Survival and longevity of European rulers: geographical influences and exploring potential factors, including the Mediterranean diet - a historical analysis from 1354 to the twentieth century.

Significant regional variability in lifespan in Europe is influenced by environmental factors and lifestyle behaviors, including diet. This study investigates the impact of geographical region on the lifespan of European rulers spanning from the fourteenth century to the present day. By analyzing historical records and literature, we aim to identify region-specific dietary patterns and lifestyle factors that may have contributed to longer lifespans among rulers. The hypothesis to be tested is that rulers from Southern European countries, where the traditional Mediterranean diet is consumed by the local people, may exhibit longer lifespans compared to rulers from other regions, due to the well-documented health benefits associated with this dietary pattern. We extracted comprehensive information for each ruler, encompassing their sex, birth and death dates, age, age of enthronement, duration of rulership, country, and cause of death (natural vs. non-natural). To determine their nationality, we coded rulers based on their hypothetical present-day residence (2023). Utilizing the EuroVoc Geographical classification, we categorized the countries into four regions: Northern, Western, Southern, Central and Eastern Europe. While Cox regression models did not find significant differences in survival rates among regions, further analysis stratified by time periods revealed intriguing trends. Contrary to our initial predictions, the Northern region displayed better survival rates compared to the Southern region between 1354 and 1499, whereas survival rates were similar across regions from 1500 to 1749. However, after 1750, all regions, except the Southern region, exhibited significantly improved survival rates, suggesting advancements in healthcare and lifestyle factors. These findings underscore the dynamic influence of both region and time period on health and longevity. Interestingly, despite the prevalence of the Mediterranean diet in the Southern region of Europe, rulers from this region did not demonstrate longer lifespans compared to their counterparts in other regions. This suggests that additional lifestyle factors may have played a more prominent role in their longevity. In conclusion, our study sheds light on the intricate relationship between region, time period, and lifespan among European rulers. Although the Mediterranean diet is often associated with health benefits, our findings indicate that it alone may not account for differences in ruler longevity across regions. Further research is warranted to explore the impact of other lifestyle factors on the health and lifespan of European rulers throughout history.

Nutrition Strategies Promoting Healthy Aging: From Improvement of Cardiovascular and Brain Health to Prevention of Age-Associated Diseases.

BACKGROUND: An increasing number of studies suggest that diet plays an important role in regulating aging processes and modulates the development of the most important age-related diseases. OBJECTIVE: The aim of this review is to provide an overview of the relationship between nutrition and critical age-associated diseases. METHODS: A literature review was conducted to survey recent pre-clinical and clinical findings related to the role of nutritional factors in modulation of fundamental cellular and molecular mechanisms of aging and their role in prevention of the genesis of the diseases of aging. RESULTS: Studies show that the development of cardiovascular and cerebrovascular diseases, neurodegenerative diseases, cognitive impairment and dementia can be slowed down or prevented by certain diets with anti-aging action. The protective effects of diets, at least in part, may be mediated by their beneficial macro- (protein, fat, carbohydrate) and micronutrient (vitamins, minerals) composition. CONCLUSIONS: Certain diets, such as the Mediterranean diet, may play a significant role in healthy aging by preventing the onset of certain diseases and by improving the aging process itself. This latter can be strengthened by incorporating fasting elements into the diet. As dietary recommendations change with age, this should be taken into consideration as well, when developing a diet tailored to the needs of elderly individuals. Future and ongoing clinical studies on complex anti-aging dietary interventions translating the results of preclinical investigations are expected to lead to novel nutritional guidelines for older adults in the near future.

Serum ghrelin level and TNF-α/ghrelin ratio in patients with previous myocardial infarction.

BACKGROUND AND AIMS: Studies investigating serum ghrelin level in atherosclerosis yielded contradictory results. Interaction of ghrelin with adipocytokines is obscure in cardiovascular diseases. We undertook this study to determine which molecules influence ghrelin level and to see whether post-myocardial infarction (MI) patients have decreased ghrelin levels. METHODS: In this cross-sectional study, acyl-ghrelin concentration was determined by radioimmunoassay in sera of 171 patients (ages 62 ± 6 years, mean ± SD) with previous MI and 81 age-matched referent subjects. We evaluated the associations of ghrelin with insulin, adiponectin, leptin, resistin, fetuin-A and tumor necrosis factor-alpha (TNF-α). RESULTS: Patients had lower ghrelin levels compared to referent subjects (240.55 ± 59.33 vs. 337.96 ± 30.75 pg/mL, p <0.001) even after excluding diabetic and obese patients (240.63 ± 54.08 vs. 337.96 ± 30.75, p <0.001). In multivariate analysis, insulin (ß = -0.327, p <0.001) and adiponectin (ß = 0.301, p <0.001) determined ghrelin level (R(2) = 0.199, p <0.001). There was no association between ghrelin and TNF-α levels. In discriminant analysis using ghrelin, adiponectin, leptin, fetuin-A, resistin and TNF-α, the structure matrix revealed ghrelin and TNF-α as strongest predictors for belonging to the patient group (0.760 and -0.569, respectively). Using these two parameters, 89.7% of cases were correctly classified. Subjects with high TNF-α/ghrelin ratio had 11.25 times higher chance for belonging to the patient group (95% CI 5.80-21.80; χ(2) (1) = 215.6, p <0.001) CONCLUSIONS: Acylated ghrelin levels are decreased in patients with coronary atherosclerosis, independently of body weight and the presence of type 2 diabetes mellitus. Ghrelin level is determined by elevated insulin and decreased adiponectin levels. Ghrelin alone or in combination with TNF-α may prove to be a novel indicator of coronary atherosclerosis.

