Background: The horse intestinal tract is sensitive and contains a highly complex microbial population. A shift in the microbial population can lead to various issues such as inflammation and colic. The use of nutraceuticals in the equine industry is on the rise and curcumin is thought to possess antimicrobial properties that may help to minimize the proliferation of opportunistic bacteria. Methods: Four cecally-cannulated horses were utilized to determine the optimal dose of liposomal-curcumin (LIPC) on reducing Streptococcus bovis/equinus complex (SBEC), Escherichia coli K-12, Escherichia coli general, Clostridium difficile, and Clostridium perfringens in the equine hindgut without adversely affecting cecal characteristics. In the first study cecal fluid was collected from each horse and composited for an in vitro, 24 h batch culture to examine LIPC at four different dosages (15, 20, 25, and 30 g) in a completely randomized design. A subsequent in vivo $4{\times}4$ Latin square design study was conducted to evaluate no LIPC (control, CON) or LIPC dosed at 15, 25, and 35 g per day (dosages determined from in vitro results) for 9 days on the efficacy of LIPC on selected bacterial strains, pH, and volatile fatty acids. Each period was 14 days with 9 d for acclimation and 5 d withdrawal period. Results: In the in vitro study dosage had no effect ($P{\geq}0.42$) on Clostridium strains, but as the dose increased SBEC concentrations increased (P = 0.001). Concentrations of the E. coli strain varied with dose. In vivo, LIPC's antimicrobial properties, at 15 g, significantly decreased (P = 0.02) SBEC when compared to 25 and 35 g dosages. C. perfringens decreased linearly (P = 0.03) as LIPC dose increased. Butyrate decreased linearly (P = 0.01) as LIPC dose increased. Conclusion: Further studies should be conducted with a longer dosing period to examine the antimicrobial properties of curcumin without adversely affecting cecal characteristics.

The osmotic and mechanical red cell fragility of the professional blood donors, who were found to be anemic as the result of frequent and repeated blood loss the past 5-6 years, were compared with that of the normal person while incubating the blood at $4-6^{\circ}C$ for 28 days. The fragility was expressed as % hemolysis occured during the incubation, and the following results were obtained: 1. The osmotic fragility in the normal persons (i.e, ; control group) progressively increased as the incubation became longer, and % hemolysis in 0.42% NaCl solution at 0, 10, 15, 21 and 28 incubation day was 31.90, 50.20, 41.68, 43.50 and 55.40 respectively. The mechanical fragility. in the normal red cells ranged between the minimum of 0.00% to the maximum of 5.80% both in 0.90 and 0.66% of NaCl solutions. 2. The hemolysis curve obtained in the red cell osmotic fragility from three cases of the anemic persons (i.e,; experimental group) showed a significant left side shift comparing with the normal in general which indicates that the fragility was more increased in the experimental group. The mechanical fragility in the experimental group ranged between the minimum 0.00% to the maximum 19.00% both in 0.90 and 0.66% of NaCl solutions. 3. The red cells of the chronic anemic person due to the frequent blood loss as the professional blood donor exhibit significantly marked increase both in osmotic and mechanical fragility comparing with the normal, and the tendency was more prominent as the incubation period became longer.

Background: Soft tissue asymmetry such as lip canting or deviation of the philtrum is an important influencing factor for unbalanced facial appearance. Lip canting could be improved by the correction of the occlusal canting or positional change of the mentum. Although there are many studies about changes of lip canting, however, postoperative changes of philtrum deviation have not been yet reported. In this study, we investigate the positional change of the philtrum after orthognathic surgery and influencing factors. Methods: Positional change of the philtrum was evaluated in 41 patients with facial asymmetry who underwent bimaxillary surgery, in relation to other anatomical soft tissue landmarks using a frontal clinical photo. The surgical movement of the maxillary and mandibular dental midline and canting were measured in postero-anterior cephalogram before and 1 day after surgery. The same procedure was repeated in patients with more than 1.5 mm perioperative change of the mandibular dental midline after bimaxillary surgery. Results: Maxillary dental midline shifting and canting correction did not have a significant correlation with lateral movement of the philtrum midline. However, the mandibular shift had a statistically significant correlation with a lateral movement of the philtrum (p < 0.05) as well as other linear parameters and angle values. Conclusion: The horizontal change of the philtrum is influenced by lateral mandibular movement in patients with facial asymmetry, rather than maxillary lateral movement.

Purpose: The aim of this study was to elucidate clinical nurses' ethics germane to information literacy and perception of patient data privacy and thus help nurses to develop more positive and consolidated ethical values. Methods: For this study a descriptive survey design was used. Participants were 142 nurses who worked in a hospital and completed self-report questionnaires. Data were collected from August 1 to 5, 2016 and were analyzed using independent t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation coefficients, and stepwise multiple regression with SPSS 22.0. Results: Ethical value had a positive correlation with information needs (r=.25, p=.002) in information literacy as well as in direct patient care (r=.27, p=.001), shift work (r=.20, p=.016), patient information management (r=.39, p<.001), and communication (r=.24, p=.004) in perception of patient data privacy. Patient information management, educational background, and age were significant variables predicting the level of ethical values and accounted for 21% of the variance. Conclusion: Ethical values education with particular emphasize on managing patient information should be encouraged for nurses who are younger and have a lower education level. Findings indicate a need for education programs to guide clinical nurses to utilize appropriate information when solving ethical challenges in every day nursing practice.

