Insights

Diagnosing unexplained infant deaths is challenging. This review synthesizes a diagnostic approach, emphasizing how new genomic sequencing technologies can aid in identifying genetic causes for neonatal and infantile demise.

Area of Science:

  • Genetics
  • Neonatal Medicine
  • Pediatric Pathology

Background:

  • Many infant deaths lack a confirmed diagnosis, with potential genetic or non-genetic causes.
  • Clinical decisions for investigations in dying or deceased infants are often uncertain for healthcare providers.
  • Peri-mortem studies are crucial for diagnosing unexplained infant deaths.

Purpose of the Study:

  • To review the current literature on evaluating unexplained neonatal and infantile deaths.
  • To synthesize a diagnostic approach for these cases.
  • To highlight the role of emerging genomic technologies in diagnosis.

Main Methods:

  • Literature review of diagnostic evaluations for unexplained infant demise.
  • Synthesis of a diagnostic strategy incorporating peri-mortem studies.
  • Focus on the application of advanced genomic sequencing.

Main Results:

  • Genetic disorders are a significant cause of infant mortality, often undiagnosed.
  • Genomic sequencing offers advanced diagnostic capabilities for unexplained deaths.
  • Interpretation of genomic findings requires detailed clinical and peri-mortem data.

Conclusions:

  • A structured diagnostic approach is essential for unexplained infant deaths.
  • Genomic technologies are increasingly vital for identifying genetic causes.
  • Integrating clinical, peri-mortem, and genomic data improves diagnostic yield.

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Kubler Ross's Stages of Dying

Elisabeth Kübler-Ross significantly advanced psychology's understanding of the process of dying with her influential book, On Death and Dying (1969). She focused on studying terminally ill individuals and outlined five stages commonly experienced when coping with death: denial, anger, bargaining, depression, and acceptance.
In denial, individuals reject the reality of their condition, often thinking, "This isn't true; I feel fine," as a way to protect themselves from...

Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Nursing Diagnosis01:22

Nursing Diagnosis

Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.
The nursing diagnosis focuses on evidence-based...

Hybridoma Technology01:31

Hybridoma Technology

Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Genome Size and the Evolution of New Genes03:21

Genome Size and the Evolution of New Genes

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.
