Background: Although immigrants are considered to be vulnerable to mental illness, there is limited knowledge regarding their suicide mortality., Aims: To investigate standardised mortality ratios (SMR) for suicide among the largest immigrant populations in Germany before and after the refugee movement of 2015., Method: Data on immigrants and the general population in Germany between 2000 and 2020 were provided by the scientific section of the Federal Statistical Office. SMR with 95% confidence intervals were calculated by indirect standardisation for gender, age and calendar year for the pre-2015 and post-2015 time interval, first for all the immigrant populations studied and second for the Syrian, Afghan and Iraqi populations separately., Results: Immigrants from the countries studied showed a lower suicide risk compared with the German reference population (SMR = 0.38, 95% CI = 0.35-0.41). No differences in SMR were found between pre- and post-2015 time intervals, in either the aggregate data for all populations or the data for Syrian, Afghan and Iraqi populations. Post-2015, Afghan immigrants (SMR = 0.68, 95% CI = 0.54-0.83) showed a higher SMR than Syrians (SMR = 0.30, 95% CI = 0.25-0.36) or Iraqis (SMR = 0.37, 95% CI = 0.26-0.48)., Conclusions: Despite the many and varied stresses associated with flight, comparison of the pre- and post-2015 time intervals showed that the suicide risk of the populations studied did not change and was considerably lower than that of the German reference population. We attribute this to lower suicide rates in the countries of origin but also to flight-related selection processes that favour more resilient individuals.

Aims: The later phase of the COVID-19 pandemic overlaps with geopolitical and economic consequences from the Ukraine war. Financial hardship and concerns about gas supply may add to pandemic factors and lead to increased suicide rates in Germany., Methods: Age- and sex-stratified suicide data from police crime statistics covering 35 % of the German population were used for an interrupted time-series analysis and for a projection of total German suicides in 2022., Results: For both sexes, a trend reversal from constant or declining suicide rates to an increase was observed. This increase is particularly pronounced in 2022 and mainly relates to the 60+ age group that is highly vulnerable to suicide. The projection of the overall German suicide rate is at a level last observed in 2015., Conclusions: The key challenge now is to combat potential causes of this rise in suicide rates to avert the emerging upward trend., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 Elsevier B.V.

Objective: Prisoners constitute a high-risk group for suicide, with suicide rates about 5 to 8 times higher than in the general population. The first weeks of imprisonment are a particularly vulnerable time, but there is limited knowledge about the risk factors for either early or late suicide events., Methods: Based on a national total sample of prison suicides in Germany between 2005 and 2017, suicides within the first 2 (4 and 8) weeks after reception into prison were matched by age and penalty length with cases that occurred later. Factors that potentially influence the timing of suicide were investigated., Results: The study has shown that 16.7% (31.5%) of all 390 suicides in German prisons occurred within the first two weeks (two months) of imprisonment. Factors that facilitate adaptation to the prison environment (e.g. prior prison experience) were negatively associated with early suicide events. Factors that hindered the adaptation process (e.g. withdrawal from illicit drugs) were observed more frequently in early suicide events than in late ones. These factors are active at different times of imprisonment., Conclusion: At reception, particular attention should be paid to the following factors associated with early suicide events: widowed marital status, lack of prison experience, and drug dependency., Competing Interests: The authors have declared that no competing interests exist.

