Safety of Progestogen Hormonal Contraceptive Methods during Lactation: An Overview.

BACKGROUND: Breastfeeding is a process for not only nourishing infants but also for building a unique emotional bond between mother and child. Therefore, the ideal contraception during lactation should not affect lactation (milk composition, milk volume) and offspring development. OBJECTIVES: This study aims to analyze the literature on the safety of progestogen hormonal contraceptive methods during lactation. METHODS: We conducted a thorough search across various databases, including the National Library of Medicine (PubMed), and the Cochrane Database, Drugs and Lactation Database (LactMed). Our search utilized specific phrases such as: "lactation" and "breastfeeding" and "oral contraception" with "drospirenone" or "desogestrel", with "subcutaneous etonogestrel implant" or "etonogestrel implant", with "levonorgestrel-releasing intrauterine system", and "emergency contraception", with "levonorgestrel" or "ulipristal acetate". CONCLUSIONS: Based on published scientific reports, progestogen hormonal contraceptives can be considered a relatively safe solution for women desiring to continue feeding their infant with their milk while using hormonal contraception. It is important to seek guidance on selecting the best contraception method based on the latest medical knowledge, tailored to the individual needs and clinical circumstances of each woman and place of residence. A woman should always be informed of the potential risks of such a treatment and then allowed to make her own decision based on the knowledge received from a specialist.

Incorporation of Anions into Anodic Alumina-A New Track in Cr(VI) Anodizing Substitution?

Aluminum technical alloys are well known for their outstanding mechanical properties, especially after heat treatment. However, quenching and aging, which improve the mechanical properties, by the formation of Cu-rich zones and phases that are coherent with the matrix and block the dislocation motion, cause uneven distribution of the elements in the alloy and consequently make it prone to corrosion. One method providing satisfactory corrosion protection of aluminum alloys is anodizing. On an industrial scale, it is usually carried out in electrolytes containing chromates that were found to be cancerogenic and toxic. Therefore, much effort has been undertaken to find substitutions. Currently, there are many Cr(VI)-free substitutes like tartaric-sulfuric acid anodizing or citric-sulfuric acid anodizing. Despite using such approaches even on the industrial scale, Cr(VI)-based anodizing still seems to be superior; therefore, there is an urge to find more complex but more effective approaches in anodizing. The incorporation of anions into anodic alumina from the electrolytes is a commonly known effect. Researchers used this phenomenon to entrap various other anions and organic compounds into anodic alumina to change their properties. In this review paper, the impact of the incorporation of various corrosion inhibitors into anodic alumina on the corrosion performance of the alloys is discussed. It is shown that Mo compounds are promising, especially when combined with organic acids.

Quality of Life of Women with Polycystic Ovary Syndrome.

Background and Objectives: Polycystic ovary syndrome (PCOS) is an endocrine disorder characterized by multiple hormonal and metabolic abnormalities, including insulin resistance, hyperandrogenism, and disturbances in lipid and carbohydrate metabolism. The objective of this study is to assess the quality of life of women diagnosed with polycystic ovary syndrome (PCOS) and to identify any factors within the study group that may impact the scores related to quality of life. Materials and Methods: This research was carried out among women diagnosed with PCOS. An original questionnaire, developed through an online Google Forms survey, was utilized as the research instrument and distributed through social networks and support groups to women facing PCOS. This study encompassed a participant pool of 200 women with PCOS, aged 24 years or older. For the analytical component, Pearson's χ2 test was employed-a nonparametric test designed to assess the relationship between two variables measured on a qualitative scale. The chosen level of statistical significance was set at p < 0.05. Results: The analysis revealed that the quality of life of the women under study was not linked to the duration of the disease or comorbidities. However, a significant association was observed with the inconvenience caused by PCOS symptoms. Women experiencing very bothersome symptoms of PCOS reported a lower quality of life compared to those with symptoms rated as not very bothersome. Despite the majority of women with PCOS rating their quality of life as good or very good, they often find the associated symptoms of PCOS bothersome. Women reporting lower quality of life tend to acknowledge the impact of PCOS on their lives, experience a sense of lack of control over the disease, struggle with depression, and do not accept their physical appearance. Conclusions: Hence, the support from specialists like endocrinologists, gynecologists, and nutritionists becomes crucial for many women dealing with PCOS. Adopting a healthy lifestyle, incorporating a balanced diet, and engaging in regular physical activity can assist in managing the troublesome symptoms of PCOS, thereby enhancing overall quality of life. In instances of emotional difficulties, seeking psychological support is equally important, and the significance of support and acceptance from loved ones should not be overlooked.

