Abstract

Aim: Our objective in conducting this study was to estimate the presence of lymphatic, blood vessel and neural invasion on Hematoxylin & Eosin (H&E) staining and also, the microvessel density detected by immunohistochemistry (MVD), in gastric adenocarcinoma, as well as their relationship with the clinical, pathological and biological characteristics of the tumors. Materials and Methods: To assess the vascular and neural invasion in our study, we included 367 patients diagnosed with gastric cancer. For the immunohistochemical study of MVD, from all cases with gastric carcinoma, we selected 28 patients, 12 patients with gastric biopsy and 16 patients with total gastric resection, which established the TNM stage. All the gastric biopsies and surgical samples were prepared using the paraffin-embedding method and H&E staining and using anti-CD31 and anti-CD34 antibodies for the assessment of intratumoral MVD. Results: The positive blood vessel invasion was associated in a significant way with advanced stages (p <0.01) and high grade carcinomas (p<0.01), while lymphatic invasion was very significant associated only with advanced stage tumors (p < 0.001). Regarding peri- and intraneural invasion, there was a significant matching with the female gender (p < 0.05), advanced stages of disease (p < 0.001), the diffuse type of gastric carcinoma (p <0.05), and with poorly differentiated tumors (p<0.05). There was a close relationship between CD34 MVD and the diffuse type of gastric carcinomas, according to Lauren’s classification (p<0.05), and poorly differentiated tumors (p<0.05). The CD34 MVD values mean was significant correlated with TNM stage, especially III and IV stages (p<0.01). Conclusions: Blood vessel invasion, neural invasion and CD34 MVD play a significant role in tumors biological behavior and they can be used as important prognostic parameters which describes the aggressiveness of gastric carcinomas.

Abstract

The multicenter ENDOBACT study aimed at implementing molecular methods for identification of bacterial species encountered in infective endocarditis, and at attempting to reduce the number of cases with unknown etiology. For eighty seven cases was established a diagnosis of definite infective endocarditis. Thirty two of these cases had negative blood cultures. For nine cases out of 32, valve pieces were available and an attempt was made to identify the etiological agent by molecular techniques. Thirty seven available isolates were identified by phenotypical and molecular comparative methods: 16S rRNA (all available isolates), rpoB (staphylococci, streptococci and enterococci), sodA (streptococci and enterococci) genes sequencing. For eight isolates, the comparative results were discrepant. Species identification of one coagulase negative staphylococcal strain was assigned using molecular methods. Molecular identification methods applied here might represent an added value for clinical and conventional microbiological diagnosis of infective endocarditis in Romania.

Abstract

Introduction: Multidrug-resistant tuberculosis (MDR-TB) represents an important public health problem. Rapid molecular methods detect the mutations responsible for drug- resistance and can shorten the time required for diagnosis and initiation of appropriate therapy. The objectives of our study were to optimize a multiplex allele-specific PCR technique (MAS-PCR) to detect rpoB mutations and to specify the type and frequency of these mutations. Material and methods: We have tested 47 non-duplicate MDR-TB, including extensively drugresistant tuberculosis (XDR-TB) strains, identified during 2007-2012, using MAS-PCR for detection of mutations in rpoB codons 531, 526 and 516. Results: The most common mutation was located in codon 531 (63.82%), while only 12.76% and 10.63% of the strains showed mutations in codon 516 and 526, respectively; for six strains we have not identified mutation in the targeted codons. Conclusion: MAS-PCR revealed the mutations prevalent in our region, with good sensitivity (87.2%), suggesting the usefulness of this test in the rapid diagnosis of MDR-TB

Abstract

Background: Shared decision making (SDM) is becoming more and more important for the patient-physician interaction. There has not been a study in Romania evaluating patients’ point of view in the SDM process yet. Therefore, the present study aims to evaluate the psychometric parameters of the translated Romanian version of SDM-Q-9.

Material and methods: A multicentric cross-sectional study was performed comprising eight recruitment centers. The sample consisted of in- and outpatients who referred to Hospital Units for treatment for atrial fibrillation or collagen diseases. Furthermore, patients who were members of Autoimmune Disease Patient Society were able to participate via an online survey. All participants completed the Romanian translated SDM-Q-9.

Results: Altogether, 665 questionnaires were filled in within the hospital setting (n = 324; 48.7%) and online (n= 341; 51.3%). The Romanian version had good internal consistency (Cronbach α coefficient of 0.96.) Corrected item correlations were good ranging from 0.64 to 0.89 with low corrected item correlations for item 1 and item 7. PCA found a one-factorial solution (similar with previous reports) but the first item had the lowest loading.

Conclusion: SDM-Q-9 is a useful tool for evaluation and improvement in health care that was validated in Romania and can be used in clinical setting in this country.
