Objectives: Lumbar punctures performed in radiology departments have significantly increased over the last few decades and are typically performed in academic centers by radiology trainees using fluoroscopy guidance. Performing fluoroscopy-guided lumbar punctures (FGLPs) can often constitute a large portion of a trainee’s workday and the impact of performing FGLPs on the trainee’s clinical productivity (i.e. dictating reports on neuroradiology cross-sectional imaging) has not been studied. The purpose of the study was to evaluate the relationship between the number of FGLPs performed and cross-sectional neuroimaging studies dictated by residents during their neuroradiology rotation (NR). Material and Methods: The number of FGLPs and myelograms performed and neuroimaging studies dictated by radiology residents on our neuroradiology service from July 2008 to December 2017 were retrospectively reviewed. The relationship between the number of FGLPs performed and neuroimaging studies (CT and MRI) dictated per day by residents was examined. Results: Radiology residents (n = 84) performed 3437 FGLPs and myelograms and interpreted 33402 cross-sectional studies. Poisson regression demonstrated an exponential decrease in number of studies dictated daily with a rising number of FGLPs performed (P = 0.0001) and the following formula was derived: Number of expected studies dictated per day assuming no FGLPs × e-0.25 x number of FGLPs = adjusted expected studies dictated for the day. Conclusion: We quantified the impact performing FGLPs can have on the number of neuroimaging reports residents dictate on the NR. We described solutions to potentially decrease unnecessary FGLP referrals including establishing departmental guidelines for FGLP referrals and encouraging bedside lumbar punctures attempts before referral. We also emphasized equally distributing the FGLPs among trainees to mitigate procedural burden.

Most previous research has examined the relationship between FB addiction and burnout level by conducting cross-sectional studies. Little is known about the impact of changes in burnout on FB addiction in an educational context. Through a two-way longitudinal survey of a student population sample (N = 115), this study examined the influence of changes in academic burnout over time and FB motives and importance (measured at the beginning and the end of the semester) on FB intrusion measured at the end of the academic semester. The findings show that: (1) increases in cynicism and in FB motives and importance significantly predicted time2 FB intrusion; (2) FB importance enhanced the prediction power of changes in the academic burnout total score, exhaustion and personal inefficacy, and reduced the regression coefficient of changes in cynicism; (3) the interaction effects between FB social motive use and changes in academic burnout, as well as between FB importance and personal inefficacy and exhaustion, accounted for a significant change in the explained variance of time2 FB intrusion. About 20–30% of the variance in time2 FB intrusion was explained by all the examined variables and by the interactions between them. The results suggest that changes in academic burnout and FB motives and importance are suppressive variables, as including these variables in the regression model all together changed the significance of the relationship between independent variables and FB intrusion.

Purpose – Leader-member exchange (LMX) has been proposed as a core mechanism which accounts for the impact of various antecedents on employee outcomes. As such, the purpose of this paper is to examine the mediating effect of LMX regarding the relationship between leader positive humor and employees’ perceptions of organizational cynicism. Design/methodology/approach – Data were collected from 114 public employees. In order to examine the authors’ hypotheses hierarchical regression analysis was conducted. Findings – As hypothesized, results demonstrated that LMX mediates the relationship between leader positive humor and organizational cynicism. Research limitations/implications – Data were drawn from public employees and, therefore, this may constrain the generalizability of the results. Also, the cross-sectional analysis of the data cannot directly assess causality. Originality/value – This is the first empirical study to examine the mediating effect of LMX in the relationship between leader humor and employees’ perceptions of organizational cynicism.

Various risk factors including blood iron may create coronary artery diseases and lead to myocardial infarction. There are controversies with regard to the impact of blood iron on myocardial infarction. Therefore, the aim of this paper was to investigate the relationship between iron reserves and the intensity of coronary artery stenos is among angiographic candidates in Zanjan, Iran. This was a cross sectional study. Samples were consisted of patients who were hospitalized for diagnostic coronary angiography in hospitals in an urban area of Iran. A convenient sampling method was used to recruit samples via interviews and laboratory examinations for FBS, iron, TIBC, ferritin, creatinine serum, CBC, cholesterol, HDL and LDL. The samples were divided into control and intervention groups. After coronary angiography, the intervention group was evaluated by four different methods including the extent score, stenos is score, vessel score and Duke CAN Index. The samples were consisted of 89 men (60.1%) and 59 women (39.9%). The levels of ferritin (p=0.003) and iron (p=0.002), and transferrin saturation percent (p=0.002) showed significant differences between males and females (p=0.004)

Having a board of directors is very important to ensure the smooth running of business processes and have an impact on the company's financial performance. This study to determine the impact of board characteristics namely board size, board ownership and board composition on the financial performance of organizations as measured by Return on Assets. The study employed a descriptive-explanatory research design based on a cross-sectional approach. Correlation and regression analyses were conducted to determine the depth and extent of the relationship between the variables. The study revealed a positive and significant association between the board size and financial performance on an average of 9 board members. Board composition revealed that having more external directors had no effect on the financial performance, it neither increased it nor decreased it, leading to the rejection of the hypothesis. On the other hand, board ownership was found to be beneficial in terms of having directors as owners of the business, corroborating the Stakeholder Theory. The studies showed that there was still a need to select board members with caution striking a balance between the number of directors as well as their composition to ensure that the organization reaps maximum benefits from the board.

