Teratogenicity01:07

Teratogenicity

2.5K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Preventive Healthcare Services

1.1K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Nursing Diagnosis01:22

Nursing Diagnosis

2.8K
Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.
The nursing diagnosis focuses on evidence-based...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions

2.2K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:

Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

2.5K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Formulating and Validating Nursing Diagnosis II01:25

Formulating and Validating Nursing Diagnosis II

2.9K
Nursing diagnoses represent a problem validated by major defining characteristics. There are four categories of nursing diagnoses: problem-focused, risk, health promotion or wellness, and syndrome. The anatomy of a nursing diagnosis includes three components: problem statement or diagnostic label, defining characteristics, and related factors.
Risk nursing diagnoses represent clinical judgments of an individual, family, or community more vulnerable to developing the health problem than others...

Summary
This summary is machine-generated.

Fetal upper tract urinary system dilation can indicate lower urinary tract obstruction (LUTO), a serious condition. Prenatal treatments like shunts exist but carry significant risks requiring careful consideration.

Area of Science:

  • Urology
  • Prenatal diagnostics
  • Fetal medicine

Background:

  • Fetal upper tract urinary system dilation is a common prenatal ultrasonography finding.
  • Posterior urethral valves are the main cause of fetal lower urinary tract obstruction (LUTO).
  • LUTO is a critical diagnosis impacting fetal management and pregnancy course.

Purpose of the Study:

  • To review the diagnosis and management of fetal lower urinary tract obstruction.
  • To discuss available prenatal treatment options for LUTO.
  • To highlight the risks associated with fetal interventions for LUTO.

Main Methods:

  • Review of current literature on fetal lower urinary tract obstruction.
  • Analysis of diagnostic findings in prenatal ultrasonography.
  • Evaluation of prenatal treatment modalities for LUTO.

Main Results:

  • Fetal upper tract urinary system dilation is frequently observed.
  • Posterior urethral valves represent the primary etiology of LUTO.
  • Prenatal interventions for LUTO include observation, shunt placement, amnioinfusion, and direct valve treatment.

Conclusions:

  • LUTO is a severe fetal urologic diagnosis with significant implications.
  • Prenatal treatment options for LUTO are available but involve substantial risks.
  • Careful consideration and counseling are essential for all fetal interventions in LUTO cases.
