Somnambulism induced by quetiapine: two case reports and a review of the literature

Somnambulism, a previously unreported side effect of quetiapine, is described in two cases. Both cases involved individuals who had no prior or family history of somnambulism and had attention-deficit/hyperactivity disorder. The possible significance of this will also be discussed. Somnambulism is a common parasomnia that reflects an impairment in the normal mechanisms of arousal from sleep in which motor behaviors are activated without full consciousness. Motor behaviors are initiated during deep non-rapid eye movement or slow-wave sleep (stages 3-4), and may be limited to relatively simple manifestations, such as sitting up, fumbling with objects or bedclothes, or mumbling.     

Gender gaps in cognitive and social‐emotional skills in early primary grades: Evidence from rural Indonesia

This paper examines the magnitude and source of gender gaps in cognitive and social‐emotional skills in early primary grades in rural Indonesia. Relative to boys, girls score more than 0.17 SD higher in tests of language and mathematics (cognitive skills) and between 0.18 and 0.27 SD higher in measures of social competence and emotional maturity (social‐emotional skills). We use Oaxaca–Blinder decomposition to investigate the extent to which gender differences in early schooling and parenting practices explain these gender gaps in skills. For cognitive skills, differences in early schooling between boys and girls explain between 9% and 11% of the gender gap whereas differences in parenting practices explain merely 3%–5% of the gender gap. This decomposition result is driven largely by children living in villages with high‐quality preschools. In contrast, for social‐emotional skills, differences in parenting styles toward boys and girls explain between 13% and 17% of the gender gap, while differences in early schooling explain only 0%–6% of the gender gap.     

Different Types of Religiosity and Lay Intuitions About Free Will/Determinism in Turkey

Religiosity has been found to be positively associated with belief in free will (FW) in the Western world. In the Muslim world, however, religiosity exhibits several characteristics that set it apart from the Western world, including an overemphasis on fate or divine predestination. We, therefore, investigated FW/determinism beliefs and different types of religiosity and conservatism in two samples in Turkey, a predominantly Muslim country (N = 1,690). In Study 1, a confirmatory factor analysis showed that FAD-Plus provided good fit to the data. Study 2 revealed that FW belief is not related to any of the religiosity measures (intrinsic, extrinsic, quest), whereas fatalistic determinism is consistently related to religiosity. The unique predictor of free will turned out to be belief in a just world. Overall, these findings indicate that FW belief is not inherently related to religiosity in Turkey, whereas fatalistic determinism is central to Turkish people’s belief systems.     

A cross-modal effect of noise: the disappearance of the alarm reaction of a freshwater fish

Anthropogenic noise pollution is recognized as a major global stressor of animals. While many studies have assessed the unimodal impacts of noise pollution with a focus on intraspecific acoustic communication, little is known about noise pollution on the perception of visual and chemical information. The ‘distracted prey hypothesis’ posits that processing noise interferes with processing other information in the brain. Here, we found evidence for such a cross-modal effect of noise on the antipredator behaviour of a freshwater prey fish, the fathead minnow, Pimephales promelas. In laboratory trials, exposure to noise from a motorboat caused the total absence of the classical fright reaction of minnows to conspecific alarm cues, whereas an ambient noise control had no such impact. In natural habitats, the impairment of such antipredator behaviour due to noise pollution could have major fitness consequences. We discuss how our findings translate to animal ecology and the need for future studies that target specific management decisions regarding noise pollution.     

Accenting and detection of timing variations in tone sequences: Different kinds of accents have different effects

The effect of intensity and pitch accents on the perception of timing was examined in two experiments using a signal detection procedure. Analyses of sensitivity and response bias revealed opposite effects of intensity and pitch accents under similar conditions. Time intervals preceding intensity accents were perceived as longer, but time intervals preceding pitch accents were perceived as shorter. These results showed that listeners found it easier to detect timing variations that were contrary to expectations, as compared with variations that were consistent with expectations. In the present case, listeners should have expected shorter time intervals before intensity accents and longer intervals before pitch accents. The fact that the effects were observed with stimuli that had minimal musical structure demonstrated the contribution of psychoacoustic factors to such phenomena.     

