The synthesis and in vitro characterization of the mucoadhesion and swelling of poly(acrylic acid) hydrogels

Depression is a significant problem in epilepsy. Suicides occur in epileptic patients five times more often than in general population. Material included 34 epileptics with 76 suicidal attempts and 24 patients with no history of suicide. Psychical state was studied with Beck Depression Inventory and Hamilton Depression Rating Scale. In the group with suicidal attempts 65% of patients had depression (54.5% of them had major depression) and in group without suicide attempts depression was noted in 54% (23% with major depression). Patients with depression were divided into two groups: group I with suicidal attempts and group II without history of suicide. In group I more patients were alcohol abusers (50% vs 31%), more were treated because of epilepsy longer than 10 years (59% vs 46%) and more had tonic-clonic seizures (82% vs 46%). In group I, 54% of patients were on polytherapy (more than half of them with fenobarbital). In group II, 31% of epileptics were on polytherapy (no one with fenobarbital). Major depression was significantly more frequent in epileptics with suicidal attempts. The severity of depression may influence the risk of suicide. Major depression may be associated with late age of onset of epilepsy, longer treatment duration, tonic-clonic seizures, polytherapy (mainly with fenobarbital) and alcohol abuse.     

Suicide attempters within a delinquent population.

Contrasted 30 13–15 yr old delinquents who had attempted suicide with 120 delinquent controls. Multiple regression analyses showed that suicidal ideation, depression, gender, a tendency to act out, conflict with parents, childhood hyperactivity, and the interactions of gender with depression and with acting out accounted for 49% of the variance in suicide attempts. Females were found to attempt suicide 2? times as often as males. Females were also more likely to attempt suicide when depressed than were similarly depressed males. Male and female delinquents who engaged in a high level of acting out were equally likely to attempt suicide, but females who did not act out were more likely to attempt suicide than males who did not act out. Similarities between these adolescent attempters and adult suicide attempters described in the literature are discussed. (34 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attempted suicide in Oxford University students, 1976-1990

During the 14 years between the beginning of academic year 1976-7 and the end of academic year 1989-90, 216 Oxford University students (119 females and 97 males) were referred to the general hospital in Oxford because of suicide attempts (254 in all). The rate of attempted suicide during university term-time (106/100,000) was lower than in other young people of similar age in Oxford City (164/100,000). The difference was particularly marked in females (178/100,000 v. 269/100,000). The lower rate in the students may in part reflect their generally higher socio-economic status. Very few of the attempts by the students appeared to be failed suicides. The most frequent problems faced by the students at the time of their attempts were interpersonal, especially difficulties regarding partners, followed by academic problems. The latter were usually problems with ongoing course work rather than with the Finals examinations. Approximately a quarter of the students had psychiatric problems, with personality disorders and depression being most common. At least 30% had a history of previous attempts. Suggestions are made concerning measures for improving the management and prevention of attempted suicide by students.     

Are body dissatisfaction, eating disturbance, and body mass index predictors of suicidal behavior in adolescents? A longitudinal study.

Disordered eating, body dissatisfaction, and obesity have been associated cross sectionally with suicidal behavior in adolescents. To determine the extent to which these variables predicted suicidal ideation and attempts, the authors examined these relationships in a longitudinal design. The study population included 2,516 older adolescents and young adults who completed surveys for Project EAT-II (Time 2), a 5-year follow-up study of adolescents who had taken part in Project EAT (Time 1). Odds ratios for suicidal behaviors at Time 2 were estimated with multiple logistic regression. Predictor variables included Time 1 extreme and unhealthy weight control behaviors (EWCB and UWCB), body dissatisfaction, and body mass index percentile. Suicidal ideation was reported by 15.2% of young men and 21.6% of young women, and suicide attempts were reported by 3.5% of young men and 8.7% of young women. For young women, suicidal ideation at Time 2 was predicted by Time 1 EWCB. The odds ratio for suicide attempts was similarly elevated in young women who had reported EWCB at Time 1. These odds ratios for both suicidal ideation and suicide attempts remained elevated even after controlling for Time 2 depressive symptoms. In young men, EWCB was not associated with suicidal ideation or suicide attempts 5 years later. Body mass index and body dissatisfaction did not predict suicidal ideation or suicide attempts in young men or young women. These results emphasize the importance of EWCB.

Psychiatric diagnoses as contemporaneous risk factors for suicide attempts among adolescents and young adults: Developmental changes.