Factors Affecting Women's Assessment and Satisfaction with Their Childbirth.

Background and Objective: Childbirth is one of the most significant experiences in a woman's life. The manner in which childbirth unfolds and is experienced can be influenced by various factors, including the birthing environment and the woman's attitude and preparation. Taking a holistic view of childbirth, it becomes apparent that addressing the basic physiological needs during childbirth can significantly influence the comfort and sense of security of laboring women. The aim of this research was to assess the level of satisfaction among women with their experience during childbirth and to identify its determinants. Materials and Methods: This study included 275 women who had given birth within the past 15 years and were up to 40 years of age. The research method employed was a diagnostic survey, involving a self-designed questionnaire. Results: discussing the birth plan with the midwife, the ability to ask questions during labor, consuming meals during labor, water immersion, listening to music during labor, assuming vertical positions during the second stage of labor, and skin-to-skin contact are associated with increased satisfaction with the childbirth experience. Conclusions: The study findings revealed that the highest levels of satisfaction were reported in connection with the interactions with medical staff during childbirth and the quality of facilities available during delivery. Conversely, the lowest levels of satisfaction were associated with the possibility of using pain relief methods during labor.

New Possibilities for Hormonal Vaginal Treatment in Menopausal Women.

Hormonal vaginal therapy is an effective treatment option for women who experience vaginal symptoms related to hormonal changes. Estrogen and prasterone are widely used as vaginal treatments, particularly for urogenital atrophy. These symptoms may include vaginal dryness, itching, burning, and pain during sexual intercourse, all of which can significantly affect a woman's quality of life. Previous studies have indicated that such treatment improves tissue elasticity, moisturizes the vagina, and can have a substantial impact on urine incontinence and vaginal microflora and decreases dyspareunia. Hormonal therapy is also useful and commonly used before vaginal surgical treatment. Prasterone is quite a new option for vaginal therapy in Poland and is mainly recommended for dyspareunia in menopausal women. The study related to prasterone therapy emphasizes its effectiveness and safety, making it advantageous to explore its beneficial impact. This paperwork aims to summarize the mechanism of action as well as the effects of both drugs and their beneficial action during vaginal treatment.

The Influence of Oral Drotaverine Administration on Materno-Fetal Circulation during the Second and Third Trimester of Pregnancy.

Background and Objectives: The study aimed to evaluate the effect of the oral administration of drotaverine on maternal and fetal circulation as measured by Doppler sonography in women with a risk of preterm birth. Materials and Methods: The present prospective study was conducted on 34 women with singleton pregnancy at 26-36 weeks of gestation. Doppler flow and pulsatility index (PI) assessments of the umbilical artery, fetal middle cerebral artery, and uterine arteries were performed before and 90-120 min after oral drotaverine administration. Results: There were no statistically significant differences between the Doppler assessment (PI Uma-umbilical artery, MCA-middle cerebral artery, and ltUta-left uterine artery) before drotaverine administration and 90-120 min after oral intake, but there were statistically significant differences between the PI assessment of the rtUta (right uterine artery, 0.55 vs. 0.75, p = 0.05) and the mean of the Uta (0.66 vs. 0.74, p = 0.03). For changes in the CUR (cerebro-umbilical ratio) and % changes in the CUR and mean PI of the Uta, there was no correlation with obstetric history, AFI (amniotic fluid index), gestation week, infertility history, systolic pressure, or diastolic pressure. There was a statistically positive correlation between changes in the CUR and % change in the CUR and body weight and in height. Conclusions: Drotaverine has no statistically significant influence on the MCA and Uma PI. The oral administration of drotaverine has an impact on PI rtUta and the mean PI Uta.

