One-year longitudinal evaluation of neuropsychiatric symptoms in Alzheimer's disease. The REAL.FR Study

Behavioral and Psychological Symptoms are major and frequent manifestations of Alzheimer's Disease (AD). The aim of the present study was to evaluate neuropsychiatric symptoms in the PHRC REAL.FR cohort (for Réseau sur la maladie d'Alzheimer Fran?ais) after one year of evolution. Four hundred and eighty two patients with mild and moderate AD were assessed. A majority of them had significant symptoms at inclusion (85.3 % of subjects with mild AD, 89.7% of patients with a moderate AD). Patients with mild AD had a significant increase of the Neuropsychiatric Inventory (NPI) frequency x severity scores for apathy and aberrant motor behavior. Patients with moderate AD had a significant increase of NPI disinhibition, aberrant motor behavior and sleep disorders scores. The variation of NPI total score at one year correlated positively with change in Zarit's caregiver burden score, independently of global cognitive evolution. After one year, a group of 54 patients were institutionalized in nursing home or long term care unit. When compared to non institutionalized patients, the institutionalized group was characterized at base line by a lower MMSE score, a higher Zarit caregiver burden score, and a higher NPI agitation and disinhibition scores.     

The role of intratumoral therapy with cisplatin/epinephrine injectable gel in the management of advanced squamous cell carcinoma of the head and neck

OBJECTIVE: To determine the safety and efficacy of targeted antitumor therapy with cisplatin/epinephrine injectable gel in patients with advanced squamous cell carcinoma of the head and neck. DESIGN: Two prospective, double-blind, placebo-controlled phase III trials of identical design. Crossover from blinded to open-label phase was permitted for patients with disease progression. SETTING: Tertiary referral centers in North America and Europe. PATIENTS: One hundred seventy-nine intensively pretreated patients with recurrent or refractory squamous cell carcinoma of the head and neck. INTERVENTION: Cisplatin/epinephrine injectable or placebo gel was administered by direct intratumoral injection; up to 6 weekly treatments. Dose was 0.25 mL of active or placebo gel per cubic centimeter of tumor up to 10 mL total. Patient benefit after local tumor control of the most symptomatic tumor was assessed by patients and physicians using the Treatment Goals Questionnaire. MAIN OUTCOME MEASURES: Local tumor response and patient benefit attributable to improvements in tumor-related symptoms. RESULTS: Combined results for the 178 patients with evaluable data in the 2 trials confirmed objective tumor responses in 35 (29%) of 119 patients, including 23 (19%) complete responses achieved with cisplatin/epinephrine gel, vs 1 (2%) of 59 for placebo (P<.001). Tumor response and patient benefit were significantly correlated (P=.006): 47% (17/36) of patients with target tumor responses achieved a rigorously defined benefit based on a prospectively selected treatment goal vs 15% (22/142) of nonresponders. CONCLUSION: Cisplatin/epinephrine injectable gel reduces tumor burden, ameliorates tumor symptoms, and provides a new therapeutic option for treating patients with squamous cell carcinoma of the head and neck.     

An examination of perceived stress in family caregivers of older adults with heart failure

This investigation evaluates the moderating influence of social support on the negative effects of stress for family caregivers and validates the Perceived Stress Scale as a standard of measurement. Seventy-five family caregivers to older adults with heart failure were interviewed in their homes about perceived stress, depressive symptoms, and social support after hospital discharge. The Perceived Stress Scale demonstrated internal consistency. Social support did not moderate the effects of stress on depressive symptoms. Lack of a significant association between salivary cortisol and the Perceived Stress Scale did not support testing of construct validity. Stress levels, however, frequently vary due to caregiving demands and additional influencing factors.     

Role of behavioural disturbance in the loss of autonomy for activities of daily living in Alzheimer patients

BACKGROUND: Cognitive impairment is associated with functional impairment in patients with Alzheimer's disease (AD). Behavioural disturbance is very common in these patients. Nevertheless, there has been very little research into the relations between behavioural disturbance and functional status in AD. The purpose of this study is to investigate the relationship between behavioural disturbance and functional status after taking account of cognitive impairment. MATERIAL AND METHODS: 579 patients were prospectively evaluated at 16 French hospitals, all referents for AD, and were diagnosed with possible or probable AD. These patients were assessed with NeuroPsychiatric Inventory (NPI), cognitive subscales of the Alzheimer's Disease Assessment Scale (ADAS-cog), Clinical Dementia Rating scale (CDR) and Instrumental Activities of Daily Living scale (IADL). RESULTS: The number of men with available data for IADL total score was too small to make any analysis. 'Group A' gathered 256 women for whom the relation between autonomy for Activities of Daily Living (ADL) and the other variables were determined. 'Group B', pooled 85 women for whom relations found were verified. Linear regression was used for the analysis. With age, cognitive impairment allows us to explain best (38%) the loss of autonomy for ADL. CONCLUSION: The role of behavioural disturbances in the loss of autonomy for ADL was not determinant in our study, whereas cognitive impairment and age were better able to determine the loss of autonomy for ADL. Further study is needed to explain the decline of functional status in AD patients.