The purpose of this prospective, naturalistic study was to examine the relationships between suicide attempts and contemporaneous psychiatric disorders, and developmental changes in these relationships from adolescence to young adulthood. The sample consisted of 180 adolescents, 12–19 years of age at hospitalization, repeatedly assessed for up to 13 years (n = 1,825 assessments). Semistructured psychiatric diagnostic instruments were administered at repeated assessments to assess psychiatric disorders and suicide attempts. After controlling for demographic variables and prehospitalization suicide attempts, most contemporaneous psychiatric disorders (major depressive disorder [MDD], dysthymic disorder, generalized anxiety disorder [GAD], panic disorder, attention-deficit/hyperactivity disorder [AD/HD], conduct disorder, and substance use disorder [SUD]) were related to increased risk of attempts. The relationship between suicide attempts and MDD, GAD, AD/HD, and SUD strengthened as participants got older. MDD, dysthymic disorder, GAD, and panic disorder were more commonly associated with repeat than 1st-time suicide attempts. In sum, most major psychiatric disorders are associated with increased risk for suicide attempts, but the strength of the relationships between these disorders and attempts changes over the course of development.

Suicide attempts in a cohort of drug abusers: a 5-year follow-up study

A group of 125 drug abusers admitted consecutively for detoxification and short-term rehabilitation were followed up 5 years after discharge. They were asked about possible suicide attempts in a semi-structured face-to-face interview. Nearly half of the group (45%) reported having attempted suicide at some point in their life. The most common reasons given were the loss of a person whom they loved, and feelings of loneliness. Only three respondents reported using their drug of choice in the attempt(s). The suicide attempters were more often found to have been in child psychiatric treatment earlier, and to have experienced loss of significant others in childhood, than those who did not report attempting suicide. At follow-up the suicide attempters indicated that they experienced more depressive moods and more severe psychological problems than those who had never made a suicide attempt. The importance of assessing the risk of suicide attempts among drug addicts in order to be able to take measures to prevent future suicidal behaviour is emphasized.     

Computerized prompts for cancer screening in a community health center

One hundred eleven (58%) of 191 adolescent inpatients previously admitted to the emergency wards at the Child and Adolescent Psychiatric Clinics in the cities of Uppsala and G?teborg participated in a 2-4 year follow-up evaluation. The prevalence, incidence, and stability of depressive symptoms, suicidal ideation, and suicide attempts among the adolescents, and predictors of follow-up functioning were examined. Although a majority of the patients substantially reduced their depressive symptoms over the 2-4 year period, a smaller group (13%), mainly girls (94%), continued reporting high symptom levels at follow-up, and one out of five adolescents had moderate-severe levels of suicidal ideation. The accumulated frequency of suicide attempts among the patients shortly prior to hospitalization and during the follow-up was 59% including two patients who committed suicide. Significant predictors of depressive symptom severity at follow-up were depressive symptom scores and V-diagnoses at inpatient assessment. Previous suicide attempts before hospitalization, high levels of self-reported depressive symptoms and nonintact family status at inpatient assessment predicted suicide attempts during the follow-up period. The high prevalence of attempted and completed suicide in this clinical group underscores the importance of developing effective treatments for suicidal adolescents.     

Suicide and other causes of death in patients admitted for attempted suicide. 10-year follow-up

The purpose of this study has been to describe the course over ten years and prognosis for a cohort of patients who had been admitted to a psychiatric department following a suicide attempt. The cohort consisted of 207 patients who had been admitted in the period 1.10.1980-20.4.1981 to a department of psychiatry following a suicide attempt. At the index attempt 99 patients were randomly selected and interviewed. Information on the remainder was obtained from psychiatric case histories, casualty records and discharge reports. Ten years after the index attempt information concerning death, date and cause was collected. Of the 207 patients involved, 52 (25.1%) were dead. Twenty-five (12.1%) had committed suicide, the remainder had died of natural, accidental or unknown causes. Relative to the general population the death rate from suicide and other causes was extremely high. Predictors of suicidal outcome were substance abuse and dangerous index attempt. At least one of these two predictors was present for 72% of those who committed suicide and for 43% of those who did not commit suicide. Aging and previous suicide attempts were the only significant predictors of other causes of death.     

