Summary
Cloacal exstrophy research is concentrated in the USA, with thematic shifts towards surgical outcomes and prenatal diagnosis. Future work should enhance international collaboration and explore adult outcomes.
Area of Science:
- Medical research
- Congenital anomalies
- Bibliometrics
Background:
- Cloacal exstrophy (CE) is a complex congenital anomaly requiring multidisciplinary care.
- Significant surgical and clinical advances have occurred, but research trends lack comprehensive analysis.
- Bibliometric analysis offers a method to map the scientific landscape of CE research.
Purpose of the Study:
- To conduct a bibliometric and scientometric assessment of cloacal exstrophy research.
- To evaluate publication trends, authorship, institutional productivity, collaborations, and thematic evolution from 1959 to 2025.
Main Methods:
- Systematic bibliometric analysis of the Scopus database (up to August 2025).
- Data analysis using Scopus tools, VOSviewer, and Bibliometrix.
- Metrics included publication output, co-authorship, collaborations, keyword co-occurrence, and citation analysis.
Main Results:
- 289 publications identified (1959-2025), peaking in 2011.
- USA led research output (56%), with Johns Hopkins institutions being most productive.
- Research themes evolved from descriptive studies to surgical outcomes, prenatal diagnosis, and gender identity.
Conclusions:
- CE research is concentrated in US centers, with thematic shifts reflecting advances in fetal medicine and surgery.
- The field shows an established research structure.
- Future efforts should focus on international collaboration, adult outcomes, and novel therapeutic strategies.

01:24Evolution of New Traits in Microbes
Microorganisms evolve rapidly due to their large population sizes and short generation times, often exhibiting measurable changes within days under laboratory conditions. Natural selection acts on standing genetic variation, enabling the retention and amplification of beneficial traits that confer fitness advantages in changing environments.Adaptive Pigment Regulation in RhodobacterIn Rhodobacter, a genus of purple non-sulfur bacteria, light-harvesting pigments such as bacteriochlorophyll and...
01:08Evolution of Microbial Genome
Microbial genome evolution is a highly dynamic process shaped by continual gene gain and loss across species and strains. This genomic flexibility allows microorganisms to adapt rapidly to environmental pressures and interactions with other organisms. Central to understanding this diversity is the distinction between the core and pan genomes.The core genome comprises the genes shared by all sampled strains of a species, representing essential functions needed for fundamental cellular processes.
02:54Evolutionary Relationships through Genome Comparisons
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
01:26Evolutionary Processes in Microbes
Microbial evolution occurs rapidly due to short generation times and a variety of genetic processes, including horizontal gene transfer, mutation, recombination, and genetic drift. These mechanisms collectively enable microbes to adapt swiftly to changing environments.Horizontal gene transfer (HGT) allows genes to move between different species and occurs through three main mechanisms: conjugation, transformation, and transduction. Conjugation involves direct cell-to-cell contact for DNA...
01:36Overview of Exosomes
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.

01:54Convergent Evolution
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.The structures that arise from convergent evolution are called analogous structures. They are similar in function even if they are dissimilar in structure. Further, structures can be analogous while also...
