Cerebral stroke is a serious worldwide health problem, as can be seen by the global epidemic of the disease. In this disorder, when the blood flow is compromised by ruptures or blocked arteries, sudden death of neurons is observed as a result of a lack of oxygen and nutrients. Numerous severe problems and frequent complications also exist in stroke patients; therefore, there is an urgent need to develop new therapeutic, diagnostic, and prognostic methods for the disease. At present, the diagnosis of stroke is based on a neurological examination, medical history, and neuroimaging, due to the fact that rapid and noninvasive diagnostic tests are unavailable. Nevertheless, oxidative stress and inflammation are considered key factors in stroke pathogenesis. Oxygen free radicals are responsible for oxidation of lipids, proteins, and DNA/RNA, which in turn contributes to oxidative damage of the brain. Toxic products of the oxidation reactions act cytostatically on the cell by damaging cell membranes and leading to neuronal death by apoptosis or necrosis. Thus, it seems that redox/inflammatory biomarkers might be used in the diagnosis of the disease. Nowadays, saliva is of increasing interest in clinical laboratory medicine. Redox biomarkers could be obtained easily, noninvasively, cheaply, and stress-free from saliva. This minireview is aimed at presenting the current knowledge concerning the use of salivary biomarkers of oxidative stress and inflammation in the diagnosis and prognosis of stroke.

Background. The infl uence of weight loss treatment on sex hormones profi le has been studied mainly in women with polycystic ovary syndrome (PCOS), but in obese premenopausal women without PCOS it still remains unclear. The aim of the study was to evaluate the eff ect of two approaches to obesity treatment on the serum level of sex hormones in obese women of child-bearing age without PCOS. Material and methods. 77 obese Caucasian women (aged 31.2 ±8.3 years) were randomized into two groups: 39 women received a low-calorie diet (LC) and 38 received an isocaloric diet plus metformin (IM), for 12 weeks. Anthropometric parameters, body composition and serum concentrations of estradiol (E2), testosterone (T), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and dehydroepiandrosterone (DHEA-S) sulfate were evaluated at baseline and after the study. Results. Reductions in body weight, body mass index (BMI), waist and body fat content with an increase in lean body percent were signifi cant and comparable between the LC and IM group after the trial. The concentrations of serum FSH, LH, E2, DHEA and T did not change in either group after treatment. A tendency towards an increase in the E2 concentration in both groups and a decrease in the T level in the LC group was observed. The correlations between a change in BMI, fat content, waist-hip ratio and a change in T were documented in the LC group. Conclusion. A 12-week low-calorie diet and an isocaloric diet combined with metformin produced comparable and signifi cant weight loss with improvements in body composition. Both interventions did not signifi cantly aff ect FSH, LH and DHEA sulfate serum concentrations, only a trend towards an E2 increase and a T decrease was observed, stronger in LC group. The signifi cant correlations shown between the changes in anthropometric and body composition parameters and T serum levels in women treated with a low-calorie diet alone show the benefi cial eff ect of a lifestyle intervention on the sex hormone in obese premenopausal women.

Background: Following the example of other countries, it is very important to educate patients on the correct use of inhalers by properly trained healthcare professionals, including pharmacists. Objectives: The aim of the study was to assess the quality and comprehensiveness of professional advice given by pharmacists on the use of inhalers, which was determined by the pharmacists’ level of training. Methods: The study was conducted from June 2019 to March 2020. 150 pharmacists from Poznan and Warsaw (Poland) were involved. Before the study began, the professional education of 240 pharmacists was conducted in Warsaw to implement standard operating procedures. The study used the model of a mystery shopper. Results: The conversation with a trained pharmacist lasted on average 5.5 min, with an untrained one—3.0 min (p < 0.0001). Placebo inhalers were used more often by trained pharmacists during patients’ education (p < 0.0001). Moreover, 10.3% of untrained pharmacists did not provide any education. Additionally, untrained employees’ quality of advice was assessed on an average of 3.5 points, while trained ones—7.6 points (p < 0.0001). Conclusions: This study has shown that there is a need for professional training among pharmacists in Poland, which translates into better patient education in the field of inhalation techniques.
