OBJECTIVE: The pharmacological effects of generic (GE) donepezil are the same as Aricept, its brand-name counterpart. However, little is known as to whether these two drugs provide the same quality of life (QOL). The study subjects were patients with Alzheimer's disease who were taking donepezil hydrochloride tablets, and were selected by visiting either the local pharmacies or the patients' homes. We chose the brand-name drug Aricept and its GE form donepezil to investigate, from a long-term caregiver's perspective, the influence of both drugs on the patients' QOL. METHODS: An EuroQol-5 Dimension (EQ-5D) was used to assess the QOL of patients with Alzheimer's disease, before and after various Aricept and/or donepezil regimens. Patients were divided into four groups: first time users of Aricept (n=43), first time users of GE donepezil (n=45), users refilling previous prescriptions of Aricept (n=51), and users switching from Aricept to GE donepezil (n=51). RESULTS: The average change in the EQ-5D utility indices rose significantly in the patients starting a new regimen of Aricept and its GE drug. The patients continuing an existing regimen of Aricept showed no significant differences, even after Aricept was switched to a GE drug. CONCLUSION: The QOL of patients starting a new regimen of Aricept and its GE drug improved. The QOL was maintained upon switching to the GE drug form.

First, this article provides a brief overview of the previous hypotheses regarding depression and then focuses on involvement of genetic and environmental factors in development of depression. According to epidemiological research, 30~40% of occurrences of bipolar disorder involve a genetic factor. Therefore, environmental factors play a more important role in development of depression. Resilience and resistance to stress are common; therefore, although a certain extent of stress might be received during the embryonic or perinatal period, having a genetic predisposition to mental disorders does not imply that a mental disorder will develop. However, having a genetic predisposition to disorders does weaken resistance to stresses received during puberty, and without the ability to recover, a mental disorder is triggered. The importance of epigenetics in maintaining normal development and biology is reflected by the observation that development of many diseases occurs when the wrong type of epigenetic marks are introduced or are added at the wrong time or in the wrong place. Involvement of genetic and environmental factors in the onset of depression was investigated in relation to epigenetics. When mice with the disrupted in schizophrenia 1 (DISC1) abnormal gene received isolated rearing stress, depression-like abnormal behaviors and decreased gene expression of tyrosine hydroxylase in the frontal cortex by epigenetical suppression via DNA methylation were observed. Decrease of dopamine in the frontal cortex triggers behavioral disorders. Administration of a glucocorticoid receptor antagonist resulted in full recovery from neurological and behavioral disorders. These results suggest a new therapeutic approach to depression.

BACKGROUND: It has been recognized that a defect in klotho gene expression accelerates the degeneration of multiple age-sensitive traits. Accumulating evidence indicates that aging is associated with declines in cognitive function and the activity of growth hormone (GH)/insulin-like growth factor-1 (IGF-1). METHODS: In this study, we examined whether a GH-releaser diet could be effective in protecting against cognitive impairment in klotho mutant mice. RESULTS: The GH-releaser diet significantly induced the expression of IGF-1 and IGF-1 receptors in the hippocampus of klotho mutant mice. Klotho mutant mice showed significant memory impairments as compared with wild-type mice. In addition, the klotho mutation significantly decreased the expression of cell survival/antiapoptotic factors, including phospho-Akt (p-Akt)/phospho-glycogen synthase kinase3beta (p-GSK3beta), phospho-extracellular signal-related kinase (p-ERK), and Bcl-2, but significantly increased those of cell death/proapoptotic factors, such as phospho-c-jun N-terminal kinase (p-JNK), Bax, and cleaved caspase-3 in the hippocampus. Treatment with GH-releaser diet significantly attenuated both decreases in the expression of cell survival/antiapoptotic factors and increases in the expression of cell death/proapoptotic factors in the hippocampus of klotho mutant mice. In addition, klotho mutation-induced oxidative stress was significantly attenuated by the GH-releaser diet. Consequently, a GH-releaser diet significantly improved memory function in the klotho mutant mice. GH-releaser diet-mediated actions were significantly reversed by JB-1, an IGF-1 receptor antagonist. CONCLUSION: The results suggest that a GH-releaser diet attenuates oxidative stress, proapoptotic changes and consequent dysfunction in klotho mutant mice by promoting IGF-1 expression and IGF-1 receptor activation.

Introduction: We report a case of intractable nausea of a terminal malignant lymphoma patient with diabetes, which improved by sublingual administration of asenapine. Case: A 78-year-old man suffering from diffuse large B-cell lymphoma with diabetes presented intractable nausea and vomiting. Those symptoms were thought to be due to masses and nodules in the right frontal lobe and the cerebellum, and/or due to edema in the peripheral brain parenchyma. Because it was difficult to take medicines orally, we selected injections to control those symptoms. However, the combination of metoclopramide, haloperidol, and hydroxyzine injections failed to relieve nausea. Olanzapine is effective against nausea but is contraindicated for diabetic patients, so asenapine, one of the multi-acting receptor-targeted antipsychotics the same as olanzapine, was expected alternatively. The patient was administrated asenapine sublingually 5mg once a day before bedtime. This administration of asenapine remarkably improved his nausea. Discussion: Sublingual asenapine dose may be an effective therapeutic option for intractable nausea.
