Hospitals-II

1.1K
Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

What is Variation?01:14

What is Variation?

17.6K
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...

Conservative Site-specific Recombination and Phase Variation

6.7K
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

7.7K
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...

Variation of Atmospheric Pressure01:18

Variation of Atmospheric Pressure

4.1K
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...

Area of Science:

  • Microbiology
  • Environmental Science
  • Public Health

Background:

  • Hospital-acquired infections pose a significant public health threat.
  • Emerging sequencing technologies enable detailed characterization of microbial communities.

Purpose of the Study:

  • To characterize the hospital microbiome of surfaces in Cairo, Egypt, using omics technologies.
  • To identify bacterial communities on bed sheets and door knobs and screen for resistant microbes and genes.

Main Methods:

  • Screening of hospital surfaces, focusing on bed sheets and door knobs.
  • Utilizing sequencing technologies for unbiased identification of bacterial communities.
  • Screening for antibiotic resistance genes, including mobile beta-lactamase genes.

Main Results:

  • Bacterial communities on door knobs were richer and more diverse than on bed sheets.
  • Door knob bacteria included dust/debris-associated and skin-associated genera (e.g., Bacillus, Staphylococcus).
  • An expanded mobile beta-lactamase-encoding gene (bla) was detected, indicating global spread.

Conclusions:

  • Hospital surfaces harbor distinct microbial communities that can inform infection control.
  • Findings emphasize the importance of the emerging hospital microbiome research field.
  • Results can guide future infection control strategies in healthcare settings.
