The relationship between dietary vitamin k and depressive symptoms in late adulthood: A cross-sectional analysis from a large cohort study
2019
Few studies assessed the associations between dietary vitamin K and depressive symptoms. We aimed to investigate the association between dietary vitamin K and depressive symptoms in a large cohort of North American People. In this cross-sectional analysis, 4,375 participants that were aged 45&ndash
Impact of comorbidities on pharmacotherapy of painful diabetic neuropathy in clinical practice.
2014
Abstract Aims We evaluated the impact of baseline comorbidities on the effectiveness of duloxetine and anticonvulsants (pregabalin/gabapentin) in patients with painful diabetic neuropathy in clinical care. Methods Outcomes from a 6-month, observational study with 2575 patients initiating/switching DPNP treatment were analyzed post-hoc. Propensity scoring was used to adjust for baseline factors influencing treatment choice in 1523 patients receiving duloxetine or anticonvulsants. Analysis of covariance models with fixed effects for baseline pain, treatment, propensity score, baseline characteristics or comorbidities, and their interaction with treatment were used to estimate LSmean effects o…
Effectiveness of a transdiagnostic internet-based protocol for the treatment of emotional disorders versus treatment as usual in specialized care: st…
2015
Emotional disorders (depression and anxiety disorders) are highly prevalent mental health problems. Although evidence showing the effectiveness of disorder-specific treatments exists, high comorbidity rates among emotional disorders limit the utility of these protocols. This has led some researchers to focus their interest on transdiagnostic interventions, a treatment perspective that might be more widely effective across these disorders. Also, the current way of delivering treatments makes it difficult provide assistance to all of the population in need. The use of the Internet in the delivery of evidence-based treatments may help to disseminate treatments among the population. In this stu…
Liver intracellular L-cysteine concentration is maintained after inhibition of the trans-sulfuration pathway by propargylglycine in rats.
1997
To study the fate ofl-cysteine and amino acid homeostasis in liver after the inhibition of the trans-sulfuration pathway, rats were treated with propargylglycine (PPG). At 4 h after the administration of PPG, liver cystathionase (EC4.4.1.1) activity was undetectable,l-cystathionine levels were significantly higher,l-cysteine was unchanged and GSH concentration was significantly lower than values found in livers from control rats injected intraperitoneally with 0.15 M-NaCl. The hepatic levels of amino acids that are intermediates of the urea cycle,l-ornithine,l-citrulline andl-arginine and blood urea were significantly greater. Urea excretion was also higher in PPG-treated rats when compared…
Are ratings of psychomotor retardation correlated with neuropsychological measurements?
1989
The present study investigated the correlation between retardation, assessed by the Bech-Rafaelsen Melancholia Scale (BRMS), and measurements of reaction time and motor performance in 26 elderly depressed patients. Significant correlations were only detected between motor retardation and the number and duration of faults in the line following part of the motor performance test. The total scores of the BRMS and the Hamilton Depression Scale did not correlate significantly with any of the performed measurements.
Psychological insulin resistance in geriatric patients with diabetes mellitus.
2013
To determine the extent to which geriatric patients with diabetes mellitus experience psychological insulin resistance (PIR).A total of 67 unselected geriatric patients with diabetes (mean age 82.8±6.7 years, diabetes duration 12.2 [0.04-47.2] years, 70.1% female) were recruited in a geriatric care center of a university hospital. A comprehensive geriatric assessment (CGA) was performed including WHO-5, Hospital Anxiety and Depression Scale (HADS), Mini Mental State Examination (MMSE) and Barthel-Index. We assessed PIR using the Barriers of Insulin Treatment Questionnaire (BIT) and the Insulin Treatment Appraisal Scale in a face-to-face interview.Insulin-naïve patients (INP) showed higher P…
Longitudinal relationship between B-type natriuretic peptide and anxiety in coronary heart disease patients with depression.
2018
Patients with coronary heart disease (CHD) suffer from physical limitations, but also from psychological distress. Natriuretic peptides may be involved in the neurobiological processes that modulate psychological adaptation, as they are increased in heart disease and seem to have an anxiolytic-like function. Longitudinal data on this association are scarce.To assess the relationship between NT-proBNP and anxiety (Hospital Anxiety and Depression Scale (HADS)), we used secondary data from a multicenter trial from baseline to 24 months. Patients (N = 308, 80.8% male, mean age 60.1 years) had stable CHD and moderate levels of depression (HADS ≥8).Multiple linear regression adjusted for age, sex…
How are neuroticism and depression related to the psychophysiological stress response to acute stress in healthy older people?
2015
Neuroticism and depressive symptomatology have been related to a heightened and diminished physiological stress response, which may partly explain their negative relationship with health and wellbeing. Identifying factors that may increase disease vulnerability is especially relevant in older people, whose physiological systems decline. With this in mind, we investigated the influence of neuroticism and depression on the psychophysiological stress response in healthy older people (from 55 to 76years old). A total of 36 volunteers were exposed to a stressful task (Trier Social Stress Test, TSST), while 35 volunteers performed a control non-stressful task. The physiological stress response wa…
Lasting downregulation of the lipid peroxidation enzymes in the prefrontal cortex of mice susceptible to stress-induced anhedonia
2015
International audience; Antioxidant enzymes and lipid peroxidation in the brain are involved in neuropsychiatric pathologies, including depression. 14- or 28-day chronic stress model induced a depressive syndrome defined by lowered reward sensitivity in C57BL/6J mice and changed gene expression of peroxidation enzymes as shown in microarray assays. We studied how susceptibility or resilience to anhedonia is related to lipid peroxidation in the prefrontal cortex (PFC). With 14-day stress, a comparison of the activities of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPX) and accumulation of malondialdehyde (MDA) revealed a decrease of the first two measures in suscepti…
Nitric oxide-sensitive guanylyl cyclase inhibits acetylcholine release and excitatory motor transmission in the guinea-pig ileum
1997
Abstract This study examined the mechanism through which nitric oxide inhibits the release of acetylcholine and excitatory motor neurotransmission in the guinea-pig ileum. The selective inhibitor of nitric oxide-sensitive guanylyl cyclase, 1 H -[1,2,4]oxadiazolo[4,3- a ]quinoxalin-1-one (ODQ), concentration-dependently enhanced both basal release (−log EC 50 : 6.8) and electrically (10 Hz) -evoked release (−log EC 50 : 6.0) of [ 3 H]acetylcholine from longitudinal muscle-myenteric plexus preparations preincubated with [ 3 H]choline. The increase by ODQ of basal release appeared to be exocytotic since it was prevented by tetrodotoxin (300 nM) and absence of calcium from the superfusion mediu…
