A Scoping Review on Adverse Childhood Experiences Studies Using Latent Class Analysis: Strengths and Challenges.

Adverse childhood experiences (ACEs) studies reveal the profound impacts of experiencing trauma and hardships in childhood. However, the cumulative risk approach of treating ACEs obscures the heterogeneity of ACEs and their consequences, making actionable interventions impossible. latent class analysis (LCA) has increasingly been used to address these concerns by identifying underlying subgroups of people who experience distinctive patterns of co-occurring ACEs. Though LCA has its strengths, the existing research produces few comparable findings because LCA results are dependent on ACEs measures and indicators, which vary widely by study. Therefore, a scoping review of ACEs studies using LCA that focuses on ACEs measures, indicators, and findings is needed to inform the field. Following Arksey and O'Malley's five-stage scoping review methodological framework, we first identified 211 articles from databases of EBSCOhost, PubMed, and Scopus using "adverse childhood experiences" for title search and "latent class analysis" for abstract search. Based on the inclusion criteria of peer-reviewed articles written in English published from 2012 to 2022 and the exclusion criteria of nonempirical studies and the LCA not analyzing ACEs, we finally selected 58 articles in this scoping review. Results showed LCA has been increasingly endorsed in the ACEs research community to examine the associations between ACEs and human health and well-being across culturally diverse populations. LCA overcame the limitations of the traditional methods by revealing specific ACEs clusters that exert potent effects on certain outcomes. However, the arbitrary nature of selecting ACEs indicators, measures, and the limited use of theory impedes the field from moving forward.

The Role of School and Community Involvement in the Psychosocial Health Outcomes of Black and Latinx LGBTQ Youth.

PURPOSE: Lesbian, gay, bisexual, transgender, and queer-identified (LGBTQ) youth of color face poorer psychosocial health outcomes than their non-LGBTQ peers. Research suggests school-based and community activities promote psychosocial health for LGBTQ youth, but study samples are predominantly White. This study tested whether school enrollment and seven community activities were associated with LGBTQ community connectedness, happiness, and health among Black and Latinx LGBTQ youth. METHODS: This study used a subsample of Black and Latinx LGBTQ adolescents and young adults (N = 472) from the Social Justice Sexuality project. Mean differences in study variables were examined across intersectional racial/gender identity categories. Multiple regression analyses assessed the association of school enrollment and community activities with psychosocial health outcomes, accounting for covariates. RESULTS: Social activities for LGBTQ people (ß = 0.19) and LGBTQ people of color (POC; ß = 0.15) were associated with greater LGBTQ connectedness. While moderate religious services attendance (ß = -0.13) was associated with lower LGBTQ connectedness, high attendance was associated with greater happiness (ß = 0.13) and health (ß = 0.12). Social activities for LGBTQ-POC (ß = 0.13) were also associated with better health. School enrollment was not significantly associated with any outcomes and Latinx transgender and diverse youth had the lowest happiness and health. DISCUSSION: Social activities for LGBTQ people and LGBTQ-POC may play a role in the social connectedness and health of Black and Latinx LGBTQ youth, while frequent religious service attendance may support health and happiness. Schools and faith institutions should ensure their institutions are welcoming to LGBTQ youth. Public health workers might facilitate the involvement and inclusion of LGBTQ youth, while policy should support funding for community activities.

Impact of withdrawal time on adenoma detection rate: results from a prospective multicenter trial.

BACKGROUND AND AIMS: Performing a high-quality colonoscopy is critical for optimizing the adenoma detection rate (ADR). Colonoscopy withdrawal time (a surrogate measure) of ≥6 minutes is recommended; however, a threshold of a high-quality withdrawal and its impact on ADR are not known. METHODS: We examined withdrawal time (excluding polyp resection and bowel cleaning time) of subjects undergoing screening and/or surveillance colonoscopy in a prospective, multicenter, randomized controlled trial. We examined the relationship of withdrawal time in 1-minute increments on ADR and reported odds ratio (OR) with 95% confidence intervals. Linear regression analysis was performed to assess the maximal inspection time threshold that impacts the ADR. RESULTS: A total of 1142 subjects (age, 62.3 ± 8.9 years; 80.5% men) underwent screening (45.9%) or surveillance (53.6%) colonoscopy. The screening group had a median withdrawal time of 9.0 minutes (interquartile range [IQR], 3.3) with an ADR of 49.6%, whereas the surveillance group had a median withdrawal time of 9.3 minutes (IQR, 4.3) with an ADR of 63.9%. ADR correspondingly increased for a withdrawal time of 6 minutes to 13 minutes, beyond which ADR did not increase (50.4% vs 76.6%, P < .01). For every 1-minute increase in withdrawal time, there was 6% higher odds of detecting an additional subject with an adenoma (OR, 1.06; 95% confidence interval, 1.02-1.10; P = .004). CONCLUSIONS: Results from this multicenter, randomized controlled trial underscore the importance of a high-quality examination and efforts required to achieve this with an incremental yield in ADR based on withdrawal time.

