Evaluation of Excessive Daytime Sleepiness with Sleep Apnea and Determining the Relationship Between Life Quality

Aim:Obstructive Sleep Apnea syndrome (OSAS) is an important health issue characterized by repetitive episodes of upper airway obstruction affecting many different systems in the human body. In this study, we aimed to examine the relationship of daytime sleepiness with quality of life in patients with OSAS.Methods:In this study, adult patients, who underwent diagnostic polysomnography for the first time in our clinic, were included. Data on physical examination findings and demographic characteristics were recorded. The Epworth Sleepiness Scale, 36-Item Short Form Health Survey (SF-36), Beck Anxiety Inventory, and the Beck Depression Inventory were administered to the patients.Results:A total of 136 patients with the mean age of 45.5±9.7 (22- 68) were included in the study. Thirty four patients were (25%) female and 102 were male (75%). Simple snoring was detected in 30 patients (22.1%), mild OSAS in 24 patients (17.6%), moderate OSAS in 26 patients (19.1%) and severe OSAS was found in 56 patients (42.1%). Epworth Sleepiness Scale scores in patients with severe OSAS were statistically significantly higher than in other patients. The lowest SF-36 scores were observed in severe OSAS patients.Conclusion:The quality of life was significantly decreased in patients with severe OSAS. We assume that quality life was negatively correlated Epworth Sleepiness Scale scores

Differential association between MAOA, ADHD and neuropsychological functioning in boys and girls

Contains fulltext : 70148.pdf (publisher's version ) (Closed access)Attention-deficit/hyperactivity disorder (ADHD) is more common in boys than in girls. It has been hypothesized that this sex difference might be related to genes on the X-chromosome, like Monoamine Oxidase A (MAOA). Almost all studies on the role of MAOA in ADHD have focused predominantly on boys, making it unknown whether MAOA also has an effect on ADHD in girls, and few studies have investigated the relationship between MAOA and neuropsychological functioning, yet this may provide insight into the pathways leading from genotype to phenotype. The current study set out to examine the relationship between MAOA, ADHD, and neuropsychological functioning in both boys (265 boys with ADHD and 89 male non-affected siblings) and girls (85 girls with ADHD and 106 female non-affected siblings). A haplotype was used based on three single nucleotide polymorphisms (SNPs) (rs12843268, rs3027400, and rs1137070). Two haplotypes (GGC and ATT) captured 97% of the genetic variance in the investigated MAOA SNPs. The ATT haplotype was more common in non-affected siblings (P = 0.025), conferring a protective effect for ADHD in both boys and girls. The target and direction of the MAOA effect on neuropsychological functioning was different in boys and girls: The ATT haplotype was associated with poorer motor control in boys (P = 0.002), but with better visuo-spatial working memory in girls (P = 0.01). These findings suggest that the genetic and neuropsychological mechanisms underlying ADHD may be different in boys and girls and underline the importance of taking into account sex effects when studying ADHD

Eye Movements to Natural Images as a Function of Sex and Personality

Women and men are different. As humans are highly visual animals, these differences should be reflected in the pattern of eye movements they make when interacting with the world. We examined fixation distributions of 52 women and men while viewing 80 natural images and found systematic differences in their spatial and temporal characteristics. The most striking of these was that women looked away and usually below many objects of interest, particularly when rating images in terms of their potency. We also found reliable differences correlated with the images ’ semantic content, the observers’ personality, and how the images were semantically evaluated. Information theoretic techniques showed that many of these differences increased with viewing time. These effects were not small: the fixations to a single action or romance film image allow the classification of the sex of an observer with 64 % accuracy. While men and women may live in the same environment, what they see in this environment is reliably different. Our findings have important implications for both past and future eye movement research while confirming the significant role individual differences play in visual attention

Psychometric properties and factor structure of the Temperament and Character Inventory-Revised (TCI-R) in a Croatian psychiatric outpatient sample

OBJECTIVE: The goal of this study was to investigate psychometric properties and factorial structure of the Croatian adaptation of the Temperament and Character Inventory-Revised (TCI-R) in a sample of psychiatric outpatients (n=328). ----- METHOD: The participants filled out the TCI-R, as well as self-report measures of the Big-Five personality traits (IPIP-50), trait impulsivity (BIS-11), depression (BDI-II), suicidality (SBQ-R), and life satisfaction (SWLS). We explored the internal consistency of 7 domains and 29 subscales and compared it with the Croatian version of the original TCI used in prior studies. Principal component analysis with promax rotation was conducted on temperament and character subscales separately, while concurrent validity was examined through the TCI-R's relations with the abovementioned psychological measures. ----- RESULTS: The TCI-R scales showed adequate internal consistencies, with Cronbach's alpha values ranging from 0.77 to 0.93. The internal consistency showed to be higher in comparison with the Croatian version of the original TCI. The postulated four-factor structure of temperament and the three-factor structure of character were confirmed. The meaningful associations with other measures supported the concurrent validity of the TCI-R. ----- CONCLUSION: The Croatian adaptation of the TCI-R exhibited satisfactory reliability and validity in a sample of psychiatric outpatients. These findings support the use of the TCI-R in Croatian clinical settings over its predecessor (TCI)