The impact of the COVID-19 pandemic on mental health is an emerging problem globally. This study aimed to examine the mediating effect of chronic illnesses in the relationship between psychological health and the acceptance of the COVID-19 vaccine, prior to the national vaccine rollout in Malaysia. An online cross-sectional study was conducted in Malaysia between December 10, 2020, and February 9, 2021. In addition to the descriptive analyses, a mediation analysis was performed to examine the mediating effect of chronic illnesses in the relationship between psychological distress and the willingness to accept the vaccine. A total of 1738 participants completed the survey. The psychological distress levels were found to be significantly different across demographic factors such as age, gender, and social economic status. This study demonstrated a partial mediating effect of chronic illnesses in the relationship between psychological distress and vaccine acceptance.

Numerous studies have investigated the impact of self-esteem and intelligence on academic achievement. The findings are generally inconsistent. The aim of this study was to understand the relationship between intelligence, self-esteem and academic achievement among young people in Kosovo. It was a quantitative cross-sectional study. The sample consisted of 1856 participants, aged 10-18 years old (Mage = 15.29, SD = 1.76). Participants completed the Rosenberg Self-Esteem Scale and The Raven Standard Progressive Matrices. Grade Point Average (GPA) was used to measure academic achievement. Data processing was done with SPSS 21.0 and Microsoft Excel 2013. Participants according to self-reported academic achievement were classified as follows: fail (0.1%), sufficient (2%), good (15.6%), very good (26.7%) and excellent (55.7%). As regards self-esteem participants were classified as follows: low self-esteem (26.9%), and normal self-esteem (73.1%). A significant positive correlation was found between academic achievement and intelligence (r = .31; p = .00) but not between achievement and self-esteem. This significant correlation resulted for both genders separately. The Mann-Whitney test found significant differences in academic achievement between genders and between groups with high intelligence and those with normal intelligence. Intelligence, but not self-esteem revealed a significant relationship with academic achievement. Future studies on the topic might focus on explanatory factors or the possibility of interaction of other variables related to academic achievement.

Purpose This study investigates the relationships among cultural intelligence (CQ), personality and transformational leadership in a student population. The purpose of this paper is to examine the impact of CQ on transformational leadership to see if a relationship exists beyond personality. Design/methodology/approach Hypotheses are presented and tested on a sample of 465 undergraduate and graduate students who attended a large northeastern US university. Hierarchical regression was used to conduct the analysis, and multiple models were generated to test the relationships posited. Findings The data showed that CQ affected transformational leadership; however, when examining the subcomponents of CQ, only behavioral CQ had an impact on transformational leadership beyond personality. Research limitations/implications The surveys were self-reported and cross-sectional, so causality could not be determined. Furthermore, the sample, while diverse, was composed of students. However, scholars will find value in this research because it expands the understanding of CQ. Practical implications The findings of this research indicate that behavioral CQ impacts transformational-leadership skills. Thus, business educators should consider how to build skills associated with behavioral CQ in students because of the importance of global transformational-leadership skills in the workplace. Originality/value This research will impact the literature streams of CQ and transformational leadership because it is the first to examine the relationship between the two while controlling for personality.

Background: Reward sensitivity has been associated with adolescents’ intake of unhealthy snacks and sugar-sweetened beverages. However, so far, there are no studies published describing the impact of parenting practices on this relationship. The present study will, therefore, investigate whether food parenting practices can moderate the association between reward sensitivity and diet intakes. Method: A cross-sectional research study was conducted among 14- to 16-year old Flemish adolescents (n = 867, age 14.7 ± 0.8 y, 48.1% boys) and a subset of their parents (n = 131), collecting data on daily intakes, reward sensitivity, and food parenting practices. Linear regression was used to assess the moderation effect of parenting practices (both adolescent- and parent-reported) on the relationship between reward sensitivity, and diet using SPSS 25.0. Results: In the main analysis (adolescent-reported), no significant moderation effects were found for parenting practices on the relationship between reward sensitivity and diet. However, the sensitivity analysis (parent-reported) showed a moderation effect for health-reducing parenting practices on the association between reward sensitivity and unhealthy snack intake (β = 0.297, 95% CI = 0.062, 0.531, p = 0.01). Conclusion: Given the difference in the effect of parenting practices between the adolescent- and parent-reported data, our inconclusive findings warrant more research in larger adolescent-parent dyad samples.

AbstractAcute gynaecologic disorders are commonly encountered in daily clinical practice of emergency departments (ED) and predominantly occur in reproductive-age women. Since clinical presentation may be nonspecific and physical findings are often inconclusive, imaging is required for a timely and accurate diagnosis. Although ultrasound is the ideal non-invasive first-line technique, nowadays multidetector computed tomography (CT) is extensively used in the ED, particularly when a non-gynaecologic disorder is suspected and differential diagnosis from gastrointestinal and urologic diseases is needed. As a result, CT often provides the first diagnosis of female genital emergencies. If clinical conditions and scanner availability permit, magnetic resonance imaging (MRI) is superior to CT for further characterisation of gynaecologic abnormalities, due to the excellent soft-tissue contrast, intrinsic multiplanar capabilities and lack of ionising radiation.The purpose of this pictorial review is to provide radiologists with a thorough familiarity with gynaecologic emergencies by illustrating their cross-sectional imaging appearances. The present first section will review the CT and MRI findings of corpus luteum and haemorrhagic ovarian cysts, gynaecologic haemoperitoneum (from either ruptured corpus luteum or ectopic pregnancy) and adnexal torsion, with an emphasis on differential diagnosis. Additionally, comprehensive and time-efficient MRI acquisition protocols are provided.
