Trends in Coronary Artery Anomalies Detection by Coronary Computed Tomography Angiography (CCTA): A Real-Life Comparative Study before and during the COVID-19 Pandemic.

Background: In the wake of the coronavirus disease 19 (COVID-19) pandemic, affecting healthcare systems globally, urgent research is needed to understand its potential repercussions on the diagnosis and management of cardiovascular disorders. This emphasises the importance of detecting coronary artery anomalies (CAAs), rare conditions that can range from benign to potentially life-threatening manifestations. We aimed to retrospectively assess the impact of the COVID-19 pandemic on the detection of various coronary anomalies using Coronary Computed Tomography Angiography (CCTA) within a regional tertiary cardiology unit in north-eastern Romania, focusing on perceived occurrence in the population under study, types, and related demographic and clinical factors.

An Innovative Non-Invasive Method for Early Detection and Monitoring of Acute Compartment Syndrome.

Acute compartment syndrome is a major surgical emergency with complex pathophysiology and a highly unpredictable pattern of evolution. We hypothesized that the onset of acute compartment syndrome of the leg or forearm is associated with variations in the surface temperature of the distal segment (foot or hand) with a distinct pattern, which acts as an early warning sign. We developed a monitoring device that consists of two thermic sensors attached to a modular limb splint, which continuously measure the temperature difference between the proximal and distal regions of the limb (i.

Casting Light on The Hidden Prevalence: A Novel Perspective on Hypoplastic Coronary Artery Disease.

Coronary artery anomalies (CAAs) represent a group of rare cardiac abnormalities with an incidence of up to 1.2%. The aim of this retrospective study was to conduct a comprehensive epidemiological assessment of the prevalence of hypoplastic coronary arteries using coronary computed tomography angiography (CCTA) in patients with diagnosed CAAs and individuals presenting with cardiovascular manifestations in the north-eastern region of Romania.

The Implications of Cytochrome P450 2D6/CYP2D6 Polymorphism in the Therapeutic Response of Atypical Antipsychotics in Adolescents with Psychosis-A Prospective Study.

Exploring the Role of Biomarkers Associated with Alveolar Damage and Dysfunction in Idiopathic Pulmonary Fibrosis-A Systematic Review.

Background: Idiopathic pulmonary fibrosis (IPF) is one of the most aggressive forms of interstitial lung diseases (ILDs), marked by an ongoing, chronic fibrotic process within the lung tissue. IPF leads to an irreversible deterioration of lung function, ultimately resulting in an increased mortality rate. Therefore, the focus has shifted towards the biomarkers that might contribute to the early diagnosis, risk assessment, prognosis, and tracking of the treatment progress, including those associated with epithelial injury.

Role of Chemerin and Perivascular Adipose Tissue Characteristics on Cardiovascular Risk Assessment by Arterial Stiffness Markers in Patients with Morbid Obesity.

Background And Objective: The development of arterial stiffness (AS) in obesity is a multifactorial and complex process. The pleomorphic actions of adipokines and their local activity in perivascular adipose tissue (PVAT) are potential modulators of AS appearance and progression. We aimed to assess the correlations between two adipokines (chemerin, adiponectin), PVAT morphological changes (adipocyte size, blood vessel wall thickness) and AS parameters in the special subgroup of patients with morbid obesity.

Determinants of Arterial Stiffness in Patients with Morbid Obesity. The Role of Echocardiography and Carotid Ultrasound Imaging.

Morbid obesity is accompanied by an increased cardiovascular (CV) risk, which justifies a multidisciplinary, integrative approach. Arterial stiffness has a well-defined additional role in refining individual CV risk. Given that echocardiography and carotid ultrasound are usual methods for CV risk characterization, we aimed to identify the imaging parameters with a predictive value for early-onset arterial stiffness.

Experimentally Induced Burns in Rats Treated with Innovative Polymeric Films Type Therapies.

Considering that microbial resistance to antibiotics is becoming an increasingly widespread problem, burn management, which usually includes the use of topical antimicrobial dressings, is still facing difficulties regarding their efficiency to ensure rapid healing. In this context, the main objective of this research is to include new oxytetracycline derivatives in polymeric-film-type dressings for the treatment of wounds caused by experimentally induced burns in rats. The structural and physico-chemical properties of synthesized oxytetracycline derivatives and the corresponding membranes were analyzed by FT-IR and MS spectroscopy, swelling ability and biodegradation capacity.

Efficacy of Therapeutic Plasma Exchange in Severe Acute Respiratory Distress Syndrome in COVID-19 Patients from the Western Part of Romania.

Background and Objectives: The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has surprised the medical world with its devastating effects such as severe acute respiratory distress syndrome (ARDS) and cytokine storm, but also with the scant therapeutic solutions which have proven to be effective against the disease. Therapeutic plasma exchange (TPE) has been proposed from the very beginning as a possible adjuvant treatment in severe cases. Our objective was to analyze the evolution of specific biological markers of the COVID-19 disease before and one day after a therapeutic plasma exchange session, how a change in these parameters influences the patient’s respiratory status, as well as the impact of TPE on the survival rate.

Chitosan Microparticles Loaded with New Non-Cytotoxic Isoniazid Derivatives for the Treatment of Tuberculosis: In Vitro and In Vivo Studies.

