Frailty syndrome is commonly seen in the aged and reflects multi-system physiological change. However, with reduced functional reserve and resilience frailty is also known to be common in the HIV infected population. This study outlined an easily administered screening test to identify HIV patients with frailty. When significant components of frailty are identified, clinicians will be able to focus on amelioration of the problem and promote reversion to the pre-frail state.

Persons infected with HIV are often frail, depressed and live a sedentary lifestyle for which conventional exercise is too taxing. Here, we present an exercise protocol that ameliorates aspects of frailty in HIV-infected persons. An exergame integrating cognitive control was developed using biosensors that measured balance, weight-shifting and obstacle crossing.

Here, we present a protocol to assess frailty in the perioperative setting using point-of-care ultrasound to measure quadriceps thickness. This method offers a practical, non-invasive alternative to traditional assessment methods, potentially enhancing perioperative care by quickly identifying frail patients.

Symmetric Bihemispheric Postmortem Brain Cutting to Study Healthy and Pathological Brain Conditions in Humans

Organized brain cutting procedures are necessary to correlate specific neuropsychiatric phenomena with definitive neuropathologic diagnoses. Brain cuttings are performed differently based on various clinico-academic contingencies. This protocol describes a symmetric bihemispheric brain cutting procedure to investigate hemispheric differences in human brain pathologies and to maximize current and future biomolecular/neuroimaging techniques.
FAQs
Each assessed condition, symptom, functional limitation, or laboratory finding contributes to the overall deficit count when present. That count is divided by the number of evaluated items, producing a proportion rather than a simple diagnosis or symptom total. This structure captures the combined burden of age-related changes and supports comparisons among individuals with different patterns of deficits.
A broad deficit set reflects the fact that biological vulnerability can arise from several age-related conditions, symptoms, functional limitations, and laboratory findings at the same time. Combining these domains provides a more comprehensive health profile than concentrating on a single disorder. The resulting measure can distinguish differences in overall resilience even when individuals share no single dominant condition.
Chronological age indicates how long an individual has lived, whereas the Frailty Index characterizes accumulated health deficits. Two people of the same age may therefore receive different scores because their conditions, symptoms, functional abilities, or laboratory findings differ. This helps aging research compare health states across populations without treating age alone as a complete description of biological condition.
The score provides an estimate of how accumulated deficits may affect an individual’s ability to withstand stress, illness, or injury. A greater proportion of deficits represents greater biological vulnerability within the evaluated set. In research, this information helps relate differences in health status to outcomes such as hospitalization, disability, and mortality.
Researchers first select a broad set of age-related conditions, symptoms, functional limitations, and laboratory findings for assessment. They then determine which evaluated deficits are present for each individual, count those deficits, and divide the count by the total number assessed. The resulting proportion can be used to characterize health state and compare participants or populations.
The measure is useful when researchers need to compare health states across populations or examine aging beyond chronological age. It can also support studies linking biological vulnerability with hospitalization, disability, and mortality. Because it summarizes accumulated deficits, investigators can use it to characterize differences in functional health while studying the biology of aging.
Researchers can use Frailty Index scores to characterize participants’ baseline burden of deficits and examine health status in relation to an intervention. Changes in the score provide a way to assess whether accumulated vulnerability and functional health differ across study conditions. This makes the measure relevant to research focused on preserving functional health during aging.
