An age-period-cohort study of completed suicides in Greece: Patterns and implications for suicide prevention

Suicide is a dynamic phenomenon. Psychiatric medication intake, illicit drug and alcohol use or the preference for particular suicide methods shift continuously over time. To capture such variations -and their potential implications for suicide prevention-, we researched the forensic records of suicide cases for the period 1992-2016 at a large department of forensic medicine and conducted age-period-cohort (APC) analyses of our sample (1162 suicides, 77.45% males, 22.25% females). We primarily investigated socio-demographic and toxicological parameters. Benzodiazepine, alcohol and illicit drug use increased considerably towards the younger cohorts. The segment of individuals of foreign nationality raised significantly too; likewise, the proportion of prison suicides. Hanging appears increasingly preferred by the younger APCs (the opposite is true for jumping). Hanging seems more popular among males, prisoners, and those under the influence of illicit drugs; jumping by females and those less likely to have consumed alcohol or illicit drugs. Given that the method of a prior attempt, if a highly lethal one, usually gets repeated in the completed suicide, a history of an attempt by hanging should never be underestimated. The mental health needs of immigrants and prisoners look inadequately addressed. Young-middle aged immigrant prisoners appear a group at high suicide risk.

Forensic data on adolescents who died by suicide in Greece

Introduction

Suicide is the second most common cause of adolescent mortality worldwide.

Objectives

To study the characteristics of a sample of adolescents (<18years of age) who died by suicide in Greece.

Methods

We investigated all suicides that took place within the area of the Piraeus Department of Forensic Medicine (population covered ~700,000) for the period 1992-2016, based on the victims’ forensic records.

Results

During the 25-year period, 16 adolescents (and 1162 adults) died by suicide. They were mostly males (11/68.75%) and of Greek Nationality (14/87.5%). The mean age was 15.56 years (range: 12-17, standard deviation: 1.46). Two (12.5%) were under psychiatric medication (an antipsychotic and an antidepressant, respectively); none was receiving a benzodiazepine or a mood-stabilizing antiepileptic. None had used amphetamine, cannabis, cocaine or heroin. Two (12.5%) -one girl one boy- had consumed alcohol. The suicides took place primarily at home (12/75%), followed by outdoors (3/18.75%); one (6.25%) took place in a correctional facility. Hanging was the most prevalent method (6/37.5), followed by jumping (5/31.25%), shooting by a firearm (2/12.5%), drowning (1/6.25%), medication overdose (1/6.25% -amitriptyline poisoning) and a case of suffocating death (1/6.25%). Most suicides happened in September (5/31.25%) and April (3/18.75%). No significant differences were noted with the adult sample.

Conclusions

The methods chosen by the adolescents who died by suicide in our sample differ strikingly from those of usual suicide attempts at that age (medication overdose/self-cutting). The periods when the suicides took place may imply a role for school stress. Our study was retrospective and focused primarily on a large urban area.

What does static electricity has to do with schizophrenia?

Introduction

The suspiciousness of a paranoid patient could reach extremes.

Objectives

To present the lessons learned after an interview with a similar patient.

Methods

Case report.

Results

Fifty-two year old woman suffering from paranoid schizophrenia (F20.0). Symptoms almost identical to her previous (two) hospitalizations: delusions of thought reading and of being surveilled by electronic equipment in her house/neighborhood. This time, though, she was additionally convinced of being the object of medical experiments and of being electronically surveilled even within the ward. Treatment: risperidone 12mg/day, lorazepam 3.75mg/day, biperiden 2mg/day. Three weeks after admission, the author noted a slight tremor in her hands (most certainly of extrapyramidal origin). I asked her to place both hands in front of her, fingers wide open, to assess it better. The patient followed with the fingers attached, though. Consequently, I approached my hands to hers -to show how it should be done correctly-, touching them lightly. Then, a spark was generated between our hands. Evidently, it was an electrostatic discharge (I was wearing a wool sweater that day; static electricity could easily accumulate on wool). She became outraged: “what kind of experiments are you doing to me?”, “what electronic devices are you using?”, “this is the proof of what I have been constantly saying”.

Conclusions

The symptoms of psychotic relapses could evolve over time. A clinician should refrain from any strictly unnecessary physical contact with an exceedingly paranoid patient, particularly when the latter claims that is the object of “medical experiments”. The elaborative “ability” of such patients could be, simply, astounding.

Long-acting injectable antipsychotics during pregnancy: An update

Introduction

Long-acting injectable (LAI) antipsychotics are related to proven compliance to treatment and more constant medication levels (hence the apparent lower side-effect burden).