Attempted suicide in Europe: rates, trends and sociodemographic characteristics of suicide attempters during the period 1989-1992. Results of the WHO/EURO Multicentre Study on Parasuicide

The World Health Organization/EURO Multicentre Project on Parasuicide is part of the action to implement target 12 of the WHO programme, "Health for All by the Year 2000', for the European region. Sixteen centres in 13 European countries are participating in the monitoring aspect of the project, in which trends in the epidemiology of suicide attempts are assessed. The highest average male age-standardized rate of suicide attempts was found for Helsinki, Finland (314/100,000), and the lowest rate (45/100,000) was for Guipuzcoa, Spain, representing a sevenfold difference. The highest average female age-standardized rate was found for Cergy-Pontoise, France (462/100,000), and the lowest (69/100,000) again for Guipuzcoa, Spain. With only one exception (Helsinki), the person-based suicide attempt rates were higher among women than among men. In the majority of centres, the highest person-based rates were found in the younger age groups. The rates among people aged 55 years or over were generally the lowest. For the majority of the centres, the rates for individuals aged 15 years or over decreased between 1989 and 1992. The methods used were primarily "soft' (poisoning) or cutting. More than 50% of the suicide attempters made more than one attempt, and nearly 20% of the second attempts were made within 12 months after the first attempt. Compared with the general population, suicide attempters more often belong to the social categories associated with social destabilization and poverty.     

Suicide attempts among the elderly

The purpose of the study is to describe the life stories leading to the suicide attempts. In-depth interviews with nine persons who had attempted suicide (six females and three males, mean age 73 years) were analysed using a qualitative method. Five categories describe the main interview topics: "I had to leave home to survive." (childhood, youth), "You have to bear it." (adult life), "I will manage, I always have." (present life), "You have to give in order to get. If you have nothing to offer, then life is not worth living." (expectations for future life), "I want to decide my own life." (reflections concerning the suicide attempt). The life stories have a common theme; the patients grew up under very difficult conditions and had little emotional support. Their basic trust was poorly developed and their self-esteem was dependent on their capability to work and to give. Without this capability they felt worthless, and life was unbearable. Attempted suicide was the consequence.     

Prediction of local recurrence of ductal carcinoma in situ of the breast using five histological classifications: a comparative study with long follow-up

OBJECTIVE: To identify the independent and differential diagnostic and symptom correlates of suicidal ideation and suicide attempts and determine whether there are gender- and age-specific diagnostic profiles. METHOD: The relationships between suicidal ideation, suicide attempts, and psychiatric disorders were examined among 1,285 randomly selected children and adolescents, aged 9 to 17 years, of whom 42 had attempted suicide and 67 had expressed suicidal ideation only. Youths and their parents were interviewed as part of the Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study, using the Diagnostic Interview Schedule for Children Version 2.3 (DISC-2.3). RESULTS: Logistic regression analyses indicated that mood, anxiety, and substance abuse/dependence disorders independently increased the risk of suicide attempts, after controlling for sociodemographic characteristics. There was no significant independent contribution of disruptive disorders to suicide attempts, although its association with suicidal ideation was significant. Substance abuse/dependence independently differentiated suicide attempters from ideators. Noncriterion symptoms that remained significant predictors of suicide risk, after adjusting for psychiatric disorder, included panic attacks and aggressiveness. Perfectionism did not significantly increase suicide risk after adjusting for psychiatric disorder. The association of specific disorders and noncriterion symptoms with suicidality varied as a function of gender and age. CONCLUSION: A monolithic diagnostic risk profile for suicidality, ignoring gender- and age-specific risks, is inadequate. The contribution of substance abuse/dependence in the escalation from suicidal thoughts to suicide attempts is underscored.     

Psychiatric history and symptom differences in black and white depressed patients.

Compared 159 black psychiatric patients with 555 white patients on a battery of social, personality, and psychiatric history variables, as well as presenting symptoms. In making these comparisons, race differences in age, social class status, and sex were controlled. Both black and white depressed patients were remarkably similar on presenting symptoms, especially the core symptoms of depression, when the groups were equated or controlled for age and social class differences. However, some differences did emerge on a number of hostility variables. There was a greater tendency toward negativism and the introjection of anger in blacks than in whites. In addition, depressed black males indicated that they were more likely than their white counterparts to strike back, either verbally or physically, when they felt their rights were being violated. There was also a very high incidence of suicide threats or attempts among the black males. (17 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Correlates of suicidal behavior in a juvenile detention population

The present study identifies the correlates of current suicidal ideation and past suicide attempt among 555 adolescents in a county juvenile detention center. Suicidal behavior in delinquent boys was generally associated with depression and decreased social connection, whereas suicidal behavior in delinquent girls was associated with impulsivity and instability. Current ideation was most significantly associated with current depression. In multivariate analyses, past attempts were associated with suicidal ideation and ineffective coping for males, with major life events and impulsivity for females, and with not residing with at least one biological parent prior to detention for both males and females.     

