Abstract Study design: Retrospective cohort studySummary of Background Data：Restoring the sagittal balance is the significant procedure, which could be evaluated by the relationship of thoracic kyphosis (TK) and lumbar lordosis (LL). Several lumbar lordosis predictive formulas have been proposed. But previous study ignored importance of reciprocal relationship between regional spinal modifications in some ways.Objectives: Realignment of the lumbar lordosis is fundamental in spinal surgery and several formulas have been established to predict the appropriate lumbar lordosis. However, the predictive accuracy of these formulas did not reach their targets. The present study introduced a novel predictive formula for realignment of lumbar lordosis in correction surgery, aiming to predict the individualized ideal lumbar lordosis for different patients.Methods: A total of 311 asymptomatic volunteers were recruited: 220 volunteers for the development of the formula, and the other 91 subjects for validation. General and radiological parameters were evaluated. Correlation analysis between maxLL and other parameters was performed. Multiple regression analysis was conducted to establish the predictive formula using variables related to maxLL. Comparison between predicated maxLL yielded by our formula and other 7 formulas and actual maxLL were conducted to determine the reliability and validity of our predictive formula.Results: MaxLL was correlated with maxTK, SS, PT and PI (all P<0.05). The adjusted multiple regression analysis showed that there were significant associations of maxLL with maxTK and PI (all P<0.001), and the formula was established as follows: maxLL=0.6*maxTK+0.5*PI+3. No significant difference was found between actual maxLL and predicted maxLL yielded by our formula (P=0.408), and our predictive formula has been demonstrated sound reliability and validity. Conclusion: MaxTK and PI were the primary contributors to maxLL, and our novel formula could be safely utilized to predict the ideal lumbar lordosis for patients before surgery.

Aims: This study aimed to assess the current levels of job and workplace satisfaction among community pharmacists (CPs) and to explore the factors that can affect their job and workplace satisfaction. Methods: A self-administered research tool (questionnaire) was developed based on previously published literature. After its reliability and validity measurements, the questionnaire was distributed to the target population and data was collected. Data were entered into Statistical Package for Social Science (SPSS) ver. 22.0 and analyzed using descriptive statistics, chi-square, and multiple regression analysis. The level of significance (α) was set at 0.05. Results: CPs reported high satisfaction (76.7%) concerning their jobs. Only 23.3% of them were not satisfied with their current job. Univariate analysis showed that job and workplace satisfaction among CPs was not significantly associated with gender, age, length of service, position and salary. However, the univariate analysis demonstrated a significant difference between practice settings and job and workplace satisfaction with p = 0.013. Among the respondents, those who worked in the chain pharmacies (83.7%) expressed greater job and workplace satisfaction, which is 16% higher than those working in independent pharmacies (67.6%). Therefore, practice setting was shown as the predictor of job and workplace satisfaction among CPs by using multiple regression analysis. Conclusion: Overall, CPswere relatively satisfied with their current job. Our results had reinforced previous studies that reported that practice settings can affect pharmacists’ job and workplace satisfaction.

AbstractThe effects of intravenous sedation with midazolam on the cerebral function of elderly patients with severe dementia are unclear. This study aimed to evaluate its effects on parameters such as brainwaves and cerebral blood flow (CBF) and compare them between elderly individuals with dementia and without cognitive impairment. Ten patients with severe dementia and 10 without cognitive impairment were registered. The bispectral index (BIS) and normalized tissue hemoglobin index (nTHI), which reflects CBF using near-infrared spectroscopy, were measured. Midazolam was administered until a Modified Observer’s Assessment of Alertness/Sedation score of 2 was reached. The chi-squared, Mann–Whitney U, Wilcoxon signed-rank, and Friedman tests and multiple regression analysis were used for comparisons. Whereas a similar decline in BIS values was observed in both groups after midazolam administration (P < 0.018), there was a significant decrease by 9% in the nTHI of the dementia-positive group (P < 0.013). However, there was no significant difference in the nTHI between the dementia-positive and dementia-negative group according to the multiple regression analysis (P = 0.058). In the dementia-negative group, none of the measured values differed from the baseline values. In the dementia-positive group, sedation with midazolam resulted in a 9% decrease in the CBF.

The purpose of this study is to examine the impact and the electronic service quality of the national zakat management information system (SIMBA) on the national zakat collection. This paper uses a multiple regression analysis in its explorative attempt to illustrate the impact of SIMBA implementation on the national zakat collection. It shows that SIMBA is positive and significantly impact the national zakat collection as well as the human development index that is used as a proxy for the human resource management quality of zakat institutions in the respective city. Nonetheless, the population is negative and significant to the zakat collection as endemic poverty and reluctance to pay zakat are indicated as the reasons. Moreover, this study has succeeded in adapting and conducting e-service quality survey to zakat information system realm. All the tests prove that the instrument in this study has a high degree of reliability and validity. The results show that some of the demographic factors significantly impact the perceived performance of SIMBA. Multiple regression analysis that is conducted in this study shows that e-service quality dimension is positive and significant towards SIMBA’ overall quality, perceived value, and loyalty intention. This study contributes to the zakat management system literature, especially in the impact of the national zakat information system, which is pivotal in enhancing zakat collection and poverty alleviation program funded by zakat.

