Global stress and daily general and type 1 diabetes stressors and links to daily affect and diabetes outcomes during emerging adulthood.

We examined how global stress and general stressors of daily life relate to emotional well-being and type 1 diabetes (T1D) outcomes and amplify the effects of diabetes stressors in emerging adults. Two-hundred and seven 18-19-year-olds with T1D (duration 8.47 years) completed the Perceived Stress Scale (global stress) and a daily diary assessing daily diabetes and general stressors, positive and negative affect, self-care behaviors, and blood glucose (BG). Multi-level analyses indicated that global stress and within-person daily general and diabetes stressors were associated with more negative and less positive affect. In addition, general stress (between-person) was associated with more negative affect. Global stress amplified the association between daily diabetes stressors and negative affect, with greater affect reactivity to stress for those experiencing higher global stress. Global stress and both within- and between-person diabetes stressors were associated with lower self-care and higher BG. Emerging adults' general stressors in their daily lives relate to poorer well-being beyond the experience of diabetes stressors.

Acceptability and Feasibility of FAMS-T1D mHealth intervention to optimize self- & social regulation for emerging adults with type 1 diabetes.

Background: Among emerging adults with type 1 diabetes (T1D), self-regulation and social regulation skills can help avoid high A1c and diabetes distress. FAMS (Family/friend Activation to Motivate Self-care) is mobile phone-delivered intervention that supports development of these skills and is efficacious among adults with type 2 diabetes. However, the acceptability and feasibility of the FAMS intervention among emerging adults with T1D is unknown. Methods: Therefore, we adapted FAMS for in a new disease context and developmental stage then conducted a 3-month mixed-methods pre-post pilot study. Participants were emerging adults with T1D and a friend/family member enrolled as a support person (optional). Feasibility/acceptability outcomes and associated progression thresholds were recruitment (≥ 70% eligible emerging adults), retention (≥ 85%), intervention engagement (≥ 70%) and satisfaction (≥ 70%). We also collected qualitative feedback to determine if the intervention addressed relevant needs and explored changes in outcomes of interest (family/friend involvement, self-efficacy, self-management, distress, A1c). Results: Recruitment rates indicate recruitment of emerging adults with T1D and their support persons is feasible - 79% of emerging adults who screened as eligible enrolled and 70% of enrolled emerging adults invited a support person. Emerging adults completed 98% of coaching sessions, and response rates to automated text messages were median 85% IQR [68%, 90%]. Changes in selected measures for outcomes of interest were in expected directions suggesting sensitivity to changes occasioned by the intervention in a future evaluative trial. Emerging adults said FAMS-T1D helped with setting realistic goals, motivated them to prioritize diabetes goals, and increased support, indicating acceptability of the intervention in this new disease and developmental context. Conclusions: Findings suggest potential for FAMS-T1D to engage emerging adults and their support persons and feasibility for evaluation of effects on hypothesized intervention targets and outcomes in a subsequent evaluative trial. Trial Registration: We did not register this study on clinicaltrials.gov because the purpose of the study was to assess the feasibility and acceptability of the intervention and study procedures and measures in preparation for a future trial. The purpose of that future trial will be to evaluate the effect of the intervention on health-related biomedical and behavioral outcomes and that trial will be registered accordingly.

Executive Functioning, Daily Self-Regulation, and Diabetes Management while Transitioning into Emerging Adulthood.

BACKGROUND: Executive functioning (EF) predicts better Type 1 diabetes (T1D) management in the high-risk years after high school, but the daily self-regulation processes involved are unclear. PURPOSE: To examine whether EF is associated with daily self-regulation that minimizes one's exposure or buffers adverse reactions to daily diabetes problems, and to determine whether these patterns become stronger during the transition out of high school. METHODS: A measurement burst design with convenience sampling was used. Seniors in high school with T1D (N = 207; 66% female) completed self-report (i.e., Behavioral Rating Inventory of Executive Functioning) and performance measures of EF (i.e., Delis-Kaplan Executive Function System). A 14-day daily diary assessing self-regulation failures, diabetes problems, affect, and indicators of diabetes management was completed at baseline and 1 year later. RESULTS: Correlations and multilevel modeling were conducted. Lower self-reported EF problems were associated with lower average levels of daily self-regulation failures, and these variables were associated with fewer daily diabetes problems. In contrast, better EF performance was unrelated to average daily self-regulation failures, and was unexpectedly associated with more frequent diabetes problems in year 2. Equally across years, on days participants reported lower than their average levels of daily self-regulation failures, they had fewer diabetes problems, regardless of EF. On days with lower than average diabetes problems, participants reported better diabetes management indicators. EF generally did not buffer daily associations in either year. CONCLUSIONS: Regardless of EF, promoting daily self-regulation may prevent diabetes problems and promote T1D management in daily life at this high-risk transitional time.

