Pancreatic cancer and depression: myth and truth

<p>Abstract</p> <p>Background</p> <p>Various studies reported remarkable high incidence rates of depression in cancer patients compared with the general population. Pancreatic cancer is still one of the malignancies with the worst prognosis and therefore it seems quite logical that it is one of the malignancies with the highest incidence rates of major depression.</p> <p>However, what about the scientific background of this relationship? Is depression in patients suffering from pancreatic cancer just due to the confrontation with a life threatening disease and its somatic symptoms or is depression in this particular group of patients a feature of pancreatic cancer per se?</p> <p>Discussion</p> <p>Several studies provide evidence of depression to precede the diagnosis of pancreatic cancer and some studies even blame it for its detrimental influence on survival. The immense impact of emotional distress on quality of life of cancer patients enhances the need for its early diagnosis and adequate treatment. Knowledge about underlying pathophysiological mechanisms is required to provide the optimal therapy.</p> <p>Summary</p> <p>A review of the literature on this issue should reveal which are the facts and what is myth.</p

Are serum lipid and lipoprotein levels related to dementia?

Although hyperlipidemia is known to contribute to vascular disease and it may play a role in dementia, specific studies for elderly are limited. The aim of this study is to examine the relationship between dyslipidemia and dementia. In this study, 1251 patients admitted to the Hacettepe University Division of Geriatric Medicine were enrolled. On the basis of the mini mental state examination (MMSE), the clock drawing test (CDT) scores, the APA DSM-IV and the NINCDS-ADRDA criteria and the Hachinski ischernic score (HIS), the subjects were divided into four groups: Alzheimer's disease (AD), vascular dementia (VD), mild cognitive impairment (MCI) and normal cognitive status (NCS). The lipoprotein levels were measured, and we analyzed the data Using chi(2) and the one-way analysis of variance methods. Among the Subjects, 14.8% had low high-density lipoproteins (HDL), 58.5% had high triglyceride (TG), 73.6% had high low-density lipoproteins (LDL), and 21.6% had high lipoprotein-a (Lp(a)) Of Our Study Population. There was no difference between the dementia subgroups and the NCS group in the lipoprotein levels. The only significant relationship was between high TG levels and the AD, as well as the MCI groups. Low HDL and high LDL are important problems in elderly. Although serum lipid levels, especially of Lp(a), has recently been thought to be related with dementia, our study suggests the absence of such a relationship. The national data regarding the elderly population should be evaluated on the basis of genetic and environmenta

Depression and concomitant diseases in a Turkish geriatric outpatient setting

Depression is an important but inadequately diagnosed mood disorder ill elderly. Depressed elderly patients often have chronic concomitant diseases. This paper intended to determine the prevalence of depression and its relation with concomitant disorders and social status among the patients admitted to our geriatric unit. Seven hundred and eighty-nine females and 466 males admitted to our unit were examined for the presence of depression by using the geriatric depression scale (GDS) test. The presence of concomitant diseases was assessed. Depression was diagnosed in 273 patients (21.8%), 193 (70.7%) females and 80 (29.3%) males. Depressed patients suffered from a wide range of other diseases the number and prevalence of which were as follows: Alzheimer's disease (AD) (34; 12.5%), vascular dementia (27; 9.9%), hypertension (HT) (211; 77.3%), diabetes mellitus (DM) (64; 23.4%). osteoporosis (182; 66.7%), atherosclerotic coronary artery disease (CAD) (89; 32.6%), cardiac failure (23; 8.5%), bronchial asthma (8; 2.9%), chronic obstructive pulmonary disease (COPD) (25; 9.2%) and osteoarthritis (133; 48.8%). The correlation between depression and concomitant diseases was statistically significant in hypertensive, demented and osteoporotic patients, as determined in a large elderly population. Previous studies examined the correlation of depression with only one concomitant disease, while we performed the analysis on multiple correlations. (c) 2004 Elsevier Ireland Ltd.

Psychiatric morbidity, quality of life, and disability in mesial temporal lobe epilepsy patients before and after anterior temporal lobectomy

Considerable interest has been focused on the psychiatric complications of medically refractory temporal lobe epilepsy (TLE) before and after epilepsy surgery. The aim of the present study was to evaluate the psychiatric status, quality of life, and level of disability in medically refractory mesial temporal lobe epilepsy (MTLE) patients, a homogenous subgroup of patients with TLE, before and after anterior temporal lobectomy (ATL). The study population consisted of 22 patients with medically refractory MTLE who were candidates for ATL. Patients were examined before surgery as well as in the third and sixth months of the postoperative period. Psychiatric diagnosis was determined by using SCID-I. to rate the severity of psychiatric disorders, BPRS, HDRS, and HARS were employed on each visit. WHO-DAS-II and WHOQOL-BREF were used to determine the level of disability and quality of life. Preoperatively, six patients had a psychiatric diagnosis. Three months after surgery, six of the patients had psychiatric diagnoses. Five of these six patients had not been previously diagnosed. There was no significant difference between preoperative and postoperative follow-up evaluations in terms of HDRS, HARS, and BPRS ratings. With respect to the total scores and domains of WHO-DAS-II, the change in pre- and postoperative evaluations was statistically significant only for the social life attendance domain. There was no significant difference in the mean scores on the WHOQOL-BREF domains or on the first question about general evaluation of quality of life. For the second question on the level of satisfaction with health, the difference between the three ratings was statistically significant. Preoperative and postoperative rates of psychiatric disorders in our sample were low. While social phobia was frequently seen preoperatively, the postoperative period was spearheaded by major depressive disorder. The decrease in disability in attendance to social life and improvement in the quality of health were in concordance with the literature, indicating the positive results of surgical treatment of epilepsy on quality of life. This study suggests that surgical intervention might be one of the causes of postoperative psychiatric disorders in patients with MTLE. (c) 2005 Elsevier Inc. All rights reserved

New directions in therapeutics for Huntington disease

Huntington disease (HD) is an autosomal dominantly inherited neurodegenerative disease that affects motor, cognitive and psychiatric functions, and ultimately leads to death. The pathology of the disease is based on an expansion of CAG repeats in exon 1 of the huntingtin gene on chromosome 4, which produces a mutant huntingtin protein (mHtt). This protein is involved in neurotoxicity and brain atrophy, and can form β-sheets and abnormal mHtt aggregates. Currently, there are no approved effective treatments for HD, although tetrabenazine (Xenazine™) and deutetrabenazine (AUSTEDO™) have been approved for treatment of the motor symptom chorea in HD. This literature review aims to address the latest research on promising therapeutics based on influencing the hypothesized pathological mechanisms
