safety culture. Objectives: First, to evaluate and measure the existing safety culture and safety of patients in medical-surgical wards (MSW) in hospitals located in the Qassim region, in the Kingdom of Saudi Arabia. Second, to survey the opinion of registered nurses and supervisors/managers about safety culture and issues concerned with safety in hospitals in the region. Materials and Methods: A validated cross-sectional survey, namely the Hospital Survey on Patient Safety Culture (HSOPSC), was used. This survey queried 300 nurses in different MSWs in four hospitals in the Qassim Region. Results: Overall, a positive culture of safety exists in MSWs, with 69% of RNs rating their wards as having great/excellent safety culture. Notably, some participants felt it was problematic that blame was assigned to nurses for reported errors. While 55.9% of participants noted that all errors or narrowly avoided errors had been reported, less than half actually reported errors in the last year. Conclusion: The perceived safety culture was largely positive; however, the results also indicated that a culture of safety comes with some risk and blame.

Scope of Nursing Practice as Perceived by Nurses Working in Saudi Arabia.

The absence of scope of practice guidelines may lead to role ambiguity and legal consequences in nursing practice. This study measures the scope of practice of nurses in Saudi Arabia. The study utilized a descriptive cross-sectional design using an electronic version of the Arabic Actual Scope of Nursing Practice (A-ASCOP) questionnaire among 928 nurses. Descriptive analysis was followed by a t-test and an analysis of variance (ANOVA). Significance was assured through the Bonferroni test; the effect size was measured through partial η2 when appropriate. The A-ASCOP mean score of each dimension ranged from 4.29 to 4.72 (overall mean = 4.59). Significant overall ASCOP score variations were evident, with higher ASCOP among expatriate nurses, females, Hospital Operation Program (HOP) nurses, and nurses with postgraduate qualifications. Partial η2 showed a small effect of <0.016. Low-complexity nursing tasks showed insignificant differences no matter the nurse's position, but were less practiced by Bachelor of Science in Nursing (BSN) and advanced-degree nurses than by those with a diploma education. High complexity of ASCOP was practiced significantly more often by postgraduate-prepared nurses than by diploma-educated nurses. The study showed that there is a range of variation in nursing practice, but that the lack of internal regulations (nursing scope of practice) has no effect on nursing duties. In a country such as Saudi Arabia, where massive national improvement initiatives are frequent, clearly defining the scope of practice for nurses is essential and needs to be done through government mandates. Further studies are essential to define what the scope of practice should include.

Measuring mental well-being among frontline nurses during the COVID-19 crisis: Evidence from Saudi Arabia.

In the days of the COVID-19 pandemic, frontline nurses providing care to different communities face are particularly vulnerable to the mental health threats of the crisis. The objective of this study was to examine the structural validity, convergent validity, and reliability of the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) in professional nurses amidst the COVID-19 crisis in Saudi Arabia. Data were collected from 413 nurses in Saudi Arabia using a cross-sectional online survey. Consistent with the original version, results of the confirmatory factor analysis revealed a unidimensional structure of the WEMWBS. Support for convergent validity was found as the WEMWBS significantly correlated with measures of burnout and compassion satisfaction. In terms of reliability, all WEMWBS items yielded high internal consistencies suggesting that the 14 items were robust indicators of mental well-being. In response to the challenges of the COVID-19 crisis, the current study offers a psychometrically sound instrument that can be utilized in screening the mental well-being of nurses in the days of a public health crisis. Preserving the positive aspect of mental health among frontline healthcare workers and promoting quality of care for communities requires a contextualized measurement tool that efficiently assesses mental well-being.

Vitamin D and Its Metabolites Deficiency in Acute Coronary Syndrome Patients Undergoing Coronary Angiography: A Case-Control Study.

