Observational Studies01:11

Observational Studies

10.8K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Bioavailability Study Design: Absolute Versus Relative Bioavailability

327
Bioavailability is a crucial pharmacokinetic parameter that quantifies the proportion of an administered drug that reaches the systemic circulation and is available for therapeutic action. Regulatory agencies mandate the assessment of bioavailability, typically measured as the area under the drug plasma concentration-versus-time curve (AUC), to ensure the efficacy and safety of pharmaceutical products. These evaluations are categorized as absolute and relative bioavailability studies.Absolute...

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.

Naturalistic Observations

17.0K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

C–C Bond Cleavage: Retro-Aldol Reaction00:57

C–C Bond Cleavage: Retro-Aldol Reaction

7.5K
The reverse of the aldol addition reaction is called the retro-aldol reaction. Here, the carbon–carbon bond in the aldol product is cleaved under acidic or basic conditions to form two molecules of carbonyl compounds. The mechanism of the reaction consists of three steps.
In the first step, as depicted in Figure 1, the base deprotonates the β-hydroxy ketone at the hydroxyl group to form an alkoxide ion.

Relative Risk01:12

Relative Risk

2.0K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Area of Science:

  • Cardiorespiratory Medicine
  • Digital Health
  • Patient-Reported Outcomes

Background:

  • Breathlessness is a common symptom in cardiorespiratory diseases.
  • Physician assessment often relies on patient symptom recall.
  • The relationship between experienced and recalled breathlessness is not well understood.

Purpose of the Study:

  • To evaluate the relationship between experienced breathlessness and recalled breathlessness.
  • To assess the relationship between experienced breathlessness and predicted future breathlessness.
  • To investigate novel methods for collecting daily life symptom data.

Main Methods:

  • Utilizing a mobile phone application for daily data collection.
  • Recruiting medically stable adult participants with cardiorespiratory conditions.
  • Employing Numerical Rating Scale (NRS) for breathlessness intensity (0-10) and daily/weekly recall over one week.
  • Analyzing data using multivariable random effects regression models.

Main Results:

  • Results are pending publication in peer-reviewed journals.
  • Findings will be presented at relevant scientific conferences.
  • The study protocol is designed to yield significant insights into breathlessness perception.

Conclusions:

  • This study protocol outlines an innovative approach to understanding breathlessness.
  • It aims to bridge the gap between subjective patient experience and clinical assessment.
  • The findings are expected to enhance the management of cardiorespiratory conditions.
