Abstract Background Smartphone plays a vital role in higher education as it serves as a device with multiple functions. Smartphone addiction was reported on the rise among college and university students. The addiction may result in unwanted consequences on their academic performance and psychological health. One factor that consistently relates to psychological distress and smartphone addiction is the neurotic personality trait. This study explored the relationship of smartphone addiction with psychological health and neuroticism among USM medical students. Methods A cross-sectional study was carried out on medical students in a public medical school. DASS-21, the neuroticism-subscale of USMaP-i and SAS-SV were administered to measure psychological distress, neuroticism, and smartphone addiction of the medical students. Spearman correlation was performed to examine the correlation between smartphone addiction with psychological distress and neuroticism. Simple linear regression was performed to investigate relationship factors of smartphone addiction. Results A total of 574 medical students participated in this study. The prevalence of smartphone addiction was 40.6%. It was higher among male (49.2%) compared to female (36.6%) medical students. The result showed a fair positive correlation between smartphone addiction and psychological health (rdepression = 0.277, p-value < 0.001; ranxiety = 0.312, p-value < 0.001; rstress = 0.329, p-value < 0.001). However, there was a poor positive correlation between smartphone addiction and neuroticism (r = 0.173, p-value < 0.001). The simple linear regression showed a significant increase in the levels of depression, anxiety, stress and neuroticism upon one unit increase in smartphone addiction (bdepression = 0.101, p-value < 0.001; banxiety = 0.120, p-value < 0.001; bstress = 0.132, p-value < 0.001; bneuroticism = 0.404, p-value < 0.05). These results indicated significant relationships between smartphone addiction, psychological health and neuroticism. Conclusion This study suggested a high prevalence of smartphone addiction among medical students, particularly in male medical students. The smartphone addiction might lead to psychological problems and the most vulnerable group is the medical student with the neurotic personality trait.

Abstract Abstract 3487 Hematopoietic stem cell transplantation (HSCT) is associated with poor response to platelet (PLT) transfusions. It has been posited that vascular endothelial cell (EC) damage from the effects of high dose chemoradiotherapy is responsible for PLT consumption. To test this hypothesis, we assessed the relationship between serial levels of plasma markers of vascular damage and repair, and PLT transfusion requirement. Plasma samples were obtained on 40 adult and pediatric recipients of allogeneic HSCT with myeolablative conditioning for leukemia, lymphoma, or myelodysplastic syndrome at days -10, +5, +15, and +30. Single donor apheresis PLT transfusions were given prophylactically for PLT count <10,000/mcL or as needed for hemorrhage. To minimize the influence of the rate of engraftment only transfusions through day +15 were considered. The number of transfused PLT units divided by patient's body weight (BW) was recorded. For patients with BW >125% of ideal BW, adjusted BW was calculated as 0.25 × (actual – ideal BW) + ideal BW. The influence of response to PLT transfusions prior to transplant admission was considered. Poor response to PLT transfusion was defined as a PLT count rise of <30,000/mcL on the last PLT transfusion prior to HSCT; individuals with poor response to PLT transfusions prior to HSCT were not excluded. Plasma levels of angiopoietin-2 (Ang-2), platelet-derived growth factor-BB (PDGF-BB), soluble Platelet Endothelial Cell Adhesion Molecule (sPECAM), and vascular endothelial growth factor (VEGF) at each time point were measured using a multiplex ELISA, and the ratio of each biomarker level at days +5 +15, and +30 to the baseline level (day -10 pre-HSCT) was calculated. The ratios of the biomarker level at each time point to baseline were compared by 1-way ANOVA. The relationship of cumulative PLT transfusions at day +15 to the logarithm of each biomarker ratio was assessed by Pearson's correlation coefficient. Simple linear regression was used to assess the relationships of age, gender, total body irradiation (TBI), donor matching, stem cell source, hemorrhage, hepatic veno-occlusive disease (VOD), and prior response to PLTs with cumulative PLT transfusions, and significant variables were introduced into multivariable analysis to assess the relationship of significant biomarker ratios to PLT transfusions. Four patients were excluded from analysis, 1 for death at day +13 and 3 for insufficient samples. The median age was 17.0 years (range 6.7–55.4 years). Nine patients received HLA matched related donor transplants and 31 received alternative donor transplants. TBI was used as part of conditioning in 20 patients, VOD developed in 5, and hemorrhage occurred in 13. The mean number of platelet transfusions from days -10 – 15 was 1.1 units/10 kg BW (range 0.12–3.7 units/10 kg). Ten patients had poor responses to PLT prior to HSCT, 21 had good responses to PLT, and 5 had insufficient data regarding PLT response. Significant reductions were observed in sPECAM-1 at day 5 (mean ratio 0.58 of baseline, range 0.29–1.05, p<0.0001) and in PDGF-BB (mean ratio 0.59 of baseline, range 0.03–2.44, p=0.0198). VEGF was mildly increased over baseline at day 5 (mean ratio 1.49 of baseline, range 0.29–8.4, p=0.048). Ang-2 level was increased over baseline at days 5 and 15, peaking at 8.8-times greater than baseline on day 15 (p=0.075). The log of (Ang-2 day 15/Ang-2 baseline) had a significant positive correlation with cumulative PLT transfusions at day 15 (r2=0.32, p=0.05) (Figure). In simple linear regression, PLT transfusion at day 15 also was associated with hemorrhage (p=0.008) and VOD (p=0.083). Poor PLT response prior to HSCT was not associated with cumulative PLT transfusions at day 15 (p=0.47). In multiple linear regression controlling for hemorrhage and VOD, the association of log(Ang-2 day 15/Ang-2 baseline) with cumulative PLT transfusions remained significant (p=0.024). In conclusion, significant decreases in plasma levels of the vascular adhesion molecule sPECAM-1 and angiogenic growth factor PDGF-BB are seen at day +5 in HSCT. There was wide variation in Ang-2 levels; however increased Ang-2 at day +15 was associated with increased cumulative PLT transfusions at day +15, suggesting that vascular regeneration is associated with increased PLT consumption.