Type 1 diabetes (T1D) requires daily self-regulation (e.g., remembering to check blood glucose; regulating emotions, thoughts, and behaviors when diabetes problems arise). These processes draw on executive function (EF) abilities, which may be challenged after high school, when youth experience many life transitions while managing diabetes more independently from parents. The study examined how EF is associated with daily diabetes management as youth transition out of high school. Seniors in high school with T1D completed measures of EF and two 14-day daily diaries, one in the senior year and one the following year. Each evening, participants completed an online survey reporting on self-regulation failures (e.g., forgetting to test blood glucose), diabetes problems, and diabetes management over the past 24 hr. Those with better self-reported EF had lower self-regulation failures and fewer diabetes problems on average. On days with lower self-regulation failures, participants had fewer diabetes problems. On days with fewer diabetes problems, participants reported lower negative emotions, higher confidence in diabetes management, and better self-care behaviors and blood glucose levels. These daily associations occurred regardless of EF. Providing youth with training in self-regulation to prevent daily diabetes problems may promote T1D management during this high-risk transition.

Parent affective responses to observed adolescent disclosures in the context of type 1 diabetes management.

Rates of Type 1 diabetes are rising, and diabetes management often deteriorates during adolescence. Adolescent disclosure to parents is a key factor for effective diabetes management, and parent affective responses to disclosures affect the timing of future disclosures in healthy populations, but no studies to our knowledge have examined parent affective behaviors that facilitate or inhibit disclosure in the context of managing Type 1 diabetes. The present study examined how observed parental affective responses to adolescent disclosures predict the timing of subsequent disclosures during a discussion task in a sample of adolescents with Type 1 diabetes and their parents (N = 66 dyads). Generalized linear mixed models were used to test whether increased or decreased levels of parent affect relative to their emotional baseline response to adolescent disclosures predicted the timing of subsequent disclosures. Adolescents took longer to disclose again when parents responded to prior adolescent disclosures with higher levels of anger and of positive affect relative to their baseline levels of these emotions. Findings suggest that parental affective responses to disclosures have implications for adolescent disclosure in the context of chronic illness management.

Daily diabetes-specific family conflict, problems, and blood glucose during adolescence.

Diabetes-related family conflict is widely regarded as a risk factor for diabetes outcomes, yet it has not been examined on a daily basis. Parental acceptance may attenuate the degree to which family conflict is associated with diabetes outcomes. The present study examined (a) within- and between-person fluctuations in diabetes problems and family conflict, (b) within- and between-person links between conflict and blood glucose (BG) mean, and (c) whether parental acceptance moderated these associations. One hundred eighty adolescents (Mage = 12.92 years) with T1D completed a 14-day diary measuring diabetes problems, conflict with mother, conflict with father, and parental acceptance at the end of each day. Daily average BG values were calculated from glucometer readings. Higher diabetes problems on average across the 14-day diary were associated with more average conflict with mothers (between-person), but daily fluctuations in the number of diabetes problems were not related to daily conflict (within-person). Adolescents with higher conflict with mothers and fathers on average across the 14 days had higher BG means (between-person); however, on days when adolescents reported higher conflict, they had greater risk for low BG (within-person). Daily parental acceptance did not moderate associations between problems and conflict nor conflict and BG mean. This study was the first to examine daily diabetes-specific conflict with mothers and fathers during adolescence. The number of diabetes problems did not predict daily conflict. Fluctuations in daily conflict were associated with greater risk for low BG, underscoring the need for future research examining in-the-moment relations among conflict and BG extremes.

Division of Type 1 Diabetes Responsibility in Latinx and Non-Latinx White Mother-Adolescent Dyads.

