Circadian Rhythm Sleep Disorders

The circadian rhythm sleep disorders define the clinical conditions where sleep and ndash;wake rhythm is disrupted despite optimum environmental and social conditions. They occur as a result of the changes in endogenous circadian hours or non-compatibility of environmental factors or social life with endogenous circadian rhythm. The sleep and ndash;wake rhythm is disrupted continuously or in repeating phases depending on lack of balance between internal and external cycles. This condition leads to functional impairments which cause insomnia, excessive sleepiness or both in people. Application of detailed sleep anamnesis and sleep diary with actigraphy record, if possible, will be sufficient for diagnosis. The treatment aims to align endogenous circadian rhythm with environmental conditions. The purpose of this article is to review pathology, clinical characteristics, diagnosis and treatment of circadian rhythm disorder.

Parasomnias: Diagnosis, Classification and Clinical Features

Parasomnias, as described in the recent second edition of the International Classification of Sleep Disorders, are “undesirable physical events or experiences” occurring during sleep transition, during arousal from sleep, or within the sleep period. These events encompass abnormal sleep related movements, behaviors, emotions, perceptions, dreaming, and autonomic nervous system functioning. Parasomnias are classified as: 1) disorders of arousal (from non-rapid eye movement, or NREM, sleep); 2) parasomnias usually associated with REM (rapid eye movement) sleep; and 3) other parasomnias. This sleep disorders in childhood are common, and often more frequent than in adults. Clinicians should be aware that many pediatric parasomnias have benign and self-limited nature. Most of the parasomnias may not persist into late childhood or adolescence. Parasomnias in adults often differ in type from childhood parasomnias and may portend significant psychiatric disturbances or neurodegenerative disorders. A reliable diagnosis can often be made from a detailed history from the patient and, if possible, the parents or bed partner. Detailed overnight investigations of parasomnias are usually not required. The non-REM parasomnias are more common in community although REM parasomnias are more likely to be seen in general neurological practice. Sleep related eating disorder, sleep related dissociative disorders and sleep related sexual behavior and sleep related violence are novel and rarely reported sleep disorders. REM sleep behavior disorder is common and should be sought in all neurodegenerative diseases. They are included among clinical disorders due to the resulting injuries, and adverse health and psychosocial effects, which may affect the bed partner as well as the patient. Finally, parasomnias are common disturbances of sleep that may significantly affect the patient’s quality of life and that of the bed partner. Therefore, appropriate diagnostic and therapeutic strategies are warranted

Sociodemographic Variables and Depression in Turkish Women From Polygamous Versus Monogamous Families

In this study, we aimed to determine the different sociodemographic variables of polygamous and monogamous wives, and the relationship between depression and polygamous marriage. Seventy-nine polygamous wives and 73 monogamous wives from Kahramanmaras, located in southern Turkey, were interviewed. After reviewing the data, we suggest that there is a statistically significant difference between polygamous wives and monogamous wives in terms of Beck Depression Inventory (BDI) scores. The results highlighted many implications for clinical practice and for future research. Additional research needs to be conducted in order to investigate the effects of polygamy on women's mental health

Impulsivity and Emotional Factors in Obesity: A Preliminary Study

WOS: 000302187200003Objective: The aim of this study was to investigate the relationship of obesity with impulsivity and emotional factors. Methods: Forty-eight obese participants included in the study were compared with 48 normal-weight controls. The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Eating Attitudes Test (EAT), Beck Depression Scale (BDS), and the Barrat Impulsiveness Scale-11 (BIS-11) were administered to all participants. Results: Forty-eight obese participants were split into two groups: with regard to presence of binge eating disorder - binge eating group (22 subjects - 19 females and 3 males) and non-binge eating group (26 subjects - 25 females and 1 males). No difference was detected between the groups in terms of impulsivity scores (p>0.05). Twenty-five of the 48 subjects with obesity were diagnosed with depressive disorder according to the DSM-IV criteria. Eight of the 48 control subjects had depressive disorder. Eating Attitudes Test and Beck Depression Scale scores were statistically significantly higher in the obese group than in the control group (p<0.05). We also compared the impulsivity scores between the depression and non-depression groups where impulsivity scores were found to be significantly higher in the depression group than in the non-depression group (p<0.05). Similarly, in the obese group, impulsivity scores of subjects with more elevated depression scores were significantly higher than those with lower depression scores (p<0.05). Conclusion: The foremost finding of this study was determination of a stronger relationship between obesity and emotional traits than the relationship between obesity and impulsivity traits. In the current study, we also observed high impulsivity scores in the depression group. This result was associated more with the relationship between depression and impulsivity than with the relationship between obesity and impulsivity. Further studies with larger samples are required.

Evaluation of Activity of Some 2,5-Disubstituted Benzoxazole Derivatives against Acetylcholinesterase, Butyrylcholinesterase and Tyrosinase: ADME Prediction, DFT and Comparative Molecular Docking Studies

In this study, p-tert-butyl at position 2 and acetamide bridged 4-substituted piperazine/piperidine at position 5 bearing benzoxazole derivatives were evaluated for their in vitro inhibitory activity against AChE, BChE and Tyrosinase, which are important targets in reducing the adverse effects of Alzheimer's disease. The most active 1 g inhibited the BChE at a concentration of 50 mu M by 54 +/- 0.75%. Molecular docking studies of the compounds against BChE (PDB: 4BDS) were performed with Schrodinger and AutoDock Vina and the results were compared. Schrodinger docking scores were found to be more consistent. Estimated ADME profiles and bioactivity scores of the compounds were calculated and found to be compatible with Lipinski and other limiting rules. Geometric optimization parameters, MEP analysis and HUMO and LUMO quantum parameters of the most active 1 g were calculated by using DFT/B3LYP theory and 6-311 G (d,p) base set and results was viewed

Biological evaluation and docking studies of some benzoxazole derivatives as inhibitors of acetylcholinesterase and butyrylcholinesterase

A series of 2,5-disubstituted-benzoxazole derivatives (1-13) were evaluated as possible inhibitors of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The results demonstrated that the compounds exhibited a broad spectrum of AChE and BChE inhibitory activity ranging between 6.80% and 90.21% except one compound which showed no activity against AChE at the specified molar concentration. Another derivative displayed a similar activity to that of reference drug (galanthamine) for inhibition of AChE and BChE. In addition, molecular docking of the compounds into active site of AChE was performed using recombinant human AChE (PDB ID: 4ey6) in order to understand ligand-protein interactions

Case Report External Hemorrhage from a Portacaval Anastomosis in a Patient with Liver Cirrhosis

Variceal bleeding is the major complication of portal hypertension in patients with liver cirrhosis. Hemorrhage mainly occurs in gastrointestinal lumen. Extraluminal hemorrhages are quite rare, such as intraperitoneal hemorrhages. We aimed to present a variceal bleeding case from the anastomosis on the anterior abdominal wall, as an extraordinary bleeding location, in a patient with portal hypertension in whom there were no esophageal and gastric varices
