Secondary Active Transport01:55

Secondary Active Transport

138.1K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Secondary Healthcare System

2.1K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...

Data Reporting and Recording

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Primary and Secondary Growth in Roots and Shoots

60.6K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Secondary Distribution01:25

Secondary Distribution

582
Secondary distribution systems provide electrical energy at the utilization voltage levels from distribution transformers to customer meters. Typical secondary voltages in the United States include 120/240 V for residential use, 208Y/120 V for residential and commercial use, and 480Y/277 V for industrial and high-rise commercial use.
In residential areas, 120/240 V single-phase, three-wire service is commonly used for lighting, outlets, and large appliances. Urban areas with high-density loads...

Area of Science:

  • Health Services Research
  • Digital Health
  • Health Informatics

Background:

  • Internet use is increasingly recognized for its potential to empower patients and manage health system costs.
  • Evidence linking internet use to health outcomes and service utilization is limited due to data constraints.
  • Existing research often lacks the scale to investigate these relationships comprehensively.

Purpose of the Study:

  • To present a novel approach for linking disparate datasets to analyze the relationship between internet use and health.
  • To utilize spatial microsimulation to connect internet use survey data with census and health system data.
  • To examine how internet access, support, and usage correlate with perceived health and health service utilization.

Main Methods:

  • Spatial microsimulation was employed to integrate a random sample survey on internet use with aggregate census data.
  • Routine health system data was combined with survey data at small geographic area levels.
  • The study linked datasets using geographic location as the common element for joint analysis.

Main Results:

  • Internet use demonstrated a significant association with higher perceived health.
  • Increased internet use correlated with decreased health service utilization, irrespective of access, support, or usage metrics.
  • Statistical validation confirmed the accuracy and reliability of the simulated dataset.

Conclusions:

  • Spatial microsimulation provides a privacy-preserving and cost-effective method for generating new insights by linking secondary data.
  • This approach enhances the understanding of the internet use-health relationship, offering valuable theoretical and practical implications for policy.
  • The methodology allows for granular, local-level insights into digital health disparities and interventions.
