The effects of experience of discrimination and acculturation during pregnancy on the developing offspring brain.

The experience of ethnic, racial, and structural inequalities is increasingly recognized as detrimental to health, and early studies suggest that its experience in pregnant mothers may affect the developing fetus. We characterized discrimination and acculturation experiences in a predominantly Hispanic sample of pregnant adolescent women and assessed their association with functional connectivity in their neonate's brain. We collected self-report measures of acculturation, discrimination, maternal distress (i.e., perceived stress, childhood trauma, and depressive symptoms), and socioeconomic status in 165 women. Then, we performed a data-driven clustering of acculturation, discrimination, perceived stress, depressive symptoms, trauma, and socioeconomic status variables during pregnancy to determine whether discrimination or acculturation clustered into distinct factors. Discrimination and acculturation styles loaded onto different factors from perceived stress, depressive symptoms, trauma, and socioeconomic status, suggesting that they were distinct from other factors in our sample. We associated these data-driven maternal phenotypes (discrimination and acculturation styles) with measures of resting-state functional MRI connectivity of the infant amygdala (n = 38). Higher maternal report of assimilation was associated with weaker connectivity between their neonate's amygdala and bilateral fusiform gyrus. Maternal experience of discrimination was associated with weaker connectivity between the amygdala and prefrontal cortex and stronger connectivity between the amygdala and fusiform of their neonate. Cautiously, the results may suggest a similarity to self-contained studies with adults, noting that the experience of discrimination and acculturation may influence amygdala circuitry across generations. Further prospective studies are essential that consider a more diverse population of minoritized individuals and with a comprehensive assessment of ethnic, racial, and structural factors.

Brain serotonin 1A receptor binding: relationship to peripheral blood DNA methylation, recent life stress and childhood adversity in unmedicated major depression.

BACKGROUND: Childhood and lifetime adversity may reduce brain serotonergic (5-HT) neurotransmission by epigenetic mechanisms. AIMS: We tested the relationships of childhood adversity and recent stress to serotonin 1A (5-HT1A) receptor genotype, DNA methylation of this gene in peripheral blood monocytes and in vivo 5-HT1A receptor binding potential (BPF) determined by positron emission tomography (PET) in 13 a priori brain regions, in participants with major depressive disorder (MDD) and healthy volunteers (controls). METHOD: Medication-free participants with MDD (n = 192: 110 female, 81 male, 1 other) and controls (n = 88: 48 female, 40 male) were interviewed about childhood adversity and recent stressors and genotyped for rs6295. DNA methylation was assayed at three upstream promoter sites (-1019, -1007, -681) of the 5-HT1A receptor gene. A subgroup (n = 119) had regional brain 5-HT1A receptor BPF quantified by PET. Multi-predictor models were used to test associations between diagnosis, recent stress, childhood adversity, genotype, methylation and BPF. RESULTS: Recent stress correlated positively with blood monocyte methylation at the -681 CpG site, adjusted for diagnosis, and had positive and region-specific correlations with 5-HT1A BPF in participants with MDD, but not in controls. In participants with MDD, but not in controls, methylation at the -1007 CpG site had positive and region-specific correlations with binding potential. Childhood adversity was not associated with methylation or BPF in participants with MDD. CONCLUSIONS: These findings support a model in which recent stress increases 5-HT1A receptor binding, via methylation of promoter sites, thus affecting MDD psychopathology.

Victimology of Mass Shootings and Mass Murders Not Involving Firearms.

Most research to date has focused on perpetrators of mass murder incidents. Hence, there is little information on victims. We examined 973 mass murders that occurred in the United States between 1900 and 2019 resulting in 5,273 total fatalities and 4,498 nonfatal injuries for a total of 9,771 victims (on average 10 victims per incident). Approximately 64% of victims of mass murder were White individuals, 13% were Black individuals, 6% were Asian individuals, and 14% were Latinx individuals. Given the higher number of nonfatal injuries per non-firearm mass murder event (11.0 vs. 2.8, p < .001), the total number of victims was only 50% higher for mass shootings (5,855 victims) vs. non-firearm mass murder events (3,916 victims). Among the 421 incidents of mass murder in the United States since 2000, Black, Asian, and Native American individuals were overrepresented among victims of mass shootings compared with their representation in the general U.S. population, and White individuals were underrepresented (all p ≤ .002). Findings of racial/ethnic differences were similar among victims of mass murder committed with means other than firearms for Black, Asian, and White individuals. These findings highlight different areas of victimology within the context of these incidents.

