Sensitive Troponin Assays: Diagnostic and Prognostic Use in Cardiology

Cardiac troponins (cTns) are the recommended biochemical markers in the diagnosis of myocardial infarction (MI). They are very sensitive and tissue-specific but are limited by their delayed appearance in the circulation. Biochemical markers with more rapid release kinetics, e.g. myoglobin and especially heart-type fatty acid-binding protein (H-FABP), have been used to enhance the early identification of MI. The implementation of cTns into clinical practice has shown that cardiomyocyte injury occurs in many other clinical conditions than MI. The aim of this study was to evaluate the impact of modern and highly sensitive cTnI assays on the early diagnosis of MI. In a patient cohort with suspected MI, such a sensitive cTnI assay enhanced the early diagnostic accuracy when compared to a less sensitive cTnI assay and to myoglobin. When compared to H-FABP during the early hours after symptom onset, the sensitive cTnI assay showed at least similar and, after 6 hours, superior diagnostic accuracy. A positive cTnI test result had superior prognostic value when compared to H-FABP, even among early presenters. The prognostic value of cTn in acute heart failure (AHF) was evaluated in 364 patients who participated in the FINN-AKVA study. The patients presented with AHF but no acute coronary syndrome (ACS). Up to half of the patients had elevated cTn levels which were associated with higher 6-month mortality. The magnitude of cTn elevation was directly proportional to mortality. Finally, the clinical spectrum of cTnI elevations was evaluated in 991 cTnI positive emergency department (ED) patients. 83% of the patients had MI and 17% had cTnI elevation due to other clinical conditions. The latter patient group was characterized by lower absolute cTnI levels and – importantly – higher in-hospital mortality when compared to the MI patients. In conclusion, the use of a highly sensitive cTnI assay enhances the early diagnostic accuracy and risk stratification in suspected MI patients. Cardiac troponin elevations are highly prevalent also in other acute clinical conditions and indicate an adverse outcome of these patients.

Professional development among educators pursuing a B.Ed. program in special education in Tanzania : a study of motives and perceived outcomes

Implementation of different policies and plans aiming at providing education for all is a challenge in Tanzania. The need for educators and professionals with relevant knowledge and qualifications in special education is substantial. Teacher education does not equip educators with sufficient knowledge and skills in special education and professional development programs in special education are few in number. Up to 2005 no degree programs in special education at university level were available in Tanzania. The B.Ed. Special Education program offered by the Open University of Tanzania in collaboration with Åbo Akademi University in Finland was one of the efforts aimed at addressing the big national need for teachers and other professionals with degree qualifications in special education. This pilot program offered unique possibilities to study professional development in Tanzania. The research group in this study consisted of the group of students who participated in the degree program 2005-2007. The study is guided by three theoretical perspectives: individual, social and societal. The individual perspective emphasizes psychological factors as motives, motivation, achievement, self-directed behavior and personal growth. Within social perspective, professional development is viewed as situated within the social and cultural context. The third perspective, the societal, focuses on change, reforms, innovations and transformation of school systems and societies. Accordingly, professional development is viewed as an individual, social and societal phenomenon. The overall aim of the study is to explore the participants’ motives for participating in a B.Ed. Special Education program and the perceived outcomes of the program in terms of professional development. In order to achieve the objectives of the study, a case study approach was adopted. Questionnaires and semi-structured interviews were administered in three waves between January 2007 and February 2009 to the 35 educators participating in the B.Ed. Special Education program. The findings of the study reveal that the participants expressed motives which were related to job performance, knowledge, skills, academic degree and career. Also altruistic motives were expressed by the participants in terms of helping and supporting students with special needs and their communities. The perceived outcomes of the program were in line with the expressed motives. However, the results indicate that the participants also learned new skills, as interaction skills and guidance and counseling skills. Increased self-confidence was also mentioned as an outcome. The participants also got deepened understanding of disability issues. In addition, they learned strategies for creating awareness of persons with disability in the communities. Thus the findings of the study indicate positive outcomes of the program in terms of professional development. The conclusion of the study is that individual, social and societal factors interact when it comes to explaining why Tanzanian educators in special education choose to pursue a degree program in special education. The individual motives, as increased knowledge and better prospects of career development interact with the social and societal motives to help and support vulnerable student groups. The study contributes to increased understanding of the complexity of professional development and of the realities educators meet when educational reforms are implemented in a developing country.

A Brazilian glycoprotein E-negative bovine herpesvirus type 1.2a (BHV-1.2a) mutant is attenuated for cattle and induces protection against wild-type virus challenge

The authors previously reported the construction of a glycoprotein E-deleted (gE-) mutant of bovine herpesvirus type 1.2a (BHV-1.2a). This mutant, 265gE-, was designed as a vaccinal strain for differential vaccines, allowing the distinction between vaccinated and naturally infected cattle. In order to determine the safety and efficacy of this candidate vaccine virus, a group of calves was inoculated with 265gE-. The virus was detected in secretions of inoculated calves to lower titres and for a shorter period than the parental virus inoculated in control calves. Twenty one days after inoculation, the calves were challenged with the wild type parental virus. Only mild signs of infection were detected on vaccinated calves, whereas non-vaccinated controls displayed intense rhinotracheitis and shed virus for longer and to higher titres than vaccinated calves. Six months after vaccination, both vaccinated and control groups were subjected to reactivation of potentially latent virus. The mutant 265gE- could not be reactivated from vaccinated calves. The clinical signs observed, following the reactivation of the parental virus, were again much milder on vaccinated than on non-vaccinated calves. Moreover, parental virus shedding was considerably reduced on vaccinated calves at reactivation. In view of its attenuation, immunogenicity and protective effect upon challenge and reactivation with a virulent BHV-1, the mutant 265gE- was shown to be suitable for use as a BHV-1 differential vaccine virus.

