Cognitive decline and alcohol consumption in the aging population-A longitudinal analysis of the Survey of Health, Ageing and Retirement in Europe.

BACKGROUND: Prevalence of cognitive decline and dementia is rising globally, with more than 10 million new cases every year. These conditions cause a significant burden for individuals, their caregivers, and health care systems. As no causal treatment for dementia exists, prevention of cognitive decline is of utmost importance. Notably, alcohol is among the most significant modifiable risk factors for cognitive decline. METHODS: Longitudinal data across 15 years on 6,967 individuals of the Survey of Health, Ageing and Retirement in Europe were used to analyze the effect of alcohol consumption and further modifiable (i.e., smoking, depression, and educational obtainment) and non-modifiable risk factors (sex and age) on cognitive functioning (i.e., memory and verbal fluency). For this, a generalized estimating equation linear model was estimated for every cognitive test domain assessed. RESULTS: Consistent results were revealed in all three regression models: A nonlinear association between alcohol consumption and cognitive decline was found-moderate alcohol intake was associated with overall better global cognitive function than low or elevated alcohol consumption or complete abstinence. Furthermore, female sex and higher educational obtainment were associated with better cognitive function, whereas higher age and depression were associated with a decline in cognitive functioning. No significant association was found for smoking. CONCLUSION: Our data indicate that alcohol use is a relevant risk factor for cognitive decline in older adults. Furthermore, evidence-based therapeutic concepts to reduce alcohol consumption exist and should be of primary interest in prevention measures considering the aging European population.

Dysregulated Methylation Patterns in Exon IV of the Brain-Derived Neurotrophic Factor (BDNF) Gene in Nicotine Dependence and Changes in BDNF Plasma Levels During Smoking Cessation.

Introduction: Several studies reported dysregulated protein levels of brain-derived neurotrophic factor (BDNF) in smokers and during cessation. However, the epigenetic regulation of the BDNF gene has not yet been investigated. We measured the plasma levels of BDNF and the epigenetic regulation of exon IV of the BDNF gene in smokers compared to healthy controls over a cessation period of 14 days. Method: We measured BDNF plasma levels and BDNF promoter methylation in 49 smokers and 51 non-smokers at baseline, day 7, and day 14 of smoking cessation. Mean methylation levels of 11 Cytosine Guanosine dinucleotides of exon IV of the BDNF gene were determined via bisulfite sequencing. Results: BDNF plasma and methylation levels were significantly lower in healthy controls when compared with smokers across all time points. BDNF levels for smokers decreased significantly during the cessation period. Comparing the sexes, female smokers showed significantly lower plasma BDNF levels than healthy controls at baseline and over 14 days of cessation. Male and female smokers showed significantly higher mean methylation rates than non-smokers at baseline. In male smokers, mean methylation levels decreased significantly during the cessation period. Conclusion: Our findings replicate the findings of previous studies that BDNF plasma levels are altered in smokers. Furthermore, BDNF expression and gene methylation are altered during the first 14 days of cessation. Our novel findings of dysregulated methylation patterns in exon IV of the BDNF gene further support the thesis that BDNF plays a role in nicotine dependence.

Does thiamine protect the brain from iron overload and alcohol-related dementia?

Alcohol-related dementia (ARD) is a common and severe co-morbidity in alcohol use disorder (AUD). We propose brain iron overload (BIO) to be an important and previously neglected pathogenic process, accelerating cognitive decline in AUD. Furthermore, we suggest thiamine, which is frequently depleted in AUD, to be a key modulator in this process: Thiamine deficiency impairs the integrity of the blood-brain barrier, thereby enabling iron to pass through and accumulate in the brain. This hypothesis is based on findings from animal, translational, and neuroimaging studies, discussed in this article. To validate this hypothesis, translational studies focusing on brain iron homeostasis in AUD, as well as prospective clinical studies investigating prevalence and clinical impact of BIO in AUD, should be conducted. If proven right, this would change the understanding of ARD and may lead to novel therapeutic interventions in prevention and treatment of ARD.

