AIM: To examine the trends in the leading causes of deaths in centenarians in Hong Kong. METHODS: Descriptive analyses of vital statistics data on mortality in Hong Kong from 2001 to 2010 were carried out. RESULTS: The number of centenarians' deaths increased by 136% in 10 years, from less than 28 men and 166 women in 2001 to 80 men and 378 women in 2010. During the study period, the top leading cause of death was pneumonia, accounting for 33...

More and more people are living into the 90s or becoming centenarians. But, the gift of increased 'age span' seldom equates with an improved 'health-span'. Governments across the world are expressing concern about the epidemic of chronic disease, and have responded by initiating policies that make prevention, reduction and treatment of chronic disease, a public health priority. But understanding, how to age long and well, with the avoidance of chronic disease and later life complex disease morbidity is challenging...

BACKGROUND: Ventricular-arterial (VA) coupling is a central determinant of cardiovascular system performance and cardiac energetics. This index is expressed by the Ea/Ees ratio, where the effective arterial elastance (Ea) indicates the net arterial load exerted on the left ventricle and the left ventricular end-systolic elastance (Ees) is a load-independent measure of left ventricular chamber performance. METHODS: Thirty-three centenarians (100.6 ± 1.2 years, range 99-105 years, 10 M) without cardiovascular diseases underwent a complete echocardiographic evaluation and an instantaneous arterial blood pressure measurement, to characterize the Ea/Ees ratio and its two determinants indexed to body surface area...

Background: With the continued rise in the proportion of the oldest-old in high income countries, it is of interest to know whether the functional health of today's oldest-olds is better or worse than in previous cohorts. Using two Danish centenarian birth cohorts born twenty years apart we aimed at investigating if the later born cohort had better functioning in terms of activities of daily living (ADL). Methods: Identification, methodology and assessment instruments were identical in the 1895-West and 1915-West Birth Cohort Studies: All persons living in the western part of Denmark and turning 100 years old in 1995 and 2015, respectively...

Bifidobacteria are one of the major components in human microbiota that are suggested to function in maintaining human health. The colonization and cell number of Bifidobacterium species in human intestine vary with ageing. However, sequential changes of Bifidobacterium species ranging from newborns to centenarians remain unresolved. Here, we investigated the gut compositional changes of Bifidobacterium species over a wide range of ages. Faecal samples of 441 healthy Japanese subjects between the ages of 0 and 104 years were analysed using real-time PCR with species-specific primers...

The article presents the results of a study of centenarians (25 patients older than 90 years) residents of Almaty, suffering from coronary artery disease (CAD) of different severity, for the purpose of definition of biological age of CAD and identify factors influencing aging process. Significant positive correlation between the thickness of an intragastric partition and indexes of chronological age, due biological age was defined. We assume that the hypertrophy of walls of a left ventricle (LV) is the main morphological indicator of an aging of cardiovascular system...

Influenced by a special local environment, the proportion of centenarians is particularly high in some places, known as "blue zones". Blue zones are mysterious regions that continue to attract research. This paper explores the spatial distribution of the longevity population in a typical Chinese longevity region. Longevity evaluation indexes are used to analyze the longevity phenomenon in 88 towns between 2011 and 2015. Our research findings show that longevity is more important than birth rate and migration in shaping the degree of deep aging in the research region...

Leukocyte telomere length and serum levels of high-molecular-weight adiponectin and dehydroepiandrosterone-sulfate (DHEA-S) were assessed in association with nutrition and performance status (PS) in Japanese centenarians. Twenty-three centenarians (five men, 18 women) were classified according to their PS 1 (nearly fully ambulatory, n = 2), 2 (in bed less than 50% of daytime, n = 10), 3 (in bed greater than 50%, n = 6), and 4 (completely bedridden, n = 5). Leukocyte telomere length was determined by the hybridization protection assay, and the adiponectin and DHEA-S levels were measured by chemiluminescent enzyme immunoassay...

