Bleeding in Fresh Concrete01:22

Bleeding in Fresh Concrete

578
Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...

Gene Therapy00:59

Gene Therapy

27.6K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Amino acids03:42

Amino acids

105.4K
Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

Polyprotic Acids03:38

Polyprotic Acids

32.0K
Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:

Area of Science:

  • Bariatric Surgery
  • Surgical Hemorrhage Management

Background:

  • Postoperative bleeding from enteric staple lines is a known complication of bariatric surgery.
  • Reoperation for hemostasis is sometimes necessary, occurring in up to 2.5% of cases.
  • Conservative therapy with tranexamic acid for postoperative hemorrhage is a novel approach.

Purpose of the Study:

  • To evaluate the efficacy of tranexamic acid in reducing reoperation rates for postoperative bleeding after bariatric surgery.
  • To assess the rate of thrombo-embolic complications associated with tranexamic acid use in this patient population.

Main Methods:

  • Retrospective review of 1388 patients undergoing bariatric surgery (gastric bypass or sleeve gastrectomy).
  • Analysis of tranexamic acid administration, reoperation rates, transfusion rates, and thrombo-embolic complications.

Main Results:

  • Significant hemorrhage occurred in 3.2% of patients (45/1388).
  • Tranexamic acid was administered to 44 patients, with treatment failure in 4 cases.
  • The overall reoperation rate was 0.4%, and no thrombo-embolic complications were observed.

Conclusions:

  • Tranexamic acid administration appears safe and effective in reducing the need for reoperation due to bleeding after bariatric procedures.
  • The findings support tranexamic acid as a valuable tool for managing postoperative hemorrhage in bariatric surgery.
