RESUMEN
Oral microbiota is vital for human health and can be affected by various factors (i.e. diets, ethnicity). However, few studies have compared oral microbiota of individuals from different nationalities in the same environment. Here, we explored the assembly and interaction of oral microbial communities of Chinese and Pakistanis in one university. Firmicutes and Proteobacteria were the predominant microorganisms in the oral cavity of Chinese and Pakistanis. Streptococcus and Neisseria were the dominant genera of China, while Streptococcus and Haemophilus were the dominant genera of Pakistanis. In addition, the oral community membership and structure were not influenced by season, Chinese/Pakistani student and gender, reflecting the stability of the human oral microbiome. The beta diversity of oral microbiomes between Chinese and Pakistanis significantly differed in winter, but not in spring. The alpha diversity of Chinese students and Pakistani students was similar. Moreover, oral microbial community of both Chinese and Pakistani students was mainly driven by stochastic processes. The microbial network of Chinese was more complexity and stability than that of Pakistanis. Our study uncovers the characteristics of human oral microbiota, which is of great significance for oral and human health.

OBJECTIVES: Our study aimed to identify how emergency department (ED) arrival rate, process of care, and physical layout can impact ED length of stay (LOS) in pediatric traumatic brain injury care. METHODS: Process flows and value stream maps were developed for 3 level I pediatric trauma centers. Computer simulation models were also used to examine "what if" scenarios based on ED arrival rates. RESULTS: Differences were observed in prearrival preparation time, ED physical layouts, and time spent on processes. Shorter prearrival preparation time, trauma bed location far from diagnostic or treatment areas, and ED arrival rates that exceed 20 patients/day prolonged ED LOS. This was particularly apparent in 1 center where computer simulation showed that relocation of trauma beds can reduce ED LOS regardless of the number of patients that arrive per day. CONCLUSIONS: Exceeding certain threshold ED arrival rates of children with traumatic brain injury can substantially increase pediatric trauma center ED LOS but modifications to ED processes and bed location may mitigate this increase.

The aspariginyl hydroxylase human factor inhibiting hypoxia-inducible factor (FIH) is an important regulator of the transcriptional activity of hypoxia-inducible factor. FIH also catalyzes the hydroxylation of asparaginyl and other residues in ankyrin repeat domain-containing proteins, including apoptosis stimulating of p53 protein (ASPP) family members. ASPP2 is reported to undergo a single FIH-catalyzed hydroxylation at Asn-986. We report biochemical and crystallographic evidence showing that FIH catalyzes the unprecedented post-translational hydroxylation of both asparaginyl residues in "VNVN" and related motifs of ankyrin repeat domains in ASPPs (i.e., ASPP1, ASPP2, and iASPP) and the related ASB11 and p18-INK4C proteins. Our biochemical results extend the substrate scope of FIH catalysis and may have implications for its biological roles, including in the hypoxic response and ASPP family function.

Sexual risk behaviors often co-occur. Understanding the heterogeneity in patterns of sexual behavior among youth and how context of majority and minoritized status may be related to these behaviors can inform targeted STIs/HIV interventions. Data are from the Boricua Youth Study, a longitudinal study of two probability samples of Puerto Rican youth recruited in the South Bronx (SBx) and the metropolitan area in Puerto Rico (PR). We identified patterns of sexual behaviors among young adults (ages 15-24) with sexual experience (N = 1,203) using latent class analysis. Analyses examined context differences and the prospective relationship between adverse childhood experiences (ACEs) (childhood maltreatment/violence, family/parental dysfunction) and patterns of sexual behaviors (age at first sex, number of sex partners, sex with a high-risk partner, condom use, sex while intoxicated, oral sex, anal sex). We identified five classes of sexual behaviors: (1) currently inactive (16.51%); (2) single partner, low activity (13.49%); (3) single partner, inconsistent condom use (32.19%); (4) single partner, sex without a condom (27.65%); and (5) multirisk (10.16%). Young adults from the SBx (minoritized context), those who identified as male, and those with higher child maltreatment/violence ACEs were more likely to be in the multi-risk class relative to the single partner, inconsistent condom use class. Those from the SBx were also more likely to be in the single partner, sex without condom class, relative to the single partner, inconsistent condom use class. Differences in young adults' patterns of sexual behaviors between the two contexts, one representing the minoritized context (SBx) contrasted to the majority context (PR), were not explained by ACEs. Findings highlight the heterogeneity in the patterns of sexual behaviors among Puerto Rican young adults as well as how such patterns vary based on sociocultural contexts. Exposure to child maltreatment/violence ACEs was related to the riskier patterns; however, they did not explain why riskier patterns of sexual behaviors were found in the SBx compared to PR. Results underscore the need for tailored interventions and more in-depth examination of differences across contexts.

