BACKGROUND AND PURPOSE: Patients may experience clinically relevant anxiety at their first radiotherapy (RT) sessions. To date, studies have not investigated during/around the RT simulation the key communication and communication-related predictors of this clinically relevant anxiety. MATERIAL AND METHODS: Breast cancer patients (n=227) completed visual analog scale (VAS) assessments of anxiety before and after their first RT sessions. Clinically relevant anxiety was defined as having pre- and post-first RT session VAS scores 4cm. Communication during RT simulation was assessed with content analysis software (LaComm), and communication-related variables around the RT simulation were assessed with questionnaires. RESULTS: Clinically relevant anxiety at the first RT session was predicted by lower self-efficacy to communicate with the RT team (OR=0.65; p=0.020), the perception of lower support received from the RT team (OR=0.70; p=0.020), lower knowledge of RT-associated side effects (OR=0.95; p=0.057), and higher use of emotion-focused coping (OR=1.09; p=0.013). CONCLUSIONS: This study provides RT team members with information about potential communication strategies, which may be used to reduce patient anxiety at the first RT session. [less ▲]

Epidemiologic studies suggested a possible link between prenatal exposure to organophosphate insecticides (OP) and long-term mental delay and some behavioral troubles. Experimental studies in rats and mice have confirmed that a relatively short exposure to low doses of OP such as chlorpyrifos (CPF) during specific perinatal periods decreased anxiety-like behaviors. In the present study, we report that chronic perinatal exposure (GD15-PND14) to low doses of CPF leads to an increase (and not a decrease) in anxiety-like behaviors of female mouse offspring. Pregnant or lactating female mice were exposed to CPF (0.2; 1; or 5 mg/kg day) by oral treatment during 18 consecutive days. Following a recovery period of several weeks, the anxiety of adult female offspring was determined using neurobehavioral tests (elevated plus-maze and light/dark box tests). Our results showed that CPF-exposed female offspring were more anxious than controls. In addition, the magnitude of anxiety profile alterations depended on the level of exposure to CPF during gestation and lactation with a maximal effect observed at the 1 mg/kg day dose. Our results confirm that OP exposure during the perinatal period can induce long-term alterations in mouse anxiety-like behaviors and suggest that the routes of administration and the duration of OP exposure during brain development may be factors to consider when studying the development of anxiety.

Introduction. Anxiety sensitivity (AS) is the fear of anxiety-related sensations due to beliefs that these sensations will lead to physical illness, social embarrassment, loss of control and mental incapacitation. AS plays a central role in the etiology and maintaining of fear and anxiety. This work examines the gender and age effect on the AS scores. Method. Two hundred children aged 9 to 13 years completed the Childhood Anxiety Sensitivity Index (CASI). Results. Hierarchical multiple regression analyses showed that the sex and the interaction Sex*Age explain significantly the CASI scores. The interaction indicated that girls have higher AS than boys at the age of 9, 10 and 11 but not to 12 and 13 years. Discussion. Consistent with several studies, girls have higher CASI scores than boys. However, this difference disappears at the entrance of adolescence. This developmental observation is important in a prevention perspective of AS. [less ▲]

Recently acquired data question the sharp dichotomy between anxiolytics and neuroleptics, since disinhibitory effects have been measured in the rat with very low doses of haloperidol and higher doses of atypical neuroleptics in FI and DRL schedules, but also in the open-field test. That the DA transmission in certain brain regions is involved in some aspects of anxiety has recently been suggested. The present study confirms this hypothesis particularly with high doses of sulpiride (80 mg/kg) and clozapine (24 mg/kg) when tested in the open-field test. Moreover, the results show how a slight chemical modification of clozapine can give a direction to pharmacological activity with one derivative still resembling clozapine and the second one resembling haloperidol. As neuroleptics do not seem to influence the synthesis and utilization of GABA, the higher entry score observed with them would seem to depend above all on DA antagonism in the mesolimbic system.

Abstract Background and aims The relations between tree species, microbial diversity and activity can alter ecosystem functioning. We investigated ammonia oxidizing bacteria (AOB) community structure and richness, microbial/environmental factors related to AOB diversity and the relationship between AOB diversity and the nitrification process under several tree species. Methods Forest floor (Of, Oh) was sampled under European beech, sessile oak, Norway spruce and Douglas-fir at three sites. AOB community structure was assessed by PCR-DGGE and sequencing. Samples were analyzed for net N mineralization, potential nitrification, basal respiration, microbial biomass, microbial or metabolic quotient, pH, total nitrogen, extractable ammonium, organic matter content and exchangeable cations. Results AOB community structure and tree species effect on AOB diversity were site-specific. AOB richness was not related to nitrification. Factors regulating ammonium availability, i.e. net N mineralization or microbial biomass, were related to AOB community structure. Conclusion Our research shows that, at larger spatial scales, site specific characteristics may be more important than the nature of tree species in determining AOB diversity (richness and community structure). Within sites, tree species influence AOB diversity. The absence of a relation between AOB richness and nitrification points to a possibly role of AOB abundance, phenotypic plasticity or the implication of ammonia oxidizing archaea. [less ▲]