Lately, in the world of medicine, the use of polymers for the development of innovative therapies seems to be a major concern among researchers. In our case, as a continuation of the research that has been developed so far regarding obtaining new isoniazid (INH) derivatives for tuberculosis treatment, this work aimed to test the ability of the encapsulation method to reduce the toxicity of the drug, isoniazid and its new derivatives. To achieve this goal, the following methods were applied: a structural confirmation of isoniazid derivatives using LC-HRMS/MS; the obtaining of microparticles based on polymeric support; the determination of their loading and biodegradation capacities; in vitro biocompatibility using MTT cell viability assays; and, last but not least, in vivo toxicological screening for the determination of chronic toxicity in laboratory mice, including the performance of a histopathological study and testing for liver enzymes.

Large giant cell tumor of the posterior iliac bone - an atypical location. A case report and literature review.

Giant cell tumor (GCT) is a locally aggressive tumor but with benignity features, representing approximately 18% of non-malignant bone tumors in European countries, with slight female predominance. Malignancy in GCT is rare, about <2% of cases and is more common at older ages. Is known that usually occurs at the epiphyses of long bones, but extremely rare may have another location, such as the pelvic bone.

Designing of Chitosan Derivatives Nanoparticles with Antiangiogenic Effect for Cancer Therapy.

Angiogenesis is a physiological process involving the growth of new blood vessels, which provides oxygen and required nutrients for the development of various pathological conditions. In a tumor microenvironment, this process upregulates the growth and proliferation of tumor cells, thus any stage of angiogenesis can be a potential target for cancer therapies. In the present study, chitosan and his derivatives have been used to design novel polymer-based nanoparticles.

Morphometric characteristics of fibrocartilaginous tissue in the herniated intervertebral disc.

The purpose of this research was to identify a possible correlation between the morphometric characteristics of fibrocartilaginous tissue in the intervertebral herniated disc fragment and the clinical and imagistic characteristics of patients with back pain. Sixty-two samples were included in this study. Intervertebral herniated disc fragments obtained during surgery (microdiscectomy) were analyzed histologically and morphologically.

Clinical relevance and accuracy of p63 and TTF-1 for better approach of small cell lung carcinoma versus poorly differentiated nonkeratinizing squamous cell carcinoma.

Lung cancer high mortality rate remains a major problem, despite the actual progress in its early detection and therapeutic design. Since lung cancer' treatment requires separation of tumors in small cell carcinoma and non-small cell carcinoma, the histopathological diagnosis focuses on this basic distinction, while immunohistochemistry contributes considerably to confirm the diagnosis accuracy. In order to check the assumption that p63 is a useful marker for squamous cellular differentiation, we used two antibodies: anti-p63 and anti-thyroid transcription factor-1 (TTF-1), based on their immunoexpression to differentiate small cell lung carcinoma (SCLC) from poorly differentiated nonkeratinizing squamous cell carcinoma (SCC).

The role of immunohistochemistry in the diagnosis and management of synovial sarcoma.

Synovial sarcoma (SS) is a malignant soft tissue tumor representing 5-10% of all soft tissue sarcomas. Most synovial sarcomas are found at the extremities, especially in the lower limbs. A 28-year-old female presented at the Department of Plastic and Reconstructive Surgery, "Dr.

Expression and significance of Ki-67 in lung cancer.

Ki-67 parameter is a proliferation marker in malignant tumors. The increased proliferation activity and the decreased prognosis in lung cancer determined us to investigate different parameters connected to the tumor's aggression, such as cellularity, Ki-67 positivity rate, and proliferating cell nuclear antigen (PCNA). We evaluated the proliferative activity in 62 primary lung tumors by determining the cell's percentage of Ki-67 and immunoreactive PCNA (using MIB-1 and PCNA monoclonal antibodies), classifying Ki-67 and PCNA immunoreactivity into three score groups.

Alveolar rhabdomyosarcoma in an adolescent male patient - case report and current perspectives.

Alveolar rhabdomyosarcoma (RMS) is a common pediatric malignant mesenchymal tumor, representing half of soft tissue sarcomas and approximately 5% of all cancers. We present the case of an adolescent male patient treated in our Department for a tumoral mass located in the middle third of the forearm. Magnetic resonance imaging (MRI) and angiography-computed tomography (angio-CT) showed a large mass located in the muscles of the anterior compartment of the forearm.

Conventional chondrosarcoma in the right hand with the invasion of the pisiform and the hamate bones - case report.

Chondrosarcoma is a malignant hyaline cartilage forming tumor. It is a rare pathology, with an estimated incidence of one in 200 000 individuals per year. It appears in two forms: primary, representing 90% of all cases and secondary emergence that develops on preexistent lesions.

Toxicity, Biocompatibility, pH-Responsiveness and Methotrexate Release from PVA/Hyaluronic Acid Cryogels for Psoriasis Therapy.

Poly(vinyl alcohol)/hyaluronic acid cryogels loaded with methotrexate were studied. The physical⁻chemical characterization of cryogels was performed by FT-IR spectroscopy, scanning electron microscopy, differential scanning calorimetry and dynamic mechanical thermal analysis. Acute toxicity and haematological parameters were determined by "in vivo" tests.

Expression of E-cadherin in lung carcinoma, other than those with small cells (NSCLC).

It was suggested that the decrease and/or loss of E-cadherin expression in non-small cell lung cancer (NSCLC) is responsible for the development of the malignant phenotype. Moreover, clinical studies showed that the reduced expression of E-cadherin is associated with tumoral differentiation, with the presence of lymph node metastasis and with unfavorable diagnosis of patients with NSCLC. In order to evaluate if E-cadherin expression is involved in the NSCLC pathogenesis and significantly associated with clinicopathological parameters, we investigated the immunohistochemical (IHC) expression of E-cadherin in 47 lung carcinomas with tumoral resection pieces in the control peritumoral lung tissue, looking for possible correlations between the expression of this molecule and the clinicomorphological features and the evolutive prognosis of the patients.
