In the pharmacokinetic analysis of ethanol after oral administration, only single- or two-compartment models are used, but their precision in estimating pharmacokinetic parameters might be insufficient. In a recent study, pharmacokinetic analysis using a modified Norberg three-compartment model was performed after oral administration of differently sweetened alcoholic solutions and compared to pharmacokinetic analysis using the classic Widmark model. On three occasions, eight male volunteers consumed differently sweetened alcoholic solutions: non-sweetened, sweetened with sucrose, and sweetened with steviol glycoside. Blood ethanol concentration was determined from samples obtained at t = 15, 30, 60, 90, 120, 180 min after consumption. Pharmacokinetic analysis was performed model independently, using the classic Widmarks model and using the modified Norberg model. Results showed that estimated pharmacokinetic parameters depend on the type of model used. The classic Widmark model in particular overestimated the fraction of absorbed ethanol from the gastrointestinal system to systemic circulation. Furthermore, the type of sweetener also affected pharmacokinetic parameters, although the difference was not statistically significant. In conclusion, the novel pharmacokinetic model, while being more physiological, fits experimental data better and hence is more suitable for modelling real-life alcohol consumption. In addition, the effect of natural non-caloric sweetener steviol glycoside on ethanol pharmacokinetics, analysed for the first time in the current research, might be different when compared to the common-used sweetener sucrose.

We report a case of a 39-year old male patient who presented to us with several months of lower back pain. Following clinical assessment, the patient underwent a magnetic resonance imaging exam, which after using advanced imaging protocols showed a ventrolateral disc hernation toward the psoas muscle. Based upon the findings in the magnetic resonance and the electromyoneurographic examination, the decision was made to treat the patient conservatively. Coronal planes are useful for discerning changes of various origins not usually seen on the sagital and axial planes. If needed, additional advanced protocol is available for increased specificity and diagnostic accuracy.

Background and Objectives: Functional status of the mother after delivery is crucial for performing activities of daily living and caring for the newborn. It is important to assess functional abilities after childbirth in order to improve the quality of postpartum care. The aim of this study is to determine the psychometric properties of the questionnaire and assess the functional abilities after childbirth. Materials and Methods: This study is observational. Postpartum Functional Assessment Questionnaire includes eleven items. 301 women after childbirth, 234 after vaginal birth and 67 after caesarean section participated in the study. An assessment of pain intensity and functional abilities was performed on the first and third day after childbirth. The Factor and Cronbach’s alpha analyses were performed to determine the factor structure and internal consistency. Results: The analysis reveals two factors, with seven items loading on factor 1 and four on factor 2. Cronbach’s alpha for construct I (Mobility) at the first day was 0.927 and at the third day was 0.913; and for Factor II (Self-care) at the first day was 0.846 and at the third day was 0.894. All between-group differences in pain intensity and functional abilities were highly statistically significant (p < 0.001). Differences between the first and third postpartum day were statistically significant for all variables and all subgroups (p < 0.001). Conclusions: Postpartum Functional Assessment Questionnaire has good psychometric properties and is a valuable tool for use in clinical practice.

Mirror syndrome is a rare condition of generalized maternal oedema caused by fetal hydrops. A 37-year-old patient was admitted to our hospital because of suspected mirror syndrome caused by fetal cardiomyopathy. At 26th week of gestation patient developed bilateral pulmonary oedema as her condition rapidly deteriorated. Consequently, preterm labor was induced, percutaneous evacuation of fetal ascites was performed, and the patient finally vaginally delivered stillborn fetus. Although the initial postpartum period was severely complicated by hemorrhage, the condition of the patient significantly improved later, and she was discharged seven days after delivery. We believe this case is worth presenting due to its rarity and significant perinatal and obstetric challenges in treatment of those patients. Furthermore, preimplantation genetic testing could be performed to prevent at least some of the cases.

Objective: This study aimed to examine the associations between dietary consumption patterns, physical activity level, and body composition among students of biomedical sciences, and to determine whether dietary consumption patterns and body composition differed according to physical activity level. Methods: A cross-sectional study involved 187 ungraduated university students. The study was conducted among undergraduate physiotherapy students at University North, Varaždin, Croatia, with all measurements performed in the Physiotherapy Laboratory of the Department of Physiotherapy. Assessment of body composition was carried out using Body Composition Analyzer Tanita MC 780, nutritional status using the Food Frequency Questionnaire, and the physical activity using the International Physical Activity Questionnaire-long version. Results: The frequency of consumption of each category of food did not significantly differ between participants, with low, moderate and high levels of physical activity. Weak positive correlations were observed between the frequency of milk and milk product consumption and muscle mass (r = 0.153), and between sugar consumption and body fat (r = 0.189). No statistically significant differences were observed in dietary consumption patterns across physical activity levels or in body composition across physical activity groups. Conclusions: The findings provide descriptive information on dietary patterns, physical activity, and body composition among biomedical sciences students and may help identify areas for future health-promotion interventions and comparative studies in university populations.