Adverse childhood experiences and child behavioral health trajectory from early childhood to adolescence: A latent class analysis.

BACKGROUND: Adverse childhood experiences (ACEs) profoundly influence child development. Different patterns of ACEs among boys and girls may be associated with different developmental trajectories. OBJECTIVE: This study aimed to identify patterns of ACEs at age three and tested the associations of these patterns with child behavioral health problems from age three to age fifteen. PARTICIPANTS AND SETTING: This study used data (N = 4898) from the Fragile Families Child Wellbeing Study. METHODS: First, this study conducted latent class analysis (LCA) across ten indicators of ACEs at age 3. LCA was conducted separately for boys and girls. Second, class membership was tested for associations with child internalizing symptoms and externalizing behaviors (ages three, five, nine, and fifteen years). RESULTS: LCA identified five classes of ACEs for girls: low ACEs, parental separation, financial difficulty, chaotic home, and child maltreatment. LCA for boys, however, identified a six-class solution, in which there was a physical abuse-only class, while also a sixth high ACEs class that included both physical and emotional abuse. Classes with the most ACEs often had the highest symptomology (internalizing symptoms ranging from 0.24 to 0.56; externalizing ranging from 0.36 to 1.00; ps < .05). However, differences in behavioral health were detected depending on the patterns of ACES. At ages nine and fifteen, the financial difficulty group also had high symptomatology (internalizing symptoms ranging from 0.23 to 0.43; externalizing from 0.23 to 0.46; ps < .05). CONCLUSIONS: Findings provide implications including the need to examine ACEs heterogeneity and address financial difficulty as a substantial ACE.

High-Definition Colonoscopy Compared With Cuff- and Cap-Assisted Colonoscopy: Results From a Multicenter, Prospective, Randomized Controlled Trial.

BACKGROUND AND AIMS: Mucosal exposure devices including distal attachments such as the cuff and cap have shown variable results in improving adenoma detection rate (ADR) compared with high-definition white light colonoscopy (HDWLE). METHODS: We performed a prospective, multicenter randomized controlled trial in patients undergoing screening or surveillance colonoscopy comparing HDWLE to 2 different types of distal attachments: cuff (CF) (Endocuff Vision) or cap (CP) (Reveal). The primary outcome was ADR. Secondary outcomes included adenomas per colonoscopy, advanced adenoma and sessile serrated lesion detection rate, right-sided ADR, withdrawal time, and adverse events. Continuous variables were compared using Student's t test and categorical variables were compared using chi-square or Fisher's exact test using statistical software Stata version16. A P value <.05 was considered significant. RESULTS: A total of 1203 subjects were randomized to either HDWLE (n = 384; mean 62 years of age; 81.3% males), CF (n = 379; mean 62.7 years of age; 79.9% males) or CP (n = 379; mean age 62.1 years of age; 80.5% males). No significant differences were found among 3 groups for ADR (57.3%, 59.1%, and 55.7%; P = .6), adenomas per colonoscopy (1.4 ± 1.9, 1.6 ± 2.4, and 1.4 ± 2; P = .3), advanced adenoma (7.6%, 9.2%, and 8.2%; P = .7), sessile serrated lesion (6.8%, 6.3%, and 5.5%; P = .8), or right ADR (48.2%, 49.3%, and 46.2%; P = .7). The number of polyps per colonoscopy were significantly higher in the CF group compared with HDWLE and CP group (2.7 ± 3.4, 2.3 ± 2.5, and 2.2 ± 2.3; P = .013). In a multivariable model, after adjusting for age, sex, body mass index, withdrawal time, and Boston Bowel Preparation Scale score, there was no impact of device type on the primary outcome of ADR (P = .77). In screening patients, CF resulted in more neoplasms per colonoscopy (CF: 1.7 ± 2.6, HDWLE: 1.3 ± 1.7, and CP: 1.2 ± 1.8; P = .047) with a shorter withdrawal time. CONCLUSIONS: Results from this multicenter randomized controlled trial do not show any significant benefit of using either distal attachment devices (CF or CP) over HDWLE, at least in high-detector endoscopists. The Endocuff may have an advantage in the screening population. (ClinicalTrials.gov, Number: NCT03952611).