Incidence rates of type 1 diabetes are increasing faster in Latinx youth than other ethnic groups, yet this population remains understudied. The current study (1) tested differences in division of diabetes-related responsibility (adolescent alone, mother alone, and shared) across Latinx and non-Latinx White families (N = 118 mother-adolescent dyads, 56 = Latinx dyads, Mage=13.24 years), and (2) examined associations between diabetes responsibility and adolescent health (HbA1c, diabetes self-management behaviors, and depressive symptoms). Latina mothers reported more shared and less adolescent responsibility than non-Latinx White mothers, but there were no ethnic differences in adolescent reports of responsibility. Independent of demographic and illness-related characteristics, mother- and adolescent-reports of shared responsibility were associated with higher self-management behaviors, while individual responsibility (adolescent or mother alone) was generally associated with lower self-management behaviors. Shared responsibility associations with higher mother-reported self-management behaviors occurred among Latinx families, but not non-Latinx White families. Shared and individual responsibility were not associated with HbA1c or depressive symptoms. The findings suggest the importance of shared responsibility for diabetes management in adolescence, particularly in Latinx families.

Understanding the Roles of Romantic Partners and Parents in the Management of Type 1 Diabetes in Emerging Adults.

During the emerging adulthood of people with type 1 diabetes, long-term romantic partners may be involved in diabetes management in ways that supplant parental involvement. We examined the perspectives of involvement in diabetes management of the parents and romantic partners of 29 emerging adults with type 1 diabetes, using qualitative interviews and an online survey. When the individuals with diabetes were in long-term romantic relationships, their partners were heavily involved in managing diabetes and providing support; however, when the individuals with diabetes were in short-term relationships or not in a relationship, their parents were described as having the biggest positive impact on their diabetes management. Emerging adults described the involvement of their parents and romantic partners in both positive and negative ways. Romantic relationship status is an important but understudied variable in understanding social involvement and its effects on type 1 diabetes management during emerging adulthood.

Parental Relationships, Patient-Centered Communication With Healthcare Providers, and Diabetes Management Across Emerging Adulthood.

OBJECTIVE: To examine whether yearly fluctuations in acceptance from and disclosure to parents were associated with fluctuations in perceptions of patient-centered communication (PCC) with the healthcare provider and whether fluctuations in PCC were associated with self-efficacy, type 1 diabetes self-care, and HbA1c across four annual assessments during early emerging adulthood (EA). METHODS: A total of 228 high school seniors (M age = 17.76 years at time 1) reported on mothers' and fathers' acceptance and diabetes-related disclosure to parents, diabetes self-care, and PCC once per year for 4 years. HbA1c was collected from assay kits. RESULTS: Multilevel models revealed within-person associations such that in years when individuals reported greater maternal acceptance than their average, they reported higher PCC. In addition, between-person differences indicated that individuals who reported more maternal acceptance on average relative to others also perceived greater PCC. Similar associations were found for EAs' reports of fathers. No significant effects were found for disclosure to either mother or father. Yearly fluctuations in PCC were associated with self-efficacy such that in years when perceived PCC was higher, self-efficacy was higher. Between person-effects were found for self-efficacy, self-care, and HbA1c such that individuals who reported more PCC on average relative to others reported higher self-efficacy, better self-care, and lower HbA1c. CONCLUSIONS: Aspects of EA's relationships with parents fluctuate with perceptions of PCC with healthcare providers. Perceived PCC with the healthcare provider may be important in higher self-efficacy, diabetes self-care, and lower HbA1c across the early EA years.

Assignment of provisionally named CDC group NO-1 strains derived from animal bite wounds and other clinical sources, to genera nova in the family Comamonadaceae: description of Vandammella animalimorsus gen. nov., sp. nov. and Franklinella schreckenbergeri gen. nov., sp. nov.

CDC group non-oxidizer (NO)-1 is the provisional name designated in 1993 for phenotypically similar, Gram-stain-negative bacilli recovered primarily from human wound infections after animal bites. Otherwise, this group has been rarely alluded to in recent literature. CDC NO-1 strains had been described as non-motile, asaccharolytic, oxidase-negative, catalase-positive, nitrate-reducing bacilli, with predominate cellular fatty acids of C10 : 0 3OH, C16 : 1 ω7c, C16 : 0 and C18 : 1 ω7c. Only one 16S rRNA gene sequence deposited in NCBI (accession no. DQ054782) had been identified as CDC group NO-1 prior to this study. That sequence was closely related (>99 % identity) to sequences called 'Xenophilus species' from canine (JN713339) and feline (KM461961) oral microbiomes as well as to sequences derived from human strains (this study). Some of the 11 isolates delineated here were recovered from human wound infections subsequent to cat/dog bites; others were from wounds (links to animal bites not described) and two were recovered from dialysates. After 16S rRNA and whole genome sequencing, the isolates were found to be most closely related to each other but fell into two distinct genera assignable to the family Comamonadaceae, provisionally discussed here as CDC group NO-1 and CDC group NO-1-like. The genomes of CDC group NO-1 isolates ranged from 3.08 to 3.38 MB with G+C contents of 65.08-66.92 %; genomes derived from CDC group NO-1-like strains were smaller, ranging from 2.72 to 2.82 Mb with G+C contents of 62.87-63.0 mol%. Based on a polyphasic study of these bacteria, we describe Vandammella animalimorsus gen. nov., sp. nov. and Franklinella schreckenbergeri gen. nov., sp. nov. for these clusters.

