Moderating effect of emotional support on the relationship between disability and life satisfaction in older adults

Haron SA, Foong HF, Hamid TA

Geriatr Gerontol Int, 2018 Sep;18(9):1361-1365.
PMID: 30044041 DOI: 10.1111/ggi.13490

AIM: Disability is strongly linked to poorer life satisfaction among older persons. Such close correlations warrant better understanding of the underlying moderator in which negative effects of the former on the latter can be reduced. More specifically, it is the aim of this study to examine the moderating effect of emotional support on the relationship between disability and life satisfaction.
METHODS: The study included 2322 nationally represented community-dwelling older persons in Malaysia who participated in the baseline study of Neuroprotective Model for Healthy Longevity. In order to test the moderating effect of emotional support on the association between disability and life satisfaction, a series of hierarchical multiple linear regression models were utilized, after controlling for potential covariates associated with life satisfaction.
RESULTS: Bivariate analyses showed that disability negatively predicted life satisfaction, whereas emotional support positively predicted life satisfaction. Furthermore, the moderated hierarchical regression analysis showed that emotional support moderated the association between disability and life satisfaction, after controlling for potential covariates, such that the negative relationship between disability and life satisfaction was stronger for individuals with lower levels of emotional support.
CONCLUSIONS: The presence of emotional support might reduce the negative effects of disability on life satisfaction. These findings have important clinical implications, especially in developing better strategies to help disabled older persons to cope with their disabilities; with the hope that in the long term, a society with healthy longevity can be established.

PMID: 32985044 DOI: 10.1111/psyg.12614

BACKGROUND: Little is known about gender differences in the relationship between religious orientation and life satisfaction in older adults living with chronic disease(s). Therefore, the purpose of this article was to examine the moderating effect of gender on the association between religious orientation and life satisfaction in older adults living with morbidity and multimorbidity.
METHODS: The study involved 1790 community-dwelling older adults aged 60 and above living with at least one chronic medical condition. The Satisfaction with Life Scale and Revised Intrinsic/Extrinsic Religious Orientation Scale were used to measure life satisfaction and religious orientation. Moderated hierarchical multiple regression was used to test the moderation effect.
RESULTS: Results showed that while intrinsic religiosity was positively associated with life satisfaction, extrinsic religiosity was found to have a negative relationship with life satisfaction. Gender moderated the association between intrinsic religiosity and life satisfaction.
CONCLUSIONS: The findings suggested that the positive impact of intrinsic religiosity on life satisfaction was stronger in older women living with morbidity and multimorbidity. Healthcare practitioners can help disadvantaged older women in identifying their religious values and practices to improve their subjective wellbeing.
Information processing speed as a mediator between psychosocial stress and global cognition in older adults

Psychogeriatrics, 2018 Jan;18(1):21-29.
PMID: 29372603 DOI: 10.1111/psyg.12279

BACKGROUND: The link between psychosocial stress and cognitive function is complex, and previous studies have indicated that it may be mediated by processing speed. Therefore, the main aim of this study was to examine whether processing speed mediates the association between psychosocial stress and global cognition in older adults. Moreover, the moderating role of gender in this model is examined as well.
METHODS: The study included 2322 community-dwelling older adults in Malaysia who were randomly selected through a multistage proportional cluster random sampling technique. Global cognition construct was measured by the Mini-Mental State Examination and Montreal Cognitive Assessment; psychosocial stress construct was measured by perceived stress, depression, loneliness, and neuroticism; and processing speed was assessed by the Digit Symbol Substitution Test. Structural equation modelling was used to analyze the mediation and moderation tests.
RESULTS: Processing speed was found to partially mediate the relationship between psychosocial stress and global cognition (β in the direct model = -0.15, P