BACKGROUND: Vitamin D deficiency is considered an emerging health problem that affects at least one billion patients worldwide. Calcitriol 1,25(OH)2D3 has several systemic effects, including anti-inflammatory, anti-thrombotic and anti-atherosclerotic impacts that explain its cardioprotective effects. The precise association between vitamin D and its metabolites and the value of supplements in acute coronary syndrome (ACS) is still controversial. This study aims to search the association between vitamin D2, D3, and metabolites and ACS in patients undergoing coronary angiography. MATERIALS AND METHODS: This was a case-control study on 73 consecutive adult patients with ACS undergoing coronary angiography compared to 50 controls without coronary artery disease and matched for age and sex from June 2019 till July 2019. Echocardiography and coronary angiography were done for all cases. Plasma vitamin D and its metabolites were measured at admission for all participants along with chemistry profiles. RESULTS: Vitamin D and its metabolites were statistically significantly lower in ACS patients than the controls. Multivariate regression analysis revealed that low levels of 25-hydroxyvitamin D (25(OH)D) and 1,25-dihydroxyvitamin D (1,25(OH)2D) significantly predicted ACS occurrence; the other significant predictors were high systolic blood pressure (BP), high total cholesterol, and low high-density lipoprotein-cholesterol. Interestingly, vitamin D2 and D3 did not significantly predict ACS (p>0.05). We did not find a statistically significant association between the number of affected coronary vessels and vitamin D metabolites. Moreover, there was no statistically significant correlation between vitamin D and its metabolites and left ventricular ejection fraction measured by echocardiography. CONCLUSION: There was a strong association between vitamin D and all its metabolites with ACS. Significantly, low 25(OH)D and 1,25(OH)2D predicted ACS, but vitamin D2 and D3 did not. Large randomized controlled trials are needed to verify the beneficial values of vitamin D supplementation in ACS patients.

Awareness, Attitudes, Prevention, and Perceptions of COVID-19 Outbreak among Nurses in Saudi Arabia.

The newly discovered coronavirus (COVID-19) has become a pandemic, infecting thousands of people around the world. This study examines nurses' demographic information (age, gender, marital status, area of practice, total years of experience in the current hospital, work region, monthly salary, educational level, workplace, nationality, working hours per day, total nursing experience, and the respondents' main source of information on COVID-19), awareness, attitudes, prevention, and perceptions of COVID-19 during the outbreak in Saudi Arabia. A cross-sectional descriptive design of 500 nurses working at government and non-governmental hospitals in five regions in Saudi Arabia were selected using convenience sampling. The Kruskal-Wallis test was applied and the Mann-Whitney test was utilized as a post hoc test. The majority of nurses in this study, 96.85%, had excellent knowledge of COVID-19. Some (83.2%) of nurses reported significant prevention knowledge and treatment skills about COVID-19, while 7.6% had little knowledge about prevention. More than half of the nurses (60.4%) had high positive attitudes toward caring for COVID-19 patients. In conclusion, female nurses, married nurses, and bachelor's degree nurses had greater awareness, better attitude, and prevention clinical experience towards COVID-19. Meanwhile, non-Saudi nurses had higher self-reported awareness, positive attitudes, optimal prevention, and positive perceptions compared to Saudi nurses. This study provides baseline information immediately needed to enable health authorities to prioritize training programs that support nurses during the COVID-19 pandemic.

Factors affecting nurses' intention to leave their current jobs in Saudi Arabia.

OBJECTIVE: It is known that job satisfaction and quality of life influence nurses' intention to resign from their jobs. However, health-care systems should examine all the possible factors that contribute to nurse turnover to retain them for the long term. To this purpose, this study further explores the aspects that affect the intention of nurses who work in Saudi Arabia to leave their current jobs. METHODS: A sample of 318 staff nurses working in two public hospitals in Saudi Arabia was surveyed in this cross-sectional study. A questionnaire was used to assess job satisfaction, stress, quality of life, and intention of recruited nurses to leave their current jobs. Data were collected between April and May 2018. RESULTS: Quality of life dimensions, such as physical and psychological health, predict nurses' intention to resign from their current workplaces. We found that being single or of Filipino or Indian origin, working in the medical and surgical department, or having a low monthly gross salary is correlated with a high intention to leave. CONCLUSION: The results present a unique theoretical underpinning that expands on the previous knowledge and literature on the factors that affect nurses' intent to leave their organizations. The findings of this study can be used as a guide to establish human resource policies toward satisfying nurses' needs and improving job satisfaction and quality of life to promote retention.

Migraine screen questionnaire: further psychometric evidence from categorical data methods.