Untangling assembly and microbial interaction of abundant and rare microbiota in aquatic ecosystem is pivotal for understanding how community assembly respond to environmental variables and co-occurrence patterns. Here, we explored the assembly mechanisms, their drivers, and species co-occurrence of abundant and rare microbiomes in the Yellow River using 16S rRNA gene sequencing in Lanzhou, China. Here, abundant community was ubiquitous across all sites, whereas rare community was uneven distributed. The richness and community dissimilarity of rare taxa were significantly greater than those of abundant ones. Stochastic processes structured the rare community assembly in spring and winter, while deterministic processes shaped the abundant and rare community assembly in other seasons and all sites. Copper and water temperature mediated the balance between deterministic and stochastic processes of abundant and rare community, respectively. A few abundant taxa with closer relationships frequently occupied central positions and had a great effect on other co-occurrences in the network, while the majority of keystone microbiota were rare microbiome and played a considerable part in maintaining the network structure. Our study provides some ecological proposals for water quality management and ecological stability of the Yellow River. KEY POINTS: ⢠Deterministic process dominated abundant and rare community assembly. ⢠Cu and TW mediated the balance of abundant and rare community assembly respectively. ⢠Abundant taxa had a greater effect on other co-occurrences in the network.

OBJECTIVES: Intergenerational transmission of trauma occurs when the effects of childhood maltreatment (CM) influence the next generation's development and health; prenatal programming via maternal mood symptoms is a potential pathway. CM is a risk factor for bipolar disorder which is present in 1.8% of pregnant women. Mood symptoms are likely to increase during pregnancy, particularly for those with a history of CM. We examined whether there was evidence for intergenerational transmission of trauma in utero in this population, and whether maternal mood was a transmission pathway. METHODS: CM and maternal mood were self-reported by N = 82 pregnant women in treatment for bipolar disorder. Fetal heart rate variability (FHRV) was measured at 24, 30, and 36 weeks' gestation. Gestational age at birth and birth weight were obtained from medical charts. RESULTS: A cluster analysis yielded two groups, Symptom+ (18.29%) and Euthymic (81.71%), who differed on severe mood symptoms (p < 0.001) but not on medication use. The Symptom+ group had more CM exposures (p < 0.001), a trend of lower FHRV (p = 0.077), and greater birth complications (33.3% vs. 6.07% born preterm p < 0.01). Maternal prenatal mood mediated the association between maternal CM and birth weight in both sexes and at trend level for gestational age at birth in females. CONCLUSIONS: This is the first study to identify intergenerational effects of maternal CM prior to postnatal influences in a sample of pregnant women with bipolar disorder. These findings underscore the potential enduring impact of CM for women with severe psychiatric illness and their children.

Efficient stop codon recognition and peptidyl-tRNA hydrolysis are essential in order to terminate translational elongation and maintain protein sequence fidelity. Eukaryotic translational termination is mediated by a release factor complex that includes eukaryotic release factor 1 (eRF1) and eRF3. The N terminus of eRF1 contains highly conserved sequence motifs that couple stop codon recognition at the ribosomal A site to peptidyl-tRNA hydrolysis. We reveal that Jumonji domain-containing 4 (Jmjd4), a 2-oxoglutarate- and Fe(II)-dependent oxygenase, catalyzes carbon 4 (C4) lysyl hydroxylation of eRF1. This posttranslational modification takes place at an invariant lysine within the eRF1 NIKS motif and is required for optimal translational termination efficiency. These findings further highlight the role of 2-oxoglutarate/Fe(II) oxygenases in fundamental cellular processes and provide additional evidence that ensuring fidelity of protein translation is a major role of hydroxylation.

