ABSTRACT

BACKGROUND: In 2016, 44,965 people in the United States died by suicide. It is common to see people with suicidal ideation seek help or leave suicide notes on social media before attempting suicide. Many prefer to express their feelings with longer passages on forums such as Reddit and blogs. Because these expressive posts follow regular language patterns, potential suicide attempts can be prevented by detecting suicidal posts as they are written. OBJECTIVE: This study aims to build a classifier that differentiates suicidal and nonsuicidal forum posts via text mining methods applied on post titles and bodies. METHODS: A total of 508,398 Reddit posts longer than 100 characters and posted between 2008 and 2016 on SuicideWatch, Depression, Anxiety, and ShowerThoughts subreddits were downloaded from the publicly available Reddit dataset. Of these, 10,785 posts were randomly selected and 785 were manually annotated as suicidal or nonsuicidal. Features were extracted using term frequency-inverse document frequency, linguistic inquiry and word count, and sentiment analysis on post titles and bodies. Logistic regression, random forest, and support vector machine (SVM) classification algorithms were applied on resulting corpus and prediction performance is evaluated. RESULTS: The logistic regression and SVM classifiers correctly identified suicidality of posts with 80% to 92% accuracy and F1 score, respectively, depending on different data compositions closely followed by random forest, compared to baseline ZeroR algorithm achieving 50% accuracy and 66% F1 score. CONCLUSIONS: This study demonstrated that it is possible to detect people with suicidal ideation on online forums with high accuracy. The logistic regression classifier in this study can potentially be embedded on blogs and forums to make the decision to offer real-time online counseling in case a suicidal post is being written.

ABSTRACT

BACKGROUND: Numerous studies in youth and adults suggest strong association between substance use disorders and non-suicidal self-injury (NSSI) and suicidal behaviors. There is paucity of studies exploring the association of substance use with history of suicide attempts (HSA) and NSSI in children and adolescents in Turkey. OBJECTIVE: We aimed to examine the prevalence of NSSI and HSA and their relationship with substance use and family characteristics among youth seeking treatment for substance use in Turkey. METHOD: Participants were children and adolescents who were admitted to the Bakirkoy Trainee and Research Hospital for Psychiatric and Neurologic Disorders in Istanbul between January 2011 and December 2013. Two thousand five hundred eighteen participants were included. Questionnaires were applied to all patients. The association of NSSI and HSA with substance use, family characteristics, and subject characteristics were analyzed. RESULTS: The prevalence of NSSI and HSA behaviors among substance using youth in our sample were 52% and 21% respectively. Cannabis and cocaine use was found to be a significant risk factor for HSA, and polysubstance use was associated with both NSSI and HSA. Parental separation/divorce, parental mental disorders, alcohol and drug use, and crime were the risk factors for HSA. A positive history of physical and sexual abuse increased the risk of HAS, and a history of neglect increased the risk of NSSI. Conclusions/importance: We suggest that results showing relationship between substance use and associated social features with NSSI and HSA may contribute to elaborating effective and targeted preventive and intervention programs for these high-risk youth groups in Turkey.

ABSTRACT

BACKGROUND: The aim of this study was to evaluate dietary quality of adolescents by using the Healthy Eating Index (HEI) and to assess their eating attitudes by the EAT-26 Eating Attitude Test. METHODS: Eight schools; four primary schools and four secondary schools were randomly selected from the school list of official website of Istanbul Education National Directorate. Five hundred and ninety-eight students who met the inclusion criteria included in the study, 24 h dietary recalls were collected to calculate their HEI scores and eating attitudes were evaluated by EAT-26 Eating Attitude Test. Their weight, height and waist circumference were measured. RESULTS: According to HEI scores, only two (0.3%) of adolescents had high quality diet, 379 (63.4%) had diet quality that needed improvement and 217 (36.3%) had poor diet. Regarding Eating Attitude Test scores, 513 (85.8%) had normal attitudes regarding eating behaviors. CONCLUSION: Almost all of the participants need either development or major changes in their eating behaviors. Interventions aiming high quality diet among adolescents are strongly recommended.

