Real-World Data with CDK4/6 Inhibitors-A Single Center Experience from Croatia.

Background: There are limited real-world data (RWD) regarding the use of cyclin-dependent kinase (CDK) 4/6 inhibitors in western Balkan. The aim of our study was thus to analyze factors influencing progression-free survival (PFS) and overall survival (OS), along with the differences in adverse effects of CDK 4/6 therapy in a tertiary healthcare center in Croatia.

Methods: We evaluated medical and demographic data for 163 consecutive patients with metastatic breast cancer treated with CDK4/6 inhibitors for at least one month, from October 2018, after the drug became available in Croatia.

Clinical significance of possible HLA biomarkers in axial spondyloarthritis beyond HLA-B27 positivity.

The aim of this study is to compare four forms of axial spondyloarthritis (axSpA): non-radiographic axial spondyloarthritis (nr-axSpA), ankylosing spondylitis (AS), non-radiographic axial psoriatic arthritis (nr-axPsA) and radiographic axial psoriatic arthritis (r-axPsA). In a cross-sectional retrospective study, gender difference, human leukocyte antigen (HLA) typing, laboratory C-reactive protein (CRP) and erythrocyte sedimentation (SE) values, and radiographic and magnetic resonance scans were analyzed. One hundred and thirty-seven patients were included in the study: 45 AS, 51 nr-axSpA, 32 r-axPsA and 9 nr-axPsA; 74 women and 63 men.

GLUT1 Deficiency Syndrome-Early Treatment Maintains Cognitive Development? (Literature Review and Case Report).

Glucose transporter type 1 (GLUT1) is the most important energy carrier of the brain across the blood-brain barrier, and a genetic defect of GLUT1 is known as GLUT1 deficiency syndrome (GLUT1DS). It is characterized by early infantile seizures, developmental delay, microcephaly, ataxia, and various paroxysmal neurological phenomena. In most cases, GLUT1DS is caused by heterozygous single-nucleotide variants (SNVs) in the gene that provoke complete or severe impairment of the functionality and/or expression of GLUT1 in the brain.

A novel VARS2 gene variant in a patient with epileptic encephalopathy.

Mitochondrial disorders are heterogeneous clinical syndromes caused by defective activity in the mitochondrial respiratory chain, resulting in a faulty oxidative phosphorylation system. These inherited disorders are individually rare, and furthermore they are phenotypic variables. The genetically characterized mitochondrial disorders are rarely associated with epileptic encephalopathies.

Multiple Myeloma Index for Risk of Infection.

Based on our earlier research into the main characteristics and risk factors for infections in hospitalized patients with multiple myeloma, we created the numerical Multiple Myeloma Index for Risk of Infection (MMIRI) to predict infection in myeloma patients. The included factors that could influence the pathogenesis and incidence of infections were sex, performance status, Durie Salmon stage of disease, International Staging System, serum creatinine level, immune paresis, neutropenia, serum ferritin level, the presence of any catheters, disease duration, stable/progressive disease, and type of therapy. For each of these parameters, the strength of association with infection was statistically estimated and specific number of points was assigned to each of these parameters, proportional to the strength of the association.

The effectiveness of a 40-year long iodine prophylaxis in endemic goitre region of Grobnik, Croatia.

The region of Grobnik, in the north west of Croatia, 15 km away from the Adriatic coast and 400 meters above the sea level, used to be known as a centre of endemic goitre. Iodine prophylaxis of 10 mg KJ added per kilo salt started in Croatia during the year 1953 and it was increased to 25 mg KJ per kilo in 1996. During 1961, the prevalence of goitre among Grobnik school children was 63%, while in the adult population it was 34%.

Heart embolization with the Kirschner wire without cardiac tamponade.

The case of the heart embolization with the Kirschner wire that was used for shoulder trauma fixation, 2 years previously in a 67-year-old female, is reported. This case is unique; although embolization of foreign bodies to the heart is not a novel occurrence, heart embolization with non-broken Kirschner wire with a total length of 13.5 cm without cardiac tamponade was not described in medical literature so far.