Maternal prenatal stress influences offspring neurodevelopment and birth outcomes including the ratio of males to females born; however, there is limited understanding of what types of stress matter, and for whom. Using a data-driven approach with 27 variables from questionnaires, ambulatory diaries, and physical assessments collected early in the singleton pregnancies of 187 women, 3 latent profiles of maternal prenatal stress emerged that were differentially associated with sex at birth, birth outcomes, and fetal neurodevelopment. Most women (66.8%) were in the healthy group (HG); 17.1% were in the psychologically stressed group (PSYG), evidencing clinically meaningful elevations in perceived stress, depression, and anxiety; and 16% were in the physically stressed group (PHSG) with relatively higher ambulatory blood pressure and increased caloric intake. The population normative male:female secondary sex ratio (105:100) was lower in the PSYG (2:3) and PHSG (4:9), and higher in the HG (23:18), consistent with research showing diminished male births in maternal stress contexts. PHSG versus HG infants were born 1.5 wk earlier (P < 0.05) with 22% compared to 5% born preterm. PHSG versus HG fetuses had decreased fetal heart rate-movement coupling (P < 0.05), which may indicate slower central nervous system development, and PSYG versus PHSG fetuses had more birth complications, consistent with previous findings among offspring of women with psychiatric illness. Social support most strongly differentiated the HG, PSYG, and PHSG groups, and higher social support was associated with increased odds of male versus female births. Stress phenotypes in pregnant women are associated with male vulnerability and poor fetal outcomes.

Inflammatory processes are a candidate mechanism by which early adversity may be biologically embedded and subsequently lead to poorer health outcomes; in pregnancy, this has been posited as a pathway for intergenerational transmission of adversity. Studies in non-pregnant adults suggest that factors such as mood, diet, BMI, and social support may moderate associations between childhood trauma history and inflammation in adulthood, though few studies have examined these associations among pregnant women. In a sample of healthy pregnant women (N = 187), we analyzed associations between maternal childhood adversity, including maltreatment and non-optimal caregiving experiences, with circulating Interleukin-6 (IL-6) levels during trimesters 2 (T2) and 3 (T3) of pregnancy. We also assessed whether these associations were moderated by psychosocial and lifestyle factors including depressive symptoms, social support, physical activity, and diet quality. History of childhood maltreatment was not associated with IL-6 in either T2 or T3 of pregnancy, either independently or in interaction with depressive symptom severity. However, in there was a significant positive association between childhood maltreatment and IL-6 in Trimester 2 in the context of poorer diet quality (p = 0.01), even after adjusting for BMI. Additionally, the quality of caregiving women received in childhood was associated with levels of IL-6 in Trimester 3, but only via interaction with concurrent depressive symptoms (p = 0.02). These findings provide evidence that for those with a history of childhood adversity, levels of inflammatory cytokines in pregnancy may be more sensitive to depressive symptoms and diet quality.

Motor vehicle crashes are a global public health concern. Most analysis have used zero-inflated count models for examining crash counts. However, few methods are available to account for safety metrics that have semi-continuous observations. This article considers the problem of variable selection for the semi-continuous zero-inflated (SCZI) models. These models include two parts: a zero-inflated part and a nonzero continuous part. A special group regularization is designed to accommodate the unique structure of two-part SCZI models, and a type of Bayesian information criterion is proposed to select tuning parameters. We illustrate the variable selection process of the proposed model using lane position data from a driving simulator study. In the study, drivers stay in the intended lane for the majority of their drive (zero-inflated part). On occasion, some drivers do drift out of their intended driving lane (nonzero continuous part). Our findings show that individual differences can be captured with the proposed model, which has implications for driving safety and the design of in-vehicle alerting systems.