Canonical analysis of concentrations of toxic metals in endometrium of women with gynecological disorders.

OBJECTIVES: Among the main adverse environmental factors, we usually distinguish the impact of heavy metals, especially Cd and Pb. Apart from the carcinogenic and toxic properties, their potential, stimulating estrogen receptors effect (metaloestrogens) is strongly emphasized; as well as participation in gene regulation mechanisms (epigenetic). The aim of this study is to examine if there is a special scheme of concentrations of heavy metals accumulated in the female endometrium in certain pathologies: endometrial hyperplasia, endometrial cancer, endometrial polyps and miscarriages. The control group consisted of patients with abnormal uterine bleeding or functional bleeding with correct histopathological findings. MATERIAL AND METHODS: The study was performed on 92 women. Microwave induced plasma atomic emission spectrometry was used to assess metals concentrations in tissue material and the results of obtained concentrations were converted to µg/kg. The calculations were performed using discriminant and canonical analyses and revealed four discriminant functions. RESULTS: The results showed that metal's tissue concentrations vary in different types of histopathological diagnosis and the scheme of concentrations might be characteristic for analyzed diagnosis. Pb and Al has the most substantial impact on discrimination. CONCLUSIONS: Endometrium may accumulate toxic metals such as: Pb, Cd, Ni, Mn, Cu, Zn, Al, Cr. It can be assumed that there are characteristic distributions of toxic metals concentrations for individual histopathological diagnoses.

HEALTH RISK RELATED TO EXPOSURE TO TOXIC COMPOUNDS CONTAINED IN MINERAL AND SPRING WATERS.

OBJECTIVE: The aim: The study aimed to assess the content of selected toxic compounds in mineral and spring waters available on the Polish market regarding potential health risks to consumers. PATIENTS AND METHODS: Materials and methods: Selected mineral and spring waters available on the Polish market were the study's objects. The content of such chemical compounds as arsenic, cadmium, lead, copper, and mercury in selected mineral and spring waters was analyzed. The content of metals in the samples was determined by inductively coupled plasma mass spectrometry (ICP-MS). Additionally, a literature review was performed to determine nitrates contamination of bottled waters available on the Polish market. Based on the collected data, an assessment of exposure and health risk to consumers was performed. RESULTS: Results: Arsenic had the highest mean concentration in the analyzed water samples. Consumption of such contaminated waters may be a significant health risk factor for consumers. Literature data indicate a relatively low content of nitrates in bottled waters available on the Polish market. Consumption of such mineral waters is not a significant source of exposure and does not translate into a significant health risk for consumers. CONCLUSION: Conclusions: To ensure consumers' health safety, there is a need to monitor the content of potentially harmful compounds in mineral and spring waters available on the Polish market.

Functional annotation of the 2q35 breast cancer risk locus implicates a structural variant in influencing activity of a long-range enhancer element.

A combination of genetic and functional approaches has identified three independent breast cancer risk loci at 2q35. A recent fine-scale mapping analysis to refine these associations resulted in 1 (signal 1), 5 (signal 2), and 42 (signal 3) credible causal variants at these loci. We used publicly available in silico DNase I and ChIP-seq data with in vitro reporter gene and CRISPR assays to annotate signals 2 and 3. We identified putative regulatory elements that enhanced cell-type-specific transcription from the IGFBP5 promoter at both signals (30- to 40-fold increased expression by the putative regulatory element at signal 2, 2- to 3-fold by the putative regulatory element at signal 3). We further identified one of the five credible causal variants at signal 2, a 1.4 kb deletion (esv3594306), as the likely causal variant; the deletion allele of this variant was associated with an average additional increase in IGFBP5 expression of 1.3-fold (MCF-7) and 2.2-fold (T-47D). We propose a model in which the deletion allele of esv3594306 juxtaposes two transcription factor binding regions (annotated by estrogen receptor alpha ChIP-seq peaks) to generate a single extended regulatory element. This regulatory element increases cell-type-specific expression of the tumor suppressor gene IGFBP5 and, thereby, reduces risk of estrogen receptor-positive breast cancer (odds ratio = 0.77, 95% CI 0.74-0.81, p = 3.1 × 10-31).