Objectives

To highlight the experience with LAI antipsychotic treatment during pregnancy.

Methods

Literature review.

Results

Seven cases are reported. A 35year old with schizophrenia received zuclopenthixole LAI (mostly 200mg/monthly) during both her pregnancies (of healthy girls born at weeks 39 and 40). A 35year old with schizophrenia was under risperidone LAI (25mg/2 weeks) and gave birth to a healthy girl at week 37. Another 35year old (probably with schizophrenia) was on olanzapine LAI (300mg/month during the last quarter of her pregnancy) that led to the birth of a healthy girl at week 40. A 37year old with schizophrenia received paliperidone LAI (100mg/monthly, last injection at week 28) and gave birth to a healthy boy at week 39. Paliperidone LAI (50mg/monthly) was the treatment of another 34year old with schizoaffective disorder that gave birth to a healthy boy at week 40, as well as of a 26year old (263mg/3-monthly), mother of a healthy boy as well (born at an unspecified week of pregnancy). Finally, a 43year old with bipolar disorder was on aripiprazole LAI (300mg/monthly) during her pregnancy that led to the birth of a healthy girl at week 40.

Conclusions

All pregnant women on LAI antipsychotic treatment gave birth to (apparently) healthy babies. LAI doses were mostly low. Long-term follow-up could clarify eventual delayed aftereffects. Based on the literature, LAI antipsychotic treatment could be considered as an option for selected pregnant patients.

Characteristics of completed suicides after Greek financial crisis onset: A comparative time-series analysis study

Severe financial crises could influence a country's suicide trends and characteristics. We aimed to highlight differences among suicide completers before and after the onset of Greece's serious debt crisis of 2010 based exclusively on forensic data. The sample's size permitted a further elaboration by means of a time series analysis too. Data were collected from the Piraeus Department of Forensic Medicine for the period 1992-2016. We extracted information on sociodemographic parameters, psychiatric medication and alcohol intake, suicide method, place and month of suicide. The "after crisis onset" group (2011-2016) was significantly older (p = 0.039)-primarily due to differences in the 55-64 age group-, had more frequently used psychiatric medications (p < 0.001), less often alcohol (p = 0.001) and died more frequently by immolation (p = 0.001). These differences were-almost exclusively-due to changes regarding male suicidal behavior. Time series analysis indicates that no strong increasing trend in total (male + female) suicide count can be observed, despite a local increase in 2009-2010. Antidepressant-positive suicides show an increase after 2010, whereas alcohol-positive suicides show a decrease. Future predicted forecasts for antidepressant-positive suicides indicate a decrease (from 5.6 per year in 2018 to 4.3 per year in 2025) whereas an increase is predicted in alcohol-positive suicides (7.7 per year in 2017, 9.36 per year in 2025). Middle-aged men, compared to middle-aged women, presumably found it harder to adjust to economic hardship after the crisis onset. Finally, comparatively more men than women who died by suicide appear to have started and/or complied with psychiatric treatment after 2010.

Similar or Different Neuropsychological Profiles? Only Set Shifting Differentiates Women With Bipolar vs. Borderline Personality Disorder

There is ongoing debate about the similarities and differences between bipolar disorder (BD) and borderline personality disorder (BPD). Very few studies have concurrently assessed their neuropsychological profile and only on a narrow array of neuropsychological tests. We aimed to investigate the differences of these two patient groups on visual memory, executive function, and response inhibition. Twenty-nine BD patients, 27 BPD patients and 22 controls (all female) were directly compared on paired associates learning (PAL), set shifting (ID/ED), problem solving (SOC), and response inhibition (SSRT) using Cambridge Neuropsychological Test Automated Battery (CANTAB). Rank-normalized outcomes were contrasted in one-way ANOVA tests. Discriminant analysis was finally performed to predict BD or BPD patient status. BD patients performed significantly worse than controls on all tasks. BPD patients performed significantly worse than HC on all tests except SST. Significant differences between the two patient groups were recorded only on ID/ED, where BPD patients performed worse (p = 0.044). A forward stepwise discriminant analysis model based on ID/ED and SOC predicted correctly patients' group at 67.9% of cases. In conclusion, BD and BPD female patients appear to be more similar than different as regards their neuropsychological functions. This study is the first to show that BPD patients display more deficits than BD patients when directly compared on the set shifting executive function test, a marker of cognitive flexibility. Discerning BD from BPD patients through neuropsychological performance is promising but would improve by using additional subtler tests and psychometric evaluation.