Abstract Background This study aimed to investigate the association of acute kidney injury (AKI) with change in estimated glomerular filtration rate (eGFR) in children with advanced chronic kidney disease (CKD). Methods Single centre, retrospective longitudinal study including all prevalent children aged 1–18 years with nondialysis CKD stages 3–5. Variables associated with CKD were analysed for their potential effect on annualised eGFR change (ΔGFR/year) following multiple regression analysis. Composite end-point including 25% reduction in eGFR or progression to kidney replacement therapy was evaluated. Results Of 147 children, 116 had at least 1-year follow-up in a dedicated CKD clinic with mean age 7.3 ± 4.9 years with 91 (78.4%) and 77 (66.4%) with 2- and 3-year follow-up respectively. Mean eGFR at baseline was 29.8 ± 11.9 ml/min/1.73 m2 with 79 (68%) boys and 82 (71%) with congenital abnormalities of kidneys and urinary tract (CAKUT). Thirty-nine (33.6%) had at least one episode of AKI. Mean ΔGFR/year for all patients was − 1.08 ± 5.64 ml/min/1.73 m2 but reduced significantly from 2.03 ± 5.82 to − 3.99 ± 5.78 ml/min/1.73 m2 from youngest to oldest age tertiles (P < 0.001). There was a significant difference in primary kidney disease (PKD) (77% versus 59%, with CAKUT, P = 0.048) but no difference in AKI incidence (37% versus 31%, P = 0.85) between age tertiles. Multiple regression analysis identified age (β = − 0.53, P < 0.001) and AKI (β = − 3.2, P = 0.001) as independent predictors of ΔGFR/year. 48.7% versus 22.1% with and without AKI reached composite end-point (P = 0.01). Conclusions We report AKI in established CKD as a predictor of accelerated kidney disease progression and highlight this as an additional modifiable risk factor to reduce progression of kidney dysfunction.

And Training

Orientation: Extra role behaviours, also known as organisational citizenship behaviours, are very important for an organisation’s success. Organisational objectives can be efficiently achieved when employees are willing to do work that is beyond their job description. Organisations with employees with high organisational citizenship behaviour have a competitive advantage and are highly productiveResearch purpose: The study investigated the influence of compensation and training and development on organisational citizenship behaviour amongst academic staff at a rural-based South African institution of higher learning.Motivation for the study: Research on the influence of compensation and training and development on organisational citizenship behaviour is not new. However, the studies were carried out in different sectors outside South Africa. There is still scant information known about citizenship behaviour in the higher education sector in general and in South African rural-based institutions of higher learning in particular.Research approach/design and method: The study was based on a quantitative approach, which used a cross-sectional research design. A sample of 152 academic staff participated in this study. Data were gathered using a self-administered questionnaire. Descriptive statistics, correlation and multiple regression analysis technique were conducted using Statistical Package for Social Sciences (SPSS) version 26.0.Main findings: The findings revealed a significant relationship between compensation and organisational citizenship behaviour. A significant correlation was also found between training and development and organisational citizenship behaviour. However, in multiple regression analysis, compensation was found to be the only predictor of organisational citizenship behaviour. Moreover, no significant difference in levels of organisational citizenship behaviour between men and women was found.Practical/managerial implications: The management of the institution should continuously review its compensation or rewards policies to enhance organisational citizenship behaviour amongst the academic staff. Institutions of higher learning should also compensate their employees and develop them fairly regardless of gender in order to promote organisational citizenship behaviour.Contribution/value-add: The study’s findings will assist the university management in making strategic decisions on compensation systems and staff development that will enhance the citizenship behaviour of the academic staff.

Seaweed-Kappaphycus-Euchema Cottonii and Denticulum species was first cultivated at Sabah side of Sebatik in 2009. By November 2014, sixty one Sabahan seaweed farmers cultivated 122 ha or 3,050 long lines. Thirty Sabahan seaweed farmers in Kampung Pendekar (3.2 m.t dried) and 31 in Burst Point (12.5 m.t dried) produced 16 metric tonnes of dried seaweed contributed 31% to Tawau’s total production (51 m.t). The remaining 69% were from farmers in Cowie Bay that separates Sebatik from municipality of Tawau. Indonesian in Desa Setabu, Sebatik started in 2008. However, the number of Indonesian seaweed farmers, their cultivated areas and production (as well as quality) in Sebatik increased many times higher and faster than the Sabah side of Sebatik. In 2009 more than 1,401 households in Kabupaten Nunukan (including Sebatik) cultivated over 700 ha and have produced 55,098.95 and 116, 73 m.t dried seaweed in 2010 and 2011 respectively. There is a divergence in productions from farming the sea off the same island under similar weather conditions. Which of the eight explanatory factors were affecting production of seaweeds in Sebatik? Using Cobb Douglas production function, Multiple Regression analysis was conducted on 100 samples (50 Sabahan and 50 Indonesian). Results; Variable significant at α = 0.05% are Experience in farming whereas Farm size; Quantity of propagules and Location — Dummy are the variables significant at α 0.01%. Not significant are variables Fuel; Age; Number of family members involved in farming and Education level.