Diabetes support from romantic partners during early emerging adulthood.

We examined support for type 1 diabetes in casual versus committed romantic relationships and links to blood glucose, self-care, and affect in 101 young adults (Mage 18.8). Individuals provided survey and daily measures of support and blood glucose and affect during a 14-day diary period. Survey data indicated individuals viewed partners as helpful, with partners in committed relationships rated more helpful than those in casual relationships. Daily assessments indicated partners were seen as only moderately helpful. Individuals in committed relationships discussed diabetes with partners on more diary days than those in casual relationships. When individuals in any relationship type experienced more helpful partner support than their average, they reported higher positive and lower negative affect. However, those in casual relationships also experienced more negative affect and higher mean blood glucose the next day. Results suggest tradeoffs between immediate benefits and subsequent costs of partner support to adults in casual relationships.

Parents' Empathic Accuracy: Associations With Type 1 Diabetes Management and Familism.

OBJECTIVE: To (1) test associations between parents' empathic accuracy for their adolescents' positive and negative emotions and adolescents' physical and mental health (HbA1c, diabetes self-care, and depressive symptoms) in a predominantly Latinx sample of adolescents with type 1 diabetes and their parents, and (2) explore how familism values were associated with parent empathic accuracy and adolescent physical and mental health in this population. METHODS: Parents and adolescents engaged in a discussion about a topic of frequent conflict related to the adolescents' diabetes management. Parents and adolescents subsequently completed a video recall task in which they rated their own and their partner's emotions once per minute; parents' empathic accuracy was calculated from an average discrepancy between parent and adolescent ratings of the adolescent's emotions. Adolescents reported on their depressive symptoms and both parents and adolescents reported on adolescents' diabetes self-care and their own familism values; HbA1c was obtained from medical records. RESULTS: Results from structural equation modeling revealed that parents' empathic accuracy for adolescents' negative (but not positive) emotions was uniquely associated with adolescents' HbA1c, self-care, and depressive symptoms. There was limited evidence that familism was related to parent empathic accuracy or adolescent physical and mental health. CONCLUSIONS: Promoting parents' empathic accuracy for adolescents' negative emotions in the context of type 1 diabetes management may have important implications for adolescents' mental and physical health.

Corynebacterium hindlerae sp. nov., derived from a human granuloma, which forms black colonies and black halos on modified Tinsdale medium but is not closely related to Corynebacterium diphtheriae and related taxa.

Corynebacterium diphtheriae, Corynebacterium belfantii, Corynebacterium rouxii, Corynebacterium ulcerans, Corynebacterium pseudotuberculosis and Corynebacterium silvaticum are the only taxa from among ~121 Corynebacterium species deemed potentially able to harbour diphtheria tox genes. Subsequently tox-gene bearing species may potentially produce diphtheria toxin, which is linked to fatal respiratory distress if a pharyngeal pseudomembrane is formed or toxaemia develops in those unimmunized or under-immunized. Detection of diphtheria toxin-producing species may also invoke a public health response and contact tracing. Recovery of such species from the respiratory tract or other contaminated sources such as non-healing ulcerative wounds are expedited by use of differential and selective media such as modified Tinsdale medium (MTM). This medium is supplemented with potassium tellurite, which supresses most normal flora present in contaminated specimens, as well as l-cystine and thiosulphate. Most diphtheria-tox-gene bearing species grow well on MTM, producing black colonies with a black halo around each colony. This is due to an ability to produce cystinase in the presence of tellurite, cystine and thiosulphate, resulting in black tellurium deposits being observed in the agar. Other Corynebacterium species may/may not be able to grow at all in the presence of tellurite but if able to grow, will have small beige or brownish colonies which do not exhibit black halos. We describe here an unusual non-tox-gene-bearing isolate, NML 93-0612T, recovered from a human wrist granuloma, which produced black colonies with black halos on MTM agar but was otherwise distinguishable from Corynebacterium species which can bear tox genes. Distinctive features included its unusual colony morphology on MTM and sheep blood agar, by proteomic, biochemical and chemotaxonomic properties and by molecular methods. Its genome contained 2 680 694 bytes, a G+C content of 60.65 mol% with features consistent with the genus Corynebacterium and so represents a new species for which we propose the name Corynebacterium hindlerae sp. nov.