[Meteorology and the human body: two hundred years of history]. / Az emberi szervezetre ható meteorológiai jelenségek hatásainak története az elmúlt kétszáz évben.

Modern meteorology was started in the 18th century, with the establishment of observer networks through countries. Since then, temperature, pressure and purity of air, quantity of powder have been measured and the effects of changes on the human body have been studied. New theories have been set relating to the atmospheric properties of microorganisms. Changes of pathogens in the context of climatic changes have been also studied.

[Dental aspects of general symptoms in the 18th century]. / Altalános kórképek fogászati vonatkozásai a XVIII. században.

In the 18th century, numerous diseases with symptoms of oral cavity were cured by chirurgien-dentist, barber-surgeons, or tooth drawer. The so called "dentitio difficilis" was blamed for the high children mortality, therefore gum cut or use of leeches was advised as a treatment. Both acute and chronic type of gum inflammation was called scurvy. It seems that the mechanical removal of plaque was enough to cure the scurvy as it was written in advertisements from that time. Syphilis was present in the everyday life throughout centuries, and assumed to cause different stigmas in the oral cavity. Today we consider theses stigmas as the toxic signs of mercury treatment.

[Beautiful girls' ugly malady--selected passages from the history of guilty sex and syphilis]. / Szép lányok csúnya betegsége, avagy szemelvények a bûnös szex és a szifilisz történetébôl.

In Budapest at the end of the 19th century, visiting brothels was an important part of night life, including the risk of some venereal disease (v.d.) like syphilis, the in-vogue illness of the age. The expansion of prostitution could be explained with the continuous growth of economy and social development as a consequence of urbanization. Prostitution has grown in innumerable forms, levels and places in order to meet all requirements since this was the only tolerated form of sexuality "out of homes". The police headquarters' duty was to control the observation of rules prescribed for prostitutes. Data and information were available only on registered "professional" prostitutes because references on hidden prostitution were hard to find. Liberalization of the strict rules and regalements on brothels and "staff" began at the time when the increase of prostitution and simultaneously, of syphilis overreached the capacity of the Police and the Health Care System.

[Model program for screening oral cancers in the Roma population]. / Modellprogram ajak-szájüregi daganatok szûrôvizsgálatára roma populációban.

Oral cancer has been identified as a significant public health threat. It is reported that about 3,800 new cases of oral cancer are diagnosed in Hungary each year with approximately 1,700 associated deaths. Oral cancer is the 6th most common cancer in men. Most oral cancers are preventable; 75% of oral cancers are related to tobacco use, alcohol use, or use of both substances together. While there is insufficient evidence to support or refute the use of visual examination as a method of screening for oral cancer in the general population, screening in high-risk populations is highly recommended. It was presumed that high-risk behavior including tobacco and alcohol use is one of the characteristics of Roma people. The main aim of the study was to elaborate a screening model program for the Roma population to determine risk factors of oral cancer and establish early diagnosis hence to reduce morbidity and mortality. In the program we planned to survey the risk factors in the target population, establish the diagnosis of oral cancer and/or pre-cancer and direct the patients to health care facilities. First we determined the target population in four Hungarian towns with the help of Roma social workers and local public health officers. We assembled a questionnaire on risk factors. Training for Roma social workers and screening personnel was also accomplished. Screening for oral precancerous lesions and cancer and survey the risk factors in the target population were performed at the same time. Patients screened to be positive were referred to specialists. Altogether 1,146 persons, 656 male and 490 female (age 20-77 years, mean 40 years), participated in the screening; 84% of them reported on some kind of complaints. We have got valid data on risk factors in connection with oral cancer. More than fifty percent of participants did not clean their teeth regularly, 75% were smokers, while 45% drunk alcohol regularly. 1,6% of screened participants had oral lesions that did not require referral to a specialist, while 2.3% of the screened subjects had referable oral mucosal lesions including leukoplakia. The overwhelming majority (93%) of participants screened to be positive did not see dentist regularly. As a conclusion, we elaborated a screening model program, which is applicable for disadvantaged (e.g. Roma) population to determine risk factors of oral cancer and establish early diagnosis hence to reduce morbidity and mortality. We surveyed the risk factors in the target population, established the diagnosis of oral cancer and/or pre-cancer lesions and directed the patients to care facilities. We also assisted them to get appropriate long-term care and follow-up. The importance of screening activities targeted on high-risk population was underlined.

Dental practice in Hungary at the end of the eighteenth century.

The consumer society, with its pursuit of niceties rather than merely necessities, came late to Hungary. After the expulsion of the Turks, reconstruction of the country was inevitably very Austria-dependent, with Hungary cast in the role of the granary of the Empire and excluded from the economic changes affecting much of the rest of western Europe. As regards dental care, the wealthy might seek sophisticated treatment in Vienna or later in Pest where dental science first emerged. The University was founded at Nagyszombat (today, Trnava in Slovakia) where the Faculty of Medicine was founded in 1770. The qualification of Magister artis dentariae was awarded from 1799. Dental treatment was also provided by other types of practitioner throughout the country, namely by itinerant 'healers' who operated at fairs, frequently extracting the wrong teeth.
