AIM: The goal of the present longitudinal cohort study was to examine patterns of periodontal disease progression at progressing sites and subjects defined based on linear mixed models (LMM) of clinical attachment loss (CAL) METHODS: 113 periodontally healthy and 302 periodontitis subjects had their CAL calculated bi-monthly for 12 months. LMMs were fitted for each site and the predicted CAL levels used to categorize their progression state. Participants were grouped based on the number of progressing sites into unchanged, transitional and active subjects. Patterns of periodontal disease progression were explored using descriptive statistics RESULTS: Progression occurred primarily at molars (50% of progressing sites) and interproximal sites (72%), affected a higher proportion of deep than shallow sites (2.7% vs. 0.7%), and pocketing was the main mode of progression (49%). We found a low level of agreement (47%) between the LMM and traditional approaches to determine progression such as change in CAL >/=3 mm. Fourteen percent of subjects were classified as active and among those 93% had periodontitis. The annual mean rate of progression for the progressing subjects was 0.35 mm/year CONCLUSION: Progressing sites and subjects defined based on LMMs presented patterns of disease progression similar to those previously reported in the literature.

BACKGROUND AND OBJECTIVES: A recent AAP policy statement recommends mL-exclusive dosing for pediatric liquid medications. Little is known about parent preferences regarding units, perceptions about moving to mL-only, and the role of health literacy and prior mL-dosing experience. METHODS: Cross-sectional analysis of data collected as part of a randomized controlled study in 3 urban pediatric clinics (SAFE-Rx for Kids study). English/Spanish-speaking parents (n=493) of children <8 years were randomized to 1 of 4 study arms and given labels/dosing tools which varied in label instruction format (text+pictogram, text-only) and units (mL-only, mL/tsp). OUTCOMES: teaspoon preference in dosing instructions, perceived difficulty with mL-only dosing. Predictor variable: health literacy (Newest Vital Sign; low[0-1], marginal[2-3], adequate[4-6]). Mediating variable: prior mL-dosing experience. RESULTS: Over two-thirds of parents had low or marginal health literacy. The majority (>70%) preferred to use mL, perceived mL-only dosing to be easy, and had prior mL-dosing experience; 11.5% had a teaspoon preference, 18.1% perceived mL-only dosing will be difficult, and 17.7% had no prior mL-dosing experience. Parents with lower health literacy had a higher odds of having a teaspoon preference (low vs. adequate: AOR=2.9[1.3-6.2]), and greater odds of perceiving difficulty with mL-only dosing (low vs. adequate: AOR=13.9[4.8-40.6]), marginal vs. adequate: AOR=7.1[2.5-20.4]). Lack of experience with mL-dosing partially mediated the impact of health literacy. CONCLUSIONS: Most parents were comfortable with mL-only dosing. Parents with low health literacy were more likely to perceive mL-only dosing to be difficult; educational efforts will need to target this group to ensure safe medication use.

OBJECTIVES/OBJECTIVE:Many children in low- and middle-income countries fail to reach their developmental potential. We sought to determine if a parenting program focused on the promotion of reading aloud enhanced parent-child interactions and child development among low-income families in northern Brazil. METHODS:This was a cluster-randomized study of educational child care centers randomly assigned to receive an additional parenting program (intervention) or standard child care without a parenting component (control). Parent-child dyads were enrolled at the beginning of the school year and were assessed at enrollment and at the end of the school year. Families in intervention centers could borrow children's books on a weekly basis and could participate in monthly parent workshops focused on reading aloud. We compared parents and children in intervention and control centers 9 months after the start of the intervention on measures of parent-child interaction and child language, cognitive, and social-emotional development. RESULTS:= 0.33). CONCLUSIONS:An innovative program focused on the promotion of parent-child reading aloud resulted in benefits to parent-child interactions and to child language and cognitive development that were greater than those provided by educational child care alone. This promising approach merits further evaluation at scale.

Early brain activity is crucial for neurogenesis and the development of brain networks. However, it has been challenging to localize regions in the developing human brain that contribute to spontaneous waves of neuronal activity. Recently, Arichi and colleagues reported that the temporal and heteromodal insular cortices have a central role in propagating these neural instructional signals.

Early academic achievement has been shown to predict high school completion, but there have been few studies of the predictors of early academic success focused on Latino students. Using longitudinal data from 750 Mexican and Dominican American families, this study examined a cultural model of parenting and early academic achievement. While Latino students were achieving in the average range as a whole, certain subgroups (e.g., Dominicans, boys) were at higher risk for underachievement. Results highlighted the protective role of authoritative parenting, which was associated with academic and social-emotional school readiness, both of which predicted higher achievement at the end of first grade. The role of respeto and authoritarian parenting practices in academic achievement at first grade differed between Mexican and Dominican American families. Findings advance understanding of early achievement and parenting among Latino families from a cultural perspective.

