The relationship between Type D personality and impulsivity in university students
Authors: YILDIZ Mesut
Published: June 2023

Abstract

Aim: Type D personality is defined as a type in which negative affecttivity (NA) and social inhibition (SI) are prominent. Type D personality is associated with psychiatric symptoms. The aim of the present study is to investigate the relationship between Type D personality and impulsivity in a non-clinical population.

Materials and Methods: In total, 462 undergraduate health Professional students were recruited to the study. Subjects were evaluated using Beck Anxiety Inventory (BAI), Beck Depresssion Inventory (BDI), Barratt Impulsivity Scale-11 (BIS-11) and Type D Personality Scale (DS-14).

Results: The frequency of type D personality was 39.6%. The BAI, BDI and BSI scores were higher in participants with Type D personality compared to the group without Type D personality. Correlation analysis demonstrated that Type D personality was posivitely correlated with the severity of depression and anxiety. Impulsivity scores measured by the BSI was posivitely correlated with Type D personality, depression and anxiety scores. Regression analysis demonstrated that impulsivity was predicted by male sex and depression scores.

Conclusion: Type D personality was correlated with the severity of depression and anxiety. Depression scores and male sex predicted impulsivity.

Aim: The aim of this study was to investigate the efficacy of a home-based breathing exercise program on dyspnea, quality of life, depression and sleeping disorders in patients with COVID-19 after discharge from the hospital.

Methods: The study was completed with a total of 60 participants. The intervention group (n=39) received a homed-based exercise program including controlled breathing techniques and low-intensity upper and lower extremity exercises. The control group (n=21) did not receive any intervention.

The patients were evaluated with the Modified Borg Scale (MBS), Nottingham Health Profile (NHP), Insomnia Severity Index (ISI) and Beck Depression Inventory (BDI) before and at the end of the intervention.

Results: After treatment, the MBS scores significantly decreased in both the intervention and control groups compared with the baseline values(p

Published: June 2023

Abstract

Aim: Colorectal cancer is a serious disease that can result in death. The fact that cancer markers and early diagnosis increase the effectiveness of treatment reveals the need for multidimensional research on this subject. TNM classification of colorectal cancer is shows the prognosis. In our study, the relationship between preoperative CEA and CA 19-9 values and histopathology of tumor and preoperative predictive value of tumor markers in colorectal cancer patients were investigated.

Materials and Methods: 153 patients diagnosed with colorectal cancer were included in the study. The histopathological data in the resection materials of the patients who were operated by General Surgery Department were collected from the pathology reports. Clinical data were collected by retrospective scanning of patient files.

Results: The mean age of the patients was 64 (± 11.39) years. 51.6% were male and 48.4% were female. CEA was found to be positive in 35.3% of the patients, while this rate was 20.9% for CA 19-9. In our study, CEA and CA 19-9 positivity were significantly correlated with TNM stage of tumor, depth of invasion, lymphovascular invasion, perineural invasion, nodal involvement and metastasis. In addition, the mean age of CA 19-9 positive cases was significantly higher than the negative ones. The mean tumor size of CEA positive cases was significantly higher than the negative ones.

Conclusion: CEA and CA19-9 are valuable both in demonstrating advanced stage tumors and in detecting malignancy in tumors detected in advanced ages. Since survival decreases as the stage progresses, positive CEA and CA19-9 values are both associated with worse prognosis.
Bibliometric Analysis On Laparoscopic Hysterectomy Technique in Obstetrics And Gynecology Research Area
Authors: ALTINTAŞOĞLU Fatmahorasan
Published: June 2023

Abstract Background/Aim: This bibliometric study aimed to analyze published articles in the field of laparoscopic hysterectomy in order to identify their characteristics and trends. Method: The analysis covered all studies that had been published on laparoscopic hysterectomy (LH) that were published between 1992 and December 31, 2021. Bibliometric data was gathered from the Web of Science database, and VOSviewer software was used to construct bibliometric diagrams. Result: A total of 993 articles according to the search criteria. 12.79% of the articles were published as open access and 96.375% were in English. Since 2010, 57% of articles have been published. These articles had an h-index of 70, a total of 23538 citations, and an average of 23.7 citations per article. Although the number of publications about LH changes from year to year, it peaked in 2015 (the number of publications was 59) and it had the highest citation numbers (n = 1800) in 2021. 3448 authors contributed to the publication of scholarly works on LH. Prof. Fabio Ghezzi from the University of Insubria (Italy) was the most published author on LH with 25 articles. Prof. Fabio Ghezzi’s articles on LH were cited 735 times (29.4 per article). The majority of the articles were published by affiliates in Italy and the United States. Conclusion: This study represents the first bibliometric analysis of laparoscopic hysterectomy. Laparoscopic hysterectomy research has advanced but slowed in recent years. Developing nations should consider increasing research funding to produce substantial research that can serve as the foundation for locally applicable, evidence-based laparoscopic hysterectomy interventions.