Purpose: This study aimed to investigate the relationships among job characteristics, knowledge sharing, organizational culture, and organizational commitment in occupational health nurses (OHN) and clinical nurses (CN) to identify factors that might influence organizational commitment. It aimed to contribute to the improvement of knowledge management in health care organizations, including industrial workplaces and hospitals. Methods: A convenience sample of 188 nurses, specifically 100 OHN and 88 CN, was selected. Data were analyzed with descriptive statistics, t-tests, correlation coefficients, and multiple regression analysis. Results: OHNs had a significantly higher education level and current work experience; higher proportion of participants with contract employment status, day work shift, less turnover experience, good lifestyle; and higher scores on organizational culture ($3.3{\pm}0.61$) and organizational commitment ($3.1{\pm}0.60$). Additionally, the correlations among organizational commitment, job characteristics, knowledge sharing, and organizational culture ware higher (r=.38~.57) among OHNs as compared to those among CNs. Further, the organizational commitment of OHNs was significantly influenced by knowledge sharing, organizational culture, working hours, and salary ($R^2=.32$), while that of CNs was influenced by organizational culture and life event stress ($R^2=.11$). Conclusion: There is a need to develop measures to enable nurses to contribute to the improvement of knowledge management in health care organizations as major human resources, by including interventions for the major factors leading to between-group differences in organizational performance.

This study aims to determine the effect of a trained dedicated dietitian on clinical outcomes among Lebanese hemodialysis (HD) patients: and thus demonstrate a viable developing country model. This paper describes the study protocol and baseline data. The study was a multicenter randomized controlled trial with parallel-group design involving 12 HD units: assigned to cluster A (n = 6) or B (n = 6). A total of 570 patients met the inclusion criteria. Patients in cluster A were randomly assigned as per dialysis shift to the following: Dedicated Dietitian (DD) (n = 133) and Existing Practice (EP) (n = 138) protocols. Cluster B patients (n = 299) received Trained Hospital Dietitian (THD) protocol. Dietitians of the DD and THD groups were trained by the research team on Kidney Disease Outcomes Quality Initiative nutrition guidelines. DD protocol included: individualized nutrition education for 2 hours/month/HD patient for 6 months focusing on renal osteodystrophy and using the Trans-theoretical theory for behavioral change. EP protocol included nutrition education given to patients by hospital dietitians who were blinded to the study. The THD protocol included nutrition education to patients given by hospital dietitian as per the training received but within hospital responsibilities, with no set educational protocol or tools. Baseline data revealed that 40% of patients were hyperphosphatemics (> 5.5 mg/dl) with low dietary adherence and knowledge of dietary P restriction in addition to inadequate daily protein intake ($58.86%{\pm}33.87%$ of needs) yet adequate dietary P intake ($795.52{\pm}366.94$ mg/day). Quality of life (QOL) ranged from 48-75% of full health. Baseline differences between the 3 groups revealed significant differences in serum P, malnutrition status, adherence to diet and P chelators and in 2 factors of the QOL: physical and social functioning. The data show room for improvement in the nutritional status of the patients. The NEMO trial may be able to demonstrate a better nutritional management of HD patients.

Diesel vehicles are a significant source of fine carbon particle emissions including polynuclear aromatic hydrocarbons (PAHs). Urinary 1-hydroxypyrene (1-OHP) is firmly established as a useful biomarker of PAHs uptake in human. To investigate the exposure effect of PAHs in miners according to using diesel truck which was for transportation of ore, we measured urinary 1-OHP as the PAHs exposure biomarker, and analyzed the relationship between urinary 1-OHP concentration and using diesel truck. The study was performed on 118 workers (56 miners in factories using diesel truck, 62 miners in factories non-using diesel truck) and 21 controls. Urine samples were obtained at the end of shift on the survey day. There was no significance in comparison with the mean concentrations on urinary 1-OHP by age, BMI, work duration, smoking, drinking and ventilation type. But significant difference were found among urinary 1-OHP concentrations on factories according to using diesel truck (p=0.000). The urinary 1-OHP mean concentration on underground miners using diesel truck ($0.54{\mu}mol/mol$ creatinine) was higher than those of surface miners using diesel truck ($0.33{\mu}mol/mol$ creatinine, p=0.028), underground miners non-using diesel truck ($0.32{\mu}mol/mol$ creatinine, p=0.001) and controls ($0.22{\mu}mol/mol$ creatinine, p=0.000). In comparison with using status diesel truck, the urinary 1-OHP mean concentration of underground miners using diesel trucks was higher than those of other mine status. The study results would be beneficial to future environmental and biological studies of PAHs exposure to diesel exhaust in mines.

Background: Urinary 1-hydroxypyrene (1-OHP) was selected as a biomarker of polycyclic aromatic hydrocarbons (PAHs) to explore the accumulation level in the bodies of workers at rubber smoke sheet factories in southern Thailand. Methods: Spot urine samples were taken from four groups of workers from June 2006 to November 2007. The nonexposure or control groups included habitual cigarette smokers and nonsmokers. The other two groups were workers exposed to particle-bound PAHs from rubber wood smoke and they were nonsmokers. All spot urine samples were analyzed for 1-OHP and creatinine levels. Results: The mean${\pm}$standard deviation urinary 1-OHP in the control group of habitual smokers and the nonsmokers was $0.24{\pm}0.16{\mu}mol/mol$ creatinine and not-detected to $0.14{\mu}mol/mol$ creatinine, respectively. In the workers, the 1-OHP levels on workdays had no significant difference from the 1-OHP levels on the days off. The yearly average 1-OHP level was $0.76{\pm}0.41{\mu}mol/mol$ creatinine whereas the average 1-OHP level during 10 consecutive workdays was $1.06{\pm}0.29{\mu}mol/mol$ creatinine (p > 0.05). Conclusion: The urinary 1-OHP levels of workers exposed to PAHs were high. The accumulation of 1-OHP in the body was not clear although the workers had long working hours with few days off during their working experience. Therefore, a regular day off schedule and rotation shift work during high productive RSS should be set for RSS workers.