Insulin Restriction, Emotion Dysregulation, and Depressive Symptoms in Late Adolescents with Diabetes.

OBJECTIVE: Insulin restriction occurs when an individual takes less insulin than recommended and is a serious concern for those with diabetes. General insulin restriction (IR) and insulin restriction for weight control (IRWC) have not been clearly distinguished in the literature, creating inconsistencies and limited understanding of factors that underlie this behavior. We examined whether these are distinct, and how emotion dysregulation and depressive symptoms relate to both forms of insulin restriction during late adolescence. METHODS: As part of a larger study, late adolescents (ages 17-18) with type 1 diabetes (N = 236) completed measures of depressive symptoms (Center for Epidemiologic Studies-Depression Scale [CES-D]), facets of Difficulties In Emotion Regulation Scale (DERS), diabetes self-management behaviors, insulin restriction, and hemoglobin A1c (HbA1c). RESULTS: IR and IRWC were not significantly associated with each other. IR was associated with self-management behaviors but not HbA1c, whereas the opposite was true for IRWC. All DERS subscales (M = 10.60-16.73) and CES-D (M = 16.56) were correlated with greater IRWC; CES-D and all but one DERS subscale were correlated with IR. Covariation with CES-D explained associations between DERS and IRWC. CES-D moderated associations with IR, indicating most subscales of the DERS were associated with IR only when CES-D was higher. CONCLUSION: Emotion dysregulation and depressive symptoms are important correlates of the dangerous behavior of insulin restriction, but function differently when insulin is restricted specifically for weight control versus nonspecified reasons. Future research to understand these underlying processes will be necessary to develop emotion-based theory and evidence-based interventions for this dangerous behavior.

Qualitative analysis of helpful and unhelpful aspects of social relationships among young adults with type 1 diabetes.

AIMS: Young adulthood is a high-risk time for type 1 diabetes management when individuals are managing diabetes within changing social contexts and new social relationships. This qualitative study examined helpful and unhelpful aspects of social relationships in the daily lives of young adults with type 1 diabetes. METHODS: Semi-structured qualitative interviews with 29 young adults with type 1 diabetes (ages 22-24, mean = 23 years; 55% female) explored: (a) who in the past week was present when diabetes management occurred; (b) what others did that was helpful or unhelpful for diabetes management; (c) what made helpful and unhelpful aspects of social relationships more or less likely; and (d) what young adults disclosed to others about diabetes. RESULTS: Romantic partners and parents were commonly present and helpful in giving reminders and offering instrumental support, but the presence of trusted individuals was also helpful to management. Co-workers and friends were present during episodes of diabetes management but were often unhelpful, especially when lacking knowledge about participants' diabetes or its management. Participants also discussed conflicting and spontaneous changes in schedules were unhelpful to management. Disclosing diabetes to others and planning for social context barriers were described as strategies to facilitate helpful and reduce unhelpful aspects of social relationships. CONCLUSIONS: Young adults face social barriers to management if they are unable to utilize their relationships effectively. Interventions to promote disclosure to trusted others and planning to avoid social context-related barriers to diabetes management may facilitate more effective self-management at this high-risk time of development.

Pseudoxanthomonas winnipegensis sp. nov., derived from human clinical materials and recovered from cystic fibrosis and other patient types in Canada, and emendation of Pseudoxanthomonas spadix Young et al. 2007.