Ageing involves a progressive decline of the body's regulatory systems including immune system. Adenosine regulates immune function by interaction with its receptors, mainly adenosine A2A receptor, present on the surface of immune cells. Furthermore, cellular response to this nucleoside is highly dependent on its extracellular concentration that is regulated by ecto-enzymes such as CD39 and CD73. Therefore, the aim of this study was to investigate the effect of age on adenosine A2A receptor, CD39 and CD73 gene expression...

BACKGROUND: In the "fourth stage" of epidemiological transition, the distribution of non-communicable diseases is expected to shift to more advanced ages, but age-specific changes beyond 80 years of age have not been reported. METHODS: This study aimed to evaluate demographic and health transitions in a population aged 80 years and over in the United Kingdom from 1990 to 2014, using primary care electronic health records. Epidemiological analysis of chronic morbidities and age-related impairments included a cohort of 299,495 participants, with stratified sampling by five-year age group up to 100 years and over...

Over recent decades, economic living conditions have dramatically improved in South Korea, which now represents one of the most developed nations. At the same time, its twin in the North remains one of the poorest countries on earth. Thus, the Korean peninsula represents a unique historical experiment that allows for study of the effects of environment on human development under a variety of ceteris paribus cultural, genetic and climatic conditions. Previous studies comparing the biosocial performances of the two Koreas have focused on indicators such as weight, height, mid-upper arm circumference and age at menarche...

OBJECTIVES: This study examined the main sources of strain and the presence of psychological distress in a sample of centenarians' children who assumed the role of primary caregivers. METHOD: A sample of 43 children (M age = 67.10 ± 6.67 years; 90.7% female) caring for a centenarian parent was interviewed and asked about their overall caregiving experience. Information on caregiving burden (Zarit Burden Interview) and psychological distress (Hospital Anxiety and Depression Scale) was also obtained...

OBJECTIVES: The purpose of this study was to explore the pattern of mortality above the age of 100 years. In particular, we aimed to examine whether Scandinavian data support the theory that mortality reaches a plateau at particularly old ages. Whether the maximum length of life increases with time was also investigated. METHODS: The analyses were based on individual level data on all Swedish and Danish centenarians born from 1870 to 1901; in total 3006 men and 10 963 women were included...

AIM: To examine the relationships between two epigenetic clocks, aging and exceptional longevity. MATERIALS & METHODS: Participants were from three adult cohorts with blood DNA methylation data (Illumina 450 K, n = 275, 34-103 years). Epigenetic age (DNAmage) and age acceleration measures were calculated using the Hannum and Horvath epigenetic clocks. RESULTS: Across all cohorts, DNAmage was correlated with chronological age. In the long-lived cohort (Sydney Centenarian Study; 95+, n = 23), DNAmage was lower than chronological age for both clocks...

An impressive and coherent series of epidemiological data from different populations (New England Americans, Mormons, Ashkenazi Jewish, Icelandic, Okinawan Japanese, Italians) suggests that long-lived subjects able to reach the extreme limits of human life, such as centenarians and supercentenarians, represent an extraordinary and informative model to identify the mechanisms responsible for healthy aging and human longevity. In most studies, genetic, demographic and phenotypic characteristics of longevity are discussed separately...

Probiotics are live microorganisms that have beneficial effects on host health, including extended lifespan, when they are administered or present in adequate quantities. However, the mechanisms by which probiotics stimulate host longevity remain unclear and very poorly understood. In a recent study (Nat. Commun. 8, 14332 (2017) doi: 10.1038/ncomms14332), we used the spore-forming probiotic bacterium Bacillus subtilis and the model organism Caenorhabditis elegans to study the mechanism by which a probiotic bacterium affects host longevity...

Apolipoproteins play a crucial role in lipid metabolism with implications in cardiovascular disease, obesity, diabetes, Alzheimer's disease, and longevity. We quantified 7 apolipoproteins in plasma in 1067 individuals aged 56-105 using immunoassays and explored relationships with APOE polymorphism ε2/3/4, vascular health, frailty, and cognition. ApoA1, ApoA2, ApoB, ApoC3, ApoE, ApoH, and ApoJ decreased from mid-life, although ApoE and ApoJ had U-shaped trends. Centenarians had the highest ApoE levels and the lowest frequency of APOE ε4 allele relative to younger groups...
