Classification of Illness01:17

Classification of Illness

8.1K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Factors Affecting Illness01:18

Factors Affecting Illness

4.7K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Prevalence and Incidence01:08

Prevalence and Incidence

1.0K
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.

3.0K
Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:

Hazard Ratio01:12

Hazard Ratio

311
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...

Biological Causes of Schizophrenia01:29

Biological Causes of Schizophrenia

204
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

Summary

Multimorbidity, the presence of multiple chronic diseases, is a growing global health challenge. This review summarizes common disease clusters, healthcare challenges, and future research needs to improve patient lives.

Area of Science:

  • Public Health
  • Gerontology
  • Clinical Medicine

Background:

  • The clustering of comorbidities (multimorbidity) presents a significant and escalating global health challenge.
  • Individuals with multiple diseases face complex daily management issues, impacting quality of life and family well-being.
  • Current research often excludes multimorbid individuals or focuses on single conditions, leaving a gap in understanding and management.

Purpose of the Study:

  • To review the increasing prevalence and common clusters of multimorbidity.
  • To highlight the challenges encountered by healthcare systems in managing patients with multiple conditions.
  • To explore avenues for enhancing future research to address multimorbidity effectively.

Main Methods:

  • This review synthesizes existing literature on multimorbidity prevalence and common disease clusters.

  • It examines reported challenges in healthcare delivery and patient management for individuals with multiple chronic conditions.
  • The review identifies opportunities and suggests directions for future research in the field of multimorbidity.

    • Main Results:

    • Multimorbidity is rising globally, posing significant difficulties for patients and healthcare providers.
    • Common clusters of diseases present unique management challenges.
    • There is a critical need for more inclusive research focusing on multimorbidity outcomes and interventions.

    Conclusions:

    • Addressing the growing problem of multimorbidity requires a concerted effort in research and healthcare strategy.
    • Future research should focus on multimorbidity as a distinct clinical entity to improve patient care and outcomes.
    • Enhanced understanding and management strategies are crucial for supporting individuals living with multiple chronic conditions.