BACKGROUND: Psychometric investigations of tools used in the screening of migraine including the migraine screen questionnaire (MS-Q), using an adequate statistical approach is needed. We assessed the psychometric properties of the migraine screen questionnaire (MS-Q) using categorical data methods. MATERIAL AND METHODS: A total of 343 students at Mizan-Tepi University, Ethiopia, age range = 18-35 years were selected by a simple random sampling method to participate in a cross-sectional study. The respondents completed the MS-Q, a semi-structured socio-demographic questionnaire, and a visual analog scale for attention (VAS-A). RESULTS: The cumulative variance rule (> 40%), the Kaiser's criteria (Eigenvalue> 1), the Scree test and, the parallel analysis (minimum rank) identified a 1-factor model for the MS-Q with the factor loadings in the range of 0.78 to 0.84. Fit indices favored a 1-factor model of the MS-Q as indicated by comparative fit index (0.993), weighted root mean square residual (0.048), root mean square error of approximation (0.067), the goodness of fit index (1.00), and non-normed fit index (0.987). The values of the Factor Determinacy Index (0.953), marginal reliability (0.909), H-latent (0.909), H-observed (0.727), explained common variance (0.906) and the mean item residual absolute loadings (0.225) further complimented finding of the 1-Factor model. McDonald's Omega (0.903) suggested adequate internal consistency. Discriminative validity was supported by significantly higher scores for the total and all the MS-Q items except one among those with complaints of attention. CONCLUSION: The categorical methods support the psychometric validity of the MS-Q in the study population.

Psychometric properties of the Insomnia Severity Index in Ethiopian adults with substance use problems.

This study investigated the psychometric properties of the Insomnia Severity Index (ISI) in substance-using Ethiopian adults. A simple random sampling of houses and a purposive sampling selection was performed in Mizan city, Ethiopia (n = 406). Participants completed the ISI and a meta-cognition questionnaire and sociodemographic information. IBM SPSS software with Amos was used for data analysis. There was no major ceiling or floor effect in the ISI scores. The internal consistency (Cronbach's alpha = 0.68 and 0.78) and internal homogeneity (moderate to strong item-total ISI score correlations; r ≥ 0.47) were adequate. All of the ISI (item as well as total) scores correlated with the meta-cognition total scores (r = 0.16-0.44; p < .01). The exploratory factor analysis results were heterogeneous. However, the confirmatory factor analysis favored a 2-factor model. The ISI has good psychometric validity among Ethiopian adults with substance use.

Exploring nurses' work-related stress in an acute care hospital in KSA.

OBJECTIVES: This study aimed to assess the perceived work-related-stress of staff nurses and determine the relationship between work-related stress and demographic profile. METHODS: This study used a descriptive cross-sectional design and was conducted in a secondary public hospital (staff nurses = 178, bed capacity = 225) in Riyadh, KSA. The hospital provides medical and surgical services that are important to achieve optimum quality patient care and services. In total, 178 staff nurses were interviewed, but 15 responses were excluded because of missing data (response rate: 92.52%). RESULTS: Nurses reported a moderately stressful work environment. Nationality was found to be a significant predictor of nurses' stress levels. Indian nurses had higher stress levels compared with nurses of other nationalities. Working hours per week was another significant predictor of stress. CONCLUSION: This study highlighted perceived work-related stress of staff nurses and determined the relationship between work-related stress and demographic profile. Most nurses were moderately stressed. Working hours were associated directly with stress level. The study findings can serve as a guide for establishing human resources policies aiming at reducing nurses' stress and, thereby, promoting improved health care and task force work performance.

Effectiveness of an early mobility protocol for stroke patients in Intensive Care Unit.

OBJECTIVE: To evaluate the effectiveness of an early mobility protocol for stroke patients in the intensive care unit. METHODS: Participants were patients with first or recurrent stroke (n=60, age=49.02+/- 6.36 years, body mass index=32.95+/-5.67 kg/m2) admitted to the intensive care stroke unit in general hospitals, Riyadh during October and December 2016. Single group pretest-posttest design involving an early mobility protocol was started within first 24 hours admission. Pre and post measurements of muscle strength, pulmonary function and quality of life were carried out. RESULTS: There were significant improvements in muscle strength of upper and lower extremities` muscles after treatment (p less than 0.05), pulmonary functions including Forced Vital Capacity, Forced Expiratory Volume 1 (p less than 0.05) and quality of life, namely, Barthel Index and modified Rankin Scale (p less than 0.01). CONCLUSION: This study demonstrates that initiating an early mobility protocol is safe and effective for intensive care unit stroke patients and supports introducing the current protocol as a standard protocol in neurogenic Intensive Care Units.