Impact of an Evidence-Based Pediatric Palliative Care Program on Nurses' Self-Efficacy.

Background The purpose of this study was to determine the effect of a 1-day evidence-based pediatric palliative care continuing professional development program on nurses' and advanced practice registered nurses' perceived self-efficacy regarding palliative care. Method The revised Pediatric Palliative Care Questionnaire was administered to participants before and after a 7½-hour program. A multimodal approach was used to teach topics specific to pediatric palliative care. Results Thirty-one participants completed questionnaires. Notably, most of the participants had provided palliative or end-of-life care, but few had previous education specific to pediatrics. The self-efficacy scores of the participants significantly increased after program attendance (Z = 3.53, p < .001). Conclusion Continuing professional development in pediatric palliative care improves nurses' and advanced practice registered nurses' confidence in their skills to provide this care. Findings of this study support the need for pediatric-specific education in nursing training programs and continuing professional development offerings. Continuing education may be the key to improving access to high-quality care for children living with serious illness and their families. [J Contin Educ Nurs. 2022;53(6):264-272.].

Gender self-concept and hazardous drinking among sexual minority women: Results from the Chicago health and life experiences of women (CHLEW) study.

OBJECTIVE: Sexual minority women (SMW; e.g., lesbian, bisexual) report substantially higher rates of hazardous drinking (HD) than heterosexual women.Yet, few studies have examined sub-group differences. In this study, we investigated the relationship between gender self-concept and HD among SMW. Research consistently shows a link between heavier drinking and masculinity. SMW are more likely than heterosexual women to be gender nonconforming, and masculinity among SMW is associated with increased minority stress, a key HD risk factor. METHODS: We used Wave 3 data from the Chicago Health and Life Experiences of Women study, a longitudinal study of SMW (N = 598), which assessed participants' self-perceived levels of masculinity and femininity and their perception of how masculine/feminine others viewed them. Using multivariable logistic regression, we examined the association between gender self-concept and past 12-month heavy episodic drinking (HED), drinking-related problems, and alcohol dependence. RESULTS: Controlling for demographics and minority stress, greater masculinity (both self-perceived and perceptions by others) was associated with higher odds of HED and alcohol dependence. Masculinity as perceived by others was associated with higher odds of drinking-related problems. Neither femininity measure was associated with HD. Additionally, minority stress (i.e., discrimination, stigma, internalized stigma) did not account for the relationship between gender self-concept and HD. CONCLUSIONS/IMPORTANCE: In this sample, masculinity, particularly SMW's beliefs that others viewed them as masculine, was associated with HD. This association was not attributable to differences in minority stress and may be related to differences in gendered drinking norms, which could be targeted in intervention studies.

Screening for depression with the PHQ-9 in young adults affected by HIV.

BACKGROUND: Major depressive disorder (MDD) is common among young adults with perinatally acquired HIV (YAPHIV), however it is often underdiagnosed and untreated. The PHQ-9 and PHQ-2 are widely used screening instruments for MDD. This study evaluates the accuracy of recommended PHQ-9 and PHQ-2 cut-scores of 10 and 3 for YAPHIV and YA who were perinatally HIV exposed but uninfected (YAPHEU). METHODS: The PHQ-9 was administered to participants (n = 203) in a longitudinal cohort study using the DISC-IV as the gold standard for diagnosing depression. PHQ-9 and PHQ-2 sensitivity and specificity were calculated. ROC curves were constructed for the overall sample and YAPHIV and YAPHEU subsamples. RESULTS: Almost all participants were Black and Latinx, ages 18-29. Overall, the recommended PHQ-9 cut-score of ≥10 yielded a sensitivity of 0.47 (95%CI [0.23,0.72]) and specificity of 0.86 (95%CI [0.80, 0.91]). Results indicate that PHQ-9 cut-scores of 7 and PHQ-2 cut-scores of 2 increased sensitivity to 0.76 (95%CI [0.50, 0.93]) and 0.71(95%CI [0.44,0.90]), and decreased specificity to 0.72 (95%CI [0.65, 0.79]) and 0.73 (95%CI [0.66, 0.79]) respectively. Among subsamples, existing PHQ-9 cut-scores were more accurate for MDD diagnoses in YAPHEU (N = 11) than YAPHIV(N = 6). No race/ethnicity or age differences were found. LIMITATIONS: Participants were recruited from clinics in NYC and may not reflect all YAPHIV and YAPHEU. Without a white HIV comparison group, no conclusions could be made on the impact of race/ethnicity on optimized PHQ-9 cut-scores. CONCLUSIONS: Using tailored cut scores for HIV-affected populations may increase identification of those experiencing or at risk for MDD. Given the need for increased depression screening in HIV care, use of optimized cut-scores could benefit at-risk populations in the US and globally.