To investigate the epidemiological relationship of dietary factors to blood pressure (BP) and major cardiovascular diseases, we carried out the international cooperative Cardiovascular Diseases and Alimentary Comparison (CARDIAC) Study, which so far involves 48 centers in 20 countries as of August 1991. From each population, 100 men and 100 women aged 50–54 years were randomly selected for BP measurement, 24-h urine collection, blood tests, and medical interview. Various biological markers of diets from urine and blood were analyzed centrally in the Izumo CARDIAC center. Cross center analysis using simple linear regression revealed strong significant correlations of body mass index (BMI) to systolic BP (SBP; p 0.01) and diastolic BP(DBP; p 0.001) in men. 24-h urinary sodium (Na) excretion in men also showed significant correlations with SBP (p 0.05) and DBP p 0.05) even after controling for the effect of BMI (SBP; p 0.05, DBP; p 0.05). Within center analysis using multiple linear regression implied that BMI and Na strongly adversely affect BP, whereas magnesium may have beneficial influence on BP. Multicolinearities among 24h urinary sodium, calcium, and urea nitrogen were noted in men.

Introduction:  Smartphones has now become a common and almost essential tool in our daily living activities. Students are among those who uses smartphones regularly which could lead to addiction if overused. This study aims to measure the prevalence of smartphone addiction and its relationship with psychological health among clinical year medical students in International Islamic University Malaysia (IIUM), Kuantan. Materials and method: A total of 203 Medical students in their clinical years were recruited via quota sampling method. The students filled in a four part online-based questionnaire consisted of questions on sociodemographic characteristics, smartphone usage information, Smartphone addiction scale-short version (SAS-SV) and WHOQOL-BREF. Data was analysed using IBM SPSS Statistics. Result: The prevalence of smartphone addiction among clinical year Medical students in IIUM was 51%. Bivariate analysis showed that majority of students chose social networking as their primary purpose of smartphone usage and this is significantly associated with smartphone addiction (p-value:0.037). Following multiple logistic regression analysis, students who had chosen games as their primary purpose of smartphone usage are 88% less likely to be related with smartphone addiction (p-value: 0.009, 95% CI: 0.025-0.595) compared to those who used it for academic performance tasks. Students who are not addicted to smartphones reported significantly better psychological quality of life compared to those who are addicted  (p-value<0.001). Conclusion:  Half of IIUM’s Medical students in clinical years have smartphone addiction and those with smartphone addiction was found to have poor psychological health. Immediate intervention such as creating awareness in the campus is important in curbing this problem.

The question of compensation in addition to sensitive to be driving someone to worl due to an effect on morale and discipline employees. Therefore , any  agency or any organization should be able to provide compensation equal to the workload  to create a workforce that efficient and effective manner can be realized. Amaore than that, the company’s goal to improve performance. Performance assessment is a subjective process that involves human judgments. Thus, performance assessment is very likely wrong and very easily influonced by sources that are not actual, so it must be taken into account and considered reasinable. Frformance appraisals are considered  to meet the target if it has a good impact on new employees who rated their performance. Simple linear regression analysis using SPSS version 12:00 data processing obtained tegression equation Y = 0,487 X 74 + with an explanation of X = award, 74 = constant, 0.487 = coefficient awards, and Y = performance based on simple linear regression equation in case of increase of one unit of the  performance award will be increased 0.487 units. If company policy negates the performance award will remain at a constant rate (74) units .