The synthesis and deposition of collagen and other proteins has been measured in the aorta of the rat by radiolabeling in short term organ culture. Under these conditions, the synthesis of collagen and other proteins is linear for at least five hours. Autoradiography demonstrates a labeling in all cell layers and protein deposition in the extracellular matrix. Hypertension was induced by renal ischemia using Goldblatt's technique. The synthesis and deposition of collagen was stimulated in aorta from the first week of hypertension and in pregnancy, and was even more increased in hypertensive pregnant animals. Reserpine suppresses the rise in blood pressure in operated animals and prevents these modifications. [less ▲]

OBJECTIVES: To determine long-term results of aortic valve replacement (AVR) in patients 80 years old or older, and assess the factors influencing perioperative outcome. METHODS: Data were reviewed on 83 consecutive octogenarians, undergoing aortic valve replacement between 1992 and 1997. There were 66 women and 17 men (mean age: 82.8 years). Fifty-seven patients (69%) were in New York Heart Association (NYHA) class III-IV and six had previous myocardial infarction. Three patients had previous percutaneous aortic valvuloplasty. There were 19 urgent procedures (23%). Coronary artery bypass grafting (CABG) was performed on 21 patients (25%). Possible influence of preoperative and operative variables on early and late mortality was performed with univariate and multivariate statistical analysis, and survival was estimated with the Kaplan-Meier method. RESULTS: Operative mortality was 13% (9% for AVR, 24% for AVR-CABG). Postoperative complications were respiratory failure in 19 patients, atrial fibrillation in 19, hemodialysis in four, myocardial infarction in four and stroke in two patients. Five patients required pacemaker insertion for permanent atrioventricular block. Median hospital stay and intensive care unit stay were 19.8 +/- 12.2 days and 7.9 +/- 3.4 days, respectively. Multivariate predictors of hospital death (P < 0.05) were percutaneous aortic valvuloplasty, NYHA class IV, and urgent procedure. Mean follow-up was 26.5 months. Survival at 1, 2, and 5 years was 98.5 +/- 1.4% (63 patients at risk), 93.4 +/- 3.2% (47 patients at risk), and 78.2 +/- 6.9% (six patients at risk), respectively. Preoperative myocardial infarction and urgent procedure were independent predictors of late death. At most recent follow-up, 91% were angina free and 81% were in class I-II. CONCLUSIONS: Aortic valve replacement in octogenarians can be performed with acceptable mortality. These results stress the importance of early operation on elderly patients with aortic valve disease. Both long-term survival and functional recovery are excellent. [less ▲]

Objective: To assess factors influencing operative and tong-term outcome in octogenarians undergoing aortic valve surgery (AVR). Methods: Records of 220 consecutive octogenarians having AVR between 1992 and 2004 were reviewed, and follow-up obtained (99% complete). Of the group (mean age: 82.8 years; 174 females), 142 patients (65%) were in New York Heart Association (NYHA) class III-IV, 22 (10%) had previous myocardial infarction, 11 (5%) had previous coronary artery bypass grafting (CABG), and 8 (4%) had percutaneous aortic valvuloplasty. There were 44 urgent procedures (20%), and additional CABG was performed in 58 patients (26%). Results: Operative mortality was 13% (9% for AVR, 24% for AVR + CABG). Among the 29 patients who died, 14 (48%) were operated on urgently (32% mortality for urgent procedures). Causes of hospital death were respiratory insufficiency or infection in 16 patients (16/29 = 55%), myocardial, infarction in 8 (28%), stroke in 2 (7%), sepsis in 2 (7%), and renal failure in 1 (3%). Significant postoperative complications were atrial fibrillation in 48 patients (22%), respiratory insufficiency in 46 (21%), permanent atrio-ventricular bloc in 12 (5%), myocardial infarction in 10 (5%), hemodialysis in 4 (2%), and stroke in 4 (2%). Mean hospital and intensive care unit (ICU) stays were 17.6 +/- 5.2 and 6.9 +/- 3.4 days, respectively. Multivariate predictors (p < 0.05) of hospital death were urgent procedure, associated CABG, NYHA class IV, and percutaneous aortic valvuloplasty. Age, associated CABG, and urgent procedure were predictors of prolonged ICU stay. Mean follow-up was 58.2 months and actuarial 5-year survival was 73.2 +/- 6.9%. Age, preoperative myocardial infarction, urgent procedure, and duration of ICU stay were independent predictors of late death. Among 130 patients alive at follow-up, 91% were angina free and 81% in class I-II. Conclusions: AVR in octogenarians can be performed with acceptable mortality, although significant morbidity. These results stress the importance of early operation on elderly patients with aortic valve disease, avoiding urgent procedures. Associated coronary artery disease is a harbinger of poor operative outcome. Long-term survival and functional recovery are excellent. (c) 2007 European Association for Cardio-Thoracic Surgery.
