Major depression case example

Among recent examples that highlight the synthetic utility of transition metal-catalyzed hydroborations are its direction toward a formal syntheses of the non-steroidal anti-inflammatory agents Ibuprofen 131 and Naproxen 13214 15 139 as well as the anti-depressant Sertraline 133 (Figure 14).140 In the majority of cases, rhodium-catalyzed hydroboration is utilized and the rhodium(i) source generally is Wilkinson s catalyst RhCl(PPh3)3. 

To make the discussion of LCA more concrete, consider an example. Assume we are investigating depression and conjecture three classes indi-viduals with major depression, individuals with dysthymia, and individuals with no depression. After the number of classes has been posited, we can define a mathematical model that links parameters of the latent classes (e.g., base rates) to proportions of cases in each cell of the cross-tabulation. LCA imposes this model on the data set and estimates parameters of the latent classes. This estimation is an iterative process. In the beginning, the investigator provides initial values for each parameter, to get the computation started somewhere. Initial values can be based on a completely unsubstantiated guess. Inaccurate guesses should not prevent LCA from eventually recovering the correct values. An accurate guess, however, would shorten the computation time. 

Classic reactive depressions (sometimes referred to as psychological depressions) can range in intensity from mild or moderate (for example, adjustment disorders with depressed mood) to severe (major depression). These disorders occur in response to identifiable psychosocial stressors. These stressors may be acute and intense (such as loss of a loved one), insidious (as in the case of a gradual deterioration in the quality of marital relationship), or in the distant past (for example, the emotions experienced by a survivor of child abuse who in adulthood begins to recall long-forgotten abusive events). 

The following case, excerpted from Spitzer ct al. (1989), is an example of major depression rated as moderately severe. 

In some cases, the pharmacology of the variants has not been fully characterized. For example, while the 524C>A, Leul33Ile CB2 variant has been associated with bipolar disorder, the pharmacological consequences of the variant are not fully unknown [306], By contrast, the CB2 variant, 315A>G, has been associated with major depression (MD) in Japanese population by [307]. 

In addition, it exerts beneficial effects in many disorders as an adjuvant to other treatment modalities. Such effects are apparent only if it is administered to an already pharmacologically treated patient. For example, in unresponsive major depressive disorder, the co-administration of lithium to an ongoing antidepressant treatment increases the response rate by up to 50%. In most cases, the response to lithium augmentation is either considerable or not at all ( all-or-none phenomenon). Some (currently not convincing) results have also been reported in unipolar depression, bulimia nervosa, and attention deficit hyperactivity disorder (ADHD). Lithium also exerts antiaggressive effects in conduct disorder, independent of any mood disorder, and can reduce behavioral dyscontrol and self-mutilation in mentally retarded patients. One of the most striking effects of lithium is its antisuicidal effect in patients who suffer from bipolar and unipolar depressive disorder irrespective of comorbid axis I disorder. ... 

In the case of duloxetme, a benzene ring has been replaced by a thiophene nucleus which is a commonly used approach during the process of lead modification. The number of atoms is not the same hence it may be described as a non-classical isostere The phenoxy group has also been transformed, which provides an example of a ring fusion, resulting in the presence of a naphthalenyl-oxy group. This dmg is non-selective, which makes it a mixed SERT/NAT inhibitor. It is indicated for the treatment of major depression, diabetic neuropathy and urinary incontinence. Duloxetine is used as the (S)-enantiomer hydrochloride salt and is available as capsules (30 mg). A typical adult daily dose for the treatment of major depression and diabetic neuropathy is 60 mg. In case of urinary incontinence, 40 mg twice daily have been recommended. 

Perhaps the most depressing fact associated with the consequences of the above division is the lack of consistency often found in treatments of compounds which are essentially isostructural. Take, for instance, the different descriptions of the bonding situation in B2H6 on the one hand, and the isostructural (e.g. AI2CI6) molecules on the other while the latter may be treated by the conventional bonding principles expressed in Hyps. III.l to III.5, the treatment of the former (in terms of 3-centre bonds) breaks with Hyps. III.l to III.4. A similar conclusion is in fact reached in the majority of abnormal cases. Other simple examples are provided by the alkali-metal hydrides (with NaCl-type structure), CuH (with ZnS-wurtzite type structure), etc. These examples are typical in that it is only when a scarcity of electrons and/or orbitals enforces a search for extraordinary bonding principles that Hyps. III.l to III.4 are reluctantly (partly or completely) replaced by alter-... 

Two major problems complicating the question of treatment-resistant depression are inappropriate diagnosis and inadequate treatment (355). Studies have found only a small proportion (< 15%) of newly diagnosed depressed patients receive adequate antidepressant treatment as defined by dose and duration criteria (356, 357). Hence, a substantial number of treatment-resistant cases are actually the result of inadequate therapy (i.e., relative resistance). For example, in the MacEwan and Remick (358) study, 70% of those defined as treatment-unresponsive achieved complete remission with an adequate trial of an HCA, MAOl, or ECT. Patients who do not receive sufficient benefit from a trial of one antidepressant now have the option of newer agents whose activity does not necessarily overlap with earlier generation compounds (e.g., SSRIs, venlafaxine, nefazodone). 

Other CYP3A4 inducers have also been reported to exert a pronounced effect on oral midazolam AUC (78), presumably through induction of intestinal and hepatic CYP3A4. For example, administration of phenytoin and carba-mazepine led to a 94% reduction in midazolam AUC compared with an untreated control population. Induction of CYP3A by St. John s wort, a widely used herbal supplement for the treatment of mild to moderate depression, has also attracted considerable interest. The major bioactive ingredient of St. John s wort, hyperforin, is a very potent in vitro activator of hPXR (79,80). Several groups have investigated induction of midazolam clearance by St. John s wort (81-83). As in the case of rifampin, clearance of oral midazolam... 

Altered consciousness is a major adverse effect of baclofen, because of its GABA-mimetic effects. While this reflects global nervous system depression, other adverse effects, such as seizures and dyskinesias, are probably better explained by selective effects on different brain areas. A case of akinetic mutism associated with baclofen might be an example of this (1).
