Scientific evidence suggests an association between obesity and oral diseases, including periodontal disease, dental caries, tooth erosion, xerostomia, and dentinal hypersensitivity. Maintaining optimal oral health is essential for obese patients, as compromised dentition or oral discomfort can influence dietary habits. However, managing oral health in obese individuals can be challenging due to anatomical limitations and lifestyle choices. Profound knowledge of obesity and its manifestations, the oral health professionals need to raise awareness and provide patients with comprehensive care. Pocrescophobia also known as obesophobia, is an intense fear of gaining weight. It affects both adoloscent women and men, manifesting as an irrational dread associated with weight gain. Like other phobias, obesophobia falls under the umbrella of anxiety disrders, leading to exaggerated anxiety when discussing or thinking about weight gain. Individuals with this fear may go to extreme lengths to avoid weight gain, which can increase the risk of developing eating disorders. Stress can lead to bruxism, wears away the occlusal surfaces and incisal edges, resulting in flat, shorter teeth. Smooth V-shaped cavities arise when lateral stresses surpass physiological limitations, resulting in gum recession and tooth discomfort. Canker sores, xerostomia, and lichen planus have all been linked to stress. By addressing both obesophobia and obesity as well as oral health, patients' overall well-being and quality of life can be improved.</p>","PeriodicalId":20777,"journal":{"name":"Przeglad epidemiologiczny","volume":"78 2","pages":"177-181"},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142293994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we discuss in detail meningitis and/or encephalitis in 2022 caused by Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae, and tick-borne encephalitis virus. OBJECTIVE. The aim of this study was an epidemiological assessment of the occurrence of meningoencephalitis and encephalitis in Poland in 2022, taking into account the analysis of the impact of the COVID-19 pandemic. MATERIAL AND METHODS. To analyze the epidemiological situation of neuroinfections in Poland, we used data sent to NIPH NIH–NRI by the Sanitary and Epidemiological Stations and published in the annual bulletins: \"Infectious Diseases and Poisons in Poland in 2022\" and \"Vaccinations in Poland in 2022\" as well as individual epidemiological interviews registered in the EpiBase system. RESULTS. In 2022, a total of 1747 cases of meningitis and/or encephalitis were registered in Poland. This was a 79.4% increase in the number of cases compared to 2021, when 974 cases were recorded. For infections of bacterial etiology, including cases of neuroborreliosis, the number of cases increased by 62.3% . The incidence of meningitis and/or encephalitis of N. meningitidis etiology meningitidis increased by 30.8%, with etiology of H. influenzae compared to 2021 increased by 300%, and for S. pneumoniae by 71.9%. Infections of viral etiology accounted for 52% of all registered cases. There was an increase in their number by 99.1% compared to 2021. Among viral infections, tick-borne encephalitis was the most numerous group, with 466 cases compared to 210 in 2021. SUMMARY AND CONCLUSIONS. The year 2022 showed an overall upward trend in the number of registered cases of bacterial and viral meningitis and/or encephalitis compared to 2021. Still, the observed number of cases of meningitis and/or encephalitis of both bacterial and viral origin remains below the levels observed in the period before the COVID-19 pandemic.","PeriodicalId":20777,"journal":{"name":"Przeglad epidemiologiczny","volume":"102 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141821085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ischemic stroke, exacerbated by modifiable risk factors like hypertension and household air pollution, poses a significant health challenge. Regional disparities, economic development, and healthcare inefficiencies underscore the need for targeted interventions and further research.This study aims to analyze trends in the burden of ischemic stroke across specific regions in sub-Saharan Africa from 2000 to 2019. The objective is to identify key changes in stroke burden progression and highlight modifiable risk factors.Utilizing World Health Organization (WHO) data from 2000 and 2019, national estimates of ischemic stroke DALYs in 49 sub-Saharan African countries were collected. DALYs were calculated per 100,000 population to reduce the impact of population size. Statistical analyses and visual representations using MapChart were employed to interpret the trends.The study reveals wide variations in ischemic stroke DALYs changes across sub-Saharan African countries from 2000 to 2019. Predominantly, countries in the Eastern and Southern regions experienced adverse increases, while those in the Central and West regions mostly exhibited declines in DALYs. Countries such as Lesotho, Zimbabwe, and Mauritius, saw the most significant DALYs increases, whereas Rwanda, Malawi, and Equatorial Guinea experienced the most favorable changes.Stroke is a pressing health concern in sub-Saharan Africa. Modifiable risk factors like hypertension and household air pollution necessitate targeted interventions. Tailored healthcare policies, reinforced health systems and comprehensive research into region-specific risk factors are crucial to alleviate stroke-related morbidity and mortality in the region. Addressing these challenges is vital to mitigate the increasing burden of stroke in the particular regions of sub-Saharan Africa.","PeriodicalId":20777,"journal":{"name":"Przeglad epidemiologiczny","volume":"41 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141663891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
