Quantitative Aspects of Drug-Receptor Interaction01:30

Quantitative Aspects of Drug-Receptor Interaction

1.8K
The receptor occupancy theory connects a drug's response to the number of occupied receptors. With higher drug concentrations, more receptors are occupied, leading to increased responses. The formation of drug-receptor complexes involves association and dissociation rates, which reach equilibrium when the forward and backward reactions are equal. The equilibrium association constant (Ka) and its inverse, the equilibrium dissociation constant (Kd), indicate drug affinity. Higher Ka and lower...

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Handwashing II: Pre-procedure and Initial Procedure Steps

1.6K
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail...

Hemodialysis II: Procedure and Complications

970
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Tracheostomy: Procedure and Tubes

3.6K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Summary

The Bentall procedure with biological valves shows acceptable long-term survival and better freedom from structural valve deterioration and reoperation. Modifications improve valve implantation and future reintervention options.

Area of Science:

  • Cardiovascular Surgery
  • Biomaterials Science
  • Geriatric Medicine

Background:

  • The Bentall procedure, utilizing biological valved conduits, is increasingly performed due to rising aortic valve disease in aging populations and its use in younger patients.
  • Long-term durability and the risk of structural valve deterioration (SVD) are primary concerns for the bio-Bentall procedure.

Purpose of the Study:

  • To review surgical outcomes of the bio-Bentall procedure at our institution.
  • To compare our results with existing literature, focusing on long-term survival, SVD, and reoperation rates.
  • To evaluate the utility of a modified double sewing ring technique.

Main Methods:

  • Retrospective review of bio-Bentall procedure cases at our hospital.
  • Inclusion of a comprehensive literature review on biological valved conduits in Bentall procedures.
  • Analysis of long-term survival, freedom from SVD, and reoperation rates.

Main Results:

  • Surgical outcomes demonstrate acceptable long-term survival compared to other studies.
  • Patients exhibited better freedom from structural valve deterioration (SVD) and reoperation rates than reported elsewhere.
  • No SVD complications were observed in our patient cohort.
  • The double sewing ring technique facilitated the implantation of larger valves, improved hemostasis, and simplified reoperation.

Conclusions:

  • The bio-Bentall procedure offers acceptable long-term survival with promising freedom from SVD and reoperation.
  • The modified double sewing ring technique enhances valve implantation and offers advantages for future interventions, including valve-in-valve procedures.
