An investigation of neuropsychiatric symptoms, contextual factors, and antidepressant treatment as risk factors for dementia development in people with mild cognitive impairment.

BACKGROUND: While some people with mild cognitive impairment (MCI) progress to dementia, many others show no progression. The aim of this study was to identify factors associated with risk of dementia development in this population. METHOD: A large naturalistic retrospective cohort study was assembled from mental healthcare records in a south London catchment. Patients were selected at first recorded diagnosis of MCI and subsequent dementia diagnosis was ascertained from case notes or death certificate, excluding those with dementia diagnoses and deaths within 6 months of MCI diagnosis. A range of demographic and clinical characteristics were ascertained around MCI diagnosis and Cox proportional hazards models were used to investigate independent predictors of dementia, focussing on neuropsychiatric symptoms, contextual factors, and antidepressant treatment. RESULTS: Of 2250 patients with MCI, 236 (10.5%) developed dementia at least 6 months after MCI diagnosis. Aside from older age, lower cognitive function, and activities of daily living impairment, impaired social relationships and recorded loneliness were associated with a higher risk of developing dementia. Patients of Black (compared to White) ethnicity were at a lower risk. For depression and antidepressant receipt, only tricyclic use compared to no antidepressant use was associated with an increased dementia risk. CONCLUSIONS: No evidence was found for co-morbid affective disorders or different antidepressant classes as risk factors for dementia development following MCI diagnosis, but loneliness and social impairment were independent predictors and would be worth evaluating as targets for interventions to delay progression.

The impact of the first UK COVID-19 lockdown on presentations with psychosis to mental health services for older adults: An electronic health records study in South London.

OBJECTIVES: Social distancing restrictions in the COVID-19 pandemic may have had adverse effects on older adults' mental health. Whereby the impact on mood is well-described, less is known about psychotic symptoms. The aim of this study was to compare characteristics associated with psychotic symptoms during the first UK lockdown and a pre-pandemic comparison period. METHODS: In this retrospective observational study we analysed anonymised records from patients referred to mental health services for older adults in South London in the 16-week period of the UK lockdown starting in March 2020, and in the comparable pre-pandemic period in 2019. We used logistic regression models to compare the associations of different patient characteristics with increased odds of presenting with any psychotic symptom (defined as hallucinations and/or delusion), hallucinations, or delusions, during lockdown and the corresponding pre-pandemic period. RESULTS: 1991 referrals were identified. There were fewer referrals during lockdown but a higher proportion of presentations with any psychotic symptom (48.7% vs. 42.8%, p = 0.018), particularly hallucinations (41.0% vs. 27.8%, p < 0.001). Patients of non-White ethnicity (adjusted odds ratio (OR): 1.83; 95% confidence interval (CI): 1.13-2.99) and patients with dementia (adjusted OR: 3.09; 95% CI: 1.91-4.99) were more likely to be referred with psychotic symptoms during lockdown. While a weaker association between dementia and psychotic symptoms was found in the pre-COVID period (adjusted OR: 1.55; 95% CI: 1.19-2.03), interaction terms indicated higher odds of patients of non-White ethnicity or dementia to present with psychosis during the lockdown period. CONCLUSIONS: During lockdown, referrals to mental health services for adults decreased, but contained a higher proportion with psychotic symptoms. The stronger association with psychotic symptoms in non-White ethnic groups and patients with dementia during lockdown suggests that barriers in accessing care might have increased during the COVID-19 pandemic.

An evaluation of two behavioral rehabilitation programs, qigong versus progressive relaxation, in improving the quality of life in cardiac patients.