CYP3A7*1C allele: linking premenopausal oestrone and progesterone levels with risk of hormone receptor-positive breast cancers.

BACKGROUND: Epidemiological studies provide strong evidence for a role of endogenous sex hormones in the aetiology of breast cancer. The aim of this analysis was to identify genetic variants that are associated with urinary sex-hormone levels and breast cancer risk. METHODS: We carried out a genome-wide association study of urinary oestrone-3-glucuronide and pregnanediol-3-glucuronide levels in 560 premenopausal women, with additional analysis of progesterone levels in 298 premenopausal women. To test for the association with breast cancer risk, we carried out follow-up genotyping in 90,916 cases and 89,893 controls from the Breast Cancer Association Consortium. All women were of European ancestry. RESULTS: For pregnanediol-3-glucuronide, there were no genome-wide significant associations; for oestrone-3-glucuronide, we identified a single peak mapping to the CYP3A locus, annotated by rs45446698. The minor rs45446698-C allele was associated with lower oestrone-3-glucuronide (-49.2%, 95% CI -56.1% to -41.1%, P = 3.1 × 10-18); in follow-up analyses, rs45446698-C was also associated with lower progesterone (-26.7%, 95% CI -39.4% to -11.6%, P = 0.001) and reduced risk of oestrogen and progesterone receptor-positive breast cancer (OR = 0.86, 95% CI 0.82-0.91, P = 6.9 × 10-8). CONCLUSIONS: The CYP3A7*1C allele is associated with reduced risk of hormone receptor-positive breast cancer possibly mediated via an effect on the metabolism of endogenous sex hormones in premenopausal women.

Common Susceptibility Loci for Male Breast Cancer.

BACKGROUND: The etiology of male breast cancer (MBC) is poorly understood. In particular, the extent to which the genetic basis of MBC differs from female breast cancer (FBC) is unknown. A previous genome-wide association study of MBC identified 2 predisposition loci for the disease, both of which were also associated with risk of FBC. METHODS: We performed genome-wide single nucleotide polymorphism genotyping of European ancestry MBC case subjects and controls in 3 stages. Associations between directly genotyped and imputed single nucleotide polymorphisms with MBC were assessed using fixed-effects meta-analysis of 1380 cases and 3620 controls. Replication genotyping of 810 cases and 1026 controls was used to validate variants with P values less than 1 × 10-06. Genetic correlation with FBC was evaluated using linkage disequilibrium score regression, by comprehensively examining the associations of published FBC risk loci with risk of MBC and by assessing associations between a FBC polygenic risk score and MBC. All statistical tests were 2-sided. RESULTS: The genome-wide association study identified 3 novel MBC susceptibility loci that attained genome-wide statistical significance (P < 5 × 10-08). Genetic correlation analysis revealed a strong shared genetic basis with estrogen receptor-positive FBC. Men in the top quintile of genetic risk had a fourfold increased risk of breast cancer relative to those in the bottom quintile (odds ratio = 3.86, 95% confidence interval = 3.07 to 4.87, P = 2.08 × 10-30). CONCLUSIONS: These findings advance our understanding of the genetic basis of MBC, providing support for an overlapping genetic etiology with FBC and identifying a fourfold high-risk group of susceptible men.

KNOWLEDGE AND ATTITUDES OF YOUNG PEOPLE IN THE FIELD OF EATING DISORDERS.

