The known steroids 7 and 8 were also isolated. The crude extract and the isolated compounds were evaluated for their ability to inhibit the 3D7 strain of Plasmodium falciparum. Compounds 2, 3, and 8 showed potent activity while that of the crude extract was moderate. [less ▲]

Sociality increases risks of disease transmission as genetically related individuals live in a confined environment. Therefore, social insects developed specific defences against pathogens by showing hygienic behaviours such as the rejection of cadavers and other wastes. We investigated if the undertaking and waste management is actually an efficient way of increasing ants’ survival and of limiting pathogens transmission. First, we observed the survival curve of ant colonies that were prevented from rejecting their dead nestmates outside the nest. Colonies that were forced to keep their dead inside the nest showed increased mortality of both adults and larvae in comparison to control nests, confirming that undertaking is an effective way for improving colony’s survival. Then, we compared the rejection dynamics of single waste items (ant cadavers, preys and clay pellet) introduced into ant nests. Clay pellets were quickly rejected within 12 ± 4 minutes, cadavers were dumped outside after 139 ± 28 min and preys were eaten and rejected only after 17.3 ± 0.3 hours. Spatial localisation inside the nest also differs between different items, as most cadavers stayed far from ants’ aggregate and larvae while preys were long-eaten close to larvae and inside ants’ aggregate. These results show that cadavers and preys are managed differently before becoming contagious, thus preventing effectively pathogens transmission inside the nest. [less ▲]

Background: Divergences in cognitive disturbances in hypothyroidism reported in the literature are a result of a methodological bias. Methods: By using a precise methodology, we examined attention and executive functions in hypothyroidism, verified the presence of anxiety and depressive symptoms in hypothyroidism, and examined the possible link between these symptoms and the cognitive disturbances (searching for attentional bias for words with a negative emotional valence). We administered a battery of cognitive tests to 23 participants who had undergone thyroidectomy for thyroid carcinoma: for the first time in an euthyroid state, then 3 weeks later (still in the euthyroid state) to assess the test/retest effect, and finally 4 weeks later in an hypothyroid state. We compared their performance with that of a group of 26 control participants who were also administered the same cognitive tests, also 3 times. Results: In hypothyroidism, the thyroid participants were more anxious and depressed than the controls and presented attentional and executive disturbances that reflected general slowing and difficulties in using their capacities of inhibition. However, they did not exhibit an attentional bias for words with a negative emotional valence. Conclusions: Contrary to what was expected, symptoms of anxiety and not symptoms of depression interfered with the cognitive performance of participants in hypothyroidism. [less ▲]

Studied breathing patterns and hyperventilation symptoms in 80 adolescents and adults (aged 16-60 yrs) with mild to moderate asthma and 40 adolescents and adults (aged 16-60 yrs) with no asthma symptoms (healthy controls). Data on pulmonary function, ventilation and breathing pattern, and psychological symptoms were obtained by clinical observation and questionnaire. Asthmatic Ss were requested not to take bronchodilatation medications for 24-48 hrs prior to testing. The Anxiety Sensitivity Index-Revised (S. Taylor and Cox, 1998), the Self-Consciousness Scale-Revised (A. Fenigwstein et al, 1975), the State-Train Anxiety Inventory, the Nijmegen Questionnaire (P. van Doorn et al, 1982), the Sense of Coherence Scale (A. Antonovsky, 1987), the Positive and Negative Affect Schedule (D. Watson et al, 1988), the Beck Depression Inventory, and the Asthma Symptoms Checklist (R. A. Kinsman et al, 1973, revision by Brooks et al, 1989) were used. The results show that the asthmatic subjects have lower PetCO2 than normal subjects and that variables associated with lower PetCO2 include total volume, female gender, and negative affectivity. The results also show that female subjects and asthmatics have similar breathing patterns and compared to male subjects [less ▲]

Purpose: To our knowledge, no study has specifically assessed the time course of anxiety during radiotherapy (RT). The objective of this study was to assess anxiety time courses in patients with nonmetastatic breast cancer. Material and methods: This multicenter, descriptive longitudinal study included 213 consecutive patients with breast cancer who completed visual analog scales (VASs) assessing state anxiety before and after the RT simulation and the first and last five RT sessions. Results: Pre- and post-session anxiety mean levels were highest at the RT simulation (respectively, 2.9 ± 2.9 and 1.6 ± 2.5) and first RT session (respectively, 3.4 ± 2.9 and 2.0 ± 2.4), then declined rapidly. Clinically relevant mean differences (P1 cm on the VAS) between pre- and post-simulation/session VAS scores were found only for the RT simulation ( 1.3 ± 2.7; p < 0.001) and first RT session ( 1.4 ± 2.4; p < 0.001). Five percent to 16% of patients presented clinically relevant anxiety (pre- and post-simulation/session VAS scoresP4 cm) throughout treatment. Conclusions: To optimize care, RT team members should offer all patients appropriate information about treatment at the simulation, check patients’ understanding, and identify patients with clinically relevant anxiety requiring appropriate support throughout RT.

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.