Suicides by drowning in Greece: Findings from a 10-year sample (2006-2015)

We studied a sample of suicide victims from Greece's main port of Piraeus area (population: approx. 700,000 individuals) and investigated all suicides for the 10-year period 2006-2015, collecting data from the victims' forensic records at the Piraeus Department of Forensic Medicine. Sixty-nine (15.9%) out of 435 suicides were due to drowning, 51 (73.9%) males and 18 (26.1%) females. Drowning was the third most common suicide method with most in the sea (92.8%), fewer in wells (7.2%). Median age: males 52.2 years (standard deviation (SD): 20.3, range: 27-89) and females 58.8 years (SD: 15.2, range: 32-84). Psychiatric medications: antidepressants (6 cases, 8.9%), benzodiazepines (6 cases, 8.9%) and antipsychotics (1 case, 1.5%). Other substances: alcohol (14 cases, 20.9%), cocaine (1 case, 1.5%) and opioids (1 case, 1.5%). No seasonal effect was observed for suicides by drowning. Greece, being a country with an embracing coastline, could provide a field of study for suicide by drowning.

Antidepressants for Depression Associated with Traumatic Brain Injury: A Meta-analytical Study of Randomised Controlled Trials

INTRODUCTION

Depression following traumatic brain injury is experienced by 16% to 60% of affected patients. The present study aimed to update the best evidence-based pharmacological treatments for tackling such chronic and debilitating disorders.

METHODS

We systematically reviewed and meta-analysed randomised controlled trials published from 1990 until August 2017 that compared the efficacy of antidepressants with placebo in the treatment of post-traumatic brain injury depression. We searched MEDLINE, SCOPUS, and the Cochrane Central Register of Controlled Trials (CENTRAL).

RESULTS

Four studies were eligible for the meta-analysis. The antidepressants studied were the selective serotonin reuptake inhibitors sertraline and citalopram. The rate of non-responders at the end of the follow-up period was lower in the treatment groups compared with placebo (odds ratio = 0.42, 95% confidence interval: 0.15-1.17); this difference was not statistically significant (p = 0.10). In subgroup analysis of the studies that reported mean Hamilton Depression Rating Scale score differences between treatment and control groups in both baseline and endpoint evaluations, the pooled mean difference was reduced from 2.11 (95% confidence interval: -1.25 to 5.46) to -2.36 (95% confidence interval: -5.59 to 0.87), in favour of the treatment group, though not statistically significant (p = 0.06). No evidence of heterogeneity was detected. In the subgroup analysis according to the antidepressant used in the included studies, there was a trend towards statistical significance for sertraline only (odds ratio = 0.28, 95% confidence interval: 0.08-1.03; p = 0.05); this was not evident in the study that reported the use of citalopram (odds ratio = 0.83; 95% confidence interval: 0.15-4.64; p = 0.84).

CONCLUSIONS

Sertraline might be effective, though not statistically significant, in treating patients with post-traumatic brain injury depression. Adequately powered randomised controlled trials - extended to the plethora of newer antidepressants aiming to prove their non-inferiority to the selective serotonin reuptake inhibitors studied - are needed to confirm our results. The dearth of quality studies of this devastating problem of public health is rather impressive.

The Economic Crisis in Greece and Its Impact on the Seasonality of Suicides in the Athens Greater Area

OBJECTIVE

The economic crisis and the implementation of austerity measures in Greece lead to significant socioeconomic changes. The effects of the crisis were mainly felt by the Greek population during the years 2011 and 2012. This study aimed to investigate the impact of Greece's economic crisis on the seasonality of suicides in the Athens Greater Area.

METHODS

Data were collected for all recorded cases of suicides committed over a 5-year period (from 2008 to 2012) from the Athens Department of Forensic Medicine. Two sub-periods were studied in relation to the economic crisis: 2008-2010 and 2011-2012. Seasonality was estimated with the Poison regression variant of the circular normal distribution.

RESULTS

Suicide seasonality appeared significant during 2008-2010 (relative risk, RR=1.36) and strengthened in the years 2011-2012 (RR=1.69), when the impact of the austerity measures was increasingly being felt by the Greek society. Regarding the latter sub-period, seasonality was established for males (RR=1.75), individuals aged 45 years or more (RR=1.75) and suicide by hanging (RR=1.96).