Predictors of suicide attempts: State and trait components.

The authors examined the state and trait components of 3 predictors of suicide attempts (depression, hopelessness, and anxiety), and their relationship to suicidal behavior. Self-report questionnaire and interview data from 180 adolescents enrolled in a prospective naturalistic study were analyzed. Between 23% and 30% of the variance in the predictors was attributable to subjects' trait levels of these variables; the trait, as well as the state, components of the predictor variables were interrelated; and trait levels of these variables were consistently related to suicide attempts. To reduce long-term risk of suicide attempts, clinicians should focus not only on reducing short-term distress but also on reducing individuals' more enduring patterns (trait levels) of negative affectivity.

Recent Life Events Preceding Suicide Attempts in a Personality Disorder Sample: Findings From the Collaborative Longitudinal Personality Disorders Study.

Few studies have examined the relationship between life events, suicide attempts, and personality disorders (PDs), in spite of the strong associations between PDs and suicidal behavior, and the poor coping strategies often exhibited by these individuals. The authors examined whether participants with PDs who attempted suicide during the first 3 years of a prospective, longitudinal study were more likely to experience specific life events in the month during and preceding the suicide attempt. Of 489 participants with PDs, 61 attempted suicide during the 3-year, follow-up interval. Results indicated that negative life events, particularly those pertaining to love-marriage or crime-legal matters, were significant predictors of suicide attempts, even after controlling for baseline diagnoses of borderline PD, major depressive disorders, substance use disorders, and a history of childhood sexual abuse. Therefore, certain types of negative life events are unique risk factors for imminent suicide attempts among individuals with PDs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Toward a clinical model of suicidal behavior in psychiatric patients

OBJECTIVE: Risk factors for suicide attempts have rarely been studied comprehensively in more than one psychiatric disorder, preventing estimation of the relative importance and the generalizability of different putative risk factors across psychiatric diagnoses. The authors conducted a study of suicide attempts in patients with mood disorders, psychoses, and other diagnoses. Their goal was to determine the generalizability and relative importance of risk factors for suicidal acts across diagnostic boundaries and to develop a hypothetical, explanatory, and predictive model of suicidal behavior that can subsequently be tested in a prospective study. METHOD: Following admission to a university psychiatric hospital, 347 consecutive patients who were 14-72 years old (51% were male and 68% were Caucasian) were recruited for study. Structured clinical interviews generated axis I and axis II diagnoses. Lifetime suicidal acts, traits of aggression and impulsivity, objective and subjective severity of acute psychopathology, developmental and family history, and past substance abuse or alcoholism were assessed. RESULTS: Objective severity of current depression or psychosis did not distinguish the 184 patients who had attempted suicide from those who had never attempted suicide. However, higher scores on subjective depression, higher scores on suicidal ideation, and fewer reasons for living were reported by suicide attempters. Rates of lifetime aggression and impulsivity were also greater in attempters. Comorbid borderline personality disorder, smoking, past substance use disorder or alcoholism, family history of suicidal acts, head injury, and childhood abuse history were more frequent in suicide attempters. CONCLUSIONS: The authors propose a stress-diathesis model in which the risk for suicidal acts is determined not merely by a psychiatric illness (the stressor) but also by a diathesis. This diathesis may be reflected in tendencies to experience more suicidal ideation and to be more impulsive and, therefore, more likely to act on suicidal feelings. Prospective studies are proposed to test this model.     

Familism, mother-daughter mutuality, and suicide attempts of adolescent Latinas.

