Comparison of autogenous and reactive type obsessive-compulsive disorders in terms of clinical characteristics: A meta-analysis study.

Obsessive-compulsive disorder (OCD) has been divided into two subgroups autogenous and reactive types, based on obsessive symptoms. To our knowledge, no meta-analysis study compares sociodemographic and clinical characteristics. Investigation of the differences between the two groups in terms of these basic characteristics may provide information about the accuracy of this classification. This is the first meta-analysis to examine gender, age at onset and some clinical differences between patients with autogenous and reactive OCD. Electronic bibliographic databases of Scopus and PubMed were searched up to March 2024. Random effect models were conducted for this meta-analysis. The analysis was carried out using the standardized mean difference as the outcome measure. Publication bias was evaluated using the Begg and Eggers funnel plot, and fail-safe N calculation using the Rosenthal approach. The current meta-analysis summarizes the data from primary studies comparing the gender rates, age at onset of OCD, severity of obsessive-compulsive symptoms, and severity of depression and anxiety symptoms between autogenous and reactive types of OCD. The results of this study showed that the rate of male gender was higher in the autogenous type OCD. In addition, increased severity of anxiety, and depression were associated with autogenous type OCD. There was no significant difference between groups regarding the severity of obsessive-compulsive symptoms. Age of OCD onset findings were insignificant, but excluding an outlier study suggested earlier onset in autogenous type OCD. These results support the distinction between autogenous and reactive type OCD.

Turkish Adaptation, Validity and Reliability Study of the Bush Francis Catatonia Rating and KANNER Scales. / Bush Francis Katatoni Degerlendirme ve KANNER Katatoni Ölçeklerinin Türkçe Uyarlama, Geçerlik ve Güvenirlik Çalismasi.

OBJECTIVE: Catatonia is a common syndrome which can be lifethreatening due to its complications. The aims of the study were to translate the Bush Francis Catatonia Rating Scale (BFCRS) and the KANNER Scale into Turkish, conduct the validity and reliability analyses and to compare the two scales. METHOD: During the study period extending over 20 consecutive months, the Turkish versions of the scales were administered to 84 patients who were hospitalized in the psychiatry ward or who were admitted to the hospitalization list. The clinical and sociodemographic characteristics of all patients were evaluated. The scales were administered to the patients by two raters, one of whom was permanently involved. RESULTS: Convergent and criterion validities revealed a high correlation between the screening instruments of both scales and between the BFCRS total score and 2nd and 3rd part scores of the KANNER Scale. BFCRS total score of ≥6, KANNER Scale 2nd part score of ≥15, or 3rd part score of ≥1 can be used with high accuracy in diagnosing catatonia according to DSM-5. Internal consistency for both scales was found to be high (Cronbach's alpha 0.902 for BFCRS and 0.9, 0.891, 0.806 for KANNER Scale subsections). Inter-rater reliability was also high for most of the scale items (mean Kappa coefficient: 0.885 for BFCRS and 0.904 for KANNER Scale). CONCLUSION: In conclusion, the Turkish adaptations of both scales were found to be valid and reliable, showing strong psychometric properties. This study is the first validity and reliability study for the KANNER Scale.

Relationship Between the Needs of Turkish Relatives of Patients Admitted to an Intensive Care Unit and Their Coping Styles.

Admission to an intensive care unit is a traumatic event for many patients' relatives. Also, the relatives may be subject to many requirements to during this process. Therefore, it is very important to determine their requirements and coping styles. This study used a descriptive, relational design. The sample of the research consisted of 247 relatives of patients staying in six intensive care units. It was found that, 65.2% of the patients' relatives were women, and their mean age was 37.25 ± 12.7 years. What they mostly needed was support, proximity, information, assurance and comfort. In that order; among the coping styles it was found that they usually used the following approaches: self-confident approach, an problem-focused coping method; was found to be used by relatives most frequently, followed by helpless approach, an emotion-focused coping style. Requirements: Assurance, information, support and comfort sub-dimension scores and problem-focused coping style; self-confident approach and social support search approach sub-dimension scores between statistically positive, significant relationship was found. Information, proximity, support and comfort sub-dimension scores and emotion-focused coping style; helpless approach and submissive sub-dimension scores between statistically positive, significant relationship was found (p<0.05). It was found that patients' relatives used the helpless approach and submissive approach to cope with stres: during this process their information needs increased and upon fulfillment of requirements, they started using self-confident approach and the social support approach, which are problem-focused coping styles.

The effects of prolonged CO2 insufflation on kidney function in a rat pneumoperitoneum model.

INTRODUCTION: Pneumoperitoneum (PP) is known to cause ischemia in kidneys and other intra-abdominal organs because of decreased splanchnic blood flow. AIM: We aimed to determine the degree of renal injury that occurs due to a PP and prolonged PP. We measured renal injury biomarkers and made a histopathological evaluation to estimate the degree of injury and assessed the correlation of biomarkers with histopathological findings. MATERIAL AND METHODS: Twenty-one female Sprague Dawley rats were separated randomly into three groups. Group 1 was the control group and was given anesthesia for 3 h. In group 2, a PP was administered under anesthesia for 1 h. A pneumoperitoneum was administered under anesthesia to animals in group 3 for 3 h. RESULTS: Pathological analysis showed a significant statistical difference between the 3 groups. In particular, neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C (Cys C) levels at the 24th h and preoperative mean urea levels showed a significant difference between the groups. The 24th-hour NGAL level in group 3 was significantly higher than that of group 1. The preoperative Cys C level was higher in group 1 than in either group 2 or 3. Cys C was decreased significantly in group 1 and increased significantly in both groups 2 and 3. CONCLUSIONS: The increase in NGAL and Cys C levels directly correlated with the duration of PP and intra-abdominal pressure, and they are therefore good biomarkers in diagnosing acute renal injury in the early phase. Serum creatinine level is not a good biomarker in the early phase of renal injury.

Copper(II)-rubeanic acid coprecipitation system for separation-preconcentration of trace metal ions in environmental samples for their flame atomic absorption spectrometric determinations.

A simple and facile preconcentration procedure based on the coprecipitation of trace heavy metal ions with copper(II)-rubeanic acid complex has been developed. The analytical parameters including pH, amounts of rubeanic acid, sample volume, etc. was investigated for the quantitative recoveries of Pb(II), Fe(III), Cd(II), Au(III), Pd(II) and Ni(II). No interferic effects were observed from the concomitant ions. The detection limits for analyte ions by 3 sigma were in the range of 0.14 microg/l for iron-3.4 microg/l for lead. The proposed coprecipitation method was successfully applied to water samples from Palas Lake-Kayseri, soil and sediment samples from Kayseri and Yozgat-Turkey.
