Correlates of major medication side effects interfering with daily performance: results from a cross-sectional cohort study of older psychiatric patients

Anxiolytic-like effects of extremely low frequency electric field in stressed rats: involvement of 5-HT2C receptors

BACKGROUND

Possible modulatory effects of noninvasive brain stimulation have gained interest recently. In our study, the effect of low frequency electric fields (LF-EF) on stress-induced electrophysiological, behavioral changes and the possible involvement of serotonergic 5-HT2C receptors were investigated.

MATERIALS AND METHODS

A total of eight groups including the control groups were formed by applying LF-EF with or without a 5-HT2C receptor agonist to naïve or acute stress exposed rats to demonstrate the effects of LF-EF. LF-EF administration at 10 kV/m was started 30 min before acute stress application and lasted for 1 h in total. Anxiety levels and social interaction were evaluated using the elevated plus maze test and social interaction test, respectively. Auditory evoked potentials (AEP) were recorded by using ascending loudness paradigms. Loudness dependence AEP (LDAEP) was calculated by using amplitude values to analyze serotonergic transmission. Serotonin and glucocorticoid levels were measured in the frontal cortex and hippocampus.

RESULTS

It was observed that the applied LF-EF reduced the anxiety behavior, and attenuated the LDAEP responses in stress and/or 5-HT2C receptor agonist applied groups. In parallel, an increase in serotonin levels and a decrease in glucocorticoid levels were observed. However, LF-EF exposure was ineffective in impaired social interaction.

CONCLUSIONS

Our findings show that 10 kV/m LF-EF administration may modulate the neural network and physiological responses associated with mild acute stress. 5-HT2C receptor dependent functions are thought to play a role in the anxiolytic effect of LF-EF.

Why we need to evaluate long-term antidepressant use in older patients with depression

In this commentary, we address current clinical practice of long-term antidepressant use in older adults with depression, and recommend improvements. Compared with younger adults, older adults more frequently use antidepressants in the long term, although they may not always benefit from them, and in spite of an increased risk for adverse events. Unfortunately, evaluations of long-term antidepressant use are sparse, especially in older age groups. To prevent and reduce inappropriate long-term use and adverse events, antidepressant use in older age groups should be regularly evaluated.

Less Is More: The Impact of Deprescribing Psychotropic Drugs on Behavioral and Psychological Symptoms and Daily Functioning in Nursing Home Patients. Results From the Cluster-Randomized Controlled COSMOS Trial

OBJECTIVE

To investigate the impact of medication reviews using collegial mentoring and systematic clinical evaluation on psychotropic prescriptions, behavioral and psychological symptoms of dementia (BPSD), and activities of daily living (ADL).

DESIGN

Four-month multicenter, multicomponent, cluster-randomized, single-blinded controlled trial.

SETTING

Thirty-three Norwegian nursing homes including 67 nursing home wards (clusters).

PARTICIPANTS

A total of 723 enrolled patients, of which 428 participated in the study; 217 were randomized to the intervention and 211 to care as usual (control).

INTERVENTION

The COSMOS intervention consisted of Communication, Systematic pain management, Medication reviews, Organization of activities, and Safety. During medication review, the nursing home physician evaluated treatment with colleagues systematically using the results from validated clinical assessments.

MEASUREMENTS

Mean changes from baseline to month 4 in the number of prescribed psychotropic drugs (antipsychotics, anxiolytics, hypnotics or sedatives, antidepressants, and antidementia drugs); Neuropsychiatric Inventory Nursing Home Version (NPI-NH) and Cornell Scale of Depression in Dementia (CSDD); Lawton and Brody's Physical Self Maintenance Scale (PSMS).

RESULTS

Compared to control, the mean change in prescribed psychotropic drugs was reduced both in total and regular number, while mean changes in NPI-NH and CSDD scores did not differ between the groups. Mean change in PSMS showed improvement in the intervention group, and deterioration in the control group.

CONCLUSION

Medication reviews using collegial mentoring and systematic clinical evaluation led to safe deprescribing, as the reductions in psychotropic drug use did not negatively affect BPSD, while ADL improved.

Potential drug-drug interactions and polypharmacy in institutionalized elderly patients in a public hospital in Brazil

WHAT IS KNOWN ON THE SUBJECT?: Older individuals constitute an increasing proportion of the population, and therefore, are the major consumers of drugs. The elderly, especially those with mental disabilities, frequently develop chronic diseases and start using numerous drugs. Drug-drug interactions (DDIs) are a major clinical problem in the elderly population, and previous studies have focused only on antidepressants and others types of drugs used to treat mental health conditions. WHAT THIS ARTICLE ADDS TO EXISTING KNOWLEDGE?: This study shows that in hospitalized elderly patients with mental disorders (aged 60-69 years), polypharmacy (≥5 drugs) and the use of drugs that act on the cardiovascular, respiratory and nervous systems can lead to potential drug-drug interactions. Moreover, it was reported that the prevalence of drug-drug interactions in elderly patients with mental disorders was high during their hospitalization in a public hospital in Brazil. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Nurses should know the factors associated with drug-drug interactions in hospitalized elderly patients with mental disorders to choose appropriate strategies for avoiding treatment failure and adverse events in patients.

ABSTRACT

Introduction Despite the impact on patient safety and the fact that prevalence is higher in older patients, previous research did not analyse drug-drug interactions (DDIs) in view of nursing care of elderly psychiatric patients. Aim To identify potential drug-drug interactions and polypharmacy in prescriptions of aged inpatients with psychiatric disorders and analyse associated factors. Methods In this retrospective cross-sectional study, we analysed the medical records of institutionalized patients diagnosed with psychiatric disorders (n = 94), aged >60 years, and prescribed multiple medications. Drug prescriptions were checked at admission, midway through and the last prescription. Factors associated with DDI occurrence were assessed using multivariable logistic regression analysis. Results A DDI prevalence potential of 67.0%, 74.5% and 80.8% occurred in patients at admission, midway through hospitalization and the last prescription, respectively. Most of the prescribed drugs were nervous system agents. A high percentage of serious and contraindicated potential DDIs occurred. Age between 60 and 69 years, use of cardiovascular and respiratory system drugs, and the number of medications contributed significantly to DDI. Implications for mental health nursing Knowledge on the factors associated with DDIs in patients with mental disorders can contribute to the improvement of effectiveness and safety of nursing care.

Hospital admission in older persons presenting with dizziness in the Emergency department

One of the most frequent chief complaints among older persons presenting in the emergency department (ED) is dizziness. Nurses in the ambulance and in the ED play an important role in managing these patients. The challenge in the ED or ambulance is to, with limited diagnostic equipment; decide the correct level of care. The aim of this study was to identify factors that differed between those who were admitted to hospital and those who were not among older persons (65+) presenting in the ED with dizziness. The method was a retrospective journal audit. The sample consisted of persons (n=166) aged 65+ presenting in the ED with dizziness. Factors that were more frequent among those admitted to hospital were arriving with ambulance, priority and number of medications and high age. Forty percent of the dizzy patients were admitted to the hospital, 50% among those arriving with ambulance and 24% of the walk-in patients. Among the 166 patients included in the study because of dizziness, 64 different discharge diagnoses emerged, illustrating the complex nature of dizziness as a symptom. The results from this study can help the ambulance or ED nurse doing the first assessment with limited information and initiating the management, knowing what factors that are more frequent in older persons being admitted when presenting with dizziness.