National surveys in the U.S. reveal that Latina adolescents have higher rates of suicide attempts than females of other ethnic and racial groups. Past reports indicate that the suicide attempts among Latinas are lodged within family contexts in which sociocultural and individual experiences influence parental and adolescent behaviors. To better understand the parent-adolescent relations that explain the Latina suicidal phenomenon, we examined how the high value on family unity and support, as reflected by familism, and its effects on mother-daughter mutuality (i.e., reciprocal empathy and engagement) were evident in a group of adolescent Latinas with suicide attempts and a group of adolescent Latinas without suicide attempts. Drawing from data on 169 mother-daughter dyads recruited from Latino communities in a Northeastern metropolis and who self-identified as being of Latino origin or heritage, we considered how differences in familism between mothers and daughters influenced their sense of mutuality, the adolescents' internalizing and externalizing behaviors, and suicide attempts. Results show that gaps in familism (mothers scoring higher than their daughters on the scale) predicted less mother-daughter mutuality and more externalizing behaviors in the adolescents. Also, mother-daughter mutuality was negatively related to internalizing and externalizing behaviors which, in turn, predicted suicide attempts. Findings point to further research on family interactions that raise the risk for suicidality in Latino youth, particularly to including fathers and siblings in study designs. Clinical implications point to enhancing family and dyadic communication skills focusing mutuality while observing the cultural value of familism.

What is the mechanism by which suicide attempts predispose to later suicide attempts? A mathematical model.

A state dependence model of serial behavior suggests that each occurrence increases the subsequent likelihood of that behavior being repeated. A heterogeneity model, by contrast, suggests that the likelihood of a behavior occurring is predetermined and uninfluenced by intervening occurrences. We have applied the random-effects probit model of R. D. Gibbons and R. D. Bock (see record 1987-20831-001) to examine the fit of the state dependence and heterogeneity models to longitudinal data on suicide attempts by 928 patients with affective disorder. Heterogeneity but not state dependence was required to model these data. The findings suggest that when considering patients with moderate to severe major affective disorder, the clinician should not interpret the absence of any recent suicide attempts to mean that the patient is at relatively low risk for attempting suicide in the future. An implication of the heterogeneity model is that suicide attempts made many years ago may have equal value to recent attempts when estimating an individual's "predisposition" to nonlethal attempts in the future.

Diagnostic utility of video EEG monitoring in paroxysmal events

A total of 89 suicide attempters were diagnosed according to the DSM-III-R, and categorized according to suicide method as 'violent' and 'non-violent' attempters, and also as those who had made previous suicide attempts ('repeaters') and those who had not ('non-repeaters'). All of the subjects completed the MNT questionnaire. Our hypothesis was that the temperament patterns would reflect specific clinical characteristics, such as psychiatric diagnoses and type of suicidal behaviour. The 'validity' (ranging from fatiguableness to a high level of psychic energy) showed a bimodal distribution, suggesting the existence of two subgroups. The subjects with adjustment disorders displayed a significantly higher mean validity than the other patients. The lowest validity scores were found in subjects with bipolar depression. Men showed significantly higher 'stability' (reflecting emotional distance from others) than women. Subjects with major depression and those who were 'violent' suicide attempters showed somewhat higher 'solidity' (unchangeability, non-impulsiveness) compared with the other groups. Female 'non-repeaters' displayed significantly lower solidity than males or other females. In general, no clear temperament patterns were detected in patients categorized according to type of suicidal behaviour. In contrast to the findings of studies of normal populations, the intercorrelations between the dimensions were considerable, especially among the men. This prompted us to perform a cluster analysis procedure in which the subjects were allocated to five clusters according to the MNT dimensions. No distinct clinical characteristics appeared in these clusters, except in the cluster with the highest validity and the lowest stability, as 54% (P = 0.014) of the patients in this cluster had an adjustment disorder diagnosis. These temperament results reflect the clinical heterogeneity of patients who attempt suicide.     

The serious suicide attempt. Five-year follow-up study of 886 patients

A five-year follow-up study was undertaken of a previously reported 1968 cohort of 886 people who had attempted suicide. The working hypothesis that those who had seriously attempted suicide (21%) would have a higher suicide rate on long-term follow-up was confirmed. During the five-year follow-up period, a total of 34 suicides were found, which represented 3.84% of the total number at risk. Of those who had seriously attempted suicide, 12 (6.45%) of 186 succeeded later; of the other (nonserious or less serious) attempters, 22 (3.1%) of 700 succeeded. The serious-attempter suicide rate was 2.1 times that of the others, and this difference was statistically significant (P less than .05). In addition, patients who made attempts that were judged serious on medical but not on psychiatric grounds were found to have a suicide rate significantly higher (P less than .05) than patients who had made suicide attempts that were not a serious medical threat.
