Additive effects between prematurity and postnatal risk factors of suicidal behavior

Adverse childhood experiences (ACEs), excessive alcohol use and intimate partner violence (IPV) perpetration among Black men: A latent class analysis

BACKGROUND

Adverse childhood experiences (ACEs) have been linked to subsequent intimate partner violence (IPV) perpetration and alcohol use. Although higher rates of ACEs are found in racial/ethnic minority populations, there is a paucity of research examining ACEs patterns and risk for IPV perpetration and excessive alcohol use among Black men.

OBJECTIVE

To identify homogeneous subgroups based on ACEs among Black men using latent class analysis and assessing risk for later IPV perpetration and excessive alcohol consumption in adulthood.

METHODS

Using a sample of Black men (n = 2306) from Wave 2 of the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC), we conducted latent class analysis (LCA) to examine their ACEs patterns based on 10 domains. ACE classes were used in logistic regression models to predict IPV perpetration and unhealthy alcohol use.

RESULTS

LCA revealed three classes: (1) High Household Dysfunction & Physical Neglect; (2) Physical/Emotional Abuse; and (3) Low ACEs. Men in the High Household Dysfunction & Physical Abuse (OR = 3.95, p < 0.001), and Physical/Emotional Abuse (OR = 2.37, p < 0.001) classes had increased risk for IPV perpetration (ref: Low ACEs class) controlling for sociodemographic factors. No significant association was found between class membership and unhealthy alcohol use.

CONCLUSIONS

Our findings highlight the need for interventions aimed at addressing ACEs among Black boys as they increase risk for negative outcomes in adulthood. Future research should explore heterogeneity in ACEs among youth and risk of IPV and explore possible causal mechanisms in the development of IPV among adults who have experienced ACEs.

Serum β-endorphin levels are associated with addiction to suicidal behavior: A pilot study

The literature provides partial support for the hypothesis that some suicide attempters develop a behavioral addiction to suicidal behavior (SB). We hypothesized that major suicide repeaters (MR) (≥5 lifetime suicide attempts) are addicted to suicide attempts as measured by modified DSM-IV criteria for substance dependence. In this cross-sectional study with 13 psychiatric controls (PC), 55 non-major suicide attempters (NMR), and 9 MR we found that MR are characterized by emotional abuse and neglect, as well as higher scores on the Personality and Life Event scale (short version). The levels of 8 AM serum ACTH, cortisol and β-endorphin were elevated in all three groups. Serum β-endorphin (pg/mL) was particularly high in PC diagnosed with schizophrenia 220.34 (±56.30). The level of 8 AM serum β-endorphin rose with increased numbers of criteria met for addiction to SB from 130.31 (±88.16) (≥ 3 criteria met for addiction to SB) to 174.84 (±114.93) (≥ 6 criteria met for addiction to SB) whereas serum ACTH and cortisol did not change. SB addicts (≥ 6 criteria) displayed higher serum β-endorphin concentrations than non-addicts (174.84 ± 114.93 vs. 116.93 ± 61.70, FET p = 0.09). The present study brings some support to the addictive hypothesis of SB. Our results delineate β-endorphin as a promising biomarker of SB addiction, and offer a good basis for future studies that test whether buprenorphine can be used to prevent repetitive suicide attempts, non-suicidal-self-injury (NSSI), and the development of an addiction to SB.

ABCB1 gene polymorphisms and violent suicide attempt among survivors

INTRODUCTION

Those suicide attempters that choose violent methods dramatically diminish the possibility of survival. Completed suicide using violent means, which is common among first-time suicide attempters, was recently found to be more likely among T allele carriers in the three most common ABCB1 SNPs, encoding for P-gp. Thus, this study examined, for the first time, whether these ABCB1 SNPs were associated with the use of violent means among survivors of a suicide attempt.

MATERIAL AND METHODS

Suicide attempters (n = 578, 87.4% women; of whom 16.6% committed a violent intent) were genotyped for exonic SNPs in the ABCB1 (C1236T, G2677T/A, C3435T). The relations of the three genotypes and of the TTT haplotype with the use of a violent suicide method were evaluated separately. The impact of confounds on these variables was controlled.

RESULTS

A higher frequency (p = 0.02) of suicide attempters using violent methods was found among those carrying the ABCB1 haplotype (1236TT-2677TT-3435TT). Since gender and number of previous suicide attempts were identified as confounds, the relation was tested in the subset of women who were first-time attempters or second- and more-time attempters. The ABCB1 haplotype increased the risk more than three times in those women attempting a violent suicide for the first time (OR = 3.6; CI95%: 1.08-12.09; p = 0.04).

DISCUSSION

The ABCB1 haplotype (1236TT-2677TT-3435TT) was related to the use of a violent suicide attempt method. Genotyping for these three ABCB1 SNPs may be helpful to detect people at risk of first suicide intents using violent methods.

Maternal Experiences of Their Unborn Child's Spiritual Care: Patterns of Abstinence in Iran

Preparing for pregnancy and childbirth has significant association with spirituality. Review of the literature shows that the spirituality of the "unborn child" has not yet attracted much critical attention. This study was conducted with the aim of exploration of maternal behaviors associated with the spiritual health of the unborn child. A qualitative approach was used to investigate the research question. Twenty-seven in-depth unstructured interviews were conducted with 22 Iranian mothers in Tehran city (Iran) who were pregnant or had experienced pregnancy in 2012-2013. Data analysis was carried out using a conventional content analysis approach. "Refusing to eat forbidden food," "Overcoming mental adversity," "Regulating one's social interactions," "Preventing the effects of harmful environments on the senses," "Avoidance of using insulting and abusive language," "Keeping one's mind and spirit free from evil traits," and "Refraining from damaging behaviors" were important experiences that the mothers used for "Holistic Abstinence." The results provide new information about the subjective experiences of Iranian women on the patterns of abstinence for the midwives, research community, policy makers, and planners of maternal and child health care services in order to contribute to holistic, culturally, and religiously competent prenatal care for Muslim pregnant women throughout the world.