Screening for post-traumatic stress disorders in 1017 cancer patients and correlation with anxiety, depression, and distress.

OBJECTIVE: Post-traumatic stress disorder (PTSD) is a severe psychiatric disorder, which might develop after a traumatic event, like cancer diagnosis, and threatens the patient's psychological and/or physiological integrity. Anxiety, depression, and mental distress are known to be common in cancer patients; however, the frequency of PTSD was not investigated thoroughly in this patient group so far. Here, we aim to screen cancer patients for PTSD symptoms and determine a possible correlation with anxiety, depression, and distress. METHODS: The study was performed at the Divisions of Hematology and Oncology of the Medical University of Vienna from 2010 to 2018. Following written consent, patients were asked to fill out the validated self-assessment questionnaire for PTSS-10 and HADS. The study was approved by the institutional ethics committee of the Medical University of Vienna (EC Nr: 2255/2016). RESULTS: A total of 1017 adult cancer patients (513 male, 504 female) were included in a cross-sectional single-center study. Mean age was 57.6 years (SD 14.4 years); 31.7%, 14.6%, 13.2%, and 27.4% of patients outscored the predefined thresholds for self-assessed cases of PTSD, anxiety, depression, and distress, respectively. Compared with men, women showed a higher prevalence of symptoms for PTSD (38.9% vs 24.5%; P < .001) and anxiety (20.4% vs 8.6%; P < .001). The scores of HADS-A, HADS-D, and the combined HADS score (distress) were significantly correlated with PTSS-10 scores (P < .01). No differences in age were observed among the different score groups. CONCLUSION: The study shows a significant prevalence as well as a correlation of PTSD symptoms with anxiety, depression, and distress among cancer patients. Findings underscore the necessity of a serious screening for psychiatric disorders, especially in female patients. In order to enable multidisciplinary care for cancer patients and to reduce the burden for psychiatric disorders, interdisciplinary screening and treatment concepts, which take into account gender aspects, are urged.

Correlation of affective temperament and psychiatric symptoms in palliative care cancer patients.

BACKGROUND: Psychiatric symptoms are common in terminally ill patients. Studies linking temperamental traits and psychiatric disorders in patients suffering from advanced disease are rare. This study investigated the influence of temperament on depression and anxiety in palliative care cancer patients. METHODS: A total of 53 patients at the palliative care unit (PCU) of the Medical University of Vienna were enrolled in the study. Patients filled out the TEMPS-M and the brief PHQ-9 questionnaires to examine associations between temperament, psychiatric symptoms and sociodemographic parameters. RESULTS: Pain (67%), anorexia (58%), constipation (42%) and nausea/vomiting (40%) were the most prevalent self-reported symptoms. Self-reported symptoms of depression were less commonly reported (21.8%) than unveiled by the structured assessment by the PHQ-9 questionnaire: 26.4% (n = 14) showed mild symptoms of depression and 64.1% (n = 34) had a major depressive disorder (MDD) according to PHQ-9. The depressive and cyclothymic temperaments showed significant associations with depressive (both: p < 0.001) as well as symptoms of anxiety (p = 0.002; p = 0.036). Furthermore, the anxious temperament was significantly associated with symptoms of depression (p = 0.027). CONCLUSIONS: Mood disorders are common in palliative care patients, as the majority of the patients were suffering from MDD. The depressive, cyclothymic and anxious temperaments were found to be correlated with depressive and anxious symptoms. A sensitization in this field might bring further improvements for the quality of life of palliative care patients and help to appropriately address psychiatric symptoms in palliative care.

Suicide among 915,303 Austrian cancer patients: who is at risk?

