Opis:
Butanodiacetale (BDA) są stabilnymi, optycznie czynnymi blokami budulcowymi wykorzystywanymi w syntezie produktów naturalnych. Otrzymać je można na drodze syntezy z tanich substratów: D-mannitolu, kwasu L-askorbinowego, L-winianu dimetylowego, oraz D-winianu dimetylowego. Usztywniona struktura butanodiacetali daje możliwość zastosowania ich w syntezie asymetrycznej. Przedstawiono przegląd literaturowy dotyczący syntezy butanodiacetali oraz ich zastosowania do syntezy małocząsteczkowych i wielkocząsteczkowych naturalnych związków optycznie czynnych.
Butane diacetals (BDAs) are stable, optically active building blocks used in the synthesis of natural products. They can be synthesized from cheap substrates such as: D-mannitol, L-ascorbic acid, dimethyl L-tartrate and dimethyl D-tartrate. The rigid structure of butane diacetals makes possible their application in asymmetric synthesis. The article presents literature review on synthesis of butane diacetals and their application in the synthesis of natural small and large optically active compounds.

Introduction. Research on the meaning of health and health behaviors is important for the development of health education programmes which should be tailored to the needs of patients. Objective. The aim of the study is to determine whether the place of residence and age have an impact on health behaviours and the perception of health by women past menopause. Materials and method. A survey method and three research instruments were employed: authors’ questionnaire, the Health Behaviour Inventory and the Health Criteria List by Juczyński, and the Kupperman Index. The study was carried out among a sample of 102 women after menopause hospitalised in a hospital in eastern Poland. Results. The overall health behaviour indicator (HBI) in the study group was found to reach an average value of 80.1±12.7points. A higher HBI indicator was found to be characteristic of urban rather than rural residents; however, there was no statistically significant difference (p>0.05). The age of respondents did not differentiate statistically their health behaviours (p>0.05). Women who reported their last menstruation before the age of 50 obtained higher results in the dimension of health practices (HPs) than those whose last menstruation ceased after the age of 50 (p<0.05). The respondents attributed the highest importance to health, understood as a property, a state and a goal. Statistically significant differences were observed in the importance of the statement according to which health is a process of “being able to work without tension and stress”, as the respondents from urban areas assigned to it a higher average weight than those from rural areas (p< 0.05). Conclusions. A higher overall HBI, as well as indicators for particular categories, were characteristic of women from urban areas. Age did not significantly differentiate the women’s health behaviours. Rural residents were dominant in the group of women who rated their health to be very good or good. The respondents attributed the highest importance to health understood as a property, state and goal.

Opis:
Introduction. Osteoporosis is a chronic condition with serious sequela, including primarily bone fractures, and impacts on almost all spheres of human life. It is important for patients undergoing treatment to accept their health status and feel satisfied with life. Objective. The aim of the study was to determine the relationship between socio-demographic factors, duration of the illness, self-assessment of the patient’s knowledge of osteoporosis, and also between illness management support and acceptance of the illness and life satisfaction among females with chronic osteoporosis, resident in rural areas. Materials and method. The study, conducted from September 2016 – June 2017, involved 207 patients of the Clinic of Orthopaedics and Rehabilitation and the Clinic of Gynaecology at the Independent Public Teaching Hospital No. 4 in Lublin, eastern Poland. The study used the Acceptance of Illness Scale (AIS) and the Satisfaction With Life Scale (SWLS). Statistical analysis was performed with Student’s t-test, analysis of variance (ANOVA), Tukey’s range test, and chi-squared test. A p-value of <0.05 defined statistical significance of differences. The analysis was performed using commercial SPSS Statistics 19 software (IBM Corp., Armonk, NY, USA). Results. The respondents showed average acceptance of their illness (22.2±6.9) and relatively low satisfaction with life (14.7±5.6). Older age, low level of education, poor living conditions, prolonged illness, and frequent ailments are all associated with lower acceptance of the illness and poorer life satisfaction. Conclusions. As part of their treatment, chronically ill patients should be provided with appropriate support, in particular from healthcare personnel, health education and improved living conditions.

