Depression studies

With respect to different depressant studies, only a limited amount of work has been performed with Quebracho, tanic acid and different lignin sulphonates. Lignon sulphonates with a medium molecular weight were superior. 

A series of studies demonstrates a synergistic effect between drug therapies and psychodynamic talk therapies. The effectiveness of each form of therapy used independently is less than their combined use in the case of major depression. See A. Solomon, The Noonday Demon An Atlas of Depression (New York Scribner s, 2001) E. Good, Chronic Depression Study Backs the Pairing of Therapy and Drugs, New York Times (May 18, 2000) L. Altshuler et al., Treatment of Depression in Women A Summary of the Expert Consensus Guidelines, of Psychiatric Practice 7 (May 2001) 185-208. Kleinman, Rethinking Psychiatry p. ii. 

So far, however, boundaries have not been established and, even worse, no systematic attempts to do so are noticed. This hampers biological psychiatry and may well be among the reasons that the search for biological markers of psychiatric disorders over the past 35 years has been remarkably unsuccessful. A concrete example may illustrate this point a score of at least 16-18 on the Hamilton Depression Scale (M. Hamilton 1960] is generally accepted as a criterion to include someone in a depression study. One could, however. 

A review of our safety data to date shows that 107 patients have been treated with inositol. Of these, 61 have had full chemistry and hematology before and after inositol. Only two patients, both in the depression study, showed any changes in blood chemistry. Both showed a mild increase in blood glucose that disappeared on repeat in one but continued in the other several weeks after discontinuation of inositol. Total side effects were flatus in four patients, nausea in one, sleepiness in two, and insomnia in two. These side effects were similar to those reported in the placebo group.

In an analysis of data from the National Institute of Mental Health Collaborative Depression Study in 643 patients with affective disorders who were followed up after fluoxetine was approved by the FDA in December 1987 for the treatment of depression, nearly 30% (n = 185) took fluoxetine at some point (18). There was an increased rate of suicide attempts before fluoxetine treatment in those who subsequently took fluoxetine. Relative to no treatment, fluoxetine and other antidepressants were associated with non-significant reductions in the likelihood of suicide attempts or completions. Severity of psychopathology was strongly associated with increased risk, and each suicide attempt after admission to the study was associated with a marginally significant increase in the risk of suicidal behavior. The authors concluded that the results did not support the speculation that fluoxetine increases the risk of suicide. 

Local medical and societal cultural factors impact on the ethics committee approvals, so that a study that is considered to be ethical in one country may be regarded as unethical in another. Examples of this may be the unacceptability of the use of placebo control in depression studies in Germany, whereas similar studies would be permitted elsewhere. Similarly, the common practice of extensive blood sampling in Belgium, especially in pediatric studies, would be regarded as excessive and hence unethical in other countries. 

In any case, there is a pressing need for a systematic study of adolescent depression, comparing psychotherapy or cognitive behavioral thereapy (CBT) and antidepressants, or the combination of both treatments. The National Institute of Mental Health (NIMH) has organized a multicenter study which will analyze the long-term effectiveness of Prozac versus CBT. Results of the study, called Treatment for Adolescent Depression Study (TADS), will not be published for several years, but it is hoped that the results will help resolve whether antidepressants in teens are beneficial and safe.

Depression. Studies of major depressive disorder have used H and P MRS to record metabolite levels in the brain. Jumum et al. found significantly reduced NAA, ml and Glu levels in the anterior cingulate cortex of patients compared with healthy controls. Wang et a/. found significantly lower NAA/tCr and Cho/tCr ratios in the left dorsolateral prefrontal white matter, and lower NAA/tCr ratios in the right dorsolateral prefrontal white matter compared with the control subjects. However, they... 

Under these circumstances AH cannot be obtained in any simple manner, when data is analyzed over the complete composition range. However, it can be determined if the limiting slope is established. The neglect of the entropic term in Eq. (3.13) can usually be justified by the small temperature range that is encompassed by experiment. The value of AH should be scarcely affected by the approximation introduced. However, the value of B may be. Hence, it should not be unexpected that it often does not agree with the values obtained by other methods. Melting point depression studies are not always accurate in determining thermodynamic interaction parameters between polymer and diluent.
