Abstract

Adenylat kinase is an ubiquitous enzyme found in prokaryotes and eukaryotes. In the present study we examined the inhibition of Streptococcus pneumoniae adenylate kinase (AKSP) by six 5-arylidene-thiazolidin-4- on-2-thione derivates using 2, 4-dinitrophenylhydrazine colorimetric assay. Inhibition of AKSP activity with synthetic compounds was performed against recombinant enzyme over-expressed in E. coli. The compound C10H6BrNOS2 with the bromine atom in -ortho position has shown the most efficient inhibitory activity; I50 value (the inhibitor concentration that leads to 50% activity inhibition) was 0.067mM.

Abstract

The purpose of this paper was to compare the composition (weight % of total identified FA) in saturated (SFA), monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids from 3 food matrices (sunflower oil, palm oil and lard) by 2 different techniques, gas chromatography - mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR). For GC-MS technique, fatty acid methyl esters (FAMEs) identification in the samples was performed by comparison of the retention times (RT) and the mass/charge (m/z) ratio characteristic of each FAME component in the reference standards used (F.A.M.E. Mix C4 - C24 and SRM®2377). FAMEs quantification from food samples was realized by applying correction factors calculated based on reference standards. NMR spectra were recorded on a Bruker Advance 400 MHz spectrometer, operating at 9.4 Tesla corresponding to the resonance frequency of 400.13 MHz for the 1H nucleus. The NMR spectra was recorded directly on the oil without any sample preparation. The difference between the mean values of the fatty acids content determined by GC-MS and NMR was not more than ± 15% for sunflower oil and lard, and ± 6% for palm oil.

Abstract

Chronic myelomonocytic leukemia (CMML) is a clonal hematopoietic stem cell disorder that is characterized by the presence of an absolute monocytosis (1 × 10^ 9/l) in the peripheral blood, the overlap of myelodisplastic aspects and myeloproliferative aspects in the bone marrow and tendency to transform into acute myeloid leukemia. CMML is considered to be the most aggressive chronic myeloid leukemia. We present the case of a 48 years old woman who was hospitalized in March 2013 in the Center of Hematology and Bone Marrow Transplantation for anemia related symptoms. Initial investigations showed anemia, relative monocytosis (10% monocytes of the WBC differential) with an increasing absolute number of monocytes (> 1,000/μl) in the following months. Initial exploration of the bone marrow (aspirate and bone marrow biopsy and immunohistochemistry IHC tests) revealed elements of trilinear dysplasia and an increased percentage of myeloblasts (11-14%). In the next four months myeloblasts percentage remained below 20% (8-14%) and it has been observed a gradually increasing of monocytoid elements (> 20%). Immunophenotyping in the bone marrow aspirate identified a monocytic proliferation with high percentage (8%) of immature cells. The karyotype reported the presence of clones with t (1;3). Initially diagnosed as RAEB-2 (WHO) the case was recomitted in CMML-type 2 with a progression to acute myeloid leukemia (AML). Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has been performed after getting the best possible therapeutic response with AML chemotherapy type (complete remission). Allo-HSCT was performed using myeloablative conditioning, 12 months after diagnosis. The patient is now in complete remission, 24 months after allo-HSCT.

Abstract

In the 2016 revision of the World Health Organization classification the term therapy-related myeloid neoplasia (t-MN) defines a subgroup of acute myeloid leukemia (AML) comprising patients who develop myelodysplastic syndrome (MDS-t) or acute myeloid leukemia (AML-t) after treatment with cytotoxic and/or radiation therapy for various malignancies or autoimmune disorders. We report the case of a 36 year old patient with t-MN (t-MDS) after achieving complete remission (CR) of a PML-RARA positive acute promyelocytic leukemia (APL) at 32 months after diagnosis. Initially classified as low risk APL and treated according to the AIDA protocol - induction and 3 consolidation cycles - the patient achieved a complete molecular response in September 2013 and started maintenance therapy. On follow-up PML-RARA transcript remained negative. In January 2016 leukopenia and thrombocytopenia developed and a peripheral blood smear revealed hypogranular and agranular neutrophils. Immunophenotyping in the bone marrow aspirate identified undifferentiated blast cells that did not express cytoplasmic myeloperoxidase. The cytogenetic study showed normal karyotype. The molecular biology tests not identified PMLRARA transcript. A diagnosis of t-MDS (AREB-2 - WHO 2008) was established. Treatment of AML was started with 2 “3+7” regimens and 1 MEC cycle. Two months from diagnosis, while in CR, an allogeneic HSCT from an unrelated HLA compatible donor was performed after myeloablative regimen. An unfavorable clinical evolution was followed by death on day 9 after transplantation. The occurrence of t-MNs during CR of APL represents a particular problem in terms of follow-up and differential diagnosis of relapse and constitutes a dramatic complication for a disease with a favorable prognosis.