OBJECTIVE: The aim: To examine the level of knowledge and attitudes of high school students in the field of eating disorders. PATIENTS AND METHODS: Materials and methods: The study group consisted of students of a randomly selected village school (Jendrzejow) and the municipal school (Siemianowice Slaskie). The study was conducted using an original survey consisting of 10 questions regarding the knowledge and attitudes of respondents towards eating disorders. RESULTS: Results: A total of 313 students (242 female and 71 male) participated in the study. 44.7% of respondents from the village school and 56.6% of respondents from the municipal school were dissatisfied with their appearance; 21.6% and 27.9%, respectively, were currently using the diet. 68% of students from Jedrzejow and 53.3% of students from Siemianowice Slaskie made an attempt to reduce body weight at least once in their lives. 55.1% of the village school respondents and 47.4% of the municipal school respondents noticed the influence of the media on the desire to achieve a slim figure. Girls showed better knowledge about eating disorders than boys (p = 0.008). Over 70% of students of both surveyed high schools believed that people with eating disorders are unable to cope with the disease on their own. Only 6.7% of students of the municipal school and 12.92% of students of the village school gave themselves a very good grade. CONCLUSION: Conclusions: There is a need to educate young people more broadly about eating disorders and the risk factors for their occurrence.

Women's Healthcare Services since the COVID-19 Pandemic Outbreak in Poland.

The COVID-19 pandemic had a direct impact on the extent of guaranteed healthcare services. Many gynecologists', obstetricians', and midwives' offices were closed, laboratories suspended their activities, the collection of necessary tests was delayed, and women had to wait much longer for test results than they had to previously. General women's healthcare prophylactic programs were suspended or delayed. In 2020, screening financed by public funds covered less than one-seventh of the female population in Poland. As medical teams, professionals, clinicians, and scientists, we have been facing a challenge to help, protect, and care for one of the most vulnerable population groups, pregnant women. A significant part of that challenge has been in preventing the spread of severe COVID-19, along with other preventable diseases, among women who are pregnant, who are in labor, or who have recently given birth.

ASSOCIATION BETWEEN EATING HABITS AND PHYSICAL ACTIVITY IN PRIMARY SCHOOL STUDENTS.

OBJECTIVE: The aim: The study aimed to assess the association between the physical activity level and eating habits of primary school students. PATIENTS AND METHODS: Material and methods: 139 children attending one of the Polish primary school or football school were included. The research tool was author's anonymous survey. RESULTS: Results: The high physical activity level was observed in 34.1% of boys and in 8.8% of girls. As the level of physical activity increased, the consumption of vegetables and fruits also increased. Whole grain bread, coarse-grained groats, whole grain pasta and brown rice were more popular among students with a high physical activity level. The greater the physical activity, the greater the amount of water drank by students. The consumption of sweets, fast food, and ready-made meals, such as frozen pizza or Chinese soup, decreased with increased physical activity. The choice of healthier substitutes for unhealthy snacks was declared by students with moderate or high physical activity level. There was no correlation between BMI and age and the physical activity level. Girls were less active than boys. CONCLUSION: Conclusions: More active physically children had better eating habits and were more aware of healthy eating principles than less active people.

ASSESSMENT OF ADULT EATING HABITS IN THE NUTRITIONAL PREVENTION OF STROKE.

OBJECTIVE: Introduction: Lifestyle modification, including changing eating habits, plays an essential role in the prevention of stroke. The aim: The study aimed to assess the nutritional prevention of cerebrovascular diseases in adult inhabitants of Poland. PATIENTS AND METHODS: Material and Methods: The study was conducted using the author's questionnaire among 145 women and 76 men, aged 18 - 30 (53.9%) and 50 - 70 (46.1%) years. RESULTS: Results: The following stroke risk factors were found in the examined group: overweight or obesity (46.6%), lack of regular physical activity (48%), smoking (33%), hypertension (22.1%), dyslipidemia (8.6%), diabetes (5.9%), and cardiac arrhythmias (6.3%). The younger subjects compared to older ones more often declared the daily consumption of whole-grain cereal products and vegetables, fish at least once a week, and they preferred vegetable oils. On the other hand, older subjects declared the consumption of sweets, sweet drinks, salt, and fast food less frequently than younger ones. Also, fruits were more often chosen by older people. Both groups declared similar moderate consumption of milk and dairy products with reduced fat content, lean meat, and alcohol. Only 38% of respondents considered their eating habits to be appropriate. CONCLUSION: Conclusions: The eating habits of examined adults only partially met the recommendations regarding the nutritional prevention of stroke. In some elements, younger people were more likely to follow appropriate dietary recommendations, while older people were more appropriate in others. The education regarding the principles of the nutritional prevention of cerebrovascular diseases is still necessary and should be age-appropriate.