CONCLUSION

The economic crisis in Greece, especially in the period during its effects had a significant impact on the population's economic condition, seems to have strengthened the seasonality of suicides, while a noteworthy suicide risk of 96% was revealed for suicides by hanging (peak in early June).

Characteristics of suicide victims who had verbally communicated suicidal feelings to their family members

BACKGROUND

Verbal expression of suicidal feelings has rarely been investigated in the literature, particularly regarding individuals who died by suicide.

SUBJECTS AND METHODS

We retrospectively collected data on the suicide cases of the period November 2007-October 2009 from the Athens Greater Area and completed psychological autopsy questionnaires after phone interviews with their family members. The specific question was: "Has your relative expressed to you his/her deep suffering or the intention to end his/her life at any time during the six months prior to the suicide?"

RESULTS

Data were collected for 248 individuals who died by suicide out of a total of 335. 121 of them (48.8%) had verbally communicated their intention to die -or their profound suffering- to their family members. Suicide communicators were older (p<0.001), less educated (p=0.04), more frequently divorced or separated and less often single (p<0.01) than non-communicators. They had more often positive psychiatric history (p=0.004) and were less physically well (p=0.005), in comparison to non-communicators. Differences regarding sex, nationality, previous attempts, suicide note-leaving, completed suicide method and hospitalization either for physical illness or psychiatric disorder the year prior to the suicide were not statistically significant among the two groups. Considered that we interviewed only one relative for every case, the actual number of suicide communicators would be probably higher; the suicidal feelings could have been disclosed to another relative instead.

CONCLUSIONS

This is the first time that a similar study was carried out in Greece. We found that approximately half of the individuals who died by suicide in our sample had been (verbal) suicide communicators. The latter seem to present distinct characteristics. These findings, coupled with the observation that the relatives are keen observers of the suicidal feelings of their loved ones, could provide new insights to future suicide prevention efforts.

A 2-year psychological autopsy study of completed suicides in the athens greater area, Greece

OBJECTIVE

To study the characteristics of a sample of suicide victims from the Athens Greater Area using the psychological autopsy method for the first time in Greece.

METHODS

We studied all recorded cases of completed suicide for the 2-year time period November 2007-October 2009 collecting data from the victims' forensic records as well as from the completion of a psychological autopsy questionnaire.

RESULTS

335 persons were recorded as suicide victims. We contacted relatives of 256 victims interviewing those of 248 of them (96.9%). The differences regarding sex, marital and employment status between our sample and the general population were statistically significant (p<0.001). The male/female ratio was 3:1. Comparatively more victims were divorced, separated or single and a greater proportion were pensioners or unemployed. 26.0% of the victims had history of prior attempts (64.4% once, 20.3% twice and 15.3% more times). 42.6% were taking psychiatric medication-significantly more women than men according to blood tests; 14.2% had been hospitalized in a psychiatric clinic the year prior to their death. 84.8% have deceased at the place of suicide and 15.2% died in the hospital; 80.3% died indoors and 19.7% outdoors. Men died primarily by hanging or shooting by a firearm while women preferred jumping from height instead (p<0.001). As many as 48.8% had expressed their intention to die to their relatives; 26.6% left a suicide note.

CONCLUSION

Our study has shown that the psychological autopsy method is applicable and widely accepted yielding results comparable to the international literature. Specific parameters associated with suicide have been studied for the first time in Greece.

Characteristics of immigrant suicide completers in a sample of suicide victims from Greece

BACKGROUND

Immigrants have higher rates of suicidal behaviour in comparison to the indigenous population.

AIMS

To describe the characteristics of foreign nationality suicide completers and search for differences between them and native Greeks. This is the first study focused on immigrant suicide victims in Greece.

METHODS

Data were collected for all recorded cases of completed suicide for the two-year period November 2007 to October 2009 at the Athens Department of Forensic Medicine, the largest, by far, of its kind in Greece covering approximately 35% of the country's population. The material was collected using the method of psychological autopsy as well as from the victims' forensic records.

RESULTS

Nearly 10% of Greece's 11 million population are of foreign nationality. Approximately half of them live in Athens and its suburbs, an area where 35% of Greece's population lives. In our sample, 15.8% of the suicide victims were of foreign nationality (53 cases): 41 men (77.4%) and 12 women (22.6%). Higher suicide rates were found for citizens of Kuwaiti (9.1%), Somali (6.7%) and Afghan (0.9%) nationality (immigrant communities with very few members); the lower suicide rates were for individuals of Egyptian (0.01%), Ukrainian (0.01%) and Albanian (0.006%) nationality (the Albanian immigrant community is the largest in Greece). In comparison to their Greek counterparts, immigrant victims were younger (mean age 38.7 vs 54.9 years, p < .001) more often unemployed (p = .007) and with a history of alcohol abuse (p < .001). The main suicide method used by immigrants was hanging (p < .001) while for Greeks it was jumping from a height.