Disclosure of Sexual Identities Across Social-Relational Contexts: Findings from a National Sample of Black Sexual Minority Men.

Black sexual minority men (BSMM) in the USA navigate a range of factors that may influence the extent to which they disclose or conceal their sexual identity in various social contexts. To date, few studies have investigated the correlates of sexual identity disclosure or concealment among BSMM across multiple life domains. Guided by a minority stress perspective and intersectionality, we analyzed data from N = 809 BSMM who participated in the Social Justice Sexuality Survey. We conducted ordinary least squares regression to examine the relative weight of perceptions of homophobia, religiosity, LGBT community connectedness, racial identity salience, and sexual identity salience on disclosure of sexual identity in six social-relational contexts: (1) family, (2) friends, (3) neighbors, (4) religious community, (5) work, and (6) online. Findings indicate that BSMM disclosed their sexual identity unevenly across social-relational contexts. Notably, LGBTQ community connectedness and sexual identity importance were consistent predictors of sexual identity disclosure across contexts. In contrast, perceptions of homophobia were not related to sexual identity disclosure, suggesting that other factors may be more salient for BSMM when deciding to disclose their sexual identity. Finally, bisexual men consistently reported lower levels of sexual identity disclosure relative to gay men in all six contexts. Study findings have important implications for future research on sexual identity disclosure with diverse samples of BSMM.

Fecal microbiota transplantation and its potential therapeutic uses in gastrointestinal disorders.

Typical human gut flora has been well characterized in previous studies and has been noted to have significant differences when compared with the typical microbiome of various disease states involving the gastrointestinal tract. Such diseases include Clostridium difficile colitis, inflammatory bowel disease, functional bowel syndromes, and various states of liver disease. A growing number of studies have investigated the use of a fecal microbiota transplant as a potential therapy for these disease states.

Coffee: The magical bean for liver diseases.

Coffee has long been recognized as having hepatoprotective properties, however, the extent of any beneficial effect is still being elucidated. Coffee appears to reduce risk of hepatocellular carcinoma, reduce advancement of fibrotic disease in a variety of chronic liver diseases, and perhaps reduce ability of hepatitis C virus to replicate. This review aims to catalog the evidence for coffee as universally beneficial across a spectrum of chronic liver diseases, as well as spotlight opportunities for future investigation into coffee and liver disease.

Hepatocyte transplantation: Consider infusion before incision.

Human hepatocyte transplantation is undergoing study as a bridge, or even alternative, to orthotopic liver transplantation (OLT). This technique has undergone multiple developments over the past thirty years in terms of mode of delivery, source and preparation of cell cultures, monitoring of graft function, and use of immunosuppression. Further refinements and improvements in these techniques will likely allow improved graft survival and function, granting patients higher yield from this technique and potentially significantly delaying need for OLT.

Microbiome alterations observed in liver diseases present opportunities for potential fecal transplantation.

Many disease processes lead to chronic liver disease, however, progress has been made regarding common findings amongst these disease processes that may suggest a path forward for treatment. In particular, common alterations in the intestinal microflora of patients with different etiologies of liver disease may provide a clue as to the pathogenesis of these disorders as well a potential therapy. Data is still scant at this point, however, what is available suggests a promising opportunity for future studies to expand upon what has been demonstrated.

Effects of Victimization and Violence on Suicidal Ideation and Behaviors Among Sexual Minority and Heterosexual Adolescents.