DNA methylation of the long intergenic noncoding RNA 299 gene in triple-negative breast cancer: results from a prospective study.

Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype associated with a high rate of recurrence and poor prognosis. Recently we identified a hypermethylation in the long noncoding RNA 299 (LINC00299) gene in blood-derived DNA from TNBC patients compared with healthy controls implying that LINC00299 hypermethylation may serve as a circulating biomarker for TNBC. In the present study, we investigated whether LINC00299 methylation is associated with TNBC in a prospective nested breast cancer case-control study within the Generations Study. Methylation at cg06588802 in LINC00299 was measured in 154 TNBC cases and 159 breast cancer-free matched controls using MethyLight droplet digital PCR. To assess the association between methylation level and TNBC risk, logistic regression was used to calculate odd ratios and 95% confidence intervals, adjusted for smoking status. We found no evidence for association between methylation levels and TNBC overall (P = 0.062). Subgroup analysis according to age at diagnosis and age at blood draw revealed increased methylation levels in TNBC cases compared with controls in the young age groups [age 26-52 (P = 0.0025) and age 22-46 (P = 0.001), respectively]. Our results suggest a potential association of LINC00299 hypermethylation with TNBC in young women.

[Influence of dietary trends on the nutrition of the youth].

OBJECTIVE: Introduction: Dietary trends such as consumption of lactose-free and gluten-free products or the use of alternative slimming diets are gaining increasing popularity, especially among young people. They determine their dietary choices, which are important from the point of view of human health. Unconventional diets are still considered as effective weight loss methods. The use of alternative diets may cause shortages of an essential nutrients, increase the risk of chronic non-communicable diseases and lead to the formation of incorrect eating habits. Balanced diet, in contrast to the alternative diet, takes into account the principles of rational nutrition and nutritional recommendations of the Institute of Food and Nutrition (IZZ). The aim: To investigate the influence of popular dietary trends on nutrition of high school adolescences. PATIENTS AND METHODS: Material and methods: Subjects were adolescences in the age of 17-21 years attending high schools in Ruda Slaska (262 students, including 157 women and 105 men). Self-constructed questionnaire was applied in the study. Participation in the study was anonymous and voluntary. RESULTS: Results: In more than a half of young women (54,8%) and men (52,4%) the body mass deficiency was revealed (BMI<18 kg/m2). 33,6% of the respondents were on the non-balanced diets at least once in their lives. High school students knew gluten-free and lactose-free products but dietary trends, such as the consumption of gluten-free and lactose-free products, did not affect their diet. The main source of nutritional knowledge among respondents were their friends (78,2%). CONCLUSION: Conclusions: The results of the conducted research indicate the need to implement educational programs on the principles of proper nutrition. The increasing awareness of the youth in this regard may contribute to reducing the interest in still popular alternative diets among young people and taking appropriate health behaviors by them.

Epigenome-wide association study for lifetime estrogen exposure identifies an epigenetic signature associated with breast cancer risk.

