Insights

Mortality from circulatory diseases (CD) is increasing among the elderly in the Brazilian Amazon. Hotspots with high CD mortality are identified in Tocantins, Maranhão, and Mato Grosso.

Area of Science:

  • Public Health
  • Epidemiology
  • Gerontology

Background:

  • Circulatory diseases (CD) are the leading cause of death for the elderly in the Brazilian Amazon.
  • Understanding mortality trends is crucial for public health interventions.

Purpose of the Study:

  • To analyze standardized mortality rates of circulatory diseases (DCS) in elderly populations across Brazilian Amazon microregions.
  • To identify main causes of death and spatial distribution of DCS mortality from 1998 to 2007.

Main Methods:

  • Ecological study analyzing mortality rates standardized by CD and corrected for poorly defined causes.
  • Utilized linear regression, trend analysis, and Kernel spatial distribution for data analysis.
  • Focused on individuals aged 65 and above in the Brazilian Amazon between 1998 and 2007.

Main Results:

  • An increasing trend in CD mortality was observed (β1 = 28.34, p = 0.01), particularly in Maranhão and Tocantins.
  • Identified mortality hotspots in central Mato Grosso, northern Tocantins, eastern Pará, and southwestern Maranhão.
  • Higher mortality rates were noted in males compared to females, with increasing rates correlating with age. Acute myocardial infarction and hypertensive disease showed similar spatial patterns to overall CD, while cerebrovascular diseases had a different distribution.

Conclusions:

  • The Brazilian Amazon exhibits an increasing trend and high rates of mortality due to circulatory diseases.
  • Geographic areas with the highest mortality rates are concentrated around the periphery of the Brazilian Amazon, specifically in Tocantins, Maranhão, and Mato Grosso.

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Anatomy of the Circulatory System02:03

Anatomy of the Circulatory System

The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.
