Regardless of being most used demographic indicator of longevity, life expectancy has few limitations too; and it arise mainly due to irregular mortality patterns in particular age group. This paper aims to analyze the trend of remaining life expectancies in different age groups and examines the highest observed life expectancies along with lower and upper bounds of life expectancies for Bangladesh; a country where early aged mortality is present remarkably. To estimate the lower and upper bounds of life expectancies in particular age; corresponding survival fractions have been taken into account, which gave more flexible concepts about longevity measures. Obtained results indicate decline in the gap between early aged life expectancies for both sexes in Bangladesh; which suggests that the full population, rather than just the more selected survivors, may anticipate a longer life that was previously only the domain of those who survived past the early years.

Abstract Objectives Worldwide, culinary herbs and spices have been used for centuries as food flavoring, preservative agents, or for their known health benefits. Over the last decade, they are gaining much significance as the dietary polyphenols contained have been recognized to have health promoting benefits and preventive role in most chronic diseases. Little data exists however referring to the actual level of knowledge of these foods or the dietary intake . While the consumption of herbs and spices is generally higher in Asian countries, it has been an increasing trend in their intake in developed countries as result of changing food habits and preference for ethnic and spicy food. The aim of this preliminary study was to evaluate the level of knowledge and intake of herbs and spices, while promoting the importance of healthy dietary changes that would benefit throughout the lifespan. Methods The knowledge of the 30 herbs and spices to be studied, and common dietary patterns referring to this type of foods was evaluated in a very heterogeneous group in terms of age (15–65), ethnic and cultural background, educational level or living status, through a very simple Food Frequency Questionnaire specially adapted in this case for herbs and spices. Results While the importance of creating healthy eating habits from early years and school across the entire lifespan is well recognized, data shows it takes time learning and creating new routines. The number of herbs and spices known increases with age (from 50% in the age group under 20, to 100% in the age group 50–60). The number of herbs and spices most known in all age groups is relatively reduced, and includes: ginger, garlic, chili, turmeric, basil, lemongrass, coriander and curry. The age group 50–60 displays also the highest frequency in using them on a daily basis. The favorite and most used among all age groups are: garlic, ginger, onion, lemongrass, basil and turmeric. The most frequent reason for using spices in all groups is “flavor”. The level of education, living status, or location do not seem to influence much. Conclusions General nutrition knowledge is an important part of improving diet quality and healthy eating attitudes, thus, the earlier learned the patterns, the healthy and happier outcomes. Further study in a larger number of participants and on a wider selection of herbs and spices is definitely needed for validation. Funding Sources None.

SummaryCollagen mediated platelet aggregation caused -5.6 ± 6.7% inhibition and +39.1 ± 15.2% potentiation of prekallikrein activation in plasma from normal healthy volunteers between 20–40 and 50–65 years of age, respectively (n = 15, p <0.01). The amouns of platelet factor-four (PF4) released in the two groups were not significantly different. Collagen treatment in the presence of indomethacin caused +11.5 ± 3.6% and +59.6 ± 19.5% potentiation in the 20–40 and 50–65 age groups respectively (p <0.02). Adrenaline mediated platelet aggregation caused -55.2 ± 7.1% and -35.2 ± 8.3% inhibition in the 20–40 and 50–65 age groups, respectively. Collagen treatment of platelet-deficient-plasma and platelet-rich-plasma in EDTA also caused potentiation of prekallikrein activation.The results indicate that the observed degree of prekallikrein activation after platelet aggregation is a net result of the inhibitory effect of PF4 and the potentiatory effect of activated platelets. The potentiatory effect was greater after collagen treatment as compared to adrenaline treatment, and in the 50–65 age group as compared to the 20–40 age group.

The practice of placing deprived children having least or no emotional and material resources, in orphanages has since long been prevailing in socio -economically poor Asian countries. A sample of 30 children residing in orphanage in district Anantnag in the age group of 13-18 years was selected for the present study. Most of the children were found socially and psychologically disturbed. As per Indian Academy Paediatrics (IAP) classification with respect to weight for age the condition was not bad that as approximately 67% percent of the children were found to be normal. In the same way height for age as per Waterloo’s classification shown that more than half of the children were normal. On clinical examination approximately 47% of children were normal, while as rest were suffering from dispigmentation of hair, moon face, xerosis of skin cheilosis, magenta tongue, spongy bleeding gums, oedema, conjuctival xerosis, and mottled dental enamel. The findings indicated that nutritional intake was deficient for all nutrients when compared to, Recommended Daily Allowances Chart (RDA) for all age groups which may be linked to poor planning of menus in orphanages.

Abstract:: Epigenetic changes in COVID-19 host, a pandemic-causing infectious agent that globally incapacitated communities in varying complexities and capacities are discussed, proposing an analogy that epigenetic processes contribute to disease severity and elevate the risk for death from infection. Percentages of hospitalization, with and without intensive care, in the presence of diseases with increased ACE2 expression, were compared, based on the best available data. Further analysis compared two different age groups, 19-64 and ≥65 years of age. The COVID-19 disease is observed to be the most severe in the 65-and-higher-age group with preexisting chronic conditions. This observational study is a non-experimental empirical investigation of the outcomes of COVID-19 in different patient groups. Results are promising for conducting clinical trials with intervention groups. To ultimately succeed in disease prevention, researchers and clinicians must integrate epigenetic mechanisms to generate valid prescriptions for global well-being.

The Difference

Though there are exhaustive data about participation, performance trends, and sex differences in performance in different running disciplines and races, no study has analyzed these trends in stair climbing and tower running. The aim of the present study was therefore to investigate these trends in tower running. The data, consisting of 28,203 observations from 24,007 climbers between 2014 and 2019, were analyzed. The effects of sex and age, together with the tower characteristics (i.e., stairs and floors), were examined through a multivariable statistical model with random effects on intercept, at climber’s level, accounting for repeated measurements. Men were faster than women in each age group (p < 0.001 for ages ≤69 years, p = 0.003 for ages > 69 years), and the difference in performance stayed around 0.20 km/h, with a minimum of 0.17 at the oldest age. However, women were able to outperform men in specific situations: (i) in smaller buildings (<600 stairs), for ages between 30 and 59 years and >69 years; (ii) in higher buildings (>2200 stairs), for age groups <20 years and 60–69 years; and (iii) in buildings with 1600–2200 stairs, for ages >69 years. In summary, men were faster than women in this specific running discipline; however, women were able to outperform men in very specific situations (i.e., specific age groups and specific numbers of stairs).

The age of information (AoI) has been widely used to quantify the information freshness in real-time status update systems. As the AoI is independent of the inherent property of the source data and the context, we introduce a mutual information-based value of information (VoI) framework for hidden Markov models. In this paper, we investigate the VoI and its relationship to the AoI for a noisy Ornstein–Uhlenbeck (OU) process. We explore the effects of correlation and noise on their relationship, and find logarithmic, exponential and linear dependencies between the two in three different regimes. This gives the formal justification for the selection of non-linear AoI functions previously reported in other works. Moreover, we study the statistical properties of the VoI in the example of a queue model, deriving its distribution functions and moments. The lower and upper bounds of the average VoI are also analysed, which can be used for the design and optimisation of freshness-aware networks. Numerical results are presented and further show that, compared with the traditional linear age and some basic non-linear age functions, the proposed VoI framework is more general and suitable for various contexts.
