Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

9.7K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

X-linked Traits01:19

X-linked Traits

59.0K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

Sex-linked Disorders01:43

Sex-linked Disorders

109.3K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

86.8K
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Enzyme-Linked Immunosorbent Assay

17.8K
In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen.  Enzyme-substrate reaction allows the antigen to be visualized or...

Summary

Polypharmacy affects over half of elderly patients admitted to hospitals. Cardiovascular diseases, diabetes, dementia, and COPD are key predictors, necessitating careful medication review in this population.

Area of Science:

  • Geriatric Medicine
  • Clinical Pharmacy
  • Epidemiology

Background:

  • Elderly patients are highly susceptible to polypharmacy, the concurrent use of multiple medications.
  • Polypharmacy is often necessary but poses significant risks in older adults.
  • This study investigated polypharmacy prevalence and predictors in hospitalized elderly patients.

Purpose of the Study:

  • To determine the prevalence of polypharmacy in patients aged 65 years and older admitted to the hospital.
  • To identify independent predictors associated with polypharmacy in this demographic.

Main Methods:

  • A cohort of 310 patients (51% female, mean age 80.24 years) admitted consecutively was studied.
  • Data collected included demographics, medical history, current medications, and admission reasons.
  • Multivariate logistic regression analysis was employed to identify significant predictors of polypharmacy.

Main Results:

  • Polypharmacy was prevalent, affecting 53.5% of the study population.
  • Independent predictors included arterial hypertension, coronary artery disease, heart failure, atrial fibrillation, diabetes mellitus, dementia, and COPD.
  • Specific odds ratios and p-values highlight the strong associations between these conditions and polypharmacy.

Conclusions:

  • Cardiovascular diseases were strongly linked to polypharmacy in this elderly cohort.
  • Close physician monitoring is crucial for patients with polypharmacy to detect adverse drug reactions early.
  • While deprescribing is ideal, careful management is essential when polypharmacy is unavoidable.