Twelve isolates recovered from 10 cystic fibrosis/other patient types and a variety of clinical sources, were referred to Canada's National Microbiology Laboratory over 7 years. These were assignable to the genus Pseudoxanthomonas but were unidentifiable to species level. Patients included five males and five females from two geographically separated provinces, ranging in age from 2 months to 84 years. In contrast, most Pseudoxanthomonas species described to date have been derived from water, plants or contaminated soils. By 16S rRNA gene sequencing, the patient strains had ≥99.4 % similarity to each other but only 97.73-98.29 % to their closest relatives, Pseudoxanthomonas spadix or Pseudoxanthomonas helianthi. Bacteria were studied by whole genome sequencing using average nucleotide identity by Blastn, digital DNA-DNA hybridization, average amino acid identity, core genome and single nucleotide variant analyses, MALDI-TOF, biochemical and cellular fatty acid analyses, and by antimicrobial susceptibility testing. Bacterial structures were assessed using scanning and transmission electron microscopy. Strains were strict aerobes, yellowish-pigmented, oxidative, non-motile, Gram-stain-negative bacilli and generally unable to reduce nitrate. Strains were susceptible to most of the antibiotics tested; some resistance was observed towards carbapenems, several cephems and uniformly to nitrofurantoin. The single taxon group observed by 16S rRNA gene sequencing was supported by whole genome sequencing; genomes ranged in size from 4.36 to 4.73 Mb and had an average G+C content of 69.12 mol%. Based on this study we propose the name Pseudoxanthomonas winnipegensis sp. nov. for this cluster. Pseudoxanthomonas spadix DSM 18855T, acquired for this study, was found to be non-motile phenotypically and by electron microscopy; we therefore propose the emendation of Pseudoxanthomonas spadix Young et al. 2007 to document that observation.

The Role of Socioeconomic Status in Latino Health Disparities Among Youth with Type 1 Diabetes: a Systematic Review.

PURPOSE OF REVIEW: Type 1 diabetes (T1D) incidence is growing faster among Latino than non-Latino White youth, but ethnic disparities in self-management behaviors and HbA1c are unclear. Socioeconomic status (SES) is a key factor in T1D, which may confound or contribute to disparities in Latino pediatric T1D management. A systematic review examined whether ethnic differences in pediatric T1D outcomes occur and are independent of socioeconomic status (SES). RECENT FINDINGS: Latino youth displayed lower self-management and higher HbA1c in approximately half of the identified studies prior to including SES in analyses. Ethnic differences in self-management were found for objective (i.e., frequency of blood glucose checks), but not subjective measures. Ethnic differences were often eliminated when SES was statistically controlled. SES moderated some differences, suggesting complex sociocultural processes. Articles varied widely in SES measures and the analytic methods used to evaluate ethnic disparities. Pediatric Latino T1D disparities are inconsistent and at least partially dependent on the SES context. Recommendations for future research to systematically evaluate SES and Latino T1D disparities are made.

Enemella gen. nov., Enemella evansiae sp. nov., Enemella dayhoffiae sp. nov. and Parenemella sanctibonifatiensis gen. nov., sp. nov., novel taxa assignable to the family Propionibacteriaceae and derived from human clinical samples.

Nine Gram-stain-positive cocci, coccobacilli or short, rod-shaped strains recovered from clinical sources from patients located in two Canadian provinces and one environmental source were extensively studied. Clinical sources included blood cultures, cerebral spinal fluid, lymph node, lung biopsy and peritoneal fluid. Through 16S rRNA gene and whole genome sequencing analyses, the strains were found to cluster into three groups, closest to but distinguished from other genera in the family Propionibacteriaceae. The genomes from these bacteria had high G+C content, ranging from 67.8-69.56 mol%, and genome sizes of 3.02-4.52 Mb. Biochemical and chemotaxonomic properties including branched-chain cellular fatty acids, l-lysine diaminopimelic acid (ll-DAP) and cell-wall type A3γ (ll-DAP-gly) containing ll-DAP, alanine, glycine and glutamic acid were found and so the strains were therefore deemed to be consistent with other new genera in this family. Based on this investigation, we propose Enemella gen. nov., Enemella evansiae sp. nov., Enemella dayhoffiae sp. nov. and Parenemella sanctibonifatiensis gen. nov., sp. nov. for these taxa. Misidentified taxon 'Ponticoccus gilvus' was found to be assignable to Enemella evansiae based on this study.

Neighborhood disadvantage, parent-adolescent relationship quality, and type 1 diabetes in late adolescents transitioning to early emerging adulthood.

