PURPOSE OF THE STUDY: This study aimed to investigate the knowledge, attitudes, and practices regarding post-operative pain management among nurses working in the surgical units in Kandy, Sri Lanka.
DESIGN: The study was based on quantitative method, specifically descriptive design. Samples were selected using the probability sampling technique of simple random sampling. The sample size obtained was 200 nurses using 95% confidence level and a 4% margin of error for a population of 300 nurses in the research setting.
METHODS: A self-administered questionnaire was chosen as a data collection method, and this questionnaire contained 36 questions under four sub-topics. A box was kept in the matron office in the surgical section to collect the questionnaire. The data were analyzed using descriptive analysis with percentages.
FINDINGS: According to the research findings, 66% (132) were knowledgeable about the meaning of post-operative pain management. Post-operative pain management was identified by 74% (148) of the respondents, and 26% (52) correctly indicated that the most accurate judge of post-operative pain is the patients' self-report. When considering the attitudes, 66% (132) of the participants agreed that post-operative patients show discomfort before receiving the next analgesics. Among the participants, 60% (120) of nurses worried that patients would become addicted to analgesics that they give, while 20% (40) disagreed, and 2% strongly disagreed. 54% (108) of the nurses stated that patients were kept under close observation and the pain was monitored regularly, while 46% (92) expressed that patient is kept in a comfortable position. To manage post-operative pain, 80% (160) used non-pharmacological methods while 20% (40) did not.
CONSLUSIONS: The findings of this study identified problems such as inadequate knowledge, and inappropriate attitudes and practices regarding postoperative pain management.

Introduction
Of the 55,000 deaths per year due to rabies, 56% occur in Asia and 44% in Africa. Despite the existence of the national rabies control program in Sri Lanka, rabies is still prevalent, suggesting that animal bite victims may have failed to observe the proper first aid measures and seek immediate medical treatment. The purpose of this study is to describe the health-seeking behavior among animal bite victims of a selected population in Kandy District, Sri Lanka. The influences of subjects’ demographic characteristics to these behaviors were studied.
Methods
We conducted face-to-face interviews in May 2006 among households with family members having history of animal bite injuries. Data on health-seeking behaviors such as first aid measure application, immediate medical consultation, and completion of post-exposure prophylaxis (PEP) were obtained. The association between behaviors and demographic characteristics were evaluated using Chi-square test or the Fisher’s exact test.
Results
Of the 6968 sample population, 357 (5.1%) had history of animal bites one year prior to the survey. Most of the subjects performed first aid measures (n=297, 83.2%) and sought medical treatment (n=319, 89.4%) within 24 hours (n=295, 82.6%) of the injury. Only 9.8% (n=35) of the subjects completed the PEP. There was no association between health-seeking behavior and demographic characteristics. Two subjects died having symptoms that resembled rabies without completing the necessary PEP, and two animal specimens were sent for laboratory testing that confirmed one case of feline rabies one year prior to the study.
Conclusion
In general, the health-seeking behaviors of the subjects were not influenced by their demographic characteristics which may contribute to greater difficulties in controlling rabies. To strengthen the rabies control program, effective education of both the public and health sectors by thorough and adequate wound washing, and strict adherence with the recommended treatment schedule is of paramount importance.

Objective:
The relationship between screen use and problematic internet use (PIU; i.e., internet addiction) amongst adolescents has not been sufficiently explored. Further, there is even less research on how gender is associated with this relationship. The goal of the study was to examine adolescent screen use, PIU, and its impact on day-to-day routines of adolescents.
Methods:
Participants were recruited from an outpatient pediatric clinic in São Paulo, Brazil. A total of 180 adolescents completed questionnaires related to their screen use, extracurricular activities, and symptoms of PIU. Univariate and multivariate statistics were used to determine correlates and predictors of PIU, and to explore gender differences.
Results:
A total of 26.1% of adolescents met the criteria for PIU. There were no significant differences between boys and girls in PIU severity. However, there were significant gender differences in preferred use of the Internet, with boys being more likely to access the Internet to play video games (odds ratio [OR]=27.1) and girls being more likely to socialize with friends (OR=4.51). PIU severity increased proportionally to the number of hours of use of all screen devices with moderate-to-large effect sizes (η2=0.060–0.157). Using screens during meals and missing extracurricular activities were both associated with PIU.
Conclusion
Though gender was not associated with PIU, both excessive use of screen devices during meals and neglect of offline extracurriculars activities were identified as risk factors for PIU. Prevention measures should consider the impact of gender and associated patterns of motivation and Internet use.