AIMS/HYPOTHESIS: In addition to blood glucose concentrations measured in the fasting state and 2 h after an OGTT, intermediate measures during an OGTT may provide additional information regarding a person's risk of future diabetes and cardiovascular disease (CVD). First, we aimed to characterise heterogeneity of glycaemic patterns based on three time points during an OGTT. Second, we compared the incidences of diabetes and CVD and all-cause mortality rates among those with different patterns. METHODS: Our cohort study included 5861 participants without diabetes at baseline from the Danish Inter99 study. At baseline, all participants underwent an OGTT with measurements of plasma glucose levels at 0, 30 and 120 min. Latent class mixed-effects models were fitted to identify distinct patterns of glycaemic response during the OGTT. Information regarding incident diabetes, CVD and all-cause mortality rates during a median follow-up time of 11, 12 and 13 years, respectively, was extracted from national registers. Cox proportional hazard models with adjustment for several cardiometabolic risk factors were used to compare the risk of diabetes, CVD and all-cause mortality among individuals in the different latent classes. RESULTS: Four distinct glucose patterns during the OGTT were identified. One pattern was characterised by high 30 min but low 2 h glucose values. Participants with this pattern had an increased risk of developing diabetes compared with participants with lower 30 min and 2 h glucose levels (HR 4.1 [95% CI 2.2, 7.6]) and participants with higher 2 h but lower 30 min glucose levels (HR 1.5 [95% CI 1.0, 2.2]). Furthermore, the all-cause mortality rate differed between the groups with significantly higher rates in the two groups with elevated 30 min glucose. Only small non-significant differences in risk of future CVD were observed across latent classes after confounder adjustment. CONCLUSIONS/INTERPRETATION: Elevated 30 min glucose is associated with increased risk of diabetes and all-cause mortality rate independent of fasting and 2 h glucose levels. Therefore, subgroups at high risk may not be revealed when considering only fasting and 2 h glucose levels during an OGTT.

CONTEXT: A diagnosis of advanced chronic kidney disease (CKD), or end stage renal disease (ESRD) represents a significant life change for patients and families. Individuals often experience high symptom burden, decreased quality of life, increased health care utilization, and end-of-life care discordant with their preferences. Early integration of palliative care with standard nephrology practice in the outpatient setting has the potential to improve quality of life through provision of expert symptom management, emotional support, and facilitation of advance care planning that honors the individual's values and goals. OBJECTIVES: This special report describes application of participatory action research (PAR) methods to develop an outpatient integrated nephrology and palliative care program. METHODS: Stakeholder concerns were thematically analyzed to inform translation of a known successful model of outpatient kidney palliative care to a practice in a large, urban medical center in the United States. RESULTS: Stakeholder needs and challenges to meeting these needs were identified. We uncovered a shared understanding of the clinical need for palliative care services in nephrology practice, but apprehension towards practice change. Action steps to modify the base model were created in response to stakeholder feedback. CONCLUSIONS: The development of a model of care that provides a new approach to clinical practice requires attention to relevant stakeholder concerns. PAR is a useful methodological approach that engages stakeholders and builds partnerships. This creation of shared ownership can facilitate innovation and practice change. We synthesized stakeholder concerns to build a conceptual model for an integrated nephrology and palliative care clinical program.

OBJECTIVE:There is suggestive evidence linking hypoglycemia with cardiovascular disease, but few data have been collected in a community-based setting. Information is lacking on individual cardiovascular outcomes and cause-specific mortality. RESEARCH DESIGN AND METHODS:We conducted a prospective cohort analysis of 1,209 participants with diagnosed diabetes from the Atherosclerosis Risk in Communities (ARIC) study (analytic baseline, 1996-1998). Severe hypoglycemic episodes were identified using first position ICD-9 codes from hospitalizations, emergency department visits, and ambulance calls through 2013. Cardiovascular events and deaths were captured through 2013. We used adjusted Cox regression models with hypoglycemia as a time-varying exposure. RESULTS:There were 195 participants with at least one severe hypoglycemic episode during a median fellow-up of 15.3 years. After severe hypoglycemia, the 3-year cumulative incidence of coronary heart disease was 10.8% and of mortality was 28.3%. After adjustment, severe hypoglycemia was associated with coronary heart disease (hazard ratio [HR] 2.02, 95% CI 1.27-3.20), all-cause mortality (HR 1.73, 95% CI 1.38-2.17), cardiovascular mortality (HR 1.64, 95% CI 1.15-2.34), and cancer mortality (HR 2.49, 95% CI 1.46-4.24). Hypoglycemia was not associated with stroke, heart failure, atrial fibrillation, or noncardiovascular and noncancer death. Results were robust within subgroups defined by age, sex, race, diabetes duration, and baseline cardiovascular risk. CONCLUSIONS:Severe hypoglycemia is clearly indicative of declining health and is a potent marker of high absolute risk of cardiovascular events and mortality.

OBJECTIVE:Sexual minority men (SMM) in the United States continue to experience adverse health problems and psychosocial burdens. However, there is limited psychometric research seeking to quantify the life worries of this population. Informed by syndemic theory, the Life Worries Scale (LWS) was developed to measure the concerns of young SMM. METHOD/METHODS:Analyses of the scale were undertaken using baseline data (n = 665) from an ongoing cohort study of emerging adult, SMM. RESULTS:Exploratory factor analyses (EFA) of an initial set of 24 Likert-type items, followed by confirmatory factor analysis (CFA) and an exploratory structural equation model (ESEM), indicated a structure consisting of 6 domains of worries: financial stability, social stability, self esteem, loneliness, physical appearance, and physical health. These 6 subscales were highly correlated and also demonstrated high levels of internal consistency. Differences in life worries were noted across demographic states, specifically HIV serostatus, sexual attraction, housing status, and self-rated health. High levels of association were also detected between all 6 subscales with both depression and PTSD, while significant correlations were detected between suicidality and both self esteem and loneliness related worries. CONCLUSIONS:The results of our analyses provide evidence for the strong psychometric characteristics of the LWS. This newly developed instrument should be utilized in research to examine the extent to which life worries explain health outcomes and risk behaviors in sexual minority males, and may be potentially extended for use in other populations.