Abstract

Background & Aims. Considering the ability of anti-TNF alpha drugs to lower the burden intestinal inflammation in patients with inflammatory bowel disease (IBD), and the similarity between IBD and ankylosing spondylitis (AS) regarding inflammatory intestinal involvement, we aimed to investigate the impact of anti-TNF alpha biologic therapy on subclinical intestinal inflammation in AS patients.

Methods. Between January 2008 and December 2013, 38 AS patients and 23 controls were enrolled in the study and investigated with small bowel videocapsule endoscopy examination and ileocolonoscopy. Each tertile of the small bowel (proximal, mid and distal) was assessed by calculating the Lewis score based on the image stream.

Results. The Lewis scores were significantly higher in the AS group compared to controls (580.9 ± 818 vs. 81 ± 121, p<0.001). 16 patients (42.1%) were on anti-TNF alpha therapy (Adalimumab (n = 5), Infliximab (n = 5) or Etanercept (n = 6)).31.3% of them used NSAIDs simultaneously, compared with 77.3% of the other patients (p<0.01). Their Lewis scores were lower compared to the other patients for the entire small bowel (306 ± 164 vs. 790 ± 1038, p = 0.015), its proximal and distal tertiles (238 ± 154 vs. 560 ± 543, p = 0.021, and 140 ± 189 vs. 300 ± 220, p = 0.027, respectively). The Lewis score was also lower in patients receiving Adalimumab/Infliximab compared to those on Etanercept for the entire bowel and its distal tertile (262 ± 165 vs. 380 ± 148, p = 0.069 and 62 ± 101 vs. 273 ± 236, p = 0.060, respectively).

Conclusion. Anti-TNF alpha therapy in patients with AS reduces the subclinical intestinal inflammation, but the magnitude seems to depend upon the class anti-TNF alpha agent used (Clinical Trials. gov NCT00768950).

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.

Abstract

Introduction. Hypertrophic cardiomyopathy (HCM) is a disease with increased left ventricular (LV) wall thickness not solely explained by abnormal loading conditions, with great heterogeneity regarding clinical expression and prognosis. The aim of the present study was to collect data on HCM patients from different centres across the country, in order to assess the general characteristics and therapeutic choices in this population.

Methods. Between December 2014 and April 2017, 210 patients from 11 Romanian Cardiology centres were enrolled in the National Registry of HCM. All patients had to fulfil the diagnosis criteria for HCM according to the European Society of Cardiology guidelines. Clinical, electrocardiographic, imaging and therapeutic characteristics were included in a predesigned online file.

Results. Median age at enrolment was 55 ± 15 years with male predominance (60%). 43.6% of the patients had obstructive HCM, 50% non-obstructive HCM, while 6.4% had an apical pattern. Maximal wall thickness was 20.3 ± 4.8 mm (limits 15-37 mm) while LV ejection fraction was 60 ± 8%. Heart failure symptoms dominated the clinical picture, mainly NYHA functional class II (51.4%). Most frequent arrhythmias were atrial fibrillation (28.1%) and non-sustained ventricular tachycardia (19.9%). Mean sudden cardiac death risk score (SCD-RS) was 3.0 ± 2.3%, with 10.4% of the patients with high risk of SCD. However, only 5.7% received an ICD. Patients were mainly treated with beta-blockers (72.9%), diuretics (28.1%) and oral anticoagulants (28.6%). Invasive treatment of LVOT obstruction was performed in a small number of patients: 22 received myomectomy and 13 septal ablation. Cardiac magnetic resonance was reported in only 14 patients (6.6%).

Conclusions. The Romanian registry of HCM illustrates patient characteristics at a national level as well as the gaps in management which need improvement – accessibility to high-end diagnostic tests and invasive methods of treatment.