Skin microbiomes function directly in human health and are affected by various external and internal factors. However, few studies have showed the variation of human skin microbiota at multiple body sites in individuals of different national origin living in the same environment. Here, using 16S rRNA sequencing, we investigated the diversity and function of skin microbiomes in different body locations of Chinese and Pakistani individuals from a single college in China. Body location and nationality significantly affected community structures, while season and gender only impacted community member. Due to different lifestyles and likely genetic characteristics of the hosts, Proteobacteria was more abundant in Pakistanis than in Chinese individuals. There were significant differences in the Shannon diversity of skin microorganisms among different skin sites of Chinese individuals, but not in Pakistanis. PICRUSt prediction indicated that gene functions involved in carbohydrate metabolism, lipid metabolism, and xenobiotics biodegradation and metabolism were higher in bacteria collected from Pakistanis than those from Chinese individuals, but the amino acid metabolism of skin microorganisms in Chinese people was higher. The relative abundances of potential pathogenic bacteria also differed in different body locations, providing a foundation for studying skin-associated bacterial diseases. Through a meta-analysis of 233 human skin samples from eight elevational sites in western China, we found that skin microbial diversity first decreased and then increased with increasing altitude. Network analysis showed positive correlation between altitude and Lactobacillus, Chryseobacterium, or Acinetobacter. Our results uncover the variation of human skin microbiota allowing future explorations of potential significance for human health. KEY POINTS: ⢠Body location and nationality affect skin microbiota diversity and function. ⢠Proteobacteria was more abundant in Pakistanis than in Chinese. ⢠Skin microbial diversity first decreased and then increased with elevated altitude.

BACKGROUND: Maternal prenatal stress is associated with worse socio-emotional outcomes in offspring throughout childhood. However, the association between prenatal stress and later caregiving sensitivity is not well understood, despite the significant role that caregiving quality plays in child socio-emotional development. The goal of this study was to examine whether dimensions of pregnancy-specific stress are correlated with observer-based postnatal maternal caregiving sensitivity in pregnant adolescents. METHODS: Healthy, nulliparous pregnant adolescents (n = 244; 90 % LatinX) reported on their pregnancy-specific stress using the Revised Prenatal Distress Questionnaire (NuPDQ). Of these 244, 71 participated in a follow-up visit at 14 months postpartum. Videotaped observations of mother-child free play interactions at 14 months postpartum were coded for maternal warmth and contingent responsiveness. Confirmatory factor analysis of the NuPDQ supported a three-factor model of pregnancy-specific stress, with factors including stress about the social and economic context, baby's health, and physical symptoms of pregnancy. RESULTS: Greater pregnancy-specific stress about social and economic context and physical symptoms of pregnancy was associated with reduced maternal warmth but not contingent responsiveness. CONCLUSIONS: Heightened maternal stress about the social and economic context of the perinatal period and physical symptoms of pregnancy may already signal future difficulties in caregiving and provide an optimal opening for early parenting interventions.

Pregnancy is a critical time for the effects of environmental factors on children's development. The effect of added sugar intake on fetal development and pregnancy outcomes remains understudied despite increasing dietary intake in the United States. This study investigated the effect of added sugar on fetal programming by examining the association between maternal added sugar consumption, fetal movement, birth outcomes, and placental DNA methylation. Further, primary human fibroblasts were cultured under normal or high glucose conditions to assess the effect of high glucose exposure on cells' DNA methylation. We found that higher added sugar intake across pregnancy was associated with reduced 3rd-trimester fetal movement (p < .05) and shorter gestation (p < .01). Our sample size was not powered to detect the alteration of individual placental CpG with genome-wide significance. However, a secondary analysis suggested that added sugar consumption was associated with differential methylation of functionally related gene families across pregnancy. Consistent with this, high glucose exposure in primary cultured human fibroblasts altered the methylation of 17% of all CpGs, providing converging evidence for an effect of sugar on DNA methylation. Our results suggest that diets high in added sugar during pregnancy may have implications for offspring health via prenatal programming effects measurable before birth.

