Silver sulfadiazine

Silver sulfadiazine (INN, or silvadene) is a topical sulfonamide/silverantibacterial used as a topical cream on burns. Evidence regarding its usefulness in burns is poor. Tentative evidence has found that silver sulfadiazine may increase healing times – wounds may take longer to heal if treated with this drug, so it is not recommended by the authors of a Cochrane review.

Silver sulfadiazine is typically delivered in a cream or aqueous suspension.

It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system.

Medical uses

Evidence regarding its usefulness in burns is poor. A 2012 review found that topical silver may worsen healing time compared to controls and showed no evidence of effectiveness in preventing wound infection. A Cochrane systematic review from 2013 found that most of the trials had methodological shortcomings and thus are of little use. Another Cochrane systematic review from 2010 concluded, "There is insufficient evidence to establish whether silver-containing dressings or topical agents promote wound healing or prevent wound infection". Other reviews of the evidence have also concluded, "[the] quality of the trials was limited". Cochrane has raised concerns about delays in time to wound healing when SSD is used.

Motivation

Motivation is a theoretical construct used to explain behavior. It represents the reasons for people's actions, desires, and needs. Motivation can also be defined as one's direction to behavior, or what causes a person to want to repeat a behavior and vice versa. A motive is what prompts the person to act in a certain way, or at least develop an inclination for specific behavior. According to Maehr and Meyer, "Motivation is a word that is part of the popular culture as few other psychological concepts are".

Types of theories and models

Motivation theories can be classified on a number of bases.

Psychological theories and models

Motivation can be conceived of as a cycle in which thoughts influence behaviors, behaviors drive performance, performance impacts thoughts, and the cycle begins again. Each stage of the cycle is composed of many dimensions including attitudes, beliefs, intentions, effort, and withdrawal which can all affect the motivation that an individual experiences.