BACKGROUND: It is well established that estrogens and other hormonal factors influence breast cancer susceptibility. We hypothesized that a woman's total lifetime estrogen exposure accumulates changes in DNA methylation, detectable in the blood, which could be used in risk assessment for breast cancer. METHODS: An estimated lifetime estrogen exposure (ELEE) model was defined using epidemiological data from EPIC-Italy (n = 31,864). An epigenome-wide association study (EWAS) of ELEE was performed using existing Illumina HumanMethylation450K Beadchip (HM450K) methylation data obtained from EPIC-Italy blood DNA samples (n = 216). A methylation index (MI) of ELEE based on 31 CpG sites was developed using HM450K data from EPIC-Italy and the Generations Study and evaluated for association with breast cancer risk in an independent dataset from the Generations Study (n = 440 incident breast cancer cases matched to 440 healthy controls) using targeted bisulfite sequencing. Lastly, a meta-analysis was conducted including three additional cohorts, consisting of 1187 case-control pairs. RESULTS: We observed an estimated 5% increase in breast cancer risk per 1-year longer ELEE (OR = 1.05, 95% CI 1.04-1.07, P = 3 × 10-12) in EPIC-Italy. The EWAS identified 694 CpG sites associated with ELEE (FDR Q < 0.05). We report a DNA methylation index (MI) associated with breast cancer risk that is validated in the Generations Study targeted bisulfite sequencing data (ORQ4_vs_Q1 = 1.77, 95% CI 1.07-2.93, P = 0.027) and in the meta-analysis (ORQ4_vs_Q1 = 1.43, 95% CI 1.05-2.00, P = 0.024); however, the correlation between the MI and ELEE was not validated across study cohorts. CONCLUSION: We have identified a blood DNA methylation signature associated with breast cancer risk in this study. Further investigation is required to confirm the interaction between estrogen exposure and DNA methylation in the blood.

[Nutrition in selected old age diseases].

In the population of Poland, as well as in other European countries, an aging process is taking place. It is expected that in Poland in 2050, up to 35% of the population may be seniors. With increasing age, there are numerous changes in the body that necessitate the modification of the current diet. Incorrect diet is a risk factor for many old age diseases, including neurodegenerative diseases, osteoporosis, atherosclerosis, stroke, type 2 diabetes and hypertension. The aim of this study is to review the nutrition recommendations in selected diseases of the elderly. The diet of seniors should provide the right amount of nutrients and be adapted to existing diseases. A proper diet can reduce the risk of complications from senile diseases.

[Knowledge on cardiovascular risk factors and symptoms of stroke among inhabitants of rural communite].

OBJECTIVE: Introduction: Stroke is one of the leading causes of mortality and disability in the world. A wide knowledge of risk factors for cerebrovascular diseases is one of the main elements of primary prevention, while knowledge of stroke symptoms can significantly speed up treatment and reduce negative health effects. The aim: To assess the knowledge about stroke and risk factors of cerebrovascular diseases among the inhabitants of the randomly selected rural community (in Lodz Province). PATIENTS AND METHODS: Material and methods: The study included 143 adult residents of Rzasnia. The research was carried out using a self-constructed questionnaire, prepared on the basis of available literature. RESULTS: Results: The average score obtained from the knowledge survey on stroke was 5.79 +/- 3.47 (maximum number of points - 14). The average number of points in people with a family history of stroke was statistically significantly higher (7.46±3.31) than in those with no stroke in the family (4.20±2.98 ) (p <0.001). There was no statistically significant difference between the average number of points and gender (women - 6.13±3.55 points, men - 5.64±3.55, NS) and age (R = -0.1, NS ). However, the positive correlation between educational level and the score obtained in our questionnaire was found (R =0.4, p <0.05). The average number of correctly listed risk factors was: 0.6 ± 1.6. At least one risk factor was reported by only 34% of respondents. Respondents most often mentioned: excessive alcohol consumption (18%), smoking (18%), hypertension (14%), atherosclerosis (11%). The average number of correctly listed symptoms of stroke was: 1.2±1.3. At least one symptom of stroke was reported by only 58% of respondents. The respondents most often reported: headache (29%), speech disorders (22%), gait disturbances (13%), and sensory disorders (13%). If a stroke was suspected, the majority of respondents would call an ambulance (94%). CONCLUSION: Conclusions: Knowledge of the residents of the chosen rural commune about the stroke is not satisfactory and should be supplemented with an educational program that would include as many people as possible.
