- Job satisfaction of bioscientists at a Lisbon hospitalPublication . Leitão, Maria do Céu; Abreu, Renato; Bellém, Fernando; Almeida, Ana; Ribeiro-Varandas, Edna; Tavares, Ana SofiaProfessional satisfaction is an important phenomenon due to its influence on the human mental resources and physical health, on their attitudes and on their behaviour, both professional and social. The purpose of this study is to assess the actual level of professional satisfaction of bioscientists working at a Lisbon hospital. A modified questionnaire which allowed the data collection was used for each subject, intended to characterize the sample, order the eight dimensions of professional satisfaction as well determining their levels by using a satisfaction scale. A statistical analysis was made by descriptive methods, Friedman test, Student’s t-test for independent samples and one-way ANOVA. In a sample of 30 technicians (25.42 % of the target-population), the most important dimension was Status/Prestige (7.12) and the least important was Remuneration (3.12). Global satisfaction shows that they are neither satisfied nor dissatisfied, although the dimension Professional-Patient Relation had better results, in opposition to Remuneration, which had the worst outcome. The study concluded that the sample’s level of professional satisfaction is not affected by gender, qualifications, years of technical experience and remuneration. The results reveal a state of accommodation and lack of interest regarding labor, which might be a consequence of the actual stagnation in their career. The replication of this study in other public and private institutions are of the most relevance, in order to obtain representative outcomes concerning the professional satisfaction of bioscientists at a national level.
- Study of biochemical and haematological changes in football playersPublication . Tavares, Ana Sofia; Almeida, Ana; Leitão, Maria do Céu; Ribeiro-Varandas, Edna; Abreu, Renato; Bellém, FernandoBackground - Football players develop throughout their practice, an endurance type exercise. This type of practice is known to cause changes both at the cellular level as well as on muscle enzymes. Modifications are also seen in terms of lipid profile, caused by the faster rate of metabolism of these molecules. The aim of this paper was to study the variation of biochemical and haematological parameters on football players. Methods - Blood samples were drawn from 18 football players undergoing an 8 hour-a-week training program. The following parameters were tested: lipid profile, creatine kinase (CK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST); red blood cells (RBC) and their indices, haemoglobin and haematocrit. Results - The lipid profile showed that the HDL-Cholesterol mean (=53.33 mg/dL) was above the value determined as a target (37.00 mg/dL). The LDL-Cholesterol mean was below the target-value, as it was for the triglycerides. There were no significant differences between the real mean and the target value for total cholesterol. All creatine kinase (CK) values were above the target-value of 77 UI/L. The values obtained for lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) tests did not show any significant difference from targetvalues. No major differences from the target values were seen in terms of the haematological parameters. Conclusions - The results of this study have shown that the practice of physical exercise has caused a modification in the subject's lipid profile, especially on the HDL-C values. Concerning muscle enzymes, the only altered value found was for creatine kinase (CK). The so called sports anaemia was not confirmed.
- The efficiency of urine dipsticks for the diagnosis of urinary tract infectionPublication . Tavares, Ana Sofia; Monteiro, Cátia; Lopes, Inês; Ribeiro-Varandas, Edna; Abreu, Renato; Leitão, Maria do Céu; Bellém, Fernando; Almeida, AnaUrinary tract infection (UTI) is one of the most prevalent pathologies in developed countries, particularly in women, characterized by the presence of bacterial growth in any part of the urinary system. Currently, urine culture is considered the gold standard method for the diagnosis of UTI. However, this method has several disadvantages including the time necessary for obtaining the results and the associated high costs. Therefore, it is important to evaluate new efficient and valuable methods for the diagnosis of these infections. Objectives: Presently, dipsticks are considered a possible valuable alternative to urine culture. This method has very low costs associated and the results can be obtained in few minutes. Here we aim to compare the sensibility, specificity, predictive value of a positive test and a negative test of both methods in order to determine the efficiency of the test strips method and also to characterize the microorganism more frequently isolated.