OBJECTIVES: The aim of the current study was to evaluate and compare two different behavioral rehabilitation programs in improving the quality of life in cardiac patients in Hong Kong. DESIGN AND SETTING: The current study was carried out in the outpatient unit of Occupational Therapy Department in the United Christian Hospital, Hong Kong. Convenience sampling with referral from the cardiac specialty was used in the present study. SUBJECTS: A total of 65 subjects, with a mean age 65 (range, 42 to 76), were recruited in the study. The cardiac diseases included myocardial infarct, postcoronary intervention, valve replacement, and also ischemic heart disease. INTERVENTIONS: Patients were alternately allocated to the two groups. The first group of patients received instructions and practiced on progressive relaxation. The second group of patients underwent training in qigong. A total of eight sessions were conducted and each session lasted 20 minutes. OUTCOME MEASURES: Demographic and clinical data such as gender, age, and systolic and diastolic blood pressure were recorded. The psychological and Quality of Life assessment was performed using the Chinese versions of Short Form 36 (C-SF36), State-Trait Anxiety Inventory (C-STAI), and General Health Questionnaire (C-GHQ-12). RESULTS: Fifty-nine (59) subjects (44 men and 15 women) completed all eight rehabilitation sessions in the study. Patients allocated to the two treatment groups had comparable baseline characteristics. Progressive relaxation was more effective in reducing blood pressures compared to qigong. Relaxation appeared to be particularly beneficial in somatic domains. qigong group demonstrated greater improvement in psychologic measures in addition to reduction in systolic blood pressure. CONCLUSIONS: Progressive relaxation and qigong exercise improved the quality of life for cardiac patients with reference to certain physiologic and psychologic measures. The result was supported by previous studies and literature reviews on qigong in terms of its effect on the psychologic dimension.

Relaxation training methods for nurse managers in Hong Kong: a controlled study.

Nurse managers are under increased stress because of excessive workloads and hospitals' restructuring which is affecting their work tasks. High levels of stress could affect their mental health. Yet, few stress management training programmes are provided for this population. The purpose of this study was to apply stretch-release relaxation and cognitive relaxation training to enhance the mental health for nurse managers. A total of 65 nurse managers in Hong Kong were randomly assigned to stretch-release relaxation (n = 17), cognitive relaxation (n = 18), and a test control group (n = 35). Mental health status was assessed using the Chinese version of State-Trait Anxiety Inventory and the Chinese version of the General Health Questionnaire. Participants were assessed at the pretreatment session, the fourth posttreatment session, and at the 1-month follow-up session. The results revealed both the stretch-release and cognitive relaxation training enhanced mental health in nurse managers in Hong Kong. The application of relaxation training in enhancing mental health status for nurses and health professionals is discussed.

Qigong: harmonising the breath, the body and the mind.

Qigong is a form of exercise developed in China over millennia to prevent illness and foster physical and mental health. Despite many claims of the therapeutic effects of Qigong, the fundamental concepts and principles underlying this holistic therapy remain unfamiliar to Western populations. This article helps practitioners to understand the art of Qigong based on three main principles, harmonising the breath, the body and the mind.

A controlled trial of music and pre-operative anxiety in Chinese men undergoing transurethral resection of the prostate.

AIM OF THE STUDY: To test the effects of music intervention on pre-operative anxiety in Chinese males undergoing transurethral resection of the prostate. RATIONALE: No studies have measured the effects of music intervention in reducing pre-operative anxiety for patients with transurethral resection of the prostate (TURP). Previous studies have examined the effects of music on pre-operative anxiety but have not examined the possible effects of the presence of a carer as an independent variable in pre-operative anxiety levels of patients in addition to the music intervention. The cultural validity of applying a music intervention to the reduction of pre-operative anxiety was also investigated. DESIGN: A quasi-experimental design with three groups: music intervention, nurse presence and control group. METHOD: Thirty patients having TURP were randomly assigned (n = 10 each group) to one of the three groups. Pre- and post-test measures of systolic and diastolic blood pressure, heart rate and state anxiety using the Chinese State-Trait Anxiety Inventory (C-STAI) were obtained for the three groups. RESULTS: The findings showed that the music intervention significantly reduced all blood pressure levels for the patients. A reduction in state anxiety level was also found for the music intervention group. No significant reductions in blood pressure, heart rate and state anxiety level were found in the nurse presence and control groups. CONCLUSION: The results support the cross-cultural validity of using a music intervention in pre-operative anxiety reduction, in this case for TURP patients waiting in the theatre holding area.