OBJECTIVES: The aim of this study was to determine whether time since first diagnosis, site, and stage of cancer impacted suicide risk within a nationwide cohort of Austrian cancer patients. METHODS: Data for this population-based study were derived from the Austrian National Cancer Registry and Austrian Statistics on Causes of Death. The study of population comprised 915,303 patients diagnosed with cancer between 1983 and 2000 and 14,532,682 person-years of follow-up. Standardized suicide mortality ratios (SMRs) were calculated by sex, time since first diagnosis, site, and stage of cancer. RESULTS: A total of 2877 suicides were registered among all cancer patients over the observation period. Indicating excess suicide risk relative to the general Austrian population, the SMR for the patient cohort was 1.23 (95% CI: 1.19-1.28), and was higher for men (1.41; 95% CI: 1.35-1.47) than women (1.24; 95% CI: 1.15-1.34). This excess risk varied with time since first cancer diagnosis. SMRs peaked in year one after diagnosis (3.17; 95% CI: 2.96-3.40). An excess suicide risk was observed for patients with late locally advanced (SMR=1.59; 95% CI: 1.47-1.71) or metastasized cancer (SMR=4.07; 95% CI: 3.58-4.61), and cancers of the lung (SMR 3.86; 95% CI: 3.36-4.42) and central nervous system (SMR 2.81; 95% CI: 1.92-3.97). LIMITATIONS: No data were available on psychiatric comorbidities, genetic variables, family characteristics, social factors, and community characteristics. CONCLUSIONS: Our study shows that cancer patients have an excess risk for suicide, relative to the general population, which varies with time since first diagnosis, disease severity, and anatomical site. The diagnostic process needs to be sensitive and responsive to their mental health needs. Psychological care should be an integral component of cancer treatment programs.

Relationship between substance use and body mass index in young males.

Recent findings in basic scientific research, such as neurobiological and neuroimaging studies, have suggested common pathways for food and drug intake. It was hypothesized that both compete for the same brain reward sites, and that a higher body mass index (BMI) may be associated with lower substance use. The aim of this study was to investigate the relationship between BMI and substance use in a large sample of young male adults. The sample consisted of 1,902 18-year-old males from a province of Austria in a naturalistic cross-sectional setting. Questionnaires were administered to assess alcohol abuse and dependence (CAGE) and nicotine dependence (Heavy Smoking Index). Urine samples were collected to assess the prevalence of recent illicit drug use. Associations between BMI and substance use were calculated by means of logistic regression analyses. An inverse relationship between BMI and recent illicit drug use was found. This relationship remained significant after adjusting for possible confounding factors such as level of education, nicotine dependence, breath carbon monoxide (CO) levels, and alcohol abuse and dependence. No significant association was found between BMI and nicotine and alcohol dependence. A higher BMI was associated with lower illicit drug use in our sample of young adult males. These results provide further evidence for the hypothesis that food and drugs may compete for the same brain reward sites.

[The chameleon of psychiatry - psychiatric manifestations of neurosyphilis]. / Das Chamäleon der Psychiatrie - Psychiatrische Manifestationsformen der Neurosyphilis.

OBJECTIVE: Recent epidemiological data have shown a significant increase in the prevalence of syphilis. If left untreated, up to 30 % of patients may develop tertiary syphilis, which can manifest as neurosyphilis. The aim of our review is to evaluate psychiatric manifestations of neurosyphilis according to ICD-10. METHODS: A systematic electronic search for published studies (1995-2010) was performed using the databases Medline, Embase, Cochrane as well as the search engines Scopus and Google Scholar. RESULTS: 113 studies were used for detailed analysis. Clinical manifestations of various forms of neurosyphilis are protean, numerous and non-specific and could be on the differential diagnosis for many psychiatric presentations according to ICD-10. CONCLUSION: Due to our results, the difficulties in diagnosing syphilis and current epidemiological data, routine screening tests are still mandatory in the psychiatric field. Further, neurosyphilis still has to be considered in the differential diagnosis within the context of psychiatric conditions and diseases.