Objective. The aim of the study is to compare the hope of rural and urban inhabitants in the terminal stage of a neoplastic disease covered by stationary hospice care. Materials and method. The study was carried out among patients in the terminal phase of a neoplastic disease. They were patients of both 24-hour and daily palliative and hospice care units throughout the country. The study group consisted of 246 patients, average age – 59.5, the youngest respondent was 18 and the oldest – 90. The B. L. Block (NCN-36) test, prepared for people struggling with serious life-threatening diseases, was used. Comparison of the results with regard to the place of residence was based on the test Friedman ANOVA and Kendall compatibility factor. The general comparison of hope in individual dimensions and globally with the division into the degree of urbanization, was based on the Kruskal-Wallis test. Results. On the basis of factor analysis, 4 scales constructed from 8 items branch were distinguished. The following scales are used to study hope in the situational dimension – health, the telek-temporal dimension – goals, the spiritual dimension – religious beliefs and in the emotional-affective (affective) dimension – motivations. Conclusions. The strength of hope in people in the terminal phase of cancer, residing in villages, settlements, small, medium and large cities, was similar and depended on its magnitude. Of all the manifestations of hope, the greatest variation in results occurred in the subjects when they encountered serious problems and difficulties. The inhabitants of medium-sized cities were characterized by a higher hope at that time.

Opis:
The most effective and the cheapest method of cardiovascular disease prevention is changing lifestyle. Cardiovascular disease is caused by many factors. They include: a diet rich in saturated fat and cholesterol, smoking, a sedentary lifestyle, physical inactivity, overweight and obesity. The aim of the research was to assess the level of knowledge of the students of the Medical University about cardiovascular disease prevention. Material and methods: Research was conducted on 200 students of the Medical University of Lublin, residing in the Student House No. 4 in Lublin. Self-authorship questionnaires were used to assess the level of knowledge of the students of the Medical University about cardiovascular disease prevention. Research results: The students of the Medical University have broad knowledge about the influence of physical activity, diet, cigarettes and alcohol use on cardiovascular disease prevention. 90.5 percent of the respondents know that smoking greatly increases the risk of cardiovascular disease. More than a half of the students are aware that excessive alcohol consumption has a negative impact on the cardiovascular system. 38.67 percent of the respondents recognize moderate alcohol consumption as protective for cardiovascular disease. The remaining 3.13 percent of the students have no knowledge about this issue. Almost half of the respondents (45 percent) is aware that psychosocial factors have an impact on the cardiovascular system. 86.5 percent of the students believe that there is a correlation between cardiovascular disease and factors such as: low socioeconomic status, social isolation, stress, negative emotions, depression. The remaining 13.5 percent of the respondents have incomplete knowledge about this issue. Almost the half of the respondents knows that type A personality increases the risk of cardiovascular disease, whereas the remaining 52 percent of the students have incomplete knowledge about this issue.

Introduction. A healthy lifestyle can help older people maintain their functional ability and, therefore, satisfaction with life. An important aspect of health promotion is the assessment of lifestyle factors over which patients have some control. Objective. The aim of this study was to analyze the lifestyle of the elderly in urban and rural areas using the Fantastic Life Inventory (FLI). Materials and method. The research group comprised 138 people aged 65–94 years (M = 72.41, SD = 6.90). Participants were recruited from urban 78 (56.5%) and rural 60 (43.5%) areas. The FLI used in this study has 25 closed-ended questions that explore nine domains, including physical, psychological, and social lifestyle components. Results. The overall lifestyle of most seniors was ‘excellent’ (45.7%) or ‘very good’ (41.3%); none of the respondents scored in the lowest category – ‘needs improvement’. The domains that mostly demonstrated the need for a change were related to activity, nutrition, insight, sleep, stress. Participants from rural areas tended to have lower scores in the activity (p= 0.017) and nutrition (p= 0.015) domains. The lifestyle of the elderly is determined by several factors, including age, gender, health status, level of education, and the place of residence. Conclusion. The majority of older persons demonstrated an ‘excellent’ or ‘very good’ lifestyle with healthy habits. The adoption of healthy lifestyle patterns, in particular a regular balanced diet and proper physical activity, can help prevent functional limitations among the elderly in rural areas.

Opis:
The off-label use of medicinal products raises many interpretation-related issues, not only among physicians, but also pharmacists and lawyers. The use of drugs in a manner other than that specified in the Summary of Product Characteristics is not regulated by Polish law. The authors’ goal is to discuss the topic mainly from the practical perspective, while also considering its theoretical aspects, and to identify systemic solutions to several problems, that are extremely important for the proper functioning of the entire healthcare system. The paper highlights that there is a fine line between experimental medicinal practices and those that are in keeping with current medical knowledge.
