Insights

Older age, cerebrovascular disease, elevated white blood cell count, low platelet count, and abnormal liver enzymes (AST, CK-MB) are key predictors of COVID-19 mortality. These factors aid in early risk identification for optimal treatment strategies.

Area of Science:

  • Medical Research
  • Infectious Diseases
  • Critical Care Medicine

Background:

  • Coronavirus disease 2019 (COVID-19) presented a significant global healthcare challenge.
  • Understanding mortality predictors is crucial for managing the pandemic.

Purpose of the Study:

  • To identify independent predictors of mortality in COVID-19 patients.
  • To develop a nomogram for predicting COVID-19 patient mortality risk.

Main Methods:

  • A case-control study involving 96 deceased and 230 discharged COVID-19 patients.
  • Collection of demographic, epidemiological, clinical, and laboratory data upon admission.
  • Application of univariate and multivariate logistic regression analysis.

Main Results:

  • Independent predictors of mortality included age 60+ years, cerebrovascular disease, elevated white blood cell (WBC) count, low platelet count, elevated aspartate aminotransferase (AST), elevated cystatin C, elevated C-reactive protein (CRP), elevated creatine kinase isoenzymes (CK-MB), and elevated D-dimer.
  • A predictive nomogram demonstrated high discriminatory accuracy with a C-index of 0.903.

Conclusions:

  • Identified determinants can help stratify COVID-19 patients by mortality risk early in their disease course.
  • These findings can guide timely and optimal treatment decisions for high-risk individuals.

Controls in Experiments

When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Factors Affecting Illness

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,...

Causality in Epidemiology01:21

Causality in Epidemiology

Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