PURPOSE: Sexual minority youth (SMY) are at higher risk for victimization and suicide than are heterosexual youth (HY). Relatively little research has examined which types of victimization are most closely linked to suicide, which is necessary to develop targeted prevention interventions. The present study was conducted to address this deficit. METHODS: The data come from the 2011 Chicago Youth Risk Behavior Survey (n = 1,907). Structural equation modeling (SEM) in Mplus evaluated the direct, indirect, and total effects of sexual orientation on a latent indicator of suicidal ideation and behaviors via seven types of victimization. Four indicators of victimization were school-specific (e.g., harassment due to sexual orientation or gender identity (SO/GID), bullying, threatened or injured with a weapon, and skipping school due to safety concerns), and three indicators assessed other types of victimization (e.g., electronic bullying, intimate partner violence, and sexual abuse). RESULTS: Thirteen percent of youth were classified as SMY. Significantly more SMY than HY reported suicidal ideation (27.95% vs. 13.64%), a suicide plan (22.78% vs. 12.36%), and at least one suicide attempt (29.92% vs. 12.43%) in the past year (all P < .001). A greater percentage of SMY reported SO/GID-related harassment, skipping school, electronic bullying, and sexual abuse. Sexual orientation was not directly related to suicidal ideation and behaviors in SEM. Rather, SMY's elevated risk of suicidality functioned indirectly through two forms of school-based victimization: being threatened or injured with a weapon (B = .19, SE = .09, P ≤ .05) and experiencing SO/GID-specific harassment (B = .40, SE = .15, P ≤ .01). There also was a trend for SMY to skip school as a strategy to reduce suicide risk. CONCLUSION: Although SMY experience higher rates of victimization than do HY, school-based victimization that involves weapons or is due to one's SO/GID appear to be the most deleterious. That SMY may skip school to reduce their risk of suicidal ideation and behaviors is problematic, and schools should be encouraged to enact and enforce policies that explicitly protect SMY from victimization.

Serum folate receptor alpha, mesothelin and megakaryocyte potentiating factor in ovarian cancer: association to disease stage and grade and comparison to CA125 and HE4.

BACKGROUND: Evaluate and compare the utility of serum folate receptor alpha (FRA) and megakaryocyte potentiating factor (MPF) determinations relative to serum CA125, mesothelin (MSLN) and HE4 for the diagnosis of epithelial ovarian cancer (EOC). METHODS: Electrochemiluminescent assays were developed for FRA, MSLN and MPF and used to assess the levels of these biomarkers in 258 serum samples from ovarian cancer patients. Commercial assays for CA125 and HE4 were run on a subset of 176 of these samples representing the serous histology. Data was analyzed by histotype, stage and grade of disease. A comparison of the levels of the FRA, MSLN and MPF biomarkers in serum, plasma and urine was also performed in a subset of 57 patients. RESULTS: Serum and plasma levels of FRA, MSLN and MPF were shown to be highly correlated between the two matrices. Correlations between all pairs of markers in 318 serum samples were calculated and demonstrated the highest correlation between HE4 and MPF, and the lowest between FRA and MPF. Serum levels of all markers showed a dependence on both stage and grade of disease. A multi-marker logistic regression model was developed resulting in an AUC=0.91 for diagnosis of serous ovarian cancer, a significant improvement over the AUC for any of the individual markers, including CA125 (AUC=0.84). CONCLUSIONS: FRA has significant potential as a biomarker for ovarian cancer, both as a stand-alone marker and in combination with other known markers for EOC. The lack of correlation between the various markers analyzed in the present study suggests that a panel of markers can aid in the detection and/or monitoring of this disease.

Inter-alpha inhibitor protein administration improves survival from neonatal sepsis in mice.

Inter-alpha inhibitor proteins (IaIp) are serine proteases inhibitors that modulate endogenous protease activity and have been shown to improve survival in adult models of sepsis. We evaluated the effect of IaIp on survival and systemic responses to sepsis in neonatal mice. Sepsis was induced in 2-d-old mice with lipopolysaccharide (LPS), Escherichia coli, and group B Streptococci. Sepsis was associated with 75% mortality. IaIp, given by i.p. administration at doses between 15 and 45 mg/kg from 1 to 6 h after the onset of sepsis, improved survival to approximately 90% (p = 0.0159) in both LPS-induced sepsis and with live bacterial infections. The greatest effect was on reversal of hemorrhagic pneumonitis. The effects were dose and time dependent. Systemic cytokine profile and tissue histology were examined. Survival was compared in IL-10 knock out animals. Systemic cytokine levels including TNF-[alpha] and IL-10 were increased after induction of sepsis and modulated significantly after IaIp administration. Because the effect of IaIp was still demonstrable in IL-10 deficient mice, we conclude the beneficial effects of IaIp is because of suppression of proinflammatory cytokines such as TNF-[alpha] rather than augmentation of IL-10. IaIp may offer significant benefits as a therapeutic
