Introduction:
We hypothesized that patients are poorly informed about proper procedure for 24-hour urine specimen collection and its relevance in determination of biochemical analytes, despite availability of leaflets and webpage with instruction for collection. The aim of this survey was to question outpatients how well are they informed about procedure of 24-hour urine specimen collection.Materials and methods:
The survey with 10 questions was done in outpatient laboratory of University Department of Chemistry, Medical School University Hospital Sestre Milosrdnice, Zagreb, Croatia. The study included 59 patients with collected 24-hour urine sample who have consented to participate in the survey.Results:
Out of 59 participants, most of them (0.97) were older than 40 years. Internet was not recognized as a source of information (1/59). Almost one third of the patients have changed their drinking habits to collect more urine volume. Although most of the patients (0.60) were aware that the bottle of water is the best choice for the container, almost half of them were collected urine samples in the plastic soft drink bottle. Laboratory staff and physicians often have given information about proper collection procedure, but that information was insufficient.Conclusions:
Patients are usually not aware of importance of proper preanalytical procedure for collecting urine specimen and how improper collection could affect results of requested tests. Education of outpatients, general practitioners and laboratory staff is needed in order to improve sample quality and trueness of results. 相似文献33.

IntroductionThe aims of study were to assess: 1) performance specifications of Atellica 1500, 2) comparability of Atellica 1500 and Iris, 3) the accuracy of both analysers in their ability to detect bacteria.Materials and methodsCarryover, linearity, precision, reproducibility, and limit of blank (LoB) verification were evaluated for erythrocyte and leukocyte counts. ICSH 2014 protocol was used for estimation of carryover, CLSI EP15-A3 for precision, and CLSI EP17 for LoB verification. Comparison for quantitative parameters was evaluated by Bland-Altman plot and Passing-Bablok regression. Qualitative parameters were evaluated by Weighted kappa analysis. Sixty-five urine samples were randomly selected and sent for urine culture which was used as reference method to determine the accuracy of bacteria detection by analysers.ResultsAnalytical specifications of Atellica 1500 were successfully verified. Total of 393 samples were used for qualitative comparison, while 269 for sediment urinalysis. Bland-Altman analysis showed statistically significant proportional bias for erythrocytes and leukocytes. Passing-Bablok analysis for leukocytes pointed to significant constant and minor proportional difference, while it was not performed for erythrocytes due to significant data deviation from linearity. Kappa analysis resulted in the strongest agreements for pH, ketones, glucose concentrations and leukocytes, while the poorest agreement for bacteria. The sensitivity and specificity of bacteria detection were: 91 (59-100)% and 76 (66-87)% for Atellica 1500 and 46 (17-77)% and 96 (87-100)% for Iris.ConclusionThere are large differences between Atellica 1500 and Iris analysers, due to which they are not comparable and can not be used interchangeably. While there was no difference in specificity of bacteria detection, Iris analyser had greater sensitivity. 相似文献

Introduction:
Proper preparation of the individual is a key prerequisite for ensuring the quality of laboratory testing. Our hypothesis was that many outpatients are not sufficiently familiar with the correct way of preparing for the laboratory tests, for which the individual needs to be at fasting. This study aimed to investigate: i) whether patients are aware of how they need to prepare properly for laboratory tests; ii) the way in which users are informed about how to prepare for laboratory testing; and iii) whether users arrive to the laboratory for phlebotomy properly prepared.Materials and methods:
An anonymous questionnaire was conducted on 150 outpatients older than 18 years, during February 2013. The response rate was 11%. All patients were interviewed by the laboratory staff. Patients were informed about detail of the questionnaire and agreed to participate in the survey.Results:
Out of the total number subjects, 39% were fully aware of the proper definition of the fasting, whereas even 46% subjects replied that the last meal has to be taken the day before and the exact time that must pass after the last meal to blood sampling is not important. Furthermore, 52% subjects did not receive any information about how they need to prepare themselves properly for blood testing. Only 60% of them came properly prepared for the laboratory blood testing.Conclusions:
Substantial proportion of patients do not come properly prepared for laboratory testing. We conclude that patients are not well informed about the fasting requirements for laboratory blood testing. Moreover, requesting physician is the preferred source of information from which patients learn how to prepare themselves for phlebotomy. 相似文献37.

