Pharmacovigilance in Gerontopsychiatric Patients

The purpose of this multicenter-study is to investigate safety of psychopharmacological treatment and rates of adverse drug reactions in gerontopsychiatric inpatients. Elderly people are at higher risk for developing side effects under pharmacological treatment due to an altered metabolic situation, higher comorbidity rates and often polypharmacy. Furthermore gerontopsychiatric patients can often not articulate their symptoms clearly, for example due to pronounced cognitive impairment.
The aim of the study is to gain valid data of possible adverse drug reaction rates, their potential risk factors and outcome, as well as medical prescription practises.
To assess these outcomes an intensive pharmacovigilance-monitoring will be conducted at the five participating study sites.
At Baseline demographic data, previous and present disorders, use of drugs, previous and present medication, quality of life, cognitive function, physical examination results, laboratory results and ECG will be assessed.
Afterwards patients are visited weekly and screened for possible adverse drug reactions. All adverse drug reactions will be coded in the MedDRA-system.
In case of a possible serious adverse drug reaction serum levels of all psychotropic substances applicated will be assessed. Drug combinations will be analysed using an established advanced bioinformatic tool (mediQ). Diagnosis, medication intake and possible adverse drug reactions are documented continually.
2 weeks after discharge from the ward, patients will be contacted by phone to assess catamnestic data.

Effects of Discontinuation of Benzodiazepine-derivative Hypnotics on Cognitive and Motor Functions in Elderly Persons: a Pilot Study

Benzodiazepines (BZDs) have been reported to cause negative impacts on motor as well as cognitive functions, which in turn could result in lethal incidents including falls especially in the elderly. This notwithstanding, few trials have evaluated a feasibility and benefits of discontinuing BZD-derivative hypnotics in a systematic manner in this frail population. In this 8-week open-label study, we examined changes in motor and cognitive functions following the discontinuation of BZD hypnotics in older persons.
OBJECTIVES & HYPOTHESES
Primary Objective The primary objective is to examine the feasibility of discontinuing BZD-derivative hypnotics in older people.
Secondary Objectives
One of the secondary objectives is to examine the magnitude of discontinuing BZD-derivative hypnotics in the stability of body.
Another secondary objective is to examine the magnitude of discontinuing BZD-derivative hypnotics in cognitive function.
Hypotheses
1. More than 80% of the participants will complete and tolerate all the study procedures.
2a. Participants will show an improvement in the stability of body. 2b. Participants will show an improvement in the cognitive function globally as well as specifically in attention.

Repeated lyophilization: A neo-method for urine-based reference materials preparation

Article

作者: Liu, Yu ; Zhi, Yujie ; Zhang, Zhen ; Jin, Wenhui ; Hu, Jing ; Liu, Wei ; Zheng, Qiongying ; Zhang, Wenping ; Lu, Jiayue ; Dou, Quanlu ; Chen, Hang

In urine drug testing, a cut-off value is often imposed to determine whether the sample is negative or positive. A matrix containing a reference substance helps counteract the adverse effects of the urine matrix across different laboratories to improve the consistency of final results. However, as a biological matrix, urine is prone to corruption and other problems that make it difficult to use as a reference sample. In this study, morphine, nitrazepam, lorazepam, buprenorphine, zolpidem, midazolam, diazepam, and clozapine commonly used in clinical practice were selected as target analytes, and the preparation process was further optimized to repeated lyophilization, in order to obtain more effective, stable, and accurate urine matrix reference materials (mRMs). The appropriate urine density (1.010-1.017 kg/m³) for preparing lyophilized samples was investigated through density determination. Conducting repeated lyophilizations resulted in a denser powder with reduced susceptibility to collapse and improved the quality of lyophilized urine samples. Lyophilized urine mRMs could be stored at room temperature for one month or under refrigeration conditions (4 ℃) for six months.

TRPV1‐dependent NKCC1 activation in mouse lens involves integrin and the tubulin cytoskeleton

Article

作者: Delamere, Nicholas A. ; Shahidullah, Mohammad ; Mandal, Amritlal

Abstract:

Previously we showed hyperosmotic solution caused TRPV1‐dependent NKCC1 activation in the lens by a mechanism that involved ERK1/2 signaling. In various tissues, integrins and the cytoskeletal network play a role in responses to osmotic stress. Here, we examined the association between integrins and TRPV1‐dependent activation of NKCC1 in mouse lens epithelium. Wild‐type (WT) lenses exposed to the integrin agonist leukadherin‐1 (LA‐1) for 10 min displayed a ~33% increase in the bumetanide‐sensitive rate of Rb uptake indicating NKCC activation. Paclitaxel, a microtubule stabilizing agent, abolished the Rb uptake response. In primary cultured lens epithelium LA‐1 caused a robust ERK1/2 activation response that was almost fully suppressed by paclitaxel. The TRPV1 agonist capsaicin caused a similar ERK1/2 activation response. Consistent with an association between integrins and TRPV1, the TRPV1 antagonist A889425 prevented the Rb uptake response to LA‐1 as did the ERK inhibitor U0126. LA‐1 did not increase Rb uptake by lenses from TRPV1 knockout mice. In cells exposed to a hyperosmotic stimulus, both the ERK1/2 activation and Rb uptake responses were prevented by paclitaxel. Taken together, the findings suggest TRPV1 activation is associated with integrins and the tubulin cytoskeleton. This aligned with the observation that LA‐1 elicited a robust cytoplasmic calcium rise in cells from WT lenses but failed to increase calcium in cells from TRPV1 knockout lenses. The results are consistent with the notion that integrin activation by LA‐1, or a hyperosmotic stimulus, causes TRPV1 channel opening and the consequent downstream activation of the ERK1/2 and NKCC1 responses.

Enhanced Anticancer Activity of 7MeERT over Ertredin: A Comparative Study on Cancer Cell Proliferation and NDUFA12 Binding.

Article

We have previously identified Ertredin (3-(2-amino-5-bromophenyl) quinoxalin-2(1H)-one) as a compound that suppresses 3D spheroid formation and tumorigenesis in NIH3T3 cells induced by Epidermal Growth Factor Receptor variant III (EGFRvIII) transduction. One of its targets has been shown to be NDUFA12 (NADH Dehydrogenase (Ubiquinone) 1 Alpha Subcomplex Subunit 12), a component protein of oxidative phosphorylation complex I. In this report, we compared the growth inhibitory activity of Ertredin with its methylated analogue 7MeERT (3-(2-amino-5-bromophenyl)-7-methylquinoxalin-2(1H)-one) on human cancer cells. 7MeERT induced the inhibition of the proliferation of various cancer cells similarly to Ertredin and showed higher activity in glioblastoma cells, A431 cells overexpressing EGFR (wild type), and multiple myeloma cells. Molecular docking analysis and a Cellular Thermal Shift Assay (CETSA) suggested that 7MeERT binds to NDUFA12 similarly to Ertredin. The binding of 7MeERT and Ertredin to NDUFA12 in glioblastoma was further supported by the inhibition of the oxygen consumption rate. These results suggest that 7MeERT also binds to NDUFA12, inhibits oxidative phosphorylation, and has a higher anti-cancer cell growth inhibitory activity than Ertredin.
