An investigation of the feasibility of predicting outcome indices in the treatment of heroid addiction

An exploratory study employing multiple linear regression techniques was conducted to investigate the feasibility of predicting outcome indices in the treatment of heroin addiction. Demographic and biographic intake variables were obtained for heroin addicts prior to treatment in one of two different types of residential treatment programs. Length of treatment, further categorized into "split-stay" categories, was chosen as the criterion because of its importance from the standpoint of program management. Subsequent stepwise regression procedures resulted in 11 variables of sufficient predictability to account for approximately 30% of the variability in the split-stay criterion. The employment of the derived equation resulted in correct classification in approximately 75% of the cases. This was beyond what could have been predicted by chance alone or from the knowledge of the observed split-stay ratio. A clear demonstration of the feasibility of the model was obtained; however, as to its utility, implementation in the actual treatment setting would be required. Implications for the use of this type of prediction model were discussed.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.
