Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic01:26

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

5.5K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Hypertension I: Introduction01:28

Hypertension I: Introduction

879
Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Hypertension II: Pathophysiology01:29

Hypertension II: Pathophysiology

944
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Hypertension V: Nursing Management

433
The nursing management of hypertension involves accurately assessing symptoms, making a comprehensive nursing diagnosis, collaborating with patients to set goals, and implementing targeted interventions to mitigate the condition's impact and improve patient well-being.Comprehensive AssessmentThe initial step in nursing care for hypertension involves a thorough patient assessment. It includes evaluating symptoms such as headaches, dizziness, blurred vision, and previous hypertension episodes.

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

4.3K
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Pulmonary Hypertension: Classification and Pathogenesis

645
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Area of Science:

  • Pharmacology
  • Genetics
  • Cardiovascular Medicine

Background:

  • Numerous medications can disrupt blood pressure (BP) regulation, leading to adverse effects.
  • Understanding the mechanisms behind drug-induced hypertension (HTN) is crucial for patient safety.

Purpose of the Study:

  • To investigate the molecular targets of drugs causing iatrogenic hypertension (HTN).
  • To identify shared gene targets between HTN-indicated and HTN-inducing drugs.
  • To elucidate mechanisms of drug-induced HTN for developing safer therapeutics.

Main Methods:

  • Bioinformatic analysis of databases (SIDER, DrugBank, Genomatix) for HTN-associated drug targets.
  • Construction of an interaction map of 198 human genes involved in BP regulation.
  • Investigation of 72 HTN-indicated and 160 HTN-inducing drugs.

Main Results:

  • HTN-indicated drugs impact multiple functional subsystems of BP regulation, particularly adrenergic and dopaminergic pathways.
  • A significant overlap of 25 shared gene targets was found between HTN-indicated and HTN-inducing drugs.
  • Six drug families not indicated for HTN were identified as major causes of BP side effects.

Conclusions:

  • Drug-induced hypertension involves complex interactions with BP regulatory systems.
  • Shared molecular targets highlight potential risks and therapeutic opportunities.
  • This research supports the development of personalized medicine with reduced adverse cardiovascular effects.
