What is Variation?01:14

What is Variation?

18.6K
Apart from the measures of central tendency, distribution, outliers, and the changing characteristics of data with time, an important characteristic of any data set is its variation or spread. In some data sets, the data values are concentrated closely near the mean; in others, the data values are more widely spread out from the mean.
The range, standard deviation, standard error, and variance are the different measures of variation.
Range: The range is the difference between its maximum and...

Global Climate Change

29.0K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Variation

8.0K
An important characteristic of any set of data is the variation in the data. In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. The most common measure of variation, or spread, is the standard deviation, which is the square root of variance.
When independent and dependent variables are plotted on a scatter plot, the slope of a line is a value that describes the rate of change between the two...

Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

6.8K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Variation of Atmospheric Pressure01:18

Variation of Atmospheric Pressure

4.2K
Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...

Summary

Regional variations impact treatment outcomes for tubercular uveitis (TBU). Western geographic origin, African/Hispanic ethnicity, and immigrant status are linked to poorer survival in TBU patients.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Public Health

Background:

  • Tubercular uveitis (TBU) is an ocular manifestation of extrapulmonary tuberculosis.
  • Understanding regional variations in TBU management and outcomes is crucial for effective treatment.
  • This study addresses a gap in multinational data on TBU.

Purpose of the Study:

  • To investigate regional variations in management practices for tubercular uveitis (TBU).
  • To analyze treatment outcomes and survival rates across different geographic regions in TBU patients.

Main Methods:

  • Retrospective multinational cohort study involving 25 international eye care centers.
  • Inclusion of 945 patients with TBU and a minimum follow-up of 1 year.
  • Analysis of geographic variations in treatment outcomes using survival analysis, with defined criteria for treatment failure.

Main Results:

  • Analysis of 945 patients (1485 eyes) with TBU, predominantly Asian ethnicity (74.4%).
  • Most patients lacked overt symptoms or history of pulmonary tuberculosis (TB).
  • Poorer survival outcomes were observed in patients of western geographic origin, African/Hispanic ethnicity, and those with positive immigrant status.

Conclusions:

  • This is the first multinational analysis highlighting regional differences in TBU treatment outcomes.
  • Findings underscore the need for tailored strategies for at-risk groups, such as immigrants.
  • Recommendations for future collaborative studies with internists to develop best practice guidelines for TBU management.