OBJECTIVE: There are concerns regarding the potential harms in receipt of prenatal chromosome microarray (CMA) results, particularly variants of uncertain significance (VUS). We examined the influence that the return of genomic results had on parental well-being and perceptions of children's development. METHODS: Parents (n = 138) of 83 children who underwent prenatal chromosomal microarray testing completed questionnaires assessing perception of children's development, parent-child attachment, parental mood, parenting competence, martial satisfaction, satisfaction with the decision to undergo testing, and attitudes about genetics at age 12 and/or 36 months. Responses were compared between parents who received normal/likely benign results and VUS results. RESULTS: Compared to normal/likely benign results, parents who received VUS results rated their child as less competent on the BITSEA scale at 12 (ß = -1.65, P = .04) though not 36 months (P = .43). There were no differences in parent mood, marital satisfaction, or parenting competence. At 36 months, parents in the VUS group reported less satisfaction with their decision to undergo genetic testing (ß = 1.51, P = .02). CONCLUSION: Chromosome microarray VUS results have limited impact on parental well-being and perception of children's development. However, the initial diminished perception of child competency and later dissatisfaction with genomic testing indicate the need to assist parents in coping with ambiguous results.

Psychotropic medication use and psychiatric symptoms during pregnancy each are associated with adverse neurodevelopmental outcomes in offspring. Commonly, studies considering medication effects do not adequately assess symptoms, nor evaluate children when the effects are believed to occur, the fetal period. This study examined maternal serotonin reuptake inhibitor and polypharmacy use in relation to serial assessments of five indices of fetal neurobehavior and Bayley Scales of Infant Development at 12 months in N = 161 socioeconomically advantaged, non-Hispanic White women with a shared risk phenotype, diagnosed major depressive disorder. On average fetuses showed the expected development over gestation. In contrast, infant average Bayley psychomotor and mental development scores were low (M = 84.10 and M = 89.92, range of normal limits 85-114) with rates of delay more than 2-3 times what would be expected based on this measure's normative data. Controlling for prenatal and postnatal depressive symptoms, prenatal medication effects on neurobehavioral development were largely undetected in the fetus and infant. Mental health care directed primarily at symptoms may not address the additional psychosocial needs of women parenting infants. Speculatively, prenatal serotonin reuptake inhibitor exposure may act as a plasticity rather than risk factor, potentially enhancing receptivity to a nonoptimal postnatal environment in some mother-infant dyads.

OBJECTIVE: Limited data exist on child abuse-related immune variation during pregnancy, despite implications for maternal and infant health and extensive data showing that abuse history and depression are related to increased inflammation in other populations. This study examined associations among child abuse, depression, circulating levels of inflammatory markers, and perinatal health in pregnant adolescents, a group at high risk for childhood abuse and poor birth outcomes. METHODS: Pregnant teenagers (n = 133; 14-19 years; 89.5% Latina) reported on abuse and depression and had two blood draws (24-27 and 34-37 gestational weeks, second and third trimesters, respectively) for interleukin-6 (IL-6) and C-reactive protein; birth outcomes were collected. RESULTS: Abuse and depression interacted to predict higher IL-6 at second trimester (B = 0.006, p = .011) such that severely abused adolescents with high depression had higher IL-6 relative to severely abused adolescents with low depression; depression did not differentiate IL-6 levels for those with low abuse severity. Abuse and IL-6 also interacted to predict gestational age at birth (B = 0.004, p = .040) such that those with low abuse and high IL-6 and those with high abuse and low IL-6 had infants with earlier gestational age at birth. Cortisol at the second trimester mediated the association between IL-6 and gestational age at birth (indirect effect estimate=-0.143, p < .039). CONCLUSIONS: Depression severity distinguished IL-6 levels among more severely abused pregnant Latina adolescents, but it was unrelated to IL-6 among less severely abused adolescents. Cortisol explained the relationship between IL-6 and earlier gestational age at birth. Multiple adversities and inflammation may influence birth outcomes and potentially affect intergenerational health.