Academic dishonesty in higher education is an increasingly visible problem throughout the world and in Romania in particular. A total of 1127 university students from six public Romanian universities were surveyed for their experiences and beliefs with 22 behaviors that might be considered academically dishonest. A five-factor solution to the frequencies of these behaviors was interpretable and accounted for more than half of the total variance. How acceptable students believed the behaviors were and how often students witnessed other students engage in these behaviors were consistent predictors of the frequency of the behaviors, with small to medium effect sizes. Demographic predictors of these behaviors, including gender, academic specialty, year in school, institution, grade average, and scholarship status, predicted very little variance in the behaviors. Implications and limitations of the study, as well as limitations of research in the field, are discussed. 相似文献

OBJECTIVE: This retrospective, cross-sectional study explored the hypothesis that multiple forms of child abuse and neglect (child multi-type maltreatment; CMM) would be associated with women's lower social support and higher stress in adulthood, and that this, in turn, would amplify their vulnerability to symptoms of depression and posttraumatic stress disorder (PTSD). METHOD: Participants were 100 women recruited from an inner-city gynecological treatment center for low-income women. Data were analyzed via structural equation modeling (SEM) with Lisrel 8.0. RESULTS: CMM was directly predictive of decreased social support and increased stress in adulthood. CMM was also directly predictive of PTSD symptoms, but not depression symptoms in adulthood. Social support partially mediated the relationship between CMM and adult PTSD symptoms, and stress fully mediated the relationship between CMM and adult symptoms of depression. CONCLUSIONS: Findings support both direct and mediational effects of social resources on adult depression and PTSD symptoms in women with histories of CMM, suggesting that resources are key factors in psychological adjustment of CMM victims. 相似文献

IntroductionEpithelial cells (ECs) are structures regularly observed during urine microscopy analysis. The correct identification of EC subtypes can be useful since renal tubular epithelial cells (RTECs) are clinically relevant. We investigate the urinary ECs report and the judgement of its clinical importance by Brazilian laboratories.Materials and methodsA survey with four questions was made available to participants of the Urinalysis External Quality Assessment Program (EQAP) from Controllab. Laboratories composed 3 groups: (1) differentiating ECs subtypes: “squamous”, “transitional” and “RTECs”; (2) differentiating ECs subtypes: “squamous” or “non-squamous” cells; (3) without ECs subtype identification. Participants did not necessarily answer to all questions and the answers were evaluated both within the same laboratory’s category and within different categories of laboratories.ResultsA total of 1336 (94%) laboratories answered the survey; Group 1, 119/140 (85%) reported that ECs differentiation is important to the physician and 62% want to be evaluated by EQAP, while in Group 3, 455/1110 (41%) reported it is useful to them, however only 25% want be evaluated by EQAP. Group 2 laboratories 37/51 (73%) reported that the information is important, but only 13/52 (25%) are interested in an EQAP with differentiation of the 3 ECs subtypes.ConclusionMost of the laboratories do not differentiate ECs in the three subtypes, despite the clinical importance of RTECs. Education of laboratory staff about the clinical significance of urinary particles should be considered a key priority. 相似文献

This paper attempts to measure the effect of non-formal training on the employment and earnings of Peruvian male and female workers. The main findings are: (i) workers with limited educational attainment face limited training opportunities; (ii) training significantly improves the employment probabilities, but not the earnings, of private-sector employed or self-employed women; (iii) while training does not affect the employment probabilities of men, it affects significantly wage gains of those employed in the private sector and; (iv) regardless of gender, training does not increase the earnings of self-employed workers. 相似文献