Background: The COVID-19 pandemic is having profound mental health consequences for many people. Concerns have been expressed that, at their most extreme, these consequences could manifest as increased suicide rates. We aimed to assess the early effect of the COVID-19 pandemic on suicide rates around the world., Methods: We sourced real-time suicide data from countries or areas within countries through a systematic internet search and recourse to our networks and the published literature. Between Sept 1 and Nov 1, 2020, we searched the official websites of these countries' ministries of health, police agencies, and government-run statistics agencies or equivalents, using the translated search terms "suicide" and "cause of death", before broadening the search in an attempt to identify data through other public sources. Data were included from a given country or area if they came from an official government source and were available at a monthly level from at least Jan 1, 2019, to July 31, 2020. Our internet searches were restricted to countries with more than 3 million residents for pragmatic reasons, but we relaxed this rule for countries identified through the literature and our networks. Areas within countries could also be included with populations of less than 3 million. We used an interrupted time-series analysis to model the trend in monthly suicides before COVID-19 (from at least Jan 1, 2019, to March 31, 2020) in each country or area within a country, comparing the expected number of suicides derived from the model with the observed number of suicides in the early months of the pandemic (from April 1 to July 31, 2020, in the primary analysis)., Findings: We sourced data from 21 countries (16 high-income and five upper-middle-income countries), including whole-country data in ten countries and data for various areas in 11 countries). Rate ratios (RRs) and 95% CIs based on the observed versus expected numbers of suicides showed no evidence of a significant increase in risk of suicide since the pandemic began in any country or area. There was statistical evidence of a decrease in suicide compared with the expected number in 12 countries or areas: New South Wales, Australia (RR 0·81 [95% CI 0·72-0·91]); Alberta, Canada (0·80 [0·68-0·93]); British Columbia, Canada (0·76 [0·66-0·87]); Chile (0·85 [0·78-0·94]); Leipzig, Germany (0·49 [0·32-0·74]); Japan (0·94 [0·91-0·96]); New Zealand (0·79 [0·68-0·91]); South Korea (0·94 [0·92-0·97]); California, USA (0·90 [0·85-0·95]); Illinois (Cook County), USA (0·79 [0·67-0·93]); Texas (four counties), USA (0·82 [0·68-0·98]); and Ecuador (0·74 [0·67-0·82])., Interpretation: This is the first study to examine suicides occurring in the context of the COVID-19 pandemic in multiple countries. In high-income and upper-middle-income countries, suicide numbers have remained largely unchanged or declined in the early months of the pandemic compared with the expected levels based on the pre-pandemic period. We need to remain vigilant and be poised to respond if the situation changes as the longer-term mental health and economic effects of the pandemic unfold., Funding: None., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2021 Elsevier Ltd.

Aims: It remains unclear whether the coronavirus disease 2019 (COVID-19) pandemic is having an impact on suicide rates (SR). Economic insecurity and mental disorders are risk factors for suicide, which may increase during the pandemic., Methods: Data on suicide events in a major city in Germany, and the corresponding life years (LY) were provided by the local authorities. For the year 2020, periods without restrictions on freedom of movement and social contact were compared with periods of moderate and severe COVID-19 restrictions. To avoid distortions due to seasonal fluctuations and linear time trends, suicide risk during the COVID-19 pandemic was compared with data from 2010 to 2019 using an interrupted time series analysis., Results: A total of 643 suicides were registered and 6 032 690 LY were spent between 2010 and 2020. Of these, 53 suicides and 450 429 LY accounted for the year 2020.In 2020, SR (suicides per 100 000 LY) were lower in periods with severe COVID-19 restrictions (SR = 7.2, χ2 = 4.033, p = 0.045) compared with periods without restrictions (SR = 16.8). A comparison with previous years showed that this difference was caused by unusually high SR before the imposition of restrictions, while SR during the pandemic were within the trend corridor of previous years (expected suicides = 32.3, observed suicides = 35; IRR = 1.084, p = 0.682)., Conclusions: SR during COVID-19 pandemic are in line with the trend in previous years. Careful monitoring of SR in the further course of the COVID-19 crisis is urgently needed. The findings have regional reference and should not be over-generalised.

