Off-label prescribing is widespread among pediatricians, and it is unlikely that this trend will soon be bound by a uniform legal framework. This is necessitated by the fact that there are four variables: the patient’s health condition, the physician’s experience and knowledge, the legislative measures (laws, directives, guidelines, and recommendations), and finally, the pharmaceutical industry. There is considerable concern worldwide about the use of off-label medicines in children. We may call it an enormous global problem that is much talked about and written about; however, we should not forget that the goal around which everyone should unite is the patient’s life. For healthcare providers, the most important thing will always be the health and preservation of the patient’s life, particularly when it comes to children with life-threatening conditions in neonatal and pediatric intensive care units (NICU and PICU). The study aimed to examine the prevalence of off-label drug use in pediatrics. Literature research was conducted, and we included studies from 2012 to 2022 that evaluated off-label drug prevalence in various pediatric patient populations.

Three-dimensional (3D) printing has emerged as a new promising technique for the production of personalized dosage forms and medical devices. Polyvinyl alcohol is prominently used as a source material to produce 3D-printed medicines via fused deposition modeling (FDM)—a technology that combines hot melt extrusion and 3D printing. A preliminary screening of three grades of PVA indicated that partially hydrolyzed PVA with a molecular weight (MW) of 31,000–50,000 and plasticized with sorbitol was most suitable for 3D printing. Paracetamol was used as a model drug. The materials and the produced filaments were characterized by X-ray powder diffraction (XRPD), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The complex viscosity (η*) of the polymer melts was determined as a function of the angular frequency (ω) at the printing temperature to assess their printability. Three-dimensional printlets with a 40% infill exhibited an immediate release of the API, while tablets with a higher infill were prone to a prolonged release regardless of the filament drug loading. A factorial design was used to give more insight into the influence of the drug-loading of the filaments and the tablet infill as independent variables on the production of 3D printlets. The Pareto chart confirmed that the infill had a statistically significant effect on the dissolution rate after 45 min, which was chosen as the response variable.

The objective of the study was to compare three different questionnaires (Short Form (SF)-6D, EuroQuol (EQ)-5D and WHO-5) to establish which one is more sensitive and which one gives an adequate assessment of the quality of life in patients with diabetes.

The prevalence of obesity is increasing rapidly. The latest World Health Organization – WHO report declares the disease as an epidemic. After pharmacodynamic, pharmacokinetic, clinical and pharmacoepidemiologic data analysis and comparison of the three classes of antidiabetic medicinal products: GLP-1 receptor agonists, DPP-4 inhibitors and SGLT2 inhibitors, a literature review of the topic, patient education and the concept of pharmaceutical care emerged as methods for dealing with the most common adverse drug reactions, safety concerns, and drug interactions.

The objective of this issue is to assess the effectiveness of an educational program on patients with gestational diabetes mellitus (GDM). The study design is a case-control study that includes30 pregnant women, mild GDM; between 19 and 41 years of age, without severe complications of diabetes. The women were divided into two groups – passing education Group I (n=15), and Group II (n=15), not passing education. A 1-month education was conducted. The clinical data and metabolic control for the two groups were evaluated. Group ІI shows better improvement in comparison with Group I, and also mild improvement in the blood glucose level. The patients’ quality of life improves with about 1.0 point at average according to the applied questionnaire. This is the first time that the education is being done by pharmacists to patients with GDM at pharmacy conditions. The results prove that the educational approach has the potential to improve patient’s quality of life. Key words: Gestational diabetes mellitus, education, pharmaceutical care.
