[Impact of music therapy on anxiety and depression for patients with Alzheimer's disease and on the burden felt by the main caregiver (feasibility study)]. / Intérêts de la musicothérapie sur l'anxiété, la dépression des patients atteints de la maladie d'Alzheimer et sur la charge ressentie par l'accompagnant principal (étude de faisabilité).

INTRODUCTION: The impact of music therapy on dementia care for patients with Alzheimer's disease (AD) is well-recognized. Music alters the different components of the disease through sensory, cognitive, emotional, behavioral and social impacts. The academic aspect of music therapy in this area was based on the fact that music can alter the various components of the overall evolution of this disease. We found around 10 case studies presenting various results from receptive music therapy sessions on patients with Alzheimer's disease. The results of these studies point out the interest of music therapy in the multidisciplinary care of Alzheimer's disease and its related syndromes. It has been deemed useful for significantly reducing the medication given to AD patients. A music therapy protocol, specifically tailored to the patient's needs has been shown to significantly reduce anxiety, depression and aggressiveness in patients suffering from Alzheimer's disease. This technique has also demonstrated its impact on helping AD patients recall their previous life experience. OBJECTIVE: To demonstrate the feasibility and to evaluate the impact of music therapy on anxiety and depression at the early to moderate stage of Alzheimer's disease and on the main caregiver burden. METHOD: Five outpatients suffering from early stage of Alzheimer's disease (MMS: 18-26) were prospectively included. They were living in Montpellier with a reliable caregiver. A weekly receptive music therapy session was delivered to patients over a 10-week period, according to the U method standardized protocol. This technique was based on the recommendations made by Gardner and Good relating to the importance given to an individualized choice of music. Instrumental tracks were selected from various music styles (classic, jazz, world music...) and were tailored to the patient's requirements. This individual session was always followed by an interview with the music therapist in order to allow the patient to express the emotions felt during the session and to stimulate the patient's cognitive functions by recalling memories and images from his past life experience. The main evaluation criterion was regular session attendance at the hospital. Secondary criteria were: anxiety score (Hamilton scale), depression score (Cornell scale) and the burden score felt by the main caregiver (Zarit scale). Evaluations took place at W1, W4 and W10. The score evolution on the Hamilton, Cornell and Zarit scales were tested using the Wilcoxon test on paired data. The significance threshold has conventionally been set at 5% for all tests used. The statistical analysis was done using the SAS software (8th version) (SAS Institute, Cary, N.C.; proc npar1way, proc univariate, proc freq). Alzheimer's disease is a recognized indication for music therapy. A simple oral consent was collected prior to the study inclusion. RESULTS: Five patients were included for a total of 44 sessions. The patients' regular attendance at the music therapy sessions showed its feasibility. Thanks to oral feedback, we were able to see that music therapy was very well-accepted both by patients and caregivers. After the sessions, all patients expressed a sensation of well-being and pleasure, such as: "Music made me feel better, I feel more relaxed", "I feel better", "I didn't know that music could have such an impact on me"... Other verbal comments were collected regarding the patients' previous life experience: "This music reminds me of my childhood", "I imagined myself dancing just like I used to in the old days", "This reminds me of my trip to Italy with my children"... The level of anxiety (Hamilton scale) dropped significantly from 9.4 (+/-2.2) to 3.4 (+/-2.6) between the first session and the fourth session (P<0.004). The differences observed between W4-W10 and W1-W10 were close to the threshold of significance due to a major drop in the anxiety level starting at W4 (P=NS). On the Cornell scale, the depression level dropped significantly from 10.8 (+/-5.3) to 2.2 (+/-1.9) between the first session and the fourth session (P<0.01). The differences observed between W4-W10 and W1-W10 were not significant (P=NS). The weight of the physical and emotional burden experienced by the main caregiver (Zarit scale) fell significantly from 30.2 (+/-11.7) to 15.6 (+/-10.4) between W1-W4 (P<0.002). The differences observed between W4-W10 and W1-W10 were not significant (P=NS). DISCUSSION/CONCLUSION: This preliminary study demonstrates the feasibility as well as the initial efficacy of music therapy in terms of its impact on the overall care for patients suffering from Alzheimer's disease. This easily applicable technique can be useful in treating anxiety and depression in a patient with Alzheimer's disease and also in relieving the emotional and physical burden experienced by the main caregiver.