Preparing for the Impact of COVID-19 on the Mental Health of Youth.

The COVID-19 pandemic is continuing to have long-term and global effects that the vaccine may not ease. Children and adolescents endured unprecedented periods of loneliness, social isolation, financial stressors, in-home conflicts, changes in living circumstances, and variable access to healthcare, resulting in increased mental health sequelae. Timely recognition of students' anxiety, depression, and disruptive behaviors will allow appropriate interventions to de-escalate these feelings and prevent suicidal ideations and attempts. As youth return to school, their mental health needs will not subside. School nurses and the multidisciplinary team have a vital role in impacting this population's already surging increase of mental and behavioral health disorders.

Predictors of Attempted Suicide Among Youth Living With Perinatal HIV Infection and Perinatal HIV-Exposed Uninfected Counterparts.

BACKGROUND: Suicide is a leading cause of death among adolescents and young adults (AYA). AYA living with perinatally acquired HIV infection (AYALPHIV) are at higher risk of attempted suicide when compared with AYA who were perinatally HIV-exposed but uninfected (AYAPHEU). To inform interventions, we identified risk and protective factors of attempted suicide among AYALPHIV and AYAPHEU. SETTING: Data were obtained from a longitudinal New York City-based study of AYALPHIV and AYAPHEU (n = 339; enrollment age 9-16 years) interviewed approximately every 12-18 months. METHOD: Our main outcome was suicide attempt at any follow-up. The DISC was used to assess psychiatric disorder diagnoses and attempted suicide and the Child Depression Inventory to assess depressive symptoms. Psychosocial and sociodemographic risk factors were also measured. Analyses used backward stepwise logistic regression modeling. RESULTS: At enrollment, 51% was female individuals, 49% Black, 40% Latinx, and 11% both Black and Latinx. Attempted suicide prevalence was significantly higher among AYALPHIV compared with AYAPHEU (27% vs 16%, P = 0.019), with AYALPHIV having 2.21 times the odds of making an attempt [95% confidence interval: (1.18 to 4.12), P = 0.013]. Higher Child Depression Inventory scores were associated with an increased risk of attempted suicide in both groups and the total sample. The presence of DISC-defined behavior disorder increased the risk of attempted suicide in the total sample and the AYALPHIV subgroup. Religiosity was protective of attempted suicide in AYALPHIV. CONCLUSIONS: AYALPHIV had increased suicide attempts compared with AYAPHEU. Religiosity was protective in AYALPHIV. Highlighting a need for prevention of early mental health challenges was associated with risk.

Psychotic symptoms in mass shootings v. mass murders not involving firearms: findings from the Columbia mass murder database.

BACKGROUND: Mass shootings account for a small fraction of annual worldwide murders, yet disproportionately affect society and influence policy. Evidence suggesting a link between mass shootings and severe mental illness (i.e. involving psychosis) is often misrepresented, generating stigma. Thus, the actual prevalence constitutes a key public health concern. METHODS: We examined global personal-cause mass murders from 1900 to 2019, amassed by review of 14 785 murders publicly described in English in print or online, and collected information regarding perpetrator, demographics, legal history, drug use and alcohol misuse, and history of symptoms of psychiatric or neurologic illness using standardized methods. We distinguished whether firearms were or were not used, and, if so, the type (non-automatic v. semi- or fully-automatic). RESULTS: We identified 1315 mass murders, 65% of which involved firearms. Lifetime psychotic symptoms were noted among 11% of perpetrators, consistent with previous reports, including 18% of mass murderers who did not use firearms and 8% of those who did (χ2 = 28.0, p < 0.01). US-based mass shooters were more likely to have legal histories, use recreational drugs or misuse alcohol, or have histories of non-psychotic psychiatric or neurologic symptoms. US-based mass shooters with symptoms of any psychiatric or neurologic illness more frequently used semi-or fully-automatic firearms. CONCLUSIONS: These results suggest that policies aimed at preventing mass shootings by focusing on serious mental illness, characterized by psychotic symptoms, may have limited impact. Policies such as those targeting firearm access, recreational drug use and alcohol misuse, legal history, and non-psychotic psychopathology might yield more substantial results.