Prenatal antidepressant exposure and child behavioural outcomes at 7 years of age: a study within the Danish National Birth Cohort

Objective: To investigate the impact of prenatal antidepressant exposure on behavioural problems in children at 7 years of age. Design: Nationwide population-based study. Setting: Danish National Birth Cohort. Population: A cohort of 49 178 pregnant women recruited between 1996 and 2002. Methods: Data obtained from computer-assisted telephone interviews twice during pregnancy were used to identify children born to: (i) depressed women who took antidepressants during pregnancy (n = 210); (ii) depressed women who did not take any antidepressants during pregnancy (n = 231); and (iii) healthy women who were not depressed (n = 48 737). Childhood behavioural problems at 7 years of age were examined using the validated Danish parent-report version of the Strengths and Difficulties Questionnaire (SDQ). Main outcome measures: SDQ scores. Results: No associations were observed between prenatal antidepressant exposure and abnormal SDQ scores for overall problem behaviour (adjusted relative risk, aRR 1.00; 95% confidence interval, 95% CI 0.49–2.05), hyperactivity/inattention (aRR 0.99; 95% CI 0.56–1.75), or peer problems (aRR 1.04; 95% CI 0.57–1.91). Although prenatal antidepressant exposure appeared to be associated with abnormal SDQ scores on the subscales of emotional symptoms (aRR 1.68; 95% CI 1.18–2.38) and conduct problems (aRR 1.58; 95% CI 1.03–2.42), these associations were significantly attenuated following adjustment for antenatal mood status (aRR 1.20; 95% CI 0.85–1.70 and aRR 1.19; 95% CI 0.77 1.83, respectively). Untreated prenatal depression was associated with an increased risk of all behavioural outcomes evaluated, compared with unexposed children, with significant attenuation following adjustment for antenatal mood status. Conclusions: The results of this study suggest that independent of maternal illness, prenatal antidepressant exposure is not associated with an increased risk of behavioural problems in children at 7 years of age.LE Grzeskowiak, JL Morrison, TB Henrikse, BH Bech, C Obel, J Olsen, LH Pederse

Sex as a Biological Variable in Emergency Medicine Research and Clinical Practice: A Brief Narrative Review.

The National Institutes of Health recently highlighted the significant role of sex as a biological variable (SABV) in research design, outcome and reproducibility, mandating that this variable be accounted for in all its funded research studies. This move has resulted in a rapidly increasing body of literature on SABV with important implications for changing the clinical practice of emergency medicine (EM). Translation of this new knowledge to the bedside requires an understanding of how sex-based research will ultimately impact patient care. We use three case-based scenarios in acute myocardial infarction, acute ischemic stroke and important considerations in pharmacologic therapy administration to highlight available data on SABV in evidence-based research to provide the EM community with an important foundation for future integration of patient sex in the delivery of emergency care as gaps in research are filled

TPH2 Deficiency Influences Neuroplastic Mechanisms and Alters the Response to an Acute Stress in a Sex Specific Manner

Dysregulations of the central serotoninergic system have been implicated in several psychopathologies, characterized by different susceptibility between males and females. We took advantage of tryptophan hydroxylase 2 (TPH2) deficient rats, lacking serotonin specifically in the brain, to investigate whether a vulnerable genotype can be associated with alterations of neuronal plasticity from the early stage of maturation of the brain until adulthood. We found a significant increase, in both gene and protein expression, of the neurotrophin brain-derived neurotrophic factor (BDNF), in the prefrontal cortex (PFC) of adult TPH2-deficient (TPH2-/-) male and female rats in comparison to wild type (TPH2+/+) counterparts. Interestingly, a development-specific pattern was observed during early postnatal life: whereas the increase in Bdnf expression, mainly driven by the modulation of Bdnf isoform IV was clearly visible after weaning at postnatal day (pnd) 30 in both sexes of TPH2-/- in comparison to TPH2+/+ rats, at early stages (pnd1 and pnd10) Bdnf expression levels did not differ between the genotypes, or even were downregulated in male TPH2-/- animals at pnd10. Moreover, to establish if hyposerotonergia may influence the response to a challenging situation, we exposed adult rats to an acute stress. Although the pattern of corticosterone release was similar between the genotypes, neuronal activation in response to stress, quantified by the expression of the immediate early genes activity regulated cytoskeleton associated protein (Arc) and Fos Proto-Oncogene (cFos), was blunted in both sexes of animals lacking brain serotonin. Interestingly, although upregulation of Bdnf mRNA levels after stress was observed in both genotypes, it was less pronounced in TPH2-/- in comparison to TPH2+/+ rats. In summary, our results demonstrated that serotonin deficiency affects neuroplastic mechanisms following a specific temporal pattern and influences the response to an acute stress