Trauma in Resettled Iraqi Refugees: Differences between Those Seeking Psychological Treatment and Those Not Seeking Psychological Treatment

Psychological distress experienced by resettling refugees has been well documented, with posttraumatic stress disorder (PTSD) and depression being prevalent outcomes. This study examined psychological and physiological measures of trauma exposure in 2 groups of Iraqi refugees resettled in Australia, those seeking psychological treatment (n = 25) versus those not seeking treatment (n = 22). Data from a group of healthy sex- and age-matched controls (n = 32) were collected to facilitate norm comparisons for physiological arousal. Continuous recording of electrocardiogram data examined resting heart rate (HR). Refugees seeking treatment had significantly higher levels of PTSD symptomology and depression levels compared to non-treatment-seeking refugees; however, there was no difference in the number of trauma events endorsed. Finally, resting HR was significantly higher in both refugee groups compared with healthy controls; however, there was no difference between the refugee groups. Clinical consideration of this excessive trauma exposure and elevated autonomic arousal is warranted.     

The Impact of Religious Connectedness on Health-Related Quality of Life in Patients with Diabetic Foot Ulcers

Religious connectedness is common phenomenon in Saudi Arabia and adjacent Gulf countries. An observational case control study was designed, enrolling 180 adult patients to report the association between religious connectedness and health-related quality of life (HRQL) in people with and without diabetes and foot ulcers. Sixty diabetic patients with foot ulcers (Group I) were compared with sixty diabetic patients without foot ulcer (Group II) and sixty healthy subjects (Group III) for assessment of their HRQL by using SF-36 questionnaire. The effect of religious connectedness was assessed using intrinsic/extrinsic religious connectedness scale. HRQL was found to be significantly lower in Group I compared with Group II and III as well as in group II compared with group III (P < 0.001). Group I patients showed a poorer HRQL with increased severity, duration and multiplicity of foot ulcers. There was a strong positive relationship between religious connectedness and HRQL as indicated by a positive correlation between religious connectedness scale and mental, physical component summary scores (r = 0.66 and 0.59 respectively and P < 0.001). While quality of life is generally poor in people with diabetic foot ulcers, there exists a strong positive relationship between religious connectedness and higher HRQL. These findings may have implications on improving outcomes.     

Prevalence of anxiety among patients undergoing colorectal surgery

To assess prevalence of anxiety 36 consecutive patients undergoing colorectal surgery with general anesthesia were interviewed on the day of surgery and completed the State-Trait Anxiety Inventory. Postsurgical ratings of pain and anxiety were obtained within 24 hours after surgery. Analysis indicated that 29 scored moderate or higher on the State Anxiety scale prior to surgery. The correlations for scores on presurgical Trait Anxiety with postsurgical pain and Trait Anxiety scores were significant (p<.01) but not that for pre- and postsurgical State Anxiety     

Complementary and alternative medicine use by psychiatric inpatients

82 psychiatric inpatients hospitalized for acute care were interviewed about their use of complementary and alternative medicine (CAM) modalities. The clinical diagnoses of respondents included Depressive Disorder (61%), Substance Abuse (26%), Schizophrenia (9%), and Anxiety Disorders (5%). Analysis indicated that 63% used at least one CAM modality within the previous 12 mo. The most frequently used modality was herbal therapies (44%), followed by mind-body therapies such as relaxation or mental imagery, hypnosis, meditation, biofeedback (30%), and spiritual healing by another (30%). Physical modalities such as massage, chiropractic treatment, acupuncture, and yoga were used by 21% of respondents. CAM therapies were used for a variety of reasons ranging from treatment of anxiety and depression to weight loss. However, most respondents indicated they did not discuss such use with their psychiatrist or psychotherapist.