Mortality risk among a sample of sexual minority women: A focus on the role of sexual identity disclosure.

Almost no research has examined factors that contribute to mortality risk among sexual minority women (SMW). This study capitalizes on a 21-year community-based longitudinal study of SMW to examine the association between sexual identity disclosure and mortality risk. Forty-nine SMW who were recruited in 2000-01 or 2010-12 (6.3% of the sample), were confirmed dead by 2019. The mean age at death was 56.5 years. We used Cox proportional hazard models to show that SMW who had disclosed their sexual identity to 100% of their immediate family members had a 70% reduction in the risk of mortality compared to SMW who disclosed to less than 33% of their immediate family, after adjusting for several sociodemographic and health variables. Our results suggest that facilitating acceptance of SMW and their ability to disclose their identity may be an important way to improve health and life expectancy among SMW.

Prevalence and minority-stress correlates of past 12-month prescription drug misuse in a national sample of transgender and gender nonbinary adults: Results from the U.S. Transgender Survey.

BACKGROUND: Prescription drug (PD) misuse, particularly opioid misuse, is a major US public health concern. While transgender and gender nonbinary (TGNB) individuals experience numerous health disparities, including substance use disparities, little research has focused on PD misuse in this population. METHODS: Data for this secondary analysis come from the US Transgender Survey (N = 26,689). First, we examined bivariate differences in past 12-month PD misuse among binary transgender women, binary transgender men, nonbinary individuals assigned-female-at-birth (AFAB), and nonbinary individuals assigned-male-at-birth (AMAB). We then used multivariable logistic regression (separately based on sex-assigned-at-birth) to examine the relationship between gender-identity related discrimination and PD misuse. RESULTS: PD misuse was significantly more common among binary transgender men (17.3 %), nonbinary AFAB individuals (18.7 %), and nonbinary AMAB individuals (18.0 %); compared to binary transgender women (13.5 %). In multivariable analyses, nonbinary identity was associated with higher odds of PD misuse among TGNB AFAB individuals (OR = 1.121; 95 %CI 1.021-1.232) and AMAB individuals (OR = 1.315; 95 % CI 1.133-1.527). Controlling for overall health status and psychological distress, public accommodations discrimination was associated with PD misuse among TGNB AMAB individuals (OR = 1.578, 95 %CI 1.354-1.839). Among both groups, healthcare discrimination was associated with PD misuse (AFAB OR = 1.388, 95 %CI 1.255-1.534; AMAB OR = 1.227, 95 %CI 1.073-1.404). CONCLUSION: In this national sample of TGNB individuals, nonbinary individuals were at greater risk for PD misuse than binary individuals, possibly due to less societal affirmation. Similar to other TGNB health disparities, discrimination based on gender identity/expression was associated with PD misuse. This highlights the importance of interventions to reduce discrimination against TGNB individuals.

Evaluation of an Innovative Curriculum Enhancement: The Conversation Project.

Two northeast nursing schools piloted an innovative curriculum to teach The Conversation Project (TCP) to the next generation of nurses. The goal was to educate 26 graduate nursing students about how to have end-of-life and advance care planning conversations with people before they experience a crisis. The focus of assignments was on communicating newly learned TCP information. Postreflections demonstrated that participants felt their communication skills had been enhanced while their anxieties were reduced. The students' abilities to have end-of-life conversations increased.

End-of-life nursing education: Enhancing nurse knowledge and attitudes.

