Techniques of incorporation of salty compounds, food matrix, and sodium behaviour and its effect over saltiness perception: an overview.

The salty taste is usually associated with the positively charged ion sodium present in sodium chloride. Due to its relevance in the food industry, there have been several studies to determine how this ion behaves in various food matrices, or the use of techniques to improve saltiness perception to reduce the amount necessary for savoury food. Several databases were searched, and it was discovered that sodium can interact with the protein, modifying its mobility, as well as, other components of the food matrix, such as fat, that seem to interfere with saltiness perception, increasing or reducing it. Several techniques were used to identify the interaction between sodium and the food matrix, as well as sensory testing to determine the influence of different modification strategies to enhance the saltiness perception. Due to the multiple factors involved in the salty taste, understanding the effect of the technique to modify saltiness perception, the interaction of the matrix components of the food, and the sodium interaction with those components, can be of use in the developing process of foods with a reduction in the sodium content.

Partnering With Patients to Reduce Firearm-Related Death and Injury.

In the United States, nearly 40,000 deaths per year are firearm related. Among these fatalities are approximately 1300 children. In addition, there are more than 20,000 unintentional firearm injuries per year. Osteopathic physicians have a unique opportunity to affect this public health concern through patient education. Several evidenced-based recommendations can be incorporated at the bedside to reduce firearm injuries and deaths, including gun education, safe storage, and proper disposal.

Adverse Neuropsychiatric Events and Recreational Use of Efavirenz and Other HIV-1 Antiretroviral Drugs.

Efavirenz is a highly effective HIV-1 antiretroviral; however, it is also frequently associated with neuropsychiatric adverse events (NPAE) that include abnormal dreams, sleep disturbances, nervousness, anxiety, depression, and dizziness. The incidence of NPAEs upon initiation of treatment with efavirenz-containing medications is high, exceeding 50% in most studies. Although the NPAEs tend to decrease after the first month in many patients, they persist for long periods of time in others. Efavirenz-based treatment is generally well-tolerated in children, although some experience persistent concentration problems, as well as sleep disturbances, psychotic reactions, and seizures. In an effort to link basic with clinical research, parameters associated with efavirenz brain exposure are discussed, and factors that increase efavirenz levels are explored in depth as they are expected to contribute to NPAE risk. These include the role of modifiable and nonmodifiable risk factors such as diet, weight, and drug-drug interactions and sex, age, and ethnicity/pharmacogenetics. In addition to NPAEs, this review explores what is known about antiretroviral (ARV) drugs being used for recreational purposes. Although multiple ARV drugs are covered, special attention is devoted to efavirenz given that the majority of reports of NPAEs and illicit use of ARV drugs concern efavirenz. The evolving molecular mechanistic basis of NPAEs and abuse of efavirenz point to a complex and polymodal receptor pharmacology. Animal studies to date primarily point to a serotonergic mechanism of action. Recently emerging associations between HIV-associated neurocognitive disorder and efavirenz use, and possible contributions of the mitochondrial-immune-inflammatory-redox cascade are explored in the context of the signaling mechanisms that appear to be involved.