BACKGROUND: Heavy alcohol consumption can be harmful, particularly for individuals with HIV. There is substantial variability in response to interventions that aim to reduce drinking. Neighborhood drinking norms may explain some of this variability among HIV-infected patients. Therefore, we investigated whether neighborhood-level drinking norms modified response to alcohol intervention among HIV-infected heavy drinkers. METHODS: Heavily-drinking HIV comprehensive care patients (n = 230) completed 1 of 3 brief alcohol interventions (an educational intervention, a motivational interviewing [MI] intervention, or an MI intervention with a technological enhancement called HealthCall). Drinking was reported at baseline and end of treatment (60 days). Neighborhood-level drinking norms were obtained from a separate general population study. RESULTS: Patients' reductions in drinks per drinking day in response to MI (as compared with the educational control) were more pronounced in neighborhoods with more permissive drinking norms. In contrast, patients' reductions in drinks per drinking day in response to MI plus HealthCall did not significantly vary between neighborhoods with different drinking norms. Norms did not evidence significant interactions with intervention condition for 3 other exploratory drinking outcomes (drinking frequency, binge frequency, and maximum quantity). CONCLUSIONS: Neighborhood-level drinking norms help explain differential response to an alcohol MI intervention among HIV-infected patients. This study suggests the utility of considering neighborhood context as an effect modifier of alcohol interventions.

Most interventions to prevent postpartum depression (PPD) focus on the mother rather than the mother-infant dyad. As strong relationships between infant sleep and cry behavior and maternal postpartum mood have been demonstrated by previous research, interventions targeted at the dyad may reduce symptoms of PPD. The goal of the current study was to examine the effectiveness of Practical Resources for Effective Postpartum Parenting (PREPP). PREPP is a new PPD prevention protocol that aims to treat women at risk for PPD by promoting maternally mediated behavioral changes in their infants, while also including mother-focused skills. Results of this randomized control trial (RCT) (n = 54) indicate that this novel, brief intervention was well tolerated and effective in reducing maternal symptoms of anxiety and depression, particularly at 6 weeks postpartum. Additionally, this study found that infants of mothers enrolled in PREPP had fewer bouts of fussing and crying at 6 weeks postpartum than those infants whose mothers were in the Enhanced TAU group. These preliminary results indicate that PREPP has the potential to reduce the incidence of PPD in women at risk and to directly impact the developing mother-child relationship, the mother's view of her child, and child outcomes.

BACKGROUND: Helping alcohol-dependent individuals to cope with, or regulate, cue-induced craving using cognitive strategies is a therapeutic goal of cognitive behavioral therapy (CBT) for alcohol dependence. An assumption that underlies this approach is that alcohol dependence is associated with deficits in such cognitive regulation abilities. To date, however, the ability to utilize such strategies for regulation of craving has never been tested in a laboratory setting. METHODS: Here we compared 19 non-treatment-seeking, alcohol-dependent drinkers (AD) to 21 social drinkers (SD), using a laboratory task that measured the ability to reduce cue-induced alcohol craving by thinking about long-term negative consequences of drinking, which is a specific cognitive regulation strategy that is taught in CBT. The task also assessed the ability to reduce food craving elicited by high-calorie food cues using a similar strategy. RESULTS: The reduction in craving when using this cognitive regulation strategy was approximately double in SD, compared to AD, for both alcohol and food cues. Furthermore, in SD but not AD, the ability to regulate cue-induced alcohol craving was correlated with the ability to regulate food craving. There were no significant correlations found between the ability to regulate cue-induced alcohol craving and a number of self-report measures related to severity of alcohol dependence, baseline craving, impulsivity, and general self-regulation ability, for either AD or SD. CONCLUSIONS: The results suggest that alcohol dependence is associated with deficits in cognitive regulation of cue-induced craving and that these deficits are not specific to the regulation of alcohol craving, but generalize to the regulation of other appetitive states, such as food craving. Future studies may use similar procedures to address the neural and cognitive processes that underlie such regulation deficits, as well as the effects of treatments such as CBT on these processes.