Maternity-ward nurses' kangaroo mother care attitudes and practices: implications and future challenges.

BACKGROUND: Successful implementation of KMC depends on the attitudes and practices of maternity-ward nurses. This study assessed the attitudes and practices of kangaroo mother care (KMC) by maternity-ward nurses in the Eastern Philippines. METHODS: A cross-sectional survey design was used in the study. A convenience sample of 138 maternity-ward nurses working in six rural health units (RHUs), two public hospitals and one private hospital. A questionnaire was used to assess the attitudes and practices of KMC by the recruited maternity-ward nurses. Data were collected from June to July 2017 in maternity-ward nurses' workplace. RESULTS: Maternity-ward nurses have a positive attitude towards KMC. Age is associated with attitudes towards KMC. Married maternity-ward nurses have exhibit better attitudes and practice than single nurses. The attitudes of maternity-ward nurses with master's degrees towards KMC are more positive than those with BSN degrees. Maternity-ward nurses from Rural Health Units have better attitudes but fewer support to practice the KMC skills than those from public hospitals. CONCLUSIONS: Maternity-ward nurses who are married, hold master's degrees and are working in RHUs have better KMC attitudes than their counterparts. Maternity-ward nurses have good KMC attitude but poor KMC practices. The KMC information and skills of maternity-ward nurses should be continuously updated to implement KMC effectively and efficiently.

Problem-based learning: medical students' perception toward their educational environment at Al-Imam Mohammad Ibn Saud Islamic University.

BACKGROUND: Problem-based learning (PBL) is a student-centered innovating instructional approach in which students define their learning objectives by using triggers from the problem case or scenario. OBJECTIVES: To assess undergraduate medical students' perception toward PBL sessions and to compare their perceptions among different sex and grade point average (GPA) in the college of medicine, Al-Imam Mohammad Ibn Saud Islamic University (IMSIU), Riyadh, Saudi Arabia. MATERIALS AND METHODS: We conducted a cross-sectional study based on a self-administered anonymous online questionnaire during the first semester of the 2017-2018 academic year in IMSIU. The data were collected from male and female students of the second and third year, as well as male students of the fourth year. RESULTS: Out of 259 students, 152 (58.7%) completed the questionnaire. The students' perception toward PBL was more positive than negative. Most of the students reported that PBL sessions increased their knowledge of basic sciences (P=0.03). Furthermore, most students agreed that PBL provided a better integration between basic and clinical sciences which differed significantly between the different GPA groups (P=0.02). Nevertheless, only 28.3% of the students agreed that the teaching staff is well prepared to run the sessions with significant statistical difference among different GPA groups (P=0.02). Moreover, only 26.3% of the students reported that there was proper student training before starting the PBL sessions with no significant difference. Additionally, only 34.2% and 28.9% of the students felt that they learn better and gain more knowledge thorough PBL than lectures respectively, with no significant difference. CONCLUSION: This study showed that tutors should be trained to guide the process of PBL effectively to achieve its goals. Moreover, students should be securely introduced to PBL and experience the development of their clinical reasoning through PBL. Further improvements are needed to provide students with an effective favorable learning environment and to take the students recommendations into consideration.

Psychometric properties of the Epworth sleepiness scale in Ethiopian university students.

BACKGROUND: Daytime sleepiness is highly prevalent across the globe. The Epworth sleepiness scale (ESS) is the most widely used tool for screening daytime sleepiness. The psychometric properties of the ESS have not been comprehensively examined in African populations. MATERIAL AND METHODS: A cross-sectional design with simple random sampling was used in the present study. The study recruited 600 students from Mizan-Tepi University, Ethiopia, of which 329 (age = 18-28 years and body mass index = 21.19 ± 3.17 kg/m2) completed the study. ESS, a semi-structured socio-demographics questionnaire and a clinical interview to diagnose insomnia according to the International Classification of Sleep Disorders were employed. RESULTS: All except one item of the ESS showed a floor effect, while only one item score showed ceiling effect. However, no ceiling/floor effect was observed in the ESS total score. The Cronbach's alpha (0.75) and composite reliability (0.75), indicated good internal consistency, while a moderate item-total score correlation (r = 0.55-0.67) implied favorable internal homogeneity. The known-group validity was established by significantly higher scores for all the ESS item scores and the ESS total scores among those with symptoms of insomnia than among non-symptomatic students. Fit indices along with the consideration of inter-factor correlation coefficient, measures of item retention favored the unidimensional structure of the ESS. CONCLUSION: The ESS has excellent psychometric validity for screening daytime sleepiness in Ethiopian university students.