Additional direct medical costs of nosocomial infections: an estimation from a cohort of patients in a French university hospital.

We estimated the direct additional medical costs of nosocomial infections (NI) using a cohort study in acute and longer-term care at Nîmes University Hospital in France. Patients hospitalised between May 2001 and January 2003 with NI were considered as exposed; all others were eligible as non-exposed. Thirty patients were randomly chosen for each site of infection: respiratory tract, bloodstream, surgical site, urinary tract and other sites for a total of 150 exposed patients. Each exposed patient was matched with a non-exposed patient according to gender, age, severity of the underlying disease, diagnosis according to hospital discharge records, ward type and length of hospitalisation before inclusion. Additional direct medical costs for the exposed patients compared to the non-exposed and the difference between actual costs and the diagnosis-related group rate were measured. Costs resulting from laboratory tests, radiology, surgery and exploratory examinations, and antimicrobial agents were estimated to be Euro2421 for a respiratory tract infection, Euro1814 for a surgical site infection, Euro953 for a bloodstream infection and Euro574 for a urinary tract infection. Total additional costs of NI (direct medical costs and costs of extra length of stay) in acute care were estimated to be up to Euro3.2 million per year (95% confidence interval: 2,275,063-4,132,157). In conclusion, both prevention of avoidable NI and better estimation of the actual costs of NI should be priorities for all healthcare facilities.

Mortality attributable to nosocomial infection: a cohort of patients with and without nosocomial infection in a French university hospital.

OBJECTIVE: To assess nosocomial infection (NI) as a risk factor for death and to estimate the population-attributable risk of death from NI. DESIGN: A prospective cohort study of patients with and without NI. SETTING: Nimes University Hospital, Nimes, France. PATIENTS: Patients were recruited from May 7, 2001, to January 10, 2003. Patients in acute care and long-term care units who had NI were enrolled, and patients without NI were randomly selected and matched with patients with NI for age, sex, type of care (acute care vs. long-term care) and length of stay in hospital at study inclusion. OUTCOME MEASURES: Vital status within 60 days after study inclusion was assessed. We used conditional logistic regression to estimate the relative death risk from NI after adjusting for comorbidities, severity of the underlying disease, and all other confounding factors. The adjusted population-attributable risk was assessed using the Mantel-Haenszel method. RESULTS: We recruited 1,914 patients with NI and 5,172 patients without NI. The median age of the patients with NI was 73 years; 1,045 (54.6%) were female. NI was associated with death within 60 days (adjusted odds ratio, 1.7 [95% confidence interval {CI}, 1.4-;2.2]; P<.001). The adjusted population-attributable risk of death for all sites of infection was 1.7% (95% CI, 1.4-2.1). If we consider the NI incidence to be 3%-6% in French hospitals, the population-attributable risk of death from NI would range from 2.1% (95% CI, 1.7%-2.5%) to 4.0% (95% CI, 3.3%-4.9%). CONCLUSION: In this study, NI appeared to have a significant impact on mortality. Multicenter studies will be needed to confirm these results.

[Prevention of skin cancer programs: analysis of the impact of randomized trials]. / Programmes de prévention des cancers cutanés. Analyse de l'impact des études randomisées.

