Hospitals-II

1.2K
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...

Half-life of a Reaction02:42

Half-life of a Reaction

39.4K
The half-life of a reaction (t1/2) is the time required for one-half of a given amount of reactant to be consumed. In each succeeding half-life, half of the remaining concentration of the reactant is consumed. For example, during the decomposition of hydrogen peroxide, during the first half-life (from 0.00 hours to 6.00 hours), the concentration of H2O2 decreases from 1.000 M to 0.500 M. During the second half-life (from 6.00 hours to 12.00 hours), the concentration decreases from 0.500 M to...

Characteristics of Life

262.9K
Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

The Angiosperm Life Cycle02:39

The Angiosperm Life Cycle

73.0K
Plants have a life cycle split between two multicellular stages: a haploid stage—with cells containing one set of chromosomes—and a diploid stage—with cells containing two sets of chromosomes. The haploid stage is the gamete-producing gametophyte, and the diploid stage is the spore-producing sporophyte.

The Tree of Life - Bacteria, Archaea, Eukaryotes

39.2K
The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

Area of Science:

  • Clinical Medicine
  • Pharmacology
  • Public Health

Background:

  • Smoking remains a leading cause of preventable death.
  • Nicotine addiction poses a significant public health challenge.
  • Pharmacological interventions are crucial for smoking cessation.

Purpose of the Study:

  • To evaluate the real-world effectiveness and safety of varenicline.
  • To assess varenicline's efficacy in a hospital-based smoking cessation program.
  • To identify factors associated with treatment success or failure.

Main Methods:

  • A longitudinal prospective study of 310 smokers treated with varenicline.
  • Data collected from 2011 to 2021 at a hospital's Smoking Cessation Unit.
  • Abstinence rates assessed at 3, 6, and 12 months; adverse events recorded.

Main Results:

  • Achieved 3, 12-month abstinence rates of 51.3%, 40.0%, and 36.5% respectively.
  • Smoking first cigarette within 5 minutes of waking independently predicted treatment failure (OR: 2.516, p=0.02).
  • Adverse events occurred in 27% of patients, leading to discontinuation in 11%.

Conclusions:

  • Varenicline shows favorable real-world efficacy and safety for smoking cessation.
  • Treatment effectiveness was consistent across varying patient motivation and comorbidities.
  • Active follow-up is vital for optimizing adherence and long-term smoking cessation success.