The Arabic version of the Kogan Attitudes toward Older People Scale among Saudi nursing students: a psychometric analysis.

BACKGROUND: With the steadily increasing size of its elderly popu.lation, Saudi Arabia is currently trying to meet the demands for com.petent care for older people. However, the lack of a valid and reliable measurement instrument in the Arab Peninsula hinders related studies among nursing students in this part of the globe. Given the importance of nursing students' attitudes toward working with older people, a specialized tool that can provide an accurate assessment of students' attitudes toward older adults is necessary. OBJECTIVE: Evaluate the psychometric properties of the Kogan Attitudes towards Older People Arabic version (KAOP-A) among Saudi nursing students. DESIGN: Descriptive, cross-sectional. SETTING: Nursing department of a government university. SUBJECTS AND METHODS: Using total population sampling, Saudi nursing students were surveyed using the KAOP-A. The tool was culturally adapted to the Arabic language using a forward and backward method. Content and construct validity were established accordingly. The internal consistency was established to support the reliability of the tool. MAIN OUTCOME MEASURES: The validity and reliability of the KAOP-A. SAMPLE SIZE: 164 nursing students. RESULTS: The KAOP-A had acceptable content and construct valid.ity. The Exploratory Factor Analysis supported a two-factor solution for the KAOP-A with an explained variance of 60.12%. The computed Cronbach's alpha for the entire scale was 0.89. The mean score of the KAOP-A scale was 121.55 (SD=26.92, range=40-204), indicating a slightly positive attitude toward aging among the students. Nursing students belonging to extended type of family and living in rural community, as well as older students and students who reported higher degree of closeness with their grandparents, exhibited more positive attitudes towards older people. CONCLUSION: The tool can be used to accurately assess student attitudes towards older people, which can inform the creation of educational policies and interventions geared towards creating a more positive outlook on older adult care among nursing students in Saudi Arabia. LIMITATIONS: We did not perform test and re-test reliability analysis. CONFLICT OF INTEREST: None.

Poor sleep in concurrent users of alcohol, khat, and tobacco smoking in community-dwelling Ethiopian adults.

BACKGROUND: Polysubstance dependence, stress, and sleep disturbances are inter-related by shared physiological pathways. No study has investigated the relationship between sleep and concurrent use of alcohol and khat. OBJECTIVES: The aim of the study was to assess the effect of the concurrent use of alcohol and khat as well as concurrent alcohol, khat, and tobacco smoking on sleep patterns. METHODS: A sample of community-dwelling adults (n = 339, age = 25.5 ± 5.7 years, body mass index = 22.0 ± 2.2 kg/m2) from Mizan-Aman, Ethiopia, participated in a cross-sectional study. Semi-structured tool for sociodemographics, substance use habit, and the Pittsburgh Sleep Quality Index (PSQI) were used. The difference in sleep patterns among substance use groups, i.e., nonusers, alcohol use only, concurrent alcohol and khat use, and concurrent alcohol, khat and tobacco smoking was assessed. RESULTS: The poorest sleep quality was found among concurrent users of alcohol, khat, and tobacco smoking (PSQI global score = 8.2 ± 2.4), followed by concurrent users of alcohol and khat (PSQI global score = 7.3 ± 2.9) (F (3.335) = 23.64, P < 0.001). There were significant differences in the PSQI component score of sleep quality χ 2(3) =159.09, P < 0.001, the PSQI component score of sleep latency χ 2(3) = 128.09, P < 0.001, and the PSQI component score of sleep disturbances χ 2(3) = 37.69, P < 0.001 between substance use groups. CONCLUSION: Concurrent use of alcohol, khat as well as alcohol, khat, and tobacco smoking was associated with poor sleep. Sleep disturbances in this group need management to avoid the prospective development of psychosocial disturbances in polysubstance users.
