Which of the following is the most recently recognized vulnerable population?

People with a history of mental illness are also a group that is vulnerable to the effects of disasters. The stressors associated with disasters are commonly recognized as risk factors that may exacerbate a range of preexisting conditions. Following traumatic events, individuals with prior or ongoing psychiatric conditions are more likely to experience a relapse or an exacerbation of these conditions, as well as the development of other forms of psychopathology, including PTSD. In addition to the stress effects associated with common exposures, specific elements of the event and its aftermath may trigger key vulnerabilities. For example, bereavement or the loss of a support network or job may result in a relapse of major depression. The intense activity and officialdom of the recovery may heighten paranoid ideation in those experiencing psychotic conditions.

Indigenous peoples may face particular difficulties. Their backgrounds may have already involved life threat through premature mortality and racist violence. Other losses may involve family disruptions, deaths, and loss of land, culture, identity, and meaning. Such losses may entail both literal and symbolic dislocation from place, tribe, or community. Socioeconomic, educational, and other disadvantages may all contribute further to this background of traumatization. Disaster stressors superimposed on this context further increase the likelihood of adverse outcomes for these individuals and communities.

Mesenchymal Stromal Cells to Improve Solid Organ Transplant Outcome

Marlies E.J. Reinders, ... Ton J. Rabelink, in Kidney Transplantation, Bioengineering and Regeneration, 2017

24.6.3 Safety Aspects in Clinical Trials With MSCs

In the vulnerable population of kidney transplant recipients, patient safety and prevention of adverse (immune) reactions is essential. Since transplant recipients have already an increased risk of (opportunistic) infections and malignancies due to the concomitant immunotherapy, it is very difficult to determine the additional risk of MSC infusions. Clinical studies should be performed under ethically approved protocols and serious adverse events (SAEs) and suspected unexpected serious adverse reactions (SUSARs) should be carefully recorded and reported to the proper authorities. Important potential risks in renal transplant recipients include direct toxicity of the MSC infusion, malignancies, and risks for over immune suppression and immunogenicity, as also extensively reviewed elsewhere.12,78

EGGS

D.J. McNamara, H.S. Thesmar, in Encyclopedia of Human Nutrition (Second Edition), 2005

Summary

For nutritionally vulnerable populations, including the poor, the very young, the very old, pregnant women, and those suffering from chronic diseases, eggs are an affordable nutrient-dense source of high-quality protein important for maintaining health and facilitating recovery. Pregnancy is an especially important time to optimize the intake of high-quality protein and other essential nutrients to reduce the risk of low birth weight and the associated development of chronic diseases and other health problems during the infant's adult life. Eggs also serve as an important dietary source of choline during pregnancy and lactation, providing the fetus and newborn with choline for brain development. In addition, eggs provide a satiety effect, which, in view of the global problem of obesity, can be a valuable addition to weight-loss and weight-maintenance programs. For various populations, from infants to the aged, there are a multitude of health reasons to include nutrient-dense eggs as part of the diet, and for many of these groups it is economically feasible.

The high-quality protein, many nutritional components, low caloric content, affordability, blandness, ease of digestibility, and satiety response all make eggs ideal for inclusion in the diet at all ages, from very young to very old, and in times of both health and convalescence.

Eggs

D.J. McNamara, in Encyclopedia of Human Nutrition (Third Edition), 2013

Summary

For nutritionally vulnerable populations including the poor, the very young, the very old, pregnant women, and those suffering from chronic diseases, eggs are an affordable, nutrient-dense source of high-quality protein important for maintaining health and facilitating recovery. Pregnancy is an especially important time to optimize intake of high-quality protein as well as other essential nutrients to reduce the risk of low birth weight and the associated development of chronic diseases and other health problems during the future adult years of the infant. Eggs also serve as an important dietary source of choline during pregnancy and lactation to provide choline to the fetus and newborn for brain development. In addition, eggs provide a satiety effect which, in view of the global problem of obesity, can be a valuable addition to weight-loss and weight-maintenance programs. For these various populations, from infant to aged, there are a multitude of health reasons to include nutrient-dense eggs as part of the diet, and for many of these groups it can be economically feasible.

The high-quality protein, many nutritional components, low caloric content, affordability, blandness, ease of digestibility, and satiety response are all characteristics that make eggs ideal for inclusion in the diet across the lifespan, from very young to very old, and under all conditions, health or convalescence. As noted in the Dietary Guidelines 2010, “Independent of other dietary factors, evidence suggests that one egg (i.e., egg yolk) per day does not result in increased blood cholesterol levels, nor does it increase the risk of cardiovascular disease in healthy people.”

Modeling of Vulnerable Subjects

Xin Jin, in Basic Finite Element Method as Applied to Injury Biomechanics, 2018

Abstract

Although people in vulnerable populations, such as children and elderly females, are at a greater risk of injury in automotive crashes than middle-aged and midsized occupants, automotive safety designs are based on current crash-test dummies of limited number of shapes and sizes that do not adequately represent such vulnerable populations. Computational models that represent age- and gender-dependent changes in impact responses are necessary. To close the gap between injuries for which current safety testing is aimed at and the actual injuries suffered by children and elderly females who have been insufficiently protected, CHARMs (The Collaborative Human Advanced Research Models) have been developed to represent a 10-year-old child and a 70-year-old female. In this chapter, we introduce the development of CHARM-10 and CHARM-70F models as examples to show the general procedures and specific challenges of developing FE models of vulnerable subjects.

First, anthropometric investigation is performed with geometric and compositional datasets to ensure the model is a good representative of the target population. Second, multiblock meshing strategies are adopted to obtain good mesh quality and flexibility for changing mesh densities. Finally, component and whole-body validations are performed against different loading conditions to finalize material constitutive parameters and to assess the biofidelity of the model.

Who are the most vulnerable populations?

There are a number of groups that are considered vulnerable populations, including racial and ethnic minorities, the economically disadvantaged, and those with chronic health conditions. For vulnerable populations, their health and healthcare issues may be exacerbated by social factors.

What are the 4 main vulnerable populations?

In the social realm, vulnerable populations include those living in abusive families, the homeless, immigrants, and refugees. The needs of these populations are serious, debilitating, and vital, with poor health in 1 dimension likely compounded by poor health in others.

Which of the following is an example of vulnerable population?

There are some groups who have been identified by the federal regulations as “vulnerable populations”: pregnant women and fetuses, minors, prisoners, persons with diminished mental capacity, and those who are educationally or economically disadvantaged.

Which of the following is specified as a vulnerable population?

The federal regulations require that IRBs give special consideration to protecting the welfare of particularly vulnerable subjects, such as children, prisoners, pregnant women, mentally disabled persons, or economically or educationally disadvantaged persons.
