Modified-Release Drug Delivery Systems: Rate-Programmed II01:19

Modified-Release Drug Delivery Systems: Rate-Programmed II

4
Rate-programmed drug delivery systems release drugs in a controlled manner to maintain therapeutic levels. Three main designs include reservoir, matrix, and hybrid systems.Reservoir systems consist of a drug core enclosed within a membrane that controls drug release. In non-swelling reservoir systems, polymers like ethyl cellulose or polymethacrylates are used. These do not hydrate in aqueous media and control release through membrane thickness, porosity, or insolubility. This type includes...

Modified-Release Drug Delivery Systems: Rate-Programmed I

17
Rate-programmed drug delivery systems (DDS) are designed to release drugs at specific, controlled rates to maintain consistent therapeutic levels. These systems are categorized based on their release mechanisms, including dissolution-controlled DDS, diffusion-controlled DDS, and combined dissolution-diffusion-controlled DDS.In dissolution-controlled DDS, the release rate depends on the slow dissolution of the drug itself or the surrounding matrix. Drugs with inherently slow dissolution rates,...

Genetic Screens02:46

Genetic Screens

5.8K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Assessment of the Mouth01:26

Assessment of the Mouth

1.2K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Assessment of Respiration01:23

Assessment of Respiration

2.0K
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

Nursing Assessment01:29

Nursing Assessment

The two sources for collecting information are primary and secondary. After gathering information, interpretation and validation help to complete the data. The purpose of assessment is to establish data with the initial information, to interpret data about the patient's perceived needs and health problems, and to respond to these problems identified.
The nurse collects all aspects of the patient's health in the initial assessment, establishing priorities for ongoing focused assessments...

Area of Science:

  • Medical Genetics
  • Public Health
  • Neonatal Screening

Background:

  • Phenylketonuria (PKU) is a critical autosomal recessive metabolic disorder.
  • Untreated PKU leads to severe, irreversible neurological damage and cognitive impairment.
  • Effective screening programs are vital for early detection and intervention in children.

Purpose of the Study:

  • To assess the quality and effectiveness of the phenylketonuria screening program in Chaharmahal and Bakhtiari province.
  • To analyze the incidence, coverage, and key performance indicators of the PKU screening program.
  • To evaluate healthcare facilities, diagnosis/treatment timelines, and awareness levels related to PKU screening.

Main Methods:

  • A descriptive-analytic study design was employed.
  • Data collected from 2012 to 2015 using checklists for facilities and timelines.
  • Knowledge questionnaires assessed parental and staff awareness regarding phenylketonuria screening.

Main Results:

  • Cumulative PKU incidence was 1 in 6662 live births (2012-2015).
  • Program coverage reached 100%, with on-time sampling increasing from 80% (2012) to 84.6% (2015).
  • Sensitivity was 100%, specificity 99.9%, and all treatments initiated within 4 weeks; staff awareness was fair, but parental awareness was not impacted.

Conclusions:

  • The phenylketonuria screening program in the province is of appropriate general quality.
  • High sensitivity and specificity indicate effective detection and timely treatment initiation.
  • Recommendations include enhancing staff and parental awareness and supervision for improved outcomes.