Purpose: Prisoners have a higher risk of suicide compared to non-incarcerated individuals. One aim of suicide prevention for prisoners is to identify risk factors in order to put stronger support mechanisms in place for the more vulnerable detainees. This study investigates the suicide risk (SR) in offence-related sub-populations in a representative German sample and differentiates between SR for adolescent and adult prisoners., Methods: Conducting a national study with data from public German records on the entire prison population from 2000 to 2016 and suicide numbers in German prisons in the same period, SR was calculated for the total male prison population as well as for both subgroups, adolescent and adult male prisoners., Results: In the study period, male prisoners spent 959.584 life years (LY) in German criminal detention. Among those, 524 prisoners died of suicide. SR was higher for detainees imprisoned for an offence resulting in extensive physical harm for another person, e.g. homicide (suicide rate = 134,8 suicides per 100.000 LY; OR = 2,47; CI95%: 1,98-3,08), bodily injury (suicide rate = 87,3; OR = 1,60; CI95%: 1,29-1,99), and sexual offences (suicide rate = 84,2; OR = 1,54; CI95%: 1,18-2,01) compared with the SR of the total prison population (suicide rate = 54.6). Age differences between offence-related SR were found for theft, with adolescents (suicide rate = 69,3; OR = 1,25; CI95%: 0,85-1,84) showing higher SR than adults (suicide rate = 38,2; OR = 0,7; CI95%: 0,54-0,92)., Conclusion: The index offence of detainees is associated with SR and age-related differences exist. Suicide prevention in prisons should take both into account to determine populations at risk., Competing Interests: MK received funding by the German Federal Ministry of Health. This does not alter our adherence to PLOS ONE policies on sharing data and materials. All other authors have declared that no competing interests exist.

Purpose: Prisoners are at a particularly high risk of suicide. In contrast to other psychosocial risk factors it remains unclear to what degree the risk of suicide differs between prisoners with local citizenship and foreigners. In order to provide more detailed information for suicide prevention in prisons, this study aims to compare suicide rates (SR) between these populations in German criminal custody., Methods: Based on a German national database of completed suicide in custody, suicides by prisoners were analysed and compared with epidemiological data of the prison population and the general population, stratified for German and foreign citizenship. Data analysis was adjusted for differences in the age distribution of both populations by calculating standard mortality ratios (SMR) for suicide., Results: SR were higher in prisoners with German citizenship than those with foreign citizenship (SR = 76.5 vs. SR = 42.8, P<0.01). This association was not specific to the prison population, as the higher SR in citizens compared to non-citizens (SR = 19.3 vs. SR = 9.0, P<0.01) were also found in the general population. The association between prison suicide and citizenship was comparable in juvenile and adult prisoners, indicating its relevance to both the juvenile and adult detention systems., Conclusion: Imprisonment is associated with a substantially increased risk of suicide in both German and non-German citizens, a finding which needs to be taken into consideration by the justice system. The lower suicide risk in non-German citizens is independent of whether or not they are in custody.

Because of neurocognitive impairments in perinatally human immunodeficiency virus (HIV)-infected children and adolescents, this study aimed to demonstrate the effect of plasma viral loads and early initiation of sufficient combined antiretroviral therapy (cART) on neurocognitive development.In total, 14 perinatally infected HIV-positive children (median age 8.24 years [range: 6.0-16.74]) receiving lopinavir/ritonavir (LPV/r)-based ART underwent neurocognitive testing using the Wechsler Intelligence Score for Children, 4th Edition (WISC-IV). All 14 patients participated in a pharmacokinetic study in which they were hospitalized for an entire day. As a child's ability to concentrate varies over the course of the day, all tests were performed in the morning.The patients' neurocognitive development did not significantly differ from the normative collective pattern for any of the following composite scores that were examined: full-scale intelligence quotient (IQ) (mean: 106.5, P = .1060), verbal comprehension index (mean: 106.0, P = .1356), perceptual reasoning index (mean: 106.0, P = .1357), working memory index (mean: 106.3, P = .1171), and processing speed index (mean: 98.1, P = .6313). The overall full-scale IQ scores were significantly higher in children who began ART within the first year of life (P = .0379), whereas low lopinavir/r plasma levels (P = .0070) and high viral load area under the curves (AUCs) in the first 3 years of life, but not later, significantly correlated with reduced neurocognitive performance (Spearman r = -0.64, P = .0278).In this cohort of cART treated HIV-positive children and adolescents, neurocognitive performance correlated with early and sufficient viral load suppression within the first 3 years of life.