OBJECTIVE: We examined whether neighborhood disadvantage predicted subsequent levels, and longitudinal trajectories, of type 1 diabetes (T1D) outcomes among late adolescents transitioning into early emerging adulthood. We also examined whether such associations occur indirectly through parent-adolescent relationship quality. RESEARCH DESIGN & METHODS: Seniors in high school with T1D (N = 236; mean age 17.76 ± 0.39 years; 61% female; 73.7% non-Latino White) completed selfreport measures of relationship quality with mothers and fathers, and adherence to their diabetes regimen; glycemic control was measured using HbA1c assay kits. Both T1D outcomes (i.e. adherence, HbA1c) were assessed annually across three time points (two years). Census tract indicators of neighborhood disadvantage (e.g., % unemployed) were culled from participant addresses at baseline linked to American Community Survey data. Structural Equation Modeling was used to estimate direct and indirect links between neighborhood disadvantage, relationship quality, and both subsequent levels (i.e., intercepts centered at Time 2), and trajectories of T1D outcomes (i.e., slopes across three time points). RESULTS: All models showed excellent fit to the data. Greater neighborhood disadvantage associated with lower relationship quality with both parents. Lower relationship quality with fathers (but not with mothers) measured at Time 1 predicted poorer levels of adherence and HbA1c at Time 2, and formed an indirect path linking neighborhood disadvantage to each Time 2 outcome. Neighborhood disadvantage and parent-adolescent relationship quality during high school did not predict longitudinal trajectories of T1D outcomes across all three time points. CONCLUSIONS: Parent-adolescent relationship quality (especially with fathers) remains important for T1D outcomes among late adolescents on the cusp of emerging adulthood, but may be at risk among those living within a socioeconomically-disadvantaged neighborhood.

Description of Eikenella halliae sp. nov. and Eikenella longinqua sp. nov., derived from human clinical materials, emendation of Eikenella exigua Stormo et al. 2019 and emendation of the genus Eikenella to include species which are strict anaerobes.

The Haemophilus, Aggregatibacter, Cardiobacterium, Eikenella, Kingella (HACEK) group genus Eikenella contained a single species, Eikenella corrodens, for many years. In November 2019, Eikenella exigua was described after recovery from a brain abscess and blood culture in Norway. Coincidentally, characterization of 22 Gram-negative bacteria resembling Eikenella from 17 Canadian patients had been underway. Seven isolates from five patients were conclusively identifiable as E. corrodens. One (NML 120819) was deemed to represent a species of the genus Eikenella most closely related to E. corrodens. Fourteen isolates had 97.6 to 98.8% similarities to E. corrodens by 16S rRNA gene sequencing, forming three distinct groups by genome analyses. The largest contained ten anaerobic isolates from eight patients recovered from blood, brain, bone and other abscesses; upon re-evaluation, this group was found to be most consistent with E. exigua. A second facultatively anaerobic clade consisted of two ocular isolates from one patient and a sinus isolate from a second patient. The third taxon consisted of a single strictly anaerobic blood culture isolate. The novel taxa, like E. corrodens, were poorly reactive biochemically and difficult to discern from each other phenotypically and chemotaxonomically, including by cellular fatty acids. MALDI-TOF (Bruker) and whole-genome sequencing were used to further characterize isolates. Draft genomes for the strains had similar DNA G+C contents (55.38-58.53 mol%) while sizes varied from 1.82 Mb to 2.54 Mb. We propose here emendations of the genus Eikenella and the species Eikenella exigua, as well as describing Eikenella halliae sp. nov. NML 130454T (=LMG 30894T=NCTC 14180T) and Eikenella longinqua sp. nov. NML 02-A-017T (=LMG 30896T=NCTC 14179T), on the basis of these findings.

The separation in coordination between social- and self-regulation for emerging adults with type 1 diabetes.

To examine how self-regulation and social-regulation surrounding type 1 diabetes (T1D) management are coordinated during early emerging adulthood and whether classes of coordination relate to HbA1c and executive functioning (EF). Emerging adult participants (N = 212) with T1D (M age = 18.8 years, SD = .40) completed a 14-day diary to capture components of self-regulation and social-regulation. A mixture multi-level latent coordination model first determined the separate but coordinated factor structure of self- and social-regulation, then determined the number of distinct classes of coordination and how those classes linked to HbA1c and EF. The best-fitting model included three coordinative factors (self, mother, and father) of regulation and two distinct classes. The class with lower HbA1c and higher EF had more stable self- and social-regulation, more connections between self- and social-regulation and reflected more adaptive patterns, consistent with medical management goals. Social connection with parents may aid in regulation during this at-risk transitional time of emerging adulthood.