Obesity, which continues to increase worldwide, was shown to irreversibly impair the differentiation potential and angiogenic properties of adipose tissue mesenchymal stromal cells (ADSCs). Because these cells are intended for regenerative medicine, especially for the treatment of inflammatory conditions, and the effects of obesity on the immunomodulatory properties of ADSCs are not yet clear, here we investigated how ADSCs isolated from former obese subjects (Ex-Ob) would influence macrophage differentiation and polarization, since these cells are the main instructors of inflammatory responses. Analysis of the subcutaneous adipose tissue (SAT) of overweight (OW) and Ex-Ob subjects showed the maintenance of approximately twice as many macrophages in Ex-Ob SAT, contained within the CD68+ /FXIII-A− inflammatory pool. Despite it, in vitro, coculture experiments revealed that Ex-Ob ADSCs instructed monocyte differentiation into a M2-like profile, and under inflammatory conditions induced by LPS treatment, inhibited HLA-DR upregulation by resting M0 macrophages, originated a similar percentage of TNF-α+ cells, and inhibited IL-10 secretion, similar to OW-ADSCs and BMSCs, which were used for comparison, as these are the main alternative cell types available for therapeutic purposes. Our results showed that Ex-Ob ADSCs mirrored OW-ADSCs in macrophage education, favoring the M2 immunophenotype and a mixed (M1/M2) secretory response. These results have translational potential, since they provide evidence that ADSCs from both Ex-Ob and OW subjects can be used in regenerative medicine in eligible therapies. Further in vivo studies will be fundamental to validate these observations.

Pet turtles are well-known to harbor an array of bacterial pathogens which can cause zoonotic infections in humans as well as opportunistic infections in the turtles itself. Essential oils are the natural plant extracts which have been traditionally used for disease treatment. In the present study, the essential oil of lavender (EOL) was examined for its antibacterial activity against thirty-eight strains of turtle-borne pathogenic bacteria belonging to seven species; Aeromonas hydrophila, A. caviae, A. dhakensis, Citrobacter freundii, Proteus mirabilis, Salmonella enterica and Pseudomonas aeruginosa. Antibacterial activity of EOL was tested by means of disk diffusion, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) tests. In addition, the antimicrobial susceptibility pattern of 11 commonly used antimicrobials was examined and the multiple antibiotic resistance (MAR) index was calculated. The results revealed that EOL was active against all tested turtle-borne pathogenic bacteria except P. aeruginosa. The range of MIC and MBC values of EOL against isolates except P. aeruginosa were recorded as 0.5-1% (V/V) and 0.5-2% (V/V), respectively. The MBC/MIC ratio was detected as <4, revealing that the tested EOL was bactericidal. Besides, most of the isolates were resistant to different antimicrobials in antimicrobial disk diffusion test. MAR index values of the tested strains were ranging from 0.27 to 0.91. The outcomes indicate that EOL has a potential to be used as an antibacterial agent against pathogenic bacteria isolated from pet turtles.

Turtle-borne Salmonella enterica owns significance as a leading cause in human salmonellosis. The current study aimed to determine the quinolone susceptibility and the genetic characteristics of 21 strains of S. enterica subsp. enterica isolated from pet turtles. Susceptibility of four antimicrobials including nalidixic acid, ciprofloxacin, ofloxacin, and levofloxacin was examined in disk diffusion and MIC tests where the majority of the isolates were susceptible to all tested quinolones. In genetic characterization, none of the isolates were positive for qnr or aac(6')-Ib genes and no any target site mutations could be detected in gyrA, gyrB, and parC quinolone resistance determining regions (QRDR). In addition, neighbor-joining phylogenetic tree derived using gyrA gene sequences exhibited two distinct clads comprising; first, current study isolates, and second, quinolone-resistant isolates of human and animal origin. All results suggest that studied strains of S. enterica subsp. enterica isolated from pet turtles are susceptible to quinolones and genetically more conserved with regards to gyrA gene region.

INTRODUCTIONThere is limited utilisation of acute stroke reperfusion treatments which have narrow therapeutic windows, with delayed hospital presentation being a major limiting factor in Singapore. Most patients who wake up with symptoms are ineligible for reperfusion treatments as duration from onset time is not known. We studied the profile of wake-up strokes, onset-to-door duration and their associated factors among ischaemic stroke patients in the context of potential new treatments.
MATERIALS AND METHODSThis is an observational study of consecutive ischaemic stroke patients presenting within 2 weeks of symptom onset to the Singapore General Hospital in 2012.
RESULTSOf the 642 ischaemic stroke patients studied, 33% of the cases were wake-up strokes [median age 64 years, 88%<80 years; median NIHSS score 4, 98%<20]. The median onset-to-door duration was 14.3 hours (Interquartile range, 4.8 to 38.2 hours), 20% of them arrived <3.5 hours (considering eligibility for intravenous alteplase in the proven 4.5 hours window accounting for a one hour door-to-needle duration), 14%: ≥3.5 to <8 hours, 11%: ≥8 to <12 hours, and 56%: ≥12 hours. Most patients with known stroke risk factors including atrial fibrillation (66%), hypertension (78%) and prior stroke (81%) presented beyond 3.5 hours.
CONCLUSIONThe one- third proportion of wake-up stroke in this cohort and low prevalence of relative contraindications suggest this is a promising group for emerging thrombolysis indications. With the majority of patients presenting after 8 hours, widening of the therapeutic window with new potential reperfusion treatments would not appreciably increase treatment utilisation. This study reaffirms the urgent need for public education to improve stroke awareness in Singapore.