ABSTRACT

Early recognition of congenital cardiac pathologies and their treatment by means of palliative or corrective surgery at birth or infancy has vital importance. Successful repair of congenital cardiac defects by surgical methods has gained importance especially during the last twenty years. As the scope of the surveillance increased so did the interest in the outcomes of these treatments when the patients had reached puberty and adulthood. The purpose of our research was to study the psychological framework of the adolescents who had experienced these surgeries by listening both the children and the parents talk about their feelings and experiences. Our data was accumulated through interviews with 17 adolescents and their families, using qualitative methods. The main theme at the end of the analysis was "to be strong and resistive". We reached the conclusion that this condition was not a pathological build up but an attitude of coping, as it did not cause loss of functionality. The defensive psychological mechanisms used by these adolescents consisted of repression, compensation and reaction formation. We believe that this information is important to understand the real meaning of the manners displayed when these adolescents and their families pursue their daily lives, communicate and make relationships with their environment and especially professionals in the health services.

ABSTRACT

BACKGROUND: An increased prevalence of behavioral problems has been described among children with asthma. OBJECTIVE: To investigate those associations between common behavioral problems and asthma, with an emphasis on the roles of medications used for asthma. METHOD: We studied 409 children who had been followed-up in pediatric allergy clinics and 157 age-matched healthy controls. A diagnostic and statistical manual disorder-referenced symptom inventory was used to assess "attention deficit-hyperactivity disorder" (ADHD), "attention deficit" (AD), "hyperactivity and impulsivity" (HI), and "oppositional defiant disorder" (ODD) behavioral problems. RESULTS: The study group consisted of 409 patients (male: 251, female: 158), with a mean age of 9.0 ± 2.67 years, and the control group consisted of 157 children (male: 75, female: 82), with a mean age of 9.0 ± 2.86 years. Prevalences of AD, hyperactivity, ADHD, and ODD were not significantly different between the study and control groups. Among those patients receiving leukotriene antagonist (LA) drugs adjunctive to inhaled corticosteroids (ICS), duration of treatment was correlated with total scores calculated for hyperactivity (P = .035, r = 0.432), AD (P = .044, r = 0.414), ADHD (P = .042, r = 0.418), and ODD (P = .032, r = 0.439). Among patients with asthma, children with ODD had a significantly longer duration of LA+ICS use (P = .024) compared with those with no ODD. Patients with hyperactivity had a longer duration of ICS+LA use compared with those with no hyperactivity (P = .009). Patients with asthma receiving LA+ICS treatment had a higher risk for oppositional behavior (4.282 times compared with the control group [P = .042, confidence interval (CI): 1.542-15.949]) and 8.3 times compared with patients with asthma not using any drug (P = .021, CI: 1.419-48.543). CONCLUSION: Rather than asthma itself, adjunctive use of ICS+LA therapy appears to be related with symptoms of common behavioral problems, including hyperactivity, AD, ADHD, and ODD and to increase the risk of ODD.

ABSTRACT

The modern age of psychosurgery can be said to have started with Moniz and Lima. Freeman and Watts subsequently revised and popularised the lobotomy procedure. Moniz shared the 1949 Nobel Prize for medicine or physiology for his discovery of the therapeutic value of leucotomy in certain psychoses, which accelerated the worldwide popularisation of lobotomy, particularly during the years from 1948 to 1953. In Turkey, psychosurgical interventions were first performed in the early 1950s, and were applied in almost 400 cases. These operations gradually ceased after the discovery and worldwide clinic applications of a modern antipsychotic drug named Chlorpromazine in 1950s, paralleling a similar trend in other countries. Our paper reviews the clinical, psychometric and histopathological results of psychosurgery performed in Turkey in the 1950s.
