Objective:

The purpose of this scoping review was to determine the inclusion and exclusion criteria typically used for human participants when conducting occupational vocal function research.

Methods:

A scoping review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines searching PubMed/MEDLINE (Ovid), APA PsychInfo, and Web of Science with a cover period between January 1, 2018 and September 15, 2023. Studies performed on human participants and published in English were included in this study. In addition, studies were required to use human participants (all ages and sexes) who were occupational voice users. Articles using the following study designs were included: experimental (randomized controlled trials, quasi-experimental) and nonexperimental (observational, cross-sectional). Review articles, case reports, editorials, meta-analysis, and opinion pieces were excluded from review, as well as studies that included participants with head and neck cancer.

Results:

A total of 71 studies were included in this scoping review. Data extraction and analysis revealed that variables of sex and vocal health were consistently accounted for in research; however, inclusion/exclusion variables such as gender, hydration, and medication use were rarely included.

Conclusion:

This scoping review highlights the need to consider more expansive inclusion/exclusion criteria as relates to factors that could impact objective measures of vocal function. Moreover, developing consistent inclusion and exclusion criteria across studies may help clinicians generalize findings to clinical populations.

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Bias in Epidemiological Studies

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Respiratory Assessment: Purpose and Indications

Respiratory Assessment: Purpose and Indications

Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
