Employees’ commitment seems to be vital in decision making for any organizations in order to be able in business competition and to adapt with changes. The commitment among employees can be a crucial tool for improving their performance in organizations. Communication is needed to raise awareness among employees on the need of change as well as creating the readiness to the change whereby it leads to the commitment to change. The objective of this paper is to examine the influence of internal communication on employees’ commitment to change. Apparently, this issue likely has attracted the attention among either scholars or researchers. The theoretical contribution has been added in this study by investigating the effect of internal communication in influencing employees’ commitment to change. A survey of structured questionnaire was conducted in five-hundred fifty employees in Malaysian large companies. The significant relationship has been found between internal communication and employees’ commitment to change through multivariate regression analysis. Moreover, the implications to practice and theory are discussed.

Objective Previous reports have indicated that serum bilirubin levels may be associated with diabetic retinopathy. However, the detailed mechanism is not fully understood. In this study, we evaluated the relationship between the severity of diabetic retinopathy and various factors including bilirubin levels and factors influencing bilirubin metabolism. Methods The study participants consisted of 94 consecutive patients with diabetes mellitus admitted to Kyushu University Hospital from April 2011 to July 2012. The patients were classified into three groups: no retinopathy (NDR), simple retinopathy (SDR), and pre-proliferative or proliferative retinopathy (PDR). The relationship between the severity of retinopathy and various factors was evaluated using univariate and logistic regression analyses. In addition, multivariate regression analysis was performed to evaluate the significant determinants for bilirubin levels. Results In univariate analysis, a significant difference was found among NDR, SDR and PDR in bilirubin levels, duration of diabetes, systolic blood pressure, and macroalbuminuria. Logistic regression analysis showed that PDR was significantly associated with bilirubin levels, duration of diabetes, and systolic blood pressure (OR 0.737, 95% CI 0.570–0.952, P = 0.012; OR 1.085, 95% CI 1.024–1.149, P = 0.006; OR 1.036, 95% CI 1.011–1.062, P = 0.005, respectively). In turn, multivariate regression analysis showed that bilirubin levels were negatively associated with high-sensitivity C-reactive protein levels and PDR, but positively correlated with urinary biopyrrin levels, oxidized metabolites of bilirubin. Conclusion PDR was negatively associated with bilirubin levels. This negative association may be due to a decreased production of bilirubin rather than its increased consumption considering the positive association between bilirubin and biopyrrin levels.

OBJECT Chiari malformation Type I (CM-I) is often found in patients with scoliosis. Most previous reports of CM-I and scoliosis have focused on patients with CM-I and a spinal syrinx. The relationship between CM-I and scoliosis in the absence of a syrinx has never been defined clearly. The authors sought to determine if there is an independent association between CM-I and scoliosis when controlling for syrinx status. METHODS The medical records of 14,118 consecutive patients aged ≤ 18 years who underwent brain or cervical spine MRI at a single institution in an 11-year span were reviewed to identify patients with CM-I, scoliosis, and/or syrinx. The relationship between CM-I and scoliosis was analyzed by using multivariate regression analysis and controlling for age, sex, CM-I status, and syrinx status. RESULTS In this cohort, 509 patients had CM-I, 1740 patients had scoliosis, and 243 patients had a spinal syrinx. The presence of CM-I, the presence of syrinx, older age, and female sex were each significantly associated with scoliosis in the univariate analysis. In the multivariate regression analysis, older age (OR 1.02 [95% CI 1.01–1.03]; p < 0.0001), female sex (OR 1.71 [95% CI 1.54–1.90]; p < 0.0001), and syrinx (OR 9.08 [95% CI 6.82–12.10]; p < 0.0001) were each independently associated with scoliosis. CM-I was not independently associated with scoliosis when controlling for these other variables (OR 0.99 [95% CI 0.79–1.29]; p = 0.9). CONCLUSIONS A syrinx was independently associated with scoliosis in a large pediatric population undergoing MRI. CM-I was not independently associated with scoliosis when controlling for age, sex, and syrinx status. Because CM-I is not independently associated with scoliosis, scoliosis should not necessarily be considered a symptom of low cerebellar tonsil position in patients without a syrinx.