INTRODUCTION: Exposure to ultraviolet sun rays is an important risk factor for the development of skin cancer. Confronted with the increase in the incidence of severe forms (melanoma), primary prevention plays a major part, together with the development of campaigns promoting individual and collective protection against ultraviolet rays. OBJECTIVE: The aim of this trial was to identify the factors of success or failure of skin cancer prevention programs and to analyze their impact. METHOD: Articles published in the literature from 1982 to 2002 were selected from the Medline databank using the following key words: "skin cancer, melanoma, evaluation, prevention and education, review, program, campaign and randomized controlled trial". For the final analysis, only the randomized trials with control group were retained. RESULTS: All the prevention programs increased short, median or long term knowledge. Conversely, the trials were sometimes contradicting with regard to the change in attitude. No methodologically correct trial clearly reported any change in behavior, the majority of them only collected intent behavior. CONCLUSION: Despite the methodological weaknesses of most of the trials published, this review of the literature underlined certain points. The most efficient programs appear to be those targeting children, the training sessions of which are long and/or repeated, with active individual participation. Programs based on the deleterious consequences of sun exposure on physical appearance appeared to produce better results in terms of any change in attitude and intent behavior.

Risk factors for multidrug-resistant Pseudomonas aeruginosa nosocomial infection.

A case-control study was conducted in a university hospital to determine the risk factors for nosocomial infection with multidrug-resistant Pseudomonas aeruginosa (MDR-PA) among all hospitalized patients and among those with a nosocomial infection due to P. aeruginosa. Eighty patients infected with MDR-PA, 75 infected with a non-MDR phenotype and 240 random controls were included in the 12-month study. Among all hospitalized patients, age, severity index, having a bedridden condition, transfer from other units, nasogastric feeding, urinary catheterization and exposure to beta-lactams (OR=2.5) or fluoroquinolones (OR=4.1) in the seven days before infection were linked to nosocomial infection due to MDR-PA. Among patients infected by P. aeruginosa, exposure to fluoroquinolones (OR=4.7) or surgery (OR=0.5) were linked to the isolation of MDR-PA. This study showed that, in addition to urinary catheterization, nasogastric feeding is an important risk factor in MDR-PA infection. Indeed, an imbalance in gut flora, modifications to the mucous membranes due to the use of nasogastric feeding and the selection pressures exerted by antibiotics were implicated in the occurrence of this infection.

Evaluation of imipenem 1.5 g daily in febrile patients with short duration neutropenia after chemotherapy for non-leukemic hematologic malignancies and solid tumors: personal experience and review of the literature.

Numerous studies have demonstrated efficacy of imipenem-cilastatin, 50 mg/kg/day, as first line therapy in febrile patients with neutropenia of short duration consecutive to cytostatic chemotherapy. However, only two studies used low dosage of this antibiotic as 1.5 g/day, in prospective, double blind, randomized clinical trials, in this indication. Efficacy and tolerability of imipenem-cilastatin 0.5 g three times daily IV in 30-min infusions, as first-line empiric therapy, were retrospectively evaluated in our hematological unit. From January 1996 to September 2000, 30 neutropenic patients (12 females) with 45 febrile episodes were included. Median age was 57.5 years (31-75). Twenty-four of them had lymphomas, 4 solid tumors and 2 myelomas. There were 13 clinically documented infections, (CD, 28.8%), 16 microbiologically documented infections, (MD, 35.6%) and 16 febrile episodes corresponding to fever of unknown origin, (FUO, 35.6%). The median neutrophils count on nadir (n = 44), was 67/mm3 (8-369). The median duration of neutropenia was 5 days (3-15). Bacteremia was observed in 10 patients, urinary tract infection in 3 patients. The most frequently isolated microorganism was Escherichia coli. The overall success rate of the first line therapy was 66.7%. Adverse events were observed in 11.1% of the patients without necessity to stop treatment. The MD infections showed a lower rate of success compared with CD infections and FUO. These data were in accordance with the previous studies. The importance of number of microorganisms (p = 0.007) and of infected sites (p = 0.01) appeared as prognostic factors (univariate analysis). Although imipenem-cilastatin has been used in numerous studies as empiric broad-spectrum antibiotic therapy in the treatment of febrile neutropenic cancer patients, the exact dosage of this antibiotic is still not standardized. However, utilization of this antibiotic in monotherapy at low dosage seems to us to be safe and effective as usual dosage in the antimicrobial treatment ofthe febrile patients with post chemotherapy neutropenia of short duration.