AIM: To evaluate the effectiveness of a palliative and end-of-life care nursing education program on nurses' knowledge and attitudes toward caring for patients with advanced serious illness or nearing death. BACKGROUND: It is projected that 9 million Americans will be over 85 years old, in the year 2030; many will be living with disabilities and serious medical conditions. Expanding access to palliative care resources and knowledgeable providers is essential for meeting the future demands required by the aging population. METHODS: A quasi-experimental research design with pre-test and post-test measures was utilized. Potential sample included 134 nurses who participated in a 6-week, 12-hour End-of-Life Nursing Education Consortium (ELNEC) Core Curriculum© educational program. Changes in knowledge were measured using The Palliative Care Quiz for Nursing (PCQN) (n = 61), while changes in attitudes in caring for dying patients were measured using the Thanatophobia Scale (TS) (n = 57). RESULTS: Results suggest that while post-test PCQN knowledge scores increased significantly (t = -7.498; p = .000), practicing nurses were somewhat lacking in EOL care knowledge answering 13/20 questions correctly before, and 15/20 questions correctly after the educational intervention. Results also indicated that the sample had positive attitudes in caring for this patient population initially, but that attitudes improved significantly post-intervention (t = 3.944; p = .000). CONCLUSIONS: Results support the use of the ELNEC© curriculum for EOL education among this sample, suggesting that educating practicing nurses about EOL is an effective mechanism for both increasing knowledge and improving attitudes. Results also suggest that more education is warranted.

The potency of the broad spectrum bacteriocin, bactofencin A, against staphylococci is highly dependent on primary structure, N-terminal charge and disulphide formation.

Bactofencin A is a novel class IId bacteriocin, produced by the intestinal isolate Lactobacillus salivarius DPC6502, which has potent activity against medically significant pathogens including Staphylococcus aureus. This bacteriocin is unusual in that it has a highly cationic N terminus and a single disulfide bond between Cys7 and Cys22, resulting in a large C terminal loop. In this study, a library of synthetic bactofencin A variants were screened against the mastitis isolate, S. aureus DPC5246, to identify key residues responsible for activity. It was apparent that substituting either cysteine of the disulfide bond with either serine or alanine significantly reduced the activity of the bacteriocin, confirming the importance of the C terminal loop. Substituting N terminal amino acids with alanine had no effect on activity, whereas sequential removal of the N terminal positively charged residues resulted in an increasingly inactive peptide. A complete (synthetic) alanine scanning analysis revealed that the residues between Val9 and Gly17 were most affected by substitution suggesting that this area has a major influence on the potency of the bacteriocin. Substituting residues in the loop region between Cys7 and Cys22 for D-amino acid equivalents had a more detrimental effect on activity than L-alanine substitutions. Specifically Y10A, N11A, P15A and T16A are active at 4, 16, 1 and 16 µM respectively while their D equivalents were inactive at 1000 µM, the highest concentration tested. Ultimately, this study identifies the critical features in the primary structure of the bacteriocin which gives it such potent activity against pathogenic staphylococci.

Perinatal palliative care: Integration in a United States nurse midwifery education program.

Midwifery students with perinatal palliative care education develop a skillset to provide holistic midwifery care to women and families who are experiencing stillbirth or life-limiting fetal diagnoses. This paper presents a model of perinatal palliative care in a United States midwifery education program. By utilizing evidence based practices and national programs, perinatal palliative care can be threaded through midwifery curricula to achieve international standards of practice and competencies. Most importantly, enhancing perinatal palliative care education will better prepare future midwives for when a birth outcome is not what was expected at the outset of a pregnancy.

Describing clinical faculty experiences with patient safety and quality care in acute care settings: A mixed methods study.

BACKGROUND: A major safety initiative in acute care settings across the United States has been to transform hospitals into High Reliability Organizations. The initiative requires developing cognitive awareness, best practices, and infrastructure so that all healthcare providers including clinical faculty are accountable to deliver quality and safe care. OBJECTIVE: To describe the experience of baccalaureate clinical nursing faculty concerning safety and near miss events, in acute care hospital settings. METHODS: A mixed method approach was used to conduct the pilot study. Nurse faculty (n=18) completed study surveys from the Agency for Healthcare Research and Quality (AHRQ) to track patient safety concerns: Incidents; Near misses; or Unsafe conditions, during one academic semester, within 9 different acute care hospitals. Additionally, seven nurse faculty participated in end of the semester focus groups to discuss the semester long experience. RESULTS: Clinical faculty identified a total of 24 patient occurrences: 15 Incidents, 1 Near miss event, and 8 Unsafe conditions. Focus group participants (n=7) described benefits and challenges experienced by nursing clinical faculty and students in relation to the culture of safety in acute care hospital settings. Six themes resulted from the content analysis. CONCLUSIONS: Utilizing nursing clinical faculty and students may add significant value to promoting patient safety and the delivery of quality care, within acute care hospital settings.
