ABSTRACT

Background and Objectives: Despite advances in surgical techniques, industry adjuncts, and cerebral perfusion techniques, the in-hospital mortality rate of type A acute dissection (TAAD) remains at 15-30%. This study aimed to investigate the influence of different extents of aortic resection on survival and quality of life (QoL) after long-term follow-up. Materials and Methods: A retrospective observational trial was performed, including 165 patients operated upon for TAAD. Patients were divided into two groups according to the extent of their aortic repair: the first group comprised patients who had ascending aorta replacement and the second included patients who had hemiarch or total arch replacement. The groups were compared with regard to their baseline characteristics, operative characteristics, survival, complications, and QoL during nine years of follow-up. Results: The mean follow-up time was 75.6 months (1-108 months). The mean survival in the ascending aorta repair group was 89.651 (81.242-98.061) months and was 54.801 (40.053-69.548) months in the hemiarch and arch group; the difference between the groups was significant (log-rank p < 0.001). The rate of new postoperative neurological deficits was statistically higher in the hemiarch and arch group (17.5% vs. 8.4%, p = 0.045), the most common being stroke, and was also more frequent in the hemiarch and arch group than in the ascending aorta group (with statistical significance (15.7% vs. 6.5%)). The mean SF-12 physical score from the QoL questionnaire was higher in the ascending aorta replacement group than in the hemiarch and arch group (50.1 ± 7.3 vs. 44.0 ± 11.9, p = 0.017). Additionally, the mean SF-12 mental score was higher in the ascending aorta replacement group (52.3 ± 7.3 vs. 47.1 ± 12.8, p = 0.032). Conclusions: A more aggressive approach involving aortic arch repair means a lower survival rate and lesser quality of life after long-term follow-up in comparison with the replacement of the ascending aorta. If clinically applicable, a more defensive strategy may be considered.

ABSTRACT

INTRODUCTION: Determination of RhD variants in blood donors, pregnant women, and newborns is important for transfusion strategies, in order to prevent RhD alloimmunisation and hemolytic disease of fetuses and newborns. Implementation of molecular RHD typing in two transfusion institutes is presented in this article, from Banja Luka (Bosnia and Herzegovina) and Belgrade (Serbia). STUDY DESIGN AND METHODS: Blood donors' RhD was checked by direct agglutination assays (tube) and indirect antiglobulin test (gel). Molecular RHD typing was performed by PCR-SSP with fluorometric signal detection in both centres. Donors were selected by weak RhD serological reactivity (Banja Luka, 85 samples; Belgrade, 62 samples) or serologically RhD-negative C/E-positive results (Banja Luka, 92 samples; Belgrade, 61 samples). RESULTS: Among serologically determined weak D donors from the institute from Banja Luka, weak D type 3 was the most frequent (58.8%), followed by type 1 (35.3%) and DNB (1.2%), whereas results obtained at the Belgrade institute were distributed between weak D type 1 (41.9%), type 3 (30.7%), type 14 (6.5%), type 15 (1.6%), and DNB with anti-D (1.6%). In 17.7% of serologically typed weak D samples from the Belgrade institute, the molecular typing result was standard D. Additionally, RHD presence was detected in 9.8% of serologically RhD-negative, C/E-positive samples from both institutes. CONCLUSION: Rh molecular testing was successfully implemented in both blood transfusion institutes in Banja Luka and Belgrade. This study proved the efficiency of serological algorithms for weak D, as well as the presence of the RHD gene among serologically tested RhD-negative, C/E-positive samples.

ABSTRACT

Tryptophan hydroxylase 1 (TPH1) gene, coding for serotonin synthesizing enzyme, and recent stressful life events (SLEs) have been commonly associated with suicidal behavior. TPH1 has been also hypothesized to be involved in stress-response mechanisms. The aim of this study was to assess TPH1 variant rs1800532 and its possible interaction with recent SLEs as risk factors for suicide attempt (SA) in Serbian psychiatric patients, including 165 suicide attempters and 188 suicide nonattempters. rs1800532 and recent SLEs were independently associated with SA, while rs1800532 did not moderate the effect of recent SLEs on SA vulnerability among Serbian psychiatric patients.