Abstract Objectives The relationship between total lymphocyte counts (TLCs) and survival is not well documented in rectal cancer. This study aimed to investigate the association between TLCs and disease-free survival (DFS) and identify factors associated with lymphopenia in locally advanced rectal cancer patients receiving chemoradiotherapy. Methods Thirty-six patients with locally advanced rectal cancer were retrospectively analyzed. TLCs were evaluated before surgery (pre-S), before radiotherapy (pre-RT), and during concurrent chemoradiotherapy (CCRT). The relationship between TLCs and DFS was analyzed by univariate and multivariate analysis. Potential clinical factors associated with lymphopenia were also evaluated. Results Median TLC declined significantly during radiotherapy. Severe lymphopenia during CCRT was significantly associated with poorer DFS on Kaplan-Meier analysis (p=0.01), univariate regression analysis (p=0.036), and multivariate regression analysis (p=0.038). Pre-S TLCs (p=0.009) and pre-RT TLCs (p=0.042) were significantly associated with severe lymphopenia on univariate regression analysis; however, only pre-S TLCs (p=0.026) were significantly associated with severe lymphopenia on multivariate regression analysis. Conclusions Severe lymphopenia was a predictor of poorer DFS in patients with locally advanced rectal cancer receiving adjuvant chemoradiotherapy. Pre-S TLCs were predictors of severe lymphopenia. Further study is warranted to reduce the rate of severe lymphopenia.

Aim. To assess the relationship of serum N-terminal pro-brain natriuretic peptide (NT-proBNP) levels with vascular wall condition and bone mineral density (BMD) in postmenopausal women.Material and methods. The cross-sectional study included 107 outpatients aged 45-82 years who signed informed consent. The inclusion criterion was a menopause during ≥1 year. The level of serum NT-proBNP was determined by electrochemiluminescence. BMD was assessed by dual energy x-ray absorptiometry. Intima-media thickness (IMT), the presence and number of atherosclerotic plaques were evaluated using carotid duplex scanning. Pulse wave velocity (PWV) and augmentation index were estimated by applanation tonometry. To assess 10-year cardiovascular risk, the SCORE high-risk charts were used. Using the Russian model of FRAX® score, 10-year fracture risk was assessed.Results. NT-proBNP level in women with postmenopause >10 years was significantly higher than in those with postmenopause <5 years — 98,7 vs 56,3 pg/ml (p<0,001), but there was no independent relationship according to the regression analysis. According to multivariate regression analysis adjusted for age, menopause duration, systolic blood pressure, hypercholesterolemia, smoking, elevated C-reactive protein and interleukin-6 levels, there were independent relationship between the following parameters: NT-proBNP and IMT (β=2,38, p<0,03), NT-proBNP and PWV (β=1,76, p<0,001). NT-proBNP level in patients with osteoporosis was significantly higher than in women with normal bone mass (p<0,01). A negative correlation was observed between NT-proBNP and BMD of the proximal femur (r=-0,26, p<0,05), while the relationship between BMD of the lumbar vertebrae (L1-L4) and NT-proBNP did not reach significance. In multivariate regression analysis, this relationship has not been confirmed. A positive correlation was obtained between cardiovascular risk (SCORE) and NT-proBNP levels (r=0,28, p<0,001). NT-proBNP levels did not differ in women with a high and low 10-year risk of both major osteoporotic fractures and femoral fractures.Conclusion. An independent relationship of NT-proBNP with vascular stiffness and preclinical atherosclerosis was demonstrated: IMT and PWV. This indicates the participation of NT-proBNP in the atherosclerosis development. The association of elevated NT-proBNP levels with osteoporosis is significant, but not independent, and is apparently related to other factors.