CONCLUSIONS

Individuals who belong to small national communities seem to have the highest risk of dying by suicide. Immigrant suicide victims differ from the indigenous population in several parameters. Our data could help define the most vulnerable of them and apply more effective suicide prevention strategies.

Switching suicide methods in order to achieve lethality: a study of Greek suicide victims

This article focused on the relation between the method of last attempted suicide and the method used during the subsequent completed suicide. Using the method of psychological autopsy, the authors studied all suicide cases from the Athens Greater Area during a 2-year period. Twenty-four percent of the victims had history of previous suicide attempts. The majority of the suicide attempters switched to a different method (p < 0.001) for their final act. This difference is primarily due to the individuals who had chosen self-poisoning or wrist cutting in their last attempted suicide. Both of these groups switched to hanging or jumping from a height for their final attempt. Individuals who attempted suicide by hanging or jumping became completers using mainly the same methods.

Differences Between Suicide Victims Who Leave Notes and Those Who Do Not

Background: Whether differences exist between those who do leave a suicide note and those who do not has not yet been comprehensively answered. Leaving a suicide note is not a random phenomenon: A minority, varying between 3–42%, of all suicide victims leave a note. Aims: To compare the group of suicide victims who leave notes with the ones who do not, using data from the Athens Department of Forensic Medicine, the largest in Greece. Methods: We examined sex, age, nationality, religious beliefs, marital and residential status, history of prior psychiatric disorder and psychiatric attempt(s), suicide method, physical disease, recent hospitalization, and existence of suicide notes. We completed psychological autopsy questionnaires after phone interviews with relatives of the suicide victims of a 2-year period (November 2007–October 2009). Results: Note writers, 26.1% of our sample, differed in the following: they died by hanging or shooting (p = .007), had no history of psychiatric illness (p < .001) or recent (i.e., within 12 months of the suicide) psychiatric hospitalization (p = .005). Conclusions: Our study showed that there are indeed differences between suicide victims who leave a note and those who do not. We also suggest some explanations for these differences, which could represent a valuable starting point for future research on this topic.

Late onset suicide: distinction between "young-old" vs. "old-old" suicide victims. How different populations are they?

Elderly suicide rates are the highest of any age group. Greece is among the countries with the highest proportion of elderly people in the European Union (EU). Elderly suicide victims seem to possess different characteristics. Aim of our study was to elucidate the different characteristics of elderly suicide victims. Data was collected from a two-year psychological autopsy study, conducted at the Athens' Department of Forensic Medicine, the largest in Greece. Elderly suicide victims represented 35% of total suicides. The majority (69.5%) were males. Only 12.4% had previous psychiatric hospitalization but more than half (65.2%) had psychiatric history (81% of them had history of depression). As expected, there was a high incidence of physical illness (81.6%). The majority (82%) of the elderly suicide victims made a suicide attempt for the first time and it was unfortunately successful. When the elderly suicide victims were divided in two categories ("young-old" and "old-old") the differences between the two groups were: elderly over 75 years had more physical problems and more frequently positive psychiatric history without ever been hospitalized for psychiatric problems. Late life suicides seem to encapsulate population groups with different characteristics. Their differences can be a useful guide aiming to formulate specific suicide prevention strategies. This is of great importance, given the very high frequency of completed suicides in this age group.

Male depression: Discrete differences between the two sexes

Recent research indicates that subtle differences may exist in the symptom profile of male and female depression. The aim of this review is to examine male/female differences in depressive psychopathology in light of the latest research findings and discuss whether these differences might suggest the need for gender specific treatments. Multiple searches using Medline (1985-2008) were carried out. Additional searches were made using the reference lists of published papers and chapters from books. Differences exist in the clinical profile and comorbidity of male and female individuals with depression. Subtle genetic differences, the role of hormones, the role of preexisting anxiety, and personality differences are some of the factors responsible for these findings. These differences imply that different treatment options should be available for males and females suffering from depression. The available data suggest that clinically relevant differences in depressive symptom profile and the underlying pathophysiology between genders in depression do exist. The identification of distinct endophenotypes for major depression, will not only improve our understanding of the disease, but will also contribute to more specific treatment strategies.