Thyrotoxicosis is associated with cardiac dysfunction; more commonly, left ventricular dysfunction. However, in recent years, there have been more cases reported on right ventricular dysfunction, often associated with pulmonary hypertension in patients with thyrotoxicosis. Three cases of thyrotoxicosis associated with right ventricular dysfunction were presented. A total of 25 other cases of thyrotoxicosis associated with right ventricular dysfunction published from 1994 to 2017 were reviewed along with the present 3 cases. The mean age was 45 years. Most (82%) of the cases were newly diagnosed thyrotoxicosis. There was a preponderance of female gender (71%) and Graves' disease (86%) as the underlying aetiology. Common presenting features included dyspnoea, fatigue and ankle oedema. Atrial fibrillation was reported in 50% of the cases. The echocardiography for almost all cases revealed dilated right atrial and or ventricular chambers with elevated pulmonary artery pressure. The abnormal echocardiographic parameters were resolved in most cases after rendering the patients euthyroid. Right ventricular dysfunction and pulmonary hypertension are not well-recognized complications of thyrotoxicosis. They are life-threatening conditions that can be reversed with early recognition and treatment of thyrotoxicosis. Signs and symptoms of right ventricular dysfunction should be sought in all patients with newly diagnosed thyrotoxicosis, and prompt restoration of euthyroidism is warranted in affected patients before the development of overt right heart failure.
Learning points: Thyrotoxicosis is associated with right ventricular dysfunction and pulmonary hypertension apart from left ventricular dysfunction described in typical thyrotoxic cardiomyopathy.Symptoms and signs of right ventricular dysfunction and pulmonary hypertension should be sought in all patients with newly diagnosed thyrotoxicosis.Thyrotoxicosis should be considered in all cases of right ventricular dysfunction or pulmonary hypertension not readily explained by other causes.Prompt restoration of euthyroidism is warranted in patients with thyrotoxicosis complicated by right ventricular dysfunction with or without pulmonary hypertension to allow timely resolution of the abnormal cardiac parameters before development of overt right heart failure.
Late clinical and magnetic resonance imaging follow up of Nipah virus infection

The Nipah virus is a newly identified paramyxovirus responsible for an outbreak of fatal encephalitis in Malaysia and Singapore. This paper reports the follow up clinical and magnetic resonance imaging findings in 22 affected subjects. Of 13 patients with encephalitis, one died, one was lost to follow up, and seven recovered. Among the four remaining patients, one had residual sixth nerve palsy, another suffered from severe clinical depression, and a third patient had evidence of retinal artery occlusion. One patient with delayed onset Horner syndrome had a single lesion in the cervical spinal cord. The brain magnetic resonance findings were stable or improved in nine patients over 18 months of follow up. Among a second group of nine asymptomatic seropositive abattoir workers, magnetic resonance examination in seven subjects revealed discrete small lesions in the brain; similar to those detected in encephalitis patients. These findings suggest that in addition to encephalitis, the newly discovered Nipah virus affects the spinal cord and the retina. Late clinical and radiological findings can occur in Nipah virus infections as with other paramyxoviruses.

BACKGROUND AND PURPOSE: An epidemic of suspected Japanese encephalitis occurred in Malaysia in 1998-1999 among pig farmers. In neighboring Singapore, an outbreak occurred among pig slaughterhouse workers. It was subsequently established that the causative agent in the outbreak was not the Japanese encephalitis virus but a previously unknown Hendra-like paramyxovirus named Nipah virus.
METHODS: The brain MR images of eight patients with Nipah virus infection were reviewed. All patients tested negative for acute Japanese encephalitis virus. Seven patients had contrast-enhanced studies and six had diffusion-weighted examinations.
RESULTS: All patients had multiple small bilateral foci of T2 prolongation within the subcortical and deep white matter. The periventricular region and corpus callosum were also involved. In addition to white matter disease, five patients had cortical lesions, three had brain stem involvement, and a single thalamic lesion was detected in one patient. All lesions were less than 1 cm in maximum diameter. In five patients, diffusion-weighted images showed increased signal. Four patients had leptomeningeal enhancement and four had enhancement of parenchymal lesions.
CONCLUSION: The brain MR findings in patients infected with the newly discovered Nipah paramyxovirus are different from those of patients with Japanese encephalitis. In a zoonotic epidemic, this striking difference in the appearance and distribution of lesions is useful in differentiating these diseases. Diffusion-weighted imaging was advantageous in increasing lesion conspicuity.