Comparative pathogenicity of bovine herpesvirus 1 (BHV-1) subtypes 1 (BHV-1.1) and 2a (BHV-1.2a)

The study aimed to examine the capacity of two bovine herpesvirus type 1 (BHV-1) isolates of different subtypes (EVI 123/96, BHV-1.1; SV265/98, BHV-1.2a) to induce respiratory disease in calves. These two isolates are representative of the BHV-1 subtypes prevalent in Brazil. Viral subtypes were confirmed by monoclonal antibody analysis and by restriction enzyme digestion of viral genomes. The viruses were inoculated intranasally into seven 3 months old calves (four with BHV-1.1, three with BHV-1.2a). Three other calves of identical age and condition were kept as uninfected controls. In both groups of infected calves, the clinical signs observed were consistent with typical infectious bovine rhinothracheitis (IBR), including pyrexia, apathy, anorexia, nasal and ocular mucopurulent discharges, erosions on the nasal mucosa, conjunctivitis, lachrymation, redness of nasal mucosa, dyspnoea, coughing, tracheal stridor and enlargement of retropharingeal, submandibular and cervical lymphnodes. No significant differences were observed between the clinical scores attributed to both groups. Virus shedding in nasal and ocular secretions were also similar, apart from a significant difference in nasal virus shedding on day 1 to 3 post-inoculation, which was higher for BHV-1.1 than for BHV-1.2a. Following corticosteroid induced reactivation of the latent infection, recrudescence of clinical signs was also observed, with no significant differences on both groups. It was concluded that both subtypes BHV-1.1 and BHV-1.2a were able to induce clinically undistinguishable respiratory disease in calves, either subsequent to a primary infection or following reactivation.

Is there an association between T102C polymorphism of the serotonin receptor 2A gene and urinary incontinence?

The regulation of bladder function is influenced by central serotonergic modulation. Several genetic polymorphisms related to serotonin control have been described in the literature. T102C polymorphism of the serotonin receptor 2A gene (5-HT2A) has been shown to be associated with certain diseases such as non-fatal acute myocardial infarction, essential hypertension, and alcoholism. In the present study, we examined the association between 5-HT2A gene polymorphism and urinary incontinence in the elderly. A case-control study was performed in 298 elderly community dwellers enrolled in the Gravataí-GENESIS Project, Brazil, which studies gene-environmental interactions in aging and age-related diseases. Clinical, physical, biochemical, and molecular analyses were performed on volunteers. 5-HT2A genotyping was determined by PCR-RFLP techniques using the HpaII restriction enzyme. The subjects had a mean age of 68.05 ± 6.35 years (60-100 years), with 16.9% males and 83.1% females. The C allele frequency was 0.494 and the T allele frequency was 0.506. The CC genotype frequency was 21.78%, the CT genotype frequency was 55.24% and the TT genotype frequency was 22.98%. We found an independent significant association between the TT genotype (35.7%) and urinary incontinence (OR = 2.06, 95%CI = 1.16-3.65). Additionally, urinary incontinence was associated with functional dependence and systolic hypertension. The results suggest a possible genetic influence on urinary incontinence involving the serotonergic pathway. Further investigations including urodynamic evaluation will be performed to better explain our findings.

The polymorphism of the serotonin-2A receptor T102C is associated with age

Epidemiological investigations suggest that T102C polymorphism of gene 5-HT2A may be associated with mean life span because diseases and behaviors related to this polymorphism, such as schizophrenia, suicide, aggression, and addiction, may potentially shorten mean life span. A sample of 687 individuals without previous neuropsychiatric disease was genotyped and separated into 3 groups according to their gender and age: 14-45 years old, 46-64 years old and 65-100 years old. Molecular genotyping was performed using the technique of polymerase chain reaction followed by restriction fragment length polymorphism using HpaII restriction enzyme. 5-HT2A genotype frequencies were: TT = 21.5% (148), CC = 16.6% (114) and TC = 61.9% (425) and allele frequencies were T = 52.5% and C = 46.5%. Significant differences were found between mean age of the TT genotype carriers (60.27 ± 12.60 years) and TC genotype carriers (56.80 ± 13.18 years) of T102C polymorphism of gene 5-HT2A (P = 0.026) as well as the age groups (P = 0.012). Carriers of genotype TT were older than the other two genotypes, whereas carriers of genotype CC had an intermediate age compared with TT and CC subjects. The present results demonstrate an association between T102C polymorphism of gene 5-HT2A and age. Our results suggest that T102C polymorphism of gene 5-HT2A is associated with mean life span, and thus this gene becomes a possible candidate for the group of adaptive genes to meat consumption proposed in the literature. Further studies should be conducted in order to elucidate this association.