Autism spectrum disorder and schizophrenia share a substantial number of etiologic and phenotypic characteristics. Still, no direct comparison of both disorders has been performed to identify differences and commonalities in brain structure. In this voxel based morphometry study, 34 patients with autism spectrum disorder, 21 patients with schizophrenia and 26 typically developed control subjects were included to identify global and regional brain volume alterations. No global gray matter or white matter differences were found between groups. In regional data, patients with autism spectrum disorder compared to typically developed control subjects showed smaller gray matter volume in the amygdala, insula, and anterior medial prefrontal cortex. Compared to patients with schizophrenia, patients with autism spectrum disorder displayed smaller gray matter volume in the left insula. Disorder specific positive correlations were found between mentalizing ability and left amygdala volume in autism spectrum disorder, and hallucinatory behavior and insula volume in schizophrenia. Results suggest the involvement of social brain areas in both disorders. Further studies are needed to replicate these findings and to quantify the amount of distinct and overlapping neural correlates in autism spectrum disorder and schizophrenia.

Objectives: Individuals with anorexia nervosa (AN) and bulimia nervosa (BN) tend to have disordered thinking and eating behaviours in regards to fat containing foods. This is the first study to investigate neuronal pathways that may contribute to altered fat consumption in eating disordered patients., Methods: We used functional magnetic resonance imaging (fMRI) to compare responses to a high-fat cream stimulus, water, and a non-caloric viscous stimulus (CMC) to control for response to viscosity in individuals recovered from AN (N = 15), BN (N = 14) and a healthy control sample (CW, N = 18)., Results: An interaction analysis (ANOVAR) comparing the three groups (AN, BN, CW) and the three conditions (cream, CMC, water) revealed significant differences in the left anterior ventral striatum (AVS). A post hoc analysis displayed a higher magnitude of response for the contrast cream/water in BN compared to AN or CW and for the contrast CMC/water in BN compared to AN., Conclusions: BN showed an exaggerated AVS response for the cream/water contrast in comparison to AN or CW. Moreover, BN showed an exaggerated AVS response for the CMC/water contrast in comparison to AN. These findings support the possibility that BN have an altered hedonic and/or motivational drive to consume fats.

Purpose: To establish an estimate for the mean pulmonary arterial pressure (mPAP) derived from noninvasive data acquired with magnetic resonance (MR) velocity-encoded sequences., Materials and Methods: In seven sedated pigs synchronous catheter-based invasive pressure measurements (IPM) and noninvasive MR were acquired in the main pulmonary artery (MPA) at different severities of pulmonary arterial hypertension (PAH) that were caused by infusion of thromboxane A2 (TxA2). The invasively measured mPAP was correlated with the noninvasive MR velocity data and linear combination equations (LCE) were computed., Results: Intravenously applied TxA2 induced a dose dependent level of severity of PAH with an mPAP of up to 54 mmHg without systemic effects. The acceleration time (AT) measured with MR demonstrated the best correlation with the mPAP (r(2) = 0.75). The LCE with the highest correlation (R = 0.945, alpha < 0.01) between IPM and MR revealed a mean difference of 0, a SD of s = 4.66 and a maximal difference of 12.2 mmHg using the Bland-Altman analysis., Conclusion: Applying the identified LCE allowed the estimation of the mPAP in an acute and resistance-based model of PAH with high accuracy using noninvasive MR velocity-encoded sequences., ((c) 2007 Wiley-Liss, Inc.)

In this color study females reported a favorite color significantly more often than males. Males preferred bright colors significantly more than females, with a converse finding for preference for soft colors. The 276 subjects, when asked to evaluate the attractiveness of stimulus models in photographs, gave as the reason color significantly more often than style of clothing or facial expressions. Subjects significantly concurred with expert choices of recommended and nonrecommended colors in five of the six sets of photographs. This study lends credence that wearing recommended colors makes a difference in judgments of what looks best by subjects over the age of 12.
