Effect of a multi-domain intervention on the quality of life in older adults with major neurocognitive disorder: A pilot study.

PURPOSE: Major neurocognitive disorders (MND) have multiple negative consequences on patients' lives and on their caregivers' health. Occupational therapy and cognitive stimulation have failed to show any significant efficacy on quality of life (QoL), cognitive functioning and behavioural symptoms. Bretonneau Hospital's Day Care Unit offers personalized and structured multi-domain interventions to cognitively impaired older patients on a weekly basis, for a 3-month period. OBJECTIVES: Our objective was to determine whether a specific rehabilitation day care unit (RDCU) could influence the QoL of cognitively impaired community-dwelling elderly patients. We also aimed to better understand the characteristics of patients who had the most benefited from the RDCU. METHODS: Retrospective study based on a sample of outpatients participating in RDCU during three months. All patients underwent a cognitive (MMS), functional (IADl, ADL) and behavioral (NPI) assessment. We compared QoL using the QoL-Alzheimer's Disease (QoL-AD) scale before and after RDCU. RESULTS: Overall, we included 60 outpatients in our study (mean age 83.3±5.8; women=70%). We found a statistically significant improvement of QoL-AD scores after RDCU (31.8±4.9 to 32.9±5.2, P=0.008). Patients who benefitted the most from RDCU were older (P=0.01) and had lower baseline QoL (P=0.04). We did not find any other characteristics associated with QoL-AD score improvement in our population. CONCLUSION: RDCU showed positive effects on QoL in this uncontrolled pilot study of older adults with MND. These findings should be confirmed in a future randomized controlled trial to corroborate the potential benefits of RDCU on QoL in older cognitively impaired patients.

African dust clouds are associated with increased paediatric asthma accident and emergency admissions on the Caribbean island of Trinidad

Objective: To determine if there is any association between paediatric Accident & Emergency (A&E) asthma admissions and Saharan dust cloud cover Methods: A retrospective ecological study of paediatric asthma patients who attended the A&E department of the Eric Williams Medical Sciences Complex in relation to Saharan dust visibility andother climactic variables for the period May 23 2001 to May 13 2002. A quasi-likelihood approach was used to develop a statistical model for the relationship between acute paediatric asthma A&Evisits and Saharan dust cover.Results: 2655 A&E visits for acute asthma during the study period. There were significant associations between paediatric admissions and two climate variables; Saharan dust levels (p <0.05)and barometric pressure (p <0.01). In the absence of dust however, barometric pressure by itself hadno predictive power. Dust cover & barometric pressure were most strongly associated with increased admissions the day after dust cover Conclusions: Saharan dust cloud cover over Trinidad was associated with an increase inpaediatric asthma A&E visits on the following day. The dust effect was strongly influenced by prevailing barometric pressure; heavy dust cover and low pressure were most strongly associated with increased acute asthma visits.

African dust clouds are associated with increased paediatric asthma accident and emergency admissions on the Caribbean island of Trinidad.

A retrospective ecological study of paediatric asthma patients who attended the Accident and Emergency (A and E) department of the Paediatric Priority Care Facility at the Eric Williams Medical Sciences Complex in relation to Saharan dust visibility and other climatic variables for the period 23 May 2001 to 13 May 2002 was undertaken to determine if there is an association between paediatric A and E asthma visits and Saharan dust cloud cover. A Poisson regression model was used to determine the statistical relationship between acute paediatric asthma A and E visits and Saharan dust cover with and without other variables such as climatic parameters and month. During the study period, there were 2,655 A and E visits for acute asthma. There was an association between increased paediatric asthma admissions and increased Saharan dust cover. The best fitting model estimated that in one month, such as June, a deterioration of visibility due to increased Saharan dust cover from no dust (visibility =16 km) to very dusty (visibility =7 km) would increase a daily admission rate of 7.8 patients to 9.25 when climate variables such as barometric pressure and humidity were kept constant.
